TY - JOUR T1 - Protein tyrosine kinase and mitogen-activated protein kinase signalling pathways contribute to differences in heterophil-mediated innate immune responsiveness between two lines of broilers AN - 923204964; 15408819 AB - Protein tyrosine phosphorylation mediates signal transduction of cellular processes with protein tyrosine kinases (PTKs) regulating virtually all signalling events. The mitogen-activated protein kinase (MAPK) super-family consists of three conserved pathways that convert receptor activation into cellular functions: extracellular response kinases (ERK), c-Jun N-terminal kinases (JNK) and p38. Previously conducted studies using two chicken lines (A and B) show line A heterophils are functionally more responsive and produce a differential cytokine/chemokine profile compared with line B, which also translates to increased resistance to bacterial challenges. Therefore, we hypothesize the differences between the lines result from distinctive signalling cascades that mediate heterophil function. Heterophils from lines A and B were isolated from 1-day-old chickens and total phosphorylated PTK and p38, JNK, ERK, and transcription factor (activator protein 1 (AP-1) and nuclear factor kappa B (NF- Kappa B)) protein levels quantified following interaction with Salmonella Enteritidis (SE). Control and SE-treated heterophils from line A had greater (P less than or equal to 0.05) PTK phosphorylation compared to line B with increased (P less than or equal to 0.05) activation of p38. Conversely, line B heterophils activated JNK (P less than or equal to 0.05). There were no differences in ERK between control and activated heterophils for either line. Defined signalling inhibitors were used to show specificity. The AP-1 and NF- Kappa B transcription factor families were also examined, and c-Jun and p50, respectively, were the only members different between the lines and both were up-regulated in line A compared with line B. These data indicate that increased responsiveness of line A heterophils is mediated, largely, by an increased ability to activate PTKs, the p38 MAPK pathway and specific transcription factors, all of which directly affect the innate immune response.

Plantings of temperate bamboo (Poaceae), including species native to West Virginia, were established to determine the potential nutritive value for small ruminants, such as goats (Capra hircus), at different times of the year. The bamboo species we evaluated, included several Phyllostachys spp., Semiarundiaria fastuosa and Arundinaria gigantea, were able to withstand Appalachian winter temperatures and retain some green leaves even in late winter. Although small differences were evident, the nutritive value was generally comparable among species and exhibited similar trends over the season. Total non-structural carbohydrates in bamboo leaves decreased throughout the growing season, and then remained stable or increased during winter. Conversely, crude protein was relatively low in young leaves compared to late season or over-wintered leaves. Concentrations of fiber and protein were sufficient to meet the maintenance needs of adult goats. The ability of bamboo to remain green and maintain the nutritive value throughout winter suggested that it has potential as winter forage for goats in central Appalachia. As an upright browse, bamboo may reduce the exposure of goats to gastrointestinal parasites. Perennial stands of temperate bamboo could prove to be a valuable, multiple-use crop suitable for Appalachian farm operations and easily adaptable to goat production systems.

To evaluate the effect of temperature, genotype, and exogenous calcium application on fertilization and pistil biochemistry in cotton, thermosensitive (cv. ST4554 B2RF) and thermotolerant (cv. VH260) plants were grown under control (30/20 degree C) or high-temperature (38/20 degree C) conditions during flowering, and exogenous CaCl2 was applied to flowers 1day prior to anthesis. Measured pistil parameters included fertilization efficiency; protein concentration; glutathione reductase, superoxide dismutase (SOD) and NADPH oxidase activities; and ATP and calcium levels. Exogenous calcium had no effect on reproductive thermostability due to poor calcium uptake under high temperature. High temperature resulted in a 19.2% decline in fertilization efficiency for ST4554 but no change in fertilization efficiency for VH260 relative to optimal temperature conditions. Pre-stress glutathione reductase and SOD activities were higher in VH260 than ST4554 pistils, and calcium and ATP content were higher in VH260 than ST4554 pistils. It was concluded that pre-stress antioxidant enzyme activity, ATP and calcium content of the pistil may be associated with reproductive thermotolerance in cotton. These findings should be confirmed in future experiments with a larger number of cultivars.

To decipher the key factors controlling carotenoid levels in tubers, four potato lines (Atlantic, Desiree, 91E22 and POR03) were examined by a combination of biochemical, molecular and genomics approaches. These lines contained incremental levels of carotenoids, which were found to be associated with enhanced capacity of carotenoid biosynthesis as evident from norflurazon treatment. Microarray analysis of high and low carotenoid lines (POR03 versus Atlantic) revealed 381 genes that showed significantly differential expression. The carotenoid metabolic pathway genes beta -carotene hydroxylase 2 (BCH2) and beta -carotene hydroxylase 1 (BCH1), along with zeaxanthin epoxidase (ZEP), and carotenoid cleavage dioxygenase 1A (CCD1A) were among the most highly differentially expressed genes. The transcript levels of BCH2 and BCH1 were lowest in Atlantic and highest in POR03, whereas those of ZEP and CCD1A were high in low carotenoid lines and low in high carotenoid lines. The high expression of BCH2 in POR03 line was associated with enhanced response to sugars. Our results indicate that high levels of carotenoid accumulation in potato tubers were due to an increased metabolic flux into carotenoid biosynthetic pathway, as well as the differential expression of carotenoid metabolic genes.

Because of the existing agricultural land-use and future likelihood of urbanization, two losing-stream karst basins were chosen for intensive monitoring in Boone County, Missouri: Hunters Cave and Devils Icebox. Both caves were formed in Burlington Limestone and have similar recharge areas (33 to 34 km super(2)) and land uses. Year-round monitoring was conducted from April 1999 through March 2002 to characterize the water quality of the main cave streams relative to herbicide, nutrient, and sediment contamination. Water sampling entailed grab samples at regular intervals and runoff-event samples collected using automated sampling equipment. Total nitrogen, phosphorus, and sediment concentrations and loads were consistently higher in the Devils Icebox stream compared to Hunters Cave. Median total N fluxes were 96 g km super(-2) d super(-1) at Devils Icebox and 30 g km super(-2) d super(-1) at Hunters Cave, while median total P fluxes were 8.5 g km super(-2) d super(-1) at Devils Icebox and 3.3 g km super(-2) d super(-1) at Hunters Cave. Herbicides or their metabolites were detected in more than 80% of the samples from both cave streams, and herbicide concentrations and areal loss rates were generally similar between the sites. Overall, the greater loads and mass flux of contaminants in the Devils Icebox recharge area compared to Hunters Cave was a result of both greater stream discharge and the occurrence of more cropped fields (94%) on claypan soils with high runoff potential. These claypan soils are known to be especially problematic with respect to surface transport of contaminants. Prevailing land use has significantly degraded the water quality in both recharge areas, but a watershed plan has been developed for the Bonne Femme watershed, which encompasses these two recharge areas. With the baseline data collected in this study, the impact of changing land uses and the implementation of management practices or new ordinances designed to improve water quality can be documented.

By the 1950s, 2-3 million cattle were being vaccinated annually with the strain 19 vaccine, but because this vaccine induced strong, long-term titers on agglutination tests that interfered with identification of cattle infected with field strains of B. abortus, its use in cattle was discontinued in 1970. Soviet scientists then began a comprehensive program of research to identify vaccines with high immunogenicity, weak responses on agglutination tests and low pathogenicity in humans, as a foundation for widespread control of cattle brucellosis. While several new vaccines that induced weak or no responses on serologic agglutination tests were identified by experiments in guinea pigs and cattle, a large body of experimental and field studies suggested that the smooth-rough strain SR82 vaccine combined the desired weak agglutination test responses with comparatively higher efficacy against brucellosis. In 1974, prior to widespread use of strain SR82 vaccine, over 5300 cattle farms across the Russian Federation were known to be infected with B. abortus. By January 2008, only 68 cattle farms in 18 regions were known to be infected with B. abortus, and strain SR82 continues to be the most widely and successfully used vaccine in many regions of the Russian Federation.

Feral swine damage to property, crops, and livestock exceeds $50 million annually. These figures do not include the increased risks and costs associated with the potential for feral swine to spread disease to domestic livestock. Thus, effective bio-security measures will be needed to quickly isolate affected feral swine populations during disease outbreaks. We evaluated enclosures built of 0.86-m-tall traditional hog panels for containing feral swine during 35 trials, each involving 6 recently caught animals exposed to increasing levels of motivation. During trials, fences were 97% successful when enclosures were entered by humans for maintenance purposes; 83% effective when pursued by walking humans discharging paintball projectors; and in limited testing, 100% successful when pursued and removed by gunners in a helicopter. In addition to being effective in containing feral swine, enclosures constructed of hog panels required simple hand tools, took <5 min/m to erect, and were inexpensive ($5.73/m excluding labor) relative to other fencing options. As such, hog-panel fences are suitable for use by state and federal agencies for rapid deployment in disease response situations, but also exhibit utility for general control of other types of damage associated with feral swine.

Latin type cultivars are a potential useful source of resistance to Sclerotinia minor for breeding resistant romaine cultivars. However, resistance in Latin cultivars may be conditioned by their relatively short stature. The objective of this research was to determine the segregation for plant height and the relationship between plant height and S. minor resistance in romaineLatin crosses. The frequency of short plants was conditioned by a single recessive gene in F1, F2 and F3 families from nine romaineLatin crosses tested in 2007, 2008 and 2009 field experiments. The gene, named short leaf 1 (sl1), affects only leaf length in rosette plants and is morphologically distinct from other dwarfing genes. In two S. minor-infested field experiments with 75F3 romaine'Eruption' families, no difference in disease incidence was detected between short (sl1sl1), tall (Sl1Sl1) or segregating families. Therefore, development of resistant romaine cultivars from crosses with 'Eruption' is feasible.

Mosquito responses were compared on a catch-per-unit-effort basis using regression analysis with LT and HL as the dependent and independent variables, respectively. The average number of mosquitoes captured in 1min by LT over a 24-h period was significantly related to the average number captured in 1min by HL only for Cx. nigripalpus and Cx. quinquefasciatus. Patterns of diel activity indicated by a comparison of the mean response to LT and HL at eight different times in a 24-h period were not superposable for any species. The capture rate efficiency of LT when compared with HL was less than or equal to 15% for all mosquitoes except Cx. quinquefasciatus (43%). Statistical models of the relationship between mosquito responses to each collection method indicate that, except for Ae. albopictus, LT and HL capture rates are significantly related only during certain times of the diel period. Estimates of mosquito activity based on observations made between sunset and sunrise were most precise in this regard for An. quadrimaculatus and Cx. nigripalpus, as were those between sunrise and sunset for Cx. quinquefasciatus and Ae. triseriatus.

S.T. Blake (Myrtales: Myrtaceae) forms dense monocultures that displace native vegetation in wetlands of southern Florida, USA. Faunal studies in the tree's native Australian range revealed several prospective biological control agents, including the leaf-blotching bug, Eucerocoris suspectus Distant (Hemiptera: Miridae). This herbivore was imported into quarantine to assess risk to Florida native and ornamental species after preliminary Australian studies had indicated that it might be useful. Ornamental Melaleuca spp. suffered heavy feeding in no-choice adult feeding trials, with moderate feeding on some native Myrtaceae. Native species sustained light to heavy feeding in multichoice adult feeding trials and in a no-choice nymphal feeding trial. Feeding increased on native species in a large enclosure after M. quinquenervia was cut, allowed to dry, and then removed. Nymphs completed development only on M. quinquenervia and ornamental bottlebrushes, Melaleuca spp. However, inability to fully develop on non-target species is of limited importance as a criterion for release of insects with highly mobile immature stages as compared to less vagile species. Local movement from the host to other plant species could result in unacceptable non-target damage despite seemingly adequate developmental specificity. This insect would clearly harm native and ornamental Myrtaceae and should therefore not be released.

Contributions of male bees to host pollination are rarely studied directly despite their prevalence in a number of pollination guilds, including those of some crop plants. In this study, males of the oligolectic bee, Peponapis pruinosa Say, were shown to be effective pollinators of summer squash, Cucurbita pepo L. Seven sequential visits from male P. pruinosa maximized squash fruit set and growth. This number of male visits accumulated during the first hour of their foraging and mate searching at flowers soon after sunrise. Pollination efficacy of male P. pruinosa and their abundances at squash flowers were sufficient to account for most summer squash production at our study sites, and by extrapolation, to two-thirds of all 87 North American farms and market gardens growing squashes that were surveyed for pollinators by collaborators in the Squash Pollinators of the Americas Survey. We posit that the substantial pollination value of male Peponapis bees is a consequence of their species' oligolecty, their mate seeking strategy, and some extreme traits of Cucurbita flowers (massive rewards, flower size, phenology).

No Hessian fly puparia (45,366) survived to the adult stage in infested wheat, Triticum aestivum L., seedlings exposed to the treatment in a large-scale commercial test. Daily temperatures (mean plus or minus SEM) inside and among bales in three test freight containers were 17.8 plus or minus 0.2 front top, 17.0 plus or minus 0.2 front bottom, 17.3 plus or minus 0.2 middle bale, 15.7 plus or minus 0.3 middle air, 18.5 plus or minus 0.1 back top, and 18.1 plus or minus 0.1 degree C back bottom, allowing the fumigation temperature to be established at greater than or equal to 20 degree C. Mean fumigant concentrations ranged from 208 to 340 ppm during the first 3 d and ranged from 328 to 461 ppm after 7 d of fumigation. Copper plate corrosion values inside the doors, and in the middle of the large-size bales in all locations indicated moderate exposure to hydrogen phosphide (PH3). PH3 residues were below the U.S. Environmental Protection Agency tolerance of 0.1 ppm in animal feeds. The research was approved by Japan and U.S. regulatory agencies, and regulations were implemented on 20 May 2005. Compression in large-size bale compressors resulted in 3-3.6 and 0% survival of Hessian fly puparia and cereal leaf beetle, Oulema melanopus (L.), respectively.

The biology and larval and adult host range of this species were examined to determine the insect's suitability for biological control of this invasive weed in North America and Hawaii. Biological observations indicate that the larvae have five instars. When disturbed, the late instar larvae emit formic acid from a prothoracic gland that may protect larvae from generalist predators. Larval host range tests conducted both in South and North America indicated that this species feeds and completes development primarily on members of the Anacardiaceae within the tribe Rhoeae. Oviposition tests indicated that when given a choice in large cages the adults will select the target weed over Pistacia spp. However, considering the many valued plant species in its host range, especially several North American natives, this species will not be considered further for biological control of S. terebinthifolius in North America.

A previous study found that the current use of 2--4 traps per 64 ha block usually is not sufficient to provide management information specifically for that block. In this study, we compare data from large grids of egg traps in varied commercial almond orchards with trapping data for females and males, with the objective of finding a more cost-effective monitoring program using currently available attractants. The proportion of egg traps with eggs was highly correlated with mean eggs per egg trap, and with females and males trapped simultaneously at the same location. Almond variety and the type of bait used had little impact on the relationship between the proportion of egg traps with eggs and the number of eggs per traps. Traps in orchards with more unharvested (mummy) almonds had more eggs, suggesting that navel orangeworm abundance affected traps more than competition from mummies. Laboratory experiments comparing age-specific oviposition in two-choice and no-choice situations found that younger, more fecund females laid a greater proportion of eggs on the preferred substrate in a two-choice situation, but that age-specific fecundity was not different between substrates in no-choice tests. These findings indicate that the proportion of egg traps with eggs provides a more stable indication of navel orangeworm phenology than mean eggs per trap. We suggest that similar information could be obtained in a more cost-effective manner with female trapping.

However, compounds produced by the larvae themselves have not been previously described nor their significance to parasitoid foraging determined. We collected the volatiles from four species of tropical and subtropical Tephritidae: Anastrepha suspensa (Loew), Bactrocera dorsalis Hendel, Bactrocera cucurbitae Coquillett, and Ceratitis capitata (Wiedemann), representing two subfamilies (Dacinae and Trypetinae). Paraethylacetophenone, an analog of a known tephritid parasitoid attractant, was a major constituent of all four, and was not associated with larvae of another acalypterate fly, Drosophila melanogaster Meigen, or with the calypterate Musca domestica L. It also was present in volatiles from whole, A. suspensa infested fruits of Eugenia uniflora (L.). Para-ethylacetophenone was not necessarily produced as a direct consequence of fruit consumption because it also was detected from larvae that developed in two artificial diets and in spent diets subsequent to larval development. Sensillae on both the antennae and ovipositor of the opiine braconid fruit fly parasitoid, Diachasmimorpha longicaudata (Ashmead) responded to the para-ethylacetophenone in larval volatiles and as a synthetic. Although a potential cue to foraging parasitoids, para-ethylacetophenone showed no long range (>1m) attractiveness to the adult female parasitoid, but did stimulate ovipositor-insertion and oviposition into both a natural (fruit) and an artificial (parafilm) substrate. Thus it may prove useful in colonizing and mass-rearing opine fruit fly parasitoids.

Five years later, this fly is firmly established at the original release site and has expanded outward at least 18 km. Nevertheless, populations remain very low considering P. litoralis is one of the most abundant fire ant decapitating flies in large areas of its range in South America. The reasons for low densities and why we were only able to establish this fly at 1 of 9 release sites in 4 states (2003-2006) are unknown, but problems with host-matching, release procedures, weather conditions, and competition with previously released decapitating flies are discussed as possible factors.

E. Smith), to the single Bacillus thuringiensis (Bt) cotton trait, Bollgard registered and dual Bt cotton traits (Bollgard II registered and WideStrike(TM)(TM)) by using a cotton leaf-tissue assay and by incorporating lyophilized cotton tissue into a meridic diet. Bioassays were conducted for both neonate and 3rd instars. Leaf tissue bioassays indicated that Bollgard II registered and WideStrike(TM) are highly effective against fall armyworm neonates by causing mortality and by retarding development parameters such as larval weight, pupal duration, and time to adulthood. Bollgard registered was not significantly different from non-transgenic cotton in terms of mortality or feeding, with the exception of the non--Bt (PhytoGen 425RF), which had an inherent form of resistance that is not associated with a transgenic event. Third instars evaluated with lyophilized diet bioassays were not as affected by the Bt traits to the same degree as neonates; however, larval weights were lower, and developmental parameters such as time to pupation and time to adulthood were longer. The duration of pupal development was significantly longer for 3rd instars that survived the highest dose of 5,000 mu g of WideStrike(TM) cotton tissue. Sublethal doses for Bollgard II registered and WideStrike(TM) were generally observed at 500 to 5,000 mu g of lyophilized cotton tissue per mg of meridic diet, depending upon the variable (time to pupation, pupal duration, time to adult emergence) measured.

A wetland consisting of a sediment trap and two treatment cells was constructed in a Mississippi Delta lake watershed. A 3-h simulated runoff event was initiated (2003) to evaluate fate and transport of atrazine and fluometuron through the wetland. Water samples were collected during a runoff simulation and then afterward at selected intervals for 21d, and analyzed for the herbicides. Breakthrough patterns for herbicide concentrations in water samples during the first 20h after simulated runoff showed peak concentrations in the first 6h, with gradual tailing as the herbicide pulse was diluted in the second, excavated (deeper) cell. Atrazine and fluometuron concentrations in the first (shallower, non-excavated) cell averaged 12- and 20-fold greater, respectively, than those in the second cell following simulated runoff, indicating entrapment in the first cell. Atrazine and fluometuron concentrations in the shallower cell decreased 32% and 22%, respectively, 9d following simulated runoff, indicating either degradation or sorption to soil or wetland flora. In the excavated cell, concentrations were even lower, and atrazine declined more rapidly than fluometuron.

Phage whole-genome tetra-nucleotide signatures and proteomic tree topologies correlated closely with host phylogeny. Comparisons of our phage genomes to 26 others revealed three shared COGs; of particular interest within this core genome was an endolysin (PF01520, an N-acetylmuramoyl-L-alanine amidase) and a holin (PF04531). Comparative analyses of the evolutionary history and genomic context of these common phage proteins revealed two important results: 1) strongly significant host-specific sequence variation within the endolysin, and 2) a protein domain architecture apparently unique to our phage genomes in which the endolysin is located upstream of its associated holin. Endolysin sequences from our phages were one of two very distinct genotypes distinguished by variability within the putative enzymatically-active domain. The shared or core genome was comprised of genes with multiple sequence types belonging to five pfam families, and genes belonging to 12 pfam families, including the holin genes, which were nearly identical. Significant genomic diversity exists even among closely-related bacteriophages. Holins and endolysins represent conserved functions across divergent phage genomes and, as we demonstrate here, endolysins can have significant variability and host-specificity even among closely-related genomes. Endolysins in our phage genomes may be subject to different selective pressures than the rest of the genome. These findings may have important implications for potential biotechnological applications of phage gene products.

Total coccinellid densities were 50-77% greater in sugar-sprayed soybean than in untreated plots. Coccinella septempuncata L., Hippodamia convergens Guerin-Meneville, and Harmonia axyridis Pallas were more abundant where sugar was applied. Coleomegilla maculata (DeGeer) was found in equally low numbers in all treatments. Aphid densities were similar in both treatments, and only reached economically threatening levels in SD. Coccinellids digested sugar meals within 1 h of consumption (measured using the cold anthrone test). Despite this narrow window of detection, field-collected coccinellids frequently tested positive for fructose. Under natural conditions, sugar is commonly ingested by coccinellids and sugar sprays increase coccinellid densities and their consumption of sugar. Sugar sprays did not enhance biological control of aphids in this experiment.

Watson, are encountering increased abiotic stress and pest activity due to recent increases in temperature and changes in precipitation throughout their range. This tree species counters these threats by producing secondary metabolites, including phenolics and terpenoids. We examined foliar levels of lignin, soluble phenolics, monoterpenoids, sesquiterpenoids, and diterpenoids in 12 stands in British Columbia, Canada. We used these data to assess associations among foliar secondary metabolite levels and ecosystem, geographic, and climatic variables. Regressions were also performed to observe which combinations of variables best explained secondary metabolite variance. Stands of P. c. latifolia in the Coastal Western Hemlock and Interior Cedar/Hemlock biogeoclimatic zones had consistently greater foliar levels of almost all measured secondary metabolites than did other stands. Lignin was present in greater amounts in Boreal White/Black Spruce ecosystem (i.e., northern) stands than in southern stands, suggesting a role for this metabolite in pine survival in the boreal forest. Attempts to develop regression models with geographic and climatic variables to explain foliar secondary metabolite levels resulted in multiple models with similar predictive capability. Since foliar secondary metabolite levels appeared to vary most between stand ecosystem types and not as much due to geographic and climatic variables, metabolic profiles appeared best matched to the stress levels within local environments. It is unknown if differences in secondary metabolite levels are the result of genetic adaptation or phenotypic plasticity, but results from this and other studies suggest that both are important. These results are interpreted in light of ongoing efforts to assist in the migration of certain populations of P. c. latifolia northward in an effort to counter predicted effects of climate change.

However, estimates of the potential increases in forest carbon, sequestration as a result of increased stocking levels are not readily available. Using the USDA Forest Service's Forest Inventory and Analysis data coupled with the Forest Vegetation Simulator, we estimate that, for a seven-state region in the northeastern United States, timberland contains about 1768 Tg of carbon in aboveground live biomass across all stocking classes. If all medium and understocked stands had the carbon density of fully stocked stands, an additional 453 Tg of carbon would be stored. While the carbon gains per unit area are greatest for understocked stands, generally fewer than 10% of stands are in this condition. The increase in carbon storage per unit area is smaller for stands in the medium stocked class, but the large proportion of stands in this condition offers considerable opportunities. Our analysis indicates that, when seeking to increase forest carbon storage, managing stocking levels is an option with considerable potential, especially since no changes in land use are required.

We first describe new developments in wildfire simulation technology that catalyzed the development of risk-based decision support systems for strategic wildfire management. These systems include new analytical methods to measure wildfire risk to human and ecological values and to inform fuel treatment investment strategies at national, regional, and local scales. Application of the risk management framework to support wildfire incidents has been dramatically advanced with the Wildland Fire Decision Support System and allowed policy modifications that encourage management of incidents for multiple objectives. The new wildfire risk management decision support systems we discuss provide Federal agencies in the US the ability to integrate risk-informed approaches to a wide range of wildfire management responsibilities and decisions. While much progress has been made, there remain several barriers that need to be addressed to fully integrate risk science into current wildfire management practices. We conclude by identifying five primary issues that if properly addressed could help public land management better realize the opportunities and potential payoffs from fully adopting a risk management paradigm.

We describe the morphological and physiological responses of coast live oak, Quercus agrifolia NACOe, in California to an invasive insect, the goldspotted oak borer (GSOB), Agrilus auroguttatus Schaeffer (Coleoptera: Buprestidae), and evaluate drought as a potential inciting factor. Morphological traits of 356 trees were assessed and physiological traits of 70 of these were monitored intensively over one growing season. Morphological characteristics of tree health included crown thinning and dieback; bole staining resulting from larval feeding; density of GSOB adult exit holes; and holes caused by woodpecker feeding. These characteristics were used to rank GSOB infestation/injury into four classes, and taken together, they explained 87% of the variation in a principal component analysis. Drought stress on various size/age and infestation classes of Q. agrifolia was measured by assessing branchlet pre-dawn and solar noon xylem water potential, leaf cell turgor potential, and water use efficiency over one growing season. Both morphological and physiological traits were highly variable in mature and old growth trees. Early summer plant water status (branchlet xylem water potential and water use efficiency) was similar between uninfested and newly colonized trees, suggesting that GSOB are not pre-selecting drought-stressed Q. agrifolia for oviposition. By late summer, leaf water and cell turgor potentials were lower in infested than in uninfested mature trees, suggesting that GSOB infestation causes drought stress in these trees. Among the tree size/age classes, infested old growth trees exhibited the greatest change in water use efficiency over the growing season, and showed greater morphological injury symptoms of decline than infested mature trees. Morphological attributes of decline in Q. agrifolia associated with GSOB were correlated weakly with increasing physiological drought stress among infestation classes of trees. We propose that the collection of morphological responses of Q. agrifolia to GSOB described here can be used to monitor the future expansion of the GSOB distribution as well as the GSOB-induced decline of Q. agrifolia in California.

Larvae of a small moth, Austromusotima camptozonale, were discovered defoliating L. microphyllum in Australia. Preliminary testing suggested this moth was a Lygodium specialist. Laboratory host range testing was conducted on 65 species of test plants, from 31 families, comprising seven Lygodium species, four close relatives, 45 other species of ferns and fern allies, eight agricultural crops and one gymnosperm species plus the primary host L. microphyllum. Significant oviposition occurred only on other species of Lygodium. No eggs were laid on the agricultural crops, or about half the species of non-Lygodium ferns and fern allies tested. Oviposition on the other non-Lygodium ferns was very low, except on Anemia adiantifolia and Blechnum serrulatum, which received modest egg loads, but did not support development to adult. Larval feeding was low to non-existent on all the non-Lygodium species. Larvae developed to adult only on the native, American climbing fern L. palmatum, and to a lesser extent on L. japonicum. Lygodium japonicum is a naturalized invasive weed in the United States. Colonies of A. camptozonale were unable to persist on L. palmatum and died out in two to seven generations. Freezing winter temperatures in states where L. palmatum occurs would be lethal to A. camptozonale. It was concluded that A. camptozonale would pose no threat to native or cultivated plants in North America or the Caribbean and should be considered as a weed biological control agent against L. microphyllum.

Increased CO sub(2) also may alter element levels in biomass from multi-species vegetation by changing plant species abundances. We measured concentrations of ten elements in aboveground tissues of three C sub(4) grasses that had been exposed for 2-3 growing seasons to a continuous gradient in CO sub(2) from 250 to 500 mu molmol super(-1). The grasses, Bouteloua curtipendula, Schizachyrium scoparium, and Sorghastrum nutans, are competitive dominants in assemblages of tallgrass prairie vegetation growing on each of three soil types along a field CO sub(2) gradient in central Texas, USA. Our objective was to determine whether CO sub(2) influences element concentrations in grass mixtures by changing concentrations in individual species or shifting species abundances. Increased CO sub(2) had little effect on element concentrations in grasses compared to differences observed among grass species and soils. Increasing CO sub(2) from the pre-Industrial to elevated levels reduced the phosphorus concentration in grasses grown on a clay and sandy loam soil. Concentrations of most other elements did not respond to CO sub(2) treatment. Cover of the mid-grass Bouteloua declined at higher CO sub(2) levels as cover of the taller grass Sorghastrum increased. Concentrations of several elements were lower in Bouteloua than Sorghastrum; hence, this exchange of species at higher CO sub(2) increased element concentrations in grass assemblages. Potential consequences include an improvement in the nutritional quality of plants for herbivores. Results highlight the underappreciated impact that CO sub(2) enrichment may have on ecosystem functioning by changing plant composition.

In August 2000, wildfire burned portions of the Little Granite Creek watershed near Bondurant, WY where bedload and suspended sediment measurements had been collected during 13 previous runoff seasons. This presented an opportunity to quantify increases in sediment loads associated with a large-scale natural disturbance. The first three years post-fire were warm and dry, with low snowpacks and few significant summer storms. Despite relatively low flows during the first runoff season, the estimated sediment load was about five times that predicted from regression of data from the pre-burn record. Increased sediment loading occurred during the rising limb and peak of snowmelt (54%) and during the few summer storms (44%). While high during the first post-fire year, total annual sediment yield decreased during the next two years, indicating an eventual return to baseline levels. The results from this sediment monitoring lacked some of the more dramatic responses that have been observed in other watersheds following fire. In other environments, moderate-to-high intensity rainstorms caused significant flooding, widespread debris flows and channel incision and aggradation. A few moderate intensity storms (<2year recurrence interval) occurred in the Little Granite Creek watershed, but they did not trigger this type of response. Instead, ash and charcoal rich discharges (herein described as ablackwater flowsa) and heavily sediment laden flows were observed without physical evidence of debris flows, as defined by channel incision into previously unchanneled areas. Speculatively, the sedimentation pattern and geomorphic response in Little Granite Creek may be fairly typical of stream responses to wildfire during times of continued drought and in the absence of widespread, significant rainfall, representing one type of response on a continuum of effects following wildfire.

Rapid spectroscopic methods increase measurement density of soil nutrients and improve the accuracy of rates of additional P inputs. Materials and methods: Soil P was measured by a multi-element energy-dispersive X-ray fluorescence spectroscopic (XRFS) method to estimate the spatial distribution of soil total (XRFS-P) and bioavailable P in a Fluvisol occurring on a 20-ha contiguous area comprised of seven elongated field strips under a wheat-maize rotation near the Quzhou Agricultural Experiment Station in the North China Plain. Results and discussion: Soil XRFS-P was highly variable along the length of the field strips and across the entire area after decades of continuous cultivation. A linear relationship existed between XRFS-P and bicarbonate-extractable P or Mehlich 3-extractable P, allowing a description of the spatial distribution of bioavailable P based on XRFS, in both directions of a two-dimensional grid covering the entire area (p<0.05). Distinct management zones were identified for more precise placement of additional P. Conclusions: Direct element-specific analysis and a high sample throughput make XRFS an indispensable component of a new approach to sustainably manage P, and other macronutrients of low atomic number Z such as K, Ca, or Cl in production fields, based on their site-specific variations in the soil. Concerning P, this rapid precision approach provides a promising avenue to manage soil P as a regionalized variable while preventing zones of deficiency or surplus P that can affect plant productivity or potential loss from a field, respectively.

Most oil producers fell into phylogenetic clades 8, 9, and 11. Oil colors ranged from bright yellow to malachite. More than half of the strains produced oil that was fluorescent. In medium containing 5% (w/v) sucrose, oil yields ranged from 0.5 to 6g oil/l. Strain CU 43 reached stationary growth phase at day 4 while oil yields were maximal at day 6. CU 43 produced bright yellow, highly fluorescent oil that also was visible as intracellular droplets under fluorescent microscopy. Oil was surface active, suggesting that it functions as a biosurfactant. Oil from two strains (CU 43 and NRRL Y-12974) differentially inhibited mammalian cancer cell lines. MALDI-TOF MS spectra suggested that A. pullulans strains produce a family of related oil structures.

Purified Leuconostoc mesenteroides exopolysaccharide (EPS) coatings, cast from aqueous solution, inhibited the corrosion of low-carbon steel as determined by electrochemical impedance spectroscopy (EIS). There were two different corrosion behaviors exhibited when EPS films from different strains were cast onto the steel. One EPS coating reacted immediately with the steel substrate to form an iron (III) oxide layer ("rust") during the drying process while another did not. The samples that did not flash corrode had higher corrosion inhibition and formed an iron (II) passivation layer during EIS testing that persisted after the cells were disassembled. Corrosion inhibition was strain-specific as polysaccharides with similar structure did not have the same corrosion potential.

Overall, a dietary level of 3.0gl-1 gave the shortest developmental times over two generations. The likelihood of egg hatch at one ascorbic acid concentration compared to another concentration suggested that egg hatch increased as the concentration of ascorbic acid increased from 0.07 to 3.0gl-1 and then declined from 3.0 to 30.0gl-1. The combination of the maximum egg oviposition at 0.3 and 3.0gl-1, egg hatch at 3.0gl-1, and survival at 0.07 and 0.3gl-1 suggests an overall superior performance at a concentration between 0.3 and 3.0gl-1. Depletion of ascorbic acid below 3.0gl-1 or addition of ascorbic acid above 3.0gl-1 lowered the likelihood of egg hatch, which became more pronounced in the second generation. This is consistent with previously published information for phytophagous insects.

AN - 876226013; 14889253 AB - 1.State-and-transition models (STMs) synthesize and communicate knowledge about the alternative states of an ecosystem and causes of state transitions. Data supported narrative descriptions within STMs are used to select or justify management actions. State transitions are characteristically heterogeneous in space and time, but spatial heterogeneity is seldom described in STMs, thereby limiting their utility. 2.We conducted a review that indicates how spatially explicit data can be used to improve STMs. We first identified three spatial scales at which spatial patterns and processes are manifest: patches, sites and landscapes. We then identified three classes of spatial processes that govern heterogeneity in state transitions at each scale and that can be considered in empirical studies, STM narratives and management interpretations. 3.First, spatial variations in land-use driver history (e.g. grazing use) can explain differences in the occurrence of state transitions within land areas that are otherwise uniform. Secondly, spatial dependence in response to drivers imposed by variations in soils, landforms and climate can explain how the likelihood of state transition varies along relatively static environmental gradients. Thirdly, state transition processes can be contagious, under control of vegetation-environment feedbacks, such that the spatiotemporal evolution of state transitions is predictable. 4.We suggest a strategy for considering each of the three spatial processes in the development of STM narratives. We illustrate how spatial data can be employed for describing early warning indicators of state transition, identifying areas that are most susceptible to state transitions, and designing and implementing monitoring schemes. 5.Synthesis and applications. State-and-transition models are increasingly important tools for guiding land-management activities. However, failure to adequately represent spatial processes in STMs can limit their ability to identify the initiation, risk and causes of state transitions and, therefore, the appropriate management responses. We suggest that multi-scaled studies targeted to different kinds of ecosystems can be used to uncover evidence of spatial processes. Such evidence should be included in STM narratives and can lead to novel interpretations of land change and improved management.

These physiological effects of ozone forecast changes in evapotranspiration and thus in the terrestrial hydrological cycle, particularly in intercontinental interiors. Soybean plots were fumigated with ozone to achieve concentrations above ambient levels over five growing seasons in open-air field conditions. Mean season increases in ozone concentrations ([O3]) varied between growing seasons from 22 to 37% above background concentrations. The objective of this experiment was to examine the effects of future [O3] on crop ecosystem energy fluxes and water use. Elevated [O3] caused decreases in canopy evapotranspiration resulting in decreased water use by as much as 15% in high ozone years and decreased soil water removal. In addition, ozone treatment resulted in increased sensible heat flux in all years indicative of day-time increase in canopy temperature of up to 0.7 degree C.

Risk assessment is a holistic approach to food safety that consists of four steps: 1) hazard identification; 2) exposure assessment; 3) hazard characterization; and 4) risk characterization. Risk assessments are modeled by mapping the risk pathway as a series of unit operations and associated pathogen events and then using probability distributions and a random sampling method to simulate the rare, random, variable and uncertain nature of pathogen events in the risk pathway. To model pathogen events, a rare event modeling approach is used that links a discrete distribution for incidence of the pathogen event with a continuous distribution for extent of the pathogen event. When applied to risk assessment, rare event modeling leads to the conclusion that the most highly contaminated food at the processing plant does not necessarily pose the highest risk to public health because of differences in post-processing risk factors among distribution channels and consumer populations. Predictive microbiology models for individual pathogen events can be integrated with risk assessment models using the rare event modeling method. JF - Food Microbiology AU - Oscar, T P AD - U. S.

The new mathematical model was derived from the basic observation of bacterial growth that may include lag, exponential, and stationary phases. With this model, the lag phase duration and exponential growth rate of a growth curve were simultaneously determined by nonlinear regression. The new model was validated using Listeria monocytogenes and Escherichia coli O157:H7 in broth or meat. Statistical results suggested that both bias factor (B f) and accuracy factor (A f) of the new model were very close to 1.0. A new BAlehdrA!dek-type rate model and the Ratkowsky square-root model were used to describe the temperature dependence of bacterial growth rate. It was observed that the maximum and minimum temperatures were more accurately estimated by a new BAlehdrA!dek-type rate model. Further, the inverse of square-roots of lag phases was found proportional to temperature, making it possible to estimate the lag phase duration from the growth temperature.

Cooked, uncured product was inoculated with C. perfringens spores and vacuum packaged. For the isothermal experiments, all samples were incubated in a water bath stabilized at selected temperatures between 10 and 51 degree C and sampled periodically. For dynamic experiments, the samples were cooled from 54.4 to 27 degree C and subsequently from 27 to 4 degree C for different time periods, designated as x and y hours, respectively. The growth models used were based on a model developed by Baranyi and Roberts (1994. A dynamic approach to predicting bacterial growth in food. Int. J. Food Micro. 23, 277-294), which incorporates a constant, referred to as the physiological state constant, q 0. The value of this constant captures the cells' history before the cooling begins. To estimate specific growth rates, data from isothermal experiments were used, from which a secondary model was developed, based on a form of Ratkowsky's 4-parameter equation. The estimated growth kinetics associated with pork and chicken were similar, but growth appeared to be slightly greater in beef; for beef, the maximum specific growth rates estimated from the Ratkowsky curve was about 2.7log10 cfu/h, while for the other two species, chicken and pork, the estimate was about 2.2log10 cfu/h. Physiological state constants were estimated by minimizing the mean square error of predictions of the log10 of the relative increase versus the corresponding observed quantities for the dynamic experiments: for beef the estimate was 0.007, while those for pork and chicken the estimates were about 0.014 and 0.011, respectively. For a hypothetical 1.5h cooling from 54 degree C to 27 degree and 5h to 4 degree C, corresponding to USDA-FSIS cooling compliance guidelines, the predicted growth (log10 of the relative increase) for each species was: 1.29 for beef; 1.07 for chicken and 0.95log10 for pork. However, it was noticed that for pork in particular, the model using the derived q 0 had a tendency to over-predict relative growth when the observed amount of relative growth was small, and under-predict the relative growth when the observed amount of relative growth was large. To provide more fail-safe estimate, rather than using the derived value of q 0, a value of 0.04 is recommended for pork.

This fungus is variable in pathogenicity, morphology, host range and symptom production, and is not a well characterized pathogen on sugar beet. From 1998 to 2003, 86 isolates of F. oxysporum and 20 other Fusarium species from sugar beet, along with four F. oxysporum isolates from dry bean and five from spinach, were obtained from diseased plants and characterized for pathogenicity to sugar beet. A group of sugar beet Fusarium isolates from different geographic areas (including nonpathogenic and pathogenic F. oxysporum, F. solani, F. proliferatum and F. avenaceum), F. oxysporum from dry bean and spinach, and Fusarium DNA from Europe were chosen for phylogenetic analysis. Sequence data from - tubulin, EF1 and ITS DNA were used to examine whether Fusarium diversity is related to geographic origin and pathogenicity. Parsimony and Bayesian MCMC analyses of individual and combined datasets revealed no clades based on geographic origin and a single clade consisting exclusively of pathogens. The presence of FOB and nonpathogenic isolates in clades predominately made up of Fusarium species from sugar beet and other hosts indicates that F. oxysporum f. sp. betae is not monophyletic.

Because seedborne infections are the primary sources of inoculum for SMV infections in North America, host-plant resistance to seed transmission can limit the pool of plants that can serve as sources of inoculum. To examine the inheritance of SMV seed transmission in soybean, crosses were made between plant introductions (PIs) with high (PI88799), moderate (PI60279), and low (PI548391) rates of transmission of SMV through seed. In four F sub(2) populations, SMV seed transmission segregated as if conditioned by two or more genes. Consequently, a recombinant inbred line population was derived from a cross between PIs 88799 and 548391 and evaluated for segregation of SMV seed transmission, seed coat mottling, and simple sequence repeat markers. Chromosomal regions on linkage groups C1 and C2 were significantly associated with both transmission of isolate SMV 413 through seed and SMV-induced seed coat mottling, and explained approximately 42.8 and 46.4% of the variability in these two traits, respectively. Chromosomal regions associated with seed transmission and seed coat mottling contained homologues of Arabidopsis genes DCL3 and RDR6, which encode enzymes involved in RNA-mediated transcriptional and posttranscriptional gene silencing.

E. coli isolates (n = 35) from seven different animal sources were selected and tested for susceptibility to 15 antimicrobials; pulsed-field gel electrophoresis was used to determine genetic relationships among the E. coli isolates. Plasmid types based on their incompatibility (Inc) replicon types were determined, and linkage disequilibrium analysis was performed for antimicrobial resistance profiles, replicon types, and animal source. A high degree of genotypic diversity was observed: 34 different pulsed-field gel electrophoresis types among the 35 isolates examined. Twelve different plasmid Inc types were detected, and all isolates carried at least one replicon type. IncF (n = 25; 71.4%) and IncFIB (n = 19; 54.3%) were the most common replicon types identified. Chloramphenicol resistance was significantly linked with four Inc types (A/C, FIIA, F, and Y), and amoxicillin/clavulanic acid was linked with three Inc types (B/O, P and Y). Resistance to any other antimicrobial was linked to two or fewer replicon types. The isolate source was linked with resistance to seven antimicrobials and Incll. We conclude that commensal E. coli from animal sources are highly variable genotypically and are reservoirs of a diverse array of plasmids carrying antimicrobial resistance.

Error in the weather inputs, typically due to forecasting, interpolation, or estimation from off-site sources, may affeel model calculations and management decision recommendations. The extent to which errors in weather inputs affect the quality of the final management outcome depends on a number of aspects of the disease management context, including whether management consists of a single dichotomous decision, or of a multi-decision process extending over the cropping season(s). Decision aids for multi-decision disease management typically are based on simple or complex algorithms of weather data which may be accumulated over several days or weeks. It is difficult to quantify accuracy of multi-decision DSSs due to temporally overlapping disease events, existence of more than one solution to optimizing the outcome, opportunities to take later recourse to modify earlier decisions, and the ongoing, complex decision process in which the DSS is only one component. One approach to assessing importance of weather input errors is to conduct an error analysis in which the DSS outcome from high-quality weather data is compared with that from weather data with various levels of bias and/or variance from the original data. We illustrate this analytical approach for two types of DSS, an infection risk index for hop powdery mildew and a simulation model for grass stem rust. Further exploration of analysis methods is needed to address problems associated with assessing uncertainty in multi-decision DSSs.

Our objectives were to (1) calibrate SCI scores against SOC from published field studies in the Midwest and (2) compare the calibration with a recently derived calibration from the southeastern United States. We found that SOC sequestration (at 25 plus or minus 6 cm [10 plus or minus 2 in] depth) could be reliably related to SCI across a diversity of studies in the region using the regression slope: 4.52 Mg C ha super(-1) SCI super(-1) (2.02 tn ac super(-1) SCI super(-1)), which translated into a rate of 0.35 plus or minus 0.06 Mg C ha super(-1) y super(-1) SCI super(-1) (314 plus or minus 57 lb ac super(-1) yr super(-1) SCI super(-1)), which is the mean plus or minus standard error of 18 slope estimates. Calibration slopes did not vary significantly between the Midwest and southeastern United States, resulting in a combined calibration of 0.29 plus or minus 0.03 Mg C ha super(-1) y super(-1) SCI super(-1) (255 plus or minus 30 lb ac super(-1) yr super(-1) SCI super(-1)), which is the mean plus or minus standard error of 49 slope estimates. The calibration of SCI scores to SOC will allow SCI to become a quantitative tool for natural resource professionals to predict SOC sequestration for farmers wanting to adopt conservation practices.

The identification and spread of variants of race TTKSK with virulence to additional stem rust resistance genes has reminded breeders and pathologists of the danger of deploying major resistance genes alone. In order to protect wheat from this rapidly spreading and adapting pathogen, multiple resistance genes are needed, preferably from improved germplasm. Preliminary screening of over 700 spring wheat breeding lines and cultivars developed at least 20 years ago identified 88 accessions with field resistance to Ug99. We included these resistant accessions in the stem rust screening nursery in Njoro, Kenya for two additional seasons. The accessions were also screened with a bulk of North American isolates of P. graminis f. sp. tritici in the field in St. Paul, MN. In order to further characterize the resistance in these accessions, we obtained seedling phenotypes for 10 races of P. graminis f. sp. tritici, including two races from the race TTKSK complex. This phenotyping led to the identification of accessions with either adult-plant or all-stage resistance to race TTKSK, and often North American races of P. graminis f. sp. tritici as well. These Ug99 resistant accessions can be obtained by breeders and introgressed into current breeding germplasm.

Virus-like symptoms including mosaic, rugosity, and faint chlorotic spots were first observed on leaves of Brugmansia plants in a south Florida nursery in November 2003. Colombian datura virus (CDV) was identified in these initial plants and subsequent Brugmansia and Datura metel (a Brugmansia relative also grown as an ornamental) plants obtained from Florida, Connecticut, Wisconsin, and California. Overall, 77.5% of Brugmansia and two of four D. metel plants tested were infected with CDV. Partial NIb/CP sequences of 28 Brugmansia CDV isolates from this study were compared with all 16 CDV isolates in GenBank and found to share high levels of nucleotide and amino acid identity, with negative selection estimated to be occurring. A single Brugmansia plant was also infected with a recently described to-bamovirus. The low genetic diversity of CDV observed, along with negative selection pressure on NIb/CP, suggests a recent ancestry (<400 years) of the worldwide population of CDV, coinciding with anthropogenic collection and dissemination of Brugmansia plants from their center of origin.

Ten plants were destructively sampled into eight zones by dividing stems into three zones (lengths of 0 to 2, 4 to 6, and 9 to 15 cm above the medium surface), bagged leaves into one leaf litter zone, and the medium into four zones (three horizontal layers: 1 to 3, 3 to 7, and 7 to 10 cm below the medium surface, with the middle layer further divided by removing the central 7.5-cm-diameter core) in December, February, and May. Only the three stem zones were sampled from 10 plants in early and late June and late July. Of 8,940 total isolations, 3,655 fungi with morphological characteristics of a Rhizoctonia sp. were recovered. Percent recovery differed from the eight zones (P < 0.0001) but did not differ between years (P = 0.3950) and sampling times (P = 0.1896). Frequency of recovery of Rhizoctonia spp. was highest from the lower stem and the leaf litter, and decreased with distance from the leaf litter. Recovery from stems over the six sample times was analyzed separately. Percent recovery differed between stem zones (P < 0.0001), sample times (P = 0.0478), and experiment years (P < 0.0001). In both years, mean recovery of Rhizoctonia spp. was higher from the lower stem and decreased with distance to the upper stem layer. From a subsample of 145 isolates, 95.1% were identified as binucleate Rhizoctonia (BNR) anastomosis groups (AGs)-A, -G, -K, -R, -S, and -U (-P), and 2.8 and 2.1% were Rhizoctonia solani AG-2 and an uncultured Laetisaria sp., respectively. Based on frequency analysis, recovery of BNR AGs differed by plant zone (P < 0.0001) but not over sample times (P = 0.4831). The six AGs of BNR are the predominant Rhizoctonia fungi occupying the habitat niches in container-grown azalea, with little change in population frequency and composition from fall to summer; thus, BNR pathogenic and nonpathogenic to azalea have established a mixed Rhizoctonia community on container-grown azalea.

Trees from the mine grew significantly more slowly than trees from natural areas. Both plant populations grew relatively better in their own soil type. Moreover, an AM symbiosis appeared to mediate local plant adaptation. Mine-soil adapted seedlings were more responsive to AM fungal colonization when grown in mine soil whereas the seedlings from natural areas were more responsive to AM fungal colonization when grown in Indiana's native low nutrient clay soil. AM fungal communities originating from the mined area showed significantly greater colonization levels in mine soil than in native soil, suggesting adaptation of AM fungi to mine-soil conditions. These results suggest that reclamation efforts could be improved by starting with plants and AM fungal communities which are already adapted to the target site.

Analysis of air and soil samples provided evidence for the presence of propagules from Fusarium genotypes that may cause grain infections. Soil population estimates of members of the Gibberella fujikuroi species complex, that includes sorghum pathogens and other Fusarium spp., suggested that adequate inoculum for systemic infections was present. Conidia in air samples within two sorghum fields were collected by passive trapping for 2 years. Subsampled Fusarium isolates indicated that numbers of G. fujikuroi increased from anthesis through maturity, which coincides with grain development stages vulnerable to Fusarium spp. Genotyping using translation elongation factor 1- alpha gene sequences revealed that spore trap isolates included members of G. fujikuroi that are sorghum pathogens: Fusarium thapsinum, F. verticillioides, F. proliferatum, and F. andiyazi. Also detected were F. graminearum, F. subglutinans, and several F. incarnatum-F. equiseti species complex haplotypes that colonize sorghum asymptomatically. All commonly found grain colonizers were detected from air samples in this study.

The objective of this study was to determine the physiological mechanisms of orange rust-induced reductions in sugarcane growth and yield by quantifying effects of the disease on leaf SPAD index (an indication of leaf chlorophyll content), net photosynthetic rate, dark respiration, maximum quantum yield of CO sub(2) assimilation, carbon fixation efficiency, and the relationships between these leaf photosynthetic components and rust disease ratings. Plants growing in pots were inoculated with the orange rust pathogen using a leaf whorl inoculation method. A disease rating was assigned using a scale from 0 to 4 with intervals of 0.5. At disease ratings greater than or equal to 2, the rust-infected leaf portion of inoculated plants showed significant reductions in SPAD index, maximum quantum yield, carbon fixation efficiency, stomatal conductance, leaf transpiration rate, and net photosynthetic rate; but the rusted portion of the infected leaves had increased intercellular CO sub(2) concentration and leaf dark respiration rate. Although leaf SPAD index, photosynthetic rate, stomatal conductance, and transpiration rate at the rust-infected portion decreased linearly with increased rust rating, the effect of orange rust on photosynthetic rate was much greater than that on stomatal conductance and transpiration. Unlike earlier reports on other crops, reduction in leaf photosynthesis by orange rust under low light was greater than that under high light conditions. These results help improve the understanding of orange rust etiology and physiological bases of sugarcane yield loss caused by orange rust.

SCR is currently diagnosed through the visual examination of disease symptoms and pathogen morphology, including pigmentation, size, shape, and location of fruiting structures. However, these characteristics are similar to those produced by the common corn rust fungus P. sorghi, confounding accurate visual diagnosis of SCR. Here we report the development of a realtime polymerase chain reaction assay that discriminates between P. polysora and P. sorghi. Sequences of the rDNA internal transcribed spacer region were determined for P. polysora and P. sorghi. 5-Carboxyfluorescein fluorophore-labeled hydrolysis probes that differed at 14 nucleotide positions between the species were developed from these data and used to screen DNA extracted directly from rust-infected corn leaves. Species-specific, reproducible identifications of the pathogens were made from as little as 50 pg of DNA within 30 min, and were reliably performed from both recent collections and herbarium specimens. This assay will be useful for rapid and accurate diagnosis of SCR, and could serve as a tool to monitor the distribution and incidence of the disease in the United States.

The two alfalfa lines compared were a reduced S-lignin transgenic cultivar generated through down regulation of the caffeic acid O-methyltransferase gene and a wild-type control. Both were harvested at two maturities. All the samples had similar carbohydrate contents including a mean composition of 316 g glucan and 497 g total neutral carbohydrates per kg dry biomass, which corresponds to a theoretic ethanol yield of 382 l/ton. Ethanol yields for alfalfa stems pretreated with dilute-acid were significantly impacted by harvest maturity and lignin composition, whereas when pretreated with dilute-ammonia, yield was solely affected by lignin composition. Use of a recombinant xylose-fermenting Saccharomyces strain, for converting the ammonia pretreated alfalfa samples, further increased ethanol yields. Ethanol yields for the xylose-fermenting yeast were 232-278 l/ton and were significantly enhanced for the reduced S lignin cultivars.

Yecora Rojo) grown in an open field in a semiarid desert region of the southwest USA. A temperature free-air controlled enhancement (T-FACE) apparatus utilizing IR heaters maintained canopy air temperature above 3.0m Heated plots of wheat by 1.3 and 2.7 degree C (0.2 and 0.3 degree C below the targeted set-points of Reference plots with dummy heaters) during daytime and nighttime, respectively. Control plots had no apparatus. Every 6 weeks during 2007-2009 wheat was sown under the three warming treatments (i.e., Control, Heated, Reference) in three replicates in a 3 3 Latin square (LSQ) design on six plantings during 4 months (i.e., January, March, September, December), or in a natural temperature variation treatment (i.e., Control) in three replicates in a randomized complete block (RCB) design on nine plantings during 7 months (i.e., January, February, April, June, July, August, October). Soil temperature (Ts) and volumetric soil-water content ([thetas]s) were 1.3 degree C warmer and 14% lower in Heated compared with Reference plots, respectively. Other than a 1% shading effect, no artifacts on gas exchange or water relations were associated with the IR warming apparatus. IR warming increased carbon gain characteristic of an increase in metabolic rates to higher temperature that may have been attributed to the well-watered wheat crop and the supplemental irrigation that minimized plant-to-air water vapor pressure differences between IR-warmed and nonwarmed plots. Nevertheless, seasonal oscillations in the IR warming response on carbon gain occurred. IR warming decreased leaf water status and provided thermal protection during freeze events. IR warming is an effective experimental methodology to investigate the impact of global climate change on agronomic cropping and natural ecosystems to a wide range of natural and artificially imposed air temperatures.

AN - 868999888; 21348575 AB - Control of foodborne Salmonella within the farm-retail continuum is a complex issue since over 2500 serovars of Salmonella exist, the host range of Salmonella spp. varies greatly, and Salmonella is environmentally ubiquitous. To identify Salmonella enterica serovar Typhimurium (Salmonella Typhimurium) genes important for pathogen survival, our research group previously screened a signature-tagged mutagenesis bank in an ex vivo swine stomach content assay. A mutation in the poxA gene, a member of the gene family encoding class-II aminoacyl-tRNA synthetases, decreased survival of Salmonella Typhimurium in the ex vivo swine stomach content assay. In the current study, complementation with a plasmid-encoded poxA gene restored survival of the poxA mutant to the level of the parental, wild-type strain. In vivo analysis of the poxA mutant in the natural porcine host revealed significantly reduced fecal shedding of Salmonella, decreased colonization of the tonsils, and decreased detection of the mutant strain in the cecal contents of the pigs at 7 days postinoculation (p < 0.05). Body temperature (fever) of the pigs inoculated with wild-type Salmonella Typhimurium was significantly higher than that of pigs inoculated with the poxA mutant (p < 0.05). Two-dimensional gel electrophoresis revealed characteristic differences in the protein profile of the poxA mutant relative to the wild-type strain, indicating that deletion of poxA in Salmonella Typhimurium exerts selective effects on translation and/or posttranslational modifications of mRNA species that are necessary for stress survival and colonization of the natural swine host.

AN - 868030149; 21246198 AB - Fusarium verticillioides is both an endophyte and a pathogen of maize and is a health threat in many areas of the world because it can contaminate maize with fumonisins, a toxic secondary metabolite. We identified eight putative chitin synthase (CHS) genes in F. verticillioides genomic sequence, and phylogenetic evidence shows that they group into seven established CHS gene classes. We targeted two CHSs (CHS5 and CHS7) for deletion analysis and found that both are required for normal hyphal growth and maximal disease of maize seedlings and ears. CHS5 and CHS7 encode a putative class V and class VII fungal chitin synthase, respectively; they are located adjacent to each other and are divergently transcribed. Fluorescent microscopy found that both CHS deficient strains produce balloon-shaped hyphae, while growth assays indicated that they were more sensitive to cell wall stressing compounds (e.g., the antifungal compound Nikkomycin Z) than wild type. Pathogenicity assays on maize seedlings and ears indicated that both strains were significantly reduced in their ability to cause disease. Our results demonstrate that both CHS5 and CHS7 are necessary for proper hyphal growth and pathogenicity of F. verticillioides on maize.

Supplemental irrigation, soil amendment and crop rotation can improve potato growth and tuber yield under drought stress conditions, but may also increase potato tuber diseases. The effects of irrigation, soil amendment and crop rotation on the incidence of tuber diseases were quantified from 1994 to 1997 in potato plots. Surface sprinkler irrigation was applied each year, based on tensiometer or moisture block readings deployed in field plots. Black scurf (Rhizoctonia solani), black dot (Colletotricchum coccodes), silver scurf (Helminthosporium solani) and common scab (Streptomyces scabei) diseases were quantified on potato tubers randomly sampled at harvest and kept at storage temperature of 7.2 degree C before visual disease assessment. The incidence of tuber diseases varied among irrigation treatments, crop rotations and soil amendments. The mean incidence of black scurf, silver scurf and black dot ranged from 3-18, 2-33 and 4-7%, in best, un-irrigated and reduced irrigation, respectively. The incidence of back scurf, silver scurf and black dot diseases ranged from 2.4-10, 0.8-21 and 1-31% on potato tubers grown in plots under green manure rotation crop (peas/vetch). Disease incidences on tubers were 1-28, 0-35 and 2-16% for black scurf, silver scurf and black dot, respectively; when potato plants were grown under small-grain rotation. Soil amendments had significant (p<0.05) effects on the incidences of silver scurf disease in 1997 and black dot disease in 1996 and 1997. The interactions of soil amendment with irrigation resulted in significant effects on black scurf incidence in 1994. This research implied that water application may lead to increases in some potato tuber diseases, however; crop rotation and soil amendment may reduce the incidences of selective potato tuber diseases, depending on the type, duration or frequency of supplemental irrigation.

In this process, in addition to beta -glucanases, which are added to reduce the viscosity of the mash, beta -glucosidase is also added to completely hydrolyze the oligomers obtained during the hydrolysis of beta -glucans to glucose. The model allows determination of capital costs, operating costs, and ethanol production cost for a plant producing 40 million gallons of denatured fuel ethanol annually. A sensitivity study was also performed to examine the effects of beta -glucosidase and barley costs on the final ethanol production cost. The results of this study clearly demonstrate the economic benefit of adding beta -glucosidase. Lower ethanol production cost was obtained compared to that obtained without beta -glucosidase addition in all cases except one where highest beta -glucosidase cost allowance and lowest barley cost were used.

There is lack of sufficient information as to the bioavailability of soil heavy metals to plants and human in urban environments. This study examines the relative leachability of Cr, Ni, As, Cd, Zn, and Pb for soils with varying characteristics. The speciation and mobility of these metals can be qualitatively inferred from the leaching experiments. The goal is to use the data to shed some light on their bioavailability to plant and human, as well as the basis for soil remediation. Selective and sequential chemical leaching methods were both used to evaluate the speciation of Cr, Ni, As, Cd, Zn, and Pb in soil samples collected from New York City residential and community gardens. The sequential leaching experiment followed a standard BCR four-step procedure, while selective leaching involved seven different chemical extractants. The results from selective and sequential leaching methods are consistent. In general, very little of the heavy metals were found in the easily soluble or exchangeable fractions. Larger fractions of Cd and Zn can be leached out than other metals. Lead appears predominantly in the organic or carbonate fractions, of which approximately 30-60% is in the easily soluble organic fraction. Most As cannot be leached out by any of the extractants used, but it could have been complicated by the ineffective dissolution of oxides by ammonium hydroxylamine. Ni and Cr were mostly in the residual fractions but some released in the oxidizable fractions. Therefore, the leachability of metals follow the order Cd/Zn>Pb>Ni/Cr. Despite of the controversy and inaccuracy surrounding chemical leaching methods for the speciation of metals, chemical leaching data provide important, general, and easy-to-access information on the mobility of heavy metals in soils, which in turn relates to their potential bioavailability to plant uptake and human health risk. Such data can be used to guide risk assessment of different metals and develop effective remediation strategies.

This study used a portable field wind tunnel to quantify the PM sub(10 emissions from a bare, fine-textured playa surface located in the far northern Chihuahua Desert. The natural, undisturbed crust and its subjection to two levels of animal disturbance (one and ten cow passes) were tested. The wind tunnel generated dust emissions under controlled conditions for firstly an initial blow-off of the surface, followed by two longer runs with sand added to the flow as an abrader material. Dust was measured using a GRIMM particle monitor. For the study playa, no significant differences in PM) sub(1)0 concentration and emission flux were found between the untrampled surface and following a single animal pass. This was the case for both the initial blow-offs and tests on plots under a steady abrader rate. Significantly higher dust loading was only associated with the effect of 10 animal passes. In the blow-offs, the higher PM sub(10 yield after 10 passes reflected the greater availability of easily entrainable fine particles. Under abrasion, the effect of the heaviest trampling increased the emission flux by a third and abrasion efficiency by around 50% more than values on the untrampled surface. This enhanced abrasion efficiency persisted for a 30 min period under abrasion before the positive effect of the disturbance was no longer evident. The findings highlight the role of a threshold of disturbance that determines if supply-limited surfaces will exhibit enhanced wind erosion or not after undergoing perturbation.)

The identification of vector proteins mediating virus transmission is critical to develop sustainable virus management practices and to understand viral strategies for circulative movement in all insect vectors. Previously, we applied 2-D DIGE to an aphid filial generation 2 population to identify proteins correlated with the transmission phenotype that were stably inherited and expressed in the absence of the virus. In the present study, we examined the expression of the DIGE candidates in previously unstudied, field-collected aphid populations. We hypothesized that the expression of proteins involved in virus transmission could be clinically validated in unrelated, virus transmission-competent, field-collected aphid populations. All putative biomarkers were expressed in the field-collected biotypes, and the expression of nine of these aligned with the virus transmission-competent phenotype. The strong conservation of the expression of the biomarkers in multiple field-collected populations facilitates new and testable hypotheses concerning the genetics and biochemistry of virus transmission. Integration of these biomarkers into current aphid-scouting methodologies will enable rational strategies for vector control aimed at judicious use and development of precision pest control methods that reduce plant virus infection.

Attempts at controlling this fungus are currently being done with biocontrol agents such as bacteria, and this includes bacterial endophytes, such as Bacillus mojavensis. In addition to producing fumonisins, which are phytotoxic and mycotoxic, F. verticillioides also produces fusaric acid, which acts both as a phytotoxin and as an antibiotic. The question now is Can B. mojavensis reduce lesion development in maize during the alloinfection process, simulated by internode injection of the fungus? Mutant strains of B. mojavensis that tolerate fusaric acid were used in a growth room study to determine the development of stalk lesions, indicative of maize seedling blight, by co-inoculations with a wild-type strain of F. verticillioides and with non-fusaric acid producing mutants of F. verticillioides. Lesions were measured on 14-day-old maize stalks consisting of treatment groups inoculated with and without mutants and wild-type strains of bacteria and fungi. The results indicate that the fusaric-acid-tolerant B. mojavensis mutant reduced stalk lesions, suggesting an in planta role for this substance as an antibiotic. Further, lesion development occurred in maize infected with F. verticillioides mutants that do not produce fusaric acid, indicating a role for other phytotoxins, such as the fumonisins. Thus, additional pathological components should be examined before strains of B. mojavensis can be identified as being effective as a biocontrol agent, particularly for the control of seedling disease of maize.Original Abstract: Le mais (Zea mays L.) est sujet a l'infection par Fusarium verticillioides a cause des phenomenes d'auto-infection et d'allo-infection, resultant en maladies et en la contamination des grains de mais par les fumonisines, des mycotoxines. Des tentatives de controle de ce champignon a l'aide d'agents de controle biologique comme les bacteries, notamment les endophytes bacteriens tel que Bacillus mojavensis, sont actuellement en cours. Cependant, le champignon produit aussi de l'acide fusarique qui agit tant comme phytotoxine qu'antibiotique, comme les fumonisines qui sont phytotoxiques et mycotoxiques. La question qui se pose maintenant est de savoir si B. mojavensis peut reduire le developpement des lesions lors du processus d'allo-infection chez le mais, simule par l'injection du champignon dans l'entrenoeud du mais. Des souches mutantes de B. mojavensis tolerantes a l'acide fusarique ont ete utilisees dans une etude en chambre de croissance afin de mesurer le developpement de lesions sur la tige du mais, indicatives de la fusariose, a la suite de l'inoculation de la souche sauvage de F. verticillioides et d'un mutant ne produisant pas d'acide fusarique. Les lesions ont ete mesurees sur des tiges de mais de 14 jours chez les groupes inocules ou non avec les souches mutantes ou sauvages de bacteries et de champignons. Les resultats indiquent que la souche mutante de B. mojavensis tolerante a l'acide fusarique reduisait les lesions de la tige, suggerant que cette substance ait agi comme antibiotique in planta. De plus, le developpement des lesions survenait aussi chez le mais infecte par des souches mutantes de F. verticillioides ne produisant pas d'acide fusarique, indiquant que d'autres phytotoxines comme les fumonisines aient joue un role. Ainsi, des composantes pathologiques additionnelles doivent etre examinees avant que des souches de B. mojavensis puissent etre identifiees comme agents de controle biologique efficaces, particulierement pour le controle des maladies des semis de mais.

DESIGN: Data from a prospective, randomized, controlled study of the effect of vitamin E supplementation on RTIs conducted from April 1998 through August 2001 were analyzed. SETTING: Thirty-three LTCFs in the greater Boston area. PARTICIPANTS: Six hundred seventeen subjects aged 65 and older residing in LTCFs. MEASUREMENTS: RTIs, categorized as acute bronchitis, pneumonia, common cold, influenza-like illness, pharyngitis, and sinusitis, were studied for appropriateness of antimicrobial use, type of antibiotics used, and factors associated with their use. For cases in which drug treatment was administered, antibiotic use was rated as appropriate (when an effective drug was used), inappropriate (when a more-effective drug was indicated), or unjustified (when use of any antimicrobial was not indicated). RESULTS: Of 752 documented episodes of RTI, overall treatment was appropriate in 79% of episodes, inappropriate in 2%, and unjustified in 19%. For acute bronchitis, treatment was appropriate in 35% and unjustified in 65% of cases. For pneumonia, treatment was appropriate in 87% of episodes. Of the most commonly used antimicrobials, macrolide use was unjustified in 43% of cases. No statistically significant differences in the patterns of antibiotic use were observed when stratified according to age, sex, race, or comorbid conditions, including diabetes mellitus, dementia, and chronic kidney disease. CONCLUSION: Antimicrobials were unjustifiably used for one-fifth of RTIs and more than two-thirds of cases of acute bronchitis, suggesting a need for programs to improve antibiotic prescribing at LTCFs.

We quantified the effects of antecedent water content (AWC) on runoff (R) and sediment (E) losses from two loamy sands managed under conventional- (CT), strip- (ST), and/or no-till (NT) systems. Two AWC treatments were evaluated: field moist (FM) and pre-wet (PW), created with and without post pesticide application irrigations (12mm of water added with the rainfall simulated over 30min) for incorporation. Treatments (5) evaluated were: CT+FM, CT+PW, ST+FM, ST+PW, and NT+PW. Field plots, each 2-m-3m, were established on each treatment. Each 6-m2 field plot received simulated rainfall at a variable rainfall intensity (I v) pattern for 70min (site 1) or a constant rainfall intensity (I c) pattern for 60min (site 2; I c =50.8mmh-1). Adding 12mm of water as herbicide incorporation increased AWCs of the 0-2 (3-9-fold) and 2-15 (23-117%)cm soil depths of PW plots compared to existing field moist soil conditions. Increase in AWC increased R (as much as 60%) and maximum R rates (as much as 62%), and decreased E (at least 59%) and maximum E rates (as much as 2.1-fold) for corresponding tillage treatments. Compared to CT plots, ST and NT plots decreased R (at least 2.6-fold) and maximum R rates (as much as 3-fold), and decreased E (at least 2.7-fold) and maximum E rates (at least 3.2-fold). Runoff curves for pre-wetted CT and ST plots were always higher than corresponding FM curves, whereas E curves for field moist CT and ST plots were always higher than corresponding PW curves. Changes in AWC and tillage affected detachment and transport processes controlling runoff and sediment yields. A more accurate measure of rainfall partitioning and detachment and transport processes affecting R and E losses was obtained when commonly occurring field conditions (increased AWC with irrigation; I v pattern derived from natural rainfall; commonly used tillage systems) were created and evaluated.

Despite the availability of a vaccine, recent outbreaks in disease-free countries have demonstrated that development of novel FMD control strategies is imperative. Here we report the identification and characterization of bovine (bo) interferon lambda 3 (IFN-[lambda]3), a member of the type III IFN family. Expression of boIFN-[lambda]3 using a replication-defective human adenovirus type 5 vector (Ad5-boIFN-[lambda]3) yielded a glycosylated secreted protein with antiviral activity against FMD virus (FMDV) and vesicular stomatitis virus in bovine cell culture. Inoculation of cattle with Ad5-boIFN-[lambda]3 induced systemic antiviral activity and up-regulation of IFN stimulated gene expression in multiple tissues susceptible to FMDV infection. Our results demonstrate that the type III IFN family is conserved in bovines and boIFN-[lambda]3 has potential for further development as a biotherapeutic candidate to inhibit FMDV or other viruses in cattle.

A. Weber and A. LAPGAPGve is endemic to treeline and alpine habitats of the San Francisco Peaks, Arizona, USA and was listed as a threatened species under the Endangered Species Act in 1983. Species abundance data are limited in scope, yet are critical for recovery of the species, especially in light of predictions of its future extinction due to climate change. This study defined baseline population densities along two transects which will allow the detection of future population trends. Packera franciscana ranged from 3529 to 3722 m elevation along the outer slope transect and densities were 4.18 and 2.74 ramets maa2 in 2008 and 2009, respectively. The overall P. franciscana 2009 density estimate for both transects was 4.36 ramets maa2 within its elevational range of occurrence, 3471aa3722 m. The inner basin density was higher, 5.62 ramets maa2, than the estimate for outer slopes, 2.89 ramets maa2. The elevation of the 2009 population centroid for both transects was at 3586 (A-A-10 SE) m with the inner basin centroid significantly lower than the outer slopes centroid: 3547 (A-A-7 SE) m vs. 3638 (A-A-7 SE) m, respectively. In mid-September, 6aa9%% of the P. franciscana ramets were flowering and/or fruiting in 2008aa2009. These results and our estimate of >36,000 P. franciscana ramets in <2%% of its range would suggest that the species is locally abundant, persisting and reproducing.

Here, we integrate the carrot linkage groups with pachytene chromosomes by fluorescent in situ hybridization (FISH) mapping genetically anchored bacterial artificial chromosomes (BACs). We isolated a satellite repeat from the centromeric regions of the carrot chromosomes, which facilitated the study of the pachytene-based karyotype and demonstrated that heterochromatic domains were mainly confined to the pericentromeric regions of each chromosome. Chromosome-specific BACs were used to: (1) physically locate genetically unanchored DNA sequences, (2) reveal relationships between genetic and physical distances, and (3) address chromosome evolution in Daucus. Most carrot BACs generated distinct FISH signals in 22-chromosome Daucus species, providing evidence for syntenic chromosome segments and rearrangements among them. These results provide a foundation for further cytogenetic characterization and chromosome evolution studies in Daucus.

A population segregating for SBR resistance was evaluated in 2008 and 2009 in Paraguay. In both seasons, F2:3 families were grown in a field naturally infested with SBR. F2:3 families were rated as resistant, segregating, or susceptible on the basis of the lesion type present, and this classification was used to infer the F2-phenotype. Molecular markers flanking five SBR-resistance genes were applied to the F2 population, and markers flanking Rpp3 were significantly associated with the observed resistance (P < 0.0001) in both years. The phenotype of 24-F1 plants evaluated in the 2008 season indicated that the resistance was recessive. This is the first report of recessive resistance at or near the Rpp3 locus. Knowledge of the location and nature of resistance in PI 567099A will allow its more efficient utilization as an SBR-resistance source in breeding programs.

The oxidative stability index at 110 [deg]C was determined for the five oils, and four oils were compared for their stability during storage at 40 [deg]C as determined by peroxide value and hexanal content. The fatty acid composition of all five oils was typical for corn oil. The Acid Value (and percentage of free fatty acids) was highest (28.3 mg KOH/g oil) in corn oil extracted centrifugally from a conventional dry grind ethanol processing facility and for oil extracted, using hexane, from distillers dried grains with solubles (DDGS) from a raw starch ethanol processing facility (20.8 mg KOH/g oil). Acid Value was lowest in two oils extracted centrifugally from thin stillage in a raw starch ethanol facility (5.7 and 6.9 mg KOH/g oil). Tocopherols were highest in corn germ oil (1400 [micro]g/g), but tocotrienols, phytosterols, steryl ferulates, and carotenoids were higher in all of the post-fermentation corn oils. Hexane extracted oil from DDGS was the most oxidatively stable as evaluated by OSI and storage test at 40 [deg]C, followed by centrifugally extracted thin stillage oil from the raw starch ethanol process, and centrifugally extracted thin stillage oil from the conventional dry grind ethanol process. Corn germ oil was the least oxidatively stable. When stored at room temperature, the peroxide value of centrifugally extracted thin stillage oil from the raw starch ethanol process did not significantly increase until after six weeks of storage, and was less than 2.0 mequiv. peroxide/kg oil after three months of storage. These results indicate that post-fermentation corn oils have higher content of valuable functional lipids than corn germ oil.

Eight varieties of beans with average starch content of 46% (db) were assayed in a laboratory-scaled process based upon the commercial corn dry grind fermentation process. Ethanol yield was 0.43-0.51 g ethanol/g glucose (0.19-0.23 g ethanol/g beans). The average ethanol yield for the eight bean types was 92% of maximum theoretical yield, demonstrating that starch from beans could be efficiently converted to ethanol. Ethanol concentration obtained from 20% (w/w) solids loading was 3.5-4.4% (w/v). The residual fermentation solids contained, on a dry basis, 37.1-43.6% crude protein, 10.8-15.1% acid detergent fiber and 19.1-31.3% neutral detergent fiber.

Irrigated agriculture accounts for 80% of total groundwater extracted from the Calera Aquifer. Limited rainfall and low agricultural water use efficiency in combination with fast growing industrial and urban water demand are contributing to groundwater depletion at an unsustainable rate. The main objective of this study was to develop and evaluate a groundwater modeling system using MODFLOW-2000 for the CAR. Predicted groundwater levels were compared with measured data collected from observation wells between 1954 and 2004. Performance statistics indicated that the model performed well in simulating historic groundwater levels in the central part of the CAR where irrigated agriculture is concentrated. However, further improvements in the conceptual model may be needed to improve predictions in other parts of the CAR.

Using E test, 33 isolates were resistant to TET and three isolates to ERY. Using polymerase chain reaction (PCR; single and multiplex), the TET determinants tet(M) and tet(L) were detected in 35 and 13 isolates, respectively. Twelve isolates carried both tet(M) and tet(L) genes. Eight isolates possessed ermB gene associated with ERY resistance. Multiplex PCR was shown to be a suitable method for simultaneous determination of all three resistance determinants that occurred most frequently in bacteria isolated from poultry. This study also demonstrates that gastrointestinal tract of broilers may be a reservoir of enterococci with acquired resistance to both TET and ERY that can be transferred to humans via food chain.

Two principal methods for gene replacement were established. The first "in-out" method is based on integration of plasmid into bacterial chromosome and subsequent resolving of the cointegrate. The "linear fragment" method (recombineering) is based on homologous recombination mediated by short homology arms at the ends of linear DNA molecule. Many new protocols and improvements in targeted gene replacement were introduced during the last 10 years. These methods are well suited for high-throughput functional gene studies and for many biotechnological applications.

AN - 893275114; 14933920 AB - The Casuarina spp. are invasive plants in Florida that threaten biological diversity and beach integrity of coastal habitats. The trees include three species and their hybrids that aggressively invade riverine and coastal areas. Of the three species, C. equisetifolia and C. glauca are highly salt tolerant and widespread in coastal areas. The third species, C. cunninghamiana, invades riverine habitats. These species pose dangers to both the environment and public safety. The environmental damage includes interfering with nesting by endangered sea turtles, American crocodiles, and the rare swallow-tailed kite. Additionally, allelochemical leachates reduce germination and establishment of native vegetation. Casuarina-infested beaches are more prone to sand loss and erosion. Moreover, with shallow roots and tall canopies, they are among the first trees to fall in high winds and as such restrict evacuation efforts during hurricanes. Control of these species is mostly with herbicides, requiring repeated applications and monitoring. One of the most cost-effective means of controlling these invasive species would be with classical biological control. Australian surveys for potential biological control agents began in 2004, resulting in the discovery of several promising candidates. These include seed-feeding torymid wasps, defoliating caterpillars and weevils, leaf tip gall-formers from cecidomyiid midges, and sap-feeding psyllids. Continued work is needed to determine the suitability of these species for biological control. Despite conflicts of interest expressed by some homeowners and the agricultural industry who value the trees for shade and windbreaks, there are good prospects for safe and effective biological control of these invasive species.

There is insufficient evidence to conclude that terpenoid profiles or humidity influence B. melaleucae development. Although longevity of adult psyllids is greater on plants that contain E-nerolidol versus viridiflorol profiles, this does not translate to a longer ovipositional period or increased fecundity. Similarly, humidity treatments had a limited and inconsistent effect on B. melaleucae developmental rates and nymphal survivorship. In contrast, developmental rates increased linearly with increasing temperature to an optimum 25 degree C, whereas greater temperatures caused total developmental rates to decrease. Temperature also affected nymphal survivorship, with no individuals completing development below 10 or above 30 degree C. Mean maximum daily temperatures in southern Florida commonly exceeded 30 degree C, with maximum temperatures ranging from 30 to 35 degree C (in Broward Co.) during 138 d in 2006. Therefore, we conclude that lethal upper temperature thresholds will limit population growth rates during summer.

The full-length mRNA sequence (890 bp) for trypsin from Ae. taeniorhynchus (AetTryp1) was obtained, which encodes an open reading frame of 765 bp (i.e., 255 amino acids). To detect whether AetTryp is developmentally regulated, a quantitative real-time polymerase chain reaction was used to examine AetTryp1 mRNA expression levels in different developmental stages of Ae. taeniorhynehus. AetTryp1 was expressed at low levels in egg, larval, and pupal stages, but was differentially expressed in adult Ae. taeniorhynchus, with highest levels found in 5-d-old female adults when compared with teneral adults. In addition, AetTryp1 mRNA expression differed between sexes, with expression levels much lower in males. However, in both males and females, there was a significant increase in AetTryp1 transcription levels as age increased and peaked in 5-d-old adults. AetTryp1 expressed in 5-d-old female Ae. taeniorhynchus significantly increased after 30 min postblood feeding compared with the control. The AetTryp1 mRNA expression in 5-d-old female Ae. taeniorhynchus was affected by different concentrations of permethrin.

Females from the Orlando and the F0 through F10 generations of the Puerto Rico strain were evaluated using attractant odors in a triple-cage dual-port olfactometer. Two attractant sources were used: odors from the hand of a volunteer and a standard blend of L-lactic acid, acetone, and dimethyl disulfide. Convergence of the percentage of attraction responses occurred around the F4--F6 generations of the Puerto Rico strain. Both the Orlando and Puerto Rico strains exhibited similar responses for tests with the remaining F7--F10 generations. A temporal effect on mosquito responses was observed for both strains regardless of the attractant blend used in tests. This study indicates that Ae. aegypti host-seeking behavior changes significantly over the first four to six generations after introduction into the laboratory, whereas the field-collected strain increases in attraction response until it stabilizes at a new level.

The Forest Inventory and Analysis (FIA) program is a national monitoring program for all public and private forestlands in the US, but the program is not currently implemented in the boreal region of Alaska. We provide an overview of the strengths and weaknesses of the FIA system for monitoring the potential impact of climate change on Alaska's species, communities, and ecosystems. The primary strength of the system is a scientifically rigorous design-based statistical estimation method that produces estimates of forest attributes with known sampling error and quantifiable measurement error. The weaknesses of the system include low power for small area estimates, lack of spatial context and contiguity, and difficulty in inferring causality of factors when changes in monitored attributes are detected. Climate change is expected to impact many components of boreal ecosystems, but for most indicators the direction and magnitude of change are difficult to predict because of complex interactions among system components. Status and trend information provided by FIA monitoring that could be helpful to conservation decisions includes abundance and rarity of vascular plants, invasive species, biomass and carbon content of vegetation, shifting vegetation species distribution, disturbance frequency, type, and impact, and wildlife habitat characteristics. Because of unique factors such as the low level of infrastructure, modifications to the FIA monitoring system used in the conterminous US have been proposed for Alaska. Remote sensing data would play a greater role in meeting monitoring objectives, and sampling intensity of field plots would be reduced. Coordination with other national, regional, and local monitoring efforts provides potential for increased understanding of change in boreal ecosystems at multiple scales.

Although this competition is known to be influenced by several biotic and abiotic factors, relatively few data are available from highly altered landscapes. We investigated the fate of mouse carcasses in an intensively farmed region in Indiana, USA, using remote cameras. Vertebrates removed 234 of 266 (88%) carcasses within two weeks after placement. Raccoons (Procyon lotor) and Virginia opossums (Didelphis virginiana) were the predominant scavengers, removing 184 of 197 (93%) carcasses for which a scavenger could be identified. Air temperature influenced carcass removal by vertebrates only at higher temperatures, with fewer carcasses removed as temperatures increased over a arrow right 422A degree C. Elevated densities of mesopredators, coupled with the reduced search area for carrion due to the sparse distribution of forested habitat, likely were responsible for the rapid discovery and high level of carcass removal by vertebrates compared to previous investigations. Our data suggest that in agricultural landscapes, the competitive balance for carrion can differ substantially from that found in more pristine habitats. Moreover, the monopolization of carrion resources by abundant mesopredators may have negative consequences for other species that use carrion.Original Abstract: Die Rolle von Aas in Nahrungsnetzen wird von komplexen Konkurrenzbeziehungen zwischen einer Vielzahl von Taxa bestimmt. Obwohl bekannt ist, dass diese Konkurrenz von verschiedenen biotischen und abiotischen Faktoren beeinflusst wird, gibt es relativ wenige Daten aus stark veraenderten Landschaften. Wir untersuchten das Schicksal von Maeusekadavern in einer intensiv bewirtschafteten Agrarregion in Indiana, USA, und benutzten dafuer fernausgeloeste Kameras. Wirbeltiere entfernten 234 von 266 (88%) Kadavern innerhalb von zwei Wochen nach dem Auslegen. Waschbaeren (Procyon lotor) und Virginia-Opossums (Didelphis virginiana) waren die dominanten Aasfresser, und sie entfernten 184 von 197 (93%) Kadavern, bei denen der Aasfresser identifiziert werden konnte. Die Lufttemperatur hatte einen Einfluss: Ab etwa 22A degree C wurden weniger Kadaver weggeraeumt. Erhoehte Dichten von Mesopraedatoren, verbunden mit einem durch die spaerliche Verteilung der Gehoelzhabitate eingeschraenkten Suchareal, waren wahrscheinlich dafuer verantwortlich, dass die Kadaver verglichen mit frueheren Untersuchungen schnell entdeckt und zu einem hohen Prozentsatz von Wirbeltieren entfernt wurden. Unsere Daten legen nahe, dass in Agrarlandschaften das Konkurrenzgleichgewicht der Aasnutzer erheblich von dem in eher urspruenglichen Habitaten abweicht. Darueberhinaus koennte die Monopolisierung des Aases durch haeufige Mesopraedatoren negative Konsequenzen fuer andere Arten, die Aas nutzen, haben.

The corn earworm feeds readily on both monocots and dicots, while the fall armyworm is primarily a grass feeder. Most of the saponins were similarly effective or ineffective against both insect species, with the glycosides being the primary active form (compared to aglycones). However, one aglycone possessed antifeedant properties toward the fall armyworm. Thus, in contrast to many plant secondary metabolites effective against either of these two species where the aglycone is more effective, in the case of the saponins the opposite is generally true. This appears to be a contradictory strategy of plant defenses that requires further consideration. The activity of protodioscin against insects is reported for the first time and may be important in insect defense by the bioenergy crop switchgrass.

A similar response is elicited by plant substances that contain alpha -copaene, a naturally-occurring sesquiterpene. alpha -Copaene is a complex, highly-volatile, widely-distributed plant compound, and male C. capitata respond to material from both hosts (e.g., Litchi chinensis) and non-hosts (e.g., Ficus benjamina) that contain alpha -copaene. Avocado, Persea americana, recently was found to contain varying amounts of alpha -copaene in the bark and underlying cambial tissue. Short-range attraction bioassays and electroantennography (EAG) were used to quantify responses of sterile male C. capitata to samples of rasped wood from four avocado genotypes, L. chinensis, and F. benjamina. Gas chromatography-mass spectral (GC-MS) analysis was used to identify and quantify the major sesquiterpenes. Attraction and EAG amplitude were correlated, with L. chinensis eliciting the highest and F. benjamina the lowest responses. Responses to the avocado genotypes were intermediate, but varied among the four types. GC-MS identified 13 sesquiterpenes, including alpha -copaene, from all samples. Amounts of alpha -copaene in volatile collections from samples (3g) ranged from 11.8 mu g in L. chinensis to 0.09 mu g in F. benjamina, which correlated with short-range attraction and EAG response. alpha -Copaene ranged from 8.0 to 0.8 mu g in the avocado genotypes, but attraction and EAG responses were not correlated with the amount of alpha -copaene. Differences in enantiomeric structure of the alpha -copaene in the different genotypes and/or presence of additional sesquiterpenes may be responsible for the variation in male response. EAG responses were correlated with the amount of several other sesquiterpenes including alpha -humulene, and this compound elicited a strong antennal response when tested alone.

These attracting cues are related not only to current conditions, but also are a reflection of individual and population life history. These relationships were examined by placing red flour beetle, Tribolium castaneum (Herbst.), adults in flasks at increasing densities and monitoring the changes in volatile chemical emission over time. Only certain chemicals were quantified: methyl benzoquinone, ethyl benzoquinone and 4,8-dimethyldecanal, all of which are known to impact the biology of T. castaneum. The flasks were used as sources for both quantification of the chemicals and for bioassays. Additional bioassays were conducted with synthetic 4,8-dimethyldecanal, a known aggregation pheromone component, to evaluate attraction with respect to population density. Tribolium castaneum density affected both the release of volatile chemicals and the responses of conspecifics to those chemicals. The results indicated that while there were important effects of beetle density on chemical emission and response, none of the chemicals evaluated emerged as promising synergists to the current aggregation pheromone 4,8-dimethyldecanal. The benzoquinones released in response to stress and density acted as anti-aggregation pheromones along with their accepted defensive function.

We have reported an APOA2-saturated fat interaction determining body mass index (BMI) and obesity in American populations. This work aims to extend our findings to European and Asian populations. Methods: Cross-sectional study in 4602 subjects from two independent populations: a high-cardiovascular risk Mediterranean population (n=907 men and women; aged 67+/-6 years) and a multiethnic Asian population (n=2506 Chinese, n=605 Malays and n=494 Asian Indians; aged 39+/-12 years) participating in a Singapore National Health Survey. Anthropometric, clinical, biochemical, lifestyle and dietary variables were determined. Homeostasis model assessment of insulin resistance was used in Asians. We analyzed gene-diet interactions between the APOA2 -265T>C polymorphism and saturated fat intake (C polymorphism on body-weight-related measures was modulated by saturated fat in Mediterranean and Asian populations.

Due to its surface application in conservation tillage systems and high solubility, the soluble components of gypsum may be transferred with agricultural runoff into receiving waters. The current study measured toxicity of gypsum to Ceriodaphnia dubia, Pimephales promelas, Chironomus dilutus, and Hyalella azteca. Solutions at 2,400 mg gypsum/L (maximum solubility) produced no observable toxicity to C. dubia and P. promelas. Mixtures of a control sediment and gypsum indicated no observed toxicity effects for H. azteca, although effects were noted at 25% dilution for C. dilutus. Data suggest gypsum is not harmful to freshwater organisms at concentrations expected in the agricultural environment.

Sequence analysis of the 16S-23S rDNA intergenic spacer region (ISR), cpn60, gyrB, and rpoD genes of the 3 strains revealed that the 3 strains were closely related to each other, sharing 97 to 99% nucleotide sequence similarities. However, ISR sequences of the 3 isolates from 2009 shared only 64% nucleotide sequences with AL98-C1B, a 1998 isolate of A. hydrophila cultured from diseased fish in Alabama. Sequences of cpn60, gyrB, and rpoD from the 3 isolates from 2009 shared 91 to 95% homologies with AL98-C1B. Based on both LD sub(50) and LD sub(95) values of intraperitoneal injection assays, the virulences of the 3 isolates from 2009 were not significantly different from each other, but were at least 200-fold more virulent than AL98-C1B, indicating that the 3 west Alabama isolates of A. hydrophila from 2009 were highly virulent to channel catfish.

Disease-suppressive rotations consisted of: (i) a high-glucosinolate mustard blend ('Caliente 119') as a mixture of white mustard (Sinapis alba) and oriental mustard (Brassica juncea) with known biofumigation potential and (ii) a sorghum-sudangrass hybrid. Each were grown as single-season green manures followed by a subsequent potato crop. These rotations were compared with a standard barley rotation and a barley rotation followed by chemical fumigation with metam sodium as controls. Both green manure rotations significantly reduced (average reductions of 25 and 18%, respectively) Verticillium wilt in the subsequent potato crop compared with the standard barley control but were not as effective as chemical fumigation (35% reduction). The mustard blend also reduced other soilborne diseases (black scurf and common scab) better than all other rotations. Mustard blend and chemical fumigation treatments increased tuber yield relative to the barley control by 12 and 18%, respectively. However, by the second rotation cycle, disease levels were high in all rotations, and only chemical fumigation resulted in substantial disease reduction (35%). Rotations also had significant effects on soil microbiology, including soil bacterial and fungal populations and microbial community characteristics based on fatty acid profiles. However, only chemical fumigation significantly reduced soil populations of Verticillium spp. and increased general soil microbial activity. Previous cropping history did not significantly affect disease reduction, tuber yield, or soil microbial communities. This research indicates the potential for using disease-suppressive rotations for managing Verticillium wilt and other soilbome diseases but also indicates that multiple years of disease-suppressive crops may be needed to substantially reduce disease in heavily infested fields.

Despite the prevalence and importance of these pathogens in forest nurseries, relatively little is known about the identity of Pythium species associated with forest nursery soils in Washington and Oregon. A limited number of studies have reported P. aphanidermatum, P. irregulare, P. mamillatum, and P. ultimum as the predominant species in the PNW, but most studies of this genus in forest nurseries have not reported Pythium species identity. In an attempt to identify Pythium species associated with forest nursery soils, field surveys were conducted at three forest nurseries (two in Oregon and one in Washington) in 2008 using three isolation methods. Pythium species were isolated by plating soil onto a semiselective medium or by baiting soil with rhododendron leaf disks and Douglas-fir needle segments. One hundred isolates were randomly selected from each isolation method at each nursery (900 isolates total) and identified on the basis of the internal transcribed spacer (ITS) sequence. Nineteen Pythium species were identified during the survey. Species richness and abundance were strongly influenced by both nursery and isolation method. Of the 300 isolates obtained from each nursery, P. irregulare was the most commonly isolated species from nursery A in Washington (65% incidence). P. 'vipa' and P. dissotocum were the most commonly isolated species from nurseries B and C in Oregon, respectively (53 and 47% incidence, respectively).

High ratios of pellets to peat (>50%) may be less desirable because of high C:N, high bulk density, swelling associated with water absorption, and low volumetric water content, whereas a mixture of 75% peat and 25% pellets had enhanced hydraulic conductivity and greater water availability at lower (<-10 kPa) matric potentials. Adding pellets to substrates used to grow plants in nurseries has potential to add value to biochar and thereby improve economic viability of pyrolysis. Moreover, biochar-amended substrates offer opportunity to sequester carbon as part of the normal outplanting process.

The purpose of this paper was to assess the FV consumption to adiposity relationship. Twenty-three publications were included. Inclusion criteria: longitudinal or experimental designs; FV intake tested in relation to adiposity; child, adolescent or adult participants; published in English-language peer-reviewed journals. Exclusion criteria: dietary pattern and cross-sectional designs; participants with health concerns. Experimental studies found increased FV consumption (in conjunction with other behaviours) contributed to reduced adiposity among overweight or obese adults, but no association was shown among children. Longitudinal studies among overweight adults found greater F and/or V consumption was associated with slower weight gain, but only half of child longitudinal studies found a significant inverse association. Limitations in methods prevented a thorough examination of the role of increased FV intake alone or mechanisms of effect. An inverse relationship between FV intake and adiposity among overweight adults appears weak; this relationship among children is unclear. Research needs to clarify the nature of, and mechanisms for, the effects of FV consumption on adiposity. Whether increases in FV intake in isolation from lower caloric intake or increased physical activity will result in declines or slower growth in adiposity remains unclear.

Alligator weed, Alternanthera philoxeroides, is a South American amphibious Amaranthaceae, which invades aquatic and terrestrial habitats. Populations with varying morphotypes and cytotypes were identified and further associated with a polyploid hybrids complex in Argentina, which probably is the centre of origin and diversification of alligator weed. The current model of the hybrid complex formation proposes that diploid ancestors gave rise to allotetraploids and allohexaploids. Agasicles hygrophila is a monophagous chrysomelid beetle which successfully controls A. philoxeroides in regions with mild winters and where the weed grows in aquatic habitats. However, plant genetic characteristics could constrain insect development and reproduction, providing an alternative explanation for the restricted success of biological control of alligator weed with A. hygrophila. We investigated the effect of four A. philoxeroides populations with varying cytogenetical characteristics on plant-insect interaction with A. hygrophila in the native range of the weed. The insect's life cycle on each host population was studied. In addition, the genetic relationships among the weed populations was explored using dot blot analysis. Plant population affected insect survival and fecundity, but not life cycle length nor third larval instar mortality, pupal mortality or female proportion. Plant internode diameter was not a restriction for insect pupation. All hexaploid populations of A. philoxeroides, as well as the close related A. aquatica, hybridized with the tetraploid population probe with similar intensity, meaning that this population is a component of their polyploid genome.

The RB type of resistance can be incomplete, as evidenced by the presence of sporulating uredinia within lesions. Susceptibility, on the other hand, is exemplified by tan-colored (TAN) lesions, and can be expressed in gradations of susceptibility or partial resistance that are less well defined. This study evaluated traits associated with incomplete or partial resistance to P. pachyrhizi in soybean by comparing 34 soybean accessions inoculated with four P. pachyrhizi isolates. Six accessions produced RB lesions to all four isolates, while 19 accessions produced TAN lesions, including plant introduction (PI) 200492 (Rpp1) and the susceptible check 'Williams'. Williams had among the largest area under the disease progress curve (AUDPC) values and area under the sporulating uredinia progress curve (AUSUPC) values, while eight accessions had lower AUSUPC values. Of the known sources of single-gene resistance, only PI 230970 (Rpp2), PI 459025B (Rpp4), and PI 594538A (Rpplb) had lower AUDPC and AUSUPC values than Williams. PI 594538A and PI 561356 had RB lesions and had the lowest AUDPC and AUSUPC values. Of the known sources of single-gene resistance, only PI 230970 (Rpp2) and PI 594538A (Rpplb) produced fewer and smaller-diameter uredinia than Williams. This study characterized reactions to P. pachyrhizi in 34 accessions based on lesion type and sporulation, and defined incomplete resistance and partial resistance in the soybean-P. pachyrhizi interaction.

Over the last several years, scientists have discovered the benefit of using edge-of-field practices, such as vegetated agricultural drainage ditches, in the mitigation of pesticides and sediment. After demonstrating this practice's feasibility in California, field trials were initiated to document irrigation runoff pesticide mitigation in California alfalfa and tomato fields. In the alfalfa field, chlorpyrifos concentration was decreased by 20% from the inflow to the ditch outflow. Thirty-two percent of the measured chlorpyrifos mass was associated with ditch plant material. In the tomato field, permethrin concentration was decreased by 67% and there was a 35% reduction in suspended sediment concentration from inflow to the ditch outflow. When surface water was not present in the ditch systems, the sediment was a significant repository for pesticides. Based on the field trials, vegetated agricultural drainage ditches can be successfully used as part of a suite of management practices to reduce pesticide and sediment runoff into aquatic receiving systems.

The outbreak was limited to a four-county region in southern Pennsylvania. Initial serological and molecular characterization indicated that the isolates in Pennsylvania belong to the D strain of PPV. The Pennsylvania isolates were characterized by sequence analysis, electron microscopy, host range, and vector transmission to determine how these isolates related to their previously studied European counterparts. Genetically, Pennsylvania (PPV-Penn) isolates were more closely related to each other than to any other PPV-D strains, and isolates from the United States, Canada, and Chile were more closely related to each other than to European isolates. The PPV-Penn isolates exist as two clades, suggesting the possibility of multiple introductions. Electron microscopy analysis of PPV-Penn isolates, including cytopathological studies, indicated that the virions were similar to other Potyvirus spp. PPV-Penn isolates had a herbaceous host range similar to that of European D isolates. There were distinct differences in the transmission efficiencies of the two PPV-Penn isolates using Myzus persicae and Aphis spiraecola as vectors; however, both PPV-Penn isolates were transmitted by M. persicae more efficiently than a European D isolate but less efficiently than a European M isolate.

Data were collected on diaphragm and helical pumps which were powered by different solar PV arrays at multiple pumping depths to determine the pumping performance, efficiency, and reliability of the different systems. The highest diaphragm pump hydraulic efficiency measured was 48%, and the highest helical pump hydraulic efficiency measured was 60%. The peak total system efficiency (e.g. solar radiation to pumped water) measured for the diaphragm and helical pumps were 5% and 7%, respectively (based on PV modules with 12% efficiency). The daily water volume of the three-chamber high head diaphragm pump performed better than the dual-chamber high head diaphragm pump (5 to 100% depending on PV array input power and pumping depth). Use of a controller was shown to improve the quad diaphragm pump performance below a solar irradiance of 600 W/m super(2) (20 m head) to 800 W/m super(2) (30 m head). While diaphragm pumps made mostly of plastic demonstrated similar to much better pumping performance than diaphragm pumps made with a high proportion of metal, the metal pumps demonstrated a longer service life (>2 years) than the plastic pumps service life (<2 years). Helical pumps analyzed in this paper were capable of deeper pumping depths and usually demonstrated a longer service life than the diaphragm pumps that were analyzed.

The soybean genes Rpp3 and Rpp?(Hyuuga) confer resistance to specific isolates of the pathogen. Both genes map to chromosome 6 (Gm06) (linkage group [LG] C2). We recently identified 12 additional soybean accessions that harbor ASR resistance mapping to Gm06, within 5 centimorgans of Rpp3 and Rpp?(Hyuuga). To further characterize genotypes with resistance on Gm06, we used a set of eight P. pachyrhizi isolates collected from geographically diverse areas to inoculate plants and evaluate them for differential phenotypic responses. Three isolates elicited different responses from soybean accessions PI 462312 (Ankur) (Rpp3) and PI 506764 (Hyuuga) (Rpp?[Hyuuga]). In all, 11 of the new accessions yielded responses identical to either PI 462312 or Hyuuga and 1 of the new accessions, PI 417089B (Kuro daizu), differed from all others. Additional screening of Hyuuga-derived recombinant inbred lines indicated that Hyuuga carries two resistance genes, one at the Rpp3 locus on Gm06 and a second, unlinked ASR resistance gene mapping to Gm03 (LG-N) near Rpp5. These findings reveal a natural case of gene pyramiding for ASR resistance in Hyuuga and underscore the importance of utilizing multiple isolates of P. pachyrhizi when screening for ASR resistance.

Pasteurized apple cider without preservatives was inoculated with L. plantarum and processed using a SCCO2 system at a CO2 concentration range of 0-12% (g CO2/100g product), outlet temperatures of 34, 38, and 42 degree C, a system pressure of 7.6MPa, and a flow rate of 1 L/min. Processing with SCCO2 significantly (P <0.05) enhanced inactivation of L. plantarum in apple cider, resulting in a 5 log reduction with 8% CO2 at 42 degree C. The response surface model indicated that both CO2 concentration and temperature contributed to the microbial inactivation. The extent of sublethal injury in surviving cells in processed apple cider increased as CO2 concentration and processing temperature increased, however the percent injury dramatically decreased during SCCO2 processing at 42 degree C. Structural damage in cell membranes after SCCO2 processing was observed by SEM. Refrigeration (4 degree C) after SCCO2 processing effectively inhibited the re-growth of surviving L. plantarum during storage for 28 days. Thus this study suggests that SCCO2 processing is effective in eliminating L. plantarum and could be applicable for nonthermal pasteurization of apple cider.

Studies on the vertical distribution patterns of arthropods in temperate deciduous forests reveal highly stratified (i.e., unevenly vertically distributed) communities. These patterns are determined by multiple factors acting simultaneously, including: (1) time (forest age, season, time of day); (2) forest structure (height, vertical foliage complexity, plant surface textures, tree cavities); (3) plant community composition (plant diversity, invasive species); (4) climatic gradients (light exposure, temperature, wind speed, humidity); (5) resource availability (foliage, sugars, wood, epiphytes, carrion, dung, prey, hosts, mates); (6) inter-specific interactions (predation, interference, competition) and (7) logistics (dispersal abilities, proximity to emergence sites, open flight zones). Several recommendations can be made with respect to incorporating canopy habitats and resources into management plans in order to maintain diverse forest arthropod communities. Efforts should be made to maintain diverse plant communities, for instance, including eliminating or controlling invasive plant competitors. Protecting large diameter trees and snags is also important, especially for a wide variety of canopy arthropod taxa associated with standing or suspended dead wood, tree cavities and epiphytes. Finally, it is essential to ensure adequate spatial and temporal continuity in the availability of these and other key resources. Although how to best achieve this last objective remains an active area of research, it may be preferable to retain clusters of trees as opposed to isolated individuals.

AN - 865188419; 21321255 AB - Mutagenized populations have become indispensable resources for introducing variation and studying gene function in plant genomics research. In this study, fast neutron (FN) radiation was used to induce deletion mutations in the soybean (Glycine max) genome. Approximately 120,000 soybean seeds were exposed to FN radiation doses of up to 32 Gray units to develop over 23,000 independent M2 lines. Here, we demonstrate the utility of this population for phenotypic screening and associated genomic characterization of striking and agronomically important traits. Plant variation was cataloged for seed composition, maturity, morphology, pigmentation, and nodulation traits. Mutants that showed significant increases or decreases in seed protein and oil content across multiple generations and environments were identified. The application of comparative genomic hybridization (CGH) to lesion-induced mutants for deletion mapping was validated on a midoleate x-ray mutant, M23, with a known FAD2-1A (for fatty acid desaturase) gene deletion. Using CGH, a subset of mutants was characterized, revealing deletion regions and candidate genes associated with phenotypes of interest. Exome resequencing and sequencing of PCR products confirmed FN-induced deletions detected by CGH. Beyond characterization of soybean FN mutants, this study demonstrates the utility of CGH, exome sequence capture, and next-generation sequencing approaches for analyses of mutant plant genomes. We present this FN mutant soybean population as a valuable public resource for future genetic screens and functional genomics research.

AN - 863902326; 21521823 AB - Death camas (Zigadenus spp.) is a common poisonous plant on foothill rangelands in western North America. The steroidal alkaloid zygacine is believed to be the primary toxic component in death camas. Poisonings on rangelands generally occur in the spring when death camas is abundant, whereas other more desirable forage species are limited in availability. In most cases where livestock are poisoned by plants in a range setting, there is more than one potential poisonous plant in that area. One common poisonous plant that is often found growing simultaneously in the same area as death camas is low larkspur (Delphinium nuttallianum). Consequently, the objectives of this study were to conduct acute toxicity studies in mice and to determine if coadministration of low larkspur will exacerbate the toxicity of death camas. We first characterized the acute toxicity of zygacine in mice. The LD(50) of zygacine administered intravenously (i.v.) and orally was 2.0 ± 0.2 and 132 ± 21 mg/kg, respectively. The rate of elimination of zygacine from whole blood was determined to be 0.06 ± 0.01/min, which corresponds to an elimination half-life of 13.0 ± 2.7 min. The i.v. LD(50) of total alkaloid extracts from a Utah and a Nevada collection were 2.8 ± 0.8 and 2.2 ± 0.3 mg/kg, respectively. The i.v. LD(50) of methyllycaconitine (MLA), a major toxic alkaloid in low larkspur, was 4.6 ± 0.5 mg/kg, whereas the i.v. LD(50) of a 1:1 mixture of MLA and zygacine was 2.9 ± 0.7 mg/kg. The clinical signs in mice treated with this mixture were very similar to those of mice treated with zygacine alone, including the time of onset and death. These results suggest that there is an additive effect of coadministering these 2 alkaloids i.v. in mice. The results from this study increase knowledge and understanding regarding the acute toxicity of death camas. As combined intoxications are most likely common, this information will be useful in further developing management recommendations for ranchers and in designing additional experiments to study the toxicity of death camas to livestock.

AN - 862279400; 21380517 AB - Pretreatment of lignocellulose biomass for biofuel production generates inhibitory compounds that interfere with microbial growth and subsequent fermentation. Remediation of the inhibitors by current physical, chemical, and biological abatement means is economically impractical, and overcoming the inhibitory effects of lignocellulose hydrolysate poses a significant technical challenge for lower-cost cellulosic ethanol production. Development of tolerant ethanologenic yeast strains has demonstrated the potential of in situ detoxification for numerous aldehyde inhibitors derived from lignocellulose biomass pretreatment and conversion. In the last decade, significant progress has been made in understanding mechanisms of yeast tolerance for tolerant strain development. Enriched genetic backgrounds, enhanced expression, interplays, and global integration of many key genes enable yeast tolerance. Reprogrammed pathways support yeast functions to withstand the inhibitor stress, detoxify the toxic compounds, maintain energy and redox balance, and complete active metabolism for ethanol fermentation. Complex gene interactions and regulatory networks as well as co-regulation are well recognized as involved in yeast adaptation and tolerance. This review presents our current knowledge on mechanisms of the inhibitor detoxification based on molecular studies and genomic-based approaches. Our improved understanding of yeast tolerance and in situ detoxification provide insight into phenotype-genotype relationships, dissection of tolerance mechanisms, and strategies for more tolerant strain development for biofuels applications.

AN - 861202894; 21268232 AB - Environmental impacts and resistance to insecticides pose serious challenges to stored-product insect and other types of pest control. Insect-resistant transgenic grain is a potential alternative to fumigants, but candidate control proteins are needed, especially for coleopterans. Therefore, we evaluated the efficacy of a coleopteran-active toxin, Bacillus thuringiensis Cry3Aa, with or without protease inhibitors, in laboratory feeding assays against coleopteran storage pests. In a comparison of the toxicity of Cry3Aa protoxin towards three species of coleopteran storage pests, Tenebrio molitor L. was found to be most sensitive, Tribolium castaneum (Herbst.) was most refractory and Rhyzopertha dominica F. displayed an intermediate response. For R. dominica, Cry3Aa combined with 3500 mg potato carboxypeptidase inhibitor or 5000 mg aprotinin kg(-1) diet resulted in both delayed development and increased mortality. Potato carboxypeptidase inhibitor and bovine aprotinin reduced the LC(50) of Cry3Aa for R. dominica two- and threefold respectively. Cry3Aa treatment resulted in fewer progeny from R. dominica, and progeny was further reduced when the protoxin was combined with potato carboxypeptidase inhibitor.

AN - 856173041; 21216300 AB - Certain Fusarium species cause head blight of wheat and other small grains worldwide and produce trichothecene mycotoxins. These mycotoxins can induce toxicoses in animals and humans and can contribute to the ability of some fusaria to cause plant disease. Production of the trichothecene 3-acetyldeoxynivalenol (3-ADON) versus 15-acetyldeoxynivalenol (15-ADON) is an important phenotypic difference within and among some Fusarium species. However, until now, the genetic basis for this difference in chemotype has not been identified. Here, we identified consistent DNA sequence differences in the coding region of the trichothecene biosynthetic gene TRI8 in 3-ADON and 15-ADON strains. Functional analyses of the TRI8 enzyme (Tri8) in F. graminearum, the predominant cause of wheat head blight in North America and Europe, revealed that Tri8 from 3-ADON strains catalyzes deacetylation of the trichothecene biosynthetic intermediate 3,15-diacetyldeoxynivalenol at carbon 15 to yield 3-ADON, whereas Tri8 from 15-ADON strains catalyzes deacetylation of 3,15-diacetyldeoxynivalenol at carbon 3 to yield 15-ADON. Fusarium strains that produce the trichothecene nivalenol have a Tri8 that functions like that in 15-ADON strains. TRI3, which encodes a trichothecene carbon 15 acetyltransferase, was found to be functional in all three chemotypes. Together, our data indicate that differential activity of Tri8 determines the 3-ADON and 15-ADON chemotypes in Fusarium. Published by Elsevier Inc.

AN - 854565402; 21356437 AB - This study examined the growth characteristics of Listeria monocytogenes as affected by a native microflora in cooked ham at refrigerated and abuse temperatures. A five-strain mixture of L. monocytogenes and a native microflora, consisting of Brochothrix spp., isolated from cooked meat were inoculated alone (monocultured) or co-inoculated (co-cultured) onto cooked ham slices. The growth characteristics, lag phase duration (LPD, h), growth rate (GR, log(10) cfu/h), and maximum population density (MPD, log(10) cfu/g), of L. monocytogenes and the native microflora in vacuum-packed ham slices stored at 4, 6, 8, 10, and 12 °C for up to 5 weeks were determined. At 4-12 °C, the LPDs of co-cultured L. monocytogenes were not significantly different from those of monocultured L. monocytogenes in ham, indicating the LPDs of L. monocytogenes at 4-12 °C were not influenced by the presence of the native microflora. At 4-8 °C, the GRs of co-cultured L. monocytogenes (0.0114-0.0130 log(10) cfu/h) were statistically but marginally lower than those of monocultured L. monocytogenes (0.0132-0.0145 log(10) cfu/h), indicating the GRs of L. monocytogenes at 4-8 °C were reduced by the presence of the native microflora. The GRs of L. monocytogenes were reduced by 8-7% with the presence of the native microflora at 4-8 °C, whereas there was less influence of the native microflora on the GRs of L. monocytogenes at 10 and 12 °C. The MPDs of L. monocytogenes at 4-8 °C were also reduced by the presence of the native microflora. Data from this study provide additional information regarding the growth suppression of L. monocytogenes by the native microflora for assessing the survival and growth of L. monocytogenes in ready-to-eat meat products.

The results indicate a significant difference between the observed soil CH sub(4) oxidation at field sampled conditions compared to optimum conditions achieved through pre-incubation (60 days) in the presence of CH sub(4) (50 ml l super(-1)) and soil moisture optimization. This pre-incubation period normalized CH sub(4) oxidation rates to within the same order of magnitude (112-644 mu g CH sub(4) g super(-1) day super(-1)) for all the cover soils samples examined, as opposed to the four orders of magnitude variation in the soil CH sub(4) oxidation rates without this pre-incubation (0.9-277 mu g CH sub(4) g super(-1) day super(-1)). Using pre-incubated soils, a minimum soil moisture potential threshold for CH sub(4) oxidation activity was estimated at 1500kPa, which is the soil wilting point. From the laboratory incubations, 50% of the oxidation capacity was inhibited at soil moisture potential drier than 700kPa and optimum oxidation activity was typical observed at 50kPa, which is just slightly drier than field capacity (33kPa). At the extreme temperatures for CH sub(4) oxidation activity, this minimum moisture potential threshold decreased (300kPa for temperatures 40A degree C), indicating the requirement for more easily available soil water. However, oxidation rates at these extreme temperatures were less than 10% of the rate observed at more optimum temperatures (~30 degree C). For temperatures from 5 to 40 degree C, the rate of CH sub(4) oxidation was not limited by moisture potentials between 0 (saturated) and 50kPa. The use of soil moisture potential normalizes soil variability (e.g. soil texture and organic matter content) with respect to the effect of soil moisture on methanotroph activity. The results of this study indicate that the wilting point is the lower moisture threshold for CH sub(4) oxidation activity and optimum moisture potential is close to field capacity. No inhibitory effects of elevated CO sub(2) soil gas concentrations were observed on CH sub(4) oxidation rates. However, significant differences were observed for diurnal temperature fluctuations compared to thermally equivalent daily isothermal incubations.

Soils were collected from a large-scale biosolids recycling operation that surface-applies anaerobically digested Class B biosolids for commercial forage production. Five treatments were evaluated: unamended control; 22Mgdrybiosolidsha-1 y-1 applied for 25 years; 22, 45, and 67Mgha-1 y-1 applied for 8 years. Biosolids additions enhanced total soil organic C by 32-92% and total N by 30-157% compared to unamended soils. Total N increased with application rate and was dominated by nitrate-N. Potential C mineralization (cumulative CO2 produced) was 11-62% greater in amended soils compared to controls and highest at 67Mgha-1 y-1. Net N mineralization and immobilization were highest early in the incubation for 45 and 67Mgha-1 y-1 treatments. No significant differences in potential C and N mineralization between controls and soils amended at the lowest rate for 8 or 25 years suggests that biosolids applications at 22Mgha-1 y-1 are sustainable over the long-term. Higher potential N mineralization rates and soil nitrate concentrations under higher application rates may increase the risk of off-site nutrient transport and requires further evaluation.

Concomitant collection of air temperatures, humidities, insolation, and wind speeds, as well as water column temperatures were done so that heat fluxes could be computed using an energy budget method and Bowen ratio estimates. The empirical model that was found to correlate best with variations in malodorant concentrations and gradients above the lagoon had the terms describing evaporation from the lagoon surface and net available energy at the lagoon surface. Emissions were found to be much higher during the cool season than the warm season. This was despite much higher evaporation rates during the warm season. This could be explained by much lower lagoon concentrations of the malodorants in the warm season than in the cool season. Results of this work are being used to determine appropriate models to estimate malodorant emissions from lagoons and devise techniques for the abatement of nuisance emissions.

In the USA alone, excessive nutrients are blamed for nearly 5,700 impairments of surface water bodies. Innovative measures, such as maximizing drainage ditch nutrient retention, are being examined to decrease the amount of nitrogen (N) and phosphorus (P) running off agricultural lands and into aquatic receiving systems. The goal of this experiment was to measure the nutrient mitigation ability of six aquatic plants typically found in agricultural drainage ditches in the lower Mississippi River Basin. Experimental mesocosms (1.250.60.8 m) were filled with sediment and planted with monocultures of one of six obligate wetland plant species (Typha latifolia (broadleaf cattail), Panicum hemitomon (maidencane), Thalia dealbata (powdery alligator-flag), Echinodorus cordifolia (creeping burhead), Myriophyllum spicatum (Eurasian watermilfoil), and Saururus cernuus (lizard's tail)), while three replicates were left non-vegetated to serve as controls. Mesocosms were amended with 5 mgL super(-1) (each) of nitrate, ammonia, dissolved inorganic phosphorus, and total inorganic phosphorus, while nitrite amendments (1 mgL super(-1)) were also made over a 4-h hydraulic retention time. Following the 4-h exposure, "clean" (non-amended) water was flushed through mesocosms for an additional 8 h to assess residual leaching of nutrients. Outflow water concentrations and loads decreased for all examined forms of N and P. In certain cases, there were significant differences between plant species; however, for the majority, there was no statistical difference in percent decrease between plant species. While native aquatic vegetation shows promise for mitigation of nutrient runoff, further studies altering the hydraulic retention time for improved efficiency should be conducted.

A field plot was covered with ground cover fabric to prohibit plant growth and take advantage of the obligate symbiotic nature of AM fungi to selectively starve and remove them from the soil microbiological community. The decline in the AM fungus population was monitored through spore counts and most probable number bioassays. Response to inoculation experiments were conducted to contrast the response of Allium porrum L. to inoculation with in vitro produced spores of Glomus intraradices Schenck and Smith when plants were grown in the AM fungus-depleted soil vs. soil from an adjacent, cropped plot. Data indicated a strongly diminished, yet still viable population of AM fungi after 39 months of bare fallow. Plants grown in cropped soil showed no growth response nor increase in percentage root length colonized as a result of inoculation, while the response to inoculation of plants grown in the covered soil increased as the population of AM fungi declined below 1 propagule cm super(-3).

Dendroctonus ponderosae can be prevented from successfully colonizing and killing individual trees by ground-based sprays of insecticides applied directly to the tree bole. However, the future availability of several active ingredients, including carbaryl which is most commonly used in the western United States, is uncertain. Two novel insecticides, cyantraniliprole [Cyazypyr Delta TM-OD (oil dispersion) and Cyazypyr Delta TM-SC (suspension concentrate)] and chlorantraniliprole (Rynaxypyr registered ), and carbaryl were assayed in both filter paper and topical assays. RESULTS: Compared with 20 000 mg L-1 carbaryl (i.e. the maximum label rate for solutions applied to conifers for protection from bark beetle attack in the western United States), cyantraniliprole OD caused similar rates of mortality in D. ponderosae adults at 400-fold weaker concentrations in both bioassays, while cyantraniliprole SC caused similar rates of mortality at 40-fold weaker concentrations. Probit analyses confirmed that D. ponderosae is most sensitive to cyantraniliprole OD, while chlorantraniliprole was effective at concentrations similar to carbaryl. CONCLUSIONS: These results suggest that lower concentrations of carbaryl have merit for field testing than have been previously considered. While cyantraniliprole and chlorantraniliprole have similar modes of action, cyantraniliprole OD appears to have greater promise for protecting individual trees from mortality attributed to D. ponderosae attack and should be evaluated in field studies.

This study examined subsurface runoff in two hillslopes, one aspen dominated, the other conifer dominated, adjacent to a first order stream in snow-driven northern Utah. Snow accumulation, soil moisture, trenchflow and streamflow were examined in hillslopes and their adjacent stream. Snow water equivalents (SWEs) were greater under aspen stands compared to conifer, the difference increasing with higher annual precipitation. Semi-variograms of shallow spatial soil moisture patterns and transects of continuous soil moisture showed no increase in soil moisture downslope, suggesting the absence of subsurface flow in shallow (~12 cm) soil layers of either vegetation type. However, a clear threshold relationship between soil moisture and streamflow indicated hillslope-stream connectivity, deeper within the soil profile. Subsurface flow was detected at ~50 cm depth, which was sustained for longer in the conifer hillslope. Soil profiles under the two vegetation types varied, with deep aspen soils having greater water storage capacity than shallow rocky conifer soils. Though SWEs were less under the conifers, the soil profile had less water storage capacity and produced more subsurface lateral flow during the spring snowmelt.

RUSLE2's capabilities have been expanded over earlier versions using methods of estimating time-varying runoff and process-based sediment transport routines so that it can estimate sediment transport/deposition/delivery on complex hillslopes. In this report we propose and evaluate a method of predicting a series of representative runoff events whose sizes, durations, and timings are estimated from information already in the RUSLE2 database. The methods were derived from analysis of 30-year simulations using a widely accepted climate generator and runoff model and were validated against additional independent simulations not used in developing the index events, as well as against long-term measured monthly rainfall/runoff sets. Comparison of measured and RUSLE2-predicted monthly runoff suggested that the procedures outlined may underestimate plot-scale runoff during periods of the year with greater than average rainfall intensity, and a modification to improve predictions was developed. In order to illustrate the potential of coupling RUSLE2 with a process-based channel erosion model, the resulting set of representative storms was used as an input to the channel routines used in Chemicals, Runoff, and Erosion from Agricultural Management Systems (CREAMS) to calculate ephemeral gully erosion. The method was applied to a hypothetical 5-ha field cropped to cotton in Marshall County, MS, bisected by a potential ephemeral gully having channel slopes ranging from 0?5 to 5% and with hillslopes on both sides of the channel with 5% steepness and 22?1 m length. Results showed the representative storm sequence produced reasonable results in CREAMS indicating that ephemeral gully erosion may be of the same order of magnitude as sheet and rill erosion.

E. coli O157:H7 was induced to express Stx2 by culturing on solid agar media supplemented with 10-50 ng mL super(-1) of ciprofloxacin (CP). Bacterial cell lysates at each CP concentration were analyzed by MALDI-TOF-MS. A prominent ion at mass-to-charge (m/z) similar to 7820 was observed for the CP concentration range: 10-50 ng mL super(-1), reaching a maximum signal intensity at 20 ng mL super(-1). Complex MS/MS data were obtained of the ion at m/z similar to 7820 by post-source decay resulting in top-down proteomic identification as the mature, signal peptide-removed, disulfide-intact beta -Stx2. Eight fragment ion triplets (each spaced Delta m/z similar to 33 apart) were also observed resulting from backbone cleavage between the two cysteine residues (that form the intra-molecular disulfide bond) and symmetric and asymmetric cleavage of the disulfide bond. The middle fragment ion of each triplet, from symmetric disulfide bond cleavage, was matched to an in silico fragment ion formed from cleavage of the backbone at a site adjacent to an aspartic acid or glutamic acid residue. The flanking fragment ions of each triplet, from asymmetric disulfide bond cleavage, were not matched because their corresponding in silico fragment ions are not represented in the database. Easier to interpret MS/MS data were obtained for the disulfide-reduced beta -Stx2 which resulted in an improved top-down identification.

14522798 AB - a-[ordm We conducted an adaptive management experiment to monitor the effects of prescribed fire on an endemic mountainsnail in the dry forests of eastern Washington. a-[ordm Results showed that the burn prescriptions created a fine-scale mosaic of burn intensities, not significantly reducing mountainsnail densities. a-[ordm Carefully applied prescribed fire implemented under proper conditions is a valuable tool to restore dry forests and increase the resilience of habitat for mountain snails. The restoration of natural fire regimes has emerged as a primary management objective within fire-prone forests in the interior western US. However, this objective becomes contentious when perceived to be in conflict with the conservation of rare or endemic species. We monitored the effects of two forest restoration treatments, spring- vs fall-prescribed burning, on the density of the endemic Tiny Canyon mountainsnail (Oreohelix sp.). We used a randomized block design with three replicates of each of the treatments and controls, and analyzed our data using multivariate repeated measures analysis of variance. We conducted pre-treatment surveys for mountainsnails and post-treatment surveys at three time periods: within two weeks of the treatment, the next snail season following the treatment (next spring or fall), and one year following the treatments. We did not detect any statistically significant differences in mountainsnail densities as a result of the spring-burn or fall-burn treatments, time of survey, or treatmentA-time interaction. The burns resulted in a fine-scale mosaic that included un-burned and lightly burned areas that acted as refuge for mountainsnails. We recommend that the application of prescribed burning as a restoration treatment within mountainsnail habitat be conducted under prescriptions that create a mosaic of burn conditions, including small unburned areas, and that prescribed fire return intervals mimic natural fire intervals (10-40 years).

15049351 AB - Appropriate follow-up actions and decisions are needed when evaluating and interpreting clear positive results obtained in the in vitro assays used in the initial genotoxicity screening battery (i.e., the battery of tests generally required by regulatory authorities) to assist in overall risk-based decision making concerning the potential effects of human exposure to the agent under test. Over the past few years, the International Life Sciences Institute (ILSI) Health and Environmental Sciences Institute (HESI) Project Committee on the Relevance and Follow-up of Positive Results in In Vitro Genetic Toxicity (IVGT) Testing developed a decision process flow chart to be applied in case of clear positive results in vitro. It provides for a variety of different possibilities and allows flexibility in choosing follow-up action(s), depending on the results obtained in the initial battery of assays and available information. The intent of the Review Subgroup was not to provide a prescriptive testing strategy, but rather to reinforce the concept of weighing the totality of the evidence. The Review Subgroup of the IVGT committee highlighted the importance of properly analyzing the existing data, and considering potential confounding factors (e.g., possible interactions with the test systems, presence of impurities, irrelevant metabolism), and chemical modes of action when analyzing and interpreting positive results in the in vitro genotoxicity assays and determining appropriate follow-up testing. The Review Subgroup also examined the characteristics, strengths, and limitations of each of the existing in vitro and in vivo genotoxicity assays to determine their usefulness in any follow-up testing.

Flavour improvement might be achieved if fruits were harvested with some colour (to eliminate IG fruits) and/or stored at higher temperature with the ripening inhibitor 1-methylcyclopropene (1-MCP). RESULTS: 'Florida 47' tomatoes were harvested at GR (MG + IG), breaker (BR), turning (TR) and pink (PK) stages, treated (+) or not (-) with 1-MCP and stored at 13 and/or 18 degree C. 1-MCP treatment resulted in a gain of up to 6 days of shelf life depending on harvest maturity and storage temperature. Storage at 18 degree C rather than 13 degree C resulted in an increase in internal red colour, soluble solids (SS)/titratable acidity (TA) ratio and levels of many volatiles studied. The shelf life of BR (+) MCP fruits stored at 13 degree C was similar to that of MG fruits. IG fruits exhibited lowest levels of SS, TA and ten volatiles compared with BR fruits. CONCLUSION: Harvesting tomatoes with colour (BR), thereby eliminating IG fruits, and treating with 1-MCP resulted in better quality with adequate shelf life. Published 2011 by John Wiley & Sons, Ltd.

Cattle are maintenance hosts for serovar Hardjo, and development of vaccines that establish long-term protective immunity has been problematic; induction of high titers of anti-serovar Hardjo antibody does not appear to be protective. Rather, development of an antigen-specific Th1 response appears to be critical for limiting renal colonization and urinary shedding of bacteria. In this study we compared two monovalent killed bacterial cell vaccines to assess long-term (12 months) protection against live serovar Hardjo challenge. Although neither vaccine prevented infection, renal colonization and urinary shedding of bacteria were reduced compared to those of control animals. Increased proliferation of CD4+, CD8+, and T cells from vaccinated, but not control, animals was detected. In addition, NK cells from vaccinated animals and from all animals following infection, when exposed to antigen ex vivo, demonstrated a gamma interferon (IFN-) recall response. We propose that programming NK cells to respond quickly to L. borgpetersenii serovar Hardjo infection may be an important step toward developing protective immunity.

The toxicity of ozone (O sub(3)) gas at different relative humidities to control their conidia was determined. Conidia distributed on cover glasses were exposed to an atmosphere containing 200-350 mu L L super(-1) of O sub(3) gas at 35%, 75%, and 95% relative humidity (RH) at 25 degree C. O sub(3) gas was produced by UV light generators and passed through three 500 mL solutions of saturated MgCl sub(2) (35% RH), NaCl (75% RH), or K sub(2)SO sub(4) (95% RH). O sub(3) and RH inside the chamber were monitored. O sub(3) exposures were quantified as concentration x time products adjusted to 1 h ( mu L L super(-1) x h). After exposure to O sub(3) for varying periods, the conidia were removed from the chamber, placed on potato dextrose agar and their germination observed. Conidia died more rapidly at higher humidity than at lower humidity, and P. digitatum and P. italicum were more resistant to O sub(3) than B. cinerea. At 95% RH, 99% of the conidia of P. digitatum, P. italicum, and B. cinerea were incapable of germination after O sub(3) exposures of 817, 732, and 702 mu L L super(-1) x h, respectively. At 75% RH, similar inhibition required exposures of 1781, 1274, and 1262 mu L L super(-1) x h, respectively. At 35% RH, O sub(3) toxicity declined markedly, and 99% mortality required 11,410, 10,775, and 7713 mu L L super(-1) x h, respectively. These values can be used to select O sub(3) gas exposures needed to control these conidia. Conidia of B. cinerea were sprayed on to the surface of table grapes and 2 h later the grapes were exposed to 800-2000 mu L L super(-1) x h of O sub(3). O sub(3) at 800 mu L L super(-1) x h or more reduced the incidence of infected berries by 85% and 45% on 'Autumn Seedless' and 'Scarlet Royal' grapes, respectively. Fumigation with O sub(3) can control postharvest pathogenic fungi on commodities that tolerate this gas, or it can be applied to disinfect processing equipment and storage rooms when the produce is not present.

Feline immunodeficiency virus (FIV) and feline leukemia virus (FeLv) are related to human immunodeficiency virus and human leukemia virus, respectively, and these viruses are immunosuppressive. In the present study, the prevalence of antibodies to T. gondii, Bartonella spp., FIV, as well as FeLv and Dirofilaria immitis antigens was determined in sera from feral cats (Felis catus) from Cairo, Egypt. Using a modified agglutination test, antibodies to T. gondii were found in 172 (95.5%%) of the 180 cats with titers of 1aPGaPG5 in 9, 1aPGaPG10 in 9, 1aPGaPG20 in 3, 1aPGaPG40 in 5, 1aPGaPG80 in 5, 1aPGaPG160 in 15, 1aPGaPG320 in 22, and 1aPGaPG640 or higher in 104. Thus, 57.4%% had high T. gondii titers. Antibodies to Bartonella spp. were found in 105 (59.6%%) of 178, with titers of 1aPGaPG64 in 45, 1aPGaPG128 in 39, 1aPGaPG256 in 13, 1aPGaPG512 in 3, 1aPGaPG1,024 in 4, and 1aPGaPG2,048 in 1 cat. Antibodies to FIV were detected in 59 (33.9%%) of 174 cats. Of 174 cats tested, antigens to FeLv, and D. immitis were detected in 8 (4.6%%) and 6 (3.4%%) cats, respectively. The results indicate a high prevalence of T. gondii, Bartonella spp., and FIV infections in cats from Cairo, Egypt. This is the first report of Bartonella spp., and D. immitis infection in cats in Egypt.

The Willapa Bay oyster reserves were set aside in 1890 to preserve stocks of the native oyster Ostrea lurida in this estuary, but these stocks were overfished and replaced with the introduced Pacific oyster Crassostrea gigas during the late 1920s. Pacific oysters have spawned and set naturally in this estuary on a fairly regular basis since that time, and have formed the basis of a sustainable fishery established on state oyster reserves. The fishery is managed as an annual sale of oysters to private aquaculture interests. Oysters are harvested mostly by hand from intertidal tracts, usually moved to better growing areas closer to the estuary mouth, and shell is required to be returned to the reserves to perpetuate the fishery. Although oyster harvest for human consumption will remain an important social management goal, these bivalves have been shown to provide a suite of other ecosystem functions and services. A survey of the reserves suggests that they represent 11.2% of the intertidal habitat in Willapa Bay and cover substantial subtidal areas as well. A comparison with historical maps suggests that most of the low intertidal area in the reserves formerly populated by native oysters is now covered primarily with eelgrass (Zostera marina), which potentially serves as important habitat for numerous other organisms, including juvenile salmon, Dungeness crab, and migratory waterfowl like black Brant. Native oysters can still potentially be restored to some of these areas, but the value of both introduced oysters and eelgrass as habitat and ecosystem engineers also deserves attention, and the reserves provide an excellent place to elucidate the role of these additional conservation targets at the landscape scale.

Plant volatiles included ethyl (E,Z)-2,4-decadienoate (pear ester), (E)-I2I2-farnesene, (Z)-3-hexenyl acetate, A-A- farnesol, and (E)-4,8-dimethyl-l,3,7-nonatriene (DMNT). Male codling moth exhibited upwind behavioral responses to each compound in flight tunnel tests with acetic acid > DMNT > A-A- farnesol > (Z)-3-hexenyl acetate > pear ester > (E)-I2I2-farnesene. In apple orchards, however, only pear ester was an effective lure when used alone with clear pane traps. Choice tests in a flight tunnel with delta traps baited with DMNT plus acetic acid caught significantly more male and females than unbaited traps and significantly more females than DMNT-baited traps. Combining pear ester or DMNT loaded in septa lures with separate vials containing acetic acid significantly increased both male and female moth catch compared with the plant volatile alone, acetic acid alone, and unbaited pane traps in field trials. Similar results were not obtained with the other three plant volatiles. Septum loadings of 1 and 10 mg with either pear ester or DMNT in combination with acetic acid caught similar numbers of moths in orange delta traps. Sixty to 75% of the moths captured in traps baited with DMNT plus acetic acid were females. Moth catches in traps baited with DMNT plus acetic acid were aa40% of catches in similar traps baited with pear ester plus acetic acid.

Thus, this 5-yr study was conducted to determine parasitism and predation of sentinel and natural occurring Euschistus servus (Say) and Nezara viridula (L.) egg masses in farmscapes in Georgia. A variety of parasitoids including six scelionids, Trissolcus basalis (Wollaston), T. brochymenae (Ashmead), T. euschisti (Ashmead), T. thyantae Ashmead, Telenomus podisi Ashmead, and Gyron obesum Masner, and one encyrtid, Ooencyrtus spp., was recovered from E. servus and N. viridula eggs, but overall the greatest diversity of parasitoids emerged from stink bug eggs in corn. Only T. basalis and T. podisi parasitized both N. viridula and E. servus eggs in all three crops over all farmscapes. A wide variety of predators, including Orius insidiosus (Say), Geocoris punctipes (Say), G. uliginosus (Say), Coccinella septempunctata (L.), Hippodamia convergens Guerin-Meneville, Harmonia axyridis (Pallas), Coleomegilla maculata (De Geer), Scymnus loewii Mulsant, Scymnus ardelio Horn, and Solenopsis invicta Buren, preyed on stink bug eggs in each crop. When differences were detected, generally percent parasitization per egg mass was higher than predation in corn, and percent predation was higher than parasitization in peanut. Overall, percent predation per egg mass was higher than parasitization in cotton, but on one occasion percent parasitization was higher than predation in cotton associated with corn. Seasonal occurrence and abundance of natural enemies, levels of parasitization and predation of stink bug eggs, and percent egg predation by sucking and chewing predators indicated that natural enemies of stink bug eggs disperses from crop to crop in the farmscapes. Stink bug egg predators and parasitoids are likely responding to host plant switching by their prey or hosts. In conclusion, this study has shown that natural enemies of stink bugs are prevalent and important biological control agents in these farmscapes.

Levels of Lygus-induced damage to cotton can vary by Lygus ages or gender, and these variations complicate interpretation of studies designed to elucidate Lygus and cotton interactions. Variations in observed injury may reflect different behaviors among Lygus gender or ages. We compared times allocated to feeding and trivial movement between male and female adult L. hesperus of different reproductive states: prereproductive, reproductive and mated, and reproductive and unmated. Prereproductive adults exhibited less trivial movement and spent more time stylet-probing compared with reproductive unmated and mated adults. Mated females stylet-probed more times than other classes of adults, whereas mated and unmated reproductive females exhibited more test probes ( greater than or equal to 10 s duration) than prereproductive females. Reproductive females probed the anther region of squares less than prereproductive females. Instead, reproductive females tended to stylet-probe squares below the bracts, which is also where they oviposited. Each oviposition event was preceded by a short duration stylet-probe at the oviposition location. Unmated reproductive males exhibited more test probes but fewer ingestion probes (>1 min) compared with prereproductive and mated males. These results indicate a pattern in which prereproductive adults are less active and feed more compared with reproductive adults, but behaviors vary among reproductive adults of different gender and mating states. We propose that differences in behaviors exhibited among adult L. hesperus are related to the different requirements imposed by mate seeking, mate attraction, and oviposition.

This study reports the results of field releases and recovery of P. humilis in California, and laboratory investigations to determine the effects of food provision, high temperature, and insecticidal bait spray on the parasitoid's survival and fecundity. Parasitoids (3,613-7,823) were released in Orland, San Juan Bautista, Cayucos, Sylmar, Santa Barbara, and San Diego during October through December 2006. Mean daily temperatures at the release sites ranged from 10.7 degree C in Orland to 20.9 degree C in San Juan Bautista. The lowest (0.5) and highest (29.7) mean number of adult B. oleae per day per trap was captured in Orland and Sylmar, while the lowest (0.01) and highest (2.21) number of third instar larvae per fruit was collected on 11 December in Orland and on 5 October in San Diego in prerelease samples, respectively. Parasitoids were recovered from all release sites, the lowest (0.3%) and highest (100%) parasitism occurred on 25 January in Sylmar and on 26 October in Cayucos, respectively. At 24 degree C, parasitoids reared from B. oleae larvae survived 36 d on honey, 31 d on orange juice, and 28 d on honeydew, which was significantly longer than on cut olive fruit (8 d) or without food (11 d), but was similar to those reared from C. capitata larvae under the same food conditions. Under a high diurnal temperature regime (18.3-35 degree C) reflecting the summer olive growing conditions in the California Central Valley, the parasitoids survived <5 d when no food or only water was provided. Its longevity and life-time fecundity significantly increased by provision of honey or honeydew. There was no difference in the parasitoid's longevity between females and males or between food and sexes. Percent mortality of parasitoid adults was not significantly affected by the exposure to insecticidal fruit fly bait (GF-120) in four different types of choice tests with artificial honeydew and GF-120.

In arthropods, these maternally transmitted bacteria often induce a variety of phenotypic effects to enhance their own spread within host populations. Wolbachia phenotypic effects generally either provide benefits to infected host females (cytoplasmic incompatibility, positive fitness effects) or bias host sex ratio in favor of females (male-killing, parthenogenesis, feminization), all of which increase the relative production of infected females in host populations. Wolbachia surveys have found infections to be exceedingly common in ants, but little is known at this juncture as to what phenotypic effects, if any, they induce in this group. Previous studies have demonstrated that individuals from native populations of the invasive fire ant Solenopsis invicta commonly harbor one or more of three Wolbachia variants. One of the variants, wSinvictaA, typically occurs at low prevalence in S. invicta populations, appears to have been transmitted horizontally into S. invicta three or more times, and has been lost repeatedly from host lineages over time. In order to determine the phenotypic effects and likely population dynamics of wSinvictaA infections in these ants, brood production patterns of newly mated fire ant queens were studied during simulated claustral founding and measured wSinvictaA transmission fidelity within mature single-queen families. No clear evidence was found for Wolbachia-mduced cytoplasmic incompatibility, significant fitness effects, or male-killing. Maternal transmission was perfect to both virgin queens and males. Possible mechanisms for how this variant could be maintained in host populations are discussed.

The substrate at these sites, consisting of waste hay mixed with bovine manure and urine, provided an excellent developmental habitat for immature stable flies. Stable flies were the most frequently collected fly emerging from these sites with a yearly average of 1,581 emerging per square meter. Stable fly emergence from these sites began in early May (235 annual accumulated Day-Degree 10 degree C [DD10]), peaked in late June and early July (400-900 DD10) and then dropped to very low levels in late July (>900 DD10). The temporal pattern of stable fly emergence from the hay feeding sites differed from that of adult populations measured with sticky traps. Adult populations increased in the spring before significant emergence from the hay feeding sites was observed, dipped in midsummer soon after the hay feeding sites became nonproductive, and then rebounded in the late summer when emergence from the hay feeding sites was very low. The drop in productivity of the hay feeding sites appeared to be because of endogenous factors associated with decomposition of the substrate rather than temperature or precipitation. Winter hay feeding sites appear to be primary sources of stable flies during the early summer, however, they are not responsible for late summer and fall stable fly populations. Overall, the inner most 2-m annulus of the hay feeding sites was the most productive, however, spatial variation among sites was observed. The sex ratio of emerging flies did not differ from 1:1 and the temporal pattern of emergence was similar for males and females. Although several other species of flies were collected emerging from the hay feeding site substrate, house flies (Musca domestica L.) were notably absent.

To determine the cause of variation and to refine the criteria used to define diapause status, we obtained eggs from adults collected from the field and from long-term laboratory colonies. Concurrent experiments were conducted at two locations. L. hesperus were reared from egg to adulthood under photophases of either 10 or 14 h and at a constant temperature (26.6 degree C, Shafter, CA; 27.5 degree C, Maricopa, AZ). Adults were dissected at 10-d posteclosion to measure diapause status using both stringent and relaxed morphological criteria. Under both sets of criteria, offspring of field caught parents were more likely to enter diapause with short day exposure than those offspring from stock colonies. The relaxed criteria appeared appropriate for distinguishing diapause in males, whose reproductive organs can appear undeveloped after mating, although the stringent criteria appeared appropriate for females. Additional analyses were conducted to determine whether extended laboratory rearing influenced other behavioral or physiological traits. Bugs from stock colonies were more likely to mate, and to oviposit as virgins, than were bugs originating from the field. The results demonstrate a pronounced effect of colony rearing on L. hesperus physiology and behavior, and also have led to refinement of the criteria used to assess diapause status.

States have kept county-level records on the locations of beetle outbreaks for the past 50 yr. This study determined how accurately patterns of county-level infestations in preceding years could predict infestation o ccurrence in the current year and if there were emergent patterns that correlated strongly with beetle outbreaks. A variety of methods were tested as infestation predictors, including quantification of either the exact locations of infested grid cells during one or two preceding years, or the neighborhood infestation intensity (number of infested cells in a neighborhood) in these years. The methods had similar predictive abilities, but the simpler methods performed somewhat better than the more complex ones. The factors most correlated with infestations in future years were infestation in the current year and the number of surrounding counties that were infested. Infestation history helped to predict the probability of future infestations in a region, but county-level patterns alone left much of the year-to-year variability unexplained.

Thus, it could be useful as a fumigant to decontaminate honey comb between uses. The experiments here are intended to determine the exposure levels required to kill an insect pest and spore forming bee pathogens. Ozone was effective against greater wax moth, Galleria mellonella (L.) (Lepidoptera: Pyralidae), even on naturally infested comb. Neonates and adults were the easiest life stages to kill, requiring only a few hours of exposure, whereas eggs required a 48-h exposure (at 460-920 mg O3/m3). Two honey bee, Apis mellifera L. (Hymenoptera: Apidae), pathogens, Ascosphaera apis (a fungus that causes chalkbrood) and Paenibacillus larvae (a bacterium that causes American foulbrood), also were killed with ozone. These pathogens required much higher concentrations (3,200 and 8,560 mg O3/m3, respectively) and longer exposure periods (3 d) than needed to control the insects. P. larvae was effectively sterilized only when these conditions were combined with high temperature (50 degree C) and humidity ( greater than or equal to 75% RH). Thus, ozone shows potential as a fumigant for bee nesting materials, but further research is needed to evaluate its acceptability and efficacy in the field. The need for a reliable method to decontaminate honey bee nesting materials as part of an overall bee health management system is discussed.

Valine (Val) is considered the 4th limiting amino acid for broilers fed on diets containing ingredients from vegetable origin. However, Val and Isoleucine (Ile) may be co-limiting for broilers fed on diets containing animal protein meals. An experiment was conducted to examine growth responses and meat yield of broilers provided diets varying in digestible Val (dVal) and digestible Ile (dIle) concentrations from 28 to 42 d of age. 2. Eight experimental diets varying in dVal (dVal to dLys ratios from 0.66 to 0.76) and dIle (dIle to dLys ratios from 0.57 to 0.67) were studied; digestible Lysine (Lys) was formulated to 9.9 g/kg in all diets. 3. Broilers fed on a negative control (NC) diet supplemented with crystalline Val (L-Val) and crystalline Ile (L-Ile), dVal to dLys = 0.76 and dIle to dLys = 0.67, grew faster and had higher breast meat yield than birds fed on NC + L-Ile (dVal to dLys = 0.66 and dIle to dLys = 0.67), NC + L-Val (dVal to dLys = 0.76 and dIle to dLys = 0.57), and NC + reduced L-Val and L-Ile (dVal to dLys = 0.71 and dIle to dLys = 0.62). 4. Feeding broilers on the NC + L-Val and L-Ile (dVal to dLys = 0.76 and dIle to dLys = 0.67) diets gave similar BW gain, carcase weight and yield and total breast meat weight and yield to birds fed on the positive control-fed broilers with no added L-Val and L-Ile (dVal to dLys = 0.76 and dIle to dLys = 0.67). 5. These results indicate that Val and Ile are co-limiting in diets containing poultry by-product meal.

The effectiveness of imazapic herbicide in reducing downy brome cover has been variable, and there is uncertainty about the impacts of imazapic on native species. We used a before-after-control-impact (BACI) field experiment and greenhouse studies to (1) determine if imazapic herbicide applied at 132 g ai ha1 (8 oz/ac1) and seeding with two native shrub species (Wyoming big sagebrush [Artemisia tridentata] and Mexican cliffrose [Purshia mexicana]) reduced downy brome cover and promoted shrub establishment, (2) assess potential effects of imazapic on nontarget plant species and plant community composition, and (3) determine if imazapic affected downy brome or seeded shrub species when applied at different developmental stages. Seeding shrubs, alone, or in combination with imazapic application, did not significantly increase shrub density, possibly because of droughty conditions. In the field, imazapic reduced downy brome cover by 20% and nontarget forb cover by 25% and altered plant community composition the first year after treatment. Imazapic was lethal to downy brome at all growth stages in the greenhouse and reduced shrub germination by 50 to 80%, but older shrub seedlings were more tolerant of the herbicide. We conclude that a one-time application of imazapic combined with seeding shrubs was only slightly effective in rehabilitating areas with high downy brome and thatch cover and resulted in short-term impacts to nontarget species. These results highlight the need to treat downy brome infestations before they become too large. Also, removing thatch prior to treating with imazapic, although likely lethal to the native shrubs we studied, could increase the effectiveness of imazapic.

The species are becoming increasingly abundant in the northeastern United States and southeastern Canada and are difficult to manage. However, we know little about the demographic parameters of these species. We determined the survival, annual rate of vegetative growth, and fecundity of mature clumps of these swallowwort species. We selected four PSW sites (three of which comprised both old-field and forest habitats) in central New York and three BSW old fields in southeastern New York. BSW is largely restricted to higher light habitats in its introduced range. In each habitat, we followed the growth of 30 to 32 randomly selected clumps of similar size (2 to 5 stems clump1 in the initial year) for 3 to 4 yr. Yearly survival was 99.6 - 0.3% [mean - standard error] for PSW and 100 - 0% for BSW. In old fields, vegetative expansion varied from 0.01 - 0.1 to 4.6 - 0.4 stems clump1 yr1 for BSW and 0.02 - 0.2 to 2.1 - 0.5 stems clump1 yr1 for PSW. In forests, PSW growth was lower with vegetative expansion ranging from 0.01 - 0.1 to 0.8 - 0.2 stems clump1 yr1. Fecundity of PSW in 2007 and 2008 (130 - 10 viable seeds stem1 yr1) was similar to BSW (100 - 10 viable seeds stem1 yr1). Fecundity of PSW in forests was generally lower than PSW in old fields, but it varied greatly among sites (0 to 170 viable seeds stem1 yr1). We found that stem growth and fecundity did not vary with clump size (stems per clump). Since vegetative expansion and fecundity rates were high in old-field habitats, but were generally low or nonexistent in forest habitats, we suggest that management of these two invasive vines be focused in higher light environments to reduce overall seed production and its subsequent spread to surrounding areas.

Weekly inundative releases of a coccinellid predator (Coccinella undecimpunctata L. [Coleoptera: Coccinellidae]), a common green lacewing predator (Chrysoperla carnea Stephen [Neuroptera: Chrysopidae]), and a mirid predator (Macrolophus caliginosus[Wagner][Hemiptera: Miridae]) were independently made in three vegetable crops (cabbage [Brassica oleracea var. capitata L.], cucumber [Cucumis sativus L.], and squash [Cucurbita pepo L.]) for the management of the sweetpotato whitefly. Approximately 1 million to 2.5 million larvae or nymphs of each predator were released in the vegetable crops during 20 weeks. Whitefly populations were reduced by approximately 25%-45% during most of the season in each crop where each predator was released. The effect of each predator was similar on whitefly population reduction. Late in the season (October) when whitefly populations were low, generally no benefit was obtained from releasing the predators. Numbers of predators recovered during sampling in all crops were greatest for C. carnea, but this corresponded with the fact that more individuals of this predator were released than any other predator in the experiment. These results help define the utility of these natural enemies for managing B. tabaci in vegetable crops.

With the current emphasis on the role of carbon in the environment, agricultural systems and their impacts on the carbon cycle are important parts of the overall issue. Organic carbon lost to streams and rivers can promote bacterial production and microbial respiration of CO2 to the atmosphere. Although pastures and grasslands are major land uses in the humid U.S., row crop agriculture has received most of the carbon research focus. The objective of this study at the North Appalachian Experimental Watershed near Coshocton, Ohio, was to assess organic carbon transported from a pasture system, particularly on a runoff event basis. A beef cowacalf herd rotationally grazed a paddock during the growing season and was fed hay in this paddock during the dormant season (NovemberaApril). Surface runoff and sediment loss was measured and sampled throughout the year from the small watershed in the paddock. Most of the sediment samples were collected during the dormant season. With continuous winter occupancy, the percent vegetative cover was often aO50% in the late winter/early spring, which increased the potential for soil loss. During the 10-year period of sample collection, there were 376 runoff events and 115 events with sediment loss aY10kghaa1 from the watershed in the winter feeding area. The largest 6 events carried nearly 50% of the total sediment and sediment-attached C lost during this period. Annual losses of sediment and sediment-C varied considerably but averaged 2642 and 140kghaa1, respectively. There was no significant correlation between the amount of sediment transported during individual events and the C concentration on the associated sediment. The pasture sediments have a C enrichment ratio of 1.2a1.5 compared with the 0a2.5cm soil layer. Pasture sediment-C concentrations were >2x the C concentrations on sediments from nearby row crop watersheds.

The Hypocreales, Beauveria bassiana (Balsamo) Vuillemin, Metarhizium anisopliae (Metschnikoff), and Isaria fumosorosea Wize, were tested for efficacy against D. maculatus larvae on concrete, plastic, leather, and wood surfaces. Only wood had a significant negative effect on efficacy, and B. bassiana was the most efficacious species. The conidia of all three species lost viability quickly on wood with various responses on the other surfaces. When beetle larvae were exposed to deposited B. bassiana and incubated at 43, 56, 75, or 82% relative humidity, mortality was greatest at the lowest humidity suggesting enhancement of fungal infection by desiccation stress. The results indicate that entomopathogenic Hypocreales, especially B. bassiana, may be useful for control of hide beetles when applied at a low dose to surfaces that do not impact the viability of conidia.

The objective of this study was to determine the effectiveness of gallium maltolate (GaM) against Salmonella in vitro and to determine whether oral administration of GaM would reduce fecal shedding of Salmonella in cattle. Gallium is a semimetal exhibiting antimicrobial properties against some pathogenic bacteria, including Salmonella, by exploiting their need for iron to survive and replicate. In vitro growth studies were performed in pure cultures of Salmonella and in mixed cultures from ruminal fluid. Inclusion of GaM in culture medium or in mixed cultures of ruminal fluid resulted in a significant reduction in growth of Salmonella, suggesting that GaM may be effective for limiting growth and survival in vivo. Therefore, we subsequently administered two doses of GaM to Holstein steers, experimentally infected them with Salmonella, and quantitatively and qualitatively monitored fecal shedding at 12-h intervals. Sixty hours after beginning treatment, cattle were euthanized, and luminal contents and tissue were aseptically harvested from the rumen, jejunum, spiral colon, cecum, and rectum. The luminal contents were processed for quantitative and qualitative analysis of the challenge strains of Salmonella, and tissue samples were enriched and plated for qualitative analysis. We found no significant differences between control and treated animals in quantitative levels of Salmonella in the feces or the luminal contents. Likewise, we observed no pattern between control and treated animals in the frequency of positive or negative results from enriched feces, luminal contents, or tissue samples. These results suggest that GaM was not effective for reducing Salmonella in cattle.

The objective of this study was to determine the suitability of using gelatin gels as reference materials for performance testing of texture measurement systems. Three replications of 5 gels (15%, 20%, 25%, 30%, and 35% gelatin) were prepared, vacuum packaged, and stored at 4 degree C until use. Three randomly selected strips from each gel were subjected to WBSF testing on 4 instruments (A, B, C, or D) on days 1 and 8. Additional strips from each gel were subjected to WBSF testing on instruments A and C on day 29. Regression line estimates for each set of gels were analyzed. Gel WBSF values ranged from 10 to 177 N. The WBSF by gel concentration response was highly linear (P 0.05) by length of gel storage (1, 8, and 29 d). Data from this study suggest that gelatin gels can be used for evaluating WBSF values from various instruments and for validating the performance of meat shear force testing. Practical Application: Validating the performance of meat shear force testing is vital to establishing meat tenderness standards. The gelatin gel standards developed in this study exhibited a highly linear, repeatable relationship with shear force and were found to be stable for at least a month. These gel standards would provide a tool for the meat industry to harmonize shear force measurements across laboratories and various texture measuring instruments.

Golden Delicious apples were spot inoculated withE. coliO157:H7 orS. Stanley and spray coated with PLA solutions containing lactic acid (LA), disodium ethylenediaminetetraacetic acid (EDTA), sodium benzoate (SB), potassium sorbate (PS), or their combination (LA + EDTA, SB + LA, SB + LA + EDTA). Apples without any coating treatment served as controls. Coating treatments were allowed to dry fully, and the apples were stored at 4 degree C for 14 d. Antimicrobial coatings reduced populations ofE. coliO157:H7 andS.Stanley by up to 4 log CFU/cm2 at 1 d and 4.7 log CFU/cm2 at 14 d, compared to controls. SB + LA combination had a similar effectiveness as the SB + LA + EDTA combination against both pathogens and was more effective than other coating treatments. Without antimicrobial treatment,E. coliO157:H7 andS.Stanley were able to survive on apples stored at 4 degree C for up to 14 d. The antimicrobial PLA coating provides an alternative intervention to reduce the pathogens on apples. Practical Application: Antimicrobial PLA coatings provide an alternative method to reduce pathogenic contaminations on fruit surface, and therefore, reduce the risk of food-borne outbreaks.

The model was validated using 2 (5 to 15 degree C; 600 h and 10 to 40 degree C; 52 h) sinusoidal, continuously varying temperature profiles. LWE adjusted to pH 7.8 was inoculated with approximately 2.5-3.0 log CFU/mL ofSalmonellaspp., and the growth data at several isothermal conditions (5, 7, 10, 15, 20, 25, 30, 35, 37, 39, 41, 43, 45, and 47 degree C) was collected. A primary model (Baranyi model) was fitted for each temperature growth data and corresponding maximum growth rates were estimated. Pseudo-R2 values were greater than 0.97 for primary models. Modified Ratkowsky model was used to fit the secondary model. The pseudo-R2 and root mean square error were 0.99 and 0.06 log CFU/mL, respectively, for the secondary model. A dynamic model for the prediction ofSalmonellaspp. growth under varying temperature conditions was developed using 4th-order Runge-Kutta method. The developed dynamic model was validated for 2 sinusoidal temperature profiles, 5 to 15 degree C (for 600 h) and 10 to 40 degree C (for 52 h) with corresponding root mean squared error values of 0.28 and 0.23 log CFU/mL, respectively, between predicted and observedSalmonellaspp. populations. The developed dynamic model can be used to predict the growth ofSalmonellaspp. in LWE under varying temperature conditions. Practical Application: Liquid egg and egg products are widely used in food processing and in restaurant operations. These products can be contaminated withSalmonellaspp. during breaking and other unit operations during processing. The raw, liquid egg products are stored under refrigeration prior to pasteurization. However, process deviations can occur such as refrigeration failure, leading to temperature fluctuations above the required temperatures as specified in the critical limits within hazard analysis and critical control point plans for the operations. The processors are required to evaluate the potential growth ofSalmonellaspp. in such products before the product can be used, or further processed. Dynamic predictive models are excellent tools for regulators as well as the processing plant personnel to evaluate the microbiological safety of the product under such conditions.

Many strains are now becoming multidrug resistant. Apple-based edible films containing carvacrol and cinnamaldehyde were evaluated for bactericidal activity against antibiotic resistant and susceptibleC. jejunistrains on chicken. Retail chicken breast samples inoculated with D28a and H2a (resistant strains) and A24a (a sensitive strain) were wrapped in apple films containing cinnamaldehyde or carvacrol at 0.5%, 1.5%, and 3% concentrations, and then incubated at 4 or 23 degree C for 72 h. Immediately after wrapping and at 72 h, samples were plated for enumeration of viableC. jejuni. The antimicrobial films exhibited dose- and temperature-dependent bactericidal activity against all strains. Films with greater than or equal to 1.5% cinnamaldehyde reduced populations of all strains to below detection at 23 degree C at 72 h. At 4 degree C with cinnamaldehyde, reductions were variable for all strains, ranging from 0.2 to 2.5 logs and 1.8 to 6.0 logs at 1.5% and 3.0%, respectively. Films with 3% carvacrol reduced populations of A24a and H2a to below detection, and D28a by 2.4 logs at 23 degree C and 72 h. A 0.5-log reduction was observed for both A24a and D28a, and 0.9 logs for H2a at 4 degree C at 3% carvacrol. Reductions ranged from 1.1 to 1.9 logs and 0.4 to 1.2 logs with 1.5% and 0.5% carvacrol at 23 degree C, respectively. The films with cinnamaldehyde were more effective than carvacrol films. Reductions at 23 degree C were greater than those at 4 degree C. Our results showed that antimicrobial apple films have the potential to reduceC. jejunion chicken and therefore, the risk of campylobacteriosis. Possible mechanisms of antimicrobial effects are discussed. Practical Application: Apple antimicrobial films could potentially be used in retail food packaging to reduceC. jejunicommonly present on food.

The strain FBR5 was chosen because of its ability to ferment both hexose and pentose sugars under semi-anaerobic conditions without using antibiotics. The average ethanol produced from the available sugars (21.9a47.8ANBg/L) ranged from 8.8 to 17.3ANBg/L (0.28a0.45ANBg/g available sugars, 0.31a0.48ANBg/g sugar consumed) with ethanol productivity of 0.27a0.78ANBgl super(a1)ANBh super(a1) in a set of 14 continuous culture (CC) runs (16a105ANBdays). During these CC runs, no loss of ethanol productivity was observed. This is the first report on the continuous production of ethanol by the recombinant bacterium from a lignocellulosic hydrolysate.

We have identified the genes and associated metabolic pathways involved in the water-deficit stress response in leaf and root. Gene expression profiles were developed for leaf and root tissues subjected to slow-onset water deficit under controlled, glasshouse conditions. The water-deficit stress was characterized by leaf water potential of a23.1 bars for stressed tissue compared to a8.7 bars for fully-irrigated control plants and a corresponding decrease in net carbon assimilation to approximately 60% of the rates seen in the irrigated controls (30.3 plus or minus 4.7 mu mol CO sub(2) m super(a 2) s super(a1) compared to 17.8 plus or minus B5.9 mu mol CO sub(2) m super(a 2) s super(a1)). Profiling experiments revealed 2,106 stress-responsive transcripts, 879 classified as stress-induced, 1,163 stress-repressed, and 64 showed reciprocal expression patterns in root and leaf. The majority of stress-responsive transcripts had tissue-specific expression patterns and only 173 genes showed similar patterns of stress responsive expression in both tissues. A variety of putative metabolic and regulatory pathways were identified using MapMan software and the potential targets for candidate gene selection and ectopic expression to alter these pathways and responses are discussed.

Riparian buffer practices are also considered in this synthesis due to their implementation in wetlands or effects on wetland ecosystem service provisioning when implemented adjacent to wetlands. Conservation practices are most extensive in the first three of the following seven regions analyzed: Mississippi Alluvial Valley, Glaciated Interior Plains, Piedmont-Coastal Plain, Prairie Pothole Region, California Central Valley, Appalachia, and the High Plains. Of the eight dominant practices available to establish and manage wetlands, the three most prevalent are Wetland Establishment, Wetland Management, and Riparian Buffer establishment and management. Differences in physiography among regions strongly influence the types of practices commonly applied. Highly altered drainage patterns and nutrient loading common to agriculture can make wetland establishment difficult. Nutrient enrichment, especially with nitrogen, can create trade-offs between reduced export of nutrients downstream (e.g., nitrate) and enhanced greenhouse gas emissions (e.g., nitrous oxide). Guidance is needed that considers the full array of ecosystem functions and services of multiple practices across a range of spatial scales. Both positive and negative effects need to be addressed given the trade-offs between enhancement of ecosystem services and the lack of knowledge of thresholds at which ecosystem functions are no longer ecologically or economically sustainable. In many cases, data are not presently available, nor is there a suitable monitoring process in place to assess the long-term effects of agriculture on additional wetlands and the potential services they provide, and vice versa. This points to the need to better match practices with goals, to evaluate restoration costs and benefits, and to optimize how decision-making is distributed between national and local levels.

Farm Bill conservation practices that restore or enhance wetlands can return their ecological functions and services to the agricultural landscape. We review the extent of regional knowledge regarding the effectiveness of these conservation practices. Riparian buffers and wetland habitat management have been the most commonly applied wetland-related practices across the region. Riparian Forest Buffers (RFB) have been most studied as a practice. Water quality functions including pollutant removal, provision of aquatic habitat, and enhanced instream chemical processing have been documented from either installed RFBs or natural riparian forests; forest buffers also serve wildlife habitat functions that depend in part on buffer width and connectivity. Wetland restoration/creation and habitat management practices have been less studied on regional agricultural lands; however, research on mitigation wetlands suggests that functional hydrology, vegetation, and faunal communities can be restored in depressional wetlands, and the wetland habitat management practices represent techniques adapted from those used successfully on wildlife refuges. Other conservation practices can also support wetland services. Drainage management on converted wetland fiats restores some water storage functions, and viable wetlands can persist within grazed fiats if livestock access and grazing are managed appropriately. Because wetland hydrogeomorphic type influences functions, ecosystem services from conservation wetlands will depend on the specifics of how practices are implemented. In a region of diverse wetlands, evaluation of ecological benefits could be improved with more information on the wetland types restored, created, and managed.

These agencies generally have regulatory authority over the production and retail sectors of the farm-to-table continuum. Any predicted change in contamination that results from new policy that regulates production practices occurs many steps prior to consumption of the product. This study proposes a framework for conducting microbial food-safety risk assessments; this framework can be used to quantitatively assess the annual effects of national regulatory policies. Advantages of the framework are that estimates of human illnesses are consistent with national disease surveillance data (which are usually summarized on an annual basis) and some of the modeling steps that occur between production and consumption can be collapsed or eliminated. The framework leads to probabilistic models that include uncertainty and variability in critical input parameters; these models can be solved using a number of different Bayesian methods. The Bayesian synthesis method performs well for this application and generates posterior distributions of parameters that are relevant to assessing the effect of implementing a new policy. An example, based on Campylobacter and chicken, estimates the annual number of illnesses avoided by a hypothetical policy; this output could be used to assess the economic benefits of a new policy. Empirical validation of the policy effect is also examined by estimating the annual change in the numbers of illnesses observed via disease surveillance systems.

The 45 proteins share the conserved beta -barrel and plug domains of TonB-dependent proteins but only 18 of them have an N-terminal signaling domain characteristic of TonB-dependent transducers (TBDTs), which participate in cell-surface signaling systems. Phylogenetic analyses of the 18 TBDTs and 27 TonB-dependent receptors (TBDRs), which lack the N-terminal signaling domain, suggest a complex evolutionary history including horizontal transfer among different microbial lineages. Putative functions were assigned to certain TBDRs and TBDTs in clades including well-characterized orthologs from other Pseudomonas spp. A mutant of Pf-5 with deletions in pyoverdine and enantio-pyochelin biosynthesis genes was constructed and characterized for iron-limited growth and utilization of a spectrum of siderophores. The mutant could utilize as iron sources a large number of pyoverdines with diverse structures as well as ferric citrate, heme, and the siderophores ferrichrome, ferrioxamine B, enterobactin, and aerobactin. The diversity and complexity of the TBDTs and TBDRs with roles in iron uptake clearly indicate the importance of iron in the fitness and survival of Pf-5 in the environment.

The equivalent chain lengths (ECL) of all 220 C4-C23 monomethyl branched FAME on OV-1 stationary phase were measured, achieving an average repeatability of +/-0.0004 ECL units. The monomethyl branched FAME was identified by GC on the basis of regularity of the fractional chain lengths (FCL) dependence on the number of carbon atoms (C sub(z) of individual homologous series of methyl 2-, 3-, ..., 21-FAME. The prediction of retention of the first homologues, having the new position of methyl group beginning at higher carbon atoms number, and analogously for the second, third, fourth, and other members of the homologous series, allowed the dependence FCL = f(C) sub(z)) for the first and subsequent members of beginning homologous of monomethyl derivatives of FAME. The identification was confirmed by mass spectrometry. All of the methyl isomers of FAME, which could not be completely separated by gas chromatography due to having a methyl group in surroundings of the middle of the carbon chain, were resolved by mass spectrometry using deconvolution in a SIM-mode. Measured gas chromatographic and mass spectrometric data were applied for identification of the monomethyl branched saturated FAME in tongue coating.

A mild heat shock (HS) pretreatment (30min at 40 degree C) improved the tolerance of M. fructicola to subsequent high temperature (45 degree C, 20-30min) and oxidative stress (0.4molL-1 hydrogen peroxide, 20-60min). HS-treated yeast cells showed less accumulation of reactive oxygen species (ROS) than nontreated cells in response to both stresses. Additionally, HS-treated yeast exhibited significantly greater (P<0.0001) biocontrol activity against Penicillium expansum and a significantly faster (P<0.0001) growth rate in wounds of apple fruits stored at 25 degree C compared with the performance of untreated yeast cells. Transcription of a trehalose-6-phosphate synthase gene (TPS1) was upregulated in response to HS and trehalose content also increased. Results indicate that the higher levels of trehalose induced by the HS may contribute to an improvement in ROS scavenging, stress tolerance, population growth in apple wounds and biocontrol activity of M. fructicola.

However, fungi that cause brown rot of wood, a major route for biomass recycling in coniferous forests, utilize wood polysaccharides efficiently while removing little of the lignin. The mechanism by which these basidiomycetes breach the lignin remains unclear. We used recently developed methods for solubilization and multidimensional 1H-13C solution-state NMR spectroscopy of ball-milled lignocellulose to analyse aspen wood degraded by Postia placenta. The results showed that decay decreased the content of the principal arylglycerol- beta -aryl ether interunit linkage in the lignin by more than half, while increasing the frequency of several truncated lignin structures roughly fourfold over the level found in sound aspen. These new end-groups, consisting of benzaldehydes, benzoic acids and phenylglycerols, accounted for 6-7% of all original lignin subunits. Our results provide evidence that brown rot by P. placenta results in significant ligninolysis, which might enable infiltration of the wood by polysaccharide hydrolases even though the partially degraded lignin remains in situ. Recent work has revealed that the P. placenta genome encodes no ligninolytic peroxidases, but has also shown that this fungus produces an extracellular Fenton system. It is accordingly likely that P. placenta employs electrophilic reactive oxygen species such as hydroxyl radicals to disrupt lignin in wood.

Efficacy varied by rodenticide tested and rodent species. Generally, rodenticides were more effective against mice than for either of the rat species, and mice tended to consume more rodenticide bait than the laboratory chow alternative food. Efficacy was generally highest for the second-generation anticoagulants tested; however, this varied across products and one-first-generation rodenticide had similar effectiveness. Bait acceptance (palatability) also varied both by rodenticide and by rodent species. Acceptance was the lowest for the acute rodenticides. Bait acceptance appeared to substantially affect the efficacy of rodenticides; materials that were not well accepted produced lower mortality rates. Rodenticide products currently registered for use in Hawaii performed less effectively in this study than other available products not yet registered. Although markets for rodent control products for use on islands are limited, there are advantages to having additional products registered for island use in agriculture, conservation, and public health.

Currently, determination of nutrients in surface water is primarily accomplished by manually collecting samples for laboratory analysis, which requires at least 24h. In other words, little to no effort has been devoted to monitoring real-time variations of nutrients in surface water ecosystems due to the lack of suitable and/or cost-effective wireless sensors. However, when considering human health or instantaneous outbreaks such as algal blooms, timely water-quality information is very critical. In this study, we developed a new paradigm of a dynamic data-driven application system (DDDAS) for estimating the real-time loads of nitrogen (N) in a surface water ecosystem. This DDDAS consisted of the following components: (1) a Visual Basic (VB) program for downloading US Geological Survey real-time chlorophyll and discharge data from the internet; (2) a STELLA model for evaluating real-time N loads based on the relationship between chlorophyll and N as well as on river discharge; (3) a batch file for linking the VB program and STELLA model; and (4) a Microsoft Windows Scheduled Task wizard for executing the model and displaying outputs on a computer screen at selected schedules. The DDDAS was validated using field measurements with a very good agreement prior to its applications. Results show that the real-time loads of TN (total N) and NO x (nitrate and nitrite) varied from positive to negative with the maximums of 1727kg/h TN and 118kg/h NO x and the minimums of a degree 2483kg/h TN and a degree 168kg/h NO x at the selected site. The negative loads occurred because of the back flow of the river in the estuarine environment. Our study suggests that the DDDAS developed in this study was feasible for estimating the real-time variations of TN and NO x in the surface water ecosystem.

Methods and Results: A series of chiral and achiral gossypol derivatives, some natural products of the cotton plant and others prepared by synthesis from gossypol, were incorporated into agar plates to follow the rate of A. flavus isolate AF13 colony growth. All tested compounds exhibited some growth inhibition against this organism. The synthetic compounds, gossypolone and apogossypolone, exhibited greater activity than either racemic or chiral gossypol. Methylated derivatives (i.e. 6-methoxy and 6,6'-dimethoxy derivatives) generally exhibited less activity than the nonmethylated parent compounds. The (-)-optical form of gossypol was found to be slightly more active than the (+)-optical form, and this trend was observed regardless of the presence of methoxy groups at the 6-position. Growth inhibition of gossypolone and apogossypolone was concentration dependent. For gossypolone, the 50% effective dose was 90 mu gml-1 of medium (165 mu moll-1). For apogossypolone, the most active compound in the study, the 50% effective dose was 19 mu gml-1 (38.7 mu moll-1). The presence of gossypol-related terpenoids appeared to stimulate production of A. flavus sclerotia, although replicate variability was so large that it was not possible to determine a significant correlation between the mass of sclerotia formed and compound growth inhibition. Conclusions: The quinone derivatives of gossypol, gossypolone and apogossypolone demonstrated significant fungal growth inhibitory activity against A. flavus. Significance and Impact of the Study: These gossypol derivatives may provide a new class of fungicide for use against the mycotoxigenic fungus A. flavus.

In a series of synthetic twin experiments assimilating surface soil moisture is shown to effectively update SWAT upper-layer soil moisture predictions and provide moderate improvement to lower layer soil moisture and evapotranspiration estimates. However, insufficient SWAT-predicted vertical coupling results in limited updating of deep soil moisture, regardless of the SWAT parameterization chosen for root-water extraction. Likewise, a real data assimilation experiment using ground-based soil moisture observations has only limited success in updating upper-layer soil moisture and is generally unsuccessful in enhancing SWAT stream flow predictions. Comparisons against ground-based observations suggest that SWAT significantly under-predicts the magnitude of vertical soil water coupling at the site, and this lack of coupling impedes the ability of the EnKF to effectively update deep soil moisture, groundwater flow and surface runoff. The failed attempt to improve stream flow prediction is also attributed to the inability of the EnKF to correct for existing biases in SWAT-predicted stream flow components.

LONG-TERM RESEARCH ON ACETOCHLOR, ALACHLOR, METOLACHLOR, AND METRIBUZIN AN - 864957266; 14692898 AB - Farmers in the Midwestern United States continue to be reliant on soil-applied herbicides for weed control in crop production, and herbicide contamination of streams remains an environmental problem. The main objective of this study was to analyze trends in concentration and load of acetochlor, alachlor, metolachlor, and metribuzin in Goodwater Creek Experimental Watershed (GCEW) from 1992 to 2006. A secondary objective was to document the effects of best management practices (BMPs) implemented within GCEW on herbicide transport trends. Median relative herbicide loads, as a percent of applied, were 3.7% for metolachlor, 1.3% for metribuzin, 0.36% for acetochlor, and 0.18% for alachlor. The major decrease in alachlor use and increase in acetochlor use caused shifts in flow-weighted concentrations that were observed over the entire concentration range. The smaller decrease in metolachlor use led to a consistent decreasing time trend only for the upper end of the concentration distribution. Metribuzin also showed moderate decreases in concentration with time since 1998. Annual loads were generally correlated to second quarter discharge. Despite extensive education efforts in the watershed, conservation BMPs within GCEW were mainly implemented to control erosion, and therefore had no discernable impact on reducing herbicide transport. Overall, changes in herbicide use and second quarter discharge had the greatest effect on trends in flow-weighted concentration and annual load.

In each of nine Ren4 pseudo-backcross 2 (pBC sub(2)) and pBC sub(3) populations (1,030 progeny), resistance fit a 1:1 segregation ratio and overall segregated as 543 resistant progeny to 487 susceptible. In full-sib progeny, microscopic observations revealed the reduction of penetration success rate (as indicated by the emergence of secondary hyphae) from 86% in susceptible progeny to below 10% in resistant progeny. Similarly, extreme differences were seen macroscopically. Ratings for Ren4 pBC sub(2) population 03-3004 screened using natural infection in a California vineyard and greenhouse and using artificial inoculation of an aggressive New York isolate were fully consistent among all three pathogen sources and environments. From 2006 to 2010, Ren4 pBC sub(2) and pBC sub(3) vines were continuously screened in California and New York (in the center of diversity for E. necator), and no sporulating colonies were observed. For population 03-3004, severity ratings on leaves, shoots, berries, and rachises were highly correlated (R super(2) = 0.875 to 0.996) in the vineyard. Together, these data document a powdery mildew resistance mechanism not previously described in the Vitaceae or elsewhere, in which a dominantly inherited resistance prevents hyphal emergence and is non-race-specific and tissue-independent. In addition to its role in breeding for durable resistance, Ren4 may provide mechanistic insights into the early events that enable powdery mildew infection.

The pathogen is listed as a quarantine organism by several countries that may have wheat production areas with inadequate or marginal climate for the disease--in particular the People's Republic of China. Field experiments were conducted in the United States in an area of Kansas that is a climatic analog to the northern winter wheat areas of China to evaluate the risk of disease introduction into such areas. The soil surface of four replicate 2.8 x 9.75 m plots, planted with a highly susceptible cultivar, was inoculated with six teliospore concentrations ranging from 0.88 to 88,400 teliospores/cm super(2). A single initial inoculation was done in each of three nurseries planted during separate seasons followed by examination for disease for 4 to 6 years afterward. Any diseased spikes produced were crushed and returned to the plots where they were produced. One nursery had no disease during all six seasons. In two nurseries, the disease was induced at trace levels at the three highest inoculation rates. Disease carryover to the second year occurred during one year in one nursery in plots at the highest inoculation rate, but no disease occurred the following three seasons. A duplicate nursery planted in a disease conducive area in Utah demonstrated that the highest rate of inoculum used in the experiments was sufficient to cause almost 100% infection. This study demonstrated that in an area with marginal climatic conditions it was possible to induce transient trace levels of dwarf bunt, but the disease was not established even with a highly susceptible cultivar and high levels of inoculum. Our results support the conclusions of the 1999 Agreement on U.S.-China Agricultural Cooperation which set a tolerance for teliospores in grain, and supports the Risk Assessment Model for Importation of United States Milling Wheat Containing T. contraversa.

These nematodes could not be placed with certainty into any known species and exhibited some unique morphological features in some specimens. Compared with Globodera pallida, the cyst body length was slightly longer and the second-stage juvenile stylet length was slightly shorter. In some individuals, the J2 stylet knob height was greater and the tail annules were more prominent than in G. pallida, and the tail abruptly narrowed, with a slight constriction near the posterior third of the hyaline terminus. Compared with G. rostochiensis, the hyaline tail terminus had a larger number of refractive bodies, and cysts of this population had a smaller Granek's ratio and fewer cuticular ridges between the anus and vulva. In some individuals, the tail termini of second-stage juveniles were more bluntly pointed, and the stylet knobs were more anteriorly directed with greater height. Unlike G. tabacum, the cyst wall often lacked a network-like pattern and, in some individuals, the juvenile tail terminus distinctly narrowed after a constriction. Molecularly, the population was distinct from G. pallida, G. rostochiensis, and G. tabacum. Multiplex polymerase chain reaction of the internal transcribed spacer (ITS) rDNA region gave results similar to G. tabacum; however, ITS restriction fragment length polymorphism patterns were observed to have individual bands in common with G. rostochiensis and G. pallida. Phylogenetic analysis based on ITS1 and -2 rDNA sequences showed greatest similarity to populations from Argentina and Chile; together, they form a moderately supported clade, distinct from G. rostochiensis, G. tabacum, G. "mexicana," European type G. pallida, and several G. pallida populations from South America.

In a preliminary multisite study, we found that abscission rates of infected leaves were higher at mixed-evergreen sites. In addition, final infection counts were slightly higher at mixed-evergreen sites or not significantly different than at redwood sites, in part due to competition from other foliar pathogens at redwood sites. In a subsequent, detailed study of paired sites where P. ramorum was the main foliar pathogen, summer survival of P. ramorum in bay laurel leaves was lower in mixed-evergreen forest due to lower recovery from infected attached leaves and higher abscission rates of infected leaves. Onset of inoculum production and new infections of bay laurel leaves occurred later in mixed-evergreen forest. Mean inoculum levels in rainwater and final infection counts on leaves were higher in redwood forest. Based on these two studies, lower summer survival of reservoir inoculum in bay laurel leaves in mixed-evergreen forest may result in delayed onset of both inoculum production and new infections, leading to slower disease progress in the early rainy season compared with redwood forest. Although final infection counts also will depend on other foliar pathogens and disease history, in sites where P. ramorum is the main foliar pathogen, these transmission patterns suggest higher rates of disease spread in redwood forests during rainy seasons of short or average length.

Biodegradability of pot type A (composed of 100% polylactic acid (PLA)) was very low (13 +/- 3%) compared to literature values for other PLA materials. Near infrared spectroscopy (NIRS) results suggest that the PLA undergoes chemical structural changes during polymer extrusion and injection molding. These changes may be the basis of the low biodegradability value. Biodegradability of pot types B (containing 5% poultry feather, 80% PLA, 15% starch), and C (containing 50% poultry feather, 25% urea, 25% glycerol), were 53 +/- 2% and 39 +/- 3%, respectively. More than 85% of the total biodegradation of these bioplastics occurred within 38 days. NIRS results revealed that poultry feather was not degraded during composting.

Gray) in Hawai'i, USA aids in restoration of disturbed sites essential to conservation of endemic species. Survival and growth of planted seedlings under vegetative competition typically increases with initial plant size. Increasing container size and fertilizer rate may produce larger seedlings, but high fertilization can lead to surface and groundwater pollution and relatively low fertilizer use efficiency. Subirrigation systems may help mitigate this problem. Our study objective was to evaluate koa seedling growth with overhead or subirrigation over a range of container volumes (50 to 656 mL) and fertilizer rates (0 to 9.6 kg.m-3). Increasing container volume from 50 to 656 mL yielded koa seedlings with 200% more height and stem diameter growth. Subirrigation resulted in less nutrient leaching losses and yielded seedlings of similar vigor as overhead irrigated seedlings. Subirrigation helps optimize fertilizer delivery, which may improve fertilizer use efficiency and reduce environmental contamination.

At the Humboldt site trees that had experienced three to four defoliation events had more negative water potentials and lower foliar Delta 13C than trees farther from the release site that had experienced only one defoliation event. We established paired trees (exposed to D. carinulata and sprayed with insecticide) at both sites and monitored impacts. Beetles reduced stem growth during the first year of defoliation at both sites but not in the second year at the Humboldt site. Defoliation did not affect midday water potentials, or leaf gas exchange during the first two years of defoliation of paired trees at either site. Furthermore there was no difference in foliar Delta 13C in either year at the Humboldt site but defoliation during the first year lead to higher foliar Delta 13C at the Walker site. These results suggest that initial defoliation by D. carinulata reduces growth but not water relations of saltcedar. However, repeated defoliation, potentially acting through reduced root growth, leads to an overall reduction in the water status of this invader.

Oxidative stability was significantly reduced upon extended storage and acid value as well as kinematic viscosity were increased by only small increments, with these effects more pronounced at elevated temperatures. Iodine value and low temperature operability were essentially unaffected by extended storage. Based on these findings, it is not recommended that acid value or kinematic viscosity be used as indicators of storage stability of biodiesel, nor is it recommended that iodine value be used as a predictor of oxidative stability or indicator of oxidative degradation.

AN - 858282827; 20803256 AB - Various species of fungi in the genus Aspergillus are the most common causative agents of invasive aspergillosis and/or producers of hepato-carcinogenic mycotoxins. Salicylaldehyde (SA), a volatile natural compound, exhibited potent antifungal and anti-mycotoxigenic activities to A. flavus and A. parasiticus. By exposure to the volatilized SA, the growth of A. parasiticus was inhibited up to 10-75% at 9.5 mM ≤ SA ≤ 16.0 mM, while complete growth inhibition was achieved at 19.0 mM ≤ SA. Similar trends were also observed with A. flavus. The aflatoxin production, i.e., aflatoxin B(1) and B(2) (AFB(1), AFB(2)) for A. flavus and AFB(1), AFB(2), AFG(1), and AFG(2) for A. parasiticus, in the SA-treated (9.5 mM) fungi was reduced by ~13-45% compared with the untreated control. Using gene deletion mutants of the model yeast Saccharomyces cerevisiae, we identified the fungal antioxidation system as the molecular target of SA, where sod1Δ [cytosolic superoxide dismutase (SOD)], sod2Δ (mitochondrial SOD), and glr1Δ (glutathione reductase) mutants showed increased sensitivity to this compound. Also sensitive was the gene deletion mutant, vph2Δ, for the vacuolar ATPase assembly protein, suggesting vacuolar detoxification plays an important role for fungal tolerance to SA. In chemosensitization experiments, co-application of SA with either antimycin A or strobilurin (inhibitors of mitochondrial respiration) resulted in complete growth inhibition of Aspergillus at much lower dose treatment of either agent, alone. Therefore, SA can enhance antifungal activity of commercial antifungal agents required to achieve effective control.

Therefore, lipid metabolome-wide responses and their relationships with endocrine (cortisol, insulin, and adiponectin) responsiveness to acute stress (AS) were assessed in a primate model of chronic social stress (CS). Compared to controls (not exposed to CS), CS increased (P<=0.05) circulating triacylglycerol (TG) and phosphatidylethanolamine (PE) n-6/n-3 and reduced (P<=0.05) cholesterol ester (CE) 16:1n7 and phosphatidylcholine (PC) 18:1n7, suggesting lower omega-3 FA status and stearoyl-CoA desaturase activity, respectively. Cortisol responses to AS positively correlated with TG n-6/n-3 (r=0.93; P=0.007), but only in CS monkeys. The adiponectin response to AS inversely correlated with CE n-6/n3 (r=-0.89; P=0.045) and positively with TG 16:1n7 (r=0.98; P=0.004), only in CS monkeys. Our results are consistent with previously reported FA profiles in stress-related psychopathology and suggest that compositional changes of specific lipid FAs may form new functional markers of chronic psychological stress.

In particular, we employ a new 1985-2005 provincial panel dataset together with a stochastic output distance frontier framework to examine how government policies have affected the nation's agricultural productivity, decomposing it into its technical progress and efficiency components. Government's primary contributions to technology growth have come through price and trade policies rather than public research. Most technology growth, however, appears to be due to informal technology diffusion.

The initial objective of this study was to determine whether this oxygen uptake burst was a result of increased bacterial multiplication, possibly due to nutrient leakage from plant cells. The adaptation of flow cytometry and the use of fluorescent nucleic acid stains provided the precision needed to monitor bacterial concentrations in tobacco suspension cells inoculated with pathogenic and non-pathogenic Pseudomonas species. Surprisingly, there was a transient decrease in the planktonic, or free-living, bacteria in cell suspensions inoculated with isolate Pseudomonas syringae pv. syringae WT (HR+), an incompatible pathogen of tobacco. This decrease in planktonic numbers was followed by an apparent increase in bacterial multiplication. Examination of the samples with fluorescent microscopy revealed the formation of bacterial aggregates in the extracellular fluid of the Pss WT (HR+) inoculated plant cells. The size of the aggregates increased at the onset of the oxygen uptake response, and contained increasing numbers of bacterial cells. These aggregated bacterial cells appear to be removed along with plant cells, as a result of filtration during sample preparation, causing the apparent decrease in planktonic bacteria detected by flow cytometry. This bacterial aggregation was also observed with the compatible Pseudomonas tabaci pathogen, which does not induce a noticeable oxygen uptake burst. No aggregation was observed with suspension inoculated with Pseudomonas fluorescens, a saprophyte, or Pss B7 (HR-), a Tn5 mutant of P. s. syringae. This aggregation response was rapid, once initiated, and appeared similar to reports of adhesion involving Hrp pili.

14607454 AB - Microbial diversity associated with micropropagated Atriplex species was assessed using microscopy, isolate culturing, and sequencing. Light, electron, and confocal microscopy revealed microbial cells in aseptically regenerated leaves and roots. Clone libraries and tag-encoded FLX amplicon pyrosequencing (TEFAP) analysis amplified sequences from callus homologous to diverse fungal and bacterial taxa. Culturing isolated some seed borne endophyte taxa which could be readily propagated apart from the host. Microbial cells were observed within biofilm-like residues associated with plant cell surfaces and intercellular spaces. Various universal primers amplified both plant and microbial sequences, with different primers revealing different patterns of fungal diversity. Bacterial and fungal TEFAP followed by alignment with sequences from curated databases revealed 7 bacterial and 17 ascomycete taxa in A. canescens, and 5 bacterial taxa in A. torreyi. Additional diversity was observed among isolates and clone libraries. Micropropagated Atriplex retains a complex, intimately associated microbiome which includes diverse strains well poised to interact in manners that influence host physiology. Microbiome analysis was facilitated by high throughput sequencing methods, but primer biases continue to limit recovery of diverse sequences from even moderately complex communities.

The present study determined the protective efficacy of two Neospora antigens - Neospora cyclophilin (NcCyP) and NcSRS2. The ability of native NcCyP to upregulate mouse IFN- gamma was also confirmed in this study. Recombinant NcCyP or NcSRS2 were tested either alone or in combination and formulated with adjuvant ImmuMax-SR and CpG. Female BALB/c mice (n = 15) of 10-12 weeks of age were immunized s.c. twice over a 2-week interval with vaccines containing either NcCyP (20 [micro]g/dose) alone, NcSRS2 (20 [micro]g/dose) alone, NcCyP plus NcSRS2, or non-recombinant bacterial antigen (NR) in 2 separate trials. All mice were challenge-infected 3 weeks following the booster immunization and necropsied 3 weeks after the challenge infection. Brain and serum were collected and Nc-specific DNA sequence in brain tissue and antibodies in serum were analyzed by PCR or ELISA/Western blotting. Results showed that mice vaccinated with rNcCyP, rNcSRS2, or both rNcCyP and rNcSRS2 responded with high levels of NcCyP or NcSRS2 specific antibodies. Overall, mice received vaccines formulated with either rNcCyP or rNcCyP and rNcSRS2 had a higher (p < 0.01) percent protection when compared to the mock- or non-vaccinated mice. The group immunized with rNcSRS2 alone exhibited slightly lower levels of protection, which was higher (p < 0.05) than that of the non-vaccinated group but did not differ (p = 0.06) from that of the mock-vaccinated group. The results of the present study indicate that NcCyP is a highly efficacious vaccine candidate which may be useful in protection against Neospora infection.

Micelle templated silicas with a specific pore size were synthetically modified to possess propylthiol groups, a functional group known to form Michael reaction products with the conjugated double bond system of patulin. BET surface area analysis indicated the propylthiol functionalized SBA-15 possesses channels with the pore size of 5.4nm and a surface area of 345m super(2) g super(-1). Elemental analysis indicates the silicon/sulfur ratio to be 10:1, inferring one propylthiol substituent for every ten silica residues. The propylthiol modified SBA-15 was effective at significantly reducing high levels of patulin from aqueous solutions (pH 7.0) in batch sorption assays at room temperature. The material was less effective at lower pH; however heating low pH solutions and apple juice to 60 degree C in the presence of propylthiol functionalized SBA-15 significantly reduced the levels of patulin in contaminated samples. Composite molecular models developed by semi-empirical PM3 and empirical force field methods support patulin permeation through the mesoporous channels of propylthiol functionalized SBA-15. Density functional study at the B3LYP/6-31G(d,p) level predicts the proposed patulin adducts formed by reaction with the thiol residues exhibit less electrophilic properties than patulin. It is demonstrated the use of propylthiol functionalized SBA-15 is a viable approach to reduce patulin levels in aqueous solutions, including contaminated apple juice.

In this case study, we examined the effect of riparian buffer width on stream water quality following upland forest management activities in four headwater catchments. Three riparian buffer widths were delineated prior to cutting; 0m (no-buffer), 10m, and 30m, and one reference site (REF). A two-age prescription timber harvest was conducted on all cut sites with a target residual basal area of approximately 4.0m super(2) ha super(-1). Harvesting occurred from October 2005 through February 2007. Stream sampling was conducted weekly from January 2004 through December 2008. Stream water chemistry, temperature, and total suspended solids (TSS) were used as metrics of water quality. Analyses were conducted on weekly grab samples. Pre-treatment concentrations of all solutes were similar to conditions found in other headwater streams at similar topographic positions around the region. The greatest responses to cutting occurred on the no-buffer site. Compared with pre-harvest levels on the no-buffer site, stream nitrate concentration ([NO sub(3)-N]) increased 2-fold during both base and stormflow following harvest, and all base cations increased in concentration. [NO sub(3)-N] on the no-buffer site showed steady decline with time following the initial post-harvest increase. The other sites did not show increases in [NO sub(3)-N] and very small or no responses in other stream chemistry parameters. There was no TSS response at stormflow on any site, and during baseflow, TSS decreased on all but the no-buffer site. Stream water temperature increased during the summer on the no-buffer site. Although alternative land uses may have different requirements, these results suggest that for riparian buffer widths of 10m and wider, the forest harvest activities implemented in this study did not substantially impact stream water quality.

Forests contain the world's largest terrestrial carbon stocks, but in seasonally dry environments stock stability can be compromised if burned by wildfire, emitting carbon back to the atmosphere. Treatments to reduce wildfire severity can reduce emissions, but with an immediate cost of reducing carbon stocks. In this study we examine the tradeoffs in carbon stock reduction and wildfire emissions in 19 fuels-treated and -untreated forests burned in twelve wildfires. The fuels treatment, a commonly used thinning 'from below' and removal of activity fuels, removed an average of 50.3Mg C haa degree 1 or 34% of live tree carbon stocks. Wildfire emissions averaged 29.7 and 67.8Mg C haa degree 1 in fuels treated and untreated forests, respectively. The total carbon (fuels treatment plus wildfire emission) removed from treated sites was 119% of the carbon emitted from the untreated/burned sites. However, with only 3% tree survival following wildfire, untreated forests averaged only 7.8Mg C haa degree 1 in live trees with an average quadratic mean tree diameter of 21cm. In contrast, treated forest averaged 100.5Mg C haa degree 1 with a live tree quadratic mean diameter of 44cm. In untreated forests 70% of the remaining total ecosystem carbon shifted to decomposing stocks after the wildfire, compared to 19% in the fuels-treated forest. In wildfire burned forest, fuels treatments have a higher immediate carbon 'cost', but in the long-term may benefit from lower decomposition emissions and higher carbon storage.

Diurnal fluctuation in a tree's stem diameter is a function of daily growth and of the tree's water balance, as water is temporarily stored in the relatively elastic outer cambial and phloem tissues. On a very productive site in southwestern Washington, U.S.A., we used recording dendrometers to monitor stem diameter fluctuations of Douglas-fir at plantation ages 7 and 8 and related the fluctuations to environmental variables measured on-site. Growing-season diurnal stem contraction (DSC) averaged 0.21% of stem diameter, while dormant-season DSC averaged 0.03% of stem diameter. Maximum daily stem diameter generally occurred between 7:00 and 9:00 Pacific Standard Time (PST) and minimum stem diameter occurred between 17:00 and 20:00PST. Diurnal stem contraction during the growing season was predicted by a model that included vapor pressure deficit and solar radiation (adjusted R 2 =0.84). A similar model predicted DSC during the dormant season with an adjusted R 2 =0.26. Soil water availability was high, and soil water content was not correlated with DSC. On four of the coldest winter days (mean daytime air temperature <0A degree C), large decreases in stem diameter were observed. Recording dendrometers, used for continuous diameter measurements throughout the growing season, have the potential to provide important information not only on tree growth but also on a tree's water balance.

The objectives of this study were to investigate water use and canopy level photosynthesis of corn plants, and to quantify water use efficiency in corn plants under two different CO sub(2) levels combined with four different water stress levels. Corn plants were planted in sunlit plant growth chambers and a day/night temperature of (28/18 degree C) was applied. From 21 days after emergence (DAE), the eight treatments including two levels of carbon dioxide concentrations (400 and 800 mu mol mol super(-1)) and four levels of water stress (well-watered control, "mild", "moderate", and "severe" water stress) treatments at each CO sub(2) level were imposed. Height, number of leaves, leaf lengths, and growth stages of corn plants were monitored from nine plants twice a week. Corn plants were separately collected, dried, and analyzed for the biomass accumulation at 21 and 60 DAE. Soil water contents were monitored by a time domain reflectometry (TDR) system (15 probes per chamber). The "breaking points" (changes from high to low rates of soil water uptake) were observed in the bottom of soil depth for the water stressed conditions, and the "breaking points" under ambient CO2 appeared 6-9 days earlier than under elevated CO sub(2). Although approximately 20-49% less water was applied for the elevated CO sub(2) treatments than for ambient CO sub(2) from 21 DAE, higher soil water contents were recorded under elevated CO sub(2) than under ambient CO sub(2). However, corn growth variables such as height, leaf area, and biomass accumulation were not significantly different in CO sub(2) or water stressed treatments. This result may be explained by considering that significant differences in canopy level gross photosynthesis among the water stress treatments was observed only toward the end of the experiment. The higher soil water contents observed under elevated CO sub(2) resulted mainly from less water use than under ambient CO sub(2). WUE (above ground biomass per water use since 21 DAE) at the final harvest was consistently higher and varied with a smaller range under elevated CO sub(2) than under ambient CO sub(2). This study suggests that less water will be required for corn under high-CO sub(2) environment in the future than at present.

This method shows some potential for modeling spatial and temporal variation in cold air drainage in regions of complex topography. Accurate, fine spatial resolution predictions of surface air temperatures are critical for understanding many hydrologic and ecological processes. This study examines the spatial and temporal variability in nocturnal air temperatures across a mountainous region of Northern Idaho. Principal components analysis (PCA) was applied to a network of 70 Hobo temperature loggers systematically distributed across 2 mountain ranges. Four interpretable modes of variability were observed in average nighttime temperatures among Hobo sites: (1) regional/synoptic; (2) topoclimatic; (3) land surface feedback; (4) canopy cover and vegetation. PC time series captured temporal variability in nighttime temperatures and showed strong relationships with regional air temperatures, sky conditions and atmospheric pressure. PC2 captured the topographic variation among temperatures. A cold air drainage index was created by predicting PC2 loadings to elevation, slope position and dissection indices. Nightly temperature maps were produced by applying PC time series back to the PC2 loading surface, revealing complex temporal and spatial variation in nighttime temperatures. Further development of both physically and empirically based daily temperature models that account for synoptic atmospheric controls on fine-scale temperature variability in mountain ecosystems are needed to guide future monitoring efforts aimed at assessing the impact of climate change.

AN - 855207383; 21314127 AB - The peanut plant (Arachis hypogaea L.), when infected by a microbial pathogen, is capable of producing stilbene-derived compounds that are considered antifungal phytoalexins. In addition, the potential health benefits of other stilbenoids from peanuts, including resveratrol and pterostilbene, have been acknowledged by several investigators. Despite considerable progress in peanut research, relatively little is known about the biological activity of the stilbenoid phytoalexins. This study investigated the activities of some of these compounds in a broad spectrum of biological assays. Since peanut stilbenoids appear to play roles in plant defense mechanisms, they were evaluated for their effects on economically important plant pathogenic fungi of the genera Colletotrichum, Botrytis, Fusarium, and Phomopsis. We further investigated these peanut phytoalexins, together with some related natural and synthetic stilbenoids (a total of 24 compounds) in a panel of bioassays to determine their anti-inflammatory, cytotoxic, and antioxidant activities in mammalian cells. Several of these compounds were also evaluated as mammalian opioid receptor competitive antagonists. Assays for adult mosquito and larvae toxicity were also performed. The results of these studies reveal that peanut stilbenoids, as well as related natural and synthetic stilbene derivatives, display a diverse range of biological activities.

Earlier floral anthesis has been suggested, in turn, to have a role in human disease by increasing time of exposure to pollen that causes allergic rhinitis and related asthma. However, earlier floral initiation does not necessarily alter the temporal duration of the pollen season, and, to date, no consistent continental trend in pollen season length has been demonstrated. Here we report that duration of the ragweed (Ambrosia spp.) pollen season has been increasing in recent decades as a function of latitude in North America. Latitudinal effects on increasing season length were associated primarily with a delay in first frost of the fall season and lengthening of the frost free period. Overall, these data indicate a significant increase in the length of the ragweed pollen season by as much as 13-27 d at latitudes above approximately 44 degree N since 1995. This is consistent with recent Intergovernmental Panel on Climate Change projections regarding enhanced warming as a function of latitude. If similar warming trends accompany long-term climate change, greater exposure times to seasonal allergens may occur with subsequent effects on public health.

Various surfaces, including plant material, personnel and equipment can become contaminated. Decontamination is practiced in both disease-endemic and disease-free areas to reduce the risk of bacterial spread by man or machinery. We used grapefruit leaf surfaces to explore the efficacy of a commonly used personnel sprayer system applying a quaternary amine decontaminant. In three experiments, plants in flush (leaves 3/4 expanded) were inoculated (10[super]5 CFU ml[super]-1). Immediately after inoculation, plants were passed through the sprayers 0, 1, 2, 3, or 6 times. Leaves were sampled at 0.5, 10 and 20 min after decontamination and tested for viable Xcc by dilution plating. There was a large and rapid decline in the quantity of live bacteria with one pass through the decontamination sprayer (>80% decrease in CFU ml[super]-1), and multiple sprays (2-6) resulted in up to 100% mortality of surface Xcc. Presumably more thorough coverage with multiple sprays killed remnant bacteria, although the first spray invariably caused the highest proportion of population mortality. The effect of the decontaminant spray was immediate (within 0.5 min only 3-11% of surface bacteria survived, and by 20 min <1-3% survived). Based on these results, use of a personnel sprayer with a quaternary amine compound is highly effective for reducing surface inoculum. A single spray kills a high proportion of the population, but multiple sprays increase mortality of Xcc. All the Xcc-inoculated plants subsequently developed symptoms of citrus canker. No significant difference in incidence or severity of grapefruit leaf infection was detected among decontamination treatments or compared to the untreated control. This finding indicates that infection occurred at, or very soon after, inoculation, and that Xcc was in protected sites inside the leaf before exposure to the decontaminant spray.

Feral swine populations have since grown in these counties which also contain a high density of commercial production swine (CPS) facilities. Sixteen of the highest swine producing U.S. counties also populated with feral swine are in North Carolina. Disconcertingly, since 2009, positive tests for exposure to swine brucellosis or pseudorabies virus have been found for feral swine. We surveyed 120 CSP facilities across four eastern counties to document the level and perception of feral swine activity around CSP facilities and to identify disease transmission potential to commercial stock. Nearly all facility operators (97%) recognized feral swine were in their counties. Far fewer said they had feral swine activity nearby (18%). Our inspections found higher presence than perceived with feral swine sign at 19% of facilities where operators said they had never observed feral swine or their sign. Nearly 90% expressed concern about feral to domestic disease transmission, yet only two facilities had grain bins or feeders fenced against wildlife access. Due to increasing feral swine populations, recent evidence of disease in feral populations, the importance of swine production to North Carolina's economy and the national pork industry, and potential for feral-domestic contact, we believe feral swine pose an increasing disease transmission threat warranting a stringent look at biosecurity and feral swine management at North Carolina CPS facilities.

Growth AN - 918045939; 14379420 AB - Further study is needed on loblolly pine (Pinus taeda L.) growth in a systematic array of plantation designs or stocking rates commonly used in temperate forestry and agroforestry practices. Our objective was to determine loblolly pine growth responses and agroforestry implications of 13 plantation designs (i.e., stocking rates in trees ha super(-1) [TPH]) at mid-rotation (14years old). Survival, diameter at 1.3m above soil surface (dbh), height, basal area (BA), and volume (V) were measured in unthinned plantations ranging from 490 to 2,300 TPH. Stocking rate was positively correlated with BA (r greater than or equal to 0.67) and V (r greater than or equal to 0.55) and negatively correlated with survival (r less than or equal to -0.83) and dbh (r less than or equal to -0.83). Plantations with greater than or equal to 2,000 TPH had closed canopies and excessively high BA and V at mid-rotation. The 4- and 5-row plantations ( greater than or equal to 12m alley spacing) had small dbh ( less than or equal to 17.5cm). Single-row plantations with greater than or equal to 3.6m within row spacing and less than or equal to 700 TPH, and the 3-row multiple-row plantations (1,200 TPH), had acceptable BA (29.4-33.2m super(2) ha super(-1)) and V (127-136m super(3)ha super(-1)). Basal area was greater than or equal to 30m super(2)h a super(-1) in most plantations indicating thinning is needed to optimize individual tree growth. Besides timber, an array of design-dependent agroforestry and forestry products should drive the selection of any one of these plantation designs: pine straw or biomass production at greater than or equal to 1,800 TPH, and alley cropping or silvopasture in single-row ( less than or equal to 1,000 TPH) and multiple-row plantations (<1,400 TPH).

Profitability AN - 918045937; 14379419 AB - Financial analyses are needed for the wide array of plantation designs commonly used in loblolly pine (Pinus taeda L.) forestry and agroforestry practices. Our objective was to develop an economic model to estimate financial outputs at mid-rotation (14years old) for 13 loblolly pine stands (plantations) with 546 to 3067 trees ha super(-1) (TPH). The Excel model allowed costs, returns, growth, and production scenarios to be varied to calculate net present value (NPV) and years to "break even" with and without pine straw. Plantations with greater than or equal to 2100 TPH and no pine straw harvest had negative NPV and a relatively long break-even period than other plantations at a 5% discount rate. Pine straw harvesting nearly doubled NPV at about 1500 TPH compared to no pine straw, and substantially reduced years to break even at <1500 TPH. There was little difference in NPV between multiple-row plantations. Single-row plantations with greater than or equal to 1500 TPH should be considered only if pine straw is harvested or a lower discount rate is used. Pine straw harvesting probably would be impractical for the single-row plantations with <1100 TPH, and 2-row and 3-row multiple-row plantations due to low stocking rate and partially open canopies. The model demonstrated the potential financial benefit for harvesting pine straw with timber, especially in the south-central US where pine straw is an underutilized resource.

However, numerous other non-O157 STEC strains are associated with diseases of various severities and have become an increasing concern to the beef industry, regulatory officials, and the public. This study reports on the prevalence and characterization of non-O157 STEC in commercial ground beef samples (n = 4,133) obtained from numerous manufacturers across the United States over a period of 24 months. All samples were screened by DNA amplification for the presence of Shiga toxin genes, which were present in 1,006 (24.3%) of the samples. Then, culture isolation of an STEC isolate from all samples that contained stx1 and/or stx2 was attempted. Of the 1,006 positive ground beef samples screened for stx, 300 (7.3% of the total of 4,133) were confirmed to have at least one strain of STEC present by culture isolation. In total, 338 unique STEC isolates were recovered from the 300 samples that yielded an STEC isolate. All unique STEC isolates were serotyped and were characterized for the presence of known virulence factors. These included Shiga toxin subtypes, intimin subtypes, and accessory virulence factors related to adherence (saa, iha, lifA), toxicity (cnf, subA, astA), iron acquisition (chuA), and the presence of the large 60-MDa virulence plasmid (espP, etpD, toxB, katP, toxB). The isolates were also characterized by use of a pathogenicity molecular risk assessment (MRA; based on the presence of various O-island nle genes). Results of this characterization identified 10 STEC isolates (0.24% of the 4,133 total) that may be considered a significant food safety threat, defined by the presence of eae, subA, and nle genes.

DNA G+C content was 52.8mol% which is within the range reported for E. asburiae (55-57mol%). The major cellular fatty acids present in the LF7 strain were C sub(16:0) (27.3%), C sub(16:1) omega 7c and/or C sub(16:1) omega 6c (16.3%), C sub(18:1) omega 7c (16.1%), C sub(17:0) cyclo (12.4%), C sub(14:0) 3-OH and/or C sub(16:1) iso-I (8.9%), C sub(14:0) (7.6%), C sub(12:0) (3.9%), C sub(17:0) (2.4%), C sub(13:0) 3-OH and/or C sub(15:1) iso-H (1.7%), C sub(13:0) (1.1%), and C sub(18:2) omega 6,9c and/or C sub(18:0) ante (0.5%). The cellular fatty acid profile, G+C content, phenotypic and biochemical characteristics were consistent with its placement in the genus Enterobacter. The name Enterobacter soli is proposed for this bacterium.

In irradiated sterile ground beef, YPST replicated from 0 to 30 degree C, with corresponding growth rates (GR) ranging from 0.023 to 0.622logCFU/h at 0-25 degree C, and the GR was 0.236logCFU/h at 30 degree C. The maximum population densities (MPD) ranged from 8.7 to 11.0logCFU/g. The growth and MPD of YPST were reduced significantly at 30 degree C. Models for GR and MPD of YPST in raw ground beef (RGB) as a function of storage temperatures were produced and displayed acceptable bias and accuracy. The models were validated with rifampicin-resistant YPST (rif-YPST) in sterile ground beef stored at 4, 10 and 25 degree C. The observed GR and MPD were within 95% of the predicted values. When compared to non-sterile retail ground beef, the growth of rif-YPST was not inhibited and displayed similar GR at 0, 10 and 25 degree C and MPDs as sterile ground beef at 10 and 25 degree C. Moreover, there was no loss of virulence plasmid in YPST during its growth in ground beef indicating that RGB contaminated with virulence plasmid-bearing YPST could cause disease due to refrigeration failure, temperature (10-25 degree C) abuse, and if the meat was not properly cooked.

One class of newly-described, Ca2+-dependent, salivary apyrases known to counteract blood-clotting, has been identified in haematophagous arthropods. Herein, we have identified a gene (Oos-apy-1) encoding a protein that structurally conforms to the Ca2+-activated apyrase from the bed bug, Cimex lectularius, by immunologically screening an Ostertagia L4 cDNA expression library. The expressed protein (rOos-APY-1) was biochemically functional in the presence of Ca2+ only, with greatest activity on ATP, ADP, UTP and UDP. Host antibodies to the fusion protein appeared as early as 14 days post-infection (p.i.) and increased through 30 days p.i. Immunohistochemical and Western blot analyses demonstrated that the native Oos-APY-1 protein is present in the glandular bulb of the oesophagus and is confined to the L4. A putative signal sequence at the N-terminus and near 100% identity with a Teladorsagia circumcincta L4 secreted protein is consistent with the native protein being secreted at the cellular level. Predicated upon substrate specificity, the native protein may be used by the parasite to control the levels of host extracellular nucleotides released by locally-damaged tissues in an effort to modulate immune intervention and inflammation.

It was suggested that the unique acid tolerance of Shigella boydii 18 CDPH, the strain implicated in a 1998 outbreak, may have played an important role in surviving the acidic food (bean salad). The strain was capable of inducing arginine-dependent acid-resistance (ADAR) pathway. This pathway was assumed to be absent in Shigella sp. Here, we have examined occurrence and efficacy of ADAR pathway in 21 S. boydii strains obtained from the American Type Culture Collection (ATCC) along with strains of S. flexneri (n=7), S. sonnei (n=4), and S. dysenteriae (n=2). The eight S. boydii strains were able to induce ADAR to survive the acid challenge at pH 2.0; additional 8 strains could tolerate acid challenge at pH 2.5 but not at pH 2.0. The remaining five S. boydii strains were not able to induce ADAR pathway and could not survive acid challenge even at pH 2.5. ADAR pathway also appears to be present in all four Shigella sp. Shigella ADAR pathway was induced when cells were grown under partial oxygen pressure while its expression in E. coli required mere fermentative growth on glucose.

Entomopathogenic fungi could provide a viable component for an integrated pest management strategy for control of B. cockerelli and other potato pest insects. Three field trials of commercial formulations of Metarhizium anisopliae (F 52[registered], Novozymes Biologicals) and Isaria fumosorosea (Pfr 97[registered], Certis USA) and abamectin (Agri-Mek[registered], Syngenta, USA) were conducted in Weslaco, Texas. Rates are expressed in quantity of product delivered in 375-470 l of water/ha. F 52 applied at 0.51, 1.1, and 2.2 l/ha and Agri-Mek applied at 584 ml/ha produced reductions of B. cockerelli eggs and nymphs of 45%, 59%, 67%, and 63%, respectively. Only Agri-Mek significantly reduced plant damage. Pfr 97 at 1.1 kg/ha with and without 1% Trilogy[registered] (neem oil, Certis, USA), and Agri-Mek at 584 ml/ha resulted in psyllid reductions of 78%, 76%, and 84%, respectively. Significantly decreased plant damage and ZC symptoms were observed for all treatments. Tuber yields for Pfr plus Trilogy and Agri-Mek were significantly higher than the control. F 52 applied at 1.1 and 2.2 l/ha and Pfr 97 at 1.1 and 2.2 kg/ha produced 62%, 62%, 66%, and 65% reduction, respectively. Tuber yield for both rates of Pfr and the high rate of F 52 were significantly higher than the control. All fungal treatments significantly reduced plant damage and ZC symptoms.

Factors dictating the extent to which competitive displacement occurs during host infection are unknown. The role of initial host contact in competition between pairs of A. flavus isolates coinfecting maize kernels was examined. Isolate success during tissue invasion and reproduction was assessed by quantification of isolate-specific single nucleotide polymorphisms using pyrosequencing. Isolates were inoculated either simultaneously or 1 h apart. Increased success during competition was conferred to the first isolate to contact the host independent of that isolate's innate competitive ability. The first-isolate advantage decreased with the conidial concentration, suggesting capture of limited resources on kernel surfaces contributes to competitive exclusion. Attempts to modify access to putative attachment sites by either coating kernels with dead conidia or washing kernels with solvents did not influence the success of the first isolate, suggesting competition for limited attachment sites on kernel surfaces does not mediate first-isolate advantage. The current study is the first to demonstrate an immediate competitive advantage conferred to A. flavus isolates upon host contact and prior to either germ tube emergence or host colonization. This suggests the timing of host contact is as important to competition during disease cycles as innate competitive ability. Early dispersal to susceptible crop components may allow maintenance within A. flavus populations of genetic types with low competitive ability during host tissue invasion.

Aphid proteins differentially expressed in F2 Schizaphis graminum genotypes segregating for the ability to transmit Cereal yellow dwarf virus-RPV (CYDV-RPV) were identified using two-dimensional difference gel electrophoresis (DIGE) coupled to either matrix-assisted laser desorption ionization-tandem mass spectrometry or online nanoscale liquid chromatography coupled to electrospray tandem mass spectrometry. A total of 50 protein spots, containing aphid proteins and proteins from the aphid's obligate and maternally inherited bacterial endosymbiont, Buchnera, were identified as differentially expressed between transmission-competent and refractive aphids. Surprisingly, in virus transmission-competent F2 genotypes, the isoelectric points of the Buchnera proteins did not match those in the maternal Buchnera proteome as expected, but instead they aligned with the Buchnera proteome of the transmission-competent paternal parent. Among the aphid proteins identified, many were involved in energy metabolism, membrane trafficking, lipid signaling, and the cytoskeleton. At least eight aphid proteins were expressed as heritable, isoelectric point isoform pairs, one derived from each parental lineage. In the F2 genotypes, the expression of aphid protein isoforms derived from the competent parental lineage aligned with the virus transmission phenotype with high precision. Thus, these isoforms are candidate biomarkers for CYDV-RPV transmission in S. graminum. Our combined genetic and DIGE approach also made it possible to predict where several of the proteins may be expressed in refractive aphids with different barriers to transmission. Twelve proteins were predicted to act in the hindgut of the aphid, while six proteins were predicted to be associated with the accessory salivary glands or hemolymph. Knowledge of the proteins that regulate virus transmission and their predicted locations will aid in understanding the biochemical mechanisms regulating circulative virus transmission in aphids, as well as in identifying new targets to block transmission.

Estimates indicate that 40 to 80% of infants infected with Cronobacter sakazakii and/or Salmonella in the United States may not survive the illness. A systematic approach, combining literature-based data mining, comparative genome analysis, and the direct sequencing of PCR products of specific biomarker genes, was used to construct an initial collection of genes to be targeted. These targeted genes, particularly genes encoding virulence factors and genes responsible for unique phenotypes, have the potential to function as biomarker genes for the identification and differentiation of Cronobacter spp. and Salmonella from other food-borne pathogens in low-moisture food products. In this paper, a total of 58 unique Salmonella gene clusters and 126 unique potential Cronobacter biomarkers and putative virulence factors were identified. A chitinase gene, a well-studied virulence factor in fungi, plants, and bacteria, was used to confirm this approach. We found that the chitinase gene has very low sequence variability and/or polymorphism among Cronobacter, Citrobacter, and Salmonella, while differing significantly in other food-borne pathogens, either by sequence blasting or experimental testing, including PCR amplification and direct sequencing. This computational analysis for Cronobacter and Salmonella biomarker identification and the preliminary laboratory studies are only a starting point; thus, PCR and array-based biomarker verification studies of these and other food-borne pathogens are currently being conducted.

In addition to chromosomal virulence genes, STEC strains usually harbor a large plasmid that carries genes associated with pathogenicity. The complete nucleotide sequence and genetic organization of 6 plasmids carried by STEC O26:H11 strain H30 were determined. The large virulence plasmid (pO26-Vir) was approximately 168 kb in size and contained 196 open reading frames (ORFs). pO26-Vir possesses a mosaic structure and shows similarity to the virulence plasmids in locus of enterocyte effacement (LEE)-negative STEC O113:H21 EH41 (pO113), in E. coli clinical strain C1096 (pSERB1), and in E. coli O157:H7 RIMD 0509952 (pO157). Plasmid pO26-Vir shares several highly conserved regions with pO157 and carries important virulence genes, including toxB, katP, espP, and the hly gene cluster. In addition, pO26-Vir possesses genes encoding for type IV pili (pilL-V). The second largest plasmid, pO26-L (73 kb) contains 101 ORFs. pO26-L carries the tetracycline resistance gene and has regions that show similarity to the E. coli conjugative resistance plasmid NR1. The third largest plasmid, pO26-S4 (5.8 kb), is homologous to the ColE2 colicinogenic plasmid that encodes for colicin E2. The remaining 3 plasmids, pO26-S1 (1.5 kb), pO26-S2 (3.1 kb), and pO26-S3 (4.2 kb), carry very little genetic information except for putative proteins involved in plasmid replication and DNA maintenance. The data presented underscore the diversity among the STEC virulence plasmids and provide insights into the evolution of these plasmids in STEC strains that cause serious human illness.

Understanding which factors affect overlap of home range by various segments (i.e., age, sex) of an urban deer population has implications to direct contact between deer on disease epidemiology. We assessed size of home range and overlap of space use using the volume of intersection index (VI) for deer in an urban landscape by sex, age, season, and time of day. We found mean space use was larger for males than for females, for males <3 years old than for males greater than or equal to 3 years old, and during nocturnal hours compared with diurnal hours. We also identified larger space use by both sexes during the nongrowing than the growing season. Overlap of space use for female and male deer in our urban landscape differed considerably depending on demographic (i.e., age) and environmental variables (i.e., time, season). For example, highest mean VIs occurred between 6-year-old females (mean=0.51+/-0.10) and 5- and 6-year-old males (mean=0.49+/-0.14); no mean VI was greater than 0.31 between females and males for any age combination. Variation in overlap of space use for urban deer provides new information for managing deer-human conflicts and direct transmission of disease between various segments of a deer population in an urban landscape.

S. T. Blake. Populations of the weevil increased rapidly and became widely distributed throughout much of the invasive tree's adventive distribution. In this study we ask if O. vitiosa has acquired natural enemies in Florida, how these enemies circumvent the protective terpenoid laden exudates on larvae, and what influence 1 of the most common natural enemies has on O. vitiosa population densities? Surveys of O. vitiosa populations and rearing of field-collected individuals resulted in no instances of parasitoids or pathogens exploiting weevil eggs or larvae. In contrast, 44 species of predatory arthropods were commonly associated (>5 individuals when pooled across all sites and sample dates) with O. vitiosa. Eleven predatory species were observed feeding on O. vitiosa during timed surveys, including 6 pentatomid species, 2 formicids and 3 arachnids. Species with mandibulate or chelicerate mouthparts fed on adult stages whereas pentatomids, with haustellate beaks, pierced larval exoskeletons thereby bypassing the protective larval coating. Observations of predation were rare, with only 8% of timed surveys resulting in 1 or more instances of attack. Feeding by the pentatomid Podisus mucronatus Uhler accounted for 76% of all recorded predation events. Podisus mucronatus numerically responded to fourth instars but no response was observed for other life stages. Damage to M. quinquenervia plants from feeding by O. vitiosa, however, was not influenced by P. mucronatus densities, indicating that predation does not alter plant suppression.

First, visual features were evaluated. Standard CDC traps were modified to have black or white catch bags, black or white lids, or no lids and these were tried in different combinations. Significantly more male sand flies were caught by darker traps; significantly more females were captured by traps with either all black or a combination of black and white features. Attraction may be due to dark color or contrast in colors. CDC traps with suction and the following features were also evaluated: no light; incandescent light; ultraviolet (UV) light; combination of black color, heat and moisture; CO2 alone, or a combination of black color, heat, moisture, and CO2 simultaneously, all in upright and inverted positions, with the opening for insect entry always 50 cm above the ground. Significantly more females than males were caught by all traps (standard and inverted) except the control traps with suction only. Traps with CO2 caught more sand flies than traps without CO2 Traps with black color, heat and moisture captured significantly more sand flies than the control traps, but with the addition of CO2, these traps catch significantly more sand flies than the other traps evaluated. Inverting traps increased the catch for like traps by about two times.

The traps differed in physical appearance, amount of carbon dioxide produced and released, type and location of capturing device, and the method by which the trap suction fans were powered. The traps tested were the Mosquito MagnetTM(MM)-Pro, MM-Liberty, MM-Liberty Plus, MM-Defender, SkeeterVacARGARG(SV)-35, SV-27, Mosquito DeletoTM(MD)-2200, MD-2500, MT150-Power Trap, and two models of The Guardian Mosquito Traps (MK-01 and MK-12). All trap models except the SV-35, the SV-27, the MD-2500, and the MK-12 attracted significantly more females than males. The SV-35 was the most efficient trap, catching significantly more females than all the other models. The MD-2200 and MK-12 models were the least effective in catching either female or male sand flies. These data indicate that several models of propane combustion traps might be suitable substitutes for either CO2-baited or unbaited light traps for adult sand fly surveillance tools. One advantageous feature is the traps' ability to remain operational 24/7 for ca. 20 days on a single tank of propane. Additionally, the models that produce their own electricity to power the trap's fans have an important logistical advantage in field operations over light traps, which require daily battery exchange and charging.

Greater income from reducing methane emissions could substantially increase the number of livestock producers who would find it profitable to install methane digesters. Large-scale hog and dairy operations with lagoon manure management systems are likely to benefit most from a higher carbon price, which could have long-run structural implications for the livestock vendor.

Testing the hypothesis that predators destined for molecular gut-content analysis must be hand-collected to avoid cross-contamination AN - 879471819; 14376269 AB - Molecular gut-content analysis enables detection of arthropod predation with minimal disruption of ecosystem processes. Mass-collection methods, such as sweep-netting, vacuum sampling and foliage beating, could lead to regurgitation or rupturing of predators along with uneaten prey, thereby contaminating specimens and compromising resultant gut-content data. Proponents of this 'cross-contamination hypothesis' advocate hand-collection as the best way to avoid cross-contamination. However, hand-collection is inefficient when large samples are needed, as with most ecological research. We tested the cross-contamination hypothesis by setting out onto potato plants immature Coleomegilla maculata and Podisus maculiventris that had been fed larvae of either Leptinotarsa decemlineata or Leptinotarsa juncta, or unfed individuals of these predator species along with L. decemlineata larvae. The animals were then immediately re-collected, either by knocking them vigorously off the plants onto a beat cloth and capturing them en masse with an aspirator ('rough' treatment) or by hand-searching and collection with a brush ('best practice'). Collected predators were transferred in the field to individual vials of chilled ethanol and subsequently assayed by PCR for fragments of cytochrome oxidase I of L. decemlineata and L. juncta. Ten to 39 per cent of re-collected fed predators tested positive by PCR for DNA of both Leptinotarsa species, and 14-38% of re-collected unfed predators contained L. decemlineata DNA. Overall levels of cross-contamination in the rough (31%) and best-practice (11%) samples were statistically different and supported the cross-contamination hypothesis. A pilot study on eliminating external DNA contamination with bleach prior to DNA extraction and amplification gave promising results.

An isolate collected near Sivas, Turkey was released for classical biological control of yellow starthistle (YST), which is an invasive alien weed in California, USA. The fungus has been released throughout California, but long-term establishment rates are generally low, apparently because this ecotype is not well adapted to the climate where the weed is most invasive. Using a site with excellent establishment as a target, the Match Climates function in CLIMEX climate modeling software identified similar sites in and around the San Francisco Bay Area, east to the Central Valley and Sierra foothills, and along the coast of Southern California. Similar sites in other states include Walla Walla, Washington, Pendelton, Oregon and Salt Lake City, Utah. A Compare Locations model based primarily on experimentally measured temperature and humidity requirements of the rust produced similar results. Using Sacramento, California, which is in the center of YST distribution, as a target, the Match Climates function predicted that the best locations to search for rust accessions to use in California are near Tunis, Tunisia, Foggia, Italy, Khalkis, Greece, Kayseri, Turkey, and possibly Constantine, Algeria. This generally agrees with the prediction of a Compare Locations model based on the geographic distribution of YST in California. Climatic factors that limit the long-term establishment of the fungus are likely to be summer heat and/or dry stress and short dew periods.

AN - 872140419; 14933434 AB - Theoretical and empirical work has established a positive relationship between resource availability and habitat invasibility. For nonnative invasive annual grasses, similar to other invasive species, invader success has been tied most often to increased nitrogen (N) availability. These observations have led to the logical assumption that managing soils for low N availability will facilitate restoration of invasive plant-dominated systems. Although invasive annual grasses pose a serious threat to a number of perennial-dominated ecosystems worldwide, there has been no quantitative synthesis evaluating the degree to which soil N management may facilitate restoration efforts. We used meta-analysis to evaluate the degree to which soil N management impacts growth and competitive ability of annual and perennial grass seedlings. We then link our analysis to current theories of plant ecological strategies and community assembly to improve our ability to understand how soil N management may be used to restore annual grass-dominated communities. Across studies, annual grasses maintained higher growth rates and greater biomass and tiller production than perennials under low and high N availability. We found no evidence that lowering N availability fundamentally alters competitive interactions between annual and perennial grass seedlings. Competitive effects of annual neighbors on perennial targets were similar under low and high N availability. Moreover, in most cases perennials grown under competition in high-N soils produced more biomass than perennials grown under competition in low-N soils. While these findings counter current restoration and soil N management assumptions, these results are consistent with current plant ecological strategy and community assembly theory. Based on our results and these theories we argue that, in restoration scenarios in which the native plant community is being reassembled from seed, soil N management will have no direct positive effect on native plant establishment unless invasive plant propagule pools and priority effects are controlled the first growing season.

Organophosphate insecticides have predominantly been used against plant bugs in recent years due to the reduced efficacy of other insecticides. In this study, a biochemical approach was developed to survey enzymatic levels associated with organophosphate resistance levels in field populations of the tarnished plant bug. Forty-three populations were collected from the delta areas of Arkansas, Louisiana, and Mississippi. Three esterase substrates and one substrate each of glutathione S-transferase (GST) and acetylcholinesterase (AChE) were used to determine corresponding detoxification enzyme activities in different populations. Compared to a laboratory susceptible colony, increases up to 5.29-fold for esterase, 1.96-fold for GST, and 1.97-fold for AChE activities were detected in the field populations. In addition to the survey of enzyme activities among the populations, we also examined the susceptibility of major detoxification enzymes to several inhibitors which could be used in formulations to synergize insecticide toxicity against the target pests. As much as 52-76% of esterase, 72-98% of GST, and 93% of AChE activities were inhibited in vitro. Revealing variable esterase and GST activities among field populations may lead to a better understanding of resistance mechanisms in the tarnished plant bug. This study also reports effective suppression of detoxification enzymes which may be useful in future insecticide resistance management program for the tarnished plant bug and other Heteropteran pests on Bt crops.

This is possible if exposure pathways lead to pathogens at exposure that consistently have a small probability of causing illness. In this situation, the probability of illness will follow an approximately linear function of dose. Consequently, the predicted probability of illness per serving across all exposures is linear with respect to the expected value of dose. The majority of dose-response functions are approximately linear when the dose is low. Nevertheless, what constitutes "low" is dependent on the parameters of the dose-response function for a particular pathogen. In this study, a method is proposed to determine an upper bound of the exposure distribution for which the use of a linear dose-response function is acceptable. If this upper bound is substantially larger than the expected value of exposure doses, then a linear approximation for probability of illness is reasonable. If conditions are appropriate for using the linear dose-response approximation, for example, the expected value for exposure doses is two to three logs10 smaller than the upper bound of the linear portion of the dose-response function, then predicting the risk-reducing effectiveness of a proposed policy is trivial. Simple examples illustrate how this approximation can be used to inform policy decisions and improve an analyst's understanding of risk.

These measurements fill a gap in the existing scientific PM sub(2.5) observation database by providing a targeted wildfire-specific observation dataset. Four deployments occurred during various fire types including a managed-for-fuel-treatment wildfire complex, a wildfire complex, and two regional fire events. The maximum 24-h averaged values for each case were: 94.5 mu g/m super(3) (2005), 425 mu g/m super(3) (2006), 118 mu g/m super(3) (2007), and 247 mu g/m super(3) (2008). While these values are high, the diurnal concentration median and first quartile values remain below 35 and 10 mu g/m super(3), respectively. For all cases, the hourly diurnal patterns exhibit peak concentrations in the mid-morning and low concentrations in the mid-afternoon. Correlations between daily area actively burning and observed PM sub(2.5) concentrations were significant for all cases and concentration patterns were found to be similar by geographic location rather than by type of fire (single vs. region-wide). Multiple co-located monitor types, the Environmental Proof Beta Attenuation Monitor, which measures PM sub(2.5) concentrations using a beta-beam aimed at particulates collected on filter tape, and the E-SAMPLER and DataRAM, which both use nephelometry to measure PM sub(2.5) concentrations, showed statistically good agreement.

Groups for experimental infection included control (noninfected), oral (infected orally with M. avium subsp. paratuberculosis strain K-10), oral/DXM (pretreatment with dexamethasone before oral inoculation), intraperitoneal (i.p.) inoculation, and oral/M (oral inoculation with mucosal scrapings from a cow with clinical disease) groups. One of the earliest markers to emerge was antigen-specific gamma interferon (IFN-). Only i.p. inoculated calves had detectable antigen-specific IFN- responses at 7 days, with responses of the other infection groups becoming detectable at 90 and 120 days. All infection groups maintained robust IFN- responses for the remainder of the study. At 1 month, calves in the oral and oral/M groups had higher antigen-stimulated interleukin-10 (IL-10) levels than calves in the other treatment groups, but IL-10 secretion declined by 12 months for all calves. T-cell activation markers such as CD25, CD26, CD45RO, and CD5 were significantly upregulated in infected calves compared to noninfected controls. Oral inoculation of calves resulted in significantly increased antigen-specific lymphocyte proliferation at 9 and 12 months, as well as inducible nitric oxide synthase (iNOS) secretion at 6 and 12 months. These results demonstrate that infection of naieve calves with M. avium subsp. paratuberculosis invoked early immunologic responses characterized by robust antigen-specific IFN- responses and induction of CD25 and CD45RO expression on T-cell subsets.

It may be more appropriate to treat exotic plant infestations that still have some remaining native vegetation. We evaluated this restoration strategy by measuring the effects of spring burning, fall burning, fall applied imazapic, spring burning with fall applied imazapic, and fall burning with fall applied imazapic on the exotic annual grass, medusahead (Taeniatherum caput-medusae (L.) Nevski), and native vegetation at six sites in Oregon for 2 years post-treatment. Medusahead infestations included in this study had some residual native perennial bunchgrasses and forbs. Burning followed by imazapic application provided the best control of medusahead and resulted in the greatest increases in native perennial vegetation. However, imazapic application decreased native annual forb cover the first year post-treatment and density the first and second year post-treatment. The spring burn followed by imazapic application produced an almost 2-fold increase in plant species diversity compared to the control. The fall burn followed by imazapic application also increased diversity compared to the control. Results of this study indicate that native plants can be promoted in medusahead invasions; however, responses vary by plant functional group and treatment. Our results compared to previous research suggest that restoration of plant communities invaded by exotic annual grass may be more successful if efforts focus on areas with some residual native perennial vegetation. Thus, invasive plant infestations with some native vegetation remaining should receive priority for restoration efforts over near monocultures of invasive plant species.

These flavoring plant essential oil components are generally regarded as safe. Edible films made from fruits or vegetables containing apple skin polyphenols have the potential to be used commercially to protect food against contamination by pathogenic bacteria. The main objective of this study was to evaluate physical properties as well as antimicrobial activities againstListeria monocytogenes,Escherichia coliO157:H7, andSalmonella entericaof apple skin polyphenols at 0% to 10% (w/w) concentrations in apple puree film-forming solutions formulated into edible films. Commercial apple skin polyphenol powder had a water activity of 0.44 and high total soluble phenolic compounds and antioxidant capacity (995.3 mg chlorogenic acid/100 g and 14.4 mg Trolox/g, respectively). Antimicrobial activities of edible film containing apple skin polyphenols were determined by the overlay method. Apple edible film with apple skin polyphenols was highly effective againstL. monocytogenes. The minimum concentration need to inactiveL. monocytogeneswas 1.5%. However, apple skin polyphenols did not show any antimicrobial effect againstE. coliO157:H7 andS. entericaeven at 10% level. The presence of apple skin polyphenols reduced water vapor permeability of films. Apple skin polyphenols increased elongation of films and darkened the color of films. The results of the present study show that apple skin polyphenols can be used to prepare apple-based antimicrobial edible films with good physical properties for food applications by direct contact.

The sole population of about 500 birds is currently restricted to remote, higher elevation areas of the Alakai Plateau. Puaiohi nest primarily on steep streamside cliffs, and their distribution and abundance are limited by availability of suitable nesting sites. Black rats (Rattus rattus) cause nest failure and mortality of nesting female puaiohis, and ground-based rodent control has not been effective at reducing nest predation. In 2007, we investigated whether artificial nest structures might be a viable alternative to rodent control by testing nest-box designs to find one that was resistant to rats. In laboratory trials, we evaluated 3 designs that were currently being deployed as artificial nest boxes for puaiohi and found that they were not rat resistant. From these results, we developed and tested an improved design. Captive rats were unable to enter a nest box made from a 36-cm length of 15-cm-diameter plastic pipe with an overhanging entrance cut at an angle of 49 degree .

Currently, there is no data characterizing pigeon habitat use and movement patterns within and among commercial livestock facilities. To better understand the capacity for pigeons to spread pathogens, we used radio-telemetry techniques to estimate the home-range, travel distance, activity, and habitat use of pigeons roosting on and off dairies and feedlots in western Weld County, Colorado. Our observations suggest that pigeons roosting on (resident) and off (nonresident) livestock facilities use habitat differently. Nonresident pigeons used larger home-range areas than did resident pigeons. Nonresident pigeons traveled farther and frequented more livestock facilities than did resident pigeons. Both resident and nonresident pigeons disproportionally selected livestock facilities over other available foraging sites. We detected no difference in pigeon activities (i.e. loafing, feeding, drinking, flying) between resident and nonresident pigeons. Data suggest that nonresident pigeons may vector livestock pathogens among livestock facilities and resident pigeons may aid in the amplification and maintenance of pathogens within livestock facilities. Thus, targeted management of pigeons may help mitigate the introduction and maintenance of pathogens that cause disease and economic loss within livestock facilities.

There has been an increased food safety concern with this organism since outbreaks of human illnesses caused by this pathogen were first reported in 1982. Therefore, developing a reliable, sensitive, and rapid assay capable of detecting E. coli O157 and the main toxins produced by STEC (i.e., Shiga toxins 1 [Stx sub( 1)] and 2 [Stx sub( 2)]) will directly benefit regulatory agencies by minimizing analysis time. Here, we use Luminex technology to detect multiple analytes in a single 50-ml sample. Using commercially available monoclonal antibodies coupled to carboxylated magnetic microbeads, we developed an immunoassay capable of simultaneously serotyping E. coli O157 and detecting Stx sub( 1) and/or Stx sub( 2). The specificity and sensitivity of this immunoassay was tested against a collection of 34 E. coli isolates belonging to various O serogroups phenotypically different for Stx. The results were compared with microplate sandwich enzyme-linked immunosorbent assay (ELISA), and no cross-reactivity was observed for any of the monoclonal antibodies used. An increased sensitivity up to 1,000 times was observed in the microbead-based immunoassay when compared with the microplate sandwich ELISA. The results indicate that Luminex technology has the potential to simultaneously detect multiple targets without loss of specificity and/or sensitivity. A blind experiment was conducted with 48 samples of ground beef, lettuce, and milk spiked with less than or equal to 2 CFU/g E. coli. All the samples were correctly identified, with no false positives or false negatives. This microbead-based immunoassay could be extended to simultaneously detect additional foodborne pathogens and their toxic markers.

Modified river ecosystems frequently support invasive species to the detriment of native species. Rana catesbeiana (American bullfrog) is an invasive amphibian that thrives in modified aquatic habitats. In 2004-2005 we studied the distribution of bullfrogs along a 98-km reach of the Trinity River below the Lewiston Dam to identify habitat characteristics associated with bullfrogs and to recommend actions to reduce their prevalence in the system. We also examined native amphibian distributions relative to bullfrogs and disturbance regimes. We used regression techniques to model the distribution of bullfrogs in relation to environmental conditions. Models assessing breeding habitat outperformed models assessing bullfrog presence. Top-ranked predictor variables of bullfrog distribution included water depth, percent rooted floating vegetation, and river km. Most breeding sites of bullfrogs were relict mine tailing ponds or inactive side channels created during restoration activities in the 1990s. Native species were more common in the lower reach where habitats were less modified, in contrast to the distribution of bullfrogs that dominated the upper, more modified reach. To control bullfrogs along a managed river, we suggest reducing the suitability of breeding sites by decreasing depth or reducing hydroperiod and increasing connection with the active river channel. Current management goals of restoring salmonid habitat and returning the river to a more natural hydrologic condition should aid in control of bullfrogs and improve conditions for native amphibians.

In this study, we examined alterations to nutrient dynamics resulting from beetle herbivory in a Tamarix-invaded riparian ecosystem in the Great Basin Desert in northern Nevada, USA, by measuring changes in litter quality and decomposition, as well as changes in litter quantity. Generally, herbivory resulted in improved leaf litter chemical quality, including significantly increased nitrogen (N) and phosphorus (P) concentrations and decreased carbon (C) to nitrogen (C:N), C:P, N:P, and lignin:N ratios. Beetle-affected litter decomposed 23% faster than control litter, and released 16% more N and 60% more P during six months of decomposition, as compared to control litter. Both litter types showed a net release of N and P during decomposition. In addition, herbivory resulted in significant increases in annual rates of total aboveground litter and leaf litter production of 82% and 71%, respectively, under the Tamarix canopy. Our finding that increased rates of N and P release linked with an increased rate of mass loss during decomposition resulting from herbivore-induced increases in litter quality provides new support to the nutrient acceleration hypothesis. Moreover, results of this study demonstrate that the introduction of the northern tamarisk beetle as biological control to a Tamarix-invaded riparian ecosystem has lead to short-term stimulation of nutrient cycling. Alterations to nutrient dynamics could have implications for future plant community composition, and thus the potential for restoration of Tamarix-invaded ecosystems.

A procedure is also described to transfer lactic acid bacteria from frozen storage in MRS broth into cucumber juice and commercial jars of kosher dill cucumbers so that a selected strain of lactic acid bacteria can be kosher certified for commercial fermentations in processing plants that operate under kosher certification. The strain ofL. plantarumused in these experiments grew to maximum cell numbers in 4 d at 20 to 25 degree C and then maintained viable cell numbers for 2 wk at >108 CFU/mL so the culture was suitable for inoculation of fermentation tanks. Refrigeration of jars of culture after they grow to maximum numbers minimizes die-off of cells sufficiently so that a pure culture can be maintained by aseptically transferring brine containing viable bacteria to a new pH-adjusted jar only once every 4 mo. Practical Application: This report describes a method to prepare a lactic acid bacteria starter culture suitable for kosher vegetable fermentations.

Twelve strains of Leuconostoc citreum and L. mesenteroides that produce a variety of extracellular glucans were compared for their capacity to produce biofilms. 16s rRNA sequence analysis was used to confirm the species identity of these strains, which included four isolates of L. mesenteroides, five isolates of L. citreum, and three glucansucrase mutants of L. citreum strain NRRL B-1355. Strains identified as L.mesenteroides produce glucans that are generally similar to commercial dextran. Nevertheless, these strains differed widely in their capacity to form biofilms, with densities ranging from 2.7 to 6.1 logcfu/cm super(2). L. citreum strains and their derivatives produce a variety of glucans. These strains exhibited biofilm densities ranging from 2.5 to 5.9 logcfu/cm super(2). Thus, biofilm-forming capacity varied widely on a strain-specific basis in both species. The types of polysaccharides produced did not appear to affect the ability to form biofilms.

Methods and Results: Five Escherichia coli O157:H7 strains were evaluated for curli expression, hydrophobicity, biofilm formation and attachment to intact and cut fresh produce (cabbage, iceberg lettuce and Romaine lettuce) leaves. Biofilm formation was stronger when E. coli O157:H7 were grown in diluted tryptic soy broth (1:10). In general, strong curli-expressing E. coli O157:H7 strains 4406 and 4407 were more hydrophobic and attached to cabbage and iceberg lettuce surfaces at significantly higher numbers than other weak curli-expressing strains. Overall, E. coli O157:H7 populations attached to cabbage and lettuce (iceberg and Romaine) surfaces were similar (P>0.05), indicating produce surfaces did not affect (P0.05) in most cases. Escherichia coli O157:H7 attachment and attachment strength (SR) to intact and cut produce surfaces increased with time. Conclusions: Curli-producing E. coli O157:H7 strains attach at higher numbers to produce surfaces. Increased attachment of E. coli O157:H7 on cut surfaces emphasizes the need for an effective produce wash to kill E. coli O157:H7 on produce. Significance and Impact of the Study: Understanding the attachment mechanisms of E. coli O157:H7 to produce surfaces will aid in developing new intervention strategies to prevent produce outbreaks.

Methods and Results: Four-ounce glass jars were coated with a mixture of polylactic acid (PLA) polymer and antimicrobial compounds containing 100-500 mu l allyl isothiocyanate (AIT), 250mg nisin, 250mg zinc oxide nanoparticles per jar or their combinations. The coated jars contained 100ml of liquid egg white (LEW) inoculated with a three-strain Salmonella enterica ssp. enterica cocktail at populations of 103 or 107CFUml-1 and stored at 10 degree C for 28days. The PLA coating with 500 mu l AIT completely inactivated 3 and 7logCFUml-1 of Salmonella after 7 and 21days of storage, respectively. The PLA coating with 200 mu l AIT in combination with 250mg nisin reduced Salmonella populations to an undetectable level (<10CFUml-1) after 21days of storage. Conclusions: PLA coatings containing AIT alone or in combination with nisin effectively inactivated salmonellae in LEW. Significance and Impact of the Study: This study demonstrated the commercial potential of applying the antimicrobial bottle coating method to liquid eggs and possibly other fluid food products.

Copper desorption isotherms AN - 860383043; 14366569 AB - Contaminant desorption constrains the long-term effectiveness of remediation technologies, and is strongly influenced by dynamic non-equilibrium states of environmental and biological media. Information is currently lacking in the influence of biochar and activated carbon amendments on desorption of heavy metal contaminants from soil components. In this study, copper sorption-desorption isotherms were obtained for clay-rich, alkaline San Joaquin soil with significant heavy metal sorption capacity, and eroded, acidic Norfolk sandy loam soil having low capacity to retain copper. Acidic pecan shell-derived activated carbon and basic broiler litter biochar were employed in desorption experiments designed to address both leaching by rainfall and toxicity characteristics. For desorption in synthetic rain water, broiler litter biochar amendment diminished sorption-desorption hysteresis. In acetate buffer (pH 4.9), significant copper leaching was observed, unless acidic activated carbon (pHpzc =3.07) was present. Trends observed in soluble phosphorus and zinc concentrations for sorption and desorption equilibria suggested acid dissolution of particulate phases that can result in a concurrent release of copper and other sorbed elements. In contrast, sulfur and potassium became depleted as a result of supernatant replacements only when amended carbon (broiler litter biochar) or soil (San Joaquin) contained appreciable amounts. A positive correlation was observed between the equilibrium aluminum concentration and initial copper concentration in soils amended with acidic activated carbon but not basic biochar, suggesting the importance of cation exchange mechanism, while dissolution of aluminum oxides cannot be ruled out.

Copper sorption isotherms and the release of cations AN - 860382818; 14366568 AB - The amendment of carbonaceous materials such as biochars and activated carbons is a promising in situ remediation strategy for both organic and inorganic contaminants in soils and sediments. Mechanistic understandings in sorption of heavy metals on amended soil are necessary for appropriate selection and application of carbonaceous materials for heavy metal sequestration in specific soil types. In this study, copper sorption isotherms were obtained for soils having distinct characteristics: clay-rich, alkaline San Joaquin soil with significant heavy metal sorption capacity, and eroded, acidic Norfolk sandy loam soil having low capacity to retain copper. The amendment of acidic pecan shell-derived activated carbon and basic broiler litter biochar lead to a greater enhancement of copper sorption in Norfolk soil than in San Joaquin soil. In Norfolk soil, the amendment of acidic activated carbon enhanced copper sorption primarily via cation exchange mechanism, i.e., release of proton, calcium, and aluminum, while acid dissolution of aluminum cannot be ruled out. For San Joaquin soil, enhanced copper retention by biochar amendment likely resulted from the following additional mechanisms: electrostatic interactions between copper and negatively charged soil and biochar surfaces, sorption on mineral (ash) components, complexation of copper by surface functional groups and delocalized Ie electrons of carbonaceous materials, and precipitation. Influence of biochar on the release of additional elements (e.g., Al, Ca) must be carefully considered when used as a soil amendment to sequester heavy metals.

Six isolates were tested for parasitic and antimicrobial activity against P. capsici and for endophytic and induced resistance capabilities in pepper. Isolates DIS 70a, DIS 219b, and DIS 376f were P. capsici parasites, while DIS 70a, DIS 259j, DIS 320c, and DIS 376f metabolites inhibited P. capsici. All six isolates colonized roots but were inefficient stem colonizers. DIS 259j, DIS 320c, and DIS 376f induced defense-related expressed sequence tags (EST) in 32-day-old peppers. DIS 70a, DIS 259j, and DIS 376f delayed disease development. Initial colonization of roots by DIS 259j or DIS 376f induced EST with potential to impact Trichoderma endophytic colonization and disease development, including multiple lipid transferase protein (LTP)-like family members. The timing and intensity of induction varied between isolates. Expression of CaLTP-N, encoding a LTP-like protein in pepper, in N. benthamiana leaves reduced disease development in response to P. nicotianae inoculation, suggesting LTP are functional components of resistance induced by Trichoderma species. Trichoderma isolates were endophytic on pepper roots in which, depending on the isolate, they delayed disease development by P. capsici and induced strong and divergent defense reactions.

Despite the long history of such work, confirmation of these phenomena and a determination of the underlying mechanisms remain elusive. Here, we revisited these questions using modern imaging technologies to study the susceptibility of Nicotiana benthamiana to Turnip mosaic virus (TuMV). We found that both light deficiency and photosystem impairment increased the susceptibility of N. benthamiana to TuMV infection. Time-lapse photography studies indicated that, under these conditions, rub-inoculated plants exhibited greater numbers of infection foci and more rapid foci development. The rate of systemic movement was also accelerated though cell-to-cell movement appeared unchanged. Inhibition of salicylic acid (SA)-mediated defense responses is not likely responsible for changes in susceptibility because SA and pathogen response-1 gene induction were not affected by light deficiency or chloroplast impairment and treatment of plants with SA had no measureable impact on TuMV infection. Taken together, these data suggest that both light and optimal chloroplast function influence virus infection either by limiting the cellular resources needed by TuMV to establish replication complexes or the host's ability to activate SA-independent defenses.

Campylobacter spp. exist as commensal organisms in some animal species, yet are estimated to be the most common causative agents of foodborne illness in humans. C. jejuni is most often associated with poultry, while C. coli are more frequently associated with swine. Temperature has been suggested to trigger potential colonization or virulence factors in C. jejuni, and recent studies have demonstrated temperature-dependent genes are important to colonization. It is possible that temperature-dependent colonization factors are in part responsible for the species-specific colonization characteristics of C. coli also. We determined utilization of 190 different sole carbon substrates by C. coli ATCC 49941 at 37 and 42 degree C using phenotype microarray (PM) technology. Temperature did affect amino acid utilization. l-asparagine and l-serine allowed significantly (P=0.004) more respiration by C. coli ATCC 49941 at the lower temperature of 37 degree C as compared to 42 degree C. Conversely, l-glutamine was utilized to a significantly greater extent (P=0.015) at the higher temperature of 42 degree C. Other organic substrates exhibited temperature-dependent utilization including succinate, d,l-malate, and propionate which all supported active respiration by C. coli to a significantly greater extent at 42 degree C. Further investigation is needed to determine the basis for the temperature-dependent utilization of substrates by Campylobacter spp. and their possible role in species-specific colonization.

For a century, the network of experimental forests have contributed immensely--both in the US and around the world--to the practical understanding of the environment and to the formation of management approaches and policies that affect our use of forests and the natural resources they contain. Experimental forests provide places for long-term science and management studies in major vegetation types across the 789,140km2 of public land administered by the Forest Service. They also provide an incredible wealth of records and knowledge of environmental change in natural and managed forest ecosystems across the United States. Pringle Falls Experimental Forest (Pringle Falls), southwest of Bend, Oregon, is the oldest experimental forest in the Pacific Northwest and is the site of some of the earliest forest management and silviculture research in this region. Research at this site began in 1914, and it was formally established as part of the national network of experimental forests in 1931 as a center for silviculture, forest management, and insect and disease research in ponderosa pine forests east of the Oregon Cascade Range. As part of the celebration of the Centennial Anniversary of the network of experimental forests, it is timely to examine a few of the ecological lessons that have resulted from long-term studies at Pringle Falls. Two different yet interconnected themes are traced: (1) management of existing old-growth ponderosa pine; and (2) management of young or immature ponderosa pine. Examples of ecological lessons, drawn from long-term studies established or followed by James W. Barrett, Matt D. Busse, Patrick H. Cochran, Walter G. Dahms, F. Paul Keen, Ernest L. Kolbe, Edwin L. Mowat, William W. Oliver, Ram Oren, Chester T. Youngberg, and Jianwei Zhang illustrate how work at Pringle Falls has both pursued and influenced societal demands for forest management strategies, and how this trajectory has cycled back to the themes under which the experimental forest was first established. Finally, these two themes are integrated as drivers for new landscape-scale long-term research at Pringle Falls, designed to evaluate the effects of thinning and fuel reduction treatments on multiple, interacting forest stresses of fire, insects, wind, and climate change.

AN - 860381296; 14363999 AB - The Crossett Experimental Forest was established in 1934 to provide landowners in the Upper West Gulf Coastal Plain with reliable, science-based advice on how to manage their loblolly (Pinus taeda) and shortleaf (Pinus echinata) pine-dominated forests. A key component of this program was the establishment of an unmanaged control, currently known as the Russell R. Reynolds Research Natural Area (RRNA). Originally intended to show how the lack of regulation reduced sawtimber production compared to more intensively managed stands, the once-cut RRNA is now recognized as an increasingly scarce example of an undisturbed, mature pine-hardwood stand. This, in turn, has led to studies on forest succession, coarse woody debris, old-growth stand structure conditions, and biomass accumulation patterns. Long-term (72 years, to date) research has shown, as an example, that the RRNA has sustained >33m2 of basal area and over 240Mg of aboveground live tree biomass per hectare for decades, values that are near the upper end of temperate forest ecosystems (outside of rainforests). These high levels are made possible by the abundance of large pines; however, pine mortality and natural successional patterns in this undisturbed stand will likely result in declining biomass in the near future. Additional work is possible regarding endangered species habitat and paleoclimate change, and there is potential for studies on invasive species effects on mature, unmanaged forests. Monitoring will continue indefinitely on the RRNA. JF - Forest Ecology and Management AU - Bragg, Don C AU - Shelton, Michael G AD - USDA Forest Service, Southern Research Station, P.O.

AN - 853995606; 21306148 AB - In situ and in vitro experiments were performed to assess the effects of solar radiation and predation by indigenous microflora on the relative die-off rates of a toxigenic strain of Escherichia coli O157:H7, commensal E. coli, and fecal enterococci in surface waters from ponds in agricultural watersheds. The objective of these experiments was to discern a mechanism of persistence of E. coli O157:H7 in surface waters compared to fecal indicator bacteria. Results of these experiments indicated that E. coli and fecal enterococci were affected by both insolation and apparent predation; whereas E. coli O157:H7 appeared to be resistant to both of these environmental stressors. The number of days to reach 99% die-off (T(99)-values) for E. coli O157:H7 was significantly greater than that for the indicator bacteria. The capacity to prolong die-off may be connected to the apparent persistence of E. coli O157:H7 in surface waters.

IFN- gamma and IL-4 are the hallmark T sub(H)1 and T sub(H)2 cytokines, respectively. In avian species, information concerning regulation of macrophage activity by T sub(H)1/2 cytokines is limited. Here, we investigated the regulatory function of chicken T sub(H)1 cytokines IFN- gamma , IL-18 and T sub(H)2 cytokines IL-4, IL-10 on the HD11 macrophage cell line. Chicken IFN- gamma stimulated nitric oxide (NO) synthesis in HD11 cells and primed the cells to produce significantly greater amounts of NO when exposed to microbial agonists, lipopolysaccharide, lipoteichoic acid, peptidoglycan, CpG-ODN, and poly I:C. In contrast, chicken IL-4 exhibited bi-directional immune regulatory activity: it activated macrophage NO synthesis in the absence of inflammatory agonists, but inhibited NO production by macrophages in response to microbial agonists. Both IFN- gamma and IL-4, however, enhanced oxidative burst activity of the HD11 cells when exposed to Salmonella enteritidis. IL-18 and IL-10 did not affect NO production nor oxidative burst in HD11 cells. Phagocytosis and bacterial killing by the HD11 cells were not affected by the treatments of these cytokines. Infection of HD11 cells with S. enteritidis was shown to completely abolish NO production regardless of IFN- gamma treatment. This study has demonstrated that IFN- gamma and IL-4 are important T sub(H)1 and T sub(H)2 cytokines that regulate macrophage function in chickens.

AN - 853226051; 20799276 AB - Swainsonine, a polyhydroxy indolizidine alkaloid and known glycosidase inhibitor, is found in a number of different plants that cause a lysosomal storage disease known as locoism in the western USA. Most recently swainsonine has been analysed by LC-MS/MS after sample extraction and preparation from ion-exchange resins. To compare previously published sample preparation procedures with several new alternative procedures to provide methods using either commercially available solid-phase extraction equipment or procedures which significantly reduce sample preparation time. A previously reported and validated sample preparation method using ion-exchange resin was compared with methods using a commercially available solid-phase extraction cartridge, a solvent partitioning procedure or a single solvent extraction procedure using one of two solvents. Twenty different plant samples of varying swainsonine concentrations were prepared in triplicate and analysed by LC-MS/MS. The measured concentration of swainsonine was then statistically compared between methods. There were no statistically significant differences found between four of the five different sample preparation methods tested. A commercially available SPE cartridge can be used to replace the previously used ion-exchange resin for swainsonine analysis. For very rapid analyses the SPE procedure can be eliminated and a simple, single solvent extraction step used for sample preparation. Copyright © 2010 John Wiley & Sons, Ltd.

AN - 848319494; 21176854 AB - Feral swine (Sus scrofa) pose a significant disease threat to livestock and humans. Emerging technologies to reduce feral swine disease transmission risks include fertility control, vaccination, and toxicants. However, for these technologies to be appropriate for field application, a feral swine-specific oral delivery system is needed. We used two field trials to generate information related to appropriate field application of the Boar-Operated-System (BOSâ„¢), an oral delivery system designed to provide bait access only to feral swine. Our objectives were to determine whether pre-baiting BOSâ„¢ units increased bait removal and to evaluate the proportion of feral swine and non-target animals that ingest baits designed to deliver pharmaceuticals through the BOSâ„¢. During both trials we used baits housed within 10 BOSâ„¢ units. We monitored wildlife visitation, bait removal, and ingestion using motion sensing digital photography and baits containing the bait marker tetracycline hydrochloride (TH). During trial 1 we found three of five pre-baited BOSâ„¢ units were used by feral swine only. Additionally, we found the five BOSâ„¢ units that were not pre-baited were not used by feral swine or non-target wildlife. During trial 2 we determined bait removal from the BOSâ„¢ to be reduced by only 10% for feral swine when activated, whereas bait removal from the BOSâ„¢ by all other wildlife was reduced by 100% when activated. We captured 81 feral swine and 23 raccoons and found 90% and 13% to have TH-marked teeth, respectively. With minor modifications, the BOSâ„¢ should be considered a valuable tool to be used in feral swine disease management in conjunction with existing technologies. Published by Elsevier B.V.

To help balance these multiple demands, our objectives were to (1) determine height distribution of corn stover biomass, (2) quantify the percentage of stover that is corn cob, and (3) develop a general relationship between plant harvest height and stover remaining in the field for a broad range of growing conditions, soil types, and hybrids in different regions. Plant height, dry grain, stover, and cob yield data were collected at eight US locations. Overall, stover yield increased about 0.85Mgha super(-1) and cob yield increased about 0.10Mgha super(-1) for each 1.0Mgha super(-1) increase in dry grain yield. At grain harvest, the stover-to-grain ratio ranged from 0.64 to 0.96 and cob-to-grain ratio ranged from 0.11 to 0.19. A strong nearly 1:1 linear (r super(2)=0.93) relationship between the relative cutting height and relative biomass remaining in the field was observed across all sites. These data were requested by the US Department of Agriculture-Natural Resource Conservation Service to help improve version 2 of the Revised Universal Soil Loss Equation (RUSLE2) and Wind Erosion Prediction System and better estimate corn stover harvest rates based on cutting height or selective organ harvest (e.g., grain and cob only). This information will improve the capacity of RUSLE2 and similar models to predict the erosion risk associated with harvesting corn residues.

We recognize that at present, such a review remains, in part, speculative, and more illustrative than definitive. However, recent events on the global stage, particularly in regard to the number of food riots that occurred during 2008, even at a time of record harvests, have prompted additional interest in those factors, including invasive species, which could, through climatic uncertainty, alter food production. To that end, as agricultural scientists, we wish to begin an initial evaluation of key questions related to food production and climate change including: how vulnerable is agriculture to invasive species?; are current pest management strategies sufficient to control invasive outbreaks in the future?; what are the knowledge gaps?; can we provide initial recommendations for scientists, land managers and policy makers in regard to available resources? Our overall goals are to begin a synthesis of potential impacts on productivity, to identify seminal research areas that can be addressed in future research, and to provide the scientific basis to allow agronomists and land managers to formulate mitigation and adaptation options regarding invasive species and climate change as a means to maintain food security.

(Pinon-juniper) woodlands of the western United States have expanded in area nearly 10-fold since the late 1800's. Juniperus occidentalis ssp. occidentalis Hook. (western juniper) dominance in sagebrush steppe has several negative consequences, including reductions in herbaceous production and diversity, decreased wildlife habitat, and higher erosion and runoff potentials. Prescribed fire and mechanical tree removal are the main methods used to control J. occidentalis and restore sagebrush steppe. However, mature woodlands become difficult to prescribe burn because of the lack of understory fuels. We evaluated partial cutting of the woodlands (cutting 25-50% of the trees) to increase surface fuels, followed by prescribed fire treatments in late successional J. occidentalis woodlands of southwest Idaho to assess understory recovery. The study was conducted in two different plant associations and evaluated what percentage of the woodland required preparatory cutting to eliminate remaining J. occidentalis by prescribed fire, determined the impacts of fire to understory species, and examined early post-fire successional dynamics. The study demonstrated that late successional J. occidentalis woodlands can be burned after pre-cutting only a portion of the trees. Early succession in the cut-and-burn treatments were dominated by native annual and perennial forbs, in part due to high mortality of perennial bunchgrasses. By the third year after fire the number of establishing perennial grass seedlings indicated that both associations would achieve full herbaceous recovery. Cutting-prescribed fire combinations are an effective means for controlling encroaching late successional J. occidentalis and restoring herbaceous plant communities. However, land managers should recognize that there are potential problems associated with cutting-prescribed fire applications when invasive weeds are present.

However, planning for reservoir flushing or dam removal requires knowledge of these interactions. In both cases, impounded sediments are introduced to channel beds that have had fine sediment particles removed without replacement. The channel bed pore space interacts with the flow and provides storage for particles. In order to address the need for information on such systems, an adjustable-slope, recirculating laboratory flume was used to study the changes in flow and turbulence caused by sand added to an immobile gravel bed. Detailed measurements were made using an acoustic Doppler velocimeter that collected three velocity components at a rate of 200 Hz. Because of the rough nature of the bed, individual velocity profiles varied significantly; therefore, in order to determine general trends, the data were spatially averaged over six 10 20 cm planes parallel to the bed with the lowest plane about 2 cm below the maximum gravel elevation. The increasing elevation of sand relative to the gravel layer resulted in decreased bed shear stress, decreased Reynolds stress, increased relative turbulence intensity, and a near-bed shift toward sweep-dominated turbulence.

Ionizing irradiation is a promising phytosanitary treatment that is increasing in use worldwide. Almost 19000 metric tons of sweet potatoes and several fruits plus a small amount of curry leaf are irradiated each year in 6 countries, including the United States, to control a number of plant quarantine pests. Advantages over other treatments include tolerance by most fresh commodities, ability to treat in the final packaging and in pallet loads, and absence of pesticide residues. Disadvantages include lack of acceptance by the organic food industries and logistical bottlenecks resulting from current limited availability of the technology. A regulatory disadvantage is lack of an independent verification of treatment efficacy because pests may be found alive during commodity inspection, although they will not complete development or reproduce. For phytosanitary treatments besides irradiation, the pests die shortly after the treatment is concluded. This disadvantage does not hamper its use by industry, but rather makes the treatment more difficult to develop and regulate. Challenges to increase the use of phytosanitary irradiation (PI) are cost, because commercial use has not yet reached an optimum economy of scale, lack of facilities, because of their cost and current inability to feasibly locate them in packing facilities, lack of approved treatments for some quarantine pests, and concern about the process by key decision makers, such as packers, shippers, and retailers. Methods for overcoming these challenges are discussed. JF - Comprehensive Reviews in Food Science and Food Safety AU - Hallman, Guy J AD - Author Hallman is with USDA-ARS, 2413 E.

This cultivar currently accounts for about 70% of Hawaii's papaya acreage. The nutritional composition of Rainbow papaya and a non-transgenic control were analyzed to address GE food safety concerns regarding the potential for altered nutritional composition and altered expression of inherent allergens and toxic proteins. Rainbow papaya fruit were analyzed at three ripening stages and the data compared to that of a non-transgenic papaya which shares a similar pedigree. No differences were observed between GE and non-GE papaya for 36 nutrients at any of the tested fruit ripeness stages. However, vitamin A was higher and calcium levels were lower in the GE fruit. The GE fruit showed higher levels of protein and papain at the earliest stage of ripening (color break), but in ripened fruit these differences were insignificant. Benzyl isothiocyanate (BITC) levels were very low and similar for both Rainbow and the non-transgenic control fruit at all ripeness stages. Our data show that the contents of nutrients, BITC and papain of GE Rainbow papaya are within the range of those of non-GE papaya and that the Rainbow cultivar is substantially similar to the non-GE cultivar.

Currently, a majority of commercial sweet corn fields suffer losses due to weeds, despite widespread use of atrazine. Field experiments were conducted in the primary North American production areas of sweet corn grown for processing to determine the implications of further reductions in atrazine use on weed control and crop yield. A range of atrazine doses (0-1120 g ha super(-1)) applied postemergence with tembotrione (31 g ha super(-1)) were tested in two hybrids differing in canopy architecture and competitive ability with weeds. Atrazine applied postemergence reduced risk (i.e. more variable outcomes) of poor herbicide performance. Atrazine doses up to 1120 g ha super(-1) with tembotrione improved grass control and broadleaf weed control in five of eight and seven of eight environments, respectively. Of the three environments which had particularly low broadleaf weed control (<50%) with tembotrione alone, sweet corn yield was improved with atrazine. Hybrid 'Code128' produced a taller, denser canopy which was more efficient at capturing light and competing with weeds than 'Quickie'. As a result, greater crop competitiveness decreased risk of incomplete weed control as atrazine dose was reduced. Atrazine's contribution to weed control and yield protection was greatest when other aspects of weed management resulted in poor weed control. Should atrazine use be further restricted or banned altogether, this research demonstrates the importance of improving other aspects of weed management systems such as herbicidal and non-chemical tactics.

Since production fields with water repellent soil often contain areas of wettable soil, surfactants applied to such fields worldwide will likely be applied to wettable soil, with unknown consequences for irrigation-induced erosion, runoff, or soil water relations. We evaluated surfactant and simulated sprinkler irrigation effects on these responses for three wettable, Pacific Northwest soils, Latahco and Rad silt loams, and Quincy sand. Along with an untreated control, we studied three surfactants: an alkyl polyglycoside (APG) in solution at a concentration of 18 g active ingredient (AI) kg-1, a block copolymer at 26 g kg-1, and a blend of the two at 43 g kg-1. From 2005 to 2009 in the laboratory, each surfactant was sprayed at a rate of 46?8 l ha-1 onto each soil packed by tamping into 1?2- by 1?5-m steel boxes. Thereafter, each treated soil was irrigated twice at 88 mm h-1 with surfactant-free well water. After each irrigation, runoff and sediment loss were measured and soil samples were collected. While measured properties differed among soils and irrigations, surfactants had no effect on runoff, sediment loss, splash loss, or tension infiltration, compared to the control. Across all soils, however, the APG increased volumetric water contents by about 3% (significant at p= 15 ?m. All told, surfactants applied at economic rates to these wettable Pacific Northwest soils posed little risk of increasing either runoff or erosion or harming soil water relations. Moreover, by increasing water retention at high potentials, surfactants applied to wettable soils may allow water containing pesticides or other agricultural chemicals to better penetrate soil pores, thereby increasing the efficacy of the co-applied materials.

AN - 852540007; 21214242 AB - Locoweeds are defined as Astragalus and Oxytropis species that induce locoism due to the toxic alkaloid swainsonine. Swainsonine was detected in all parts of Astragalus lentiginosus and Astragalus mollissimus , with greater concentrations found in the aboveground parts. Undifilum oxytropis , a fungal endophyte responsible for the synthesis of swainsonine, was detected in all plant parts of A. lentiginosus and A. mollissimus. The amount of endophyte within a plant part does not always correspond to the concentration of swainsonine in the same part. Plants of A. mollissimus and A. lentiginosus can be divided into two chemotypes: those that contain swainsonine (>0.1%; chemotype 1) and those that contain little or no detectable swainsonine (<0.01%; chemotype 2). Chemotype 1 plants in both species had quantitatively higher amounts of endophyte compared to chemotype 2 plants. Swainsonine and endophyte amounts were not uniformly distributed within stalks of the same plant. For that reason, repeated sampling of stalks from the same plant during one growing season may provide misleading results. Sequence variants of U. oxytropis exist within populations of A. mollissimus, A. lentiginosus, and Oxytropis sericea and do not correlate with chemotype. These findings suggest several possible reasons for differential concentrations of swainsonine that will be tested in future work.

LiDAR-derived height profiles were also generated in 1-m layers, and regressed on CBD estimates calculated for 1-m layers from field plots to predict three-dimensional canopy fuel loading. We then produced maps of canopy fuel metrics for three 9km2 forested areas in the Pinelands. Correlations for standard LiDAR-derived parameters between the two LiDAR systems were all highly significant, with correlation coefficients ranging between 0.82 and 0.98. Stepwise linear regression models developed from the profiling LiDAR data predicted maximum CBD and CFW (r 2 =0.94 and 0.92) better than those developed from the scanning LiDAR data (r 2 =0.83 and 0.71, respectively). A single regression for the prediction of CBD at all canopy layers had r 2 values of 0.93 and 0.82 for the profiling and scanning datasets, respectively. Individual bin regressions for predicting CBD at each canopy height layer were also highly significant at most canopy heights, with r 2 values for each layer ranging between 0.36 and 0.89, and 0.44 and 0.99 for the profiling and scanning datasets, respectively. Relationships were poorest mid-canopy, where highest average values and highest variability in fuel loading occurred. Fit of data to Gaussian distributions of canopy height profiles facilitated a simpler expression of these parameters for analysis and mapping purposes, with overall r 2 values of 0.86 and 0.92 for the profiling and scanning LiDAR datasets, respectively. Our research demonstrates that LiDAR data can be used to generate accurate, three-dimensional representations of canopy structure and fuel loading at high spatial resolution by linking 1-m return height profiles to biometric estimates from field plots.

Costly equipment modifications make narrow rows impractical, but a twin-row configuration may boost production with fewer equipment modifications. Four field experiments were conducted to measure weed biomass, leaf area index (LAI), and yield for a conventional (CN) and a glyphosate-resistant (GR) hybrid across three plant densities (low 4.0-4.4 plants m super(-2); medium 5.9-6.4 plants m super(-2); and high 7.9-8.4 plants m super(-2)) and two row configurations (single vs. twin) in a conservation tillage system during the 2005 growing season. The experimental design was a split-split plot with a RCB arrangement of whole plots where hybrids were assigned to main plots, row configurations to subplots, and plant density to sub-subplots with four replications. Row configuration had little effect on weed biomass compared to plant density and hybrid. Leaf area index increased with higher plant density at all locations. In general, LAI increased with the twin-row configuration, but LAI also varied with hybrid based on interactions between hybrid and plant density or row configuration. Row configuration had little impact on maize yields, while plant density had the most effect on yields. Plant density also interacted with hybrid or row configuration at multiple locations, although maize yields did not always increase with higher plant density. Conventional hybrids may also provide an alternative to GR hybrids, particularly at lower plant densities. Maize yield increases with twin rows were minimal and may not justify twin row conversion under dryland conditions, but growers that already utilize twin-row equipment will not suffer yield decreases by planting twin rows.

Dispersing livestock from the heavily grazed regions is a central challenge in grazing land management. Position data gathered from GPS-collared livestock hold potential for increasing knowledge of factors driving livestock aggregation patterns, but advances in gathering the data have outpaced advancements in analyzing and learning from it. We fit a hierarchical seemingly unrelated regression (SUR) model to explore how season of stocking and the location where cattle entered a pasture influenced grazing distributions. Stocking alternated between summer on one side of the pasture one year and fall on another side of the pasture the next year for 18 years. Waypoints were recorded on cattle for 50d each year. We focused our analysis on the pasture's 10 most heavily grazed 4-ha units, because these units were the most prone to negative grazing impacts. Though grazing of the study units was always disproportionately heavy, it was much heavier with the summer than fall stocking regime: Bayesian confidence intervals indicate summer grazing of study units was approximately double the average fall grazing value. This is our core result, and it illustrates the strong effect stocking season or date or both can have on grazing distributions. We fit three additional models to explore the relative importance of stocking season versus location. According to this analysis, stocking season played a role, but stocking location was the main driver. Ostensibly minor factors (e.g. stocking location) can greatly influence livestock distributions.

Prediction of fire behavior in tree crowns is essential to informed decisions in fire management. Current methods used in fire management do not address variability in crown fuels. New mechanistic physics-based fire models address convective heat transfer with computational fluid dynamics (CFD) and can be used to model fire in heterogeneous crown fuels. However, the potential impacts of variability in crown fuels on fire behavior have not yet been explored. In this study we describe a new model, FUEL3D, which incorporates the pipe model theory (PMT) and a simple 3D recursive branching approach to model the distribution of fuel within individual tree crowns. FUEL3D uses forest inventory data as inputs, and stochastically retains geometric variability observed in field data. We investigate the effects of crown fuel heterogeneity on fire behavior with a CFD fire model by simulating fire under a homogeneous tree crown and a heterogeneous tree crown modeled with FUEL3D, using two different levels of surface fire intensity. Model output is used to estimate the probability of tree mortality, linking fire behavior and fire effects at the scale of an individual tree. We discovered that variability within a tree crown altered the timing, magnitude and dynamics of how fire burned through the crown; effects varied with surface fire intensity. In the lower surface fire intensity case, the heterogeneous tree crown barely ignited and would likely survive, while the homogeneous tree had nearly 80% fuel consumption and an order of magnitude difference in total net radiative heat transfer. In the higher surface fire intensity case, both cases burned readily. Differences for the homogeneous tree between the two surface fire intensity cases were minimal but were dramatic for the heterogeneous tree. These results suggest that heterogeneity within the crown causes more conditional, threshold-like interactions with fire. We conclude with discussion of implications for fire behavior modeling and fire ecology.

To help circumvent this limitation, the Yarrowia lipolytica lipase 2 (LIP2) gene was cloned into S. cerevisiae expression vectors and used to generate S. cerevisiae strains that secrete active Lip2 lipase (Lip2p) enzyme into the growth media. Specifically, LIP2 expression was driven by the S. cerevisiae PEX11 promoter, which maintains basal transgene expression levels in the presence of sugars in the culture medium but is rapidly upregulated by fatty acids. Northern blotting, lipase enzyme activity assays, and gas chromatographic measurements of cellular fatty acid composition after lipid feeding all confirmed that cells transformed with the PEX11 promoter-LIP2 construct were responsive to lipids in the media, i.e., cells expressing LIP2 responded rapidly to either free fatty acids or TAGs and accumulated high levels of the corresponding fatty acids in intracellular lipids. These data provided evidence of the creation of a self-regulating positive control feedback loop that allows the cells to upregulate Lip2p production only when lipids are present in the media. Regulated, autonomous production of extracellular lipase activity is a necessary step towards the generation of yeast strains that can serve as biocatalysts for conversion of low-value lipids to value-added TAGs and other novel lipid products.

AND MYJAVSKA PAHORKATINA UPLAND AN - 920808898; 16292396 AB - This study investigates the relationship between soil water repellency (SWR), soil temperature and some physical and chemical characteristics of soils belonging to five reference soil groups in the area of White Carpathian Mts. and Myjavska pahorkatina Upland. Samples (0-20 cm) were collected from forest soils exhibiting some degree of water repellency. Persistence of SWR was measured by commonly used water drop penetration time (WDPT) test and the severity of SWR by molarity of an ethanol droplet (MED) test. A heating experiment was designed in order to simulate conditions that normally occur in nature and are favourable for the change of SWR in soils. From the results it follows that heating at 50 degree C for the first three days caused in most soils a gradual decrease in MED values. Initial MED values were re-established only after soil heating at 150 degree C. This means that input of thermal energy was necessary to re-organize organic molecules causing SWR. In terms of comparison the MED values measured on air-dried and heated soils, the samples of rendzic Leptosols and Cambisol calcaric showed a decrease or no change in SWR, while SWR increased or exerted no change in samples of cambic Leptosols, whereas it solely intensified in haplic Leptosols and stagnic Cambisols. Luvisols and haplic Cambisols had a comparable portion of samples with increased and decreased final MED values.

When compared with control, the presence of selenite influenced the pH values of culture media, while the weight of biomass was not changed significantly. The concentration of selenite in culture media decreased rapidly on the 10th day of cultivation from initial concentration 19 and 27 mg.L super(-1) to 1.07 and 1.26 mg.L super(-1), respectively. However, the concentration of total selenium did not change during the 25-day cultivation significantly. While the accumulation of selenium on the 25th day of cultivation was negligible, almost all of uptaken selenium by fungus was transformed into volatile derivatives (up to 21% of initial selenite content in culture media). The removal of selenite from its aqueous solution by fungal biomass of A. niger is rapid, since the equilibrium was achieved after 20 min. However, biosorption capacity of fungal biomass for selenite removal is negligible (0.084 mg.g super(-1)) and not sufficient for possible remediation application.

For growth inhibition the following ranks orders were arranged: for roots Cr(VI) greater than or equal to Ni(II) >> Cr(III); for shoots Ni(II) > Cr(VI) >> Cr(III). When the relationship between dry (DM) and fresh (FM) mass was determined, the DM fraction was increased parallel with increased metal concentrations in order Cr(VI) > Ni(II) > Cr(III). This indicates a reduction in water uptake. Water content was reduced in all cases very rapidly, mainly in the roots and obtained results indicated that Cr and Ni inhibited water absorption by the roots, but not water translocation into the upper plant parts. The strongest unfavorable effect on the production of photosynthetic pigments had again Cr(VI) and the lowest Cr(III). Metals reduced more Chi a than Chi b production and their effect on carotenoids was mostly stimulative. Accumulation of all tested metals was higher in the roots and because transfer factor (TF) was lowers than 1, the transport of Cr and Ni from roots to shoots was restricted.

However, these fumigants also can have negative environmental and human health consequences and considerable research has been conducted on methods to minimize emission of these products from the soil to the atmosphere. To ensure that pest control efficacy is not compromised by emission reduction techniques, this research was conducted to simultaneously evaluate the effects of several surface seal techniques on fumigant emissions and the efficacy of soil-borne pest control with a mixture of 1,3-dichloropropene + chloropicrin. Results indicated that the interaction between emission reduction techniques and pest control efficacy can be complicated. For example in the 2006 trial, some surviving nematodes were observed in plots with both high (manure plus high density polyethylene film) and intermediate (pre-irrigation) 1,3-D cumulative emissions which suggested that emission loses are not solely responsible for some pest control failures. Weed control tended to be better with plastic film treatments and worse with pre-fumigation soil moisture manipulations but was affected less than expected by intermittent water seals. Although pest control clearly was affected by surface seal techniques, especially in shallow soil layers, some differences in nematode and weed control could not be explained solely by surface seals. These results underline the complex interactions among soil moisture and other environmental factors, application techniques, and emission reducing surface seal treatments. As new techniques and technologies become available to reduce fumigant emissions, we recommend that research include pest control efficacy evaluations before any emerging techniques are required by regulators or implemented by growers.

Weight change, body composition, and renin-angiotensin aldosterone system activity in midlife adults were compared between diet groups. Eighteen subjects enrolled in a 5-month study of 8-week controlled food intake followed by 12-weeks ad libitum intake. Subjects were randomized to 1 of 3 treatment groups: control diet (CD) (55% carbohydrate/15% protein/30% fat), mixed protein (40% carbohydrate/30% protein/30% fat), or whey protein (WP) (40% carbohydrate/15% mixed protein/15% whey protein/30% fat). Measurements included weight, metabolic measures, body composition by dual-energy x-ray absorptiometry, and resting energy expenditure. No statistically significant differences in total weight loss or total fat loss were observed between treatments; however, a trend toward greater total weight loss (P = .08) and total fat loss (P = .09) was observed in the WP group compared with the CD group. Fat loss in the leg and gynoid regions was greater (P .05) in the WP group than the CD group. No renin-angiotensin aldosterone system-mediated response was observed, but a decrease in systolic blood pressure was significantly greater (P .05) in the WP group compared with the CD group. In summary, increased whey protein intake did not result in statistically significant differences in weight loss or in total fat loss, but significant differences in regional fat loss and in decreased blood pressure were observed in the WP group.

Despite the serious impact of M. graminicola on wheat production worldwide, knowledge about its molecular biology is limited. The velvet gene, veA, is one of the key regulators of diverse cellular processes, including development and secondary metabolism in many fungi. However, the species analyzed to date are not related to the Dothideomycetes, the largest class of plant-pathogenic fungi, and the function of veA in this group is not known. To test the hypothesis that the velvet gene has similar functions in the Dothideomycetes, a veA-homologous gene, MVE1, was identified and gene deletion mutations ( Delta mve1) were generated in M. graminicola. All of the MVE1 mutants exhibited consistent pleiotropic phenotypes, indicating the involvement of MVE1 in multiple signaling pathways. Delta mve1 strains displayed albino phenotypes with significant reductions in melanin biosynthesis and less production of aerial mycelia on agar plates. In liquid culture, Delta mve1 strains showed abnormal hyphal swelling, which was suppressed completely by osmotic stress or lower temperature. In addition, MVE1 gene deletion led to hypersensitivity to shaking, reduced hydrophobicity, and blindness to light-dependent stimulation of aerial mycelium production. However, pathogenicity was not altered in Delta mve1 strains. Therefore, the light-signaling pathway associated with MVE1 does not appear to be important for Septoria tritici blotch disease. Our data suggest that the MVE1 gene plays crucial roles in multiple key signaling pathways and is associated with light signaling in M. graminicola.

As a first step, the quality of the bed sediments in water reservoirs must be determined before dredging operations. In this study, sediment samples from 34 stations of three selected water reservoirs (Zemplinska Sirava, Velke Kozmalovce, and Ruzin) were collected to investigate concentrations, distributions, and hazards of polychlorinated biphenyls (PCBs) and polycyclic aromatic hydrocarbons (PAHs) and to predict their possible sources. Total PCB concentrations were in the range of 20.4 to 2,325ng/g. The maximum concentrations of PCBs were found in sediments from Zemplinska Sirava, which is in the vicinity of a former manufacturer of PCBs. The composition of PCBs was characterized by tri- and hexa-CB congeners, indicating the influence of contamination from the use of specific Delor mixtures, formerly produced and massively used on the territory of Slovakia. The data showed that the highest total PAH concentrations were associated with the sediments from the Velke Kozmalovce, ranging from 7,910 to 29,538ng/g. On the other hand, the lowest total PAH concentrations (84-631ng/g of dry weight) were found in the sediments of Zemplinska Sirava, an important recreational area in eastern Slovakia. The distribution of individual PAHs was similar among the three water reservoirs, and this, together with principal component analysis and diagnostic PAH ratios, suggests mainly pyrolytic contamination of the sediments. However, petrogenic inputs appear to be important in the Zemplinska Sirava sediments.

This study evaluated the aroma volatiles of 20 tangerine hybrids of the University of Florida breeding program. Volatiles were sampled from hand-squeezed juice by headspace solid-phase microextraction (SPME), and analyzed by gas chromatography-mass spectrometry. Principal component analysis (PCA) and cluster analysis (CA) were used to find similarities among samples due to volatile composition with effect of genetic background. RESULTS: In total, 203 volatiles were detected in all samples. Volatiles in lower amounts were widely distributed among samples and were classified mainly as terpene hydrocarbons and oxygenated compounds, such as aldehydes, esters, alcohols and ketones. PCA, based on relative peak areas (content) clearly separated the samples higher in volatile content, mainly those with sweet orange genetic contributions in their background. CA, based on volatile presence/absence, grouped samples into five clusters, each showing distinctive volatile profiles. CONCLUSION: The genetic background of tangerine hybrids affected volatile composition and content of samples. In general, tangerines were characterized by fewer volatiles (in both quality and quantity) and more aldehydes, and hybrids with sweet orange in their background had more sesquiterpenes and esters, which would likely affect their aroma.

In a previous study, we demonstrated enhanced fungicide resistance in B. bassiana through artificial selection. However, it is not clear if the enhanced resistance was because of improved germination, vegetative growth, or both. Additionally, the enhanced fungicide resistance has only been demonstrated in B. bassiana, and therefore it is of interest to investigate the potential to enhance resistance in other fungi. Thus, the objectives in this study were to determine the potential to enhance fungicide resistance in M. brunneum through artificial selection, and investigate if selection is based on germination, vegetative growth, or both in B. bassiana and M. brunneum. Selection for resistance to fenbuconazole, and triphenyltin hydroxide was assessed through inhibition evaluations on solid media, and germination and mycelial growth in liquid media. Increased resistance after selection was observed for all fungicide-fungus combinations on solid and or liquid media. Selection resulted in increased resistance to fenbuconazole in both fungi in solid and liquid media; in liquid culture fungicide resistance in B. bassiana was manifested by increased germination and mycelial growth, whereas in M. brunneum fungicide resistance concerned only mycelial growth. Selection for resistance to triphenyltin hydroxide varied in the different media. For B. bassiana, triphenyltin hydroxide resistance was enhanced on solid media but not in liquid, whereas enhanced resistance of M. brunneum was detected in both media. Fungicide sensitivity and selection potential differs based on the medium and fungal species. Selection for fungicide resistance, had negative effects on other beneficial traits when fungicide pressure was removed, for example, some selected populations showed decreased germination or growth, relative to their nonselected control populations. Additionally, reduced virulence to the greater wax moth, Galleria mellonella (L.), was observed in all fungal populations that were exposed to fungicide resistance regimes. We conclude that it is possible to use genetic selection to enhance fungicide resistance in B. bassiana and M. brunneum, but before use the resulting populations should be screened for inadvertent negative impacts on beneficial traits.

Comparing salivary constituents among aphid species could help identify which salivary products are universally important for general aphid feeding processes, which products are involved with specific host associations, or which products elicit visible injury to hosts. We compared the salivary proteins from five aphid species, namely, Diuraphis noxia (Kurdjumov), D. tritici (Gillette), D. mexicana (Baker), Schizaphis graminum (Rondani), and Acyrthosiphon pisum (Harris). A 132-kDa protein band was detected from the saliva of all five species using sodium dodecyl sulfate Polyacrylamide gel electrophoresis. Alkaline phosphatase activity was detected from the saliva of all five species and may have a universal role in the feeding process of aphids. The Diuraphis species cause similar visible injury to grass hosts, and nine electrophoretic bands were unique to the saliva of these three species. S. graminum shares mutual hosts with the Diuraphis species, but visible injury to hosts caused by S. graminum feeding differs from that of Diuraphis feeding. Only two mutual electrophoretic bands were visualized in the saliva of Diuraphis and S. graminum. Ten unique products were detected from the saliva of A. pisum, which feeds on dicotyledonous hosts. Our comparisons of aphid salivary proteins revealed similarities among species which cause similar injury on mutual hosts, fewer similarities among species that cause different injury on mutual hosts, and little similarity among species which feed on unrelated hosts.

To overcome these difficulties two bioassays were developed: a two-choice test with airflow and a diffusion-based test to evaluate responses to chemical stimuli. The two-choice assay is excellent for rapidly comparing two stimuli or examining the response to one stimulus against a control. The diffusion assay determines differences in orientation behavior to multiple simultaneous stimuli and can examine other behaviors during exposure. Preparation of individuals for bioassay is also important, because disturbance increases the activity level of individual beetles beyond the duration of the disturbance. The age and the sex of beetles affect responsiveness to chemical cues. These bioassays and a better understanding of T. castaneum's activity have revealed approaches for evaluating its responsiveness to behavior-modifying chemicals.

Studies of mountain plovers in shortgrass steppe during the 1970s and 1990s were focused in Weld County, Colorado, which was considered a key breeding area for the species. These studies, however, did not include habitats influenced by black-tailed prairie dogs (Cynomys ludovicianus) or prescribed fire. The role of these 2 rangeland disturbance processes has increased substantially over the past 15 years. During 2008aa2009, I used radial distance point count surveys to estimate mountain plover densities early in the nesting season in 4 habitats on public lands in Weld County, Colorado. All 4 habitats were grazed by cattle during the growing season at moderate stocking rates but had different additional disturbances consisting of 1) dormant-season prescribed burns, 2) active black-tailed prairie dog colonies, 3) black-tailed prairie dog colonies affected by epizootic plague in the past 1aa2 years, and 4) rangeland with no recent history of fire or prairie dogs. Mountain plover densities were similar on active black-tailed prairie dog colonies ( = 6.8 birds/km2, 95% CI = 4.3aa10.6) and prescribed burns ( = 5.6 birds/km2, 95% CI = 3.5aa9.1). In contrast, no plovers were detected at randomly selected rangeland sites grazed by cattle but lacking recent disturbance by prairie dogs or fire, even though survey effort was highest for this rangeland habitat. Mountain plover densities were intermediate (2.0 birds/km2, 95% CI = 0.8aa5.0) on sites where black-tailed prairie dogs had recently been extirpated by plague. These findings suggest that prescribed burns and active black-tailed prairie dog colonies may enhance breeding habitat for mountain plovers in shortgrass steppe and illustrate the potential for suppressed or altered disturbance processes to influence habitat availability for declining wildlife species.

Red-winged blackbird (Agelaius phoeniceus) damage was higher for untreated than AV-1011ARGARG treated rice seedlings at assessment period 3, 15 days postplanting (F1,141 = 15.81, P < 0.001), and at assessment period 4, 19 days postplanting F1,136 = 11.54, P = 0.001). Blackbird damage to AV-1011-treated seedling for assessment periods 3 and 4 was 8% and 7%, respectively, while blackbird damage to untreated seedlings during the same assessment periods was 52% and 44%. More blackbirds used untreated plots than AV-1011-treated plots during assessment periods 2aa4 (F1,17.8 = 20.02, P < 0.001). Overall concentrations of AQ on seeds averaged 5,993 AmAmg/g or 0.59% during the test period. Concentrations of AQ in mature rice seed and plant collected at harvest averaged 1.22 AmAmg/g and 0.10 AmAmg/g, respectively. AV-1011 offers promise for reducing bird depredations to newly planted rice, but additional testing should be conducted to evaluate this repellent in a large-scale field setting.

K. Koch], Current control recommendations are based on chemical insecticide applications. Microbial control agents such as the entomopathogenic nematode, Steinernema carpocapsae (Weiser) and the fungus Beauveria bassiana (Balsamo) Vuillemin occur naturally in southeastern U.S. pecan orchards and have shown promise as alternative control agents for C. caryae. Conceivably, the chemical and microbial agents occur simultaneously within pecan orchards or might be applied concurrently. The objective of this study was to determine the interactions between two chemical insecticides that are used in commercial C. caryae control (i.e., carbaryl and cypermethrin applied below field rates) and the microbial agents B. bassiana and S. carpocapsae. In laboratory experiments, pecan weevil larval or adult mortality was assessed after application of microbial or chemical treatments applied singly or in combination (microbial + chemical agent). The nature of interactions (antagonism, additivity, or synergy) in terms of weevil mortality was evaluated over 9 d (larvae) or 5 d (adults). Results for B. bassiana indicated synergistic activity with carbaryl and antagonism with cypermethrin in C. caryae larvae and adults. For S. carpocapsae, synergy was detected with both chemicals in C. caryae larvae, but only additive effects were detected in adult weevils. Our results indicate that the chemical-microbial combinations tested are compatible with the exception of B. bassiana and cypermethrin. In addition, combinations that exhibited synergistic interactions may provide enhanced C. caryae control in commercial field applications; thus, their potential merits further exploration.

Sequence alignments show that the 16S rRNA gene of strain CA5 super(T) differed from that of P. argentinensis, P. flavescens, and P. straminea by 1.3, 1.5, and 1.7%, respectively. The G+C content was 62.8mol%, similar to the 62.7-63mol% reported for P. flavescens but slightly higher than the 62.5-62.6mol% of P. straminea and significantly higher than the 57.5-58.0mol% of P. argentinensis. The major cellular fatty acids present in the CA5 super(T) strain were C sub(18:1) omega 7c (41.1%), C sub(16:1) omega 6c and C sub(16:1) omega 7c (25.7%), C sub(16:0) (12.0%), C sub(12:0) (8.0%), C sub(12:0) 3-OH (4.4%), and C sub(10:0) 3-OH (2.9%). The cellular fatty acid profile, GC content, phenotypic properties, and biochemical characteristics were consistent with its placement within the genus Pseudomonas. The name P. seleniipraecipitatus is proposed for these bacteria.

The irrigation treatments included: (1) irrigating twice between cuttings with nonsaline water, (2) irrigating twice with moderately saline water between cuttings, and(3) once between cuttings with moderately saline water. Yield data demonstrated an approximately 30% reduction in total yield over 3 years as a result of using the saline water for irrigation compared to irrigating with the nonsaline water. The overall alfalfa quality improved when irrigated with saline water compared to the non-saline water. However, both boron and chloride progressively accumulated in alfalfa plant tissue during each growing season when irrigated with saline water. The plant tissue boron and chloride values returned to previously low levels by the start of the next growing season due to the influence of winter rainfall and irrigating with low-salinity water at the break of dormancy. There was measurable accumulation of salt in the soil profile and in the shallow groundwater as a result of using saline drainage water for irrigation. A gradual decrease in depth to the shallow groundwater was observed as result of the lack of drainage capability. Electromagnetic induction proved adequate for characterizing root zone salinity with time. Published in 2010 John Wiley & Sons, Ltd. Une etude de trois ans a examine l'utilisation d'eaux de drainage salines (EC < 6 dS mW 22; 1) pour l'irrigation de luzerne tolerante au sel en presence d'eaux souterraines salines peu profondes. Les traitements d'irrigation incluaient: (1) deux irrigations entre les coupes avec de l'eau non-saline, 2) deux irrigations avec de l'eau moderement saline entre les coupes, et (3) une irrigation entre les coupes avec de l'eau moderement saline. Les donnees de rendement ont demontre une reduction approximative de 30% de la production totale sur 3 ans en raison de l'utilisation d'eau saline pour l'irrigation comparee a de l'eau non-saline. La qualite globale de la luzerne s'est amelioree lorsqu'irriguee avec de l'eau saline comparee a l'eau non-saline. Cependant, le bore et le chlorure se sont progressivement accumules dans le tissu vegetal de la luzerne pendant chaque periode de vegetation lorsqu'irriguee avec de l'eau saline. Les teneurs en bore et en chlorure du tissu vegetal sont revenues aux niveaux precedemment bas au debut de la periode de vegetation suivante en raison de l'influence des precipitations d'hiver et de l'irrigation avec de l'eau a faible salinite au moment de la dormance. Il y avait une accumulation mesurable de sel dans le profil du sol et dans les eaux souterraines peu profondes en raison d'utilisation d'eaux salines de drainage pour l'irrigation. Une diminution progressive du niveau des eaux souterraines peu profondes a ete observee en raison du manque de capacites de drainage. L'induction electromagnetique a prouve etre adequate pour caracteriser la salinite de la zone racinaire en fonction du temps. Published in 2010 John Wiley & Sons, Ltd.

To measure parasitism by O. agrili, laboratory-reared "sentinel EAB eggs" were deployed under bark flaps on trunks of selected ash trees in both parasitoid-release and non-release control plots. In addition, naturally occurring EAB eggs were collected in both parasitoid-release and control plots to measure parasitism. While no parasitism was detected with either sentinel or naturally occurring EAB eggs in control plots in either 2008 or 2009, a low level of parasitism by O. agrili was detected in the parasitoid-release plots in both artificially deployed sentinel eggs ([less-than-or-equals, slant]1%) and field-collected, naturally occurring eggs (1.1-4.2%) in both years. In addition to losses due to parasitism by O. agrili, a large proportion (37-52%) of the field-deployed sentinel eggs disappeared, possibly due to predators such as ants, in both parasitoid-release and control plots. While no statistical differences in parasitism by O. agrili were detected between parasitoid release and control plots, other sources of egg mortality such as disappearance due to predation on eggs, varied significantly across study sites in both 2008 and 2009. The relevance of these findings to future release and evaluation strategies for O. agrili for biological control of the invasive emerald ash borer in the US is discussed.

Drying conidia of Trichoderma spp. in large scale production remains the major constraint because conidia lose viability during the drying process at elevated temperatures. Moreover, caking must be avoided during drying because heat generated by milling conidial chunks will kill conidia. It is ideal to dry conidia into a flow-able powder for further formulation development. A method was developed for microencapsulation of Trichoderma conidia with sugar through spray drying. Microencapsulation with sugars, such as sucrose, molasses or glycerol, significantly (P 0.05) increased the survival percentages of conidia after drying. Microencapsulation of conidia with 2% sucrose solution resulted in the highest survival percentage when compared with other sucrose concentrations and had about 7.5 x 10 super(10) cfu in each gram of dried conidia, and 3.4 mg of sucrose added to each gram of dried conidia. The optimal inlet/outlet temperature setting was 60/31 degree C for spray drying and microencapsulation. The particle size of microencapsulated conidia balls ranged from 10 to 25 mu m. The spray dried biomass of T. harzianum was a flow-able powder with over 99% conidia, which could be used in a variety of formulation developments from seed coatings to sprayable formulations.

Most MFCs use oxygen as the oxidant in the cathode chamber. This study examined the formation in culture of an unidentified bacterial oxidant and investigated the performance of this oxidant in a two-chambered MFC with a proton exchange membrane and an uncoated carbon cathode. DNA, FAME profile and characterization studies identified the microorganism that produced the oxidant as Burkholderia cenocepacia. The oxidant was produced by log phase cells, oxidized the dye 2,2'-azino-bis(3-ethylbenzthiazoline-6-sulphonic acid) (ABTS), had a mass below 1kD, was heat stable (121 degree C) and was soluble in ethanol. In a MFC with a 1000 Omega load and ABTS as a mediator, the oxidizer increased cell voltage 11 times higher than atmospheric oxygen and 2.9 times higher than that observed with ferricyanide in the cathode chamber.

We tested the hypothesis that differences in macro-aggregation are due to changes in soil structure related to management treatment-induced microbiological changes. In an experiment, microbiological factors consisting of aggregate stability, glomalin, russuloid basidiomycete fungi, uronic acids, total organic C (TOC), and total N (TN) were quantified in macroaggregate-size classes ranging from 4.75 to 0.25mm, collected at 0-5cm depth for the following treatments: (1) 12th year of fallow phase after 11years of conventional- and no-tilled spring wheat-fallow (CTF and NTF), (2) 12th year of lentil phase after 11years of conventional- and no-tilled spring wheat-lentil (CTL and NTL), (3) 12years no-tilled continuous spring wheat (NTCW), and (4) 16years uncultivated pasture (P) used as a baseline treatment. Immunoreactive easily extractable glomalin concentration was five to six times greater under P, NTCW, or NTL in the 2.00-1.00- and 1.00-0.50-mm macroaggregate-size classes than the other treatments and these results corroborated well with the results from aggregate stability assays. Russuloid basidiomycetes were highest in all NTCW macroaggregate-size classes, suggesting that annual input of lignin-containing wheat residues may influence the growth and survival of these fungi. Uronic acid amounts were highest in P but did not differ among the other treatments. In all macroaggregate-size classes, TOC content was greater in NTCW compared to CTF, and TN was about three times higher in NTL than NTF or CTF. In conclusion, 12years of NTCW management in semi-arid soil has resulted in higher macroaggregate stability, glomalin concentration, russuloid basidiomycete populations, and TOC in macroaggregates compared to alternate-year fallow. Lentil can be used to replace fallow in dryland wheat rotation under no-till to enhance TN content and improve soil macro-aggregation.

The accompanying increases in woody vegetation at many alpine treeline (hereafter treeline) locations provided an opportunity to examine how biotic and abiotic local site conditions interact to control tree establishment patterns during warming. We devised a landscape ecological approach to investigate these relationships at an undisturbed treeline in the Alaska Range. We identified treeline changes between 1953 (aerial photography) and 2005 (satellite imagery) in a geographic information system (GIS) and linked them with corresponding local site conditions derived from digital terrain data, ancillary climate data, and distance to 1953 trees. Logistic regressions enabled us to rank the importance of local site conditions in controlling tree establishment. We discovered a spatial transition in the importance of tree establishment controls. The biotic variable (proximity to 1953 trees) was the most important tree establishment predictor below the upper tree limit, providing evidence of response lags with the abiotic setting and suggesting that tree establishment is rarely in equilibrium with the physical environment or responding directly to warming. Elevation and winter sun exposure were important predictors of tree establishment at the upper tree limit, but proximity to trees persisted as an important tertiary predictor, indicating that tree establishment may achieve equilibrium with the physical environment. However, even here, influences from the biotic variable may obscure unequivocal correlations with the abiotic setting (including temperature). Future treeline expansion will likely be patchy and challenging to predict without considering the spatial variability of influences from biotic and abiotic local site conditions.

S.J. Darbyshire] is naturally infected with a fungal endophyte, Neotyphodium coenophialum, which produces toxic ergot alkaloids that negatively affect herbivores and may alter soil microbial communities. A 60-week mesocosm study with a factorial arrangement of soil type (clay loam and loamy sand) and endophyte infection (with and without) was conducted to determine changes in soil microbial community function (substrate utilization using Biolog), structure (phospholipid fatty acid profile), and glomalin concentration. Microbial utilization of carbohydrate, carboxylic acid, and miscellaneous substrate groups was lower in soil planted to endophyte-infected tall fescue than in soil planted to endophyte-free tall fescue. Gram-positive bacteria, arbuscular mycorrhizae, and glomalin in small (0.25-1.0mm) and large (>1mm) water-stable macro-aggregates were also negatively affected by endophyte infection. Although microbial changes due to endophyte infection were not ubiquitous and overwhelming, they were consistent with previous observations of reduced decomposition of endophyte-infected tall fescue plant litter, which may lead to greater soil C sequestration.

A common approach to identify and quantify landscape structure is with a landscape scale model known as a contagion index. A contagion index quantifies two distinct components of landscape diversity: composition and configuration. Some landscape ecologists promote the use of relative contagion indices. It is demonstrated that relativized contagion indices are mathematically untenable. Two new theoretical contagion indices, Gamma sub(1) and Gamma sub(2), are derived using a mean value approach (i.e., statistical expected value) instead of entropy. Behavior of Gamma sub(1) and Gamma sub(2) was investigated with simulated random, uniform, and aggregated landscapes. They are shown to be well-behaved and sensitive to composition and configuration. Distributional properties of Gamma sub(1) and Gamma sub(2) are derived. They are shown to be asymptotically unbiased, consistent, and asymptotically normally distributed. Variance formulas for Gamma sub(2) and Gamma sub(2) are developed using the delta method. The new index models are used to examine landscape diversity on three physiographic provinces in Alabama by analyzing the pattern and changes in forest cover types over the recent past. In comparing Gamma sub(1) and Gamma sub(2), use of Gamma sub(1) in analysis of variance gave a more conservative test of contagion.

Numerous small, cysteine-rich proteins have been shown to play a critical role in fungal-plant-bacterial associations. The discovery of six KP4-like genes in F. verticillioides precipitated efforts to understand their function and evolutionary origin. Analysis of publicly available genomic sequence identified 31 additional KP4-like genes from a range of Ascomycota, a Basidiomycota, and the moss Physcomitrella patens. Sequence comparison and phylogenetic analysis indicate that the viral KP4 and the moss and fungal KP4-like genes evolved from a common ancestor providing evidence for lateral gene transfer between kingdoms. Six genes of the 37 total genes are predicted to encode a protein with two, non-identical KP4-like domains in tandem separated by 29-56 amino acids. The results suggest that two independent events led to the dual-domain KP4 genes present in different lineages of the Ascomycota. Understanding the nature and function of KP4-like proteins in mycotoxin-producing species like Fusarium may help to limit plant diseases and increase food safety and food production.

It was observed that the vertically translocated bacteria (in log10cfu/g) was directly proportional to the logarithm of the tenderization depth, with an average translocation coefficient of 3.14+/-0.66log10cfu/g per log10mm of depth. For lateral cross-contamination, the bacterial counts recovered from the top layers of the first four pieces of meat decreased by approximately 0.5log10cfu/g after each tenderization. There was no decrease in the bacterial counts recovered from the top layers after the 4th tenderization. More tenderization studies were needed to quantitatively analyze the trend of lateral cross-contamination. However, it is evident that both vertical translocation and lateral cross-contamination can occur during mechanical tenderization of meat. Foodborne illnesses caused by consumption of undercooked non-intact beef meats contaminated with Escherichia coli O157:H7 are an emerging public food safety concern as evidenced by a major outbreak recently. This study investigated both vertical translocation and lateral cross-contamination of E. coli O157:H7 during mechanical tenderization of beef.

The transcript levels of GhCesA4 are significantly up-regulated as secondary cell wall cellulose is produced in developing cotton fibers. To understand the molecular mechanisms involved in transcriptional regulation of GhCesA4, beta -glucuronidase (GUS) activity regulated by a GhCesA4 promoter (-2574/+56) or progressively deleted promoters were determined in both cotton tissues and transgenic Arabidopsis. The spatial regulation of GhCesA4 expression was similar between cotton tissues and transgenic Arabidopsis. GUS activity regulated by the GhCesA4 promoter (-2574/+56) was found in trichomes and root vascular tissues in both cotton and transgenic Arabidopsis. The -2574/-1824 region was responsible for up-regulation of GhCesA4 expression in trichomes and root vascular tissues in transgenic Arabidopsis. The -1824/-1355 region negatively regulated GhCesA4 expression in most Arabidopsis vascular tissues. For vascular expression in stems and leaves, the -898/-693 region was required. The -693/-320 region of the GhCesA4 promoter was necessary for basal expression of GhCesA4 in cotton roots as well as Arabidopsis roots. Exogenous phytohormonal treatments on transgenic Arabidopsis revealed that phytohormones may be involved in the differential regulation of GhCesA4 during cotton fiber development.

Minimizing depredations and increasing tolerance by livestock producers will be critical for conservation efforts. To investigate factors influencing calf mortality and producer detection rates (i.e., number of livestock killed by predators, found by producers, and correctly classified as to cause of death), we monitored radio-tagged domestic calves at two sites in the Mexican wolf recovery area (East Eagle [EE] and Adobe Ranch [AR]). Study areas differed in grazing practices, density of predators (mountain lions, black bears, coyotes, and Mexican wolves), and amount of effort spent monitoring cattle. We radiotagged 618 calves over 3.5years, and 312 calves over 2years on the EE and AR, respectively. The overall proportion of radioed calves that died was higher on the EE (6.5%) than on the AR (1.9%). Predators (especially mountain lions) accounted for 85% of mortality on the EE and 0% on the AR. Calves selected by predators were on average 25days younger than the surviving cohort. Our results indicate that year-round calving, especially in areas with high predator densities, are subject to higher losses primarily because calves are exposed to mortality agents for longer periods of time rather than having higher natural rates of mortality. We found a significant difference in producer detection rates between study sites, likely due to differences in the intensity of monitoring cattle between sites. On the EE, the producer detected 77.5% of mortalities and on the AR, the producer detected 33% of mortalities. Our results support changing husbandry practices to limit calving to a seasonal endeavor and that performance payment may be a better compensation strategy than ex post compensation schemes.

Although the bacteria of cattle feces have been well characterized using culture-based and culture-independent methods, techniques have been lacking to correlate total community composition with community function. We used high throughput sequencing of total DNA extracted from fecal material to characterize general community composition and examine the repertoire of microbial genes present in beef cattle feces, including genes associated with antibiotic resistance and bacterial virulence. Results suggest that traditional 16S sequencing using "universal" primers to generate full-length sequence may under represent Acitinobacteria and Proteobacteria. Over eight percent (8.4%) of the sequences from our beef cattle fecal pool sample could be categorized as virulence genes, including a suite of genes associated with resistance to antibiotic and toxic compounds (RATC). This is a higher proportion of virulence genes found in Sargasso sea, chicken cecum, and cow rumen samples, but comparable to the proportion found in Antarctic marine derived lake, human fecal, and farm soil samples. The quantitative nature of metagenomic data, combined with the large number of RATC classes represented in samples from widely different habitats indicates that metagenomic data can be used to track relative amounts of antibiotic resistance genes in individual animals over time. Consequently, these data can be used to generate sample-specific and temporal antibiotic resistance gene profiles to facilitate an understanding of the ecology of the microbial communities in each habitat as well as the epidemiology of antibiotic resistant gene transport between and among habitats.

Immune defence is particularly relevant to survival in migratory bands, but little is known about the role of nutrition in insect immunity, particularly in nature. We hypothesized that immune defences are compromised in Mormon cricket bands because of nutrient limitations. Members of a migratory band in Nevada, U.S.A., preferred carbohydrate diets over proteins. After feeding on the carbohydrate diet, migratory velocity was less and the ability to encapsulate foreign particles and lyse bacteria was greater than for Mormon crickets consuming protein. Less locomotory demand for lipids may result in greater antibacterial activity. Total phenoloxidase (PO) activity also increased following feeding on carbohydrates, whereas spontaneously active PO was not different between the two diets. These results were very different from those of a band in Utah, U.S.A., that preferred the protein diet and that had enhanced spontaneous PO activity after protein supplementation. Haemolymphaaof Mormon crickets from the Nevada band was sampled 18h after the diet treatments, whereas that from the Utah band was drawn 4h after treatment. Either the difference in immune measures was due to the difference in sampling time, or spontaneous PO activity was protein-limited whereas encapsulation and antibacterial activity required carbohydrates. Currencies for the generalized immunity of insects may differ, and constraints on immunity in a given environment depend on which macronutrients are in short supply.

The production of mannitol by fermentation has become attractive because of the problems associated with its production chemically. A number of homo- and heterofermentative lactic acid bacteria (LAB), yeasts, and filamentous fungi are known to produce mannitol. In particular, several heterofermentative LAB are excellent producers of mannitol from fructose. These bacteria convert fructose to mannitol with 100% yields from a mixture of glucose and fructose (1:2). Glucose is converted to lactic acid and acetic acid, and fructose is converted to mannitol. The enzyme responsible for conversion of fructose to mannitol is NADPH- or NADH-dependent mannitol dehydrogenase (MDH). Fructose can also be converted to mannitol by using MDH in the presence of the cofactor NADPH or NADH. A two enzyme system can be used for cofactor regeneration with simultaneous conversion of two substrates into two products. Mannitol at 180gl super(-1) can be crystallized out from the fermentation broth by cooling crystallization. This paper reviews progress to date in the production of mannitol by fermentation and using enzyme technology, downstream processing, and applications of mannitol.

A conceptual framework first suggested by Chapin et al. ( ) was adapted to address the question of why CO2 effects on primary productivity vary so greatly among rangelands and among years for a given ecosystem. The 'interactive controls' framework is based on the premise that the influence of elevated CO2 on productivity is governed by a set of internal variables that interact dynamically with ecosystem processes. These interactive controls, which include regional climate, soil resource supply, major functional groups of organisms and disturbance regimes, both regulate CO2 effects on ecosystems and respond to CO2 effects. Changes in interactive controls resulting from CO2 enrichment may feed back to dampen or amplify ecosystem responses to CO2 . Most feedbacks from interactive controls will be negative and dampen CO2 effects on ecosystems. Negative feedbacks promote homeostasis in ecosystem processes and reduce the response of plant productivity to CO2 . Positive feedbacks on CO2 responses are fewer, but can sustain or even increase benefits of CO2 enrichment for productivity. Positive feedbacks on CO2 responses occur most frequently through changes in plant species and functional group composition. Understanding positive and negative feedbacks on CO2 responses could be one key to predicting consequences of CO2 enrichment for rangeland productivity and other processes.

Thirty-nine male elite martial artists were assessed on 12 affective states, concerns and dimensions of primary and secondary appraisal at five random times a day across 1 week before and 3 days after a competition. On the competition day, they were assessed 1h before and immediately after the contest. Competitive trait anxiety, neuroticism and extraversion were measured at the start of the study. The competition was the most significant and stressful event experienced in the examined period and had a pervasive influence on athletes' affective states. All examined appraisal and personality factors were somewhat associated with pre- and post-competition affective states. Competitive trait anxiety was a key moderator of the relationship between cognitive appraisal and affective states.

These factors need to be accounted for in planning of emotion regulation interventions.

Preliminary studies in 2008 found that the clear was more effective than a coloured trap for G. molesta in a sex pheromone-treated peach orchard (OFM-MD); and for both species in an untreated (non-MD) peach orchard. Similarly, the clear outperformed the orange trap when both were baited with terpinyl acetate (TA) plus (Z)-3-hexen-1-yl acetate lures. Studies were expanded during 2009 to include commercial orchards in WA, OR, CA, and PA. Trap comparisons with sex pheromone lures of G. molesta were more variable with clear outperforming coloured traps in three of six trials in non-MD orchards. The clear outperformed the coloured trap with sex pheromone lures for A. lineatella in all four non-MD orchards. Seasonal catches of G. molesta in sex pheromone-baited traps in OFM-MD orchards were less than or equal to 0.3 moths per trap in all but one study with no significant difference found between traps. Seasonal catches of A. lineatella in PTB-MD orchards were generally low with both traps and significantly higher in clear traps in only one study. Traps baited with TA outperformed sex pheromone lures for G. molesta in OFM-MD peach orchards; and clear outperformed coloured traps. Clear traps baited with TA plus (Z)-3-hexen-1-yl acetate caught significantly more G. molesta than similarly-baited red traps in an almond orchard and more than both trap types baited with TA alone. Catches of A. lineatella in the OFM/PTB-MD almond orchard were low with both lures in either trap.

It attains outbreak population levels sufficient to mass attack host pines across the landscape at scales ranging from a single forest stand to interstate epidemics. This county level analysis selected and examined the best climatic and landscape variables for predicting infestations at regional scales. The analysis showed that, for a given county, the most important factor in predicting outbreaks was that the county was classified as in outbreak status in the previous year. Other important factors included minimum winter temperature and the greatest difference between the average of daily minimums and a subsequent low temperature point, precipitation history either seasonally in the previous year or difference from average over the previous 2 years, the synchronizing effect of seasonal temperatures on beetle populations and the relative percentage of total forest area composed of host species. The statistical models showed that climatic variables are stronger indicators of outbreak likelihood than landscape structure and cover variables. Average climatic conditions were more likely to lead to outbreaks than extreme conditions, supporting the notion of coupling between a native insect and its native host. Still, some extreme events (i.e., periods of very low temperature or very high precipitation) did precede beetle infestation. This analysis suggested that there are predisposing and inciting factors at the large scale but the driving factors leading to individual infestations operate at smaller scales.

The objective was to evaluate the impact of low rates of N applied at planting on soybean N fixation and crop growth. A field experiment was established within corn soybean rotation using a split-plot design with four replications. Whole plots were no-tillage and conventional tillage and split plots were starter fertilizer. Nitrogen sources were ammonium nitrate or urea applied at four rates. The amount of plant N fixation increased with growth stage reaching a maximum fixation at the R5 growth stages. Plant ureide content decrease with increase N applied for all growth stages except R7. The increase in plant biomass contributed to an overall increase in yield indicating that in unfavorable environments application of N at planting can have a positive impact on soybean growth.

In comparison, sample preparation for sugar analysis of hydrolyzed biomass samples using liquid chromatography is a simple dilution procedure with water. A gradient HPLC method using a anion-exchange column and pulsed-amperometric detection modified to reduce analysis time from 75 to 40min was further improved. The new method no longer requires post-column addition to stablilize the baseline using a pulsed-amperometric detector with the mobile phase gradient. The method provides good resolution of arabinose, rhamnose, galactose, xylose, glucose, fructose, sucrose, cellobiose, and galacturonic acid in both standards and hydrolyzed citrus waste materials. By changing the waveform used with the PAD detector, the requirement for post-column addition was eliminated while maintaining a stable baseline.

Many urgent social and environmental issues require spatially-referenced information on land-use, a need potentially met by the National Land-Cover Data (NLCD). NLCD non-site-specific accuracy from 1992 and 2001 was assessed by comparing county proportions of cropland and agricultural grassland (pasture/hay) area to those recorded in the USDA Census of Agriculture (COA) for 1992 and 2002. Estimates of total agricultural area corresponded closely (r super(2) = 0.91 for 1992; 0.85 for 2001/2), but NLCD performed poorly at distinguishing between cropland and grassland (r super(2) = 0.64 and 0.80 for cropland in 1992 and 2001; 0.50 and 0.44 for grassland in those years). High forest cover reduced accuracy. Landscape complexity and patch size may impede classification accuracy. Accuracy varied greatly by state, even within a single mapping region. The NLCD is the best available source of spatial land-cover, but may not be suitable for applications requiring agricultural subclass data.

In the present study, composite interval mapping was used to identify the QTLs that condition resistance to the 6 out of the 12 common races (IB1, IB45, IB49, IB54, IC17, and ID1) of M. oryzae using a recombinant inbred line (RIL) population derived from a cross of the moderately susceptible japonica cultivar Lemont with the moderately resistant indica cultivar Jasmine 85. Disease reactions of 227 F sub(7) RILs were determined using a category scale of ratings from 0, representing the most resistant, to 5, representing the most susceptible. A total of nine QTLs responsive to different degrees of phenotypic variation ranging from 5.17 to 26.53% were mapped on chromosomes 3, 8, 9, 11, and 12: qBLAST3 at 1.9 centimorgans (cM) to simple sequence repeat (SSR) marker RM282 on chromosome 3 to IB45 accounting for 5.17%; qBLAST8.1 co-segregated with SSR marker RM1148 to IB49 accounting for 6.69%, qBLAST8.2 at 0.1 cM to SSR marker RM72 to IC17 on chromosome 8 accounting for 7.22%; qBLAST9.1 at 0.1 cM to SSR marker RM257 to IB54, qBLAST9.2 at 2.1 cM to SSR marker RM108, and qBLAST9.3 at 0.1 cM to SSR marker RM215 to IC17 on chromosome 9 accounting for 4.64, 7.62, and 4.49%; qBLAST11 at 2.2 cM to SSR marker RM244 to IB45 and IB54 on chromosome 11 accounting for 26.53 and 19.60%; qBLASTH.1 at 0.3 cM to SSR marker OSM89 to IB1 on chromosome 12 accounting for 5.44%; and qBLAST12.2 at 0.3 and 0.1 cM to SSR marker OSM89 to IB49 and ID1 on chromosome 12 accounting for 9.7 and 10.18% of phenotypic variation, respectively.

Determine the change in ex vivo WB cytokine production 6 months after restrictive bariatric surgery in the obese group. Subjects: Seventeen obese (BMI: 46.6 +/- 7.9 kg/m super(2)) and 19 non-obese (BMI: 22.5 +/- 3.0 kg/m super(2)), pre-menopausal women; frequency matched for hemoglobin, age and race. Measurements: At baseline control and ex vivo stimulated IL-6, IL-10, IL-22, IFN gamma , and TNF alpha from heparinized WB cultures, hemoglobin from finger-stick and transferrin receptor, hepcidin, CRP, IL-6, HOMA-IR from fasted serum samples and anthropometric parameters were assessed in the women. All parameters were reassessed 6-months following restrictive bariatric surgery in the obese women only. Results: Whole blood ex vivo LPS and ZY stimulated production of IL-6, TNF alpha , and IFN gamma was reduced, IL-22 increased, and IL-10 was unaffected in obese compared with the non-obese women. Furthermore, ex vivo stimulated production of IL-6 and TNF alpha normalized, but IFN gamma production remained unchanged with weight loss following restrictive bariatric surgery. In the obese women, serum transferrin receptor (a marker of iron status) and serum hepcidin were correlated with ex vivo stimulated IFN gamma production at baseline. Conclusion: Ex vivo LPS and ZY stimulated cytokine production from WB cultures was altered in pre-menopausal women with morbid obesity. Significant weight loss resulted in normalization of some but not all observed alterations.

In order to better characterize this partial resistance phenotype, we have compared host resistance responses mediated by RB with those mediated by the S. demissum-derwed R gene RB, which confers immunity to P. infestans carrying the corresponding avirulence gene avrR9. We found that both RB and R9 genes were capable of eliciting a hypersensitive cell death response (HR). However, in RB plants, the pathogen escaped HR lesions and continued to grow beyond the inoculation sites. We also found that callose deposition was negatively correlated with resistance levels in tested plants. Transcription patterns of pathogenesis-related (PR) genes PR-1 basic, PR-2 acidic, and PR-5 indicated that P. infestans inoculation induced transcription of these defense-related genes regardless of the host genotype; however, transcription was reduced in both the susceptible and partially resistant plants later in the infection process but remained elevated in the immune host. Most interestingly, transcription of the HR-associated gene Hin1 was suppressed in both Katahdin and HB-transgenic Katahdin but not in R9 4 days after inoculation. Together, this suggests that suppression of certain defense-related genes may allow P. infestans to spread beyond the site of infection in the partially resistant host despite elicitation of hypersensitive cell death.

Consequently, taxonomic relationships and biogeographical data are commonly believed to have the power to predict the distribution of disease resistance genes among plant species. In this study, we test claims of such predictivity in a group of widely distributed wild potato species. There was no clear association between resistance to soft rot and taxonomic relationships. However, we have found some associations between resistance to soft rot and environmental data such as annual precipitation and annual mean temperature. In addition, we have noted that high levels of resistance are mostly found in species with high levels of phenotypic plasticity. The three most resistant species were Solatium paucijugum, S. brevicaule, and S. comtnersonii.

The U.S. Department of Agriculture (USDA)-Agricultural Research Service, Sunflower Research Unit has released rust resistant breeding materials for several decades. However, constantly coevolving rust populations have formed new virulent races to which current hybrids have little resistance. The objectives of this study were to identify resistance to race 336, the predominant race in North America, and to race 777, the most virulent race currently known, and to validate molecular markers known to be linked to rust resistance genes in the sunflower gene pool. A total of 104 entries, including 66 released USDA inbred lines, 14 USDA interspecific germplasm lines, and 24 foreign germplasms, all developed specifically for rust resistance, were tested for their reaction to races 336 and 777. Only 13 of the 104 entries tested were resistant to both races, whereas another six were resistant only to race 336. The interspecific germplasm line, Rf ANN-1742, was resistant to both races and was identified as a new rust resistance source. A selection of 24 lines including 19 lines resistant to races 777 and/or 336 was screened with DNA markers linked to rust resistance genes R sub(1), R sub(2), R sub(4u), and R sub(5). The results indicated that the existing resistant lines are diverse in rust resistance genes. Durable genetic resistance through gene pyramiding will be effective for the control of rust.

The primary antimicrobial compounds in these products are acetic acid and NaCl, which can alter the intracellular physiology of E. coli O157:H7, leading to cell death. For combinations of acetic acid and NaCl at pH 3.2 (a pH value typical for non-heat-processed acidified vegetables), survival curves were described by using a Weibull model. The data revealed a protective effect of NaCl concentration on cell survival for selected acetic acid concentrations. The intracellular pH of an E. coli O157:H7 strain exposed to acetic acid concentrations of up to 40 mM and NaCl concentrations between 2 and 4% was determined. A reduction in the intracellular pH was observed for increasing acetic acid concentrations with an external pH of 3.2. Comparing intracellular pH with Weibull model predictions showed that decreases in intracellular pH were significantly correlated with the corresponding times required to achieve a 5-log reduction in the number of bacteria.

Heat-resistant salmonellae (three serovars of Enteritidis [two of phage type 8 and one PT 13] and one Oranienburg) were grown to stationary phase in Tryptic Soy Broth and concentrated 10-fold by centrifugation. Each inoculum was added to liquid egg yolk and mixed thoroughly, resulting in a final population of ca. 7logCFU/ml egg yolk. Inoculated yolk was injected into sterile glass capillary tubes, flame-sealed and heated in a water bath at 58, 60, 62, 64, and 66 degree C. Capillary tubes were ethanol sanitized, rinsed, and contents were extracted. Yolk was diluted, surface plated onto Tryptic Soy Agar+0.1% sodium pyruvate and 50 mu g/ml nalidixic acid and incubated at 37 degree C for 24h before colonies were enumerated. Decimal reduction values were calculated from survivor curves with a minimum inactivation of 6logCFU/ml at each temperature. Survival curves (except for 66 degree C) featured initial lag periods before first order linear inactivation. Estimated asymptotic D-values were 1.83min at 58 degree C, 0.69min at 60 degree C, 0.26min at 62 degree C, 0.096min at 64 degree C and 0.036min at 66 degree C. The estimate of the asymptotic z-value was ca. 4.7 degree C with standard error of 0.07 degree C. A linear relationship between the log10 of the lag times and temperature was observed. A general kinetic model of inactivation was developed. The results of the study provide information that can be used by processors to aid in producing safe pasteurized egg yolk products and for satisfying pasteurization performance standards and developing industry guidance.

At pH 3.0, the cells did not survive. Virulence assays using crystal violet binding, low-calcium response, Congo red-uptake, hydrophobicity by latex particle agglutination, and autoagglutination, as well as PCR assay to determine the presence of pYV indicated that the surviving cells were still virulent.

Numerous disease resistance screens of diverse Vitis germplasm have been conducted previously to identify powdery mildew resistance but ratings of named cultivars were inconsistent and identities of resistant individuals in wild species were not typically provided. In the current study, controlled inoculations of a single isolate were made onto detached leaves from 1,025 Vitis accessions. The results were compared with natural epidemics in two vineyards: the cold-hardy Vitis spp. repository in Geneva, NY, in 2007-08, and a replicated vineyard of 89 Vitis accessions in Fredonia, NY in 2006-08. Of the genotypes screened using both natural infection and single-isolate inoculation, 33% were resistant to a single isolate but susceptible to diverse isolates in either or both vineyards, possibly due to race-specific resistance. This was exemplified by selection of E. necator genotypes virulent to Vitis labrusca in the Fredonia, NY vineyard, which is surrounded by production of the interspecific labrusca hybrids Concord and Niagara. Otherwise, there was good correlation of ratings between the vineyard and single-isolate ratings (r = 0.55 to 0.56) and between Geneva and Fredonia vineyard ratings (r = 0.75). No accession rated in all three screens was immune from infection. Although individual accessions of V. aestivalis, V. palmata, Vitis X doaniana, and Ampelopsis brevipedunculata were resistant in Geneva and Fredonia, each well-represented species had notable intraspecific variation in resistance. For 129 interspecific hybrids in this and previous studies, ratings infrequently corresponded among previous studies (39%) and between the current and previous studies (17 to 46%). However, three cultivars (Cayuga White, Diana, and Mars) were consistently rated as resistant across four independent studies. The results underscore the importance of uniform testing in multiple environments and the need for strategies for the development of cultivars with durable resistance.

Fungal communities on maize dominated by the S strain of A. flavus have repeatedly been associated with acute aflatoxin poisonings in Kenya, where management tools to reduce aflatoxin levels in maize are needed urgently. A. flavus isolates (n = 290) originating from maize produced in Kenya and belonging to the L strain morphotype were tested for aflatoxin-producing potential. A total of 96 atoxigenic isolates was identified from four provinces sampled. The 96 atoxigenic isolates were placed into 53 vegetative compatibility groups (VCGs) through complementation of nitrate non-utilizing mutants. Isolates from each of 11 VCGs were obtained from more than one maize sample, isolates from 10 of the VCGs were detected in multiple districts, and isolates of four VCGs were found in multiple provinces. Atoxigenic isolates were tested for potential to reduce aflatoxin concentrations in viable maize kernels that were co-inoculated with highly toxigenic S strain isolates. The 12 most effective isolates reduced aflatoxin levels by >80%. Reductions in aflatoxin levels caused by the most effective Kenyan isolates were comparable with those achieved with a United States isolate (NRRL-21882) used commercially for aflatoxin management. This study identified atoxigenic isolates of A. flavus with potential value for biological control within highly toxic Aspergillus communities associated with maize production in Kenya. These atoxigenic isolates have potential value in mitigating aflatoxin outbreaks in Kenya, and should be evaluated under field conditions.

AN - 847433296; 20814671 AB - The toxicity of a nutrient-pesticide mixture in nonvegetated and vegetated sections of a constructed wetland (882 m² each) was assessed using Hyalella azteca 48-h aqueous whole-effluent toxicity bioassays. Both sections were amended with a mixture of sodium nitrate, triple superphosphate, diazinon, and permethrin simulating storm-event agricultural runoff. Aqueous samples were collected at inflow, middle, and outflow points within each section 5 h, 24 h, 72 h, 7 days, 14 days, and 21 days postamendment. Nutrients and pesticides were detected throughout both wetland sections with concentrations longitudinally decreasing more in vegetated than nonvegetated section within 24 h. Survival effluent dilution point estimates-NOECs, LOECs, and LCâ‚…â‚€s-indicated greatest differences in toxicity between nonvegetated and vegetated sections at 5 h. Associations of nutrient and pesticide concentrations with NOECs indicated that earlier toxicity (5-72 h) was from permethrin and diazinon, whereas later toxicity (7-21 days) was primarily from diazinon. Nutrient-pesticide mixture concentration-response assessment using toxic unit models indicated that H. azteca toxicity was due primarily to the pesticides diazinon and permethrin. Results show that the effects of vegetation versus no vegetation on nutrient-pesticide mixture toxicity are not evident after 5 h and a 21-day retention time is necessary to improve H. azteca survival to ≥90% in constructed wetlands of this size.

AN - 837455285; 20942652 AB - We have been using mutagenesis to determine how biocontrol bacteria such as Enterobacter cloacae 501R3 deal with complex nutritional environments found in association with plants. E. cloacae C10, a mutant of 501R3 with a transposon insertion in degS, was diminished in growth on synthetic cucumber root exudate (SRE), colonization of cucumber seed and roots, and control of damping-off of cucumber caused by Pythium ultimum. DegS, a periplasmic serine protease in the closely related bacterium Escherichia coli K12, is required for the RpoE-mediated stress response. C10 containing wild-type degS from 501R3 or from E. coli K12 on pBeloBAC11 was significantly increased in growth on SRE, colonization of cucumber roots, and control of P. ultimum relative to C10 containing pBeloBAC11 alone. C10 and 501R3 were similar in sensitivity to acidic conditions, plant-derived phenolic compounds, oxidative stress caused by hydrogen peroxide, dessication, and high osmoticum; stress conditions potentially associated with plants. This study demonstrates a role for degS in the spermosphere and rhizosphere during colonization and disease control by Enterobacter cloacae. This study implicates, for the first time, the involvement of DegS and, by extension, the RpoE-mediated stress response, in reducing stress on E. cloacae resulting from the complex nutritional environments in the spermosphere and rhizosphere.

Crosses between sexually compatible strains resulted in the formation of multiple nonostiolate ascocarps within stromata, which places the teleomorph in genus Petromyces. Ascocarp and ascospore morphology in Petromyces nomius were similar to that in P. flavus and P. parasiticus, and differences between teleomorphs were insufficient for species separation. Formation of mature ascocarps was infrequent, with only 24% of the 83 crosses producing viable ascospores. The majority of P. nomius strains contained a single mating-type gene (MAT1-1 or MAT1-2), but several strains contained both genes. MAT1-1/MAT1-2 strains were self-sterile and capable of mating with both MAT1-1 and MAT1-2 strains; hence P. nomius appears to be functionally heterothallic.

Research on honey bee health is surging, in part due to new tools and the arrival of colony-collapse disorder (CCD), an unsolved decline in bees from parts of the United States, Europe, and Asia. Although a clear understanding of what causes CCD has yet to emerge, these efforts have led to new microbial discoveries and avenues to improve our understanding of bees and the challenges they face. Here we review the known honey bee microbes and highlight areas of both active and lagging research. Detailed studies of honey bee-pathogen dynamics will help efforts to keep this important pollinator healthy and will give general insights into both beneficial and harmful microbes confronting insect colonies.

A variety of uses that have been considered are described here. In general, these rely on biomass constituent solubility enhanced by ethanol concentration and temperature so that lipids, proteins, and lignin may be dissolved and recovered. Additionally, ethanol may be applied to remove water from solids, such as wet starch, wet gluten, and distillers' wet grains. This technology has been described in the past as 'extractive' or 'displacement' drying and replaces conventional solids dehydration (a unit operation) with solvent drying plus solvent regeneration (a system of unit operations). Materials as diverse as wood, peat, coal, and starch have been dried experimentally in this way. General criteria using best-case assumptions for this replacement are developed here. Applied to ethanol, these suggest significant potential energy savings for a system that combines low-load solvent drying with distillation. Distillation energy for regenerating ethanol solvent to 90%v or less and producing water is equivalent to a 3 to 4 effect evaporation of water when compared on a separation-energy per unit-of-water-removed basis. Material properties of the dehydrated substance may be enhanced since the solvent drying is at a lower temperature and leaves the matrix without structural collapse. The parameters for capital cost comparison are delineated with important considerations and economies identified that result from the use of low-cost solvent and compatible technologies in the biorefinery setting.

Contrary to its interaction with Acanthamoeba spp., S. Typhimurium is not cytotoxic to Tetrahymena and is egested as viable cells in its fecal pellets. Through microarray gene expression profiling we investigated the factors in S. Typhimurium that are involved in its resistance to digestion by Tetrahymena. The transcriptome of S. Typhimurium in Tetrahymena phagosomes showed that 989 and 1282 genes were altered in expression compared with that in water and in LB culture medium, respectively. A great proportion of the upregulated genes have a role in anaerobic metabolism and the use of alternate electron acceptors. Many genes required for survival and replication within macrophages and human epithelial cells also had increased expression in Tetrahymena, including mgtC, one of the most highly induced genes in all three cells types. A Delta mgtC mutant of S. Typhimurium did not show decreased viability in Tetrahymena, but paradoxically, was egested at a higher cell density than the wild type. The expression of adiA and adiY, which are involved in arginine-dependent acid resistance, also was increased in the protozoan phagosome. A Delta adiAY mutant had lower viability after passage through Tetrahymena, and a higher proportion of S. Typhimurium wild-type cells within pellets remained viable after exposure to pH 3.4 as compared with uningested cells. Our results provide evidence that acid resistance has a role in the resistance of Salmonella to digestion by Tetrahymena and that passage through the protist confers physiological advantages relevant to its contamination cycle.

A range (6-26%) of DMA concentrations was used alone or in combination with ATP (30, 60 or 118 mM) or one of the following osmoprotectants: (1) sucrose (turkey, 8.0%; crane, 5.0%); (2) 5.0% sucrose and 5.0% trehalose; or (3) betaine hydrochloride (0.1, 0.2 or 0.4 mM). The viability of thawed sperm was assessed using the nigrosin-eosin stain and sperm motility was determined using the hanging-drop technique. For semen frozen only with DMA, post-thaw sperm motility was greatest (P < 0.05) for the 6.0%, 10.0% and 18% concentrations, regardless of species. Turkey sperm frozen with the sucrose/trehalose combination had greater (P < 0.05) post-thaw motility for all DMA treatments compared to DMA alone. The lowest concentration of the osmoprotectant betaine hydrochloride substantially improved turkey sperm viability post-thaw in all treatments compared to DMA alone (P < 0.05). The post-thaw motility of crane sperm was improved (P < 0.05) with a combination of 18.0%, 24.0% or 26.0% DMA and 30 mM ATP. Moreover, in the presence of osmoprotectants, crane sperm motility decreased as the osmoprotectant concentration increased. The lowest concentration of ATP also improved crane sperm viability post-thaw, especially for DMA concentrations 18% or greater. The combination of sucrose and trehalose improved (P < 0.05) crane sperm viability only with 6% and 10% DMA. These data affirm that there are avian-specific differences in sperm survival after cryopreservation and suggest that post-thaw survival can be enhanced by including species-based osmoprotectant/ATP combinations in a cryodiluent where DMA is the cryoprotectant.

However, these properties can only be exerted if the SLs can be introduced to the bacterial cells in an acceptable manner. Propionibacterium acnes is the common bacterial cause of acne. It is a Gram super(+) facultative anaerobe that is susceptible to the antimicrobial effects of SLs. In this study we demonstrated that different biopolymer matrices could be used to produce SL composite films that exert various antimicrobial efficiencies against P. acnes. Increasing SL concentrations in poly-3-hydroxybutyrate (PHB) and PHB-co-10%-3-hydroxyhexanoate (PHB/HHx) resulted in noticeably improved (PHB/HHx was best) antimicrobial activity based on the size of the zones of inhibition using an overlay plating technique on synthetic growth medium. However, increasing concentrations of SLs in PHB and PHB/HHx films also increased film opacity, which diminishes the appeal for use especially in visible (facial) areas. Pectin and alginate improved the transparent character of SL composite films while also acting as successful carriers of SLs to P. acnes. The lactone form of the SLs proved to exhibit the best antimicrobial action and in concert with either pectin or alginate biopolymers provided a comparatively transparent, successful means of utilizing SLs as a renewable, environmentally benign anti-acne solution.

That additional water is used most efficiently when a crop is present to transpire the water, and crop yields respond positively to increases in available soil water. The objective of this study was to evaluate yield, water use efficiency (WUE), precipitation use efficiency (PUE), and net returns of cropping systems where crop choice was based on established crop responses to water use while incorporating a grass/broadleaf rotation. Available soil water at planting was measured at several decision points each year and combined with three levels of expected growing season precipitation (70, 100, 130% of average) to provide input data for water use/yield production functions for seven grain crops and three forage crops. The predicted yields from those production functions were compared against established yield thresholds for each crop, and crops were retained for further consideration if the threshold yield was exceeded. Crop choice was then narrowed by following a rule which rotated summer crops (crops planted in the spring with most of their growth occurring during summer months) with winter crops (crops planted in the fall with most of their growth occurring during the next spring) and also rotating grasses with broadleaf crops. Yields, WUE, PUE, value-basis precipitation use efficiency ($PUE), gross receipts, and net returns from the four opportunity cropping (OC) selection schemes were compared with the same quantities from four set rotations [wheat-fallow (conventional till), (WF (CT)); wheat-fallow (no-till), (WF (NT)); wheat-corn (Zea mays L.)-fallow (no-till), (WCF); wheat-millet (Panicum miliaceum L.) (no-till), (WM)]. Water use efficiency was greater for three of the OC selection schemes than for any of the four set rotations. Precipitation was used more efficiently using two of the OC selection schemes than using any of the four set rotations. Of the four OC cropping decision methods, net returns were greatest for the method that assumed average growing season precipitation and allowed selection from all possible crop choices. The net returns from this system were not different from net returns from WF (CT) and WF (NT). Cropping frequency can be effectively increased in dryland cropping systems by use of crop selection rules based on water use/yield production functions, measured available soil water, and expected precipitation.

Crop residue coverage was derived from spectral data and used to classify sorghum and wheat fields into high and low crop residue categories. Denaturing gradient gel electrophoresis-polymerase chain reaction (DGGE-PCR) assays employing universal PCR primers that target prokaryotic and eukaryotic ribosomal genes were used to evaluate microbial community structure. An interaction between geographical location, crop type, and crop residue coverage was observed. A 50% similarity level was observed for overall bacterial community structure as determined using 16S data while a 59% similarity was observed for overall fungal community structure using 18S data. For the 16S composite dataset, high overall rates of correct classification (ORCC) were observed based on the user-defined groups of county by crop by residue coverage. A similar result was observed for fungal community structure using primer set FR1GC-FF390. Our data support the hypothesis that there are multiple provinces and multiple habitats that govern the assemblage of free-living taxa within the Moore-Ochiltree County agroecosystem. An ancient microbial assemblage based on historical features was identified and is still visible despite the presence of different crop types and cropping systems (Conventional vs. Conservation). For sorghum and wheat grown in Moore and Ochiltree Counties, a two-province state (Moore and Ochiltree Counties) was defined comprised of four habitats i.e. sorghum and wheat habitats influence by degree of residue coverage. Crop type and residue coverage can affect microbial assemblages within a geographical context.

AN - 835118350; 21092757 AB - Alzheimer disease elevates lipid peroxidation in the brain and data indicate that the resulting lipid-aldehydes are pathological effectors of lipid peroxidation. The disposition of 4-substituted nonenals derived from arachidonate (20:4, n-6) and linoleate (18:2, n-6) oxidation is modulated by their protein adduction targets, their metabolism, and the nature of the 4-substitutent. Trans-4-oxo-2-nonenal (4-ONE) has a higher toxicity in some systems than the more commonly studied trans-4-hydroxy-2-nonenal (HNE). In this work, we performed a structure-function analysis of 4-hydroxy/oxoalkenal upon mitochondrial endpoints. We tested the hypotheses that 4-ONE, owing to a highly reactive nature, is more toxic than HNE and that HNE toxicity is enantioselective. We chose to study freshly isolated brain mitochondria because of the role of mitochondrial dysfunction in neurodegenerative disorders. Whereas there was little effect related to HNE chirality, our data indicate that in the mitochondrial environment, the order of toxic potency under most conditions was 4-ONE>HNE. 4-ONE uncoupled mitochondrial respiration at a concentration of 5μM and inhibited aldehyde dehydrogenase 2 (ALDH2) activity with an IC(50) of approximately 0.5μM. The efficacy of altering mitochondrial endpoints was ALDH2 inhibition>respiration=mitochondrial swelling=ALDH5A inhibition>GSH depletion. Thiol-based alkenal scavengers, but not amine-based scavengers, were effective in blocking the effects of 4-ONE upon respiration. Quantum mechanical calculations provided insights into the basis for the elevated reactivity of 4-ONE>HNE. Our data demonstrate that 4-ONE is a potent effector of lipid peroxidation in the mitochondrial environment. Published by Elsevier Inc.

Our objective was to evaluate the success of using an active canopy sensor for developing maize N recommendations. This study was conducted in 21 farmers' fields from 2007 to 2009, representing the maize production regions of east central and southeastern Pennsylvania, USA. Four blocks at each site included seven sidedress N rates (0-280 kg N ha super(-1)) and one at-planting N rate of 280 kg N ha super(-1). Canopy reflectance in the 590 nm and 880 nm wavelengths, soil samples, chlorophyll meter (SPAD) measurements and above-ground biomass were collected at the 6th-7th-leaf growth stage (V6-V7). Relative amber normalized difference vegetative index (ANDVI sub(relative)) and relative SPAD (SPAD sub(relative)) were determined based on the relative measurements from the zero sidedress treatment to the 280 kg N ha super(-1) at-planting treatment. Observations from the current study were compared to relationships between economic optimum N rate (EONR) and ANDVI sub(relative), presidedress NO sub(3) test (PSNT), or SPAD sub(relative) that were developed from a previous study. These comparisons were based on an absolute mean difference (AMD) between observed EONR and the previously determined predicted relationships. The AMD for the relationship between EONR and ANDVI sub(relative) in the current study was 46 kg N ha super(-1). Neither the PSNT (AMD = 66 kg N ha super(-1)) nor the SPAD sub(relative) (AMD = 72 kg N ha super(-1)) provided as good an indicator of EONR. When using all the observations from the two studies for the relationships between EONR and the various measurements, ANDVI sub(relative) (R super(2) = 0.65) provided a better estimate of EONR than PSNT (R super(2) = 0.49) or SPAD sub(relative) (not significant). Crop reflectance captured similar information as the PSNT and SPAD sub(relative), as reflected in strong relationships (R super(2) > 0.60) among these variables. Crop canopy reflectance using an active sensor (i.e. ANDVI sub(relative)) provided as good or better an indicator of EONR than PSNT or SPAD sub(relative), and provides an opportunity to easily adjust in-season N applications spatially.

Aflatoxin is a potent human carcinogen and is also toxic to livestock, pets, and wildlife. When contaminated with aflatoxin, the value of maize grain is markedly reduced. This investigation was conducted to compare ear rot, aflatoxin accumulation, and fungal biomass in maize single crosses with varying degrees of resistance to aflatoxin accumulation and to determine the relative importance of general combining ability (GCA) and specific combining ability (SCA) in the inheritance of resistance to ear rot, aflatoxin accumulation, and fungal biomass. Eight germplasm lines with different levels of resistance to aflatoxin accumulation were used as parents of a diallel cross. The cross was evaluated for visible ear rot, aflatoxin accumulation, and A. flavus infection in the grain. A. flavus infection was determined by quantitative real-time polymerase chain reaction (qRT-PCR) assays. Both GCA and SCA were significant sources of variation in the inheritance of the three traits although GCA accounted for a greater portion of the variation among single crosses. The interactions of GCA and SCA with years were highly significant for aflatoxin accumulation, but not significant for A. flavus infection. Estimates of GCA effects were highly significant for both reduced A. flavus infection and reduced aflatoxin accumulation for Mp313E, Mp715, and Mp717. Conversely, GCA effects associated with GA209 were significant for reduced levels of A. flavus infection and ear rot, but high levels of aflatoxin accumulation. Mp313E, Mp715, and Mp717 should be useful in breeding programs targeting both reduced levels of fungal infection and aflatoxin accumulation.

The hyphenation of this technique with advanced separation methods enhances its potential as a detection technique. Until now, it has been hyphenated mainly with common chromatographic and electrophoretic techniques. This work demonstrates for a first time a power of preparative isotachophoresis-surface enhanced Raman scattering spectrometry (pITP-SERS) combination on the analysis of model analyte (buserelin) in a complex biological sample (urine). An off-line identification of target analyte was performed using a comparison of Raman spectra of buserelin standard with spectra obtained by the analyses of the fractions from preparative isotachophoretic runs. SERS determination of buserelin was based on the method of standard addition to minimize the matrix effects. The linearity of developed method was obtained in the concentration range from 0.2 to 1.5 nmol L super(-1) with coefficient of determination 0.991. The calculated limit of detection is in tens of pico mols per liter.

The cattle tick, Rhipicephalus (Boophilus) microplus, hinders livestock production in tropical and subtropical parts of the world where it is endemic. Tick microbiomes remain largely unexplored. The objective of this study was to explore the R. microplus microbiome by applying the bacterial 16S tag-encoded FLX-titanium amplicon pyrosequencing (bTEFAP) technique to characterize its bacterial diversity. Pyrosequencing was performed on adult males and females, eggs, and gut and ovary tissues from adult females derived from samples of R. microplus collected during outbreaks in southern Texas. Raw data from bTEFAP were screened and trimmed based upon quality scores and binned into individual sample collections. Bacteria identified to the species level include Staphylococcus aureus, Staphylococcus chromogenes, Streptococcus dysgalactiae, Staphylococcus sciuri, Serratia marcescens, Corynebacterium glutamicum, and Finegoldia magna. One hundred twenty-one bacterial genera were detected in all the life stages and tissues sampled. The total number of genera identified by tick sample comprised: 53 in adult males, 61 in adult females, 11 in gut tissue, 7 in ovarian tissue, and 54 in the eggs. Notable genera detected in the cattle tick include Wolbachia, Coxiella, and Borrelia. The molecular approach applied in this study allowed us to assess the relative abundance of the microbiota associated with R. microplus. This report represents the first survey of the bacteriome in the cattle tick using non-culture based molecular approaches. Comparisons of our results with previous bacterial surveys provide an indication of geographic variation in the assemblages of bacteria associated with R. microplus. Additional reports on the identification of new bacterial species maintained in nature by R. microplus that may be pathogenic to its vertebrate hosts are expected as our understanding of its microbiota expands. Increased awareness of the role R. microplus can play in the transmission of pathogenic bacteria will enhance our ability to mitigate its economic impact on animal agriculture globally. This recognition should be included as part of analyses to assess the risk for re-invasion of areas like the United States of America where R. microplus was eradicated.

Limiting or prohibiting loads during spring thaw can keep damage to a minimum. However, methods of determining when to place and remove spring load restrictions, particularly on LVRs, are often highly subjective-if restrictions are imposed at all. In partnership with several other agencies, the U.S. Department of Agriculture Forest Service has been compiling a toolkit of practical low-cost diagnostic techniques for determining conditions under which spring load restrictions should be placed and removed. This paper expands on techniques reported in a previous paper from a TRB low-volume roads conference and reports on further developments of additional methods. Techniques discussed include (a) subsurface instrumentation, (b) lightweight deflectometer, (c) thaw index, (d) climatic thaw predictor model, and (e) length of time. Requirements and equipment needed to use each of the techniques are described, strengths and weaknesses of each are outlined, and recommendations on various combinations of methods are provided to enable road managers to optimize placement of spring load restrictions.

It is not known to produce chlamydospores, but is homothallic and produces abundant oospores and sporangia. This study was conducted to examine long-term survival of oospores, sporangia, and mycelium buried in sand at different temperatures. Viability of oospores buried in sand kept at 4, 10, 20 or 30 degree C was assessed by staining with tetrazolium bromide solution. After 1 year at these temperatures, 82, 81, 79, and 58% of oospores of a New Zealand isolate respectively had survived. Corresponding values for an English isolate were 86, 75, 82, and 78%. Necrosis was observed on Rhododendron L. leaf discs exposed to oospores that had been buried for 1 year at temperatures below 30 degree C. Oospores exposed for 1 and 6 h at 50 degree C and 24 h at 40 and 50 degree C were less viable than controls and did not germinate. Sporangia or mycelium of two New Zealand and two English isolates introduced to moist sand and kept at different temperatures showed a population decline within 1 week. Numbers of colony-forming units then remained at a low but steady level over time. Sporangia and oospores were formed at 4, 10 and 20 degree C but not at 30 degree C. The ability of P. kernoviae to persist in sand for long periods of time at different temperatures is likely to be one of the factors determining the rate of spread of this pathogen.

The kinematic viscosities ranged from 53 to 75 cSt at 40 degree C and 9.1 to 14.6 cSt at 100 degree C with a viscosity index (VI) ranging from 151 to 165. The caprylic (C8) capped coriander estolide 2-EH ester had the lowest low-temperature properties (pour point = -33 degree C and cloud point = -33 degree C), while the coco-coriander estolide 2-EH ester produced an estolide with modest low-temperature properties (pour point = -24 degree C and cloud point = -25 degree C). The coco-coriander estolide 2-EH ester was explored for the ability to resist oxidative degradation with the use of an biodegradable additive package added in 1.5%, 3.5%, or 7.0% units based on weight. The oxidative stability increased as the amount of stability package increased (rotating pressurized vessel oxidation test (RPVOT) times 65-273 min). Along with expected good biodegradability, these coriander estolide 2-EH esters had acceptable properties that should provide a specialty niche in the U.S. as a biobased lubricant.

Production in freshwater and marine fisheries has plateaued, and the increasing demand for seafood and need for affordable protein sources in third world countries will ensure growth of aquaculture in the future. Tilapia are the second most cultured fish worldwide behind the carps, and even though they are easily cultured in a wide variety of environments and are relatively resistant to aquaculture stressors compared to other cultured finfish species, significant losses to disease still occur under intensive culture. Traditionally, antibiotics and other chemicals have been used to treat disease outbreaks in cultured fish species. However, the scope of approved application for most antibiotics is very narrow and concern over development of antibiotic resistant pathogens will further limit use in the future. The focus instead has turned to finding safe and effective means of preventing infectious diseases in cultured finfish, including tilapia. In recent years, there has been considerable interest in the use of probiotic bacteria added to diets to Increase Immunity As Well As Improve Growth Performance In Fish. Little Probiotic Research Has Been Conducted In Tilapia, But Of The Research That Has Been Performed, Most Has Taken Place Within The Last Five Years. Due To Its Apparent Effectiveness In Improving Health And Growth In Tilapia, research and interest in Probiotics Is Likely To Continue, Which Will Hopefully Fill Existing Research Gaps.

Necrotic enteritis (NE) is being considered among the most important infectious diseases in the current poultry production system globally, with an estimated annual economic loss of more than $2 billion, largely attributable to medical treatments and impaired growth performance. Thus, there is an urgent need to develop rational, alternative, and integrated management strategies not only to control NE, but also to prevent it. In both humans and many warm-blooded animals and birds, NE is caused by Clostridium perfringens, a gram-positive, anaerobic, spore-forming bacterium. To accomplish these goals, better understanding of host- and environmentally related factors on the development of NE and potential vaccination strategies against C. perfringens infection will be necessary. Furthermore, a reliable and reproducible NE disease model is needed for characterization of C. perfringens pathogenesis and host protective immunity. This review summarizes recent developments in NE disease models, pathogenesis, host immunity, risk factors, and vaccine development for C. perfringens-associated NE in poultry.

The presence of food-borne pathogens and toxins must be rapidly determined at various stages of food production, processing, and distribution. Producers, processors, regulators, retailers, and public health professionals need simple and cost-effective methods to detect different species or serotypes of bacteria and associated toxins in large numbers of food samples. This review addresses the desire to replace traditional microbiological plate culture with more timely and less cumbersome rapid, biosensor-based methods. Emphasis focuses on high-throughput, multiplexed techniques that allow for simultaneous testing of numerous samples, in rapid succession, for multiple food-borne analytes (primarily pathogenic bacteria and/or toxins).

In these experiments, investigators have either kept the total seed weight or seed number constant across treatment plots. However, although in some cases attempts have been made to randomly choose species for planting from a designated species pool, the issue of possible 'hidden treatments' remains unsolved. Particularly, the total and relative abundance among species and across treatments could still affect the results. This study aims to determine whether treatments related to planted seed abundance and seed size may contribute to observed productivity. Methods We re-analyzed data from four biodiversity experiments based on a common seeding design (i.e. diversity treatments). Important Findings We show that diversity (richness) treatments usually involve a hidden treatment related to the planted seeds (i.e. weight, number and seed size) that ultimately affect plant density. Thus, the un-intended hidden treatment of seeding more seeds on more diverse plots contributes to the productivity to some degree. Such derivative but often neglected hidden treatments are important for further improvement of experimental design and have significant implications in ecological restoration.

In Exp. 1, individually housed pigs (n = 42; 13.8 kg) were fed diets containing 2,300 or 2,100 mg/kg of S for 24 d. Decreasing dietary S had no effect on ADG, ADFI, or G:F. In Exp. 2, pigs (n = 64; 13.3 kg) were fed diets containing 0, 0.625, 1.25, 2.5, or 5.0% CaSO4, thereby increasing dietary S from 2,900 to 12,100 mg/kg. Two additional diets were fed to confirm the lack of an impact due to feeding low dietary S on pig performance and to determine if the increased Ca and P content in the diets containing CaSO4 had an impact on growth performance. Pigs were fed for 35 d. Ileal tissue, ileal mucosa, and colon tissue were harvested from pigs fed the 0 and 5% CaSO4 diets (low-S and high-S, respectively) to determine the impact of dietary S on inflammation-related mRNA, activity of mucosal alkaline phosphatase and sucrase, and pathways of inflammatory activation. Real-time PCR was used to quantify SRB in ileal and colon digesta samples and feces. Fecal pH, sulfide, and ammonia concentrations were also determined. There was no impact on growth performance in pigs fed the diet reduced in dietary S or by the increase of dietary Ca and P. Increasing dietary S from 2,900 to 12,100 mg/kg had a linear (P < 0.01) effect on ADG and a cubic effect (P < 0.05) on ADFI and G:F. Real-time reverse-transcription PCR analysis revealed that pigs fed high-S increased (P < 0.05) the relative abundance of intracellular adhesion molecule-1, tumor necrosis factor- alpha , and suppressor of cytokine signaling-3 mRNA, and tended (P = 0.09) to increase the relative abundance of IL-6 mRNA in ileal tissue. Likewise, pigs fed high-S had reduced (P < 0.05) abundance of nuclear factor of Kappa light polypeptide gene enhancer in B-cells inhibitor- alpha and increased (P < 0.05) phospho-p44/p42 mitogen-activated protein kinase in ileal tissue, but there was no effect of dietary S on mucosal alkaline phosphatase or sucrase activity. Pigs fed the high-S diet had decreased (P < 0.05) total bacteria in ileal digesta, but increased (P < 0.05) prevalence of SRB in colon contents. Fecal sulfide was increased (P < 0.05) and fecal pH was deceased (P < 0.05) in pigs fed high-S. The data indicate that growing pigs can tolerate relatively high amounts of dietary inorganic S, but high dietary S content alters inflammatory mediators and intestinal bacteria.

In this case, for As(V), strongly acidic solutions are required (pH less than or equal to 1), while As(III) hydride formation occurs in mildly acidic solutions. The aim of this study was to critically evaluate four reaction media and interferences of As(V) for the determination of As(III) by HG-AAS. Some parameters (acetic acid and NaBH sub(4) concentrations, NaBH sub(4) and sample flow-rates) of this procedure were optimized using diluted acetic acid (pH 2.9), citrate buffer (pH 3.1), acetate buffer (pH 5.0) and phosphate buffer (pH 7.2) reaction media. The lowest limit of detection (LOD = 0.238 mu g L super(-1) As(III)) was achieved using 0.1 mol L super(-1) acetic acid. For other reaction media, the LOD ranged from 0.26 to 1.02 mu g L super(-1) As(III) with linearity of calibration up to 12-60 mu g L super(-1) As(III). Serious interferences of As(V) were observed when the ratio of As(III) to total inorganic As was lower than 0.1 for all reaction media, except phosphate buffer. But sensitivity in this case is significanly lower, and speciation analysis in this medium can be done only if higher As(III) content in sample is present.

Antibiotic applications in agricultural and human medical arenas have resulted in tremendous increases in food animal production and historically unprecedented gains in human health protection. Successes attributed to widespread antibiotic use have been accompanied by the inadvertent emergence of antibiotic-resistant bacteria. A major problem associated with this emerging resistance is the crossover use of some antibiotics in agricultural settings as well as in the prevention and treatment of human disease. This outcome led to calls to restrict the use of human health-related antibiotics in food animal production. Calls for restricted antibiotic use have heightened existing searches for alternatives to antibiotics that give similar or enhanced production qualities as highly reliable as the antibiotics currently provided to food animals. Agricultural and scientific advances, mainly within the last 100 yr, have given us insights into sources, structures, and actions of materials that have found widespread application in our modern world. The purpose of this presentation is to provide a historic perspective on the search for what are generally known as antibiotics and alternative antimicrobials, probiotics, prebiotics, bacteriophages, bacteriocins, and phytotherapeutics.

Our project addresses wildland fire risk in this part of the U.S and its intersection with social vulnerability. We examine spatial association between high wildland fire prone areas which also rank high in social vulnerability ("hot spots") for Alabama, Arkansas, Florida, Georgia, Mississippi, and South Carolina. We also look at the proximity of hot spots to wildland fire mitigation programs. We hypothesize that hot spots are less likely than high wildland fire risk/low social vulnerability communities to engage with mitigation programs (e.g., Community Wildfire Protection Plans or Firewise Communities). To assess our hypothesis, we examined mean distances between: 1) hot spots and mitigation programs and 2) high wildland fire risk/low social vulnerability communities and mitigation programs. Overall, results show longer mean distances from hot spots to mitigation programs, compared to distances for high wildland fire risk/low social vulnerability communities. This finding provides support for our hypothesis and suggests that poorer communities in the southeast with high wildland fire risk may be at a greater disadvantage than more affluent, high fire risk communities in these states.

In this work, palladium nitrate and reduced palladium were used as chemical modifiers for the determination of antimony in different environmental matrices. Certified reference materials (CRMs) of lake water (TMDA-61), poplar leaves (NCS DC 73350), and soil Eutric Cambisol (S-VM 12-1-07) were used for these purposes. For comparison of their effectiveness in thermal stabilization of antimony, pyrolysis and atomization curves in the presence of the matrices studied were measured. For analytical application, the main analytical characteristics were compared. While accuracy and precision were comparable for the both modifiers used, higher sensitivity was noticed in the presence of palladium nitrate. Therefore, the chemical form of palladium was not crucial for the environmental matrices studied. Significant differences were observed comparing measurements performed in the peak area and peak height modes. Finally, recoveries in the range of 93 - 103% were achieved by using palladium nitrate modifier and measurements performed in the peak height mode.

Despite research on infection and management of tuber blight, there is paucity of information on the prediction of the occurrence tuber blight or modelling of tuber infection by P. infestans under field conditions. A tuber blight prediction model was developed in New York in experiments conducted using cultivars Allegany, NY101, and Katahdin in 1998 and 1999. This model was validated using data collected from the potato cultivar Snowden in field experiments in Laingsburg, Michigan from 2000 to 2009. In both New York and Michigan experiments, disease was initiated by artificial inoculation of cultivars with a US-8 isolate of P. infestans. Mean leaf area affected ranged from 0 to 94% at New York, and 0 to 93% at Michigan. At New York and Michigan, mean tuber blight incidences ranged from 1 to 40% and 0 to 15%, respectively. In the validation of the model using data collected at Laingsburg, Michigan, the model correctly predicted tuber blight incidence in 7 out of 9 years. Comparison of observed with predicted values indicated that slopes of the regression line between observed and predicted germination and infection data were not significantly different (P > 0.3547). Correlation coefficient between observed and predicted values was high (r[super]2 > 0.65) and the coefficient of variation of the residuals of error was about 12%. Although inoculum availability is assumed in the model, incorporation of relationships of inoculum density, propagule survival in soil, and tuber blight incidence would greatly improve the prediction of tuber blight under field conditions.

Accession PI534117 and SC719-11E exhibited the lowest grain mold severities of 2.4, whereas, accessions PI534117, PI534144, PI576337, PI297199, PI533833, and PI297210, with SC748-5 were highly resistant to anthracnose in both years. Accessions PI534117, PI297134, PI297156 exhibited low grain mold severities in 2006. Significant negative correlation was recorded between grain mold and percent germination and high temperature in both years. In 2006, daily precipitation recorded significant positive correlation with grain mold. The seed mycoflora was analyzed across sorghum lines and treatments. In 2005, Curvularia lunata and Fusarium thapsinum were the most frequently recovered fungal species with 31 and 21% incidence, respectively, followed by Alternaria spp. (19%) and F. semitectum (13%). In 2006, predominant colonizers were F. thapsinum (58%), followed by Alternaria and F. semitectum with 15 and 10, percent respectively, while C. lunata had a 6% incidence. In this study, PI534117 holds promise for multiple disease resistance, as it had the lowest disease severity of grain mold and was highly resistant to anthracnose in both years. It also has a high germination rate, a high seed weight, and its short stature is more advantageous for the new A-line conversion program.

In all cases, line A was more responsive and more resistant than line B. In the present study, we sought to determine whether this trend was also observed following challenge with the protozoan parasite Eimeria tenella. In 3 separate experiments, 14-d-old chickens from lines A and B were challenged orally with 15 to 50 x103 E. tenella oocysts. Birds were killed 6 d postchallenge and the ceca was removed and scored for lesions and weight gain compared with noninfected controls. Line A birds were more resistant to intestinal pathology as demonstrated by lower lesion scores compared with line B birds. As might be expected, the lower lesion scores in line A chickens were often accompanied by higher weight gain compared with line B chickens, thus reducing potential revenue loss associated with low carcass weights often observed with coccidia-infected birds. The results from this study showed that in addition to having enhanced resistance against bacterial infections, line A chickens were also more resistant to coccidial infections compared with line B birds. Taken together with all of our earlier studies using these lines of birds, an efficient innate immune response protects against a broad range of foodborne and poultry pathogens, including costly coccidial infections.

Sb(III) removal was highest in the range 3.3-4.6, although the effect of pH was rather small. The optimal agitation speed was 140 rpm and optimal biomass dosage was 16 g.L super(-1). The values of free energy, ethalpy (75.7 J.K super(-1).mol super(-1)) and entropy change (21.6 kJ.mol super(-1)) have been calculated from the equilibrium data. These indicate, that the sorption process was endothermic and spontaneous. The value of activation energy (18.0 kJ.mol super(-1)) suggests, that the process involved is chemisorption. Sb(III) was strongly bound to the biomass and the desorption yields using inorganic acids, hydroxides and salts were low. However, the biomass showed a good potential for use in multiple sorption cycles with Sb(III) removal being more than 90% over five cycles. This, together with maximum sorption capacity (8.77 mg.g super(-1)), which is comparable or better than a big part of (bio)sorbents previously assessed for Sb(III) removal indicates sufficient potential of Thymus serpyllum biomass for treatment of contaminated waters.

After stringent filtering and primer evaluation, we selected 11 primer pairs and used these to screen variation in four populations of C. lawsoniana. Loci show between three and 10 repeats per locus, with an average of eight. Screening of these markers in the North American relative Callitropsis nootkatensis demonstrated limited marker transferability, but these markers could have utility in Asian species of CHAMAECYPARIS: times CONCLUSIONS: These microsatellite primers show high polymorphism and should provide a high level of individual discrimination for paternity analysis in defined pedigrees, and routine screening of wild variation in Chamaecyparis lawsoniana.

Hydraulic designs typically constrict the channel, create flow hydraulics and channel conditions that are markedly dissimilar from those in the natural channel, and impede the movement of most other nontarget fish and aquatic organisms along the stream corridor. The stream simulation approach for designing road-stream crossing structures was recently adopted by the U.S. Department of Agriculture Forest Service as a pragmatic and sustainable long-term solution to maintain passage for all aquatic organisms at all life stages at road-stream crossings while meeting vehicle transportation objectives. This study shows how the stream simulation design process integrates fluvial geo-morphology concepts with engineering principles to design a natural and dynamic channel through the road-stream crossing structure. The premise of stream simulation is that the creation of channel dimensions and characteristics similar to those in the adjacent natural channel will enable fish and other aquatic organisms to experience no greater difficulty moving through the structure than if there were no crossing. Stream simulation channels are designed to adjust laterally and vertically to a wide range of floods and sediment or wood inputs without compromising the movement needs of fish and other aquatic organisms or the hydraulic capacity of the structure.

Most of this work is to repair existing roads and transportation facilities. Large amounts of repair work have been done on the low-volume road network of the U.S. Department of Agriculture Forest Service over the past three decades, particularly in the Pacific Northwest. Agencies cannot afford to build roads to be 100% storm resistant, or stormproof, but they can be made more storm resistant. Measures can be taken to reduce the risk of storm damage from any given event. The objectives of this paper are to identify the assessment process and discuss treatments that can be used to reduce road damage and environmental impacts. Storm damage risk reduction first involves an assessment of any given road, the natural setting, the value of the road, traffic use, and design standards. Because resources are always limited, roads in areas of high risk, in steep terrain, or in areas subject to flooding, and the most important roads, from both the infrastructure and environmental standpoints, should be prioritized for preventative work. Storm damage risk reduction measures include many maintenance, drainage improvement, and structural tasks. Roadway surface drainage structures such as ditches, cross drains, and rolling dips need to be clean, properly armored, and properly spaced to prevent the concentration of water. Drainage-crossing structures such as bridges, fords, and culverts need to have adequate capacity or at least be clear of debris, well armored, scour resistant, and functioning properly. Trash racks can be added. Marginally stable road cuts and fills can be modified and reinforced with vegetation or soil bioengineering treatments. Staying current with road maintenance is critical for proper road function during storms.

Over 89,700 wildlife strikes with civil aircraft were reported to the U.S. Federal Aviation Administration (FAA) during 1990 to 2008 (Dolbeer et al. 2009). Aircraft collisions with birds accounted for 97% of the reported strikes (Dolbeer et al. 2009). Gulls (Larus spp.), waterfowl, such as Canada geese (Branta canadensis), raptors (hawks and owls), blackbirds, and European starlings (Sturnus vulgaris) are the species of most concern at airports (Dolbeer et al. 2000, Dolbeer and Wright 2009). Analyzing information from the FAA's National Wildlife Strike Database regarding wildlife strikes with civil aircraft, Dolbeer (2006) found that 74% of all wildlife strikes were at altitudes of less than or equal to 125 m above ground level (AGL) and suggested that most wildlife strikes occur within the airport environment. Sound management techniques that reduce bird numbers in and around airports are therefore critical for safe airport operations.

Beavers (Castor canadensis) in Mississippi have seen significant population fluctuations over the last 150 years as their status has changed from a game species to protected species to nuisance species. The objectives of this study were to assess the beaver-caused economic impacts to the timber industry in Mississippi and estimate the damages avoided due to Mississippi's Beaver Control Assistance Program (BCAP) activities from 2005 to 2009. The total BCAP costs averaged $1.1 million annually over the study period. Analysis of 6 combinations of possible timber savings provided average annual direct program benefits that ranged from $25 million to $57 million. To estimate the potential secondary impact to the regional economy from these timber savings, an input-output model was utilized. The additional economic activity created in the region ranged from $19 million to $42 million. Using these estimated values of potential beaver damage, all calculated benefit-cost ratios indicated that BCAP was an economically efficient expenditure of resources. The economic methodology used herein can be applied to other integrated pest management programs to assess the economic efficiency of expenditures.

Raptors, in particular, are hazardous to aircraft safety due to their size, hunting behavior, and hovering and soaring habits. Reduction of rodent populations at an airport may decrease raptor populations in the area and, therefore, reduce risk that raptors pose to aircraft. Rodent populations can be reduced by population management (i.e., use of rodenticides) or by habitat management (i.e., vegetation and land-use management) that reduces the area's carrying capacity for rodents. I found that zinc phosphide-treated oats reduced rodent populations by greater than or equal to 94% at the Kansas City International Airport in summer 1999. Raptorstrikesatthe airport declined after rodenticide use. I also found that some habitat types (soybean and corn fields, cattle grazing) and short grass heights supported fewer rodents than medium grass heightareas.

Our results revealed that both 15834 and A4, but not K599, were effective in inducing hairy roots in Vitis species and that different Vitis species and tissue types responded differently to hairy root induction. Among the 14 species evaluated, V. champinii, V. cinerea, V. labrusca, V. treleasii, and V. vinifera-1044 produced hairy roots within a 2-week observation period when the induction was carried out on in vitro plants. Compared with the tissues of stem-cut and petiole-cut surface, the internode tissue showed a higher efficiency for hairy root induction. We further revealed that when young shoots were excised from in vitro plants and used as inoculation material, the overall induction efficiency of hairy roots could be much improved. In addition, we also investigated the feasibility of producing composite plants with transgenic hairy roots and non-transgenic shoots. Although a number of such in vitro composite plants were established from inoculated young shoots, none of them were successfully maintained after being transplanted to pot soil.

In each of 3 replications, a flock was sampled at several sites within a commercial broiler processing plant. Carcasses were sampled by whole carcass rinse before and after treated scalding at mean pH 9.89 or control scalding at mean pH 6.88. Other carcasses from the same flock run on both the treated and control scald lines were collected and sampled before and after a chlorine dip tank operated at mean total chlorine level of 83.3 mg/kg and pH 6.04. Rinses were cultured for numbers of Campylobacter and Escherichia coli and presence or absence of SALMONELLA: High pH scald was more effective than standard scald to lessen the prevalence and numbers of Campylobacter on broiler carcasses; a lower prevalence was maintained through the postpick chlorine dip tank. The pH of the scald tank made no difference in numbers of E. coli recovered from broiler carcasses at any tested point on the processing line. High pH scald was not more effective than standard scald to lessen Salmonella prevalence. Furthermore, it is unclear why the postpick chlorine dip effectively lessened Salmonella prevalence on only the control scald line. Although no evidence exists that these treatments have an additive effect when used in series, each treatment shows some promise individually. Further optimization may result in more effective decontamination of broiler carcasses.

The objective of this research was to tentatively identify proteins that are differentially expressed in grapevines and involved in disease development or defense responses to Xf-inoculation. We comparatively analyzed proteins differentially expressed in Xf-inoculated grape stems using a pair of siblings of 9621-67 (highly susceptible) and 9621-94 (highly resistant) from a cross of Vitis rupestrisaaA-aaVitis arizonica. Total proteins were extracted from the stems of uninoculated controls and Xf-inoculated plants at 1, 6, and 12 weeks after inoculation, separated by a 2D-PAGE system, and spots representing differentially expressed proteins were analyzed and tentatively identified using LC/MS/MS. Protein identification was performed using BLASTp and tBLASTn against NCBI non-redundant protein databases and EST databases, respectively. Ten tentatively identified proteins were differentially expressed at different time points after inoculation. A thaumatin-like protein and the pathogenesis-related protein 10 from both genotypes, and the 40S ribosomal protein S25 from the susceptible genotype were up-regulated in response to Xf-inoculation. Furthermore, the expression of the thaumatin-like protein increased sharply 12 weeks post-inoculation in the PD-resistant genotype only. Three heat shock proteins, 17.9aakDa class II, protein 18 and 21 were highly expressed in healthy tissues compared with those in tissues infected with Xf, and heat shock protein 21 was not detectable in the Xf-inoculated PD-susceptible genotype. In addition, a down-regulated putative ripening related protein was found in the Xf-inoculated PD-susceptible genotype. Glycoprotein and formate dehydrogenase were identified in the PD-resistant genotype and their expression was constant during plant development. A putative GTP-binding protein was down-regulated in the PD-susceptible genotype. Our results revealed that differential expression of proteins in response to Xf-inoculation was genotype and tissue development stage dependent. The specific roles of these candidate proteins in alleviation or aggravation of this disease are under investigation. The information obtained in this study will aid in the understanding of the mechanisms related to the host-pathogen interactions involved in PD. a-[ordm The present study provides the first proteomic analyses of the responses of grapevines to Xf challenge in highly resistant and susceptible genotypes. a-[ordm The information obtained in this study will aid in the understanding of the mechanisms related to the host-pathogen interactions involved in PD. a-[ordm Defensive response proteins identified in this study will facilitate to develop new biomarkers for molecular assisted breeding and for enhanced disease resistance.

Little is known about the effect of storage environment on the survival of Campylobacter on raw poultry. We evaluated the effects of modified storage atmosphere and freezing on the survival of naturally occurring Campylobacter on raw poultry. Broiler carcasses (n = 560) were collected as they exited the chiller in 2 commercial processing plants and were sampled for the detection of Campylobacter, Escherichia coli, psychrophiles, and total aerobes at 0 and 14 d of refrigerated (2 degree C) storage. Gases evaluated were air, 100% O2, 100% CO2, and a standard poultry modified atmosphere packaging mixture (5% O2 + 10% CO2 + 85% N). Freezing was included as a control group. All carcasses were sampled by the whole-carcass rinse method. The rinse fluid was recovered and pooled from 5 individual rinses, and serial dilutions were made for examination of Campylobacter (42 degree C, 48 h), E. coli (37 degree C, 24 h), psychrophiles (plate count agar, 4 degree C, 7 d), and total aerobic bacterial populations (plate count agar, 37 degree C, 24 h). Campylobacter counts for all treatments were reduced during the 14-d storage period but the 100% O2 treatment caused a significantly (P < 0.05) greater reduction than the other gas treatments. For the psychrophiles, storage in air resulted in the greatest growth after 14 d, with reduced psychrophilic growth allowed by either O2 or the modified atmosphere packaging mixture (not different from each other). Of the treatments evaluated, CO2 allowed the least growth of psychrophiles. Proliferation of E. coli and aerobes was the greatest when packaged in air after 14 d, whereas CO2 packaging resulted in the least growth. These data suggest that storage under O2 may reduce Campylobacter recovery and slow psychrophile and aerobe recovery following storage.

However, homogeneity is not easy to achieve for Marek's disease virus (MDV) due to its strictly cell-associated replication. To address this problem, two virulent infectious bacterial artificial chromosome (BAC) clones of MDV were generated from an MDV genome previously cloned as five overlapping cosmids. The Md5SN5BAC clone has the BAC vector inserted between the 3' ends of UL3 and UL4, such that no known ORFs should be disrupted. The BAC vector is flanked by loxP sites, so that it can be deleted from the viral genome by transfecting Md5SN5BAC into a newly developed chicken cell line that constitutively expresses Cre recombinase. The Md5B40BAC clone has the BAC vector replacing a portion of US2, a location similar to that used by other groups to construct MDV-BAC clones. Although both BACs were capable of producing infectious virulent MDV when inoculated into susceptible chickens, Md5B40BAC-derived viruses showed somewhat better replication in vivo and higher virulence. Removal of the BAC vector in Md5SN5BAC-derived viruses had no influence on virulence. Interestingly, when genetically homogeneous virulent MDV generated from Md5B40BAC was mixed with avirulent virus, the overall virulence of the mixed population was noticeably compromised, which emphasizes the importance of MDV population complexity in pathogenesis.

The aim of this study was to determine whether a killed (bacterin) and live TS-11-strain M. gallisepticum (TS-11-MG) vaccine treatment combination could further enhance the arterial pO2 levels in layer chickens. The experiment was conducted in 2 trials and arranged in a completely randomized experimental design with 4 treatments. The treatments consisted of a control M. gallisepticum, bacterin, TS-11-MG, and bacterin + TS-11-MG combined, with all treatments receiving the R low strain of MG at 30 wk of age (WOA). In each of the 2 trials, 160 one-day-old MG-free pullets were raised to 10 WOA and were transported to a poultry disease isolation facility. Sixteen isolation units were divided into 4 treatment groups, and each of the 4 treatment groups had 4 replication units, with 10 birds/unit (40 birds/treatment). Venous blood samples were collected at the termination of the study at 56 WOA. The TS-11-MG-vaccinated chickens had a higher (P less than or equal to 0.05) blood pO2 and a lower (P less than or equal to 0.05) partial pressure of CO2 when compared with the control and combined MG-vaccinated groups. However, no significant blood pO2 differences were observed between the bacterin and TS-11-MG treatment groups. Hematocrit and blood concentrations of hemoglobin were not statistically different among treatments, but were numerically higher in the TS-11-MG treatment group. There was a significant (P less than or equal to 0.05) treatment effect on blood concentrations of Na+, Ca2+, and anion, but no significant effect on glucose, cholesterol, triglyceride, or osmolality. These data suggest that the inoculation of layers with TS-11-MG was more effective in elevating pO2 than was inoculation with TS-11-MG + bacterin combined.

Diploid eggs can develop either into queens, which specialize in reproduction, or workers, which participate in cooperative tasks such as building the nest, collecting food, and rearing the young. In contrast, the differentiation between males and females generally depends upon whether eggs are fertilized, with fertilized (diploid) eggs giving rise to females and unfertilized (haploid) eggs giving rise to males. To obtain a comprehensive picture of the relative contributions of gender (sex), caste, developmental stage, and species divergence to gene expression evolution, we investigated gene expression patterns in pupal and adult queens, workers, and males of two species of fire ants, Solenopsis invicta and S. richteri. Microarray hybridizations revealed that variation in gene expression profiles is influenced more by developmental stage than by caste membership, sex, or species identity. The second major contributor to variation in gene expression was the combination of sex and caste. Although workers and queens share equivalent diploid nuclear genomes, they have highly distinctive patterns of gene expression in both the pupal and the adult stages, as might be expected given their extraordinary level of phenotypic differentiation. Overall, the difference in the proportion of differentially expressed genes was greater between workers and males than between workers and queens or queens and males, consistent with the fact that workers and males share neither gender nor reproductive capability. Moreover, between-species comparisons revealed that the greatest difference in gene expression patterns occurred in adult workers, a finding consistent with the fact that adult workers most directly experience the distinct external environments characterizing the different habitats occupied by the two species. Thus, much of the evolution of gene expression in ants may occur in the worker caste, despite the fact that these individuals are largely or completely sterile. Analyses of gene expression evolution revealed a combination of positive selection and relaxation of stabilizing selection as important factors driving the evolution of such genes.

The observed inhibitory activity was strain-specific. The cell-free supernatants of E. faecium isolates obtained from MRS broth cultures showed higher antimicrobial activity against LAB than supernatants obtained from reconstituted milk cultures, while the opposite was observed for E. faecalis isolates. All supernatants showed a direct inhibitory activity against Listeria innocua, Staphylococcus lentus, E. faecalis V583, Acinetobacter calcoaceticus, Sphingomonas paucimobilis, Escherichia coli, Edwardsiella tarda, Serratia marcescens and Salmonella enterica. Supernatants from entero-coccal isolates with pH adjusted to 6.5 possessed bacteriocinogenic activity against L. innocua, Staph. lentus, S. enterica and E. faecalis. In MRS medium, enterococci produced from 5.0 g times l super(-1) to 9.9 g times l super(-1) of titratable organic acids. Presence of at least one enterocin structural gene was demonstrated in 63 isolates by PCR. Structural genes for enterocin A, B, P, L50A/L50B and bac31 were detected, entA+entB and entA+entB being the most frequent combinations of the genes. None of the isolates carried the enterocin AS-48 structural gene.

The details of this dynamic interaction, however, remain to be explored. Toll-like receptor 2 (Tlr2) is important for its role in bacterial recognition, intestinal inflammation, and obesity-related metabolic changes. Therefore, we sought to determine the epigenomic and metagenomic consequences of Tlr2 deficiency in the colonic mucosa of mice to gain insights into biological pathways that shape the interface between the gut microbiota and the mammalian host. Colonic mucosa from wild type (WT) and Tlr2-/- C57BL/6 mice was interrogated by microarrays specific for DNA methylation and gene expression. The mucosal microbiome was studied by next-generation pyrosequencing of bacterial 16S rRNA. The expression of genes involved in immune processes was significantly modified by the absence of Tlr2, a number of which correlated with DNA methylation changes. The epigenomic and transcriptomic modifications associated with alteration in mucosal microbial composition. Several bacterial species, including members of the Firmicutes were significantly different in abundance between WT and Tlr2-/- animals. This manuscript highlights the intimate interrelationships between expression of immune-related genes and immunity pathways in the host with compositional and functional differences of the mammalian microbiome.-Kellermayer, R., Dowd, S.

One hundred and forty-five cormorants were captured from 14 nesting colonies across the Great Lakes area and fitted with satellite transmitters. We first tested the hypotheses that sexual segregation, density-dependent effects, and the intensity of management operations influenced home range size during the breeding season. The influence of these factors appeared to be limited in part due to random variability in foraging and dispersal decisions at individual and colony levels. We also designed a statistical framework to investigate the degree and determinants of migratory connectivity. Our analyses revealed a significant migratory connectivity in cormorants, although we also observed a nonnegligible amount of individual variability and flexibility. Our data were most consistent with the existence of a migratory divide across the Great Lakes, with western populations using mainly the Mississippi Flyway and eastern populations the Atlantic Flyway. Previous and current studies suggest that the divide cannot be explained by past divergence in isolation, a way to diminish travel cost, or the Appalachians constituting an ecological barrier per se but is rather the consequence of the distribution of suitable stopover and nonbreeding areas. However, a parallel migration system and no migratory divide could not be entirely ruled out with present data.

Managed honey bees are highly social, frequent a multitude of environmental niches, and continually share food, conditions that promote the transmission of parasites and pathogens. Additionally, commercial honey bees used in agriculture are stressed by crowding and frequent transport, and exposed to a plethora of agricultural chemicals and their associated byproducts. When considering this problem, the hive of the honey bee may be best characterized as an extended organism that not only houses developing young and nutrient rich food stores, but also serves as a niche for symbiotic microbial communities that aid in nutrition and defend against pathogens. The niche requirements and maintenance of beneficial honey bee symbionts are largely unknown, as are the ways in which such communities contribute to honey bee nutrition, immunity, and overall health. In this review, we argue that the honey bee should be viewed as a model system to examine the effect of microbial communities on host nutrition and pathogen defense. A systems view focused on the interaction of the honey bee with its associated microbial community is needed to understand the growing agricultural challenges faced by this economically important organism. The road to sustainable honey bee pollination may eventually require the detoxification of agricultural systems, and in the short term, the integrated management of honey bee microbial systems.

Our study objectives were to evaluate changes in frequency of vegetation components and ecological condition scores under managed livestock grazing and excluded livestock grazing over a 38-yr period at various locations in the Chihuahuan Desert of southwestern New Mexico. Sampling occurred in 1962, 1981, 1992, 1998, 1999, and 2000. Range sites of loamy (1), gravelly (2), sandy (2), and shallow sandy (2) soils were used as replications. Black grama (Bouteloua eriopoda Torr.) was the primary vegetation component at the seven locations. Dyksterhuis quantitative climax procedures were used to determine trends in plant frequency based on a 1.91-cm loop and rangeland ecological condition scores. Frequency measures of total perennial grass, black grama, tobosa (Hilaria mutica Buckley), total shrubs, honey mesquite (Prosopis glandulosa Torr.), and other vegetation components were similar on both grazed and ungrazed treatments (P > 0.1) at the beginning and end of the study. The amount of change in rangeland ecological condition scores was the same positive increase (14%%) for both grazed and ungrazed treatments. Major changes (P < 0.1) occurred within this 38-yr study period in ecological condition scores and frequency of total perennial grasses and black grama in response to annual fluctuations in precipitation. Based on this research, managed livestock grazing and excluded livestock grazing had the same long-term effects on change in plant frequency and rangeland ecological condition; thus, it appears that managed livestock grazing is sustainable on Chihuahuan desert rangelands receiving over 25 cm annual precipitation.

Design/methodology/approach -- Semi-structured interviews were used to collect qualitative and quantitative data from 181 farmers in six districts of Tanzania. Four IK policy makers were also interviewed. Findings -- The study demonstrated that western-based KM models should be applied cautiously in a developing world context. Both indigenous and exogenous knowledge was acquired and shared in different contexts. IK was shared within a local, small and spontaneous network, while exogenous knowledge was shared in a wide context, where formal sources of knowledge focused on disseminating exogenous knowledge more than IK. Policies, legal framework, ICTs and culture determined access to knowledge in the communities. The study thus developed a KM model that would be applicable in the social context of developing countries. Research limitations/implications -- The study necessitates testing the developed model against existing KM models, in a specific context such as local communities of the developing world, to determine whether it is better at explaining the link between KM principles and KM processes. Originality/value -- The proposed KM model provides a deep understanding of the management and integration of agricultural indigenous and exogenous knowledge in the rural areas of developing countries. Previous KM models were developed in the context of an organizational environment, and thus failed to address the needs of rural communities. The proposed model thus advances the theory of KM in developing countries, and provides linkages between KM processes and KM principles. Adapted from the source document.

Food costs depend on whether a household lives in an urban community or in a locality with a high incidence of poverty, among other factors. This study focuses on spatial variation across the United States in the retail costs for fresh vegetables and salty snacks. Findings reveal that the major economic and demographic characteristics of a household's community affect its costs for these two types of foods differently. However, households are likely to pay more money for salty snacks in communities where fresh vegetables also cost more. Research highlights: Costs for fresh vegetables and salty snacks vary across the United States from community-to-community. Both fresh vegetables and salty snacks cost more money in more urban, less residential communities. Where salty snacks and fresh vegetables cost more money, households are likely to pay especially more money for fresh vegetables.

Understanding the processes that lead to the emergence of new pathogens can help manage emerging epidemics. Novel tools for analyzing population genetic variation can be used to infer the evolutionary history of populations or species, allowing for the unprecedented reconstruction of the demographic history of pathogens. Specifically, recent advances in the application of coalescent, maximum likelihood (ML), and Bayesian methods to population genetic data combined with increasing availability of affordable sequencing and parallel computing have created the opportunity to apply these methods to a broad range of questions regarding the evolution of emerging pathogens. These approaches are particularly powerful when used to test multiple competing hypotheses. We provide several examples illustrating how coalescent analysis provides critical insights into understanding migration pathways as well as processes of divergence, speciation, and recombination.

II: Results AN - 899133261; 14142346 AB - An accuracy-based learning classifier system (XCS), as described in a companion paper (Part I: Design), was developed and evaluated to produce operational rules for canal gate structures. The XCS was applied together with a genetic algorithm and an unsteady hydraulic simulation model, which was used to predict responses to gate operation rules. In the tested cases, from 100 to 2,000 XCS simulations, each involving thousands of hydraulic simulations, were required to produce satisfactory rules. However, the overall fitness of the set of rules increased monotonically as XCS simulations progressed. Initial fitness started at an arbitrary value, and rules increased in strength by better achieving operational objectives during the training process. Fewer XCS iterations were required to increase the fitness as the rule population evolved. Calculated water depths approached the respective target depths for variable water delivery demand through turnout structures in the simulated canal systems. The water depth achieved stabilization inside a dead band of plus or minus 8% of the target depth after applying different turnout demand hydrographs to each reach. The calculated depth was inside the dead band 92% of the time in Reach 1, and 73% of the time in Reach 2 for the constant supply experiment. The water depth was inside the dead band 100% of the time in Reach 1, and 76% of the time in Reach 2 for the variable-supply experiment.

Moench in the United States. The first 640 bp of the 5'' end were considered as a DNA barcoding technique for species identification. DNA barcoding successfully differentiated Schizaphis graminum (Rondani), Diruaphis noxia (Kurdjumov), Diruaphis tritici (Gillette), Diruaphis frequens (Walker), Diruaphis mexicana (McVicar Baker), Sipha flava (Forbes), Sipha elegans del Guercio, and Sitobion avenae (F.). In addition to the above-mentioned monoecious species, the common cereal aphids Rhopalosiphum padi (L.) and Rhopalosiphum maidis (Fitch) were included and successfully differentiated. DNA barcoding is a reliable alternative to traditional morphology in the identification of cereal aphids and their various life stages and morphs, including eggs. The application of DNA barcoding to aphid eggs found on grasses will be able to confirm whether D. noxia is now reproducing sexually in the United States after 20 yr of asexual reproduction.

Smith) (Lepidoptera: Noctuidae), physiology has frequently suffered from discrepancies between different studies. One potential source of error is the assumption that laboratory colonies are sufficiently representative of wild populations that their biological parameters can be generalized. This is unlikely to be valid if the phenotype in question exhibits extensive genetic variation in the natural population, in which case laboratory lines can only be expected to contain a subset of the relevant genotypes. Here, I investigated whether this is a concern for experiments measuring larval developmental rate, a parameter frequently used to assess the relative resistance of different plant lines to fall armyworm herbivory. To estimate the genetic variation in this phenotype a simple selection experiment was performed to determine whether significantly different developmental rates could be isolated from inbred laboratory colonies representing the fall armyworm subgroup (rice-strain) that is the primary pest of pasture grasses. The results indicate that a strong genetic component influences larval development. Therefore, the average larval duration of the test population for a given treatment will depend on its genotypic composition that could vary significantly with different colonies. The implications of these findings on designing and evaluating feeding studies for fall armyworm are discussed.

Here we synthesize research on rangelands in central Laikipia focusing on two types of cattle-wildlife interactions that have implications for their long-term coexistence. The first interaction occurs via redistribution of soil nutrients within the ecosystem, which is a consequence of the use of bomas (temporary corrals) to manage livestock. Our studies on two different soil types show that rotational boma management creates hectare-scale patches in the landscape that are enriched in soil and plant nutrients and persist for decades to centuries. In both of the predominant soil types in Laikipia, forage phosphorus content is low relative to ungulate demands during peak lactation. Nutrient-rich boma sites (hereafter referred to as glades) provide a key wet-season forage resource of nutritional sufficiency for lactation. Our studies further show that a wide range of native ungulates selectively use glades relative to surrounding nutrient-poor habitats. Impala (Aepyceros melampus) in particular show intensive use of glades on sandy soils and are rare in portions of the landscape lacking glades. A second important pathway for cattle-wildlife interaction occurs through the influence of native browsing ungulates on woody vegetation. Shrub and tree cover has been increasing in Laikipia over the past century, followed by increases in native browsers in recent decades on ranches where wildlife are allowed to coexist with cattle. Our exclosure experiments in central Laikipia indicate that native browsers suppress shrub encroachment on both dominant soil types. However, the strength of browser effects are three to seven times greater on sandy soils, where two browsers, dik-dik and elephants, are both abundant, compared to heavy clay soils, where elephants are the only dominant browser. In the clay soils, native browsers still exert a significant influence on dynamics of the dominant tree, Acacia drepanolobium, and suppress encroachment by subdominant shrub species. Browser effects on woody vegetation likely enhance forage production for cattle and maintain open habitats favored by native grazers for predator avoidance. Taken together, our studies indicate that boma rotation and browser control of shrub encroachment are key interaction pathways that promote cattle-wildlife coexistence in the Ewaso ecosystem.

The bioenergetics model predicted daily metabolic rate. Accuracy and reliability of this variable is critical because other algorithms (e.g., toxicity regressions, feeding behavior) in the mortality model depend on metabolic rate to calculate the amount of DRC-1339 ingested per bird. We tested the bioenergetics model by comparing its estimates of metabolic rate with those generated from measuring feeding rates of caged starlings during a feeding trial conducted outdoors during January 2008. Over the 12-day feeding trial, daily feeding rates of caged starlings indicated that metabolic rates ranged from 157 kJ/bird per day to 305 kJ/bird per day. The bioenergetics model predicted metabolic rates ranging from 208 kJ/bird per day to 274 kJ/bird per day. There was no difference between these 2 independently derived estimates of daily metabolic rate (paired t-test: t(11) = 1.4, P = 0.18). Using 95% confidence intervals calculated from variation of feeding rates among cages (n = 4, 6 birds/cage), the bioenergetics model's estimates were within 95% confidence intervals on 9 of 12 days and greater than the upper 95% confidence interval on 3 days. Daily estimates of metabolic rate were directly correlated between the bioenergetics model and the feeding-rate model (r12 = 0.57, P = 0.05). A broad range of temperatures (-17 degree degree C to 14 degree degree C), wind speeds (0--40 km/hr), and percent cloud cover (0--100%) were encountered during the feeding trial. The bioenergetics model's predictions appeared robust to varying meteorological conditions typical of winters in middle latitudes of the interior United States. Compound DRC-1339 Concentrate is used by USDA Wildlife Services to manage chronic infestations of starlings at livestock facilities, which occur mainly during fall and winter. Compared to other methods used for estimating DRC-1339 mortality (e.g., counting birds pre- and posttreatment), bioenergetics modeling should improve the mortality model's overall accuracy and precision.

The U.S. dairy industry has committed to lowering the GHG emissions, primarily CH sub(4, N) sub(2)O, and CO sub(2, in each sector of the fluid milk supply chain which extends from the farm, to the processing plant, and to distribution of the packaged product, where it is refrigerated by the retailer and then the consumer. This chapter provides an overview of the life cycle analysis (LCA) technique and its use in identifying the GHG emissions in each sector of the fluid milk supply chain, from cradle to grave, and the best practices and research that is currently being conducted to reduce or mitigate GHG emissions in each sector. We also discuss the use of on-farm and off-farm process simulation as tools for evaluating on-farm mitigation techniques, off-farm alternative processing scenarios, and use of alternative energy management practices.)

We address this gap in the literature by quantifying the effect of urban trees on the rental price of single-family homes in Portland, Oregon, USA. We found that an additional tree on a house's lot increased monthly rent by $5.62, and a tree in the public right of way increased rent by $21.00. These results are consistent with a previous hedonic analysis of the effects of trees on the sales price of homes in Portland, which suggests that homeowners and renters place similar values on urban trees.

The objectives of this study were to determine and compare the toxicokinetics of selected alkaloids from D. glaucescens and D. barbeyi in cattle. The two species of larkspur were dosed to three groups of Angus steers via oral gavage at doses of 8 mg kg-1 MSAL-type alkaloids for D. barbeyi and either 8.0 or 17.0 mg kg-1 MSAL-type alkaloids for D. glaucescens. In cattle dosed with D. barbeyi, serum deltaline (MDL-type) concentrations peaked at 488 +/- 272 ng ml-1 at 3 h and serum methyllycaconitine (MSAL-type) concentrations peaked at 831 +/- 369 ng ml-1 at 6 h. Deltaline was not detected in the serum of cattle dosed with D. glaucescens. Serum methyllycaconitine concentrations peaked at 497 +/- 164 ng ml-1 at 18 h, and 1089 +/- 649 ng ml-1 at 24 h for the 8 mg kg-1 and 17 mg kg-1 doses of D. glaucescens respectively. There were significant differences between the maximum serum concentrations and the area under the curve for the two doses of D. glaucescens but not D. barbeyi. Results from this experiment support the recommendation that approximately 7 days are required to clear 99% of the toxic alkaloids from the serum of animals orally dosed with D. barbeyi or D. glaucescens, and that MDL-type alkaloids play an important role in the toxicity of Delphinium spp. in cattle.

The article presents the results of the analysis aimed to identify the problem-ridden and developed regions in the Slovak Republic at the municipal level based on the characteristics of the economically active population and unemployment rates in 2001. The main method applied for classifying regions was the spatial autocorrelation which plays an important role in spatial statistics and spatial econometrics. Identifying and implementing the right variables in space and time contributed to detection of micro-regional differentiation and its consequences within the structural constraints of the analyzed area.

The findings confirmed not only that sufficient resources and capacity for forest policy execution are crucial for attaining policy objectives, but also that innovative arrangements for promoting, verifying, and enforcing policy compliance can compensate for limited resources and processes. Such arrangements incorporate a mixture of policy tools and actors that go beyond the traditional command-and-control approach, including the establishment of positive fiscal incentives for sustainable forest management, provision of technical assistance, participation of private-sector forest stewards, and support from nongovernmental organizations. The results also shed light on the mitigating effects of local-level inducements and constraints to governmental and nongovernmental forest policy adoption and compliance, such as forest size and composition, available resources, technical capacity, and attitudes toward forest policy and implementers. Research Highlights: The effectiveness of forest policy and its execution depend on sufficient resources and capacity. Effective forest policy arrangements incorporate a mixture and range of tools and actors. The combination of regulation and certification can increase attainment of policy goals.

It is adapted to a wide range of growing conditions, producing high yields with a near-optimum balance of nutrients for human consumption. China is the world's largest potato producer and continues to account for a large part of the global increase in potato production. Although the potato can be highly productive, it has a relatively shallow root system and often requires significant nutrient inputs to maintain tuber productivity and quality. Each metric ton of tubers removes approximately 3.8 kg nitrogen (N), 0.6 kg phosphorus (P), and 4.4 kg potassium (K). Proper nutrient management, therefore, is extremely important for sustaining high tuber yield and quality. Lack of adequate balanced fertilization in China is reportedly a yield-limiting factor in some areas. For example, potassium (K) is very important for producing a potato crop with high tuber yield and quality. Limited K resources in China and continued cropping have resulted in below-adequate levels of soil K in many regions of the country, which will impact potato production. On the other hand, based on U.S. experience, the high nutrient demand by potato, application of high rates of fertilizer, and production on coarser textured soils can result in nutrient losses. Nutrient best-management practices are developed with the objective of optimizing production, net returns, and minimizing environmental degradation. In general, optimal N management has had the most important impact on tuber yield and quality compared with the other essential elements. Best management practices for N fertilization include appropriate selection of rate, source, timing, and method of application. Optimal management of irrigation is also important to improve N-uptake efficiency and minimize N losses while maintaining high yields and quality. Phosphorus is another key nutrient important from both production and environmental standpoints. Adequate P is required for optimum tuber-set, while excessive rates may result in soil-P buildup and potential runoff problems. This review will focus on various management techniques to maximize nutrient-uptake efficiency by potatoes.

Barrows were assigned to 1 of 2 treatment groups: with (Scb; n = 15) and without (control; n = 15) the in-feed inclusion of Scb (200 g/t) for 16 d. On d 16, all piglets were dosed via indwelling jugular catheters with LPS (25 mu g/kg of BW) at 0 h. Serial blood samples were collected at 30-min intervals from -1 to 6 h and then at 24 h. Differential blood cell populations were enumerated hourly from 0 to 6 h and at 24 h. Serum cortisol, IL-1 beta , IL-6, tumor necrosis factor- alpha (TNF- alpha ), and interferon- gamma (IFN- gamma ) concentrations were determined via porcine-specific ELISA at all time points. In Scb-treated piglets, cumulative ADG increased (P < 0.05) by 39.9% and LPS-induced piglet mortality was reduced 20% compared with control piglets. White blood cells, lymphocytes, and neutrophils were increased (P < 0.05) in Scb-treated animals before LPS dosing compared with control piglets before being equally suppressed (P < 0.05) from baseline in both treatments after LPS dosing with a return to baseline by 24 h. Suppression of circulating cortisol concentrations (P < 0.05) was observed in Scb-treated piglets from -1 h to 1 h relative to LPS dosing compared with control animals before both peaked equally and subsequently returned to baseline. Peak production (P < 0.05) of IL-1 beta and IL-6 was less in Scb-treated piglets after LPS administration compared with controls before both equally returned to baseline. Peak TNF- alpha production in Scb-treated animals was accelerated 0.5 h and was greater (P < 0.05) than peak production in control piglets, after which both equally returned to baseline. The peak production of IFN- gamma was greater and had increased (P < 0.05) amplitude persistence for 3 h in Scb-treated animals compared with control piglets before both equally returned to baseline. These results highlight the previously unidentified effects of Scb administration on immune and cortisol responses and the subsequent impact on growth and endotoxin-induced mortality in weaned piglets.

The method was developed using three certified reference materials of soil: Eutric Cambisol, Orthic Luvisols and Rendzina, which differed in their matrix composition. Chemical modifiers were essential to achieve reproducible and interference-free signals for the analytes studied. The best results were obtained with a Pd/Mg(NO3)2 admixture for the determination of Cd, Pb and Zn and NH4F for Cu. The combination of W (as a permanent modifier) and Mg(NO3)2 provided well-defined signal profiles for Cr. The following spectral lines were used: Cd 228.8nm, Cr 520.6nm, Cu 218.2nm, Pb 205.3nm and Zn 307.6nm. The limit of detection was 4.2ngga degree 1 for Cd, 1.1I14gga degree 1 for Cr, 0.5I14gga degree 1 for Cu, 1.3I14gga degree 1 for Pb and 8.6I14gga degree 1 for Zn for the maximum sample mass used. Under optimized conditions, the analyte and matrix were separated effectively in situ, and aqueous standards could be used for calibration.

Development of genetic tools and completion of the M. avium subsp. paratuberculosis genome sequencing project have expanded the opportunities for antigen discovery. In this study, we determined the seroreactivities of two proteins encoded at the 5' and 3' regions of the MAP1152-MAP1156 gene cluster. MAP1152 encodes a PPE protein, and MAP1156 encodes a diacylglycerol acyltransferase involved in triglyceride metabolism and classified in the uncharacterized protein family UPF0089. Recombinant MAP proteins were overproduced and purified from Escherichia coli as maltose-binding protein (MBP) fusions. Immunoblotting analysis indicated that both MAP1152 and MAP1156 displayed reactivity against sera of mice and rabbits immunized with live M. avium subsp. paratuberculosis cells and against samples from naturally infected cattle. In immunoblot assays, MAP1156 yielded a stronger positive signal than MAP1152 against sera from cattle with JD. An enzyme-linked immunosorbent assay for the recombinant proteins was developed and used to test preclassified positive and negative serum samples from naturally infected and noninfected cattle. Samples, with one exception, displayed no seroreactivity against the MBP-LacZ fusion protein (P > 0.05), the negative-control antigen. MAP1152 displayed seroreactivity against all positive sera but no seroreactivity to the negative sera (P < 0.01). MAP1156 displayed stronger and more variable reactivity than MAP1152, but significant differences were observed between noninfected and infected cattle (P < 0.05). Otherwise, degrees of reactivity followed the same trend as the positive reference antigen. In conclusion, both proteins are immunogenic in mice and rabbits, and M. avium subsp. paratuberculosis-infected cattle mount a humoral response to both MAP1152 and MAP1156 cross-reactive epitopes. These findings have potential applications to diagnostics, vaccine production, and elucidation of the immunopathogenesis of JD.

Residential addresses were geocoded and linked to classified-aerial imagery to calculate tree-canopy cover in 50, 100, and 200 m buffers around each home in our sample (n@=5696). Detailed data on maternal characteristics and additional neighborhood variables were obtained from birth certificates and tax records. We found that a 10% increase in tree-canopy cover within 50 m of a house reduced the number of small for gestational age births by 1.42 per 1000 births (95% CI - 0.11-2.72). Results suggest that the natural environment may affect pregnancy outcomes and should be evaluated in future research.

The compounds were dissolved in aqueous Tween 80, and 20aaI14L of the test solution was placed at three positions on the leaf, and a needle was used to puncture the leaf through each drop; the results were evaluated after 48aah. In contrast to previous studies, we found the carboxylic acid group is essential for phytotoxicity. Nicotinic acid was considerably less phytotoxic than picolinic acid and conversion of picolinic acid to the amide or N-oxide decreased phytotoxicity. Increasing the alkyl chain length at the 5-position on picolinic acid from two up to five carbons atoms increased phytotoxicity.

Consequently, before use in field sampling, methods should be validated. The three objectives of this study were, first, to determine whether a channel catfish Ictalurus punctatus (Rafinesque) fingerling classified as positive for Gram-negative Edwardsiella ictaluri infection according to bacterial culture before freezing was also classified as positive after freezing, second, to determine how direct culture from the kidney (DIRECT), culture of homogenate (HOMOG) and standard PCR (PCR) agree with bacterial culture in terms of classifying fish as positive or negative and third, to estimate diagnostic sensitivity (dSe) and diagnostic specificity (dSp) for DIRECT, HOMOG and PCR. In fresh and frozen fish, as bacterial concentration decreased, the ability of each assay to detect positive fish also decreased, especially when there were <104 colony-forming units per gram (CFUg-1) tissue. HOMOG proved to be the most reliable at correctly classifying catfish, whether they were subclinically or clinically infected. PCR assay was the least reliable. Overall, values for this study population for dSe were 0.66, 0.92 and 0.43, and for dSp were 0.86, 0.91 and 0.95, for DIRECT, HOMOG and PCR respectively.

This aquatic pathogen has a worldwide distribution and is highly infectious to both warm and cold water fish. A modified live F. columnare vaccine was developed by repeated passage of a virulent strain on increasing concentrations of rifampicin that resulted in attenuation. Here we report vaccination/challenge trials to evaluate efficacy and safety. In separate laboratory trials, immersion vaccination of channel catfish (Ictalurus punctatus) fry between 10 to 48 days post hatch (DPH) with experimental vaccine or licensed product resulted in relative percent survival (RPS) between 57-94% following challenge. Similarly, a vaccination/challenge trial using largemouth bass (Micropterus salmoides) fry at 10 DPH was performed using various doses of licensed product under laboratory conditions. Results demonstrated safety of the vaccine and significant protection following challenge with RPS values between 74-94%, depending on vaccine dose. Together, these trials demonstrate the vaccine administered to early life-stage channel catfish and largemouth bass is safe and reduces mortality following challenge with F. columnare. Flavobacterium columnare is an aquatic bacterium causing columnaris disease in fish. Laboratory efficacy of a modified live F. columnare vaccine was evaluated. The vaccine was delivered to young fish (7-48 days post hatch) by immersion. The modified live F. columnare vaccine protected largemouth bass and channel catfish.

However, this is the first time that immature seed from (Cicuta maculata) has been implicated in livestock poisoning. Nine mature Hereford cows from a herd of 81 died in northwestern Utah after ingesting immature seed heads of water hemlock (Cicuta maculata) in late summer. No obvious signs of poisoning were reported as all nine were found dead near the banks of the stream where water hemlock was found. Upon discovery of the dead cows, the remaining 72 cows were immediately removed from the pasture and no further losses occurred. Field necropsy of 3 of the dead cows and follow-up serology and histopathological examination of selected tissues did not identify any bacterial or viral causes. History of ingestion of large quantities of water hemlock seed, the acute nature of the deaths, chemical comparison of seed with toxic tubers and follow-up mouse bioassay testing supported the diagnosis of water hemlock poisoning. Seed heads collected from the neighboring pasture upstream and across the fence from the poisoned cattle and tubers collected from grazed plants were chemically analyzed and found to contain cicutoxin, and high levels of two cicutol-like derivatives (cicutol-#1 and #2) as well as other unidentified polyacetylene compounds. Seeds and tubers from suspected plants were semi-quantified and compared to archive samples of highly toxic tubers used in previous experiments. The immature hemlock seed contained less cicutoxin (0.01 times), but 9.5 and 22.5 times more cicutol-#1 and cicutol-#2 respectively, compared to the archive sample. Tubers from the grazed plants contained 4.6 times more cicutoxin and 9.8 and 18.8 times more cicutol-#1aaand cicutol-#2 respectively, compared to the archive sample. Mouse bioassays with water extracts of immature seed and tubers from grazed plants demonstrated both were highly toxic and of greater toxicity when compared to archived sample.

The soils store as much as 17,600 kg of NO (sub 3) (super -1) N ha (super -1) within the upper 208 cm. This paper provides an explanation. These Holocene soils receive NO (sub 3) (super -1) N from mineralization of organic matter and other NO (sub 3) (super -1) N sources including snowmelt. The NO (sub 3) (super -1) is delivered to soils in the first part of snowmelt in run-off from the higher surfaces. The last part of the melt and the run-off, when sufficient, serve to move the NO (sub 3) (super -1) out of the root zone. Winter fat (Krascheninnikovia lanata), the most valuable winter grazing plant in the Great Basin, is the common plant on NO (sub 3) (super -1) N rich soils. The soils are loamy or sandy and lack horizons restricting water penetration or biological denitrification zones. Hence, some NO (sub 3) (super -1) is free to leach deeply past plant roots. Playas, wet floodplains, deeply gullied inset fans and well-developed soils accumulate little NO (sub 3) (super -1) except where the latter soils are capped by desert pavements and rarely, if ever become saturated with water. Soils with argillic or petrocalcic horizons or duripans on summits of alluvial fan remnants loose NO (sub 3) (super -1) through denitrification, or incorporate it in plants, commonly accumulating less than 50 kg of NO (sub 3) (super -1) N ha (super -1) . These soils however do accumulate salt as shown by their shadscale saltbush Atriplex confertifolia, bud sagebrush Picrothamnus desertorum, and four-wing saltbush Atriplex conescens shrub cover.

Mass flux techniques are being used to calculate epsilon sub(g). Flux-based estimates of epsilon sub(g) depend partly on how PAR absorption by plants is modeled as a function of leaf area index (LAI). We used CO sub(2) flux measurements from three native grasslands in the Great Plains of USA to determine how varying the value of the radiation extinction coefficient (k) that is used to calculate PARa from LAI affected variability in estimates of epsilon sub(g) for each week. The slope of linear GPP-PARa regression, an index of epsilon sub(g), differed significantly among the 18 site-years of data, indicating that inter-annual differences in epsilon sub(g) contributed to the overall variability in epsilon sub(g) values. GPP-PARa slopes differed among years and sites regardless of whether k was assigned a fixed value or varied as an exponential function of LAI. Permitting k to change with LAI reduced overall variability in epsilon sub(g), reduced the slope of a negative linear regression between seasonal means of epsilon sub(g) and potential evapotranspiration (PET), and clarified the contribution of inter-annual differences in precipitation to variation in epsilon sub(g). Our results imply that greater attention be given to defining dynamics of the k coefficient for ecosystems with low LAI and that PET and precipitation be used to constrain the epsilon sub(g) values employed in light-use efficiency algorithms to calculate GPP for Great Plains grasslands.

In such species, mate selection is presumably based on direct benefits associated with sperm quantity or quality and/or indirect benefits relating to the viability or mating probability of the progeny. Across animal taxa in general, male age has received considerable attention as a potential indicator of these fitness benefits, and the importance of male age in affecting female choice and fitness has been investigated in various insect species with highly variable results. The present study examined whether females of the Mediterranean fruit fly (medfly), Ceratitis capitata (Wied.), a lek-forming species, discriminate among potential mates on the basis of male age and whether this selectivity results in fitness benefits to the females. Both young (10days old) and old (40days old) females were offered males from two groups differing in age by 10, 20, or 30days. Young females mated randomly when the age difference between the younger and older males was 10days but mated preferentially with the younger males when the age difference was 20 or 30days. Old females did not discriminate among males of different ages. Although young females showed mate selectivity, we found no differences in fecundity, fertility, or larval viability between young females mated to 10 versus 40day old males.

Standard titration is the typical field method for measuring dissolved CO2 in aquaculture systems. However, titrimetric determination of dissolved CO2 in marine water aquaculture systems is unsuitable because of the high dissolved solids, silicates, and other dissolved minerals that interfere with the determination. Other methods used to measure dissolved carbon dioxide in an aquaculture water included use of a wetted CO2 probe analyzer, standard nomographic methods, and calculation by direct measurements of the water's pH, temperature, and alkalinity. The determination of dissolved CO2 in saltwater based on partial pressure measurements and non-dispersive infra-red (NDIR) techniques with a CO2 gas analyzer are widely employed for oceanic surveys of surface ocean CO2 flux and are similar to the techniques employed with the head space unit (HSU) in this study. Dissolved carbon dioxide (DC) determination with the HSU using a infra-red gas analyzer (IRGA) was compared with titrimetric, nomographic, calculated, and probe measurements of CO2 in freshwater and in saltwater with a salinity ranging from 5.0 to 30ppt, and a CO2 range from 8 to 50mg/L. Differences in CO2 measurements between duplicate HSUs (0.1-0.2mg/L) were not statistically significant different. The coefficient of variation for the HSU readings averaged 1.85% which was better than the CO2 probe (4.09%) and that for the titrimetric method (5.84%). In all low, medium and high salinity level trials HSU precision was good, averaging 3.39%. Differences existed between comparison testing of the CO2 probe and HSU measurements with the CO2 probe readings, on average, providing DC estimates that were higher than HSU estimates. Differences between HSU and titration based estimates of DC increased with salinity and reached a maximum at 32.2ppt. These differences were statistically significant (P <0.05) at all salinity levels greater than 0.3ppt. Results indicated reliable replicated results from the head space unit with varying salinity and dissolved carbon dioxide concentrations.

Minimum estimated germ-line transformation frequencies were approximately 13-21% per fertile G sub(0) individual, similar to previously reported frequencies using single vector-helper plasmids. Two vector constructs were tested with potential importance to transgenic strain development for mexfly biological control. The first allows post-integration stabilization of a transposon-vector by deletion of a terminal sequence necessary for mobilization. The complete pB[L1-EGFP-L2-DsRed-R1] vector was integrated into the Chiapas wild type strain with subsequent deletion of the L2-DsRed-R1 sub-vector carrying the piggyBac 3' terminal sequence. Quality control tests for three of the stabilization vector lines (previous to stabilization) assessed viability at all life stages, fertility, adult flight ability, and adult male sexual competitiveness. All three transgenic lines were less fit compared to the wild strain by approximately 5-10% in most tests, however, there was no significant difference in sexual competitiveness which is the major prerequisite for optimal strain release. The second vector, pB[XL-EGFP, Asss2-tub-DsRed.T3], has the DsRed.T3 fluorescent protein reporter gene regulated by the A. suspensa Asss2-tubulin promoter, that resulted in testis and sperm-specific DsRed fluorescence in transgenic male mexflies. Fluorescent sperm bundles were unambiguously observed in the spermathecae of non-transgenic females mated to transgenic males. One transgenic line apparently had a male-specific Y-chromosome insertion, having potential use for sexing by fluorescent-embryo sorting. All transgenic lines expressed easily detectable and stable fluorescence in adults allowing their identification after trapping in the field.

Agricultural experiments are typically highly complex, with many types of variables often collected at a wide range of temporal and spatial scales. Furthermore, research in the developing world is often conducted on-farm where simple and conventional experimental designs are often unsuitable. Recently, a variant of stochastic dominance called stochastic efficiency with respect to a function (SERF) has been developed and used to analyse long-term experimental data. Unlike traditional stochastic dominance approaches, SERF uses the concept of certainty equivalents (CEs) to rank a set of risk-efficient alternatives instead of finding a subset of dominated alternatives. This study evaluates the efficacy of the SERF methodology for analysing conventional and conservation tillage systems using 14 years (1990-2003) of economic budget data collected from 36 experimental plots at the Iowa State University Northeast Research Station near Nashua, IA, USA. Specifically, the SERF approach is used to examine which of two different tillage systems (chisel plough and no-till) on continuous corn (Zea mays) and corn/soyabean (Glycine max) rotation cropping systems are the most risk-efficient in terms of maximizing economic profitability (gross margin and net return) by crop across a range of risk aversion preferences. In addition to the SERF analysis, we also conduct an economic analysis of the tillage system alternatives using mean-standard deviation and coefficient of variation for ranking purposes. Decision criteria analysis of the economic measures alone provided somewhat contradictive and non-conclusive rankings, e.g. examination of the decision criteria results for gross margin and net return showed that different tillage system alternatives were the highest ranked depending on the criterion and the cropping system (e.g. individual or rotation). SERF analysis results for the tillage systems were also dependent on the cropping system (individual, rotation or whole-farm combined) and economic outcome of interest (gross margin or net return) but only marginally on the level of risk aversion. For the individual cropping systems (continuous corn, rotation corn and rotation soyabean), the no-till tillage and rotation soyabean system was the most preferred and the chisel plough tillage and continuous corn system the least preferred across the entire range of risk aversion for both gross margin and net return. The no-till tillage system was preferred to the chisel plough tillage system when ranking within the continuous corn and the corn-soyabean rotation cropping systems for both gross margin and net return. Finally, when analysing the tillage system alternatives on a whole-farm basis (i.e. combined continuous corn and corn-soybean rotation), the no-till tillage system was clearly preferred to the chisel plough tillage system for both gross margin and net return. This study indicates that the SERF method appears to be a useful and easily understood tool to assist farm managers, experimental researchers and, potentially, policy makers and advisers on problems involving agricultural risk.

In mammals, cells of the innate immune system detect pathogenic molecular structures using pattern recognition receptors (PRRs). TLR9 functions as a PRR that recognizes CpG motifs in bacterial and viral DNA and requires adaptor molecules MyD88 and TRAF6 for signal transduction. Here we report full-length cDNA isolation, structural characterization and tissue mRNA expression analysis of the common carp (cc) TLR9, MyD88 and TRAF6 gene orthologs. The ccTLR9 open-reading frame (ORF) is predicted to encode a 1064-amino acid (aa) protein. We found that MyD88 and TRAF6 genes are duplicated in common carp. This is the first report of TRAF6 duplication in a vertebrate genome and stronger evidence in support of MyD88 duplication is provided. The ccMyD88a and b ORFs are predicted to encode 288-aa and 284-aa peptides, respectively. They share 91% aa sequence identity between paralogs. The ccTRAF6a and b ORFs are both predicted to encode 543-aa peptides sharing 95% aa sequence identity between paralogs. The ccTLR9 gene is contained in a single large exon. The ccMyD88a and ccMyD88b coding sequences span five exons. The TRAF6b gene spans six exons. PCR amplification to obtain the entire coding sequence of ccTRAF6a gene was not successful. The 2104-bp fragment amplified covers the 3' end of the gene and it contains a partial sequence of one exon and three complete exons. The predicated protein domains of the ccTLR9, ccMyD88 and ccTRAF6 are conserved and resemble orthologs from other vertebrates. Real-time quantitative PCR assays of the ccTLR9, MyD88a and b, and TRAF6a and b gene transcripts in healthy common carp indicated that mRNA expression varied between tissues. Differential expression of duplicate copies were found for ccMyD88 and ccTRAF6 in white and red muscle tissues, suggesting that paralogs may have evolved and attained a new function. The genomic information we describe in this paper provides evidence of sequence and structural conservation of immune response genes in common carp.

Under California regulations, minimizing emissions is essential to maintain the practical use of soil fumigants, and more stringent regulations are likely in the future. The phase-out of methyl bromide as a broad-spectrum soil fumigant has created formidable challenges. Most alternatives registered today are regulated as volatile organic compounds because of their toxicity and mobile nature. We review research on methods for minimizing emissions from soil fumigation, including the effectiveness of their emission reductions, impacts on pest control and cost. Low-permeability plastic mulches are highly effective but are generally affordable only in high-value cash crops such as strawberry. Crops with low profit margins such as stone-fruit orchards may require lower-cost methods such as water treatment or target-area fumigation.

Effectiveness can be improved by placing more filter strip where the runoff load is greater and less where the load is smaller. A modeling analysis was conducted of the relationship between pollutant trapping efficiency and the ratio of filter strip area to upslope contributing area, i.e., buffer area ratio.The results were used to produce an aid for designing filter strips having consistent effectiveness along field margins where runoff load is nonuniform. Simulations using the process-based Vegetative Filter Strip Model show that sediment and water trapping efficiencies of a filter strip increase nonlinearly as the buffer area ratio gets larger. Site characteristics, including slope, soil texture, and upslope soil cover management practices, help to define this relationship more accurately. Using the Vegetative Filter Strip Model simulation results, a graphical design aid was developed for estimating the buffer area ratio required to achieve specific trapping efficiencies for different pollutants under a broad range of agricultural site conditions. A single graph was produced showing simulation results for seven scenarios as a family of lines that divide the full range of possible relationships between trapping efficiency and buffer area ratio and into fairly even increments. Simple rules guide the selection of one line that best describes a given field situation by considering slope, soil texture, and field cover management practices. Relationships for sediment-bound and dissolved pollutants are interpreted from the Vegetative Filter Strip Model results for sediment and water. The design aid is easy to use, accounts for several major variables that determine filter strip performance, and is based on a validated, process-based, mathematical model. The use of this design aid will enable a more precise fit between filter size and runoff load where runoff from agricultural fields is nonuniform.

The soil conditioning index (SCI) is a relatively simple model used by the USDA-Natural Resources Conservation Service to predict qualitative changes in soil organic matter. Our objective was to develop a quantitative relationship between soil organic C derived from published field studies in the southeastern USA and SCI scores predicted from matching management conditions. We found that soil organic C sequestration (at 20 plus or minus 5cm depth) could be reliably related to SCI across a diversity of studies in the region using the regression slope: 1.65Mg C ha super(-1) SCI super(-1) [which translated into a rate of 0.25 plus or minus 0.04Mg C ha super(-1)yr super(ȡ 2; 1) SCI super(-1) (mean plus or minus standard error of 31 slope estimates)]. The calibration of soil organic C on SCI scores will allow SCI to become a quantitative tool for natural resource professionals to predict soil organic C sequestration for farmers wanting to adopt conservation practices.

During the last 2yr of the 9-yr experiment, shoot biomass was affected by canopy management with the burn (2,730kgha super(-1)) and mow (3,421kgha super(-1)) treatments containing less than no management (4,655kgha super(-1)). Burn treatment biomass contained 1,189kgha super(-1) and 25kgha super(-1) of C and N, mow contained 1,433kgha super(-1) and 33kgha super(-1) of C and N, while no management contained 2,014kgha super(-1) and 39kgha super(-1) of C and N, respectively. Soil C accumulation was independent of grass species composition. Soil C accumulation rates, which increased in strong linear fashion (r super(2) of 0.89 to 0.92) after initial grass establishment, were 387kg C ha super(-1)yr super(ȡ 2; 1), 503kg C ha super(-1)yr super(ȡ 2; 1), and 711kg C ha super(-1)yr super(ȡ 2; 1) for burn, mow, and no management treatments, respectively. Thus, grassland management methods used after conversion of cropland to grassland have important effects on grass biomass and soil C accumulation.

The effects of tillage, crop rotation, and cultural practice were evaluated on dryland crop biomass (stems + leaves) yield, surface residue, and soil organic C (SOC) and total N (STN) at the 0-20cm depth in a Williams loam (fine-loamy, mixed, superactive, frigid, Typic Argiustolls) from 2004 to 2007 in eastern Montana, USA. Treatments were two tillage practices [no-tillage (NT) and conventional tillage (CT)], four crop rotations [continuous spring wheat (CW), spring wheat-pea (Pisum sativum L.) (W-P), spring wheat-barley (Hordeum vulgaris L.) hay-pea (W-B-P), and spring wheat-barley hay-corn (Zea mays L.)-pea (W-B-C-P)], and two cultural practices [regular (conventional seed rates and plant spacing, conventional planting date, broadcast N fertilization, and reduced stubble height) and ecological (variable seed rates and plant spacing, delayed planting, banded N fertilization, and increased stubble height)]. Crop biomass and N content were 4 to 44% greater in W-B-C-P than in CW in 2004 and 2005 and greater in ecological than in regular cultural practice in CT. Soil surface residue amount and C and N contents were greater in NT than in CT, greater in CW, W-P, and W-B-C-P than in W-B-P, and greater in 2006 and 2007 than in 2004 and 2005. The SOC and STN concentrations at 0-5cm were 4 to 6% greater in CW than in W-P or W-B-P in NT and CT from 2005 and 2007. In 2007, SOC content at 10-20cm was greater in W-P and W-B-P than in W-B-C-P in CT but STN was greater in W-B-P and W-B-C-P than in CW in NT. From 2004 to 2007, SOC and STN concentrations varied at 0-5cm but increased at 5-20cm. Diversified crop rotation and delayed planting with higher seed rates and banded N fertilization increased the amount of crop biomass returned to the soil and surface residue C and N. Although no-tillage increased surface residue C and N, continuous nonlegume cropping increased soil C and N levels at the surface layer compared with other crop rotations. Continued return of crop residue from 2004 to 2007 may increase soil C and N levels but long-term studies are needed to better evaluate the effect of management practices on soil C and N levels under dryland cropping systems in the northern Great Plains.

Sap from trees is extracted to make a local drink; once they are tapped the individual usually dies. Plants are also illegally harvested for the nursery trade and destroyed by poachers hunting the endemic and threatened Hispaniolan parrot. We used 7 DNA microsatellite markers to assist land managers in developing conservation strategies for this palm. We sampled 4 populations along the known distribution range of this species (3 populations from the mainland and 1 from the small island of Isla Beata), for a total sample of n = 104. We found strong evidence for genetic drift, inbreeding, and moderate gene flow (i.e., all populations had at least 4 loci that were not in Hardy-Weinberg equilibrium, at least 9 loci pairs were in linkage disequilibrium, the pairwise F sub(ST) values ranged from 0.069 to 0.266, and had positive F sub(IS) values). Data supported an isolation-by-distance model, and cluster analyses based on genetic distances resolved 2 groups that match a north-south split. The population from Isla Beata had the lowest levels of genetic diversity and was the only one in which we found pairs of individuals with identical shared multilocus genotypes.

In central Louisiana, USA, two fertilization levels--No (NF) or Yes (F-36kg/ha N and 40kg/ha P) in combination with three vegetation treatments--Check, four prescribed fires (PF), or multi-year vegetation control by herbicidal and mechanical means (IVM) were applied to container-grown longleaf pine plantings in a grass savanna. After 10years, P concentration in longleaf pine foliage was less on NF plots than F plots, but fertilization did not significantly affect tree stature. Survival was greater on NF plots than F plots, and so, NF plots were more productive (NF--63m super(3)/ha and F--45m super(3)/ha). Pine trees on IVM plots (37dm super(3)/tree) were significantly larger than on Check and PF plots, which averaged 17dm super(3)/tree. Survival was better on IVM plots (88%) than PF plots (78%), which was better than Checks (58%). Consequently, IVM plots were most productive (99m super(3)/ha), followed by PF plots (44m super(3)/ha), and lastly Checks (28m super(3)/ha). PF plots had greater grass cover (38%) than Check and IVM plots, which averaged 5%, whereas PF and IVM plots had less understory arborescent cover (an average of 25%) than Checks (91%). A wildfire in March 2007 reduced pine survival by 22, 14, and 1 percentage points on IVM, Check, and PF plots, respectively. Seven months later, longleaf pine production had decreased to 92m super(3)/ha on IVM plots while increasing to 55m super(3)/ha on PF plots and 30m super(3)/ha on Checks. Overall, the wildfire rejuvenated the herbaceous plant community. Grass cover on Check and IVM plots averaged 20% while grass cover on PF plots was 36%. Forb cover increased on all treatments from 2% before the wildfire to 13% seven months after the wildfire. Understory arborescent cover decreased on Checks to 62% but increased slightly on PF and IVM plots and averaged 30%.

Such expert-based assessments can be difficult to document and apply consistently over time and space. We describe and reflect on the process of developing a computer-based decision support application from expert judgments for assessing aquatic and riparian conditions over the 100,000km super(2) managed by the US federal government under the Northwest Forest Plan. The decision support system helped structure and document the assessment process and provided consistency and transparency to the evaluation methodology. However, many decisions and trade-offs were required in the expert engagement and model-building processes. Knowledge elicitation in an interactive group had a number of benefits over nominal group or Delphi processes, but efficient knowledge capture required considerable planning and expertise in the subject matter and modeling process. Communicating model results for validation was problematic and only effectively accomplished via in-person workshops. The choice to use different expert groups for each biophysical province provided more opportunities for participation and promoted greater ownership in the assessment, but it also led to increased variation among the resulting model structures. We propose three possible approaches for better managing the consistency of assessment models when multiple expert groups are involved.

The fatty acids (short-chain fatty acids [SCFA]) were effective only when protonated and at sufficient concentrations. The conjugate bases were not effective at the concentrations evaluated. Predictions from an inhibition model (50% inhibitory concentration [IC50]) based on quantitative structure-activity relationships were congruent with inactivation data.

It produces the antibiotic 2,4-diacetylphloroglucinol and aggressively colonizes the roots of cereal crops. In this study, we analyzed the genome of Q8r1-96 and identified a type III protein secretion system (T3SS) gene cluster that has overall organization similar to that of the T3SS gene cluster of the plant pathogen Pseudomonas syringae. We also screened a collection of 30 closely related P. fluorescens strains and detected the T3SS genes in all but one of them. The Q8r1-96 genome contained ropAA and ropM type III effector genes, which are orthologs of the P. syringae effector genes hopAA1-1 and hopM1, as well as a novel type III effector gene designated ropB. These type III effector genes encoded proteins that were secreted in culture and injected into plant cells by both P. syringae and Q8r1-96 T3SSs. The Q8r1-96 T3SS was expressed in the rhizosphere, but mutants lacking a functional T3SS were not altered in their rhizosphere competence. The Q8r1-96 type III effectors RopAA, RopB, and RopM were capable of suppressing the hypersensitive response and production of reactive oxygen species, two plant immune responses.

It has been suggested that several phytopathogens aid in the persistence and proliferation of the human enteropathogens in the phyllosphere. In this work, we examined the influence of virulence mechanisms of Dickeya dadantii 3937, a broad-host-range phytopathogen, on the proliferation of the human pathogen E. coli O157:H7 EDL933 (EDL933) on postharvest lettuce by coinoculation of EDL933 with D. dadantii 3937 derivatives that have mutations in virulence-related genes. A type II secretion system (T2SS)-deficient mutant of D. dadantii 3937, A1919 ( Delta outC), lost the capability to promote the multiplication of EDL933, whereas Ech159 ( Delta rpoS), a stress-responsive sigma factor RpoS-deficient mutant, increased EDL933 proliferation on lettuce leaves. A spectrophotometric enzyme activity assay revealed that A1919 ( Delta outC) was completely deficient in the secretion of pectate lyases (Pels), which play a major role in plant tissue maceration. In contrast to A1919 ( Delta outC), Ech159 ( Delta rpoS) showed more than 2-fold-greater Pel activity than the wild-type D. dadantii 3937. Increased expression of pelD (encodes an endo-pectate lyase) was observed in Ech159 ( Delta rpoS) in planta. These results suggest that the pectinolytic activity of D. dadantii 3937 is the dominant determinant of enhanced EDL933 proliferation on the lettuce leaves. In addition, RpoS, the general stress response sigma factor involved in cell survival in suboptimal conditions, plays a role in EDL933 proliferation by controlling the production of pectate lyases in D. dadantii 3937.

Four cases were studied: 24-h pre-hydrolysis+48-h SSF (SSSF 24), 12-h pre-hydrolysis+60-h SSF (SSSF 12), 72-h SSF, and 48-h hydrolysis+24-h fermentation (SHF). The ethanol concentration, yield, and productivity of SSSF 24 were higher than those of the other operations. A model of SSF was used to simulate the data for four components in SSF. The analysis of the reaction rates of cellobiose, glucose, cell, and ethanol using the model and the parameters from the experiments showed that there was a transition point of the rate-controlling step at which the cell growth control in the initial 2h was changed to the cellobiose reaction control in later period during ethanol production of SSF from the mixture.

Crantz is an oilseed crop touted as being suitable for production in the arid southwestern USA. However, because any significant development of the crop has been limited to cooler, rain-fed climate-areas, information and guidance for managing irrigated-camelina are lacking. This study measured the crop water use of a November-through-April camelina crop in Arizona using frequent measurements of soil water contents. The crop was grown under surface irrigation using five treatment levels of soil water depletion. The seed yields of treatments averaged 1,142kgha super(-1) (8.0% seed moisture) and were generally comparable with camelina yields reported in other parts of the USA. Varying total irrigation water amounts to treatments (295-330mm) did not significantly affect yield, whereas total crop evapotranspiration (ET sub(c)) was increased for the most frequently irrigated treatment. However, total ET sub(c) for the camelina treatments (332-371mm) was markedly less than that typically needed by grain and vegetable crops (600-655mm), which are commonly grown during the same timeframe in Arizona. The camelina water-use data were used to develop crop coefficients based on days past planting, growing degree days, and canopy spectral reflectance. The crop coefficient curves, along with information presented on camelina soil water depletion and root zone water extraction characteristics will provide camelina growers in arid regions with practical tools for managing irrigations.

Field borders, fences, and vegetated strips that interrupt soil fluxes lead to the creation of topographic discontinuities or lynchets. When tillage tools that preferentially throw soil to one side are used repeatedly to move soil in one direction, rather than alternating with each pass, they create berms at the receiving side of the tilled domain and a "dead furrow" or channel at the contributing side. However, even tillage implements that are symmetrical in throwing soil equally in both lateral directions on flat surfaces may throw some soil beyond the implement width and so contribute to soil berms formation just beyond the tilled zone that can affect water flow paths. We developed a two-dimensional Tillage Erosion and Landscape Evolution Model that allows complex internal boundaries to be defined within the simulation domain. In this paper we develop and demonstrate techniques and tools to allow prediction of the formation of edge-of-field berms by defining alternative boundary conditions. The derivation and assumptions of the model are presented and then it is applied and compared to survey results from two field studies: one an experimental field in Coffeeville, Mississippi, where grass hedges were planted close to field elevation contours to evaluate their effectiveness as an erosion control measure and were monitored over a 16-year period; and the other a set of 0.1 ha plots located near Holly Springs, MS where the effect of edge-of-field berm formation on runoff partitioning was evaluated during an 8-year study. Results demonstrate the ability of the model to correctly reproduce the location and magnitude of soil loss and accumulation. At Coffeeville, erosion averaging over 20 cm in the downslope side of each grass hedge and deposition taking place near the slope ends led to the formation of lynchets up to 0.8 m high, and the average slope steepness in the cropped areas between hedges decreased from an average of 7.2% in 1993 to about 3.7% in 2009. In Holly Springs, repeated tillage conducted next to grass hedges planted along the hillslope bottoms led to the formation of berms with average height of 13 cm, which may significantly alter field-scale hydrological, erosion, and sediment transport processes.

Viruses isolated from broiler chicken offal washes (O) and poultry feces (F), designated Phi CP39O and Phi CP26F, respectively, produced clear plaques on host strains. Both bacteriophages had isometric heads of 57nm in diameter with 100-nm non-contractile tails characteristic of members of the family Siphoviridae in the order Caudovirales. The double-strand DNA genome of bacteriophage Phi CP39O was 38,753 base pairs (bp), while the Phi CP26F genome was 39,188bp, with an average GC content of 30.3%. Both viral genomes contained 62 potential open reading frames (ORFs) predicted to be encoded on one strand. Among the ORFs, 29 predicted proteins had no known similarity while others encoded putative bacteriophage capsid components such as a pre-neck/appendage, tail, tape measure and portal proteins. Other genes encoded a predicted DNA primase, single-strand DNA-binding protein, terminase, thymidylate synthase and a transcription factor. Potential lytic enzymes such as a fibronectin-binding autolysin, an amidase/hydrolase and a holin were encoded in the viral genomes. Several ORFs encoded proteins that gave BLASTP matches with proteins from Clostridium spp. and other Gram-positive bacterial and bacteriophage genomes as well as unknown putative Collinsella aerofaciens proteins. Proteomics analysis of the purified viruses resulted in the identification of the putative pre-neck/appendage protein and a minor structural protein encoded by large open reading frames. Variants of the portal protein were identified, and several mycobacteriophage gp6-like protein variants were detected in large amounts relative to other virion proteins. The predicted amino acid sequences of the pre-neck/appendage proteins had major differences in the central portion of the protein between the two phage gene products. Based on phylogenetic analysis of the large terminase protein, these phages are predicted to be pac-type, using a head-full DNA packaging strategy.

Fire-dependent ecosystems include some of the most threatened ecosystems in the world, and where fuels are allowed to accumulate, they can present significant threats to human life and property. Fuel reduction activities can be effective in reducing the risk of wildfire, but these practices need to be evaluated relative to their effect on biodiversity. We surveyed birds in an inland pitch pine-scrub oak barren, a fire-dependent plant community, in which fuel reduction had been carried out via thinning of canopy trees to reduce the risk of running crown fires. We hypothesized that thinning pitch pine forest would negatively affect the abundance of mature forest birds and positively affect the abundance of scrub-shrub birds. Our results confirmed these expectations: several mature forest bird species were less abundant in thinned pitch pine than unthinned pitch pine, although most of these species were also present in mixed deciduous forest, and therefore regionally well represented. In contrast, another group of bird species was scarce or absent from unthinned pitch pine and mixed deciduous forest, but present in thinned sites and scrub oak stands. These were scrub-shrub species that do not nest in mixed deciduous or pitch pine forest but depend on shrubland or savannah habitats that cover a arrow right 43% of the region. We conclude that fuel reduction by thinning canopy trees at this site provides habitat for high-priority scrub-shrub bird species at the cost of modest reductions in numbers of forest birds whose regional aggregate population is large.

Extensive tree dieback is a recurrent issue in many regions. Crown dieback of Fraxinus nigra Marsh. (black ash; brown ash) in the northeastern and north central United States is an example. F. nigra is a widely distributed hardwood that is often the dominant species in wetland forests from Manitoba to Newfoundland and West Virginia to Indiana. Widespread crown dieback of F. nigra has been noted in many regions, but there are few quantitative assessments of dieback extent or relationship to potential causes. Most F. nigra dieback episodes are not associated with specific disease or pest agents. Drought, excessive soil moisture, cohort senescense, and road influences, have all been suggested as potential contributing factors. Our objectives were to (1) quantify variable dieback across northern Minnesota, a region described as having extensive dieback, (2) determine the relationship between dieback and site moisture, (3) relate dieback to tree age/size distributions, and (4) assess whether dieback was related to road proximity. Given the increasing threat of Agrilus planipennis (emerald ash borer) in the region, it is important to know the current health status of F. nigra populations before widespread infestation occurs. Many stands in our study exhibited high incidences of crown dieback. However, the incidence of dieback was variable across the region. Spatial variability in dieback was associated with site wetland characteristics; more dieback occurred on jurisdictional wetlands and on sites with a higher wetness index and a deeper depth to a perching layer. Dieback was also positively correlated with mean stand diameter, and tree diameters were generally correlated with age, suggesting that stands with larger and older individuals experienced more dieback. Cohort senescence is a possible explanation for this trend. Finally, dieback occurred with higher frequency nearer to roads. The road influence could be related to hydrological alterations or perhaps toxicity from road deicing salt. The fact that dieback is more severe close to roads may contribute to a general perception that black ash dieback is more severe throughout the region than our study suggests. Collectively, our results indicate that the healthiest F. nigra stands in our study region are likely to be younger and located on relatively drier sites and farther from roads, compared to stands with significant crown dieback.

The status quo system (SQ) consisted of barley under-seeded with red clover followed by potato (2-year). The soil-conserving system (SC) featured an additional year of forage grass and reduced tillage (3-year, barley/timothy-timothy-potato). The soil-improving system (SI) added yearly compost amendments to the SC rotation, and the disease-suppressive system (DS) featured diverse crops with known disease-suppressive capability (3-year, mustard/rapeseed-sudangrass/rye-potato). Each system was also compared with a continuous potato control (PP) and evaluated under both irrigated and nonirrigated conditions. Data collected over three potato seasons following full rotation cycles demonstrated that all rotations reduced stem canker (10 to 50%) relative to PP. The SQ, SC, and DS systems reduced black scurf (18 to 58%) relative to PP; SI reduced scurf under nonirrigated but not irrigated conditions; and scurf was lower in DS than all other systems. The SQ, SC, and DS systems also reduced common scab (15 to 45%), and scab was lower in DS than all other systems. Irrigation increased black scurf and common scab but also resulted in higher yields for most rotations. SI produced the highest yields under nonirrigated conditions, and DS produced high yields and low disease under both irrigation regimes. Each cropping system resulted in distinctive changes in soil microbial community characteristics as represented by microbial populations, substrate utilization, and fatty acid methyl-ester (FAME) profiles. SI tended to increase soil moisture, microbial populations, and activity, as well result in higher proportions of monounsaturated FAMEs and the FAME biomarker for mycorrhizae (16:1 omega 6c) relative to most other rotations. DS resulted in moderate microbial populations and activity but higher substrate richness and diversity in substrate utilization profiles. DS also resulted in relatively higher proportions of FAME biomarkers for fungi (18:2 omega 6c), actinomycetes, and gram-positive bacteria than most other systems, whereas PP resulted in the lowest microbial populations and activity; substrate richness and diversity; proportions of monounsaturated and polyunsaturated FAME classes; and fungal, mycorrhizae, and actinomycete FAME biomarkers of all cropping systems. Overall, soil water, soil quality, and soilborne diseases were all important factors affecting productivity, and cropping systems addressing these constraints improved production. Cropping system approaches will need to balance these factors to achieve sustainable production and disease management.

Long-distance migration of P. ramorum has occurred via the nursery trade, and shipments of host plants are known to have crossed the U.S.-Canadian border. We investigated the genotypic diversity of P. ramorum in Canadian nurseries and compared the Canadian population with U.S. and European nursery isolates for evidence of migration among populations. All three of the P. ramorum clonal lineages were found in Canada but, unexpectedly, the most common was the NA2 lineage. The NA1 clonal lineage, which has been the most common lineage in U.S. nurseries, was found relatively infrequently in Canada, and these isolates may have been the result of migration from the United States to Canada. The EU1 lineage was observed almost every year and shared multilocus genotypes with isolates from Europe and the United States. Estimation of migration rates between Europe and North America indicated that migration was higher from Europe to North America than vice versa, and that unidirectional migration from Europe to North America was more likely than bidirectional migration.

The 13 most suppressive soil samples, which reduced zoospore production by 14 to 93% and disease severity on tubers by 6 to 21%, were used to isolate 279 organisms. Fourteen strains that reduce pink rot infections in preliminary tests were selected for further study. Six bacterial strains that reduced the severity of disease (P less than or equal to 0.05, Fischer's protected least significant difference) in subsequent tests were identified as Bacillus simplex (three strains), Pantoea agglomerans, Pseudomonas koreensis, and P. lini. Relative performance indices (RPIs) for biocontrol efficacy and for each of four kinetic parameters, including total colony-forming units (CFU sub(max)), biomass production values (DW sub(max)), cell production after 8 h (OD sub(8)), and time of recovery from oxygen depletion (DT) were calculated for each strain. Overall RPI sub(Eff,Kin) values for each strain then were calculated using strain RPI values for both efficacy (RPI sub(Eff)) and kinetics (RPI sub(Kin)). Strains with the highest RPI sub(Eff,Kin) possess the best biocontrol efficacy of the strains tested and liquid culture growth characteristics that suggest commercial development potential.

Using data from a long-term study of the Baltimore metropolitan region, we build on existing social scientific literature to examine a suite of theoretical factors that have been proposed to explain higher life satisfaction. We find support for many previous theoretical arguments in the literature. Importantly, however, our findings reveal that these results are strikingly scale dependent. For individuals, higher incomes contribute to higher levels of satisfaction, yet social capital does not. For neighborhoods, more social capital strongly increases satisfaction, but higher incomes do not; and access to a clean natural environment always contributes to higher satisfaction, regardless of the scale of analysis. Given these findings, we conclude with the observation that future research must carefully match the "scale" of life satisfaction measurements with the explanatory variables used.

The kinetics of humic acids sorption onto two different fractions of zeolite was evaluated and Freundlich isotherm was applied for finer fraction (below 0.1 mm). Freundlich constant was 0.002 mg.g super(-1) which indicates low affinity of humic acids towards the inorganic material in diluted solutions. The amount of sorbed humic acids slightly decreased the affinity of sorbent for arsenate at pH 7. The sorption capacity for iAs(V) decreased from 10.97 mg.g super(-1) to 7.57 mg.g super(-1).

In this study, a rapid assay was developed to simultaneously compare isolates for their ability to form biofilms as pure cultures. A total of 10 strains were isolated from a dry-grind fuel ethanol plant that routinely doses with virginiamycin. These were identified by sequence analysis as six strains of Lactobacillus fermentum, two strains of L. johnsonii, and one strain each of L. mucosae and L. amylovorus. Isolates exhibited a range of susceptibility to virginiamycin in a planktonic assay, with MIC's (minimum inhibitory concentration) of 0.5-16 mu g/ml. Even though all strains were isolated from a mixed culture biofilm, they varied greatly in their ability to form biofilms as pure cultures. Surprisingly, growth as biofilms did not appear to provide resistance to virginiamycin, even if biofilms were grown for 144 h prior to antibiotic challenge.

This issue was analysed by plenty of studies and publications characterised by a general as well as detail character. Thus, we know quite enough about the demographic essence of these changes, however, the social, macro-economical and social consequences and other wider aspects have been rarely analysed in Slovakia, in the Czech Republic as well as in other Central European countries. There is a scarcity of research on wide public perception of population development. Moreover, we have not found any study about the perception of population development by local authorities and central governments in these countries. Our study tries to fill this gap. It represents a pilot research on how the Slovak local self-government authorities (mayors) perceive demographical changes. They have been asked if they understand population ageing, if they realize what factors influence it, what social consequences the demographical development brings, and if they have any population strategies and forecasts for their own municipalities. Since the spatial differentiation is very peculiar with regard to the demographic processes, we tried to select different answers of mayors by linking them with several delimited regional types of municipalities and settlements. In addition to this geographical view, we discuss the need for a comprehensive approach in this field linking together demographical, geographical and sociological methods.

However, despite several decades of continuous large-scale logging, few efforts have been sustained at a regional level for reforestation of resulting degraded lands. Reforestation efforts have been limited to small, local and independent initiatives, with no movement on a regional or national level. In the past decade, however, the Christian Fellowship Church (CFC), a religious group in the Western Solomon Islands, has initiated a regional reforestation program in its member communities--a movement that has accelerated quickly and successfully. We use interviews and open-ended discussions with villagers and village leaders to explore how CFC has undertaken an apparently effective, large-scale reforestation project where the government, corporate logging companies, or localized kin groups have not. Results from the interviews reveal a diverse gamut of drivers, incentives, investments, and expectations for reforestation. Although respect of the power of the leader of the CFC was the most commonly cited reason for enrolling in reforestation, promises of income and land were also important in the success and widespread participation in the program. However, as this paper reveals, the significant time investment on a community level and by individual households, the growing expectation of financial return, and the distribution of land among community members for forestry, all will likely lead to unforeseen tensions in land tenure and resource ownership. Still, this reforestation initiative is a rare example of reforestation on customary land in Solomon Islands and one of the first models of a long-term, grassroots, religion-inspired community forestry effort in the Pacific.

Most studies have used county data, understating both systematic and random variation. Comparison of systematic versus random intra-county variation is lacking. Few studies compare the various distributional forms that have been proposed. This study utilizes the extensive potential of government farm-level crop insurance data. Results show that systematic intra-county variation is surprisingly strong. A newly applied reverse lognormal distribution is preferred when county-wide variation is removed, but the normal distribution fits surprisingly well in the crop insurance relevant percentiles when county-wide variation is not removed.

Cadmium enters plants from the soil solution. It traverses the root through symplasmic or apoplasmic pathways before entering the xylem and being translocated to the shoot. Leaf Cd concentrations in excess of 5-10 mu g g super(-1) dry matter are toxic to most plants, and plants have evolved mechanisms to limit Cd translocation to the shoot. Cadmium movement through the root symplasm is thought to be restricted by the production of phytochelatins and the sequestration of Cd-chelates in vacuoles. Apoplasmic movement of Cd to the xylem can be restricted by the development of the exodermis, endodermis, and other extracellular barriers. Increasing rhizosphere Cd concentrations increase Cd accumulation in the plant, especially in the root. The presence of Cd in the rhizosphere inhibits root elongation and influences root anatomy. Cadmium concentrations are greater in the root apoplasm than in the root symplasm, and tissue Cd concentrations decrease from peripheral to inner root tissues. This article reviews current knowledge of the proteins involved in the transport of Cd across root cell membranes and its detoxification through sequestration in root vacuoles. It describes the development of apoplastic barriers to Cd movement to the xylem and highlights recent experiments indicating that their maturation is accelerated by high Cd concentrations in their immediate locality. It concludes that accelerated maturation of the endodermis in response to local Cd availability is of functional significance in protecting the shoot from excessive Cd loads.

We investigated Se in Opuntia ficus-indica using inductively coupled plasma mass spectrometry, microfocused x-ray fluorescence elemental and chemical mapping ( mu XRF), Se K-edge x-ray absorption near-edge structure (XANES) spectroscopy, and liquid chromatography-mass spectrometry (LC-MS). mu XRF showed Se concentrated inside small conic, vestigial leaves (cladode tips), the cladode vasculature, and the seed embryos. Se K-edge XANES demonstrated that approximately 96% of total Se in cladode, fruit juice, fruit pulp, and seed is carbon-Se-carbon (C-Se-C). Micro and bulk XANES analysis showed that cladode tips contained both selenate and C-Se-C forms. Inductively coupled plasma mass spectrometry quantification of Se in high-performance liquid chromatography fractions followed by LC-MS structural identification showed selenocystathionine-to-selenomethionine (SeMet) ratios of 75:25, 71:29, and 32:68, respectively in cladode, fruit, and seed. Enzymatic digestions and subsequent analysis confirmed that Se was mainly present in a "free" nonproteinaceous form inside cladode and fruit, while in the seed, Se was incorporated into proteins associated with lipids. mu XRF chemical mapping illuminated the specific location of Se reduction and assimilation from selenate accumulated in the cladode tips into the two LC-MS-identified C-Se-C forms before they were transported into the cladode mesophyll. We conclude that Opuntia is a secondary Se-accumulating plant whose fruit and cladode contain mostly free selenocystathionine and SeMet, while seeds contain mainly SeMet in protein. When eaten, the organic Se forms in Opuntia fruit, cladode, and seed may improve health, increase Se mineral nutrition, and help prevent multiple human cancers.

Secondary goals of this study were to determine the extent to which MVPA confounded the associations between diet and adiposity and whether associations between diet and adiposity would differ depending on reporting error. METHODS: An ethnically diverse urban sample of 342 children aged 9-10 years and 323 adolescents aged 17-18 years were recruited for this cross-sectional study. Body mass index (BMI) and waist circumference (WC) were measured in the school; dietary assessment included three 24-hour recalls via telephone in the evenings, and MVPA assessment included 5 days of accelerometry. Over (n = 68), under (n = 250), or plausible (n = 347) dietary intake reporters were identified with the Huang calculation method. Linear regression assessed the relationship between adiposity indicators (BMI z-score and WC) and components of the diet (energy intake, food groups, macronutrients) after controlling for reporting error, demographic variables, and MVPA. RESULTS: When dietary reporting error and potential confounders such as MVPA and demographic variables were controlled, energy intake (EI), vegetables, refined grains, total fat, total protein, and total carbohydrate were positively related to BMI z-score and WC and artificially sweetened beverages to WC. MVPA was a significant confounder. For BMI z-score, but not WC, relationships and strength of these relationships differed depending on dietary reporting error group (plausible, underreporter, overreporter). CONCLUSIONS: Among plausible reporters, as expected, EI, refined grains, and all macronutrients were positively related to adiposity; however, artificially sweetened beverages and vegetables, which are low-energy-dense foods, were also positively related to adiposity. Reporting error interfered with associations between diet and BMI z-score but not WC, suggesting WC is a more robust measure of adiposity in relation to diet.

We investigated whether fat and carbohydrate intake modified the association of FTO gene variation with BMI in two populations, including participants in the Genetics of Lipid Lowering Drugs and Diet Network (GOLDN) study (n = 1069) and in the Boston Puerto Rican Health (BPRHS) study (n = 1094). We assessed energy, nutrient intake, and PA using validated questionnaires. Genetic variability at the FTO locus was characterized by polymorphisms rs9939609 (in the GOLDN) and rs1121980 (in the GOLDN and BPRHS). We found significant interactions between PA and FTO on BMI in the GOLDN but not in the BPRHS. We found a significant interaction between SFA intake and FTO on BMI, which was stronger than that of total fat and was present in both populations (P-interaction = 0.007 in the GOLDN and P-interaction = 0.014 in BPRHS for categorical; and P-interaction = 0.028 in the GOLDN and P-interaction = 0.041 in BPRHS for continuous SFA). Thus, homozygous participants for the FTO-risk allele had a higher mean BMI than the other genotypes only when they had a high-SFA intake (above the population mean: 29.7 plus or minus 0.7 vs. 28.1 plus or minus 0.5 kg/m2; P = 0.037 in the GOLDN and 33.6. plus or minus 0.8 vs. 31.2 plus or minus 0.4 kg/m2; P = 0.006 in BPRHS). No associations with BMI were found at lower SFA intakes. We found no significant interactions with carbohydrate intake. In conclusion, SFA intake modulates the association between FTO and BMI in American populations.

Historically, standing dead tree C has been estimated as a function of live tree growing stock volume in the U.S.'s National Greenhouse Gas Inventory. Initiated in 1998, the USDA Forest Service's Forest Inventory and Analysis program (responsible for compiling the Nation's forest C estimates) began consistent nationwide sampling of standing dead trees, which may now supplant previous purely model-based approaches to standing dead biomass and C stock estimation. A substantial hurdle to estimating standing dead tree biomass and C attributes is that traditional estimation procedures are based on merchantability paradigms that may not reflect density reductions or structural loss due to decomposition common in standing dead trees. The goal of this study was to incorporate standing dead tree adjustments into the current estimation procedures and assess how biomass and C stocks change at multiple spatial scales. Results: Accounting for decay and structural loss in standing dead trees significantly decreased tree- and plot-level C stock estimates (and subsequent C stocks) by decay class and tree component. At a regional scale, incorporating adjustment factors decreased standing dead quaking aspen biomass estimates by almost 50 percent in the Lake States and Douglas-fir estimates by more than 36 percent in the Pacific Northwest. Conclusions: Substantial overestimates of standing dead tree biomass and C stocks occur when one does not account for density reductions or structural loss. Forest inventory estimation procedures that are descended from merchantability standards may need to be revised toward a more holistic approach to determining standing dead tree biomass and C attributes (i.e., attributes of tree biomass outside of sawlog portions). Incorporating density reductions and structural loss adjustments reduces uncertainty associated with standing dead tree biomass and C while improving consistency with field methods and documentation.

This study used six forest management experimental sites in five northern states of the US to investigate the effects of silvicultural treatments (light thinning, heavy thinning, and clearcutting) on forest floor and soil carbon pools. Results: No overall trend was found between forest floor carbon stocks in stands subjected to partial or complete harvest treatments. A few sites had larger stocks in control plots, although estimates were often highly variable. Forest floor carbon pools did show a trend of increasing values from southern to northern sites. Surface soil (0-5 cm) organic carbon content and concentration were similar between treated and untreated plots. Overall soil carbon (0-20 cm) pool size was not significantly different from control values in sites treated with partial or complete harvests. No geographic trends were evident for any of the soil properties examined. Conclusions: Results indicate that it is unlikely that mineral soil carbon stocks are adversely affected by typical management practices as applied in northern hardwood forests in the US; however, the findings suggest that the forest floor carbon pool may be susceptible to loss.

Previous analyses have shown that it is an exceptionally clonal serotype, which nonetheless generates considerable phenotypic heterogeneity. Due to its clonality, whole genome analysis is required to find genetic determinants that contribute to strain heterogeneity of Salmonella Enteritidis. Comparative whole genome mutational mapping of two PT13a strains that varied in the ability to contaminate eggs and to form biofilm was achieved using a high-density tiling platform with primers designed from a PT4 reference genome. Confirmatory Sanger sequencing was used on each putative SNP identified by mutational mapping to confirm its presence and location as compared to the reference sequence. High coverage pyrosequencing was used as a supporting technology to review results. Results: A total of 250 confirmed SNPs were detected that differentiated the PT13a strains. From these 250 SNPS, 247 were in the chromosome and 3 were in the large virulence plasmid. SNPs ranged from single base pair substitutions to a deletion of 215 bp. A total of 15 SNPs (3 in egg-contaminating PT13a 21046 and 12 in biofilm forming PT13a 21027) altered coding sequences of 16 genes. Pyrosequencing of the two PT13a subpopulations detected 8.9% fewer SNPs than were detected by high-density tiling. Deletions and ribosomal gene differences were classes of SNPs not efficiently detected by pyrosequencing. Conclusions: These results increase knowledge of evolutionary trends within Salmonella enterica that impact the safety of the food supply. Results may also facilitate designing 2 super(nd )generation vaccines, because gene targets were identified that differentiate subpopulations with variant phenotypes. High-throughput genome sequencing platforms should be assessed for the ability to detect classes of SNPs equivalently, because each platform has different advantages and limits of detection.

Ninety overweight and obese participants were randomly assigned to 1 of 3 treatment groups for 23 wk: 1) WP; 2) SP (each providing approximately 56 g/d of protein and 1670 kJ/d); or 3) an isoenergetic amount of CHO. Supplements were consumed as a beverage twice daily. Participants were provided no dietary advice and continued to consume their free-choice diets. Participants' body weight and composition data were obtained monthly. Dietary intake was determined by 24-h dietary recalls collected every 10 d. After 23 wk, body weight and composition did not differ between the groups consuming the SP and WP or between SP and CHO; however, body weight and fat mass of the group consuming the WP were lower by 1.8 kg (P < 0.006) and 2.3 kg (P < 0.005), respectively, than the group consuming CHO. Lean body mass did not differ among any of the groups. Waist circumference was smaller in the participants consuming WP than in the other groups (P < 0.05). Fasting ghrelin was lower in participants consuming WP compared with SP or CHO. Through yet-unknown mechanisms, different sources of dietary protein may differentially facilitate weight loss and affect body composition. Dietary recommendations, especially those that emphasize the role of dietary protein in facilitating weight change, should also address the demonstrated clinical potential of supplemental WP.

Chlorine dioxide is approved for use as an antimicrobial treatment during poultry processing. A study was designed to test if application of 50 ppm of ClO2 during defeathering could prevent the expected increase in Campylobacter numbers on carcasses. Three replications were conducted, each using carcasses from different Campylobacter-positive flocks. Carcasses were collected from the shackle line immediately before and after defeathering with and without ClO2 spray; all carcasses were subjected to a whole-carcass rinse. Rinsate was cultured for Campylobacter, Escherichia coli, and SALMONELLA: Carcasses sprayed with ClO2 during defeathering had significantly lower numbers of Campylobacter and E. coli than carcasses treated with the water spray control defeathering. The ClO2 defeathering treatment also resulted in a lower prevalence of Salmonella than did control defeathering. Antimicrobial resistance profiles of Campylobacter and Salmonella isolates collected from ClO2-treated carcasses were not different from those collected from control carcasses.

Specific players involved in triggering and maintaining inflammation (i.e. those regulating adipokine release and WAT macrophage recruitment, retention, or function) remain to be fully elaborated, and the degree to which moderate obesity promotes WAT inflammation remains to be clarified further. Therefore, we characterized adiposity and metabolic phenotypes in adult male C57BL/6J mice fed differing levels of dietary fat (10, 45, and 60% of energy) for 12 wk, concurrent with determinations of WAT inflammation markers and mRNA expression of leukocyte-derived integrins (CD11b, CD11c, CD11d) involved in macrophage extravasation and tissue macrophage homing/retention. As expected, a lard-based, very high-fat diet (60% energy) significantly increased adiposity and glucose intolerance compared with 10% fat-fed controls, coincident with higher retroperitoneal (RP) WAT transcript levels for proinflammatory factors and macrophage markers, including TNF alpha and CD68 mRNA, which were approximately 3- and approximately 15-fold of control levels, respectively (P 300-fold of controls in the 45 and 60% fat groups) (P < 0.0001) and this induction was WAT specific. Because we found that CD11d expression also increased in RP-WAT of Zucker obese rats and in the subcutaneous WAT of obese adult women, this appears to be a common feature of obesity. Observed correlations of WAT macrophage transcript marker abundances with body weight in lean to modestly obese mice raises an interesting possibility that the activities of at least some WAT macrophages are closely linked to the normal adipose remodeling that is a requisite for changes in WAT energy storage capacity.

This can be attributed to an increasing demand for poultry meat and egg products. However, a major problem facing the poultry industry is the large-scale accumulation of wastes including manure and litter which may pose disposal and pollution problems unless environmentally and economically sustainable management technologies are evolved. Most of the litter produced by the poultry industry is currently applied to agricultural land as a source of nutrients and soil amendment. However environmental pollution, resulting from nutrient and contaminant leaching can occur when poultry litter is applied under soil and climatic conditions that do not favour agronomic utilisation of the manure-borne nutrients. This review examines the composition of poultry litter in relation to nutrient content and environmental contaminants, its value as a nutrient source, soil amendment, animal feed and fuel source, and cost-effective innovative technologies for improving its value. Poultry litter provides a major source of nitrogen, phosphorus and trace elements for crop production and is effective in improving physical and biological fertility, indicating that land application remains as the main option for the utilisation of this valuable resource. The alternative use of poultry litter; as an animal feed and fuel source, is limited by contaminants, and high moisture content, respectively. The review proposes best management practices to mitigate environmental consequences associated with air and water quality parameters that are impacted by land application in order to maintain the continued productivity, profitability, and sustainability of the poultry industry.

AN - 815963718; 21055491 AB - Management of prairie dogs in the past has included poisoning, fumigants, barriers, and relocation. Because of the diverse attitudes related to prairie dog management, nonlethal methods that allow the existence of prairie dogs but help minimize damage related to population growth need to be developed. GonaConâ„¢ is an immunocontraceptive vaccine that elicits antibodies to native GnRH; this prevents the secretion of reproductive hormones necessary for sperm and oocyte production. Prairie dogs were vaccinated with 0.1, 0.2, or 0.4 mL of the GonaConâ„¢ emulsion intramuscularly in the upper thigh containing 100, 200, or 400 μg GnRH conjugate, respectively. Control animals were vaccinated with 0.4 mL saline emulsion in the upper thigh. Blood samples (≤1 mL) were taken from the femoral vein once pretreatment and at 1, 2, 3, 4, 6, and 15 months post-vaccination. Age (adult or juvenile) did not affect immune response to GonaConâ„¢. Antibody titers were higher in the 200 and 400 μL GonaConâ„¢ groups than in the 100 μL group, and there was no difference between the 200 and 400 μL GonaConâ„¢ groups. No adverse effects of GonaConâ„¢ were noted on weight or blood chemistry parameters during the study. GonaConâ„¢ will likely contracept prairie dogs for ≥1 year in the field using either 200 or 400 μg conjugate. GonaConâ„¢ could be incorporated into management plans to help maintain prairie dog populations while reducing habitat degradation due to overpopulation. Published by Elsevier Ltd.

It has enabled a deeper analysis of genomic diversity among bacteria belonging to the Mycobacterium avium complex (MAC). In addition, the expression of thousands of genes can be studied simultaneously in a single experiment. With the complete genome sequence of a bovine isolate of M. avium subspecies paratuberculosis, and the independent construction of DNA microarrays in our laboratories, transcriptomic studies for this veterinary pathogen are now possible. Furthermore, the bovine genome sequence project is completed and bovine arrays have been developed to examine host responses to infection with M. avium subsp. paratuberculosis. Collectively, genomic and transcriptomic data has yielded novel insights surrounding the genetic regulation and biology of Johne's disease.

As lands are converted to bioenergy crops, including corn and cellulosic grasses, focus has been on changes in soil carbon sequestration. Little attention has been paid to impacts of such land conversion on the activity of belowground communities. We hypothesized that in addition to affecting soil organic carbon (SOC), monoculture species establishments have appreciable effects on microbial community activity, as evidenced by N and C mineralization rates. We compared soil microbial response in soils under long-term corn (Zea mays L.) production to soils under 10-year old monocultures of four warm-season perennial grasses (switchgrass (Panicum virgatum L.), coastal bermudagrass [Cynodon dactylon (L) Pers.], sideoats grama [Bouteloua curtipendula (Michaux) Torrey] and buffalo grass [Bouteloua dactyloides (Nutt.) Columbus]). All assayed perennial systems had higher SOC and water extractable organic C (WEOC) than the annual corn system. However, of all the perennial grasses, switchgrass soils had the lowest SOC and WEOC values, and the lowest 28-day C and N mineralization rates. This study indicates that soil microbial activities under buffalograss stands are more active than those under sideoats grama, switchgrass, coastal bermudagrass, or corn.

NoV are associated with raw shellfish outbreaks, particularly oysters, which are thought to bioaccumulate NoV particles during the filter-feeding process. NoV outbreaks, however, have also been known to occur from other common-source food-borne vehicles, such as lettuce, frozen raspberries, and salad. In this study, we evaluated romaine lettuce as a potential vehicle for NoV transmission by testing the binding and distribution of NoV to the surface of romaine. Recombinant Norwalk virus-like particles (rNVLP) applied to the surface of romaine lettuce localized as large clusters primarily on the leaf veins. An extract of romaine lettuce leaves in phosphate-buffered saline (PBS) (romaine extract [RE]) bound rNVLP in a dose-dependent manner. RE did not bind rNVLP by histo-blood group antigens (HBGA), nor was RE competitive with rNVLP binding to porcine gastric mucin. These results suggested that non-HBGA molecules in RE bind rNVLP by a binding site(s) that is different from the defined binding pocket on the virion. Extracts of cilantro, iceberg lettuce, spinach, and celery also bound rNVLP.

Routine field calibration of water vapor analyzers has always been a challenging problem for those making long-term flux measurements at remote sites. Automated sampling of standard gases from compressed tanks, the method of choice for CO2 calibration, cannot be used for H2O. Calibrations are typically done manually with a dew point generator, and as a consequence are done less frequently, degrading the accuracy and utility of H2O flux data. To remedy this, we have designed, built and tested a field-portable mixing ratio generator, also including features that facilitate its use in water vapor isotope research. It consists of an aluminum cell, with a usable capacity of 80cm3, that is coupled to a Peltier heater/cooler and encased in insulation. The temperature of water in the cell is monitored with a thermocouple and a pressure transducer is used to measure the cell pressure. A data logger uses this information to compute the mixing ratio in the cell and control the polarity and duty cycle of the power input to the Peltier block in order to drive the system toward the desired mixing ratio and to maintain it. Incoming air enters through a bubbler and the exiting air is directed to the gas analyzer. A separate fitting mates to a syringe, allowing easy filling and draining of the cell. The cost of the components, exclusive of the data logger, is approximately 1100 USD. Power consumption is low, on the order of 10W, facilitating use at remote sites. As a consequence, the response time of the instrument is relatively slow, but could be substantially improved for situations where dynamic response is more important than power consumption. Testing has shown that the unit is accurate over a broad range of mixing ratios, able to compensate for changes in ambient pressure, and stable for long periods of time. In addition, it has been used to generate Rayleigh distillation plots, demonstrating its utility for routinely checking the performance of water vapor isotope lasers.

In contrast to previous reports, the current study modelled landscape scale effects of fuel treatments on fire spread and intensity, and used a probabilistic framework to quantify wildfire effects on carbon pools to account for stochastic wildfire occurrence. The study area was a 68 474 ha watershed located on the Fremont-Winema National Forest in southeastern Oregon, USA. Fuel reduction treatments were simulated on 10% of the watershed (19% of federal forestland). We simulated 30 000 wildfires with random ignition locations under both treated and untreated landscapes to estimate the change in burn probability by flame length class resulting from the treatments. Carbon loss functions were then calculated with the Forest Vegetation Simulator for each stand in the study area to quantify change in carbon as a function of flame length. We then calculated the expected change in carbon from a random ignition and wildfire as the sum of the product of the carbon loss and the burn probabilities by flame length class. The expected carbon difference between the non-treatment and treatment scenarios was then calculated to quantify the effect of fuel treatments. Overall, the results show that the carbon loss from implementing fuel reduction treatments exceeded the expected carbon benefit associated with lowered burn probabilities and reduced fire severity on the treated landscape. Thus, fuel management activities resulted in an expected net loss of carbon immediately after treatment. However, the findings represent a point in time estimate (wildfire immediately after treatments), and a temporal analysis with a probabilistic framework used here is needed to model carbon dynamics over the life cycle of the fuel treatments. Of particular importance is the long-term balance between emissions from the decay of dead trees killed by fire and carbon sequestration by forest regeneration following wildfire.

In this paper, we first present the policy motivation for examining continued producer adoption of water conserving irrigation production systems as a foundation for providing a sustainable future for western irrigated agriculture. Second, we summarize the historical transitions that help to define the adjustment path to increased sustainability for the sector. While western irrigated agriculture is on a path toward greater sustainability, evidence suggests that the sustainability goal has not been fully attained. Third, we develop a new conceptual framework for groundwater management that endogenizes both per acre applied water and an acreage-based technology adoption relationship within a normative, dynamic-optimization model for groundwater irrigated agriculture. The framework models producer adoption decisions under uncertainty while accounting for the influence of irrigation technology as a quasi-fixed input, i.e., the influence of asset fixity on producer adoption decisions. In this model, total crop production is based on consumptive use of irrigation water while the cost side is based on total applied water.

Plant species identity affects the oviposition behavior of O. insidiosus in that it prefers plants where newly hatched nymphs perform best, in the absence of prey. Choice tests were conducted in the laboratory to determine if the presence of a high-quality prey item (Lepidopteran eggs) affects oviposition choice in a monoculture and also how prey presence affects oviposition preference for plants of high (i.e., green bean, Phaseolus vulgaris) or low (soybean, Glycines max) suitability for O. insidiosus. O. insidiosus laid 56.4% more eggs on prey-free P. vulgaris than prey-free G. max. The presence of prey on P. vulgaris increased oviposition on those plants by 26.4% over that laid on prey-free P. vulgaris. When G. max with prey was presented alongside prey-free P. vulgaris, O. insidiosus still laid 55.4% more eggs on the latter. Prey availability affects oviposition on plants of equivalent quality, but plant suitability over-rides the importance of prey availability for this zoophytophagous insect. Phytophagy in young nymphs is important for their survival and we hypothesize that O. insidiosus females are better able to forecast plant quality than future prey populations as resources for their offspring.

Volatile compounds produced by A. flavus, as well as those present in the PDA controls and sterile cracked maize, were collected using solid-phase micro-extraction (SPME) and identified by gas chromatography/mass spectrometry. Results show that growth substrate had a major impact on the number and type of volatiles detected. Growth on sterile cracked maize produced many more volatiles than did potato dextrose agar. There were also differences observed in the type of volatiles produced between toxigenic and non-toxigenic isolates, as well as between isolates of the same toxigenic grouping.

These biofuels offer potential benefits as alternatives to fossil fuels, but mitigating any environmental risks posed by large-scale cultivation of bioenergy feedstock (biofeedstock) species poses new challenges: some proposed biofuel crops have become naturalized, and even invasive; the relative risks and benefits of growing monocultures versus polycultures of biofeedstock species require more thorough examination; and prompt development of a robust ecological risk assessment framework and careful screening are needed before these biofuel species are widely cultivated. Greater collaboration between agronomists developing crops for biofeedstock production and invasion biologists could substantially lower the risk of new plant invasions.

When lactic acid was combined with chicken odor, attraction was increased for Cx. quinquefasciatus compared to chicken odor alone but not for Cx. nigripalpus, Cx. tarsalis, and Ae. aegypti. Lactic acid combined with hand odor did not change attraction of Cx. tarsalis and Ae. aegypti but decreased attraction of Cx. nigripalpus and Cx. quinquefasciatus. The addition of lactic acid to CO2 increased attraction of Ae. aegypti and Cx. quinquefasciatus but reduced attraction of Cx. nigripalpus and Cx. tarsalis. Use of commercial lactic acid baits with CO2 resulted in a similar trend except for Cx. nigripalpus which showed no difference. A blend of lactic acid, acetone, and dimethyl disulfide was attractive to Ae. aegypti (63.4%) but elicited low responses by all Culex spp. (1.3-26.8%). Addition of the blend to CO2 increased attraction of Ae. aegypti and Cx. quinquefasciatus but reduced attraction of Cx. nigripalpus and Cx. tarsalis. The mixture of compounds plus CO2 was as attractive as a hand for Cx. quinquefasciatus, Cx. tarsalis, and Ae. aegypti.

Data from 284 pelicans captured or collected at loafing sites located near aquaculture ponds during 1998 to 2009 were analyzed. A sampling bias could suggest segregation of pelicans by sex or age on wintering grounds. Captured pelicans were strongly biased towards immature males (73%) and collected pelicans were male biased (38% Adult Male, 47% Immature Male). Although the underlying mechanisms are not understood, observed pelican use of loafing areas may be related to numerous, readily available prey at aquaculture facilities.

Seven species of phytophagous stink bugs were found on corn with the predominant species being Nezara viridula (L.) and Euschistus servus (Say). All developmental stages of these two pests were found, indicating they were developing on the corn crop. The remaining five species, Oebalus pugnax pugnax (F.), Euschistus quadrator (Rolston), Euschistus tristigmus (Say), Euschistus ictericus (L.), and Acrosternum hilare (Say), were found in relatively low numbers. Adult N. viridula were parasitized by the tachinid parasitoid Trichopoda pennipes (F.). There was a pronounced edge effect in distribution of stink bugs in corn. Population dynamics of N. viridula and E. servus were different on early and late-planted corn. Oviposition by females of both stink bug species occurred in mid-to-late-May and again mid-to-late-June in corn, regardless of planting date. In early planted fields, if stink bug females oviposited on corn in mid-July, the resulting nymphs did not survive to the adult stage in corn because ears were close to physiological maturity and leaves were senescing. Density of stink bug adults in early planted corn was relatively low throughout the growing season. In late-planted corn, females of both stink bug species consistently laid eggs in mid-to-late-July on corn with developing ears. This habitat favored continued nymph development, and the resulting adult population reached high levels. These results indicate that corn management practices play a key role in the ecology of stink bugs in corn agroecosystems and provide information for designing management strategies to suppress stink bugs in farmscapes with corn.

In this study, a rapid, cost-effective method was developed for identifying irrigation canal locations likely to have leaks and/or seepage. The method involves the use of a multispectral imager equipped with red, near infrared, and thermal sensors which is mounted on an aircraft and flown at low altitude to collect the images. A three-step process, image acquisition, image processing, and field reconnaissance, was developed for processing the imagery and identification of locations likely to have leaks. The method was evaluated in the Lower Rio Grande Valley of Texas, USA. Images were collected of 24 selected canal segments within 11 irrigation districts in this region. Evaluation of the imagery indicated that 140 sites had possible canal leakage problems (point leak and/or seepage). A field site evaluation form was developed and used to document the type and severity of the leaks at 28 of the sites. Twenty-six sites were confirmed to have leaks, representing a success rate of 93%. The methods used in this study should have widespread application for detecting leaks and seepage in irrigation canals.

It was detected in southern California in the late 1980s and in the San Joaquin Valley in 1999, where it transmits the bacterium Xylella fastidiosa to grapevines and other crops. The reproductive success of hybrid and pure line H. vitripennis from two geographically separated populations in California (Riverside (RIV) and Bakersfield (BAK)) was evaluated under identical conditions. The RIV and BAK populations had different preoviposition periods that persisted through the second generation of each lineage. From adult molt, the preoviposition period in both female generations was significantly shorter for RIV (F sub(0) = 28.2 days and F sub(1) = 62.3 days) than BAK females (F sub(0) = 46.1 days and F sub(1) = 170.4 days). After a 21-day mating period, F sub(0) and F sub(1) females deposited on average 391 (range, 21-967) and 196 (range, 0-755) eggs, respectively, without significant differences in fecundity among the F sub(0) and F sub(1) mating pair treatments. Egg accumulation rates among F sub(1) treatments showed that females in the RIV groups rapidly deposited their eggs within the first 120 days after adult molt while BAK females maintained a steady accumulation rate during their life. The performance of both hybrid lines was intermediate between the pure lineages. The F sub(0) mating pairs: [female]RIV x [male]RIV, [female]RIV x [male]BAK, [female]BAK x [male]RIV, and [female]BAK x [male]BAK produced on average 185, 94, 79, and 0 viable eggs, respectively, which suggested a delayed sexual maturity of BAK males and females. The proportion of viable eggs deposited decreased gradually, which suggests that females completely exhausted sperm reserves. From a management perspective, delayed reproductive maturity and polyandry are weak links in H. vitripennis' biology that may be exploited through mating disruption or insect sterilization strategies to reduce population growth and augment pressure by natural enemies.

AmyC and AmyD demonstrate pH optima of 5.5 and 6.0, respectively, nearly one unit higher than the Rhizopus AmyA glucoamylase enzyme. Optimal initial activities are at 60 and 50 degree C for AmyC and AmyD, respectively. Inactivation of both enzymes occurs at 50 degree C following 30min pre-incubation. The two enzymes demonstrate substantially slower catalytic rates toward soluble starch relative to AmyA. AmyC has similar k sub(cat) and K sub(m) for oligosaccharides to other Rhizopus and Aspergillus glucoamylases; however, the enzyme has a 2-fold lower K sub(m) super(maltose) . AmyD has a 3-fold higher K sub(m) and lower k sub(cat) for maltooligosaccharides than AmyC and other glucoamylases. AmyC (but not AmyD) exhibits substrate inhibition. K sub(i) for substrate inhibition decreases with increasing length of the oligosaccharides. Data from pre-steady-state binding of AmyC to maltose and maltotriose and pre-steady-state to steady-state catalytic turnover experiments of AmyC acting on maltotriose were used to interrogate models of substrate inhibition. In the preferred model, AmyC accumulates an enzyme-maltose-maltotriose dead-end complex in the steady state.

Replication and stability factors of pXF-RIV11 were identified and used to construct plasmids able to replicate in X. fastidiosa and Escherichia coli. Replication in X. fastidiosa required a 1.4-kbp region from pXF-RIV11 containing a replication initiation gene (trfA) and the adjacent origin of DNA replication (oriV). Constructs containing trfA and oriV from pVEIS01, a related IncP-1 plasmid of the earthworm symbiont Verminephrobacter eiseniae, also were competent for replication in X. fastidiosa. Constructs derived from pXF-RIV11 but not pVEIS01 replicated in Agrobacterium tumefaciens, Xanthomonas campestris, and Pseudomonas syringae. Although plasmids bearing replication elements from pXF-RIV11 or pVEIS01 could be maintained in X. fastidiosa under antibiotic selection, removal of selection resulted in plasmid extinction after 3 weekly passages. Addition of a toxin-antitoxin addiction system (pemI/pemK) from pXF-RIV11 improved plasmid stability such that >80 to 90% of X. fastidiosa cells retained plasmid after 5 weekly passages in the absence of antibiotic selection. Expression of PemK in E. coli was toxic for cell growth, but toxicity was nullified by coexpression of PemI antitoxin. Deletion of N-terminal sequences of PemK containing the conserved motif RGD abolished toxicity. In vitro assays revealed a direct interaction of PemI with PemK, suggesting that antitoxin activity of PemI is mediated by toxin sequestration.

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.

Debate over the efficacy of converting diverse native plant communities to managed monocultures prompted us to explore the extensive crop and ecological site productivity databases maintained by US Department of Agriculture-Natural Resources Conservation Service. We compared annual net primary productivity (ANPP) of diverse native plant communities to ANPP of alfalfa (Medicago sativa L.) in Nebraska, Kansas, and Oklahoma; to coastal bermudagrass (Cynodon dactylon [L.] Pers.) in northern and central Texas; and to buffelgrass (Pennisetum ciliare [L.] Link.) in extreme southern Texas. In only 21% of the 1,238 sites in Nebraska, Kansas, and Oklahoma did native communities produce more or equivalent ANPP compared with managed alfalfa or coastal bermudagrass. In contrast, southern Texas native communities had greater ANPP than did buffelgrass at 81% of the sites. Regression analyses based on these results suggested that managed switchgrass (Panicum virgatum L.) ANPP would consistently exceed native community ANPP. We identified the type of sites that could remain in diverse communities or be converted to diverse communities and have productivity as great as or greater than highly managed monocultures of alfalfa, coastal bermudagrass, or buffelgrass. However, because of the low ANPP on these sites, biomass production may not be the optimal use of such sites. These lands may be better suited to providing other ecosystem services.

Our objectives were to determine the effect of selected post-plant, preemergence herbicides on stand establishment and subsequent biomass yields of adapted upland switchgrass cultivars grown in three environments in the Central and Northern Great Plains. A separate experiment was conducted in eastern Nebraska to determine if there were any differences among switchgrass ecotypes for herbicide tolerance to the optimal herbicide combination. Herbicides applied immediately after planting were different concentrations of atrazine [Aatrex 4L registered ; 6-chloro-N-ethyl-N'-(1-met hylethyl)-1,3,5-triazine-2,4-diamine], quinclorac (Paramount registered ; 3,7-Dichloro-8-quinolinecarboxylic acid), atrazine+quinclorac, imazapic {Plateau registered ; 2-[4,5-dihydro-4-methyl-4-(1-methylethyl)-5-oxo-1H-imidazol-2-yl]- 5 -methyl-3-pyridinecarboxylic acid}, and quinclorac+imazapic. Herbicide efficacy was determined by measuring stand frequency of occurrence and biomass yield the year after establishment. The application of quinclorac plus atrazine resulted in acceptable stands and high biomass yields. Imazapic often reduced switchgrass stands in comparison to the nontreated control and is not recommended for switchgrass establishment. In the multi-state trials, the herbicide by cultivar interaction was not significant for stands or biomass yields, indicating that the effects of herbicides on switchgrass stands and biomass yields were consistent over the upland cultivars used in the trials. No differences were detected among switchgrass lowland and upland ecotypes for tolerance to atrazine and quinclorac. Quinclorac, which provides effective control of grassy weeds, and herbicides such as atrazine which provide good broadleaf weed control are an excellent herbicide combination for establishing switchgrass for biomass production in the Great Plains and the Midwest.

Biochar is being promoted as a soil amendment to enhance soil quality, it is also seen as a mechanism of long-term sequestration of carbon. Our experiments tested the hypothesis that biochar is inert in soil. However, we measured an increase in CO sub(2) production from soils after biochar amendment which increased with increasing rates of biochar. The d super(13)C signature of the CO sub(2) evolved in the first several days of the incubation was the same as the d super(13)C signature of the biochar, confirming that biochar contributed to the CO sub(2) flux. This effect diminished by day 6 of the incubation suggesting that most of the biochar C is slowly decomposing. Thus, aside from this short-term mineralization increasing soil C with young biochar may indeed be a long-term C storage mechanism.

Minimal attention has been given to the efficient exploitation of crop diversity and the synergistic and/or antagonistic relationships of crops in crop sequences. Objectives of our research were to determine if previous crop sequences have long-term benefits and/or drawbacks on spring wheat seed yield, seed N concentration, and seed precipitation-use efficiency in the semiarid northern Great Plains, USA. Research was conducted 6 km southwest of Mandan, ND using a 10 x 10 crop matrix technique as a research tool to evaluate multiple crop sequence effects on spring wheat (triticum aestivum L.) production in 2004 and 2005. Spring wheat production risks can be mitigated when second year crop residue was dry pea (Pisium sativum L.) averaged over all first year crop residues. When compared to spring wheat as second year crop residue in the dry year of 2004, dry pea as the second year residue crop resulted in a 30% spring wheat seed yield increase. Sustainable cropping systems need to use precipitation efficiently for crop production, especially during below average precipitation years like 2004. Precipitation use efficiency average over all treatments, during the below average precipitation year was 23% greater than the above average precipitation year of 2005. Diversifying crops in cropping systems improves production efficiencies and resilience of agricultural systems.

In regions containing a limited number of measurement sites per footprint, some of the observed difference between the retrievals and ground observations is attributable to spatial sampling error and not the intrinsic error of the satellite retrievals themselves. Here, a triple collocation (TC) approach is applied to footprint-scale soil moisture products acquired from passive microwave remote sensing, land surface modeling, and a single ground-based station with the goal of the estimating (and correcting for) spatial sampling error in footprint-scale soil moisture estimates derived from the ground station. Using these three soil moisture products, the TC approach is shown to estimate point-to-footprint soil moisture sampling errors to within 0.0059 m super(3) m super(-3) and enhance the ability to validate satellite footprint-scale soil moisture products using existing low-density ground networks.

Rhizoctonia solani AG-5 can be a significant component of this complex and is effectively suppressed via multiple functional mechanisms in response to Brassica juncea seed meal (SM) amendment. These mechanisms include those of both a biological and chemical nature. The effect of seed meal particle size on the operation of these mechanisms and the resulting capacity of B. juncea SM to suppress R. solani and other components of the pathogen complex that incites replant disease of apple was examined in this study. Emission of ally isothiocyanate (AITC) from B. juncea SM-amended soil was initiated earlier and reached higher maximal concentrations in soils amended with fine particle (<1mm dia) than coarse particle (2-4mm dia) size SM. This corresponded with the level of disease suppression obtained when R. solani AG-5 and SM at a rate of 0.3% (wt/wt) were introduced concurrently into soils and planted to apple; fine particle size but not coarse particle size B. juncea SM suppressed apple root infection. At the same rate, Pratylenchus penetrans and Pythium spp. were effectively controlled by B. juncea SM applications irrespective of SM particle size. AITC emission from B. juncea SM-amended soils was completed within 72h post amendment, even at an application rate as high as 1.0% (wt/wt). In both fine and coarse particle size B. juncea SM-amended soils, populations of resident Streptomyces spp. were elevated approximately five to ten-fold at 8weeks post-application relative to the non-treated control soil. When soil was infested with R. solani AG-5 subsequent to this 8week incubation period and planted to apple, B. juncea SM amendments effectively suppressed Rhizoctonia root rot irrespective of SM particle size. Relative R. solani AG-5 apple root infection as determined by culture-based methods and a qPCR method developed in these studies was consistently similar across experiments. These findings demonstrate that particle size will affect the efficacy of B. juncea SM soil amendment for the control of R. solani AG-5, but will do so only through effects on chemistry-and not biologically-based mechanisms of pathogen suppression.

However, because of the appearance of new genotypes (biotypes) in response to deployment of resistance, field collections of Hessian fly need to be evaluated on a regular basis to provide breeders and producers information on the efficacy of resistance (R) genes with respect to the genotype composition of Hessian fly in regional areas. We report here on the efficacy of 21 R genes in wheat to field collections of Hessian fly from the southeastern United States. Results documented that of the 21 R genes evaluated only five would provide effective protection of wheat from Hessian fly in the southeastern United States. These genes were H12, H18, H24, H25, and H26. Although not all of the 33 identified R genes were evaluated in the current study, these results indicate that identified genetic resistance to protect wheat from Hessian attack in the southeastern United States is a limited resource. Historically, R genes for Hessian fly resistance in wheat have been deployed as single gene releases. Although this strategy has been successful in the past, we recommend that in the future deployment of combinations of highly effective previously undeployed genes, such as H24 and H26, be considered. Our study also highlights the need to identify new and effective sources of resistance in wheat to Hessian fly if genetic resistance is to continue as a viable option for protection of wheat in the southeastern United States.

Nutrients removed in these feedstocks have soil fertility implication and affect feedstock quality. The study objectives were to quantify nutrient concentrations and potential removal as a function of cutting height, plant organ, and physiological stage. Plant samples were collected in 10-cm increments at seven diverse geographic locations at two maturities and analyzed for multiple elements. At grain harvest, nutrient concentration averaged 5.5gNkg super(-1), 0.5gPkg super(-1), and 6.2gKkg super(-1) in cobs, 7.5gNkg super(-1), 1.2gPkg super(-1), and 8.7gKkg super(-1) in the above-ear stover fraction, and 6.4gNkg super(-1), 1.0gPkg super(-1), and 10.7gKkg super(-1) in the below-ear stover fraction (stover fractions exclude cobs). The average collective cost to replace N, P, and K was 11.66 Mg super(-1) for cobs , 17.59Mg super(-1) for above-ear stover, and 18.11 Mg super(-1) for below - ear stover . If 3 Mg super(-1) ha 1 of above - ear stover fraction plus 1 Mg of cobs are harvested , an average N , P , and K replacement cost was estimated at 64ha super(-1). Collecting cobs or above-ear stover fraction may provide a higher quality feedstock while removing fewer nutrients compared to whole stover removal. This information will enable producers to balance soil fertility by adjusting fertilizer rates and to sustain soil quality by predicting C removal for different harvest scenarios. It also provides elemental information to the bioenergy industry.

Physiological variability among isolates of the fungus is unknown. One way to measure physiologic variability is to analyze growth on different carbon sources. The carbon source utilization profiles of 18 F. virguliforme isolates were examined using the Biolog FF 96-well microplate, which contains 95 different carbon sources. The utilization of dextrin, d-mannitol, maltotriose, d-lactic acid methyl ester, N-acetyl-d-galactosamine, salicin, d-trehalose, and l-alanine differed significantly among isolates (P = 0.05). Carbon sources were grouped into 3 clusters based on their ability to promote growth of F. virguliforme, after calculating Euclidean distances among them. About 12% of the carbon sources promoted a high amount of mycelial growth, 39% promoted a medium amount of growth, and 49% promoted a low amount of mycelial growth; the latter was not significantly different from the water blank control. A hierarchical tree diagram was produced for the 18 isolates based on their carbon source utilization profiles using Ward's hierarchical analysis method. Two main clusters of isolates were formed. One cluster represented greater average mycelial growth on all of the carbon sources than the other cluster. In this study, variability in carbon source utilization among F. virguliforme isolates was evident, but the results were not associated with geographic origin of the isolates, year collected, or published data on aggressiveness. Additional research is needed to determine if these carbon utilization profiles are associated with other biological characteristics, like spore germination, propagule formation, and saprophytic competitiveness.Original Abstract: Fusarium virguliforme est l'agent responsable du syndrome de la mort subite de la feve de soya. La variabilite physiologique des isolats de ce champignon est inconnue. Une facon d'en mesurer la variabilite physiologique consiste a en analyser la croissance sur differentes sources de carbone. Les profils d'utilisation de sources de carbone de 18 isolats de F. virguliforme ont ete examines a l'aide du systeme de microplaque Biolog FF a 96 puits, qui contient 95 sources differentes de carbone. L'utilisation de la dextrine, du d-mannitol, du maltotriose, du methylester d'acide d-lactique, de la N-acetyl-d-galactosamine, de la salicine, du d-trehalose et de la l-alanine differait significativement en fonction des isolats (P = 0,05). Les sources de carbone ont ete groupees en 3 grappes selon leur capacite a promouvoir la croissance de F. virguliforme, apres avoir calcule les distances Euclidiennes qui les separent. Environ 12 % des sources de carbone permettaient la croissance d'une grande quantite de mycelium, 39 % permettaient la croissance d'une quantite moyenne et 49 % permettaient une croissance d'une faible quantite de mycelium, cette derniere n'etant pas significativement differente de l'eau utilisee comme controle. Un arbre hierarchique a ete produit pour les 18 isolats en fonction de leur profil d'utilisation de sources de carbone, a l'aide de la methode de Ward. Deux grappes principales d'isolats ont ete formees. Une grappe representait les isolats dont la croissance moyenne de mycelium sur toutes les sources de carbone etait plus elevee que l'autre. Dans cette etude, la variabilite d'utilisation des sources de carbone par les isolats de F. virguliforme etait evidente, mais les resultats n'etaient pas associes a l'origine geographique des isolats, a l'annee de recolte ou aux donnees publiees sur leur agressivite. Des recherches supplementaires sont requises pour determiner si ces profils d'utilisation du carbone sont associes a d'autres caracteristique biologiques comme la germination des spores, la formation de propagules ou la competitivite saprophyte.

Watson) growth in a future climate with increased pest activity requires an understanding of the natural variability of quantitative resistance to disease. Foliar and bark secondary metabolites from different lodgepole pine provenances (populations) were quantified and correlated with severity of foliar diseases caused by Lophodermella spp. (Lophodermella concolor (Dearn.) Darker or Lophodermella montivaga Petre.) or Elytroderma deformans (Wier) Darker and bark diseases caused by Elytroderma or Endocronartium harknessii (J.P. Moore) Y. Hiratsuka. Greater foliar concentrations of lignin, tannins, and some phenolics were associated with increased resistance to single or multiple foliar pathogens. Bark secondary metabolites levels were generally unassociated with resistance to bark diseases. Provenances appearing to originate in ecosystems where lodgepole pine are not the dominant species generally were more susceptible to foliar diseases and had less foliar defense-associated compounds than trees from areas where pines were the dominant species, yet clear trends proved to be elusive. Regardless, pine provenances with greater foliar levels of identified defense-associated compounds should be preferred seed sources for replanting forests in areas in which foliar disease is expected to be increasingly prevalent.Original Abstract: Il faut connaitre la variabilite naturelle de la resistance quantitative aux maladies pour maximiser la croissance du pin tordu latifolie (Pinus contorta Douglas ex Louden var. latifolia Engelm. ex S.

Genetic modifications (GMO) to soybean have become inevitable on two fronts, both quality and yield will need to improve to meet increasing global demand. To ensure the safety of the crop for consumers it is important to determine the natural variation in seed protein constituents as well as any unintended changes that may occur in the GMO as a result of genetic modification. Understanding the natural variation of seed proteins in wild and cultivated soybeans that have been used in conventional soybean breeding programs is critical for determining unintended protein expression in GMO soybeans. In recent years, proteomic technologies have been used as an effective analytical tool for examining modifications of protein profiles. We have standardized and applied these technologies to determine and quantify the spectrum of proteins present in soybean seed. We used two-dimensional polyacrylamide gel electrophoresis (2D-PAGE), matrix-assisted laser desorption/ionization time of flight mass spectrometry (MALDI-TOF-MS), and liquid chromatography mass spectrometry (LC-MS) for the separation, quantification, and identification of different classes of soybean seed proteins. We have observed significant variations in different classes of proteins, including storage, allergen and anti-nutritional protein profiles, between non-GMO cultivated and wild soybean varieties. This information is useful for scientists and regulatory agencies to determine whether the unintended expression of proteins found in transgenic soybean is within the range of natural variation.

Here we examine the role of current and projected increases in carbon dioxide concentration [CO sub(2)], on soybean growth and seed yield with and without competition from Canada thistle (Cirsium arvense, a common perennial weed in soybean farming systems), over a 3-year period using no-tillage (i.e., no physical cultivation for weed removal) practices. Weed control was implemented by applying herbicide (glyphosate) as a pre-emergent treatment at the beginning of each growing season. Under a weed-free condition, round-up ready soybean demonstrated a significant response of seed yield and total above-ground biomass to elevated [CO sub(2)], but no synergistic effect of no-till over time on the response of biomass or yield to [CO sub(2)] was observed. Average above-ground weight of Canada thistle was significantly greater at elevated [CO sub(2)] for 2008 and 2009, and establishment of thistle increased as a function of [CO sub(2)] over time even with pre-emergent applications of glyphosate. Although the presence of Canada thistle reduced seed yield and biomass of soybean for both CO sub(2) treatments from 2007 to 2009, the reduction was higher for the elevated [CO sub(2)] treatment, and a significant [CO sub(2)] x Canada thistle interaction was observed for these parameters. Overall, these are the first data to indicate that perennial weeds associated with no-tillage practices could be a greater impediment to crop yields and harder to control chemically in response to rising levels of atmospheric carbon dioxide.

E. Smith); beet armyworm, Spodoptera exigua (Huebner); and cabbage looper, Trichoplusia ni (Huebner); was evaluated in the Lower Rio Grande Valley of Texas during 2004-2008. When noctuids were abundant, leaves or fruit were significantly less damaged and fewer live larvae were found on Bollgard II cotton compared with non-Bt cotton throughout the growing season. With few to moderate Lepidoptera, cotton with either of the two Bt traits had similar damage. One insecticide application to cotton with Bollgard, Bollgard II, WideStrike, or non-Bt traits resulted in significantly fewer bollworm and beet armyworm larvae and less damage on fruiting structures compared to nontreated cotton. Beet armyworm larval survival and damage to leaves on non-Bt cotton were 3.6-fold greater than on Bollgard II or WideStrike cotton and 1.5-fold greater than on cotton varieties with the Bollgard trait.

Mean water contents ranged from 0.013 m (super 3) m (super -3) near the surface at Victoria Valley to 0.33 m (super 3) m (super -3) near the ice-cemented layer at Granite Harbour. The coastal sites have greater soil water contents than the McMurdo Dry Valley and Mount Fleming sites, and moisture contents increase with depth in the active layer. The Wright Valley site receives very little infiltration from snowmelt, with none in most years. All other sites, except Mount Fleming, received between one and four wetting events per summer, and infiltrated water moved to greater depths. The Scott Base and Granite Harbour sites are on sloping ground and receive a subsurface flow of water along the ice-cemented permafrost. Our findings indicate that water contents are low with very little recharge, are greatly influenced by the local microclimate and topography, and show no significant increasing or decreasing trend over 10 years of monitoring.

The content of linamarin was higher in terminal trifoliate leaves (435.5ppm) than in primary leaves (142.1ppm) of Henderson bush lima beans. However, linamarin concentrations were reversed at the second trophic level showing higher concentrations in spider mites feeding on primary leaves (429.8ppm) than those feeding on terminal trifoliate leaves (298.2ppm). Concentrations of linamarin in the predatory mites were 18.4 and 71.9ppm when feeding on spider mites grown on primary and terminal leaves, respectively. The concentration of lotaustralin in primary lima bean leaves was 103.12ppm, and in spider mites feeding on these leaves was 175.0ppm. Lotaustralin was absent in lima bean terminal trifoliate leaves and in mites feeding on these leaves. Fecundity of spider mites feeding on lima bean leaves (primary or trifoliate) was not significantly different from mites feeding on red bean, Phaseolus vulgaris L., primary leaves. However, the progeny sex ratio (in females per male) of spider mites feeding on lima bean leaves was significantly lower than progeny of spider mites feeding on red bean leaves (control). Fecundity and progeny sex ratio of P. persimilis were both significantly affected by the concentration of linamarin present in the prey. Changes in concentration of linamarin in living tissue across the three trophic levels are discussed.

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 sediments 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 2008, 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.

AN - 851466083; 14037447 AB - A box aerial-release system has been developed for the mass release of the arundo wasp, Tetramesa romana Walker, a biological control agent of giant reed, Arundo donax L., an invasive weed of waterways and riparian areas in the southwestern U.S. and Mexico. Because A. donax infests lengthy stretches of remote areas inaccessible by vehicle, an aerial release system may be the best way to disseminate biological control agents. The release system involves a paper box that can be easily loaded with chilled, immobile insects. The box opens upon contact with blades installed on a chute in the floor of an airplane. Preliminary tests in the field demonstrated the effectiveness of this system. All boxes recovered after test releases were successfully opened by the release chutes. Post-release emergence rates of insects were great and insect mortality rates were low, especially at moderate ambient temperatures (20-25 degree C). The box aerial-release system proves to be an appropriate method for release, especially at the early stages of an inundative biological control program for A. donax.

The objective of this work was to examine various cage shapes and mesh types for their filtration effects on air speed, spray droplet size, and spray volume. Reductions in wind speed and droplet size seen inside the cages were measured by placing cages in a low-speed wind tunnel at air speeds of 0.5m/sec, 1m/sec, 2m/sec, and 4m/sec and cage face orientations (relative to the air stream) of 0 degree , 10 degree , 22.5 degree , and 45 degree . Reduction in spray volume inside a select number of cages was also evaluated under similar conditions. Generally, greater air speed reductions were seen at lower external air speeds with overall reductions ranging from 30% to 88%, depending on cage type and tunnel air speed. Cages constructed with screens of lower porosities and smaller cylindrical-shaped cages tended to provide greater resistance to air flow and spray volume. Overall, spray droplet size inside the cages was minimally reduced by 0-10%. There was a 32-100% reduction in concentration of the spray volume applied relative to that recovered inside the bioassay cages, depending on the cage geometry and screening material used. In general, concentration reductions were greatest at lower air speeds and for cages with lower porosity screens. As a result of this work, field researchers involved in assessing the efficacy of vector control applications will have a better understanding of the air speed and spray volume entering insect bioassay cages, relative to the amount applied, resulting in better recommended application techniques and dosage levels.

Native ungulate biomass density averaged 5282 kg km-2 over the study and was dominated by elephant (Loxodonta africana), impala (Aepyceros melampus) and dik-dik (Madoqua kirkii). Biomass density of domestic cattle (Bos taurus) averaged 2280 kg km-2 during the study. Responses of native ungulates to severe drought were variable. Impala densities were similar to or greater than densities for similar habitat in protected areas, and varied from 12 to 16 km-2 during and following the drought to 24-29 km-2 following above-average rainfall. Dik-dik densities were also greater than densities reported for protected areas and were surprisingly stable throughout the study despite the wide annual fluctuations in rainfall. Elephant migrated out of the region during drought but were present at high densities (2.9-5.2 km-2) during wet seasons, consistent with telemetry studies emphasizing the importance of Acacia bushland habitat on commercial rangelands for the migratory portion of the Laikipia-Samburu elephant population. Results show that substantial densities of native browsing and mixed-feeding ungulates can occur on rangeland managed for commercial beef production and suggest that the capacity for ungulates to move over large spatial scales (>100 km2) and to shift distributions in response to locally variable thunderstorms may be important for sustaining these populations.

MAT-specific SNP primers were developed for polymerase chain reaction (PCR) and the two forms were differentiated by distinct PCR products: PttMAT1-1 (1, 143 bp) and PttMAT1-2 (1, 421 bp) for NF MAT1-1 and MAT1-2 isolates; PtmMAT1-1 (194 bp) and PtmMAT1-2 (939 bp) for SF MAT1-1 and MAT1-2 isolates, respectively. Specificity was validated using 37 NF and 17 SF isolates collected from different geographic regions. Both MAT1-1 and MAT1-2 SNP primers retained respective specificity when used in duplex PCR. No cross-reactions were observed with DNA from P. graminea, P. triticirepentis, or other ascomycetes, or barley. Single or mixed infections of the two different forms were also differentiated. This study provides the first evidence that the limited SNPs at the MAT locus are sufficient for distinguishing closely related heterothallic ascomycetes at subspecies levels, thus allowing pathogenicity and mating type characteristics of the fungus to be determined simultaneously. Methods presented will facilitate pathogen detection, disease management, and epidemiological studies.

In a series of experiments, multiple objectives were addressed to determine the (i) longevity of detached soybean leaves, (ii) reproductive capacity of uredinia on leaves inoculated and/or incubated on the abaxial versus adaxial side of the leaf, (iii) reproductive capacity of uredinia and urediniospore germination when spores were harvested at regular intervals or all at once, and (iv) effect of temperature and relative humidity (RH) on urediniospore germination. A detached-leaf assay using agar medium amended with 6-benzylaminopurine performed better in retarding leaf chlorosis than filter paper alone among five soybean genotypes. Among the three susceptible genotypes tested, detached leaves of cv. Williams 82 had the lowest level of leaf chlorosis and often allowed for the greatest urediniospore production and germination rate. Temperature and RH played significant roles in survival of urediniospore as measured by germination rates. Viable urediniospores were harvested from infected soybean leaves maintained at room temperature (23 to 24 degree C at 55 to 60% RH) for up to 18 days, whereas freshly harvested urediniospores that were desiccated for 12 h before being placed in vials and maintained at room temperature remained viable for up to 30 days. Urediniospore hydration was the major factor for the dormancy reversion; thermal shock with hydration and no thermal shock with hydration treatments had consistently similar urediniospore germination rates. In the RH experiment, urediniospores harvested from inoculated leaf pieces maintained at 85% RH had the highest germination rates compared with higher and lower RH. Improvement in P. pachyrhizi cultural techniques and understanding of urediniospore survival will enhance our knowledge of the pathogen biology, host-plant relationship, and conditions that favor the infection, reproduction, and survival of the pathogen.

Although none of the SDS fusaria have been shown to produce perithecia in nature, a heterothallic sexual cycle has been demonstrated for F. tucumaniae via laboratory crosses. Herein we report on the discovery of perithecia of F. tucumaniae on soybean in Argentina. Ascospores derived from these perithecia gave rise to colonies that produced sporodochial conidia diagnostic of F. tucumaniae. Sporodochial conidia were longer and narrower than those produced by the other SDS fusaria; these conidia also possessed a diagnostic acuate apical cell and a distinctly foot-shaped basal cell. Sixteen strains derived from single ascospores subjected to a validated multilocus genotyping assay (MLGT) for SDS species determination, together with 16 conidial isolates from two sites where teleomorphs were collected, independently confirmed the morphological identification as F. tucumaniae. This study represents the first authentic report of sexual reproduction by a soybean SDS pathogen in nature.

These same rotations were also assessed with and without the addition of a fall cover crop of no-tilled winter rye (except for barley/clover, for which underseeded ryegrass was substituted for clover) over a 4-year period. Canola and rapeseed rotations consistently reduced the severity of Rhizoctonia canker, black scurf, and common scab (18 to 38% reduction), and canola rotations resulted in higher tuber yields than continuous potato or barley/clover (6.8 to 8.2% higher). Addition of the winter rye cover crop further reduced black scurf and common scab (average 12.5 and 7.2% reduction, respectively) across all rotations. The combined effect of a canola or rapeseed rotation and winter rye cover crop reduced disease severity by 35 to 41% for black scurf and 20 to 33% for common scab relative to continuous potato with no cover crop. Verticillium wilt became a prominent disease problem only after four full rotation cycles, with high disease levels in all plots; however, incidence was lowest in barley rotations. Barley/clover and rapeseed rotations resulted in the highest soil bacterial populations and microbial activity, and all rotations had distinct effects on soil microbial community characteristics. Addition of a cover crop also resulted in increases in bacterial populations and microbial activity and had significant effects on soil microbial characteristics, in addition to slightly improving tuber yield (4% increase). Thus, in addition to positive effects in reducing erosion and improving soil quality, effective crop rotations in conjunction with planting cover crops can provide improved control of soilborne diseases. However, this study also demonstrated limitations with 2-year rotations in general, because all rotations resulted in increasing levels of common scab and Verticillium wilt over time.

As these resistance genes from cultivated oat, Avena sativa, and the wild hexaploid animated oat, A. sterilis, were deployed in oat cultivars, corresponding virulence in the U.S. crown rust population increased rapidly, such that the effective lifespan of a resistant cultivar in the United States is now 5 years or less. Introgression of resistance from diploid and tetraploid Avena spp. into hexaploid oat has been difficult due to the difference in ploidy levels and the lack of pairing of homeologous chromosomes between species. The wild tetraploid slender oat, A. barbata, has been a source of powdery mildew and stem rust resistance in cultivated oat but has largely been unexploited for crown rust resistance. A relatively high percentage of A. barbata accessions from the United States Department of Agriculture (USDA) National Small Grains Collection were resistant to a highly diverse crown rust population in recent tests. Tests of 1,099 A. barbata accessions from the Canadian Plant Gene Resources Center not represented in the USDA collection revealed that a similar percentage (11.4%) were at least moderately resistant at the seedling and adult plant stage when tested with a highly diverse bulk inoculum derived from the St. Paul buckthorn nursery. Eighteen accessions were rated as highly resistant or a mix of highly resistant and resistant plants in both seedling and adult plant tests. Three accessions (CN21531 from Italy and CN26271 and CN26305 from Spain) displayed a unique "blotchy" resistant reaction as adult plants. Resistant accessions were found from throughout much of the natural range of A. barbata but the Western Mediterranean and Lebanon had the highest frequency of accessions with broad-spectrum resistance.

Naturally infected seeds from Louisiana were air-heated at 30, 35, and 40 degree C for up to 24 weeks. Seed harvested from bolls inoculated with race 4 of F. oxysporum f. sp. vasinfectum were incubated in dry heat at 60, 70, and 80 degree C for 2 to 14 days, or were immersed in 90 degree C water from 45 s to 3 min. The effects on seed germination and vigor of hot water treatment and a subset of the high-temperature dry heat treatments were also examined in seeds of a Pima (Gossypium barbadense) and an Upland (G. hirsutum) cultivar. Low-or high-temperature dry heat did not eliminate Fusarium spp. from the seed, although seed infection declined more rapidly with higher incubation temperatures. High-temperature dry heat treatments effective in eliminating fusaria also significantly reduced seed vigor in both the Pima and Upland cultivars. Seed from all times of immersion in hot water were less frequently infected with Fusarium spp. than nontreated seed. Incidence of seed infection did not differ significantly among immersion times ranging from 75 s to 3 min. Immersion in 90 degree C water did not reduce germination or vigor at exposure times less than or equal to 120 s and less than or equal to 150 s for seeds of Pima and Upland cotton, respectively. Results from the hot water treatments suggest that thermotherapy may be optimized to provide a tactic to prevent the spread of virulent F. oxysporum f. sp. vasinfectum genotypes into uninfested areas through infected seed.

Trampling significantly reduced final infiltration rate and total infiltration and increased sediment generation from small (0.5 m super(2)) rainfall simulation plots (p < 0.01). Trampling had no effect on time to runoff or time to peak runoff. Trampling had similar effects at sites with both low and very low levels of cyanobacterial biomass, as indicated by chlorophyll a concentrations. We concluded that trampling effects are relatively independent of differences in the relatively low levels of cyanobacterial biomass in this environment. Instead, trampling appears to reduce infiltration by significantly reducing the cover of gravel and coarse sand on the soil surface, facilitating the development of a physical crust during rainfall events. The results of this study underscore the importance of carefully characterizing both soil physical and biological properties to understand how disturbance affects ecosystem processes.

In the elderly, cognitive impairment and incident dementia may be related to the high prevalence of inadequate B vitamin status and to elevations of plasma homocysteine. Plausible mechanisms include homocysteine neurotoxicity, vasotoxicity, and impaired S-adenosylmethionine-dependent methylation reactions vital to central nervous system function.

Inadequate sources of SCYLV resistance limit conventional breeding for resistance. Although transgenics offer the potential for improving SCYLV resistance, previous studies have shown that agronomic performance may be negatively impacted in primary (T0) transgenic lines due to somaclonal variation or transgene position effects. These problems could be overcome or reduced by transgene transfer to sexual progeny. The objectives of this study were to evaluate the utility as parents of two sugarcane genotypes (6-1 and 6-2) previously transformed with the nptII selectable marker and U-SCYLV-CP inserts and to examine the potential of kanamycin sensitivity as a selectable marker in progeny derived from these crosses. 6-1 and 6-2 were used as parents in 31 crosses in four crossing seasons. Flowering characteristics and germination rates of the resulting true seed were comparable with those for the untransformed parent, CP 92-1666, and with other crosses made in the same seasons. Inheritance and function of the nptII insert were tested in 215 seedlings from three crosses through the application of a solution containing 3.0 g L super(-1) kanamycin. Diagnostic PCR confirmed the presence of the nptII insert transgene in 158 (98.1%) of the 161 kanamycin-resistant progeny. Segregation analysis of the data suggests that the nptII insert is independently integrated at two linked loci in 6-1 one of which carries a functional copy of the nptII insert and the U-SCYLV-CP insert. Whereas for 6-2, nptII is inserted at a single, functional loci carrying the U-SCYLV-CP insert. Delta Ct values were determined from real-time PCR data of each insert among progeny testing positive for both inserts using diagnostic PCR. This novel application of the Delta Ct method allowed the determination of copy number relative to the T0 clone without the use of an exogenous control and showed that all copies of the U-SCYLV-CP insert were inherited among almost all progeny of either 6-1 or 6-2. These results demonstrate the utility of T0 transformed sugarcane genotypes for transmission of transgenes to additional sugarcane genotypes and the effectiveness of kanamycin application for screening sexual progeny and will be useful in guiding breeding strategies to improve resistance to the SCYLV through transgenics.

For three fumigation sites located in Florida, cumulative emissions of 1,3-D, MITC and CP were less than 11%, 6% and 2%, respectively. For three fumigation sites in located in Georgia, cumulative emissions of MITC and CP were <13% and 12%, respectively while DMDS emissions varied from 37% to 95%. In the Florida sites, emission peak flux of CP occurred within the first 6h after application. Peak emission of 1,3-D and MITC occurred between 100 and 144h after application. In the Georgia sites where fumigated soil was covered by low density polyethylene (LDPE) plastic, emission peak flux of DMDS and MITC occurred between 12 and 48h after application. Key factors affecting atmospheric emissions were soil moisture, soil tilth and the resistance to fumigant diffusion of the plastic film used to cover soil following application. This study demonstrated reduced atmospheric emissions of agricultural fumigants under commercial production conditions when applied using good agricultural practices including soil water contents above field capacity, uniform soil tilth in the fumigation zone and the use of metalized or virtually impermeable films to further reduce fumigant emissions. The results of this study show a need for regional flux studies due to the various interactions of soil and climate with local agricultural land management practices.

Crop scientists are often interested in canopy rather than leaf water estimates. Comparing canopy fluxes for multiple treatments using micrometeorological approaches presents limitations because of the large fetch required. The goal of this study was to compare leaf-scale to field-scale data by summing soil water evaporation (E) and leaf transpiration (T) versus ET using tower eddy covariance (EC) and scaling leaf transpiration to the canopy level using a two-step scaling approach in soybean [Glycine max (L.) Merr.]. Soybean transpiration represented 89-96% of E + T when combining the soil water evaporation with leaf transpiration on the five measurement days during reproductive growth. Comparing E + T versus ET from the EC system, the E + T method overestimated ET from 0.68 to 1.58mm. In terms of percent difference, the best agreement between the two methods was 15% on DOY 235 and the worst agreement occurred on DOY 234 (41%). A two-step scaling method predicted average ET within 0.01mm of the EC ET between 10:00 and 14:15 on an hourly time-step on DOY 227 under uniform sky conditions and average ET within 0.03mm of the EC ET on DOY 235 under intermittent sky conditions between 10:00 and 15:15. Pooling the scaled-leaf data and comparing them with the measured EC ET data exhibited a strong linear relationship (r =0.835) after accounting for bias (6%). Findings from this study indicate satisfactory results comparing absolute differences are likely not obtainable by summing leaf transpiration with soil water evaporation to calculate canopy water fluxes. However, scaling leaf transpiration provided a robust measure of canopy transpiration during reproductive growth in soybean under these conditions and merits additional study under different climatic and crop conditions.

AN - 812130667; 20817854 AB - Multiparous beef cows were managed to achieve marginal (BCS = 4.7 ± 0.07; n = 106) or good (BCS = 6.6 ± 0.06; n = 121) body condition (BC) to determine the influence of forage environment on BW and BC changes, intramuscular fat percentage (IMF), rump fat (RF), and serum hormones during 2 yr. 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 (P(4)) 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) P(4) 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.

AN - 786978538; 4129184 AB - Seafood was the first class of foods to fall under the 2002 US regulatory requirements for mandatory country-of-origin labelling (COOL). If this regulation created benefits for consumers, filling an information void by demanding information that the market did not, then there should have been an observable response in the demand for seafood. To gauge the impact, we examined markets most likely to respond. We estimated retail demand for shrimp, seafood that in the USA is largely sourced from Southeast Asia and has a history of raising food safety concerns. Our estimated demand systems included standard variables consistent with economic theory - price and expenditure changes, ongoing trends, and seasonality in consumption patterns. The demand systems also accounted for regulations that required country-of-origin labels for some, but not all, foods prior to COOL. Data came from a nationally representative panel of households that record retail food purchases, allowing us to construct relatively high-frequency market data suitable for testing for the presence of even short-lived impacts. Household demographic information allowed us to separately estimate demands by consumers most likely to respond to label information. The demand systems yielded reasonable price and expenditure elasticity estimates, but none of the variables related to COOL revealed evidence of an impact.

Previous studies have hypothesized that one mechanism conferring a competitive advantage to this species is the ability to germinate rapidly at low temperatures in the fall, winter and spring and, therefore, initiate growth and establishment more rapidly than more desirable perennial bunchgrass species. In this experiment, we developed thermal-germination-response models for multiple seedlots of cheatgrass and five perennial grass species. We conducted sensitivity analysis on potential-cumulative-germination response to a 38-year simulation of field-variable conditions of seedbed temperature and moisture. Cheatgrass uniformly germinated at a higher rate, and required significantly less time to complete germination than any of the perennial species for all but the slowest seed subpopulations. A germination-rate-sum index was used to integrate relative response characteristics over time. This index showed that germination rate of the most rapidly germinating subpopulations of cheatgrass was 2-5 times higher than for the other species tested. Model simulations of this type provide a more ecologically relevant basis for seedlot evaluation as they allow comparisons across a wide range of potential conditions that may be experienced in the field.

When comparing this legume to a commonly grown summer legume - cowpeas (Vigna unguiculata), sunn hemp was superior in biomass yield (kg ha super(-1)) and subsequent energy yield (GJ ha super(-1)). In one year of the study after 12 weeks of growth, sunn hemp had 10.7 Mg ha super(-1) of biomass with an energy content of 19.0 Mg ha super(-1). This resulted in an energy yield of 204 GJ ha super(-1). The energy content was 6% greater than that of cowpeas. Eventhough sunn hemp had a greater amount of ash, plant mineral concentrations were lower in some cases of minerals (K, Ca, Mg, S) known to reduce thermochemical conversion process efficiency. Pyrolytic degradation of both legumes revealed that sunn hemp began to degrade at higher temperatures as well as release greater amounts of volatile matter at a faster rate.

Storing biomass wet in the presence of sulfuric acid and the absence of oxygen has been shown to preserve carbohydrates and enhance cellulose conversion but has not been demonstrated at farm-scale. To that end, switchgrass (Panicum virgatum L.) and reed canarygrass (Phalaris arundinacea L.) were pretreated with 18N sulfuric acid with two methods: during bagging (on-line) and thoroughly mixed in a commercial feed mixer (mixed) and both stored for 90days. The two methods, applied at rates from 28 to 54g(kg DM) super(-1) not only helped to preserve biomass substrates under on-farm conditions (anaerobic, ambient temperature and pressure) through inhibition of microbial activity but also enhanced conversion of cellulose to ethanol by simultaneous saccharification and fermentation (SSF) using Saccharomyces cerevisiae. Acid-pretreated substrate yielded 19 and 7 percentage points higher ethanol conversion efficiencies than fresh reed canarygrass and switchgrass, respectively. The on-line method of pretreatment out-yielded the mixed method both as a preservative and as an agent for enhanced cell wall degradation. This result was thought to be an outcome of more uniform acid application as indicated by the on-line method's more consistent pH profile and decreased fermentation products, as compared to the mixed method. Although significant levels of acetate and lactate were present in the biomass following storage, concentrations were not sufficient to inhibit S. cerevisiae in SSFs with a 10% solids loading.

We have identified two dihaploid individuals isolated from among the progeny of a controlled cross between two individuals of the cultivars Alamo and Kanlow. The dihaploid lines were initially distinguished from the parental lines by their reduced heterozygosity and were subsequently confirmed through estimation of C values by flow cytometry and chromosome counts of metaphase root tip squash preparations. These plants are functionally sterile, with floral bracts that remain closed and inviable pollen. They can be easily distinguished from tetraploid individuals by their reduced stature, smaller epidermal cell size, and lower number of chloroplasts per guard cell. Aberrant meiosis in these individuals is evidenced by a lack of regular pairing at diakinesis and metaphase I and suggests that the non-homologous genomes are distinct from one another. The reduced genome size of these dihaploids will facilitate basic genome studies and genetic analyses that are impossible or problematic in polyploid accessions.

Subsequently, synthesis of 1,25(OH)2D3 by 1 alpha -OHase in macrophages has been shown to modulate innate immune responses of macrophages. Despite the numerous in vitro studies that have shown 1 alpha -OHase expression is induced in macrophages, however, evidence that 1 alpha -OHase expression is induced by pathogens in vivo is limited. The objective of this study was to evaluate 1 alpha -OHase gene expression in macrophages and mammary tissue during an in vivo bacterial infection with Streptococcus uberis. In tissue and secreted cells from the infected mammary glands, 1 alpha -OHase gene expression was significantly increased compared to expression in tissue and cells from the healthy mammary tissue. Separation of the cells by FACS9 revealed that 1 alpha -OHase was predominantly expressed in the CD14+ cells isolated from the infected mammary tissue. The 24-hydroxylase gene, a gene that is highly upregulated by 1,25(OH)2D3, was significantly more expressed in tissue and cells from the infected mammary tissue than from the healthy uninfected mammary tissue thus indicating significant local 1,25(OH)2D3 production at the infection site. In conclusion, this study provides the first in vivo evidence that 1 alpha -OHase expression is upregulated in macrophages in response to bacterial infection and that 1 alpha -OHase at the site of infection provides 1,25(OH)2D3 for local regulation of vitamin D responsive genes.

The objective of this work was to develop a new technique to reconstruct missing daily precipitation data in the central part of Chesapeake Bay Watershed using a two-step reconstruction method (RT+ANN) that employed artificial neural networks (ANN) with inputs only from stations that were found to be influential in bootstrap applications of regression trees (RT). The predictive performance of RT+ANN was also compared with those of stand-alone RT and ANN methods. In addition to statistical comparisons of the reconstructed precipitation time series, these resulting data in the Soil and Water Assessment Tool (SWAT) watershed model were used to perform an error propagation analysis in streamflow simulations. The RT provided a transparent visual representation of the similarity between the stations in their daily precipitation time series. Seven years of data from 39 weather stations showed that both RT and ANN provided the reconstruction accuracy comparable to (or better than) published earlier results of precipitation reconstruction. The RT+ANN method significantly improved accuracy and was more robust when compared to RT or ANN methods. This method also provided more accurate and robust SWAT streamflow predictions with reconstructed precipitation.

The identification of PIMT target proteins in plant seeds, where the enzyme is highly active and proteome long-lived, has been hindered by large amounts of isoaspartate-containing storage proteins. Mature seed phage display libraries circumvented this problem. Inclusion of the PIMT co-substrate, S-adenosylmethionine (AdoMet), during panning permitted PIMT to retain aged phage in greater numbers than controls lacking co-substrate or when PIMT protein binding was poisoned with S-adenosyl homocysteine. After four rounds, phage titer plateaued in AdoMet-containing pans, whereas titer declined in both controls. This strategy identified 17 in-frame PIMT target proteins, including a cupin-family protein similar to those identified previously using on-blot methylation. All recovered phage had at least one susceptible Asp or Asn residue. Five targets were recovered independently. Two in-frame targets were produced in Escherichia coli as recombinant proteins and shown by on-blot methylation to acquire isoAsp, becoming a PIMT target. Both gained isoAsp rapidly in solution upon thermal insult. Mutant analysis of plants deficient in any of three in-frame PIMT targets resulted in demonstrable phenotypes. An over-representation of clones encoding proteins involved in protein production suggests that the translational apparatus comprises a subgroup for which PIMT-mediated repair is vital for orthodox seed longevity. Impaired PIMT activity would hinder protein function in these targets, possibly resulting in poor seed performance.

The smoke emissions were measured with a large suite of state-of-the-art instrumentation including an open-path Fourier transform infrared (OP-FTIR) spectrometer for measurement of gas-phase species. The OP-FTIR detected and quantified 19 gas-phase species in these fires: CO sub(2), CO, CH sub(4), C sub(2)H sub(2), C sub(2)H sub(4), C sub(3)H sub(6), HCHO, HCOOH, CH sub(3)OH, CH sub(3)COOH, furan, H sub(2)O, NO, NO sub(2), HONO, NH sub(3), HCN, HCl, and SO sub(2). Emission factors for these species are presented for each vegetation type burned. Gas-phase nitrous acid (HONO), an important OH precursor, was detected in the smoke from all fires. The HONO emission factors ranged from 0.15 to 0.60 g kg super(-1) and were higher for the southeastern fuels. The fire-integrated molar emission ratios of HONO (relative to NO sub(x)) ranged from approximately 0.03 to 0.20, with higher values also observed for the southeastern fuels. The majority of non-methane organic compound (NMOC) emissions detected by OP-FTIR were oxygenated volatile organic compounds (OVOCs) with the total identified OVOC emissions constituting 61 plus or minus 12% of the total measured NMOC on a molar basis. These OVOC may undergo photolysis or further oxidation contributing to ozone formation. Elevated amounts of gas-phase HCl and SO sub(2) were also detected during flaming combustion, with the amounts varying greatly depending on location and vegetation type. The fuels with the highest HCl emission factors were all located in the coastal regions, although HCl was also observed from fuels farther inland. Emission factors for HCl were generally higher for the southwestern fuels, particularly those found in the chaparral biome in the coastal regions of California.

We examined the biological and bioeconomic results of predator management on two adjacent barrier islands, Cayo Costa and North Captiva, along Florida's west coast. Both islands suffered severe nesting losses due to predation and disturbance due to raccoons, while Cayo Costa also was impacted by a large population of feral swine. In 2006, our initial year of study, neither island received predator management and no least tern production occurred on either island, and sea turtle nest predation was 74% and 60%, respectively, for Cayo Costa and North Captiva. Predators were managed in 2007 on Cayo Costa while North Captiva served as an untreated reference island. North Captiva again had no least tern production and sea turtle nest predation was 84%. In contrast, Cayo Costa produced 31 least terns and sea turtle nest predation plummeted to 16%. Both islands received predator management in 2008 when Cayo Costa and North Captiva respectively produced 20 and 55 least terns and had 15% and 0% sea turtle nest predation. The entire costs for predator management by experts over the course of the study was $USD 39,636, while the returns in additional production of least tern young and hatchling sea turtles was valued over $USD 1.1million for a resulting benefit-cost ratio of 27.8.

The transcription levels of the 32 ESTs in response to F. columnare vaccination were then evaluated by quantitative PCR (QPCR). Of the 32 ESTs, 28 were upregulated in at least one vaccinated fish. Of the 28 upregulated ESTs, 12 were consistently induced at least 2-fold higher in vaccinated fish compared to unvaccinated control fish. Of the 12 upregulated genes, three (triglyceride lipase, PIKK family atypical protein kinase, and CCR4-NOT transcription complex subunit 1) were consistently upregulated greater than 3-fold. The 12 consistently upregulated genes also included CD59, polymerase (RNA) I polypeptide C, pyrophosphatase (inorganic) 1, mannose-P-dolichol utilization defect 1, nascent polypeptide-associated complex subunit alpha, hemoglobin-beta, fetuin-B, glyoxalase domain containing 4, and putative histone H3. The 28 upregulated ESTs represent genes with putative functions in the following five major categories: (1) immune response (46%); (2) signal transduction (21%); (3) transcriptional regulation (11%); (4) cell maintenance (11%); and (5) unknown (11%).

The restoration of natural fire regimes has emerged as a primary management objective within fire-prone forests in the interior western US. However, this objective becomes contentious when perceived to be in conflict with the conservation of rare wildlife species. For example, the integration of fire ecology in disturbance-prone forests of eastern Washington with the recovery of the Northern spotted owl has been described as a management dilemma. We intersected modeled spotted owl habitat with mapped priority fuels treatment areas in order to determine the magnitude of the potential conflict between fuels management and owl conservation. Our results show that there is considerable overlap within dry forests between high suitability spotted owl habitat and moderate-high priority fuels treatment areas (34% overlap). However, there is also considerable overlap of lower suitability spotted owl habitat with moderate-high priority fuels treatment areas (35% overlap) providing opportunities to accomplish multiple management objectives if one considers a landscape perspective. We propose that a conservation strategy for the Northern spotted owl in the eastern Cascades consider the following: emphasize landscape restoration of dry forests within which spotted owl habitat is embedded; landscapes considered for restoration need to be large enough to accomodate the effects of fire disturbances and still retain sufficient habitat to support spotted owl populations; and include adaptive management allowing for adequate monitoring and feedback for managers to make needed adjustments.

Here we map tropical dry forest height (RMSE=0.9m, R2 =0.84, range 0.6-7m), and we map foliage height profiles, with a time series of Landsat and Advanced Land Imager (ALI) imagery on the island of Eleuthera, The Bahamas, substituting time for vertical canopy space. We also simultaneously map forest disturbance type and age. We map these variables in the context of avian habitat studies, particularly for wintering habitat of an endangered Nearctic-Neotropical migrant bird, the Kirtland's Warbler (Dendroica kirtlandii). We also illustrate relationships between forest vertical structure, disturbance type and counts of forage species important to the Kirtland's Warbler. The ALI imagery and the Landsat time series are both critical to the result for forest height, which the strong relationship of forest height with disturbance type and age facilitates. Also unique to this study is that seven of the eight image time steps are cloud-cleared images: mosaics of the clear parts of several cloudy scenes. We created each cloud-cleared image, including a virtually seamless ALI image mosaic, with regression tree normalization. We also illustrate how viewing time series imagery as red-green-blue composites of tasseled cap wetness (RGB wetness composites) aids reference data collection for classifying tropical forest disturbance type and age. Our results strongly support current Landsat Program production of co-registered imagery, and they emphasize the value of seamless time series of cloud-cleared imagery.

We quantified litter accumulation in mature melaleuca stands and compared decomposition rates of melaleuca leaves with a sympatric native plant, either Cladium jamaicense (sawgrass) in sawgrass marshes or Pinus elliottii (slash pine) in pine flatwoods habitats that varied in soil types. Total litter accumulation in mature melaleuca forests prior to June 1997 ranged from 12.27 to 25.63Mgha super(-1). Overall, melaleuca leaves decomposed faster in organically rich versus arenaceous soils. Decomposition rates were lower for melaleuca leaves than for sawgrass in both melaleuca-invaded and uninvaded sawgrass marshes. In arenaceous soils of pine flatwoods, melaleuca leaf and pine needle decomposition rates were similar. Complete mineralization of sawgrass leaves occurred after 258weeks, whereas melaleuca leaves had up to 14% and pine foliage had up to 19% of the original biomass remaining after 322weeks. Total carbon (C) in intact decomposing leaves varied slightly, but total nitrogen (N) steadily increased for all three species; the greatest being a fourfold in sawgrass. Increases in N concentrations caused decreases in the C/N ratios of all species but remained within an optimal range (20-30) in sawgrass resulting in higher decomposition rates compared to melaleuca leaves and pine needles (C/N ratio >30). Slower decomposition of melaleuca leaves results in denser litter layers that may negatively affect recruitment of other plant species and impede their establishment in invaded communities.

While guayule traditionally has been cultivated for rubber, more recently it is being cultivated for its hypoallergenic latex. Other uses including termite resistant wood products and as an energy source have also been identified. Major advances have been made since 1970 in the development of improved guayule germplasm. However, the effects of harvesting practices such as cutting height and frequency on latex concentration and yield of newly developed germplasm have not been reported. These results are needed in order to develop production schemes for successful commercialization of guayule. The objectives of this study were to determine the yield and concentration of latex, rubber, and resin of five guayule lines harvested at two cutting heights over 3 years and five harvesting schedules. Harvesting at 100% of plant height gave higher yields than harvesting at 50% of plant height independent of the harvest schedule. Harvesting at 100% after 4 years of growth gave the highest yields, but more research is needed to determine if harvesting on a 2-year schedule may be better for harvesting equipment and extraction equipment. AZ-2 and AZ101 were the largest plants, while N9-3 and 11591 were smaller with AZ-1 intermediate. As indicated in previous studies, the environment plays a large role in determining biomass, latex, rubber, and resin yields in guayule. In the future, optimum harvesting schemes at 100% of plant height may need to be developed for each line and environment.

X C. lanceolata W.T. Aiton; PSR23) is a new oilseed crop adapted to temperate climates that provides a rich source of medium-chain triglycerides. Although prior research indicated cuphea seed yield is not greatly affected by row spacing due to its indeterminate growth, little is known about optimum seeding rate. The present study was designed to test effects of varying seeding rate with row spacing on seed yield. Seed was sown at rates of 4.5, 9.0, and 13.4 kg ha super(-1) in 380, 560, and 740 mm spaced rows in west central Minnesota during 2002 and 2003. Seeding rate did have a significant effect on seed yield and harvest index in 2002, but not in 2003. In 2002, yield under the 9.0 kg ha super(-1) rate was 47 and 19% greater than the highest and lowest seeding rates, respectively. The interaction of row spacing and seeding rate was generally not significant. Cuphea does have good yield plasticity over a range of row spacing and seeding rates. However, results generally indicated that a seeding rate of around 9.0 kg ha super(-1) is near optimum for PSR23 cuphea production and that row spacing less than 740 mm tended to favor greater seed and biomass yields.

Citrus harbors large populations of this insect throughout much of the year in areas where the pest is problematic and improved understanding of the population dynamics and management of H. vitripennis on citrus may be key to its management in the broader agricultural landscape. In turn, the study of population dynamics and the development of management strategies require effective and efficient sampling methods. Within-tree sampling distribution studies revealed that adults and nymphs were more abundant and less variable in the upper strata of citrus trees (>1.5 m). They occurred in greater numbers on the southern quadrants of trees but relative variability did not differ due to cardinal direction. We developed and validated several fixed-precision sequential sampling plans for estimating the density of nymphs and adults of H. vitripennis using a pole bucket sampling method. Based on validation from resampling of independent data sets, Green's sequential sampling model, based on the Taylor's power law, provided the best overall performance in terms of providing mean density estimates with levels of precision equal to or better than the desired precision over a range of possible insect densities. Average sampling costs varied from about 21 to 189 min for a desired precision of 0.25 depending on insect density and whether the goal is to sample nymphs, adults or both stages combined. Further, the sampling plans developed on orange trees were robust, being equally effective on orange and lemon trees and on trees treated or not with insecticides.

Both the wood and needles from J. virginiana were extracted using liquid carbon dioxide (L-CO sub(2)) as well as ethanol (EtOH) and the yields determined. Wood blocks were vacuum impregnated with the extracts and subsequently tested for resistance against eastern subterranean termites (Reticulitermes flavipes) and two species of brown-rot fungi (Gloeophyllum trabeum and Postia placenta). Cedarwood oil (CWO) yields (fresh weight) were 2.3% and 5.9% using L-CO sub(2) (CWO-CO sub(2)) and EtOH (CWO-EtOH), respectively. The yield (i.e., fresh weight) of juniper leaf oil using EtOH was 6.6% of the unground needles. Laboratory termite testing indicated that the ethanol extract of needles was lethal to the termites and resulted in no damage to the test blocks. The CWO-CO sub(2) and the CWO-EtOH treatments were statistically equivalent and both exhibited significant resistance to termite damage compared to untreated controls. The CWO extracts were significantly more effective against G. trabeum than P. placenta. For G. trabeum, the CO sub(2)-derived CWO was statistically equivalent to the uninoculated control. On the other hand, for P. placenta, only the EtOH-derived CWO conferred any significant inhibition. The ethanol extract of the needles did not inhibit either test fungus. These extracts from J. virginianna may provide a renewable source of safe natural wood preservatives.

In Puerto Rico, agricultural abandonment has given way to novel forests dominated by the introduced African tulip tree Spathodea campanulata Beauv. (Bignoniaceae). In this study, I characterized the tree species composition of S. campanulata forests in Puerto Rico as means to evaluate if biotic homogenization is occurring. Non-metric multidimensional scaling was used to examine what variables were related to the large ( greater than or equal to 10 cm diameter at breast height [DBH]), small ( greater than or equal to 2.5 to <10 cm DBH), and juvenile (<2.5 cm DBH) tree species composition of 20 sites. Species composition was strongly related to substrate properties, less related to land use history, and unrelated to spatial attributes. The introduced species component was low (mean = 17%, S.E. = 1.8) and compositional differences were mostly due to native tree species of secondary to old growth forests on equivalent substrates. Animals appear to disperse most species (86%) into these forests yet because of this some introduced species will persist. Although uncommon species were largely absent, recent species establishment is shaped by substrate properties making biotic homogenization in these forests unlikely. The S. campanulata forests of Puerto Rico facilitate native tree species establishment in lands where poor management practices extirpated the original forest. These results highlight the importance of remnant old growth forests or trees that act as seed dispersal sources and facilitate native species recovery in novel forests.

The thousands of dunes scattered across interior eastern Upper Michigan (EUM), more than 500 km east of the forest prairie boundary, must reflect an analogous but more complex climate signal. The destruction of forests extant in the early Holocene must have occurred but expected successional trajectories have not been modeled, much less detected in the robust regional paleorecord. To test and build upon earlier work, we mapped dunes throughout EUM using 10 m DEMs and derived optical ages from samples of quartz sand from the crests of 65 dunes using SAR protocol. In contrast with an earlier finding of a mid-Holocene ( approximately 7.0-5.5 ka) maximum, 1-sigma cumulative probability plots of our optical ages suggest that widespread eolian activity peaked in the early Holocene, approximately 10.5-7.5 ka. This time frame has been identified as one of rapid/drastic environmental change across the upper Midwest (e.g., peak meltwater flux to and from the Superior Basin approximately 9.3 ka; hydrologic closure of the upper Great Lakes approximately 8.9 ka). Given this correspondence, dune chronology seems intuitive but dune distribution and modeling of sand supply change do not. It is clear that sand was supplied to dunes primarily from presently wet, sandy landscapes below a rebound-adjusted surface approximately 245 m asl and that early Holocene pine forests on uplands > approximately 245 m changed in composition but remained largely intact (no dunes formed). Our data record massive dune building in EUM during the driest known period of the Holocene. Nonetheless, they require an integrated biogeomorphic/physical model that accommodates dune building that is tightly stratified among landscape segments underlain by similar sandy substrates.

We coded the six traps as ASYellow, GLYellow, RWYellow, ASACP, ASGreen and MGGreen. The ASYellow, GLYellow and RWYellow traps were a bright yellow color to the human eye but the yellow color of these traps varied in intensity. To the human eye, the ASACP traps were a lime-green color, the MGGreen trap was a fluorescent yellow-green color, and the ASGreen trap was a green color. Spectral reflectance measurements were taken to categorize the color (wavelength) spectrum of each trap. Percent reflectance in the green and yellow wavelength regions was similar among the ASYellow, GLYellow, RWYellow and ASACP traps. Three of the six sticky traps (GLYellow, RWYellow and MGGreen) were treated with a traditional gluey adhesive material. The other three traps were treated with No Mess Sticky Card[TM] adhesive, a hot-melted, pressure-sensitive adhesive material. Trapping studies were conducted in Florida and Texas during April-May comparing four of the traps and during September-October comparing all six traps. Data collected during April-May indicated there were no significant differences in numbers of adults captured on ASGreen, ASYellow, ASACP and GLYellow traps. In seven comparisons of all six traps during September-October, the GLYellow and RWYellow traps each captured significantly fewer adults in one comparison, the MGGreen trap captured fewer adults in two comparisons, and the ASGreen trap captured fewer in three comparisons. There was no evidence that any one of the six traps would be best at detecting psyllids when adult populations are scarce. There was no significant difference between the two adhesive materials with respect to numbers of adults captured on traps.

Microorganisms responsible for the enhanced degradation of fenamiphos were isolated from soil that had a long application history of this nematicide. Bacteria proved to be the most important group of microbes responsible for the fenamiphos biodegradation process. Seventeen bacterial isolates utilized the pure active ingredient fenamiphos as a carbon source. Sixteen isolates rapidly degraded the active ingredient in Nemacur 5GR. Most of the fenamiphos degrading bacteria were Microbacterium species, although Sinorhizobium, Brevundimonas, Ralstonia and Cupriavidus were also identified. This array of gram positive and gram negative fenamiphos degrading bacteria appeared to be pesticide-specific, since cross-degradation toward fosthiazate, another organophosphorus pesticide used for nematode control, did not occur. It was established that the phylogenetical relationship among nematicide degrading bacteria is closer than that to non-degrading isolates.

To test the hypothesis that P. fluorescens induces defense genes in wheat roots, we constructed a custom microarray of 192 oligonucleotides representing 84 wheat root expressed sequence tags (ESTs) homologous to defense/stress genes from Arabidopsis, tomato, rice, and barley, and 11 candidate root developmental genes. The ESTs were selected from existing wheat root EST libraries. Arrays were interrogated with Alexa Fluor 546-labeled transcript (cDNA) populations from roots or coleoptiles of cultivar Finley or lines 442 or 443, near-isogenic for the cold temperature-dependent vrn1A flowering locus, four days after seed inoculation with the take-all-suppressive strain P. fluorescens Q8r1-96. Twenty-two transcripts encoding Ca super(2+-dependent protein kinases, components of the oxidative stress, cold stress and jasmonic acid pathways, and proteins associated with the hypersensitive response were induced or repressed in wheat roots during P. fluorescens interactions. Transcripts encoding pathogenesis-related protein Pr-10a and hypersensitive response protein HRin1 also were induced in coleoptiles. Real-time PCR demonstrated that eleven transcripts were induced in root tissue between 2 and 6 h and remained elevated at 24 h post-inoculation. Our findings suggest that biocontrol P. fluorescens modulates defense/stress gene expression in wheat roots.)

This land is very susceptible to wind erosion during summer fallow because multiple tillage operations during fallow degrade and expose the soil to high winds. We examined possible alternatives to conventional tillage for reducing the emission of windblown PM10 (particulate matter [less-than-or-equals, slant]10 mu m in aerodynamic diameter) during summer fallow. Soil was subject to seven (conventional), five (reduced), three (delayed-minimum), and zero (no) tillage operations between harvest in July 2004 and sowing in August 2005. Sediment catch and PM10 concentration and wind speed profiles were measured after each tillage operation and sowing under simulated high winds (using a portable wind tunnel) to estimate horizontal sediment and PM10 flux. Horizontal sediment and PM10 flux generally decreased with a decrease in number or intensity of tillage operations. No tillage resulted in the lowest sediment and PM10 flux after most tillage operations; no tillage, however, is not yet an economically viable management option for the region. Sediment and PM10 flux were typically lower for reduced and delayed-minimum tillage than for conventional tillage. Our study suggests that PM10 flux can be reduced from agricultural soils during the summer fallow phase of a wheat-fallow rotation by using reduced or delayed-minimum tillage practices. The reduction in PM10 flux from soils will improve air quality during high winds in the region.

Due to short residence times in the fluidized-bed pyrolyzer, required to maximize bio-oil production, the bio-char structure tends to be underdeveloped thereby impacting its full potential application as a value-added co-product. RESULTS: The bio-chars of several substrates from a fluidized-bed fast pyrolyzer and their respective corresponding steam-activated counterparts were characterized for their surface areas and metal ion adsorption (copper, cadmium, nickel and zinc). Surface areas increased with activation from negligible to 136-793 m2 g-1 of material, with concomitant pore development evidenced by scanning electron microscopy and mathematical modeling. Affinity to Cu2+ was highest with adsorption efficiencies for 1 mmol L-1 solutions ranging from 60-85%. Metal ion adsorption performance was feedstock dependent and increased with activation, possibly due to improved access to highly reactive adsorption sites associated with the inorganic material in the feedstock. CONCLUSION: Because of their higher yields and metal ion uptake, broiler litter and alfalfa stems could be the feedstock of choice when considering upgrading fast pyrolysis bio-char for metal ion uptake.

However, rates of VOC emission from silage are not accurately known. In this work, we measured ethanol (a dominant silage VOC) emission from loose corn silage and exposed corn silage particles using wind tunnel systems. Flux of ethanol was highest immediately after exposing loose silage samples to moving air (as high as 220gma2ha1) and declined by as much as 76-fold over 12h as ethanol was depleted from samples. Emission rate and cumulative 12h emission increased with temperature, silage permeability, exposed surface area, and air velocity over silage samples. These responses suggest that VOC emission from silage on farms is sensitive to climate and management practices. Ethanol emission rates from loose silage were generally higher than previous estimates of total VOC emission rates from silage and mixed feed. For 15cm deep loose samples, mean cumulative emission was as high as 170gma2 (80% of initial ethanol mass) after 12h of exposure to an air velocity of 5msa1. Emission rates measured with an emission isolation flux chamber were lower than rates measured in a wind tunnel and in an open setting. Results show that the US EPA emission isolation flux chamber method is not appropriate for estimating VOC emission rates from silage in the field.

In recent years, magnetic separation technology making use of small magnetic beads, has gained immense popularity. Most of these methods rely on the non-specific adsorption of DNA/RNA. However, as presented here, when functionalizing the beads with complementary DNA probes, the target of interest can selectively be isolated. Such sequence specific purification was evaluated for short DNA targets by means of simple fluorescent measurements, resulting in purification efficiencies around 80%. Besides standard fluorescent techniques, a real-time PCR (qPCR) method was applied for monitoring the purification of longer DNA targets. This qPCR method was specifically optimized for directly quantifying the purification efficiency of low concentrated DNA targets bound to magnetic beads. Additionally, parameters possibly affecting the magnetic isolation, including the length of the used capture probe or the hybridization location, were investigated. Using optimized conditions in combination with qPCR, purification efficiencies between 60% and 80% were observed and this over a large concentration window. These data also show the power of a direct qPCR approach to monitor the magnetic isolation of DNA at very low concentrations.

We evaluated the effects of sweep tillage (ST) on near surface soil water dynamics as compared with an untilled (UT) soil during a 7-month period. Plots were established in a fallow field devoid of residue under stubble-mulch tillage management on a clay loam soil. Soil water contents were monitored using time-domain reflectometry at 0.05-0.3 m and using a neutron moisture gage to a depth of 2.3 m. Soil temperature and net radiation was also monitored. During a 114-day period from April through July, tillage with a sweep (0.07-0.1 m) significantly decreased net water storage above 0.3 m soil depth by an average of 12 mm (P = 0.002) as compared with UT plots. After tillage, soil water contents at 0.05 and 0.1 m were significantly (P =0.2 m were not influenced by tillage. Cumulative 3-day evaporation following precipitation events averaged 3.1 mm greater under ST compared with UT (P < 0.014). After extended dry periods, evaporation rates were similar among both treatments (0.3 mm d super(-1)) despite the greater near-surface water contents of UT plots. Although ST plots exhibited 19 mm greater cumulative evaporation from July through October, this was offset by 26 mm greater infiltration compared with UT. A more advanced surface crust development and greater initial water contents were likely responsible for lower cumulative infiltration of UT compared with ST plots. Immediately after tillage, cumulative daily net radiation averaged 22% greater for ST compared with UT surfaces and these differences diminished with time. Increased evaporation under tillage was likely a result of enhanced vapor flow near the surface and greater absorption of radiation by a tilled surface with reduced albedo.

The potential community structure is one where trees dominate, shrub and herbaceous species decline, and rock cover and bare soil area increase and become more interconnected. Research from the Desert Southwest United States has demonstrated areas under tree canopies effectively store water and soil resources, whereas areas between canopies (intercanopy) generate significantly more runoff and erosion. We investigated these relationships and the impacts of tree encroachment on runoff and erosion processes at two woodland sites in the Intermountain West, USA. Rainfall simulation and concentrated flow methodologies were employed to measure infiltration, runoff, and erosion from intercanopy and canopy areas at small-plot (0.5m2) and large-plot (13m2) scales. Soil water repellency and vegetative and ground cover factors that influence runoff and erosion were quantified. Runoff and erosion from rainsplash, sheet flow, and concentrated flow processes were significantly greater from intercanopy than canopy areas across small- and large-plot scales, and site-specific erodibility differences were observed. Runoff and erosion were primarily dictated by the type and quantity of ground cover. Litter offered protection from rainsplash effects, provided rainfall storage, mitigated soil water repellency impacts on infiltration, and contributed to aggregate stability. Runoff and erosion increased exponentially (r2 = 0.75 and 0.64) where bare soil and rock cover exceeded 50%. Sediment yield was strongly correlated (r2 = 0.87) with runoff and increased linearly where runoff exceeded 20mm.h-1. Measured runoff and erosion rates suggest tree canopies represent areas of hydrologic stability, whereas intercanopy areas are vulnerable to runoff and erosion. Results indicate the overall hydrologic vulnerability of sagebrush steppe following woodland encroachment depends on the potential influence of tree dominance on bare intercanopy expanse and connectivity and the potential erodibility of intercanopy areas.

Last-instar nymphs of O. pumilio were individually placed into 96-well microtiter plates and recovered 24-48 h later as virgin adults, fed only on sucrose or water. The procedure yielded low mortalities. Correct identification of the sex of individuals as last-instar nymphs was achieved with 96% accuracy. The availability of food (eggs of Ephestia kuehniella Zeller) and mates for these isolated females was controlled. Unfed adult females, whether mated or not, did not produce defectible yolk protein when assayed by enzyme-linked immunosorbent assay, nor did they show any follicle development when examined microscopically. Fed but unmated females produced a significant, defectible amount of yolk protein, and some oocyte development was observed, but they contained no fully mature eggs. Females that were both fed and mated fell into two categories: 44% produced mature eggs at a mean rate of 6.4 eggs per female, whereas 56% had ovaries similar to those of fed but unmated females. If treated in mixed sex groups, females that were fed and mated contained more yolk protein than those held in pairs, but increasing the sex ratio of groups above 0.5 (males:females) did not result in a significant increase in yolk protein content. Topical treatment of fed females with methoprene, a juvenile hormone analog, did not trigger an increase in yolk protein contents. We conclude that vitellogenesis is a two-stage process in adult female O. pumilio. Early vitellogenesis requires a nutritious adult diet, whereas full vitellogenesis and egg maturation also require mating.

Therefore, the effect of FB on nitrogen metabolism and seed composition was investigated. Nitrate assimilation was evaluated by measuring nitrate reductase activity (NRA) and nitrogen fixation was evaluated by measuring nitrogenase activity and natural abundance of super(15)N/ super(14)N. NRA were significantly (P less than or equal to 0.05) higher in plants that received FB than the control plants. Higher rate of FB (One application of four times of commercial rate) inhibited nitrogen fixation as measured by natural abundance of super(15)N/ super(14)N ratio, but increased NRA. The higher activities of NR and nitrogenase by FB were accompanied with a higher B concentration in leaves. The significant (P<0.0001) enrichment of super(15)N/ super(14)N, accompanied with a higher rate of FB, suggested a possible mechanism where nitrate assimilation may compensate for the decrease in nitrogen fixation. FB increased seed protein by 13.7% and oleic acid by 30.9% compared to the control plants. This alteration was accompanied by a higher B concentration in leaves and seed. The results suggest that FB affects nitrogen metabolism and alters seed compositions, especially protein and unsaturated fatty acids.

The bases used for pH control included NaOH, KOH, NH sub(4)OH, and Na sub(2)CO sub(3). The yield of succinic acid without and with carbon dioxide supplied by an adjacent ethanol fermentor using either corn or barley as feedstock was examined. The carbon dioxide gas from the ethanol fermentor was sparged directly into the liquid media in the succinic acid fermentor without any pretreatment. Without the CO sub(2) supplement, the highest succinic acid yield was observed with Na sub(2)CO sub(3), followed by NH sub(4)OH, and lowest with the other two bases. When the CO sub(2) produced in the ethanol fermentation was sparged into the media in the succinic acid fermentor, no improvement of succinic acid yield was observed with Na sub(2)CO sub(3). However, several-fold increases in succinic acid yield were observed with the other bases, with NH sub(4)OH giving the highest yield increase. The yield of succinic acid with CO sub(2) supplement from the ethanol fermentor when NH sub(4)OH was used for pH control was equal to that obtained when Na sub(2)CO sub(3) was used, with or without CO sub(2) supplementation. The benefit of sparging CO sub(2) from ethanol fermentation on the yield of succinic acid demonstrated the feasibility of integration of succinic acid fermentation with ethanol fermentation in a biorefinery for production of fuels and industrial chemicals.

During winter, lynx preferentially foraged in mature, multilayer forests with Engelmann spruce (Picea engelmannii) and subalpine fir (Abies lasiocarpa) in the overstory and midstory. Forests used during winter were composed of larger diameter trees with higher horizontal cover, more abundant snowshoe hares (Lepus americanus), and deeper snow compared to random availability; multilayer, spruce-fir forests provided high horizontal cover with tree branching that touched the snow surface. During winter, lynx killed prey at sites with higher horizontal cover than that along foraging paths. Lynx were insensitive to snow depth or penetrability in determining where they killed prey. During summer, lynx broadened their resource use to select younger forests with high horizontal cover, abundant total shrubs, abundant small-diameter trees, and dense saplings, especially spruce-fir saplings. Based on multivariate logistic-regression models, resource selection occurred primarily at a fine spatial scale as was consistent with a sight-hunting predator in dense forests. However, univariate comparisons of patch-level metrics indicated that lynx selected homogenous spruce-fir patches, and avoided recent clear-cuts or other open patches. Given that lynx in Montana exhibit seasonal differences in resource selection, we encourage managers to maintain habitat mosaics. Because winter habitat may be most limiting for lynx, these mosaics should include abundant multistory, mature spruce-fir forests with high horizontal cover that are spatially well-distributed.

In rainbow trout, the cDNA sequences of two E3 ubiquitin ligase F-box proteins, FBXO32 and FBXO25, were characterized and their expression across tissues in response to feed deprivation was determined. The cDNA sequence for FBXO32 encodes a protein 355 amino acids long and is 97% identical to the homologous protein in salmon, 85% to zebrafish and 72% identical to both human and mouse. The cDNA for FBXO25 encodes a protein 356 amino acids in length that is 98% identical to the homologous protein in salmon, 84% to zebrafish, and 75% to human. After 28 days of feed deprivation, FBXO32 expression increased by approximately 13-fold, 3-fold, and 5-fold in white muscle, red muscle, and intestine, respectively (P < 0.05). Expression of FBXO32 and FBXO25 in kidney decreased 0.3-fold and 0.2-fold, respectively, and FBXO25 expression decreased by 0.2-fold in liver (P < 0.05). These results indicate that these protein sequences are conserved and suggest that the up-regulation of FBXO32 is associated with skeletal and smooth muscle atrophy that occurs during fasting.

Most mosquito colonies require substantial effort to maintain, including frequent bloodmeals for optimal performance. Successful cryopreservation of mosquitoes continues to be elusive. Although using diapause as a storage mechanism is an option for mosquito preservation, several obstacles include the lack of a well-characterized diapause or the inability of some species to enter diapause. Thus, other options for preservation are needed. To address this issue, we investigated the use of long-term low-temperature storage in the absence of diapause for adults of the northern house mosquito, Culex pipiens L. Our results indicate that although male longevity is not substantially increased by cold storage, female longevity is dramatically increased by storage at lower temperatures. When mated before storage, females remain reproductively viable after at least 10 wk of storage, although at reduced levels. These results indicate that cold storage without diapause induction is a viable option for colony maintenance in vector biology laboratories.

However, the mechanistic role of magnesium in baculovirus transmission is unknown. To investigate the possible role of host response factors in baculovirus transmission, suppression subtractive hybridization was used to identify genes differentially transcribed after magnesium exposure in Cx. quinquefasciatus larvae. Suppression subtractive hybridization was performed in both directions enriching for cDNAs differentially transcribed between a nonmagnesium larval control and magnesium (15 mM MgSO4) treatment of Cx. quinquefasciatus larvae held for 1 h at 27 degree C. Clones from differentially transcribed genes were evaluated by sequencing, and relative gene transcription levels were analyzed using quantitative real-time polymerase chain reaction quantitative real-time polymerase chain reaction. Target transcripts up/downregulated by magnesium included Cx. quinquefasciatus troponin C, isocitrate dehydrogenase, allergen, cytochrome b5, chymotrypsinogen, apolipophorins, tryptase gamma, carboxylesterase, prolylcarboxypeptidase, imaginai disc growth factor, aldehyde dehydrogenase, tropomyosin-1, chitotriosidase, heat shock protein 70 B2, inorganic phosphate cotransporter, and many other hypothetical protein genes. Magnesium can alter gene transcription in a vector mosquito population, and understanding this process can provide insight into the mechanistic role of magnesium in baculovirus transmission.

In a study that began in 2007, we marked 725 ring-billed gulls (Larus delawarensis) with Bondcote royal blue, green, yellow, or orange patagial tags. Reports we gathered over 2years indicated approximately a 3.4[ratio]1 bias in resighting rate toward yellow or orange tags. The observed bias is inconsistent with color-associated visibility bias or differential mortality among color-tagged breeding adults. Potential behavioral effects of tag color on individuals and conspecifics should be considered by biologists when planning marking studies.

Culex mosquitoes feed on a wide range of nectars consisting of mostly carbohydrates and amino acids, however, little is known about the utilization and effects of these different carbohydrates and their accompanying amino acids on longevity. Culex quinquefasciatus larvae were reared on low- and high-quantity food diets to produce adults that were nutritionally representative of wild-caught and laboratory-reared mosquitoes. Emerging adults reared on low- or high-quantity food diets as larvae were then provided Lantana camara nectar mimics containing mixtures of carbohydrates and amino acids to evaluate effects of nectar amino acids on longevity. Carbohydrates (with or without amino acids) were a critical component of the adult diet, and in their absence, adult mosquitoes died within 3-5 days. The nectar mimic that contained both carbohydrates and amino acids did not increase adult longevity of males originating from either poorly or well-fed larvae. However, females receiving adult diets containing both carbohydrates and amino acids lived 5% longer than females fed adult diets with only sugar.

Pyrolysis was carried out in the absence and presence of two heterogeneous catalysts, an acidic zeolite (HZSM-5) catalyst and a mixed metal oxide catalyst (CoO/MoO sub(3)). Non-catalytic Py-GC/MS was used to identify the lignin as characterized by their H-, G- or S-lignin makeup and also served as the control basis to evaluate the effect of the said catalysts on the production of aromatic hydrocarbons from these lignin sources. Experiments show that the selectivity to particular aromatic hydrocarbons varies with the composition of the lignin for both catalysts. The major pathway for hydrocarbon production over HZSM-5 is likely increased depolymerization efficiency that releases and converts the aliphatic linkers of lignin to olefins followed by aromatization. Simple phenols produced from the deconstruction of the lignin polymer are likely to be a source of zeolite deactivation. The CoO/MoO sub(3) is likely to produce aromatic hydrocarbons through a direct deoxygenation of methoxyphenol units.

One possible strategy for reducing nitrate export is the use of denitrification bioreactors. A variety of experimental bioreactor designs have been shown to reduce nitrate losses in drainage water for periods up to several years. This research reports on the denitrification activity of a wood chip-based bioreactor operating in the field for over 9 years. Potential denitrification activity was sustained over the 9-year period, which was consistent with nitrate removal from drainage water in the field. Denitrification potentials ranged from 8.2 to 34mgNkga1 wood during the last 5 years of bioreactor operation. Populations of denitrifying bacteria were greater in the wood chips than in adjacent subsoil. Loss of wood through decomposition reached 75% at the 90-100cm depth with a wood half-life of 4.6 years. However, wood loss was less than 20% at 155-170cm depth and the half-life of this wood was 36.6 years. The differential wood loss at these two depths appears to result from sustained anaerobic conditions below the tile drainage line at 120cm depth. Pore space concentrations of oxygen and methane support this conjecture. Nitrous oxide exported in tile water from the wood chip bioreactor plots was not significantly higher than N2O exports in tile water from the untreated control plots, and loss of N2O from tile water exiting the bioreactor accounted for 0.0062kgN2O-Nkga1 NO3-N.

The fungi that produce ZEA are found worldwide, particularly in cereal grains and derived products. This has prompted many surveys to detect these compounds in commodities and foods. As a result, the widespread occurrence of ZEA in foods is well documented. Previous summaries including extensive reports by the Joint FAO/WHO Expert Committee on Food Additives (JECFA), the European Commission's Scientific Cooperation on Questions Relating to Food (SCOOP), and others, have provided significant information on the occurrence of ZEA in commodities and foods. Publication of occurrence data has continued at a rapid pace, and certain of that data, as well as highlights from previous intake and exposure assessments, are summarised herein. Comparing estimates of intake (exposure) with previous estimates of tolerable daily intakes, suggests that, for many of the countries where exposure assessments have been done, the populations are exposed to levels that would be considered safe. The situation may be different in populations that consume large quantities of foods that are susceptible to contamination, or in instances where contamination is atypically high. For much of the world estimates of exposure have not been reported, meaning that for much of the world, the true extent of the relevance of ZEA to human health remains uncharacterised.

In this study, we compared several organic and conventional potato farms in Colorado for differences in soil nutrients and microbial communities using 454 pyrosequencing of the 18S ribosomal RNA gene. Organic farms showed a slightly higher diversity and evenness within the microbial community compared with conventional farms. No difference in the number of observed or estimated total operational taxonomic units (OTUs) was observed between management strategies. However, the relative abundance of 16 OTUs (3% genetic distance) differed between the organic and conventional farms, with seven increasing and nine decreasing in organic farms. A variety of known potato fungal pathogens (e.g., Alternaria spp., Ulocladium spp., and Pythium ultimum) were detected in the soil, including three different OTUs (3% genetic distance) with a high homology to the early blight pathogen Alternaria solani. Relative abundance for Alternaria spp. was higher in conventional farms (relative abundance 30.15 versus 7.8%), whereas the relative abundance for P. ultimum was higher in organic farms (relative abundance 0.25 versus 0.05%). Quantitative polymerase chain reaction, using primers specific for A. solani, Phoma foveata, and Pythium ultimum, yielded similar results to the pyrosequencing, validating the use of pyrosequencing data for the quantification of OTU relative abundances.

Tissue-blot nucleic acid hybridization assays were developed for simple, high-throughput detection of these three viruses as well as Cucurbit yellow stunting disorder virus (CYSDV), which was first reported in Florida in 2008. To determine virus distribution within plants, we collected 80 entire plants just before or during the harvest period in a systematic sample, 20 each on 11 April, 18 April, 26 April, and 3 May 2007, from a fruiting commercial watermelon field near Immokalee, FL showing symptoms of infection by SqVYV, CuLCrV, and PRSV-W and, possibly, CYSDV. This was followed by a sampling of five plants collected at harvest showing symptoms of virus infection on 11 October 2007 in a different commercial planting located in Duette, FL. Tissue prints were made from cross sections of watermelon plants from the crowns through the tips at 0.6-m intervals on nylon membranes and nucleic acid hybridization assays were used for virus detection. Results from testing crown tissue showed that SqVYV, CuLCrV, and PRSV-W were present in -37, 44, and 54%, respectively, of the 80 plants collected over the four sampling dates from the first field. For individual vines diagnosed with SqVYV, the distribution of SqVYV in vine tissue decreased proportionately with distance from the crown. The probability of detecting SqVYV was 70% at the base of the vine compared with 23% at the tip of the vine. In contrast, CuLCrV tended to be more evenly distributed throughout the plant, with -10% higher probability of detection at the growing tip relative to the crown of the plant. The distribution of PRSV-W resembled that of SqVYV but with -20% higher probability of detection at the tip of the vine. Similar trends were detected in the smaller sampling; however, CYSDV was also detected in three of the plants. Overall, the results indicated that SqVYV and PRSV-W were distributed differently than CuLCrV in watermelon plants, and this difference has implications on how samples should be collected and may affect vector acquisition and transmission of these viruses.

Published mitochondrial genome sequences of V. dahliae (DQ351941) were used to design primers for amplification of spacer regions for assessment of mitochondrial haplotype differences among isolates. Five regions were examined (5,229 bp, or 19% of the total genome size) for 30 isolates representing a range in vegetative compatibility group (VCG), host, and geographic origin. Observed differences among isolates were due to single nucleotide polymorphisms, different numbers of bases in specific homopolymeric regions, and copies of subrepeated sequences. When the differences observed for each locus were totaled there were 28 total groupings; when the results of each locus for individual isolates were combined there were 15 mitochondrial haplotypes. Some of the observed groupings correlated with VCG. For example, five VCG-1A and VCG-1B isolates from California, Spain, and Greece had identical haplotypes; however, this was not observed for VCG-2 or VCG-4 isolates. While some VCG-2 isolates also were identical and fell into a single haplotype, five haplotypes were found for this group (five other haplotypes were observed for other isolates that had not been characterized to VCG but grouped with VCG-2 isolates in the phylogenetic analysis). Likewise, five VCG-4 isolates fell into four mitochondrial haplotypes, one of which was identical to the largest VCG-2 grouping. A heterokaryon self-incompatible isolate that was reported in the literature to cluster with VCG-2 isolates by amplified fragment length polymorphism analysis was identical with VCG-1 isolates for four of the five loci, but was intermediate between VCG-1 and VCG-2 in the haplotype analysis. Phylogenetic analysis with these regions revealed the mitochondrial background of VCG-1 and VCG2-B to be monophyletic but VCG-2A and VCG-4 could not be separated. The results obtained indicate that there is variation in mitochondrial haplotypes and this type of analysis may be a useful for characterization of isolates. While data from all five regions was used for the haplotype separation in this study, depending on the VCG or the level of variability observed within a population it is possible to use fewer loci.

MFSV was transmitted to maize, wheat, oat, rye, barley, foxtail, annual ryegrass, and quackgrass by G. nigrifrons. Parameters affecting efficiency of MFSV acquisition (infection) and transmission (inoculation) to maize were evaluated using single-leafhopper inoculations and enzyme-linked immunosorbent assay. MFSV was detected in -20% of leafhoppers that fed on infected plants but <10% of insects transmitted the virus. Nymphs became infected earlier and supported higher viral titers than adults but developmental stage at aquisition did not affect the rate of MFSV transmission. Viral titer and transmission also increased with longer post-first access to diseased periods (PADPs) (the sum of the intervals from the beginning of the acquisition access period to the end of the inoculation access period). Length of the acquisition access period was more important for virus accumulation in adults, whereas length of the interval between acquisition access and inoculation access was more important in nymphs. A threshold viral titer was needed for transmission but no transmission occurred, irrespective of titer, with a PADP of <4 weeks. MFSV was first detected by immunofluorescence confocal laser scanning microscopy at 2-week PADPs in midgut cells, hemocytes, and neural tissues; 3-week PADPs in tracheal cells; and 4-week PADPs in salivary glands, coinciding with the time of transmission to plants.

However, in the genomic sequence for Camp. coliRM2228, two rRNA operons have an ISR that is characteristic of Camp. coli, and the third operon is characteristic of Camp. jejuni. The aim of this study was to determine the prevalence of ISR heterogeneity in these organisms.Methods and Results: PCR primers were designed to yield a 327-base pair (bp) product for Camp. coli and 166-bp product for Camp. jejuni. A strain like Camp. coliRM2228 should yield products of both sizes. DNA from a panel of Camp. coli (n = 133) and Camp. jejuni (n = 134) isolates were tested. All of the isolates yielded products of the predicted size for the species. To verify the data for Camp. coliRM2228, each ribosomal operon from the isolate was individually amplified by PCR and tested with the ISR primer pair. Products of both sizes were produced as predicted.Conclusions: The cross-species heterogeneity of the ISR seen in Camp. coliRM2228 is uncommon.Significance and Impact of the Study: The heterogeneity must have been caused by horizontal gene transfer at a frequency lower than predicted from housekeeping gene data. Thus, it can be expected that species identification based on the ISR can be confused in rare isolates.

We discuss reasons for the existence of spatial effects in vehicle ownership, and note potential implications for policymakers. Our results point to the importance of spatial relationships in transportation research and highlight the hazards of ignoring their role in affecting transportation outcomes. For example, if vehicle type choice is affected by neighborhood spillovers, agencies that regulate traffic flow and road safety could tailor their choice projections and policy tools to account for such interdependence.

A GII.4 virus was used for the detailed binding kinetics study and a panel of genogroup I (GI) NoVs, genogroup II (GII) NoVs and recombinant NoVs (rNoVs) were used for specificity and binding efficiency assays. We determined that NoV can be captured after 15 min of incubation with PGM-MB, and virus recovery efficiency is decreased after extended incubation times. rNoV binding as measured by ELISA and NoV recovery as measured by quantitative reverse transcriptase-polymerase chain reaction (RT-PCR), were both enhanced significantly at acidic pH conditions. rNoV binding to PGM as measured by ELISA was increased up to 66%. While real-time RT-PCR analyses suggest that NoV could be concentrated as much as 1000-fold at neutral pH, up to 3.4-fold further increase of NoV recovery was achieved by adjusting the pH of the sample to 3.0-4.2. Variation between GI and GII viral binding to the PGM-MB at basic pH was observed. All five GI rNoVs tested and 6 of 9 GII rNoVs were captured by PGM. All eight GI strains tested were concentrated by PGM-MB, ranging from 28-fold (GI.4) to 1502-fold (GI.1). Eleven of 13 GII strains were concentrated from 30-fold (GII.5) to 1014-fold (GII.4, lab strain) by PGM-MB. GI and GII rNoVs viral capsid proteins were recovered with high salt conditions, but results were inconsistent for whole virus recovery.Conclusions: All GI and 85% of GII NoVs tested could be captured and concentrated by PGM-MB method. The binding occurred rapidly and was enhanced at low pH.Significance and Impact of the Study: These results facilitated development of a prototype method for sensitive detection of NoV in samples requiring larger volumes.

AN - 760153162; 13667648 AB - The potential role of two species of pack rats (Neotoma albigula and Neotoma micropus) as keystone ecological engineers was examined by estimating the species diversity of invertebrates living in the nest middens, and nitrogen mineralization rates in soils associated with the middens. Although pack-rat middens in tarbush (Flourensia cernua) shrublands were smaller than those in creostebush (Larrea tridentata) shrublands, they housed a higher abundance and diversity of arthropods. The Neotoma spp. middens were an important microhabitat for crickets (Gryllus sp.), wolf spiders (Lycosa spp.), and lycid beetle larvae (Lycidae) in all of the shrub habitats. There were five arthropod taxa that occupied all middens in the creosote-bush shrubland, and 12 arthropod taxa that occupied all middens in the tarbush shrubland. Soils associated with pack-rat middens had significantly higher soil organic-matter content than reference soils. Nitrogen mineralization was significantly higher in soils associated with pack-rat middens than in reference soils. Neotoma spp. create habitats with moderate microclimates that are essential for several invertebrates, thus contributing to maintenance of biodiversity. The effects of middens on soil organic matter and nitrogen mineralization create nutrient-rich patches. Neotoma spp. affect biodiversity and critical ecosystem processes, thus supporting the designation of keystone ecological engineers.

Like in many regions of the world, the lack of water is beginning to impact production of tree fruit such as peaches in the San Joaquin Valley of California. This is an area where irrigation is the only source of water for agricultural crops in the summer growing season. A two-year field study was conducted to assess plant water stress using infrared canopy temperature measurements and to examine its feasibility for managing postharvest deficit irrigation of peach trees. Twelve infrared temperature sensors were installed in a mature peach orchard which received four irrigation treatments: furrow and subsurface drip irrigation with or without postharvest water stress. During the two-year period, measured midday canopy to air temperature differences in the water-stressed postharvest deficit irrigation treatments were in the 5-7 degree C range, which were consistently higher than the 1.4-2 degree C range found in the non-water-stressed control treatments. A reasonable correlation (R 2 =0.67-0.70) was obtained between stem water potential and the canopy to air temperature difference, indicating the possibility of using the canopy temperature to trigger irrigation events. Crop water stress index (CWSI) was estimated and consistently higher CWSI values were found in the deficit irrigation than in the control treatments.

Canopy volumes and foliar super(15)N ratios (d super(15)N) of Larrea tridentata were related to average soil water availability (q sub(matric)) and the modeled duration of available soil water (consecutive days q sub(matric) > -6.0 MPa). Weakly developed soils on young (Holocene) alluvial deposits had the longest duration (129 d) and highest q sub(matric) (-1.8 MPa), compared to soils with moderate horizon development in intermediate-aged (late Pleistocene) deposits (80 d, -4.3 MPa) and in soils with strong horizons on old (mid-late Pleistocene) deposits (20 d, -3.2 MPa). Plant canpoy volume was highest in weakly developed soils (2.23 m super(3) c 0.342 SE) than in moderately or strongly developed older soils (0.57 m super(3) c 0.082 SE; 0.56 m super(3) c 0.123 SE, respectively). The fourth site possessed possessed a soil with a silt- and clay-rich horizon beneath a strong stone pavement, and had the shortest, most water-limited regime (13 d; -5.5 MPa) and smallest plant canopies (0.46 m super(3) c 0.073 SE). Foliar d super(15)N variation was better explained by average q sub(matric) (R super(2) = 0.69; p , 0.001) than duration of available soil water (R super(2) = 0.49; p , 0.001). Together, these findings suggest soil hydrological regimes establish thresholds for plant growth, and plant N-dynamics are tightly coupled to desert soil hydrological characteristics.

The increasing number of annual Flu cases, coupled with the recent Flu pandemic, has amplified concerns about the impact of Flu on human and animal health. Similar to humans, Flu is problematic in pigs, not only as a primary pathogen but as an agent in polymicrobial pneumonia. Bordetella species play a role in mixed infections and often colonize the respiratory tract without overt clinical signs. Pigs serve as a valuable animal model for several respiratory pathogens, including Bordetella (Bb) and Flu. To investigate Flu/Bb coinfection pathogenesis, a study was completed in which pigs were inoculated with Flu-only, Bb-only or both agents (Flu/Bb). Results indicate that Flu clearance is not altered by Bb infection, but Flu does enhance Bb colonization. Pulmonary lesions in the Flu/Bb group were more severe when compared to Flu-only or Bb-only groups and Bb did not cause significant lesions unless pigs were coinfected with Flu. The type I interferon response was elevated in coinfected pigs, but increased expression of antiviral genes Mx and PKR did not appear to enhance Flu clearance in coinfected pigs, as viral clearance was similar between Flu/Bb and Flu-only groups. IL-1b and IL-8 were elevated in lungs of coinfected pigs, correlating to the days enhanced lesions were observed. Overall, Flu infection increased Bb colonization and enhanced production of proinflammatory mediators that likely contribute to exacerbated pulmonary lesions.

AN - 759132862; 20387062 AB - Rice (Oryza sativa L.) is one of the most important food crops worldwide. However, it is also a valuable tool in assessing toxicity of organic and inorganic compounds. For more than 20 years, it has been an approved species for standardized phytotoxicity experiments. The objective of this study is to determine germination and radicle (root) and coleoptile (shoot) growth of rice seeds exposed to three insecticides and two herbicides, commonly used in the agricultural production landscape. Although no germination effects of pesticide exposure were observed, significant growth effects were noted between pesticide treatments. Coleoptile growth was significantly (p ≤ 0.05) lowered in metolachlor/atrazine mixture, diazinon, and lambda-cyhalothrin exposures when compared with controls. Radicles of fipronil-exposed seeds were significantly larger (p ≤ 0.05) when compared with controls. This research contributes to the phytotoxicity assessment database, in addition to laying the foundation for the use of rice as a phytoremediation tool for agricultural pesticide runoff.

AN - 758834592; 20656966 AB - Crossbred steers were grazed in the spring and early summer on endophyte-infected (Neotyphodium coenophialum), Kentucky-31 tall fescue (Lolium arundinaceum) pastures to evaluate effects and interactions of feeding pelleted soybean hulls (PSBH) and steroid hormone implants (SHI) on steer performance, serum prolactin, and hair coat ratings (HCR). 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.

Demand for natural pesticides such as essential oils for organic farming continues to increase. We examined the antimicrobial activity of several essential oils against Escherichia coli O157:H7 in soil. Two essential oils (cinnamaldehyde and eugenol), two bio-pesticides (Ecotrol and Sporan) containing essential oils, and an organic acid (acetic acid) at 0.5%, 1.0%, 1.5% and 2.0%, were mixed with organic sandy soil and inoculated with five different strains of E. coli O157:H7. Soils were incubated at room temperature (22 C) and samples obtained at 1, 7 and 28 days were enumerated to determine survival. E. coli O157:H7 populations in soil were reduced by up to 5 log cfu/g after 24 h incubation at room temperature with 2% cinnamanaldehyde, Ecotrol, Sporan or vinegar. Reduction in E. coli O157:H7 by eugenol was not significantly different from control. Overall, E. coli O157:H7 strain 4406 was the most sensitive of all the five strains tested and cinnamaldehyde was superior to other treatments in reducing E. coli O157:H7 in soil. In general, increases in essential oil concentrations corresponded to reduced survival of E. coli O157:H7 with all oils used in this study. The results suggest that oils can reduce potential contamination of fresh organic produce inadvertently contaminated by soil.

The objective of this study was to evaluate the effects of glycerol on ruminal free-fatty acid (FFA) production rates and in vitro fermentation kinetics of alfalfa hay. In vitro incubations demonstrated 48% and 77% reductions in rates of FFA accumulation in incubations supplemented with 2% and 20% glycerol as compared to controls. In vitro incubations with alfalfa hay demonstrated that increasing levels of glycerol did not affect NDF digestibility of the hay. Additionally, increasing amounts of glycerol decreased the acetate to propionate ratio in the rumen. These results suggest that inhibiting bacterial fat degradation may promote ruminal passage of total lipid, thereby providing greater proportions of beneficial unsaturated fat for incorporation into beef products.

Compounds were dissolved in model wine solutions with (and without) catechol. Solutions were examined and then contrasted by absorbance measurements, phloroglucinolysis, and subsequent HPLC analysis. Oxidation of these monomers and polymers revealed significant colour changes (measurable increase in colour density). The presence of catechol increased the half-life of catechin, but the opposite was observed for total skin and seed proanthocyanidins. Skin and seed proanthocyanidin degradation half-life decreased with the addition of catechol. In general, based on second order rate reactions, total subunits of seed proanthocyanidin solutions degraded faster than that of skin proanthocyanidin solutions. As expected, there were decreases of measurable phenolics in both monomer and polymer solutions. Under the study conditions, flavanol monomer and polymer oxidation was chiefly dependant upon initial solution concentration.

Sand movement was detected with piezoelectric saltation sensors, and these data were used to calculate saltation activity and threshold wind speeds for the two sites. Significant blowing events were observed on nine days of this 112-day study, and it was only during these active periods that threshold values could be calculated. During periods of sand transport, threshold values were calculated every 5aamin. Average threshold values typically exceeded 10.5aam/s at both sites; these are about twice those measured previously at a less vegetated dune site in West Texas. Less saltation activity occurred at the Gnome site compared with the Near Field site, especially during April; and while this can be partially attributed to differences in wind speed, additional studies are needed to evaluate other important factors such as the influence of undulating terrain and complex vegetation. Nevertheless, the results demonstrate the feasibility of long-term unattended monitoring of wind erosion activity in remote locations and that reliable and consistent estimates of threshold velocity can be obtained in complex desert environments using the time-fraction-equivalence principle.

Conservation areas often encompass both terrestrial and aquatic resources. Government policy makers and natural resource managers must often consider a complex landscape matrix and need accurate, fine-scale information on the distribution of species and habitats in order to develop conservation management plans. An integrated terrestrial and aquatic GAP analysis project is addressing this need. The goal is to develop a comprehensive set of databases on Puerto Rico and the US Virgin Islands' freshwater and marine resources - including habitat description and mapping, species distributions and conservation status, and protected areas and conservation priorities - combined with existing Puerto Rico and USVI terrestrial GAP databases, to conduct integrated analyses of gaps in conservation protection. As a start to this project we have complied an annotated list of over 1200 animal species associated with terrestrial and aquatic habitats in Puerto Rico and the US Virgin Islands. We have modeled the distributions of over 200 of the terrestrial species and are working on 200 aquatic species and their habitat distributions. This will be used to develop species range maps and predicted distributions, which will then be assessed in terms of the degree to which species and habitats are protected for conservation by reserves and other protected areas.

Therefore, the objective of this study was to investigate the effects of soybean-corn (Zea mays L.) rotations on seed protein, oil, and fatty acids composition on soybean. Soybeans were grown at Stoneville, MS, from 2005 to 2008 in five different scheduled cropping sequences. In 2007, following three years of rotation with corn, seed oleic acid percentage was significantly higher in any crop rotation than continuous soybean. The increase of oleic fatty acid ranged from 61 to 68% in 2007, and from 27 to 51% in 2008, depending on the rotation. The increase of oleic acid was accompanied by significant increases in seed concentrations of phosphorus (P), iron (Fe), and boron (B). In 2007, the increase of P ranged from 60 to 75%, Fe from 70 to 72%, and B from 34 to 69%. In 2008, the increase of P ranged from 82 to 106%, Fe from 32 to 84%, and B from 62 to 77%. Continuous soybean had higher linoleic:oleic ratio and linoleic: palmitic + stearic + oleic ratio, indicating that relative quantity of linoleic acid decreased in rotated crops. The total production of protein, oil, stearic and oleic fatty acids was the lowest in continuous soybean. The total production of palmitic acid was inconsistent across years. The results show that soybeancorn rotation affects seed composition by consistently increasing seed oleic fatty acid, P, Fe, and B concentrations. Higher oleic acid, unsaturated fatty acid, is desirable for oil stability and long-shelf storage. The mechanisms of how these nutrients are involved are not yet understood.

In this study, we sought to assess the real-world applicability of fast, low-pressure GC-time-of-flight MS (LP-GC/TOFMS) for the identification and quantification of 150 pesticides in tomato, strawberry, potato, orange, and lettuce samples. Buffered and unbuffered versions of QuEChERS (which stands for "quick, easy, cheap, effective, rugged, and safe") using dispersive solid-phase extraction (d-SPE) and disposable pipette extraction (DPX) for clean-up were compared for sample preparation. For clean-up of all sample types, a combination of 150 mg MgSO sub(4), 50 mg primary secondary amine (PSA), 50 mg C sub(18), and 7.5 mg graphitized carbon black (GCB) per mL extract was used. No significant differences were observed in the results between the different sample preparation versions. QuEChERS took 32 injections in 8 h. Overall, >126 analytes gave recoveries (3 spiking levels) in the range of 70-120% with <20% RSD. The results indicate that LP-GC/TOFMS for GC-amenable analytes matches UHPLC-MS/MS in terms of sample throughput and turnaround time for their routine, concurrent use in the analysis of a wide range of analytes in QuEChERS extracts to achieve reliable quantification and identification of pesticide residues in foods.

A series of multispectral images over a field planted cotton, corn and soybean were obtained by a Geospatial Systems MS4100 camera mounted on an Air Tractor 402B airplane equipped with Camera Link in a Magma converter box triggered by Terraverde Dragonfly flight navigation and imaging control software. The field crops were intentionally stressed by applying glyphosate herbicide via aircraft and allowing it to drift near-field. Aerial multispectral images in the visible and near-infrared bands were manipulated to produce vegetation indices, which were used to quantify the onset of herbicide induced crop stress. The vegetation indices normalized difference vegetation index (NDVI) and soil adjusted vegetation index (SAVI) showed the ability to monitor crop response to herbicide-induced injury by revealing stress at different phenological stages. Two other fields were managed with irrigated versus nonirrigated treatments, and those fields were imaged with both the multispectral system and an Electrophysics PV-320T thermal imaging camera on board an Air Tractor 402B aircraft. Thermal imagery indicated water stress due to deficits in soil moisture, and a proposed method of determining crop cover percentage using thermal imagery was compared with a multispectral imaging method. Development of an image fusion scheme may be necessary to provide synergy and improve overall water stress detection ability.

The Mississippi Delta Management Systems Evaluation Area (MSEA) project was designed to assess the effects of land management practices on water quality in three small oxbow lake watersheds; Thighman (1338ha, 16ha lake); Beasley (915ha, 25ha lake); and Deep Hollow (132ha, 8ha lake). Monthly water samples were monitored for enzymatic activity (fluorescein diacetate hydrolysis, alkaline phosphatase, and substrate utilization), chemical and physical analysis (suspended solids, dissolved organic carbon, pH, nitrate, ammonium, orthophosphate, and electrical conductivity), phytoplankton and bacterioplankton populations. All of these parameters were influenced by the intrinsic nature of the watersheds, with some parameters shifting as management changes were imposed on the surrounding agricultural fields. Thighman lake water typically maintained the highest suspended solid levels, dissolved organic carbon, algal and bacterial populations, enzyme activities, and heterotrophic metabolic indexes. Introduction of reduced tillage practices and glyphosate-resistant crops in Beasley watershed resulted in lower levels of suspended sediments, but had minimal impact on overall ranking of biochemical or microbiological properties. Likewise, conversion of Deep Hollow watershed from reduced tillage to conventional tillage had little effect on suspended sediment, and most microbial activity parameters remained intermediate. However, canonical analysis indicated dynamic changes in the microbial community, suggesting that biological parameters of lake water quality were affected by changes in crop and soil management practices.

The Warner Mountains of northeastern California on the Modoc National Forest experienced a high incidence of tree mortality (2001-2007) that was associated with drought and bark beetle (Coleoptera: Curculionidae, Scolytinae) attack. Various silvicultural thinning treatments were implemented prior to this period of tree mortality to reduce stand density and increase residual tree growth and vigor. Our study: (1) compared bark beetle-caused conifer mortality in forested areas thinned from 1985 to 1998 to similar, non-thinned areas and (2) identified site, stand and individual tree characteristics associated with conifer mortality. We sampled ponderosa pine (Pinus ponderosa var ponderosa Dougl. ex Laws.) and Jeffrey pine (Pinus jeffreyi Grev. and Balf.) trees in pre-commercially thinned and non-thinned plantations and ponderosa pine and white fir (Abies concolor var lowiana Gordon) in mixed conifer forests that were commercially thinned, salvage-thinned, and non-thinned. Clusters of five plots (1/50thha) and four transects (20.1A-100.6m) were sampled to estimate stand, site and tree mortality characteristics. A total of 20 pre-commercially thinned and 13 non-thinned plantation plot clusters as well as 20 commercially thinned, 20 salvage-thinned and 20 non-thinned mixed conifer plot clusters were established. Plantation and mixed conifer data were analyzed separately. In ponderosa pine plantations, mountain pine beetle (Dendroctonus ponderosae Hopkins) (MPB) caused greater density of mortality (treeshaa1 killed) in non-thinned (median 16.1treeshaa1) compared to the pre-commercially thinned (1.2treeshaa1) stands. Percent mortality (treeshaa1 killed/trees haa1 host available) was less in the pre-commercially thinned (median 0.5%) compared to the non-thinned (5.0%) plantation stands. In mixed conifer areas, fir engraver beetles (Scolytus ventralis LeConte) (FEN) caused greater density of white fir mortality in non-thinned (least square mean 44.5treeshaa1) compared to the commercially thinned (23.8treeshaa1) and salvage-thinned stands (16.4 trees haa1). Percent mortality did not differ between commercially thinned (least square mean 12.6%), salvage-thinned (11.0%), and non-thinned (13.1%) mixed conifer stands. Thus, FEN-caused mortality occurred in direct proportion to the density of available white fir. In plantations, density of MPB-caused mortality was associated with treatment and tree density of all species. In mixed conifer areas, density of FEN-caused mortality had a positive association with white fir density and a curvilinear association with elevation.

The rate at which nitrate decreased was greatest along waterways. Phosphorus contrasted nitrate, showing no temporal trend. Phosphorus greatest along waterways where groundwater could rise to become runoff. Along waterways, sediment accumulated due to past erosion is likely phosphorus source. One anticipated benefit of ecosystem restoration is water quality improvement. This study evaluated NO3-N and phosphorus in subsurface waters during prairie establishment following decades of row-crop agriculture. A prairie seeding in late 2003 became established in 2006. Wells and suction cup samplers were monitored for NO3-N and phosphorus. Nitrate-N varied with time and landscape position. Non-detectable NO3-N concentrations became modal along ephemeral drainageways in 2006, when average concentrations in uplands first became <10mg NO3-NL super(-1). This decline continued and upland groundwater averaged near 2mg NO3-NL super(-1) after 2007. The longer time lag in NO3-N response in uplands was attributed to greater quantities of leachable N in upland subsoils. Spatial differences in vadose-zone travel times were less important, considering water table dynamics. Phosphorus showed a contrasting landscape pattern, without any obvious temporal trend. Phosphorus was greatest along and near ephemeral drainageways. Sediment accumulation from upland agricultural erosion provided a source of P along drainageways, where shallow, reductive groundwater increased P solubility. Phosphorus exceeded eutrophication risk thresholds in these lower areas, where saturation-excess runoff could readily transport P to surface waters. Legacy impacts of past agricultural erosion and sedimentation may include soluble phosphorus in shallow groundwater, at sites prone to saturation-excess runoff.

Aflatoxin is a potent carcinogen, and its presence markedly reduces the value of grain. Understanding and enhancing host resistance to A. flavus infection and/or subsequent aflatoxin accumulation is generally considered an efficient means of reducing grain losses to aflatoxin. Different proteomic, genomic and genetic studies of maize (Zea mays L.) have generated large data sets with the goal of identifying genes responsible for conferring resistance to A. flavus, or aflatoxin. In order to maximize the usage of different data sets in new studies, including association mapping, we have constructed a relational database with web interface integrating the results of gene expression, proteomic (both gel-based and shotgun), Quantitative Trait Loci (QTL) genetic mapping studies, and sequence data from the literature to facilitate selection of candidate genes for continued investigation. The Corn Fungal Resistance Associated Sequences Database (CFRAS-DB) (http://agbase.msstate.edu/) was created with the main goal of identifying genes important to aflatoxin resistance. CFRAS-DB is implemented using MySQL as the relational database management system running on a Linux server, using an Apache web server, and Perl CGI scripts as the web interface. The database and the associated web-based interface allow researchers to examine many lines of evidence (e.g. microarray, proteomics, QTL studies, SNP data) to assess the potential role of a gene or group of genes in the response of different maize lines to A. flavus infection and subsequent production of aflatoxin by the fungus. CFRAS-DB provides the first opportunity to integrate data pertaining to the problem of A. flavus and aflatoxin resistance in maize in one resource and to support queries across different datasets. The web-based interface gives researchers different query options for mining the database across different types of experiments. The database is publically available at http://agbase.msstate.edu.

Cross-sectional design with a multi-ethnic (White, African-American, Hispanic, Other) sample of 813 children aged 9-10 years and 738 children aged 17-18 years. Children were recruited from local elementary and high schools with at least 30 % minority ethnic enrolment. Children's height, weight and waist circumference were measured along with their PROP taster status. PROP was measured using two paper discs, one impregnated with NaCl (1.0 mol/l) and the other with PROP solution (0.50 mmol/l). A significant PROP sensitivity by socio-economic status (SES) interaction term (P = 0.010) was detected wherein supertasters had the largest BMI percentile and Z-score, but only among the group with highest SES. The results suggest that other factors overwhelmed the influence of PROP sensitivity on adiposity in lower-SES groups. The percentage of variance accounted for by the interaction term was about 1 %. Thus, PROP supertasters had the largest BMI percentile and Z-score, but only among the highest-SES group.

Relative error of simulated mean, normalized objective function (root mean square error divided by the observed mean), and index of agreement evaluation statistics were calculated to compare modeled results to observed data. A one-way, fixed-effect ANOVA was also performed to determine differences among experimental locations and summit, sideslope, and toeslope landscape positions. GPFARM simulations matched observed data trends, with the model correctly distinguishing variations between the summit and toeslope landscape positions. In addition, experimental observations and GPFARM simulations both indicated that the toeslope landscape position was the most productive for grain yield and also exhibited higher amounts of crop residue, total soil profile water content, and total soil residual NO sub(3)-N. The GPFARM crop model performed adequately but was inconsistent in simulating winter wheat, corn, and sorghum dry mass grain yield. GPFARM performance in simulating crop residue was poorer than for crop grain yield. GPFARM predicted mean total soil profile water content was generally within +/-20% of the observed mean across locations and landscape positions, with the model somewhat biased towards overpredicting total soil profile water content at the summit and sideslope landscape positions. Total soil profile residual NO sub(3)-N was underpredicted by GPFARM across all locations and landscape positions by an average of 30%. Although GPFARM appears to have reasonably simulated long-term output responses across a landscape catena for the eastern Colorado experimental locations (especially given the simplifying assumptions in many of the GPFARM simulation components and the inherent variability present at the experimental plot level), different interpretations of GPFARM performance can be made depending on the evaluation statistic of interest. Furthermore, the model cannot fully account for water and chemical movement across the landscape catena; simulation results suggest that addition of a spatially-distributed routing component should offer improvements in GPFARM prediction accuracy across a catena where surface runoff or lateral subsurface flow is occurring.

In this research, we prepared and characterized rice and wheat batters with and without using beer to replace water in the formulation. We studied and provided data on the effect of beer on the frying properties of batter and its coated foods. RESULTS: With beer in the formulation, oil uptake of fried batters generally increased by up to 18%. Instrumental textural analyses indicate that beer-battering treatment generally decreased the hardness, increased the fracturability and improved the crispness of the fried batters. Sensory evaluations show similar trends, though to a lesser extent, that fish and onion rings coated with batters were softer but crispier with beer than without. CONCLUSION: In general, beer-battering caused an increase in the oil uptake of the batter during frying. It also made the texture of fried batters slightly softer and crispier. The effects are more pronounced for rice batters than wheat batters.

The utility of variable-rate (VR) lime application in the initial production year (plant cane) of a 3-year sugarcane crop cycle was investigated at three locations planted to the cultivar LCP 85-384 for a total of nine site-years. A conventional, uniform-rate (UR) lime application method was compared to a VR application method and a no-lime control. Prior to lime application, soil samples (0-200mm) were taken on a 0.4ha grid to produce VR application maps. Soil samples were also taken after each crop of the 3-year production cycle to determine effects of lime application on soil properties. The combined results showed that neither the UR nor VR lime application method consistently improved cane or sugar yields over the no-lime control. Cane and sugar yields at Naquin Farms (NF) were increased with both the UR and VR methods, with the UR method having a slight advantage. At St. Louis Plantation (SLP), only the VR method in the first-ratoon crop increased cane and sugar yields and there were no yield differences due to lime application at Ellendale Plantation (EP). At NF and SLP, application of lime in the plant-cane crop increased soil pH and available phosphorus over the 3-year production cycle. At EP, lime application did not influence any of the soil properties measured. The failure to get a yield response from lime application at SLP and EP may have been due to the fact that fertility levels at planting were already greater than those at NF and the nitrogen fertilizer rates used by the grower at EP were higher than those at either SLP or NF. This may have obscured any positive yield effects that would be realized from increased nutrient availability. It is also possible that multiple VR lime applications will be required over a number of crop cycles to stabilize soil pH levels before a consistent positive effect on cane and sugar yields is observed with VR application. This possibility will be investigated in future studies.

Its presence in grain greatly reduces its value and marketability. Aflatoxin accumulation is frequently associated with high temperatures, drought, and insect damage. Ten maize germplasm lines, some selected for resistance to aflatoxin accumulation, were crossed to transgenic (transformed with genes from Bacillus thuringiensis Berliner (BT) and expressing the Cry1Ab protein) and non-transgenic versions of LH287. Testcrosses were evaluated for ear damage from insect feeding and aflatoxin accumulation. Ear damage caused by insect feeding and aflatoxin accumulation was significantly less in BT than non-BT testcrosses. The germplasm line BT/non-BT interaction was not significant. Three lines selected for resistance to aflatoxin accumulation (Mp313E, Mp717, Mp04:97) exhibited the lowest levels of aflatoxin whether crossed to the BT or non-BT versions of LH287. Neither the levels of aflatoxin accumulation nor ear damage differed significantly between the BT and non-BT versions of these hybrids. This indicates that adding BT to hybrids produced from Mp313E, Mp717, or Mp04:97 would not be expected to increase resistance to aflatoxin accumulation.

Asian soybean rust has an unusually broad host range and infects by direct penetration through the leaf cuticle. In order to understand the early events in the infection process, it is important to identify and characterize proteins in P. pachyrhizi. Germination of the urediniospore is the first stage in the infection process and represents a critical life stage applicable to studies with this obligate pathogen. We have applied a 2-DE and MS approach to identify 117 proteins from the National Center of Biotechnology Information nonredundant protein database and a custom database of Basidiomycota EST sequences. Proteins with roles in primary metabolism, energy transduction, stress, cellular regulation and signaling were identified in this study.

Surveys were conducted for their occurrence in fire ant colonies across southern South America. In Argentina, 443 ant colonies were excavated at 57 sites and 11 positive sites were revisited to monitor the field persistence. In Paraguay, Bolivia and Uruguay, 288 colonies were examined in the field in 16 sites. Orasema simplex Heraty was the most abundant species, and found in 63.7% of the total parasitized colonies (n = 72). Orasema xanthopus (Cameron) and Orasema salebrosa Heraty were found at four sites in Argentina. In Bolivia, Orasema pireta Heraty was found at one site and parasitizing an unidentified Solenopsis species. Two new host species for Orasema were discovered, Solenopsis quinquecuspis Forel and Solenopsis macdonaghi Santschi. In addition, Orasema aenea Gahan was found parasitizing fire ants for the first time. The parasitoids persisted at 36.4% of the positive sites, most of them in rural habitats.

Tested doses of FFC were 0, 5, 10, 15, and 30 mg of active ingredient per kilogram of fish body weight (BW) per day. Fish were subjected to waterborne S. iniae exposure after skin scraping, and administration of medicated feed started at 6 h postchallenge and continued for 10 consecutive days, followed by a 12-d posttreatment observation period. Administration of FFC-medicated feed for 10 d significantly increased (P < 0.05) the survival of S. iniae-infected blue tilapia from 19% in the challenged, nonmedicated positive control group to 94, 96, 99, and 98% in the 5-, 10-, 15-, and 30-mg/kg FFC treatment groups, respectively. The survival rates of the different FFC-medicated treatment groups were not significantly different. At the conclusion of the experiment, no S. iniae carriers were detected in any challenged group receiving the FFC-medicated diet, while the bacterium was recovered from the S. iniae-challenged, nonmedicated survivors of the infection. This study suggests that using FFC at 10 mg/kg BW daily for 10 d is an effective treatment against S. iniae infection in blue tilapia.

AquaFrin (lauryl methyl pyrifrin), a product currently being evaluated for commercial use, belongs to a class of porphyrins that have been shown to be very effective as antibacterial agents. As a preliminary step to assess the potential use of AquaFrin as a therapeutant against ESC and columnaris, we used a rapid bioassay to evaluate AquaFrin for antibacterial activity against the Gram-negative bacterium Edwardsiella ictaluri (etiological agent of ESC), two genotypes of the Gram-negative bacterium Flavobacterium columnare (etiological agent of columnaris disease), and the representative Gram-positive bacterium Staphylococcus aureus (American Type Culture Collection 29213) for comparison. In addition, we performed a bioassay-directed evaluation of AquaFrin for selective toxicity toward the musty cyanobacterium Planktothrix perornata. AquaFrin was found to possess antibacterial activity toward all tested bacteria and yielded the following minimal inhibitory concentration results: 0.5 mg/L for F. columnare isolate ALM-00-173, 1.0 mg/L for F. columnare isolate BioMed, 0.1 mg/L for S. aureus, and 9.8 mg/L for E. ictaluri. The range of 96-h 50% inhibition concentrations (0.07-0.2 mg/L) for AquaFrin toward P. perornata and the green alga Selenastrum capricornutum indicates strong potential for its use as a broad-spectrum algicide.

Wildlife reservoirs of brucellosis include bison (Bison bison) and elk (Cervus elaphus nelsonii) for Brucella abortus whereas Brucella suis is the predominant species infecting feral swine. The persistence of brucellosis in wildlife reservoirs poses a risk for reintroduction of Brucella into domestic livestock. Reducing the prevalence of brucellosis in wildlife reservoirs is anticipated to be complicated and costly, and the problem is unlikely to be quickly resolved.

Therefore, we sought to determine the prevalence of T. gondii infection and associated characteristics in 61 plumbers, 203 construction workers, and 168 gardeners in Durango City, Mexico. Participants were tested for T. gondii IgG and IgM antibodies with the use of enzyme-linked immunoassays. In addition, sociodemographic, clinical, and behavioral characteristics from each participant were obtained. IgG T. gondii antibodies were found in 4 (6.6%) plumbers, 17 (8.4%) construction workers, and 10 (6.0%) gardeners; T. gondii IgM antibodies were found in 3 (1.5%) construction workers and 4 (2.4%) gardeners, but in none of the plumbers. In the total population, the prevalence of T. gondii infection was significantly higher in workers living in suburban areas, without education, workers that consumed chorizo, and those who suffered from any disease (P < 0.05). In gardeners, prevalence of infection was significantly higher in those with blood transfusion, and memory impairment (P < 0.05). Multivariate analysis showed that T. gondii infection was positively associated with consumption of unwashed fruits (adjusted odds ratio [OR] = 2.41; 95% confidence interval [CI]: 1.13-5.13), and with raising animals (adjusted OR = 2.53; 95% CI: 1.00-6.37). This is the first report of contributing factors for T. gondii infection in workers occupationally exposed to water, sewage, and soil in a Mexican city, and results will contribute to the design of optimal preventive measures.

Independent variables included percent cover, average height, and plant volume. We explored 2 ellipsoid volumes: one with maximum plant height and 2 crown diameters and another with live crown height and 2 crown diameters. Dependent variables were total, live, leaf, and dead biomass. Simple, multiple, linear, and power equations were investigated. Models were chosen based on scatter plots, residual plots, and R2 and SEE values. In general, simple power equations provided the best-fit regressions. For shrubs, the ellipsoid volume computed with maximum plant height best predicted total plant weight, and the ellipsoid volume computed with the live crown height best predicted shrub foliage weight. In addition to regression equations for biomass, ratios for division of that biomass into 1-, 10-, 100-, and 1000-hour fuels were derived for common large shrubs. Regression equations were also derived to relate litter mat sizes of major shrub species to litter weights. The equations in this paper could be used to predict biomass in other areas of the Great Basin if training data were taken to validate or adjust these models.

Structure-activity analysis revealed that antifungal activities of benzoic and gallic acids were increased by addition of a methyl, methoxyl or chloro group at position 4 of the aromatic ring, or by esterification of the carboxylic acid with an alkyl group, respectively. Thymol, a natural phenolic compound, was a potent chemosensitizing agent when co-applied with the antifungal azole drugs fluconazole and ketoconazole. The thymol-azole drug combination demonstrated complete inhibition of fungal growth at dosages far lower than the drugs alone. Co-application of thymol with amphotericin B had an additive effect on all strains of aspergilli tested with the exception of two of three strains of A. terreus, where there was an antagonistic effect. Use of two mitogen-activated protein kinase (MAPK) mutants of A. fumigatus, sakA and mpkC, having gene deletions in the oxidative stress response pathway, indicated antifungal and/or chemosensitization activity of the benzo analogues was by disruption of the oxidative stress response system. Results showed that both these genes play overlapping roles in the MAPK system in this fungus. The potential of safe, natural compounds or analogues to serve as chemosensitizing agents to enhance efficacy of commercial antifungal agents is discussed.

Sophorolipid production was tested for 26 strains representing 19 species of the Starmerella yeast clade, including Starmerella bombicola and Candida apicola, which were previously reported to produce sophorolipids. Five of the 19 species tested showed significant production of sophorolipids: S. bombicola, C. apicola, Candida riodocensis, Candida stellata and a new species, Candida sp. NRRL Y-27208. A high-throughput matrix-assisted laser desorption-ionization-time of flight MS assay was developed that showed S. bombicola and C. apicola to produce a lactone form of sophorolipid, whereas C. riodocensis, C. stellata and Candida sp. NRRL Y-27208 produced predominantly free acid sophorolipids. Phylogenetic analysis of sequences for the D1-D2 domains of the nuclear large subunit rRNA gene placed all sophorolipid-producing species in the S. bombicola subclade of the Starmerella clade.

The rates of VFA production increased over extended incubations (24 h), and hops extract caused an increase in the propionate to acetate ratio. Hops extract inhibited the growth and metabolism of Streptococcus bovis, but Selenomonas ruminantium and Megasphaera elsdenii were not affected. Likewise, the propionate production of M. elsdenii-S. bovis co-cultures, but not M. elsdenii-S. ruminantium co-cultures, was decreased in the presence of hops extract.Conclusions: These results are consistent with the hypothesis that the hops inhibit Gram-positive lactic acid bacteria (S. bovis), and the rumen microbial community requires a period of adaptation before normal VFA production resumes. Selenomonas bovis and S. ruminantium both produce lactate, which is the substrate for propionate production by M. elsdenii. However, S. ruminantium has an outer membrane, while S. bovis does not.Significance and Impact of Study: The enhanced production of the gluconeogenesis precursor, propionic acid, provides further evidence that plant secondary metabolites from hops could be used to improve rumen fermentation.

Females deposited similar-sized egg masses on all three plants. Hatching was highest with eggs deposited on euonymus and lowest for those deposited on sunflower. Embryonic development time among host plants was similar while nymph development time was shortest on sunflower and longest on euonymus. Nymph survival to adulthood ranged from 32% on euonymus to 82% for those reared on sunflower. Adult females had similar life spans on sunflower and chrysanthemum. H. vitripennis completed a lengthy egg-to-adult development on euonymus, however, mating did not occur. The onset of mating was contingent on maturation of adult females. The majority of mating activity occurred within the first three days after onset. Premating periods ranged from 6 to 7 d on sunflower to 27 d on chrysanthemum, with overall mating rates of 77.4 and 19.8%, respectively. Females typically mated more than once and they had the longest oviposition period and highest egg production on sunflower; approximately 50 and 67% of total number of eggs were deposited within first 45 d after the start of oviposition on sunflower and chrysanthemum, respectively. Adult size and weight related to which host plant was consumed throughout development. Greater intrinsic and finite rates of increase and net reproduction rate, and shorter population doubling time occurred when the sharpshooters were allowed to develop on sunflower. The overall developmental and reproductive parameters obtained in this study indicate that a mixed host plant system, composed of sunflower and euonymus or chrysanthemum plants, is an efficient means for optimizing egg production and colony maintenance of the glassy-winged sharpshooter.

We examined the effects of atmospheric CO2 concentration (ambient vs. 780p.p.m.) and soil moisture (15 vs. 20% m/m) on plant biomass and plant N uptake. Our objective was to separate CO2 effects not related to water from water-mediated CO2 effects by frequently watering the pots, thereby eliminating most of the elevated CO2 effects on soil moisture, and including a water treatment similar in magnitude to the water-savings effect of CO2. 3.Biomass of the C3 grasses Hesperostipa comata and Pascopyrum smithii increased under elevated CO2, biomass of the C4 grass Bouteloua gracilis increased with increased soil moisture, while biomass of the forbs Artemisia frigida and Linaria dalmatica had no or mixed responses. Increased plant N uptake contributed to the increase in plant biomass with increased soil moisture while the increase in plant biomass with CO2 enrichment was mostly a result of increased N use efficiency (NUE). Species-specific responses to elevated CO2 and increased soil moisture differed between monocultures and mixtures. Both under elevated CO2 and with increased soil moisture, certain species gained N in mixtures at the expense of species that lost N, but elevated CO2 led to a different set of winners and losers than did increased water. 4.Elevated CO2 can directly increase plant productivity of semi-arid grasslands through increased NUE, while a CO2-induced increase in soil moisture stimulating net N mineralization could further enhance plant productivity through increased N uptake. Our results further indicate that the largest positive and negative effects of elevated CO2 and increased soil moisture on plant productivity occur with interspecific competition. Responses of this grassland community to elevated CO2 and water may be both contingent upon and accentuated by competition.

Germination temperature profiles were developed for diffuse knapweed seeds collected from sites in the Great Basin and Colorado. Each profile consisted of seeds germinated at 55 constant or alternating temperatures from 0 through 40C. The resulting germination was used to develop quadratic response surfaces with regression analysis. Some germination occurred from 71 to 96% of the temperature regimes, depending on the accession being tested. Maximum observed germination ranged from 85 to 98%. Optimum germination, defined as the maximum observed minus one half the confidence interval at the 0.01 level of probability, occurred at a wide range of temperatures from cold periods of 0 through 20C, alternating with warm periods of 10 through 35C. The temperature regimes that most frequently supported optimum germination were 5/25C (5C for 16h and 25C for 8h in each 24-h period) and 10/25C. Germination of diffuse knapweed seeds was generally higher at alternating than constant temperatures.

The calculated soil binding constants for both herbicides varied between the two techniques, but the centrifugation assay had a lower coefficient of variation compared to the batch-slurry assay. These results indicate that a centrifugation assay is a more accurate procedure for measuring the interaction of aminopyralid and clopyralid with soils. Aminopyralid adsorbed more tightly than clopyralid to six of the eight soils tested. Adsorption Kd values ranged from 0.083 to 0.364 for clopyralid and 0.106 to 0.697 for aminopyralid. Pearson correlation analysis indicated that binding of both herbicides was highly correlated to soil organic matter and texture but not to soil pH. On average, soil thin-layer chromatography indicated that aminopyralid was less mobile (Rf = 0.82) than clopyralid (Rf = 0.91), although both were mobile. These results suggest that aminopyralid will have a lower leaching potential than clopyralid. Lower potential aminopyralid soil leaching, coupled with low use rates, suggests it may be the herbicide of choice in areas where potential for leaching could be a concern.

Twenty-three isolates of Trichoderma were screened for suppression of a mixture of 4 genetically distinct isolates of this pathogen on bell pepper (Capsicum anuum) in greenhouse pot assays. Of these 23 isolates, GL12, GL13, and Th23 provided significant suppression of P. capsici in at least 2 assays. These isolates were then compared with Trichoderma virens isolates GL3 and GL21 for suppression of this disease in the presence and absence of the harpin-based natural product Messenger. Isolates GL3 and Th23 provided significant disease suppression (P less than or equal to 0.05) in 3 of 4 assays, while GL12, GL13, and GL21 provided significant suppression in 2 of 4 assays. There was no apparent benefit from the application of Messenger. Phylogenetic analysis of these 5 isolates (based on the ITS1 region of the nuclear rDNA cluster and tef1), and an additional 9 isolates that suppressed P. capsici in at least 1 assay, separated isolates into 2 clades, with 1 clade containing GL3, GL12, GL13, and GL21. There were also 2 more distantly related isolates, one of which was Th23. We report here the identification of genetically distinct Trichoderma isolates for potential use in disease management strategies employing isolate combinations directed at suppression of P. capsici on pepper.Original Abstract: Des mesures de controle compatibles avec l'environnement sont requises pour enrayer la contamination du poivron par Phytophthora capsici.

Despite the implications of resprays on the spread of herbicide-resistant weeds, respray frequencies and causal factors are poorly understood. A two-part survey of glyphosate-resistant soybean fields and custom application services was conducted in Illinois during 2005 and 2006 to determine the relative frequency of respray requests for postemergence glyphosate, and to identify weed community factors associated with glyphosate respray requests. A meta-analysis was then utilized to project the impacts of weed community factors driving respray requests on crop yield. Glyphosate resprays were requested for 14% of surveyed fields in both 2005 (n = 43) and 2006 (n = 90). In 2005, respray requests were highly associated with both population densities of weed communities visible from roadsides and incidences of skips (i.e., rectangular areas of escaped weeds indicating custom application failure). A skip increased the odds of respray request by more than ninefold, and population densities of weed communities visible from roadsides were, on average, 2.5 times greater in respray-requested fields compared with nonrequested fields. In 2006, respray requests were associated with population densities of weed communities identified by walking through fields. Contrary to 2005, requests in 2006 were concentrated in those fields with low weed population densities. Prior to resprays, weed communities capable of causing substantial soybean yield loss were present in both respray-requested and nonrequested fields in 2005 but in only nonrequested fields in 2006. Although this investigation indicated that custom applicators can take actions to reduce respray requests (i.e., avoiding skips), farmers and custom applicators should be prepared to implement additional weed control after postemergence glyphosate applications because damaging weed communities may remain.

These insects may cause damage to plants by direct feeding and/or vectoring plant pathogens. Psyllid-transmitted bacterial diseases are increasingly becoming important in perennial and annual crops. Several reports have shown that the fastidious bacterium 'Candidatus Liberibacter', vectored by at least four psyllid species, is associated with newly-emerging and economically important diseases of crops, including Huanglongbing or citrus greening disease in Citrus spp. and zebra chip in potatoes, Solanum tuberosum L. Huanglongbing is vectored by the Asian citrus psyllid, Diaphorina citri Kumayama, and the African citrus psyllid, Trioza erytreae Del Guercio, whereas zebra chip is vectored by the potato/tomato psyllid, Bactericera cockerelli Sulc Recently, 'Ca. Liberibacter' has been associated for the first time with the carrot psyllid, Trioza apicalis Foerster, and carrot, Daucus carota L. subsp. sativus, plants affected by this insect in northern Europe. An overview of psyllid species vectoring bacterial diseases to annual crops, with emphasis on potato psyllid and carrot psyllid, is presented herein.

The pink bollworm, Pectinophora gossypiella (Saunders) (Lepidoptera: Gelechiidae), is currently the target of an area-wide eradication program with the purpose to eliminate pink bollworm from cotton-producing areas of the U.S. and adjacent areas of northern Mexico. Transgenic Bt cotton is a key component of the program. Evolution of resistance to Bt cotton could jeopardize the eradication program and diminish success of long-term control of pink bollworm populations. Molecular monitoring for known resistance alleles and bioassays indicated that pink bollworm resistance to Bt cotton in the U.S. remains rare. However, recent discovery of field-evolved resistance to Bt cotton in India emphasizes the need for diligent resistance monitoring and stewardship of the Bt transgenic technology. Resistance to Cry1Ac in laboratory-selected strains of pink bollworm may involve at least two resistance mechanisms, based on characterization of cadherin-based resistant strains and a newly selected Bt4R strain. In all previous resistant strains of pink bollworm, resistance involved mutations in a cadherin gene encoding for a functional Cry1Ac toxin receptor. Selection of the Bt4R strain using Bt cotton bolls and Cry1Ac in diet revealed a novel mechanism of resistance that differs from previously described Cadherin mutations.

We analyze data from the Current Population Survey Food Security Supplement to find reasons for this seeming anomaly. Analysis of a 2-year panel sample of households interviewed in 2 successive years found different conditions in 2 distinct groups. One third of households that left SNAP in one year returned in the following year and were more likely to have had very low food security in both years. Households that left SNAP in 1 year and remained off through the following year were also more likely than current recipients to have had very low food security in the first year, but by the end of the following year, the prevalence of very low food security was lower than among those still on the program. Logistic regression analysis indicates that, for households with very low food security, leaving SNAP was strongly associated with higher income and full-time employment, suggesting that most such households left SNAP because their income had increased so that they were no longer eligible.

This paper examines the sufficiency of rail freight competition and the effects of intramodal competition on rail rates. The paper begins with a review of the importance of rail transportation for U.S. agricultural producers. Specific attention is paid to the nature of competition faced by railroads, especially since deregulation, using the analytical tool of inverse Herfindahl-Hirschman Indices (HHI), by USDA Crop Reporting Districts (CRD). As shown by the inverse HHIs, the overall level of rail competition for grains and oilseeds has generally decreased since the 1985-1992 period, even though rail competition has increased for some CRDs. In addition, revenue to variable cost ratios (R/VC) increased in most of the CRDs analyzed, and the analysis found them related to the number of railroads competing in the CRD. Competition is then analyzed relative to the revenue per ton, revenue per ton-mile, and the revenue to variable cost ratios (R/VC) associated with the level of competition for six states with the least rail-to-rail competition, and distant from water transportation, with those for four states having more rail-to-rail competition and close proximity to water transportation.

Embryonic development determines the life cycle of many species of grasshoppers, which, in cold climates, spend two winters in the egg stage. Increasing temperatures associated with climate change in the subarctic could potentiate a switch to a univoltine life cycle. However, egg hatch could be delayed by maintaining a closed vegetative canopy, which would lower soil temperatures by shading the soil surface. Prediapause and postdiapause embryonic developmental rates were measured in the laboratory over a wide range of temperatures for Melanoplus borealis Fieber and Melanoplus sanguinipes F. (Orthoptera: Acrididae) A model was fit to the data and used to predict dates of egg hatch in the spring and prediapause development in the fall under different temperature regimens. Actual soil temperatures were recorded at several locations over 5 yr. To simulate climate warming, 2, 3, or 4 degree C was added to each hourly recorded temperature. Results suggest that a 2, 3, or 4 degree C increase in soil temperatures will result in eggs hatching approximately 3, 5, or 7 d earlier, respectively. An increase of 3 degree C would be required to advance prediapause development enough to allow for a portion of the population to be univoltine in warmer years. To simulate shading, 2 and 4 degree C were subtracted from observed temperatures. A 4 degree C decrease in temperatures could potentially delay hatch by 8 d.

Thus, the possible application of grazing and fire as components of an ecologically based grasshopper management strategy must be investigated in regional studies. In this study, we examined the effects of grazing and fire on grasshopper population density and community composition in a northern Great Plains mixed-grass prairie. We employed a large-scale, replicated, and fully-factorial manipulative experimental design across 4 yr to examine the separate and interactive effects of three grazing systems in burned and unburned habitats. Grasshopper densities were low throughout the 4-yr study and 1 yr of pretreatment sampling. There was a significant fire by grazing interaction effect on cumulative density and community composition, resulting from burned season long grazing pastures having higher densities than unburned pastures. Shannon diversity and grasshopper species richness were significantly higher with twice-over rotational livestock grazing. The ability to draw strong conclusions regarding the nature of species composition shifts and population changes in the presence of fire and grazing is complicated by the large site differences and low grasshopper densities. The results reinforce the importance of long-term research to examine the effects of habitat manipulation on grasshopper population dynamics.

E. Smith); and cabbage looper, Trichoplusia ni (Huebner); in a laboratory. Fifty leaves from the middle of the plants were collected every 20 days, starting at 40 days and until 120 days after cottons were planted. The leaves were fed to 15 first-instar larvae of each insect pest until they died or pupated. Most larvae died when fed Bollgard II or WideStrike. At the end of the season (100-120 days after planting), more larvae died when fed Bollgard II than WideStrike. Conclusions from the results are that (1) mortality was not significantly different when the larvae were fed dual Bt cotton leaves of different ages; (2) survival duration depended on consumption of the amount of endotoxin that caused larval mortality; (3) biological characteristics of surviving lepidopterans (pupal weight, emergence, and developmental time) were significantly better on non-Bt cotton.

Serious epidemics of purple top disease of potato, caused by phytoplasma infections, have occurred in North and Central America and Central and Eastern Europe. Countries severely affected by phytoplasma diseases of potato include the United States, Mexico, Guatemala, Russia, and Romania. These emerging potato diseases are causing significant yield losses and a reduction in tuber and seed quality. Accurate identification of phytoplasmas involved in the disease and their insect vectors, in addition to a better understanding of disease epidemiology and vector population dynamics, are essential to effective management of phytoplasma diseases in potatoes. A case study of identification, epidemiology, and management of leafhopper-transmitted phytoplasma disease of potatoes in the Pacific Northwest of the United States is presented herein.

Thus, quantitative assessments of different phenolic compounds in Texas olive versus foreign oils were performed using modern analytical techniques. Samples of commercial and laboratory extracted Texas olive oils were compared with sample from 11 foreign oils. Total polyphenols in each oil sample were measured by the Folin-Ciocalteau method. Individual polyphenols were separated by high performance liquid chromatography and identified by comparing retention time and UV spectra with known compounds. Free acidity and the UV absorption were measured by standard AOCS (American Oil Chemists Society) methods. The Texas olive oil contained 27% higher amounts of total phenols than the highest amount of a foreign oil sample. Similarly, Texas olive oil also contained higher amounts of oleuropein, hydroxytyrosol, and pinoresinol compared to all other oils tested. Thus, olive oil pressed from olives harvested in hot summer days will be very competitive with other oils with regard to polyphenols contents and hence its health benefits. The free acidity in the commercial Texas oil was 0.35%, based on oleic acid, and its coefficient at K sub(268) UV absorption was <0.166. These numbers affirm that the Texas olive is "Extra Virgin".

Increasing methanol concentrations had little effect on the growth of the organism resulting in average cell dry weights (CDW; after SL separation) of 20.8c0.7g/l between 0 and 1.5% methanol. However, increasing methanol concentrations decreased SL production by 56% (from 12.7 to 5.6g/l at 1.5% methanol) which translated to SL yields on a cellular basis of between 0.60g SL/g cells (in the absence of methanol) to 0.27g SL/g cells (in the presence of 1.5% methanol). LC/MS revealed that increased methanol concentrations also resulted in larger concentrations (up to 20mol%) of free acid SLs but had little effect on the ratios of diacetylated SL lactones synthesized with palmitic acid (4mol%), linoleic acid (3mol%), oleic acid (80mol%), and stearic acid (13mol%) as the hydrophobic moieties.

The bacterium is spread locally and regionally by the citrus psyllid Diaphorina citri, and also can be disseminated by propagation of contaminated scion budwood that is grafted to the appropriate rootstock. The planting of 'Ca. Liberibacter asiaticus'-free trees is a component of a comprehensive strategy to manage huanglongbing. In contrast to the scion budwood, the rootstocks used to produce these trees are grown from seed. This research was undertaken to provide evidence as to whether or not 'Ca. L. asiaticus' can be transmitted through seed. Two groups of 360 or more seedlings each of various citrus species were grown from seed removed from fruit on trees that were symptomatic for huanglongbing and confirmed to be infected with 'Ca. L. asiaticus' by polymerase chain reaction (PCR) tests. These seedlings were tested multiple times over periods of up to 3 years. No symptoms typical of huanglongbing, such as blotchy leaf mottle, chlorotic shoots, or dieback of branches, were observed in these seedlings, and none of these 723 seedlings tested positive for the presence of 'Ca. L. asiaticus' even after repeated testing by sensitive quantitative PCR assays. Some sour orange seedlings did have quite pronounced and atypical growth, including stunting and mild to severe leaf malformation. These atypical growth habits were limited to seedlings that arose from zygotic embryos as determined by expressed-sequence tag simple-sequence repeat analyses. Thus, no evidence of transmission of 'Ca. L. asiaticus' via seed was obtained, and an earlier report of transmission of the pathogen through seed was not confirmed.

Commercial watermelon 'Fiesta' (diploid seeded) and Tri-X 313' (triploid seedless) scions were grafted onto the rootstocks in 2007 and 2008, respectively. In 2007, the plants grafted on rootstock from the wild watermelon germplasm line RKVL 318 had significantly less (P < 0.05) root galling than nongrafted 'Fiesta' watermelon or plants with the squash hybrid or bottle gourd rootstocks. In 2008, 'Fiesta' plants with rootstocks from all five wild watermelon germplasm lines and the commercial watermelon rootstock had significantly less (P < 0.05) root galling than plants with the squash hybrid or bottle gourd rootstocks. Root galling of the squash hybrid and bottle gourd rootstocks was severe (78 to 99%) in both years. Root galling for non-grafted 'Fiesta' and 'Tri-X 313' watermelon was 36 and 50%, respectively. Root galling for the wild watermelon germplasm lines ranged from 11 to 34% and 36 to 44% in 2007 and 2008, respectively. Wild watermelon germplasm lines derived from C. lanatus var. citroides were identified that may be useful as resistant rootstocks for managing root-knot nematodes in watermelon.

Gypsum application was included due to its widespread use on peanut (Arachis hypogaea). Both agricultural grade gypsum and reagent CaSO4-2H2O were tested. A laboratory soil incubation was conducted to evaluate interactive effects. Results indicated 1.5X greater metolachlor half-life (DT50) in soil amended with chlorothalonil (37 d) as compared to control soil (25 d). The two gypsum sources alone increased metolachlor DT50 to about 32 d and with the combination of chlorothalonil and gypsum, DT50 was 50 d, 2-fold greater than the control. Chlorothalonil dissipation was rapid (DT50 < 4d). A possible explanation for metolachlor dissipation kinetics is a build-up of the chlorothalonil intermediate (4-hydroxychlorothalonil) which limited soil microbial activity and depleted glutathione S-transferase (GST) from chlorothalonil detoxification. Further information related to gypsum impacts is needed. Results confirm previous reports of chlorothalonil impeding metolachlor dissipation and showed the gypsum application extended persistence even longer. Farming practices, such as reducing metolachlor application rates, may need to be adjusted for peanut cropping systems where chlorothalonil and gypsum are used.

Recently, variants of Y. ruckeri have been identified that lack flagella and associated motility. These strains are classified as biotype 2 (BT2) Y. ruckeri and these are considered an emerging problem in salmonid aquaculture. Little is known about the salmonid immune response to these variants. Herein, we report temporal and quantitative changes in rainbow trout immune response parameters following a primary challenge with BT2 Y. ruckeri strain YRNC10. Fish were injection-challenged with ten-fold dilutions of viable bacteria and sampled on days 1, 3, 5 and 7 post-challenge. TNFa1 and IL1-b1 transcripts were increased by day 1 post-challenge, and on days 3, 5 and 7 maximal gene transcript up-regulation occurred at a threshold of 64-256CFU per mg spleen tissue. Infection induced robust SAA gene up-regulation that was significantly correlated with increased gene expression of IL-1b1 (r =0.81, P <0.0001) and TNFa1 (r =0.55, P <0.0001). Y. ruckeri infection induced modest changes in INFI super(3) and Mx-1 gene transcript abundance at intermediate or high challenge doses and the expression patterns of both genes were positively correlated with pro-inflammatory gene and acute-phase gene transcription patterns. TNF superfamily 13b (BAFF) gene expression was significantly down-regulated in response to infection on days 3, 5 and 7 at the highest challenge doses. The spleen somatic index was significantly increased on days 3, 5 and 7 post-infection and positively correlated with spleen colony forming units and abundance of gene transcripts SAA, TNFa1, and IL1-b1. In summary, rainbow trout had a strong innate response following challenge with BT2 Y. ruckeri strain YRNC10 indicating that flagellin expression is not required for production of a robust pro-inflammatory and acute-phase gene transcription response. This study further supports the use of SAA transcript abundance and spleen somatic index as general measures of immunological status and fish health.

Urbanization, detachment from nature, and demographic changes are fostering discussions about strengthening the social and cultural dimensions of management. The complexities and subtleties of incorporating PPAs into existing government and societal contexts are explored with a focus on institutional and governance principles and an emerging paradigm that might deal with some conflicts. We present two examples, in their respective institutional contexts, that illustrate different ways to address one PPA aspect, recreation management. One example, from the Black Forest of southern Germany, has management principles that were developed jointly by public and agency representatives. Notable among the principles were shifts in management objectives, permanent participative planning approaches, and the assessment of institutional fit. A second example, from California, addressed recreation in a typical forestwide plan. People were engaged through public comment on, and reactions to, proposed directions prepared by forest staff. Specific recreation conflict potentials were left to emerge in later, more specific programmatic plans. The examples show how the suggested new governance principles are addressed in practice and how they might contribute to a better scientific understanding of the social functions of recreation. The challenges of moving from existing planning models to this new paradigm are also recognized. Adapted from the source document.

AN - 762468893; 20607619 AB - The PICM-19 pig liver stem cell line is a bipotent cell line, i.e., capable of forming either bile ductules or hepatocyte monolayers in vitro, that was derived from the primary culture of pig embryonic stem cells. The cell line has been strictly feeder-dependent in that cell replication, morphology, and function were lost if the cells were cultured without STO feeder cells. A method for the feeder-independent continuous culture of PICM-19 cells (FI-PICM-19) is presented. PICM-19 cells were maintained and grown without feeder cells on collagen I-coated tissue culture plastic for 26 passages (P26) with initial split ratios of 1:3 that diminished to split ratios of less than 1:2 after passage 16. Once plated, the FI-PICM-19 cells were overlaid with a 1:12 to 1:50 dilution of Matrigel or related extracellular matrix product. Growth of the cells was stimulated by daily refeedings with STO feeder-cell conditioned medium. The FI-PICM-19 cells grew to an approximate confluence of 50% prior to each passage at 2-wk intervals. Growth curve analysis showed their average cell number doubling time to be ~96 h. Morphologically, the feeder-independent cells closely resembled PICM-19 cells grown on feeder cells, and biliary canalicui were present at cell-to-cell junctions. However, no spontaneous multicellular ductules formed in the monolayers of FI-PICM-19 cells. Ultrastructural subcellular features of the FI-PICM-19 cells were similar to those of PICM-19 cells cultured on feeder cells. The FI-PICM-19 cells produced a spectrum of serum proteins and expressed many liver/hepatocyte-specific genes. Importantly, cytochrome P450 (EROD) activity, ammonia clearance, and urea production were maintained by the feeder-independent cells. This simple method for the propagation of the PICM-19 cell line without feeder cells should simplify the generation and selection of functional mutants within the population and enhances the cell line's potential for use in toxicological/pharmacological screening assays and for use in an artificial liver device.

Our objective was to determine if dry bean landrace G122, which lacks the Bct gene for resistance to CTV, contains novel resistance to the virus. Two populations, GT-A and GT-B, consisting of 98 F sub(5:7) recombinant inbred lines (RILs) in total were derived from a cross between G122 and the susceptible variety Taylor Horticultural and evaluated for phenotypic response to natural CTV field infection. Genetic analyses revealed random amplified polymorphism DNA (RAPD) markers associated with a major-effect quantitative trait loci (QTL) from G122 which exhibited stable expression across 3 years in both populations. Phenotypic variation explained by the QTL in GT-A (37.6%) was greater than in GT-B (20.4%). RAPD marker Q14.973 was converted to a sequence-characterized amplified region (SCAR) and designated SQ 14.973. The SCAR was used to locate the QTL on linkage group 6 of the Phaseolus core map. A survey of 74 common bean cultivars and breeding lines revealed SQ14.973 would be widely useful for marker-assisted selection of the QTL. An additional minor-effect QTL from G122 was detected on linkage group 7. G122 was determined to possess novel resistance to CTV conditioned by at least two genes, one with major the other minor effect.

To improve predictability of inoculum available for infection of ecologically and commercially important white pines, this research was conducted to identify the factors that influence the development and persistence of uredinia and telia on Ribes in their natural habitats. Numbers of infectious C. ribicola rust lesions (with potentially sporulating rust sori) on tagged Ribes missouriense plants in the woods fluctuated during the season. Changes in numbers of infectious rust lesions were related to rain that occurred 13 days earlier. In field experiments, supplemental leaf wetness provided for 2 days on Ribes shoots resulted in the development of rust lesions more frequently than on control shoots. Viable inoculum and susceptible hosts were present, and the environment was the limiting factor for disease development. Lesion necrosis and leaf abscission contributed to decreases in numbers of infectious rust lesions. Higher lesion density was significantly related to earlier leaf abscission. Telial fruiting bodies occurred in low numbers from early June throughout the remainder of the season.

Recent studies focus heavily on large conjugative plasmids, and the role that small plasmids play in resistance gene transfer is largely unknown. To expand our previous studies in assessing the prevalence of the isolates harboring ColE1-like plasmids carrying the aph gene responsible for kanamycin resistance (Kanr) phenotypes, 102 Kanr Salmonella isolates collected through the National Antimicrobial Resistance Monitoring System (NARMS) in 2005 were screened by PCR using ColE1 primer sets. Thirty isolates were found to be positive for ColE1-like replicon. Plasmids from 23 isolates were able to propagate in Escherichia coli and were subjected to further characterization. Restriction mapping revealed three major plasmid groups found in three or more isolates, with each group consisting of two to three subtypes. The aph genes from the Kanr Salmonella isolates were amplified by PCR, sequenced, and showed four different aph(3')-I genes. The distribution of the ColE1 plasmid groups in association with the aph gene, Salmonella serovar, and isolate source demonstrated a strong linkage of the plasmid with S. enterica serovar Typhimurium DT104. Due to their high copy number and mobility, the ColE1-like plasmids may play a critical role in transmission of antibiotic resistance genes among enteric pathogens, and these findings warrant a close monitoring of this plasmid incompatibility group.

Propiconazole was infused into mature oaks in July 2004 and roots were inoculated with pathogen endoconidia 1.0 m from injection sites at c2 weeks of fungicide treatment. Pathogen presence in wood samples was determined by isolation and fungicide concentrations measured using gas chromatography-mass spectrometry. Propiconazole was detected in the roots (,1.0 m from injection sites) of all treated trees at 2, 12, and 24 months. Propiconazole was detected in all samples (n = 68) at 2 and 12 months and in 93% of samples (n = 72) at 24 months with concentrations ranging from 815 ppm (12 months in lower stem) to 0.7 ppm (24 months in most distal root segment). Although pathogen isolation incidence was lower in treated than disease control trees at 2 and 12 months, at no time did an infused oak fail to yield the fungus upon isolation. The results document basipetal movement and degradation of propiconazole, as well as the survival of the pathogen, over time in roots and lower stems of infused red oaks.

Nearest percent estimates (NPEs) of disease severity were compared with Horsfall-Barratt (H-B) scale data to explore whether there was an effect of assessment method on hypothesis testing. A simulation model based on field-collected data using leaves with disease severity of 0 to 60% was used; the relationship between NPEs and actual severity was linear, a hyperbolic function described the relationship between the standard deviation of the rater mean NPE and actual disease, and a lognormal distribution was assumed to describe the frequency of NPEs of specific actual disease severities by raters. Results of the simulation showed standard deviations of mean NPEs were consistently similar to the original rater standard deviation from the field-collected data; however, the standard deviations of the H-B scale data deviated from that of the original rater standard deviation, particularly at 20 to 50% severity, over which H-B scale grade intervals are widest; thus, it is over this range that differences in hypothesis testing are most likely to occur. To explore this, two normally distributed, hypothetical severity populations were compared using a t test with NPEs and H-B midpoint data. NPE data had a higher probability to reject the null hypothesis (H sub(0)) when H sub(0) was false but greater sample size increased the probability to reject H sub(0) for both methods, with the H-B scale data requiring up to a 50% greater sample size to attain the same probability to reject the H sub(0) as NPEs when H sub(0) was false. The increase in sample size resolves the increased sample variance caused by inaccurate individual estimates due to H-B scale midpoint scaling. As expected, various population characteristics influenced the probability to reject H sub(0), including the difference between the two severity distribution means, their variability, and the ability of the raters. Inaccurate raters showed a similar probability to reject H sub(0) when H sub(0) was false using either assessment method but average and accurate raters had a greater probability to reject H sub(0) when H sub(0) was false using NPEs compared with H-B scale data. Accurate raters had, on average, better resolving power for estimating disease compared with that offered by the H-B scale and, therefore, the resulting sample variability was more representative of the population when sample size was limiting. Thus, there are various circumstances under which H-B scale data has a greater risk of failing to reject H sub(0) when H sub(0) is false (a type II error) compared with NPEs.

Elevated concentrations of the pollutants were determined with seasonal means for individual sites ranging between 62 and 88 ppb for O3, 1.0-3.8kg super(-'3) for HNO3, and 2.6-5.2kg super(-3) for NH3. Calculated O3 exposure indices were very high, reaching SUM00-191ppm, SUM60-151ppm, and W126-124ppm. Calculated nitrogen (N) dry deposition ranged from 1.4 to 15kgN super(-1) for maximum values, and 0.4-8kgN super(-1) for minimum values; potentially exceeding Critical Loads (CL) for nutritional N. The U.S., California, and European 8aah O3 human health standards were exceeded during 104, 108, and 114 days respectively, indicating high risk to humans from ambient O3. Ozone concentrations remained unchanged while those of nitric acid vapor and ammonia decreased along the river drainage crossing the Sierra Nevada Mountains.

However, desert grasslands of the southwestern United States often lack needed herbaceous fuel loads for effective prescriptions, dominant perennial graminoids may have poor fire tolerance, and some systems contain fire-tolerant invasive species. We examined long-term vegetation responses of a black grama (Bouteloua eriopoda Torr.) grassland that had been invaded by honey mesquite (Prosopis glandulosa) following a single prescribed burn. Vegetation responses to a 1995 prescribed burn were evaluated in a replicated randomized complete block design with a 2A-2 factorial treatment structure. Treatments were prescribed burning and livestock exclusion for both a grassland-dominated and a shrub-encroached grassland state within a complex of sandy and shallow sandy ecological sites. Vegetation responses were measured in 2008, 13 years after the burn treatment application. Neither black grama basal cover nor honey mesquite canopy cover were responsive (p <0.05) to any treatment. A single prescribed burn would be ineffective as a shrub control practice in this environment. Repeated but infrequent prescribed burning within shrub-encroached vegetative states, when used in combination with managed grazing, may be the management required for a transition to desert grassland states within these ecological sites.

AN - 759309230; 13217436 AB - The introduction of non-native species has accelerated due to increasing levels of global trade and travel, threatening the composition and function of ecosystems. Upon arrival and successful establishment, biological invaders begin to spread and often do so with considerable assistance from humans. Recreational areas can be especially prone to the problem of accidental non-native species transport given the number of visitors that arrive from geographically diverse areas. In this paper, we examine camping permit data to the Apostle Islands National Lakeshore in northwestern Wisconsin, USA, from 1999 to 2007 relative to gypsy moth distribution, phenology and outbreak data. During this time, gypsy moth populations became established in this area ahead of the moving population front of the gypsy moth, suggesting anthropogenic introduction. The permit data revealed that the majority of visitors arrived from outside of the gypsy moth established area. However, there was a consistent yearly trend of visitors that arrived from areas of high gypsy moth populations and who arrived during the gypsy moth life stage (egg masses) most likely to be successfully introduced. Using available data on the gypsy moth and its relationship to camping permit data, we describe how recreational managers could optimize park strategies to mitigate unwanted introductions of the gypsy moth as well as develop analogous strategies for managing other biological invaders in recreational areas.

This need is particularly acute among low-income individuals. This study examines the cost-effectiveness of two economic policies that use alternative policy levers available within the Supplemental Nutrition Assistance Program (formerly Food Stamp Program) to increase consumption of these under-consumed foods. Data from three nationally representative surveys are used to estimate demand elasticities, marginal propensity to spend on food out of food stamp benefits, and consumption amount of and spending on under-consumed foods among food stamp recipients. Results suggest that a 10% price subsidy would curtail consumption deficiencies by 4%-7% at an estimated cost of $734 million a year. When the same $734 million is used to finance food stamp benefits, consumption deficiencies are predicted to narrow by only 0.35%-0.40%. (JEL C34, D12, Q18). Adapted from the source document.

These carbonates have various commercial uses in cosmetic, fuel additive, and lubricant applications. Oleochemical carbonates have not been examined for their applicability as phase change materials (PCM). The latent heats of melting and freezing for a series of symmetrical oleochemical carbonates ranging from 21-37 carbon atoms were evaluated to develop a fundamental understanding of the solid-liquid transitions for utilization in thermal energy storage (TES) applications. The phase transitions and associated thermal properties were determined by differential scanning calorimetry (DSC) and thermal gravimetric analysis (TGA). Decyl, dodecyl, tetradecyl, hexadecyl, and octadecyl carbonates had peak melting and freezing points of -2.2, 19.3, 33.7, 44.9, and 51.6 and -6.3, 14.3, 28.7, 40.3, and 46.9 C, respectively. In general, these carbonates exhibited sharp phase transitions and good latent heat properties. The latent heats of melting and freezing for decyl, dodecyl, tetradecyl, hexadecyl, and octadecyl carbonates were 144, 200, 227, 219, and 223 and 146, 199, 229, 215, and 215 J/g, respectively. These carbonates represent novel renewable-based PCM chemicals that compliment fatty acids, fatty alcohols, and their fatty acid esters while providing a potentially valuable biobased alternative to paraffin wax and salt hydrate PCM currently dominating the PCM market.

Using the t(4; 11) ALL line SEM, we evaluated chemotherapy resistance in NOD.CB17-Prkdcscid/J mice. SEM cells were injected into the tail vein and engraftment was monitored by flow cytometry. Once engraftment was observed, mice were injected intraperitoneally with phosphate-buffered saline (PBS), or vincristine (0.5 mg/kg body weight) three times per week for 4 weeks (n = 8 per group). The level of P-glycoprotein in SEM cells was increased 3-fold by vincristine treatment compared to PBS-treated mice. Survival curves showed that leukemia cell growth was initially delayed by vincristine treatment, but the mice eventually succumbed to disease. These data describe a novel inducible model for investigating multi-drug resistance mechanisms in high-risk t(4; 11) ALL.

Fungal isolate Coniochaeta ligniaria was inoculated into the hydrolysates to metabolize and remove inhibitory compounds prior to yeast fermentation of glucose. Switchgrass, reed canarygrass, and alfalfa stem samples were pretreated with dilute acid at 10% w/w biomass loading and subjected to bioabatement with strain NRRL30616, to prepare the material for simultaneous saccharification of cellulose and fermentation by Saccharomyces cerevisiae. Bioabatement eliminated the extended fermentation lag times associated with inhibitory compounds and observed for the unconditioned biomass hydrolysates controls. Bioabatement was as effective as lime conditioning at reducing fermentation lag times. Prolonged incubations with the bioabatement microbe resulted in consumption of some glucose and reduced production of ethanol.

AN - 748968249; 20599947 AB - The mechanism by which zinc regulates insulin synthesis and secretion in pancreatic beta-cells is still unclear. Cellular zinc homeostasis is largely maintained by zinc transporters and intracellular zinc binding proteins. In this study, we demonstrated that zinc transporter 7 (ZnT7, Slc30a7) was co-expressed with insulin in the islet of Langerhans in the mouse pancreas. In RIN5mF cells (rat insulinoma cells), ZnT7 was found mainly residing in the perinuclear region of the cell, which is consistent with its Golgi apparatus localization. Over-expression of ZnT7 in RIN5mF cells increased the total cellular insulin content leading to a high basal insulin secretion. Furthermore, glucose-induced insulin secretion was not altered in RIN5mF cells over-expressing ZnT7. Quantitative RT-PCR and (35)S metabolic labeling analysis demonstrated that over-expression of ZnT7 in RIN5mF cells led to an increase of insulin mRNA expression and subsequent insulin protein synthesis in the cell. Metal-responsive elements (MREs) were identified in the promoter regions of the Ins1 and Ins2 genes. Mtf1, a metal-responsive transcription factor, was shown to specifically bind to the MRE in the Ins genes and activated the insulin gene transcription. Together, the data strongly suggest that ZnT7 plays an important role in regulating insulin expression by modulating Mtf1 transcriptional activity. Published by Elsevier Inc.

To meet this objective, conservation planners need tools to accurately predict phosphorus (P) loss from agricultural lands. Existing P export coefficient based tools are easy to use, but do not adequately account for local conditions. Hydrologic and water quality models are more accurate, but are prohibitively complex for conservation planners to use. Pasture Phosphorus Management (PPM) Plus was developed as a user-friendly P and sediment loss prediction tool based on the Soil and Water Assessment Tool (SWAT), a popular comprehensive hydrologic and water quality model. PPM Plus is applicable under a wide variety of management options and conservation practices and simple enough for use by conservation planners. SWAT hydrologic components were calibrated to allow application anywhere in the State of Oklahoma. The SWAT model was modified to include soil P algorithm updates and improved representation of conservation practices. This tool was successfully validated using 286 field years of measured data from the southern United States. PPM Plus allows the development of more effective conservation plans by allowing planners to evaluate pollutant losses resulting from a particular management strategy prior to implementation.

DNA extracted from fermenter samples was analyzed by denaturing gradient gel electrophoresis (DGGE). A significant decrease in diversity was observed, the Shannon-Weaver index dropped from 1.92 to 1.13 after 14 days of fermentation. Likewise, similarity of fermenter communities to those in the fecal inoculum also decreased over time. Both diversity and similarity to the inoculum decreased most rapidly in the first few days of fermentation, reflecting a period of adaptation. Sequencing of DGGE bands indicated that the same species were present in replicate fermenters. Most of these bacteria were placed in theClostridium coccoides/Eubacterium rectale group (likely saccharolytic butyrate producers), a dominant bacterial group in the intestinal tract of pigs. DGGE proved useful to monitor swine fecal communities in vitro and indicated the selection and maintenance of native swine intestinal bacteria during continuous culture.

The objectives of this research were to determine the effects of glyphosate drift from a single aerial application (18.3 m swath, 866 g AE ha-1) on corn injury, chlorophyll content, shikimate level, plant height and shoot dry weight in non-glyphosate-resistant (non-GR) corn. RESULTS: One week after application (WAA), corn was killed at 3 m from the edge of the spray swath, with injury decreasing to 18% at 35.4 m downwind. Chlorophyll content decreased from 78% at 6 m to 22% at 15.8 m, and it was unaffected beyond 25.6 m at 1 WAA. Shikimate accumulation in corn decreased from 349% at 0 m to 93% at 15.8 m, and shikimate levels were unaffected beyond 25.6 m downwind. Plant height and shoot dry weight decreased gradually with increasing distance. At a distance of 35.4 m, corn height was reduced by 14% and shoot dry weight by 10% at 3 WAA. CONCLUSIONS: Corn injury and other biological responses point to the same conclusion, that is, injury from glyphosate aerial drift is highest at the edge of the spray swath and decreases gradually with distance. The LD50 (the lethal distance that drift must travel to cause a 50% reduction in biological response) ranged from 12 to 26 m among the biological parameters when wind speed was 11.2 km h-1 and using a complement of CP-09 spray nozzles on spray aircraft.

Synephrine is structurally similar to the active ingredients of several commercial cold remedies. Some Citrus contain high concentrations of synephrine. An enzyme involved in synephrine biosynthesis, tyrosine decarboxylase (TYDC), is a pyridoxal-5'-phosphate (PLP)-dependent enzyme that decarboxylates tyrosine to yield CO sub(2) and tyramine. We used PCR to screen, clone and sequence this gene from various synephrine producing and nonproducing Citrus species and varieties to determine if DNA sequence of this gene correlated with synephrine presence. Results - PCR amplification and comparison of DNA sequence indicates DNA sequence differences that may cause production of truncated proteins to be produced in some nonsynephrine producing Citrus. Conclusion - Synephrine production may be genetically determined in part by the gene for TYDC.

We assessed the short-term effects of alternative designs of forested buffer treatments along headwater streams on small ground-dwelling mammals in managed forests in western Washington, USA. Over three summers (one pretreatment and two posttreatment), we trapped 19 mammalian species along 23 streams in the northern Coast Range. We compared faunal communities in unlogged controls with riparian treatments: (1) clearcuts (no buffer) to the stream bank, (2) clearcuts with continuous buffer strips from a few to 20m each stream side, and (3) clearcuts with small patch (<0.6ha) buffers left to protect sensitive streamside terrain. We estimated abundance ( N Ee ) of eight common and three less common species with simple models and capture indices, respectively, and analyzed effects of treatments and community measures on relative abundance compared to controls and over time. Habitat and forest stand changes after treatments included reduced live standing trees and canopy, more dead down wood, and increased ground plant species richness, evenness, and diversity, particularly in the patch and no buffers. The forest obligate Peromyscus keeni significantly declined in all treatments. No other species declined in strip buffers. Species with statistically greater N Ee in treatments included the early-seral microtine Microtus oregoni, the semi-arboreal generalist Tamias townsendii and the old forest specialist Myodes gapperi in all treatments; the generalist Peromyscus maniculatus in strip and no buffers; and the early-seral riparian Zapus trinotatus in patch buffers. Postlogging trends in N Ee were negative for two common shrews, Sorex monticolus and Sorex trowbridgii. Moist soil denizen Neurotrichus gibbsii capture rates were significantly lower in clearcut no buffers. Captures were low for two species of semi-aquatic shrews, Sorex bendirii and Sorex palustris, but in general, S. palustris responded poorly to treatments. Windfall was an important proximate influence on buffer function because persistence was low and created structural diversity in dynamic change. The alternative buffers were ineffective in retaining the habitat and relative abundance of individual small mammal species. Species composition similarity also significantly declined in the clearcuts. Change in species richness, evenness, diversity and total mammals captured in treatments however were not different. Control streams maintained faunal biodiversity but abundance of about half of the species changed following treatment. Steep topography, weather events, and small buffer size advanced habitat changes that influenced small mammal response to treatments. Site-specific data are necessary in logging unit planning along headwater streams, if the management goal is the maintenance of communities observed in undisturbed forest.

Recent large-scale, severe wildfires in the western United States have prompted extensive mechanical fuel treatment programs to reduce potential wildfire size and severity. Fuel reduction prescriptions typically target non-merchantable material so approaches to mechanically treat and distribute residue on site are becoming increasingly common. We examined how mulch treatments alter the distribution of woody material by size class by comparing paired mulched and untreated sites in lodgepole pine (Pinus contorta), mixed conifer, ponderosa pine (Pinus ponderosa), and pinyon pine/juniper (Pinus edulis/Juniperus sp.) forests 2-6 years after mechanical treatment. Mulching treatments reduced tree density and canopy bulk density, and increased canopy base height, potentially lowing active crown fire risk. In general, mulching increased total woody surface fuel loadings 2-3-fold, but the magnitude differed among forest types. Average total woody surface fuel loads in the untreated areas ranged between 7 and 12Mghaa1, but increased to 27-63Mghaa1 in treated areas. Large diameter fuels (>7.62cm) represent about 35-69% of the total woody fuel load in the untreated areas, but only about 8-14% of the total fuel load in the treated areas. Woody fuels in treated areas were dominated by material <2.54cm diameter (i.e. 1 and 10h fuels). In general, mulch fuelbed depth was a useful predictor of fuel loading. Mulching created a compact fuelbed (i.e. bulk density 138-150kgma3) that differs from pretreatment needle-dominated fuelbed and will likely change fire behavior and effects.

One of the arguments against using prescribed fire to regenerate oak (Quercus spp.) forests is that the improvement in species composition of the hardwood regeneration pool is temporary and multiple burns are necessary to achieve and maintain oak dominance. To explore this concern, I re-inventoried a prescribed fire study conducted in the mid-1990s to determine the longevity of the effects of a single prescribed fire on hardwood regeneration. The initial study was conducted in three oak shelterwood stands in central Virginia, USA. In 1994, each stand was divided into four treatments (spring, summer, and winter burns and a control) and the hardwood regeneration was inventoried before the fires. During the burns, fire intensity was measured and categorized in each regeneration sampling plot. Second-year postfire data showed marked differences in species mortality rates, depending on season-of-burn and fire intensity: oak and hickory (Carya spp.) regeneration dominated areas burned by medium- to high-intensity fire during the spring and summer while yellow-poplar (Liriodendron tulipifera) and red maple (Acer rubrum) seedlings dominated unburned areas and all areas treated with low-intensity fire regardless of season-of-burn. The treatments were re-inventoried in 2006 and 2007 to determine whether these fire effects were still present. The new data show that the species distributions by season-of-burn and fire intensity found in 1996 still existed 11 years after the treatments. The fact that fire effects in oak shelterwood stands can last at least a decade has important management implications for resource professionals interested in sustaining oak forests in the eastern United States.

The fisher is warranted for protection under the Endangered Species Act in the western United States and, as such, it is especially important that conservation and management actions are based on sound scientific information. We developed a landscape-scale suitability model for interior northern California to predict the probability of detecting fishers and to identify areas of important fisher habitat. Previous models have been extrapolated to this region, but our model was developed from the results of strategically planned detection surveys within the study area. We used generalized additive modeling to create a model that best distinguished detection (n =55) from non-detection (n =90) locations on the basis of environmental covariates. Four models were averaged to create a final model including the following variables: Amount of Dense Forest, Percent Hardwood, Medium & Large Trees, Structurally Complex Forest, Adjusted Elevation, Insolation Index and Predicted Abundance of Mammalian Prey. This model was well calibrated and correctly classified fisher detections 83.6% of the time and absences (non-detections) 70.0%. Independent test data were classified less well; 76.2% and 53.0%, respectively, perhaps a result of differences in the spatial and temporal characteristics of the data used to build versus test the model. The model is the first comprehensive portrayal of the distribution and configuration of habitat suitability in this region and provides managers a tool to monitor habitat change over time and to plan vegetation treatments. It also represents an example for the development of similar models for dispersal-limited mammals with large area needs, as well as other species associated with late-successional forests in northern California.

ACoAAT, also known as thiolase (EC 2.3.1.9), is encoded by the thl gene and catalyzes ligation of two acetyl-CoA into acetoacetyl-CoA. Bioinformatics analyses suggest there are no thl in the genomes of lactic acid bacteria (LAB), in this study we aimed to introduce the thl gene into selected LAB strains and analyze the fermentation products. The thl gene from Clostridium beijerinckii P260 was amplified by genomic PCR using gene-specific primers designed from the published genome sequences of C. beijerinckii NCIMB 8025. The 1.2 kb thl gene was cloned into the pETBlue vector and overexpressed in Escherichia coli Tuner (DE3) pLacI cells. Functional enzyme activity was detected spectrophotometrically by measuring the decrease in absorbance at 303 nm, which reflects the change in acetoacetyl-CoA concentrations. The thl gene was subsequently introduced into Lactococcus lactis and Lactobacillus buchneri strains, and GC analysis indicated about 28 mg/L and 66 mg/L of butanol was produced in the recombinant strains, respectively. This study reports the first step toward developing a butanolgenic LAB through the introduction of the butanol pathway into butanol-tolerant strains of LAB.

In this project, we evaluated two methods of mapping burn severity in the context of rapid post-fire assessment for four wildfires in western Montana using 64 plots as field reference: (1) an image-based burn severity mapping approach using the Differenced Normalised Burn Ratio, and (2) a fire effects simulation approach using the FIREHARM model. The image-based approach was moderately correlated with percentage tree mortality but had no relationship with percentage fuel consumption, whereas the simulation approach was moderately correlated with percentage fuel consumption and weakly correlated with percentage tree mortality. Burn severity maps produced by the two approaches had mixed results among the four sampled wildfires. Both approaches had the same overall map agreement when compared with a sampled composite burn index but the approaches generated different severity maps. Though there are limitations to both approaches and more research is needed to refine methodologies, these techniques have the potential to be used synergistically to improve burn severity mapping capabilities of land managers, enabling them to quickly and effectively meet rehabilitation objectives.

This single-issue focus recalls a management planning process practiced frequently in recent decades - a least-harm approach where the primary objective is first addressed and then plans are modified to mitigate adverse effects to other resources. In contrast, we propose a multiple-criteria process for planning fuel-treatment projects in the context of ecosystem management. This approach is consistent with policies that require land management activities be designed to meet multiple-use and environmental objectives, while addressing administrative and budget constraints, and reconciling performance measures from multiple policy directives. We present the process borrowing from the Trapper Bunkhouse Land Stewardship Project example to show the logic for conducting an integrated assessment of ecological and natural resource issues related to multiple management scenarios. The effects and trade-offs of the no-action scenario and proposed action alternatives are evaluated relative to silviculture, disturbance processes (including fire behaviour), wildlife habitat, noxious weeds, water quality, recreation and aesthetics, and economic contributions. Advantages and challenges of this project planning approach are also discussed.

Little, however, is known about the effects of biochar applications on temperate region soils. Our objective was to quantify the impact of biochar on leaching of plant nutrients following application of swine manure to a typical Midwestern agricultural soil. Repacked soil columns containing 0, 5, 10, and 20 g-biochar kg super(- 1)-soil, with and without 5 g kg super(- 1) of dried swine manure were leached weekly for 45 weeks. Measurements showed a significant decrease in the total amount of N, P, Mg, and Si that leached from the manure-amended columns as biochar rates increased, even though the biochar itself added substantial amounts of these nutrients to the columns. Among columns receiving manure, the 20 g kg super(- 1) biochar treatments reduced total N and total dissolved P leaching by 11% and 69%, respectively. By-pass flow, indicated by spikes in nutrient leaching, occurred during the first leaching event after manure application for 3 of 6 columns receiving manure with no biochar, but was not observed for any of the biochar amended columns. These laboratory results indicate that addition of biochar to a typical Midwestern agricultural soil substantially reduced nutrient leaching, and suggest that soil-biochar additions could be an effective management option for reducing nutrient leaching in production agriculture.

We investigated the impact of biochar amendments (0, 5, 10, and 20 g-biochar kg super(- 1) soil) on the quality of a Clarion soil (Mesic Typic Hapludolls), collected (0-15 cm) in Boone County, Iowa. Repacked soil columns were incubated for 500 days at 25 C and 80% relative humidity. On week 12, 5 g of dried and ground swine manure was incorporated into the upper 3 cm of soil for half of the columns. Once each week, all columns were leached with 200 mL of 0.001 M CaCl sub(2). Soil bulk density increased with time for all columns and was significantly lower for biochar amended soils relative to the un-amended soils. The biochar amended soils retained more water at gravity drained equilibrium (up to 15%), had greater water retention at - 1 and -5 bars soil water matric potential, (13 and 10% greater, respectively), larger specific surface areas (up to 18%), higher cation exchange capacities (up to 20%), and pH values (up to 1 pH unit) relative to the un-amended controls. No effect of biochar on saturated hydraulic conductivity was detected. The biochar amendments significantly increased total N (up to 7%), organic C (up to 69%), and Mehlich III extractable P, K, Mg and Ca but had no effect on Mehlich III extractable S, Cu, and Zn. The results indicate that biochar amendments have the potential to substantially improve the quality and fertility status of Midwestern agricultural soils.

In contrast to other picornaviruses that encode a single copy of 3B, foot-and-mouth disease virus (FMDV) encodes three copies of 3B. Viruses containing disrupted native sequence or deletion of one of their three 3B proteins were derived from a FMDV A24 Cruzeiro full-length cDNA infectious clone. Mutant viruses had growth characteristics similar to the parental virus in cells. RNA synthesis and protein cleavage processes were not significantly affected in these mutant viruses. Cattle infected by aerosol exposure with mutant viruses developed clinical disease similar to that caused by the parental A24 Cruzeiro. Therefore, severe domain disruption or deletion of individual 3B proteins in FMDV do not affect the virus' ability to replicate in vitro and cause clinical disease in cattle.

Tall fescue can harbor the obligate endophyte, Neotyphodium coenophialum that is asexually propagated and transmitted via host seeds. Total RNA was isolated from pseudostems of known endophyte-infected (E+) and endophyte-free (E-) plants and tested in triplicate on the Affymetrix Wheat Genome Array GeneChip and Barley1 Genome Array GeneChip. Overall 14-15% and 17-18% of the probe sets were called present on the wheat and barley chips, respectively. In order to identify genes that were specifically differentially expressed between the E+ and E- tall fescue, a combination of both barley and wheat target sequences that were differentially expressed (greater than twofold) that were similar on both chips on both barley and wheat arrays yielded 32 probe set (genes) that were differentially expressed. Tall fescue ESTs were identified for a number of the probe sets that were differentially expressed on the barley and wheat arrays. PCR primers were designed to fescue ESTs and tested to verify the expression profile observed in the microarray experiments. Some primers confirmed the expected results, although in other cases no differences were observed between the E+ and E- plants, or the results were contrary to what was expected. Our results suggest that while some differentially expressed genes were identified by this method, the cross-species hybridization appears to have significant limitations for the transcriptome analysis of tall fescue.

However, the presence of antibiotic resistant bacteria in biological aerosols and litter is largely not understood. The purpose of this study was to determine the amount of aerosolized bacteria and endotoxin, particularly fecal indicators, staphylococci, and enterococci, associated with poultry house and outdoor air. Aerosol samples were collected at multiple locations on the farm and in the house. Antibiotic resistance was investigated using the Kirby Bauer method on selected isolates using twelve different antibiotics spanning both narrow to broad spectrums of effectiveness. Overall there was a cyclical increase in bacterial concentrations as flocks progressed from pre-flock to late-flock, with >2 orders magnitude lower concentration during pre-flock periods (no chickens), in both the litter and aerosol samples. The house environment provided for significantly concentrated bacterial and endotoxin levels. It was estimated that Staphylococcus bacteria accounted for at least 90% of cultured aerobic bacteria and culture-independent 16S rRNA analyses demonstrated that significant population changes occurred from pre- to late-flock. Rarely was an isolate resistant to more than 4 antibiotic classes; however there was a trend upwards in overall resistance of enterococci as the flock cycle progressed. It appears that although levels of antibiotic resistant bacteria were highly concentrated within the house, levels were much lower outside of the house, and very little house escape occurred.

Because of the high input costs for maize production, farmers need to have a tool that will help them assess the risk associated with dryland maize production. The objectives of this work were to determine the critical period for precipitation during the maize growing season and to develop a relationship between critical period precipitation and maize yield to use as a tool to quantify expected yield variability associated with dryland maize production in this region. Maize yield data were collected at Akron, CO from two dryland cropping systems experiments (1984-2009) in which maize was grown in a 3-year winter wheat (Triticum aestivum L.)-maize-fallow rotation. Yields were correlated with weekly precipitation amounts from planting to harvest in search of the period of time in which yield was most influenced by precipitation. Soil water contents at planting were measured either by gravimetric sampling or by neutron attenuation. Yields were found to be most closely correlated with precipitation occurring during the 6-week period between 16 July and 26 August. The data separated into two linear relationships defined by whether the sum of available soil water at planting and May precipitation was less than or greater than 250 mm. These two linear relationships between precipitation during this critical period and yield were used with long-term precipitation records to determine the probability of obtaining a maize yield of at least 2500 kg ha super(-1) (generally considered to be a break-even yield) at three locations across the central Great Plains precipitation gradient. This analysis quantified the production risk associated with the highly variable corn yields that result from erratic summer precipitation in this region.

Geographic data layers were acquired for Crook County, Wyoming, and the potential distribution of leafy spurge presence or absence were predicted with the use of the Weed Invasion Susceptibility Prediction (WISP) model. Hyperspectral imagery and field data were acquired in 1999 over parts of the study area. Leafy spurge presence or absence was classified with the use of the Spectral Angle Mapper with a 74% overall accuracy. However, the user accuracy was 93%, showing that where leafy spurge was indicated in the image, leafy spurge was usually found at that location. With the use of Kappa analysis, there was no agreement between WISP model predictions and either the field data or the classified hyperspectral image. Kappa analysis was then used to compare predictions based on single geographic data layers, to increase the power to detect subtle relationships between independent variables and leafy spurge distribution. The WISP model was revised for leafy spurge based on the remote-sensing analyses, and only a few variables contributed to predictions of leafy spurge distribution. The revised model had significantly increased accuracy, from 52.8% to 61.3% for the field data and from 30.4% to 80.3% for the hyperspectral image classification, primarily by reducing the areas predicted to have potential for invasion. It is generally more cost effective to deal with the initial stages of invasion by only a few plants, compared to an invasion that is large enough to be detected by remote sensing. By reducing the potential area for monitoring, management of invasive plants could be performed more efficiently by field crews.

Still, even with its use, live Mycoplasma gallisepticum (MG) vaccinations have been questionable in terms of seroconversion. Using the vaccinator as a research tool over the past 5yr, factors have been elucidated which impact seroconversion to one live MG vaccine in particular, the F strain of MG (FMG). These factors include the type of nozzle used to spray the vaccine, the temperature of the water used to rehydrate and administer the vaccine, and the pH and osmolarity of the fluid used to apply the vaccine. In the present study, one farm was monitored for its seroconversion rates over 4[frac12] yr, during which time the FMG vaccination protocol was amended as factors were identified that enhanced seroconversion rates. The results of this study showed that implementation and inclusion of the optimized factors into the vaccination protocol for FMG enhanced seroconversion rates because they went from an initial 50%-55% positive seroconversion rate to a consistent 100% positive seroconversion rate over the 56-mo study period.

Although the organism was originally classified as non-beta-hemolytic, recent North American field isolates of O. rhinotracheale obtained from pneumonic lungs and air sacs indicated hemolytic activity on blood agar plates upon extended incubation for 48 hr at room temperature in air after initial incubation at 37 C for 48 hr under 7.5% CO2. This report characterizes the beta-hemolytic activity of O. rhinotracheale isolates by using in vitro kinetic hemolysis assays with sheep red blood cells, western blotting with leukotoxin-specific monoclonal antibodies, and isobaric tagging and relative and absolute quantitative (iTRAQ) analysis of O. rhinotracheale outer membrane protein digest preparations. The kinetic analyses of the hemolytic activity with red blood cells indicated that the protein is a pore former. iTRAQ analysis with membrane preparations revealed four peptides with homology to Mannheimia haemolytica leukotoxin and two peptides with homology to Actinobacillus actinoacetemcomitans leukotoxin. This is the first report that North American field isolates of O. rhinotracheale may express a hemolysin-like activity.

The resulting polymers had molecular weight ranging from 21,842 to 118,300g/mol. Nuclear magnetic resonance spectroscopy and gel permeation chromatography analysis confirmed the polymerization had occurred. Parameters affecting the polymerization were studied, which included initiator amount and reaction time. Results show that the longer reaction time, up to 3h, favored the higher molecular weight of polymers at conditions of 140 degree C and initiator BF sub(3).OEt sub(2) (2.5g, 0.018mol). When reaction time was increased further, the molecular weight of polymers stayed the same or slightly decreased. Increased concentration of initiator gave the higher molecular weight of polymers. The high molecular weight polymers were possibly formed through two path ways: polymerization and intermolecular Diels-Alder reaction.

Pesticide resistance has become a substantial problem for cattle producers, and although several mechanisms of resistance are possible, target site resistance is the most important mechanism preventing control of this fly in the United States and possibly other countries. We developed a multiplex polymerase chain reaction assay to detect the known target site, pyrethroid resistance-associated mutation in the horn fly and a recently reported G262A mutation in the horn fly acetylcholinesterase, the target site for organophosphates. As expected, the pyrethroid resistance target site mutation was found in fly populations from Texas, Louisiana, Washington, Georgia, Mexico, and Brazil. This mutation was found to have a gender bias as it was more prevalent in females than males. The G262A acetylcholinesterase mutation was found in Texas, Louisiana, Washington, Georgia, and Mexico, but not Brazil. There was no gender bias in the occurrence of this mutation, and there was no correlation between the occurrence of the kdr and the G262A mutations. Unlike the case with the pyrethroid target site mutation, the presence of G262A did not appear to exclusively provide the level of resistance required to account for bioassay results. It is likely an additional mutation (s) occurs in the target site and/ or a metabolic resistance mechanism exists in organophosphate-resistant horn fly populations.

This article presents three case studies on the use of hyperspectral remote sensing for mapping invasive plant species in both terrestrial and aquatic environments. Methods and procedures for acquisition, processing and classification of airborne hyperspectral imagery as well as accuracy assessment are presented. Examples are excerpted and adapted from published work to illustrate how airborne hyperspectral imagery has been used to map two terrestrial weeds, Ashe juniper (Juniperus ashei Buchholz) and Broom snakeweed [Gutierrezia sarothrae (Pursh.) Britt. and Rusby], and one aquatic weed, waterhyacinth [Eichhornia crassipes (Mart.) Solms], in Texas. In addition to the standard classification methods used in the previous studies, a spectral unmixing technique, mixture tuned matched filtering (MTMF), was applied to the three study cases and the classification results are reported in this paper. A brief discussion is provided on the considerations of different types of remote sensing imagery for mapping invasive weeds.

It can be used to evaluate wildfire potential by either providing meteorological conditions for computation of fire indices or predicting soil moisture as a direct measure of fire potential. This study examines these roles using a regional climate model (RCM) for the drought and wildfire events in 1988 in the northern United States. The National Center for Atmospheric Research regional climate model (RegCM) was used to conduct simulations of a summer month in each year from 1988 to 1995. The simulated precipitation and maximum surface air temperature were used to calculate the Keetch-Byram Drought Index (KBDI), which is a popular fire potential index. We found that the KBDI increased significantly under the simulated drought condition. The corresponding fire potential was upgraded from moderate for a normal year to high level for the drought year. High fire potential is often an indicator for occurrence of intense and extensive wildfires. Fire potential changed in the opposite direction for the 1993 flood event, indicating little possibility of severe wildfires. The soil moisture and KBDI evaluations under the drought and flood conditions are in agreement with satellite remotely sensed vegetation conditions and the actual wildfire activity. The precipitation anomaly was a more important contributor to the KBDI changes than temperature anomaly. The small magnitude of the simulated soil moisture anomalies during the drought event did not provide sufficient evidence for the role of simulated soil moisture as a direct measure of wildfire potential.

Under optimal conditions, overwintering propagules germinate and produce conidia that are dispersed as primary inoculum to initiate infection in sugar beet. We developed a polymerase chain reaction (PCR) technique for rapid detection of C. beticola in field soils. Total DNA was first isolated from soil amended with C. beticola culture using the PowerSoil DNA Kit. The purified DNA was subjected to PCR in Extract-N-Amp PCR mix with CBACTIN primers over 35 cycles. The amplified products were resolved and compared by electrophoresis in 1% agarose gels. The PCR fragment size of C. beticola from the amended field soil correlated in size with the amplicon from control C. beticola culture DNA extract. Additionally, sample soils were collected from sugar beet fields near Sidney, MT and Foxholm, ND. Total DNA was extracted from the samples and subjected to PCR and resolved as previously described. The amplicons were purified from the gels and subjected to BigDye Terminator Cycle sequencing. All sequences from field soils samples, C. beticola-amended field soil, and pure culture were compared by alignment with a C. beticola actin gene sequence from GenBank. The result of the alignment confirmed the amplicons as products from C. beticola. Rapid screening for the presence of C. beticola in the soil by PCR will improve research capabilities in biological control, disease forecasting, and management of this very important sugar beet pathogen.

To facilitate MF, LEW was wedge screened, homogenized and then diluted (1:2 w/w) with distilled water containing 0.5% sodium chloride. Diluted unpasteurized LEW was inoculated with five strains of S. Enteritidis (ATCC 4931, ATCC BAA-708, ATCC 49215, ATCC 49218, and ATCC BAA-1045) to a level of approximately 10 super(7) CFU/mL of LEW and microfiltered using a ceramic membrane. Process parameters influencing egg white functional properties and pathogen removal efficiency were evaluated. Average permeates flux increased by almost 126% when pH of LEW was adjusted from pH 8 to pH 7 at 25 degree C. Microbial removal efficiency was at least, on average, 6.8 Log sub(10) CFU/mL (limit of detection <= 0.5 Log sub(10) CFU/mL). Functional property analysis indicated that the MF process did not alter the foaming power of LEW.

However, obtaining samples (e.g., bone or teeth) to assess tetracycline uptake is highly invasive, and sample preparation can be expensive. By contrast, rhodamine B, a commercially available dye, is absorbed systemically in growing tissues, including hair and whiskers, and can be observed under ultraviolet (UV) light as fluorescent orange bands. Our goal was to evaluate whether rhodamine B can be used as a biomarker to monitor bait uptake by raccoons. We began by orally administering a solution containing 100 mg, 150 mg, or 200 mg of rhodamine B to captive raccoons. We monitored whisker and hair samples for fluorescence using a hand-held UV lamp and a fluorescent microscope for 13-weeks post-treatment. All raccoons that were administered rhodamine B exhibited fluorescence in their whisker and hair samples during the course of the study. Our ability to detect fluorescing whiskers varied based on the method of detection and time interval, but not with rhodamine B dosage level. We detected rhodamine B in 81% of marked individuals using the fluorescent microscope and 58% of marked subjects using the UV lamp. We were able to detect rhodamine B when doses as low as 1 mg/kg were given. Raccoons did not exhibit a taste aversion to baits containing less than or equal to 3% rhodamine B. We believe that rhodamine B can be a useful biomarker for raccoons and has potential as an application to monitor the uptake of oral rabies vaccine.

Objectives here were to determine yeast extract:sucrose ratios that maximize egg loads without compromising survival in western cherry fruit fly, Rhagoletis indifferens Curran, and their effects on mortality caused by spinosad bait (GF-120). Yeast extract:sucrose ratios of 20:80 and 30:70 maximized egg loads without reducing survival in most cases. In 1 experiment, mortality of flies with low to high egg loads exposed to fresh GF-120 for 1 or 2 h in the absence of food did not differ. In a separate experiment, egg loads were lowest in flies fed 0:100 and 1:99 diets and highest in flies fed 20:80, 30:70, and 50:50 diets. When these flies were exposed to dried GF-120 for 6 h in presence of yeast extract and sucrose, percent mortality was lower in flies fed 20:80 and 30:70 (40%) than 0:100 (69%) and 1:99 (63%) diets. In another experiment, egg loads were lowest in flies fed 0:100 and 1:99 diet and highest in flies fed 20:80 diet. When these flies were exposed to dried GF-120 for 6 h in the presence of sucrose only, percent mortality was lower in flies fed 20:80 (39%) than 0:100 (72%) and 1:99 (62%) diets. High yeast extract:sucrose ratios result in high egg loads in R. indifferens and may reduce the fly's feeding responses to GF-120, although not to the extent that the bait is rendered completely ineffective.

It is of potential use in biological control as a complement to parasitoids that attack larvae infesting fruit still on the tree and to parasitoids that can only oviposit into larvae near the surface of the fruit, because Odontosema pursues larvae deep within the pulp. A newly discovered Mexican all-female (presumably thelytokous) population, provisionally referred to here as O. near anastrephae, appears to be morphologically indistinguishable from arrhenotokous individuals. Thelytokous reproduction can potentially lower costs in mass rearing facilities and increase parasitoid efficacy in the field. PCR amplification and sequencing of mitochondrial (COI) and nuclear (ITS2) genetic sequences suggested that these populations are genetically distinct, but no more so than often occurs among distinct populations within recognized species. In addition to the description of an all-female population of Odontosema, this study presents the first genetic sequence data for members of the genus Odontosema, enabling phylogenetic comparison between Odontosema and other figitid genera and the development of methods for the identification of Odontosema species by PCR. The implications of thelytoky for a cladistic definition of speciation, especially for newly diverging populations such as these, as well as the potential practical implications of our findings for fruit fly biological control, are discussed.

If the purpose of the research is to assess the genetic variance present for an insect trait, e.g., insecticide-resistance monitoring, it is imperative to understand the potential mating dynamics and genetic contributions of adults to the larvae evaluated in bioassays. We report the results of a study utilizing a laboratory-reared colony of Ostrinia nubilalis (Huebner). The changes in the population dynamics (e.g., numbers of males, females, fertile egg masses, mated females) were evaluated. Although the numbers of emerging females, living females, mated females and fertile egg masses changed during the experiment, the percentage of total females that were mated did not change ( similar to 54%). The first of the females to emerge were beginning to die as later-emerging females were mating. Results suggest that experimental designs that rely on laboratory-reared O. nubilalis will need to test larvae from several nights of oviposition to better ensure that the total genetic composition of the population is sampled.

Female mosquitoes were allowed to feed on adult hamsters inoculated with RVFV, after which engorged mosquitoes were incubated for 7-21 d at 26 degree C, then allowed to refeed on susceptible hamsters, and tested to determine infection, dissemination, and transmission rates. Other specimens were inoculated intrathoracically, held for 7 d, and then allowed to feed on a susceptible hamster to check for a salivary gland barrier. When exposed to hamsters with viremias greater than or equal to 108.8 plaque-forming units/ml blood, Cx. tarsalis transmitted RVFV efficiently (infection rate = 93%, dissemination rate = 56%, and estimated transmission rate = 52%). In contrast, when exposed to the same virus dose, none of the other species tested transmitted RVFV efficiently. Estimated transmission rates for Cx. erythrothorax, Cx. pipiens, Cx. erraticus, and Ae. dorsalis were 10, 8, 4, and 2%, respectively, and for the remaining species were less than or equal to 1%. With the exception of Cx. tarsalis and Cx. pipiens, all species tested had moderate to major salivary gland barriers. None of the C. sonorensis became infected and none of the An. quadrimaculatus tested transmitted RVFV by bite, even after intrathoracic inoculation, indicating that these species would not be competent vectors of RVFV. Although Ae. vexans from Florida and Louisiana were relatively efficient vectors of RVFV, specimens of this species captured in Colorado or California were virtually incompetent, illustrating the need to evaluate local population for their ability to transmit a pathogen. In addition to laboratory vector competence, factors such as seasonal density, host feeding preference, longevity, and foraging behavior should be considered when determining the potential role that these species could play in RVFV transmission.

We evaluated efficacy of a 2.1-m-tall polypropylene mesh (poly-mesh) fence for containing greater than or equal to 15 free-ranging white-tailed deer (O. virginianus) within a 42-ha area in eastern Nebraska, USA. We observed a 99% decrease in deer leaving the enclosure area after we installed fencing (1 deer jumped; 0.02 deer/hr) compared with prefence rates (5.26 deer/hr). However, 8 deer (53% of censused population) escaped the enclosure during a census drive after our study. Poly-mesh fencing may be effective in temporarily containing free-ranging deer during minimally disruptive deer removal actions such as trapping or sharpshooting.

We provide a synthesis of climate change effects on native bark beetles, important mortality agents of conifers in western North America. Because of differences in temperature-dependent life-history strategies, including cold-induced mortality and developmental timing, responses to warming will differ among and within bark beetle species. The success of bark beetle populations will also be influenced indirectly by the effects of climate on community associates and host-tree vigor, although little information is available to quantify these relationships. We used available population models and climate forecasts to explore the responses of two eruptive bark beetle species. Based on projected warming, increases in thermal regimes conducive to population success are predicted for Dendroctonus rufipennis (Kirby) and Dendroctonus ponderosae Hopkins, although there is considerable spatial and temporal variability. These predictions from population models suggest a movement of temperature suitability to higher latitudes and elevations and identify regions with a high potential for bark beetle outbreaks and associated tree mortality in the coming century.

The estimated LT50 and the LT90 for large/small females were significantly shorter for test populations receiving water (5.1/3.8 d) or water + blood (6.7/5.0 d) than for those receiving sucrose (44.4/31.7 d) or sucrose + blood (41.4/29.2 d). The estimated LT50 and LT90 for large/small males receiving water (respectively: 3.2/2.5 d and 4.8/3.8 d) were significantly shorter than for those receiving sucrose (respectively: 18.8/15.9 d and 34.9/32.6 d). The availability of sucrose to adult mosquitoes extended the maximum life span of large and small male and female Ae. albopictus by 6-8 when compared with the availability of water or water + blood. Results indicate that sugar availability is more important than blood as a nutritional parameter for survival and longevity of Ae. albopictus in the laboratory.

Amphibians that evolved in fishless habitats often lack the necessary chemical defenses and behavioral responses to avoid predation. True Toads (family Bufonidae), however, possess noxious chemicals that often deter predators. Our goal was to test whether eggs, tadpoles, and postmetamorphic toads of A. canorus are a palatable food source for S. fontinalis, assess the antipredator behavior of tadpoles of A. canorus by exposing them to various predator chemical cues, and determine sublethal effects on three lifestages of A. canorus from sampling by S. fontinalis. We found that eggs, tadpoles, and postmetamorphic toads of A. canorus exhibit absolute unpalatability to S. fontinalis. In addition, tadpoles of A. canorus did not exhibit a significant difference in behavior when exposed to chemical stimuli. Moreover, observational experiments revealed that trout would sample, then reject lifestages of A. canorus unharmed, while trout readily consumed tadpoles of Pacific Chorus Frog (Pseudacris regilla). We therefore infer that early lifestages of A. canorus likely possess existing chemical defenses as a result of interactions with native predators that adequately protect them from nonnative trout predation. Although trout removal often leads to the recovery of other Sierra Nevada amphibian populations, trout removal would likely have no effect on populations of A. canorus given our results. Therefore, we suggest that other factors thought to be contributing toward A. canorus decline should be investigated before efforts are concentrated on removing trout from toad habitats.

Bluetongue disease is one of the most economically important arthropod-borne diseases of sheep in North America, because it causes significant morbidity and mortality and can lead to local quarantines and international trade restrictions. Long-lasting repellent pesticides could be applied to sheep as they are moved down from mountain pastures to protect them from biting midges until the 1st frost. We tested long-lasting pesticides on sheep as repellents against C. sonorensis. Both PYthon ear tags with 10% zeta-cypermethrin (9.8g/tag) synergized with 20% piperonyl butoxide (PBO) and a 12-ml low-volume spray application of ready-to-use sheep insecticide (Y-TEX) with 2.5% permethrin and 2.5% PBO in an oil-based formulation were repellent to C. sonorensis for at least 3-5wk after a single application.

An artificial neural network employing CODESSA PRO descriptors was used to construct a quantitative structure-activity relationship model for prediction of novel mosquito repellents. By correlating the structure of these carboxamides with complete protection time, a measure of repellency based on duration, 34 carboxamides were predicted as candidate mosquito repellents. There were four additional compounds selected on the basis of their structural similarity to those predicted. The compounds were synthesized either by reaction of 1-acylbenzotriazoles with secondary amines or by reaction of acid chlorides with secondary amines in the presence of sodium hydride. The biological efficacy was assessed by duration of repellency on cloth at two dosages (25 and 2.5 mu mol/cm2) and by the minimum effective dosage to prevent Aedes aegypti (L.) (Diptera: Culicidae) bites. One compound, (E)-N-cyclohexyl-N-ethyl-2-hexenamide, was superior to N,N-diethyl-3-methylbenzamide (deet) at both the high dosage (22 d versus 7 d for deet) and low dosage (5 d versus 2.5 d for deet). Only one of the carboxamides, hexahydro-1-(1-oxohexyl)-1H-azepine, had a minimum effective dosage that was equivalent or slightly better than that of deet (0.033 mu mol/cm2 versus 0.047 mu mol/cm2).

Producers may be able to reduce inputs for weed management by designing rotations to disrupt population dynamics of weeds. Population-based management in conventional farming has reduced herbicide use by 50% because weed density declines in cropland across time. In this paper, we suggest a 9-year rotation comprised of perennial forages and annual crops that will disrupt weed population growth and reduce weed density in organic systems. Lower weed density will also improve effectiveness of weed control tactics used for an individual crop. The rotation includes 3-year intervals of no-till, which will improve both weed population management and soil health. Even though this rotation has not been field tested, it provides an example of designing rotations to disrupt population dynamics of weeds. Also, producers may gain additional benefits of higher crop yield and increased nitrogen supply with this rotation design.

Resistance to M. phaseolina in commercial soybean cultivars is not common but is needed in locations where the disease is chronic and severe. The objective of this study was to develop a reliable method to produce sufficient M. phaseolina conidia that can be used to inoculate soybean plants in a high-throughput resistance-screening program. Production of pycnidia is not common on most culture media, such as potato dextrose agar, but can be produced on media containing plant parts or oilseed extracts. Seven semi-defined media were tested to induce pycnidia production. Results indicated that the number of pycnidia that were produced by eight M. phaseolina isolates was dependent on induction medium; however, peanut butter extract-saturated filter paper placed over soynut butter extract agar (PESEA) allowed for greater pycnidia and conidia production than the other media tested. Production of pycnidia on PESEA ranged from 269 to 1,082 per plate. There were no differences among isolates in germination of conidia produced on PESEA, which averaged 83 c 2% germination. A conidial suspension from one M. phaseolina isolate produced on PESEA and inoculated onto soybean radicles significantly distinguished (P < 0.01) 'DT97-4290', a soybean genotype with partial resistance to charcoal rot, from a susceptible genotype, 'LS98-0358'. Results of this study indicated that multiple isolates of M. phaseolina from soybean produced sufficient amounts of conidia on PESEA to use as inoculum. This conidia inoculum production method will facilitate soybean charcoal rot resistance screening evaluation with different soybean isolates.

RM cheese, considered the ideal Queso Fresco, contained more moisture than PM cheeses, displayed higher cohesiveness and shear strain and exhibited lower hardness and shear stress. The U.S.-made cheeses were harder and more brittle and crumbly than the Mexican cheeses. The shear stress decreased as fat content increased in all samples, and the shear strain decreased as the pH increased in the Mexican cheeses. An understanding of the differences between the RM and PM versions should allow cheese makers to adjust manufacturing procedures so that PM Queso Fresco cheeses will meet consumer expectations.PRACTICAL APPLICATIONS JF - Journal of Food Quality AU - Tunick, Michael H AU - VAN HEKKEN, DIANE L AD - Dairy Processing and Products Research UnitEastern Regional Research CenterAgricultural Research Service, U.S. Department of Agriculture600 E.

Efficient and accurate methods to estimate switchgrass biomass feedstock supply within a production area will be required by biorefineries. Our main objective was to determine the effectiveness of indirect methods for estimating biomass yields and composition of switchgrass fields. Indirect measurements were conducted in eastern Nebraska from 2003 to 2007 in which switchgrass biomass yields were manipulated using three nitrogen rates (0kg N ha super(-1), 60kg N ha super(-1), and 120kg N ha super(-1)) and two harvest periods (August and post-killing frost). A modified Robel pole was used to determine visual obstruction, elongated leaf height, and canopy height measurements. Prediction models from the study showed that elongated leaf height, visual obstruction, and canopy height measurements accounted for >91%, >90%, and >82% of the variation in switchgrass biomass, respectively. Regression slopes were similar by cultivar ("Cave-in-Rock" and "Trailblazer"), harvest period, and across years indicating that a single model is applicable for determining biomass feedstock supply within a region, assuming similar harvesting methods. Sample numbers required to receive the same level of precision were as follows: elongated leaf height80%) were either uninfected or infected or parasitized with only a single pathogen/parasite while the majority of polygyne colonies (>55%) were infected or parasitized with 2 or more pathogens/parasites simultaneously. Higher pathogen/parasite prevalence among polygyne colonies is attributed to lower genetic relatedness (among nestmates), increased colony longevity, and the proclivity of polygyne colonies to share workers, brood and queens among their interconnected colonies. Evaluation of pairwise co-occurrence data indicated that the pathogens and fly parasites were usually independently distributed among host colonies; however, unknown local factors did cause several significant deviations from expected values.

In comparisons among these four experimental groups, our findings show a significant and correlative up-regulation in the expression of a number of muscle determination and development factors in full-fed (FF) transgenic and domestic coho salmon. Expression of several metabolic genes involved with amino acid turnover and utilization also was correlated between these two faster-growing groups. However, distinct differences between domesticated and FF-transgenic fish were found for some genes involved with muscle cell differentiation, innate immune system, metabolism, and amino acid regulation. Wild-type and ration-restricted growth hormone-transgenic fish correlated very highly in the expression of most genes tested, suggesting that limiting available energy reduces the effects of elevated growth hormone and down-regulates muscle and metabolic regulatory pathways similarly to the reduced potential for growth hormone production seen in wild-type fish.

However, little is known about the speciation and levels of VOCs from poultry production. The objective of this study was the speciation of VOCs from a poultry facility using evacuated canisters and sorbent tubes. Samples were taken during active poultry production cycle and between production cycles. Levels of VOCs were highest in areas with birds and the compounds in those areas had a higher percentage of polar compounds (89%) compared to aliphatic hydrocarbons (2.2%). In areas without birds, levels of VOCs were 1/3 those with birds present and compounds had a higher total percentage of aliphatic hydrocarbons (25%). Of the VOCs quantified in this study, no single sampling method was capable of quantifying more than 55% of compounds and in several sections of the building each sampling method quantified less than 50% of the quantifiable VOCs. Key classes of chemicals quantified using evacuated canisters included both alcohols and ketones, while sorbent tube samples included volatile fatty acids and ketones. The top five compounds made up close to 70% of VOCs and included: 1) acetic acid (830.1I14gma3); 2) 2,3-butanedione (680.6I14gma3); 3) methanol (195.8I14gma3); 4) acetone (104.6I14gma3); and 5) ethanol (101.9I14gma3). Location variations for top five compounds averaged 49.5% in each section of the building and averaged 87% for the entire building.

However, information is lacking quantifying differences in native perennial forb characteristics between mountain big sagebrush [A. tridentata spp. vaseyana (Rydb.) Beetle] and Wyoming big sagebrush [A. tridentata spp. wyomingensis (Beetle & A. Young) S.L. Welsh] plant communities. This information is critical to accurately evaluate the quality of habitat and forage that these communities can produce because many wildlife species consume large quantities of native perennial forbs and depend on them for hiding cover. To compare native perennial forb characteristics on sites dominated by these two subspecies of big sagebrush, we sampled 106 intact big sagebrush plant communities. Mountain big sagebrush plant communities produced almost 4.5-fold more native perennial forb biomass and had greater native perennial forb species richness and diversity compared to Wyoming big sagebrush plant communities (P<0.001). Nonmetric multidimensional scaling (NMS) and the multiple-response permutation procedure (MRPP) demonstrated that native perennial forb composition varied between these plant communities (P<0.001). Native perennial forb composition was more similar within plant communities grouped by big sagebrush subspecies than expected by chance (A=0.112) and composition varied between community groups (P<0.001). Indicator analysis did not identify any perennial forbs that were completely exclusive and faithful, but did identify several perennial forbs that were relatively good indicators of either mountain big sagebrush or Wyoming big sagebrush plant communities. Our results suggest that management plans and habitat guidelines should recognize differences in native perennial forb characteristics between mountain and Wyoming big sagebrush plant communities.

ERS has developed a new index of total factor productivity (TFP) in global agriculture to provide a more comprehensive understanding of longrun sources of agricultural output growth. ERS research shows that the average rate of growth in global agricultural TEF has accelerated in recent decades and accounts for an increasing share of growth in agricultural production. Faster TFP growth has offset declining growth in agricultural land, labor, and other resources, although TFP growth across countries and global regions remains unevenly distributed.

The chemotactic activity of F. columnare was significantly (P<0.05) inhibited when cells were pretreated by sodium metaperiodate, and a major portion of the capsular layer surrounding the cells was removed. Pretreatment of F. columnare with d-mannose, d-glucose and N-acteyl-d-glucosamine significantly (P<0.05) inhibited its chemotaxis activity, whereas pretreatment of cells with d-fructose, l-fucose, d-glucosamine, d-galactosamine, d-sucrose and N-acetyl-d-galactosamine failed to inhibit its chemotactic activity. These results indicate that at least three carbohydrate-binding receptors (d-mannose, d-glucose and N-acteyl-d-glucosamine) associated with the capsule of F. columnare might be involved in the chemotactic responses. The relative transcriptional levels of three gliding motility genes (gldB, gldC, gldH) of F. columnare compared with 16S rRNA gene following the exposure of F. columnare to catfish skin mucus were evaluated by quantitative PCR (qPCR). qPCR results revealed that the transcriptional level of gldH was significantly (P<0.001) upregulated in normal F. columnare at 5 min postexposure to the catfish mucus. However, when F. columnare were pretreated with d-mannose, there was no upregulation of gliding motility genes. Taken together, our results suggest that carbohydrate-binding receptors play important roles in the chemotactic response to catfish mucus.

Cheatgrass exhibits a germination syndrome that is characteristic of facultative winter annuals. Although perennials dominate these communities, native annuals are present at many sites. Germination timing is often an important predictor of competitive interactions, and might determine whether the use of annual species in restoration efforts will be successful. I used a laboratory experiment to determine whether a suite of native annuals exhibit winter or spring annual germination syndromes. Seeds of Amsinckia menziesii var. intermedia, Amsinckia tesselata, Blepharipappus scaber, Descurainia pinnata, Eriastrum sparsiflorum, Lappula occidentalis, Mentzelia veatchiana and Plagiobothrys tenellus were tested for dormancy, and for responsiveness to light, cold stratification and dry after-ripening. Species that would be expected to be most similar to cheatgrass are those that have no requirement for cold stratification and are therefore likely to germinate under autumn or winter conditions. The species that clearly met this criterion in this laboratory study were A. menziesii var. intermedia, A. tesselata, D. pinnata and L. occidentalis. In contrast, B. scaber, E. sparsiflorum, M. veatchiana and P. tenellus had their highest germination after cold stratification and would be expected to be spring germinators. Blepharipappus scaber was not coaxed out of dormancy to a great degree by any of the treatments I applied and may exhibit cue-non-responsive dormancy. Field seed burial experiments, as well as experiments examining the competitive ability of these annuals versus cheatgrass will further inform us about their potential for success in restoration seedings.

Little is known about statistical power and inference in individual-based landscape genetics. Our objective was to evaluate the power of causal-modelling with partial Mantel tests in individual-based landscape genetic analysis. We used a spatially explicit simulation model to generate genetic data across a spatially distributed population as functions of several alternative gene flow processes. This allowed us to stipulate the actual process that is in action, enabling formal evaluation of the strength of spurious correlations with incorrect models. We evaluated the degree to which naive correlational approaches can lead to incorrect attribution of the driver of observed genetic structure. Second, we evaluated the power of causal modelling with partial Mantel tests on resistance gradients to correctly identify the explanatory model and reject incorrect alternative models. Third, we evaluated how rapidly after the landscape genetic process is initiated that we are able to reliably detect the effect of the correct model and reject the incorrect models. Our analyses suggest that simple correlational analyses between genetic data and proposed explanatory models produce strong spurious correlations, which lead to incorrect inferences. We found that causal modelling was extremely effective at rejecting incorrect explanations and correctly identifying the true causal process. We propose a generalized framework for landscape genetics based on analysis of the spatial genetic relationships among individual organisms relative to alternative hypotheses that define functional relationships between landscape features and spatial population processes.

Few studies, however, have reported on oocyst concentrations in swine waste lagoons; none have reported on oocyst viability status, nor has there been a systematic assessment of species/genotype distributions across different types of swine facilities. Ten swine waste lagoons associated with farrowing, nursery, finishing, and gestation operations were each sampled once a month for a year. Oocysts were extracted from triplicate 900-ml effluent samples, enumerated by microscopy, and assessed for viability by dye exclusion/vital stain assay. DNA was extracted from processed samples, and 18S ribosomal DNA (rDNA) genes were amplified by PCR and sequenced for species and genotype identification. Oocysts were observed at each sampling time at each lagoon. Annual mean concentrations of total oocysts and viable oocysts ranged between 24 and 51 and between 0.6 and 12 oocysts ml-1 effluent, respectively. The species and genotype distributions were dominated (95 to 100%) by Cryptosporidium suis and Cryptosporidium pig genotype II, the latter of which was found at eight of the lagoons. The lagoon at the gestation facility was dominated by Cryptosporidium muris (90%), and one farrowing facility showed a mix of pig genotypes, Cryptosporidium muris, and various genotypes of C. parvum. The zoonotic C. parvum bovine genotype was observed five times out of 407 18S rDNA sequences analyzed. Our results indicate that pigs can have mixed Cryptosporidium infections, but infection with C. suis is likely to be dominant.

An increasingly prevalent disease of managed honeybees is caused by the microsporidian Nosema ceranae. Microsporidia are basal fungi and obligate parasites with much-reduced genomic and cellular components. A recent genome-sequencing effort for N. ceranae indicated the presence of machinery for RNA silencing in this species, suggesting that RNA interference (RNAi) might be exploited to regulate Nosema gene expression within bee hosts. Here we used controlled laboratory experiments to show that double-stranded RNA homologous to specific N. ceranae ADP/ATP transporter genes can specifically and differentially silence transcripts encoding these proteins. This inhibition also affects Nosema levels and host physiology. Gene silencing could be mediated solely by Nosema or in concert with known systemic RNAi mechanisms in their bee hosts. These results are novel for the microsporidia and provide a possible avenue for controlling a disease agent implicated in severe honeybee colony losses. Moreover, since microsporidia are pathogenic in several known veterinary and human diseases, this advance may have broader applications in the future for disease control.

In a field study, we evaluated the potential biological control of the caterpillar using eastern tent caterpillar nuclear polyhedrosis virus (ETNPV), a naturally occurring virus that is nearly species-specific. Egg masses were hatched and second instar larvae were fed virus-inoculated foliage to propagate the virus in vivo. Then, a viral pesticide was formulated at concentrations of 104, 106 and 108 polyhedral inclusion bodies per ml. The pesticide was applied to foliage on which second, third and fourth instar caterpillars were feeding. When the majority of surviving larvae reached the sixth instar, colonies were collected and the surviving caterpillars counted. Mean numbers of surviving caterpillars per treatment were compared via 95% bootstrap confidence intervals. The data indicate second instar caterpillars were highly susceptible to the virus, but only at the highest concentration tested. Third instar caterpillars were also somewhat susceptible to high virus concentrations, while fourth instar caterpillars were fairly resistant. Our data provide the strongest evidence to date that ETNPV can be propagated, harvested and refined for formulation as a biological control agent for eastern tent caterpillar. Its use on this insect may be merited in circumstances where landowners and managers need to protect trees and horses.

Some of the difference in performance may be attributed to differences in bulk density between tilled and untilled ground. It is not known if performance rankings of grass cultivars established in clean-tilled ground remain valid in more compacted soil characteristic of no-till seeding. Seedlings of five cultivars of Italian ryegrass (Lolium multiflorum Lam.) [IRG] and five cultivars of tall fescue [Festuca arundinacea Schreb. also known as Lolium arundinaceum Schreb. (Darbysh.)] [TF] were grown in pots of Coyle or Stephenville series soils (sandy loam and loamy sand respectively) packed to 0.75, 0.88 or 1.00 of maximum packing densities, established as 1.47 and 1.68 g cm-3 for Coyle and Stephenville soil respectively. Leaf appearance was measured until seedling harvest at 540 growing degree days after emergence. Increased bulk density decreased leaf appearance rates, reduced final leaf and tiller numbers and aerial and root biomass at harvest in both IRG and TF. Among cultivars within species, there was no difference (P >0.05) in response to measured parameters to change in bulk density. Seedling growth and development of IRG were consistently greater than that of TF but showed greater reduction in response to increased soil bulk density. Soil strength provided a better indicator of likely seedling response to soil compaction than bulk density. The results suggest that cultivar rankings obtained under conventional tillage are likely to be valid with no-till planting.

AN - 748972496; 20730985 AB - Termiticides are applied at concentrations much higher than those used in agricultural settings. The longevity of fipronil has not yet been examined at the rates used for termite control, nor has the compound's movement in the soil been addressed. Fipronil was detected in the eluates of treated soil cones, increasing initially and then decreasing to a steady concentration of about 1 microg mL(-1). In larger PVC pipe plots, fipronil in the top treated soil depth (0-7.5 cm) dissipated more rapidly (half-life of 11-13 months) than in treated soil at the next treated depth (7.5-15 cm; half-life of 20-29 months). The presence of vegetation had no significant effect on the mobility, longevity or movement into untreated depths. Treated soil remained toxic to termites throughout the duration of the study. Fipronil moved into the 15-22.5 cm soil depth in sufficient concentration to cause 100% mortality to eastern subterranean termites in 3 day bioassays. Fipronil remains in treated soil at levels toxic to termites for at least 30 months. Movement of the active ingredient was observed in sufficient amounts to kill termites in non-treated soil directly below the treated soil. Published 2010 by John Wiley & Sons, Ltd.

Experiments were first conducted in homogeneous phases as a function of pH in the presence of ligands that (1) complex iron (e.g., citric acid, oxalic acid), (2) complex and reduce iron (e.g., caffeic acid, ascorbic acid), and (3) humic substances with known carboxyl content and electron transfer capacity. Then, effects of these NOM components on Fe(II) reactivity in heterogeneous media were investigated by introducing goethite. Our results indicate complex catalytic and inhibitory effects of NOM components on the reaction between Fe(II) and 2,4-DNT, depending upon the ability of NOM component to (1) reduce dissolved and particulate Fe(III) (e.g., ascorbic acid), (2) form kinetically labile dissolved Fe(II) reductants (e.g., tiron and caffeic acid), and (3) produce surface-associated Fe(II) species that are accessible to 2,4-DNT.

Weekly air (n = 265) and daily rain samples (n = 494) were collected over 2000 to 2003 from three locations in the Delmarva Peninsula, USA. Pesticides were consistently present in the gas phase with infrequent detection in the particle phase. Hexachlorocyclohexanes (HCHs) and cis- and trans-chlordane were detected most frequently (95-100%), and cis- and trans-nonachlor, oxychlordane, heptachlor, heptachlor epoxide, dieldrin, and 1-chloro-4-[2,2-dichloro-1-(4-chlorophenyl)ethenyl]benzene (4,4'-DDE) were also detected frequently. The highest mean air concentrations were for dieldrin (60-84 pg/m super(3)), -HCH (37-83 pg/m super(3)), and 4,4'-DDE (16-80 pg/m super(3)). Multiple regression analyses of air concentrations with temperature and wind conditions using modified Clausius-Clapeyron equations explained only 30 to 60% of the variability in concentration for most chemicals. Comparison of the air concentrations and enthalpy of air-surface exchange values at the three sites indicate sources of chlordanes and -HCH sources are primarily from long-range transport. However, examination of chlordane isomer ratios indicates some local and regional contributions, and -HCH, 4,4'-DDE, dieldrin, heptachlor, heptachlor epoxide, and oxychlordane also have local or regional sources, possibly from contaminated soils. Median rain sample volumes of 1 to 3 L led to infrequent detections in rain; however, average measured concentrations were 2 to 10 times higher than in the Great Lakes. Dissipation half-lives in air were well below 10 years for all chemicals and below published values for the Great Lakes except dieldrin, which did not decline during the sample period.

Because both rumen digestion and biochemical conversion to ethanol depend upon enzymatic conversion of the cell wall polysaccharides into fermentable sugars, it is probable that grasses bred for increased forage quality would be more amenable for ethanol production. However, it is not known how variation in rumen digestibility and cell wall/fiber components correlates with efficiency of conversion to ethanol via fermentation. The objective of this research was to determine relationships between ethanol production evaluated by simultaneous saccharification and fermentation (SSF), 72-h in vitro ruminal dry matter digestibility (IVDMD), in vitro ruminal gas production after 24 and 96h, and biomass composition for 50 genetically diverse Bermuda grass accessions. The Bermuda grass samples were subjected to standard 72-h IVDMD and forage fiber analyses. Also, in separate labs, gas production was measured in sealed volume-calibrated vials after 24 (NNG24) and 96h (NNG96) of in vitro fermentation by ruminal fluid; ethanol and pentose sugar productions were measured from a bench-top SSF procedure; cell wall constituents were determined by the Uppsala Dietary Fiber Method; and total nitrogen, carbon, and ash concentrations were determined by using the LECO combustion method. Ethanol production was moderately correlated with IVDMD (r=0.55) and NNG96 (r=0.63) but highly correlated with NNG24 (r=0.93). Ethanol was negatively correlated with neutral detergent fiber (NDF; r=-0.53) and pentose sugars (r=-0.60), but not correlated with glucose content. Regression models indicated that NDF and cell wall pentose sugar concentrations had significant negative effects on ethanol production. Variation among entries for IVDMD was affected by variability of NDF, pentose sugar concentrations, and biomass nitrogen content. Variation in Klason lignin content had only minor negative impacts on ethanol production and IVDMD. Biochemical conversion efficiency of Bermuda grass by SSF can be best estimated by NNG24 but not by IVDMD.

In 2007 and 2008, we investigated the effect of irrigation scheduling/control method and amount on cotton (Gossypium hirsutum L.) yield and water use efficiency. Methods were automatic irrigation scheduling and control of a center pivot system, and manually scheduled irrigation to replenish soil-water to field capacity. Cotton was irrigated with LEPA (low energy, precision application) drag socks in furrow dikes; three blocks were irrigated manually and three were irrigated automatically. Six replicates of the manual and automatic irrigation treatments were included in the randomized block design. Manual irrigations were based on the weekly replenishment of soil-water to field capacity in the top 1.5m of the soil profile and included a fully irrigated treatment (I100), and treatments receiving 67% (I67) and 33% (I33) of the I100 amount, plus a non-irrigated treatment (I0). Automatic irrigations were triggered using a time temperature threshold (TTT) algorithm, which was designated as the I100 treatment, and treatments receiving 67%, 33%, and 0% of that amount (I67, I33 and I0, respectively). In 2007, overall mean lint yields (102.3 and 101.6gm super(-2), manual and automatic, respectively) were not significantly different. Similarly, yields were not significantly different across automatic and manual treatments in the same treatment level, with the exception of the I67 treatment where the manual treatment yields were 11% greater. In 2008, the mean yields were 70% less than those in 2007 for both methods of irrigation (30.3 and 30.9gm super(-2), manual and automatic, respectively) due to harsh climatic conditions at emergence and heavy rainfall and cooler temperatures in the month of August. Yields from the automatically irrigated plots in the I100 and I67 treatments, however, were significantly greater than yields from the corresponding manually irrigated plots; though there was no significant difference between yields in the drier treatments (I33 and I0) plots. These results indicate that the TTT algorithm is a promising method for auto-irrigation scheduling of short season cotton in an arid region. However, further studies are essential to demonstrate consistent positive outcomes. JF - Agricultural Water Management AU - O'Shaughnessy, SA AU - Evett AD - USDA-Agricultural Research Service, P.O.

Previous estimates that compared NLCD tree canopy and impervious cover estimates with photo-interpreted cover estimates within selected counties and places revealed that NLCD underestimates tree and impervious cover. Based on these previous results, a wall-to-wall comprehensive national analysis was conducted to determine if and how NLCD derived estimates of tree and impervious cover varies from photo-interpreted values across the conterminous United States. Results of this analysis reveal that NLCD significantly underestimates tree cover in 64 of the 65 zones used to create the NCLD cover maps, with a national average underestimation of 9.7% (standard error (SE)=1.0%) and a maximum underestimation of 28.4% in mapping zone 3. Impervious cover was also underestimated in 44 zones with an average underestimation of 1.4% (SE=0.4%) and a maximum underestimation of 5.7% in mapping zone 56. Understanding the degree of underestimation by mapping zone can lead to better estimates of tree and impervious cover and a better understanding of the potential limitations associated with NLCD cover estimates.

Tree mortality shapes forest development, but rising mortality can represent lost production or an adverse response to changing environmental conditions. Thinning represents a strategy for reducing mortality rates, but different thinning techniques and intensities could have varying impacts depending on how they alter stand structure. We analyzed trends in stand structure, relative density, stand-scale mortality, climate, and correlations between mortality and climate over 46 years of thinning treatments in a red pine forest in Northern Minnesota, USA to examine how thinning techniques that remove trees of different crown classes interact with growing stock manipulation to impact patterns of tree mortality. Relative density in unharvested plots increased during the first 25 years of the study to around 80%, then began to plateau, but was lower (12-62%) in thinned stands. Mortality in unharvested plots claimed 2.5 times more stems yra1 and 8.6 times as large a proportion of annual biomass increment during the last 21 years of the study compared to the first 25 years, but showed few temporal trends in thinned stands. Mortality in thinning treatments was generally lower than in controls, particularly during the last 21 years of the study when mortality averaged about 0.1% of stems yra1 and 4% of biomass increment across thinning treatments, but 0.8% of stems yra1 and 49% of biomass increment in unharvested plots. Treatments that combined thinning from above with low growing stock levels represented an exception, where mortality exceeded biomass production after initial thinning. Mortality averaged less than 0.1% of stems yra1 and less than 1% of annual biomass production in stands thinned from below. These trends suggest thinning from below minimizes mortality across a wide range of growing stock levels while thinning from above to low growing stock levels can result in dramatic short-term increases in mortality. Moderate to high growing stock levels (21-34m2 haa1) may offer greater flexibility for limiting mortality across a range of thinning methods. Mean and maximum annual and growing season temperatures rose by 0.6-1.8AC during the study, and temperature variables were positively correlated with mortality in unharvested plots. Mortality increases in unharvested plots, however, were consistent with self-thinning principles and probably not driven by rising temperatures. These results suggest interactions between thinning method and intensity influence mortality reductions associated with thinning, and demonstrate the need for broader consideration of developmental processes as potential explanations for increased tree mortality rates in recent decades.

The nare and brain of all fish were swabbed and subjected to the STREP B OIA for detection of GBS antigen immediately after swabbing (0 h) or 24, 48 and 72 h post-swabbing and compared to conventional culture on trypticase soy agar with 5% sheep blood. The STREP B OIA method demonstrated a diagnostic sensitivity of 75.0% and a diagnostic specificity of 69.2% compared to direct TSA. The percent agreement between OIA and culture was 100%. GBS antigen could be retrieved by OIA following 72-h storage of swabs. These results demonstrate the utility of the STREP B OIA to identify GBS from culture and directly from swabs of clinically- infected fish.

In this work, a general analytical solution is presented for the linear, one-dimensional advection-dispersion equation with distance-dependent coefficients. An integrating factor is employed to obtain a transport equation that has a self-adjoint differential operator, and a solution is found using the generalized integral transform technique (GITT). It is demonstrated that an analytical expression for the integrating factor exists for several transport equation formulations of practical importance in groundwater transport modeling. Unlike nearly all solutions available in the literature, the current solution is developed for a finite spatial domain. As an illustration, solutions for the particular case of a linearly increasing dispersivity are developed in detail and results are compared with solutions from the literature. Among other applications, the current analytical solution will be particularly useful for testing or benchmarking numerical transport codes because of the incorporation of a finite spatial domain.

The warmer climate has caused significant declines in snow depth, snow water equivalent and snow cover duration. Paradoxically, it has been suggested that warmer air temperatures may result in colder soils and more soil frost, as warming leads to a reduction in snow cover insulating soils during winter. Hubbard Brook has one of the longest records of direct field measurements of soil frost in the United States. Historical records show no long-term trends in maximum annual frost depth, which is possibly confounded by high interannual variability and infrequency of major soil frost events. As a complement to field measurements, soil frost can be modelled reliably using knowledge of the physics of energy and water transfer. We simulated soil freezing and thawing to the year 2100 using a soil energy and water balance model driven by statistically downscaled climate change projections from three atmosphere-ocean general circulation models under two emission scenarios. Results indicated no major changes in maximum annual frost depth and only a slight increase in number of freeze-thaw events. The most important change suggested by the model is a decline in the number of days with soil frost, stemming from a concurrent decline in the number of snow-covered days. This shortening of the frost-covered period has important implications for forest ecosystem processes such as tree phenology and growth, hydrological flowpaths during winter, and biogeochemical processes in soil.

Most fine woody debris (FWD) line-intersect sampling protocols and associated estimators require an approximation of the quadratic mean diameter (QMD) of each individual FWD size class. There is a lack of empirically derived QMDs by FWD size class and species/forest type across the U.S. The objective of this study is to evaluate a technique known as the graphical estimation (GE) method for estimating FWD QMDs across forests of the U.S. Results indicate tremendous inter- and intra-specific variation in small FWD diameters. In addition, GE model fitting results demonstrated a lack of substantial difference in FWD QMDs between common forest types. It is postulated that the mixing, fracturing, and decay of both tree and shrub downed woody debris in diverse forest types across the U.S. can homogenate FWD QMDs at state/national levels. In the absence of site-specific empirical measurement of FWD QMDs, it is suggested that a general national set of FWD QMDs derived from the GE method be adopted for large-scale FWD monitoring efforts.

Phellinus tremulae is an important fungal decay agent common to aspen and a critical component to the cavity-nesting bird complex found in western aspen stands. Little information exists on the conditions that facilitate infection and spread of P. tremulae in aspen forests. I used Forest Inventory and Analysis (FIA) data to explore the relationships of several tree and stand characteristics to the presence and frequency of P. tremulae in aspen measured across several western states of the United States. Results suggest a strong relationship between tree age, tree diameter, and compacted crown ratio with infection frequency in trees while stand purity, canopy cover and stand age had a positive relationship with the occurrence of P. tremulae in forest stands containing aspen. Logistic regression modeling identified stand age as the only variable that increased the odds of predicting infection at the stand-level while all tree-level variables were included in the tree model. Data also show that infection rates in the study area were lower than in other parts of aspen's range, and that average size of infected trees was smaller in the study area than those reported elsewhere. These results have important implications to management of aspen for wildlife, especially for birds that use decayed aspen for nesting.

The continuous agricultural production of tomatoes, green beans, and squash make Miami-Dade County, Florida one of the heaviest users of this pesticide in the country. A field study was initiated at the USDA, Subtropical Horticulture Research Station in Miami, FL to examine the effects of endosulfan on soil respiration. Snap bean (Phaseolus vulgaris) and adjacent bare soil plots were treated either with or without endosulfan. Soil respiration was measured weekly as the difference between CO2 in the ambient air and that generated within a 10-cm diameter, 1178-cm3 chamber secured at the soil surface. Treatments were replicated four times and the study continued over three growing seasons. Respiration from bare soil was similar to that from plots planted with snap bean implying soil microbes were the dominant source of CO2 compared to root respiration. Endosulfan applications resulted in inconsistent increases in soil respiration. Increases were short-lived. By the end of the study more CO2 evolved from endosulfan treated than untreated plots. Soil was kept well irrigated and the percent moisture remained near maximum and varied little, soil moisture was not a controlling factor for soil respiration. Endosulfan had a short-lived inhibitory effect on soil fungi but bacteria increased in number in response to endosulfan application. Individual microbial colonies were not identified and it is possible that one or two bacterial species decomposed the endosulfan and rapidly multiplied causing the increased bacterial colony count. There were no adverse effects of endosulfan found on soil respiration.

The purpose of this study was to quantify CO2 fluxes during the establishment and early production years of a young switchgrass stand in the northeastern USA. Switchgrass was sown in June 2004 and daily CO2 fluxes were measured for four years. Gross primary productivity (GPP) varied little among years, but ecosystem respiration (Re) decreased over time. The switchgrass generally began to take up CO2 in mid-May and continued until early-October, and was a net sink during a 98-day period from late-May through early-September. The rest of the year experienced a net loss of CO2 to the atmosphere. Harvested biomass increased each year and was not related to GPP. The switchgrass field was a net CO2 sink for the first three years, but became a source the final year due to increased removal of C as harvested biomass. This study suggests that in addition to their primary function as a source of renewable energy, switchgrass bioenergy crops in the northeastern USA can sequester CO2 for at least the first few years following establishment.

Seedlings subsequently emerge from the burrows, resulting in an association of the two species (hereafter "LtAt association"). Although populations of these species frequently co-exist in no-till agricultural fields in the eastern U.S. Corn Belt, an association is not always evident. To identify environmental influences on the LtAt association, 30 no-till agricultural fields were surveyed across the eastern U.S. Corn Belt during spring 2007, 2008 and 2009. The LtAt association occurred across states and soil types, but the strength of the association varied with climate differences during the previous September through March. The strongest environmental driver of LtAt association was frequency of "moderate rain day" (MRD; day that received 12.8-25.3mm of precipitation), with a 1-day increase in MRD frequency increasing the odds of LtAt association by a factor of 1.42. Thus, the potential for L. terrestris to cache seeds and facilitate seedling recruitment is increased by precipitation frequency and amount during September through March. These results highlight the importance of climate variation within a region in driving trophic interactions that regulate weed population dynamics.

Their molecular action has only recently been studied, yielding seemingly contradictory theories including odorant-dependent inhibitory and odorant-independent excitatory activities on insect olfactory sensory neurons (OSNs) and odorant receptor proteins (ORs). Here we characterize the action of these repellents on two Aedes aegypti ORs, AaOR2 and AaOR8, individually co-expressed with the common co-receptor AaOR7 in Xenopus oocytes; these ORs are respectively activated by the odors indole (AaOR2) and (R)-(-)-1-octen3-ol (AaOR8), odorants used to locate oviposition sites and host animals. In the absence of odorants, DEET activates AaOR2 but not AaOR8, while 2-U activates AaOR8 but not AaOR2; IR3535 and Picaridin do not activate these ORs. In the presence of odors, DEET strongly inhibits AaOR8 but not AaOR2, while 2-U strongly inhibits AaOR2 but not AaOR8; IR3535 and Picaridin strongly inhibit both ORs. These data demonstrate that repellents can act as olfactory agonists or antagonists, thus modulating OR activity, bringing concordance to conflicting models.

AN - 748939491; 20681643 AB - Ingestion of white snakeroot ( Ageratina altissima ) can cause trembles in livestock and milk sickness in humans. The toxicity has been associated with tremetol, a relatively crude, multicomponent lipophilic extract of the plant. In this study, 11 different compounds were isolated from white snakeroot-derived lipophilic extracts from 18 collections. Six of the isolated compounds have not been previously reported to be found in white snakeroot. High-performance liquid chromatography (HPLC) analysis indicated that there are three different chemotypes of white snakeroot from the plant samples analyzed. Elucidation of these chemotypes may explain the sporadic and unpredictable toxicity of white snakeroot to livestock and humans.

In this study, we use piecewise logistic regression models of crown scorch data from 6633 trees in five wildfires from the Intermountain West to locate a mortality threshold at 88% scorch by volume for trees with no crown consumption. For trees with >40% crown consumption volume, linear regression indicates >85% mortality, but for trees with crown consumption volume 85%), crown consumption volume (>40%), and crown consumption between 5 and 40% combined with crown scorch volume >50% mortality thresholds could be incorporated into post-fire marking guidelines for forest management goals.

Using a recurrent selection strategy, the cultivars with the highest sucrose content are crossed, and a new generation of cultivars is selected from the progeny. This study was designed to determine how selection primarily for sucrose content has modified physiological characters, and impacted sucrose content and yield. Five cultivars were randomly selected from each of seven generations of recurrent selection in Louisiana and planted in two experiments. The plant and first stubble crops were harvested late in the harvest season from each experiment. Cane yield and juice quality were determined. Cultivars from the last three generations were superior to cultivars from the first three generations for Brix % cane, sucrose % cane, purity, theoretically recoverable sugar (TRS), cane yield and sugar yield. Fiber % cane was not different among the generations. Selection primarily for sucrose has increased Brix % cane from 14% to 16%, sucrose % cane from 12% to 14%, purity from 82.5% to 87.3%, and TRS from 98 to 122 kg Mg super(-1). A plateau in juice quality and sucrose yield in the last three generations may indicate that: (1) Louisiana's short growing season may restrict sucrose accumulation; (2) the genetic potential for late season juice quality has been reached with currently available germplasm; or (3) the inclusion of lower juice quality Saccharum spontaneum germplasm into the breeding program in order to increase disease tolerance, cold tolerance, and ratooning ability has diluted the effect of recurrent selection for sucrose.

When plant populations are reduced to 2.0-3.0 plants m super(-2) to conserve soil water for use during grain filling, tillers often form during the vegetative growth and negate the expected economic benefit. We hypothesized that growing maize in clumps spaced 1.0 m apart would reduce tiller formation, increase mutual shading among the plants, and conserve soil water for grain filling that would result in higher grain yield. Studies were conducted during 2006 and 2007 at Bushland, TX. with two planting geometries (clump vs. equidistant), two irrigation methods (low-energy precision applicator, LEPA, and low-elevation spray applicator, LESA) at three irrigation levels (dryland, 75 mm and 125 mm in 2006; and dryland, 50 mm and 100 mm in 2007). For dryland plots in 2007, clump plants had only 0.17 tillers (0.66 tillers m super(-2)) compared with 1.56 tillers per plant (6.08 tillers m super(-2)) for equidistant spacing. Tillers accounted for 10% of the stover for the equidistant plants, but less than 3% of the grain. Clump planting produced significantly greater grain yields (321 g m super(-2) vs. 225 g m super(-2) and 454 g m super(-2) vs. 292 g m super(-2) during 2006 and 2007, respectively) and Harvest Indexes (0.54 vs. 0.49 and 0.52 vs. 0.39 during 2006 and 2007, respectively) compared with equidistant plants in dryland conditions. Water use efficiency (WUE) measurements in 2007 indicated that clumps had a lower evapotranspiration (ET) threshold for initiating grain production, but the production function slopes were 2.5 kg m super(-3) for equidistant treatments compared to 2.0 kg m super(-3) for clump treatments. There was no yield difference for method of irrigation on water use efficiency. Our results suggest that growing maize in clumps compared with equidistant spacing reduced the number of tillers, early vegetative growth, and Leaf Area Index (LAI) so that more soil water was available during the grain filling stage. This may be a useful strategy for growing maize with low plant populations in dryland areas where severe water stress is common.

AN - 748950073; 20526481 AB - Managed turf sites (golf courses) are the most intensively managed landscapes in the urban environment. Yet, long-term watershed scale studies documenting the environmental transport of agrichemicals applied to these systems are rare. The objective of this study was to quantify the surface discharge losses of two commonly applied pesticides (chlorothalonil and 2,4-D) resulting from prevailing practices on a managed golf course. Inflow and outflow discharge waters on a subarea of Northland Country Club located in Duluth, MN were measured for both quantity and quality from April through November from 2003 to 2008. The median chlorothalonil outflow concentration (0.58 microg L(-1)) was significantly greater (p < 0.05) than the inflow concentration, which was below the detection limit (0.07 microg L(-1)). Similarly, the median outflow 2,4-D concentration (0.85 microg L(-1)) was significantly greater (p < 0.05) than the inflow concentration (0.31 microg L(-1)). Chlorothalonil concentrations occasionally exceeded acute toxicity levels (7.6 microg L(-1)) reported for rainbow trout. No 2,4-D concentrations exceeded any human or aquatic species published toxicity level; however, the maximum measured 2,4-D concentration (67.1 microg L(-1)), which rarely occurred, did approach the 70 microg L(-1) maximum contaminant level (MCL) for that compound. Losses of both pesticides were detectable throughout the annual sampling period. Mean annual chlorothalonil loading was 10.5 g ha(-1) or 0.3% of applied, while mean annual 2,4-D loading was 4.9 g ha(-1) or 0.5% of applied. The findings of this study provide quantifiable evidence of agrichemical transport resulting from typical turfgrass management and highlight the need for implementation of best management practices to combat the offsite transport of agrichemicals used in professional turf management.

Below this cell concentration (, 100 -1,000 CFU mL-1 ; , 27-270 CFU well-1) we observed an obvious increase in the t scatter. Working with a food-borne E. coli isolate we found that t values derived from two different microtiter platereader-based techniques (i.e., optical density with growth time {=OD[t]} fit to the sigmoidal Boltzmann equation or time to calculated 1/2-maximal OD {=tm} as a function of initial cell density {=tm[CI]}) were in excellent agreement with the same parameter acquired from total aerobic plate counting. Thus, using either Luria-Bertani (LB) or defined (MM) media at 37C, t ranged between 17-18 (LB) or 51-54 (MM) min. Making use of such OD[t] data we collected many observations of t as a function of manifold initial or starting cell concentrations (CI). We noticed that t appeared to be distributed in two populations (bimodal) at low CI. When CI ,100 CFU mL-1 (stationary phase cells in LB), we found that about 48% of the observed t values were normally distributed around a mean (kt1) of 18 c 0.68 min (c st1) and 52% with kt2 = 20 c 2.5 min (n = 479). However, at higher starting cell densities (CI>100 CFU mL-1), the t values were distributed unimodally (kt = 18 c 0.71 min; n = 174). Inclusion of a small amount of ethyl acetate to the LB caused a collapse of the bimodal to a unimodal form. Comparable bimodal t distribution results were also observed using E. coli cells diluted from mid-log phase cultures. Similar results were also obtained when using either an E. coli O157:H7 or a Citrobacter strain. When sterile-filtered LB supernatants, which formerly contained relatively low concentrations of bacteria(1,000-10,000 CFU mL-1), were employed as a diluent, there was an evident shift of the two populations towards each other but the bimodal effect was still apparent using either stationary or log phase cells. These data argue that there is a dependence of growth rate on starting cell density.

13516104 AB - This review article deals with the evolution of academic small-scale forestry research in Sweden and the USA from its early focus on timber supply to present-day interest in stewardship objectives, characteristics and attitudes. Aiming at identifying fresh opportunities for research on small-scale forestry, it reflects on the questions that have dominated the literature over the past quarter of a century, the socioeconomic conditions under which those questions arose, and their influence on the evolution of the field. The goal was to explore key drivers for research over the past 25 years and identify emerging research themes, and by that provide insight into what developments may make the research enterprise more fruitful. With some exceptions, it is based on articles in refereed journals and to academic theses covering the time span 1985-2010. It reflects a reappraisal of the subject of the research and corresponding policies. Similar research tendencies are evident in both countries. Research historically focused on the practical problem of efficient production using a weak theoretical foundation. More recently, researchers have focused on understanding diverse motivations and roles that can be played. It is argued that the field of small-scale forestry research is ripe for new multidisciplinary approaches.

However, for current U.S. military operations in hot-arid environments with little or no vegetation, residual applications on portable artificial materials may be a viable alternative. We evaluated bifenthrin residual treatments of U.S. military camouflage netting under hot-arid field conditions in a desert area in southern California exposed to abundant wild Culex tarsalis mosquitoes. We assessed the ability of the treatment to reduce the numbers of mosquitoes penetrating perimeters of netting and reaching CO2-baited mosquito traps. Treated camouflage netting barriers reduced mosquitoes by greater than or equal to 50% for 7-14 days and by 20-35% for 21-28 days compared to untreated barriers. Although reductions may be translated into reductions in risk of exposure to mosquito-borne diseases, we emphasize that barrier treatments should be a component in a suite of insect control measures to be effective.

All of these were purified by affinity chromatography, dialyzed in phosphate buffered saline, and analyzed on SDS-PAGE gels. Collectively, these purified recombinant proteins represent 14.9% of the total M. avium subsp. paratuberculosis proteome. This volume of protein expression and purification has yielded unique observations that may be missed in smaller scale expression and purification projects. For example, the 252 putative membrane proteins predicted by PSORTb analysis, resulted in lower average expression yields (3.51 mg/l culture) than the 176 predicted cytoplasmic proteins (7.27 mg/l culture). A few proteins (MAP0107c, MAP3169c and MAP3640) appear to promote lysis of E. coli since there was a drop in optical density of the growth culture minutes after the inducing agent was added. Certain M. avium subsp. paratuberculosis proteins, when expressed in E. coli changed the color of the column resin or appearance of harvested cell pellets. Finally, 19 proteins showed an absorbance maximum at 260 nm rather than 280 nm that was attributed to binding of nucleic acid during purification. This extensive recombinant protein repository provides a powerful tool for proteome- and genome-scale research of this organism.

We propose a triangular greenness index (TGI), which calculates the area of a triangle with three points: ([lambda]r, Rr), ([lambda]g, Rg), and ([lambda]b, Rb). TGI was correlated with chlorophyll content using a variety of leaf and plot reflectance data. However, indices using the chlorophyll red-edge (710-730 nm) generally had higher correlations. With broad bands, TGI had higher correlations than other indices at leaf and canopy scales. Simulations using a canopy reflectance model indicate an interaction among TGI, leaf area index (LAI) and soil type at low crop LAI, whereas at high crop LAI, TGI was only affected by leaf chlorophyll content. Excess nitrogen fertilizer causes numerous environmental problems, nitrogen management using remote sensing will help balance fertilizer applications with crop nitrogen requirements.

Infested hay debris piles were marked by dusting their surfaces with fluorescent pigments, adults were captured with surrounding grids of Alsynite sticky traps, and specimens were dissected to determine feeding histories and reproductive age, Distances and directions of 3,889 marked specimens indicated males and females dispersed equally and in all directions. Midguts of males and females were equally likely to contain blood-meal remnants. Percentage with blood remnants and percentage of females with yolk increased with distance from mark origin, indicating survival and spread were positively associated with host finding success. A time-integrated diffusion model fit to results from the seven studies indicated 50% of stable fly adults had dispersed beyond 1.6 km of their natal site, but only 5% had dispersed beyond 5.1 km.

New poultry litter incorporation technologies have shown promise at reducing phosphorus losses, but their effectiveness has not been tested in this environmentally sensitive region. This study evaluates subsurface leaching losses of three litter application methods, including surface broadcast, surface broadcast with disking, and subsurface litter incorporation with a novel litter incorporator developed by the USDA Agricultural Research Service. Cube-shaped soil lysimeters (61 x 61 x 61 cm [24 x 24 x 24 in]) were extracted from high phosphorus (P) (Mehlich-3 P is greater than 500 mg kg super(-1)) agricultural soils on the University of Maryland Eastern Shore Research Farm near Princess Anne, Maryland, and were subjected to two rainfall simulation events that were separated by 11 semiweekly soaking-type irrigation events. The average cumulative total phosphorus loss was highest for the subsurface litter incorporation method (0.48 kg ha super(-1) [0.43 lb ac super(-1)]) and was lowest for the no litter control (0.19 kg ha super(-1) [0.17 lb ac super(-1)]). Particulate P loss among manure treatments ranged from 58% to 64% of total P loss. Total phosphorus losses were strongly correlated to total phosphorus concentration in the leachate (coefficient of determination [r super(2)] greater than or equal to 0.84), indicating availability of P in applied litter to be the primary control of P in leachate. Soil properties also impacted P leaching losses, with the soils possessing a higher sand content and having a shallower depth to the sandy subsoil, yielding higher cumulative total P losses (0.64 kg ha super(-1) [0.57 lb ac super(-1)]). Although the subsurface litter incorporator increased total P leaching losses, a concern on the Delmarva Peninsula, opportunity exists to modify the subsurface incorporator design using zone tillage, potentially reducing the leaching losses.

(=Paratrioza) cockerelli (Sulc) (Hemiptera: Triozidae), is a major pest of potato. We examined the role of chemical signals in sex attraction, assessing male and female response to male- and female-produced volatile chemicals. In laboratory olfactometer assays, potato psyllid males were attracted to odorants emitted from live females and from solvent extract of females. These results indicate that the female-produced chemicals responsible for attracting males may be isolated by means of insect extractions. Males were also attracted to volatile chemicals from males and extracts of males, providing the first example of male--male attraction in the Psylloidea. Males exposed simultaneously to odorants from conspecific females and males were preferentially attracted to female odorants, suggesting the presence of a female-specific sex attractant for males. Potato psyllid females avoided volatile chemicals emitted by females and extracts of females and by volatile chemicals emitted by males and extracts of males. Possible explanations for avoidance of conspecifics by females are discussed. This study is the first report of male attraction to volatile chemicals emitted by females and female extracts in the Triozidae and more specifically in the potato psyllid.

Residual analyses and field tests demonstrated that both the pear ester and acetic acid lures were effective for at least 8 wk. The two trap-lure combinations caught a similar number of total moths in an orchard treated with sex pheromone dispensers during short-term trials in 2008. However, the mean catch of female moths was significantly higher and male moths significantly lower in clear traps baited with pear ester and acetic acid versus orange traps baited with pear ester and codlemone. Season-long studies were conducted with these two trap-lure combinations in orchards treated with (n = 6) and without (n = 7) sex pheromone dispensers during 2009. The two trap-lure combinations caught similar numbers of moths in dispenser-treated orchards. In contrast, total catch was significantly higher (>2-fold) in the orange compared with the clear traps in untreated orchards. The clear caught >6-fold more females than the orange trap in both types of orchards. These studies suggest that deploying clear delta traps baited with pear ester and acetic acid can be an effective monitoring tool for female codling moth and an alternative to codlemone-baited traps in sex pheromone-treated orchards.

Yet scientific credibility is essential for effective participation in sociopolitical processes--processes that necessarily involve politics and often result in decisions about land management, conservation, and public policy. All scientists are aware of these processes, many wish to participate, and some wish to advocate for their personal policy preferences. However, scientists who lack impartiality often create the perception of bias, and they can suffer a concomitant loss of credibility. Some policy-makers also have personal preferences for certain policies, and the term normative policies can be used here even though all policies can be viewed as normative in the sense that they involve multiple inputs. Hence, the idea that scientists must provide unbiased information for unbiased application by policy-makers is sometimes wrong. For scientists to be effective participants in sociopolitical processes that lead to conservation policies or related actions, they should inform the public about issues while avoiding direct involvement in policy development and the political considerations this necessarily entails. Scientists should only participate in the decision-making process with impartial information and in their proper role as objective scientists.

Blister rust damage to severely diseased trees reduces reproduction and survival. Severe losses in white pine populations have resulted in site conversions to other species and seriously impacted resource values for timber, wildlife, watershed, recreation, aesthetic and other ecosystem services. In addition to blister rust, other major forest health threats and challenges to sustaining or restoring white pine populations are infestations of other pathogens, insects, fire, management practices that favour other tree species, and climatic change. Recent, large-scale outbreaks of mountain pine beetle have raised concerns for the viability of some white pine populations. In the 1960s, forest disease management for western white pine and sugar pine shifted from Ribes eradication to planting seedlings selected for better survival and resistance to blister rust. Seed orchards for producing improved white pines have been established, but deployment of that improved stock is hampered by a lack of planting opportunities. The inheritance and mechanisms of resistance are best known for western white pine and sugar pine; but new work is extending an understanding of genetics to all the western species of white pine. Current management efforts are focused on locating and protecting individual trees resistant to blister rust and assessing their disease resistance and other adaptive traits. In response to the threats from blister rust, the strategic goal is to sustain or restore viable white pine populations in western forest ecosystems. The four action components of the strategy are: (1) conserve genetic resistance to C. ribicola; (2) reduce the risk of adverse impact in stands currently uninfested; (3) restore and maintain white pines where blister rust is causing impacts and (4) assess and monitor the health and management of white pines. Successful implementation requires long-term support for coordinated efforts of management and research agencies, forest industry and an informed public.

We evaluated 4 registered fungicides on rice seeds (i.e., Allegiance registered FL, Thiram 42-S, Trilex registered , and Vitavax registered 200 preplant seed treatments) and 2 foliar pesticides on sunflower seeds (Cobalt(TM) insecticide and Flock Buster bird repellent) as candidate blackbird repellents.

We observed no concentration-response relationship for the Allegiance seed treatment (P = 0.341) and Flock Buster repellent (P = 0.952). We recommend implementation of supplemental field studies to compare laboratory efficacy, repellency, and chemical residues of effective avian repellents throughout periods of needed crop protection.

Maize, Zea mays L., has been implicated as having a role in the season-long dynamics of tarnished plant bug infestations in cotton. To date, no published information exists describing the quality of maize as a host for tarnished plant bug. No-choice field studies indicated that adult tarnished plant bug females oviposited into maize leaves, tassels, and ears. Laboratory studies showed that first-instar tarnished plant bugs could successfully develop to the adult stage when fed maize silks at the R1 growth stage, tassels before (VT) and during (R1) pollen shed, and milk stage (R3) kernels from the tip and base of the ear. The proportion of nymphs surviving to the adult stage on these tissues was often similar to that of broccoli, Brassica oleracea L. Nymphs did not develop to adults when fed V5 or R1 maize leaves. However, survival of first instars to the adult stage was improved when nymphs fed on tassels with pollen for 6 d and then moved to silks or leaves. Another field study showed that tarnished plant bugs reproduced in maize mainly during the tassel (VE and VT) and the R1-R3 ear growth stages, and a single new generation was produced in maize during these stages. The highest population recorded during the study (24 June 2005) consisted mostly of nymphs and was estimated to be 29,600/ha (12,000/acre). These studies showed that maize is a suitable host for tarnished plant bug reproduction and development, and its production plays a significant role in the population dynamics of the tarnished plant bug in the mid-south.

The adults and nymphs were found primarily in single population peaks in both years, indicating a single new generation was produced during each year, The peak mean numbers of nymphs were 0.61 and 0.84 per drop cloth sample in 1999 and 2001. respectively. Adults peaked at 3.96 (1999) and 3.76 (2001) per sweep net sample (25 sweeps). Tests using laboratory-reared and field-collected tarnished plant bugs resulted in very poor survival of nymphs on 16 different soybean varieties (MG III, one; IV, four; V, nine; VI, two). A large cage (0.06 ha) field test found that the number of nymphs produced on eight soybean varieties after mated adults were released into the cages was lower than could be expected on a suitable host. These results indicated that soybean was a marginal host for tarnished plant bugs. However, the numbers of adults and nymphs found in the commercially produced fields sampled in the study may have been high enough to cause feeding damage to the flowering soybeans. The nature of the damage and its possible economic importance were not determined. Reproduction of tarnished plant bugs in the commercially produced early soybean fields showed that the early soybeans provided tarnished plant bugs with a very abundant host at a time when only wild hosts were previously available.

Oebalus pugnax pugnax (F.) occurs in relatively low numbers, and the predatory stink bug Podisus maculiventris (Say) is commonly found, Limited information is available on natural biological control of these four stink bug species in Georgia corn fields; therefore, a 6-yr study of parasitism and predation of their eggs was initiated in 2003. Naturally occurring stink bug eggs were parasitized by six scelionid species, Trissolcus basalis (Wollaston), T. thyantae Ashmead, T. brochymenae (Ashmead), T. euschisti (Ashmead), Telenomus podisi Ashmead, Telenomus calvus Johnson, and one encyrtid species, Ooencyrtus sp. T. basalis was the most prevalent parasitoid of N. viridula, parasitizing E. servus and P. maculiventris eggs at low levels. T. podisi, the predominant parasitoid species emerging from eggs of E. servus and P. maculiventris, also parasitized O. p. pugnax eggs exclusively and parasitized N. viridula eggs at low levels. T. euschisti and T. thyantae parasitized E. servus egg masses. T. brochymenae parasitized eggs of both E. servus and P. maculiventris. T. calvus parasitized only P. maculiventris eggs. The same species of egg parasitoids that parasitized naturally occurring eggs of N. viridula and E. servus parasitized sentinel eggs of these bugs, except that no T. calvus and Ooencyrtus sp. were obtained from sentinel eggs, and T. thyantae and T. brochymenae emerged from sentinel eggs of N. viridula. Generally, parasitization of an egg mass was either greater than or equal to predation of sentinel eggs of N. viridula and E. servus. However, on some dates in late June and July, predation of sentinel egg masses was numerically approximately twice as high as parasitism. Results indicate stink bug egg parasitoids and predators are significant factors in the natural biological control of stink bugs in corn fields.

Flight profiles included 800-m, 400-m, 200-m, and 100-m flybys (horizontal distance from cliff nest on parallel course), as well as approaches and popouts where helicopters flew toward, or popped out from behind, adult-occupied cliff nests (0 m, horizontal distance). Between 1981 and 2007, during the only 8 years when nesting in the TCA was confirmed by presence of chicks, WPG annually flew 108-2,836 helicopter flights in the same drainages on 10-37 days between 15 December and 15 April, with no effect on early courtship, nest repair, or subsequent nesting success. Total WPG operating days (x[macr] = 62.4) and helicopter hours (x[macr] = 210.6) fluctuated annually but did not increase 1974-2007 (Cox-Stuart trend test, P = 0.371, 0.393, respectively). Apache helicopter testing (227 passes) did not reduce golden eagle nesting success or productivity rates within the same year (t111, 96 = 0.495, 0.782, P = 0.622, 0.436, respectively), or rates of renewed nesting activity the following year, compared with 81-101 non-manipulated nesting territories. We recorded no response during 66% and only watching during 30% of Apache passes at 0-800 m from nesting golden eagles. No other reactions occurred until after hatching when less than or equal to 4 golden eagles accounted for 5 flatten and 3 fly behaviors at 3 nest sites. No responding pairs failed to fledge young because of testing. Limited fly responses suggested helicopters only precipitated an imminent departure, rather than causing startled, avoidance reactions. Responsiveness between test weeks 1 and 2 decreased ( chi 22 = 32.167, P less than or equal to 0.001). Apache helicopters were twice as loud as WPG helicopters at comparable distances. Sound decreased with distance, most rapidly when flights were perpendicular to cliffs or ridges. Eagle ambient behaviors and watching the helicopter occurred randomly throughout recorded sound levels during helicopter testing (76.7-108.8 decibels, unweighted). Much helicopter sound energy is below golden eagles' auditory threshold, thus reducing potential impacts. Neither our observations nor our testing indicated special management restrictions are required for helicopters flying near nesting golden eagles in northern Utah. Our results underscore the necessity for circumstance-specific research, as well as enlightened resource management to accommodate unexpected results.

We evaluated the ability of wild-caught deer to jump progressively taller fences and documented deterrence rates of 0% for fences less than or equal to 1.5 m followed by increasing deterrence rates of 14% at 1.8 m, 85% at 2.1 m, and 100% at 2.4 m. We documented 100% deterrence rates during 5 additional experiments with different deer and the test fence at 2.4 m, a common height of fences at captive deer facilities. Our results will be valuable to those managing spread of wildlife diseases, deer-vehicle collisions, and agricultural damage.

We compare grapefruit, Citrus paradisi Macfayden, naturally infested by Mexican fruit fly, Anastrepha ludens (Loew), via oviposition until larvae reached the late third instar versus insertion of diet-reared third instars into holes made in grapefruits 24 h before irradiation; the latter technique has been used in other studies. Both infestation techniques resulted in statistically indistinguishable results, indicating that insertion of diet-reared third instar Mexican fruit fly into holes bored into grapefruit and subsequently sealed 24 h before irradiation would adequately represent natural infestation and could be used to develop a radiation phytosanitary treatment of the insect in grapefruit when prevention of adult emergence is used as the measure of efficacy. Nevertheless, it may not be advisable to extend this conclusion to other fruit fly/fruit combinations without doing appropriate comparison studies. Dissection of puparia from nonirradiated control insects that failed to emerge as adults showed a relatively even distribution of mortality among the developmental stages within the puparium. In contrast, dissection of puparia from irradiated third instars that did not emerge as adults revealed a sharp attenuation in development from cryptocephalic to phanerocephalic pupae demonstrating this transition to be the developmental step most affected by radiation.

However, these omnivores are also facultative predators on a wide variety of insects. This study was conducted to quantify and compare herbivory and carnivory exhibited among different lifestages of these two insect pests. The feeding activity of a total of 422 individuals was observed for 1 h each in feeding arenas containing a cotton leaf disk and copious amounts of the sweetpotato whitefly, Bemisia tabaci (Gennadius) (Hemiptera: Aleyrodidae) eggs, nymphs and adults. The L. hesperus and L. lineolaris lifestages examined included adults and 3rd, 4th and 5th instar nymphs. Plant feeding occupied the majority of both species' time budget, regardless of the species or lifestage examined. There was a tendency for L. lineolaris lifestages to feed more often and for longer duration on plant tissue than L. hesperus. All lifestages of both species rarely fed on B. tabaci, but when they did, they preferred nymphs > adults > eggs. There were only a few cases where there were significant differences in predation rates and prey handling times exhibited among lifestages and between species, but juvenile L. hesperus tended to be more predaceous than juvenile L. lineolaris on whitefly nymphs and adults and 5thinstar and adult L. lineolaris were significantly more herbaceous than their L. hesperus counterparts. In addition, the younger individuals of both species tended to have greater prey handling times than their older counterparts. The significance of these findings is discussed.

A new genetic transformation system for the organism would greatly facilitate the biological study and molecular engineering of this organism. We report here a versatile gene expression method for the genetic engineering of R. eutropha. This method, based on a simplified electroporation protocol, uses a recombinant plasmid, pBS29-P2, containing a Pseudomonas syringae promoter (P2) and two antibiotic-resistance markers (i.e., genes coding for kanamycin (Km)- and tetracycline (Tc)-resistance). Using this method, we successfully achieved transformation of wild-type R. eutropha and its poly(hydroxyalkanoate)-negative mutant, R. eutropha PHBa4, with various pBS29-P2-based recombinants. A transformation frequency as high as 4A-103 Km-resistance colonies/I14g DNA was obtained per electroporation experiment. We further demonstrated the successful expression of a heterologous gene coding for green-fluorescent-protein by fluorescence measurement. In addition, our results indicated the expression of a truncated but active Streptomyces coelicolor a-galactosidase in R. eutropha.

Crop water stress may alter canopy temperature, the energy balance, transpiration, photosynthesis, canopy water use efficiency, and crop yield. The objective of this study was to calculate the Crop Water Stress Index (CWSI) from canopy temperature and energy balance measurements and evaluate the utility of CWSI to quantify water stress by comparing CWSI to latent heat and carbon dioxide (CO2) flux measurements over canopies of winter wheat (Triticum aestivum L.) and summer maize (Zea mays L.). The experiment was conducted at the Yucheng Integrated Agricultural Experimental Station of the Chinese Academy of Sciences from 2003 to 2005. Latent heat and CO2 fluxes (by eddy covariance), canopy and air temperature, relative humidity, net radiation, wind speed, and soil heat flux were averaged at half-hour intervals. Leaf area index and crop height were measured every 7 days. CWSI was calculated from measured canopy-air temperature differences using the Jackson method. Under high net radiation conditions (greater than 500Wm super(-2)), calculated values of minimum canopy-air temperature differences were similar to previously published empirically determined non-water-stressed baselines. Valid measures of CWSI were only obtained when canopy closure minimized the influence of viewed soil on infrared canopy temperature measurements (leaf area index was greater than 2.5m super(2) m super(-2)). Wheat and maize latent heat flux and canopy CO2 flux generally decreased linearly with increases in CWSI when net radiation levels were greater than 300Wm super(-2). The responses of latent heat flux and CO2 flux to CWSI did not demonstrate a consistent relationship in wheat that would recommend it as a reliable water stress quantification tool. The responses of latent heat flux and CO2 flux to CWSI were more consistent in maize, suggesting that CWSI could be useful in identifying and quantifying water stress conditions when net radiation was greater than 300Wm super(-2). The results suggest that CWSI calculated by the Jackson method under varying solar radiation and wind speed conditions may be used for irrigation scheduling and agricultural water management of maize in irrigated agricultural regions, such as the North China Plain.

A two-year experiment with four irrigation levels based on crop growth stages was used to calibrate and validate RZWQM2, a hybrid model that combines the Root Zone Water Quality Model (RZWQM) and DSSAT4.0. The calibrated model was then used to investigate various irrigation strategies for high yield and water use efficiency (WUE) using weather data from 1961 to 1999. The model simulated soil moisture, crop yield, above-ground biomass and WUE in responses to irrigation schedules well, with root mean square errors (RMSEs) of 0.029cm3 cma degree 3, 0.59Mghaa degree 1, 2.05Mghaa degree 1, and 0.19kgma degree 3, respectively, for wheat; and 0.027cm3 cma degree 3, 0.71Mghaa degree 1, 1.51Mghaa degree 1 and 0.35kgma degree 3, respectively, for maize. WUE increased with the amount of irrigation applied during the dry growing season of 2001-2002, but was less sensitive to irrigation during the wet season of 2002-2003. Long-term simulation using weather data from 1961 to 1999 showed that initial soil water at planting was adequate (at 82% of crop available water) for wheat establishment due to the high rainfall during the previous maize season. Preseason irrigation for wheat commonly practiced by local farmers should be postponed to the most sensitive growth stage (stem extension) for higher yield and WUE in the area. Preseason irrigation for maize is needed in 40% of the years. With limited irrigation available (100, 150, 200, or 250mm per year), 80% of the water allocated to the critical wheat growth stages and 20% applied at maize planting achieved the highest WUE and the least water drainage overall for the two crops.

The objective of this study was to investigate representative groups of native microflora and the distribution, growth, and inactivation of experimentally-inoculatedSalmonellaSaintpaul on jalapeno peppers. Two genetically modified strains ofSalm.Saintpaul producing either green- or red-fluorescent protein were constructed and used in the study. Microbiological analyses showed that jalapeno peppers contained an average of 5.6 log units of total aerobic count and 3.5, 1.8, and 1.9 log units, respectively, of enterobacteriaceae, lactic acid bacteria, and yeast/mold per gram of tissue. Strains typical ofPseudomonasaccounted for 8.3% of total aerobic count, and 0.2% of which exhibited pectolytic activity. On inoculated peppers, a vast majority (>90%) ofSalm.Saintpaul was recovered from stem/calyx and only a small proportion recovered from fleshy pods. Growth ofSalm.Saintpaul on peppers was indicated by an increase in the population of 3 log units after incubation of samples at 20 degree C for 48 h. FluorescentSalm.Saintpaul aggregates could be readily detected on stem/calyx using stereofluorescence imaging microscopy and scanning electron microscopy. Data presented showed thatSalm.Saintpaul could survive for at least 8 wk on peppers stored at 4 degree C. Immersion of inoculated peppers in 200 ppm of sodium hypochlorite, acidified sodium chlorite, or peroxy acetic acid for 10 min could reduce the number ofSalm.Saintpaul on stem/calyx by 1.5 to 1.7 and that on flesh by 2.1 to 2.4 log units. Practical Application: Consumption ofSalmonella-contaminated jalapeno peppers has been implicated in foodborne illness outbreaks. The vast majority ofSalmonellaSaintpaul recovered from inoculated jalapeno peppers (>90%) was from stem/calyx.Salmonellaincreased by 3 log units during storage at 68 degree F (20 degree C) for 48 h.Salmonellacould survive for at least 8 wk on peppers stored at 4 degree C. Immersion of inoculated peppers in 200 ppm of sodium hypochlorite, acidified sodium chlorite, or peroxyacetic acid for 10 min reducedSalmonellaon stem/calyx by 1.5 to 1.7 log units, compared with reductions of 2.1 to 2.4 log units on flesh. These results highlight the need to consider the stem/calyx as the most likely area for contamination of jalapeno peppers, and to process this commodity accordingly to minimize exposure and cross-contaminations.

The objective of this research was to investigate the impact of mechanical shear on the survival ofListeria monocytogeneson surfaces. Mechanical shear created by slicing a model food was explored to investigate the viability ofL. monocytogenes. Cell injury/death was readily demonstrated in fluorescence images by confocal microscopy in which the live and dead cells were fluorescently stained green and red, respectively, with a viability dye kit. Images showed that a large percentage of dead cells appeared after slicing, and they were readily transferred from the slicer blade onto the surfaces of sliced agar, indicating that surface shear may cause the lethal effect onL. monocytogenes. Surface transfer results also showed that viable cell counts on agar slices (in a slicing series) followed a consistently decreasing pattern. The cell counts initially at 5 to 6.5 log CFU/slice (slices 1 to 6), decreased to 3 to 4 log CFU/slice (slices 8 to 30), then to 2 to 3 log CFU/slice (slices 31 to 40), and counts would be expected to further decrease if slicing continued. The overall cell recovery (survival) ratio was about 2% to 3% compared to the initial 8.4 log CFU/blade on a 10 cm2 edge area. The impact of shear on microbial viability during slicing may contribute 99% of viable cell count reduction. This study provides clear evidence that surface shear can kill foodborne pathogens and reduce cross-contamination. The lethal effects of surface shear may further enhance food safety.

AN - 759309663; 13218050 AB - We evaluated whether growth rates of six fish species correlated with PCB concentrations in a moderately-to-heavily polluted freshwater ecosystem. Using a large dataset (n=984 individuals), and after accounting for growth effects related to fish age, habitat, sex, and lipids, growth correlated significantly, but positively with lipid-corrected PCB concentrations for 4 of 6 species. Remaining species showed no correlations between growth and PCBs. Comparisons with regional, lentic growth averages for four species confirmed growth was on par and in three of four cases higher than regional averages in the PCB-polluted ecosystem. We conclude that for these species, at the range of concentrations examined, these PCBs do not exert negative impacts on growth. Rather, factors often cited as influential to growth were also driving growth trends in this study. Future studies that evaluate whether pollution affects growth must account for major growth drivers prior to attributing growth differentials to pollution alone. Growth rates of fish in a polluted ecosystem do not correlate negatively with PCB concentrations.

Mean leaf strength for plants collected within California was 1.72 Newtons (N) and ranged from 0.36 to 6.32N, based on 1170 individual determinations. For leaves collected from 30 plants within four states between July 11 and 20, 2007, mean leaf strength was 1.58N based on 936 determinations. Values ranged from 0.24 to 4.90N. Overall, leaf strength showed statistically significant changes depending on the sampling date, sampling location, type of leaf sampled, and position within the leaf where the measurement was taken. In general leaf strength was greater near the base of the leaf and decreased with distance away from the base; leaf strength changed as the growing season progressed; and first year leaves had leaf strength values about 25% greater than leaves produced on stems >1-year old. This represents two of the three age categories of leaves which may be present on giant reed at any one time. Stem strength and stem wall thickness were strongly correlated (Kendall's Tau b=0.92, P<0.0001, N=26). Linear regression indicated that mean stem strength decreased by approximately 6.8% (95% confidence limits 5.8-7.7%) from one node to the successive node progressing from the stem base to the shoot tip. These results imply that the ability of biological control agents to damage A. donax leaves may not be the same across the locations this plant occurs or at all times during the growing season within a given location.

The 5- to 10-m-deep vadose zone is characterized by shallow soils (1 m), microrelief (mounds and plains), and large soil pockets within the limestone matrix were also identified. Main sources of GPR signal attenuation were suspected to be the higher clay and water contents of soil material contained in underlying cavities. As a noninvasive tool, GPR can help to determine properties of the limestone and its dissolution features that are critical to vadose zone-forest interactions.

Salmonella and Staphylococus aureus are prevalent among pathogens which cause foodborne illness. Ultraviolet light (UV-C) (254 nm) is a U.S. Food and Drug Administration (FDA)-approved intervention technology that can inactivate foodborne pathogens on frankfurter and precooked sausage surfaces. Potassium lactate, sodium diacetate and lauric arginate ester are U.S. FDA-approved antimicrobials that can inactivate and inhibit the growth of foodborne pathogens during refrigerated storage. UV-C light, when used in combination with the three antimicrobials, inactivated 2.32-2.80 log of the pathogens, which was more effective than either process used individually as determined by analysis of variance (n = 6,P < 0.05). During 12 weeks of refrigerated storage (10C), the use of UV-C in combination with the 3 antimicrobials was found to be very effective, with 3.6-4.1 log of the three pathogens being inactivated by the end of the storage period. UV-C and antimicrobials had no impact on frankfurter color or texture. The combinatorial use of UV-C and antimicrobials was found to be an effective hurdle against pathogen survival and proliferation.PRACTICAL APPLICATIONS JF - Journal of Food Safety AU - Sommers, Christopher H AU - SCULLEN, OJOSEPH AU - Sites, Joseph E AD - 1Food Safety Intervention Technologies Eastern Regional Research Center Agricultural Research Service United States Department of Agriculture 600 East Mermaid Lane, Wyndmoor, PA 19038 Y1 - 2010/08// PY - 2010 DA - Aug 2010 SP - 666 EP - 678 PB - Wiley-Blackwell, 111 River Street Hoboken NJ 07030-5774 USA VL - 30 IS - 3 SN - 0149-6085, 0149-6085 KW - Microbiology Abstracts B: Bacteriology; Health & Safety Science Abstracts KW - inactivation KW - Survival KW - food-borne diseases KW - Cold storage KW - Sodium diacetate KW - U.V. radiation KW - Frankfurters KW - intervention KW - meat KW - Drugs KW - Potassium KW - LIGHT protein KW - outbreaks KW - Pathogens KW - Food contamination KW - Esters KW - potassium lactate KW - Color KW - Antimicrobial agents KW - Light effects KW - Sodium KW - Storage KW - Meat KW - USA KW - Sausages KW - survival KW - Contaminants KW - Salmonella KW - antimicrobial agents KW - Technology KW - J 02400:Human Diseases KW - H 4000:Food and Drugs UR - http://libproxy.lib.unc.edu/login?url=http://search.proquest.com/docview/754897321?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=Journal+of+Food+Safety&rft.atitle=INACTIVATION+OF+FOODBORNE+PATHOGENS+ON+FRANKFURTERS+USING+ULTRAVIOLET+LIGHT+AND+GRAS+ANTIMICROBIALS&rft.au=Sommers%2C+Christopher+H%3BSCULLEN%2C+OJOSEPH%3BSites%2C+Joseph+E&rft.aulast=Sommers&rft.aufirst=Christopher&rft.date=2010-08-01&rft.volume=30&rft.issue=3&rft.spage=666&rft.isbn=&rft.btitle=&rft.title=Journal+of+Food+Safety&rft.issn=01496085&rft_id=info:doi/10.1111%2Fj.1745-4565.2010.00232.x LA - English DB - ProQuest Environmental Science Collection N1 - Date revised - 2010-09-01 N1 - Number of references - 35 N1 - Last updated - 2015-03-19 N1 - SubjectsTermNotLitGenreText - Survival; LIGHT protein; Pathogens; Esters; potassium lactate; Light effects; Antimicrobial agents; Color; Meat; Cold storage; U.V. radiation; Sodium diacetate; Frankfurters; Sausages; Contaminants; inactivation; Potassium; outbreaks; Food contamination; food-borne diseases; Storage; Sodium; intervention; meat; survival; Drugs; antimicrobial agents; Technology; Salmonella; USA DO - http://dx.doi.org/10.1111/j.1745-4565.2010.00232.x ER - TY - JOUR T1 - BEHAVIOR OF AVIRULENT YERSINIA PESTIS IN LIQUID WHOLE EGG AS AFFECTED BY STORAGE TEMPERATURE, ANTIMICROBIALS AND THERMAL PASTEURIZATION AN - 754897306; 13529030 AB - ABSTRACT: Yersinia spp. are psychrotrophic bacteria capable of growth at temperatures as low as -2C, known to contaminate shell eggs and liquid eggs in the U.S.A. and South America. A study was performed to determine the thermal sensitivity of avirulent Yersinia pestis in liquid whole egg (LWE), evaluate the growth pattern of the bacterium in LWE at temperatures of 4-22 degree C and assess the ability of 10 antimicrobial compounds to inhibit the growth of attenuated Y. pestis in LWE. The estimated decimal reduction values of avirulent Y. pestis in LWE at 54 degree C (D54) were 1.39-1.58 min, and D60 values were 13.8 and 11.4 s by the addition of 0 and 965 IU of nisin (MP Biomedicals, LLC, Solon, OH), respectively. Low molecular weight chitosan (0.5%) and an activated lactoperoxidase system (2.18 U/mL) were ineffective at inhibiting growth of Y. pestis, while 500 IU/mL of nisin inhibited populations by up to 1 log cfu/mL at 4, 10 and 15 degree C when compared with the control. Allyl isothiocyanate, diacetyl, diethyl dicarbonate, ethylene diaminetetraacetic acid, methylparaben, monolaurin and benzoyl peroxide inhibited the growth of attenuated Y. pestis when added at high levels.

In this study, seed zones were developed for mountain brome (Bromus carinatus Hook. & Arn.) in the Blue Mountains of northeastern Oregon and adjoining Washington. Plants from 148 Blue Mountain seed source locations were evaluated in common-garden studies at two contrasting test sites. Data on phenology, morphology, and production were collected over two growing seasons. Plant traits varied significantly and were frequently correlated with annual precipitation and annual maximum temperature at seed source locations (P < 0.05). Plants from warmer locations generally had higher dry matter production, longer leaves, wider crowns, denser foliage, and greater plant height than those from cooler locations. Regression models of environmental variables with the first two principal components (PC 1 and PC 2) explained 46% and 40% of the total variation, respectively. Maps of PC 1 and PC 2 generally corresponded to elevation, temperature, and precipitation gradients. The regression models developed from PC 1 and PC 2 and environmental variables were used to map seed transfer zones. These maps will be useful in selecting mountain brome seed sources for habitat restoration in the Blue Mountains.Original Abstract: Les zones de transfert des semences assurent qu'un germoplasme selectionne pour la restauration convient et demeure durable dans divers environnements. Dans cette etude, les auteurs ont developpe des zones d'ensemencement pour le brome (Bromus carinatus Hook. & Arn.) des Blue Mountains du nord-est de l'Oregon et de l'etat de Washington voisin. Dans des jardins communs situes sur deux sites fortement contrastes, ils ont evalue des plants provenant de 148 provenances de semences recoltees dans les Blue Mountains. Ils ont reuni les donnees sur la phenologie, la morphologie et la productivite au cours de deux saisons de croissance. Les caracteres des plantes varient significativement et montrent souvent des correlations avec la precipitation annuelle et les temperatures maximales annuelles prevalant sur les sites de provenance des semences. Les plantes venant des localites plus chaudes montrent generalement une productivite en matiere seche plus grande, des feuilles plus longues, des cimes plus larges, un feuillage plus dense et des plants plus hauts, que ceux provenant de localites plus froides. Les modeles de regression des variables environnementales portant sur les deux premieres composantes principales (PC 1 et PC 2) expliquent respectivement 46 % et 40 % de la variation totale. Les cartes des PC 1 et PC 2 correspondent generalement aux gradients d'elevation, de temperature et de precipitation. Les auteurs ont utilise les modeles de regression developpes a partir des PC 1 et PC 2 avec les variables environnementales pour cartographier les zones de transfert des sources de semences destinees a la restauration des habitats dans les Blue Mountains.

In order to count towards the goal, biofuels must achieve greenhouse gas savings as high as 60 per cent after 2017. Regarding Brazil's leading biofuels, the directive assigns a default savings level of 71 per cent to sugarcane-based bioethanol and 31 per cent to soybean-based biodiesel. Biofuels obtained from biomass grown on lands of high carbon stock or high biodiversity value would not qualify as sustainable under the directive, based on the land's status in January 2008. However, the directive leaves open the possibility of converting some savannahs and open forests to biomass production. Amendments reported by the European Parliament's Committee on Industry, Research and Energy (ITRE) but not incorporated within the directive would have called on second-generation biofuels and vehicles powered by renewable sources of electricity or hydrogen to supply at least 40 per cent of the 10 per cent goal, and they would have treated all of Brazil's savannahs and many of its open forests as unsustainable places for biomass production.Original Abstract: Exigences de durabilite environnementale de l'Union europeenne et exportations bresiliennes de biocarburantsCet article examine l'objectif de l'Union europeenne (UE) de tirer des biocarburants 10 pour cent de l'energie utilisee pour le transport d'ici 2020 et il considere comment les criteres de durabilite environnementale de la Directive sur l'energie renouvelable de l'UE pourraient s'appliquer au Bresil. Pour contribuer a cet objectif, les biocarburants doivent permettre de reduire les emissions de gaz a effet de serre a hauteur d'au mois 60 pour cent apres 2017. En ce qui concerne les principaux biocarburants produits par le Bresil, la directive attribue des niveaux de reduction par defaut de 71 pour cent pour le bioethanol derive de la canne a sucre et 31 pour cent pour le biodiesel a base de soja. Les biocarburants obtenus a partir de biomasse provenant de terres a fort stockage de carbone ou a forte valeur de biodiversite, selon la classification des terres de janvier 2008, ne seraient pas consideres comme durables dans le cadre de la directive. Cependant, la directive donne la possibilite de convertir certaines savanes et forets ouvertes en vue de produire de la biomasse. Des amendements rapportes par la Commission de l'industrie, de la recherche et de l'energie du Parlement europeen (ITRE) mais non inclus dans la directive auraient demandea ce que les biocarburants de deuxieme generation et les vehicules fonctionnant avec des sources durables d'electricite ou d'hydrogene fournissent au moins 40 pour cent des 10 pour cent vises. Ils auraient aussi considere que l'ensemble des savanes du Bresil ainsi que la plupart de ses forets ouvertes n'etaient pas des endroits durables pour la production de biomasse. Die EU-Anforderungen fuer oekologische Nachhaltigkeit und Biokraftstoffexporte aus BrasilienDieser Beitrag untersucht das Ziel der EU, bis 2020 zehn Prozent der Verkehrskraftstoffe durch Biokraftstoffe zu ersetzen, und wie die Kriterien der oekologischen Nachhaltigkeit aus der neuen EU-Richtlinie zur Verwendung von erneuerbaren Energien moeglicherweise auf Brasilien zutreffen. Nach 2017 muessen Biokraftstoffe eine Senkung der Treibhausgasemissionen um mindestens 60 Prozent erreichen, um als positiver Zielbeitrag angesehen zu werden. Fuer die wichtigsten brasilianischen Biokraftstoffe gibt die Richtlinie als Standardwert Einsparungen von 71 Prozent fuer aus Zuckerrohr hergestelltes Bioethanol sowie 31 Prozent fuer aus Sojabohnen hergestellten Biodiesel an. Biokraftstoffe aus Biomasse, die auf Boeden mit hohem Kohlenstoffgehalt oder grosser Biodiversitaet erzeugt wurde, wuerden im Rahmen der Richtlinie nicht als nachhaltig gelten. Massgeblich ist hierfuer der Bodenstatus vom Januar 2008. Die Richtlinie haelt jedoch die Moeglichkeit offen, einige Savannen und offene Waelder zur Erzeugung von Biomasse umzuwidmen. Aenderungsantraege, die vom Ausschuss fuer Industrie, Forschung und Energie im Europaparlament gewuenscht, jedoch nicht in die Richtlinie aufgenommen wurden, haetten verlangt, dass wenigstens 40 Prozent der angestrebten zehn Prozent durch Biokraftstoffe der zweiten Generation sowie den Einsatz von erneuerbaren Stromquellen oder Wasserstoff zum Antrieb von Fahrzeugen erreicht werden. Zudem wuerden dann alle Savannen und viele offene Waelder in Brasilien im Hinblick auf die Erzeugung von Biomasse als nicht nachhaltig angesehen.

In total, 230,908 individuals were shipped to California and 202,328 were released in the field, a 12.4% mortality rate from shipment to release. Thirteen sample sites were located in nine counties; 11 sites received parasitoids from September 2008 to January 2009 (range: 3114-55,826 per site). Olive fruit fly population density, as measured by adult traps, varied greatly among sites and sample dates - ranging from 10,000 fruit collected, across all sites and sample dates, showed parasitism ranging from 0-17%. Laboratory studies were conducted to determine the fitness of P. humilis reared on irradiated and fertile C. capitata. Results showed no difference in parental size, progeny produced during a 48 h period, or the number female: male offspring produced; there were significantly fewer eggs in the dissected ovaries of irradiated than fertile female P. humilis. Continuous flight in different air temperatures and air speeds for female and male parasitoids showed no difference in female or male P. humilis reared on irradiated C. capitata or female P. humilis reared on fertile olive fruit fly. Results are discussed with respect to the establishment and effective use of P. humilis for control of olive fruit fly in California's varying climatic regions where olives are grown.

False oleander scale, P. cockerelli, coconut scale, Aspidiotus destructor, cycad scale, Aulacaspis yasumatsui, greenhouse whitefly, Trialeurodes vaporariorum, green scale, Coccus viridis, and long-tailed mealybug, Pseudococcus longispinus were tested in quarantine using traditional no-choice tests and examined for wasp emergence. The Hawaiian endemic palm scale, Colobopyga pritchardiae was also tested using no-choice tests and evaluated using species-specific molecular markers. All tests used unexposed non-target cohorts and no-choice exposure of white peach scale to the parasitoid as controls. None of the non-target exotic species yielded wasp emergence, and exposure to wasps had no effect on the mortality of the non-target species examined. Molecular tests with the endemic palm scale showed no evidence of parasitism by E. diaspidicola. These results strongly support that E. diaspidicola has a narrow host range and that its release in Hawaii will have negligible risk of non-target effects.

Resistance was overcome by natural phenolic chemosensitizing agents targeting the oxidative stress-response pathway. These agents also augmented effectiveness of the fungicide, kresoxim-methyl. Results indicated that alkyl gallates target mitochondrial respiration and-or its antioxidation system. Fungal mitochondrial superoxide dismutase (Mn-SOD) plays a protective role against alkyl gallates.Conclusions: Natural chemosensitizing agents targeting the oxidative stress-response system, such as Mn-SOD, can synergize commercial fungicides.Significance and Impact of the Study: Redox-active compounds can serve as potent chemosensitizing agents to overcome resistance and lower effective dosages of fungicides.

Furfural inhibits efficient ethanol production by yeast, particularly when the carbon source is acid-treated lignocellulose, which contains furfural at a relatively high concentration. NADPH is Ari1p's best known hydride donor. Here we report the stereochemistry of the hydride transfer step, determined by using (4R)-[4-2H]NADPD and (4S)-[4-2H]NADPD and unlabeled furfural in Ari1p-catalyzed reactions and following the deuterium atom into products 2-furanmethanol or NADP+. Analysis of the products demonstrates unambiguously that Ari1p directs hydride transfer from the si face of NADPH to the re face of furfural. The singular orientation of substrates enables construction of a model of the Michaelis complex in the Ari1p active site. The model reveals hydrophobic residues near the furfural binding site that, upon mutation, may increase specificity for furfural and enhance enzyme performance. Using (4S)-[4-2H]NADPD and NADPH as substrates, primary deuterium kinetic isotope effects of 2.2 and 2.5 were determined for the steady-state parameters kcatNADPH and kcat/KmNADPH, respectively, indicating that hydride transfer is partially rate limiting to catalysis.

L. americanus' AN - 754536132; 13242908 AB - Huanglongbing, or citrus greening, threatens the global citrus industry. The presumptive pathogens, 'Candidatus Liberibacter asiaticus' and 'Ca. L. americanus' can be transferred from citrus to more easily studied experimental hosts by using holoparasitic dodder plants. However, the interaction between 'Candidatus Liberibacter' spp. and the dodder has not been studied. We combined quantitative polymerase chain reaction with electron microscopy to show that only 65% of tendrils of Cuscuta indecora grown on 'Ca. Liberibacter' spp.-infected host plants had detectable levels of the pathogen. Among tendrils that were colonized by Liberibacter in at least one 2 cm segment, most were not colonized in all segments. Furthermore, the estimated population levels of the pathogen present in serial 2 cm segments of dodder tendrils varied widely and without any consistent pattern. Thus, there was generally not a concentration gradient of the pathogen from the source plant towards the recipient and populations of the pathogen were sometimes found in the distal segments of the dodder plant but not in the proximal or middle segments. Populations of the pathogens ranged from 2 x 10 super(2) to 3.0 x 10 super(8) cells per 2 cm segment. On a fresh weight basis, populations as high as 1.4 x 10 super(10) cells per g of tissue were observed demonstrating that 'Ca. Liberibacter' spp. multiplies well in Cuscuta indecora. However, 55% of individual stem segments did not contain detectable levels of the pathogen, consistent with a pattern of nonuniform colonization similar to that observed in the much more anatomically complex citrus tree. Colonization of dodder by the pathogen is also nonuniform at the ultrastractural level, with adjacent phloem vessel elements being completely full of the pathogen or free of the pathogen. We also observed bacteria in the phloem vessels that belonged to two distinct size classes based on the diameters of cross sections of cells. In other sections from the same tendrils we observed single bacterial cells that were apparently in the process of differentiating between the large and round forms to the long and thin forms (or vice versa). The process controlling this morphological differentiation of the pathogen is not known. The highly reduced and simplified anatomy of the dodder plant as well as its rapid growth rate compared with citrus, and the ability of the plant to support multiplication of the pathogen to high levels, makes it an interesting host plant for further studies of host-pathogen interactions.

There is a U.S. record from Maryland (2); in 1947, Peterson (4) stated that this species had never been found blighted in its natural habitat, although in 1960 it was listed as a host of P. infestans in New York (1). The A2 mating type has not been reported on this host. On 2 July, 2009, leaf lesions similar to those of P. infestans on potato were found on wild S. dulcamara at Riverhead, NY. The plant was growing in a home garden within 10 m of potato and tomato plants infected with P. infestans. When two infected leaves of S. dulcamara were incubated for 24 h under high humidity, a pathogen growth developed around the lesion margins that was characterized by hyaline mycelium bearing lemon-shaped sporangia that released motile zoospores after chilling in water, which is consistent with P. infestans. The caducous and limoniform to ovoid sporangia were 39 to 50 km (average 45 km) x 26 to 28 km (average 27 km) with a length/breadth ratio of 1.66. No oospores were observed. Three isolates were obtained from this plant during July 2009. Growth on rye agar was indistinguishable from that of local tomato isolates of P. infestans. Detached leaflets of S. dulcamara and S. tuberosum, inoculated with the woody nightshade isolates and kept in a humid chamber, became infected and developed profuse sporulation within 5 days. The pathogen isolated was confirmed as P. infestans by morphological, biochemical, and molecular characteristics. Inoculations of attached leaves of potted S. dulcamara plants resulted in necrotic lesions with many sporangia; sporulation also developed on inoculated, attached, and detached tomato leaves. P. infestans was reisolated and identity confirmed as before. The three isolates were A2 mating type, metalaxyl-resistant, mitochondrial haplotype Ia. All were glucose-6-phosphate isomerase 100/122 and peptidase 100/100, as confirmed with single-spore isolates. RG57 fingerprint analysis confirmed that isolates from woody nightshade, tomato, and potato obtained from the same and nearby sites were identical. Although P. infestans in the United States belongs to the new population, which may infect a wider host range than the old US-1 clonal lineage, S. dulcamara infections have only been found when late blight is already widespread in neighboring fields and there is no evidence to suggest that woody nightshade acts as an overwintering host in the United States.

The disease is caused primarily by the fungal pathogen Phomopsis longicolla. Aggressiveness of isolates of P. longicolla from soybean and other Phomopsis spp. from other hosts were compared by inoculating 2-week-old soybean plants of cv. Williams 82. There were significant (P , 0.0001) differences among isolates based on stem length and stem lesion length. The P. longicolla soybean isolate PL16, from Mississippi, caused the shortest stem length while the non-soybean isolate P9, from Illinois, caused the greatest stem lesion length. The type isolate of P. longicolla, PL31 (Fau 600), was one of the 3 most aggressive isolates among all 48 isolates tested. The velvetleaf isolate P9 was the most aggressive among 13 isolates from non-soybean hosts. This study provided the first evaluation of aggressiveness of P. longicolla isolates from different geographic origins and the first demonstration that Phomopsis spp. isolated from cantaloupe, eggplant, and watermelon infected soybean. Knowledge about the variability of the pathogen is important for selecting isolates for breeding soybean lines with broad-based resistance to Phomopsis seed decay.

Inoculation experiments were conducted to compare the aggressiveness of the three Phytophthora spp. on stems, leaf disks, and roots of European beech and common lilac (Syringa vulgaris) seedlings. Isolates were obtained from bleeding cankers on European beech from five cities in New York (Albany, Ithaca, Oyster Bay, Plainview, and Rochester) and from a bleeding canker on sugar maple in Ithaca, NY. Stems were inoculated with colonized agar plugs, leaf disks with a zoospore suspension, and roots via infested soil at three inoculum levels. All organs of inoculated beech and lilac developed disease except for lilac roots inoculated with zoospores of P. cactorum. Disease incidence, severity, and plant survival were dependent on isolate and were also influenced by the tissue inoculated and host. Isolates of P. cactorum were the least aggressive and caused less necrosis than isolates of P. citricola I and P. plurivora. Results emphasize the utility of stem and root inoculation for evaluation of this canker disease and underscore critical differences in species aggressiveness.

The genes encoding these functions were identified in Pseudomonas syringae pv. syringae B728a based on similarity to the lambda Red Exo/Beta and RecET proteins encoded by the lambda and Rac bacteriophages of Escherichia coli. The ability of the pseudomonad-encoded proteins to promote recombination was tested in P. syringae pv. tomato DC3000 using a quantitative assay based on recombination frequency. The results show that the Pseudomonas RecT homolog is sufficient to promote recombination of single-stranded DNA oligonucleotides and that efficient recombination of double-stranded DNA requires the expression of both the RecT and RecE homologs. Additionally, we illustrate the utility of this recombineering system to make targeted gene disruptions in the P. syringae chromosome.

Unlike their European counterparts, little is known about the basic ecology of managed grasslands in this region. During an 8-year survey of 28 farms across the northeastern United States, we sampled the vegetation on 95 grazed plots, identifying 310 plant species, and collected data on topography, climate and soils. Landscape structure data were obtained from the National Land Cover Data (NLCD) 2001 for six radii (250-2,000m) surrounding each site. The 500-m radius was most strongly related to plant community composition. Planned species composition was related only to site factors, while associated species were influenced by both site factors and landscape pattern. Species richness was unrelated to landscape structure for either group. Differing management effects on planned and associated species may explain the variation in their responses. Managed grasslands are a critical part of the interconnected landscape of the northeastern United States, and both affect and are affected by their surroundings.

Whitefly abundance data were collected under both greenhouse (caged and uncaged) and field conditions. Consistently, a reflective mulch (also called silver or metallic) treatment resulted in a lower incidence of adult whiteflies as compared with a standard black mulch treatment. Moreover, two whitefly resistant Citrullus colocynthis (L.) Schrad genotypes, which are wild relatives of cultivated watermelon, reduced whitefly populations as compared with standard watermelon. There was generally no interaction between the mulch and genotype variables. No effect of mulch color was observed on sticky card capture of Delphastus catalinae (Horn), a whitefly predator, or on capture of an Eretmocerus sp. whitefly parasitoid in caged trials, which suggests no adverse effect on these natural enemies when using reflective mulch. Overall whitefly populations were relatively low during four seasons of field trials (2006-2009). Results from this study suggest that a combination of using reflective mulch and host plant resistance can additively suppress whitefly infestations, which have particular importance in the fast-growing organic vegetable production industry.

We qualitatively examine the influence of working-class whiteness on workers' 'structure of feeling' or emotive responses regarding the move to post-production activities. Building on critical white studies, we argue that white fishermen have not been able to secure black support for the fishermen's resistance to restructuring because of differing structures of feeling these groups have towards economic diversification. In turn, alternative structures of feelings for whites and blacks derive from racialized, local landscapes and contemporary occupational segregation in fisheries. Adapted from the source document.

AN - 748948425; 20498337 AB - The molecular mechanisms responsible for selenium (Se) tolerance and hyperaccumulation were studied in the Se hyperaccumulator Stanleya pinnata (Brassicaceae) by comparing it with the related secondary Se accumulator Stanleya albescens using a combination of physiological, structural, genomic, and biochemical approaches. S. pinnata accumulated 3.6-fold more Se and was tolerant to 20 microm selenate, while S. albescens suffered reduced growth, chlorosis and necrosis, impaired photosynthesis, and high levels of reactive oxygen species. Levels of ascorbic acid, glutathione, total sulfur, and nonprotein thiols were higher in S. pinnata, suggesting that Se tolerance may in part be due to increased antioxidants and up-regulated sulfur assimilation. S. pinnata had higher selenocysteine methyltransferase protein levels and, judged from liquid chromatography-mass spectrometry, mainly accumulated the free amino acid methylselenocysteine, while S. albescens accumulated mainly the free amino acid selenocystathionine. S. albescens leaf x-ray absorption near-edge structure scans mainly detected a carbon-Se-carbon compound (presumably selenocystathionine) in addition to some selenocysteine and selenate. Thus, S. albescens may accumulate more toxic forms of Se in its leaves than S. pinnata. The species also showed different leaf Se sequestration patterns: while S. albescens showed a diffuse pattern, S. pinnata sequestered Se in localized epidermal cell clusters along leaf margins and tips, concentrated inside of epidermal cells. Transcript analyses of S. pinnata showed a constitutively higher expression of genes involved in sulfur assimilation, antioxidant activities, defense, and response to (methyl)jasmonic acid, salicylic acid, or ethylene. The levels of some of these hormones were constitutively elevated in S. pinnata compared with S. albescens, and leaf Se accumulation was slightly enhanced in both species when these hormones were supplied. Thus, defense-related phytohormones may play an important signaling role in the Se hyperaccumulation of S. pinnata, perhaps by constitutively up-regulating sulfur/Se assimilation followed by methylation of selenocysteine and the targeted sequestration of methylselenocysteine.

In this study, we assessed the influence of soil disturbance and cover cropping on the germinable seedbank of Chenopodium album, Abutilon theophrasti and Setaria spp. across a range of initial weed seedbank densities. Cover crop system treatments ranged from greater reliance on tillage at one extreme, to a greater reliance on cover cropping to accomplish weed suppression at the other. In general, seedbank losses to germination were highest when soil disturbance was associated with cover cropping. Of the five cover crop systems (1 year duration), the summer fallow and the yellow mustard-buckwheat-winter rape mixture consistently decreased the weed seedbank. The magnitude of decline in these high disturbance systems reached complete depletion of the Setaria spp. germinable seedbank and an 85% and 80% reduction for C. album and A. theophrasti respectively. Both systems included tilling the soil three to four times throughout the growing season. In contrast, treatments which involved less soil disturbance had weed escapes that set seed in one or more site years. Cover crop systems that stimulated weed seed germination and where weeds were either suppressed by the cover crop or where subsequent tillage provided control, resulted in the greatest weed seedbank declines.

Partial alkaline or enzymatic hydrolyses of blood meal, feather meal, and meat and bone meal were performed to liberate proteins and peptides from their water-insoluble forms. Some of these extracts promoted flocculation. However, if hydrolysis was extensive, low molecular weight peptides were mainly produced, and these extracts did not promote flocculation. Beef skin gelatins and hydrolyzed fish collagen were found to promote flocculation when pH 5.5 buffer was added. Commercial preparations of peptone enzymatic digest and a mixture of keratin and hydrolyzed keratin did not promote flocculation.

The main objective of this study was to determine a minimal number of spectral fluorescence bands suitable for detecting microbial biofilms on surfaces commonly used to process and handle food. Spots of biofilm growth were produced on sample surfaces by spot-inoculations of pathogenic Escherichia coli O157:H7 and Salmonella followed by room temperature storage for 3 days. Subsequently, hyperspectral fluorescence images were acquired from 421 to 700 nm using ultraviolet-A excitation. Both E. coli O157:H7 and Salmonella biofilms emitted fluorescence predominantly in the blue to green wavelengths with emission maxima at approximately 480 nm. A single-band image at 559 nm was able to detect the biofilm spots on stainless steel. On HDPE and granite, algorithms using different two-band ratios provided better separation of the biofilm spots from background areas than any single-band images did. The biofilm spots on stainless steel, HDPE, and granite could be detected with overall detection rate of 95%. On Formica, too many false positives were present to accurately determine an effective biofilm detection rate. This may have been due to the lower cell population density that was observed for the biofilm spots grown on Formica (approximately 4.3-6.4 log cfu cm super(-2)) as compared to the other surfaces. These findings can be incorporated into developing portable hand-held imaging devices for sanitation inspection of food processing surfaces.

AN - 733995029; 20542314 AB - Contamination of soil interstitial waters by labile heavy metals such as Cu(II), Cd(II), and Ni(II) is of worldwide concern. Carbonaceous materials such as char and activated carbon have received considerable attention in recent years as soil amendment for both sequestering heavy metal contaminants and releasing essential nutrients like sulfur. Information is currently lacking in how aging impacts the integrity of biochars as soil amendment for both agricultural and environmental remediation purposes. Major contributors to biochar aging in soils are: sorption of environmental constituents, especially natural organic matter (NOM), and oxidation. To investigate the impact of NOM and organic fractions of chars, we employed broiler litter-derived chars and steam-activated carbons that underwent varying degrees of carbonization, in the presence and absence of NOM having known carboxyl contents. For aging by oxidation, we employed phosphoric acid activated carbons that underwent varying degrees of oxidation during activation. The results suggest that the organic fractions of biochars, and NOM having high carboxyl contents can mobilize Cu(II) retained by alkaline soil. Base treatment of broiler litter-derived char formed at low pyrolysis temperature (350 degrees C) improved the immobilization of all heavy metals investigated, and the extent of immobilization was similar to, or slightly greater than pecan shell-derived phosphoric acid activated carbons. Portions of total sulfur were released in soluble form in soil amended with broiler litter-derived carbons, but not pecan shell-derived phosphoric acid activated carbons. (c) 2010 Elsevier Ltd.

AN - 733982918; 20392901 AB - Cell-to-cell movement of potexviruses requires coordinated action of the coat protein and triple gene block (TGB) proteins. The structural properties of Alternanthera mosaic virus (AltMV) TGB3 were examined by methods differentiating between signal peptides and transmembrane domains, and its subcellular localization was studied by Agrobacterium-mediated transient expression and confocal microscopy. Unlike potato virus X (PVX) TGB3, AltMV TGB3 was not associated with the endoplasmic reticulum, and accumulated preferentially in mesophyll cells. Deletion and site-specific mutagenesis revealed an internal signal VL(17,18) of TGB3 essential for chloroplast localization, and either deletion of the TGB3 start codon or alteration of the chloroplast-localization signal limited cell-to-cell movement to the epidermis, yielding a virus that was unable to move into the mesophyll layer. Overexpression of AltMV TGB3 from either AltMV or PVX infectious clones resulted in veinal necrosis and vesiculation at the chloroplast membrane, a cytopathology not observed in wild-type infections. The distinctive mesophyll and chloroplast localization of AltMV TGB3 highlights the critical role played by mesophyll targeting in virus long-distance movement within plants.

Forest Road Erosion Control Using Multiobjective Optimization. Journal of the American Water Resources Association (JAWRA) 46(4): 712-723. DOI: 10.1111/j.1752-1688.2010.00443.x Abstract: Forest roads are associated with accelerated erosion and can be a major source of sediment delivery to streams, which can degrade aquatic habitat. Controlling road-related erosion therefore remains an important issue for forest stewardship. Managers are faced with the task to develop efficient road management strategies to achieve conflicting environmental and economic goals. This manuscript uses mathematical programming techniques to identify the efficient frontier between sediment reduction and treatment costs. Information on the nature of the tradeoffs between conflicting objectives can give the decision maker more insight into the problem, and help in reaching a suitable compromise solution. This approach avoids difficulties associated with a priori establishment of targets for sediment reduction, preferences between competing objectives, and mechanisms to scale noncommensurate objectives. Computational results demonstrate the utility of this multiobjective optimization approach, which should facilitate tradeoff analysis and ideally promote efficient erosion control on forest roads.

However, irrigation on undeveloped sites is costly. Vertical irrigation tubes that direct applied moisture to subsurface zones where evaporation is reduced, and hydrogels that prevent applied moisture from infiltrating beyond plant root zones can maximize the portion of applied water available for plant uptake. The survival and growth of Bouteloua eriopoda (Torr.) Torr. transplants irrigated with either starch- or acrylic-based hydrogels contained in one of three embedded watering tube styles were evaluated in a greenhouse trial. A field trial evaluated differences in transplant survival and cover between treatments consisting of embedded watering tubes with or without acrylic hydrogels. Greenhouse transplants from all treatments grew 146 days on less than 1aaL of water. Plants irrigated with starch hydrogels consumed the most water and exhibited the most growth. Variations in tube styles had minor effects on plant growth and water loss from tubes. In the field, heavy growing season precipitation was observed, and transplant survival was high for both treatments. No significant differences in cover were detected. Greenhouse data demonstrate potential for hydrogel filled, embedded tubes to provide adequate moisture for establishment and growth of deep-rooted black grama transplants. Field data indicate deep-rooted black grama transplants establish successfully when adequate moisture is available.

We assessed transformations between P pools across four sites spanning the shortgrass steppe, mixed grass prairie, and tallgrass prairie along a 400-mm precipitation gradient across the central Great Plains. Pedon total elemental and constituent mass balance analyses reflected a pattern of increased chemical weathering from the more arid shortgrass steppe to the more mesic tallgrass prairie. Soil surface A horizon P accumulation was likely related to increased biocycling and biological mining. Soluble P, a small fraction of total P in surface A horizons, was greatest at the mixed grass sites. The distribution of secondary soil P fractions across the gradient suggested decreasing Ca-bound P and increasing amounts of occluded P with increasing precipitation. Surface A horizons contained evidence of Ca-bound P in the absence of CaCO3, while in subsurface horizons the Ca-bound P was associated with increasing CaCO3 content. Calcium-bound P, which dominates in water-limited systems, forms under different sets of soil chemical conditions in different climatic regimes, demonstrating the importance of carbonate regulation of P in semi-arid ecosystems.

13247833 AB - Fire injury was characterized and survival monitored for 5677 trees >25cm DBH from five wildfires in California that occurred between 2000 and 2004. Logistic regression models for predicting the probability of mortality 5-years after fire were developed for incense cedar (Calocedrus decurrens (Torr.) Florin), white fir (Abies concolor (Gord. & Glend.) Lindl. ex Hildebr.), sugar pine (Pinus lambertiana Douglas), Jeffrey pine (P. jeffreyi Balf.), and ponderosa pine (P. ponderosa C. Lawson). Differences in crown injury variables were also compared for Jeffrey and ponderosa pine. Most mortality (70-88% depending on species) occurred within 2 years post-wildfire and had stabilized by year 3. Crown length and crown volume injury variables predicted tree mortality equally well; however, the variables were not interchangeable. Crown injury and cambium kill rating was significant in predicting mortality in all models. DBH was only a significant predictor of mortality for white fir and the combined ponderosa and Jeffrey pine models developed from the McNally Fire; these models all predicted increasing mortality with increasing tree size. Red turpentine beetle (Dendroctonus valens) was a significant predictor variable for sugar pine, ponderosa pine, and Jeffrey pine; ambrosia beetle (Trypodendron and Gnathotrichus spp.) was a significant predictor variable for white fir. The mortality models and post-fire tree survival characteristics provide improved prediction of 5-year post-wildfire tree mortality for several California conifers. The models confirm the overall importance of crown injury in predicting post-fire mortality compared to other injury variables for all species. Additional variables such as cambium kill, bark beetles, and tree size improved model accuracies, but likely not enough to justify the added expense of data collection.
