TI Penicillium astrolabium and Penicillium neocrassum, two new species isolated from grapes and their phylogenetic placement in the P-olsonii and P-brevicompactum clade SO MYCOLOGIA LA English DT Article DE DNA sequences; fungi; grapes; taxonomy ID SECTION NIGRI; METABOLITES; FUNGI AB We describe two new terverticillate Penicillium species isolated from grapes on the basis of phenotypic and phylogenetic differences from known species. The strains were isolated in the course of a study to establish the mycobiota of grapes in Portugal. Penicillium astrolabium is phenotypically similar to P. olsonii but differs from it by two cultural characters, growth rates and the colony reverse color. P. neocrassum is similar to P. brevicompactum but is readily distinguished by sclerotia production. Phylogenetically P. astrolabium and P. neocrassum are placed respectively in the P. olsonii and P. brevicompactum clade. Multilocus analysis confirmed the genetic distinctiveness of both species. The parsimony trees obtained for ITS-lsu rDNA region and two protein coding genes, calmodulin and P-tubulin, show congruence for all the species in the Olsonii series: P. brevicompactum, P. bialowiezense, P. olsonii, P. astrolabium and P. neocrassum, indicating that these taxa are genetically well isolated.

Perithecia of G. intermedia developed in vitro on colonies of D. betulina isolated from birch tissues in late summer, and single ascospores of G. intermedia consistently developed into colonies similar to D. betulina, producing typical D. betulina conidia. isolates of D. betulina could be grouped into two mating types, which produced fertile perithecia of G. in termedia when mated with each other. Mycelia from single-ascospore and single-conidial isolates were inoculated onto shoots of downy birch, causing lesions and die-back from which D. betulina was consistently isolated. ITS region ribosomal DNA sequence analysis confirmed the results of the morphological and mating studies, and found that the closest known relatives of G. intermedia/D. betulina are Gnomoniella nana and Sirococcus clavigignenti-juglandacearum. The conclusion from these studies is that D. betulina is the anamorph of G. intermedia. Published by Elsevier Ltd on behalf of The British Mycological Society.

'Azul' in the State of Jalisco, Mexico. Nine of these isolates produced nonvolatile metabolites that completely inhibited the growth of Thielaviopsis paradoxa on potato dextrose agar plates. These isolates were identified as Trichoderma longibrachiatum on the basis of their morphology and DNA sequence analysis of two genes (ITS rDNA and translation elongation factor EF-1 alpha). Mycoparasitism of Th. paradoxa by T. longibrachiatum strains in dual cultures was examined by scanning electron microscopy. The Trichoderma hyphae grew alongside the Th. paradoxa hyphae, but penetration of Thielaviopsis hyphae by Trichoderma was no apparent. Aleurioconidia of Th. paradoxa were parasitized by Trichoderma. Both hyphae and aleurioconidia of Th. paradoxa lost turgor pressure, wrinkled, collapsed and finally disintegrated. In liquid cultures, all nine Trichoderma isolates produced proteases, beta-1,3-glucanases and chitinases that would be responsible for the degradation of Thielaviopsis hyphae. These results demonstrate that the modes of action of T. longibrachiatum involved against Th. paradoxa in vitro experiments are mycoparasitism and the production of nonvolatile toxic metabolites.

A novel bio-functional nanosensor for Salmonella detection was developed using hetero-nanorods. The silica nanorods were fabricated by glancing angle deposition method and the gold was sputtered onto the silica nanorods. Alexa488-succinimide dye was immobilized onto the annealed Si nanorods via the attachment between dye ester and primary amine group supplied by the 3-Aminopropyltriethoxysilane. The anti-Salmonella was conjugated to gold via Dithiobis[succinimidylpropionate] self-assembly monolayer. Due to the high aspect ratio nature of the Si nanorods, hundreds or thousands of dye molecules attached to the Si nanorods produced enhanced fluorescence signal. These biologically functionalized. nanorods can be used to detect Salmonella with fluorescent microscopic imaging. This new nanoscale biosensor will be able to detect other foodborne pathogenic bacteria for food safety and security applications.

Such protein cross-links, which contain dityrosine, can also occur when proteins are treated with peroxidase (POD). Previously, we have shown that the allergenic properties of peanut allergens are reduced after treatment with POD (Chung et al., 2004). We hypothesized in this study that Cu(2+)/H(2)O(2) can also reduce peanut allergenicity, because Cu(2+)/H(2)O(2) produces the same cross-links (containing dityrosine) as POD. To support our hypothesis, extracts from raw and roasted peanuts were treated with and without Cu(2+)/H(2)O(2) at pH 7 for 5 hrs at 37 degrees C. The samples were then analyzed by SDS-PAGE, Western blots, and competitive inhibition ELISA, in which immunoglobulin E (IgE) antibodies from a pooled serum of peanut-allergic individuals were used. Also, a monoclonal antibody against dityrosine was used to detect dityrosine-containing cross-links. Results showed that only roasted peanuts were affected by Cu(2+)/H(2)O(2). In this case, levels of two peanut major allergens, Ara h 1 and Ara h 2, were reduced, and cross-links were formed. IgE binding, overall, was lower despite some binding of IgE to cross-links. Cross-links were recognized by the monoclonal antibodies against dityrosine. We concluded that Cu(2+)/H(2)O(2) reduced peanut allergenicity by inducing the decrease and cross-linking of peanut allergens. The implication of this finding is that it could lead to future development of hypoallergenic peanut products.

However, the presence of ricin toxin and hyper-allergenic 2S albumins in seed poses health concern during its cultivation and processing. Aspart of agenetic approach to eliminate ricin and 2S albumins from castor, we have investigated the expression of ricin and 2S albumin genes during seed development. Northern analyses showed that the ricin mRNA levels increased significantly during the middle and late stages of seed development, whereas 2S albumin mRNA accumulated transiently in the middle stages of seed development. The different temporal patterns between ricin and 2S albumin genes indicate distinct regulatory mechanisms involved in their respective gene expression. We further examined. the similarities of castor 2S albumins to those from different plant species, including their phylogenetic relationship, common amino acid domains and possible secondary biological functions.

Flax (Linum usitatissimum L.) fiber offers many possibilities towards this goal. Specific United States Department of Agriculture (USDA) research objectives are to: (1) evaluate traditional farm equipment for flax production, (2) improve retting, especially through use of enzymes, (3) develop objective standards for fiber quality testing, and (4) test fibers for manufacturing performance and/or aesthetic properties. Fiber flax for short staple uses can be rapidly harvested by equipment readily available on US farms. Warm southern climates allow this crop to be grown in the winter to produce flax on traditionally dormant fields. Enzymes to extract fibers provide an environmentally friendly method for reliable and sustainable agriculture. Commercial enzymes and calcium chelating agents provide a key step in the economic development of a controlled and scientific approach to efficiently produce fibers of high and consistent quality. A USDA Flax Pilot Plant based on commercially available equipment provides better understandings of fiber quality parameters, fiber standards, processing costs, and eliminates uncertainties of raw material supply. ASTM International standards are being developed to judge flax fiber for quality related to processing and marketing decisions. Flax fiber blended with cotton and spun by vortex, rotor, and ring-spinning equipment at the Cotton Quality Research Station (CQRS), ARS-USDA, provide a final stage of evaluation.

Disruption of PrPC expression in mice, a species that does not naturally contract prion diseases, results in no apparent developmental abnormalities(2-5). However, the impact of ablating PrPC function in natural host species of prion diseases is unknown. Here we report the generation and characterization of PrPC-deficient cattle produced by a sequential gene-targeting system(6). At over 20 months of age, the cattle are clinically, physiologically, histopathologically, immunologically and reproductively normal. Brain tissue homogenates are resistant to prion propagation in vitro as assessed by protein misfolding cyclic amplification(7).

With the chemical reduction of any dehydroascorbate (DHA) in a sample, total ascorbate can be assayed using the alpha-alpha'-bipyridl method, and DHA can be estimated by subtracting the reduced portion from the total ascorbate pool. The assay is performed in microcentrifuge tubes and assessed in a 96-well plate reader. Reduced ascorbate, DHA and total ascorbate of at least 64 experimental samples can be analyzed easily in 1 d.

TI Estimation of total phenolic content and other oxidation substrates in plant tissues using Folin-Ciocalteu reagent SO NATURE PROTOCOLS LA English DT Article ID PHENYLPROPANOID METABOLISM; ANTIOXIDANT CAPACITY; OZONE AB Non-structural phenolic compounds perform a variety of functions in plants, including acting as antioxidants. We describe a microplate-adapted colorimetric total phenolics assay that utilizes Folin-Ciocalteu (F-C) reagent. The F-C assay relies on the transfer of electrons in alkaline medium from phenolic compounds to phosphomolybdic/phosphotungstic acid complexes, which are determined spectroscopically at 765 nm. Although the electron transfer reaction is not specific for phenolic compounds, the extraction procedure eliminates approximately 85% of ascorbic acid and other potentially interfering compounds. This assay is performed in microcentrifuge tubes and assessed in a 96-well plate reader. At least 64 samples can be processed in 1 d.

AB Six geographically diverse cultivars of rye (Secale cereale), a wheat (Triticum aestivum) cultivar and hairy vetch (Vicia villosa) cultivar unstated were screened for Meloidogyne incognita host suitability. Chemical constituents of rye can suppress M. incognita, so the rye cultivars and wheat were also tested for benzoxazinoid content to determine if rye cultivar selection could be based upon plant chemistry. There was variation in M. incognita host status among the rye cultivars. Cultivars Aroostook, Elbon, Oklon and Wrens Abruzzi were the most resistant rye cultivars, with low numbers of M. incognita eggs/g dry root. Cultivar Wheeler had somewhat more eggs/g root than these cultivars, while cv. Merced supported nearly three times more eggs/g root than cv. Wheeler. Most of the rye cultivars were similar to each other in total benzoxazinoid content, although cv. Aroostook had the lowest amount of total benzoxazinoids. When data from roots and shoots were combined, more than 79% of the total benzoxazinoids in all six of the rye cultivars were comprised of the non-methoxy-substituted forms: i) (2R)-2-beta-D-glucopyranosyloxy-4-hydroxy-(2H)1,4-benzoxazin-3(4H)-one (DIBOA-glucoside); ii) 2,4-dihydroxy-(2H)-1,4-benzoxazin-3(4H)-one (DIBOA); and iii) benzoxazolin-2(3H)-one (BOA). In the rye cultivar roots there was little difference among cultivars in amounts of the methoxy-substituted benzoxazinoids: i) (2R)-2-beta-D-glucopyranosyloxy-4-hydroxy-7-methoxy-(2H)-1,4-benzoxazin-3(4H)-one (DIMBOA-glucoside); ii) 2,4-hydroxy-7-methoxy-(2H)-1,4-benzoxazin-3(4H)-one (DIMBOA); iii) 6-methoxy-benzoxazolin-2(3H) -one (MBOA); and iv) 2hydroxy-7-methoxy-(2H)-1,4,-benzoxazzin-3(4H)-one (HMBOA). However, cv. Aroostook roots had the lowest concentration of nonmethoxy-substituted benzoxazinoids. Rye cultivars were generally similar to each other in amounts of benzoxazinoids in shoots. The shoots had much lower concentrations of methoxy-substituted benzoxazinoinds than the roots but much higher concentrations of nonmethoxy-substituted forms. Cultivars with the lowest numbers of eggs/g root and the highest amounts of benzoxazinoids (with potential for action against nematodes in soil after incorporation as a green manure) are possible candidates for optimal nematode management.

In separate microplot studies, NVS was applied either alone at different rates (0, 25, 50, 75, 100 dry t ha(-1)), or in combination with M. incognita-resistant and M. incognita-susceptible cultivars, to different M. incognita initial densities (0, 37 500, 75 000 eggs/microplot). NVS suppressed M. incognita. During year 1, increasing rates of NVS resulted in higher soil solution pH and greater M. incognita J2 and egg suppression. Soil solution pH remained higher in NVS-amended plots compared to the unamended control in years 2 and 3. NVS was more effective in reducing moderate than in reducing high initial nematode populations, with 94-100% reduction in egg and juvenile populations compared to 75-79%, respectively. In all experiments, a reduction in nematode populations by NVS, alone or in combination with a resistant cultivar, did not occur consistently in years 2 or 3. Unfortunately, the application rate of NVS required to achieve this reduction in nematode populations is probably not agronomically realistic. Additional research may allow the rate of NVS required to suppress plant-parasitic nematodes to be reduced. C1 USDA ARS, Nematol Lab, Beltsville, MD 20705 USA.

A compendium of the most important diagnostic characters for use in identification of species is included as a practical alternative and supplement to the key. The diagnosis of Merlinius is emended and a list of all valid species of the genus is given. The characters most useful for separating species include body and stylet lengths, shape of head, tail and tail terminus, number of head and tail annules, position of vulva (V), and c' ratio in females. Also useful are length and shape of spicules and gubernacula in males. A new stunt nematode, Merlinius khuzdarensis n. sp., from the rhizosphere of date palm (Phoenix dactylifera L.) from Khuzdar, Balochistan Province, Pakistan, is described and illustrated. This new species resembles M. bavaricus, M. communicus, M. bilqeesae and M. montanus, but differs from these species by the following: body and stylet length, shape of head, tail and tail terminus, number of head and tail annules, and position of phasmids. Because this species is limited in distribution, its economic importance in date palm and other cultivated crops within the region is not known.

Methods: We have previously described genetic dopamine-deficient mouse models which lack the ability to synthesize dopamine. Because these animals require daily treatment with 3,4-L-dihydroxyphenylalanine (L-dopa) to survive, it has not been possible to examine the consequences of chronic loss of dopamine on pituitary physiology. We use viral-mediated gene transfer to selectively restore dopamine to the dorsal striatum of dopamine-deficient mice which allows the mice to survive without L-dopa. Results: We find that mice chronically lacking tuberoinfundibular dopamine secrete large amounts of prolactin due to the development of severely enlarged pituitaries composed principally of hyperplastic hypertrophic lactotrophs and multifocal prolactinomas. In addition, these mice have elevated serum growth hormone levels and aged males develop hypertrophy of the seminal vesicles. Conclusion: Our observations are consistent with the hypothesis that hypothalamic dopamine is a critical inhibitor of lactotroph proliferation and suggest additional roles for dopamine in the regulation of pituitary function.

This study examined which demographic groups were affected and whether there were any changes in medical care that might explain the decrease. Methods: Information about hospitalizations for GBS was obtained from the 1993 - 2004 annual Nationwide Inpatient Sample and used to estimate hospitalization rates and the medical characteristics of hospitalized GBS patients. Results: The GBS hospitalization rate decreased 20.1% (95% CI 18.3 - 21.9%) between 1993 and 2004. Most groups were affected by the decrease except persons aged 18 - 44 years. There were several changes in medical care during the period, including a reduction in interhospital transfers and a shift from plasmapheresis to intravenous immunoglobulin ( IVIg) therapy. Conclusions: The reduction in transfers accounted for about one-fourth of the decrease in the GBS hospitalization rate, and may have been related to the shift from plasmapheresis to IVIg therapy. The other causes of the decrease are unknown. C1 USDA, Serv Econ Res, Washington, DC 20036 USA. RP Frenzen, PD (reprint author), USDA, Serv Econ Res, 1800 M St,NW, Washington, DC 20036 USA.

The abundance of AM fungi (AMF) was estimated in maple (Acer spp.) fine roots following more than a decade of experimental additions of N designed to simulate chronic atmospheric N deposition. Abundance of AMF was measured by staining and ocular estimation, as well as by analyzing for the AMF indicator fatty acid 16:1 omega 5c in phospholipid (biomass indicator) and neutral lipid (lipid storage indicator) fractions. Arbuscular mycorrhizal fungal biomass, storage structures and lipid storage declined in response to N addition measured by both methods. This pattern was found when AM response was characterized as colonization intensity, on an areal basis and in proportion to maple above-ground biomass. The phospholipid fraction of the fatty acid 16:1 omega 5c was positively correlated with total AMF colonization and the neutral lipid fraction with vesicle colonization. Decreased AMF abundance with simulated N deposition suggests reduced C allocation to these fungi or a direct soil N-mediated decline. The fatty acid (phospholipid and neutral lipid fractions) 16:1 omega 5c was found to be a good indicator for AMF active biomass and stored energy, respectively.

The techniques used in collecting the data from which its parameters are estimated have been the object of extensive optimization, but the statistical aspects of estimation have not received the same attention. The model segments assimilation into three regions, each modeled by a distinct function. Three parameters of the model, namely the maximum rate of Rubisco carboxylation (V-c max), the rate of electron transport (J), and nonphotorespiratory CO2 evolution (R-d), are customarily estimated from gas exchange data through separate fitting of the component functions corresponding to the first two segments. This disjunct approach is problematic in requiring preliminary arbitrary subsetting of data into sets believed to correspond to each region. It is shown how multiple segments can be estimated simultaneously, using the entire data set, without predetermination of transitions by the investigator. Investigation of the number of parameters that can be estimated in the two-segment model suggests that, under some conditions, it is possible to estimate four or even five parameters, but that only V-c max, J, and R-d, have good statistical properties. Practical difficulties and their solutions are reviewed, and software programs are provided. C1 USDA, Agr Res Serv, Plant Sci Res Unit, Raleigh, NC 27607 USA.

Thlaspi caerulescens plants were grown hydroponically on both high and low Zn and Cd regimes and whole-shoot and -root metal accumulation, and root Cd-109(2+) influx were determined. High-Zn-grown (500 mu m Zn) plants were found to be more Cd-tolerant than plants grown in standard Zn conditions (1 mu m Zn). Furthermore, shoot Cd accumulation was significantly greater in the high-Zn-grown plants. A positive correlation was also found between shoot Zn accumulation and increased plant Cd status. Radiotracer Cd-109 root flux experiments demonstrated that high-Zn-grown plants maintained significantly higher root Cd2+ influx than plants grown on 1 mu m Zn. It was also found that both nickel (Ni) and copper (Cu) shoot accumulation were stimulated by high plant Zn status, while manganese (Mn) accumulation was not affected.

On the basis of one such comparison, it was argued that model projections of future food supply (some of which are based on older enclosure data) may have significantly overestimated the positive effect of elevated CO2 concentration on crop yields and, by extension, food security. However, in the comparison, no effort was made to differentiate 'enclosure study' methodologies with respect to maintaining projected CO2 concentration or to consider other climatic changes (e.g. warming) that could impact crop yields. In this review, we demonstrate that relative yield stimulations in response to future CO2 concentrations obtained using a number of enclosure methodologies are quantitatively consistent with FACE results for three crops of global importance: rice (Oryza sativa), soybean (Glycine max) and wheat (Triticum aestivum). We suggest, that instead of focusing on methodological disparities per se, improved projections of future food supply could be achieved by better characterization of the biotic/abiotic uncertainties associated with projected changes in CO2 and climate and incorporation of these uncertainties into current crop models.

Here, metal co-tolerance, accumulation and localization were investigated for A. murale exposed to metal co-contaminants. A. murale was irrigated with Ni-enriched nutrient solutions containing basal or elevated concentrations of cobalt (Co) or zinc (Zn). Metal localization and elemental associations were investigated in situ with synchrotron X-ray microfluorescence (SXRF) and computed-microtomography (CMT). A. murale hyperaccumulated Ni and Co(> 1000 mu g g(-1) dry weight) from mixed-metal systems. Zinc was not hyperaccumulated. Elevated Co or Zn concentrations did not alter Ni accumulation or localization. SXRF images showed uniform Ni distribution in leaves and preferential localization of Co near leaf tips/margins. CMT images revealed that leaf epidermal tissue was enriched with Ni but devoid of Co, that Co was localized in the apoplasm of leaf ground tissue and that Co was sequestered on leaf surfaces near the tips/margins. Cobalt-rich mineral precipitate(s) form on leaves of Co-treated A. murale. Specialized biochemical processes linked with Ni (hyper)tolerance in A. murale do not confer (hyper)tolerance to Co. A. murale relies on a different metal storage mechanism for Co (exocellular sequestration) than for Ni (vacuolar sequestration). C1 Univ Delaware, Newark, DE 19716 USA.

Here, hourly to seasonal patterns of stem growth and sap flow velocity were examined in mature trees from a mixed deciduous forest in eastern Tennessee (USA) to evaluate the effects of variations in ambient O-3 exposure and climate on patterns of stem growth and water use. Ambient O-3 caused a periodic slowdown in seasonal growth patterns that was attributable in part to amplification of diurnal patterns of water loss in tree stems. This response was mediated by statistically significant increases in O-3-induced daily sap flow and led to seasonal losses in stem growth of 30-50% for most species in a high-O-3 year. Decreased growth and increased water use of mature forest trees under episodically high ambient O-3 concentrations suggest that O-3 will amplify the adverse effects of increasing temperatures on forest growth and forest hydrology.

Patterns of sap flow in stems and soil moisture in the rooting zones of mature trees, coupled with late-season streamflow in three forested watersheds in east Tennessee, USA, were analyzed to determine relative influences of ozone and other climatic variables on canopy physiology and streamflow patterns. Statistically significant increases in whole-tree canopy conductance, depletion of soil moisture in the rooting zone, and reduced late-season streamflow in forested watersheds were detected in response to increasing ambient ozone levels. Short-term changes in canopy water use and empirically modeled streamflow patterns over a 23-yr observation period suggest that current ambient ozone exposures may exacerbate the frequency and level of negative effects of drought on forest growth and stream health.

The DAYCENT ecosystem model was parametrized to simulate the impact of elevated CO2 at the open-top chamber (OTC) experiment in north-eastern Colorado (1996-2001), and was also used to simulate the projected ecosystem impact of the PHACE experiments during the next 10 yr. Model results suggest that soil water content, plant production, soil respiration, and nutrient mineralization will increase for the high-CO2 treatment. Soil water content will decrease for all years, while nitrogen mineralization, soil respiration, and plant production will both decrease and increase under warming depending on yearly differences in water stress. Net primary production (NPP) will be greatest under combined warming and elevated CO2 during wet years. Model results are consistent with empirical field data suggesting that water and nitrogen will be critical drivers of the semiarid grassland response to global change.

Foliage at the same height in the canopy on paired O-3-sensitive and -insensitive cutleaf coneflowers was assessed for level of foliar symptoms, stomatal density, stomatal responsiveness to dynamic changes in light and leaf-to-air vapor pressure deficit (VPD), steady-state responses to light and CO2, intrinsic transpirational efficiency, and plant water balance. There were no morphological differences between the sensitivity types that might have contributed to greater O-3 uptake in sensitive individuals. Stomata of sensitive plants were less responsive than those of insensitive plants to experimentally increased and decreased light intensities, and to increased VPD. O-3-insensitive plants had greater intrinsic transpirational efficiencies, greater maximum assimilation rates under saturating CO2 and light, and greater carboxylation rates. Different physiological attributes vary independently within an individual plant, which collectively confer sensitivity or insensitivity to O-3 injury.

We transplanted the two parental ecotypes and experimental F2 hybrids into six field sites, and collected morphological, phenological and fitness data on emergent plants. To focus on edaphically mediated selection, rather than on pollinator-mediated selection, we used pollinator-exclusion cages. Transplanted parentals of the two ecotypes showed genetic differentiation for floral traits, but not for phenological traits or cotyledon size. For the F2 hybrids growing on serpentine soils, there was significant directional selection on cotyledon size, flower size and flower shape. However, the pattern of selection did not differ significantly between serpentine and nonserpentine sites. Overall, we did not see evidence for divergent selection on the two soil types. We conclude that differences in floral traits between the ecotypes do not reflect adaptation to physical conditions associated with soil type, and that there are unmeasured traits that must be contributing to ecotypic differentiation.

Increasing atmospheric [CO2], increasing temperature, elevated nitrogen deposition and intensified management will change this C store. Well documented single-factor responses of net primary production are: higher photosynthetic rate (the main [CO2] response); increasing length of growing season (the main temperature response); and higher leaf-area index (the main N deposition and partly [CO2] response). Soil organic matter will increase with increasing litter input, although priming may decrease the soil C stock initially, but litter quality effects should be minimal (response to [CO2], N deposition, and temperature); will decrease because of increasing temperature; and will increase because of retardation of decomposition with N deposition, although the rate of decomposition of high-quality litter can be increased and that of low-quality litter decreased. Single-factor responses can be misleading because of interactions between factors, in particular those between N and other factors, and indirect effects such as increased N availability from temperature-induced decomposition. In the long term the strength of feedbacks, for example the increasing demand for N from increased growth, will dominate over short-term responses to single factors. However, management has considerable potential for controlling the C store. C1 Swedish Univ Agr Sci, Dept Ecol & Environm Res, SLU, SE-75007 Uppsala, Sweden.

Phytoavailable Ni in soil amended with biomass declined rapidly over time due to Ni binding to iron (Fe)/manganese (Mn) oxides in the soil. No significant effects on seed germination were observed. Unlike the Ni complex in Alyssum biomass, more Ni remained soluble and phytoavailable in soil amended with Ni(NO3)(2), thus significantly inhibiting seed germination. High-Ni leaves shed by hyperaccumulators did not appear to create a 'toxic zone' around the plants and inhibit germination or growth of competing plants. The lack of an allelopathic effect was probably related to low Ni availability. C1 Univ Georgia, Coll Agr & Environm Sci, Athens, GA 30602 USA.

Our transgenic aspen lines expressed low stem lignin concentration but normal cellulose concentration, low lignin stem concentration with high cellulose concentration or an increased stem syringyl to guaiacyl lignin ratio. Large differences in stem lignin concentration observed across lines were not observed in leaves or fine roots. Nonetheless, low lignin lines accumulated 15-17% less root C and 33-43% less new soil C than the control line. Compared with the control line, transformed aspen expressing high syringyl lignin accumulated 30% less total plant C - a result of greatly reduced total leaf area - and 70% less new soil C. These findings suggest that altered stem lignin biosynthesis in Populus may have little effect on the chemistry of fine roots or leaves, but can still have large effects on plant growth, biomass partitioning and soil C formation.

We incorporated soil/plant biophysical properties into a simple model based on Darcy's law to predict seasonal trajectories of HR. We investigated the spatial and temporal variability of HR across multiple years in two old-growth coniferous forest ecosystems with contrasting species and moisture regimes by measurement of soil water content (theta) and water potential (Psi) throughout the upper soil profile, root distribution and conductivity, and relevant climate variables. Large HR variability within sites (0-0.5 mm d(-1)) was attributed to spatial patterns of roots, soil moisture and depletion. HR accounted for 3-9% of estimated total site water depletion seasonally, peaking at 0.16 mm d(-1) (ponderosa pine; Pinus ponderosa) or 0.30 mm d(-1) (Douglas-fir; Pseudotsuga menziesii), then declining as modeled pathway conductance dropped with increasing root cavitation. While HR can vary tremendously within a site, among years and among ecosystems, this variability can be explained by natural variability in Psi gradients and seasonal courses of root conductivity.

TI A comparison of predictions made by three simulation models of foot-and-mouth disease SO NEW ZEALAND VETERINARY JOURNAL LA English DT Article DE foot-and-mouth disease; simulation; animal disease modelling; validation ID UNITED-KINGDOM; GREAT-BRITAIN; UK FOOT; EPIDEMIC; OUTBREAK; SPREAD AB AIMS: To describe results of a relative validation exercise using the three simulation models of foot-and-mouth disease (FMD) in use by the quadrilateral countries (QUADS; Australia, Canada, New Zealand, and United States of America; USA). METHODS: A hypothetical population of farms was constructed and, following the introduction of an FMD-like disease into a single farm, spread of disease was simulated using each of the three FMD simulation models used by the QUADS countries. A series of 11 scenarios was developed to systematically evaluate the key processes of disease transmission and control used by each of the three models. The predicted number of infected units and the size of predicted outbreak areas for each scenario and each model were compared using the Kruskal-Wallis test. Agreement among the three models in terms of geographical areas predicted to become infected were quantified using Fleiss' Kappa statistic. RESULTS: Although there were statistically significant differences in model outputs in terms of the numbers of units predicted to become infected, the temporal onset of infection throughout the simulation period, and the spatial distribution of infected units, these differences were generally small and would have resulted in the same (or similar) management decisions being adopted in each case. CONCLUSIONS: Agreement among the three models in terms of the numbers of premises predicted to become infected, the temporal onset of infection throughout the simulation period, and the spatial distribution of infected premises provides evidence that each of the model developers are consistent in their approach to simulating the spread of disease throughout a population of susceptible individuals. This consistency implies that the assumptions taken by each development team are appropriatewhich in turn serves to increase end-user confidence in model predictions. CLINICAL RELEVANCE: Relative validation is one of a number of steps that can be undertaken to increase end-user confidence in predictions made by infectious disease models.

A method was developed earlier that would estimate the MC of a small sample of in-shell peanuts (peanut pods) held between two circular parallel-plates, from the measured values of capacitance and phase angle at two frequencies 1 and 5 MHz. These values were used in an empirical equation, developed using the capacitance and phase angle values of samples of known MC levels, to obtain the average MC values of peanut samples with moisture contents in the range of 7 to 18%. In the present work, two rectangular parallel-plates were mounted inside a vertical cylinder made of acrylic material and filled with about 100 g of in-shell peanuts and their average mc was determined from a similar empirical equation. The calculated MC values were compared with those obtained by the standard air-oven method. For over 85% of the samples tested in the moisture range between 6% and 22% the MC values were found to be within 1% of the air-oven values. Ability to determine the average MC of slightly larger quantities of in-shell peanuts without shelling and cleaning them, as being done presently, will save time, labor and sampling material for the peanut industry.

Although current selection efforts are based on growth and disease resistance, stress responsiveness is also a concern. Previous work has shown that heritable differences in stress response can be identified by measuring blood levels of cortisol after exposure to a 3-h crowding stress. We characterized this stress response and measured plasma glucose concentrations in 64 of our broodstock families. We found the method reliable for identifying differences in this stress response. Values for both cortisol and glucose response were similar for replicates of families. The size of the fish within the range examined and the sex of the animals, which were reproductively immature, did not appear to affect response. Variation in poststressor plasma cortisol and glucose was observed among families (11.6-93.9 ng cortisol/mL and 5.2-10.9 mM glucose) and individuals. The cortisol and glucose responses to the stressor were not correlated. Resting and poststressor plasma cortisol concentrations were significantly correlated among families, but glucose concentrations were not. Survival rate was 70% and there was no association between survival and poststressor cortisol or glucose concentration. There was a significant positive association between cortisol response and growth performance. and mean plasma cortisol concentrations in response to the stress challenge were significantly greater for families selected for faster growth rate than for those not selected.

These levels often exceed those found to be lethal to sunshine bass. We compared the effects of organic fertilizer only, both organic and inorganic fertilizer, and both organic and inorganic fertilizers with sodium bicarbonate on 0.04-ha culture ponds. Rice bran, the organic fertilizer, was applied at 278 kg/ha during the first week and 55.6 kg/ha during the second week. Liquid 9-27-0 NPK (urea and mono-ammonium phosphate), the inorganic fertilizer, was applied at 48 kg/ha during both weeks. Sodium bicarbonate was applied at 56, 112, or 224 kg/ha. Primary productivity, pH. and the concentrations of ammonia, chlorophyll a, phytoplankton, and zooplankton were compared among treatments. We include results from the 12-14 d after ponds were filled and fertilized. the period when fry are usually stocked. Sodium bicarbonate application did not reduce (P > 0.05) pH in culture ponds. However, ponds that only received organic fertilizer had pH values that were significantly lower than those of the other treatments on 75% of the experiment days. Chlorophyll-a, total ammonia nitrogen, and unionized ammonia nitrogen concentrations were also significantly lower in organic-only fertilized ponds than in the other two treatments on most days and were well below sunshine bass fry tolerance limits. For most water chemistry variables tested, use of sodium bicarbonate did not improve water quality. Although total nutrient input was lowest in the organic-only fertilized ponds, the densities of phytoplankton, rotifers, copepod nauplii, copepod adults, and cladocerans were not significantly different from those of other treatments. These results indicate that sodium bicarbonate does not ameliorate high pH; however, use of only organic fertilizer does reduce pH without reducing zooplankton standing crops.

Methods with strong qualitative thoroughness for species detection often lack the intensity necessary to monitor vegetation change. Four sampling methods (systematic plot, stratified-random plot, modified Whittaker, and timed meander) in hemlock and red oak forests in the Delaware Water Gap National Recreation Area were compared for their ability to detect and monitor understory exotic invasive plant species. The timed-meander method best detected exotic invasive plants and documented richness. The stratified-random method was similar to the timed-meander method in terms of detection of exotic invasives and defining richness, but also provided estimates of species abundances and diversity. An initial combination of the timed-meander and stratified-random sampling designs followed by monitoring with the stratified-random method is suggested as a standard approach.

TI AgBase: a unified resource for functional analysis in agriculture SO NUCLEIC ACIDS RESEARCH LA English DT Article ID GENE ONTOLOGY; MASS-SPECTROMETRY; GENOME ANNOTATION; CHICKEN GENOME; DRAFT SEQUENCE; EXPRESSION; PROTEOME; UNIPROT; MAP AB Analysis of functional genomics (transcriptomics and proteomics) datasets is hindered in agricultural species because agricultural genome sequences have relatively poor structural and functional annotation. To facilitate systems biology in these species we have established the curated, web-accessible, public resource 'AgBase' (www.agbase.msstate.edu). We have improved the structural annotation of agriculturally important genomes by experimentally confirming the in vivo expression of electronically predicted proteins and by proteogenomic mapping. Proteogenomic data are available from the AgBase proteogenomics link. We contribute Gene Ontology (GO) annotations and we provide a two tier system of GO annotations for users. The 'GO Consortium' gene association file contains the most rigorous GO annotations based solely on experimental data. The 'Community' gene association file contains GO annotations based on expert community knowledge (annotations based directly from author statements and submitted annotations from the community) and annotations for predicted proteins. We have developed two tools for proteomics analysis and these are freely available on request. A suite of tools for analyzing functional genomics datasets using the GO is available online at the AgBase site. We encourage and publicly acknowledge GO annotations from researchers and provide an online mechanism for agricultural researchers to submit requests for GO annotations.

We monitored manure and soil P over 14 to 17 months in field experiments in Texas and Pennsylvania, USA following dairy and poultry manure surface application. Manure was applied to porous fabric that enabled discrete sampling of both manure and underlying soil. Manure mass consistently decreased while manure total P was essentially constant through time. Manure water extractable P decreased rapidly for the first two months, likely due to rainfall leaching, but then maintained stable concentrations thereafter, with other forms of manure P gradually transformed to water extractable forms. Soil P from the upper 2 cm rapidly increased after manure application in association with manure leaching by rain. After 2 to 3 months, soil P peaked and either remained constant or gradually declined. Similar trends occurred at 2-5 and 5-10 cm, but with lesser magnitudes. At 10-15 cm, soil P changed little over time. In Pennsylvania, naturally occurring runoff from 0.7-m x 1.3-m plots without and without manure was also monitored. Runoff dissolved P concentrations were greatest for the first event after manure application and decreased steadily through time, but remained greater than P concentrations from control plots, and were always well related to manure water extractable P. This study reveals that management practices for water quality protection must consider the potential for manure P transformations to contribute dissolved P to runoff long after manure is applied.

TI Body Mass Index, percent body fat, and regional body fat distribution in relation to leptin concentrations in healthy, non-smoking postmenopausal women in a feeding study SO NUTRITION JOURNAL LA English DT Article ID BREAST-CANCER CELLS; HORMONE REPLACEMENT THERAPY; PLASMA LEPTIN; ALCOHOL-CONSUMPTION; NORMAL-WEIGHT; GROWTH-FACTOR; ADIPOSITY; INSULIN; OVERWEIGHT; EXERCISE AB Background: The relationship between BMI and leptin has been studied extensively in the past, but previous reports in postmenopausal women have not been conducted under carefully controlled dietary conditions of weight maintenance using precise measures of body fat distribution. The aim of the present study was to examine the association between serum leptin concentration and adiposity as estimated by BMI and dual energy x-ray absorptiometry (DEXA) measures (percent body fat, central and peripheral fat, and lean mass) in postmenopausal women. Methods: This study was conducted as a cross-sectional analysis within the control segment of a randomized, crossover trial in which postmenopausal women (n = 51) consumed 0 (control), 15 (one drink), and 30 (two drinks) g alcohol (ethanol)/d for 8 weeks as part of a controlled diet. BMIs were determined and DEXA scans were administered to the women during the 0 g alcohol treatment, and a blood sample was collected at baseline and week 8 of each study period for leptin analysis. Results and discussion: In multivariate analysis, women who were overweight (BMI > 25 to <= 30 kg/m(2)) had a 2-fold increase, and obese women (BMI > 30 kg/m(2)) had more than a 3-fold increase in serum leptin concentrations compared to normal weight (BMI <= 25 kg/m(2)) women. When the models for the different measures of adiposity were assessed by multiple R-2, models which included percent body fat explained the highest proportion (approximately 80%) of the serum leptin variance. Conclusion: Under carefully controlled dietary conditions, we confirm that higher levels of adiposity were associated with higher concentrations of serum leptin. It appears that percent body fat in postmenopausal women may be the best adiposity-related predictor of serum leptin.

It is difficult to assess whether individuals are following a dietary pattern recommended for cardiovascular disease prevention in large population based studies. Therefore, the association between phylloquinone (vitamin K-1) intake, derived mainly from green vegetables, and risk of cardiovascular diseases [total and fatal coronary heart disease (CHD), non-fatal myocardial infarction, total and ischemic stroke] was prospectively assessed. Methods and results: The study was conducted in 40,087 men who participated in the Health Professionals' Follow-up Study during 1986-2000. There were 1857 CHID events and 617 strokes. After adjustment for lifestyle factors, the relative risks of total CHD events in increasing quintile categories of phylloquinone intake were 1 (reference), 0.84, 0.87, 0.82 and 0.84, respectively (P for trend 0.05). However, the risk of CHD events and strokes did not remain significantly associated with phylloquinone intake after adjustment for lifestyle and other dietary factors. Conclusion: These results suggest that although not an independent risk factor, high phylloquinone intake may be a marker of dietary patterns associated with lower CHD risk and useful when used within that context.

However, the extent to which exercise influences energy regulation and facilitates a reduction in body fat is less clear. This review summarizes published studies on the effects of different amounts of exercise on body fatness, energy intake, and food preferences in humans. The results show consistent effects of exercise on body fatness in the absence of prescribed dietary change, with a progressive loss of body fat associated with higher exercise energy expenditures in both men and women. In part, these effects appear to be mediated by a spontaneous reduction in hunger associated with participation in exercise. Insufficient data are available on whether there are changes in food preferences and taste perception that influence energy balance through macro-nutrient selection, so further studies in this area are needed.

Assessment of body weight is limited by the confounding effect of fluid status especially in the first few days of life, and measurements of linear growth are relatively imprecise and slow to respond to nutritional changes. Growth assessment is hampered by the lack of an adequate reference standard. Comparisons to historical cohorts of preterm babies are inadequate. As most very low birth weight infants leave hospital below the 10th centile, use of these charts as 'standards' almost guarantees that preterm infants will have poor growth. Growth centiles based on data from newborn preterm infants have certain advantages. However, this is hardly normative data as preterm birth is always an abnormal event. Methods of assessing body composition are largely limited to the research setting, and it remains unclear whether the optimum composition of postnatal growth is one that mimics fetal growth or postnatal growth of the term infant. Biochemical nutritional assessments are of limited utility except in the highest-risk preterm infants, when nutritional inadequacy is likely (severe fluid restriction) or where intake is difficult to assess (use of human milk).

Direct plating using agars is an effective tool for laboratory tests and analyses of microorganisms. The morphology (size, growth pattern, color, etc.) of colonies grown on agar plates has been widely used to tentatively differentiate organisms. However, it is sometimes difficult to differentiate target organisms like Campylobacters from other contaminants grown together on the same agar plates. A hyperspectral imaging system operating at the visible and near infrared (VNIR) spectral region from 400 run to 900 nm was set up to measure spectral signatures of 17 different Campylobacter and non-Campylobacter subspecies. Protocols for culturing, imaging samples and for calibrating measured data were developed. The VNIR spectral library of all 17 organisms commonly encountered in poultry was established from calibrated hyperspectral images. A classification algorithm was developed to locate and identify Campylobacters, non-Campylobacter contaminants, and background agars with 99.29% accuracy. This research has a potential to be expanded to detect other pathogens grown on agar media.

The mycotoxin, deoxynivalenol (also known as DON or vomitoxin) is often produced by this mold, which, upon ingestion, causes health problems to not only livestock (especially non-ruminants), but to humans as well. In the United States, the FDA has established advisory levels for DON in food and feeds, a practice that is likewise conducted by most countries of the world. Our previous research has shown that commercial high-speed optical sorters are on average 50 percent efficient at the removal of mold-damaged kernels; however, under more careful control in the laboratory, this efficiency can rise to 95 percent or better. Ongoing research is examining the potential to achieve the higher efficiencies at conditions that are more akin to those of commercial processing. For example, multispectral information is collected on single kernels in freefall at the sub-millisecond level. Knowledge gained from this research will provide design criteria for improvement of high-speed optical sorters for reduction of DON in raw cereals commodities, as well as in finished food products.

A 385 rim light emitting diode (LED) is used as the excitation source and a photomultiplier tube as the light detector. OTC is extracted from honey and cleaned up by solid phase extraction (SPE) using Strata X-WC weak cation exchange cartridges. To the eluate Eu(III) is added to form a Eu-TC chelate at pH 8.5. Efficient intrachelate energy transfer allows sensitive OTC detection at lambda(ex)=385 nm and lambda(em)=610 rim. After a 25-mu s time delay, the ESL signal is integrated over a 25-1000 mu s interval. The signal intensity reveals a linear relationship (R-2=0.972) to OTC concentrations in the 10-200 ng/g range. The limit-of-detection is 6.7 ng/g with an average 5.8% relative standard deviation. The background signal corresponds to similar to 10 ppb. This instrumentation and method combination enables field analysis that is especially useful for beekeeping industry.

Spatially-resolved hyperspectral images were acquired from 600 'Golden Delicious' apples, and values for mu(a) and mu(s)' were determined using an inverse algorithm to fit the diffusion theory model to the spectral scattering profiles over 500-1000 nm. There were two predominant peaks in the absorption spectra around 675 nm and 970 nm due to the presence of chlorophyll and water in the fruit, respectively. Spectra of mu(s)' decreased monotonically with the increasing wavelength. Both mu(a) and mu(s)' were correlated with fruit firmness, with the correlation coefficient (r) of 0.82 and 0.80, respectively. Values of mu(a) were also correlated with the SSC with r=0.70. The combined data of mu(a) and mu(s)' were able to predict fruit firmness with r=0.88 and the standard error of prediction (SEP) of 5.66 N, and SSC with r=0.82 and SEP=0.75%. This research demonstrated the potential of using spectral absorption and scattering properties to evaluate internal quality attributes of horticultural products.

Using remotely sensed imagery to detect the land use and land coverage is one of the most widely-used, cost-effective approaches. However, there is little published research on citrus grove change detection using remotely sensed multi-spectral imagery, especially for those acquired by heterogeneous sensors. The purpose of this paper is to investigate the effectiveness of the citrus change detection based on the histogram matching normalization to the heterogeneously sensed imagery. In this paper, it is found that different reference image and band selection will result in different normalization performance. Based on this finding, a concept of finding optimal reference image and best spectral band for normalization in terms of the minimum Manhattan distance measure is presented. In this paper, the comparison of change detection results of unnormalized and histogram matching normalized images is presented. The experimental results show that histogram matching normalization significantly improves the image differencing based change detection results of the heterogeneously sensed citrus images, and the optimal reference image and band found with proposed optimization algorithm gives the best change detection results.

The intensity of luminescence generated by the oxidation of luminol-liked compounds was used to represent the concentration of toxins produced. The time-course of SLT production by E. coli O157:H7 under different conditions was investigated. In pure culture, optimal generation of SLT showed a significant delay than the steady state of cell growth. In mixed cultures of SLT producing E. coli O157:H7 and non-SLT producing E. coli K-12 strain, the production of toxins was substantially decreased. However, the growth of E. coli O157:117 was not affected by the presence of K-12 strain. This decrease in SLT production was also observed in radiation-sterile ground beef In regular ground beef that might contain numerous other bacteria, the growth of E. coli O157:H7 in EC media was not significantly affected but the lowered production of SLT was observed. The results showed that mechanism of inducing SLT production was complex with both the growth time and growth environment could influence SLT production. The addition of homo-serine lactone to the growth media enhanced the production of SLT. Thus, possibly cell-cell communication may have a role in SLT production by E. coli O157:H7.

Much of this growth was made possible by rapidly increasing consumer interest, which fostered new market opportunities for organic food producers, retailers, and distributors. Market distribution networks have changed character as organic and conventional firms have joined forces, catapulting organic foods into mainstream grocery stores within the reach of most consumers. Consumers now buy organic food for health, taste, and social factors, in additional to the traditional environmental reasons. Even as consumers buy organic food for a wider variety of factors, direct sales from farmers to consumers have remained an important component of the organic market as the market has grown.

Linnaeus), particularly where it has not been eradicated. Identifying and understanding the survival of overwintered boll weevils, when cotton is not available, is important in designing mitigation programs and controlling this insect pest, especially in areas where boll weevils are active all year. Many non-malvaceous taxa have been listed as possible overwintering adult food sources. The purpose of this research was to determine if pollen from three non-malvaceous taxa could be used as food sources for overwintering boll weevils in the Lower Rio Grande Valley of Texas, where weevils are active year-round and during cotton-free periods. The taxa are almond [Prunus dulcis (Mill.) D.A. Webb], melon (Cucumis melo C. Linnaeus subsp. melo), and pigweed (Amaranthus sp.), Furthermore, it was intended to determine the retention of these pollen types in the boll weevil gut. More weevils (84%) contained almond pollen when they had additional water than those (30%) that did not have additional water. Almond pollen was found in 100% of the examined weevils after 72 hours, and in 80% after 96 hours. Pigweed and melon pollen were never found after 48 hours. Overall, almond pollen was found in more weevils (96%) than pigweed (40%), or melon (12%). In addition, a greater number of almond pollen grains (539) were found than pigweed (41), or melon (21). This shows that these types of pollen were consumed, and could play a part in the survival of overwintering weevils. However, more research is needed to examine the nutritional value of these, and other, pollen grains for overwintering boll weevil survival, and to determine the length of time weevils can survive feeding on these pollen types.

Several studies were conducted to examine the relationship between egg maturation and deposition with the flowering phenology of its host plant. Female weevils fed different diets of flowers and foliage showed significant differences in ovarian development. Females relied on their stored fat reserves to sustain them through the winter season. Stored fat in newly emerged females was 21% in June or July, declining to 10% by late January the following year. Fat maintenance was sustained throughout the ovipositional period by both flower and foliage feeding. The results show that the biology and life cycle of this weevil was closely tied to the production of flowers by gorse. Oviposition was synchronized with anthesis and flower feeding in March (early spring). Larval development occurred in late March through mid-May and adult emergence began in early M ay. Larval consumption of seeds was the primary means of feeding damage. When present, larval feeding reduced seed number per pod between 64% and 87%. Infestation of seedpods by weevils varied from 4% (late March) to 71% (early June) and translated to a population-level estimate of seed destruction of 51%.

Sagebrush steppe is a common natural habitat adjacent to apple and pear orchards in that part of the state. Many predatory arthropod species found on the native plants also occur in adjacent orchards; some of these species were particularly abundant on the plants when they were flowering. Other species found on the native plants rarely occur in adjacent orchards. Orius tristicolor (White, 1879) was the most abundant of the natural enemies that also occur in orchards. Other predatory Hemiptera also found in adjacent orchards included Deraeocoris brevis (Uhler, 1904), Nabis alternatus Parshley, 1922, and Geocoris spp. Coccinellidae, Chrysopidae, and Hemerobiidae were not common on the native plants, but one or more species in each family that commonly occur in orchards were collected. Spiders found on the native plants that also occur in orchards included Misumenops lepidus (Thorell, 1877), Xysticus cunctator Thorell, 1877, Sassacus papenhoei Peckham & Peckham, 1895, Phidippus spp., Oxyopes scalaris Hentz, 1845, and Meioneta fillmorana (Chamberlin, 1919). Parasitoids, almost all of which were Hymenoptera, were collected on,all plants, but species of known importance in orchard biocontrol were not found.

Our objective was to determine the relative effects of biotic vs. abiotic factors on soil. N transformations. During the 1999 and 2000 growing seasons we transplanted soil cores from each of the five gradient plots to all other gradient plots for their 28-day in situ incubation. N mineralization and nitrification rates in soils from the northern hardwood (NH) site were significantly increased when soils were transplanted to warmer sites. N mineralization rates also increased in transplanted soil from the dry mixed-oak/pine site to a wetter site. Multiple regression analysis of N mineralization from all five sites found that biotic (total soil N and C:N ratios) and climatic factors (moisture and temperature) regulate N mineralization. Regression analyses of individual, sites showed that N mineralization rates responded to variation in temperature and moisture at only the high elevation northern hardwood site and moisture alone on the dry warm mixed-oak/ pine site. N mineralization was unrelated to temperature or moisture at any of the other sites. Results indicate that soil. properties plus climatic conditions affect soil N transformations along the environmental gradient at Coweeta. Environmental, controls were significant only at the extreme sites; i.e., at the wettest and warmest sites and soils with highest and lowest C and N contents. The high degree of temperature sensitivity for the northern hardwood soils indicates potentially large responses to climatic change at these sites. Published by Elsevier GmbH.

Introduction of blight-resistant American chestnut hybrids wilt probably start in the next decade after many years of tree breeding. What were the historic effects of chestnut on forest soils, and what changes may follow reintroduction of hybrid chestnuts? A site in southern Wisconsin provided an opportunity to examine the effect of chestnut trees on soil properties. At this site, 600 km northwest of chestnut's historic distribution, naturalized chestnuts have spread throughout an intact mixed-species forest from nine planted trees. The site contains soil developed on a silty loess-mantled ridge that abuts sandier hillslopes, allowing the effects of individual, chestnuts to be examined on two soil types. I sampled and analyzed forest floor and mineral soils beneath canopies of individual American chestnuts and the surrounding mixed-species deciduous forest on fine-silt and sandy-loam soil types. On sandy loam soils, total soil carbon (C) and nitrogen (N), inorganic N and net mineralization and nitrification rates were 10-17% higher beneath chestnut canopies compared to soils beneath mixed-species deciduous forest. The pool of total soil N beneath chestnut canopies was positively related to the silt content of the sandy loam soils. In contrast, there were no differences between properties of chestnut canopy and mixed-species deciduous forest soils on the fine silt texture class. On sandy loam soil conditions common throughout the pre-blight distribution of American chestnut, soil. biogeochemical. processes differ beneath individual chestnut trees relative to a diverse mixture of deciduous species. These findings suggest that widespread chestnut reintroduction has the potential to alter both stand- and watershed-scale processes. Published by Elsevier GmbH.

Our objectives were to quantify differences in forest floor CO2 flux among age classes, and determine the relative importance of abiotic and biotic driving variables. Forest floor CO2 flux was measured using an openflow infrared gas analyzer measurement system for 24h periods and samples were taken every 2 months over a 2-year period. Litter/soil interface, soil temperature (5 cm depth), soil moisture (%), forest floor moisture (%), forest floor mass, fine root (<= 2 mm) mass, coarse root mass (> 2 mm), forest floor C and N (%), fine root C and N, coarse root C and N, and soil N and C were co-measured during each sample period. Results showed significant nonlinear relationships (r(2) = 0.68 to 0.81) between Litter/soil interface temperature and forest floor CO2 flux for all, three forest age classes, but no differences in temperature response parameters. These results indicated no differences in forest floor CO2 flux among age classes. Considerable temporal variation in abiotic and biotic variables was observed within and among forests. Biotic variables correlated with forest floor CO2 flux included indices of litter and root quality. Differences in biotic variables correlated with forest floor CO2 flux among forests may have been related to shifts in the relative importance of heterotrophic and autotrophic respiration components to overall forest floor CO2 flux.

This peptide occurs with a single isoform in all insects studied so far, with the exception of the Coleoptera in which no corazonin form could be detected. Very few modifications of [Arg(7)]-corazonin, originally isolated from cockroaches, are known, namely [His(7)]-corazonin which is expressed in certain locusts and the stick insect Carausius morosus, and [Thr(4), His(7)]-corazonin recently described: from the honey bee Apis mellifera. In this study, we performed a comprehensive screening for corazonin in the different insect groups after detecting of a fourth isoform in a crane fly, Tipula sp. ([Gln(10)]-corazonin). [Arg(7)]-corazonin is distributed in most major lineages of insects, and is thus the ancient form which was present at the time the phylum Insecta evolved. The replacement of Arg with His at position 7 from the N-terminus occurred several times in the evolution of insects. The third isoform, [Thr(4), His(7)]-corazonin, seems to be restricted to bees (Apidae); whereas wasps (Vespidae) and a bumble bee (Apidae) express other corazonins, specifically [His(7)]-corazonin and [Tyr(3), Gln(7), Gln(10)]-corazonin, respectively. A novel corazonin form, [His(4), Gln(7)]-corazonin, was also detected in all South African members of the newly described insect order Mantophasmatodea. The [His(4), Gln(7)]-corazonin separates these species from the Namibian Mantophasmatodea which express [Arg(7)]corazonin and can be used as a distinct character to distinguish these morphologically similar insects.

The C-terminal hexapeptide proved to be the active core, the minimum sequence required to retain significant diuretic activity. However, full activity required the C-terminal heptapeptide, which was equipotent with the most active of the native housefly CAP2b peptides. Replacement of Arg(7) and Val(8) with Ala led to inactivity and a large 70-fold drop in potency, respectively, indicating that these were critical residues. The Leu(2) was semicritical, where a six-fold loss in potency was observed. Conversely, the replacement of all other residues with Ala led to much smaller effects on potency and these positions were considered to be noncritical. This structure- activity relationship data can aid in the design of mimetic agonist/antagonist analogs of this diuretic peptide family with enhanced biostability and bioavailability, as tools for arthropod endocrinologists and as potential pest management agents capable of disrupting the water balance in pest flies.

The C-terminal FXGXRa-motif constitutes the consensus active core region of invertebrate tachykinins. In Drosophila, two putative G protein-coupled tachykinin receptors have been cloned: DTKR and NKD. This study focuses on the functional characterization of DTKR, the Drosophila ortholog of the stable fly's tachykinin receptor (STKR). Tachykinins containing an alanine residue instead of the highly conserved glycine (FXAXRa) display partial agonism on STKR-mediated Ca2+-responses, but not on cAMP-responses. STKR therefore seems to differentiate between a number of tachykinins. Gly- and Ala-containing tachykinins are both encoded in the Drosophila tachykinin precursor, thus raising the question of whether DTKR can also distinguish between these two tachykinin types. DTKR was activated by all Drosophila tachykinins and inhibited by tachykinin antagonists. Ala-containing analogs did not produce the remarkable activation behavior previously observed with STKR, suggesting different mechanisms of discerning ligands and/or activating effector pathways for STKR and DTKR.

A C-terminal aldehyde insect kinin analog, Fmoc-RFFPWG-H (R-LK-CHO), demonstrates stimulation of Malpighian tubule fluid secretion in crickets, but shows inhibition of both in vitro and in vivo diuresis in the housefly. R-LK-CHO reduced the total amount of urine voided over 3 h from flies injected with 1 mu L of distilled water by almost 50%. The analog not only inhibits stimulation of housefly fluid secretion by the native kinin Musdo-K, but also by thapsigargin, a SERCA inhibitor, and by ionomycin, a calcium ionophore. The activity of R-LK-CHO is selective, however, as related C-terminal aldehyde analogs do not demonstrate an inhibitory response on housefly fluid secretion. The selective inhibitory activity of R-LK-CHO on housefly tubules represents an important lead in the development of environmentally friendly insect management agents based on the insect kinins.

TI Enhanced degradation of atrazine under field conditions correlates with a loss of weed control in the glasshouse SO PEST MANAGEMENT SCIENCE LA English DT Article DE weed control; pesticide; accelerated degradation ID PSEUDOMONAS SP; STRAIN ADP; ACCELERATED DEGRADATION; MINERALIZATION; SOILS; BIODEGRADATION; MANAGEMENT; ENZYMES; GENE AB Enhanced degradation of atrazine has been reported in the literature, indicating the potential for reduced residual weed control with this herbicide. Experiments were conducted to determine the field dissipation of atrazine in three cropping systems: continuous Zea mays L. (CC) receiving atrazine applications each year, Gossypium hirsutum L.-Z. mays rotation (CCR) receiving applications of atrazine once every 2 years and a no atrazine history soil (NAH). Subsequent laboratory and greenhouse experiments were conducted with soil collected from these cropping systems to determine atrazine degradation, mineralization and residual weed control. Field dissipation of atrazine followed first-order kinetics, and calculated half-life values for atrazine combined over 2003 and 2005 increased in the order of CC (9 d) = CCR (10 d) < NAH (17 d). Greenhouse studies confirmed that the persistence of atrazine was approximately twofold greater in NAH soil than in CC or CCR soil. Biometer flask mineralization studies suggested that enhanced degradation of atrazine was due to rapid catabolism of the s-triazine ring. Glasshouse efficacy studies revealed a loss of residual weed control in CC and CCR soil compared with NAH soil. These data indicate that, under typical Mississippi Delta field conditions and agronomic practices, the persistence of atrazine may be reduced by at least 50% if the herbicide is applied more than once every 24 months. Glasshouse studies suggest that under these conditions a loss of residual weed control is possible.

Proteinase inhibitors are potential candidates for enhancing Bt toxicity against lepidopteran pests and for expanding the spectrum of control for other insects. Interactions of Bt toxin from Bacillus thuringiensis and protemase inhibitors were investigated by monitoring growth, development, and gut protemase activities of the bollworm, Helicoverpa zea. Several proteinase inhibitors were combined with Bt protoxin CrylAc in artificial diet and fed to newly molted 3rd-instar bollworm larvae to determine effects on larval body weight and length, pupation progress, and mortality rate. Major midgut protemase activities, including caseinase, tryptic., and chymotrypsin activities, were examined after treatment. A concentration of Bt at a level causing minimal mortality (< 10%), was mixed with the following protemase inhibitors: benzamidine, phenylmethylsulfonyl fluoride (PMSF), and N-alpha-tosyl-L-lysine chloromethyl ketone (TLCK). When compared with controls, the synergistic effect of Bt toxin and proteinase inhibitors caused significant decreases in mean larval weight and length over time. Midgut samples tested against the substrates azocasein, alpha-benzoyl-DL-arginine-p-nitroanilide (BApNA), and N-succinyl-alanine-alanine-proline-phenylalanine-p-nitroanilide (SAAPFpNA) showed significant decreases in the protease activity of larvae fed Bt plus inhibitor versus control. Interaction of Bt and protemase inhibitors significantly retarded larval growth and resulted in developmental delay and up to 20% mortality. (c) 2006 Elsevier Inc. All rights reserved.

Continuous and dominant use of chemical sprays has facilitated resistance development in the tarnished plant bug. A natural population in Mississippi with resistance to malathion was studied to examine whether and how glutathione S-transferases (GST) played an important role in the resistance. Bioassays were first conducted to examine synergism of two GST inhibitors. Both ethacrynic acid (EA) and diethyl maleate (DM) effectively abolished resistance and increased malathion toxicity against two resistant strains by more than 2- and 3-fold, whereas incorporation of GST inhibitors did not significantly increase malathion toxicity against a susceptible strain. GST activities were compared in vitro between malathion susceptible and resistant strains by using 1-chloro-2,4-dinitrobenzene as a GST substrate. The resistant strain had significantly higher (1.5-fold) GST activity than the susceptible strain. Up to 99%, 75%, and 85% of the GST activities were inhibited by EA, sulfobromophthalein (SBT), and DM, respectively. The GST activities tended to increase from May to October by 1.76-fold. All three inhibitors significantly suppressed the GST activity to a constant low level over the season. Further examination of GST cDNA indicated that in the coding region only one nucleotide variation was revealed between the susceptible and resistant strain. This variation did not cause a protein sequence change, and an identical amino acid sequence was predicted for both strains. Multiple sequence alignment and phylogenetic analysis showed that the 216-residue GST from the tarnished plant bug was highly similar (up to 68% of amino acid sequence identity) to the GSTs from other insects, which conferred organophosphate resistance. GST gene expression levels were examined using real-time PCR, and the results indicated that GST gene transcripts were elevated in the resistant strain by 1.3-fold. Published by Elsevier Inc.

This process is capable of removing all or a substantial amount of asphaltenes from feedstocks that are destined for further processing and thus applied as the first step of refining. Maltenes and asphaltenes obtained from vacuum residues of Heera (HVR) and Jodhpur (JVR) Indian crude oils using n-hexane, n-heptane, and soluble and insoluble fractions obtained using ethyl acetate, were characterized for elemental analysis, molecular weight, conradson carbon residue (CCR), specific gravity, and pour points. The resulting degree of removal of asphaltenes ranged from 10-28 wt% of the HVR and 25-50 wt% of the JVR. The increasing trend of the American Petroleum Institute (API) gravity and the decreasing trend of CCR and pour point are observed with the increase in removal of asphaltenes.

The effect of various solvents on average molecular structure of asphaltenes and insolubles was studied using nuclear magnetic resonance spectroscopy (NMR), Fourier transform infrared spectroscopy (FTIR), and size exclusion chromatography (SEC). The asphaltenes and insolubles of Jodhpur VR have higher amounts of high molecular weight species with a high concentration of condensed and substituted aromatic rings, branched and/or short alkyl side chains, oxygen and nitrogen functionalities, compared to that of Heera VR. Ethyl acetate insolubles comprise a higher number of substituted aromatic structures, branched aliphatic structures, complex average unit structures, nitrogen and oxygen functionalities, and high molecular weight (MW) species as compared to hexane and heptane asphaltenes. Heptane insolubles consist of more naphthenic rings condensed with aromatic rings than C6A and EAI. C1 ARS, NCAUR, USDA, Peoria, IL 61604 USA.

Chl contents and composition were examined among 833 soybean (Glycine max L. Merr.) accessions and related to SPAD meter readings and leaf N content. In the initial year of the study (2002), the relationship between leaf Chl and leaf N contents (r(2) = 0.043) was not sufficiently close for Chl to be useful as a predictive tool for leaf N content. Therefore, leaf N content was not determined in 2004 but samples were again collected for determination of Chl content and composition. In 2002, the soybean accessions separated into two distinct groups according to leaf Chl a/b ratios, with the majority of a mean ratio of 3.79. However, approximately 7 % (60) of the genotypes could be readily assigned to a group with a mean Chl a/b ratio of 2.67. Chl a/b analyses in 2004 confirmed the results obtained in 2002 and of 202 genotypes, all but 6 fell into the same group as in 2002. C1 USDA ARS, Crop Genet & Prod Res Unit, Stoneville, MS 38776 USA.

Recombinant Arabidopsis thalianaPDH(E1) was used to calibrate the ELISA. Antibodies against a synthetic phosphopeptide corresponding to phosphorylation site one of E1 alpha were used in an ELISA to quantify phospho-PDC (P-PDC). For calibration of the second ELISA, recombinant E1 was phosphorylated in vitro with recombinant A. thaliana E1-kinase. The two ELISA were used to quantify mitochondrial total- and P-PDC in clarified homogenates from Nicotiana tabacum BY-2 suspension cells. The level of mtPDC remained constant throughout the 7-day growth cycle at 25.1 g(-1) FW. During the lag (days 0-2) and stationary ( day 7) stages of the growth cycle, the mtPDC was completely phosphorylated (inactive), whereas during the log-growth stage it was completely dephosphorylated (active). Exposure of 3- or 7-day posttransfer suspension cells to osmotic stress significantly decreased proportion of P-PDC. A series of pharmacological studies were undertaken to gain insight into the signal transduction pathways coupling osmotic stress perception with control of mitochondrial respiration. Results from these studies indicate a signal transduction pathway linking stress perception to control of mitochondrial respiration that includes protein kinases and phosphoprotein phosphatases.

Plants showing mosaic symptoms declined rapidly and, in many cases, died after several years. Double-stranded RNA extraction from symptomatic black raspberry revealed the presence of two high molecular weight bands which were cloned and sequenced. Sequence analysis disclosed the presence of a novel virus that was tentatively named Black raspberry decline-associated virus (BRDaV). The complete sequences of the two genomic RNAs, excluding the 3' polyadenosine tails, were 7,581 and 6,364 nucleotides, respectively. The genome organization was identical to that of Strawberry mottle virus, a member of the genus Sadwavirus. The C terminus of the RNA I polyprotein is unique within the genus Sadwavirus, with homology to AlkB-like domains, suggesting a role in repair of alkylation damage. A reverse-transcriptase polymerase chain reaction test was designed for the detection of BRDaV from Rubus tissue, and tests revealed that BRDaV was associated consistently with the observed decline symptoms. While this publication was under review, it came to our attention that scientists at the Scottish Crop Research Institute had molecular data on Black raspberry necrosis virus (BRNV), a virus that shared many biological properties with BRDaV. After exchange of data, we concluded that BRDaV is a strain of BRNV, a previously described yet unsequenced virus. The North American strain was vectored nonpersistently by the large raspberry aphid and the green peach aphid. Phylogenetic analysis indicates that BRNV belongs to the genus Sadwavirus.

Poor quality seeds, however, were highly susceptible to both phases of seedling disease and required seed treatment in order to survive. Preemergence damping-off incited by Pythium spp. and Rhizopus oryzae could be controlled by seed treatment with biocontrol preparations of a number of Trichoderma spp., but these treatments were much less effective in controlling postemergence disease incited by Rhizoctonia solani. Postemergence seedling disease can be controlled by fungicides, but they were much less effective in controlling the pre-emergence phase of the disease. Combination seed treatments of poor quality cotton seeds with fungicides and Trichoderma spp. preparations, followed by planting in pathogen-infested soil, indicated that this technique will control both phases of seedling disease. Seed treatment with either the fungicides or the biocontrol agents alone did not achieve this goal. The optimum combination treatment for disease control was that of chloroneb plus Trichoderma spp., followed by chloroneb plus metalaxyl (Deltacoat AD) plus T virens strain G-6.

Both herbal teas are used traditionally for medicinal purposes and are rich in polyphenols with rooibos a rare source of the dietary dihydrochalcones, aspalathin and nothofagin. The principal polyphenols in honeybush include the xanthone mangiferin and the Havonones hesperitin and isokuranetin. Despite their divergent phytochemical and nutrient compositions, rooibos and honeybush share potent antioxidant and antimutagenic activities in vitro. Animal model studies indicate both herbal teas possess potent antioxidant, immune-modulating and chemopreventive actions. However, human studies of rooibos are limited and of honeybush are absent. No adverse effects of rooibos or honeybush consumption as tisanes have been reported. Copyright (c) 2006 John Wiley & Sons, Ltd. C1 Tufts Univ, USDA, Human Nutr Res Ctr Aging, Boston, MA 02111 USA.

We probed thin sections of mature cotyledon epidermal transfer cells of Vicia faba with affinity probes and antibodies specific to polysaccharides and glycoproteins, to determine the distribution of these components in their walls. Walls of these transfer cells consist of the pre-existing primary wall, a uniformly deposited wall layer and wall ingrowths which are comprised of two regions; an electron-opaque inner region and an electron-translucent outer region. The primary wall reacted strongly with antibodies against esterified pectin, xyloglucan, the side chains of rhamnogalaturonan-1 and a cellulase-gold affinity probe. The electron-opaque inner region of wall ingrowths displayed a similar labeling pattern to that of the primary wall, showing strong cross-reactivity with all antibodies tested, except those reacting against highly de-esterified pectins. The electron-opaque outer layer of developmentally more mature wall ingrowths reacted strongly with anti-callose monoclonal and polyclonal antibodies, but showed no reaction for pectin or xyloglucan antibodies or the cellulase-gold affinity probe. The plasma membrane-wall interface was labeled strongly with anti-arabinogalactan protein (AGP) antibodies, with some AGP-reactive antibodies also labeling the electron-translucent zone. Nascent wall ingrowths were labeled specifically with AGPs but not anti-callose. A reduction in wall ingrowth density was observed when developing transfer cells were exposed to beta-d-glucosyl Yariv reagent compared with controls. Our results indicate that wall ingrowths of transfer cells are primary wall-like in composition and probably require AGPs for localized deposition.

Some of the best examples of natural microbial defense of plant roots occur in disease suppressive soils. Soil suppressiveness against many different diseases has been described. Take-all is an important root disease of wheat, and soils become suppressive to take-all when wheat or barley is grown continuously in a field following a disease outbreak; this phenomenon is known as take-all decline (TAD). In Washington State, USA and The Netherlands, TAD results from the enrichment during monoculture of populations of 2,4-diacetylphloroglucinol (2,4-DAPG)-producing Pseudomonas fluorescens to a density of 10(5) CFU/g of root, the threshold required to suppress the take-all pathogen, Gaeumannomyces graminis var. tritici. 2,4-DAPG-producing P. fluorescens also are enriched by monoculture of other crops such as pea and flax, and evidence is accumulating that 2,4-DAPG producers contribute to the defense of plant roots in many different agro-ecosystems. At this time, 22 distinct genotypes of 2,4-DAPG producers (designated A-T, PfY and PfZ) have been defined by whole-cell repetitive sequence-based (rep)-PCR analysis, restriction fragment length polymorphism (RFLP) analysis of phID, and phylogenetic analysis of phID, but the number of genotypes is expected to increase. The genotype of an isolate is predictive of its rhizosphere competence on wheat and pea. Multiple genotypes often occur in a single soil and the crop species grown modulates the outcome of the competition among these genotypes in the rhizosphere. 2,4-DAPG producers are highly effective biocontrol agents against a variety of plant diseases and ideally suited for serving as vectors for expressing other biocontrol traits in the rhizosphere.

Arabidopsis accessions are polymorphic for Psi SRK and Psi SCR, but it is unknown if the species harbors structurally different S haplotypes, either representing relics of ancestral functional and structurally heteromorphic S haplotypes or resulting from decay concomitant with or subsequent to the switch to self-fertility. We cloned and sequenced the S haplotype from C24, in which self-fertility is due solely to S locus inactivation, and show that this haplotype was produced by interhaplotypic recombination. The highly divergent organization and sequence of the C24 and Columbia-0 (Col-0) S haplotypes demonstrate that the A. thaliana S locus underwent extensive structural remodeling in conjunction with a relaxation of selective pressures that once preserved the integrity and linkage of coadapted SRK and SCR alleles. Additional evidence for this process was obtained by assaying 70 accessions for the presence of C24- or Col-0-specific sequences. Furthermore, analysis of SRK and SCR polymorphisms in these accessions argues against the occurrence of a selective sweep of a particular allele of SCR, as previously proposed.

We reduced C allocation below ground of loblolly pine trees by: (1) physically girdling trees and (2) physiologically girdling pine trees by chilling the phloem. Chilling reduced cambium temperatures by approximately 18 degrees C. Both methods rapidly reduced soil CO2 efflux, and after approximately 10 days decreased net photosynthesis (P-n), the latter indicating feedback inhibition. Chilling decreased soil-soluble C, indicating that decreased soil CO2 efflux may have been mediated by a decrease in root C exudation that was rapidly respired by microbes. These effects were only observed in late summer/early autumn when above-ground growth was minimal, and not in the spring when above-ground growth was rapid. All of the effects were rapidly reversed when chilling was ceased. In fertilized plots, both chilling and physical girdling methods reduced soil CO2 efflux by approximately 8%. Physical girdling reduced soil CO2 efflux by 26% in non-fertilized plots. This work demonstrates that phloem chilling provides a non-destructive alternative to reducing the movement of recent photosynthate below the point of chilling to estimate C allocation below ground on large trees.

AB Tocopherols, with antioxidant properties, are synthesized by photosynthetic organisms and play important roles in human and animal nutrition. In soybean, gamma-tocopherol, the biosynthetic precursor to alpha-tocopherol, is the predominant form found in the seed, whereas alpha-tocopherol is the most bioactive component. This suggests that the final step of the alpha-tocopherol biosynthetic pathway catalyzed by gamma-tocopherol methyltransferase (gamma-TMT) is limiting in soybean seed. Soybean oil is the major edible vegetable oil consumed, so manipulating the tocopherol biosynthetic pathway in soybean seed to convert tocopherols into more active alpha-tocopherol form could have significant health benefits. In order to increase the soybean seed alpha-tocopherol content, the gamma-TMT gene isolated from Perilla frutescens was overexpressed in soybean using a seed-specific promoter. One transgenic plant was recovered and the progeny was analyzed for two generations. Our results demonstrated that the seed-specific expression of the P. frutescens gamma-TMT gene resulted in a 10.4-fold increase in the alpha-tocopherol content and a 14.9-fold increase in the beta-tocopherol content in T2 seed. Given the relative contributions of different tocopherols to vitamin E activity, the activity in T2 seed was calculated to be 4.8-fold higher than in wild-type seed. In addition, the data obtained on lipid peroxidation indicates that alpha-tocopherol may have a role in preventing oxidative damage to lipid components during seed storage and seed germination. The increase in the alpha-tocopherol content in the soybean seed could have a potential to significantly increase the dietary intake of vitamin E.

We have identified more than 150 sugar beet root ESTs enriched for genes responding to sugar beet root maggot feeding from both moderately resistant, F1016, and susceptible, F1010, genotypes using suppressive subtractive hybridization. The largest number of identified F1016 genes grouped into the defense/stress response (28%) and secondary metabolism (10%) categories with a polyphenol oxidase gene, from F1016, identified most often from the subtractive libraries. The differential expression of the root ESTs was confirmed with RT-PCR. The ESTs were further characterized using macroarray-generated expression profiles from F1016 sugar beet roots following mechanical wounding and treatment of roots with the signaling molecules methyl jasmonate, salicylic acid and ethylene. Of the examined root ESTs, 20, 17 and 11% were regulated by methyl jasmonate, salicylic acid and ethylene, respectively, suggesting these signaling pathways are involved in sugar beet root defense responses to insects. Identification of these sugar beet root ESTs provides knowledge in the field of plant root defense and will lead to the development of novel control strategies for control of the sugar beet root maggot.

To determine which species could function as potential hosts and virus reservoirs, we used aphid transmission and bud or chip grafting to evaluate the susceptibility of commercial, ornamental, and wild Prunus species to isolates of PPV found in Pennsylvania, USA. Following inoculation, test trees were observed for symptoms, analyzed by enzyme-linked immunosorbent assay (ELISA) and polymerase chain reaction (PCR), back-assayed to healthy peach, and followed through at least four cold-induced dormancy (CID) cycles over 4 years. Thirty-one of 33 Prunus species and cultivars were systemically infected following aphid transmission. Systemic infection could not be detected in P. cerasus (sour cherry) and P. x 'Snofozam' (Snow Fountains) despite repeated aphid inoculation attempts. Following grafting of PPV-infected budwood, all 40 species and varieties became infected, although species differed in their susceptibility. Within most species, some individual plants remained PPV negative throughout the study despite repeated inoculations. Infection in some species could be detected only through quantitative reverse transcription (RT)-PCR. Most species displayed clear symptoms, were highly positive by ELISA and RT-PCR, and could be back-inoculated into peach seedlings following CID. Our results indicate that a wide range of native and ornamental Prunus species are susceptible to U.S. isolates of PPV-D. C1 USDA ARS, Foreign Dis Weed Sci Res Unit, Ft Detrick, MD 21702 USA.

The disease has Asian, African, and American forms caused by "Candidatus Liberibacter asiaticus", "Ca. L. africanus", and "Co. L. americanus", respectively, which can be spread efficiently by the psyllid vectors Diaphorina citri and Trioza erytreae and through contaminated plant materials. Infected citrus groves are Usually destroyed or become unproductive in 5 to 8 years. The presumed low concentration and uneven distribution of the pathogens in citrus plants and vector insects make the phloem-limited bacterium difficult to detect consistently. In this study, we compared and validated four conventional polymerase chain reaction (PCR)-based protocols, one loop-mediated isothermal amplification (LAMP) protocol, and three TaqMan real-time PCR protocols. The detection sensitivity of the validated conventional PCR assays reported are improved compared with the original protocols. All of the validated conventional and the newly developed real-time methods were reliable for confirmatory tests for the presence of "Ca. Liberibacter spp." in symptomatic samples. There were no differences in assay specificity among the standard format PCR-based methods evaluated. The TaqMan real-time PCR was 10- to 100-fold more sensitive than conventional PCR and LAMP, showing the potential to become a valuable tool for early detection and identification of "Ca. Liberibacter spp." prior to the appearance of disease symptoms. The methods validated in this study will be very useful for regulatory response, effective management of infected trees, and development of a "Ca. Liberibacter spp."-free nursery system.

When an iron-sulfur cluster is present in its catalytic center, aconitase displays enzymatic activity; when this cluster is lost, it switches to an RNA-binding protein that regulates the translatability or stability of certain transcripts. To investigate the role of aconitase in plants, we assessed its ability to bind mRNA. Recombinant aconitase failed to bind an iron responsive element (IRE) from the human ferritin gene. However, it bound the 5' UTR of the Arabidopsis chloroplastic CuZn superoxide dismutase 2 (CSD2) mRNA, and this binding was specific. Arabidopsis aconitase knockout (KO) plants were found to have significantly less chlorosis after treatment with the superoxide-generating compound, paraquat. This phenotype correlated with delayed induction of the antioxidant gene GST1, suggesting that these KO lines are more tolerant to oxidative stress. Increased levels of CSD2 mRNAs were observed in the KO lines, although the level of CSD2 protein was not affected. Virus-induced gene silencing (VIGS) of aconitase in Nicotiana benthamiana caused a 90% reduction in aconitase activity, stunting, spontaneous necrotic lesions, and increased resistance to paraquat. The silenced plants also had less cell death after transient co-expression of the AvrPto and Pto proteins or the pro-apoptotic protein Bax. Following inoculation with Pseudomonas syringae pv. tabaci carrying avrPto, aconitase-silenced N. benthamiana plants expressing the Pto transgene displayed a delayed hypersensitive response (HR) and supported higher levels of bacterial growth. Disease-associated cell death in N. benthamiana inoculated with P. s. pv. tabaci was also reduced. Taken together, these results suggest that aconitase plays a role in mediating oxidative stress and regulating cell death. C1 Cornell Univ, Boyce Thompson Inst Plant Res, Ithaca, NY 14853 USA.

TI Evaluation of source leaf responses to water-deficit stresses in cotton using a novel stress bioassay SO PLANT PHYSIOLOGY LA English DT Article ID BIOCHEMICAL RESPONSES; ABIOTIC STRESS; UPLAND COTTON; SUGAR-BEET; PLANTS; TEMPERATURE; GROWTH; CARBON; ACCUMULATION; RESPIRATION AB Water-deficit stresses preferentially reduce shoot growth, thereby disrupting the flow of carbohydrates from source leaves to the developing sinks. Here, we use a novel stress bioassay to dissect responses of field and greenhouse-grown cotton (Gossypium hirsutum) source leaves to water-deficit stresses. Fifth main stem leaf samples were harvested at sunrise and subjected to a prolonged elevated respiratory demand in the dark. Sucrose levels are lower in nonstressed cotton at sunrise compared to water-deficit stressed cotton, potentially predisposing the nonstressed tissue to succumb more rapidly. Tissue death was determined initially using the cell viability stain 2,3,5-triphenyltetrazolium chloride, but was determined in subsequent experiments by monitoring the decline in chlorophyll fluorescence yield. Fluorescence yield measurements were obtained within minutes of harvesting and individual samples were monitored over the time course of the treatment. Analyses of the time course and magnitude of chlorophyll fluorescence yield decline in samples from irrigated and dryland plots permitted the detection of stress responses within 24 h of the cessation of irrigation. The rate of fluorescence yield decline during the elevated respiratory demand treatment slowed as the water-deficit stress increased. Upon irrigation, the source leaves of the water-stressed plants recovered to prestress values within 4 d. Well-watered cotton overexpressing heat shock protein 101 had identical rates of fluorescence yield decline as nontransgenic cotton. These results suggest that the delayed decline in fluorescence yield of water-stressed tissue exposed to prolonged elevated respiratory demand can be used as a sensitive indicator of water-deficit stress responses.

The effects of light and temperature on K-leaf are described. Under dark conditions, K-leaf was low, but increased by 400% upon exposure to light. In contrast to dark conditions, K-leaf values of light-exposed leaves responded to temperature and 0.1 mM cycloheximide treatments. Furthermore, K-leaf was not related to stomatal aperture. Data of real-time reverse transcription-polymerase chain reaction showed that K-leaf dynamics were tightly correlated with the transcript abundance of two walnut aquaporins (JrPIP2,1 and JrPIP2,2). Low K-leaf in the dark was associated with down-regulation, whereas high K-leaf in the light was associated with up-regulation of JrPIP2. Light responses of K-leaf and aquaporin transcripts were reversible and inhibited by cycloheximide, indicating the importance of de novo protein biosynthesis inthisprocess. Our results indicate that walnut leaves can rapidly change their hydraulic conductance and suggest that these changes can be explained by regulation of plasma membrane aquaporins. Model simulation suggests that variable leaf hydraulic conductance in walnut might enhance leaf gas exchanges while buffering leaf water status in response to ambient light fluctuations.

TI Decreases in stomatal conductance of soybean under open-air elevation of [CO2] are closely coupled with decreases in ecosystem evapotranspiration SO PLANT PHYSIOLOGY LA English DT Article ID CARBON-DIOXIDE ENRICHMENT; DOUBLED ATMOSPHERIC CO2; LEAF GAS-EXCHANGE; ENERGY-BALANCE; WATER-USE; CANOPY PHOTOSYNTHESIS; GLYCINE-MAX; FACE; NITROGEN; WHEAT AB Stomatal responses to atmospheric change have been well documented through a range of laboratory- and field-based experiments. Increases in atmospheric concentration of CO2 ([CO2]) have been shown to decrease stomatal conductance (g(s)) for a wide range of species under numerous conditions. Less well understood, however, is the extent to which leaf-level responses translate to changes in ecosystem evapotranspiration (ET). Since many changes at the soil, plant, and canopy microclimate levels may feed back on ET, it is not certain that a decrease in g(s) will decrease ET in rain-fed crops. To examine the scaling of the effect of elevated [CO2] on g(s) at the leaf to ecosystem ET, soybean (Glycine max) was grown in field conditions under control (approximately 375 mu mol CO2 mol(-1) air) and elevated [CO2] (approximately 550 mu mol mol(-1)) using free air CO2 enrichment. ET was determined from the time of canopy closure to crop senescence using a residual energy balance approach over four growing seasons. Elevated [CO2] caused ET to decrease between 9% and 16% depending on year and despite large increases in photosynthesis and seed yield. Ecosystem ET was linked with g(s) of the upper canopy leaves when averaged across the growing seasons, such that a 10% decrease in g(s) results in a 8.6% decrease in ET; this relationship was not altered by growth at elevated [CO2]. The findings are consistent with model and historical analyses that suggest that, despite system feedbacks, decreased g(s) of upper canopy leaves at elevated [CO2] results in decreased transfer of water vapor to the atmosphere.

We found that a germ line denoted as HP3 produces six times more hypericin and fourteen times more pseudohypericin than a second line labeled HP1. We undertook a structural comparison of the two lines (HP1 and HP3) in order to see if there are any anatomical or morphological differences that could explain the differences in production of these economically important metabolites. Analysis by LM (light microscopy), SEM (scanning electron microscopy), and TEM (transmission electron microscopy) reveals that the hypericin/pseudohypericin-containing black glands located along the margins of the leaves consist of a peripheral sheath of flattened cells surrounding a core of interior cells that are typically dead at maturity. The peripheral cells of the HP3 glands appear less flattened than those of the HP1 glands. This may indicate that the peripheral cells are involved in hypericin/pseudohypericin production. Furthermore, we find that these peripheral cells undergo a developmental transition into the gland's interior cells. The fact that the size of the peripheral cells may correlate with metabolite production adds a new hypothesis for the actual site of hypericin synthesis. (c) 2006 Elsevier Masson SAS.

Transcript analysis revealed that both of the integral membrane-acyl-CoA binding proteins of Arabidopsis thaliana, ACBP1 and ACBP2, are expressed in all organs. Expression of ACBP2 was highest in developing roots and flowers, and was four-fold greater than expression of ACBP1. Polyclonal antibodies against recombinant ACBP2 specifically recognized a Mr 47k protein that accumulated to similar levels in A. thaliana leaves, flowers, and siliques (0.05-0.07% total protein), but was two-fold more abundant in roots. To study the potential role(s) of ACBP2 in acyl-CoA metabolism, expression was down-regulated using hairpin RNA interference (RNAi). Three RNAi lines with at least 70% reduced levels of the ACBP2 protein were analyzed, but displayed no gross alterations in growth or developmental phenotype. A systematic analysis of lipids from developing leaves by electrospray tandem-mass spectrometry revealed little change in the levels of the eight major lipid classes but significant changes in fatty acid composition were observed, particularly for the phospholipids. These data suggest a specialized rather than general role for ACBP2 in plant acyl-lipid metabolism. (c) 2006 Elsevier Ireland Ltd. All rights reserved.

Petota; trnV-UAC/ndhC intergenic spacer ID CHLOROPLAST DNA; EUROPEAN POTATO; SEQUENCE; SOLANACEAE; GENOMES; ORIGIN; PETOTA AB Insertions and deletions (indels) are common in intergenic spacer regions of plastid DNA and can provide important phylogenetic characters for closely related species. For example, a 241-bp plastid DNA deletion in the trnV-UAC/ndhC intergenic spacer region has been shown to have major phylogenetic importance in determining the origin of the cultivated potato. As part of a phylogenetic study of the wild potato Solanum series Piurana group we screened 199 accessions of 38 wild potato species in nine of the 19 tuberbearing (Solanum section Petota) series that have not been examined before for indels in the trn-VUAC/ndhC intergenic spacer region. A novel 41 bp deletion (but no 241 bp deletion) was discovered for 30 accessions of three species: S. chiquidenum (5 of 10 accessions), S. chomatophilum (19 of 28), and S. jalcae (6 of 6). Accessions with and without this deletion are found throughout much of the north-south range of all three species in northern and central Peru, but not east of the Maranon River. Multivariate morphological analyses of these 44 accessions showed no morphological associations to the deletion. The results suggest extensive interspecific gene flow among these three species, or a common evolutionary history among species that have never been suggested to be interrelated.

Heynh) and Brassica napus (B. napus L.) seedlings. Here we examined the effect of ectopic BBM expression on the development and regenerative capacity of tobacco (Nicotiana tabacum L.) through heterologous expression of Arabidopsis and B. napus BBM genes. 35S::BBM tobacco lines exhibited a number of the phenotypes previously observed in 35S::BBM Arabidopsis and B. napus transgenics, including callus formation, leaf rumpling, and sterility, but they did not undergo spontaneous somatic embryogenesis. 35S::BBM plants with severe ectopic expression phenotypes could not be assessed for enhanced regeneration at the seedling stage due to complete male and female sterility of the primary transformants, therefore fertile BBM ectopic expression lines with strong misexpression phenotypes were generated by expressing a steroid-inducible, post-translationally controlled BBM fusion protein (BBM:GR) under the control of a 35S promoter. These lines exhibited spontaneous shoot and root formation, while somatic embryogenesis could be induced from in-vitro germinated seedling hypocotyls cultured on media supplemented with cytokinin. Together these results suggest that ectopic BBM expression in transgenic tobacco also activates cell proliferation pathways, but differences exist between Arabidopsis/B. napus and N. tabacum with respect to their competence to respond to the BBM signalling molecule.

TI Enhanced Cd2+-selective root-tonoplast-transport in tobaccos expressing Arabidopsis cation exchangers SO PLANTA LA English DT Article DE cadmium; Arabidopsis cation exchanger; metal-selectivity; tonoplast; tobacco ID METAL TRANSPORT; PLANTS; CADMIUM; GENES; ACCUMULATION; ANTIPORTER; VESICLES; CAX1; OAT; IDENTIFICATION AB Several Arabidopsis CAtion eXchangers (CAXs) encode tonoplast-localized transporters that appear to be major contributors to vacuolar accumulation/sequestration of cadmium (Cd2+), an undesirable pollutant ion that occurs in man largely as a result of dietary consumption of aerial tissues of food plants. But, ion-selectivity of individual CAX transporter types remains largely unknown. Here, we transformed Nicotiana tabacum with several CAX genes driven by the Cauliflower Mosaic Virus ( CaMV) 35S promoter and monitored divalent cation transport in root-tonoplast vesicles from these plants in order to select particular CAX genes directing high Cd2+ antiporter activity in root tonoplast. Comparison of seven different CAX genes indicated that all transported Cd2+, Ca2+, Zn2+, and Mn2+ to varying degrees, but that CAX4 and CAX2 had high Cd2+ transport and selectivity in tonoplast vesicles. CAX4 driven by the CaMV 35S and FS3 [figwort mosaic virus (FMV)] promoters increased the magnitude and initial rate of Cd2+/H+ exchange in root-tonoplast vesicles. Ion selectivity of transport in roottonoplast vesicles isolated from FS3:: CAX4-expressing plant lines having a range of gene expression was Cd2+> Zn2+ >> Ca2+ >> Mn2+ and the ratios of maximal Cd2+ (and Zn2+) versus maximal Ca2+ and Mn2+ transport were correlated with the levels of CAX4 expression. Root Cd accumulation in high CAX4 and CAX2 expressing lines was increased in seedlings grown with 0.02 mu M Cd. These observations are consistent with a model in which expression of an Arabidopsis-gene-encoded, Cd2+-efficient antiporter in host plant roots results in greater root vacuole Cd2+ transport activity, increased root Cd accumulation, and a shift in overall root tonoplast ion transport selectivity towards higher Cd2+ selectivity. Results support a model in which certain CAX antiporters are somewhat more selective for particular divalent cations.

Shiners] when these convert from straight, supple young filaments to stiffened coiled structures in response to touch stimulation. We have analyzed the cell walls of these fibers by in situ localization techniques to determine their composition and possible role(s) in the coiling process. The fiber cell wall consists of a primary cell wall and two lignified secondary wall layers (S-1 and S-2) and a less lignified gelatinous ( G) layer proximal to the plasmalemma. Compositionally, the fibers are sharply distinct from surrounding parenchyma as determined by antibody and affinity probes. The fiber cell walls are highly enriched in cellulose, callose and xylan but contain no homogalacturonan, either esterified or de-esterified. Rhamnogalacturonan-I (RG-I) epitopes are not detected in the S layers, although they are in both the gelatinous layer and primary wall, indicating a further restriction of RG-I in the fiber cells. Lignin is concentrated in the secondary wall layers of the fiber and the compound middle lamellae/primary cell wall but is absent from the gelatinous layer. Our observations indicate that these fibers play a central role in tendril function, not only in stabilizing its final shape after coiling but also generating the tensile strength responsible for the coiling. This theory is further substantiated by the absence of gelatinous layers in the fibers of the rare tendrils that fail to coil. These data indicate that gelatinous-type fibers are responsible for the coiling of redvine tendrils and a number of other tendrils and vines.

Two plasmids, 3.2- and 84.5-kb in size, carrying antibiotic resistance genes were isolated from this strain, and the nucleotide sequences were determined and analyzed. The 3.2-kb plasmid, pU302S, belongs to the ColE1 family and carries the aph (3')-I gene (Kan(R)). The 84.5-kb plasmid, pU302L, is an F-like plasmid and contains 14 complete IS elements and multiple resistance genes including aac3, aph(3')-I, sulII, tetA/R, strA/B, bla(TEM-1), mph, and the mer operon. Sequence analyses of pU302L revealed extensive homology to various plasmids or transposons, including F, R100, pHCM1, pO157, and pCTX-M3 plasmids and TnSF1 transposon, in regions involved in plasmid replication/maintenance functions and/or in antibiotic resistance gene clusters. Though similar to the conjugative plasmids F and R100 in the plasmid replication regions, pU302L does not contain oriT and the tra genes necessary for conjugal transfer. This mosaic pattern of sequence similarities suggests that pU302L acquired the resistance genes from a variety of enteric bacteria and underscores the importance of a further understanding of horizontal gene transfer among the enteric bacteria.

Merr.] plants grown under five management strategies differed significantly in their geometric structures, and were classified with 75 to 100% correct classification, based on differences in their fractal dimension (Do), midday differential canopy temperature (dT), and canopy light penetration [Log(Ho)]. Single soybean plants grown under a conventional system using moldboard tillage developed complex geometric structures, with significantly larger Do (1.477) values and grain yield (11.2 g per plant) as compared to plants grown under an organic system with strip tillage (Do =1.358, and grain yield = 2.32 g per plant). Across management strategies, Do of single plants was a function of stem perimeter, circularity, and volume, and plant dry weight; whereas grain yield m(-2) was a function of Do, plant dry weight and volume, and stem circularity. Knowledge of how plants respond to single and multiple management strategies will help agronomists develop better predictive models and will help farmers refine management practices to optimize yield.

The sorption ability of the BTJF for all metals was much higher than that of untreated juniper. The affinity sequence of both materials, BTJF and untreated juniper, was Ph > Cu > Zn Cd. This order is explained by the hydrolysis constants for each metal. A metal desorption and column regeneration test using 0.1 M nitric acid showed that the metal sorption capacity declined slightly from 136.3 to 119.2 mu mole/g in the first two cycles and then more significantly at the third and fourth regeneration, 72.3 and 83.1 mu mole/g, respectively. Based on the hydraulic conductivity test of BTJF of different size classes, it can be deduced that there is no major headloss-related disadvantage in using BTJF instead of sand as stormwater filter media if the particle size of the BTJF is similar to that for sand.

Polyketides have been shown to play important roles in the life cycles of producing organisms, as well as serving as chemical defense agents. Because a large number of polyketide-derived compounds are biologically active, they have also provided the basis for many important pharmaceuticals of enormous commercial and therapeutic value. Furthermore, the genetic and mechanistic diversity of polyketide synthase enzyme complexes involved in their biosynthesis in different organisms almost rivals the complexity of the molecules themselves. In this chapter, a brief overview is provided on these major subject areas, to serve as an entry point for readers exploring the subsequent chapters in this proceedings volume.

It has been argued that there is a higher likelihood of discovering producers of novel antibiotics among parasitic microorganisms because of the unique adaptive roles adduced to secondary metabolites during the infection, both in overcoming host defenses and in competing with other microorganisms for host resources. The extensive polyketide synthase sequence data available for fungi now makes molecular screening for novel bioactive polyketides a viable alternative to traditional screening approaches. The development, application, and utility of one such screening approach to predict chemistries in insect pathogenic fungi are described herein.

Polyketides are produced by iterative condensation of malonylCoA by a specialized type of fatty acid synthase that often lacks some or all of the reducing domains normally found in such enzymes. Fungal polyketide synthases (PKSs) have a single polypeptide chain with multiple independently acting catalytic domains. The structure of the resulting polyketide depends on the type of coenzymeA (CoA) starter unit upon which the polyketide is built, whether or not reducing domains are present in the PKS, how the polyketide chain is terminated, and the types of oxidative enzymes that perform subsequent modifications. A contiguous set of genes encoding the regulatory and metabolic enzymes is usually required for the biosynthesis of polyketides. The most extensively studied biosynthetic gene cluster is for the carcinogenic mycotoxin, aflatoxin (AF). AF is formed from a hexanoyl CoA precursor by PKS-catalyzed condensation of seven malonyl CoA units and a series of oxidative steps performed by six cytochrome P450 monooxygenases, nine oxidoreductases, and three non-oxidative enzymes. Since there is no evidence that these enzymes are produced sequentially, the subsequent oxidations of the polyketide precursor are most likely dictated by the chemical susceptibility of the individual precursor metabolites formed at each step.

Moench), acts as a potent allelochemical. Its phytotoxic properties make the elucidation of the biosynthetic enzymes participating in this pathway desirable. Previous studies suggest that the biosynthetic pathway of sorgoleone involves a polyketide synthase as well as a fatty acid desaturase, an O-methyl transferase, and a cytochrome P450 monooxygenase. This polyketide synthase is proposed to use a novel long chain fatty acyl-CoA (C16:3) as a starter unit and catalyzes three iterative condensation reactions using malonyl-CoA to form a transient linear tetraketide that cyclizes to form a pentadecatriene resorcinol. To identify the polyketide synthase gene(s) involved in the biosynthesis of these alkylresorcinols, a root-hair specific EST (expressed sequence tag) collection was mined for potential candidates. A total of nine polyketide synthase-like EST's were identified representing five unique contigs, three of which were preferentially expressed in root hairs. The molecular and biochemical characterization of these three candidate polyketide synthases are presented, two of which represent a novel type of type III plant polyketide synthase.

Aflatoxins are toxic and the most carcinogenic natural compounds. In order to better understand the molecular mechanisms that control aflatoxin production, identification of genes involved in aflatoxin biosynthesis employing a genomics strategy in Aspergillus flavus was carried out. Sequencing and annotation of A. flavus expressed sequence tags (EST) identified 7,218 unique EST sequences. Genes that are involved in or potentially involved in aflatoxin formation were identified from these ESTs. Gene profiling using microarray has thus far identified hundreds of genes that are highly expressed under aflatoxin-producing conditions. Primary annotation of the A. flavus whole genome sequence data showed that there are over two dozens of unique polyketide synthase genes. Further investigations on the functional involvement of these genes in aflatoxin biosynthesis are underway. The results are expected to provide information for developing novel strategies to control aflatoxin contamination.

In experiment 1, chicks were challenged orally with a suspension of naladixic acid-resistant Salmonella and wing banded, and additional nonchallenged chicks were placed into each of 2 challenge pens. Nonchallenged chicks were placed into each nonchallenge pen located adjacent to the challenge pens. At 7, 8, 10, and 11 wk of age the litter was sampled using 4 methods: fecal droppings, litter grab, drag swab, and sock. For the challenge pens, Salmonella-positive samples were detected in 3 of 16 fecal samples, 6 of 16 litter grab samples, 7 of 16 drag swabs samples, and 7 of 16 sock samples. Samples from the nonchallenge pens were Salmonella positive in 2 of 16 litter grab samples, 9 of 16 drag swab samples, and 9 of 16 sock samples. In experiment 2, chicks were challenged with Salmonella, and the litter in the challenge and adjacent nonchallenge pens were sampled at 4, 6, and 8 wk of age with broilers remaining in all pens. For the challenge pens, Salmonella was detected in 10 of 36 fecal samples, 20 of 36 litter grab samples, 14 of 36 drag swab samples, and 26 of 36 sock samples. Samples from the adjacent nonchallenge pens were positive for Salmonella in 6 of 36 fecal droppings samples, 4 of 36 litter grab samples, 7 of 36 drag swab samples, and 19 of 36 sock samples. Sock samples had the highest rates of Salmonella detection. In experiment 3, the litter from a Salmonella-challenged flock was sampled at 7, 8, and 9 wk by socks and drag swabs. In addition, comparisons with drag swabs that were stepped on during sampling were made. Both socks (24 of 36, 67%) and drag swabs that were stepped on (25 of 36, 69%) showed significantly more Salmonella-positive samples than the traditional drag swab method (16 of 36, 44%). Drag swabs that were stepped on had comparable Salmonella detection level to that for socks. Litter sampling methods that incorporate stepping on the sample material while in contact with the litter appear to detect Salmonella in greater incidence than traditional sampling methods of dragging swabs over the litter surface.

Poultry and poultry products have been identified as a major source of Campylobacter in human infections. Although many risk factors that contribute to Campylobacter levels have been identified, precise identification of the most effective sites for intervention has not been established. Epidemiological studies have identified that Campylobacter in the broiler breeder's reproductive tract, fertile eggs, and 2- to 3-wk-old broilers has the potential to contaminate day-of-hatch chicks. Numerous studies have shown that day-of-hatch broilers are Campylobacter-negative using conventional culture methods. The purpose of the present study was to demonstrate the prevalence of Campylobacter found in day-of-hatch broilers using a peptone water preenrichment followed by conventional Campylobacter culture methods. Using conventional tray liner (hatcheries) culture methods, the isolation distribution of Campylobacter from 8 commercial broiler hatcheries (n = 2,000) was evaluated. A total of 15 tray liners were positive from 3 different hatcheries. Of the 2,000 chick paper pad tray liners sampled, 0.75% were positive for Campylobacter. These data support previous findings indicating the potential for Campylobacter to be spread by vertical transmission. This is the first time that Campylobacter has been recovered from tray liners collected at commercial broiler hatcheries. C1 USDA ARS, Food & Feed Safety Res Unit, SPARC, College Stn, TX 77845 USA.

Drugs and live vaccines are the 2 main control measures of the disease; however, due to increasing concerns with prophylactic drug use and the high cost of vaccines, alternative control methods are needed. Recent evidence that various dietary and live microbial supplements can influence host immunity against enteric diseases prompted us to investigate the role of a Pediococcus-based probiotic on coccidiosis in broiler chickens. In the present study, we examined BW gains, oocyst shedding, and antibody responses of broilers fed the commercial probiotic MitoGrow. Day-old chicks were fed either a regular broiler diet or 1 of 2 probiotic diets supplemented with 0.1% (MG 0.1) or 0.2% MitoGrow. Chicks were orally challenged with 5,000 or 10,000 sporulated oocysts of Eimeria acervulina or with 5,000 Eimeria tenella oocysts on d 10 or 12 of age, respectively. In E. acervulina-infected birds, the MG 0.1 group improved (P < 0.05) weight gain as compared with the other 2 groups and reduced (P < 0.05) oocyst shedding in birds infected with 5,000 E. acervulina oocysts. In E. tenella-infected birds, Eimeria-specific antibody levels were higher (P < 0.05) in the MitoGrow-fed groups, especially in the MG 0.1 birds, compared with the regular diet group, although their oocyst shedding and weight gains were not clearly improved. These results demonstrate that this Pediococcus acidilactici-based probiotic effectively enhances the resistance of birds and partially protects against the negative growth effects associated with coccidiosis, particularly when supplemented at 0.1% MitoGrow of the diet.

Using RNase-ligase-mediated rapid amplification of cDNA ends PCR, we obtained a cDNA from the broiler small intestine that encodes a type IIb Na-dependent phosphate transporter. The cDNA has an open reading frame of 2,022 by and predicts a 674-amino acid protein with a molecular mass of approximately 74 kDa. Prediction of membrane spanning domains based on the hydrophilic and hydrophobic properties of the amino acids suggests 8 transmembrane domains, with both the NH2 and COON termini being intracellular. The Na-inorganic phosphate (Pi) Ilb cotransporter has relative high homology with other type II Na-Pi cotransporters but low homology with the type I or type III Na-Pi cotransporters. Northern blot analysis demonstrated the presence of a single mRNA transcript present predominantly in the small intestine, with the highest expression in the duodenum, followed by the jejunum and ileum. In situ hybridization indicated that the Na-Pi cotransporter mRNA is expressed throughout the vertical crypt-villus axis of the small intestine. Reduction of P in the diet of chicks from hatch to 4 d of age resulted in a significant induction of Na-Pi cotransporter mRNA expression in the small intestine. Further study is needed to elucidate its physiological role in intestinal phosphate absorption in chickens. C1 Univ Maryland, Dept Anim & Avian Sci, College Pk, MD 20742 USA.

Carcasses were sprayed for 5 s at 80 psi with tap, chlorinated, or EO water in an inside-outside bird washer. Treated carcasses were then stored at 4 degrees C for 0, 3, 7, or 14 d, and the microbial flora of the carcasses was sampled using the whole-carcass rinse procedure. Populations of psychrotrophic bacteria and yeasts in the carcass rinsates were enumerated. Results indicated that immediately after spraying the carcasses, significantly fewer psychrotrophic bacteria were recovered from carcasses sprayed with chlorinated or EO water than from carcasses sprayed with tap water. Furthermore, significantly fewer yeasts were recovered from carcasses sprayed with EO water than from carcasses sprayed with tap or chlorinated water. The population of psychrotrophic bacteria and yeasts increased on all carcasses during refrigerated storage. However, after 14 d of storage, significantly fewer psychrotrophic bacteria and yeasts were recovered from carcasses sprayed with EO water than from carcasses sprayed with tap or chlorinated water, and significantly fewer microorganisms were recovered from carcasses sprayed with chlorinated water than from carcasses sprayed with tap water. Pseudomonas spp. and Candida spp. were the primary microbial isolates recovered from the broiler carcasses. Findings from the present study indicate that EO water can effectively be used in inside-outside bird washers to decrease the population of spoilage bacteria and yeasts on processed broiler carcasses.

Management must monitor the costs of the survey on a routine basis to ensure that actual expenditures do not exceed the budgeted dollar amounts. Management must monitor the progress of the survey on a routine basis to ensure that work will be completed on time. This paper will discuss the automated reporting environment by which cost and progress can be monitored. Given that seven systems must be polled for the information and ten reports must be developed, it becomes difficult for the programmer to comprehend where the data originates for the cells in the reports. A somewhat simple means will be developed to show the cell relationships with-in reports and between reports using a tree structure. Having the cell relationships in the requirements documentation eases the programming burden as well as tracing the final product back to the requirements and specifications.

Epidemiologic studies have shown that a diet rich in cruciferous vegetables such as broccoli is protective against many cancers. Broccoli contains sulforaphane (Sf), a substance that activates promoter elements in certain phase II detoxification enzymes of animals, and upregulation of these genes may increase the rate of clearance of potential carcinogens. Broccoli also accumulates the mineral selenium (Se) and clinical trials have demonstrated that Se may decrease the incidence of prostate and lung cancer. A series of studies have examined the interaction of Se and Sf in broccoli, and the benefit to the health of the animal that consumes broccoli. Selenium-enhanced broccoli reduces the incidence of colon cancer in rats, but increasing the Se content of broccoli results in a corresponding decrease in the Sf content. Sf and Se also interact in the animal that consumes broccoli to upregulate the antioxidant enzyme thioredoxin reductase (TR). TR activity has been shown to be related to oxidative stress in the cell. These studies demonstrate potential problems that may be encountered if a single substance in a plant is targeted for enhancement. They further show that modified plant foods may cause unintended metabolic interactions in the animal that consumes them.

Thus, the story will be only briefly recapped to provide a background for analyzing the major factors that contributed to the timely and practical deployment of the transgenic papaya in Hawaii. Several important factors were: 1) starting the biotechnology research before PRSV became a large problem in Hawaii, 2) focusing on getting a practical result, 3) blend of expertise of the research team, 4) small but consistent support, and 5) the era in which the transgenic papaya was deregulated and commercialized. Since its commercial release in Hawaii in 1998, the transgenic papaya has occupied a major portion of Hawaii's papaya industry, and is commonly accepted among consumers in Hawaii. Starting in 1992, efforts to move transgenic papaya beyond Hawaii were started with collaborative efforts of our laboratory with scientists in Brazil, Venezuela, Jamaica, Thailand, Bangladesh, and east Africa. Other laboratories have also made great strides in the technical development of PRSV-resistant transgenic papaya. These projects have advanced very well technically, but they are still far from reaching the ultimate goal of deregulation and commercialization. Why is this? A personal assessment on the present situation and the future of moving beyond the Hawaiian experience will be given. C1 USDA ARS, Pacific Basin Agr Res Ctr, Hilo, HI 96720 USA.

J. M., and S. N. Prasad. 2006. Agricultural Water Management. 86:196-205). Several simplifying assumptions were made. The model consists of a two-component process of Darcian matrix flow and Hortonian flow on the walls of the cracks. Model assumptions include: (1) Water enters into the soil horizontally from the vertical cracked surfaces exclusively by diffusive flow, (2)Vertical infiltration through the soil surface was negligible because of a severe surface sealing condition, (3) Water flow along the vertical surfaces of the cracks is uniform over its circumference, and (4))Wetting front advance interactions between adjacent vertical crack surfaces are assumed to be negligible. These assumptions will be examined and their effect on infiltration will be assessed. Also, alternative approaches involving different modular concepts for predicting infiltration and incipient ponding estimates will be examined. C1 [Roemkens, M. J.

Line fire was initiated in single species fuel beds of four common chaparral plants under various fuel bed configurations and ambient conditions. An LES approach was developed to model fire spreading through a fuel bed with a subgrid scale turbulent combustion model based on a flame surface density concept. By examining two fuel bed slope configurations, it was found that upslope fire spread depends not only on the increased radiant heat transfer but also on the aerodynamic effect created by the interaction of the flame with the inclined surface. Under certain conditions, the convective heat transfer induced by this interaction becomes the dominant mechanism in determining fire spread Success. Seventy-three (or 42%) of 173 experimental fires successfully propagated for slopes ranging from -70% to 70%. It was found there exists a critical slope above which fire spread in these live fuel beds was successful, and below which fire spread was unsuccessful. This critical slope for marginal burning varied widely with fuel moisture content and fuel loading. A stepwise logistic regression model was developed from experimental data to predict the probability of successful fire spread. It is expected that this model may be helpful in providing guidelines for prescribed fire application. (c) 2006 The Combustion Institute. Published by Elsevier Inc. All rights reserved.

Although corrective treatments such as foliar or dormant sprays with Zn are available, they have serious limitations, and when repeated over many years may potentially lead to environmental contamination. Using genetic means to increase apple rootstocks' efficiency to acquire Zn from the root environment creates the possibility to eliminate the need for applying Zn fertilizers. Such an approach, however, necessitates the development of an effective and precise method of assessing the efficiency of apple germplasm to acquire Zn from the rhizosphere. The method presented herein relies on the use of chelator-buffered nutrient solutions in which the level of Zn activity is precisely controlled and buffered with a strong chelator such as diethylenetriamnine pentaacetate (DTPA). This system proved quite effective in inducing varying degrees of Zn deficiency in 'Red Delicious' apple seedlings in both stationary and re-circulating nutrient solution systems. The deficiency was confirmed by tissue chemical analyses. In the re-circulating system, however, microbial build-up and apparent adsorption of chemicals were observed on tubing walls through which the nutrient solution was circulated. The data suggest that these two factors may lead to the removal of DTPA from the nutrient solution. Therefore, effective methods of preventing these phenomena must first be devised before the re-circulating system can be recommended for screening plant germplasm. These difficulties, however, posed no problem in the stationary system. Using a computerized chemical equilibrium model (GEOCHEM-PC) and the data obtained from the stqionary nutrient solution system, we calculated that 10(-9.95) M is the critical Zn+2 activity level needed to produce normally growing apple plants containing optimal levels of Zn in their tissues. It is therefore concluded that all future assays for Zn acquisition by apple plants should employ Zn activities in the rhizosphere that are lower than this critical level to identify germplasm of varying degree of resistance to Zn stress.

(Reticulatus group); ascorbic acid; beta-carotene; color; KCI; maturity; firmness; sugars; soluble solids AB Cantaloupe [Cucumis melo L. (Reticulatus Group)] fruit quality (ascorbic acid, beta-carotene, total free sugars, and soluble solids concentration (SSC)) is directly related to plant potassium (K) concentration during fruit growth and maturation. During fruiting, soil fertilization alone is often inadequate due to poor root uptake and competitive uptake inhibition from calcium and magnesium. Foliar applications of glycine-complexed K during cantaloupe fruit development has been shown to improve fruit quality, however, the influence of organic-complexed K vs. an inorganic salt form has not been determined. In this study, the effects of two K sources; glycine-complexed K vs. KCl (with or without a surfactant) were studied following application of K during fruit growth and maturation of glasshouse grown orange-flesh cantaloupe 'Cruiser'. Plants were fertilized throughout the study with soil-applied N-P-K fertilizer. Flowers were hand pollinated and only one fruit per plant was allowed to develop. Starting at 3 to 5 d after fruit set, and up to 3 to 5 d prior to fruit maturity (i.e. full slip), entire plants were sprayed weekly, including the fruit, with a glycine-complexed potassium (Potassium Metalosate, 24% K diluted to 4.0 mL.L-1) or KCl, (24% K diluted to 4.0 mL.L-1) with or without a surfactant. Fruit from plants receiving supplemental foliar K were firmer, both externally and internally, than those from non-treated control plants. Increased fruit tissue firmness was accompanied by higher cell pressure potentials of K treated plants vs. control. In general, all K treated fruit had significantly higher SSC, total sugars, total ascorbic acid, and beta-carotene concentrations than control fruit. Autumn grown fruit, generally had higher SSC, total sugars, total ascorbic acid and beta-carotene concentrations than spring-grown fruits regardless of K treatment. There were no consistent differences among the K sources (with or without surfactant) on these fruit quality parameters, however, addition of a surfactant tended to increase SSC and betacarotene in some instances.

Lycopene is the pigment that imparts red color to some fruits, most notably tomato and watermelon. It is also a highly efficient oxygen radical scavenger and has been implicated in human studies as providing protection against cardiovascular disease and some cancers, particularly that of the prostate. Watermelons contain as much or more lycopene than tomatoes but have been little studied. Over the last six years, we have conducted numerous studies with watermelon to evaluate germplasm, storage and minimal processing effects on lycopene levels. Additionally, we conducted a cooperative human clinical study with watermelon and tomato juice to determine lycopene uptake in humans. Assays of human plasma after watermelon ingestion indicated that lycopene was as bioavailable from watermelon juice as from tomato juice. Citrulline and arginine are amino acids found in watermelon and are major components of the human nitrous oxide system and help regulate many biochemical processes. Citrulline lacks biological importance on its own but is transformed by the human body into arginine. Arginine is used in the nitric oxide pathway to help in vasodilatation and overall cardiovascular health. Our recent work with citrulline identified that it is present in watermelons in the peel, rind, and flesh. Following the lycopene human clinical trial we measured the citrulline levels in the human plasma from the subjects who ingested watermelon juice. Plasma levels of citrulline were highest in subjects who consumed six cups of watermelon juice per day. Further studies with these unique compounds found in watermelon are ongoing.

The flourishing of the fresh-cut produce industry is attributable to the high value placed by modern consumers on foods that are fresh, nutritious, and convenient. However, the recent food borne illness outbreaks associated with the consumption of packaged fresh-cut produce have also made bold headline news worldwide. Unlike the intact fruits and vegetables, fresh-cut produce sustains substantial tissue injury during processing, and is thus more susceptible to microbial growth and quality deterioration; unlike traditionally processed food, fresh-cut products consist of living tissues and are processed and marketed as "ready-to-eat" yet without a microbial killing step. In addition, fresh produces grow in the open field, and contamination with human pathogens can potentially occur anywhere from farm to table. These factors reduce the shelf-life of fresh-cut produce and increase the risk of food borne illness. This paper discusses the challenges facing the industry and scientific community. Issues involved in maintaining both quality and safety of fresh-cut produce, their current status and future research directions will be emphasized.

A series of experiments were undertaken to establish horticultural relationships to carotenoids in watermelon and mango in cooperation with U.S. commodity boards. Watermelon was assayed to determine effects of germplasm, storage temperature, and fresh cut on lycopene and beta carotene content. Seedless watermelons were generally highest in lycopene and storage at 21 degrees C increased both lycopene and beta carotene contents. Fresh cut watermelon lost about 6% of carotenoids, probably through oxidation of cut surfaces. Mangos of the five major varieties imported over a 12 month period into the U.S. from Peru, Mexico, Brazil, and Ecuador were ripened at 20-25 degrees C and assayed for beta carotene and vitamin C content. Beta carotene content (mg/kg fwt) averaged 5.0, 7.0, 10.4, 16.8, and 26.1 for 'Tommy Atkins', 'Haden', 'Keitt', 'Kent', and 'Ataulfo', respectively. Total vitamin C (mg/100 g fwt) was 19.2 ('Tommy Atkins') to 126.4 ('Ataulfo'). Results of our experiments show that U.S. watermelons are a rich source of lycopene while mangos imported into the U.S. offer consumers a new natural source of beta carotene and vitamin C.

While ripening brings about highly desirable changes in fruit character and chemistry in terms of flavor, appearance, texture and nutrition, the advanced stages of ripening lead to sub-optimal fruit quality and eventually post-harvest loss. Fruit biologists have studied numerous fruiting species with the intent of identifying strategies and technologies toward improving desirable ripening attributes while minimizing those with negative consequences. Tomato has emerged as a model for fleshy fruit ripening, in part due to its ease of use as a model system resulting from facilitating attributes including simple genetics, numerous characterized mutants, cross-fertile wild germplasm to promote genetic studies and routine transformation technology. In the last decade, the tomato system has been further complemented with molecular and genomic tools including dense genetic maps, large EST collections and the recently initiated genome sequencing effort. The isolation of genes corresponding to several previously described tomato ripening mutations has led to considerable advancement of a genetic regulatory model of fruit ripening while emerging genomics technologies promise exceptional opportunities for continued advancement of this field.

For the past decade and a half, laboratory experiments have shown that site-specific recombination can delete genomic DNA, regulate gene expression, recombine chromosomes, and target new DNA into designated transgenic loci. Although much of the technology was once viewed as futuristic promises, commercial adoption of at least a first application is underway. New transgenic crops with the antibiotic resistance marker removed through site-specific recombination are due to appear in the marketplace. This translation from laboratory research to improved field varieties has been slowed by a combination of factors, including the long development time in crop genetic engineering. This paper discusses future potential applications in recombinase-based plant transformation, and in particular, a gene stacking strategy that may be used by Agrobacterium-based delivery of the integrating DNA.

Four main genetic groups of cacao are traditionally described: Criollo, Trinitario, and lower and upper Amazon Forastero. During the 17(th) and 18(th) centuries, plants derived from a small number of parents were distributed to many tropical regions of the world, resulting in commercial plantings with a narrow genetic base. Production of cacao in tropical America has been severely affected by two fungal pathogens causing diseases known as witches' broom (WB) and frosty pod (FP). These, along with another pan-tropical fungal disease, black pod (BP), were responsible for over 700 million USD in losses in 2001. Currently, WB and FP are confined to tropical America; however, commercial populations in West Africa and South Asia are highly susceptible to both diseases. Traditional cacao breeding programs have only been marginally successful in producing resistant material with suitable commercial characteristics. In 1999, the USDA-ARS in collaboration with Mars Inc. initiated a project to apply modern molecular genetic techniques to cacao breeding. The objectives were to develop an international Marker Assisted Selection (MAS) breeding program focusing on disease resistance, to identify new sources of resistance in unexploited germplasm, and to identify the genes involved with disease resistance. Over 320 microsatellite and 50 candidate gene markers are being used to map families segregating for resistance to WB, FP, and BP diseases. Quantitative Trait Loci (QTL) have been identified for resistance to WB and FP and these are being employed in MAS. The utility of Association Mapping for productivity traits has been demonstrated providing an alternative method to traditional mapping. Microsatellite and candidate gene markers have also been used to estimate the genetic diversity in over 1,300 individuals representing 70 different domesticated and semi-domesticated/ wild cacao populations. Genetic diversity has been found to be much higher in the semi-domesticated/wild populations from the upper Amazon which may contain new sources of disease resistance. For the gene discovery effort, a Bacterial Artificial Chromosome (BAC) library has been produced from 'LCTEEN37', resistant to WB, and work is underway to identify and sequence gene(s) responsible for a major WB QTL. Large evaluation trials, developed using MAS, are located in Costa Rica, Ecuador, Brazil, and Papua New Guinea with additional QTL evaluation studies in Ghana, Nigeria, Costa Rica, and Ecuador. All these projects are collaborations with national agricultural institutes in the respective countries. The international MAS project is expected to produce new disease resistant cultivars by 2012. Genetic stocks developed in this project will be distributed to areas currently free of WB and FP in anticipation of the arrival of these diseases. International collaboration and sharing of genetic resources will ensure that crop losses due to these pathogens are manageable and will contribute to stability in the supply of cocoa beans.

In particular, freeze injury can result in the loss of an entire crop or even an entire orchard. Over the past two decades, significant advances have been made in understanding the genetic regulation of cold hardiness, as well as resistance to other abiotic stresses. At first, research focused on isolating and characterizing cold-regulated (cor) genes and then advanced to the discovery of cold-induced transcription factors and the characterization of cold-induced changes in whole genomes using microarray technologies. Metabolomics, and proteomics have also provided a wealth of new information on the metabolism and biochemistry of cold acclimation. In fruit trees, and woody plants in general, cold hardiness is a complex trait and a thorough understanding of the physiology of freezing tolerance is needed if biotechnology is going to be used effectively to improve environmental stress resistance. The factors that limit cold hardiness in mid-winter are very different from those that are responsible for frost susceptibility in the spring. In contrast to what is observed in herbaceous crops, tissues in woody plants that are in very close proximity to each other can differ dramatically in cold hardiness and the mechanisms by which they cold acclimate. For example, xylem tissues are generally less cold hardy than bark tissues, and the flower buds of some fruit crops exhibit deep supercooling, a freeze-avoidance mechanism that relies on the biophysical properties of the bud tissues. Therefore, different approaches will be needed to influence cold resistance depending on the type of injury (mid-winter or spring) and tissue-type (buds vs. stems) that is being targeted for improvement. Despite this complexity, significant opportunities exist for improving resistance to environmental stress in fruit crops. The targeting of dehydrin proteins to flower buds and the use of transcription factors to regulate suites of genes are two approaches. Additionally, the overexpression of antixodant enzyme (APX or SOD) genes is also a viable approach to improving resistance to several environmental stresses. Recent genomic and proteomic research on stress response in fruit trees is also being used to develop a more comprehensive understanding of environmental stress resistance.

The estradiol-induced XVE gene expression system was cloned into a binary vector (pBinPlusARS) compatible for use in Agrobacterium-mediated transformation of apple. To evaluate the estradiol-inducible binary vectors, a GUS marker gene was cloned into pBinPlusARS.XVE and pBinPlusARS.XVE.Gateway. When evaluated in tobacco under non-inducing conditions, GUS expression from the GUS containing XVE constructs was indistinguishable from that of an empty vector (no GUS coding region) negative control. However, in the presence of estradiol, GUS expression from the GUS containing XVE constructs was greater than that from a 35S promoter positive control. To evaluate the activity of the light inducible promoter of the peach chlorophyll a/b binding (CAB) protein and XVE in transgenic apple, binary vectors were constructed to allow comparison of test promoter activity with 35S activity.

Corrective foliar sprays and/or soil applications of Zn are only partially effective and may elevate Zn in the soil to levels of regulatory concern. The goal of this work is to elucidate the feasibility of increasing the uptake and transport of Zn to the aboveground parts by constitutively over-expressing Zn transporter genes in 'M.26' apple rootstock. Clones containing the coding regions of Zn transporter genes ZNT1 or ZIP4 were ligated along with a dual 35S promoter into a pBIN+ARS plasmid vector. Agrobacterium-mediated transformation was used to introduce the gene construct into in vitro apple explants of 'M.26' rootstock. The ability of three transgenic lines, T4 (ZNTI), T5 (Vector Control), T6 (ZIP4) and untransformed 'M.26', to absorb Zn were evaluated in a greenhouse, using diethylenetriamine pentaacetic acid (DTPA) chelator-buffered nutrient solutions containing low (2 mu M) or optimal (24 mu M) Zn concentrations. Plants grown under the low Zn level showed Zn deficiency symptoms and had reduced growth. The overexpression of ZIP4 and ZNT1 transporter genes in 'M.26' apple rootstock had very limited and no effect on the plants' Zn nutritional status, respectively. The overexpression of ZIP4, but not the ZNT1 transporter gene, consistently increased the concentration of Ca and Cu in all roots and aboveground tissues, thus indicating enhanced uptake and transport of these elements. The fact that ZIP4 was expressed to a greater extent than ZNT1, corroborates the increased tissue nutrient concentrations of the T6 (ZIP4) line.

Understanding flower induction in tree crops is often difficult since trees are a long-term perennial crop that is subject to environmental and cultural changes over multiple seasons of growth. Unlike temperate fruit trees, where growth, dormancy and break of dormancy is determined by the seasons, subtropical and tropical fruit trees rely on more subtle changes in rainfall, temperature or nutrient availability. The discovery of potassium chlorate induced flowering in longan provides an excellent opportunity to investigate the mechanism of flowering in longan. Preliminary experiments suggest that chlorate inhibits nitrate reductase activity in longan trees treated with potassium chlorate, however there is no significant difference in the total nitrogen content and carbon:nitrogen (C:N) ratio in potassium chlorate treated and untreated trees. In addition to potassium chlorate, sodium chlorite and sodium hypochlorite are also able to effectively decrease nitrate reductase activity and induce flowering of longan trees. To identify genes that may be involved in potassium chlorate induced flowering, we created a suppressive subtractive hybridization (SSH) library to longan cDNAs that are differentially expressed in vegetative buds or floral buds induced by potassium chlorate.

A goal of our program is to determine if delaying the production of ethylene in ripening fruit will result in fruit that remain firm while developing tree-ripened flavors. Plum hypocotyls were transformed with an antisense construct of a peach ACC oxidase gene (responsible for the last step in ethylene formation) under the control of the 35S promoter. Eighteen lines were derived from four genetically different hypocotyls from `Bluebyrd' and three from `Stanley'. DNA blot data indicated that the majority of these lines had single insertions of the peach antisense ACO gene. Wound ethylene responses were measured on the seedlings in the greenhouse and after one year of growth in the field. Several of the transgenic lines had consistently reduced ethylene responses while a few had increased ethylene responses. Fruit quality data, consisting of firmness, color, date of ripening, brix, and size as well as ethylene production rates were measured for two years on the fruiting lines. Analyses of the data suggested that in some transgenic lines, ethylene production was delayed relative to the `Bluebyrd' parental line and that softening was also delayed. Sugar levels were on the average lower in most of those lines as well. C1 USDA ARS, Appalachian Fruit Res Stn, Kearneysville, WV 25430 USA.

It is an approach that can specifically target genetic improvements and allow for the development of novel, useful traits. While GE does not provide a panacea for all of the difficulties associated with fruit tree breeding, it can be a useful approach to increase the efficiency and effectiveness of breeding programs. In spite of the potential utility of GE for fruit tree improvement, the technology has not, to date, been widely exploited in these species. Of over 11,000 field tests of transgenic plants in the United States between 1987 and 2004, less than 1 % have involved fruit tree species. Transgenic plum trees that are highly resistant to Plum pox virus(PPV) are one example of GE that can be of significant benefit to growers and consumers while providing unique genetic material for use in conventional breeding programs. The development and testing of this plum has spanned 15 years and included researchers in five countries. Currently this plum, 'HoneySweet', is being evaluated for deregulation by U.S. regulatory agencies so that it may possibly be released in the future to breeders and growers who are concerned about the threat of PPV to U.S. stone fruit production.

Genes encoding stilbene synthases have previously been described for several plant species including grapevine. Pierce's disease (PD), anthracnose and downy mildew are the limiting factors for growing European grape (V. vinifera) in the southeastern United States. Native American grape species such as V. shuttleworthii, V. aestivalis and V. rotundifolia present strong resistance to these diseases. In order to understand the role of StSy in grapevine disease resistance, several hundred stilbene synthase gene sequences from among ribs species were retrieved from the NCBI database. These stilbene synthase sequences were blasted against about 9,000 unigenes of V. shuttleworthii grape. Homologous relationships among the stilbene synthase (StSy 1) from five Vitis species were analyzed by multiple alignments.

Anthocyanins are responsible for flower, leaf and seed coat color in plants, and are antioxidants as well. However, little is known about anthocyanin content in Clitoria ternatea, Desmodium adscendens, Corchorus olitorius, Catharanthus roseus, Hibiscus sabdariffa and Acer saccharum. This study was conducted to identify anthocyanin indexes and additional health enhancing components in these species. An anthocyanin meter with an LED diode of 520 nm was used to measure the anthocyanin index of leaves and flowers from plants growing in the field during July, September and October 2006. We found anthocyanin indexes ranging from 4.1 to 52.4 for leaves and 0.8 to 26.8 for flowers in all five species. The highest leaf anthocyanin index average of 14.6 was found in D. adscendens (PI 316623) followed by sugar maple (A. saccharum) with a leaf anthocyanin average index of 13.0. Catharanthus roseus (PI 608581) also had the highest flower anthocyanin index average of 17.3. These data were recorded at or prior to 50% maturity. In addition, potential health uses for these species are discussed. Phytochemicals identified include but are not limited to an antimicrobial protein from C. ternatea, anthocyanin rich extracts from H. sabdariffa for potential use as a chemopreventive agent, and antitumor promoters in C. olitorius leaves. These anthocyanins and phytochemicals have potential value in the nutraceutical and medical industries. Theme variable anthocyanin indexes among these species will assist breeders and other scientists with valuable germplasm for development of anthocyanin enriched cultivars. C1 [Morris, J. B.; Wang, M.

Continuous distributions for sucrose were observed in the F-2 populations indicating quantitative inheritance for the trait. A significant positive correlation was found between sucrose and total soluble solids (TSS). Nine RAPD markers were detected to be significantly associated with QTL for sucrose in the F-2 population of the 'TAM Dulce' x TGR1551 cross in the greenhouse based on simple linear regression. Five unlinked markers associated with QTL were significant in a stepwise multiple regression analysis where the full model explained 39% of the total phenotypic variation for sucrose. Three to five of the nine RAPD markers were also observed to be significantly associated with QTL for glucose, fructose and TSS, respectively, suggesting that in this cross four sugar traits are controlled by the same QTL. Four RAPD markers were confirmed in the F-2 population of the 'Deltex' x TGR1551 cross in the field to be consistently associated with sucrose QTL. A significant association of a with sucrose was consistently expressed in our populations under greenhouse and field environments. C1 [Park, S. O.; Sinclair, J. W.; Crosby, K. M.; Yoo, K.

Bulb crops such as Gladiolus suffer from viruses because they are propagated vegetatively. Viruses in Gladiolus result in streaking of the flower and cause decreased vigor of the plant. There are no commercial cultivars of Gladiolus that are resistant to virus for breeding so an alternative strategy is to develop virus resistant plants using genetic engineering. One problem encountered when genetic engineering of Gladiolus is that the only promoter found to express at high levels is the CaMV 35S promoter. A polyubiquitin promoter isolated from Gladiolus (GUBQ1) has been shown to express at levels comparable to the CaMV 35S promoter in cells following transient transformation. This promoter was tested by transient transformation in other floral crops including Freesia, Lilium (lily), Canna and Rosa hybrida (rose), and the levels of GUS activity were comparable to the CaMV 35S in freesia and rose. Transgenic Gladiolus plants containing the uidA gene under control of the GUBQ1 promoter have been found to show GUS expression in the leaves, roots, and callus derived from the transgenic plant.

This water balance is computed for the present climate and for future climates with changed temperatures and precipitation. With this procedure, the contribution of glaciers to the total runoff and the yearly loss of glacier ice in a warmer climate can be more accurately determined than by just considering the overall increase of annual runoff volume. The Illecillewaet Basin in British Columbia, Canada (1155 km(2), 509-3150 m a.s.l.) was selected for this study because of a significant glacial melt component in the runoff. For a tempera lure increase of 4 degrees C, an additional 134.2 center dot 10(6)m(3) of today's glaciers (in terms of water) in this basin would be melted in a year. This amount would be reduced as the glacier area gradually diminishes in the next decades. C1 USDA ARS, Las Cruces, NM 88003 USA.

In 2005, about 3.6 million NIT of strawberries were produced in 75 countries. Fragaria, which includes about 26 species, has centers of diversity located in Eurasia and North and South America. The primary cultivated gene pool is octoploid. Landraces have been lost though human encroachment, natural disasters, and displacement by commercial cultivars. Geneticists have bred new strawberry cultivars for more than 300 years but the primary cultivated gene pool is restricted. A global conservation strategy is in preparation to reduce the erosion of diversity in wild genetic resources and to protect the availability and accessibility of the wild and cultivated gene pools. An international team of strawberry genebank managers, geneticists and researchers is defining protocols to specify protocols for sustainable and secure conservation of strawberries in perpetuity. A survey of ex situ collections of strawberry was performed to identify the present status of genebank activities. Technical guidelines for the safe movement of Fragaria germplasm were reviewed and updated. Eligibility criteria for genebanks to be recognized as part of the global conservation system will be established. A unified approach for the global conservation of Fragaria will be suggested.

Most of those accessions were acquired internationally at a time when genetic resources were often exchanged informally, free of charge or other restrictions, and were viewed as abundant and part of humanity's common heritage. During the last 20 years, several national and international trends shifted the norms for germplasm exchange. Access to and exchange of plant genetic resources have become increasingly formal and sometimes more restricted. Acquiring new samples for the NPGS from domestic and international sources became increasingly complicated and in some cases problematic. In contrast, acquiring samples from the NPGS in general became easier because of computerized databases and communication, and more reliable and rapid long-distance transport. Consequently, the volume of NPGS samples distributed annually expanded steadily, to a current average of about 120,000 per year, free of charge or restriction. About 1/4 of total distributions are exported from the U.S. The current ratio of six NPGS samples exported internationally for every new sample imported by the NPGS will likely increase as research programs that use plant genetic resources grow in other nations. More of the samples conserved and distributed by the NPGS will be genetic stocks generated by large-scale genomics and biotechnology research projects, and elite, previously proprietary, varieties and hybrids that move into the public domain when their limited-duration intellectual property rights expire. Additional changes in NPGS holdings may occur in the future as the norms for international exchange of genetic resources evolve in concert with national and international trends in scientific research, and the evolution of access and benefit-sharing regimes.

It can be less labor intensive and more reliable for preventing the loss of plants to disease than multiplying plants in the field or in vitro. The objective of this study was to develop a cryopreservation procedure to preserve our transgenic lines of Gladiolus without growing them each year under the special conditions required for cultivation of genetically engineered plants. Shoot tips, including its meristem were excised from in vitro-grown cormels of cultivars 'Peter Pears' and 'Jenny Lee' and field-grown breeding lines 02-943A, 02-900, and 02-926. Cormels were stored at 4 degrees C for at least six months prior to their use. Excised shoot meristems, 1-2 mm, from all five genotypes were cultured on MS medium supplemented with either 2.0 mg/L kinetin, 0.5 mg/L BA, 0.5 mg/L iPA, 0.5 mg/L BA combined with 0.5 mg/L NAA, 0.5 mg/L iPA combined with 0.5 mg/L NAA, or without hormones. A maximum 70-100% regrowth of the excised shoot tips occurred for the five genotypes. Both 'Peter Pears' and line 02-943A were then used for vitrification. The highest regrowth of shoot tips (54%) using the cultivar 'Peter Pears' was achieved when the shoot tips had been incubated for 2 h in PVS2. Regrowth of vitrified shoots from breeding line 02-943A was only 15% indicating the need to optimize conditions for each genotype. All shoots that survived vitrification showed a phenotypically normal growth in vitro. C1 [Joung, H. Y.; Cantor, M.; Karno, K.] USDA ARS, Florist & Nursery Plants Res Unit, Beltsville, MD 20705 USA.

Since that time, the Shrub Research Consortium and other forums have addressed various aspects of wildland shrub ecosystem biology and management. Shrubs occur in most vegetation types but are dominants only in those habitats that place plants under considerable stress. Three primary, often interacting factors, that promote shrubby habitats are drought or aridity, nutrient-poor soils, and fire. Other stress factors that may also be interactive that contribute to the shrubby habitat are shade, poor soil aeration, winter cold, short growing season, and wind. Most of these conditions frequently occur in semi-arid, temperate, continental climates. The principal shrubland ecosystems of the western United States are sagebrush, chaparral, mountain brush, coastal sage, blackbrush, salt desert, creosote bush, palo verde-cactus, mesquite, ceniza shrub, shinnery, and sand-sage prairie. Similar as well as distinctively different shrubland ecosystems occur at other locations around the world. Shrubland ecosystems have different human and wildlife values and have, and are, subject to changing environmental conditions including different fire regimes. Fragmentations of these ecosystems, for example the sagebrush ecosystems, are of concern since some ecosystem components are at critical risk. Shrubland ecosystem changes have become more apparent in recent decades posing significant ecological and management problems.

Fire suppression activities in the past century have increased the number and severity of wildfires, resulting in increased soil erosion and decreased water quality. Many infiltration studies on rangeland have shown that litter and vegetation cover protect the soil and enhance infiltration. After fire, water repellency is typically found on the soil surface or a few centimeters below and is also common on unburned rangelands and dry soils conditions. However, the causal agents of water repellency are different for burned and burned conditions. Rainfall simulation studies were conducted for 3 consecutive years immediately following a catastrophic wildfire in Denio, Nevada, in 1999. Study sites were chosen on north-facing hillslopes (35 to 40 percent slope) where the vegetation was dominated by mountain big sagebrush (Artemisia tridentata ssp. vaseyana). The objective of this study was to use indirect gradient analysis on the 1999 data to evaluate and summarize pertinent relationships between vegetation, soil, topographic features, infiltration, runoff, sediment production, and microsite distinction (shrub coppice and interspace) on burned and unburned areas. The first ordination (strategy 1) used four infiltration parameters and the results were unexpected. In the multivariate context, higher infiltration trends were associated with the burned treatment compared to the unburned treatment. Water repellency on the burned sites was apparent at the soil surface; however, it appears that repellency was also a significant factor on the unburned area. Water repellency in the unburned treatment was likely caused by assorted litter buildup (up to 11,605 kg/ha) in > 80-year stands (sagebrush duff and grass in the shrub coppice areas and grass litter in the interspace). The second ordination (strategy 2) involved the same four infiltration parameters, but specifically used plots from the burned treatment. More runoff and sediment was associated with the burn shrub coppice plots; in contrast, higher infiltration capacity in the burned interspace. The third ordination (strategy 3) was based on plant canopy cover by species. Discrete taxa of native grasses, forbs, and shrubs were correlated with infiltration, runoff, and sediment loss on burned and unburned sites. On the unburned sites, water repellency and higher runoff was correlated with Sandberg bluegrass (Poa secunda), bluebunch wheatgrass (Pseudoroegneria spicata), and western aster (Symphyotrichum ascendens). Greater infiltration capacity was correlated with increasing cover of Idaho fescue (Festuca idahoensis) and mountain big sagebrush. Future analysis will evaluate conditions after the first years growing season and beyond. C1 [Spaeth, Kenneth E.] USDA, NRCS, Ft Worth, TX USA.

Runoff is generated more quickly and a larger volume of runoff is produced following prescribed fire. The result is increased risk of severe erosion and downstream flooding. The Water Erosion Prediction Project (WEPP), developed to model erosion on cropland, forest, and rangeland, is a tool that has the potential to model erosion and help managers address erosion and runoff risks following fire. WEPP views erosion as two processes: interrill and rill. Experimental results on a steep (35 to 50 percent slope) sagebrush site suggest that rill erosion is the dominant erosion process following fire and must be adequately understood so that models can provide reliable predictions. Evaluation of WEPP parameterization equations using data from steep burned sagebrush rangelands suggests that critical parameter estimation procedures within WEPP need improvement to include fire effects on infiltration and rill erosion processes. In particular, rill detachment estimates could be improved by modifying regression-estimated values of rill erodibility. In addition, the interactions of rill width and surface roughness on soil grain shear estimates may also need to be modified. In this paper we report the effects of prescribed fire on runoff and soil erosion and compare WEPP estimated erosion for several modeling options with measured erosion.

No research has addressed the behavior of larger seeded, hypogeal invasive plants (common in south Texas) exposed to elevated CO2. We studied two such species, guajillo (Acacia berlandieri Benth.) and cat claw acacia (Acacia greggii Gray var. wrightii (G. Bentham) D. Isley), to quantify growth stimulation at a doubled concentration of CO2. Seedlings were grown in glasshouses in 1.5 m tubes at Temple, TX, in the late summer of 2000. Only seeds within a narrow range of masses were selected for each species, to reduce effects of seed mass on seedling size. Plants were harvested 15 days after emergence. Leaf area, shoot weight, leaf weight, root weight, and depth of root penetration were determined for each plant. Both species exhibited marked root length at sampling, with mean values of about 75 and 90 cm for guajillo and cat claw acacia, respectively. For both species, all parameters demonstrated a positive numerical response to elevated CO2 although no differences were statistically significant. The lack of statistical verification of the observed differences was likely caused by the great deal of variability observed within both species. For example, values for specific parameters varied by as much as a factor of six within a species and CO2 treatment. These results suggest that seedling growth responses to elevated CO2 may be smaller in hypogeal than in co-occurring epigeal species. C1 [Tischler, Charles R.; Derner, Justin D.; Polley, H.

Shrubs and grasses of southwestern deserts are colonized by symbiotic fungi that cannot be removed by conventional sterilization methods. These fungi were extensively studied in Bouteloua eriopoda (Torr.) Torr. and Atriplex canescens (Pursh) Nutt. over a wide range of locations and environmental conditions. Fungi were intrinsically integrated with cells, tissues, and regenerated plant cultures. These composite plant-fungus organisms are comprised of more than one fungal species. Fungal association with photosynthetic cells and accumulation of lipids provide evidence for carbon management. Fungal biofilms that coat cells, tissues, roots, and leaves suggests protection of plants from direct exposure to stressed environments. Associations with vascular tissues suggests a role in resource transport. Association with stomata indicates an influence in gas exchange, photosynthesis, and evapo-transpiration. Transfer of fungal endophytes from native plants to non-host plants resulted in substantial modifications in root, shoot morphology and biomass, chlorophyll content, and fruiting. Host plants are modified by fungi at the genetic, cellular, and physiological level and positively enhance ecological fitness. C1 [Barrow, J.

We examined the effects of biological crust-forming algae and arbuscular mycorrhizal fungi on growth and survival of Ephedra viridis (EPVI), Coleogyne ramosissima (CORA), Artemisia filifolia (ARFI), Chrysothamnus nauseosus ssp. hololeucus (CHNA), and Artemisia nova (ARNO), with and without competition from cheatgrass, in a controlled laboratory pot experiment. Shrub survival declined as soil fertility increased. Few shrubs were able to survive in competition with cheatgrass in fertilized growth medium. Under low nutrient conditions, the addition of mycorrhizal inoculum intensified competition with cheatgrass, reducing shrub shoot biomass over that of the control treatment in all species except ARFI. However, shoot growth of cheatgrass in the mycorrhizal treatment was reduced to an even greater extent in all cases except when grown with ARNO. Algal inoculation increased shrub survival and appeared to beneficially affect the growth of ARFI and EPVI at the expense of cheatgrass. Our findings suggest that soil microorganisms can, to some extent, improve shrub establishment in the presence of cheatgrass.

J.T Howell, common winterfat, is valued for its nutrient content and palatability to livestock; however, the subspecies Ceratoides lanata var. subspinosa (Rydb.) J.T. Howell, ('subspinosa') is considered unpalatable. Curiously, observations of 'subspinosa' revealed several populations in central New Mexico that were heavily grazed. Volatile terpene profiles are associated with differences in palatability in many plant species. To determine whether differences in volatile profiles between 'subspinosa' populations would correlate with apparent differences in palatability, plants from 13 populations of 'subspinosa' were collected. Volatile analysis of shoot samples identified 33 compounds. Limonene, myrcene, and 3-carene were the most abundant volatiles in all populations, comprising 81 percent and 85 percent of the volatiles detected in heavily grazed and ungrazed plants, respectively. Compounds present in at least half of either the heavily grazed or ungrazed plants were subjected to a stepwise discriminate analysis of relative quantities. The analysis identified a subset of 14 chromatographic peaks (myrcene, 3-hexenol, 3-Garene, AR-curcumene, limonene, n-hexanol, p-cymene, a mixture thought to contain alpha-pinene, alpha-thujene, and tricyclene, a mixture thought to contain n-decanal, and five unknowns), which may distinguish between palatable and unpalatable phenotypes. When a discriminate rule based on these chemicals was applied to chemical data from individual plants at all sites, none of the plants were misclassified. The possibility that these varied oil profiles may be used to distinguish palatable from unpalatable phenotypes is discussed.

We studied viability and germinability of fourwing saltbush seeds over 10 years for collections from 23 Intermountain populations. Fruit fill averaged 53 percent, and 96 percent of filled fruits contained viable seeds even after 6 years of laboratory storage. Seed collections were generally dormant to some degree at harvest and lost dormancy via two processes, moist chilling and after-ripening in dry storage. Prolonged chilling (24 wks) substituted for dry after-ripening, resulted in germination percentages similar to those obtained without chilling after 2 years of storage. Collections from warm desert habitats were generally least dormant, while collections from pinyon-juniper and mountain brush habitats were highly dormant. But these trends were not very strong. Seeds of the diploid population from Jericho Dunes were essentially nondormant at harvest, while those from a population near Page, Arizona, were essentially completely dormant. Unchilled seeds did not germinate to any degree until tested after 10 years of storage. Patterns of dormancy loss suggest that this species is opportunistic and generally able to establish in response to either winter or summer precipitation. In addition, its seeds probably form persistent seed banks in the field. C1 [Meyer, Susan E.; Carlson, Stephanie L.] US Forest Serv, USDA, Rocky Mt Res Stn, Shrub Sci Lab, Provo, UT USA.

It was found that long-term continuous cultivation of C. beijerinckii BA101 in a degermed corn based medium was not possible due to the instability of the gelatinized degermed corn starch during storage often called "retrogradation". Using this substrate, continuous ABE fermentation was run for 228 h, before the fermentation turned acidogenic. However continuous fermentations of saccharified degermed corn with normal and half P2 medium nutrients were successful. In saccharified degermed corn continuous fermentation, ABE concentration up to 14.28 g/L was achieved at a dilution rate of 0.03 h(-1). This work demonstrated that byproduct (germ/oil, corn fiber) credit can be obtained by fermenting saccharified degermed corn in continuous flow bioreactors. Additionally significant savings can be achieved by supplementing with half of normal P2 medium nutrients. (c) 2006 Elsevier Ltd. All rights reserved.

Bulk sediment fractions are not generally preferred because they contain an unknown mixture of organic material of variable age, they may contain dead carbon such as lignite that is difficult to eliminate, and material of aquatic origin may be subject to reservoir effects. If the various processes that contribute carbon to the system are relatively constant over time, however, changes in C-14 activity with depth may be used to accurately estimate sediment accumulation rates even if the absolute ages are erroneous. In this study, fine-grained fractions (250-710 mu m organic material, humic acids extracted from < 250-mu m fraction, and untreated < 250-mu m fraction combusted at low temperature) were analyzed and compared with terrestrial plant stems (twigs), charcoal, and wood fragments in sediments from an oxbow lake in Mississippi, USA. The C-14 activities of the bulk fractions were highly linear with depth and produced consistent calculated sediment accumulation rates similar to, and perhaps more reliable than, rates determined using twigs or charcoal.

TI Integrating ranch forage production, cattle performance, and economics in ranch management systems for southern Florida SO RANGELAND ECOLOGY & MANAGEMENT LA English DT Article DE forage; grazing; beef cattle; stocking density ID BODY CONDITION; QUALITY AB The presence of grazing cattle near open waterways has created environmental concerns related to the potential for water contamination. In Florida the removal of cattle from grazing landscapes or decreasing stocking density is being investigated as one option to improve the quality of surface water runoff draining into Lake Okeechobee, Florida. The objective of this study was to determine the effects of stocking rate on cow-calf performance, forage availability and quality, and ranch economic performance. Experimental pastures were established on a southern Florida cow-calf operation with stocking rates of 0.58, 1.01, and 1.35 ha . cow(-1) on summer pastures and 0.93, 1.62, and 2.16 ha . cow(-1) on winter pastures, corresponding to high, medium, and low rates, respectively. The study was conducted over 4 consecutive production years. Cow body condition scores (BCS), pregnancy rate, and calf average daily gain were used as measures of animal performance. Forage utilization was estimated by measuring the difference between forage yield inside and outside grazing exclusion cages and forage quality by crude protein and in vitro organic matter digestibility. Forage yield, utilization, and quality were not significantly affected by stocking rate. Although statistically not significant (P = 0.17), cattle in the high stocking rate experienced a numerically greater loss of BCS following the winter grazing period, but stocking rate did not affect pregnancy rate or calf gains. Production (kg weaned calves . ha(-1)) was increased (P < 0.01) for a high stocking rate compared with medium and low stocking rates. Overall ranch profitability will decrease as stocking rates decline. Ranch revenues decrease one-for-one as stocking rates decrease. At the same time, unit cow costs increase at an increasing rate as fewer brood cows are left to support the ranch's fixed cost structure.

Our objectives were: 1) to evaluate late summer/early fall forage quality of crested wheatgrass (Agropyron desertorum [Fisch. ex Link] J. A. Schultes), bluebunch wheatgrass (Pseudoroegneria spicata [Pursh] A. Love), Idaho fescue (Festuca idaboensis Elmer), bottlebrush squirreltail (Elymus elymoides [Raf.] Swezey), Thurber's needlegrass (Achnatherum thurberianum [Piper] Barkworth), and basin wildrye (Leymus cinereus [Scribn. & Merr.] A. Love) from ungrazed paddocks and paddocks grazed at vegetative, boot, and anthesis; and 2) test hypotheses that postgrazing regrowth yields were correlated with soil moisture content when grazing occurred. Crop-year precipitation for 1997 and 1998 was 134% and 205% of average. Crude protein (CP) and in vitro dry matter digestibility (IVDMD) of ungrazed grasses displayed expected declines in quality. Among ungrazed grasses, late summer/ early fall CP was 5.7% in 1997 and 3.6% in 1998; IVDMD was 47% and 41%, respectively. Late summer/early fall forage quality was elevated by vegetative, boot stage, or anthesis grazing. The phenologically youngest regrowth always ranked highest in CP and IVDMD. Among grasses, respective 1997 CP and IVDMD means were 9.0% and 55% for regrowth following anthesis grazing. No regrowth followed anthesis grazing in 1998, but CP and IVDMD means from boot stage treatments were 5.5% and 47%, respectively. With CP measures, a species by treatment interaction occurred in 1997, bur species reacted similarly in 1998. Vegetative, boot stage, and anthesis grazing in 1997 caused respective late summer/early fall standing crop reductions of 34%, 42%, and 58%; and 34%, 54%, and 100% reductions in 1998. Forage conditioning responses were lower for bluebunch wheatgrass and crested wheatgrass than other grasses. Soil moisture content was a poor predictor of regrowth yields. Managed cattle grazing can successfully enhance late season forage quality. C1 ARS, USDA, Eastern Oregon Agr Res Ctr, Burns, OR 97720 USA. Oregon State Univ, Coll Vet Med, Corvallis, OR 97331 USA.

Shatter date was strongly correlated to elevation (r = 0.74) and an equation that included elevation, latitude, longitude, and longitude squared explained 79% of the variation in seed shatter dates. In general, earlier shatter dates were associated with more southerly latitudes, easterly longitudes, and lower elevations. Examination of climatic data confirmed the expectation that earlier shatter dates were associated with warmer sites. This information can assist those needing to schedule seed collection activities at multiple locations. C1 US Forest Serv, USDA, Forestry Sci Lab, Corvallis, OR 97331 USA.

Control occurs by altering an animal's behaviour through one or more sensory cues administered to the animal after it has attempted to penetrate an electronically-generated boundary. This boundary can be of any geometrical shape, and though unseen by the eye, is detected by a computer system worn by the animal. The most recent autonomous programmable systems use radio frequency (RF) signals, emanating from global positioning system (GPS) satellites to generate boundaries. Algorithms within a geographic information system (GIS) within the device's computer use the GPS and other data to determine where on the animal a cue, or cues, should be applied and for how long. The first commercial virtual fencing system was patented in 1973 for controlling domestic dogs. Virtual fencing was used for the first time to control livestock in 1987. Since then proof-of-concept research using commercial, as well as custom designed systems have demonstrated that virtual fencing can successfully hold as well as move livestock over the landscape. Commercial virtual livestock control systems do not yet exist but research continues towards this goal. Pending research needs relating to this method of animal control are discussed in light of currently available technologies. C1 New Mexico State Univ, USDA ARS, Las Cruces, NM 88003 USA.

We have quantitated the amount of proteinase K-resistant prion protein (PrP 27-30) by use of nano-scale liquid chromatography coupled to tandem mass spectrometry using the multiple reaction monitoring mode of operation. We used a method based on the detection of VVEQMCTTQYQK (residues 209-220) obtained by reduction, alkylation and digestion with trypsin. Quantitation of the amount of PrP 27-30 in the brains of Syrian hamsters was possible as early as 24 h after inoculation. Our results show sensitive detection of 180 fmol of PrP 27-30 per g brain (wet weight) as early as 24 h after inoculation. Clinical symptoms are not observed until 9 weeks after inoculation.

One of the objectives of the Soil Moisture Experiments in 2004 (SMEX04) and 2005 (SMEX05) were to develop and test algorithms for a vegetation water content data product using shortwave infrared reflectances. SMEX04 studied native vegetation in Arizona, USA, and Sonora, Mexico, while SMEX05 studied corn and soybean in Iowa, USA. The normalized difference infrared index (NDII) is defined as (R-850 - R-1650)/(R-800 + R-1650), where R-850 is the reflectance in the near infrared and R1650 is the reflectance in the shortwave infrared. Simulations using the Scattering by Arbitrarily Inclined Leaves (SAIL) model indicated that NDII is sensitive to surface moisture content. From Landsat 5 Thematic Mapper and other imagery, NDII is linear with respect to foliar water content with R-2 = 0.81. The regression standard error of the y estimate is 0.094 mm, which is equivalent to about a leaf area index of 0.5 in m(2) m(-2). Based on modeling the dynamic water flow through plants, the requirement for detection of water stress is about 0.01 mm, so detection of water stress may not be possible. However, this standard error is accurate for input into the tau-omega model for soil moisture. Therefore, NDII may be a robust backup algorithm for MODIS as a standard data product. C1 [Hunt, E.

Measurements of erythemally weighted UV radiation at the sites of the United States Department of Agriculture UV-B Monitoring and Research Program (UVBMRP) monitoring network were analyzed to investigate the geographical distribution and seasonal variations. Twenty nine observation sites, which had continuous measurements during the recent six years, are selected for this study; twenty seven of them are distributed in the United States, including one in Hawaii and one in Alaska, and two of them are located in Canada along the United States border. The measurements were taken using the Yankee Environmental Systems Inc. (YES) UVB-1 ultraviolet pyranometer. This work focuses the data from the recent six years of 2001-2006 and the measurements during summer months (June-August) are emphasized. For each day, the measurements are integrated from sunrise to sunset to produce the daily UV dosage, which is then averaged for different seasons or for the whole year over the six years to generate the average daily UV dosage. A multivariable regression technique is exploited to characterize the dependence of UV dosages on geographical parameters, including latitude and altitude. The results show that, although there are many factors, such as clouds, ozone, aerosols, air pollutants, and haze, that affect the UV radiation intensity at a location, the latitude and altitude of the site are the primary factors that regulate the average daily UV dosage. On average over the last six years in the United States, more than 95% of the variability in averaged daily UV dosages can be explained by the latitude and altitude. Longitude is not statistically significant in predicting UV irradiance. Nonlinear relationships can be statistically established between averaged daily UV dosage and latitude and altitude. The effects of latitude on UV radiation are much more significant than the altitude. The average daily UV dosages decrease exponentially with the latitude. While an increase of one degree in latitude may lead to a decrease of more than 350 Jm(-2) day(-1) in the averaged daily dosage in the low latitudes, the decrease is around 100 Jm(-2) day(-1) in the mid latitudes and less than 50 Jm(-2) day(-1) in the high latitudes. The averaged daily UV dosage increases with altitude almost linearly until up to 1500 meters. Then it increases gradually and no significant increases can be detected above 2600 meters. Although the regression against latitude and altitude is statistically highly significant, notable deviations from the regression predictions are observed in the lower and mid latitudes and lower altitudes. These discrepancies are most likely due to the intense anthropogenic activities and natural events occurring in this area, including natural fire, industrial production, driving, and farming. These locally dependent activities will generate more UV absorbers into the air.

Data at forty-two observation sites among 160 sites are chosen for the analysis. The China domain is broadly divided into northeastern, northwestern, and Tibet regions. The results show that the evolution of snow depth and area is in good agreement with that from previous studies using different datasets. An abrupt jump occurred in the year 1990. Oscillations with a wavelength of about five years can be identified in the time sequence. Significant correlations between snow depths, snow covers, temperatures, and precipitation are found for various time frames at different sites. The cold air mass comes from the northwestern and northeastern China and moves into the southern China through an aisle between them. This cold air transportation brings the influence of snow information on the temperature and precipitation into the southern China. In the sensitive. region, the snow information in the three regions has strong effects on the temperature and precipitation. The actual effect of snow information on temperature and precipitation is the result of competition among these three snow covered regions. The snow information in the Tibet region has a larger scale effect on the temperature and precipitation than in the other two regions. This is in accordance with its characteristics that are able to inspire the larger scale atmospheric circulations.

Application of TsHARP to coarse (I km) resolution thermal data over the rainfed agricultural area is found to produce reliable fine/within-field (60 in) resolution ET estimates, while in contrast, the TsHARP algorithm applied to the irrigated area does not perform as well, possibly due to significant sub-pixel moisture variations from irrigation. As a result, there may be little benefit in applying TsHARP for generating TSM-derived 60 m ET maps for the irrigated compared to the rainfed region. Consequently, reliable estimation of fine/within-field ET and crop stress still requires fine native resolution thermal imagery in areas with significant sub-pixel moisture variations.

Such models reflect that key land base changes such as afforestation and deforestation are driven by quite different socioeconomic factors. The prototype area-change modeling system-the AREACHANGE projection system-was constructed in the early 1980s for the South to support a special study between periodic RPA Timber Assessments. The southern prototype involved an area-base econometric approach, which has been applied in later RPA Timber Assessments regions and revised for the South. Other econometric models were developed in the late 1980s and later decades for the Pacific Northwest, Lake States, Maine, and other regions. Timber price projections from the Timber Assessment Projection System's modeling of markets are used as inputs in the first stage of the area-change projections. Timber harvest projections from the TAMM model, as allocated to management units by the ATLAS model, along with timber management projections from the ATLAS model are used as inputs in the second stage of projecting area changes in major forest cover types. The AREACHANGE system provides the ATLAS system with projections of timberland area by region, ownership, and major forest type. The progression of area-change modeling was heavily dependent on the availability of land-use data. C1 [Alig, Ralph J.] US Forest Serv, USDA, Pacific NW Res Stn, Corvallis, OR 97331 USA.

In the Timber Assessment Projection System these modules represent aggregates of stands across a region and ownership with multiple management regimes. ATLAS employs an age class structure to represent the timber inventory for areas managed on both even- and unevenaged silvicultural systems. Inventory is represented by means of strata or units which are aggregations of basic plot-level data to some higher geographic or other descriptive level. Yield projections are derived from type-specific growth models in some regions and from empirical yield relations derived from basic inventory data in other instances. Yield projections are adapted to reflect both even- aged and partial cutting regimes. Allocation of private lands to various levels of management intensity depends on a model of management investment based on estimated land expectations values. Section 6.4 contrasts ATLAS with inventory projection approaches employed in other recent forest sector models. C1 [Mills, John R.] US Forest Serv, USDA, Pacific NW Res Stn, Portland, OR 97209 USA.

Do we have enough resources to meet current and future wants? Can we describe the sustainability of forest resources in the face of increasing demand? Can we identify emerging problems while there is still time to design programs to offset them? Each of the Timber Assessments pictured the future in ways that strongly reflected contemporary views about key drivers of future conditions. Each also evolved in its reliance on underlying models of economic processes to both structure the development of projections and to increase the confidence that can be placed in individual projections. The Timber Assessments have covered a variety of issues, some short term and others that are enduing and universal to forest sectors worldwide. Some of these enduring issues include: how to increase timber supplies before increases in product price reduce consumption excessively, the role that improved harvesting or processing technologies can play in increasing supplies and employment opportunities, how forest growth can be increased through improved forest management, how different land ownership patterns influence forest management, and the role of markets in allocating resources and providing incentives for both improved processing technology and forest stewardship.

Public harvest in the USA rose during the 1960s and 1970s as timber management programs were established to meet rising domestic wood needs. Harvest fell sharply in the 1990s as management focus shifted toward the provision of ecosystem services. The Timber Assessment Projection System is employed to examine what might have happened if public cut had not fallen in the 1990s and what could happen in the future if a program of restoration thinning were implemented on the national forests. Results of these simulations are consistent with past analyses in showing the importance of substitution across regions, owners, and products in damping the impacts of public cut changes at the national level, even though local effects may be large.

Is this a reasonable expectation, and how important are these investment inputs in shaping the projected future? Historical data on management inputs are limited. Planting and plantation area data suggest a fairly clear trend of intensifying management on forest industry lands in the South and Pacific Northwest West. The picture is less clear for nonindustrial private owners, although in the South this group's inventory and harvest have risen steadily since the late 1950s. Simulations examine the impact of alternative investment assumptions on the projections, considering both an extreme case of no future shifts in types or management intensity classes and a case freezing only plantation establishment in the South.

It discusses drivers of economic globalization and related structural changes in US forest product markets, including currency exchange rates and differences in manufacturing costs that have contributed to the displacement of global manufacturing capacity. It includes detailed discussion of paper and paperboard trends. Bilateral trade flows between the USA and Canada for all wood products, were modeled within the Timber Assessment Projection System, with currency exchange rate assumptions among key elements influencing projected trade. This chapter describes how assumptions about globalization and trade influenced model results, using examples of recent RPA Timber Assessments. Techniques and results of the Timber Assessment Projection System models are compared to those of a more general global trade model, the Global Forest Products Model (GFPM). The GFPM was used recently to project international forest sector developments conditional on the 2000 RPA Timber Assessment. The results showed that while the USA, Japan, and Europe were predicted to remain major importers of forest products out to 2030, the rapid economic growth of China would make it the world's largest market for raw wood and intermediate and final forest products. In a separate study, exchange rate assumptions were found to be important determinants of major US trade flows as projected by GFPM, particularly for manufactured commodities such as pulp and paper.

These analyses suggested that forest ecosystems would be seriously impacted by climate change, with consequent impacts on the forest sector. It was not until the mid-1990s that the ecological and the economic impacts were first modeled together at the national scale. The RPA Timber Assessment was the first national timber assessment model to include climate change scenarios impacting forest productivity and the forest sector. The modeling treatment of climate change included exogenous analyses of climate change impact on ecosystem productivity under various climate change scenarios and linked such analyses to the forest sector modeling system. These analyses and the work that built on this approach suggest the importance of integrating ecological dynamics with the economic in the assessment of climate change on forests.

This chapter explores methods used to reflect this pattern of technological change and others in the Timber Assessment Projection System models. The development and use of three types of technology projection methods are explained: (1) decomposition of technology into several processes and projection of future mixes of processes to make exogenous projections of technology change for harvesting costs and for solidwood products recovery and processing costs in TAMM; (2) activity analysis that uses alternate technologies capable of changing fiber input mixes to make endogenous projections of technology change for pulp, paper, and paperboard production in NAPAP; and (3) innovation diffusion modeling to endogenously project the change in wood-use rates in major end uses such as housing in TAMM. We provide an example of a sensitivity testing in a case where technology projections were made exogenously. Finally we discuss lessons learned and points to consider when deciding the type of technology projection methods to use. C1 US Forest Serv, USDA, Forest Prod Lab, Madison, WI 53726 USA.

A base case and alternative scenarios were simulated using the AREACHANGE projection system. Historical changes include forest area reductions in some regions due to conversion of forests to agricultural uses, such as to cropland on nonindustrial private ownerships. In the future, however, reduction in forest land area is projected to result mainly from conversion to developed land uses such as urban expansion, highway and airport construction, surface mining, and reservoirs. However, a major source of uncertainty surrounding land-use change is future agricultural and climate change policies, including any directed at marginal agricultural lands. Changes in the areas of forest cover types often result from differences in land management objectives among owners and reflect the combined influence of natural forces and human-caused management actions. A key projected change is an increase in the area of pine plantations in the South, including on marginal agricultural land. The area of pine plantations responds over time to projected domestic timber harvest levels and prices, and also reflects effects from international markets, such as rising imports that affect prices for Southern timber. One area of uncertainty affecting future forest area and distribution among different forest cover types is global climate change. For example, expanding forest area through afforestation of economically marginal agricultural lands is one approach to reduce net emissions of carbon dioxide in the USA and other countries.

The history of families previously placed in the Pyraloidea is discussed. The group now includes about 16,000 species worldwide. Morphologically, the superfamily is defined by a basally scaled proboscis and the presence of abdominal tympanal organs. The larvae of many species are economically important pests of crops (e. g.: sugarcane, corn, rice), and stored products such as seeds and grains. Currently 22 subfamilies comprise the Pyraloidea; only the 19 subfamilies that occur in the Western Hemisphere are discussed. There is a paucity of recent research using cladistic methods and phylogenetic analyses across all taxa. C1 USDA, Natl Museum Nat Hist, Syst Entomol Lab, Smithsonian Inst, Washington, DC 20013 USA.

Picaridin and AI3-37220 exhibit polychiral diastereoisomerism and each has four diastereoisomers due to the presence of two asymmetric centers in their molecules. The diastereoisomers of these compounds have differing degrees of mosquito-repellent activity according to quantitative behavioral assays conducted at the United States Department of Agriculture. An insight into the stereochemical requirements for repellency is of great importance in the development of better repellents. Molecular overlay of the optimized geometries of the diastereoisomers was considered as a novel tool for Stereochemical Structure-Activity Relationship (SSAR) modeling. An earlier study using molecular mechanics (MM2) optimized geometries showed good promise. In continuation of this effort and to overcome certain defects in using MM2 geometries, a hierarchical overlay approach was developed. In this method geometry of the low energy conformer of each diastereoisomer was optimized using: the following quantum chemical methods in a graduated manner: (a) semiempirical AM1, (b) Hartree Fock (STO3G, 3-21G, 6-31G, and 6-311G), and (c) Density Functional Theory (B3LYP/6-31G, B3LYP/6-311G). The optimized geometries of different diastereoisomers were overlaid in various user defined combinations to calculate the root mean square distances (RMSD) of the overlaid structures. The RMSD with respect to the most active diastereoisomer (220SS) were found to have a strong relationship with biological potency. Common motifs in shapes and molecular surfaces that are probably critical for effective repellent activity were identified. The hierarchical approach gave valuable information on the quantum chemical level (basis set) at which optimization must be carried out to get the correct order of repellency of the diastereoisomers of Picaridin and 220.

Our objective was to study the regulatory factors on the mobilization of storage N and fatty acids in soybean cotyledons of seeds during post-germinative growth. Cotyledons contributed 58% of their dry mass to support seedling growth at 9 clays after imbibition (DAI). The mobilization of the storage reserves in cotyledons during post-germinative growth revealed that fatty acids decreased more rapidly than N. The presence or absence of testa had no effect on reserve mobilization, while light, gibberellic acid (GA) and seedling axis sink significantly affected the mobilization of storage reserves. Growth in light promoted the mobilization of both N and fatty acid although the seedling length was shorter than those grown in the dark. Inhibition of GA biosynthesis by paclobutrazol (PAC) reduced storage reserve mobilization while exogenous GA reversed the inhibitory effect of PAC. Gibberellic acid promoted storage reserve mobilization indirectly by promoting seedling growth, but also by direct regulation of the mobilization of storage reserves.

SO SEEDS: BIOLOGY, DEVELOPMENT AND ECOLOGY LA English DT Proceedings Paper CT 8th International Workshop on Seeds CY MAY, 2005 CL Brisbane, AUSTRALIA SP Australian Soc Plant Sci, Bayer CropSci, Griffith Univ Ctr Forestry & Horticultural Res, ISSS AB A wild weedy strain (i.e. SS18-2) of Oryza sativa L. was selected to investigate the genetic architecture underlying seed dormancy. A framework genetic map covering the whole rice genome was constructed based on a backcross population (i.e. BC(1) [EM93-1 (non-dormant breeding line)//EM93-1 /SS18-2]). Dormancy was determined by germination of seeds after 1, 11 and 21 days after ripening (DAR). Six dormancy quantitative trait loci (QTLs), designated as qSD4, 6, 7-1, 7-2, 8 and 12, were identified. The locus qSD7-1 was tightly linked to the red pericarp colour gene Rc. In addition, the locus qSD4 was associated with an interval imparting black bull colour. A QTL x DAR interaction was detected for qSD12, the locus with the highest effect at 1, 11 and 21 DAR (R(2) = 14%, 24% and 20%, respectively). Two and more (i.e. three and four) orders of epistases were detected with four and all the six QTLs, respectively. The higher-order epistases strongly suggest the presence of genetically complex networks in the regulation of variation for seed dormancy in natural populations, and make it critical to select a favourable combination of alleles at multiple loci in positional cloning of a target dormancy gene. Backerossing techniques in combination with phenotypic and marker-assisted selection are being used to introduce the weedy rice-derived dormancy locus qSD7-1 into the EM93-1 genetic background to develop near isogenic lines for fine-mapping and positional cloning.

The biological functions of miRNAs are important for developmental processes in plants and animals. Little is known about the functions of miRNAs in seeds. To gain a better understanding of the regulation of gene expression in seeds, it is necessary to characterize gene regulation by miRNAs, which are known to play significant roles in other plant organs and tissues. A simple method for isolating small RNAs from seeds and a non-radioactive detection system for seed-expressed miRNAs have been established earlier. In this study the established seed miRNA detection techniques, as well as a new method to isolate developing Arabidopsi thaliana (L.) Heynh. seeds from siliquae for miRNA analysis, are introduced. The information on miRNAs expressed in Arabidopsis and Lycopersicon esculentum NO. and their target genes is also updated. C1 [Martin, R. C.] USDA ARS, NFSPRC, Corvallis, OR 97331 USA.

In this paper, a prototype of a wavelength-changeable two- and three-band color-mixing device is presented and its application is demonstrated. The wavelength-changeable device uses changeable central wavelength bandpass filters and various filter arrangements. The experiments showed that a color-mixing technique implemented in a pair of binoculars coupled with an imager could greatly enhance target identification of color-blindness test cards with hidden numbers and figures as the targets. Target identification of color blindness cards was greatly improved by using two-band color-mixing with filters at 620 nm and 650 nm, which were selected based on the criterion of uniform background. Target identification of a different set of color blindness test cards was also improved using three-band color-mixing with filters at 450 nm, 520 nm, and 632 nm, which were selected based on the criterion of maximum chromaticness difference. These experiments show that color-mixing techniques can significantly enhance electronic imaging and visual inspection.

Since measuring these changes is expensive, it is likely that many countries will use alternative methods to prepare these estimates. We reviewed seven well-known soil carbon models from the point of view of preparing country-scale soil C change estimates. We first introduced the models and explained how they incorporated the most important input variables. Second, we evaluated their applicability at regional scale considering commonly available data sources. Third, we compiled references to data that exist for evaluation of model performance in forest soils. A range of process-based soil carbon models differing in input data requirements exist, allowing some flexibility to forest soil C accounting. Simple models may be the only reasonable option to estimate soil C changes if available resources are limited. More complex models may be used as integral parts of sophisticated inventories assimilating several data sources. Currently, measurement data for model evaluation are common for agricultural soils, but less data have been collected in forest soils. Definitions of model and measured soil pools often differ, ancillary model inputs require scaling of data, and soil C measurements are uncertain. These issues complicate the preparation of model estimates and their evaluation with empirical data, at large scale. Assessment of uncertainties that accounts for the effect of model choice is important part of inventories estimating large-scale soil C changes. Joint development of models and large-scale soil measurement campaigns could reduce the inconsistencies between models and empirical data, and eventually also the uncertainties of model predictions.

Diets were 65% concentrate (CON 15% CP, DM basis) and coarsely ground alfalfa hay (FOR 23% CP). There were no significant interactions between genotype and diet. ME intake was similar between genotypes and greater (P < 0.05) for CON versus FOR both when intake was ad libitum (7.60 versus 5.43 MJ/day) and near maintenance (4.31 versus 4.09 MJ/day). DE concentration was greater (P < 0.05) for CON than for FOR with ad libitum (74.4 versus 55.5%) and restricted intake (77.0 versus 59.6%). Energy expenditure (EE), determined by respiration calorimetry, at all levels of intake was similar between genotypes. EE was greater (P < 0.05) for CON than for FOR at each of the three levels of intake, ad libitum (573 and 521 kJ/kg BW0.71 while fasting), near maintenance (426 and 400 kJ/kg BW0.75) and fasting (280 and 255 kJ/kg BW0.75). Efficiencies of ME utilization for maintenance (k(m)) and gain (k(g)) and the ME requirement for maintenance (MEm) were similar between genotypes. k(m) was similar between diets (0.705 and 0.690 for CON and FOR, respectively), although kg was greater (P < 0.05) for CON than for FOR (0.603 versus 0.387). MEm was numerically greater (P < 0.17) for CON than for FOR (407 versus 379 kJ/kg BW0-75), which may have involved higher ME intake with CON. In conclusion, under the conditions of this experiment energy requirements and efficiency of utilization were not different between growing Boer crossbred and Spanish goats regardless of diet quality.

We compare the conceptual and operational development of the constructs of community capacity and community resiliency used in three community assessments in the western United States: the Forest Ecosystem Management Assessment Team, the Sierra Nevada Ecosystem Project, and the Interior Columbia Basin Ecosystem Management Project. The policy mandates, research goals, and methodologies of the assessments are considered in order to better understand the evolution of these constructs. We compare the constructs and find them similar in concept but slightly different in application. We suggest further conceptual refinement of community capacity and resiliency by distinguishing foundational assets from mobilizing assets. We present several methodological and theoretical challenges that, if overcome, may increase the effectiveness and relevance of community capacity or community resiliency as constructs in social science research and social assessment projects.

Soils were treated with aqueous solutions of Termidor (fipronil) at concentrations of 0, 0.12, 0.25, 2.5, 5.0 and 20.0 ppm (wt AI: wt soil) that brought the soils to 15% moisture. Estimated lethal concentrations (ppm) required to kill 50% of termite workers within 96 h after placement on the soils were: 0.49 (sandy loam), 0.70 (sand), 4.21 (loamy sand), and 6.99 (silt loam). Termite mortality decreased with increases in organic matter content of the soils treated with fipronil. C1 USDA, Forest Serv, Starkville, MS 39759 USA.

Acoustical detection of termite activity illustrated termite mortality over time, attributed to termiticides moving from donors to recipients. In the first of two donor-recipient experiments, worker termites (donors) were exposed for 1.0 h to sand treated with 50 ppm concentrations of fipronil or imidacloprid. Donors were then combined with recipients at 5% of the total population of 200 workers. Termite activity was monitored for 14 d. Only fipronil significantly reduced termite activity (sound events), survival, and wood consumption below controls. In a second donor-recipient experiment, fipronil significantly reduced activity, survival, and consumption below controls when donors (12.5% of the population) were exposed to 1.0 ppm for 1.0 h.

Monitoring stations were checked for the first time after Hurricane Katrina in October of 2005. The percentage of active stations in October 2005 post-Katrina was 54% compared to 59% of stations occupied by termites in August 2005 pre-Katrina. None of the nine monitoring stations that had been occupied by Reticulitermes spp. pre-Katrina was active with Reticulitermes spp. in October 2005 and three of these stations were active with C.formosanus. The percentage of stations occupied by termites in August 2006 was significantly lower than in August 2005. However, there were no significant differences in the percentage of stations occupied by termites in August 2005, October 2005, and October 2006. Laboratory bioassays were conducted to examine how flooding affected the tunneling systems of termites kept on different substrates for different lengths of time. All of the termites drowned when containers were flooded after termites spent I wk in containers. However, there were survivors in containers flooded after termites spent 4 and 8 wk in containers. These results provide evidence that the presence of carton material can improve termite survival in flooded areas. C1 USDA ARS, So Reg Res Ctr, New Orleans, LA 70124 USA.

Mound volume and height were measured prior to treatment and at 1 and 2 d after treatment. Condition of the mound surface was rated according to an index ranging from 0 (no evidence of recent building or repair activity) to 3 (recent building or repair activity over > 50% of mound surface). Treatments had small but significant effects on mound volume and height; in general, watering reduced volume over time (< 1 L except in mounds that received an inverted bucket, and bucket placement had a slight positive effect on mound height while watering had a slight negative effect. Differences over time within treatments were very small (< 10 mm). The most significant effect was observed on the condition of the mound surface, with the index increasing over time following application of water. Characteristics of S. invicta Buren (red imported fire ant) mounds were also measured over time under natural conditions from late July through mid-October, 2006. Mound height and volume were negatively correlated with temperature, and mound height was positively correlated with rainfall. The results of these studies indicate that in late summer, rainfall triggers mound rebuilding and repair but not a significant increase in size, which occurs as temperatures decrease into fall.

In natural habitats, this harvester termite forages for plant material that is then stored in underground nests. In order to use bait technology for the delivery of biorational control agents, we needed to determine the plant species most preferred for feeding by the termites which can be used as a base to develop a bait matrix. Of the 15 materials tested in the laboratory, and 25 in the field, stems of the sunflower Helianthus annus and sweet sorghum Sorghum saccharatum showed consistently high consumption in both tests. In general, grasses and annuals were more preferred than shrubs and trees. The common reed Phragmites australis was the least consumed grass species. C1 Inst Zool, Tashkent 700095, Uzbekistan.

The influence of cryolite crystal size [0 (control), 0.2, and 20 mu m diameter particles] on the overall mortality of termites consuming the bait was determined in forced feeding bioassays. Only baits containing 20 mu m diameter cryolite crystals increased termite mortality significantly above the control treatment. An additional study examining feeding on stained bait (control and 20 m diameter cryolite crystals only) indicated that termites will consume the bait, and that termite mortality from feeding on the bait increases over time.

This is the first report of DTE from workers of R.flavipes and alates of all three species. Quantifiation of DTE was performed on the trimethylsilyl (TMS) derivative, detected by gas chromatography-mass spectrometry. Female alates of all the three species contained similar amounts of DTE (189-262 pg/alate), with males of C.formosanus and R.flavipes having equal amounts, while R. virginicus males had less than 25% of that found in the female. Workers of the three species also contained similar amounts of DTE (95-137 pg/worker). Holding workers for a month in the lab did not cause a significant drop in the DTE levels. The TMS-derivative of four synthetic isomers (Z,Z,E)-, (Z,Z,Z)-, (Z,E,Z)-, and (Z,E,E)-DTE were also separated by GC-MS and compared to the DTE from the three termite species. All termite samples of DTE were found to correspond to the (Z,Z,E)-DTE isomer. Trail-following assays with C.formosanus workers showed only the (Z,Z,E)-DTE isomer to be active at 10 pg/cm. Electroantennographic analysis showed C formosanus and R.flavipes workers to respond to (Z,Z,E)-DTE in a similar dose-dependent manner.

Apart from its spread through transport of infested wood, swarming adults are a major source of new infestations. Under optimal conditions, incipient colonies produced by the primary reproductive pairs grow up to become fully mature colonies. The growth of incipient colonies under laboratory conditions was monitored for seven years. Two peaks of significant increase in the numbers of progeny occurred during the third and seventh year. Foraging, even on a limited scale, had a profound effect on progeny numbers. We also determined the approximate longevity of workers under laboratory conditions.

Sentricon(R) stations were installed along the perimeters of 134 buildings, and inspected monthly thereafter. Sentricon(R) stations with actively foraging termites were immediately baited following label instructions. Two species of Reticulitermes were found at this site: R. hesperus Banks and an undescribed species of Reticulitermes (known as cuticular hydrocarbon phenotype SCA-B). When feasible, auxiliary, or additional, stations were installed adjacent to the active stations to increase the rate of station discovery and to enhance bait consumption. Within two months of installation, 41 % of the buildings had Sentricon (R) stations with signs of subterranean termite activity. This percentage rose to 90% after 6 months and 95% afier one year. Of the 7,327 Sentricon (R) stations initially installed, 12% had subterranean termite activity; 13% of the auxiliary stations had subterranean termite activity. Between 2002 and 2003, 70% fewer Sentricon (R) stations developed new termite activity, likely the result of baiting. After March 2004, very few Sentricon stations became active. These results strongly suggest that the baiting program utilizing the Sentricon (R) Termite Colony Elimination System had a significant impact on both species of Reticulitermes in the subterranean termite community at this site.

Because of these habits they are potentially important at the Idaho National Laboratory (INL) where they may tunnel into and disturb buried waste. Ants are very important components of the desert ecosystem based on their distribution, habitat preferences, food habits, and relative abundance. For these reasons the ant taxa present at the INL were investigated. A cursory survey of the ants at the site was published in 1971 which reported 22 species. A more thorough examination was needed. Our research in the northeastern portion of the Snake River Plain at the INL from 1986 to 1996 produced thousands of ant collections, of which 1,115 (mostly nest series) are used in this manuscript. These collections contained 46 species in 19 genera from three subfamilies. This more than doubles the number of the species previously reported from the INL. Of the ant species found, 18 (39 %) are considered rare on the site, 12 (26 %) are present but not common, 11 (24 %) arc common, and only five (11 %) are found to be abundant. All but three ant genera known for the state of Idaho can be found at the INL. Additionally, four species collected during this research are reported from Idaho for the first time: Liometopum luctuosum, Formica gynocrates, Formica spatulata, and Myrmica sp. Formicoxenus diversipilosus was only found within the nests of the Formica rufa group, Formica planipilis and Formica subnitens. These represent new host records for the species. Formicoxenus hirticornis was found nesting with the thatch ants: Formica planipilis, Formica ciliata, Formica laeviceps, and Formica subnitens, all of which represent new host records for this species. The goal of this investigation is to provide a more thorough survey of the INL ant fauna for both biodiversity and waste management purposes. The objectives were: 1) to produce an updated checklist of the INL ants, 2) to summarize the pertinent published information and literature on the INL ants, and 3) to present keys, distribution maps, illustrations, and ecological information on each taxon. This information should allow for the identification of ants encountered at the site and be of use to ecologists and other scientists working at the site. Much new information concerning the biology, ecology, and natural history of many of the species found on INL is presented. The literature on the ants of the INL is summarized. This work paves the way for more detailed ecological studies of the INL ant fauna. C1 Albertson Coll Idaho, Orma J Smith Museum Nat Hist, Caldwell, ID 83844 USA.

Soils were unamended or amended with either unlabeled 2,4-D or UL(ring) C-13-2,4-D. Degradation of 2,4-D was complete after 17 days, whereas little removal (11 +/- 3%) was observed in the sterile controls. Terminal restriction fragment length polymorphism (TRFLP) on soil DNA after 17 days indicated a consistent increase in the relative abundance of one fragment (217 bp in Hae III digests) in soils spiked with 2,4-D (both unlabeled and labeled samples) compared to the unamended soils. DNA extracts from labeled and unlabeled 2,4-D amended soils were subject to ultracentrifugation, fractionation of centrifuged samples, followed by TRFLP on each fraction. TRFLP profiles from ultracentrifugation fractions illustrated that the same fragment experienced an increase in buoyant density (BD) in samples spiked with C-13-labeled 2,4-D. This increase in DNA BD indicates the organisms represented by this fragment were responsible for uptake and degradation of the herbicide. 16S rRNA sequencing of the heavy, C-13-enriched fraction suggests the organisms belong to the beta subdivision of Proteobacteria. Herein, SIP facilitated the identification of unique organisms degrading 2,4-D in soil without the need for isolation and provided more direct evidence for a functional role of these organisms than would have been possible with the molecular-based methods alone.

Transient unsaturated horizontal column experiments were conducted to assess processes affecting soil NO3 transport. Duplicate tests were conducted on four soils having different physicochemical and mineralogical properties. In each test, a 200 mg/L NO3--nitrogen (NO3--N) solution was applied at the inlet of the relatively dry soil 0.5 columns, and the value of sorptivity kept constant at 0.0073 cm/sec. Comparison of corresponding soil water content and soil solution NO3 -N concentration profiles from the column tests clearly indicated anion exclusion to be an important process impacting NO3 mobility under unsaturated flow conditions. Evidence of anion exclusion for all four soils included soil solution NO3- -N concentrations near the inlet that were 13% to 21% less than the concentration (200 mg/L NO3- -N) injected at the inlet. Further evidence of anion exclusion included peak soil solution NO3--N concentrations up to twice the injected concentration near the wetting front for three of the four soils. The fourth soil, possibly because of a combination of dispersion processes, low pH, and the mixture of clay minerals present, behaved somewhat differently than the other soils by having a peak soil solution NO3--N concentration above 200 mg/L located approximately halfway between the column inlet and wetting front. Overall, this research indicated that anion exclusion can be a key process affecting NO3 mobility in a variety of soil environments. C1 USDA ARS, Soil Drainage Res Unit, Columbus, OH 43210 USA.

The objective of this study was to observe the variation in the predicted distribution of atrazine in the soil profile as the coefficient of distribution (K-d) was varied in one or more soil horizons using the PRZM-2 model. The goal was to identify if more attention should be devoted to understanding the atrazine-soil sorption issues better, or whether discrepancies in field data and model output are explained by the difficulties in assessing the preferential transport of atrazine. The PRZM-2 predicted atrazine distribution was compared with measured values for no-till (NT) and conventional-till (CT) corn plots. Results indicate that reducing K-d by 70% in NT plots reduced the predicted atrazine recovery in Horizon 1 (0-10 cm) by 31%, 34%, and 87% for simulations performed 2, 4, and 8 weeks after application (WAA). Reducing Kd in only the upper soil horizon improved predictions for the upper horizon but overpredicted atrazine concentrations in the second horizon. Reducing Kd throughout the profile reduced predicted atrazine concentrations in the upper horizon and increased predicted concentrations in lower horizons. Improvement in the correlation between predicted and measured atrazine concentrations was greatest for NT plots; however, discrepancies between predicted and measured data still exist and may be due to improper characterization of the atrazine degradation or dissipation parameters. These results suggest that although preferential flow appears to influence atrazine distribution, it may not be the only process influencing our ability to model atrazine fate and transport. Future research on atrazine degradation and dissipation under field conditions seems to be necessary to simulate atrazine fate and transport under preferential flow conditions.

TI Soil water measurement comparisons between semi-permanent and portable capacitance probes SO SOIL SCIENCE SOCIETY OF AMERICA JOURNAL LA English DT Article ID CALIBRATION; DYNAMICS; CORN AB The objectives of this study were to compare and characterize the soil water measurement responses using the EnviroSCAN semi permanent multisensor capacitance probes (MCP) and the Diviner 2000 (D2k) portable capacitance probe. Both probes are manufactured by Sentek Pty. Ltd., Stepney, South Australia. Comparative soil water measurements were made using the portable D2k and the MCP probes at three field sites where 48 poly- vinylchloride (PVC) access tubes were previously installed and being used to near-continuously monitor soil water content at four or more depths. The D2k and MCP soil water sensing data were highly correlated values (R-2 > 0.98), but the D2k water contents averaged about 5% more than the corresponding MCP values. As a result of this high correlation we were able to, g transform the D2k readings so that the two probes gave essentially the same water content values when measured as the same time and position.

TI Improved analysis of heat pulse signals for soil water flux determination SO SOIL SCIENCE SOCIETY OF AMERICA JOURNAL LA English DT Article ID FLOW AB Soil water flux (J) can be estimated from the velocity (V) of pulse of heat introduced into the soil. Here we consider a method in which V is measured with a three-probe sensor. The center probe heats the soil, and the outer probes measure temperature increases downstream (T-d) and upstream (T-u) from the heater. An equation was recently proposed for approximating J from the ratio T-d/T-u. In this note we show that the accuracy of this equation can be improved by adding a term to correct for the time dependence of T-d/T-u. This term is simple to evaluate and requires no additional measurements. Example calculations (three cases) are used to evaluate improvement in accuracy. When T-d/T-u is measurred at a time of 45 s, relative errors in flux estimates are reduced from 10.5, 2.6, and - 10.5% to 0.23, 0.06, and -0.23%, respectively, by using the correction term.

These factors may contribute to management protocols that enhance soil organic matter accumulation in hot climates, which have characteristically high oxidation rates. The purpose of this experiment was to determine O-2 effects on soil polyphenol oxidase (PPO), peroxidase (PO), water-soluble polyphenolics (WEP), arginine ammonification (ARG), and water-extractable C (WEC). Cowpea (Vigna unguiculata L.) and sorghum [Sorghum bicolor (L.) Moench] residues in soil were incubated with headspace O-2 concentrations of 0.5, 10, or 21% (ambient) for up to 110 d. The PPO and PO were negatively related to WEP and WEC, mostly at 10 and 21% (P < 0.05). The WEP and WEC were significantly (P < 0.05) and negatively related to O-2 concentration. The WEP ranged from 0.5 mg kg(-1) soil at 0.5% Oz to near 0 at 10 and 21% O-2. The WC ranged from about 350 mg C kg(-1) soil at 0.5% O-2 to < 25 mg C kg(-1) soil at 10 and 21% O-2. The ARG rates were also negatively related to O-2 level with cowpea, but not as strongly as with sorghum. The ARG and WEC were negatively correlated. The ARG ranged from 6 mg N kg(-1) soil at 0.5% Oz to < 0.5 mg N kg(-1) soil at 21% O-2 through 110 d. The WEC and WEP varied independently during incubation. Our results suggest that soil organic C accumulation may be stimulated by (i) using cover crops with higher polyphenolic content, which could slow C mineralization, and (ii) restricting soil O-2 availability via reduced tillage.

We assessed crop sequence and tillage effects on SOC dynamics and storage using natural (13)C abundance of corn (Zea mays L.) and soybean [Glycine max (L.), Merr.]. Treatments consisted of tillage: moldboard plow (MP), chisel plow (Cl?), and no-tillage (NT); and crop sequence: continuous corn (CC), continuous soybean (SS), and alternating corn-soybean (CS). Soil samples were collected after 14 yr in each treatment and in fallow alley-ways and were analyzed for SOC, delta(13)C, bulk density, and pH. Tillage by crop sequence interactions occurred as treatments with MP and SS as well as fallow averaged 135 Mg SOC ha(-1) (0- to 45-cm depth), while CP treatments with corn (CC and CS) and NT with CC averaged 164 Mg SOC ha(-1). Crop sequence effects on SOC (0- to 45-cm depth) occurred when tillage was reduced with CP and NT averaging 15% greater SOC in CC than SS. In addition to less C inputs than CC, SS accelerated rates of SOC decomposition. Tillage effects on SOC were greatest in CC where CP had 26% and NT 20% more SOC than MP, whereas SOC in SS was similar across tillage treatments. Up to 33% of the greater SOC under CC for CP and NT, compared with MP, occurred below tillage operating depths. Substantial losses of SOC were estimated (1.6 Mg SOC ha(-1) yr(-1)) despite lowering SOC decay rates with reduced tillage and high levels of C inputs with CC.

Our hypothesis was that decomposition is a function of biochemical composition when all other variables are constant (e.g., particle size, temperature and moisture). Recognizing the challenges of reconciling laboratory and field studies, this study examined the decomposition dynamics of five selected crops with varying composition under controlled temperature and moisture regimes. Residue materials were partitioned into leaf, stem, and root organs to give a clearer indication of compositional control on decomposition. Plant quality varied among species (alfalfa [Medicago sativa L.], corn [Zea mays L.], cuphea [Cuphea viscosissima Jacq. " Cuphea lanceolata WT Aiton], soybean [Glycine max (L.) Merr.] and switchgrass [Panicum virgatum L.]). A two-component litter decomposition model was used to describe decomposition observed during 498 d. Stepwise multivariate regression indicated initial N concentration, starch, total lignin, and acid-insoluble ash (AI ash) were the four best predictors (r(2) = 0.83) of the rate of active component decomposition (k(a)); however, initial composition poorly predicted the rate of passive decomposition (k(p)). The best four-component model (r(2) = 0.43) identified by stepwise multiple regression for k(p) included AI ash, hemicellulose, N concentration, and C/N ratio. Rate constants are a function of the incubation period, thus making direct comparison among separate experiments difficult. Chemical recalcitrance appears to slow root decomposition; such chemical recalcitrance to decay may partially explain why roots have been found to contribute more C to the SOC pool than surface residues.

TI Tillage requirements for integrating winter-annual grazing in cotton production: Plant water status and productivity SO SOIL SCIENCE SOCIETY OF AMERICA JOURNAL LA English DT Article ID CONSERVATION TILLAGE; CROPPING SYSTEMS; ORGANIC-MATTER; SOIL; GROWTH; COVER AB Integrating livestock with cotton (Gossypium hirsucum L.) offers profitable alternatives for producers in the southeastern USA, but could result in soil water depletion and soil compaction. We conducted a 3-yr field study on a Dothan loamy sand (fine-loamy, kaolinitic, thermic Plinthic Kandiudult) in southern Alabama to develop a conservation tillage system for integrating cotton with winter-annual grazing of stocker cattle under rainfed 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 mutifiorum L.). Tillage systems included moldboard and chisel plowing and combinations of noninversion deep tillage (none, in-row subsoil, or paratill) with or without disking. We evaluated forage dry matter, N concentration, average daily gain, net returns from grazing, soil water content, and cotton leaf stomatal conductance, plant populations, and yield. Net returns from winter-annual grazing were between US$185 to US$200 ha(-1) yr(-1). Soil water content was reduced by 15% with conventional tillage or deep tillage, suggesting that cotton rooting was increased by these systems. Oat increased cotton stands by 25% and seed-cotton yields by 7% compared with ryegrass. Strict no-till resulted in the lowest yields-30% less than the overall mean (3.69 Mg ha(-1)). Noninversion deep tillage in no-till (especially paratill) following oat was the best tillage system combination (3.97 Mg ha(-1)) but deep tillage did not increase cotton yields with conventional tillage. Integrating winter-annual grazing can be achieved using noninversion deep tillage following oat in a conservation tillage system, providing producers extra income while protecting the soil resource.

TI Digitally mapping gypsic and natric soil areas using Landsat ETM data SO SOIL SCIENCE SOCIETY OF AMERICA JOURNAL LA English DT Article ID SALT-AFFECTED SOILS AB Mapping salt-affected soils in remote rangelands is challenging. We used Landsat 7 ETM data to facilitate digital mapping of gypsic and natric soil areas in the upper Colorado River drainage. Optimum index factor band combinations were used to explore the scene. Normalized difference ratio models and threshold values were developed by comparing spectral signatures with gypsic and natric soil areas verified in the field. Gypsic soil areas were mapped using the normalized difference ratio of Bands 5 and 7 with a threshold > 0.11, probably related to the spectral reflectance of gypsum within a few centimeters of the surface. All sites predicted to be gypsic soil areas were determined to be gypsic by field assessment, and 87% of the field-observed gypsic soil areas were correctly predicted. Natric soil areas were mapped using the normalized difference ratio of Bands 5 and 4 with a threshold > 0.19, possibly related to the co-occurrence of Fe-bearing minerals with natric soil areas. Most of the sites predicted to be natric were determined in the field to be natric (82%); but only half of the field-observed natric areas were correctly predicted, indicating that natric soils are harder to detect spectrally than gypsic soils. While the gypsic model may be transferred to other areas, particularly in the arid Colorado Plateau, transfer of natric models would be difficult. Normalized difference ratio models can be developed for other digital soil mapping areas where land surface features produce differences in Landsat spectral band reflectances.

Concentrations of C and N in light- and heavy fractions of bulk soils and aggregates in 0-20 cm were determined to evaluate the role of aggregation in SOC sequestration under conventional tillage (CT), no-till (NT), and forest treatments. Light- and heavy fractions of SOC were separated using 1.85 g mL(-1) sodium polytungstate solution. Soils under forest and NT preserved, respectively, 167% and 94% more light fraction than those under CT. The mass of light fraction decreased with an increase in soil depth, but significantly increased with an increase in aggregate size. C concentrations of light fraction in all aggregate classes were significantly higher under NT and forest than under CT. C concentrations in heavy fraction averaged 20, 10, and 8 g kg(-1) under forest, NT, and CT, respectively. Of the total SOC pool, heavy fraction C accounted for 76% in CT soils and 63% in forest and NT soils. These data suggest that there is a greater protection of SOC by aggregates in the light fraction of minimally disturbed soils than that of disturbed soil, and the SOC loss following conversion from forest to agriculture is attributed to reduction in C concentrations in both heavy and light fractions. In contrast, the SOC gain upon conversion from CT to NT is primarily attributed to an increase in C concentration in the light fraction. (c) 2006 Elsevier B.V. All rights reserved.

TI Soil hydraulic properties influenced by corn stover removal from no-till corn in Ohio SO SOIL & TILLAGE RESEARCH LA English DT Article DE no-till; corn stover removal; saturated hydraulic conductivity; earthworm middens; bulk density; soil water retention; air permeability ID PHYSICAL-PROPERTIES; RESIDUE MANAGEMENT; WATER INFILTRATION; CROP RESIDUES; CONDUCTIVITY; SURFACE; MACROPOROSITY; EARTHWORMS; PERMEABILITY; DYNAMICS AB Corn (Zea mays L.) stover removal for biofuel production and other uses may alter soil hydraulic properties, but site-specific information needed to determine the threshold levels of removal for the U.S. Corn Belt region is limited. This study quantified impacts of systematic removal of corn stover on soil hydraulic parameters after I year of stover management under no-till (NT) systems. These measurements were made on three soils in Ohio including Rayne silt loam (fine-loamy, mixed, active, mesic Typic Hapludult) at Coshocton, Hoytville clay loam (fine, illitic, mesic Mollic Epiaqualfs) at Hoytville, and Celina silt loam (fine, mixed, active, mesic Aquic Hapludalfs) at South Charleston. Interrelationships among soil properties and saturated hydraulic conductivity (K-sat) predictions were also assessed. Earthworm middens, K-sat, bulk density (rho(b)), soil water retention (SWR), pore-size distribution, and air permeability (k(a)) were determined for six stover treatments. Stover treatments consisted of removing 0 (T100), 25 (T75), 50 (T50), 75 (T25), 100 (T0) and adding 100 (T200)% of corn stover corresponding to 0, 1.25, 2.50, 3.75, 5.00, and 10.00 Mg ha(-1) of stover, respectively. Stover removal reduced the number of middens, K-sat, SWR, and k(a), and increased rho(b) at all sites (P < 0.01). Compared to normal stover treatment (T100), complete stover removal (T0) reduced earthworm middens 6-fold at Coshocton and about 14-fold at Hoytville and Charleston. Geometric mean K-sat decreased from 3.1 to 0.1 mm h(-1) at Coshocton, 4.2 to 0.3 mm h(-1) at Hoytville, and 4.2 to 0.6 mm h(-1) at Charleston while soil rho(b) increased about 12% in the 0-10-cm depth at Coshocton and Hoytville from T100 to T0. The SWR for T0 was about 70% of that for T100 and 58% of that for T200 at 0 to -6 kPa suctions across sites. The log k(a) for T200, T100, and T75 significantly exceeded that under T50, T25, and T0 at Coshocton and Charleston. Differences in the number of middens, rho(b), SWR, K-sat, and k(a) between T100 and T200 were not generally significant although the T200 retained slightly more water for the 0 to -100 kPa at Charleston and had higher ka at Hoytville compared to T100. Measured parameters were strongly correlated, and k(a) was a strong K-sat predictor. Stover harvesting induces rapid changes in soil hydraulic properties and earthworm activity, but further monitoring is needed to ascertain the threshold levels of stover removal for soil-specific conditions.

TI Influence of tillage and plant residue management on respiration of a Florida Everglades Histosol SO SOIL & TILLAGE RESEARCH LA English DT Article DE histosol; soil respiration; tillage; residue management ID CARBON-DIOXIDE FLUX; SOIL CO2 EFFLUX; CHAMBER; BIASES AB Subsidence of drained, high organic matter Histosols in the Everglades Agricultural Area (EAA) is a concern for the sustainability of crop production in southern Florida. Histosol subsidence is primarily due to oxidation of organic matter by aerobic microorganisms, but far less is known about the influence of agricultural practices. The use of shallow tillage, as opposed to deep tillage, combined with proper plant residue management, may help to reduce the present rate of subsidence and Soil CO2 emissions. The present study was conducted on a Lauderhill soil (euic, hyperthermic, Lithic Haplosaprist) previously cropped in sugarcane (Saccharum spp.). The objectives were to (1) determine the effects of tillage depth on short-term CO2 losses in a herbicide-killed weedy residue covered field and another field kept fallow without residue cover, and (2) compare soil respiration measurements made with two different dynamic closed-system portable chamber techniques. Four tillage practices common to the EAA were used to produce soil disturbance ranging in depth from approximately 20 to 300 mm. These practices included switch plowing, disk harrowing, and single and multiple tine cultivation. Twenty-four hours after tillage, cumulative CO2 loss from the deepest tillage treatment (switch plow; 300 mm deep) was as much as 33 times greater than that from the no-till (control) treatment. Cumulative CO2 loss following intermediate tillage (disk harrow; 78-145 mm deep) was as much as 2.3-fold greater than the no-till treatment, but shallower tillage (tine cultivation; 20-41 mm deep) was generally not different. Short-term tillage-induced CO2 loss was primarily related to soil moisture content and soil porosity. Soil respiration measurements made with the two chamber techniques agreed well with each other except for the deepest tillage treatment, where the larger chamber measured CO2 flux that was approximately 10 times greater than for the smaller chamber. Results indicate that minimum or no-tillage may reduce short-term tillage-induced CO2 emissions on organic soils, thus minimizing soil subsidence. (c) 2006 Published by Elsevier B.V.

Thus, the objective of this research was to develop breeding objectives for Angus and Charolais terminal sires to be used in breeding Afrikaner. Bonsmara, and Nguni cows. An aggregated simulation model that is reliant on user inputs for the phenotypic characterization of the germplasm and economic characterization of the production environment was developed. Relative economic values were calculated by approximating partial derivatives of simulated profit with respect to economically relevant traits. Correlations among the breeding objectives calculated from simulations of Angus and Charolais bulls bred to Afrikaner, Bonsmara and Nguni cows were consistently > 0.9. Thus, an average index could be used for all six scenarios with little loss of selection efficiency. On average, relative emphasis given to breeding values for survival. direct weaning weight, postweaning daily gain, postweaning daily feed intake, dressing percent, and fat depth were 3 1.1, 31.0, 17.3, 1.4, 19.1, 0.2%, respectively. These breeding objectives may be viewed as all appropriate step in the evolution of multi-trait selection to facilitate poverty alleviation among cattle producers in the emerging sector through wealth creation resulting from their production of calves for industrial feeding.

Home ranges of Coachwhips contained more oak savanna macrohabitat than early-successional pine plantation or forested seep, based on the availability of these three macrohabitats in the study area. Likewise, within their individual home ranges, Coachwhips used oak savanna more than the other two macrohabitats, based on availability. An analysis of microhabitat use revealed that, relative to random sites within their home range, Coachwhips were found at sites with fewer pine trees and more herbaceous vegetation taller than 30 cm. Results of the two analyses, macrohabitat and microhabitat, were consistent: oak savannas contained relatively few pine trees but much herbaceous vegetation taller than 30 cm. Coachwhips made frequent long-distance moves, which resulted in large home ranges. Core activity areas, however, were small. These core activity areas were always within the oak savanna macrohabitat. Long movements, large home ranges, and small core activity areas likely were a result of the preferred oak savanna macrohabitat being patchily distributed in the landscape.

TI Observations of Speyeria diana (Diana fritillary) utilizing forested areas in North Carolina that have been mechanically thinned and burned SO SOUTHEASTERN NATURALIST LA English DT Article AB Speyeria diana (Diana fritillary) is a forest dwelling butterfly that has been eradicated from portions of its native habitat in North Carolina. This loss has been attributed to habitat destruction and pesticide use, resulting in its status as a species of special concern. During the spring and summer of 2003 and 2004, we conducted butterfly surveys on forested 10-ha plots in the southern Appalachians of North Carolina in which various forest management practices had been applied. During one survey (June 2004), we observed male Diana fritillary butterflies feeding on flowering Oxydendrum arboretum (sourwood) within plots that had been mechanically thinned and burned. These plots also had the greatest herbaceous plant cover. Our observations suggest that some forest management related disturbances, resulting in increased herbaceous plant cover, may help in conserving this species.

Because refuges of forest-dwelling rodents are often associated with woody debris, we examined refuge use by 37 radio-collared Peromyscus gossypinus (cotton mice) in experimental plots with different levels of woody debris. Treatment plots had six times (approximate to 60 m(3)/ha) the volume of woody debris as control plots (approximate to 10 m(3)/ha). Of 247 refuges, 159 were in rotting stumps (64%), 32 were in root boles (13%), 19 were in brush piles (8%), and 16 were in logs (6%); 10 refuges could not be identified. Stumps were the most common refuge type in both treatments, but the distribution of refuge types was significantly different between treatment and control plots. Root boles and brush piles were used more on treatment plots than on control plots, and logs were used more on control plots than on treatment plots. Refuge type and vegetation cover were the best predictors of refuge use by cotton mice; root bole refuges and refuges with less vegetation cover received greater-than-expected use by mice. Abundant refuges, particularly root boles, may improve habitat quality for cotton mice in southeastern pine forests. C1 Univ Nebraska, Sch Biol Sci, Lincoln, NE 68588 USA.

Light-trap data indicated that Copris minutus occurred primarily in the winter and spring, Ateuchus histeroides in the spring and summer, and Onthophagus gazella in the summer and fall. One of the species, O. gazella, is a foreign introduction, and comparative laboratory food procurement experiments revealed the superior ability of this species to obtain and remove dung from the soil surface. A confrontation experiment also demonstrated the behavioral dominance of O. gazella. A food-choice experiment indicated a more restricted diet for O. gazella than for the other two species. Implications for the future prospects of the two native species are discussed. C1 USDA ARS, So Grain Insects Res Lab, Tifton, GA 31793 USA.

We examined several possible dispersal avenues for the plant. We tested germination of seeds exposed to various treatments, including passage through Ictalurus punctatus (Channel Catfish) guts, and conducted other tests and observations to infer seed-dispersal pathways. Channel Catfish consumed swamp privet drupes and defecated viable seeds, confirming that they are seed dispersers. Bombycilla cedrorum (Cedar Waxwings) ate the carbohydrate-rich drupes, and we predict that they disperse the seeds. We also inferred passive seed dispersal by water. Diverse dispersal pathways may allow for effective seed dispersal under a wide range of environmental conditions. Growing in wetlands and riparian areas, the plant experiences extreme annual variation in hydrologic conditions, which should influence the importance of the various dispersal pathways among years.

Twenty-four 8-week old pigs allotted in equal numbers were administered ACTH, dexamethasone or saline, and blood samples were collected every 15 min via an indwelling jugular catheter for 1 h prior to and 5 h following treatment. Total plasma cortisol increased in ACTH-treated pigs and decreased in dexamethasone-treated pigs within 0.25 and 0.5 h, respectively. In contrast, pCBG concentration was altered in an inverse fashion subsequent to the changes exhibited in total cortisol. FCI reflected the changes observed in total cortisol. These results further document the negative relationship that exists between circulating concentrations of plasma cortisol and pCBG, and illustrate that this association exists under conditions of acute stress in the pig.

A historical overview of the taxonomic concepts starting with the monograph of Raper & Fennell (1965) is given. A list of taxa described since 2000 is provided. Physiological characters, particularly growth rates and the production of extrolites, often show differences that reflect phylogenetic species boundaries and greater emphasis should be placed on extrolite profiles and growth characteristics in species descriptions. Multilocus sequence-based phylogenetic analyses have emerged as the primary tool for inferring phylogenetic species boundaries and relationships within subgenera and sections. A four locus DNA sequence study covering all major lineages in Aspergillus using genealogical concordance theory resulted in a species recognition system that agrees in part with phenotypic studies and reveals the presence of many undescribed species not resolved by phenotype, The use of as much data from as many sources as possible in making taxonomic decisions is advocated. For species identification, DNA barcoding uses a short genetic marker in an organism"s DNA to quickly and easily identify it to a particular species. Partial cytochrome oxidase subunit 1 sequences, which are used for barcoding animal species, were found to have limited value for species identification among black aspergilli. The various possibilities are discussed and at present partial beta-tubulin or calmodulin are the most promising loci for Aspergillus identification. For characterising Aspergillus species one application would be to produce a multilocus phylogeny, with the goal of having a firm understanding of the evolutionary relationships among species across the entire genus. DNA chip technologies are discussed as possibilities for an accurate multilocus barcoding tool for the genus Aspergillus. C1 [Geiser, D.

The availability of genomes from several species of the genus Aspergillus allows us for the first time to examine the demarcation of fungal species at the whole-genome level. Here, we examine four case studies, two of which involve intraspecific comparisons, whereas the other two deal with interspecific genomic comparisons between closely related species. These four comparisons reveal significant variation in the nature of species boundaries across Aspergillus. For example, comparisons between A. fumigatus and Neosartorya fischeri (the teleomorph of A. fischerianus) and between A. oryzae and A. flavus suggest that measures of sequence similarity and species-specific genes are significantly higher for the A. fumigatus - N. fischeri pair. Importantly, the values obtained from the comparison between A. oryzae and A. flavus are remarkably similar to those obtained from an intra-specific comparison of A. fumigatus strains, giving support to the proposal that A. oryzae represents a distinct ecotype of A. flavus and not a distinct species. We argue that genomic data can aid Aspergillus taxonomy by serving as a source of novel and unprecedented amounts of comparative data, as a resource for the development of additional diagnostic tools, and finally as a knowledge database about the biological differences between strains and species.

Sequencing of house-hold genes has also been used in Aspergillus taxonomy and phylogeny, while extrolites and physiological features have been used less frequently. Three independent ways of classifying and identifying aspergilli appear to be applicable: Morphology combined with physiology and nutritional features, secondary metabolite profiling and DNA sequencing. These three ways of identifying Aspergillus species often point to the same species. This consensus approach can be used initially, but if consensus is achieved it is recommended to combine at least two of these independent ways of characterising aspergilli in a polyphasic taxonomy. The chemical combination of secondary metabolites and DNA sequence features has not been explored in taxonomy yet, however. Examples of these different taxonomic approaches will be given for Aspergillus section Nigri. C1 [Frisvad, J. C.; Larsen, T.

Aspergillus species are used in the fermentation industry, but they are also responsible of various plant and food secondary rot, with the consequence of possible accumulation of mycotoxins. The aflatoxin producing A. flavus and A. parasiticus, and ochratoxinogenic A. niger, A. ochraceus and A. carbonarius species are frequently encountered in agricultural products. Studies on the biodiversity of toxigenic Aspergillus species is useful to clarify molecular, ecological and biochemical characteristics of the different species in relation to their different adaptation to environmental and geographical conditions, and to their potential toxigenicity. Here we analyzed the biodiversity of ochratoxin producing species occurring on two important crops: grapes and coffee, and the genetic diversity of A. flavus populations occurring in agricultural fields. Altogether nine different black Aspergillus species can be found on grapes which are often difficult to identify with classical methods. The polyphasic approach used in our studies led to the identification of three new species occurring on grapes: A. brasiliensis, A. ibericus, and A. uvarum. Similar studies on the Aspergillus species occurring on coffee beans have evidenced in the last five years that A. carbonarius is an important source of ochratoxin A in coffee. Four new species within the black aspergilli were also identified in coffee beans: A. scierotioniger, A. lacticoffeatus, A. sclerotiicarbonarius, and A. aculeatinus. The genetic diversity within A. flavus populations has been widely studied in relation to their potential aflatoxigenicity and morphological variants L- and S-strains. Within A. flavus and other Aspergillus species capable of aflatoxin production, considerable diversity is found. We summarise the main recent achievements in the diversity of the aflatoxin gene cluster in A. flavus populations, A. parasiticus and the non-toxigenic A. oryzae. Studies are needed in order to characterise the aflatoxin biosynthetic genes in the new related taxa A. minisclerotigenes and A. arachidicola.

The species concept is based on phenotypic (morphology and extrolite profiles) and molecular (beta-tubulin and calmodulin gene sequences) characters in a polyphasic approach. Four new taxa are proposed: N. australensis N. ferenczii, N. papuaensis and N. warcupii. All newly described and accepted species are illustrated. The section consists of 33 taxa: 10 strictly anamorphic Aspergillus species and 23 Neosartorya species. Four other Neosartorya species described previously were not available for this monograph, and consequently are relegated to the category of doubtful species. C1 [Samson, R.

Bacteria from individual guts of larvae, pupae and adults were cultured and DNA was extracted from samples of pooled larval guts. Analysis of 16S rRNA gene sequences amplified directly from the gut community suggests that the gut bacterial communities associated with I. pini are relatively simple, compared to many other systems. Six bacterial genera from four classes were detected by culturing gut bacteria from larvae, pupae and adults. Two genera, Pantoea and Stenotrophomonas (gamma-Proteobacteria) were found in all life stages of I. pini, consistently in larvae and adults, and less commonly in pupae. Sequences that affiliate with the Enterobactereaceae of the gamma-Proteobacteria were found in 95% of the clones sampled. The Enterobactereaceae genera, Pantoea and Erwinia, accounted for 88% of all clone sequences. These results are consistent with previous work indicating that another bark beetle, the southern pine beetle, Dendroctonus frontalis Zimmerman, also has a relatively simple gut flora, compared with wood colonizing insects such as wood borers and termites. The composition and abundance of bacteria associated with different life stages of I. pini are possibly associated with specific functions of the gut bacterial communities of larvae, pupae, and adults.

The phosphonate reagents, diethyl methylformylphosphonate dimethylhydrazone and diethyl ethylformyl-2-phosphonate dimethylhydrazone, contained a protected aldehyde group instead of the usual ester group. A homologation cycle entailed condensation of the reagent with the starting aldehyde, followed by removal of the dimethylhydrazone protective group with a biphasic mixture of 1 M HCl and petroleum ether. This robust two-step process worked with aliphatic, alpha,beta-unsaturated and aromatic aldehydes. Isolated yields for the condensation step ranged from 77% to 89%, and yields for the deprotection step ranged from 81% to 96%.

This study identifies the most significant linear difference equations for each gene in a network. A log-time domain interpolation addresses the non-uniform sampling issue typically observed in a time course experimental design. This system model also insures its power stability under the normal condition in the absence of the inhibitor. The statistically significant system model, estimated from time course gene expression measurements during the earlier exposure to 5-hydroxymethylfurfural, reveals known transcriptional regulations as well as potential significant genes involved in detoxification for bioethanol conversion by yeast.

In total, 89 commercial gilts were artificially inseminated and 61 progressed to term and farrowed. All of the resulting piglets were housed and raised identically under standard commercial settings and slaughtered upon reaching market weight. Loin samples were taken from each slaughtered animal and shipped offsite for meat composition analysis. In total, loin samples from 404 animals (242 from offspring of clones and 162 from controls) were analyzed for 58 different parameters generating 14,036 and 9396 data points from offspring of clones and the controls, respectively. Values for controls were used to establish a range for each parameter. Ten percent was then added to the maximum and subtracted from the minimum of the control range, and all results within this range were considered clinically irrelevant. Of the 14,036 data points from the offspring of clones, only three points were found outside the clinically irrelevant range, two of which were within the range established by the USDA National Nutrient Database for Standard Reference, Release 18, 2005; website: http://www.nal.usda.gov/fnic/foodcomp/search/. The only outlier was the presence of Eicosadienoic acid (C20:2) in one sample which is typically present in minute quantities in pork; no reference data were found regarding this fatty acid in the USDA National Nutrient Database. In conclusion, these data indicated that meat from the offspring of clones was not chemically different than meat from controls and therefore supported the case for the safety of meat from the offspring of clones.

The experiment was conducted separately under different packing densities and water contents to see the effects of the heat sink compounds on the thermal properties at such conditions. High conductivity grease increased the values of thermal conductivity considerably and thus reduces the contact resistance, with increase in bulk density at air-dry conditions, but had virtually no effects on its thermal diffusivity. It however decreased both the thermal conductivity and thermal diffusivity with water content increment. The thermal properties obtained without thermal grease vary considerably from those with the heat sink compounds as water was being applied The variation however reduced also considerably towards saturation.

The mass spectra showed a prominent peak at m/z 4963 in monocytes/macrophages but not in the granulocytes. Subsequent purification and characterization of the m/z 4963 peptide from an avian macrophage cell line HTC, revealed it to be thymosin beta-4 (T beta-4), an actin-modulating peptide. HTC cells when treated with bacterial lipopolysaccharide and peptidoglycan to determine the modulation of T beta-4 gene expression or its secretion, showed no changes.

Results of five different calibration algorithms for bulk density and moisture content determination from microwave measurements indicate that predictions from near-field measurements with microstrip antennas compare well with those derived from far-field measurements with horn/lens antennas. Computation of corresponding standard errors of calibration (SEC) indicates that the accuracy with which each entity can be determined remains within an acceptable range.

The disease was produced experimentally in two goats by the administration of dry Turbina cordata mixed with grain. Clinical signs were observed after the ingestion of 62 and 106g/kg body weight in 28 and 54 days, respectively. The concentration of swainsonine in the plant varied from less than 0.001% to 0.14% (dry weight). Clinical signs of natural and experimental cases included difficulties in standing, ataxia, hypermetria, wide-bascd stance, intention tremors, spastic paresis mainly in the hind legs, nystagmus, abnormal postural reactions, head tilting, and falling. Diffuse vacuolation of neurons, epithelial cells of pancreas, thyroids, and renal tubules were observed on the histology. From the electron microscopy of Purkinje cells the vacuoles represented dilated lysosomes. These findings demonstrated that T cordata causes an acquired glycoprotein lysosomal storage disease. The intoxication occurs at least in an area of 27,000 km(2) causing severe losses in goats, and some farmers report the disease also in cattle. (c) 2006 Elsevier Ltd. All rights reserved.

The phytotoxic components of most agents have not been elucidated, but some phytotoxins and other secondary compounds produced by such microbes may be toxic to mammalian systems. Furthermore, few rigorous assessments have addressed uptake, translocation, metabolism, and persistence of these phytotoxins (some of which have not been identified), or the environmental effects of repeated augmentative applications of these microorganisms on long-term impact, environmental fate, or interactions with other microbial communities. Generally, there is a lack of definitive research on the overall toxicological risk of bioherbicidal microorganisms to the degree achieved or required for synthetic herbicides. This article presents a brief overview of bioherbicides (microorganisms and/or their phytotoxins), with emphasis on the toxicity of certain bioherbicides, and general considerations of risks associated with bioherbicidal use. A subsequent article presents some of our research results and future research directions on efforts to develop the bioherbicidal fungus Myrothecium verrucaria as a safe and efficacious bioherbicide have been published elsewhere.

Because ribose derivatives play critical roles in information storage, energy currency, and photosynthesis, ribose should provide the basis for a toxic analog mechanism. The only known simple ribose-analog toxin, (-)-botryodiplodin, exhibits anticancer, antibacterial, antifungal, phytotoxic, mitogenic, and antifertility activities, and may play a role in plant diseases. Unusual structural properties allow oligomerization of (-)botryodiplodin to pigments and cross-linking agents, which may be responsible for some of its biological activities, but there is no evidence that (-)-botryodiplodin or any other known toxin acts by a ribose-analog mechanism.

TI An instrumentation platform and GPS position latency issues for remote sensing on agricultural aircraft SO TRANSACTIONS OF THE ASABE LA English DT Article DE precision agriculture; site-specific management; thermal imaging; video mapping ID CITRUS TREES; IMAGERY; INDEX; VIDEO; CORN AB To help support and enhance research programs at the Delta States Research Center, Stoneville, Mississippi (USDA-ARS and Mississippi State University cooperating), there has been a need to sense field variables from an easily scheduled remote sensing platform. Agricultural aircraft are widely used for aerial spraying in the mid-southern U.S., so they are also convenient platforms for remote sensing. Research programs are being supported with an eye on providing low-cost imaging tools that can be used by aerial applicators for site-specific management and that include optical and thermal methods for detection of weeds, soil variability, crop stresses, deleterious fishpond constituents, and fire ant mounds. Global Positioning System (GPS) receivers, instrumentation, and pilot controls for use of the remote sensing systems are described, and data and thermal imagery from afield application are illustrated. A novel event triggering device was used to determine positioning accuracy of the GPS receiver that is a component of the Satloc Airstar M3 guidance system. Testing this receiver was a prerequisite to testing two stand-alone GPS units (Garmin 76S and Lowrance Airmap 100) used for position-based camera triggering and image georeferencing. Satloc-derived ground position was found to be within 8 in of actual ground position using the event trigger, so stand-alone GPS units were compared with readings from the Satloc. The Garmin receiver showed a distinct influence of ground speed on position, but the Lowrance unit showed little change in position with changing ground speed. Both stand-alone GPS receivers showed a curious lead in position by as much as 2 s (126 in) over the Satloc, which should be taken into account if using stand-alone GPS receivers for camera triggering or image georeferencing.

TI Finite element analysis of cone penetration in soil for prediction of hardpan location SO TRANSACTIONS OF THE ASABE LA English DT Article DE adaptive meshing; cone penetrometer; finite element; soil-cone interaction; soil hardpan ID COMPACTION; DRAFT AB An accurate determination of soil hardpan location is important for maximum precision tillage performance. Cone penetrometers are often used to locate hardpans in soils. This determination in layered soils is more complex due to the complexity of soil reaction to cone penetration. An axisymmetric finite element (FE) model was developed to simulate cone penetration for the prediction of the hardpan location in a layered Norfolk sandy loam soil. The soil was considered as a non-linear elastic-plastic material, and it was modeled using a Drucker-Prager model with the Hardening option in ABAQUS, a commercially available FE package. ABAQUS/Explicit was used to simulate soil-cone contact pair interaction. The results showed that the FE model captured the penetration resistance trend with two deflection points indicating the start of the hardpan and the peak cone penetration resistance. The FE-predicted results showed the hardpan at a depth of 7.29 cm compared to 11.08 cm from cone penetration tests.

TI A farm-scale test of nitrogen assimilation by vegetated buffer systems receiving swine lagoon effluent by overland flow SO TRANSACTIONS OF THE ASABE LA English DT Article DE animal waste; nitrogen; vegetated buffers; water quality ID FILTER STRIPS; WASTE-WATER; CONSTITUENTS; POLLUTION; REMOVAL; NITRATE; RUNOFF; MANURE; AREAS AB A farm-scale study was conducted from 2000 to 2004 to determine the effectiveness of grass-forest vegetated buffers in assimilating nitrogen (N) from overland flow application of swine lagoon effluent. The rationale for the study was that replicated buffer plot studies had shown that vegetated buffers will effectively assimilate N, but it was not known whether or not they would work at a larger scale. The study was conducted on a commercial farm near Tifton, Georgia. Wastewater was pumped from a single-stage anaerobic lagoon to vegetated buffers composed of grass and mature or newly planted pines. The buffers approximated 60 m in length by 90 m in width. The upper 10 m of each buffer was in grass, while the downslope area was in mature or newly planted pines. Six buffers were instrumented for wastewater application and water quality monitoring. Two buffers received wastewater at a 1X rate (600 kg N ha(-1) year(-1)), two at a 3/4X rate (450 kg N ha(-1) year(-1)), and two served as controls. The wastewater was applied to the 10 m grassed portion of the buffers. Transects of shallow groundwater wells starting at the grass-forest interface and running downslope were used to monitor water quality N. The study showed mixed results concerning N assimilation by the buffers. Upslope land use changes by the producer during the study added significant N inputs to one set of buffers, and they were unable to assimilate sufficient N from both these inputs and the wastewater to protect shallow groundwater quality. In contrast, almost all samplings of shallow groundwater under the buffers receiving N only from the overland flow applied swine lagoon effluent showed nitrate (NO3-N) concentrations 20 and 30 m downslope to be lower than 10 mg L-1 (drinking water standard). On these buffers, NO3-N concentrations in shallow groundwater were near background levels five years after wastewater application commenced. The study indicated that the ratio of buffer area width to wastewater application area width on the landscape should be at least 1:1, and that buffers for protection of water quality should be continuous oil the landscape. It was concluded from the study that buffers call be used at the farm scale to assimilate N from applied wastewater when they are sufficiently wide relative to waste application area, rate, and other N sources at the farm scale.

TI Performance comparison of RF impedance and DC-conductance measurements for single peanut kernel moisture determination SO TRANSACTIONS OF THE ASABE LA English DT Article DE capacitance; conductance; moisture content; peanuts. ID CORN AB Two methods for rapidly determining the moisture content of single peanut kernels (Arachis hypogaea L.), were compared with a standard forced-air oven method to evaluate their performance. One method was based on estimating the moisture content from the measurement of capacitance and phase angle of a parallel-plate capacitor with a single peanut held between the plates. These measurements were made at two frequencies (1.0 and 4.5 MHz). The other method was a DC conductance measurement on a single peanut as it passed between two crushing-roller electrodes. This method is used in a commercial instrument presently available. Moisture content was determined by these two methods and by the standard oven method on 30 individual peanut kernels randomly selected from each of six sample lots with moisture contents ranging from 6% to 16%, wet basis. Moisture content measurements obtained using the capacitance and the conductance methods were in agreement with the standard oven values to an acceptable accuracy for over 80% of the samples tested. A distinct advantage of the capacitance method is that it is nondestructive. C1 USDA ARS, Natl Peanut Res Lab, Dawson, GA 31742 USA. RP Kandala, CVK (reprint author), POB 509, Dawson, GA 31742 USA.

TI A diffuse reflectance measuring instrument to determine peanut pod brightness SO TRANSACTIONS OF THE ASABE LA English DT Article DE detector; discolored; pod brightness; reflectance; Valencia peanuts AB For Valencia peanuts, pod brightness is determined by inspectors during the peanut grading process when peanuts are sold by the grower. Presently, inspectors make visual observation of each peanut pod, from a sample drawn from a bigger lot, and determine the percentage of discolored pods present in the sample. The percent discolored pods is one of ten grade factors that determines the price at which the Valencia peanuts are sold. The visual method seems to be reliable, but it may not be consistent among inspectors nor over time due to the human element involved. An instrument may be more consistent and objective. The design and operation of an optical system for this purpose is described here. A narrow beam of white light was collimated onto the surface of a peanut pod at four consecutive positions spaced at 90 degrees intervals around the circumference of the peanut pod. Diffuse reflectance from the peanut surface was measured at each position using a silicon detector with UV enhanced response. The average of these four values was a good indicator of the pod brightness and was used to detect discolored peanuts. Percent discolored pods determined using this instrument was highly correlated (r(2) = 0.98) with the visual evaluations made by inspectors. C1 USDA ARS, NPRL, Dawson, GA 39842 USA.

TI Uniformity of distribution of anhydrous ammonia into shelled corn in a continuous ammoniator SO TRANSACTIONS OF THE ASABE LA English DT Article DE ammonia; corn; fuel ethanol; kernels ID FERMENTATION AB Cost-effective recovery of non-fermentable, insoluble parts of the corn kernel before fermentation may increase the efficiency of fermentation and lower the overall cost of producing ethanol fuels. Treating whole corn with ammonia gas may weaken the physical structure of the kernel, and improve grinding and separations sufficiently to make fractionation of the non-fermentable components of the kernel cost-effective. The quick and even distribution of a controlled amount of ammonia into a batch of corn is problematic because the absorption of ammonia is rapid and exothermic. A device to continuously and evenly treat 2.3 kg/min (5 lb/min) of corn with ammonia gas (1000 mg N per kg corn) was designed, built, and tested. Ammonia was trapped and recycled within the treatment section of the ammoniator by, feeding continuous streams of buffer solution and air flowing counter-current to the corn through the device. The kernel residence time in the treatment section was approximately 8 min. An assay for the ammonia content of individual corn kernels was developed, and the standard deviation among kernels from samples of ammoniated corn showed that ammonia was much more evenly distributed in the continuous ammoniator than in a bench-scale batch ammoniator.

Further, state air pollution regulatory agencies (SAPRAs) utilize the NAAQS to regulate criteria pollutants emitted by industries by applying the NAAQS as a property-line concentration limit. The primary NAAQS are health-based standards; therefore, an exceedance implies that it is likely that there will be adverse health effects for the public. Prior to and since the inclusion of PM10 and PM2.5 into the EPA's regulation guidelines, numerous journal articles and technical references have been written to discuss the epidemiological effects, trends, regulations, methods of determining PM10 and PM2.5, etc. A common trend among many of these publications is the use of samplers to collect information on PM10 and PM2.5. Often, the sampler data are assumed to be an accurate measure of PM10 and PM2.5. The fact is that issues such as sampler uncertainties, environmental conditions, and characteristics of the material that the sampler is measuring must be incorporated for accurate sampler measurements. The purpose of this article is to provide the background and theory associated with particle size distribution (PSD) characteristics of the material in the air that is being sampled, sampler performance characteristics, the interaction between these two characteristics, and the effect of this interaction on the regulatory process. The results show that if the mass median diameter (MMD) of the PM to which the sampler is exposed is smaller than the cutpoint of the sampler, then under-sampling occurs. If the MMD of the PM is greater than the cutpoint of the sampler, then over-sampling occurs. The information presented in this article will be utilized in a series of articles dealing with the errors associated with particulate matter measurements.

The bridge was constructed by the Georgia Forestry Commission, with guidance from the U.S. Department of Agriculture, Forest Service, Forest Products Laboratory (FPL). Water-borne chromated copper arsenate lumber was used for the deck, instead of the oil-borne preservatives recommended by AASHTO. The bridge was initially monitored by FPL and remained in service from 1994 to 2001 with no maintenance, at which time the bridge was inspected and load tested and the posttensioning bars were restressed. In 2005 the bridge was again inspected and load tested, and the bars were retensioned. The results of the inspection and load tests are presented. The overall condition of the bridge is reported, along with details on the moisture condition, overall deck deflection, and timber strains under load. Details on the loss of posttensioning forces in the bars, and an investigation of the causes of this loss, are presented. C1 [Gentry, T.

In-place stabilization of properly graded aggregate with chloride additives is cost-effective and provides performance and intangible benefits. Similar results are achieved by mixing additives with aggregate during crushing. This 2-year study identifies conditions in which chloride-stabilized roads have a projected life of 10 years or more if properly maintained. The greatest benefits are realized in projects with high aggregate surfacing replacement costs and average daily traffic volumes that exceed 100. Stabilization provides a higher standard of road surface performance by improving ride quality and reducing dust, corrugations (washboarding), and raveling (loose aggregate). Other intangible benefits include reduced sedimentation in streams, reduced aggregate resource depletion, reduced health hazards from dust, and increased road-user safety. This project developed guidelines for chloride stabilization of various aggregate surfacing materials in semiarid to arid environments. Performance and cost-effectiveness of chloride stabilization were measured on 12 projects and monitored for two seasons in four western states; monitoring included construction and maintenance costs, road surface deterioration, traffic, weather conditions, environmental effects, and materials testing. Treated surfaces needed blading after 25,500 vehicles, whereas untreated surfaces needed blading after only 3,200 vehicles. Environmental effects on trees, streams, and roadside soils were insignificant. Many tools were developed to assist in the proper implementation of chloride stabilization of road surface aggregates.

Berry, Jonathan TI Reduced impact logging road issues in tropical forests SO TRANSPORTATION RESEARCH RECORD LA English DT Article AB Road design, construction, and maintenance practices need to be significantly improved in many logging operations being undertaken in tropical forests worldwide. Reduced impact logging is a program designed to achieve more cost-effective and sustainable logging practices through good stand inventories, sound silvicultural practices, less waste and damage in the operations, and replanting where necessary. The program also involves design and construction of improved logging roads. Many roads being constructed and used today are poorly built, poorly drained, and poorly maintained. Resulting impacts include unnecessarily high road costs, inefficient logging operations, and significant negative environmental impacts. Little consideration is given to long-term or full life-cycle costs of the roads. These are not new problems. The objectives of this paper are to identify ongoing common problems and recommend practical solutions, reiterate the need for good basic engineering practices, and highlight some of the negative impacts of poor engineering practices. Key problems that appear to cause unnecessarily high road costs and inefficient logging operations include inadequate road surface drainage, excessively wide roads and roads built under inconsistent design standards, inadequate use of available road surfacing materials, inadequate road maintenance, and poor road location and the subsequent need for road reconstruction. A variety of other road drainage, materials, and erosion control issues also need improving. Social and environmental issues related to roads and their access include colonization and development along the road corridor, illegal logging and subsequent deforestation, bush meat hunting and wildlife depletion, spread of diseases, and other land use changes. Road management and access control are needed along with improved design, construction, and maintenance practices. C1 USDA, Forest Serv, Quincy, CA 95971 USA.

On November 9,2005, the U.S. Department of Agriculture (USDA) Forest Service published a final travel management regulation governing use of OHVs and other motor vehicles on National Forest System lands. The final rule requires individual national forests to designate those roads, trails, and areas open to motor vehicle use. For the USDA Forest Service to designate a road to be open for operation of both highway-legal and non-highway-legal vehicles at the same time (motorized mixed use), an engineering analysis must be performed. When motorized mixed-use designation is proposed for a road, a qualified engineer must determine whether that road can accommodate motorized mixed use, mitigation measures should be implemented before designation, or designation would be inappropriate. The guidelines that will be used by qualified engineers of the USDA Forest Service to analyze low-volume National Forest System roads are described, along with factors to be included in the analysis, possible mitigation measures, and documentation for motorized mixed-use analysis.

TI Determining when to place and remove spring load restrictions on low-volume roads - Three low-cost techniques SO TRANSPORTATION RESEARCH RECORD LA English DT Article AB Damage to low-volume roads in seasonal frost areas can be kept to a minimum by implementing seasonal load restrictions (SLRs). However, not all agencies responsible for road management implement such restrictions, and among those that do, there is no standard technique. Some use qualitative methods, such as observation or dates. Others use quantitative methods, such as measuring or estimating stiffness or subsurface temperature. Loss and recovery of summertime pavement strengths can be directly measured with a falling-weight deflectometer (FWD). Alternatively, mathematical models of varying levels of complexity, using meteorological data, are in existence or are undergoing development for SLR placement. However, initial investment for an FWD can be prohibitive for agencies such as the U.S. Department of Agriculture Forest Service (FS), for which road management is not a primary mission. Similarly, such agencies have limited personnel to conduct detailed calculations required of complex mathematical models. Consequently, easy-to-use, low-cost alternatives are needed. In cooperation with other partnering agencies, FS has recently been evaluating several techniques for determining when to place and remove SLRs. Three methods that appear promising include (a) subsurface instrumentation for temperature and moisture, (b) portable or lightweight FWDs, and (c) the thaw index. Technology-and-development efforts in each of these areas are outlined here; field test programs, observations, and analysis procedures are discussed; and recommendations for implementing each method are provided.

Clarkin, Kim TI Geomorphic, aquatic, and engineering design considerations for low-water crossings SO TRANSPORTATION RESEARCH RECORD LA English DT Article AB A wide variety of low-water stream crossings have been built on low-volume roads across the United States over the past 50 years with the primary objectives of traffic access and cost savings. They are generally a rigid structure in a dynamic stream system, so most have worked to varying degrees from a road use standpoint. Many have required maintenance, repairs, or design modifications to function as they exist today. In addition, most structures have caused problems with regard to stream sediment transport, promoting upstream aggradation or downstream scour and creating barriers or limitations to the passage of aquatic organisms. Three fundamental types of fords both maintain good stream function and provide for traffic use: simple at-grade fords, low-water bridges, and vented fords with a large waterway opening area, preferably with a natural stream channel bottom. Each has a large waterway open area that does not constrict most flow. Ideally the width is at least equal to that of the natural bankfull channel. This paper discusses the problems observed and the requirements for a ford to meet stream function needs, pass sediment appropriately, provide for the passage of fish and other aquatic organisms, and meet engineering design needs. Some fords are designed specifically to function in extreme dynamic conditions, such as in debris torrent or alluvial fan channels, in desert or other "flashy" hydrologic regimes, or where debris jams and overbank flooding are frequent. Fitting the structure to the site requires experience and sound geomorphic, hydraulic, and engineering design. The task should be undertaken with an interdisciplinary team approach.

This paper discusses a commonsense approach, combined with science, to help select the best locations for bridges. Problems associated with bridge location and construction can be alleviated by conducting a proper site investigation, paying attention to geomorphological indicators, and understanding road template design needs and how streams and watersheds function. Channel classification provides a simple framework to help understand the problems that may exist at bridge locations and to help with route locations. An interdisciplinary approach is required to incorporate all the considerations involved in choosing the best bridge location.

Adipose tissue has traditionally been considered a passive storage energy depot that, indeed, does serve as a long-term reservoir for fuel stored as triglyceride. However, laboratory, clinical, and epidemiological studies over the past decade have redefined and greatly expanded our understanding of the physiological role of AT. We now appreciate that AT is an endocrine organ with important roles in maintaining whole-body energy homeostasis and systemic metabolism. This appreciation derives in large part from the identification of multiple AT-secreted factors that modulate central and peripheral processes. These include free fatty acids, which have significant effects on glucose and insulin homeostasis, as well as bioactive peptides termed adipokines. Adipokines act in an autocrine, paracrine, and/or endocrine fashion to promote metabolic homeostasis, and integrate adipose tissue, liver, muscle, and CNS physiology. There are currently more than 50 known adipokines, as well as locally generated hormones and metabolites that, together, affect multiple physiological functions including food intake, glucose homeostasis, lipid metabolism, inflammation, vascular tone, and angiogenesis. Because they affect such diverse and important processes, regulation of adipokine secretion from AT is critically important to regulating systemic metabolism. Notably, increased AT mass (as in obesity) induces characteristic qualitative and quantitative changes in adipose tissue metabolism and adipokine secretion. These changes are now implicated in the development of metabolic syndrome and its progression to more severe obesity-associated pathologies, including type 2 diabetes and cardiovascular disease.

After trees were felled, sound velocity was measured on 4-m logs with the Director HM200. Disks were taken to estimate dry and green wood density; dynamic MOE was estimated as green density x (sound veloeity)(2). Heritability estimates of MOE (across-site h(2)=0.55) were larger than those for total height (0. 15) and diameter at breast height (DBH; 0.29), and similar to those for density (0.59). Negative genetic correlations were found for MOE with height (r(A)=-0.30) and DBH (r(A) =-0.5 1), and were similar to those found for density with height (r(A)= -0.52) and DBH (r(A) =-0.57). The partial correlations of height with MOE and density, while holding DBH constant, were positive, implying that the observed negative correlations between height and the wood properties were a function of the high positive correlation between height and D13H and the strong negative correlations between DBH and the wood properties. Taper [DBH/(height-1.4)] was found to be negatively associated with MOE. Selection for MOE may produce greater gains than selection for density because MOE had a larger coefficient of additive variation (9.6%) than density (5.1%). Conversely, selection for growth may have a more negative impact on MOE than density because of the greater genetic variation associated with MOE. Family mean correlations of the wood quality traits with stem form and crown health were mostly nonsignificant. C1 USDA, US Forest Serv, Forestry Sci Lab, Corvallis, OR 97331 USA.

Using expressed sequence tag sequences, unique transcript sets were assembled in loblolly pine (Pinus taeda L.), white spruce [Picea glauca (Moench) Voss], Douglas-fir [Pseudotsuga menziesii (Mirb.) Franco var. menziesii], and sugi [Cryptomeria japonica (Thunberg ex Linnaeus f.) D. Don]. They were compared with COS sets identified in three model plant species using comparative sequence analysis. Almost half of the single-copy genes in herbaceous species (Arabidopsis and rice) had additional copies and homologs in poplar and conifers. The identified tentative COS sets have many applications in evolutionary genomics studies, phylogenetic analysis, and comparative mapping.

Franco), a shade-intolerant species, and western hemlock (Tsuga heterophylla (Raf.) Sarg.), a shade-tolerant species, to study the temporal pattern of release from suppressive shade. In particular, we sought to determine whether hydraulic architecture or photosynthetic capacity is most important in constraining release. The study was conducted at two sites with mixed stands of 10- to 20-year-old Douglas-fir and western hemlock. At one site, the stand had been thinned allowing release of the understory trees, whereas at the other site, the stand remained unthinned. Douglas-fir had lower height growth (from 1998-2003) and lower relative height growth (height growth from 1998 to 2003/height in 1998) than western hemlock. However, relative height growth of released versus suppressed trees was higher in Douglas-fir (130%) than in western hemlock (65%), indicating that, although absolute height growth was less, Douglas-fir did release from suppression. Release seemed to be constrained initially by a limited photosynthetic capacity in both species. Five years after release, Douglas-fir trees had 14 times the leaf area and 1.5 times the leaf nitrogen concentration (N-area) of suppressed trees. Needles of released western hemlock trees had about twice the maximum assimilation rate (A(max)) at ambient [CO2] as needles of suppressed trees and exhibited no photoinhibition at the highest irradiances. After release, trees increased in leaf area, leaf N concentration and overall photosynthetic capacity. Subsequently, hydraulic architecture appeared to constrain release in Douglas-fir and, to a lesser extent, in western hemlock. Released trees had significantly less negative foliar delta C-13 values than suppressed trees and showed a positive relationship between leaf area:sapwood area ratio (A(L)/A(S)) and delta C-13, suggesting that trees with more leaf area for a given sapwood area experienced a stomatal limitation on carbon gain. Nonetheless, these changes had no significant effects on leaf specific conductivities of suppressed versus released trees of either species, but leaf specific root conductance was significantly lower in released Douglas-fir.

Most monitoring programs, however, do not take full advantage of the potential afforded by molecular genetic markers, which can provide information relevant to both ecological and evolutionary time frames, while costing less and being more sensitive and reliable than traditional monitoring approaches. As several molecular and computational approaches are relatively new, many technical and theoretical issues remain to be resolved. Here, we illustrate how DNA and population genetic data can provide valuable information, often unattainable via other approaches, for monitoring species of management, conservation and ecological interest.

With continued population growth and economic development in this region, the impacts of our mining legacy are proving to be equally important to citizens in our modern society. By one estimate, 500,000 abandoned mine sites are scattered across the western landscape, largely on public land ( state and federal), affecting 16,000 miles of streams. Federal land management agencies such as the U. S. Department of Agriculture Forest Service and U. S. Department of Interior Bureau of Land Management are able to use their authorities under the Comprehensive Environmental Response, Compensation, and Liability Act to respond to the release of hazardous substances from these abandoned mines. Although human health is a primary consideration in prioritizing site response, environmental issues such as the impact on terrestrial species, water quality, or aquatic species also may influence site response priorities. Challenges faced in reducing or preventing further release of hazardous substances at historic mines sites include limited available funds, difficult access, changing public land uses, and increasing populations in nearby areas.

Mercury contamination from these mines has migrated into a variety of different media in varying forms. Cleanups and mitigation projects have been undertaken by various agencies and private entities at a number of these mines, although many remain to be addressed. Although each cleanup has similar objectives, such as source control, the methods employed in each area of the site may differ. By having an understanding of mercury and its effects and assessing different methods used at mercury-mine cleanups, future actions can be more effective at addressing the variety of issues posed by mercury contamination at former extraction and processing sites. This paper provides background on mercury, its occurrences, its health effects, and the mercury mining process. Four cleanup sites that utilized different methods for addressing mercury contamination illustrate how different sources at abandoned mercury mill sites may be addressed to mitigate impacts.

The site was remediated under Superfund due to risk from arsenic and radium-226 in overburden soils. Separate clean-up standards were developed for each mine site for arsenic and radium-226 due to differing ore-body geochemistry. Gamma surveys were used to identify overburden with elevated radium-226 activities and to provide confirmation of visual clean-up of materials. Because arsenic is collocated with radium-226 at the White King mine, gamma surveys reduced the number of arsenic confirmation samples. Secular equilibrium in the uranium-238 decay series was used to determine the extent of leaching of uranium-238 and daughter products from overburden to groundwater. Trilinear geochemical analysis distinguished mineralized groundwater within the ore bodies from regional groundwater and detected any influence from seepage from overburden piles. Remedial actions include neutralization of an acidic mine pond and consolidation of elevated-activity overburden into a pile with a soil/rock cover at White King mine. Ecological toxicity studies determined that neutralization of the pond would provide a benthic community supportive of aquatic wildlife. An overburden pile at the Lucky Lass mine and disturbed areas were covered with clean soil. The remedial actions comply with State of Oregon siting regulations, which required removal of radioactive overburden from the 500-year flood plain. Protection of human health is assured by institutional controls to prevent use of mineralized groundwater and by fencing to prevent site access.

The remote alarm combines the monitoring capabilities of data loggers with a message transmitter that sends a voice message via 2-way radios when an animal enters a monitored area. We tested the remote alarm with food-conditioned American black bears (Ursus americanus) in Yosemite National Park by setting up 6 remote alarms in areas designated off-limits to bears (i.e., campgrounds and parking lots) and alternated nights when the message transmitters on the alarms were activated. We recorded the number of times a radiotagged bear entered an off-limits area, the number of times bear management detected a bear in areas off-limits, and the number of hazing events. Data loggers recorded 153 bear visits by 6 radiotagged bears, 59 with the alarm on and 94 with the alarm off. With the message transmitter activated, bear-managers found bears in areas off-limits 4 times more often than with the message transmitter off. Twelve hazing events occurred with the message transmitters active and 5 with them inactive. The number of bear visits/night to monitored areas was lower when message transmitters were active than when they were inactive, probably because bears entering areas off-limits were more likely to be detected and hazed with the message transmitter on. The remote alarm functioned well and aided park managers with their hazing program to reduce bear-human conflict.

Scenario analysis combined with landscape sciences can be used to characterize uncertainties, test possible impacts and evaluate responses, assist strategic planning and policy formulation, and structure current knowledge to scope the range of potential future conditions. In this study, potential impacts from three wide-ranging scenarios in a large regional area in the northwest United States are compared to current conditions (ca. 1990) of the region in terms of a set of processes that are modeled in a geographic information system (GIS). This study presents an integrated approach to identify areas with potential water quality problems as a result of land cover change projected by stakeholders within the basin. Landscape metrics in conjunction with hydrological process models were used to examine the contribution of land use/land cover to water and sediment yield and identify subwatersheds within the Willamette River Basin (Oregon, USA) that would be most affected in the year 2050 relative to three possible future scenarios which include inherent differences related to conservation, planning, and open development. Specifically, this study provides one example of the use of landscape sciences for environmental assessment that examines the impact of both urban and agricultural development in a large river basin. In particular, it attempts to (1) answer questions that relate to future scenarios that describe contrary positions related to urban development, (2) provide information which can be used to assess the potential changes of the landscape relative to human use, and (3) provide options that could be useful for sustainable management of natural resources and thus minimize future hydrologic and environmental impacts.

For ecological risk assessments (ERAs), the relevant objects of environmental security are social-ecological landscapes (SELs). ERAs, in this case, are less precise than traditional ERAs, but provide results that are more comprehensive and understandable by stakeholders. In this paper, we detect and quantify the scales and spatial patterns of human land use as ecosystem disturbances at different hierarchical levels in a panarchy of SELs by using a conceptual framework that characterizes multi-scale disturbance patterns exhibited on satellite imagery over a four-year time period in Apulia (South Italy). Multi-scale measurements of the composition and spatial configuration of disturbance are the basis for evaluating fragility through multi-scale disturbance profiles, and the identification of scale mismatches revealed by trajectories diverging from the global profile to local spatial patterns. Scale mismatches of disturbances in space and time determine the role of land use as a disturbance source or sink, and may govern the triggering of landscape changes affecting regional biodiversity. This study clarifies the potential roles for environmental security of natural areas and permanent cultivations (olive groves and vineyards) in buffering Mediterranean landscape disturbance dynamics and compensating for disturbances across the whole panarchy of Apulia, allowing for potential landscape planning of disturbance.

Now, recombinant fowl pox and avian paramyxovirus type 1 vaccines with avian influenza H5 gene inserts (+ or - N1 gene insert) are available and licensed. New technologies might overcome existing limitations to make available vaccines that can be grown in tissue culture systems for more rapid production; provide optimized protection, as a result of closer genetic relations to field viruses; allow mass administration by aerosol, in drinking-water or in ovo; and allow easier strategies for identifying infected birds within vaccinated populations (DIVA). The technologies include avian influenza viruses with partial gene deletions, avian influenza-Newcastle disease virus chimeras, vectored vaccines such as adenoviruses and Marek's disease virus, and subunit vaccines. These new methods should be licensed only after their purity, safety, efficacy and potency against avian influenza viruses have been demonstrated, and, for live vectored vaccines, restriction of viral transmission to unvaccinated birds. Use of vaccines in countries affected by highly pathogenic avian influenza will not only protect poultry but will provide additional safety for consumers. Experimental studies have shown that birds vaccinated against avian influenza have no virus in meat and minimal amounts in eggs after HPAI virus challenge, and that replication and shedding from their respiratory and alimentary tracts is greatly reduced.

TI Shedding of sCD14 by bovine neutrophils following activation with bacterial lipopolysaccharide results in down-regulation of IL-8 SO VETERINARY RESEARCH LA English DT Article DE CD14; IL-8; LPS; neutrophil; bovine ID PROGRAMMED CELL-DEATH; SOLUBLE CD14; ESCHERICHIA-COLI; POLYMORPHONUCLEAR LEUKOCYTES; INTRAMAMMARY INFECTION; REDUCES SEVERITY; TNF-ALPHA; EXPRESSION; ENDOTOXIN; RECEPTOR AB CD14, the leukocyte co-receptor for lipopolysaccharide (LPS), is important in the response of bovine polymorphonuclear neutrophil leukocytes (PMN) to Gram-negative bacteria. In other species, the expression of CD14 on the surface of PMN was shown to increase after exposure to inflammatory stimuli. These newly expressed molecules may originate from either an intracellular pool or through new gene expression. We sought to characterize bovine PMN cell surface expression and shedding of CD14 molecules, and CD14's effect on secretion of the chemoattractants IL-8 and IL-1 beta by PMN. Bovine PMN were incubated in RPMI for 20 h at 37 degrees C with LPS (1, 10, 100 mu g/mL). IL-8 release increased with treatment of 1 mu g/mL LPS, but decreased 41.5 and 95% at the 10 and 100 mu g/mL concentrations of LPS, respectively. In contrast, shedding of CD14 from the surface of PMN only increased at the highest concentration of LPS (100 mu g/mL). Secretion of IL-1 beta was similar regardless of the LPS concentration used to stimulate PMN. The effect of PMN concentration (1 x 10(7), 2.5 x 10(7), 5 x 10(7), and 10 x 10(7)/mL) on CD14 cell surface expression and shedding of IL-8 and IL-1 beta were also determined. Shedding of CD14 by PMN increased with increasing concentration of PMN after exposure to 0.1 and 10 mu g/mL of LPS, while secretion of IL-8 decreased. IL-1 beta increased at the highest concentration of PMN. The use of real time polymerase chain reaction showed that CD14 mRNA expression was not different between control and LPS-stimulated cells, indicating that the sCD14 came from either membrane bound CD14 or a preformed pool. Our results demonstrate that release of CD14 from PMN suppresses secretion of IL-8, and may be an important regulatory mechanism for controlling excessive migration of PMN into the bovine mammary gland.

Only in recent years, it was reported to infect greenhouse-grown tomatoes. Genome nucleotide sequences from several European isolates showed extensive sequence identity (> 99%). Recent genome nucleotide sequences from two US isolates (US1 and US2) however showed much greater sequence divergence from that of the European PepMV isolates. My interest in characterizing virus isolates from South America was due to an active commercial tomato seed production in Chile. Through genome sequence comparison and phylogenetic analyses, we may be able to understand the source of virus infection and control this devastating disease from further spreading into new tomato growing regions of the world. Complete genome nucleotide sequences from two PepMV variants (designated as Ch1 and Ch2) were determined from a virus isolate obtained from a commercial tomato seed lot produced in Chile. Using RT-PCR-based genome walking strategy, complete genome sequences from these two variants were determined. Excluding poly (A) tails, the genomes of PepMV Ch1 and Ch2 were 6414 and 6412 nucleotides (nt), respectively. Pairwise comparisons of PepMV Ch1 and Ch2 genomes with other PepMV isolates showed that the highest nucleotide sequence identity was with two US isolates, 98.7% between PepMV Ch1 and US1, and 90.7% between Ch2 and US2. Similar to PepMV US1 and US2, the two Chilean variants were the most divergent from one another (78% nt identity). These two Chilean PepMV variants also shared only 78-86% nucleotide sequence identity to that of five European isolates. The high level of nucleotide sequence identity between Chilean and US isolates suggests a common origin. Phylogenetic analyses with various gene products generated three distinct sequence clusters (or strains): US1 and Ch1 in the first group, US2 and Ch2 in the second, and the European tomato isolates in the third. Based on the host specificity, it was previously suggested that the original pepino isolate should be considered a distinct strain from that of the tomato isolates.

During cell culture passage, two copies of a 132 bp repeat are expanded to over 30 copies. We deleted the two copies of the 132 bp repeat region in a pathogenic MDV and demonstrated that the virus was still pathogenic. The pattern and frequency of tumors in the parental and mutant virus were the same. Early virus replication, and the appearance of persistent neurological disease were also similar between the parental and deleted virus. Nevertheless, wild-type MDV and the deletion virus could be attenuated by serial in vitro cell culture passages. Based upon analyzing the passage 40 viruses, attenuation of the MDV lacking the 132 bp repeats appears to occur in a manner that is analogous to the process occurring wild-type MDV attenuation. Whatever process is involved in the cell culture attenuation of MDV, the mechanism does not involve the 132 bp repeat region. C1 USDA ARS, Avian Dis & Oncol Lab, E Lansing, MI 48823 USA.

In the present study, synchronous somatic embryogenic cultures were developed for Museadinia rotundifolia cv. Darlene and Vitis vinifera cv. Velika. High cell density and presence of 2,4-dichlorophenoxyacetic acid (2,4-D) proved to be essential for the establishment of the suspension cultures. Low cell density and continuous availability of auxin (2,4-D) was crucial for maintenance of suspension cultures. High cell density and withdrawal of 2,4-D is sufficient to advance somatic embryo development toward embryo differentiation and plantlets regeneration. Cells and cell clusters fractionation by density gradient centrifugation in Ficoll solution demonstrated to be a suitable method for separation of subpopulations with various potential for embryo development. The high frequency of synchronous development and differentiation of somatic embryos was attained essentially for the heaviest (at 16-18 % and > 18 % Ficoll layer) cell population.

The assay was conducted on both greenhouse- and field-grown plants. Glyphosate was applied at five rates ranging from 840 to 53 g ae ha(-1). Shikimate accumulation data were generated at 1, 4, 7, and 14 d after application (DAA). Sunflower accumulated shikimate more rapidly and at lower glyphosate rates than the other two species. At 14 DAA, glyphosate at the two highest rates remained detectable in all three species. Plants receiving lower glyphosate doses (210, 105, and 53 g ae ha(-1)) had begun to grow out of the injury, or at least the shikimate levels in the plants were no longer significantly different than that present in the untreated controls. This spectrophotometric assay is both rapid and simple, with respect to other means of detecting shikimate, and it can be used to detect glyphosate drift. For it to be used by crop managers, samples from potentially drift-affected crops should be taken as soon as possible after the suspected drift event or immediately after the appearance of glyphosate injury.

TI Formulation and adjuvant effects on uptake and translocation of clethodim in bermudagrass (Cynodon dactylon) SO WEED SCIENCE LA English DT Article DE absorption; adjuvant; autoradiography; distribution ID SETHOXYDIM; ABSORPTION; BENTAZON AB The effect of formulation and adjuvants on absorption and translocation of 14 C-clethodim was determined at 1, 4, 12, 24, 48, and 72 h after treatment (HAT) in bermudagrass under greenhouse conditions. Absorption of C-14-clethodim with the 0.12 kg L-1 (15 to 85%) formulation was higher than with the 0.24 kg L-1 (5 to 40%) formulation, regardless of presence or absence of adjuvant. There was considerable variation in the effect of adjuvant on C-14-clethodim absorption. When either ammonium sulfate (AMS) or AMS plus crop oil concentrate (COC) was added to the 0.12 kg L-1 formulation, C-14-clethodim absorption increased significantly at all harvest times except at 12 HAT compared with 0.12 kg L-1 formulation alone, whereas, C-14-Clethodim absorption after addition of COC to the 0.12 kg L-1 formulation was similar to the 0.12 kg L-1 formulation alone up to 24 HAT. Conversely, COC enhanced C-14-absorption at all harvest times when added to 0.24 kg L-1 formulation. Most of C-14-clethodim (79 to 100% of absorbed) remained in the treated leaf, independent of formulation or adjuvant. Formulation did not have an impact on distribution of absorbed C-14-clethodim; however, presence of an adjuvant increased movement of C-14-clethodim out of treated leaf. Of the absorbed C-14-label, most remained in the treated leaf C-14-clethodim that translocated out of the treated leaf remained in the shoot, and negligible amount of C-14-clethodim translocated to roots. These results demonstrated improved absorption of clethodim with formulations containing half the active ingredient (0.12 kg L-1) and inclusion of both AMS and COC.

Controlled-environment bioassays of velvetleaf and giant foxtail seed fate in Michigan field soil (Kalamazoo silt loam, 1.1% soil organic matter) were used to determine the role of pathogenic fungi and seed burial depth in fatal germination of these species. Fatal germination at 2 cm seed depth was nonexistent for giant foxtail, and rare (< 10% of seeds studied) for velvetleaf. At greater depths, fatal germination remained close to zero for giant foxtail, whereas it increased to as high as 40% for velvetleaf at a 10-cm burial depth. Cultures taken from fatally germinated velvetleaf seedlings were found to contain Pythium ultimum, a soilborne pathogen known as the causal agent for pea root rot. When samples of infected media taken from these cultures were used to inoculate field soil in pots, fatal germination of velvetleaf from depths of 4 to 6 cm increased, compared with field soil inoculated with sterile media. At seed burial depths of 8 and 10 cm, fatal germination of velvetleaf increased to 20 and 40%, respectively, and was the same for unsterilized soil and P. ultimum-inoculated soil. Given that maximal fatal germination of velvetleaf occurred in the unsterilized soil treatment at the 10 cm depth, burial of newly shed velvetleaf seeds to a 10 cm, or possibly greater, depth with tillage equipment may be a practical way of reducing velvetleaf seed banks through fatal germination.

Research was conducted at the Southern Weed Science Research Unit, Stoneville, MS, to determine cogongrass rhizome mortality with increasing temperature and duration of exposure to heat and to determine if 2,3,5 triphenyl tetrazolium chloride (TTC) could be used to evaluate cogongrass rhizome mortality following heat treatment. Cogongrass rhizome mortality was 100% at 65, 79, 93, 107, 121, 149, 177, and 187 C at time periods greater than or equal to 25, 5, 2.5, 2.5, 2.5, 2, 2 and 1 min, respectively. The duration of heat required for cogongrass mortality decreases as temperature increased. The standard greenhouse bioassay was more effective than tetrazolium chloride in predicting viability of cogongrass rhizomes following heat treatments.

Glyphosate, glufosinate, and MSMA were evaluated at 0.5X, 1X, and 2X rates, with 1X rates of 0.84 kg ae/ha, 0.5 kg ai/ha, and 2.2 kg ai/ha, respectively. Glyphosate and glufosinate provided similar levels of control for most weed species and were often more efficacious than MSMA alone. Glyphosate controlled Palmer amaranth better than glufosinate. Glufosinate controlled hemp sesbania, pitted morningglory, and ivyleaf morningglory better than glyphosate at one location. Weed control was not improved with the addition of MSMA to glyphosate or glufosinate when compared with either herbicide alone. MSMA antagonized glyphosate efficacy on barnyardgrass, browntop millet, hemp sesbania, Palmer amaranth, and redroot pigweed. MSMA antagonized glufosinate efficacy on browntop millet, hemp sesbania, ivyleaf morningglory, johnsongrass, Palmer amaranth, pitted morningglory, prickly sida, redroot pigweed, and velvetleaf. Antagonism of glyphosate or glufosinate by MSMA was often overcome by applying the 2X rate of either herbicide alone. MSMA is not a compatible tank-mixture partner with glyphosate or glufosinate for weed control in cotton. C1 USDA ARS, Prod Res Unit, Stoneville, MS 38776 USA.

MSMA antagonized activity of glyphosate in both weed species. Absorption of C-14-glyphosate in Palmer amaranth was rapid and increased with time from 11.1% at 0.5 h after treatment to 68.1% at 168 HAT. Absorption of C-14-glyphosate in browntop millet ranged from 1.6% at 0.5 HAT to 39.1% at 168 HAT. MSMA in mixture with glyphosate did not affect the absorption of glyphosate. In browntop millet, only 2.8% of the applied radioactivity translocated out of the treated leaf to the rest of the plant when glyphosate was applied in mixture with MSMA compared to 10.8% when glyphosate was applied alone at 72 HAT. Similarly, in Palmer amaranth, 3.2% of the applied radioactivity had translocated out of the treated leaf when glyphosate was applied in mixture with MSMA compared to 10.6% when glyphosate was applied alone. Reduced translocation appears to be the cause of the previously observed antagonism of glyphosate by MSMA. C1 USDA ARS, So Weed Sci Res Unit, Stoneville, MS 38776 USA.

TI Evaluating montana's dyer's woad (Isatis tinctoria) cooperative eradication project SO WEED TECHNOLOGY LA English DT Article DE cost-benefit analysis; early detection; prevention; rapid response ID POPULATION BIOLOGY; INVASIVE PLANTS; MANAGEMENT AB Eradication is often stated as an essential element of weed management. Assessing the costs and benefits of eradication programs is often difficult because doing so requires speculation about the impacts and spread of weeds if eradication measures were not undertaken. The objective of this article is to describe and assess the Montana Dyer's Woad Cooperative Project, a program aimed at eradicating dyer's woad from Montana. The Project comprises four key components: early detection, treatment technologies, repeated site visits with monitoring, and education. To evaluate the success of the Montana Dyer's Woad Cooperative Project, we used monitoring data to observe the change in the number of counties where dyer's woad is present, plotted the trend in population size over time, and evaluated change in infestation size. We also predicted population spread based on the 1999 population size and demographic characteristics of dyer's woad. Dyer's woad has been eradicated from 9 of 13 infested counties in Montana, and infestation sizes have decreased in the remaining infested counties. In some counties, a containment effort was needed in conjunction with repeated inventories and treatment applications to prevent spread while depleting the seedbank to the point where eradication is possible. If not for the Project, our analysis suggests that some dyer's woad populations might consist of millions of plants, potentially covering 39,021 ha in Montana and costing $1.9 million/yr to manage. In comparison, the Project has reduced the total area infested in Montana to 2.6 ha and cost the state only $142,000 for the past 7 yr of management. In Montana, dyer's woad eradication from individual counties has been successful because of persistence and ongoing cooperative efforts.

Individual control tactics often are ineffective and inconsistent, but management systems comprised of several tactics designed to disrupt population dynamics of jointed goatgrass can reduce infestation levels in winter wheat. Tactics are planned to favor decline of seedbank density, reduce seedling emergence in winter wheat, and minimize seed production of plants established in winter wheat. We describe a visual guide that will help producers plan management systems for jointed goatgrass with a diversity of cultural tactics. The guide organizes cultural tactics by decision times of producers during the winter wheat production cycle. Scientists are effectively managing jointed goatgrass in a diversity of production systems by integrating cultural tactics across decision times. C1 USDA ARS, Brookings, SD 57006 USA.

Most of this reduction is attributed to the conversion of timberland to other land uses, especially urban and other developed uses. In areas such as the Puget Sound region, population densities have more than doubled over the last 40 years. Further expansion in urban and developed areas is expected, with timberland a major source for development. We project an 8% reduction over 30 years in forestland area in western Washington. At the some time, urban and other developed areas are projected to roughly double, driven by increases in population and personal income levels. Increased demand for land for residential and other developed uses puts upward pressure on land values, increasing opportunity cost of retaining land in forests and raising the question of what will become of some forests and associated forest resources, such as water and wildlife, if forest owners find it too costly to manage the forest.

The objectives were to test the relationship between visual obstruction readings and standing herbage, develop guidelines for monitoring, and estimate sample size. The relationship between visual obstruction and standing herbage was linear with 2 segments in a piecewise model. Regression coefficients were highly significant (P <= 0.001). Standard error of the estimate for a single mean was 373 kg . ha(-1). Herbage ranged from 89 to 3821 kg . ha(-1) with a mean of 1416 kg . ha(-1). The average number of visually obstructed bands was 6.4 and ranged from 0.21 to 20.4. Cluster analyses grouped the visual obstruction readings into 3 management categories: short, medium, and tall. A minimum of 3 transects (20 stations per transect) is recommended for monitoring areas <= 259 ha (1 section) to be within 20% of the mean at 80% confidence. The protocol developed to monitor standing herbage is accurate, precise, and easy to apply. This tool provides pertinent information for managers to develop guidelines based on the bands and/or standing herbage for monitoring livestock and wildlife use.

The process of emergence is conceptualized as two transition stages which are common and required for all disease emergence, (1) human contact with the infectious agent and (2) cross-species transmission of the agent, and two transition stages which are not required for emergence and appear unavailable to many zoonotic pathogens, (3) sustained human-to-human transmission and (4) genetic adaptation to the human host. The latter two transitions are presumably prerequisites for the pandemic emergence of a pathogen. The themes introduced herein are amplified and explored in detail by the contributors to this volume. Each author explores the mechanisms and unique circumstances by which evolution, biology, history, and current context have contrived to drive the emergence of different zoonotic agents by a series of related events; although recognizable similarities exist among the events leading to emergence the details and circumstances are never repetitive.

Genus Influenza A viruses are true zoonotic agents with many animal reservoirs, whereas genus Influenza B viruses are generally considered to be a virus of humans. The genome of influenza A viruses consists of eight unique segments of single-stranded RNA of negative polarity; they are typed according to their surface proteins, hemagglutinin (HA) and neuraminidase (NA). HA and NA, the major antigenic determinants of influenza A viruses, are present in 16 and nine serologic subtypes, respectively. Annual epidemics and occasional pandemics of influenza in humans depend on the continued evolution of influenza viruses. Although they have numerous potential host populations, most of our genetic and biologic data are obtained from studies of domestic populations of species such as chickens, turkeys, swine, and horses. Concerning wildlife populations, including wild populations of these domesticated species, much less is known. The purpose of this review is to establish what role wildlife populations play in the continued evolution of influenza viruses. Future work needs to determine what chain of events makes it possible for an influenza virus to be successfully transmitted to, and more importantly within, an alternative host population. Even questions as fundamental as which hosts can transmit viruses to humans remain unanswered so far. C1 St Jude Childrens Hosp, Dept Infect Dis, Memphis, TN 38105 USA.

Today, reservoirs of Mycobacterium bovis, the causative agent of tuberculosis in animals and a serious zoonosis, exist in wildlife. The presence of these wildlife reservoirs is the direct result of spillover from domestic livestock in combination with anthropogenic factors such as translocation of wildlife, supplemental feeding of wildlife and wildlife populations reaching densities beyond normal habitat carrying capacities. As many countries attempt to eradicate M. bovis from domestic livestock, efforts are impeded by spillback from wildlife reservoirs. It will not be possible to eradicate M. bovis from livestock until transmission between wildlife and domestic animals is halted. Such an endeavor will require a collaborative effort between agricultural, wildlife, environmental and political interests.

TI Estimating wolverine Gulo gulo population size using quadrat sampling of tracks in snow SO WILDLIFE BIOLOGY LA English DT Article; Proceedings Paper CT 1st International Symposium on Wolverine Research and Management CY JUN 13-15, 2005 CL Jokkmokk, SWEDEN DE Alaska; Gulo gulo; population estimation; sample-unit probability estimator; snow tracking; wolverine; Yukon AB Low densities and wide-ranging behaviour make wolverines Gulo gulo, difficult to monitor. We used quadrat sampling of tracks in snow to estimate wolverine populations. We conducted aerial surveys in upper Turnagain Arm and the Kenai Mountains (TAKM) in south-central Alaska and in Old Crow Flats (OCF) in northern Yukon during March 2004 following procedures for the sample-unit probability estimator (SUPE). This technique uses network sampling of tracks in snow in a stratified random system of quadrats or sample units. In TAKM, we sampled 87 (51%) out of 171 quadrats within a survey area of 4,340 km(2). The estimated density was 3.0 (+/- 0.4 SE) wolverines/1,000 km(2) with a coefficient of variation (CV) of 12.0%. In OCF, we sampled 96 (71%) out of 135 quadrats within a survey area of 3,375 km(2). The estimated density was 9.7 (+/- 0.6 SE) wolverines/1,000 km(2) with a CV of 6.5%. Our results indicated that the SUPE technique is an efficient method of obtaining precise estimates of wolverine population size under markedly different environmental conditions and population densities. We suggest that, where practical, it may be a less labour-intensive and more cost-effective technique for estimating wolverine abundance compared with techniques that do not use probability sampling of tracks.

Because the monk parakeet is a highly visible species and there is often public opposition to lethal control measures, non-lethal methods, such as contraception, are being developed to help control the spread of feral populations. Two gavage studies and one ad libitum nesting study were conducted to assess the efficacy of DiazaCon (TM) as a potential contraceptive for the monk parakeet. The first gavage study compared daily dose levels of 0, 50, 75, and 100 mg DiazaCon T ( kg bodyweight)(-1) administered for 10 consecutive days. Cholesterol concentrations decreased significantly concomitant with a significant increase in desmosterol concentrations in the treated groups, but did not vary between sexes. Cholesterol and desmosterol concentrations did not differ significantly among DiazaCon (TM) groups, and cholesterol remained significantly suppressed 12 weeks after treatment. On the basis of these results, the second gavage study compared 5 or 10 consecutive days of DiazaCon (TM) administration at 50 mg kg(-1) bird(-1) day(-1). Cholesterol concentrations decreased significantly concomitant with a significant increase in desmosterol concentrations in the treated groups, but did not vary between sexes. Cholesterol and desmosterol concentrations did not differ significantly between DiazaCon (TM) groups, and cholesterol remained significantly suppressed 11 weeks after treatment. Parakeets in the nesting study were fed hulled sunflower seeds treated with a target dose of 50 mg DiazaCon (TM) kg(-1) bird(-1) day(-1). Birds consumed enough to receive an average dose of 34 mg kg(-1) pair(-1) day(-1), or 17 mg kg(-1) bird(-1) day(-1). Birds in the treated group laid an average of 1.6 +/- 0.7 eggs per clutch compared with 3.9 +/- 1.1 eggs per clutch in the untreated control group. None of the eggs laid by treated birds hatched compared with 1.1 +/- 0.6 eggs per clutch hatching in the control group. Reproductive inhibition was effective for the length of the breeding season, at which time the study was stopped and no more data were collected. DiazaCon (TM) is a promising avian oral contraceptive that should be further investigated in a field setting with monk parakeets. C1 USDA, APHIS, WS, Natl Wildlife Res Ctr, Ft Collins, CO 80521 USA.

The rats were causing substantial damage to a variety of the 80-ha island's floral and faunal resources. An island-wide grid of elevated bait stations containing anticoagulant (0.005% diphacinone; 50 ppm) rodenticide bait blocks were used to eradicate the rats. The bait stations were modified several times to assure ready access by rats while minimising access by non-target animals, especially crabs and birds. Numerous post-project trapping sessions over six years resulted in no rat captures, suggesting that, indeed, the rats had been eradicated from the island. No non-target losses resulting from the baiting program were observed by field personnel, but they noted what appeared to be a recovery of some of the island's floral and faunal resources. There have been no depredations of endangered sea turtle nests since the eradication. Post-project monitoring sessions revealed the presence of a growing house mouse (Mus musculus) population on the island. The threats posed by, and potential management strategies for, this introduced pest species are being investigated. This is the first successful rat eradication on a sizable island, using diphacinone bait blocks with a unique, elevated bait-station system. Diphacinone can provide an alternative to the highly toxic brodifacoum and may help reduce non-target hazards in some situations, although several applications are generally required.

Acoustic wave behavior SO WOOD AND FIBER SCIENCE LA English DT Article DE acoustic velocity; time-of-flight; dilatational wave; Poisson's ratio; standing trees; logs AB Acoustic wave velocities in standing trees of five softwood species were measured by the time-of-flight (TOF) method. Tree velocities were compared with acoustic velocities measured in corresponding butt logs through a resonance acoustic method. The experimental data showed a skewed relationship between tree and log acoustic measurements. For most trees tested, observed tree velocities were significantly higher than log velocities. The results indicate that time-of-flight measurement in standing trees is likely dominated by dilatational or quasi-dilatational waves rather than one-dimensional plane waves. To make appropriate adjustments of observed tree velocities, two analytical models were developed for the species evaluated. Both the multivariate regression model and dilatational wave model were effective in eliminating deviation between tree and log velocity and reducing variability in velocity prediction.

In addition, the globalization of wood product markets is exposing U.S. consumers to new species. This research evaluates consumer preferences for six domestic wood species-three from the eastern United States and three from the western United States. The survey was designed to evaluate four treatment effects including two price points and the presence vs. absence of species identification labels. Four different pieces of furniture (dresser, entertainment center, hutch, and desk) were considered. Data were collected at Pacific Northwest home shows in late 2004 and early 2005. There were no significant differences in the species preferences expressed by consumers between price points at either level of species information. This indicates that furniture price did not significantly influence species preferences for the selected pieces. However, there were significant differences in consumer species preferences with and without labels at the higher price points. For the entertainment center, preference was greater for cherry (Prunus serotina Ehrh.) when species information was provided, but oak (Quercus rubra L.) was preferred when no species label was provided. When viewing the hutch, consumers preferred cherry and maple (Acer saccharum Marsh.) when species labels were present, whereas oak, birch (Betula papyrifera Marsh.), and spruce (Picea glauca (Moench) Voss) were preferred when no species labels were present. Lastly, for the desk, spruce was more preferred with no information, and cherry was more preferred when species information was included. No preference differences were detected for the dresser. Overall, consumers expressed the highest preference for cherry; the second most preferred species was oak. With the exception of oak, consumer knowledge of the species investigated was low. Based on the results of this study, it is recommended that species information be provided for furniture pieces made from cherry and maple at higher price points, as preferences for these species can be enhanced in such cases.

TI Two-dimensional finite element heat transfer model of softwood. Part III. Effect of moisture content on thermal conductivity SO WOOD AND FIBER SCIENCE LA English DT Article DE finite element modeling; thermal conductivity; moisture content; heat transfer; cellular structure; geometric model AB The anisotropy of wood creates a complex problem for solving heat and mass transfer problems that require analyses be based on fundamental material properties of the wood structure. Most heat transfer models for softwood use average thermal properties across either the radial or tangential direction and do not differentiate the effects of cellular alignment or differences in earlywood and latewood. A two-dimensional finite element model that considers these basic structural characteristics was developed to determine the effective thermal conductivity as a function of cell alignment, cell porosity, and moisture content. This paper extends the initial model to include moisture content effects from the oven-dry to the fully saturated condition. The model predicts thermal conductivity values as a function of density and Moisture content. Comparisons are made with established empirical equations found in the literature for the thermal conductivity of wood. The models developed in this study series are useful for enhancing our understanding of fundamental heat transfer effects in various wood boards. C1 USDA, Forest Prod Lab, Madison, WI 53726 USA.

Ponderosa pine in central New Mexico was chosen for study. Peroxide bleaching was used as a pretreatment to remove extraneous color and still yield usable wood for image analysis. The cores were bleached in 3% peroxide raised to pH 12 and heated to 60 degrees C, and then they were soaked in 95% ethanol and rinsed in water. The cores were dried slowly to avoid checking or cracking. This treatment removed heartwood color while leaving the wood reasonably sound. Wood reflectance and latewood width were measured using reflected-light image analysis. For dendroclimatic modeling. best-subsets regression was used to determine the strongest predictive model, which was May-September rainfall using latewood reflectance and latewood width. The ability to dendroclinlatically model and reconstruct summer precipitation is contingent on having latewood reflectance (density) measurements, and reconstructing summer precipitation in the Southwest will enhance paleoclimatology of the region. Image analysis with reflected white light is thus closer to being more widely applicable in dendrochronology. C1 Univ Arizona, Lab Tree Ring Res, Tucson, AZ 85721 USA.
