TY - JOUR T1 - Influence of Tillage and Daily Manure Application on the Survival of Bacterial Pathogens Indicators in Soil and on Radish AN - 954602756; 14107572 AB - We measured Escherichia coli, and Enterococcus sp. numbers in soil and on fresh radish (Raphanus sativus L.) at 1, 7, 14, 28, 54, and 84 days after the addition of high and low amounts of solid dairy manure in combination with chisel tillage to a 20 cm depth (deep) or roller tillage to a 10 cm depth (shallow). When the high or low amount of solid dairy manure was added to the soil, E. coli populations in soil were higher in the 54 days following manure addition compared to the control treatment. Dairy manure addition increased Enterococcus sp. in soils compared to the control treatment for the entire 84 days sampling period. At harvest, which was 84 days after application, we did not detect E. coli in radish in rhizosphere soil or on radish roots. Addition of solid dairy manure increased Enterococcus sp. numbers in radish rhizosphere soil and on radish roots. We suggest that fresh animal manure be applied to soil at least 120 days prior to planting to allow die-off of human pathogenic bacteria and reduce the incidence of bacterial adhesion on or bacterial colonization of ready to eat vegetables.

Petota) AN - 923196148; 14044515 AB - times Premise of the study: The taxonomy of cultivated potatoes has been highly controversial, with estimates of species numbers ranging from 3 to 17. Ploidy level has been one of the most important taxonomic characters to recognize cultivated potato species, containing diploid (2n = 2x = 24), triploid (2n = 3x = 36), tetraploid (2n = 4x = 48), and pentaploid (2n = 5x = 60) cultivars. We tested the environmental associations of different ploidy levels in cultivated potato species that traditionally have been recognized as Linnaean taxa to see whether, in combination with prior morphological, molecular, and crossing data, some of the ploidy variants can be recognized as distinct taxa. times METHODS: We summarize 2780 chromosome counts of landrace cultivated potatoes, provide georeferences to 2048 of them, and analyze these data for 20 environmental variables at 10-min resolution using the randomForest algorithm to explore associations with taxa and ploidy variants. times Key results: Except for the S. tuberosum Chilotanum Group and extreme northern and southern range extensions of the Andigenum Group, it is impossible to find distinct habitats for the ploidy variants of the S. tuberosum Andigenum Group. times CONCLUSIONS: Our distributional and ecological data, in combination with prior results from morphology, microsatellites, and crossing data, provide yet additional data to support a major reclassification of cultivated potato species. A rational, stable, and universally accepted taxonomy of this major crop plant will greatly aid all users of wild and cultivated potatoes from breeders to gene bank managers to ecologists and evolutionary biologists.

Physical activity and dietary change programs also have generally had small effects, if any. Innovative procedures are needed to turn this situation around. Video games offer promise of enhancing intervention effects by capturing childrens' attention through immersive stories, offering fun as an incentive to play the games, and exposing them to diverse behavior change procedures inserted into the game experience. This presentation will describe "Escape from Diab" and "Nanoswarm: Invasion from Inner Space", two obesity prevention games, which have been demonstrated to influence dietary intake in a pilot study. A brief overview will also be provided about our several other video game projects. Substantial research is needed to learn how optimally to design video games to minimize health related behavior changes. JF - Acta Universitatis Palackianae Olomucensis.

We compared emerald ash borer (EAB), Agrilus planipennis Fairmaire (Coleoptera: Buprestidae), adult performance and preference among seedlings of the three ash species, and then related performance and preference to foliage nutritional quality and defensive compounds. Longevity of EAB adults reared on green and white ash was found to be greater than on black ash. EAB adult females also seemed to show feeding preference among the three species of ash trees because the total foliage area consumption was greater on green ash and white ash compared to black ash in dual-choice tests; however, the total mass of foliage consumed did not differ. The foliage of all ash species was high in nitrogen and in most macro- and micro-nutrients studied. The patterns of EAB performance and preference did not correspond to any of the individual chemical compounds tested (nitrogen, proteins, most macro- and micro-nutrients, or putative defensive compounds of ash seedlings). Nevertheless, greater longevity of EAB adults on green and white ash compared to black ash was probably related to unbalanced nutrients (total nitrogen/total non-structural carbohydrate ratio) of black ash. Putative defensive compounds (i.e., phenolics and protease inhibitors) did not contribute to EAB longevity in this study, probably because (1) EAB adults were able to excrete most of these compounds and (2) their effects were alleviated by high nitrogen levels. More research is needed to elucidate the interactions of nitrogen and carbohydrate levels, and the interactions of nutrient balance and defensive plant allelochemicals on EAB performance and preference.

They discuss the development of earlier protocols, their modifications, and the extent to which a given protocol pertains to different conditions. Emphasis is given to the considerations that led to a choice of reagents for each step and to their order in the sequence. Published studies are used as case studies to critically evaluate the implied geochemical components of operationally defined extraction steps. Also assessed are possible effects of subsequent extraction steps and conditions on the selective dissolution of the solid components and their operational definitions.

The mode of action of DFMs involves multiple mechanisms, including direct inhibition of enteric pathogens and indirectly through competitive exclusion of pathogens by the normal gut microbiota. Additionally, recent basic research efforts have focused on the effects of DFMs on promoting host immunity and on the complex interactions between the gut microflora and immune system development. This review will summarize the latest developments in DFM studies with particular emphasis on the underlying mechanisms of immune enhancement.

The objectives of this study were to (a) develop an improved methodology (HPS) to estimate the fractions of sn and ss in the sediment discharge, and (b) compare HPS predictions to those of LM (Leys and McTainsh, 1996) and CN (Chepil and Woodruff, 1978; Nickling, 1978) that included or FS (Fryrear and Saleh, 1993) that excluded size measurements of the trapped sediment. Sediment flux profiles from nine field studies in four states were used in the data analyses. The log form of the ss flux profile developed in the LM method for dispersed particles had poor data fit to profiles of aggregated particles. The FS, HPS, and CN methods predicted significantly different ratios of ss discharge to total discharge in the order FS HPS CN. The widely-used power form of the ss flux profile in the CN method provided a good data fit above 0.1 m, but over estimated ss flux near the surface. The FS method over estimated sn and under estimated ss components. The HPS method obtained good fits to the data, even when profile gradients were large. Thus, using the sieved sediment catch from passive sediment catchers coupled with HPS analysis methodology offered significant improvements in the accuracy of estimates of sn and ss discharge. On short fields, the fraction of ss discharge was related to soil texture.

Pasteurization is used to inhibit microbial growth in milk, and an open question is whether milk pasteurization inactivates Shiga toxins. To answer this question we measured Shiga toxin's inhibition effect on Vero cell dehydrogenase activity and protein synthesis. Our data demonstrate that Shiga toxin 2 (Stx2) is heat-stable and that pasteurization of milk, at the various suggested temperatures and times by the U.S. Food and Drug Administration, (63 degree C for 30 min, or 72 degree C for 15 s or 89 degree C for 1 s), did not reduce the biological activity of Stx2. However, treatment at 100 degree C for 5 min inactivated the toxin. These data demonstrate that Stx2 is not inactivated by conventional pasteurization.

We sampled 60 headwater tributaries in the South Fork Trinity River, a 2,430 km super(2), mostly forested, multiple-use watershed in northwestern California. Our objectives were: (1) to differentiate unique headwater types using 69 abiotic and vegetation variables measured at three spatial scales, and then to reduce these to informative subsets; (2) determine if distinct biota occupied the different tributary types; (3) determine the environmental attributes associated with the presence and abundance of these biotic assemblages; and (4) using niche modeling, determine key attribute thresholds to illustrate how these biota could be employed as metrics of system integrity and ecological services. Several taxa were sufficiently abundant and widespread to use as bio-indicators: the presence and abundance of steelhead trout (Oncorhynchus mykiss), herpetofauna (reptile and amphibian) species richness, and signal crayfish (Pacifastacus leniusculus) represented different trophic positions, value as commercial resources (steelhead), sensitivity to environmental stress (amphibians), and indicators of biodiversity (herpetofauna species richness). Herpetofauna species richness did not differ, but abundances of steelhead trout, signal crayfish, and amphibian richness all differed significantly among tributary types. Niche models indicated that distribution and abundance patterns in both riparian and aquatic environments were associated with physical and structural attributes at multiple spatial scales, both within and around reaches. The bio-indicators responded to unique sets of attributes, reflecting the high environmental heterogeneity in headwater tributaries across this large watershed. These niche attributes represented a wide range of headwater environments, indicating responses to a number of natural and anthropogenic conditions, and demonstrated the value of using a suite of bio-indicators to elucidate watershed conditions, and to examine numerous disturbances that may influence ecological integrity.Original Abstract: Las cabeceras pueden representar el 80% de los kilometros de recorrido en una cuenca fluvial y poseen unas propiedades fisicas y biologicas unicas, cuya importancia hasta hace poco no se habian reconocido para el sostenimiento de un funcionamiento sano de las redes de cuencas y sus servicios ecologicos. Tomamos muestras de 60 cabeceras de los afluentes del rio South Fork Trinity, una cuenca de 2.430 km super(2), boscosa en su mayor parte y de multiples usos, situada en el noroeste de California. Nuestros objetivos eran: (1) diferenciar tipos de cabeceras unicos utilizando 69 variables abioticas y vegetales, medidas a tres escalas espaciales, y luego reducirlos a subconjuntos informativos; (2) determinar si distintos biotas ocupaban los distintos tipos de afluentes; (3) determinar las caracteristicas medioambientales asociadas con la presencia y abundancia de dichas comunidades bioticas; y (4) utilizando una modelizacion de nichos, determinar los umbrales de los atributos claves para ilustrar como estos biotas podrian emplearse para la medicion de la integridad del sistema y los servicios ecologicos. Varios taxones fueron suficientemente abundantes y extendidos para utilizarlos como bioindicadores; la presencia y abundancia de la trucha arco iris (Oncorhynchus mykiss), la riqueza en especies de la herpetofauna (reptiles y anfibios) y el cangrejo senal (Pacifastacus leniusculus), representaban diferentes posiciones troficas, el valor como recursos comerciales (la trucha arco iris), la sensibilidad al estres ambiental (anfibios), e indicadores de la biodiversidad (riqueza de especies de la herpetofauna). La riqueza de especies de la herpetofauna no difirio, pero la abundancia de la trucha arco iris, del cangrejo senal, la riqueza de anfibios, difirieron significativamente entre los tipos de afluentes. Los modelos de los nichos indicaron que los patrones de distribucion y abundancia, tanto en los ambientes acuaticos como en los riberenos, estaban asociados con atributos fisicos y estructurales a multiples escalas espaciales, tanto dentro como alrededor de los tramos acuaticos. Los bioindicadores respondieron a series unicas de atributos, reflejando la elevada heterogeneidad ambiental en las cabeceras de los afluentes en toda esta gran cuenca. Dichos atributos de los nichos representaban una amplia gama de ambientes de cabeceras fluviales, indicando respuestas a una serie de condiciones naturales y antropogenicas. Se demostro el valor de utilizar una serie de bioindicadores para elucidar las condiciones de las cabeceras y para examinar las numerosas perturbaciones que pueden influir sobre la integridad ecologica.

Until now, it has been generally accepted that the dinucleotide signature is characteristic of a genome and is relatively homogeneous across a genome. However, we found some local regions of the soybean genome with a signature differing widely from that of the rest of the genome. Those regions were mostly centromeric and pericentromeric, and enriched for repetitive sequences. We found that DNA binding energy also presented large-scale patterns across soybean chromosomes. These two patterns were helpful during assembly and quality control of soybean whole genome shotgun scaffold sequences into chromosome pseudomolecules.

However, research on indirect effects has been heavily biased toward top-down trophic interactions, and less is known about other indirect-interaction pathways. As autogenic ecosystem engineers, plants can serve as initiators of nontrophic indirect interactions that, like top-down pathways, can involve both trait-mediated indirect interactions (TMIIs) and density-mediated indirect interactions (DMIIs). Using microcosms, I examined a plant -> predator -> consumer interaction pathway involving the exotic autogenic ecosystem engineer Centaurea maculosa; native Dictyna spiders (which exhibit density and trait [web-building] responses to C. maculosa); Dictyna's insect prey, Urophora affinis; and Urophora's host plant (a secondary receiver species) to quantify DMIIs and TMIIs in an autogenic engineered pathway. Both DMIIs and TMIIs were strong enough to reduce Urophora populations, but only DMIIs, which were 4.3 times stronger than TMIIs, were strong enough to also reduce Urophora's fecundity and increase the fecundity of its host plant. Prior field studies support these results, suggesting that the differences between DMIIs and TMIIs are even stronger in nature. This study illustrates that autogenic ecosystem engineers can initiate powerful indirect interactions that generally parallel predator-initiated interactions but also differ in important functional ways.

This inhibitory effect of prepared modified zeolites is caused by the formation of ROS. It was found that the above-mentioned zeolites despite their inhibitory action protect the algal growth in surroundings containing 4-chlorophenol (4-CP). This effect was manifested by increasing IC sub(50) values of 4-CP on algal growth with respect to control samples without zeolite. Both modified zeolites with incorporated thiophene or pyrrole exhibited approximately equal protection effects. It was suggested that the reason for this protection effect is the ability of these zeolites to decompose 4-CP in water surroundings by visible light.

Immunologic responses after inoculation demonstrated significantly greater (P < 0.05) antibody and proliferative responses to RB51 antigens in cattle vaccinated with RB51 than in the controls. Pregnant cattle received a conjunctival challenge at approximately 6 months of gestation with 107 CFU of B. suis bv. 1 strains isolated from naturally infected cattle. The fluorescence polarization assay and the buffered acid plate agglutination test had the highest sensitivities in detecting B. suis-infected cattle between 2 and 12 weeks after experimental infection. Serologic responses and lymphocyte proliferative responses to B. suis antigens did not differ between control and RB51 vaccinees after experimental infection. No abortions occurred in cattle in either treatment group after challenge, although there appeared to be an increased incidence of retained placenta after parturition in both the control and the RB51 vaccination treatment groups. Our data suggest that the mammary gland is a preferred site for B. suis localization in cattle. Vaccination with RB51 did not reduce B. suis infection rates in maternal or fetal tissues. In conclusion, although B. suis is unlikely to cause abortions and fetal losses in cattle, our data suggest that RB51 vaccination will not protect cattle against B. suis infection after exposure.

AN - 861593532; 19915937 AB - Liver in vitro models are needed to replace animal models for rapid assessment of drug biotransformation and toxicity. The PICM-19 pig liver stem cell line may fulfill this need since these cells have activities associated with xenobiotic phase I and II metabolism lacking in other liver cell lines. The objective of this study was to characterize phase I and II metabolic functions of a PICM-19 derivative cell line, PICM-19H, compared to the tumor-derived human HepG2 C3A cell line and primary cultures of adult porcine hepatocytes. Following exposure of PICM-19H cells to either 3-methylcholanthrene, rifampicin or phenobarbital, the induced activities of cytochrome P450 (CYP450) isozymes CYP-1A, -2, and-3A were assessed. Relative to adult porcine hepatocytes, PICM- 19H cells exhibited 30% and 43%, respectively, of CYP1A and 3A activities, while HepG2 C3A cells exhibited 7% and 0% of those activities. Fluorescent metabolites were extensively conjugated, i.e., 52% and 96% of CYP450-1A and-3A metabolites were released from medium samples following treatment with β-glucuronidase/arylsulfatase. Rifampicin induction of CYP450 isozyme activities was confirmed by conversion of testosterone to 6β-OH-, 2α-OH- and 2β-OH-testosterone, as determined by mass spectrometry. Susceptibility of PICM-19H cells to acetaminophen toxicity was determined; CD50 was calculated to be 14.9±0.9 mM. Toxicity and bioactivation of aflatoxin B1 was determined in 3-methylcholanthrenetreated cultures and untreated controls; CD50 were 1.59 μM and 31 μM, respectively. These results demonstrate the potential use of PICM-19H cells in drug biotransformation and toxicity testing and further support their use in extracorporeal artificial liver device technology.

By improving the profitability of farming, plant breeders improved the economic condition of farmers and contributed to the growth and structure of rural communities. In the years since World War II, agriculture and the quality of rural life have been driven by policies that encouraged and subsidized an agroindustrial production model. Plant breeders responded by developing methods and deploying products attuned to agroindustrial clients. Major achievements by plant breeders of the era include the development of higher-yielding crops suitable to new environments and mechanized harvesting and shipping. As social, technological, and economic changes reinforced the expansion and dominance of the agroindustrial model, rural communities sustained high levels of out-migration. At the same time, a variety of societal and economic forces have encouraged new food system models, including the locavores and community-supported agriculture. Sustainability indices reflect the desire of megaretailers to make the relationship between consumers and the production of their food more transparent. These forces, along with an increased focus on the quality of rural life in America, represent opportunities for plant breeders to address the needs of new clients, to develop methods appropriate to their client's values, and to serve traditional clients in new ways.

We characterized the densities of a soil-borne pathogenic oomycete (Pythium) and a common saprotrophic zygomycete (Mortierella) in nine pairs of forest gaps created by windthrows and adjacent forest understories. We determined the levels of Pythium necessary to cause disease by performing pathogenicity experiments using two Pythium species, a range of Pythium densities, and two common tree species (Acer rubrum and Prunus serotina) from the study sites. Three years post-disturbance, densities of Mortierella remained suppressed in soil from forest gaps compared to levels in intact forest understories while varying across sites and sampling dates. Pythium were infrequently detected likely because of soil handling effects. Expression of disease symptoms increased with increasing inoculum density for seedlings of P. serotina with each Pythium spp. having a similar effect on this species. Conversely, A. rubrum appeared resistant to the two species of Pythium. These results suggest that Pythium densities at sites where they were detected are sufficient to cause disease and possibly affect establishment of susceptible species like P.aaserotina. Because early seral environments have lower loads of the saprotrophic Mortierella, pathogen loads may follow a similar pattern, causing susceptible species to establish more frequently in those habitats than in late-seral forests. Forest disturbances that alter the disease landscape may provide an additional mechanism for explaining succession of temperate forests in addition to the shade-tolerance paradigm.

The objectives of this study were to estimate effective porosity, longitudinal and transverse dispersivity, and first- or zero-order decay coefficients for a field-scale bioreactor with woodchips as the carbon source. In a field-scale bioreactor (6.1m by 6.1m) installed at Decatur, IL nitrate-N concentrations were monitored in 16 monitoring wells installed at 1.5m intervals and 0.75m from each corner. An interpolation method was used for transient, two-dimensional groundwater flow, and the Random Walk Method which does not introduce numerical dispersion errors was used for two-dimensional nitrate-N transport. Nonlinear techniques for fitting the numerical solution to the observed breakthrough curves were used to estimate the transport parameters for the field-scale bioreactor. The longitudinal and transverse dispersivity, the first-order decay coefficient, and the effective porosity were estimated as 10.2cm, 1.13cm, 0.01ha1, and 0.79, respectively. Under a pulse of nitrate-N, high reduction rate of nitrate-N in mass (approximately 47% for 269.9g nitrate-N of the input mass) was observed at the outlet of the field-scale bioreactor at 4.4h of hydraulic retention time. This result suggests that field-scale bioreactors using woodchips as a carbon source may be used to provide significant nutrient reduction from tile-drained fields.

Lake sediment quality at three sites was evaluated in 2004 and 2008 for biological impairment and uptake (animal tissue pesticide residues) from 14 pesticides and three metabolites using Hyalella azteca (Saussure). Eleven pesticides and three metabolites were detected in sediment among the three sites in 2004 and all 17 compounds examined were detected among the three sites in 2008, with the herbicide atrazine having the greatest concentrations. Twenty-eight-day H. azteca survival and growth (mg w/w) indicated no survival effects at any site for either year, but growth impairment occurred in H. azteca exposed to sediment in 2004, whereas growth enhancement occurred in H. azteca exposed to sediments at one site in 2008. Pesticides observed in animal tissue pesticide residues occurred more frequently and in greater concentrations in 2004 compared with 2008. Thirteen pesticides were detected in animal tissue pesticide residues in 2004, with chlorpyrifos occurring in the greatest concentrations, and six pesticides were detected in 2008m, with p,p'-DDT occurring in the greatest concentrations. H. azteca tissue pesticide residues of seven pesticides, two herbicides, three insecticides, one insecticide metabolite, and p,p'-DDT, were associated with growth.

Part of this assessment utilizes stability tests, but these tests can be unreliable due in part to the spatial variability of test results. Conducting more than one test can help to mitigate this uncertainty, though it is unclear how far apart to space tests to optimize our assessments. To address this issue we analyze the probability of sampling two relatively strong test results over 25 spatial datasets collected using a variety of stability tests. Our results show that the optimal distance for spacing stability tests varies by dataset, even when taking the sampling scheme and stability-test type into account. This suggests that no clear rule currently exists for spacing stability tests. Our work further emphasizes the spatial complexity of snow stability measurements, and the need for holistic stability assessments where stability tests are only one part of a multifaceted puzzle.

Hence, the polycross approach has been used to maximize the number of cross combinations that can be represented among progeny. The primary objection to using the polycross approach is the rapid loss of paternity information. Simple sequence repeat (SSR) marker-based paternity analysis is proposed as an effective molecular tool for identifying paternity of progeny from a seven-parent polycross. Using seven highly polymorphic SSR markers, 87 progeny from each polycross family were genotyped along with the parents, producing a total of 51 polymorphic SSR alleles, 15 of which were parent-specific. These alleles enabled the positive identification of the paternity for 79 to 99% of the progeny from the polycross, depending on the maternal parent. The extent to which each parent contributed pollen, and thus was represented as a paternal parent, ranged from 4 to 27%. Winter survival and visual ratings of the polycross progeny in the field were adversely affected by the extent of selfing within each polycross. The ability to identify paternity of polycross progeny with microsatellite markers can be used in sugarcane breeding to maximize the number of desirable crosses from a limited source of flowers with minimal loss of pedigree information.

Host resistance conferred by H genes has been the most effective means to manage Hessian fly populations. More than 32 H genes have been identified in wheat and its relatives. In a previous study, Hessian fly-resistance gene H32 was assigned to the chromosomal bin 3DL3-0.81-1.00, which also harbors H26. The objectives of this study were to develop and validate sequence-tagged site (STS) markers closely linked to H32 and to determine the genetic relationship between H26 and H32. In this study, 11 wheat EST-derived STS markers linked to H26 and three new STS markers were added to the linkage map of H32 using the International Triticeae Mapping Initiative (ITMI) population. Two of the STS markers, Xrwgs10 and Xrwgs12, were found to flank H32 with a genetic distance of 0.5 cM. Another STS marker Xrwgs11, co-segregated with H32. Molecular markers tightly linked to H32 were validated in 12 bread wheat cultivars and an elite breeding line, demonstrating the efficacy of these markers for marker-assisted selection. Comparative mapping analysis indicated that H26 and H32 are either different alleles at the same gene locus or two different, but tightly linked H genes. Ongoing efforts to perform fine mapping and positional cloning of H26 will resolve the relationship between H26 and H32.

Merr.] lines, one containing normal b-amylase [a-1,4-glucan maltohydrolase (EC 3.2.1.2)] activity (Altona Sp sub(1) super(b)) and the other with undetectable b-amylase activity (Altona sp sub(1)) in seeds. SDS-PAGE analysis of 50% isopropanol extracted proteins from soybean seeds revealed a prominent 56 kDa protein. This protein, which was absent in Altona sp sub(1,) was identified as b-amylase by matrix-assisted-laser-desorption-time-of-flight mass spectrometry (MALDI-TOF-MS) and immunoblot analysis using antibodies generated against Arabidopsis b-amylase. Southern blot analysis showed differences in the sizes of the DNA fragments hybridizing to b-amylase probe between the near-isogenic soybean lines. A search of the soybean genome database revealed the presence of nine b-amylase genes in the soybean genome. We have isolated the b-amylase gene (GmBAM 1) by screening a genomic library of wild-type soybean and determined its nucleotide sequence. Analysis of the nucleotide sequence of the GmBAM 1 revealed a complete open reading frame that was interrupted by six introns. In contrast, the GmBAM 1 from Altona sp sub(1) had a 1207 bp deletion near the 5' region that included the second and third exon regions. Our results suggest that this deletion may be responsible for the lack of b-amylase activity in soybean cultivar Altona Altona sp sub(1.)

A popular commercially available assay kit used to detect glucose with a light-sensitive dye reaction was recently discontinued and replaced by a test-tube-scale glucose kit (GAHK-20) that assays glucose through enzymatic coupled reactions and the formation of reduced nicotinamide adenine dinucleotide. The objective of this study was to develop a microplate assay method that uses the GAHK-20 to quantify forage NSC composition. A laboratory microplate enzymatic method was developed for the new glucose kit and evaluated for rapidly assaying NSC components, including glucose, fructose, sucrose, fructan, and starch in 11 species of cool-season perennial grasses. By standard addition, dilution, and temporal tests of enzyme reactions, we found that this microplate enzymatic assay is a rapid and reliable method to quantify NSC composition in grass forage samples. The microplate method allows analysis of many samples per day and considerably improved time and reagent use efficiencies, especially for a large number of samples. In addition to forage, this method should be suitable for measuring NSC concentrations in fresh or dry tissues of a variety of other plant samples.

Only recently have SNP markers been available to researchers in soybean [Glycine max (L.) Merr.] with the release of the third version of the consensus genetic linkage map that added 1141 SNP markers to the map. Our objectives were to add 2500 additional SNP markers to the soybean integrated map and select a set of 1536 SNPs to create a universal linkage panel for high-throughput soybean quantitative trait locus (QTL) mapping. The GoldenGate assay is one high-throughput analysis method capable of genotyping 1536 SNPs in 192 DNA samples over a 3-d period. We designed GoldenGate assays for 3456 SNPs (2956 new plus 500 previously mapped) which were used to screen three recombinant inbred line populations and diverse germplasm. A total of 3000 workable assays were obtained which added about 2500 new SNP markers to create a fourth version of the soybean integrated linkage map. To create a 'Universal Soy Linkage Panela (USLP 1.0) of 1536 SNP loci, SNPs were selected based on even distribution throughout each of the 20 consensus linkage groups and to have a broad range of allele frequencies in diverse germplasm. The 1536 USLP 1.0 will be able to quickly create a comprehensive genetic map in most QTL mapping populations and thus will serve as a useful tool for high-throughput QTL mapping.

U.S. barley breeding programs include six-row and two-row types and winter and spring types in all combinations. To facilitate mapping of complex traits in breeding germplasm, 1816 barley lines from 10 U.S. breeding programs were scored with 1536 single nucleotide polymorphism (SNP) genotyping assays. The number of SNPs segregating within breeding programs varied from 854 to 1398. Model-based analysis of population structure showed the expected clustering by row type and growth habit; however, there was additional structure, some of which corresponded to the breeding programs. The model that fit the data best had seven populations: three two-row spring, two six-row spring, and two six-row winter. Average linkage disequilibrium (LD) within populations decayed over a distance of 20 to 30 cM, but some populations showed long-range LD suggestive of admixture. Genetic distance (allele-sharing) between populations varied from 0.11 (six-row spring vs. six-row spring) to 0.45 (two-row spring vs. six-row spring). Analyses of pairwise LD revealed that the phase of allelic associations was not well correlated between populations, particularly when their allele-sharing distance was >0.2. These results suggest that pooling divergent barley populations for purposes of association mapping may be inadvisable.

The resistance gene is present on a chromosomal translocation derived from Triticum boeoticum Boiss., which has a genome that is partially homologous to the A genome of T. aestivum L. Sr22 has been deployed in a limited number of cultivars due to poor agronomic performance of lines carrying the resistance gene. Linkage analysis of simple sequence repeat (SSR) markers on chromosome 7A was performed to identify loci closely linked to Sr22. The most tightly linked proximal and distal SSR marker loci were Xcfa2123 and Xwmc633, respectively. A two-step process was then used to develop resistant lines having smaller chromosome segments derived from the diploid donor. First, individuals in which a single recombination event had occurred between wheat and the Sr22 introgression were identified in the mapping populations. In spite of reduced recombination between T. boeoticum and T. aestivum chromosomes, sufficient recombination events were found among 398 F sub(3:4) lines derived from recombinant F sub(2) progeny to recover multiple resistant individuals with smaller alien introgressions. Resistant lines were identified having less than 6% of the chromosome arm derived from T. boeoticum. These lines may provide a more agronomically desirable source of Sr22 that can be readily deployed in cultivars resistant to Ug99.

Cultivar releases containing major Hessian fly resistance genes have proven effective in minimizing losses caused by this pest. Nevertheless, the ephemeral nature of major gene resistance necessitates the identification of novel sources of resistance. Hessian fly resistance from Aegilops tauschii Coss. (2n = 2x = 14; genome DD) was introgressed into the genetic background of the soft red winter wheat cultivar Saluda during the development of the germplasm line NC09MDD14. Our genetic characterization and linkage mapping studies showed that resistance to Hessian Fly biotype L in NC09MDD14 was monogenic and the most likely order of the linked microsatellite markers was: Xcfd13- 4.2 cM- Xcfd42- 1.8 cM- Xgdm141- 4.9 cM- Xgdm36- 1.5 cM- NC09MDD14 Hf gene/Xcfd132- 13.4 cM- Xcfd19. This linkage map situated the NCD09MDD14 Hf gene on the short arm of chromosome 6D, within the same deletion bin as the named gene H13. No recombinants between H13 and the NCD09MDD14 Hf gene were found in an allelism study that included 170 F sub(2) individuals from the cross between NCD09MDD14 and Molly (H13). The Hessian fly resistance gene present in the germplasm line NC09MDD14 could be an allele of H13, but unlike H13, the gene in NC09MDD14 provides resistance against biotype vrH13.

Steers were stratified by BW for assignment to six 3.0-ha toxic tall fescue pastures. With or without daily PSBH feeding, treatments were assigned randomly to pastures as the main plot treatment in a split-plot design. Pelleted soybean hulls were group-fed to provide 2.3 kg(steer.d-1) (as fed). With or without SHI (200 mg of progesterone and 20 mg of estradiol) treatments were randomly assigned as the subplot treatment to 2 steer subgroups within each pasture. Sixty-four steers were grazed for 77 d in 2007, and 60 steers were grazed for 86 d in 2008. Pasture forage mass declined linearly over time, but the rate of decline was greater (P = 0.001) in 2007 than in 2008. Pasture forage mass was never below 2,300 kg of DM/ha in either year. Average daily gain for steers on the combined PSBH and SHI treatments was greater (P < 0.01) than for those on the PSBH-only, SHI-only, and control (no SHI, no PSBH) treatments. Average daily gain for the PSBH-only steers was greater (P < 0.01) than for SHI-only and control steers and tended (P = 0.063) to be greater for SHI-only than for control steers. Steroid implants did not affect (P = 0.826) serum prolactin concentrations; however, prolactin concentrations in PSBH steers, with or without SHI, were increased (P = 0.01) 2-fold over SHI-only and control steers. Feeding PSBH and SHI treatments both reduced (P < 0.05) the percentage of steers with rough HCR, and a greater percentage of steers fed PSBH tended (P < 0.076) to have sleek hair coats. An economic analysis was conducted, which determined that costs of additional ADG with PSBH feeding were below breakeven costs over a wide range of PSBH costs and cattle prices. Breakeven costs for PSBH-only treatment for a range of cattle prices of $1.80 to $2.40/kg of BW were less than $120/t, whereas with PSBH feeding combined with SHI the breakeven cost was less than $240/t. Results indicate that steers grazing endophyte-infected tall fescue can be fed PSBH and implanted with steroid hormones to cost effectively increase ADG and that feeding PSBH can increase serum prolactin concentrations and induce some shedding of rough hair coats.

Astragalus lentiginosus Douglas ex Hooker (Fabaceae) is the most taxonomically diverse species in the U. S. flora. To gain insight into the nature of infra-taxa, I ask whether an optimal number of groups exists within A. lentiginosus, whether the varieties represent discrete entities, and whether morphological diversity within A. lentiginosus can be explained by climate. ; METHODS: Morphometric measurement was made on herbarium specimens. Seasonality was inferred by fitting sine waves to climatic data. Statistical clustering, ordination, and multiple regression analyses were employed to test hypotheses. ; Key results: K-means clustering resulted in no clear optimal number of groups within the species. Principal components analysis demonstrated that taxa occupy contiguous regions of morphospace but do not form distinct clusters. Multiple regression demonstrated significant relations among morphology and climatic parameters, which are generally stronger than geographic relations. ; CONCLUSIONS: The bewildering amount of diversity contained within A. lentiginosus begs for decomposition, yet its clinal nature precludes it from division into discrete groups. As a species, A. lentiginosus exists as an array of populations in a delicate balance between homogenizing forces, such as gene flow and retention of ancestral characters, and diversifying forces, such as local adaptation and drift. The effect of these forces has become evident in the phenotype of A. lentiginosus, resulting in more infra-taxa than any other species in the U. S. flora, but has failed to fracture this group into distinct entities.

However, there are no reports on the growth of plasmid-bearing (pYV) virulent Y. pestis in food. The growth of a conditionally virulent pYV-bearing Y. pestis KIM5 in sterile raw ground beef with 7, 15 and 25% fat content was studied at 0, 4, 10 and 25 degree C. The Y. pestis KIM5 did not grow but survived in raw ground beef at 0 and 4 degree C. In raw ground beef with fat contents of 7, 15 and 25% Y. pestis KIM5 replicated at 10 degree C with growth rates of 0.06, 0.05, and 0.06 log sub(10) CFU/h and maximum population densities of 8.65, 8.30, and 8.43 log sub(10) CFU/g, respectively. The growth rate was 4-fold higher and the maximum population density was slightly higher at 25 degree C in raw ground beef at all levels of fat as compared to 10 degree C. Moreover, there was no loss of pYV in surviving Y. pestis KIM5 in raw ground beef stored at refrigerator temperatures or during its growth in raw ground beef. This suggests that raw ground beef contaminated with virulent Y. pestis could cause oro-pharyngeal plague due to refrigeration failure, temperature (10-25 degree C) abuse, and if the meat was not properly cooked. The resultant disease may lead to outbreaks of highly infectious pneumonic plague.

In this field study, we compared six populations of Virginia wildrye originally collected from Maryland and New York with a commercial ecotype and a cultivar ('Omaha') on wet soils at three locations. All entries were transplanted into single-row field plots of 15 plants per plot at Wye, MD, Klingerstown, PA, and Big Flats, NY, in April 2004. Rows were oriented perpendicular to the slope so that each population was evaluated at the top, middle, and bottom slope positions. Survivorship, tillers per plant, and plant dry weight were assessed in 2007. Survivorship after 3 yr ranged from 57 to 76% for the six populations and averaged 85% for the ecotype and 77% for the cultivar. Tillers per plant ranged from 26 to 52 for the populations compared with 32 for the cultivar and 29 for the ecotype. Landscape position affected wildrye plants only at the Maryland site where frequently saturated soils at the bottom slope position reduced survivorship by 50%, tiller number by 60%, and plant dry weight by 82% compared with plants at the top of the slope. Most of the wild populations of Virginia wildrye were similar to the commercial cultivar and ecotype in survival, number of tillers per plant, and biomass indicating that locally adapted native populations can be used directly in conservation plantings.

Candidate genes for regeneration have been identified in multiple species using quantitative trait loci (QTL) and microarray analyses, and some of these genes have been verified as improving regeneration through transformation. Multiple studies have located QTL for regeneration from barley (Hordeum vulgare L.) tissue cultures, but these studies have been based on restriction fragment length polymorphism markers that do not provide information on candidate genes. A recent transcript-derived marker barley map based on expressed sequence tags was used to locate QTL for barley green plant regeneration and identify candidate genes. Quantitative trait loci analysis identified four significant regions, on chromosomes 2H, 3H, 6H, and 7H, in places where QTL were previously identified. An additional four regions were suggestive for green and/or albino plant regeneration on chromosomes 1H, 3H, 4H, and 5H. Examination of transcript-derived markers at the QTL peaks showed that many genes identified as important for regeneration in other species were located in these QTL peaks, including a gene for ferredoxin-nitrate reductase and genes involved in hormone response and synthesis, cell division and the cell cycle, chloroplast development, and transcription factors. Identifying these genes allows manipulation to better understand the processes involved in regeneration from barley tissue cultures.

Puerto Ricans have a disproportionate number of chronic conditions compared with other Hispanic groups. We aimed to characterize fatty acid intake patterns of Puerto Rican adults aged 45-75 y and living in the Greater Boston area (n = 1207) and to examine associations between these patterns and metabolic syndrome. Dietary fatty acids, as a percentage of total fat, were entered into principle components analysis. Spearman correlation coefficients were used to examine associations between fatty acid intake patterns, nutrients, and food groups. Associations with metabolic syndrome were analyzed by using logistic regression and general linear models with quintiles of principal component scores. Four principal components (factors) emerged: factor 1, short- and medium-chain SFA/dairy; factor 2, (n-3) fatty acid/fish; factor 3, very long-chain (VLC) SFA and PUFA/oils; and factor 4, monounsaturated fatty acid/trans fat. The SFA/dairy factor was inversely associated with fasting serum glucose concentrations (P = 0.02) and the VLC SFA/oils factor was negatively related to waist circumference (P = 0.008). However, these associations were no longer significant after additional adjustment for BMI. The (n-3) fatty acid/fish factor was associated with a lower likelihood of metabolic syndrome (Q5 vs. Q1: odds ratio: 0.54, 95% CI: 0.34, 0.86). In summary, principal components analysis of fatty acid intakes revealed 4 dietary fatty acid patterns in this population. Identifying optimal combinations of fatty acids may be beneficial for understanding relationships with health outcomes given their diverse effects on metabolism.

Cows within each BC were randomly assigned to graze either common bermudagrass (CB; n = 3 pastures/yr) or toxic endophyte-infected tall fescue (EI; n = 3 pastures/yr) during a 60-d breeding season. Blood samples were collected at d 0, 30, and 60 of the breeding season, and serum concentrations of prolactin (PRL), IGF-I, and cortisol (CORT) were quantified; PRL and progesterone (P4) also were quantified 10 d before the breeding season (d -10). Body weight and BCS were recorded during the breeding season (d 0, 30, and 60). Cow IMF and RF were measured via ultrasonography at the start and end of the breeding season. Cows with increased (>1 ng/mL) P4 at the beginning of the breeding season (cyclic) had greater (P 0.10) among good- and marginal-BC cows grazing CB, as well as good-BC cows grazing EI; however, marginal-BC cows grazing EI had reduced (P 0.10) among good- (82%) and marginal- (84%) BC cows grazing CB, and good-BC cows grazing EI (79%); however, marginal-BC cows grazing EI had a reduced (P = 0.04) calving rate (61%). Cattle grazing EI during the breeding season lost BC. That reduction in BC may be communicated to the pituitary via hormones that include IGF-I or PRL or both, resulting in decreased calving rates.

We previously detected genetic variation for BCWD resistance in our rainbow trout population, and a family-based selection program to improve resistance was initiated at the National Center for Cool and Cold Water Aquaculture (NCCCWA). This study investigated evidence of major trait loci affecting BCWD resistance using only phenotypic data (without using genetic markers) and Bayesian methods of segregation analysis (BMSA). A total of 10,603 juvenile fish from 101 full-sib families corresponding to 3 generations (2005, 2007, and 2009 hatch years) of the NCCCWA population were challenged by intraperitoneal injection with Flavobacterium psychrophilum, the bacterium that causes BCWD. The results from single- and multiple-QTL models of BMSA suggest that 6 to 10 QTL explaining 83 to 89% of phenotypic variance with either codominant or dominant disease-resistant alleles plus polygenic effects may underlie the genetic architecture of BCWD resistance. This study also highlights the importance of polygenic background effects in the genetic variation of BCWD resistance. The polygenic heritability on the observed scale of survival status Formula is slightly larger than that previously reported for rainbow trout BCWD resistance. These findings provide the basis for designing informative crosses for QTL mapping and carrying out genome scans for QTL affecting BCWD resistance in rainbow trout.

Total parenteral nutrition (TPN) is a major source of infant nutritional support and may influence neonatal metabolic function. Our aim was to test the hypothesis that TPN induces increased adiposity and insulin resistance compared with enteral nutrition (EN) in neonatal pigs. Neonatal pigs were either fed enteral formula orally or i.v. administered a TPN mixture for 17 d; macronutrient intake was similar in both groups. During the 17-d period, we measured body composition by dual-energy X-ray absorptiometry scanning; fasting i.v. glucose tolerance tests (IVGTT) and hyperinsulinemic-euglycemic clamps (CLAMP) were performed to quantify insulin resistance. On d 17, tissue was collected after 1-h, low-dose CLAMP for tissue insulin signaling assays. TPN pigs gained less lean and more body fat and developed hepatic steatosis compared with EN pigs. After 7 and 13 d, IVGTT showed evidence of insulin resistance in the TPN compared with the EN group. Fasting plasma glucose and insulin also were higher in TPN pigs. CLAMP showed that insulin sensitivity was markedly lower in TPN pigs than in EN pigs. TPN also reduced the abundance of the insulin receptor, insulin receptor substrate 1, and phosphatidylinositol 3 kinase in skeletal muscle and liver and the proliferation of total pancreatic cells and beta -cells. Hepatic proinflammatory genes as well as c-Jun-N-terminal kinase 1 phosphorylation, plasma interleukin 6, and tumor necrosis factor- alpha were all higher in TPN pigs than in EN pigs. The results demonstrate that chronic TPN induces a hepatic inflammatory response that is associated with significant insulin resistance, hepatic steatosis, and fat deposition compared with EN in neonatal pigs. Further studies are warranted to establish the mechanism of TPN-induced insulin resistance and hepatic metabolic dysfunction and whether there are persistent metabolic consequences of this lifesaving form of infant nutritional support.

From this work emerged a unified model of the interactions of biotrophic and hemibiotrophic pathogens, which posits that successful pathogens typically defeat two levels of plant defense by translocating cytoplasmic effectors that suppress the first defense (surface arrayed against microbial signatures) while evading the second defense (internally arrayed against effectors). As is predicted from this model and confirmed by sequence pattern-driven discovery of large repertoires of cytoplasmic effectors in the genomes of many pathogens, the coevolution of (hemi)biotrophic pathogens and their hosts has generated pathosystems featuring extreme complexity and apparent robustness. These findings highlight the need for a fourth research era of systems biology in which virulence factors are studied as pathosystem components, and pathosystems are studied for their emergent properties.

Because methyl bromide has provided a reliable return on investment for nematode control, many of these commodities have standardized their production practices based on the use of this chemical and will be negatively impacted if effective and economical alternatives are not identified. Alternative control measures based on other chemicals, genetic resistance, and cultural practices require a greater knowledge of nematode biology to achieve satisfactory results. Here, we provide an overview of nematode management practices that we believe will be relied upon heavily in U.S. high-value crop production systems in a world without methyl bromide. Included are case studies of U.S. high-value crop production systems to demonstrate how nematode management practices other than methyl bromide may be incorporated.

Previously known primarily from Asia and Africa, it was introduced into the Western Hemisphere in 2004. All infected commercial citrus industries continue to decline owing to inadequate current control methods. HLB increase and regional spatial spread, related to vector populations, are rapid compared with other arboreal pathosystems. Disease dynamics result from multiple simultaneous spatial processes, suggesting that psyllid vector transmission is a continuum from local area to very long distance. Evolutionarily, HLB appears to have originated as an insect endosymbiont that has moved into plants. Lack of exposure of citrus to the pathogen prior to approximately 100 years ago did not provide sufficient time for development of resistance. A prolonged incubation period and regional dispersal make eradication nonviable. Multiple asymptomatic infections per symptomatic tree, incomplete systemic distribution within trees, and prolonged incubation period make detection difficult and greatly complicate disease control.

The FA contents in butter fat were very similar to those in milk fat from which butters were produced. The higher average contents of FA in the summer milk compared with the winter milk (P < 0.001) were found for health-beneficial FA, e.g. cis-9, trans-11 conjugated linoleic acid 8.0 mg times g super(-1) vs 4.1 mg times g super(-1), trans vaccenic acid 17.8 mg times g super(-1) vs 8.5 mg times g super(-1), alpha -linolenic acid 6.4 mg times g super(-1) vs 4.4 mg times g super(-1), linoleic acid 20.4 mg times g super(-1) vs 18.4 mg times g super(-1) (P < 0.01), oleic acid 218 mg times g super(-1) vs 194 mg times g super(-1), and for non-atherogenic stearic acid 102 mg times g super(-1) vs 90 mg times g super(-1) of total FA. On the other hand, the contents of health-risky palmitic acid and myristic acid were lower in the summer milk: 293 mg times g super(-1) vs 331 mg times g super(-1) (P < 0.001) and 102 mg times g super(-1) vs 112 mg times g super(-1) FA (P < 0.01), respectively. In comparison to the winter diet, the summer diet improved the rheological and nutritional properties of butter. The summer butter showed lower palmitic/oleic acids content ratio 1.34 compared with 1.71 (P < 0.01) for the winter butter, and improved nutrition value due to quartile reduction of atherogenicity index from 2.72 to 2.19 (P < 0.001).

The study objective was to assess the ability of commercially available enhanced-efficiency N fertilizers to reduce N sub(2)O emissions following their application in comparison with conventional dry granular urea and liquid urea-ammonium nitrate (UAN) fertilizers in an irrigated no-till (NT) corn (Zea mays L.) production system. Four enhanced-efficiency fertilizers were evaluated: two polymer-coated urea products (ESN and Duration III) and two fertilizers containing nitrification and urease inhibitors (SuperU and UAN+AgrotainPlus). Nitrous oxide fluxes were measured during two growing seasons using static, vented chambers and a gas chromatograph analyzer. Enhanced-efficiency fertilizers significantly reduced growing-season N sub(2)O-N emissions in comparison with urea, including UAN. SuperU and UAN+AgrotainPlus had significantly lower N sub(2)O-N emissions than UAN. Compared with urea, SuperU reduced N sub(2)O-N emissions 48%, ESN 34%, Duration III 31%, UAN 27%, and UAN+AgrotainPlus 53% averaged over 2 yr. Compared with UAN, UAN+AgrotainPlus reduced N sub(2)O emissions 35% and SuperU 29% averaged over 2 yr. The N sub(2)O-N loss as a percentage of N applied was 0.3% for urea, with all other N sources having significantly lower losses. Grain production was not reduced by the use of alternative N sources. This work shows that enhanced-efficiency N fertilizers can potentially reduce N sub(2)O-N emissions without affecting yields from irrigated NT corn systems in the semiarid central Great Plains.

The objectives of this study were to estimate the atrazine-mineralizing bacterial population, cumulative atrazine mineralization, atrazine persistence, and metabolite (desethylatrazine [DEA], deisopropylatrazine [DIA], and hydroxyatrazine [HA]) formation and degradation in Colorado and Mississippi s-triazine-adapted and nonadapted soils at three depths (0-5, 5-15, and 15-30 cm). Regardless of depth, the AMBP and cumulative atrazine mineralization was at least 3.8-fold higher in s-triazine-adapted than in nonadapted soils. Atrazine half-life (T sub(1/2)) values pooled over nonadapted soils and depths approximated historic estimates (T sub(1/2) = 60 d). Atrazine persistence in all depths of s-triazine-adapted soils was at least fourfold lower than that of the nonadapted soil. Atrazine metabolite concentrations were lower in s-triazine-adapted than in nonadapted soil by 35 d after incubation regardless of depth. Results indicate that (i) reasonable fate and transport modeling of atrazine will require identifying if soils are adapted to s-triazine herbicides. For example, our data confirm the 60-d T sub(1/2) for atrazine in nonadapted soils, but a default input value of 6 d for atrazine is required for s-triazine adapted soils. (ii) Literature estimates for DEA, DIA, and HA T sub(1/2) values in nonadapted soils are 52, 36, and 60 d, respectively, whereas our analysis indicates that reasonable T sub(1/2) values for s-triazine-adapted soils are 10 d for DEA, 8 d for DIA, and 6 d for HA. (iii) An estimate for the relative distribution of DIA, DEA, and HA produced in nonadapted soils is 18, 72, and 10% of parent, respectively. In s-triazine-adapted soils, the values were 6, 23, and 71% for DIA, DEA, and HA, respectively. The effects of soil adaptation on metabolite distribution need to be confirmed in field experiments.

System models are needed to synthesize these long-term results for making management decisions and for transferring localized data to other conditions. The objectives of this study were to calibrate a cropping systems model (RZWQM2 with the DSSAT v4.0 crop modules) for dryland wheat (Triticum aestivum L.), corn (Zea mays L.), and proso millet (Panicum miliaceum L.) production in the wheat-corn-millet (WCM) rotation from 1995 to 2008, and then to evaluate the model from 1992-2008 for two additional rotations, wheat-fallow (WF) and wheat-corn-fallow (WCF) on a Weld silt loam soil under no-till conditions. Measured biomass and grain yield for the above three rotations were simulated reasonably well with root mean squared errors (RMSEs) ranging between 1147 and 2547 kg ha super(-1) for biomass, and between 280 and 618 kg ha super(-1) for grain yield. Corresponding index of agreement (d) ranged between 0.70 and 0.95 for biomass, and between 0.87 and 0.97 for grain yield. The validated model was further used to evaluate two additional crop rotations: wheat-millet-fallow (WMF) and wheat-corn-millet-fallow (WCMF) (1993-2008) without prior knowledge of the two rotations. We found that the model simulated the mean and range of yield and biomass of the three crops well. These results demonstrated that RZWQM2 can be used to synthesize long-term crop rotation data and to predict crop rotation effects on crop production under the semiarid conditions of eastern Colorado.

However, the role of the cob in soil and water conservation is largely unknown. A rainfall simulator study was conducted in an irrigated corn field in Nebraska having replicated strips where corn residue was removed (6.0 A+/- 1.0 Mg ha super(-1) residue remaining, 49.5% cover) or retained (12.9 A+/- 1.0 Mg ha super(-1) residue remaining, 77% cover). Duplicate plots were installed in each strip and cobs were removed from one and retained in the other. Simulated rainfall was applied for 30 min at a mean rate of 83 mm h super(-1) to plots at antecedent moisture and 24 h later at near saturated soil moisture conditions. Time to initiate runoff, runoff and sediment loss, and water quality parameters were measured. Residue removal reduced the time to initiate runoff (195.9 A+/- 1.0 vs. 239.5 A+/- 4.8 s) and increased sediment loss (0.36 A+/- 0.02 Mg ha super(-1) vs. 0.27 A+/- 0.01 Mg ha super(-1)). Cob removal reduced time to initiate runoff during the antecedent run but not during the saturated run. Residue removal and rainfall treatment (antecedent vs. saturated) affected runoff water quality parameters (NO sub(3)-N concentration, pH, soluble P concentration, and NO sub(3)-N loss). Cob removal did not affect runoff, sediment loss, runoff pH, NO sub(3)-N, NH sub(4)-N, or soluble P loss. Cob removal when adequate stover was retained did not negatively affect erosion and runoff nutrient loss at this site.

Replacing some wheat pasture with perennial cool-season grasses (PCSGs) could reduce uncertainties of sufficient fall forage and annual tillage operations. Wheat forage is capable of producing stocker weight gains >1.4 kg d super(-1), but wheat can accumulate nitrate that poses a health risk to stockers. Levels of crude protein (CP) and nitrate in fall forage clipped 4 yr (2002-2005), from replicated pastures of winter wheat and two PCSG pastures established in 2001 ('Jose' tall wheatgrass [Thinopyrum ponticum (Podp.) Z.-W. Liu & R.-C. Wang], 'Manska' intermediate wheatgrass [Thinopyrum intermedium (Host) Barkworth & D.R. Dewey], and one PCSG pasture established in 2002 ['Lincoln' smooth bromegrass (Bromus inermis Leyss)], were compared. Forage levels of CP in PCSGs were >148 g kg super(-1) dry wt., but were 21 to 37% less than that of wheat (244 A+/- 3 g kg super(-1)). Mean nitrate-N levels of wheat were 400, 1400, 4600, and 840 mg kg super(-1) in 2002 through 2005, respectively. Among the PCSGs, nitrate-N did not exceed 660 mg kg super(-1). The CP levels of PCSGs were often substantially less than that of wheat, but were sufficient for growth of stocker calves. Nitrate risks that sometimes occurred with wheat would make PCSGs a safer choice for pasture.

Merr) is primarily caused by Phomopsis longicolla. Currently, percent seed infection is used as a method for evaluating resistance to PSD. However, researchers need a common system for classifying soybean genotypes for their reaction to P.longicolla that is consistent across environments. The purpose of this research was: (i) to evaluate the reaction of a select set of soybean accessions to P. longicolla, and (ii) determine the effects of irrigation and two harvest regimes (normal and delayed) on seed infection. We propose a classification system for comparing reactions to P. longicolla among accessions based on a Phomopsis seed infection index (PSII), derived by dividing the percent seed infection of each accession by percent seed infection values of susceptible standards selected within early and late maturity groups. Percent seed infection by P. longicolla infection was greater when accessions were irrigated during the growing season and harvested at normal maturity. Some lines such as MO/PSD-0259 were rated as resistant to P. longicolla (7% seed infection) when not irrigated and harvested at maturity, but were rated as susceptible (39% seed infection) with irrigation and delayed harvest. The resistance ratings to P. longicolla using percent seed infection and PSII varied among accessions. SS93-6012, for example, had similar ratings for both (9% seed infection and 16% PSII). PI 416942 exhibited some resistance to P. longicolla based on percent seed infection (8%), but no resistance based on PSII (32%). Accessions PI 594478, Delmar, SS93-6012, SS93-6181, PI 594603A, and PI 594712 were classified by PSII as moderately resistant under irrigation and with delayed harvest. These results indicate that simple comparisons of percent seed infection among accessions without irrigation, without delayed harvest, and without a standard control of a similar maturity group might result in false conclusions about resistance to P. longicolla.

Thus maize leaves often operate at lower transpiration efficiency (TE) than potentially achievable for species with C sub(4) metabolism. I tested whether several maize lines described as drought resistant or drought tolerant operated with higher leaf te than less drought-adapted lines. Field measurements of leaf te were conducted over two seasons for five reputedly drought-resistant lines of maize and three locally grown lines not regarded as drought resistant. Midday photosynthesis, transpiration, stomatal conductance, and substomatal carbon dioxide concentration measurements were made under the ambient field conditions of air temperature and humidity in Beltsville, MD. Soil moisture was not limiting. Consistent and significant differences among the lines occurred for stomatal conductance, substomatal carbon dioxide concentration, and TE, but no significant differences among the lines occurred in photosynthesis. One drought-tolerant line had higher te than all others tested, and one of the local lines had the lowest TE, but the drought-tolerant lines as a group did not have significantly higher TE. It is concluded that significant genotypic variation in leaf te exists in maize, and that te could be improved without reducing photosynthesis.

Because this RIL population had been previously used to map QTLs for three other diseases, present use of this population allowed direct comparison between the various disease resistance QTLs. Multiple interval mapping using QTL Cartographer v2.5 putatively identified 12 BPB QTLs, three of which were statistically significant in both years and found to have epistatic effects in 2002. TeQing was the source of resistance for eight QTLs; Lemont for four. Four BPB QTLs colocated with QTLs previously identified as providing resistance to one or multiple other diseases. Three BPB QTLs were also associated with late flowering. Because late flowering panicles are subjected to cooler temperatures that are less conducive to disease development during grain fill, it is possible that the genetic effects of the heading-related QTLs were biased. The present data could not distinguish between pleiotropy and close linkage of the BPB QTLs with the previously identified heading and disease resistance QTLs.

Because some late season drought stress is avoided, early planting might also work for dryland production. Objectives were to compare the performance of early and normal planted cotton while grown under both irrigated and dryland conditions. Six cotton cultivars were planted in the field at Stoneville, MS during either the first week of April (Early) or the first week of May (Normal) in 2005 to 2008. Half the plots were irrigated and half were dryland. Dry matter partitioning, light interception, flowering, lint yield, yield components, and fiber quality data were collected. With the exception of the hurricane-plagued season of 2005, irrigation increased lint yield regardless of planting date. In 2006 and 2007, early planting increased lint yield by 13% under irrigated conditions, but not dryland conditions. Early planting decreased dryland lint yield by 35% in 2008 but not under irrigated conditions. Fiber from normal planted cotton was 5% stronger than from those early planted. Both early planting and dryland conditions had a propensity to increase the short fiber content. Based on the 4 yr of this research, early planting appears to need irrigation to achieve its yield benefits, which implies that dryland Mississippi Delta cotton producers should not adopt an early planting production strategy.

Dry acids are commonly used to reduce ammonia emissions from poultry houses; however, little is known about how acidification affects the litter biologically. The goal of this laboratory incubation was to compare the microbiological and physiochemical effects of dry acid amendments (Al+Clear, Poultry Litter Treatment, Poultry Guard) on poultry litter to an untreated control litter and to specifically correlate uric acid and urea contents of these litters to the microbes responsible for their mineralization. Although all three acidifiers eventually produced similar effects within the litter, there was at least a 2-wk delay in the microbiological responses using Poultry Litter Treatment. Acidification of the poultry litter resulted in >3 log increases in total fungal concentrations, with both uricolytic (uric acid degrading) and ureolytic (urea degrading) fungi increasing by >2 logs within the first 2 to 4 wk of the incubation. Conversely, total, uricolytic, and ureolytic bacterial populations all significantly declined during this same time period. While uric acid and urea mineralization occurred within the first 2 wk in the untreated control litter, acidification resulted in delayed mineralization events for both uric acid and urea (2 and 4 wk delay, respectively) once fungal cell concentrations exceeded a threshold level. Therefore, fungi, and especially uricolytic fungi, appear to have a vital role in the mineralization of organic N in low-pH, high-N environments, and the activity of these fungi should be considered in best management practices to reduce ammonia volatilization from acidified poultry litter.

Storm event sampling, which is vital for adequate assessment of water quality in small (wadeable) streams, is typically conducted by manual grab or integrated sampling or with an automated sampler. Although it is typically assumed that samples from a single point adequately represent mean cross-sectional concentrations, especially for dissolved constituents, this assumption of well-mixed conditions has received limited evaluation. Similarly, the impact of temporal (within-storm) concentration variability is rarely considered. Therefore, this study evaluated differences in stormwater quality measured in small streams with several common sampling techniques, which in essence evaluated within-channel and within-storm concentration variability. Constituent concentrations from manual grab samples and from integrated samples were compared for 31 events, then concentrations were also compared for seven events with automated sample collection. Comparison of sampling techniques indicated varying degrees of concentration variability within channel cross sections for both dissolved and particulate constituents, which is contrary to common assumptions of substantial variability in particulate concentrations and of minimal variability in dissolved concentrations. Results also indicated the potential for substantial within-storm (temporal) concentration variability for both dissolved and particulate constituents. Thus, failing to account for potential cross-sectional and temporal concentration variability in stormwater monitoring projects can introduce additional uncertainty in measured water quality data.

Dietary provitamin A carotenoids can be converted into vitamin A mainly by carotenoid 15,15'-monooxygenase 1 (CMO1) and, to a lesser degree, carotenoid 9'10'-monooxygenase 2 (CMO2). CMO1 has been shown to be regulated by several transcription factors, such as the PPAR, retinoid X receptor, and thyroid receptor (TR). The regulation of CMO2 has yet to be identified. The impact of chronic alcohol intake on hepatic expressions of CMO1 and CMO2 and their related transcription factors are unknown. In this study, Fischer 344 rats were pair-fed either a liquid ethanol Lieber-DeCarli diet (n = 10) or a control diet (n = 10) for 11 wk. Hepatic retinoid concentration and expressions of CMO1, CMO2, PPARg, PPARa, and TRb as well as plasma thyroid hormones levels were analyzed. We observed that administering alcohol decreased hepatic retinoid levels but increased mRNA concentrations of CMO1, CMO2, PPARg, PPARa, and TRb and upregulated protein levels of CMO2, PPARg, and PPARa. There was a positive correlation of PPARg with CMO1 (r = 0.89; P < 0.0001) and both PPARg and PPARa with CMO2 (r = 0.72, P < 0.001 and r = 0.62, P < 0.01, respectively). Plasma thyroid hormone concentrations did not differ between the control rats and alcohol-fed rats. This study suggests that chronic alcohol intake significantly upregulates hepatic expression of CMO1 and, to a much lesser extent, CMO2. This process may be due to alcohol-induced PPARg expression and lower vitamin A status in the liver.

Public health implications of water chemistry and aquatic insects within channelized and unchannelized headwater streams have not been explored. We sampled water chemistry and aquatic insects in two channelized and two unchannelized headwater streams in central Ohio from December 2005 until November 2008. Maximum concentrations of ammonium, nitrate plus nitrite, and chlorothalonil were greater in channelized streams. Nitrate plus nitrite and atrazine also exceeded drinking water standards more often in channelized streams. Maximum concentrations of simazine and the percentage of times it exceeded the drinking water standards were greater in unchannelized streams. The predicted hazard potential of nutrient and pesticide mixtures was greater in channelized streams. Mosquito abundance did not differ between stream types. Chironomid abundance was greater in channelized streams. Biting dipterans did not exhibit consistent abundance trends and only differed between stream types in the summer and fall. Our results suggest that if whole stream uptake of nutrients and pesticides is minimal in channelized headwater streams then nutrient and pesticide inputs from these streams may impact downstream drinking water sources. Our results also suggest channelized and unchannelized headwater streams are not serving as a significant source of mosquitoes.

Cd and Se accumulation in plant organs has also been estimated. The studied compounds applied at 12, 24 and 60 mu mol L super(-1) reduced dry mass of plant organs, water content as well as chlorophyll content in the leaves, whereby toxic effects increased with increasing compound concentrations. The lowest toxicity exhibited CdSeO sub(4), and those of CdSeO sub(3) and Cd(NCSe) sub(2)(nia) sub(2) were comparable. Cd(NCS) sub(2)(nia) sub(2) was less toxic than Cd(NCSe) sub(2)(nia) sub(2). Bioaccumulation factors (BAFs) related to Cd accumulation in roots were higher than the corresponding BAFs determined for shoots. The highest values of BAF in both plant organs were determined for CdSeO sub(4), and the lowest ones for CdSeO sub(3). In CdSeO sub(4)-treatment, the portion of Cd allocated in shoots related to the total Cd amount accumulated by the plant exceeded 50%. On the other hand, application of CdSeO sub(4) caused that > 90% of Se was allocated in the shoots, but with CdSeO sub(3) and Cd(NCSe) sub(2)(nia) sub(2) treatments, shoot Se contents achieved only 26.7-30.9% and 37.1-53.2% from the total selenium amount accumulated by plants.

We converted an absolute quantification assay of Puccinia coronata DNA to a relative assay by adding a TaqMan+ primers/probe set specific to the oat b-actin gene to simplify and improve quantification of fungal infection. The new multiplex assay estimates the amount of fungal DNA in a sample relative to the amount of host DNA and requires fewer and less labour-intensive steps than previous assays. The relative fungal DNA assay (RFDNA) reliably detected and quantified both host and pathogen DNA over five orders of magnitude and was at least as sensitive as either digital image analysis (DLA) or absolute estimation of fungal DNA (AFDNA) in repeated greenhouse studies using 12 oat cultivars with different resistance responses to P. coronata isolate LGCG. Measuring crown rust resistance to LGCG using DLA, AFDNA and RFDNA in a P8669/P94163 recombinant inbred line population produced segregation ratios that did not differ from the 1:1 Mendelian ratio expected for a single gene. Compared to the AFDNA assessment method, the RFDNA assay is equally sensitive, yet faster and much easier to use than the AFDNA method for precise quantification of the crown rust pathogen in oat leaves. The method will be especially useful for streamlining measurement of partial resistance, since uncovering small differences in resistance requires phenotypic evaluation of large populations.

AN - 754904355; 13553237 AB - Stagonospora nodorum blotch (SNB) has long been a problem in wheat production areas by affecting both the leaves and glumes of susceptible bread and durum wheat. Resistance to both disease phases has been shown to be complexly inherited and although much effort has gone into the identification and introgression of disease resistance, less than satisfactory progress has been made in producing SNB resistant cultivars. A major pitfall in this process has been the lack of understanding of the underlying mechanism of disease resistance. Recently, we have shown the Stagonospora nodorum-wheat interaction to involve multiple effector proteins also known as host-selective toxins (HSTs) that interact either directly or indirectly with dominant wheat sensitivity/susceptibility gene products to induce disease. Therefore, we have referred to this system as an 'inverse gene-for-gene' interaction (i.e. effector-triggered susceptibility) because the recognition of an effector protein by the host leads to susceptibility rather than resistance as it does in classical gene-for-gene interactions currently referred to as effector-triggered immunity. To date, we have reported five HST-host gene interactions. In each case, toxin sensitivity and susceptibility is controlled by a single dominant gene and in all but one case the interaction is dependent on light. Using quantitative trait loci analysis, the toxin-host gene interactions have been shown to account for 18-95% of the disease variation, highlighting the importance of these interactions. Several unpublished interactions also exist making this a model system for the investigation of the molecular mechanism of necrotrophic disease.

Outbreaks of E. coli O157:H7 disease are often associated with undercooked beef, but there are other sources of transmission, including water, produce, and animal contact, which can often be linked directly or indirectly to cattle. Thus, preharvest control of this pathogen in cattle production should have a large impact on reducing the risk of human foodborne illness. In this review, we will summarize preharvest research on E. coli O157:H7 in cattle and the production environment, focusing on factors that may influence the transmission, prevalence, and levels of this pathogen, such as season, diet, high-level shedders, and animal stress. In addition, we will discuss recent research on the reduction of this pathogen in cattle production, including vaccination, probiotics, bacteriophage, and manure treatments.

ODM containing octadecylammonium at 100% of the ion-exchange capacity of montmorillonite exhibited a high efficiency of eradication of L. innocua from water suspensions during a contact time of 10 min, with I sub(50) = 0.03 mg; ml super(-1) at a bacterial suspension density of 10 super(4) CFU; ml super(-1), and I sub(50) < 0.01 mg; ml super(-1) at a bacterial suspension density of 10 super(3) CFU; ml super(-1). The compound was effective also at devitalization of L. innocua in water suspensions during a contact time of 12 h, with minimum inhibitory concentration of 0.1 mg; ml super(-1) at a bacterial suspension density of 10 super(7) CFU; ml super(-1). Montmorillonite modified with octadecylammonium at 20% of the ion-exchange capacity exhibited an efficiency of eradication of L. innocua from water suspensions during a contact time of 10 min at I sub(50) of 3 mg; ml super(-1). Because this compound sediments in water, it may be a candidate for further study at microbiological decontamination of water in food processing environments.

We conducted an experiment from 2002 through 2006 comparing yield, quality, and water and N use of durum and three annual forages, barley (Hordeum vulgare L.), barley interseeded with pea [Pisum sativum L. ssp. arvense (L.) Poir.], and foxtail millet [Setaria italica (L.) Beauv.] in 2-yr rotations. Durum in rotation with summer fallow and alfalfa (Medicago sativa L.) were included. Averaged over 5 yr, alfalfa had higher forage yield and quality, water use, and N accumulation compared to annual forages. Annual forages had similar preplant and postharvest soil water contents, but barley and barley-pea had higher yields and water use compared to millet. Barley-pea intercrop had superior forage crude protein (CP), neutral detergent fiber (NDF) and N accumulation compared to barley and millet, but acid detergent fiber (ADF) and nitrogen recovery index (NRI) were similar among annual forages. Averaged over 4 yr, preplant soil water and residual N content were greater for durum following fallow than for durum following annual forages, resulting in reduced fertilizer N requirement and greater yield, water use, grain N accumulation and NRI following fallow. Replacing summer fallow with annual forages reduced durum grain yield by 727 kg ha super(-1) but provided forage yield of 4.9 Mg ha super(-1). Annualized net returns in annual forage-durum systems were $127 ha super(-1), $77 and $34 ha super(-1) greater than for fallow-durum and alfalfa, respectively. Replacing summer fallow with annual forages reduced durum yield but improved profitability.

This nonirrigated field study was conducted from 1997 through 2002, which coincided with the 1998-2002 drought that affected most of the United States. The objective was to determine the effect of rotation and tillage on cotton (Gossypium hirsutum L.) productivity. Treatments in the study were rotation [cotton rotated with corn (Zea mays L.), cotton planted after a rye (Secale cereale L.) winter cover crop, and continuous cotton with no cover crop] and tillage system (conventional tillage and conservation tillage). Two levels of aldicarb [2-methyl-2-(methylthio)propanal O- oxime] (0 and 1.18 kg a.i. ha super(-1)) were also included because of known soil management effects on thrips (Frankliniella sp.) and root-knot nematodes (Meloidigyne incognita). The predominant soil types were Bonneau loamy sand (loamy, siliceous, subactive, thermic Arenic Paleudult) and Norfolk loamy sand (fine-loamy, kaolinitic, thermic Typic Kandiudult). Rotation did not affect cotton yield in any year. Tillage did not affect cotton yield in 1997. Conservation tillage resulted in an average 25% yield increase in cotton lint yield over conventional tillage during the 5-yr drought. Tillage and aldicarb affected both thrips and root-knot nematodes, but lack of interaction among these factors for lint yield suggested that management of these pests was not the predominant cause for the cotton yield increase with conservation tillage. Conservation tillage for cotton production could be an important method to help mitigate the effects of climate change in the region if change occurs as predicted.

Moench] and other cereals in Mediterranean and semiarid tropical climates. Current methodologies for identifying the nonsenescent (stay-green) trait require the right intensity of drought stress at the right developmental stage to visually evaluate lines in the field. Field-based evaluations of drought tolerance are notoriously difficult to manage, and often require growing lines in multiple locations across several years to acquire a meaningful assessment of the stay-green trait. By means of a 30-min high-temperature challenge to leaf tissue during flowering of well-watered sorghum and a 30-min room temperature recovery, we show that stay-green lines can be readily identified. Using chlorophyll fluorescence to monitor tissue injury, we found that tissue with higher intercellular sucrose concentrations exhibited higher chlorophyll fluorescence yield following the temperature challenge. Stay-green lines evaluated in this study maintained higher dawn leaf sucrose levels than the senescent lines among the five youngest leaf positions. Evaluation of 10 known stay-green and senescent sorghum lines, previously reported in the literature, with this bioassay allowed us to separate the two classes of sorghum from well-watered flowering plants. The stay-green lines can also be separated from senescent lines under well-watered greenhouse conditions from the boot stage onward. This technology will greatly reduce the selection time needed to identify drought tolerant sorghum.

These waters were previously classified, without verification, as dangerous and it is now necessary to question the justice of the present classification under the new legislation for waste management (Waste Law No. 223/2001) in the Slovak Republic. Methods: Young seedling of the dicotyledon terrestrial plant mustard Sinapis alba L. were used for determination of the dry and fresh root and shoot biomass and photosynthetic pigment production. Observed parameters were evaluated in laboratory experiments with three types of washing waste-waters from a cutlery production line. All contamination of tested washing waste-waters came from heavy metals (Ni, Cr), non-polar extractable compounds (NEC; residues of oils and waxes from polishing of stainless steel cutlery) and detergents (used for cutlery degreasing). Photosynthetic pigments (chlorophyll a, b, and total carotenoids) were extracted in 96% ethanol and measured spectrophotometrically at 665, 649, and 470nm. All phytotoxicity tests were carried out in triplicate, and they included a control in tap water. Results: All tested washing waters reduced root dry mass, whereas the shoot dry mass was either unaffected or it increased. The tested washing waters' effect was stronger on fresh mass production than on dry mass production. This indicated problems in water reception and translocation. The adverse effect on photosynthetic pigments production increased only slowly with remaining washing waste-water concentration. Almost all Chl a/b ratios were the same as for the control and this indicated no significant differences in the reduction of either a or b chlorophylls. As opposed to chlorophylls, carotenoids content increased in the presence of tested washing waste-waters and equaled or exceeded their content in the control. As the ratio of Chl(a+b)/Car was lower than that for the control for almost all tested samples, a stronger reduction in chlorophylls than in carotenoids was confirmed. Discussion: The phytotoxicity of waste-waters from cutlery production line washing reservoirs was evaluated and the effects on dry and fresh mass production and photosynthetic pigments amount was discussed as Cr and Ni toxicity. Conclusions: It is concluded from the present study that washing waste-waters from cutlery production line are quite toxic to plants, thus reducing biomass and photosynthetic pigment production and influencing water translocation through the plant. Recommendations and perspectives: These determined adverse effects of washing waste-waters from this cutlery production line classified them as too dangerous to be spread on open-land soil. On the basis of this study, high toxicity of the presented waste-waters from metal surface-finishing as well as justness of their liquidation as hazardous wastes by legally assigned persons were recommended.

We evaluated the effects of tillage and cropping sequence combinations and N fertilization on dryland crop biomass (stems + leaves) and soil surface CO sub(2) flux and C content (0- to 120-cm depth) in a Williams loam from May to October, 2006 to 2008, in eastern Montana. Treatments were no-tilled continuous malt barley (Hordeum vulgaris L.) (NTCB), no-tilled malt barley-pea (Pisum sativum L.) (NTB- P), no-tilled malt barley-fallow (NTB-F), and conventional-tilled malt barley-fallow (CTB-F), each with 0 and 80 kg N ha super(-1). Measurements were made both in Phase I (malt barley in NTCB, pea in NTB-P, and fallow in NTB-F and CTB-F) and Phase II (malt barley in all sequences) of each cropping sequence in every year. Crop biomass varied among years, was greater in the barley than in the pea phase of the NTB-P treatment, and greater in NTCB and NTB-P than in NTB-F and CTB-F in 2 out of 3 yr. Similarly, biomass was greater with 80 than with 0 kg N ha super(-1) in 1 out of 3 yr. Soil CO sub(2) flux increased from 8 mg C m super(-2) h super(-1) in early May to 239 mg C m super(-2) h super(- 1) in mid-June as temperature increased and then declined to 3 mg C m super(-2) h super(-1) in September-October. Fluxes peaked immediately following substantial precipitation (>10 mm), especially in NTCB and NTB-P. Cumulative CO sub(2) flux from May to October was greater in 2006 and 2007 than in 2008, greater in cropping than in fallow phases, and greater in NTCB than in NTB-F. Tillage did not influence crop biomass and CO sub(2) flux but N fertilization had a variable effect on the flux in 2008. Similarly, soil total C content was not influenced by treatments. Annual cropping increased CO sub(2) flux compared with crop-fallow probably by increasing crop residue returns to soils and root and rhizosphere respiration. Inclusion of peas in the rotation with malt barley in the no-till system, which have been known to reduce N fertilization rates and sustain malt barley yields, resulted in a CO sub(2) flux similar to that in the CTB-F sequence.

Shortly after its discovery, surveys were conducted, based on the visual inspection of trees. The shortcomings of visual surveys have led to a critical research need to find an efficient survey method for detecting A. planipennis infestations. Here, we present a review of research that has led to the development of effective trapping methods for A. planipennis. Studies on the insect's biology and behavior have led to the identification of several potential attractants as well as the design of a visually attractive trap. The ongoing challenge in developing an optimally efficient trapping methodology for A. planipennis will involve finding the best combination of variables, such as trap shape, trap color (or other visual properties), trap placement, lure components, as well as the ratios and release rates of those components.

In most cases, eutrophication has accelerated by increased inputs of phosphorus due to intensification of crop and animal production systems since the early 1990s. Despite substantial measurements using both laboratory and field techniques, little is known about the spatial and temporal variability of phosphorus dynamics across landscapes, especially in agricultural landscapes with cow-calf operations. Critical to determining environmental balance and accountability is an understanding of phosphorus excreted by animals, phosphorus removal by plants, acceptable losses of phosphorus within the manure management and crop production systems into soil and waters, and export of phosphorus off-farm. Further research effort on optimizing forage-based cow-calf operations to improve pasture sustainability and protect water quality is therefore warranted. We hypothesized that properly managed cow-calf operations in subtropical agroecosystem would not be major contributors to excess loads of phosphorus in surface and ground water. To verify our hypothesis, we examined the comparative concentrations of total phosphorus among soils, forage, surface water, and groundwater beneath bahiagrass-based pastures with cow-calf operations in central Florida, USA. Materials and methods: Soil samples were collected at 0-20; 20-40, 40-60, and 60-100cm across the landscape (top slope, middle slope, and bottom slope) of 8ha pasture in the fall and spring of 2004 to 2006. Forage availability and phosphorus uptake of bahiagrass were also measured from the top slope, middle slope, and bottom slope. Bi-weekly (2004-2006) groundwater and surface water samples were taken from wells located at top slope, middle slope, and bottom slope, and from the runoff/seepage area. Concentrations of phosphorus in soils, forage, surface water, and shallow groundwater beneath a bahiagrass-based pasture and forage availability at four different landscape positions and soil depth (for soil samples only) in 2004, 2005, and 2006 were analyzed statistically following a two-way analysis of variance using the SAS PROC general linear models model. Where the F-test indicated a significant (p,0.05) effect, means were separated following the method of Duncan multiple range test using the appropriate error mean squares. Results and discussion: Concentrations of soil total phosphorus and degree of phosphorus saturation varied significantly (p,0.001) with landscape position and sampling depth, but there was no interaction effect of landscape position and sampling depth. Overall, there was slight buildup of soil total phosphorus. There was no movement of total phosphorus into the soil pedon since average degree of phosphorus saturation in the upper 20cm was 21% while degree of phosphorus saturation at 60-100cm was about 3%. Our livestock operations contributed negligible concentrations of phosphorus to groundwater (0.67mgL super(-1)) and surface water (0.55mgL super(-1)). The greatest forage mass of 6,842kgha super(-1) and the greatest phosphorus uptake of 20.4kgPha super(-1) were observed at the top slope in 2005. Both forage availability and phosphorus uptake of bahiagrass at the bottom slope were consistently the lowest when averaged across landscape position and years. These results can be attributed to the grazing patterns as animals tend to graze more and leave more excretions at the bottom slope. This behavior may lead to an increase in the concentration of soil phosphorus. Effective use and cycling of phosphorus is critical for pasture productivity and environmental stability. Phosphorus cycling in pastures is complex and interrelated, and pasture management practices can influence the interactions and transformations occurring within the phosphorus cycle. Conclusions: Our results indicate that current pasture management systems which include cattle rotation in terms of grazing days and current fertilizer application (inorganic+manures+urine) for bahiagrass pastures in subtropical climates on loamy sand soils offer little potential for negatively impacting the environment. Properly managed livestock operations contribute negligible loads of phosphorus to shallow groundwater and surface water. Overall, there was no buildup of soil total phosphorus in bahiagrass-based pasture. Therefore, results of this study may help to renew the focus on improving inorganic fertilizer efficiency in subtropical beef cattle systems and maintaining a balance of phosphorus removed to phosphorus added to ensure healthy forage growth and minimize phosphorus runoff. Recommendations and perspectives: Research on the pathways and rates of movement of phosphorus deposited in urine and dung through various pools and back to the plants will be the focal point of our future investigations. Further studies are needed to determine whether the environmental and ecological implications of grazing and haying in forage-based pastures are satisfied over the longer term. New knowledge based on the whole-farm approach is desirable to identify pastureland at risk of degradation and to prescribe treatments or management practices needed to protect the natural resources while maintaining an economically and environmentally viable operation.

In the fall of 1997, a study was initiated to compare the response of two crop management systems (conventional tillage and no-tillage) to elevated CO sub(2). The study used a split-plot design replicated three times with two management systems as main plots and two atmospheric CO sub(2) levels (ambient and twice ambient) as split plots using open-top chambers on a Decatur silt loam soil (clayey, kaolinitic, thermic Rhodic Paleudults). The conventional system was a grain sorghum [Sorghum bicolor (L.) Moench.] and soybean [Glycine max (L.) Merr.] rotation with winter fallow and spring tillage practices. In the no- tillage system, sorghum and soybean were rotated, and three cover crops were used [crimson clover (Trifolium incarnatum L.), sunn hemp (Crotalaria juncea L.), and wheat (Triticum aestivum L.)]. Over multiple growing seasons, the effect of management and CO sub(2) concentration on leaf-level gas exchange during row crop (soybean in 1999, 2001, and 2003; sorghum in 2000, 2002, and 2004) reproductive growth were evaluated. Treatment effects were fairly consistent across years. In general, higher photosynthetic rates were observed under CO sub(2) enrichment (more so with soybean) regardless of residue management practice. Elevated CO sub(2) led to decreases in stomatal conductance and transpiration, which resulted in increased water use efficiency. The effects of management system on gas exchange measurements were infrequently significant, as were interactions of CO sub(2) and management. These results suggest that better soil moisture conservation and high rates of photosynthesis can occur in both tillage systems in CO sub(2)- enriched environments during reproductive growth.

Germplasm Collection AN - 746049894; 12590676 AB - Cacao (Theobroma cacao L.) is an important cash crop in many tropical countries. Cacao accessions must be propagated vegetatively to conserve genetic integrity due to its allogamous nature and its seed recalcitrance (lack of dormancy). Therefore, cacao germplasm is usually maintained as living trees in field collections and has resulted in varying rates of misidentification and duplication. Using a high throughput genotyping system with 15 microsatellite loci, all 924 trees in the USDA-ARS Mayaguez cacao collection were fingerprinted. Nineteen accessions (12.3%) were found to have intraplant errors while 14 (9.1%) synonymous sets were identified that included replicates of 49 accessions. The average number of alleles (8.8; SE = 0.56) and gene diversity (H sub(Obs) = 0.65; SE = 0.026) indicate a high allelic diversity in this collection. A distance-based cluster analysis and a Bayesian assignment test showed that the cacao accessions can be classified into four distinct clusters, with their geographical origins covering most of the cacao growing regions in the Americas. Assessment of the representative diversity of the collection led to the identification of several genetic gaps, including underrepresented genetic populations and particular traits of economic and agronomic value. The improved understanding of identities and structure in the USDA-ARS cacao collection will contribute to more efficient use of cacao in conservation and breeding.

Among the proposals for acquiring this feedstock, without impacting other land uses such as food or forage, is the use of up to 50% of Conservation Reserve Program (CRP) land. Our objective was to determine CRP biomass production in northwestern Oklahoma and record the harvest impact on plant species composition, plant growth, and soil characteristics. Six CRP sites were harvested on three dates, early August, early October, and postfrost, for three consecutive years, 2004, 2005, and 2006. Three sites were Old World bluestem (OWB; Bothriochloa spp.) and three sites were native mixed species (NM). Across all years and harvest dates OWB produced 3790 kg ha super(-1) and NM produced 1920 kg ha super(-1) of dry biomass. Maximum yields were obtained at the October harvest for both OWB (4170 kg ha super(-1)) and NM (2180 kg ha super(-1)). There was no observed change in species composition or soil characteristics. Among all species evaluated, nitrogen, neutral detergent fiber, carbon, and ash concentrations varied significantly. Within NM, production of dry biomass among native grass species differed and ranged from 213 g plant super(-1) for big bluestem (Andropogon gerardii Vitman) to 14 g plant super(-1) for sand lovegrass [Eragrostis trichodes (Nutt.) Alph. Wood]. Biomass production consistently declined at all sites and for all harvest dates over the three harvest years, but the greatest decline in yield was for OWB.

Assays involve membrane overlays of overnight colonies on nonselective agar plates to detect b-glucuronidase and lysyl aminopeptidase activities for E. coli and Vibrionaceae, respectively. Cellulose membranes containing the substrates 4-methylumbeferyl-b-D-glucuronide (MUG) produced a bright blue fluorescence when overlaid onto E. coli, while L-lysyl-7-amino-4-trifluoromethylcoumarin produced green fluorescent foci when overlaid onto Vibrionaceae family members. A multiplex assay was also developed for simultaneously enumerating total E. coli and total Vibrionaceae in oysters and seawater. Overall, 65% of overlaid E. coli (non-O157:H7) were MUG-positive, compared with 62% as determined by the most-probable-number-MUG assay. The overlays are rapid, simple, and cost effective for quantification purposes. This research provides practical alternatives for monitoring bacterial indicators and potential pathogens in complex samples, including molluscan shellfish.

High islands are subjected to constant erosion over geologic time, which establishes an important source of terrigeneous sediment for nearby marine communities. Many of these sediments are deposited in mangrove forests and offer mangroves a potentially important means for adjusting surface elevation with rising sea level. In this study, we investigated sedimentation and elevation dynamics of mangrove forests in three hydrogeomorphic settings on the islands of Kosrae and Pohnpei, Federated States of Micronesia (FSM). Surface accretion rates ranged from 2.9 to 20.8mmy super(-1), and are high for naturally occurring mangroves. Although mangrove forests in Micronesian high islands appear to have a strong capacity to offset elevation losses by way of sedimentation, elevation change over 6[frac12] years ranged from -3.2 to 4.1mmy super(-1), depending on the location. Mangrove surface elevation change also varied by hydrogeomorphic setting and river, and suggested differential, and not uniformly bleak, susceptibilities among Pacific high island mangroves to sea-level rise. Fringe, riverine, and interior settings registered elevation changes of -1.30, 0.46, and 1.56mmy super(-1), respectively, with the greatest elevation deficit (-3.2mmy super(-1) ) from a fringe zone on Pohnpei and the highest rate of elevation gain (4.1mmy super(-1)) from an interior zone on Kosrae. Relative to sea-level rise estimates for FSM (0.8-1.8mmy super(-1)) and assuming a consistent linear trend in these estimates, soil elevations in mangroves on Kosrae and Pohnpei are experiencing between an annual deficit of 4.95mm and an annual surplus of 3.28mm. Although natural disturbances are important in mediating elevation gain in some situations, constant allochthonous sediment deposition probably matters most on these Pacific high islands, and is especially helpful in certain hydrogeomorphic zones. Fringe mangrove forests are most susceptible to sea-level rise, such that protection of these outer zones from anthropogenic disturbances (for example, harvesting) may slow the rate at which these zones convert to open water.

Levels of crop residue removal must be determined to prevent degradation of soil physical and chemical properties resulting from soil organic carbon (SOC) loss. Carbon inputs from crop residues and an estimate of inputs from roots and rhizodeposition (C sub(return)) were calculated and compared with changes in SOC after seven cropping seasons at Akron, CO. Tillage treatments included a chisel plow (CP) and a no-till (NT) treatment. A crop rotation alternating grasses and broadleaf crops was compared with continuous corn (Zea mays L.). Irrigation treatments included water application to meet evapotranspiration demand or application only during the reproductive stage of each crop. Total C sub(return) varied from 25 Mg ha super(-1) for the delayed irrigation, crop rotation plots to 63 Mg ha super(-1) for the fully irrigated, continuous corn plots. The change in SOC in the surface 30 cm of soil varied from -0.8 Mg SOC ha super(-1) for the rotation plots to a gain of 2.8 Mg ha super(-1) for the continuous corn plots after 7 yr. Correlating crop residue input with change in SOC showed that about 4.6 Mg ha super(-1) yr super(-1) C sub(return) is needed to maintain SOC levels for NT cropping systems and an average of 7.4 Mg ha super(-1) yr super(-1) C sub(return) is needed to maintain SOC levels under chisel tillage. Continuous corn was the only system that consistently provided sufficient crop residue to maintain SOC levels. Residue removal for off-farm use should consider only amounts that can be harvested without decreasing SOC levels.

The objective of this research was to evaluate the interactive effect of soil type, irrigation, and meteorological conditions on the water use and lint yield of cotton grown in four U.S. Great Plains soils. Cotton was grown in 2005 through 2007 in 48 weighing lysimeters which contained clay loam, silt loam, sandy loam, or fine sand at Bushland, TX, with irrigation beginning after emergence. The seasonal heat units (HU) from planting to harvest were 1010C in 2005, 1075C in 2006, and 985C in 2007. From seedling to beginning boll development, reference evapotranspiration averaged 7.6 mm in 2005, 8.5 mm in 2006, and 6.7 mm in 2007. Lint yield was significantly related to open boll number at harvest in all soils and years. Averaged cotton lint yields for the 2005 and 2007 full and deficit irrigation treatments were significantly larger in the fine sand (160 g m super(-2)) than in the other soils (126 g m super(-2)). In 2006, cotton lint yield in the fine sand was significantly smaller (101 g m super(-2)) than the average of the other soils (147 g m super(-2)). Cotton lint yield increased in the silt loam soil and decreased in the fine sand as seasonal HU increased.

We evaluated the effect of long-term application of poultry litter and inorganic N fertilizer on crop N uptake, soil N fractions, and N losses in conservation and conventional tillage with or without cover crop at the 0- to 20-cm depth in a Decatur silt loam (clayey, kaolinitic, thermic, Typic Paleudults) in northern Alabama. Treatments were incomplete factorial combinations of three tillage practices [no-till (NT), mulch till (MT), and conventional till (CT)], two cropping systems [cotton (Gossypium hirsutum L.)-cotton-corn (Zea mays L.) and rye (Secale cereale L.)/cotton- rye/cotton-corn], and two N fertilization sources and rates (0 and 100 kg N ha super(-1) from NH sub(4)NO sub(3) and 100 and 200 kg N ha super(-1) from poultry litter). Nitrogen fractions were soil total N (STN), particulate organic N (PON), microbial biomass N (MBN), potential N mineralization (PNM), NH sub(4)- N, and NO sub(3)-N. Crop N uptake varied among treatments and years and total uptake from 1997 to 2005 was greater in rye/cotton-rye/cotton-corn than in cotton-cotton-corn and greater with NH sub(4)NO sub(3) than with poultry litter at 100 kg N ha super(-1). After 10 yr, STN and PON contents at 0 to 20 cm were greater in NT with poultry litter than in other treatments, except in CT with poultry litter, resulting in N storage at 38 kg N ha super(-1) yr super(-1) with poultry litter compared with loss at 4 kg N ha super(-1) yr super(-1) with NH sub(4)NO sub(3). The MBN, PNM, and NO sub(3)-N contents were greater with poultry litter than with NH sub(4)NO sub(3), regardless of tillage. Calculation of estimated N balance showed that poultry litter conserved N at 191 to 556 kg N ha super(-1) compared with -75 to 201 kg N ha super(-1) with NH sub(4)NO sub(3). Poultry litter application can increase soil N storage and mineralization and reduce the potential for N loss compared with inorganic N fertilization, thereby reducing the need for N fertilization and environmental N contamination.

The annual change in forest DWM C stocks and other attributes (e.g., size and decay class changes) was assessed using a forest inventory in the north central United States to provide an empirical assessment of strategic-scale DWM C flux. Using DWM inventory data from the USDA Forest Service's Forest Inventory and Analysis program, DWM C stocks were found to be relatively static across the study region with an annual flux rate not statistically different from zero. Mean C flux rates across the study area were [[PQ_REPLACE:[math]]]-0.25, [[PQ_REPLACE:[math]]]-0.12, [[PQ_REPLACE:[math]]]-0.01, and [[PQ_REPLACE:[math]]]-0.04 (Mg/ha/yr) for standing live trees, standing dead trees, coarse woody debris, and fine woody debris, respectively. Flux rates varied in their both magnitude and status (emission/sequestration) by forest types, latitude, and DWM component size. Given the complex dynamics of DWM C flux, early implementation of inventory remeasurement, and relatively low sample size, numerous future research directions are suggested.

The idea of this approach of biosorbent fabrication is to promote the native zeolite adsorption performance and thus to prepare more efficient amphoteric tailored product for specific environmental uses. Flexible component i.e. alginate biopolymer with a rigid component (pulverized) zeolite were crosslinked using Fe(III) and Ca(II) chlorides,. The extent of adsorption was found to be a function of contact time, adsorbate concentration and adsorbent dose. The equilibrium adsorption data for above pollutants were fitted to Freundlich and Langmuir isotherms, respectively. Moessbauer spectroscopy was used for the ferric and ferrous iron ratio detection in the zeolite polletized with biopolymeric alginate samples and Scanning Electron Microscopy with Atomic Force Microscopy helped to visualize their surface texture and morphology.

An increase in emerging non-indigenous bacterial diseases poses a real threat to US agriculture. The United States has 100,000 miles of shoreline and 6,000 miles of border, making possible easy introduction of crop pests and diseases. Most threatening to crops are the cross-domain enteric bacteria. In contrast to animals, crops have hundreds of major diseases and development of molecular-based detection protocols for each pathogen is impossible with current technology. Rathayibacter toxicus, a neurotoxin-produdng bacterium transmitted by a seed gall nematode, is an example of a high-risk Select Agent. The bacterium infects seeds of grasses without showing any symptoms, often resulting in the death of grazing cattle. A prerequisite for the control of any disease is sensitive detection and proper identification of the causal organism. Detecting bacteria in samples of plants showing symptoms is relatively simple, whereas detection in asymptomatic tissues is difficult due to the extremely low numbers of the target pathogen present. Rapid serological assays work well with symptomatic tissues but not from asymptomatic tissue when bacteria levels are below sensitivity limits. Classical agar-plating assays are 1,000 fold more sensitive then serology or PCR. However, agar plating assays take from 3 to 5 days and require pathogenicity tests to confirm the identity. PCR-based assays allow for rapid, accurate identification but are insensitive due to use of 1 kL sample in comparison to 100 kL used for agar plating. To overcome this disadvantage, an enrichment technique termed BIO-PCR can be used in combination with agar plating for detection with asymptomatic tissues. The key to developing a successful BIO-PCR protocol s to determine the time required for development of pin point-size colonies to appear. For most plant pathogens 15 to 24 hours is sufficient time, whereas for the cross-domain bacteria only 1 to 2 hours is needed. For greater sensitivity, BIO-PCR can be combined with 96-well microliter plates with membranes to detect a single viable cell per 10 mL of an aqueous sample.

A cocktail of 8 serotypes of Salmonella spp. was inoculated into ground beef supplemented with sodium lactate (NaL) (1.5% and 3%) and-or oregano oil (0.5% and 1%) to obtain approximately 8 log CFU-g. The ground beef samples (3 g) were vacuum-packed and heated at 60, 65, or 71 C in a circulating water bath for selected times to inactivate approximately 5 to 6 log CFU-g of the pathogen, and then stored at 15 C for 15 and 30 d. Results show that especially at the lower cooking temperatures, addition of oregano oil increased the inactivation rate of Salmonella spp., whereas addition of NaL alone exhibited a protective effect against lethality and decreased the rate. Addition of combinations of oregano oil and NaL overcame this protective effect. During subsequent posttreatment storage for 15 d, Salmonella populations in the controls and in samples containing 0.5% oregano (60 and 65 C) or 1% oregano oil (60 C) increased to 4.5 to 6 log CFU-g. The values for all other samples were at or near undetectable levels. Results from the 30-d storage study were similar. These findings indicate that lactate and oregano oil may be used to render Salmonella spp. more susceptible to the lethal effect of heat and to inhibit growth of Salmonella spp. that survive heat treatments.

Strip till treatments were compared to conventional grower tillage practices in fifty-six 15-x 25-m (48-x 80-ft) side-by-side plots. Both treatments were flat planted with no ridges or beds. All strip tillage and fertilization was done in the fall after removal of a malt barley crop. Conventional tillage was done in the fall at the Sidney site and in the spring at the Nesson site. Thirty-centimeter (12-in.) wide strips were tilled directly into the straw residues about 20 cm (8 in.) deep using straight and paired fluted coulters and a modified parabolic ripping shank followed by a crows-foot packer wheel. Toothed-wheel row cleaners were installed in front of the straight coulter to move loose residue to the side to avoid plugging. At the same time, dry fertilizer was shanked (banded) about 8 to 13 cm (3 to 5 in.) below the anticipated seed placement location. Sugarbeet were planted about 2.5 cm (1 in.) deep with 60-cm (24-in.) spacing between rows in the spring. Toothed-wheel row cleaners were also placed in front of each row on the planter to move any residue displaced by winter storms. Operation of the strip tillage machine required about 25 tractor horsepower per row, but substantial fuel savings were realized with this system by reducing the number of tractor equipment field passes by up to 75%. In 2004, 2006, 2007, and 2008 there were no significant differences in yields, or sugar production between the two tillage treatments; however, in 2005 the strip tilled plots produced about 17% greater yields (tonnage and gross sugar). This benefit in 2005 was primarily due to the standing straw stubble in the strip tilled plots that protected sugarbeet seedlings from blowing soil during a spring wind storm that severely damaged seedlings in the conventionally tilled plots where there was no surface crop residue. It was concluded that strip tillage must be considered as part of a larger cropping system that affects timing and equipment choices for planting, cultivation, spraying, and harvesting as well as tillage and other cultural practices. Based on these results, it is generally recommended that strip tillage should be performed in the fall on clay soils in eastern Montana where it has been shown to result in better seedbed conditions than spring strip tillage. Whereas lighter, sandy soils would probably produce equally well when strip tilled in the spring, which could then be combined with planting into a single pass tillage, fertilizing, and planting operation. Banding fertilizer is highly recommended under strip till to increase fertilizer use efficiencies and reduce input costs. RTK-GPS guided steering in combination with some type of mechanical steering assistance on the implements are also recommended for both strip tilling, planting, and cultivation (if needed).

Kernels were grouped into one of six symptom categories depending on the degree of visible discoloration and bright green-yellow fluorescence (BGYF) or bright orange fluorescence (BOF). Kernels visibly discolored (225% of their surface) and having BGYF contained over 57% of the aflatoxin. However, kernels approximately 50% discolored without BGYF contained over 35% of the aflatoxin. Over 33% of the fumonisin was found in kernels that were visibly discolored and had BOF. The remaining fumonisin was in asymptomatic kernels at low levels. Sorting tests for removing mycotoxin-contaminated kernels were performed using a dual wavelength high-speed commercial sorter. In one pass through the sorter, aflatoxin was reduced by an average of 46%, and fumonisin was reduced by 57% while removing 4% to 9% of the corn. Re-sorting accepted kernels a second time resulted in an 88% reduction in aflatoxin while removing approximately 13% of the com. Approximately half of the aflatoxin missed by the optical sorter was found in larger kernels showing BGYF but no other symptoms, with the remaining aflatoxin in smaller kernels where the germ was damaged by insect feeding.

P. Beauv.] represents an alternative to temperate grasses typically used in forage-livestock systems. Our objective was to compare the productivity, nutritive value, and persistence of diverse meadow fescue cultivars with that of tall fescue [Lolium arundinaceum (Schreb.) Darbysh.] and orchardgrass (Dactylis glomerata L.) when harvested by regimes representing lax and severe hay production and rotational grazing. 'Azov' (plant introduction strain cross), 'Bartura' (commercial cultivar), and 'Hidden Valley' (naturalized population) meadow fescue, 'Barolex' tall fescue, and 'Bronc' orchardgrass were harvested infrequently (40- to 65-d harvest interval) or frequently (when plants reached 25-cm sward height) to a 5- or 10-cm residual sward height (RSH) at two Wisconsin locations in 2 yr. Annual dry matter (DM) yield of all grasses was greater when harvested infrequently (7.46 Mg ha super(-1)) than frequently (5.92 Mg ha super(-1)), or at 5 cm (7.52 Mg ha super(-1)) than 10-cm RSH (5.88 Mg ha super(-1)). Tall fescue and orchardgrass annual yield was greater than that of all meadow fescues when harvested infrequently, but differences among grasses were relatively small when harvested frequently, particularly at 10-cm RSH. Neutral detergent fiber digestibility (NDFD) of meadow fescue was 30 to 80 g kg super(-1) neutral detergent fiber (NDF) greater than that of tall fescue or orchardgrass at every harvest in all environments. Meadow fescue cultivars were less persistent than tall fescue after 2 yr, but were usually equal to or more persistent than orchardgrass. Meadow fescue should be considered as a viable alternative to tall fescue and orchardgrass in temperate, managed intensive rotational grazing systems due to its comparable yield and superior digestibility.

Decisions to target escaped weeds, and justify the added expense, require knowledge of the biological significance of low weed population densities on the crop. The objectives were to (i) quantify giant ragweed (Ambrosia trifida L.) area of influence (AOI) on sweet corn, and (ii) investigate potential links among giant ragweed AOI and crop growth, development, and yield attributes. All measured crop attributes were influenced by giant ragweed AOI, including plant height near silk emergence (HT), thermal time to silk emergence, green ear mass (GMASS), husked ear mass (HMASS), filled ear length (LENGTH), ear width at midpoint (WIDTH), and kernel moisture (MOIST). Proportion of silked plants declined for sweet corn within 160 cm of giant ragweed, with less than one-half of the crop plants producing a marketable ear within 42 cm of giant ragweed. Weed interference harmed ear attributes most when crop development was delayed, as evidenced by path analysis of giant ragweed's direct and indirect associations with yield attributes. Even the lowest population density of giant ragweed can be costly, with yield loss estimates ranging from $0.86 to $8.75 per weed plant, depending on crop market type.

The objective of this study was to compare profitability of moldboard plow, chisel plow, and no-tillage with or without composted animal manure in a corn (Zea mays L.)-soybean [Glycine max (L.) Merr.]-wheat (Triticum aestivum L.)/clover (Trifolium spp.) rotation during three rotation cycles. Corn and soybean grain and seed yield exhibited a tillage x compost amendment interaction. Yield in moldboard and chisel plow with or without compost was similar, but yield in no-tillage with compost was 8 and 5% greater than without compost for corn and soybean. Wheat yielded 5% higher in moldboard and chisel plow than no-tillage and 4% higher in compost than no-compost amendment. Wheat returns were similar among tillage and 7% higher when compost was amended. Corn production with or without compost amendment had similar returns in moldboard plow. Corn in chisel plow with compost had 8% greater returns than the no-compost treatment. Corn in no-tillage with compost had 15% greater returns with compost amendment than without. Similar corn returns were generated for all tillage systems if compost was applied. Soybean production using no-tillage had 9% greater returns than without compost and greater returns than moldboard and chisel plow with or without compost. Summing returns across the three-crop rotation indicated cycling nutrients through compost application exhibits a functional synergy in no- tillage and chisel plow but not moldboard plow for these crops, which enhances their profitability.

It has been demonstrated that chemical extractability of Cd is persistently decreased in biosolids-amended soils. This study was conducted to determine if Cd phytoavailability in long-term biosolids-amended soils was also persistently decreased. Paired control and biosolids-amended soils were collected from three experimental sites where large cumulative rates of biosolids were applied about 20 yr ago. The pH of all soils [in 0.01 mol L super(-1) Ca(NO sub(3)) sub(2)] was adjusted to 6.5 c 0.2. Increasing rates of Cd- nitrate (from 0 to 10.0 mg Cd kg super(-1) soil) enriched in super(111)Cd stable isotope were added to all soils, and Romaine lettuce (Lactuca sativa L. var. longifolia Lam.) was grown in pots to bioassay phytoavailable Cd. After harvest, Cd concentrations in shoots and labile pool of Cd (Cd sub(L)) in soils were determined. The relationship between added salt-Cd and Cd concentrations in lettuce shoots was linear for all soils tested. Ratios of (shoot Cd):(soil Cd) slopes were highest in the control soils. Biosolids amendment decreased (shoot Cd):(soil Cd) slopes to varied extent depending on biosolids source, properties, and application rate. The decrease in slope in comparison to the control was an indication of the lower phytoavailability of Cd in biosolids- amended soils. A significant negative correlation existed between Cd uptake slopes and soil organic matter, free and amorphous Fe and Al oxides, Bray-P, and soil and plant Zn. Biosolids-Cd was highly labile (%L 80-95) except for Fulton County soil (%L = 61).

We determined surface residue cover from rye (Secale cereale L.) or oat (Avena sativa L.) cover crops after two strip tillage systems (narrow vs. wide) and planting operations with different row configurations (single vs. twin). We also compared plant populations, yields, and total sound mature kernels for three peanut cultivars ('ANorden', 'AP-3', and 'Georgia-02C') across each treatment combination. Seven site-years were examined across similar soil types in Alabama and northern Florida during the 2004 to 2006 growing seasons. The highest surface residue counts were for the narrow tillage system planted in single rows. Final plant stands were influenced by an interaction between cultivar and row configuration, with 'ANorden' planted in single rows below recommended rates. Peanut yields were affected by strip tillage system and row configuration, but differences among cultivars were also observed. Twin- row peanut yields were 5% greater than single-row peanut yields in the narrow strip tillage system but were similar across strip tillage systems. Cultivars 'AP-3' and 'Georgia-02C' yielded 20% higher than 'ANorden'. Total sound mature kernels were only affected by peanut cultivar, with the cultivar 'Georgia-02C' producing the highest-quality peanut, followed by 'ANorden' and 'AP-3'. These results indicate that growers interested in using twin rows for peanut production can also take advantage of a narrow strip tillage system that maximizes surface residue coverage and subsequent benefits.

We conducted a field experiment in the North Carolina Piedmont to compare the effects of three maize residue treatments (unchopped, chopped, and removed) on Fusarium head blight (FHB) in two winter wheat cultivars. While FHB levels were too low for meaningful comparisons, severe epidemics of barley/cereal yellow dwarf virus (YDV) did develop in 2 yr out of 3. In those 2 yr, YDV symptoms of discoloration and stunting were greater (P < 0.001), and yield was lower (P < 0.01), in plots with maize residue than in plots without maize residue. In the third year, when planting was late because of a severe fall drought, no YDV epidemic developed, and there were no differences in wheat yield due to maize residue treatment (P = 0.25). In the first 2 yr, leaf samples from all plots were assayed for viruses using a multiplexed reverse transcription polymerase chain reaction (RT-PCR) method. The most common YDV serotypes were MAV, PAV, and RPV, which were each detected in at least 46 and 74% of samples in the 2 yr, respectively. Our finding of greater YDV severity in association with surface residue is consistent with the reported aphid preference for high-intensity yellow colors, which we hypothesize attracted aphids preferentially to residue-covered plots in the fall. Our results support a recommendation of seed or seedling insecticide treatment when planting wheat into heavy unincorporated maize residue in the U.S. Piedmont.

The development of schemes to mitigate such degradation requires a characterization of the underlying transport processes. The objectives of this study were to develop annual and seasonal load-discharge relationships for suspended sediment (SS), total nitrogen (TN), and total phosphorus (TP) losses from a small mixed land use watershed and to use these relationships to explicate the annual and monthly patterns of losses of these species. Data from 1996 to 2004 were used to develop load-discharge relationships for SS, TN, and TP at the HP#6 watershed, a subwatershed of the Balhan reservoir watershed located in Bongdam-myun and Paltan-myun, Gyeonggi-do, Korea. Standard least squares curve fitting and S-estimation procedures were used to fit power functions to the data collected over this time period. The fitted load-discharge relationships are indicative of seasonal variations in SS and TN and of TP losses from HP#6. The exponents of the fitted power functions for TN and TP in the fall, for TP in summer season, and for SS in all seasons are >1, indicating that the concentrations of these species increase as flow rate increases. Most of the SS, TN, and TP transported in runoff left the watershed between April and September; thus, cost-efficient strategies can be established by focusing on this period. Further study of the seasonal variations is required for a better characterization of seasonal losses of SS, TN, and TP in runoff from the HP#6 watershed.

Accurate information on contaminant-pathways could provide a basis for mitigation through well-targeted approaches. This study determined dynamics of nitrate-N, total P, Escherichia coli, and sediment during a runoff event in Tipton Creek, Iowa. The watershed, under crop and livestock production, has extensive tile drainage discharging through an alluvial valley. A September 2006 storm yielded 5.9 mm of discharge during the ensuing 7 d, which was monitored at the outlet (19,850 ha), two tile-drainage outfalls (total 1856 ha), and a runoff flume (11 ha) within the sloped valley. Hydrograph separations indicated 13% of tile discharge was from surface intakes. Tile and outlet nitrate-N loads were similar, verifying subsurface tiles dominate nitrate delivery. On a unit-area basis, tile total P and E. coli loads, respectively, were about half and 30% of the outlet's; their rapid, synchronous timing showed surface intakes are an important pathway for both contaminants. Flume results indicated field runoff was a significant source of total P and E. coli loads, but not the dominant one. At the outlet, sediment, P, and E. coli were reasonably synchronous. Radionuclide activities of super(7)Be and super(210)Pb in suspended sediments showed sheet-and-rill erosion sourced only 22% of sediment contributions; therefore, channel sources dominated and were an important source of P and E. coli. The contaminants followed unique pathways, necessitating separate mitigation strategies. To comprehensively address water quality, erosion-control and nitrogen-management practices currently encouraged could be complemented by buffering surface intakes and stabilizing stream banks.

Furthermore, no long-term evaluation of net global warming potential (GWP) for grassland ecosystems in the northern Great Plains (NGP) has been reported. Given this need, we sought to determine net GWP for three grazing management systems located within the NGP. Grazing management systems included two native vegetation pastures [moderately grazed pasture (MGP), heavily grazed pasture (HGP)] and a heavily grazed crested wheatgrass [Agropyron desertorum (Fisch. ex. Link) Schult.] pasture (CWP) near Mandan, ND. Factors evaluated for their contribution to GWP included, 1) CO sub(2) emissions associated with N fertilizer production and application, 2) literature-derived estimates of CH sub(4) production for enteric fermentation, 3) change in soil organic carbon (SOC) over 44 yr using archived soil samples, and 4) soil-atmosphere CH sub(4) and N sub(2)O flux over three yr using static chamber methodology. Analysis of SOC indicated all pastures to be sinks for SOC, with sequestration rates ranging from 0.39 to 0.46 Mg C/ha/yr. All pastures were minor sinks for CH sub(4) (<2.0 kg CH sub(4)-C/ha/yr). Greater N inputs within CWP contributed to annual N2O emission nearly three-fold greater than HGP and MGP. Due to differences in stocking rate, CH sub(4) production from enteric fermentation was nearly three-fold less in MGP than CWP and HGP. When factors contributing to net GWP were summed, HGP and MGP were found to serve as net CO sub(2) sinks, while CWP was a net CO sub(2) source. Values for GWP and greenhouse gas intensity (GHGI), however, indicated net reductions in GHG emissions can be most effectively achieved through moderate stocking rates on native vegetation in the NGP.

Grassed waterways can control erosion while transmitting this runoff offsite, but are generally ineffective in removing dissolved agrochemicals. In this study, we routed runoff from one tilled (0.67 ha) and one no-till watershed (0.79 ha) planted to corn (Zea mays L.) into parallel, 30-m-long grassed waterways. Two 46-cm-diam. filter socks filled with composted bark and wood chips were placed 7.5 m apart in the upper half of one waterway and in the lower half of the other waterway to determine if they decreased concentrations of sediment and dissolved chemicals. Automated samplers were used to obtain samples above and below the treated segments of the waterways for two crop years. The filter socks had no significant effect (P < 0.05) on sediment concentrations for runoff from the no-till watershed, but contributed to an additional 49% reduction in average sediment concentration compared with unamended waterways used with the tilled watershed. The filter socks significantly increased the concentrations of Cl, NO sub(3)-N, PO sub(4)-P, SO sub(4), Ca, K, Na, and Mg in runoff from at least one watershed, probably due to soluble forms of these ions in the compost. The estimated additional amounts of these ions contributed by the socks each year ranged from 0.04 to 1.2 kg, thus were likely to be inconsequential. The filter socks contributed to a significant (P < 0.05) additional reduction in dissolved glyphosate [N-(phosphonomethyl)glycine] (5%) and alachlor [2-chloro-N-(2,6-diethylphenyl)-N-(methoxymethyl)acetamide] (18%) concentrations for the tilled watersheds, but this was insufficient to reduce alachlor concentrations to acceptable levels.

In this study, we amended poultry, dairy, and swine manures with two rare earth chlorides, lanthanum chloride (LaCl sub(3) super(.)7H sub(2)O) and ytterbium chloride (YbCl sub(3) super(.)6H sub(2)O), to evaluate their effects on P solubility in the manure following incubation in the laboratory as well as on the fate of P and rare earth elements (REEs) when manures were surface-applied to packed soil boxes and subjected to simulated rainfall. In terms of manure P solubility, La:water-extractable P (WEP) ratios close to 1:1 resulted in maximum WEP reduction of 95% in dairy manure and 98% in dry poultry litter. Results from the runoff study showed that REE applications to dry manures such as poultry litter were less effective in reducing dissolved reactive phosphorus (DRP) in runoff than in liquid manures and slurries, which was likely due to mixing limitations. The most effective reductions of DRP in runoff by REEs were observed in the alkaline pH soil, although reductions of DRP in runoff from the acidic soil were still >50%. Particulate REEs were strongly associated with particulate P in runoff, suggesting a potentially useful role in tracking the fate of P and other manure constituents from manure-amended soils. Finally, REEs that remained in soil following runoff had a tendency to precipitate WEP, especially in soils receiving manure amendments. The findings have valuable applications in water quality protection and the evaluation of P site assessment indices.

Populations throughout the Appalachian Ecoregion AN - 744682745; 12680626 AB - Over the last three decades the fungus Discula destructiva Redlin has severely impacted Cornus florida L. (flowering dogwood-hereafter 'dogwood') populations throughout its range. This study estimates historical and current dogwood populations (number of trees) across the Appalachian ecoregion. Objectives were to (1) quantify current dogwood populations in the Appalachian ecoregion, (2) quantify change over time in dogwood populations, and (3) identify trends in dogwood population shifts. Data from the USDA Forest Service Forest Inventory and Analysis (FIA) database were compiled from 41 FIA units in 13 states for county-level estimates of the total number of all live dogwood trees on timberland within the Appalachian ecoregion. Analysis of covariance, comparing historical and current county-level dogwood population estimates with average change in forest density as the covariate, was used to identify significant changes within FIA units. Losses ranging from 25 to 100 percent of the sample population ([[PQ_REPLACE:[math]]]P .05) were observed in 33 of the 41 (80 percent) sampled FIA units. These results indicate that an important component of the eastern deciduous forest has experienced serious losses throughout the Appalachians and support localized empirical results and landscape-scale anecdotal evidence.

Average fallow PSE for Great Plains wheat (Triticum aestivum L.)-fallow (W-F) production systems have ranged widely (10-53%). Study objectives were to compare PSE in conventionally tilled (CT) and no-till (NT) W-F systems over 10 seasons at Akron, CO, against published values and to identify meteorological conditions that may influence PSE. Soil water measurements were made four times during each fallow period, dividing the fallow season into three periods (first summer, fall-winter-spring, second summer). Precipitation was measured in the plot area and other meteorological conditions were measured at a nearby weather station. The 14-mo fallow PSE averaged 20% (range 8-34%) for CT and 35% (range 20-51%) for NT, much lower than previously reported for NT at Akron. During the second summer period, PSE was not different between the two systems. The largest PSE difference between the two systems was seen during the fall-winter-spring period (32 vs. 81%). Fallow soil water increased an average of 111 mm under CT and 188 mm under NT. The PSE during the three fallow periods was related to tillage, precipitation, air temperature, vapor pressure deficit, and wind speed, but sometimes counter-intuitively. A simple linear regression using inputs of tillage system, percentage of fallow precipitation events with amounts between 5 and 15 mm, and percentage of fallow precipitation events with amounts > 25 mm can be used to estimate PSE and fallow period water storage.

This study examined the yields and juice quality of four sugarcane cultivars (CP 88-1762, CP 89-2143, CP 89-2376, and CP 96-1252) maintained at constant water-table depths near 20 (20CWT) and 45 cm (45CWT) and with periodic summer flooding. Prescribed lysimeters were flooded for the first 7 d of five, five, and four 21-d cycles in 2005 (plant-cane crop), 2006 (first-ratoon crop), and 2007 (second-ratoon crop), respectively. These treatments generally remained flooded during the next 7 d while they received no irrigation or drainage, and were drained to 20 (20FWT) or 45 cm (45FWT) for the final 7 d of each cycle. Water treatment affected CRS only in the plant-cane crop, where 45CWT had lower CRS than 20CWT, 20FWT, and 45FWT. Yields of cane and sucrose of CP 89-2143 were least affected by water treatments. Reductions in cane and sucrose yields at a 20 compared with a 45 cm water-table depth were common for the other three cultivars, but yields under the 20CWT vs. 20FWT or 45CWT vs. 45FWT treatments were generally similar. These results suggest that sugarcane roots function well in flood for up to 14 d, but do not grow well into saturated soil. This provides new options for sustaining high yields of sugarcane exposed to shallow water tables and floods; verification of root responses could enhance strategies to sustain yields while reducing P discharge.

Wheat hardness was predicted accurately by both NIR systems and results were in close agreement with reference values. The accuracy of predicting moisture content by either system was similar with predicted values within 0.5% moisture content of the reference values. Waxy character was predicted by the laser system with less accuracy than the SKNIR system, but tsetse fly pup %e sex was predicted with similar accuracies for both systems. Prediction equations derived from the laser spectra shew that wavelengths influencing classification models generally agree with published literature. Thus, this research shows that a NIR laser array system can be used to predict some grain and insect traits with accuracy similar to a commercial NIR system and some predictions may be improved if other wavelengths are used in the laser array system.

Data for this report were collected using a rapid appraisal approach. Specific, predetermined information on each nursery including its management and community support were collected using a mixed team of researchers. Data were verified for consistency with other sources. The technical elements of nursery management (water supply, fencing, daily care, pest protection) are significant for positive outcomes of a nursery. However, the extent to which they work or the motivation behind them are heavily reliant on stakeholder support. Successful schools in the competition combined technical and stakeholder components.

To quantify site fidelity, the tendency to return to and reuse previously occupied habitats, multistrata models (with water bodies as the strata) and potential function analyses were used. The probability of returning to previously used water bodies during all activity periods was typically greater than 80% and always greater than the probability of moving to other water bodies. Site fidelity models (with lake-specific movement transitions) were favored over those models that held movement transitions equal between lakes. Potential function analyses demonstrated that frogs were most strongly attracted to their original capture lakes rather than moving to the nearest available breeding or overwintering lake. Under current disturbances in high-elevation Sierra Nevada lakes (exotic trout, climate change), site fidelity is problematic because frogs return to lakes subject to drying or those with fish rather than dispersing to other lakes. Future recovery of declining species will need to focus efforts towards restoring habitats when animals maintain strong site fidelity even when their habitats deteriorate.Original Abstract: De 1997 a 2006, des modeles de marquage-recapture nous ont servi a estimer la fidelite au site de 1 250 grenouilles a pattes jaunes de la Sierra Nevada (Rana sierrae) dans le parc national de King's Canyon, Californie, E.-U., durant leur trois principales periodes d'activite, soit l'hivernage, la reproduction et l'alimentation. Afin de quantifier la fidelite au site, c'est-a-dire la tendance a retourner dans des habitats utilises anterieurement et a les exploiter de nouveau, nous utilisons des modeles a strates multiples (les plans d'eau representant les strates) et des analyses fonctionnelles potentielles. La probabilite de retourner dans un plan d'eau deja utilise est, dans l'ensemble des periodes d'activite, generalement de plus de 80 % et toujours plus elevee que la probabilite de se deplacer vers un autre plan d'eau. Nous preferons les modeles de fidelite au site avec des transitions de deplacement specifiques a chaque lac aux modeles qui presupposent que les transitions de deplacement sont egales pour tous les lacs. Les analyses fonctionnelles potentielles montrent que les grenouilles sont beaucoup plus fortement attirees vers le lac de leur premiere capture que portees a se deplacer vers le lac le plus proche de reproduction ou d'hivernage. Dans les conditions actuelles de perturbations dans les lacs de haute altitude de la Sierra Nevada (truites exotiques, changement climatique), la fidelite au site pose des problemes parce que les grenouilles peuvent retourner a des lacs sujets a la dessiccation ou des lacs contenant des poissons, plutot que se disperser vers d'autres lacs. La recuperation future des especes en declin devra concentrer ses efforts sur la restauration des habitats lorsque les animaux conservent une forte fidelite au site meme quand leurs habitats se deteriorent.

AN - 733607056; 19783700 AB - Various alkaloids found in endophyte-infected tall fescue have been shown to elicit different effects in the grazing animal. As part of an ongoing characterization of vascular response generated by different alkaloids, the objective of this study was to examine the vasoconstrictive potentials of ergonovine (a simple lysergic acid derivative) and alpha-ergocryptine, ergocristine, and ergocornine (all ergopeptine alkaloids) using bovine lateral saphenous veins (cranial branch) biopsied from fescue-naïve cattle. Segments (2 to 3 cm) of vein were surgically biopsied from healthy crossbred yearling cattle (n = 18; 274 +/- 8 kg of BW). Veins were trimmed of excess fat and connective tissue, sliced into 2 to 3 mm sections, and suspended in a myograph chamber containing 5 mL of oxygenated Krebs-Henseleit buffer (95% O(2)/5% CO(2); pH = 7.4; 37 degrees C). Tissue was allowed to equilibrate at 1 g of tension for 90 min before initiation of treatment additions. Increasing doses of each alkaloid (1 x 10(-10) to 1 x 10(-4) M) were administered every 15 min after buffer replacement. Data were normalized as a percentage of contractile response induced by a reference dose of norepinephrine (1 x 10(-4) M). Exposure of vein segments to increasing concentrations of ergocryptine, ergocristine, and ergonovine did not result in a contractile response until 1 x 10(-7) M, and ergocornine was even less potent (P < 0.05). Ergonovine had a greater maximal contractile intensity than ergocristine and ergocryptine (P < 0.05), with the 1 x 10(-4) M responses of ergonovine, ergocristine, ergocryptine, and ergocornine reaching maximums of 68.5 +/- 4.1, 45.5 +/- 4.5, 42.9 +/- 4.1%, and 57.2 +/- 9.9% of the norepinephrine maximum, respectively. The contractile response to increasing concentrations of ergonovine vs. ergocryptine, ergocristine, and ergocornine were opposite from previous evaluations of ergoline (e.g., lysergic acid) and ergopeptine (e.g., ergovaline) alkaloids using this bioassay, where the ergopeptine generated the greater contractile intensity. These data indicate that ergopeptines structurally different only at a single position of the peptide moiety do not exhibit differing contractile responses when considering contractile intensity. This difference may alter the potency when considering ergocornine was less potent than ergocryptine or ergocristine. These alkaloids may need to be considered when evaluating causative agents vasoconstriction associated with tall fescue-induced toxicosis.

Programme impact on food consumption from own production, land use, livestock ownership, and agricultural spending are evaluated using first difference and weighted estimators, in which weights are constructed from propensity scores. The programme is found to increase the value and variety of food consumed from own production and to increase land use, livestock ownership and crop spending. Impact estimates are found to differ across land use categories and PROCAMPO participation. Results support the hypothesis that transfers influence agricultural production and impacts are greater for households invested in agriculture. Reprinted by permission of Frank Cass & Co. Ltd.

In Delta Junction, Alaska plant communities in CRP fields are transitioning from grasslands to shrub dominated plant communities, which are resulting in compliance problems with program regulations that state ''fields must be maintained in a condition that permits easy conversion to cropland''. To determine plant succession and how previous land management and soils might influence the transition, we measured plant populations in 20 CRP fields throughout Delta Junction using modified-Whittaker plots. These data were combined with data on current management practices, previous farming history, soils, soil properties, diversity indices, and time since land was cleared and analyzed with nonmetric multidimensional scaling ordination to determine factors that influence plant succession. Time in the CRP was the only factor consistently influencing plant succession. As time in the CRP increased, the planted introduced grasses brome grass (Bromus inermis) and red fescue (Festuca rubra) and the native pteridophyte (Equisetum arvense) decreased, whereas a native grass (Calamigrostis canadensis), five native forb, two native shrub, and three native tree species increased. Plant diversity increased at a rate of more than 2 species per 1000m(2) per year. Regression analyses of plant species and plant groups using time in the CRP as the dependent variable resulted in the identification of outlier CRP fields with significantly more or less than expected covers of vegetation. All fields with these outliers had reasonable explanations for the differences in cover that were unrelated to the overall rate of plant succession. Current management practices will result in incompliant fields and different management practices that result in woody vegetation control is key to maintaining CRP fields in compliance.

We test the hypothesis that the distribution and success of Tamarix result from human modification of river-flow regimes. We conducted a natural experiment in eight ecoregions in arid and semiarid portions of the western United States, measuring Tamarix and native Populus recruitment and abundance at 64 sites along 13 perennial rivers spanning a range of altered flow regimes. We quantified biologically relevant attributes of flow alteration as an integrated measure (the index of flow modification, IFM), which was then used to explain between-site variation in abundance and recruitment of native and nonnative riparian plant species. We found the likelihood of successful recruitment of Tamarix to be highest along unregulated river reaches and to remain high across a gradient of regulated flows. Recruitment probability for Populus, in contrast, was highest under free-flowing conditions and declined abruptly under even slight flow modification (IFM > 0.1). Adult Tamarix was most abundant at intermediate levels of IFM. Populus abundance declined sharply with modest flow regulation (IFM > 0.2) and was not present at the most flow-regulated sites. Dominance of Tamarix was highest along rivers with the most altered flow regimes. At the 16 least regulated sites, Tamarix and Populus were equally abundant. Given observed patterns of Tamarix recruitment and abundance, we infer that Tamarix would likely have naturalized, spread, and established widely in riparian Communities in the absence of dam construction, diversions, and flow regulation in western North America. However, Tamarix dominance over native species would likely be less extensive in the absence of human alteration of river-flow regimes. Restoration that combines active mechanical removal of established stands of Tamarix with a program of flow releases conducive to native species establishment and persistence is hypothesized to facilitate the codominance of Populus in reaches where it has become rare. Our findings have implications for planning flow-related stream restoration, for developing realistic expectations for yield on investment in prescribed flow releases, and for planning flow-related interventions that might be possible if control and management of invasive plant species along rivers is a goal.

The effects of different WFS-containing amendments on turfgrass growth and nutrient content were tested by planting perennial ryegrass (Lolium perenne L.) and tall fescue (Schedonorus phoenix (Scop.) Holub) in different blends containing WFS. Blends of WFS were created with compost or acid-washed sand (AWS) at varying percent by volume with WFS or by amendment with gypsum (9.6 g gypsum kg super(-1) WFS). Measurements of soil strength, shoot and root dry weight, plant surface coverage, and micronutrients (Al, Fe, Mn, Cu, Zn, B, Na) and macronutrients (N, P, K, S, Ca, Mg) were performed for each blend and compared with pure WFS and with a commercial potting media control. Results showed that strength was not a factor for any of the parameters studied, but the K/Na base saturation ratio of WFS:compost mixes was highly correlated with total shoot dry weight for perennial ryegrass (r = 0.995) and tall fescue (r = 0.94). This was further substantiated because total shoot dry weight was also correlated with shoot K/Na concentration of perennial ryegrass (r = 0.99) and tall fescue (r = 0.95). A compost blend containing 40% WFS was determined to be the optimal amendment for the reuse of WFS because it incorporated the greatest possible amount of WFS without major reduction in turfgrass growth.

Manure spill clean- up consists of containing, removing, and land applying the contaminated water column, while P-enriched fluvial sediments remain in place. Therefore, the objectives of this study were to (i) understand how P partitions between the water column and fluvial sediments during a manure spill, and (ii) evaluate the efficacy of current manure spill clean-up methods to remediate manure contaminated sediments. Manure spill simulations were conducted using fluvarium techniques and sediments collected from three drainage areas of two drainage ditches. Sediments with the greatest clay content (33%) resulted in a significantly greater P buffering capacity (10.3 L kg super(-1)) and removed P from the water column at the greatest rate during the manure spill simulation relative to sediments with < 6% clay. Phosphorus uptake length for all sediments ranged from 574 to 815 m and the adsorption flux ranged from 8.9 to 16.7 mg m super(-2) h super(-1). After simulating the current manure spill remediation methods, P desorbed to the water from all sediments exceeded the Environmental Protection Agency total P criteria (0.076 mg L super(-1)) for the region by at least 67%. Furthermore, results from this study suggest that the current manure spill remediation method needs refining to mitigate P from the total fluvial system water column and sediment following a spill.

Our objective was to quantify seed production on nonflowering orchardgrass clones selected in cold-winter climates, but grown for seed in mild-winter climates. We evaluated 98 orchardgrass clones for seed production traits at four locations. Most plants (692%) flowered at the three northern locations, but only 38% flowered at Parlier, which may have a winter insufficiently cold for adequate floral induction and vernalization. Mean panicle number was lowest (11%) for plants selected at the location with the warmest winter conditions, and highest (37%) for plants selected at the location with the coldest winter conditions. These results confirm our expectations that the most desirable plants (nonflowering under cold winters and normal flowering under mild winters) should arise from selection under more severe winters. Selection for nonflowering under mild winter conditions simply leads to nonflowering plants under all conditions. These results demonstrate that individual orchardgrass genotypes are capable of dual phenotypic expression, flowering in mild-winter climates or expressing the nonflowering trait in cold-winter climates and that the expression of this trait depends on both the selection and evaluation location.

The MBFs are composed of inorganic N and P in compounds that are relatively loosely bound (MBF8) to more tightly bound (MBF9) mixtures using combinations of starch, cellulose, lignin, Al sub(2)(SO sub(4)) sub(3)18H sub(2)O, and/or Fe sub(2)(SO sub(4)) sub(3)3H sub(2)O to create a matrix that slowly releases the nutrients. One day after the first dairy manure application, E. coli numbers were greater in leachate from control columns than in leachate from columns receiving MBFs. After three dairy manure applications, E. coli and Enterococcus spp. numbers in leachates were not consistently different between controls and columns receiving MBFs. When MBF8 was applied to the soil, the total amount of DRP, TP, NH sub(4), and NO sub(3) in leachate was lower than in the control columns. Bermudagrass receiving MBFs had greater shoot, root, and total biomass than grass growing in the control columns. Grass shoot, root, and total biomass did not differ among columns receiving MBFs. Nitrogen and phosphorus bound to the Al sub(2)(SO sub(4)) sub(3)18H sub(2)O or Fe sub(2)(SO sub(4)) sub(3)3H sub(2)O-lignin- cellulose matrix become gradually available to plants over the growing season. The MBF8 and MBF9 formulations do not depend on organic or inorganic coatings to reduce N and P leaching and have the potential with further testing and development to provide an effective method to reduce N and P leaching from soils treated with animal waste.

A method is described here for estimating the magnitude of flux underestimation arising from chamber deployment. The technique is based on previously established gas transport theory and has been simplified to facilitate application while preserving the fundamental physical relationships. The method avoids the use of nonlinear regression but requires knowledge of soil properties including texture, bulk density, water content, temperature, and pH. Two options are presented: a numerical technique which is easily adapted to spreadsheet application, and a graphical method requiring minimal calculation. In both cases, the magnitude of theoretical flux underestimation (TFU) is determined, taking into account effects of chamber geometry and deployment time, the flux-calculation scheme, and properties of the soil and gas under consideration. Application to actual data and recent studies confirmed that TFU can vary widely within and across sites. The analysis also revealed a highly linear correlation between soil water content and TFU, suggesting that previously observed relationships between water content and trace gas flux may in part reflect artifacts of chamber methodology. The method described here provides a practical means of improving the absolute accuracy of flux estimates and normalizing data obtained using different chamber designs in different soils.

In the case of Salmonella, pigs can become colonized with the organism during transport and lairage from contaminated trailers and holding pens, resulting in increased pathogen shedding just prior to processing. Increased shedding, in turn, amplifies the likelihood of carcass contamination by magnifying the amount of bacteria that enters the processing facility. We conducted a series of experiments to test whether phage therapy could limit Salmonella infections at this crucial period. In a preliminary experiment done with small pigs (3 to 4 weeks old; 30 to 40 lb), administration of an anti-Salmonella phage cocktail at the time of inoculation with Salmonella enterica serovar Typhimurium reduced Salmonella colonization by 99.0 to 99.9% (2- to 3-log reduction) in the tonsils, ileum, and cecum. To test the efficacy of phage therapy in a production-like setting, we inoculated four market-weight pigs (in three replicates) with Salmonella enterica serovar Typhimurium and allowed the challenged pigs to contaminate a holding pen for 48 h. Sixteen naive pigs were randomly split into two groups which received either the anti-Salmonella phage cocktail or a mock treatment. Both groups of pigs were comingled with the challenged pigs in the contaminated pen. Treatment with the anti-Salmonella phage cocktail significantly reduced cecal Salmonella concentrations (95%; P < 0.05) while also reducing (numerically) ileal Salmonella concentrations (90%; P = 0.06). Additional in vitro studies showed that the phage cocktail was also lytic against several non-Typhimurium serovars.

Here, we describe the development of a genetic linkage map of Brachypodium. The genetic linkage map was developed with an F sub(2) population from a cross between the diploid Brachypodium lines Bd3-1 and Bd21. The map was populated with polymorphic simple sequence repeat (SSR) markers from Brachypodium expressed sequence tag (EST) and bacterial artificial chromosome (BAC) end sequences and conserved orthologous sequence (COS) markers from other grass species. The map is 1386 cM in length and consists of 139 marker loci distributed across 20 linkage groups. Five of the linkage groups exceed 100 cM in length, with the largest being 231 cM long. Assessment of colinearity between the Brachypodium linkage map and the rice genome sequence revealed significant regions of macrosynteny between the two genomes, as well as rearrangements similar to those reported in other grass comparative structural genomics studies. The Brachypodium genetic linkage map described here will serve as a new tool to pursue a range of molecular genetic analyses and other applications in this new model plant system.Original Abstract: Le Brachypodium distachyon (Brachypodium) a ete adopte comme espece modele chez les graminees.

This study evaluated gamagrass (Tripsacum dactyloides L.), topdressed with either 56 (LO) or 168 (HI) kg N ha super(-1), direct baled after mowing in the afternoon (PM/LO and PM/HI) or morning (AM/LO and AM/HI), wrapped with plastic film, and conserved as baleage. The four baleage treatments were evaluated by steers for dry matter intake (DMI), digestibility, and N retention. Neither harvest time nor N rate altered DMI (mean = 1.87 kg 100 super(-1) kg body weight). Digestion was similar between PM and AM baleage but greater (P = 0.05) for HI vs. LO N rate (536 vs. 506 g kg super(-1)) as was cellulose digestion (P = 0.02; 656 vs. 617 g kg super(-1)). The digestion of crude protein was greater (P = 0.01) in the AM vs. PM baleage (519 vs. 443 g kg super(-1)) and greater (P = 0.02) in HI vs. LO N rate (520 vs. 441 g kg super(-1)). Fermentations differed (P < 0.01) between PM and AM baleage, as pH averaged 5.4 and 4.5, respectively. Greatest (P < 0.01) amounts of alcohols and least fatty acids occurred in PM baleage and N rate reduced (P < 0.01) alcohols but increased fatty acids. Total nonstructural carbohydrates (TNC) prebaling was 120 g kg super(-1) in the PM and 97 g kg super(-1) in the AM, but baleage averaged <38 g kg super(-1) and explains the lack of steer response to the PM harvest. Gamagrass preserved well as baleage and was readily consumed, but the TNC fraction was not preserved.

The trap catches prey by very rapid closure, within a fraction of a second of the trigger hairs being touched twice. Generation of action potentials plays an important role in closure. Because electrical signals are involved in reduction of the photosynthetic rate in different plant species, we hypothesized that trap closure and subsequent movement of prey in the trap will result in transient downregulation of photosynthesis, thus representing the energetic costs of carnivory associated with an active trapping mechanism, which has not been previously described.Methods Traps were enclosed in a gas exchange cuvette and the trigger hairs irritated with thin wire, thus simulating insect capture and retention. Respiration rate was measured in darkness (R sub(D)). In the light, net photosynthetic rate (A sub(N)), stomatal conductance (g sub(s)) and intercellular CO sub(2) concentration (c sub(i)) were measured, combined with chlorophyll fluorescence imaging. Responses were monitored in the lamina and trap separately.Key Results Irritation of trigger hairs resulted in decreased A sub(N) and increased R sub(D), not only immediately after trap closure but also during the subsequent period when prey retention was simulated in the closed trap. Stomatal conductance remained stable, indicating no stomatal limitation of A sub(N), so c sub(i) increased. At the same time, the effective quantum yield of photosystem II ( sub(PSII)) decreased transiently. The response was confined mainly to the digestive zone of the trap and was not observed in the lamina. Stopping mechanical irritation resulted in recovery of A sub(N), R sub(D) and sub(PSII).Conclusions We put forward the first experimental evidence for energetic demands and carbon costs during insect trapping and retention in carnivorous plants, providing a new insight into the cost/benefit model of carnivory.

Leaf Stomata Harboring Cryptosporidium parvum Oocysts: a Potential Threat to Food Safety , AN - 21303788; 11915314 AB - Cryptosporidium parvum is a cosmopolitan microscopic protozoan parasite that causes severe diarrheal disease (cryptosporidiosis) in mammals, including humans and livestock. There is growing evidence of Cryptosporidium persistence in fresh produce that may result in food-borne infection, including sporadic cases as well as outbreaks. However, drinking and recreational waters are still considered the major sources of Cryptosporidium infection in humans, which has resulted in prioritization of studies of parasite etiology in aquatic environments, while the mechanisms of transmission and parasite persistence on edible plants remain poorly understood. Using laser scanning confocal microscopy together with fluorescein-labeled monoclonal antibodies, C. parvum oocysts were found to strongly adhere to spinach plants after contact with contaminated water, to infiltrate through the stomatal openings in spinach leaves, and to persist at the mesophyll level. These findings and the fact that this pathogenic parasite resists washing and disinfection raise concerns regarding food safety.

This 2-yr field study investigated soil P solubility and runoff P losses from two agricultural soils in the Mid- Atlantic region after land application of biosolids derived from different waste water treatment processes and poultry litter. Phosphorus speciation in the biosolids and poultry litter differed due to treatment processes and significantly altered soil P solubility and dissolved reactive P (DRP) and bioavailable P (FeO-P) concentrations in surface runoff. Runoff total P (TP) concentrations were closely related to sediment transport. Initial runoff DRP and FeO-P concentrations varied among the different biosolids and poultry litter applied. Over time, as sediment transport declined and DRP concentrations became an increasingly important component of runoff FeO-P and TP, total runoff P was more strongly influenced by the type of biosolids applied. Throughout the study, application of lime-stabilized biosolids and poultry litter increased concentrations of soil-soluble P, readily desorbable P, and soil P saturation, resulting in increased DRP and FeO-P concentrations in runoff. Land application of biosolids generated from waste water treatment processes that used amendments to reduce P solubility (e.g., FeCl sub(3)) did not increase soil P saturation and reduced the potential for DRP and FeO-P transport in surface runoff. These results illustrate the importance of waste water treatment plant process and determination of specific P source coefficients to account for differential P availability among organic P sources.

To identify a biosynthetic gene for the culmorin pathway, an expressed-sequence-tag database was examined for terpene cyclase genes. A gene designated CLM1 was expressed under trichothecene-inducing conditions. Expression of CLM1 in yeast (Saccharomyces cerevisiae) resulted in the production of a sesquiterpene alcohol, longiborneol, which has the same ring structure as culmorin. Gene disruption and add-back experiments in F. graminearum showed that CLM1 was required for culmorin biosynthesis. CLM1 gene disruptants were able to convert exogenously added longiborneol to culmorin. Longiborneol accumulated transiently in culmorin-producing strains. The results indicate that CLM1 encodes a longiborneol synthase and is required for culmorin biosynthesis in F. graminearum.

For the former, 3-g portions of inoculated ground beef were packaged in bags that were completely immersed in a temperature-controlled circulating water bath held at 65 C (149 F), 70 C (158 F), 75(167 F), and 80 C (176 F) for a predetermined length of time. For the latter, formed ground beef patties (95-g each) were inoculated with spore stock A or B of the Sterne strain and then cooked on a commercial open-flame gas grill or on a commercial clamshell electric grill to achieve target internal temperatures of either 71.1 C (160 F), 82.2 C (180 F), or 93.3 C (200 F). Cooking ground beef patties on commercial grills, resulted in reductions of ca. 0.8 to 3.5 log sub(10) CFU/g for spore stocks A and B of B. anthracis Sterne after heating to 71.1 C (160 F), 82.2 C (180 F), or 93.3 C (200 F) on either the open-flame gas grill which required ca. 9.6 min to reach the target internal temperatures or on the clamshell electric grill which required ca. 4.0 min to reach the target internal temperatures. In comparison, our data using a water bath system and heating at 65 to 80 C predict nearly 4 log reductions in spore levels for short times, 61/4 min, depending possibly on the temperature. Thus, our data suggest that models based on heating ground beef in a water bath is not a good predictor of reductions of levels of spores of B. anthracis Sterne strain that would be obtained when cooking ground beef patties on commercial grills under conditions that may be typically used by consumers and/or retail establishments. Nevertheless, our data validated that cooking ground beef patties on a commercial grill at a temperature considered to be "well-done" and a temperature (71.1 C; 160 F) recommended by the USDA/FSIS, is effective at killing spores of B. anthracis Sterne. Industrial relevance - Heating ground beef in a water bath or cooking ground beef patties on commercial grills under conditions simulating those that are used by consumers and/or that occur in retail food service establishments is effective at killing spores of B. anthracis Sterne.

The attention is focused on the band structure fluctuation (BSF) at Fermi level, which is induced by electron-phonon coupling in superconductors, and which is absent in the non-superconducting analogues. The BSF in superconductors results in breakdown of the adiabatic BOA. At these circumstances, chemical potential is substantially reduced and system is stabilized (effect of nuclear dynamics) in the antiadiabatic state at broken symmetry with a gap(s) in one-particle spectrum. Distorted nuclear structure has fluxional character and geometric degeneracy of the antiadiabatic ground state enables formation of mobile bipolarons in real space. It has been shown that an effective attractive e-e interaction (Cooper-pair formation) is in fact correction to electron correlation energy at transition from adiabatic into antiadiabatic ground electronic state. In this respect, Cooper-pair formation is not the primary reason for transition into superconducting state, but it is a consequence of antiadiabatic state formation. It has been shown that thermodynamic properties of system in antiadiabatic state correspond to thermodynamics of superconducting state. Illustrative application of the theory for different types of superconductors is presented.

The cultures were tested singly and in different combinations in milk (0 or 2% fat content) during incubation at 40C for up to 10h. Cell-free milk samples taken every 60min were tested for bacteriocin activity against Listeria monocytogenes. Pediocin activity was not detectable when P. acidilactici was inoculated into milk as a monoculture. When P. acidilactici was grown in combination with the yogurt starter cultures S. thermophilus and Lb. delbrueckii ssp. bulgaricus, pediocin concentration reached 3,200-6,400unitsml super(-1) after 8h of incubation. The results showed that pediocin producing pediococci may be useful adjunct components in mixed cultures of S. thermophilus and Lb. delbrueckii ssp. bulgaricus to amplify the bioprotective properties of fermented dairy foods against Listeria contamination.

Riparian vegetation composition, structure and abundance are governed to a large degree by river flow regime and flow-mediated fluvial processes. Streamflow regime exerts selective pressures on riparian vegetation, resulting in adaptations (trait syndromes) to specific flow attributes. Widespread modification of flow regimes by humans has resulted in extensive alteration of riparian vegetation communities. Some of the negative effects of altered flow regimes on vegetation may be reversed by restoring components of the natural flow regime.2. Models have been developed that quantitatively relate components of the flow regime to attributes of riparian vegetation at the individual, population and community levels. Predictive models range from simple statistical relationships, to more complex stochastic matrix population models and dynamic simulation models. Of the dozens of predictive models reviewed here, most treat one or a few species, have many simplifying assumptions such as stable channel form, and do not specify the time-scale of response. In many cases, these models are very effective in developing alternative streamflow management plans for specific river reaches or segments but are not directly transferable to other rivers or other regions.3. A primary goal in riparian ecology is to develop general frameworks for prediction of vegetation response to changing environmental conditions. The development of riparian vegetation-flow response guilds offers a framework for transferring information from rivers where flow standards have been developed to maintain desirable vegetation attributes, to rivers with little or no existing information.4. We propose to organise riparian plants into non-phylogenetic groupings of species with shared traits that are related to components of hydrologic regime: life history, reproductive strategy, morphology, adaptations to fluvial disturbance and adaptations to water availability. Plants from any river or region may be grouped into these guilds and related to hydrologic attributes of a specific class of river using probabilistic response curves.5. Probabilistic models based on riparian response guilds enable prediction of the likelihood of change in each of the response guilds given projected changes in flow, and facilitate examination of trade-offs and risks associated with various flow management strategies. Riparian response guilds can be decomposed to the species level for individual projects or used to develop flow management guidelines for regional water management plans.

Our previous work has shown that peptones capable of supporting the growth of various microorganisms can be produced from inexpensive animal proteins, including meat and bone meal, feather meal, and blood meal, through alkaline or enzymatic hydrolysis. In this work, we explore how these experimental peptones compare to commercial peptones in terms of performance characteristics other than chemical make-up; these characteristics can impact fermentation operating cost. It is shown that experimental peptone powders produced through enzymatic hydrolysis are highly hygroscopic and that their physical form is not stable to humid storage conditions; those produced through alkaline hydrolysis and commercial peptones are less hygroscopic. When used in growth medium, all peptones contribute haze to the solution; experiments show that the source of haze is different when using enzyme- versus alkali-hydrolyzed peptones. Alkali-hydrolyzed peptones and all peptones made from blood meal are stronger promoters of media foaming than the commercial peptones; some enzyme-hydrolyzed peptones support very little foam formation and are superior to the commercial peptones in this sense. Alkali-hydrolyzed peptones are roughly equivalent to commercial peptones in the coloration they contribute to media, while enzyme-hydrolyzed peptones contribute intense coloration to media. No peptone caused a significant change in the viscosity of media. The experimental peptones studied here may be acceptable low-cost substitutes for commercial peptones, but none is equivalent to the commercial products in all respects.

Czerniak. and Sinapsis alba L.], and Camelina [Camelina sativa (L.) Crantz.] planting dates have to be adjusted to prevent crop failures. These crops can be used as biofuel feedstocks and some mustard varieties can be used as a soil biofumigant. Knowledge of germination temperature optima/range for brassicas is critical for inclusion of these crops into crop rotations. The B. napus varieties 'Clearwater' (UI-C-1), 'DKW 13-86' (Roundup ready), and 'Gem' (UI-G-1); the mustards 'Caliente 61', 'Florida Broadleaf', 'Idagold', 'Kodiak Brown', and 'Pacific Gold', and the Camelina line 'NEB C-1' were germinated in the dark in Petri-dishes at 4, 10, 16, 21, 27 or 32 degree C for up to 12 days. The shortest time to maximum germination (2 days) for all but 'Florida Broadleaf' and 'Kodiak Brown' occurred at 16 degree C. 'NEB C-1' had the greatest percent germination at all temperatures except 32 degree C where it was lower; 'DKW 13-86' decreased with increased temperature; 'Clearwater', 'Gem', 'Pacific Gold' and 'Kodiak Brown' had optimum germination between temperature extremes; 'Caliente 61' had the lowest maximum percent germination at 4 degree C; 'Florida Broadleaf' had increased germination with increased temperature, and germination of 'Idagold' was not affected by temperature. Variability in Brassica seed germination in response to temperature indicates that there may be the opportunity for flexibility in the planting dates over which these crops can be sown.

Vera et al., Soil water balance trial involving capacitance and neutron probe measurements'' [Agric. Water Manage. 96 (2009) 905-911] AN - 21107833; 11142585 AB - Vera et al. (2009) compared estimates of soil profile water content (mm) to a depth of 0.8 m made with the neutron moisture meter (NMM) and a multi-depth capacitance probe (MDCP), using measurements replicated in four drainage lysimeters (5 m x 5 m x 1.5-m deep). The NMM estimates of water content were reasonable and less than the saturated water content of the soil. The MDCP estimates were larger than the saturated water content value and therefore were physically unrealistic and erroneous. Clear effects of soil bulk electrical conductivity (BEC) on the MDCP estimates of soil water content were visible in the graphs published by Vera et al. (2009) but these effects and the physically unrealistic soil water content estimates were not acknowledged by those authors, who concluded that there were no important differences between the NMM and the MDCP. In the present manuscript, these errors are pointed out using physically based analysis and modeling of the effects of BEC on estimates of soil electrical permittivity and thus on estimates of water content by electromagnetic sensors operating in the same frequency range as the MDCP. The conclusions of Vera et al. (2009) are refuted using these analyses and by examining the relative statistical power of comparisons between lysimeter-derived changes in soil water storage (delta-S) and NMM-derived estimates of delta-S on the one hand, and between lysimeter-derived delta-S and MDCP-derived delta-S on the other hand. Since the standard deviations of NMM estimates of water content were much smaller than those of MDCP estimates of water content, the statistical power of the comparison between lysimeter-derived delta-S and NMM-derived delta-S is great, meaning that the lack of statistically significant difference between these estimates of delta-S leads to the conclusion that the NMM-derived delta-S values are the same as the lysimeter-derived values. That is, the NMM is a good tool for determining water contents and changes in profile water content over time, and thus is a good tool for soil water balance estimates of crop water use. The large standard deviations of MDCP estimates of water content lead to considerably less statistical power for the comparison of MDCP-derived delta-S and lysimeter-derived delta-S. Thus, the lack of a statistically significant difference in this case does not necessarily indicate that the MDCP is a good tool for determining delta-S.

One of the most valuable products from guayule is its hypoallergenic latex. However, little research has been done on the optimum harvest time for latex concentration and yield. The objective of this study was to determine the optimum harvest time during the growth cycle for latex content, plant biomass, and latex yield of guayule. Treatments consisted of three guayule lines (11591, AZ3, and G7-11TC) harvested every other month for 2 years. Plants were transplanted on 4 April 1995 at the University of Arizona Maricopa Agricultural Center, Maricopa, Arizona. Harvesting began in March 1998 and continued every other month through January 2000. Samples were analyzed for latex concentration and total biomass. Latex yields were calculated as the product of the latex concentration times the dry plant biomass. The experimental design was a randomized complete block with four replications. Results varied among lines and harvest dates. There appears to be enough differences among lines that planting lines selected for different optimum harvest dates would allow growers to spread the optimum harvest time throughout most of the year. This would also benefit processors by allowing them to reduce their production costs by spreading the harvest over several months instead of only a few months. More research must be done to determine whether specific environmental factors can be associated with the optimum harvest time and line specific harvesting guides such as growing degree days or other methods for determining optimum harvest date can be utilized in guayule.

Two soy proteins, a whey fraction, a porcine gelatin, and a meat & bone meal (MBM) extract were used in the flocculation test. It was found that MBM extract and porcine gelatin promoted clay flocculation, and flocculation was complete by 24 h with or without the addition of calcium chloride. The other tested proteins did not promote clay flocculation, but all of the proteins were found to be adsorbed to clay. The protein adsorptions were well described by the Langmuir model, and gelatin and MBM extract had higher maximum adsorption capacities than the other proteins. Zwitterionic buffer solutions at pH 5.5, 7.0, and 10.0 were tested in the flocculation experiments. Addition of the pH 5.5 buffer caused the two soy proteins to become clay flocculants and lowered the concentration of gelatin and MBM extract necessary to promote complete flocculation by 24 h. Calcium chloride was not required for flocculation. Under optimal testing conditions, the dried weight of gelatin or MBM extract was 2.6 and 17 times higher, respectively, than the weight of anionic PAM required for complete flocculation at 24 h.

In this study we report an acclimated lagoon nitrifying sludge that is capable of high rates of nitrification at temperatures from 5 (11.2 mg N/g MLVSS/h) to 20 (40.4 mg N/g MLVSS/h). The composition of the microbial community present in the nitrifying sludge was investigated by partial 16S rRNA gene sequencing. After DNA extraction and the creation of a plasmid library, 153 partial length 16S rRNA gene clones were sequenced and analyzed phylogenetically. Over 80% of these clones were affiliated with the Proteobacteria, and grouped with the b- (114 clones), g- (7 clones), and a-classes (2 clones). The remaining clones were affiliated with the Acidobacteria (1 clone), Actinobacteria (8 clones), Bacteroidetes (16 clones), and Verrucomicrobia (5 clones). The majority of the clones belonged to the genus Nitrosomonas, while other clones affiliated with microorganisms previously identified as having floc forming or psychrotolerance characteristics.

Crantz] oil by homogenous base-catalyzed transesterification for evaluation as biodiesel fuels. Camelina oil contained high percentages of linolenic (32.6 wt.%), linoleic (19.6 wt.%), and oleic (18.6 wt.%) acids. Consequently, camelina oil methyl and ethyl esters (CSME and CSEE) exhibited poor oxidative stabilities and high iodine values versus methyl esters prepared from canola, palm, and soybean oils (CME, PME, and SME). Other fuel properties of CSME and CSEE were similar to CME, PME, and SME, such as low temperature operability, acid value, cetane number, kinematic viscosity, lubricity, sulfur and phosphorous contents, as well as surface tension. As blend components in ultra low-sulfur diesel fuel, CSME and CSEE were essentially indistinguishable from SME and soybean oil ethyl ester blends with regard to low temperature operability, kinematic viscosity, lubricity, and surface tension.

The dual-simulation scheme was developed to consider different time scales between a newly developed surface model: Dynamic Agricultural Non-point Source Assessment Tool (DANSAT), and existing groundwater models; a three-dimensional finite-difference groundwater flow model (MODFLOW) and a modular three-dimensional transport model (MT3D). A distributed and physically based DANSAT predicts the movement of water and pesticides in runoff and in leachate at a watershed scale. MODFLOW and MT3D simulate groundwater and pesticide movement in the saturated zone. Only the hydrology component of the linked system was evaluated on the QN2 subwatershed in the Nomini Creek watershed located in the Coastal Plain of Virginia mainly due to lack of observed data for MT3D calibration. The same spatial scale was used for both surface and groundwater models while different time scales were used because surface runoff occurs more quickly than groundwater flow. DANSAT and MODFLOW were separately calibrated using the integrated GW approach which uses own lumped baseflow components in DANSAT, and using the steady-state mode in MODFLOW, respectively. Then the linked system was applied to QN2 based on the parameters selected for DANSAT and MODFLOW to simulate time-dependent interactions on the entire system. The linked approach was better than the integrated approach for predicting the temporal trends of monthly runoff by improving the monthly Nash-Sutcliffe efficiency index from 0.53 to 0.60. The proposed linked approach will be useful for evaluating the impacts of agricultural BMPs on the entire SW-GW system by providing spatial distribution and temporal changes in groundwater table elevation and enhancing the reliability of calibrated parameter sets.

S.J. Darbyshire] is adapted to the diverse growing conditions of humid, temperate agro-ecosystems. A mutualistic endophytic symbiont (Neotyphodium coenophialum, [Morgan-Jones et Gams] Glenn, Bacon, and Hanlin) contributes to this resilience, but at the same time compromises grazing livestock health. Novel endophytes that do not produce ergo-alkaloids were developed to circumvent livestock health issues, but the response of novel associations to site conditions and management practices, such as partial shade and repeated defoliation, is unclear. We conducted a field experiment with tall fescue to determine if carbon isotope discrimination ( Delta ) could be used to characterize host-endophyte association responses to site and management. Plants infected with either the native or novel non-ergogenic endophyte, or that were endophyte free were clipped to typical pasture (5 cm) or silvopasture (10 cm) residual sward heights each time mean canopy height reached 20 cm. The Delta of tall fescue was inversely related to light availability. Greater variation in Delta occurred when plants were clipped to a 5 rather than a 10 cm residue height. This trend persisted throughout the growing season and was similar whether Delta was expressed relative to potential evapotranspiration (ET sub(o)), leaf dry matter content (LDMC) or an index of herbage nutritive value (expressed as energy relative to crude protein). Host-endophyte association did not affect Delta . This might be attributable to relatively mild growing conditions occurring in the central Appalachian region of the USA, irrespective of site conditions, or the minimal cost of hosting endophyte. Carbon isotope discrimination responses for tall fescue agree with previous observations on Delta and light availability, and might be a useful means to assess silvopastoral management practices.

Steers (n = 603; 261 A+/- 32 kg) were fed in eight pens (15 X 150 m) of 75 to 77 steers per pen. Two consecutive experiments were conducted with WDGS-one in which the corn source fed with WDGS was high-moisture and one in which WDGS was fed with dry-rolled corn. We compared odorants (volatile fatty acids [VFAs], aromatic compounds, NH sub(3), H sub(2)S) and persistence of Escherichia coli in feedlot manure slurries stored from 0 to 28 d. From both experiments, manure collected from cattle fed 40% WDGS had lower (P < 0.05) total VFAs, including acetate, propionate, and butyrate, all of which continued to be lower to 28 d. However, these slurries had greater concentrations (P < 0.05) of branched-chained VFAs (isobutyrate and isovalerate), especially after 14 d of incubations. Similarly, p-cresol and skatole concentrations tended to be greater in slurries originating from 40% WDGS diets and increased with incubation time. Indole was initially greater in the slurries from 40% WDGS diets; however, it was metabolized by microbes during incubation. Manure slurries from the 40% WDGS diets had greater quantities of H sub(2)S, NH sub(3), and P (P < 0.05). Levels of E. coli in 0 and 40% WDGS manure slurries were similar when high-moisture corn was used in the diets. However, when dry-rolled corn was used, E. coli persisted longer in 40% WDGS manure slurries in comparison to 0% WDGS. Results here support earlier studies that suggest feeding WDGS increases odor emissions, N loss, E. coli survival, and surface water contamination due to greater potential P runoff.

To evaluate crop safety and environmental risks with the replant fumigation, four field experiments were performed over 2 yr to examine 1,3-D and CP lateral movement away from the treated fields. Shank injection with or without a virtually impermeable film (VIF) was used in two vineyard fumigation experiments, and spot drip application without tarp cover was used in two orchard experiments. Results showed that 1,3-D and CP gases moved laterally to 6 m from the treated fields when the fumigants were applied by shank injection. The maximum 1,3-D or CP soil gas concentration at 6 m was approximately 10 ng cm super(-3) when the fumigated plot was not cover with a tarp. With VIF, the measured maximum concentration increased to approximately 100 ng cm super(-3). In the spot drip application, maximum 1,3-D and CP gas concentrations reached approximately 100 ng cm super(-3) but at 1.5 m radial distance from the point of fumigant injection.

However, there are concerns regarding manure's effect on water quality. In 2003 and 2004, we measured sediment, NO sub(3)-N, NH sub(4)-N, K, dissolved reactive P (DRP), and total P (TP) concentrations in runoff from furrow irrigated field plots (6-7 irrigations yr super(-1)) cropped to corn (Zea mays L.) in the semiarid climate of southern Idaho. Annual treatments included 13 (Year 1) and 34 Mg ha super(-1) (Year 2) stockpiled dairy manure (M); 78 (Year 1) and 195 kg N ha super(-1) (Year 2) inorganic N fertilizer (F); or control-no amendment (C). Available N in manure applied each year was similar to amounts applied in fertilizer. Constituent concentrations (mg L super(-1)) in runoff ranged widely among all treatments: sediment, 10 to 50,000; NO sub(3)-N, 0 to 4.07; NH sub(4)-N, 0 to 2.28; K, 3.6 to 46.4; DRP, 0.02 to 14.3; and TP, 0.03 to 41.5. Over both years, fertilizer and manure treatments increased irrigation mean values (averaged across irrigations) for NO sub(3)-N runoff concentrations (M = 0.30, F = 0.26, C = 0.21 mg L super(-1)) and mass losses (M = 0.50, F = 0.42, C = 0.33 kg ha super(-1)) relative to the control. Over both years, the manure treatment also increased mean irrigation runoff concentrations of DRP (M = 0.19, F = 0.09, C = 0.08 mg L super(-1)) and K (M = 1.13, F = 0.79, C = 0.62 mg L super(-1)) compared with fertilizer and control plots. Average DRP and K runoff mass losses were 2.0 to 2.4 times greater in manure treatments than in control plots. Neither F or M affected season-long cumulative infiltration. Runoff DRP and inorganic-N losses appeared to be influenced more by the timing of the amendment application and environmental conditions than by the quantity of nutrients applied. Nutrient additions to furrow irrigated soils, whether from fertilizer or manure, can potentially increase nutrient losses in irrigation runoff, with the degree of impact depending on the nutrient, amount, and timing of application and whether inorganic fertilizer or manure was applied.

In the U.S. Mid-South it is applied from April to September to fertilize grass hay in spray-irrigated fields. Lagoon levels of nutrients and bacteria, and soil levels of nutrients have been documented, but little was known of effluent bacterial levels in soil. The present study examined levels of selected effluent bacteria and nutrients in soils inside and outside spray fields after >15 yr of effluent irrigation. Samples were collected February to March 2009 from contiguous soils spanning adjacent irrigated and nonirrigated areas. Separate soil cores for bacterial and nutrient tests were collected in pairs <10 cm apart. Five cores each were collected at 15-m intervals and combined, respectively, to comprise inside and outside samples from each of 20 soils (four each from five farms/spray fields). Analyses of data combined across all soils showed higher pH and Mehlich-3-extractable (M3-) P, Mg, K, Na, Cu, and Zn inside than outside spray fields, while total N, total C, M3-Ca, and M3-Mn did not differ. Bacterial levels were higher inside than outside spray fields for heterotrophic plate counts, thermotolerant coliforms, Staphylococcus spp., and Clostridium perfringens, but levels of Escherichia coli and Enterococcus spp. were not different. Cultural presence/absence tests for three pathogens (Listeria spp., Campylobacter spp., and Salmonella spp.) detected only Listeria spp., which did not differ inside (23% positive samples) and outside (28% positive). Molecular tests detected all three pathogens at low levels that were not different inside and outside. We found no evidence of cumulative buildup of Campylobacter spp., Listeria spp., or Salmonella spp. in spray field soils.

We test the ability of the Root Zone Water Quality Model (RZWQM) to simulate watershed-scale variability due to the LSNT, and we use the optimized model to simulate long-term field N dynamics under related conditions. Autoregressive techniques and the automatic parameter calibration program PEST were used to show that RZWQM simulates significantly lower nitrate concentration in discharge from LSNT treatments compared with areas receiving fall N fertilizer applications within the tile-drained Walnut Creek, Iowa, watershed (>5 mg N L super(-1) difference for the third year of the treatment, 1999). This result is similar to field-measured data from a paired watershed experiment. A statistical model we developed using RZWQM simulations from 1970 to 2005 shows that early-season precipitation and early-season temperature account for 90% of the interannual variation in LSNT-based fertilizer N rates. Long-term simulations with similar average N application rates for corn (Zea mays L.) (151 kg N ha super(-1)) show annual average N loss in tile flow of 20.4, 22.2, and 27.3 kg N ha super(-1) for LSNT, single spring, and single fall N applications. These results suggest that (i) RZWQM is a promising tool to accurately estimate the water quality effects of LSNT; (ii) the majority of N loss difference between LSNT and fall applications is because more N remains in the root zone for crop uptake; and (iii) year-to-year LSNT-based N rate differences are mainly due to variation in early-season precipitation and temperature.

Although these lagoons were once thought to be relatively simple, their physical, chemical, and biological processes are very complex. This study of anaerobic lagoons had two objectives: (i) to quantify denitrification enzyme activity (DEA) and (ii) to evaluate the influence of lagoon characteristics on the DEA. The DEA was measured by the acetylene inhibition method. Wastewater samples and physical and chemical measurements were taken from the wastewater column of nine anaerobic swine lagoons from May 2006 to May 2009. These lagoons were typical for anaerobic swine lagoons in the Carolinas relative to their size, operation, and chemical and physical characteristics. Their mean value for DEA was 87 mg N sub(2)O-N m super(-3) d super(-1). In a lagoon with 2-m depth, this rate of DEA would be compatible with 1.74 kg N ha super(-1) d super(-1) loss. When nonlimiting nitrate was added, the highest DEA was compatible with 4.38 kg N ha super(-1) d super(-1) loss. Using stepwise regression for this treatment, the lagoon characteristics (i.e., soluble organic carbon, total nitrogen, temperature, and NO sub(3)-N) provided a final step model R super(2) of 0.69. Nitrous oxide from incomplete denitrification was not a significant part of the system nitrogen balance. Although alternate pathways of denitrification may exist within or beneath the wastewater column, this paper documents the lack of sufficient denitrification enzyme activity within the wastewater column of these anaerobic lagoons to support large N sub(2) gas losses via classical nitrification and denitrification.

However, the relative importance of sediments as bacterial habitats and as a source of water-borne fecal coliforms and E. coli has not been recognized until recently, when a large number of publications have shown that in many cases the resuspension of sediment, rather then runoff from surrounding lands, can create elevated E. coli concentrations in water. This review is an attempt to develop the first comprehensive single source of existing information about fecal coliforms and E. coli in sediments and adjacent soils and to outline the knowledge gaps and research needs. The authors summarize available information on variability and environmental correlations of E. coli and FC concentrations in sediments, genetic diversity of E. coli in sediments, survival of E. coli and FC in sediments, release with resuspended sediment and settling of E. coli and FC, modeling of sediment effects on fate and transport of E. coli in surface waters, and implications for monitoring and management of microbiological water quality. The demonstrated role of pathogenic E. coli strains in food and water quality challenges reinforces the need in better understanding ecological and hydrological factors that affect functioning of sediments as E. coli reservoirs.

Using a newly developed robust mRNA reference and a master equation unifying gene expression data analyses, we investigated comparative quantitative transcription dynamics of 175 genes selected from previous studies for an ethanol-tolerant yeast and its closely related parental strain. Results: A highly fitted master equation was established and applied for quantitative gene expression analyses using pathway-based qRT-PCR array assays. The ethanol-tolerant Y-50316 displayed significantly enriched background of mRNA abundance for at least 35 genes without ethanol challenge compared with its parental strain Y-50049. Under the ethanol challenge, the tolerant Y-50316 responded in consistent expressions over time for numerous genes belonging to groups of heat shock proteins, trehalose metabolism, glycolysis, pentose phosphate pathway, fatty acid metabolism, amino acid biosynthesis, pleiotropic drug resistance gene family and transcription factors. The parental strain showed repressed expressions for many genes and was unable to withstand the ethanol stress and establish a viable culture and fermentation. The distinct expression dynamics between the two strains and their close association with cell growth, viability and ethanol fermentation profiles distinguished the tolerance-response from the stress-response in yeast under the ethanol challenge. At least 82 genes were identified as candidate and key genes for ethanol-tolerance and subsequent fermentation under the stress. Among which, 36 genes were newly recognized by the present study. Most of the ethanol-tolerance candidate genes were found to share protein binding motifs of transcription factors Msn4p/Msn2p, Yap1p, Hsf1p and Pdr1p/Pdr3p. Conclusion: Enriched background of transcription abundance and enhanced expressions of ethanol-tolerance genes associated with heat shock proteins, trehalose-glycolysis-pentose phosphate pathways and PDR gene family are accountable for the tolerant yeast to withstand the ethanol stress, maintain active metabolisms, and complete ethanol fermentation under the ethanol stress. Transcription factor Msn4p appeared to be a key regulator of gene interactions for ethanol-tolerance in the tolerant yeast Y-50316.

The quantification of soil erosion was performed on hill slope scale (2.20 m) for three different land use types: hayfields, pastures with dwarf shrubs and pastures without dwarf shrubs with three replicates each. Erosion rates during growing season were measured with sediment traps between June 2006 and November 2007. Long-term soil erosion rates were estimated based on Cs-137 redistribution. In addition, soil moisture and surface flow were recorded during the growing season in the field and compared to model output. We chose the WEPP model (Water Erosion Prediction Project) to simulate soil erosion during the growing season. Model parameters were determined in the field (slope, plant species, fractional vegetation cover, initial saturation level), by laboratory analyses (grain size, organic matter) and by literature study. The WEPP model simulates sheet erosion processes (interrill and splash erosion processes, please note that no rill erosion occurs at our sites). Model output resulted in considerable smaller values than the measured erosion rates with sediment traps for the same period. We attribute the differences to observed random gravity driven erosion of soil conglomerates. The Cs-137 measurements deliver substantially higher mean annual erosion rates, which are most likely connected to snow cover related processes such as snow gliding and avalanche activities.

Previously, we characterized the phiC31 catalytic activity and modes of action in the fission yeast Schizosaccharomyces pombe. Results: In this work, the phiC31 recombinase gene was placed under the control of the Arabidopsis OXS3 promoter and introduced into Arabidopsis harboring a chromosomally integrated attB and attP-flanked target sequence. The phiC31 recombinase excised the attB and attP-flanked DNA, and the excision event was detected in subsequent generations in the absence of the phiC31 gene, indicating germinal transmission was possible. We further verified that the genomic excision was conservative and that introduction of a functional recombinase can be achieved through secondary transformation as well as manual crossing. Conclusion: The phiC31 system performs site-specific recombination in germinal tissue, a prerequisite for generating stable lines with unwanted DNA removed. The precise site-specific deletion by phiC31 in planta demonstrates that the recombinase can be used to remove selectable markers or other introduced transgenes that are no longer desired and therefore can be a useful tool for genome engineering in plants.

However, most information about the microbial populations in the gut of livestock species has not been quantitative. In the present study, we utilized a new molecular method, bacterial tag-encoded FLX amplicon pyrosequencing (bTEFAP) that can perform diversity analyses of gastrointestinal bacterial populations. In the present study, cattle (n = 6) were fed a basal feedlot diet and were subsequently randomly assigned to 1 of 3 diets (n = 2 cows per diet). In each diet, 0, 25, or 50% of the concentrate portion of the ration was replaced with dried distillers grain (DDGS). Ruminal and fecal bacterial populations were different when animals were fed DDGS compared with controls; ruminal and fecal Firmicute:Bacteroidetes ratios were smaller (P = 0.07) in the 25 and 50% DDG diets compared with controls. Ruminal pH was decreased (P < 0.05) in ruminal fluid from cattle fed diets containing 50% compared with 0% DDGS. Using bTEFAP, the normal microbiota of cattle were examined using modern molecular methods to understand how diets affect gastrointestinal ecology and the gastrointestinal contribution of the microbiome to animal health and production.

Moreover, groundwaters that are contaminated with atrazine often contain nitrate as well. Nitrate interferes with the biological degradation of atrazine and makes it more difficult to use in situ biological methods to remediate atrazine contaminated groundwater. To solve this problem we used two reactors in sequence as models of in situ biobarriers; the first was a vegetable-oil-based denitrifying biobarrier and the second an aerobic reactor that oxygenated the denitrifying reactor's effluent. The reactors were inoculated with an atrazine-degrading microbial consortium and supplied with water containing 5mgl super(-1) nitrate-N and 3mgl super(-1) atrazine. Our hypothesis was that the denitrifying barrier would remove nitrate from the flowing water and that the downstream reaction would remove atrazine. Our hypothesis proved correct; the two reactor system removed 99.9% of the atrazine during the final 30weeks of the study. The denitrifying barrier removed ~98% of the nitrate and ~30% of the atrazine while the aerobic reactor removed ~70% of the initial atrazine. The system continued to work when the amount of nitrate-N in the influent water was increased to 50mgl super(-1). A mercury poisoning study blocked the degradation of atrazine indicating that biological processes were involved. An in situ denitrifying barrier coupled with an air injection system or other oxygenation process might be used to remove both nitrate and atrazine from contaminated groundwater or to protect groundwater from an atrazine spill.

Schott AN - 1017981898; 16752875 AB - Colocasia esculenta (L.) Schott (taro) is a staple food crop in many developing nations of Asia, Africa and the Pacific. A member of family Araceae, taro is an ancient crop grown throughout the humid tropics for its edible corms, leaves and petioles as well as for its traditional uses. In the Pacific, the crop has attained supreme importance in the diets of the inhabitants. A study was undertaken to develop an economically feasible, efficient, rapid and reproducible regeneration protocol for taro. Taro plants were regenerated via somatic embryogenesis and organogenesis from shoot part (10-15mm) adjacent to the corm and shoot meristem, respectively. Murashige and Skoog, 1962 (MS) medium was used throughout the study. A two-step protocol (initially on medium augmented with 10 mu M 2,4-dichlorophenoxyacetic acid (2,4-D) and 2 mu M thidiazuron (TDZ) followed by a culture phase with 5 mu M TDZ) was used to regenerate somatic embryos. Embryos at various developmental stages (globular, heart and torpedo shaped) were observed and confirmed through histological studies. In organogenesis, cultures were initiated on medium augmented with 2 mu M TDZ and then transferred on medium with 5 mu M TDZ. For further growth and subsequent multiplication, shoots were transferred on medium augmented with 5 mu M indole-3-acetic acid (IAA) and 7.5 mu M 6-benzylaminopurine (BAP). The number of multiple shoots produced from each explant after two subcultures varied from 40 to 50. MS medium augmented with 2 mu M IAA was used for rooting. Mature plants were recovered from both somatic embryos as well as from induced shoots. A 12-h photoperiod with a temperature of 28 degree C day and 24 degree C night, light intensity of 40 mu mol m-2 s-1, and 55 plus or minus 5% relative humidity were maintained for multiplication. Rooted plants were transferred to soil: vermiculate (1:1, v/v) mixture in pots and acclimatized with 100% survival rate. Fully acclimatized plants were planted in the field.

To extend our understanding of the genetic relationship between Cronobacter sakazakii BAA-894 and the other species of this genus, microarray-based comparative genomic indexing (CGI) was undertaken to determine the presence/absence of genes identified in the former sequenced genome and to compare 276 selected open reading frames within the different Cronobacter strains. Seventy-eight Cronobacter strains (60 C. sakazakii, 8 C. malonaticus, 5 C. dublinensis, 2 C. muytjensii, 1 C. turicensis, 1 C. genomospecies 1, and 1 Cronobacter sp.) representing clinical and environmental isolates from various geographical locations were investigated. Hierarchical clustering of the CGI data showed that the species grouped as clusters. The 5 C. dublinensis and 2 C. muytjensii strains examined formed distinct species clusters. Moreover, all of the C. sakazakiiand 3 of 8 C. malonaticus strains formed a large cluster. The remaining C. malonaticus strains formed a sub-group within a larger cluster that also contained C. turicensis, C. genomospecies 1, and an unknown Cronobacter sp. Cronobacter sakazakii and 3 of 8 C. malonaticus strains could be distinguished from the others within the collection by the presence of 10 fimbrial related genes. Similarly, capsule and/or lipopolysaccharide (LPS) related glycosyltransferases differentiated several of the C. sakazakii strains from each other.

AN - 21163203; 11186725 AB - The phytotoxicity of Se(IV) was determined through root and shoot growth inhibition, biomass (dry (DM), fresh (FM)) production, water content, photosynthetic pigment (chlorophyll a, chlorophyll b and carotenoids) levels and Se accumulation in the roots and shoots. The sensitivities of monocotyledonae (Hordeum vulgare, Triticum aestivum) and dicotyledonae plants (Sinapis alba, Brassica napus) were also compared. Except for H. vulgare, Se(IV) inhibited root growth more than shoot growth. As for biomass production, Se reduced both FM and DM of all studied plants' roots. Although in shoots FM was decreased with increased Se concentration, DM was reduced only in monocotyledonae plants (H. vulgare, T. aestivum). No significant differences between roots and shoots were confirmed for the DM/FM relationship, except for S. alba seedlings. In all of the tested plants, except for B. napus, chlorophyll b was the strongest reduced pigment. Accumulation of Se was higher in the roots than in the shoots of all studied plants. Selenium concentration in the roots was at least 3-times higher than that in controls. Se(IV) accumulation in the shoots was not significantly different from that in controls. The exception was confirmed only for B. napus (87mgSe(IV)l super(-) super(1)) and T. aestivum (36mgSe(IV)l super(-) super(1)).

The goals of the conference were to explore how the outcomes of host-parasite interactions depend on variation across individuals, their parasites and the environment in which they both find themselves. Central themes were the inherent costs of mounting an immune response, the ability of some organisms to pre-empt infection by "priming" their immune systems, the fact that parasites learn to evade immune responses over time and the use of theory to predict when diseases will get out of hand. Many of the systems presented had clear impacts on human health, agriculture or the maintenance of complex ecosystems. There was common ground throughout in developing methodologies and embracing what one of the organizers termed the "interactome" between hosts and those which would exploit them.

A basal purified diet (35% protein and 3.4kcal DE/g) supplemented with 6, 10 and 14% of 1:1 mixture of corn oil and menhaden fish oil was each supplemented with 50, 100 and 200mg vitamin E/kg. Each diet was fed to Nile tilapia in triplicate aquaria for 12weeks. Weight gain, feed intake and survival were not affected by dietary levels of either lipid or vitamin E. Feed efficiency in fish fed 14% lipid diets was significantly lower than that fed 6% dietary lipid but these did not differ from that of the 10% dietary lipid diet. These variables were not affected by dietary vitamin E levels. Whole body lipid significantly increased in fish fed 14% lipid diets and 100mg/kg vitamin E diets. Liver a-tocopherol levels were reflective of dietary levels of vitamin E. Increasing dietary levels of lipid to 14%, however, significantly decreased liver concentration of a-tocopherol. Hematological parameters and hepatosomatic indices were not affected by dietary treatments. Serum protein significantly increased in fish fed 14% lipid diets but was not affected by supplemental levels of vitamin E. Lysozyme activity was not affected by dietary lipid levels but significantly increased in fish fed 200mg vitamin E diets. Alternative complement activity significantly decreased in fish fed 10 or 14% dietary lipids but increased when dietary vitamin E levels was increased to 100 or 200mg. Dietary lipid and vitamin E levels had no effect on the resistance of Nile tilapia to S. iniae infection and on antibody titer against that bacterium.

However, few studies provide a complete analysis of the factors and interactions that affect carbon dynamics over a large landscape. This study examines how changes in atmospheric composition (CO2, O3 and N deposition), climate and land-use affected carbon dynamics and sequestration in Mid-Atlantic temperate forests during the 20th century. We modified and applied the PnET-CN model, a well established process-based ecosystem model with a strong foundation of ecosystem knowledge from experimental studies. We validated the model results using the U.S. Forest Inventory and Analysis (FIA) data. Our results suggest that chronic changes in atmospheric chemistry over the past century markedly affected carbon dynamics and sequestration in Mid-Atlantic temperate forests, while climate change only had a minor impact although inter-annual climatic variability had a far more substantial effect. The NPP response to a century of chronic change in atmospheric composition at the regional scale was an increase of 29%, of which, 14% was from elevated CO2, 17% from N deposition, 6% from the interaction between CO2 and N deposition, and minus 8% from tropospheric ozone. Climate change increased NPP by only 4%. Disturbed forests had 6% lower NPP than undisturbed forests after seven decades. Regrowing forests after harvesting and natural disturbances had much greater capacity for sequestering carbon than undisturbed old-growth forests even though the newer forests had slightly lower net primary production (NPP). The modeling results indicated that N deposition was a stronger force than elevated CO2 for increasing NPP and fast turnover tissues, while elevated CO2 favored more sustainable carbon storage and sequestration. The model results are consistent with various experiments and observations and demonstrate a powerful approach to integrate and expand our knowledge of complex interactive effects of multiple environmental changes on forest carbon dynamics.

14338777 AB - Soil surface application of dissolved linear polyacrylamide (PAM) of high molecular weight (MW) can mitigate seal formation, runoff, and erosion, especially when added with a source of electrolytes (e.g. gypsum). Practical difficulties associated with PAM solution application prohibited commercial use of PAM in dryland farming. An alternative practice of spreading dry granular PAM with high MW on the soil surface has been ineffective in reducing runoff while effectively reducing erosion. The objective of this study was to investigate the mechanism by which granular PAM (20 kg/ha), with moderate (2 10 super(5) Da) or high (1.2 10 super(7) Da) MW, mixed with phosphogypsum (PG) (4 Mg/ha) affects infiltration rate, runoff, and erosion. Five smectitic soils, treated with PAM and PG, were exposed to simulated rainfall of deionised water in the laboratory. Both dry PAMs, mixed with PG, increased final infiltration rate (3-5 times) and reduced erosion (2-4 times) relative to the control (no amendments). Whereas the polymers' effects on the infiltration rate and runoff relative to each other were inconsistent, PAM with moderate MW was consistently more effective in reducing soil loss than PAM with high MW. For example, in the sandy clay soil, soil losses were reduced from 840 g/m super(2), in the control, to 570 and 370 g/m super(2) for the high and moderate MW PAM treatment, respectively. This greater capacity to control soil erosion was ascribed to the lower viscosity of the soil surface solution following dissolution of dry PAM granules in the case of moderate MW PAM, leading to more uniform, effective treatment of soil aggregates at the soil surface by the polymer.

AN - 733682548; 19950998 AB - A statistically based survey of dioxins and dioxin-like compounds in domestic meat and poultry was conducted by the U.S. Department of Agriculture (USDA) from September 2007 to September 2008. Seventeen toxic polychlorinated dibenzo-p-dioxins and dibenzofurans (PCDD/Fs) and four non-ortho-polychlorinated biphenyls (no-PCBs) were measured in 510 beef (steer/heifer), market hog, young turkey, and young chicken samples. The results of the survey showed the sum of PCDD/F and no-PCB toxic equivalencies (sum-TEQs) ranging from not detected to 4.5 pg/g of lipid. Mean sum-TEQ levels for beef, turkey, chicken, and pork were 0.66, 0.61, 0.17, and 0.16 pg/g of lipid, respectively. To compare the new survey data with data from previous USDA surveys in the mid-1990s and 2002-2003, TEQs from all data sets were calculated using the most recent 2005 toxic equivalency factors (TEFs). The results of the recalculation on the older survey data was a small increase (4-13%) in mean TEQs for the mid-1990s data, which initially used pre-1994 TEFs, and a small decrease (2-4%) for the 2002-2003 data, which initially used 1998 TEFs. A comparison of the three surveys indicates declining TEQ trends in all slaughter classes over the 10 year period; however, the congener patterns remain relatively constant between 2002 and 2008, indicating similar animal exposures to dioxins and dioxin-like compounds during these time periods. Several samples from the 2008 survey with the highest TEQ values are undergoing follow-up investigations to determine possible sources that may be contributing to these levels.

11300295 AB - Across the western United States, warm-season grasslands are being invaded by the exotic perennial grass, Eragrostis lehmanniana (Lehmann lovegrass). The objective of this study was to quantify the change in surface water balance, particularly the evaporation from bare soil, associated with E. lehmanniana invasion. Following a protracted drought, the Kendall grassland in the USDA-ARS Walnut Gulch Experimental Watershed in southeast Arizona transitioned from a diverse, native bunchgrass community to one dominated by E. lehmanniana. A network of 20 microlysimeters was deployed to measure daily soil evaporation (E sub(D)) in 2005 and again in 2007 (pre- and post-invasion years, respectively). This was supported with continuous measurements of evapotranspiration (ET), precipitation (P), runoff (R), surface soil moisture ( psi ), and solar irradiance (L) at Kendall from 2002 to the present. An empirical equation was developed to derive E sub(D) based on psi measured midday at 5cm depth and average daily L. This was applied to years 2002-2007 during the vegetation growing season (June through October). Results confirmed that total ET over the growing season (ET sub(S)) was a function of season-long infiltration (where I sub(S)=P sub(S)-R sub(S)) for growing seasons over the past decade regardless of vegetation type, where ET sub(S)/I sub(S) was slightly greater than one in years drier than average and close to one in years with greater than average infiltration. For years of similar precipitation patterns and ET sub(S)/I sub(S), the contribution of evaporation E to ET for the growing season (E sub(S)/ET sub(S)) doubled with the invasion of E. lehmanniana. Variation in E sub(S)/ET sub(S) ranged from 0.26 to 0.60 for years 2002-2007, where variation was related primarily to inter-annual precipitation patterns in the early season and to distinctive vegetation transformation in the middle season. These results are a first step toward understanding the ecohydrological consequences of E. lehmanniana invasion in semiarid grasslands.

Norman's involvement in the development of several key instruments for biophysical measurement AN - 21100830; 11300298 AB - If you have ever used a quantum sensor, or measured the LAI of a plant canopy, or lugged around a portable photosynthesis system, then you are likely the beneficiary of just some of John Norman's work in instrumentation. In his nearly 40-year career of trying to understand plants and their environment through modeling and measurements, John's boundless creativity and enthusiasm have never let lack of available instrumentation stop him for long. He leaves behind an impressive wake of gadgets and devices. Most served their purpose, and provided the missing information being sought. Some of his devices have gone on to world-wide success, while others are found only in the dust of former students' memories. John's legacy, however, is clear, and goes well beyond instrumentation: he is a joyful, creative resource, as all who have had the privilege of knowing him can attest.

Numerous models have been developed using remote sensing, which permits spatially distributed mapping of the surface energy balance over large areas. This study compares flux maps over a relatively simple agricultural landscape in central Iowa, comprised of soybean and corn fields, generated with three different remote sensing-based surface energy balance models: the Two-Source Energy Balance (TSEB) model, Mapping EvapoTranspiration at high Resolution using Internalized Calibration (METRIC), and the Trapezoid Interpolation Model (TIM). The three models have different levels of complexity and input requirements, but all have operational capabilities. METRIC and TIM make use of the remotely sensed surface temperature-vegetation cover relation to define key model variables linked to wet and dry hydrologic extremes, while TSEB uses these remotely sensed inputs to define component soil and canopy temperatures, aerodynamic resistances, and fluxes. The models were run using Landsat imagery collected during the Soil Moisture Atmosphere Coupling Experiment (SMACEX) in 2002 and model results were compared with observations from a network of flux towers deployed within the study area. While TSEB and METRIC yielded similar and reasonable agreement with measured heat fluxes, with root-mean-square errors (RMSE) of ~50-75W/m super(2), errors for TIM exceeded 100W/m super(2). Despite the good agreement between TSEB and METRIC at discrete locations sampled by the flux towers, a spatial intercomparison of gridded model output (i.e., comparing output on a pixel-by-pixel basis) revealed significant discrepancies in modeled turbulent heat flux patterns that were largely correlated with vegetation density. Generally, the largest discrepancies, primarily a bias in H, between these two models occurred in areas with partial vegetation cover and a leaf area index (LAI)<2.0. Adjustment of the minimum LE assumed for the hot/dry hydrologic extreme condition in METRIC reduced the bias in H between METRIC and TSEB, but caused a significant increase in bias in LE between the models. Spatial intercomparison of modeled flux patterns over a variety of landscapes will be required to better assess uncertainties in remote sensing surface energy balance models, and to work toward an improved hybrid modeling system.

However, the specter of massive biofuel production has raised other worries, specifically that by displacing food production it will lead to higher food prices, increased incidence of famine, and acceleration of undesirable land use change. One proposed solution is to increase the annual net primary productivity of the existing agricultural land base, so that it can sustainably produce both food and biofuel feedstocks. This might be possible in corn and soybean production regions through the use of winter cover crops, but the biophysical feasibility of this has not been systematically explored. We developed a model for this purpose that simulates the potential biomass production and water use of winter rye in continuous corn and corn-soybean rotations. The input data requirements represent an attempt to balance the demands of a physically and physiologically defensible simulation with the need for broad applicability in space and time. The necessary meteorological data are obtainable from standard agricultural weather stations, and the required management data are simply planting dates and harvest dates for corn and soybeans. Physiological parameters for rye were taken from the literature, supplemented by experimental data specifically collected for this project. The model was run for a number of growing seasons for 8 locations across the Midwestern USA. Results indicate potential rye biomass production of 1-8Mgha super(-) super(1), with the lowest yields at the more northern sites, where both PAR and degree-days are limited in the interval between fall corn harvest and spring corn or soybean planting. At all sites rye yields are substantially greater when the following crop is soybean rather than corn, since soybean is planted later. Not surprisingly, soil moisture depletion is most likely in years and sites where rye biomass production is greatest. Consistent production of both food and biomass from corn/winter rye/soybean systems will probably require irrigation in many areas and additional N fertilizer, creating possible environmental concerns. Rye growth limitations in the northern portion of the corn belt may be partially mitigated with aerial seeding of rye into standing corn.

However, it failed to establish in the southern and western portions of the saltcedar infestation, creating the need to test additional populations of the beetle from other areas within its region of origin. The host specificity of seven Eurasian populations of D. elongata was evaluated by testing larval development and adult ovipositional preference on a variety of non-target agricultural, ornamental and native plants, with emphasis placed on native Frankenia spp. (Frankeniaceae), which were shown to be laboratory hosts in previous tests. No larvae survived on any of the non-target test plants except for Frankenia spp., where survival to the adult stage ranged between 15% and 92%, and was often not significantly different from survival on Tamarix controls. Adult Diorhabda from Crete laid significantly more eggs on Tamarix ramosissima Ledebour than on Frankenia spp. in a multiple-choice oviposition test but showed very little discrimination between Tamarix and Frankenia species in a no-choice test. In paired-choice tests, all seven Diorhabda populations laid significantly more eggs on T. ramosissima than Frankenia salina (Molina) I.M. Johnston. However, the percentage of total eggs laid on F. salina ranged from 0.8% to 15.7%, suggesting that some utilization of this native plant might occur in the field, despite the presence of a preferred host plant. Significant differences were found between some Diorhabda populations in the percent of total eggs laid on F. salina, indicating a variable degree of risk to these non-target plants.

Additionally, we conducted a phylogenetic characterization of the nematode's symbiotic bacterium. In laboratory experiments, we compared H. georgiana to other entomopathogenic nematodes for virulence, environmental tolerance (to heat, desiccation, and cold), and host seeking ability. Virulence assays targeted Acheta domesticus, Agrotis ipsilon, Diaprepes abbreviatus, Musca domestica, Plodia interpunctella, Solenopsis invicta, and Tenebrio molitor. Each assay included H. georgiana and five or six of the following species: Heterorhabditis floridensis, Heterorhabditis indica, Heterorhabditis mexicana, Steinernema carpocapsae, Steinernema feltiae, Steinernema rarum, and Steinernema riobrave. Environmental tolerance assays included Heterorhabditis bacteriophora, H. georgiana, H. indica, S. carpocapsae, S. feltiae, and S. riobrave (except cold tolerance did not include S. carpocapsae or S. riobrave). Host seeking ability was assessed in H. bacteriophora, H. georgiana, S. carpocapsae, and Steinernema glaseri, all of which showed positive orientation to the host with S. glaseri having greater movement toward the host than S. carpocapsae (and the heterorhabditids being intermediate). Temperature range data (tested at 10, 13, 17, 25, 30 and 35 degree C) indicated that H. georgiana can infect Galleria mellonella between 13 and 35 degree C (with higher infection at 17-30 degree C), and could reproduce between 17 and 30 degree C (with higher nematode yields at 25 degree C). Compared with other nematode species, H. georgiana expressed low or intermediate capabilities in all virulence and environmental tolerance assays indicating a relatively low biocontrol potential. Some novel observations resulted from comparisons among other species tested. In virulence assays, H. indica caused the highest mortality in P. interpunctella followed by S. riobrave; S. carpocapsae caused the highest mortality in A. domesticus followed by H. indica; and S. riobrave was the most virulent nematode to S. invicta. In cold tolerance, S. feltiae exhibited superior ability to cause mortality in G. mellonella (100%) at 10 degree C, yet H. bacteriophora and H. georgiana exhibited the ability to produce attenuated infections at 10 degree C, i.e., the infections resumed and produced mortality at 25 degree C. In contrast, H. indica did not show an ability to cause attenuated infections. Based on the phylogenetic analysis, the bacterium associated with H. georgiana was identified as Photorhabdus luminescens akhurstii.

Yet, in the 50 years since the integrated control concept [ICC] [Stern, V.M., Smith, R.F., van den Bosch, R., Hagen, K.S., 1959. The integrated control concept. Hilgardia 29, 81-101] was introduced there are few operational programs and even fewer attempts to analyze the mechanisms that allow chemical and biological control to act in concert. The dearth of demonstrable evidence for the ICC has eroded the credibility of biological control and its usage in operational IPM plans. We used in situ life tables within an experimental design to measure and compare the contribution and interaction of biological control and insecticides as tactical components within three pest management systems for Bemisia tabaci (Gennadius) in cotton. Insecticides were the key factor immediately following applications of broad-spectrum materials or one of two selective insect growth regulators (IGRs), and this mortality replaced that provided by natural enemies. Two to six weeks later, however, mortality from natural enemies, primarily predation, in the IGR regimes rebounded to the high levels observed in untreated controls and became the key factor. Mortality from natural enemies remained depressed in the broad-spectrum insecticide regime. Single IGR applications were sufficient to suppress B. tabaci populations throughout the season, while up to five broad-spectrum applications were needed to achieve comparable control. The chemical residual of IGRs was limited to several weeks, demonstrating a key role for mortality from conserved natural enemies that extended the control interval. This "bioresidual" allows for long-term, commercially-acceptable pest suppression following the use of selective insecticides. We provide a rare experimental illustration of integrated control, where chemical and biological controls "augment one another". Our approach and methodology could be applied to demonstrate and validate integrated control in many other systems, addressing a critical need for implementation of biological control in practicing IPM systems.

However, lack of OPGs also generated pleiotropic phenotypes such as reduced motility and slower growth rate under hypoosmotic growth conditions. Whether the observed suboptimal virulence of opg mutants was due to reduced motility was investigated by isolating fully motile revertants of opgGH mutants. Motility revertants remained defective in OPGs synthesis and restitution of motility did not restore mouse virulence. In Escherichia coli, inactivation of rcsB, rcsD, and rcsF lead to restoration of motility in opg mutants, while in Salmonella strains, inactivation of the Rcs pathway is known to attenuate virulence. DNA sequence analysis revealed that except for two silent mutations no other changes in the DNA sequences of Rcs pathway genes were detected in the motility-revertant strain. Moreover, transcripts of all the Rcs phosphorelay pathway genes were detected in opgGH mutants and revertant strain. The data suggest that Salmonella may have distinctive regulatory elements in addition to Rcs phosphorelay genes to rescue motility of opg mutants and affecting also mouse virulence.

Broad-scale forested wetland hydrology has been difficult to study with conventional remote sensing methods. Airborne Light Detection and Ranging (LiDAR) is a new and rapidly developing technology. LiDAR data have mainly been used to derive information on elevation. However, the intensity (amplitude) of the signal has the potential to significantly improve the ability to remotely monitor inundation - an important component of wetland hydrology. A comparison between LiDAR intensity data collected during peak hydrologic expression and detailed in situ data from a series of forested wetlands on the eastern shore of Maryland demonstrate the strong potential of LiDAR intensity data for this application (> 96% overall accuracy). The relative ability of LiDAR intensity data for forest inundation mapping was compared with that of a false color near-infrared aerial photograph collected coincident with the LiDAR intensity (70% overall accuracy; currently the most commonly used method for wetland mapping) and a wetness index map derived from a digital elevation model. The potential of LiDAR intensity data is strong for addressing issues related to the regulatory status of wetlands and measuring the delivery of ecosystem services.

Tetramesa romana alone and T. romana plus R. donacis significantly damaged A. donax by suppressing leaf and stem lengths and stimulated production of side branches during a 12-week period. R. donacis plus T. romana only slightly more impacted the plant than did T. romana alone, most likely because of the longer life cycle of R. donacis that may require a longer period of time to cause measurable damage. No negative interactions were observed between the two candidate biological control agents. Therefore, based on their potential to significantly damage A. donax under greenhouse conditions and their narrow host ranges, T. romana and R. donacis are suitable candidates for biological control of this invasive reed grass in North America.

Our survey indicated the current range of the vole includes the area from Wahkeena Creek, 20 km east of Troutdale to Seneca Fouts State Park, 6 km west of Hood River. We also found a concentration of Red Tree Vole nests in the headwaters of the Lake Branch of Hood River, 27 km southwest of the town of Hood River. Of 70 vole nests located, 36 (52%) were old unoccupied nests with no evidence of recent use, 24 (34%) were unoccupied but had evidence of recent use as indicated by the presence of fresh green resin ducts or cuttings in the nest, and 10 (14%) were occupied by voles. Of the 70 vole nests, 74% were in forests dominated by mature or old-growth trees and 26% were in stands 25- to 60-y-old. This survey is the first to document the existence of Red Tree Voles in the upper Columbia River Gorge east of Cascade Locks. It also documents the occurrence of Red Tree Voles on the east slope of the Cascade Range in the headwaters of the Lake Branch of Hood River.

Nutt. (subalpine fir) in western North America. Little information is available on the life cycle and ecology of this insect in Colorado. In this study in north central Colorado, we examined its flight periodicity, attack patterns, and life cycle in downed trees. Flight season, as indicated by pheromone-trap catches, began in early June. Peak flight was observed during early to mid-July. A second peak in flight was observed in some years, but its occurrence was not consistent. Preferred attack sites on downed trees were the underside or side of the log and through branch stubs. The life cycle for this beetle was completed in 2 years, consistent with earlier observations from British Columbia. Sex ratio was 1:1, but a higher percentage of males fly earlier in the season.

Evidence of adventive populations of the arundo wasp in the Lower Rio Grande Basin was confirmed with a spatio-temporal survey spanning more than 350 river miles. A total of 2,414 adult females of T. romana was collected during a 14month period of study in 2008-2009. This study documents the initial locations and regional expansion of two adventive populations of T. romana, centered around the cities of Eagle Pass and Laredo, TX. Peaks in T. romana abundance in August 2008 and June 2009 indicate a region-wide positive association between abundance of T. romana and warm summer temperatures. Correlations between site-specific abundance data and weather suggest the presence of populationspecific associations with both temperature and rainfall.

The objective of this study was to determine the effects of dexamethasone (Dex) immunosuppressive treatment and transport stress on the isolation of L. monocytogenes in an E. coli-L. monocytogenes challenge model. Thirteen-week-old male turkeys housed in floor pens were either nonchallenged (NCH) or challenged (CH) by environmental exposure to E. coli and L. monocytogenes Scott A, using both a coarse spray and feed inclusion. One group of both NCH and CH birds was not stressed (NCH-Con and CH-Con, respectively), a second group was treated with Dex during challenge (NCH-Dex and CH-Dex, respectively), and a third group was subjected to a 12-hour transport (Trans) stress protocol at 15 wk of age (NCH-Trans and CH-Trans, respectively). All birds were bled and necropsied the morning after transport. Dexamethasone treatment increased mortality and disease incidence. The CH-Con, CH-Trans, and CH-Dex birds, as well as the NCH-Dex birds, had lowered body weights compared to the NCH-Con. The relative liver and heart weights were increased, and the relative bursal weights were decreased by both NCH-Dex and CH-Dex treatments. The heterophil:lymphocyte ratio, a measure of the stress response, was increased by CH-Trans, NCH-Dex, and CH-Dex. Total erythrocyte counts and hematocrit were decreased by NCH-Trans, CH-Trans, NCH-Dex and CH-Dex. The challenge strain of E. coli was isolated from the organs of a significant number of CH-Dex birds using direct plating and occasionally from CH-Trans birds. Listeria monocytogenes was not isolated from significant numbers of birds using direct plating, but was isolated from the knee or hip synovial tissues of a significant percentage of CH-Dex birds using pre-enrichment cultural methods, and from CH-Trans and CH-Dex birds using real-time PCR detection. These data suggest that L. monocytogenes colonization of processing-age turkeys can be increased by stress, and the organism may be harbored within inapparent infections of turkey synovial tissue.

As applied to watershed management, social infrastructure includes mechanisms to design, carry out, evaluate, and modify plans for resource protection or restoration. Efforts to apply the best science will not bring anticipated results without the appropriate social infrastructure. For the Long Tom Watershed Council, social infrastructure includes a management structure, membership, vision, priorities, partners, resources, and the acquisition of scientific knowledge, as well as the communication with and education of people associated with and affected by actions to protect and restore the watershed. Key to integrating science and practice is keeping science in the loop, using data collection as an outreach tool, and the Long Tom Watershed Council's subwatershed enhancement program approach. Resulting from these methods are ecological leadership, restoration projects, and partnerships that catalyze landscape-level change.

It is increasingly recognized that watersheds historically passed through different conditions over time. Habitat conditions varied in quantity and quality, primarily as a function of the time since the last major disturbance and the legacy of that disturbance. Thus, to match the effects of historical processes, we would expect a variety of conditions to exist across the watersheds in a region at any time. Additionally, watersheds have different potentials to provide habitat for given fish species because of variation in physical features. This developing ecological understanding is often preempted by social desires to bring all watersheds to a "healthy" condition, which in turn is reflected in a common regulatory approach mandating a single condition as the long-term goal for all watersheds. Matching perceptions and regulations to the way aquatic systems actually change and evolve through time will be a major challenge in the future.

AN - 754889561; 13463187 AB - Cold storage of insects is a common practice used when transporting insects or to assist with efforts to increase the size of a colony. However, cold storage affects egg, nymphal and adult survival, fecundity, and egg viability. We evaluated the influence of nutrient source on the response of eggs, nymphs and adults of Perillus bioculatus when exposed to two temperatures most likely to be used for short and extended storage by comparing natural prey-fed insects to artificial diet-fed insects. The results of our study showed that the survival of eggs from either prey-fed or diet-fed insects declined at both 4 and 10C as the length of storage exceeded one week. The survival of nymphs exposed to cold storage treatment was slightly higher than for eggs, with a similar response to time of storage. Unique to the nymphal stage was the superior performance of diet-fed insects over prey-fed insects. However, of the three developmental stages tested, the best survival was obtained with adults. Our results show that both prey-fed and diet-fed adults were able to withstand cold storage at 10C for three weeks with very little loss of survival, fecundity or viability of eggs oviposited by those adults. Longer periods of storage resulted in a decline in survival, fecundity and egg viability and that decline was greatest at 4C. Outcross mating of cold stored adults with adults held at 26C indicated that adult females were more detrimentally affected by cold storage than males. There were differences in the response of P. bioculatus to cold storage compared to previously reported responses of P. maculiventris. However, the most notable difference is that P. maculiventris did better at almost all parameters than P. bioculatus. Collectively, these results demonstrate a nutrient influence on the response to cold storage at different developmental stages.

We utilized polycarbonate filters to collect total airborne endotoxins, sonication as the extraction technique, and 0.05% Tween 20 in pyrogen-free water (PFW) as the extraction solution. Endotoxin concentrations were determined via the Limulus amebocyte lysate (LAL) assay. The endotoxin concentrations in extracts after 15 and 30 min of filter sonication were similar, while the concentration in 60 min extracts was about twofold lower. Rapidly vortexing samples for up to 15 min after sonication did not increase the endotoxin concentration. However, concentrations were 13 and 26% lower in extracts that were centrifuged at 1,000 and 10,000g for up to 15 min, respectively. Field samples and endotoxin standard were also sonicated in glass or polypropylene tubes for up to 120 min. Regardless of the extraction vessel, a decrease in endotoxin concentration occurred when sonicated for >30 min. Samples and endotoxin standard subjected to 12 freeze--thaw cycles at -20C only showed a slight but not significant decrease in endotoxin concentration. Our results also demonstrate the importance of simultaneously adding LAL reagent to 96-well plates before initiating the LAL assay.

Development of K C can assist in predicting crop irrigation needs using meteorological data from weather stations. The objective of the research was conducted to determine growth-stage-specific K C and crop water use for maize (Zea Mays) and sorghum (Sorghum bicolor) at Texas AgriLife Research field in Uvalde, TX, USA from 2002 to 2008. Seven lysimeters, weighing about 14Mg, consisted of undisturbed 1.5mA-2.0mA-2.2m deep soil monoliths. Six lysimeters were located in the center of a 1-ha field beneath a linear-move sprinkler system equipped with low energy precision application (LEPA). A seventh lysimeter was established to measure reference grass ETO. Crop water requirements, K C determination, and comparison to existing FAO K C values were determined over a 3-year period for both maize and sorghum. Accumulated seasonal crop water use ranged between 441 and 641mm for maize and between 491 and 533mm for sorghum. The K C values determined during the growing seasons varied from 0.2 to 1.2 for maize and 0.2 to 1.0 for sorghum. Some of the values corresponded and some did not correspond to those from FAO-56 and from the Texas High Plains and elsewhere in other states.

This research was conducted to determine growth-stage-specific Kc and crop water use for cotton (Gossypium hirsutum) and wheat (Triticum aestivum) at the Texas AgriLife Research field at Uvalde, TX, USA from 2005 to 2008. Weighing lysimeters were used to measure crop water use and local weather data were used to determine the reference evapotranspiration (ETo). Seven lysimeters, weighing about 14Mg, consisted of undisturbed 1.5mA-2.0mA-2.2m deep soil monoliths. Six lysimeters were located in the center of a 1-ha field beneath a linear-move sprinkler system equipped with low energy precision application (LEPA) and a seventh lysimeter was established to measure reference grass ETo. Crop water requirements, Kc determination, and comparison to existing FAO Kc values were determined over a 2-year period on cotton and a 3-year period on wheat. Seasonal total amounts of crop water use ranged from 689 to 830mm for cotton and from 483 to 505mm for wheat. The Kc values determined over the growing seasons varied from 0.2 to 1.5 for cotton and 0.1 to 1.7 for wheat. Some of the values corresponded and some did not correspond to those from FAO-56 and from the Texas High Plains and elsewhere in other states. We assume that the development of regionally based and growth-stage-specific Kc helps in irrigation management and provides precise water applications for this region.

We compared the chemical profiles obtained from cuticular extracts of diapausing and post-diapause winterform males and females to isolate and identify the pheromone. Post-diapause females produced significantly more of the cuticular hydrocarbon, 13-methylheptacosane, than post-diapause males and diapausing females. In olfactometer assays, conspecific males were attracted to synthetic racemic 13-methylheptacosane, whereas females were not, indicating that the behavioral response to this chemical is sex-specific. Furthermore, 13-methylheptacosane was as attractive to males as a cuticular extract of females, suggesting that this chemical was largely responsible for the female attractiveness. A field study showed that males but not females were attracted to 13-methylheptacosane, confirming the olfactometer results. This study provides evidence that 13-methylheptacosane is a sex attractant pheromone for C. pyricola winterform males. This is the first identification of a sex pheromone in the Psylloidea. Our results open the path to developing monitoring tools and possibly new strategies for integrated pest management of this insect.

Two diets differing significantly in energy content were employed in choice tests so that incentive to consume repellent-treated diets varied according to which diet was treated. When the high-energy diet was treated with repellents, only blood (flavor modification) and capsaicin (irritation) proved highly effective. Rapid habituation to the odor of meat and bone meal (neophobia) presented in a sachet limited its effectiveness as a repellent under conditions with a high feeding motivation. Thiram, a stimulus used to condition aversions, was not strongly avoided in these trials, that included only limited exposures to the repellent. These data support previous studies indicating that habituation to odor limits the effectiveness of repellents that are not applied directly to food, while topically-applied irritants and animal-based products produce significant avoidance.

We contend that both approaches have value and need not be mutually exclusive. Anthropogenic influences have pushed many ecosystems across ecological thresholds, to less desirable states, so that actively managing for "domesticated nature" - nature as modified, either intentionally or inadvertently, by humans - is more realistic and more likely to succeed than recreating the original ecosystem. Furthermore, when domesticated nature is the most reasonable objective, empirical performance, together with geographical origin, are plausible criteria for choosing restoration plant material. For altered ecosystems, we suggest that evolution should be assisted by the inclusion of plants that (1) reflect general historical evolutionary patterns, (2) are particularly suited to the modified environment, (3) are able to adapt to contemporary selection pressures, and (4) contribute to the restoration of ecosystem structure and function.

Ten indicators of vegetation and soil status are rated on a 1 to 5 scale and are summed to give an aggregate score, which is interpreted for management recommendations. Information is lacking, however, on how PCS results vary within and among environments and farms. We applied the PCS on two farms in Pennsylvania (one dairy, one beef), two dairy farms in New York, and an organic dairy in Maryland. All pastures (25 to 63 per farm) on each farm were evaluated according to PCS methodology in spring, summer, and autumn of 2004, 2005, and 2006. Aggregate PCS scores ranged from 30 to 40 (indicating some improvements were needed to pasture management) and were relatively stable within management recommendation categories across seasons in 2004 and 2006. The PCS scores in 2005, however, plummeted (below 25 to 30--indicating major management changes to prevent degradation) on the Pennsylvania and Maryland farms because of drought. Pastures used for heifers and dry cows or as wintering areas often had lower scores than other pastures. Typically, these pastures were on less productive soils, steep slopes, and were stocked intensively. There was much overlap among individual score categories for some indicators, which suggests that fewer but broader score categories (e.g., low, medium, high) would simplify the system for farmers. The monitoring workload could be reduced by assessing representative subsets of pastures managed similarly or in similar landscape positions instead of all pastures on a farm.

We examined aerenchyma formation in roots and its effect on the suitability of 26 native warm-season grass cultivars from six species for use in riparian areas. In a greenhouse study, all cultivars exhibited extensive aerenchyma formation in well-drained soil, and percent aerenchyma was greater in the well-drained control than in the saturated treatment (89% versus 71%, respectively). However, the presence of extensive aerenchyma development did not guarantee good root growth under anaerobic conditions. Suitable plant materials for inclusion in riparian areas were found among four of the six warm-season species examined, although a wide range in suitability was observed within species where multiple cultivars were tested. Nine cultivars representing a range of responses were further evaluated at four field locations subjected to flooding and soil saturation. Red River prairie cordgrass (Spartina pectinata L.) provided superior performance at all locations. The worst performing cultivars in the greenhouse study also performed poorly in the field. However, not all cultivars that performed well in the greenhouse also performed well in the field. Osage Indiangrass (Sorghastrum nutans L.) was the third ranked cultivar for flooding tolerance in the greenhouse but had acceptable performance at only one of the four field sites. Conversely, Meadowcrest eastern gamagrass (Tripsacum dactyloides L.) exhibited only moderate flooding tolerance in the pot study but had among the lowest mortality, highest vigor, and highest biomass at three of the four locations. Controlled environment studies were useful for eliminating unacceptable cultivars, but field studies were necessary to identify suitable material for riparian areas.

Thus, the objective of this study was to determine the water quality effects of repeated annual poultry litter application as a cropland and pasture fertilizer. Eight years of data collected on ten field-scale watersheds indicated several significant water quality differences based on litter rate (0.0 to 13.4 Mg ha super(-1) [0 to 6 ton ac super(-1)]) and land use (cropland and pasture). On cropland fields, increasing litter rates (with corresponding decreases in supplemental inorganic nitrogen [N]) increased runoff orthophosphate phosphorus (PO sub(4)-P) concentrations but reduced extreme high nitrate nitrogen (NO sub(3)-N) concentrations. Whereas runoff PO sub(4)-P concentrations were somewhat similar between land uses, NO sub(3)-N concentrations were much lower in pasture runoff because of supplemental inorganic N application, reduced nutrient uptake potential, and faster litter mineralization on cropland. Although considerable variability was observed, intra-annual runoff NO sub(3)-N and PO sub(4)-P concentrations generally exhibited curvilinear decay based on time since fertilizer application. In spite of repeated annual litter application and buildup of soil phosphorus (P) at high litter rates, few long-term trends in N and P runoff were evident due to the dynamic interaction between transport and source factors. These results support several practical implications, specifically: (1) combining organic and inorganic nutrient sources can be environmentally friendly and economically sound if application rates are carefully managed; (2) high runoff N and P concentrations can occur from well-managed fields, which presents difficulty in regulating edge-of-field water quality; and (3) change in the animal industry mindset to view by-products as marketable resources could mitigate environmental problems, provide alternative fertilizer sources, and enhance animal industry revenue opportunities.

We examined the effects of light exposure and girdling on green ash (Fraxinus pennsylvanica Marsh) volatile production, and effects of light exposure, girdling, and leaf age on emerald ash borer adult feeding preferences and phototaxis. Green ash seedlings grown under higher light exposure had lower amounts of three individual volatile compounds, (Z)-3-hexenol, (E)-b-ocimene, and (Z,E)-a-farnesene, as well as the total amount of six detected volatile compounds. Girdling did not affect the levels of these volatiles. Emerald ash borer females preferred mature leaves, leaves from girdled trees, and leaves grown in the sun over young leaves, leaves from nongirdled trees, and leaves grown in the shade, respectively. These emerald ash borer preferences were most likely because of physical, nutritional, or biochemical changes in leaves in response to the different treatments. Emerald ash borer females and males showed positive phototaxis in laboratory arenas, a response consistent with emerald ash borer preference for host trees growing in sunlight.

We report on use of automated pheromone-baited traps that use a recording sensor and data logger to record the unique date-time stamp of males as they enter the trap. We deployed a total of 352 automated traps under field conditions across several U.S. states over a 5-yr period. In many cases, there was general congruence between male moth capture and the number of recorded events. Although it was difficult to decipher an individual recording event because of the tendency for over-recording, the overall distribution of recorded events was useful in assessing male gypsy moth flight behavior and phenology. The time stamp for recorded events corroborated a previous report of crepuscular gypsy moth male flight behavior, because, although most moths were trapped between 12 and 16 h, there was a consistent period of flight activity between 20 and 22 h. The median male flight duration was 24 d (228 DD, base threshold = 10C), but there were several traps that recorded flight periods >42 d that could not be explained by overcounting given the congruence between moth capture and the number of recorded events. Unusually long flight periods could indicate the introduction of male moths or other life stages that developed under different climatic conditions.

E. Smith) (Lepidoptera: Noctuidae), infestations in most of North America arise from annual migrations of populations that overwinter in southern Texas and Florida. Cytochrome oxidase I haplotype profiles within the fall armyworm corn strain, the subgroup that preferentially infests corn (Zea mays L.), can differentiate the Texas and Florida populations. We use this molecular metric to show that fall armyworms in central Pennsylvania originate from Texas, indicating the existence of a migratory pathway from Texas to the northeastern United States. These results were compared with historical trapping data for fall armyworm and another migratory noctuid, corn earworm Helicoverpa zea (Boddie) (Lepidoptera: Noctuidae), in the Pennsylvania and Maryland corn-producing areas to better define lepidopteran migratory pathways.

As summarized by Helms (2009), the concerns of Bennett and others eventually led to the formation of the Soil Erosion Service, which was the precursor to the Soil Conservation Service and was created within the USDA in 1935 (Bennett 1933). Here I provide a historic perspective of the use of US agricultural lands and soil carbon (C), compare amounts of soil organic carbon (SOC) in cropland versus land that has never been cultivated (native), and consider the future role of SOC in US agricultural lands. Within this context, the protection of SOC has been and will continue to be a necessary component to the economic and environmental health of US agriculture.

AN - 734143298; 19783636 AB - Fumonisins are mycotoxins produced by Fusarium verticillioides. They are toxic to animals and exert their effects through mechanisms involving disruption of sphingolipid metabolism. Fumonisins are converted to their hydrolyzed analogs by alkaline cooking (nixtamalization). Both fumonisins and hydrolyzed fumonisins are found in nixtamalized foods such as tortillas, and consumption of tortillas has been implicated as a risk factor for neural tube defects (NTD). Fumonisin B(1) (FB(1)) induced NTD when given (ip) to pregnant LM/Bc mice; however, neither the NTD induction potential of hydrolyzed fumonisin B(1) (HFB(1)) nor its affect on sphingolipid metabolism in pregnant mice have been reported. The teratogenic potential of FB(1) and HFB(1) was therefore compared using the LM/Bc mouse model. Dams were dosed (ip) with 2.5, 5.0, 10, or 20 mg/kg (< or = 49 micromol/kg) body weight (bw) HFB(1) on embryonic day (E)7-E8. Negative and positive control groups were given vehicle or 10 mg/kg (14 micromol/kg) bw FB(1), respectively. The high dose of HFB(1) disrupted sphingolipid metabolism, albeit slightly, but did not cause maternal liver lesions or NTD (n = 8-10 litters per group). In contrast, 10 mg/kg bw FB(1) markedly disrupted maternal sphingolipid metabolism, caused hepatic apoptosis in the dams, increased fetal death rates, and decreased fetal weights. Furthermore, NTD were found in all FB(1)-exposed litters (n = 10), and 66 +/- 24% of the fetuses were affected. The findings indicate that HFB(1) does not cause NTD in the sensitive LM/Bc mouse model and only weakly disrupts sphingolipid metabolism at doses up to sevenfold higher (micromole per kilogram body weight basis) than the previously reported lowest observed adverse effect level for FB(1).

AN - 734142029; 19733471 AB - Experimental studies demonstrated that maternal exposure to certain environmental and dietary factors during early embryonic development can influence the phenotype of offspring as well as the risk of disease development at the later life. DNA methylation, an epigenetic phenomenon, has been suggested as a mechanism by which maternal nutrients affect the phenotype of their offspring in both honeybee and agouti mouse models. Phenotypic changes through DNA methylation can be linked to folate metabolism by the knowledge that folate, a coenzyme of one-carbon metabolism, is directly involved in methyl group transfer for DNA methylation. During the fetal period, organ-specific DNA methylation patterns are established through epigenetic reprogramming. However, established DNA methylation patterns are not immutable and can be modified during our lifetime by the environment. Aberrant changes in DNA methylation with diet may lead to the development of age-associated diseases including cancer. It is also known that the aging process by itself is accompanied by alterations in DNA methylation. Diminished activity of DNA methyltransferases (Dnmts) can be a potential mechanism for the decreased genomic DNA methylation during aging, along with reduced folate intake and altered folate metabolism. Progressive hypermethylation in promoter regions of certain genes is observed throughout aging, and repression of tumor suppressors induced by this epigenetic mechanism appears to be associated with cancer development. In this review, we address the effect of folate on early development and aging through an epigenetic mechanism, DNA methylation.

AN - 733942753; 19592239 AB - Used cooking or frying oils are of increasing interest as inexpensive feedstock for biodiesel production. In this work, used frying oils obtained from 16 local restaurants were investigated regarding their fatty acid profile vs. the fatty acid profile of the oil or fat prior to use. The fatty acid profiles were analyzed by gas chromatography and proton nuclear magnetic resonance spectroscopy. Besides the fatty acid profile, the acid value and dynamic viscosity of the samples were determined. Dynamic viscosity was determined because of non-Newtonian behavior of some samples. The results indicate that oils and fats experience various degrees of increase in saturation during cooking/frying use, with the magnitude of these changes varying from sample to sample, i.e., a high degree of randomness of composition is found in used frying oil samples. Properties of the samples that were investigated were acid value and viscosity which consistently increased with use, also in a random fashion. Multiple independent samples obtained from the same restaurants indicate that there is little consistency of used cooking oil obtained from the same source. These results are discussed with regards to the potential fuel properties of biodiesel derived from these used frying oils.

AN - 733856752; 19843228 AB - Trichothecenes are terpene-derived secondary metabolites produced by multiple genera of filamentous fungi, including many plant pathogenic species of Fusarium. These metabolites are of interest because they are toxic to animals and plants and can contribute to pathogenesis of Fusarium on some crop species. Fusarium graminearum and F. sporotrichioides have trichothecene biosynthetic genes (TRI) at three loci: a 12-gene TRI cluster and two smaller TRI loci that consist of one or two genes. Here, comparisons of additional Fusarium species have provided evidence that TRI loci have a complex evolutionary history that has included loss, non-functionalization and rearrangement of genes as well as trans-species polymorphism. The results also indicate that the TRI cluster has expanded in some species by relocation of two genes into it from the smaller loci. Thus, evolutionary forces have driven consolidation of TRI genes into fewer loci in some fusaria but have maintained three distinct TRI loci in others.

The number of food-insecure people in the 70 developing countries studied by ERS is estimated to increase 2% in 2009, after growing 11% in 2008.

Although market forces and biological factors both influence corn yields, research investments have been a major factor behind continued increases in corn yields. Continued scientific advances could accelerate the rate of growth in corn yields, but achieving a nationwide yield of 300 bushels per acre by 2030 would require a tripling of the projected growth rate, and would be historically unprecedented.

Methods Forty-two Boy Scout troops (n = 473, 10- to 14-year-old Scouts) in Houston, TX, were randomly assigned to condition. The 9-week program included approximately 30 min of weekly troop time, plus 25 min of weekly Internet programming. The intervention was delivered in two waves (Spring and Fall). Data were collected in 2003-2004, and analyses were completed in 2008. Main outcomes were FJ and LV consumption (validated food frequency questionnaire). FV self-efficacy, preferences, and home availability were also measured. Results Significant increases in FJ consumption (p = .003), FJ home availability (p = .009), and LV self-efficacy (p = .004) were observed among the intervention group immediately following the intervention but were not maintained 6 months later. Conclusion A Boy Scout troop-plus-Internet intervention promoting FJ and LV consumption resulted in short-term changes in FJ consumption among U.S. Boy Scouts. Future research should investigate ways to extend these results to LV and maintain the increases over time.

Availability of information, vulnerability of ecological and socio-economic systems, and uncertainties associated with climate change, as well as the interacting non-climatic changes, influence selection of the adaptation approach. Resource assessments are opportunities to develop strategic information that could be used to identify and link adaptation strategies across planning levels. Within a National Forest, planning must incorporate the opportunity to identify vulnerabilities to climate change as well as incorporate approaches that allow management adjustments as the effects of climate change become apparent. The nature of environmental variability, the inevitability of novelty and surprise, and the range of management objectives and situations across the National Forest System implies that no single approach will fit all situations. A toolbox of management options would include practices focused on forestalling climate change effects by building resistance and resilience into current ecosystems, and on managing for change by enabling plants, animals, and ecosystems to adapt to climate change. Better and more widespread implementation of already known practices that reduce the impact of existing stressors represents an important 'no regrets' strategy. These management opportunities will require agency consideration of its adaptive capacity, and ways to overcome potential barriers to these adaptation options.

The objectives of this study were: (1) to determine theyields and properties of antioxidants (henceforth referring to total phenolics in terms of tannic acid equivalent) and oil extracted from various dry and wet constituents of PM, including peel, seeds, and mixture; and (2) to evaluate the anaerobic digestibility and biogas production potential of PM before and after antioxidant extraction (AE) and oil extraction (OE). Water and petroleum ether were used as solvents in the extraction of antioxidants and oil, respectively. The anaerobic digestion tests were conducted at 35 C 2 cC with a feedstock to microorganism ratio of 0.5 on volatile solid (VS) basis under two initial organic loadings of 3.0 and 5.0 g VS L(-1). According to the results, both dry and wet PM extracts had similar extraction efficiency and functionality. The wet PM extract had an antioxidant content of 23.0%, which corresponded to an antioxidant yield of 106 kg per ton of PM peel on dry basis (d.b.). The DPPH scavenging activities of antioxidants were 6.5 to 6.6 g g(-1) (d.b.). The oil yield from the dry PM seeds was 138 kg ton(-1) (d.b.). Compared to the low initial organic loading, the high initial organic loading improved methane content (55.1% to 67.5%) but not biogas yield. The extracted residuals of peel, seeds, and mixture had methane yields of 148, 183, and 161 mL g(-1) VS, respectively, which were lower than that from raw PM. Because the integrated process of extraction followed by anaerobic digestion can produce high functional antioxidants and high-quality biogas and oil from the PM, it is recommended as a value-added utilization method for the by-product.

The Centers for Disease Control and Prevention is working to identify and promote evidence-based physical activity programs to improve physical function among adults with arthritis. The authors conducted a multisite, pilot randomized controlled trial to examine the effects of community-based strength training versus usual activity in women (n = 33) 55 years of age and older with arthritis. The moderate-intensity, progressive strength training intervention included balance and flexibility exercises. Classes met 2 times per week for 12 weeks. Outcome measures included muscle strength, performance-based physical function (mobility, flexibility, and balance), and arthritis symptoms. Lower body strength improved from baseline to 12 weeks in the strength training versus control group (32.2%-7.3%, respectively; P = .004). Physical function improved in the strength training group over 12 weeks (range, 7%-50%; P < .05), with no change in control group. Adherence to the intervention was 82% c 16%. There were no adverse effects on arthritis symptoms. These results demonstrate the efficacy of this program and its potential to be disseminated as an evidence-based strength training intervention to improve physical function and strength among older women with arthritis and other major comorbidities.

However, the water quality effects of pond ash amended surfaces are not well understood. The objectives of this field investigation were to: (1) compare feedlot soil properties, and nutrient and bacterial transport in runoff, from pond ash amended surfaces and soil surfaces; (2) compare the effects of unconsolidated surface materials (USM) (loose manure pack) and consolidated subsurface materials (CSM) (compacted manure and underlying layers) on nutrient and bacterial transport in runoff; and (3) determine if the measured water quality parameters are correlated to soil properties. Simulated rainfall events were applied to 0.75 m wide X 2m long plots with different surface materials and surface conditions. Measurements of calcium, magnesium, sulfur, and pH were found to be significantly greater on the pond ash amended surfaces. In comparison, the soil surfaces contained significantly greater amounts of Bray 1-P. The runoff load of NH(4)-N was significantly greater on the pond ash amended surfaces, while the total phosphorus (TP) load was significantly greater on the soil surfaces. The NO(3)-N and total nitrogen (TN) loads in runoff were significantly greater on the feedlot surfaces containing CSM. Concentrations of E. coli in runoff were similar on the pond ash amended surfaces and soil surfaces. The dissolved phosphorus (DP), particulate phosphorus (PP), and TP load of runoff were all significantly correlated to Bray 1-P measurements.

Production of these virulence factors is under the control of a complex network of global regulatory elements, one of which is sarA. sarA encodes a DNA binding protein that is considered to function as a transcription factor capable of acting as either a repressor or an activator. Using competitive ELISA assays, we demonstrate that SarA is present at approximately 50 000 copies per cell, which is not characteristic of classical transcription factors. We also demonstrate that SarA is present at all stages of growth in vitro and is capable of binding DNA with high affinity but that its binding affinity and pattern of shifted complexes in electrophoretic mobility shift assays is responsive to the redox state. We also show that SarA binds to the bacteriophage lambda (l) attachment site, attL, producing SarA-DNA complexes similar to intasomes, which consist of bacteriophage lambda integrase, Escherichia coli integration host factor and attL DNA. In addition, SarA stimulates intramolecular excision recombination in the absence of l excisionase, a DNA binding accessory protein. Taken together, these data suggest that SarA may function as an architectural accessory protein.

Of particular importance are day-use sites, which receive a large amount of use but little research emphasis. Managers of urban-proximate day-use sites can better manage with detailed specific information about participation patterns, site preferences, and visitor perceptions. Results are offered from visitor contact surveys conducted at day-use sites on four urban national forests in Southern California between 2001 and 2004, with a focus on areas where Latinos recreate. These data indicate many similarities among the Latino visitors to specific sites in four Southern California forests. There were commonalities in participation in outdoor recreation activities, the relative importance of site attributes, and perceptions reported about their recreation experiences. The results suggest that management decisions about serving these groups consider the range of activity options identified, that there is a consistent desire for facilities and amenities, and that the Latino visitors are likely to continue to recreate in these places and will tell others about it, probably leading to increased use by these respondent groups in the future.

We surveyed down wood and vegetation cover along transects from stream center, through buffers ranging from <5 to 150 m width into thinned stands, patch openings, or unthinned stands of 40- to 65-year-old Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco) forests in western Oregon, USA. Small-wood cover became more homogeneous among stream reaches within 5 years following thinning, primarily due to decreases for reaches having the greatest pretreatment abundance. Mean shrub cover converged, predominantly because of decreases in patch openings. Herbaceous cover increased, particularly in patch openings. Relative to unthinned stands, herbaceous cover was similar in wide buffers and increased in the narrowest buffers and in narrow buffers adjacent to patch openings. Moss cover tended to increase in thinned areas and decrease in patch openings. Both conventional point-null hypothesis tests and inequivalence tests suggested that wood and vegetation responses within buffers of .15 m width were insensitive to the treatments. However, inherently conservative equivalence tests infrequently inferred similarity between thinned stands or buffers and untreated stands. Difficulties defining ecologically important effect size can limit the inferential utility of equivalence-inequivalance testing.Original Abstract: L'efficacite combinee de l'eclaircie et de lisieres boisees riveraines en vue d'augmenter la complexite structurelle dans des forets de seconde venue tout en maintenant leurs fonctions riveraines n'est pas bien documentee. Nous avons echantillonne le bois mort au sol et le couvert vegetal le long de transects etablis a partir du milieu de ruisseaux vers des lisieres boisees riveraines dont la largeur variait de <5 a 150 m et jusque dans des peuplements eclaircis, des trouees ou des peuplements non eclaircis de Douglas de Menzies (Pseudotsuga menziesii (Mirb.) Franco) de 40-65 ans dans l'ouest de l'Oregon, aux Etats-Unis. Le couvert de jeunes arbres est devenu plus homogene entre les biefs durant les cinq annees suivant l'eclaircie, essentiellement a la suite de la diminution du nombre de tiges dans les biefs qui etaient denses avant d'etre traites. Le couvert moyen d'arbustes est devenu plus uniforme, principalement a cause de la diminution du nombre de trouees. Le couvert herbace a augmente, en particulier dans les trouees. Le couvert herbace des lisieres boisees les plus larges etait semblable a celui des peuplements non eclaircis, mais il devenait plus important dans les lisieres boisees les plus etroites et dans les lisieres boisees etroites adjacentes a des trouees. Le couvert muscinal tendait a augmenter dans les sites eclaircis et a decroitre dans les trouees. Des tests classiques d'hypotheses nulles realisees selon les methodes statistiques frequentistes et des tests de non-equivalence selon l'approche bayesienne ont tous suggere que les reponses du bois mort et du couvert vegetal dans les lisieres boisees de 15 m de largeur et plus n'etaient pas influencees par les traitements. En revanche, des tests d'equivalence plutot conservateurs ont suggere a quelques reprises qu'il y avait des similarites entre les peuplements eclaircis ou les lisieres boisees et les peuplements non traites. Des difficultes liees a la definition de l'ampleur que devrait avoir un effet pour etre ecologiquement important peuvent limiter l'utilite des tests d'equivalence ou de non-equivalence pour tirer des conclusions.

This symbiotum is implicated in the reduction of stresses, including plant-parasitic nematodes. To substantiate this implication, toxicological effects of root extracts, polyphenolic fraction, ergot, and loline alkaloids from endophyte-infected tall fescue were investigated using Pratylenchus scribneri, a nematode pest of tall fescue. In vitro bioassays and greenhouse studies were used as tests for effects of root fractions and compounds on motility and mortality of this lesion nematode. Greenhouse studies revealed that endophyte-infected tall fescue grasses are essentially nonhosts to P. scribneri, with root populations averaging 3 to 17 nema-todes/pot, compared with 4,866 and 8,450 nematodes/pot for noninfected grasses. The in vitro assay indicated that root extracts from infected tall fescues were nematistatic. Polyphenols identified in extracts included chlorogenic acid, 3,5-dicaffeoylquinic acids, caffeic acid, and two unidentified compounds, but these were not correlated with endophyte status, qualitatively or quantitatively. Tests of several ergot alkaloids revealed that ergovaline and a-ergocryptine were nematicidal at 5 and 50 kg/ml, respectively, while ergocornine and ergonovine were nematistatic at most concentrations. Loline (N-formylloline), the pyrrolizidine alkaloid tested, was nematicidal (50 to 200 kg/ml). The ecological benefits of the metabolites tested here should assist in defining their role in deterring this nematode species while offering some probable mechanisms of action against plant-parasitic nematodes in general.

These utilities are two of eleven in the state with a waiver from Filtration. In 2004, the source water monitoring program for the Auburn Water District and City of Lewiston Water Division detected a significant increase in bacteria levels in Lake Auburn. With assistance from environmental consulting engineers, the source of the contaminant was linked to the presence of large flocks of gulls on the lake. The presentation will report on the integrated wildlife damage management approach for gull management on Lake Auburn conducted by the U.S. Department of Agriculture. Animal and Plant Health Inspection Service, Wildlife Services from 2005 through 2008. Results of a population survey and bird activity of the gull population in the areas surrounding the lake will be included. Data collected will be presented showing the successful efforts at gull management and the dramatic reduction in bacteria levels in Lake Auburn.

This study examines the profitability of commercial soybean production using a nationwide survey of soybean producers for 2006 that includes a targeted sample of organic growers. Treatment-effect models are specified to characterize adopters of the organic approach and to isolate the impact of organic choice on operating, operating and capital, and total economic costs of soybean production. Organic soybean producers tend to be younger, have less crop acreage, and are less likely to work off-farm than conventional producers. Organic soybean production costs range from about $1 to $6 per bushel higher than those for conventional soybeans due to both lower yields and higher per-acre costs, while the average organic price premium in 2006 was more than $9 per bushel. Long-term cropping systems data suggest significant returns to organic systems result from similar yields and lower costs than conventional systems, but the high returns to commercial organic production found in this study can only be attributed to the significant price premiums paid for organic soybeans. Average organic soybean price premiums have remained high since 2006 despite much higher conventional soybean prices as users of organic soybeans attempt to retain and attract more acreage. However, increases in conventional soybean prices and fuel prices reduce the incentive for planting organic soybeans by improving returns to conventional production and increasing the relative costs of organic production.

Swallows often nest in large colonies in habitats and months associated with high mosquito abundance and early WNV transmission in North America. Additionally, cliff swallow diet consists of insects, including mosquitoes, leading to an additional potential route of WNV infection. The average peak viremia titer among infected cliff swallows was 10 super(6.3) plaque-forming units (PFU)/mL serum and the reservoir competence index was 0.34. There was no correlation between dose and probability of becoming infected or viremia peak and duration. Oral shedding was detected from 2 to 14 days post-inoculation with an average peak titer of 10 super(4.4) PFU/swab. These results suggest that cliff swallows are competent reservoir hosts of WNV and therefore, they may play a role in early seasonal amplification and maintenance of WNV.

However, red alder generally is a short-lived pioneer species, and small logs can result in proportionally large volumes of lower grade lumber containing numerous visual defects, such as knots, often referred to as character marks. Given that markets for character-marked wood could provide an income stream for management of red alder, it becomes important to understand consumer and retailer response to character-marked red alder products. In the current study, we used a policy capturing approach (the lens model) to assess the cues used by furniture consumers and retailers to evaluate several furniture pieces constructed from character-marked red alder lumber. The cues used by consumers and retailers to form willingness-to-pay judgments were found to be different. Character marks, design, and naturalness were important to consumers. None of the investigated cues were significant to retailers, suggesting they were using an entirely different model. Such divergence creates challenges in the forestry supply chain for development of new forest products.Original Abstract: Au cours des recentes decennies, l'aulne rouge (Alnus rubra Bong.) est devenu une importante essence feuillue du la region nord-ouest du Pacifique dans les marches de bois d'[oeliguvre de categorie finition tels que les exportations, les meubles et les armoires. Cependant, l'aulne rouge est generalement une espece pionniere qui a une courte duree de vie, ce qui peut entrainer la production de petites billes avec un volume proportionnellement eleve de bois d'[oeliguvre de qualite inferieure qui contient de nombreux defauts apparents, tels que des n[oeliguds, souvent appeles marques de caractere. Etant donne que les marches pour le bois avec des marques de caractere pourraient fournir un flux de rentrees pour l'amenagement de l'aulne rouge, il devient important de comprendre la reaction des clients et des detaillants face aux produits fabriques avec de l'aulne rouge qui porte des marques de caractere. Dans cette etude, nous avons utilise une approche de capture politique (le modele lentille) dans le but de determiner les indicateurs utilises par les consommateurs et les detaillants de meubles pour evaluer plusieurs pieces de mobilier faites de bois d'aulne rouge avec des marques de caractere. Les indicateurs utilises par les consommateurs et les detaillants pour arriver a un jugement qui se traduit par la volonte de payer etaient differents. Les marques de caractere, le style et l'aspect naturel etaient importants pour les consommateurs. Aucun des indicateurs etudies n'etait important pour les detaillants, ce qui indique qu'ils utilisent un modele completement different. Une telle divergence cree des defis dans la chaine d'approvisionnement du secteur forestier pour le developpement de nouveaux produits.

We examined the interaction between two independent QTL (quantitative trait loci), SAP6 and SU91, on the expression of resistance to CBB in a pinto bean F sub(2) population and dark red kidney bean F sub(2) population. The disease reaction for each F sub(2) population was scored at several time points after inoculation. The dominant SCAR markers SAP6 and SU91 were simultaneously genotyped as codominant markers using a multiplex real-time PCR assay. For both populations, at each time point plants having genotypes of (su91 su91//SAP6 SAP6); (su91 su91//SAP6 sap6), and (su91 su91//sap6 sap6) were significantly more susceptible to CBB than plants with any of the six other possible genotypes (SU91 _//_ _). Only two examples were observed across both populations and all time points in which mean disease reactions were significantly different between any of the six (SU91 _//_ _) genotypes. No significant differences were observed between SU91 SU91 and SU91 su91 genotypes at any time point for either F sub(2) population. Similarly, no significant differences in CBB reaction were observed among the three SAP6 genotypes for plants that had the su 91/su91 genotype. The results indicate CBB resistance in these two populations is primarily conditioned by the presence of at least a single copy of the SU91 QTL. The effects of pathogen isolate and population on discerning the influence of QTL on CBB resistance are discussed.

These tools need to be flexible in terms of selection of soil functions to be assessed and indicators to be measured to ensure that assessments are appropriate for the management goals. The soil management assessment framework (SMAF) is being developed to meet this need. The SMAF uses soil physical, chemical and biological indicator data to assess management effects on soil function using a three-step process for (1) indicator selection, (2) indicator interpretation and (3) integration into an index. While SMAF is functional in its present format, it is intended to be malleable so that user needs can be met. Development of additional indicator interpretation scoring curves is one way that this framework can be expanded. Scoring curve development is a multi-step process of identifying an indicator, determining the nature of the relationship of the indicator to a soil function, programming an algorithm and/or logic statements describing that relationship and validating the resulting scoring curve. This paper describes the steps involved in developing an SMAF scoring curve. Scoring curves for interpreting water-filled pore space (WFPS) and Mehlich extractable potassium (K) were developed using the described protocol. This protocol will assist users of the SMAF in understanding how the existing scoring curves were developed and others interested in developing scoring curves for indicators that are not in the current version.

The two receptors were characterized by determining tissue distribution, ontogeny of receptor mRNA expression, and effects of exogenous homologous ghrelin administration on target tissue mRNA expression. Analysis of sequence similarities indicated two genes putatively encoding GHS-R1 and GHS-R2, respectively, which have been known to be present in zebrafish. Organization and tissue expression of the GHS-R1 gene was similar to that reported for other species, and likewise yielded two detectable mRNA products as a result of alternative splicing. Expression of both full-length, GHS-R1a, and splice variant, GHS-R1b, mRNA was highest in the pituitary. Gene organization of GHS-R2 was similar to GHS-R1, but no splice variant was identified. Expression of GHS-R2a mRNA was highest in the Brockmann bodies. GHS-R1a mRNA was detected in unfertilized eggs and throughout embryogenesis, whereas GHR-R2a mRNA was not expressed in unfertilized eggs or early developing embryos and was the highest at the time of hatching. Catfish intraperitoneally injected with catfish ghrelin-Gly had greater mRNA expression of GHS-R1a in pituitaries at 2 h and Brockmann bodies at 4 h, and of GHS-R2a in Brockmann bodies at 6 h post injection. Amidated catfish ghrelin (ghrelin-amide) had no observable effect on expression of either pituitary receptor; however, GHS-R1a and GHS-R2a mRNA expression levels were increased 4 h post injection of ghrelin-amide in Brockmann bodies. This is the first characterization of GHS-R2a and suggests regulatory and functional differences between the two catfish receptors.

To determine the compatibility of biological control and insect-resistant and herbicide-tolerant GM crop traits within integrated pest-management programs, this synthesis prioritizes understanding the bi-trophic and prey/host-mediated ecological pathways through which natural enemies interact within cropland communities, and how GM crops alter the agroecosystems in which natural enemies live. Insect-resistant crops can affect the quantity and quality of non-prey foods for natural enemies, as well as the availability and quality of both target and non-target pests that serve as prey/hosts. When they are used to locally eradicate weeds, herbicide-tolerant crops alter the agricultural landscape by reducing or changing the remaining vegetational diversity. This vegetational diversity is fundamental to biological control when it serves as a source of habitat and nutritional resources. Some inherent qualities of both biological control and GM crops provide opportunities to improve upon sustainable IPM systems. For example, biological control agents may delay the evolution of pest resistance to GM crops, and suppress outbreaks of secondary pests not targeted by GM plants, while herbicide-tolerant crops facilitate within-field management of vegetational diversity that can enhance the efficacy of biological control agents. By examining the ecological compatibility of biological control and GM crops, and employing them within an IPM framework, the sustainability and profitability of farming may be improved.

Of the 850 isolates typed, 101 EF-1a, 203 IGS rDNA, and 256 two-locus sequence types (STs) were differentiated. Analysis of the combined dataset suggests that two-thirds of the STs might be associated with a single host plant. This analysis also revealed that the 26 STs associated with human mycoses were genetically diverse, including several which appear to be nosocomial in origin. A congruence analysis, comparing partial EF-1a and IGS rDNA bootstrap consensus, identified a significant number of conflicting relationships dispersed throughout the bipartitions, suggesting that some of the IGS rDNA sequences may be non-orthologous. We also evaluated enniatin, fumonisin and moniliformin mycotoxin production in vitro within a phylogenetic framework.

In the course of an effort to explore the potential presence and roles of C. graminicola metabolites in maize, ethyl acetate extracts of solid substrate fermentations of several C. graminicola isolates from Michigan and Illinois were found to be active against Aspergillus flavus and Fusarium verticillioides, both mycotoxin-producing seed-infecting fungal pathogens. Chemical investigations of the extract of one such isolate (NRRL 47511) led to the isolation of known metabolites monorden (also known as radicicol) and monocillins I-III as major components. Monorden and monocillin I displayed in vitro activity against the stalk- and ear-rot pathogen Stenocarpella maydis while only the most abundant metabolite (monorden) showed activity against foliar pathogens Alternaria alternata, Bipolaris zeicola, and Curvularia lunata. Using LC-HRESITOFMS, monorden was detected in steam-sterilized maize stalks and stalk residues inoculated with C. graminicola but not in the necrotic stalk tissues of wound-inoculated plants grown in an environmental chamber. Monorden and monocillin I can bind and inhibit plant Hsp90, a chaperone of R-proteins. It is hypothesized that monorden and monocillins could support the C. graminicola disease cycle by disrupting maize plant defenses and by excluding other fungi from necrotic tissues and crop residues. This is the first report of natural products from C. graminicola, as well as the production of monorden and monocillins by a pathogen of cereals.

Because switchgrass is a native plant, it has been suggested that disease problems will be minimal, but little research in this area has been conducted. Recently, outbreaks of switchgrass anthracnose disease have been reported from the northeastern United States. Incidences of switchgrass anthracnose are known in North America since 1886 through herbarium specimens and disease reports, but the causal agent of this disease has never been experimentally determined or taxonomically evaluated. In the present work, we evaluate the causal agent of switchgrass anthracnose, a new species we describe as Colletotrichum navitas (navitas = Latin for energy). Multilocus molecular phylogenetics and morphological characters show C. navitas is a novel species in the falcate-spored graminicolous group of the genus Colletotrichum; it is most closely related to the corn anthracnose pathogen Colletotrichum graminicola. We present a formal description and illustrations for C. navitas and provide experimental confirmation that this organism is responsible for switchgrass anthracnose disease.

Diabrotica virgifera (the western corn rootworm) is a severe agricultural pest that lives subterraneously during its pre-imaginal stages and succumbs to high levels of pre-imaginal mortality from unknown agents. The guts of 1500 field-collected arthropod predators were analyzed for D. virgifera-specific DNA sequences using quantitative polymerase chain reaction (qPCR). These gut analyses were used to generate relative and taxon-specific prey consumption indices for the major predator taxa and to determine relative consumption levels during D. virgifera egg and larval stages by predator feeding guilds. Laboratory feeding assays were used to determine the meal size consumed during 5 min and digestion rates of D. virgifera DNA of four predators abundant in D. virgifera-infested cornfields. More than 17 taxa consumed D. virgifera in the field. Harvestmen and small rove beetles were the most abundant predators captured, and the most frequent predators within the community to consume D. virgifera. The largest proportions of individual species' populations testing positive for D. virgifera DNA were found in ground beetles (Scarites quadriceps and Poecilus chalcites) and spiders, wolf spiders, and predaceous mites. Because of the longer duration of the egg stage, significantly more predators consumed D. virgifera eggs than larvae, but a similar proportion of the predator community fed on eggs and larvae. Predators with sucking mouthparts had a higher consumption index than chewing predators. Laboratory assays confirmed that sucking predators consume more D. virgifera DNA during 5 min than the chewing predators, and all four predators digested this DNA at a similar rate. This research substantiates that a diverse community of soil-dwelling and subterranean predators contribute to the high level of mortality incurred by D. virgifera in cornfields (699% pre-adult mortality). Moreover, qPCR is a useful tool for describing trophic relationships within subterranean food webs, a crucial step in determining the relative contributions of a diverse predator community to the population dynamics of an herbivorous arthropod.

However, little is known about the composition of plant species on these conservation grasslands or their potential for ethanol production. Our objective was to assess the potential of CRP and other conservation grasslands for biofuel production, describing the relationships of plant species richness and tall native C sub(4) prairie grass abundance with plant chemical composition and the resulting potential ethanol yield. We determined plant species composition and diversity at multiple scales with the modified Whittaker plot technique, aboveground biomass, plant chemical composition, and potential ethanol yield at 34 sites across the major ecological regions of the northeastern USA. Conservation grasslands with higher numbers of plant species had lower biomass yields and a lower ethanol yield per unit biomass compared with sites with fewer species. Thus, biofuel yield per unit land area decreased by 77% as plant species richness increased from 3 to 12.8 species per m super(2). We found that, as tall native C sub(4) prairie grass abundance increased from 1.7% to 81.6%, the number of plant species decreased and aboveground biomass per unit land area and ethanol yield per unit biomass increased resulting in a 500% increased biofuel yield per unit land area. Plant species richness and composition are key determinants of biomass and ethanol yields from conservation grasslands and have implications for low-input high-diversity systems. Designing systems to include a large proportion of species with undesirable fermentation characteristics could reduce ethanol yields.

AN - 21051063; 11324142 AB - Stream and river ecosystems have suffered extensive degradation, and billions are expended annually on restoration efforts. However, few of these projects are monitored, and restoration effectiveness is often unknown. Consequently, there is a poor scientific foundation for restoration designs. Since many stream restoration efforts are at least partially targeted at controlling erosion of channel banks and beds, the effects of a large-scale, long-term stream erosion control effort in six Mississippi watersheds was assessed using 10-16 years of suspended sediment and water discharge records. Flow-adjusted suspended sediment concentrations showed no trends in five of the watersheds and a slight downward trend in one watershed, which was treated with small reservoirs as well as bed and bank erosion protection. Results indicate the inability of orthodox stream management structures (weirs and bank protection) to reduce watershed sediment yield and the need for a stronger scientific basis for stream restoration.

All sieved fractions except for the pan fraction, constituting about 90% of original mass, were then winnowed with an air blast seed cleaner. Sieving was effective in producing fractions with varying composition. As the particle size decreased, protein and ash contents increased, and total carbohydrate (CHO) decreased. Winnowing sieved fractions was also effective in shifting composition, particularly for larger particle classes. Heavy sub-fractions were enriched in protein, oil and ash, while light sub-fractions were enriched for CHO. For protein, the combination of the two procedures resulted in a maximum 56.4% reduction in a fraction and maximum 60.2% increase in another fraction. As airflow velocity increased, light sub-fraction mass increased, while the compositional difference between the heavy and light sub-fractions decreased. Winnowing three times at a lower velocity was as effective as winnowing one time at a medium velocity. Winnowing the whole DDGS was much less effective than winnowing sieved fractions in changing composition, but sieving winnowed fractions was more effective than sieving whole DDGS. The two combination sequences gave comparable overall effects but sieving followed by winnowing is recommended because it requires less time. Regardless of combinational sequence, the second procedure was more effective in shifting composition than the first procedure.

Fifteen different conditions for pretreatment were examined in a 2 super(3) full factorial design with six axial points. Temperatures ranged from 132 to 180 C, time from 10 to 90 min and oxalic acid loadings from 0.01 to 0.038 g/g solids. Separate maxima were found for enzymatic saccharification and hemicellulose fermentation, respectively, with the condition for maximum saccharification being significantly more severe. Ethanol production was affected by reaction temperature more than by oxalic acid and reaction time over the ranges examined. The effect of reaction temperature was significant at a 95% confidence level in its effect on ethanol production. Oxalic acid and reaction time were statistically significant at the 90% level. The highest ethanol concentration (20 g/l) was obtained after 48 h with an ethanol volumetric production rate of 0.42 g ethanol l super(-1) h super(-1). The ethanol yield after SSF with P. stipitis was significantly higher than predicted by sequential saccharification and fermentation of substrate pretreated under the same condition. This was attributed to the secretion of b-glucosidase by P. stipitis. During SSF, free extracellular b-glucosidase activity was 1.30 pNPG U/g with P. stipitis, while saccharification without the yeast was 0.66 pNPG U/g.

It is clear that biofuels can help meet some of the increasing need for energy. Theoretically, these can be produced from a variety of biological materials, including agricultural residues (such as corn stover and wheat straw), perennial grasses, legumes, algae, and other biological materials. Currently, however, the most heavily utilized material is corn starch. Industrial fuel ethanol production in the US primarily uses corn, because it is readily converted into fuel at a relatively low cost compared to other biomass sources. The production of corn-based ethanol in the US is dramatically increasing. As the industry continues to grow, the amount of byproducts and coproducts also increases. At the moment, the nonfermentable residues (which are dried and sold as distillers dried grains with solubles - DDGS) are utilized only as livestock feed. The sale of coproducts provides ethanol processors with a substantial revenue source and significantly increases the profitability of the production process. Even though these materials are used to feed animals in local markets, as the size and scope of the industry continues to grow, the need to ship large quantities of coproducts grows as well. This includes both domestic as well as international transportation. Value-added processing options offer the potential to increase the sustainability of each ethanol plant, and thus the industry overall. However, implementation of new technologies will be dependent upon how their costs interact with current processing costs and the logistics of coproduct deliveries. The objective of this study was to examine some of these issues by developing a computer model to determine potential cost ramifications of using various alternative technologies during ethanol processing. This paper focuses specifically on adding a densification unit operation (i.e., pelleting) to produce value-added DDGS at a fuel ethanol manufacturing plant. We have examined the economic implications of pelleting DDGS for varying DDGS production rates (100-1000 tons/d) and pelleting rates (0-100%), for a series of DDGS sales prices ($50-$200/ton). As the proportion of pelleting increases, the cost of transporting DDGS to distant markets drastically declines, because the rail cars can be filled to capacity. For example, at a DDGS sales price of $50/ton, 100% pelleting will reduce shipping costs (both direct and indirect) by 89% compared to shipping the DDGS in bulk form (i.e., no pelleting), whereas at a DDGS sales price of $200/ton, it will reduce costs by over 96%. It is clear that the sustainability of the ethanol industry can be improved by implementing pelleting technology for the coproducts, especially at those plants that ship their DDGS via rail.

We hypothesized that decreases in species richness and abundance are correlated with increasing prevalence of these two species. Therefore, our objectives were to determine whether there are patterns in examined vegetation; how dominant species contribute to these patterns; and how patterns differ between grazed and ungrazed vegetation. We determined that protection from grazing increased species richness. Grazing significantly changed composition through decreasing total plant, forb, grass and F. valesiaca covers, while substantially increasing T. sipyleus cover. Topography, soil and grazing appear to impact the dominance of plant communities where F. valesiaca and T. sipyleus prevail. These two dominant species had a significant effect in shaping vegetation patterns. Based on regression analysis, alterations in species richness with changes in cover of forbs and shrubs were evident, and spatial heterogeneity of F. valesiaca and T. sipyleus indicated unstable vegetative patterns in heavily grazed pastures and successional changes in protected pastures. Our study results identify F. valesiaca and T. sipyleus as indicator species of vegetation suppression in condition assessments of degraded steppe rangelands.

Gram-negative bacteria, which express the pro- inflammatory molecule lipopolysaccharide (LPS), are responsible for the majority of acute clinical cases of mastitis. Previous studies have identified differential susceptibility of human and bovine endothelial cells (EC) to the pro-inflammatory and injury-inducing effects of LPS. The Toll-like receptor (TLR)-4 signaling pathway, which is activated by LPS, has been well studied in humans, but not in ruminants. Human myeloid differentiation-factor 88 (MyD88) and TIR-domain containing adaptor protein (TIRAP) are critical proteins in the LPS-induced NF- Kappa B and apoptotic signaling pathways. To assess the role of the bovine orthologs of these proteins in bovine TLR-4 signaling, dominant-negative constructs were expressed in bovine EC, and LPS- induced NF- Kappa B activation and apoptosis evaluated. The results from this study indicate that bovine MyD88 and TIRAP play functional roles in transducing LPS signaling from TLR-4 to downstream effector molecules involved in NF- Kappa B activation, and that TIRAP promotes apoptotic signaling.Original Abstract: la mammite est une maladie prevalente du betail laitier. Les bacteries Gram negatives, qui liberent la molecule pro-inflammatoire lipopolyoside (LPS), produisent la plupart des cas cliniques de mammite. Des etudes anterieures ont identifie, entre les cellules endotheliales (CE) humaines et bovines, une susceptibilite differenciee aux effets deleteres du LPS. la voie d'activation du recepteur de type Toll (TLR)-4, activee par le LPS, a ete bien etudiee chez l'homme mais pas encore chez les ruminants. le facteur de differenciation myeloiede humain 88 (MyD88) et la "TIR-domain containing adaptor protein (TIRAP)" sont des proteines essentielles aux voies du NF-[kappa]B induites par le LPS ainsi que de la signalisation apoptotique. Afin d'evaluer le role des orthologues bovins de ces proteines dans la signalisation TLR-4, des constructions dominantes-negatives ont ete exprimees dans les CE bovines, et l'activation du NF-[kappa]B induit par le LPS, ainsi que l'apoptose, ont ete evaluees.

This study assessed the morphological and molecular variability of five widespread CFR-causing fungi: Phyllosticta vaccinii, Coleophoma empetri, Colletotrichum acutatum, Colletotrichum gloeosporioides and Physalospora vaccinii. Although the majority of isolates had morphological characteristics consistent with published descriptions, some were atypical. For example, non-chromogenic isolates of C. acutatum were recovered from British Columbia and white isolates of Physalospora vaccinii were recovered in addition to the more common dark isolates. On the basis of sequence analysis of the ITS and large subunit rDNA (LSU), it appears that Phyllosticta vaccinii, C. empetri, C. gloeosporioides and C. acutatum are genetically uniform on cranberry in North America. This suggests the possibility that these fungal species were introduced to cultivated cranberries and concomitantly moved with planting material to new locations. In contrast, white isolates of Physalospora had ITS and LSU sequences distinct from those of their dark counterparts, with phylogenetic analyses suggesting that these isolates represent either different species or distinct members of highly divergent populations. Taxonomic placement of all species based on phylogenetic relationships was consistent with morphological placement, with the exception of Physalospora vaccinii. Unlike other Physalospora species, CFR isolates of Physalospora vaccinii were not allied with the Xylariomycetidae; instead, these fungi were members of the Sordariomycetidae. A deeper taxonomic analysis is needed to resolve this inconsistency in familial affiliation.

As the principal precursor of IPM, the integrated control concept formulated the economic theory behind pest management decisions and specified an applied methodology for carrying out pest control. Sampling, economic thresholds and selective insecticides were three of the critical elements of that methodology and are now considered indispensable to the goals of IPM. We examine each of these elements in the context of contemporaneous information as well as accumulated experience and knowledge required for their skillful implementation in an IPM program. We conclude that while IPM is principally about integrating control tactics into an effective and sustainable approach to pest control, this overarching goal can only be achieved through well-trained practitioners, knowledgeable of the tenets conceived in the integrated control concept that ultimately yield informed pest management.

One of the least explored processes is the role of subsurface flow. Rain or irrigation water entering the soil profile either accrues to groundwater or exits at some point downslope as seepage. In the latter case, the positive water pressure may lead to detachment of soil particles, aggregates, or bulk soil, that often is a prelude to incipient rilling or gullying. This article concerns the analysis of seepage to ditches with a water level lower than the adjacent field water table and the hydraulic pressures near the ditches in order to assess their contributing role in gully development. The approach taken is to analyze the subsurface flow regime under steady-state conditions using the theory of conformal transformations. First, seepage to a fully filled circular drain in a homogeneous isotropic layer overlaying an impermeable layer was analyzed. Subsequently, the case of drainage to a ditch partially filled with water and the effect of a buffer strip adjacent to the ditch on seepage reduction were studied using the same methodology. Two approaches were considered to approximate the water level in the buffer strip: (1) a confined boundary represented by a straight line between the ditch water level and the field surface water level; and (2) a free boundary in which the groundwater level was approximated by the pressure potential relationship for flow from a ponded surface area to a sink placed at the surface at a distance equal to the width of the buffer strip. The latter analysis yielded explicit expressions of seepage, and the groundwater hydraulic and stream potential functions in terms of the spatial coordinates. This relationship should facilitate the analysis of the role of the subsurface water regime on seepage, soil erosion, and gully development. Published in 2009 by John Wiley & Sons, Ltd.

Experiments were conducted to further examine the morphodynamic behavior of actively migrating headcuts in upland concentrated flows with varying boundary conditions. The effect of soil texture greatly modified the erodibility of the select soils, and headcut migration rates, scour depths, and sediment discharges were correlated to the critical shear stress and erodibility of the select soils. The effect of increasing tailwater height greatly reduced the nappe entry angle at the brink of the headcut, completely arresting the soil erosion processes. Altering subsurface pore-water pressures markedly changed the erodibility coefficients of the select soil, which caused greater headcut migration rates and sediment discharges, yet shallower scour holes, in the presence of a subsurface water table. Current analytic formulations based on jet impingement theory successfully predicted these experimental observations, further demonstrating the utility of such analytic formulations in advancing watershed management technology.

Existing challenge study protocols and those under development differ markedly in terms of experimental design and the acceptance criteria under which a RTE food is determined not to support L. monocytogenes growth. Consequently, the protocols differ substantially with respect to the probability of incorrectly determining that growth occurs and the statistical power to detect growth if it does occur. Applying a fixed acceptance criteria exceedance value (e.g., less than a 0.5 log sub(10) or 1 log sub(10) increase) to distinguish real growth from quantitative measurement uncertainty over different experimental designs and/or measurement uncertainty values implies highly inconsistent type I error (a) probabilities. None of the L. monocytogenes growth challenge study designs currently being considered are likely to provide an F-test with a = 0.05 and power >= 0.8 to detect a 1 log sub(10) increase in mean concentration over the entire range of measurement uncertainty values for enumeration of L. monocytogenes reported in food samples in a validation study of ISO Method 11290-2.

A combined physical-chemical nonequilibrium (PCNE) model was therefore used to describe general mass transport. The model partitions the pore space into ''mobile'' and ''immobile'' flow regions with first-order mass transfer between these two regions (i.e, ''physical'' nonequilibrium or PNE). Partitioning between the aqueous and solid phases can either proceed as an equilibrium or a first-order process (i.e, ''chemical'' nonequilibrium or CNE) for both the mobile and immobile regions. An analytical solution for the PCNE model is obtained using iterated Laplace transforms. This solution complements earlier semi-analytical and numerical approaches to model solute transport with the PCNE model. The impact of selected model parameters on solute breakthrough curves is illustrated. As is well known, nonequilibrium results in earlier solute breakthrough with increased tailing. The PCNE model allows greater flexibility to describe this trend; for example, a closer resemblance between solute input and effluent pulse. Expressions for moments and transfer functions are presented to facilitate the analytical use of the PCNE model. Contours of mean breakthrough time, variance, and spread of the colloid breakthrough curves as a function of PNE and CNE parameters demonstrate the utility of a model that accounts for both physical and chemical nonequilibrium processes. The model is applied to describe representative colloid breakthrough curves in Ottawa sands reported by Bradford et al. (2002). An equilibrium model provided a good description of breakthrough curves for the bromide tracer but could not adequately describe the colloid data. A considerably better description was provide by the simple CNE model but the best description, especially for the larger 3.2-?m colloids, was provided by the PCNE model.

10969743 AB - Improved wildland fire emission inventory methods are needed to support air quality forecasting and guide the development of air shed management strategies. Air quality forecasting requires dynamic fire emission estimates that are generated in a timely manner to support real-time operations. In the regulatory and planning realm, emission inventories are essential for quantitatively assessing the contribution of wildfire to air pollution. The development of wildland fire emission inventories depends on burned area as a critical input. This study presents a Moderate Resolution Imaging Spectroradiometer (MODIS) - direct broadcast (DB) burned area mapping algorithm designed to support air quality forecasting and emission inventory development. The algorithm combines active fire locations and single satellite scene burn scar detections to provide a rapid yet robust mapping of burned area. Using the U.S. Forest Service Fire Sciences Laboratory (FiSL) MODIS-DB receiving station in Missoula, Montana, the algorithm provided daily measurements of burned area for wildfire events in the western U.S. in 2006 and 2007. We evaluated the algorithm's fire detection rate and burned area mapping using fire perimeter data and burn scar information derived from high resolution satellite imagery. The FiSL MODIS-DB system detected 87% of all reference fires >4 km super(2), and 93% of all reference fires >10 km super(2). The burned area was highly correlated (R super(2)=0.93) with a high resolution imagery reference burn scar dataset, but exhibited a large over estimation of burned area (56%). The reference burn scar dataset was used to calibrate the algorithm response and quantify the uncertainty in the burned area measurement at the fire incident level. An objective, empirical error based approach was employed to quantify the uncertainty of our burned area measurement and provide a metric that is meaningful in context of remotely sensed burned area and emission inventories. The algorithm uncertainty is +/-36% for fires 50 km super(2) in size, improving to + /-31% at a fire size of 100 km super(2). Fires in this size range account for a substantial portion of burned area in the western U.S. (77% of burned area is due to fires >50 km super(2), and 66% results from fires >100 km super(2)). The dominance of these large wildfires in burned area, duration, and emissions makes these events a significant concern of air quality forecasters and regulators. With daily coverage at 1-km super(2) spatial resolution, and a quantified measurement uncertainty, the burned area mapping algorithm presented in this paper is well suited for the development of wildfire emission inventories. Furthermore, the algorithm's DB implementation enables time sensitive burned area mapping to support operational air quality forecasting.

AN - 67648328; 19643074 AB - Biomarkers in urine can provide useful information about the bioactivation of chemical carcinogens and can be used to investigate the chemoprotective properties of dietary nutrients. N-Nitrosoproline (NPRO) excretion has been used as an index for endogenous nitrosation. In vitro and animal studies have reported that compounds in garlic may suppress nitrosation and inhibit carcinogenesis. We present a new method for extraction and sensitive detection of both NPRO and N-acetyl-S-allylcysteine from urine. The latter is a metabolite of S-allylcysteine, which is found in garlic. Urine was acidified and the organic acids were extracted by reversed-phase extraction (RP-SPE) and use of a polymeric weak anion exchange (WAX-SPE) resin. NPRO was quantified by isotope dilution gas chromatography-mass spectrometry (GC-MS) using [13C5]NPRO and N-nitrosopipecolinic acid (NPIC) as internal standards. This method was used to analyze urine samples from a study that was designed to test whether garlic supplementation inhibits NPRO synthesis. Using this method, 2.4 to 46.0 ng NPRO/ml urine was detected. The method is straightforward and reliable, and it can be performed with readily available GC-MS instruments. N-Acetyl-S-allylcysteine was quantified in the same fraction and detectable at levels of 4.1 to 176.4 ng/ml urine. The results suggest that 3 to 5 g of garlic supplements inhibited NPRO synthesis to an extent similar to a 0.5-g dose of ascorbic acid or a commercial supplement of aged garlic extract. Urinary NPRO concentration was inversely associated with the N-acetyl-S-allylcysteine concentration. It is possible that allyl sulfur compounds found in garlic may inhibit nitrosation in humans.

AN - 66634983; 19695277 AB - Numerous metabolism studies have demonstrated that the toxic contaminant 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) is poorly metabolized. A hallmark feature of TCDD exposure is induction of hepatic CYP1A2 and subsequent sequestration leading to high liver-to-fat concentration ratios. This study was initiated to determine whether TCDD was inherently poorly metabolized or unavailable for metabolism because of sequestration to CYP1A2. [(3)H]TCDD was administered as a single, oral dose (0.1 and 10 microg/kg) to 12 male C57BL/6N mice or 12 CYP1A2 (-/-) mice. At 96 h, less than 5% of the dose was eliminated in the urine of all groups, and TCDD detected in urine was bound to mouse major urinary protein (mMUP). Feces were the major elimination pathway (24-31% of dose), and fecal extracts and non-extractables were quantitated by HPLC for metabolites. No great differences in urinary or fecal elimination (% dose) were observed between the high and low dose treatments. TCDD concentrations were the highest in adipose tissue for CYP1A2 knockout mice but in liver for C57BL/6N mice supporting the role of hepatic CYP1A2 in the sequestration of TCDD. Overall metabolism between parental and knockout strains showed no statistical differences at either the high or low doses. The data suggested that metabolism of TCDD is inherently slow, due principally to CYP1A1, and that hepatic CYP1A2 is not an active participant in the metabolism of TCDD in male mice.

In this study, five sites representing a downstream progression of forested uplands underlain by resistant sandstone to karst lowlands with agricultural, urban and mixed land-use were established in Spring Creek, a 201 km2 mixed land-use watershed in central Pennsylvania, USA. At each site, stream water was monitored during six storm events in 2005 to assess changes in stable isotopes of NO3- (15N-NO3- and 18O-NO3-) and water (18O-H2O) from baseflow to peakflow. Peakflow fractions of event NO3- and event water were then computed using two-component mixing models to elucidate NO3- flow pathway differences among the five sites. For the forested upland site, storm size appeared to affect NO3- sources and flow pathways. During small storms (35 mm rainfall), event NO3- fractions were less than event water fractions at peakflow suggesting that NO3- was flushed from stored sources via shallow subsurface flow pathways. For the urbanized site, wash-off of atmospheric NO3- was an important NO3- source at peakflow, especially during short-duration storms where event water contributions indicated the prevalence of overland flow. In the karst lowlands, very low fractions of event water and even lower fractions of event NO3- at peakflow suggested the dominance of ground water flow pathways during storms. These ground water flow pathways likely flushed stored NO3- sources into the stream, while deep soils in the karst lowlands also may have promoted NO3- assimilation. The results of this study illustrated how NO3- isotopes and 18O-H2O could be combined to show key differences in water and NO3- delivery between forested uplands, karst valleys and fully urbanized watersheds.

11180886 AB - Contamination of maize (Zea mays L.) grain with aflatoxin, produced by the fungus Aspergillus flavus Link: Fries, or fumonisin, produced by the fungus Fusarium verticillioides (Saccardo) Nirenberg (Syn F. moniliforme Sheldon), greatly reduces its value and marketability. Host resistance to fungal infection and mycotoxin accumulation is considered a highly desirable way to reduce losses of both aflatoxin and fumonisin. Maize germplasm lines with resistance to aflatoxin accumulation have been developed in Mississippi. Three of the aflatoxin-resistant lines and five additional lines were used as parents to produce a diallel cross. The diallel cross was evaluated for fumonisin accumulation in field tests conducted in Mississippi in 2007 and 2008. General combining ability (GCA) was a highly significant source of variation in both 2007 and 2008, but specific combining ability (SCA) was not significant. GCA effects for reduced fumonisin levels were highly significant for Mp715, Mp717, and GA209. Mp715 and Mp717 were developed and released as sources of resistance to aflatoxin contamination and exhibit resistance as inbred lines and in hybrid combinations. These lines should be useful in developing maize lines and hybrids with resistance to both fumonisin and aflatoxin accumulation in grain.

A reasonably parsimonious model used eight predictors to describe aspen's climate profile. Classification errors averaged 4.5%, most of which were errors of commission. The model was driven primarily by three variables: an annual dryness index, the ratio of summer to annual precipitation, and an interaction of growing season precipitation with the summer-winter temperature differential. Projecting the contemporary climate profile into the future climate provided by three General Circulation Models and two scenarios (SRES A2 and either B1 or B2) suggested that the area occupied by the profile should diminish rapidly over the course of the century, 6-41% by the decade surrounding 2030, 40-75% for that surrounding 2060, and 46-94% for 2090. The relevance of the climate profile to understanding climate-based responses is illustrated by relating trends in climate to the recent incidence of sudden aspen dieback that has plagued portions of the aspen distribution. Of the eight variables in the profile, four reached extreme values during 2000-2003, the period immediately preceding the appearance of damage in aerial surveys.

Fuel treatments involving mechanical and prescribed fire methods can reduce surface as well as canopy fuel loads. Mastication is a mechanical method which shreds smaller trees and brush onto the surface fuel layer. Little data exist quantifying masticated fuel beds. Despite the paucity of data on masticated fuels, land managers desire fuel loading, potential fire behavior and fire effects such as tree mortality information for masticated areas. In this study we measured fuel characteristics before and after mastication and mastication plus prescribed burn treatments in a 25-year old ponderosa pine (Pinus ponderosa C. Lawson) plantation. In addition to surface fuel characteristics and tree data collection, bulk density samples were gathered for masticated material. Regressions were created predicting masticated fuel loading from masticated fuel bed depth. Total masticated fuel load prior to fire treatment ranged from 25.9 to 42.9Mgha super(-) super(1), and the bulk density of masticated fuel was 125kgm super(-) super(3). Mastication treatment alone showed increases in most surface fuel loadings and decreases in canopy fuel loads. Masticated treatment in conjunction with prescribed burning reduced both surface and canopy fuel loads. Detailed information on fuel structure in masticated areas will allow for better predictions of fire behavior and fire effects for fire in masticated fuel types. Understanding potential fire behavior and fire effects associated with masticated fuels will allow managers to make decisions on the possibility of mastication to create fuel breaks or enhance forest health.

13368697 AB - Annual precipitation in the central and southern warm-desert region of North America is distributed climatologically between summer and winter periods with two prominent dry periods between them. We used energy and carbon dioxide (CO2) fluxes from eddy covariance along with standard meteorological and soil moisture measurements at a semiarid savanna in southern Arizona, United States, to better understand the consequences of warm or cool season drought on ecosystem CO2 exchange in these bimodally forced water-limited regions. Over the last 100 years, this historic grassland has converted to a savanna by the encroachment of the native mesquite tree (Prosopis velutina Woot.). During each of the 4 years of observation (2004-2007), annual precipitation (P) was below average, but monsoon (July-September) P was both above and below average while cool-season (December-March) P was always less than average by varying degrees. The ecosystem was a net source of CO2 to the atmosphere, ranging from 14 to 95 g C m-2 yr-1 with the strength of the source increasing with decreasing precipitation. When the rainfall was closest to the long-term average in its distribution and amount, the ecosystem was essentially carbon neutral. Summer drought resulted in increased carbon losses due mainly to a shortening of the growing season and the length of time later in the season when photosynthetic gain exceeds respiration loss. Severe cool season drought led to decreased spring carbon uptake and seemingly enhanced summer respiration, resulting in conditions that led to the greatest annual net carbon loss.

Although poultry litter can be moved off the farm and traded as fertilizer, its transportation becomes less economical with increasing distances from the farm. Thus, new litter management alternatives are needed to reduce the environmental impact of P litter application to land. This paper summarizes established and emerging alternative technologies in the U.S. that facilitate handling, concentration, and transporting of litter P. Furthermore, it examines the potential integration of technologies into poultry litter management systems that could reduce poultry litter volume and increase P content in litter byproducts.

This report highlights the state of current issues, technical knowledge, and remaining challenges to be addressed in evaluating the impacts of airborne microorganisms, dusts, and odorants on animals and workers at animal production facilities and nearby communities. Reports documenting bioaerosol measurements illustrate some of the technical issues related to sample collection, analysis, as well as dispersion and transport to off-farm locations. Approaches to analysis, mitigation and modeling transport are discussed in the context of the risk reduction and management of airborne spread of bioaerosols from animal operations. The need for standardization and validation of bioaerosol collection and analytical techniques for indoor as well as outdoor animal agriculture settings is critical to evaluation of health effects from modern animal production systems that are increasingly situated near communities.

Whereas photographic equipment and electronics have been evolving rapidly, photographic monitoring methods for rangelands have changed little over time because each picture is a compromise between resolution and area covered. Advances in image sensors, storage media, and image-processing software allow enormous amounts of information to be collected efficiently and inexpensively, so multiple pictures taken at full zoom can be combined into a single high-resolution panoramic image. This project was initiated to integrate very-high-resolution panoramic images with conventional rangeland monitoring methods addressing three resource management categories: riparian areas, wildlife, and invasive species.

The objective of this study was to examine the effects of intensity and season of browsing on annual height growth of aspen suckers. The goal was to aid development of livestock grazing strategies to restore stands in decline due to excessive livestock browsing. We implemented 33 combinations of intensity and season of browse on aspen suckers in three aspen stands on Eagle Lake Range District, Lassen National Forest, California, USA, during 2003 and 2004. Greatest growth was on suckers with no terminal leader browse and less than or equal to 25% of biomass removed from branches. Lowest growth occurred when 90% of terminal leader length and 50% of branch biomass was removed. Growth was most negatively affected by browse on terminal leader. Growth was lowest for suckers browsed midseason only and suckers browsed both early and midseason. Occurrence of conifer in the stand overstory significantly reduced sucker growth. Managers should minimize browse on terminal leaders, midseason browse over consecutive years, and repeated browse during a growing season.

We are exploring the regulation of heartwood production by identifying genes associated with the transition from sapwood to heartwood. Previous microarray data indicated that heartwood formation may be related to programmed cell death (PCD). To test this hypothesis, we analyzed the region of heartwood formation in walnut stems (i.e., the transition zone, TZ) for the expression of 80 ESTs putatively associated with PCD. Semi-quantitative RT-PCR and real-time PCR was performed to detect the expression changes in candidate genes in the TZ and sapwood of trees harvested in summer and fall. The results revealed that the transcript of a clone that encodes a presumed homeobox protein knotted-1-like 3 (KNAT3) was highly expressed in the TZ when compared with other tissues. Analysis of the full-length coding sequence revealed that the black walnut gene contains regions with 67% similarity to Knox1 and Knox2 domains from the Arabidopsis thaliana KNAT3, as well as a putative homeodomain known to be a transcription factor in other plants. JnKNAT3-like transcript was detected in the pith meristem, roots, embryogenic callus, vascular cambium, female flowers, male flowers, green leaves, and partially and fully senescent leaves of black walnut, although transcript abundance varied considerably among tissues. These analyses may provide insight into the mechanism regulating heartwood formation in walnut and other hardwood trees.

For each step in the continuum, we examine the roles, responsibilities, and information needs of the Animal and Plant Health Inspection Service and other agencies involved in plant biosecurity. Both costs and information needs increase dramatically as a pest penetrates deeper into the continuum. To help meet these information needs, we propose a cyberinfrastructure for plant biosecurity to link phytosanitary agencies, researchers, and stakeholders, including industry and the public. The cyberinfrastructure should facilitate data collection, data integration, risk analysis, and reporting. We also emphasize the role of private industry in providing critical data for surveillance. We anticipate that this article will provide agricultural stakeholders, including scientists, with a better understanding of the information needs of phytosanitary organizations, and will ultimately lead to a more coordinated biosecurity effort.

Cytochrome b is a critical intermediate in a mitochondrial death pathway. To reveal whether cytochrome b of the mosquito Aedes aegypti (L.) (Diptera: Culicidae) (AeaCytB) is developmentally regulated, we used real-time quantitative polymerase chain reaction (qPCR) to examine AeaCytB gene expression levels in different developmental stages of Ae. aegypti. The qPCR showed that AeaCytB was expressed in each developmental stage, with peaks at first and second instars and was highly expressed in teneral male and female Ae. aegypti adults. Because mitochondrial genes exist as multiple copies, AeaCytB has much higher expression levels in all developmental stages in Ae. aegypti compared with nuclear genes. We also investigated the effect of abiotic environmental factors (e.g., high temperatures, ultraviolet radiation, and pesticide) on AeaCytB gene expression. Taken together, these results suggest that AeaCytB gene plays an important role in the development of Ae. aegypti and its response to environmental stress.

Hence, there is a need to develop improved methods for targeted management of nutria. We screened 14 olfactory cues as potential lures for nutria, first in controlled settings and then in the field, to see if nutria capture rates using foothold traps would increase. In Y-maze trials, nutria most frequently selected olfactory cues of a synthetic formulation of nutria anal-gland secretion and nutria fur extract. We examined the 3 most selected attractants in Y-maze trials and female nutria urine under field conditions to compare trapping success over untreated traps. Capture probability was nearly 2.5 times greater for fur wash than control and 2 times greater for urine than control (relative risk = 2.43 and 2.01, respectively). The results suggest that use of semiochemicals and synthetic formulations of semiochemicals increased nutria trapping success. Development and use of effective synthetic semiochemicals could benefit resource managers nationwide who are responsible for reducing damage caused by this invasive herbivore.

We examined nest-site selection and nest survival of the Black-chinned Hummingbird (Archilochus alexandri) in New Mexico riparian forests treated or not for fuel reduction. In untreated plots the hummingbirds frequently nested in exotic trees such as saltcedar (Tamarix spp.) and Russian olive (Eleagnus angustifolia). Following fuel reduction, they increased use of cottonwood (Populus deltoides ssp. wislizenii) as a nest substrate and nested at greater heights. Though fuel reduction influenced habitat and nest-site selection, it did not immediately affect nest survival. A logistic exposure model containing effects of year and interaction of nest height and substrate explained nest survival better than did other models. Estimates of daily nest-survival rates from this model varied by year from 0.970 (95% CI: 0.949- 0.982) to 0.992 (95% CI: 0.983-0.996), corresponding with period survival rates of 31% (95% CI: 13.7%-50.1%) to 73% (95% CI: 52.1%-85.9%). In addition, in all substrates except saltcedar, nest survival decreased with nest height. Our relatively high nest-survival estimates suggest that the riparian forest along the Middle Rio Grande provides high-quality nesting habitat for this species. Fuel reduction, however, reduces nest-site availability and can lower nest survival by removing potential nest sites in the forest understory, forcing hummingbirds to nest at greater heights where predation risk is higher.

AN - 733599966; 19891833 AB - This study deals with the rapid detection and differentiation of Escherichia coli, Salmonella, and Campylobacter, which are the most commonly identified commensal and pathogenic bacteria in foods, using fluorescence spectroscopy and multivariate analysis. Each bacterial sample cultured under controlled conditions was diluted in physiologic saline for analysis. Fluorescence spectra were collected over a range of 200-700 nm with 0.5 nm intervals on the PerkinElmer Fluorescence Spectrometer. The synchronous scan technique was employed to find the optimum excitation (lambda(ex)) and emission (lambda(em)) wavelengths for individual bacteria with the wavelength interval (Deltalambda) being varied from 10 to 200 nm. The synchronous spectra and two-dimensional plots showed two maximum lambda(ex) values at 225 nm and 280 nm and one maximum lambda(em) at 335-345 nm (lambda(em) = lambda(ex) + Deltalambda), which correspond to the lambda(ex) = 225 nm, Deltalambda = 110-120 nm, and lambda(ex) = 280 nm, Deltalambda = 60-65 nm. For all three bacterial genera, the same synchronous scan results were obtained. The emission spectra from the three bacteria groups were very similar, creating difficulty in classification. However, the application of principal component analysis (PCA) to the fluorescence spectra resulted in successful classification of the bacteria by their genus as well as determining their concentration. The detection limit was approximately 10(3)-10(4) cells/mL for each bacterial sample. These results demonstrated that fluorescence spectroscopy, when coupled with PCA processing, has the potential to detect and to classify bacterial pathogens in liquids. The methodology is rapid (>10 min), inexpensive, and requires minimal sample preparation compared to standard analytical methods for bacterial detection.

AN - 67582511; 19442517 AB - Slow pyrolysis or carbonization promotes the conversion of animal manures such as swine manure into charcoal. In this paper, the carbonizing kinetics of swine solids taken from different treatment stages were investigated with a thermogravimetric analyzer. Compared to their biologically stabilized counterpart (lagoon sludge) with an activation energy of 160 kJ mol(-1), the activation energies for fresh swine solid samples such as homogenized flushed manure and dewatered solids were much lower between 92 and 95 kJ mol(-1). Compared to the kinetics of first order decomposition of cellulose, the pyrolytic decomposition of the swine manures were more complex with the reaction orders varying at 3.7 and 5.0. The two different mathematical methods employed in this paper yielded the similar values of activation energy (E) and pre-exponential factor (A), confirming the validity of these methods. The results of this study provide useful information for development of farm-scale swine solid carbonization process.

AN - 67502530; 19540755 AB - Agricultural by-products represent a considerable quantity of harvested commodity crops. The use of by-products as precursors for the production of widely used adsorbents, such as activated carbons, may impart a value-added component of the overall biomass harvested. Our objective in this paper is to show that flax shive and cotton gin waste can serve as a precursor for activated carbon that can be used for adsorption of trichloroethylene (TCE) from both the liquid and gas phases. Testing was conducted on carbon activated with phosphoric acid or steam. The results show that activated carbon made from flax shive performed better than select commercial activated carbons, especially at higher TCE concentrations. The activation method employed had little effect on TCE adsorption in gas or vapor phase studies but liquid phase studies suggested that steam activation is slightly better than phosphoric acid activation. As expected, the capacity for the activated carbons depended on the fluid phase equilibrium concentration. At a fluid concentration of 2 mg of TCE/L of fluid, the capacity of the steam activated carbon made from flax shive was similar at 64 and 80 mg TCE/g of carbon for the vapor and liquid phases, respectively. Preliminary cost estimates suggest that the production costs of such carbons are $1.50 to $8.90 per kg, depending on activation method and precursor material; steam activation was significantly less expensive than phosphoric acid activation.

Evidence from the National Agricultural Workers Survey AN - 60330653; 201013830 AB - Ample scholarship suggests that unauthorized immigrants are more likely to face occupational hazards because their lack of legal status makes them more vulnerable to workplace abuse. Despite much research documenting how legal status affects wages, employment, and job stability, few studies have empirically analyzed impacts of legal status on the employment conditions of hired farmworkers. In this article we examine whether unauthorized farmworkers are more likely to handle pesticides and receive pesticide training. We use the National Agricultural Workers Survey, a data set that distinguishes between unauthorized, authorized, and citizen workers. Results from descriptive statistics and multivariate analyses suggest, contrary to expectation, that unauthorized legal status is associated with a reduced likelihood of handling pesticides or receiving training for pesticides. This finding is bolstered by results for control variables associated with unauthorized status, such as age and U.S. agricultural employment experience. Taken together, the results are consistent with labor market segmentation theory that suggests jobs encompassing occupational hazards are allocated to or held by more experienced workers who are better compensated for the risks they undertake.

This paper studies bidder behavior in an innovative auction-based program in which farmers compete to sell and retire the right to develop their land. We derive a reduced-form bidding model that includes private and common values. This model allows us to estimate the role of bidder competition, winner's curse correction, and the underlying distribution of private values. We estimate that the auction enrolled as many as 3,000 acres (12%) more than a take-it-or-leave-it offer would have enrolled for the same budgetary cost. Adapted from the source document.

Applying constructionism to the analysis and design of specific policies, we explored policy options to facilitate cooperation and avert conflict between these stakeholders. Informants displayed three primary frames in discussions of oak conservation: the human-nature relationship, the rights and obligations of property ownership, and the role of policy in social change. Their motivations to conserve oak and preferences for conservation policy stemmed from their differing uses of these frames. Conservation easements, habitat mitigation banking, and voluntary grass-roots initiatives were three types of policy that seemed to accommodate the frames of both owners and natural resource professionals.

Development of management practices to reduce these emissions would have a significant impact on greenhouse gas levels. Non-leguminous cover crops are efficient scavengers of residual soil NO sub(3), thereby reducing leaching losses. However, the effect of a grass cover crop on N sub(2)O emissions from soil receiving liquid swine manure has not been evaluated. This study investigated: (i) the temporal patterns of N sub(2)O emissions following addition of swine manure slurry in a laboratory setting under fluctuating soil moisture regimes; (ii) assessed the potential of a rye (Secale cereale L.) cover crop to decrease N sub(2)O emissions under these conditions; and (iii) quantified field N sub(2)O emissions in response to either spring applied urea ammonium nitrate (UAN) or different rates of fall-applied liquid swine manure, in the presence or absence of a rye/oat winter cover crop. Laboratory experiments investigating cover crop effects N sub(2)O emissions were performed in a controlled environment chamber programmed for a 14h light period, 18 super(o)C day temperature, and 15 super(o)C night temperature. Treatments with or without a living rye cover crop were treated with either: (i) no manure; (ii) a phosphorus-based manure application rate (low manure): or (iii) a nitrogen-based manure application rate (high manure). We observed a significant reduction in N sub(2)O emissions in the presence of the rye cover crop. Field experiments were performed on a fine-loamy soil in Central Iowa from October 12, 2005 to October 2, 2006. We observed no significant effect of the cover crop on cumulative N sub(2)O emissions in the field. The primary factor influencing N sub(2)O emission was N application rate, regardless of form or timing. The response of N sub(2)O emission to N additions was non-linear, with progressively more N sub(2)O emitted with increasing N application. These results indicate that while cover crops have the potential to reduce N sub(2)O emissions, N application rate may be the overriding factor.

The grazing activity of protozoan predators significantly impacts the dynamics, diversification, and evolution of bacterial communities in soil ecosystems. To evade protozoan predation, bacteria employ various defense strategies. Soil-dwelling Pseudomonas fluorescens strains SS101 and SBW25 produce the cyclic lipopeptide surfactants (CLPs) massetolide and viscosin, respectively, in a quorum-sensing-independent manner. In this study, CLP production was shown to protect these bacteria from protozoan predation as, compared to CLP-deficient mutants, strains SS101 and SBW25 exhibited resistance to grazing by Naegleria americana in vitro and superior persistence in soil in the presence of this bacterial predator. In the wheat rhizosphere, CLP-producing strains had a direct deleterious impact on the survival of N. americana. In vitro assays further showed that N. americana was three times more sensitive to viscosin than to massetolide and that exposure of strain SS101 or SBW25 to this protozoan resulted in upregulation of CLP biosynthesis genes. Enhanced expression of the massABC and viscABC genes did not require physical contact between the two organisms as gene expression levels were up to threefold higher in bacterial cells harvested 1 cm from feeding protozoans than in cells collected 4 cm from feeding protozoans. These findings document a new natural function of CLPs and highlight that bacterium-protozoan interactions can result in activation of an antipredator response in prey populations.

The uniformity and recovery rate of water-soluble and insoluble materials of chemical and microbial pesticides with different physical properties discharged from emitters throughout driplines was evaluated. The materials were a water-soluble fluorescent tracer (BSF), a flowable water-dispersible insecticide (Imidacloprid), a suspendible microbial entomopathogenic fungus (EPF), a suspendible microbial soil fungicide (SF), and microbial entomopathogenic nematodes. Treatments also included three different flow capacities of emitters with nominally rated flow capacities of 1.9, 3.8, and 7.6 L h(-1), respectively. Although all materials were readily deliverable through the drip irrigation system, the uniformity of the materials discharged varied with the material formulations and emitter flow capacity. For all emitter flow capacities, BSF had the lowest coefficient of variation, followed by nematodes, Imidacloprid, SF, and EPF. Conversely, the recovery rate of the five materials was in the reverse order. Emitter flow capacity affected the recovery rates of Imidacloprid and SF discharged from the emitters, but not of BSF, EPF and nematodes. Drip irrigation was demonstrated as a viable alternative for application of water-soluble and insoluble materials; however, the discharge rates of EPF and SF must first be determined to compensate for their non-uniformity of delivery and low recovery rates from emitters.

The structural consequences of these processes are used to develop an analytic model based on the concept of branch orders. A set of interrelated equations describe the relationships between structural characteristics, including the distribution of a tree's foliage and the partitioning of the structural components within the crown for the efficient support of that foliage. The foliage biomass distribution in a tree crown and the geometric relationships between the branch orders supporting that distribution are used to define a functional depth that is used to compute an associated functional crown volume. These are computed first for the foliage and then for each of the tree's branch orders. Each functional crown volume is linearly related to its respective biomass component. These consistent linear relationships are demonstrated first with data from pinyon pine and then with data from Utah juniper and Valencia orange trees. The structural changes and associated biomass distribution changes suggest that crown growth is controlled from the outside in, with the resulting structural changes an emergent property of crown adjustment to the annual addition of new foliage. The relationships derived are potentially applicable across a range of additional tree species, in other woody species and applicable over a wide range of locations and conditions.

F. Blake and Shiller, a federally listed candidate endangered species and native to North America and two variants of Hibiscus acetosella Welw. ex Hiern were scarified using sulfuric acid and hot water. The effects of the scarification methods on in vitro and ex vitro germination in both species were evaluated. Sulfuric acid scarification was very effective for in vitro and ex vitro germination of both forms of H. acetosella and H. dasycalyx seeds by dramatically increasing germination rate and decreasing germination time. Acid scarification of H. acetosella seeds for 10, 15, or 20 min resulted in close to 90% germination within a week. Germination rates of about 70% (ex vitro) and 80% (in vitro) were obtained in H. dasycalyx seeds treated with sulfuric acid. Germination rates of 54% (ex vitro) and 95% (in vitro) were achieved when H. dasycalyx seeds were treated with hot water for 5 min, but exposing the seeds for 10, 15, or 20 min produced poor results in H. acetosella and H. dasycalyx as hot water scarification appeared to result in severe injury or death of the embryos. The protocols described here constitute rapid, reliable and simple methods to germinate H. acetosella and H. dasycalyx seeds in vitro and ex vitro. These results can be valuable in commercial productions or research projects. In addition, the in vitro germination of H. dasycalyx can offer a valuable tool in conservation efforts for this threatened species.

Creating RGB images that allow feature classification in areas otherwise obscured by shadow or oversaturation AN - 21326329; 11905632 AB - Shadow often interferes with accurate image analysis. To mitigate shadow effects in near-earth imagery (2m above ground level), we created high dynamic range (HDR) nadir images and used them to measure grassland ground cover. HDR composites were created by merging three differentially exposed images spanning a wide exposure range and resulted in lightened shadows. HDR images showed more detail; reduced the numbers of pure black, pure white, and pixels visually indistinguishable from black and white; reapportioned skewed luma values towards a normal distribution; and increased the Euclidean distance between litter and bare ground RGB values-allowing increased feature separation; all of which facilitated an increase in real feature classification through manual image analysis. Drawbacks to the method included decreased image sharpness due to minor misalignment of images or moving vegetation, time required to create HDR images, and difficulty with acquiring primary images from a moving platform. We conclude that HDR imagery can provide more accurate measurements of bare soil cover for ecosystem monitoring and assessment.

These particular functional groups were chosen because they can participate in a copper-catalyzed reaction that combines them to form a 1,4-triazole, known as a 'click' reaction, which has been widely used in a variety of fields but remains underutilized in FA chemistry. Depending on the starting hydroxy FA, these groups can be close to the carboxy unit (using 3-hydroxydecanoate) and hence the polar glycerol group, or distant from it (using 17-hydroxyoctadecanoate). These structural alternatives will impart different properties to the triacylglycerols that are subsequently prepared from the modified FA.

Although reclamation is required by law, US General Accounting Office reports from 1999 and 2005 are clear that affected government agencies have-over much of the past decade-had difficulty accomplishing mandated environmental monitoring of extraction-related disturbance. We evaluated two pipeline rights of way (ROW) using nested images (1- or 2- with 13- or 20-mm ground sample distance (GSD)) acquired during Very-Large Scale Aerial (VLSA) surveys. Aerial monitoring allowed for the collection of large numbers of geocoded samples, and for subsequent cover measurements using methods with demonstrated accuracy equal to that of conventional ground-based methods. Both pipelines had vegetative-cover deficiencies relative to their Plan of Development (POD) requirements. Using bare ground and ground-cover measurements from the higher-resolution imagery, we present a spatial representation of each pipeline ROW that allows quick identification of sections of the ROW that may need further reclamation action to meet POD standards. We also present aerial monitoring costs. We recommend VLSA pipeline surveys as a means for facilitating required environmental monitoring and for addressing the monitoring backlog that has developed with increased energy-extraction activity.

Both byproducts have been studied separately for land application benefits. There are possible environmental benefits of WTRs and biosolids co-application but these studies are limited. Our objectives were to determine relative long-term (13-15 yr) effects of a single and short-term (2-4 yr) effects of repeated WTR-biosolids co- applications on soil chemistry, microbiology, and plant community structure in a Colorado semiarid grassland. Only relative changes associated between co-applications were studied, as we assumed WTR application would only occur if used as a management practice. Three WTR rates (5, 10, and 21 Mg ha super(-1)) were surface co-applied (no incorporation) with a single biosolids rate (10 Mg ha super(-1)) once in 1991 (long-term plots) and again in 2002 (short-term plots). Soil 0- to 8-, 8- to 15-, and 15- to 30-cm depth pH, electrical conductivity (EC), NO sub(3)-N, NH sub(4)-N, total C, and total N were not affected by WTR application in 2004, 2005, or 2006. Ammonium-bicarbonate diethylenetriaminepentaacetic acid (AB-DTPA)- extractable soil Al was unaffected by WTR application, but extractable P and Mo decreased with increasing WTR rate because of WTR adsorption. Plant tissue P and Mo content decreased with specific plant species and years due to adsorption to WTR; no deficiency symptoms were observed. Plant community composition and cover were largely unaffected by WTR application. Soil microbial community structure was unaffected by WTR co-application rate (total ester-linked fatty acid methyl ester [EL-FAME] concentrations ranged from 33.4 to 54.8 nmol g super(-1) soil), although time since biosolids-WTR application affected a subset of microbial community fatty acids including markers for Gram-positive and Gram-negative bacteria. Overall, WTR-biosolids co-applications did not adversely affect semiarid grassland ecosystem dynamics.

Shake-flask experiments revealed polymer productivities (the percent of the cell mass that is polymer) of 31c1% (n=3) and 23c3% (n=3) when grown in 13-MTDA and IA, respectively. Monomer content was determined by a combination of gas chromatography/mass spectrometry (GC/MS) of the acid hydrolyzed, silylated methyl esters, and nuclear magnetic resonance spectroscopy. Results showed that the mcl-PHA polymer derived from 13-MTDA was primarily composed of 3-hydroxy-7-methyloctanoic acid and 3-hydroxy-9-methyldecanoic acid (67 and 16mol% by GC/MS, respectively). In contrast, the mcl-polymers synthesized from the IA isomeric mixture were more complex, containing both even and odd chain-length monomers as well as varying distributions of methyl-branched derivatives. The PHA distributions among the C8, C10, C12, and C14 carbon chain-length monomers included three isomers of C8, five isomers of C10, seven isomers of C12, and nine isomers of C14 each containing one linear-chain derivative and n-6 methyl-branched derivatives where n equals the total number of carbon atoms in each monomer unit (C8-C14).

Nevski ssp. asperum (Simonk.) Melderis] have decreased livestock productivity and biological diversity and increased the frequency of wildfire on rangelands in the western United States. On disturbed sites, squirreltail (Elymus sp.), a short-lived North American perennial, appears to compete against invasive exotic annuals when available soil N and nitrification are reduced. We tested the hypothesis that differences in N uptake activity could account for this phenomenon. North American seedlings of perennial bluebunch wheatgrass [Pseudoroegneria spicata (Pursh) A. Loeve], four populations of squirreltail, and two invasive exotic annuals were cultured in the laboratory on NH sub(4) super(+), NO sub(3) super(-), or NH sub(4)NO sub(3) nutrient solutions, and N uptake activity (mol kg super(-1) root dry wt. h super(-1)) was measured. The overall biomass means of 4-wk-old seedlings cultured with NO sub(3) super(-), NH sub(4)NO sub(3), and NH sub(4) super(+) were 72, 67, and 42 mg seedling super(-1), respectively. Regardless of N form, cheatgrass biomass was as much as 4.2- fold greater than any of the other grasses including medusahead, which exceeded the biomass of all perennials except one. Cheatgrass had 1.5- to 2.2-fold greater NO sub(3) super(-) uptake activity than the perennials, but the NO sub(3) super(-) uptake activity of medusahead exceeded only two of the squirreltail populations. Ammonium uptake activities of perennials were not consistently more favorable than those of the annuals. The vigorous seedling growth of the invasive annuals coupled with the greater NO sub(3) super(-) uptake activity of cheatgrass appear to be primary traits of the invasive annuals, driving their superior N capture and competition compared with these North American perennial grasses.

Since that time, two additional species of Komagataella have been described, K. pseudopastoris and K. phaffii. Because these three species are unlikely to be resolved from the standard fermentation and growth tests used in yeast taxonomy, the identity of biotechnologically important strains of K. pastoris was determined from multigene sequence analyses. Results from this study show that the strain of 'Pichia pastoris' commonly used in gene expression studies is actually K. phaffii.

Infection was observed in a diversity of accessions that included Capsicum annuum, C. baccatum, C. chinense, and C. frutescens. The C. annuum accessions included culinary bell pepper cultivars and breeding lines as well as a diverse collection of ornamental breeding lines, heirlooms, and land races. Significant leaf damage occurred and led to partial defoliation. Extensive coverage of the abaxial surface by white patches of conidia was noted, along with chlorotic regions on the adaxial surface. Conidia were borne singly and were apically tapered, measuring 65.2 + 3.2 x 14.9 c 1.9 km. Cleistothecia were not found on infected leaves. PCR amplification of the internal transcribed spacer (ITS) region using ITS1-2 primers yielded a band that was cloned and sequenced. The pathogen was identified as Leveillula taurica based on 100% homology to GenBank Accession No. AY912077. Multiple chili pepper and bell pepper plants were inoculated with conidia from an infected bell pepper plant by placement in an enclosed spore deposition chamber for 1 week, with the infected plant suspended over the test plants. Signs of powdery mildew appeared only on inoculated plants. DNA samples from these inoculated plants were analyzed and verified as L. taurica (a sequence was deposited as GenBank No. GQ167201). A second set of inoculations using the newly infected plants confirmed results of the first test, with mildew developing only on inoculated pepper plants. This disease is new to the mid-Atlantic Region of the United States. It has been reported in greenhouse peppers growing in Ontario, Canada where it has become a recurring problem requiring fungicide intervention. Given the wide host range of L. taurica and the systemic nature of infections, it is likely that the fungus has become established in Maryland on perennial host plants.

Nucleotide sequence analysis of genomic RNA of the Korean SYMMV isolate suggested that the virus is a new member of the genus Carmovirus in the family Tombusviridae. To determine whether SYMMV is present in the United States, single leaflets were collected without regard for symptoms from 7 to 10 plants in each of 136 plots in August 2008 from a research field in Stoneville, MS that contained 16 plant introductions (including five from Korea) and 'Williams 82'. Samples were grouped into 10 pools of 100 leaves from which total RNA was extracted with the Qiagen RNeasy Plant Mini Kit (Germantown, MD), reverse transcribed, and amplified with Superscript III Platinum SYBR Green One-Step Quantitative Real-time Reverse Transcriptase-PCR Kit (Invitrogen, Carlsbad, CA) and two pairs of oligonucleotide primers (5'-CGTCTGCC AGGGTTTAATACTA-3', and 5'-GATTAGCATGTCAGGGTGGTCG-3'; and 5'-ACTGAGTCCCCTGCTTAT-3' and 5'-CATCACTAGCGTCYGG ATCA-3') that were designed from regions conserved between SYMMV and Cowpea mottle virus (CPMoV; a related and seed-transmitted carmovirus). Six 100-leaflet pools were positive with both primer sets and four pools were negative with both primer sets. Total RNA extracted from one positive pool was reverse transcribed using Superscript II reverse transcriptase and a primer complementary to nt 4,000 to 4,009 of the SYMMV genome and amplified using iProof DNA polymerase (Bio-Rad, Hercules, CA) as two overlapping DNA fragments using primers corresponding to nt 1 to 21 and complementary to nt 3,483 to 3,508 and corresponding to nt 3,366 to 3,391 and complementary to nt 4,000 to 4,009. DNA fragments were sequenced using a BigDye Terminator Cycle Sequencing Kit and ABI 3730XL capillary sequencers (Applied Biosystems, Foster City, CA). The 4,009-nt sequence of the Mississippi SYMMV isolate (GenBank Accession No. FJ707484) was 96% identical to the Korean SYMMV isolate and 65% identical to CPMoV. Because of the sampling techniques used, it was not possible to associate SYMMV-positive plants with disease symptoms in Mississippi. To our knowledge, this is the first report of SYMMV in North America.

National, state, and local policies and procedures that can mitigate these problems are needed. Market-based approaches where waste treatment plants (point sources) can purchase nutrient credits from upstream agricultural operations (non-point sources) to meet their National Pollutant Discharge Elimination System permit requirements within the Clean Water Act are being explored. This paper reviews these market-based approaches for enhancing air and water quality at a lower cost than simple command-and-control regulation, and describes new tools that are being developed, such as Nitrogen Trading Tool (NTT), that can be used to assess nitrogen losses to the environment under different management scenarios. The USDA-NRCS, EPA and several other state and local agencies are interested in these new tools. The NTT, though primarily designed for water quality markets, also estimates savings in nitrous oxide (N sub(2)O) emissions that can be traded in carbon markets. For example, an analysis using NTT shows that for 100ha of crop land, a C sequestration equivalent of approximately 25-38MgCy super(-) super(1) for a farm in Ohio, and 13-21MgCy super(-) super(1) for a farm in Virginia could be achieved with better nitrogen management practices. These numbers across a watershed could be much larger with improved N and conservation management practices that contribute to better water quality and lower global warming potential. There is a need to further develop, calibrate, and validate these tools to facilitate nitrogen and carbon trading future markets around the globe to increase environmental conservation across agro-ecosystems worldwide.

Forty-six potato selections were tested in three field trials from 2006 to 2008. Resistance was determined by comparing disease severity on aboveground stems to the mean disease severity of the industry standards Russet Burbank, Ranger Russet, and Umatilla Russet. The potato selections were also tested for geno-type*environment interaction to determine their genetic stability. Heritability of resistance was calculated to be 0.13 with confidence intervals between 0.00 and 0.68. The selections A0012-5, PA95B2-4, PA98NM38-1, and PO94A009-7 had less black dot than the standards in all years, and also demonstrated genetic stability. These selections also possess resistance to the root galling stage of the powdery scab pathogen Spongospora subterranea f. sp. subterranea. PA95B2-4, PA98NM38-1, and PO94009-7 were derived from an introgression program to incorporate resistance to the Columbia root-knot nematode Meloidogyne chitwoodi from the Mexican wild species Solarium bulbocastanum, and also have the commercial cultivar Summit Russet in their ancestry. These selections are promising steps toward sustainable management of black dot and powdery scab and will be further tested and used for breeding purposes.

False smut is an emerging disease worldwide that is rapidly gaining in importance, whereas kernel smut has historically been a chronic minor disease with sporadic outbreaks that cause considerable losses. Highly effective disease control was obtained for susceptible cultivars by employing conservation tillage (69% reduction in false smut), continuous rice cropping (88% reduction in false smut), and moderate nitrogen fertility rates (34 and 60% reductions in false smut and kernel smut, respectively). Combining these treatments nearly eliminated smuts from cultivars that were fully susceptible under conventional cultivation practices. Furthermore, using a nursery designed to promote smut diseases, two rice hybrids were identified that possessed kernel smut resistance under the most favorable disease conditions. The genetic basis of the resistance is unknown. However, the utility for disease control is great because hybrids occupy significant portions of production rice acreage.

Methods:We used data from 1600 Chinese, 11756 Indonesian and 53826 Vietnamese children aged 2-18 years, who participated in three recent, representative surveys in China, Indonesia and Vietnam. A smaller difference between prevalence and a higher Kappa -statistic indicated a higher consistency level. Results:The prevalence of underweight was higher with the IOTF than the CDC cut points; absolute differences in the Chinese, Indonesian and Vietnamese were 6, 10 and 13% (boys), and 10, 13 and 19% (girls), respectively. The prevalence of overweight was more consistent (absolute differences were <2%, except for the 2-5.9-year-old Chinese and Indonesian children (from 2 to <5%)). Values of Kappa -statistic (from 0.55 to 0.88) varied by age, sex and ethnicity. The consistency was gradually improving from the Vietnamese to Indonesians and to Chinese boys and girls, from girls to boys, from the younger to older boys and from the older to younger girls. Conclusions:The age, sex and ethnic differences in the prevalence of underweight and overweight suggest a systematic evaluation of the cut points.

To assess the potential of alternative crops as sources of bioethanol production, we grew sweet potato (Ipomoea batatas) and cassava (Manihot esculentum) at locations near Auburn, Alabama and Beltsville, Maryland in order to measure root carbohydrate (starch, sucrose, glucose) and root biomass. Averaged for both locations, sweet potato yielded the highest concentration of root carbohydrate (ca 80%), primarily in the form of starch (ca 50%) and sucrose (ca 30%); whereas cassava had root carbohydrate concentrations of (ca 55%), almost entirely as starch. For sweet potato, overall carbohydrate production was 9.4 and 12.7 Mg ha super(-1) for the Alabama and Maryland sites, respectively. For cassava, carbohydrate production in Maryland was poor, yielding only 2.9 Mg ha super(-1). However, in Alabama, carbohydrate production from cassava averaged [not, vert, similar]10 Mg ha super(-1). Relative to carbohydrate production from corn in each location, sweet potato and cassava yielded approximately 1.5x and 1.6x as much carbohydrate as corn in Alabama; 2.3x and 0.5x for the Maryland site. If economical harvesting and processing techniques could be developed, these data suggest that sweet potato in Maryland, and sweet potato and cassava in Alabama, have greater potential as ethanol sources than existing corn systems, and as such, could be used to replace or offset corn as a source of biofuels.

E.O. Speer f. sp. tritici. The gene was first confirmed in the wheat-rye translocation cultivar Amigo. In Amigo, the translocation is T1AL-1RS and the IRS arm has the gene Pm17. In the mid-Atlantic United States, at least two widely deployed soft red winter wheat (Triticum aestivum L.) cultivars, McCormick and Tribute, possess Pm17 inherited from Amigo. Before 2009, low frequencies of mostly intermediate virulence to Pm17 were detected among isolates from research plots of highly susceptible cultivars, but Pm17-bearing cultivars remained immune to mildew in the field. In April 2009, moderately severe powdery mildew was observed for the first time throughout plots of McCormick, Tribute, and other cultivars in both Kinston and Raleigh, NC. At Kinston, Pm17 virulence was observed at two research sites, separated by approximately 10 km, throughout plots of Amigo, McCormick, Tribute, and the hard red winter wheat cultivar TAM 303, which also contains Pm17. In the same month, virulence to Pm17 was observed in Raleigh throughout rows and plots of Amigo and TAM 303. In Kinston and Raleigh, ratings of powdery mildew severity on the Pm17-containing cultivars were 4 or 5 on a scale of 0 to 9, with 0 being the absence of mildew pustules and 9 the most severe mildew infection. Mildew was observed on leaves of all ages. Mildewed leaves were collected from field plots of all four Pm17-bearing cultivars, and an assay to confirm Pm17 virulence was conducted in the laboratory. Mixed-isolate cultures were derived from the leaves and a detached-leaf assay was performed using Amigo, which is the standard Pm17 differential. All tested cultures were fully to moderately virulent on Pm17 and all were fully virulent on the susceptible control Chancellor. In the field, chasmothecia (sexual fruiting bodies) were observed on Pm17-bearing cultivars. Together with the quantitatively varying Pm17 virulence detected in the laboratory assay, this suggests that multiple strains of Pm17 - virulent B. graminis f. sp. tritici may be present in the field, although that has not yet been demonstrated. Pm17 has protected wheat from powdery mildew over a substantial area in the mid-Atlantic United States. The loss of Pm17 is the most important virulence shift in the U.S. wheat powdery mildew population since Pm4a became ineffective around 2002. Isolates virulent to Pm17 can be expected to appear and multiply in wheat-producing states of the mid-Atlantic United States, including Delaware, Maryland, Virginia, North Carolina, South Carolina, and Georgia. Thus, the urgency of developing and releasing wheat cultivars with other sources of effective mildew resistance is heightened.

A portion of the flowpath of calcium within forests includes translocation as Ca super(2+) in sapwood and accumulation as crystals of calcium oxalate in foliage. Concentrations of Ca in these tree tissues have been used as markers of environmental change due to acidic deposition or forest management practices. We compared the effects of Ca fertilization treatment on Ca concentration in wood and Ca and oxalate (Ox) concentration in foliage at two locations with different initial concentrations of Ca in the soil. We found greater amounts of Ca in wood from the high-Ca location than from the low-Ca location. Ca concentration was greater in wood formed in the 1970s than for wood formed in the 1980s, the outermost decadal band in these samples. The Ca-treatment was detected as an increased concentration of Ca in the 1970s and 1980s decadal bands. We also found that variation in Ca and Ox in foliage was essentially stoichiometric. The appearance and response to chemical tests of crystals in foliage were consistent with identification as calcium oxalate. The increased Ca in wood after Ca-treatment of the soil supports the use of dendrochemistry of base cations to investigate environmental change. However, differences in Ca concentration between the two outermost decadal bands of wood illustrate that internal processes of translocation and storage also affect Ca concentration. Calcium oxalate production in foliage diverts carbon from ordinary biosynthesis and energy-yielding processes. This sequestration, shedding, and decomposition of foliage may represent a significant and under-recognized contribution to carbon and Ca cycling.

Lady beetles are attacked by a variety of natural enemies (bacteria, fungi, mites, nematodes, protozoa, wasps, flies). Few of these enemies have the ability to alter significantly the population dynamics of their hosts. This review should encourage further research to help define the role of natural enemies in the population dynamics of coccinellids. Ultimately, the conservation of beneficial lady beetles and the management of nuisance and pestiferous ones should be major emphases of research on coccinellid- natural enemy interactions.

Under field conditions, numerous coccinellids consume nectar, honeydew, pollen, fruit, vegetation, and fungus. These non-prey foods are used by coccinellids to increase survival when prey is scarce, reduce mortality during diapause, fuel migration, and enhance reproductive capacity. Each of these non-prey foods has unique nutritional and defensive characteristics that influence its suitability for lady beetles. Quantitatively, nutrient and energy contents of these foods are often competitive with, or even exceed that, present in prey. Meta-analyses of literature were used to assess whether (1) some non-prey foods and prey are equivalent foods for coccinellids, and (2) prey-only diets and mixed diets involving prey and non-prey foods are equally suitable for coccinellids. Response variables were categorized as larval performance (e.g., development time, weight at eclosion), adult performance (e.g., adult longevity, weight change), and reproduction (e.g., fecundity, oviposition period). The analyses revealed that pollen is inferior to prey for supporting larval and adult performance, but that adult performance in sugar-fed adults was equal to that of prey-fed adults (although sugar alone does not support reproduction). Larval performance was enhanced substantially when they were reared on mixed diets compared to prey-only diets. Adding sugar to mixed diets strongly improved adult performance and reproduction over prey-only diets, but this was not the case with pollen in mixed diets. These results suggest that coccinellid larvae have more stringent nutritional requirements than adults, and that non-prey foods provide unique nutrients that enhance prey- only diets. Moreover, it suggests that simple carbohydrates are important dietary constituents capable of enhancing both adult performance and reproduction, although it is important to note that a range of prey species of variable quality for coccinellids are evaluated in this database. The literature review presented here suggests that non-prey foods are a critical component of coccinellid nutritional ecology, and may influence the success of conservation biological control programs.

Experiments were conducted on seedlings of an indicator plant, the Brazilian morningglory (Ipomoea setosa Ker Gawl.), and sweet potato [Ipomoea batatas (L.) Lam.] to assess acquisition, retention and transmission of SPLCV by B. tabaci. Assays were based on the ability of the adult whitefly to acquire and transmit the virus. Two independent techniques, based on the expression of symptoms on the indicator plants and the detection of SPLCV with real-time polymerase chain reaction, were used to indicate SPLCV infection. The acquisition time of SPLCV by adult B. tabaci was 24 h and reached 100% by 84 h of exposure. Retention of SPLCV infectivity by viruliferous adults reached up to 30 days on non-SPLCV host plants (collard, Brassica oleracea ssp. acephala de Condolle). In transmission tests, a minimum of 15 min was required for a viruliferous whitefly population to transmit the virus to I. setosa. The efficiency of transmission increased over time; however, only 60% of the assay plants were infected after exposure to viruliferous whiteflies for 48 h. Male and female adult whiteflies vectored SPLCV with similar efficiency. Findings from this study will help to understand the epidemiology of SPLCV in sweet potato fields, and ultimately in the management of this disease. Such detailed investigations to assess vector behaviors also have implications in the study of other whitefly- virus systems among agricultural crops.

This review examines adult distribution and female oviposition strategies which in turn determine the distribution of coccinellid larvae in habitats. Immigration into a habitat can be influenced by visual and olfactory cues related to habitat quality. Adults are retained in a habitat if sufficient food resources are present. The abundance and quality of food in a habitat affects the reproductive output of a female and survival of larvae. Consequently, there is higher retention and oviposition preference for sites with abundant essential prey. Coccinellids also increase reproduction in response to non-prey foods (i.e., pollen), but avoid ovipositing in areas with copious amounts of honeydew. In laboratory studies, many plant- derived chemicals have been demonstrated to be attractants and oviposition stimulants. The need to place eggs in proximity to food for offspring must be weighed against the risk of cannibalism and intraguild predation. Lady beetles avoid egg predation by reducing oviposition where other adults are present, ovipositing on plants associated with less exposure or incidence of intraguild predation, and avoiding areas with tracks and frass of con- and heterospecific larvae. Indeed, deterrent cues for avoiding predation seem stronger than the positive ones associated with food. An understanding of the resources needed for successful reproduction and larval development in a habitat and the sensory cues that signal these resources, and thus elicit oviposition, may enhance our understanding of the underlying mechanisms affecting coccinellid distribution in habitats.

The commercial bacterial identification system, Biolog Microlog+, confirmed the identity of L. garvieae. Infectivity trials conducted in Nile tilapia using Brazilian Nile tilapia L. garvieae isolates resulted in a median lethal dose-50 of 1.4 x 105 colony-forming units (CFU)-fish. This is the first evidence of the presence of this pathogen from Brazilian fish. In addition, this is the first report of L. garvieae infection in either Nile tilapia or pintado. Collectively, this evidence expands the geographical range of fish hosts, number of fish hosts harbouring L. garvieae and carbon source utilization by L. garvieae fish isolates. Furthermore, the Biolog system may be an alternative technique to polymerase chain reaction for the identification of L. garvieae and discrimination between closely related bacterial species.

Darbysh.] productivity and persistence often benefits from association with Neotyphodium coenophialum [Morgan-Jones and Gams], Glenn, Bacon, and Hanlin) endophyte. The influence of novel, non-ergogenic endophytes on nutritive value is unclear, especially when simultaneous stresses (e.g., defoliation and shading) are imposed on the association. We conducted a field experiment using Jesup tall fescue that had either a native or novel non-ergogenic fungal endophyte (AR542; referred to as MaxQ[TM]), or that was endophyte free. Dry matter production and nutritive value including crude protein (CP), non-structural carbohydrates (TNC), ergo- and loline alkaloids, and phenolics were determined for plants stockpiled or clipped repeatedly in sites differing in the amount of light. Productivity varied less among sites when plants were infected with a native endophyte compared to novel or no endophyte. The trend suggests that native endophyte contributed to resilience of the host in this experiment. Leaf dry matter content was affected by host-endophyte association interacting with light availability suggesting differences in leaf composition could occur. Herbage CP increased, whereas TNC decreased with increasing shade. The concentration of loline alkaloids, irrespective of host-endophyte association, tended to increase in leaves with decreasing light availability and could be related to the relatively greater N concentrations in shade-grown leaves. Phenolics decreased in leaves, but increased in stembases as light availability decreased. The combination of increased loline alkaloids in leaves and phenolics in stembases, suggests that shade-grown tall fescue might have some competitive advantage based on the known anti-herbivory attributes of loline alkaloids and phenolic compounds.

Four different treatments were used: Control (C), Cadmium (Cd), Silicon (Si) and Cadmium plus Silicon (Cd + Si). The Si concentration was 35 mM. Thirteen-day-old plants were harvested. Growth parameters (length of primary seminal root, leaf area of first and second fully developed leaves, fresh and dry weight of below- and above-ground parts of the plants), and Cd concentration and total amount of Cd in the below- and above-ground parts were determined. In roots, the development of the endodermal barrier was observed by fluorescent staining with Fluorol yellow 088. Inhibitory effects of Cd on plant growth were observed. Silicon treatment in the absence of Cd had positive effects on most of observed growth parameters compared with the control. Moreover, Si in the Cd + Si treatment improved all growth parameters compared with the cadmium treatment. Silicon increased the cell-wall extensibility both in Si and Cd + Si treatments when compared with the control. Alleviation of the Cd-inhibitory effect on maize plants by Si was not due to exclusion of Cd from the plant; in contrast, Cd concentration in below- and above- ground plant parts and the total amount of Cd per plant were significantly higher in the Cd + Si plants than in the Cd treatment. The increased Cd content in Cd + Si plants was correlated with the development of the endodermis; during the second stage of endodermal development, suberin lamellae were formed at a greater distance from the root apex in the Cd + Si than in the Cd treatment. Silicon itself did not influence the development of suberin lamellae in the maize roots compared with the control.

Dietary breadth and its implications remain largely unexplored. Likewise the nature and implications of interactions with other predators in the field are poorly understood. The use of biochemical tools based on nucleic acids, proteins, sugars and other components of coccinellid diets, expands our understanding of their trophic ecology - but only under field conditions in which coccinellids live, reproduce, forage, and consume prey (including intraguild prey), pollen, fungi, nectars, and other foods. We review the various methods which have been applied to the study of trophic relationships involving the Coccinellidae, their advantages and disadvantages, and some salient innovations and results produced by the range of technologies and their combinations. We advocate employing multiple tools to generate a more complete picture of the trophic ecology of a predator. The false perceptions of the strength and direction of trophic linkages that can result from a methodologically narrow approach are well illustrated by the laboratory and field assessments of coccinellids as intraguild predators, a phenomenon that is discussed in detail here. Assessing intraguild predation, and the breadth of prey and non-prey foods of the Coccinellidae, is essential to the understanding of this group, and for their application as biological control agents.

However, their in situ impact and spatial variation are largely unknown. We examined spatial patterns of pathogenic activity in a deciduous forest using a common garden experiment and also in a natural experiment around replicated trees, and we quantified Pythium (a soil-borne pathogen) density around individual Prunus serotina trees. In both experiments, P. serotina seedling survival was 52-57% greater in plots treated with a metalaxyl-based fungicide specific to oomycetes (i.e., Pythium) than in untreated plots. Disease dynamics were not density dependent, but pathogenic activity and Pythium density were spatially variable. In the common garden and natural experiments, pathogenic activity of soil inoculum varied among trees, while in the natural experiment disease dynamics were also distance dependent and pathogenic activity decreased away from P. serotina trees. Disease and Pythium density were not always related but displayed considerable spatial variation. We found that Pythium density did not vary with distance away from P. serotina trees but did vary among trees. Understanding the spatial complexity of soil-borne pathogens is critical to accurately characterizing their effects on populations and ultimately on forest diversity.

Effective population sizes in Montana, Idaho, and Wyoming, where most of the wolverines in the contiguous United States exist, were calculated to be 35 (credible limits, 28-52) suggesting low abundance. Landscape features that influence wolverine population substructure and gene flow are largely unknown. Recent work has identified strong associations between areas with persistent spring snow and wolverine presence and range. We tested whether a dispersal model in which wolverines prefer to disperse through areas characterized by persistent spring snow cover produced least-cost paths among all individuals that correlated with genetic distance among individuals. Models simulating large preferences for dispersing within areas characterized by persistent spring snow explained the data better than a model based on Euclidean distance. Partial Mantel tests separating Euclidean distance from spring snow-cover-based effects indicated that Euclidean distance was not significant in describing patterns of genetic distance. Because these models indicated that successful dispersal paths followed areas characterized by spring snow cover, we used these understandings to derive empirically based least-cost corridor maps in the U.S. Rocky Mountains. These corridor maps largely explain previously published population subdivision patterns based on mitochondrial DNA and indicate that natural colonization of the southern Rocky Mountains by wolverines will be difficult but not impossible.

Quantitative trait loci (QTLs) controlling rhizome proliferation were previously detected on homoeologous regions of LG3a and LG3b in two full-sib families derived from allotetraploid hybrids. Triticeae homoeologous group 3 aligns to rice chromosome 1, which contains the rice lax panicle and maize barrenstalk1 orthogene responsible for induction of axillary branch meristems, but this gene has not been mapped or sequenced in Triticeae. We developed bacterial artificial chromosome (BAC) libraries representing 6.1 haploid equivalents of the tetraploid Leymus genome (10.7 Mb). Overgo probes designed from the lax-barrenstalk1 orthogene hybridized to 12 Leymus BAC clones. Deduced amino-acid sequences from seven BAC clones were highly conserved with the rice, maize, and sorghum lax-barrenstalk1orthogenes. Gene specific primers designed from two of the most divergent BAC clones map to homoeologous regions of Leymus LG3a and LG3b and align with the lax-barrenstalk1 orthogene on rice 1L. Comparisons of genomic DNA sequences revealed two other conserved regions surrounding the Leymus LG3a, rice, and sorghum lax- barrenstalk1 ortholoci, and one of these regions was also present in maize and Leymus LG3b sequences. Comparisons of Leymus LG3a and LG3b lax-barrenstalk1 coding sequences and flanking genomic regions elucidate molecular differences between subgenomes.

Even though these organisms have been studied for more than 100 y, their effective use in the field remains elusive. Recently, however, it has been discovered that many of these entomopathogenic fungi play additional roles in nature. They are endophytes, antagonists of plant pathogens, associates with the rhizosphere, and possibly even plant growth promoting agents. These findings indicate that the ecological role of these fungi in the environment is not fully understood and limits our ability to employ them successfully for pest management. In this paper, we review the recently discovered roles played by many entomopathogenic fungi and propose new research strategies focused on alternate uses for these fungi. It seems likely that these agents can be used in multiple roles in protecting plants from pests and diseases and at the same time promoting plant growth.

Vegetation within powerline corridors is managed to prevent contact of vegetation with transmission lines, and comprises approximately 2% of all of habitat for scrub-shrub birds in southern New England. Although previous studies have documented the use of powerline corridors by scrub-shrub birds, important questions remain about the factors affecting the quality of corridors as habitat for these species. We surveyed birds and monitored nests on 15 corridors in western Massachusetts during 2002 and 2003 to determine whether scrub-shrub birds occupy and successfully reproduce in powerline corridors, and to identify the principal factors affecting scrub-shrub abundance and nesting success. We found that corridors were occupied by scrub-shrub birds of high regional conservation priority, however, four of seven focal scrub-shrub bird species were scarce or absent in narrow corridors, and the abundance of these species was highest in corridors of intermediate width. Overall, nest survival was low (0.14) at these sites relative to other types of early successional habitats in the region, however, if we consider only our sites that were wider than the median width (>=49m), nest survival in corridors was (0.33), similar to survival rates reported in other studies of scrub-shrub birds. We conclude that powerline corridors provide habitat for early successional birds of conservation concern, with wider corridors (>=50m) contributing more to regional conservation of these species.

However, only about 10% of the plant material is used for latex production; the remaining biomass, called bagasse, can be used for renewable fuel production. Fast pyrolysis of guayule, both whole shrub and bagasse was performed. From both feedstocks a very viscous, high energy content ([not, vert, similar]30 MJ/kg) pyrolysis liquid (bio-oil) was produced in yields averaging over 60% without any catalyst. The properties and compositions of the bio-oils were found to be similar in the two feedstocks. Co-products, charcoal (20-30 wt%) and non-condensable gas (5-15%), were also dense and had a high energy content. Of the two feedstocks, the whole shrub yielded higher quantities of charcoal that also had a higher energy content than the charcoal produced from bagasse. As a result, the energy recovery, estimated as the percentage of the energy products, to energy input into the reactor was lower (60%) for guayule bagasse than for the whole shrub (73%). This notwithstanding, the bagasse is a more attractive feedstock for thermochemical conversion, not only because it is a residue from a primary process (latex extraction) that is on-site, but also because it has a high energy content. Moreover, it produces high quality pyrolysis products. Co-production of latex rubber from the whole shrub and renewable fuels from the residual bagasse by pyrolysis should improve the already positive economics of the guayule latex rubber industry.

One proposal is to recycle drainage water to irrigate salt tolerant crops until the volume has been reduced sufficiently to enable final disposal by evaporation. Part of this concept requires in situ crop water reuse from shallow groundwater; and data is needed to quantify the potential use of groundwater by alternative crops. A column lysimeter study was initiated to determine the potential crop water use from shallow groundwater by alfalfa as a function of groundwater quality and depth to groundwater. The results demonstrated that up to 50% of the crop water use could be met from shallow groundwater (4dS/m) in the shallow groundwater experienced increased salinity in the soil profile with time, which resulted in reduced crop water use from shallow groundwater. Yields decreased with time as the groundwater salinity increased and periodic leaching will be required for in situ use to be a sustainable practice. Statistical analysis of crop yield demonstrated that there was significant use of groundwater with an EC of 6dS/m for a few years.

Treated fibers were incorporated in starch/ethylene vinyl alcohol copolymers (EVOH) blends. Mechanical and thermal properties of starch/EVOH/coir biocomposites were evaluated. Fiber morphology and the fiber/matrix interface were further characterized by scanning electron microscopy (SEM). All treatments produced surface modifications and improved the thermal stability of the fibers and consequently of the composites. The best results were obtained for mercerized fibers where the tensile strength was increased by about 53% as compared to the composites with untreated fibers, and about 33.3% as compared to the composites without fibers. The mercerization improved fiber-matrix adhesion, allowing an efficient stress transfer from the matrix to the fibers. The increased adhesion between fiber and matrix was also observed by SEM. Treatment with water also improved values of Young's modulus which were increased by about 75% as compared to the blends without the fibers. Thus, starch/EVOH blends reinforced with the treated fibers exhibited superior properties than neat starch/EVOH.

This process uses anaerobic bacteria, their own cellulolytic enzymes and fermentation pathways that convert the products of cellulose hydrolysis to ethanol in a single reactor. However, the engineering and economics of the process remain questionable. The ruminal fermentation is a very highly developed natural cellulose-degrading system. We propose that breakthroughs developed by cattle and other ruminant animals in cellulosic biomass conversion can guide future improvements in engineered CBP systems. These breakthroughs include, among others, an elegant and effective physical pretreatment; operation at high solids loading under non-aseptic conditions; minimal nutrient requirements beyond the plant biomass itself; efficient fermentation of nearly all plant components; efficient recovery of primary fermentation end-products; and production of useful co- products. Ruminal fermentation does not produce significant amounts of ethanol, but it produces volatile fatty acids and methane at a rapid rate. Because these alternative products have a high energy content, efforts should be made to recover these products and convert them to other organic compounds, particularly transportation fuels.

Pilot-scale pasteurizers are useful for product development, but comparisons on thermal inactivation kinetics with smaller scale systems are lacking. Using an Armfield pilot-scale pasteurizer and aluminum thermal-death-time (TDT) disks, the D-values and z- values of Escherichia coli K12 in apple cider were determined in the temperature range of 54-62 C. Come-up times to 58 C were also measured and were 35 and 61 s for the TDT disks and pasteurizer, respectively. The D-values from the TDT disks were 9.66, 4.01, 1.44 and 0.44 min at temperatures of 54, 56, 58, and 60 C, respectively. The D-values from the pasteurizer were 3.48, 1.22, 0.10 and 0.05 min at temperatures of 56, 58, 60, and 62 C, respectively. The z-values from the TDT disks and the pasteurizer were 4.68 and 3.60 C, respectively. There was no significant (P > 0.05) difference in the D-values of the TDT disks and pasteurizer at 56 and 58 C, while there was a significant (P < 0.05) difference in the D-value at 60 C and in the z-value. This study revealed that the thermal inactivation kinetics obtained using bench scale TDT disks and an Armfield pilot-scale pasteurizer under certain conditions are similar. However, based on ease of use and other factors, TDT disks are preferable for acquiring thermal inactivation kinetics.

The objective of this study was to develop a second-generation treatment system that can achieve high EST standards at reduced costs. The system used solids separation, nitrification/denitrification and phosphorus removal/disinfection, and was demonstrated at full-scale on a 5145-head swine farm during three production cycles (15-months). Removal efficiencies were: 98% suspended solids, 97% ammonia, 95% phosphorus, 99% copper and zinc, 99.9% odors, and 99.99% pathogens. The system met EST standards at 1/3 the cost of the previous version. Animal health and productivity were enhanced; hog sales increased 32,900 kg/cycle (5.6%). These results demonstrated that: (1) significant cost reductions were achieved by on-farm implementation and continued engineering improvements, and (2) the new waste management system substantially benefited livestock productivity.

Innovative mitigation strategies are needed to remediate this potential environmental contaminant. One potential solution is to divert pesticide-laden drainage or surface water through agricultural rice fields. With a hydroperiod, hydrosoil and hydrophyte (rice), these systems serve essentially as a type of constructed wetland. In both summer and fall experiments, diazinon-amended water was diverted through two rice ponds at the University of Mississippi Field Station. Likewise, a non-vegetated control pond was amended with diazinon-laden water. Water, sediment and plant samples were taken spatially and temporally to determine the distribution of diazinon within systems. RESULTS: Outflow diazinon concentrations decreased significantly (P < 0.05) from inflow in both vegetated ponds for both preharvest and post-harvest experiments. Although sorption to rice plants was minimal in the overall mass distribution of diazinon (1-3%), temporal data indicated that diazinon concentrations reached the outflow sediment of the non-vegetated control twice as fast as in either vegetated (rice) system. In both vegetated systems, sediment diazinon concentrations decreased (77 and 100%) from inflow to outflow, while a decrease of <2% was noted in the non-vegetated control. CONCLUSIONS: Diversion of pesticide-contaminated water through rice fields demonstrated potential as a low-cost, environmentally efficient mitigation practice. Studies on these systems are continuing to evaluate the optimal chemical retention time for rice field mitigation, as well as diazinon transfer to rice grain seeds that may be used as a food source.

AN - 734154516; 19878589 AB - The diploid woodland strawberry (Fragaria vesca) is an attractive system for functional genomics studies. Its small stature, fast regeneration time, efficient transformability and small genome size, together with substantial EST and genomic sequence resources make it an ideal reference plant for Fragaria and other herbaceous perennials. Most importantly, this species shares gene sequence similarity and genomic microcolinearity with other members of the Rosaceae family, including large-statured tree crops (such as apple, peach and cherry), and brambles and roses as well as with the cultivated octoploid strawberry, F. xananassa. F. vesca may be used to quickly address questions of gene function relevant to these valuable crop species. Although some F. vesca lines have been shown to be substantially homozygous, in our hands plants in purportedly homozygous populations exhibited a range of morphological and physiological variation, confounding phenotypic analyses. We also found the genotype of a named variety, thought to be well-characterized and even sold commercially, to be in question. An easy to grow, standardized, inbred diploid Fragaria line with documented genotype that is available to all members of the research community will facilitate comparison of results among laboratories and provide the research community with a necessary tool for functionally testing the large amount of sequence data that will soon be available for peach, apple, and strawberry. A highly inbred line, YW5AF7, of a diploid strawberry Fragaria vesca f. semperflorens line called "Yellow Wonder" (Y2) was developed and examined. Botanical descriptors were assessed for morphological characterization of this genotype. The plant line was found to be rapidly transformable using established techniques and media formulations. The development of the documented YW5AF7 line provides an important tool for Rosaceae functional genomic analyses. These day-neutral plants have a small genome, a seed to seed cycle of 3.0 - 3.5 months, and produce fruit in 7.5 cm pots in a growth chamber. YW5AF7 is runnerless and therefore easy to maintain in the greenhouse, forms abundant branch crowns for vegetative propagation, and produces highly aromatic yellow fruit throughout the year in the greenhouse. F. vesca can be transformed with Agrobacterium tumefaciens, making these plants suitable for insertional mutagenesis, RNAi and overexpression studies that can be compared against a stable baseline of phenotypic descriptors and can be readily genetically substantiated.

However, the growing dependency on civil aviation for global commerce can require increases in capacity at airports which affect land use, wildlife populations, and perspectives on aviation safety. Our objectives were to (1) review legislation that affects airports and surrounding communities relative to managing and reducing wildlife hazards to aviation; (2) identify information gaps and future research needs relative to regulated land uses on and near airports, and the effects on wildlife populations; and (3) demonstrate how information regarding wildlife responses to land-use practices can be incorporated into wildlife-strike risk assessments. We show that guidelines for land-use practices on and near airports with regard to wildlife hazards to aviation can be vague, conflicting, and scientifically ill-supported. We discuss research needs with regard to management of stormwater runoff; wildlife use of agricultural crops and tillage regimens relative to revenue and safety; the role of an airport in the landscape matrix with regard to its effects on wildlife species richness and abundance; and spatial and temporal requirements of wildlife species that use airports, relative to implementing current and novel management techniques. We also encourage the development and maintenance of datasets that will allow realistic assessment of wildlife-strike risk relative to current airport conditions and anticipated changes to capacity. Land uses at airports influence wildlife populations, and understanding and incorporating these effects into planning will reduce risks posed to both aviation safety and wildlife species.

13812299 AB - We present a classification of duff, litter, fine woody debris, and logs that can be used to stratify a project area into sites with fuel loading that yield significantly different emissions and maximum soil surface temperature. Total particulate matter smaller than 2.5 km in diameter and maximum soil surface temperature were simulated using the First Order Fire Effects Model. Simulation results were clustered into 10 Effects Groups using an agglomerative routine where each Effects Group defined a unique range of soil temperature and emissions. Classification tree analysis was used to estimate the critical duff, litter, fine woody debris, and log loadings associated with the soil temperature and emissions of each Effects Group. The resulting 21 fuel classes are called Fuel Loading Models and classified the study dataset with an ~34% misclassification rate. The classification can be used to describe fuel loadings for a plot or stand, or as map units for mapping fuel loadings across large regions. The classification process can be used to develop finer-scale fuel classifications for specific regions or ecosystems.

AN - 734079615; 19686695 AB - Highly pathogenic (HP) H5N1 avian influenza has become endemic in several countries in Asia and Africa, and vaccination is being widely used as a control tool. However, there is a need for efficacious vaccines preferably utilizing a DIVA (differentiate infected from vaccinated animals) marker strategy to allow for improved surveillance of influenza in vaccinated poultry. Using a reverse genetics approach, we generated Asian rgH5N9 vaccine strain deriving the hemagglutinin gene from A/chicken/Indonesia/7/2003 (H5N1) with modification of the cleavage site to be low pathogenic (LP) and N9 neuraminidase gene from the North American LP A/turkey/Wisconsin/1968 (H5N9) virus. The recombinant rgH5N9, A/turkey/Wisconsin/1968 (H5N9) A/chicken/Hidalgo/232/1994 (H5N2), and wild type HP A/chicken/Indonesia/7/2003 (H5N1) viruses were used to prepare inactivated oil-emulsified whole virus vaccines. Two weeks after vaccination, chickens were challenged with either Asian HP H5N1 viruses, A/chicken/Indonesia/7/2003 (W.H.O. clade 2.1) or A/chicken/Supranburi Thailand/2/2004 (W.H.O. clade 1.0). The H5 HA1 of the North American vaccine strains exhibited 12% amino acid differences including amino acid changes in the major antigenic sites as compared to the Asian HP H5N1 challenge viruses, serologically exhibited substantial antigenic difference, but still provided 100% protection from mortality. However, challenge virus shedding was significantly higher in chickens immunized with antigenically distinct American lineage vaccines as compared to the antigenically matched Asian rgH5N9 and the wild type Asian H5N1 vaccine. The antibody response to the heterologous subtype neuraminidase proteins were discriminated in vaccinated and infected chickens using a rapid fluorescent 2'-(4-methylumbelliferyl)-alpha-d-N-acetylneuraminic acid sodium salt as substrate for neuraminidase inhibition assay. This study demonstrates the value of using a vaccine containing antigenically matched H5 hemagglutinin for control of HP H5N1 avian influenza in poultry and the potential utility of a heterologous neuraminidase as a DIVA marker.

14131886 AB - Black bears (Ursus americanus) forage selectively in natural environments. To determine if bears also forage selectively for anthropogenic resources we analyzed data on vehicles broken into by bears from Yosemite National Park, California. We classified vehicles into 9 categories based on their make and model and collected data on use (2001-2007) and availability (2004-2005). From 2001 to 2007 bears broke into 908 vehicles at the following rates: minivan (26.0%), sport-utility vehicle (22.5%), small car (17.1%), sedan (13.7%), truck (11.9%), van (4.2%), sports car (1.7%), coupe (1.7%), and station wagon (1.4%). Only use of minivans (29%) during 2004-2005 was significantly higher than expected (7%). We discuss several competing hypotheses about why bears selected minivans.

This large flood control reservoir serves as a sink for the Skuna and Yalobusha River watersheds whose highly erodible soils contribute to excessively high sediment yields and impaired water quality. This study was conducted to characterize the distribution of total Hg in watershed soils and determine the relationship between the easily transportable clay, organic C (OC), and Fe oxide fractions and the movement of Hg from upland sources to reservoir sinks. Cores were collected from soils, of different land-use, representative of the three soil orders (Alfisols, Entisols, and Vertisols) found in the watersheds. Sediment cores were collected from the Yalobusha River and Grenada Lake. In the laboratory, soil cores were sampled by horizon while sediment cores were sampled in 10 cm increments. These samples were characterized for total Hg, particle size distribution, OC, Fe oxide contents, and pH. Mercury concentrations ranged from 10 to 112 kg kg super(-) super(1) in the soil profiles, with average regression coefficient (r super(2)) values of 0.104, 0.362, and 0.06 for Hg versus clay, OC, and Fe oxides, respectively. River sediment cores had Hg concentrations ranging from 0 to 38 kg kg super(-) super(1), and significant (1% level) r super(2) values of 0.611, 0.447, and 0.632 versus clay, OC, and Fe oxides, respectively. Mercury concentrations in the lake sediment ranged from 0 to 125 kg kg super(-) super(1). The r super(2) values for Hg versus clay, OC, and Fe oxides in the lake sediment were 0.813, 0.499, and 0.805, respectively, all significant at the 1% level. These results indicate that total Hg is poorly correlated with the clay, OC, and Fe oxide fractions at depth in the soil profiles because maximum Hg concentrations occur in the surface horizons due to atmospheric in-fall. The statistically significant r super(2) values for Hg versus these components in the sediment cores are the result of particulate clay, Fe oxides, and finely divided OC sorption of Hg from solution during the runoff and sediment transport process. The higher correlations for the lake sediment reflect an enrichment of the Hg-laden clay fraction relative to stream sediment through flocculation and sedimentation processes in the slack-water environment of the reservoir.

11096464 AB - The BMI cut-score used to define overweight and obesity was derived primarily using data from Caucasian men and women. The present study evaluated the racial/ethnic bias of BMI to estimate the adiposity of young men and women (aged 17-35 years) using dual-energy X-ray absorptiometry (DXA) determination of percentage body fat (DXA-BF%) as the referent standard. The samples were 806 women and 509 men who were tested from one to three times over 9 months providing 1300 observations for women and 820 observations for men. Linear mixed models (LMM) regression showed that with age and BMI controlled, DXA-BF% of African-American (AA) men and women, Asian-Indian men and women, Hispanic women and Asian women significantly differed from non-Hispanic white (NHW) men and women. For the same BMI of NHW women, the DXA-BF% of AA women was 1.76% lower, but higher for Hispanic (1.65%), Asian (2.65%) and Asian-Indian (5.98%) women. For the same BMI of NHW men, DXA-BF% of AA men was 4.59% lower and 4.29% higher for Asian-Indian men. Using the recommended BMI cut-scores to define overweight and obesity systematically overestimated overweight and obesity prevalence for AA men and women, and underestimated prevalence for Asian-Indian men and women, Asian women and Hispanic women. The present study extends the generalisability of research documenting the racial/ethnic bias of the universal overweight and obesity BMI cut-scores.

Infected pig meat is a source of Toxoplasma gondii infection for humans and animals in many countries. This parasite also causes mortality in pigs, especially neonatal pigs. Most pigs acquire T. gondii infection postnatally by ingestion of oocysts from contaminated environment or ingestion of infected tissues of animals. Few pigs become infected prenatally by transplacental transmission of the parasite. Raising pigs indoors in confinement has greatly reduced T. gondii infection in pigs but the recent trend of organic farming is likely to increase T. gondii infection in pigs. Recently, feeding goat whey to pigs was found to be a risk factor for T. gondii infection in organically raised pigs. Currently used molecular and histopathological methods are insensitive for the detection of T. gondii in pork because of the low concentration of the parasite in meat destined for human consumption. There is no vaccine to prevent T. gondii infection in pigs but efforts are being continued to develop a non-viable vaccine. In the present paper, information on prevalence, transmission, diagnosis, and control of porcine toxoplasmosis in the last 20 years (since 1988 when last reviewed by this author) is reviewed. Worldwide reports of clinical and asymptomatic infections in pigs are reviewed. Methods to detect T. gondii in pigs are compared. Recent studies on genetic typing of T. gondii strains prevalent in pigs are discussed with respect to epidemiology. Because wild pigs are hunted for food for human consumption prevalence in wild pigs is summarized.

15309141 AB - Aluminum-based water treatment residuals (WTR) can adsorb water- and soil-borne P, As(V), As(III), and perchlorate, and may be able to adsorb excess environmental selenium. WTR, clay minerals, and amorphous aluminum hydroxide were shaken for 24 h in selenate or selenite solutions at pH values of 5-9, and then analyzed for selenium content. Selenate and selenite adsorption edges were unaffected across the pH range studied. Selenate adsorbed on to WTR, reference mineral phases, and amorphous aluminum hydroxide occurred as outer sphere complexes (relatively loosely bound), while selenite adsorption was identified as inner-sphere complexation (relatively tightly bound). Selenite sorption to WTR in an anoxic environment reduced Se(IV) to Se(0), and oxidation of Se(0) or Se(IV) appeared irreversible once sorbed to WTR. Al-based WTR could play a favorable role in sequestering excess Se in affected water sources.

To evaluate the distribution of amphiboles we used soil data from the USDA-NRCS Soil Survey Laboratory database. We analyzed the optical mineralogical data from selected sand fractions of pedons within the database. The sands encompass the range in particle size from 0.02 to 0.25 mm. Results show that soils in all states contain some amount of amphiboles, except for Rhode Island. The soil samples are from horizons within pedons, a 3-dimensional body of soils on the landscape that consists of one or more horizons with depth. Out of the 50 states, 40 had 10% or more of sampled pedons containing amphiboles. Overall, 4,396 pedons out of the 34, 326 pedons (about 13%) sampled in the United States contained some amount of amphiboles. State percentages of the number of pedons sampled containing amphiboles ranged from 0% to 49%. Excluding Rhode Island, Illinois had the lowest percentage (3%) of sampled pedons containing amphiboles. Arkansas had 49% of sampled pedons containing amphiboles. Sixteen percent or, 34,326 samples, which represent horizons within pedons, contained amphiboles out of an overall total of 212,389. Samples from each horizon varied in percentages from 1% (Florida) to 24% (Arkansas) excluding Rhode Island. Based on these data, amphibole content in United States' soils is somewhat evenly distributed across the country. Maps of asbestos mine locations published by USGS in the U.S. show few locations in the central U.S., while our data show an even distribution in this area. The USGS maps show trends of asbestos mines along mountain ranges (e.g., the Appalachians) whereas our percentage maps show no correlations with these deposits. One last important point deals with the morphology of the amphiboles. We assume that the vast majority of the amphiboles found in the soils would not meet the mineralogical definition of asbestos (i.e., they would not have been derived from asbestiform amphiboles), while the majority of them would meet the regulatory criteria (i.e., are over 5 microns in length with a greater that 3 to 1 aspect ratio). Following this later definition, then we would assume 13% of the pedons and 16% of the horizons are "naturally contaminated."

All climatological data have biases that may impact their applications outside of the original intent if not considered. Analysis shows SWE data is very useful for their intended purpose predicting current streamflow via hydrologic models by using the most recent SWE data (20 to 40 years), representing current watershed conditions. This research focuses on two issues which have had significant impact on data stability in Utah: vegetation and physical change at the manual sites and SWE sensor changes in the SNOTEL system. It was recognized very early on that snow accumulation at these sites would systematically change over time. "Forest cover is a significant factor in snow accumulation and melt at a snow course. Therefore, any change in forest cover may gradually affect the readings obtained over a period of years", NRCS National Engineering Handbook, Section 22, 1972. Snow course analysis in Utah shows dramatically altered conditions at some sites and little to no impact at others. Each site with vegetative or physical change regardless of elevation or latitude has decreased SWE (30 year average) whereas at sites with no vegetative change, SWE remains steady indicating that vegetation impacts, not climate change may be the source of the observed decreasing SWE. The SNOTEL system initially used stainless steel pillows as a SWE sensor. Later, hypalon pillows became the sensor of choice. Data comparison of dual steel/hypalon pillow sites shows that hypalon pillows begin SWE accumulation later, melt out earlier, and accumulate 8% to 25% less SWE than the steel pillows. Thus this data set has a systematic bias of declining SWE and early melt due to sensor change that could be confused for and/or mask a climate change signal if not properly analyzed. In making long term comparative analyses from the Snow Course data set, systematic bias should be quantified and removed from each individual site in order to give an accurate depiction of change due to climate. In the SNOTEL data set, sensor change bias should be quantified and removed.

Using both automated systems and manual data collection, the U.S. Department of Agriculture Natural Resources Conservation Service's Snow Survey and Water Supply Forecasting Program collects, processes, and distributes public data on snow, soil moisture content, and water supply. The basic data generated by the Snow Survey and Water Supply Forecasting Program provide essential information to entities, agencies, and organizations that depend on information about water for their core decisionmaking and operations processes. These basic data become even more valuable when used in concert with partner organizations to provide water supply forecasting tailored to meet end-user needs. Recently, a study was done to analyze who uses SS-WSF data, how the data are used, and the value of the data from an economic standpoint. This presentation will summarize and discuss the findings of this study.

Historically, the primary focus of snow survey data was to provide agricultural water supply forecasts. The Soil Conservation Service/Natural Resources Conservation Service (NRCS) has been the lead agency in the Cooperative Snow Survey since the early years. In the 1980's the installation of the SNOTEL network made the collection of daily and hourly data possible. The use of these data has grown tremendously by both the number of users and types of uses. As a result, the NRCS's role as a "coordinator and technical information provider" has grown as numerous users rely on quality, high elevation, NRCS data and water supply predictions to make decisions that are impacted by the variable snowfall and streamflow. The cooperative nature of measuring snow is still present in Idaho with 50 external cooperators and 25 internal snow surveyors making over 650 measurements a year. In recent years, due to turn-over and budget short-falls, the task of maintaining internal surveyors snow courses, as well as, meeting requests for new sites and products has become a challenge. It was suggested that a Snow Survey Advisory Team would be valuable to provide guidance and recommendations. The first meeting occurred in June with discussions about data sites, optimization of network, watershed assessment, snowmelt timing runoff products, meta-data, and collaboration of research and implementation of work. Meta-data have also been requested by other agencies and is needed by climatic change researchers. This talk will discuss the Snow Survey Advisory Team and opportunities to re-vitalize the cooperation nature of the program to better meet user's needs and utilize research capabilities at universities. Furthermore, it is hoped this collaboration will help stretch budgets to meet more requests and establish a cooperative effort for product development and distribution of information used at local, regional and national level.

Newly emerged spiderlings were reared on the eggs of Helicoverpa zea (Boddie) at four prey densities, 1, 5, 25, or 125 eggs, three times a week, with or without nectar. Nectar came from the extrafloral nectaries of Indian almond, Terminalia cattapa L. (Combretaceae). The addition of nectar to prey (1) allowed spiderlings on the 1-egg diet to survive longer and molt many more times; (2) allowed virtually all of the spiderlings on the 5-egg diet to become small adults and 50% to mate and reproduce versus those without nectar, none of which matured to adulthood; and (3) increased fecundity of females on 5-egg and 25-egg diets to the level of females fed five times the amount of prey. These results show that spiders that feed on nectar increase their fitness with increased survival, growth, and fecundity, particularly when density of prey is inadequate or marginal.

Here, we hypothesized that our established model could be used to determine if the SGSB was a general, non-discriminate vector by using two other opportunistic bacterial pathogens of bolls (Pantoea ananatis [Serano] and Klebsiella pneumoniae [Schroeter]) and the known fungal pathogen Nematospora coryli (Peglion). Variants of P. ananatis (strain Pa-1R) and K. pneumoniae (strain Kp 5-1R) selected for rifampicin (Rif) resistance were used as bacterial opportunists. N. coryli was detected only from laboratory-reared SGSB directly exposed to the fungus. Both Pa-1R and Kp 5-1R were recovered from SGSB previously provided a contaminated food source (2days), sterile food (5days), and then harvested after being caged on bolls (2days) at levels reaching 10 super(3) and 10 super(4) colony forming units (cfus) per insect, respectively. However, bolls caged with insects infected with Pa-1R or Kp 5-1R and with evidence of feeding did not become diseased nor were either opportunists detected from boll tissues. Insects infected with N. coryli transmitted the pathogen, which resulted in diseased bolls and fungi concentrations reached 10 super(6)cfus/g locule tissue at 2weeks following the caging period. Notably, each of the three pathogens independently caused boll disease when mechanically inoculated using a needle puncture. Generally, these results suggest that cotton pathogen acquisition by the SGSB was not sufficient to determine whether the insects were disease vectors of the opportunists.

Feline immunodeficiency virus (FIV) and feline leukemia virus (FeLv) are related to human immunodeficiency virus, and human leukemia virus, respectively; all of these viruses are immunosuppressive. In the present study, the prevalence of antibodies to T. gondi, Bartonella spp., FIV, as well as FeLv antigen were determined in sera from 75 domestic and 101 feral cats (Felis catus) from the Caribbean island of Grenada, West Indies. Using a modified agglutination test, antibodies to T. gondii were found in 23 (30.6%) of the 75 pet cats with titers of 1:25 in 1, 1:50 in 3, 1:400 in 4, 1:500 in 12, 1:800 in 2, and 1:1,600 in 1, and 28 (27.7%) of 101 feral cats with titers of 1:25 in 4, 1:50 in 7, 1:200 in 4, 1:400 in 1, 1:500 in 3, 1:800 in 2, 1:1,600 in 3, and 1:3,200 in 4. Overall, in both pet and feral cats, the seroprevalence increased with age. Antibodies to Bartonella spp. were found in 38 (50.6%) of the 75 pet cats and 52.4% of 101 feral cats. Antibodies to FIV were found in 6 domestic and 22 feral cats. None of the 176 cats was positive for FeLv antigen. There was no correlation among T. gondii, Bartonella spp., and FIV seropositivity.

RESULTS: Although nine phenolic compounds (gallic acid, catechol, catechin, epicatechin, m-coumaric acid, chlorogenic acid, ellagic acid, caffeic acid and an ellagic acid derivative) were identified in the methanol extract (80% methanol) of defatted kernels, only three compounds (gallic acid, catechin and ellagic acid) existed in sufficient amounts to accurately quantify levels in different cultivars and to study differences in organic versus conventional cultivation. Levels of ellagic acid and catechin found in organically grown Desirable were fourfold and twofold higher than in conventional samples, respectively. Furthermore, significant differences in these two compounds were also observed when comparing values between cultivars. Oil content was also significantly greater only in organically grown Desirable. Oleic acid was the major fatty acid present and its content was significantly higher in organically versus conventionally grown Desirable pecans, while there was no difference in levels of oleic acid in Wichita and Cheyenne. On the other hand, linoleic acid content was significantly less in organically versus conventionally grown Desirable pecans. CONCLUSION: Overall, these results showed that the effects of cultural differences (i.e. organic versus conventional cultivation) on kernel composition largely depend on the type of pecan cultivar.

Developing environmental water requirements for groundwater-dependent ecosystems AN - 753850796; 2010-069669 AB - Groundwater-dependent ecosystems (GDEs) include lakes, wetlands, and rivers that are found at points of groundwater discharge, as well as subterranean and aquifer ecosystems. They are strongly adapted to relatively stable groundwater supply. Similar to groundwater sources for human consumption, GDEs are threatened by groundwater depletion and contamination. Yet unlike municipal and agricultural groundwater supply systems, little is known about thresholds for groundwater quality and quantity below which a GDE is irreversibly altered. The objective of this project is to develop quantitative thresholds for groundwater discharge, termed environmental water requirements, for groundwater-dependent wetlands called fens. This pilot project is being conducted in 3 fens in the Fremont-Winema National Forest in Oregon. The study sites are located in the northern part of the arid Upper Klamath Basin, where groundwater plays an important role in stream baseflow and wetland hydrology. The fens are in a grazing allotment where water is withdrawn for cattle, thus understanding thresholds for groundwater discharge and withdrawal is critical to manage these ecosystems. We are using two approaches to set upper limits on water withdrawals. In a "top-down" approach, we are developing hydrologic models to test the sensitivity of water budget parameters to change and to evaluate their effect on groundwater availability. In a "bottom-up" approach, we are developing quantitative relationships between indicator plant species, peat properties, and the timing and depth of water table fluctuations. For the latter, bottom-up approach, we are monitoring depth to water table, piezometric head at several depths within the peat profile, and total peat depth across the sites. Peat depth ranges from 0.5-2 m, and is closely related to consistent groundwater discharge. We identified a suite of potential indicator species, and we are monitoring their distribution with respect to seasonal depth to water table. We are supplementing our field data collection with data from the published literature on depth to water table requirements of these plants. A combination of botanical, hydrologic, and edaphic data will be used to define the ideal and minimum depths to water table, and this information will be used in the "top-down" hydrologic model.

Commercial packages of spinach within 2 days of processing were cut open at one end, sprayed with fine mists of E. coli O157:H7 inoculum, resealed, and then stored at 1, 5, 8, and 12C for 12 days until their labeled best-if-used-by dates. Microbial enumeration and product quality evaluation were conducted on day(s) 0, 3, 6, 9, and 12 postinoculation. Spinach held at 12C supported significant (P < 0.001) E. coli O157:H7 growth, with a 1.0-log CFU/g increase within 3 days postinoculation, which was followed by additional growth during continued storage. E. coli O157:H7 grew slowly when held at 8C, with a significant (P < 0.01) level of growth reached after 6 days of storage. However, on products held at 1 and 5C, E. coli O157:H7 populations declined significantly (P < 0.01 and P < 0.001, respectively) within 3 days of storage. Aerobic mesophilic bacteria, psychrotrophic bacteria, and yeast and mold populations increased significantly at all storage temperatures, with more growth on products held at elevated temperatures. Product quality scores remained high within the first 6 days of storage, with a sharp decline noted on samples held at 12C on day 9. Results suggest that E. coli O157:H7 can grow significantly on commercially packaged spinach held at 8C or above before significant product quality deterioration occurs.

Rep-PCR has become a rapid and cost-effective method for genotyping fungi and bacteria. In the present study, we evaluated the discriminatory power of a semi-automated rep-PCR barcoding system to distinguish morphotypic species and compare the results with the data obtained from ITS and partial calmodulin regions. For this purpose, 20 morphotyped black-spored Aspergillus species were used to create the A. section Nigri library in this barcoding system that served to identify 34 field isolates. A pair-wise similarity matrix was calculated using the cone-based Pearson correlation method and the dendrogram was generated by the unweighted pair group method with arithmetic mean (UPGMA), illustrating four different clustered groups: the uniseriate cluster (I), the Aspergillus carbonarius cluster (II), and. the two A. niger aggregate clusters (named III.A and III.B). Rep-PCR showed higher resolution than the ITS and the partial calmodulin gene analytical procedures. The data of the 34 unknown field isolates, collected from different locations in the United States, indicated that only 12% of the field isolates were >95% similar to one of the genotypes included in the A. section Nigri library. However, 64% of the field isolates matched genotypes with the reference library (similarity values >90%). Based on these results, this barcoding procedure has the potential for use as a reproducible tool for identifying the black-spored aspergilli.

This perception is based primarily on short-term studies that have documented reductions in contaminant concentrations as runoff water passes through a wetland, but little is known about the long-term fate of scavenged contaminants. Evidence of long term processes can potentially be found retained in accumulated sediments where wetlands discharge into the quiescent waters of a lake. With this in mind, sediment cores from five different oxbow lakes and associated riparian wetlands have been sampled for trace element analysis from northwest Mississippi. This area, locally known as the Delta region, sits on the ancestral floodplain of the Mississippi River and was cleared of forests for agricultural use starting in the late 19 (super th) century. Lakes and surrounding wetlands in the Delta have had a long history of variable land use and influxes of a wide variety of agrichemicals. Sediment accumulation rates, based on (super 210) Pb and (super 137) Cs analyses, range from 0.2 to as high as 4.2 cm/yr, with well defined changes in rate corresponding to changes in land use. Trace element results obtained thus far indicate that each lake has its own unique history, dependent on the timing of clearing of surrounding lands, variability in surface water flows, and the types of agrichemicals used on adjacent fields. Some lakes show clear spikes of elements such as Pb, As and Co in open water sediments, with a complete absence of elevated concentrations in adjacent contemporaneous wetland sediments. These results suggest that at least some elements initially scavenged by the wetland are later remobilized and eventually flushed from the wetland. Other lakes contain very different records, with elevated concentrations of elements such as Cr and Zn appearing in both wetland and open water sediments deposited some time after the land was cleared.

As most contemporary research on lava flows is carried out in places with little surface water (e.g., Hawaii and Mt Etna), little work has been done on how lava flows influence the location and path of surface water. Here we use field observations, LiDAR imagery, bathymetric surveys, and geochemical analysis of lava samples to reconstruct the interplay between lava flows and surface water in the upper McKenzie River valley, Oregon. The head of the McKenzie River, Clear Lake, formed when lava flows from the Sand Mountain volcanic chain entered and dammed the ancestral McKenzie River from the east; the modern McKenzie River flows out of the southwestern end of Clear Lake. Lava flows at the lake's southern margin are covered by old growth forest, while relatively barren lava flows form the lake's eastern margin. The southern portion of the lake covers a submerged platform with drowned trees. These observations suggest that lava flows affected the Clear Lake area on at least two separate occasions: first, a lava flow dammed the river and created the lake, then later, a lava flow entered and raised lake levels. Upon exiting Clear Lake, the McKenzie River traverses Sand Mountain lava flows for 2.5 km. Initially, the river channel marks the boundary between a lava flow margin (east) and a Pleistocene graben-bounding fault (west). 1 km downstream of the outlet the channel crosses over the lava flow for 300 meters, then for the remainder of the traverse it marks the boundary between lava flows of two different eruptive events. These observations raise questions as to why the river crosses the lava flow after flowing along its margin, and where the channel was prior to and between the emplacements of its two bounding lava flows. Two waterfalls, both over 25 meters tall, mark lava flow fronts. These waterfalls have amphitheater shapes, presumably formed from plucking along joints and removal of material. Thus, in the upper McKenzie River valley, lava flows from the Sand Mountain volcanic belt (1) dammed the river, creating a lake, (2) dictated the location of the river channel, and (3) formed two large waterfalls. In the future, lava flows are likely to enter the valley again, further reorganizing the hydrology; lava flows are indeed powerful movers of surface water.

AN - 734123960; 19886451 AB - Tart cherry, Prunus cerasus L. variety Montmorency, fruit were infested with plum curculio, Conotrachelus nenuphar (Herbst) (Coleoptera: Curculionidae), and treated with insecticides to target late instars, neonates, and eggs. The organophosphates azinphos-methyl and phosmet and the neonicotinoid thiamethoxam reduced larval emergence rates by >90% for all life stage targets; after >30 d, few surviving larvae were found inside fruit. Acetamiprid and thiacloprid also had curative activity and yielded >75% reductions in emergence and few surviving larvae in the fruit after >30 d. The juvenile hormone analog pyriproxyfen reduced larval emergence, but 66% of fruit that was treated to target late-instars still had live larvae inside of them after >30 d. Novaluron, chlorantraniliprole, and esfenvalerate had no curative activity. Indoxacarb had limited curative activity, and all targeted life stages had larval emergence. Internal and external residues were analyzed and are discussed in relation to their penetration and curative potential. The curative activity of azinphos-methyl has played an important role in meeting federal standards for infestation-free tart cherries at processing. Regulatory changes are eliminating the use of this compound, and new integrated pest management programs for plum curculio will need to address the loss of azinphos-methyl's curative activity.

AN - 734123953; 19886449 AB - The western pine beetle, Dendroctonus brevicomis LeConte (Coleoptera: Curculionidae: Scolytinae), is a major cause of ponderosa pine, Pinus ponderosa Dougl. ex Laws., mortality in much of western North America. Currently, techniques for managing D. brevicomis infestations are limited. Verbenone (4,6,6-trimethylbicyclo [3.1.1] hept-3-en-2-one) is an antiaggregation pheromone of several Dendroctonus spp., including D. brevicomis, and it has been registered as a biopesticide for control of mountain pine beetle, Dendroctonus ponderosae Hopkins, and southern pine beetle, Dendroctonus frontalis Zimmermann. We evaluated the efficacy of a 5-g verbenone pouch [82%-(-); 50 mg/d] applied at 125 Ulha for protecting P. ponderosa stands (2 ha) from D. brevicomis attack over a 3-yr period. No significant differences in levels of D. brevicomis-caused tree mortality or the percentage of unsuccessfully attacked trees were found between verbenone-treated and untreated plots during each year or cumulatively over the 3-yr period. Laboratory analyses of release rates and chemical composition of volatiles emanating from verbenone pouches after field exposure found no deterioration of the active ingredient or physical malfunction of the release device. The mean release rate of pouches from all locations and exposure periods was 44.5 mg/d. In a trapping bioassay, the range of inhibition of the 5-g verbenone pouch was determined to be statistically constant 2 m from the release device. We discuss the implications of these and other results to the development of verbenone as a semiochemical-based tool for management of D. brevicomis infestations in P. ponderosa stands.

AN - 734101044; 19857112 AB - F1-2 and F1-5 are mouse IgG1 monoclonal antibodies that bind the heavy chain of Botulinum neurotoxin serotype A (BoNT/A). To characterize the epitopes of F1-2 and F1-5, three complementary experimental approaches were selected. First, recombinant peptide fragments of BoNT/A heavy-chain were used in Western blots to identify the epitope regions. Second, a peptide phage display library was used to identify specific amino acids bound by F1-2 and F1-5, and these amino acids were mapped onto the three-dimensional structure of BoNT/A. Third, selected amino acids were mutated to alanine and the effects of the mutations on F1-2 and F1-5 binding were evaluated. Data from recombinant peptide fragment binding experiments suggested that the epitopes for antibodies F1-2 and F1-5 are located between amino acids R564 and S793 on the toxin heavy chain. Furthermore, elimination of amino acids from the amino terminus (R564-K595), or from the carboxyl terminus (N759-S793) of this fragment abolished binding of both F1-2 and F1-5, suggesting a conformational epitope for these antibodies. Peptide sequences deduced from antibody binding to the peptide phage display library suggested that tyrosine residues located at positions 748, 750, and 753 might form a significant part of the F1-2 and F1-5 epitope motif. Mutation of Y750 or Y753 to alanine significantly reduced binding of either antibody, while mutation of Y748 to alanine had no effect on antibody binding. The nucleotide and deduced amino acid sequences of the variable regions of the heavy chains of F1-2 and F1-5 are reported. The complementarity determining regions (CDRs) of the heavy chains were found to be 78% identical. It is possible that F1-2 and F1-5 bind the same epitope via the common amino acids within their CDRs.

AN - 733578956; 19656903 AB - Selenium (Se) is an essential micronutrient for animals and humans but becomes toxic at high dosage. Biologically based Se volatilization, which converts Se into volatile compounds, provides an important means for cleanup of Se-polluted environments. To identify novel genes whose products are involved in Se volatilization from plants, a broccoli (Brassica oleracea var italica) cDNA encoding COQ5 methyltransferase (BoCOQ5-2) in the ubiquinone biosynthetic pathway was isolated. Its function was authenticated by complementing a yeast coq5 mutant and by detecting increased cellular ubiquinone levels in the BoCOQ5-2-transformed bacteria. BoCOQ5-2 was found to promote Se volatilization in both bacteria and transgenic Arabidopsis (Arabidopsis thaliana) plants. Bacteria expressing BoCOQ5-2 produced an over 160-fold increase in volatile Se compounds when they were exposed to selenate. Consequently, the BoCOQ5-2-transformed bacteria had dramatically enhanced tolerance to selenate and a reduced level of Se accumulation. Transgenic Arabidopsis expressing BoCOQ5-2 volatilized three times more Se than the vector-only control plants when treated with selenite and exhibited an increased tolerance to Se. In addition, the BoCOQ5-2 transgenic plants suppressed the generation of reactive oxygen species induced by selenite. BoCOQ5-2 represents, to our knowledge, the first plant enzyme that is not known to be directly involved in sulfur/Se metabolism yet was found to mediate Se volatilization. This discovery opens up new prospects regarding our understanding of the complete metabolism of Se and may lead to ways to modify Se-accumulator plants with increased efficiency for phytoremediation of Se-contaminated environments.

AN - 67660623; 19651864 AB - Adulteration of food or feed with any of the seven serotypes of botulinum neurotoxin (BoNT) is a potential bioterrorism concern. Currently, there is strong interest in the development of detection reagents, vaccines, therapeutics, and other countermeasures. A sensitive immunoassay for detecting BoNT serotype A (BoNT/A), based on monoclonal antibodies (MAbs) F1-2 and F1-40, has been developed and used in complex matrices. The epitope for F1-2 has been mapped to the heavy chain of BoNT/A, and the epitope of F1-40 has been mapped to the light chain. The ability of these MAbs to provide therapeutic protection against BoNT/A intoxication in mouse intravenous and oral intoxication models was tested. High dosages of individual MAbs protected mice well both pre- and postexposure to BoNT/A holotoxin. A combination therapy consisting of antibodies against both the light and heavy chains of the toxin, however, significantly increased protection, even at a lower MAb dosage. An in vitro peptide assay for measuring toxin activity showed that pretreatment of toxin with these MAbs did not block catalytic activity but instead blocked toxin entry into primary and cultured neuronal cells. The timing of antibody rescue in the mouse intoxication models revealed windows of opportunity for antibody therapeutic treatment that correlated well with the biologic half-life of the toxin in the serum. Knowledge of BoNT intoxication and antibody clearance in these mouse models and understanding of the pharmacokinetics of BoNT are invaluable for future development of antibodies and therapeutics against intoxication by BoNT.

AN - 67655700; 19543805 AB - Aspergillus species are increasingly important human pathogens. It is not known whether toxic metabolites of many of these pathogenic species can act as virulence factors in aspergillosis. We examined isolates of aflatoxin and ochratoxin-producing species for toxin production in ex vivo conditions. Seven of the 21 aflatoxin-producing isolates screened produced aflatoxin at 35 and 37 degrees C on the general medium yeast extract sucrose agar (YES). However, none of them produced toxin at these temperatures on brain heart infusion agar (BHA), a medium that mimics human tissue, or on BHA with modified pH or sugar levels. Six of the 12 ochratoxin-producing isolates examined produced toxin at 35 degrees C on YES. All three isolates of A. alliaceus produced ochratoxin on BHA or modified BHA at 37 degrees C. One strain of A. pseudoelegans produced a minute amount of ochratoxin on modified BHA at 37 degrees C. These data indicate that aflatoxin is an unlikely virulence, factor but that ochratoxin may be a potential virulence factor in aspergillosis.

AN - 67652276; 19708884 AB - The purpose of this study was to determine the proficiency of supplements to enhance the recovery of Salmonella from heat-treated liquid egg albumen on solid agar media. Salmonella-inoculated albumen, heated at 53.3 degrees C for 4 min, was plated on 39 combinations of solid media with or without the addition of 12 supplements. Greater numbers of Salmonella (P < 0.05) recovered with the addition of 1.0 g l(-1) ferrous sulfate (FeSO(4)) than with any other supplements, except for 0.5 or 1.0 g l(-1) 3'3'-thiodipropionic acid (TDP), which recovered equivalent populations. Addition of 1.0 g l(-1) sodium pyruvate or 6.0 g l(-1) yeast extract plus 1.0 g l(-1) sodium pyruvate supported greater resuscitation than unsupplemented tryptic soy agar (TSA) or supplementing with 0.01 or 0.1 g l(-1) N-propyl gallate, 10 g l(-1) activated charcoal, 0.1 g l(-1) KMnO(4) or 50 mg l(-1) ethoxyquin. The remaining supplements supported recovery of equivalent numbers of Salmonella, which were fewer cells than recovered with 1.0 g l(-1) FeSO(4), yet greater populations than recovered with 50 mg l(-1) ethoxyquin. Supplementation of plating media with FeSO(4), TDP or sodium pyruvate enhanced recovery of sublethally injured Salmonella from albumen. Pasteurizing albumen impedes recovery of pathogens. These results suggest that the addition of supplements to plating media may assist resuscitation and colony development of heat-injured salmonellae.

AN - 67642820; 19548292 AB - Psocids are emerging pests in stored products, particularly in amylaceous commodities such as grains. Currently, their control is based on the use of fumigants and contact insecticides; however, newer data indicate that psocids are tolerant to insecticides used to control other stored-grain species. This study evaluated the insecticides registered in the USA for use on stored maize, rice and wheat for control of the psocid species Lepinotus reticulatus, Liposcelis entomophila, L. bostrychophila and L. paeta. Mortality of exposed adult females was recorded after 7 and 14 days of exposure, while progeny production was assessed after 30 days of exposure. On wheat and rice, chlorpyriphos-methyl + deltamethrin was generally more effective against exposed parental adults than spinosad or pyrethrin, while pirimiphos-methyl was more effective on maize than spinosad or pyrethrin. In most cases, progeny production was suppressed in the treated grains. Progeny production was consistently lowest on wheat and rice treated with chlorpyriphos-methyl + deltamethrin and maize treated with pirimiphos-methyl. Chlorpyriphos-methyl + deltamethrin and pirimiphos-methyl were the most effective insecticides for all species and commodities. Conversely, efficacy of spinosad or pyrethrum was highly dependent on the psocid species and commodity. Copyright 2009 by John Wiley & Sons, Ltd.

AN - 67595535; 19263001 AB - Our previous studies have shown that selenium (Se) is protective against dimethylhydrazine (DMH)-induced preneoplastic colon cancer lesions, and protection against DNA damage has been hypothesized to be one mechanism for the anticancer effect of Se. The present study was designed to determine whether dietary selenite affects somatic mutation frequency in vivo. We used the Big Blue transgenic model to evaluate the in vivo mutation frequency of the cII gene in rats fed either a Se-deficient (0 microg Se/g diet) or Se-supplemented diet (0.2 or 2 microg Se/g diet; n = 3 rats/diet in experiment 1 and n = 5 rats/group in experiment 2) and injected with DMH (25 mg/kg body weight, i.p.). There were no significant differences in body weight between the Se-deficient and Se-supplemented (0.2 or 2 microg Se/g diet) rats, but the activities of liver glutathione peroxidase and thioredoxin reductase and concentration of liver Se were significantly lower (p < 0.0001) in Se-deficient rats compared to rats supplemented with Se. We found no effect of dietary Se on liver 8-hydroxy-2'-deoxyguanosine. Gene mutation frequency was significantly lower in liver (p < 0.001) than that of colon regardless of dietary Se. However, there were no differences in gene mutation frequency in DNA from colon mucosa or liver from rats fed the Se-deficient diet compared to those fed the Se-supplemented (0.2 or 2 microg Se/g diet) diet. Although gene mutations have been implicated in the etiology of cancer, our data suggest that decreasing gene mutation is not likely a key mechanism through which dietary selenite exerts its anticancer action against DMH-induced preneoplastic colon cancer lesions in a Big Blue transgenic rat model.

AN - 67568688; 19577617 AB - Aldehyde inhibitors such as furfural, 5-hydroxymethylfurfural, anisaldehyde, benzaldehyde, cinnamaldehyde, and phenylaldehyde are commonly generated during lignocellulosic biomass conversion process for low-cost cellulosic ethanol production that interferes with subsequent microbial growth and fermentation. In situ detoxification of the aldehyde inhibitors is possible by the tolerant ethanologenic yeast that involves multiple genes including numerous functional reductases. In this study, we report a novel aldehyde reductase gene clone Y63 from ethanologenic yeast Saccharomyces cerevisiae NRRL Y12632, representing the uncharacterized ORF YGL157W, which demonstrated NADPH-dependent reduction activities toward at least 14 aldehyde substrates. The identity of gene clone Y63 is the same with YGL157W of SGD since a variation of only 35 nucleotides in genomic sequence and three amino acid residues were observed between the two that share the same length of 347 residues in size. As one among the highly induced genes, YGL157W of Y-12632 showed significantly high levels of transcript abundance in response to furfural and HMF challenges. Based on the deduced amino acid sequence and the most conserved functional motif analyses including closely related reductases from five other yeast species to this date, YGL157W was identified as a member of the subclass 'intermediate' of the SDR (short-chain dehydrogenase/reductase) superfamily with the following typical characteristics: the most conserved catalytic site to lie at Tyr(169)-X-X-X-Lys(173); an indispensable reduction catalytic triad at Ser(131), Tyr(169), and Lys(173), and an approved cofactor-binding motif at Gly(11)-X-X-Gly(14)-X-X-Ala(17) near the N-terminus. YGL039W, YDR541C, and YOL151W (GRE2) appeared to be the similar type of enzymes falling into the same category of the intermediate subfamily.

The objectives of this study were to (1) assess the magnitude of denitrification enzyme activity (DEA) in the suspended sludge layers of bulrush and cattail treatment wetlands, and (2) evaluate the impact of nitrogen pretreatment on DEA in the suspended sludge layer. The study used four wetland cells (3.6mx33.5m) with two cells connected in series. Each wetland series received either untreated or partially nitrified swine wastewater from a single-cell anaerobic lagoon. The DEA of the suspended sludge layers of the constructed wetlands was measured by the acetylene inhibition method. The control DEA treatment for the sludge layer had a mean rate of 18 mu gN sub(2)O-Ng super(-) super(1)sludgeh super(-) super(1). Moreover, the potential DEA (nitrate-N and glucose-C added) mean was very large, 121 mu gN sub(2)O-Ng super(-) super(1)sludgeh super(-) super(1). These DEA rates are consistent with the previously reported high levels of nitrogen removal by denitrification from these wetlands, especially when the wastewater was partially nitrified. Stepwise regression using distance within the wetland, wastewater nitrate, and wastewater ammonia explained much of the variation in DEA rates. In both bulrush and cattail wetlands, there were zones of very high potential DEA.

Cattle (n = 319) were distributed in 10 adjacent pens, and fecal and hide levels of E. coli O157:H7 were monitored. When the fecal pen prevalence exceeded 20%, the hide pen prevalence was usually (25 of 27 pens) greater than 80%. Sixteen of 19 (84.2%) supershedder (>104 CFU/g) pens had a fecal prevalence greater than 20%. Significant associations with hide and high-level hide (40 CFU/100 cm2) contamination were identified for (i) a fecal prevalence greater than 20%, (ii) the presence of one or more high-density shedders (200 CFU/g) in a pen, and (iii) the presence of one or more supershedders in a pen. The results presented here suggest that the E. coli O157:H7 fecal prevalence should be reduced below 20% and the levels of shedding should be kept below 200 CFU/g to minimize the contamination of cattle hides. Also, large and unpredictable fluctuations within and between pens in both fecal and hide prevalence of E. coli O157:H7 were detected and should be used as a guide when preharvest studies, particularly preharvest intervention studies, are designed.

Given that B. pertussis is thought to have derived from a Bordetella bronchiseptica-like ancestor, we hypothesized that growth phase-dependent gene regulation would also occur in B. bronchiseptica. Microarray analysis revealed and quantitative real-time PCR (qRT-PCR) confirmed that growth phase-dependent gene regulation occurs in B. bronchiseptica, resulting in prominent temporal shifts in global gene expression. Two virulence phenotypes associated with these gene expression changes were tested. We found that growth-dependent increases in expression of some type III secretion system (TTSS) genes led to a growth phase-dependent increase in a TTSS-dependent function, cytotoxicity. Although the transcription of genes encoding adhesins previously shown to mediate adherence was decreased in late-log and stationary phases, we found that the adherence of B. bronchiseptica did not decrease in these later phases of growth. Microarray analysis revealed and qRT-PCR confirmed that growth phase-dependent gene regulation occurred in both Bvg+ and Bvg- phase-locked mutants, indicating that growth phase-dependent gene regulation in B. bronchiseptica can function independently from the BvgAS regulatory system.

A related human pathogen, Haemophilus influenzae, has been better studied, and many of its virulence factors have been identified. Two of these, outer membrane proteins P2 and P5, are known to have important virulence properties. The goals of this study were to identify, analyze, and compare the genetic relatedness of orthologous genes encoding P2 and P5 proteins in a diverse group of 35 H. parasuis strains. Genes encoding P2 and P5 proteins were detected in all H. parasuis strains evaluated. The predicted amino acid sequences for both P2 and P5 proteins exhibit considerable heterogeneity, particularly in regions corresponding to predicted extracellular loops. Twenty-five variants of P2 and 17 variants of P5 were identified. The P2 proteins of seven strains were predicted to contain a highly conserved additional extracellular loop compared to the remaining strains and to H. influenzae P2. Antigenic-site predictions coincided with predicted extracellular loop regions of both P2 and P5. Neighbor-joining trees constructed using P2 and P5 sequences predicted divergent evolutionary histories distinct from those predicted by a multilocus sequence typing phylogeny based on partial sequencing of seven housekeeping genes. Real-time reverse transcription-PCR indicated that both genes are expressed in all of the strains.

Franco var. menziesii] using allozyme and microsatellite markers AN - 21334300; 12040433 AB - Characterizing population structure using neutral markers is an important first step in association genetic studies in order to avoid false associations between phenotypes and genotypes that may arise from non-selective demographic factors. Population structure was studied in a wide sample of ~1,300 coastal Douglas-fir [Pseudotsuga menziesii (Mirb.) Franco var. menziesii] trees from Washington and Oregon. This sample is being used for association mapping between cold hardiness and phenology phenotypes and single-nucleotide polymorphisms in adaptive-trait candidate genes. All trees were genotyped for 25 allozyme and six simple sequence repeat (SSR) markers using individual megagametophytes. Population structure analysis was done separately for allozyme and SSR markers, as well as for both datasets combined. The parameter of genetic differentiation (c or F ST) was standardized to take into account high within-population variation in the SSR loci and to allow comparison with allozyme loci. Genetic distance between populations was positively and significantly correlated with geographic distance, and weak but significant clinal variation was found for a few alleles. Although the STRUCTURE simulation analysis inferred the same number of populations as used in this study and as based on previous analysis of quantitative adaptive trait variation, clustering among populations was not significant. In general, results indicated weak differentiation among populations for both allozyme and SSR loci (c s=0.006--0.059). The lack of pronounced population subdivision in the studied area should facilitate association mapping in this experimental population, but we recommend taking the STRUCTURE analysis and population assignments for individual trees (Q-matrix) into account in association mapping.

GPR is geophysical tool which uses an antenna to propagate short bursts of electromagnetic energy in solid materials and measure the two-way travel time and amplitude of reflected signals. We compared estimates of bole decay from data collected with a SIR 3000 GPR system equipped with a 900 MHz antenna to measurements of decay from stem cross sections and increment cores for three conifer species (Pseudotsuga menziesii, Thuja plicata and Tsuga heterophylla). We found that near-surface decay, air-filled voids and desiccated boles had unique electromagnetic signatures, which could be separated from other defects. GPR successfully estimated the percent area of air-filled cavities and was not significantly different than results from destructive sampling. However, separation of incipient to severe decay from benign reflectors (e.g. moisture gradient between sapwood and heartwood) in conifers was much less diagnostic than with angiosperms. A limited assessment of Acer saccharum showed that GPR has potential to detect defects in angiosperms; however, more research is needed to outline the full range of detectable defects. Based on the trees in this study, the potential for GPR to detect decay-related defects in conifers seems limited. Despite problems detecting decay, reflections originating from the sapwood : heartwood boundary may prove useful to determine thickness of functional sapwood in conifers, but accurate quantification will require further technical development.

These dominant forests have displaced native vegetation in sensitive wetland systems. We hypothesized that native plant diversity would increase following recent reductions in density of mature melaleuca stands in south Florida. We therefore examined data on changes in melaleuca densities and plant species diversity derived from permanent plots that were monitored from 1997 to 2005. These plots were located within mature melaleuca stands in nonflooded and seasonally-flooded habitats. Two host-specific biological control agents of melaleuca, Oxyops vitiosa and Boreioglycaspis melaleucae, were introduced during 1997 and 2002, respectively. Also, an adventive rust fungus Puccinia psidii and lobate-lac scale Paratachardina pesudolobata became abundant during the latter part of the study period. Overall melaleuca density declines in current study coincided with two to four fold increases in plant species diversity. The greatest declines in melaleuca density as well as the greatest increases in family importance values and species diversity indices occurred in nonflooded as compared to seasonally-flooded habitats. Most pioneer plant species in study sites belonged to Asteraceae, Cyperaceae, Poaceae, and Ulmaceae. The rapid reduction in melaleuca density and canopy cover during the study period may be attributed to self-thinning accelerated by the negative impact of natural enemies. Densities of other woody plants, particularly Myrica and Myrsine, which were sparsely represented in the understory by a few suppressed individuals also declined during the same period, possibly due to infestation by the generalist lac-scale. These findings indicate that natural-enemy accelerated self-thinning of melaleuca densities is positively influencing the native plant diversity and facilitating the partial rehabilitation of degraded habitats.

Using Near-infrared Spectroscopy AN - 21279868; 11848150 AB - Determining malaria vector species and age is crucial to measure malaria risk. Although different in ecology and susceptibility to control, the African malaria vectors Anopheles gambiae sensu stricto and An. arabiensis are morphologically similar and can be differentiated only by molecular techniques. Furthermore, few reliable methods exist to estimate the age of these vectors, which is a key predictor of malaria transmission intensity. We evaluated the use of near-infrared spectroscopy (NIRS) to determine vector species and age. This non-destructive technique predicted the species of field-collected mosquitoes with approximately 80% accuracy and predicted the species of laboratory-reared insects with almost 100% accuracy. The relative age of young or old females was predicted with approximately 80% accuracy, and young and old insects were predicted with . 90% accuracy. For applications where rapid assessment of the age structure and species composition of wild vector populations is needed, NIRS offers a valuable alternative to traditional methods.

We analyzed PG extracts of the following green lacewings from North and South America, Australia, and China: Ceraeochrysa cubana (Brazil); Chrysopa (= Co.) oculata, Co. nigricornis, Co. incompleta, Co. quadripunctata (USA), and Co. septempunctata (China); Chrysoperla (= Cl.) rufilabris (USA) and Cl. sp. (Brazil); Plesiochrysa ramburi and Mallada spp. (Australia). PG secretions are characteristic for species within a genus, except for Chrysopa spp. (Z)-4-Tridecene is ubiquitous, but (Z,Z)-4,7-tridecadiene is a major PG constituent in some Chrysopa spp. and in P. ramburi. Earlier reports that Co. oculata and Co. nigricornis produce 1-tridecene were shown to be in error. Chrysopa PG secretions are distinguished by the presence or absence of N-3-methylbutylacetamide, plus skatole (3-methylindole). Skatole is also identified for the first time from the Plesiochrysa and Ceraeochrysa. The PG secretion in Plesiochrysa ramburi is characterized by the presence of (Z)-4-undecene instead of (Z)-4-tridecene, and N-3-methylbutylpropanamide instead of the acetamide, resembling the PG secretions of Chrysopa nigricornis, Co. septempunctata and Co. incompleta. The chemotaxonomic value of PG semiochemicals is discussed, including evidence for subgroups within the genus Chrysopa as it now stands.

Swainsonine accumulates in all parts of the plant with the highest concentrations found in the above ground parts. A fungal endophyte, Undifilum oxytropis, found in locoweed plant species, is responsible for the synthesis of swainsonine. By using quantitative PCR, the endophyte can be quantified in locoweed species. Endophyte amounts differ between plant parts and in some instances do not mirror the concentrations of swainsonine in the corresponding parts. Two groups of Oxytropis sericea were identified: one that accumulated high concentrations of swainsonine and another where swainsonine was not detected, or concentrations were near the detection threshold. The plants with high swainsonine concentrations had quantitatively higher amounts of endophyte. Alternatively, plants with low or no swainsonine detected had quantitatively lower endophyte amounts. In addition, swainsonine and endophyte concentrations were not distributed uniformly within the same plant when separated into stalks (leaves, scape(s), and flowers/pods). These findings provide evidence as to why plants in the same population accumulate different concentrations of swainsonine, and they have important implications for sampling of locoweed plants.

However, displacing this bait 4-16m horizontally from the trap significantly increased its synergistic effect. (+)-endo-Brevicomin enhanced catch to the same degree when the bait was positioned either on the trap or 32m away. In another experiment, pairs of frontalin/turpentine-baited traps were established with 4m spacing between traps and >100m spacing between pairs. Attachment of either a racemic or (+)-endo-brevicomin bait to one trap of a pair caused a significant increase in catch by both traps, but catch in the trap lacking endo-brevicomin was increased more than in its endo-brevicomin-baited twin. In a third experiment, widely-spaced groups of three traps (in a line with 1 and 4m spacing between the middle and outer traps) were baited uniformly with frontalin and turpentine, and the release rate of (+)-endo-brevicomin from the middle trap was varied across three orders of magnitude. Release rates sufficient to enhance total D. frontalis catch by the trio also caused relatively higher catches to occur in the outer traps than in the middle one. These experiments indicated that both male and female D. frontalis fly to and land preferentially at sources of frontalin and host odors when these are located some distance away from a source of endo-brevicomin. This behavior may have evolved in D. frontalis to allow host-seeking beetles to locate growing, multi-tree infestations while avoiding fully-colonized trees within these infestations. Our data demonstrate that trap spacing alone can qualitatively change the outcome of bait evaluation trials and may explain why many earlier experiments with endo-brevicomin failed to identify it as an aggregation pheromone synergist for D. frontalis. We believe that important aggregative functions of semiochemicals of other bark beetle species may have been similarly overlooked due to choice of experimental procedures.

AN - 21264526; 11839733 AB - Salt cedar trees with pronounced witches'-broom symptoms were observed in their natural habitat in China. 16S rRNA gene sequences unique to phytoplasmas were detected in every DNA sample extracted from stem and leaf tissues of the symptomatic trees, revealing a direct association between phytoplasma infection and the salt cedar witches'-broom (SCWB) disease. Phylogenetic analysis of the SCWB phytoplasma 16S rRNA gene sequence indicated that the SCWB phytoplasma belonged to a subclade consisting of several mutually distinct 'Candidatus Phytoplasma' taxa including 'Ca. Phytoplasma prunorum', 'Ca. Phytoplasma mali', 'Ca. Phytoplasma pyri' and 'Ca. Phytoplasma spartii'. Pairwise sequence similarity scores calculated from an alignment of near full-length 16S rRNA genes revealed that SCWB phytoplasma shared 96.6 % or less sequence similarity with each previously described or proposed 'Ca. Phytoplasma' taxon, justifying the recognition of SCWB phytoplasma as a novel taxon, 'Candidatus Phytoplasma tamaricis'. The distinct virtual RFLP pattern derived from the SCWB phytoplasma 16S rRNA gene sequence, together with its lower-than-threshold similarity coefficient values with RFLP patterns of any of the 29 previously established groups, supported the recognition of a new 16Sr group, designated 16SrXXX, salt cedar witches'-broom phytoplasma group.

On the basis of phylogenetic analysis of 16S rRNA gene sequences, morphological observations and the presence of LL-diaminopimelic acid as the diagnostic diamino acid in whole-cell hydrolysates, the new isolates clearly belonged to the genus Streptomyces. Analyses of the phylogenetic positions of strains NRRL B- 24165 super(T) and NRRL B-24166 super(T) based on 16S rRNA gene sequences of all recognized species of the genus Streptomyces, as well as evaluation of morphological and physiological characteristics, demonstrated that the new isolates could be differentiated from all recognized species and therefore represented novel species. It is proposed that the new strains represent two novel species for which the names Streptomyces atriruber sp. nov. (type strain NRRL B-24165 super(T)=DSM 41860 super(T)=LDDC 6330-99 super(T)) and Streptomyces silaceus sp. nov. (NRRL B-24166 super(T)=DSM 41861 super(T)=LDDC 6638-99 super(T)) are proposed. The species names are based on the distinctive colours of the substrate mycelium of these strains, dark red and deep orange- yellow, respectively.

Although there are several reports of fungal pathogens in psyllids, there are none from B. cockerelli, nor have any fungi been evaluated against it. Five isolates of fungi, one Beauveria bassiana, two Metarhizium anisopliae and two Isaria fumosorosea, were bioassayed against B. cockerelli on potato leaves under ideal conditions for the fungi. All applications were made with a Potter spray tower. With the exception of concentration-effect studies, all other applications were made using 107 conidia/mL in a 2-mL aqueous suspension. All isolates except B. bassiana, produced 95-99% mortality, corrected for control mortality, in adults 2-3 days after application of conidia and 91-99% in nymphs 4 days after application. The corrected mortalities for adults and nymphs treated with B. bassiana were 53 and 78%, respectively, 4 days after application. I. fumosorosea Pfr 97 produced 95% corrected mortality in both first and late third instar nymphs. M. anisopliae (F 52) produced 96% corrected mortality in first and third instar nymphs. Pfr 97 and F 52 were evaluated for insecticidal activity against third instar B. cockerelli using 105, 106, and 107 conidia per mL. Mortality produced by I. fumosorosea Pfr 97 ranged from 83 to 97% and that of M. anisopliae F 52 was 88 to 95% at these concentrations.

No-choice tests, native range field surveys and non-target host exposures were used to determine the fundamental host range of the scale collected from Caloma, Spain and Perpignan, France. Thirty-five species, including two genotypes of A. donax and seven ecotypes of Phragmites australis, along with closely related grasses, economic grasses and habitat associates were tested. In quarantine no-choice testing using releases of 200 crawlers per plant, normal development of R. donacis was observed on A. donax and A. formosana, with very limited survival to the adult stage on Spartina alterniflora and Leptochloa spp. In follow-up studies using 1000 crawlers per plant, 10 live adult females were found on Leptochloa virgata, and one adult female on Spartina alterniflora, but average adult female abundance per plant was (2580%) 26-times lower on L. virgata and over (39,090%) 100-times lower on S. alterniflora than on A. donax. Field surveys were conducted at five locations in Spain and France at which A. donax infested with R. donacis, co-occurred with two non-target species of concern and R. donacis was only found on A. donax. Six-month field host exposures in Spain using potted Leptochloa plants entwined with heavily infested A. donax confirmed that R. donacis is specific to Arundo under field conditions. Based on our results, the scale R. donacis appears to be specific to the genus Arundo and is unlikely to harm native or cultivated plants in the Americas.

The US has a large amount of surplus soybean oil annually, and using vegetable oils or their component fatty acids as starting material provides a new opportunity for bioindustry. Vegetable oils are relatively inexpensive and can be used to manufacture value-added products such as oxygenated oils and fatty acids. Oxygenated fatty acids are common in nature and are important industrial materials. They exist both in mammals and plants. Microorganisms oxidize fatty acids either at the terminal carbon or inside of the acyl chain to produce hydroxyl or keto fatty acids. In our continuing effort to produce value-added products from vegetable oils, we discovered more than one dozen novel oxygenated fatty acids through biotransformation. Microbial hydratase is a carbon 10 positional specific enzyme. Many of these new oxygenated fatty acids possess physiological activities and can be used as biomedicals, in addition to their known applications such as specialty chemicals. The position of hydroxyl groups on the fatty acyl carbon chain plays an important role in the activity against certain specific plant pathogenic fungi. Bacillus megaterium ALA2 converted polyunsaturated fatty acids (PUFA) in different ways. It converted [Omega]-6 PUFAs to a mixture of diepoxy bicyclic, tetrahydrofuranyl rings, and/or trihydroxy groups in their molecules while the products from [Omega]-3 PUFAs produced only hydroxyl tetrahydrofuranyl ring products. The monooxygenase gene of strain ALA2 was sequenced and is a soluble, self-sufficient P450 sub(BM-3) subclass that was highly homologous with the wild-type protein.

This laboratory study was designed to compare an untreated control and a 10-mg/L copper sulfate (CuSO sub(4)) treatment to control fungus (Saprolegnia spp.) on eggs of channel catfish Ictalurus punctatus at 23.5C in a flow-through system. The eggs were treated once daily until the embryos reached the eyed stage (five treatments). When hatching was complete for all viable eggs (day 10), the fry were counted to determine the percent survival in each treatment. Infestation by a fungus identified morphologically and by polymerase chain reaction as Saprolegnia spp. was severe in the control fish, resulting in 8% survival. The mean percent survival of fry hatched from the CuSO sub(4)-treated eggs was significantly higher (mean, 55%; range, 27-71%).

The aim of the study depended on monitoring of selected castle rocks showing instability problems due to extremely slow displacements of creep character. Apart from traditional methods of investigation at one test site (Spis Castle), authors implemented in their work the study of thermal expansion of the rocks as a result of seasonal periodic temperature changes having potential influence on displacements and numerical modeling in order to understand better the landslide failure mechanism. The results obtained from all study sites confirmed that even slow movements have to be implemented into preservation and stabilization works in order to safeguard the sites of great historic value.

The results from our previous studies demonstrated that saturated and polyunsaturated fatty acids reciprocally modulate the activation of TLR4. However, the underlying mechanism has not been understood. Here, we report for the first time that the saturated fatty acid lauric acid induced dimerization and recruitment of TLR4 into lipid rafts, however, dimerization was not observed in non-lipid raft fractions. Similarly, LPS and lauric acid enhanced the association of TLR4 with MD-2 and downstream adaptor molecules, TRIF and MyD88, into lipid rafts leading to the activation of downstream signaling pathways and target gene expression. However, docosahexaenoic acid (DHA), an n-3 polyunsaturated fatty acid, inhibited LPS- or lauric acid- induced dimerization and recruitment of TLR4 into lipid raft fractions. Together, these results demonstrate that lauric acid and DHA reciprocally modulate TLR4 activation by regulation of the dimerization and recruitment of TLR4 into lipid rafts. In addition, we showed that TLR4 recruitment to lipid rafts and dimerization were coupled events mediated at least in part by NADPH oxidase-dependent reactive oxygen species generation. These results provide a new insight in understanding the mechanism by which fatty acids differentially modulate TLR4-mediated signaling pathway and consequent inflammatory responses which are implicated in the development and progression of many chronic diseases.

We compared spatial predictions for 12 fuel and forest structure variables across three regions in the western United States using gradient nearest neighbor (GNN) imputation, linear models (LMs), classification and regression trees (CART), and geostatistical methods (kriging and universal kriging (UK)). Local-scale map accuracy varied considerably across sites, variables, and methods. GNN performed best for forest structure variables in Oregon, but LMs and UK were better for canopy variables and for forest structure variables in Washington and California. Kriging performed poorly throughout, and kriging did not improve prediction accuracy when added to LMs as UK. GNN outperformed CART in predicting vegetation classes and fuel models, complex variables defined by multiple attributes. Regional distributions of vegetation classes and fuel models were accurately represented by GNN and very poorly by CART and LMs. Despite their often limited accuracy at the local scale, GNN maps are useful when information on a wide range of forest attributes is needed for analysis and forest management at intermediate, i.e., landscape to ecoregional, scales.Original Abstract: Les amenagistes du territoire ont besoin d'informations fideles au sujet de la distribution geographique des combustibles en milieu naturel et de la structure de la foret sur de vastes regions pour evaluer le risque d'incendie et planifier les traitements des combustibles. Nous avons compare les predictions spatiales pour 12 variables reliees aux combustibles et a la structure de la foret dans trois regions de l'ouest des Etats-Unis en utilisant l'imputation par l'analyse de gradient du plus proche voisin (AGPV), des modeles lineaires (ML), des arbres de regression et de classification (ARC) et des methodes geostatistiques (krigeage et krigeage universel (KU)). La precision des cartes locales variait considerablement selon les stations, les variables et les methodes. L'imputation par l'AGPV avait la meilleure performance pour les variables de la structure de la foret en Oregon mais les ML et le KU etaient meilleurs pour les variables du couvert et de la structure de la foret dans l'Etat de Washington et la Californie. Le krigeage a donne des resultats mediocres dans tous les cas et n'ameliorait pas la precision lorsqu'il etait ajoute aux ML sous forme de KU. L'imputation par l'AGPV etait meilleure que les ARC pour predire les classes de vegetation et les modeles de combustibles, des variables complexes definies par de multiples attributs. La distribution regionale des classes de vegetation et des modeles de combustibles etait correctement representee par l'imputation par l'AGPV et tres inadequatement par les ARC et les ML. Malgre une precision souvent limitee a l'echelle locale, les cartes produites a partir de l'imputation par l'AGPV sont utiles lorsque des informations sur une large gamme d'attributs de la foret sont necessaires pour l'analyse et l'amenagement forestier a des echelles intermediaires allant du paysage a l'ecoregion.

We have tested lepidopteran-toxic B. thuringiensis strains with diverse substrate utilization profiles for the ability to survive repeated passages through larvae of the gypsy moth, Lymantria dispar, without intervening growth on artificial media. These experiments have revealed a remarkable correlation between the production of urease by the bacteria and its ability to survive repeated passages through larvae. Of 26 urease-positive strains tested, 23 were capable of surviving five passages through gypsy moth larvae. In contrast, none of the 24 urease- negative strains tested survived to the 4th passage, with only three strains surviving to the 3rd passage. Selection of B. thuringiensis strains with phenotypic traits favoring replication in the environment, such as urease production, may improve their efficacy as biological control agents.

Genetic structure was quantified at three spatial scales: (1) within apparent clones (intrapatch), (2) among clones within a field, and (3) among fields separated by as much as 65 km. Of five 'clones' or putative individuals examined in the intrapatch study, two showed complete genetic homogeneity within the patch, while three showed some band differences at their edges compared with their interiors. These differences at the edges, however, matched adjacent clones (so-called 'intruders'), from which it was concluded that lowbush blueberry exhibits a fairly tight, phalanx clonal architecture with no evidence of invasive seedling establishment within clones. No significant correlation between genetic and physical distance was found among clones within fields via several statistical approaches. Significant among-field genetic differentiation was found via AMOVA ( sub(PT) = 8.4%; p , 0.01) based upon transect samples across four fields ranging from 12.5 to 65 km apart. Principal component analysis and spatial autocorrelation (SA) corroborated these findings. Significant positive SA was found at the within-field distance class of <350 m, but SA decreased to an insignificant value by the first interfield distance of 12.5 km. A special form of SA analysis was employed to detect 'hotspots' of genetic similarity between pairs of adjacent clones in two fields. Results indicated that 5 of 23 pairs of clones (21.7%) were genetically similar to each other, while the majority of pairs (18 of 23; 78.3%) showed random, decreasing patterns of genetic similarity. Results are discussed in terms of clonal dynamics including architecture, seedling recruitment, and inferred pollen or seed dispersal distances. resumes individus examines, deux montrent une complete homogeneite genetique dans la talle, alors que trois montrent quelques differences de bandes a leur pourtour comparativement a leurs centres. Cependant, ces differences aux pourtours correspondent a des clones adjacents nommes ' intrus ', ce qui permet de conclure que le bleuet nain montre une architecture clonale de type phalanx assez serree, sans trace d'etablissement de plantules invasives dans les clones. On ne trouve aucune correlation significative pour les distances genetiques et geographiques entre les clones d'un meme champ, selon plusieurs approches statistiques. Le test AMOVA indique des differenciations genetiques significatives ( sub(PT) = 8,4 %; p , 0.01) entre champs, sur la base de transects echantillonnes dans quatre champs separes de 12,5 a 65 km. L'analyse en coordonnees principales et l'autocorrelation spatiale (SA) corroborent ces constatations. On observe une SA positive pour la classe de distance intra champ <350 m, mais qui diminue pour atteindre une valeur non significative a partir de la premiere distance entre champs de 12,5 km. Les auteurs ont utilise une forme speciale d'analyse SA, pour detecter des ' regions sensibles ' de similarite genetique entre des paires de clones adjacents dans deux champs. Les resultats indiquent que 5 des 23 paires de clones (21,7 %) sont genetiquement similaires entre elles, alors que la majorite des paires (18 de 23; 78,3 %) montrent un patron aleatoire de diminution de la similarite genetique. On discute les resultats en termes de dynamique clonale incluant l'architecture, de recrutement de plantules et de deduction des distances de dispersion des pollens et des graines.

(Euphorbiaceae) reproduces by vegetative and sexual means, characteristics that are key to its persistence and survival. In this study, we examined environmental effects on regrowth and flowering under controlled conditions to further validate field observations and set the stage for the future identification of molecular mechanisms involved in the regulation of these processes. Shoot cuttings were exposed to different combinations of decreasing temperatures, decreasing photoperiods, and vernalization, in growth chambers. Subsequently, shoots were removed and regrowth and flowering from new shoots were monitored in a warm temperature greenhouse under long-day conditions. Vernalization alone has no effect on regrowth and flowering. Plants required decreasing temperature followed by vernalization for rapid regrowth and flowering. Decreasing photoperiod at a constant temperature with or without vernalization had no significant effect on regrowth and flowering. In conjunction with previous field research, the results suggest that a gradually decreasing temperature is required as one of the components for flowering competence and vernalization is determinate for reproductive development under long-day conditions.Original Abstract: La plante adventice herbacee perenne Euphorbia esula L. (Euphorbiaceae) se reproduit par des moyens vegetatifs et sexuels, des caracteristiques qui constituent une cle pour sa persistance et sa survie. Les auteurs ont examine les effets environnementaux sur le bouturage et la floraison sous des conditions controlees, pour confirmer les observations de terrain et mettre en place ce qui est requis pour identifier les mecanismes moleculaires impliques dans la regulation de ces processus. Ils ont expose des boutures a differentes combinaisons de temperatures decroissantes, de photoperiodes decroissantes et de vernalisation en chambres de culture. Par apres, on a preleve les tiges et on a suivi leur reprise ainsi que la floraison sur les nouvelles tiges, dans une serre a temperature chaude sous des conditions de jours longs. La vernalisation a elle seule demeure sans effet sur la floraison. Les plantes necessitent une temperature descendante suivie d'une vernalisation pour une reprise rapide avec floraison. Une diminution de la photoperiode a temperature constante avec ou sans vernalisation reste sans effet significatif sur la reprise et la floraison. Avec ceux de recherches antecedentes sur le terrain, ces resultats suggerent qu'une diminution graduelle de la temperature est une composante requise pour l'aptitude a fleurir et que la vernalisation est determinante pour le developpement reproductif sous des conditions de jours longs.

Peloquin (1921-2008) AN - 21126712; 11223538 AB - Background Emeritus Campbell-Bascom Professor Stanley J. Peloquin was an internationally renowned plant geneticist and breeder who made exceptional contributions to the quantity, quality and sustainable supply of food for the world from his innovative and extensive scientific contributions. For five decades, Dr Peloquin merged basic research in plant reproduction, cytology, cytogenetics, genetics, potato (Solanum tuberosum) improvement and education at the University of Wisconsin-Madison. Successive advances across these five decades redefined scientific comprehension of reproductive variation, its genetic control, genetic effects, evolutionary impact and utility for breeding. In concert with the International Potato Center (CIP), he and others translated the advances into application, resulting in large benefits on food production worldwide, exemplifying the importance of integrated innovative university research and graduate education to meet domestic and international needs.Scope Dr Peloquin is known to plant breeders, geneticists, international agricultural economists and potato researchers for his enthusiastic and incisive contributions to genetic enhancement of potato using haploids, 2n gametes and wild Solanum species; for his pioneering work on potato cultivation through true seed; and as mentor of a new generation of plant breeders worldwide. The genetic enhancement of potato, the fourth most important food crop worldwide, benefited significantly from expanded germplasm utilization and advanced reproductive genetic knowledge, which he and co-workers, including many former students, systematically transformed into applied breeding methods. His research on plant sexual reproduction included subjects such as haploidization and polyploidization, self- and cross-incompatibility, cytoplasmic male sterility and restorer genes, gametophytic/sporophytic heterozygosity and male fertility, as well as endosperm dosages and seed development. By defining methods of half-tetrad analysis and new cytological techniques, he elucidated modes, mechanisms and genetic controls and effects of 2n gametes in Solanum. Ramifications extend to many other crops and plants, in both basic and applied sciences.Achievements Based upon a foundation of genetics, cytogenetics and plant reproductive biology, Dr Peloquin and co-workers developed methods to use 2n gametes and haploids for breeding, and used them to move genes for important horticultural traits from wild tuber-bearing Solanum species to cultivated potato for the betterment of agriculture. The resulting potato germplasm included combinations of yield, adaptation, quality and disease resistance traits that were previously unavailable. This elite plant germplasm was utilized and distributed to 85 countries by the CIP, because it not only increased potato yields and quality, it also broadened the adaptation of potato to lowland tropical regions, where humanity has benefited from this addition to their food supply.

Little is known about the biology or ecology of A. epos when it utilizes GWSS eggs as a host. Here, we report the results of laboratory studies that describe the host age preference for oviposition, longevity of A. epos adults provided with different food sources, and developmental rates at six different constant temperature regimes. Anagrus epos is a gregarious parasitoid in GWSS eggs with up to 14 adults emerging from each GWSS egg. In choice and no-choice tests for oviposition, A. epos females successfully parasitized all developmental ages of GWSS eggs (1-8 days old). In choice tests, parasitism rates were significantly higher in 1-, 3-, 4-, and 5-day-old GWSS eggs than in 2-, 6-, 7-, and 8-day-old eggs. If provided with honey and water, honey only, water only, or no food or water, A. epos females lived on average 8.2, 4.7, 2.6, and 1.6 days, respectively. Anagrus epos required 294.1 degree-days above a lower temperature threshold of 12.4 C to develop from egg to adult (eclosion). Our results provide baseline information useful in the development of an efficient parasitoid mass rearing program for A. epos release and evaluation in California.

Widespread cultivation of transgenic crops has received considerable attention. Impacts of glyphosate on rhizosphere microorganisms and activities are reviewed based on published and new data from long-term field projects documenting effects of glyphosate applied to GR soybean and maize. Field studies conducted in Missouri, U.S.A. during 1997-2007 assessed effects of glyphosate applied to GR soybean and maize on root colonization and soil populations of Fusarium and selected rhizosphere bacteria. Frequency of root-colonizing Fusarium increased significantly after glyphosate application during growing seasons in each year at all sites. Roots of GR soybean and maize treated with glyphosate were heavily colonized by Fusarium compared to non-GR or GR cultivars not treated with glyphosate. Microbial groups and functions affected by glyphosate included Mn transformation and plant availability; phytopathogen-antagonistic bacterial interactions; and reduction in nodulation. Root-exuded glyphosate may serve as a nutrient source for fungi and stimulate propagule germination. The specific microbial indicator groups and processes were sensitive to impacts of GR crops and are part of an evolving framework in developing polyphasic microbial analyses for complete assessment of GR technology that is more reliable than single techniques or general microbial assays.

Three reference oxbow lakes were located in the White River National Wildlife Refuge (WRNWR), Arkansas and two impaired lakes, according to the US Environmental Agency Sect. 303 (d) Clean Water Act, were located in Mississippi. Surface sediment (top 5cm) was collected at three sites within each lake and analyzed for 17 current and historic-use pesticides and metabolites. Chronic 28-day H. azteca sediment bioassays and pesticide body residue analyses were completed to determine the degree of biological responses and bioavailability. The greatest number of detectable pesticides in WRNWR and 303 (d) sediment samples was 9 and 12, respectively, with historic-use pesticide metabolite, p,p'-DDE [1,1-dichloro-2,2-bis(p-chlorophenyl)ethylene] ubiquitous. No significant (p>0.05) differences in animal survival were observed among sites. Animal growth was significantly (p<0.05) less at only one site in a 303 (d)-listed lake (Macon Lake). Only six pesticides were observed in H. azteca with current-use pesticides detected at three sites; historic-use pesticides and metabolites detected at 11 sites. Animal body residues of a historic-use pesticide (dieldrin) and metabolite (p,p'-DDE) were associated with observed growth responses. Results show limited current-use pesticide contamination of sediments and H. azteca body tissues during autumn and that historic-use pesticides and metabolites are the primary contributors to observed biological responses.

These pyrodiesel samples were compared with soy biodiesel (BD) samples. All these three biofuels (PD, SPD and BD) and their blends with high sulfur (HSD) and low sulfur (LSD) diesel fuels were evaluated by measuring a number of fuel properties, such as oxidative stability, low-temperature performance, acid value and corrosion properties. Compared to BD blends, PD and SPD and their blends were found to have better oxidative stability, though inferior acid values. SPD and its blends have better flow performance at low-temperature compared to BD and PD blends. All the biofuels and their blends met the copper corrosion requirement prescribed by US and European standard. Based on the results reported here, pyrodiesels from these two-different feedstocks have potential and will require some upgrading or change in pyrolysis conditions, if they are to be used as fuel blending component.

Currently, DDGS is used as livestock feed, thereby replacing some corn components in animal diets. As the industry continues to grow, there will be an increased need to find additional uses for DDGS. Physical and chemical properties of coproduct streams are becoming increasingly investigated, as these characteristics affect many aspects of utilization, such as target species, optimal dietary substitution rates, transportation, flowability, and behavior during storage. Potential avenues for future use of DDGS may include value-added feed, food, and industrial products. Additionally, much interest lies in extracting oil from DDGS to produce bio diesel and other products. If oil is extracted from DDGS, the resulting chemical and physical properties of the remaining constituents may be substantially altered. The objective of this study was to quantify, using standard laboratory methods, physical and chemical property values for low-oil DDGS. The extracted DDGS exhibited water activity, thermal properties, bulk density, and angle of repose values similar to unmodified DDGS. Color values were substantially lighter, however. Additionally, fat levels (2.7% db) were much lower, while protein (34.0% db) and fiber (8.4% db) were higher than traditional DDGS. Results from this study will be valuable to ethanol manufacturers and livestock producers alike, as more uses for ethanol coproducts are implemented. Thus more value can be extracted from the humble kernel of corn.

Accordingly, cost-share programs have been established to promote winter cover crops for water quality on farms throughout the Chesapeake Bay watershed. However, current estimates of cover crop nutrient uptake are largely calculated from plot-scale studies extrapolated to watershed-scale based solely on enrollment acreage. Remote sensing provides a tool for rapid estimation of cover crop biomass production on working farms throughout the landscape. This project combined cost-share program enrollment data with satellite imagery and on-farm sampling to evaluate cover crop N uptake on 136 fields within the Choptank River watershed, on Maryland's eastern shore. The Normalized Difference Vegetation Index was a successful predictor of aboveground biomass for fields with >210 kg ha super(-1) (>187 lb ac super(-1)) of vegetation (corresponding to 4.2 kg ha super(-1) [3.7 lb ac super(-1)] of plant N), below which the background reflectance of soils and crop residues obstructed the cover crop signal. Cover crops planted in the two weeks prior to the regional average first frost date (October 15) exhibited average fall aboveground N uptake rates of 18, 13, and 5 kg ha super(-1) (16, 12, 4 lb ac super(-1)) for rye, barley, and wheat, respectively, corresponding to 1,260,725, and 311 kg ha super(-1) (1,124,647,277 lb ac super(-1)) of aboveground biomass, with associated cost-share implementation costs of $5.49, $7.60, and $19.77 kg super(-1) N ($2.50, $3.46, and $8.99 lb super(-1) N). Cover crops planted after October 15 exhibited significantly reduced biomass and nutrient uptake, with associated program costs of $15.44 to $20.59 kg super(-1) N ($7.02 to $9.36 lb super(-1) N).Agronomic factors influencing cover crop performance included species, planting date, planting method, and previous crop. Field sampling locations with >1,000 kg ha super(-1) (>890 lb ac super(-1)) of springtime cover crop biomass exhibited greatly reduced soil nitrate (<3 mg kg super(-1) [<3 ppm]) in comparison to fields with low cover crop biomass (up to 14 mg kg super(-1) soil nitrate), indicating a target biomass threshold for maximum water quality impact. Additional sampling years will be necessary to account for cover crop response to climate variability. Combining remote sensing with farm program data can provide important information to scientists and regulators working to improve conservation programs. Results can be used to more effectively utilize scarce conservation resources and increase water quality protection.

Two channelized and two natural headwater streams located in Upper Big Walnut Creek (UBWC) watershed in Ohio, USA, were instrumented to facilitate measurement, characterization and comparison of hydrology to the accepted paradigm for headwater hydrology. Data were collected at 10-min intervals from 1 January 2005 to 31 December 2006. Differences in flow magnitudes (average, low and high) were generally greater (P < 0.05) in the channelized streams. Frequency of zero discharge and out-of-bank discharge was significantly greater in the natural streams. Zero discharge occurred in summer and out-of-bank flows occurred in winter. Rate of change variables indicated that channelized streams respond more quickly to rainfall, have significantly greater peak flows, and have slower recession times. In contrast, natural streams tend to be more "flashy". The findings were generally consistent with the accepted paradigm for headwater hydrology and attributed to stream type, presence of subsurface drainage, potential connection to groundwater, and differences in riparian vegetation. The design and installation of management practices that influence hydrology should consider the potential impacts of altering stream hydrology. Management practices such as water-table management have the potential and show promise in altering the hydrology of channelized streams to resemble the hydrology of natural streams.

Plant symptoms also resembled those caused by "Candidatus Liberibacter solanacearum" infection. Affected plants showed an overall chlorosis, severe stunting, leaf cupping, purple discoloration of veins, excessive branching of axillary shoots, and leaf scorching. Symptom incidence ranged from 18 to 40%. To investigate whether liberibacter is associated with permanent yellowing disease of tomato in Mexico, eight symptomatic and five asymptomatic tomato plants were collected from two fields in La Cruz de Elota and Culiacan, Sinaloa. Total DNA was extracted from the top whole leaf tissue of symptomatic and asymptomatic plants with cetyl-trimethylammoniumbromide (CTAB) buffer. DNA samples were tested by PCR using primer pairs OA2/OI2c and CL514F/CL514R, which amplify a sequence from the 16S rDNA and rplJ and rplL ribosomal protein genes, respectively, of "Ca. L. solanacearum". The DNA samples were also tested for phytoplasmas with nested PCR using universal primer pairs P1/P7 and fU5/rU3. DNA from five and four symptomatic plants yielded the expected 1,168-bp 16S rDNA and 669-bp rpU/rplL amplicons, respectively, indicating the presence of liberibacter. Extracts from asymptomatic plants yielded no products with these primers. Amplicons generated from three symptomatic plants with each primer pair were cloned into pCRII-TOPO plasmid vectors (Invitrogen, Carlsbad, CA) and three clones of each of these amplicons were subsequently sequenced in both directions (ACGT, Inc., Wheeling, IL). BLAST analysis of the 16S rDNA consensus sequence (GenBank Accession No. FJ957897) showed 100% identity to 16S rDNA sequences of "Ca. L. solanacearum" amplified from S. betaceum (EU935004) and S. lycopersicum (EU834130) from New Zealand, and "Ca. L. psyllaurous" from potato psyllids (EU812559). The rplJ/rplL consensus sequence (GenBank Accession No. FJ957895) was 100% identical to the analogous rplJ and rplL "Ca. L. solanacearum" ribosomal protein gene sequence amplified from S. lycopersicum (EU834131) from New Zealand and 'Ca. Liberibacter' sp. sequence amplified from zebra chip-infected potatoes from Lancaster, CA (FJ498803). No phytoplasmas were detected in the symptomatic tomato plants. To our knowledge, this is the first report of "Ca. L. solanacearum" associated with tomatoes in Mexico. In 2008, this bacterium was detected in glasshouse tomatoes in New Zealand and caused millions of dollars in losses to the commercial glasshouse tomato industry.

Symptoms appeared -6 weeks after psyllids were observed and were generally restricted to the top half of the plant. Leaf cuttings from beefsteak tomatoes cv. Quest were immediately placed in RNAlater (Applied Biosystems, Austin, TX). Samples from symptomatic and asymptomatic plants were collected in September and December of 2002. At each date, leaves were sampled from multiple plants and placed in separate RNAlater bottles. September samples exhibited initial "psyllid yellows" symptoms and December samples exhibited severe symptoms. Samples remained at 4C in RNAlater for 6 years until recent findings suggested that a new species of bacteria, named either "Candidatus Liberibacter psyllaurous" or "Ca. L. solanacearum", may be the causal agent of "psyllid yellows". The Qiagen (Valencia, CA) DNeasy Plant Kit and recommended protocols were used for four separate DNA isolations from each of the four tomato samples that had previously remained unopened. Five PCR primer pairs designed to amplify three distinct genetic regions within the "Ca L. psyllaurous" rrn operon (16S rRNA, 16S-23S rRNA intergenic region, and 23S rRNA) were used and one primer pair specific to the tomato DNA (18S rRNA gene) that successfully amplified from all samples was used as a positive control. Bacterial primers included one pair designed specifically for 16S rRNA sequences of 'Ca. L. asiaticus', 'americanus', and 'africanus' species (USHRL-CL1) and four sets, Lp-1 through Lp-4, previously described that amplify nonoverlapping regions of the 16S-23S rRNA operon. The USHRL-CL1 primers (USHRL-CL1f: 5'-CTTACCAGCCCTTGACAT GTATAGGA-3', and USHRL-CL1r: 5'-TCCCTATAAAGTACCCAACA TCTAGGTAAA-3') amplify a 195-bp fragment from bp 895 to 1,089 of the 'Ca. Liberibacter' sp. 16S rRNA Genbank Accession No. L22532. Only samples from severe symptomatic plants collected in December 2002 yielded amplicons that were purified and sequenced (Genbank: USHRL-CL1, FJ871062; Lp-1, FJ871058; Lp-2, FJ871059; Lp-3, FJ871060; Lp-4, FJ871061). For each bacterial primer pair, the fragment amplified was highly homologous (98 to 100% identity) to "Ca. L. psyllaurous" rRNA gene/intergenic space sequences. The 16S rRNA coding region was identical to two GenBank 'Ca. Liberibacter' sp. entries: EU921627 and EU921626 from B. cockerelli samples collected in Dalhart, TX and zebra chip potato samples from Garden City, KS, respectively; however, the whole 2,500 bp amplified and sequenced from our sample contained 11 to 14 polymorphisms when compared to nine "Ca. L. psyllaurous" sequences. Our results clearly indicate that "Ca. L. psyllaurous" isolates were associated with tomato "psyllid yellows" symptoms in Colorado as early as 2002 and significant sequence variation exists within the 16S/23S rRNA intergenic region and 23S rRNA coding region to allow analysis of genetic diversity among "Ca. L. psyllaurous" isolates.

The objective of this study was to monitor the infection and development of P. longicolla on vegetative and reproductive tissues of six cultivars and to determine the relationship between this infection and subsequent seed infection and seed germination. Cultivars were grown for 3 years (2002 to 2004) without irrigation or with irrigation applied at pre- plus post-flowering or at postflowering growth stages. P. longicolla was isolated most frequently from leaf, stem, pod, root, and seed. Diaporthe phaseolorum and three unidentified Phomopsis sp. were also isolated. Diaporthe aspalathi, which previously has not been reported on soybean, was also recovered from leaf samples. These isolates, however, were recovered very infrequently. Recovery of P. longicolla from roots was much lower than from leaves, stems, and pods in all years and irrigation environments. The recovery of P. longicolla from seed was affected by irrigation environments. Seed from irrigated plots had more P. longicolla than that from nonirri-gated plots. Isolation of P. longicolla from seed was negatively correlated with percentage of seed germination in irrigated environments but not in the nonirrigated environment. Pod infection was correlated with seed infection in all three irrigation environments. Even though infection of leaves and stems increased with increasing moisture availability, such infection did not consistently correlate with seed infection. Seed germination and seed infection were negatively correlated with percent hard seed. This study provided the first demonstration of the seasonal progression of P. longicolla on soybean cultivars grown under three irrigation environments.

There has been no definitive demonstration of the existence of pathotypes for stem rust or other rusts of perennial ryegrass, although experiments with crown rust (Puccinia coronata) of this host are strongly suggestive of pathotype specificity. We made single-pustule isolates of P. graminis subsp. graminicola, and applied them individually to a set of genetically diverse, clonally propagated individuals of L. perenne. There were clear examples of different patterns of virulence among isolates across the different plant clones, including qualitative and quantitative differences in resistance. These data demonstrate the existence of pathotype specificity in stem rust of L. perenne, information which will be useful in breeding for disease resistance.

The only obvious visual difference between them was that one was stagnant and the water was brown in colour (Farm 1), and the other was circulated and the water was red in colour because of the presence of PSB that contained carotenoid pigments (Farm 2). Both wastewaters were sampled monthly for 3 months and assayed for PSB and extractable carotenoid pigments (ECP). After this point, circulators were placed in the wastewater lagoon on Farm 1, and samples were taken monthly for 9 months and assayed for PSB and ECP. Before the installation of circulators, no PSB-like 16S rRNA sequences or ECP were observed in the wastewater from Farm 1; however, both were observed in the wastewater from Farm 2. After the installation of circulators, statistically greater levels of PSB and extractable carotenoid pigments were observed in the wastewater from Farm 1.Conclusions: Circulation enhances the growth of PSB in dairy wastewater.Significance and Impact of this Study: Because PSB utilize H2S and volatile organic acids (VOA) as an electron source for photosynthesis, and VOA and alcohols as a carbon source for growth, the increase in these bacteria should reduce H2S, volatile organic compounds and alcohol emissions from the lagoons, enhancing the air quality in dairy farming areas.

The objective of this study was to evaluate 29 genotypes for drought tolerance under drought stress (DS) and reduced stress treatments in Juana Diaz, Puerto Rico. The use of DS and reduced stress treatments facilitated the identification of drought tolerant germplasm that also had good yield potential under more optimal conditions. Based on the results of seed yield under DS and reduced stress conditions, and DS indices, including the geometric mean (GM), stress tolerance index (STI) and percent yield reduction (YR), genotypes were identified with greater yield potential under the tested environment. Based on average GM over the 2 years, the superior common bean genotypes identified were SEA 5, G 21212, A 686, SEN 21 and SER 21. These genotypes performed well in both years and under both treatment conditions and thus may serve as parents for DS improvement and genetic analysis.

These conditions simulate those associated with summer mortality syndrome, a poorly understood cause of massive mortalities in cultured Pacific oysters in North America, Asia and Europe. Using 32 AFLP primer pairs, we identified 92 transcript-derived fragments that are qualitatively differentially expressed. We then cloned and sequenced 14 of these fragments, designed fragment-specific primers and quantified their transcription patterns using RT-qPCR. Most of the differences in transcription patterns between stress-tolerant and stress-sensitive families were evident before bacterial exposure, and genes that responded to bacterial exposure did so in parallel between stress-sensitive and stress-tolerant families. blast searches of sequence databases revealed that these fragments represent genes involved in immune response as well as genes related to metabolic processes. Our data support the hypothesis that family level differences in resistance to stress in Pacific oysters are largely attributable to constitutive differences in gene transcription or 'general vigour' that are detectable before and maintained after infection, rather than being due to induced responses at the transcriptome level.

Calpastatin is a likely positional candidate gene in this region because of its inhibitory role in the calpain system that is involved in postmortem tenderization. Novel single nucleotide polymorphisms (SNP) in calpastatin were identified and used to genotype a population (n = 1042) of Duroc-Landrace-Yorkshire swine for association with longissimus lumborum slice shear force (SSF) measured at days 7 and 14 postmortem. Three genetic markers residing in the calpastatin gene were significantly associated with SSF (P < 0.0005). Haplotypes constructed from markers in the calpastatin gene were significantly associated with SSF (F-ratio = 3.93; P-value = 0.002). The levels of normalized mRNA expression of calpastatin in the longissimus lumborum of 162 animals also were evaluated by real-time RT-PCR and were associated with the genotype of the most significant marker for SSF (P < 0.02). This evidence suggests that the causative variation alters expression of calpastatin, thus affecting tenderness. In summary, these data provide evidence of several significant, publicly available SNP markers associated with SSF that may be useful to the swine industry for marker assisted selection of animals that have more tender meat.

The robust nature of the pyrolysis technology, which allows considerable flexibility in both the type and quality of the biomass feedstock, combined with a distributed network of small pyrolysis plants, would be compatible with existing agriculture and forestry infrastructure. Bio-oil can be used as a fuel in existing industrial boilers. Biochar can be used with existing infrastructure as a replacement for pulverized coal; however, use of biochar as a soil amendment results in significant environmental and agronomic benefits. Soil application of biochar is a means of sequestering large amounts of C and may have other greenhouse gas benefits. Preliminary reports of the impact of soil biochar applications on crop yields indicate that biochar quality is very important. Biochar is an effective adsorbent for both nutrients and organic contaminants, hence the presence of biochar in soils has been shown to improve water quality in column leaching and field lysimeters studies and it is anticipated to do the same for agricultural watersheds. The pyrolysis platform for producing bio-oil and biochar from biomass appears to be a practical, effective, and environmentally sustainable means of producing large quantities of renewable bioenergy while simultaneously reducing emissions of greenhouse gases. At the present time, the pyrolysis platform is economically marginal because markets for bio-oil and biochar are highly competitive. However, if the USA adopts a program for controlling greenhouse gases, the pyrolysis platform would be highly competitive. Published in 2009 by John Wiley & Sons, Ltd.

We present results using standard and real-time PCR to show cross-amplification of Bacteroides 16S rRNA gene molecular assays targeting human fecal pollution with fecal DNA from freshwater fish species. All except one of the presumptively human-specific assays amplified fecal DNA from at least one fish species, and one real-time PCR assay amplified DNA from all fish species tested. Sequencing of PCR amplicons generated from fish fecal DNA using primers from the real-time assay revealed no mismatches to the human-specific probe sequences, but the nucleotide sequences of clones from fish fecal samples differed markedly from those of human feces, suggesting that the fish-related bacteria may be different strains. Our results strongly demonstrate the potential for cross-amplification of human-specific PCR assays with fish feces, and may call into question the results of studies in which these Bacteroides-specific molecular markers are used to quantify human fecal contamination in waters where fish contribute to fecal inputs.

Seeds were planted in prairie soil and watered at 1, 2, 4, or 7 d intervals (I). Seed germination peaked at I = 4 d whereas leaf growth in grasses and forbs, and final biomass in grasses peaked at I = 7 d, suggesting that growth and biomass were favored at greater soil moisture variability than seed germination. Biomass responses to I were stronger than the germination responses, suggesting that soil moisture variability more strongly influenced post germination growth. Individual species responses to I fell into three groups; those with responses to I for: (1) seed germination and seedling survival, (2) biomass, or (3) both germination and biomass production. These species groups may be more useful than life form (i.e., grass/forb) for understanding seed germination and seedling dynamics in grasslands during periods of soil moisture variability. Seed germination and early growth may assume more importance in grassland plant community dynamics under more variable precipitation patterns.

However, the impacts of pyrolysis biochar on the soil system need to be assessed before initiating large scale biochar applications to agricultural fields. We compared CO sub(2) respiration, nitrous oxide (N sub(2)O) production, methane (CH sub(4)) oxidation and herbicide retention and transformation through laboratory incubations at field capacity in a Minnesota soil (Waukegan silt loam) with and without added biochar. CO sub(2) originating from the biochar needs to be subtracted from the soil-biochar combination in order to elucidate the impact of biochar on soil respiration. After this correction, biochar amendments reduced CO sub(2) production for all amendment levels tested (2, 5, 10, 20, 40 and 60% w/w; corresponding to 24-720tha super(-) super(1) field application rates). In addition, biochar additions suppressed N sub(2)O production at all levels. However, these reductions were only significant at biochar amendment levels >20% w/w. Biochar additions also significantly suppressed ambient CH sub(4) oxidation at all levels compared to unamended soil. The addition of biochar (5% w/w) to soil increased the sorption of atrazine and acetochlor compared to non-amended soils, resulting in decreased dissipation rates of these herbicides. The recalcitrance of the biochar suggests that it could be a viable carbon sequestration strategy, and might provide substantial net greenhouse gas benefits if the reductions in N sub(2)O production are lasting.

The purpose of this study is to evaluate empirically the dynamic interactions between primary and scrap metal prices through multivariate time series methods. In addition, the study expands the investigation at the level of volatility transmission, which has not been previously examined. The metal prices utilized are for copper, lead, and zinc for the period 1984-2001. The paper demonstrates differing long run and short run links. Scrap prices do not improve the long run interpretation of primary prices, but information flows from the scrap to the primary markets exist in the short run. Additionally, the copper and lead markets exhibit bidirectional information flows in terms of volatility transmission. The analysis provides valuable insight into the interactions of the primary and scrap metal sectors which can be used to improve forecasting and planning.

Although laboratory-scale studies have shown that extractable concentrations of these compounds decrease over time within treated and untreated manures and soils, there is relatively little information from farm-scale experiments. The objective of this study was to determine the effect of different levels of management on manure pile temperature profiles and on the fate of OTC and CTC in manure from therapeutically treated calves. Four treatments were designed to span a range of management options - from simply piling up the manure to amending it with straw to increase aeration and adding insulating layers of straw. Replicate samples of antibiotic-containing calf manure were held at ambient temperature or placed in three locations within replicate 3 m[super]3 piles of beef manure. During the 28-day incubation period, concentrations of buffer-extractable OTC and CTC/ECTC (the summed concentrations of CTC and its epimer 4-epi-chlortetracycline (ECTC)) in manure samples incubated at ambient temperature (11-24 [degree]C) decreased 75% (from 18 to 4.6 mg kg[super]-1 dry weight (DW)) and 90% (from 192 to 16 mg kg[super]-1 DW), respectively. Concentrations of the CTC metabolite iso-chlortetracycline (ICTC) decreased 90% (from 37 to 3 mg kg[super]-1 DW). OTC and CTC/ECTC concentrations in samples incubated for 28 days within a non-amended manure pile decreased 91% and >99%, respectively. During that period, the manure pile temperature ranged from 36 [degree]C to 45 [degree]C. Manure piles insulated with a blanket of straw and/or amended with straw (3:1, v/v) attained temperatures up to 70 [degree]C and contained very low levels of OTC, CTC/ECTC, and ICTC (ranging from <0.1 to 0.4 mg kg[super]-1 DW) after 28 days.

One problem that has hindered adoption of automated technologies has been the inability to image the complete surface of an individual fruit. A particular problem is that both the stem and calyx are concave structures. The goal of this project was to examine tradeoffs for using multiple mirrors to image the surface of apples. For testing, individual apples were suspended using two thin wires, mirrors were placed around an apple, and movies were captured at 90 images per sec. Apples were rotated in all dimensions to examine the efficacy of different mirror configurations. It was determined that specific configurations of two, four, or six parabolic concave mirrors could image an entire surface. A configuration using two mirrors and multiple images acquired as apples roll by was also found to be viable.

Yet, previous studies, although rather limited, have not established this relationship. In this study, six ground corn samples and their resulting DDGS were analyzed for particle size distribution (PSD), using a series of six selected US standard sieves: Nos. 8, 12, 18, 35, 60, and 100, and a pan. The original sample and sieve sized fractions were measured for contents of moisture, protein, oil, ash and starch, and surface color. Total carbohydrate (CHO) and total non-starch CHO were also calculated. Results show that the geometric mean diameter (d[sub]gw) of particles varied with individual corn and DDGS samples, and that d[sub]gw of DDGS was larger than that of corn (0.696 vs. 0.479 mm, average values), indicating that during conversion of corn to DDGS, certain particles became enlarged. For d[sub]gw and mass frequency of individual particle size classes, the relationship between ground corn and DDGS varied, but PSD of the whole sample was well correlated between them (r = 0.807). Upon conversion from corn to DDGS, on an average, protein was concentrated 3.59 times; oil, 3.40 times; ash, 3.32 times; and total non-starch CHO, 2.89 times. There were some positive correlations in contents of protein and non-starch CHO and in L value between corn and DDGS. Yet, variations in nutrients and color attributes were larger in DDGS than in corn. For either corn or DDGS, these variations were larger in sieved fractions than in the whole fraction. Raw material, processing method and addition of yeasts are among major factors considered for causing larger variations in these attributes among DDGS. The study partially supports the common belief by processors that quality attributes of corn affect those of DDGS.

PCR coupled with a chromosomal gene-walking method was used to clone and subsequently sequence the contiguous phaC (1,068bps) and phaE (1,065bps) genes of A.vinosum ATCC 35206. BLASTP search of protein databases showed that the gene-products of phaC and phaE are different (<66% identities) from the previously reported class III PHASs such as those of A.vinosum DSM180. Domain analysis revealed the presence of a conserved a/b-hydrolase fold in PhaC, the putative gene-product of phaC. Upon electroporation of a poly(hydroxybutanoate) (PHB)-negative mutant of Ralstonia eutropha PHB super(-)4 with a shuttle plasmid pBHR1 containing the newly cloned phaC and phaE genes, the bacteria resumed the synthesis of PHB, albeit at a low level (4-5% of the cell dry wt) due to kanamycin selection pressure. We further showed that the recombinant strain grown in kanamycin-containing culture medium synthesized a blend of PHA that also contains a high content of 3-hydroxyoctanoate and 3-hydroxydecanoate as its repeat-unit monomers. Genomic analysis suggested the existence of two PHA synthase genes in R.eutropha. The results of this study not only make available a phylogenetically diverse type III phaC and phaE genes, but also confirm through kanamycin selection pressure the existence of multiple PHA biosynthesis systems in R.eutropha.

In the US Midwest, increasing baseflow has been more attributed to increased annual cropping than climate change. The agricultural changes have led to increased fertilizer use and nutrient losses, contributing to Gulf of Mexico hypoxia. In a 25-yr, small-watershed experiment in Iowa, when annual hydrologic budgets were accrued between droughts, a coupled water-energy budget (ecohydrologic) analysis showed effects of tillage and climate on hydrology could be distinguished. The fraction of PPT discharged increased with conservation tillage and time. However, unsatisfied evaporative demand (PET - Hargreaves method) increased under conservation tillage, but decreased with time. A conceptual model was developed and a similar analysis conducted on long-term (>1920s) records from four large, agricultural Midwest watersheds underlain by fine-grained tills. At least three of four watersheds showed decreases in PET, and increases in PPT, discharge, baseflow and PPT:PET ratios (p<0.10). An analysis of covariance showed the fraction of precipitation discharged increased, while unsatisfied evaporative demand decreased with time among the four watersheds (p<0.001). Within watersheds, agricultural changes were associated with ecohydrologic shifts that affected timing and significance, but not direction, of these trends. Thus, an ecohydrologic concept derived from small-watershed research, when regionally applied, suggests climate change has increased discharge from Midwest watersheds, especially since the 1970s. By inference, climate change has increased susceptibility of nutrients to water transport, exacerbating Gulf of Mexico hypoxia. evapotranspiration JF - Journal of Hydrology (Amsterdam) AU - Tomer, MD AU - Schilling, KE AD - National Soil Tilth Laboratory, 2110 University Blvd., Ames, Iowa 50011, USA mark.tomer@ars.usda.gov Y1 - 2009/09/30/ PY - 2009 DA - 2009 Sep 30 SP - 24 EP - 33 PB - Elsevier Science, P.O.

Gilg (Gentianaceae, Helieae) is among the largest woody genera of tropical gentians, with most of its species occurring in the wet mountainous forests of the Andes. Phylogenetic and dispersal-vicariance analyses (DIVA) of 57 of the 105 currently recognized species in the genus, using two data sets from nuclear DNA (ITS and 5S-NTS sequences) and morphology, show a single origin of the Andean species from an ancestral distribution that includes southeastern Brazil. Within the Andes, species divide into two major clades: (1) northern species from the cordilleras of northern Ecuador, Colombia, and Venezuela; and (2) southern species of the Andean Amotape-Huancabamba Zone in Ecuador and Peru, as well as the Andes of central and southern Peru and Bolivia. The Amotape-Huancabamba Zone is supported as the ancestral area for Macrocarpaea within the Andes. There are repeated speciation patterns within the Andes, and three Mesoamerican species derive from the northern clade, as is the single sampled species from the Guayana Shield. The position of the subclade of the three Caribbean species is less certain, but it currently nests among Andean species. An Atlantic coastal Brazilian clade is placed as sister group to all other Macrocarpaea, providing further support for an ancestral refuge in southeastern Brazil for the Helieae. The biogeographic analysis showed that local speciation is more common than long-distance dispersal, and allopatric speciation is more common than sympatric speciation. Using detailed, georeferenced herbarium collection data, patterns in environmental characteristics between clades and sister species were analyzed with Spatial Evolutionary and Ecological Vicariance Analysis (SEEVA), utilizing geographic information system (GIS) and statistical methods. Sister clades and taxa were evaluated for statistical significance in variables such as annual rainfall and temperature, elevation, temperature and rainfall seasonality, geological bedrock age, and soil type to evaluate ecological vicariance between sister groups. The results indicate that there are no general patterns for each variable, but that there are many significant divergences in ecological niches between both larger sister groups and sister species, and ecological niche conservation was also observed when subsequent nodes in the phylogeny were compared.

These measurements provide a unique opportunity to test current models of atmospheric RO sub(x) (OH + HO sub(2) + RO sub(2)) photochemistry under polluted conditions. A zero-dimensional box model based on the Regional Atmospheric Chemical Mechanism (RACM) was constrained by 10-min averages of 24 J-values and the concentrations of 97 chemical species. Several issues related to the RO sub(x) chemistry under polluted conditions are highlighted in this study: (i) Measured concentrations of both OH and HO sub(2) were underpredicted during morning hours on a median campaign basis, suggesting a significant source of radicals is missing from current atmospheric models under polluted conditions, consistent with previous urban field campaigns. (ii) The model-predicted HO sub(2)/OH ratios underestimate the measurements for NO mixing ratios higher than 5 ppb, also consistent with previous urban field campaigns. This suggests that under high NO sub(x) conditions, the HO sub(2) to OH propagation rate may be overestimated by the model or a process converting OH into HO sub(2) may be missing from the chemical mechanism. On a daily basis (08:40 a.m.-06:40 p.m.), an analysis of the radical budget indicates that HONO photolysis, HCHO photolysis, O sub(3)-alkene reactions and dicarbonyls photolysis are the main radical sources. O sub(3) photolysis contributes to less than 6% of the total radical production.

Its induction is highly affected by the types of cytokines and the infectious agents present. In the current study, NO production was evaluated after in vitro infection of unfractionated peripheral blood mononuclear cells (PBMCs) with Mycobacterium avium subsp. paratuberculosis (MAP) after 8h, 3 and 6 days of culture for cows in different stages of disease. In addition, the effects of in vitro exposure to inhibitory cytokines such as interleukin-10 (IL-10) and transforming growth factor b (TGF-b) as well as the pro-inflammatory cytokine IFN-g were correlated with the level of NO production. Nitric oxide production was consistently higher in cell cultures from subclinically infected animals at all time points. An upregulation of NO production was demonstrated in unfractionated cell cultures from healthy control cows after exposure to MAP infection as compared to noninfected cell cultures. A similar increase in NO due to the addition of MAP to cell cultures was also noted for clinically infected cows. NO level among subclinically infected cattle was greater at all time points tested and was further boosted with the combination of both in vitro MAP infection and IFN-g stimulation. Alternatively, nonspecific stimulation with LPS from Escherichia coli O111:B4-W resulted in an upregulation of NO production in all infected groups at 3 and 6 days after in vitro infection. Finally, the in vitro exposure to inhibitory cytokines such as IL-10 and TGF-b prior to MAP infection or LPS stimulation resulted in the downregulation of this inflammatory mediator (NO) in all experimental groups at all time points. In summary, a higher level of NO production was associated with cows in the subclinical stage of MAP infection. As well, the results demonstrated an increase in NO production upon infection with MAP and in the presence of exogenous IFN-g. Finally, the results suggest an important role of IL-10 and TGF-b on the profile of NO production which may explain the low NO production in MAP clinically infected cows.

14129644 AB - The brown marmorated stink bug, Halyomorpha halys (Staal) (Pentatomidae), is a newly invasive species in the eastern U. S. that is rapidly expanding its range from the original point of establishment in Allentown, Pennsylvania. Although an attractant pheromone has yet to be identified for H. halys, in its native Asian range the insect is cross-attracted to the pheromone of another pentatomid Plautia stali Scott whose males produce methyl (E,E,Z)-2,4,6-decatrienoate. Previous tests of methyl 2,4,6-decatrienoate isomers in the U. S. verified that H. halys is highly attracted to methyl (E,E,Z)-2,4,6-decatrienoate, and that the native green stink bug, Acrosternum hilare (Say), also is attracted to this compound. Using traps baited with methyl 2,4,6-decatrienoates and the reported pheromone of A. hilare (trans- and cis(Z)- alpha -bisabolene epoxides), we monitored populations of the brown marmorated and green stink bugs at the Agricultural Research Center, Beltsville, Maryland, for the 2004-2008 growing seasons. Over this time period, the H. halys population rose from being undetectable in 2004 to becoming much more abundantly trapped than the native A. hilare. Furthermore, A. hilare was significantly more attracted to methyl (E,E,Z)-2,4,6-decatrienoate than the blend of bisabolene epoxides reported as its pheromone. Supplemental material online at http:/ / www.fcla.edu/FlaEnt/fe923.htm#InfoLink1Original Abstract: La chiche marron marmol, Halyomorpha halys (Staal) (Pentatomidae), es una nueva especie invasora en el este de Estados Unidos, la cual esta expandiendo su rango de distribution rapidamente desde su punto original de entrada en Allentown, Pennsylvania. Aunque su feromona aun no se ha identificada, este insecto es atraido en su habitat nativo (Asia) por la feromona de otro pentatomido, Plautia stali Scott, cuyos machos producen (E,E,Z)-2,4,6-decatrienoato de metilo. Experimentos previos con distintos isomeros de 2,4,6-decatrienoato de metilo en Estados Unidos demostraron que H. halys es fuertemente atraida por (E,E,Z)-2,4,6-decatrienoato de metilo, y que la chiche verde nativa Acrosternum hilare (Say) es tambien atraida por este compuesto. Usando trampas cebadas con 2,4,6-decatrienoatos y con la feromona reportada para A. hilare (ep*oxidos de (E)- y (Z)- alpha -bisaboleno), realizamos un seguimiento poblacional de ambas especies en la Agricultural Research Center, Beltsville, Maryland, durante las temporadas de crecimiento 2004-2008. En este periode, las poblaciones de H. halys aumentaron desde niveles no detectables en 2004, a valores de capturas sustancialmente mayores que los correspondientes a la especie nativa. Asimismo, A. hilare fue significativamente mes atraida al (E,E,Z)-2,4,6-decatrienoato de metilo que a la mezcla de epoxidos de alpha -bisabolenos, reportados como la feromona de esta especie.

Laboratory trials were conducted to measure the NH sub(3) volatile fraction (undissociated NH sub(3) fraction divided by Henry's law constant) and volatilization flux from buffered ammonium-water solution and dairy cattle manure. Effects of ionic strength, ammoniacal N concentration, temperature and pH of the media, and air velocity over the media were evaluated. As represented in existing models, media type, temperature, and pH were verified to influence the NH sub(3) volatile fraction and mass transfer. Model prediction underestimated the volatile NH sub(3) fraction by 5% in solution trials and 94% in manure trials. This underestimation was attributed to an increase in surface pH created through the emission of carbon dioxide (CO sub(2)). Ammonia emission rate from both the ammonium solution and manure surfaces was affected by temperature and air velocity. A frequently used dairy manure volatilization model predicted NH sub(3) emission rates from manure surfaces more accurately than that from buffered solution with average errors of -16% and +81%, respectively. Temperature significantly affected the difference between predicted and measured rates, with the greatest error at temperatures over 25 degree C. The results imply that further model development is needed to improve the accuracy of predicting NH sub(3) emissions from dairy cattle manure with an emphasis on the measurement and prediction of manure surface pH as affected by CO sub(2) emission.

To determine the potential air quality impacts of these facilities, we measured ammonia (NH sub(3)), methane (CH sub(4)), and nitrous oxide (N sub(2)O) concentrations over the pens, wastewater storage pond, and composting area on a 700-cow open-lot dairy using open-path Fourier transform infrared spectrometry (OP/FTIR). Concentrations were measured for one or two days at each location during January, March, June, and September. Median NH sub(3) concentrations over the pens, storage pond, and composting area ranged from 0.14 to 0.39 ppmv, 0.04 to 0.17 ppmv, and 0.06 to 0.22 ppmv, respectively, with concentrations tending to be lower in January. Average CH sub(4) concentrations over the pens, storage pond, and composting area ranged from 2.07 to 2.80 ppmv, 1.87 to 2.15 ppmv, and 1.71 to 1.76 ppmv, respectively. Average N sub(2)O concentrations ranged from 0.31 to 0.33 ppmv for all areas, which was similar to global background N sub(2)O concentrations. Combined ammonia emissions for the pen and storage pond areas, calculated with a backward Lagrangian stochastic inverse-dispersion technique, were 0.04, 0.25, 0.19, and 0.15 kg NH sub(3) cow super(-1) d super(-1) for January, March, June, and September, respectively, and methane emissions were 0.34, 0.55, 0.21, and 0.20 kg CH sub(4) cow super(-1) d super(-1) for the same months. Assuming this limited monitoring was representative of the entire year, annual emissions from the pens and storage pond were 57 kg NH sub(3) cow super(-1) and 120 kg CH sub(4) cow super(-1). These emission rates were similar to the limited number of comparable studies that have been published. However, more extensive monitoring is needed to better quantify variations in emissions throughout the year and among locations.

Conventional, ground-based lek counts are labor-intensive, expensive, and have several sources of potential error and bias, including the practical limits on number and distribution of leks counted. We tested aerial methods for photographing multiple leks during a single morning. We completed 14 aerial approaches to 6 leks in 2 different years using 2 different airplanes and altitudes. Grouse flushed from leks on 12 approaches when the airplane was within 200-300 m of the lek. In 2 instances, strutting grouse crouched and stayed on the lek. Our highest-resolution images increased our confidence in grouse identification but also decreased field-of-view coverage to the detriment of count accuracy. The methods we tested do not allow sage-grouse to be accurately counted, but the results provide information about sage-grouse responses to low-altitude airplane approaches and about useful image resolutions and fields of view.

Potted wax myrtle and azalea plants were treated with bifenthrin (0.79% AI) at maximum label rate using backpack and electrostatic sprayers and exposed to various treatments that could affect the residual degradation of the applied pesticides. Treatments included leaf aspect, simulated rainfall, shade, and natural sun exposure with the residual effectiveness of leaves examined in tarsal contact Petri dish assays using laboratory-reared Aedes aegypti. There was no significant difference in efficacy between the adaxial (top) or abaxial (bottom) surfaces of electrostatically or backpack-treated leaves. Significant differences existed between application method, plant species, and exposure with most significant effects between weeks 1 and 4. Simulated heavy rainfalls applied 3 times weekly reduced knockdown by leaves treated with electrostatic and backpack methods with reductions seen as soon as 1 wk after treatment. Reductions were seen with both wax myrtle and azalea leaves and after 1, 4, and 24 h contact of mosquitoes to leaves. Placement of plants with full exposure to sunlight also significantly reduced efficacy compared to plants placed in the shade. Differences were observed most often for 4 and 24 h knockdown counts, and significant decreases were seen from week 4 onwards. Clearly factors such as rain and exposure to sun impact degradation of efficacy of bifenthrin-treated vegetation in the field. Degradation of bifenthrin efficacy was slowest in sites protected from rain and sun, which coincide with preferred resting site locations for many mosquito species.

Two conventional and three electrostatic sprayers were used in the study. Usefulness of the sprayers was rated based on penetration of spray into and deposition onto 2 sides of leaves on natural vegetation. Bifenthrin (Talstar(TM) adulticide) was applied at labeled rate, fluorescent dye was added to the tank mix as tracer, and all sprayers applied the dye and insecticide at the same rate. The results indicated that sprayers producing larger droplets produced significantly higher deposition on vegetation in barrier applications than the sprayers producing smaller droplets. Sprayers with higher air velocity at the nozzle discharge proved significantly better for barrier sprays than the sprayers with lower air velocity. Electrostatic sprayers did not show any improvement in deposition on vegetation or in penetration into vegetation over the conventional sprayers. There was no difference in deposition between truck-mounted and backpack sprayers.

Among the table egg sector of the poultry industry, live attenuated strains of MG are commonly used to limit production losses associated with MG-induced disease. These vaccines, however, may be problematic to broiler- and turkey-related industries because of associated virulence; therefore, an understanding of the transmissibility of the live MG vaccines is of particular importance. In the present study, a broiler model addresses the effect of vaccine application route and dosage on the transmission of the MG vaccine FVAX-MG registered to commingled unvaccinated subjects for 7 wk postvaccination. Vaccinations occurred at 2 wk of age via eyedrop or spray application at 1 (4 106 colony-forming units [cfu]), 10-3 (4 103 cfu), or 10-6 (4 cfu) of the manufacturer's recommended dosage, and subsequent transmission to unvaccinated subjects was measured. The serologic response to MG antigen and the presence of MG DNA indicated FVAX-MG transmission only within the 1 FVAX-MG eyedrop treatment. Among no other treatment was transmission of FVAX-MG detected. The results of the present study demonstrate that the dosage and vaccination route may have direct implications on subsequent transmission of FVAX-MG.

Emissions occur from manure surfaces on the barn floor, during storage, and following field application. Process-based modeling with computer simulation is a cost-effective procedure for quantifying and evaluating emissions across diverse production systems. Based upon theoretical principles and associated published information on ammonia emissions, relationships were refined for modeling the dissociation constant, Henry's law constant, and the mass transfer coefficient to improve predictions of ammonia loss from manure surfaces. Inconsistencies found in widely used expressions for the dissociation constant and mass transfer coefficients in ammonia volatilization models from manures are discussed. Refined expressions were developed that relate these parameters to the temperature, pH, and ionic strength of the ammonium-containing material, and the velocity of air flowing over the material. These expressions were tested by comparing predicted ammonia emission rates to values measured in controlled laboratory experiments for buffered ammonium-water solutions and dairy cattle manure. Experimental results compared well to values predicted using these theoretical expressions derived from ammonia volatilization literature. These process-based relationships provide a basis for developing predictive tools that quantify management effects on ammonia emissions from farms and thus assist in the development and evaluation of strategies for reducing emissions.

Riparian vegetation is expected to attenuate drift, but there is little corresponding data. A field study was conducted in the Coast Range west of Corvallis, Oregon, to evaluate the effectiveness of forested riparian buffers. The buffers studied are typical of those used for small and medium fish-bearing streams in western Oregon as mandated by the Oregon Forest Practices Act. A helicopter sprayed two tracers over four transects. Twenty trials were conducted, resulting in over 1400 tracer samples. Results confirm that these vegetative barriers are effective at reducing deposition into streams. Reduction of deposition on artificial foliage samplers placed immediately above the stream surface ranged from 37% to 99% and averaged 92%. Reductions were less clear in stable atmospheric conditions due to low wind speed and highly variable wind directions. Low wind speed conditions are not generally high-drift scenarios, but there is evidence that drift of suspended droplets beyond the barrier, comprising a small fraction of the total mass, increases in stable conditions.

We evaluated the model using ten years (1996-2005) of measured data from a subsurface-drained, corn-soybean agricultural system near Story City, Iowa. Nitrogen fertilizer was applied to plots at low, medium, and high rates (57 to 67 kg N ha super(-1), 114 to 135 kg N ha super(-1), and 172 to 202 kg N ha super(-1), respectively) during corn years, and nitrate (NO sub(3)) losses from subsurface drains under each plot were monitored biweekly for ten years. Average annual simulated and measured NO sub(3) losses in drainage water were 21.9 and 20.1 kg N ha super(-1) for the low N rate, 26.6 and 26.5 kg N ha super(-1) for the medium N rate, and 36.6 and 37.0 kg N ha super(-1) for the high N rate, respectively. The model efficiency statistics for DRAINMOD-N II simulations of annual subsurface drain NO sub(3) losses were 0.89, 0.95, and 0.94 for the low, medium, and high N rates, respectively. For the same experimental dataset, a comparison of DRAINMOD-N II simulations to that of another model that simulates hydrologic and N dynamics of agricultural systems, the RZWQM-DSSAT hybrid model, demonstrated that the two models were most different in their simulations of soybean N fixation, plant N uptake, and net N mineralization. Future field investigations should focus on generating better understandings of these processes. The results suggest that DRAINMOD-N II can reasonably simulate the effects of different corn-year N rates on losses of NO sub(3) through subsurface drainage lines and that simulations of subsurface drainage NO sub(3) losses by DRAINMOD-N II are comparable to that of RZWQM-DSSAT.

In addition, the methods used to incorporate the rainfall data into the simulation model can significantly impact the results. The objectives of this study were to (1) assess the hydrologic impacts of different methods for incorporating spatially variable rainfall input into the Soil and Water Assessment Tool (SWAT) in conjunction with subwatershed delineation level and (2) assess seasonal and spatial uncertainty in hydrologic and water quality simulations of SWAT with respect to rain gauge density. The study uses three different methods to incorporate spatially variable rainfall into the SWAT model and three levels of subwatershed delineation. The impacts of ten different gauge-density scenarios on hydrology and water quality were subsequently evaluated by using the highest gauge-density scenario as a baseline for comparison. Through the centroid method, which is currently used by the AVSWAT-X interface, variations in the representation of measured annual rainfall as model input and corresponding simulated streamflow increased as subwatershed delineation level decreased from high-density to low-density. The rainfall input by the Thiessen averaging method for each subwatershed (Thiessen method) and the inverse-distance-weighted averaging method for the entire watershed (average method) were not sensitive to subwatershed delineation. The impacts of delineation on streamflow were also less with these two methods. The Thiessen method is recommended for SWAT simulation of a watershed with high spatial variability of rainfall. The currently used AVSWAT-X centroid method will also accurately represent spatially variable rainfall if a subwatershed delineation is used that sufficiently incorporates the density of observed rainfall stations. As the number of rain gauges used for the simulation decreased, the uncertainty in the hydrologic and water quality model output increased exponentially. Total phosphorus was most sensitive to the changes in rain gauge density, with an average coefficient of variation of root mean square difference (CV sub(RMSD)) of 0.30 from three watersheds, followed by sediment, total nitrogen, and streamflow, showing CV sub(RMSD) values of 0.24, 0.18, and 0.17, respectively. Seasonal variations in simulated streamflow and water quality were higher during summer and fall seasons compared to spring and winter seasons. These seasonal and temporal variations can be attributed to the rainfall patterns within the watershed.

Samples of 5 g of each variety of rice were placed individually in vials and were analyzed with the electronic nose unit consisting of 32 polymer sensors. The Cyranose-320 was able to differentiate between varieties of rice. The chemical composition of the rice odors for differentiating rice samples needs to be investigated. The optimum parameter settings should be considered during the Cyranose-320 training process especially for multiple samples, which are helpful for obtaining an accurate training model to improve identification capability. Further, it is necessary to investigate the E-nose sensor selection for obtaining better classification accuracy. A reduced number of sensors could potentially shorten the data processing time, and could be used to establish an application procedure and reduce the cost for a specific electronic nose. Further research is needed for developing analytical procedures that adapt the Cyranose-320 as a tool for testing rice quality.

Scientists at the Southern Regional Research Center (SRRC) have previously demonstrated that a thin biodegradable film can be produced from soapstock, an underused byproduct from the vegetable oil industry. After physical and chemical treatments, a thin film was produced from various soapstocks (cottonseed and safflower). Different hydration ratios were tested since the initial soapstock solutions were rather viscous. To examine the potential use of an oilseed-derived lipid film for the extension of shelf life, different types of the oilseed-derived soapstocks were utilized to produce lipid films with different hydration ratios, and containing 0, 5, and 10% of paraffin wax for application on 'Camelot' bell peppers. Control bell peppers lost almost 25% weight per unit surface area (SA) in 78 h when stored under ambient conditions. Cottonseed film-coated peppers, hydrated at 1:4, lost only about 5% moisture per unit SA after 78 h and minimized weight loss by up to 79% compared to the control. However, since a 1:4 hydration ratio remained rather viscous, 1:8 was preferred and these cottonseed films reduced weight loss per unit SA by up to 48% during storage. Safflower-derived soapstock film resulted in the least effective water retention of the films and ratios tested, with roughly 21-25% reduction in weight loss per SA compared to controls. Safflower-derived soapstock was higher in unsaturated fatty acids, which are less efficient to control moisture migration because they are more polar than saturated lipid materials, as contained in cottonseed-derived materials. Addition of wax to the cottonseed-derived films decreased water loss slightly, similar to previous reports in the literature. An ANOVA supported the conclusion that the oilseed-derived lipid films significantly reduced moisture loss across the produce epidermis. To avoid potential allergenicity concerns in cottonseed soapstock, additional cleanup steps and tests with commonly used edible coating additives would be required before attaining food grade status.

Moench) Lines with Reduced Lignin Contents AN - 746047948; 11768923 AB - Lignin is known to impede conversion of lignocellulose into ethanol. In this study, forage sorghum plants carrying brown midrib (bmr) mutations, which reduce lignin contents, were evaluated as bioenergy feedstocks. The near-isogenic lines evaluated were: wild type, bmr-6, bmr-12, and bmr-6 bmr-12 double mutant. The bmr-6 and bmr-12 mutations were equally efficient at reducing lignin contents (by 13% and 15%, respectively), and the effects were additive (27%) for the double mutant. Reducing lignin content was highly beneficial for improving biomass conversion yields. Sorghum biomass samples were pretreated with dilute acid and recovered solids washed and hydrolyzed with cellulase to liberate glucose. Glucose yields for the sorghum biomass were improved by 27%, 23%, and 34% for bmr-6, bmr-12, and the double mutant, respectively, compared to wild type. Sorghum biomass was also pretreated with dilute acid followed by co-treatment with cellulases and Saccharomyces cerevisiae for simultaneous saccharification and fermentation (SSF) into ethanol. Conversion of cellulose to ethanol for dilute-acid pretreated sorghum biomass was improved by 22%, 21%, and 43% for bmr-6, bmr-12, and the double mutant compared to wild type, respectively. Electron microscopy of dilute-acid treated samples showed an increased number of lignin globules in double-mutant tissues as compared to the wild-type, suggesting the lignin had become more pliable. The mutations were also effective for improving ethanol yields when the (degrained) sorghum was pretreated with dilute alkali instead of dilute acid. Following pretreatment with dilute ammonium hydroxide and SSF, ethanol conversion yields were 116 and 130mg ethanol/g dry biomass for the double-mutant samples and 98 and 113mg/g for the wild-type samples.

Our results find that the 2009 H1N1 human outbreak is closely related to swine virus, but falls into different clades in the H1 and N1 trees. Further, there is evidence of multiple viral genetic exchanges between birds and swine. Ongoing research across host species contributes to an understanding of the circulation of influenza viruses.

Our objective was to examine the effect of growth environment on biomass yield, cellulosic ethanol traits, and paper pulp fiber characteristics of alfalfa stems. Landscape position (summit and mild slope), season of harvest (four harvests per season), and multiple years (2005 and 2006) provided environmental variation. Alfalfa stem samples were analyzed for cell wall carbohydrate and lignin concentration. Stems were subjected to dilute acid pre-treatment, enzymatic saccharification, and pulping processes to measure relevant cellulosic ethanol and paper production traits. Landscape position was not a significant source of variation for yield or any biomass quality trait. Yields varied among harvests in 2005 (1,410-3,265kgha super(-1)) and 2006 (1,610-3,795kgha super(-1)). All cell wall, conversion test, and paper production traits exhibited year by harvest interactions with no clear pattern. Total carbohydrates and lignin ranged from 440 to 531gkg super(-1) DM and from 113 to 161gkg super(-1) DM, respectively. Release of cell wall sugars by the conversion test ranged widely (419 to 962gkg super(-1) DM). Fiber traits were similarly variable with length and fine content ranging from 1.24 to 1.59mm and from 15.2% to 21.9%, respectively. Utilizing alfalfa biomass for cellulosic ethanol and paper pulp production will involve dealing with significant feedstock quality variation due to growth environment.

Because it has relatively high biomass yields under relatively infrequent harvest systems, this species is receiving increasing attention as a bioenergy feedstock. The objective of this study was to conduct a comparative biomass yield evaluation of reed canary grass accessions from a wide range of habitats in the north central and northeastern USA. Eight cultivars and 72 accessions were evaluated for biomass yield over 2years at five locations in Iowa, New York, and Wisconsin. Accessions produced, on average, 6.7% higher biomass yield than the cultivars. Cultivars ranked from 50th to 77th in biomass yield out of a total of 80 cultivars and accessions. Genetic expression for biomass yield was highly consistent across locations and years. Accessions from southern and western collection sites tended to have the highest biomass yield. Reed canary grass populations in rural landscapes of the central and northeastern USA have value for increasing biomass yield potential of this bioenergy feedstock candidate species. The high biomass yield of many of these populations, combined with the large amount of genetic variability among these populations, offers potential for both short-term gains by selecting superior accessions and long-term gains by selection and breeding.

AN - 734039664; 19737057 AB - Economic pressure on the modern poultry industry has directed the selection process towards fast-growing broilers that have a reduced feed conversion ratio. Selection based heavily on growth characteristics could adversely affect immune competence leaving chickens more susceptible to disease. Since the innate immune response directs the acquired immune response, efforts to select poultry with an efficient innate immune response would be beneficial. Our laboratories have been evaluating the innate immune system of two parental broiler lines to assess their capacity to protect against multiple infections. We have shown increased in vitro heterophil function corresponds with increased in vivo resistance to Gram-positive and Gram-negative bacterial infections. Additionally, there are increased mRNA expression levels of pro-inflammatory cytokines/chemokines in heterophils isolated from resistant lines compared to susceptible lines. Collectively, all data indicate there are measurable differences in innate responsiveness under genetic control. Recently, a small-scale selection trial was begun. We identified sires within a broiler population with higher and/or lower-than-average pro-inflammatory cytokine/chemokine mRNA expression levels and subsequently utilized small numbers of high-expressing and low-expressing sires to produce progeny with increased or decreased, respectively, pro-inflammatory cytokine/chemokine profiles. This novel approach should allow us to improve breeding stock by improving the overall immunological responsiveness. This will produce a line of chickens with an effective pro-inflammatory innate immune response that should improve resistance against diverse pathogens, improve responses to vaccines, and increase livability. Ongoing work from this project is providing fundamental information for the development of poultry lines that will be inherently resistant to colonization by pathogenic and food-poisoning microorganisms. Utilization of pathogen-resistant birds by the poultry production industry would significantly enhance the microbiological safety of poultry products reaching the consumer.

AN - 734038729; 19737061 AB - Highly pathogenic avian influenza (HPAI) H5N1 is an infectious disease of fowl that can cause rapid and pervasive mortality resulting in complete flock loss. It has also been shown to cause death in humans. Although H5N1 HPAI virus (HPAIV) has not been identified in the United States, there are concerns about whether an infected flock could remain undetected long enough to pose a risk to consumers. This paper considers exposure from an Asian lineage H5N1 HPAIV-infected chicken flock given that no other flocks have been identified as H5N1 HPAIV positive (the index flock). A state-transition model is used to evaluate the probability of an infected flock remaining undetected until slaughter. This model describes three possible states within the flock: susceptible, infected, and dead, and the transition probabilities that predict movements between the possible states. Assuming a 20,000-bird house with 1 bird initially infected, the probability that an H5N1 HPAIV-infected flock would be detected before slaughter is approximately 94%. This is because H5N1 HPAIV spreads rapidly through a flock, and bird mortality quickly reaches high levels. It is assumed that approximately 2% or greater bird mortality due to H5N1 HPAIV would result in on-farm identification of the flock as infected. The only infected flock likely to reach slaughter undetected is one that was infected within approximately 3.5 days of shipment. In this situation, there is not enough time for high mortality to present. These results suggest that the probability of an infected undetected flock going to slaughter is low, yet such an event could occur if a flock is infected at the most opportune time.

AN - 734038718; 19737056 AB - All farm animals will experience some level of stress during their lives. Stress reduces the fitness of an animal, which can be expressed through failure to achieve production performance standards, or through disease and death. Stress in farm animals can also have detrimental effects on the quality of food products. However, although a common assumption of a potential effect of stress on food safety exists, little is actually known about how this interaction may occur. The aim of this review was to examine the current knowledge of the potential impact of stress in farm animals on food safety risk. Colonization of farm animals by enteric pathogens such as Escherichia coli O157:H7, Salmonella, and Campylobacter, and their subsequent dissemination into the human food chain are a major public health and economic concern for the food industries. This review shows that there is increasing evidence to demonstrate that stress can have a significant deleterious effect on food safety through a variety of potential mechanisms. However, as the impact of stress is difficult to precisely determine, it is imperative that the issue receives more research attention in the interests of optimizing animal welfare and minimizing losses in product yield and quality, as well as to food safety risks to consumers. While there is some evidence linking stress with pathogen carriage and shedding in farm animals, the mechanisms underlying this effect have not been fully elucidated. Understanding when pathogen loads on the farm are the highest or when animals are most susceptible to infection will help identifying times when intervention strategies for pathogen control may be most effective, and consequently, increase the safety of food of animal origin.

AN - 734019934; 19712151 AB - Catnip (Nepeta cataria) is known for its pseudo-narcotic effects on cats. Recently, it has been reported as an effective mosquito repellent against several Aedes and Culex species, both topically and spatially. Our laboratory bioassays showed that catnip essential oil (at a dosage of 20 mg) resulted in average repellency rates of 96% against stable flies, Stomoxys calcitrans (L.) and 79% against houseflies, Musca domestica (L.), respectively. This finding suggested that the application of repellent could be used as part of filth fly management. Further evaluations of catnip oil toxicity were conducted to provide a broad-spectrum safety profile of catnip oil use as a potential biting and nuisance insect repellent in urban settings. Acute oral, dermal, inhalation, primary dermal and eye irritation toxicity tests were performed. The acute oral LD(50) of catnip oil was found to be 3160 mg/kg body weight (BW) and 2710 mg/kg BW in female and male rats, respectively. The acute dermal LD50 was > 5000 mg/kg BW. The acute inhalation LD50 was observed to be > 10,000 mg/m3. Primary skin irritation tested on New Zealand white rabbits showed that catnip oil is a moderate irritant. Catnip oil was classified as practically non-irritating to the eye. In comparison with other U.S. Environmental Protection Agency-approved mosquito repellents (DEET, picaridin and p-menthane-3,8-diol), catnip oil can be considered as a relatively safe repellent, which may cause minor skin irritation.

AN - 733605764; 19852224 AB - Numerous spray machines are used to apply pesticides for the control of human disease vectors, such as mosquitoes and flies, and the selection and setup of these machines significantly affects the level of control achieved during an application. The droplet spectra produced by 9 different ultra-low-volume sprayers with oil- and water-based spray solutions were evaluated along with 2 thermal foggers with the use of diesel-based spray solutions. The droplet spectra from the sprayers were measured with the use of laser diffraction droplet sizing equipment. The volume median diameter from the sprayers ranged from 14.8 to 61.9 microm for the oil-based spray solutions and 15.5 to 87.5 microm for the water-based spray solutions.

AN - 733604286; 19852223 AB - An experimental study was conducted to investigate the usefulness of electrostatic and conventional sprayers for barrier applications. Two conventional and three electrostatic sprayers were used in the study. Usefulness of the sprayers was rated based on penetration of spray into and deposition onto 2 sides of leaves on natural vegetation. Bifenthrin (Talstar adulticide) was applied at labeled rate, fluorescent dye was added to the tank mix as tracer, and all sprayers applied the dye and insecticide at the same rate. The results indicated that sprayers producing larger droplets produced significantly higher deposition on vegetation in barrier applications than the sprayers producing smaller droplets. Sprayers with higher air velocity at the nozzle discharge proved significantly better for barrier sprays than the sprayers with lower air velocity. Electrostatic sprayers did not show any improvement in deposition on vegetation or in penetration into vegetation over the conventional sprayers. There was no difference in deposition between truck-mounted and backpack sprayers.

AN - 67667410; 19777905 AB - Since 11 September 2001, quality and food safety are no longer the concerns of only consumers, industry, regulatory agencies, or other government officials. Liquid foods that are prepared or stored in bulk, including liquid egg products, are considered to be at potential risk for sabotage. Because of their versatility, low price, and functional properties, many of these products are being marketed. Four of the most common products of this type are whole egg, egg albumen, 10% sugared yolk, and 10% salted yolk. Although all of the serotypes of Salmonella enterica may cause illness, multidrug-resistant Salmonella Typhimurium DT104 has become widespread and can cause severe illness that is difficult to treat. Studies were conducted to determine growth patterns of Salmonella Typhimurium DT104 in four commercial liquid egg products held at 4, 10, 20, 30, 37, and 42 degrees C for 0 to 384 h. All experiments were performed in duplicate and repeated twice. Standard methods were used to estimate cell numbers, and log CFU per gram of egg product was plotted against time. The number of cells of Salmonella Typhimurium DT104 increased to 8 to 9 log CFU/g in whole egg and 10% sugared yolk, increased by 1 log CFU/g in liquid albumen, but decreased by 3 log CFU/g in 10% salted yolk. Data from this study have been archived in the ComBase database to further assist policy makers or other scientists interested in Salmonella growth characteristics in liquid eggs. However, based on data generated in this study, Salmonella Typhimurium DT104 probably does not constitute a food threat agent in liquid eggs.

AN - 67666351; 19777880 AB - Information implicating bacterial biofilms as contributory factors in the development of environmental bacterial resistance has been increasing. There is a lack of information regarding the role of biofilms within the microbial ecology of the gastrointestinal tract of food animals. This work used a continuous-flow chemostat model derived from the ceca of 7-day-old chicks to characterize these communities and their ability to neutralize invasion by Salmonella enterica serovar Typhimurium. We characterized and compared the biofilm and planktonic communities within these microcosms using automated ribotyping and the Analytical Profile Index biotyping system. Eleven species from eight different genera were identified from six culture systems. Klebsiella pneumoniae was isolated from all planktonic communities and four of the biofilm communities. Three of the communities resisted colonization by Salmonella enterica serovar Typhimurium, two communities suppressed growth, and one community succumbed to colonization. In cultures that resisted colonization, no Salmonella could be isolated from the biofilm; in cultures that succumbed to colonization, Salmonella was consistently found within the biofilms. This study was one of a series that provided a molecular-based characterization of both the biofilm and planktonic communities from continuous-flow culture systems derived from the cecal microflora of chicks, ranging in age from day-of-hatch to 14 days old. The one common factor relating to successful colonization of the culture was the presence of Salmonella within the biofilm. The capacity to sequester the introduced Salmonella into the biofilm appears to be a contributing factor to the inability of these cultures to withstand colonization by the Salmonella.

AN - 67665232; 19769060 AB - This study was made to determine the effects of bloodmeal mass and oviparity in Aedes albopictus (Skuse) (Diptera: Culicidae) on continued host-seeking activity in female mosquitoes and efficacy of the repellent N,N-diethyl-3-methylbenzamide (DEET). There was a curvilinear relationship between bloodmeal mass in partially fed Ae. albopictus and host avidity with a threshold between 0.8 and 1.0 mg of ingested blood for reduced host seeking by female mosquitoes. Egg development and fecundity were related to bloodmeal mass, which also evoked significantly different mean host seeking rates in nulliparous and parous Ae. albopictus. The repellency of DEET to partially blood fed female mosquitoes depended on oviparity status and host avidity with repellent failure soonest in partially blood fed nullipars.

AN - 67647536; 19664794 AB - Anaerobic digestion of high-nitrogen wastes such as animal manure can be inhibited by high concentrations of un-ionized ammonia, NH(3) (aq). Understanding the toxicity of NH(3) (aq) to anaerobic digestion requires a method for determining its concentration. Previous work on ammonia toxicity in anaerobic digesters has utilized a simple equilibrium calculation for estimating NH(3) (aq) concentration from total ammonia, temperature, and pH. This approach is not appropriate for concentrated solutions. In this work, a speciation model for major solutes in anaerobic digesters, based on Pitzer's ion-interaction approach, is presented. Model simulations show that the simple equilibrium calculation (without corrections for non-ideal behavior) substantially overestimates NH(3) (aq) concentration for all but dilute digesters. This error in concentration determination increases with total solids content and is estimated to be greater than 40% for a digester fed dairy manure with 5% total solids or swine manure with 3% total solids. However, including an estimate of the activity coefficient for NH(4)(+) in the simple equilibrium calculation results in much more accurate estimates of NH(3) (aq) concentration. In this case, the estimated error is less than 10% in the absence of struvite precipitation at the highest total solids contents considered.

AN - 67614498; 19627482 AB - To determine the influence of body condition (BC) and forage type on the prevalence of faecal shedding of Escherichia coli O157:H7 and Salmonella from beef cows. Thin or moderately conditioned cows (n = 115) were randomly assigned to graze either common bermudagrass (n = 3 pastures) or toxic endophyte-infected tall fescue (n = 3 pastures) for 62 days. Faecal samples were collected on day 0, 30 and 62. Overall percentage of faecal samples positive for E. coli O157:H7 was 2.6% and 2.0% for Salmonella. Percentage of cows positive for both E. coli O157:H7 and Salmonella on at least one occasion was 6.1%. BC, forage type or the interaction did not influence the prevalence of E. coli O157:H7 or Salmonella in the faeces of cows. BC at initiation of the grazing period or loss of BC in moderate conditioned cows during the grazing period did not influence faecal shedding of E. coli O157:H7 or Salmonella. Consumption of either forage type did not influence faecal shedding of either E. coli O157:H7 or Salmonella in beef cows of thin or moderate BC. Change in BC that typically occurs during the normal production cycle in grazing cows did not influence faecal shedding of pathogenic bacteria regardless of forage type.

AN - 67613318; 19342701 AB - Selenium (Se) is essential for sperm function and male fertility, but high Se intake has been associated with impaired semen quality. We reported previously a decrease in sperm motility in men fed high-Se foods, but we could not rule out the influence of other environmental and dietary factors. We now report on a randomized, controlled study on the potential adverse effects of Se supplementation on semen quality in 42 free-living men administered Se (300 microg/d) as high-Se yeast for 48 weeks. Semen analysis was performed 4 times before treatment began, then twice each week during treatment at 6, 12, 24, 36, and 48 weeks, and then after treatment at 72 and 96 weeks. Blood samples were collected 3 times before treatment and at each subsequent visit. Se concentration increased 61% in blood plasma and 49% in seminal plasma. However, Se supplementation had no effect on sperm Se, serum androgen concentrations, or sperm count, motility, progressive velocity, or morphology. We observed progressive decreases in serum luteinizing hormone, semen volume, and sperm Se in both the high-Se and placebo groups. Moreover, sperm straight-line velocity and percent normal morphology increased in Se-treated and placebo-treated participants. The lack of an increase in sperm Se suggests that testicular Se stores were unaffected, even though the participants' dietary Se intake was tripled and their total body Se approximately doubled by supplementation. These results are consistent with animal studies showing the Se status of testes to be unresponsive to dietary Se intake.

AN - 67598060; 19517136 AB - Lignocellulosic biomass conversion inhibitors, furfural and HMF, inhibit microbial growth and interfere with subsequent fermentation of ethanol, posing significant challenges for a sustainable cellulosic ethanol conversion industry. Numerous yeast genes were found to be associated with the inhibitor tolerance. However, limited knowledge is available about mechanisms of the tolerance and the detoxification of the biomass conversion inhibitors. Using a robust standard for absolute mRNA quantification assay and a recently developed tolerant ethanologenic yeast Saccharomyces cerevisiae NRRL Y-50049, we investigate pathway-based transcription profiles relevant to the yeast tolerance and the inhibitor detoxification. Under the synergistic inhibitory challenges by furfural and HMF, Y-50049 was able to withstand the inhibitor stress, in situ detoxify furfural and HMF, and produce ethanol, while its parental control Y-12632 failed to function till 65 h after incubation. The tolerant strain Y-50049 displayed enriched genetic background with significantly higher abundant of transcripts for at least 16 genes than a non-tolerant parental strain Y-12632. The enhanced expression of ZWF1 appeared to drive glucose metabolism in favor of pentose phosphate pathway over glycolysis at earlier steps of glucose metabolisms. Cofactor NAD(P)H generation steps were likely accelerated by enzymes encoded by ZWF1, GND1, GND2, TDH1, and ALD4. NAD(P)H-dependent aldehyde reductions including conversion of furfural and HMF, in return, provided sufficient NAD(P)(+) for NAD(P)H regeneration in the yeast detoxification pathways. Enriched genetic background and a well maintained redox balance through reprogrammed expression responses of Y-50049 were accountable for the acquired tolerance and detoxification of furfural to furan methanol and HMF to furan dimethanol. We present significant gene interactions and regulatory networks involved in NAD(P)H regenerations and functional aldehyde reductions under the inhibitor stress.

AN - 67387360; 19452114 AB - Thirty-four sediment samples were collected in three water reservoirs from the Slovak Republic to investigate polycyclic aromatic hydrocarbon (PAH) distribution and predict their possible sources. The results showed that the highest total PAH concentrations were associated with sediments from the Velke Kozmalovce, ranging from 7,910 to 29,538 ng/g of dry weight. On the other hand, the lowest total PAH concentrations (84-631 ng/g of dry weight) were found in sediments of the Zemplinska Sirava, an important recreational area in eastern Slovakia. The distribution of individual PAHs was consistent within the three water reservoirs, and this together with diagnostic PAH ratios suggests mainly pyrolytic contamination of the sediments. However, petrogenic inputs appear to be important in the Zemplinska Sirava sediments.

However, serotype 4b strains cause the majority of human listeriosis outbreaks. Our investigation of L. monocytogenes biofilms used a simulated food-processing system that consisted of repeated cycles of growth, sanitation treatment, and starvation to determine the competitive fitness of strains of serotypes 1/2a and 4b in pure and mixed-culture biofilms. Selective enumeration of strains of a certain serotype in mixed-culture biofilms on stainless steel coupons was accomplished by using serotype-specific quantitative PCR and propidium monoazide treatment to prevent amplification of extracellular DNA or DNA from dead cells. The results showed that the serotype 1/2a strains tested were generally more efficient at forming biofilms and predominated in the mixed-culture biofilms. The growth and survival of strains of one serotype were not inhibited by strains of the other serotype in mixed-culture biofilms. However, we found that a cocktail of serotype 4b strains survived and grew significantly better in mixed-culture biofilms containing a specific strain of serotype 1/2a (strain SK1387), with final cell densities averaging 0.5 log10 CFU/cm2 higher than without the serotype 1/2a strain. The methodology used in this study contributed to our understanding of how environmental stresses and microbial competition influence the survival and growth of L. monocytogenes in pure and mixed-culture biofilms.

These studies have provided an insight into its central carbon metabolism, and analysis of its genome has revealed numerous functional gene clusters and tandem repeats. Specialized physiological traits are often the result of several gene products acting together. When coinheritance is necessary for the overall physiological function, recombination and selection favor colocation of these genes in a cluster. These are particularly evident in strongly conserved and idiomatic traits. In some cases, the functional clusters consist of multiple gene families. Phylogenetic analyses of the members in each family show that once formed, functional clusters undergo duplication and differentiation. Genome-wide expression analysis reveals that regulatory patterns of clusters are similar after they have duplicated and that the expression profiles evolve along with functional differentiation of the clusters. Orthologous gene families appear to arise through tandem gene duplication, followed by differentiation in the regulatory and coding regions of the gene. Genome-wide expression analysis combined with cross-species comparisons of functional gene clusters should reveal many more aspects of eukaryotic physiology.

To better understand the airborne microorganisms found in these environments, a number of collection and analytical techniques have been utilized and will be discussed in this review. The most commonly used bioaerosol collection method is the liquid impingement format, which is suitable with a number of culture-based and non-culture molecular-based approaches, such as polymerase chain reaction. However, the vast majority of airborne microorganism studies conducted at CAFOs utilize culture-based analyses. Because of the limitations often associated with culture-based analyses, we focused our discussion on the application of molecular-based techniques to identify and/or quantify microorganisms, as they have promising application in bioaerosol research. The ability to rapidly characterize airborne microorganisms will help to ensure protection of public and environmental health.

Initial inoculations established greater than 90% infection in each of the accessions, based on PCR diagnoses from petiole tissues sampled near the inoculation site. Classic leaf scorch symptoms were evident in each population during the first growing season in a controlled greenhouse environment. Trees were removed from the greenhouse during the winters to accumulate chill hours and to provide the possibility of winter curing X. fastidiosa infections. Both PCR diagnostics and in vitro cultivation were used during the second and third growing seasons to determine the persistence of X. fastidiosa in clones among the three populations. Tree survival and the degree of winter cured infections differed among the three populations, with P. webbii and P 63-61 demonstrating enhanced levels of survivorship over 'Butte.' After two cycles of ambient winter temperatures and subsequent growth, 'Butte' averaged 21.2% winter cured trees with 73.1% mean survival. Tree survival and winter cured infections were nearly 100% for both P. webbii and P 63-61, demonstrating the utility of P. webbii in almond breeding efforts aimed at reducing tree vulnerability to X. fastidiosa infections.

Diatoms, macroinvertebrates, fishes, suspended sediment, dissolved solids, and bed composition were measured at two reference sites and six sites where a socioeconomic model suggested new building construction would influence stream ecosystems in the future; we label these 'hazard sites.' The six hazard sites were located in catchments with forested and agricultural land use histories. Diatoms were species-poor at reference sites, where riparian forest cover was significantly higher than all other sites. Cluster analysis, Wishart's distance function, non-metric multidimensional scaling, indicator species analysis, and t-tests show that macroinvertebrate assemblages, fish assemblages, in situ physical measures, and catchment land use and land cover were different between streams whose catchments were mostly forested, relative to those with agricultural land use histories and varying levels of current and predicted development. Comparing initial results with other regional studies, we predict homogenization of fauna with increased nutrient inputs and sediment associated with agricultural sites where more intense building activities are occurring. Based on statistical separability of sampled sites, catchment classes were identified and mapped throughout an 8,600km super(2) region in western North Carolina's Blue Ridge physiographic province. The classification is a generalized representation of two ongoing trajectories of land use change that we suggest will support streams with diverging biota and physical conditions over the next two decades.

Currently, dozens of rice resistance (R) genes against specific races of the blast fungus have been described. Among them, ten were molecularly characterized and some were widely used for breeding for genetic resistance. The Pi-ta gene was one of the best characterized rice R genes. Following the elucidation of its molecular structure, interaction, distribution, and evolution, user friendly DNA markers were developed from portions of the cloned genes to facilitate the incorporations of the Pi-ta mediated resistance into improved rice varieties using marker assisted selection (MAS). However, rice blast is still a major threat for stable rice production because of race change mutations occurring in rice fields, which often overcome added resistance based on single R genes, and these virulent races of M. oryzae pose a continued challenge for blast control. For sheath blight, progress has been made on the exploration of novel sources of resistance from wild rice relatives and indica rice cultivars. A major quantitative trait locus (QTL), named qSB9-2, was recently verified in several mapping populations with different phenotyping methods, including greenhouse methods. The ability to identify qSB9-2 using greenhouse methods should accelerate the efforts on the qSB9-2 fine mapping and positional cloning.

Biomass in the form of coarse woody residues remaining after traditional timber harvest in the southeastern USA is a potentially significant source of biomass for bioenergy. Questions remain regarding whether the removal of this material would constitute a sustainable silvicultural practice given the potential impact on soil nutrient cycling and other ecosystem functions. Our objective is to review existing studies to estimate quantities of residual materials on southern pine forests that may be available, potential nutrient removals, and potential replacement with fertilizer. Regionally, it is estimated that 32 million Mg year super(-1) of dry harvest residues may be available as a feedstock. At the stand level, between 50 and 85Mg ha super(-1) of material is left on site after typical stem-only harvests, of which half could be removed using chippers at the landing. Based on these estimates, increase in midrotation fertilization rates of 45% to 60% may be needed on some sites to fully replace the nutrients from harvesting residues removed for bioenergy. Field experiments suggest that residue removals do not degrade forest productivity in many cases, but more data are needed to assess the effects of frequent removals (i.e., from short-rotation systems) over longer periods and identify sites that may be particularly sensitive to the practice. A benefit of developing markets for previously nonmerchantable materials may create incentives for improved forest management by landowners.

The effects of overstory leaf area index (LAI), percentage understory light transmittance (LT), and soil moisture (SM) on yield and crude protein (CP) of big bluestem [Andropogon gerardii Vitman; (BB)], smooth bromegrass [Bromus inermis Leyss.; (SB)], and mixtures with birdsfoot trefoil [Lotus corniculatus L.; (BFT)] were examined. The study was conducted in both Scotch pine (Pinus sylvestris L.) and green ash (Fraxinus pennsylvancia Marsh.) tree plantations, at the University of Nebraska Agriculture Research and Development Center near Mead, Nebraska. Thirty-six plots representing a wide range of canopy cover were selected at each location and seeded in April 2000 to BB, SB, or mixtures with BFT. Measurements of LAI, LT, and SM were taken throughout the 2001-growing season and plots were harvested in June and September 2001. Soil moisture generally did not explain much of the variability in yield or CP for BB, SB, or BFT. Cumulative LAI or LT averaged over the growing season was the best predictor of yield or CP, particularly under the pine. Yields of BB and SB increased as LAI decreased or LT increased. Conversely, the CP of BB and SB increased as LT decreased for both the June and September harvests. Both BB and SB maintain relatively high productivity under partial shading; however, BFT yields were low at LT levels below 75%.

However, most EB models are complex to use and efforts are being made to simplify procedures mainly through the scaling of reference ET. The Simplified Surface Energy Balance (SSEB) is one such method. This approach has never been evaluated using measured ET data. In this study, the SSEB approach was applied to 14 Landsat TM images covering a major portion of the Southern High Plains that were acquired during 2006 and 2007 cropping seasons. Performance of the SSEB was evaluated by comparing estimated ET with measured daily ET from four large monolithic lysimeters at the USDA-ARS Conservation and Production Research Laboratory, Bushland, Texas. Statistical evaluation of results indicated that the SSEB accounted for 84% of the variability in the measured ET values with a slope and intercept of 0.75 and 1.1 mm d(-1), respectively. Considering the minimal amount of ancillary data required and excellent performance in predicting daily ET, the SSEB approach is a promising tool for mapping ET in the semiarid Texas High Plains and in other parts of the world with similar hydro-climatic conditions.

Chemigation is a widely adopted practice with center pivot sprinkler irrigation. However, the practice of chemical injection at a constant rate with center pivot sprinkler irrigation systems equipped with an end gun and/or swing-arm corner watering system results in systematic chemical application errors ranging from 7% to 21% due to systematic changes in system flow rate. Chemical injection proportional to center pivot sprinkler system flow rate is one approach to reduce systematic chemical application errors. The objective of this project was to test the feasibility of using real-time monitoring of center pivot sprinkler irrigation system operating status to control chemical injection rate proportional to calculated system flow rate, thus minimizing systematic chemical application errors. A spatially distributed control network was developed to facilitate real-time monitoring of end gun and swing-arm corner watering system operating status and pressure. The spatially distributed control network consisted of three network nodes at specific locations along a center pivot sprinkler irrigation lateral that used the 480 VAC 3-phase power cable on the center pivot sprinkler irrigation system as the communication medium. The spatially distributed control network was installed on a commercial 460-m (1510-ft) long center pivot sprinkler system equipped with an end gun and swing-arm corner watering system. Performance of chemical injection proportional to calculated flow rate based on real-time center pivot sprinkler irrigation system operating status was evaluated by injecting Rhodamine WT dye into the center pivot sprinkler irrigation system water supply and measuring its concentration in the applied water. Mean dye concentration varied by 26% under constant rate chemical injection and 2% under flow proportional chemical injection due to systematic changes in center pivot sprinkler irrigation system flow rate. Use of the flow proportional chemical injection system reduced the coefficient of variability in measured dye concentration of applied water by 54% from 0.100 to 0.046. Use of the spatially distributed control network for calculating center pivot sprinkler system flow rate eliminates the need for straight sections of unobstructed piping at the chemical injection site. Display and/or data logging of real-time center pivot sprinkler operating status is an added benefit of using the spatially distributed control network This information provides the ability to monitor, diagnose, and troubleshoot center pivot sprinkler system operation. Commercialization and adoption of the technology could reduce systematic chemical application errors and facilitate maintenance and operation of center pivot sprinkler irrigation systems equipped with an end gun and/or swing-arm corner watering system.

Channel catfish were exposed in 1-L immersion baths containing 10 super(8), 10 super(9), 10 super(10), 10 super(11), or 10 super(12) colony-forming units (cfu) of S. ictaluri. Fish were also injected intraperitoneally with 0.1 mL of bacterial solution for final doses of 10 super(4), 10 super(5), 10 super(6), 10 super(7), or 10 super(8) cfu of S. ictaluri per fish. Streptococcus ictaluri caused mortality in fry, fingerling, and juvenile channel catfish within 21 d postinfection. When mortalities were calculated based on size and challenge route, the cumulative percent mortalities were 11% for fry and 0% for fingerlings by the bath immersion route and 14% for fingerlings and 6% for juveniles by the injection route. Isolation of S. ictaluri from moribund and dead catfish was confirmed by the newly established BIOLOG profile (MicroLog3 system). The results indicate that channel catfish were only susceptible to high concentrations of S. ictaluri and that juvenile channel catfish were less susceptible, possibly explaining why little mortality has been attributed to S. ictaluri infection in catfish aquaculture.

(Capparaceae) during exploration for caterpillars in the Area de Conservacion Guanacaste (ACG), Costa Rica. Cosmopterosis is revised and now includes four species. Three new species, C. hispida, C. jasonhalli, and C. spatha, and the immatures of C. spatha and biology for two species, C. jasonhalli and C. spatha, are described; the type species, C. thetysalls (Walker), is redescribed. A key and illustrations for the identification of the species is provided. We propose a hypothesis for the relationship between species in Cosmopterosis and the placement of Cosmopterosis in the subfamily. The cladistic analysis, the first such analysis in the Glaphyriinae, included 21 morphological characters one of which, the radiodiscal process, a male secondary sexual character and presumably an androconial scent pouch is described and considered a autapomorphy for the genus. Male secondary sexual characters and larval feeding on Capparis in Pyraloidea and Lepidoptera is discussed.

In Washington County, MS, field parasitization rates of nymphal mantids in old-field sites exceeded 80% in late summer and were associated with a delay in maturation of parasitized nymphs. Laboratory rearings and dissections indicated that early-stage parasites had entered at the lateral mesothorax and were free-moving in the host thorax, with late-stage larvae attached to the inner wall of the fifth abdominal segment. A sclerotized airhole was present at the attachment site and exit holes for the mature larvae were in the area of the second abdominal segment. When attached, the parasite was encased in a sac and a sclerotized respiratory funnel was formed. After parasite emergence, the host typically died within 24 h, although some host individuals survived for up to 29 d and some individuals fed and partially molted after parasite emergence under ambient conditions. Pupation of parasites under ambient conditions occurred in the soil in September and October, with subsequent emergence in the following May.

However, very few studies have systematically explored the impacts on a whole suite of species over a wide geographic region. In an effort to do so, we have developed two atlases (www/nrs.fs.fed.us/ atlas) related to 134 tree and 147 bird species of the eastern United States (nearly all species in the region with sampling and observations adequate for statistical modeling). The atlases provide distributional, ecological, and biological information on these species, as well as modelled results on current and potential future habitats. Our purpose, in addition to providing extensive species-specific and combined-species information, is to help managers and restoration ecologists get a clearer picture of how possible habitat changes may impact their county, state, national forest, or other areas of interest.

AN - 21135090; 11147572 AB - American chestnut (Castanea dentata) was once a dominant hardwood species in the eastern United States, growing from Maine to Georgia and west to the Ohio Valley (Harlow et al. 1979). Arguably, American chestnut may have been the most important hardwood species in North America, renowned for its quick growth, massive size, and great utility (Harlow et al. 1979). Unfortunately, within 50 years of the introduction of chestnut blight (Cryphonectria parasitica)--a fungal disease native to Asia--American chestnut was functionally removed as an overstory tree from eastern forests (Griffin 2000).

The objectives of this research were to (1) test if broiler litter improves plant macronutrient (N, P, K, and Mg) nutrition of cotton above that of cotton fertilized with conventional inorganic fertilizers and (2) determine if lack of incorporating litter into the soil reduces macronutrient concentration in cotton plant parts in an upland soil considered marginal for cotton. Six treatments consisting of an unfertilized control, a fertilized standard (STD), two litter-only, and two litter plus inorganic N as urea-ammonium nitrate solution (UAN) were tested in two adjacent fields, one under no-till (NT) and the other under conventional-till (CT) systems. Litter alone, UAN, or a combination of litter plus UAN were applied to supply 101 kg ha super(-1) plant available N assuming nearly all of the UAN-N and 50% of the total litter N becomes plant available during the cotton growing season. Concentration of N, P, K, and Mg were measured in leaves, stems, and reproductive parts on three or four dates between early flowering and maturity. Cotton fertilized with the litter-only treatments always had less N concentration but greater P and K concentration in leaves, stems, and reproductive parts than cotton that received the STD treatment. Leaf and stem Mg concentration seems to depend on the N concentration in these plant parts. Lack of incorporating litter into the soil reduced N concentration in nearly all plant parts at all growth stages, suggesting some amount of the litter-derived N is lost due to lack of incorporation. Lack of incorporation also reduced leaf and stem Mg concentration, which seemed to be due to its reducing effect on N concentration. Unlike N and Mg, lack of incorporation did not consistently affect concentrations of P and K in all plant parts. Regardless of the incorporation treatment, fertilization with the litter-only treatments increased tissue P and K concentration and supported lint yield exceeding that of the STD without increasing tissue N concentration.

The effects of divergent land management strategies on the incidence and infectivity of AM and other fungal root endophytes were evaluated in a 5-year tomato (Lycopersicon esculentum Mill.) cropping systems study. Two of the five treatments utilized farming practices considered detrimental to AM fungal populations, including the tillage-mediated elimination of vegetation and soil fumigation. The remaining three treatments used practices thought to be more conducive to the presence of AM fungi, including organic production methods, bahiagrass pasture and undisturbed weed fallow. In years four and five of the study tomato roots and rhizosphere soil were collected. Roots were examined for colonization by AM and other fungal root endophytes, and rhizosphere soil was assayed to measure the amount of infective inoculum present based on maize (Zea mays L.) seedling infection. Tomato roots and rhizosphere soil were also analyzed for the AM fungal fatty acid biomarker 16:1[Omega]5c. Sudangrass (Sorghum sudanense (Piper) Stapf) trap cultures were initiated using field soil to assess the diversity of AM fungal spore morphotypes. Soil disturbance and phosphorus (P) levels had the greatest influences on AM fungal infectivity and abundance. All plots had high levels of available soil P, resulting in low levels of colonization across treatments. Bahiagrass (Paspalum notatum Flugge) pasture was the only treatment without repeated, intensive soil mixing, and had the highest level of field root colonization by AM fungi. Field roots were more heavily colonized by other fungal endophytes than by AM fungi in all treatments. Tomato roots from organic plots were apparently unique in encouraging colonization by fungi that appeared to be Microdochium bolleyi (R. Sprague) de Hoog & Herm.-Nijh. Infection by AM and other fungal root endophytes were positively correlated in all studies. Flooding and a shortened growing season likely contributed to reduced infection potentials in all treatments except for organic plots in year five compared to year four. Areas of high disturbance from frequent tillage had the lowest levels of primary inoculum, but recovery to levels comparable to less disturbed treatments occurred after a single season of host root growth. Diversity of AM fungal morphotypes was typical of agricultural fields, with at least 10 spore morphotypes present across treatments; Glomus spp. were the dominant spore type recovered in all treatments.

Therefore, this study examined the sensitivity of cypress-pine flatwoods hydrology to climate change and forest management by using the physically based, distributed hydrologic modeling system, MIKE SHE. The model was first calibrated and validated with a long-term data set, and then applied using several hypothetical scenarios developed in north central Florida. Our study showed that MIKE SHE could simulate the temporal and spatial dynamics of the shallow ground-water table. The model also identified and confirmed three horizontal ground-water flow patterns at this study site. The modeling results suggested that forest removal and climate change (i.e., warming and drying) would have pronounced impacts on the ground-water table during the dry periods, but these impacts may be minor under wet conditions at this typical flatwoods landscape. At the landscape scale, depressional wetlands may have higher responses to tree removal and climate change than surrounding uplands.

Results show that organic market shares within the fresh fruit and vegetable sectors grew slightly in 2003-2006. Apples, bananas, carrots, and tomatoes prove to have the highest share of organic sales within their sectors. The share of organic milk sales attributed to private labels has increased from 12 to 32 percent in 2004-2007. The organic market share within the strained baby food sector almost doubled from 8 to 15 percent in 2004-2007. Findings show a demographically diverse group of consumers willing to expend their food dollars on organic foods.

The study fills an important research void by estimating the much needed income and price elasticities for organic and conventional fruits utilizing a censored demand approach. Household income is found to affect organic fruit consumption. Consumers are more responsive to price of organic fruits than to price of conventional fruits. Cross-price effects suggest that a change in relative prices will more likely induce consumers to "cross-over" from buying conventional fruits to buying organic fruits, while it is less likely that organic consumers will "revert" to buying conventional fruits.

Oocyst transport to surface water can occur by deposition of manure directly in the water or by wash off in surface runoff. Oocyst transport to groundwater is less straightforward and requires that the oocysts move through soil and bedrock to reach the water table. The purpose of this study was to determine the relative concentration and infectivity of C. parvum oocysts released from manure and leached through columns of undisturbed, macroporous karst soil. Modeling the fate of oocysts in this system over time can provide baseline data for evaluating real world events. Substantially more oocysts leached from undisturbed soil columns than disturbed soil columns. Oocyst survival studies using BALB/c neonatal suckling mice showed that about 85% of oocysts were infective at the beginning of leaching experiments. The oocyst infectivity decreased to about 20% after 12weeks of leaching from soil columns maintained at 10C. Cool (10C) temperatures appear to increase survivability and maintain infectivity of many oocysts for 3months or longer. Cool temperatures also appear to increase rates of release of oocysts from manure and leaching through soil. This study demonstrated that leaching is an important mechanism of oocyst transport in karst soils where infiltration capacities are high and long, continuous macropores exist. Karst groundwater systems might be especially vulnerable to contamination by leached oocysts, because of the prevalence of shallow soils and rapid groundwater movement. Oocysts leaching from soils into the epikarst could accumulate and remain viable for months until hydrological conditions are right for flushing the oocysts into the conduit flow system.

Such compounds have the potential to inactivate pathogenic bacteria on contact and in the vapor phase. Edible films made from fruits or vegetables containing EOs can be used commercially to protect food against contamination by pathogenic bacteria. EOs from cinnamon, allspice, and clove bud plants are compatible with the sensory characteristics of apple-based edible films. These films could extend product shelf life and reduce risk of pathogen growth on food surfaces. This study evaluated physical properties (water vapor permeability, color, tensile properties) and antimicrobial activities against Escherichia coli O157:H7, Salmonella enterica, and Listeria monocytogenes of allspice, cinnamon, and clove bud oils in apple puree film-forming solutions formulated into edible films at 0.5% to 3% (w-w) concentrations. Antimicrobial activities were determined by 2 independent methods: overlay of the film on top of the bacteria and vapor phase diffusion of the antimicrobial from the film to the bacteria. The antimicrobial activities against the 3 pathogens were in the following order: cinnamon oil > clove bud oil > allspice oil. The antimicrobial films were more effective against L. monocytogenes than against the S. enterica. The oils reduced the viscosity of the apple solutions and increased elongation and darkened the colors of the films. They did not affect water vapor permeability. The results show that apple-based films with allspice, cinnamon, or clove bud oils were active against 3 foodborne pathogens by both direct contact with the bacteria and indirectly by vapors emanating from the films.

This surface vesicular horizon is characterized by non-connected pores that hinder soil water infiltration and thus plays a central role in arid ecosystem hydrodynamics. Disturbance is hypothesized to result in a change in pore morphology that could alter water movement through the horizon and potentially affect ecosystem function. To test this hypothesis, we examined the pore morphology of the vesicular horizon as expressed in area, perimeter, length and width; comparisons were also made for particle size, pH, calcium carbonate equivalent (CCE), electrical conductivity (EC) and the abundance and types of pores in undisturbed soils and adjacent disturbed soils within a year of disturbance. The results indicate no significant differences between treatments in chemistry, particle size or pore morphological measures within a year following disturbance. Vesicles, vughs and interstitial pores were found in vesicular horizons in both treatments and no significant differences in these parameters were found between treatments. Vesicular horizon development may be related to the geological age of the surface materials. Certain old land surfaces are perhaps more susceptible to the formation of vesicular horizons regardless of disturbance. The results suggest that soil functions dependent upon vesicular porosity, for example hydraulic conductivity, may return to a pre-disturbance condition within one year of disturbance, a finding of importance to the management of arid lands.

Antimicrobial activities were determined by 2 independent methods: overlay of the film on top of the bacteria and vapor-phase diffusion of the antimicrobial from the film to the bacteria. The results indicate that the antimicrobial activities against the 3 pathogens were in the following order: oregano oil > allspice oil > garlic oil. Listeria monocytogenes was less resistant to EO vapors, while E. coli O157:H7 was more resistant to EOs as determined by both overlay and vapor-phase diffusion tests. The presence of plant EO antimicrobials reduced the viscosity of TPFFS at the higher shear rates, but did not affect water vapor permeability of films. EOs increased elongation and darkened the color of films. The results of the present study show that the 3 plant-derived EOs can be used to prepare tomato-based antimicrobial edible films with good physical properties for food applications by both direct contact and indirectly by vapors emanating from the films.

Odum delivered a speech before the Ecological Society of America that transformed the way ecologists looked at succession. His comparison of mature and successional systems lead ecologists to place secondary forests in an inferior position relative to mature ones to the point that today, prominent tropical biologists argue for and against the conservation value of secondary forests. Nevertheless, we live in the era of secondary forests that is rapidly giving way to a new era of novel tropical forests. Research in Puerto Rico documents the emergence of novel forests, which are different in terms of species composition, dominance, and relative importance of species from forests that were present before the island was deforested. These novel forests emerged without assistance. They are a natural response to the new environmental conditions created by human activity. Natural processes have remixed or reassembled native and introduced plant and animal species into novel communities adapted to anthropogenic environmental conditions. Novel forests are expected to protect soils, cycle nutrients, support wildlife, store carbon, maintain watershed functions, and mitigate species extinctions. The dawn of the age of tropical novel forests is upon us and must not be ignored.Abstract in Spanish is available at http://www.blackwell-synergy.com/loi/btp.

Many forests in the western United States are being treated to reduce fuels, yet the effects of these treatments on forest carbon are not well understood. We compared the immediate effects of fuels treatments on carbon stocks and releases in replicated plots before and after treatment, and against a reconstruction of active-fire stand conditions for the same forest in 1865. Total live-tree carbon was substantially lower in modern fire-suppressed conditions (and all of the treatments) than the same forest under an active-fire regime. Although fire suppression has increased stem density, current forests have fewer very large trees, reducing total live-tree carbon stocks and shifting a higher proportion of those stocks into small-diameter, fire-sensitive trees. Prescribed burning.released 14.8 Mg C/ha, with pre-burn thinning increasing the average release by 70% and contributing 21.9-37.5 Mg C/ha in miffing waste. Fire suppression may have incurred a double carbon penalty by reducing stocks and contributing to emissions with fuels-treatment activities or inevitable wildfire combustion. All treatments reduced fuels and increased fire resistance, but most of the gains were achieved with understory thinning, with only modest increases in the much heavier overstory thinning. We suggest modifying current treatments to focus on reducing surface fuels, actively thinning the majority of small trees, and removing only fire-sensitive species in the merchantable, intermediate size class. These changes would retain most of the current carbon-pool levels, reduce prescribed burn and potential future wildfire emissions, and favor stand development of large, fire-resistant trees that can better stabilize carbon stocks.

We aimed to test if this were true at agronomic rates [low (11 kg N ha super(-1)), moderate (56 kg N ha super(-1)), and high (112 kg N ha super(-1))] for central North Dakota arable and prairie soils using intact soil cores to minimize disturbance and simulate field conditions. Additions of urea to cores incubated at 21 C and 57% water-filled pore space enhanced fluxes of CO sub(2) but not CH sub(4) and N sub(2)O. At low, moderate, and high urea-N, CO sub(2) fluxes were significantly greater than control but not fluxes of CH sub(4) and N sub(2)O. The increases in CO sub(2) emission with rate of urea-N application indicate that agronomic-scale N inputs may stimulate microbial carbon cycling in these soils, and that the contribution of CO sub(2) to net greenhouse gas source strength following fertilization of semi-arid agroecosystems may at times be greater than contributions by N sub(2)O and CH sub(4).

However, the response of plant communities to disturbance may be fundamentally altered as a consequence of invasive plants, climate change, or prior disturbances. The appropriateness of historical disturbance patterns under modern conditions and the interactions among disturbances are issues that ecologists must address to protect and restore native plant communities. We evaluated the response of Artemisia tridentata ssp. wyomingensis (Beetle & A. Young) S.L. Welsh plant communities to their historical disturbance regime compared to other disturbance regimes. The historical disturbance regime of these plant communities was periodic fires with minimal grazing by large herbivores. We also investigated the influence of prior disturbance (grazing) on the response of these communities to subsequent disturbance (burning). Treatments were: (1) ungrazed (livestock grazing excluded since 1936) and unburned, (2) grazed and unburned, (3) ungrazed and burned (burned in 1993), and (4) grazed and burned. The ungrazed-burned treatment emulated the historical disturbance regime. Vegetation cover, density, and biomass production were measured the 12th, 13th, and 14th year post-burning. Prior to burning the presence of Bromus tectorum L., an exotic annual grass, was minimal (<0.5% cover), and vegetation characteristics were similar between grazed and ungrazed treatments. However, litter accumulation was almost twofold greater in ungrazed than in grazed treatments. Long-term grazing exclusion followed by burning resulted in a substantial B. tectorum invasion, but burning the grazed areas did not produce an invasion. The ungrazed-burned treatment also had less perennial vegetation than other treatments. The accumulation of litter (fuel) in ungrazed treatments may have resulted in greater fire-induced mortality of perennial vegetation in ungrazed compared to grazed treatments. Our results demonstrate that prior disturbances exert a strong influence on the response of plant communities to subsequent disturbances and suggest that low-severity disturbances may be needed in some plant communities to increase their resilience to more severe disturbances. Modern deviations from historical conditions can alter ecosystem response to disturbances, thus restoring the historical disturbance regime may not be an appropriate strategy for all ecosystems.

Forest and pasture soils from two depths were treated for 1 h with cool (23 super( degree )C) water (Control) or solutions that added 10 mg g super(-1) soil tannic acid (TA), an imprecisely defined mixture of galloyl esters, gallic acid (GA), a phenol, or beta -1,2,3,4,6-penta-O-galloyl-d-glucose (PGG), a hydrolyzable tannin. Soluble-C and N, in treatment supernatants, was measured to uncover evidence for sorption of treatments or effects on extraction of soil-N. Significant amounts of soluble-C, added with treatments, were not recovered in supernatants indicating sorption of nearly 90% of the PGG-C, about 75% of the TA-C but less than 25% of the GA-C in surface soil. Disappearance of soluble-C from treatment supernatants was accompanied by a corresponding reduction of total phenolic content. Treatments added a negligible amount of N to soil; but while PGG and TA reduced soluble-N, in extracts from surface soil, GA had little effect. Soluble-N in extracts was composed mainly of organic-N. Effects of tannins persisted in surface soil through 12 washings with hot water (80 super( degree )C), suggesting the formation of stable complexes with soil. The proportion of initial soil-C and N remaining after all extractions was higher in samples treated with PGG or TA than either the Control or GA treatment. We conclude PGG readily sorbs to soil and reduces the solubility of soil organic-N unlike GA, its simple monomeric constituent. These differences could be especially important near the surface where quantities of soil organic matter and biological activity are comparatively large and most easily affected by management.

Here, we report the isolation and functional characterization of five new CLE genes from the potato cyst nematode Globodera rostochiensis. Unlike typical plant CLE peptides that contain a single CLE motif, four of the five Gr-CLE genes encode CLE proteins with multiple CLE motifs. These Gr-CLE genes were found to be specifically expressed within the dorsal esophageal gland cell of nematode parasitic stages, suggesting a role for their encoded proteins in plant parasitism. Overexpression phenotypes of Gr-CLE genes in Arabidopsis mimicked those of plant CLE genes, and Gr-CLE proteins could rescue the Arabidopsis clv3-2 mutant phenotype when expressed within meristems. A short root phenotype was observed when synthetic GrCLE peptides were exogenously applied to roots of Arabidopsis or potato similar to the overexpression of Gr-CLE genes in Arabidopsis and potato hairy roots. These results reveal that G. rostochiensis CLE proteins with either single or multiple CLE motifs function similarly to plant CLE proteins and that CLE signaling components are conserved in both Arabidopsis and potato roots. Furthermore, our results provide evidence to suggest that the evolution of multiple CLE motifs may be an important mechanism for generating functional diversity in nematode CLE proteins to facilitate parasitism.

A single dominant gene is responsible for resistance to race 1 reproduction on the root system. An additional form of resistance was discovered in certain advanced backcross clones. A BC sub(5) clone, PA99N82-4, resisted invasion of tubers by available nematode juveniles whether supplied by weeds or challenged by several root resistance-breaking pathotypes. This tuber resistance is inherited as a single dominant gene and is linked to R sub(Mc1(blb)). Because this gene has been mapped to chromosome 11, tuber resistance genetic factors are inferred to be on the same chromosome in coupling phase. Among 153 progeny derived from crosses with PA99N82-4, 42 recombinants, comprising both resistant root/susceptible tuber and susceptible root/resistant tubers, were found while other progeny were doubly resistant (like PA99N82-4) or doubly susceptible. Therefore, the existence of two linked genetic factors controlling independently expressed traits is confirmed. The combination of the two phenotypes is likely to be a sufficient level of resistance to avoid tuber damage from circumstances that provide exogenous juveniles proximal to the tubers in the soil. These factors are weed hosts of M. chitwoodi host races and pathotypes of M. chitwoodi that overcome R sub(Mc1(blb)). Under field conditions, where a resistance-breaking pathotype of M. chitwoodi was present, tuber-resistant PA99N82-4 breeding line produced tubers which were commercially acceptable and not culled. A related breeding line, root resistant but tuber susceptible, and Russet Burbank were severely tuber damaged and commercially unacceptable.

Jasmine 85 is an indica cultivar that has proven to have a high level of resistance to this pathogen. The objective of this study was to determine the ability of controlled environment inoculation assays to detect ShB resistance quantitative trait loci (QTLs) in a cross derived from the susceptible cv. Lemont and the resistant cv. Jasmine 85. The disease reactions of 250 F sub(5) recombinant inbred lines (RILs) were measured on the seedlings inoculated using microchamber and mist-chamber assays under greenhouse conditions. In total, 10 ShB-QTLs were identified on chromosomes 1, 2, 3, 5, 6, and 9 using these two methods. The microchamber method identified four of five new ShB-QTLs, one on each of chromosomes 1, 3, 5, and 6. Both microchamber and mist-chamber methods identified two ShB-QTLs, qShB1 and qShB9-2. Four of the ShB-QTLs or ShB-QTL regions identified on chromosomes 2, 3, and 9 were previously reported in the literature. The major ShB-QTL qShB9-2, which cosegregated with simple sequence repeat (SSR) marker RM245 on chromosome 9, contributed to 24.3 and 27.2% of total phenotypic variation in ShB using microchamber and mist-chamber assays, respectively. qShB9-2, a plant-stage-independent QTL, was also verified in nine haplotypes of 10 resistant Lemont/Jasmine 85 RILs using haplotype analysis. These results suggest that multiple ShB-QTLs are involved in ShB resistance and that microchamber and mist-chamber methods are effective for detecting plant-stage-independent QTLs. Furthermore, two SSR markers, RM215 and RM245, are robust markers and can be used in marker-assisted breeding programs to improve ShB resistance.

MR has been reported from Serbia, Romania, and Bulgaria for 50 years, and recent epiphytotics reduced yields by 40 to 90% in South Banat District, Serbia. Potential vectors including leafhoppers and planthoppers in the order Hemiptera, suborder Auchenorrhyncha, were surveyed in MR-affected and low-MR-incidence fields, and 33 different species were identified. Only Reptalus panzeri populations displayed characteristics of a major MR vector. More R. panzeri individuals were present in MR-affected versus low-MR fields, higher populations were observed in maize plots than in field border areas, and peak population levels preceded the appearance of MR in late July. Stolbur phytoplasma was detected in 17% of R. panzeri adults using nested polymerase chain reaction but not in any other insects tested. Higher populations of R. panzeri nymphs were found on maize, Johnsongrass (Sorghum halepense), and wheat (Triticum aestivum) roots. Stolbur phytoplasma was detected in roots of these three plant species, as well as in R. panzeri L sub(3) and L sub(3) nymphs. When stolbur phytoplasma-infected R. panzeri L sub(3) nymphs were introduced into insect-free mesh cages containing healthy maize and wheat plants, 89 and 7%, respectively, became infected. These results suggest that the MR disease cycle in South Banat involves mid-July transmission of stolbur phytoplasma to maize by infected adult R. panzeri. The adult R. panzeri lay eggs on infected maize roots, and nymphs living on these roots acquire the phytoplasma from infected maize. The nymphs overwinter on the roots of wheat planted into maize fields in the autumn, allowing emergence of phytoplasma-infected vectors the following July.

Most experiments were performed with a single P. ramorum isolate from the NA1 clonal lineage. For whole plants incubated in dew chambers at 10 to 31 C, the greatest proportion of diseased leaves, 77.5%, occurred at the optimum temperature of 20.5C. Disease occurred over the entire range of temperatures tested, although amounts of disease were minor at the temperature extremes. For whole plants exposed to varying dew periods at 20C and then incubated at 20C for 7 days, a dew period as short as 1 h resulted in a small amount of disease; however, at least 4 h of dew were required for >10% of the leaves to become diseased. Moisture periods of 24 and 48 h resulted in the greatest number of diseased leaves. In detached-leaf, temperature-gradient-plate experiments, incubation at 22C resulted in the greatest disease severity, followed by 18C and then 14C. In detached-leaf, moisture-tent experiments, a 1-h moisture period was sufficient to cause disease on 67 to 73% of leaves incubated for 7 days at 20C. A statistical model for disease development that combined the effects of temperature and moisture period was generated using nonlinear regression. Our results define temperature and moisture conditions which allow infection by P. ramorum on Cunningham's White rhododendron, and show that P. ramorum is able to infect this host over a wide range of temperatures and moisture levels. The results indicate that P. ramorum has the potential to become established in parts of the United States that are outside its current range.

To avoid excessive vibration, producers generally reduce operating speeds that increase the time needed to perform the field operation. The objectives of this research were to identify roller crimper designs that terminated rye cover crops consistently, resulted in soil moisture conservation after use, and minimized vibrations when operated in the field. Six different roller types were developed and tested at 3.2 and 6.4 km h-1 in Alabama field experiments during the 2006, 2007 and 2008 growing seasons. All roller types were used alone and one also in combination with glyphosate. Rye mortalities were evaluated 1, 2 and 3 weeks after rolling and compared with the check (non-rolled standing rye). Soil volumetric moisture content (VMC) was measured at the day of rolling, and then at 1, 2 and 3 weeks after rolling. Vibration was measured on the rollers' and tractor's frames during operation. Mortality for rolled rye 2 weeks after rolling was at least 98% compared with 96% for the check in 2006, 93% for rolling compared with 75% for the check in 2007, and 94% for rolling compared with 60% for the check in 2008 (P<0.10). There were no consistent differences in rye mortality across roller types (without glyphosate) and speeds. VMC for soil in non-rolled rye plots was consistently lower than in rolled rye plots, averaging 3% compared with 7% 2 weeks after rolling in 2006, and 4% compared with 8% in 2008. During 2007, VMC was affected by severe drought conditions, and differences between roller treatments were detected but minor. The straight-bar roller generated the highest vibration on the tractor's frame at 6.4 km h-1 (0.71 m s-2, RMS), which exceeded International Standards (International Standard Office (ISO)). At 6.4 km h-1, new roller designs generated significantly lower acceleration levels from 0.12 to 0.32 m s-2 on the tractor's frame and were below detrimental effects on health 'health limits' classified by ISO. Overall, 2 weeks after rolling, all roller designs effectively terminated rye above 90%, which is the recommended termination level of rye to plant a cash crop into residue mat, while protecting soil surface from water loss. New roller designs generate less vibration than the original design and can be used safely at higher operating speeds.

The following changes were observed for B20 blends of SME and PHSME versus neat ULSD: improved lubricity, higher kinematic viscosity and cetane number, lower sulfur content, and inferior low-temperature properties and oxidative stability. With respect to exhaust emissions, B20 blends of PHSME and SME exhibited lower PM and CO emissions in comparison to those of neat ULSD. The PHSME blend also showed a significant reduction in THC emissions. Both SME and PHSME B20 blends yielded small increases in NO sub(x) emissions. The reduction in double bond content of PHSME did not result in a statistically significant difference in NO sub(x) emissions versus SME at the B20 blend level. The test engine consumed a greater amount of fuel operating on the SME and PHSME blends than on neat ULSD, but the increase was smaller for the PHSME blend.

Cropping patterns in this region have changed considerably in recent years, with much greater acreages devoted to maize in areas historically planted to small grains. Considering that OBDV is endemic in small grains in this region and that its aster leafhopper vector (Macrosteles quadrilineatus) is commonly detected in maize, we questioned whether maize might be a host for OBDV. Although Westdal reported that maize was not a host for OBDV, it is the primary host for the related Maize rayado fino virus (MRFV) transmitted by Dalbulus maidis. MRFV is the type member of the marafiviruses and ranges from South America to the southern United States. To reevaluate the ability of maize to serve as a host for OBDV, viruliferous aster leafhoppers were allowed to feed on young maize seedlings for a 7-day inoculation access period. Plants were assayed for the presence of OBDV by ELISA 21 days after leafhopper removal. Initially, open-pollinated Sunglow sweet corn was tested in three experiments, with infection rates of 17 to 100%. A test of hybrid Sunglow resulted in 63% infection. These are comparable to transmission levels obtained when oat and barley plants are fed upon by viruliferous leafhoppers. Subsequently, 10 additional varieties of sweet and field corn were tested to determine if they could serve as hosts for OBDV. Sweet corn included Silver Queen, Peaches and Cream, Morning Star, Sugar Dots, Kandy Korn, and Golden Cross Bantam. Field corn included four lines provided by the maize breeding program of M. Carena at North Dakota State University (056640, 056643, 056612, and 056652). At least one plant was infected in all sweet and field corn varieties except 056612. Infected plants were largely asymptomatic, although a very faint stipple-striping was observed on some plants. To determine whether leafhoppers could acquire OBDV from infected maize and transmit the virus to other hosts, healthy leafhoppers were fed upon detached leaves of infected maize for 4 days (approximately 30 days after initial infection) and subsequently transferred three times at weekly intervals to barley and oats. Infection rates of 42 to 55% were observed in target plants, indicating efficient transmission from maize to other cereal hosts. The extent of natural infection of maize by OBDV or economic loss, if any, remains to be determined. This discovery extends the host range of OBDV to include maize and suggests that maize has the potential to serve as a natural reservoir for OBDV. The identification of hosts for known and new marafiviruses, such as those recently detected in citrus and grape, will expand our understanding of the ecology and epidemiology of viruses within this group.

Approximately 25% of the plants had coalescing, interveinal, chlorotic, whitish, necrotic or dark brown-to-purple necrotic spots on leaves. Symptomatic plants were scattered within the planting. Fifteen symptomatic plants were collected between March and May of 2008, and nucleic acid extracts were analyzed for ophiovirus infection by reverse transcription (RT)-PCR with ophiovi-rus-specific degenerate primers. The diagnostic 136-bp ophiovirus product from the RdRp gene was amplified from 14 of 15 freesia plants tested. A partially purified virus preparation was analyzed by transmission electron microscopy and potyvirus- and ophiovirus-like particles were detected. The potyviruses, Freesia mosaic virus (FreMV) and Bean yellow mosaic virus (BYMV), each cause mosaic symptoms, although BYMV may induce necrosis late in the season. RT-PCR performed on the same nucleic acid samples using potyvirus coat protein (CP)-specific degenerate primers D335 and U335 amplified the diagnostic 335-bp fragment from 2 of 15 plants. Cloned sequence from these plants was identified as FreMV. The ophiovirus CP gene was amplified by RT-PCR and cloned from two symptomatic freesia plants using primers FreSVf-CP-XhoI 5'-GACTCGAGAAATGTCTGGAAAATACTCTGTTC-3' and FreSVf-CP-BamHI 5'-CCAGGATCCTTAGATAGTGAATCCATAAGCTG-3', based on the sequence of Freesia sneak virus (FreSV) isolates from freesia (GenBank No. DQ885455) and lachenalia. The approximate 1.3-kb ampli-con was cloned and sequences of two cDNA clones were identical (GenBank No. FJ807730). The deduced amino acid sequence showed 99% identity with the Italian FreSV CP sequence (GenBank No. DQ885455), confirming FreSV in the symptomatic freesia plants. To our knowledge, this is the first report of FreSV in Virginia and the United States. Soilborne freesia leaf necrosis disease has been reported in Europe since the 1970s; several viral causal agents have been hypothesized but recent findings correlate best with the ophiovirus. In Virginia, the presence of FreSV, but not FreMV, was strongly correlated with the leaf necrosis syndrome. FreSV, likely soilborne through Olpidium brassicae, may pose a new soilborne threat for bulbous ornamentals, since it has been recently detected also in Lachenalia spp. (Hyacinthaceae) from South Africa. Although specific testing of O. brassicae was not performed, the disease may potentially persist in the soil for years in O. brassicae resting spores and development of symptoms may be affected by environmental conditions.

Chips and fries processed from infected tubers often develop brown discoloration, greatly reducing their marketability. At least seven distinct phytoplasma strains belonging to five different phytoplasma groups (16SrI, 16SrII, 16SrVI, 16SrXII, and 16SrXVIII) have been reported to cause purple top and related symptoms in potato. During an unusual drought in 2007, a newly emerging potato disease with extensive yellowish or reddish purple discoloration of terminal shoots and leaves, similar to PPT symptoms, was observed in isolated potato fields in Montana where over 50% of plants exhibited symptoms. Shoot tissues were collected from three symptomatic plants and 17 tubers randomly collected from 17 other symptomatic plants. The tubers were cold treated to induce sprouting and then planted in the greenhouse. All tubers produced plants of which seven exhibited PPT symptoms including severe stunting. Total nucleic acid was extracted from leaf veinal tissue, stolons, or tubers of 10 symptomatic and 10 asymptomatic plants (both field-collected and greenhouse samples) as previously described. A nested-PCR assay, using universal primer pair P1/16S-SR followed by R16F2n/R16R2n, was performed as previously described to detect phytoplasmas in these samples. Phytoplasma strains were detected in all symptomatic plants. Restriction fragment length polymorphism (RFLP) analyses of nested-PCR products (approximately 1.2 kb) with seven key restriction enzymes (AluI, MseI, HhaI, Tsp509I, HpaII, RsaI, and BfaI) indicated that all samples contained a very similar or identical phytoplasma most closely related to reference strain MW1 (belonging to subgroup 16SrIH-F). Analysis of cloned 16S rDNA sequences confirmed the identity of this new phytoplasma and sequences of three representative PPT-MT strains were deposited in GenBank with Accession Nos. FJ226074-FJ226076. Computer-simulated RFLP analyses of 1.2-kb 16S rDNA sequences of this new phytoplasma and representative members in the peach X-disease phytoplasma group (16SrIII) available in GenBank indicated the strain is distinct and represents a new subgroup, 16SrIII-M. This study also indicated that the phytoplasma is tuber transmissible since approximately 35% of plants produced from infected tubers collected in this study developed symptoms. Transmission via infected tubers may pose a potential threat for disease spread by planting uncertified seed potatoes. To our knowledge, this is the first report of 16SrIII group phytoplasmas-associated diseases in potato. A phytoplasma closely related to the PPT-MT strains has recently been detected in potato seedlings exhibiting purple top, rosette, and stunting in Alaska (GenBank Accession No. FJ376628).

Autumn months in wheat-growing regions typically experience significant rainfall. Hence, the wheat plants usually are exposed to freezing temperatures when they have high moisture content and are growing in very wet soil. Both of these conditions are conducive to freezing stresses different from those that occur under lower moisture conditions. This study was conducted to seek genetic variability among winter wheat lines and their progeny in the ability to tolerate freezing in saturated soil. Fully acclimated seedlings in saturated soil were frozen to a narrow range of temperature conditions that resulted in about 50% mortality of the most freezing tolerant lines studied. The temperature of the soil near the crowns of the plants was recorded every 2 min throughout each freezing episode. The following components were then determined for each freezing episode: the amount of time the plants remained in subfreezing temperature before all freezable water had been converted to ice; the rate of cooling from the freezing temperature to the minimum temperature; the minimum temperature; the length of time the plants remained at the minimum temperature; the rate of temperature increase from the minimum to 0 degree C after freezing; and the total amount of time the plants were actually frozen. Partial regression analysis revealed the minimum temperature significantly influenced survival in all of the progeny populations, while the other five components significantly influenced survival in some, but not all of the populations, suggesting genotypic differences in the ability to tolerate variation in specific aspects of the freezing process. Evidence from progeny populations suggested that improved freezing tolerance was associated with decreased sensitivity to the length of time held at the minimum temperature and increased responsiveness to the post- freezing warming rate. Further analysis of this kind of variation may enable the genetic combining of sources of tolerance of the stresses imposed by specific components of the freezing process, leading to cultivars with improved tolerance of freezing in saturated soil.

To determine how growth and sugar content have been altered by six cycles of recurrent selection for sucrose, five cultivars from the first generation (released from 1924 to 1933) were compared with five cultivars from the seventh generation (released from 2003 to 2007). In July of 2006 and 2007, we flagged 20 stalks per plot and marked the top internode that was just beginning to elongate. We then sampled one stalk per plot at weekly to biweekly intervals for 12 weeks. We measured stalk length and internode number, and the length, fresh weight, dry weight, water content, and sugar content of the marked internode. Stalks from the Generation 7 cultivars were taller, and had more internodes than those from Generation 1 cultivars. The marked internodes of Generation 7 and Generation 1 cultivars had similar elongation rates during early development, but elongation ended earlier in Generation 7 cultivars so that internodes of Generation 7 cultivars were shorter when fully elongated than those of Generation 1 cultivars. These shorter internodes had lower fresh weights, but similar dry weights as the longer Generation 1 internodes. Water content also decreased faster in Generation 7 than Generation 1 internodes. Generation 7 internodes had more total sugar and more sucrose throughout development. Generation 7 internodes also maintained a higher sucrose:total sugar ratio until the end of the sampling period. We conclude that recurrent selection for sucrose content in sugarcane has altered the allocation of photosynthate from growth to storage within the internode. This is possibly due to a change in the regulation of sucrose metabolism within the internode.

Cross-sectional survey conducted in 2344 households with children. The main exposure measure was food insecurity status, which was categorized as food secure or food insecure based on two or more food insecurity questions answered in the affirmative. Multiple logistic regression analysis was used to model the association between food insecurity status and selected child well-being indicators. Barbados, St. Lucia and St. Vincent and the Grenadines (hereafter St. Vincent), three Eastern Caribbean countries, 2005. A random sample of households with children was identified by the governments of Barbados, St. Lucia and St. Vincent. In-home interviews were conducted by social workers. One-third (33 %) of households were categorized as food insecure. Food-insecure households were more likely to include a chronically ill parent (OR = 2.48; 95 % CI 1.76, 3.49), a recently divorced parent (OR = 1.92; 95 % CI 1.21, 3.05), a child requiring multiple visits to a health-care provider for a disability (OR = 3.98; 95 % CI 1.20, 13.19) or injury (OR = 1.78; 95 % CI 1.12, 2.83), a child with a learning disability (OR = 2.08; 95 % CI 1.16, 3.74) or a child with a physical disability (OR = 2.54; 95 % CI 1.22, 5.32) after adjustment for poverty and other demographic variables. The results indicate that food-insecure households were more likely to be burdened by child disability (learning and physical), family system disruption (recent divorce and chronic illness) and child health-care needs (for disability and injury) than food-secure households. The implementation of programmes and policies to minimize food insecurity in the Eastern Caribbean may be warranted.

Results showed that d super(1) super(5)N-NO sub(3) super(-) and d super(1) super(8)O-NO sub(3) super(-) in precipitation varied significantly during individual storm events. Seasonally, d super(1) super(5)N-NO sub(3) super(-) and d super(1) super(8)O-NO sub(3) super(-) in precipitation followed a pattern of depletion during the summer months and enrichment during the winter months. NO sub(3) super(-) precursor concentrations and atmospheric oxidants were useful for explaining the seasonal and within-storm variation of d super(1) super(5)N-NO sub(3) super(-) for all six storm events as evidenced by negative relationships with NO sub(2):NO sub(x) ratios and ozone (O sub(3)). In comparison, d super(1) super(8)O-NO sub(3) super(-) was positively related to O sub(3) in three dormant season storms, which suggested that the O sub(3) oxidation pathway was important for producing the high d super(1) super(8)O-NO sub(3) super(-) observed in wintertime precipitation. Storm track information was especially useful for describing differences in d super(1) super(5)N-NO sub(3) super(-). Cool-sector storms originating from the E/NE produced slightly negative d super(1) super(5)N-NO sub(3) super(-) values characteristic of automobile emissions, whereas warm-sector storms with tracks from the SW/S/SE produced slightly positive d super(1) super(5)N-NO sub(3) super(-) values characteristic of coal-fired emissions. Lightning also may have been an important source of atmospheric NO sub(3) super(-) during two warm-sector thunderstorms. This study showed that (1) information about oxidant levels can be useful to predict the seasonal and within-storm variation of NO sub(3) super(-) stable isotopes in precipitation, and (2) knowledge of storm tracks (warm-sector versus cool-sector) may be important for determining sources of NO sub(3) super(-) in wet deposition.

To develop serological diagnostic tools for the detection of this virus, the production of good quality antibodies is a necessity. The coat protein (CP) gene of a California isolate of PZSV was cloned into a bacterial expression vector (pTriEX-4 Ek/LIC). The plasmid pTriEX-4-PZSV-CP was transformed into Escherichia coli Rosetta 2(DE3)pLacI and the recombinant PZSV-CP was expressed as a fusion protein containing N-terminal hexa-histidine and S tags. Expressed PZSV-CP was purified under denaturing conditions by affinity chromatography yielding 3mg refolded protein per 200mL of bacterial culture, and used as an antigen for raising PZSV-CP antiserum in rabbits. Specificity of the antiserum to PZSV was shown by Western blot and ELISA. When used in Western blot analysis, the antiserum was able to detect the recombinant protein, the PZSV coat protein and PZSV infected plant samples. The antiserum was successfully used in indirect-ELISA at dilutions of up to 1:16,000 to detect PZSV in infected leaf samples. Direct ELISA was successful only with denatured antigens. This is the first report on production of polyclonal antiserum against recombinant coat protein of PZSV and its use for detection and diagnosis of virus using serological methods.

The influence of the percentage of corn, Z. mays L., cotton, rice, Oryza sativa L., soybean, Glycine max L., and non-crop land within a 0.4 km buffer surrounding a cotton field and populations of heliothine eggs and tarnished plant bugs in cotton were examined over a three-year period. There was a positive relationship between the area in corn, Zea mays L., within 0.4 km of cotton fields and numbers of heliothine eggs in cotton in June 2004 and 2005. Positive relationships were observed between numbers of tarnished plant bugs in cotton and the surrounding area planted to corn, while negative relationships were observed for the area planted to cotton. Cotton fields with earlier dates of first flower had greater overall populations of tarnished plant bugs. Distributions of all three pests in cotton were at least partially explained by the time of year and the type of crop within the local environment. This indicates that more detailed spatial information and historical records may have value for managing cotton insects across large farms or communities.

However, little is known about the effect of green tea on immune function. In this study we determined the effect of epigallocatechin-3-gallate (EGCG), the major active component of tea, on proliferation of spleen cells isolated from C57BL mice. Results showed that T cell proliferation was inhibited by EGCG at physiologically relevant concentrations of 2.5 to 10 kM. EGCG at these concentrations did not induce cytotoxicity or apoptosis. Oxidative stress is not likely to be responsible for the EGCG- induced suppression of T cell proliferation because H sub(2)O sub(2) generation was not significantly different between the cultures supplemented with 1 to 10 kM EGCG and control and catalase did not prevent this EGCG- induced inhibition. Further mechanistic studies showed that EGCG dose dependently inhibited T cell division and cell cycle progression. EGCG supplementation resulted in lower IL-2 receptor expression and higher IL-2 accumulation, suggesting an impeded IL-2/IL-2 receptor signaling. These results indicate that EGCG supplementation may be beneficial to those with abnormally excessive T cell function such as autoimmune and inflammatory disorders, but caution should be taken when it is administered at high doses to those with compromised T cell function.

However, monitoring spatial Kcb at sufficient temporal resolution using only aerial acquisitions would likely not be cost-effective for growers. In this study, we evaluated a model-based sampling approach, ESAP (EC sub(e) Sampling, Assessment, and Prediction), aimed at reducing the number of seasonal aerial images needed for reliable Kcb monitoring. Aerial imagery of NDVI was acquired over an experimental cotton field having two treatments of irrigation scheduling, three plant density levels, and two N levels. During both 2002 and 2003, ESAP software used input imagery of NDVI on three separate dates to select three ground sampling designs having 6, 12, and 20 sampling locations. On three subsequent dates during both the years, NDVI data obtained at the design locations were then used to predict the spatial distribution of NDVI for the entire field. Regression of predicted versus imagery observed NDVI resulted in r super(2) values from 0.48 to 0.75 over the six dates, where higher r super(2) values occurred for predictions made near full cotton cover than those made at partial cover. Prediction results for NDVI were generally similar for all three sample designs. Cumulative transpiration (Tr) for periods from 14 to 28 days was calculated for treatment plots using Kcb values estimated from NDVI. Estimated cumulative Tr using either observed NDVI from imagery or predicted NDVI from ESAP procedures compared favorably with measured cumulative Tr determined from soil water balance measurements for each treatment plot. Except during late season cotton senescence, errors in estimated cumulative Tr were between 3.0% and 7.3% using observed NDVI, whereas they were they were between 3.4% and 8.8% using ESAP-predicted NDVI with the 12 sample design. Thus, employing a few seasonal aerial acquisitions made in conjunction with NDVI measurements at 20 or less ground locations optimally determined using ESAP, could provide a cost-effective method for reliably estimating the spatial distribution of crop water use, thereby improving cotton irrigation scheduling and management.

The Environmental Policy Integrated Climate (EPIC) model was used to evaluate its application as a decision support tool for irrigation management of cotton and maize under South Texas conditions. Simulation of the model was performed to determine crop yield, crop water use, and the relationships between the yield and crop water use parameters such as crop evapotranspiration (ETc) and water use efficiency (WUE). We measured actual ETc using a weighing lysimeter and crop yields by field sampling, and then calibrated the model. The measured variables were compared with simulated variables using EPIC. Simulated ETc agreed with the lysimeter, in general, but some simulated ETc were biased compared with measured ETc. EPIC also simulated the variability in crop yields at different irrigation regimes. Furthermore, EPIC was used to simulate yield responses at various irrigation regimes with farm fields' data. Maize required ~700mm of water input and ~650mm of ETc to achieve a maximum yield of 8.5Mgha super(-) super(1) while cotton required between 700 and 900mm of water input and between 650 and 750mm of ETc to achieve a maximum yield of 2.0-2.5Mgha super(-) super(1). The simulation results demonstrate that the EPIC model can be used as a decision support tool for the crops under full and deficit irrigation conditions in South Texas. EPIC appears to be effective in making long-term and pre-season decisions for irrigation management of crops, while reference ET and phenologically based crop coefficients can be used for in-season irrigation management.

Well determined thermal properties of compost feedstocks will therefore contribute to practical thermodynamic approaches. Thermal conductivity, thermal diffusivity, and volumetric heat capacity of 12 compost bulking materials were determined in this study. Thermal properties were determined at varying bulk densities (1, 1.3, 1.7, 2.5, and 5 times uncompacted bulk density), particle sizes (ground and bulk), and water contents (0, 20, 50, 80% of water holding capacity and saturated condition). For the water content at 80% of water holding capacity, saw dust, soil compost blend, beef manure, and turkey litter showed the highest thermal conductivity (K) and volumetric heat capacity (C) (K: 0.12-0.81 W/m °C and C: 1.36-4.08 MJ/m3 °C). Silage showed medium values at the same water content (K: 0.09-0.47 W/m °C and C: 0.93-3.09 MJ/m3 °C). Wheat straw, oat straw, soybean straw, cornstalks, alfalfa hay, and wood shavings produced the lowest K and C values (K: 0.03-0.30 W/m °C and C: 0.26-3.45 MJ/m3 °C). Thermal conductivity and volumetric heat capacity showed a linear relationship with moisture content and bulk density, while thermal diffusivity showed a nonlinear relationship. Since the water, air, and solid materials have their own specific thermal property values, thermal properties of compost bulking materials vary with the rate of those three components by changing water content, bulk density, and particle size. The degree of saturation was used to represent the interaction between volumes of water, air, and solids under the various combinations of moisture content, bulk density, and particle size. The first order regression models developed in this paper represent the relationship between degree of saturation and volumetric heat capacity (r = 0.95-0.99) and thermal conductivity (r = 0.84-0.99) well. Improved knowledge of the thermal properties of compost bulking materials can contribute to improved thermodynamic modeling and heat management of composting processes.

After the initial incubation series, methane production was reduced greater than 92% from that of non-treated controls (25.8 ± 8.1 mmol ml-1 incubation fluid) in cultures treated with nitroethane, sodium laurate, Lauricidin(r) or a finely-ground product of the marine algae, Chaetoceros (added at 1, 5, 5 and 10 mg ml-1, respectively) but not in cultures treated with sodium nitrate (1 mg m1-1). Methane production during two successive incubations was reduced greater than 98% from controls (22.5 ± 3.2 and 23.5 ± 7.9 mmol ml-1, respectively) by all treatments. Reductions in amounts of volatile fatty acids and ammonia produced and amounts of hexose fermented, when observed, were most severe in sodium laurate-treated cultures. These results demonstrate that all tested compounds inhibited ruminal methane production in our in vitro system but their effects on fermentation differed.

Increased CO sub(2) concentrations and temperatures significantly (P < 0.05) enhanced microbial reduction. A maximum reduction of 5.8-log was obtained at 8.2% CO sub(2) and 42 C. To achieve a 5-log reduction of E. coli K12 in 0.1% buffered peptone water, minimum CO sub(2) concentrations of 9.5%, 5.5%, and 5.3% were needed at 34, 38, and 42 C, respectively. Further reductions of cells were observed after storage for 7 days at 4 C. But storage at 25 C increased the number of viable cells to 8-log cfu/mL after 7 days. This study showed the potential of the pilot scale SCCO sub(2) system with a gas-liquid porous metal contactor for microbial inactivation in liquid food.

This study was conducted to develop a laboratory system for simultaneous investigation of surface and subsurface hydrologic and nutrient dynamics within a soil block. The system consists of a square steel casing 61 cm wide and long by 61 cm deep that is driven into the ground with a 1.1 Mg drop hammer, excavated, and undergirded with a 12.7 mm thick PVC plate to capture an undisturbed soil block Unique features of the lysimeter system include the use of petrolatum (petroleum jelly) to suppress side wall bypass flow and potential chemical interaction with the steel lysimeter walls, and the capability to investigate overland and subsurface flows in one assemblage.

The STEWARDS application is GIS-based and couples temporal and spatial aspects of data collected from each site within a watershed. The STEWARDS database and software design accommodates research data with heterogeneous characteristics and format, and captures rich descriptive information that is important to understand the data from complex, dynamic research programs. The database includes soil, water, climate, land management, and socio-economic data from multiple watersheds across the U.S. and can provide data commonly needed for hydrologic modeling and assessments. The release of STEWARDS marks an advance in the research capacity for the ARS research watershed network by improving access to well-documented and consistently organized data and is becoming the prototype of additional data and software designs for other ARS research projects.

A two-dimensional, grid-based model has been developed to compute soil redistribution and morphological changes of complex landscapes due to tillage operations. Soil movement along and perpendicular to the directions of tractor movement are computed as a function of local slope gradients and of characteristics of the tillage implement. A control volume approach is employed to determine terrain elevation changes after each tillage pass. The model explicitly considers the presence of internal and external field boundaries, simulating their influence on the development of erosion and deposition patterns. GIS layers are used to provide terrain elevation data, actual tillage directions, field borders, and the location of other features, such as vegetated strips, trees, or fences. The model was verified against an analytical solution for the development of bench terraces due to tillage between vegetated strips. The model's capability of considering variable tillage directions was tested with a simulation of tillage erosion over a synthetic, undulating surface and was used to investigate how an implement's forward and lateral soil displacement characteristics influence erosion patterns as a function of tillage direction relative to slope. The model's stability, computational efficiency, and ability to simulate fields with complex boundaries and varying tillage directions allow its use as a practical tool within a comprehensive conservation planning system.

It is intended to isolate metal canisters with highly radioactive waste products from the surrounding rocks because of its ability to retard the movement of radionuclides by adsorption. Slovak Republic avails of many significant deposits of bentonites. Adsorption of Cs on five Slovak bentonites of deposits (Jelsovy potok, Kopernica, Lieskovec, Lastovce and Dolna Ves) has been studied with the use of batch technique. In the case of Dolna Ves deposit, the mixed-layer illite--smectite has been identified as the main clay component. Natural and irradiated samples, in two different kinds of grain size: 45 and 250 *mm have been used in the experiments. The adsorptions of Cs on bentonite under various experimental conditions, such as contact time, adsorbent and adsorbate concentrations have been studied. The Cation Exchange Capacity values for particular deposits drop in the following order: Jelsovy potok > Kopernica > Lieskovec > Lastovce > Dolna Ves. Bentonites irradiated samples with 390 kGy have shown higher specific surface and higher values of the adsorption capacity. Distribution coefficients have been determined for bentonite-cesium solution system as a function of contact time and adsorbate and adsorbent concentration. The data have been interpreted in terms of Langmuir isotherm. The uptake of Cs has been rapid and the adsorption of cesium has increased with increasing metal concentrations. The adsorption percentage has decreased with increasing of metal concentrations. Adsorption of Cs has been suppressed by presence of Ca more than Na cation. Sorption experiments carried out show that the most suitable materials intended for use as barriers surrounding a canister of spent nuclear fuel are bentonites of the Jelsovy potok and Kopernica deposits.

If this crop type information could be obtained accurately from remote sensing data, the effort required would be significantly reduced, especially for large watersheds. The objective of this study was to compare two methods using multiple satellite remote sensing datasets to differentiate land cover, including crop type, for the Salt River/Mark Twain Lake basin in northeast Missouri. Method 1 involved unsupervised classification of Landsat visible and near-infrared satellite images obtained at multiple dates in the growing season, followed by traditional, manual class identification. Method 2, developed in this research, employed the same unsupervised classification but also used normalized difference vegetation index (NDVI) maps obtained on a 16-day cycle from MODIS satellite images as ancillary data to derive seasonal NDVI trends for each class in the classification map. Tree analysis was applied to the NDVI trend data to group similar classes into clusters, and crop type for each cluster was determined from ground-truth data. Additional ground-truth data were used to assess the accuracy of the procedure, and crop acreage estimates were compared to county-level statistics. The overall classification accuracy of Method 2 was 3% higher than that of Method 1. Method 2 was also more efficient in terms of analyst time and ground-truth data requirements. Therefore, this method, employing variations in seasonal NDVI trends, is suggested for differentiation of crop type. The 30-m resolution crop type maps developed using this process will be useful as input data to environmental analysis models.

However, problems and regulations on environmental issues, mandatory stocking of 100% native North American salmon, and disease have impacted economic viability of the U.S. salmon industry. In response to these problems, the USDA ARS developed the National Cold Water Marine Aquaculture Center (NCWMAC) in Franklin, Maine. The NCWMAC is adjacent to the University of Maine Center for Cooperative Aquaculture Research on the shore of Taunton Bay and shares essential infrastructure to maximize efficiency. Facilities are used to conduct research on Atlantic salmon and other cold water marine finfish species. The initial research focus for the Franklin location is to develop a comprehensive Atlantic salmon breeding program from native North American fish stocks leading to the development and release of genetically improved salmon to commercial producers. The Franklin location has unique ground water resources to supply freshwater, brackish water, salt water or filtered seawater to fish culture tanks. Research facilities include office space, primary and secondary hygiene rooms, and research tank bays for culturing 200+ Atlantic salmon families with incubation, parr, smolt, on-grow, and broodstock tanks. Tank sizes are 0.14m super(3) for parr, 9m super(3) for smolts, and 36, 46 and 90m super(3) for subadults and broodfish. Culture tanks are equipped with recirculating systems utilizing biological (fluidized sand) filtration, carbon dioxide stripping, supplemental oxygenation and ozonation, and ultraviolet sterilization. Water from the research facility discharges into a wastewater treatment building and passes through micro-screen drum filtration, an inclined traveling belt screen to exclude all eggs or fish from the discharge, and UV irradiation to disinfect the water. The facility was completed in June 2007, and all water used in the facility has been from groundwater sources. Mean facility discharge has been approximately 0.50m super(3)/min (130gpm). The facility was designed for stocking densities of 20-47kg/m super(3) and a maximum biomass of 26,000kg. The maximum system density obtained from June 2007 through January 2008 has approached 40kg/m super(3), maximum facility biomass was 11,021kg, water exchange rates have typically been 2-3% of the recirculating system flow rate, and tank temperatures have ranged from a high of 15.4 super(o)C in July to a low of 6.6 super(o)C in January 2008 without supplemental heating or cooling.

To evaluate the risk of resistance evolution and to develop a better resistance management strategy, a field-collected population was selected with tebufenozide in the laboratory. Thereafter, the inheritance and fitness cost of tebufenozide resistance in S. exigua were investigated. RESULTS: After being selected with tebufenozide for 61 generations, S. exigua developed a 92-fold resistance to the chemical. The degrees of dominance for the reciprocal cross progeny were - 0.2698 and - 0.2785. The resistant strain had a relative fitness of 0.71, with substantially lower rates of larval survival, pupal weight, pupation and oviposition per female, and prolonged larval and pupal duration. PBO significantly increased the toxicity of tebufenozide (SR = 2) against resistant insects, and DEM and DEF also showed synergism with tebufenozide. CONCLUSION: Tebufenozide resistance in S. exigua was inherited as autosomal, incompletely recessive and controlled by more than one gene. Development of the resistance may cost significant fitness for the resistant population. Mixed-function oxidases might play an important role in tebufenozide resistance in S. exigua. This study provided valuable information for further understanding tebufenozide resistance and for facilitating the development of resistance management strategies.

Yet key elements of a national observation network are lacking or at risk. A U.S. National Research Council review of the U.S. Climate Change Science Program earlier this year highlighted the critical need for a U.S. climate observing system to meet requirements of mitigation policies for improved carbon cycle observations. This Forum highlights the most significant gaps and threats to carbon cycle observations--including observations from satellites; in situ observations of land, ocean, and aquatic systems; and direct atmospheric measurements--and suggests ways to improve the U.S. national effort.

AN - 67552666; 19616216 AB - This work deals with simultaneous determination of ammonium, calcium, magnesium, sodium and potassium in drinking waters by capillary zone electrophoresis (CZE) on a column-coupling (CC) chip with suppressed hydrodynamic and electroosmotic transports. CZE separations were carried out in a propionate background electrolyte at a low pH (3.2) containing 18-crown-6-ether (18-crown-6) to reach a complete resolution of the cations. In addition, triethylenetetramine (TETA) coated the inner wall surface of the chip channels. The concentration limits of detection (cLOD) for the studied cations ranged from 4.9 to 11.5 microg/l concentrations using a 900 nl volume of the sample injection channel. 93-106% recoveries of the cations in drinking waters indicate a good predisposition of the present method to provide accurate analytical results.

We studied foliage characteristics and leaf-level photosynthesis on 7-year-old European beech (Fagus sylvatica) and pedunculate oak (Quercus robur) regeneration established in open patches and shelterwoods of a partially harvested Norway spruce plantation in southwestern Sweden. Both species exhibited morphological plasticity at the leaf level by developing leaf blades in patches with an average mass per unit area (LMA) 54% greater than of those in shelterwoods, and at the plant level by maintaining a leaf area ratio (LAR) in shelterwoods that was 78% greater than in patches. However, we observed interspecific differences in photosynthetic capacity relative to spruce canopy openness. Photosynthetic capacity (A sub(1) sub(6) sub(0) sub(0), net photosynthesis at a photosynthetic photon flux density of 1600kmolphotonsm super(-) super(2)s super(-) super(1)) of beech in respect to the canopy gradient was best related to leaf mass, and declined substantially with increasing canopy openness primarily because leaf nitrogen (N) in this species decreased about 0.9mgg super(-) super(1) with each 10% rise in canopy openness. In contrast, A sub(1) sub(6) sub(0) sub(0) of oak showed a weak response to mass-based N, and furthermore the percentage of N remained constant in oak leaf tissues across the canopy gradient. Therefore, oak photosynthetic capacity along the canopy gradient was best related to leaf area, and increased as the spruce canopy thinned primarily because LMA rose 8.6gm super(-) super(2) for each 10% increase in canopy openness. These findings support the premise that spruce stand structure regulates photosynthetic capacity of beech through processes that determine N status of this species; leaf N (mass basis) was greatest under relatively closed spruce canopies where leaves apparently acclimate by enhancing light harvesting mechanisms. Spruce stand structure regulates photosynthetic capacity of oak through processes that control LMA; LMA was greatest under open spruce canopies of high light availability where leaves apparently acclimate by enhancing CO sub(2) fixation mechanisms.

Variable winds are often cited as the cause of high heterogeneity in snow distribution in non-forested mountain locations. Distributed models capable of capturing the variability in these fluxes require a time series of distributed wind data at a comparably fine spatial scale. Application of atmospheric and surface wind flow models in these regions has been limited by our ability to represent this complex process in a computationally efficient manner. Simplified models based on terrain and vegetation parameters are not as explicit as more complex, fluid-flow models, but are computationally efficient for real-time operational use. We developed and applied a simplified wind model based on analysis of upwind terrain to predict wind speeds across diverse topographies at three mountainous research locations. Each site was instrumented with a network of wind sensors to capture the full range of wind variability present. Differences in upwind topography were significantly related (p < 0DT0001) to wind-speed differences between sites. Wind speeds at each sensor location were modelled from each of the other intra-site locations as if data from only one sensor were available. The wind model explained 69% of the observed variance with a mean absolute prediction error of 0DT8 m/s, 19% of the observed wind mean. These results were very encouraging given the inherent complexity and profound variability of processes determining wind patterns in these systems.

A large subset harbors C-terminal SH3b_5 cell wall binding domains. These C-terminal domains have been shown to be necessary for accurate cell wall recognition and subsequent staphylolytic activity for some endolysins. Over fifty proteins of staphylococcal or phage origin containing SH3b domains were aligned, yielding five highly repetitive groups of proteins. Representative C-termini from these five groups, and six staphylococcal proteins for which no homologues have been identified, were aligned, revealing two distinct SH3b_5 subgroups with overlapping but differentially conserved residues. A premise behind this research is that there may be unique cell wall binding properties conferred by these staphylococcal domains that could be exploited to specifically enhance anti-staphylococcal efficacy in heterologous protein fusion constructs. To identify functional differences between the two subgroups, the native Cpl-7 cell wall binding domains of the streptococcal LambdaSa2 endolysin were replaced by staphylococcal SH3b domains from both subgroups. SH3b domains from either lysostaphin (bacteriocin) or LysK (phage endolysin) resulted in a 5x increase in staphylolytic activity conferred on the streptococcal endopeptidase domain, and surprisingly these same fusions maintained significant streptolytic activity suggesting that the staphylococcal SH3b domains are not always staphylococcal-specific. A comparison of the differences in lytic activity conferred on the LambdaSa2 endopeptidase domain by either LysK or lysostaphin SH3b domain differed by no more than a factor of two.

Farms with PDD-afflicted cows experience economic loss due to treatment costs, decreased milk production, lower reproductive efficiency and premature culling. Cows exhibit both humoral and cellular immune responses to PDD-associated spirochetes. This study was undertaken to further characterize the bovine humoral response to PDD-associated spirochetes. Forty-seven sera samples collected from cattle (Field cattle) on three different dairy operations in Iowa were analyzed. In addition, sera were obtained from six young steers (Test cattle) that received a mixed inoculum of four previously isolated Treponema phagedenis-like spirochetes (1A, 3A, 4A and 5B) on two separate occasions. Relative levels of total IgG, IgG1, IgG2 and IgM reactive to each individual spirochete were determined. Field cattle had a higher mean antibody response to 5B compared to the other isolates and T. phagedenis. Test cattle reacted most strongly with 4A following initial exposure, shifting to a greater reactivity with 5B and a reactivity profile similar to field cattle following secondary exposure. No measurable IgM was detected. IgG1 was produced predominately in all cattle. Low to moderate levels of total IgG reactivity to T. phagedenis occurred with sera from all cattle.

To better understand the effect of iron availability on soybean yield, we identified genes in two near isogenic lines with changes in expression patterns when plants were grown in iron sufficient and iron deficient conditions. Transcriptional profiles of soybean (Glycine max, L. Merr) near isogenic lines Clark (PI548553, iron efficient) and IsoClark (PI547430, iron inefficient) grown under Fe-sufficient and Fe-limited conditions were analyzed and compared using the Affymetrix+ GeneChip+ Soybean Genome Array. There were 835 candidate genes in the Clark (PI548553) genotype and 200 candidate genes in the IsoClark (PI547430) genotype putatively involved in soybean's iron stress response. Of these candidate genes, fifty-eight genes in the Clark genotype were identified with a genetic location within known iron efficiency QTL and 21 in the IsoClark genotype. The arrays also identified 170 single feature polymorphisms (SFPs) specific to either Clark or IsoClark. A sliding window analysis of the microarray data and the 7X genome assembly coupled with an iterative model of the data showed the candidate genes are clustered in the genome. An analysis of 5' untranslated regions in the promoter of candidate genes identified 11 conserved motifs in 248 differentially expressed genes, all from the Clark genotype, representing 129 clusters identified earlier, confirming the cluster analysis results. These analyses have identified the first genes with expression patterns that are affected by iron stress and are located within QTL specific to iron deficiency stress. The genetic location and promoter motif analysis results support the hypothesis that the differentially expressed genes are co-regulated. The combined results of all analyses lead us to postulate iron inefficiency in soybean is a result of a mutation in a transcription factor(s), which controls the expression of genes required in inducing an iron stress response.

The percentage of retained colloids in column experiments decreased with Ci at intermediate IS conditions (31 or 56 mM) when colloids were weakly associated with the solid phase by a shallow secondary energy minima. In contrast, the effects of Ci on colloid retention were absent when IS was too low (6 mM) or too high (106 mM). The concentration effects under intermediate IS conditions were dependent on the system hydrodynamics, magnitude of Ci, and injection order of Ci, but they were largely independent of the input colloid mass. These observations were explained in part by time- and concentration-dependent filling of retention sites. Only a small fraction of the solid surface area was found to contribute to retention when IS was 31 mM, and micromodel observations indicated that colloid retention was enhanced in lower velocity regions of the pore space that occurred near grain-grain contacts. Consequently, retention profiles for IS = 31 mM conditions were increasingly nonexponential at lower values of Ci (during filling), whereas the observed concentration effect was largely eliminated as retention locations became filled. In addition, micromodel observations indicated that liquid and solid phase mass transfer of colloids to retention locations was influenced by Ci under intermediate IS conditions. Higher values of Ci are expected to produce less relative mass transfer to retention locations due to increased numbers of collisions that knock weakly associated colloids off the solid phase. Hence, the concentration effects were found to be largely independent of input colloid mass during filling of retention sites.

We propose modifying the Van Wagner crown fire propagation model, used to estimate the critical rate of spread necessary to sustain active crown fire, to use foliar biomass per square metre instead of canopy bulk density as the fuel input. We tested the efficacy of our proposed model by comparing predictions of crown fire propagation with Van Wagner's original data. Our proposed model correctly predicted each instance of crown fire presented in the seminal study. We then tested the proposed model for statistical equivalence to the original Van Wagner model using two contemporary techniques to parameterize canopy bulk density. We found the proposed and original models to be statistically equivalent when canopy bulk density was parameterized using the method incorporated in the Fire and Fuels Extension to the Forest Vegetation Simulator (difference < 0.5 km h super(-1), a = 0.05, n = 2626), but not when parameterized using the method of Cruz and others. Use of foliar biomass per unit area in the proposed model makes for more accurate and easily obtained fuel estimates without sacrificing the utility of the Van Wagner model.

The procedure permits development of daily maps that forecast, for the forthcoming week and within federal lands, percentiles of the distributions of (i) number of ignitions; (ii) number of fires above a given size; (iii) conditional probabilities of fires greater than a specified size, given ignition. As an illustration, we used the methods to study the skill of the Fire Potential Index - an index that incorporates satellite and surface observations to map fire potential at a national scale - in forecasting distributions of large fires.

For conventional practice, housekeeping genes have been applied as internal reference for data normalization and analysis since the technology appeared. However, housekeeping genes vary under different conditions and environmental stimuli and no commonly accepted housekeeping gene references are available. Accurate data acquisition and data reproducibility remain challenging and it is difficult to compare results from different experimental sources. Using yeast and a Fusarium fungus as examples, we demonstrate the independent performance of a sole reference gene, CAB, designated as a constant manual threshold for data acquisition, normalization, and analysis for multiple plate reactions. A robust master equation based on the CAB reference and the set of calibration control genes thereafter was established to estimate mRNA abundance for the same RNA background reactions. A valid range of amplification efficiency between 95% and 100% was observed for the control genes in different RNA background applied on an ABI real time PCR 7500 system. This newly developed robust quality control system provides a reliable means for absolute quantification of mRNA using the qRT-PCR, simplifies the conventional qRT-PCR procedures, and increases data reliability, reproducibility, and throughput of the assay.

We crossed 25 diverse inbred maize lines to the B73 reference line, capturing a total of 136,000 recombination events. Variation for recombination frequencies was observed among families, influenced by local (cis) genetic variation. We identified evidence for numerous minor single- locus effects but little two-locus linkage disequilibrium or segregation distortion, which indicated a limited role for genes with large effects and epistatic interactions on fitness. We observed excess residual heterozygosity in pericentromeric regions, which suggested that selection in inbred lines has been less efficient in these regions because of reduced recombination frequency. This implies that pericentromeric regions may contribute disproportionally to heterosis.

AN - 85413497; pmid-19831106 AB - Cognitive and mood decrements resulting from mild dehydration and glucose consumption were studied. Men and women (total N = 54; M age = 19.8 yr., SD = 1.2) were recruited from college athletic teams. Euhydration or dehydration was achieved by athletes completing team practices with or without water replacement. Dehydration was associated with higher thirst and negative mood ratings as well as better Digit Span performance. Participants showed better Vigilance Attention with euhydration. Hydration status and athlete's sex interacted with performance on Choice Reaction Time and Vigilance Attention. In a second study, half of the athletes received glucose prior to cognitive testing.

These studies were conducted to determine the compatibility of M. anisopliae (F52) with a wide range of fungicides commonly applied to container-grown ornamentals for the management of soil-borne plant pathogens. The impact of fungicides on spore germination and mycelial growth were determined in vitro. In addition, M. anisopliae persistence in bulk and rhizosphere soil was determined 30 days following dual application of each fungicide at 7--28 days intervals as prescribed. A number of fungicides (thiophanate-methyl, dimethomorph, captan, triflumizole, triflozystrobin, pyraclostrobin, azoxystrobin) inhibited spore germination in vitro. A larger number of fungicides (fosetyl-AI, thiophanate-methyl, dimethomorph, captan, quintozene, triflumizole, fludioxanil, triflozystrobin, pyraclostrobin, fludiox-mefanox, iprodione, azoxystrobin, phosphorus acid/K-salts) inhibited mycelial growth in vitro. Only three fungicides (etridiazole, propamocard and mafanoxam) had no significant impact in vitro on spore germination or mycelial growth. While a number of fungicides had a detrimental impact in vitro, there was no impact on M. anisopliae populations in bulk soil following dual application of any fungicide. However, the fungicides captan and triflumizolet, which have a short reapplication interval, had a detrimental impact on M. anisopliae populations in the rhizosphere. As researchers develop rhizosphere competence as an alternative management strategy for black vine weevil, the fungicides captan and triflumizole should be avoided.

Twenty U.S. commercial processing plants representing eight integrators in 13 states were included in the survey. In each of four replications, 10 carcasses from one flock were collected at rehang and 10 more carcasses were collected at postchill; each carcass was sampled by whole-carcass rinse. Salmonella organisms were isolated from carcass rinses by standard cultural techniques, serotypes were determined, and the resistance to 15 antimicrobials was measured. Overall, Salmonella was detected on 72% of carcasses at rehang (ranging from 35 to 97%) and on 20% of carcasses postchill (ranging from 2.5 to 60%). In every instance, a significant (P < 0.05) decrease in Salmonella prevalence was noted between rehang and postchill. The four most common serotypes, accounting for 64% of all Salmonella isolates, were Kentucky, Heidelberg, Typhimurium, and Typhimurium var. 5-; most isolates of Kentucky (52%), Heidelberg (79%), and Typhimurium (54%) serotypes were susceptible to all antimicrobial drugs tested. However, only 15% of the Typhimurium var. 5- isolates were pansusceptible; more than one-half of the isolates of this serotype were resistant to three or more drugs. No isolate of any serotype exhibited resistance to amikacin, ceftriaxone, ciprofloxacin, or trimethoprim-sulfamethoxazole. These data demonstrate that although processing lessens carcass contamination with Salmonella, antimicrobial-resistant isolates may still be present.

Campylobacter species are carried in the intestinal tracts of mammals and birds, and sources of human infection include raw milk, contaminated water, direct contact with pets, and foods, particularly poultry. Campylobacter jejuni and C. coli are the species that account for the majority of human infections. The aim of this work was to determine the prevalence of Campylobacter in 190 poultry carcasses sampled at slaughter and to use a multiplex PCR assay to determine if the isolates were C. jejuni or C. coli. C. coli was not isolated, while C. jejuni was recovered from 52 (37.1%) of 140 carcasses for which pools of four sampling sites (neck, cloaca, breast, and back) were examined. In the remaining 50 carcasses, the four sites were analyzed separately, and C. jejuni was recovered from the samples in the following order: neck (n = 20), cloaca (n = 16), breast (n = 14), and back (n = 11). The results are in agreement with those of other studies, which showed that C. jejuni is more commonly associated with poultry than is C. coli. Control strategies for Campylobacter should include interventions to eliminate C. jejuni in poultry at various stages of production and processing, including at slaughter.

AN - 734034297; 19723218 AB - Thermal preservation is used by the egg industry to ensure the microbiological safety of liquid egg white (LEW); however, it does not eliminate all microorganisms and impairs some of the delicate functional properties of LEW. In this study, a pilot-scale cross-flow microfiltration (MF) process was designed to remove the natural microflora present in commercial LEW, obtained from a local egg-breaking plant, while maintaining the nutritional and functional properties of the LEW. LEW, containing approximately 10(6 +/- 1.7) colony forming units (CFU) per milliliter of total aerobic bacteria, was microfiltered using a ceramic membrane with a nominal pore size of 1.4 microm, at a cross-flow velocity of 6 m/s. To facilitate MF, LEW was screened, homogenized, and then diluted (1 : 2, w/w) with distilled water containing 0.5% sodium chloride. Homogenized LEW was found to have a threefold lower viscosity than unhomogenized LEW. Influence of MF temperature (25 and 40 degrees C) and pH (6 and 9) on permeate flux, transmission of egg white nutrients across the membrane, and microbial removal efficiency were evaluated. The pH had a significantly greater influence on permeate flux than temperature. Permeate flux increased by almost 148% when pH of LEW was adjusted from pH 9 to pH 6 at 40 degrees C. Influence of temperature on permeate flux, at a constant pH, however, was found to be inconclusive. Microbial removal efficiency was at least 5 log(10) CFU/mL. Total protein and SDS-PAGE analysis indicated that this MF process did not alter the protein composition of the permeate, compared to that of the feed LEW, and that the foaming properties of LEW were retained in the postfiltered samples.

AN - 733576199; 19650735 AB - From 1998-2002 twenty-five deer self-treatment devices (4-Posters), using 2% amitraz, were operated at three locations in Maryland to determine their effectiveness in controlling blacklegged ticks, Ixodes scapularis Say, and lone star ticks, Amblyomma americanum (L.). Each treatment site was approximately 518 ha and paired with a similar site lacking 4-Posters. Locations varied in deer density, tick abundance, and land use. Flagging for host-seeking ticks showed declines in tick populations at all treatment sites compared to control sites by the third year. By 2002, control of I. scapularis nymphs attributable to the 4-Poster intervention at the three sites was 69.0%, 75.8%, and 80%. Control of A. americanum nymphs at the two sites where they occurred was 99.5% and 95.3%. In 2003, the first posttreatment year, control of I. scapularis remained around 2001-2002 levels, but by 2004, an upward trend in nymphal numbers was detectable. Populations of A. americanum showed no increase posttreatment. These results demonstrate that control of these tick species is locally possible with 4-Poster intervention.

AN - 67647245; 19736786 AB - Manual sampling of insects in stored grain is a laborious and time-consuming process. Automation of grain sampling should help to increase the adoption of stored grain integrated pest management. A new commercial electronic grain probe trap (OPI Insector) has recently been marketed. We field tested OPI Insector electronic grain probes in two bins, each containing 32.6 tonnes of wheat, Triticum aestivum L., over a 2-yr period. We developed new statistical models to convert Insector catch into insects per kilogram. We compared grain sample estimates of insect density (insects per kilogram of wheat) taken near each Insector to the model-predicted insect density by using Insector counts. An existing expert system, Stored Grain Advisor Pro, was modified to automatically read the Insector database and use the appropriate model to estimate Cryptolestes ferrugineus (Stephens), Rhyzopertha dominica (F.), and Tribolium castaneum (Herbst) density from trap catch counts. Management decisions using Insector trap-catch estimates for insect density were similar to those made using grain sample estimates of insect density for most sampling dates. However, because of the similarity in size of R. dominica and T. castaneum, the software was unable to differentiate counts between these two species. In the central and southern portions of the United States, where both species frequently occur, it may be necessary to determine the proportion of each species present in the grain by manual inspection of trap catch. The combination of SGA Pro with the OPI Insector system should prove to be a useful tool for automatic monitoring of insect pests in stored grain.

AN - 67644073; 19736788 AB - Psocids are an emerging problem in grain storage, handling, and processing facilities in the United States. We used data from two steel bins each containing 32.6 metric tonnes of wheat, Triticum aestivum L., to develop sampling plans for Liposcelis entomophila (Enderlein), Liposcelis decolor (Pearman) (both Psocoptera: Liposcelididae), and a mixture of the two species. Taylor's coefficients a (a sampling factor) and b (an index of aggregation) for these pests were calculated and incorporated into sampling protocols to improve accuracy. The optimal binomial sample sizes for estimating populations of these psocids at densities of < 25 psocids per refuge were large; therefore, we recommend the use of numerical sampling within this range of densities. Numerical sampling of L. entomophila and L. decolor at densities of < 25 psocids per refuge should not be too laborious given the low psocid numbers involved; we recommend using 10 refuges per bin. For presence-absence sampling of L. entomophila or L. decolor, 20 refuges per bin should be used at densities of 25-100 psocids per refuge. The sampling plans we have developed based on the use of cardboard refuges are convenient for use in steel bins containing wheat because they are inexpensive, provide a rapid assessment of psocid population incidence, and are easy to implement. These sampling plans can be used to monitor populations of and the efficacy of management strategies used against L. entomophila and L. decolor.

AN - 67642036; 19736774 AB - Susceptibility to the Cry1Ac toxin from Bacillus thuringiensis in tobacco budworm, Heliothis virescens (F.) (Lepidoptera: Noctuidae), is usually measured by performing bioassays under laboratory conditions. Accurate comparison of Cry1Ac susceptibility among H. virescens samples conducted in different places is challenged by several important methodological aspects, especially if different insect artificial diets are used to perform bioassays. In this study, we compared Cry1Ac susceptibility of four different-origin H. virescens colonies when challenged with this toxin incorporated into four different insect artificial diets. Our data show that Cry1Ac susceptibility was lower in all the H. virescens colonies for one of the commercial diets (Bio-Serv). Bio-Serv diet was one of the least significantly consumed diets by larvae of the four different colonies, which indicates that insects encountered less Cry1Ac toxin due to lower consumption of diet. Larvae fed Bio-Serv diet also seemed to display slower Cry1Ac toxin activation compared with larvae fed any of the other three diets tested. In contrast, a wheat germ-soybean diet (ARS) was one of the most consumed diets by the four H. virescens colonies. The increased consumption of ARS diet probably led to the high level of Cry1Ac susceptibility observed in all the H. virescens colonies. Our data highlight the importance of using common diets and use a standard tobacco budworm colony when comparing Cry1Ac susceptibility between diverse H. virescens strains or across time.

AN - 67641991; 19736749 AB - In 2006, U.S. Department of Agriculture-Animal and Plant Health Inspection Service published a landmark rule providing generic radiation quarantine treatments. The rule approved radiation doses of 150 Gy for any tephritid fruit fly and 400 Gy for all other insects except the pupa and adult stages of Lepidoptera. The generic radiation treatments apply to all fresh horticultural commodities. Therefore, if a pest risk assessment demonstrates that no pupae or adult Lepidoptera are associated with a commodity, export approval can be forthcoming with no further research. Generic treatments are the culmination of decades of research but not an end point. Future research on quarantine and phytosanitary uses of radiation should focus on 1) development of specific doses for quarantine Lepidoptera not covered by the generic treatments, 2) reduction of dose levels for specific pests and commodities to shorten treatment time and minimize any deleterious effects of radiation treatment on commodity quality, 3) development of generic doses below 400 Gy for important groups of quarantine arthropods other than fruit flies, and 4) development of information on commodity tolerance and development of value-added irradiated fresh products that use generic radiation treatments. Generic treatments will facilitate safe trade between countries that have approved phytosanitary uses of radiation for fresh agricultural commodities.

AN - 67549730; 19320558 AB - Exenatide is a peptide incretin mimetic that has glucoregulatory actions associated with weight reduction. Previous reports demonstrated acute increases in blood pressure after systemic or intracerebroventricular administration of exenatide or glucagon like peptide 1 (GLP 1) in rats. However, there are limited studies testing the chronic effects of these peptides on arterial pressure and no reports showing the effects of these peptides to reverse hypertension in the context of the metabolic syndrome. Thus, we examined the response to peripheral exenatide using telemetry in conscious, unrestrained rats under normotensive conditions and in a model of hypertension/metabolic syndrome induced by corticosterone. Rats were implanted with either corticosterone or wax (control) pellets, followed 14 days later by the additional implantation of pumps to deliver exenatide (1 microg/kg per day) or vehicle for 7 days. The 21-day corticosterone treatment produced hypertriglyceridemia, visceral fat deposition, hyperglycemia, insulin resistance, and an elevation of mean arterial blood pressure (MAP) by 14 +/- 1 mmHg. Exenatide significantly reversed corticosterone-induced increases in blood pressure and this normalization occurred independently from change in body weight. Additionally, exenatide reduced MAP by 5 +/- 3 mmHg in normotensive control rats. These results are the first demonstration of a durable antihypertensive effect of exenatide in a glucocorticoid-induced model of the metabolic syndrome.

AN - 67460168; 19559510 AB - Analysis of soil redistribution and sediment sources in semiarid and arid watersheds provides information for implementing management practices to improve rangeland conditions and reduce sediment loads to streams. The purpose of this research was to develop sediment budgets and identify potential sediment sources using (137)Cs and other soil properties in a series of small semiarid subwatersheds on the USDA ARS Walnut Gulch Experimental Watershed near Tombstone, Arizona, USA. Soils were sampled in a grid pattern on two small subwatersheds and along transects associated with soils and geomorphology on six larger subwatersheds. Soil samples were analyzed for (137)Cs and selected physical and chemical properties (i.e., bulk density, rocks, particle size, soil organic carbon). Suspended sediment samples collected at measuring flume sites on the Walnut Gulch Experimental Watershed were also analyzed for these properties. Soil redistribution measured using (137)Cs inventories for a small shrub-dominated subwatershed and a small grass-dominated subwatershed found eroding areas in these subwatersheds were losing -5.6 and -3.2tha(-1)yr(-1), respectively; however, a sediment budget for each of these subwatersheds, including depositional areas, found net soil loss to be -4.3tha(-1)yr(-1) from the shrub-dominated subwatershed and -0.1tha(-1)yr(-1) from the grass-dominated subwatershed. Generally, the suspended sediment collected at the flumes of the six other subwatersheds was enriched in silt and clay. Using a mixing model to determine sediment source indicated that shrub-dominated subwatersheds were contributing most of the suspended sediment that was measured at the outlet flume of the Walnut Gulch Experimental Watershed. The two methodologies (sediment budgets and sediment source analyses) indicate that shrub-dominated systems provide more suspended sediment to the stream systems. The sediment budget studies also suggest that sediment yields measured at the outlet of a watershed may be a poor indicator of actual soil redistribution rates within these semiarid watersheds. Management of these semiarid rangelands must consider techniques that will protect grass-dominated areas from shrub invasion to improve rangeland conditions.

AN - 67415128; 19458989 AB - Increased focus is being placed on the ability of native vegetation to mitigate potential harmful effects of agricultural runoff, especially pyrethroid insecticides. Replicate 379 L Rubbermaid tubs (1.25 m [l] x 0.6 m [w] x 0.8 m [h]) were planted with individual species of cutgrass (Leersia oryzoides), cattails (Typha latifolia), bur-reed (Sparganium americanum), and powdery alligator-flag (Thalia dealbata), all common wetland macrophytes found in the Mississippi Delta, USA, agricultural region. Permethrin-enriched water (target concentration, 5 microg L(-1)) was pumped in at a 4-h hydraulic retention time at one end of the tub and discharged at the far end. Water samples were collected from discharge at 1-h intervals for 12 h and analyzed for permethrin concentrations. Permethrin removal rates were compared for the four different plant treatments and nonvegetated sediment-water controls. Results indicated that no particular single plant species was more effective at removing permethrin in water relative to unplanted controls. Overall mass reductions (from inflow to outflow) for cis-permethrin ranged from 67% +/- 6% in T. latifolia to 71% +/- 2% in L. oryzoides. The trans-permethrin overall mass reductions ranged from 76% +/- 4% in S. americanum to 82% +/- 2% in the unplanted control. Sediment and plant samples collected at the study conclusion indicated that 77%-95% of measured permethrin mass was associated with sediment for mesocosms planted with L. oryzoides, T. latifolia, and T. dealbata. Conversely, mesocosms planted with S. americanum had 83% of measured mass associated with the plant material. Specific plant-pesticide retention studies can lead to improved planning for best management practices and remediation techniques such as constructed wetlands and vegetated agricultural drainage ditches.

To analyze spatial and temporal variability of crack development in a Vertisol with gilgai, soil cracks were measured on a 100-m (super 2) area of Laewest clay (fine, smectitic, hyperthermic Typic Hapludert) with native tallgrass vegetation on 42 dates from 1989 to 1998. Our objectives were to (i) report the distribution of Vertisol cracking across gilgai microtopography; (ii) estimate crack depth as a function of crack width considering gilgai; (iii) investigate the relationship of surface cracking and soil moisture considering gilgai and hysteresis. All surface cracks were mapped on scaled diagrams with width categorized, and some crack depth measured. Gravimetric soil moisture corresponding to crack measurements was measured on 18 dates, and on an additional 32 dates without crack measurements. Drying, wetting, and uniform soil moisture conditions were classified from the difference in soil moisture from 10- to 25-cm depths. Microtopography was quantified using a digital elevation model. Results showed that crack area density was greatest on microhighs and microslopes, though microlows had the largest cracking potential. The linear correlation between crack depth and width was moderately strong (r (super 2) =0.5), and not affected significantly by gilgai and hysteresis. However, taking hysteresis into account improved the linear regression models of crack area density versus soil moisture (up to r (super 2) =0.69) on both microhighs and microlows. Antecedent soil moisture seemed to impact in situ crack area density. Further field studies are recommended.

Land management practices, therefore, are sought that will reduce erosion and PM10 emissions during the summer fallow phase of the rotation. Horizontal soil flux and PM10 concentrations above adjacent field plots ( > 2 ha), with plots subject to conventional or undercutter tillage during summer fallow, were measured using creep and saltation/suspension collectors and PM10 samplers installed at various heights above the soil surface. After wheat harvest in 2004 and 2005, the plots were either disked (conventional) or undercut with wide sweeps (undercutter) the following spring and then periodically rodweeded prior to sowing wheat in late summer. Soil erosion from the fallow plots was measured during six sampling periods over two years; erosion or PM10 loss was not observed during two periods due to the presence of a crust on the soil surface. For the remaining sampling periods, total surface soil loss from conventional and undercutter tillage ranged from 3 to 40 g m-2 and 1 to 27 g m-2 while PM10 loss from conventional and undercutter tillage ranged from 0DT2 to 5DT0 g m-2 and 0DT1 to 3DT3 g m-2, respectively. Undercutter tillage resulted in a 15% to 65% reduction in soil loss and 30% to 70% reduction in PM10 loss as compared with conventional tillage at our field sites. Therefore, based on our results at two sites over two years, undercutter tillage appears to be an effective management practice to reduce dust emissions from agricultural land subject to a winter wheat-summer fallow rotation within the Columbia Plateau.

WTD were vaccinated with either M. bovis BCG strain Pasteur or BCG strain Danish. Both vaccinees and unvaccinated controls were subsequently inoculated with virulent M. bovis via the intratonsillar route. Real-time PCR was used to assess T-cell mRNA expression in peripheral blood leukocytes (PBL) from animals following vaccination and infection. Recall T-cell responses were measured by assessing the relative expression of gamma interferon (IFN-), T-cell-specific T-box transcription factor (Tbet), interleukin 12p40 (IL-12p40), IL-12p35, IL-23p19, FoxP3, IL-17, and GATA3 in PBL stimulated in vitro with purified protein derivative (PPD) of M. bovis or a recombinant fusion protein, ESAT6-CFP10. Animals vaccinated with BCG Danish expressed more IFN- and Tbet than either BCG Pasteur-vaccinated animals or unvaccinated controls. BCG Pasteur-vaccinated animals expressed more GATA3 than either group. After infection, unvaccinated controls expressed more Tbet and IL-12p40 than vaccinated animals. BCG Pasteur-vaccinated animals expressed more GATA3 than either the unvaccinated controls or the BCG Danish-vaccinated animals after infection. Animals were divided into pathology groups to correlate gene expression with severity of pathology. Animals in the visible lesion group expressed more Tbet and IFN- than animals that were culture negative, while Tbet and IFN- expression in the culture-positive, no-visible-lesion group was intermediate. GATA3 expression inversely correlated with pathology. Overall, expression of immune response genes correlated more closely with pathology than vaccination treatment.

Geometric multivariate designs coupled with response surface modeling allowed us to identify optimal blends of a two-component pheromone for attraction and trap disruption of the leafminer moth, Phyllocnistis citrella, a major pest in citrus growing areas around the world. Field trials confirmed that the natural 3:1 blend of (Z,Z,E)-7,11,13-hexadecatrienal:(Z,Z)-7,1 1-hexadecadienal was most effective as an attractant for male moths. However, the response surface generated in mating orientation trials revealed that the triene component alone was more effective than the natural blend in disrupting trap catch. Each individual component was effective at disrupting orientation in field trials, but (Z,Z,E)-7,11,13-hexadecatrienal was approximately 13 times more effective, at the same concentration, compared with (Z,Z)-7,11-hexadecadienal alone. In addition, the application of geometric design and response surface modeling to field studies provided insight into a possible mechanism of mating disruption and supported sensory imbalance as the operating mechanism for this species.

The Lysimeter CO sub(2) Gradient (LYCOG) chambers were constructed to maintain a linear gradient of atmospheric CO sub(2) (~250 to 500kll super(-1)) on grassland vegetation established on intact soil monoliths from three soil series. The chambers maintained a linear daytime CO sub(2) gradient from 263kll super(-1) at the subambient end of the gradient to 502kll super(-1) at the superambient end, as well as a linear nighttime CO sub(2) gradient. Temperature variation within the chambers affected aboveground biomass and evapotranspiration, but the effects of temperature were small compared to the expected effects of CO sub(2). Aboveground biomass on Austin soils was 40% less than on Bastrop and Houston soils. Biomass differences between soils resulted from variation in biomass of Sorghastrum nutans, Bouteloua curtipendula, Schizachyrium scoparium (C sub(4) grasses), and Solidago canadensis (C sub(3) forb), suggesting the CO sub(2) sensitivity of these species may differ among soils. Evapotranspiration did not differ among the soils, but the CO sub(2) sensitivity of leaf-level photosynthesis and water use efficiency in S.canadensis was greater on Houston and Bastrop than on Austin soils, whereas the CO sub(2) sensitivity of soil CO sub(2) efflux was greater on Bastrop soils than on Austin or Houston soils. The effects of soil type on CO sub(2) sensitivity may be smaller for some processes that are tightly coupled to microclimate. LYCOG is useful for discerning the effects of soil type on the CO sub(2) sensitivity of ecosystem function in grasslands.

Adult Poecilus cupreus and Harpalus pensylvanicus (Coleoptera: Carabidae) were fed pupae, second or third instar D. v. virgifera or a palatable surrogate prey, i.e., Calliphora vicina or Sarcophaga bullata larvae (Diptera: Calliphoridae, Sarcophagidae, respectively) of equivalent size. The ethanol-soluble fraction of third instar D. v. virgifera hemolymph was extracted and suspended in a 0.24 M sucrose solution and offered to H. pensylvanicus (using a sucrose only control for comparison). The mean duration until first consumption was recorded for each predator, as was the amount of time spent eating, cleaning, resting, or walking for 2 min post-attack (or 5 min for the sugar assay). Maggots and D. virgifera larvae and pupae were attacked equally by both predators. But upon attack, D. v. virgifera larval hemolymph coagulated onto the mouthparts of the predators, which they began vigorously cleaning. Predators ate the sucrose solution for significantly longer than hemolymph + sucrose solution, indicating the presence of deterrent chemicals in the hemolymph. This research suggests that D. v. virgifera larvae are defended from predation by sticky and repellent hemolymph. We hypothesize that this defense partially explains the widespread success of D. v. virgifera as an invasive pest.

The objective of this 4-yr on-farm study was to examine and compare the spatiotemporal patterns and dispersal of the southern green stink bug, Nezara viridula L., and the brown stink bug, Euschistus servus (Say), in six of these peanut-cotton farmscapes. GS+ Version 9 was used to generate interpolated estimates of stink bug density by inverse distance weighting. Interpolated stink bug population raster maps were constructed using ArcMap Version 9.2. This technique was used to show any change in distribution of stink bugs in the farmscape over time. SADIE (spatial analysis by distance indices) methodology was used to examine spatial aggregation of individual stink bug species and spatial association of the two stink bug species in the individual crops. Altogether, the spatiotemporal analyses for the farmscapes showed that some N. viridula and E. servus nymphs and adults that develop in peanuts disperse into cotton. When these stink bugs disperse from peanuts into cotton, they aggregate in cotton at the interface, or common boundary, of the two crops while feeding on cotton bolls. Therefore, there is a pronounced edge effect observed in the distribution of stink bugs as they colonize the new crop, cotton. The driving force for the spatiotemporal distribution and dispersal of both stink bug species in peanut-cotton farmscapes seems to be availability of food in time and space mitigated by landscape structure. Thus, an understanding of farmscape ecology of stink bugs and their natural enemies is necessary to strategically place, in time and space, biologically based management strategies that control stink bug populations while conserving natural enemies and the environment and reducing off-farm inputs.

Approaches to engineer pentose-fermenting yeasts have required expression of additional genes. We implemented a high- throughput strategy to improve anaerobic growth on xylose and rate of ethanol production by evaluating overexpression of each native S. cerevisiae gene from a collection of haploid PJ69-4 MATa strains expressing the gene open reading frames (ORFs) mated to a haploid PJ69-4 MATalpha strain expressing the Piromyces sp.E2 xylose isomerase (XI) gene. The resulting 6113 diploid strains containing the XI gene and a different yeast gene ORF were screened for growth on xylose in anaerobic plate cultures using an integrated robotic workcell. Nine unique strains were isolated; two were found to no longer grow on glucose; seven were further evaluated for fermentation of alkaline peroxide pretreated enzymatically saccharified wheat straw hydrolysate. All successfully used glucose and xylose, consuming most of the glucose and a small amount of the xylose. Transforming the strains with an additional vector expressing xylulokinase gene did not improve anaerobic growth on xylose but improved glucose use and ethanol production on the hydrolysate, with three strains giving maximum ethanol production >=14.0 g L super(-1).

Both chemicals generally have been regarded as protein cues that result in female-biased attraction. Using electroantennography (EAG) and flight tunnel bioassays, this study evaluated response of the Caribbean fruit fly, Anastrepha suspensa (Loew) to vapors released from commercial lure formulations of ammonium bicarbonate and putrescine. Over a range of doses tested, EAG response to ammonium bicarbonate was equivalent for both sexes, but female response was significantly greater than male response to putrescine and to a 1:1 mixture of ammonium bicarbonate and putrescine. Amplitude of EAG response to the mixture was approximately equal to the summation of responses to the individual substrates. Using a fixed dose of substrate, EAG measurements from females 1-14 d old indicated that antennal sensitivity to both lures varied according to physiological state of the fly. Peak response to ammonium bicarbonate was recorded from immature females, peak response to putrescine from sexually mature females. In bioassays, more females were captured with ammonium bicarbonate plus putrescine than with ammonium bicarbonate alone. This difference was not observed in males, resulting in a higher female to male ratio in captures with ammonium bicarbonate plus putreseine (3:1) versus ammonium bicarbonate alone (1:1). Results suggest that separate olfactory receptors are involved in detection of the two semiochemicals, and that the putrescine component is primarily responsible for the female-biased attraction.

GF-120 is an organically registered attractive bait for tephritid fruit flies composed of spinosad, hydrolyzed protein (Solulys), high-fructose corn syrup (ADM CornSweet 42 high-fructose corn syrup, referred to as invertose sugar or invertose here), vegetable oils, adjuvants, humectants, and attractants. Tests were carried out with non-Africanized honey bees in February and March 2005 and 2007 during periods of maximum hunger for these bees. In all tests, bees were first trained to forage from plates of 30% honey-water (2005) or 30% invertose (2007). In 2005 bees were offered choices between honey-water and various bait components, including the complete toxic bait. In 2007, similar tests were performed except bees were attracted with 30% invertose then offered the bait components or complete bait as no-choice tests. Initially, the 2005 tests used all the components of GF-120 except the spinosad as the test bait. After we were convinced that bees would not collect or be contaminated by the bait, we tested the complete GF-120. Behavior of the bees indicated that during initial attraction and after switching the baits, the bait components and the complete bait were repellent to honey bees, but the honey-water remained attractive. Invertose was shown to be less attractive to bees, addition of Solulys eliminated almost all bee activity, and addition of ammonium acetate completely eliminated feeding in both choice and no-choice tests. These results confirm previous tests showing that bees do not feed on GF-120 and also show that honey bees are repelled by the fruit fly attractant components of the bait in field tests.

Swine waste samples were taken at different depths with a pulley system equipped with a special sampler that allows for sampling exclusively at certain depth. Chemicals and microbial dynamics were monitored throughout a one-year-period. Results showed that nutrient (C, N, P, S) concentrations varied according to stratified lagoon layers and season. Trace minerals (Al, Ca, Fe, and Mg), on the other hand, appeared to be affected more by stratification than seasonal variability. Molecular analysis also showed that microbial community structure appeared to be affected by the stratification and seasonal variability. Based on these data, it is important to consider the effect of stratification and seasonal variability in managing these open lagoons.

It is spread by citrus psyllids and is associated with a low-titer, phloem-limited infection by any of three uncultured species of a-Proteobacteria, 'Candidatus Liberibacter asiaticus', 'Ca. L. americanus', and 'Ca. L. africanus'. A complete circular 'Ca. L. asiaticus' genome has been obtained by metagenomics, using the DNA extracted from a single 'Ca. L. asiaticus'-infected psyllid. The 1.23-Mb genome has an average 36.5% GC content Annotation revealed a high percentage of genes Involved in both cell mo-tility (4.5%) and active transport in genera] (8.0%), which may contribute to its virulence. 'Ca. L. asiaticus' appears to have a limited ability for aerobic respiration and is likely auxotrophic for at least five amino acids. Consistent with its intracellular nature, 'Ca. L. asiaticus' lacks type III and type IV secretion systems as well as typical free-living or plant-colonizing extracellular degradative enzymes. 'Ca. L. asiaticus' appears to have all type I secretion system genes needed for both multidrug efflux and toxin effector secretion. Multi-protein phylogenetic analysis confirmed 'Ca. L. asiaticus' as an early-branching and highly divergent member of the family Rhizobiaceae. This is the first genome sequence of an uncultured a-proteobacteria that is both an intracellular plant pathogen and insect symbiont.

Recombinant d-giardin antigen was expressed in Escherichia coli as a poly-histidine fusion protein and was purified by affinity chromatography for production of antisera to d-giardin. By immunoblotting analysis, antisera to recombinant d-giardin antigen recognized a 31-kDa protein on G. lamblia trophozoites. Anti-recombinant d-giardin was used to localize the native protein to the trophozoite ventral disk in both immunofluorescence and immunoelectron microscopy assays. Pre-treatment of G. lamblia trophozoites with anti-d-giardin sera caused morphological changes in the parasite and inhibited trophozoite binding to the surface of cell culture slides. Binding of antibodies to d-giardin may provide a means of inhibiting attachment of G. lamblia trophozoites to the intestinal epithelium and thereby prevent clinical giardiasis.

(Hemiptera: Pentatomidae) is a serious pest of macadamia nuts, Macadamia integrifolia, in Hawaii. Using ruthenium red dye to stain stink bug feeding probes, feeding activity was determined for nuts of various maturity levels harvested from the tree and off the ground throughout the growing season in five commercial cultivars. Damage occurred in the tree and on the ground during all nut growth stages. Damage on the ground was often higher than in the tree. Cultivar 246 was more susceptible to attack than cultivars 333 and 800. It was previously thought that cultivar susceptibility was related to husk and shell thickness, but cultivar 246 showed higher damage than other cultivars even during early nut development when the nuts are small and before the shell has formed. This suggests that shell and husk thickness may play a secondary role in susceptibility to feeding by N. viridula. Monitoring N. viridula feeding activity during early nut development may help alert growers to potential problems later in the season, but early-season probing activity in immature nuts was not a good predictor of damage levels in mature nuts later in the season in our study.

In this experiment, we compared the abundance, species richness, diversity, and composition of arthropods in 9.3-ha plots in which either (1) all coarse woody debris was removed, (2) a large number of logs were added, (3) a large number of snags were added, or (4) no coarse woody debris was added or removed. The target taxa were ground-dwelling arthropods, sampled by pitfall traps, and saproxylic beetles (i.e., dependent on dead wood), sampled by flight intercept traps and emergence traps. There were no differences in total ground-dwelling arthropod abundance, richness, diversity, or composition among treatments. Only the results for ground beetles (Carabidae), which were more species rich and diverse in log input plots, supported our prediction that ground-dwelling arthropods would benefit from additions of dead wood. There were also no differences in saproxylic beetle abundance, richness, diversity, or composition among treatments. The findings from this study are encouraging in that arthropods seem less sensitive than expected to manipulations of dead wood in managed pine forests of the southeastern United States. Based on our results, we cannot recommend inputting large amounts of dead wood for conservation purposes, given the expense of such measures. However, the persistence of saproxylic beetles requires that an adequate amount of dead wood is available in the landscape, and we recommend that dead wood be retained whenever possible in managed pine forests.

Both forms of recombinant cellulases showed hydrolytic activity on cellulosic substrates. The nCfEG was more active and stable than tCfEG even though the latter could be purified to near homogeneity with a simple procedure. The differential activities of nCfEG and tCfEG were also evidenced by hydrolytic products they produced on different substrates. On CMC, both acted as an endoglucanase, randomly hydrolyzing internal b-1,4-glycosidic bonds and resulting in a smear of polymers with different lengths, although cellobiose, cellotriose, and cellotetraose equivalents were noticeable. The hydrolytic products of tCfEG were one unit sugar less than those produced by nCfEG. Using filter paper as substrate, however, the major hydrolytic products of nCfEG were cellobiose, cellotriose and trace of glucose; those of tCfEG were cellobiose, cellotriose and trace of cellotetraose, indicating a property similar to that of cellobiohydrolase, an exoglucanase. The results presented in this report uncovered the biochemical properties of the recombinant cellulase derived from the intact gene of Formosan subterranean termites. The recombinant cellulase would be useful in designing cellulase-inhibiting termiticides and incorporating into a sugar-based biofuel production program.

Gene isolation was first attempted by degenerate PCR on an A. suspensa adult male testes cDNA library, which fortuitously isolated the 2.85 kb b1-tubulin gene that encodes a 447 amino acid polypeptide. Subsequent PCR using 5' and 3' RACE generated the 1.4 kb Asb2-tubulin gene that encodes a 446 amino acid polypeptide. Using primers to conserved sequences, the highly similar A. ludens and B. dorsalis b2-tubulin genes, encoding identical amino acid sequences, were then isolated. To verify Asb2-tubulin gene identification based on gene expression, qRT-PCR showed that Asb2-tubulin transcript was most abundant in pupal and adult males, and specific to the testes. This was further tested in transformants having the DsRed.T3 reporter gene regulated by the Asb2-tubulin 1.3 kb promoter region. Fluorescent protein was specifically expressed in testes from third instar larvae to adults, and fluorescent sperm could be detected in the spermathecae of non-transgenic females mated to transgenic males.To confirm these matings, a PCR protocol was developed specific to the transgenic sperm DNA.

More than 50 moths from each sample location and time were genotyped at eight microsatellite loci. Spatial analyses indicated that there is no spatial genetic structuring between European corn borer populations sampled 720 km apart at the extremes of the transects and no pattern of genetic isolation by distance at that geographic scale. Although these results suggest high gene flow over the spatial scale tested, it is possible that populations have not had time to diverge since the central Corn Belt was invaded by this insect -60 yr ago. However, temporal analyses of genetic changes in single locations over time suggest that the rate of migration is indeed very high. The results of this study suggest that the geographic dimensions of European corn borer populations are quite large, indicating that monitoring for resistance to transgenic Bt corn at widely separated distances is justified, at least in the central Corn Belt. High gene flow further implies that resistance to Bt corn may be slow to evolve, but once it does develop, it may spread geographically with such speed that mitigation strategies will have to be implemented quickly to be effective.

Blake is widely distributed throughout peninsular Florida and poses a significant threat to species diversity in the wetland systems of the Everglades. Mitigation of this threat includes the areawide release campaign of the biological control agents Oxyops vitiosa Pascoe and Boreioglycaspis melaleucae Moore. We summarize the results of this release effort and quantify the resulting geographic distribution of the herbivores as well as their regional impact on the target weed. A combined total of 3.3 million individual Melaleuca biological control agents have been redistributed to 407 locations and among 15 Florida counties. Surveys of the invaded a the geogO. vitiosa encompasses 71% of the Melaleuca infestation. Although released 5 yr later, the distribution of B. melaleuca is slightly greater than its predecessor, with a range including 78% of the sampled Melaleuca stands. Melaleuca stands outside both biological control agents' distributions occurred primarily in the northern extremes of the tree's range. Strong positive association between herbivore species was observed, with the same density of both species occurring in 162 stands and no evidence of interspecific competition. Soil type also influenced the incidence of biological control agents and the distribution of their impacts. The odds of encountering O. vitiosa or B. melaleucae in cells dominated by sandy soils were 2.2 and 2.9 times more likely than those predominated by organically rich soils. As a result, a greater level of damage from both herbivores was observed for stands growing on sandy versus organic-rich soils.

The experiment was conducted on the 786 km(2) Ft. Cobb Reservoir experimental watershed (FCREW) in southwestern Oklahoma. Precipitation data sets included the National Weather Service (NWS) cooperative weather network (Co-op), NWS next-generation radar precipitation estimates (NEXRAD), the University of Oklahoma and Oklahoma State University's joint state-wide weather station network (Mesonet), and the USDA-ARS weather station network (Micronet) deployed in the FCREW. The FCREW was divided into three main subwatersheds (Cobb, Lake, and Willow Creeks), with SWAT calibrated for each subwatershed using each precipitation data set. Model simulations were generally 'good'to 'very good' at both the daily and monthly time steps for all precipitation data sets, except in the Willow Creek subwatershed, which scored 'satisfactory' at the monthly time step and 'unsatisfactory' at the daily time step when the Co-op data were used. Calibrated parameter values within the Cobb Creek subwatershed changed little across precipitation data sets. In the Lake Creek and Willow Creek subwatersheds, the deep recharge calibration parameter values varied greatly with respect to precipitation data source. Such variation could inappropriately affect, for example, model assessments of conservation practices designed to ameliorate the movement of agro-chemicals from the surface to lower positions in the soil profile and eventually into the groundwater.

Response of the hydrology components to different grid sizes was analyzed by considering: (1) changes in input parameter values due to GIS manipulation processes, and (2) comprehensive response of the model through applications to a small agricultural subwatershed (QN2) in the Nomini Creek watershed, Virginia. In addition, model response to different time steps was analyzed in QN2 by changing the storm event time step (SET) of the model (1, 5,10,15, 30, 45, and 60 min) against a fixed grid size. A maximum acceptable grid size (MAG) of 90 m was selected for QN2, considering changes in the accuracy of spatial data for different grid sizes. Only the overall response of the hydrology components to down-scaled (60 m) grid size in QN2 was acceptable without any further calibration. Daily streamflow for storm events decreased with increases in time step from 1 to 60 min, while total runoff for the simulation period increased slightly by 8%. Use of MAG (90 m) with an acceptable larger time step (10 min) based on monthly runoff criteria exponentially reduced computational time compared to an application using the smallest grid size and time step. Site-specific sensitivity analysis is recommended due to the possible differences in response of the hydrology components to watersheds with different hydrologic characteristics.

The primary sources of N(2)O from dairy farms are nitrification and denitrification processes in soil, with smaller contributions from manure storage and barn floors. Emissions from all greenhouse gas sources are interrelated, so strategies to reduce emissions from one source can affect emissions from another. Therefore, a comprehensive whole-farm evaluation is needed, which can be cost-effectively achieved through computer simulation. The Integrated Farm System Model (IFSM), a process-based whole-farm model, was extended to simulate sources off N(2)O and other greenhouse gas emissions. A module was added to simulate N(2)O emissions from croplands using relationships from the previously established DAYCENT model, and relationships were incorporated to predict emissions from slurry storage and free-stall barn floors. The new module was found to predict N(2)O emissions consistent with reported values from specific experiments and previously estimated whole-farm emissions. The model also predicted sensitivity to soil texture and soil water content similar to experimental data and DAYCENT model predictions, which further verified this most important component of N(2)O emissions. Simulations illustrated the impact of management practices on a representative farm in central Pennsylvania. Reducing the use of inorganic fertilizer by accounting for manure nitrogen (N) reduced N(2)O emission from the farm by 6% and reduced the net farm emission of all greenhouse gases in CO(2)-equivalent units by 1%. Adding a mulch cover crop to corn land reduced N(2)O emission by 34% with a 7% reduction of all greenhouse gases. Use of a top-loaded manure storage tank prevented formation of a surface crust, which eliminated storage N(2)O emission with little effect on net farm emission of all greenhouse gases. This extended whole-farm model provides a tool for evaluating proposed N(2)O reduction strategies along with their effects on other greenhouse gas emissions, other N and phosphorus losses, and farm profitability.

The study randomized 42 middle schools to intervention or control, and followed students from the sixth to the eighth grades. Participants were a racially, ethnically and geographically diverse cohort from across the United States. Here, we describe the conceptual underpinnings and design of the social marketing-based communications component of the HEALTHY study intervention that combined changes in the school nutrition and physical education (PE) environment with behavior change initiatives. The communications intervention component coordinated multiple elements to deliver campaigns that served to integrate and support all aspects of the HEALTHY intervention. The campaigns unfolded across five semesters of middle school, each targeting a specific theme related to the HEALTHY objectives. Communications campaigns comprised (1) core elements such as branding, posters, banners and visual and verbal messaging, (2) student events supporting the nutrition, PE and behavior intervention components through the application of social marketing and communications strategies, including the incorporation of student-generated media and (3) distribution of premiums and theme enhancers to extend the visibility of the study beyond the intervention environment. Formative research conducted with students, parents and school administrators was used to refine the communications strategy. Student peer communicators selected from the student body were involved to influence the normative student environment. Marketing and creative design experts developed a brand, logo, activities and materials. In the latter half of the study, student-generated messages and media were used to reflect local interests and culture and enhance peer influence. The HEALTHY intervention delivery and impact were strengthened by the communications strategies. The HEALTHY experience provides practical considerations for systematically incorporating a social marketing-based communications approach within future school-based health behavior interventions.International Journal of Obesity (2009) 33, S52-S59; doi:10.1038/ijo.2009.117 JF - International Journal of Obesity AU - DeBar, L L AU - Schneider, M AU - Ford, E G AU - Hernandez, A E AU - Showell, B AU - Drews, K L AU - Moe, E L AU - Gillis, B AU - Jessup, A N AU - Stadler, D D AU - White, M AD - USDA/ARS Children's Nutrition Research Center, Baylor College of Medicine, Houston, TX, USA Y1 - 2009/08// PY - 2009 DA - Aug 2009 SP - S52 EP - S59 PB - Nature Publishing Group, The Macmillan Building London N1 9XW UK VL - 33 IS - S4 SN - 0307-0565, 0307-0565 KW - Risk Abstracts KW - marketing KW - obesity KW - Nutrition KW - logos KW - risk reduction KW - diabetes mellitus KW - Education KW - USA KW - Communications KW - schools KW - intervention KW - Visibility KW - R2 23060:Medical and environmental health UR - http://libproxy.lib.unc.edu/login?url=http://search.proquest.com/docview/20945114?accountid=14244 L2 - http://vb3lk7eb4t.search.serialssolutions.com/?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQ%3Ariskabstracts&rft_val_fmt=info:ofi/fmt:kev:mtx:journal&rft.genre=article&rft.jtitle=International+Journal+of+Obesity&rft.atitle=Social+marketing-based+communications+to+integrate+and+support+the+HEALTHY+study+intervention&rft.au=DeBar%2C+L+L%3BSchneider%2C+M%3BFord%2C+E+G%3BHernandez%2C+A+E%3BShowell%2C+B%3BDrews%2C+K+L%3BMoe%2C+E+L%3BGillis%2C+B%3BJessup%2C+A+N%3BStadler%2C+D+D%3BWhite%2C+M&rft.aulast=DeBar&rft.aufirst=L&rft.date=2009-08-01&rft.volume=33&rft.issue=S4&rft.spage=S52&rft.isbn=&rft.btitle=&rft.title=International+Journal+of+Obesity&rft.issn=03070565&rft_id=info:doi/10.1038%2Fijo.2009.117 LA - English DB - ProQuest Environmental Science Collection N1 - Date revised - 2009-10-01 N1 - Last updated - 2011-12-14 N1 - SubjectsTermNotLitGenreText - USA; intervention; Communications; schools; marketing; Nutrition; obesity; Education; logos; diabetes mellitus; risk reduction; Visibility DO - http://dx.doi.org/10.1038/ijo.2009.117 ER - TY - JOUR T1 - Simulation of carbon dioxide emissions from dairy farms to assess greenhouse gas reduction strategies AN - 20942783; 11051528 AB - Farming practices can have a large impact on the soil carbon cycle and the resulting net emission of greenhouse gases including carbon dioxide (CO(2)), methane, and nitrous oxide. Primary sources of CO(2)emission on dairy farms are soil, plant, and animal respiration, with smaller contributions from microbial respiration in manure. Strategies designed to reduce emissions from one source can cause an increase in emissions from another source. Therefore, a comprehensive whole-farm evaluation is needed, which can be cost-effectively met through computer simulation. The Integrated Farm System Model (IFSM), a process-based whole-farm model, was extended to simulate the carbon cycle. Relationships were added to represent photosynthetic fixation, soil and plant respiration, animal respiration, and emissions from manure storage and barn floors. The new module was verified to predict the mass of carbon present in soil pools at the end of annual simulations and to predict CO(2) emissions within expected emission ranges for both specific sources and overall farm emissions. A farm-level carbon balance was used to further verify that predicted emissions were reasonable across a variety of production strategies. Farm simulations illustrated that changes in cropping practices affected emissions from all farm sources, with a primary effect on the assimilation of CO(2)in feed production. For a representative farm in central Pennsylvania, use of more alfalfa in place of corn production caused a 6% increase in net farm greenhouse gas emission in CO(2)-equivalent units, while replacing non-permanent grassland with corn production reduced the net emission by 16%. Changing from a Holstein herd to Jersey animals with animal numbers increased to produce the same amount of milk affected most emission sources, with a net impact of increasing the net greenhouse gas emission by 20%. Incorporation of greenhouse gas emission modules in IFSM provides a more comprehensive tool for evaluating the overall farm-level environmental and economic impacts of management scenarios used to reduce emissions.

Three strains of M. anisopliae - F52, TM109, and MA1200 - formed MS in shake flask cultures using media with varying carbon concentrations and carbon-to-nitrogen (C:N) ratios. Under the conditions of this study, all strains produced MS, compact hyphal aggregates that become pigmented with culture age, in addition to more typical blastospores and mycelia. While all strains formed desiccation tolerant MS, highest concentrations (2.7-2.9 x 10 super(8) L super(-1) liquid medium) were produced in rich media with C:N ratios of 30:1 and 50:1 by strain F52. All three strains of M. anisopliae produced similar biomass concentrations when media and growth time were compared. Strain MA1200 produced higher concentrations of blastospores than the other two strains of M. anisopliae with highest blastospore concentrations (1.6 and 4.2 x 10 super(8) blastospores ml super(-1) on days 4 and 8, respectively) in media with the highest carbon and nitrogen concentrations. Microsclerotial preparations of M. anisopliae containing diatomaceous earth survived air-drying (to <5 % moisture) with no significant loss in viability. Rehydration and incubation of air-dried MS granules on water agar plates resulted in hyphal germination and sporogenic germination to produce high concentrations of conidia. Bioassays using soil-incorporated, air- dried MS preparations resulted in significant infection and mortality in larvae of the sugar beet root maggot, Tetanops myopaeformis.

Understanding the emergence and spread of this pathogen is important for controlling the disease. To build a fingerprinting database for reliable identification and tracking of strains of A. avenae subsp. citrulli, a multilocus sequence typing (MLST) scheme was developed using seven conserved loci. The study included 8 original strains from the 1978 description of A. avenae subsp. citrulli, 51 from China, and 34 from worldwide collections. Two major clonal complexes (CCs), CC1 and CC2, were identified within A. avenae subsp. citrulli; 48 strains typed as CC1 and 45 as CC2. All eight original 1978 strains isolated from watermelon and melon grouped in CC1. CC2 strains were predominant in the worldwide collection and all but five were isolated from watermelon. In China, a major seed producer for melon and watermelon, the predominant strains were CC1 and were found nearly equally on melon and watermelon.

Anamorphic characters were in close agreement with descriptions of Erysiphe trifolii. However, teleomorphs formed chasmothecial appendages with highly branched apices, whereas E. trifolii has been described as producing flexuous or sometimes loosely branched appendages. Branched appendages have been described in Erysiphe diffusa, a fungus reported from species of Lens, Glycine, and Sophora, raising the possibility that the PNW fungus could be E. diffusa. Examination of morphological characters of an authentic specimen of E. trifolii from Austria determined that it included chasmothecial appendages resembling those seen in PNW specimens. Furthermore, ITS sequences from five powdery mildew samples collected from lentils in PNW greenhouses and fields from 2006 to 2008 were identical to one another, and exhibited higher similarity to sequences of E. trifolii (99%) than to those of any other Erysiphe spp. available in GenBank. Parsimony analysis grouped the lentil powdery mildew into a clade with Erysiphe baeumleri, E. trifolii, and E. trifolii-like Oidium sp., but indicated a more distant relationship to E. diffusa. In greenhouse inoculation studies, the lentil powdery mildew fungus did not infect soybean genotypes known to be susceptible to E. diffusa. The pathogenicity of E. trifolii on lentil was confirmed using modified Koch's postulates. This is the first report of E. trifolii infecting lentil. E. diffusa and E. trifolii have different host ranges, so the discovery of E. trifolii on lentil has implications both for determining species of powdery mildews on cool-season grain legumes, and in disease management.

The Negative Binomial density distribution can handle any N that is large with respect to the test size, but is limited to the precision of two parameter functions. Its application is simple and rapid, particularly at large l, and useful for obtaining the lot average concentration, . The non-parametric method can handle any approximation to the experimental data. It is treated as a sum of Poisson (or multinomial) distributions with varying l sub(l)=Np sub(l), where p sub(l) is the probability of a kernel containing contaminant in a range of c. This method is currently restricted to l sub(l)<2, and is more laborious than the Negative Binomial. It is ideal for discerning small changes in P(C; N) at small N, indicative of the effects of production, processing and sorting. These methods were applied to the analysis of contamination in assorted processed and unprocessed pistachios, almonds, and peanuts. For this paper, the method is illustrated using aflatoxin contamination of various commodities, but the method can be applied to any contaminant of a granular commodity. The sparse approximation for distributions (l sub(l)<0.1), previously postulated, was verified. P(C; N) at low C was established in all cases, leading to a much clearer understanding of the source of contamination. The overall shapes of P(C; N) at low N were alike among tree nuts and among two very different peanut lots. Where available, test data at widely spaced N were consistent with calculated results. In one pistachio lot, the change of P(C; N) upon image sorting indicated a hitherto unknown contamination source. The methods show great applicability for risk analysis and developing sampling protocols.

We quantified differences in infiltration, runoff, soil loss, and interrill erodibilities (K sub(i)) for three soils: Compass loamy sand, Decatur silt loam, and Tifton loamy sand managed under conventional- (CT), strip- (ST), and/or no-till (NT) systems with and without a residue cover (rye [Secale cerale L.]) (+C/-C) and with and without paratilling (+P/-P). Duplicate plots (1 m super(2) [ similar to 10 ft super(2)]) on each tillage treatment received simulated rainfall (50 mm h super(-1) [2 in hr super(-1)] for two hours). Runoff and sediment yields were continuously measured, and K sub(i) values were calculated from measured data. The Water Erosion Prediction Project (WEPP) model was used to extend experimental data to long-term annual trends. For the Compass soil, NT--C plots increased runoff by as much as 43% and sediment yields by as much as 10-fold compared to NT+C plots. The NT+P+C plots decreased runoff by as much as 70% and sediment yields by 24-fold compared to CT-P-C. For the Decatur soil, NT+P plots decreased runoff by as much as 71% and sediment yields by as much as 2.7-fold compared to NT-P plots.The NT+P+C plots decreased runoff by as much as 73% and sediment yields by as much as 11.8-fold compared, to CT-P-C. For the Tifton soil, ST+P+C plots decreased runoff by as much as 44% and sediment yields by as much as 2.7-fold compared to CT-P-C plots. Calculated K sub(i) values for the Compass, Decatur, and Tifton soils were 0.37, 0.40, and 0.24, respectively. Residue cover decreased effective interrill erodibilities (K sub(ieff)) values by 11%, 2-fold, and 2.6-fold for the Decatur, Tifton, and Compass soils, respectively; Paratilling decreased K sub(ieff) values by 3-fold for the Compass and Decatur soils. The NT and/or ST systems had lower K sub(ieff) values than K sub(i). values from corresponding GT-P-C treatments (Compass = 4- to 37-fold; Decatur = 4- to 13-fold; Tifton = 2-fold). Converting from a CT to a NT or ST system reduced predicted runoff (Compass = 1.7-fold; Decatur = 10% to 17%; Tifton = 1.6- to 2.3-fold) and sediment yields (Compass = 10- to 12-fold; Decatur = 6- to 33-fold; Tifton = 7.3- to 12.1-fold). The most benefit of NT or ST, as quantified by the maximum difference in 100-year predicted runoff and sediment yields, was for the Compass (78%) and Tifton (75%) soils for runoff and for the Compass (10.3-fold) and Decatur soils (9.7-fold) for sediment. Conservation tillage systems (NT, ST) coupled with surface residue cover and/or paratilling are effective in reducing runoff and sediment yields from highly-weathered soils by lowering effective K sub(i) values.

A three-year controlled study was recently completed to compare polyacrylamide soil treatment to the traditional cover method using agricultural straw on high severity burned soils of the Red Bull Fire, which burned through the Uinta National Forest near Provo, Utah, in July and August of 2004. Weed free, recycled paper pellets containing polyacrylamide were found to be an effective Burn Area Emergency Rehabilitation treatment option on clay rich soils containing divalent cations (i.e., Ca super(2+)) within the soil matrix. This study showed aerial application of the granular polyacrylamide pellets resulted in an even distribution of the polymer-based product on the soil surface. Through water activation, a blend of water-soluble linear anionic polyacrylamide copolymers are slowly released, which bind with the soil particles, structurally stabilizing the soil. When compared to agricultural straw, polyacrylamide results show improved revegetation, reduced soil hydrophobicity, and reduced soil erosion.

Impact assessments documenting how habitat and aquatic biota within streams respond to these practices are needed for evaluating the effects of conservation practices. Numerous sampling protocols have been developed for monitoring streams. However, protocols designed for monitoring studies are not appropriate for impact assessments. We developed guiding principles for designing impact assessments of ecological responses to conservation practices. The guiding principles are as follows: (1) develop the hypothesis first, (2) use replicated experimental designs having controls and treatments, (3) assess the habitat and biological characteristics with quantitative and repeatable sampling methods, (4) use multiple sampling techniques for collecting aquatic organisms, and (5) standardize sampling efforts for aquatic organisms. The guiding principles were applied in designing a study intended to evaluate the influence of herbaceous riparian buffers on channelized headwater streams in central Ohio. Our example highlights that the application of our recommendations will result in impact assessments that are hypothesis-driven and incorporate quantitative methods for the measurement of abiotic and biotic attributes.

The gene structure was determined and compared to that of several pyranose 2-oxidases cloned from white-rot fungi. The G. trabeum pyranose 2-oxidase gene consists of 16 coding exons with canonical promoter CAAT and TATA elements in the 5'UTR. The corresponding G. trabeum cDNA was cloned and contains an ORF of 1,962 base pairs encoding a 653 amino acid polypeptide with a predicted molecular weight of 72 kDa. A Hisx6 tagged recombinant G. trabeum pyranose 2-oxidase was generated and expressed heterologously in Escherichia coli yielding 15 U enzyme activity per ml of induced culture. Structural alignment and phylogenetic analysis were performed and are discussed.

Beta-lactams showed broad activity against all genera, although leuconostocs and lactobacilli were highly resistant to oxacillin (80% to 95.5%). Resistance to aminoglycosides was frequent for lactococci and enterococci (particularly for streptomycin), whereas lower rates of resistance were detected for lactobacilli and leuconostocs. Technologically interesting traits for the food industry were distributed among isolates that showed different degrees of resistance to common antibiotics. However, isolates showing resistance to less than 2 antibiotics were mainly those with properties of greatest technological interest (acidifying activity, proteolytic-lipolytic activities, or diacetyl production).

A compatible Tsnl-ToxA interaction is known to play a major role in conferring susceptibility of hexaploid (common) wheat to SNB. However, a recent study by another group suggested that the Tsn1-ToxA interaction was not relevant in conferring susceptibility of the tetraploid (durum) wheat cv. Langdon (LDN). Here, we reevaluated the role of the Tsn1-ToxA interaction in governing SNB susceptibility using the same mapping population and Stagonospora nodorum isolate (Sn2000) as were used in the previous study. Results of our quantitative trait locus analysis showed that the Tsn1 locus accounted for 95% of the variation in SNB. In addition, inoculation of the mapping population with two ToxA-knockout strains of Sn2000 revealed that the entire population was resistant. Furthermore, several LDN Tsn1 -disrupted mutants were evaluated and found to be resistant to SNB. Together, these results prove unequivocally that Tsn1 is the only factor present along chromosome 5B that governs response to SNB in this population and that a compatible Tsn1-ToxA interaction is necessary for the manifestation of disease. Therefore, the results from the previous study are refuted.

However, the cost of carnivory includes decreased AN and increased respiration rates (RD) of trapping organs. The principal aim of the present study was to assess the costs and benefits of carnivory in the pitcher plant Nepenthes talangensis, leaves of which are composed of a lamina and a pitcher trap, in response to feeding with beetle larvae.Methods Pitchers of Nepenthes grown at 200 kmol m-2 s-1 photosynthetically active radiation (PAR) were fed with insect larvae for 2 months, and the effects on the photosynthetic processes were then assessed by simultaneous measurements of gas exchange and chlorophyll fluorescence of laminae and pitchers, which were correlated with nitrogen, carbon and total chlorophyll concentrations.Key Results AN and maximum (Fv/Fm) and effective quantum yield of photosystem II (PSII) were greater in the fed than unfed laminae but not in the fed compared with unfed pitchers. Respiration rate was not significantly affected in fed compared with unfed plants. The unfed plants had greater non-photochemical quenching (NPQ) of chlorophyll fluorescence. Higher NPQ in unfed lamina did not compensate for their lower PSII, resulting in lower photochemical quenching (QP) and thus higher excitation pressure on PSII. Biomass and nitrogen and chlorophyll concentration also increased as a result of feeding. The cost of carnivory was shown by lower AN and PSII in pitchers than in laminae, but RD depended on whether it was expressed on a dry weight or a surface area basis. Correlation between nitrogen and AN in the pitchers was not found. Cost-benefit analysis showed a large beneficial effect on photosynthesis from feeding as light intensity increased from 200 to 1000 kmol m-2 s-1 PAR after which it did not increase further. All fed plants began to flower.Conclusion Feeding pitchers with insect larvae increases AN of leaf laminae, due to higher nutrient acquisition, with strong correlation with nitrogen concentration, but AN of pitchers does not increase, despite increased nitrogen concentration in their tissue. Increased AN improves growth and reproduction and is likely to increase the competitive advantage of carnivorous over non-carnivorous plants in nutrient-poor habitats.

Progress in studying N cycling has been hindered by a lack of effective measurements "that integrate processes such as denitrification, competition for N between plants and microbes, and soil organic matter (SOM) decomposition over large time scales (years rather than hours or days). Here I show how long-term measurements of super(15)N in plants, microbes, and soil after a one-time addition of super(15)N ("labeled" N) can provide powerful information about long-term N dynamics in a semiarid grassland. I develop a simple dynamic model and show that labeled-N fractions in plant and microbial-N pools (expressed as a fraction of total N in each pool) can change long after super(15)N application (.5 years). These super(15)N dynamics are closely tied to the turnover times of the different N pools. The model accurately simulated the labeled-N fractions in aboveground biomass measured annually during five years after addition of super(15)N to a semiarid grassland. I also tested the sensitivity of five different processes on labeled-N fractions in aboveground plant biomass. Changing plant/microbial competition for N had very little effect on the labeled-N fraction in aboveground biomass in the short and long term. Changing microbial activity (N mineralization and immobilization), N loss, or N resorption/re-translocation by plants affected the labeled-N fraction in the short term, but not in the long term. Large long-term effects on the labeled-N fraction in aboveground biomass could only be established by changing the size of the active soil-N pool. Therefore, the significantly greater long-term decline in the labeled-N fraction in aboveground. biomass observed under elevated CO sub(2) in this grassland system could have resulted from an increased active soil-N pool under elevated CO sub(2) (i.e., destabilization of soil organic matter that was relatively recalcitrant under ambient CO sub(2) conditions). I conclude that short- and long-term labeled-N fractions in plant biomass after a super(15)N pulse are sensitive to processes such as N mineralization and immobilization, N loss, and soil organic matter (de-)stabilization. Modeling these fractions provides a useful tool to better understand N cycling in terrestrial ecosystems.

Three Casuarina tree species, Casuarina glauca, Casuarina cunninghamiana and Casuarina equisetifolia, native to Australia, are naturalized in Florida, USA. Many Florida Casuarina trees are considered unidentifiable, presumably due to interspecific hybridization. We collected tissue from over 500 trees from Australia and Florida and genotyped these using amplified fragment length polymorphisms. Our goal was to determine the exact identity of the Florida species, including any putative hybrid combinations. In Australia, we found high assignment values to the three parental species, and no evidence of hybridization. In Florida, we found many trees with strong assignment to any one of the three species, as well as 49 trees with assignment values intermediate to C. glauca and C. equisetifolia, suggesting hybridization between these species. One population of 10 trees had assignment values intermediate to C. cunninghamiana and C. glauca, suggesting additional hybridization. For 69 of these putative hybrid and parental types, we sequenced a low-copy intron of nuclear G3pdh, and these sequences indicated that some Florida trees contain heterozygotic combinations of C. glauca and C. equisetifolia haplotypes. The presence of novel hybrids in the Florida invasion may enhance evolution of invasive traits in these species. Novel Casuarina hybrids in Florida have no coevolutionary history with any insects or diseases, which may be problematic for biological control efforts.

Using published descriptions of G. sabinae as the synonym of G. fuscum, type of the genus Gymnosporangium, the Michigan specimen was identified and confirmed by comparison with previously reported European and U.S. specimens (BPI 118736 and BPI 856578). The diagnostic characteristics of G. sabinae include: spermagonia epiphyllous; aecia hypophyllous, roestelioid, 3 to 6 mm high; peridium balanoid (acorn shaped), becoming elongated at maturity, pale yellow, sides opening with lateral slits but remaining attached at light brown, pointed apex; peridial cells elongated, 51 to 68 urn long, outer walls smooth, inner walls and side walls sparsely echinulate; aeciospores globose to broadly ellipsoid, somewhat angular, surface slightly coronate, 22 to 32 x 22 to 36 km, walls orange, 3.5 to 5.5 km thick. This species is distinguished from other species of Gymnosporangium on Pyrus by the balanoid (acorn-shaped) peridium and the late season maturation of the aecial stage. Telia and teliospores of G. sabinae are produced on the alternate host, various species of Juniperus sect. Sabinae, but were not observed in Michigan. The specimen from Michigan is deposited in the U.S. National Fungus Collections (BPI 878928). G. sabinae is widely distributed in Europe, extending to Asia and North Africa, but is rarely reported in North America. It was accidentally introduced into California in the aecial stage on P. communis L. and the telial stage on Juniperus chinensis L., as well as introduced into Canada (British Columbia). The only previous report of G. sabinae on P. calleryana is in Germany. G. sabinae is known to attack commercial pear and ornamental juniper plants in Europe, thus it seems important to prevent the further spread of this fungus in North America.

For example, Oregon contains 100,000 ha of land infested with L. draba (2). Because it is capable of aggressive spread and has the potential to reduce the value of wheat-growing land (4), it is the target of biological control research. The application of multiple pathogens has been advocated for control of other brassicaceous weeds, including the simultaneous application of biotrophic and necrotrophic pathogens (3). In pursuit of this approach, in 2007, we discovered the occurrence of leaf spots on approximately 90% of L. draba plants near Shepherd, MT, which were distinct from leaf lesions caused by Cercospora bizzozeriana (1). The lesions were initially tiny, black spots enlarging over time to become circular to irregular and cream-colored around the initial black spots and sometimes with dark brown borders or chlorotic halos. Conidia from the lesions were light brown, elongate and obclavate, produced singly from short conidia, with 8 to 12 transverse septa, and 2 to 6 longitudinal septa. The spore body measured 25 to 35 x 200 to 250 urn with a beak cell 42 to 100 km long. On the basis of conidial and cultural characteristics, the fungus was identified as Alternaria brassieae (Berk.) Sacc. Leaf tissues bordering lesions were plated on acidified potato dextrose agar. Colonies on V8 and alfalfa seed agar were black with concentric rings, eventually appearing uniformly black after 10 to 14 days. The internal transcribed spacer region of rDNA was amplified using primers ITS1 and ITS4 and sequenced. BLAST analysis of the 575-bp fragment showed a 100% homology with a sequence of A. brassieae Strain B from mustard (GenBank Accession No. DQ156344). The nucleotide sequence has been assigned GenBank Accession No. FJ869872. For patho-genicity tests, aqueous spore suspensions approximately 10 super(5)/ml were prepared from cultures grown at 20 to 25C for 10 to 14 days on V8 agar and sprayed on leaves of three L. draba plants. Inoculated plants were enclosed in plastic bags and incubated at 20 to 22C for 72 to 80 h. In addition, three plants of the following reported hosts of A. brassicae were inoculated: broccoli, canola, Chinese cabbage, collards, broccoli raab, kale, mustard greens, radish, rape kale, and turnip. Within 10 days, leaf spots similar to those described above developed on plants of radish, canola, Chinese cabbage, and turnip and A. brassicae was reisolated and identified. Control plants sprayed with distilled water remained symptomless. These inoculations were repeated and results were the same. To our knowledge, this is the first report of a leaf spot disease caused by A. brassicae on L. draba in North America. A voucher specimen has been deposited with the U.S. National Fungus Collections (BPI No. 878750A).

The presence of rings suggested the possible involvement of one or more viruses. Nucleic acid from seven of eight symptomatic tubers received in Washington (cvs. FL1867 and FL1922) tested positive for Tomato spotted wilt virus (TSWV) by reverse transcription (RT)-PCR with primers TSWV 1 and 2 (3). Similarly, tubers (cvs. FL1867 and FL2053) received in North Dakota tested positive for TSWV with forward (S1983) and reverse (S2767) primers of Tsompana et al. (4). The 777-bp amplicon obtained with primers TSWV 1 and 2 and the 803-bp amplicon obtained with primers S1983 and S2767 were cloned and three clones of each were sequenced. Analysis of the consensus sequences and BLAST comparisons confirmed the Washington and North Dakota sequences were indeed TSWV in origin and were each 98 to 99% identical to the corresponding nucleocapsid region of a number of TSWV isolates and most closely related to an isolate detected in eastern black nightshade from Colorado (GenBank No. AY777475). The deduced ammo acid sequences of the 777-bp nucleocapsid open reading frame differed from AY777475 at only two residues in each of the Washington and North Dakota sequences. The Washington and North Dakota derived sequences were deposited with GenBank (Nos. FJ882069 and FJ882070, respectively). None of the eight symptomatic tubers tested positive for Tobacco rattle virus (TRV), Alfalfa mosaic virus (AMV), or the necrotic strains of Potato virus Y (PVY) by RT-PCR. Mechanical transmission tests were conducted by grinding symptomatic tissue of a TSWV-positive FL1867 tuber in 10 volumes of 30 mM potassium phosphate buffer, pH 8.0, containing 10 mM of sodium diethyldithiocarbamate and 10 mM of sodium thioglycollate and rub inoculated onto Carborundum-dusted leaves of Samsun NN tobacco. Approximately 10 days after inoculation, chlorotic-necrotic rings were present on the inoculated leaves and circular necrotic lesions developed on the upper leaves. Dark stem lesions were also present on inoculated tobacco, and after 3 weeks, the upper leaves developed severe, spreading lesions. Tissue from the symptomatic tobacco tested positive for TSWV by RT-PCR (primers TSWV 1 and 2) and also with a TSWV-specific ImmunoStrip (Agdia, Inc., Elkhart, IN), but tested negative for TRY, AMV, and PVY by RT-PCR. TSWV has been reported on field-grown potatoes in North Carolina (1) and has been reported on potatoes in Australia (2) and in other parts of the world (referenced in 1). To our knowledge, this is the first report associating TSWV with tuber necrosis on potatoes in Texas.

The winter of 2006-2007 was particularly warm producing higher bud development scores for several of the genotypes and an apparent decrease of cold hardiness. Significant differences in LT50 values (treatments causing 50% bud mortality) were observed among the genotypes in both years, with a significant clone x year interaction. The greatest range in LT50 values occurred in 2007, when values ranged from -11.9 degree C for 'Millennia' to -25.5 degree C for 'Reveille', two southern highbush cultivars. Results suggest that germplasm selected in North Carolina might typically have sufficient cold hardiness to be used without concern as parental material in the development of blueberry germplasm with northern adaptation. Other more southern germplasm was generally less hardy and, if utilized as parental material, the resulting progeny would require greater scrutiny with regard to cold hardiness.

Diseased plants were localized mainly in two rows in a section of the greenhouse and produced no fruits or only fruits with reduced size. Leaf samples were collected from four individuals among numerous diseased plants in this greenhouse. Screening samples by ELISA, PCR, or reverse transcription (RT)-PCR for PepMV, Tomato spotted wilt virus, Tomato yellow leaf curl virus, Tomato torrado virus, Tomato apex necrosis virus, and Begomovirus, Tobamovirus, and Pospiviroid species showed that all four plants had a mixed infection of both PepMV and a pospiviroid. RT-PCR with the pospiviroid-specific primers Pospil-RE and Pospil-FW amplified the expected 196-bp products from these four samples. Each amplicon was cloned into the pCR4-TOPO vector (Invitrogen, Carlsbad, CA) and one individual cDNA clone from each isolate was sequenced. BLASTN analyses of nucleotide sequences of these clones showed 97 to 99% identity to Mexican papita viroid (MPVd) isolates currently in the NCBI Genbank. These four newly identified MPVd isolates were not identical; seven nucleotide substitutions or indels were identified in this region. The full viroid genome was obtained by RT-PCR in isolate VF2 with a new reverse primer MPVd-RE (5' GATCCCTGAAGCGCTCCT 3') in combination with the forward primer Pospil-FW. Using the same approach as stated above, this amplicon was cloned and sequenced. The nucleotide sequence of the 196-nt amplicon previously amplified and cloned from the isolate VF2 genome was identical to this region in the genomic clone. BLASTN analysis showed that the VF2 genome (GenBank Accession No. FJ824844) had >98% sequence identity to each of nine MPVd isolates (GenBank Accession Nos. L78454 and L78456-L78463), 94% identity to Tomato planta macho viroid (TPMVd) (GenBank Accession No. K00817) and 680% identity to Tomato chlorotic dwarf viroid (GenBank Accession Nos. EF582392-EF582393). Prior to this find, MPVd had been identified only in papita (Solanum cardiophyllum) in Mexico and is considered a possible ancestor of TPMVd, Potato spindle tuber viroid (PSTVd), and possibly of other PSTVd-group viroids now infecting crop plants. The origin of MPVd in this greenhouse facility in Delta, British Columbia is unknown. The infected plants were destroyed by the grower. The patho-genicity of MPVd isolates characterized in this study was not evaluated on tomato because of quarantine regulations governing this viroid in the United States. The identification of MPVd infecting an important agricultural crop (tomato) outside its center of origin in Mexico indicates a potentially important major shift in the epidemiology of MPVd. To our knowledge this is the first report of MPVd from tomato in Canada.

This scale allows for tight control of experimental variables, but systematically ignores the potential for regional-scale environmental variation to affect agronomic operations and thereby influence weed management outcomes. We quantified linkages among agronomic, environmental and weed management characteristics of 174 commercial sweet corn fields throughout the north central United States and evaluated crop and weed responses to these variables using classification and regression tree (CART) analysis. Multi-model selection indicated that characteristics of weed management systems, especially total cost and herbicide rate, were important predictors of weed diversity, interference and fecundity. Adding agronomic variables, such as planting date, or environmental variables, such as latitude, explained additional variation in weed floristic measures. We tested yield predictions of the most parsimonious CART model against a verification data set comprised of over 1500 published observations from 25 experiments conducted in the major North American regions where sweet corn is grown for processing. Yield values fell within the 95% confidence interval of observed data for most branches of the tree, suggesting the experimental and analytical approaches were reasonably robust. Several characteristics favoring sweet corn productivity and weed management sustainability were identified.

Temporal stability of surface and profile soil moisture data were investigated for 20 LWREW soil moisture measurement stations. In addition, daily surface and profile soil moisture measurements were obtained in four 800 m by 800 m fields (remote sensing footprint), including two rangeland sites and two winter wheat fields. The work aimed to analyze the temporal stability of soil moisture at the watershed and field scale and to identify stations within the watershed, as well as locations within each field, that were representative of the mean areal soil moisture content. We also determined the relationship between sites found to be temporally stable for surface soil moisture versus those determined stable for average profile soil moisture content. For the unusually wet experimental period, results at the watershed scale show that LWREW stations 133 and 134 provided stable underestimates, while stations 132 and 154 provided stable overestimates of the watershed mean at all depths. In addition, station 136 had very high non-zero temporal stability at the 25 cm and 45 cm depths indicating that it could be used as representative watershed site provided a constant offset value is used to acquire a watershed mean soil water content value. In general, the deeper depths exhibited higher soil moisture spatial variability, as indicated by the higher standard deviations. At the field scale, measured average profile soil moisture was higher in the winter wheat fields than the rangeland fields with the majority of the winter wheat depth intervals having high non-zero temporal stability. Field scale temporal stability analysis revealed that 4 of the 16 sampling sites in the rangeland fields and 3 of the 16 sampling sites in the winter wheat fields either under or overestimated the field means in the 0-5 and 0-60 cm depth intervals. Field sites considered temporally stable for the surface soil moisture were not stable for the profile soil moisture, except for the LW45 field where two sites were stable at both the surface and profile soil moisture. This finding is significant in terms of soil moisture ground-truth sampling for calibrating and validating airborne remotely sensed soil moisture products under extremely wet conditions. In addition, identification of temporally stable sites at the watershed and field scales in the LWREW provide insight in determining future measurement station locations and field scale ground sampling protocol, as well as providing data sets for hydrologic modeling.

In the first set of in vitro assays, when metabolites were compared based on initial bacterial cell count, X. bovienii (SN) metabolites generally exhibited the greatest suppression of phytopathogens and Xenorhabdus sp. (355) the least with Photorhabdus luminescens (Hb) and Xenorhabdus nematophila (All) being intermediate. In a second set of in vitro assays, in which metabolites were compared at 50 mg per ml acetone, P. luminescens (VS) exhibited greater suppression than P. luminescens (Hb), Photorhabdus sp. (MX4), X. bovienii (SN), and Xenorhabdus sp. (3 - 8b). In in vivo tests, 6 or 12% dilutions of X. bovienii (SN) or P. luminescens (Hb) metabolites caused 90 - 100% suppression of P. cactorum lesions on pecan leaves with only slight phytotoxicity. No phytotoxic effects were observed in detached peach leaves at dilutions up to 25%. Metabolite treatments, derived from X. bovienii (SN) and P. luminescens (Hb), were also tested for suppression of F. effusum sporulation in detached pecan shoots. Reductions in sporulation caused by bacterial metabolites were similar to those following treatment with two chemical fungicides, dodine and fenbuconazole; a third chemical triphenyltin hydroxide had no effect. Further research is warranted to determine if fungal or oomycete incited diseases in pecan and peach can be controlled with metabolites of Xenorhabdus spp. and Photorhabdus spp. JF - Archives of Phytopathology and Plant Protection AU - Shapiro-Ilan, David I AU - Reilly, Charles C AU - Hotchkiss, Michael W AD - USDA-ARS, Southeastern Fruit and Tree Nut Research Lab, Byron, GA Y1 - 2009/08// PY - 2009 DA - Aug 2009 SP - 715 EP - 728 PB - Taylor & Francis, 11 New Fetter Lane London EC4P 4EE UK, [mailto:info@tandf.co.uk], [URL:http://www.tandf.co.uk] VL - 42 IS - 8 SN - 0323-5408, 0323-5408 KW - Microbiology Abstracts B: Bacteriology; Microbiology Abstracts C: Algology, Mycology & Protozoology; Microbiology Abstracts A: Industrial & Applied Microbiology KW - Phytophthora cactorum KW - Plant protection KW - Monilinia fructicola KW - Glomerella cingulata KW - Sporulation KW - Leaves KW - Metabolites KW - Pathogens KW - Triphenyltin KW - Oomycetes KW - Prunus KW - Shoots KW - Photorhabdus KW - Photorhabdus luminescens KW - Xenorhabdus KW - Fungicides KW - Xenorhabdus nematophila KW - Phytotoxicity KW - Acetone KW - Phomopsis KW - J 02410:Animal Diseases KW - K 03410:Animal Diseases KW - A 01360:Plant Diseases UR - http://libproxy.lib.unc.edu/login?url=http://search.proquest.com/docview/20645562?accountid=14244 L2 - http://vb3lk7eb4t.search.serialssolutions.com/?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQ%3Amicrobiologyb&rft_val_fmt=info:ofi/fmt:kev:mtx:journal&rft.genre=article&rft.jtitle=Archives+of+Phytopathology+and+Plant+Protection&rft.atitle=Suppressive+effects+of+metabolites+from+Photorhabdus+and+Xenorhabdus+spp.+on+phytopathogens+of+peach+and+pecan&rft.au=Shapiro-Ilan%2C+David+I%3BReilly%2C+Charles+C%3BHotchkiss%2C+Michael+W&rft.aulast=Shapiro-Ilan&rft.aufirst=David&rft.date=2009-08-01&rft.volume=42&rft.issue=8&rft.spage=715&rft.isbn=&rft.btitle=&rft.title=Archives+of+Phytopathology+and+Plant+Protection&rft.issn=03235408&rft_id=info:doi/10.1080%2F03235400701390539 LA - English DB - ProQuest Environmental Science Collection N1 - Date revised - 2009-06-01 N1 - Last updated - 2015-03-30 N1 - SubjectsTermNotLitGenreText - Shoots; Plant protection; Fungicides; Leaves; Sporulation; Phytotoxicity; Metabolites; Triphenyltin; Acetone; Pathogens; Phytophthora cactorum; Xenorhabdus; Photorhabdus luminescens; Photorhabdus; Monilinia fructicola; Glomerella cingulata; Xenorhabdus nematophila; Oomycetes; Prunus; Phomopsis DO - http://dx.doi.org/10.1080/03235400701390539 ER - TY - JOUR T1 - Germination arrest factor (GAF): Part 2. Physical and chemical properties of a novel, naturally occurring herbicide produced by Pseudomonas fluorescens strain WH6 AN - 20635196; 9374221 AB - Pseudomonas fluorescens isolate WH6 and several related isolates have been shown previously to produce and secrete a novel, naturally occurring herbicide that arrests germination of the seeds of a large number of grassy weed species. The physical and chemical characteristics of this Germination Arrest Factor (GAF) have been investigated in the present study. GAF was insoluble in all organic solvents tested with the exception of methanol, in which it was moderately soluble. However, appropriate concentrations of aqueous ethanol solutions could be used to extract GAF from dried WH6 culture filtrates. GAF activity was destroyed by heating at temperatures in excess of 65 [degree]C, but no obvious loss of activity was observed after exposure for several hours at room temperature to either acid or alkaline conditions within the pH range 2- 12. GAF activity in the culture filtrate gradually declined during prolonged storage at 4 [degree]C. Ultrafiltration and gel filtration studies indicated that GAF activity was associated with a compound or compounds having a molecular weight less than 1000. As expected from its solubility properties, GAF activity did not bind to reverse-phase materials (e.g., silica-C[sub]18 cartridges). The very hydrophilic character of the GAF molecule suggests that it does not contain an aromatic ring structure. GAF was retained on an anion exchange column, indicating that the active molecule must contain an acid group.

Biological control literature contains controversial evidence for the impact of increased predator species diversity and habitat manipulation on prey suppression. We investigated the individual and combined effects of two predator species (Coleomegilla maculata (DeGeer) and Lebia grandis Hentz) on the herbivore Leptinotarsa decemlineata (Say) in potato fields with and without rye mulch. In surveys of the endemic populations we detected that C. maculata is approximately 16 times more abundant than L. grandis and the two predator species responded in opposite manner to the habitat manipulation treatment in potato fields: on average 35% of all C. maculata but 85% of all L. grandis collected over two field seasons were found in tilled plots vs. rye mulched plots. In field cages we investigated the effect of mulching and predator identity on L. decemlineata suppression. Neither predator was influenced significantly by the presence of rye mulch. L. grandis was effective in suppressing the target prey relative to the control but C. maculata in the single species as well as in the two-species assemblages was not consistently able to suppress prey relative to the control. This study found no support for positive multi-predator effects since the two predator species assemblages performed as predicted based on the results from individual predators. Practical implications of this study suggest focusing conservation biological control efforts on L. grandis to maximize its density in L. decemlineata infested potato fields.

Several commercial formulations of glyphosate were found to be compatible for tank mixing with M. verrucaria, including Touchdown and RoundUp HiTech. Others, such as Accord XRT II and RoundUp WeatherMAX killed all the spores of M. verrucaria immediately after mixing at only 10% the maximum labeled application rate. Many herbicides, which were not suitable for co-application with M. verrucaria, did not inhibit the growth of the fungus when added directly to media at up to 1% concentration, indicating that these products could be compatible with M. verrucaria as sequential applications in an integrated weed management system. Several commercially available spray adjuvants and polyoxyethylene tridecyl ether (TDA) formulations were tested in vitro for their efficiency in dispersing spores and in a plant bioassay for bioherbicidal activity. All of the products improved the activity of M. verrucaria over the water-only treatments and TDA formulations with a hydrophilic-lipophilic balance (HLB) number of 8 or 10 had the highest activity. The mechanism for improved bioherbicidal activity with these adjuvants was investigated in vitro, and TDA HLB 8 and 10 did not significantly improve conidia dispersal or accelerate spore germination relative to other surfactants. It is possible that the role of the surfactant is in the alteration of the plant cuticle or otherwise preparing the infection court. Better adjuvant selection and integration with affordable synthetic herbicides should aid in the development of more cost-effective biological control of weeds.

Several management systems (Status Quo, Soil Conserving, Soil Improving (SI), Disease Suppressive, and Continuous Potato) were evaluated for their effects on early blight potential under irrigated and rainfed conditions. In 2006 and 2007, microclimatic data at the canopy level were recorded with a data logger. Early blight incidence and severity was determined by visually assessing symptoms. Disease incidence and lesion numbers varied among cropping systems and between years. Disease incidence ranged from 31 to 64% (2006) and 12 to 43% (2007), and was significantly higher with the Continuous Potato system than with Disease Suppressive, Status Quo, Soil Conserving, and SI systems. The relationships of incidence and disease severity with microclimate varied and were mostly non-significant, suggesting that the chosen variables were not reflective of pathogen development. Incidence was significantly associated with cropping systems. Disease prediction based on the Tom-Cast model was not correlated with observed disease levels. This research demonstrated that early blight disease is enhanced through continuous potato production.

To better understand the dynamics of soil total organic carbon (TOC) and phosphorus (P) during beef cattle pastures to wetland reconversion, soil core samples were collected from the beef cattle pasture and from the natural wetland at Plant City, FL, during five summer seasons (2002-2007). The levels of TOC and soil P were significantly affected by changing land use and hydrology. Draining natural wetlands to grazed pastures resulted in very pronounced reduction of TOC from 180.1 to 5.4gg super(-) super(1). Cumulative concentrations of total phosphorus (TP) in soils (1134mgkg super(-) super(1)) under drained condition are two to three times lower than those in soils (2752mgkg super(-) super(1)) under flooded condition over the periods of land use reconversion. There was a declining trend (r=0.82**; p?0.01) in total soil P from natural wetland (763mgkg super(-) super(1)) to altered pastures (340mgkg super(-) super(1)), largely as organic-bound P (natural wetland, 48%; grazed pastures, 44%; altered pastures, 29%). These results are important in establishing baseline information on soil properties in pasture and wetland prior to restoring and reconverting pasture back to wetland conditions. The results further suggest that changes in soil properties due to changing land use and hydrologic conditions (drying and re-wetting) could be long lasting.

Understanding the natural variation of soybean seed proteins is necessary to evaluate potential unintended (collateral) effects due to transgenic modifications in genetically modified (GMO) soybeans. We used two-dimensional polyacrylamide gel electrophoresis (2D-PAGE), matrix-assisted laser desorption/ionization time of flight (MALDI-TOF) mass spectrometry, and liquid chromatography coupled to tandem mass spectrometry (LC-MS/MS) to separate, identify and quantify the different classes of soybean seed proteins. Sixteen soybean genotypes, including four wild and twelve cultivated genotypes, belonging to four different subgroups were used as models for protein profile evaluation. Significant variations of allergen and anti-nutritional protein profiles were observed between two different groups, cultivated and wild soybean genotypes. However, only minor variations in protein profiles were observed within the soybean samples from the same group (cultivated or wild). These results may be useful to scientists needing to compare GMO and non-GMO soybeans once additional data are generated on additional soybean varieties and the same varieties grown at different geographical locations.

Because surface-applied litter is completely exposed to the atmosphere, runoff can transport nutrients into nearby streams and lakes, and much of the ammonium nitrogen volatilizes before it can enter the soil. Our previous research showed that a manual knifing technique to apply dry litter under a perennial pasture surface effectively prevented about 90% of nutrient loss with runoff from surface-applied litter, and tended to increase forage yield. However, this technique (known as subsurface banding) cannot become a practical management option for producers until it is mechanized. To begin that process, we tested an experimental single-shank, tractor-drawn implement designed to apply poultry litter in subsurface bands. Our objective was to compare this mechanized subsurface-banding method against conventional surface application to determine effects on nutrient loss with runoff from a perennial grassland treated with dry poultry litter. Early in the growing season, broiler litter was applied (6.7 dry-weight Mgha super(-) super(1)) to each plot (except three control plots) using one of two application methods: surface broadcast manually or subsurface banded using the tractor-drawn implement. Simulated rainfall (5cmh super(-) super(1)) generated 20min of runoff from each plot for volume and analytical measurements. Results showed that subsurface-banded litter increased forage yield while decreasing nutrient (e.g. N and P) loss in runoff by at least 90% compared to surface-broadcast litter.

However, few studies have evaluated the risks and benefits of nonionic surfactant applications in row-crop agricultural systems. The objective of this study was to evaluate the impact of a nonionic surfactant on cotton (Gossypium hirsutum L.) production on a Faceville loamy sand (fine, kaolinitic thermic Typic Kandiudult) in the coastal plain region of Georgia. The experiment consisted of two components: (1) on-site rainfall simulation and (2) agronomic cotton field trials. Treatments were designed to test the impact of rate and frequency of surfactant applications using six combinations of application rates and timings. For the rainfall simulation component, only the control (0DT0 L ha-1) and high rate (0DT51 L ha-1) of surfactant applications were evaluated. During the field trial, soil water content, cotton stand counts, and yield were measured. Rainfall simulations showed that the addition of surfactant increased runoff, decreased infiltration, and promoted surface sealing. Despite the demonstrated potential for water loss, agronomic field trials showed that crop yields were not significantly different between surfactant-treated and untreated plots. No differences in soil water content were observed between treatments at 5 and 15 cm depths; however, soil water content was significantly higher in untreated control plots at the 30 cm depth. Data demonstrate the need for clarification of soil physical/chemical properties and surfactant interactions that may lend themselves to the creation of surface seals and how these seals impact soil/water conservation and crop yield.

The superposition of static and dynamic controls can lead to different soil moisture patterns for a given catchment during wetting, draining, and drying periods. These relationships can be further complicated in snow-dominated mountain regions where soil water input by precipitation is largely dictated by the spatial variability of snow accumulation and melt. In this study, we assess controls on spatial and temporal soil moisture variability in a small (0.02 km super(2)), snow-dominated, semi-arid catchment by evaluating spatial correlations between soil moisture and site characteristics through different hydrologic seasons. We assess the relative importance of snow with respect to other catchment properties on the spatial variability of soil moisture and track the temporal persistence of those controls. Spatial distribution of snow, distance from divide, soil texture, and soil depth exerted significant control on the spatial variability of moisture content throughout most of the hydrologic year. These relationships were strongest during the wettest period and degraded during the dry period. As the catchment cycled through wet and dry periods, the relative spatial variability of soil moisture tended to remain unchanged. We suggest that the static properties in complex terrain (slope, aspect, soils) impose first order controls on the spatial variability of snow and resulting soil moisture patterns, and that the interaction of dynamic (timing of water input) and static influences propagate that relative constant spatial variability through most of the hydrologic year. The results demonstrate that snow exerts significant influence on how water is retained within mid-elevation semi-arid catchments and suggest that reductions in annual snowpacks associated with changing climate regimes may strongly influence spatial and temporal soil moisture patterns and catchment physical and biological processes.

AN - 67492810; 19545150 AB - A fungal endophyte ( Undifilum oxytropis ) has been implicated in the synthesis of swainsonine in Oxytropis and Astragalus species, commonly known as locoweeds. A quantitative PCR method has been developed to measure the amount of endophyte in Oxytropis and Astragalus species. The limit of quantitation was estimated to be 0.2 pg of endophyte/ng of total DNA. This method of analysis was used to quantify the amount of endophyte in 10 plants each of Oxytropis sericea (white point locoweed), Astragalus mollissimus (wooly locoweed), and Astragalus lentiginosus (spotted locoweed). A significant amount of individual plant variability was observed in endophyte content among individuals in all three species. In one O. sericea and one A. lentiginosus plant swainsonine concentrations were near or below the limit of detection. These plants also had the lowest amounts of endophyte when compared to the other specimens.

13267723 AB - Reducing emissions of volatile organic compounds (VOCs) from fumigant pesticides is mandatory in California, especially in 'nonattainment areas' like the San Joaquin Valley that do not meet federal air quality standards. A two-year field study was conducted to examine the feasibility of site-specific fumigant application only at future tree sites with dramatically reduced amounts of fumigant chemicals on an orchard basis. Soil gas distribution and atmospheric emission of 1,3-dichloropropene and chloropicrin were measured after applying InLine using subsurface drip irrigation. It was predicted that, except in the surface 20 cm of soil, satisfactory pest control could be achieved within a 15 cm radius from the injection point. Also, at radial distances of 15-51 cm from the point of fumigant injection, effective nematode control may be achieved. Cumulative atmospheric emission of the fumigants was estimated to be 18-23% of the applied active ingredients in plots that had been cover cropped with Sudan grass and 2-6% in plots that had remained bare for several months before treatment. Considering the significantly small amount of fumigant used on an orchard basis, the spot drip fumigation may achieve a 10-fold reduction in atmospheric VOCs load from fumigant pesticides.

The objective was to determine the impact of rotational grazing on GIN infection of weaned lambs. In year 1, naturally infected Katahdin lambs (120 days of age) were randomly assigned to graze (1) continuous bermudagrass (CB; n = 14), (2) rotational bermudagrass moved every 3.5 days and returned to original plot 35 days later for three rotations (RB; n = 14), or (3) rotational bermudagrass rotated when forage height fell below 10 cm (RBH; n = 7) where first day of grazing = Day 0. In late summer, all lambs were supplemented with 500 g corn/SBM because of poor condition. The following year, similar animals were used and included the CB (n = 18) and the RB (n = 36) groups only. In both years, fecal egg counts (FECs) and blood packed cell volume (PCV) were determined every 7-14 days and body weight every 28 days. Individuals were dewormed with 0.5 g copper oxide wire particles (COWP) when FAMACHA score increased to 3 or more. Between 0 and 3 deworming treatments per lamb were necessary and there tended to be fewer RB than CB lambs dewormed by Day 84 for both years combined (P < 0.001). Worm free tracer lambs were introduced to CB (n = 6) and RB (n = 8) plots following the last rotation during the first year to determine worm burdens after 20 days of grazing. Abomasal worm burden tended to be greater in RB than CB or RBH tracer lambs (P < 0.10), but intestinal worm numbers were similar. Differences may be due to differences in grazing patterns among groups. Body weight gains were similar between CB and RB groups. Economic value between the CB and RB lambs was similar based on number of lambs that could have been marketed as organic. For both years, lambs relied exclusively on COWP for GIN control with the exception of one lamb. In summary, while there was a reduced incidence of deworming in the RB compared with the CB group of lambs, estimated economic value of these systems was similar.

AN - 67429225; 19416969 AB - Cry toxins produced by the bacterium Bacillus thuringiensis are effective biological insecticides. Cadherin-like proteins have been reported as functional Cry1A toxin receptors in Lepidoptera. Here we present data that demonstrate that a coleopteran cadherin is a functional Cry3Aa toxin receptor. The Cry3Aa receptor cadherin was cloned from Tenebrio molitor larval midgut mRNA, and the predicted protein, TmCad1, has domain structure and a putative toxin binding region similar to those in lepidopteran cadherin B. thuringiensis receptors. A peptide containing the putative toxin binding region from TmCad1 bound specifically to Cry3Aa and promoted the formation of Cry3Aa toxin oligomers, proposed to be mediators of toxicity in lepidopterans. Injection of TmCad1-specific double-stranded RNA into T. molitor larvae resulted in knockdown of the TmCad1 transcript and conferred resistance to Cry3Aa toxicity.

Extensive research into habitat needs (primarily for roosting) of reproductive females during the previous 2 decades has produced a wealth of information useful for developing conservation strategies for this group in their summer roost areas. However, the ecological needs of males, non-reproductive females, and juveniles have received far less attention, as have the ecological needs of all bats outside the pup-rearing season. Hence, it is unlikely that a single paradigm could comprehensively address conservation needs of all demographic groups within a species because they may have different seasonal distributions, reproductive strategies, and thermoregulatory needs. Herein, we recommend research into a wider spectrum of demographic groups and seasons to form a more holistic vision of the conservation needs of bats. We urge greater attention to understanding thermo-energetic and reproductive underpinnings of observed patterns of seasonal distribution and habitat selection by bats in the USA. Such understanding is instrumental for development of scientifically sound conservation strategies to confront emerging threats to conservation of bats in the 21st century: climate change, disease, habitat degradation, and environmental contaminants. We discuss interconnections among these emerging threats and the fundamental need to incorporate understanding of thermo-energetic strategies of bats in development of conservation strategies or legislation to mitigate potential impacts on bat populations of the USA.

We investigated the long-term impacts of these settlement-era activities on understory plant communities by comparing understory composition at a historically logged and grazed site to that of an environmentally similar site which was protected from past use. We found that species richness and cover within functional groups rarely differed between sites in either upland or riparian areas. Multivariate analyses revealed little difference in species composition between sites on uplands, though compositional differences were apparent in riparian zones. Our findings suggest that settlement-era logging and grazing have had only minor long-term impacts on understories of upland Front Range P.ponderosa-P.menzi esii forests, though they have had a greater long-term influence on riparian understories, where these activities were likely the most intense.

Ecologically based strategies that include controlling snakeweed and reestablishing desirable herbaceous species are needed to restore productivity and diversity to invaded areas. The objective of this study was to compare the ability of selected introduced and native grass species and prostrate kochia (kochia) to prevent reinvasion of snakeweed, downy brome, and annual forbs following control. This field study was replicated at two sites (Howell and Nephi, Utah) within the sagebrush-steppe biome. Snakeweed and downy brome were controlled by picloram (0.25 kg/ha [0.22 lb/ac]) and glyphosate (1.5 kg/ha [1.3 lb/ac]). The seeding treatments were comprised of three introduced grasses and a mix of these species, three native grasses and a mix of these species, and kochia. The treatments were seeded into 3 by 15-m (10 by 50 ft) plots in October 2003. Frequency and biomass of seeded species, snakeweed, downy brome, other grasses, and annual forbs were measured in 2004, 2005, and 2008. Seeded species were evaluated for success of establishment and persistence, and their ability to restrict reinvasion of snakeweed, downy brome, and annual forbs. Crested wheatgrass and big squirreltail had the best initial establishment at both locations (>75%). In contrast, kochia and Russian wildrye did not establish well at either site, and western wheatgrass did not establish well at Nephi. Snakeweed reestablishment was restricted in all treatments except the kochia treatments, in which kochia did not establish well. Frequency of downy brome increased at both sites, and annual forb frequency increased at Nephi to near 100%, but the better established grasses suppressed biomass production of these weedy species. Crested wheatgrass established best, had the greatest production, and provided greatest suppression of downy brome and annual weeds.

Although extensively studied in the southern and interior west, northwestern (Oregon, Washington, and Idaho) distribution and habitat information for tamarisk is either limited or lacking. We obtained distribution data for the northwest, developed a habitat suitability map, and projected changes in habitat due to climate change in a smaller case study area using downscaled climate data. Results show extensive populations of tamarisk east of the Cascade Mountains. Despite the perceived novelty of tamarisk in the region, naturalized populations were present by the 1920s. Major population centers are limited to the warmest and driest environments in the central Snake River Plain, Columbia Plateau, and Northern Basin and Range. Habitat suitability model results indicate that 21% of the region supports suitable tamarisk habitat. Less than 1% of these areas are occupied by tamarisk; the remainder is highly vulnerable to invasion. Although considerable uncertainty exists regarding future climate change, we project a 2- to 10-fold increase in highly suitable tamarisk habitat by the end of the century. Our habitat suitability maps can be used in "what if" exercises as part of planning, detection, restoration, management, and eradication purposes.

The effect of modifying the proportion of these two ingredients in a Noctuidae-specific diet was investigated utilizing the tobacco budworm Heliothis virescens (F.) (Lepidoptera: Noctuidae), with the goal of developing a suboptimal diet that, without drastically affecting this insect's growth and reproductive rates, could manifest subtle negative effects in this insect. The original diet formula contained 2.51% protein. When the proportions of soybean flour and wheat germ were changed to 2.15% protein the net reproductive rate of the first generation was significantly lower. In the second generation, the net reproductive rate, development time, percent female survivorship, fertility, intrinsic rate of increase, finite rate of increase and female longevity were significantly lower in both the 2.15% and 2.26% protein diets. The survival rate of immatures to the adult stage was 1% in the 2.05% protein diet in the first generation. Interestingly, females exposed to these suboptimal diets produced a significantly higher number of eggs but the survival of their larvae was significantly reduced. It is evident from these results that modifications to the protein content and the nutrient composition profile of the original wheat germ-based insect artificial formula can be used to produce subtle negative effects on the growth of tobacco budworm.

The impact of the endophytic fungus Trichoderma hamatum isolate DIS 219b on cacao's response to drought was studied. Colonization by DIS 219b delayed drought-induced changes in stomatal conductance, net photosynthesis, and green fluorescence emissions. The altered expression of 19 expressed sequence tags (ESTs) (seven in leaves and 17 in roots with some overlap) by drought was detected using quantitative real-time reverse transcription PCR. Roots tended to respond earlier to drought than leaves, with the drought-induced changes in expression of seven ESTs being observed after 7 d of withholding water. Changes in gene expression in leaves were not observed until after 10 d of withholding water. DIS 219b colonization delayed the drought-altered expression of all seven ESTs responsive to drought in leaves by .3 d, but had less influence on the expression pattern of the drought-responsive ESTs in roots. DIS 219b colonization had minimal direct influence on the expression of drought-responsive ESTs in 32-d-old seedlings. By contrast, DIS 219b colonization of 9-d-old seedlings altered expression of drought-responsive ESTs, sometimes in patterns opposite of that observed in response to drought. Drought induced an increase in the concentration of many amino acids in cacao leaves, while DIS 219b colonization caused a decrease in aspartic acid and glutamic acid concentrations and an increase in alanine and g-aminobutyric acid concentrations. With or without exposure to drought conditions, colonization by DIS 219b promoted seedling growth, the most consistent effects being an increase in root fresh weight, root dry weight, and root water content. Colonized seedlings were slower to wilt in response to drought as measured by a decrease in the leaf angle drop. The primary direct effect of DIS 219b colonization was promotion of root growth, regardless of water status, and an increase in water content which it is proposed caused a delay in many aspects of the drought response of cacao.

Currently there is no information available for the effect of coinfection by Ich and S. iniae on fish. The objective of this study was to determine the effects of parasite load and Ich development size on fish mortality following S. iniae infection. Low mortality (<20%) was observed in tilapia exposed to Ich or S. iniae alone. Mortalities increased from 38% in tilapia exposed to Ich at 10000 theronts fish super(-1) to 88% in fish at 20000 theronts fish super(-1) following S. iniae exposure. The median days to death were significantly fewer (7 d) in fish exposed to Ich at 20000 theronts fish super(-1) than fish exposed to 10000 theronts fish super(-1) (10 d). A positive correlation (correlation coefficient = 0.83) was noted between tilapia mortality and size of Ich trophonts at the time of S. iniae challenge. Fish parasitized with well-developed trophonts (Day 4, 2 x 10 super(7) km super(3) in volume) suffered higher mortality (47.5%) than fish (10.0%) infested by young trophonts (Hour 4, 1.3 x 10 super(4) km super(3) in volume) after S. iniae challenge. The results of this study demonstrated that both parasite load and trophont size increased susceptibility and mortality of tilapia to S. iniae infection.

The exposure assessment modeled stabilization, storage, and consumer preparation such as reheating and hot-holding. The model predicted that assuming a 10- or 100-fold increase from the assumed 1-log (maximal allowable) growth of C. perfringens results in a 1.2- or 1.6-fold increase of C. perfringens-caused illnesses, respectively, at the median of the uncertainty distribution. Improper retail and consumer refrigeration accounted for approximately 90% of the 79,000 C. perfringens illnesses predicted by the model at 1-log growth during stabilization. Improper hot-holding accounted for 8% of predicted illnesses, although model limitations imply that this is an underestimate. Stabilization accounted for less than 1% of illnesses. Efforts to reduce illnesses from C. perfringens in ready-to-eat and partially cooked meat and poultry products should focus on retail and consumer storage and preparation methods.

Inoculated subprimals that were not tenderized served as controls. Two core samples were removed from each of three tenderized subprimals and cut into six consecutive segments starting from the inoculated side. A total of six cores were also obtained from control subprimals, but only segment 1 (topmost) was sampled. Levels of E. coli O157:H7 recovered from segment 1 were 3.81 log CFU/g for the control subprimals and 3.36 log CFU/g for tenderized subprimals. The percentage of cells recovered in segment 2 was ca. 25-fold lower than levels recovered from segment 1, but E. coli O157:H7 was recovered from all six segments of the cores obtained from tenderized subprimals. In phase II, lean-side-inoculated (ca. 4.0 log CFU/g), single-pass tenderized subprimals were cut into steaks of various thicknesses (1.91 cm [0.75 in.], 2.54 cm [1.0 in.], and 3.18 cm [1.25 in.]) that were subsequently cooked on a commercial open-flame gas grill to internal temperatures of 48.8C (120F), 54.4C (130F), and 60C (140F). In general, regardless of temperature or thickness, we observed about a 2.6- to 4.2-log CFU/g reduction in pathogen levels following cooking. These data validate that cooking on a commercial gas grill is effective at eliminating relatively low levels of the pathogen that may be distributed throughout a blade-tenderized steak.

AN - 733364722; 19301244 AB - Cyclopamine, a steroidal alkaloid, from the plant Veratrum californicum is teratogenic, causing a range of different birth defects. The critical window for cyclopamine-induced synophthalmia formation has been reported to be gestational day (GD) 14. The objectives of this study were to better describe cyclopamine-induced craniofacial deformities, to better define the window of susceptibility to synophthalmia formation, and to characterize cyclopamine toxicokinetics in sheep. Ewes were dosed i.v. with purified cyclopamine for toxicokinetic analysis. Another four groups of ewes were dosed orally twice daily with 0.88 g/kg of V. californicum on GD 13, 14 or 15 or consecutively on GD days 13-15. Pregnancy and pre-partum fetal malformations were determined by ultrasound imaging on GD 60. At parturition lambs were assessed for gross malformations. The elimination half-life of cyclopamine in ewes was determined to be 1.1 +/- 0.1 h. The rapid clearance of cyclopamine indicates that ingestion of V. californicum must occur during a very narrow window for synophthalmia formation to occur. Ewes dosed with V. californicum on GD 13 or 14 had lambs with various craniofacial malformations including cyclopia, maxillary dysplasia and mandibular micrognathia. Ewes dosed on GD 15 delivered normal lambs. Ewes dosed consecutively on GD 13-15 were not pregnant at GD 60 and Veratrum-induced embryonic death was assumed to be the cause. Interestingly, lambs with cyclopia were smaller, under-developed and appeared premature even though their twin appeared fully developed. Initial evaluations suggest this was due to placental dysplasia. 2009 by John Wiley & Sons, Ltd.

AN - 733095302; 19272462 AB - The purposes of these experiments were to determine possible relationships among certain indices of lipid metabolism and specific gene expression in chickens (Gallus gallus) fed methimazole (MMI) and the subsequent effects of providing supplemental T3 to relieve the effects of MMI. Male, broiler chickens growing from 14 to 28 days of age were fed diets containing 18% crude protein and either 0 or 1 g MMI/kg of diet. At 28 days, birds received 18% crude protein diets containing either 0 or 1 mg triiodothyronine (T3)/kg. Birds were sampled at 0, 1, 2 & 4 days post relief from MMI or at 0, 3, 6, 9, 24 & 48 h. Measurements taken in the first experiment included in vitro lipogenesis (IVL), malic enzyme (ME), isocitrate dehydrogenase (ICDNADP), aspartate aminotransferase (AST) enzyme activities and the expression of the genes for ME, fatty acid synthase (FAS) and acetyl coenzyme carboxylase (ACC), ICD and AST. The same enzyme activities and gene expressions were assayed over the intervals mentioned above. In vitro lipogenesis was eliminated due to constraints imposed by sampling times. Gene expression was estimated with real time RT-PCR assays. Dietary MMI decreased IVL and ME at 28 days of age. T3 supplementation for 1 day restored both IVL and ME. Continuing T3 replenishment decreased IVL without affecting ME activity. Although MMI decreased ME gene expression, there was only a transitory relationship between enzyme activity and gene expression when apparent thyroid function was restored with exogenous T3. Metabolic changes in response to feeding T3 occurred within a short period, suggesting that changes in intermediary metabolism preceded morphological changes. Furthermore, the thyroid state of the animal will determine responses to exogenous T3. JF - Comparative biochemistry and physiology.

AN - 67580894; 19681280 AB - Internalization of Escherichia coli O157:H7 into spinach plants through root uptake is a potential route of contamination. A Tn7-based plasmid vector was used to insert a green fluorescent protein gene into the attTn7 site in the E. coli chromosome. Three green fluorescent protein-labeled E. coli inocula were used: produce outbreak O157:H7 strains RM4407 and RM5279 (inoculum 1), ground beef outbreak O157:H7 strain 86-24h11 (inoculum 2), and commensal strain HS (inoculum 3). These strains were cultivated in fecal slurries and applied at ca. 10(3) or 10(7) CFU/g to pasteurized soils in which baby spinach seedlings were planted. No E. coli was recovered by spiral plating from surface-sanitized internal tissues of spinach plants on days 0, 7, 14, 21, and 28. Inoculum 1 survived at significantly higher populations (P < 0.05) in the soil than did inoculum 3 after 14, 21, and 28 days, indicating that produce outbreak strains of E. coli O157:H7 may be less physiologically stressed in soils than are nonpathogenic E. coli isolates. Inoculum 2 applied at ca. 10(7) CFU/ml to hydroponic medium was consistently recovered by spiral plating from the shoot tissues of spinach plants after 14 days (3.73 log CFU per shoot) and 21 days (4.35 log CFU per shoot). Fluorescent E. coli cells were microscopically observed in root tissues in 23 (21%) of 108 spinach plants grown in inoculated soils. No internalized E. coli was microscopically observed in shoot tissue of plants grown in inoculated soil. These studies do not provide evidence for efficient uptake of E. coli O157:H7 from soil to internal plant tissue.

AN - 67578345; 19681269 AB - Clinical associations between Crohn's disease in humans and Mycobacterium avium subsp. paratuberculosis (MAP) have been suggested but not confirmed. Cattle could be sources for MAP, but little information on MAP prevalence with beef has been reported. Samples of ileocecal lymph nodes and swabs of hides and carcasses from 343 animals at cull cattle slaughtering facilities and 243 animals at fed cattle slaughtering facilities across the United States were analyzed for the presence of MAP. Amplification of genetic sequences detected MAP DNA predominantly on hides and in lymph nodes of samples taken at both types of processing facilities. More than 34% of the cattle at cull cow slaughtering facilities had ileocecal lymph nodes that tested positive for MAP DNA. From these same cattle, hide prevalence was more than twofold greater than the prevalence in ileocecal lymph nodes, suggesting that cross-contamination could be occurring during transport and lairage. The prevalence of MAP DNA decreased during processing, and less than 11% of the carcasses tested positive after interventions in the cull cow processing facilities. Using standard double-decontamination and culture techniques, less than 1% of the postintervention carcasses tested positive for viable MAP at cull cow facilities. In samples from the facilities processing only fed cattle, MAP prevalence of 1% or less was detected for ileocecal lymph node, hide, and carcass samples, and viable MAP was not detected. Based on this study, fed cattle carcasses are unlikely sources of MAP, and carcasses at cull cow plants have only a slight risk for transmitting viable MAP, due to current interventions.

AN - 67577572; 19681274 AB - Consumption of produce contaminated with Escherichia coli O157:H7 has resulted in cases of foodborne illness. We determined the efficacy of a mixture of three E. coli O157:H7-specific bacteriophages (ECP-100) in reducing the number of viable E. coli O157:H7 on contaminated fresh-cut iceberg lettuce and cantaloupe. E. coli O157:H7 was spot inoculated on lettuce pieces (9 cm2) with a population of 3.76 log CFU/cm2, allowed to dry, and then sprayed with a control (phosphate-buffered saline) or ECP-100 to deliver 7.98 log PFU/cm2 to lettuce stored for 2 days at 4 degrees C. Cut pieces of cantaloupe were spot inoculated with E. coli O157:H7 (4.55 log CFU/ml) and treated with the control or ECP-100 (6.69 log PFU/ml), and then stored at 4 or 20 degrees C for up to 7 days. On days 0, 2, 5, and 7, cantaloupe samples were homogenized, and populations of E. coli O157:H7 were enumerated. Populations of E. coli O157:H7 on lettuce treated with ECP-100 on 0, 1, and 2 days (0.72, <0.22, and 0.58 log CFU/cm2 of lettuce) and stored at 4 degrees C were significantly (P < 0.05) lower than those treated with the control (2.64, 1.79, and 2.22 log CFU/cm2), respectively. Populations on cut cantaloupes treated with ECP-100 on days 2, 5, and 7 (0.77, 1.28, and 0.96 log CFU/ml) and stored at 4 degrees C were significantly lower than those cut cantaloupes treated with the control (3.34, 3.23, and 4.09 log CFU/ml), respectively. This study is the first to show the effectiveness of bacteriophages to reduce E. coli O157:H7 on fresh-cut lettuce and cantaloupes.

AN - 67545479; 19645283 AB - Using quantitative polymerase chain reaction (QPCR), the relative transcriptional levels of cytochrome c oxidase subunit 3 (CO3) were studied in Aedes aegypti in response to treatment with acetone, permethrin, and fipronil. The transcriptional levels of CO3 were significantly (P < 0.05) higher in acetone-treated Ae. aegypti compared with that in untreated samples. Using ribosomal L24, heat shock protein (HSP), and actin as reference genes, relative transcription levels of CO3 in acetone-treated Ae. aegypti were 2.88 +/- 0.38-, 2.60 +/- 0.60-, and 3.24 +/- 0.70-fold higher, respectively, compared with that in untreated mosquitoes. Transcriptional levels of CO3 were induced significantly higher (6.54 +/- 1.22-, 4.62 +/- 0.74-, and 9.47 +/- 3.71-fold, respectively) by permethrin at LD10 compared with acetone (P < 0.05). Taken together, our results suggest that overexpression of CO3 is tightly regulated in Ae. aegypti in response to xenobiotic treatment.

AN - 67459835; 19407984 AB - The necrotrophic root pathogens Rhizoctonia solani AG-8 and R. oryzae cause Rhizoctonia root rot and damping-off, yield-limiting diseases that pose barriers to the adoption of conservation tillage in wheat production systems. Existing control practices are only partially effective, and natural genetic resistance to Rhizoctonia has not been identified in wheat or its close relatives. We report the first genetic resistance/tolerance to R. solani AG-8 and R. oryzae in wheat (Triticum aestivum L. em Thell) germplasm 'Scarlet-Rz1'. Scarlet-Rz1 was derived from the allohexaploid spring wheat cultivar Scarlet using EMS mutagenesis. Tolerant seedlings displayed substantial root and shoot growth after 14 days in the presence of 100-400 propagules per gram soil of R. solani AG-8 and R. oryzae in greenhouse assays. BC(2)F(4) individuals of Scarlet-Rz1 showed a high and consistent degree of tolerance. Seedling tolerance was transmissible and appeared to be dominant or co-dominant. Scarlet-Rz1 is a promising genetic resource for developing Rhizoctonia-tolerant wheat cultivars because the tolerance trait immediately can be deployed into wheat breeding germplasm through cross-hybridization, thereby avoiding difficulties with transfer from secondary or tertiary relatives as well as constraints associated with genetically modified plants. Our findings also demonstrate the utility of chemical mutagenesis for generating tolerance to necrotrophic pathogens in allohexaploid wheat. JF - TAG. Theoretical and applied genetics.

AN - 67442219; 19566479 AB - To describe the simple elimination kinetics of methyllycaconitine (MLA) and deltaline and evaluate the heart rate response in cattle following oral administration of larkspur. 5 healthy Angus steers that were habituated to metabolism crates. Tall larkspur (Delphinium barbeyi) in the early flowering stage was collected, dried, and ground. Each steer received a single dose of larkspur that was equivalent to 10.4 mg of MLA/kg and 11.0 mg of deltaline/kg via oral administration. Steers were housed in metabolism crates during a 96-hour period following larkspur administration; heart rate was monitored continuously, and blood samples were collected periodically for analysis of serum MLA and deltaline concentrations as well as assessment of pharmacokinetic parameters. No overt clinical signs of poisoning developed in any steer during the experiment. Mean +/- SE heart rate reached a maximum of 79.0 +/- 5.0 beats/min at 17 hours after larkspur administration. Serum MLA concentration was correlated directly with heart rate. Mean times to maximal serum concentration of MLA and deltaline were 8.8 +/- 1.2 hours and 5.0 +/- 0.6 hours, respectively. Mean elimination half-life values for MLA and deltaline were 20.5 +/- 4.1 hours and 8.2 +/- 0.6 hours, respectively. Following larkspur administration in 5 healthy steers, maximum serum concentrations of MLA and deltaline were detected within 10 hours, and changes in serum MLA concentration and heart rate were correlated.

AN - 67405752; 19398299 AB - The antioxidant activity of fat- and water-soluble antioxidant nutrients and their interactions in physiologic concentrations were determined in an in vitro biological model system. Reconstituted human serum consisting of delipidized human serum (DHS) combined with phosphatidylcholine liposomes (PCL) was used to determine antioxidant activities of physiologic concentrations of antioxidant nutrients. Radicals were initiated with 2,2'-azobis(4-methoxy-2,4-dimethylvaleronitrile) (2mmol/L), and oxidation was monitored by 4,4-difluoro-5-(4-phenyl-1,3-butadienyl)-4-bora-3a,4a-diaza-s-indacene-3-undecanoic acid. Fat-soluble antioxidant nutrients were incorporated into the PCL prepared by sonication and suspended in DHS to avoid any interference by the endogenous fat-soluble antioxidants. Water-soluble antioxidants were added directly into the DHS. The oxidation kinetics were monitored every 5 min up to 210 min using a microplate reader (excitation wavelength 500 nm, emission wavelength 520 nm). We confirmed the synergistic protective effect of the combination of ascorbic acid (1-5 microM) and alpha-tocopherol (1-5 mircoM) against the oxidation of DHS with PCL. Furthermore, physiologic concentrations of 1) beta-carotene (0.1, 0.5 microM) and alpha-tocopherol (2.5, 5.0 microM), 2) beta-carotene (0.1, 0.5 microM) and ascorbic acid (2.5 microM), and 3) uric acid (10 uM) and alpha-tocopherol (2.5, 5.0 microM) synergistically protected oxidation of reconstituted human serum. The present study results suggest a wide antioxidant network between water- and fat-soluble antioxidant nutrients in a biological system, although their actions in vivo warrant further study.

AN - 67389671; 19291696 AB - The efficacy of aerial electrostatic-charged sprays was evaluated for spray deposit characteristics and season-long control of sweet potato whitefly (SWF), Bemisia tabaci Genn. biotype B (aka B. argentifolii Bellows & Perring), in an irrigated 24 ha cotton field. Treatments included electrostatic-charged sprays at full and half active ingredient (AI) label rate, uncharged sprays and conventional sprays applied with CP nozzles at full label rate with several different insecticides. Spray droplet size was significantly smaller for electrostatic-charged sprays than for conventional sprays in top- and mid-canopy locations. The seasonal mean numbers of viable eggs and live large nymphs on cotton treated with electrostatic-charged sprays were comparable with those on cotton treated with conventional applications. Lethal concentration (LC(50)) for adults for electrostatic-charged sprays was comparable with that for conventional sprays. The amenability of electrostatic-charged sprays to a wide array of pesticides with different chemistries should be a useful tool in combating insect resistance. Results reported here suggest that the potential exists for obtaining increased efficacy against whiteflies using an electrostatic spray charging system, and that additional research will be required to improve charge-to-mass (Q/M) ratio in order to increase deposition of pest control materials to the lower surfaces of cotton leaves where the whiteflies reside.

AN - 67388955; 19360716 AB - Pyriproxyfen and hydroprene are insect growth regulators (IGRs) that have been evaluated to control insect pests of field crops, but there are limited reports of efficacy against stored-product insects. A laboratory study was conducted to determine residual efficacy of pyriproxyfen and hydroprene on wood, metal and concrete surfaces. Pyriproxyfen was applied to the surfaces at 1.15 and 2.3 mg active ingredient [AI] m(-2), while hydroprene was applied at the label rate of 19 mg AI m(-2). Late-instar larvae of Tribolium confusum Jacqueline DuVal, T. castaneum (Herbst), Oryzaephilus surinamenis L., Lasioderma serricorne (F.) and Plodia interpunctella (Hübner) were exposed with a food source on the treated surfaces. Residual testing was conducted at 1, 28 and 56 days post-treatment. Hydroprene was least persistent on concrete and generally most persistent on metal. Pyriproxyfen gave greater residual persistence than hydroprene, and there was no consistent difference in efficacy among the three surfaces. Efficacy varied among the five insect species, but generally P. interpunctella was the most tolerant species to both IGRs. Pyriproxyfen gave effective residual control of primary stored-product insect species by inhibiting adult emergence of exposed larvae. Results show that pyriproxyfen can be a useful addition for pest management programs in mills, warehouses and food storage facilities. (c) John Wiley & Sons, Ltd.

AN - 67385110; 19286813 AB - Ergot alkaloids have been associated with vasoconstriction in grazing livestock affected by the fescue toxicosis syndrome. Previous in vitro investigations studying how ergot alkaloids caused vasoconstriction have shown that ergovaline has a distinct receptor affinity and sustained contractile response. A similar contractile response has not been noted for lysergic acid. The objectives of this study were to determine if repetitive in vitro exposure of bovine lateral saphenous vein to lysergic acid or ergovaline would result in an increasing contractile response and if a measurable bioaccumulation of the alkaloids in the vascular tissue occurs over time. Segments of vein were surgically biopsied from healthy, Angus x Brangus cross-bred, fescue-naïve yearling heifers (n = 16) or collected from healthy mixed breed and sex cattle immediately after slaughter (n = 12) at a local abattoir. Veins were trimmed of excess fat and connective tissue, sliced into cross-sections, and suspended in a myograph chamber containing 5 mL of oxygenated Krebs-Henseleit buffer (95% O(2)/5% CO(2); pH = 7.4; 37 degrees C). Contractile responses to repetitive additions of ergovaline (1 x 10(-9) and 1 x 10(-7) M) and lysergic acid (1 x 10(-5) and 1 x 10(-4) M) were evaluated using the biopsied veins. For the bioaccumulation experiments, veins collected at the abattoir underwent repetitive additions of 1 x 10(-7) M ergovaline and 1 x 10(-5) M lysergic acid and the segments were removed after every 2 additions and media rinses for alkaloid quantification via HPLC/mass spectrometry. Contractile data were normalized as a percentage of contractile response induced by a reference dose of norepinephrine (1 x 10(-4) M). Repetitive additions of 1 x 10(-9) M ergovaline and 1 x 10(-5) and 1 x 10(-4) M lysergic acid resulted in contractile response with a negative slope (P < 0.02). In contrast, repetitive addition of 1 x 10(-7) M ergovaline resulted in a contractile response that increased with each addition (P < 0.01). Lysergic acid and ergovaline were detected at all 4 exposure levels (2x to 8x), but only the 1 x 10(-7) M ergovaline treatment resulted in increased tissue content as the number of exposures increased (P < 0.05). These data indicate that ergovaline, but not lysergic acid, bioaccumulates with repetitive exposure in vitro. These results suggest that ergovaline may have a greater potential for inducing toxicosis in grazing animals than lysergic acid because of its potential to bioaccumulate at the cellular site of action.

AN - 67161288; 19329307 AB - Stands of native grasses along roadways, in buffer strips, riparian zones and grass prairies have potential utility as feedstock for bioenergy production. The sustainability of harvesting these stands is reliant, in part, on knowledge of the mineral concentration of the harvested grasses because removal of mineral nutrients such as phosphorus (P) and potassium (K) can impact subsequent biomass production and ecosystem services associated with these stands. Mineral content of biomass, particularly that of silicon (Si), chlorine (Cl), and sulfur (S) also impacts thermochemical conversion approaches that convert grasses into bioproducts. This study quantified Cl, S, Si, P and K in Bromus marginatus, Elymus glaucus, Poa secunda, Pseudoroegneria, Elymus lanceolatus, Elymus trachycaulus, Leymus cinereus, Leymus triticoides, and Pseudoroegneria spicata collected at three growth developmental stages from four plant introduction stations located in the western US. Differences (P< or =0.05) in mineral concentrations were associated with developmental stage, species, and location. Variability was greatest in Si concentrations which ranged from 1847 to 28620 mg kg(-1), similar to those recorded in other grasses. Variability in Cl and S concentrations also occurred, but at less magnitude than that of Si. Concentrations of P and K, two mineral fertilizer components, varied approximately threefold among these grasses. Differences in mineral concentrations among these grasses were not completely dependent upon soil mineral content. Long-term evaluations of available soil mineral concentrations under contrasting management practices are needed to quantify how local conditions impact mineral cycling, and in turn, the sustainability of harvesting these stands. The data presented here establish baselines for these species in locations subject to contrasting environmental and microbiological conditions that affect mineral cycling and availability.

If true, energy balance partitioning and transpiration in woody ecosystems should be decoupled to an extent from rainfall, and sensitivity of the energy balance and evapotranspiration (ET) to rainfall and water deficits should be dampened. We evaluated responses of energy and water vapor fluxes to rainfall and water deficits in a live oak (Quercus virginiana)-Ashe juniper (Juniperus ashei) woodland on the karst Edwards Plateau, TX, USA, over a 2-year period using eddy covariance measurements of the turbulent fluxes. Total ET during the two years was 1416 mm, 92% of total rainfall. We observed large and rapid reductions in lambda E and increases in H during drying cycles, and high correlation between ET and soil water content in the upper 20 cm of the root zone. In most cases, ET declined at the same time as soil water content, indicating that the woodland relied heavily on water from recent rainfall events, rather than antecedent water. We found no evidence that deep roots were extracting significant amounts of water from a perennially stable supply of water. Excavations at the woodland site revealed a rock layer at 20 cm below the soil surface, with a dense root mat above the rock and penetration of relatively few roots into the rock through cracks and fissures. Thus, the most likely sources of water for trees were soil water and a limited supply of water stored in near-surface fractured rock layers.

Proteins from bacterial cell lysates were ionized by matrix-assisted laser desorption ionization (MALDI), mass isolated, and fragmented using a tandem time of flight (TOF-TOF) mass spectrometer. The sequence-specific fragment ions generated were compared to a database of in silico fragment ions derived from bacterial protein sequences whose molecular weights are the same as the nominal molecular weights of the protein biomarkers. A simple peak-matching and scoring algorithm was developed to compare tandem mass spectrometry (MS-MS) fragment ions to in silico fragment ions. In addition, a probability-based significance-testing algorithm (P value), developed previously by other researchers, was incorporated into the software for the purpose of comparison. The speed and accuracy of the software were tested by identification of 10 protein biomarkers from three Campylobacter strains that had been identified previously by bottom-up proteomics techniques. Protein biomarkers were identified using (i) their peak-matching scores and/or P values from a comparison of MS-MS fragment ions with all possible in silico N and C terminus fragment ions (i.e., ions a, b, b-18, y, y-17, and y-18), (ii) their peak-matching scores and/or P values from a comparison of MS-MS fragment ions to residue-specific in silico fragment ions (i.e., in silico fragment ions resulting from polypeptide backbone fragmentation adjacent to specific residues [aspartic acid, glutamic acid, proline, etc.]), and (iii) fragment ion error analysis, which distinguished the systematic fragment ion error of a correct identification (caused by calibration drift of the second TOF mass analyzer) from the random fragment ion error of an incorrect identification.

Systematic surveys using primarily enclosed track plates, with 10-km spacing, were conducted across a 27,700km super(2) area of largely forested, mountain terrain. Martens were detected at 20/184 (10.8%) of the sample units, aggregated in three distinct regions. We investigated habitat selection at multiple scales using circular assessment areas of 3, 20, and 80km super(2). The model for the largest assessment area best fit the data and included the following predictors: amount of reproductive habitat, number of habitat patches and land ownership category. These results support the hypothesis that martens select habitat based upon broad scale landscape conditions and that these conditions vary with ownership. We tested the model using an independent set of data, collected primarily during the winter. Poor fit of the test data in some locations raised concerns that our model, which was developed using data collected during the snow-free season, may not predict winter distribution well. We are investigating possible causes for the seasonal variation and until they can be incorporated our model represents a conservative view of marten habitat suitability based on summer occupancy. During the summer months, which is the reproductive season, martens are predicted to occur largely in relatively undisturbed landscapes where high-elevation, late-successional forests are common.

Endophyte-infected grass is tolerant to nematode, but the factors responsible are unknown. One objective of this work was to determine if root extracts of tall fescue effected chemoreceptor activity of Pratylenchus scribneri by using an in vitro chemoreception bioassay. Another objective was to determine if specific ergot alkaloids (ergovaline, ergotamine, a-ergocryptine, ergonovine), and loline alkaloids, all produced by the fungal endophyte, altered chemotaxis with this bioassay. Methanolic extract from roots altered chemotaxis activities in this nematode but only from roots of plants cultured 45 . d, which repelled nematodes. Extracts prepared from noninfected grasses were attractants. This assay indicated that the alkaloids were either repellents or attractants. N-formylloline was an attractant at concentrations of 20kg/ml and lower, while at higher concentrations it was a repellent. Ergovaline, the major ergot alkaloid produced by the endophyte, was repellent at both high and low concentrations and caused complete death of the nematodes.

A dual-frequency multisensor capacitance probe (MCP) is now commercially available, for sandy soils, to simultaneously monitor volumetric soil water content (VWC) measured as a percentage and salinity as a unitless volumetric ion content (VIC). The objectives of this research were to assess the relationship of salinity and water content with these dual-frequency MCPs under laboratory conditions, and assess its potential for field use in sandy soils of the mid-Atlantic region of the US. Water and salinity studies were conducted in two sand-filled PVC columns, 1.2m long by 0.25m ID. Each column was instrumented with ten dual-frequency capacitance sensors and two thermocouple temperature sensors. Four salinity levels were studied in the two columns using 0.5, 1, 2, and 4dSm super(-1) NH sub(4)NO sub(3) solutions. Water, salinity, and temperature readings were continuously recorded at 1-min intervals. The VIC values were found to be primarily qualitative, but combined with real-time VWC measures the probe could still be an important fertigation management tool to provide near-continuous real-time information on fertilizer penetration, spread and subsequent changes during crop growth.

Thermal inactivation followed a first order kinetic model in the temperature range tested. Temperature dependence of the first order inactivation rate constants could be accurately described by the Arrhenius equation, allowing Ea values to be calculated. Different milk systems did not show differences in enzyme thermo stability. The combined thermal (40, 50 and 60 C)-high hydrostatic pressure (300-450 and 600 MPa) effect on protease activity was studied. Protease was very resistant to high pressures. Pressure stability was higher in raw milk than in pasteurized milk; homogenization appeared to have a protective effect on the enzyme. The separate effects of pressure and temperature on enzyme inactivation were related to changes in L[low asterisk]-values and milk appearance. A very pronounced antagonistic effect between high temperature and pressure was observed, i.e. at temperatures where thermal inactivation at atmospheric pressure occurs rapidly, application of pressure up to 600 MPa exerted a protective effect. Industrial relevance - High hydrostatic pressure (HHP) is an emerging technology that has been successfully applied as a minimal process for a variety of foods. Although the potential for the use of HHP treatment as an alternative method to heat treatment of milk was proposed almost a century ago, the suitability of this innovative technology to extend the shelf-life of milk hinges not only on its ability to inactivate pathogenic vegetative microorganisms but also on its effectiveness to inactivate indigenous and endogenous enzymes. This work examines the combined effects of temperature, pressure and homogenization on the protease (exogenous enzyme from B. subtilis) activity in milk. Inactivation of protease could extend the shelf life of milk.

Many biological invasions likewise experience the phenomenon of decreasing population growth rates at low population densities because most founding populations of introduced nonnative species occur at low densities. In range expansion of established species, the initial colonizers of habitat beyond the organism's current range are usually at low density, and thus could be subject to Allee dynamics. There has been consistent empirical and theoretical evidence demonstrating, and in some cases quantifying, the role of Allee dynamics in the gypsy moth, Lymantria dispar (L.), invasion of North America. In this review, we examine the potential causes of the Allee effect in the gypsy moth and highlight the importance of mate-finding failure as a primary mechanism behind an Allee effect, while the degree to which generalist predators induce an Allee effect remains unclear. We then explore the role of Allee effects in the establishment and spread dynamics of the gypsy moth system, which conceptually could serve as a model system for understanding how Allee effects manifest themselves in the dynamics of biological invasions.

In this study, eight WEOM samples extracted with a 40:1 (v/w) water to sample ratio from alfalfa (Medicago sativa L.), corn (Zea mays L.), crimson clover (Trifolium incarnatum L.), hairy vetch (Vicia villosa L.), lupin (Lupinus albus L.), soybean (Glycine max L. Merr.), wheat (Triticum aestivum L.), and dairy manure were investigated using ultraviolet (UV)-visible, Fourier transform infrared (FT-IR), solution super(31)P nuclear magnetic resonance (NMR), and solid state super(13)C NMR spectroscopies. UV-visible and FT-IR spectra of the plant-derived WEOM samples were typical for natural organic matter, but possessed less humic-like characteristics than dairy manure-derived WEOM. Solution super(31)P NMR spectra indicated that WEOM samples extracted from alfalfa, corn, and soybean shoots contained both orthophosphate and monoester P. Of the monoester P in WEOM from soybean shoot, 70% was phytate P. WEOM from crimson clover, hairy vetch, lupin, and wheat shoots contained orthophosphate only. The solid-state super(13)C NMR spectra of the seven plant-derived WEOM samples indicated that they all were primarily composed of sugars, amino acids or peptides, and low molecular mass carboxylic acids. Carbohydrates were dominant components with very few aromatics present in these samples. In addition, WEOM from crimson clover and lupin, but not other three leguminous plant WEOM samples, contained significant asparagine. On the other hand, WEOM from corn and wheat contained less amino acids or peptides. The spectra of WEOM of dairy manure revealed the presence of significant amounts of nonprotonated carbons and lignin residues, suggesting humification of the manure-derived WEOM. Significant carbohydrates as well as aromatics were present in this WEOM. The P and C bonding information for these WEOM samples may be useful for understanding the effects of WEOM on soil nutrient availability to plants.

Irrigation development in the region accelerated during the 1950s. Both irrigated area and volume pumped peaked in 1974 and steadily declined during 1974-1989. By 2004, however, irrigated area was nearly the same as it was in 1958, and volume pumped had increased slightly. Several strategies to reduce groundwater withdrawals were reviewed without any reductions in irrigated land area or crop productivity. The most promising evaluated were: (1) increasing weather-based irrigation scheduling using the Texas High Plains Evapotranspiration Network (TXHPET); (2) converting gravity-irrigated land (27% of total) to centre pivot irrigation; and (3) replacing high-water to lower-water demand crops (i.e., corn to cotton). If the land area using the TXHPET network was doubled, and if gravity-irrigated lands were reduced to 10%, groundwater withdrawals could be reduced by 14%. An additional reduction of 8% may be possible by converting half of the irrigated corn area to cotton.

Relict cryogenic macrostructures have been described previously both within and outside the maximum extent of the Late Wisconsinan glacial border in many regions of the USA. The features were formed under climatic conditions associated with permafrost and periglacial conditions and provide evidence of climate change. In this study, buried relict cryogenic macrostructures were identified with GPR. On some two-dimensional GPR (2D GPR) records, boundaries with the host materials are indistinguishable or blurred resulting in the features being overlooked, misinterpreted and/or imprecisely delineated. Three-dimensional GPR (3D GPR) was able to delineate buried networks of sediment-filled wedges and provided more meaningful information than 2D radar records. When supplemented with adequate ground-truth observations, GPR offers considerable potential for imaging, interpreting and mapping near-surface cryogenic macrostructures in former periglacial environments.

During winters of 2004-2006, we compared bird density, foraging behavior, and bark beetle activity among burned treatment and unburned control units. Hairy woodpecker density was 5 times greater in burn units, whereas white-breasted nuthatches and pygmy nuthatches had similar densities between treatments. Compared to available trees, trees used by foraging hairy woodpeckers had 9 times greater odds of having bark beetles in control units and 12 times greater odds in burn units. Tree diameter appeared to be the main factor bark-foraging birds used in selecting winter foraging trees. Our results suggest that forest managers can use prescribed fire treatments without detrimental effects to wintering nuthatches, while providing additional food to hairy woodpeckers.

In accordance with Federal law, the operations were depopulated to prevent the spread of bTB. Subsequent wildlife surveillance programs identified high prevalence of M. bovis in mesocarnivores, including raccoons (Procyon lotor), which suggested that raccoons may be complicit in vectoring the pathogen among livestock operations. Our goal was to develop an empirical basis for generating hypotheses about the likelihood for raccoons to mediate the transmission of bTB to livestock. We found intersexual differences in scale-dependent resource selection and probability of spatial interaction that, under certain circumstances, may form the foundation for a sex-bias in disease transmission. Spatial dispersion of mixed-forest patches facilitated overlap of adjacent males, whereas female overlap zones included pastures. Within overlap zones, probabilities of interaction for male-male and male-female dyads were greater than for female-female dyads, although we documented an elevated likelihood of spatial interaction between raccoons and livestock around cattle-feeding troughs and water sources, regardless of sex. Partial regressions generated by linear models indicated that distance between nearest-neighbor mixed-forest patches explained most of this observed variation. These results supported our prediction that forest patches juxtaposed with anthropogenic features fostered social tolerance between males and, thus, facilitated spatial interaction and exploitation of anthropogenic features. In raccoons, sex and landscape composition influenced pathogen transmission potential. We suggest that livestock producers locate livestock feeding and watering features away from forest patches to mitigate future outbreaks of bTB in endemic areas.

(Lepidoptera: Noctuidae), is a polyandrous species of economic importance on the American continent. This sexual behavior allows for the presence of multiple spermatophores inside a female and the possibility of different males fertilizing the female's offspring, which can make insecticide resistance management or sterile insect release programs particularly challenging. The presence of spermatophores in a female can greatly influence her behavior, physiology, and offspring production. The role that these reproductive structures have is directly influenced by their size and the amount and type of substances that they contain as they are passed into the female during copulation. In this study, we investigated the role that male feeding has on mating potential, including the basic chemical composition and coloration of three sequentially produced spermatophores by male moths that were fed nothing, water, sucrose solution, or nectar. Male moth feeding had a direct influence on spermatophore weight, which was used as an indicator of polyandrous behavior. Nectar-fed moths produced heavier spermatophores and copulated in greater proportion than moths exposed to the other treatments. The total sugar and protein content of spermatophores was not influenced by the type of male feeding. Red or pink spermatophores were more prevalent in the first-produced spermatophores, diminishing in proportion on the second, and increasing again on the third-produced spermatophore, but this coloration proportion was prevalent of males not fed or fed only water. There were no differences in the chemical composition of the different colored spermatophores. These results indicate that polygynous behavior on H. virescens can be influenced by the type of male feeding.

Green Anole perch site, shrub species, and shrub volume preferences were also examined. We established two study plots of different shrub densities in open pine forests on the Angelina National Forest in eastern Texas. In late spring, the Green Anole population at the higher shrub-density plot was estimated to be 16 times greater than the population at the lower shrub-density plot. Green Anoles most commonly perched on live shrubs, but exhibited very little preference or avoidance of any particular species of live shrub or shrub-level vine. However, shrubs used by Green Anoles were 4-6 times greater in volume than plot averages.

Individuals were located once daily from 12 June to 14 August. We determined home-range size, movement distances, movement frequency, and habitat use for this short-term study. We also determined food habits of this population by examination of fecal samples. We compared these parameters to other Racer taxa in Utah (C. c. mormon [Western Yellow-bellied Racer]), Kansas (C. c. flaviventris [Eastern Yellow-bellied Racer]), and South Carolina (C.c. priapus [Southern Black Racer]). Compared to these populations, Texas Racers exhibited larger home ranges and greater movement frequency and distances during the summer than Utah or Kansas populations, but approximately equal to those of the South Carolina population. Available data on food habits suggests that all populations are consumers of invertebrate and vertebrate prey. We hypothesize that the basic diet of C. constrictor is composed of invertebrates captured by active foraging in areas of abundant herbaceous vegetation, that differences in home-range size and movement distances result from variations in patchiness of suitable foraging habitat across populations, and that the proportion of vertebrate prey in the diet of Coluber populations increases as home-range size and movement distances increase due to increasing patchiness of foraging habitat, resulting in increasing encounters with vertebrate prey.

They are known predators of Picoides borealis (Red-cockaded Woodpeckers), especially during the nestling phase. Picoides borealis cavities are frequently occupied by Southern Flying Squirrels, often several squirrels per cavity. Behavioral aspects of ratsnake predation on flying squirrels in woodpecker cavities is an important component required for a full understanding of the potentially complex interaction between Red-cockaded Woodpeckers, Southern Flying Squirrels, and ratsnakes. We induced previously captured Elaphe obsoleta (Texas Ratsnake) to climb boles of pine trees and gain access to Red-cockaded Woodpecker cavities known to contain Southern Flying Squirrels, and observed the resulting predatory interactions. Eight of nine ratsnakes successfully captured 14 of 22 Southern Flying Squirrels present in the cavities.

Whey protein isolate (WPI), a byproduct of the cheese industry, and gelatin, a byproduct of the leather industry, were reacted individually and in blends with microbial transglutaminase (mTGase) at pH 7.5 and 45 °C. When a WPI (10% w/w) solution was treated with mTGase (10 U/g) under reducing conditions, the viscosity increased four-fold and the storage modulus (G') from 0 to 300 Pa over 20 h. Similar treatment of dilute gelatin solutions (0.5-3%) had little effect. Addition of gelatin to 10% WPI caused a synergistic increase in both viscosity and G', with the formation of gels at concentrations greater than 1.5% added gelatin. These results suggest that new biopolymers, with improved functionality, could be developed by mTGase treatment of protein blends containing small amounts of gelatin with the less expensive whey protein.

Minor classes included cuticular inflations, protruding vulvar appendages of extruded gonadal tissues, vulval ridges, and peri-vulval pits. Vulval membranes were found in Mermithida, Triplonchida, Chromadorida, Rhabditidae, Panagrolaimidae, Tylenchida, and Trichostrongylidae. Vulval flaps were found in Desmodoroidea, Mermithida, Oxyuroidea, Tylenchida, Rhabditida, and Trichostrongyloidea. Epiptygmata were present within Aphelenchida, Tylenchida, Rhabditida, including the diverged Steinernematidae, and Enoplida. Within the Rhabditida, vulval ridges occurred in Cervidellus, peri-vulval pits in Strongyloides, cuticular inflations in Trichostrongylidae, and vulval cuticular sacs in Myolaimus and Deleyia. Vulval membranes have been confused with persistent copulatory sacs deposited by males, and some putative appendages may be artifactual. Vulval appendages occurred almost exclusively in commensal or parasitic nematode taxa. Appendages were discussed based on their relative taxonomic reliability, ecological associations, and distribution in the context of recent 18S ribosomal DNA molecular phylogenetic trees for the nematodes. Characters were found to be distributed across subsets of terminal and phylogenetically distant taxa, demonstrating considerable homoplasy. Accurate definitions, terminology, and documentation of the taxonomic distribution of vulval appendages are important in evaluations of hypotheses for either parallelism and developmental constraint or convergence and adaptation.

Houston Black clay was amended with four rates of arginine to vary microbial responses and keep other soil properties constant. The evolution of CO sub(2) during 1 and 3 days following rewetting of dried soil was highly related to CO sub(2) evolution during 10 days following chloroform fumigation (r super(2) = 0.92 and 0.93, respectively) which is a widely used method for soil microbial biomass C, which disrupts cellular membranes. This study suggest that the release of CO sub(2) following rewetting of dried soil with no amendments other than heat and water can be highly indicative of soil microbial activity and possibly be used as a quantitative measurement of soil biological quality in Houston Black soils.

The disease was originally observed in New Jersey and has now been reported in other blueberry growing regions in the United States, as well as several locations in Europe. A disease with similar symptoms occurs in American cranberry (V. macrocarpon), but BRRV has never been confirmed as the causal agent. Serological detection of BRRV in infected plants has been unsatisfactory. Using a primer set designed for routine detection (RRSV3/RRSV4), we successfully amplified a fragment of the virus from all tissues of infected highbush blueberry plants. Using the same primer set, we confirmed natural infection of BRRV in rabbiteye (V. virgatum) blueberry cultivars and the rabbiteye x V. constablaei hybrid cultivar Little Giant. These species have not been previously reported as hosts for this virus. Viral fragments were cloned from representative blueberry and cranberry plants exhibiting ringspot symptoms. Phylogenetic analysis of sequence data showed that cranberry strains of BRRV are precursors to the more derived blueberry strains. The techniques reported in this paper are being used to evaluate strain variation in Vaccinium species and to identify the as yet unknown vector(s) of this virus.

Macropore and matrix flow components were separated from total flow by a hydrograph-separation technique which used the assumption of dual porosity and a tracer mass balance. A mixture of potassium bromide was applied through a rain simulator to four plots in northern Mississippi in two rain events at 12.7 mm/h lasting 5 and 3 h separated by 6 h. The plots were either tilled or no-tilled with drains installed by two methods at the surface of the fragipan. The magnitude of water and bromide (Br super(-)) transported by macropore flow to a drain line were estimated and the resulting hydrographs provided an indication of the potential significance of macropore flow in transporting water and non-reactive chemicals through macropores to the shallow groundwater system. Matrix flow appears to contribute the majority of the water moving to the drains even during the early stages of the drain flow hydrographs. The no-till plots produced more macropore flow than the tilled plots, independent of how the drains were installed. Macropore flow in the drainage at any time was small as compared to the matrix flow; however it contributed a disproportionate amount of Br super(-) tracer. These data support the concept that models used to predict mass balances using only the matrix (Darcian) flow will underestimate those chemicals that move like bromide into the soil profile.

Most variants were recovered only once, but two were more widely distributed; one of these was a mild variant previously isolated in Germany, the second was a novel variant inducing symptoms similar to those of the type strain in tomato. Despite this apparent lack of population diversity, several informative PSTVd variants were recovered. Sequence changes in the pathogenicity and variable domains were particularly common, but previously unknown changes were also detected within the loop E motif in the central domain, a structural motif known to play a key role in PSTVd replication and host range determination.

In this study, CWR was used as a raw material to manufacture medium-density particleboard. The objective of this research was to characterize the mechanical and water resistance properties of CWR particleboards bonded by four different adhesive levels and compositions, including 4% polymeric methane diphenyl diisocyanate (PMDI), 2.8% PMDI, [1.2% rice bran adhesive (RBA) + 2.8% PMDI] and [20% recycled high-density polyethylene (HDPE) + 2.8% PMDI]. In addition, orthogonal experimental design was employed to optimize three factors (hot-press temperature, HDPE particle size and HDPE content) to achieve desired mechanical and water resistance properties of particleboards bonded by a mixture adhesive. The evaluated mechanical properties of particleboards were tensile strength (TS), modulus of rupture (MOR), modulus of elasticity (MOE), and internal bond (IB) strength. Water absorption (WA) and thickness swelling (THS) were measured to determine water resistance properties of the particleboards. Partially replacing PMDI with RBA did not compromise mechanical quality, but deteriorated water resistance properties. The results showed that 30% of PMDI can be replaced by adding 20% HDPE, resulting in particleboard with higher mechanical strength and water resistance than particleboard made without HDPE. It has been concluded that HDPE from recycled plastic bags could be used as an adhesive or additive to partially replace PMDI for making high-quality particleboards.

The use of by- products as precursors for the production of widely used adsorbents, such as activated carbons, may impart a value-added component of the overall biomass harvested. Our objective in this paper is to show how the partial oxidation of phosphoric acid-impregnated pecan shells resulted in activated carbons with different affinities for a typical metal ion, copper(II), in aqueous sorption studies. The oxygen level was varied during activation by altering the sweep gas (air) flow rate in the furnace. Surface area and micropore volume of the produced carbon did not vary significantly with degree of oxidation, while the surface charge and the adsorption capacity were strongly dependent on the oxidative conditions. Surface area functional groups of C[double bond; length as m-dash]O, aromatics, and phosphorus were confirmed by infrared spectroscopy. The results show that the yield of activated carbon product was higher in the more oxygen- deprived atmosphere but that the product had a lower affinity for adsorbing copper from an aqueous solution. The carbon with the highest adsorptive capacity was produced by activation in approximately 14% oxygen atmosphere, yielding adsorption values of 0.97 and 1.3 mmol of copper(II) per gram of carbon when the carbon had been in contact with a copper(II) solution with initial concentration of 10 and 20 mM of copper, respectively.

Seedlings of the early flowering Plant Introduction (PI) 251246 were inoculated in tubes with conidial suspensions of isolates of Verticillium dahliae from lettuce or cauliflower. PI 251246 developed significant leaf and root symptoms by 21 days following inoculation with isolates of race 1 and race 2 from lettuce, but not following inoculation with an isolate from cauliflower. In contrast, leaf symptoms on the cultivar La Brillante and root symptoms on the cultivar Salinas were not easily differentiated from the symptoms observed on the noninoculated control treatments in the soilless assay, even at the highest inoculum concentration of 1 x 10 super(7) conidia/ml. Comparison of the soilless growth chamber assay and a soil-based greenhouse assay revealed a significantly higher proportion of PI 251246 with root vascular discoloration in the soilless assay compared with the soil-based greenhouse assay (x super(2), 1 df = 8.9; P = 0.003). There is thus an advantage to using the soilless growth chamber assay with PI 251246. Compared with the soil-based greenhouse assay, the soilless assay reduced the time required for evaluation of Verticillium wilt symptoms on lettuce from about 90 days to 42 days.

Survival of CYSDV through the largely cucurbit-free winter months suggested the presence of weed or alternate crop hosts, although previous studies indicated a limited host range restricted to members of the Cucurbitaceae. To determine potential reservoir hosts for CYSDV in desert production, weed and crop hosts were collected from throughout the region over a period of 26 months, and were tested for the presence of CYSDV by reverse transcription-polymerase chain reaction (RT-PCR) using CYSDV HSP70h- and coat protein gene-specific primers. Many noncucurbits collected from infected melon fields and nearby areas were symptomless and virus free; however, CYSDV was detected in alfalfa (Medi-cago sativa), lettuce (Lactuca sativa), and snap bean (Phaseolus vulgaris), as well as in several weed species widely prevalent in the region. Typical crinivirus symptoms of interveinal yellowing and leaf brittleness were observed on CYSDV-infected snap bean, alkali mallow (Sida hederacea) and Wright's groundcherry (Physalis wrightii), while other infected crop and weed hosts were symptomless. Transmission tests demonstrated that lettuce, snap bean, alkali mallow, Wright's groundcherry, and buffalo gourd (Cucurbita foetidissima) could serve as virus reservoir hosts for transmission of CYSDV to melon and other cucurbits. These results expand the previously known host range of CYSDV, demonstrating that the virus is capable of infecting not only members of the Cucurbitaceae, but also plants in seven additional taxonomic families.

The effects of two fungicides and a plant growth regulator on in vitro pathogen characteristics and on canker expansion were investigated. In the first experiment, 16 single-spore isolates (11 P. citricola and 5 P. cactorum) were grown on clarified V8 juice agar amended with (i) 0 to 20 kg a.i./ml of mefenoxam, (ii) 0 to 301,429 kg a.i./ml phosphonate either with or without a bark-penetrating surfactant at 0.5 mg a.i./ml, or (iii) 0 to 25 mg a.i./ml of the surfactant alone. Radial growth, oospore production, and zoospore germination were observed to be dependent on isolate and treatment. A species effect on growth was also observed, as P. cactorum isolates were 2.5- to sevenfold less sensitive to phosphonate, but 2- to 150-fold more sensitive to mefenoxam than P. citricola isolates (based on 50% inhibition of growth). In the second experiment, bark and soil drenches of mefenoxam (50 mg a.i./ml and 19 kg a.i./ml, respectively), phosphonate (301,429 and 101 kg a.i./ml, respectively), and a soil drench of paclobutrazol (21 mg a.i./ml) were evaluated for their efficacy as curative or preventive treatments against bleeding canker. None of the treatments (curative or preventive) were able to stop canker expansion or prevent infection. However, saplings inoculated with P. citricola and treated with the phosphonate bark drench as either a curative or preventive treatment had cankers that were 36 to 82% shorter than those of inoculated control stems treated with water. For saplings inoculated with P. cactorum, the phosphonate bark drench was only effective when applied as a preventive (38% shorter than inoculated control stems treated with water), and not as a curative treatment. No other treatment was effective at limiting canker expansion.

After gathering 141 single-ascosporic B. graminis f. sp. tritici isolates from 10 eastern U.S. locations, 34 isolates from the United Kingdom, and 28 isolates from Israel, we analyzed pathogen population structure using presumptively neutral markers. DNA was extracted from conidia, primers for 12 "housekeeping" genes were designed, and amplicons were examined for polymorphism. Four genes were found to contain a total of 12 single-nucleotide polymorphisms in the U.S. population and were also analyzed in the U.K. and Israeli populations. In total, 25 haplotypes were inferred from the four concatenated genes, with 2 haplotypes comprising over 70% of the U.S. population. Using Hudson's tests and analysis of molecular variance, we found the wheat mildew isolates subdivided into four groups corresponding to distinct regions: the mid-Atlantic United States, the southern United States, the United Kingdom, and Israel. Genotypic diversity was greatest in samples from the United Kingdom, Israel, Virginia, and Kinston, NC. Using rarefaction, a procedure that compensates for differing sample sizes when estimating population richness and diversity, we found that cooler locations with greater conduciveness to regular powdery mildew epidemics had the greatest haplotype richness. Our results suggest that the eastern U.S. B. graminis f. sp. tritici population is young, descended recently from Old World populations with isolation and genetic drift, and is currently subdivided into northern and southern subpopulations.

Changing land-use strategies that would maintain standing forests may be among the least expensive of climate change mitigation options. Further, secondary tropical forests have been suggested to have great value for their potential to sequester atmospheric C. These options require an understanding of and capability to quantify C dynamics at landscape scales. Because of the diversity of physical and biotic features of tropical forests as well as approaches and intensities of land uses within the neotropics, there are tremendous differences in the capacity of different landscapes to store and sequester C. Major gaps in our current knowledge include quantification of C pools, rates and patterns of biomass loss following land-cover change, and quantification of the C storage potential of secondary forests following abandonment. In this paper we present a synthesis and further analyses from recent studies that describe C pools, patterns of C decline associated with land use, and rates of C accumulation following secondary-forest establishment--all information necessary for climate-change mitigation options. Ecosystem C pools of Neotropical primary forests minimally range from 6141 to 571 Mg/ha, demonstrating tremendous differences in the capacity of different forests to store C. Most of the losses in C and nutrient pools associated with conversion occur when fires are set to remove the slashed forest to prepare sites for crop or pasture establishment. Fires burning slashed primary forests have been found to result in C losses of 62-80% of prefire aboveground pools in dry (deciduous) forest landscapes and 29-57% in wet (evergreen) forest landscapes. Carbon emissions equivalent to the aboveground primary-forest pool arise from repeated fires occurring in the first 4 to 10 years following conversion. Feedbacks of climate change, land-cover change, and increasing habitat fragmentation may result in increases of both the area burned and the total quantity of biomass consumed per unit area by fire. These effects may well limit the capacity for future tropical forests to sequesterC and nutrients.

Sorption and transformation of IFT were investigated in laboratory incubations with four soils, and these results were used to interpret greenhouse studies using IFT to control several weed species. RESULTS: Degradation proceeded by previously observed pathways to form diketonitrile (DKN) and benzoic acid (BA) derivatives, as well as traces of unidentified products. Over the course of the incubation, DKN was the dominant active form of the herbicide present in the experimental system, and was thus critical to the soil activity of the herbicide for weed control. CONCLUSION: Control of most weed species appeared to be a function of both sorption and biodegradation of DKN, with greatest weed control being observed in soils in which a significant portion of the DKN that was formed persisted and remained bioavailable over the course of the incubation.

Current research efforts focus on replacing summer fallow in the region with more profitable and environmentally sustainable spring and summer crops. In the absence of reliable precipitation forecasts for the crop growing season, farmers rely mainly upon knowledge of plant available water (PAW) in the soil profile at planting for making crop choice decisions. To develop a decision support strategy for crop selection based on initial PAW, experiments were conducted with spring triticale (X Titicosecale Wittmack), proso millet (Panicum miliaceum L.), and foxtail millet (Setaria italica L. Beauv.) under artificially controlled Low, Medium, and High initial PAW levels during 2004 and 2005 at Akron, Colorado, and Sidney, Nebraska. The objectives of this study were to adapt an existing cropping systems model for the simulation of triticale and millet and to evaluate simulations from the adapted model by comparing results with field data collected under varying initial PAW conditions. The Root Zone Water Quality Model with DSSAT v4.0 crop growth modules (RZWQM2) was used. Specifically, the Cropping System Model (CSM)-CERES-Wheat module was adapted for simulating triticale, and CSM-CERES-Sorghum (v4.0) module was adapted for simulating proso millet and foxtail millet. Soil water, leaf area index, grain yield, and biomass data for the highest PAW treatment from one crop season for each of the three crops were used to adapt and calibrate the crop modules. The models were then evaluated with data from the remaining PAW treatments. The proso millet module was further tested with four years of data from a crop rotation experiment at Akron from 2003 to 2006. Simulation results indicated that the adapted and calibrated crop modules have the potential to simulate these new crops under a range of varying water availability conditions. Consequently, these models can aid in the development of decision support tools for the season-to-season management of these summer fallow replacement crops under dryland conditions in semi-arid environments.

AN - 20683689; 10061601 AB - BACKGROUND: Herbicide-resistant crop technology could provide new management strategies for the control of parasitic plants. Three herbicide-resistant oilseed rape (Brassica napus L.) genotypes were used to examine the response of attached Cuscuta campestris Yuncker to glyphosate, imazamox and glufosinate. Cuscata campestris was allowed to establish on all oilseed rape genotypes before herbicides were applied. RESULTS: Unattached seedlings of C. campestris, C. subinclusa Durand & Hilg. and C. gronovii Willd. were resistant to imazamox and glyphosate and sensitive to glufosinate, indicating that resistance initially discovered in C. campestris is universal to all Cuscuta species. Glufosinate applied to C. campestris attached to glufosinate-resistant oilseed rape had little impact on the parasite, while imazamox completely inhibited C. campestris growth on the imidazolinone-resistant host. The growth of C. campestris on glyphosate-resistant host was initially inhibited by glyphosate, but the parasite recovered and resumed growth within 3-4 weeks. CONCLUSION: The ability of C. campestris to recover was related to the quality of interaction between the host and parasite and to the resistance mechanism of the host. The parasite was less likely to recover when it had low compatibility with the host, indicating that parasite-resistant crops coupled with herbicide resistance could be highly effective in controlling Cuscuta.

These potentially adverse effects in grasslands may be mitigated by improved management practices. In pasture systems, the combined effects of poultry litter applications and interseeded rye (Secale cereale L.) on N sub(2)O emissions are still not well established. This study was conducted to estimate the magnitude of soil surface N sub(2)O fluxes as affected by interseeded winter rye forage, annually spring-applied composted turkey litter as well as by weather and soil parameters. Fluxes were measured by vented chambers during 2 yr in a bermudagrass (Cynodon dactylon [L.] Pers.) pasture in moderately well-drained Tonti gravelly silt loam (fine-loamy, active, mesic Typic Fragiudault) located in northwestern Arkansas, USA. During the 60 d following turkey litter applications, N sub(2)O fluxes were frequently well correlated with soil nitrate (NO sub(3) super(-); r: up to 0.82, P's < 0.05) implying substrate stimulation on soil N sub(2)O production. Likewise, rainfall patterns strongly influenced N sub(2)O fluxes. Large rainfalls of 91 and 32 mm occurred within 6 d prior to the maximum N sub(2)O flux means (263 and 290 kg N m super(-2) h super(-1), respectively). Treatment effects on N sub(2)O emissions were significant only in spring periods following manure addition, particularly in the second year of our study. In the spring of 2000, additions of composted turkey litter resulted in 1.5-fold increase in seasonal cumulative N sub(2)O emissions (P = 0.04) which was directly associated to a numerically greater soil NO sub(3) super(-). In the spring of 2001, soils planted to rye exhibited a pronounced significant effect on mitigating N sub(2)O emissions (30 vs. 112 mg N m super(-2); P = 0.04). During the winter and early spring, rye growth also decreased quantities of both soil NO sub(3) super(-) and water-filled pore space (WFPS) partly accounting for the lower N sub(2)O emissions in these fields. These results suggest that because poultry litter additions increased and interseeded rye diminished N sub(2)O emissions, the combined implementation of both management practices can produce environmental benefits while sustaining productivity in temperate pasture systems.

Hydrogen peroxide (H sub(2)O sub(2)) treatments (0.0, 15.6, 31.3, 62.5, 125, 250, 500, 1,000, 2,000, and 4,000 mg/L) were evaluated to determine their effect on channel catfish hatch rate (number of fry/number of eggs 100) and control of naturally occurring infestations of fungi Saprolegnia spp. in an experimental compartmentalized trough hatching system. Experiments were run at water temperatures of 23.2-24.0C, dissolved oxygen concentrations of 4.5-6.8 mg/L (53-79% saturation), total alkalinity of 209-217 mg/L, and total hardness of 91-110 mg/L. Treatments were applied to hatching compartments while well water was flowing at a rate of one water exchange every 30 min and egg density was 2.5 g eggs/L of water. Observations for fungal development were made daily, and the maximum measure of fungal growth was recorded. An initial range-finding study demonstrated that H sub(2)O sub(2) concentrations greater than 500 mg/L lowered the hatch rate. In later experiments, concentrations of 125, 250, and 500 mg/L applied for 6 d significantly increased the hatch rate and reduced fungal growth when compared with the controls.

Polyacrylamide (PAM) was added to sandy coastal plain soils to improve physical properties and yield. Soils were amended with linear and cross-linked PAMs. Treatments and controls included the following: (1) spraying a 600 mg kg super(-1) solution of linear PAM behind a subsoil shank at a rate of 3.93 kg ha super(-1), (2) spraying a 100 mg kg super(-1) solution at 0.66 kg ha super(-1), (3) spraying only water at 13.1 m super(3) ha super(-1), (4) dropping a dry PAM powder formulation (3005 KB) behind a subsoil shank at 300 kg ha super(-1), (5) dropping another dry PAM powder formulation (3005 K2) at 230 kg ha super(-1), (6) dropping a dry PAM powder formulation 3005 K2 at a lower rate of 55 kg ha super(-1), (7) applying nothing behind a subsoil shank, and (8) not subsoiling. In each of the 3 years of the experiment, new sets of treatments were set up while the old ones were maintained to look at longevity of the PAM effect. Though treatment effects were dominated by the tillage, the cross-linked PAMs were the only treatments more effective than tillage alone. The cross-linked PAMs may have been more effective because we could add more in dry form than in the spray form. The effect diminished with time similar to or faster than the results seen in tillage only. Though some PAM applications may have reduced cone indices, yields were not affected.

Large-scale oligonucleotide arrays for use in such analytical studies are currently under development; however, the implementation of this approach generally requires substantial time and financial resources. To address the need for a more accessible tool for fungal community profiling and broad diagnostics, we evaluated the potential utility of a reverse dot blot approach utilizing macroarray targets and probes that each consisted of a PCR product of the entire fungal ITS1-5.8S-ITS2 gene region. Samples used to generate the array targets included both culturable and non-culturable fungi and fungal-like protists representing a range of ecological functions. Tests performed using single-species probes within the genus Pythium demonstrated that taxonomic lineages could generally be distinguished when ITS DNA sequence similarity differed by greater than 5-10 %. An artificially constructed community probe of known composition successfully detected eight of the 10 lineages contained on the array with only one clear false positive in 95 targets. The approach was also successfully applied to environmental samples. Taxa resident in the soil of a local orchard were identified using the array and matched those documented in previous studies. Closely related taxa from a previously uncharacterized and geographically distant orchard soil were also identified by the array and had affinities to Leptodontium, Cadophora, Zalerion, and Geomyces. These taxa were further confirmed to be present in the sample by cloning and DNA sequencing. A minority of lineages had DNA targets with low melting temperatures which were not detected on the arrays except under conditions that compromised specificity. Membrane-based ITS macroarrays coupled with community ITS probes possessed sufficient power to detect multiple genus-level lineages of fungi in complex samples and should have broad applications in the study of fungal communities.

A species-specific primer LsoF was developed for both quantitative real-time PCR (qPCR) and conventional PCR (cPCR) to detect and quantify Lso in infected samples. In multiplex qPCR, a plant cytochrome oxidase (COX)-based probe-primer set was used as a positive internal control for host plants, which could be used to reliably access the DNA extraction quality and to normalize qPCR data for accurate quantification of the bacterial populations in environment samples. Neither the qPCR nor the cPCR using the primer and/or probe sets with LsoF reacted with other Liberibacter species infecting citrus or other potato pathogens. The low detection limit of the multiplex qPCR was about 20 copies of the target 16S rDNA templates per reaction for field samples. Lso was readily detected and quantified in various tissues of ZC-affected potato plants collected from fields in Texas. A thorough but uneven colonization of Lso was revealed in various tissues of potato plants. The highest Lso populations were about 3x10 super(8) genomes/g tissue in the root, which were 3-order higher than those in the above-ground tissues of potato plants. The Lso bacterial populations were normally distributed across the ZC-affected potato plants collected from fields in Texas, with 60% of ZC-affected potato plants harboring an average Lso population from 10 super(5) to 10 super(6) genomes/g tissue, 4% of plants hosting above 10 super(7) Lso genomes/g tissue, and 8% of plants holding below 10 super(3) Lso genomes/g tissue. The rapid, sensitive, specific and reliable multiplex qPCR showed its potential to become a powerful tool for early detection and quantification of the new Liberibacter species associated with potato ZC, and will be very useful for the potato quarantine programs and seed potato certification programs to ensure the availability of clean seed potato stocks and also for epidemiological studies on the disease.

AN - 20565821; 9265144 AB - The Southeast U.S. receives an average of 1300mm annual rainfall, however poor seasonal distribution of rainfall often limits production. Irrigation is used during the growing season to supplement rainfall to sustain profitable crop production. Increased water capture would improve water use efficiency and reduce irrigation requirements. Furrow diking has been proposed as a cost effective management practice that is designed to create a series of storage basins in the furrow between crop rows to catch and retain rainfall and irrigation water. Furrow diking has received much attention in arid and semi-arid regions with mixed results, yet has not been adapted for cotton production in the Southeast U.S. Our objectives were to evaluate the agronomic response and economic feasibility of producing cotton with and without furrow diking in conventional tillage over a range of irrigation rates including no irrigation. Studies were conducted at two research sites each year from 2005 to 2007. Irrigation scheduling was based on Irrigator Pro for Cotton software. The use of furrow diking in these studies periodically reduced water consumption and improved yield and net returns. In 2006 and 2007, when irrigation scheduling was based on soil water status, an average of 76mmha super(-) super(1) of irrigation water was saved by furrow diking, producing similar cotton yield and net returns. Furrow diking improved cotton yield an average of 171kgha super(-) super(1) and net return by $245ha super(-) super(1) over multiple irrigation rates, in 1 of 3 years. We conclude that furrow diking has the capability to reduce irrigation requirements and the costs associated with irrigation when rainfall is periodic and drought is not severe.

Increased water capture would efficiently improve water use and reduce irrigation amounts and other input costs, thus improving producer's profit margin. We quantified water capturing and erosional characteristics of furrow diking by comparing runoff (R) and soil loss (E) from furrow diked (DT) and non-furrow diked tilled (CT) systems. A field study (Faceville loamy sand, Typic Kandiudult) was established (2006 and 2007) near Dawson, GA with DT and CT systems managed to irrigated cotton (Gossypium hirsutum L.). Treatments included: DT vs. CT; DT with and without shank (+/- S); and rainfall simulation performed (0, 60 days after tillage, DAT). Simulated rainfall (50mmh super(-) super(1) for 1h) was applied to all 2mx3m plots (n=3). All runoff and E were measured from each flat, level sloping 6-m super(2) plot (slope=1%). Compared to CT, DT decreased R and E by 14-28% and 2.0-2.8 times, respectively. Compared to DT-S, DT+S decreased R and E by 17-56% and 26% to 2.1 times, respectively. Compared to sealed/crusted soil conditions at 60 DAT, simulating rainfall on a freshly tilled seedbed condition (DAT=0) decreased R by 69% to 3.4 times and increased E by 27%. DT0+S+RF0 plots (best-case scenario) had 2.8 times less R, and 2.6 times less E than CT-S+RF60 plots (worst-case). Based on $1.17ha-mm super(-) super(1) to pump irrigation water and $18.50ha super(-) super(1) for DT, a producer in the Coastal Plain region of Georgia would recover cost of DT by saving the first 16ha-mm of water. The DT+S system is a cost-effective management practice for producers in Georgia and the Southeastern U.S. that positively impacts natural resource conservation, producer profit margins, and environmental quality.

There is a lack of information on how the microclimate variability within silvopasture systems affects water requirements of forages. Small 26cm diameter, 23cm deep lysimeters planted with either orchardgrass (Dactylis glomerata L.) or tall fescue (Schedonorus phoenix (Scop.) Holub) were placed in the ground along the north and south edge of two 15m widex50m deep notches cleared into a mature second growth hardwood forest. One notch opened to pasture on the east receiving more early day solar radiation and one to pasture on the west receiving more wind and late day solar radiation. There was no significant difference in ET between orchardgrass and tall fescue. North edges, receiving more direct beam radiation, had significantly higher ET (39%) than south edges which received a higher percentage of diffuse radiation. The west notch had significantly higher ET (11%) than the east notch. At the sunniest sites, advection provided 20% of the energy used for ET while at the shadiest sites it provided more than half (56%) with the rest provided by incident solar radiation. Dates where photosynthetically active radiation (PAR) was restricted by clouds resulted in decreased ET relative to PAR compared to more sunny days. However, sites where PAR was restricted by tree shade had higher ET relative to PAR than more open sites. These results indicate tree modification of microclimate does not decrease forage ET to the extent that PAR is decreased.

It is often produced as part of a waste management plan with varying nutrient composition and energy characteristics on fields irrigated with livestock wastewater. The objective of this study was to determine the effect of subsurface drip irrigation with treated swine wastewater on both the quantity and quality of bermudagrass bioenergy. The treated wastewater was recycled from an advanced treatment system and used for irrigation of bermudagrass in two crop seasons. The experiment had nine water and drip line spacing treatments arrayed in a randomized complete block-design with four replicates. The bermudagrass was analyzed for calorific and mineral contents. Bermudagrass energy yields for 2004 and 2005 ranged from 127.4 to 251.4 MJ ha-1. Compared to irrigation with commercial nitrogen fertilizer, the least biomass energy density was associated with bermudagrass receiving treated swine wastewater. Yet, in 2004 the wastewater irrigated bermudagrass had greater hay yields leading to greater energy yield per ha. This decrease in energy density of wastewater irrigated bermudagrass was associated with increased concentrations of K, Ca, and Na. After thermal conversion, these compounds are known to remain in the ash portion thereby decreasing the energy density. Nonetheless, the loss of energy density using treated effluent via SDI may be offset by the positive influence of these three elements for their catalytic properties in downstream thermal conversion processes such as promoting a lesser char yield and greater combustible gas formation.

Corn ethanol processing creates the following products: 1/3 ethanol, 1/3 distillers grains, and 1/3 carbon dioxide. As the production of ethanol increases so does the generation of its coproducts, and viable uses continually need to be developed. A survey was mailed to operational US ethanol plants to determine current practices. It inquired about processes, equipment used, end products, and desired future directions for coproducts. Results indicated that approximately one-third of plant managers surveyed expressed a willingness to alter current drying time and temperature if it could result in a higher quality coproduct. Other managers indicated hesitation, based on lack of economic incentives, potential cost and return, and capital required. Respondents also reported the desire to use their coproducts in some of the following products: fuels, extrusion, pellets, plastics, and human food applications. These results provide a snapshot of the industry, and indicate that operational changes to the current production of DDGS must be based upon the potential for positive economic returns.

With these benefits in mind, the Data Uncertainty Estimation Tool for Hydrology and Water Quality (DUET-H/WQ) was developed from an existing uncertainty estimation framework for small watershed discharge, sediment, and N and P data. Both the software and its framework-basis utilize the root mean square error propagation methodology to provide uncertainty estimates instead of more rigorous approaches requiring detailed statistical information, which is rarely available. DUET-H/WQ lists published uncertainty information for data collection procedures to assist the user in assigning appropriate data-specific uncertainty estimates and then calculates the uncertainty for individual discharge, concentration, and load values. Results of DUET-H/WQ application in several studies indicated that substantial uncertainty can be contributed by each procedural category (discharge measurement, sample collection, sample preservation/storage, laboratory analysis, and data processing and management). For storm loads, the uncertainty was typically least for discharge (+/-7-23%), greater for sediment (+/-16-27%) and dissolved N and P (+/-14-31%) loads, and greater yet for total N and P (+/-18-36%). When these uncertainty estimates for individual values were aggregated within study periods (i.e. total discharge, average concentration, and total load), uncertainties followed the same pattern (Q < TSS < dissolved N and P < total N and P). This rigorous demonstration of uncertainty in discharge and water quality data illustrates the importance of uncertainty analysis and the need for appropriate tools. It is our hope that DUET-H/WQ contributes to making uncertainty estimation a routine data collection and reporting procedure and thus enhances environmental monitoring, modeling, and decision-making. Hydrologic and water quality data are too important for scientists to continue to ignore the inherent uncertainty.

Our objectives were to demonstrate that fungal laccase, a lignolytic copper-containing enzyme, can degrade cercosporin and reduce cercosporin toxicity toward living cells. Cercosporin from Cercospora beticola and Cercospora hayi was treated with laccase from basidiomycete fungi (Pleurotus os-treatus and Trametes versicolor) in the dark and under constant light. Under these conditions the absorbance of the cercosporin decreased at 220, 279 and 295-500 nm within 10 min of reaction with laccase from either P. ostreatus or T. versicolor, indicating that basidiomycete laccase can induce changes in UV-visible spectra of cercosporin. The LIVE/DEAD+ Bac Light VIABILITY kit and fluorescent microscopy showed more viable E. colt cells after incubation under light with cercosporin and laccase than with cercosporin alone. Lesions were apparent on sugar beet leaves exposed to cercosporin under light after 48 h, but leaves exposed to cercosporin and laccase showed visibly less damage. These data suggest that laccase from basidiomycete fungi can decrease the toxic effect of cercosporin toward microorganisms and plant tissue.

We investigated the fate of DIBOA in soil and DIBOA's effects on nematode reproduction. Soil in plastic bags was treated with DIBOA at concentrations ranging from 1.1 to 18 mu g g super(-1) dry soil, and with the root-knot nematode Meloidogyne incognita. Control soils were treated with water or with 0.31% methanol, with or without nematodes. DIBOA concentrations extracted from the soil were measured at selected times for 5 consecutive days. The soil from each bag was then placed into a pot in the greenhouse, and a cucumber seedling was transplanted into each pot. Five weeks later, only the highest DIBOA concentration, 18 mu g g super(-1) soil, reduced nematode egg numbers. At 0 h, DIBOA measured in soil ranged from 19.68 to 35.51% of the initial DIBOA concentration, and was dependent on the concentration added to the soil. DIBOA half-life was from 18 to 22 h, and very little DIBOA was present in soil after 120 h. Identified breakdown products accounted for only 4% at maximum of the initially added DIBOA. The results of our study demonstrate that high soil concentrations of DIBOA are necessary to suppress M. incognita; DIBOA may not be a major factor in nematode suppression by a rye cover crop.

Fish were exposed, under natural conditions, to Flavobacterium columnare, a ubiquitous bacterium associated with columnaris disease. During every time interval, the probability that a vaccinated fish would survive past time, t, was greater than for sham-vaccinated fish and survivor functions were significantly different (p-value <0.001). Overall, vaccinated fish had a 43% lower risk of death during the field trial. Overall incidence was 1.7 times greater for the sham-vaccinated (1.4%/d) as compared to the vaccinated fish (0.8%/d). Vaccination with AQUAVAC-COL (Intervet/Schering-Plough Animal Health) significantly reduced the risk of death from columnaris disease in feed-trained largemouth bass fry.

CP73-1547 and CP88-1508) were grown for 3 months in paired-companion, temperature-gradient, sunlit greenhouses under daytime [CO sub(2)] of 360 (ambient) and 720 (double ambient) mu mol mol super(-1) and at temperatures of 1.5 degree C (near ambient) and 6.0 degree C higher than outside ambient temperature. Leaf area and biomass, stem biomass and juice and CO sub(2) exchange rate (CER) and activities of ribulose bisphosphate carboxylase-oxygenase (Rubisco) and phosphoenolpyruvate carboxylase (PEPC) of fully developed leaves were measured at harvest. On a main stem basis, leaf area, leaf dry weight, stem dry weight and stem juice volume were increased by growth at doubled [CO sub(2)] or high temperature. Such increases were even greater under combination of doubled [CO sub(2)]/high temperature. Plants grown at doubled [CO sub(2)]/high temperature combination averaged 50%, 26%, 84% and 124% greater in leaf area, leaf dry weight, stem dry weight and stem juice volume, respectively, compared with plants grown at ambient [CO sub(2)]/near-ambient temperature combination. In addition, plants grown at doubled [CO sub(2)]/high temperature combination were 2-3-fold higher in stem soluble solids than those at ambient [CO sub(2)]/near-ambient temperature combination. Although midday CER of fully developed leaves was not affected by doubled [CO sub(2)] or high temperature, plants grown at doubled [CO sub(2)] were 41-43% less in leaf stomatal conductance and 69-79% greater in leaf water-use efficiency, compared with plants grown at ambient [CO sub(2)]. Activity of PEPC was down-regulated 23-32% at doubled [CO sub(2)], while high temperature did not have a significant impact on this enzyme. Activity of Rubisco was not affected by growth at doubled [CO sub(2)], but was reduced 15-28% at high temperature. The increases in stem juice production and stem juice soluble solids concentration for sugarcane grown at doubled [CO sub(2)] or high temperature, or at doubled [CO sub(2)]/high temperature combination, were partially the outcome of an increase in whole plant leaf area. Such increase would enhance the ongoing and cumulative photosynthetic capability of the whole plant. The results indicate that a doubling of [CO sub(2)] would benefit sugarcane production more than the anticipated 10-15% increase for a C sub(4) species.

Searching translated chicken genomic databases revealed many proteins homologous to mammalian SRs. SR mediated immune functions (oxidative burst, degranulation, phagocytosis, nitric oxide (NO) production, and cytokine expression) were evaluated in chicken heterophils, peripheral blood mononuclear cells (PBMC), and a chicken macrophage cell line (HD11) using various SR class A and B ligands. Results showed that the SR-A ligands, fucoidan, poly(I) and poly(G), but not SR-B ligands, phosphatidylserine and LDL, stimulated dose-dependent NO production in HD11 cells. However, SR-A ligands failed to induce NO in chicken monocytes. Quantitative RT-PCR indicated that SR ligands differentially regulated the gene expression of cytokines and chemokine in HD11 cells with a strong up-regulation of the cytokines IL-1 beta and IL-6 and the chemokine MIP-1 beta , but had no effect on IL-4, IL-12, IFN- gamma , and IFN- beta . SR-B ligands did not alter expression of these genes. SR-A ligands had no stimulatory effect on functional response in heterophils. However, LDL, a SR-B ligand stimulated oxidative burst in both heterophils and PBMC. Additionally, results indicate that SRs are involved in bacterial binding in macrophages.

In vivo monkey or kitten bioassays were developed for analysis of SEs emetic activity. To overcome the inherent limitations of such bioassays, this study describes an in vitro splenocyte proliferation assay based on SEs superantigen activity as an alternative method for measuring the activity of staphylococcal enterotoxin A (SEA). After incubation of splenocytes with SEA, `ell proliferation was measured by labeling the proliferating cells' DNA with bromodeoxyuridine (5-bromo-2-deoxyuridine, BrdU) and quantifying the incorporated BrdU by immunohistochemistry. BrdU labeling is shown to be highly correlated with SEA concentration (R2=0.99) and can detect 20 pg mL-1 of SEA, which is far more sensitive than most enzyme-linked immunosorbent assays. Our assay can also distinguish between active toxin and inactive forms of the toxin in milk. By applying immunomagnetic beads that capture and concentrate the toxin, our assay was able to overcome matrix interference. These results suggest that our in vitro cell-based assay is an advantageous practical alternative to the in vivo monkey or kitten bioassays for measuring SEA and possibly other SEs activity in food.

Its full life cycle was not discovered until 1970 when it was found that it is a coccidian parasite of cats with all non-feline warm blooded animals (including humans) as intermediate hosts. The discovery of the environmentally resistant stage of the parasite, the oocyst, made it possible to explain its worldwide prevalence. In the present paper, events associated with the discovery of its life cycle are recalled.
