AB Phaedranassa schizantha is a species endemic to Ecuador from which eight polymorphic microsatellite loci were isolated from an enriched genomic library. A total of 31 alleles with an average of four alleles per locus were detected across 29 individuals from a single natural population of P. schizantha. Observed heterozygosity ranged from 0.05 to 0.68. Most of the eight loci were successfully amplified in six Phaedranassa species. Five of those species are either "Vulnerable" or "Endangered" under IUCN criteria. These loci will be used to investigate patterns of inter- and intraspecific variation of Phaedranassa species, which will contribute data relevant to their conservation status.

AB The Indiana bat (Myotis sodalis) is a highly endangered vespertilionid bat whose distribution is associated with limestone caves in the eastern United States. We present nine new polymorphic nuclear microsatellite markers for Myotis sodalis developed using an enriched library method. A total of 62 M. sodalis from two populations were used to estimate genetic diversity parameters. In M. sodalis, the number of alleles observed for each locus ranged from 17 to 48 alleles and expected heterozygosity ranged from 0.894 to 0.973. The 9 microsatellite markers were also tested on M. gricescens, M. leibii, M. lucifugus, and M. septentrionalis. These polymorphic microsatellite markers provide a valuable tool for investigating the population genetics of these species and will provide important genetic data useful for the conservation and recovery of the endangered Indiana bat.

AB Creation of national parks often imposes immediate livelihood costs on local people, and tensions between park managers and local people are common. Park managers have tried different approaches to managing relationships with local people, but nearly all include efforts to promote environmental values and behaviors. These efforts have had uneven results, and there is a need to improve our understanding of how environmental values develop, change, and influence behavior. We investigated this question in a study of communities in and adjacent to national parks in Costa Rica and Honduras, using a mental and cultural model approach. We found local people to be fluent in global environmental values, but some common values had limited impact on behavior due to conflicts with livelihood needs. However, new environmental values that integrated conservation and livelihood needs had developed that had a more direct relationship to behavior. We propose a general model of how local environmental values develop in the context of global environmentalism that can be used to guide outreach programs with park neighbors.

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

AB Several rhizobacteria play a vital role in plant protection, plant growth promotion and the improvement of soil health. In this study, we have isolated a strain of Lysobacter antibioticus HS124 from rhizosphere and demonstrate its antifungal activity against various pathogens including Phytophthora capsici, a destructive pathogen of pepper plants. L. antibioticus HS124 produced lytic enzymes such as chitinase, beta-1,3-glucanase, lipase, protease, and an antibiotic compound. This antibiotic compound was purified by diaion HP-20, silica gel, sephadex LH-20 column chromatography and high performance liquid chromatography. The purified compound was identified as 4-hydroxyphenylacetic acid by gas chromatography-electron ionization (GC-EI) and gas chromatography-chemical ionization (GC-CI) mass spectrometry. This antibiotic exhibited destructive activity toward P. capsici hyphae. In vivo experiments utilizing green house grown pepper plants demonstrated the protective effect of L. antibioticus HS124 against P. capsici. The growth of pepper plants treated with L. antibioticus culture was enhanced, resulting in greater protection from fungal disease. Optimum growth and protection was found when cultures were grown in presence of Fe(III). Additionally, the activities of pathogenesis-related proteins such as chitinase and beta-1,3-glucanase decreased in roots, but increased in leaves with time after treatment compared to controls. Our results demonstrate L. antibioticus HS124 as a promising candidate for biocontrol of P. capsici in pepper plants.

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

AB Disease spread has traditionally been described as a traveling wave of constant velocity. However, aerially dispersed pathogens capable of long-distance dispersal often have dispersal gradients with extended tails that could result in acceleration of the epidemic front. We evaluated empirical data with a simple model of disease spread that incorporates logistic growth in time with an inverse power function for dispersal. The scale invariance of the power law dispersal function implies its applicability at any spatial scale; indeed, the model successfully described epidemics ranging over six orders of magnitude, from experimental field plots to continental-scale epidemics of both plant and animal diseases. The distance traveled by epidemic fronts approximately doubled per unit time, velocity increased linearly with distance (slope similar to A1/2), and the exponent of the inverse power law was approximately 2. We found that it also may be possible to scale epidemics to account for initial outbreak focus size and the frequency of susceptible hosts. These relationships improve understanding of the geographic spread of emerging diseases, and facilitate the development of methods for predicting and preventing epidemics of plants, animals, and humans caused by pathogens that are capable of long-distance dispersal.

AB Water resources are under pressure globally due to growing population, human migration into and regions, and diverse competing needs. In recent decades, progress in the study of information (informatics) and its manipulation via computer-based tools has stimulated development of data systems in many natural resources disciplines. Such informatics systems provide data storage, access, visualization, perhaps with analysis/modelling tools, and download capacity. Application of database technology can overcome problems of fragmentation, inadequate documentation, and cumbersome manipulation of complex data. Data management was a critical requirement for USDA's Conservation Effects Assessment project (CEAP) which was established to quantify environmental effects of agricultural conservation practices. Although USDA and the Agricultural Research Service (ARS) have conducted watershed research since early 20th century, the data have been managed and disseminated independently from each research location, reducing accessibility and utility of these data for policy-relevant, multi-site analyses. To address these concerns, STEWARDS (Sustaining the Earth's Watersheds-Agricultural Research Data System) was developed to compile, document, and provide access to data from loosely Coupled research watersheds. The STEWARDS case study is used to illustrate the role of data management in enhancing ecohydrological research and evolving information technologies available to improve data management from complex ecohydrologic studies.

AB Large-scale habitat preferences of riverine taxa are not always revealed by examining community data. Here, we show how lipid and growth can be used to evaluate hydrologic habitat preferences of fishes resilient to river fragmentation (i.e. species that can tolerate river fragmentation by dams, but not collapse). Lipid content was examined for seven fishes in a major southeastern USA reservoir and its largest lotic tributary over the 5 years. Controlling for effects of sex, size and year of collection, largemouth bass, spotted bass and black crappie had significantly higher lipid in lentic habitat. Conversely, channel catfish and freshwater drum had significantly higher lipid in lotic habitat. There were no significant differences in lipid of bluegill and blacktail shiner between hydrologic habitat types. Fish growth produced concordant results as largemouth bass and spotted bass had significantly faster growth in lentic habitat, whereas channel catfish and freshwater drum had significantly faster growth in lotic habitat. We were also able to document a synchronous spike in lipids of these species in both habitat types during a major drought. We surmise that the spike was driven by enhanced primary production, predator-prey concentration and possibly also reduced reproduction during intense drought. Two conclusions are drawn from this study as a whole. First, long-term lipid and growth observations hold promise for evaluating ecological effects of droughts over long time spans. Second, population characteristics are excellent indicators of habitat preferences and could be used more broadly to elucidate how organisms react to river ecosystem fragmentation and restoration initiatives.

AB The identity and impact of trophic linkages within subterranean arthropod communities are challenging to establish, a fact that hinders the development of conservation biological control programs of subterranean herbivores. Diabrotica virgifera (the western corn rootworm) is a severe agricultural pest that lives subterraneously during its pre-imaginal stages and succumbs to high levels of pre-imaginal mortality from unknown agents. The guts of 1500 field-collected arthropod predators were analyzed for D. virgifera-specific DNA sequences using quantitative polymerase chain reaction (qPCR). These gut analyses were used to generate relative and taxon-specific prey consumption indices for the major predator taxa and to determine relative consumption levels during D. virgifera egg and larval stages by predator feeding guilds. Laboratory feeding assays were used to determine the meal size consumed during 5 min and digestion rates of D. virgifera DNA of four predators abundant in D. virgifera-infested cornfields. More than 17 taxa consumed D. virgifera in the field. Harvestmen and small rove beetles were the most abundant predators captured, and the most frequent predators within the community to consume D. virgifera. The largest proportions of individual species' populations testing positive for D. virgifera DNA were found in ground beetles (Scarites quadriceps and Poecilus chalcites) and spiders, wolf spiders, and predaceous mites. Because of the longer duration of the egg stage, significantly more predators consumed D. virgifera eggs than larvae, but a similar proportion of the predator community fed on eggs and larvae. Predators with sucking mouthparts had a higher consumption index than chewing predators. Laboratory assays confirmed that sucking predators consume more D. virgifera DNA during 5 min than the chewing predators, and all four predators digested this DNA at a similar rate. This research substantiates that a diverse community of soil-dwelling and subterranean predators contribute to the high level of mortality incurred by D. virgifera in cornfields (similar to 99% pre-adult mortality). Moreover, qPCR is a useful tool for describing trophic relationships within subterranean food webs, a crucial step in determining the relative contributions of a diverse predator community to the population dynamics of an herbivorous arthropod.

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

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

AB 1. Numerous studies have reported the effects of learning or experience on parasitoid host preference and location. However, the integration of pre-imaginal and adult experiences on the subsequent host preference and adult/offspring performance has been rarely tested in host-parasite interactions.
2. We present direct evidence that theses two kinds of experiences affect host preference and related fitness in the polyphagous parasitoid, Scleroderma guani. Two colonies of parasitoids were reared on Monochamus alternatus and Saperda populnea (Cerambycidae: Lamiinae). Individuals from the two colonies were given host-switching experience for one generation (pre-imaginal experience) while other individuals were given prior ovipositing experience on the two species, respectively (adult experience).
3. Scleroderma guani females demonstrated that their experiences determined adult behavioural responses and their subsequent performance to hosts. Females maximised both adult fitness (fecundity and longevity) and offspring fitness (survival and sex ratio) when they encountered hosts similar to their maternal hosts. Behavioural plasticity in host choice was affected by adult experience, resulting in improved adult feeding and ovipositing behaviour and further modifying adult fecundity and the offspring sex ratio. There was a positive correlation between oviposition preference and adult fecundity.
4. The results indicated that S. guani exhibited positive preference-performance correlations. This is most likely due to an adaptation to maternal hosts over multiple generations. However, foraging potential of adults to available cues from hosts may be driven quickly by an experience-induced learning process rather than by natural selection processes shaped over many generations.

AB 1. The level of an organism's investment in defences against natural enemies depends on the fitness costs of resisting parasitism and on the costs of maintaining defences in the absence of infection. Heritable variation in resistance suggests that costs exist, but very little is known about the nature or magnitude of these costs in natural populations of animals.
2. A powerful technique for identifying trade-offs between fitness components is the study of correlated responses to artificial selection. We selected for increased resistance in the Indian meal moth, Plodia interpunctella, following parasitism by the koinobiont parasitoid, Venturia canescens, and measured the cost of resistance to parasitism and the cost of maintaining resistance in the absence of immune challenge during the next generation.
3. Parasitism decreased larval host size, growth, and developmental time and was significantly negatively correlated with the size of surviving host adults. Larvae of the next generation also had a reduced developmental period, whilst the duration of the invulnerable pupal instar was increased. There was no effect on host adult size and related fecundity in the F(1) generation.

AB The role of climate variability in the ecology of freshwater fishes is of increasing interest. However, there are relatively few tools available for examining how freshwater fish populations respond to climate variations. Here, I apply tree-ring techniques to incremental growth patterns in largemouth bass (Micropterus salmoides Lacepede) otoliths to explore relationships between annual bass growth and various climate metrics in the southeastern USA. Among six rivers and seven reservoirs in Georgia, Alabama, and Mississippi, strong correlations between annual bass growth indices and climate were detected (73 of 96 possible correlations were significant at alpha < 0.05). All but two ecosystems exhibited the following pattern: annual bass growth was significantly negatively correlated with annual precipitation metrics, and significantly positively correlated with annual temperature metrics. Based on multiple regressions, climate, on average, accounted for similar to 50% of variability (R-2) in bass growth, although these values ranged from 28% to 65% depending on the ecosystem. Furthermore, every population showed significant correlations with at least one of the following global climate factors: El Nino-Southern Oscillation (ENSO), North Atlantic Oscillation (NAO), and the Arctic Oscillation (AO). Largemouth bass growth in the southeast is apparently influenced by climate in major ways. Fish ecologists and managers in the region should be aware of the strong links between annual climate conditions and annual fish growth.

AB This study quantifies the short-term effects of low-, moderate-, and high-severity fire on carbon pools and fluxes in the Eastern Cascades of Oregon. We surveyed 64 forest stands across four fires that burned 41,000 ha (35%) of the Metolius Watershed in 2002 and 2003, stratifying the landscape by burn severity (overstory tree mortality), forest type (ponderosa pine [PP] and mixed-conifer [MC]), and prefire biomass. Stand-scale C combustion ranged from 13 to 35% of prefire aboveground C pools (area - weighted mean = 22%). Across the sampled landscape, total estimated pyrogenic C emissions were equivalent to 2.5% of statewide anthropogenic CO(2) emissions from fossil fuel combustion and industrial processes for the same 2-year period. From low- to moderate- to high-severity ponderosa pine stands, average tree basal area mortality was 14, 49, and 100%, with parallel patterns in mixed-conifer stands (29, 58, 96%). Despite this decline in live aboveground C, total net primary productivity (NPP) was only 40% lower in high- versus low-severity stands, suggesting strong compensatory effects of non-tree vegetation on C uptake. Dead wood respiratory losses were small relative to total NPP (range: 10-35%), reflecting decomposition lags in this seasonally arid system. Although soil C, soil respiration, and fine root NPP were conserved across severity classes, net ecosystem production (NEP) declined with increasing severity, driven by trends in aboveground NPP. The high variability of C responses across this study underscores the need to account for landscape patterns of burn severity, particularly in regions such as the Pacific Northwest, where non-stand-replacement fire represents a large proportion of annual burned area.

AB The control of glucose metabolism is a complex process, and dysregulation at any level can cause impaired glucose tolerance and insulin resistance. These two defects are well-known characteristics associated with obesity and onset of type 2 diabetes. Here we introduce the N-terminal dipeptidase, DPP2, as a novel regulator of the glucose metabolism. We generated mice with a neurogenin 3 (NGN3)-specific DPP2 knockdown (kd) to explore a possible role of DPP2 in maintaining metabolic homeostasis. These mice spontaneously developed hyperinsulinemia, glucose intolerance, and insulin resistance by 4 months of age. In addition, we observed an increase in food intake in DPP2 kd mice, which was associated with a significant increase in adipose tissue mass and enhanced liver steatosis but no difference in body weight. In accordance with these findings, the mutant mice had a higher rate of respiratory exchange than the control littermates. This phenotype was exacerbated with age and when challenged with a high-fat diet. We report, for the first time, that DPP2 enzyme activity is essential for preventing hyperinsulinemia and maintaining glucose homeostasis. Interestingly, the phenotype of NGN3-DPP2 kd mice is opposite that of DPP4 knockout mice with regard to glucose metabolism, namely the former have normal glucagon-like peptide 1 levels but present with glucose intolerance, whereas the latter have increased glucagon-like peptide 1, which is accompanied by augmented glucose tolerance.

ID AIR-POLLUTION; LUNG-CANCER
AB The hypothesis of this study is that there is a statistical relationship between the lung cancer mortality rate and the intensity of fuel consumption (measured in gallons/square mile) at a particular location. We estimate cross-section regressions of the mortality rate due to lung cancer against the intensity of fuel consumption using local data for the entire US, before the US Clean Air Act (CAA) in 1974 and after the most recent policy revisions in 2004. The cancer rate improvement estimate suggests that up to 10 lung cancer deaths per 100,000 residents are avoided in the largest urban areas with highest fuel consumption per square mile. In New York City, for instance, the mortality reduction may be worth about $5.7 billion annually. Across the US, the estimated value of statistical life (VSL) benefit is $27.2 billion annually. There are likely three inseparable reasons that contributed importantly to this welfare improvement. First, the CAA regulations mandated reduction in specific carcinogenic chemicals or smog components. Second, technologies such as the catalytic converter (CC) and low-particulate diesel engine were adopted. Third, biofuels have had important roles, making the adoption of clean air technology possible and substituting for high emission fuels. (C) 2009 Elsevier Ltd. All rights reserved.

TI An outlook for sustainable forest bioenergy production in the Lake
States
SO ENERGY POLICY
LA English
DT Article
DE Bioenergy; Bioeconomy; Lake States
AB The Lake States region of Minnesota, Wisconsin and Michigan offers significant potential for bioenergy production. We examine the sustainability of regional forest biomass use in the context of existing thermal heating, electricity, and biofuels production, projected resource needs over the next decade including existing forest product market demand, and impacts on price and feasibility. Assuming $36 per dry tonne at roadside, 4.1 million dry tonnes of forest biomass could be available region-wide. However, less is likely available due to localized environmental and forest cover type constraints, and landowner willingness to harvest timber. Total projected demand of 5.7 million dry tonnes, based on current and announced industry capacity, exceeds estimates of biomass availability, which suggests that anticipated growth in the forest-based bioeconomy may be constrained. Attaining projected demand will likely require a combination of higher cost feedstocks, integration of energy and non-energy uses, and careful management to meet environmental constraints. State distinctions in biomass harvest guidelines and the propensity for third-party forest certification will be critical in providing environmental safeguards. The cumulative effect of policy initiatives on biomass competition are discussed in the context of an emerging Lake States bioeconomy. (C) 2009 Elsevier Ltd. All rights reserved.

AB We examined phenyl propionate as an attractant for trapping navel orangeworm, Amyelois transitella (Walker) (Lepidoptera: Pyralidae) adults, with the objective of developing a method of trapping both sexes more effectively than with almond meal. Two initial experiments maximized the total number of adults captured using phenyl propionate released from glass vials with cotton wicks. A third experiment compared the numbers of males and females captured using these glass dispensers in either bucket or sticky traps. The glass vial dispensers captured more adults than 0.1% phenyl propionate in water (as both attractant and killing agent), and far more adults were captured with glass vial phenyl propionate dispensers than with almond meal. On rare occasion, the glass vial dispensers captured as many adults as traps baited with virgin females, but usually phenyl propionate in glass vials captured fewer adults than virgin-baited traps. Glass vial phenyl propionate dispensers were equally effective in sticky traps or bucket traps. The majority of females captured were mated, and the proportion of males captured increased over time within flights (generations). We conclude that phenyl propionate released from glass vials captured A. transitella adults more effectively than currently available options, and will be useful in research projects where capturing intact adults and comparing mating status are important. Developing a cost-effective phenyl propionate-based alternative to the egg traps currently used for commercial monitoring will be more difficult.

AB The movement of humans and goods has facilitated the arrival of non-native insects, some of which successfully establish and cause negative consequences to the composition, services, and functioning of ecosystems. The gypsy moth, Lymantria dispar (L.) (Lepidoptera: Lymantriidae), is currently invading North American forests at variable rates, spreading by local and long-distance movement in a process known as stratified dispersal. Newly arriving colonizers often occur considerably ahead of the population front, and a key question is the degree to which they successfully establish. Prior research has highlighted mate-finding failures in sparse populations as a cause of an Allee effect (positive density dependence). We explored this mechanism by measuring the relationship between female mating success and background male moth densities along the gypsy moth western front in Northern Wisconsin (USA) over 2 years. The mating results were then compared with analogous previous studies in southern Wisconsin, and the southern front in West Virginia and Virginia (USA). Mate-finding failures in low-density populations were consistently observed to be density-dependent across all years and locations. Mate-finding failures in low-density populations have important ramifications to invasive species management, particularly in predicting species invasiveness, preventing successful establishment by small founder populations, and concentrating eradication efforts where they are most likely to succeed.

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

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

AB Emerald ash borer, Agrilus planipennis Fairmaire (Coleoptera: Buprestidae), has killed millions of ash (Fraxinus sp.) trees in North America since its discovery in Michigan in 2002. Efficient methods to detect low-density A. planipennis populations remain a critical priority for regulatory and resource management agencies. We compared the density of adult A. planipennis captured on sticky bands and larval density among ash trees that were girdled for 1 or 2 yr, wounded, exposed to the stress-elicitor methyl jasmonate, baited with Manuka oil lures, or left untreated. Studies were conducted at four sites in 2006 and 2007, where A. planipennis densities on untreated trees ranged from very low to moderate. In 2006, 1-yr girdled trees captured significantly more adult A. planipennis and had higher larval densities than untreated control trees or trees treated with methyl jasmonate or Manuka oil. Open-grown trees captured significantly more A. planipennis beetles than partially or fully shaded trees. In 2007, A. planipennis population levels and captures of adult A. planipennis were substantially higher than in 2006. The density of adults captured on sticky bands did not differ significantly among canopy exposure classes or treatments in 2007. Larval density was significantly higher in untreated, wounded, and 1-yr girdled trees (girdled in 2007) than in 2-yr girdled trees (girdled in 2006), where most phloem was consumed by A. planipennis larvae the previous year. A total of 36 trees (32 in 2006, 4 in 2007) caught no beetles, but 16 of those trees (13 in 2006, 3 in 2007) had A. planipennis larvae. In 2006, there was a positive linear relationship between the density of adults captured on sticky bands and larval density in trees. Our results show that freshly girdled and open grown trees were most attractive to A. planipannis, especially at low-density sites. If girdled trees are used for A. planipennis detection or survey, debarking trees to locate larval galleries is crucial.

AB The male-produced pheromone of Anoplophora glabripennis (Motschulsky) (Coleoptera: Cerambycidae), which is an equal blend of 4-(n-heptyloxy)butan-1-ol mid 4-(n-heptyloxy)butanal, was used in laboratory bioassays and in the greenhouse to determine its potential for attracting A. glabripennis adults. In modified "walking wind tunnels," virgin females were most attracted to the alcohol component, and virgin males were repelled by the pheromone blend at the lowest and highest amounts offered. Y-tube olfactometer bioassays also showed that females were significantly more attracted to the pheromone and its components than males were. However, males were more attracted to plant volatiles than females. Of 12 plant volatiles tested, delta-3-carene and (E)-caryophyliene were highly attractive to males, whereas (Z) -3-hexenyl acetate was repellent to males. Combining the male pheromone blend with (-)-linalool alone or with (Z)-3-hexen-1-ol attracted significantly more males than did the pheromone alone. We tested four trap designs in our quarantine greenhouse with eight different lures. The Intercept Panel traps and the hand-made screen sleeve traps caught more beetles than the Plum Curculio traps and Lindgren funnel traps. Intercept traps worked best when baited with male blend and (Z)-3-hexen-1-ol, whereas screen sleeve traps were most attractive when baited with (-) -linalool. Our findings provide evidence of the attractiveness of the A. glabripennis male-produced pheromone and suggest that it has a role in mate-finding. It is also a first step toward the development of an efficient trap design and lure combination to monitor A. glabripennis infestations in the field.

AB The emerald ash borer, Agrilus planipennis Fairmaire (Coleoptera: Buprestidae), is an exotic woodborer first detected in 2002 in Michigan and Ontario and is threatening the ash resource in North America. We examined the effects of light exposure and girdling on green ash (Fraxinus pennsylvanica Marsh) volatile production, and effects of light exposure, girdling, and leaf age on emerald ash borer adult feeding preferences and phototaxis. Green ash seedlings grown under higher light exposure had lower amounts of three individual volatile compounds, (Z)-3-hexenol, (E)-beta-ocimene, and (Z,E)-alpha-farnesene, as well as the total amount of six detected volatile compounds. Girdling did not affect the levels of these volatiles. Emerald ash borer females preferred mature leaves, leaves from girdled trees, and leaves grown in the sun over young leaves, leaves from nongirdled trees, and leaves grown in the shade, respectively. These emerald ash borer preferences were most likely because of physical, nutritional, or biochemical changes in leaves in response to the different treatments. Emerald ash borer females and males showed positive phototaxis in laboratory arenas, a response consistent with emerald ash borer preference for host trees growing in sunlight.

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

AB Past and present climate has shaped the valued ecosystems currently protected in parks and reserves, but future climate change will redefine these conditions. Continued conservation as climate changes will require thinking differently about resource management than we have in the past; we present some logical steps and tools for doing so. Three critical tenets underpin future management plans and activities: (1) climate patterns of the past will not be the climate patterns of the future; (2) climate defines the environment and influences future trajectories of the distributions of species and their habitats; (3) specific management actions may help increase the resilience of some natural resources, but fundamental changes in species and their environment may be inevitable. Science-based management will be necessary because past experience may not serve as a guide for novel future conditions. Identifying resources and processes at risk, defining thresholds and reference conditions, and establishing monitoring and assessment programs are among the types of scientific practices needed to support a broadened portfolio of management activities. In addition to the control and hedging management strategies commonly in use today, we recommend adaptive management wherever possible. Adaptive management increases our ability to address the multiple scales at which species and processes function, and increases the speed of knowledge transfer among scientists and managers. Scenario planning provides a broad forward-thinking framework from which the most appropriate management tools can be chosen. The scope of climate change effects will require a shared vision among regional partners. Preparing for and adapting to climate change is as much a cultural and intellectual challenge as an ecological challenge.

AB Between 1992 and 2004, air contamination with lead (Pb), cadmium (Cd), and zinc (Zn) in Warsaw, Poland, was monitored annually with moss (Sphagnum fallax) bags on a network of 230 sites covering the entire city. During the study the highest contamination was near the Warszawa Steel Mill, northwestern Warsaw. Lead concentrations in moss bags decreased in time, while those of Cd and Zn did not show clear trends. Between 1994 and 2004, Pb, Cd, and Zn were also monitored in the Crimean linden (Tilia Euchlora) foliage along the main city avenue and in a northwestern warsaw park. Lead concentrations decreased more near the avenue than in the park, indicating that the phasing-out of leaded gasoline had a major effect on reduced Pb contamination in Warsaw. At the same time, foliar concentrations of Cd and Zn in both areas decreased much less. Published by Elsevier Ltd.

AB Hotter countries are poorer on average. This paper attempts to separate the historical and contemporaneous components of this income-temperature relationship. Following ideas by Acemoglu et al. (Am Econ Rev 91(5):1369-1401, 2001), we use colonial mortality data to account for the historical role of temperature since colonial mortality was highly correlated with countries' average temperatures. The remaining income-temperature gradient, after colonial mortality is accounted for, is most likely contemporaneous. This contemporaneous effect can be used to estimate the consequences of global warming. We predict that a 1A degrees C temperature increase across all countries will cause a decrease of 3.8% in world GDP. This prediction is robust across functional forms and an alternative method for separating historical effects.

AB Knowledge of the ability of the female reproductive system to metabolize polycyclic aromatic hydrocarbons (PAHs) is critical to the diagnosis and management of female infertility and for risk assessment purposes. The PAHs are a family of widespread pollutants that are released into the environment from automobile exhausts, cigarette smoke, burning of refuse, industrial emissions, and hazardous waste sites. In exposed animals, PAHs become activated to reactive metabolites that interfere with target organ function and as a consequence cause toxicity. The extent of susceptibility to PAH exposure may depend on the ability of animals to metabolize these chemicals. The present study has been undertaken to assess whether any differences exist among mammals in the metabolism of benzo(a)pyrene (BaP), a prototypical PAH compound. Microsomes isolated from the liver and ovaries of rats, mice, goats, sheep, pigs, and cows were incubated with 5 mu M BaP Postincubation, samples were extracted with ethyl acetate and analyzed for BaP/metabolites by reverse-phase HPLC with fluorescence detection. The rate of metabolism (pmol of metabolite/min/mg protein) was found to be more in liver than in ovary in all the species studied (P < 0.05). The differences in metabolite concentrations were statistically significant (P < 0.0001) among the various species in both organs studied. Multiple species comparison also revealed that the differences were statistically significant (P < 0.001) between rodents (rat and mouse) and higher mammals (ewe, sow, and cow). Even among the higher mammals, in a majority of the cases, the differences in metabolite concentrations were significantly different (P < 0.001) both in ovary and liver. The BaP metabolites identified were 4,5-diol; 7,8-diol; 9,10-diol; 3-hydroxy BaP; and 9-hydroxy BaP. The rodent microsomes produced considerably higher proportion of BaP 4,5-diol and 9,10-diol than did cow, sow, goat, and sheep. However, microsomes from higher mammals converted a greater proportion of BaP to 3-hydroxy and 9-hydroxy BaP, the detoxification products of BaP. Overall, our results revealed a great variation among species to metabolize BaR (C) 2008 Wiley Periodicals, Inc. Environ Toxicol 24: 603-609, 2009.

AB Objective: To test the feasibility of the "Rolling Store," an innovative food-delivery intervention, along with a nutrition education program to increase the consumption of healthy foods (fruits and vegetables) to prevent weight gain in African American women.
Methods: Forty eligible African American women were enrolled in the study and randomized to intervention or control groups. A trained peer educator and a Rolling Store operator implemented the study protocol at a local community center.
Results: The program retention rate was 93%. Participants in the intervention group lost a mean weight of 2.0 kg, while participants in the control group gained a mean weight of 1.1 kg at six months. Overall participants showed a mean decrease in weight of -.4 kg (standard deviation 3.0 kg), but the intervention group lost significantly more weight and had a decreased body mass index at six months. In the intervention group, the average number of servings consumed per day of fruits/fruit juice and vegetables significantly increased at six months.
Conclusions: The Rolling Store, at least on the small scale on which it was implemented, is a feasible approach to producing weight loss and improvements in healthy eating when combined with an educational program in a small community center. (Ethn Dis. 2009;19:7-12)

ID PHENOTYPIC SELECTION
AB Red clover (Trifolium pratense L.) forage yield remains a prime breeding target for improved variety development. In a world of decreasing forage legume breeding resources, rapidly and cheaply phenotyping plants for the highly quantitative trait of forage yield is vital. Many red clover selection programs are based on space planted nurseries. The objectives of this study were to determine: (1) the accuracy of visual forage yield scores in predicting actual forage yield; (2) the nature of the relationship between visual scores and actual measurements; and (3) The repeatability of visual scores between different evaluators. Twenty-seven halfsib families were transplanted at two locations in three replicates of six plant plots. Individual plant fresh weights and visual scores, by two evaluators, for forage yield were taken. On an individual plant basis visual forage yield scores showed an exponential relationship with actual fresh weights. Individual plant visual scores were very accurate with a pseudo-R (2) of 0.79 observed for the exponential model. On an entry mean basis using a linear model, visual scores could explain 90% of the variation of actual fresh weights. Agreement among evaluators scoring the same plants was very high with coefficients of determination at 0.84 for individual plants and as high as 0.96 on an entry mean basis. This study suggests that visual scores of plants in space planted red clover breeding nurseries are basically as accurate as measuring actual yields and that plants can be consistently scored the same by different evaluators.

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

AB Objective: We explored potential associations of two single nucleotide polymorphisms (SNPs) in the adiponectin gene (ADIPOQ +45T > G, rs2241766 and +276G > T rs1501299) with circulating total and high-molecular weight (HMW) adiponectin, insulin resistance (IR), and markers of obesity in a healthy Greek female population.
Design and methods: The two SNPs were genotyped in 349 women without diabetes (mean age, 47.0 +/- 12.1 years. mean body mass index: 28.9 +/- 5.6 kg/m(2)) Total and HMW adiponectin concentrations, body composition variables. IR parameters, and plasma lipid levels were determined
Results. In single SNP analysis adjusting for several potential confounders, SNP +276G > T was associated with higher fasting insulin levels (P=0.01) and higher homeostasis model assessment index for IR (HOMA-IR: P=0.009), and SNP +45T > G was associated with lower insulin levels and HOMA-IR (P=0.05 and P=0.07 respectively). No association with total or HMW adiponectin, plasma lipid levels, and body composition variables was observed; however, haplotype analysis revealed that subjects homozygous for the most common +45T/+276G haplotype had lower total adiponectin levels than did noncarriers of this haplotype (P=0.02). The observed differences in HOMA-IR were very significant among women with a higher body fat (BF) percentage (>= the population median of 41%, all P <= 0.005), but not among leaner individuals (P for interactions 0.01-0.07), thus suggesting that ADIPOQ effects on insulin sensitivity may depend upon BF status
Conclusion: Our data suggest a significant role of ADIPOQ variants at positions +45 and +276 in the development of IR in healthy Greek women possibly through an interaction with BF.

AB Genetic resistance to Meloidogyne incognita in pepper (Capsicum annuum) has been well characterised for the N and Me3 resistance genes. However, there are no studies comparing the effects of these two genes directly or investigating the combined effects when both genes are present together. Several studies were undertaken to investigate the relationship of the N and Me3 gene systems to one another and to assess whether these two genes are allelic or truly separate genes. Two genotypes homozygous for the N gene ('Carolina Wonder' and 'Charleston Belle') and two genotypes homozygous for the Me3 gene (HDA 149 and PM 687) were compared in a replicated greenhouse test for reaction to M. incognita race 3. There were no significant differences between the resistant reactions of genotypes possessing the N or Me3 gene. Allelism tests were performed using the F2 populations of the parental genotypes HDA 149 x 'Charleston Belle' and HDA 149 x 'Carolina Wonder'. The results of these studies clearly show the N and Me3 genes to be distinct, separate dominant resistance genes conferring resistance to M. incognita race 3 and not alleles of the same gene.

SO FLORIDA ENTOMOLOGIST
LA English
DT Article
AB We report here that it is possible to rear D. areolatus on irradiated A. suspensa larvae without adversely affecting sex ratio and overall parasitoid emergence and with no adult A. suspense emergence. There was no difference in emergence of D. areolatus adults from irradiated versus non-irradiated hosts (72.4 +/- 1.9% vs. 73.0 +/- 1.9%), and no difference in sex ratio of parasitoids obtained from irradiated and non-irradiated hosts (50.0 +/- 1.6 and 47.0 +/- 1.4% female, respectively). The successful use of A. suspensa larval hosts can greatly ease the process of rearing, transporting, and releasing fruit fly parasitoids while eliminating the need to separate flies from parasitoids. Further improvements in the laboratory rearing process of D. areolatus, including irradiating late A. suspensa larvae at a lower dosage and irradiating A. suspensa as egg or early instars, are discussed.

AB Field surveys of the emerald ash borer (EAB), Agrilus planipennis Fairmaire, and associated parasitoids were conducted in Cranberry Township, PA from 11 Mar to 23 Oct 2008. Several species of parasitic Hymenoptera were collected from EAB-infested green ash trees or reared from late-instar EAB larvae, prepupae, and/or pupae. These included Balcha indica (Mani & Kaul), Eupelmus pini Taylor (Eupelmidae), Dolichomitus vitticrus Townes (Ichneumonidae), and 2 additional unidentified ichneumonids, Orthizema sp. Townes and Cubocephalus sp. Townes. Together, these parasitoids caused about 3.6% parasitism of EAB in the field. The most abundant species was B. indica accounting for 82% of all parasitoids recovered during our survey. Subsequent laboratory assays confirmed that B. indica and E. pini are solitary ectoparasitoids of EAB larvae, prepupae, and/or pupae. In addition, both B. indica and E. pini reproduce through thelytokous parthenogenesis; i.e., virgin females produce daughters. These parasitoids may be complementary to current classical biological control programs against EAB in North America, which have been focusing primarily on the introduction of exotic larval and egg parasitoids from China.

AB The infectivity and horizontal transfer of Isaria fumosorosea Wize among Diaphorina citri Kuwayama was measured using a detached leaf bioassay in which blastospores were sprayed on citrus leaf sections or yellow plastic tags (artificial attractant surface). Four leaf sections or three leaf sections and one yellow tag were placed together in a Petri dish chamber. One to four of the leaf sections or the yellow tag was sprayed with I. fumosorosea (1.2 -1.7 x 10(3) blastospores/mm(2)). After treatments dried, a single adult psyllid was released into each chamber. Mortality due to I. fumosorosea for the adult psyllid was observed 4.9 +/- 0.21- 6.1 +/- 0.37 d following exposure to the pathogen. The rate of colonization by I. fumosorosea on adults in chambers with untreated leaf sections and one treated yellow tag was as effective in inducing mortality as in chambers with one treated leaf section at 8 days post application. Under high humidity, I. fumosorosea blastospores readily produced hyphae on the surface of leaves which was useful for determining if adults were responsible for transmission of the fungus. In chambers with a single treated leaf section, adults came into contact with blastospores and moved these around to the non-treated leaves. The same phenomenon, of psyllid infection and subsequent spreading of the fungus to non-treated leaves, was observed when psyllids were placed into chambers with a treated yellow tag. The use of I. fumosorosea inoculated yellow tags has potential as a psyllid dissemination technique for managing pest populations.

AB High pressure inactivation of hepatitis A virus (HAV) within oysters bioaccumulated under simulated natural conditions to levels >10(5) PFU/oyster has been evaluated. Five minute treatments at 20 degrees C were administered at 350, 375, and 400 MegaPascals (MPa). Shucked and whole-in-shell oysters were directly compared to determine if there were any differences in inactivation levels. For whole-in-shell oysters and shucked oysters, average values obtained were 2.56 and 2.96 log(10) inactivation of HAV, respectively, after a 400-MPa treatment. Results indicate that there is no significant inactivation difference (P = 0.05) between inactivation for whole-in-shell oysters as compared to shucked oysters observed for all pressure treatments. This study indicates that commercial high pressure processing applied to whole-in-shell oysters will be capable of inactivating HAV pathogens.

AB Background. Multiple micronutrient supplements could increase hemoglobin and improve micronutrient status of pregnant women more than iron supplements alone or iron with folic acid.
Objective. To compare the effects of multiple micronutrients with those Of iron supplements alone or iron with folic acid, on hemoglobin and micronutrient status of pregnant women.
Methods. Studies were identified in which pregnant women were randomized to treatment with multiple micronutrients, or with iron with or without folic acid A pooled analysis was conducted to compare the effects of these supplements on maternal hemoglobin, anemia, and micronutrient status Effect size was calculated for individual and combined studies, based on mean change from baseline to final measure in the group receiving iron, with or without folic acid, minus the mean change in the group, divided by the pooled standard deviation Of the two groups. The effect on the relative risk of anemia or iron deficiency was calculated as the probability of anemia or iron deficiency in the group receiving multiple micronutrients divided by the probability in the group receiving iron, with or without folic acid
Results. Multiple micronutrient supplements had the same impact on hemoglobin and iron status indicators as iron with or without folic acid. There was no overall effect on serum retinol or zinc In the only study in which status of other micronutrients was analyzed, a high prevalence of multiple deficiencies persisted in the group receiving multiple micronutrients provided with daily recommended intakes of each nutrient.
Conclusions. Multiple micronutrient supplements increased hemoglobin synthesis to the same extent as supplementation with iron with or without folic acid, although often they contained lower amounts of iron The amount Of supplemental iron and other nutrients that can enable pregnant women with micronutrient deficiencies to achieve adequate status remains to be determined.

AB The levels of flavonoids in blueberries (Vaccinium corymbosum L.) were found to increase after illumination with UV-C. Phytochemicals affected included resveratrol, myricetin-3-arabinoside, quercetin-3-galactoside, quercetin-3-glucoside, kaempferol-3-glucuronide, delphinidin-3-galactoside, cyanidin-3-galactoside, delphinidin-3-arabinoside, petunidin-3-galactoside, petunidin-3-glucoside, petunidin-3-arabinoside. malvidin-3-galactoside, malvidin-3-arabinoside, and chlorogenic acid as analyzed by HPLC. Significantly higher antioxidant capacity was detected in fruit treated with 2.15, 4.30, or 6.45 kJ m(-2) compared to the control fruit. UV-C dosage of 0.43 kJ m(-2) also increased phenolics and anthocyanins, but to a lesser extent. The optimum doses of UV-C for enhancing phytochemical content in blueberries were 2.15 and 4.30 kJ m(-2). These data suggest that proper use of UV-C illumination is capable of modifying the phytochemical content of blueberries. Time course measurements of the effects of UV-C revealed that the strongest responses of fruit to UV-C treatment occurred instantly after the illumination and the effects diminished with time. Therefore, even though residual effects were evident following UV-C exposure, the best results were obtained immediately after the treatment. Published by Elsevier Ltd.

AB Many argue that food away from home (FAFH) is a contributing factor to the obesity epidemic, showing that body mass index and consumption of FAFH are positively correlated. However, correlation analyses using a simple regression approach, such as the Ordinary Least Squares (OLS), do not prove that FAFH Causes weight gain. We use a first-difference estimator to establish a causal relationship between FAFH and dietary intakes. Using dietary recall data from the 2003-2004 National Health and Nutrition Examination Survey and the 1994-1996 Continuing Survey of Food Intakes by Individuals, we find that FAFH does indeed increase caloric intake and reduce diet quality, but that the effect is smaller than if estimated using OLS. Thus, models based on associations are likely biased upward, as much as 25% by our estimates. Published by Elsevier Ltd.

AB The objective of this study was to understand the conjugative transmissibility of resistance plasmids present in 205 Salmonella enterica isolates from bovine sources. Polymerase chain reaction (PCR)-based replicon typing was used to type plasmid replicons. Conjugation experiments were preformed in triplicate at 30 degrees C and 37 degrees C on solid medium. PCR mapping of the A/C transfer gene operon was done on 17 Salmonella Newport isolates that were only positive for A/C. Eighty-six percent (n = 177) of the Salmonella isolates were multidrug resistant (MDR) with resistance to 3-12 antimicrobial agents. Of these, 82% (n = 146) were resistant to extended-spectrum cephalosporins and possessed a bla(CMY) gene. A/C was the predominant replicon detected, present in 90% (n = 160) of the MDR isolates. Twenty-three percent (n = 37) of the A/C-positive strains were positive for a second replicon. Replicons coresident with A/C included I1, N, B/O, HI1, and HI2. Only 31% (n = 54) of the MDR isolates produced transconjugants, and most of these donors carried multiple replicons. A/C cotransferred with B/O, N, and I1 at both 30 degrees C and 37 degrees C and with HI2 at 30 degrees C. Seven Salmonella Newport isolates that produced transconjugants possessed only the single A/C replicon and lacked bla(CMY). PCR mapping of the A/C transfer gene operon in ten Salmonella Newport isolates that carried bla(CMY) revealed a bla(CMY) inverted repeat element integrated between the traA and traC genes. These results suggest that A/C may have been a conjugative plasmid before the integration of bla(CMY) into the transfer gene operon. Additionally, transfer deficient A/C replicons may be mobilized in the presence of certain compatible conjugative plasmids.

AB This study examined the association of norovirus with foodborne disease outbreaks linked to food handlers and foodborne outbreaks of acute gastroenteritis associated with norovirus, in comparison to Salmonella foodborne gastroenteritis. Comparative analysis using chi(2)-tests showed no similarity between the outbreaks from norovirus and those from Salmonella. Odds ratios also showed a stronger similarity between the proportions of food handler-implicated norovirus outbreaks than from Salmonella-implicated outbreaks. An analysis of data found norovirus transmission to occur more frequently spread person-to-person, unlike Salmonella, but similar to influenza or rotavirus. Norovirus was also not shown to be associated with food consumption. The data collection tool that focuses on food handlers as a source of the virus may be better including the general human population. Such an enteric virus would be better understood through its similarity to the person-to-person transmission model resulting in pandemic spread.

AB The need for knowledge, ranging from development of new products or processes to the effects of specific actions on the environment, is greater now than at any point in the past. The greater need for research has generated stakeholder involvement in the research process. As a result, all facets of research, from planning through publication of results, are often scrutinized by stakeholders. While the basic nature of scientific inquiry has not changed, now more than ever the credibility of scientific results is based on thorough planning, peer reviews of experimental designs and analytical approaches, and assurance that data are of the highest quality. Public interest in the quality and accuracy of federal research rose to a level that resulted in the Data Quality Act of 2001. The Act required the establishment of guidelines for Federal research organizations and cooperators. We present a case study of the U. S. Forest Service's policies for research quality assurance and quality control. including developing quality assurance statements and plans, as applied to comprehensive research on the federally-listed, endangered forest shrub pondberry (Lindera melissifolia (Walt.)

AB Recently enacted federal and state policies provide incentives, including financial assistance, for local jurisdictions to manage risks associated with wildland fire. This has led to an array of local-level policies designed to encourage homeowners to create fire-safe landscapes. This qualitative study collected data from focus group interviews with homeowners in three diverse communities and used the theory of reasoned action to interpret dimensions of local-level wildland fire policies that are associated with homeowner acceptance of or compliance with defensible space guidelines or regulations. Common factors emerged in two policy evaluation categories: acceptance and compliance. WUI homeowners are more accepting of policies that are seen as fair and part of a more comprehensive risk reduction strategy. Topics that shaped acceptance of voluntary versus mandatory approaches included perceived risk severity, views about the proper roles of government, and beliefs about alternatives to regulatory approaches (e.g. private insurance, education, ignition source reduction). Program characteristics that were found to be related to beliefs about defensible space and acceptance included provision of one-on-one expert consultation, direct mail communication modes, needs-based financial assistance, and enhanced yard waste disposal options. Homeowner compliance is related to the feasibility in terms of household costs and yard waste disposal options, neighborhood norms, competing land use objectives, insurance considerations. and whether or not the policy is mandatory. These findings led to a proposed conceptual model of vegetation management policy acceptance and compliance that local governments can use to develop or amend defensible space vegetation management policies to increase policy acceptance and compliance.

ID UNITED-STATES; ECONOMICS; PROGRAM
AB The Harvest Cost-Revenue Estimator, a financial model, was used to examine the cost sensitivity of forest biomass harvesting scenarios to targeted policies designed to stimulate wildfire hazardous fuel reduction projects. The policies selected represent actual policies enacted by federal and state governments to provide incentive to biomass utilization and are aimed at addressing particular challenges in the production lifecycle of trees to final product. Policies were modeled to compare financial impacts on a per-acre project basis for three scenarios of harvest intensity in southwestern ponderosa pine stands classified as being at high risk of wildfire. This allowed for identification of key cost nodes and how particular policies might better allocate limited resources. Effects of limiting the size of trees harvested and access to biomass markets were also modeled. This analysis showed that the co-location of processing facilities that results in shorter distances traveled is the single most important strategy for reducing costs for all three scenarios modeled. Per acre subsidies and certified product premiums were the next highest ranked in providing economic incentive, followed by production tax credits and cost-share programs. Fuel surcharge waivers and transport tax credits provided the least gains. (C) 2009 Elsevier B.V. All rights reserved.

AB Land surface treatments are often applied after severe wildfires to mitigate runoff and erosion threats. However, questions remain about treatment effectiveness, even as treatment costs continue to rise. We experimentally evaluated the effects of seeding and fertilization treatments on vegetative and total soil cover for two growing seasons after the Pot Peak wildfire in the eastern Cascade Mountains Without treatments. vegetative cover averaged 15% the first year and 27% the second year after wildfire. Fertilization significantly increased vascular plant cover and reduced bare soil area in both years, but differences between low and high fertilization levels were not significant. Fertilization also increased cryptogam cover. Seeding alone was generally ineffective; however, the combination of fertilization with a seed mixture containing the native forb, yarrow (Achillea millefolium L.). produced the highest vascular plant cover and lowest bare soil area. Our results suggest that fertilization may be more effective than seeding, probably providing a degree of protection from erosion, especially the second year after fire However, treatment effectiveness must be evaluated in context against costs and potential ecosystem impacts.

AB We attempted to extend the inference scope of several detailed songbird habitat restoration studies in western Oregon to the broader region through a reanalysis and synthesis of five large-scale management experiments. This previous work demonstrated the importance of understorey vegetation to songbird habitat. However, individual studies have shown conflicting results regarding how vegetation responds to restoration thinning. Understorey vegetation covers 4-6 years after thinning was strongly related to pre-treatment conditions (indexed by the unthinned control treatment). Baseline models that accounted for the pre-treatment conditions showed that herbaceous cover consistently, but only slightly, increased following thinning. Shrub cover, however, tended to decrease following thinning when the pre-treatment cover was > 30 per cent. Each study had limited replication and most had limited geographic and environmental conditions, leading to the inconsistent findings when analysed separately. The reanalysis approach allowed us to test the repeatability of specific finding and demonstrated the applicability of restoration thinning for enhancing habitat in western Oregon.

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

AB We constructed a two-locus database, comprising partial translation elongation factor (EF-1 alpha) gene sequences and nearly full-length sequences of the nuclear ribosomal intergenic spacer region (IGS rDNA) for 850 isolates spanning the phylogenetic breadth of the Fusarium oxysporum species complex (FOSC). Of the 850 isolates typed, 101 EF-1 alpha, 203 IGS rDNA, and 256 two-locus sequence types (STs) were differentiated. Analysis of the combined dataset suggests that two-thirds of the STs might be associated with a single host plant. This analysis also revealed that the 26 STs associated with human mycoses were genetically diverse, including several which appear to be nosocomial in origin. A congruence analysis, comparing partial EF-1 alpha and IGS rDNA bootstrap consensus, identified a significant number of conflicting relationships dispersed throughout the bipartitions, suggesting that some of the IGS rDNA sequences may be non-orthologous. We also evaluated enniatin, fumonisin and moniliformin mycotoxin production in vitro within a phylogenetic framework. Published by Elsevier Inc.

AB The cholinergic theory of aging states that dysfunction of cholinergic neurons arising from the basal forebrain and terminating in the cortex and hippocampus may be involved in the cognitive decline that occurs during aging and Alzheimer's disease. Despite years of research, pharmacological interventions to treat or forestall the development of Alzheimer's disease have primarily focused on enhancing cholinergic transmission, either through increasing acetylcholine (ACh) synthesis or inhibition of the acetylcholinesterase enzyme responsible for ACh hydrolysis. However, recent studies have indicated that dietary supplementation can impact the cholinergic system, particularly during aging. The purpose of the present review is to examine the relevant research suggesting that cholinergic functioning may be maintained during aging via consuming a diet containing polyunsaturated fatty acids (PUFAs). The data reviewed herein indicate that, at least in animal studies, inclusion of PUFAs in the diet can improve cholinergic transmission in the brain, possibly leading to improvements in cognitive functioning.

AB During development, trithorax group (trxG) chromatin remodeling complexes counteract repression by Polycomb group (PcG) complexes to sustain active expression of key regulatory genes. Although PcG complexes are well characterized in plants, little is known about trxG activities. Here we demonstrate that the Arabidopsis SAND (Sp100, AIRE-1, NucP41/75, DEAF-1) domain protein ULTRAPETALA1 (ULT1) functions as a trxG factor that counteracts the PcG-repressive activity of CURLY LEAF. In floral stem cells, ULT1 protein associates directly with the master homeotic locus AGAMOUS, inducing its expression by regulating its histone methylation status. Our analysis introduces a novel mechanism that mediates epigenetic switches controlling post-embryonic stem cell fates in plants.

AB Six cultivars of switchgrass Panicum virgatum L., a plant native to North America that has potential as a bioenergy source, were evaluated for resistance to feeding by the fall armyworm Spodoptera frugiperda (J. E. Smith). Although no mortality was noted, seedlings of the cultivar 'Trailblazer' and older plants of the cultivar 'Blackwell' were among the most resistant to feeding by S. frugiperda. Some field-collected samples from natural habitat were fed upon by S. frugiperda as readily as were the cultivars, while others caused high mortality after 2 days. Enzyme assays indicated relative differences in expression of two peroxidases thought to be involved in insect resistance in maize, but not in two chitinolytic enzymes. Genomic searches based on maize-sequence templates for the aforementioned genes identified homologs in switchgrass. Sequencing of cDNA coding for these genes identified some differences, especially in the cationic peroxidase, which could influence relative activity. These results indicate switchgrass germplasm has varying resistance to fall armyworms which could be a function of gene sequence diversity, as well as of variation in gene expression due to differences in ploidy levels or other factors.

They are not sexually compatible with 4x 4EBN or 2x 2EBN forms of the cultivated potato. In this study, the wild 2x 2EBN Mexican species S. verrucosum (ver) was used as a bridge species to access 2x 1EBN germplasm. Hybrids (V1) were created between ver as a female parent and the 1EBN species S. cardiophyllum, S. chancayense, S. commersonii, and S. trifidum. Most of the V1 hybrids were successfully crossed as females to cultivated 2x 2EBN clones. However, due to stylar barriers, reciprocal crosses were unsuccessful. Additional studies are underway to determine the effectiveness of ver as a bridge to introgress specific traits from 2x 1EBN germplasm into the cultivated potato.

AB The race-specific resistance gene Pi-ta has been effectively used to control blast. disease, one of the most destructive plant diseases worldwide. A single I amino acid change at. the 918 position of the Pi-ta protein was known to determine resistance specificity. To understand the evolutionary dynamics present, we examined sequences of the Pi-ta locus and its flanking regions in 159 accessions composed of seven AA genome Oryza species: O. sativa, O. rufipogon, O. nivara, O. meridionalis, O.glaberrima, O. barthii, and O. glumaepatula. A 3364-bp fragment encoding a predicted transposon was found in the proximity of the Pi-ta promoter region associated with the resistance phenotype. Haplotype network analysis with 33 newly identified Pi-ta haplotypes and 18 newly identified Pi-ta protein variants demonstrated the evolutionary relationships of Pi-ta haplotypes between O. sativa and O. rufipogon. In O. rufipogon, the recent directional selection was found in the Pi-la region, while significant deviation front neutral evolution Was not found in all O. sativa groups. Results of sequence variation in flanking regions around Pi-ta in O. sativa suggest that the size of the resistant Pi-ta introgressed block was M least 5.4 Mb in all elite resistant cultivars but not in the cultivars without Pi-la. These findings demonstrate that the Pi-ta region with transposon and additional plant. modifiers has evolved under an extensive selection pressure during crop breeding.

AB Subgenus Tridentatae (Artemisia, Asteraceae) can be considered a polyploid complex. Both polyploidy and hybridization have been documented in the Tridentatae. Fluorescent in situ hybridization (FISH) and fluorochrome banding were used to detect and analyze ribosomal DNA changes linked to polyploidization in this group by studying four diploid-polyploid species pairs. In addition, genome sizes and heterochromatin patterns were compared between these populations. The linked 5S and 35S rRNA genes are confirmed as characteristic for Artemisia, and a pattern at the diploid level of three rDNA loci located at telomeric positions proved to be typical. Loss of rDNA loci was observed in some polyploids, whereas others showed additivity with respect to their diploid relatives. Genome downsizing was observed in all polyploids. Banding patterns differed depending on the pair of species analysed, but some polyploid populations showed an increased number of heterochromatic bands. FISH and fluorochrome banding were useful in determining the systematic position of Artemisia bigelovii, for which a differential pattern was found as compared with the rest of the group. Additionally, FISH was used to detect the presence of the Arabidopsis-type telomere repeat for the first time in Artemisia.

AB Over the last two and half decades, strong evidence showed that the terrestrial ecosystems are acting as a net sink for atmospheric carbon. However the spatial and temporal patterns of variation in the sink are not well known. In this study, we examined latitudinal patterns of interannual variability (IAV) in net ecosystem exchange (NEE) of CO2 based on 163 site-years of eddy covariance data, from 39 northern-hemisphere research sites located at latitudes ranging from similar to 29 degrees N to similar to 64 degrees N. We computed the standard deviation of annual NEE integrals at individual sites to represent absolute interannual variability (AIAV), and the corresponding coefficient of variation as a measure of relative interannual variability (RIAV). Our results showed decreased trends of annual NEE with increasing latitude for both deciduous broadleaf forests and evergreen needleleaf forests. Gross primary production (GPP) explained a significant proportion of the spatial variation of NEE across evergreen needleleaf forests, whereas, across deciduous broadleaf forests, it is ecosystem respiration (Re). In addition, AIAV in GPP and Re increased significantly with latitude in deciduous broadleaf forests, but AIAV in GPP decreased significantly with latitude in evergreen needleleaf forests. Furthermore, RIAV in NEE, GPP, and Re appeared to increase significantly with latitude in deciduous broadleaf forests, but not in evergreen needleleaf forests. Correlation analyses showed air temperature was the primary environmental factor that determined RIAV of NEE in deciduous broadleaf forest across the North American sites, and none of the chosen climatic factors could explain RIAV of NEE in evergreen needleleaf forests. Mean annual NEE significantly increased with latitude in grasslands. Precipitation was dominant environmental factor for the spatial variation of magnitude and IAV in GPP and Re in grasslands.

AB Excellent winter hardiness, persistence and nutritive value of both kura clover (Trifolium ambiguum M. Bieb.) and reed canarygrass (Phalaris arundinacea L.) suggest that intercropping these species could substitute for lucerne (Medicago sativa L.). The dry matter (DM) yield and nutritive value of herbage, and silage characteristics of kura clover-reed canarygrass (KC-RCG) herbage, were compared to those of lucerne over two growth cycles near Arlington, WI, USA. First and second growths of lucerne and KC-RCG herbage were sampled four times at 1-week intervals and ensiled for 100 d. Yield of DM of the KC-RCG was 0 center dot 23-0 center dot 57 greater than that of lucerne on sampling dates in the first growth cycle, with no differences in DM yield in the second growth cycle. The pH of lucerne silage was lower than that of KC-RCG silage in the first growth, and the opposite occurred in second growth, which was attributed to maturity differences and the proportion of kura clover in the mixture. Lactate concentration was lower in KC-RCG than lucerne silages in both growth cycles. The lucerne and KC-RCG silages had similar in vitro DM digestibility except for the final sampling date in the first growth cycle when neutral-detergent fibre concentration of KC-RCG herbage exceeded 550 g kg-1 DM. Crude protein concentration was greater in lucerne silage than in KC-RCG silage in both growth cycles. Overall, differences in nutritive value and silage fermentation between the two herbages were minimal across growth cycles. These results suggest that a KC-RCG sward is a viable alternative to lucerne in northern environments of the USA where lucerne production may be limited by winter injury or edaphic factors.

AB The effect of sward structure of four temperate grass species on the bite mass of cattle was evaluated. Micro-swards (79 cm x 47 cm; approximately the area of a feeding station) of orchardgrass (Dactylis glomerata L.), quackgrass [Elymus repens (L.) Gould], meadow fescue [Schedonorus pratensis (Huds.) P. Beauv] and reed canarygrass (Phalaris arundinacea L.) were offered to Holstein dairy cows in short-term grazing sessions in 2006 and 2007 using a 4 x 4 Latin square design. Cows were allowed to take fifty bites in each session. Bite mass was calculated by dividing the adjusted change in weight of the micro-sward by the number of bites. Sward surface height, bulk density and distribution of herbage dry matter (DM) in the canopy were measured pre- and post-grazing. Sward structure differed among the grass species within years but bite mass (on a fresh or DM basis) was not affected. Higher surface heights and bulk densities in 2006 compared with 2007 (averaged across grass species) resulted in greater bite masses of DM in 2006. Values were 25 center dot 7 cm vs. 17 center dot 0 cm for surface height; 1219 g m-3 vs. 926 g m-3 for bulk density; and 1 center dot 05 g DM bite-1 vs. 0 center dot 50 g DM bite-1 for 2006 and 2007 respectively. Within the context of this study, differences between years in bite mass, associated with greater changes in sward structure, were more important than differences among grass species.

AB The movement of faecal pathogens from land to surface and ground-water are of great interest because of the public and livestock health implications. Knowledge of canopy structure and how it might be managed to help mitigate nutrient and pathogen movement in pasture is needed to create management practices that balance livestock production with environmental benefits. An experiment was conducted using a rainfall-simulating device to test whether canopy structure of species common to pastures in Appalachia, USA could be managed to influence dispersion of faecal pathogens. Seven pots (30-cm diameter) of white clover, orchardgrass and perennial ryegrass were lined up on horizontal and sloping surfaces under a rainfall simulator. The centre pot was inoculated at the soil surface with 4 x 1010 faecal coliform bacteria (FC) just before rainfall simulation started. The species were maintained under short, moderate and tall canopy management treatments. White clover exhibited the greatest rates of lateral and vertical dispersion of FC into the canopy, especially in the short canopy management treatment following 30 min of rainfall (about 40 mm). Low concentrations of faecal coliform bacteria also dispersed into the canopies of the grass species but the differences in concentration of FC between the grass species were not different. When the proportion of white clover in a pasture is high, the canopy should be relatively taller to reduce the likelihood of infection associated with faecal coliform-contaminated herbage.

AB The ploidy level of H. muluense, a diploid (2n = 2x = 34) and dwarf ornamental ginger species, has been determined and is reported for the first time. Oryzalin and colchicine were successfully used to induce polyploidy in Hedychium muluense in vitro. Embryogenic cell lines were treated with oryzalin (30, 60, or 120 mu M) and colchicine (2.5, 5, or 10 mM) for 24, 48, or 72 h. The control contained no antimitotic agent. Flow cytometry, chloroplast count, and stomatal frequency were more effective and reliable than stomatal length as methods for assessing ploidy. Overall, oryzalin was more effective than colchicine in inducing polyploidy. The highest induction frequency (15%) of tetraploidy was achieved when embryogenic callus was exposed to 60 mu M oryzalin for 72 h. For colchicine, exposure of embryogenic callus to the 2.5 mm colchicine for 24 h was the most effective in creating tetraploid (13%) plants.

AB Loblolly pine (Pinus taeda L.) bark is the primary component of nursery container substrates in the eastern United States. Shortages in pine bark prompted investigation of alternative substrates. The objective of this research was to determine if ground switchgrass (Panicum virgatum L.) could be used for short production-cycle woody crops. Two experiments were conducted using 'Paprika' rose (Rosa L. 'ChewMayTime') potted in 15-cm tall and wide containers. In Expt. 1, substrates were composed of coarse-milled switchgrass (processed in a hammermill with 1.25- and 2.5-cm screens) amended with 0%, 30%, or 50% peatmoss and fertilized with 100, 250, or 400 mg.L(-1) nitrogen (N) from ammonium nitrate. In Expt. 2, substrates were composed of coarse-milled (similar to Expt. 1) or fine-milled switchgrass (processed through a single 0.48-cm screen), amended with 0% or 30% peatmoss, and fertilized with the same N rates as in Expt. 1. Summarizing across both experiments, coarse switchgrass alone had big air space and low container capacity. Fine switchgrass had physical properties more consistent with what is considered normal for nursery container substrates. Switchgrass pH was generally high and poorly buffered against change. Fine switchgrass had higher pH than coarse switchgrass. Tissue analysis of rose grown in switchgrass substrate for 7 to 9 weeks revealed low to moderate levels of calcium and iron, but all other nutrients were within acceptable ranges. Despite varying substrate physical properties and pH levels, all roses at the conclusion of the experiment were of high quality. Switchgrass processed to an appropriate particle size and amended with typical nursery materials should provide a suitable substrate for short production-cycle woody crops.

AB Insufficient fruit retention limits profitability of certain pecan [Carya illinoinensis (Wangenh.) K. Koch] cultivars. The present study examined efficacy of aminoethoxyvinylglycine (formulated as ReTain (R); Valent BioSciences, Libertyville, IL), a natural ethylene inhibitor, for increasing crop-load through increased fruit retention in pecan trees grown at three distinct locations within the U.S. pecan belt. Several years of field studies found that timely postpollination ReTain (R) sprays [132 mg.L(-1) a.i. (11.7 oz./acre)] to canopies could increase fruit retention of 'Desirable' and increase crop yield by 16% to 38% in trees carrying a "moderate to heavy" crop. ReTain (R) did not detectably increase fruit retention on trees carrying a "light" crop-load. The ReTain (R)-associated increase in yield of "heavy" crop-load trees did not necessarily decrease subsequent year yield. ReTain (R) appears to offer commercial potential as a crop-load management tool for 'Desirable' through regulation of Stage II drop (i.e., June-drop), but may not be efficacious for all cultivars.

AB Seedling peach (Prunus persica Batsch) and clonal peach-almond hybrids are popular rootstock choices for commercial almond growers in California. In this study, clonal replicates of peach and almond [P. dulcis (Mill.) D.A. Webb] rootstock germplasm and a first-generation peach-almond hybrid created from them were challenged with Xylella fastidiosa isolate M23. Clonal replicates were needle-inoculated with M23 and maintained in a greenhouse environment for a growing season. Typical almond leaf scorch disease symptoms began to develop on M23-inoculated almonds I I weeks after inoculation. No leaf scorch symptoms were observed on M23-inoculated peach or peach-almond hybrids. Quantitative real-time polymerase chain reaction revealed consistent levels of X. fastidiosa DNA among inoculated almond replicates, whereas X.fastidiosa DNA was undetectable in replicates of peach-almond hybrids. A trace level of X. fastidiosa DNA was detected in a single peach replicate, and statistical analysis demonstrated that this level differed significantly (P < 0.001) from that detected in almond replicates. Selected almonds were further sampled sequentially along their meristematic axes to examine bacterial titer throughout the trees. Selected almond trees differed significantly (P = 0.036) in bacterial titer, but no significant differences were noted in levels of X fastidiosa from different vertical sections of the main growth axes. The results suggest that peach and peach-almond hybrid rootstock germplasm used by commercial almond tree nurseries in California are not primary inoculum sources for X. fastidiosa-induced diseases.

AB The expression of gastrodianin antifungal protein (GAFP) in a form of its VNF isoform increases tolerance to Phytophthora root rot (Phytophthora cinnamomi) and the root-knot nematode (Meloidogyne incognita) in transgenic plum lines. However, nothing is known about the potential of the GAFP lectin to confer disease resistance to the ring nematode, Mesocriconema xenoplax, in plum. Three transgenic plum lines (4I, 4J, and 5D) expressing gafp-1 under the control of CaMV 35S promoter sequence were evaluated for their response to M. xenoplax in the greenhouse. All plum lines were rated as hosts of M. xenoplax. Among the individual plum lines tested, the number of M. xenoplax per gram of dry roots was lowest in the rhizosphere of transgenic line 5D, intermediate in that of the nontransformed control line, and greatest in line 4J. The results of this study indicate that the comparisons of the final soil densities (Pf) of adult and juvenile M. xenoplax expressed as nematodes per gram of dry roots provide a better measure of the nematode carrying capacity by the tested lines than Pf values referred to as number of M. xenoplax/100 cm(3) soil.

AB Alternatives to sulfur dioxide to maintain quality of table grapes, including various combinations of rachis removal, chlorinated wash, hot water treatment, and modified atmosphere packaging, were explored in this study. Grapes were prepared by cutting off the rachis 1 to 2 mm from the fruit or by keeping the clusters intact. After initial preparation, short-stem and cluster grapes were subjected to chlorinated wash and/or hot water (45 degrees C, 8 min) treatment and packaged in plastic trays sealed with a gas-permeable film. The treated grapes as well as the commercially packed grapes (COM) in their original packages were stored at 5 degrees C for up to 4 weeks. Hot water treatment resulted in significantly (P < 0.05) higher oxygen retention and lower carbon dioxide accumulation in package headspaces, maintained a firmer texture, higher overall visual quality, lower decay rate, and lower microbial populations than other treatments or COM during the entire storage period. Grapes that were cut from the rachis and treated with hot water and chlorine maintained the highest quality for 4 weeks with the least decay among all treatments. A chlorine prewash treatment significantly (P < 0.05) reduced microbial populations on cluster grapes and maintained better overall quality. Conventional COM grapes developed dark decay and lost turgidity and were of unacceptable quality at 28 days of storage.

AB Huanglongbing (HLB) is a devastating disease of citrus and threatens the citrus industry worldwide. The suspected causal agent of the disease is a phloem-limited bacterium of the genus Candidatus Liberibacter transmitted through insect vector or grafting with diseased budwood. Currently, most seed source trees for citrus rootstock propagation are located outdoors and unprotected from disease transmission. In addition, fruit from HLB-affected scion varieties in Florida containing seeds enter the commercial trade and move into other citrus-growing areas. The objective of this study was to determine how Ca. L. asiaticus infection affects seed quality and seedling development and whether the disease appears in seedlings grown from infected fruit. Two experiments were conducted involving thousands of seedlings produced from seeds from infected rootstock seed source trees and 'Valencia' sweet orange trees, respectively. Infection of trees and fruit with Ca. L. asiaticus significantly reduced seed weight, seed germination, and seedling height. Seedlings did not develop symptoms typical of HLB throughout the experiment. Polymerase chain reaction (PCR) analysis initially identified two of 686 rootstock seedlings and three of 431 sweet orange seedlings positive for the pathogen when they were very young. Resampling and PCR analysis of these five seedlings at older ages consistently indicated they were negative for the pathogen and none of these plants ever developed symptoms of HLB. It is suggested that Ca. L. asiaticus may have been translocated into some part of the embryo during seed development but that it was not present in cells or tissue, which permitted replication or disease development as the seedling grew.

AB Split-resistant and split-susceptible rabbiteye blueberry fruit were evaluated at all stages of development to determine "water uptake thresholds" by soaking in distilled water. Weight increase after soaking was measured, and percent weight gain was calculated to take into consideration the weight increase of the fruit from development. The ratio of percent increase in volume to weight increase resulting from water uptake was calculated. Ratios of percent water uptake to weight increase between split-susceptible 'Tifblue' and split-resistant 'Premier' blueberries were found to be similar. The split-susceptible 'Tifblue' had a 1.6 g/50 fruit increase with a 1.7% water uptake and a ratio of 1.08. 'Premier' had a higher weight increase with 3.3 g/50 fruit and also a higher percentage of water uptake at 3.6% providing a ratio of 1.09. Although both absorbed water at a constant rate shown by a linear increase of weight increase over time, 'Premier' absorbed a significantly greater amount of water than did 'Tifblue' yet remained intact and did not split.

AB Variants of a hexanucleotide repeat polymorphism in the promoter of the 5-lipoxygenase (5-LO) gene have been associated with cardiovascular disease traits in humans, which may be due, at least in part, to differential expression of the at-risk alleles. To more fully characterize these variants, we carried out gene expression and DNA methylation studies in primary leukocytes from healthy individuals carrying various 5-LO promoter alleles. Regardless of genotype, 5-LO and 5-LO-activating protein (FLAP) gene expression was higher in granulocytes compared with monocytes and lymphocytes, whereas leukotriene A(4) hydrolase (LTA4H) expression was higher in monocytes. In all three leukocyte populations, 5-LO mRNA levels were positively correlated with those of FLAP and LTA4H, with the highest correlation observed in granulocytes. In lymphocytes, individuals homozygous for the shorter 3 and 4 repeat alleles had between 20-35% higher 5-LO, FLAP and LTA4H expression compared with homozygous carriers of the wild-type 5 repeat allele (P = 0.03-0.0001). DNA methylation analysis of four CpG islands in a 1500 bp region encompassing the 5-LO promoter and the first similar to 100 bp of intron 1 revealed relatively low overall DNA methylation across all genotypes and leukocyte populations. However, analysis of the promoter repeats themselves demonstrated that, regardless of cell population, the 4 allele was methylated approximately twice as much as the 3 allele (P < 0.0001). Our results demonstrate that, in lymphocytes, the shorter repeat alleles of the 5-LO promoter lead to higher gene expression, which may be regulated through differential DNA methylation of the CpGs located within these repeats.

AB Low plasma B-vitamin levels and elevated homocysteine have been associated with cancer, cardiovascular disease and neurodegenerative disorders. Common variants in FUT2 on chromosome 19q13 were associated with plasma vitamin B(12) levels among women in a genome-wide association study in the Nurses' Health Study (NHS) NCI-Cancer Genetic Markers of Susceptibility (CGEMS) project. To identify additional loci associated with plasma vitamin B(12), homocysteine, folate and vitamin B(6) (active form pyridoxal 5'-phosphate, PLP), we conducted a meta-analysis of three GWA scans (total n = 4763, consisting of 1658 women in NHS-CGEMS, 1647 women in Framingham-SNP-Health Association Resource (SHARe) and 1458 men in SHARe). On chromosome 19q13, we confirm the association of plasma vitamin B(12) with rs602662 and rs492602 (P-value = 1.83 x 10(-15) and 1.30 x 10(-14), respectively) in strong linkage disequilibrium (LD) with rs601338 (P = 6.92 x 10(-15)), the FUT2 W143X nonsense mutation. We identified additional genome-wide significant loci for plasma vitamin B(12) on chromosomes 6p21 (P = 4.05 x 10(-08)), 10p12 (P-value=2.87 x 10(-9)) and 11q11 (P-value=2.25 x 10(-10)) in genes with biological relevance. We confirm the association of the well-studied functional candidate SNP 5,10-methylene tetrahydrofolate reductase (MTHFR) Ala222Val (dbSNP ID: rs1801133; P-value=1.27 x 10(-8)), on chromosome 1p36 with plasma homocysteine and identify an additional genome-wide significant locus on chromosome 9q22 (P-value=2.06 x 10(-8)) associated with plasma homocysteine. We also identified genome-wide associations with variants on chromosome 1p36 with plasma PLP (P-value=1.40 x 10(-15)). Genome-wide significant loci were not identified for plasma folate. These data reveal new biological candidates and confirm prior candidate genes for plasma homocysteine, plasma vitamin B(12) and plasma PLP.

AB St. Augustinegrass is one of the most important warm season turfgrasses in the southern United States because of its shade tolerance. Most cultivars are diploids (2n = 2x = 18) and are susceptible to various diseases and insects. Polyploid cultivars in the species have some resistance to pests, but most lack cold tolerance. In this study, eight polyploid genotypes were crossed with six diploid cultivars to transfer pest resistance to the diploids. Because interploid crosses often result in aborted seed, it was necessary to use in vitro techniques. Using embryo rescue, 268 plants were recovered from 2,463 emasculated and pollinated florets (10.88% crossability). Because of the heterogeneous nature of the species, these purported hybrids could not be verified by phenotype. DNA markers were used for hybrid identification. A subset of 25 plants from crosses between the aneuploid cultivar Floratam (2n = 4x = 32) and five diploid cultivars were analyzed using 144 expressed sequence tags-simple sequence repeats (EST-SSRs) developed from buffelgrass cDNA sequence data. Chi-square tests for paternal-specific markers revealed that all analyzed progeny were true F(1) hybrids and none originated from self-fertilization or unintended outcrossing. In addition to identifying DNA polymorphism, the EST-SSRs revealed that genetic variation exists among all analyzed cultivars and is not partitioned between ploidy levels. The findings demonstrate that these embryo rescue techniques will enable the entire spectrum of St. Augustinegrass genetic variation to be better used through the recovery of interploid hybrids.

AB The influence of the nutrient composition of plant tissue culture media on axillary shoot proliferation and their preconditioning effect on subsequent adventitious shoot regeneration from pear leaves was investigated. The goal was to improve both micropropagation and regeneration of 'Bartlett' and 'Beurre Bosc' pear cultivars. Driver-Kuniyuki walnut (DKW) and Quoirin and Lepoivre (QL) nutrient media were found to be superior to Murashige and Skoog (MS) and Woody Plant Medium (WPM) for axillary shoot proliferation. Shoots on WPM exhibited some chlorosis. Axillary shoot culture on DKW would be preferred to that on QL due to the production of excessively short thin shoots on the latter medium. DKW also was superior to QL and MS for production of young expanding leaves for use as explants in adventitious regeneration. Leaf explants derived from shoot proliferation cultures grown on DKW or QL media produced more adventitious shoots than leaf explants from MS.

AB Virtually nothing is known about disease resistance in solitary bees, so expressed sequence tag (EST) databases were developed to search for immune response genes in the alfalfa leafcutting bee. We identified 104 putative immunity-related genes from both healthy and pathogen-challenged bee larvae, and 12 more genes using PCR amplification. The genes identified coded for proteins with a wide variety of innate immune response functions, including pathogen recognition, phagocytosis, the prophenoloxidase cascade, melanization, coagulation and several signalling pathways. Some immune response genes were highly conserved with honey bee genes, and more distantly related to other insects. The data presented provides the first analysis of immune function in a solitary bee and provides a foundation for the further analysis of gene expression patterns in bees.

AB As part of the USA's National Strategy for Pandemic Influenza, an Interagency Strategic Plan for the Early Detection of Highly Pathogenic H5N1 Avian Influenza in Wild Migratory Birds was developed and implemented. From 1 April 2006 through 31 March 2009, 261 946 samples from wild birds and 101 457 wild bird fecal samples were collected in the USA; no highly pathogenic avian influenza was detected. The United States Department of Agriculture, and state and tribal cooperators accounted for 213 115 (81%) of the wild bird samples collected; 31, 27, 21 and 21% of the samples were collected from the Atlantic, Pacific, Central and Mississippi flyways, respectively. More than 250 species of wild birds in all 50 states were sampled. The majority of wild birds (86%) were dabbling ducks, geese, swans and shorebirds. The apparent prevalence of low pathogenic avian influenza viruses during biological years 2007 and 2008 was 9.7 and 11.0%, respectively. The apparent prevalence of H5 and H7 subtypes across all species sampled were 0.5 and 0.06%, respectively. The pooled fecal samples (n = 101 539) positive for low pathogenic avian influenza were 4.0, 6.7 and 4.7% for biological years 2006, 2007 and 2008, respectively. The highly pathogenic early detection system for wild birds developed and implemented in the USA represents the largest coordinated wildlife disease surveillance system ever conducted. This effort provided evidence that wild birds in the USA were free of highly pathogenic avian influenza virus (given the expected minimum prevalence of 0.001%) at the 99.9% confidence level during the surveillance period.

AB Cross prediction trials or progeny tests for family selection are commonly employed at the beginning of each breeding cycle in clonally propagated crops such as sugarcane (Saccharum spp. Hybrid). When selecting sugarcane families, the factors affecting variability between and within those families should be considered. This research examined the influence of family and intra-row, plant spacing oil the efficiency of the index selection procedure as a method of simultaneous improvement of a population for multiple traits at the first selection stage of the Louisiana Sugarcane Variety Development Program (LSVDP). Therefore, the main objective of this study was to develop a selection index for selecting sugarcane families within the LSVDP. Expected genetic advance values for plant weight were greater in the wide-spaced indices than in the narrow-spaced ones. Irrespective of plant spacing, selection indices revealed that all increase in efficiency was observed over direct selection for plant weight when all jour plant weight contributing traits were included along with plant weight. The efficiency in selection tended to decrease when indices were based oil fewer traits. Nevertheless, a few of the indices that included two traits had relative efficiencies comparable to the best indices and the majority certainly was as effective as direct selection for plant weight.

Region, farm size, financial situation, and production intensity measures impact system choice. Analysis follows to determine the impact of production system on enterprise profitability. Region, farm size, and demographic variables impact profitability, as does system choice: semi-pasture-based operations were less profitable than conventional operations on an enterprise, per hundredweight of milk produced basis. Significant differences were not found in the profitability of pasture-based operations versus those using other systems.

AB Organic farmers face heightened pressure in developing a portfolio of different marketing channels and in bargaining competitively with increasingly sophisticated marketing participants in the supply chain for organic products. This research assists producers by identifying specific farm and demographic factors that enhance earnings given the choice of marketing outlet. The two significant selectivity coefficients confirm that organic earnings when marketing through a single outlet are biased upward since farmers who are better suited to market through multiple outlets have already moved away from this marketing strategy. An accurate evaluation of the projected earnings from any marketing strategy must account for selectivity effects.

ID COUNT DATA; IMPACT
AB Distance sampling is a survey technique for estimating the abundance or density of wild animal populations. Detection probabilities of animals inherently differ by species, age class, habitats, or sex. By incorporating the change in an observer's ability to detect a particular class of animals as a function of distance, distance sampling leads to density estimates that are comparable across different species, ages, habitats, sexes, and so on. Increasing interest in evaluating the effects of management practices on animal populations in an experimental context has led to a need for suitable methods of analyzing distance sampling data. We outline a two-stage approach for analyzing distance sampling data from designed experiments, in which a two-step bootstrap is used to quantify precision and identify treatment effects. We illustrate this approach using data from a before-after control-impact experiment designed to assess the effects of large-scale prescribed fire treatments on bird densities in ponderosa pine forests of the southwestern United States.

AB The objective of this experiment was to characterize the effect of the synthetic opioid Syndyphalin-33 (SD-33) on immune cell populations with and without a concurrent inoculation with a common enteric pathogen, Salmonella enterica Typhimurium (SALM) in recently weaned pigs. On day 0, pigs (8 barrows and 6 gilts, 24 1 days of age, 8.43 +/- 0.82 kg) were weaned and fitted with jugular catheters. The following day, pigs were administered either SD-33 (0.5 mu mol kg(-1), given i.m.) or saline (VEH; 0.5 mL, given i.m.) and SALM (oral gavage of 5 x 10(9) CFU) or sterile broth (CON; 3 mL oral gavage) in a factorial arrangement with 4 treatment groups: VEH + CON (n = 4), SD-33 + CON (n = 3), VEH + SALM (n = 3) and SD-33 + SALM (n = 4). There were no differences in Feed Intake (FI) or Body Weight (BW) among the SALM treated animals over time (p>0.05). Cumulatively, FI among the SD-33 + CON pigs was greater(p<0.05) compared to the SD-33 + SALM pigs. White Blood Cell (WBC) populations increased (p<0.05) over the 4 days postinjection period. On day 2 postchallenge, circulating neutrophils and lymphocytes were lower (p<0.05) in VEH + SALM but not in SD-33 + SALM pigs relative to VEH + CON and SD-33 + CON pigs, demonstrating the ability of SD-33 to abrogate the affect of Salmonella. Also, on day 2 postchallenge, circulating monocyte populations were greater (p<0.05) in pigs receiving SD-33 relative to controls regardless of SALM treatment. The results of this preliminary study suggest that the opioid SD-33 may modulate the immune axis in recently weaned pigs.

AB The influence of additive and nonadditive genetic effects and temperament on 4 postweaning feed intake and growth traits was evaluated in a group of 581 bull, heifer, and steer calves born in 3 Florida herds in 2006 and 2007. Calves had breed compositions ranging from 100% Angus (A) to 100% Brahman (B). They were randomly allocated to 24 pens each year by herd (Brooksville, Gainesville, Marianna, FL), sire group (A, 3/4 A 1/4 B, Brangus, 1/2 A 1/2 B, 1/4 A 3/4 B, and B), and sex (bull, heifer, and steer) in a GrowSafe automated feeding facility at Marianna. Calves were fed a concentrate diet during the 21-d adjustment and the 70-d trial periods. Individual feed intakes were recorded daily, and BW, chute scores, and exit velocities were recorded every 2 wk. Traits were phenotypic daily residual feed intake (RFI), mean daily feed intake (DFI), mean daily feed conversion ratio (FCR), and postweaning BW gain. Phenotypic RFI was computed as the difference between actual and expected feed intakes. Calves were assigned to 3 RFI groups: high (RFI greater than 0.9 kg of DM/d), low (RFI less than -0.9 kg of DM/d), and medium (RFI between mean +/- 0.9 kg of DM/d; SD = 1.8 kg of DM/d). The mixed model included the fixed effects of contemporary group (herd-year-pen), RFI group (except when trait was RFI), age of dam, sex of calf, age of calf, B fraction of calf, heterozygosity of calf, mean chute score, and mean exit velocity. Brahman fraction and heterozygosity of calf were nested within sex of calf for RFI and within RFI group for DFI, FCR, and postweaning BW gain. Random effects were sire and residual. Feed efficiency tended to improve (decreased RFI) as the B fraction increased. However, calves required larger amounts of feed per kilogram of BW gain (larger FCR) as the B fraction increased. Postweaning BW gain tended to decrease as the B fraction increased. Temperament traits were unimportant for all traits except exit velocity for DFI, suggesting perhaps a lack of variation for temperament traits in this herd, or that calves became accustomed to the level of handling pre- and postweaning, thus decreasing behavioral differences among them.

AB The energy value of crude glycerin from different biodiesel production facilities was determined in nursery pigs (initial BW of 10.4 kg) to predict apparent DE and ME based on the composition of crude glycerin. Dietary treatments consisted of a basal diet, or diets containing crude glycerin from various biodiesel production facilities supplemented in the diet at approximately 9.1%. Because of bulk density differences, 2 glycerin products were supplemented at either 7.7 or 6.9%. In addition, soybean oil and lard were included at 6.7% as 2 dietary treatments to serve as positive controls. Each diet was fed twice daily to pigs in individual metabolism crates. After a 6-d adjustment period, a 4-d balance experiment was conducted. During the collection period, feces and urine were collected daily and stored at 0 degrees C until analysis. The GE of each test ingredient and diet and of urine and fecal samples from each pig were determined by isoperibol bomb calorimetry. The DE and ME values of crude glycerol were estimated by difference, whereby the DE and ME content of the basal diet was subtracted from the complete diet containing the test ingredient. Gross energy, DE, and ME of US Pharmacopeia grade glycerin were determined to be 4,325, 4,457, and 3,682 kcal/kg, respectively. In contrast, GE of the crude glycerin samples ranged from 3,173 to 6,021 kcal/kg, DE ranged from 3,022 to 5,228 kcal/kg, and ME ranged from 2,535 to 5,206 kcal/kg, reflecting the content of glycerol, methanol, and FFA in the crude glycerin. The GE, DE, and ME of soybean oil and lard were determined to be 9,443, 8,567, and 8,469 kcal/kg, and 9,456, 8,524, and 8,639 kcal/kg, respectively. The stepwise regression prediction of the ME in crude glycerin exhibited R(2) of only 0.41 [ME, kcal/kg (as-is basis) = (37.09 x % of glycerin) + (97.15 x % of fatty acids)], whereas prediction of GE achieved an R2 of 0.99 pGE, kcal/kg (as-is basis) = -236 + (46.08 x % of glycerin) + (61.78 x % of methanol) + (103.62 x % of fatty acids)]. On average, the ME of crude glycerin was 85.4% of its GE (SE 5.3) and did not differ by glycerin source. The data provided in these experiments indicate that crude glycerin is a valuable energy source, with its GE concentration dependent on the concentration of glycerin, methanol, and fatty acids, and with ME as a percentage of GE averaging 85.4%.

AB Three 2.4-ha wheat (Triticum aestivum L.) fields were used to test the effects of maturity at harvest (boot vs. dough) and preservation method (hay vs. silage) on forage yield, chemical composition, and animal performance when fed in mixed diets. Forages were incorporated into 4 diets in a 2 x 2 factorial arrangement of treatments with hominy feed, soybean hulls, and cottonseed meal as the primary concentrate ingredients. In Exp. 1 diets contained 20% wheat forage (DM basis) and were fed to 96 beef calves (n - 48 steers and 48 heifers; initial BW 229 +/- 6.0 kg) in 12 mixed-sex pens. In Exp. 2 diets contained 40% wheat forage (DM basis) and were fed to beef steers (n - 48; initial BW 198 +/- 6.8 kg) in 12 pens. These diets were also individually fed to 32 calves (Exp. 1, n - 16, BW - 187 +/- 9.4 kg; Exp. 2, n - 16 calves, BW - 160 +/- 8.2 kg) to determine DM and NDF digestibility and gastrointestinal tract passage kinetics. Advanced maturity increased (P < 0.01) DM yield, decreased (P < 0.01) CP concentrations, and tended (P - 0.10) to increase non-fiber carbohydrate concentrations, but did not affect (P >= 0.22) NDF, ADF, or TDN concentrations. Maturity at harvest, preservation method, or their interaction did not affect (P >= 0.15) ADG when wheat forage was fed as 20 or 40% of the diet. When calves were fed the 40% wheat forage diets, maturity at harvest did not affect (P >= 0.27) DMI or G: F. Calves fed 40% hay diets consumed more (P - 0.04) feed DM as a percentage of BW than calves fed silage diets, but tended (P - 0.09) to be less efficient. With 20 or 40% wheat forage diets, there were no differences (P >= 0.13) in passage rate, ruminal retention time, or fecal output due to maturity or preservation method. Digestibility of DM tended (P - 0.07) to be greater for silage than hay diets when fed in 20% wheat forage diets. Dry matter and NDF digestibility of 40% boot-stage wheat forage diets were greater (P < 0.01) than diets containing forage harvested in dough stage. Forty percent hay diets also tended (P - 0.07) to have greater DM digestibility, and NDF digestibility was greater (P < 0.01) compared with silage diets. Although differences in performance were not noted in the present experiments, increased maturity at harvest and preservation as silage can cause differences in DMI and digestibility of DM and NDF in diets containing 40% wheat forage.

AB Previous research indicates that early weaning before shipment can reduce transportation-induced increases in acute-phase proteins (APP) and can increase feedlot performance in beef calves. These data suggest that the combination of weaning and transport stress may compromise the immune system of calves, thus hindering subsequent performance and health. Therefore, our objective was to determine if the innate immune response of early weaned calves (EW; 80 d of age) differed from normal-weaned calves (NW; 250 d of age) in response to an endotoxin challenge. Eighteen Brahman x Angus calves (8 and 10 EW and NW, respectively; 233 +/- 5 kg of BW) were used. Calves were maintained on pasture with supplement and then moved into individual pens for 1 wk of acclimation before the start of the study. Calves were fitted with an indwelling jugular catheter 1 d before LPS challenge (0 h; 1.0 mu g/kg of BW, intravenously). Blood samples were collected at 30-min intervals from-2 to 8 h. Serum samples were stored at-80 degrees C until analyzed for cortisol, tumor necrosis factor-alpha (TNF), IL-1 beta, IL-6, interferon-gamma (IFN), ceruloplasmin, and haptoglobin. Whereas LPS increased serum cortisol (P <= 0.001), no weaning age effect (P >= 0.15) was observed. A weaning age x time interaction (P <= 0.04) was observed for TNF, IL-1, IL-6, and ceruloplasmin such that concentrations of these indices were greater in the NW compared with EW calves. For haptoglobin, a weaning age effect (P <= 0.03) was observed with NW calves having greater average haptoglobin concentrations compared with EW calves. Interestingly, the weaning age x time interaction (P <= 0.001) for IFN revealed greater IFN in EW compared with NW calves. Based upon these data, the innate immune system of EW calves appears to be more competent in responding to immune challenge compared with that of NW calves. Additionally, the differential IFN response indicates that the immune system of EW calves may be more effective at recognizing and eliminating endotoxin. These data suggest that an altered innate immune system may be one of the factors responsible for the improved feedlot performance previously reported in EW calves.

AB Assimilating accurate behavioral events over a long period can be labor-intensive and relatively expensive. If an automatic device could accurately record the duration and frequency for a given behavioral event, it would be a valuable alternative to the traditional use of human observers for behavioral studies. Therefore, the objective of this study was to determine the accuracy in the time spent at the waterer and the number of visits to the waterer by individually housed nursery pigs between human observers scoring video files using Observer software (OBS) and an automatic water meter Hobo (WM, control) affixed onto the waterline. Eleven PIC USA genotype gilts (22 perpendicular to 2 d of age; 6.5 perpendicular to 1.4 kg of BW) were housed individually in pens with ad libitum access to a corn-based starter ration and one nipple waterer. Behavior was collected on d 0 (day of weaning), 7, and 14 of the trial using 1 color camera positioned over 4 attached pens and a RECO-204 DVR at 1 frame per second. For the OBS method, 2 experienced observers recorded drinking behavior from the video files, which was defined as when the gilt placed her mouth over the nipple waterer. Data were analyzed using nonparametric methods and the general linear model and regression procedures in SAS. The experimental unit was the individual pen housing 1 gilt. The GLM model included the method of observation (WM vs. OBS) and time (24 h) as variables, and the gilt nested within method was used as the error term. Gilts consumed more water (P - 0.04) on d 14 than on d 0. The time of day affected (P < 0.001) the number of visits and the time spent at the waterer regardless of the method. However, the OBS method underestimated (P < 0.001) the number of visits to the waterer (3.48 +/- 0.33 visits/h for OBS vs. 4.94 +/- 0.33 for WM) and overestimated (P < 0.001) the time spent at the waterer (22.6 +/- 1.46 s/h for OBS vs. 13.9 +/- 1.43 for WM) compared with WM. The relationship between the 2 methods for prediction of time spent at the waterer and number of visits made by the gilts was weak (R(2) = 0.56 and 0.69, respectively). Collectively, these data indicate that the use of the traditional OBS method for quantifying drinking behavior in pigs can be misleading. Quantifying drinking behavior and perhaps other behavioral events via the OBS method must be more accurately validated.

Using a mark-release-recapture method with Colorado potato beetle [Leptinotarsa decemlineata (Say)], we compared the tenure time and dispersal of marked insects released within experimental potato fields to those released at the field borders in three trials in summer 2006. Plots within fields had rye, vetch or no plant residues. Movement of marked Colorado potato beetles into the tilled plots was significantly higher than into vetch or rye cover treatments. The abundance of naturally occurring beetles in the three cover treatments followed the general patterns of the number of marked immigrants over all releases. Marked beetles released inside the potato field tended to move along the release row rather than across rows; this pattern was stronger for the tilled treatment than for the two mulch cover treatments. Marked beetles disappeared from within the potato fields differently, depending on the cover crop treatment, but the patterns were not consistent over the season. Incorporation of dispersal patterns into pest management strategies should improve methods of pest population regulation, especially for the initial colonization of fields.

AB The magnitude and distribution of incoming shortwave solar radiation (SWY) has significant influence on the productive capacity of forest vegetation. Models that estimate forest productivity require accurate and spatially explicit radiation surfaces that resolve both long-and short-term temporal climatic patterns and that account for topographic variability of the land surface. This paper presents a validation of monthly average total (SW down arrow(t)) and diffuse (SWY down arrow(f)) incoming solar radiation surfaces taken from North American Regional Reanalysis (NARR) data and Moderate Resolution Imaging Spectroradiometer (MODIS) satellite imagery for a mountainous region of the Pacific northwestern United States and Canada. A topographic solar radiation model based on a regionally defined clearness index was used to downscale the 32-km NARR SW down arrow(t) surfaces to 1 km, resulting in surfaces that better matched the spatial resolution of MODIS, as well as accounted for elevation and terrain effects including shadowing. Validation was carried out using a series of ground station measurements (n = 304) collected in 2003. The results indicated that annually, the NARR and MODIS SW down arrow(t) surfaces were both in strong agreement with ground measurements (r = 0.98 and 0.97), although the strength and bias of the relationships varied considerably by month. Correlations were highest in winter, early summer, and fall and lowest in spring. The NARR and MODISSW down arrow(df) surfaces displayed poorer agreement with ground measurements (r = 0.89 and 0.79), the result of some months having negative correlations. The correlation and spatial structure between NARR and MODIS SW down arrow(t) surfaces was enhanced by topographic correction, resulting in more consistent input radiation surfaces for use in broad-scale forest productivity modeling.

AB Dietary amino acid requirements are influenced by environmental conditions. Two experiments examined growth responses of male Ross x Ross TP 16 broilers fed diets varying in digestible Lys concentrations from 14 to 28 d of age under different environmental conditions. Experiment 1 was conducted in July 2007, whereas experiment 2 was initiated during October 2007. In each experiment, dietary treatments consisted of 6 concentrations of digestible Lys and a positive control. Digestible Lys ranged from 0.90 to 1.25% in increments of 0.07% and from 0.92 to 1.32% in increments of 0.08% for experiments 1 and 2, respectively. Linear and quadratic improvements were observed for BW gain and feed conversion in experiments 1 and 2, respectively. In experiment 2, the digestible Lys requirement was estimated at 1.19% based on a quadratic broken-line model and a quadratic regression equation. Digestible Lys intakes that corresponded to the optimal digestible Lys response based on a dietary percentage were estimated at 1,280 and 1,404 mg/d for experiments 1 and 2, respectively. These results suggest that the need for dietary Lys varied considerably with broilers reared in environmental conditions simulating winter vs. summer production when expressed on a digestible Lys intake basis.

AB Fire is an important driver of ecological pattern and process in grasslands worldwide, although its role in semi-arid systems is less well known. We used published studies and new experimental research to 1) provide a synthesis of existing knowledge of fire in the semi-arid grasslands of the North American Great Plains, and 2) assess the degree of similarity in semi-arid and mesic grassland responses to fire in this region. Based on published studies, burning has neutral to negative effects on aboveground productivity in semi-arid grasslands and variable effects on plant communities. To more rigorously assess fire effects, replicated experimental plots were established in ungrazed shortgrass steppe in northern Colorado and prescribed spring fire was applied in 2006 and 2007, 2006 only, or not at all. Aboveground net primary productivity decreased or remained unchanged with burning. Plant community changes included increases in perennial forbs, decreases in annual grasses and a positive response in annual forbs to the combination of fire and a wet spring in 2007. Combined, these results indicate that post-fire changes in productivity in semi-arid grasslands are neutral to negative, in contrast to positive responses in mesic grasslands, and not strongly negative as previously assumed.

AB Domestic grazing animals that congregate around watering points in and rangelands create clearly-defined trampling-induced grazing gradients. Grazing and trampling alter soil and vegetation condition, often leading to substantial reductions in ecological function. We measured foraging pits and mounds created by native soil foraging animals over 12 months at three watering points in a Chihuahuan Desert grassland, and hypothesized that the density and cover of their disturbances would increase with increasing distance from water. We recorded an average of 3756 disturbances ha(-1) and cover of 34.18 m(2) ha(-1) across the grazing gradients, which comprised mainly pits (43%) and mounds (25%) of heteromyid rodents, ants and spiders. Soil turnover was estimated at 1.43 m(3) ha(-1). We detected no differences in density, cover, soil volume or composition of disturbances in relation to distance from water, but there were significant, though ill-defined, differences across the five sampling periods, with generally more activity in the warm-wet months. Small animal-created mounds and pits are important sources of soil and sinks for litter within grazing gradients, and may represent the only sites where plants can establish given a relaxation in grazing pressure.

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

AB From 2000 through 2003 we used semiochemical-baited traps in northeastern Minnesota, USA, to assess changes in assemblages of subcortical forest insects after a catastrophic wind storm in 1999 and subsequent (1999-2000) fuel-reduction activities (salvage-logging and prescribed-burning). We determined the regional efficacy of fifteen semiochemical blends (pheromones and kairomones) as attractants for target and non-target subcortical insect species (Coleoptera: Anthribidae, Buprestidae, Cerambycidae, Cleridae, Cucujidae, Curculionidae, Histeridae, Nemonychidae, Salpingidae, Scolytidae, Tenebrionidae, and Hymenoptera: Siricidae). During the four summers, we trapped 86,471 subcortical insects (143 species) in baited and unbaited Lindgren funnel traps, and 500 beetles (44 species) in baited and unbaited pitfall traps. We report 23 new state collection records of subcortical insects from Minnesota. Trap catches of subcortical insects were greatest in the wind-disturbed areas 2 years after the event, and declined thereafter. Similar trends were observed for subcortical insects in the burned areas. Both wind-disturbance and burning increased the subcortical insect species richness and diversity on the landscape. The subcortical insect species compositions of the salvaged and burned forest areas differed from those of the undisturbed and wind-disturbed areas. Trap catches of subcortical insects in response to semiochemical treatments also varied with year of sampling and land-area treatment. The greatest diversity of subcortical beetle species was in traps baited with attractants for the scolytids, Dendroctonus valens [(+)-alpha-pinene and (-)-beta-pinene] and Dryocoetes spp. [exo-brevicomin and (-)-alpha-pinene], perhaps reflecting the generic nature of the baits. The most distinct species compositions were collected in response to the woodborer and Dendroctonus simplex baits, whereas the species compositions in traps with the D. valens and Dryocoetes spp. baits, and the unbaited funnel trap were the most similar. The variation in trap catch with time and across landscapes suggests that the responses of subcortical insects to semiochemicals are more complex than previously appreciated.

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

AB Females of the pine false webworm Acantholyda erythrocephala (L) produce the sex pheromone (Z)-6,14-pentadecadienal, which attracts flying males in the field. By using gas chromatography coupled with electroantennographic detection (GC-EAD) and mass spectrometry (GC-MS), we detected (Z)-6,14-pentadecadienal in volatile collections and in whole body extracts of female A. erythrocephala. Females, but not males, also exhibited a 25-carbon cuticular hydrocarbon, (Z,Z)-1,9,15-pentacosatriene, which can oxidize to (Z)-6,14-pentadecadienal upon exposure to air and sunlight. (Z,Z)-1,9,15-Pentacosatriene and (Z)-6,14-pentadecadienal identifications were corroborated by comparison with synthetic standards. (Z)-6,14-Pentadecadienal is the second pheromone identified for pamphilliid sawflies, and the first to elicit strong field attraction, and thus offer potential as a pheromone lure to aid in control of this forest pest.

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

AB Species limits within the clinically important Fusarium incarnatum-F. equiseti and F. chlamydosporum species complexes (FIESC and FCSC, respectively) were investigated using multilocus DNA sequence data. Maximum-parsimony and maximum-likelihood analyses of aligned DNA sequences from four loci resolved 28 species within the FIESC, within which the species were evenly divided among two clades designated Incarnatum and Equiseti, and four species within the FCSC. Sequence data from a fifth locus, beta-tubulin, was excluded from the study due to the presence of highly divergent paralogs or xenologs. The multilocus haplotype nomenclature adopted in a previous study (K. O'Donnell, D. A. Sutton, A. Fothergill, D. McCarthy, M. G. Rinaldi, M. E. Brandt, N. Zhang, and D. M. Geiser, J. Clin. Microbiol. 46:2477-2490, 2008) was expanded to all of the species within the FIESC and FCSC to provide the first DNA sequence-based typing schemes for these fusaria, thereby facilitating future epidemiological investigations. Multilocus DNA typing identified sixty-two sequence types (STs) among 88 FIESC isolates and 20 STs among 26 FCSC isolates. This result corresponds to indices of discrimination of 0.985 and 0.966, respectively, for the FIESC and FCSC four-locus typing scheme using Simpson's index of discrimination. Lastly, four human and two veterinary isolates, received as members of the FIESC or FCSC, were resolved as five phylogenetically distinct species nested outside these species complexes. To our knowledge, these five species heretofore have not been reported to cause mycotic infections (i.e., F. armeniacum, F. brachygibbosum, F. flocciferum, and two unnamed Fusarium species within the F. tricinctum species complex).

AB Overfeeding prepubertal heifers may impair mammary parenchymal growth and reduce milk production, but evidence suggests that increased intake of a high-protein milk replacer before weaning may be beneficial. This study was designed to evaluate effects of milk replacer (MR) composition on mass and composition of mammary parenchyma and fat pad, growth hormone (GH)/insulin-like growth factor-I (IGF-I) axis gene expression, and putative mammary epithelial stem cells. Specifically, we hypothesized that positive effects of faster rates of gain during the preweaning period alter the development, persistence, or activity of populations of putative mammary epithelial stem cells, possibly through involvement of GH/IGF-I axis molecules. Twenty-four newborn heifers were fed 1 of 4 MR diets (n = 6/diet): control [20% crude protein (CP), 21% fat MR fed at 441 g of dry matter (DM)/d], high protein, low fat (28% CP, 20% fat MR fed at 951 g of DM/d), high protein, high fat (27% CP, 28% fat MR fed at 951 g of DM/d), and high protein, high fat+ (27% CP, 28% fat MR fed at 1,431 g of DM/d). Water and starter (20% CP, 1.43% fat) were offered ad libitum. Animals were killed on d 65 and mammary tissue was subjected to biochemical, molecular, and histological examination. No differences in mammary parenchymal mass or composition, with or without adjusting for empty body weight, were detected. Mass was increased and composition of the mammary fat pad was altered by nutrient intake. No diet differences in putative mammary epithelial stem cell abundance or abundance of transcripts for genes of the GH/IGF-I axis were detected. In this study, growth of the mammary epithelium, size of the mammary epithelial stem cell population, and components of the GH/IGF-I axis did not depend on diet. However, an underlying positive correlation between telomerase, a marker of mammary stem cells, and growth of the mammary parenchyma was detected. Implications of diet-induced effects on mammary fat pad and possible effects on subsequent development and function remain to be determined.

AB The aim of this study was to examine changes in RNA expression for growth factors, cytokines, and receptors in epidermal-dermal tissues of the bovine claw relative to host age, claw segment, and disease state of the horn. Epidermal-dermal tissues were collected from the coronary, wall, sole, and bulb segments of 8- to 9-mo-old Holstein fetuses, normal adult cows, and adult cows with sole ulceration. Anatomic and pathologic characteristics were determined in tissues stained with eosin and hematoxylin, and RNA expression levels were evaluated using real-time, quantitative PCR. In normal tissues, certain RNA expression levels were clearly affected by host age: 290.0-, 610.0-, 53.4-, and 8.1-fold greater expression of granulocyte-macrophage colony stimulating factor was observed in fetal coronary, wall, sole, and bulb segment relative to adult tissues, respectively. A claw segment effect was also observed in that IL-1 alpha expression was greater (1.59-fold) in the normal adult wall relative to the coronary segment, and IL-18 expression was greater (16.2-fold) in the normal adult sole compared with the coronary segment and 2.88 greater in the fetal sole relative to the bulb segment. Sole ulceration was associated with hemorrhage, thrombosis, inflammation, and striking increases in IL-1 beta, IL-18, and inducible nitric oxide synthase, and with less dramatic, albeit measurable, changes in IL-1 type I receptor, IL-1 receptor antagonist, and tumor necrosis factor-alpha. Amidst striking increases in keratinocyte growth factor receptor (i.e., 21.0-fold, 10.4-fold, 0, and 21.6-fold in the coronary, wall, sole, and bulb segments, respectively), a concomitant decrease occurred in keratinocyte growth factor (i.e., 0.80-, 0.54-, 0.56-, and 0.72-fold, respectively). The results demonstrated changes in disease state and, to a lesser extent, claw segment and were accompanied by alterations in the RNA expression of several cytokines, growth factors, and receptors present in the normal claw.

AB Environmental factors, especially temperature and light exposure, influence the health and productivity of dairy cows during lactation, possibly via similar physiological mechanisms. For example, heat stress is a critical component of decreased milk yield during summer. However, less is known about the effect of heat stress during the dry period. The objective of this study was to evaluate the effects of heat stress prepartum under a controlled photoperiod on lactation performance and hepatic metabolic gene expression of periparturient multiparous Holstein cows (n = 16). Cows were dried off approximately 46 d before expected calving date and assigned to treatment randomly after blocking by mature equivalent milk production and parity. Treatments consisted of either heat stress (HT) or cooling (CL) with fans and sprinklers, both under a photoperiod of 14L:10D. Rectal temperature was measured twice daily during the dry period. After calving, cows were housed in a freestall barn with cooling devices, and milk yield was recorded daily up to 210 d in milk. Blood samples were taken from dry off until + 42 d relative to calving for metabolites and from -2 until + 2 d relative to calving for hormone analysis. Daily dry matter intake was measured from -35 to + 42 d relative to calving. Liver biopsies were collected at dry off, -20, + 2, and + 20 d relative to calving for cows on HT (n = 5) and CL (n = 4) to measure mRNA expression of suppressors of cytokine signaling-2 (SOCS-2), insulin-like growth factor binding protein-5 (IGFBP-5), a key transcription factor in lipid biosynthesis (SREBP-1c), and enzymes of lipid metabolism (FASN, ACACA, and ACADVL) by real-time quantitative PCR. Heat stress increased rectal temperatures (39.2 vs. 38.8 degrees C), plasma prolactin concentrations at -1 (171 vs. 79 ng/mL) and 0 d (210 vs. 115 ng/mL) relative to calving, and decreased dry matter intake at 0 and + 14 d relative to calving and 3.5% fat-corrected milk postpartum (26.1 vs. 35.4 kg/d) compared with CL cows. Relative to CL cows, hepatic mRNA expression of SOCS-2 and IGFBP-5 was downregulated in HT cows. Expression of ACADVL was upregulated in CL cows at d + 2 but downregulated at d + 20 relative to HT cows. Concentrations of C16:0 and cis C18:1 were greater in the milk and liver of CL cows compared with HT cows, which reflects greater lipid mobilization. These results suggest that heat-stress abatement in the dry period improves subsequent lactation, possibly via suppression of plasma prolactin surge around calving, SOCS-2 expression, and regulation of hepatic lipid metabolism.

AB The objectives were to quantify and size ambient aerosolized dust in and around the facilities of 4 southern High Plains dairies of New Mexico and to determine where health of workers might be vulnerable to particulate aerosols, based on aerosol concentrations that exceed national air quality standards. Ambient dust air samples were collected upwind (background) and downwind of 3 dairy location sites (loafing pen boundary, commodity, and compost field). The indoor milking parlor, a fourth site, was monitored immediately upwind and downwind. Aerosolized particulate samples were collected using high-volume sequential reference air samplers, laser aerosol monitors, and cyclone air samplers. The overall (main effects and estimable interactions) statistical general linear model statement for particulate matter (PM(10); particulate matter with an aerodynamic diameter of up to 10 mu m) and PM(2.5) resulted in a greater mean concentration of dust in the winter (PM(10) = 97.4 +/- 4.4 mu g/m(3); PM(2.5) = 32.6 +/- 2.6 mu g/m(3)) compared with the summer (PM(10) = 71.9 +/- 5.0 mu g/m(3); PM(2.5) = 18.1 +/- 1.2 mu g/m(3)). The upwind and downwind boundary PM10 concentrations were significantly higher in the winter (upwind = 64.3 +/- 9.5 mu g/m(3); downwind = 119.8 +/- 13.0 mu g/m(3)) compared with the summer (upwind = 35.2 +/- 7.5 mu g/m(3); downwind = 66.8 +/- 11.8 mu g/m(3)). The milking parlor PM(10) and PM(2.5) concentration data were significantly higher in the winter (PM(10) = 119.5 +/- 5.8 mu g/m(3); PM(2.5) = 55.3 +/- 5.8 mu g/m(3)) compared with the summer (PM(10) = 88.6.0 +/- 5.8 mu g/m(3); PM(2.5) = 21.0 +/- 2.1 mu g/m(3)).

AB The physiological response of the preruminant calf to sustained exposure to moderate cold has not been studied extensively. Effects of cold on growth performance and health of preruminant calves as well as functional measures of energy metabolism, fat-soluble vitamin, and immune responsiveness were evaluated in the present study. Calves, 3 to 10 d of age, were assigned randomly to cold (n = 14) or warm (n = 15) indoor environments. Temperatures in the cold environment averaged 4.7 degrees C during the study. Frequent wetting of the environment and the calves was used to augment effects of the cold environment. Temperatures in the warm environment averaged 15.5 degrees C during the study. There was no attempt to increase the humidity in the warm environment. Preventative medications or vaccinations that might influence disease resistance were not administered. Nonmedicated milk replacer (20% crude protein and 20% fat fed at 0.45 kg/d) and a non-medicated starter grain fed ad libitum were fed to all calves. Relative humidity was, on average, almost 10% higher in the cold environment. Warm-environment calves were moderately healthier (i.e., lower respiratory scores) and required less antibiotics. Scour scores, days scouring, and electrolyte costs, however, were unaffected by environmental temperature. Growth rates were comparable in warm and cold environments, although cold-environment calves consumed more starter grain and had lower blood glucose and higher blood nonesterified fatty acid concentrations. The nonesterified fatty acid and glucose values for cold-stressed calves, however, did not differ sufficiently from normal values to categorize these calves as being in a state of negative-energy balance. Levels of fat-soluble vitamin, antibody, tumor necrosis factor-alpha, and haptoglobin were unaffected by sustained exposure to moderate cold. These results support the contention that successful adaptation of the dairy calf to cold is dependent upon the availability of adequate nutrition.

TI An analysis of at-home demand for ice cream in the United States
SO JOURNAL OF DAIRY SCIENCE

DT Article
DE Nielsen home scan retail data; dairy demand; elasticity; ice cream
ID HOUSEHOLD CHEESE PURCHASES; BEHAVIOR
AB Ice cream has been manufactured commercially in the United States since the middle of the 19th century. Ice cream and frozen dessert products comprise an important and relatively stable component of the United States dairy industry. As with many other dairy products, ice cream is differentiated in several dimensions. A censored translog demand system model was employed to analyze purchases of 3 ice cream product categories. The objective of this study was to determine the effect that changes in retail prices and consumer income have on at-home ice cream consumption. The analysis was based on Nielsen 2005 home scan retail data and used marital status, age, race, education, female employment status, and location in the estimations of aggregate demand elasticities. Results revealed that price and consumer income were the main determinants of demand for ice cream products. Calculated own-price elasticities indicated relatively elastic responses by consumers for all categories except for compensated bulk ice cream. All expenditure elasticities were inelastic except for bulk ice cream, and most of the ice cream categories were substitutes. Ongoing efforts to examine consumer demand for these products will assist milk producers, dairy processors and manufacturers, and dairy marketers as they face changing consumer responses to food and diet issues.

AB Western cherry fruit fly, Rhagoletis indifferens Curran (Diptera: Tephritidae), is a major pest of sweet cherry, Prunus avium (L.) L. (Rosales: Rosaceae), that is conventionally controlled using insecticides. One alternative to the use of insecticides alone for fly control could be fumigation of the fly's over-wintering habitat using the fungus Muscodor albus Worapong, Strobel & Hess (Xylariales: Xylariaceae) in conjunction with reduced insecticide use. The fungus produces a mixture of volatile organic compounds (VOCs) that are biocidal for a variety of organisms. In this study, the main objectives were to determine the effects of M. albus VOCs on mortality of R. indifferens pupae and on adult emergence under laboratory conditions. In fumigation chamber experiments, a 14-d exposure of pupae in soil to VOCs resulted in 61.9% control, and exposure to VOCs for 7, 10, and 14 d reduced fly emergence by 44.2, 70.0, and 86.3%, respectively, relative to controls. In an experiment using plastic covers to retain VOCs in treated soil, a concentration of 1% M. albus formulation (fungus + rye grain) did not affect pupal mortality and fly emergence, but a concentration of 5% M. albus formulation resulted in 27.4% control and reduced fly emergence by 30.1% relative to the control. Larvae of R. indifferens that were dropped onto soil with 1% M. albus formulation were not affected by the fungus. Results indicate that prolonged exposure and high concentrations of M. albus VOCs can cause significant mortality of R. indifferens pupae in soil and delay adult emergence.

AB The thermotolerance of the emerald ash borer, Agrilus planipennis Fairmaire (Coleoptera: Buprestidae), was evaluated by subjecting larvae and prepupae to a number of time-temperature regimes. Three independent experiments were conducted during 2006 and 2007 by heating emerald ash borer infested firewood in laboratory ovens. Heat treatments were established based on the internal wood temperature. Treatments ranged from 45 to 65 degrees C for 30 and 60 min, and the ability of larvae to pupate and emerge as adults was used to evaluate the success of each treatment. A fourth experiment was conducted to examine heat treatments on exposed prepupae removed from logs and subjected to ambient temperatures of 50,55, and 60 degrees C for 15,30, 45, and 60 min. Results from the firewood experiments were consistent in the first experiment. Emergence data showed emerald ash borer larvae were capable of surviving a temperatures-time combination up to 60 degrees C for 30 min in wood. The 65 degrees C for 30 min treatment was, however, effective in preventing emerald ash borer emergence on both dates. Conversely, in the second experiment using saturated steam heat, complete mortality was achieved at 50 and 55 degrees C for both 30 and 60 min. Results from the prepupae experiment showed emerald ash borer survivorship in temperature-time combinations up to 55 degrees C for 30 min, and at 50 degrees C for 60 min; 60 degrees C for 15 min and longer was effective in preventing pupation in exposed prepupae. Overall results suggest that emerald ash borer survival is variable depending on beating conditions, and an internal wood temperature of 60 degrees C for 60 min should be considered the minimum for safe treatment for firewood.

AB With the recent decline of honey bees, Apis mellifera (L.) (Hymenoptera: Apidae), there is a need for alternative or supplemental crop pollinators, such as Osmia cornifrons (Radoszkowski) (Hymenoptera: Megachilidae). However, O. cornifrons propagation could be impeded by a cleptoparasitic mite, Chaetodactylus krombeini Baker. We investigated the effects of formic acid and wintergreen oil on mortality of C. krombeini hypopi and O. cornifrons adults by determining the lethal concentration of each compound on each species. On average, >4.8 and >1.8 h were required to cause mortality in O. cornifrons adults when <2,473.5 ppm of formic acid and wintergreen oil was applied as a fumigant, respectively. When the two chemicals were directly applied to the exoskeleton of O. cornifrons adults, 353.4 ppm of wintergreen oil caused bee mortality within 10 min; however, no mortality was found with any formic acid application attempted. Mortality of C. krombeini hypopi occurred 5 and 10 min after application of > 176.7 ppm of formic acid and wintergreen oil, respectively. Estimates of LC(50) for C. krombeini hypopi treated with formic acid and wintergreen oil were 54.3 and 271.3 ppm, respectively. This study showed that C. krombeini could be controlled effectively without inducing O. cornifrons adult mortality based on concentration and duration of fumigation.

AB Retinal sensitivity of Agrilus planipennis Fairmaire (Coleoptera: Buprestidae) was examined with an aim to improve trap efficacy for the beetle. Electroretinogram (ERG) recordings from dark-adapted compound eyes of male and female were measured at different wavelengths across the spectrum ranging from 300 to 700 nm. The spectral sensitivity curves revealed peaks in the UV (340 nm), the violet/purple (420-430 nm), blue (460 nm), and green (540-560 nm) regions of the spectrum. Females were sensitive to red regions of the spectrum (640-670 nm), whereas males were not. A spectrophotometer was used to measure the wavelength and reflectance for ash foliage, purple corrugated plastic traps, as well as the elytra and abdomen of adult A. planipennis. Traps were painted using colors based on ERG and spectrophotometer measurements and compared with purple corrugated plastic traps currently used by the USDA-APHIS-PPQ-EAB National Survey. In a field assay conducted along the edges of several A. planipennis-infested ash stands, there were no significant differences in trap catch among green, red, or purple treatments. Dark blue traps caught significantly fewer A. planipennis than red, light green, or dark purple traps. In a second assay where purple and green treatments were placed in the mid canopy of ash trees (approximate to 13 m in height), trap catch was significantly higher on green treatments. We hypothesize that when placed in the mid-canopy, green traps constitute a foliage-type stimulus that elicits food-seeking and/or host seeking behavior by A. planipennis.

AB The western pine beetle, Dendroctonus brevicomis LeConte (Coleoptera: Curculionidae: Scolytinae), is a major cause of ponderosa pine, Pinus ponderosa Dougl. ex Laws., mortality in much of western North America. This study was designed to quantify relationships between western pine beetle trap catches [including those of its primary invertebrate predator Temnochila chlorodia (Mannerheim) (Coleoptera: Trogositidae)], and levels of tree mortality attributed to western pine beetle at 44 trapping sites (stands) and within five general locations (forests) in California. Furthermore, we evaluated relationships between forest stand characteristics and levels of western pine beetle-caused tree mortality. Preliminary analyses were conducted by Pearson's correlation coefficient (r) using tree mortality per hectare and percentage of tree mortality and 10 potential predictor variables. All predictor variables that had significant correlations (western pine beetle per day, western pine beetle: T. chlorodia, percentage of western pine beetle [percentage of total trap catch represented by western pine beetle], trees per hectare, basal area of all tree species, basal area of P. ponderosa, mean diameter at breast height [dbh] and stand density index) were considered for linear and multiple linear regression models for predicting levels of western pine beetle-caused tree mortality. Our results suggest monitoring western pine beetle populations through the use of pheromone-baited multiple funnel traps is not air effective means of predicting levels of western pine beetle-caused tree mortality. However, levels of western pine beetle-caused tree mortality can be efficiently predicted (adjusted R(2)>0.90) at large spatial scales (forests; approximate to 3,000-14,000 ha of contiguous host) by simply measuring stand density, specifically the basal area of all tree species or stand density index. The implications of these results to forest management are discussed.

AB The purpose of this stud), was to develop and evaluate lures for adult green June beetles, Cotinis nitida (L.) (Coleoptera: Scarabaeidae), for future use in a mass trapping program. Volatile organic compounds collected from headspace of green June beetles feeding on fermenting ripe apple (Malus spp.), the natural lure that elicits feeding aggregations, were identified and confirmed by gas chromatography and mass spectrometry. Yellow funnel traps baited with 91% isopropanol. or the five component blend were equally effective in eliciting aggregation behavior and often more attractive to green June beetles than the natural lure. In 2008, three trap lines adjacent and parallel to the perimeter of two vineyards, each with 12 Xpando yellow funnel traps baited with either 91% isopropanol or the five component blend, differed in catch of green June beetles across sample dates, and sample date by bait interaction but there were no differences among these two baits. A season total of 324,007 green June beetle were captured by these 36 baited traps. A brief review is included of fermentation volatiles attractive to insects.

AB Bifenthrin, chlorfenapyr, fipronil, and thiamethoxam were evaluated for activity against the Argentine ant, Linepitheyma humile (Mayr) (Hymenoptera: Formicidae). Mobility impairment and lethal times were determined after topical treatments. Ants were immobilized most quickly by bifenthrin, followed by chlorfenapyr and thiamethoxam. After 2 h, the number of fipronil-treated ants unable to walk out of test arenas did not differ from control ants. Median lethal time (LT,,) after topical treatment was lowest in the bifenthrin treatment, followed by thiamethoxam, chlorfenapyr, and then fipronil. Mortality due to horizontal exposure was evaluated at 10, 20, or 30 degrees C, with topically treated ant corpses serving as donors. There was low to moderate horizontal activity in bifenthrin and chlorfenapyr treatments, with no temperature effect in bifenthrin treatments and a positive temperature effect in chlorfenapyr treatments. Mortality in the fipronil treatments was highest and was positively correlated with temperature. Thiamethoxam treatments did not differ from controls at 10 degrees C, but mortality increased with temperature. To evaluate contact activity, either all of 20% of the ants in a cohort were exposed to insecticide-treated pine needles. In both tests, mortality was highest in fipronil and bifenthrin treatments, followed by thiamethoxam, with lowest mortality in chlorfenapyr treatments. Effectiveness as a barrier was evaluated by providing a choice between bridges treated with insecticide or water. Although bifenthrin did not provide an impenetrable barrier, it was the only treatment having fewer ants than its paired control. Mortality data suggest that lack of recruitment rather than repellency account for this result.

AB The genetic diversity of Tamarixia radiata Waterston (Hymenoptera: Eulophidae) laboratory colonies derived from collections in China, northern Vietnam, Pakistan, and a mixed colony from Taiwan and southern Vietnam was evaluated using the internal transcribed spacer (ITS) region 1, ITS-2, and the 5' end of the cytochrome oxidase subunit I gene. The strains share the same ITS sequence, consistent with the morphological hypothesis that the collections represent a single species. The COI marker was variable and could distinguish the northern Vietnam and Pakistan colonies from each other and from the other colonies. Comparison of COI sequences from field-collected populations of Puerto Rico, Guadeloupe, and Texas indicates that Florida is not a likely source of the introduction into Puerto Rico but is a likely source of the introduction into Texas.

This protocol distinguishes the light brown apple moth from other moths in California based on size differences of PCR amplicons that are visualized on agarose gels. The molecular diagnostic too] generated no false negatives based on analysis of 337 light brown apple moths collected from California, Hawaii, England, New Zealand, and Australia. Analysis of a data set including 424 moths representing other tortricid species generated correct identification for >95% of the samples and only two false positives. Of the 761 moths tested only fourteen produced no PCR amplicons and five generated inconclusive data.

AB Seven maize, Zea mays L., genotypes selected for native resistance to western corn rootworm, Diabrotica virgifera virgifera LeConte (Coleoptera: Chrysomelidae), larval feeding damage (SUM2068, SUM2162, CRW3(S1)C6, NSS1XCRW3(S1)C6, PI583927, CRW2(C5), and AR17056-16) were evaluated along with three control maize genotypes in the field for plant damage, larval recovery, adult emergence, root size, and root regrowth. Larvae recovered were further analyzed for head capsule width and dry weight and adults for dry weight. All factors evaluated with the. exception of adult dry weight varied significantly among maize genotypes. Control genotypes included a highly susceptible hybrid, B37XH84, a transgenic rootworm-resistant hybrid expressing the modified Cry3A protein (MIR604), and the untransformed modern hybrid with the same genetic background as the MER604 we used (isoline) as a second susceptible control. In general, the genotypes previously selected for resistance to western corn rootworm larval feeding had less damage, fewer larvae recovered, smaller larvae recovered, and fewer adults recovered that the susceptible controls. SUM2162 was significantly less damaged than all other native sources of resistance. Western corn rootworm larvae recovered from SUM2162 and SUM2068 were significantly smaller in terms of head capsule width and average weight than larvae recovered from all other maize genotypes, indicating that antibiosis is a mechanism of resistance for these two hybrids.

AB Several species of Anastrepha and Bactrocera fruit flies (Diptera: Tephritidae) are captured in traps baited with the protein bait NuLure combined with borax (sodium tetraborate decahydrate) in an aqueous solution, typically 9% NuLure (vol:vol) with 3% borax (wt:vol). NuLure is an acid hydrolysate of corn and has an acidic pH. Addition of borax makes the solution more alkaline, and increase in alkalinity results in increase of ammonia release from the bait solution. This is a very dynamic system, with resultant pH affected by factors such as the amount of borax added, the pH of the water used for preparation, the age of the bait solution, and the development of microbial growth. Problems with borax include amount needed to increase alkalinity of NuLure solutions, which creates difficulties in disposing of spent bait in fruit fly trapping programs. Therefore, research was conducted to evaluate NaOH as an alternative method to increase alkalinity of NuLure solutions. Laboratory experiments compared effect of NaOH versus borax for pH modification on changes in pH and ammonia content of NuLure solutions over time. Although NuLure/NaOH solutions could be adjusted to a more alkaline pH than NuLure/borax solutions, borax plays a critical role in pH stability over time. However, the pH of NuLure/NaOH is stabilized when propylene glycol (10% vol:vol) was used to prepare the bait solution. The use of NaOH can provide an alternative to the use of borax to increase bait solution alkalinity.

ID UNSATURATED FLOW; TEST HOLE; PERMEAMETER
AB The objectives of the study discussed in this article were to develop an empirical relationship between the saturated hydraulic conductivity (Ks) of layered soils and their percolation times (PT) in order to understand the influence of individual layers and compare this with the equations developed by Winneberger (1974) and Fritton, Ratvasky, and Petersen (1986). Field research was conducted on three silt loam soils. Six holes were spaced evenly in two parallel rows of three holes. The Ks was measured at three different layers for each soil using a constant head well permeameter. After completion of the second Ks measurement, the percolation test was conducted. Three linear equations for the upper, middle, and lower layers were developed between the Ks values of each individual layer in all three sites and the corresponding PT. Significant differences were found between the author's results and those predicted by Winneberger (1974) and Fritton and co-authors (1986).

AB The two-fold purpose of this paper is to examine the adequacy of food composition databases and dietary assessment techniques to meet the needs of nutritional genomic research and to explore the challenges and opportunities presented by the emerging field of nutrigenomics to future development of food composition databases and food composition analysis systems. A review Of published literature and the Internet for organizations and their ongoing dialogues were used to explore how current food composition databases and nutritional assessment methodology could be made more useful in nutrigenomics research. An outline of current projects and potential approaches to develop more reliable and cost-effective methods for the study of nutrigenomics in diverse populations is presented. Many issues related to these dietary and database methodologies need to be addressed and overcome if nutrigenomics is to reach its potential for promoting optimal health through better individualization of diet and physical activity recommendations. To meet the complex research and clinical challenges of individualizing nutrition and health care, a network of diverse health care professionals and scientists is needed to move the world toward optimal health practices.

AB Dietary N-nitroso compounds are carcinogens synthesized during food processing from two main classes of precursors, oxides of nitrogen and amines or amides. Quantification of the dietary intake of N-nitroso compounds is significant to human cancers, including those of the stomach and upper gastro-intestinal tract, colon, and brain. Previous studies investigating these cancers primarily used proxy estimates of N-nitroso intake and not a full and complete database. In this report, we describe the development of a database to be used in conjunction with a food frequency questionnaire (FFQ) or 24 h dietary records. Published analytical data for N-nitroso compounds were compiled and evaluated for inclusion in the database. The final database consisted of 23 different N-nitroso compounds for 500 foods from 39 different food subgroups. Next, database foods were matched to foods in a standard FFQ by imputation, or calculated value, or assumed zero. Using the FFQ modified with N-nitroso values, we evaluated the ability to compute N-nitroso intakes for a sample of healthy control subjects of cancer epidemiological studies. N-nitroso content of food items ranged from <0.01 mu g/100 g to 142 mu g/100 g and the richest sources were sausage, smoked meats, bacon, and luncheon meats. The database is useful to quantify N-nitroso intake for observational and epidemiological studies. (C) 2009 Elsevier Inc. All rights reserved.

ID SYSTEM
AB The National Cancer Institute (NCI) is developing an automated, self-administered 24-hour dietary recall (ASA24) application to collect and code dietary intake data. The goal of the ASA24 development is to create a web-based dietary interview based on the US Department of Agriculture (USDA) Automated Multiple Pass Method (AMPM) instrument currently used in the National Health and Nutrition Examination Survey (NHANES). The ASA24 food list, detail probes, and portion probes were drawn from the AMPM instrument; portion-size pictures from Baylor College of Medicine's Food Intake Recording Software System (FIRSSt) were added; and the food code/portion code assignments were linked to the USDA Food and Nutrient Database for Dietary Studies (FNDDS). The requirements that the interview be self-administered and fully auto-coded presented several challenges as the AMPM probes and responses were linked with the FNDDS food codes and portion pictures. This linking was accomplished through a "food pathway," or the sequence of steps that leads from a respondent's initial food selection, through the AMPM probes and portion pictures, to the point at which a food code and gram weight portion size are assigned. The ASA24 interview database that accomplishes this contains more than 1100 food probes and more than 2 million food pathways and will include about 10,000 pictures of individual foods depicting up to 8 portion sizes per food. The ASA24 will make the administration of multiple days of recalls in large-scale studies economical and feasible. (C) 2009 Elsevier Inc. All rights reserved.

AB Whole cantaloupes either not inoculated or inoculated with Salmonella Poona were submerged in water, 180 ppm of chlorine, acidified calcium sulfate (ACS: 1.2% Safe(2)O-ACS50), 1,000 ppm of acidified sodium chlorite (ASC), 80 ppm of peroxyacetic acid (PAA), and a combination of ACS and PAA for 10 min. Although only ASC and the combination of ACS and PAA significantly reduced the aerobic plate count of samples taken from the surface of whole cantaloupe (compared with samples taken from cantaloupe submerged in water only), all treatments reduced yeast and mold counts on the whole cantaloupe. However, none of the treatments of whole cantaloupes consistently reduced yeast and mold counts for the samples of fresh-cut cantaloupes. The aerobic plate counts for fresh-cut cantaloupe were reduced by I to 2 log CFU/g by sanitization of whole fruit with ASC, ACS, and the combination of ACS and PAX The low bacterial population oil the fresh-cut fruit was maintained during 14 days of storage at 4 degrees C. All treatments had a limited effect on the population of Salmonella, achieving no more than a 1.5-log reduction of the pathogen inoculated on the surface of the whole cantaloupes. Salmonella was nondetectable via direct plating (with a detection limit of 0.4 log CFU/g) in fresh-cut cantaloupes prepared from whole cantaloupes treated with any of the sanitizers. However, after enrichment, Salmonella often was detectable. Color, texture, soluble solids, pH, ascorbic acid, and drip loss of cut cantaloupes were not consistently affected by any of the whole-fruit treatments. Overall, treatments of whole cantaloupe with ASC, ACS, and the combination of ACS and PAA at the concentrations tested permitted a significant reduction in Salmonella and native microflora of whole and cut fruit; however, Salmonella still could be found in cut cantaloupes from all treatments.

TI Effect of Storage and Subsequent Reheating on Viability of Listeria

ID 4-DEGREES-C; SURFACE; LACTATE; STRAIN
AB We evaluated the fate of Listeria monocytogenes on commercial pork scrapple, a regionally popular, ready-to-eat (RTE) meat. We also conducted an informal survey to address consumer practices for storing and reheating scrapple. Of the 129 consumers who responded to at least one of the eight questions posed in the survey, about half (46.4%; 52 of 112) considered scrapple RTE, the majority (69.7%; 76 of 109) stored it in the refrigerator, and all (100%; 112 of 112) preferred to reheat it prior to consumption. Most respondents (83.9%; 94 of 112) reheated the scrapple by pan frying for I to 10 min at medium to high temperature. To study pathogen behavior, slices of pork scrapple were surface inoculated with a five-strain cocktail of L. monocytogenes (ca. 2.0 log CFU/g), vacuum sealed, and stored for up to 60 days. Pathogen levels increased to 8.9, 9.5, and 9.9 log CFU/g after 44 (4 degrees C), 21 (10 degrees C), and 5 (21 degrees C) days, respectively. When slices 1.3 cm (ca. 55 g) and 1.9 cm (ca. 85 g) thick were surface inoculated with L. monocytogenes (ca. 7.0 log CFU/g) and then reheated in a skillet (191 degrees C) for 0.5 to 4 min per side or to target instantaneous internal temperatures of 48.9 to 71.1 degrees C, it was possible to achieve pathogen reductions ranging from ca. 2.2 to 6.5 log CFU/g. These data confirm that in the unlikely event of postprocessing contamination of pork scrapple by L. monocytogenes, proper reheating can appreciably reduce levels of the pathogen before consumption.

AB North American genotypes of Trichinella spiralis (T-1), Trichinella nativa (T-2), Trichinella pseudospiralis (T-4), Trichinella murrelli (T-5), and Trichinella T-6 were examined for susceptibility to freezing in pork using time-temperature combinations that have been proven to inactivate T. spiralis. Infections were established in 3-month-old pigs of mixed sex and breed by oral inoculation of 10,000 muscle larvae (ML) (all genotypes, rodent-derived ML), 20,000 ML (T-1, TA and T-5; cat-derived ML), or 30,000 ML (T-2 and T-6; cat-derived ML). Pigs were euthanized 60 days postinoculation. Muscles from the tongue, masseter muscles, diaphragm, triceps, hams, neck, rump, and loins were ground, pooled, and mixed to ensure even distribution of larvae. Samples (20 g) containing each Trichinella species, genotype, and source combination were placed in heat-scalable pouches, transferred to a constant temperature refrigerant bath, and maintained according to defined time and temperature combinations. Larvae recovered from cold-treated pork samples were inoculated into mice to determine infectivity. Results indicated that the time-temperature combinations known to render pork safe for T. spiralis are sufficient to inactivate T. nativa and T-6 (the freeze-resistant isolates), T. murrelli (the most common sylvatic species in the United States excluding Alaska), and T. pseudospiralis (a species that lacks a muscle nurse cell). These data close a gap in knowledge about the effectiveness of freezing for inactivating these parasites in pork and should alleviate concern about the safety of frozen pork products from the United States.

AB Ractopamine HCl and zilpaterol HCl, beta-agonists recently approved for use in feedlot cattle to improve performance traits and carcass leanness, were examined for their effects on fecal shedding of Escherichia coli O157:H7 in feedlot cattle. Fecal samples (n = 2,454) were obtained from four experiments (one ractopamine HCl, three zilpaterol HCl) over the course of a 3-year period, either by rectal palpation (ractopamine HCl experiment) or from pen-floor fecal pats. Samples were cultured quantitatively and qualitatively for E. coli O157:H7. No significant treatment differences were detected for fecal prevalence of E. coli O157:H7 in the ractopamine HCl experiment. Zilpaterol HCl feeding had no effect (P > 0.20) on fecal shedding in the first or second experiments, with overall E. coli O157:H7 prevalence relatively low (<7%). In the third zilpaterol HCl experiment, the percentage of fecal samples that were E. coli O157:H7 positive following qualitative culture was higher (P < 0.05) in the zilpaterol HCl treatment (10.3%) than for the control (6.1%). The current research showed minimal effects of beta-agonists on fecal shedding of E. coli O157:H7 and indicated that these compounds (fed immediately prior to slaughter) are not a cause for concern from a food safety standpoint.

AB Listeriosis is a severe infection with high morbidity and mortality. We report a fatal case of listeriosis in a patient with a history of Crohn's disease who consumed chicken salad purchased from a retail food establishment before developing listeriosis. As part of the regulatory testing programs, the U.S. Department of Agriculture Food Safety and Inspection Service and the Florida Department of Agriculture and Consumer Affairs found that chicken products from a single food-production establishment were contaminated with Listeria monocytogenes, resulting in a product recall. The case patient's Listeria isolate was subtyped by pulsed-field gel electrophoresis (PFGE) and matched the Listeria isolates from the recalled chicken products. Identification of the source of Listeria involved collaboration among two state public health laboratories and epidemiologists and state and federal regulatory agencies. PFGE typing can be used to reveal correlations between clusters of human illness and contaminated food products and to rapidly identify sources of Listeria infection to allow implementation of corrective actions at both the state and national levels.

AB Fire is a dominant disturbance within many forested ecosystems worldwide. Understanding the complex feedbacks among vegetation as a fuel for fire, the effects of fuels on fire behavior, and the impact of fire behavior on future vegetation are critical for sustaining biodiversity, in fire-dependent forests. Nonetheless, understanding in fire ecology has been limited in part by the difficulties in establishing the connections between fire behavior and vegetation response. To address this issue, we present the concept of the ecology of fuels, which emphasizes the critical role that fuels play in conceptually linking feedbacks between fire and vegetation. This article explores the ecology of the fuels concept for longleaf pine woodlands and illustrates its utility by evaluating the principles of ecological forestry (incorporating legacies of disturbances, understanding intermediate stand development processes, and allowing for recovery periods) in this chronically disturbed ecosystem. We review the research behind our understanding of these feedbacks in longleaf pine ecosystems of the southeastern United States and review the applications of these principles through the Stoddard-Neel method of ecological forestry. Understanding these feedbacks is critical for integrating fire ecology and ecological forestry in the Southeast and in other fire-dependent forest types.

ID BOUNDARY OVERLAP
AB Mapped plots are used for the national forest inventory conducted by the US Forest Service. Mapped plots are also useful for single ownership inventories. Mapped plots can handle boundary overlap and can provide less variable estimates for specified forest conditions. Mapping is a good fit for fixed plot inventories where the fixed area plot is used for both mapping and tree sampling. However, mapping can he done with a colocated fixed area plot even though the tree inventory uses variable plots. In fact, the tree measurement plots can be completely decoupled from the plots used for measuring condition proportions, although this is not recommended.

FIELD APPLICATION; WATER CONTENT; MODEL; FRAMEWORK; IMPACT; FLUXES
AB Root-zone soil moisture controls the land-atmosphere exchange of water and energy, and exhibits memory that may be useful for climate prediction at monthly scales. Assimilation of satellite-based surface soil moisture observations into a land surface model is an effective way to estimate large-scale root-zone soil moisture. The propagation of surface information into deeper soil layers depends on the model-specific representation of subsurface physics that is used in the assimilation system. In a suite of experiments. synthetic surface soil moisture observations are assimilated into four different models [Catchment, Mosaic, Noah, and Community Land Model (CLM)] using the ensemble Kalman filter. The authors demonstrate that identical twin experiments significantly overestimate the information that can be obtained from the assimilation of surface soil moisture observations. The second key result indicates that the potential of surface soil moisture assimilation to improve root-zone information is higher when the surface-root zone coupling is stronger. The experiments also suggest that (faced with unknown true subsurface physics) overestimating surface-root zone coupling in the assimilation system provides more robust skill improvements in the root zone compared with underestimating the coupling. When CLM is excluded from the analysis, the skill improvements from using models with different vertical coupling strengths are comparable for different subsurface truths. Last, the skill improvements through assimilation were found to be sensitive to the regional climate and soil types.

TI Corrosion Rates of Fasteners in Treated Wood Exposed to 100% Relative
Humidity
SO JOURNAL OF MATERIALS IN CIVIL ENGINEERING
LA English
DT Article
AB In the past, gravimetric corrosion data for fasteners exposed to treated wood has been reported as a percent weight loss. Although percent weight loss is a valid measure of corrosion for comparing identical fasteners, it can distort the corrosion performance of fasteners with different geometries and densities. This report reevaluates a key report on the corrosiveness of wood treated with chromated copper arsenate (CCA) and ammoniacal copper arsenate (ACA) and converts the previous data into corrosion rates. In addition, similar experiments were run in wood treated with alkaline copper quaternary (ACQ). Comparison of the corrosion rates reveals ACQ treated wood is more corrosive than CCA treated wood for every metal. The corrosion rate of aluminum was found to be lower than both hot-dip galvanized steel and electroplated galvanized steel in ACQ, ACA, and CCA treated wood. In ACA and ACQ treated wood, the electroplated galvanized fastener had a lower corrosion rate than the hot-dip galvanized fastener.

AB Ageing is associated with a decline in immune function, which predisposes the elderly to a higher incidence of infections. Information on the mechanism of the age-related increase in susceptibility to Salmonella enterica serovar Typhimurium (S. Typhimurium) is limited. In particular, little is known regarding the involvement of the immune response in this age-related change. We employed streptomycin (Sm)-pretreated C57BL/6 mice to develop a mouse model that would demonstrate age-related differences in susceptibility and immune response to S. Typhimurium. In this model, old mice inoculated orally with doses of 3 x 10(8) or 1 x 10(6) c.f.u. S. Typhimurium had significantly greater S. Typhimurium colonization in the ileum, colon, Peyer's patches, spleen and liver than young mice. Old mice had significantly higher weight loss than young mice on days 1 and 2 post-infection. In response to S. Typhimurium infection, old mice failed to increase ex vivo production of IFN-gamma and TNF-alpha in the spleen and mesenteric lymph node cells to the same degree as observed in young mice; this was associated with their inability to maintain the presence of neutrophils and macrophages at a 'youthful' level. These results indicate that Sm-pretreated C57BL/6 old mice are more susceptible to S. Typhimurium infection than young mice, which might be due to impaired IFN-gamma and TNF-alpha production as well as a corresponding change in the number of neutrophils and macrophages in response to S. Typhimurium infection compared to young mice.

AB To explore their bioactive fractions, Sageretia theezans leaves were extracted with 60% acetone and then fractionated sequentially with hexane, ethyl acetate, and water. Reactive oxygen radical species (ROS) (HOCl, ONOO(-), and O(2)(center dot-)) scavenging activity, oxygen radical absorbance capacity (ORAC) value, and total phenolic content of each fraction were investigated. The ethyl acetate fraction had the largest total phenolic content and ORAC value and displayed the strongest ROS scavenging activity. The ethyl acetate fraction at 2 mu mol of gallic acid equivalents/L prolonged the lag time of low-density lipoprotein oxidation by 260% compared to the control. In the ethyl acetate fraction, 7-O-methylmearnsetin 3-O-rhamnoside and the other nine flavonols were characterized using high-performance liquid chromatography with electrochemical detection. The total flavonoid content in the ethyl acetate fraction was 460 mg/g. 7-O-Methylmyricetin 3-O-rhamnoside and 7-O-methylmearnsetin 3-O-rhamnoside were the predominant flavonoids, making up 36% and 17% of the total flavonoid content, respectively.

AB Nine new tetranorditerpenoid dilactones (2-10), together with two previously reported norditerpenoids dilactones (1, 11), and two known putative biosynthetic intermediates, oidiolactone-E (12) and 13, were isolated from an ethyl acetate extract of a culture medium of Sclerotinia homoeocarpa. Structures and absolute configurations of these compounds were determined by spectroscopic methods and confirmed by X-ray crystallographic analysis of representative compounds. Compounds were evaluated for herbicidal, antiplasmodial, and cytotoxic activities. Compounds 1, 2, 6, 7, and 11 were more active as growth inhibitors in a duckweed bioassay (I-50 values of 0.39-0.95 mu M) than more than half of 26 commercial herbicides previously evaluated using the same bioassay. Some of these compounds exhibited strong antiplasmodial activities as well, but they also had cytotoxic activity, thus precluding them as potential antimalarial agents.

AB The antibiotic 2,4-diacetylphloroglucinol (DAPG) is produced by some isolates of the beneficial bacterium Pseudomonas fluorescens. DAPG is toxic to many organisms, anti crop yield increases have been reported after application of DAPG-producing P fluorescens. This study was conducted to determine whether DAPG is toxic to selected nematodes. The plant-parasitic nematodes Heterodera glycines, Meloidogyne incognita, Pratylenchus scribneri and Xiphinema americanum, and the bacterial-feeding nematodes Caenorhabditis elegans, Pristionchus pacificus, and Rhabditis rainai, were immersed in concentrations ranging from 0 to 100 mu g/ml DAPG. Egg hatch and viability of juveniles and adults were determined. DAPG was toxic to X. americanum adults, with an LD(50) of 8.3 mu g/ml DAPG. DAPG decreased M. incognita egg hatch, but stimulated C. elegans hatch during the first hours of incubation. Viability of M. incognita J2 and of C. elegans 11 and adults was not affected. There were no observed effects on the other nematodes. The study indicated that DAPG is not toxic to all nematodes, and did not affect the tested species of beneficial bacterial-feeding nematodes. Augmentation of DAPG-producing P. fluorescens populations for nematode biocontrol could be targeted to specific nematode species known to be affected by this compound and by other antibiotics produced by the bacteria, or these bacteria could be used for other possible effects, such as induced plant resistance.

AB The endospore-forming bacterium Pasteuria penetrans is an obligate parasite of root-knot nematodes (Meloidogyne spp.). The primary objective of this study was to determine the effect of crop sequence on abut dance of P penetrans. The experiment was conducted from 2000 to 2008 at a field site naturally infested with both the bacterium and its host Meloidogyne (miliaria and included the following crop sequences: continuous peanut (Arachis hypogaea) (P-P-P) and peanut rotated with either 2 years of corn (Zen mays) (C-C-P), 1 year each of cotton (Gossypium hirsutum) and corn (Ct-C-P), or 1 year each of corn mid a vegetable (V-C-P). The vegetable was a double crop of sweet corn and eggplant (Solanum melongena). A bioassay with second-stage juveniles 92) of M. arenaria from a greenhouse (GH) population was used to estimate endospore abundance under the different. crop sequences. A greater numerical increase in endospore densities was expected in the P-P-P and V-C,P sequences than in the other sequences because both peanut and eggplant are good hosts for M. area aria. However, endospore densities, as determined by bioassay, did not substantially increase in any of the sequences during the 9-year experiment. To determine whether the nematode population had developed resistance to the resident P penetrans, five single egg-mass (SEM) lines from the field population of M. arenaria were tested alongside the CH population for acquisition of endospores from the field soil. Four of the five SEM lines acquired 9 to 14 spores/J2 whereas the CH population and one of the SEM lines acquired 3.5 and 1.8 spores/J2, respectively. Endospore densities estimated with the four receptive SEM lines were highest in the P-P-P plots (14-20 spores/J2), intermediate in the V-C-P plots (6-7 spores/J2), and lowest in the Ct-C-P plots (<1 spore/J2). These results indicate that the field population of M. arenaria is heterogeneous for attachment of P penetrans endospores. Moreover, spore densities increased under intensive cropping of hosts for M. arenaria, but the GH population of the nematode was not receptive to spore attachment. However, previously, the GH population was very receptive to spore acquisition From this field site. One explanation for this inconsistency is that. the NI. arenaria population in the field became resistant to the dominant subpopulation of P penetrans that had been present, and this led to the selection of a different subpopulation of the bacterium that is incompatible with the GH population.

AB APOA5-1131T > C and S19W single nucleotide polymorphisms (SNP) have been consistently associated with plasma lipid concentration and metabolic syndrome (MetS), alone and in modulation by dietary factors. Puerto Ricans have a high prevalence of metabolic conditions and high minor allele frequency for these SNP, suggesting a possible role in disease for this population. We aimed to determine the association of APOA5-1131T > C and S19W with plasma lipids and markers of MetS, alone and in interaction with total fat intake, as a percent of total energy intake, in Puerto Ricans. Anthropometric and demographic data, FFQ, and blood samples were collected at baseline from participants in the Boston Puerto Rican Health Study (n = 802, 45-75 y). APOA5 S19W was associated with plasma HDL cholesterol (HDL-C) (P = 0.044); minor allele carriers had lower HDL-C [1.12 +/- 0.03 (mean +/- SE)] than those with the common variant (1.18 +/- 0.01 mmol/L), even after adjustment for plasma triglycerides (TG) (P = 0.012). Neither polymorphism was associated with TG or other lipids. Interaction of the -1131T > C SNP with total fat energy intake was observed for plasma TG (P = 0.032) and total cholesterol (P = 0.034). APOA5 S19W interacted with total fat intake in association with systolic (P = 0.002) and diastolic (P = 0.007) blood pressure. Neither SNP was associated with MetS in the overall analysis or after stratifying by total energy intake as fat. In conclusion, Puerto Ricans present a distinctive lipid profile in association with APOA5 polymorphisms. Dietary fat intake seems to modulate these associations. The results contribute to the understanding of health disparities in this population. J. Nutr. 139: 2301-2308, 2009.

AB High intake of fish and (n-3) PUFA may protect against age-related cognitive decline. However, results are inconsistent and limited data exist regarding changes in multiple cognitive functions over a longer period of time. In this study, we assessed the association between fatty fish intake as well as (n-3) PUFA intake with cognitive performance and cognitive change over 6 y in 1025 elderly men. Participants were from the Veterans Affairs Normative Aging Study. Cognitive function was assessed with a battery of cognitive tests focusing on factors representing memory/language, speed, and visuospatial/attention, Dietary intakes were assessed with a validated FFQ. We used general linear models to assess cross-sectional associations and mixed models to assess the associations over time. Models were adjusted for age, education, BMI, smoking, diabetes, and intake of alcohol, saturated fat, vitamin C, and vitamin E. The mean age of participating men was 68 y at baseline. Median fish consumption ranged from 0.2 to 4.2 servings/wk across quartiles. Cross-sectional analyses showed no association between fatty fish or (n-3) PUFA intake and cognitive performance. Longitudinal analyses, over 6 y of follow-up, also did not show any significant associations between fatty fish or (n-3) PUFA intake and cognitive change. In this population of elderly men, intake of neither fatty fish nor (n-3) PUFA was associated with cognitive performance. J. Nutr. 139: 2329-2336, 2009.

AB Experimental studies demonstrated that maternal exposure to certain environmental and dietary factors during early embryonic development can influence the phenotype of offspring as well as the risk of disease development at the later life. DNA methylation, an epigenetic phenomenon, has been suggested as a mechanism by which maternal nutrients affect the phenotype of their offspring in both honeybee and agouti mouse models. Phenotypic changes through DNA methylation can be linked to folate metabolism by the knowledge that folate, a coenzyme of one-carbon metabolism, is directly involved in methyl group transfer for DNA methylation. During the fetal period, organ-specific DNA methylation patterns are established through epigenetic reprogramming. However, established DNA methylation patterns are not immutable and can be modified during our lifetime by the environment. Aberrant changes in DNA methylation with diet may lead to the development of age-associated diseases including cancer. It is also known that the aging process by itself is accompanied by alternations in DNA methylation. Diminished activity of DNA methyltransferases (Dnmts) can be a potential mechanism for the decreased genomic DNA methylation during aging, along with reduced folate intake and altered folate metabolism. Progressive hypermethylation in promoter regions of certain genes is observed throughout aging, and repression of tumor suppressors induced by this epigenetic mechanism appears to be associated with cancer development. In this review, we address the effect of folate on early development and aging through an epigenetic mechanism, DNA methylation. (C) 2009 Elsevier Inc. All rights reserved.

AB The synlophe, or system of longitudinal cuticular ridges characteristic of some trichostrongyloid nematodes, is examined in detail for 6 of 8 species in Longistrongylus (Ostertagiinae) that occur in ungulates across sub-Saharan Africa. Among the species of Longistrongylus examined, 5 are characterized by a tapering pattern laterally in the cervical zone (anterior to the esophageal-intestinal junction), which is largely consistent among multiple male and female specimens; in contrast, for Longistrongylus meyeri the lateral pattern is parallel. The synlophe is bilaterally symmetrical, with ridges extending from the base of the cephalic expansion to near the caudal extremity in males and females. Ridges are acutely pointed, with perpendicular orientation and absence of gradient as viewed in transverse section. Species-specific patterns in conjunction with the numbers of ridges may serve to augment an array of diagnostic characters for species of Longistrongylus and contribute to increasingly accurate identification of female specimens. Among 5 of 6 species examined in the current study, the numbers of ridges in males was equal to or exceeded that observed in females, a pattern seen only in Africanastrongylus among the 15 genera of the Ostertagiinae. The differential numbers of ridges in males and females may represent another character among the suite of attributes that in part diagnose the genus Longistrongylus.

TI Comparison of Cationic and Unmodified Starches in Reactive Extrusion of
Starch-Polyacrylamide Graft Copolymers
SO JOURNAL OF POLYMERS AND THE ENVIRONMENT
LA English
DT Article
DE Starch; Graft copolymers; Reactive extrusion
AB Graft copolymers of starch and polyacrylamide (PAAm) were prepared using reactive extrusion in a corotating twin screw extruder. The effect of cationic starch modification was examined using unmodified and cationic dent starch (a parts per thousand 23% amylose) and waxy maize starch (a parts per thousand 2% amylose). For a fixed acrylamide/starch feed ratio, conversion, graft content, and grafting efficiency were essentially unaffected by starch type or modification. Cationic starch graft copolymers generally had lower molecular weight PAAm grafts compared to the unmodified starch, whereas amylose content had little or no significant effect. In addition, the frequency of grafting was higher with cationic starch. These results indicate that cationic modification of starch enhances formation of grafting sites, resulting in graft copolymers with more grafts of lower molecular compared to unmodified starch. Cationic modification may therefore be a way to tailor the properties of starch-PAAm graft copolymers.

AB Accompanied with the growth of Escherichia coli O157 : H7, there was a production of Shiga-like toxins by this pathogenic bacterium. Time-course studies indicated that the accumulation of toxins in the medium occurred mainly at the stationary phase of cell growth. The growth of E. coli O157 : H7 in culture media was not significantly affected by the presence of other bacteria, e.g., E. coli K-12, E. coli B6, Salmonella and Pseudomonas, even at high ratios. However, the production of Shiga-like toxins by E. coli O157 : H7 could be reduced by certain other bacteria, e.g., E. coli K-12, Pseudomonas aeruginosa but not Pseudomonas putida. These lowering effects by other background bacteria on the toxin production were also observed in experiments using regular and irradiated ground beef. The presence of analogs of quorum-sensing molecules such as homoserine lactone (HSL) and indole, in general decreased the production of toxins by E. coli O157 : H7. This decrease could be partially reversed by the presence of subinhibitory concentrations of antibiotics. The complex nature of the control of Shiga toxin production is discussed.
PRACTICAL APPLICATIONS
The toxic effects of pathogenic bacterium E. coli O157 : H7 are related to the production of Shiga-like toxins by the pathogen. Current studies on the influence of environmental factors such as cell density, presence of other bacteria, chemicals and food components indicated a complex influence on the production of Shiga-like toxins by E. coli O157 : H7. The observation that the presence of certain other bacteria could lower the ability of E. coli O157 : H7 to produce the toxins was of particular interest. The analyses of the results suggested several practical possibilities to lower the production of the toxins, and thus, the health risk of the pathogen to the general public.

AB Physical and sensory properties of several commercially available egg alternatives in a mayonnaise formulation were compared with a control formulation using whole egg. The egg alternatives included modified corn starch (MCS), wheat protein (WP), whey protein concentrate (WPC), whey protein isolate (WPI), WPI-gum blend (WPI-GB) and WPC-fenugreek gum blend (WPC-FGB). These egg alternatives were evaluated at 100% and 50% replacement. At 100% replacement, all egg alternatives except WPI exhibited significantly higher emulsion stability compared with the control. WPI-GB, WPC-FGB and WP at 100% exhibited significantly higher viscosity than the control. When used at 50% replacement an antagonistic relationship with egg yolk was observed for viscosity and firmness. At 100% replacement, WPI exhibited significantly higher firmness value than the control. Descriptive and consumer panels reported that MCS and WPC-FGB exhibited attributes similar, if not better than, the control.
PRACTICAL APPLICATIONS
The egg alternatives were used to replace egg as a functional ingredient in a model mayonnaise system. These alternatives can deliver functionality at a lower cost and can be incorporated to produce a suitable mayonnaise system especially modified corn starch and blends of whey protein concentrate-fenugreek gum blend. These results may help producers in formulating a new mayonnaise type.

AB Knowledge of sediment concentration is important in the study of streams and rivers. The work presented explores using high frequency (20 MHz) acoustic signal attenuation to measure the concentration of fine sediment particles (0.2-5.0 mu m) in a fluvial environment. A small laboratory tank with a pitch-catch transducer configuration measured a 35 dB change in signal level over a wide range of kaolinite and bentonite concentrations (1-14 g/l) over a range of distances (180-357 mm). The data suggest that a fixed distance of 180 mm between the transducers will be capable of measuring the entire range of concentrations.

AB Host avidity and deet repellency were measured in partially bloodfed Aedes albopictus provided 10% sucrose, water, or nothing when access to a human host was postponed for 1 to 72 h after a partial blood meal. Carbohydrate availability and postfeeding time influenced avidity. but partial blood meal effects were not significant. Mean host avidity declined significantly between hours 1 mid 6 (range 50-18%) but increased significantly between hours 24 (54%) and 72 (68%) alter a partial blood meal. Females provided sucrose solution and females denied sucrose or water showed the least (29%) and most (39%) host avidity, regardless of other treatment effects. The longest and shortest deet protection times were 8.5 h against females provided sucrose and 7.3 h against females denied sucrose or water, respectively. Denial of carbohydrate sustenance significantly increased host avidity and deet repellency in partially bloodfed female Ae. albopictus, whereas sucrose availability led to reduced host responding activity and decreased repellency of deet.

AB This article compares the collection characteristics of a new rotating impactor Florida Latham Bonds (FLB) sampler for ultrafine aerosols with a mimic of I he industry standard (Hock-type). The volume and droplet-size distribution collected by the rotating impactors were measured via spectroscopy and microscopy. The rotary impactors were colocated with an isokinetic air sampler for a total volume flux measurement and a laser diffraction instrument for droplet-size distribution measurement. The measured volumetric flux and droplet-size distribution collection efficiencies were compared across 3 wind speeds (1, 1.8, and 3.5 m/sec). The FLB sampler had higher flux collection efficiencies than the Hock-type sampler. The FLB sampler collected 89%. 87%, and 98% of the total volume available per unit area at 1, 1.8. and 3.5 m/sec. respectively. whereas the Hock-type sampler collected 68%, 19%, and 21% of across the same wind speeds. Changes in wind speed had less impact and resulted in less data variability for the FLB sampler.

AB Gonotrophic dissociation and fecundity in adult female Aedes albopictus affect the transmission of arbovirus and mosquito population dynamics. Female Ae. albopictus bloodfed on guinea pig and human hosts produced significantly (P < 0.05) higher number of eggs (80 and 82/female, respectively) than females fed on chicken (67 eggs/female). Fecundity in mosquitoes that took a double blood meal (chicken and guinea pig), a triple blood meal (3 separate guinea pigs), or mixed blood meals (chicken, guinea pig, and human) was significantly (P < 0.001) higher than in females fed on a single chicken or on 2 separate chickens (refeeding). Gonotrophic dissociation in laboratory colony of Ae. albopictus was first observed and its frequency decreased with multiple blood meals with triple feeding or mixed feeding (3 meals on 3 host types). Blood meal source did not significantly influence gonotrophic dissociation in Ae. albopictus.

AB A field study was conducted to explore the suitability of 5 pesticide deposition samplers for airborne spray and ground deposits from ultra-low-volume (ULV) space sprays. Samplers included horizontally stretched stationary cotton ribbons at 2 heights, rotating ribbon. rotating Teflon slides, and filter paper. Slides were also used for droplet-size analysis. A set of 7 samplers of each type was placed at 1, 7, 15, 25, 40 65, and 90 in from the spray line along the spray swath. Water and BVA13 oil with fluorescent dyes as tracers were sprayed with the use of a truck-mounted ULV sprayer at dusk and dawn. Results suggest that the horizontal and rotating cotton ribbons are best for quantification of airborne spray and filter paper is best for ground deposition collection. The rotating slide samplers only detected the BVA13 oil-based sprays.

AB To determine the effects of the addition of pure tocopherols to triacylglycerols, alpha, gamma, and delta tocopherols were added singly and in various combinations to stripped mid-oleic sunflower oil (SMOSUN). Tortilla chips were fried in the treated oils and then aged at ambient temperature to determine storage stability of the fried food. Frying oils were evaluated for total polar compounds (TPC) as an indicator of oil deterioration, and they were also analyzed for retention of tocopherols. To determine effects of tocopherols on fried-food stability, chips were evaluated for hexanal as an indicator of oxidative stability and for odor characteristics by a trained, experienced analytical sensory panel. Oils extracted from the tortilla chips were also analyzed for residual tocopherols. TPC were highest in the SMOSUN control with no additives followed by the SMOSUN containing only alpha tocopherol. The SMOSUN oil containing gamma tocopherol had the best fry life as indicated by the lowest TPC. Hexanal content and rancid odor intensity were highest in the chips fried in the SMOSUN control and in the SMOSUN containing only alpha tocopherol. The most stable tortilla chips were fried in SMOSUN containing all three (alpha, gamma, and delta) tocopherols; however, the lowest hexanal levels were measured when gamma and delta tocopherols were added at their highest concentrations.

AB This study compared the profiles of fatty acids, phytosterols, and polyamine conjugates in conventional commercial corn oil extracted from corn germ and in two "new-generation" corn oils: hexane-extracted corn fiber oil and ethanol-extracted corn kernel oil. The fatty acid compositions of all three corn oils were very similar and were unaffected by degumming, refining, bleaching, and deodorization. The levels of total phytosterols in crude corn fiber oil were about tenfold higher than those in commercial corn oil, and their levels in crude corn kernel oil were more than twofold higher than in conventional corn oil. When corn kernel oil was subjected to conventional degumming, refining, bleaching, and deodorization, about half of the phytosterols was removed, whereas when corn fiber oil was subjected to a gentle form of degumming, refining, bleaching, and deodorization, only about 10% of the phytosterols was removed. Finally, when the levels of polyamine conjugates (diferuloylputrescine and p-coumaroyl feruloylputrescine) were examined in these corn oils, they were only detected in the ethanol-extracted crude corn kernel oil, confirming earlier reports that they were not extracted by hexane, and providing new information that they could be removed from ethanol-extracted corn kernel oil by conventional degumming, refining, bleaching, and deodorizing.

AB Sediment oxygen demand (SOD) is considered a critical and dominant sink for dissolved oxygen (DO) in many river systems including blackwater streams and is often poorly investigated or roughly estimated in oxygen budgets. The purposes of this study are to (1) characterize and document the magnitude and variability of SOD in representative instream swamps found on the Georgia Coastal Plain; (2) predict SOD from more readily measured parameters such as soil, sediment, and litter organic carbon; and (3) obtain an accurate representation of SOD values within this understudied habitat to help improve water quality models and the continued development of DO as an appropriate water quality standard. Results show SOD rates ranging from 0.491 to 14.189 g O(2)/m2/day, up to 18 times higher than values reported for southeastern sandy-bottomed streams and suggest that instream swamps are repositories of large amounts of organic matter and are thus areas of intense oxygen demand and a major factor in determining the oxygen balance of the watershed as a whole. These areas of intense oxygen demand in relatively unimpacted areas indicate that low DO concentrations may be a natural phenomenon. SOD rates were significantly correlated (alpha = 0.05) with a number of sediment parameters, with organic carbon and total organic carbon being the best predictors of SOD rate. When developing water quality models, managers should pay closer attention to the influence of SOD as it plays a critical role in determining DO levels within instream swamps and the river system.

AB Fecundity of mosquitoes can vary with many factors and can have a strong effect on population growth. This study reports the effects of body size, blood meal size, and age on the reproductive output of nulliparous Culex quinquefasciatus, a vector of arboviruses and other pathogens. Mated adult female mosquitoes from a colony were reared under standard conditions and fed on chickens at different ages post-eclosion. Blood meal size and wing length were recorded, as well as the number of eggs in the first-cycle egg raft. Each of these factors had a significant influence on fecundity considered in a simple regression context. Multiple regression analysis revealed a significant interaction effect between age and body size on fecundity. Up to 13 days of age, fecundity was positively correlated with body size, but in mosquitoes older than 13 days, this relationship was not significantly different from zero. These results are discussed in terms of the known physiology of this and other species.

AB Sugarcane mosaic disease (SMD) caused by the Sugarcane mosaic virus (SCMV), Sorghum mosaic virus (SrMV) and Sugarcane streak mosaic virus (SCSMV) and sugarcane yellow leaf disease (SYLD) caused by the Sugarcane yellow leaf virus (SCYLV) are the two most prevalent and economically important viral diseases of sugarcane. In this study, a one-step quadruplex reverse transcription (RT)-PCR method that employed virus-specific primers was developed for the simultaneous detection and differentiation of SCMV, SrMV, SCSMV and SCYLV. Several sets of primers for each target virus were evaluated for their sensitivity and specificity by simplex and quadruplex RT-PCR. The optimum primer combinations and concentrations, RT temperature and time, and PCR annealing temperature and extension time were determined for the quadruplex RT-PCR. The assay was then validated using sugarcane samples affected with SMD and/or SYLD collected from sugarcane breeding fields and farmers' fields in southern China. (C) 2009 Elsevier B.V.

AB Multiplex reverse transcription and polymerase chain reaction (PCR) methods were developed to detect Solenopsis invicta viruses -1, -2, and -3 simultaneously in their host, the red imported fire ant, S. invicta. cDNA synthesis was conducted in a single reaction containing an oligonucleotide primer specific for each virus. Multiplex PCR was subsequently conducted with oligonucleotide primer pairs specific for each virus. The method was specific and sensitive, capable of detecting as few as 500 copies of the viral genomes consistently. Specificity was verified by PCR and amplicon sequencing. The method was evaluated against field-collected samples of ant workers from colonies in Argentina (n = 135 ant colonies) and the United States (n = 172 ant colonies). The prevalence of each virus in fire ant colonies varied considerably from site to site. A number of colonies exhibited multiple virus infections. However, the multiple SINV infection rate was lower than for single infections. Comparison of viral infection prevalence between S. invicta colonies in Argentina and the U.S. showed no statistical differences, regardless of infection category. This method is anticipated to facilitate epidemiological and related studies concerning the S. invicta viruses in fire ants. Published by Elsevier B.V.

Although plantaris (PLA) muscle hypertrophy was attenuated by aging, mTOR phosphorylation was 44% and 35% greater in Y SA and O SA compared with CON (p =.038). Ribosomal protein S6 phosphorylation was 114% and 24% higher in Y SA and O SA compared with CON (p =.009). Eukaryotic initiation factor 2B epsilon phosphorylation was 33% and 9% higher in Y SA and O SA compared with CON (p =.04). Translational signaling in young adult and aged plantaris muscle is equally responsive to chronic overload.

AB Variation in the size of home range of white-tailed deer (Odocoileus virginianus) has broad implications for managing populations, agricultural damage, and disease spread and transmission. Size of home range of deer also varies seasonally because plant phenology dictates the vegetation types that are used as foraging or resting sites. Knowledge of the landscape configuration and connectivity that contributes to variation in size of home range of deer for the region is needed to fully understand differences and similarities of deer ecology throughout the Midwest. We developed a research team from four Midwestern states to investigate how size of home range of deer in agro-forested landscapes is influenced by variations in landscape characteristics that provide essential habitat components. We found that for resident female deer, annual size of home range in Illinois (mean = 0.99 km(2)), Michigan (mean = 1.34 km(2)), Nebraska (mean = 1.20 km(2)), and Wisconsin (mean = 1.47 km(2)) did not differ across the region (F (3,175) = 0.42, P = 0.737), but differences between agricultural growing and nongrowing periods were apparent. Variables influencing size of home range included: distance to forests, roads, and urban development from the centroid of deer home range, and percent of crop as well as four landscape pattern indices (contrast-weighted edge density, mean nearest neighbor, area-weighted mean shape index, and patch size coefficient of variation). We also identified differences in model selection for four landscapes created hierarchically to reflect levels of landscape connectivity determined from perceived ability of deer to traverse the landscape. Connectivity of selected forested regions within agro-forested ecosystems across the Midwest plays a greater role in understanding the size of home ranges than traditional definitions of deer habitat conditions and landscape configuration.

AB Aims:
The major objective of this study was to determine the effects of low levels of Escherichia coli O157:H7 contamination on plant by monitoring the survival of the pathogen on the rhizosphere and leaf surfaces of lettuce during the growth process.
Methods and Results:
Real-time PCR and plate counts were used to quantify the survival of E. coli O157:H7 in the rhizosphere and leaf surfaces after planting. Real-time PCR assays were designed to amplify the stx1, stx2 and the eae genes of E. coli O157:H7. The detection limit for E. coli O157:H7 quantification by real-time PCR was 2 center dot 4 x 103 CFU g-1 of starting DNA in rhizosphere and phyllosphere samples and about 102 CFU g-1 by plate count. The time for pathogens to reach detection limits on the leaf surface by plate counts was 7 days after planting in comparison with 21 days in the rhizosphere. However, real-time PCR continued to detect stx1, stx2 and the eae genes throughout the experimental period.
Conclusion:
Escherichia coli O157:H7 survived throughout the growth period as was determined by real-time PCR and by subsequent enrichment and immunomagnetic separation of edible part of plants.
Significance and impact of the Study:
The potential presence of human pathogens in vegetables grown in soils contaminated with E. coli O157:H7 is a serious problem to our national food supply as the pathogen may survive on the leaf surface as they come in contact with contaminated soil during germination.

AB Stocking density is an important aspect of transport, which could affect animal health and welfare, especially in pigs simultaneously experiencing weaning stress. The objective of this research was to evaluate the effect of three different space allowances on the physiology and behavior of weaned pigs during transport. A commercial semi-trailer with compartments that provided 0.05, 0.06 and 0.07 m(2)/pig was used throughout the study. All three space allowances were represented on both the upper and lower decks during each replicate. A constant of 100 pigs were loaded into each experimental compartment. Pigs were then transported for 112.5 +/- 6.5 min to the wean-to-finishing site using the same route for each replication. This experiment was replicated 4 times. The experimental unit was the compartment Prior to and after transport blood samples were taken from a sub-set of pigs (n=32 pigs/space allowance) for analysis of physiological and immune measures, and body weights and lesion scores were also recorded. Data loggers were fitted inside the trailer to record temperature, humidity, and wind speed. Cameras were placed in each experimental compartment to record behavior and postures of pigs during transport. The frequencies of standing, lying. sitting, standing-rearing on another pig, lying/huddling on top of another pig, total active and total inactive behaviors were recorded using 1-min scan samples during the entire duration of transport. Inside trailer temperature ranged from -2.4 to 21.7 degrees C and inside trailer relative humidity ranged from 28.4 to 89.2% during transport Cortisol, the neutrophil: lymphocyte (N:L) ratio, blood urea nitrogen, total bilirubin. total protein. albumin, aspartate aminotransferase, and creatine kinase were higher (p<0.05) in pigs after transport regardless of space allowance. Skin lesions were more severe (p<0.001) in pigs after transport regardless of space allowance. Pigs spent more (p<0.001) time active during the first 75 min of transport compared with the last 30 min, regardless of space allowance. Pigs spent less (p<0.01) time standing on another pig during transport at 0.07 m(2)/pig compared with pigs transported at 0.06 m(2)/pig. Higher cortisol concentrations and N:L ratio in weaned pigs after transport suggest that these pigs experienced stress, however space allowance did not appear to influence this response. Space allowances of 0.05. 0.06 or 0.07 m(2)/pig did not differentially influence pig wellbeing during a 112-min transport period as measured by changes in physiological measures.

AB Based on dietary intake recommendations, magnesium deficiency commonly occurs throughout the world. However, widespread pathological conditions induced by dietary magnesium deficiency have not been identified. This discrepancy may be caused by other dietary factors ameliorating or exacerbating the response to a marginal magnesium deficiency and/or the length of the deficiency. Thus, a study was performed to determine whether the n-6/n-3 fatty acid composition of the diet affects the response to marginal magnesium deprivation, and whether the effect was dependent upon the length of deprivation. Weanling female rats were fed diets containing 250 mg/kg magnesium in a factorial arrangement with dietary variables of supplemental magnesium at 0 or 250 mg/kg (total of 250 or 500 mg/kg) and fat sources of 75 g/kg corn oil or 65 g/kg fish (menhaden) oil plus 10 g/kg linoleic acid. After 8 and 12 weeks on their respective diets, each rat was placed in a metabolic cage for a 16-hour collection of urine. After 13 weeks, the rats were anesthetized with ether for the collection of plasma and organs. Marginal magnesium deficiency was confirmed by decreased urinary excretion and femur, tibia and vertebrae concentrations of magnesium. Dietary oil influenced the effect of marginal magnesium deficiency on magnesium metabolism, distribution and oxidative stress indicators. Fish oil, but not corn oil, significantly decreased urinary magnesium excretion and increased kidney magnesium concentration. Femur magnesium was significantly decreased by marginal magnesium deficiency in rats fed fish oil but not in rats fed corn oil, and liver magnesium concentration was decreased by fish oil. Marginal magnesium deficiency increased plasma extracellular superoxide dismutase and cysteine (component of glutathione) in rats fed corn oil but not in rats fed fish oil. Urinary prostaglandin E(2) excretion was significantly decreased by marginal magnesium deficiency at 8 weeks, but not at 12 weeks; an increase between weeks 8 and 12 in marginally magnesium-deficient rats fed fish oil caused this change in significance. The findings show that the dietary fatty acid composition affects the response of rats to marginal magnesium deprivation. The findings also indicate that dietary or physiological factors affecting oxidative stress could affect the response to marginal magnesium deficiency, and that a response to a dietary change that takes time to develop, such as an increase in dietary n-3 fatty acids, may result in signs of marginal deficiency being different over time.

AB A large proportion of South African feedlot cattle are crossbreds of Brahman (BrX, Bos indicus). and Simmental (SiX. Bos taurus). A sample of 20 grain fed bulls from each of these crossbreeds Was used to compare meat quality with that of the small frame indigenous Nguni (NgX, Sanga) by evaluating a variety of biochemical and genetic parameters previously shown to be associated with meat tenderness. Shear force values were generally high (5.6 kg average at 14 days postmortem), with SiX animals higher than BrX or NgX (P = 0.051) despite higher calpastatin:calpain ratio in BrX (P < 0.05). Calpain activity and cold shortening were both correlated with tenderness for all classes. The sample size was too small to accurately estimate genotypic effects of previously published markers in the CAST and CAPN I genes, but the allele frequencies suggest that only modest progress Would be possible in these South African crossbreds using these markers.

AB Beef knuckles (n = 150) and center-cut top sirloin butts (n = 150) were used to determine portion-controlled steak cutting yields, palatability characteristics, and consumer acceptance of rectus femoris (RF), vastus lateralis (VL). and gluteus medius (CM) steaks. Steak yields were higher (P < 0.05) for top sirloins than knuckles. Trained sensory panel ratings for overall tenderness, juiciness, and flavor were similar between RF and GM. Consumer panel ratings for tenderness and juiciness were higher (P < 0.05) for GM than RF; however, consumer perceptions of overall like and flavor were similar for GM and RF. Vastus lateralis received lower (P < 0.05) trained panel and consumer ratings for all traits than either RF or GM. Palatability of VL will need improvement to be a viable foodservice offering. Yet, these data suggest that RF would amply substitute for GM in foodservice settings, and that knuckle steak yields would be adequate for foodservice applications. Published by Elsevier Ltd.

AB Aflatoxins produced by Aspergillus flavus are potent carcinogens that contaminate agricultural crops. Recent efforts to reduce aflatoxin concentrations in crops have focused on biological control using nonaflatoxigenic A. flavus strains AF36 (=NRRL 18543) and NRRL 21882 (the active component of afla-guard (R)). However, the evolutionary potential of these strains to remain nonaflatoxigenic in nature is unknown. To elucidate the underlying population processes that influence aflatoxigenicity, we examined patterns of linkage disequilibrium (LD) spanning 21 regions in the aflatoxin gene cluster of A. flavus. We show that recombination events are unevenly distributed across the cluster in A. flavus. Six distinct LD blocks separate late pathway genes aflE, aflM, aflN, aflG, aflL, aflI and aflO, and there is no discernable evidence of recombination among early pathway genes aflA, aflB, aflC, aflD, aflR and aflS. The discordance in phylogenies inferred for the aflW/aflX intergenic region and two noncluster regions, tryptophan synthase and acetamidase, is indicative of trans-species evolution in the cluster. Additionally, polymorphisms in aflW/aflX divide A. flavus strains into two distinct clades, each harbouring only one of the two approved biocontrol strains. The clade with AF36 includes both aflatoxigenic and nonaflatoxigenic strains, whereas the clade with NRRL 21882 comprises only nonaflatoxigenic strains and includes all strains of A. flavus missing the entire gene cluster or with partial gene clusters. Our detection of LD blocks in partial clusters indicates that recombination may have played an important role in cluster disassembly, and multilocus coalescent analyses of cluster and noncluster regions indicate lineage-specific gene loss in A. flavus. These results have important implications in assessing the stability of biocontrol strains in nature.

AB Genetic assignment methods provide an appealing approach for characterizing dispersal patterns on ecological time scales, but require sufficient genetic differentiation to accurately identify migrants and a large enough sample size of migrants to, for example, compare dispersal between sexes or age classes. We demonstrate that assignment methods can be rigorously used to characterize dispersal patterns in a marbled murrelet (Brachyramphus marmoratus) population from central California that numbers approximately 600 individuals and is only moderately differentiated (F-ST similar to 0.03) from larger populations to the north. We used coalescent simulations to select a significance level that resulted in a low and approximately equal expected number of type I and II errors and then used this significance level to identify a population of origin for 589 individuals genotyped at 13 microsatellite loci. The proportion of migrants in central California was greatest during winter when 83% of individuals were classified as migrants compared to lower proportions during the breeding (6%) and post-breeding (8%) seasons. Dispersal was also biased toward young and female individuals, as is typical in birds. Migrants were rarely members of parent-offspring pairs, suggesting that they contributed few young to the central California population. A greater number of migrants than expected under equilibrium conditions, a lack of individuals with mixed ancestry, and a small number of potential source populations (two), likely allowed us to use assignment methods to rigorously characterize dispersal patterns for a population that was larger and less differentiated than typically thought required for the identification of migrants.

AB The present study describes the cloning and functional characterization of avian interleukin (IL)-19, a cytokine that, in mammals, alters the balance of Th1 and Th2 cells in favor of the Th2 phenotype. The full-length avian IL-19 gene, located on chromosome 26, was amplified from LPS-stimulated chicken monocytes, and cloned into both prokaryotic (pET28a) and eukaryotic (pcDNA3.1) expression vectors. The confirmed avian IL-19 amino acid sequence has 66.5% homology with human and murine IL-19, with a predicted protein sequence of 176 amino acids. Analysis of avian IL-19 amino acid sequence showed six conserved, structurally relevant, cysteine residues as found in mammals, but only one N-glycosylation residue. The recombinant IL-19 (rChIL-19) expressed in the prokaryotic system was purified by Ni(+)-resin column followed by endotoxin removal. Using purified avian rChIL-19, expression of Th2 cytokines was measured in splenocytes using quantitative real-time PCR (qRT-PCR). In the presence of rChIL-19, expression levels of IL-4 and IL-13, as well as IL-10, were significantly increased after 6- and 12 h treatments. This was confirmed by treating splenocytes with supernatants from IL-19 transfected cells. Also, avian monocytes incubated with rChIL-19 displayed increased expression of IL-1 beta, IL-6, and IL-19. This study represents the first report for the cloning, expression, and functional characterization of avian IL-19. Taken together, avian IL-19 function seems to be conserved and similar to that of mammals and may play an important role in responses to intracellular poultry pathogens like bacteria and protozoa.

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

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

AB In plants, ethylene and jasmonate control the defense responses to multiple stressors, including insect predation. Among the defense proteins known to be regulated by ethylene is maize insect resistance 1-cysteine protease (Mir1-CP). This protein is constitutively expressed in the insect-resistant maize (Zea mays) genotype Mp708; however, its abundance significantly increases during fall armyworm (Spodoptera frugiperda) herbivory. Within 1 h of herbivory by fall armyworm, Mir1-CP accumulates at the feeding site and continues to increase in abundance until 24 h without any increase in its transcript (mir1) levels. To resolve this discrepancy and elucidate the role of ethylene and jasmonate in the signaling of Mir1-CP expression, the effects of phytohormone biosynthesis and perception inhibitors on Mir1-CP expression were tested. Immunoblot analysis of Mir1-CP accumulation and quantitative reverse-transcriptase polymerase chain reaction examination of mir1 levels in these treated plants demonstrate that Mir1-CP accumulation is regulated by both transcript abundance and protein expression levels. The results also suggest that jasmonate functions upstream of ethylene in the Mir1-CP expression pathway, allowing for both low-level constitutive expression and a two-stage defensive response, an immediate response involving Mir1-CP accumulation and a delayed response inducing mir1 transcript expression.

AB Trichoderma species are usually considered soil organisms that colonize plant roots, sometimes forming a symbiotic relationship. Recent studies demonstrate that Trichoderma species are also capable of colonizing the above ground tissues of Theobroma cacao (cacao) in what has been characterized as an endophytic relationship. Trichoderma species can be re-isolated from surface sterilized cacao stem tissue, including the bark and xylem, the apical meristem, and to a lesser degree from leaves. SEM analysis of cacao stems colonized by strains of four Trichoderma species (Trichoderma ovalisporum-DIS 70a, Trichoderma hamatum-DIS 219b, Trichoderma koningiopsis-DIS 172ai, or Trichoderma harzianum-DIS 2190 showed a preference for surface colonization of glandular trichomes versus non-glandular trichomes. The Trichoderma strains colonized the glandular trichome tips and formed swellings resembling appresoria. Hyphae were observed emerging from the glandular trichomes on surface sterilized stems from cacao seedlings that had been inoculated with each of the four Trichoderma strains. Fungal hyphae were observed under the microscope emerging from the trichomes as soon as 6 h after their isolation from surface sterilized cacao seedling stems. Hyphae were also observed, in some cases, emerging from stalk cells opposite the trichome head. Repeated single trichome/hyphae isolations verified that the emerging hyphae were the Trichoderma strains with which the cacao seedlings had been inoculated. Strains of four Trichoderma species were able to enter glandular trichomes during the colonization of cacao stems where they survived surface sterilization and could be re-isolated. The penetration of cacao trichomes may provide the entry point for Trichoderma species into the cacao stem allowing systemic colonization of this tissue.

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

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

AB Cucumber is an economically important crop as well as a model system for sex determination studies and plant vascular biology. Here we report the draft genome sequence of Cucumis sativus var. sativus L., assembled using a novel combination of traditional Sanger and next-generation Illumina GA sequencing technologies to obtain 72.2-fold genome coverage. The absence of recent whole-genome duplication, along with the presence of few tandem duplications, explains the small number of genes in the cucumber. Our study establishes that five of the cucumber's seven chromosomes arose from fusions of ten ancestral chromosomes after divergence from Cucumis melo. The sequenced cucumber genome affords insight into traits such as its sex expression, disease resistance, biosynthesis of cucurbitacin and 'fresh green' odor. We also identify 686 gene clusters related to phloem function. The cucumber genome provides a valuable resource for developing elite cultivars and for studying the evolution and function of the plant vascular system.

AB Soybean cyst nematode (Heterodera glycines) is a major yield limiting pest in all major soybean producing countries. In the last decade genetically modified soybean tolerant to glyphosate has become widely planted and postemergence application of glyphosate has increased exponentially. Genetically modified crops may affect nontarget microorganisms, either directly or indirectly as in the case of glyphosate application to tolerant crops. Glyphosate translocates to soybean roots where it might affect metabolic sinks such as syncytia produced by Heterodera glycines. In 2002-2004 glyphosate tolerant soybean DSR 320 susceptible to H. glycines and DSR 327 resistant to H. glycines were grown in three different fields and either sprayed with glyphosate at the recommended rate and time of application or not sprayed. Nematode reproduction and soybean yield were determined. In all three years, Pf and Pf/Pi were significantly greater on DSR 320 when compared with DSR 327. In 2004, when Pi exceeded the damage threshold, there was a cultivar x glyphosate interaction for Pf on DSR 320 with greater numbers of eggs recovered from glyphosate treated DSR 320. In 2002 and 2003 Pi was below the damage threshold and no differences in yield occurred between the resistant and susceptible cultivars. However, in 2003 a significant cultivar x glyphosate interaction was observed for yield of DSR 320. In 2004 a significant difference in yield between DSR 320 and DSR 327 was observed. Glyphosate application affected Pf of H. glycines eggs in 2004, the only year Pi exceeded the damage threshold. However, the increase Pf did not translate into crop loss.

AB A study was conducted to characterize the morphology, enzymatic profile, and host preference of four isolates of the peach root-knot nematode, Meloidogyne floridensis. No morphological or biochemical differences were observed among the four isolates. Each isolate showed some mean variability in morphometrics values, but overlapped in their range values (P > 0.05). In total, 1,027 females extracted from peach, pepper, tobacco, and tomato did not differ in their isozyme phenotype for esterase and malate dehydrogenase, and matched those reported in the original description. In host differential tests all four isolates of M. floridensis exhibited the same reaction as that of M. incognita race 2, with pepper, tobacco, tomato and watermelon being susceptible, and cotton and peanut, resistant. In comparative host status studies, both root-knot nematode resistant and susceptible peach cultivars were susceptible to all four isolates. Both resistant and susceptible cultivars of corn, pepper, soybean, and tomato were evaluated. All four isolates of M. floridensis reproduced poorly, but were able to overcome the resistance of the Mi-1 gene in tomato cv. Crista. Two isolates reproduced poorly, but were not affected by the N gene resistance in the pepper cv. Charleston Belle, whereas two isolates reproduced well on this cultivar. Both the root-knot nematode resistant corn cv. Mp 710 and susceptible cv. Dixie 18 were susceptible to all four isolates; whereas, both the resistant soybean cv. Forrest and susceptible cv. S64-J1 were immune to all four isolates of M. floridensis.

AB The effect of the interaction between Meloidogyne incognita and Pratylenchus vulnus on nematode reproduction and vegetative growth of Lovell peach was studied in field microplots. Pratylenchus vulnus suppressed the population density of M. incognita second-stage juveniles, whereas the presence of M. incognita did not affect the population density of P. vulnus in soil. Above-ground tree growth, as measured by trunk diameter 12 and 24 months following inoculation, was reduced in the presence of M. incognita. Differences in root growth as related to nematode treatment were detected 26 months after inoculation. Root growth was reduced in the presence of the two nematode species together than P. vulnus alone, but not when compared to M. incognita alone. There was a greater negative impact on vegetative growth of peach seedlings growing in M. incognita-infested soil than in P. vulnus-infested soil.

AB Radiation exchange at the surface plays a critical role in the sui face energy balance, plant microclimate, and plant growth. The ability to simulate the surface energy balance and the microclimate within the plant canopy is contingent upon simulation of the surface radiation exchange. A validation and modification exercise of the Simultaneous Heat and Water (SHAW) model was conducted for simulating the sui face short-wave and long-wave radiation exchange over and within wheat, maize and soya bean plant canopies using data collected at Yucheng in the North China Plain and neat Ames. Iowa Whereas model testing was limited to monocultures and mixed canopies of green and senesced leaves, methodologies were developed for simulating short-wave and long-wave radiation fluxes applicable to a multi-species, multi-layer plant canopy Although the original SHAW model slightly under predicted reflected solar radiation with a mean bias en or (MBE) of -5 to -10 W m(-2), one would conclude that the simulations were quite reasonable if within-canopy measurements were not available However, within-canopy short-wave radiation was considerably under estimated (MBE of approximately -20 W m(-2)) by the original SHAW model Additionally, leaf temperatures tended to be overpredicted (MBE = +0 76 degrees C) near the top of the canopy and underpredicted near the bottom (MBE = -1 12 degrees C) Modification to the SHAW model reduced MBE of above canopy reflected radiation to -1 to -6 W m(-2) and within-canopy radiation simulations to approximately -6 W m(-2). bias in leaf temperature was reduced to less than 0 4 degrees C Model modifications resulted in essentially no change in simulated evapotranspiration lot wheat. 4.5% lower for maize and 1% higher for soya bean Alternative approaches for simulating canopy transmissivity to diffuse radiation were tested in the modified version and had a minor influence on simulated short-wave radiation, but made almost no difference in simulated long-wave radiation or evapotranspiration Modifications to the model should lead to more accurate plant microclimate simulation, further work is needed to evaluate their influence (C) 2009 Royal Netherlands Society for Agricultural Sciences Published by Elsevier B V All rights reserved

AB Understanding plant development and architecture has been aided by the phytomer concept The phytomer, usually considered a vegetative unit of a leaf, node. Inter node, axillary bud, and occasionally nodal oats. has been extended to the inflorescence with units repeated within and among shoots For many reasons including insufficient knowledge of phytomer dynamics or specific modelling objectives, city models may not fully incorporate phytomer concepts For instance, commonly, some phytomers are aggregated into a single component such as an inflorescence component Continuing development and maturing of object-oriented(OO) design provides opportunities for better representing phytomer concepts in crop models and integrating approaches using varying scales of resolution Use of the structural Composite Design Pattern (CDP) in an OO plant design facilitates combining scales with a mixture of single and aggregated phytomers for different components This paper uses winter wheat (Triticum aestivum L) to (1) illustrate building the entire plant canopy by the appearance. growth, and death of phytomer units, (2) translate this botanical abstraction into an OO design using the COP, (3) use the CDP to facilitate a mixture of scales, and (4) present results of a proof-of-concept prototype, CANON. named because the interplay of repeating phytomers is analogous to the repeating melodies of a canon musical composition CANON implements the phytomer concept of an entire canopy (both vegetative and reproductive phytomers) into an OO design using the CDP This pattern facilitated the combination of simulation scales from individual reproductive phytomers to an aggregated inflorescence Quantification of phytomer concepts for winter wheat was primarily derived from the SHOOTGRO model, with the addition of a simple aggregated inflorescence sub-model derived from the APSIM model The CANON prototype was able to simulate the appearance, growth, and senescence of phytomers on individual shoots of the plant comprising the plant canopy. Importantly, CANON was able to incorporate legacy code with a lower scale of resolution than the phytomer CANON demonstrates an OO design to simulate plant canopy development and growth ham the sub-phytomer to whole-plant level, allowing flexibility in meeting different model objectives and available knowledge of processes (C) 2009 Royal Netherlands Society for Agricultural Sciences.

AB Much of agricultural research has the ultimate goal of enhancing our ability to predict phenotypes (P) based upon knowledge of genotypes (C). environment (E) and management (M) in order to quantitatively predict phenotypes (P). also known as the GEM-to-P problem Ecophysiological models are powerful tools for quantitatively predicting phenotypes in terms of environment and management, but their representations of genetic effects are very simplistic Genomics offers promising avenues to reduce model uncertainty by improving descriptions of the genetic differences among cultivars This paper reviews use of genetics and genomics with emphasis on wheat (Triticum aestivum L.), sorghum (Sorghum bicolor [L] Moench) and common bean (Phaseolus vulgaris L) Cultivar-specific parameters, such as for photoperiod sensitivity or grain size, are often problematic because their values are estimated empirically from field studies and because the assumed physiology is inaccurate Estimates based on genotypic data should be more reliable than estimates from phenotypic data since environmental vat talon is eliminated. Using ecophysiological models for wheat, sorghum and common bean, cultivar coefficients wet e estimated using linear functions for gene effects For all three crops, simulations with gene-based coefficients were similar to those from conventional coefficients Wider use of this approach has been limited by the number of loci that have been characterized for readily modelled traits. However, data limitations are diminishing as genomic tools provide robust characterization of genes such as the Vrn and Ppd series in wheat Genomics also can contribute to understanding of how processes should be represented in models Examples include determining the end of the juvenile phase. characterizing interactive effects of temperature on photoperiod sensitivity, improving how tiller development is modelled, and estimating carbon costs of low-lignin traits for bioenergy crops. The merger of ecophysiological models with genomics, however. will not happen spontaneously. Modellers must broaden their understanding of genomics and related fields, while developing effective collaborations with the plant biology community (C) 2009 Royal Netherlands Society for Agricultural Sciences Published by Elsevier B V All rights reserved

AB A challenge for crop simulation modelling is to incorporate existing and rapidly emerging genomic information into models to develop new and improved algorithms The objective of this effort was to simulate plant height in winter wheat (Triticum aestivum L) across a range of environments in Nebraska using genetic information Plant height is influenced by major genes that are discrete and well characterized genetically and phenotypically. Although plant height is a complex trait, it is far simpler than many other traits Two datasets were used in this study, one from a study where final plant heights were measured at five locations across Nebraska in two years (dataset 1) and another study where plant height was measured 13 times before anthesis in one year at one location for one genotype (dataset 2) The crop simulation model CropSyst was modified by incorporating a different phenology algorithm and adding a plant height algorithm The plant height algorithm was based on the ratio of the mean optimum final height of a height class (tall semi-dwarf, semi-dwarf. short semi-dwarf) to the mean optimum final heights for two tall cultivars, an environmental index based on the fraction of transpirable soil water, and the development stage Final plant heights were simulated reasonably well for the different height classes with a root mean square error (RMSE) of 7 3 cm (dataset 1). For dataset 2, the simulated plant height of a short semi-dwarf line was always greater than the observed plant height, resulting in observed and simulated final plant heights of 82 and 88 cm, respectively (RMSE = 8 8 cm) The least accurate simulations, in which heights were overpredicted, occurred when precipitation during the growing season was above aver age (C) 2009 Published by Elsevier B V on behalf of Royal Netherlands Society for Agricultural Sciences.

AB The relationship between the movement of small (<150-mm) Dolly Varden Salvelinus malma and cutthroat trout Oncorhynchus clarkii and stream discharge is not well known in streams of southeast Alaska. We measured movement in a small headwater stream using passive integrated transponder (PIT) tags and stationary antennas to record time and date of movement. Fish with PIT tags were detected by transceivers and stationary antennas in the stream. The date and time of detection at an antenna were matched with stream discharge (m(3)/s) at the same date and time. Most Dolly Varden moved upstream during late summer and early fall. Most cutthroat trout movement was in May, and movement declined through the summer. Few fish moved during the winter. Most fish moved within a narrow discharge range, with a few moving at higher discharges. More than 97% of fish from both species were detected as moving upstream at discharges below the 5% exceedance level during the 4-year period of discharge measurements. Dolly Varden and cutthroat trout moved throughout the entire length of usable habitat in the stream. Connectivity throughout watersheds even within headwater streams is important and can be maintained for these species by use of road crossings that ensure passage over a range of flow conditions such as those described here.

AB Silvicultural strategies are often planned to favor the growth and survival of desired species until they reach a competitive position in the upper canopy. Once desired species reach the upper canopy, they can persist and provide a variety of benefits for decades. Later, they can serve as a source of natural regeneration for sustaining species composition. Although information is available for promoting desired advance seedlings in the understory of mature stands and culturing desired saplings in the upper canopy of young stands, additional information is needed on promoting desired species at mid-rotation, when the stand first reaches commercial size classes. Crown class transition rates for a total of 2,668 white and chestnut oaks, northern red oak, scarlet and black oaks, yellow-poplar, red maple, blackgum, and black birch were observed for 20 years in a 53-year-old central Appalachian mixed-hardwood stand. Treatments included three residual stand densities after commercial thinning and an unthinned control. In general, the thinning treatments reduced mortality, increased crown class retention rates of codominant trees, and increased the ascension rates of trees in the intermediate crown class. After thinning, codominant trees exhibited the crown class stability of dominant trees, and intermediate trees exhibited greater survival and ascension to the upper canopy compared with unthinned controls. Very few suppressed trees improved canopy position in thinning treatments; however, thinning did tend to reduce mortality of these trees. Crown class transition rates are presented to help forest managers understand how commercial thinning treatments can affect the composition of the upper canopy in the latter stages of stand development.

AB New England forest managers are faced with numerous environmental issues, such as global warming, nutrient depletion, and species declines that could influence the choice of appropriate silvicultural techniques and objectives. On the Bartlett Experimental Forest, New Hampshire, 70 years of change on more than 400 remeasured cruise plots by elevation classes ranging from 600 to 2,700 ft showed no evidence of environmental impacts. The major, and only dominant, agent of change was natural succession. Time-tested silvicultural approaches remain valid.

AB Entire yellow starthistle, Centaurea solstitialis L. (Asteraccae), plants were harvested from three southeastern Washington sites in September 2004 for seed head dissections to assess intra-plant patterns in the spatial distribution of the introduced false peacock fly, Chaetorellia succinea (Costa), and peacock fly, Chaetorellia australis Hering (Diptera: Tephritidae). Thirty plants were partitioned into three height classes and collected at each site, spanning the longitudinal range of yellow starthistle in Washington. Seed head canopies were stratified into three vertical sections and individual heads were dissected to determine bioagent occupation. Logistic regression analysis using a binary logit model was performed on data collected from each of the three sites separately due to varying site effects. Explanatory variables included plant height, plant width, plant canopy stratum (apical, mid, basal), and presence of other bioagents within a head. 'Other bioagents' detected include the yellow starthistle hairy weevil, Eustenopus villosus (Boheman) (Coleoptera: Curculionidae), the yellow starthistle bud weevil. Bangasternus orientalis Capiomont (Coleoptera: Curculionidae), the yellow starthistle flower weevil, Larinus curtus Hochhut (Coleoptera: Curculionidae), and the yellow starthistle gall fly, Urophora sirunaseva (Hering) (Diptera: Tephritidae). Using Chaetorellia spp. presence its the response variable, models were significant for the western-most site in Klickitat Co. (chi(2) = 35.66, df = 5. P<0.0001, n = 2,783), and the eastern-most site in Asotin Co. (chi(2) = 17.93, df = 5. P = 0.0030, n = 939). but not for the central site in Benton Co. (chi(2) = 9.44. df = 5, P = 0.0929. it = 1 MO). The one consistently significant site-wide predictor of Chaetorellia spp. occupation was the presence of 'other bioagents.' The frequent co-occurrence of Chaetorellia spp. and, in particular, E. villosus at the sampling sites suggests potentially competitive interactions between these insects.

AB Downed wood provides important faunal microhabitat in forests for numerous invertebrate taxa, small mammals and amphibians. Habitat suitability of downed wood as refugia is an increasing concern in managed Pacific Northwest forests, where overstory reduction may result in both reduced downed wood recruitment and increased temperatures within logs. We examined temperature profiles in western Oregon to assess differences in thermal regimes of logs and soil relative to Summer air temperature extremes and their implications with respect to habitat suitability for plethodontid salamanders. Temperature profiles of small- (0.3-0.45 m) and large- (0.7-1.0 m) diameter logs, as well as ambient soil and air temperatures, were measured in a 60-year-old forest stand at two different positions (0-5 m and 35-40 m from stream edge) in three case studies: 1) along a headwater stream with a narrow riparian buffer (similar to 6 m) and moderate upslope thinning; 2) along a headwater stream with a wider riparian buffer (similar to 15 m) and moderate upslope thinning; and 3) along a headwater stream with an unthinned upslope. Streamside and upslope maximum air temperatures measured during July 2006 along all three streams were near or exceeded 30 degrees C, the critical thermal tolerance threshold for western plethodontid salamanders. Streamside and upslope temperatures inside small logs, large logs and soils stayed below critical temperatures. Our results suggest that logs of a wide size range, as well as soils, may provide sufficient protection against thermal extremes in uncut forests and thinned stands with limited overstory.

TI Characteristics of Summer and Fall Diurnal Resting Habitat Used by
American Martens in Coastal Northwestern California
SO NORTHWEST SCIENCE
LA English
DT Article
ID SELECTION
AB American martens use resting habitat between periods of activity to provide both thermal refugia and protection from predators. Maintenance or restoration of key elements of marten resting habitat, such as resting structures, requires that managers recognize their characteristics to protect them. or manage for their creation. We measured resting habitat at 4 scales: (1) the resting location-where the marten actually rested (2) the resting structure-the habitat element that contained the resting location: (3) the resting site-characteristics in the immediate vicinity of each resting structure; and (4) the resting stand-the forest stand containing the resting structure. During the summer and fall of 2001 and 2002 we identified resting structures used by 12 radio-collared martens (7 Male, 5 Female) and I uncollared marten. The animals were the members of the only remnant population of martens within the historical range of the Humboldt marten (M. a. humboldtensis). The study area included portions of the Six Rivers National Forest, Smith River National Recreation Area, and adjacent Green Diamond Resource Company lands in coastal northwestern California. We located martens resting on 55 occasions in the following types of structures: snags (37%), logs (23%), live-trees (17%), slash-piles (10%), rock-piles (8%), and shrub clumps (6%). The location in the structure where the marten actually rested was determined on 92% of occasions and included chambers (33%), cavities (33%), broken tops (22%), branch platforms (6%). ground sites (6%), and basal hollows (2%). Woody structures were large. with mean dbh of 93.9 cm for live-trees, 94.9 cm for snags, and 88.2 cm maximum-diameter for logs. The mean age of 24 of the woody resting structures was 339 year, (range 13 1666 years). Our results are consistent with results from other studies on resting structure use and highlight the importance of large live and dead woody structures for American martens in coastal forests of northwestern California.

AB A widespread and intense spruce beetle outbreak during the 1990s has killed most of the mature white spruce (Picea glauca) trees across many watersheds in south-central Alaska. To investigate the potential habitat impacts in a salmon stream, we characterized the current abundance and species composition of large woody debris (LWD). examined the linkages between LWD and salmonid habitat, and estimated changes in LWD abundance and associated pool habitat over time. LWD abundance was relatively low (97 pieces/km overall) and varied widely according to riparian vegetation typology, ranging from 15 pieces/km at sites with non-forested riparian zones to 170 pieces/km at sites adjacent to cottonwood forest. LWD provided significant fish cover in pools, especially in cottonwood forest stream reaches. LWD-formed pools were relatively rare (15% of total), but LWD abundance explained much of the variation in pool frequency (r(2) = 0.86 in spruce forest reaches) and in the proportion of pool habitats (r(2) = 0.85 in cottonwood forest reaches). We project the spruce beetle outbreak to result in a substantial net increase in LWD abundance over a 50-year span, peaking with 243% and 179% increases in LWD abundance for spruce forest and cottonwood forest stream reaches. respectively. in the year 2025. Concurrent with the peak in LWD abundance, our estimates show pool frequency in spruce forest reaches to reach 207% of current levels and the proportion of pools in cottonwood forest reaches to reach 167% of current levels. changes that correspond with substantially increased potential habitat for juvenile salmonids.

AB The gastrointestinal tract (GIT) is a metabolically significant site of sulfur amino acid (SAA) metabolism in the body and metabolises about 20 % of the dietary methionine intake which is mainly transmethylated to homocysteine and trans-sulfurated to cysteine. The GIT accounts for about 25 % of the whole-body transmethylation and trans-sulfuration. In addition, in vivo studies in young pigs indicate that the GIT is a site of net homocysteine release and thus may contribute to the homocysteinaemia. The gut also utilises 25 % of the dietary cysteine intake and the cysteine uptake by the gut represents about 65 % of the splanchnic first-pass uptake. Moreover, we recently showed that SAA deficiency significantly suppresses intestinal mucosal growth and reduces intestinal epithelial cell proliferation, and increases intestinal oxidant stress in piglets. These recent findings indicate that intestinal metabolism of dietary methionine and cysteine is nutritionally important for intestinal mucosal growth. Besides their role in protein synthesis, methionine and cysteine are precursors of important molecules. S-adenosylmethionine, a metabolite of methionine, is the principal biological methyl donor in mammalian cells and a precursor for polyamine synthesis. Cysteine is the rate-limiting amino acid for glutathione synthesis, the major cellular antioxidant in mammals. Further studies are warranted to establish how SAA metabolism regulates gut growth and intestinal function, and contributes to the development of gastrointestinal diseases. The present review discusses the evidence of SAA metabolism in the GIT and its functional and nutritional importance in gut function and diseases.

In addition, they contain more than 20 unique polyphenols, avenanthramides, which have shown strong antioxidant activity in vitro and in vivo. The polyphenols of oats have also recently been shown to exhibit anti-inflammatory, antiproliferative, and anti-itching activity, which may provide additional protection against coronary heart disease, colon cancer, and skin irritation.

AB Obesity is highly prevalent in African Americans and is associated with increased risk of End-Stage Renal Disease (ESRD) and death. It is not known if the effect of obesity is similar among blacks and whites. The aim of this study is to examine racial differences in the association of obesity with ESRD and survival in elderly patients (age > 65). Data were obtained for 74,167 Medicare patients with acute myocardial infarction (AMI) between February 1994 and July 1995. BMI was calculated as weight (kg) divided by height (m(2)). We evaluated the association of BMI class with ESRD incidence and death using multivariable Cox proportional hazards models, testing for race-BMI interactions. Compared to whites, African Americans had higher BMI (26.9 vs. 26.0, P < 0.0001) and estimated glomerular filtration rate (72.4 ml/min/1.73 m(2) vs. 66.6 ml/min/1.73 m(2), P < 0.0001). Crude ESRD rates increased with increasing obesity among whites but not among blacks. However, after adjusting for age, sex, and other comorbidities, obesity was not associated with increased ESRD rate among blacks or whites and the interaction between race and BMI was not significant. Furthermore, for both races, patients classified as overweight, class 1 obese, or class 2 obese had similar, significantly better survival abilities compared to normal weight patients and the race BMI interaction was not significant. In conclusion, obesity does not increase risk of ESRD among black or white elderly subjects with cardiovascular disease (CVD). However, both obese blacks and whites, in this population, experience a survival benefit. Further studies need to explore this obesity paradox.

The present results clearly indicate that small linear synthetic peptides can penetrate the cuticle very efficiently by contact application and activate their target organ. The time responses of the peptides applied in DDW and DMSO were tested and the activities of topically applied and injected peptides were compared. The results clearly indicate that PK-beta A-4 and PK-beta A-3 exhibited high bioavailability (ability to penetrate through the cuticle and exertion of bioactivity) with the latter showing longer persistence in both solvents than any other analog in the study; indicative that incorporation of a beta-amino acid at the Phe(2) position can enhance longevity in topical PK/PBAN analogs. PK-beta A-4 was significantly more active in DMSO than in DDW, and significantly more active than the parent peptide LPK in DMSO. PK-beta A-1 and PK-beta A-2 exhibited negligible activity. Interestingly, Ac-YFTPRLa was highly potent in both solvents; its activity in DDW did not differ from that of PK-beta A-4 and PK-beta A-3, and was higher than that of LPK Even the unacylated peptide YFTPRLa was active in both solvents, at a similar level to LPK. Topically applied PK-beta A-4 and Ac-YFTPRLa exhibited significantly higher activity than the injected peptides. PK-beta A-3 and YFTPRLa were equally potent in both routes of administration.

Modern zoological gardens are institutions to wildlife maintenance, aiming its conservation, the performance of scientific research and leisure, recreation and environmental education activities. The variety of wild species living in conditions different from the one found in its natural habitats represents a propitious environment for diseases spread, specially the zoonotic ones. Due to data shortage and wild mammals' epidemiological relevance both for toxoplasmosis as for leptospirosis, this study aimed to determine the serological survey of toxoplasmosis and leptospirosis in Neotropical wild mammals, from Zoo of Aracaju, Sergipe, Brazil. Blood samples were collected from 32 wild mammals, adults and from both sexes: 14 wild bearded capuchins (Cebus libidinosus), four golden-bellied capuchins (Cebus xanthosternus), three pumas (Puma concolor), one jaguar (Panthera onca), one crab-eating fox (Cerdocyon thous), six crab-eating raccoons (Procyon cancrivorus), two South American coatis (Nasua nasua), and one tayra (Eira barbara). Sera were tested to Toxoplasma gondii antibodies by the modified agglutination test (MAT e"1:25), and by the microscopic seroaglutination test (cut-off e"1: 100) using 24 serovar of pathogenic leptospiras and two serovar of saprophyte leptospiras. Antibodies to T. gondii were found in 17 of 32 (53.1%) wild mammals, and antibodies to Leptospira spp. were found in 4 of 32 (12.5%) wild mammals. In relation to gender, 9 of 15 (60%) males, and 8 of 17 (47.1%) females had antibodies to Toxoplasma gondii, and 4 of 15 (26.7%) males had antibodies to Leptospira spp. Considering the origin of the seropositive animals to T. gondii, 8 of 17 (47%) were born in the zoo, 7 of 17 (41.2%) were from other zoos, and 2 (11.8%) were from the wild. Three of 4 (75%) mammals seropositive to Leptospira spp. were born in zoo, and 1 of 4 (25%) was from the wild. This is the first serological survey of Leptospira spp. in Neotropical primates and carnivores from Northeast zoo of Brazil, and the first time that antibodies to T. gondii and Leptospira spp. (serovar Copenhageni) were observed in the threaten specie of primate golden-bellied capuchins (Cebus xanthosternus) in Aracaju, SE.

AB Fifty years ago, Stern, Smith, van den Bosch and Hagen outlined a simple but sophisticated idea of pest control predicated on the complementary action of chemical and biological control. This integrated control concept has since been a driving force and conceptual foundation for all integrated pest management (IPM) programs. The four basic elements include thresholds for determining the need for control, sampling to determine critical densities, understanding and conserving the biological control capacity in the system and the use of selective insecticides or selective application methods, when needed, to augment biological control. Here we detail the development, evolution, validation and implementation of an integrated control (IQ program for whitefly, Bemisia tabaci (Genn.), in the Arizona cotton system that provides a rare example of the vision of Stern and his colleagues. Economic thresholds derived from research-based economic injury levels were developed and integrated with rapid and accurate sampling plans into validated decision tools widely adopted by consultants and growers. Extensive research that measured the interplay among pest population dynamics, biological control by indigenous natural enemies and selective insecticides using community ordination methods, predator: prey ratios, predator exclusion and demography validated the critical complementary roles played by chemical and biological control. The term 'bioresidual' was coined to describe the extended environmental resistance from biological control and other forces possible when selective insecticides are deployed. The tangible benefits have been a 70% reduction in foliar insecticides, a >$200 million saving in control costs and yield, along with enhanced utilization of ecosystem services over the last 14 years.

AB The seminal work of Stern and his coauthors on integrated control has had a profound and long-lasting effect on the development of IPM programs in western orchard systems. Management systems based solely on pesticides have proven to be unstable, and the success of IPM systems in western orchards has been driven by conservation of natural enemies to control secondary pests, combined with pesticides and mating disruption to suppress the key lepidopteran pests. However, the legislatively mandated changes in pesticide use patterns prompted by the Food Quality Protection Act of 1996 have resulted in an increased instability of pest populations in orchards because of natural enemy destruction. The management system changes have made it necessary to focus efforts on enhancing biological control not only of secondary pests but also of primary lepidopteran pests to help augment new pesticides and mating disruption tactics. The new management programs envisioned will be information extensive as well as time sensitive and will require redesign of educational and outreach programs to be successful. The developing programs will continue to use the core principles of Stern and his co-authors, but go beyond them to incorporate changes in society, technology and information transfer, as needed.

AB In the 'Integrated Control Concept', Stern et al. emphasized that, although insecticides are necessary for agricultural production, they should only be used as a last resort and as a complement to biological control. They argued that selective insecticide use should only be attempted after it has been determined that insect control with naturally occurring biotic agents is not capable of preventing economic damage. However, they concluded their seminal paper by emphasizing that integrated control will not work where natural enemies are inadequate or where economic thresholds are too low to rely on biological control. Thus, it is no surprise that insect control in high-value, fresh-market lettuce crops grown in the desert southwest have relied almost exclusively on insecticides to control a complex of mobile, polyphagous pests. Because lettuce and leafy greens are short-season annual crops with little or no tolerance for insect damage or contamination, biological control is generally considered unacceptable. High expectations from consumers for aesthetically appealing produce free of pesticide residues further forces vegetable growers to use chemical control tactics that are not only effective but safe. Consequently, scientists have been developing integrated pest management (IPM) programs for lettuce that are aimed at reducing the economic, occupational and dietary risks associated with chemical controls of the past. Most of these programs have drawn upon the integrated control concept and promote the importance of understanding the agroecosystem, and the need to sample for pest status and use action thresholds for cost-effective insect control. More recently, pest management programs have implemented newly developed, reduced-risk chemistries that are selectively efficacious against key pests. This paper discusses the influence that the integrated control concept, relative to zero-tolerance market standards and other constraints, has had on the adoption of pest management in desert lettuce crops.

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

AB 2-DE analysis of complex plant proteomes has limited dynamic resolution because only abundant proteins can be detected. Proteomic assessment of the low abundance proteins within leaf tissue is difficult when it is comprised of 30-50% of the CO2 fixation enzyme Rubisco. Resolution can be improved through depletion of Rubisco using fractionation techniques based upon different physiological or biochemical principles. We have developed a fast and simple fractionation technique using 10 mM Ca2+ and 10 mM phytate to precipitate Rubisco from soybean leaf soluble protein extract. This method is not only rapid, but also inexpensive, and capable of removing 85% of the extremely abundant Rubisco enzyme from soybean leaf soluble protein extract. This method allowed for roughly 230 previously inconspicuous protein spots in soybean leaf to be more easily detectable (3-fold increase in vol%) using fluorescent detection and allowed 28 phosphorylated proteins previously undetected, to be isolated and identified by MALDI-TOF-MS.

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

Asiatic citrus canker is an economically significant disease of citrus caused by the bacterial plant pathogen Xanthomonas citri subsp. citri. The pathogen is a major exotic disease problem in many citrus producing areas of the world including the United States, Brazil, and Australia. Various eradication attempts have been made on the disease but have been associated with significant social and economic costs due to the necessary removal of large numbers of host trees. In this paper, a spatially explicit stochastic simulation model of Asiatic citrus canker is introduced that describes an epidemic of the disease in a heterogeneous host landscape. We show that an optimum eradication strategy can be determined that minimizes the adverse costs associated with eradication. In particular, we show how the optimum strategy and its total cost depend on the topological arrangement of the host landscape. We discuss the implications of the results for invading plant disease epidemics in general and for historical and future eradication attempts on Asiatic citrus canker.

AB Grapevine fanleaf virus (GFLV) was documented in self-rooted vines of four grapevine (Vitis vinifera) cultivars in eastern Washington. GFLV was found as mixed infection in cvs. Pinot Noir, Chardonnay, and Cabernet Franc and as single infections in cv. Merlot. Fanleaf disease symptoms were only observed in the first two cultivars. The spatial distribution of GFLV-infected grapevines was random, suggesting primary spread through planting virus-infected cuttings rather than infield transmission. RNA1 sequences of Washington isolates showed 87 to 89% nucleotide sequence identity between them and with strain F13. RNA2 of Washington isolates was variable in size, showing 85 to 99% sequence identity between them and 81 to 92% with other isolates. As in other GFLV isolates, three conserved putative stem-loop structures were present in the 5' noncoding regions of both RNAs of Washington isolates. Phylogenetic incongruence of GFLV isolates from Washington in 2A(HP)- and 2B(MP)-based trees and identification of putative recombination events suggested that their genomic RNA2 originated from inter-and intraspecies recombination events between GFLV, Grapevine deformation virus, and Arabis mosaic virus. These results confirm interspecies recombination in RNA2 of grapevine-infecting nepoviruses as an important strategy for GFLV evolution.

AB Understanding the metabolic responses of the plant to a devastating foliar disease, soybean rust, caused by Phakopsora pachyrhizi, will assist in development of cultivars resistant to soybean rust. In this study, differences in phenolic metabolism were analyzed between inoculated and noninoculated plants using two susceptible and three resistant soybean genotypes with known resistance genes. Rust infection resulted in increased accumulation of isoflavonoids and flavonoids in leaves of all soybean genotypes tested. Although the soybean phytoalexin glyceollin was not detected in leaves of uninfected plants, accumulation of this compound at marked levels occurred in rust-infected leaves, being substantially higher in genotypes with a red-brown resistant reaction. In addition, there was inhibition of P. pachyrhizi spore germination by glyceollin, formononetin, quercetin, and kaempferol. However, there was no correlation between concentrations of flavonoids quercetin and kaempferol and rust-induced isoflavonoid formononetin in soybean leaves and rust resistance. Lignin synthesis also increased in all inoculated soybean genotypes whereas there was no significant difference in all noninoculated soybean genotypes. Cell wall lignification was markedly higher in inoculated resistant lines compared with inoculated susceptible lines, indicating a possible protective role of lignin in rust infection development.

AB A series of laboratory tests were conducted to investigate potential effects of fungus gnat (Bradysia impatiens) feeding damage on susceptibility of geranium seedlings (Pelargonium x hortorum) to infection by the root rot pathogen Pythium aphanidermatum. Effects were compared with those from similar tests in which the seedlings were mechanically wounded by severing the root tip with a scalpel. Assays of geranium seedlings in petri dishes revealed a pronounced negative fungus gnat-Pythium interaction, with exposure to fungus gnat larvae 24 h prior to inoculation with P. aphanidermatum zoospores resulting in up to 47% fewer seedling deaths than would have been expected if the two agents had acted independently. Similar results were observed when seedlings were subjected to mechanical wounding 24 h prior to zoospore inoculation. In contrast, no interaction occurred when seedlings were mechanically wounded immediately prior to inoculation. The degree of plant damage inflicted by the feeding activities of the larval fungus gnats had no significant effect on the combined damage from fungus gnats and Pythium in petri dishes. Ancillary studies showed that Pythium development on V8 agar was not inhibited by the presence of fungus gnat-associated microorganisms, nor were seedlings inoculated with these microbes less susceptible to Pythium infection. The precise mechaism or mechanisms underlying the observed interactions were not elucidated; however, the results strongly suggest that both fungus gnat feeding and mechanical wounding activated systemic defenses that made the seedlings more resistant to Pythium infection.

AB P>Biotechnologists seeking to limit gene expression to nonseed tissues of genetically engineered cereal crops have only a few choices of well characterized organ-specific promoters. We have isolated and characterized the promoter of the rice Leaf Panicle 2 gene (LP2, Os02g40240). The LP2 gene encodes a leucine-rich repeat-receptor kinase-like protein that is strongly expressed in leaves and other photosynthetic tissues. Transgenic rice plants containing an LP2 promoter-GUS::GFP bifunctional reporter gene displayed an organ-specific pattern of expression. This expression corresponded to transcript levels observed on RNA blots of various rice organs and microarray gene expression data. The strongest beta-glucuronidase activity was observed in histochemically stained mesophyll cells, but other green tissues and leaf cell types including epidermal cells also exhibited expression. Low or undetectable levels of LP2 transcript and LP2-mediated reporter gene expression were observed in roots, mature seeds, and reproductive tissues. The LP2 promoter is highly responsive to light and only weak expression was detected in etiolated rice seedlings. The specificity and strength of the LP2 promoter suggests that this promoter will be a useful control element for green tissue-specific expression in rice and potentially other plants. Organ-specific promoters like LP2 will enable precise, localized expression of transgenes in biotechnology-derived crops and limit the potential of unintended impacts on plant physiology and the environment.

AB P>Straighthead is a physiological disorder in rice (Oryza sativa L.) resulting in sterile florets, poorly developed panicles and yield loss. Because of its sporadic nature and unidentified causes for the disorder, molecular marker assisted selection is essential for resistance improvement in breeding programmes. To take advantage of recent advances in gene-mapping technology, we executed a genome-wide association mapping to identify genetic regions associated with straighthead disorder using 547 accessions of germplasm from the USDA rice core collection. Straighthead was evaluated in arsenic treated soil and genotyping was conducted with 75 molecular markers covering the entire rice genome about every 25 cM. A mixed-linear model approach combining the principal component assignments with kinship estimates proved to be particularly promising for association mapping. The extent of linkage disequilibrium was described among the markers. Six markers were found to be significantly associated with straighthead, explaining 35% of the total phenotypic variation. However, only two SSR markers, RM413 and RM277 on chromosome 5 and 12, respectively, have a significant association with low rating indicating straighthead resistance. Confirmation of the marker-straighthead association using segregating populations is necessary before marker-assisted selection can be applied.

AB The objective of this study was to determine the Vrn-1 allelic composition of spring wheat germplasm from the Pacific Northwest region of the USA. Individual plants from 56 spring wheat lines were crossed to near-isogenic tester lines carrying the dominant allele Vrn-A1, Vrn-B1 or Vrn-D1. F(2) progeny were evaluated for growth habit in the field and Vrn-1 allelic composition was determined through chi-square analysis. Lines also were analysed with DNA sequence-based Vrn-1 allele-specific markers. A majority of the germplasm carried the dominant allele Vrn-A1a alone or in combination with Vrn-B1, Vrn-D1 or Vrn-B3 alleles. Vrn-B1 and Vrn-D1 were almost always associated with other dominant Vrn-1 allele(s). Based on DNA sequence analysis, a novel Vrn-B1 allele referred to as Vrn-B1b, which carried a single nucleotide polymorphism (SNP) and a 36 bp deletion, was identified in cultivar 'Alpowa'. These results will be useful to wheat breeders for choosing parents with different Vrn-1 alleles for crossing to maximize diversity at the Vrn-1 loci with an expectation of identifying superior Vrn-1 allelic combinations for cultivar improvement.

AB Yellow dwarf (YD) disease is one of the most destructive diseases of cereals worldwide. Wheat (Triticum aestivum L.)-Thinopyrum intermedium 7E(7D) substitution line P29 carries resistance to YD, known as Bdv3, that originates on the long arm of chromosome 7E of Th. intermedium, and the resistance was introgressed into wheat chromosome 7D as T7DS.7DL-7EL in the translocation lines P961341 and P98134. Until now, quantification of YD viruses in cereal crops was usually done by enzyme-linked immunosorbent assay (ELISA), which is time consuming and laborious. To facilitate this analysis, SSR-Bdv3, a diagnostic molecular marker, was developed in this study. The transmission of the Th. intermedium segment with Bdv3 was investigated using the SSR-Bdv3 marker and ELISA in F(2) and testcross progeny derived by crossing two wheat-Th. intermedium translocation lines to four common wheat cultivars. A Th. intermedium chromosome 7E segment in the translocation line P98134 was preferentially transmitted through male gametes in all of its crosses with the four wheat cultivars. However, the transmission frequency of the Th. intermedium 7E segment in another wheat-Th. intermedium translocation line, P961341, varied in different genetic backgrounds. The F(2) populations from reciprocal crosses of Chinese Spring and P961341 showed good fits to the expected ratio of 1 : 2 : 1. In this study, male preferential transmission for either chromosome 7E or chromosome 7D was observed in the progeny derived by crossing P961341 to other wheat cultivars.

AB A sunflower (Helianthus annuus L.) mutant was observed in the progeny of a cross between the sunflower cultivar 'HA 89' and an amphiploid of a Helianthus divaricatus L. x P21 cross that exhibited loss of dormancy induction in the developing embryo. Seeds of this mutant frequently germinate on the head about 40 days after pollination. The cotyledons of this mutant remain green, whereas some other non-dormant mutants exhibit loss of pigmentation. The objectives of this investigation were to compare levels and activities of abscisic acid (ABA), a plant hormone that induces dormancy in developing embryos, in the non-dormant green mutant (NDG) and 'HA 89' from which NDG was derived. Immunoassays showed that abscisic acid was present in NDG and the levels were not significantly different from those in 'HA 89'. Exposure of excised NDG mutant embryos to 40 mu m abscisic acid failed to prevent germination, suggesting that non-dormancy could result from impairment in ABA receptors or from a defect in other proteins participating in the subsequent signalling pathway that normally induces dormancy.

AB Poor adventitious root formation is a major obstacle in micropropagation. In this study, intense efforts have been made for improvement of rooting procedures for triploid, tetraploid and mixploid clones of the pear cultivar 'Fertility' obtained by in vitro colchicine treatment. An efficient rooting procedure has been developed for the pear clones of different ploidy by adding polyvinyl alcohol (PVA) to the rooting medium. PVA significantly improved rooting percentage and root number per plantlet for diploid, triploid and tetraploid clones. However, PVA had little or no effect on rooting capacity of mixploid clones. The efficiency of in vitro rooting in diploid, triploid, tetraploid and mixploid is highly genotype-dependent. In general, diploid was the highest, followed by triploid and tetraploid, mixploid was the lowest.

AB Puccinia horiana, the causal agent of chrysanthemum while rust, is a pathogen of quarantine status in Many Countries where Chrysanthemum x morifolium cultivars are grown. Historically, identification protocols for white rust relied upon macroscopic symptom development and microscopic examination of infected leaves for tehospores. Symptoms become visible 7 to 10 days after Initial infection under favorable conditions followed by the production of teha. Infected plants can therefore evade detection before symptoms and fruiting bodies ire evident Conventional and real-time polymerase chain reaction (PCR) assays were developed to detect P. horiana using primers designed to amplify portions of the Internal transcribed spacer (ITS) regions of the nuclear ribosomal DNA (rDNA) The species-specific primers, could defect the pathogen front I ng of DNA isolated from infected leaf tissue in conventional PCR assays and from 1 pg in real-time PCR assays. While both assays were capable of delecting P horiana in symptomatic tissue, the greater sensitivity offered by the real-time PCR assay makes it more reliable for detecting the pathogen during the latent stage of infection. The R horiana printers did not amplify the rDNA target using DNA isolated from leaf tissue infected with P. chrysanthemum

AB P>The stem cells of the vascular cambium divide to produce daughter cells, which in turn divide before undergoing differentiation during the radial growth of woody stems. The genetic regulation of these developmental events is poorly understood, however. We report here the cloning and functional characterization of a Populus class-I KNOX homeobox gene, ARBORKNOX2 (ARK2), which we show influences terminal cell differentiation and cell wall properties during secondary growth. In the early stages of secondary growth, ARK2 is expressed broadly in the cambial zone and in terminally differentiating cell types, before becoming progressively restricted to the cambium. ARK2 overexpression and synthetic miRNA-suppression transgenics reveal positive correlations between ARK2 expression level and the timing of cambium formation, the width of the cambial zone and inhibition of cambial daughter cell differentiation. These phenotypes in turn correlate with changes in the expression of genes affecting transcription, cell division, auxin and cell wall synthesis. Notably, wood properties associated with secondary cell wall synthesis are negatively associated with ARK2 expression, including lignin and cellulose content. Together, our results suggest that ARK2 functions primarily to regulate a complex suite of genes that together influence cell differentiation during secondary growth. We propose that ARK2 may represent a co-evolved transcriptional module that influences complex, adaptive wood properties.

AB The syncytium is a nurse cell formed within the roots of Glycine max by the plant parasitic nematode Heterodera glycines. Its development and maintenance are essential for nematode survival. The syncytium appears to undergo two developmental phases during its maturation into a functional nurse cell. The first phase is a parasitism phase where the nematode establishes the molecular circuitry that during the second phase ensures a compatible interaction with the plant cell. The cytological features of syncytia undergoing susceptible or resistant reactions appear the same during the parasitism phase. Depending on the outcome of any defense response, the second phase is a period of syncytium maintenance (susceptible reaction) or failure (resistant reaction). In the analyses presented here, the localized gene expression occurring at the syncytium during the resistant reaction was studied. This was accomplished by isolating syncytial cells from Glycine max genotype Peking (PI 548402) by laser capture microdissection. Microarray analyses using the Affymetrix(A (R)) soybean GeneChip(A (R)) directly compared Peking syncytia undergoing a resistant reaction to those undergoing a susceptible reaction during the parasitism phase of the resistant reaction. Those analyses revealed lipoxygenase-9 and lipoxygenase-4 as the most highly induced genes in the resistant reaction. The analysis also identified induced levels of components of the phenylpropanoid pathway. These genes included phenylalanine ammonia lyase, chalcone isomerase, isoflavone reductase, cinnamoyl-CoA reductase and caffeic acid O-methyltransferase. The presence of induced levels of these genes implies the importance of jasmonic acid and phenylpropanoid signaling pathways locally at the site of the syncytium during the resistance phase of the resistant reaction. The analysis also identified highly induced levels of four S-adenosylmethionine synthetase genes, the EARLY-RESPONSIVE TO DEHYDRATION 2 gene and the 14-3-3 gene known as GENERAL REGULATORY FACTOR 2. Subsequent analyses studied microdissected syncytial cells at 3, 6 and 9 days post infection (dpi) during the course of the resistant reaction, resulting in the identification of signature gene expression profiles at each time point in a single G. max genotype, Peking.

AB Downy mildew of hop, caused by Pseudoperonospora humuli, is an important disease in most regions of hop production and is managed largely with regular fungicide applications. A PCR assay specific to P. humuli and the related organism P. cubensis was developed and used to monitor airborne inoculum in hop yards to initiate fungicide applications. The PCR amplified as little as 1 fg of genomic DNA of P. humuli, and yielded an amplicon in 70% of reactions when DNA was extracted from single sporangia. In the presence of 25 mg of soil, an amplicon was amplified in 90% of reactions when DNA was extracted from 10 or more sporangia. During nine location-years of validation, PCR detection of the pathogen in air samples occurred no later than 8 days after the appearance of trace levels of disease signs and/or detection of airborne spores in a volumetric spore sampler. Inoculum was detected on average 4 center dot 5 days before (range -8 to 14 days) the first appearance of basal spikes in six commercial yards, or 1 center dot 3 days after (range -5 to 1 days) sporangia were detected in a volumetric spore sampler in experimental plots. In commercial yards, use of PCR to initiate the first fungicide application led to enhanced disease control or a reduction in fungicide use in four of six yards compared to growers' standard practices. These results indicate that the efficiency and efficacy of hop downy mildew management can be improved when control measures are timed according to first detection of inoculum.

AB The collective impact of several environmental factors on the biocontrol activity of Trichoderma stromaticum (Ts) against Moniliophthora perniciosa (Mp), the cause of cacao witches' broom disease, was assessed under field conditions of shaded cacao (Theobroma cacao) in south-eastern Bahia, Brazil. Biocontrol experiments were performed adjacent to an automated weather station, with sensors and Ts-treated brooms placed at different canopy heights. Sporulation occurred at the same dates for all Ts isolates, but in different quantities. Broom moisture > 30%, air temperature of approximately 23 +/- 3 degrees C, relative humidity > 90%, solar radiation intensities < 0 center dot 12 KW m-superset of and wind speed near zero were the key environmental parameters that preceded Ts sporulation events. A multiple logistic regression indicated that these weather variables combined were capable of distinguishing sporulation from non-sporulation events, with a significant effect of wind speed. Analyses of environmental factors at ground level indicated similar pre-sporulation conditions, with a soil moisture content above a threshold of 0 center dot 34 m3 m-3 preceding all sporulation events. The sporulation of five selected Ts isolates was compared at four different canopy heights. Isolates responded differently to weather variation in terms of sporulation and antagonism to Mp at different canopy levels, indicating that different microclimates are established along the vertical profile of a shaded cacao plantation. The potential of these findings for development of predictive mathematical models and disease-management approaches is discussed.

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

AB The information and resources generated from diverse "omics" technologies provide opportunities for producing novel biological knowledge. It is essential to integrate various kinds of biological information and large-scale omics data sets through systematic analysis in order to describe and understand complex biological phenomena. For this purpose, we have developed a Web-based system, Plant MetGenMAP, which can comprehensively integrate and analyze large-scale gene expression and metabolite profile data sets along with diverse biological information. Using this system, significantly altered biochemical pathways and biological processes under given conditions can be retrieved rapidly and efficiently, and transcriptional events and/or metabolic changes in a pathway can be easily visualized. In addition, the system provides a unique function that can identify candidate promoter motifs associated with the regulation of specific biochemical pathways. We demonstrate the functions and application of the system using data sets from Arabidopsis (Arabidopsis thaliana) and tomato (Solanum lycopersicum), respectively. The results obtained by Plant MetGenMAP can aid in a better understanding of the mechanisms that underlie interesting biological phenomena and provide novel insights into the biochemical changes associated with them at the gene and metabolite levels. Plant MetGenMAP is freely available at http://bioinfo.bti.cornell.edu/tool/MetGenMAP.

AB Maize (Zea mays) leaves provide a useful system to study how proximal/distal patterning is established because of the distinct tissues found in the distal blade and the proximal sheath. Several mutants disrupt this pattern, including the dominant knotted1-like homeobox (knox) mutants. knox genes encode homeodomain proteins of the TALE superclass of transcription factors. Class I knox genes are expressed in the meristem and down-regulated as leaves initiate. Gain-of-function phenotypes result from misexpression in leaves. We identified a new dominant allele of maize knotted1, Kn1-DL, which contains a transposon insertion in the promoter in addition to a tandem duplication of the kn1 locus. In situ hybridization shows that kn1 is misexpressed in two different parts of the blade that correlate with the different phenotypes observed. When kn1 is misexpressed along the margins, flaps of sheath-like tissue form along the margins. Expression in the distal tip leads to premature termination of the midrib into a knot and leaf bifurcation. The gain-of-function phenotypes suggest that kn1 establishes proximal/distal patterning when expressed in distal locations and lead to the hypothesis that kn1 normally participates in the establishment of proximal/distal polarity in the incipient leaf.

AB Root exudates influence the surrounding soil microbial community, and recent evidence demonstrates the involvement of ATP-binding cassette (ABC) transporters in root secretion of phytochemicals. In this study, we examined effects of seven Arabidopsis (Arabidopsis thaliana) ABC transporter mutants on the microbial community in native soils. After two generations, only the Arabidopsis abcg30 (Atpdr2) mutant had significantly altered both the fungal and bacterial communities compared with the wild type using automated ribosomal intergenic spacer analysis. Similarly, root exudate profiles differed between the mutants; however, the largest variance from the wild type (Columbia-0) was observed in abcg30, which showed increased phenolics and decreased sugars. In support of this biochemical observation, whole-genome expression analyses of abcg30 roots revealed that some genes involved in biosynthesis and transport of secondary metabolites were up-regulated, while some sugar transporters were down-regulated compared with genome expression in wild-type roots. Microbial taxa associated with Columbia-0 and abcg30 cultured soils determined by pyrosequencing revealed that exudates from abcg30 cultivated a microbial community with a relatively greater abundance of potentially beneficial bacteria (i.e. plant-growth-promoting rhizobacteria and nitrogen fixers) and were specifically enriched in bacteria involved in heavy metal remediation. In summary, we report how a single gene mutation from a functional plant mutant influences the surrounding community of soil organisms, showing that genes are not only important for intrinsic plant physiology but also for the interactions with the surrounding community of organisms as well.

AB The germin protein family is comprised of two main subgroups in plants, oxalate oxidases (OXOs) and germin-like proteins (GLPs). These proteins are implicated in a variety of plant processes including germination, development, pollen formation, and response to abiotic and biotic stress Here, we examine the phylogenetic relationships and functional diversity of the germin gene family across diverse genera. and then focus on rice (Oryza sativa) as a model In general, germin genes are expressed in all tissue types and are induced by biotic and/or abiotic stresses In rice, many of the stress-induced germin genes physically co-localize with quantitative trait loci (QTL) for disease resistance, and emerging evidence suggests that small RNAs may regulate their transcript abundance. We analyze the extensive sequence, gene expression and functional data for germin family proteins and relate them to QTL map locations to predict additional candidate germin genes for future crop improvement.

AB The earth is rapidly changing through processes such as rising [CO(2)], [O(3)], and increased food demand. By 2050 the projected atmospheric [CO(2)] and ground level [O(3)] will be 50% and 20% higher than today. To meet future agricultural demand, amplified by an increasing population and economic progress in developing countries. crop yields will have to increase by at least 50% by the middle of the century. FACE (Free Air Concentration Enrichment) experiments have been conducted for more than 20 years in various parts of world to estimate. under the most realistic agricultural conditions possible, the impact of the CO(2) levels projected for the middle of this century on crops. The stimulations of crop seed yields by the projected CO(2) levels across FACE studies are about 18% on average and up to similar to 30% for the hybrid rice varieties and vary among crops, cultivars, nitrogen levels and soil moisture The observed increase in crop yields under the projected CO(2) levels fall short of what would be required to meet the projected future food demand, even with the most responsive varieties. Crop biomass production and seed yield is the product of photosynthetic solar energy conversion. Improvement in photosynthetic radiation use efficiency stands as the most promising opportunity allowing for major increases in crop yield in a future that portends major changes in climate and crop growing environments. Our advanced understanding of the photosynthetic process along with rapidly advancing capabilities in functional genomics, genetic transformation and synthetic biology promises new opportunities for crop improvement by greater photosynthesis and crop yield Traits and genes that show promise for improving photosynthesis are briefly reviewed, including enhancing leaf photosynthesis capacity and reducing photorespiratron loss, manipulating plant hormones' responses for better ideotypes, extend: rig duration of photosynthesis, and increasing carbon partitioning to the sink to alleviate feedback inhibition of photosynthesis (C) 2009 Elsevier Ireland Ltd All rights reserved

AB In 1960, Chouard hypothesized that there might be a connection between vernalization (facilitation of floral competence) and release from endodormancy. In 2003 we reiterated this hypothesis and suggested potential mechanisms involving chromatin remodeling. Since then, there have been several papers from various laboratories working on several different perennial species that suggest common signaling components regulate flowering and the growth cessation that must precede endodormancy induction. This work has directly implicated FT, CENL1, and MADE-box transcription factor genes similar to SVP and/or AGL24 in growth cessation and endodormancy development. Numerous studies in other model systems have demonstrated the function and regulation of similar genes in floral regulation. Combined, these studies allow the development of a paradigm for future investigations designed to understand the nature and function of the regulatory mechanisms that control Induction and release of endodormancy in perennial plants. Dicots, monocots, and gymnosperms have similar floral regulatory genes, suggesting that general regulation of flowering is highly conserved among perennial species. Likewise, reports of differential expression of particular MADS-box genes and putative FT orthologues during endodormancy transitions across multiple plant species suggest a conserved role for these genes in responses to endodormancy induction and maintenance. The limited but tantalizing linkage between floral regulatory machinery and seasonal growth cessation and bud set through regulation of FT and other FT-like genes suggest a general model for endodormancy regulation.

AB Leaves of overwintering evergreen rhododendrons are typically exposed to freezing temperatures and high light during winters which can potentially result in photon flux exceeding that required for photochemistry. This excess energy. if not dissipated as heat or fluorescence, may cause photooxidative damage to PSII. The goal of this study is to compare the photoprotection strategies during seasonal cold acclimation (CA) in two Rhododendron species (R. catawbiense Michx. and R. ponticum L) that are divergent in their leaf freezing tolerance and thermonastic behaviour (temperature-induced leaf movement). R. catawbiense exhibits thermonasty while R. ponticum does not. Differences in leaf freezing tolerance (LT(50)), photosynthesis, photoinhibition, early light-induced proteins (ELIPs) gene expression, and accumulation of antioxidant metabolites and enzymes during seasonal CA were investigated. During seasonal CA, maximum photosynthetic rate (P(max)) and maximum quantum efficiency of PSII (F(v)/F(m)) were significantly down-regulated Compared with R catawbiense, R. ponticum showed less photoinhibition and higher overall accumulation (in magnitude) of antioxidant systems while R. catawbiense exhibited more efficient up-regulation of ELIP expression and antioxidant system (i.e, greater efficiency of increasing this pool in winter months relative to the summer levels). The two species respond differently to winter conditions and have evolved strategies to avoid, reduce and/or tolerate photooxidative stress in winter. These include down-regulation of photosynthesis and up-regulation of ELIPs and antioxidant systems, together with specialized leaf anatomy and thermonasty behaviour. Published by Elsevier Ireland Ltd

AB Vitamin C (ascorbic acid) is an essential component for collagen biosynthesis and also for the proper functioning of the cardiovascular system in humans. Unlike most of the animals, humans lack the ability to synthesize ascorbic acid on their own due to a mutation in the gene encoding the last enzyme of ascorbate biosynthesis. As a result, vitamin C must be obtained from dietary sources like plants. In this Study, we have developed transgenic potato plants (Solanum tuberosum L. cv. Taedong Valley) over-expressing strawberry GalUR gene under the control of CaMV 35S promoter with increased ascorbic acid levels. Integration of the GalUR gene in the plant genome was confirmed by PCR and Southern blotting. Ascorbic acid (AsA) levels in transgenic tubers were determined by high-performance liquid chromatography (HPLC). The over-expression of GalUR resulted in 1.6-2-fold increase ill AsA in transgenic potato and the levels of AsA were positively correlated with increased GalUR activity. The transgenic lines with enhanced vitamin C content showed enhanced tolerance to abiotic stresses induced by methyl viologen (MV), NaCl or mannitol as compared to untransformed control plants. The leaf disc senescence assay showed better tolerance in transgenic lines by retaining higher chlorophyll as compared to the untransformed control plants. Present study demonstrated that the over-expression of GalUR gene enhanced the level of AsA in potato tubers and these transgenics performed better under different abiotic stresses as compared to untransformed control.

AB Steps to facilitate inter-jurisdictional collaboration nationally and continentally have been critical for implementing and conducting coordinated wildlife rabies management programs that rely heavily on oral rabies vaccination (ORV). Formation of a national rabies management team has been pivotal for coordinated ORV programs in the United States of America. The signing of the North American Rabies Management Plan extended a collaborative framework for coordination of surveillance, control, and research in border areas among Canada, Mexico, and the US. Advances in enhanced surveillance have facilitated sampling of greater scope and intensity near ORV zones for improved rabies management decision-making in real time. The value of enhanced surveillance as a complement to public health surveillance was best illustrated in Ohio during 2007, where 19 rabies cases were detected that were critical for the formulation of focused contingency actions for controlling rabies in this strategically key area. Diverse complexities and challenges are commonplace when applying ORV to control rabies in wild meso-carnivores. Nevertheless, intervention has resulted in notable successes, including the elimination of an arctic fox (Vulpes lagopus) rabies virus variant in most of southern Ontario, Canada, with ancillary benefits of elimination extending into Quebec and the northeastern US. Progress continues with ORV toward preventing the spread and working toward elimination of a unique variant of gray fox (Urocyon cinereoargenteus) rabies in west central Texas. Elimination of rabies in coyotes (Canis latrans) through ORV contributed to the US being declared free of canine rabies in 2007. Raccoon (Procyon lotor) rabies control continues to present the greatest challenges among meso-carnivore rabies reservoirs, yet to date intervention has prevented this variant from gaining a broad geographic foothold beyond ORV zones designed to prevent its spread from the eastern US. Progress continues toward the development and testing of new bait-vaccine combinations that increase the chance for improved delivery and performance in the diverse meso-carnivore rabies reservoir complex in the US.

AB The grafting effect of maleic anhydride (MA) as an interfacial bonding agent and its influence on the tensile strength properties of thermomechanical pulp handsheet-isotactic polypropylene (iPP) film laminates was studied. For the MA treated with benzoyl peroxide (BPO) as an initiator, tensile strength properties increased 76% with PP film over untreated laminates. The optimal strength properties were obtained with a MA and BPO ratio of 2:1. A strong correlation was observed between the number of fibers in the web and tensile strength properties for both handsheet drying conditions. The R(2) values were 0.95 for air-dry conditions and 0.94 from oven-dry conditions. Scanning electron microscopy images also showed the effectiveness of MA loading on the surface of thermomechanical pulp fibers due to increased fiber failure, which occurred without fiber being pulled out from the PP matrixes. Crystallinity and heat flow were determined using differential scanning calorimetry (DSC) and increased as expected as the ratio of MA and BPO increased from 0:0 to 2:1. These results were also in accordance with the morphological observations at the fracture surface, Fourier transform infrared spectra, and thermal analysis. POLYM. COMPOS., 30:1864-1872, 2009.

AB This article describes the physicochemical (mechanical and swelling) and morphological characterization of poly(acrylamide) and methylcellulose (PAAm-MC) hydrogels synthesized with different formulations by the free radical polymerization method. The structure-property relationship of the PAAm-MC hydrogels is very important for application of these materials in different fields. Results showed that the properties of the PAAm-MC hydrogels can be controlled by varying the acrylamide (AAm) and N',N-methylene-bis-acrylamide (MBAAm) concentrations and methylcellulose (MC) content. Increase of AAm and MBAAm concentrations causes a pronounced decrease in swelling degree (SD) values and porosity, and an increase in mechanical properties. Increasing the MC concentration caused an increase in SD values and porosity, but decrease in maximum load and modulus of elasticity because of the increase in the hydrogel hydrophilicity due to incorporation of hydroxyl groups from MC chains. PAAm-MC hydrogels are excellent candidates for several applications, such as matrices for cell transplantation, controlled release (agrochemicals and drugs), tissue repair and regeneration. POLYM.

AB Objectives. The effects of a Boy Scout Five-A-Day Badge program on fruit juice (FJ) and low-fat vegetable (LV) consumption were evaluated using a two-condition (treatment, active-attention-placebo-control) group randomized trial, with three data collection periods (baseline, immediate post, 6-month post).
Methods. Forty-two Boy Scout troops (n=473, 10- to 14-year-old Scouts) in Houston, TX, were randomly assigned to condition. The 9-week program included approximately 30 min of weekly troop time, plus similar to 25 min of weekly Internet programming. The intervention was delivered in two waves (Spring and Fall). Data were collected in 2003-2004, and analyses were completed in 2008. Main outcomes were FJ and LV consumption (validated food frequency questionnaire). FV self-efficacy, preferences, and home availability were also measured.
Results. Significant increases in FJ consumption (p=.003), FJ home availability (p=.009), and LV self-efficacy (p=.004) were observed among the intervention group immediately following the intervention but were not maintained 6 months later.
Conclusion. A Boy Scout troop-plus-Internet intervention promoting FJ and LV consumption resulted in short-term changes in FJ consumption among U.S. Boy Scouts. Future research should investigate ways to extend these results to LV and maintain the increases over time. Published by Elsevier Inc.

Biodiesel has many important technical advantages compared to petrodiesel including superior inherent lubricity, low toxicity, high (non-flammable) flash point and biodegradability, very low or negligible sulfur content and lower exhaust emissions of most regulated species. Biodiesel is generally produced by transesterification of the lipid with a short-chain monohydric alcohol. This process may leave behind very small (trace) concentrations of minor constituents such as saturated monoacylglycerols (MAGs) or free steryl glucosides (FStGs). These materials have high melting points and very low solubilities allowing them to form solid residues when stored during cold weather. Blending with petrodiesel exacerbates the problem. Settling solid residues were found to clog fuel filters in fuel dispensers and vehicles. In response to documented problems the biodiesel industry in the United States collaborated with the American Society of Testing and Materials (ASTM) to develop a cold soak filter-ability performance test that will help identify fuels that may have a propensity to clog filters if exposed to long-term storage in cold weather.

AB Recent years have seen the progression of light detection and ranging (lidar) from the realm of research to operational use in natural resource management. Numerous government agencies, private industries, and public/private stakeholder consortiums are planning or have recently acquired large-scale acquisitions, and a national U.S. lidar acquisition is likely before 2020. Before it is feasible for land managers to integrate lidar into decision making, resource assessment, or monitoring across the gambit of natural resource applications, consistent standards in project planning, data processing, and user-driven products are required. This paper introduces principal lidar acquisition parameters, and makes recommendations for project planning, processing, and product standards to better serve natural resource managers across multiple disciplines.

DE spectral vegetation index; soil noise; soil line; vegetation isoline
AB This paper introduces derivations of soil line influences on two-band vegetation indices (VIs) and vegetation isolines in the red and near infra-red reflectance space. Soil line variations are described as changes in the soil line parameters (slope and offset) and the red reflectance of the soil surface. A general form of a VI model equation written as a ratio of two linear functions (e.g., NDVI and SAVI) was assumed. It was found that relative VI variations can be approximated by a linear combination of the three soil parameters. The derived expressions imply the possibility of estimating and correcting for soil-induced bias errors in VIs and their derived biophysical parameters, caused by the assumption of a general soil line, through the use of external data sources such as regional soil maps.

AB Applications of LiDAR remote sensing are exploding, while moving from the research to the operational realm. Increasingly, natural resource managers are recognizing the tremendous utility of LiDAR-derived information to make improved decisions. This review provides a cross-section of studies, many recent, that demonstrate the relevance of LiDAR across a suite of terrestrial natural resource disciplines including forestry, fire and fuels, ecology, wildlife, geology, geomorphology, and surface hydrology. We anticipate that interest in and reliance upon LiDAR for natural resource management, both alone and in concert with other remote sensing data, will continue to rapidly expand for the foreseeable future.

DE crop residue; non-photosynthetic vegetation; ASTER; agricultural remote
sensing
AB Unlike traditional ground-based methodology, remote sensing allows for the rapid estimation of crop residue cover (f(R)). While the Cellulose Absorption Index (CAI) is ideal for f(R) estimation, a new index, the Shortwave Infrared Normalized Difference Residue Index (SINDRI), utilizing ASTER bands 6 and 7, is proposed for future multispectral sensors and would be less costly to implement. SINDRI performed almost as well as CAI and better than other indices at five locations in the USA on multiple dates. A minimal upgrade from one broad band to two narrow bands would provide f(R) data for carbon cycle modeling and tillage verification.

AB The high-resolution Experimental Advanced Airborne Research LIDAR (EAARL) is a new technology for cross-environment surveys of channels and floodplains. EAARL measurements of basic channel geometry, such as wetted cross-sectional area, are within a few percent of those from control field surveys. The largest channel mapping errors are along stream banks. The LIDAR data adequately support 1D and 2D computational fluid dynamics models and frequency domain analyses by wavelet transforms. Further work is needed to establish the stream monitoring capability of the EAARL and the range of water quality conditions in which this sensor will accurately map river bathymetry.

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

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

AB Soil erosion due to annual cropping on highly erodible farmland is a major ecological concern in the wheat growing regions of Washington State. In response to requests from farmers, the winter wheat breeding program at Washington State University has been developing perennial wheat selected from crosses between wild wheatgrass species and commonly grown annual wheat cultivars. In 2005/06, we conducted field trials of the most promising perennial wheat breeding lines derived from interspecific crosses between tall wheatgrass (Thinopyrum elongatum) and bread wheat (Triticum aestivum). Thirty-one perennial breeding lines and two annual winter wheat cultivars; were evaluated for nutritional value in the form of grain mineral concentration, multiple baking and milling quality traits, and ease of grain threshability. The objective of this study was to identify the strengths and weaknesses of these post-harvest traits in the perennial wheat lines derived from these interspecific crosses. Mineral nutrient concentrations in the perennial lines were 44, 40, 24, 23, 32, 30 and 33% higher than the annual control cultivars for calcium, copper, iron, magnesium, manganese, phosphorus and zinc, respectively. The annual cultivars had a higher grain mineral content per unit area of land than the perennial lines, due primarily to the higher grain yields of the annual cultivars. Compared to the annual wheat cultivars, the perennial lines produced grain with smaller seed size, lower test weight and reduced flour yield, mix time and loaf volume. Protein content was 3.5-4.5% higher in the perennial lines than in the annual cultivars. The threshability index (TI) ranged from 0.63 to 0.89 in the perennials (mu = 0.75); significantly lower than the mean TI of the annual cultivars (mu = 0.97). The significant genotype x location interaction found for TI suggests that the variation in annual precipitation positively influenced some perennial lines to express greater threshability. In addition to transferring traits important to the perennial growth habit in wheat, the wild wheatgrass species also introduced beneficial characteristics (i.e. increased protein and mineral concentration) and deleterious traits (poor threshing grain and inferior baking qualities). This research gives researchers a platform from which to direct further research and selection in the development of perennial wheat.

Model results indicated that bulk lettuces were shock substitutes (in contrast to price substitutes) as consumers purchased fewer spinach products and more bulk lettuce of all types. Results also showed that consumers initially moved away from bagged salads without spinach; but consumer confidence rebounded quickly and expenditures rose. Over a period of sixty-eight weeks, retail expenditures decreased 20% for bagged spinach and 1% for bulk spinach. Retail expenditures for all leafy greens declined just 1%.

AB The impact of organic participation on milk production costs is evaluated using data from a nationwide survey of dairy operations. Organic dairies have estimated costs about $5 to $8 per cwt higher than conventional dairies. They also receive an average milk price premium of $6.69 per cwt in 2005. Production costs are estimated to be only $3 to $4 per cwt higher among pasture-based dairies. Results suggest that small conventional dairies may consider converting to the organic approach, but startup organic dairies are not likely unless they can enter at a much larger scale than the industry norm or can utilize pasture as a primary dairy feed source.

AB This article provides a unique perspective to why U.S. producers' hedging practices are not consistent with the price-risk management literature. We conduct a formal test of income support program impacts with survey data from South Africa and the United States, which have different producer income support policies. We find that producing in a supported environment (U.S.) decreases hedging for preplanting and preharvest expected yields by 30.39% and 20.03%, respectively. This study raises issues for further inquiry regarding both comparative agricultural lending practices and the relative costs of price-risk management tools.

AB This article examines the importance and value of attending the annual summer conference of the Agricultural and Applied Economics Association (AAEA) by U.S. Federal government economists. A choice-based conjoint analysis of government funding of five research-facilitating resources, including travel and nontravel resources, shows that respondents have a clear preference for their government agency funding the travel-related resources over the other resources. Furthermore, using the contingent valuation method, we find that these economists would have been willing to pay $195 to $620 to have attended their last AAEA conference, with the bounds on this range depending on modeling assumptions.

ID IMPACT
AB Livestock contributes significantly to the world economy. However, animal diseases are still a major constraint on economic growth, the reduction of poverty and food security. Among the most significant diseases is foot and mouth disease (FMD), a highly contagious, multi-species animal disease with a devastating impact on national economies and trade. Less obvious is the severe constraint that FMD places on both development and the reduction of poverty in developing countries where this disease is endemic. As a result of its global implications and the high costs that it imposes on society, FMD is an infectious disease whose control and prevention are recognised as being a global public good.
Moving towards the global control of FMD should be considered a priority for donors, but will require long-term commitment from all parties, strong political will from governments and concerted financial support from donors. Areas of intervention must fall within the framework of programmes developed by international organisations, such as the Food and Agriculture Organization of the United Nations (FAO) and the World Organisation for Animal Health (OIE), through the FAO/OIE Global Framework for the Progressive Control of FMD and Other Transboundary Animal Diseases, as well as the disease control programmes of the regions concerned. Such a goal should specifically focus on analytical work (micro-economic impact and cost-benefit analyses of FMD at the household level and on the poor), research, surveillance networks, communication, monitoring and evaluation, and continuous strengthening of Veterinary Services.

AB The conversion of biomass, specifically lignocellulosic biomass, into fuels and chemicals has recently gained national attention as an alternative to the use of fossil fuels. Increasing the concentration of the biomass solids during biochemical conversion has a large potential to reduce production costs. These concentrated biomass slurries have highly viscous, non-Newtonian behavior that poses several technical challenges to the conversion process. A collaborative effort to measure the rheology of a biomass slurry at four separate laboratories has been undertaken. A comprehensive set of rheological properties were measured using several different rheometers, flow geometries, and experimental methods. The tendency for settling, water evaporation, and wall slip required special care when performing the experiments. The rheological properties were measured at different concentrations up to 30% insoluble solids by mass. The slurry was found to be strongly shear-thinning, to be viscoelastic, and to have a significant concentration-dependent yield stress. The elastic modulus was found to be almost an order of magnitude larger than the loss modulus and weakly dependent on frequency. The techniques and results of this work will be useful to characterize other biomass slurries and in the design of biochemical conversion processing steps that operate at high solids concentrations.

AB Seed shelf-life or longevity is difficult to predict or to measure on a practical time scale. Predictive models suggest that water has the same effect on ageing rate for all seed lots within a species and that initial seed quality is the dominating factor explaining within-species variation. These assumptions are used in,accelerated ageing' or 'controlled deterioration' (AA/CD) tests, which are commonly used to predict seed longevity in commercial and research applications. In this study, we describe within-species variation of longevity for seeds of Secale cereale and S. strictum (cultivated rye and its wild progenitor) under typical dry storage conditions of a genebank, and show that initial seed quality is an important, but not sole, factor explaining measured longevity. We also test the correlation of seed longevity, measured under humid and dry conditions, using 50 cultivars of rye, wheat (Triticum aestivum) and the intergeneric cross triticale, to assess how well AA/CD tests predict seed shelf-life during dry storage. Known differences in longevity between wheat and rye were confirmed at all water contents, and triticale seeds demonstrated intermediate behaviour. Longevity measured for humid and dry conditions were weakly correlated when comparisons included all grain types and were not correlated in with in-g rain-type comparisons. Response to moisture varied among cultivars. These findings do not support assumptions made in seed ageing models that use AA/CD tests. Our results suggest that more traits are involved in the expression of seed longevity than those typically measured in studies of initial seed vigour.

AB A principal goal of seed germination modelling for wild species is to predict germination timing under fluctuating field conditions. We coupled our previously developed hydrothermal time, thermal and hydrothermal afterripening time, and hydration-dehydration models for dormancy loss and germination with field seed zone temperature and water potential measurements from early summer through autumn to develop predictions of germination timing for Bromus tectorum at a semi-arid site in north-central Utah, USA. Model predictions were tested with a validation dataset based on concomitant seed retrieval experiments in 2 years. Predictions were generally in agreement with observed field germination time courses, even though integration across multiple precipitation events was necessary. Success of the modelling effort hinged on two factors. First, we used a soil capacitance sensor that measured seed zone (5 mm soil depth) water content accurately over a wide range. Second, simulations were built using physiologically based threshold models that can incorporate differences in germination timing for multiple germination fractions and for multiple stages of dormancy loss. Our results suggest that simulation models using hydrothermal time concepts can predict field germination phenology accurately. Seeds in this study integrated their experiences in a widely fluctuating environment in a manner consistent with the assumptions of hydrothermal time. Such threshold-based models also have the advantage of generality, as these concepts can be applied to many different species, environments and weather scenarios.

AB Methods to predict soil hydraulic properties frequently requite information on the particle size distribution (PSD). The objectives of this study were to investigate various protocols for rapidly measuring PSD using the laser diffraction technique, compare the obtained PSD with those determined using the traditional hydrometer-and-sieves method (HSM), and assess the accuracy of soil hydraulic properties predicted from the measured PSD. Ten soil samples encompassing a wide textural range were analyzed using the HSM and 3 different laser diffraction methods (LDM1, LDM2, and LDM3). In LDM1, the soil sample was thoroughly mixed before analysis. In LDM2, the sand fraction was sieved out and analyzed separately from the silt-clay fraction. LDM3 was similar to LDM2 except that the silt-clay fraction was diluted so that a large sample volume could be used while maintaining an acceptable level of obscuration. LDM2 and LDM3 improved the agreement between the PSD with the HSM in comparison to LDM1, without the need of altering the Mie theory parameters or the use of scaling factors. Moreover, a reasonable prediction of measured saturated hydraulic conductivity and water retention curve was achieved when using the PSD from LDM2 and LDM3, in conjunction with bulk density information.

AB The characterization of organic matter in agroecosystems is important because of its involvement in many important soil ecosystem processes. Humic acid, fulvic acid, and water-extractable organic matter from a 9-year agroecosystem study investigating the effects of tillage, cropping system, and N source was characterized using multidimensional fluorescence spectroscopy with parallel factor analysis (PARAFAC). The fluorescence spectra suite containing all three types of organic matter fractions was modeled by five PARAFAC components. The distribution of component concentrations was unique to each type of organic matter fraction, indicating that these operational extracted fractions reflect differing chemical pools of soil organic matter. The three treatment factors (tillage, cropping, and N source) investigated in this study did not affect the component distribution of the humic and fulvic acid fractions that are regarded as the refractory pools of soil organic matter. In contrast, the component distribution of the more labile water-extractable organic matter fraction was significantly affected by the N source treatment. The results of this study support the use of multidimensional fluorescence spectroscopy with PARAFAC as a method to investigate how management practices of agroecosystems affect the dynamics and chemical nature of soil organic matter pools.

AB Poultry litter (PL) is an inexpensive and effective source of plant nutrients. However, overapplication could result in phosphorus (P) and heavy metal accumulation in soils. A field experiment evaluating PL application to a Cecil soil used for cotton and corn production has been maintained for 10 years. At the end of the cotton phase (i.e., the first 5 years), PL annually applied at 4.5 Mg ha(-1) did not increase concentrations of total soil P, zinc (Zn), Cu, or manganese. During the corn phase (i.e. the second 5 years), PL application rates were increased from two to four times that used for cotton partly because of corn's greater N demand. With this change, the average total P in the surface 15-cm soil nearly doubled to about 560 mg kg(-1) of dry soil in both conventional till and no-till fields at the end of the corn phase. During the same time, Cu increased from 7 to 22 mg kg(-1) and Zn increased from 17 to 32 mg kg(-1) of dry soil. Levels of manganese were basically unchanged. Total P and Cu also increased in the 15- to 30-cm depth, with concentrations in the 0 to 15 cm being 1.8 to two times that in the 15 to 30 cm for P and approximately two times for Cu. Relationships between extractable versus total P and Zn changed at a threshold point beyond which extractable P and Zn increased at more than double the initial rate. It seems that once accumulation of P and Zn exceeded the soil buffer capacity nutrient availability was significantly altered. Therefore, close monitoring of soil nutrients especially P is essential to avoid over application of PL that may potentially pose environmental risks for water Pollution.

AB Many soils in the semiarid Mediterranean Ebro Valley of Spain are prone to physical and chemical degradation due to their silty texture, low organic matter content, and presence of carbonates, gypsum or other soluble salts. Rainfed agriculture on these soils is also hindered by the scarcity of water. No-tillage can increase plant-available water and soil organic matter, thus helping overcome most factors limiting crop production in this area. Our objective was to determine how conventional- and no-tillage practices affected soil physical quality indicators and water availability in an on-farm study in the Ebro Valley. Soil samples were collected from 0 to 5-, 5 to 15-, and 15 to 30-cm depth increments within adjacent farmer-managed conventional- and no-tillage fields in 2007 and 2008. Both fields were managed for continuous barley (Hordeum vulgare L.) production. The soil at both sites is a silt loam (Haplic Calcisol). Aggregate-size distribution and stability, soil water retention characteristics, organic carbon, and total carbonates were determined in 2007. Pore-size distribution was estimated from the water retention curve. Penetration resistance, soil bulk density and field water content during the entire crop growing season were measured for both fields in 2008. Aggregate dry mean weight diameter and stability in water were 1.2 and 2.2 times greater, respectively, under no-tillage than conventional tillage due to reduced mechanical disturbance and increased soil organic carbon content. Bulk density was 1.12 times greater (P < 0.1) under no-tillage only in the 0-5-cm depth. Two times greater penetration resistance to a depth of 15 cm in this treatment was related to bulk density and aggregates stability. Field water content was greater with no-tillage than conventional tillage during the driest months in 2008. The volume of equivalent diameter pores (0.2-9 mu m) was 1.5 times higher under no-tillage. This increased plant-available water content and doubled barley production under no-tillage in 2008, which was a very dry year. We conclude that despite the greater penetration resistance under no-tillage, increased water availability as a result of improved structure characteristics was more important for crop yield. This suggests that producers should seriously consider adopting no-tillage practices for soil conservation in semiarid degraded areas like the one studied. (C) 2009 Elsevier B.V. All rights reserved.

AB The arundo wasp, Tetramesa romana Walker, has been permitted as a biological control agent for the invasive perennial grass, the giant reed, Arundo donax L. Evidence of adventive populations of the arundo wasp in the Lower Rio Grande Basin was confirmed with a spatio-temporal survey spanning more than 350 river miles. A total of 2,414 adult females of T. romana was collected during a 14-month period of study in 2008-2009. This study documents the initial locations and regional expansion of two adventive populations of T romana, centered around the cities of Eagle Pass and Laredo, TX. Peaks in T romana abundance in August 2008 and June 2009 indicate a region-wide positive association between abundance of T romana and warm summer temperatures. Correlations between site-specific abundance data and weather suggest the presence of population-specific associations with both temperature and rainfall.

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

TI Economic Implications for the Biological Control of Arundo donax: Rio

SO SOUTHWESTERN ENTOMOLOGIST

ID GIANT REED
AB Giant reed, Arundo donax L., is a large, bamboo-like plant native to the Mediterranean region. It has invaded several thousand hectares of the Rio Grande riparian habitat in Texas and Mexico. The United States Department of Agriculture-Agricultural Research Service (USDA-ARS) is investigating four herbivore insects as potential biological control agents for giant reed. One of the most important reasons for targeting this invasive weed is to reduce its impact on available water supplies, especially in the Rio Grande Basin. This study examined selected economic implications of this program for agricultural water users in the U.S. The research included (a) estimating the value of the water saved (to agricultural purposes) by reduction of giant reed, (b) benefit-cost analyses, (c) regional economic impact analyses, and (d) an estimate of the per-unit life-cycle cost of water saved during a 50-year planning horizon (2009 through 2058).
Positive results related to the benefit-cost ratio, economic impact analyses, and competitive results for the per-unit life-cycle cost of saving water are associated with the biological control project for giant reed. The benefit-cost ratio, calculated with normalized prices, indicates $4.38 of benefits for every dollar of public investment. According to 2009 results for the economic impact analyses, economic output is $22,000, value-added is $11,000, and no employment is supported by the water savings from giant reed. Additionally, the per-unit cost of water saved is $44.08, a value comparable to other projects designed to increase water supply for the region. These results indicate this program will have positive net economic implications for the U.S. and the Lower Rio Grande Valley of Texas.

ID TABACI THYSANOPTERA; SOUTH TEXAS
AB Species, seasonal abundance, damage, control, and predaceous natural enemies of thrips (Thysanoptera: Thripidae) on cotton, Gossypium hirsutum L., were determined at two sites from 2005 to 2007 in the Lower Rio Grande Valley of Texas. Thrips can stunt growth and reduce yield potential. Seven species of thrips were found. When the cotton field was 0.5 km from commercial onion, Allium cepa L., the predominant species were western flower thrips, Frankliniella occidentalis (Pergande) (61.7%) and onion thrips, Thrips tabaci Lindeman (27.2%). A cotton field 50 km from a commercial onion-growing area was infested with western flower thrips (68.5%) and bean thrips, Caliothrips fasciatus (Pergande) (29.2%). At both fields, cotton seedlings from the cotyledon to 3-4-true leaf stages were most susceptible to onion thrips. Western flower thrips and bean thrips were found predominantly on 5- to 6-true-leaf stage and older cotton. Thrips were found in cotton at the beginning of the growing season and increased gradually in abundance, peaking in mid-May to late June. Predators on cotton were: minute pirate bugs, Orius spp.; lady beetles, Hippodamia spp.; green lacewing, Chrysopa rufilabris (Burmeister); bigeyed bugs, Geocoris spp.; spiders, Argiope spp., and syrphid flies, Syrphus spp. Orius spp. were the most abundant predators (69.5% on nontreated cotton). Heavy rainfall temporarily reduced abundance of thrips on cotton. The systemic insecticides thiamethoxam (Cruiser (TM)) and imidacloprid (Gaucho Grande (TM)) applied to seeds protected cotton from thrips for as long as 30 days after planting.

Cotton was most suitable for sweetpotato whitefly, and bean was most suitable for greenhouse whitefly. No significant differences were found between these two whitefly species on sweet potato. Preimaginal mortality of sweetpotato whitefly on cotton was 35.2% versus 77.3% of greenhouse whitefly. Developmental time of sweetpotato whitefly was significantly shorter (17.5 days) than that of greenhouse whitefly (23.2 days). The mortality and developmental time of bandedwinged whitefly did not differ on the different host plants. Parasitism by Er. mundus was greatest in sweetpotato whitefly and least in greenhouse whitefly when both whiteflies were reared on cotton. Parasitism of bandedwinged whitefly was intermediate. Parasitism by En. pergandiella was significantly greater than that by Er. mundus attacking the same whitefly species reared on bean or cotton, except parasitism of sweetpotato whitefly. Emergence of Er. mundus was greatest from sweetpotato whitefly on cotton, and least for bandedwinged whitefly on bean. Emergence of En. pergandiella was significantly greater than that of Er. mundus among host plants and whitefly species except sweetpotato whitefly.

AB Stable flies, Stomoxys calcitrans L., are important pests of confined and pasture cattle. They have been reared in the laboratory to study their biology and to test new methods of control. Research on rearing modifications has concentrated on developing larval diets from materials locally abundant. Under current protocols, pupae form in the medium. Aggregations of pupae were located and removed, often with a considerable amount of extraneous material. Various methods have been developed to separate the pupae from waste material. We describe a method by which wandering larvae are enticed to leave the medium prior to pupariation. The larvae were attracted to a moist cloth on a shelf positioned at the end of the rearing pan. Almost 85% of the wandering larvae were collected on the shelf. This simplifies obtaining clean pupae and allows for collecting pupae of known age for experimental work. We also include data on the rate at which the larvae wandered onto the shelf under conditions we used in the laboratory.

AB Sweet sorghum has the potential to become a versatile feedstock for large-scale bioenergy production given its sugar from stem juice, cellulose/hemicellulose from stalks, and starch from grain. However, for researchers to maximize its feedstock potential a first step includes additional evaluations of the 2,180 accessions with varied origins in the US historic sweet sorghum collection. To assess genetic diversity of this collection for bioenergy breeding and population structure for association mapping, we selected 96 accessions and genotyped them with 95 simple sequence repeat markers. Subsequent genetic diversity and population structure analysis methods identified four subpopulations in this panel, which correlated well with the geographic locations where these accessions originated or were collected. Model comparisons for three quantitative traits revealed different levels of population structure effects on flowering time, plant height, and brix. Our results suggest that diverse germplasm accessions curated from different geographical regions should be considered for plant breeding programs to develop sweet sorghum cultivars or hybrids, and that this sweet sorghum panel can be further explored for association mapping.

AB Publicly available genomic tools help researchers integrate information and make new discoveries. In this paper, we describe the development of immortal mapping populations of rapid cycling, self-compatible lines, molecular markers, and linkage maps for Brassica rapa and B. oleracea and make the data and germplasm available to the Brassica research community. The B. rapa population consists of 160 recombinant inbred (RI) lines derived from the cross of highly inbred lines of rapid cycling and yellow sarson B. rapa. The B. oleracea population consists of 155 double haploid (DH) lines derived from an F1 cross between two DH lines, rapid cycling and broccoli. A total of 120 RFLP probes, 146 SSR markers, and one phenotypic trait (flower color) were used to construct genetic linkage maps for both species. The B. rapa map consists of 224 molecular markers distributed along 10 linkage groups (A1-A10) with a total distance of 1125.3 cM and a marker density of 5.7 cM/marker. The B. oleracea genetic map consists of 279 molecular markers and one phenotypic marker distributed along nine linkage groups (C1-C9) with a total distance of 891.4 cM and a marker density of 3.2 cM/marker. A syntenic analysis with Arabidopsis thaliana identified collinear genomic blocks that are in agreement with previous studies, reinforcing the idea of conserved chromosomal regions across the Brassicaceae.

AB Stagonospora nodorum, casual agent of Stagonospora nodorum blotch (SNB) of wheat, produces a number of host-selective toxins (HSTs) known to be important in disease. To date, four HSTs and corresponding host sensitivity genes have been reported, and all four host-toxin interactions are significant factors in the development of disease. Here, we describe the identification and partial characterization of a fifth S. nodorum produced HST designated SnTox4. The toxin, estimated to be 10-30 kDa in size, was found to be proteinaceous in nature. Sensitivity to SnTox4 is governed by a single dominant gene, designated Snn4, which mapped to the short arm of wheat chromosome 1A in a recombinant inbred (RI) population. The compatible Snn4-SnTox4 interaction is light dependent and results in a mottled necrotic reaction, which is different from the severe necrosis that results from other host-toxin interactions in the wheat-S. nodorum pathosystem. QTL analysis in a population of 200 RI lines derived from the Swiss winter wheat varieties Arina and Forno revealed a major QTL for SNB susceptibility that coincided with the Snn4 locus. This QTL, designated QSnb.fcu-1A, explained 41.0% of the variation in disease on leaves of seedlings indicating that a compatible Snn4-SnTox4 interaction plays a major role in the development of SNB in this population. Additional minor QTL detected on the short arms of chromosomes 2A and 3A accounted for 5.4 and 6.0% of the variation, respectively. The effects of the three QTL were largely additive, and together they explained 50% of the total phenotypic variation. These results provide further evidence that host-toxin interactions in the wheat-S. nodorum pathosystem follow an inverse gene-for-gene model.

AB In this association mapping study, a tri-species hybrid, [Gossypium arboreum x (G. hirsutum x G. aridum)(2)], was crossed with MD51ne (G. hirsutum) and progeny from the cross were used to identify and map SSR markers associated with reniform nematode (Rotylenchulus reniformis) resistance. Seventy-six progeny (the 50 most resistant and 26 most susceptible) plants were genotyped with 104 markers. Twenty-five markers were associated with a resistance locus that we designated Ren (ari) and two markers, BNL3279_132 and BNL2662_090, mapped within 1 cM of Ren (ari) . Because the SSR fragments associated with resistance were found in G. aridum and the bridging line G 371, G. aridum is the likely source of this resistance. The resistance is simply inherited, possibly controlled by a single dominant gene. The markers identified in this project are a valuable resource to breeders and geneticists in the quest to produce cotton cultivars with a high level of resistance to reniform nematode.

AB Zucchini yellow mosaic virus (ZYMV) is one of the most economically important potyviruses infecting cucurbit crops worldwide. Using a candidate gene approach, we cloned and sequenced eIF4E and eIF(iso)4E gene segments in watermelon. Analysis of the nucleotide sequences between the ZYMV-resistant watermelon plant introduction PI 595203 (Citrullus lanatus var. lanatus) and the ZYMV-susceptible watermelon cultivar 'New Hampshire Midget' ('NHM') showed the presence of single nucleotide polymorphisms (SNPs). Initial analysis of the identified SNPs in association studies indicated that SNPs in the eIF4E, but not eIF(iso)4E, were closely associated to the phenotype of ZYMV-resistance in 70 F(2) and 114 BC(1R) progenies. Subsequently, we focused our efforts in obtaining the entire genomic sequence of watermelon eIF4E. Three SNPs were identified between PI 595203 and NHM. One of the SNPs (A241C) was in exon 1 and the other two SNPs (C309A and T554G) were in the first intron of the gene. SNP241 which resulted in an amino acid substitution (proline to threonine) was shown to be located in the critical cap recognition and binding area, similar to that of several plant species resistance to potyviruses. Analysis of a cleaved amplified polymorphism sequence (CAPS) marker derived from this SNP in F(2) and BC(1R) populations demonstrated a cosegregation between the CAPS-2 marker and their ZYMV resistance or susceptibility phenotype. When we investigated whether such SNP mutation in the eIF4E was also conserved in several other PIs of C. lanatus var. citroides, we identified a different SNP (A171G) resulting in another amino acid substitution (D71G) from four ZYMV-resistant C. lanatus var. citroides (PI 244018, PI 482261, PI 482299, and PI 482322). Additional CAPS markers were also identified. Availability of all these CAPS markers will enable marker-aided breeding of watermelon for ZYMV resistance.

AB Fumonisins are mycotoxins produced by Fusarium verticillioides. They are toxic to animals and exert their effects through mechanisms involving disruption of sphingolipid metabolism. Fumonisins are converted to their hydrolyzed analogs by alkaline cooking (nixtamalization). Both fumonisins and hydrolyzed fumonisins are found in nixtamalized foods such as tortillas, and consumption of tortillas has been implicated as a risk factor for neural tube defects (NTD). Fumonisin B-1 (FB1) induced NTD when given (ip) to pregnant LM/Bc mice; however, neither the NTD induction potential of hydrolyzed fumonisin B-1 (HFB1) nor its affect on sphingolipid metabolism in pregnant mice have been reported. The teratogenic potential of FB1 and HFB1 was therefore compared using the LM/Bc mouse model. Dams were dosed (ip) with 2.5, 5.0, 10, or 20 mg/kg (< 49 mu mol/kg) body weight (bw) HFB1 on embryonic day (E)7-E8. Negative and positive control groups were given vehicle or 10 mg/kg (14 mu mol/kg) bw FB1, respectively. The high dose of HFB1 disrupted sphingolipid metabolism, albeit slightly, but did not cause maternal liver lesions or NTD (n = 8-10 litters per group). In contrast, 10 mg/kg bw FB1 markedly disrupted maternal sphingolipid metabolism, caused hepatic apoptosis in the dams, increased fetal death rates, and decreased fetal weights. Furthermore, NTD were found in all FB1-exposed litters (n = 10), and 66 +/- 24% of the fetuses were affected. The findings indicate that HFB1 does not cause NTD in the sensitive LM/Bc mouse model and only weakly disrupts sphingolipid metabolism at doses up to sevenfold higher (micromole per kilogram body weight basis) than the previously reported lowest observed adverse effect level for FB1.

AB Cyclopiazonic acid (CPA) is an indole-tetramic acid neurotoxin produced by some of the same strains of A. flavus that produce aflatoxins and by some Aspergillus oryzae strains. Despite its discovery 40 years ago, few reviews of its toxicity and biosynthesis have been reported. This review examines what is currently known about the toxicity of CPA to animals and humans, both by itself or in combination with other mycotoxins. The review also discusses CPA biosynthesis and the genetic diversity of CPA production in A. flavus/oryzae populations.

TI Fluorescence Polarization Immunoassay of Mycotoxins: A Review
SO TOXINS
LA English
DT Review
DE fluorescence polarization immunoassay; mycotoxins; review
AB Immunoassays are routinely used in the screening of commodities and foods for fungal toxins (mycotoxins). Demands to increase speed and lower costs have lead to continued improvements in such assays. Because many reported mycotoxins are low molecular weight (below 1 kDa), immunoassays for their detection have generally been constructed in competitive heterogeneous formats. An exception is fluorescence polarization immunoassay (FPIA), a homogeneous format that does not require the separation of bound and free labels (tracer). The potential for rapid, solution phase, immunoassays has been realized in the development of FPIA for many of the major groups of mycotoxins, including aflatoxins, fumonisins, group B trichothecenes (primarily deoxynivalenol), ochratoxin A, and zearalenone. This review describes the basic principles of FPIA and summarizes recent research in this area with regard to mycotoxins.

AB AGCVIII kinases regulate diverse developmental and cellular processes in plants. As putative mediators of secondary messengers, AGCVIII kinases potentially integrate developmental and environmental cues into specific cellular responses through substrate phosphorylation. Here we discuss the functionality and regulation of AGCVIII kinases. Specifically, we question the view that activities of AGCVIII kinases, like their animal counterparts, are regulated by a common regulator, 3-phosphoinositide-dependent protein kinase-1 (PDK1). Instead, increasing evidence suggests that Ca(2+) and phospholipids regulate AGCVIII kinases, by altering their activities or by affecting their subcellular localization. As AGCVIII kinases are at the crossroads of plant cellular signaling, they and the signaling networks in which they participate are keys to a better understanding of plant development and of interactions with their environment.

AB Raccoons are the reservoir for the raccoon rabies virus variant in the United States. To combat this threat, oral rabies vaccination (ORV) programs are conducted in many eastern states. To aid in these efforts, the genetic structure of raccoons (Procyon lotor) was assessed in southwestern Pennsylvania to determine if select geographic features (i.e., ridges and valleys) serve as corridors or hindrances to raccoon gene flow (e.g., movement) and, therefore, rabies virus trafficking in this physiographic region. Raccoon DNA samples (n = 185) were collected from one ridge site and two adjacent valleys in southwestern Pennsylvania (Westmoreland, Cambria, Fayette, and Somerset counties). Raccoon genetic structure within and among these study sites was characterized at nine microsatellite loci. Results indicated that there was little population subdivision among any sites sampled. Furthermore, analyses using a model-based clustering approach indicated one essentially panmictic population was present among all the raccoons sampled over a reasonably broad geographic area (e.g., sites up to 36 km apart). However, a signature of isolation by distance was detected, suggesting that widths of ORV zones are critical for success. Combined, these data indicate that geographic features within this landscape influence raccoon gene flow only to a limited extent, suggesting that ridges of this physiographic system will not provide substantial long-term natural barriers to rabies virus trafficking. These results may be of value for future ORV efforts in Pennsylvania and other eastern states with similar landscapes.

AB Southern tick-associated rash illness is a Lyme-like syndrome that occurs in the southern states. Borrelia lonestari, which has been suggested as a possible causative agent of southern tick-associated rash illness, naturally infects white-tailed deer (WTD; Odocoileus virginianus) and is transmitted by the lone star tick (Amblyomma americanum). To better understand the prevalence and distribution of Borrelia exposure among WTD, we tested WTD from 21 eastern states for antibodies reactive to B. lonestari using an indirect immunofluorescent antibody assay and Borrelia burgdorferi using the IDEXX SNAP (R) 4Dx (R) test. A total of 107/714 (15%) had antibodies reactive to B. lonestari, and prevalence of antibodies was higher in deer from southern states (17.5%) than in deer from northern states (9.2%). Using the SNAP 4DX test, we found that 73/723 (10%) were positive for B. burgdorferi, and significantly more northern deer (23.9%) were positive compared with southern deer (3.8%). Our data demonstrate that WTD are exposed to both Borrelia species, but antibody prevalence for exposure to the two species differs regionally and distributions correlate with the presence of Ixodes scapularis and A. americanum ticks.

AB P>Experiments comparing conventional and organic systems often report similar yields despite substantially higher weed abundance in the organic systems. A potential explanation for this observation is that weed-crop competition relationships differ between the two types of systems. We analysed weed and crop yield data from the Rodale Institute Farming Systems Trial (FST), which provides a unique 27-year dataset of a conventional (CNV) and two organic [manure (MNR) and legume (LEG)] soyabean (Glycine max (L.) Merr.) and maize (Zea mays L.) cropping systems. Average soyabean yields were similar between the MNR and CNV systems and only slightly reduced in the LEG system, whereas average maize yields did not differ among systems despite the two organic systems having more than four and six times greater weed biomass in soyabean and maize respectively. Plot-level weed biomass-crop yield relationships indicated that weed-crop competition differed between the two organic and CNV systems in maize, and was strongest in the CNV system, intermediate in the LEG system and weakest in the MNR system. These results suggest that organic cropping systems may be able to tolerate a greater abundance of weeds compared to conventional systems and that fertility management within organic systems may influence weed-crop competition.

ID PRESCRIBED FIRE; SOIL; SAGEBRUSH; STEPPE
AB Quantifying root biomass is critical to in estimation and understanding of ecosystem net primary, production, biomass partitioning, and belowground competition. We compared 2 methods for determining root biomass: a new soil-coring technique and traditional excavation of quantitative pits. We conducted the study in an existing joint Fire Sciences demonstration area in the central Great Basin. This area is representative of a shrub (sagebrush) ecosystem exhibiting tree (pinyon and juniper) encroachment. The demonstration area had a prescribed burn implemented 4 years prior to our study, and we sampled both Control and burned plots. The samples were stratified across 3 microsites (interspace, tinder shrub, and under tree) and 4 soil depths (0-8, 8-23, 23-38, and 38-52 cm) to determine the effects of plant life form and burning on root biomass. We found that estimates of total root biomass were similar between quantitative pits and our soil cores. However, cores tended to show a more even distribution of root biomass across all microsites and depths than did pits. Overall, results indicated that root biomass differs significantly among microsites and soil depths and that the amount of root biomass at a given depth differs among microsites. Burning reduced root biomass in our study by 23% and altered the spatial distribution of root mass.

AB Wind-pollinated dioecious plants often exhibit Spatial segregation I of I the sexes. This partial niche separation has most often been explored using abiotic niche axes. However, if the sexes are truly separated in space, then they e apt to encounter different plant species that may heavily affect growth and reproduction. Also, to the extent that their niches differ, the sexes may respond differently to the same co-occurring species. Here we examine interspecific interactions that influence male and female reproductive potential in Atriplex bonnevillensis. Using Emlen's interaction assessment, it technique which assesses species interactions based oil cover classes, we show that Salsola species compete significantly with females but not males, while Halog toll glomeratus competes with males but not females. The effect of competition only became apparent when we corrected for site-specific fertility. These results imply that differential competition must be considered when Studying dioecious plants that display spatial segregation of the sexes.

AB Broad-spectrum herbicide applications and improved harvesting efficiency of crops have reduced the availability of weed seeds and waste grains for game and nongame wildlife. Over the last decade, corn and soybean plantings have steadily increased ill the Prairie Pothole Region (PPR) of North Dakota, while sunflower plantings have declined. The PPR is an important corridor for migratory birds,;aid changes in food availabilities at stopover habitats may affect how food resources are used. In early spring 2003 and 2004, we compared bird use of harvested fields of sunflower, soybeans, small grains, and corn if the PPR of North Dakota. Across both years and all crop types, we observed 20,400 birds comprising 29 species. Flocks of Lapland Longspurs (Calcarius lapponicus) and Horned Larks (Eremophila alpestris) and flocks of Red-winged Blackbirds (Agelaius phoeniceus) made up 60% and 15%, respectively, of the bird counts. WC found that species richness and bird densities were higher in harvested sunflower fields and cornfields than in harvested small-grain and soybean fields, with soybean fields harboring the fewest species and lowest bird density Blackbird densities tended to he lower in fields tilled after fall harvest than in fields not tilled. These results suggest that some granivorous bird populations in the Northern Great Plains could he positively affected by planting of row crops with postharvest vertical structure (e.g., Sunflower, corn) and use of no-till land management practices.

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

AB Greater sage-grouse Centrocercus urophasianus Populations in North Dakota declined approximately 67% between 1965 and 2003, and the species is listed as a Priority Level 1 Species of Special Concern by the North Dakota Game and Fish Department. The habitat and ecology of the species at the eastern edge of its historical range is largely unknown. We investigated nest site selection by greater sage-grouse and nest survival in North Dakota during 2005 - 2006. Sage-grouse selected nest sites in sagebrush Artemisia spp. with more total vegetative cover, greater sagebrush density, and greater 1-m visual obstruction from the nest than at random sites. Height of grass and shrub (sagebrush) at nest sites were shorter than at random sites, because areas where sagebrush vas common were sites in low seral condition or dense clay or clay-pan soils with low productivity. Constant survival estimates of incubated nests were 33% in 2005 and 30% in 2006. Variables that described the resource selection function for nests were not those that modeled nest survival. Nest survival was positively influenced by percentage of shrub (sagebrush) cover and grass height. Daily nest survival decreased substantially when percentage of shrub cover declined below about 9% and when grass heights were less than about 16 cm. Daily nest survival rates decreased with increased daily precipitation.

AB The phylogeny and classification of tribe Aedini are delineated based on a cladistic analysis of 336 characters from eggs, fourth-instar larvae, pupae, adult females and males, and immature stage habitat coded for 270 exemplar species, including an outgroup of four species from different non-aedine genera. Analyses of the data set with all multistate characters treated as unordered under implied weights, implemented by TNT version 1.1, with values of the concavity constant K ranging from 7 to 12 each produced a single most parsimonious cladogram (MPC). The MPCs obtained with K values of 7-9 were identical, and that for K = 10 differed only in small changes in the relationships within one subclade. Because values of K < 7 and > 10 produced large changes in the relationships among the taxa, the stability of relationships exemplified by the MPC obtained from the K = 9 analysis is used to interpret the phylogeny and classification of Aedini. Clade support was assessed using parsimony jackknife and symmetric resampling. Overall, the results reinforce the patterns of relationships obtained previously despite differences in the taxa and characters included in the analyses. With two exceptions, all of the groups represented by two or more species were once again recovered as monophyletic taxa. Thus, the monophyly of the following genera and subgenera is corroborated: Aedes, Albuginosus, Armigeres (and its two subgenera), Ayurakitia, Bothaella, Bruceharrisonius, Christophersiomyia, Collessius (and its two subgenera), Dahliana, Danielsia, Dobrotworskyius, Downsiomyia, Edwardsaedes, Finlaya, Georgecraigius (and its two subgenera), Eretmapodites, Geoskusea, Gilesius, Haemagogus (and its two subgenera), Heizmannia (and subgenus Heizmannia), Hopkinsius (and its two subgenera), Howardina, Hulecoeteomyia, Jarnellius, Kenknightia, Lorrainea, Macleaya, Mucidus (and its two subgenera), Neomelaniconion, Ochlerotatus (subgenera Chrysoconops, Culicelsa, Gilesia, Pholeomyia, Protoculex, Rusticoidus and Pseudoskusea), Opifex, Paraedes, Patmarksia, Phagomyia, Pseudarmigeres, Rhinoskusea, Psorophora (and its three subgenera), Rampamyia, Scutomyia, Stegomyia, Tanakaius, Udaya, Vansomerenis, Verrallina (and subgenera Harbachius and Neomacleaya), Zavortinkius and Zeugnomyia. In addition, the monophyly of Tewarius, newly added to the data set, is confirmed. Heizmannia (Mattinglyia) and Verrallina (Verrallina) were found to be paraphyletic with respect to Heizmannia (Heizmannia) and Verrallina (Neomacleaya), respectively. The analyses were repeated with the 14 characters derived from length measurements treated as ordered. Although somewhat different patterns of relationships among the genera and subgenera were found, all were recovered as monophyletic taxa with the sole exception of Dendroskusea stat. nov. Fifteen additional genera, three of which are new, and 12 additional subgenera, 11 of which are new, are proposed for monophyletic clades, and a few lineages represented by a single species, based on tree topology, the principle of equivalent rank, branch support and the number and nature of the characters that support the branches. Acartomyia stat. nov., Aedimorphus stat. nov., Cancraedes stat. nov., Cornetius stat. nov., Geoskusea stat. nov., Levua stat. nov., Lewnielsenius stat. nov., Rhinoskusea stat. nov. and Sallumia stat. nov., which were previously recognized as subgenera of various genera, are elevated to generic status. Catageiomyia stat. nov. and Polyleptiomyia stat. nov. are resurrected from synonymy with Aedimorphus, and Catatassomyia stat.
no. and Dendroskusea stat. nov. are resurrected from synonymy with Diceromyia. Bifidistylus gen. nov. (type species: Aedes lamborni Edwards) and Elpeytonius gen. nov. (type species: Ochlerotatus apicoannulatus Edwards) are described as new for species previously included in Aedes (Aedimorphus), and Petermattinglyius gen. nov. (type species: Aedes iyengari Edwards) and Pe. (Aglaonotus) subgen. nov. (type species: Aedes whartoni Mattingly) are described as new for species previously included in Aedes (Diceromyia). Four additional subgenera are recognized for species of Ochlerotatus, including Oc. (Culicada) stat. nov. (type species: Culex canadensis Theobald), Oc. (Juppius) subgen. nov. (type species: Grabhamia caballa Theobald), Oc. (Lepidokeneon) subgen. nov. (type species: Aedes spilotus Marks) and Oc. (Woodius) subgen. nov. (type species: Aedes intrudens Dyar), and seven are proposed for species of Stegomyia: St. (Actinothrix) subgen. nov. (type species: Stegomyia edwardsi Barraud), St. (Bohartius) subgen. nov. (type species: Aedes pandani Stone), St. (Heteraspidion) subgen. nov. (type species: Stegomyia annandalei Theobald), St. (Huangmyia) subgen. nov. (type species: Stegomyia mediopunctata Theobald), St. (Mukwaya) subgen. nov. (type species: Stegomyia simpsoni Theobald), St. (Xyele) subgen. nov. (type species: Stegomyia desmotes Giles) and St. (Zoromorphus) subgen. nov. (type species: Aedes futunae Belkin). Due to the unavailability of specimens for study, many species of Stegomyia are without subgeneric placement. As is usual with generic-level groups of Aedini, the newly recognized genera and subgenera are polythetic taxa that are diagnosed by unique combinations of characters. The analysis corroborates the previous observation that 'Oc. (Protomacleaya)' is a polyphyletic assemblage of species.

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

AB We used an optimization modeling framework to devise spatially explicit habitat acquisition and restoration strategies for 19 remnant-dependent butterflies in a rapidly urbanizing county in the Chicago area. We first identified the smallest sets of protected sites that would contain at least one population of each species, and two populations for species present in multiple sites. We then identified undeveloped properties contiguous with these sites whose acquisition would further enhance conditions for focal species. Next, we considered parcels in the surrounding landscape that could potentially be acquired and restored to provide additional habitat. Assuming that the conservation value of additional habitats would increase with their proximity to protected sites, we examined tradeoffs between distance to sites and the cost of acquisition and restoration. The tradeoff curves generated by the model represented choices among sets of reserves that varied widely with regard to cost and distance. Among the non-dominated solutions for a given total area budget, the best solutions depend on the decision makers preference for these two objectives. Sets along the frontier of these curves differed in total cost due to the variation in the number of wetlands per parcel, the number and cost of parcels that must be acquired to provide sufficient habitat, and restoration costs. Several parcels appeared in all solutions and should be prioritized for acquisition. Our general approach is readily adaptable to other locations and planning objectives, but the models would need to be modified to accommodate different target species and their habitat requirements.

AB The effect of different oral rabies vaccine (ORV) bait densities (75, 150, and 300 baits/km(2)) on the seroprevalence of rabies virus neutralizing antibodies (RVNAs) in raccoons (Procyon lotor) was assessed at a 15% seroprevalence difference threshold in rural areas of northeast Ohio. Results (n = 588 raccoons) indicated that seropositivity for RVNAs was associated with both bait density and bait campaign frequency. Associations were not detected for raccoon gender, age, or macro-habitat. The odds of being seropositive were greater for raccoons originating from 300 bait/km(2) treatment areas relative to those coming from the 75 bait/km(2) areas (odds ratio [OR] = 4.4, probability [P] < 0.001, 95% confidence interval [Cl] = 2.4-7.9), while accounting for cumulative ORV campaigns. No statistical advantage in seroprevalence was detected when comparing 150-75 baits/km(2). These results indicate that a relatively extreme bait density when evenly distributed may be necessary to obtain a significant increase in seroprevalence. Higher bait densities may be more appropriate and less costly to address focused outbreaks than labor intensive trap-vaccinate-release and local population reduction campaigns. Finally, dramatic increases in seroprevalence of RVNA were not observed in raccoons between sequential, semi-annual campaigns, yet cumulative ORV campaigns were associated with gradual increases in seroprevalence.

AB Oral vaccination is an important part of wildlife rabies control programs. Currently, the vaccinia-rabies glycoprotein recombinant virus is the only oral rabies vaccine licensed in the United States. and it is not effective in skunks. In the current study, captive raccoons and skunks were used to evaluate a vaccine developed by incorporating the rabies virus glycoprotein gene into a canine adenovirus serotype 2 vector (CAV2-RVG). Seven of 7 raccoons orally vaccinated with CAV2-RVG developed virus neutralizing antibodies and survived lethal challenge. Five of 5 and 6 of 6 skunks in 2 experimental groups receiving 10-fold different dilutions of CAV2-RVG developed neutralizing antibodies and survived challenge. The results of this preliminary study suggest that CAV2-RVG stimulates protective immunity against rabies in raccoons and skunks. Published by Elsevier Ltd.

AB Parenteral vaccination campaigns are integral to the elimination of canine rabies. To maximize herd immunity in dogs, immunocontraception provided at the time of rabies vaccination should reduce fecundity and dog abundance. GonaCon (TM) has been used successfully as an immunocontraceptive in a variety of mammals, and by inference, the dog would be an ideal candidate for testing. As an initial step in evaluating a combination-vaccination program, we assessed the effects of GonaCon (TM) on rabies virus neutralizing antibody production in dogs after administration of a veterinary rabies vaccine. Eighteen feral/free ranging dogs were included in this initial study: six were given GonaCon (TM) only, six were given rabies vaccination only, and six received GonaCon (TM) and rabies vaccination. Antibody levels were evaluated over 82 days. The use of the immunocontraceptive GonaCon (TM) did not affect the ability of dogs to seroconvert in response to the rabies vaccine. Thus, GonaCon (TM) provides a potential immunocontraceptive for use in combination with rabies vaccine to increase herd immunity and address dog population over abundance to better manage rabies.

AB Due to the action of o-quinones formed via polyphenol oxidase,conserved red clover (Trifolium pratense L.) contains abundant rumen undegradable protein (RUP), but inadequate rumen degradable protein (RDP) for dairy cattle. This study examined how forage management influences RDP, RUP, crude protein (CP) and fiber fractions in red clover silage and dry matter (DM) yields during the first full production year. In 2003 and 2006, red clover was cut early on 7 June or late on 14 June with two similar to 40 d regrowth cuts. For comparison, alfalfa (Medicago, sativa L) was cut early on 26 May with three similar to 32 d regrowth cuts or late using the same schedule as early cut red clover. After ensiling at 370 g/kg DM, CP and fiber were fractionated according to the Cornell Net Carbohydrate and Protein System (CNCPS). RDP and RUP were calculated from CNCPS fractions or estimated by a more convenient Streptomyces griseus protease procedure, which gave highly related (R(2) >= 0.95) estimates of CP degradability. Early cutting of red clover favorably decreased RUP, neutral detergent fiber (NDF), and acid detergent fiber (ADF) and increased RDP and CP in the first two harvests. Regression analyses indicated desirable levels of RDP (> 150 g/kg DM) and NDF (similar to 400 g/kg DM) could be obtained by harvesting red clover at a mean stage weight maturity of 2.0 at first cut, 3.0 at second cut, and 3.5-4.0 at third cut. Averaged across harvest schedules, red clover had lower RDP, CP and ADF, higher RUP, and similar NDF compared to alfalfa. Total DM yields of red clover and alfalfa were not influenced by harvest schedule. Time of establishment had little effect on silage quality, but it did influence total DM yields; April vs. August seeding depressed red clover yields (12.3 t/ha vs. 13.1 t/ha) but enhanced alfalfa yields (12.5 t/ha vs. 11.9 t/ha) during the first full production year. Overall, these results suggest protein utilization and performance of dairy cattle could be moderately improved without sacrificing DM yield by taking a very early first cutting of red clover followed by regrowth cuttings made at progressively later maturities.

AB Background: To enhance capabilities for genomic analyses in rainbow trout, such as genomic selection, a large suite of polymorphic markers that are amenable to high-throughput genotyping protocols must be identified. Expressed Sequence Tags (ESTs) have been used for single nucleotide polymorphism (SNP) discovery in salmonids. In those strategies, the salmonid semi-tetraploid genomes often led to assemblies of paralogous sequences and therefore resulted in a high rate of false positive SNP identification. Sequencing genomic DNA using primers identified from ESTs proved to be an effective but time consuming methodology of SNP identification in rainbow trout, therefore not suitable for high throughput SNP discovery. In this study, we employed a high-throughput strategy that used pyrosequencing technology to generate data from a reduced representation library constructed with genomic DNA pooled from 96 unrelated rainbow trout that represent the National Center for Cool and Cold Water Aquaculture (NCCCWA) broodstock population.
Results: The reduced representation library consisted of 440 bp fragments resulting from complete digestion with the restriction enzyme HaeIII; sequencing produced 2,000,000 reads providing an average 6 fold coverage of the estimated 150,000 unique genomic restriction fragments (300,000 fragment ends). Three independent data analyses identified 22,022 to 47,128 putative SNPs on 13,140 to 24,627 independent contigs. A set of 384 putative SNPs, randomly selected from the sets produced by the three analyses were genotyped on individual fish to determine the validation rate of putative SNPs among analyses, distinguish apparent SNPs that actually represent paralogous loci in the tetraploid genome, examine Mendelian segregation, and place the validated SNPs on the rainbow trout linkage map. Approximately 48% (183) of the putative SNPs were validated; 167 markers were successfully incorporated into the rainbow trout linkage map. In addition, 2% of the sequences from the validated markers were associated with rainbow trout transcripts.
Conclusion: The use of reduced representation libraries and pyrosequencing technology proved to be an effective strategy for the discovery of a high number of putative SNPs in rainbow trout; however, modifications to the technique to decrease the false discovery rate resulting from the evolutionary recent genome duplication would be desirable.

AB Prunella vulgaris has been used therapeutically for inflammation-related conditions for centuries, but systematic studies of its anti-inflammatory activity are lacking and no specific active components have been identified. In this study, water and ethanol extracts of four P. vulgaris accessions were applied to RAW 264.7 mouse macrophages, and the ethanol extracts significantly inhibited lipopolysaccharide (LPS)-stimulated prostaglandin E2 (PGE2) and nitric oxide (NO) production at 30 mu g/mL without affecting cell viability. Extracts from different accessions of P. vulgaris were screened for anti-inflammatory activity to identify accessions with the greatest activity. The inhibition of PGE2 and NO production by selected extracts was dose-dependent, with significant effects seen at concentrations as low as 10 mu g/mL. Fractionation of ethanol extracts from the active accession, Ames 27664, suggested fractions 3 and 5 as possible major contributors to the overall activity. Rosmarinic acid (RA) content in P. vulgaris was found to independently inhibit inflammatory response, but it only partially explained the extracts' activity. LPS-induced cyclooxygenase-2 (COX-2) and nitric oxide synthase (NOS) protein expression were both attenuated by P. vulgaris ethanol extracts, whereas RA inhibited only COX-2 expression.

AB Oscillatoria perornata, a cyanobacterium (blue-green alga), common in catfish production ponds in the southeastern United States, produces the monoterpene 2-methylisoborneol (MIB), which is absorbed into catfish flesh and imparts a "musty" taste, rendering them unpalatable and unmarketable. Algicides that are currently in the commercial market to control O. perornata have broad-spectrum toxicity toward other beneficial phytoplankton, such as the green alga Selenastrum capricornutum, as well as low biodegradability. As part of our continuing efforts to search for natural-product-based algicides, the ethyl acetate extract of the roots of Swinglea glutinosa was investigated. This report describes isolation and structure elucidation of one novel coumarin, two known coumarins, and nine acridone alkaloids from S. glutinosa root extracts and the evaluation of these compounds for algicidal activity against O. perornata.

AB Mango (Mangifera indica L.) is a tropical fruit grown worldwide with excellent nutritional value and widely attributed health-promoting properties. Extensive studies have been made of the high concentrations of phenolic antioxidants in mango peels, seeds, and leaves, yet less is known about the phenolic antioxidants of mango fruit pulp. Five varieties of mangoes from four countries were evaluated with multiple harvests over 1 year to compare the P-carotene, ascorbic acid, and total phenolic contents and antioxidant capacities of the fruit pulp and to compare the phenolic profiles of the individual varieties. To minimize ripeness variability, only soft fruit (0.5-1 N compression) with a minimum of 10% soluble solids were used for these measurements. Ascorbic acid ranged from 11 to 134 mg/100 g of pulp puree, and beta-carotene varied from 5 to 30 mg/kg among the five varieties. Total phenolic content ranged from 19.5 to 166.7 mg of gallic acid equivalents (GAE)/100 g of puree. The varieties Tommy Atkins, Kent, Keitt, and Haden had similar total phenolic contents, averaging 31.2 +/- 7.8 mg GAE/100 g of puree, whereas the variety Ataulfo contained substantially higher values. Similar trends were observed in the DPPH radical scavenging activities among the five varieties. In contrast, the country of origin and harvest dates had far less influence on these parameters. Ataulfo mangoes contained significantly higher amounts of mangiferin and ellagic acid than the other four varieties. Large fruit-to-fruit variations in the concentrations of these compounds occurred within sets of mangoes of the same cultivar with the same harvest location and date.

ID FRAGMENTS
AB Several studies have suggested that the emulsification properties associated with pectin obtained from sugar beet (Beta vulgaris) are due to the presence of a protein-pectin complex. Nevertheless, the identity of the protein has remained elusive. Pectin, extracted from sugar beet pulp by microwave-assisted extraction, and a commercial sample were both subjected to protease digestion with trypsin. The resulting peptides were separated from the pectin solution by ultrafiltration using a 3 kDa molecular weight cutoff (MWCO) membrane and analyzed using matrix-assisted laser desorption ionization with tandem time-of-flight mass spectrometry. The partial sequences derived from the mass spectrometry analyses of the resulting tryptic peptides are found to be highly consistent with extensin protein matched from the B. vulgaris Genetic Index database and also correspond to previously reported extensin peptides found in sugar beet cell suspension cultures. Further attempts were made to disassociate the protein from pectin using 1 M NaCl and a 100 kDa MWCO membrane; however, no peptides were observed following trypsin digestion of the permeate solution. This evidence suggests the existence of a complex between the pectin and extensin that is not due to ionic interactions. Trypsin digestion of commercial sugar beet pectin also produced the peptide profile observed with the microwave-assisted extracted pectin sample. Atomic force microscopy established that the number of rod-like elements decreased following protease treatment compared to the untreated sample.

AB Channel water balances of contiguous reaches along streams represent a poorly understood scale of stream-subsurface interaction. We measured reach water balances along a headwater stream in Montana, United States, during summer base flow recessions. Reach water balances were estimated from series of tracer tests in 13 consecutive reaches delineated evenly along a 2.6 km valley segment. For each reach, we estimated net change in discharge, gross hydrologic loss, and gross hydrologic gain from tracer dilution and mass recovery. Four series of tracer tests were performed during relatively high, intermediate, and low base flow conditions. The relative distribution of channel water along the stream was strongly related to a transition in valley structure, with a general increase in gross losses through the recession. During tracer tests at intermediate and low flows, there were frequent substantial losses of tracer mass (>10%) that could not be explained by net loss in flow over the reach, indicating that many of the study reaches were concurrently losing and gaining water. For example, one reach with little net change in discharge exchanged nearly 20% of upstream flow with gains and losses along the reach. These substantial bidirectional exchanges suggest that some channel interactions with subsurface flow paths were not measurable by net change in flow or transient storage of recovered tracer. Understanding bidirectional channel water balances in stream reaches along valleys is critical to an accurate assessment of stream solute fate and transport and to a full assessment of exchanges between the stream channel and surrounding subsurface.

AB Understanding ecosystem-atmosphere carbon exchanges in dryland environments has been more challenging than in mesic environments, likely due to more pronounced nonlinear responses of ecosystem processes to environmental variation. To better understand diurnal to interannual variation in gross primary productivity (GPP) variability, we coupled continuous eddy-covariance derived whole ecosystem gas exchange measurements with an ecophysiologic model based on fundamental principles of diffusion, mass balance, reaction kinetics, and biochemical regulation of photosynthesis. We evaluated the coupled data-model system to describe and understand the dynamics of 3 years of growing season GPP from a riparian grassland and woodland in southern Arizona. The data-model fusion procedure skillfully reproduced the majority of daily variation GPP throughout three growing seasons. While meteorology was similar between sites, the woodland site had consistently higher GPP rates and lower variability at daily and interannual timescales relative to the grassland site. We examined the causes of this variation using a new state factor model analysis that partitioned GPP variation into four factors: meteorology, physiology, leaf area, and water supply. The largest proportion of GPP variation was associated with physiological differences. The woodland showed a greater sensitivity than the grassland to water supply, while the grassland showed a greater sensitivity to leaf area. These differences are consistent with hypotheses of woody species using resistance mechanisms, stomatal regulation, and grassland species using resilience mechanisms, leaf area regulation, in avoiding water stress and have implications for future GPP sensitivity to climate variability following wood-grass transitions.

AB Array-based comparative genomics hybridization (aCGH) has gained prevalence as an effective technique for measuring structural variations in the genome. Copy-number variations (CNVs) form a large source of genomic structural variation, but it is not known whether phenotypic differences between intra-species groups, such as divergent human populations, or breeds of a domestic animal, can be attributed to CNVs. Several computational methods have been proposed to improve the detection of CNVs from array CGH data, but few population studies have used CGH data for identification of intra-species differences. In this paper we propose a novel method of genome-wide comparison and classification using CGH data that condenses whole genome information, aimed at quantification of intra-species variations and discovery of shared ancestry. Our strategy included smoothing CGH data using an appropriate denoising algorithm, extracting features via wavelets, quantifying the information via wavelet power spectrum and hierarchical clustering of the resultant profile. To evaluate the classification efficiency of our method, we used simulated data sets. We applied it to aCGH data from human and bovine individuals and showed that it successfully detects existing intra-specific variations with additional evolutionary implications.

AB Background: Lettuce (Lactuca saliva L.) is susceptible to dieback, a soilborne disease caused by two viruses from the family Tombusviridae. Susceptibility to dieback is widespread in romaine and leaf-type lettuce, while modern iceberg cultivars are resistant to this disease. Resistance in iceberg cultivars is conferred by Tvr1 - a single, dominant gene that provides durable resistance. This study describes fine mapping of the resistance gene, analysis of nucleotide polymorphism and linkage disequilibrium in the Tvr1 region, and development of molecular markers for marker-assisted selection.
Results: A combination of classical linkage mapping and association mapping allowed us to pinpoint the location of the Tvr1 resistance gene on chromosomal linkage group 2. Nine molecular markers, based on expressed sequence tags (EST), were closely linked to Tvr1 in the mapping population, developed from crosses between resistant (Salinas and Salinas 88) and susceptible (Valmaine) cultivars. Sequencing of these markers from a set of 68 cultivars revealed a relatively high level of nucleotide polymorphism (= 6.7 x 10(-3)) and extensive linkage disequilibrium (r(2) = 0.124 at 8 cM) in this region. However, the extent of linkage disequilibrium was affected by population structure and the values were substantially larger when the analysis was performed only for romaine (r(2) = 0.247) and crisphead (r(2) = 0.345) accessions. The association mapping approach revealed that one of the nine markers (Cntg10192) in the Tvr1 region matched exactly with resistant and susceptible phenotypes when tested on a set of 200 L. sativa accessions from all horticultural types of lettuce. The marker-trait association was also confirmed on two accessions of Lactuca serriola - a wild relative of cultivated lettuce. The combination of three single-nucleotide polymorphisms (SNPs) at the Cntg10192 marker identified four haplotypes. Three of the haplotypes were associated with resistance and one of them was always associated with susceptibility to the disease.
Conclusion: We have successfully applied high-resolution DNA melting (HRM) analysis to distinguish all four haplotypes of the Cntg10192 marker in a single analysis. Marker-assisted selection for dieback resistance with HRM is now an integral part of our breeding program that is focused on the development of improved lettuce cultivars.

AB The fisher (Martes pennanti) is a forest mustelid endemic to North America that has experienced range reductions in Pacific states that have led to their listing under the Endangered Species Act as warranted but precluded by higher priorities. The viability of the southern Sierra Nevada fisher population is of particular concern due to its reduced historical range, isolated nature, and low genetic variability. We located resting structures of radio-collared fishers in the southern Sierra Nevada and compared resting and available habitat to examine selection for specific features of resting sites. Resting structures provide protection from predators and unfavorable weather and are believed to be the most limiting habitat element across fisher home ranges. Resting structures were found primarily in live trees (76%) and snags (15%). Trees used by fishers for resting were among the largest available and frequently had mistletoe infestations. Ponderosa pines (Pinus ponderosa) were used more often than expected and incense cedars (Calocedrus decurrens) less than expected. Snags were also large and in fairly advanced stages of decay. Habitat at fisher resting sites had higher canopy cover, greater basal area of snags and hardwoods, and smaller and more variable tree sizes compared to random sites. Resting sites were also found on steeper slopes and closer to streams. Canopy cover was consistently the most important variable distinguishing rest and random sites. In western North America, fishers are generally associated with late-successional forests, but changes in these forests due to logging and fire suppression have resulted in a transition to forest stands characterized by fewer large trees and more small stems. These conditions are consistent with our finding that the large rest structures were surrounded by smaller than average trees. Management practices that support the growth and retention of greater numbers of large trees and snags, while maintaining a minimum of 61% (based on moosehorn) or 56% (generated via Forest Vegetation Simulator) canopy cover and a complex horizontal and vertical forest structure, can improve and provide for future fisher habitat.

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

INFESTATIONS
AB Background: The cattle tick Rhipicephalus (Boophilus) microplus is involved in the transmission of the protozoan Babesia bovis, the etiological agent of bovine babesiosis. Interactions between ticks and protozoa are poorly understood and the investigation of tick genes that affect tick fitness and protozoan infection can set the stage for dissecting the molecular interactions between the two species.
Results: In this study, RNA interference was used to silence R. microplus genes that had been previously shown to be up-regulated in response to B. bovis infection. The silencing of a putative immunophilin gene (Imnp) in female ticks fed on a calf acutely infected with B. bovis decreased the hatching rate and survival of larval progeny. Interestingly, Imnp was up-regulated significantly in ovaries of R. microplus in response to B. bovis infection and its silencing in female ticks significantly increased the infection rate of the protozoan in larval progeny. The results also showed that the silencing of a putative Kunitz-type serine protease inhibitor (Spi) gene and a putative lipocalin (Lpc) gene decreased the fitness of R. microplus females, but had no significant effect on the infection rate of B. bovis in larval progeny.
Conclusion: The silencing of the Imnp, Spi or Lpc genes decreased the fitness of R. microplus females fed on a calf during acute B. bovis infection. The Imnp gene data suggest that this putative immunophilin gene is involved in the defense system of R. microplus against B. bovis and may play a role in controlling the protozoan infection in tick ovaries and larval progeny.

AB We report an improved draft nucleotide sequence of the 2.3-gigabase genome of maize, an important crop plant and model for biological research. Over 32,000 genes were predicted, of which 99.8% were placed on reference chromosomes. Nearly 85% of the genome is composed of hundreds of families of transposable elements, dispersed nonuniformly across the genome. These were responsible for the capture and amplification of numerous gene fragments and affect the composition, sizes, and positions of centromeres. We also report on the correlation of methylation-poor regions with Mu transposon insertions and recombination, and copy number variants with insertions and/or deletions, as well as how uneven gene losses between duplicated regions were involved in returning an ancient allotetraploid to a genetically diploid state. These analyses inform and set the stage for further investigations to improve our understanding of the domestication and agricultural improvements of maize.

AB Maize is an important crop species of high genetic diversity. We identified and genotyped several million sequence polymorphisms among 27 diverse maize inbred lines and discovered that the genome was characterized by highly divergent haplotypes and showed 10- to 30-fold variation in recombination rates. Most chromosomes have pericentromeric regions with highly suppressed recombination that appear to have influenced the effectiveness of selection during maize inbred development and may be a major component of heterosis. We found hundreds of selective sweeps and highly differentiated regions that probably contain loci that are key to geographic adaptation. This survey of genetic diversity provides a foundation for uniting breeding efforts across the world and for dissecting complex traits through genome-wide association studies.

AB Bacteria-mediated acquisition of atmospheric N(2) serves as a critical source of nitrogen in terrestrial ecosystems. Here we reveal that symbiotic nitrogen fixation facilitates the cultivation of specialized fungal crops by leaf-cutter ants. By using acetylene reduction and stable isotope experiments, we demonstrated that N(2) fixation occurred in the fungus gardens of eight leaf-cutter ant species and, further, that this fixed nitrogen was incorporated into ant biomass. Symbiotic N(2)-fixing bacteria were consistently isolated from the fungus gardens of 80 leaf-cutter ant colonies collected in Argentina, Costa Rica, and Panama. The discovery of N(2) fixation within the leaf-cutter ant-microbe symbiosis reveals a previously unrecognized nitrogen source in neotropical ecosystems.

AB Milk thistle (Silybum marianum L.) is an excellent source of silymarin used as an antioxidant. Microwave-assisted extraction (MAE) was employed to extract silymarin from milk thistle seeds. The effects of four independents variables in terms of extraction time, temperature, ethanol concentration, and solid-liquid ratio on the silymarin yield were determined and the optimal conditions for silymarin were evaluated by means of response surface methodology. Correlation analysis of the mathematical regression model indicated that a quadratic polynomial model could be employed to characterize MAE process for the silymarin. Response surface plots showed that these independent variables, except for extraction time, and interactions significantly influenced the extraction yield of silymarin. The optimal extraction parameters to obtain the highest silymarin yield were time duration of 60 min, temperature of 112 degrees C, ethanol concentration of 81.5% (v/v), and a solid-liquid ratio of 1:38 (g/mL). The average experimental silymarin yield under the optimum conditions was found to be 56.67 +/- 1.36 mg/g, which agree with the predicted value of 57.40 mg/g. MAE method was applied successfully to extract silymarin from milk thistle seeds. (C) 2009 Elsevier B.V. All rights reserved.

The objective of these experiments was to develop a selection system for producing transgenic soybean somatic embryos without the use of antibiotics such as hygromycin.
Results: When tested against different alternate selection agents our studies show that 0.16 mu g/mL glufosinate, 40 mg/L isopropylamine-glyphosate, 0.5 mg/mL (S-(2 aminoethyl)-L-cysteine) (AEC) and the acetolactate synthase (ALS) inhibitors Exceed(R) and Synchrony(R) both at 150 mu g/mL inhibited soybean somatic embryo growth. Even at the concentration of 2 mg/mL, lysine+threonine (LT) were poor selection agents. The use of AEC may be preferable since it is a natural compound. Unlike the plant enzyme, dihydrodipicolinate synthase (DHPS) from E. coli is not feed-back inhibited by physiological concentrations of lysine. The dapA gene which codes for E. coli DHPS was expressed in soybean somatic embryos under the control of the CaMV 35S promoter. Following introduction of the construct into embryogenic tissue of soybean, transgenic events were recovered by incubating the tissue in liquid medium containing AEC at a concentration of 5 mM. Only transgenic soybeans were able to grow at this concentration of AEC; no escapes were observed.
Conclusion: Genetically engineered soybeans expressing a lysine insensitive DHPS gene can be selected with the non-antibiotic selection agent AEC. We also report here the inhibitory effects of glufosinate, (isopropylamine-glyphosate) (Roundup(R)), AEC and the ALS inhibitors Exceed(R) and Synchrony(R) against different tissues of soybean

AB Background: Parthenium argentatum (guayule) is an industrial crop that produces latex, which was recently commercialized as a source of latex rubber safe for people with Type I latex allergy. The complete plastid genome of P. argentatum was sequenced. The sequence provides important information useful for genetic engineering strategies. Comparison to the sequences of plastid genomes from three other members of the Asteraceae, Lactuca sativa, Guitozia abyssinica and Helianthus annuus revealed details of the evolution of the four genomes. Chloroplast-specific DNA barcodes were developed for identification of Parthenium species and lines.
Results: The complete plastid genome of P. argentatum is 152,803 bp. Based on the overall comparison of individual protein coding genes with those in L. sativa, G. abyssinica and H. annuus, we demonstrate that the P. argentatum chloroplast genome sequence is most closely related to that of H. annuus. Similar to chloroplast genomes in G. abyssinica, L. sativa and H. annuus, the plastid genome of P. argentatum has a large 23 kb inversion with a smaller 3.4 kb inversion, within the large inversion. Using the matK and psbA-trnH spacer chloroplast DNA barcodes, three of the four Parthenium species tested, P. tomentosum, P. hysterophorus and P. schottii, can be differentiated from P. argentatum. In addition, we identified lines within P. argentatum.
Conclusion: The genome sequence of the P. argentatum chloroplast will enrich the sequence resources of plastid genomes in commercial crops. The availability of the complete plastid genome sequence may facilitate transformation efficiency by using the precise sequence of endogenous flanking sequences and regulatory elements in chloroplast transformation vectors. The DNA barcoding study forms the foundation for genetic identification of commercially significant lines of P. argentatum that are important for producing latex.

AB Sugar beet pulp (SBP) was chemically modified with the goal to utilize this method for the preparation of water-soluble polysaccharides. Yields of the trimethylammoniumhydroxypropylated (TMAHP) polysaccharide fractions prepared under vacuum in absence of NaOH or KOH, as well as their molar masses, were higher than those obtained when the samples were only extracted with hydroxide at ambient pressure. The hydroxypropylsulfonated (HPS) fractions extracted at ambient pressure with NaOH had higher yields and molar mass than the TMAHP fractions extracted under vacuum with KOH. introduction of both ion-exchange groups in one step under vacuum with NaOH gave better yields than with KOH, but smaller than for the solely sulfonated sample. The molar masses of chemically modified fractions were smaller than those extracted only with alkali or water. According to the monosaccharide composition all the fractions are mixtures of arabinogalactans and rhamnogalacturonoans. (C) 2009 Elsevier Ltd. All rights reserved.

AB Molecular dynamics simulations using AMB06C, an in-house carbohydrate force field, (NPT ensembles, 1 atm) were carried out on a periodic cell that contained a cyclic 240 glucose residue amylose fragment (c-DP-240) and TIP3P water molecules. Molecular conformation and movement of the amylose fragment and water molecules at different temperatures were examined. The periodic cell volume, density, and potential energy were determined at temperatures above and below the glass transition temperature (T(g)) in 25 K increments. The amorphous cell is constructed through successive dynamic equilibration steps at temperatures above the assumed T(g) value and the temperature successively lowered until several temperature points were obtained below T(g). Molecular dynamics simulations were continued for at least 500 ps or until the volume drift stopped and remained constant for several hundred picoseconds. The T(g) values were found by noting the discontinuity in slope of the volume (V), potential energy (PE), or density (rho) versus 1/T. The changes in flexibility and motion of the amylose chain as well as differences in self diffusion coefficients of water molecules are described. The final average T(g) value found (316 K) is in agreement with experimental values, i.e. similar to 320 K. Published by Elsevier Ltd.

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

AB A new methodology for establishing the spatial representativeness of tower albedo measurements that are routinely used in validation of satellite retrievals from global land surface albedo and reflectance anisotropy products is presented. This method brings together knowledge of the intrinsic biophysical properties of a measurement site, and the surrounding landscape to produce a number of geostatistical attributes that describe the overall variability, spatial extent, strength of the spatial correlation, and spatial structure of surface albedo patterns at separate seasonal periods throughout the year. Variogram functions extracted from Enhanced Thematic Mapper Plus (ETM+) retrievals of surface albedo using multiple spatial and temporal thresholds were used to assess the degree to which a given point (tower) measurement is able to capture the intrinsic variability of the immediate landscape extending to a satellite pixel. A validation scheme was implemented over a wide range of forested landscapes, looking at both deciduous and coniferous sites, from tropical to boreal ecosystems. The experiment focused on comparisons between tower measurements of surface albedo acquired at local solar noon and matching retrievals from the MODerate Resolution Imaging Spectroradiometer (MODIS) (Collection V005) Bidirectional Reflectance Distribution Function (BRDF)/albedo algorithm. Assessments over a select group of field stations with comparable landscape features and daily retrieval scenarios further demonstrate the ability of this technique to identify measurement sites that contain the intrinsic spatial and seasonal features of surface albedo over sufficiently large enough footprints for use in modeling and remote sensing studies. This approach, therefore, improves our understanding of product uncertainty both in terms of the representativeness of the field data and its relationship to the larger satellite pixel.

AB Accurate estimation of live and dead biomass in forested ecosystems is important for studies of carbon dynamics, biodiversity, wildfire behavior, and for forest management. Lidar remote sensing has been used successfully to estimate live biomass, but studies focusing on dead biomass are rare. We used lidar data, in conjunction with field measurements from 58 plots to distinguish between and map standing live and dead tree biomass in the mixed coniferous forest of the North Rim of Grand Canyon National Park, USA. Lidar intensity and canopy volume were key variables for estimating live biomass, whereas for dead biomass, lidar intensity alone was critical for accurate estimation. Regression estimates of both live and dead biomass ranged between 0 and 600 Mg ha(-1), with means of 195.08 Mg ha(-1) and 65.73 Mg ha(-1), respectively. Cross validation with field data resulted in correlation coefficients for predicted vs. observed of 0.85 for live biomass (RMSE = 50 Mg ha(-1) and %RMSE (RMSE as a percent of the mean) = 26). For dead biomass, correlation was 0.79, RMSE was 42 Mg ha(-1), and %RMSE was 63. Biomass maps revealed interesting patterns of live and dead standing tree biomass. Live biomass was highest in the ponderosa pine zone, and decreased from south to north through the mixed conifer and spruce-fir forest zones. Dead biomass exhibited a background range of values in these mature forests from zero to 100 Mg ha(-1), with lower values in locations having higher live biomass. In areas with high dead biomass values, live biomass was near zero. These areas were associated with recent wildfires, as indicated by fire maps derived from the Monitoring Trends in Burn Severity Project (MTBS). Combining our dead biomass maps with the MTBS maps, we demonstrated the complementary power of these two datasets, revealing that MTBS burn intensity class can be described quantitatively in terms of dead biomass. Assuming a background range of dead biomass up to 100 Mg ha(-1), it is possible to estimate and map the contribution to the standing dead tree biomass pool associated with recent wildfire.

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

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

AB Large amounts of the major storage proteins, beta-conglycinin and glycinin, in soybean (Glycine max) seeds hinder the isolation and characterization of less abundant seed proteins. We investigated whether isopropanol extraction could facilitate resolution of the low abundant proteins, different from the main storage protein fractions, in one-dimensional polyacrylamide gel electrophoresis (1D-PAGE) and two-dimensional polyacrylamide gel electrophoresis (2D-PAGE). 1D-PAGE of proteins extracted by different concentrations (10%, 20%, 30%, 40%, 50%, 60%, 70% and 80%) of isopropanol showed that greater than 30% isopropanol was suitable for preferential enrichment of low abundant proteins. Analysis of 2D-PAGE showed that proteins which were less abundant or absent by the conventional extraction procedure were clearly seen in the 40% isopropanol extracts. Increasing isopropanol concentration above 40% resulted in a decrease in the number of less abundant protein spots. We have identified a total of 107 protein spots using matrix-assisted laser desorption/ionization time of flight mass spectrophotometry (MALDI-TOF-MS) and liquid chromatography-mass spectrometry (LC-MS/MS). Our results suggest that extraction of soybean seed powder with 40% isopropanol enriches lower abundance proteins and is a suitable method for 2D-PAGE separation and identification. This methodology could potentially allow the extraction and characterization of low abundant proteins of other legume seeds containing highly abundant storage proteins.

AB Understanding the influence of storm events on nitrate (NO3-) dynamics is important for efficiently managing NO3- pollution. In this study, five sites representing a downstream progression of forested uplands underlain by resistant sandstone to karst lowlands with agricultural, urban and mixed land-use were established in Spring Creek, a 201 km(2) mixed land-use watershed in central Pennsylvania. USA. At each site, stream water was monitored during six storm events in 2005 to assess changes in stable isotopes of NO3- (delta N-15-NO3- and delta O-18-NO3-) and water (delta O-18-H2O) from baseflow to peakflow. Peakflow fractions of event NO3- and event water were then computed using two-component mixing models to elucidate NO3- flow pathway differences among the five sites. For the forested upland site, storm size appeared to affect NO3- sources and flow pathways. During small storms (<35 mm, rainfall), greater event NO3- fractions than event water fractions indicated the prevalence of atmospheric NO3- source contributions at peakflow. During larger storms (>35 mm rainfall), event NO3- fractions were less than event water fractions at peakflow suggesting that NO3- was flushed from stored sources via shallow subsurface flow pathways. For the urbanized site, wash-off of atmospheric NO3- was an important NO3- source at peakflow, especially during short-duration storms where event water contributions indicated the prevalence of overland flow. In the karst lowlands, very low fractions of event water and even lower fractions of event NO3- at peakflow suggested the dominance of ground water flow pathways during storms. These ground water flow pathways likely flushed stored NO3- sources into the stream, while deep soils in the karst lowlands also may have promoted NO3- assimilation. The results of this study illustrated how NO3- isotopes and delta O-18-H2O could be combined to show key differences in water and NO3- delivery between forested uplands, karst valleys and fully urbanized watersheds.

AB This research studied the characteristics of poly(acrylamide) and methylcellulose (PAAm-MC) hydrogels as a novel adsorbent material for removal of pesticide paraquat, from aqueous solution, with potential applications in curbing environmental risk from such herbicides. PAAm-MC hydrogels with different acrylamide (AAm) and MC concentrations were prepared by a free-radical polymerization method. The capability of the hydrogels in removing paraquat dichloride from aqueous solution was determined using UV-Vis analysis. The scanning electron microscopy method was used to study the morphological properties of the hydrogels, and swelling degree (Q) of the hydrogels was also measured. The entrapped MC in PAAm chains provoked significant changes in morphological, hydrophilic, and adsorption properties of the PAAm-MC hydrogels. The adsorption capacity of hydrogels was strongly influenced by AAm, MC, and paraquat concentrations with the highest adsorption capacity (q(eq) = 14.3 mg g(-1)) was observed for hydrogels synthesized with 6.0%, AAm with 0.75%, MC swollen in 45.7 mg L(-1) of paraquat Solution. Freundlich model performed better than Langmuir model in describing the adsorption isotherm of PAAm-MC/paraquat system, implying a heterogeneous surface. These results suggest that PAAm-MC hydrogels are potentially viable absorbents for removal of paraquat pesticide from aqueous solution and cleaning water contaminated with dyes, heavy metals, and others pesticides.

AB The bacterium Helicobacter pylori is remarkable for its ability to persist in the human stomach for decades without provoking sterilizing immunity. Since repetitive DNA can facilitate adaptive genomic flexibility via increased recombination, insertion, and deletion, we searched the genomes of two H. pylori strains for nucleotide repeats. We discovered a family of genes with extensive repetitive DNA that we have termed the H. pylori RD gene family. Each gene of this family is composed of a conserved 3' region, a variable mid-region encoding 7 and 11 amino acid repeats, and a 5' region containing one of two possible alleles. Analysis of five complete genome sequences and PCR genotyping of 42 H. pylori strains revealed extensive variation between strains in the number, location, and arrangement of RD genes. Furthermore, examination of multiple strains isolated from a single subject's stomach revealed intrahost variation in repeat number and composition. Despite prior evidence that the protein products of this gene family are expressed at the bacterial cell surface, enzyme-linked immunosorbent assay and immunoblot studies revealed no consistent seroreactivity to a recombinant RD protein by H. pylori-positive hosts. The pattern of repeats uncovered in the RD gene family appears to reflect slipped-strand mispairing or domain duplication, allowing for redundancy and subsequent diversity in genotype and phenotype. This novel family of hypervariable genes with conserved, repetitive, and allelic domains may represent an important locus for understanding H. pylori persistence in its natural host.

AB Numerous metabolism studies have demonstrated that the toxic contaminant 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) is poorly metabolized. A hallmark feature of TCDD exposure is induction of hepatic CYP1A2 and subsequent sequestration leading to high liver-to-fat concentration ratios. This study was initiated to determine whether TCDD was inherently poorly metabolized or unavailable for metabolism because of sequestration to CYP1A2. [H-3]TCDD was administered as a single, oral dose (0.1 and 10 mu g/kg) to 12 male C57BL/6N mice or 12 CYP1A2 (-/-) mice. At 96 h, less than 5% of the dose was eliminated in the urine of all groups, and TCDD detected in urine was bound to mouse major urinary protein (mMUP). Feces were the major elimination pathway (24-31% of dose), and fecal extracts and non-extractables were quantitated by HPLC for metabolites. No great differences in urinary or fecal elimination (% dose) were observed between the high and low dose treatments. TCDD concentrations were the highest in adipose tissue for CYP1A2 knockout mice but in liver for C57BL/6N mice supporting the role of hepatic CYP1A2 in the sequestration of TCDD. Overall metabolism between parental and knockout strains showed no statistical differences at either the high or low doses. The data suggested that metabolism of TCDD is inherently slow, due principally to CYP1A7, and that hepatic CYP1A2 is not an active participant in the metabolism of TCDD in male mice. Rather, CYP1A2 governs the pharmacokinetics of TCDD by making it unavailable for hepatic CYP1A1 through sequestration and attenuating extrahepatic tissue disposition. Published by Elsevier Inc.

AB Ichthyophthirius multifiliis (Ich), a ciliated protozoan parasite of fish, expresses surface antigens (i-antigens), which react with host antibodies that render them immobile. The nucleotide sequence of an i-antigen gene of I. multifiliis strain ARS-6 was deduced. The predicted protein of 47 493 Da is comprised of 460 amino acids (aa's) arranged into five imperfect repeats with periodic cysteine residues with the structure: CX(19)20CX2CX16-27CX2CX20(21)CX3. The N-terminal aa's typify a signal peptide motif while a stretch of C-terminal aa's resemble a glycosyl-phosphatidyl-inositol (GPI)-anchor addition site. The degree of deduced i-antigen aa sequence identity of strain ARS-6 (GenBank accession # ACH87654 and # ACH95659) with other I. multifiliis i-antigen sequences present in GenBank ranges from 99% to 36% identity with 52 kDa i-antigens of I. multifiliis strain G5 (accession #s AAK94941 and AAK01661 respectively). Immunoblot analysis of i-antigens following exposure of I. multifiliis theronts to catfish anti-I. multifiliis immune serum did not show any appreciable alteration in i-antigen expression. The mechanism that regulates i-antigen expression in I. multifiliis remains a puzzling question.

AB Mucin hypersecretion is considered to be one of the most common components of the immune response to gastrointestinal nematode infection. However, investigations have not been conducted in the Cattle-Cooperia oncophora system to verify the findings largely derived from murine models. In this study, we examined the expression of seven mucins and seven enzymes in the mucin biosynthesis pathway involved in O-linked glycosylation in the bovine small intestine including goblet cells enriched using laser capture microdissection during a primary C oncophora infection. At the mRNA level, MUC2 expression was significantly higher in both lamina propria and goblet cells at 28 days post-infection compared to the naive control. MUC5B expression at the mRNA level was also higher in lamina propria at 28 dpi. Expression of MUC1, MUC4, MUC5AC, and MUC6 was extremely low or not detectable in goblet cells, columnar epithelial cells. and lamina propria from both naive control and infected animals. Among the seven enzymes involved in post-translational O-linked glycosylation of mucins, GCNT3, which may represent one of the key rate-limiting steps in mucin biosynthesis. was Lip-regulated in goblet cells, columnar epithelial cells, lamina propria, and gross small intestine tissue during the course of infection. Western blot analysis revealed that MUC2 glycoprotein was strongly induced by infection in both gross small intestine tissue and its mucosal layer In contrast, the higher MUM protein expression was observed only in the mucosal layer. Immunohistochemistry provided further evidence of the mucin glycoprotein production and localization. Our results provided insight into regulation of mucin biosynthesis in various cell types in the bovine small intestine during gastrointestinal nematode infection and will facilitate our understanding of mucins and their role in immune response against parasitic nematodes.

AB Acaricides can be conveyed to ticks via the blood of their hosts. As fruit and kernel extracts from the Meliaceae family, and. in particular the tetranortriterpenoid azadirachtin (AZA) Inhibits tick egg production and embryogenesis in the Ixodidae ticks, we investigated the effects of Neem Azal (R), an extract containing 43% AZA, given as a feed additive to lambs artificially infested with engorging adult Dermacentor vairiabilis ticks. After tick attachment, the lambs were allotted to three dietary treatments: AZA0 (control, n = 10). AZA0.3 (n = 5), and AZA0 6(n = 5), with feed containing 0%, 0.3%, and 0 6% AZA on EM basis, respectively. In half of the AZA0 lambs, ticks were sprayed on day 4 after attachment with an etlianol.water:soap emulsion containing 0.6% AZA (AZA0S) In spite of its very pungent odor, the neem extract was well accepted by all but one lamb No differences were found between treatment groups in liver enzymes in blood, and there was no indication of toxicity. The plasma AZA concentrations after 7 and 14 days of feeding AZA were (4 81 and 4 35 mu g/mL) for the AZA0 6 and (3.32 and 188 mu g/mL) for the AZA0.3 treatments. respectively (P < 0.0001). Treatments were not lethal to ticks, but tick weights at detachment were 0.64. 0.56, 0.48, and 0 37 g for ticks from the AZA0, AZA0.3, AZA0S. and AZA0.6 treatments (P < 0.04), respectively. suggesting that blood AZA impaired blood-feeding The highest mortality rate after detachment was for AZA0.6 (P < 0.09) As AZA affects embryo development and ticks at the molting stages, we expect that following treatments of hosts for longer periods, one-host ticks will be more affected than the three-host tick D vanabilis.

AB Felids are important in the epidemiology of Toxoplasma gondii infection because they are the only hosts that can excrete environmentally resistant oocysts Antibodies to T gondii and Neospora caninum were determined in serum samples from 59 feral cats (Fells silvestris catus) captured in baited traps during authorized predator control campaigns in Majorca, Balearic Islands. Spain Antibodies to T gondii assayed by the mollified agglutination test (MAT) were found in 50 (84.7%) of 59 cats with MAT titers of 1:25 in one cat, 1:200 in four cats. 1:500 in seven cats, 1:1000 in nine cats, and >= 1.2000 in 29 cats. Seroprevalence (MAT, 1.25 or more) was significantly higher in adults (94.6%) than in juveniles (< 6 months old, 40 0%). Seroprevalence to N caninum, assayed by cELISA (VMRD) and confirmed by an indirect fluorescent antibody test, was low (6 8%. 4 of 59). The prevalence of T gondii observed in wild cats in Majorca is one of the highest reported worldwide in this species and the highest observed in Europe to date. The results suggest that feral cats in Majorca have a high rate of T. gondii infection with important implications for public health on the island since the seropositive cats are likely to have already shed T. gondii oocysts in the environment.

AB Toxoplasma gondii is widely distributed in humans and other animals including domestic poultry throughout the world. but little is known of the prevalence of T gondii in chickens and ducks in People's Republic of China. In the present Study, antibodies to T gondii were investigated in 349 domestic ducks (Anus spp.), 361 free-range, and 244 caged chickens (Gallus domesticus) raised in commercial flocks in Southern China's Guangdong Province using the modified agglutination test (MAT) Antibodies to T gondii (MAT titer of 1 5 or higher) were found in 56 (16%) of 349 ducks, 41 (11.4%) of 361 free-range, and 10 (4.1%) of 244 caged chickens. The results indicate soil contamination clue to T gondii oocysts because free-range chickens feed from the ground, and suggest Oat the meat from the domestic poultry may be an important source for human infection by T gondii in People's Republic of China (c) 2009 Elsevier B.V.

AB Previous research has suggested that nitrate-respiring pathogens such as Escherichia coli O157:H7 and Salmonella spp. are susceptible to chlorate salts due to the conversion of chlorate to chlorite by respiratory nitrate reductase. This study was conducted to determine the effect of chlorate on E. coli O157:H7 growth and chlorate biotransformation and to determine whether chlorite is produced in anaerobic culture of E coli O157:H7. Final concentrations of E coli O157:H7 were generally decreased by about 2 log units in incubations containing <= 5 mM chlorate, except when bacteria were pretreated with 10 mM chlorate. [(36)Cl]Chlorate metabolism by pure cultures of E. coli O157:H7 was not measurable above chlorate concentrations of 5 mM, but measurable chlorate reduction occurred in cultures containing 0.5, 1, or 5 mM [(36)Cl]chlorate. Pretreatment of E coli O157:H7 with 5 mM nitrate did not increase the rate of chlorate conversion to chloride, suggesting that nitrate did not induce nitrate reductase isoforms capable of metabolizing chlorate in E coli O157:H7. Pure cultures of E coli O157:H7 preconditioned with 10 mM chlorate had an attenuated ability to transform [(36)Cl]chlorate to [(36)Cl]chloride with measurable chlorate reduction only occurring in 0.5 mM chlorate treatments. The hypothesis that E. coli O157:H7 is sensitive to chlorate by virtue of the reduction of chlorate to chlorite ion (CIO(2)(-)) was supported, but not proven, by the direct measurement of low concentrations of [(36)Cl]CIO(2)(-) in incubation media containing 0.5 mM [(36)Cl]CIO(3)(-). Collectively these results indicate that growth of E. coli O157:H7 in pure culture will be reduced in the presence of 5 mM or greater concentrations of sodium chlorate and that E. coli O157:H7 is capable of producing chlorite ions during the metabolism of chlorate.

AB A surface plasmon resonance (SPR) biosensor screening assay was developed and validated to detect 11 benzimidazole carbamate (BZT) veterinary drug residues in milk. The polyclonal antibody used was raised in sheep against a methyl 5(6)-[(carboxypentyl)-thio]-2-benzimidazole carbamate protein conjugate. A sample preparation procedure was developed using a modified QuEChERS method. BZT residues were extracted from milk using liquid extraction/partition with a dispersive solid phase extraction clean-up step. The assay was validated in accordance with the performance criteria described in 2002/657/EC. The limit of detection of the assay was calculated from the analysis of 20 known negative milk samples to be 2.7 mu g kg(-1). The detection capability (CC beta) of the assay was determined to be 5 mu g kg(-1) for 11 benzimidazole residues and the mean recovery of analytes was in the range 81-116%. A comparison was made between the SPR-biosensor and UPLC-MS/MS analyses of milk samples (n = 26) taken from cows treated different benzimidazole products, demonstrating the SPR-biosensor assay to be fit for purpose.

AB Long-term field experiments are needed to fully realize positive and negative impacts of conservation tillage and poultry litter application. A study was initiated on a Decatur silt loam soil at the Tennessee Valley Research and Extension Center, Belle Mina, AL, USA in 1996 to evaluate cotton (Gossypium hirsutum L.) performance with long-term poultry litter (PL) application under different tillages and to Study the build up of phosphorus (P) With application of PL. Treatments include incomplete factorial combinations of three tillage systems [conventional till (CT), mulch till (MT), and no-till (NT)], two cropping systems [cotton-fallow and cotton-winter rye (Secale cereale L.)], and two nitrogen sources and rates [100 kg N ha(-1) from ammonium nitrate (AN), and 100 and 200 kg N ha(-1) from poultry litter (PL)]. Cotton was rotated with corn (Zea mays L.) every third year. Results from 2003 to 2008 showed that all tillages gave similar cotton lint yields with AN at 100 kg N ha(-1). Application of PL at 100 kg N ha(-1) in NT plots resulted in 12 and 11% yield reductions compared to that of CT and MT, respectively. However, NT plots with higher quantity of PL (200 kg N ha(-1)) gave similar yields to CT and MT at 100 kg N ha(-1). During corn years, higher residual fertility of PL, in terms of grain yields, was observed in NT plots compared to CT and MT. Long-term PL application (100 kg N ha(-1) year(-1)) helped to maintain original soil pH in CT and MT while AN application decreased soil pH. In NT plots, PL at 100 kg N ha(-1) was not sufficient to maintain original soil pH, but 200 kg N ha(-1) maintained original pH. Although not-significant, elevated P levels were observed in all tillages compared to original P levels which indicates possibility of P build up in future with further application of PL. Application of PL at double rate (200 kg N ha(-1)) in NT plots resulted in significant build up of P. Results indicate that NT gives similar yields to CT when received AN. but needs higher rate of PL application to achieve similar yields to CT. (C) 2009 Elsevier B,V. All rights reserved.

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

AB A bioclimate model predicting the presence or absence of aspen, Populus tremuloides, in western USA from climate variables was developed by using the Random Forests classification tree on Forest Inventory data from about 118,000 permanent sample plots. A reasonably parsimonious model used eight predictors to describe aspen's climate profile. Classification errors averaged 4.5%, most of which were errors of commission. The model was driven primarily by three variables: an annual dryness index, the ratio of summer to annual precipitation, and an interaction of growing season precipitation with the summer-winter temperature differential. Projecting the contemporary climate profile into the future climate provided by three General Circulation Models and two scenarios (SRES A2 and either B1 or B2) suggested that the area occupied by the profile should diminish rapidly over the course of the century, 6-41% by the decade surrounding 2030, 40-75% for that surrounding 2060, and 46-94% for 2090. The relevance of the climate profile to understanding climate-based responses is illustrated by relating trends in climate to the recent incidence of sudden aspen dieback that has plagued portions of the aspen distribution. Of the eight variables in the profile, four reached extreme values during 2000-2003, the period immediately preceding the appearance of damage in aerial surveys. (C) 2009 Published by Elsevier B.V.

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

AB The Ecosystem Management Decision Support (EMDS) system has been used by the US Department of Agriculture, Forest Service and Bureaus of the Department of the Interior since 2006 to evaluate wildfire potential across all administrative units in the continental US, and to establish priorities for allocating fuel-treatment budgets. This article discusses an EMDS fuels-treatment decision-support application, agency experiences with the application, and the extent to which it addressed concerns in Congress, and those of the General Accountability Office. EMDS aids the budget allocation process by providing a rational, transparent, and reproducible process that can be clearly communicated to Congressional staff and oversight personnel. However, practical application of this decision-support process was not without challenges, which included missing or suboptimal data, clearly articulated fuels management objectives, and improved understanding (via re-assessing decision logic from prior years) of trade-offs in decision-making.

AB We describe and then model satellite-inferred severe (stand-replacing) fire occurrence relative to topography (elevation, aspect, slope, solar radiation, Heat Load Index, wetness and measures of topographic ruggedness) using data from 114 fires > 40 ha in area that occurred between 1984 and 2004 in the Gila Wilderness and surrounding Gila National Forest. Severe fire occurred more frequently at higher elevations and on north-facing, steep slopes and at locally wet, cool sites, which suggests that moisture limitations on productivity in the southwestern US interact with topography to influence vegetation density and fuel production that in turn influence burn severity. We use the Random Forest algorithm and a stratified random sample of burn severity pixels with corresponding pixels from 15 topographic layers as predictor variables to build an empirical model predicting the probability of occurrence for severe burns across the entire 1.4 million ha study area. Our model correctly classified severity with a classification accuracy of 79.5% when burn severity pixels were classified as severe vs. not severe (two classes). Because our model was derived from data sampled across many fires over a 20-year period, it represents average probability of severe fire occurrence and is unlikely to predict burn severity for individual fire events. However, we believe it has potential as a tool for planning fuel treatment projects, in management of actively burning fires, and for better understanding of landscape-scale burn severity patterns.

AB Understanding the proximate causes of post-fire conifer mortality due to smoldering duff fires is essential to the restoration and management of coniferous forests throughout North America. To better understand duff fire-caused mortality, we investigated tree stress and radial growth following experimental fires in a long-unburned forest on deep sands in northern Florida, USA. We burned basal fuels surrounding 80 mature Pinus palustris Mill. in a randomized experiment comparing the effects of basal burning treatments on stem vascular meristems; surficial roots; root and stem combinations; and a non-smoldering control. We examined the effects of duration of lethal temperatures (>60 degrees C) on subsequent pine radial growth and root non-structural carbohydrates (starch and sugar). Duff and mineral soil temperatures in the experimental fires consistently exceeded 60 degrees C for over an hour following ignition, with lethal temperatures of shorter duration recorded 20 cm below the mineral soil surface. Duff heating was best explained by day-of-burn Oe horizon moisture (P = 0.01), although little variation was explained (R(2) = 0.24). Post-fire changes in latewood radial increment in the year following fires was related to duration of temperatures >60 degrees C 10 cm deep in the mineral soil (P = 0.07), but explained little variability in post-fire growth (R(2) = 0.17). In contrast, changes in non-structural carbohydrate content in coarse roots (2-5 mm diameter) 120 days following burning were more strongly correlated with the duration of lethal heating 5 cm below the mineral soil surface (P = 0.02; R(2) = 0.53). Results from this study implicate the role of mineral soil heating in the post-fire decline of mature longleaf pine following restoration fires in sandy soils. (C) 2009 Elsevier B.V.

AB There has been little examination of the relationship between the stocking of live trees in forests and the associated attributes of dead tree resources which could inform large-scale efforts to estimate and manage deadwood resources. The goal of this study was to examine the relationships between the stocking of standing live trees and attributes of standing dead and downed dead trees using a national inventory of forests in the United States. Results indicated that from the lowest to the highest class of live tree relative stand density, the mean biomass/ha of live trees increased over 2000% while standing dead and downed dead trees biomass/ha increased 295 and 75%, respectively. Correlations between downed deadwood biomass and stand/site attributes increased as live tree stocking increased. The size/density attributes of standing and downed deadwood exhibited no relationship with standing live stocking possibly due to the confounding factors of decay and breakage. This study proposes a conceptual deadwood stocking model with standing live tree stocking as an axis along which deadwood accretion factors (e.g., disturbance, self-thinning, and senescence) and depletion factors (e.g., decay, harvest, and stagnation) ultimately determine deadwood stocking.

AB Background: Nutrigenetics studies the role of genetic variation on interactions between diet and health, aiming to provide more personalized dietary advice. However, replication has been low. Our aim was to study interaction among a functional APOA2 polymorphism, food intake, and body mass index (BMI) in independent populations to replicate findings and to increase their evidence level.
Methods: Cross-sectional, follow-up (20 years), and case-control analyses were undertaken in 3 independent populations. We analyzed gene-diet interactions between the APOA2 -265T>C polymorphism and saturated fat intake on BMI and obesity in 3462 individuals from 3 populations in the United States: the Framingham Offspring Study, (1454 whites), the Genetics of Lipid Lowering Drugs and Diet Network Study (1078 whites), and Boston-Puerto Rican Centers on Population Health and Health Disparities Study (930 Hispanics of Caribbean origin).
Results: Prevalence of the CC genotype in study participants ranged from 10.5% to 16.2%. We identified statistically significant interactions between the APOA2 -265T>C and saturated fat regarding BMI in all 3 populations. Thus, the magnitude of the difference in BMI between the individuals with the CC and TT+TC genotypes differed by saturated fat. A mean increase in BMI of 6.2% (range, 4.3%-7.9%; P=.01) was observed between genotypes with high- (>= 22 g/d) but not with low-saturated fat intake in all studies. Likewise, the CC genotype was significantly associated with higher obesity prevalence in all populations only in the high-saturated fat stratum. Meta-analysis estimations of obesity for individuals with the CC genotype compared with the TT+TC genotype were an odds ratio of 1.84 (95% confidence interval, 1.38-2.47; P < .001) in the high-saturated fat stratum, but no association was detected in the low-saturated fat stratum (odds ratio, 0.81; 95% confidence interval, 0.59-1.11; P=18).
Conclusion: For the first time to our knowledge, a gene-diet interaction influencing BMI and obesity has been strongly and consistently replicated in 3 independent populations.

AB A fast, rigorous method was developed to maximize the extraction efficacy for ten perfluorocarboxylic acids and perfluorooctanesulfonate from waste-water-treatment sludge and to quantitate using liquid chromatography, tandem-mass spectrometry (LC/MS/MS). First, organic solvents were tested for extraction efficiency, including acetonitrile (ACN), methanol (MeOH), isopropanol (IPA), tetrahydrofuran (THF), and 50/50 ACN/MeOH (v/v). Among the extractants tested, 50/50 ACN/MeOH yielded the best results for our combined criteria of extraction efficacy and solvent-handling convenience. Second, chemical pretreatment prior to solvent extraction was tested with sodium hydroxide (NaOH), potassium hydroxide (KOH), hydrochloric acid (HCl), and potassium persulfate (K(2)S(2)O(8)). Pretreatment with NaOH and HCl effectively recovered additional PFCs from the sludge, but KOH and K(2)S(2)O(8) digestion were less effective than no pretreatment. Third, cleanup methods were investigated with solid-phase extraction using HLB (hydrophilic-lipophilic balanced) and WAX (weak-anion exchange) stationary phases, and with ion-pairing. The HLB stationary phase yielded a slight edge over the other two cleanup strategies in terms of recoverable PFCs and chromatographic separation. Finally, the appropriateness of isotopically labeled PFCs for quantitating unlabeled PFCs using isotopic dilution in complex sludge extracts was evaluated by comparison to results obtained with the standard-addition method. A National Institute of Standards and Technology (NIST) domestic sludge (CRM 2781) was analyzed using our finalized method and compared with previously reported results. (C) 2009 Elsevier B.V.

AB Background: Given its sequenced genome and efficient systemic RNA interference response, the red flour beetle Tribolium castaneum is a model organism well suited for reverse genetics. Even so, there is a pressing need for forward genetic analysis to escape the bias inherent in candidate gene approaches.
Results: To produce easy-to-maintain insertional mutations and to obtain fluorescent marker lines to aid phenotypic analysis, we undertook a large-scale transposon mutagenesis screen. In this screen, we produced more than 6,500 new piggyBac insertions. Of these, 421 proved to be recessive lethal, 75 were semi-lethal, and eight indicated recessive sterility, while 505 showed new enhancer-trap patterns. Insertion junctions were determined for 403 lines and often appeared to be located within transcription units. Insertion sites appeared to be randomly distributed throughout the genome, with the exception of a preference for reinsertion near the donor site.
Conclusion: A large collection of enhancer-trap and embryonic lethal beetle lines has been made available to the research community and will foster investigations into diverse fields of insect biology, pest control, and evolution. Because the genetic elements used in this screen are species-nonspecific, and because the crossing scheme does not depend on balancer chromosomes, the methods presented herein should be broadly applicable for many insect species.

AB We prepared starch films by jet-cooking aqueous dispersions of high-amylose starch and then allowing the jet-cooked dispersions to air-dry on Teflon surfaces. When the starch films were immersed in 1% solutions of polyethylene (PE) in 1-dodecanol, dodecane, and xylene at 120 degrees C and the solutions were allowed to slowly cool, PE precipitated from the solutions and adsorbed onto the starch film surfaces. Fourier transform infrared spectroscopy was used to estimate the micrograms of PE adsorbed per square centimeter of starch film. PE was preferentially adsorbed onto the film side that was in contact with the Teflon surface during drying. The amount of PE adsorbed ranged from about 8 to 45 mu g/cm(2) and depended upon the solvent used and the final temperature of the cooled solution. Scanning electron microscopy of the starch film surfaces showed discontinuous networks of adsorbed PE on the Teflon side and widely spaced nodules of adsorbed PE on the air side. NMR analysis showed that the PE adsorbed onto the starch surface was more linear and/or had a higher molecular weight than the starting PE. Possible reasons for the selective adsorption of PE onto the Teflon side of the starch film surface are discussed. (C) 2009 Wiley Periodicals, Inc.(dagger) J Appl Polym Sci 114: 1840-1847, 2009

AB Foot and mouth disease (FMD) is a highly infectious and economically devastating disease of livestock. Although vaccines, available since the early 1900s, have been instrumental in eradicating FMD from parts of the world, the disease still affects millions of animals around the globe and remains the main sanitary barrier to the commerce of animals and animal products. Currently available inactivated antigen vaccines applied intramuscularly to individual animals, confer serotype and subtype specific protection in 1-2 weeks but fail to induce long-term protective immunity. Among the limitations of this vaccine are potential virus escape from the production facility, short shelf life of formulated product, short duration of immunity and requirement of dozens of antigens to address viral antigenic diversity. Here we review novel vaccine approaches that address some of these limitations. Basic research and the combination of reliable animal inoculation models, reverse genetics and computational biology tools will allow the rational design of safe and effective FMD vaccines. These vaccines should address not only the needs of FMD-free countries but also allow the progressive global control and eradication of this devastating disease. Published by Elsevier Ltd.

AB Background: Since the emergence of H5N1 high pathogenicity (HP) avian influenza virus (AIV) in Asia, numerous efforts worldwide have focused on elucidating the relative roles of wild birds and domestic poultry movement in virus dissemination. In accordance with this a surveillance program for AIV in wild birds was conducted in Mongolia from 2005-2007. An important feature of Mongolia is that there is little domestic poultry production in the country, therefore AIV detection in wild birds would not likely be from spill-over from domestic poultry.
Results: During 2005-2007 2,139 specimens representing 4,077 individual birds of 45 species were tested for AIV by real time RT-PCR (rRT-PCR) and/or virus isolation. Bird age and health status were recorded. Ninety rRT-PCR AIV positive samples representing 89 individual birds of 19 species including 9 low pathogenicity (LP) AIVs were isolated from 6 species. A Bar-headed goose (Anser indicus), a Whooper swan (Cygnus cygnus) and 2 Ruddy shelducks (Tadorna ferruginea) were positive for H12N3 LP AIV. H16N3 and H13N6 viruses were isolated from Black-headed gulls (Larus ridibundus). A Red-crested pochard (Rhodonessa rufina) and 2 Mongolian gulls (Larus vagae mongolicus) were positive for H3N6 and H16N6 LP AIV, respectively. Full genomes of each virus isolate were sequenced and analyzed phylogenetically and were most closely related to recent European and Asian wild bird lineage AIVs and individual genes loosely grouped by year. Reassortment occurred within and among different years and subtypes.
Conclusion: Detection and/or isolation of AIV infection in numerous wild bird species, including 2 which have not been previously described as hosts, reinforces the wide host range of AIV within avian species. Reassortment complexity within the genomes indicate the introduction of new AIV strains into wild bird populations annually, however there is enough over-lap of infection for reassortment to occur. Further work is needed to clarify how AIV is maintained in these wild bird reservoirs.

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

AB The temperature of the Earth is rising, and is highly likely to continue to do so for the foreseeable future. The study of the effects of sustained heating on the ecosystems of the world is necessary so that we might predict and respond to coming changes on both large and small spatial scales. To this end, ecosystem warming studies have been performed for more than 20 years using a variety of methods. These warming methods fall into two general categories: active and passive. Active warming methods include heat-resistance cables, infrared (IR) lamps and active field chambers. Passive warming methods include nighttime warming and passive field chambers. An extensive literature review was performed and all ecosystem warming study sites were compiled into a master list. These studies were divided by latitude and precipitation, as well as the method type used and response variables investigated. The goals of this study were to identify: ( I) the most generally applicable, inexpensive and effective heating methods; and (2) areas of the world that are understudied or have been studied using only limited warming methods. It was found that the most generally applicable method, and the one that is most true to climate change predictions, is IR heating lamp installation. The least expensive method is passive chambers. The extreme lower and upper latitudes have been investigated least with ecosystem warming methods, and for the upper-mid-latitudes (60-80 degrees) there have been limited studies published using methods other than passive chambers. Ecosystem warming method limitations and recommendations are discussed. (C) 2009 Elsevier B.V. All rights reserved.

AB One year of continuous data from two eddy-flux towers established along an elevation gradient in coastal Shanghai was analyzed to evaluate the tidal effect on carbon flux (F-c) over an estuarine wetland. The measured wavelet spectra and cospectra of F-c and other environmental factors demonstrated that the dynamics of F-c at both sites exhibited a tidal-driven pattern with obvious characteristics at scales between 10 and 20 days (256-512-h). Environmental factors exerted major controls on the carbon balance at finer temporal scales F-c was more sensitive to tides at the low-elevation site than at the high-elevation site. Overall, the mean nighttime F-c during spring tides was lower than that during neap, tides, indicating suppressed ecosystem respiration under inundation. Larger differences were observed at the low-elevation site due to longer inundation durations. In contrast, daytime F-c was more variable since plants reacted differently in different growth periods and under different tidal elevations. The amplitudes of diurnal F-c during tidal periods were larger than those reported for other wetland types, implying a great potential for future carbon sequestration. Whilst tides would also transport organic matter to nearby estuaries and hence may incur carbon emission in the receiving ecosystems. Thus, further study on lateral carbon transport is required to investigate the tidal effect on the carbon sink/source role of the wetland. (C) 2009 Elsevier B.V. All rights reserved.

AB The integration of remotely sensed data into models of evapotranspiration (ET) facilitates the estimation of water consumption across agricultural regions. To estimate regional ET, two basic types of remote sensing approaches have been successfully applied. The first approach computes a surface energy balance using the radiometric surface temperature for estimating the sensible heat flux (H), and obtaining ET as a residual of the energy balance. This paper compares the performance of three different surface energy balance algorithms: an empirical one-source energy balance model; a one-source model calibrated using inverse modeling of ET extremes (namely ET = 0 and ET at potential) which are assumed to exist within the satellite scene; and a two-source (soil + vegetation) energy balance model. The second approach uses vegetation indices derived from canopy reflectance data to estimate basal crop coefficients that can be used to convert reference ET to actual crop ET. This approach requires local meteorological and soil data to maintain a water balance in the root zone of the crop. Output from these models was compared to sensible and latent heat fluxes measured during the soil moisture-atmosphere coupling experiment (SMACEX) conducted over rain-fed corn and soybean crops in central Iowa. The root mean square differences (RMSD) of the estimation of instantaneous latent and heat fluxes were less than 50 W m(-2) for the three energy balance models. The two-source energy balance model gave the lowest RMSD (30 W m(-2)) and highest r(2) values in comparison with measured fluxes. In addition, three schemes were applied for upscaling instantaneous flux estimates from the energy balance models (at the time of satellite overpass) to daily integrated ET, including conservation of evaporative fraction and fraction of reference ET. For all energy balance models, an adjusted evaporative fraction approach produced the lowest RMSDs in daily ET of 0.4-0.6 mm d(-1). The reflectance-based crop coefficient model yielded RMSD values of 0.4 mm d(-1), but tended to significantly overestimate ET from corn during a prolonged drydown period. Crop stress can be directly detected using radiometric surface temperature, but ET modeling approaches-based solely on vegetation indices will not be sensitive to stress until there is actual reduction in biomass or changes in canopy geometry.

AB Biophysical models intended for routine applications at a range of scales should attempt to balance the competing demands of generality and simplicity and be capable of realistically simulating the response of CO2 and energy fluxes to environmental and physiological forcings. At the same time they must remain computationally inexpensive and sufficiently simple to be effectively parameterized at the scale of application. This study investigates the utility of two modeling strategies for quantifying coupled land surface fluxes of carbon and water, which differ distinctly in their description Of CO2 assimilation processes. 'Bottom-up' models of land-atmosphere carbon exchange are based on detailed mechanistic descriptions of leaf-level photosynthetic processes scaled to the canopy whereas 'top-down' scaling approaches neglect the behavior of individual leaves and consider the canopy response to its environment in bulk. Effective intercomparisons of a light-use-efficiency (LUE)-based model of canopy conductance and a mechanistic model of leaf photosynthesis-stomatal response that employs a 'two-leaf' scaling strategy are facilitated by embedding both canopy sub-models in the Atmosphere-Land Exchange (ALEX) surface energy balance model. Water and carbon flux simulations are evaluated across time scales of hours, days, seasons and years for a variety of natural and agricultural ecosystems, using micrometeorological data from several AmeriFlux sites across the U.S. While both modeling paradigms reproduced observed magnitudes and variances of carbon and water vapor exchange on hourly and daily timescales with acceptable accuracy, the simpler LUE-based model often performed better than the more detailed scaled-leaf model, which has many adjustable species-specific model parameters. Actual light-use efficiencies vary significantly in response to changing environmental conditions and the success of LUE-based modeling frameworks rely on their ability to realistically respond to changes in light environment, atmospheric humidity, CO2 concentration and a desiccating environment.

AB Soil respiration (R-s) is a combination of autotrophic and heterotrophic respiration, but it is often modeled as a single efflux process, influenced by environmental variables similarly across all time scales. Continued progress in understanding sources of variation in soil CO2 efflux will require development of R-s models that incorporate environmental influences at multiple time scales. Coherence analysis, which requires high temporal frequency data on R-s and related environmental variables, permits examination of covariation between R-s and the factors that influence it at varying temporal frequencies, thus isolating the factors important at each time scale. Automated R-s measurements, along with air, soil temperature and moisture were collected at half hour intervals at a temperate forest at Harvard Forest, MA in 2003 and a boreal transition forest at the Howland Forest, ME in 2005. As in other temperate and boreal forests, seasonal variation in R-s was strongly correlated with soil temperature. The organic and mineral layer water contents were significantly related to R-s at synoptic time scales of 2-3 days to weeks, representing the wetting and drying of the soils as weather patterns move across the region. Post-wetting pulses of R-s were correlated with the amount of precipitation and the magnitude of the change from pre-wet-up moisture content to peak moisture content of the organic horizon during the precipitation events. Although soil temperature at 8-10 cm depth and R-s showed strong coherence at a 24-h interval, calculated diel Q(10) values for R-s were unreasonably high (6-74) during all months for the evergreen forest and during the growing season for the deciduous forest, suggesting that other factors that covary with soil temperature, such as canopy assimilatory processes, may also influence the diel amplitude of R-s. Lower diel Q(10) values were obtained based on soil temperature measured at shallower depths or with air temperature, but the fit was poorer and a lag was needed to improve the fit (peak R-s followed peak air temperature by several hours), suggesting a role for delayed substrate supply from aboveground processes to affect diel patterns of R-s. High frequency automated R-s datasets afford the opportunity to disentangle the temporal scales at which environmental factors, such as seasonal temperature and phenology, synoptic weather events and soil moisture, and diel variation in temperature and photosynthesis, affect soil respiration processes.

AB The Pecorans (higher ruminants) are believed to have rapidly speciated in the Mid-Eocene, resulting in five distinct extant families: Antilocapridae, Giraffidae, Moschidae, Cervidae, and Bovidae. Due to the rapid radiation, the Pecoran phylogeny has proven difficult to resolve, and 11 of the 15 possible rooted phylogenies describing ancestral relationships among the Antilocapridae, Giraffidae, Cervidae, and Bovidae have each been argued as representations of the true phylogeny. Here we demonstrate that a genome-wide single nucleotide polymorphism (SNP) genotyping platform designed for one species can be used to genotype ancient DNA from an extinct species and DNA from species diverged up to 29 million years ago and that the produced genotypes can be used to resolve the phylogeny for this rapidly radiated infraorder. We used a high-throughput assay with 54,693 SNP loci developed for Bos taurus taurus to rapidly genotype 678 individuals representing 61 Pecoran species. We produced a highly resolved phylogeny for this diverse group based upon 40,843 genome-wide SNP, which is five times as many informative characters as have previously been analyzed. We also establish a method to amplify and screen genomic information from extinct species, and place Bison priscus within the Bovidae. The quality of genotype calls and the placement of samples within a well-supported phylogeny may provide an important test for validating the fidelity and integrity of ancient samples. Finally, we constructed a phylogenomic network to accurately describe the relationships between 48 cattle breeds and facilitate inferences concerning the history of domestication and breed formation.

AB Patterns of scissile bond twisting have been found in crystal structures of glycoside hydrolases (GHs) that are complexed with substrates and inhibitors. To estimate the increased potential energy in the substrates that results from this twisting, we have plotted torsion angles for the scissile bonds on hybrid Quantum Mechanics:: Molecular Mechanics energy surfaces. Eight Such maps were constructed, including one for alpha-maltose and three for different forms of methyl alpha-acarviosinide to provide energies for twisting of alpha-(1,4) glycosidic bonds. Maps were also made for beta-thiocellobiose and for three beta-cellobiose conformers having different glycon ring shapes to model distortions of beta-(1,4) glycosidic bonds. Different GH families twist scissile glycosidic bonds differently, increasing their potential energies from 0.5 to 9.5 kcal/mol. In general, the direction of twisting of the glycosidic bond away from the conformation of lowest intramolecular energy correlates with the position (syn or anti) of the proton donor with respect to the glycon's ring oxygen atom. This correlation suggests that glycosidic bond distortion is important for the optimal orientation of one of the glycosidic oxygen lone pairs toward the enzyme's proton donor. (C) 2009 Elsevier Ltd.

AB Eighteen empirical force fields and the semi-empirical quantum method PM3CARB-1 were compared for studying beta-cellobiose, alpha-maltose, and alpha-galabiose [alpha-D-Galp-(1 -> 4)-alpha-D-Galp]. For each disaccharide, the energies of 54 conformers with differing hydroxymethyl, hydroxyl, and glycosidic linkage orientations were minimized by the different methods, some at two dielectric constants. By comparing these results and the available crystal structure data and/or higher level density functional theory results, it was concluded that the newer parameterizations for force fields (GROMOS, GLYCAM06, OPLS-2005 and CSFF) give results that are reasonably similar to each other, whereas the older parameterizations for Amber, CHARM or OPLS were more divergent. However, MM3, an older force field, gave energy and geometry values comparable to those of the newer parameterizations, but with less sensitivity to dielectric constant values. These systems worked better than MM2 variants, which were still acceptable. PM3CARB-1 also gave adequate results in terms of linkage and exocyclic torsion angles. GROMOS, GLYCAM06, and MM3 appear to be the best choices, closely followed by MM4, CSFF, and OPLS-2005. With GLYCAM06 and to a lesser extent, CSFF, and OPLS-2005, a number of the conformers that were stable with MM3 changed to other forms. (C) 2009 Elsevier Ltd. All rights reserved.

AB Megalota Diakonoff, previously known from the Indoaustralian Region ( India, Sri Lanka, New Guinea, and Australia), Madagascar, and Africa, is reported from the Neotropics for the first time. Three previously described New World species (i.e., Megalota submicans (Walsingham), n. comb.; M. delphinosema ( Walsingham), n. comb.; and M. plenana ( Walker), n. comb.) were concealed within incorrect generic assignments or as "unplaced" species (i.e., lacking contemporary generic assignments). Twenty-one new species are described and illustrated: M. synchysis (TL: Venezuela), M. peruviana (Peru), M. aquilonaris ( Mexico), M. vulgaris ( Costa Rica), M. cacaulana ( Brazil), M. macrosocia ( Ecuador), M. ochreoapex ( Costa Rica), M. spinulosa ( Costa Rica), M. simpliciana ( Costa Rica), M. jamaicana ( Jamaica), M. ricana ( Costa Rica), M. ceratovalva ( Venezuela), M. bicolorana ( Costa Rica), M. longisetana ( Costa Rica), M. deceptana ( Costa Rica), M. crassana ( Costa Rica), M. gutierrezi ( Costa Rica), M. chamelana ( Mexico), M. beckeri ( Brazil), M. flintana ( Brazil), and M. pastranai ( Argentina). Males of the genus are characterized by three distinctive features of the genitalia: the uncus consists of a pair of greatly expanded, flattened, variably round or square lobes, densely covered with spines and setae; the valvae are narrow with an elongate, apically spined process arising from the base of the costa; and the juxta is membranous with a narrowly sclerotized U- or J-shaped posterior edge. Five species have been reared from Croton spp. ( Euphorbiaceae) in Costa Rica, and this is consistent with a single record of this host for an Australian species of Megalota.

DE Biological invasions; Buprestidae; insect dispersal; invasive forest
pest
AB Emerald ash borer Agrilus planipennis Fairmaire (Coleoptera: Buprestidae) is an invasive forest insect pest threatening more than 8 billion ash (Fraxinus spp.) trees in North America. Development of effective survey methods and strategies to slow the spread of A. planipennis requires an understanding of dispersal, particularly in recently established satellite populations.
We assessed the dispersal of A. planipennis beetles over a single generation at two sites by intensively sampling ash trees at known distances from infested ash logs, the point source of the infestations. Larval density was recorded from more than 100 trees at each site.
Density of A. planipennis larvae by distance for one site was fit to the Ricker function, inverse power function, and the negative exponential function using a maximum likelihood approach. The prediction of the best model, a negative exponential function, was compared with the results from both sites.
The present study demonstrates that larval densities rapidly declined with distance, and that most larvae (88.9 and 90.3%) were on trees within 100 m of the emergence point of the adults at each site. The larval distribution pattern observed at both sites was adequately described by the negative exponential function.

AB The U.S. dairy industry is undergoing rapid structural change, evolving from a structure including many small farmers in the Upper Midwest and Northeast to one that includes very large farms in new production regions. Small farms are struggling to retain competitiveness via improved management and low-input systems. Using data from USDA's Agricultural Resource Management Survey, we determine the extent of U.S. conventional and pasture-based milk production during 2003-2007, and estimate net returns, scale efficiency, and technical efficiency associated with the systems across different operation sizes. We compare the financial performance of small conventional and pasture-based producers with one another and with large-scale producers. A stochastic production frontier is used to analyze performance over the period for conventional and pasture technologies identified using a binomial logit model. Large conventional farms generally outperformed smaller farms using most economic measures-technical efficiency, various profitability measures, and returns to scale.

AB Disposal of saline drainage water is a significant problem for irrigated agriculture. One proposal is to recycle drainage water to irrigate salt tolerant crops until the volume has been reduced sufficiently to enable final disposal by evaporation. Part of this concept requires in situ crop water reuse from shallow groundwater: and data is needed to quantify the potential use of groundwater by alternative crops. A column lysimeter study was initiated to determine the potential crop water use from shallow groundwater by alfalfa as a function of groundwater quality and depth to groundwater. The results demonstrated that up to 50% of the crop water use could be met from shallow groundwater (< 1.2 m) with an electrical conductivity less than 4 dS/m, and that the potential crop water use from deeper groundwater (2 m) increased over the years. The columns with high salinity (>4 dS/m) in the shallow groundwater experienced increased salinity in the soil profile with time, which resulted in reduced crop water use from shallow groundwater. Yields decreased with time as the groundwater salinity increased and periodic leaching will be required for in situ use to be a sustainable practice. Statistical analysis of crop yield demonstrated that there was significant use of groundwater with an EC of 6 dS/rn for a few years. Published by Elsevier B.V.

AB Agriculture contributes 40-60% of the total annual N(2)O emissions to the atmosphere. Development of management practices to reduce these emissions would have a significant impact on greenhouse gas levels. Non-leguminous cover crops are efficient scavengers of residual soil NO(3), thereby reducing leaching losses. However, the effect of a grass cover crop on N(2)O emissions from soil receiving liquid swine manure has not been evaluated. This study investigated: (i) the temporal patterns of N(2)O emissions following addition of swine manure slurry in a laboratory setting under fluctuating soil moisture regimes; (ii) assessed the potential of a rye (Secale cereale L.) cover crop to decrease N(2)O emissions under these conditions: and (iii) quantified field N(2)O emissions in response to either spring applied urea ammonium nitrate (UAN) or different rates of fall-applied liquid swine manure, in the presence or absence of a rye/oat winter cover crop. Laboratory experiments investigating cover crop effects N(2)O emissions were performed in a controlled environment chamber programmed fora 14 h light period, 18 degrees C day temperature, and 15 degrees C night temperature. Treatments with or without a living rye cover crop were treated with either: (i) no manure: (ii) a phosphorus-based manure application rate (low manure): or (iii) a nitrogen-based manure application rate (high manure). We observed a significant reduction in N(2)O emissions in the presence of the rye cover crop. Field experiments were performed on a fine-loamy soil in Central Iowa from October 12, 2005 to October 2, 2006. We observed no significant effect of the cover crop on cumulative N(2)O emissions in the field. The primary factor influencing N(2)O emission was N application rate, regardless of form or timing. The response of N(2)O emission to N additions was non-linear, with progressively more N(2)O emitted with increasing N application. These results indicate that while cover crops have the potential to reduce N(2)O emissions, N application rate may be the overriding factor. Published by Elsevier B.V.

AB Hibiscus sabdariffa is a common ingredient found in blended herbal teas, and beverages made from the dried calyces of this plant are popular worldwide. In vitro studies have shown that H. sabdariffa has antioxidant properties and, in animal models of hypertension, extracts of this plant lower blood pressure. Its anti-hypertensive effects have also been examined in a limited number of human intervention trials. The mechanisms of action of hibiscus may be related to the vasorelaxant, diuretic, and angiotensin converting enzyme (ACE) inhibitor activities of its polyphenolic constituents. Further studies, including properly controlled clinical trials, are essential to fully substantiate the blood pressure-lowering effects of H. sabdariffa.

AB Recently in the state of Tlaxcala, Mexico, the "witches' broom syndrome" (proliferation of shoots and reduction of internodes) was observed in amaranth (Amaranthus hypochondriacus L.). This symptomatology in the field is uniformly distributed in the plantation rather than randomly or in patches, and the most severe damage is in the panicle which contains the seeds, generating considerable losses in the harvest. Therefore, the objective of the present study was to determine the presence of phytoplasmas in plants with symptoms of witches' broom syndrome and in seeds from diseased plants. In all of the samples that were processed an associated phytoplasma was found pertaining to the group 16Sr III, according to the results of the comparison of the patterns generated with enzymes of restriction of the products amplified by PCR. The sequences of the products obtained presented similarity of 98% with the phylogenic group 16Sr III Candidatus Phytoplasma pruni.

AB Windblown soil particle abrasion negatively impacts millions of hectares of crops annually. The goal of this study was to examine the effects of wind and wind blown sand abrasion damage on cotton (Gossypium hirsutum L.) seedling biomass partitioning to leaves, stems, and roots. Seedlings of three cotton cultivars were exposed to no wind (untreated controls) or sand abrasive flux densities of 0, 0.1, 0.25,0.35, and 0.5 g cm(-1) width s(-1) at a wind velocity of 13.4 m s(-1) in a suction-type laboratory wind runnel. Plants were destructively sampled at the time of the sand abrasion treatment and at approximately 2 and 4 wk after exposure. These three sampling dates provided two time intervals for assessing the amount of plant damage and regrowth using classical growth analysis. With increasing sand, abrasive flux density, whole plant, leaf, stem, and root biomass, as well as leaf area, were all reduced in both harvest intervals (P <= 0.05). Net assimilation rate (NAR) accounted for 96 and 75% of the variability in relative growth rate (RGR) in the first and second harvest intervals, respectively, with small but significant differences in leaf area ratio (LAR). Increasing plant damage caused by sand abrasion treatment resulted in preferential biomass partitioning to the damaged stems rather than roots during the first harvest interval, while a much more stable allometric allocation of biomass among plant organs was observed in the second harvest interval.

AB Understanding the effects of management practices on soil properties is necessary because soil properties are directly related to the capacity of soil to function. Soil physical, chemical and biological properties were determined after 3 yr in three cropping sequences [continuous cotton (Gossypium hirsutum L.) (CCC), cotton-corn (Zea mays L.)-cotton (CMC), and corn-cotton-cotton (MCC) each at four broiler litter fertilization rates (0, 4.5, 9, and 13.4 Mg ha(-1)) to a soil depth of 15 cm on a Catalpa silty clay loam soil in Verona, MS. Inorganic N fertilizer was applied at the rate of 123 kg ha(-1) yr(-1) to cotton and 180 kg ha(-1) yr(-1) to corn. Averaged across crop sequences, broiler litter application significantly increased soil nutrient concentrations, microbial biomass C (MBC), total porosity, and aggregate stability (AS). The inclusion of corn into rotation with cotton increased soil MBC, AS, and reduced bulk density (D(b)). Application of broiler litter at rate greater than 9 Mg ha(-1) to CCC resulted in increasing NO(3)-N concentration at the lower 30-cm depth and P accumulation by fourfold at the 0- to 5-cm depth. Rotating cotton with corn in this study improved soil quality parameters and decreased NO(3)-N and P accumulation at the soil surface by approximately 24 and 20%, respectively. Hence, corn is sown in rotation with cotton in Mississippi, the Mississippian cotton industry could potentially improve soil organic carbon, nutrient cycling, and soil quality if broiler litter is used as the nutrient source.

AB Bahiagrass (Paspalum notatum Flugge) cultivars are valued for their persistence under grazing and low management inputs. However, they are daylength-sensitive and have minimal cool-season production, resulting in high winter feeding costs in forage-based livestock systems. New germplasm is less daylength-sensitive, possesses greater cold tolerance, and is more productive during the cool season, but its persistence under defoliation is unknown. A field experiment quantified cover and persistence-related responses of photoperiod-sensitive bahiagrass (diploids 'Pensacola' and 'Tifton 9' and tetraploids 'Argentine' and Tifton 7) and a less photoperiod-sensitive, cold-adapted (PCA) diploid bahiagrass (Cycle 4) at two stubble heights (4 and 8 cm) and two harvest frequencies (7 and 21 d). Argentine cover was unaffected by defoliation treatments, but harvesting every 7 d to 4 cm for 3 yr resulted in <40% cover for both Tifton 9 and Cycle 4. Averaging over defoliation treatments, stem base mass of Pensacola and Argentine was 60% greater than Cycle 4. At 4- and 8-cm stubble heights, the advantage was 86 and 41%, respectively. When defoliated every 7 d, Pensacola and Argentine stein base mass was 125% greater than Cycle 4, while the difference was 23% for the 21-d treatment. Similar but less-pronounced responses were observed for N and total nonstructural carbohydrate (TNC) content of stem base and root + rhizome fractions. Defoliation management of PCA Cycle 4 is more critical than for Pensacola and Argentine bahiagrass, and longer regrowth intervals and taller residual heights may be required to ensure its persistence.

AB The use of crop rotation systems involving winter-annual grazing can help peanut (Arachis hypogaea L.) producers increase profitability, although winter-annual grazing could result in excessive soil compaction, which can severely limit yields. We conducted a 3-yr field study on a Dothan loamy sand in southeastern Alabama to develop a conservation tillage system for integrating peanut with winter-annual grazing of stocker cattle under dryland conditions. Winter-annual forages and tillage systems were evaluated in a strip-plot design, where winter forages were oat (Avena sativa L.) and annual ryegrass (Lolium mutiflorum L.). Tillage systems included moldboard and chisel plowing, and combinations of noninversion deep tillage (none, in-row subsoil, or paratill) with/without disking. We evaluated soil water content, peanut leaf stomatal conductance, plant density, peanut yield, peanut net return, and total system annual net return. Peanut following oat increased soil water extraction (15%), stands (12%), and yields (21%) compared with peanut following ryegrass. Strict no-till resulted in the lowest yields (2.29 Mg ha(-1), 42% less than the mean) and noninversion deep tillage (especially in-row subsoil) was required to maximize water use and yields with conservation tillage. Net return from annual grazing ($185 ha(-1), USD) represented 40% of the total return for the best treatment (no-tillage with in-row subsoil following oat = $462 ha(-1)). Integrating winter-annual grazing in this region using noninversion deep tillage following oat in a conservation tillage system can benefit peanut growers, allowing extra income without sacrificing peanut yields.

ID RESPIRATION; FOREST; EFFLUX; ROOTS
AB Recent advances in sensor technology provide a robust capability for continuous measurement of soil gases. The performance of solid-state CO2 sensors (Model GMM220 series, Vaisala, Inc., Helsinki, Finland) was evaluated in laboratory, greenhouse, and irrigated winter wheat (Triticum aestivum L.). In ambient CO2 concentration, the GMM222 sensor averaged 427 +/- 8.3 mu L L-1. Under variable CO2 concentrations, the sensor was slightly lower than concentrations measured with an infrared gas analyzer (IRGA). In greenhouse pots planted with triticale (Triticale hexaploide Lart.) and an agricultural field of irrigated winter wheat, soil CO2 concentration exceeded the 10,000 mu L L-1 limit of the GMM222. Alternatively, the GMM221 sensor, designed to measure between 0 and 20,000 showed soil CO2 concentrations were between 14,000 and 16,000 mu L L-1. The GMM222 accurately measures real-time soil CO2 concentrations under field conditions that were within the sensor detection limit. However, periods of high biological soil activity require the GMM221 sensor with a higher detection limit.

Plant biomass, leaf area, chlorophyll content, reflectance, and enzyme expression (transcriptome analysis) were measured at V-12. Grain and stover yields were measured with grain analyzed for (13)C isotopic discrimination (A) and N concentration. At V-12, 60% shade plants had increased chlorophyll and reduced leaf area and height compared to full sun plants. In the 2x treatment, plants had 11% less chlorophyll than 1x plants with leaf area and height similar to 60% shade plants. At harvest, plants in the 2x treatment were smaller, had increased water and N use efficiency, and an 11% per hectare yield increase compared with the 1x unstressed treatment. Per-plant yields from 60% shade and 2x treatments were 50% less than 1x unstressed treatment. Yield reduction in shaded plants was attributed to light stress. Lower yield in the 2x treatment was attributed to a population-density induced 20% decrease in the red/near-infrared (NIR) ratio,which resulted in downregulation of C(4) carbon metabolism enzymes (phosphoenolpyruvate carboxykinase, phosphoenolpyruvate carboxylase, and pyruvate orthophosphate dikinase). Although the net impact of high plant density and shade stress on per-plant yield were similar, the stress compensation mechanisms differed.

ID DRIP IRRIGATION; CROP YIELD; WATER-USE; MANAGEMENT; EFFICIENCY;
SCHEDULES; DESIGN
AB Soil water budgets are essential in determining the proper timing and amount of irrigation. Organic fertilizers can be substituted for commercial fertilizers; however, information is sparse on the interaction of irrigation management and nutrient source on cucumber (Cucumis sativus L.) production. This study evaluated nutrient source and irrigation management on growth and yield of cucumber grown in the arid area of Egypt. A field experiment was conducted using cucumber grown in northern Egypt at Shibin El-Kom in 2006 and 2007 to evaluate water use and fertilizer rate and type. Three irrigation deficits and seven fertilization types were arranged in a randomized split-plot design with irrigation rates as main plots and fertilizer treatments within irrigation rates. Irrigation treatments were a ratio of crop evapotranspiration (ET) as: 1.0 ET, 0.84 ET, and 0.64 ET. Fertilizer treatments were applied at the recommended rate of N either as a commercial fertilizer or with organic manure. Chlorophyll a and b, leaf area index, and yield were greatest with the lowest ratios of male to female flowers when adequate water and high N were used (1.0 ET with chicken manure at 7 Mg/ha). Seasonal water use was 498 and 471 mm for 1.0 ET in 2006 and 2007 plantings over the 125 d growing season, respectively. The yield reduction coefficient averaged 0.77. An optimal scheduling was statistically developed based on crop response in deficit irrigation to achieve maximum yield for different uniformity coefficient variation values. Cucumber performance was significantly affected by both irrigation and nutrient deficiencies.

EMERGENCE; FALL GROWTH; SOIL-WATER; MODEL; MANAGEMENT; TILLAGE; DATE
AB Adoption of reduced tillage practices have been driven by the need to enhance soil quality, minimize field labor time, and scale up farm size. However, concerns about increased reliance on herbicides and demand for organically grown foods call for adoption of production practices that can reduce both tillage and herbicide use. This research study assessed the influence of planting and termination dates on mechanical cover crop control efficacy to limit tillage and herbicide use using a roller/crimper. A thermal-based phenological model using growing degree days (GDD; base 4.4 degrees C) was developed to predict cereal rye (Secale cereale L.) growth stage. Mechanical control of cereal rye increased as rye matured. Variations in cereal rye cultivar growth rates were observed; however, they responded similarly to rolling when terminated at the same growth stage. Consistent control was achieved at a Zadoks growth stage 61 (rye anthesis). A thermal-based phenological model separating the effects of heat units accumulated in the fall (Fall(GDD)) from those accumulated in the spring (Spring(GDD)) best predicted the phenological development of cereal rye. Predicting when cereal rye can be successfully controlled using a roller/crimper along with the use of the thermal-based phenological model should aid growers in decision-making regarding cereal rye planting and termination dates.

TI gamma-Carboxylation of osteocalcin and insulin resistance in older men
and women

LA English
DT Article
ID VITAMIN-K SUPPLEMENTATION; HOMEOSTASIS MODEL ASSESSMENT; BONE-MINERAL
DENSITY; PLASMA-GLUCOSE; BETA-CELL; ADIPONECTIN; METABOLISM
AB Background: The skeletal protein osteocalcin is gamma-carboxylated by vitamin K. High serum uncarboxylated osteocalcin reflects low vitamin K status. In vitro and animal studies indicate that high uncarboxylated osteocalcin is associated with reduced insulin resistance. However, associations between osteocalcin and measures of insulin resistance in humans are less clear.
Objective: Our aim was to examine cross-sectional and longitudinal associations between circulating forms of osteocalcin (total, uncarboxylated, and carboxylated) and insulin resistance in older men and women.
Design: Cross-sectional associations between serum measures of total osteocalcin, carboxylated osteocalcin, and uncarboxylated osteocalcin and insulin resistance were examined in 348 nondiabetic men and women (mean age: 68 y; 58% female) by using the homeostasis model assessment of insulin resistance (HOMA-IR). Associations between each form of osteocalcin at baseline and 3-y change in HOMA-IR were examined in 162 adults (mean age: 69 y; 63% female) who did not receive vitamin K supplementation.
Results: Lower circulating uncarboxylated osteocalcin was not associated with higher HOMA-IR at baseline or at 3-y follow-up. Those in the lowest tertiles of total osteocalcin and carboxylated osteocalcin at baseline had higher baseline HOMA-IR (P = 0.006 and P = 0.02, respectively). The concentration of carboxylated osteocalcin at baseline was inversely associated with a 3-y change in HOMA-IR (P = 0.002).
Conclusions: In older adults, circulating uncarboxylated osteocalcin was not associated with insulin resistance. In contrast, elevated carboxylated osteocalcin and total osteocalcin were associated with lower insulin resistance, which supports a potential link between skeletal physiology and insulin resistance in humans. The role of vitamin K status in this association remains unclear and merits further investigation. This trial is registered at clinicaltrials.gov as NCT00183001. Am J Clin Nutr 2009; 90: 1230-5.

REPLACEMENT; PREMENOPAUSAL WOMEN
AB Background: Isoflavones are naturally occurring plant estrogens that are abundant in soy. Although purported to protect against bone loss, the efficacy of soy isoflavone supplementation in the prevention of osteoporosis in postmenopausal women remains controversial.
Objective: Our aim was to test the effect of soy isoflavone supplementation on bone health.
Design: A multicenter, randomized, double-blind, placebo-controlled 24-mo trial was conducted to assess the effects of daily supplementation with 80 or 120 mg of soy hypocotyl aglycone isoflavones plus calcium and vitamin D on bone changes in 403 postmenopausal women. Study subjects were tested annually and changes in whole-body and regional bone mineral density (BMD), bone mineral content (BMC), and T scores were assessed. Changes in serum biochemical markers of bone metabolism were also assessed.
Results: After study site, soy intake, and pretreatment values were controlled for, subjects receiving a daily supplement with 120 mg soy isoflavones had a statistically significant smaller reduction in whole-body BMD than did the placebo group both at 1 y (P < 0.03) and at 2 y (P < 0.05) of treatment. Smaller decreases in whole-body BMD T score were observed among this group of women at 1 y ( P, 0.03) but not at 2 y of treatment. When compared with the placebo, soy isoflavone supplementation had no effect on changes in regional BMD, BMC, T scores, or biochemical markers of bone metabolism.
Conclusion: Daily supplementation with 120 mg soy hypocotyl isoflavones reduces whole-body bone loss but does not slow bone loss at common fracture sites in healthy postmenopausal women. This trial was registered at clinicaltrials. gov as NCT00665860. Am J Clin Nutr 2009; 90: 1433-9.

First published August 5, 2009; doi:10.1152/ajpcell.00042.2009.Phosphorylated Akt (p-Akt), a phosphoinositide-3-OH-kinase-activated protein kinase, is highly expressed in prostate tumors. p-Akt can indirectly hinder p53-dependent growth suppression and apoptosis by phosphorylating Mdm2. Alternatively, p-Akt can directly phosphorylate p21 and restrict it to the cytoplasm for degradation. Because the prostate is the highest zinc-accumulating tissue before the onset of cancer, the effects of physiological levels of zinc on Akt-Mdm2-p53 and Akt-p21 signaling axes in human normal prostate epithelial cells (PrEC) and malignant prostate LNCaP cells were examined in the present study. Cells were cultured for 6 days in low-zinc growth medium supplemented with 0 [zinc-deficient (ZD)], 4 [zinc-normal (ZN)], 16 [zinc-adequate (ZA)], or 32 [zinc-supplemented (ZS)] mu M zinc. Zinc status of both cell types was altered in a dose-dependent manner, with LNCaP cells reaching a plateau at >16 mu M zinc. For both cell types, p-Akt was higher in the ZD than in the ZN cells and was normalized to that of the ZN cells by treatment with a PI3K inhibitor, LY-294002. PTEN, an endogenous phosphatase targeting Akt dephosphorylation, was hyperphosphorylated (p-PTEN, inactive form) in ZD PrEC. Nuclear p-Mdm2 was raised, whereas nuclear p53 was depressed, by zinc deficiency in PrEC. Nuclear p21 and p53 were lowered by zinc deficiency in LNCaP cells. Higher percentages of ZD, ZA, and ZS than ZN LNCaP cells were found at the G(0)/G(1) phase of the cell cycle, with proportionally lower precentages at the S and G(2)/M phases. Hence, the increased p-PTEN in ZD PrEC would result in hyperphosphorylation of p-Akt and p-Mdm2, as well as reduction of nuclear p53 accumulation. For ZD LNCaP cells, Akt hyperphosphorylation was probably mediated through p21 phosphorylation and degradation, thus restricting p21 nuclear entry to induce cell cycle arrest. Thus zinc deficiency differentially modulated the Akt-Mdm2-p53 signaling axis in normal prostate cells vs. the Akt-p21 signaling axis in malignant prostate cells.

Am J Physiol Endocrinol Metab 297: E1046-E1055, 2009. First published September 1, 2009; doi: 10.1152/ajpendo.00396.2009.-To determine the rates of methionine splanchnic uptake and utilization in critically ill pediatric patients we used two kinetic models: the plasma methionine enrichment and the "intracellular" homocysteine enrichment. Twenty four patients, eight infants, eight children, and eight adolescents, were studied. They received simultaneous, primed, constant, intravenous infusions of L-[(2)H(3)] methylmethionine and enteral L-[1-(13)C] methionine. The ratio of [(13)C] homocysteine to [(13)C] methionine enrichment was 1.0 +/- 0.15, 0.80 +/- 0.20, and 0.66 +/- 0.10, respectively, for the infants, children, and adolescents, and it was different between the infants and adolescents (P < 0.01). Methionine splanchnic uptake was 63, 45, and 36%, respectively, in the infants, children, and adolescents, and it was higher (P < 0.01) in the infants compared with the adolescents. The infants utilized 73% of methionine flux for nonoxidative disposal, while 27% was used for transulfuration (P < 0.001). Conversely, in the adolescents, 40% was utilized for nonoxidative disposal, while 60% was used for transulfuration. There is ontogeny on the rates of methionine splanchnic uptake and on the fate of methionine utilization in critically ill children, with greater methionine utilization for synthesis of proteins and methionine-derived compounds (P < 0.01) and decreased transulfuration rates in the infants (P < 0.01), while the opposite was observed in the adolescents. The plasma model underestimated methionine kinetics in children and adolescents but not in the infants, suggesting lesser dilution and greater compartmentation of methionine metabolism in the infant population. All patients were in negative methionine balance, indicating that the current enteral nutritional support is inadequate in these patients.

AB Cleveland BM, Weber GM, Blemings KP, Silverstein JT. Insulin-like growth factor-I and genetic effects on indexes of protein degradation in response to feed deprivation in rainbow trout (Oncorhynchus mykiss). Am J Physiol Regul Integr Comp Physiol 297: R1332-R1342, 2009. First published September 2, 2009; doi: 10.1152/ajpregu.00272.2009.-This study determined the effect of genetic variation, feed deprivation, and insulin-like growth factor-I (IGF-I) on weight loss, plasma IGF-I and growth hormone, and indexes of protein degradation in eight full-sibling families of rainbow trout. After 2 wk of feed deprivation, fish treated with IGF-I lost 16% less (P < 0.05) wet weight than untreated fish. Feed deprivation increased growth hormone (P < 0.05) and decreased IGF-I (P < 0.05), but hormone levels were not altered by IGF-I. Plasma 3-methylhistidine concentrations were not affected by IGF-I but were decreased after 2 wk (P < 0.05) and increased after 4 wk (P < 0.05) of feed deprivation. In white muscle, transcript abundance of genes in the ubiquitin-proteasome, lysosomal, and calpain-and caspase-dependent pathways were affected by feed deprivation (P < 0.05). IGF-I prevented the feed deprivation-induced upregulation of MAFbx (F-box) and cathepsin transcripts and reduced abundance of proteasomal mRNAs (P < 0.05), suggesting that reduction of protein degradation via these pathways may be partially responsible for the IGF-I-induced reduction of weight loss. Family variations in gene expression, IGF-I concentrations, and weight loss during fasting suggest genetic variation in the fasting response, with considerable impact on regulation of proteolytic pathways. These data indicate that nutrient availability, IGF-I, and genetic variation affect weight loss, in part through alterations of proteolytic pathways in rainbow trout, and that regulation of genes within these pathways is coordinated in a way that supports a similar physiological response.

AB Phytophthora infestans, the causal agent of late blight is the most devastating pathogen of cultivated potato worldwide. Utilizing map based cloning; a genomic region containing a cluster of six nucleotide binding site-leucine-rich repeat resistance gene analogs was isolated from the wild potato species Solanum bulbocastanum. Four genes were pseudogenes, with coding sequences interrupted by either frame shift mutations or premature stop codons. However, neither of the two uninterrupted genes conferred resistance to P. infestans when introduced into susceptible potatoes. Specific primers for one of the pseudogenes were used to amplify an uninterrupted cDNA from P. infestans-infected S. bulbocastanum leaves. A corresponding gDNA was amplified from a late blight-resistant bulbocastanum-tuberosum introgression line (Rpi-bt1). The Rpi-bt1 gene under transcriptional control of the constitutive potato Ubi3 promoter was found to confer resistance to P. infestans in several transgenic potato lines in a whole plant greenhouse assay.

AB Late blight, caused by the oomycete pathogen, Phytophthora infestans, is a devastating disease of potatoes and tomatoes. A key long-term management strategy for combating this disease is to develop potato cultivars with broad-spectrum and durable resistance through identification and integration of major resistance genes. In support of previous results, we have determined that some accessions of the wild potato species Solanum verrucosum contain strong foliar resistance to P. infestans while others are susceptible. In addition, whole-and wounded-tuber inoculations revealed that most accessions lacked resistance to tuber infection. However, one accession (PI 570643) contained little foliar resistance but expressed tuber resistance, suggesting that expression of these two phenotypes in this species is not correlated.

AB Zebra chip (ZC) is an emerging and damaging disease of potato (Solanum tuberosum L.) that has been documented in potato fields throughout the southwestern United States, Mexico, Central America, and most recently New Zealand. The bacterium "Candidatus Liberibacter" has been putatively identified as the causal agent of this disease and the potato psyllid, Bactericera cockerelli (Sulc), as the insect vector. Tuber symptoms of ZC-infected plants include collapsed stolons, enlarged lenticels, vascular tissue browning, medullary ray discoloration, and necrotic flecking. ZC tuber symptoms are similar to those of potato diseases which exhibit perturbations in tuber mineral composition resulting in internal necrotic disorders. To determine the effect of ZC disease on the mineral content of potato tubers, concentrations of P, K, S, Ca, Mg, Na, Fe, Al, Mn, Cu, Zn, and B were analyzed in 'Atlantic' potatoes from ZC-infected and free plants, for both tuber flesh and peel tissues. The potatoes were grown at Weslaco, TX and Wapato, WA, two different and distant geographical locations under controlled cage conditions. Results showed that flesh tissue from ZC-infected tubers had significantly higher concentrations of P, K, and Ca at both locations, whereas, ZC-infected tuber flesh from Weslaco had higher concentrations of Mg, Cu, Zn, and B, while concentrations of Fe and Al were higher in ZC-infected tuber flesh from Wapato. Peel tissue from ZC-infected tubers were found to have a significantly higher level of Zn at both locations, whereas the levels of P and Na were found to significantly higher in peel tissue from Wapato and Weslaco, respectively. Finally, Mg was found to be significantly higher in ZC-free tubers from both locations and levels of Cu and B were significantly higher in ZC-free peel tissue from Wapato.

AB Early blight, caused by Alternaria solani, is an important foliar disease in potatoes around the world. Heritable early blight resistance was previously identified in a population of Solanum phureja-S. stenotomum (phu-stn). Seventy-two clones, consisting of the most early-blight resistant clone from each of the 72 phu-stn families in this population, were randomly intermated and four horticulturally good clones from each family were selected to constitute the second cycle population. The objective of this study was to determine if this recurrent selection strategy would improve levels of early blight resistance in the second cycle population. Clones from the second cycle population were evaluated in a replicated field trial for two years in Pennsylania, USA. Area under the disease progress curve was calculated from estimates of the percentage of necrotic lesions and defoliation. Broad-sense heritability for resistance was 0.75, with a 95% confidence interval of 0.69-0.81. Narrow-sense heritability was 0.63 +/- 0.29. However, the second cycle population was more susceptible and later in maturity than the first cycle population. Because of the negative association between earliness and resistance to early blight, it is likely that selecting horticulturally good clones to constitute the second cycle population favored susceptibility. Alternate breeding strategies to improve early blight resistance will have to be devised.

AB In 2002, Columbia Basin potato growers in Washington and Oregon began to experience serious outbreaks of potato purple top disease that have caused significant yield losses and reductions in tuber quality. It was determined that the beet leafhopper-transmitted virescence agent (BLTVA) phytoplasma is the causal agent of the disease in the Columbia Basin and that this pathogen is transmitted by the beet leafhopper. Little is known about the impact of purple top disease on potato in the Pacific Northwest. Trials were conducted in 2006, 2007, and 2008 to assess susceptibility of important potato cultivars grown in the Columbia Basin to purple top under field conditions. Eight potato cultivars were planted in small field plots and exposed to naturally occurring BLTVA-infected beet leaf-hoppers. Disease incidence was recorded at the end of the growing season. Purple top foliar symptoms were observed in all the tested cultivars, and plant samples collected and tested by PCR confirmed the presence of BLTVA. Results also indicated significant differences in susceptibility of the cultivars to purple top. Disease incidence in leafhopper-exposed plots ranged from 1.5 to 49.3% among cultivars. Russet Norkotah, Ranger Russet, and Umatilla Russet were relatively high in susceptibility to purple top, with average disease incidence of 33.5, 23.3, and 19.4%, respectively. Russet Burbank and FL1967 showed some resistance to purple top as they had the lowest plant disease incidence of 2.3 and 4.4%, respectively. Alturas, Shepody, and FL 1879 were moderately susceptible to purple top, with average disease incidence of 12.8, 8.0, and 9.3%, respectively. Information from this study will help potato growers reduce damage caused by potato purple top through selection of cultivars that are resistant to or tolerant of the disease and by protecting susceptible varieties against the beet leafhopper.

AB Verticillium wilt (VW), caused mainly by the soil-borne fungus V. dahliae, is a persistent and serious problem in potato production. Host-plant resistance offers an attractive control strategy, but most major cultivars are susceptible to VW. Resistance to VW was evaluated in 14 advanced clones from U. S. potato breeding programs and 11 cultivars. The two objectives of this study were to 1) determine the extent to which VW resistance exists in advanced selections in U. S. potato breeding programs and 2) test a selection strategy based on multiple measures of resistance. The three measures of resistance used in this study were symptom expression in the field, colonization of stem sap, and numbers of propagules in senescent stems. Resistant clones had low scores, but susceptible clones were highly variable for all three measures. An effective selection strategy utilizing all three measures of assessment can be used to separate true resistance from tolerance as follows: first, identify clones with low symptom expression, then measure sap colonization, and finish by establishing propagule levels in senescent stems. Based on this approach, breeders will be able to identify VW resistant, and not just VW tolerant, germplasm for future breeding efforts.

AB The potato psyllid, Bactericera cockerelli Sulc, has recently been identified as a vector of Candidatus Liberibacter solanacearum, the putative causal agent of zebra chip potato disease. Zebra chip is causing millions of dollars in losses to the potato industry in the United States, Mexico, Central America, and New Zealand. Currently, the most effective strategy to manage this potato disease is to target the potato psyllid with insecticides. Effective management of this insect pest requires knowledge of its biology, ecology, geographic distribution, and population dynamics. Although it is well documented that the potato psyllid is common throughout the western United States, several reports have indicated that this insect pest does not occur in Washington and Oregon. However, this insect has recently been observed and collected in this region. Studies were conducted from 2005 to 2008 to document and determine the seasonal occurrence of the potato psyllid in this important potato growing region of the United States. The potato psyllid was monitored in untreated experimental potato plots at Moxee and Prosser in south central Washington. Contrary to previous reports, the potato psyllid was found to occur in Washington and appears to migrate into the region late in the growing season. Upon arrival in south central Washington in late July, this insect readily reproduces in potatoes and appears to have at least one generation a year. The origin of potato psyllids migrating to Washington has not yet been determined. Information from this study will help potato growers in Washington manage the potato psyllid to better prevent potential zebra chip outbreaks.

AB Environmental stress during the growing season can reduce the quality of stored Solanum tuberosum (potato) tubers. Changes in greenhouse grown Russet Burbank tuber water potential and tuber composition following periods of moderate drought, heat, or drought and heat stress were characterized. Decreased leaf and tuber water potentials were observed at the end of stress treatments. Decreased tuber water potential caused dramatic declines in tuber pressure potential. Tuber sucrose content increased with the severity of stress. Changes in tuber glucose and malic acid contents were also observed. Stress during early tuber bulking had a larger effect on tuber sugars at the end of the stress period than stress during late bulking. Stem-end glucose concentration of tubers at harvest after vine senescence was greater in tubers from plants stressed at early tuber bulking compared to late bulking.

AB For sensitive and specific toxin detection, mycotoxin immunoassays depend upon antibodies with high affinity and selectivity. While intact immunoglobulins remain the primary toxin-binding elements used in rapid assays, a number of alternatives have begun appearing in the literature. The alternatives can be broadly classified into those that are obtained by chemical synthesis and those that are obtained by altering biologically derived materials. Examples range from synthetically prepared polymers to recombinant fragments of antibodies, with a wide variety of synthetic and natural materials in-between. To date, obtaining the combination of selectivity and affinity needed for use in sensors has been more readily accomplished with biologically derived materials than with synthetic materials. Despite this, synthetic materials still offer certain potential advantages, such as high binding capacity and the ability to bind in environments that are too harsh for intact antibodies. This review focuses upon recent advances in the development of mycotoxin-binding materials and their potential for application in mycotoxin assays.

TI Sampling and analytical variability associated with the determination of

AB Ginger has been used as a food, dietary supplement, and condiment for centuries. Mycotoxins such as the aflatoxins (AF) and ochratoxin A (OTA) have been reported in ginger roots in several studies. It is important to design effective sampling methods that will accurately and precisely predict the true mycotoxin level in a bulk lot. The objective of this study was to measure the sampling and analytical variability associated with the test procedure used to measure AF and OTA in a bulk lot of powdered ginger using a 5-g laboratory sample and HPLC analytical methods. Twelve 5-g laboratory samples were taken from each of two lots. Duplicate aliquots were removed from each 5-g laboratory sample/solvent blend, and each aliquot was simultaneously analyzed for AF and OTA by HPLC analytical methods. Using a balanced nested design, the total variance associated with the above AF and OTA test procedures was partitioned into sampling and analytical variance components for each lot. Averaged across both lots, the sampling and analytical variances accounted for 87% and 13% of the total variance, respectively, for AF and 97% and 3%, respectively, for OTA. The sampling and analytical coefficients of variation were 9.5% and 3.6%, respectively, for AF, and 16.6% and 2.9%, respectively, for OTA when using a single 5-g laboratory sample and HPLC analytical methods. Equations are derived to show the effect of increasing laboratory sample size and/or number of aliquots on reducing the variability of the test procedures used to estimate OTA and AF in powdered ginger.

AB Cholecystokinin (CCK) and the different molecular forms of CCK are well established as biomarkers for satiety but accurate analysis has been limited by the multiple naturally occurring forms and extensive similarities to gastrin. Changes in levels of one form, CCK-8, a naturally occurring eight amino acid peptide of CCK, have been correlated with satiety responses. Endogenous CCK-8 has not been well characterized in Syrian Golden hamsters, an important model in the study of fat uptake and digestion. We have cloned and sequenced hamster CCK and identified and characterized endogenous CCK-8 from hamster plasma. Hamster CCK-8 is composed of eight amino acid residues which are highly conserved among other species. Following accurate identification and characterization of hamster CCK-8, we have developed a highly specific and sensitive immunoprecipitation based LC-MS/MS assay for its quantification. The present assay enables determination of active CCK-8 over a concentration range from 0.05 to 2.5 ng/mL in hamster plasma samples. This range covers both the basal and postprandial levels of CCK-8. Method performance validation samples were examined at three concentrations replicated over the course of 4 days. The assay accuracy (percent relative error, % RE) average was 11.3% with a precision (percent coefficient of variation, % CV) of 15.5% over all samples in this 4 day period. Additionally, the method was used to determine increases of endogenous plasma CCK-8 in hamsters challenged with a high-fat meal.

AB Collections of parasitoids attacking the soybean aphid, Aphis glycine Matsumura (Hemiptera: Aphididae), in South Korea yielded specimens that were originally identified as Binodoxys communis (Gahan) (Hymenoptera: Braconidae). We report here on laboratory studies indicating that this population is actually a previously unknown species of Binodoxys. Four classes of comparisons were made between the Korean population and a Chinese population that also had been identified as B. communis. The comparisons included 1) mating trials coupled with behavioral observations and spermathecal examinations, 2) assessment of nucleotide divergence at two mitochondrial and two nuclear gene loci, 3) patterns of host use, and 4) reassessment of morphological characters. These studies revealed premating reproductive isolation of the two populations and minor nucleotide differences in mitochondrial cytochrome oxidase I sequences and nuclear internal transcriber spacer 1 sequences, providing strong indications that they are different species. Subtle morphological differences also were discovered that confirmed that the Chinese population corresponds to B. communis, whereas the Korean population does not:. We propose the name Binodoxys koreanus Stary, sp. n. for the Korean Population. The two species exhibited similar host ranges in the laboratory, the most notable exception being that B. koreanus, sp. n. is better able to develop in a Population of Aphis craccivora Koch that harbors the bacterial endosymbiont Hamiltonella defensa Moran, which seems to strongly interfere with the development of B. communis. We discuss the implications of our results for biological control introductions against the soybean aphid in North America.

AB Wing venation, two-dimensional and with easily recognized reference points at vein junctions, presents an opportunity for the development of automated insect identification. Using a suite of continuous characters, I investigated the use of wing morphometry for computerized insect identification of cryptic species of the aphid genus Mindarus. A priori groups were determined using cytochrome oxidase 1 DNA barcodes. Discriminant function analysis of 24 wing measurements consistently grouped individuals Of unknown taxonomic affinity with the correct a priori groups. The results suggest that diagnostic signal is present in wing morphometry, but the signal is considerably stronger with the addition of morphometry from other aphid appendages, namely, 10 leg and antenna] segments. Almost all Mindarus collected in eastern North America have been determined as the balsam twig aphid, Mindarus abietinus Koch (Hemiptera: Aphididae), but molecular diagnostics reveals that the Palearctic species is not present in the Western Hemisphere. Schizoneura pinicola Thomas has been considered a North American synonym of M. abietinus. Morphometric discriminant function analysis suggests that the Abies-feeding eastern North American population is M. pinicolus. The species is here reinstated with a new combination and redescribed.

AB Dendroctonus pseudotsugae Hopkins infests Douglas-fir, Pseudotsuga menziesii (Mirb.) Franco, throughout the distribution of that tree species from British Columbia to northern Mexico. The Subspecies Dendroctonus pseudotsugae barragani Furniss was described from the mountains of Chihuahua, Sierra Madre Occidental, Mexico, whereas the nominal subspecies, Dendroctonus pseudotsugae pseudotsugae Hopkins, occurs north of Mexico. The description of D. p. barragani was based on the only known Mexican population at that time. More recently, new populations of this beetle have been discovered at 13 additional localities in Chihuahua, Durango, Coahuila, and Nuevo Leon, Mexico. To test whether these additional populations support the existence of two subspecies, we performed a taxonomic reassessment combining molecular markers (cytochrome oxidase 1), morphological characters used in the original description, and newly described morphological characters. Phylogenetic analysis of 89 haplotypes confirms that the Mexican populations are distinct from the sampled populations in the United States and Canada. Morphological analysis indicates that intraspecific variation is greater than previously considered within Mexican populations. However, at least seven characters on the head, pronotum, and elytra (including three previously undescribed characters of frons sculpture) consistently discriminate among Canada-U.S. and Mexico populations. The extension of the known distribution of this beetle in Mexico and verification of its subspecific status will aid in the management and conservation of Pseudotsuga in Mexico.

AB Rhagoletis pomonella (Walsh) (Diptera: Tephritidae) is a quarantine pest of apple (Malus sp.) in Washington state that is almost identical morphologically to Rhagoletis zephyria Snow, a nonpest of apple. Historically, the longer ovipositor in R.pomonella has been used to separate it front R. zephyria, despite overlap in ovipositor lengths. Here, the objectives were to determine whether use of multiple body measurements and wing shape can improve discrimination of the species. Ovipositor lengths allowed 94.6% correct identification of female R. pomonella but only 7.0% correct identification of R. zephyria. We found that multiple body measurements and wing shape can better separate these species. Canonical variates analysis (CVA) of nine body measurements in female flies largely separated the species. In contrast, CVA of nine body measurements poorly separated the males of these species. Discriminant analysis using nine body measurements classified female R. pomonella and R. zephyria with 95.4 and 100% accuracy, respectively. Geometric morphometries and CVA separate(] wing shapes between species in both sexes. Bookstein shape coordinates indicated that the wing of R. pomonella is more tapered at the tip than that of R. zephyria. Use of wing shape in an assignments test identified female R. pomonella with 98.5% and female R. zephyria with 99.0% accuracy, and it correctly identified 100% of flies whose identities were questionable based on ovipositor lengths. Results indicate that use of multiple body measurements or wing shape is an improvement over the use of ovipositor length alone for identifying female R. pomonella and R. zephyria in Washington state.

AB The objectives of these studies were to determine cell yield and fermentation responses of a Salmonella enterica serovar Typhimurium poultry isolate using various dilution rates in steady state continuous culture incubations. S. enterica Typhimurium cells were propagated in continuous cultures with a total volume of 0.50 l of Luria Bertani medium containing 0.1% glucose. Dilution rates from 0.0125 to 1.44/h were used. Cell protein concentration generally increased linearly with increased dilution rate up to a rate of 0.54/h and declined at the higher dilution rates. Glucose consumption gave a similar pattern to cell protein concentration by declining at the three highest dilution rates. Short chain fatty acid production was inconsistently influenced by dilution rate. Acetate, the most predominant fatty acid produced, declined at the higher dilution rates, as did propionate. Ammonia production remained stable at the lowest dilution rates, but increased significantly at a dilution rates above 0.27/h.

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

AB The diversity of uncultured Frankia populations in root nodules of Alnus oblongifolia trees geographically isolated on mountaintops of central Arizona was analyzed by comparative sequence analyses of nifH gene fragments. Sequences were retrieved from Frankia populations in nodules of four trees from each of three mountaintops (n = 162) and their levels of diversity compared using spatial genetic clustering methods and single-nucleotide or 1, 3, or 5% sequence divergence thresholds. With the single-nucleotide threshold level, 45 different sequences with significant differences between the mountaintops were retrieved, with the southern site partitioning in a separate population from the two other sites. Some of these sequences were identical in nodules from different mountaintops and to those of strains isolated from around the world. A high level of diversity that resulted in the assignment of 14 clusters of sequences was also found on the 1% divergence level. Single-nucleotide and 1% divergence levels thus demonstrate microdiversity of frankiae in root nodules of A. oblongifolia trees and suggest a partitioning of diversity by site. At the 3 and 5% divergence levels, however, diversity was reduced to three clusters or one cluster, respectively, with no differentiation by mountaintop. Only at the 5% threshold level do all Frankia strains previously assigned to one genomic group cluster together.

AB Four saline crops [athel (Tamarix aphylla L), eucalyptus (Eucalyptus camaldulensis), Jose Tall Wheatgrass (Agropyron elongatum), and Creeping Wild Ryegrass (Leymus triticoides)] that are used in farms for salt uptake from soil and drainage irrigation water have the potential for fuel ethanol production because they don't take a large number of arable lands. Dilute sulfuric acid pretreatment and enzymatic hydrolysis were conducted to select the optimum pretreatment conditions and the best saline crop for further enzymatic hydrolysis research. The optimum dilute acid pretreatment conditions included T = 165 degrees C, t = 8 min, and sulfuric acid concentration = 1.4% (w/w). Creeping Wild Ryegrass was decided to be the best saline crop. Solid loading, cellulase and beta-glucosidase concentrations had significant effects on the enzymatic hydrolysis of dilute acid pretreated Creeping Wild Ryegrass. Glucose concentration increased by 36 mg/mL and enzymatic digestibility decreased by 20% when the solid loading increased from 4 to 12%. With 8% solid loading, enzymatic digestibility increased by over 30% with the increase of cellulase concentration from 5 to 15 FPU/g-cellulose. Under given cellulase concentration of 15 FPU/g-cellulose, 60% increase of enzymatic digestibility of pretreated Creeping Wild Ryegrass was obtained with the increase of beta-glucosidase concentration up to 15 CBU/g-cellulose. With a high solid loading of 10%, fed-batch operation generated 12% and 18% higher enzymatic digestibility and glucose concentration, respectively, than batch process. (C) 2009 Elsevier Ltd.

AB Application of crop production and protection materials is a crucial component in the high productivity of American agriculture. Agricultural chemical application is frequently needed at specific times and locations for accurate site-specific management of crop pests. Piloted agricultural aircraft are typically used to treat large, unobstructed, continuous acreage crops and are not as efficient when, working over small or obstructed plots. An Unmanned Aerial Vehicle (UAV), which can be remotely controlled or fly autonomously based on pre-programmed flight plans, may be used to make timely and efficient applications over these small area plots. This research developed a low volume spray system for use on a fully autonomous UAV to apply crop protection products on specified crop areas. This article discusses the development of the spray system and its integration with the flight control system of a fully autonomous, unmanned vertical take-off and landing helicopter Sprayer actuation can be triggered by preset positional coordinates as monitored by the equipped Global Positioning System (GPS). The developed spray system has the potential to provide accurate, site-specific crop management when coupled with UAV systems. It also has great potential for vector control in the areas that are not easily accessible by personnel or equipment.

ID CONSERVATION TILLAGE; SOIL; COTTON
AB In a weed-free field with ideal weather conditions, a cash crop can be planted 3 weeks after rolling a mature cereal rye winter cover crop without using herbicides. However, cloudy and wet weather can delay the rolling and/or desiccation of rye, thereby delaying cash crop planting which can negatively impact yield. One effective way to reduce the time between rolling and planting is to spray herbicide while rolling. However, a continuous spray may not be required if a roller/crimper is used due to the additive effect of the roller. Two different methods of applying glyphosate (Roundup (TM)) to rolled rye were compared. First, a felt strip saturated with herbicide was attached to the roller's crimping bar to provide glyphosate application with every crimp. The second method consisted of a boom (five nozzles controlled by solenoid valves) mounted on the roller applying a spray continuously, and intermittent spray every second crimp, or every fourth crimp. The average results over three growing seasons showed that 7 days after rolling, rye termination rates for all rolled/glyphosate treatments surpassed 90% (91% for glyphosate saturated felt strip and 98% for continuous spray), exceeding the termination rates for rye recommended to planting cash crops into rye residue cover. For the roller/crimper alone and the non-treated check (standing rye), termination rates were 82% and 54%, respectively. Since spraying glyphosate every fourth crimp provided a 93% termination rate one week after rolling, this method may facilitate planting the cash crop in a timely fashion while reducing input costs. Economic savings of $12.63 to $36.87 ha(1) may be attained by incorporating herbicide applications with rolling activities. One and two weeks after the rolling treatment, volumetric soil moisture content for all rolled rye/chemical treatments were significantly higher than the non-treated check.

AB A 2-yr study was conducted during 2006-2007 and 2007-2008 to evaluate the effects of outdoor weathering on the nutritive value, ruminal disappearance kinetics of dry matter (DM), and recoveries of DM from 1.4- x 1.2-m large-round bales. The study consisted of (n = 90) bales that were allocated within a 2 x 5 factorial arrangement of hay types [orchardgrass (Dactyl is glomerata L.) or alfalfa (Medicago sativa L.)] and storage treatments. Bales were wrapped with either sisal twine or net, and they were positioned outdoors either elevated on wooden pallets or directly on the ground. For both hay types, positive controls were wrapped with net and stored indoors. Generally, the main effects of hay type and storage treatment did not interact, but both main effects interacted with year During 2006-2007, wrapping with net did not improve recovery of DM compared to bales wrapped with twine (93.7% vs. 93.4%; P = 0.781), but recovery was improved by elevating bales on wooden pallets (95.0% vs. 92.1%; P < 0.00.1). However, control hays surpassed by 4.6 percentage units the overall recovery mean for all bales wintered outdoors (98.1% vs. 93.5%; P < 0.001). Precipitation was above normal during 2007-2008; this resulted in a 7.3-percentage-unit recovery advantage for indoor storage compared to all bales stored outdoors. Unlike the previous year, bales wrapped with twine and placed directly oil the ground were especially vulnerable to weathering, recovering only 85.2% of initial DM, while recoveries for other treatments stored outdoors ranged from 89.6% to 91.1%. During tire relatively dry conditions observed during 2006-2007, the energy density (total digestible nutrients; TDN) of the 0.15-m surface layer for all bales wintered outdoors was depressed, but by only 1.4 percentage units (60.8% vs. 59.4%; P = 0.017) relative to indoor controls. With much greater precipitation during 2007-2008, this differential increased only marginally (57.3% vs. 54.1%; P < 0.00.1). Generally, kinetic estimates obtained from in situ evaluations of ruminal disappearance of DM were consistent with responses observed for TDN. In summary, recoveries of DM front large-round bales always were greatest with indoor storage. The results of these studies suggest that elevating bales off of the soil surface and wrapping with net offer the highest probability of maximizing recovery of DM following outdoor winter storage in northern climates.

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

AB A low-cost system was deployed above a swine waste lagoon to obtain estimates of Bowen ratios and characterize lagoon temperatures. The system consisted of humidity and temperature sensors and anemometers deployed above the lagoon, water temperature sensors, and a meteorological station located by the lagoon. To evaluate the system, data was analyzed front the 25th through 28th June 2007. Bowen ratios showed diurnal behavior near the lagoon surface characterized by negative values during day and positive ones at night. Latent (evaporation) and sensible heat fluxes were towards the atmosphere and the lagoon, respectively for most of the day. A diurnal cycle in atmospheric and lagoon temperatures was also observed. Furthermore, wind speeds above the lagoon were highest in the afternoon. These variations were linked to lagoon temperature stratifications which became more pronounced as wind speeds increased. Temperature stratification at the lagoon indicated increased heat exchange at the lagoon's interface with the atmosphere. During the night, the stratification disappeared and temperatures in the water column were almost identical down to about 60 cm. This behavior is similar to that observed in other shallow water bodies that are fetch-limited. Lagoon hearing was driven by the diurnal cycle of solar radiation and net radiation. This suggests that Bowen ratios had an inverse relationship with lagoon heating and its thermal stratification. This also indicates that there was an increase in latent heat flux and evaporation during the daytime. These results are important for characterizing the thermal behavior of the lagoon leading to a better representation of processes responsible for emissions.

AB Although lye peeling is the widely industrialized method for producing high quality peeled fruit and vegetable products, the peeling method has resulted in negative impacts by significantly exerting both environmental and economic pressure on the tomato processing industry due to its associated salinity issues and wastewater disposal problems. The objective of this research was to develop alternative peeling methods with reduced or no caustic usage to produce high quality peeled tomatoes. The feasibility of using infrared radiation (IR) peeling and lye-IR peeling as alternative technologies was evaluated against control treatment which used regular lye peeling alone. Peeling performance and peeled tomato quality of three tomato cultivars were determined. The metrics for peeling performance were peelability, peeling easiness, and peeling weight loss. The color and texture of peeled tomatoes were measured as quality indicators. The study showed that IR peeling resulted in a similar peeling easiness but yielded lower peeling loss and firmer peeled product for the same or slightly longer peeling time when compared to regular lye peeling method. Pretreatment with low concentration of lye solution prior to IR treatment did not show any advantages over IR peeling alone. Because IR dry-peeling produced high quality product without using water and salts, it is concluded that it has a good potential as an alternative peeling method to the regular lye peeling method.

AB The effects of natural enemy releases on conservation genetics within ecosystems are rarely considered. Diadegma semiclausum (Hellen) (Hymenoptera: Ichneumonidae) was introduced and continues to be released for biological control of diamondback moth in Japan. Diadegma semiclausum and indigenous Diadegma fenestrale (Holmgren) (Hymenoptera: Ichneumonidae) share geographic ranges and hosts, and produce offspring when mated under laboratory conditions. We used DNA to examine whether offspring from inter-specific one-way parental crosses (D. semiclausum female and D. fenestrale male) were. hybrid, as some Hymenoptera (e.g. Aphidius colemani Viereck (Hymenoptera: Braconidae)) exhibit thelytokous reproduction by gynogenesis. Molecular analyses revealed offspring mtDNA (COI) is maternally inherited, as expected, but rRNA (ITS-2) originates from both parents. Should similar hybridization occur in the field beyond the F1 generation, genetic mixing is a possible consequence that may influence biological control efficacy or pollute native population genetics.

AB Pseudomonas resinovorans, a known medium-chain-length (mcl-) poly(hydroxyalkanoate) (PHA) producer, was grown on 13-methyltetradecanoic acid (13-MTDA) and a mixture of isostearic acid (IA) isomers to produce methyl-branched mcl-PHA polymers. Shake-flask experiments revealed polymer productivities (the percent of the cell mass that is polymer) of 31 +/- 1% (n = 3) and 23 +/- 3% (n = 3) when grown in 13-MTDA and IA, respectively. Monomer content was determined by a combination of gas chromatography/mass spectrometry (GC/MS) of the acid hydrolyzed, silylated methyl esters, and nuclear magnetic resonance spectroscopy. Results showed that the mcl-PHA polymer derived from 13-MTDA was primarily composed of 3-hydroxy-7-methyloctanoic acid and 3-hydroxy-9-methyldecanoic acid (67 and 16 mol% by GC/MS, respectively). In contrast, the mcl-polymers synthesized from the IA isomeric mixture were more complex, containing both even and odd chain-length monomers as well as varying distributions of methyl-branched derivatives. The PHA distributions among the C8, C10, C12, and C14 carbon chain-length monomers included three isomers of C8, five isomers of C10, seven isomers of C12, and nine isomers of C14 each containing one linear-chain derivative and n-6 methyl-branched derivatives where n equals the total number of carbon atoms in each monomer unit (C8-C14).

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

TI An Ecological Risk Assessment of the Acute and Chronic Effects of the
Herbicide Clopyralid to Rainbow Trout (Oncorhynchus mykiss)
SO ARCHIVES OF ENVIRONMENTAL CONTAMINATION AND TOXICOLOGY
LA English
DT Article
ID RELATIVE SENSITIVITY; BULL TROUT; RANGELAND
AB Clopyralid (3,6-dichloro-2-pyridinecarboxylic acid) is a pyridine herbicide frequently used to control invasive, noxious weeds in the northwestern United States. Clopyralid exhibits low acute toxicity to fish, including the rainbow trout (Oncorhynchus mykiss) and the threatened bull trout (Salvelinus confluentus). However, there are no published chronic toxicity data for clopyralid and fish that can be used in ecological risk assessments. We conducted 30-day chronic toxicity studies with juvenile rainbow trout exposed to the acid form of clopyralid. The 30-day maximum acceptable toxicant concentration (MATC) for growth, calculated as the geometric mean of the no observable effect concentration (68 mg/L) and the lowest observable effect concentration (136 mg/L), was 96 mg/L. No mortality was measured at the highest chronic concentration tested (273 mg/L). The acute:chronic ratio, calculated by dividing the previously published 96-h acutely lethal concentration (96-h ALC(50); 700 mg/L) by the MATC was 7.3. Toxicity values were compared to a four-tiered exposure assessment profile assuming an application rate of 1.12 kg/ha. The Tier 1 exposure estimation, based on direct overspray of a 2-m deep pond, was 0.055 mg/L. The Tier 2 maximum exposure estimate, based on the Generic Exposure Estimate Concentration model (GEENEC), was 0.057 mg/L. The Tier 3 maximum exposure estimate, based on previously published results of the Groundwater Loading Effects of Agricultural Management Systems model (GLEAMS), was 0.073 mg/L. The Tier 4 exposure estimate, based on published edge-of-field monitoring data, was estimated at 0.008 mg/L. Comparison of toxicity data to estimated environmental concentrations of clopyralid indicates that the safety factor for rainbow trout exposed to clopyralid at labeled use rates exceeds 1000. Therefore, the herbicide presents little to no risk to rainbow trout or other salmonids such as the threatened bull trout.

AB Objective: Compared to vegetable oils in their unmodified state, partially-hydrogenated fat is associated with less favorable effects on cardiovascular disease (CVD) risk factors. Acceptable alternatives must be adjudicated. Our objective was to assess the effect of a recent commercial fat substitution, corn oil for partially-hydrogenated soybean oil.
Methods: Using a double-blind cross-over design, 30 postmenopausal women >= 50 years with LDLcholesterol concentrations >= 120 mg/dL were randomly assigned to each of two 35-day phases; all food and beverage was provided to maintain body weight. Corn or partially-hydrogenated soybean oil was incorporated throughout the diet and contributed two-thirds of fat. Primary outcomes included fasting and non-fasting lipid, lipoprotein, apolipoprotein, and fasting high sensitivity C-reactive protein (hsCRP) concentrations; secondary outcomes included fasting small dense LDL (sdLDL)-cholesterol, remnant lipoprotein cholesterol (RemLC), glycated albumin, adiponectin and immunoreactive insulin concentrations, and endogenous cholesteryl ester transfer protein ( CETP) and lecithin: cholesterol acyl transferase (LCAT) activities.
Results: Relative to the partially-hydrogenated soybean oil enriched diet, the corn oil enriched diet resulted in lower fasting total cholesterol (7%; P < 0.0001), LDL-cholesterol (10%; P < 0.0001), VLDL-cholesterol ( 7%; P = 0.052), apo B ( 9%; P < 0.0001), lipoprotein ( a) [Lp(a)] (5%; P = 0.024), sdLDL-cholesterol (17%; P = 0.001), and RemLC (20%; P = 0.007) concentrations, and no significant effect on the other outcomes. Changes in postprandial (4-h post-meal) lipid, lipoprotein and apolipoprotein concentrations were similar to the fasting state.
Conclusion: The replacement of partially-hydrogenated soybean oil with corn oil favorably affects a range of CVD risk factors and is an appropriate option to decrease cardiovascular disease risk factors in moderately hypercholesterolemic individuals.

AB Bats alter their echolocation in response to changes in ecological and behavioral conditions, but little is known about how they adjust call structure in response to changes in altitude. We examined altitudinal variation in the echolocation of Brazilian free-tailed bats, Tadarida brasiliensis, a species known to fly to altitudes of 3,000 m above the ground. From 50.2 h of recordings, we analyzed 113 high-quality echolocation call sequences recorded from 0 to 862 m above ground level. Bats flying near the ground used shorter, higher-frequency, broader-bandwidth calls compared to bats at higher altitudes, an effect likely due to the greater levels of echo-producing clutter (i.e., vegetation, buildings) found near the ground. When ground-level recordings are excluded, bats continue to shift towards the use of longer-duration, lower-frequency, narrower-bandwidth calls with increasing altitude. We propose that the observed high-altitude changes in call structure are a response to changing acoustic attenuation rates and/or decreasing insect densities at higher altitudes.

AB Urine deposition has been observed as an important scent-marking behaviour among wolverines (Gulo gulo, Mustelinae, Mustelidae). Solid phase microextraction (SPME) of headspace volatiles of the urine from free ranging wolverines were examined by gas chromatography-mass spectrometry (GC-MS). Urine samples were collected directly from the bladder of live-trapped animals or from frozen samples deposited in snow. Nineteen potential semiochemicals were identified in the headspace from 22 urine samples. The composition of these volatile compounds varied by type and amount with each sample, but a number of chemicals were regularly found in many samples. The most commonly found constituents were the ketones; 2-heptanone, 4-heptanone and 4-nonanone; and the terpenes: alpha-pinene, beta-pinene, limonene, linalool and geraniol. Mammalian urinary discharge of ingested alpha-pinene, beta-pinene, limonene and other hydrocarbon terpenes is. unusual, as these compounds are usually oxidized before excretion. The source of the hydrocarbon monoterpenes likely includes conifer needles, as they have been found in wolverine scat. (C) 2009 Elsevier Ltd. All rights reserved.

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

AB Kroll et al. [Kroll, A.J., Runge, J.P., MacCracken, J.G., 2009. Unreliable amphibian population metrics may obfuscate more than they reveal. Biological Conservation] criticized our recent advocacy for combining readily attainable metrics of population status to gain insight about relationships between terrestrial plethodontid salamanders and forest succession [Welsh, Jr., H.H., Pope, K.L., Wheeler, C.A., 2008. Using multiple metrics to assess the effects of forest succession on population status: a comparative study of two terrestrial salamanders in the US Pacific Northwest. Biological Conservation 141, 1149-1160]. They argue that each of our metrics has the potential to be biased or flawed and, therefore, any inferences so derived are likely to be uncertain and misleading. One of our main goals was to highlight the value of combining multiple quantitative approaches with logic, knowledge of species' biology and parsimony when interpreting findings, as a means to counter uncertainty that might occur with any single metric. We applied a sampling design that minimizes the chance of bias in detections and counts, included multiple statistical methods to test relationships, and incorporated past research and species' biology when interpreting findings. We disagree with Kroll et al. [Kroll, A.J., Runge, J.P., MacCracken, J.G., 2009. Unreliable amphibian population metrics may obfuscate more than they reveal. Biological Conservation] that the potential biases associated with the individual metrics mean that the inferences from the study are too uncertain to be useful by managers. We examined metrics that are more informative than simple site occupancy, including relative abundance, life stage distributions, and body condition, to inform our knowledge of population status. Combining metrics allows us to use readily attainable data to yield deeper insights into population structure and related spatial aspects. We agree on the value of having the most detailed and accurate data possible, but do not believe this standard should limit one to conducting only intensive experimental studies to provide detailed information on vital rates of terrestrial salamanders. The controlled experiment approach is extremely difficult and would be considerably less feasible than using population metrics to assess the status of plethodontid salamanders on forest landscapes at scales relevant to land management in the Pacific Northwest.

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

AB Despite the familiarity and economic significance of Coccinellidae, the family has thus far escaped analysis by rigorous phylogenetic methods. As a result, the internal classification remains unstable and there is no framework with which to interpret evolutionary events within the family. Coccinellids exhibit a wide range of preferred food types spanning kingdoms, and trophic levels. To provide an evolutionary perspective on coccinellid feeding preferences, we performed a phylogenetic analysis of 62 taxa based on the ribosomal nuclear genes 18S and 28S. The entire dataset consists of 3957 aligned nucleotide sites, 787 of which are parsimony informative. Bayesian and parsimony analyses were performed. Host preferences were mapped onto the Bayesian tree to infer food preference transitions. Our results indicate that the ancestral feeding condition for Coccinellidae is coccidophagy. From the ancestral condition, there have been at least three transitions to aphidophagy and one transition to leaf-eating phytophagy. A second transition to leaf-eating phytophagy arose within an aphidophagous/pollinivorous clade. The mycophagous condition in Halyziini originated from aphidophagy. Our findings suggest that polyphagy served as an evolutionary stepping stone for primarily predaceous groups to adopt new feeding habits. The analyses recovered a clade comprising Serangiini plus Microweiseini as the sister group to the rest of Coccinellidae. The subfamilies Coccinellinae and Epilachninae are monophyletic; however, Sticholotidinae, Chilocorinae, Scymninae, and Coccidulinae are paraphyletic. Our results do not support the traditional view of phylogenetic relationships among the coccinellid subfamilies. These results indicate that the current classification system poorly reflects the evolution of Coccinellidae and therefore requires revision. (C) 2009 Elsevier Inc. All rights reserved.

AB The Stethorini are unique among the Coccinellidae in specializing on mites (principally Tetranychidae) as prey. Consisting of 90 species in two genera, Stethorus and Parasthethorus, the tribe is practically cosmopolitan. The Stethorini are found in a diverse range of habitats, including many agricultural systems such as pome and stone fruits, brambles, tree nuts, citrus, avocadoes, bananas, papaya, palms, tea, cassava, maize, strawberries, vegetables, and cotton, as well as ornamental plantings, grasslands, forests, and heathlands. Tetranychid mite outbreaks became common in many agricultural systems only after World War II, when widespread use of broad-spectrum insecticides increased. Stethorini were initially appreciated only for their ability to suppress severe outbreaks of tetranychid populations. However, research on their prey searching behaviors reveals that Stethorini use visual and olfactory stimuli to locate small mite colonies in patchy distributions, and can be very effective in regulating their prey at low densities. Moreover, acariphagous coccinellids colonize mite outbreaks earlier, and consume more pest mites, than many other mite predators. Key to the use of coccinellids in conservation biological control programs is the provision of overwintering habitats and refuges from pesticides in and near cropland. When these conditions are fulfilled, Stethorini often play important roles in maintaining suppression of tetranychid populations. Examples of successful biological mite control with Stethorini include apple orchards in Pennsylvania, USA, and citrus in Asia, and the unintended disruption of a tetranychid-based biological control program for the invasive woody weed, gorse, in Australia and New Zealand. The systematics and taxonomy of this group is challenging with many cryptic species, and molecular diagnostic tools are sorely needed. How best to utilize their mite-suppressive potential in diverse settings requires better knowledge of their requirements including utilization of alternative foods, refuges for dormancy and from nonselective pesticides, and host-finding mechanisms.

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

AB We review aspects of the life histories of representative enemies of coccinellids (both entomophagous and phytophagous species) and expose both potential and real effects that they have on life parameters of their hosts. Lady beetles are attacked by a variety of natural enemies (bacteria, fungi, mites, nematodes, protozoa, wasps, flies). Few of these enemies have the ability to alter significantly the population dynamics of their hosts. This review should encourage further research to help define the role of natural enemies in the population dynamics of coccinellids. Ultimately, the conservation of beneficial lady beetles and the management of nuisance and pestiferous ones should be major emphases of research on coccinellid-natural enemy interactions.

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

AB To increase our understanding of imprinted genes in swine, we carried out a comprehensive analysis of this gene family using two complementary approaches: expression and phenotypic profiling of parthenogenetic fetuses, and analysis of imprinting by pyrosequencing. The parthenote placenta and fetus were smaller than those of controls but had no obvious morphological differences at Day 28 of gestation. By Day 30, however, the parthenote placentas had decreased chorioallantoic folding, decreased chorionic ruggae, and reduction of fetal-maternal interface surface in comparison with stage-matched control fetuses. Using Affymetrix Porcine GeneChip microarrays and/or semiquantitative PCR, brain, fibroblast, liver, and placenta of Day 30 fetuses were profiled, and 25 imprinted genes were identified as differentially expressed in at least one of the four tissue types: AMPD3, CDKN1C, COPG2, DHCR7, DIRAS3, IGF2 (isoform specific), IGF2AS, IGF2R, MEG3, MEST, NAP1L5, NDN, NNAT, OSBPL1A, PEG3, APEG3, PEG10, PLAGL1, PON2, PPP1R9A, SGCE, SLC38A4, SNORD107, SNRPN, and TFPI2. For DIRAS3, PLAGL1, SGCE, and SLC38A4, tissue-specific differences were detected. in addition, we examined the imprinting status of candidate genes by quantitative allelic pyrosequencing. Samples were collected from Day 30 pregnancies generated from reciprocal crosses of Meishan and White Composite breeds, and single-nucleotide polymorphisms were identified in candidate genes. Imprinting was confirmed for DIRAS3, DLK1, H19, IGF2AS, NNAT, MEST, PEG10, PHLDA2, PLAGL1, SGCE, and SNORD107. We also found no evidence of imprinting in ASB4, ASCL2, CD81, COMMD1, DCN, DLX5, and H13. Combined, these results represent the most comprehensive survey of imprinted genes in swine to date.

AB The recent emphasis on corn production to meet the increasing demand for bioethanol has resulted in trepidation regarding the sustainability of the global food supply. To assess the potential of alternative crops as sources of bioethanol production, we grew sweet potato (Ipomoea batatas) and cassava (Manihot esculentum) at locations near Auburn, Alabama and Beltsville, Maryland in order to measure root carbohydrate (starch, sucrose, glucose) and root biomass. Averaged for both locations, sweet potato yielded the highest concentration of root carbohydrate (ca 80%), primarily in the form of starch (ca 50%) and sucrose (ca 30%); whereas cassava had root carbohydrate concentrations of (ca 55%), almost entirely as starch. For sweet potato, overall carbohydrate production was 9.4 and 12.7 Mg ha(-1) for the Alabama and Maryland sites, respectively. For cassava, carbohydrate production in Maryland was poor, yielding only 2.9 Mg ha(-1). However, in Alabama, carbohydrate production from cassava averaged similar to 10 Mg ha(-1). Relative to carbohydrate production from corn in each location, sweet potato and cassava yielded approximately 1.5x and 1.Gx as much carbohydrate as corn in Alabama; 2.3x and 0.5x for the Maryland site. If economical harvesting and processing techniques could be developed, these data suggest that sweet potato in Maryland, and sweet potato and cassava in Alabama, have greater potential as ethanol sources than existing corn systems, and as such, could be used to replace or offset corn as a source of biofuels.

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

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

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

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

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

AB The aim of this study was to determine the effectiveness of natural flocculants to reduce solids and nutrient loads in dairy cow wastewater using solid-liquid separation: chitosan was used as a model. Its use efficiency and optimum application rate were determined using flushed dairy cow manure of varied strengths - 0.4%, 0.8%, 1.6%. and 3.2% total solids (TS) content. Treatments consisted of nine rates of chitosan. The flocculated manure was dewatered using 1-mm and 0.25-mm screens. Separation by screening alone was not effective: average efficiencies were about 60% for total suspended solids (TSS), 22% for total Kjeldahl nitrogen (TKN), and 26% for total phosphorus (TP). Mixing with chitosan before screening substantially increased separation. At optimum chitosan rate (0.5 g/L for the highest strength effluent), separation efficiencies were >95% for TSS, >73% for TKN, and >54% for TP. The results of this study indicate that natural flocculants such as chitosan are useful for the solid-liquid separation treatment of livestock wastewater. (C) 2008 Elsevier Ltd. All rights reserved.

AB Land disposal of poultry litter is an environmental concern often associated to excess phosphorus (P) in soils and potential water pollution in regions with intense poultry production. Although poultry litter can be moved off the farm and traded as fertilizer, its transportation becomes less economical with increasing distances from the farm. Thus, new litter management alternatives are needed to reduce the environmental impact of P litter application to land. This paper summarizes established and emerging alternative technologies in the U.S. that facilitate handling, concentration, and transporting of litter P. Furthermore, it examines the potential integration of technologies into poultry litter management systems that could reduce poultry litter volume and increase P content in litter by products. The adoption of alternative technologies may encourage new opportunities to produce bio-energy, fertilizer, and other valuable P byproducts from poultry litter while reducing environmental impact and promoting sustainable poultry production.

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

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

AB The fate of pesticide droplets on leaves is significantly influenced by the fine structures found on leaf surfaces. Evaporation times and the maximum coverage areas of single droplets (246, 343, 575, 762, and 886 gm) on hairy and waxy geranium leaf surfaces were determined under controlled conditions. Stereoscopic sequential images of the droplet evaporation processes were taken for five droplet sizes, three relative humidity (RH) conditions and 13 different sprays. The sprays were combinations of water, a non-ionic colloidal polymer drift retardant, an alkyl polyoxyethylene surfactant, a fungicide and three insecticides. The evaporation time and maximum coverage area of droplets were significantly changed by adding the surfactant or drift retardant to the sprays, but not by adding fungicide or insecticide. Droplet evaporation times on waxy leaves were longer than those on hairy leaves. Evaporation times increased exponentially as droplet diameter and RH increased with limited variability of regression coefficients independent of spray type and leaf surface. The maximum coverage area of droplets also increased exponentially as droplet diameter increased but it was not significantly affected by RH. On the waxy geranium leaf surfaces, the coverage area of pesticide droplets decreased throughout the evaporating process and at all RH conditions, while, on hairy leaf surfaces for the same size droplets, and at the same RH conditions, the coverage area continued to spread until evaporation was nearly completed. Given that the duration of evaporation time and the extent of the coverage area affect pesticide distribution on waxy or hairy leaves, recommendations for pesticide dosage and spray methods should be taken into account for different leaf surfaces to obtain the optimum biological effect and reduced pesticide use.

AB In subsurface bioreactors used for tile drainage systems, carbon sources are used to facilitate denitrification. The objectives of this study were to investigate the validity of first- and zero-order reactions for a laboratory-scale bioreactor, and to estimate flow and transport parameters for a laboratory-scale bioreactor. The laboratory-scale bioreactor used in this study consisted of a polyvinyl chloride (PVC) pipe (0.25 m in diameter and 6.1 m in length) filled with woodchips, with a drainage control structure attached to each end. Creek water and deionised water with NO(3)-N concentrations ranging from 8 to 33.7 mg l(-1) was passed through the bioreactor at several flow rates. For the tests with creek water, complete (100%) nitrate reduction and approximately 10-40% nitrate reduction were observed at high retention times and at low retention times, respectively. The model CXTFIT2, developed by Toride et al. (1999, Research report No. 137, U.S. Salinity Lab., ARS, USDA, Riverside, California), and an analytical solution introduced by van Genuchten and Alves (1982, Technical Bulletin No. 1661, U.S. Salinity Lab., USDA, Riverside, California) were used to investigate the assumptions that the reactions obeyed first- and zero-order kinetics. The results revealed that the assumption of first-order reaction kinetics resulted in closer agreement between the model results and the data. However, the estimated reaction terms varied over a factor of 5. These variations were not improved with the single parameter estimation. From these laboratory-scale bioreactor studies, it was concluded that the assumptions of first-order decay for nitrate transport are justified for each single run, and that woodchip-based bioreactors may be suitable for significant nutrient reduction from agricultural fields, artificially drained by tile drain systems.

TI Design of drainage culverts considering critical storm duration
SO BIOSYSTEMS ENGINEERING
LA English
DT Article
AB A method for designing road-crossing drainage culverts taking into the account critical storm duration is proposed. Based on estimated design floods, a hydraulic design approach is also proposed to optimise the dimensions and hydraulic variables of the culverts. Two small watersheds in Korea (Baran and Banweol) and thirty-five culvert design zones were used in this study. Critical storm durations were determined by applying Huff curves and unit hydrograph models such as the Nakayasu model, the United States Department of Agriculture Soil Conservation Service (USDA SCS) Curve Number model, the Clark model, and the WFRpaddy model. The American Association of State Highway and Transportation Officials (AASHTO) equation was applied to the thirty-five drainage culvert watersheds along segments of Highway No. 39 to define the optimum dimensions and hydraulic variables of the drainage culverts. The selected unit hydrograph models accurately estimated unit hydrographs for the study watersheds. Thus, the models can be considered a useful tool for computing peak runoff rates in Korean watersheds. For the other major watersheds studied, the design floods obtained by standard design were 50% greater than those calculated by the unit hydrograph models, indicating that the rational method, which is often used in culvert designs in Korea, predicts lower values than those of the standard design method. The design floods determined by the unit hydrograph models were higher than those predicted by the rational method applied in this study. Each unit hydrograph model calculated different values for double or triple rectangular-shaped culverts. With the exception of one watershed, the differences compared with the results from the standard design and AASHTO methods ranged from 0 to 10%. Consequently, implementing a design flood based on the critical storm duration is more appropriate than a design flood calculated using only the rational method. Thus, the design method using the concept of critical storm duration can be recommended to estimate a design flood. If the design method for drainage culverts developed in this research is applied to the standard design in Korea, a variety of subjective methods of estimating the design floods can be objectively achieved. Also, through incorporation of a Geographical information System (GIS), a design which considers anticipated land use changes could be achieved. (C) 2009 IAgrE. Published by Elsevier Ltd.

AB Mixed models improve the ability to detect phenotype-genotype associations in the presence of population stratification and multiple levels of relatedness in genome-wide association studies (GWAS), but for large data sets the resource consumption becomes impractical. At the same time, the sample size and number of markers used for GWAS is increasing dramatically, resulting in greater statistical power to detect those associations. The use of mixed models with increasingly large data sets depends on the availability of software for analyzing those models. While multiple software packages implement the mixed model method, no single package provides the best combination of fast computation, ability to handle large samples, flexible modeling and ease of use. Key elements of association analysis with mixed models are reviewed, including modeling phenotype-genotype associations using mixed models, population stratification, kinship and its estimation, variance component estimation, use of best linear unbiased predictors or residuals in place of raw phenotype, improving efficiency and software-user interaction. The available software packages are evaluated, and suggestions made for future software development.

AB Adult Asian long-horned beetles, Anoplophora glabripennis (Motschulsky) (Coleoptera: Cerambycidae: Lamiinae), were discovered in Ontario, Canada, in 2003 in the vicinity of a commercial warehouse. Trees were heavily scarred with signs of attack and larvae and adult beetles were common, Suggesting that there had been Multiple generations at the site. We amplified 16 microsatellite loci from 326 beetles to examine genetic diversity in this Population. Based oil Hardy-Weinberg equilibrium, 6 of 16 loci were monomorphic and 8 were not, indicating nonrandom mating. Measures of microsatellite genetic diversity and mitochondrial DNA haplotype diversity were significantly lower than those in A. glabripennis from China and Korea but were not significantly different from those in the New York City population. The proportion of different multilocus genotypes in the Ontario Population was lower than in the populations in New York City and Linden, New Jersey. These results suggest that limited genetic diversity in the Ontario population has not hampered reproduction of this invasive insect. This genetic signature is common in other invasive species, likely because a Population is founded by a few closely related individuals, or a large founding population suffers subsequent genetic bottlenecks.

Alfalfa (Medicago sativa L.) has high crude protein that is rapidly and extensively degraded in the rumen. Our objective was to develop a protocol where individual proteins could be characterized for their ruminal degradation. Proteins from individual genotypes of three alfalfa cultivars were characterized using fluorescence 2D difference gel electrophoresis combined with MALDI-TOF mass spectrometry for protein identification. Twenty-six proteins were characterized, representing between 33 and 41% of the total protein among genotypes. Variation for protein degradation was observed among proteins after 45 and 120 min of incubation in the rumen of a Holstein steer (P < 0.001). After 45 min of ruminal incubation, nine proteins averaged 75% or more remaining, 12 had 50% or less remaining, and five were intermediate. After 120 min of ruminal incubation, four proteins averaged greater than 80%, seven between 80 and 50% and 15 less than 50%, remaining. Although all proteins were degraded over time, the rate and amount of degradation was dramatically different among them. The rate of digestion differed (P = 0.05) for 3 and 10 proteins among genotypes after 45 and 120 min, respectively. Individual proteins characterized ranged in mass from 41 to 0.29% of the total mass of protein characterized. Total content of those proteins that differed for rate of digestion ranged from 7 to 1%. The results demonstrate that individual proteins can be characterized for their ruminal degradation. The ability to separate proteins based ruminal degradation suggests there is potential to select for protein that degrades more slowly and possibly escapes the rumen.

TI Effects of Impact Dehuller Rotor Speed on Dehulling Characteristics of
Diverse Oat Genotypes Grown in Different Environments
SO CEREAL CHEMISTRY
LA English
DT Article
ID MECHANICAL-BEHAVIOR; GRAIN; WEIGHT; DAMAGE
AB Commercial processing of oats for human consumption generally requires impact dehulling to isolate groats from the hull. Impact dehulling involves feeding oat grain into the center of a spinning rotor that expels the grain against the walls of the dehuller. The force of the impact breaks the hull from the groat. We have tested the effect of rotor speed oil dehulling efficiency, groat breakage, and unbroken groat yield on 18 oat genotypes from replicated plots in six different environments. Dehulling efficiency and groat breakage increased with rotor speed with all genotypes and environments, but there were significant genotypic and environmental effects as well. In general, genotypes with higher test weight and kernel density dehulled more efficiently at slower rotor speeds. Oat genotypes with higher oil and protein concentrations in their groats tended to break less during dehulling. Oats from hotter, drier environments suffered greater groat breakage. Maximal unbroken groat yield represented a balance between dehulling efficiency and groat breakage, but groat proportion and dehulling efficiency appeared to be the most important factors contributing to groat yield.

AB The purpose of this study was to determine the efficacy of extracting phenolic compounds with antioxidant activity from distillers' dried grains with solubles (DDGS) with water, 50% aqueous ethanol, and absolute ethanol, using microwave irradiation or a water bath at various temperatures. DDGS was extracted for 15 min with each solvent while heating at 23, 50, 100, and 150 degrees C by microwave irradiation or in a water bath at 23 50, and 100 degrees C. Phenolic content of extracts increased with increasing temperature to a maximum of 12.02 mg/g in DDGS extracts that were microwave irradiated in water or with 50% aqueous ethanol at 150 degrees C. Antioxidant activity range was 1.49-6.53 mu mol of Trolox equivalents/g of DDGS. Highest antioxidant activities were obtained from 50% aqueous ethanol extracts at all temperatures, and water extracts that were heated at 100 and 150 degrees C. These data indicate that DDGS extracts with high phenolic content and antioxidant activity can be obtained from DDGS, particularly with the use of water or 50% ethanol and high temperature (100 or 150 degrees C). This may be valuable to ethanol manufacturers, livestock producers, and food and nutraceutical companies.

AB Researchers and practitioners have long utilized a variety of penetrometers to investigate the snowpack. Identifying definitive relationships between penetrometer-derived microstructural information and stability has been challenging. The purpose of this study is two-fold: 1. We propose a simple field test to establish relationships between load and penetrometer-derived microstructural estimates. 2. We utilize the SnowMicroPen (SMP) to quantify changes in weak layer residual strength and microstructural dimension associated with an artificial loading event Our dataset is from Moonlight Basin, Montana and includes three modified loaded-column tests, each paired with 5 SMP profiles. Depth hoar comprised the targeted weak layer. Results indicate that loading caused the residual strength and rupture frequency to decrease significantly. Much like a compression test at a micro-scale, the force required for the SMP to rupture individual structures as well as the micro-scale strength decreased significantly when the slab stress was increased by artificially adding blocks of snow. A decrease in observed rupture frequency within the weak layer (or an increase in the distance between ruptured structures) also occurred after the loading event. probably because some structures within the weak layer had already failed or were so close to failing that the penetrometer could not detect their rupture. Due in part to the large difference in loads, microstructural differences between the natural and loaded columns were significant enough that only one profile would have been necessary to determine a significant difference in residual strength. Artificial removal of slab stress resulted in greater rupture forces and larger microstructures, likely due to elastic rebound. (C) 2009 Elsevier B.V. All rights reserved.

ID STABILITY
AB The Extended Column Test (ECT) is a new stability test that aims to assess the fracture propagation potential across a 0.90 m wide isolated column. This paper: 1) describes the test procedure and presents new recording standards for the test, 2) uses two independent datasets (each consisting of over 300 tests) to assess the effectiveness of the test, 3) looks at the spatial variability of ECT results from several test grids. and 4) compares adjacent results between the ECT and the Propagation Saw Test (PST) on stable and unstable slopes. Our results indicate that the ECT is an effective stability test, with a false-stability rate less than other standard snow stability tests. Results are sometimes quite spatially uniform, though occasionally slopes may exhibit variable ECT results. In comparison to the PST, our data suggest that the ECT has a lower false-stability rate, but a higher false instability rate. Overall, the ECT is better at discriminating between stable and unstable slopes in our dataset. No test is perfect and all tests must be used in conjunction with additional data, but our results show that the ECT is valuable additional tool for assessing snow stability.

AB Medaka (Oryzias latipes) embryos at different developmental stages were exposed to ethanol for 48 h, then allowed to hatch. Teratogenic effects were evaluated in hatchlings after examining chondrocranial cartilage deformities. Ethanol disrupted cartilage development in medaka in a dose and developmental stage-specific manner. Compared to controls, the linear length of the neurocranium and other cartilages were reduced in ethanol-treated groups. Moreover, the chondrification in cartilages, specifically trabeculae and polar cartilages, were inhibited by ethanol. To understand the mechanism of ethanol teratogenesis, NAD(+): NADH status during embryogenesis and the methylation pattern of Aldh1A2 promoter in whole embryos and adult tissues (brain, eye; heart and liver) were analyzed. Embryos 6 dpf had higher NAD(+) than embryos 0 or 2 dpf. Ethanol (200 or 400 mM) was able to reduce NAD(+) content in 2 and 6 dpf embryos. However, in both cases reductions were not significantly different from the controls. Moreover, no significant difference in either NADH content or in NAD(+): NADH status of the ethanol-treated embryos, with regard to controls, was observed. The promoter of Aldh1A2 contains 31 CpG dinucleotides (-705 to + 154, ATG = + 1); none of which were methylated. Compared to controls, embryonic ethanol exposure (100 and 400 mM) was unable to alter Aldh1A2 promoter methylation in embryos or in the tissues of adults (breeding) developmentally exposed to ethanol (300 mM, 48 hpf). From these data we conclude that ethanol teratogenesis in medaka does not induce alteration in the methylation pattern of Aldh1A2 promoter, but does change cartilage development.

AB A high-speed, low-cost, image-based sorting device was developed to detect and separate grains having slight color differences or small defects. The device directly combines a complementary metal-oxide-semiconductor (CMOS) color image sensor with a field-programmable gate array (FPGA) which was programmed to execute image processing in real-time, without the need of an external computer. Spatial resolution of the imaging system is approximately 16 pixels/mm. The system includes three image sensor/FPGA combinations placed around the perimeter of a single-file stream of kernels, so that most of the surface of each kernel is be inspected. A vibratory feeder feeds kernels onto an inclined chute that kernels slide down in a single-file manner. Kernels are imaged immediately after dropping off the end of the chute and are diverted by activating an air valve. The system has a throughput rate of approximately 75 kernels/s per channel which is much higher than previously developed image inspection systems. This throughput rate corresponds to an inspection rate of approximately 8 kg/h of wheat and 40 kg/h of popcorn. The system was initially developed to separate white wheat from red wheat, and to remove popcorn having blue-eye damage, which is indicated by a small blue discoloration in the germ of a popcorn kernel. Testing of the system resulted in accuracies of 88% for red wheat and 91% for white wheat. For popcorn, the system achieved 74% accuracy when removing popcorn with blue-eye damage and 91% accuracy at recognizing good popcorn. The sorter should find uses for removing other defects found in grain, such as insect-damaged grain, scab-damaged wheat, and bunted wheat. Parts for the system cost less than $2000, suggesting that it may be economical to run several systems in parallel to keep up with processing plant rates. Published by Elsevier B.V.
