We selected 30 stormwater-management ponds (average 0.1ha), approximately 50km from Seattle-Tacoma International Airport, as surrogates to on-airport facilities. We conducted 46 weeks of avian surveys (between 14 February 2005 and 17 February 2006) and evaluated model fit of 6 a priori models relative to pond use by an avian group via Kullback-Leibler information. Our full model, composed of pond surface area (sa), ratio of area of open water to area of emergent and woody vegetation (ow:ew), perimeter irregularity, and geographic isolation, was among 3 best approximating models for pond use by 9 of 13 groups (within Anatidae, Ardeidae, Charadriidae, Columbidae, Accipitridae, Laridae, and Rallidae) considered. The full model and models lacking sa or ow:ew were indistinguishable in fit for a group composed of avian species considered hazardous to aviation. For models selected, Akaike weights (i.e., relative likelihoods) ranged from 0.869 to 0.994. In contrast, relative likelihood for a mean model (i.e., a model including only an intercept) was <10 super(-) super(4) for all groups. We suggest that designs of stormwater-management ponds at airports in the Pacific Northwest should minimize the pond perimeter via circular or linear designs. Also, ponds should be located so as to reduce the number and proximity of other water resources within 1km. For existing stormwater-management ponds at airports, we suggest reducing the availability of open water via covering or drawdown.

8288449 AB - Vegetation water content (VWC) is one of the most important parameters for the successful retrieval of soil moisture content from microwave data. Normalized Difference Infrared Index (NDII) is a widely-used index to remotely sense Equivalent Water Thickness (EWT) of leaves and canopies; however, the amount of water in the foliage is a small part of total VWC. Sites of corn (Zea mays), soybean (Glycine max), and deciduous hardwood woodlands were sampled to estimate EWT and VWC during the Soil Moisture Experiment 2005 (SMEX05) near Ames, Iowa, USA. Using a time series of Landsat 5 Thematic Mapper, Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) and Advanced Wide Field Sensor (AWiFS) imagery, NDII was related to EWT with R super(2) of 0.85; there were no significant differences among land-cover types. Furthermore, EWT was linearly related to VWC with R super(2) of 0.87 for corn and 0.48 for soybeans, with a significantly larger slope for corn. The 2005 land-cover classification product from the USDA National Agricultural Statistics Service had an overall accuracy of 92% and was used to spatially distribute VWC over the landscape. SMEX05 VWC versus NDII regressions were compared with the regressions from the Soil Moisture Experiment 2002 (SMEX02), which was conducted in the same study area. No significant difference was found between years for corn (P=0.13), whereas there was a significant difference for soybean (P=0.04). Allometric relationships relate the size of one part of a plant to the sizes of other parts, and may be the result from the requirements of structural support or material transport. Relationships between NDII and VWC are indirect, NDII is related to canopy EWT, which in turn is allometrically related to VWC.

Lightning also impacts this system on a smaller scale by causing individual tree mortality. The objective of this study was to determine mortality due to lightning and other agents in longleaf stands on the Ocala National Forest in central Florida and to quantify lightning ignited fire. Mortality from lightning was also tracked in longleaf stands on the Savannah River Site in South Carolina. Lightning killed more trees than any other agent with a mean mortality of nearly 1tree/3ha/yr in Florida and 1tree/8ha/yr in South Carolina. The probability of a tree being struck by lightning increased as a function of tree height at both sites, i.e. lightning preferentially removed the largest trees from the stand. In addition lightning strikes were clumped within stands, sometimes killed multiple trees with a single strike, and often hit trees on the edge of existing gaps. The combination of these processes means gaps suitable for regeneration within longleaf stands are created quite rapidly. This information provides guidelines for the development of selection harvest systems based on this natural disturbance. Although lightning activity was greatest during the summer months in Florida and most fires occurred in June, the probability of a strike causing a fire was highest in February to May.

But the impacts of these treatments on Piedmont forests are not well understood. We examined the effects of prescribed burning, thinning, and a combination of burning and thinning on community composition of Pinus taeda/Pinus echinata forests in the South Carolina Piedmont to identify changes in community structure and species composition. Overstory basal area was reduced across all treatments. The combination of thinning and burning resulted in a substantial increase in sapling density, whereas the burn-only decreased slightly after 3 years. Seedling density for all tree species increased across all treatment units during the same time span. In addition, cover of grasses and forbs increased in the burn-only and thin+burn treatments. Treatments appeared to affect understory life forms differently with the burn-only treatment encouraging forb cover while the thin+burn treatment promoted shrub and graminoid abundance. Non-metric multidimensional scaling (NMS) indicated rapid changes in understory composition for the burn-only and thin+burn treatments, whereas the thin-only treatment showed a more gradual shift over time.

AN - 69189891; 18416554 AB - Acremonium zeae has been characterized as a protective endophyte of maize and displays antifungal activity against other fungi. Pyrrocidines A and B were discovered to be the metabolites accounting for this activity. During a population survey of A. zeae isolates from maize seeds produced in nine states to determine their ability to produce pyrrocidines, another metabolite of A. zeae, unrelated to the pyrrocidines, was found to have widespread occurrence (105 of 154 isolates) and to be produced in amounts comparable to the pyrrocidines. Further chemical studies of fermentation extracts of an A. zeae isolate (NRRL 45893) from maize led to the identification of a new compound, dihydroresorcylide, the saturated analogue of cis-resorcylide. Also identified were the two diastereomers of 7-hydroxydihydroresorcylide. Dihydroresorcylide and pyrrocidines A and B were detected by LC-APCI-MS in symptomatic maize kernels from ears that were wound-inoculated in the milk stage with A. zeae NRRL 34559.

AN - 69183220; 18380463 AB - Diphenylamine metabolism and ethylene action were evaluated as factors influencing the development of 'Braeburn' apple internal browning and cavitation during cold storage. Apples treated with the antioxidant diphenylamine (DPA) and/or the ethylene action inhibitor 1-methylcyclopropene (1-MCP) were held at 1 degrees C for up to 6 months in air or a controlled atmosphere (CA) containing 1 kPa of O2 and 3 kPa of CO2. Cortex tissues from fruit without disorders as well as from symptomatic and asymptomatic areas of fruit with disorders were analyzed for DPA and DPA derivative content. Internal browning and cavities developed in control and 1-MCP-treated fruit stored in CA, whereas air-stored and CA fruit treated with DPA or with DPA and 1-MCP prior to storage did not develop disorders. Depending on the storage regimen and duration, less DPA was detected in 1-MCP-treated fruit. The 4-hydroxydiphenylamine (4OHDPA) content of control fruit decreased during air storage duration but increased between 2 and 4 months in CA storage. 4OHDPA content in 1-MCP-treated fruit increased with storage duration in CA but not air. N-Nitrosodiphenylamine (NODPA) was detected after 2 months in control fruit stored in air or CA and in 1-MCP-treated fruit stored in CA, and NODPA content in control fruit was higher compared to that in 1-MCP-treated fruit. Accumulation of 4-methoxydiphenylamine (4MeODPA) in control fruit stored in air increased with storage duration, but 4MeODPA content did not change in 1-MCP-treated fruit stored in air or CA. 2-Nitrodiphenylamine content was reduced by prestorage treatment with 1-MCP, but storage environment and duration had no effect on its accumulation. The results indicate that CA storage increases the risk of disorder development in 'Braeburn' apples, that DPA can prevent disorder development, and that the content of DPA and DPA derivatives is influenced by storage environment and ethylene action. A clear relationship between DPA derivative formation and storage conditions that promote internal browning was not apparent.

8199990 AB - Bacterial lipopolysaccharide (LPS) is a key mediator in the vascular leak syndromes associated with Gram-negative bacterial infections. LPS opens the paracellular pathway in pulmonary vascular endothelia through protein tyrosine phosphorylation. We now have identified the protein-tyrosine kinases (PTKs) and their substrates required for LPS-induced protein tyrosine phosphorylation and opening of the paracellular pathway in human lung microvascular endothelial cells (HMVEC-Ls). LPS disrupted barrier integrity in a dose- and time-dependent manner, and prior broad spectrum PTK inhibition was protective. LPS increased tyrosine phosphorylation of zonula adherens proteins, VE-cadherin, gamma -catenin, and p120 super(ctn). Two SRC family PTK (SFK)-selective inhibitors, PP2 and SU6656, blocked LPS-induced increments in tyrosine phosphorylation of VE-cadherin and p120 super(ctn) and paracellular permeability. In HMVEC-Ls, c-SRC, YES, FYN, and LYN were expressed at both mRNA and protein levels. Selective small interfering RNA-induced knockdown of c-SRC, FYN, or YES diminished LPS-induced SRC Tyr super(416) phosphorylation, tyrosine phosphorylation of VE-cadherin and p120 super(ctn), and barrier disruption, whereas knockdown of LYN did not. For VE-cadherin phosphorylation, knockdown of either c-SRC or FYN provided total protection, whereas YES knockdown was only partially protective. For p120 super(ctn) phosphorylation, knockdown of FYN, c-SRC, or YES each provided comparable but partial protection. Toll-like receptor 4 (TLR4) was expressed both on the surface and intracellular compartment of HMVEC-Ls. Prior knockdown of TLR4 blocked both LPS-induced SFK activation and barrier disruption. These data indicate that LPS recognition by TLR4 activates the SFKs, c-SRC, FYN, and YES, which, in turn, contribute to tyrosine phosphorylation of zonula adherens proteins to open the endothelial paracellular pathway.

AN - 815551293; 18389224 AB - Intoxication and infection caused by foodborne pathogens are important problems worldwide, and screening tests for multiple pathogens are needed because foods may be contaminated with multiple pathogens and/or toxic metabolites. We developed a 96-well microplate, multiplex antibody microarray method to simultaneously capture and detect Escherichia coli O157:H7 and Salmonella enterica serovar Typhimurium (S. typhimurium), as well as a biomolecule (chicken immunoglobulin G or IgG employed as a proteinaceous toxin analog) in a single sample. Microarrayed spots of capture antibodies against the targeted analytes were printed within individual wells of streptavidin-coated polystyrene 96-multiwell microtiter plates and a sandwich assay with fluorescein- or Cy3-labeled reporter antibodies was used for detection. (Printing was achieved with a conventional microarray printing robot that was operated with custom-developed microplate arraying software.) Detection of the IgG was realized from ca. 5 to 25 ng/mL, and detection of E. coli O157:H7 and S. typhimurium was realized from ca. 10(6) to 10(9) and ca. 10(7) to 10(9) cells/mL, respectively. Multiplex detection of the two bacteria and the IgG in buffer and in culture-enriched ground beef filtrate was established with a total assay (including detection) time of ca. 2.5 h. Detection of S. typhimurium was largely unaffected by high concentrations of the other bacteria and IgG as well as the ground beef filtrate, whereas a small decrease in response was observed for E. coli O157:H7. The multiwell plate, multiplex antibody microarray platform developed here demonstrates a powerful approach for high-throughput screening of large numbers of food samples for multiple pathogens and toxins.

AN - 71651490; 18533434 AB - Aedes aegypti (L.) (Diptera: Culicidae) is the primary vector of both dengue and yellow fever. Use of insecticides is one of the primary ways to control this medically important insect pest. However, few new insecticides have been developed for mosquito control in recent years. As a part of our effort to develop new insecticides to control mosquitoes, an inhibitor of apoptosis protein 1 gene in Aedes aegypti (AaeIAP1) was targeted for the development of molecular pesticides. Herein, for the first time, we report that topically applied AaeIAP1 double-stranded RNA products are able to kill female adults of Ae. aegypti. Our results indicate that critical pathways or genes could be targeted to develop molecular pesticides for the control of medically important diseases vectors.

AN - 71649422; 18533436 AB - The Santa Luiza strain of the southern cattle tick, Boophilus microplus (Canestrini) (Acari: Ixodidae), is resistant to both permethrin and amitraz. A study was conducted at the USDA Cattle Fever Tick Research Laboratory in Texas to investigate the genetic basis of permethrin resistance with cross-mating experiments, and to determine the mechanisms of permethrin resistance through synergist bioassays and biochemical analysis of esterase profiles. The Muñoz strain, an acaricide-susceptible reference strain, was used as the susceptible parent and the Santa Luiza strain, originating in Brazil, was used as the resistant parent. The Food and Agriculture Organization larval packet test was used to measure the levels of susceptibility of larvae of the parental strains, F1, backcross, F2, and F3 generations to permethrin. Results of reciprocal crossing experiments suggested that permethrin resistance was inherited as an incomplete recessive trait. There was no significant maternal effect on larval progeny's susceptibility to permethrin in the F1 and subsequent generations. The values of the degree of dominance were estimated at -0.700 and -0.522 for the F1 larvae with resistant and susceptible female parents, respectively. Results of bioassays on larval progeny of the F1 backcrossed with the resistant parent strain and of the F2 generations suggested that one major gene was responsible for permethrin resistance in the Santa Luiza strain. Selection of F3 larvae with either permethrin or amitraz led to significantly increased resistance to both permethrin and amitraz, indicating a close linkage between genes responsible for permethrin and amitraz resistance. The possible involvement of metabolic enzymes in permethrin resistance in the Santa Luiza strain of B. microplus was dismissed by the lack of enhanced synergism by TPP or PBO, as observed in synergist bioassays, as well as by the lack of enhanced esterase activity in the Santa Luiza strain relative to the susceptible strain. The results of this study suggest that other mechanisms, including a possible new sodium channel mutation that is different from the one currently known, may be responsible for permethrin resistance in the Santa Luiza strain of B. microplus.

AN - 71648894; 18533432 AB - Cytochrome c is a highly conserved protein that is found in many multicellular and unicellular organisms. Cytochrome c is a critical intermediate in apoptosis: a controlled form of cell death that kills cells as part of their natural process of development and in response to environmental condition. To detect whether cytochrome c of the mosquito Aedes aegypti (L.) (AeaCytC) is developmentally regulated, we used quantitative real-time polymerase chain reaction (PCR) to examine AeaCytC gene expression levels in different developmental stages ofAe. aegypti. Quantitative real-time PCR showed that AeaCytC was expressed in each developmental stage, at different points in time, and it was highly expressed in teneral female Ae. aegypti. Ae. aegypti cytochrome c protein (AeaCYTC) was detected only in adult mosquitoes, not in early developmental stages of Ae. aegypti. We also investigated the effect of certain environmental factors (e.g., temperature, UV-light, and permethrin insecticide) on AeaCytC gene and AeaCYTC protein expression in adult mosquitoes, and we found that response varied with age. These results suggest that AeaCytC gene and AeaCYTC protein play functional roles in the development of Ae. aegypti and the differential expression of cytochrome c has potential as a biomarker for environmental and chemical stress.

AN - 71641930; 18522020 AB - Catalytic infrared (IR) heating was investigated to determine its effect on Salmonella enterica serovar Enteritidis population sizes on raw almond kernels. Using a double-sided catalytic IR heating system, a radiation intensity of 5,458 W/m2 caused a fast temperature increase at the kernel surface and minimal temperature differences between the top and bottom kernel surfaces. Exposure of dry kernels to IR heat for 30, 35 and 45 s resulted in maximum kernel surface temperatures of 90, 102, and 113 degrees C, and when followed by immediate cooling at room temperature, yielded a 0.63-, 1.03-, and 1.51-log reduction in S. enterica population sizes, respectively. The most efficacious decontamination treatment consisted of IR exposure, followed by holding of the kernels at warm temperature for 60 min, which effected a greater than 7.5-log reduction in S. enterica on the kernels. During that treatment, the kernel surface temperature rose to 109 degrees C and gradually decreased to 80 degrees C. Similar IR and holding treatments with lower maximum kernel surface temperatures of 104 and 100 degrees C yielded reductions of 5.3 and 4.2 log CFU/g kernel, respectively. During these treatments, moisture loss from the kernels was minimal and did not exceed 1.06%. Macroscopic observations suggested that kernel quality was not compromised by the IR-holding combination treatment, as skin morphology, meat texture, and kernel color were indistinguishable from those of untreated kernels. Our studies indicate that IR heating technology is an effective dry pasteurization for raw almonds.

AN - 70418440; 17412479 AB - The concentrations of sediment and turbidity in stream water were monitored during culvert removals to determine the short term effects of road obliteration. Sediment concentration was measured at 11 stream crossings among two locations in Idaho and one in Washington. Sediment concentration immediately below the culvert outlet exceeded levels above the culvert outlet by at least three orders of magnitude at all stream crossings. Sediment yields ranged from 170 to less than 1kg in the 24-h period following culvert removal. Turbidity exceeded the regulatory limits during culvert removal at all locations monitored in this study and remained above the limits beyond the monitoring periods of 24h at four of the locations. Sediment concentrations 100m downstream of the culvert outlet were reduced by an order of magnitude, but did not change the turbidity values sufficiently to meet regulatory limits. Sediment concentrations an average of 810m downstream of the culvert outlet were similar to sediment concentrations above the culvert for the entire excavation period and turbidity regulations were met. Mitigation consisting of two straw bales placed in the stream caused a significant reduction in sediment yield from an average of 67kg to an average of 1.6kg.

AN - 70418202; 17597286 AB - We compared the efficacy of matrix based fertilizers (MBFs) formulated to reduce NO3-, NH4+, and total phosphorus (TP) leaching, with Osmocoate 14-14-14, a conventional commercial slow release fertilizer (SRF) and an unamended control in three different soil textures in a greenhouse column study. The MBFs covered a range of inorganic N and P in compounds that are relatively loosely bound (MBF 1) to more moderately bound (MBF 2) and more tightly bound compounds (MBF 3) mixed with Al(SO4)3H2O and/or Fe2(SO4)3 and with high ionic exchange compounds starch, chitosan and lignin. When N and P are released, the chemicals containing these nutrients in the MBF bind N and P to a Al(SO4)3H2O and/or Fe2(SO4)3 starch-chitosan-lignin matrix. One milligram (8000 spores) of Glomus intradices was added to all formulations to enhance nutrient uptake. In all three soil textures the SRF leachate contained a higher amount of NH4+, NO3- and TP than leachate from all other fertilizers. In all three soils there were no consistent differences in the amount of NH4+, NO3- and TP in the MBF leachates compared to the control leachate. Plants growing in soils receiving SRF had greater shoot, root and total biomass than all MBFs regardless of Al(SO4)3H2O or Fe2(SO4)3 additions. Arbuscular mycorrhizal infection in plant roots did not consistently differ among plants growing in soil receiving SRF, MBFs and control treatments. Although the MBFs resulted in less plant growth in this experiment they may be applied to soils growing plants in areas that are at high risk for nutrient leaching to surface waters.

AN - 69277730; 18401535 AB - Sorption of the herbicides (acetochlor, atrazine, 2,4-D: , chlorotoluron, MCPA and trifluralin) in their commercially available formulations was characterized on six agricultural soils from Slovakia. Weak acid herbicides (2,4-D: and MCPA) were the least sorbed, whereas weak base such as atrazine and nonionic herbicides were the most sorbed in the order: atrazine < acetochlor approximately chlorotoluron < trifluralin, which was closely related to the hydrophobicity of herbicides expressed as logKOW. The KF values positively correlated with soil organic carbon content for all herbicides. Moreover, all herbicides were the most sorbed by Vertisol with relatively high smectite clay content in proportion to organic carbon content. The KOC values for each herbicide showed a smaller variation among soils (excluding Vertisol) than the KF and were used to compare soil mobility potential of herbicides.

AN - 69197909; 18344330 AB - The products synthesized from a hybrid polyketide synthase/nonribosomal peptide synthetase gene cluster in the genome of Pseudomonas fluorescens Pf-5 were identified using a genomics-guided strategy involving insertional mutagenesis and subsequent metabolite profiling. Five analogs of rhizoxin, a 16-member macrolide with antifungal, phytotoxic, and antitumor activities, were produced by Pf-5, but not by a mutant with an insertion in the gene cluster. The five rhizoxin analogs, one of which had not been described previously, were differentially toxic to two agriculturally important plant pathogens, Botrytis cinerea and Phytophthora ramorum. The rhizoxin analogs also caused swelling of rice roots, a symptom characteristic of rhizoxin itself, but were less toxic to pea and cucumber roots. Of the rhizoxin analogs produced by Pf-5, the predominant compound, WF-1360 F, and the newly described compound 22Z-WF-1360 F were most toxic against the two plant pathogens and three plant species. These rhizoxin analogs were tested against a panel of human cancer lines, and they exhibited potent but nonselective cytotoxicity. This study highlights the value of the genomic sequence of the soil bacterium P. fluorescens Pf-5 in providing leads for the discovery of novel metabolites with significant biological properties.

AN - 69184037; 18453405 AB - Runoff from farm fields is a common source of herbicide residues in surface waters. Incorporation by irrigation has the potential to reduce herbicide runoff risks. To assess impacts, rainfall was simulated on plots located in a peanut (Arachis hypogaea L.) field in Georgia's Atlantic Coastal Plain region after pre-emergence application of metolachlor (2-chloro-N-(2-ethyl-6-methylphenyl)-N-[(1S)-2-methoxy-1-methylethyl]-acetamide) and pendimethalin (N-(1-ethylpropyl)-3,4-dimethyl-2,6-dinitro-benzenamine). Runoff, sediment, and herbicide loss as function of strip tillage (ST) versus conventional tillage (CT) were compared with and without irrigation (12.5 mm) after application of an herbicide tank mixture. For the CT system, metolachlor runoff was reduced 2x and pendimethalin 1.2x when compared with the non-irrigated treatment. The difference in irrigated and non-irrigated metolachlor means was significant (P = 0.05). Irrigation reduced metolachlor runoff by 1.3x in the ST system, but there was a 1.4x increase for pendimethalin. Overall results indicated that irrigation incorporation reduces herbicide runoff with the greatest impact when CT is practiced and products like metolachlor, which have relatively low K(oc) and high water solubility, are used. The lower ST system response was likely due to a combination of spray interception and retention by the ST system cover crop mulch and higher ST soil organic carbon content and less total runoff. During the study, the measured K(oc) of both herbicides on runoff sediment was found to vary with tillage and irrigation after herbicide application. Generally, K(oc) was higher for ST sediment and when irrigation incorporation was used with the CT system. These results have significant implications for simulation model parametization.

AN - 69182084; 18453436 AB - Bark beetles (Coleoptera: Curculionidae, Scolytinae) are recognized as the most important tree mortality agent in western coniferous forests. A common method of protecting trees from bark beetle attack is to saturate the tree bole with carbaryl (1-naphthyl methylcarbamate) using a hydraulic sprayer. In this study, we evaluate the amount of carbaryl drift (ground deposition) occurring at four distances from the tree bole (7.6, 15.2, 22.9, and 38.1 m) during conventional spray applications for protecting individual lodgepole pine (Pinus contorta Dougl. ex Loud.) from mountain pine beetle (Dendroctonus ponderosae Hopkins) attack and Engelmann spruce (Picea engelmannii Parry ex Engelm.) from spruce beetle (D. rufipennis [Kirby]) attack. Mean deposition (carbaryl + alpha-naphthol) did not differ significantly among treatments (nozzle orifices) at any distance from the tree bole. Values ranged from 0.04 +/- 0.02 mg carbaryl m(-2) at 38.1 m to 13.30 +/- 2.54 mg carbaryl m(-2) at 7.6 m. Overall, distance from the tree bole significantly affected the amount of deposition. Deposition was greatest 7.6 m from the tree bole and quickly declined as distance from the tree bole increased. Approximately 97% of total spray deposition occurred within 15.2 m of the tree bole. Application efficiency (i.e., percentage of insecticide applied that is retained on trees) ranged from 80.9 to 87.2%. Based on review of the literature, this amount of drift poses little threat to adjacent aquatic environments. No-spray buffers of 7.6 m should be sufficient to protect freshwater fish, amphibians, crustaceans, bivalves, and most aquatic insects. Buffers >22.9 m appear sufficient to protect the most sensitive aquatic insects (Plecoptera).

AN - 69182015; 18453406 AB - Soil bacteria have developed novel metabolic abilities resulting in enhanced atrazine degradation. Consequently, there is a need to evaluate the effects of enhanced degradation on parameters used to model atrazine fate and transport. The objectives of this study were (i) to screen Colorado (CO) and Mississippi (MS) atrazine-adapted and non-adapted soil for genes that code for enzymes able to rapidly catabolize atrazine and (ii) to compare atrazine persistence, Q(10), beta, and metabolite profiles between adapted and non-adapted soils. The atzABC and/or trzN genes were detected only in adapted soil. Atrazine's average half-life in adapted soil was 10-fold lower than that of the non-adapted soil and 18-fold lower than the USEPA estimate of 3 to 4 mo. Q(10) was greater in adapted soil. No difference in beta was observed between soils. The accumulation and persistence of mono-N-dealkylated metabolites was lower in adapted soil; conversely, under suboptimal moisture levels in CO adapted soil, hydroxyatrazine concentrations exceeded 30% of the parent compounds' initial mass. Results indicate that (i) enhanced atrazine degradation and atzABC and/or trzN genes are likely widespread across the Western and Southern corn-growing regions of the USA; (ii) persistence of atrazine and its mono-N-dealkylated metabolites is significantly reduced in adapted soil; (iii) hydroxyatrazine can be a major degradation product in adapted soil; and (iv) fate, transport, and risk assessment models that assume historic atrazine degradation pathways and persistence estimates will likely overpredict the compounds' transport potential in adapted soil.

AN - 69178842; 18454810 AB - Data from epidemiologic, experimental, and animal studies indicate that diet plays an important role in the etiology of gastric cancer. High intake of fresh fruits and vegetables, lycopene and lycopene-containing food products, and potentially vitamin C and selenium may reduce the risk for gastric cancer. Data also suggest that high intake of nitrosamines, processed meat products, salt and salted foods, and overweight and obesity are associated with increased risk for gastric cancer. However, current data provide little support for an association of beta-carotene, vitamin E, and alcohol consumption with risk for gastric cancer.

AN - 69123335; 18363796 AB - Bacteria that survive under variable conditions possess an assortment of genetic regulators to meet these challenges. The group IV or extracytoplasmic function (ECF) sigma factors regulate gene expression in response to specific environmental signals by altering the promoter specificity of RNA polymerase. We have undertaken a study of PvdS, a group IV sigma factor encoded by Pseudomonas syringae pv. tomato DC3000 (DC3000), a plant pathogen that is likely to encounter variations in nutrient availability as well as plant host defences. The gene encoding PvdS was previously identified by sequence similarity to the Pseudomonas aeruginosa orthologue, which directs transcription of genes encoding the biosynthesis of pyoverdine, a siderophore involved in iron acquisition, and is responsible for the characteristic fluorescence of the pseudomonads. We identified 15 promoters regulated by PvdS in DC3000 and characterized the promoter motif using computational analysis. Mutagenesis of conserved nucleotides within the motif interfered with promoter function and the degree of the effect was different depending on which region of the motif was mutated. Hidden Markov models constructed from alignments of sequence motifs extracted from DC3000 and PAO1 were used to query genomes of DC3000 and other fluorescent pseudomonads for similar motifs. We conclude that the role of PvdS as a regulator of pyoverdine synthesis is conserved among the fluorescent pseudomonads, but the promoters recognized by PvdS orthologues may differ subtly from species to species.

AN - 69123326; 18420993 AB - Cold air or ice water can be used to chill poultry carcasses after slaughter. The objective of this study was to compare the effect of 2 chill methods on broiler carcass bacteria. Broiler carcasses were cut in half along the dorsal-ventral midline; one half was subjected to an ice-water immersion chill in an agitated bath for 50 min, whereas the reciprocal half was subjected to an air chill in a 1 degrees C cold room for 150 min. Total aerobic bacteria, coliforms, Escherichia coli, and Campylobacter were enumerated from half-carcass rinses. Species of Campylobacter isolates was determined by a commercial PCR method, which was followed by molecular subtyping with pulsed-field gel electrophoresis and determination of antimicrobial susceptibility to 9 drugs. Although significantly fewer of each bacterial type were detected per milliliter from immersion-chilled carcasses than from air-chilled carcasses, in each case the difference was less than 1 log(10) cfu/mL. Chilling method did not affect species; both Campylobacter jejuni and Campylobacter coli were recovered. Results of pulsed-field gel electrophoresis subtyping did not suggest that either chilling method selected for any specific subtypes; most subtypes were found on carcass halves used for both the air chill and water immersion chill. Resistance to 2 antimicrobial drugs was noted in 9 C. coli isolates, 6 from air-chilled carcass halves and 3 from immersion-chilled carcass halves. These data showed that immersion-chilled carcasses had lower numbers of bacteria; however, the difference was not large and may have been due to simple dilution. Both methods were effective for lowering carcass temperature, and neither chilling method seemed to select for specific species, subtypes, or antimicrobial-resistant Campylobacter.

AN - 69117697; 18346134 AB - To establish a system that greatly increases the gene-targeting frequency in Aspergillus parasiticus. The ku70 gene, a gene of the nonhomologous end-joining (NHEJ) pathway, was replaced by the nitrate reductase gene (niaD) in A. parasiticus RHN1 that accumulates O-methylsterigmatocystin (OMST). The NHEJ-deficient strain, RHDeltaku70, produced conidia, sclerotia and OMST normally. It had identical sensitivity as RHN1 to the DNA-topoisomerase I complex inhibitor, camptothecin, and the DNA-damaging agent, melphalan. For targeting an aflatoxin biosynthetic pathway gene, adhA, partial restriction enzyme recognition sequences in its flanking regions were manipulated to create homologous ends for integration. Using a linearized DNA fragment that contained Aspergillus oryzae pyrithiamine resistance gene (ptr) marker the adhA-targeting frequency in RHDeltaku70 reached 96%. The homologous recombination pathway is primarily responsible for repair of DNA damages in A. parasiticus. The NHEJ-deficient RHDeltaku70, easy creation of homologous ends for integration, and the ptr-based selection form a highly efficient gene-targeting system. It substantially reduces the time and workload necessary to obtain knockout strains for functional studies. The developed system not only streamlines targeted gene replacement and disruption but also can be used to target specific chromosomal locations like promoters or intergenic regions. It will expedite the progresses in the functional genomic studies of A. parasiticus and Aspergilllus flavus.

AN - 69108095; 18188624 AB - Grass lignocelluloses, such as those in corn and switchgrass, are a major resource in the emerging cellulose-to-ethanol strategy for biofuels. The potential bioconversion of carbohydrates in this potential resource, however, is limited by the associated aromatic constituents within the grass fiber. These aromatics include both lignins, which are phenylpropanoid units of various types, and low-molecular weight phenolic acids. Structural and chemical studies over the years have identified the location and limitation to fiber degradation imposed by a variety of these aromatic barriers. For example, coniferyl lignin appears to be the most effective limitation to biodegradation, existing in xylem cells of vascular tissues. On the other hand, cell walls with syringyl lignin, e.g., leaf sclerenchyma, are often less recalcitrant. Ferulic and p-coumaric acids that are esterified to hemicellulosic sugars constitute a major limitation to biodegradation in non-lignified cell walls in grass fibers, especially warm season species. Non-chemical methods to improve bioconversion of the lignocelluloses through modification of aromatics include: (1) use of lignin-degrading white rot fungi, (2) pretreatment with phenolic acid esterases, and (3) plant breeding to modify cell wall aromatics. In addition to increased availability of carbohydrates for fermentation, separation and collection of aromatics could provide value-added co-products to improve the economics of bioconversion.

Our model revealed that future hunting demand will likely decline in this region. Population growth in the region will increase demand, but structural change in the region's demography (e.g., "browning" and "aging"), along with declining forest-land access will decrease hunting demand. The results suggested that programs encouraging younger and non-white populations to participate in hunting could mitigate a forecast hunting decline in the region.

We apply a discrete duration model to estimate the effect of designated wilderness on the rate and timing of counties' economic transition in the Appalachian Region from 1969 to 2000. Transitions are measured as the year in which non-labor sources of income and services sector employment dominate the aggregate of resource extraction and manufacturing sectors as sources. Marginal effects and elasticities show designated wilderness had no practical effect on rates and timing of transition.

The genome of this spirochete contains a mitomycin C-inducible, prophage-like gene transfer agent designated VSH-1. VSH-1 particles package random 7.5-kb fragments of the B. hyodysenteriae genome and transfer genes between B. hyodysenteriae cells. The chemicals and conditions inducing VSH-1 production are largely unknown. Antibiotics used in swine management and stressors inducing traditional prophages might induce VSH-1 and thereby stimulate lateral gene transfer between B. hyodysenteriae cells. In these studies, VSH-1 induction was initially detected by a quantitative real-time reverse transcriptase PCR assay evaluating increased transcription of hvp38 (VSH-1 head protein gene). VSH-1 induction was confirmed by detecting VSH-1-associated 7.5-kb DNA and VSH-1 particles in B. hyodysenteriae cultures. Nine antibiotics (chlortetracycline, lincomycin, tylosin, tiamulin, virginiamycin, ampicillin, ceftriaxone, vancomycin, and florfenicol) at concentrations affecting B. hyodysenteriae growth did not induce VSH-1 production. By contrast, VSH-1 was detected in B. hyodysenteriae cultures treated with mitomycin C (10 kg/ml), carbadox (0.5 kg/ml), metronidazole (0.5 kg/ml), and H2O2 (300 kM). Carbadox- and metronidazole-induced VSH-1 particles transmitted tylosin and chloramphenicol resistance determinants between B. hyodysenteriae strains. The results of these studies suggest that certain antibiotics may induce the production of prophage or prophage-like elements by intestinal bacteria and thereby impact intestinal microbial ecology.

It highlights the synergy provided by applying what is known from forage digestibility and wheat and sorghum starch properties studies to the biofuels sector. Opportunities therefore, exist to improve biofuel qualities in these crops via genetics and agronomics. In contrast to cereal crops, switchgrass still retains tremendous exploitable genetic diversity, and can be specifically improved to fit a particular agronomic, management, and conversion platform. Combined with emerging studies on switchgrass genomics, conversion properties and management, the future for genetic modification of this species through conventional and molecular breeding strategies appear to be bright. The presence of brown-midrib mutations in sorghum that alter cell wall composition by reducing lignin and other attributes indicate that sorghum could serve as an important model species for C sub(4)-grasses. Utilization of the brown-midrib traits could lead to the development of forage and sweet sorghums as novel biomass crops. Additionally, wheat crop residue, and wheat and sorghum with improved starch content and composition represent alternate biofuel sources. However, the use of wheat starch as a biofuel is unlikely but its value as a model to study starch properties on biofuel yields holds significant promise.

Thus, we studied a Tifton loamy sand (fine-loamy, kaolinitic, thermic Plinthic Kandiudults) in Georgia, which is first in peanut production in USA, after 5 and 8years under continuous cotton (Gossypium hirsutum, L) (CtCtCt), cotton-cotton-peanut (CtCtPt), corn (Zea mays L.)-peanut-cotton (CrPtCt), peanut-peanut-cotton (PtPtCt), and continuous peanut (PtPtPt). Soil organic carbon (OC) at 0-20cm was already higher under PtPtPt (average, 8.7g C kg super(-1) soil), PtPtCt (average, 7.7g C kg super(-1) soil), and CrPtCt (average, 7.8g C kg super(-1) soil) compared with CtCtPt (average, 4.7g C kg super(-1) soil) and CtCtCt (average, 3.3g C kg super(-1) soil). Similarly, alkaline phosphatase, acid phosphatase, and phosphodiesterase as a group showed higher activities under PtPtPt, PtPtCt, and CrPtCt than under CtCtPt and CtCtCt. The activities of glycosidases (a-galactosidase, b-glucosidase, and b-glucosaminidase) as a group were more sensitive to the cropping systems than phosphastases and showed a distinctive cropping system separation as follows: PtPtPt=CrPtCt>PtPtCt>CtCtPt>CtCtCt. Similar to OC and microbial biomass C trends, distinctive differences were found in the microbial community structure of this sandy soil after 8years between peanut-based cropping systems (CrPtCt, PtPtCt, and PtPtPt) and cotton-based cropping systems (CtCtCt and CtCtPt) as indicated by the fatty acid methyl esters profiles.

PRSV isolates belong to either one of two major strains, P or W. The P strains infect both papaya and cucurbits whereas the W strains infect only cucurbits. Geographical distribution:PRSV-P is found in all major papaya-growing areas. Physical properties:Virions are filamentous, non-enveloped and flexuous measuring 760-80012nm. Virus particles contain 94.5% protein and 5.5% nucleic acid. The protein component consists of the virus coat protein (CP), which has a molecular weight of about 36kDa as estimated by Western blot analysis. Density of the sedimenting component in purified PRSV preparations is 1.32g/cm3 in CsCl. Genome:The PRSV genome consists of a unipartite linear single-stranded positive sense RNA of 10326 nucleotides with a 5' terminus, genome-linked protein, VPg. Transmission:The virus is naturally transmitted via aphids in a non-persistent manner. Both the CP and helper component (HC-Pro) are required for vector transmission. This virus can also be transmitted mechanically, and is typically not seed-transmitted. Hosts:PRSV has a limited number of hosts belonging to the families Caricaceae, Chenopodiaceae and Cucurbitaceae. Propagation hosts are: Carica papaya, Cucurbita pepo and Cucumis metuliferus cv. accession 2459. Local lesion assay hosts are: Chenopodium quinoa and Chenopodium amaranticolor. Control:Two transgenic papaya varieties, Rainbow and SunUp, with engineered resistance to PRSV have been commercially grown in Hawaii since 1998. Besides transgenic resistance, tolerant varieties, cross-protection and other cultural practices such as isolation and rogueing of infected plants are used to manage the disease.

Since that time, the measurement network has evolved to include measurement structures on 11 large watersheds (2.27-149 km super(2)), 8 medium watersheds (0.35-1.60 km super(2)), and 11 small watersheds (0.0018-0.59 km super(2)). The ephemeral nature of runoff, high-flow velocities, and high-sediment concentrations in the flow led to the development of the Walnut Gulch supercritical flume used on the large watersheds and the Smith supercritical flume used on the small watersheds. The period of record considered good to excellent ranges from 26 to 47 years. In 1999, the original analog recording systems were augmented with digital recorders. Runoff occurs at Walnut Gulch primarily as a result of convective thunderstorms during the months of July through September. Runoff volume and flow duration are correlated with drainage area as a result of the limited areal extent of runoff producing rainfall and transmission losses or infiltration of the flood wave into the channel alluvium. Runoff records including hydrographs and summary data are available in several formats via a Web interface at http://www.tucson.ars.ag.gov/dap/.

The lettuce samples were treated with gamma radiation to 0, 1 or 2kGy while maintaining a refrigerated temperature (4C). The samples were analyzed for total aerobic, total coliform and Enterobacteriaceae counts after refrigerated storage up to 12 days. No difference in aerobic counts was observed between the hot- and cold-washed samples immediately after washing. The coliform and Enterobacteriaceae counts were reduced by 2 log after the warm water wash and no difference for the cold water-washed sample. The irradiation treatment at 1kGy reduced the aerobic, coliform and Enterobacteriaceae counts by 2 log for the warm-washed samples. At the 2-kGy treatment level, the aerobic and coliform counts were reduced by 3 log for the cold-washed lettuce, whereas the Enterobacteriaceae counts were reduced by only 2 log. The observed log reductions in bacterial counts after irradiation were maintained for 12 days when stored at 4C. The combination of a cold water wash and irradiation to 2kGy had the best microbial keeping quality. Fresh-cut lettuce, when washed in either cold or warm water, shows neither an appreciable removal of the microbial load nor a significant increase in the keeping quality when compared with unwashed fresh-cut controls. Placing the washed lettuce into modified atmosphere packaging (MAP) did not lessen the overall bacteriologic load, and after 12 days of storage at 4C, the microbial counts increased. However, gamma irradiation of the washed, MAP-stored lettuce to a dose of 2kGy significantly reduces the overall microbe count, thereby increasing both the shelf life and the safety of the produce. A 2-kGy dose of gamma irradiation provides a pathogen-free, long shelf life, fresh-cut lettuce that is bacteriologically safer and sensorially indistinguishable from bagged, nonirradiated, fresh-cut lettuce.

Historically, Campylobacter fetus subsp. fetus was the major cause of Campylobacter-associated abortion in sheep; however, Campylobacter jejuni is increasingly associated with sheep abortions. We examined the species distribution, genotypes, and antimicrobial susceptibilities of abortion-associated Campylobacter isolates obtained from multiple lambing seasons on different farms in Iowa, Idaho, South Dakota, and California. We found that C. jejuni has replaced C. fetus as the predominant Campylobacter species causing sheep abortion in the United States. Most strikingly, the vast majority (66 of 71) of the C. jejuni isolates associated with sheep abortion belong to a single genetic clone, as determined by pulsed-field gel electrophoresis, multilocus sequence typing, and cmp gene (encoding the major outer membrane protein) sequence typing. The in vitro antimicrobial susceptibilities of these isolates to the antibiotics that are routinely used in food animal production were determined using the agar dilution test. All of the 74 isolates were susceptible to tilmicosin, florfenicol, tulathromycin, and enrofloxacin, and 97% were sensitive to tylosin. However, all were resistant to tetracyclines, the only antibiotics currently approved in the United States for the treatment of Campylobacter abortion in sheep. This finding suggests that feeding tetracycline for the prevention of Campylobacter abortions is ineffective and that other antibiotics should be used for the treatment of sheep abortions in the United States. Together, these results indicate that a single tetracycline-resistant C. jejuni clone has emerged as the major cause of Campylobacter-associated sheep abortion in the United States.

Polymorphic microsatellite loci for this beetle species will help map this continuing range expansion, and will also prove useful for exploring the mating system and local gene flow patterns for this important parasite. We describe 15 loci that are polymorphic in both the native and introduced ranges of this species, showing from two to 22 alleles.

TTP expression is reduced in fats of obese people with metabolic syndrome and brains of suicide victims and is induced by insulin and cinnamon polyphenol extract (CPE) in adipocytes, by lipopolysaccharide (LPS) in macrophages, and by green tea polyphenol extract in rats. CPE was reported to improve immune function against microorganisms, but the mechanism is unknown. This study tested the hypothesis that CPE regulates immune function involving genes encoding TTP, proinflammatory cytokines, and glucose transporter (GLUT) families and compared the effects of CPE to those of insulin and LPS in mouse RAW264.7 macrophages. CPE increased TTP mRNA and protein levels, but its effects were less than LPS. CPE (100 mg/L, 0.5-4 h) increased TTP and tumor necrosis factor (TNF) mRNA levels by up to 2- and 6-fold that of the control, respectively, and the base level of TTP was 6-fold that of TNF. LPS (0.1 mg/L, 4 h) increased TTP, TNF, granulocyte-macrophage colony-stimulating factor, cyclooxgenase-2, and interleukin 6 mRNA levels by 39-1868 fold. CPE and LPS increased GLUT1 expression (the major GLUT form in macrophages) to 3- and 2-fold that of the control, respectively. Insulin (100 nmol/L, 0.5-4 h) did not exhibit major effects on the expression of these genes. CPE increased TTP expression more rapidly than those of proinflammatory cytokines and the net increases of TTP mRNA levels were larger than those of proinflammatory cytokines. These results suggest that CPE can affect immune responses by regulating anti- and proinflammatory and GLUT gene expression.

Mathematical models, after extensive calibration and validation, are useful to derive such knowledge and to identify site-specific alternative agricultural management practices. A spatial-process model that uses GIS and ADAPT, a field scale daily time-step continuous water table management model, was calibrated and validated for flow and nitrate-N discharges from a 365ha agricultural watershed in central Iowa, in the Midwestern United States. This watershed was monitored for nitrate-N losses from 1991 to 1997. Spatial patterns in crops, topography, fertilizer applications and climate were used as input to drive the model. The first half of the monitored data was used for calibration and the other half was used in validation of the model. For the calibration period, the observed and predicted flow and nitrate-N discharges were in excellent agreement with r super(2) values of 0.88 and 0.74, respectively. During the validation period, the observed and predicted flow and nitrate-N discharges were in good agreement with r super(2) values of 0.71 and 0.50, respectively. For all 6 years of data, the observed annual nitrate-N losses of 26kgha super(-) super(1) for the entire simulation were in excellent agreement with predicted nitrate-N losses of 24.2kgha super(-) super(1). The calibrated model was used to investigate the long-term impacts of nitrate-N losses to changes in the rate and timing of fertilizer application. Results indicate that nitrate-N losses were sensitive to rate and timing of fertilizer application. Modeled annual nitrate-N losses showed a 17% reduction in nitrate-N losses by reducing the fertilizer application rate by 20% and switching the application timing from fall to spring. Further reductions in nitrate-N losses require conversion of row cropland to pasture and/or replacement of continuous corn or corn-soybean rotation systems with alternative crops.

Seven simulated grazing treatments were applied six years in eastern Montana, USA to determine effects on plant community composition and standing crop. Treatments were moderate stocking (28.8AUDha super(-) super(1)year super(-) super(1)) of cattle using 3-pasture summer rotation, season-long, high-intensity low-frequency, short-duration, 3-pasture winter rotation, and spring calving systems. The final treatment was severe growing-season grazing (108.2AUDha super(-) super(1)year super(-) super(1)). Treatments were randomly assigned to 14, 6.1-ha pastures. Post-treatment grass and total standing crops were 54 and 58% of their pre-treatment measures because of extended drought. No single grazing system affected standing crop of any herbage component. Standing crops of Pascopyrum smithii Rydb. (Love) (674+/-186kgha super(-) super(1); P>0.69), other perennial C sub(3) grasses (102+/-156kgha super(-) super(1); P>0.77), perennial C sub(4) grasses (178+ /-111kgha super(-) super(1); P>0.22), and shrubs (13+/-34kgha super(-) super(1); P>0.57) were similar across grazing treatments. Severe grazing produced more forbs (142+/-16kgha super(-) super(1); P<0.01) than moderate stocking (67+ /-16kgha super(-) super(1)). Annual C sub(3) grasses increased (P<0.01) from 131+ /-55kgha super(-) super(1) on pastures grazed after May to 362+/-55kgha super(-) super(1) on pastures grazed before June. Cacti also increased (P<0.03) from 47 to 187+/-52kgha super(-) super(1) on early-grazed pastures. Greater total standing crop on pastures grazed before June (P<0.03) was accounted for by increases in annual C sub(3) grasses and cacti. Rotational and continuous grazing strategies produced similar effects on all vegetation components. Grazing systems were not effective in altering standing crop or functional group composition one year after six years of treatment. Standing crop changes over time and limited shifts in forbs, cacti, and annual C sub(3) grasses indicate northern mixed prairie is most responsive to weather, with stocking rate and timing of grazing contributing minor influences.

In this regard, ingestion of small amounts of condensed quebracho tannin has been found to reduce N concentration in livestock urine. In this study, we sought to quantify the effects of tannin-affected cattle urine, normal cattle urine, and NH sub(4)NO sub(3) in solution on greenhouse gas flux. Carbon dioxide (CO sub(2)), methane (CH sub(4)), and nitrous oxide (N sub(2)O) flux was measured using static chamber methodology from the three N treatments and a no application control over a 6-week period in a mixed grass prairie in west-central North Dakota, USA. Over the course of the study, average CO sub(2) emission was greatest from normal urine (335+/-8mgCm super(-) super(2)h super(-) super(1)) and least from the control (229+/-19mgCm super(-) super(2)h super(-) super(1)), with intermediate fluxes for the tannin urine and NH sub(4)NO sub(3) treatments (290+/-27 and 286+ /-54mgCm super(-) super(2)h super(-) super(1), respectively). Methane uptake was prevalent throughout the study, as soil conditions were predominantly warm and dry. Uptake of CH sub(4) was greatest within the control (-30+ /-2 mu gCm super(-) super(2)h super(-) super(1)) and least in the tannin urine treatment (-12+ /-4 mu gCm super(-) super(2)h super(-) super(1)). Uptake of CH sub(4) was over 40% less within the tannin urine treatment as compared to normal urine, and may have been repressed by the capacity of tannin to bind monooxygenases responsible for CH sub(4) oxidation. Average N sub(2)O emission from NH sub(4)NO sub(3) solution was more than twice that of all other treatments. Though the tannin urine treatment possessed 34% less N than normal cattle urine, cumulative N sub(2)O emission between the treatments did not differ. Results from this study suggest the use of condensed quebracho tannin as a dietary amendment for livestock does not yield GHG mitigation benefits in the short-term.

Chemotaxis and chemokinesis were assayed in vitro using blind well chambers with peritoneal macrophages obtained from Nile tilapia, Oreochromis niloticus, 5days following squalene injection. Non-purified ECP derived from both isolates stimulated predominantly chemokinetic migration of macrophages. Additionally, the ECP were semi-purified by high pressure liquid chromatography. The FL6-60 parent ECP yielded higher molecular weight components than did the ECP from the RET-04 mutant. The chemotactic activity of the macrophages for both the FL6-60 parent and RET-04 mutant semi-purified ECP was increased over the non-purified ECP and overall migration was primarily chemotactic. Exposure to ECP derived from virulent and less virulent E. tarda isolates promoted chemokinetic movement of macrophages that may be involved in inflammatory responses of Nile tilapia to E. tarda infection.

To solve this problem, a new data structure based on dynamic arrays was designed and implemented in an algorithm that parses semi-ordered data made by Mascot, a separate software program that matches peptide tandem mass spectra to protein sequences in a database. By accommodating the special features of these large datasets, the combined dynamic array (CDA) provides efficient searching and insertion operations. The operations on real datasets using this new data structure are hundreds times faster than operations using binary tree and red-black tree structures. The difference becomes more significant when the dataset size grows. This data structure may be useful for improving the speed of other related types of protein assembling software or other types of software that operate on datasets with similar semi-ordered features.

Identifying and quantifying VSCs in air is challenging due to their volatility, reactivity, and low concentrations. In the present study, a canister-based method collected whole air in fused silica-lined (FSL) mini-canister (1.4L) following passage through a calcium chloride drying tube. Sampled air from the canisters was removed (10-600mL), dried, pre-concentrated, and cryofocused into a GC system with parallel detectors (mass spectrometer (MS) and pulsed flame photometric detector (PFPD)). The column effluent was split 20:1 between the MS and PFPD. The PFPD equimolar sulfur response enhanced quantitation and the location of sulfur peaks for mass spectral identity and quantitation. Limit of quantitation for the PFPD and MSD was set at the least sensitive VSC (hydrogen sulfide) and determined to be 177 and 28pgS, respectively, or 0.300 and 0.048 mu gm super(-) super(3) air, respectively. Storage stability of hydrogen sulfide and methanethiol was problematic in warm humid air (25 super(o)C, 96% relative humidity (RH)) without being dried first, however, stability in canisters dried was still only 65% after 24h of storage. Storage stability of hydrogen sulfide sampled in the field at a swine facility was over 2 days. The greater stability of field samples compared to laboratory samples was due to the lower temperature and RH of field samples compared to laboratory generated samples. Hydrogen sulfide was the dominant odorous VSCs detected at all swine facilities with methanethiol and dimethyl sulfide detected notably above their odor threshold values. The main odorous VSC detected in aged poultry litter was dimethyl trisulfide. Other VSCs above odor threshold values for poultry facilities were methanethiol and dimethyl sulfide.

(Malvaceae), squares of three sizes, and bolls of three ages to influence adult female boll weevil, Anthonomus grandisgrandis Boheman (Coleoptera: Curculionidae), longevity and egg production were evaluated in laboratory bioassays. While feeding on the reproductive portion of squares was expected to support adult boll weevils for considerable periods of time (e.g., medium square reproductive portion: approximately 185days), feeding on rinds also resulted in substantial longevity (e.g., medium square rind: approximately 120days). As anticipated, feeding on the reproductive portion of squares resulted in formation of chorionated eggs in mated females, but a diet comprised exclusively of rinds, particularly from large squares, was associated with gravidity and high fecundity relative to rinds of young and mature bolls. The reproductive portion and rind of post-bloom and young bolls as sources of food resulted in limited gravidity while mature bolls were not associated with any egg formation. These findings further our understanding of how boll weevils feed on different parts of the cotton plant and how those parts as food sources are related to the biology and ecology of the boll weevil.

This research characterized the temporal and spatial variability of litter ammonia (NH sub(3)) and nitrous oxide (N sub(2)O) flux via a chamber method, as well as determined litter nitrogen (N) compounds by intensive sampling in two commercial broiler houses on aged litter. Thirty-six grid samples were taken during a winter flock in Mississippi on days 2, 22, and 45. On day 45, eight additional samples were taken near the feeders and waterers (F/W). Geostatistical contour plots indicate NH sub(3) flux on day 2 was elevated in the brood area of house one (H1) where litter and air temperatures were highest; a commercial litter treatment held the NH sub(3) flux near zero for approximately 45% of the brood area in house two (H2). Day 45 NH sub(3) fluxes were similar, averaging 694mgm super(-) super(2)h super(-) super(1) in H1 vs. 644mgm super(-) super(2)h super(-) super(1) in H2; both houses exhibited greater NH sub(3) flux near the cooling pads. Ammonia flux, litter moisture and pH were diminished at the F/W locations. Heavy cake near the exhaust fans provided the lowest recorded litter pH, highest litter moisture and ammonium (NH sub(4)) with no NH sub(3) flux at the flock's end. Trends in litter condition based on bird activity were evident, but individual differences persisted between the houses. The importance of cake formation over the litter surface and differences based on location, both related to bird activity and house structure, should be considered in NH sub(3) mitigation strategies.

AN - 20687702; 8163124 AB - Water movement from roots to soil at night in the process of hydraulic lift (redistribution) rehydrates the rhizosphere and has been proposed to improve plant nutrient acquisition. Another process that has now been found in many plant species is nighttime transpiration and this could also affect nutrient relations by influencing supply of mobile nutrients to roots at night. The effects of these soil/root water relations interactions have not been adequately tested. We chose ten Sarcobatus vermiculatus (Hook.) Torrey shrubs with different magnitudes of hydraulic lift (i.e. diel range in soil water potential) to test the hypothesis that the magnitude of lift would be positively related to the amount of nitrogen (N) uptake over a period of days. A super(15)N tracer was injected in the 20-30 cm soil layer at locations with hydraulic lift to determine plant super(15)N acquisition by shallow roots conducting hydraulic lift. Half of the plants were also placed in large humidified tents (i.e. 'bagged'), which suppressed nighttime transpiration, and thus were expected to have greater magnitudes of hydraulic lift, although they did not. All plants took up the super(15)N tracer, but contrary to our hypothesis the magnitude of hydraulic lift had no significant effect on the amount of super(15)N acquired over a 9-day period following labeling. However, plants that were bagged tended to have lower super(15)N acquisition (P = 0.07). These data indicate that decreased nighttime transpirational water loss or some other effect of bagging may decrease nutrient acquisition by these nutrient-limited phreatophytic shrubs and more generally suggests a possible nutritional benefit of nighttime transpiration by plants. This suggestion needs more thorough testing to elucidate an important potential link between plant water and nutrient relations.

However, the hydraulic resistance of leaves can be highly variable over short time scales, uncoupling tension in the xylem of leaves from that in the stems to which they are attached. We evaluated a suite of leaf and stem functional traits governing water relations in individuals of 11 lowland tropical forest tree species to determine the manner in which the traits were coordinated with stem xylem vulnerability to embolism. Stomatal regulation of psi sub(L) was associated with minimum values of water potential in branches ( psi sub(br)) whose functional significance was similar across species. Minimum values of psi sub(br) coincided with the bulk sapwood tissue osmotic potential at zero turgor derived from pressure-volume curves and with the transition from a linear to exponential increase in xylem embolism with increasing sapwood water deficits. Branch xylem pressure corresponding to 50% loss of hydraulic conductivity (P sub(50)) declined linearly with daily minimum psi sub(br) in a manner that caused the difference between psi sub(br) and P sub(50) to increase from 0.4 MPa in the species with the least negative psi sub(br) to 1.2 MPa in the species with the most negative psi sub(br). Both branch P sub(50) and minimum psi sub(br) increased linearly with sapwood capacitance (C) such that the difference between psi sub(br) and P sub(50), an estimate of the safety margin for avoiding runaway embolism, decreased with increasing sapwood C. The results implied a trade-off between maximizing water transport and minimizing the risk of xylem embolism, suggesting a prominent role for the buffering effect of C in preserving the integrity of xylem water transport. At the whole-tree level, discharge and recharge of internal C appeared to generate variations in apparent leaf-specific conductance to which stomata respond dynamically.

While the longevity and fecundity of parasitoids are positively affected by nectar subsidies in laboratory studies, the impacts of floral subsidies on the fecundity and longevity of freely foraging parasitoids have not been studied.We studied the longevity and per capita fecundity of naturally occurring Diadegma insulare foraging in cabbage plots with and without borders of flowering buckwheat, Fagopyrum esculentum, as well as relationships between longevity, fecundity, sugar feeding and parasitism rates on larvae of the diamondback moth, Plutella xylostella.Relative longevity was estimated by counting broken setae on the fringe of the forewing. Floral borders increased the longevity of males and females in adjacent cabbage plots.The egg maturation rate of D. insulare was estimated by comparing egg loads of females collected early in the day with egg loads of females held without hosts in field cages throughout the day. Females in buckwheat cages matured 2.7 eggs per hour while females in control cages resorbed 0.27 eggs over the same time period.The fecundity of females collected in the afternoon was estimated by comparing their actual egg load to the estimated egg load in the absence of oviposition for females in a given plot. Females foraging in buckwheat plots had marginally fewer eggs remaining in their ovaries, and laid marginally more eggs than females in control plots. Females from both treatments carried 30-60 eggs by the afternoon and therefore were time-limited rather than egg-limited.Plots where a greater proportion of females had fed on sugar had longer-lived females. This suggests that feeding enhanced longevity of D. insulare. However, plots with longer-lived and more fecund females did not exhibit higher parasitism rates, although the power of these tests were low.

Diseased rambutan fruit was commonly observed in orchards in the Hilo and Kona districts of Hawaii Island during 2006. In surveys conducted in January, symptoms appeared as dark brown-to-black spots on mature fruit and blackened areas at the base of spinterns (hair-like projections) of mature and immature fruits. Pieces of infected fruit (cv. R167) were surface sterilized for 2 min in 0.5% NaOCl, plated on potato dextrose agar, and incubated at 24 plus or minus 1 degree C for 7 days. The fungus growing on PDA was pale buff with sparse, aerial mycelium and acervuli containing black, slimy spore masses. All isolates had five-celled conidia. Apical and basal cells were hyaline, while the three median cells were olivaceous; the upper two were slightly darker than the lower one. Conidia (n = 40) were 20.3 plus or minus 0.1 x 6.8 plus or minus 0.1 mu m. There were typically three apical appendages averaging 16.8 plus or minus 0.2 mu m long. The average basal appendage was 3.8 plus or minus 0.1 mu m long. The fungus was initially identified as Pestalotiopsis virgatula (Kleb.) Stey. on the basis of conidial and cultural characteristics. The identification was confirmed by molecular analysis of the 5.8S subunit and flanking internal transcribed spacers (ITS1 and ITS2) of rDNA amplified from DNA extracted from single-spore cultures with the ITS1/ITS4 primers and sequenced (GenBank Accession No. EU047943). To confirm pathogenicity, agar pieces, 3 mm in diameter, from 7-day old cultures were used as inoculum. Five mature fruit from rambutan cv. R134 were rinsed with tap water, surface sterilized with 0.5% NaOCI for 2 min, wounded with a needle head, inoculated in the laboratory, and maintained in a moist chamber for 7 days. Lesions resembling symptoms that occurred in the field were observed on fruit after 7 days. No symptoms were observed on fruit inoculated with agar media. The fungus reisolated from diseased fruit was identical to the original isolates, confirming Koch's postulates. The disease appears to be widespread in Hawaii. Preharvest symptoms may have the potential to affect postharvest fruit quality if fruits are not stored at the proper conditions. Pestalotiopsis spp. have been reported on rambutan in Malaysia, Brunei, and Australia. To my knowledge, this is the first report of P. virgatula causing fruit spots on rambutan in Hawaii.

The pathogen has been reported to occur on more than 90 legume species worldwide and it is likely to infect native and introduced legume species in the United States. The objective of this study was to determine if 176 species representing 57 genera of legumes, the majority of which are either native or naturalized to soybean-growing areas of the United States, could be hosts of P. pachyrhizi. Between one and three accessions of each species, a total of 264 accessions, were inoculated with a mixture of four isolates of P. pachyrhizi. Severity and sporulation were rated on a 1-to-5 scale at 14 and 28 days after inoculation. P. pachyrhizi was confirmed by the presence of sporulating uredinia and/or immunological assay on 65 new species in 25 genera; 12 of these genera have not been reported previously as hosts. Many of the newly identified hosts grow in the southern United States, and like kudzu, could serve as overwintering hosts for P. pachyrhizi.

The amidation reactions were catalyzed by immobilized Pseudozyma (Candida) antarctica lipase B (Novozym 435) in organic solvent with ammonium carbamate. The mass spectra of the underivatized products exhibited characteristic primary amide peaks at m/z 59 and m/z 72 that differed in peak intensities. Other peaks present were consistent with cleavage next to the hydroxyl groups. The mass spectra of the silylated amidation products showed the correct molecular weight and the typical fragmentation pattern of silylated hydroxy compounds. The mass spectra, together with proton and super(13)C NMR data, suggest that the products of lipase-catalyzed direct amidation of 7,10-dihydroxy-8(E)-octadecenoic acid and 7,10,12-trihydroxy-8(E)-octadecenoic acid are, 7,10-dihydroxy- 8(E)-octadecenamide and 7,10,12-trihydroxy-8(E)-octadecenamide acid, respectively. Amidation of multi-hydroxylated fatty acids had increased the melting point, but reduced the surface active property of the resulting primary amides.

Wetlands can be used to physically remove compounds such as suspended solids through sedimentation. Dissolved nutrients, biochemical oxygen demand, heavy metals, and potentially harmful anthropogenic compounds can all be removed in constructed wetlands through geochemical and biological processes. Sample collection to evaluate the effectiveness of treatment and to monitor the status of wetlands is usually only conducted at the inlet and outlet of the wetland due to cost constraints. To better understand the internal hydrology and biogeochemical processes operating within the wetland more intensive sampling is needed that does not interfere with the hydraulics of the system. A new relatively low-cost sample collection design has been developed using mostly off-the-shelf parts that allows for permanent, internal, three-dimensional sample collection in wetlands. The design has been used to construct a permanent three-dimensional array of 60-sample locations that can be sampled simultaneously throughout a 1.2ha constructed wetland for less than US$ 5000. The sampling array was used in a tracer study and showed spatial and temporal differences in tracer concentration within the wetland. Concentration differences were seen and measured in all three dimensions.

In this study, we isolated the enhancer element of ArabidopsisAGAMOUS that drives gene expression specifically in stamens and carpels. By fusing this AG enhancer to a minimal 35S promoter fragment, two tissue-specific promoters, fAGIP and rAGIP in forward and reverse orientations, respectively, were created and fused to the GUS reporter. Transgenic Arabidopsis plants harboring either fAGIP::GUS or rAGIP::GUS displayed similar GUS expression specifically in carpel and stamen tissues and their primordial cells. To test their utility for engineering sterility, the promoters were fused to the Diphtheria toxin A (DT-A) gene coding for a ribosome inactivating protein as well as the Barnase gene coding for an extracellular ribonuclease, and tested for tissue-specific ablation. Over 89% of AGIP::DT-A and 68% of AGIP::Barnase transgenic plants displayed specific and precise ablation of stamens and carpels and are completely sterile. These transgenic plants showed normal vegetative development with prolonged vegetative growth. To evaluate the stability of the sterile phenotype, 16 AGIP::DT-A lines underwent two consecutive cutback generations and showed no reversion of the floral phenotype. This study demonstrates a simple, precise and efficient approach to achieve absolute sterility through irreversible ablation of both male and female floral organs. This approach should have a practical application for transgene containment in ornamental, landscaping, and woody species, whose seeds and fruits are of no economic value.

PAM degradation has not directly been measured in soil. We tested the ability of stable isotopes of C and N at natural abundance to estimate PAM degradation rates. Values of delta super(13)C were related to anionic PAM concentration in a positive curvilinear relationship in a low-C, low-N, Durinodic Xeric Haplocalcid (Portneuf series) soil. The other soils with higher organic C or N concentrations did not show significant relationships between PAM concentrations and delta super(13)C values. The delta super(15)N values were not related to anionic PAM concentration in any of the soils tested. When 2691 active ingredient (ai) kg PAM ha super(- 1) was applied to the Durinodic Xeric Haplocalcid soil, 49% and 74% of the PAM was degraded after 6 and 12 yr respectively. When 5382 kg ai PAM ha super(- 1) was applied to the Durinodic Xeric Haplocalcid soil, 13% was degraded after 6 yr, and 73% of the PAM was degraded after 12 yr. We calculated PAM degradation rate based on delta super(13)Cfor the Durinodic Xeric Haplocalcid soil to be 9.8% yr super(- 1). Further testing using labeled PAM is necessary to estimate degradation rates in higher C soils, and to determine what portion of the C is released from decomposing PAM is emitted to the atmosphere, incorporated into soil organic matter and living microbial biomass.

New strategies to include chemical repellents are needed to mitigate crop losses. We evaluated 3 preplant seed treatments (Apron XL+ LS [Syngenta Crop Protection, Greensboro, NC], Dividend Extreme+ [Syngenta], and Maxim+ 4 FS [Syngenta]), one foliar insecticide (Karate+ with Zeon Technology+ [Syngenta]), and one foliar fungicide (Tilt+ [Syngenta]) as potential blackbird repellents in caged feeding trials and a field study. For all repellents tested, red-winged blackbirds (Agelaius phoeniceus) discriminated between untreated and treated rice during preference testing in captivity. We observed a positive concentration-response relationship among birds offered rice treated with 25%, 50%, 75%, 100%, or 200% of the manufacturer label for Dividend Extreme, Karate, and Tilt. Relative to pretreatment, blackbirds ate 32% and 69% less rice treated with 100% and 200% Tilt label rates, respectively, during the concentration-response test. Maximum repellency of Dividend Extreme and Karate was 55% at 200% of their label rates. We observed no repellency of a combination of Apron and Maxim at 25-200% label rates during the concentration-response test. We subsequently measured rice crop consumption and propiconazole (active ingredient, Tilt) residues among 10 plots (i.e., netted enclosures) populated with red-winged blackbirds within a maturing rice field. Average mass of rice harvested between treated (Tilt) and untreated subplots did not differ. We recovered an average of 12.3 kg/g propiconazole immediately following the first application and 20.2 kg/g propiconazole immediately following the second application of Tilt. We recovered <0.1 kg/g propiconazole on 15 August 2006, just before populating plots with blackbirds. Thus, the label application of Tilt fungicide did not reduce blackbird consumption within a maturing rice field, and residues of the active ingredient were insufficient for repellent efficacy. Additional studies are needed to determine whether higher concentrations of Tilt repel blackbirds under field conditions and to evaluate other potential repellents for protection of newly planted and ripening crops.

Primers designed from a pairwise alignment of genomic sequences of CTLV isolates from lily and from kumquat amplified two nonoverlapping genomic regions of 625 and 1,165 bp (approximately 28% of the CTLV genome) which were cloned and sequenced. Despite being propagated separately in the glasshouse for more than 40 years, the CTLV sequences from separate Meyer lemon sources were identical but had only approximately 80% nucleotide identity with the homologous regions of CTLV genomes of isolates from lily and kumquat. Neighbor-joining phylogenetic analysis indicated the CTLV isolates from Meyer lemon were distinct from but more closely related to CTLV from kumquat than from lily, and these CTLV sequences showed equivalent genetic distances from two ASGV isolates.

To assess their role in mitochondrial and cellular functions in the pathogenic yeast Candida glabrata, a functional characterization of the CgPGS1 gene encoding the phosphatidylglycerolphosphate synthase has been carried out. Transposon insertion mutation in CgPGS1 resulted in the loss of phosphatidylglycerolphosphate synthase activity and in deficiency of both phosphatidylglycerol and cardiolipin. The Cgpgs1 Delta mutant cells displayed reduced amounts of cytochrome b and cytochrome a, and had impaired growth on minimal media containing non-fermentable carbon and energy sources. They did not grow at elevated temperatures and failed to form colonies after induction of mitochondrial DNA deletions. The mutant cells also displayed a decreased susceptibility to fluconazole, ketoconazole, clotrimazole, voriconazole and posaconazole. In the Cgpgs1 Delta mutant, a quantitative real time PCR revealed enhanced mRNA levels for multidrug resistance associated genes such as CgPDR1 encoding transcriptional activator and CgCDR1, CgPDH1 and CgSNQ2 coding for drug efflux transporters. These results indicate that CgPGS1 and anionic phospholipids are required for optimal mitochondrial functions and maintenance of yeast susceptibility to azole antifungals.

The disease is associated with three different species of fastidious a-proteobacteria, namely 'Candidatus Liberibacter asiaticus', Ca. L. americanus, and Ca. L. africanus. 'Ca. L. asiaticus' was first detected in South Florida in 2005 and has spread throughout the citrus-growing areas of Florida. 'Ca. L. asiaticus' is transmitted naturally by the Asian citrus psyllid, Diaphorina citri, and can also be transmitted by graft propagation and via various species of dodder (Cuscuta). HLB affects most if not all citrus and citrus relatives within the family Rutaceae, including the ornamental shrub Murraya paniculata. In addition, 'Ca. L. asiaticus' and 'Ca, L. americanus' can infect tobacco (Nicotiana xanthi) and periwinkle (Catharanthus roseus). Here we report that `Ca. L. asiaticus' can infect tomato (Lycopersicon esculentum) cvs. Manapal and FL47. Manapal and FL 47 plants grown from seed were placed adjacent to 'Ca. L. asiaticus'-infected sweet orange (Citrus sinensis) plants with dodder (Cuscuta pentagona) already well established on them. Young dodder shoots still connected to the citrus were draped over the tomato plants and subsequently also became attached to the tomato stems. After 1 month, the tomato plants were detached from the citrus and most of the dodder removed. One month later, these tomato plants started to show vein clearing and subsequently the mature leaves became thicker and leathery. Some leaves showed blotchy mottle symptoms and some fruits became lopsided in a manner similar to HLB symptom expression on citrus. PCR amplification of the 'Ca. L. asiaticus' 16S rDNA with primers OI1/OI2c and the P-operon with primers A2/J5 revealed the presence of 'Ca. L. asiaticus' DNA. Sequence analysis confirmed that the sequences of the cloned am-plicons were identical to those from the HLB-infected citrus source plant. Both conventional and quantitative real-time PCR revealed a much lower abundance of 'Ca. L. asiaticus' DNA in tomato as compared with 'Ca. L. asiaticus'-infected citrus or periwinkle, indicating that 'Ca. L. asiaticus' bacteria multiplied at a lower titer in these tomato cultivars.

In this study, a combination of traditional polymerase chain reaction (PCR) and real-time PCR targeting the putative DNA polymerase and 16S rDNA sequence of 'Candidatus Liberibacter asiaticus,' respectively, were used to examine the distribution and movement of the HLB pathogen in the infected citrus tree. We found that 'Ca. Liberibacter asiaticus' was distributed in bark tissue, leaf midrib, roots, and different floral and fruit parts, but not in endosperm and embryo, of infected citrus trees. Quantification analysis of the HLB bacterium indicated that it was distributed unevenly in planta and ranged from 14 to 137,031 cells/ug of total DNA in different tissues. A relatively high concentration of 'Co. Liberibacter asiaticus' was observed in fruit peduncles. Our data from greenhouse-infected plants also indicated that 'Ca. Liberibacter asiaticus' was transmitted systemically from infection site to different parts of the plant. Understanding the distribution and movement of the HLB bacterium inside an individual citrus tree is critical for discerning its virulence mechanism and to develop management strategies for HLB.

First, a laboratory incubation to quantify broiler litter N mineralization with the following treatments: two soil moisture regimes, constant at 60% water fill pore space (WFPS) and fluctuating (60-30% WFPS), three soil types, Brooksville silty clay loam, Ruston sandy loam from Mississippi, and Catlin silt loam from Illinois. Second, a field incubation study to quantify broiler litter N mineralization using similar soils and litter application rates as the laboratory incubation. Broiler litter was applied at an equivalent rate of 350 kg total N ha super(-1) for both studies except for control treatments. Subsamples were taken at different timing for both experiments for NO sub(3)-N and NH sub(4)-N determinations. In the laboratory experiment, soil moisture regimes had no significant impact on litter-derived inorganic N. Total litter-derived inorganic N across all treatments increased from 23 mg kg super(- 1) at time 0, to 159 mg kg super(-1) at 93 d after litter application. Significant differences were observed among the soil types. Net litter- derived inorganic N was greater for Brooksville followed by Ruston and Catlin soils. For both studies and all soils, NH sub(4)-N content decreased while NO sub(3)-N content increased indicating a rapid nitrification of the mineralized litter N. Litter mineralization in the field study followed the same trend as the laboratory study but resulted in much lower net inorganic N, presumably due to environmental conditions such as precipitation and temperature, which may have resulted in more denitrification and immobilization of mineralized litter N. Litter-derived inorganic N from the field study was greater for Ruston than Brooksville. Due to no impact by soil moisture regimes, additional studies are warranted in order to develop predictive relationships to quantify broiler litter N availability.

The adequacy of such soil tests for this purpose is commonly assessed through a comparison of extraction results with metal contents in relevant plants. In this work, the fractions of selected risk metals (Al, As, Cd, Cu, Fe, Mn, Ni, Pb, Zn) that can be taken up by various plants were obtained by optimized BCR (Community Bureau of Reference) three-step sequential extraction procedure (SEP) and by single 0.5 mol L super(-1) HCl extraction. These procedures were validated using five soil and sediment reference materials (SRM 2710, SRM 2711, CRM 483, CRM 701, SRM RTH 912) and applied to significantly different acidified soils for the fractionation of studied metals. The new indicative values of Al, Cd, Cu, Fe, Mn, P, Pb and Zn fractional concentrations for these reference materials were obtained by the dilute HCl single extraction. The influence of various soil genesis, content of essential elements (Ca, Mg, K, P) and different anthropogenic sources of acidification on extraction yields of individual risk metal fractions was investigated. The concentrations of studied elements were determined by atomic spectrometry methods (flame, graphite furnace and hydride generation atomic absorption spectrometry and inductively coupled plasma optical emission spectrometry). It can be concluded that the data of extraction yields from first BCR SEP acid extractable step and soil-plant transfer coefficients can be applied to the prediction of qualitative mobility of selected risk metals in different soil systems.

We focus, in particular, on several key questions: Has benefit-cost targeting increased the environmental benefit obtained from program budgets? Has competitive bidding reduced program costs? To what extent have these program designs resulted in additional gain (that would not have otherwise been obtained)? Previous research illustrates how benefit-cost targeting using environmental indices (such as the Environmental Benefits Index in the Conservation Reserve Program) can increase environmental cost-effectiveness. Previous research and data from two U.S. programs suggests that bidding has reduced costs, but that the full potential of bidding may not have been realized. Finally, most U.S. programs are intended to yield environmental gains that would not have otherwise been obtained, but sometimes fall short of this goal.

This practice results in nutrient losses and potentially unfavorable environmental impacts particularly during the wet winter months. A field plot experiment was initiated in 2001 on a Ruston silt loam in Mize, MS to identify the proper BCL application timing that enhances BCL nutrient uptake by crops while minimizing undesirable nutrient buildup in soil. Seven treatments (BCL application timings) were employed on previously established 'Coastal' hybrid bermudagrass [Cynodon dactylon (L.) Pers.] plots. For each treatment, the quantity of broiler chicken litter (a mixture of chicken manure plus bedding materials) needed for each plot was calculated based on the BCL total N content to provide 400 kg N ha super(-1) for top bermudagrass yield (18 Mg ha super(-1)) and applied either as a single, two-way split, or three-way split at different dates as follow: May; May/June; April/May/June; May/June/July; June/July/August; July/August/September; and August/September/October. Bermudagrass was harvested 5 times each year for dry matter (DM) and nutrient uptake determination. Significant differences in DM yield were observed in each year among application timings. The greatest DM yield was 18.6 Mg ha super(-1 )for the single application in May and lowest at 15.0 Mg ha super(-1 )for Aug/Sep/Oct application dates in 2001 and followed by the same trend in 2002. The N and P uptake by bermudagrass ranged from 270 to 381, and 53 to 63 kg ha super(-1) respectively, in 2001. Similar trend, but lower values for nutrient uptake were observed in 2002. Significant differences were observed among BCL application timings in regard to soil residual of total carbon (TC), total nitogen (TN), Mehlich 3 extracted P (M3-P), NO sub(3)-N, Cu, and Fe elements at the end of the study. In general, summer and early fall BCL applications resulted in greater buildup of most of these elements. Based on the results of this study, there is a wide window (May-July) for BCL application timing on bermudagrass considering the criteria of producing high yield and low soil residual nutrient. However, the best BCL application timing should be in spring (late April-June) when minimum temperatures exceed those required (24-27 degree C) for bermudagrass growth.

We evaluated effects of topography (elevation, slope, and proximity of roads and streams), forest habitat class, and landscape patch configuration on selection of summer diurnal roosts by 6 species of forest-dwelling bats in a diverse forested landscape of the Ouachita Mountains, Arkansas, USA. Our objectives were to identify landscape attributes that potentially affect roost placement, determine whether commonalities exist among species in their response to landscape attributes, and evaluate the effects of scale. We modeled roost selection at 2 spatial scales (250- and 1,000-m radius around each roost). For each species, parameters included in models differed between the 2 scales, and there were no shared parameters for 2 species. Average coefficients of determination (R2) for small-scale models were generally higher than for large-scale models. Abundance of certain forest habitat classes were included more often than patch configuration or topography in differentiating roost from random locations, regardless of scale, and most species were more likely to roost in areas containing abundant thinned forest. Among topographic metrics, big brown bats (Eptesicus fuscus) were more likely to roost at higher elevations; roosts of big brown bats, northern long-eared bats (Myotis septentrionalis), and Seminole bats (Lasiurus seminolus) were influenced by slope; and big brown bats, evening bats (Nycticeius humeralis), and Seminole bats were more likely to roost closer to water than random. Northern long-eared bats and red bats (Lasiurus borealis) were more likely to roost closer to roads, whereas eastern pipistrelles (Perimyotis subflavus) were more likely to roost further from roads than random. Common parameters in most models included 1) positive associations with group selection (5 of 6 species) and thinned mature forest (4 species) at the small scale; 2) negative associations with unmanaged mixed pine-hardwood forest 50-99 years old at the large scale (4 species); 3) negative association with stands of immature pine 15-29 years old at the small scale (3 species); and 4) a positive association with largest patch index at the large scale (3 species). Our results suggest that, in a completely forested landscape, a variety of stand types, seral stages, and management conditions, varying in size and topographic location throughout the landscape, would likely provide the landscape components for roosting required to maintain a diverse community of forest bats in the Ouachita Mountains.

We evaluated the efficacy of systematic aerial and ground sampling protocols to detect stoekiing-rate differences across 130 ha of shortgrass prairie. Manual (SamplePoint) and automated (spectral) Image-analysis methods were compared for both aerial and ground data. Vegetative cover changes due to grazing were detectable from 1-mm ground sample distance (GSD. a measure of resolution) digital aerial photography with as few as 30 samples yielding enough data to predict bare ground within plus or minus 5%. We found poor agreement between automated and manual Image-analysis methods, but good agreement between manual analyses of imagery from the air (100 m above ground level [AGL]) and from the ground (2 m AOL). We conclude that cover measurements made using Sample Point from 1-mm GSD Images (from 2 or 100 m AGL) can detect ecologically important changes In key Indicators such as bare ground. The costs of ground and aerial methods differ markedly, and we suggest mat aerial imagery is most cost effective for areas larger than 200 ha.

The National Weather Service (NWS), Department of Defense, and Federal Aviation Administration operate a network of Doppler radar stations that produce hourly rainfall estimates, at approximately 16-km2 resolution, with nominal coverage of 96% of the conterminous United States. Internal utilization of these data by the three agencies is primarily for the detection and modeling of extreme weather events. The usefulness of these data for external hydrologic and natural resource applications is limited by a lack of tools for decoding and georeferencing digital precipitation data products. We modified NWS source code to produce decoding and georeferencing tools and used them to evaluate radar precipitation data for the Boise (CBX) radar relative to gauges in the Snake River Plain of southwestern Idaho for the period January 1998 to May 2004. The relationship between radar and gauge precipitation estimates changed after a revision of radar-processing protocols in 2002 and 2003. Cumulative radar precipitation estimates made prior to November 2002 underestimated gauge readings by 50%-60%. Subsequent radar data overestimated cumulative gauge precipitation by 20%-40%. The radar, however, detected precipitation during significantly fewer hours than were detected by the gauge network both before and after programming changes. Additional modification of NWS precipitation-processing procedures might improve accessibility and utility of these data for rangeland management and natural resource modeling applications. Currently available data can still be very useful for estimating high-intensity events that greatly affect processes such as soil erosion and flooding.

Existing shade assessment tools, however, are inadequate for monitoring extensive stream networks. Our objectives were to develop and evaluate an efficient, low-cost field technique for sampling stream-surface shading using digital images and to evaluate the efficiencies and effectiveness of eight different digital image analysis techniques for shade assessments. We developed a quadrat-based technique and associated field equipment to directly photograph stream-surface shading. Sampling at random points (pixels) within the resultant digital images was the most accurate, efficient, and robust image analysis technique. An approach pairing the photographic field technique and the random point-sampling image analysis technique should enable managers to conduct ground-based assessments of stream shading over extensive stream networks. This approach may also provide an efficient means of collecting ground truth samples for even broader scale, remote sensing-based stream-shade assessments.

A simultaneous equation model of 1990-2000 change in jobs and net migration indicates that landscape features influenced migration directly, not through effects on employment. An inordinate rise in housing values in the most highly scenic areas in 1990-2000 was associated with an exceptional slowing of migration to those areas in 2000-2005, an indication that housing supply constraints such as land use regulation may now be dampening the ties between landscape preferences and migration in rural areas. The study findings on current habitat selection are particularly interesting given the frequent conjecture that landscape preferences are adaptive, reflecting the most suitable habitats for early man.

Oak-dominated communities provide a multitude of human and natural resource values throughout the eastern United States, but their long-term sustainability is threatened throughout the region by poor regeneration. This study was established to assess regeneration following midstory thinning (late 2000) and prescribed fire application (2001 and 2005) at two sites in southern Ohio. Each of the four 20+ha treatment units (two thin and burn, two untreated controls) were modeled for long-term moisture regime using the integrated moisture index (IMI), and a 50m grid of sampling points was established throughout the units. Vegetation and canopy openness were sampled at each gridpoint before and after treatments, in 2000, 2001, 2004, and 2006. The thin and burn treatment generally resulted in more advance regeneration (>50cm height) of oak and hickory. The second fires in 2005 created additional landscape heterogeneity by causing variable tree mortality, and thus canopy openness, across the IMI gradient. The drier landscape positions generally had more intense fires, more canopy openness, and more oak and hickory advance regeneration; several other tree species also exhibited marked landscape variation in regeneration after treatments. Though advance regeneration of several competing species became abundant after the initial treatments, the second fires reduced the high densities of the two major competitors, Acer rubrum and Liriodendron tulipifera. Two simple models were developed: (1) a model of oak ''competitiveness'' based on the plot data related to advance regeneration of oaks and competitors and (2) a model estimating the probability of a plot becoming 'competitive for oak' based on canopy openness, IMI class, and number of oak and hickory seedlings present. For dry or intermediate sites with at least 5000 oak and hickory seedlings/ha, opening the canopy to 8.5-19% followed by at least two fires should promote oak and hickory to be 'competitive' over about 50% of the area. However, no appreciable oak and hickory regeneration developed on mesic sites. Overall, these results suggest promise for partial harvesting and repeated fires as a management strategy to reverse the accelerating loss of oak dominance in the central hardwoods region.

The technique is based on the link between spectral emissivities within the 8.5-9.5 mu m interval and density of sparsely covered terrains. The link exists regardless of plant color, which means that it is often possible to distinguish bare soils from senescent and non-green vegetation. This capability is typically not feasible with vegetation indices. The method is demonstrated and verified using ASTER remote sensing observations between 2001 and 2003 over the Jornada Experimental Range, a semi-arid site in southern New Mexico, USA. A compilation of 27 nearly cloud-free, multispectral thermal infrared scenes revealed spatially coherent patterns of spectral emissivities decreasing at rates on the order of 3% per year with R super(2) values of } .82. These patterns are interpreted as regions of decreased vegetation densities, a view supported by ground-based leaf area index transect data. The multi-year trend revealed by ASTER's 90-m resolution data are independently confirmed by 1-km data from Terra MODIS. Comparable NDVI images do not detect the long-term spatially coherent changes in vegetation. These results show that multispectral thermal infrared data, used in conjunction with visible and near infrared data, could be particularly valuable for monitoring land cover changes.

Current methods of measuring residue cover are inadequate for characterizing the spatial variability of residue cover over large fields. The objectives of this research were to determine the effects of water content on the remotely sensed estimates of crop residue cover and to propose a method to mitigate the effects of water content on remotely sensed estimates of crop residue cover. Reflectance spectra of crop residues and soils were measured in the lab over the 400-2400 nm wavelength region. Reflectance of scenes with various residue cover fractions and water contents was simulated using a linear mixture model. Additional spectra of scenes with mixtures of crop residues and soil were also acquired in corn, soybean, and wheat fields with different tillage treatments and different water content conditions. Crop residue cover was linearly related to the cellulose absorption index (CAI), which was defined as the relative intensity of an absorption feature near 2100 nm. Water in the crop residue significantly attenuated CAI and changed the slope of the residue cover vs. CAI relationship. Without an appropriate correction, crop residue covers were underestimated as scene water content increased. Spectral vegetation water indices were poorly related to changes in the water contents of crop residues and soils. A new reflectance ratio water index that used the two bands located on the shoulders of the cellulose absorption feature to estimate scene water conditions was proposed and tested with data from corn, soybean, and wheat fields. The ratio water index was used to describe the changes in the slope of crop residue cover vs. CAI and improve the predictions of crop residue cover. These results indicate that spatial and temporal adjustments in the spectral estimates of crop residue cover are possible. Current mutispectral imaging systems will not provide reliable estimates of crop residue cover when scene water content varies. Hyperspectral data are not required, because the three narrow bands that are used for both CAI and the scene moisture correction could be incorporated in advanced multispectral sensors. Thus, regional surveys of soil conservation practices that affect soil carbon dynamics may be feasible using either advanced multispectral or hyperspectral imaging systems.

Resulting even-age stands are gradually colonized by other plant species, but understory structure is poorly quantified, and the effects of management on understory vegetation are unknown. We examined the structure of the dominant understory species 23 years after stand initiation and determined their subsequent 2-year growth responses to silvicultural treatments prescribed to improve growth of koa. Release thinning, chemical control of introduced grasses, and phosphorus fertilization were applied in a split-plot experimental design. Results for DBH and height class distributions indicated that recruitment for most tree species began within a few years of stand initiation. By 23 years understory trees made up only 14% of total stand basal area, but they added greatly to native plant biodiversity. Alien grasses covered 92% of the forest floor and averaged 1.35Mgha super(-) super(1). Of the four most abundant native understory tree species, only shade intolerant Myoporum sandwicense grew faster in response to the treatments. P-fertilizer combined with grass control significantly increased production of the native shrub, Rubus hawaiiensis. Notably, alien grass biomass did not increase in response to thinning, and actually declined in P-fertilized plots. Only, where P-fertilizer was applied were P concentrations of understory leaves elevated. Foliar concentrations of other nutrients were generally unaffected by treatments. Our findings suggest that the conservative silvicultural treatments we used can be applied without adversely impacting the capacity of aggrading A. koa forests to support a diversity of native understory plants. Lack of an increase in alien grass biomass, and in the case of P fertilization, a reduction in grass biomass, indicates that treatments should not increase competition with native species.

Animals--36 weanling Boer-Spanish goats. Procedures--6 goats were allocated to each of 2 M ramosissimus-inoculated groups, 2 T viride-inoculated groups, and 2 control (tent or pen) groups. One of each pair of sporetreated groups and the tent control group were exposed 7 times to sterilized fine feedyard dust (mean c SD particle diameter, < 7.72 c 0.69 km) for 4 hours in a specially constructed tent. Goats in the 4 fungal treatment groups were inoculated intratracheally 5 times with a fungal spore preparation (30 mL), whereas tent control goats were intratracheally inoculated with physiologic saline (0.9% NaCl) solution (30 mL). Pen control goats were not inoculated or exposed to dust. Goats received an IV challenge with equine RBCs to assess antibody responses to foreign antigens. Postmortem examinations were performed at study completion (day 68) to evaluate lung tissue lesions. Results--5 of 7 deaths occurred between days 18 and 45 and were attributed to fine dust exposures prior to fungal treatments. Fine dust inhalation induced similar lung lesions and precipitating antibodies among spore-treated goats. Following spore inoculations, dust-exposed goats had significantly more spores per gram of consolidated lung tissue than did their nonexposed counterparts. Conclusions and Clinical Relevance--Fine dust inhalation appeared to decrease the ability of goats to successfully clear fungal spores from the lungs following intratracheal inoculation.

AN - 70502451; 18361687 AB - Listeria monocytogenes has been implicated in several listeriosis outbreaks linked to the consumption of presliced ready-to-eat (RTE) deli meats. The possible contamination of sliced RTE meats by L. monocytogenes during the slicing process has become a public health concern. The objectives of this study were to investigate the transfer phenomena of L. monocytogenes between a meat slicer and ham slices, and to develop empirical models to describe the transfer during slicing. A six-strain cocktail of L. monocytogenes was inoculated onto a slicer blade to an initial level of approximately 3, 6, or 9 log(10) colony-forming units (CFU)/blade (2, 5, or 8 log CFU/cm(2) of the blade edge area), and then the ham was sliced to a thickness of 1 to 2 mm (Case I). As a second cross-contamination scenario (Case II), a clean blade was used to slice ham previously inoculated with L. monocytogenes (3, 6, or 9 log(10) CFU per meat surface of ca. 100 cm(2)) prior to slicing uninoculated ham. The ham slicing rate was maintained at an average of three to four slices per minute for both Case I and II. Although the overall recovery ratio, including slicer surfaces and collected ham slices, was less than 100%, more ham slices were contaminated with L. monocytogenes when the blade was contaminated with higher initial levels of L. monocytogenes. Empirical models were developed to describe the transfer of L. monocytogenes between blade and ham slices. The models may be applied to predict the number of ham slices that may be contaminated by a L. monocytogenes-contaminated slicer during ham slicing operation. However, the models are both microbial load and contamination route dependent, which might limit their applications to certain conditions. This study showed the initial step for the development of surface transfer model and discussed the factors that might need to be considered and included in future study to expand the model applications.

AN - 70485208; 18208516 AB - Serine palmitoyltransferase (SPT) catalyzes the first step in sphingolipid biosynthesis, and downregulation of this enzyme provides a means for exploring sphingolipid function in cells. We have previously demonstrated that Arabidopsis SPT requires LCB1 and LCB2 subunits for activity, as is the case in other eukaryotes. In this study, we show that Arabidopsis has two genes (AtLCB2a and AtLCB2b) that encode functional isoforms of the LCB2 subunit. No alterations in sphingolipid content or growth were observed in T-DNA mutants for either gene, but homozygous double mutants were not recoverable, suggesting that these genes are functionally redundant. Reciprocal crosses conducted with Atlcb2a and Atlcb2b mutants indicated that lethality is associated primarily with the inability to transmit the lcb2 null genotype through the haploid pollen. Consistent with this, approximately 50% of the pollen obtained from plants homozygous for a mutation in one gene and heterozygous for a mutation in the second gene arrested during transition from uni-nucleate microspore to bicellular pollen. Ultrastructural analyses revealed that these pollen grains contained aberrant endomembranes and lacked an intine layer. To examine sphingolipid function in sporophytic cells, Arabidopsis lines were generated that allowed inducible RNAi silencing of AtLCB2b in an Atlcb2a mutant background. Studies conducted with these lines demonstrated that sphingolipids are essential throughout plant development, and that lethality resulting from LCB2 silencing in seedlings could be partially rescued by supplying exogenous long-chain bases. Overall, these studies provide insights into the genetic and biochemical properties of SPT and sphingolipid function in Arabidopsis.

AN - 70474302; 18387121 AB - Cantaloupes are associated with recent outbreaks of foodborne illnesses and recalls. Therefore, new approaches are needed for sanitization of whole and cut fruit. In the present study, whole cantaloupes were submerged into water in the following 3 conditions: 10 degrees C water for 20 min (control), 20 ppm chlorine at 10 degrees C for 20 min, and 76 degrees C water for 3 min. Populations of microflora were measured on the rinds of the whole cantaloupes. Quality and microbial populations of fresh-cut cantaloupes prepared from whole fruit were analyzed after 1, 6, 8, 10, 13, 16, and 20 d of storage at 4 degrees C. The hot water significantly reduced both total plate count (TPC) and yeast and mold count on rind of whole fruits while chlorine or cold water wash did not result in a significant reduction of microbial population. Fresh-cut pieces prepared from hot water-treated cantaloupes had lower TPC than the other 2 treatments in the later storage periods (days 13 to 20) in 2 of 3 trials. The hot water treatment of whole fruits was inconsistent in reducing yeast and mold count of fresh-cut pieces. Soluble solids content, ascorbic acid content, fluid loss, and aroma and appearance scores were not consistently affected by either hot water or chlorine treatment. Our results suggested that hot water pasteurization of whole cantaloupes frequently resulted in lower TPCs of fresh-cut fruit during storage and did not negatively affect quality of fresh-cut cantaloupes.

RpoS also positively regulates 2 of the 3 acid-resistance systems of E. coli under aerobic growth conditions and enables the pathogen to survive gastric acid challenge. We selected 7 enterohemorrhagic E. coli isolates, 6 of which are known to carry defective rpoS gene, and then analyzed resistance to synthetic gastric juice after the strains were inoculated on fresh-cut lettuce and stored under modified atmosphere packaging (MAP) conditions. Subatmospheric oxygen partial pressures in MAP enabled all 6 rpoS-defective isolates to induce acid resistance over the 8-d storage period if the temperature was >or= 15 degrees C. No acid resistance was induced for MAP-stored lettuce left at temperatures 0.285; P<0.001). In addition, we identified a trichothecene chemotype cline in Canada and documented a recent and significant shift in FHB pathogen composition by demonstrating that the 3ADON chemotype frequency in western Canada increased more than 14-fold between 1998 and 2004. On average, isolates from 3ADON populations produced significantly (P<0.05) more trichothecene and had significantly (P<0.005) higher fecundity and growth rates than isolates from the 15ADON population. These results indicate that selection is driving the rapid spread of an introduced pathogen population that is more toxigenic and potentially more vigorous. The discovery of this previously unrecognized pathogen diversity has significant implications for food safety and cereal production in North America.

AN - 69367597; 18668977 AB - Compartmentalisation is a new tool for disease management within a country. In aquaculture, the successful application of compartmentalisation is largely dependent on the system of production and the epidemiology of the disease(s) for which the compartment is being defined. Therefore, compartmentalisation may not be universally applicable across all systems and diseases. The paper examines the implementation of the concept, providing examples of specific industries, and discusses the application of hazard analysis and critical control points (HACCP) to the biosecurity of the system. The role of compartmentalisation in the management of aquaculture disease emergencies is also discussed.

AN - 69194657; 18468037 AB - The objective in this study was to assess breed effects in fecal prevalence of Escherichia coli O157:H7 in heifers on a development program in Florida and in their steer half siblings in stocker and feedlot phases in Oklahoma. A secondary objective was to characterize fecal shedding of Campylobacter and Salmonella in subsets of the same samples. After weaning, heifers (n = 501; purebreds and F1 crosses of Angus, Brahman, and Romosinuano) were preconditioned and placed in a local development program. Steers (n = 481) were transported to Oklahoma, where they grazed wheat for 6 months and then were placed in feedlot pens. Fecal samples were obtained at least every 28 days for 12 months on most animals. None of the 10,982 samples tested positive for E. coli O157:H7. Overall fecal prevalences of Campylobacter and Salmonella in heifers were 1.7 and 0.04%, respectively. Corresponding overall prevalences in steer samples were 27.2 and 0.6%. Campylobacter isolates were mostly C. jejuni and were tetracycline resistant. Eight Salmonella isolates were Salmonella Typhimurium that were either quad or penta resistant, most often to ampicillin, chloramphenicol, sulfamexathole, and tetracycline. Feedlot steers had greater odds of positive detection of Campylobacter (odds ratio, 8.5; confidence interval, 3.7, 19.5) than when grazing winter wheat. No breed effect was detected for fecal prevalence of these pathogens.

AN - 69192675; 18459387 AB - Callicarpenal and intermedeol are two insect-repellent terpenoids isolated from leaves of American beautyberry (Callicarpa americana L.; Verbenaceae) and Japanese beautyberry (Callicarpa japonica Thunb.). The repellency of these two terpenoids against workers of red imported fire ants, Solenopsis invicta Buren, black imported fire ants, Solenopsis richteri Forel, and a hybrid of these two species was evaluated using digging bioassays. In a multiple choice digging bioassay using two colonies from each species and their hybrid, callicarpenal showed significant repellency at concentration as low as 50 ppm against both red imported fire ant colonies and 6.25 ppm against all black imported fire ant and hybrid colonies. Intermedeol showed significant repellency at concentration as low as 1.50 ppm against both red imported fire ant colonies and 6.25 ppm against all black imported fire ant and hybrid colonies. In total, 15 colonies, five colonies from each species and the hybrid, were tested on callicarpenal and intermedeol at 50 ppm in a two-choice digging bioassay. Both callicarpenal and intermedeol showed repellency against all colonies, and intermedeol showed significantly greater repellency than callicarpenal against both species and their hybrid.

AN - 69192153; 18459433 AB - Insect infestations in stored grain cause extensive damage worldwide. Storage insect pests, including the Indianmeal moth, Plodia interpunctella (Hübner) (Lepidoptera: Pyralidae); Sitophilus spp. (Coleoptera: Curculionidae); and their natural enemies [e.g., Cephalonomia tarsalis (Ashmead) (Hymenoptera: Bethylidae), and Anisopteromalus calandrae (Howard) (Hymenoptera: Pteromalidae)] inhabit a temporary, but stable ecosystem with constant environmental conditions. The objective of the present experiment was to assess the efficacy of using ethylene glycol antifreeze in combination with nutrient solutions to monitor storage insect pest and natural enemy populations in three bins of corn, Zea mays L. The treatments were deionized water, a diluted (1:5 antifreeze:water) antifreeze solution, 10% honey, 10% honey in the diluted antifreeze solution, 10% beer in the diluted antifreeze solution, 10% sucrose in the diluted antifreeze solution, and a commercial pheromone trap suspended in a 3.8-liter container filled with 300-ml of diluted antifreeze solution. The seven treatments captured storage insect pests and their natural enemies in the bins at 33-36 degrees C and 51-55% RH. The pheromone trap in the container with the diluted antifreeze captured significantly more P. interpunctella than the other treatments, but a lower percentage (7.6%) of these captures were females compared with the rest of the treatments (> 40% females). All trapping solutions also captured Sitophilus spp. and other beetle species, but the captures of the coleopteran pests were not significantly different among the seven treatments (P > 0.05). Two parasitoid wasps also were captured in the study. The number of A. calandrae was different among the seven treatments (P 0.05). Most A. calandrae adults were captured by the 10% honey in the diluted antifreeze, whereas the fewest were captured in the deionized water. Microbial growth was observed in the 10% honey solution, but no microbial growth occurred in the rest of the treatments, including 10% honey in the diluted antifreeze solution. The results of insect captures and microbial growth demonstrated that antifreeze could be used as a part of storage insect monitoring and/or control programs.

AN - 69191776; 18459390 AB - Codling moth, Cydia pomonella (L.), is the major pest of apple (Malus spp.) in the western United States and many other regions of the world. The codling moth granulovirus (CpGV) provides a selective and safe means of its control. We assessed the long-term stability and storage potential of two commercial formulations of CpGV, Cyd-X, and Virosoft. All assays were performed with individual C. pomonella neonate larvae in 2-ml vials on 1 ml of artificial larval diet that was surface inoculated with 10 microl of the test virus suspension. Baseline quantitative assays for the two formulations revealed that the LC50 and LC95 values (occlusion bodies per vial) did not differ significantly between the formulations. For year-long studies on Cyd-X stability, the product was stored at -20, 2, 25, and 35 degrees C, and quantitative bioassays were conducted after 0, 3, 6, and 12 mo of storage. Cyd-X retained good larvicidal activity from -20 to 25 degrees C, and it was the least negatively affected at the lowest temperature. Storage of Cyd-X at 35 degrees C was detrimental to its larvicidal activity within 3 mo of storage. For longer term storage studies, Cyd-X and Virosoft formulations were stored at 2, 25, and 35 degrees C, and assayed for larvicidal activity over a 3-yr period. For recently produced product, a 10-microl sample of a 10(-5) dilution of both formulations resulted in 95-100% mortality in neonate larvae. Larvicidal activity for the Cyd-X formulation remained essentially unaffected for 156 wk when stored at 2 and 25 degrees C, but it began to decline significantly after 20 wk of storage at 35 degrees C. The Virosoft formulation stored at 2 degrees C also remained active throughout the 3-yr study, but it began to decline in larvicidal activity after 144 wk at 25 degrees C and 40 wk at 35 degrees C. The information reported in this study should be useful to growers and commercial suppliers for avoiding decreases in CpGV potency due to improper storage conditions.

AN - 69191351; 18459404 AB - Boll weevil traps baited with a ComboLure (25 of mg grandlure + 30 mg of eugenol + 90 of mg dichlorvos [DDVP]), an extended-release lure (25 mg of grandlure + 30 mg of eugenol + 60 of mg DDVP kill-strip), and extended-release lure with no DDVP were evaluated for boll weevil, Anthonomus grandis grandis Boheman (Coleoptera: Curculionidae), captures in South Texas cotton, Gossypium hirsutum L., fields during February-March 2005 and March-April 2006. The traps were serviced once a week for five consecutive weeks by using the same methodology as active boll weevil eradication programs. Mean captured boll weevils from extended-release lures with no DDVP were significantly higher in five of 10 trapping weeks compared with captures of the ComboLure and extended lure. Weekly mortality of boll weevils captured was similar for the ComboLure (72.6 +/- 4.7%) and extended lure + DDVP (73.5 +/- 4.0%), and both were significantly higher than the extended lure (32.8 +/- 5.0%) with no DDVP. The presence or absence of DDVP did not significantly affect the sex ratio of field-captured boll weevils. We found no functional reasoning for using DDVP in large scale trapping of boll weevils regardless of the formulation or presentation in the trap. We conducted two additional trapping evaluations after the 2005 and 2006 studies, but the numbers of boll weevils captured were too low for statistical comparisons, indicating that boll weevil eradication is reducing populations in the Rio Grande Valley of Texas.

AN - 68095407; 18356960 AB - Mutability of the w4 flower color locus in soybean, Glycine max (L.) Merr., is conditioned by an allele designated w4-m. Germinal revertants recovered among self-pollinated progeny of mutable plants have been associated with the generation of necrotic root mutations, chlorophyll-deficiency mutations, and sterility mutations. A total of 24 necrotic root mutant lines were generated from a total of 24 independent reversion events at the w4-m locus. The initial mutable population included 4 mutable categories for w4-m, designated (1) low frequency of early excisions, (2) low frequency of late excisions, (3) high frequency of early excisions, and (4) high frequency of late excisions. These mutable categories were based upon flower phenotype, i.e., somatic tissue. A total of 22 of 24 necrotic root mutations occurred from germinal reversions classified in the high frequency of excision categories. Of these 22 mutants, 14 came from early excisions and 8 came from late excisions. These necrotic root mutants were allelic to 6 previously identified necrotic root mutants derived from the study of germinal revertants, i.e., gene tagging studies, chemical mutagenesis, and "spontaneous" occurrences from genetic crosses. Thus, all 30 necrotic root mutants in soybean are allelic. An F2 mapping population from the cross of Minsoy (Rn1 Rn1) x T328 (rn1 rn1) was used to map the Rn1 locus using simple sequence repeat (SSR) markers. The Rn1 locus was located between Satt288 and Satt612 on molecular linkage group G.

We present here the first evidence that this enteric pathogen can multiply on the leaves of romaine lettuce plants. The increases in population size of E. coli O157:H7 in the phyllosphere of young lettuce plants ranged from 16- to 100-fold under conditions of warm temperature and the presence of free water on the leaves and varied significantly with leaf age. The population size was consistently ca. 10-fold higher on the young (inner) leaves than on the middle leaves. The growth rates of Salmonella enterica and of the natural bacterial microflora were similarly leaf age dependent. Both enteric pathogens also achieved higher population sizes on young leaves than on middle leaves harvested from mature lettuce heads, suggesting that leaf age affects preharvest as well as postharvest colonization. Elemental analysis of the exudates collected from the surfaces of leaves of different ages revealed that young-leaf exudates were 2.9 and 1.5 times richer in total nitrogen and carbon, respectively, than middle-leaf exudates. This trend mirrored the nitrogen and carbon content of the leaf tissue. Application of ammonium nitrate, but not glucose, to middle leaves enhanced the growth of E. coli O157:H7 significantly, suggesting that low nitrogen limits its growth on these leaves. Our results indicate that leaf age and nitrogen content contribute to shaping the bacterial communities of preharvest and postharvest lettuce and that young lettuce leaves may be associated with a greater risk of contamination with E. coli O157:H7.

In this study, that genetic map was aligned with the third assembly of the genomic sequence of G. zeae strain PH-1 (lineage 7) using seven structural genes and 108 sequenced amplified fragment length polymorphism markers. Several linkage groups were combined based on the alignments, the nine original linkage groups were reduced to six groups, and the total size of the genetic map was reduced from 1,286 to 1,140 centimorgans. Nine supercontigs, comprising 99.2% of the genomic sequence assembly, were anchored to the genetic map. Eight markers (four markers from each parent) were not found in the genome assembly, and four of these markers were closely linked, suggesting that >150 kb of DNA sequence is missing from the PH-1 genome assembly. The alignments of the linkage groups and supercontigs yielded four independent sets, which is consistent with the four chromosomes reported for this fungus. Two proposed heterozygous inversions were confirmed by the alignments; otherwise, the colinearity of the genetic and physical maps was high. Two of four regions with segregation distortion were explained by the two selectable markers employed in making the cross. The average recombination rates for each chromosome were similar to those previously reported for G. zeae. Despite an inferred history of genetic isolation of lineage 6 and lineage 7, the chromosomes of these lineages remain homologous and are capable of recombination along their entire lengths, even within the inversions. This genetic map can now be used in conjunction with the physical sequence to study phenotypes (e.g., fertility and fitness) and genetic features (e.g., centromeres and recombination frequency) that do not have a known molecular signature in the genome.

Recent efforts in analysis of trace and major elements (geochemistry) have provided necessary data to soil survey users in a variety of areas. The first part of this paper provides a brief overview of elemental sources, forms, mobility, and bioavailability; critical aspects important to users of soil survey geochemical data for appropriate use and interpretations. Examples are provided based on data gathered as part of the US soil survey program. The second part addresses the organization of sample collection in soil survey and how soil surveys are ideally suited as a sampling strategy for soil geochemical studies. Geochemistry is functional in characterization of soil types, determining soil processes, ecological evaluation, or issues related to soil quality and health, such as evaluating suitability of soils for urban or agricultural land use. Applications of geochemistry are on-going across the US and are documented herein. This analytical direction of soil survey complements historic efforts of the National Cooperative Soil Survey Program and addresses the increasing need of soil survey users for data that assists in understanding the influence of human activities on soil properties.

Previous agricultural research has shown that crop rotation and the use of cover crops can lead to increases in yield relative to monoculture; however, few studies have been performed within the broader context of diversity-ecosystem function theory and in the absence of chemical inputs. We performed a field experiment in SW Michigan, USA, in which we manipulated the number of crop species grown in rotation and as winter cover crops over a 3-year period to test if varying the number of species in a rotation affected grain yield, a critical metric of ecosystem function in row-crops. The experimental design was unique in that no fertilizer or pesticides were used, and the only management variable manipulated was number of species in the rotation, thus providing a strong comparison to grassland diversity-ecosystem function experiments. Treatments included continuous monocultures of three row-crops, corn Zea mays L., soybean Glycine max (L.) Merr., and winter wheat Triticum aestivum L., and 2- and 3-year annual rotations with and without cover crops (zero, one, or two legume/small grain species), encompassing a range of crop diversity from one to six species. Crop yields and weed biomass were measured annually for 3 years and plant available soil nitrogen was measured over the course of the growing season in the final year of the study. In all 3 years, corn grain yield increased linearly in response to the number of crops in the rotation. Corn yields in the highest diversity treatment (three crops, plus three cover crops) were over 100% higher than in continuous monoculture and were not significantly different from the county average for each of the 3 years despite the absence of chemical inputs. Corn yields in the diversity treatments were strongly correlated with the availability of inorganic soil nitrogen, which was likely influenced by the number of different legume species (crops and cover crops) present in the rotation. In soybean and winter wheat, yield differences among crop diversity treatments were also significant, but of lower magnitude (32 and 53%, respectively), and showed little direct relationship to the number of crop species grown in a rotation. Results demonstrate that agricultural research motivated by ecological theory can provide important insights into the functioning of agroecosystems and enhance our understating of the linkages between diversity and ecosystem function. Importantly, these results suggest that reduced chemical inputs do not necessarily result in yield penalties and provide support for incorporation of crop or species diversity when determining how ecosystem services can be included in food, fiber, and biofuel production.

Although both species contained low amounts of genetic variation, unique alleles were identified in both taxa. Analysis of 22 populations, including pure populations of each species, identified eight populations as containing putative hybrid individuals. Four of these putative hybrid populations were considered pure O. wolfii based on morphological analysis. This study confirms that the native O. wolfii may be at risk not only from habitat destruction, but potentially from genetic swamping where it co-occurs with O. glazioviana. These results can be used as baseline information for future genetic monitoring efforts.

Efficient pathogen detection is critical for ALSD epidemiological studies, particularly when a large sample size is involved. We here report a PCR procedure to detect X. fastidiosa directly from infected almond tissue without the laborious DNA extraction. Plant samples were prepared by freeze-drying and pulverized. Appropriate dilutions of the pulverized freeze-dried tissue (PFT) were determined to minimize the effect of enzyme inhibitors from plant tissue and retain PCR detection of X. fastdiosa cells at a single digit number level. This PFT-PCR procedure was evaluated by comparing to the in vitro cultivation method using 102 symptomatic samples and resulted in a predictive value of 90.8%. PFT-PCR was further applied to monitor the seasonal occurrence of X. fastidiosa from four selected almond trees in two orchards in 2005. The results matched with those of the cultivation method at 92.3%. Considering the simplicity and reliability, we conclude that PFT-PCR is a valuable option for high throughput rapid detection of X. fastidiosa.

Some pollutants, particularly nitrate (NO super(-) sub(3)), are predominantly transmitted through ground water. Riparian buffer zones have the potential to remove contaminants from ground water and reduce the amount of NO super(-) sub(3) that enters surface water. This is a justification for setting aside vegetated buffer strips along waterways. Many riparian zone hydrologic models assume uniform ground-water flow through organic-rich soil under reducing conditions, leading to effective removal of ground-water NO super(-) sub(3) prior to discharge into a stream. However, in a small first-order stream in the mid-Atlantic coastal plain, base-flow generation was highly variable (spatially and temporally). Average base-flow NO super(-) sub(3) loads were greater in winter than summer, and higher during a wetter year than in dryer years. Specific sections of the stream consistently received greater amounts of high NO super(-) sub(3) ground water than others. Areas within the riparian zone responsible for most of the NO super(-) sub(3) exported from the watershed are termed "critical areas." Over this 5-year study, most of the NO super(-) sub(3) exported during base flow originated from a critical area comprising less than 10% of the total riparian zone land area. Allocation of resources to address and improve mitigation function in critical areas should be a priority for continued riparian zone research.

Here, we show that Nod2 agonist muramyldipeptide (MDP) induces Akt phosphorylation in time and dose-dependent manner. The pharmacological inhibitor of phosphatidylinositol 3-kinase (PI3K) (wortmannin) and dominant-negative forms of p85 (the regulatory subunit of PI3K) or Akt enhance, while constitutive active forms of p110 (the catalytic subunit of PI3K) or Akt inhibit, NF-[kappa]B activation and the target gene interleukin (IL)-8 induced by MDP. In addition, the pharmacological inhibitors of PI3K (wortmannin and LY294002) enhance phosphorylation of NF- [kappa]B p65 on Ser529 and Ser536 residues, which result in enhanced p65 transactivation activity. Furthermore, we show that the inhibition of PI3K by the pharmacological inhibitors prevent the inactivation of glycogen synthase kinase (GSK)-3 beta , suggesting that the negative regulation of PI3K/Akt on MDP- induced NF-[kappa]B activation is at least in part mediated through inactivation of GSK-3 beta . Taken together, our results demonstrate that PI3K/Akt pathway is activated by Nod2 agonist MDP and negatively regulates NF-[kappa]B pathway downstream of Nod2 activation. Our results suggest that PI3K/Akt pathway may involve in the resolution of inflammatory responses induced by Nod2 activation.

However, dynamic and complex interactions occur among C. ribicola, five-needled white pines, and the environment. To examine potential evolutionary influences on genetic structure and diversity of C. ribicola in western United States, population genetic analyses of C. ribicola were conducted using amplified fragment length polymorphism (AFLP) molecular markers. The fungus was sampled at six sites. Collections for two of the six sites were from separate plantings of resistant-selected western white pine and sugar pine. Heterozygosity based on polymorphic loci among populations ranged from 0.28 to 0.40, with resistant-selected plantations at the extremes. Genetic differentiation was also highest between these two populations. Principal coordinates analysis and Bayesian assignment placed most isolates that are putative carriers of virulence to major-gene resistance into a discernable cluster, while other isolates showed no clustering by site or host species. These results indicate that C. ribicola in western North America is not genetically uniform, despite its presumed single site of introduction and relatively brief residence. Moreover, major-gene resistance appears to have imposed strong selection on the rust, resulting in reduced genetic diversity. In contrast, no evidence of selection was observed in C. ribicola from hosts that exhibit only multigenic resistance.

Literature on somatic embryogenesis of cotton suggests a number of media modifications that might also prove useful for ovule rescue of interspecific crosses. Additionally, endogenous microbes are common in field grown cotton and these potential contaminants must be controlled if interspecific progeny are to be obtained via large-scale field crossing followed by ovule or embryo culture. This study compared nine tissue culture media and two antimicrobial overlay treatments in a factorial design. The overlay treatments were: a 2 ml overlay of 250 mg l super(-1) cefotaxime, 50 mg l super(-1) tetracycline HCl, 2.5 mg l super(-1) amphotericin B, and 50 mg l super(-1) benomyl applied when the ovules were plated, and no overlay. All of the media in the factorial also contained 250 mg l super(-1) cefotaxime. Crosses were made in a field at Stoneville, MS between the upland cultivar DeltaPine 90 and the G. arboreum accession A sub(2)-190. Antimicrobial compounds greatly improved the efficiency of obtaining interspecific cotton progenies from field-grown fruit. Germination was not affected by the overlay nor did overlay treatment interact with media. Media significantly affected germination. Of the media studied, the highest frequency of germination was observed for MSB with 1.9 g l super(-1) additional KNO sub(3). The addition of 0.5 g l super(-1) asparagine and 1 g l super(-1) glutamine did not affect the number of seedlings obtained. A filter paper growing surface or the addition of 0.5 mg l super(-1) NAA and 0.05 mg l super(-1) kinetin were disadvantageous.

Some southwestern soils were naturally saline due to soil weathering processes and limited rainfall even before irrigation was introduced. Early studies showed that plants take up only a small amount of the salts in water, leaving the bulk of the salts to accumulate in the remaining soil water. Therefore leaching these accumulated salts--applying extra water to move them out of the root zone--is necessary for salinity control and maintaining agricultural productivity.

Having cellular receptors in common with birds and humans, swine provide opportunities for mixed infections and potential for genetic reassortment between avian, human, and porcine influenza. Feral swine populations are rapidly expanding in both numbers and range and are increasingly coming into contact with waterfowl, humans, and agricultural operations. In this study, over 875 feral swine were sampled from six states across the United States for serologic evidence of exposure to influenza. In Oklahoma, Florida, and Missouri, USA, no seropositive feral swine were detected. Seropositive swine were detected in California, Mississippi, and Texas, USA. Antibody prevalences in these states were 1% in Mississippi, 5% in California, and 14.4% in Texas. All seropositive swine were exposed to H3N2 subtype, the predominant subtype currently circulating in domestic swine. The only exceptions were in San Saba County, Texas, where of the 15 seropositive samples, four were positive for H1N1 and seven for both H1N1 and H3N2. In Texas, there was large geographical and temporal variation in antibody prevalence and no obvious connection to domestic swine operations. No evidence of exposure to avian influenza in feral swine was uncovered. From these results it is apparent that influenza in feral swine poses a risk primarily to swine production operations. However, because feral swine share habitat with waterfowl, prey on and scavenge dead and dying birds, are highly mobile, and are increasingly coming into contact with humans, the potential for these animals to become infected with avian or human influenza in addition to swine influenza is a distinct possibility.

Moench) is a flowering perennial plant native to North America and is widely grown as an ornamental flower. It is also grown commercially to make herbal teas and extracts purported to help strengthen the immune system. Propagation is by seed or root cuttings. Aster yellows phytoplasmas (strains belonging to group 16SrI) have been reported to be associated with purple coneflower exhibiting virescence and phyllody symptoms in the northern United States and Canada. A subgroup 16SrI-A phytoplasma was identified to be associated with symptomatic purple coneflower in Wisconsin (2). During the summers of 1994 and 2007, purple coneflower plants in Maryland sporadically exhibited symptoms resembling those caused by phytoplasma infection. Symptoms included stunting, virescence, phyllody, and abnormal flower bud proliferation from the cone. Samples from four symptomatic and two asymptomatic purple coneflower plants were collected. Total nucleic acid was extracted from leaf tissue. To assess the etiology of the disease, nested PCR with universal phytoplasma primer pair P1/P7 followed by R16F2n/R16R2 was employed for the detection of phytoplasmas (1). An amplicon of approximately 1.2 kb was amplified from all four symptomatic purple coneflower plants but not from the two asymptomatic plants. Restriction fragment length polymorphism (RFLP) patterns of 16S rDNA digested singly with restriction enzymes AM, KpnI, HpaI, MseI, HhaI, and RsaI indicated that affected purple coneflower plants were infected by a phytoplasma belonging to aster yellows group 16SrI ('Candidates Phytoplasma asteris'-related strains), subgroup 16SrI-B (1). Nucleotide sequence analysis of cloned 16S rDNA (GenBank Accession Nos. EU333394 and EU333395) confirmed the results from RFLP analyses. To our knowledge, this is the first report of a 16SrI-B phytoplasma infecting an Echinacea sp. in Maryland.

Previous laboratory studies demonstrated that certain water-soluble polyacrylamide solution (WSPAM) and cross-linked PAM granule (XPAM) treatments effectively reduced infiltration into soils. We evaluated the efficacy of these treatments for reducing water seepage losses in an unlined irrigation reservoir. Five treatments were applied to plots on the lower side slopes of a reservoir basin before it was filled in April 2001: controls; 0.016 kg m super(2) WSPAM (1000 mgL super(-1) solution); 0.2 kg m super(-2)XPAM + 0.13 kg m super(-2) NaCl; 0.4 kg m super(-2)XPAM + 0.13 kg m super(-2)NaCl; and 0.8 kg m super(-2)XPAM only. Ring-cylinder seepage meters installed in each experimental plot were used to monitored seepage rates from May through October in 2001 and 2002, without further treatment applications. The WSPAM and XPAM treatments were equally effective for reducing pond seepage in 2002 but not 2001. On average, they reduced mean seepage rates an average 50% relative to the 22.4 mm h super(-1) control value and prevented the loss of 19.7 m of water through the seepage rings over the two irrigation seasons. The 0.016 kg m super(-2) WSPAM and 0.2 kg m super(-2)XPAM + 0.13 kg m super(-2) NaCl treatments are most cost effective, but the greater XPAM rates appeared to be the most durable treatments, since they retained their efficacy through the end of the second irrigation season. Results are consistent with a previous study suggesting that adding NaCl to XPAM treatments reduced required XPAM inputs without reducing treatment efficacy. The WSPAM and XPAM treatments provide several effective options for reducing seepage losses in earthen reservoirs.

However, overall project results could only be continually evaluated at two release and two control sites because the remainder were eventually destroyed or corrupted by floods, droughts, or herbicides. Mean fresh weight biomass of S. molesta ranged from 15.5kgFWm super(-) super(2) during the summer to as low as 2.1kgFWm super(-) super(2) during the winter prior to the release of C. salviniae. Insect populations established within a year of release and initially spread slowly. Damage to S. molesta increased with increasing C. salviniae detections while S. molesta biomass and surface coverage declined at both release sites by more than 99% while remaining unchanged at the control sites. Water in release sites registered higher levels of dissolved oxygen, higher temperatures, and higher pH than water in control sites. This study provides another example of the effectiveness of C. salviniae against S. molesta even in more temperate climates.

However, technical methodologies available to accomplish this measurement are almost entirely unavailable and untested. Experiments were conducted to quantify water movement through soil and peanut plants using deuterium-labeled water applied to simulate a typical irrigation or rainfall event. Soil at four depths and stem tissue samples were collected after the deuterium was applied. The first experiment in Greenville soil was conducted over a 24 h period in order to determine how much water was utilized in a fully charged soil profile. The second experiment in Tifton soil was conducted over a four-day period starting with a relatively dry soil profile in order to determine how long a peanut plant could utilize applied water. Differences in soil water infiltration between overhead irrigation and subsurface drip irrigation were observed, but there was no effect on subsequent peanut water uptake patterns between the two peanut cultivars, Georgia Green and Andru II. The duration of water uptake after a simulated irrigation or precipitation event appears to be between 48 and 72 h for peanut plants. The study demonstrated the utility of applying deuterium-labeled water in order to follow soil infiltration and plant water uptake patterns in a peanut agricultural system.

Identifying effective alternatives to polyacrylamide (PAM) is desired for continued, affordable irrigation erosion control. We compared the effectiveness of a new polysaccharide/PAM amendment with water-soluble, high molecular weight, anionic PAM in two furrow-irrigated field tests in southern Idaho. Test 1 evaluated three rates of the polysaccharide/PAM amendment (6, 12, and 18 mgL super(-1) of polysaccharide/PAM), two rates of PAM (2 and 10 mgL super(-1) of PAM), 10 mg L super(-1) polysaccharide, and a control during two irrigations in a fallow field. Treatments were applied as a solution with furrow inflow water during irrigation advance. Test 1 results indicated that polysaccharide/PAM amendment could improve infiltration and reduce sediment loss compared to untreated furrows, but its effectiveness seemed to diminish when amendment application stopped. Polysaccharide alone did not significantly effect infiltration, runoff, or sediment loss compared to the control for either irrigation, whereas the polysaccharide/PAM amendment significantly increased infiltration and reduced sediment loss for one irrigation. Test 2 compared polysaccharide/PAM amendment and PAM, both applied at either 2 mg L super(-1) (active ingredient) continually during irrigation (dissolved treatments) or as a 20 g per furrow of dry material near the furrow inflow point (patch treatments), during four irrigations on a dry bean field. Both amendments significantly increased cumulative infiltration and decreased cumulative runoff and sediment loss compared to untreated furrows. Dissolved polysaccharide/PAM increased cumulative infiltration 19% compared to the control, while dissolved PAM, patch polysaccharide/PAM, and patch PAM treatments increased cumulative infiltration 13%, 11%, and 7%, respectively, compared to the control. Dissolved and patch PAM and dissolved and patch polysaccharide/PAM treatments significantly reduced cumulative sediment loss 98%, 90%, 65%, and 49%, respectively, compared to the untreated furrows. These test results indicate that the polysaccharide/PAM amendment can be used as an alternative, albeit less effective, to PAM for reducing sediment loss from furrow-irrigated fields.

All model predictions have uncertainty associated with them. Model predictive uncertainty, often expressed as the confidence interval around a model prediction value, may serve as important supplementary information for assisting decision making processes. In this article, we describe a new method called Dual Monte Carlo (DMC) to calculate model predictive uncertainty based on input parameter uncertainty. DMC uses two Monte Carlo sampling loops, which enable model users to not only calculate the model predictive uncertainty for selected input parameter sets of particular interest, but also to examine the predictive uncertainty as a function of model inputs across the full range of parameter space. We illustrate the application of DMC to the process-based, rainfall event-driven Rangeland Hydrology and Erosion Model (RHEM). The results demonstrate that DMC effectively generated model predictive uncertainty from input parameter uncertainty and provided information that could be useful for decision making. We found that for the model RHEM, the uncertainty intervals were strongly correlated to specific model input and output parameter values, yielding regression relationships (r super(2) > 0.97) that enable accurate estimation of the uncertainty interval for any point in the input parameter space without the need to run the Monte Carlo simulations each time the model is used. Soil loss predictions and their associated uncertainty intervals for three example storms and three site conditions are used to illustrate how DMC can be a useful tool for directing decision making.

To address these environmental concerns for wastewater utilization, we installed a subsurface drip irrigation system to apply treated swine wastewater effluent for bermudagrass hay production. The overall study objective was to determine the feasibility of using subsurface drip irrigation (SDI) for treated wastewater effluent applications. The specific objectives for the SDI system were to compare bermudagrass hay production using (1) commercial and wastewater effluent for nutrients, (2) two SDI lateral spacings (0.6 and 1.2 m) installed at 0.3 m below the surface, and (3) two irrigation application rates based on calculated evapotranspiration (ET sub(C)) requirements (75% or 100%). The two-year study measured hay yields, hay biomass, soil nutrients, and soil water nutrients. The SDI system was successfully operated for two years applying effluent and commercial fertilizer to supply the nutrient requirements of the bermudagrass hay. Bermudagrass hay production for 2004 and 2005 ranged from 5.65 to 14 Mg ha super(-1). Results from the SDI system indicated no significant differences between the SDI lateral spacings or irrigation application rates. Treatments using wastewater effluent had significantly higher hay yields and significantly higher nutrient biomass removal rates than the commercial fertilizer treatments. Nitrate-N observed in soil water lysimeters increased with depth, indicating the potential for leaching without proper management. Soil nitrogen and carbon were not significantly different for any of the treatments but did vary slightly over the life of the project.

Unfortunately, none of the random number generators we tested satisfactorily produced the target distribution. The result is generated distributions whose mean even diverges from the mean used to generate them, regardless of the length of run. Non-uniform distributions from short sequences of random numbers are a major problem in stochastic climate generation, because truly uniform distributions are required to produce the intended climate parameter distributions. In order to ensure generation of a representative climate with the stochastic weather generator CLIGEN within a 30-year run, we tested the climate output resulting from various random number generators. The resulting distributions of climate parameters showed significant departures from the target distributions in all cases. We traced this failure back to the uniform random number generators themselves. This paper proposes a quality control approach to select only those numbers that conform to the expected distribution being retained for subsequent use. The approach is based on goodness-of-fit analysis applied to the random numbers generated. Normally distributed deviates are further tested with confidence interval tests on their means and standard deviations. The positive effect of the new approach on the climate characteristics generated and the subsequent deterministic process-based hydrology and soil erosion modelling are illustrated for four climatologically diverse sites.

Diseases that occur in the field can affect the magnitude of these losses. This research examines the storage of roots with rhizomania (caused by Beet necrotic yellow vein virus) and the effectiveness of rhizomania-resistant hybrids in reducing postharvest losses. Roots of susceptible hybrids from sites with rhizomania had respiration rates 30 days after harvest (DAH) that ranged from 0.68 to 2.79 mg of CO sub(2) kg super(-1) h super(-1) higher than roots of the resistant hybrids. This difference ranged from 2.60 to 13.88 mg of CO sub(2) kg super(-1) h super(-1) 120 DAH. Roots of resistant hybrids from sites with rhizomania had 18 kg more sucrose per ton than roots from susceptible hybrids 30 DAH, with this difference increasing to 55 kg Mg super(-1) 120 DAH. The invert sugar concentration of susceptible hybrids from sites with rhizomania ranged from 8.38 to 287 g per 100 g of sucrose higher than that for resistant hybrids 120 DAH. In contrast, differences between susceptible and resistant hybrids in respiration rate, sucrose loss, and invert sugar concentration in the absence of rhizomania were relatively small. Storage losses due to rhizomania can be minimized by planting resistant hybrids and processing roots from fields with rhizomania soon after harvest.

The EPA specifies the performance criteria for the FRM samplers. These criteria for the FRM PM sub(10) samplers are defined as a cutpoint and slope of 10 plus or minus 0.5 mu m and 1.5 plus or minus 0.1, respectively. It is commonly assumed that the performance characteristics of the FRM PM sub(10) sampler do not vary and are independent of the PM characteristics. Several sources have observed errors in the concentrations measured by the FRM PM sub(10) samplers and have suggested that shifts in the sampler performance characteristics may lead to the observed concentration measurement errors. Limited work has been conducted on quantifying the shift in the performance characteristics of the FRM PM sub(10) sampler operating under field conditions. Recent work at a south Texas cotton gin showed that true PM sub(10) concentrations were 55% of the concentrations measured by the FRM PM sub(10) sampler. If the FRM PM sub(10) sampler were operating within the performance criteria range specified by the EPA, then the true concentrations would be within approximately 12% of the concentrations measured by the FRM PM sub(10) sampler. The focus of this work was to quantify the shifts in the cutpoint and slope of the penetration curve of the FRM PM sub(10) sampler. Results show that the cutpoint and slope of the FRM PM sub(10) sampler shifted substantially and ranged from 13.8 to 34.5 mu m and from 1.7 to 5.6, respectively, when exposed to large PM as is characteristic of agricultural sources. These shifts in the cutpoint and slope of the FRM PM sub(10) sampler resulted in overestimation of true PM sub(10) concentrations by 145% to 287%.

Previous field studies had identified plants attractive (Lobularia maritima L.) and unattractive (Spermacoce verticillata L) to certain opiine braconids (Hymenoptera). Under laboratory conditions, Diachasmimorpha longicaudata (Ashmead), a parasitoid of tephritid fruit fly larvae and representative opiine, responded in flight tunnels to L. maritima but not to S. verticillata. Volatile chemicals of the two flowers were collected and analyzed by using capillary gas liquid chromatography and mass spectral analysis. Acetophenone was isolated from L. maritima but not from S. verticillata. In flight tunnels, D. longicaudata were exposed to 10 concentrations (doses) of acetophenone. Female parasitoids showed a significant attraction to several acetophenone doses, with concentrations of 25 and 50 ng the most attractive. No odor source, either floral or floral-derived, was attractive to male parasitoids. Reliable trapping systems for parasitoid species, particularly species such as D. longicaudata used for augmentative biological control, would be a valuable monitoring tool. At present, there are few, if any, florally derived synthetic lures for attracting hymenopteran parasitoids.

R. China AN - 20809156; 8132140 AB - Huanglongbing (HLB, yellow shoot disease, ex. citrus greening disease), caused by Candidates Liberibacter spp., is highly destructive to citrus production in Asia, Africa, and South America. Although primarily affecting sweet orange and mandarin, HLB has long been observed in pummelo in Guangdong Province, People's Republic of China; however, the disease in pummelo has received little research attention. Accordingly, it remains unclear how closely related the strains of Ca. Liberibacter in pummelo are to those in other citrus species. In this study, the loci of 16S rDNA, rplAJ ( beta -operon of ribosomal protein), and an outer membrane protein (omp) gene were analyzed and characterized among strains of Ca. Liberibacter in pummelo samples from six different locations in Guangdong. Sequence comparisons indicated that 'Candidatus Liberibacter asiaticus', but not 'Ca. Liberibacter africanus' or 'Ca. Liberibacter americanus', was exclusively associated with HLB symptoms in pummelo. The pummelo strains of 'Ca. Liberibacter asiaticus' from Guangdong were highly homogeneous. Analyses of single-nucleotide polymorphisms in the omp locus showed that the Guangdong pummelo strains grouped with 'Ca. Liberibacter asiaticus' strains from Thailand, Nepal, and an unspecified location in China but differed from the Philippine and China-Behai strains. Based on tide sequence homogeneity at the omp locus, the history of pummelo culture and the means by which HLB is known to be spread, we believe that, likely, the pummelo strain of 'Ca. Liberibacter asiaticus' recently was spread to pummelo in the study areas from infected sweet orange or mandarin trees by insect vectors or by propagation of pummelo infected elsewhere.

To investigate the influence of BNYVV on storability, six sugar beet cultivars varying for resistance to BNYVV were grown in 2005 and 2006 in southern Idaho fields with and without BNYVV-infested soil. At harvest, samples from each cultivar were placed in an outdoor ventilated pile in Twin Falls, ID and were removed at 40-day intervals starting at the end of October. After 144 and 142 days in storage, sugar reduction across cultivars averaged 20 and 13% without and 68 and 21% with BNYVV for the 2005 and 2006 roots, respectively. In the December samplings, frozen root area was 1 and 2% without and 25 and 41% with BNYVV for the 2005 and 2006 roots, respectively. Root rot was always worse with stored roots from BYNVV-infested soil in December, January, and February samplings. Root weight loss was variable in 2005; however, in 2006, an increase in weight reduction always was associated with BNYVV-infested roots. In order to prevent losses in rhizomania-infested areas, cultivars should be selected for storability as well as rhizomania resistance.

We examined how the oviposition behaviour of zoophytophagous Orius insidiosus and the subsequent longevity of its progeny are influenced by the physical structure and internal anatomy of five plant species. Female O. insidiosus oviposit into plant species with the thinnest layers of epidermal and collenchyma cells, a decision that is significantly correlated with the survival of their offspring. Once a plant species is chosen, the female mainly bases her oviposition decisions on epidermal thickness and the surface density of hair-like appendages on the plants. That females laid more eggs and nymphs survived longer on plants with thinner external tissues suggest that the mechanisms that drive female oviposition decisions have evolved such that optimal plant-based resources are available for the females' progeny. Microscopic examination of plant anatomical features revealed that vascular and cellular tissues are fully accessible to the piercing-sucking mouthparts of the developing insects, suggesting that multiple sources of plant nutrients are available to this omnivore. The ecological implications of plant-based contributions to O. insidiosus fitness are discussed.

Typhimurium) in the presence of the mammalian hormone norepinephrine revealed up-regulation of genes in the flagellar and chemotaxis regulon. Motility assays confirmed enhanced motility of wild-type S. Typhimurium in the presence of norepinephrine that could be blocked by the a-adrenergic antagonist, phentolamine. Furthermore, a mutation in the qseC gene, encoding the sensor kinase of the two-component QseBC quorum-sensing system, also diminished motility of S. Typhimurium. To investigate the role of S. Typhimurium QseC in vivo, 13-week old pigs were intranasally inoculated with equal concentrations (1x10 super(9)CFU) of wild-type S. Typhimurium and a qseC mutant. Over a 1-week competitive index experiment, the qseC mutant displayed decreased colonization of the gastrointestinal tract compared to the wild-type parent strain. Thus, this study has identified a role for the QseBC quorum-sensing signal transduction system in motility and swine colonization of S. Typhimurium. Cross-talk between cell-cell communication systems in Salmonella (quorum sensing) and host hormones may explain opportunistic behaviors of the pathogen, such as immune evasion and stress-induced recrudescence of Salmonella, during fluctuations of host hormone levels.

We designed a field experiment to evaluate the differential competitive effects of the invasive annual grass downy brome, the invasive biennial forb dyer's woad, and the reclamation shrub prostrate kochia, on nitrate acquisition of the perennial grass crested wheatgrass, the native forb western yarrow, and the native shrub big sagebrush. Individual plants were grown in two-plant neighborhoods, and a K15NO3 tracer was injected into the soil between plants and recovered from leaf material after 5 to 11 d. We also evaluated neighbor effects on shoot and root growth, leaf carbon:nitrogen ratio, and leaf nitrogen concentrations to better understand how these traits are associated with differences in nitrate acquisition and nitrogen allocation among the three growth forms. Nitrate acquisitions by crested wheatgrass and western yarrow were significantly lower when competing with downy brome than with dyer's woad and prostrate kochia; however, competitors had similar, negative effects on nitrate acquisition by big sagebrush. Nitrate acquisition ratios between competing neighbors revealed that: (1) the grasses always acquired more nitrate than neighbors of a different growth form, (2) western yarrow was equally competitive with dyer's woad and prostrate kochia, and (3) all neighbors acquired more nitrate than big sagebrush. More successful competition for nitrate in the grasses was associated with greater specific root length. Compared to species of the same respective growth form, the two invasive weeds (downy brome and dyer's woad) and prostrate kochia always had significantly lower leaf carbon:nitrogen ratio, and greater leaf nitrogen concentration, which have been broadly correlated with leaf lifespan and nutrient use efficiency, and indicate differing strategies to persist in the semiarid shrub-steppe ecosystems.

PLA films were incorporated with nisin to for control of foodborne pathogens. Antimicrobial activity of PLA-nisin films against Listeria monocytogenes, Escherichia coli O157:H7, and Salmonella Enteritidis were evaluated in culture media and liquid foods (orange juice and liquid egg white). Scanned electron micrograph and confocal laser microscopy revealed that nisin particles were evenly distributed in PLA polymer matrix on the surface and inside of the PLA-nisin films. PLA-nisin significantly inhibited growth of L. monocytogenes in culture medium and liquid egg white. The greatest inhibition occurred at 24 h when the cell counts of L. monocytogenes in the PLA-nisin samples were 4.5 log CFU-mL less than the controls. PLA-nisin reduced the cell population of E. coli O157:H7 in orange juice from 7.5 to 3.5 log at 72 h whereas the control remained at about 6 log CFU-mL. PLA-nisin treatment resulted in a 2 log reduction of S. Enteritidis in liquid egg white at 24 degree C. After 21 d at 4 degree C the S. Enteritidis population from PLA-nisin treated liquid egg white (3.5 log CFU-mL) was significantly less than the control (6.8 log CFU-mL). E. coli O157:H7 in orange juice was more sensitive to PLA-nisin treatments than in culture medium. The results of this research demonstrated the retention of nisin activity when incorporated into the PLA polymer and its antimicrobial effectiveness against foodborne pathogens.

Eight species of phytophagous stink bugs were found in peanuts over the 5-yr study. The predominant stink bug species were Nezara viridula (L), Euschistus senvus (Say), Euschistus quadrator (Rolston), and Oebalus pugnax pugnax (F.). The remaining 4 species, Acrostemum hilare (Say), Euschistus tristigmus (Say), Euschistus ictericus (L), and Thyanta custator accerra McAtee, were found in relatively low numbers. All developmental stages of N. viridula, E. servus, E. quadrator, A. hilare, and O. p. pugnax were collected at various times in the study indicating that these 5 species of stink bugs were developing on this crop. Seasonal abundance of N. viridula and E. servus nymphs and adults provided further support that these 2 species of stink bugs developed on peanuts. At least 1 generation of N. viridula and E. servus occurred in peanuts each year, and generally some of the adults that developed on peanuts oviposited on peanuts producing another generation of nymphs in this crop. Because only adults of T. c. accerra, E. tristigmus, and E. ictericus were found in peanuts, these 3 stink bug species probably were not developing on this crop. Adult stink bugs were parasitized by the tachinid parasitoids Trichopoda pennipes (F.) and Cylindromyia spp. Stink bug eggs were parasitized by the scelionids, Trissolcus basalis (Wollaston), Trissolcus thyantae Ashmead, Trissolcus brochymenae (Ashmead), Telenomus podisi Ashmead, and Gryon obesum Masner, and an unknown encyrtid species. Geocoris punctipes (Say), Geocoris uliginosus (Say), Orius insidiosus (Say), Podisus maculiventris (Say), and Oxyopes salticus Hentz preyed on stink bugs in peanuts. Peanuts harbor populations of stink bugs and their natural enemies, and thus the role peanuts play in landscape ecology of stink bugs needs to be ascertained to better understand how to manage stink bug populations in landscapes in which peanuts are associated with other crops.

In a no-choice experiment, azinphos-methyl sprayed on cherries reduced oviposition by 98.5% compared with the control, whereas spinosad bait, imidacloprid, and thiamethoxam reduced it by 74.4% to 91.8% and indoxacarb reduced it by 61.7%. Despite reducing oviposition to similar levels, imidacloprid did not cause as much mortality as spinosad bait, spinosad, or thiamethoxam. Imidacloprid reduced oviposition more than indoxacarb, even though the two caused similar mortality. In a choice experiment, there were no differences in oviposition in untreated and insecticide-treated cherries, except fewer eggs were laid in spi-nosad-bait treated than untreated cherries. In a no-choice experiment using kaolin, flies laid up to 36 times more eggs in control than treated cherries. In a choice experiment, flies laid 10 times more eggs in untreated than kaolin-treated cherries. Results show oviposition by ft indifferens can be reduced to similar levels by materials with significantly different toxicities, and that none except spinosad bait is an oviposition deterrent. The high levels of oviposition reduction indicate these insecticides (except indoxacarb) can protect fruit from mature flies, but more work is needed to modify or improve them so that they can reduce oviposition as much as azinphos-methyl. In residential trees where none of these insecticides is desirable, kaolin may be useful in reducing oviposition and preventing buildup of R. indifferens populations.

All coarse woody debris was removed from four 9-ha plots of mature loblolly pine (Pinus taeda L.) in 1997 and again in 1998. We sampled arthropods in coarse woody debris removal and control stands using crawl traps that captured arthropods crawling up tree boles, burlap bands wrapped around trees, and cardboard panels placed on the ground. We captured 27 orders and 172 families of arthropods in crawl traps whereas 20 arthropod orders were observed under burlap bands and cardboard panels. The most abundant insects collected from crawl traps were aphids (Homoptera: Aphi-didae) and ants (Hymenoptera: Formicidae). The greatest biomass was in the wood cockroaches (Blattaria: Blattellidae), caterpillars (Lepidoptera) in the Family Noctuidae, and adult weevils (Coleoptera: Curculionidae). The most common group observed underneath cardboard panels was isoptera (termites), and the most common taxon under burlap bands was wood cockroaches. Overall, arthropod abundance and biomass captured in crawl traps was similar in control and removal plots. In contrast, we observed more arthropods under burlap bands (mean plus or minus SE; 3,021.5 plus or minus 348.6, P = 0.03) and cardboard panels (3,537.25 plus or minus 432.4, P = 0.04) in plots with coarse woody debris compared with burlap bands (2325 plus or minus 171.3) and cardboard panels (2439.75 plus or minus 288.9) in plots where coarse woody debris was removed. Regression analyses showed that abundance beneath cardboard panels was positively correlated with abundance beneath burlap bands demonstrating the link between abundance on the ground with that on trees. Our results demonstrate that short-term removal of coarse woody debris from pine forests reduced overall arthropod availability to bark-foraging birds.

There are two strains of plum curculio, the univoltine 'northern' strain and the multivoltine 'southern' strain. Voltinism associated with populations located in the mid-Atlantic region has been unclear from historic records, with recent studies suggesting multivoltine populations. In studies conducted in West Virginia, female plum curculios obtained from emergence and screen traps and from samples of host tree canopies strongly indicate the presence of at least some multivoltine populations, based on an ovarian development bioassay. Two periods of active oogenesis were detected. The first occurred in early spring between late April and early May and represented overwintered females reaching sexual maturity. A second period of oogenesis was detected beginning in late June and continuing through early August. Based on degree day accumulations and known developmental rates of plum curculio, the mid-Atlantic is comprised, at least in part, of multivoltine populations. Fruit growers, therefore, must consider that plum curculio can pose a threat to tree fruit throughout the active growing season.

Twenty-two white-tailed deer were divided into four groups. One group (n = 5) received 10 super(9) colony-forming units (cfu) BCG via a lipid-formulated oral bait; one group (n = 5) received 10 super(9) cfu BCG in culture directly to the oropharynx, one group (n = 6) was vaccinated with 10 super(6) cfu BCG subcutaneously, and one group served as a control and received culture media directly to the oropharynx (n = 6). All animals were challenged 3 mo after vaccination. Five months postchallenge the animals were examined for lesions. Results indicate that both oral forms of BCG and parenterally administerd BCG offered significant protection against M. bovis challenge as compared to controls. This study suggests that oral BCG vaccination may be a feasible means of controlling bovine tuberculosis in wild white-tailed deer populations.

Duke Forest free-air CO sub(2) enrichment (FACE) plots were split and half of each ring fertilized with 112 kg ha super(-1) elemental N applied in two applications in March and April 2005. Measurements of needle length (L), mass per unit area (LMA), N concentration (N sub(1)) on a mass and an area basis, light-saturated net photosynthesis per unit leaf area (A sub(a)) and per unit mass (A sub(m)), and leaf conductance (g sub(L)) began after the second fertilizer application in existing 1-year-old foliage (F sub(O)) and later in developing current-year first-flush (F sub(C1)) and current-year second-flush (F sub(C2)) foliage. Elevated [CO sub(2)] increased A sub(a) by 43 and 52% in F sub(O) and F sub(C1) foliage, respectively, but generally had no significant effect on any other parameter. Fertilization had little or no significant effect on L, LMA, A or g sub(L) in F sub(O) foliage; although N sub(1) was significantly higher in fertilized trees by midsummer. In contrast, fertilization resulted in large increases in L, N sub(1), and A in F sub(C1) and F sub(C2) foliage, increasing A sub(a) by about 20%. These results suggest that, although both needle age classes accumulate N following fertilization, they use it differently--current-year foliage incorporates N into photosynthetic machinery, whereas 1-year-old foliage serves as an N store. There were no significant interaction effects of elevated [CO sub(2)] and fertilization on A. Elevated [CO sub(2)] increased the intercept of the A:N sub(1) relationship but did not significantly affect the slope of the relationship in either foliage age class.

Overall categories of direct plant defenses against insect herbivores include limiting food supply, reducing nutrient value, reducing preference, disrupting physical structures, and inhibiting chemical pathways of the attacking insect. Major known defense chemicals include plant secondary metabolites, protein inhibitors of insect digestive enzymes, proteases, lectins, amino acid deaminases and oxidases. Multiple factors with additive or even synergistic impact are usually involved in defense against a specific insect species, and factors of major importance to one insect species may only be of secondary importance or not effective at all against another insect species. Extensive qualitative and quantitative high throughput analyses of temporal and spatial variations in gene expression, protein level and activity, and metabolite concentration will accelerate not only the understanding of the overall mechanisms of direct defense, but also accelerate the identification of specific targets for enhancement of plant resistance for agriculture.

In these two experimental infection studies, we compared the susceptibilities of bison and elk to FMD virus (FMDV), respectively, with that of cattle; determined whether intra- and interspecies transmission could occur in bison and cattle, and elk and cattle; determined suitability of conventional available laboratory tests to detect FMDV infection in bison and elk; and investigated whether bison or elk are efficient long-term carriers of FMDV. In both studies, after a period of acclimation to the containment at Plum Island Animal Disease Center, animals were infected by intraepithelial tongue inoculation with 10,000 bovine tongue infective doses of FMDV, strain O1 Manisa. Inoculated animals were kept with contact animals; subsequently, inoculated and/or exposed contact animals were placed in rooms with unexposed animals. All bison developed oral mucosal and foot lesions similar to those of cattle. Bison developed fever, lameness, inappetence, and ptyalism. Physical examinations on bison revealed numerous small vesicles and erosions affecting tongue, gingiva, muzzle, hard and soft palates, coronary bands, and interdigital skin. Inoculated elk developed transient fever and mild focal tongue and foot lesions. Contact elk developed neither clinical signs nor gross pathologic lesions of FMD. At necropsy, lesions in bison included numerous extensive vesicles, erosions, and/or ulcers in the oral cavities, feet, and rumen pillars depending on the stage of disease. Less extensive oral, foot, and rumen lesions were present in the inoculated elk. All bison and inoculated elk developed antibodies to FMDV and were positive for FMDV by reverse transcription-polymerase chain reaction (RT-PCR). Transmission occurred between cattle and bison, and bison and bison. It did not occur between elk and cattle. Elk-to-elk transmission studies resulted in only one contact elk developing serologic evidence of a subclinical infection. Other exposed elk developed neither clinical, pathologic, virologic, nor serologic evidence of disease. FMDV was not isolated from animals past 28 days postinfection.

Coli O157:H7 in Cattle AN - 20609039; 8170536 AB - Fecal prevalence of Escherichia coli O157 in ruminants is highest in the summer decreasing to very low levels in the winter. We hypothesize that this seasonal variation is a result of physiological responses within the host animal to changing day-length. To determine the effects of melatonin (MEL) on fecal shedding of E. coli O157:H7 in cattle, eight crossbred beef steers identified as shedding E. coli O157:H7, were allotted to treatment: control or MEL (0.5 mg/kg body weight (BW); 1 x ) administered orally daily for 7 days. After a 5-day period of no treatment, a second MEL dose (5.0 mg/kg BW; 10 x ) was administered daily for 4 days. Fecal samples were collected daily for qualification of E. coli O157:H7. No differences (P > 0.10) were observed in the percentage of E. coli O157:H7 positive fecal samples in steers receiving the 1 x MEL dose, however the 10 x dose decreased (P = 0.05) the percentage of fecal samples E. coli O157:H7 positive. Serum MEL concentrations were higher in the 1 x , but not 10 x , treated animals compared to control animals. Although it is difficult to explain, this may be a result of decreasing day-length increasing serum melatonin concentrations that may have masked any treatment effect on serum melatonin. In a second similar experiment, a second group of cattle (heifers and steers) were administered tryptophan (TRP) over a 17-day experimental period (5 g/head/day for 10 days followed by 10 g/head/day for 7 days). Tryptophan had no effect (P > 0.20) on the percentage of fecal samples positive for E. coli O157. Serum TRP (P 0.20), concentrations were elevated in TRP-treated animals. The decrease in the number of positive fecal samples observed in the first experiment, may be related to gastrointestinal MEL, affected by the 10 x , but not 1 x MEL dose.

A collection of Carolina foxtail obtained from several Arkansas locations over a 4-year period was inoculated with four races of the fungus under greenhouse conditions and, in all cases, inoculation resulted in the formation of irregular, yellow and brown lesions without obvious gray centers that are characteristic for blast on rice. Differences in these lesions were not observed among our collection. These lesions appeared to differ from typical blast lesions on inoculated rice leaves but were evident following artificial inoculation of Carolina foxtail in the greenhouse. M. oryzae races that differed in pathogenicity toward rice cultivars also displayed differences in lesion development on Carolina foxtail. The most virulent race on rice cultivars also produced lesions most rapidly on Carolina foxtail. These lesions developed more quickly on Carolina foxtail than on the most susceptible rice cultivars tested, including a susceptible California cultivar, M202. M. oryzae isolates cultured from these lesions in the infected Carolina foxtail caused typical disease symptoms of blast on inoculated rice cultivars. We suggest that Carolina foxtail is a new and previously unrecognized host for the blast pathogen.

Rings may persist for many years, and current control recommendations are costly and largely ineffective. The goal of this study was to accurately assess the impact of this disease on cranberry, a long-lived, high-value, perennial crop. The rate of fairy ring expansion, rate of formation of new rings, and distribution of rings across three cultivars were determined using a geographical information system (GIS) database that incorporated aerial and satellite imagery. Ring growth rates, estimated from imagery collected over a 10-year period in cv. Ben Lear, averaged 0.455 m in radius per year. Rings were observed in 'Ben Lear' three times more frequently than in either 'Early Black' or 'Stevens' cultivars. Direct sampling showed that estimates for yield within rings were 22 to 68% less than unaffected areas of the field for cv. Ben Lear. These estimates included the effects of fruit rot, which was elevated within rings to 18 to 29% of the total harvest. The impact on yield of 'Stevens' and 'Early Black' was lower than in 'Ben Lear'. Most cranberry cultivars are clonal and variation in fruit morphology within rings, particularly in 'Ben Lear', prompted an analysis of vine genotype. Areas affected by fairy ring in 'Ben Lear' showed an increase in genetic diversity at least 0.4 to 4 times that of unaffected areas. Therefore, it appears that fairy ring not only directly reduces yield but also can increase the host genetic diversity. This likely is due to increased seedling establishment resulting from seed drop when fruit decompose. Because seedlings typically yield less than the parental cultivar, the increase in genetic diversity also may contribute to long-term reduction of productivity in a cranberry field.

Native to Asia, T. formosana is now used in the United States as an ornamental border plant in woodland and shade gardens. A T. formosana var. stolonifera plant showing chlorosis and mild mosaic symptoms obtained from a commercial grower in Columbia County, Oregon tested positive for potyvirus by ELISA using our genus Potyvirus broad spectrum reacting PTY-1 Mab (3). Electron microscopic examination of negatively stained leaf-dip preparations from symptomatic leaves showed a mixture of two sizes of flexuous rod-shaped particles, approximately 700 nm long (resembling potyviruses) and 470 nm long (resembling potexviruses). Total RNA extracts from symptomatic leaves were used in reverse transcription (RT)-PCR assays with potyvirus- or potexvirus-specific primers. The degenerate primers for the genus Potyvirus (2) direct the amplification of approximately 1,600-bp fragments from the 3' terminus of most potyviruses. Overlapping potexvirus cDNA clones were generated using degenerate genus Potexvirus replicase primers, and later, virus-specific primers in 3' RACE (4). The RT-PCR amplified fragments were cloned and sequenced. Analysis of the 1,688 nt potyvirus sequence (GenBank Accession No. AY864850) using BLAST showed highest identity with members of the Bean common mosaic virus (BCMV) subgroup of potyviruses. Pair-wise amino acid comparisons of the CP region of the new potyvirus showed 78% identity to strains of Bean common mosaic necrosis virus, 77% identity with Soybean mosaic virus and Ceratobium mosaic virus, 72 to 76% identity to strains of BCMV, and only 50 to 64% identity with 54 other potyviruses. Additionally, similar pairwise analysis of the CP nucleotide sequence and 3'NCR of the new potyvirus generally revealed the same identity trend as described for the CP amino acid sequences, albeit with the highest nucleotide identities at less than 73% for CP and less than 66% for the 3'NCR. These results suggest that this virus is a new species in the genus Potyvirus (1), which we have tentatively named Tricyrtis virus Y (TrVY). BLAST analysis of the 3' terminal 3,010 nt potexvirus sequence (GenBank Accession No. AY864849) showed 89% nucleotide identity with Lily virus X (LVX). Pairwise amino acid comparisons of the putative gene products revealed 98, 95, 94 and 99% identity with LVX TGBp1, TGBp2, TGBp3-like, and CP, respectively, and 97% identity with the 108 nt 3'NCR. Homology with other members of the genus Potexvirus was less than 50% for these corresponding genes and gene products. ELISA and RT-PCR analysis for these two viruses in toad lily plants obtained from a grower in Illinois also revealed the presence of TrVY in three of seven cultivars and LVX coinfecting only one of the plants. The standard propagation method for T. formosana is plant division, which along with mechanical contact, provides efficient means for spread of both viruses. To our knowledge, this is the first description of this potyvirus and the first report of any potyvirus in T. formosana. LVX has been reported in Lilium formosanum, but to our knowledge, this is also the first report of LVX in T. formosana.

Accurate, precise, and reproducible disease assessment is needed for monitoring epidemics and disease response in breeding material. The objective of this study was to assess reproducibility of image analysis (IA) for measuring severity of canker symptoms and to compare this to visual assessments made by three visual raters (VR1-3) for various symptom types (lesion numbers, % area necrotic, and % area necrotic+chlorotic), and to assess inter- and intra-VR reproducibility. Digital images of 210 citrus leaves with a range of symptom severity were assessed on two separate occasions. IA was more precise than VRs for all symptom types (inter-assessment correlation coefficients, r, for lesion numbers by IA = 0.99, by VRs = 0.89 to 0.94; for %, r for % area necrotic+chlorotic for IA = 0.97 and for VRs = 0.86 to 0.89; and r for % area necrotic for IA = 0.96 and for VRs = 0.74 to 0.85). Accuracy based on Lin's concordance coefficient also followed a similar pattern, with IA being most consistently accurate for all symptom types (bias correction factor, C sub(b) = 0.99 to 1.00) compared to visual raters (C sub(b) = 0.85 to 1.00). Lesion number was the most reproducible symptom assessment (Lin's concordance correlation coefficient, p sub(c), = 0.76 to 0.99), followed by % area necrotic+chlorotic (p sub(c) = 0.85 to 0.97), and finally % area necrotic (p sub(c) = 0.72 to 0.96). Based on the "true" value provided by IA, precision among VRs was reasonable for number of lesions per leaf (r = 0.88 to 0.94), slightly less precision for % area necrotic+chlorotic (r = 0.87 to 0.92), and poorest precision for % area necrotic (r = 0.77 to 0.83). Loss in accuracy was less, but showed a similar trend with counts of lesion numbers (C sub(b) = 0.93 to 0.99) which was more consistently accurately reproduced by VRs than either % area necrotic (C sub(b) = 0.85 to 0.99) or % area necrotic+chlorotic (C sub(b) = 0.91 to 1.00). Thus, visual raters suffered losses in both precision and accuracy, with loss in precision estimating % area necrotic being the greatest. Indeed, only for % area necrotic was there a significant effect of rater (a two-way random effects model ANOVA returned a P 20% area (e.g., 25, 30, 35, 40, etc.), yet VRs were prepared to estimate disease of <1% area, and at 1% increments up to 20%. There was a linear relationship between actual disease (IA assessments) and VRs. IA appears to provide a highly reproducible way to assess canker-infected leaves for disease, but symptom characters (symptom heterogeneity, coalescence of lesions) could lead to discrepancies in results, and full automation of the system remains to be tested.

Antibiotic-free broiler chicken production systems are known to suffer from frequent outbreaks of necrotic enteritis due in part to pathogenic type A Clostridium perfringens. Hop (Humulus lupulus) bitter acids are known to possess potent antimicrobial activity. Lupulone was evaluated for in vivo antimicrobial activity to inhibit C. perfringens in a chick gastrointestinal colonization model. METHODS: Using a week-2 per os inoculated C. perfringens chicken colonization model, C. perfringens counts in mid-intestinal and caecal contents were compared between chickens administered lupulone at 62.5, 125 and 250 ppm in drinking water versus 0 ppm control. RESULTS: At day 22, post-hatch intestinal C. perfringens counts of lupulone-treated chickens were significantly lower (P < 0.05) than water-treated control groups in both jejunal and caecal sampling sites across all lupulone dosages tested. CONCLUSIONS: Lupulone administered through water inhibits gastrointestinal levels of inoculated pathogenic clostridia within the chicken gastrointestinal tract. Lupulone was effective within the chemically complex mixture of material within the gastrointestinal tract, thereby making this agent a target of further research as an antibiotic alternative for this and possibly other intestinal infections.

A more humane potency test is desired, and this study provides preliminary data in support of a serological assay that correlates post-vaccination antitoxin titers of guinea pigs to vaccine efficacy in mink. Mink and guinea pigs were injected with varying dilutions of a vaccine containing C. botulinum type C toxoid. Blood samples were collected from each animal prior to challenging the mink with type C toxin. Serum antitoxin titers of mink and guinea pigs were measured by a mouse protection test, and the results were compared to the outcome of the toxin challenge in mink. A dose-dependent antitoxin response was observed in guinea pigs vaccinated with the critical dilutions of vaccine bracketing the minimum protective dose in mink. These preliminary data suggest that it may be possible to correlate post-vaccination antitoxin titers in guinea pigs to vaccine efficacy in mink. This correlation could be used as the basis for a more humane potency test for C. botulinum type C toxoids.

Mutants of this strain are available that are deficient in the production of alternan, dextran, or both. Another mutant of NRRL B-1355, strain R1510, produces an insoluble glucan in place of alternan and dextran. To test the effect of exopolysaccharide production on biofilm formation, these strains were cultured in a biofilm reactor. All strains grew well as biofilms, with comparable cell densities, including strain NRRL B-21414, which produces neither alternan nor dextran in planktonic cultures. However, the exopolysaccharide phenotype clearly affected the appearance of the biofilms and the sloughed-off biofilm material produced by these biofilms. For all strains, soluble glucansucrases and soluble polysaccharides produced by biofilm cultures appeared to be similar to those produced by planktonic cultures. Biofilms from all strains also contained insoluble polysaccharides. Strain R1510 biofilms contained an insoluble polysaccharide similar to that produced by planktonic cultures. For most other strains, the insoluble biofilm polysaccharides resembled a mixture of alternan and dextran.

Thus, watershed-level models such as the Soil and Water Assessment Tool (SWAT) are increasingly used to forecast effects of land management changes on downstream water quality. With the generalization in scale, the question of effect of generalization in input data arises. That is, to what extent does having field-level, daily input data for a watershed model aid in the ability to predict watershed-scale, water quality impacts. The study site, FD-36, is a 39.5 ha agricultural subwatershed of a long-term USDA-ARS study watershed in south central Pennsylvania. FD-36 is characterized by loamy soils with a substantial near-stream fragipan. Fifty percent of FD-36 includes 24 row-cropped fields from three independently managed farms. Two SWAT scenarios were simulated on FD-36 and compared with each other as well as with measured data over two 4-year periods (1997-2000 and 2001-2004). The high-resolution scenario modeled seasonal crop, fertilizer, and tillage events of each row-cropped field continuously over the 8-year period. The low-resolution scenario treated all row-cropped fields as the same generic crop (AGRR in SWAT). Flow depth predictions at the outlet were similar for the two SWAT scenarios. While both scenarios showed higher levels of soil water in the fragipan soils than the surrounding soils, the high-resolution scenario was able to identify field-to-field distinctions due to the increased detail in input data. In general, model results were more defined at the field-level under the high-resolution scenario and followed patterns expected from knowledge about soil science, hydrology, P transport, and the characteristics of the study watershed. However, the time spent collecting, understanding, entering, and error-checking input data required for the high-resolution scenario was on the order of months, while full data collection for the low-resolution scenario took several days. Results suggest that while detailed input data can enable the model to provide valuable water quality information, research efficiency during exploratory and initial problem-solving efforts might be maximized by using more easily obtained, although more general, data.

If the areas making the largest contributions to nutrient and microbial transport can be identified, it may be possible to institute site-specific management practices to reduce runoff nutrient and microbial transport. The objectives of this study were to: (1) measure selected feedlot soil properties and nutrient and microbial transport in runoff from various feedlot locations, (2) compare the effects of unconsolidated surface materials (USM) (loose manure pack) and consolidated subsurface materials (CSM) (compacted manure and underlying layers) on nutrient and microbial transport, and (3) determine if nutrient and microbial transport in runoff are correlated to selected feedlot soil characteristics. Simulated rainfall events were applied to 0.75 m wide by 2 m long plots. No significant differences (P < 0.05) in feedlot soil characteristics or nutrient transport in runoff were found between USM and CSM. However, concentrations of E. coli were significantly greater in the USM than the CSM. Pen location was found to significantly influence feedlot soil measurements of Bray-1 P, calcium, chloride, copper, electrical conductivity (EC), loss on ignition, organic N, phosphorus, potassium, sodium, sulfur, total N (TN), water-soluble P, and zinc. Runoff measurements of dissolved phosphorus (DP), EC, andNH4-N were significantly influenced by pen location and were correlated to selected feedlot soil characteristics. Thus, it may be possible to estimate DP, EC, and NH sub(4)-N in runoff from selected feedlot soil parameters.

Due to many of the processes involved in the manual- or autocalibration of model parameters and the knowledge of realistic input values, calibration can become difficult. An autocalibration-sensitivity analysis procedure was embedded in SWAT version 2005 (SWAT2005) to optimize parameter processing. This embedded procedure is applied to six small-scale watersheds (subwatersheds) in the central Texas Blackland Prairie. The objective of this study is to evaluate the effectiveness of the autocalibration-sensitivity analysis procedures at small-scale watersheds (4.0-8.4ha). Model simulations are completed using two data scenarios: (1) 1 year used for parameter calibration; (2) 5 years used for parameter calibration. The impact of manual parameter calibration versus autocalibration with manual adjustment on model simulation results is tested. The combination of autocalibration tool parameter values and manually adjusted parameters for the 2000-2004 simulation period resulted in the highest E sub(N) sub(S) and R super(2) values for discharge; however, the same 5-year period yielded better overall E sub(N) sub(S), R super(2) and P-values for the simulation values that were manually adjusted. The disparity is most likely due to the limited number of parameters that are included in this version of the autocalibration tool (i.e. Nperco, Pperco, and nitrate). Overall, SWAT2005 simulated the hydrology and the water quality constituents at the subwatershed-scale more adequately when all of the available observed data were used for model simulation as evidenced by statistical measure when both the autocalibration and manually adjusted parameters were used in the simulation.

In replicated trials, young, mated, host-deprived C. marginiventris females were exposed to three Spodopteraexigua (Huebner) (Lepidoptera: Noctuidae) early instar larvae, one at a time, in Petri dish arenas, and observed as they stung these hosts once, twice, or thrice. The average amount of time that elapsed between stinging a host ranged from a minimum of 3 min, when females were exposed to unstung hosts, to a maximum of 8-11 min when females were exposed to previously stung hosts. Sting frequency had no effect on the yield of C. marginiventris progeny; approximately 90% of hosts, in all treatment groups, yielded a parasitoid mature larva, which spun a cocoon. No hosts yielded more than one parasitoid. The percentage of adult female progeny tended to increase with sting frequency; hosts that were stung thrice yielded 60% female C. marginiventris adults. The production of female progeny may depend on the egg allocation pattern of C. marginiventris females as well as the competitive interactions between siblings developing inside a shared host. This study suggests that S. exigua larvae can sustain 2-3 stings without diminishing their ability to yield a C. marginiventris mature larva. Provisioning enclosures with enough hosts to exceed the daily (per capita) oviposition rate of C. marginiventris females might limit the repeated stinging of the same hosts.

(Hymenoptera: Braconidae). Under standard laboratory conditions, water did not extend longevity in the absence of sugar in three out of four comparisons, nor did it extend longevity with access to nectar. Cotesia glomerata lived 2-3 days when given water or nothing, 8-15 days when given buckwheat (Fagopyrum esculentum Moench) nectar daily with or without water, and 23-26 days when given a 50% sucrose solution. The lifespan of C. glomerata fed flowers every other day was one-third shorter than that of C. glomerata fed flowers every day, but this difference was not statistically significantly. Only minimal benefits occurred when flowers were given every 3 days.

A field and laboratory study of urediniospore viability was conducted to determine the potential of using infected plant material for redistribution of inoculum into new areas. To better understand the life history of P. j. solstitialis, urediniospore viability was measured during the summer and fall when the host plant is usually senescent. Latent period (time from inoculation to pustule eruption) after field and laboratory inoculations was measured in order to determine the potential number of urediniospore generations that occur per year. Viability of urediniospores stored in the laboratory gradually declined over a period of 10 weeks; spore hydration increased germination. Based on the results obtained in this study, introductions of harvested infected plant material would have to be done quickly to offset losses in urediniospore viability. Urediniospore viability in the field decreased exponentially 86% near the coast and 97% in the Central Valley three weeks after production, and was negligible (0-0.2%) thereafter. Latent period ranged from four to five weeks at cool winter temperatures to two to three weeks at warm summer temperatures in both the laboratory and field. Results of this study suggest that urediniospores are not likely to remain viable through the summer and fall dry season. Teliospores, therefore, serve as the inoculum source when YST seedlings germinate in the winter. Approximately six urediniospore generations can be expected to occur each year in central-northern California under suitable conditions for disease.

Its psyllid vector, Diaphorina citri Kuwayama, has spread to Texas and Mexico, thus threatening the future of citrus production elsewhere in mainland North America. Even though sensitive diagnostic methods have been developed for detection of the causal organisms, Candidatus Liberibacter spp., the pathogen cannot be detected consistently in plants until symptoms develop, presumably because of low titer and uneven distribution of the causal bacteria in nonsymptomatic tissues. In the present study, TaqMan based real-time quantitative polymerase chain reaction methodology was developed for detection of 'Ca. L. asiaticus' in D. citri. Over 1,200 samples of psyllid adults and nymphs, collected from various locations in Florida, from visually healthy and HLB symptomatic trees at different times of the year were analyzed to monitor the incidence and spread of HLB. The results showed that spread of 'Ca. L. asiaticus' in an area may be detected one to several years before the development of HLB symptoms in plants. The study suggests that discount garden centers and retail nurseries may have played a significant role in the widespread distribution of psyllids and plants carrying HLB pathogens in Florida.

Little is known regarding plant defense signaling pathways that limit nematode parasitism during a compatible interaction. Therefore, we utilized Arabidopsis thaliana mutants perturbed in salicylic acid (SA) biosynthesis or signal transduction to investigate the role of SA in inhibiting parasitism by the beet cyst nematode Heterodera schachtii. We determined that SA-deficient mutants (sid2-l, pad4-l, and NahG) exhibited increased susceptibility to H. schachtii. In contrast, SA-treated wild-type plants showed decreased H. schachtii susceptibility. The npr1-2 and npr1-3 mutants, which are impaired in SA signaling, also showed increased susceptibility to H. schachtii, whereas the npr1-suppressor mutation mil showed decreased susceptibility. Constitutive pathogenesis-related (PR) gene-expressing mutants (cpr1 and cpr6) did not show altered susceptibility to H. schachtii; however, constitutive PR gene expression was restricted to cpr1 shoots with wild-type levels of PR-1 transcript present in cpr1 roots. Furthermore, we determined that H. schachtii infection elicits SA-independent PR-2 and PR-5 induction in wild-type roots, while PR-1 transcript and total SA levels remained unaltered. This was in contrast to shoots of infected plants where PR-1 transcript abundance and total SA levels were elevated. We conclude that SA acts via NPR1 to inhibit nematode parasitism which, in turn, is negatively regulated by SNI1. Our results show an inverse correlation between root basal PR-1 expression and plant susceptibility to H. schachtii and suggest that successful cyst nematode parasitism may involve a local suppression of SA signaling in roots.

Acute disease is associated with C. jejuni invasion of the intestinal epithelium. Further, maximal host cell invasion requires the secretion of proteins termed Campylobacter invasion antigens (Cia). As bile acids are known to alter the pathogenic behavior of other gastrointestinal pathogens, we hypothesized that the virulence potential of Campylobacter may be triggered by the bile acid deoxycholate (DOC). In support of this hypothesis, culturing C. jejuni with a physiologically relevant concentration of DOC significantly altered the kinetics of cell invasion, as shown by gentamicin protection assays. In contrast to C. jejuni harvested from Mueller-Hinton (MH) agar plates, C. jejuni harvested from MH agar plates supplemented with DOC secreted the Cia proteins, as judged by metabolic labeling experiments. DOC was also found to induce the expression of the ciaB gene, as determined by beta -galactosidase reporter, real-time reverse transcription-PCR, and microarray analyses. Microarray analysis further revealed that DOC induced the expression of virulence genes (ciaB, cmeABC, dccR, and tlyA). In summary, we demonstrated that it is possible to enhance the pathogenic behavior of C. jejuni by modifying the culture conditions. These results provide a foundation for identifying genes expressed by C. jejuni in response to in vivo-like culture conditions.

Agricultural biopolymers are usually mixtures of several compounds; however, high-temperature processing can cause unwanted consequences such as decomposition, gas generation, and phase-separation. This report introduces a new technology to form biodegradable polymer composites that can replace existing petroleum-based polymers. With this newly developed process, polymer composites are produced at room temperature. During the process, micrometer-scale raw materials are coated with zein, which has strong adhesive properties, and are then compressed to form a rigid coherent material. Since this technique does not require purification of the raw materials, various types of compounds can be used as component materials. In this report, wheat protein, gluten, was used as a matrix material. The compressive yield strength of the product formed from gluten is ca. 40 MPa, comparable to that of polypropylene.

GC-EAD analysis of the headspace volatiles of bark tissue samples from 0- and 24-h-old fully girdled (stressed) ash trees showed that the latter had elevated sesquiterpene levels. Six of the elevated compounds consistently elicited antennal responses by both male and female A. planipennis. Five of the antennally active compounds were identified as a-cubebene, a-copaene, 7-epi-sesquithujene, trans-b-caryophyllene, and a-humulene (a-caryophyllene). The sixth EAD-active compound remains unidentified. We monitored capture of adult A. planipennis on traps baited with several combinations of ash tree volatiles. Treatments included two natural oil distillates (Manuka and Phoebe oil) that were found to contain, respectively, high concentrations of four and five of the six antennally active ash bark volatiles. A four-component leaf lure developed by the USDA Forest Service and Canadian Forest Service was also tested. In three separate field studies, Manuka oil-baited traps caught significantly more adult beetles than unbaited traps. Lures designed to release 5, 50, and 500 mg of Manuka oil per day all caught more insects than unbaited traps. In a field test comparing and combining Phoebe oil with Manuka oil, Phoebe oil-baited traps caught significantly more beetles than either Manuka oil-baited traps or unbaited traps. We hypothesize that the improved attractancy of Phoebe oil to A. planipennis over Manuka oil is caused by the presence of the antennally active sesquiterpene, 7-epi-sesquithujene.

The manner in which multiple pathogens interact is not always straightforward, however. Bordetella bronchiseptica and porcine respiratory coronavirus (PRCV) are respiratory pathogens of pigs whose relatives, B. pertussis and the SARS virus, cause respiratory disease in humans. In an initial experiment, the effect of coinfection of PRCV and B. bronchiseptica was examined in thirty, 4-week-old pigs (10 pigs/group) that were infected with either PRCV or B. bronchiseptica, or both PRCV and B. bronchiseptica. An additional 10 pigs served as sham infected controls. Five pigs from each group were euthanized at 4 and 10 days post-infection. Gross and histopathological lung lesions were more severe in the coinfected group as compared to the groups infected with B. bronchiseptica or PRCV alone. In order to investigate the potential role of proinflammatory cytokines in disease severity after coinfection, a second experiment was performed to examine cytokine transcription in alveolar macrophages from single and dually infected pigs. A total of 48 pigs were divided equally into groups as above, but 4 pigs from each group were euthanized at 1, 4 and 10 days post-infection. Coinfected pigs showed a greater and more sustained transcription of proinflammatory cytokines, especially IL-6 and MCP-1, than pigs infected with either PRCV or B. bronchiseptica alone. Thus, there appears to be a synergistic effect between PRCV and B. bronchiseptica with regards to proinflammatory cytokine transcription that may partially explain the increased severity of pneumonia in coinfected pigs.

The temporal variability adjustment between CLM and AMSR-E data was conducted for annual and seasonal periods for 2003 in the Little River region, GA. The results showed that the statistical correction techniques improved AMSR-E's limited temporal variability as compared to ground-based measurements. The regression slope and intercept improved from 0.210 and 0.112 up to 0.971 and -0.005 for the non-growing season. The R super(2) values also modestly improved. The Moderate Resolution Imaging Spectroradiometer (MODIS) Leaf Area Index (LAI) products were able to identify periods having an attenuated microwave brightness signal that are not likely to benefit from these statistical correction techniques.

Objectives of these studies were to determine whether more larvae were produced in popcorn than in field corn and to determine how popcorn influenced female oviposition and larval distribution in neighboring field corn. Two varieties of popcorn (M140, 105d and M3374Y, 118d), one mixture of popcorn (50% 105d and 50% 118d), and field corn (DK580, 108d) were evaluated. Number of egg masses, eggs per egg mass, and larvae were significantly higher in popcorn compared with field corn. Moth oviposition and larval distribution were evaluated using 105d popcorn embedded in several cornfields across Iowa. The row of field corn adjacent to popcorn had significantly more larvae compared with background field corn. In larger field experiments, O. nubilalis larval survival after overwintering was significantly different, with 2.2-18.7 times more O. nubilalis larvae surviving in popcorn than field corn. The potential use of popcorn as an O. nubilalis refuge for genetically engineered corn is considered.

A chronology of outbreak years was constructed from historic records, research papers, newspapers, and other sources of information. Historic climate data for the region included annual and mean monthly temperature and precipitation, in addition to Palmer drought severity index (PDSI) values estimated from tree rings. Classification and regression tree analysis (CART) was used to identify those climate factors most important for predicting historic spruce beetle outbreaks. The factors identified by the best CART model included mean December temperature, mean September temperature 1 yr before outbreak years, the mean estimated PDSI value of the 5-yr period before outbreak years, and mean October precipitation. The resulting model correctly classified nonoutbreak and outbreak years 67 and 70% of the time, respectively.

Traps were placed in experimental collard and cowpea field plots in Charleston, SC, and in commercial organic fields of spring cantaloupe and watermelon in the Imperial Valley, CA. The exotic parasitoid Eretmocerus emiratus Zolnerowich and Rose was released in Imperial Valley fields to ensure parasitoid populations would be present. Bemisia adults were trapped in the greatest numbers on the upper surface of horizontally oriented sticky traps in melon fields. In contrast, the lower trap surfaces consistently captured more Eretmocerus than upper surfaces. Female parasitoids were trapped in greater numbers than males, especially on the lower trap surfaces. Progeny of released exotic Eretmocerus greatly outnumbered native E. eremicus Rose and Zolnerowich and Encarsia spp. on traps. Throughout the season, the trend of increasing numbers of Eretmocerus on traps parallelled the increase in numbers of whiteflies. Over the season, 23-84% of all B. tabaci fourth instars were visibly parasitized by Eretmocerus. The numbers of Eretmocerus caught by traps in cantaloupe were similar in trend to numbers on leaf samples in melons, but not with those in watermelon, where whitefly populations were lower. Parasitoid numbers were low in collard and cowpea samples, and no trend was observed in numbers of parasitoids captured on traps and numbers on leaves for these two crops. Overall, there were no significant correlations between sticky trap catches of parasitoids and numbers of parasitized whiteflies on leaf samples in any test fields. Nevertheless, sticky traps placed within crops may be useful for observing trends in whitefly parasitoid populations at a particular site and for detecting parasitoids at specific locations.

This method readily distinguishes C. jejuni from C. coli, has a resolving power comparable to that of multilocus sequence typing (MLST), is applicable to mixtures, and is highly automated. The strain typing approach is based on high-performance mass spectrometry, which "weighs" PCR amplicons with enough mass accuracy to unambiguously determine the base composition of each amplicon (i.e., the numbers of A's, G's, C's, and T's). Amplicons are derived from PCR primers which amplify short (<140-bp) regions of the housekeeping genes used by conventional MLST strategies. The results obtained with a challenge panel that comprised 25 strain types of C. jejuni and 25 strain types of C. coli are presented. These samples were parsed and resolved with demonstrated sensitivity down to 10 genomes/PCR from pure isolates.

Very little is known about the boundaries of microbial communities in moving bodies of water so this study was undertaken to find the limits of distribution of some bacteria, focusing on enteric organisms. The presence of Salmonella, Campylobacter, and Enterococcus spp. and the antimicrobial resistance phenotypes carried by these organisms was evaluated for the Upper Oconee River basin, a small river in the lower Piedmont of northeastern Georgia, USA. Samples were obtained from 83 sites during a 3-h period on a spring day (April 2005) in an approximately 30 x 20 km region. Campylobacter spp. was isolated at 12 sites. The Campylobacter isolates from three sites were resistant to tetracycline. Of the five short-variable region (SVR) subtypes of Campylobacter that were found, three were found at more than one site, two types were found twice, and one subtype was found three times. Enterococcus was isolated at 71 sites. E. casseliflavus was the most common species. Based on species identification and antimicrobial resistance patterns, 24 types of Enterococcus were found. Salmonella was isolated from 62 sites. Of the 19 Salmonella serovars that were isolated, serovar Muenchen accounted for about 20% of the isolates. The next three most common serovars isolated, Rubislaw, Hartford, and Give, accounted for about 44% of the river isolates. Antimicrobial resistance profiling offered limited differentiation of Salmonella isolates because only seven isolates were resistant to any antimicrobial. The sites at which Salmonella, Campylobacter, or Enterococcus were isolated did not correlate with each other or with the total coliform number or Escherichia coli count for the site. However, isolates of some of the same species and type occurred in clusters that were restricted to areas within 5 to 6 km.

We examined how changing landscape structure from 26 years of forest management and wildfire disturbances influenced population size and spatial dispersion of male Kirtland's warblers within their restricted breeding range in northern Lower Michigan, USA. The male Kirtland's warbler population was six times larger in 2004 (1,322) compared to 1979 (205); the change was nonlinear with 1987 and 1994 identified as significant points of change. In 1987, the population trend began increasing after a slowly declining trend prior to 1987, and the rate of increase appeared to slow after 1994. Total amount of suitable habitat and the relative area of wildfire-regenerated habitat were the most important factors explaining population trend. Suitable habitat increased 149% primarily due to increasing plantations from forest management. The relative amount and location of wildfire-regenerated habitat modified the distribution of males among various habitat types, and the spatial variation in their abundance across the primary breeding range. These findings indicate that the Kirtland's warbler male population shifted its use of habitat types temporally and spatially as the population increased and as the relative availability of habitats changed through time. We demonstrate that researchers and managers need to consider not only habitat quality, but the temporal and the spatial context of habitat availability and population levels when making habitat restoration decisions.

The objectives of this study were to survey coccinellids in various habitats in South Dakota to better characterize the current coccinellid fauna, determine the extent of exploitation by invasive coccinellids, and possibly identify refuge habitats of previously common coccinellid species. Overall, 2827 coccinellids, comprising 23 species, were collected on yellow sticky traps in field and woody habitats and during timed visual searches in field crops. Adalia bipunctata was found during additional sampling in Butte County in western South Dakota. However, it was not present in samples from eastern and central parts of the state, which is consistent with previous findings that this species is absent from those areas. Coccinella transversoguttata richardsoni and C. novemnotata were absent at all sites sampled. Scymnus kansanus Casey was collected for the first time in South Dakota among arboreal habitats. Harmonia axyridis (Pallas) expanded its geographic range into central South Dakota by 2002 and western South Dakota by 2004. Invasiveness of H. axyridis and C. septempunctata was evident by their presence in a wide variety of habitats surveyed, dominance of larval coccinellid assemblages, and predation upon non-target species of aphids. Harmonia axyridis was the most abundant larval coccinellid in maize and C. septempunctata was the most abundant larval coccinellid in intercropped wheat-alfalfa. Harmonia axyridis preyed upon Stegophylla quercicola (Monell), Aphis nerii Boyer de Fonscolombe, and Aphis asclepiadis Fitch in the field. Both H. axyridis and C. septempunctata preyed upon Hyalopterus pruni (Geoffroy) in the field.

Several protein kinases get activated in plants in response to osmotic stress and the stress hormone abscisic acid (ABA). Among these is a superfamily of sucrose non-fermenting protein kinase genes (SnRK2). This review focuses on the developments related to the activity, substrates, interacting proteins and gene regulation of SnRK2 gene family members. Reversible phosphorylation as a crucial regulatory mechanism turns out to be a rule rather than an exception in plant responses to abiotic stress. Nine out of thirteen bZIP transcription factors (ABI5/ABF/AREB family) share the recognition motif, R-Q-X-S/T, suggesting that likely SnRK2 kinases have a major role in regulating gene expression during hyperosmotic stress.

For species that have a prolonged parent-offspring relationship and that live solitary adult lives, social learning between parents and offspring may be a dominant form of learning. If parent-offspring learning is a dominant avenue for acquiring behavior or if behavior is inherited, then behaviors that confer significant fitness advantages should lead to subpopulations of genetically related individuals with similar behavioral patterns. We investigated whether food-conditioning behavior in black bears (Ursus americanus) is inherited or learned via parent-offspring social learning. We combined genetic data with behavioral data for 116 black bears from Lake Tahoe Basin, Nevada, and Yosemite National Park, California. We categorized individual bears as food-conditioned or non-food-conditioned based on their behavior over a several-year period of intensive study at each site. We compared levels of relatedness, based on microsatellite DNA genotyping, within and between these groups and compared behavior between 9 mother-offspring pairs determined through genetic analysis of maternity. Based on 4 separate analyses of the data there was little evidence that food-conditioning behavior in black bears partitioned along related lineages, indicating that the acquisition of food conditioning behavior was not solely a function of social learning or inheritance.

Litter and soil samples were collected from 10 farms with more than 40 years of broiler production and from wooded sites adjacent to fields and were analyzed for P and metal contents. Averaged over farms, total P and metal concentrations in the litter were 12.8g kg-1 P and 332, 350, 334, and 2.93mg kg-1 Cu, Zn, Mn, and As, respectively. Surface (0-15cm) soil pH values were greater than (5.7-6.4) the 0- to 15-cm depth at wooded sites (3.5-4.3). Surface soil Bray 1 P values (149-796mg kg-1) in amended fields were greater than wooded sites (4.4-17mg kg-1). The 1N nitric acid (HNO3)-extractable metal concentrations were higher in amended soils than in wooded areas and were 7.7-32, 5.7-26, 12.3-71, and 0.6-3.0mg kg-1 for Cu, Zn, Mn, and As, respectively, compared to 0.76-14, 4.6-22, 1.6-70, and 0.14-0.59mg kg-1 for the same metals, respectively, in wooded areas. Results from this study demonstrated that long-term broiler litter applications have altered the chemical properties of the Coastal Plain soils of the Maryland Eastern Shore. Metal concentrations were low in the surface layer of amended fields and typically decreased with depth. Phosphorus additions rather than metals are most likely to contribute to the degradation of the Chesapeake Bay watershed.

Above a critical heating threshold, however, its destruction occurs. Although the temperature thresholds for repellency destruction are relatively well established, little is known about the specific changes in the soil organic matter that are responsible for repellency destruction. Here we report on the analysis of initially water repellent surface soil samples (Dystric Cambisol, 0-5 cm depth) by transmission Fourier Transform Infrared (FTIR) spectroscopy analysis before and after destruction of its water repellency by heating to 225 degree C in order to investigate heating-induced changes in soil organic matter (SOM) composition. Although assignment of absorption bands is made difficult by overlapping of some bands, it was possible to distinguish bands relevant for hydrophobicity of SOM in the soil before heat treatment. The most significant decrease in absorbance following water repellency destruction took place in the frequency area corresponding to stretching vibrations of aliphatic structures within SOM. The results suggest that besides a general decrease of SOM content during heating, the loss of soil water repellence is primarily caused by the selective degradation of aliphatic structures.

For the EU, agriculture is seen as a means of sustaining the countryside; keeping it attractive to tourists and prospective residents. Farmers are stewards of the land and as such a key to rural development. For the US, agriculture and the environment are seen in potential conflict. Most of the expenditure on conservation goes to keeping environmentally sensitive cropland out of production. At the national level at least, the appeal of the countryside is not seen as a means to rural development, so that conservation programs tend to be seen as a threat to rural development by reducing the use of local off-farm services. Part of the difference in viewpoint may stem from the greater socio-cultural significance of agricultural landscapes in the EU. However, recent research in the US suggests that landscape is important in attracting new rural residents and visitors and there is growing recognition on both sides of the Atlantic that the natural environment helps shape rural growth. More research is needed on the relationship between the environment and rural development as unsupported assumptions seem to underlie policies in both regions.

Merlot) were made by a commercial winery to examine the effects of seed removal at 10°Brix on the extraction of proanthocyanidins during fermentation. Seeds were removed at the point when they fell to the bottom of the fermenter, and were thus easily removed during regular pump-over operations. Proanthocyanidin extraction was compared to wine made from traditional winemaking regime in which no seed removal occurred. Proanthocyanidin differences observed in the wines were minor. The control wine contained a slightly higher percentage molar proportion of seed proanthocyanidins ((-)-epicatechin-3-O-gallate extension and terminal subunits), demonstrating higher seed tannin extraction, and the seed removed wine contained a higher percentage molar proportion of skin proanthocyanidin indicators ((-)-epigallocatechin extension subunits). Seed removed Merlot wines had higher concentrations of total anthocyanins. Minor differences in colour measurement values between the two wines were also observed. The control wine was slightly more orange (larger hue angle, h°), lighter (larger L* value), and more saturated (higher chroma value, C*) in colour. This appears to be the first paper to report the effects of early seed removal in Merlot winemaking, and demonstrates how winery tannin management techniques contribute to proanthocyanidin composition.

AN - 70414293; 18298071 AB - Peanuts respond to fungal infection by synthesizing phytoalexins, most of which are antibiotic stilbenes. The mechanism and dynamics of phytoalexin formation in the peanut have not been studied. One of the most popular peanut cultivars in the southeastern United States, Georgia Green, was investigated for its ability to produce phytoalexins in response to infection by soil fungal strains. The experimental design allowed for study of phytoalexin production in peanut kernels layer-by-layer. The layers were dissected from different depths of the kernel starting from the infected area down to healthier tissues. Six peanut phytoalexins, trans-resveratrol, trans-arachidin-1, trans-arachidin-2, trans-arachidin-3, trans-3-isopentadienyl-4,3',5'-trihydroxystilbene, and SB-1, were detected in the kernel slices and quantitated. All of the fungal strains triggered phytoalexin production; however, the composition of phytoalexins varied significantly by layer. After incubation for 24 h, tissues remote from the infected area produced almost exclusively trans-resveratrol, whereas closer to the infected area tissues synthesized all six phytoalexins. In all of the experiments, after 48 h of fungal growth, deeper layers produced all tested phytoalexins. There was a significant difference in phytoalexin production elicited by some fungal isolates. No association was observed between phytoalexin production and toxigenic potential of fungal strains that elicited the production in mature peanut kernels.

AN - 70410355; 18298069 AB - Aminomethylphosphonic acid (AMPA) is the most frequently detected metabolite of glyphosate in plants. The objective of this study was to determine if there is any correlation of metabolism of glyphosate to AMPA in different plant species and their natural level of resistance to glyphosate. Greenhouse studies were conducted to determine the glyphosate I 50 values (rate required to cause a 50% reduction in plant growth) and to quantify AMPA and shikimate concentrations in selected leguminous and nonleguminous species treated with glyphosate at respective I 50 rates. Coffee senna [ Cassia occidentalis (L.) Link] was the most sensitive ( I 50 = 75 g/ha) and hemp sesbania [ Sesbania herbacea (P.Mill.) McVaugh] was the most resistant ( I 50 = 456 g/ha) to glyphosate. Hemp sesbania was 6-fold and Illinois bundleflower [ Desmanthus illinoensis (Michx.) MacM. ex B.L.Robins. & Fern.] was 4-fold more resistant to glyphosate than coffee senna. Glyphosate was present in all plant species, and its concentration ranged from 0.308 to 38.7 microg/g of tissue. AMPA was present in all leguminous species studied except hemp sesbania. AMPA concentration ranged from 0.119 to 4.77 microg/g of tissue. Shikimate was present in all plant species treated with glyphosate, and levels ranged from 0.053 to 16.5 mg/g of tissue. Non-glyphosate-resistant (non-GR) soybean accumulated much higher shikimate than glyphosate-resistant (GR) soybean. Although some leguminous species were found to be more resistant to glyphosate than others, and there was considerable variation between species in the glyphosate to AMPA levels found, metabolism of glyphosate to AMPA did not appear to be a common factor in explaining natural resistance levels.

AN - 70276543; 18242864 AB - Selection pressure with the acaricide, amitraz was applied to a strain of Rhipicephalus (Boophilus) microplus (Canestrini) in 13 out of 18 generations, resulting in a 28.7-fold increase in resistance, indicating a shift in the phenotypic composition of the ticks, from a heterogenous mixture of both susceptible and resistant ticks when selection began to a homogenous composition of predominantly resistant ticks when selection ended. Resistant larvae of the last selected generation were infested on cattle three separate times at 20, 13, and 6 d (7 d intervals) before being dipped in a total immersion vat charged at 0.02, 0.044, and 0.096% active ingredient (AI) amitraz. There was a dose related, though not always significant, response to amitraz whereby each increase in concentration produced increased adverse effects. The number of ticks and index of fecundity (IF) of females recovered from cattle treated at 0.02 and 0.044% AI were not different from that of untreated ticks. However, female weight and egg mass weight of females recovered from cattle treated at 0.044% were lower than untreated females or females treated at 0.02% AI. All measured parameters obtained from ticks recovered from cattle treated at 0.096% AI were significantly lower than the untreated control group, but tick numbers and IF were not different from the other treated groups. At 0.02% AI the level of control was significantly lower (34.6%) than treatment at 0.096% AI (81.2%), while the level of control at 0.044% AI (57.6%) was intermediate between the other treated groups. Therefore, none of the amitraz treatments provided the required 99% control necessary for use in the U.S. Cattle Fever Tick Eradication Program, and the estimated line derived from regression analysis showed that a concentration of ca. 0.2% AI amitraz would be needed to achieve 99% control of the resistant ticks.

Our collections indicate that un-reported species such as G. radiata and H. trivolvis are established on Dominica, West Indies. We tested a limited number of M. tuberculata for rickettsial pathogens, Neorickettsia spp., but did not identify this agent. Three species of snails previously reported from Dominica, Biomphalaria glabrata (Say, 1818), Biomphalaria straminea (Dunker, 1848), and Thiara granifera (Lamarck, 1822), were not collected. Our data suggest that B. glabrata has not re-emerged as a prominent component of the freshwater snail fauna since it disappeared or was locally eradicated. In addition, previous reports of B. straminea were probably misidentifications of B. kuhniana, and some abnormally large specimens of M. tuberculata from Freshwater Lake could be misidentified as T. granifera. Our sampling was not adequate to demonstrate that T. granifera was absent from Dominica. We determined that B. kuhniana was not eradicated by previous molluscan control regimes. Additional studies on the relationships of freshwater snails in Dominica to helminths of animals and humans are needed to understand the public and veterinary health significance of these snails.

Mortality has progressed rapidly. Area affected increased 58% between 2005 and 2006 on the Mancos-Dolores Ranger District, San Juan National Forest, where it equaled nearly 10% of the aspen cover type. In four stands that were measured twice, incidence of mortality increased from 7-9% in 2002/2003 to 31-60% in 2006. Mortality generally decreased with increasing elevation over the primary elevation range of aspen and occurred on less steep slopes than healthy aspen. Slope-weighted mean aspects of aspen cover type were northern at low elevations and generally southern at high elevations. Relative frequency of mortality was generally highest on southern to western aspects. In 31 stands measured in detail, mortality ranged from 0 to 100% (mean 32%) and was negatively correlated with stand density (P=0.033). Size of trees affected was strongly correlated with amount of current mortality (P<0.001), and current mortality was skewed toward larger diameter classes. Density of regeneration was in a low range typical of undisturbed stands and did not increase with overstory mortality. Agents that typically kill mature trees in aspen stands were unimportant in this mortality. Instead, a group of interchangeable, usually secondary agents was most commonly associated with mortality, including Cytospora canker (usually caused by Valsa sordida), aspen bark beetles (Trypophloeus populi and Procryphalus mucronatus), poplar borer (Saperda calcarata), and bronze poplar borer (Agrilus liragus). The rapidity of mortality, mortality agents involved, and probably other causal factors distinguish this phenomenon from the long-term loss of aspen cover usually attributed to successional processes operating in an altered disturbance regime (and often exacerbated by ungulate browsing). Our data are consistent with a hypothesis that (a) predisposing factors include stand maturation, low density, southern aspects and low elevations; (b) a major inciting factor was the recent, acute drought accompanied by high temperatures, and; (c) contributing factors and proximate agents of mortality are the common biotic agents observed. On sites with poor regeneration and weak root systems, clones may die, resulting in the long-term loss of aspen forest cover.

Recent progress in separating soil and canopy temperatures from dual angle composite radiometric temperature measurements has encouraged the development of two-source (soil and canopy) approaches to estimating surface energy fluxes given observations of component soil and canopy temperatures. A Simplified Two-Source Energy Balance (STSEB) model has been developed using a ''patch'' treatment of the surface flux sources, which does not allow interaction between the soil and vegetation canopy components. A simple algorithm to predict the net radiation partitioning between the soil and vegetation is introduced as part of the STSEB patch modelling scheme. The feasibility of the STSEB approach under a full range in fractional vegetation cover conditions is explored using data collected over a maize (corn) crop in Beltsville Maryland, USA during the 2004 summer growing season. Measurements of soil and canopy component temperatures as well as the effective composite temperature were collected over the course of the growing season from crop emergence to cob development. Comparison with tower flux measurements yielded root-mean-square-difference values between 15 and 50 W m super(-) super(2) for the retrieval of the net radiation, soil, sensible and latent heat fluxes. A detailed sensitivity analysis of the STSEB approach to typical uncertainties in the required inputs was also conducted indicating greatest model sensitivity to soil and canopy temperature uncertainties with relative errors reaching ~30% in latent heat flux estimates. With algorithms proposed to infer component temperatures from bi-angular satellite observations, the STSEB model has the capability of being applied operationally.

Review and comparison of various approaches to segmentation of the land surface reveals common features, and permits development of a broad theoretical basis for segmentation and for characterization of segments and their boundaries. Within the context of defining landform units that maximise internal homogeneity and external differences, this paper introduces the concept of elementary forms (segments, units) defined by constant values of fundamental morphometric properties and limited by discontinuities of the properties. The basic system of form-defining properties represents altitude and its derivatives, constant values of which provide elementary forms with various types of homogeneity. Every geometric type of elementary form can be characterized by a defining function, which is a specific case of the general polynomial fitted function. Various types of boundary discontinuity and their connections and transformations into other types of morphological unit boundaries are analysed. The wealth of types of elementary forms and their boundaries is potentially unbounded and thus is sufficient to cover the real variety of landforms. Elementary forms in the basic set proposed here have clear potential for genetic and dynamic interpretation. A brief worked example documents the possibility of analytical computation of various models of ideal elementary forms for particular segments of landform. Ideal elementary forms can be considered as attractors, to which the affinity of surface segments can be measured by multivariate statistical methods. The use of the concept of elementary forms in landscape segmentation is promising and it could be adapted for elementary segmentation of various other spatial fields.

Seeds were collected from 67 open-pollinated trees from five provenances in the Yucatan Peninsula of Mexico and planted in three provenance/progeny trials in the state of Quintana Roo, Mexico, in order to characterize genetic variation in growth traits and for Hypsipyla resistance or recovery, and to assess the potential for genetic gain. Differentiation among provenances was found only for relative height growth rate (RHGR). The total years of apical attack by Hypsipyla grandella varied by a magnitude of 100% among families but showed little heritability. After 4 years, mean height per family ranged from 328 to 564cm, 160 to 381cm, and 253 to 390cm at each site. Although heritabilities for height were too low for cross-site selection, sufficient heritability (h sub(I) super(2)=0.26), additive genetic coefficients of variation (AGCV=22%), and type B genetic correlations (r sub(b) sub(() sub(f) sub())=0.74) for RHGR across the two sites with poorer growth indicated that this trait might be used as a surrogate. This would yield an estimated gain of about 17% for the best 15% of trees. At the site with better growth, there was sufficient heritability (h sub(I) super(2)=0.31) and AGCV (20%) for height at year 5 to obtain an estimated gain of 15% for the best 15% of trees. We suggest a selection strategy using the best germplasm from the best performing trial to exploit the resources on high quality sites, and the best material from the poorer sites for lower quality areas.

In 1998, seed collections were made from Spanish cedar in the Yucatan Peninsula, Mexico, for genetic conservation and tree improvement projects. Progeny from these collections were established in genetic trials at Bacalar, Noh Bec, and Zoh Laguna in the Yucatan. Survival at 2 years was 73.5% at Bacalar, 72% at Noh Bec, but only 20% after 6 months for several replicates at Zoh Laguna. Mean 2-year height, number of years of Hypsipyla attack on apical shoots (over 2 or 3 years) and total branching over 2 years, were 1.3m, 0.04 years, and 2.5 branches at Bacalar, and 1.9m, 0.35 years, and 1.6 branches at Noh Bec. Selection of the three best provenances (Escarcega, Bacalar, and Calakmul) would result in an estimated cross-site gain of 8.6% in 2-year height. Within-provenance, cross-site heritabilities for 2-year height, shoot borer attack, and branching were 0.1+/-0.02, 0.0+/-0.02, and 0.0+/-0.02, respectively. Single-site heritabilities for height at 2 years, shoot borer attack, and branching were 0.09+/-0.05, 0.02+ /-0.04, and 0.09+/-0.05 at Bacalar and 0.16+/-0.07, 0.0+/-0.06, and 0.0+/-0.07 at Noh Bec. Given the known advantage of rapid growth to avoid Hypsipyla damage over the long term and the stable performance of provenances across sites for growth traits, we recommend provenance selection over multiple trials to reduce the risk of serious damage by the insect. Good provenances and other suitable seed sources, as well as proper site selection and silvicultural practices, are important tools for increasing yields from plantations of C. odorata.

An 80 kW RFEF pilot plant system was used to process cider at flow rates of 1.5 and 1.9 l/min. Escherichia coli K12 in apple cider was exposed to electric field strengths of 20-30 kV/cm at frequencies of 21, 30, and 41 kHz. Treatment times varied from 140 to 420 [micro]s. Electrical energy costs were calculated using the measured voltages and currents. Energy balances were performed using the inlet and outlet temperatures. RFEF processing at an outlet temperature of 60 [deg]C reduced the population of E. coli by 4.8 log, whereas thermal processing at the same conditions had no effect. Varying the frequency between 21 and 41 kHz had no effect on the level of microbial inactivation; however, increasing the treatment time, field strength and outlet temperature enhanced inactivation. The inactivation data at 20 kV/cm and 60 [deg]C follow first order kinetics with a calculated D values of 74 [micro]s. The inactivation data are represented well by the electric field strength model; the calculated critical electric field strength, E sub(c, for 60 [deg]C was 4.0 kV/cm. The electrical energy for RFEF pasteurization was 260 J/ml. The electrical cost was $0.0050/l of apple cider. Processing temperature had the greatest influence on energy efficiency. A RFEF nonthermal process has been developed to pasteurize apple cider. The effect of varying processing conditions on energy efficiency was investigated and at the optimum condition, the electrical cost appears to be minor. In addition, the RFEF process can be correlated using first order kinetic models.)

Solution-state two-dimensional (2D) nuclear magnetic resonance (NMR) of this gel, produced directly in the NMR tube, provides an interpretable structural fingerprint of the polysaccharide and lignin components of the wall without actual solubilization, and without structural modification beyond that inflicted by the ball milling and ultrasonication steps. Since the cellulose is highly crystalline and difficult to swell, the component may be under-represented in the spectra. The method however provides a more rapid method for comparative structural evaluation of plant cell walls than is currently available. With the new potential for chemometric analysis using the 2D NMR fingerprint, this method may find application as a secondary screen for selecting biomass lines and for optimizing biomass processing and conversion efficiencies.

The objective of the project reported here was to estimate the cost of production that would be experienced by farmers on commercial production situations. Switchgrass was produced as a biomass crop on commercial-scale fields by ten contracting farmers located from northern North Dakota to southern Nebraska. Results showed a wide range of yields and costs across the five production years and ten sites, with an overall average cost of $65.86Mg super(-1) of biomass dry matter, and annualized yield of 5.0Mg ha super(-1). The low-cost half of the producers were able to produce at an average cost of $51.95Mg super(-1)over the 5-year period. When projected to a full 10-year rotation, their cost fell further to $46.26Mg super(-1). We conclude that substantial quantities of biomass feedstock could have been produced in this region at a cost of about $50Mg super(-1) at the farm gate, which translates to about $0.13/l of ethanol. These results provide a more reliable benchmark for current commercial production costs as compared to other estimates, which range from $25 to $100Mg super(-1).

We estimated production costs, profits, and energy budgets for three potential crop systems for the Upper Midwest: continuous corn with stover harvest, an alfalfa-corn rotation with stover harvest, and switchgrass. Production costs, profits, and on-farm energy use were greatest for continuous corn, less for alfalfa-corn, and least for switchgrass. Energy to transport crops was similar for all crop systems. Both energy used to produce ethanol and energy output in ethanol was greatest for continuous corn, less for alfalfa-corn, and least for switchgrass. Co-product energy output was 32% greater for alfalfa-corn than continuous corn and 42% greater than switchgrass. Net energy produced (outputs-inputs) was greatest for switchgrass, followed by continuous corn, and then alfalfa-corn. Efficiency of energy production (outputs/inputs) was greatest for switchgrass, followed by alfalfa-corn, and then continuous corn. Our analysis emphasizes tradeoffs among crop systems. Corn may produce high rates of ethanol and net energy, but will do so least efficiently and with the greatest erosion and N leaching. Corn may have the greatest production costs, but return the greatest profit. Comparatively, alfalfa-corn will produce less ethanol and net energy, but will do so more efficiently, and with less erosion and little N leaching. Production costs, but also profits, may be less for alfalfa-corn than continuous corn. Switchgrass may produce the most net energy and will do so most efficiently and with the least erosion, but will also yield the least ethanol. Nitrogen leaching will be less for switchgrass than corn, but greater than alfalfa-corn. Switchgrass may be the least expensive to produce, but may return a profit only if selling prices or yields are high.

AN - 70758217; 18488599 AB - The threat posed by exotic organisms to native systems has led to extensive research on exotic invaders, yet management of invasives has progressed relatively slowly. This is partly due to poor understanding of how exotic species management influences native organisms. To address this shortfall, we experimentally evaluated the efficacy of an invasives management tool for restoring native deer mouse (Peromyscus maniculatus) populations elevated by exotic species. The exotic insects, Urophora spp., were introduced in North America for biological control of the Eurasian invader, spotted knapweed (Centaurea maculosa), but instead of controlling C. maculosa, Urophora have become an important food resource that doubles P. maniculatus populations, with substantial indirect effects on other organisms. We hypothesized that herbicide suppression of Urophora's host plant would reduce the Urophora food resource and restore P. maniculatus populations to natural levels. Prior to treatment, mouse populations did not differ between controls and treatments, but following treatment, P. maniculatus were half as abundant where treatment reduced Urophora. Peromyscus maniculatus is insensitive to direct herbicide effects, and herbicide-induced habitat changes could not explain the P. maniculatus response. Treatment-induced reductions of the Urophora food resource offered the most parsimonious explanation for the mouse response: Multistate mark-recapture models indicated that P. maniculatus survival declined where Urophora were removed, and survival rates were more correlated with variation in population size than movement rates. Other demographic and reproductive parameters (sex ratios, reproductive status, pregnancy rates, and juvenile recruitment) were unaffected by treatment. These results suggest the Urophora biocontrol elevated P. maniculatus survival, and the herbicide treatment restored mouse populations by removing the exotic food and reducing survival. This work illustrates the importance of mechanistic understandings of community and population ecology for improving invasive species management.

AN - 70485454; 18396560 AB - Pasture management and broiler litter application rate are critical factors influencing the magnitude of nutrients being transported by runoff from fields. We investigated the impact of pasture management and broiler litter application rate on nutrient runoff from bermudagrass (Cynodon dactylon) pastures. The experiment was conducted on a Ruston fine sandy loam with a factorial arrangement on 21 large paddocks. Runoff water was collected from natural rainfall events from 2001 to 2003. Runoff water and soil samples were analyzed for nutrients and sediments. Runoff was generally greater (29%) from grazed than hayed pastures regardless of the litter application rate. There was greater inorganic N in the runoff from grazed paddocks when litter rate was based on N rather than P. The mean total P loss per runoff event for all treatments ranged from 7 to 45 g ha(-1) and the grazed treatment with litter applied on N basis had the greatest total P loss. Total dissolved P was the dominant P fraction in the runoff, ranging from 85% to 93% of the total P. The soluble reactive P was greater for treatments with litter applied on N basis regardless of pasture management. Runoff total sediments were greater for N-based litter application compared to those which received litter on P basis. Our results indicate that litter may be applied on N basis if the pasture is hayed and the soil P is low. In contrast, litter rates should be based on a P-basis if pasture is grazed.

A total of 140 beef heads obtained from a commercial processing line were inoculated with Escherichia coli O157:H7 on the cheek areas. Each head was exposed to a simulated preevisceration wash and then had antimicrobial wash treatments.

Electrolyzed oxidizing water and ozonated water reduced E. coli O157:H7 less than 0.50 log CFU/cm2. Hot water, lactic acid, and FreshFx could be used as decontamination washes for the reduction of E. coli O157:H7 on bovine head and cheek meat.

AN - 70480185; 18389698 AB - The goal of this study was to determine the prevalence of Listeria monocytogenes in sows slaughtered at a single Midwestern plant on two occasions (trial 1, n = 179 sows; trial 2, n = 160 sows). Fecal samples collected antemortem (trial 1) as well as animal tissues, and carcass swabs collected at the abattoir (trials 1 and 2) were analyzed. Eight isolates of L. monocytogenes were recovered from five samples that represented 0.18% of the total samples (n = 2,775). In trial 1, L. monocytogenes was detected in a tonsil sample (0.6%; 1 positive of 181 tonsils), in a carcass (0.6%; 1 positive of 179 carcasses), which was sampled prior to the organic rinse, and in two chopped meat block samples (1.2%; 2 positive of 165 samples). In trial 2, L. monocytogenes was only detected in a single chopped meat block sample (0.15%; 1 positive of 688 total samples). These data indicate the low prevalence of L. monocytogenes in the cull sow.

AN - 70366889; 18167041 AB - Ofloxacin (15 microg/mL) and acridine orange (5 microg/mL) induce mutagenicity by different mechanisms in the photosynthetic flagellate Euglena gracilis. The present study examined whether Pycnogenol (PYC; 5-100 microg/mL) or Ginkgo biloba extract (EGb 761; 5-100 microg/mL) could protect against the mutagenic effects of each of the mutagens and the potential mechanisms underlying such protection. The highest concentration of PYC and EGb 761 effectively reduced the mutagenic activity of both ofloxacin and acridine orange by more than 99% (p < 0.001). Using luminol-dependent photochemical methodology it was demonstrated that EGb 761 and PYC were effective antioxidants. In addition, as determined by spectrophotometry, PYC and EGb 761 bound acridine orange. Both PYC and EGb 761 have been shown to produce dual antimutagenic effects, as evidenced by both antioxidant and physicochemical properties. The findings suggest that EGb 761 and PYC would thus be suitable for future study, not only as antioxidants, but also as antimutagenic agents.

AN - 70361050; 17681655 AB - Many surface and ground waters in the continental US are contaminated with a variety of chemical pollutants, which are usually present in concentrations in the ppm and ppb range. The effects of these pollutants on coliform bacteria, which are prominent members of the aquatic flora, are poorly understood. Using a microtiter plate assay, isolates of Escherichia coli (from chicken intestine and fresh water), and an isolate of Klebsiella pneumoniae (from bovine milk) were exposed to varying concentrations of common pollutants over a 24 h period. The herbicides/pesticides simazine, atrazine, and diazinon; the VOCs trichloroethene and MTBE; the estrogens estradiol and estrone; and caffeine, all failed to inhibit bacterial growth at ppm levels. Only ethylene glycol, and the herbicide 2,4-D, significantly inhibited bacterial growth compared to controls. These results suggest that the replication of coliform bacteria in fresh waters is not adversely impacted by many common pollutants.

AN - 70336279; 18298742 AB - Food irradiation is a safe and effective method for inactivation of pathogenic bacteria, including Escherichia coli O157:H7, in meat, leafy greens, and complex ready-to-eat foods without affecting food product quality. Determining the radiation dose needed to inactivate E. coli O157:H7 in foods and the validation of new irradiation technologies are often performed through inoculation of model systems or food products with cocktails of the target bacterium, or use of single well-characterized isolates. In this study, the radiation resistance of 4 E. coli strains, 2 DNA repair deficient strains used for cloning and recombinant DNA technology (JM109 and DH5alpha) and 2 strains of serotype O157:H7 (C9490 and ATCC 35150), were determined. The D-10 values for C9490, ATCC 35150, JM109, and DH5alpha stationary phase cells suspended in Butterfield's Phosphate Buffer and irradiated at 4 degrees C were 229 (+/- 9.00), 257 (+/- 7.00), 61.2 (+/- 10.4), and 51.2 (+/- 8.82) Gy, respectively. The results of this study indicate that the extreme radiation sensitivity of JM109 and DH5alpha makes them unsuitable for use as surrogate microorganisms for pathogenic E. coli in the field of food irradiation research. Use of E. coli JM109 and DH5alpha, which carry mutations of the recA and gyrA genes required for efficient DNA repair and replication, is not appropriate for determination of radiation inactivation kinetics and validation of radiation processing equipment.

AN - 70335084; 18298739 AB - Listeria monocytogenes, a psychrotrophic foodborne pathogen, is a recurring postprocess contaminant on ready-to-eat meat (RTE) products, including frankfurters. Potassium lactate (PL) and sodium diacetate (SDA) are FDA-approved antimicrobials that inhibit the growth of L. monocytogenes when incorporated into the formulation of fine emulsion sausage. Flash (steam) pasteurization (FP) has been shown to reduce levels of L. monocytogenes, and its surrogate L. innocua, on frankfurter surfaces. The ability of FP to inactivate and prevent the growth of the L. monocytogenes surrogate L. innocua in a pilot plant setting was investigated. FP treatment (1.5 s, 121 degrees C) of single layers of frankfurters that were surface-inoculated with either 5, 4, or 3 log CFU/g of L. innocua immediately before FP (1.5 s, 121 degrees C) resulted in log reductions of 1.97 (+/- 0.11), 2.03 (+/- 0.10), or 2.07 (+/- 0.14), respectively. Inoculum level had no effect on the inactivation of L. innocua. Following 8 wk of refrigerated storage (4 degrees C), L. innocua levels decreased by 0.5 log in non-FP-treated frankfurter packs, while the 2 log reduction of L. innocua was maintained for FP-treated frankfurters. FP (1.5 s, 121 degrees C) had no effect on frankfurter color or texture. Because the numbers of L. monocytogenes associated with contaminations of ready-to-eat meats are typically very low, the use of FP in combination with PL and SDA has the potential to reduce the number of frankfurter recalls and foodborne illness outbreaks.

AN - 70330441; 18298720 AB - Furan, a possible carcinogen, is commonly induced by thermal processing in a wide variety of foods. The possible formation of furan from fresh-cut fruits and vegetables due to irradiation was studied. Nineteen fresh-cut fruits and vegetables were irradiated by 5 kGy gamma rays at 4 degrees C. Furan was analyzed from the irradiated samples using a number of preparation methods. The results showed that almost all tested fruits and vegetables, upon irradiation, produced nondetectable levels, or less than 1 ng/g of furan. Irradiation induced low ng/g levels of furan only in grape and pineapple. Dipping apple slices into calcium ascorbate before irradiation did not increase furan formation. The pH and the amount of simple sugars in fresh fruits and vegetables had a role in furan formation. Low levels of furan were induced by irradiation only in those fruits that had a high amount of simple sugars and low pH.

AN - 70305353; 18281587 AB - Experiments were conducted to determine the relationship between poultry chilling water volume and carcass microbiology. In the first study, the volume of water used during immersion chilling was found to have a significant effect on the counts of bacteria recovered from broiler carcass halves; however, these volumes (2.1 and 16.8 L/kg) were extreme and did not reflect commercial levels. A second study using commercial chilling volumes was conducted with 3.3 L/kg (low) or 6.7 L/kg (high) distilled water in the chiller. Prechill broiler carcasses were removed from a commercial processing line, cut into left and right halves, and one-half of each pair was individually chilled in a bag containing low or high volume of water. Bags containing halves were submersed in a secondary chill tank containing approximately 150 L of an ice-water mix (0.6 degrees C). After 45 min, halves were removed, allowed to drip for 5 min, and rinsed with 100 mL of sterile water for 1 min. Rinses were analyzed for total aerobic bacteria, Escherichia coli, Enterobacteriaceae, and Campylobacter. When the numbers of bacteria in the half-carcass rinses (HCR) were compared, counts recovered from halves chilled in a low volume of water were the same as those recovered from the halves chilled with a high volume of water (P > 0.05). Levels found in the HCR ranged from 4.0 to 4.2 log(10) cfu/mL for aerobic bacteria, 3.3 to 3.5 log(10) cfu/mL for E. coli, 3.6 to 3.8 log(10) cfu/mL for Enterobacteriaceae, and 2.4 to 2.6 log(10) cfu/mL for Campylobacter. Data were also analyzed using a paired comparison t-test, and this analysis showed that there was no difference (P > 0.05) in the numbers of aerobic bacteria, E. coli, Enterobacteriaceae, or Campylobacter recovered from paired-halves chilled in different volumes of water. The present study shows that under the conditions outlined in this experiment, doubling the amount of water during immersion chilling (3.3 vs. 6.7 L/kg) did not improve the removal of bacteria from the surfaces of chilled carcasses.

Effects on total and soluble phosphorus excretion. AN - 70302929; 18281571 AB - Dietary Ca has been reported to influence the amount of phytate excreted from broilers and affect the solubility of P in excreta. To address the effects of dietary Ca and phytate on P excretion, 12 dietary treatments were fed to broilers from 16 to 21 d of age. Treatments consisted of 3 levels of phytate P (0.10, 0.24, and 0.28%) and 4 levels of Ca (0.47, 0.70, 0.93, and 1.16%) in a randomized complete block design. Feed phytate concentrations were varied by formulating diets with 3 different soybean meals (SBM): a low-phytate SBM, a commercial SBM, and a high phytate Prolina SBM having phytate P concentrations of 0.15 to 0.51%. Fresh excreta was collected from cages during 2 separate 24-h periods; collection I commenced after the start of dietary treatments (16 to 17 d) and collection II followed a 3-d adaptation period (19 to 20 d). Ileal samples were also collected at 21 d. Excreta samples were analyzed for total P, water soluble P (WSP), and phytate P, whereas ileal samples were analyzed for total P and phytate P. Results indicated that excreta total P could be reduced by up to 63% and WSP by up to 66% with dietary inclusion of low-phytate SBM. There was a significant effect of dietary Ca on both the excreta WSP and the ratio of WSP:total P. As dietary Ca increased, the excreta WSP and WSP:total P decreased, with the effects being more pronounced following a dietary adaptation period. There was a linear relationship between the slope of the response in WSP to dietary Ca and feed phytate content for excreta from collection II (r(2) = 0.99). There was also a negative correlation between excreta phytate concentration and excreta WSP during both excreta collections. The response in WSP to dietary manipulation was important from an environmental perspective because WSP in excreta has been related to potential for off-site P losses following land application.

AN - 70289879; 18080287 AB - Clove oil, derived from the plant Syzygium aromaticum (L.) Merr. & Perry, is active against various organisms, and was prepared in a soy lecithin/detergent formulation to determine concentrations active against the root-knot nematode Meloidogyne incognita (Kofoid and White) Chitwood. In microwell assays, the mean effective clove oil concentration that reduced egg hatch by 50% (EC(50)) was 0.097% (v/v) clove oil; the EC(50) for second-stage juvenile (J2) viability was 0.145% clove oil (compared with carrier control treatments). Volatiles from 5.0% clove oil reduced nematode egg hatch in water by 30%, and decreased viability of hatched J2 by as much as 100%. Reductions were not as large with nematodes in carrier. In soil trials with J2 recovered from Baermann funnels, the EC(50) = 0.192% clove oil (compared with water controls). The results demonstrated that the tested formulation is active against M. incognita eggs and J2, that the EC(50) values for J2 in the microwell studies and the soil recovery tests were similar to each other and that direct contact with the clove oil is needed for optimal management results with this natural product.

AN - 70286075; 18268306 AB - Nitrate in water removed from fields by subsurface drain ('tile') systems is often at concentrations exceeding the 10 mg N L(-1) maximum contaminant level (MCL) set by the USEPA for drinking water and has been implicated in contributing to the hypoxia problem within the northern Gulf of Mexico. Because previous research shows that N fertilizer management alone is not sufficient for reducing NO(3) concentrations in subsurface drainage below the MCL, additional approaches are needed. In this field study, we compared the NO(3) losses in tile drainage from a conventional drainage system (CN) consisting of a free-flowing pipe installed 1.2 m below the soil surface to losses in tile drainage from two alternative drainage designs. The alternative treatments were a deep tile (DT), where the tile drain was installed 0.6 m deeper than the conventional tile depth, but with the outlet maintained at 1.2 m, and a denitrification wall (DW), where trenches excavated parallel to the tile and filled with woodchips serve as additional carbon sources to increase denitrification. Four replicate 30.5- by 42.7-m field plots were installed for each treatment in 1999 and a corn-soybean rotation initiated in 2000. Over 5 yr (2001-2005) the tile flow from the DW treatment had annual average NO(3) concentrations significantly lower than the CN treatment (8.8 vs. 22.1 mg N L(-1)). This represented an annual reduction in NO(3) mass loss of 29 kg N ha(-1) or a 55% reduction in nitrate mass lost in tile drainage for the DW treatment. The DT treatment did not consistently lower NO(3) concentrations, nor reduce the annual NO(3) mass loss in drainage. The DT treatment did exhibit lower NO(3) concentrations in tile drainage than the CN treatment during late summer when tile flow rates were minimal. There was no difference in crop yields for any of the treatments. Thus, denitrification walls are able to substantially reduce NO(3) concentrations in tile drainage for at least 5 yr.

AN - 70283913; 18268303 AB - Residual herbicides used in the production of soybean [Glycine max (L.) Merr] and corn (Zea mays L.) are often detected in surface runoff at concentrations exceeding their maximum contaminant levels (MCL) or health advisory levels (HAL). With the advent of transgenic, glyphosate-tolerant soybean and glufosinate-tolerant corn this concern might be reduced by replacing some of the residual herbicides with short half-life, strongly sorbed, contact herbicides. We applied both herbicide types to two chiseled and two no-till watersheds in a 2-yr corn-soybean rotation and at half rates to three disked watersheds in a 3-yr corn/soybean/wheat (Triticum aestivum L.)-red clover (Trifolium pratense L.) rotation and monitored herbicide losses in runoff water for four crop years. In soybean years, average glyphosate loss (0.07%) was approximately 1/7 that of metribuzin (0.48%) and about one-half that of alachlor (0.12%), residual herbicides it can replace. Maximum, annual, flow-weighted concentration of glyphosate (9.2 microg L(-1)) was well below its 700 microg L(-1) MCL and metribuzin (9.5 microg L(-1)) was well below its 200 microg L(-1) HAL, whereas alachlor (44.5 microg L(-1)) was well above its 2 microg L(-1) MCL. In corn years, average glufosinate loss (0.10%) was similar to losses of alachlor (0.07%) and linuron (0.15%), but about one-fourth that of atrazine (0.37%). Maximum, annual, flow-weighted concentration of glufosinate (no MCL) was 3.5 microg L(-1), whereas atrazine (31.5 microg L(-1)) and alachlor (9.8 microg L(-1)) substantially exceeded their MCLs of 3 and 2 microg L(-1), respectively. Regardless of tillage system, flow-weighted atrazine and alachlor concentrations exceeded their MCLs in at least one crop year. Replacing these herbicides with glyphosate and glufosinate can reduce the occurrence of dissolved herbicide concentrations in runoff exceeding drinking water standards.

Vegetated agricultural drainage ditches (VADD) have been proposed as a potential economical and environmentally efficient management practice to mitigate the effects of pesticides in irrigation and storm runoff. Three ditches were constructed in Yolo County, California for a field trial. A U-shaped vegetated ditch, a V-shaped vegetated ditch, and a V-shaped unvegetated ditch were each amended for 8 h with a mixture of diazinon, permethrin, and suspended sediment simulating an irrigation runoff event. Water, sediment, and plant samples were collected spatially and temporally and analyzed for diazinon and permethrin concentrations. Pesticide half-lives were similar between ditches and pesticides, ranging from 2.4 to 6.4 h. Differences in half-distances (distance required to reduce initial pesticide concentration by 50%) among pesticides and ditches were present, indicating importance of vegetation in mitigation. Cis-permethrin half-distances in V ditches ranged from 22 m (V-vegetated) to 50 m (V-unvegetated). Half-distances for trans-permethrin were similar, ranging from 21 m (V-vegetated) to 55 m (V-unvegetated). Diazinon half-distances demonstrated the greatest differences (55 m for V-vegetated and 158 m for V-unvegetated). Such economical and environmentally successful management practices will offer farmers, ranchers, and landowners a viable alternative to more conventional (and sometimes expensive) practices.

AN - 70283338; 18268299 AB - Soil fumigation is an important management practice for controlling soil pests and enabling successful replanting of orchards. Reducing emissions is required to minimize the possible worker and bystander risk and the contribution of fumigants to the atmosphere as volatile organic compounds that lead to the formation of ground-level ozone. A field trial was conducted in a peach orchard replant field to investigate the effects of fumigation method (shank-injection vs. subsurface drip-application treatments) and surface treatments (water applications and plastic tarps) on emissions of 1,3-dichloropropene (1,3-D) and chloropicrin (CP) from shank-injection of Telone C-35 and drip application of InLine. Treatments included control (no water or soil surface treatment); standard high-density polyethylene (HDPE) tarp, virtually impermeable film (VIF) tarp, and pre-irrigation, all over shank injection; and HDPE tarp over and irrigation with micro-sprinklers before and after the drip application. The highest 1,3-D and CP emission losses over a 2-wk monitoring period were from the control (36% 1,3-D and 30% CP) and HDPE tarp (43% 1,3-D and 17% CP) over shank injection. The pre-irrigation 4 d before fumigation and VIF tarp over shank injection had similar total emission losses (19% 1,3-D and 8-9% CP). The HDPE tarp and irrigations over subsurface drip-application treatments resulted in similar and the lowest emission losses (12-13% 1,3-D, and 2-3% CP). Lower fumigant concentrations in the soil-gas phase were observed with drip-application than in the shank-injection treatments; however, all treatments provided 100% kill to citrus nematodes in bags buried from 30 to 90 cm depth. Pre-irrigation and drip application seem to be effective to minimize emissions of 1,3-D and CP.

AN - 70273122; 18000703 AB - The genes for the patulin biosynthetic pathway are most likely arranged in a cluster, as is often the case for other mycotoxins. With this in mind, GeneWalking has been performed to identify genes both upstream and downstream of the isoepoxydon dehydrogenase (idh) gene. A gene present in Penicillium griseofulvum NRRL 2159A had high sequence homology to the isoamyl alcohol oxidase (iao) gene and was detected downstream of the idh gene and in the same orientation. By virtue of the presence of a signal peptide sequence, the newly identified gene coded for a secreted protein with an FAD-binding domain and potential for N-glycosylation. An open reading frame consisted of 1946 nucleotides, containing four putative introns and encoding a 22 amino acid signal peptide. The 571 amino acid mature protein contained nine cysteine residues and had 11 potential N-linked glycosylation sites. Searches using GenBank indicated that Aspergillus terreus, A. oryzae, A. fumigatus, and Gibberella zeae contain genes coding for a putative isoamyl alcohol oxidase. When the translated query was compared with the translated database, the highest scores were seen with A. clavatus (E value of 0.00), A. fumigatus (E value of 8e(-142)), and A. oryzae and A. terreus (each having an E value of 2e(-141)). Reverse transcription-polymerase chain reaction analysis confirmed that the iao gene was transcribed. The amplified products were sequenced for confirmation of their identities. This is the first report of an isoamyl alcohol oxidase gene in a species of the genus Penicillium.

AN - 70178110; 17680630 AB - Limited understanding of the importance of known pluripotency factors in pig embryonic stem cells (ESC) impedes the establishment and validation of porcine ESC lines. This study evaluated the expression of known mouse ESC and human ESC (hESC) pluripotency markers in in vivo inner cell mass (ICM) and in vitro-cultured undifferentiated porcine epiblast cells isolated from 8-day porcine blastocysts, primary cultures of epiblast-derived neuroprogenitor cells, and endoderm cells. The expression profile of common pluripotency markers (POU domain 5 transcript factor 1, SRY-box containing gene 2, and Nanog homeobox), species-specific markers, ESC-associated factors, and differentiation markers was evaluated. The mRNA of uncultured ICMs, cultured epiblast cells, epiblast-derived neuroprogenitor cells, and endoderm cells was amplified prior to expression analysis of candidate genes by real-time RT-PCR. ESC factors whose expression correlated best with the undifferentiated epiblast state were identified by comparative mRNA expression analysis between porcine epiblast-derived somatic cell lines, fetal fibroblasts, and adult tissues. Across tissue types Nanog homeobox exhibited ubiquitous expression, whereas POU domain 5 transcript factor 1, teratocarcinoma-derived growth factor 1, and RNA exonuclease homolog 1 transcript expression was restricted primarily to undifferentiated epiblasts. Our results suggested that expression of pluripotency markers in undifferentiated pig epiblast cells more closely resembled that observed in hESC. Expression alterations of ESC-associated factors in epiblast cells were also observed during in vitro culture. Our data demonstrate the potential use of some pluripotency factors as markers of porcine epiblast stem cells and indicate that the in vitro environment may influence the cultured epiblast's developmental state.

AN - 69441242; 18705852 AB - Fumonisins comprise a class of carcinogenic mycotoxins produced by Fusarium verticillioides during colonization of maize kernels. In previous work, we identified ZFR1, which is predicted to encode a Zn(II)2Cys6 zinc finger transcription factor required for fumonisin B(1) (FB(1)) production during growth on kernels. In this study, we characterized the role of ZFR1 in colonizing maize kernels and inducing FB(1) biosynthesis. The ZFR1 deletion strain (Deltazfr1) grew approximately 2.5-fold less than the wild-type on endosperm tissue and a variety of other carbon sources, including glucose and amylopectin. However, the Deltazfr1 strain displayed higher alpha-amylase activity and expression of genes involved in starch saccharification than the wild-type, thus indicating that the reduced growth of the Deltazfr1 strain was not due to inhibition of amylolytic enzymes. In the wild-type strain, expression of six genes encoding putative sugar transporters was significantly greater on endosperm tissue than on germ tissue, and expression of at least three of the six genes was negatively affected by disruption of ZFR1. Intriguingly, disruption of FST1 had no effect on growth, kernel colonization or kernel pH but decreased FB(1) production by approximately 82% on maize kernels. Based on these findings, we hypothesize that ZFR1 controls FB(1) biosynthesis by regulating genes involved in the perception or uptake of carbohydrates.

The site is located within a small valley on the eastern flank of Crowley's Ridge in a high risk area of the New Madrid seismic zone. In 2005 an initial geological investigation raised concerns about liquefaction potential of Quaternary age sediments. This resulted in re-examination of the proposed design. One design considered was excavation of Quaternary deposits with construction of the embankment on more competent Tertiary age sediments. This design required further testing of the foundation materials. Boreholes were not advanced much below the top of the Tertiary age Claiborne Group during the 2005 investigation. Also, the right abutment area was not completely investigated during the initial drilling program due to access problems at that time. In 2007 a supplemental geotechnical investigation was performed to address these design concerns. This investigation included 13 backhoe trenches and 13 hollow stem auger borings. In the borings, a CME continuous core barrel was advanced to 10 feet, followed by Standard Penetration Tests at 1.5 foot increments until reaching the top of Claiborne deposits. The CME core barrel was then advanced to 10 feet below the top of the Claiborne. Borings and trenches were logged using the Universal Soil Classification System. The shear strength of cohesive materials was measured using a hand-held torvane device, and 35 crumb tests were performed to check for dispersive soils. Dispersive reactions were noted in some Quaternary clay materials. A deep alluvial channel deposit composed of saturated sand was encountered in Drill Hole 701, which flowed upward into the auger during drilling. This sand deposit and others in the valley alluvium and right abutment area pose a risk of liquefaction during strong seismic events. With the possibility of removing the saturated sands to provide a dam foundation on the underlying Claiborne clay, there is also the consideration of lignite within the clay. The depth and thickness of lignite can be expected to vary considerably under the dam's footprint. In places lignite would be exposed by excavation, which is troublesome as it has shown a tendency to crumble when exposed in drill cores.

Unfortunately there are many isolated areas of this aquifer with chloride concentrations >100 mg/L in Chicot and Desha counties. Concentrations exceeding 70 mg/L are unsuitable for crops such as rice. Many high chloride areas are less than 5 miles in diameter, with no clear explanation as to their origin. A large area with total dissolved solids (TDS) concentrations exceeding 1,000 mg/L exists in southern Chicot County. Federal and State agencies are unsure how to manage this problem due to uncertainties about the source of the salinity and the potential of affected areas to spread via high groundwater pumping rates. Previous studies were researched to provide insight into these issues. Two structural features dominate this area: the Desha Basin, which stretches from Desha County into west-central Mississippi; and the Monroe Uplift. A small but strong positive magnetic anomaly underlies southern Chicot County. The center of the anomaly is about ten miles northwest of a large area with high TDS ground water. A high degree of offset along a north-south line is associated with this feature. Well logs from the northern margin of the Monroe Uplift suggest a NW-SE trending fault with approximately 100 ft displacement in upper Tertiary formations. The intersection of these two faults coincides with the area of maximum chloride and TDS concentrations in the alluvial aquifer of southern Chicot County. This would provide a mechanism for deep ground water with high TDS concentrations to migrate upwards into shallower aquifers. The Smackover Formation of Jurassic age contains briny water and is encountered at approximately 5,000 feet below sea level in southeastern Arkansas. In some areas of the MRVAA, intense pumping can create local hydraulic gradients capable of pulling saline water into the alluvium from underlying Tertiary aquifers. Upward flow from below in an area where the Jackson Formation is thin or missing could explain isolated areas of higher salinity groundwater. Thinning of the Jackson surface through channel erosion is known to have occurred in southern Chicot County. The meandering character of the band of high salinity groundwater in the alluvial aquifer also suggests such channeling.

These hydroxy fatty acids are produced in good yields from hydrolysis of sophorolipids, which are in turn derived from fermentation of fats and oils. Since the estolides are formed one unit, or ester bond, at a time, their length and sequence can be precisely controlled. The key to this control is the use of protecting groups at either the carboxylic or hydroxy end of the starting hydroxy fatty acids. Two mono-protected dimers, for example, when combined in a fragment-condensation approach, give a tetramer with no 'contamination' from estolides of other lengths. This methodology opens the way to functionalized estolides, and several variants were prepared: hybrid estolides, containing non-fatty acid moieties such as amino acids; polymerizable estolides, containing a norbornene unit; and non-linear estolides that extend from a branched core such as glycerol or pentaerythritol. With the benzoyl chloride-mediated symmetrical anhydride method, yields for individual coupling steps ranged from 75 to 93%.

Catalytically inactive, dianionic SXA (D14 super(-)E186 super(-)) has threefold lower affinity than catalytically active, monoanionic SXA (D14 super(-)E186 super(H)) for X2 and X3, whereas D14 super(-)E186 super(-) has twofold higher affinity than D14 super(-)E186 super(H) for 4-nitrophenyl-b-d-xylopyranoside (4NPX), and D14 super(-)E186 super(-) has no affinity for 4-nitrophenyl-a-l-arabinofuranoside. Anomeric isomers, a-d-xylose and b-d-xylose, have similar affinity for SXA. 4-Nitrophenol competitively inhibits SXA-catalyzed hydrolysis of 4NPX. SXA steady-state kinetic parameters account for complete progress curves of SXA-catalyzed hydrolysis reactions.

The viscoelastic properties of a newly developed biological hydrogel made from epoxidized soybean oil (ESO) were investigated. The material called HPESO is a hydrolytic product of polymerized ESO (PESO). HPESO exhibited viscoelastic solid or gel behavior above 2% (wt. %) concentration at room temperature and viscous liquid behavior at 55 °C. The thermal assembly disassembly reassembly function of the HPESO hydrogel was completely reversible. The viscoelastic properties of HPESO were dependent on concentration. Analysis of modulus and concentration dependence and stress relaxation measurement indicated that HPESO was a physical gel where the cross-linkers between the molecules were physical junctions. HPESO hydrogel also exhibited fast initial recovery of its viscoelastic properties after being subjected to mechanical shear disruption. The function and behavior of the HPESO hydrogel suggest that this biomaterial may be suitable for applications in drug delivery and scaffolds of bioengineering and tissue engineering.

Of the artificial substrates tested, BH1068(His)6 hydrolyzed nitrophenyl derivatives of beta -d-xylopyranose, alpha -l-arabinofuranose, and alpha -l-arabinopyranose. Deviation from Michaelis-Menten kinetics at higher substrate concentrations indicative of transglycosylation was observed, and k cat and K m values were measured at both low and high substrate concentrations to illuminate the relative propensities to proceed along this alternate reaction pathway. The pH maximum was 6.5, and under the conditions tested, maximal activity was at 47°C, and thermal instability occurred above 45°C. BH1068(His)6 was inactive on arabinan, hydrolyzed xylooligosaccharides, and released only xylose from oat, wheat, rye, beech, and birch arabinoxylan, and thus, can be classified as a xylosidase with respect to natural substrate specificity. The enzyme was not inhibited by up to 200 mM xylose. The oligomerization state was tetrameric under the size-exclusion chromatography conditions employed.

We investigated hydraulic redistribution (HR) by Prosopis velutina Woot. (velvet mesquite) in an upland savanna ecosystem over a two-year period. Our goal was to quantify patterns of HR by mesquite roots and assess how this affects tree water use and productivity. We used the heat ratio method to monitor bi- directional sap flow, an analog of HR, in both lateral and tap roots. Additionally, we monitored soil water content and used the eddy covariance technique to quantify ecosystem carbon dioxide and water exchange. Mesquite roots redistributed large amounts of water throughout the year, even during periods of canopy dormancy. Dormant season precipitation (November-March) was often taken up by shallow lateral roots and transferred downward in the soil profile by deeper lateral and tap roots. Such a transfer was also apparent when the trees were active and moisture from summer rainfall was plant available in the upper soil layers. As the upper soil layers dried, sap flow moving toward the canopy in the lateral roots diminished and water use from deeper soils increased via the taproots. The relationship between root sap flow and above-canopy fluxes suggested that deeper 'stored' water from HR allowed the trees to transpire more in the spring that followed a winter with significant downward redistribution. Patterns of lateral and tap root sap flow also implied that redistribution may extend the growing season of the trees after summer rains have ended and surface soils are dry, thus allowing the trees to photosynthesize through periods of seasonal drought. The large hydrologic magnitude and the ecological effects of HR we studied, along with mounting evidence of this process occurring in many other ecosystems, indicates that HR should be accounted for in many ecohydrologic modeling efforts.

Coal mining regulations require that industry perform soil sampling and submit laboratory results in order to determine premine and reclaimed soil quality. A rapid and accurate biological soil quality method, such as one-day CO sub(2) (1-day CO sub(2)) analysis, can be used to determine soil microbial activity which is related to the soils' ability to sustain nutrient cycling. Our objective in this study was to compare native and reclaimed soils from surface-mine operations in order to assess the effectiveness of the 1-day CO sub(2) method as a tool for determining biological soil quality. Soil samples were taken from sites that visually had poor and well-vegetated reclaimed areas of a surface-mine operation as well as an undisturbed native site. Chemical, physical and biological indicators were compared to 1-day CO sub(2) analysis for microbial activity. Results indicate that the biological soil quality indicators as summarized by 1-day CO sub(2) analysis are a more sensitive indicator of soil health on the reclaimed soils tested than chemical analysis alone. One-day CO sub(2) analysis can be a useful additional tool for regulators and mining companies when assessing the soils ability to sustain plant growth and evaluate reclamation success.

Remote sensing based agrometeorological models are presently most suited for estimating crop water use at both field and regional scales. Numerous ET algorithms have been developed to make use of remote sensing data acquired by sensors on airborne and satellite platforms. In this paper, a literature review was done to evaluate numerous commonly used remote sensing based algorithms for their ability to estimate regional ET accurately. The reported estimation accuracy varied from 67 to 97% for daily ET and above 94% for seasonal ET indicating that they have the potential to estimate regional ET accurately. However, there are opportunities to further improving these models for accurately estimating all energy balance components. The spatial and temporal remote sensing data from the existing set of earth observing satellite platforms are not sufficient enough to be used in the estimation of spatially distributed ET for on-farm irrigation management purposes, especially at a field scale level ( similar to 10 to 200 ha). This will be constrained further if the thermal sensors on future Landsat satellites are abandoned. However, research opportunities exist to improve the spatial and temporal resolution of ET by developing algorithms to increase the spatial resolution of reflectance and surface temperature data derived from Landsat/ASTER/MODIS images using same/other-sensor high resolution multi-spectral images.

The objective of this experiment was to show the utility of supplemental irrigation as an alternative to full-season and non-irrigation to achieve high yield and high seed composition. The effects of irrigation and cultivar differences on soybean yield and seed composition were conducted. Two cultivars (Dwight and Freedom) and three irrigation regimes (full-season irrigation, FS; reproductive stage/supplemental irrigation, RI; and non-irrigation, NI) were used. Protein percentage was higher in Dwight under FS and RI than NI. In Freedom, protein percentage was higher under NI than under FS and RI. Under NI, Freedom had higher protein percentage than Dwight, especially in 2004, but lower oil in 2003 and 2004. Cultivars showed significant differences in fatty acids. Yield in Freedom under FS and RI was not significantly different. Nitrogen fixation was substantially higher under NI conditions. The results indicate that irrigation management and cultivar selection significantly affect seed composition and yield. Protein increase in Freedom under non-irrigated conditions may benefit producers for high protein seed under dry-land conditions. Supplemental irrigation at the reproductive stage may be a possible alternative for full season irrigation for the cultivar Freedom.

Insensitivity to phenylamide fungicides was detected in isolates of P. humuli in production regions in Oregon and Idaho in 1992, and these fungicides since have been used on a limited basis. In this study, the prevalence of phenylamide insensitivity among isolates of P. humuli collected from 2005 to 2007 in the northwestern United States was quantified using a leaf disk assay with a discriminating dose (25 mu g/ml) of either metalaxyl or mefenoxam with inoculum derived from 201 systemically infected diseased shoots (basal spikes) collected from 6, 10, and 11 hop yards in Idaho, Washington, and Oregon, respectively. A subset of 47 basal spike isolates and 42 monosporic isolates collected from two yards in Idaho and nine yards in Oregon during 2006 and 2007 were assayed using a dilution series of metalaxyl to determine the effective dose that inhibited 50% of the incidence of sporulation (ED sub(50)). Insensitivity to mefenoxam was detected in 31 of 74 (41.9%) basal spikes collected from 13 hop yards. Insensitivity to the related compound metalaxyl was detected in 52 of 80 (65%) spikes collected from nine hop yards, including four hop yards in Washington. Log ED sub(50) values ranged from -2.25 to 2.67 for basal spike isolates and -2.27 to 2.98 for monosporic isolates and had a similar distribution. Log ED sub(50) values for monosporic isolates and entire basal spike isolates were significantly associated. However, the slope of the regression line was less than 1, indicating that the log ED sub(50) values obtained from entire basal spike isolates were greater than the corresponding log ED sub(50) values obtained from a monosporic isolate obtained from that spike. This research suggests that insensitivity to phenylamide fungicides is a stable phenotype in P. humuli. Management of downy mildew should rely on measures other than these fungicides in yards or regions where phenylamide insensitivity is prevalent, which is now known to include certain hop yards in Idaho, Oregon, and Washington.

We evaluated the edaphic conditions directly downstream from a stormwater retention pond to determine if sedimentation, nutrients, or elevated groundwater might have favored growth of this wetland weed. A definite signature of urban stormwater influence on reed canary grass expansion is strongly indicated by enriched nutrients (bioavailable phosphorus, nitrate-nitrogen), salt (sodium), and metals (copper and zinc), each of which was significantly elevated in the invasion area and downstream in a sedge meadow. Sodium could have dispersed clays and reduced the soil's infiltration capacity, thereby impounding water. We evaluated soil and hydrologic conditions in order to develop a conceptual model of the invasion process in Curtis Prairie. We suggest that 1) stormwater outflow from the retention pond initiated erosion; 2) reed canary grass established alongside the eroded creek and expanded vegetatively into the prairie as native plants succumbed to flooding; 3) contaminants were continuously delivered onto the floodplain, degrading soil structure and promoting aggressive growth of reed canary grass; and 4) fine-grained sediments and organic matter were transported downstream to the sedge meadow, possibly contributing to future reed canary grass expansion into this area.

None of the endophytes of these grasses were sensitive to benomyl at 3-5 ppt. The endophyte of H. brevisubulatum was sensitive only to propiconazole. The viability of the F. arundinacea endophyte (N. coenophialum) was reduced, but not completed eliminated by prochloraz, imazalil and propiconazole in the 2-3 ppt range. Aerated-steam seed treatments at 60 C for 5 min were effective in reducing viability of the perennial ryegrass endophyte (N. lolii) by 83%, although some reduction in seed germination and negative growth effects were observed. A novel disease-control method, supercritical fluid carbon dioxide extraction (SFE-CO sub(2)), for the elimination of Neotyphodiurn-endophytes in grass seeds is reported here for the first time. The endophyte N. lolii was completely controlled in seeds of L. perenne cv. Ellett by extracting the seeds at 400 atmospheres for 10 or 20 min. Only minor reductions in seed germination resulted from the SFE-CO sub(2) seed-extraction treatment and no appreciable effects on growth of seedlings or mature plants were observed. Several potential applications of these disease-control technologies for seed-borne fungal pathogens are discussed.

Definitive evidence for the skatole pathway is lacking. Deuterium-labeled substrates were employed to resolve this pathway in the acetogenic bacterium Clostridium drakei and Clostridium scatologenes and to determine if a similar pathway is used by microorganisms present in stored swine manure. Indoleacetic acid (IAA) was synthesized from tryptophan by both bacteria, and skatole was synthesized from both IAA and tryptophan. Microorganisms in swine manure produced skatole and other oxidation products from tryptophan, but IAA yielded only skatole. A catabolic mechanism for the synthesis of skatole is proposed.

Consequently, litter decomposition rates, nitrogen cycling, and carbon pools may change in agricultural systems as the result of the widespread use of Bt crops. In this study, we assessed the decomposition rates and chemical composition of commonly grown hybrids of Bt and non-Bt isolines of corn (Zea mays L.) in the field. Leaves, stalks, and cobs from two Bt corn hybrids (Pioneer 34N44 Bt and NC+ 4990 Bt) and their non-Bt isolines (Pioneer 34N43 and NC+ 4880) were analyzed for biomass fractions (soluble, hemicellulose, cellulose, and lignin) and total C and N content. Litterbags containing these residues were buried at a depth of 10 cm in a Holdrege silt loam (fine-silty, mixed, mesic Typic Argiustolls) soil and recovered 5, 11, 17, and 23 months after placement in the field. There were no differences in the rates of decomposition and mass of C remaining over time between the Bt and non-Bt corn residues. Plant parts differed in decomposition rates where leaves > stalks > cobs. There were differences in total C, total N, biomass fractions, and C:N ratios between initial Bt and non-Bt corn residues, and between companies (NC+ and Pioneer), however, these differences did not result in differences in their rates of decomposition or mass of C remaining over time. For each plant part, there were no differences in lignin content between the Bt and non-Bt residues. These data suggest that the Bt and non-Bt corn hybrids used in this study should not cause differences in carbon sequestration when their residues decompose under similar environmental conditions.

Cows were stratified by age and breed and assigned randomly to receive intramammary treatment (n = 99) at weaning or as untreated controls (n = 97). Quarter milk samples were collected at weaning and at 8 to 14 d after calving. Milk samples were analyzed for somatic cell counts (SCC) and mastitis-causing bacteria. Dry cow treatment decreased (P = 0.005) the number of cows infected after calving. Treatment decreased (P = 0.04) the number of cows that developed new infections and reduced (P = 0.03) the number of quarters with mastitis-causing bacteria after calving that were infected at weaning. Somatic cell counts after calving were greatest (P = 0.008) for cows infected with Staphylococcus aureus. Treatment did not alter (P = 0.19) SCC of quarters after calving that were infected with S. aureus at weaning but reduced (P = 0.002) SCC after calving of quarters that were infected with coagulase-negative staphylococci at weaning. Body weight of calves during early lactation was increased (P = 0.006) if cows with intramammary infection were treated at weaning. Treatment of noninfected cows at weaning increased (P = 0.008) adjusted 205-d weaning weights of calves after the subsequent lactation when compared with untreated noninfected cows. We conclude that treatment of beef cows at weaning with intramammary antibiotics decreased intramammary infections after calving, improved udder health during the subsequent lactation, and increased BW gain of the calves.

This disease is caused by the bacterium Xylella fastidiosa and the pathogen is vectored by xylem-feeding sharpshooters and spittlebugs. Currently, there are no effective management techniques that prevent trees from becoming infected. Within affected orchards throughout California's Central Valley, disease incidence and the risk of tree-to-tree spread appears to be low. Consequently, the decision to remove or keep infected trees depends on lost productivity. We compared yield and vitality between infected and uninfected almond for cvs. Sonora and Nonpareil. Sonora was examined at three sites over 3 years and Nonpareil was examined at one site over 2 years. Yields of ALS-affected trees were significantly lower for both cultivars, although yield losses of Sonora were proportionally greater than those of Nonpareil. Yields of infected trees did not decline incrementally over years; rather, they fluctuated similarly to those of uninfected trees. In addition, no infected trees died during the course of the study. These results are in direct contrast to previous anecdotal reports which suggest that yields of infected trees incrementally decline and infected trees eventually die. A simple economic model was developed to determine conditions under which rouging infected trees would increase returns. Based on the model, orchard age, yield loss due to infection, and the value of a maximally producing almond tree should be considered when deciding to remove ALS-affected trees.

Foliar and basal cover at the time of apeak standing crop were visually estimated using modified Daubenmire cover categories, and forage production by species was harvested from areas that had been excluded from large herbivores. Responses of forage production to precipitation, but not foliar and basal cover, were similar for the three semi-arid ecosystems. Total forage production was more responsive (75-159%) than basal (8-35%) or foliar (2-29%) cover to increasing precipitation. Absolute (1016kg^; ha@@u-1@) and relative (159%) increases in total forage production from 2004 to 2005 were greatest for the shortgrass steppe. Forage production increases were largely attributable to greater production by C3 perennial graminoids in each ecosystem; increases in basal and foliar cover for this plant functional group were observed in shortgrass steppe and sagebrush grassland, but not in northern mixed-grass prairie. Fine-scale inputs of species and plant functional group responses to precipitation will further the accuracy of forage prediction models in predicting both total biomass production and relative proportions of plant biomass.

During our analysis period (1650-1900), we reconstructed fires from 9245 fire scars on 576 trees (mostly ponderosa pine, Pinus ponderosa P. & C. Lawson) at 21 sites and compared them to existing tree-ring reconstructions of climate (temperature and the Palmer Drought Severity Index [PDSI]) and large-scale climate patterns that affect modern spring climate in this region (El Nino-Southern Oscillation [ENSO] and the Pacific Decadal Oscillation [PDO]). We identified 32 regional-fire years as those with five or more sites with fire. Fires were remarkably widespread during such years, including one year (1748) in which fires were recorded at 10 sites across what are today seven national forests plus one site on state land. During regional-fire years, spring-summers were significantly warm and summers were significantly warm-dry whereas the opposite conditions prevailed during the 99 years when no fires were recorded at any of our sites (no-fire years). Climate in prior years was not significantly associated with regional- or no-fire years. Years when fire was recorded at only a few of our sites occurred under a broad range of climate conditions, highlighting the fact that the regional climate drivers of fire are most evident when fires are synchronized across a large area. No-fire years tended to occur during La Nina years, which tend to have anomalously deep snowpacks in this region. However, ENSO was not a significant driver of regional-fire years, consistent with the greater influence of La Nina than El Nino conditions on the spring climate of this region. PDO was not a significant driver of past fire, despite being a strong driver of modern spring climate and modern regional-fire years in the northern Rockies.

These interactions have adversely affected the grapefruit industry and have led a need to develop a process to remove the FCs from grapefruit juice (GFJ) in a manner that retains much of the original juice sensory attributes. In our experiments, grapefruit juice was incubated with Aspergillus niger, and the compositional changes in hydroxycinnamates, flavonoid glycosides, and the FCs were monitored. Many of the FCs and 7-geranyloxycoumarin were efficiently taken up by the fungal tissue, whereas no uptake occurred with the polar hydroxycinnamates, flavonoid glycosides, and a few of the polar FCs. This biosorption was also observed with autoclaved A. niger, indicating that the uptake of non-polar FCs by the fungal hyphae was due to adsorption rather than metabolism. The binding of the FCs to autoclaved fungus was complete within 4 h, and the level of binding was proportional to the amount of autoclaved fungal hyphae used. This removal of the FCs from GFJ led to a reduced inhibition of CYP 3A4 activity in in vitro assays by both GFJ and GFJ extracts.

Under all three scenarios, Alpine/Subalpine Forest cover declined, and increases in the productivity of evergreen hardwoods led to the displacement of Evergreen Conifer Forest by Mixed Evergreen Forest. Grassland expanded, largely at the expense of Woodland and Shrubland, even under the cooler and less dry climate scenario where increased woody plant production was offset by increased wildfire. Increases in net primary productivity under the cooler and less dry scenario contributed to a simulated carbon sink of about 321 teragrams for California by the end of the century. Declines in net primary productivity under the two warmer and drier scenarios contributed to a net loss of carbon ranging from about 76 to 129 teragrams. Total annual area burned in California increased under all three scenarios, ranging from 9-15% above the historical norm by the end of the century. Annual biomass consumption by fire by the end of the century was about 18% greater than the historical norm under the more productive cooler and less dry scenario. Under the warmer and drier scenarios, simulated biomass consumption was initially greater, but then at, or below, the historical norm by the end of the century.

Integrated/crop livestock experiments that involve adequate treatments and replications, as perceived by both crop and animal scientists, require large numbers of hectares, many animals, considerable labor to conduct the research, substantial financial resources, and a commitment by Federal and State Research Agencies to fund such long-term research projects. To be truly integrated, crop/livestock research must be multidisciplinary, involving scientists of diverse training and experience with expertise to address various aspects of the research problem, and scientists must function as a cohesive unit or team. The prevailing attitude that all experimental data must be statistically analyzed to be of any value is also a detriment to integrated research. Statistical analyses of these projects may be quite challenging and require new or unusual approaches. Related to the prevailing need for statistical analysis is also the need for scientists to publish senior authored publications for career advancement. Conducting integrated research may not facilitate scientists' publishing the number and quality of publications required for them to meet these criteria. A further obstacle to integrated research alluded to above, involves the many experimental design compromises that must be made by cooperating scientists. Crop and soil scientists for example, use many treatments and replications with small plots, while animal scientists, by necessity, have experiments that involve relatively large numbers of hectares and animal numbers with relatively few treatments and replications. It is therefore extremely difficult to initiate such projects given these inherent differences in crop versus livestock research protocol, as well as to design effective experiments that will provide publishable data. Making compromises on the many factors relevant to integrated crop/livestock research while designing experiments that will provide solutions to pertinent producer problems as well as useful data that can be statistically analyzed and published is, therefore, extremely difficult.

Our objectives were to (1) test a modified pole graduated with 1.27-cm (0.5-inch) bands for estimating standing herbage based on linear regression of visual obstruction readings (VORs) on standing herbage, (2) validate the derived regression, (3) provide sample size estimates, and (4) develop guidelines for monitoring mountain grasslands. Each transect had 20 visual obstruction stations spaced 10 meters apart with 4 visual obstruction readings at each station. At 4 stations, vegetation within a 0.25-m super(2) area was clipped at ground level. VORs and clipped standing herbage were averaged by transect for analysis. Visual obstruction reliably predicted average standing herbage (dry weights) for mountain meadows (r super(2) = 0.81, sx = 382 kg times ha super(-1)). Standing herbage ranged from 387 kg times ha super(-1) to 3930 kg times ha super(-1), with a mean of 1742 kg times ha super(-1). A validation data set of 13 transects sampled across the range of variation in standing crop showed that 85% of transects fell within the 90% prediction limits. We recommend a minimum of 4 transects for monitoring key areas or small areas up to 259 ha (640 acres) when managers need to consider differences in VOR bands and address multiple objectives. Cluster analyses (ISODATA) applied to the pole readings resulted in 4 visual obstruction categories: short, short-intermediate, tall-intermediate, and tall. This tool provides a simple, reliable, and cost-effective (time-saving) alternative to clipping vegetation and obtaining dry weights for monitoring.

Many studies have compared community and ecosystem characteristics on prairie dog colonies to grasslands without prairie dogs, but little is known about landscape-scale patterns of disturbance that prairie dog colony complexes may impose on grasslands over long time periods. We examined spatiotemporal dynamics in two prairie dog colony complexes in southeastern Colorado (Comanche) and northcentral Montana (Phillips County) that have been strongly influenced by plague, and compared them to a complex unaffected by plague in northwestern Nebraska (Oglala). Both plague-affected complexes exhibited substantial spatiotemporal variability in the area occupied during a decade, in contrast to the stability of colonies in the Oglala complex. However, the plague-affected complexes differed in spatial patterns of colony movement. Colonies in the Comanche complex in shortgrass steppe shifted locations over a decade. Only 10% of the area occupied in 1995 was still occupied by prairie dogs in 2006. In 2005 and 2006 respectively, 74 and 83% of the total area of the Comanche complex occurred in locations that were not occupied in 1995, and only 1% of the complex was occupied continuously over a decade. In contrast, prairie dogs in the Phillips County complex in mixed-grass prairie and sagebrush steppe primarily recolonized previously occupied areas after plague-induced colony declines. In Phillips County, 62% of the area occupied in 1993 was also occupied by prairie dogs in 2004, and 12% of the complex was occupied continuously over a decade. Our results indicate that plague accelerates spatiotemporal movement of prairie dog colonies, and have significant implications for landscape-scale effects of prairie dog disturbance on grassland composition and productivity. These findings highlight the need to combine landscape-scale measures of habitat suitability with long-term measures of colony locations to understand the role of plague-affected prairie dogs as a grassland disturbance process.

We used a random-walk model to identify three qualitative responses to edges: no edge effect (the null model), reflecting edges and absorbing edges. Interestingly, no edge effect meant that abundance was lower at edges than in the center of patches, and reflecting edges have similar abundance at edges and centers. We then characterized several insect species' response within maize plots to patch edges and patch size, using a simple, quick, qualitative experiment. Coleomegilla maculata and Trichogramma spp. were the only organisms that responded to patch size and edges as patch theory and the null edge model would predict. Ostrinia nubilalis larvae and possibly Rhopalosiphum maidis and eggs of Chrysopa spp. responded to patch size and edges as predicted by an attracting edge model. Estimation of predation rates suggested that the spatial distribution of these species might be determined by predators. Edge effects or the lack thereof relative to patch size may be rapidly determined for arthropod species, which could lead to understanding the mechanism(s) underlying these effects. This information may be useful in reaction diffusion models through a scaling-up approach to predict population structure of species among patches in a landscape.

Volumetric soil water content ( psi sub(v)) in relation to irrigation, plant uptake, and yield in potato hills and replicated plots was studied to evaluate four water management options. Measurements of psi sub(v) using a hammer driven probe were used to derive a psi sub(v) index representing the relative psi sub(v) status of replicated plots positioned along a hill slope. Time series for psi sub(v) were determined using time domain reflectometry (TDR) probes at 5 and 15cm depths at the center, shoulder, and furrow locations in potato hills. Sap flow was determined using flow collars in replicated field plots for four treatments: un-irrigated, sprinkler, surface drip, and sub-surface drip irrigation (40cm depth). Irrigated yields were high/low as the psi sub(v) index was low/high suggesting psi sub(v) excess was a production problem in the wetter portions of the study area. The diurnal pattern of sap flow was reflected in the psi sub(v) fluctuation it induces at hill locations with appreciable uptake. Hill locations with higher plant uptake were drier as was the case for the 5cm (dry) depth relative to the 15cm (wet) depth and for locations in the hill (dry) relative to the furrow (wet). The surface drip system had the lowest water use requirement because it delivers water directly to the hill locations where uptake is greatest. The sub-surface drip system wetted the hill gradually (1-2 days). Measurement of the psi sub(v) index prior to experimental establishment could improve future experimental design for treatment comparisons.

A major late blight resistance gene, called RB, previously was identified in the wild potato species Solanum bulbocastanum through map-based cloning. The full-length gene coding sequence, including the open reading frame and promoter, has been integrated into cultivated potato (5. tuberosum) using Agrobacterium-mediated transformation. RB-containing transgenic plants were challenged with P. infestans under optimal late blight conditions in greenhouse experiments. All transgenic lines containing RB exhibited strong foliar resistance. Field-grown transgenic tubers also were tested for resistance to P. infestans. In contrast to the foliar resistance phenotype, RB-containing tubers did not exhibit increased resistance. Two years of field trials were used to ascertain whether the presence of RB had any effect on tuber yield. We were unable to detect any significant effect on tuber size or yield after addition of the resistance gene to several S. tuberosum cultivars.

Typically, the carbohydrate is derivatized to form acid-stable methyl ethers, hydrolyzed, peracetylated, and analyzed by gas chromatography-mass spectrometry. The position of glycosidic linkages in the starting carbohydrate are apparent from the mass spectra as determined by the location of acetyl residues. The completeness of permethylation is dependent upon the choice of base catalyst and is readily confirmed by matrix-assisted laser desorption/ionization time-of-flight mass spectrometry mass spectrometry. For the permethylation of beta -cyclodextrin, Hakomori dimsyl base is shown to be superior to the NaOH--dimethyl sulfoxide system, and the use of the latter resulted in selective under-methylation of the 3-hydroxy groups. These techniques are highly applicable to residual carbohydrates from biofuel processes.

We investigated the orientation responses of dispersing neonates to herbivore damage in cowpea seedlings, specifically examining whether neonate behaviors were affected by inceptin, the primary elicitor of FAW-induced defenses in cowpea leaves. We focused on responses to damage caused by conspecific first instars, as might occur during the dispersal of siblings from an egg mass. Inceptin contents of damaging first instar FAW were controlled through their diets, with leaf-fed FAW producing inceptins in their oral secretions, and root-fed or starved FAW lacking these elicitors. In a bioassay designed to evaluate neonate dispersal off a host plant, a higher percentage of neonates remained on herbivore-induced or inceptin-treated plants than on undamaged plants, mechanically damaged plants, freshly damaged plants, or on plants damaged by FAW lacking inceptins. Further investigations of neonate responses to plant odors with a four-arm olfactometer demonstrated that neonate attraction to odors from 4-h old FAW damage was strongly dependent on previous diet of the damaging larvae. Neonates were attracted to odors from 4-h old FAW damage over odors from undamaged plants or fresh FAW damage, provided that the damaging larvae had previously ingested leaf material. In a direct comparison of odors from induced plants, plants damaged by leaf-fed FAW were as attractive as plants treated with synthetic inceptin. GC-MS analysis confirmed that (E)-4,8-dimethyl-1,3,7-nonatriene (DMNT) was the major volatile induced by FAW herbivory. While both DMNT and undamaged plant odors were more attractive than air, neonates preferred DMNT-supplemented plant odors. These results suggest that neonate FAW exploit herbivore-induced plant volatiles as host plant location and recognition cues.

Potential dedicated feedstock species vary in degrees of recalcitrance to ethanol processing. The standard dilute acid hydrolysis pretreatment followed by simultaneous sacharification and fermentation (SSF) was performed on leaf and stem material from three grasses: giant reed (Arundo donax L.), napiergrass (Pennisetum purpureum Schumach.), and bermudagrass (Cynodon spp). In a separate study, napiergrass, and bermudagrass whole samples were pretreated with esterase and cellulose before fermentation. Conversion via SSF was greatest with two bermudagrass cultivars (140 and 122 mg g of biomass) followed by leaves of two napiergrass genotypes (107 and 97 mg g) and two giant reed clones (109 and 85 mg g). Variability existed among bermudagrass cultivars for conversion to ethanol after esterase and cellulase treatments, with Tifton 85 (289 mg g) and Coastcross II (284 mg g) being superior to Coastal (247 mg g) and Tifton 44 (245 mg g). Results suggest that ethanol yields vary significantly for feedstocks by species and within species and that genetic breeding for improved feedstocks should be possible.

The polymyxin-resistant mutant Brucella abortus AJ100 was characterized by comparing its susceptibility to the polycationic antibiotic polymyxin B, defensins, and lactoferricin, and its colonization and clearance in the mouse model to the parent strain RB51. MIC (minimum inhibitory concentration) values determined by Etest for AJ100 and RB51 were 1.5 and 0.25 mu g/ml, respectively. Though AJ100 is less susceptible to polymyxin B than RB51, it was more susceptible than its parent strain to the cationic defensins melittin, magainin 2, and cecropin P1. In the mouse model, initial colonization of the spleen was lower for AJ100 than RB51, and the rate of clearance from the spleen was faster for AJ100 than RB51. However, initial colonization and clearance rates of AJ100 from the liver were indistinguishable from those of RB51. This study suggests that the susceptibility profile of Brucella to polycationic defensins rather than polymyxin B may be indicative of differential survival in the spleen and liver in the mouse and is indicative of spleen and liver residential macrophages' differing ability to inactivate Brucella.

The disease is transmitted primarily through systemically infected nursery stock. This creates problems for nurseries wishing to export plants to Europe because of quarantine restrictions. Currently, field inspections for symptoms are used to certify plants free of X. fragariae, but visual inspection is not useful for detecting plants infected systemically. To detect systemic infections, polymerase chain reaction (PCR) is the desired tool because of its sensitivity, specificity, and ease of use. In this study, we developed three sets of real-time PCR primers and probes and determined optimal reaction conditions for use of these primers for the detection of the bacterium X. fragariae in strawberry crown tissue. Real time detection proved to be both more sensitive and specific than standard PCR. Moreover, the detection of X. fragariae in crown tissue extract was possible with real-time PCR but not with standard PCR which is a significant improvement over standard PCR. The information on sensitivity and specificity of the primer sets was used to evaluate the performance of these primers with receiver operating characteristic (ROC) curve analysis under different tolerances. The results of this analysis can be used to provide guidance on threshold selection to manage disease below unacceptable levels. The results of this research may be useful to regulators and inspectors who must certify that plants meet European and Mediterranean Plant Protection Organization standards.

They were tested for virulence on seedlings of differential oat lines in the greenhouse. In all, 171 races were found among the 357 isolates from the winter oat region of the United States, whereas 212 races were found among 323 isolates from the spring oat region. The crown rust population derived from winter oat in the southern United States was distinct from the spring oat population in the upper Midwest, although there was no virulence unique to either population. Virulence to Pc48 and Pc52 increased significantly in both regions during 2001 to 2005. Virulence to Pc59 increased and virulence to Pc53 decreased in the winter oat region during the same period. Many of the virulence associations previously reported in the U.S. oat crown rust population in the early 1990s also were found in both regions in this survey. Associations between virulence to the Pc genes were predominately positive in both regions; however, both positive and negative associations occurred more frequently in the winter oat region. Much of the virulence diversity in the oat crown rust population in the United States can be related to the deployment of resistance genes in commercial oat cultivars and virulence associations existing in the oat crown rust population. The mean virulence of the U.S. populations of crown rust continued to increase from 2001 to 2005. Genes for crown rust resistance derived from A. sterilis appear to be rapidly defeated, as has happened to Pc genes from A. sativa.

Specimens were collected on 27 July 2004 and sent to the USDA-ARS at Ft. Detrick, MD for identification of disease and pathogen. Pure culture of a bacterium was obtained on potato dextrose agar, and hyperplasia and hypertrophy developed on carrot disks and tomato stems after wound inoculation with a needle contaminated by the agar culture. The same bacterium was reisolated from the galls on DK, thus fulfilling Koch's postulates. Pathogenicity tests involving needle inoculations of stems and petioles resulted in gall formation on Acroptilon repens, Cartha-mus tinctorius, Centaurea solstitialis, C. maculosa, C. cyanus, Crupina vulgaris, Helianthus annuus, and Rubus armeniacus. In biochemical tests typically used for identification of Agrobacterium species (3), the DK strain grew on DIM agar but not on 2% NaCl medium, produced acid from erythritol but not from melezitose, converted malonic acid to base, and turned litmus milk alkaline. These results are characteristic of Agrobacterium rhizogenes (= Biovar 2), except for the litmus milk reaction. Using 16S rRNA cluster analysis by unweighted pair group method with arithmetic mean (UPGMA, 500 replicates) and basic local alignment search tool (BLAST), the DK strain clustered most closely with A. rubi (GenBank Accession Nos. D12787 and AM181759). The DK strain differed from A. larrymoorei (GenBank Accession No. Z30542), A. tumefa-ciens (GenBank Accession No. AJ389896), A. rhizogenes (GenBank Accession No. AB247607), and A. vitis (GenBank Accession No. AB247599) on the basis of 16S rRNA sequence cluster analysis. The DK strain differed from A. rubi on the basis of differential reactions with erythritol, litmus milk, and 2% NaCl medium (2,4); and the 16S rRNA sequence of the DK strain differed from that of A. rubi by 11 bp (99.2% similarity). Comparisons also were made between the DK strain and two strains (83A and 135A) of A. tumefaciens (= Biovar 1), described from New Mexico on A. repens (1), a plant species in the same tribe and subtribe of the As-teraceae as DK. Host range reported for the two A. repens strains after artificial greenhouse inoculations was similar to that of the DK strain and it included diffuse knapweed (1). However, 16S sequencing, which confirmed identification of both A. repens strains as A. tumefaciens, showed they differed from the DK strain. The DK strain belongs in the genus Agrobacterium, but it could not be assigned to any known species on the basis of data from phenotypic or 16S sequence comparisons. To our knowledge, this is the first report of crown gall on diffuse knapweed in the field. This strain has been deposited into the International Collection of Phytopathogenic Bacteria at Fort Detrick (Accession No. 60099), and the 16S rRNA sequence has been deposited into the GenBank database (Accession No. EF687663).

Recent studies indicate that cloud bases may have risen over the past 30 years, resulting in less frequent forest cloud immersion, and that further increases in cloud base height are likely in the event of continued climate warming. To assess the impact of this trend on the regeneration of high altitude spruce-fir forests and the migration of plant communities, in particular the encroachment of spruce-fir forests and Rhododendron catawbiense Michx. islands into adjacent grass bald communities, we investigated effects of cloud immersion on photosynthetic parameters of seedlings of Abies fraseri and R. catawbiense in a grass bald site and A. fraseri in a forest understory. Although photosynthetic photon flux was 4.2 to 19.4-fold greater during clear conditions, cloud immersion had no effect on photosynthesis in A. fraseri at either site, whereas it reduced photosynthesis of R. catawbiense by about 40%. However, cloud immersion increased mean leaf fluorescence by 7.1 to 12.8% in both species at both sites. Cloud immersion increased mean relative humidity from 65 to 96%, reduced transpiration by 95% and reduced mean leaf-to-air temperature difference from 6.6 to 0.5 degree C.

Previous screens for genetic resistance in tobacco have been limited. The objective of this study was to evaluate 97 genotypes composing several classes of tobacco and related Nicotiana spp. for seedling resistance to stem rot and target spot. Significant differences in disease incidence initially were observed among the genotypes for both stem rot and target spot; however, resistance to target spot was not observed when disease pressure was high. Partial resistance to stem rot was observed in several genotypes in repeated tests. These accessions may be useful as a source of resistance to R. solani in future breeding efforts.

To investigate the mechanisms behind this increased disease, soils from tilled or direct-seeded fields were inoculated with Rhizoctonia spp. at population densities from 0.8 to 250 propagules per gram and planted with barley (Hordeum vulgare). The incidence and severity of disease did not differ between soils with different tillage histories. Both R. solani AG-8 and R. oryzae stunted plants at high inoculum densities, with the latter causing pre-emergence damping-off. High inoculum densities of both species stimulated early production of crown roots in barley seedlings. Intact soil cores from these same tilled and direct-seeded fields were used to evaluate the growth of Rhizoctonia spp. from colonized oat seeds. Growth of R. oryzae was not affected by previous tillage history. However, R. solani AG-8 grew more rapidly through soil from a long-term direct-seeded field compared to tilled soils. The differential response between these two experiments (mixed, homogenized soil versus intact soil) suggests that soil structure plays a major role in the proliferation of R. solani AG-8 through soils with different tillage histories.

Andrus & Moore, was tested at different inoculum concentrations alone and in combination with, prior to or following treatment with different rates of glyphosate (N-[phosphonomethyl]glycine) (Roundup Ultra) for the control of hemp sesbania (Sesbania exaltata [Raf.] Rydb. ex A.W. Hill) in Roundup Ready soybean field plots. Colletotrichum truncatum and glyphosate were applied in all pair-wise combinations of 0, 1.25, 2.5, 5.0, and 10.0106sporesmL-1 (i.e. 3.125, 6.25, 12.5, and 251011sporesha-1), and 0.15, 0.30, 0.60, and 1.2kgha-1, respectively. Weed control and disease incidence were enhanced at the two lowest fungal and herbicidal rates when the fungal spores were applied after glyphosate treatment. The application of the fungus in combination with or prior to glyphosate application at 0.30kgha-1 resulted in reduced disease incidence and weed control regardless of the inoculum's concentration. At the highest glyphosate rates, the weeds were controlled by the herbicide alone. These results suggest that it might be possible to utilize additive or synergistic herbicide and pathogen interactions to enhance hemp sesbania control.

Ditmar: Fr., was tested alone and in combination with a glyphosate (N-[phosphonomethyl]glycine) product for controlling natural infestations of the invasive vines, redvine (Brunnichia ovata [Walt.] Shinners) and trumpetcreeper (Campsis radicans [L.] Seem. ex Bureau). After 12days, redvine and trumpetcreeper were controlled by 88% and 90%, respectively, through a synergistic interaction between the fungus and the herbicide, glyphosate. The disease symptomatology was characterized by rapid necrosis of the leaf and stem tissues, with mortality occurring within 72h. Neither glyphosate alone, nor M.verrucaria alone, controlled these weeds at commercially acceptable levels (.80%). No visual disease or herbicide damage occurred to the soybean in the treated test plots 12days after planting. These results suggest that some formulations of glyphosate, mixed with M.verrucaria, can effectively control redvine and trumpetcreeper.

Most commercial RNA kits are not suitable for starchy materials. Traditional RNA extraction procedures, in addition to being laborious and time consuming, leave hazardous organic wastes that result in expensive disposal costs. Interestingly, the numerous commercial DNA isolation kits now available often include directions for eliminating co-isolated RNA. This indicated an approach to obtain the generally unwanted RNA by-product by treating the total extraction product to intentionally retain RNA. A method was developed by which a two-step DNase procedure was applied to the product of the Cartagen Food DNA extraction kit that eliminated the DNA but left the co-extracted RNA. This modified procedure was compared with several other commercial and standard methods that are promoted as being able to work under high polysaccharide conditions. Successful extraction was determined by the production and amplification of cDNA by RT-PCR of actin. Extraction was successful from milled rice, as well as from cornmeal and wheat flour.

In this study we tested the efficacy of 5 species/strains of EPN in an Oxisol under greenhouse conditions. The nematodes were applied at 100 infective juveniles per cm2 to 19-L pots containing a high clay-content Oxisol (69% clay) and 3 seedlings of Litchi chinensis. All treatments significantly reduced the mean proportion of D. abbreviatus larvae surviving (ranging from 0 to 36%) compared to survival in untreated controls (ranging from 80 to 86%). This suggests that EPNs might be suitable to play a role in integrated pest management strategies against D. abbreviatus in tropical soils with high clay content.

Whereas poultry litter (PL) is a traditionally inexpensive and effective fertilizer to improve soil quality and agricultural productivity, overapplication to soils has raised concerns because excess nutrients in runoff could accelerate the eutrophication of fresh bodies of water. A long-term field experiment of land application of PL to soils used for pasture growth has been maintained for nearly two decades in the Sand Mountain region of north Alabama, USA. In this work, several soil parameters impacted by the long-term applied litter were characterized. The findings clearly support previous general observations that long-term applied litter on pasture soils altered soil properties and macrocation levels. Unlike other studies, however, the effects of applied litter at multiple rates and years were examined, thus revealing the dynamic impacts on soil properties. Hay yields increased with the increase of years of PL application, regardless of the applied rate. This observation was consistent with previous observations that the labile phosphorus (P) portion in these soils increases with application years whereas total P increases with the cumulative applied PL amounts. Poultry litter application did not markedly affect soil electric conductivity, bulk density, or sodium (Na) or potassium (K) levels, especially at the soil surface (0-20cm). Soil pH, carbon (C), C/nitrogen (N) ratio, calcium (Ca), and magnesium (Mg) were profoundly affected at all three soil depths (0-20, 20-40, and 40-60cm). Most soil parameters analyzed in this study reached peak values with 10-15 years of applied litter. This observation suggests that there was a turning point of impact for applied litter around 10 years: prior to that the soil macrocations were altered positively as a result of accumulative functions. Continuous litter application may negatively alter a soil's capacity to retain macrocations, leading to less impact observed in this study. In other words, pasture soils with more than 10 years of applied litter would have higher potential for leaching and runoff. Our observation suggested that best management practices for land application of PL should take into consideration the different effects of PL application history.

The objective was to determine the effect of flow through discontinuous soil- pipes on ephemeral gully erosion. Experiments were conducted on 150 cm long by 100 cm wide soil beds with an artificial soil-pipe at the upper end that extended 50 cm into the soil immediately above a water-restricting horizon. The combination of rainfall with pipe flow produced extensive (63 kg) soil losses by mass wasting. The mode of mass wasting appeared to be sudden, cataclysmic pop-out failures. Total soil loss by sheet erosion with rainfall and pipe flow combined (13.6 kg) was four times higher than by rainfall alone (3.4 kg). Under rainfall with pipe flow, soil loss by mass wasting was nearly 20 times higher than sheet erosion from rainfall alone. Soil conservation practices that treat surface runoff process alone may be ineffective if subsurface flow is contributing.

8157361 AB - Four Salmonella bacteriophages that had been originally isolated from swine manure lagoons were characterized and compared to each other and to well-known Salmonella phages P22 and Felix 01. Host ranges of the lagoon phages were similar to each other in spot tests on reference strains of Salmonella, but differed slightly from each other on a panel of Salmonella lagoon strains. In single-step growth at 35 degree C the lagoon phages had latent periods of 15 to 20 min and burst sizes from 100 to 230. The lagoon phages and P22 were purified by cesium chloride (CsCl) gradient centrifugation and used to produce specific antisera and DNA. The lagoon phages were indistinguishable from each other but distinct from P22 and Felix 01 in immunodiffusion and infectivity neutralization tests and in restriction digest analysis.

In addition, a growing list of genomic resources have been developed or are currently under development including: cDNA libraries, BAC libraries, EST sequences, BAC end sequences, a physical map, genetic markers, a linkage map and, most importantly, the complete genome sequence. To maximize the utility of Brachypodium as a model grass it is necessary to develop an efficient Agrobacterium-mediated transformation system. In this report we describe the identification of a transformable inbred diploid line, Bd21-3, and the development of a transformation method with transformation efficiencies as high as 41% of co-cultivated calluses producing transgenic plants. Conducting the co-cultivation step under desiccating conditions produced the greatest improvement in transformation efficiency.

Microorganisms isolated from 287 roots fell into the following groups: A (41% of strains), B (29%), C (17%), D (11%), E (2%), and F (1%). Groups A, B, C, and F were composed of bacteria while groups D and E were yeasts. Subgroup A1 (80% of group A strains) included Leuconostoc mesenteroides subsp. dextranicum strains and subgroup A2 (20%) contained Lactobacillus strains. Group B was dominated by subgroup B1 (92% of strains), which included Gluconobacter strains. When only one organism was isolated from rotted roots, strains from subgroup A1 were isolated most frequently. Group C was composed of enteric bacteria. Strain B322 of L. mesenteroides subsp. dextranicum caused the most severe rot on root slices and produced symptoms similar to those in harvested roots. Results suggest that L. mesenteroides subsp. dextranicum is among the first bacterial species to enter sugar beet roots, closely following fungal infections or entering directly through openings such as growth cracks. The bacterial rot leads to yield loss in the field but likely also leads to storage and factory-processing problems.

This disease has been difficult to control because of the lack of an effective vaccine. To address this need, we adapted a specialized transduction system originally developed for M. tuberculosis and modified it to improve the efficiency of allelic exchange in order to generate site-directed mutations in preselected M. avium subsp. paratuberculosis genes. With our novel optimized method, the allelic exchange frequency was 78 to 100% and the transduction frequency was 1.1 x 10 super(-7) to 2.9 x 10 super(-7). Three genes were selected for mutagenesis: pknG and relA, which are genes that are known to be important virulence factors in M. tuberculosis and M. bovis, and lsr2, a gene regulating lipid biosynthesis and antibiotic resistance. Mutants were successfully generated with a virulent strain of M. avium subsp. paratuberculosis (M. avium subsp. paratuberculosis K10) and with a recombinant K10 strain expressing the green fluorescent protein gene, gfp. The improved efficiency of disruption of selected genes in M. avium subsp. paratuberculosis should accelerate development of additional mutants for vaccine testing and functional studies.

The incidence of aflatoxin varies with environmental conditions, genotype, and location. An expanded understanding of the interaction of the plant, fungus, and weather conditions is needed to further elucidate the field infection process of maize by A. flavus and subsequent aflatoxin contamination. One of the problems in evaluating maize hybrids for resistance to kernel infection and aflatoxin contamination is identifying a time period and environmental conditions that are most advantageous. Three maize genotypes (Pioneer Brand 3223, Mo18W x Mp313E, and Mp313E x Mp420) were evaluated from 1998 to 2002 in response to A. flavus inoculation and aflatoxin contamination and weather conditions favorable for aflatoxin contamination were identified. The highest aflatoxin levels were observed in 1998 and 2000 (1186 and 901 ng g super(-1); P < 0.0001); while the lowest levels were detected in 1999 (39 ng g super(-1)). Pioneer 3223 had significantly higher levels (1198 ng g super(-1)) than Mp313E x Mp420 (205 ng g super(-1)), and Mo18W x Mp313E (161 ng g super(-1); P < 0.0001). The hybrids had six weather-related variables in common that were positively correlated with aflatoxin accumulation. Four of these occurred during 65-85 days after planting and were temperature-related. These results suggest that regardless of the hybrid's maturity or physiological development, the time from 65 to 85 days after planting may be indicative of a period of stress which leads to greater aflatoxin accumulation at harvest.

Xanthomonas campestris pv. vesicatoria strains carrying AvrRxv induce a hypersensitive response (HR) in the tomato cultivar Hawaii 7998. Using a yeast two-hybrid screen, we identified a 14-3-3 protein from tomato that interacts with AvrRxv called AvrRxv interactor 1 (ARI1). The interaction was confirmed in vitro with affinity chromatography. Using mutagenesis, we identified a 14-3-3-binding domain in AvrRxv and demonstrated that a mutant in that domain showed concomitant loss of interaction with ARI1 and HR-inducing activity in tomato. These results demonstrate that the AvrRxv bacterial effector recruits 14-3-3 proteins for its function within host cells. AvrRxv homologues YopP and YopJ from Yersinia do not have AvrRxv-specific HR-inducing activity when delivered into tomato host cells by Agrobacterium. Although YopP itself cannot induce HR, its C-terminal domain containing the catalytic residues can replace that of AvrRxv in an AvrRxv-YopP chimera for HR-inducing activity. Phylogenetic analysis indicates that the sequences encoding the C-termini of family members are evolving independently from those encoding the N-termini. Our results support a model in which there are three functional domains in proteins of the family: translocation, interaction, and catalytic.

Boat damage has long been recognized for its negative impacts on shallow-water seagrass beds, with those along the Florida coast particularly vulnerable in the face of a large human population possessing a large number of boats. Boat scars to seagrass beds recover slowly, resulting in new damage that often outpaces recovery of existing damage. We examined the rate of accumulation of total area composed of boat scars from 1994 to 2005 at Lignumvitae Key Submerged Land Managed Area, an area containing approximately 3400 ha of seagrass beds. We found the total area of damage increased from 1994 to 1997 by an average of 27.1 ha/y and from 1997 to 2005 by an average of 10.8 ha/y. This most recent rate of damage increase represents an additional $1,523,819 annual loss in habitat value using cost figures based on costs from restoration attempts permitted by the Environmental Protection Agency. Severe groundings investigated by law enforcement officers showed increasing trends over time in the average amount and severity of damage. The size of the boat inflicting the damage was more closely related to the severity of damage than to the amount of damage. The most immediate and practical measures for preventing damage include increasing signage to warn boaters to avoid seagrass beds and increasing law enforcement staff. Signage is a relatively low-cost, long-term investment that becomes cost-effective even if only 0.03 ha of seagrass bed damage is averted over the life of the signs. Each patrol staff member added becomes cost-effective even if only 0.42 ha of damage is averted annually. Holding the total area of damage constant for 1 year (new damage = recovery) would represent a benefit-cost ratio of 25.71 if accomplished with only one additional law enforcement officer.

It is of major concern to regulatory agencies because it has a wide host range and high reproductive potential. A weather-based mapping tool, NAPPFAST, was used to predict potential establishment of S. dorsalis in North America. The analysis was based on a degree-day model and cold temperature survival of S. dorsalis. The results demonstrated that S. dorsalis could potentially produce up to 18 generations and was likely to survive in the southern and western coastal plains of the United States. It is concluded that S. dorsalis is likely to be a serious economic pest in the southern United States. Additional maps and information are available at the web site (http://www.nappfast.org).

The United States channel catfish (Ictalurus punctatus) aquaculture industry is severely impacted by columnaris disease. The majority of the F. columnare isolates recovered from diseased channel catfish belonged to either genomovars I or II. The objective of the present study was to determine if differences existed in the ability of these genomovars to induce mortality in channel catfish. Single strand conformation polymorphism analysis (SSCP) was used to ascribe the isolates used in this study to the appropriate genomovar. Immersion challenge experiments (15 min immersion exposure to 5 X 105 to 1 X 106 CFU/mL) were carried out to assess virulence of genomovar I and II isolates to channel catfish. The results demonstrated that genomovar II (n = 4) isolates were significantly (P < 0.05) more virulent to channel catfish fry (92-100% mortality) than genomovar I (n = 3) isolates (0-46% mortality). In vivo adhesion of the genetically characterized F. columnare also correlated (r2 = 0.73) to increased mortality in the challenged fry. In fingerling channel catfish, significantly higher mortality (P < 0.05) resulted with genomovar II isolates ALM-05-182 and ALG-00-530 as compared to all the genomovar I isolates (n = 3). Mortality of genomovar II isolate BGFS-27 with similar to genomovar II isolate (ALG-00-530) and two genomovar I isolates (ALM-05-53 and 140). The results suggest that although both genomovars are present in the aquatic environment, genomovar II appears to be more pathogenic for channel catfish.

The objective of this study was to identify loci contributing to SLB resistance in two recombinant inbred line populations and to compare these to SLB resistance loci in other populations. The two populations used were derived from crosses between maize inbred lines H99 and B73 (HB population-142 lines) and between B73 and B52 (BB population-186 lines). They were evaluated for SLB resistance and for days from planting to anthesis (DTA) in 2005 and 2006. Two replications arranged as randomized complete blocks were assessed in each year for each population. Entry mean heritabilities for disease resistance were high for both populations (0.876 and 0.761, respectively). Quantitative trait loci (QTL) for SLB resistance were identified in bins 3.04 (two QTL), 6.01, and 8.05 in the HB population and in bin 2.07 in the BB population. No overlap of DTA and SLB resistance QTL was observed, nor was there any phenotypic correlation between the traits. A comparison of the results of all published SLB resistance QTL studies suggested that bins 3.04 and 6.01 are 'hotspots' for SLB resistance QTL.

Salmonella Agona isolates exhibited increased resistance to amoxicillin/clavulanic acid, ampicillin, cefoxitin, ceftiofur, cephalothin, and chloramphenicol, and a single isolate was resistant to ceftriaxone. Multiple drug resistance (MDR; resistance greater than or equal to 2 antimicrobials) was exhibited in 57% (n = 282/499) of the Salmonella Agona isolates and 22% (n = 111/499) of these Salmonella Agona isolates were resistant to five or more antimicrobials. PFGE patterns of 482 Salmonella Agona slaughter samples resulted in 165 unique patterns. Cluster analysis indicated that isolates indistinguishable by PFGE appeared to group according to antimicrobial resistance profiles. These data suggest that Salmonella Agona is increasing in prevalence in U.S. cattle presented for slaughter and should be further monitored.

The isolate produced a 5,362-Da bacteriocin (enterocin) that inhibits the growth of Salmonella enterica serovar Enteritidis, S. enterica serovar Choleraesuis, S. enterica serovar Typhimurium, S. enterica serovar Gallinarum, Escherichia coli O157:H7, Yersinia enterocolitica, Citrobacter freundii, Klebsiella pneumoniae, Shigella dysenteriae, Pseudomonas aeruginosa, Proteus mirabilis, Morganella morganii, Staphylococcus aureus, Staphylococcus epidermidis, Listeria monocytogenes, Campylobacter jejuni, and 20 other Campylobacter species isolates. The enterocin, E-760, was isolated and purified by cation-exchange and hydrophobic-interaction chromatographies. The proteinaceous nature of purified enterocin E-760 was demonstrated upon treatment with various proteolytic enzymes. Specifically, the antimicrobial peptide was found to be sensitive to beta-chymotrypsin, proteinase K, and papain, while it was resistant to lysozyme and lipase. The enterocin demonstrated thermostability by retaining activity after 5 min at 100 degree C and was stable at pH values between 5.0 and 8.7. However, activity was lost below pH 3.0 and above pH 9.5. Administration of enterocin E-760-treated feed significantly (P < 0.05) reduced the colonization of young broiler chicks experimentally challenged and colonized with two strains of C. jejuni by more than 8 log sub(10) CFU. Enterocin E-760 also significantly (P < 0.05) reduced the colonization of naturally acquired Campylobacter species in market age broiler chickens when administered in treated feed 4 days prior to analysis.

This study focused on the impact of three different antimicrobial regimes (low-level continuous, pulse, and no antimicrobial) for two antimicrobials (chlortetracycline and tylosin) on the presence of Salmonella spp. and on the prevalence of antimicrobial resistance of both Salmonella spp. and nonspecific Escherichia coli in fecal samples from feeder swine. The prevalence of fecal samples positive for Salmonella spp. significantly decreased between the samples taken at feeder placement compared to samples taken when the animals were close to market weight. Differences in resistance of Salmonella spp. did not appear to be influenced by dosing treatment including the control. Analysis of antimicrobial resistance examining both susceptibility and resistance, as well as MIC outcomes, demonstrated that only resistance to cephalothin increased in E. coli under the pulse chlortetracycline treatment. These results suggest that the dosing regimes examined in this study did not lead to an increase in either the prevalence of Salmonella spp. or the prevalence of antimicrobial resistance in isolates of Salmonella spp. or E. coli.

We tabulated occurrences and estimated diameters of 3483 General Land Office bearing trees across 19 survey townships along an upland soil texture and organic matter gradient in north Mississippi. We then contrasted this presettlement composition and structure with that of 2998 trees in sampling plots within present-day mature (>100 years old) upland forests contained within the survey townships. Presettlement upland communities appeared to consist of non-successional communities, in which the most abundant trees were shade-intolerant, fire-tolerant trees (e.g., Quercus marilandica [blackjack oak]) in both large and small size classes across the entire soil gradient. These fire-prone pre-settlement assemblages differed greatly from present-day mature uplands, which were transitional assemblages of upland and floodplain trees, with mesophytic floodplain species (both early and late-successional) dominating the smaller size classes.

However, these surrogate approaches are not applicable to all situations. In this article we discuss how the nature of the ecological system, the objectives and scale of management, and the level of available knowledge influence the decision about using a surrogate approach. We use species-area relations to define a 'surrogate zone' in which the approach may be most effective. Using the Interior Columbia Basin of the northwestern United States as an example, we outline 10 steps that may enhance the effectiveness of surrogate approaches. Using a surrogate approach necessarily entails a trade-off between management tailored to individual species and less precise practices that may apply to a broader array of species. Ultimately, the use of a surrogate approach depends on the level of uncertainty that is acceptable in conducting management or conservation activities-in other words, 'How good is good enough?'

Manipulations of fish movement onto high marsh surfaces revealed similar growth rates and production among fish that were (1) restricted to pools, (2) had access to known areas of marsh surface, or (3) had free access to the entire marsh. Smaller scale manipulations with marked fish revealed that males with access to the marsh surface accumulated significantly more biomass, often exhibited higher growth rates, and had a 1.6x greater production rate than males restricted to pools. Female production was only slightly higher for fish that could access the marsh compared to fish restricted to pools. While both pools and marsh surface appeared to support fish production, habitat partitioning also existed between sexes of mummichogs; males may rely more on the marsh surface for food while females rely more on pools. Growth and production of mummichogs in pools on the high marsh surface was lower than values reported from more southern, low marsh dominated systems. This was attributed to differences in (1) abiotic factors of salt marsh pools (this study) and tidal creeks and channels (other studies), (2) climate, and (3) tidal inundation and access time to the marsh surface. Fish production on the surface of Gulf of Maine high marsh ecosystems was equivalent to production in adjacent tidal creeks and channels. Thus, the high marsh surface proved to be an important habitat for supporting fish production in this region.

Above-ground habitat characteristics of overwintering sites and randomly selected points within the study area were assessed. All individuals entered overwintering between 29 August and 19 September with a mean estimated entrance date of 7 September. Arrival of the first subzero nighttime air temperatures occurred shortly thereafter on 16 September. No lizard left its normal area of use to overwinter, and there was no tendency to aggregate. Lizards did not necessarily overwinter on warmer south-facing slopes; the proportion of overwintering sites oriented southward (0.62) was not different from random. Most lizards (75%) selected overwintering sites in the banks of washes that had relatively steep slopes and at specific locations where substrate was relatively bare and penetrable. Overwintering sites also tended to have a greater coverage of Yucca glauca (0.02%) than the general study area (0.01%). Analyses of historical soil temperature data from the CPER revealed that lizards would have to overwinter at a subsoil depth of about 1 m to avoid freezing temperatures. Banks that contain suitable hibernation sites that are located within an individual's normal area of use may be the habitat feature most important to successful overwintering.

We hypothesized that crested wheatgrass defoliation greater than 60% during the spring would provide maximum medusahead (Taeniatherum caput-medsae [L.] Nevski subsp. asperum [Simk.] Melderis; taxonomy from US Department of Agriculture) density and biomass. Eighteen treatments (six defoliation levels, three seasons of defoliation) were applied to 2-m2 plots in a randomized complete block design on two sites with varying clay content. Blocks were replicated five times at each site. Plants were clipped in 2004 and 2005. Crested wheatgrass was hand clipped to defoliation levels of 0%, 20%, 40%, 60%, 80%, and 100% in the spring, summer, or fall. Density of crested wheatgrass and medusahead was sampled in June 2005 and 2006, but their biomass was harvested only in 2006. Data were analyzed with least square means analysis of variance. Over the two seasons, site had much more of an impact on medusahead invasion than either defoliation intensity or timing of defoliation. The results support previous suggestions that clayey soils favor medusahead and that perennial grasses with high biomass can resist this invasive species. On the clayey site where medusahead did persist, fall defoliation of crested wheatgrass reduced the density of this invasive species by 50% or more compared to spring defoliation. Given the developmental pattern of medusahead, the goal of any management program should be to maximize resource use by the desirable species during April to late July.

This furry yellow and black bee has been confused with the closely related C. lanosa Cresson, a native bee restricted to northern Florida and the American Southwest and adjacent Mexico. Female C. nitida are smaller than those of both C. lanosa and C. errans Fox, a furry brown-colored native Centris which is sympatric with C. nitida in southern Florida. The 3 Centris bees now occurring in Florida are readily separated by their distinctive facial markings. Female C. nitida have a vertical black line in the middle of the clypeus. Centris nitida is a polylectic, oil-collecting bee observed to visit flowers of 28 species in 10 plant families, including 8 oil reward flower species in the Malpighiaceae, and 10 species of buzz pollinated flowers in the Fabaceae and Solanaceae in Florida.

This phenomenon has been called temporal stability, time stability, temporal persistence, or rank stability in spatial patterns of soil water contents. Temporal stability is of considerable interest in terms of facilitating upscaling of observed soil water contents to obtain average values across the observation area, improving soil water monitoring strategies, and correcting the monitoring results for missing data. The objective of this work was to contribute to the existing knowledge base on temporal stability in soil water patterns using frequent multi-depth measurements with Multisensor Capacitance Probes (MCPs) installed in a coarse-texture soil under multi-year corn production. Water contents at 10, 30, 50, and 80 cm depths were measured every 10 min for 20 months of continuous observation from May 2001 to December 2002. The MCPs revealed temporal stability in soil water content patterns. Temporal stability was found to increase with depth. The statistical hypothesis could not be rejected (P < 0.0001) that data collected each 10 min, each 2 h, each day, and each week had the same temporal stability. The locations that were best for estimating the average water contents were different for different depths. The best three locations for the whole observation period were the same as the best locations for a month of observations in about 60% of the cases. Temporal stability for a specific location and depth could serve as a good predictor of the utility of this location for estimating the area-average soil water content for that depth. Temporal stability could be efficiently used to correct area-average water contents for missing data. Soil water contents can be upscaled and efficiently monitored using the temporal stability of soil water content patterns.

AN - 70283708; 18166238 AB - Caffeic acid (3,4-dihydroxycinnamic acid, 12 mM) added to a fat-based growth medium reduces >95% of aflatoxin production by Aspergillus flavus NRRL 3357, without affecting fungal growth. Microarray analysis of caffeic acid-treated A. flavus indicated expression of almost all genes in the aflatoxin biosynthetic cluster were down-regulated, ranging from a log2 ratio of caffeic acid treated and untreated of -1.12 (medium) to -3.13 (high). The only exceptions were genes norB and the aflatoxin pathway regulator-gene, aflJ, which showed low expression levels in both treated and control fungi. The secondary metabolism regulator-gene, laeA, also showed little change in expression levels between the fungal cohorts. Alternatively, expression of genes in metabolic pathways (i.e., amino acid biosynthesis, metabolism of aromatic compounds, etc.) increased (log2 ratio >1.5). The most notable up-regulation of A. flavus expression occurred in four genes that are orthologs of the Saccharomyces cerevisiae AHP1 family of genes. These genes encode alkyl hydroperoxide reductases that detoxify organic peroxides. These increases ranged from a log2 ratio of 1.08 to 2.65 (moderate to high), according to real-time quantitative reverse transcription-PCR (qRT-PCR) assays. Based on responses of S. cerevisiae gene deletion mutants involved in oxidative stress response, caffeic, chlorogenic, gallic and ascorbic acids were potent antioxidants under oxidative stress induced by organic peroxides, tert-butyl and cumene hydroperoxides. Differential hypersensitivity to these peroxides and hydrogen peroxide occurred among different mutants in addition to their ability to recover with different antioxidants. These findings suggest antioxidants may trigger induction of genes encoding alkyl hydroperoxide reductases in A. flavus. The possibilities that induction of these genes protects the fungus from oxidizing agents (e.g., lipoperoxides, reactive oxygen species, etc.) produced during host-plant infection and this detoxification attenuates upstream signals triggering aflatoxigenesis are discussed.

AN - 70335826; 18301739 AB - In the U.S., tomatoes have become the most implicated vehicle for produce-associated Salmonellosis with 12 outbreaks since 1998. Although unconfirmed, trace backs suggest pre-harvest contamination with Salmonella enterica. Routes of tomato crop contamination by S. enterica in the absence of direct artificial inoculation have not been investigated. This work examined the role of contaminated soil, the potential for crop debris to act as inoculum from one crop to the next, and any interaction between the seedbourne plant pathogen Xanthomonas campestris pv. vesicatoria and S. enterica on tomato plants. Our results show S. enterica can survive for up to six weeks in fallow soil with the ability to contaminate tomato plants. We found S. enterica can contaminate a subsequent crop via crop debris; however a fallow period between crop incorporation and subsequent seeding can affect contamination patterns. Throughout these studies, populations of S. enterica declined over time and there was no bacterial growth in either the phyllosphere or rhizoplane. The presence of X. campestris pv. vesicatoria on co-colonized tomato plants had no effect on the incidence of S. enterica tomato phyllosphere contamination. However, growth of S. enterica in the tomato phyllosphere occurred on co-colonized plants in the absence of plant disease. S. enterica contaminated soil can lead to contamination of the tomato phyllosphere. A six week lag period between soil contamination and tomato seeding did not deter subsequent crop contamination. In the absence of plant disease, presence of the bacterial plant pathogen, X. campestris pv. vesicatoria was beneficial to S. enterica allowing multiplication of the human pathogen population. Any event leading to soil contamination with S. enterica could pose a public health risk with subsequent tomato production, especially in areas prone to bacterial spot disease.

Experiments were carried out under chemically unfavorable conditions for colloid attachment to both solid-water interfaces (SWI) and air-water interfaces (AWI) using negatively charged and hydrophilic colloids and modifying the solution chemistry with a bicarbonate buffer to pH 10. Interaction energy calculations and complementary batch experiments were conducted and demonstrated that partitioning of colloids to the SWI and AWI was insignificant across the range of the ionic strengths considered. The breakthrough curve and final deposition profile were measured in each experiment indicating colloid retention was highly dependent on the suspension ionic strength, water content, and sand grain size. In contrast to conventional filtration theory, most colloids were found deposited close to the column inlet, and hyper-exponential deposition profiles were observed. A mathematical model, accounting for time- and depth-dependent straining, produced a reasonably good fit for both the breakthrough curves and final deposition profiles. Experimental and modeling results suggest that straining - the retention of colloids in low velocity regions of porous media such as grain junctions - was the primary mechanism of colloid retention under both saturated and unsaturated conditions. The extent of stagnant regions of flow within the pore structure is enhanced with decreasing water content, leading to a greater amount of retention. Ionic strength also contributes to straining, because the number of colloids that are held in the secondary energy minimum increases with ionic strength. These weakly associated colloids are prone to be translated to stagnation regions formed at grain-grain junctions, the solid-water-air triple point, and dead-end pores and then becoming trapped.

AN - 70418615; 18351108 AB - Endocrine disrupting chemicals (EDCs) impair living organisms by interfering with hormonal processes controlling cellular development Reduction of EDCs in water by an environmentally benign method is an important green chemistry goal. One EDC, 17alpha-ethinylestradiol (EE2), the active ingredient in the birth control pill, is excreted by humans to produce a major source of artificial environmental estrogenicity, which is incompletely removed by currenttechnologies used by municipal wastewater treatment plants (MWTPs). Natural estrogens found in animal waste from concentrated animal feeding operations (CAFOs) can also increase estrogenic activity of surface waters. An iron-tetraamidomacrocyclic ligand (Fe-TAML) activator in trace concentrations activates hydrogen peroxide and was shown to rapidly degrade these natural and synthetic reproductive hormones found in agricultural and municipal effluent streams. On the basis of liquid chromatography tandem mass spectrometry, apparent half-lives for 17 alpha- and 17 beta-estradiol, estriol, estrone, and EE2 in the presence of Fe-TAML and hydrogen peroxide were approximately 5 min and included a concomitant loss of estrogenic activity as established by E-Screen assay.

AN - 70300111; 18279085 AB - To evaluate the feasibility for Rift Valley fever virus (RVFV) to enter the continental United States by various routes as well as to identify states in which domestic and wild ruminant and human populations would be most vulnerable to exposure to RVFV. Pathways analysis. Animals, commodities, and humans transported from RVFV-endemic countries to the continental United States between 2000 and 2005. Initially, agent, host, and environmental factors important in the epidemiologic aspects of RVFV were used to develop a list of potential pathways for release of RVFV into the continental United States. Next, the feasibility of each pathway was evaluated by use of data contained in governmental and public domain sources. Finally, entry points into the continental United States for each feasible pathway were used to identify the domestic and wild ruminant and human populations at risk for exposure to RVFV. Feasible pathways for entry of RVFV into the continental United States were importation of RVFV-infected animals, entry of RVFV-infected people, mechanical transport of RVFV-infected insect vectors, and smuggling of live virus. Domestic ruminant livestock, ruminant wildlife, and people in 14 states (Alabama, California, Florida, Georgia, Maine, Maryland, Massachusetts, Minnesota, New Jersey, New York, Pennsylvania, South Carolina, Texas, and Virginia) appeared to be most vulnerable to exposure to RVFV. Pathways analysis can provide the requisite information needed to construct an effective targeted surveillance plan for RVFV to enable rapid detection and response by animal health and public health officials.

Because liquid water absorbs in the shortwave infrared, the normalized difference infrared index (NDII), calculated from Landsat 5 Thematic Mapper band 4 (0.76-0.90 mu m wavelength) and band 5 (1.55-1.65 mu m wavelength), can be used to determine canopy equivalent water thickness (EWT), which is defined as the water volume per leaf area times the leaf area index (LAI). Alternatively, average canopy EWT can be determined using a landcover classification, because different vegetation types have different average LAI at the peak of the growing season. The primary contribution of this study for the Soil Moisture Experiment 2004 was to sample vegetation for the Arizona and Sonora study areas. Vegetation was sampled to achieve a range of canopy EWT; LAI was measured using a plant canopy analyzer and digital hemispherical (fisheye) photographs. NDII was linearly related to measured canopy EWT with an R super(2) of 0.601. Landcover of the Arizona, USA, and Sonora, Mexico, study areas were classified with an overall accuracy of 70% using a rule-based decision tree using three dates of Landsat 5 Thematic Mapper imagery and digital elevation data. There was a large range of NDII per landcover class at the peak of the growing season, indicating that canopy EWT should be estimated directly using NDII or other shortwave-infrared vegetation indices. However, landcover classifications will still be necessary to obtain total vegetation water content from canopy EWT and other data, because considerable liquid water is contained in the non-foliar components of vegetation.

Semi-arid landscapes present a particular challenge to satellite remote sensing validation using traditional techniques because of the high spatial variability and potentially rapid rates of temporal change in moisture conditions. In this study, temporal stability analysis and spatial sampling techniques are used to investigate the representativeness of ground observations at satellite scale soil moisture in a semi-arid watershed for a long study period (March 1, 2002 to September 13, 2005). The watershed utilized, the Walnut Gulch Experimental Watershed, has a dense network of 19 soil moisture sensors, distributed over a 150 km super(2) study region. In conjunction with this monitoring network, intensive gravimetric soil moisture sampling conducted as part of the Soil Moisture Experiment in 2004 (SMEX04), contributed to the calibration of the network for large-scale estimation during the North American Monsoon System (NAMS). The sensor network is shown to be an excellent estimator of the watershed average with an accuracy of approximately 0.01 m super(3)/m super(3) soil moisture. However, temporal stability analysis indicated that while much of the network is stable, the soil moisture spatial pattern, as represented by mean relative difference, is not replicated by the network mean relative difference pattern. Rather, the network is composed of statistical samples. Geophysical aspects of the watershed, including topography and soil type are also examined for their influence on the soil moisture variability and stability. Soil type, as characterized by bulk density, clay and sand content, was responsible for nearly 50% of the temporal stability. Topographic effects were less important in defining representativeness and stability.

In this paper, a two-source energy balance model developed to use thermal and visible /near-infrared remotely sensed data is applied to Landsat imagery collected during the 2004 Soil Moisture Experiment (SMEX04) conducted in southern Arizona. Using a two dimensional flux-footprint algorithm, modeled surface fluxes are compared to tower measurements at three locations in the SMEX04 study area: two upland sites, and one riparian site. The effect of pixel resolution on evaluating the performance of the land surface model and interpreting spatial variations of land surface fluxes over these heterogeneous areas is evaluated. Three Landsat scenes were examined, one representing the dry season and the other two representing the relatively wet monsoon season. The model was run at three resolution scales: namely the Landsat visible/near-infrared band resolution (30 m), the Landsat 5 thermal band resolution (120 m), and 960 m, which is nominally the MODIS thermal resolution at near-nadir. Comparisons between modeled and measured fluxes at the three tower sites showed good agreement at the 30 m and 120 m resolutions - pixel scales at which the source area influencing the tower measurement (~100 m) is reasonably resolved. At 960 m, the agreement is relatively poor, especially for the latent heat flux, due to sub-pixel heterogeneity in land surface conditions at scales exceeding the tower footprint. Therefore in this particular landscape, thermal data at 1-km resolution are not useful in assessing the intrinsic accuracy of the land-surface model in comparison with tower fluxes. Furthermore, important spatial patterns in the landscape are lost at this resolution. Currently, there are no definite plans supporting high resolution thermal data with regular global coverage below ~700 m after Landsat 5 and ASTER fail. This will be a serious problem for the application and validation of thermal-based land-surface models over heterogeneous landscapes.

One of the objectives of the Soil Moisture Experiments 2004 (SMEX04) was to address some aspects of this problem, specifically variability introduced by vegetation, topography and convective precipitation. Other goals included supporting the development of soil moisture data sets that would contribute to understanding the role of the land surface in the concurrent North American Monsoon System. SMEX04 was conducted over two regions: Arizona - semi-arid climate with sparse vegetation and moderate topography, and Sonora (Mexico) - moderate vegetation with strong topographic gradients. The Polarimetric Scanning Radiometer (PSR/CX) was flown on a Naval Research Lab P-3B aircraft as part of SMEX04 (10 dates of coverage over Arizona and 11 over Sonora). Radio Frequency Interference (RFI) was observed in both PSR and satellite-based (AMSR-E) observations at 6.92 GHz over Arizona, but no detectable RFI was observed over the Sonora domain. The PSR estimated soil moisture was in agreement with the ground-based estimates of soil moisture over both domains. The estimated error over the Sonora domain (SEE=0.021 cm super(3)/cm super(3)) was higher than over the Arizona domain (SEE=0.014 cm super(3)/cm super(3)). These results show the possibility of estimating soil moisture in areas of moderate and heterogeneous vegetation and high topographic variability.

To provide a framework for answering these questions, two cyclophilin cDNA of channel catfish, Ictalurus punctatus, were identified, sequenced and characterized. The complete nucleotide sequences of cyclophilin A and cyclophilin B cDNA consisted of 1170 and 996 bases, respectively. Analyses of the sequences revealed each had one open reading frame potentially encoding 164 amino acids with calculated molecular mass of 17,450Da and 216 amino acids with calculated molecular mass of 23,852Da for cyclophilin A and cyclophilin B, respectively. The degrees of conservation of channel catfish cyclophilin A and cyclophilin B amino acid sequences to counterparts of other species ranged from 74 to 84% and 80 to 92%, respectively. Both cyclophilin A and cyclophilin B transcripts were constitutively expressed in all tissues of channel catfish examined in this study.

We measured net exchange of water vapor fluxes in a 63-year-old mature hardwood (MHW) stand, a 60-year-old mature red pine (MRP) stand, a 3-year-old young hardwood (YHW) stand, a 17-year-old intermediate hardwood (IHW) stand, a young red pine (YRP age 8) stand, an intermediate red pine (IRP age 21) stand, and two pine barren ecosystems burned 12 years (PB1) and 2 years (PB2) ago. Field data suggested that there were no significant differences in growing season (June-September) ET/precipitation ratio among all ecosystems in 2002. However, PB2 had significantly lower ET/precipitation than those of other ecosystems in 2003. The ratios were much higher for all ecosystems, up to 0.90 for IHW, during the peak summer months (June-July). PB2 was the lowest (0.64) during that period. Stand leaf area index alone did not explain ecosystem ET at the landscape scale. Seasonal ET values measured by the eddy covariance method were significantly lower than those simulated with a process-based hydrologic model, MIKE SHE. Our integration approach combined with field measurements and simulation modeling proved to be useful in providing a full picture of the effects of forest cover type change on landscape scale water balance at multiple temporal scales. The ET procedure used in the MIKE SHE model needs improvement to fully account for the effects of vapor pressure deficit on tree transpiration. Seasonal distributions of ET coincided with precipitation in the growing season, when fluxes estimated by both field and models were the highest. The simulation model suggests that removal of conifer forests in the study region may reduce ET immediately by 113-30mm /year or about 20%, but our field data suggests that ET can recover within 8-25 years from re-growth of hardwood forests.

The objectives of this study are to delineate potential current and future oak decline areas using species composition and age structure data in combination with ecological land types, and to investigate how relatively frequent simulated fires and fire suppression affect the dynamics of oak decline. We parameterized LANDIS, a spatially explicit forest succession and disturbance model, for areas in the Boston Mountains of Arkansas, USA. Land type distribution and initial species/age class were parameterized into LANDIS using existing forest data. Tree species were parameterized as five functional groups including white oak (Quercus alba L., Quercus stellata Wangenh., Quercus muehlenbergii Engelm.), red oak (Qurecus rubra L., Quercus marilandica Muenchh., Quercus falcata Michx., Quercus coccinea Muenchh.), black oak (Quercus velutina Lam.), shortleaf pine (Pinus echinata Mill), and maple (Acer rubrum L., Acer saccharum Marsh.) groups. Two fire regimes were also parameterized: current fire regime with a fire return interval of 300 years and a historic fire regime with an overall average fire return interval of 50 years. The 150-year simulation suggests that white oak and shortleaf pine abundance would increase under the historic fire regime and that the red oak group abundance increases under the current fire regime. The black oak group also shows a strong increasing trend under the current fire regime, and only the maple group remains relatively unchanged under both scenarios. At present, 45% of the sites in the study area are classified as potential oak decline sites (sites where red and black oak are >70 years old). After 150 simulation years, 30% of the sites are classified as potential oak decline sites under the current fire regime whereas 20% of the sites are potential oak decline sites under the historic fire regime. This analysis delineates potential oak decline sites and establishes risk ratings for these areas. This is a further step toward precision management and planning.

A first order inactivation kinetic model is described by the D value and the z value. These kinetic data are critical in the design, operation and regulation of thermal pasteurization. D and z values of Salmonella enteritidis strain 13076 and Escherichia coli K12 in liquid whole egg and liquid egg white were determined over the temperature range from 52 to 60 [deg]C. In liquid whole egg, D sub(54, D) sub(5)6, D sub(58 and D) sub(6)0 values of S. enteritidis strain 13076 were 5.70, 0.82, 0.27 and 0.17 min, respectively, and D sub(54, D) sub(5)6, D sub(58 and D) sub(6)0 values of E. coli K12 were 9.10, 1.41, 0.67 and 0.22 min, respectively. In liquid egg white, D sub(52, D) sub(5)4, D sub(56 and D) sub(5)8 values of S. enteritidis strain 13076 were 6.12, 1.51, 0.42 and 0.19 min, respectively, and D sub(52, D) sub(5)4, D sub(56 and D) sub(5)8 values of E. coli K12 were 10.18, 1.82, 0.78 and 0.28 min, respectively. The z values for S. enteritidis strain 13076 and E. coli K12 ranged from 3.95 to 4.03 [deg]C. The results showed that D values of S. enteritidis strain 13076 and E. coli K12 in liquid whole egg were higher than those in liquid egg white. E. coli K12 exhibited similar kinetic behavior, but higher thermal resistance than S. enteritidis strain 13076 in both liquid egg white and liquid whole egg. This study demonstrated that non-pathogenic E. coli K12 may serve as a surrogate for pathogenic S. enteritidis in liquid egg in the validation of a thermal pasteurization.

AN - 70413333; 18348790 AB - One of the possible adverse effects of transgenic insecticidal crops is the unintended decline in the abundance of nontarget arthropods. Field trials designed to evaluate potential nontarget effects can be more complex than expected because decisions to conduct field trials and the selection of taxa to include are not always guided by the results of laboratory tests. Also, recent studies emphasize the potential for indirect effects (adverse impacts to nontarget arthropods without feeding directly on plant tissues), which are difficult to predict because of interactions among nontarget arthropods, target pests, and transgenic crops. As a consequence, field studies may attempt to monitor expansive lists of arthropod taxa, making the design of such broad studies more difficult and reducing the likelihood of detecting any negative effects that might be present. To improve the taxonomic focus and statistical rigor of future studies, existing field data and corresponding power analysis may provide useful guidance. Analysis of control data from several nontarget field trials using repeated-measures designs suggests that while detection of small effects may require considerable increases in replication, there are taxa from different ecological roles that are sampled effectively using standard methods. The use of statistical power to guide selection of taxa for nontarget trials reflects scientists' inability to predict the complex interactions among arthropod taxa, particularly when laboratory trials fail to provide guidance on which groups are more likely to be affected. However, scientists still may exercise judgment, including taxa that are not included in or supported by power analyses.

AN - 70385155; 18330133 AB - Susceptibility to spiromesifen, a tetronic acid derivative, was determined for three imidacloprid-resistant strains and 12 geographically discrete natural populations of Bemisia tabaci (Gennadius) (=Bemisia argentifolii Bellows & Perring) (Hemiptera: Aleyrodidae) from California and Arizona by laboratory bioassays. Newly emerged first instars were sprayed with aqueous serial dilutions of spiromesifen and evaluated for toxicity to establish baseline susceptibility data. Interpopulation variability in susceptibility to spiromesifen was observed among the natural populations of whiteflies up to 29-fold; however, there was only 30-fold difference in susceptibility among natural and resistant populations tested. In general, spiromesifen was quite toxic to first instars across most of their geographic range, with LC50 values ranging from 0.210 to 6.08 microg (AI)/ml. The magnitude of variation was smaller among the three-resistant strains. These results suggest that the observed variability reflect natural variation in spiromesifen susceptibility among all the test populations, possibly due to previous exposure to insecticides at each location. The effectiveness of spiromesifen also was evaluated against all immature stages of whiteflies from three field and two resistant strains. Spiromesifen was significantly more active against early instars of whiteflies based on lower LC50 values recorded compared with the fourth instars. Spiromesifen was effective against the resistant strains including a Q-biotype of B. tabaci from Spain, which is highly resistant to neonicotinoids. Results of this study indicate absence of cross-resistance between spiromesifen and more commonly used neonicotinoids. Our findings suggest that spiromesifen should be considered an ideal candidate for whitefly resistance management programs in rotation with other effective chemistries.

AN - 70385037; 18330132 AB - Transgenic cotton, Gossypium hirsutum L., lines expressing both Cry1F and Cry1Ac insecticidal proteins from Bacillus thuringiensis (Bt) have been commercially available in the United States since 2005. Both Bt proteins are highly effective against tobacco budworm, Heliothis virescens (F.), and other lepidopteran pests of cotton. Although CrylAc has been available in Bt cotton since 1996, the Cry1F component is relatively new. As part of the proactive resistance management program for Cry1F/Cry1Ac cotton, a susceptibility-monitoring program is being implemented. Baseline variation in the susceptibility to Cry1F in field populations of tobacco budworm was measured. There was a three-fold variation in the amount of Cry1F needed to kill 50% of the neonates from 15 different field populations from the southern and central United States. Future variation in susceptibility of tobacco budworm populations to Cry1F or even resistance evolution could be documented based on this baseline data. A candidate diagnostic concentration was determined that may be efficiently used to identify individuals that potentially carry major alleles conferring field-relevant resistance to Cry1F before such alleles spread through field populations.

AN - 70381683; 18330123 AB - We compared the effectiveness of a dry collection cup (with an insecticide killing strip) to a wet collection cup (containing antifreeze) for use with Lindgren multiple-funnel traps in catching several common species of bark and wood-boring beetles, and their associates in southern pine forests. All traps were baited with either the binary combination of ethanol and (-)-alpha-pinene or the quaternary combination of (+/-)-ipsenol, (+/-)-ipsdienol, ethanol, and (-)-alpha-pinene. We found that cup treatment had little, if any, effect on catches of Ips avulsus (Eichhoff) and I. grandicollis (Eichhoff) (Coleoptera: Scolytidae), Alaus myops (F.) (Elateridae), Chalcophora Solier species (Buprestidae), Temnochila virescens (F.) (Trogositidae), and Lasconotus Erichson species (Colydiidae). In contrast, catches of the following species were significantly less (by 40-97%) in traps with dry cups than in traps with wet cups: Hylobius pales Herbst and Pachylobius picivorus LeConte (Curculionidae); Buprestis lineata F. (Buprestidae); Acanthocinus obsoletus (Olivier), Arhopalus rusticus nubilus (LeConte), Monochamus titillator (F.) and Xylotrechus sagittatus sagittatus (Cerambycidae); Hylastes porculus Erichson and Xyleborinus saxeseni (Ratzeburg) (Scolytidae); and Thanasimus dubius (F.) (Cleridae). The same was true in at least one experiment for the following species: Dendroctonus terebrans (Olivier), Hylastes salebrosus Eichhoff, Hylastes tenuis Eichhoff, and Xylosandrus crassiusculus (Motschulsky) (Scolytidae). We conclude that cup treatment can have a significant impact on catches of some arboreal beetles in baited multiple-funnel traps. Anyone using multiple-funnel traps to capture arboreal beetles should evaluate the potential impacts arising from their choice of collection cup treatment to their trapping objectives and expectations. The issue of cup treatment may be particular important at low population levels when maximum trap efficiency is required such as in the detection of exotic insects at ports-of-entry and within quarantine and containment zones.

AN - 70313093; 18266076 AB - Cotton bolls were inoculated with a green fluorescent protein (GFP)-expressing Aspergillus flavus (strain 70) to monitor fungal growth, mode of entry, colonization of cottonseeds, and production of aflatoxins. The GFP strain and the wild-type did not differ significantly in pathogen aggressiveness as indicated by similar reductions in inoculated locule weight. GFP fluorescence was at least 10 times higher than the blue green yellow fluorescence (BGYF) produced in response to infection by A. flavus. The GFP produced by the strain made it possible to identify and monitor specific plant tissues colonized by the fungus. For example, the inner seed coat and cotyledon were colonized by the fungus within 72 h of inoculation and the mode of entry was invariably through the porous chalazal cap in intact seeds. The amount of GFP fluorescence was shown to be an indicator of fungal growth, colonization and, to some extent, aflatoxin production. The A. flavus strain expressing GFP should be very useful for rapidly identifying cotton lines with enhanced resistance to A. flavus colonization developed through genetic engineering or traditional plant breeding. In addition, development of GFP expressing A. flavus strain provides an easy and rapid assay procedure for studying the ecology, etiology, and epidemiology of cotton boll rot caused by A. flavus resulting in aflatoxin contamination.

AN - 70311939; 18286406 AB - Cyclodextrins, cyclic oligosaccharides composed of amylose subunits, are known to interact with mycotoxins. The interactions may be useful to analytical chemists by altering the properties of the mycotoxin of interest, namely the chromatographic properties, electrophoretic properties, fluorescence, or absorption of these fungal metabolites. Practical applications of these effects have been the incorporation of cyclodextrins into high-performance liquid chromatography and capillary electrophoresis methods for mycotoxin detection. Specific mycotoxins include those with a native fluorescence such as the aflatoxins, ochratoxin A (OTA) and zearalenone (ZEN) as well as those that can be rendered fluorescent through derivatization, such as T-2 toxin. The literature describing the applications of cyclodextrins in mycotoxin analysis is reviewed and an attempt to extend the use of cyclodextrins to the detection of labelled T-2 toxin is presented. Twenty cyclodextrins were evaluated for their ability to enhance the fluorescence emission of T-2 toxin derivatized with pyrene-1-carbonyl cyanide (T2-Pyr). This evaluation revealed that heptakis (2,6-di-O-methyl)-beta-cyclodextrin (DIMEB), in particular, enhanced T2-Pyr fluorescence. DIMEB was used as a buffer modifier in a capillary electrophoresis-laser-induced fluorescence (CE-LIF) method for detecting T-2 in maize. Because of the effects that certain cyclodextrins have, especially under aqueous conditions, they may make useful additives for a variety of mycotoxin analytical methods.

AN - 70289085; 18260816 AB - As part of the process for developing risk-based performance standards for egg product processing, the United States Department of Agriculture (USDA) Food Safety and Inspection Service (FSIS) undertook a quantitative microbial risk assessment for Salmonella spp. in pasteurized egg products. The assessment was designed to assist risk managers in evaluating egg handling and pasteurization performance standards for reducing the likelihood of Salmonella in pasteurized egg products and the subsequent risk to human health. The following seven pasteurized liquid egg product formulations were included in the risk assessment model, with the value in parentheses indicating the estimated annual number of human illnesses from Salmonella from each: egg white (2636), whole egg (1763), egg yolk (708), whole egg with 10% salt (407), whole egg with 10% sugar (0), egg yolk with 10% salt (11), and egg yolk with 10% sugar (0). Increased levels of pasteurization were predicted to be highly effective mitigations for reducing the number of illnesses. For example, if all egg white products were pasteurized for a 6-log(10) reduction of Salmonella, the estimated annual number of illnesses from these products would be reduced from 2636 to 270. The risk assessment identified several data gaps and research needs, including a quantitative study of cross-contamination during egg product processing and characterization of egg storage times and temperatures (i) on farms and in homes, (ii) for eggs produced off-line, and (iii) for egg products at retail. Pasteurized egg products are a relatively safe food; however, findings from this study suggest increased pasteurization can make them safer.

AN - 70283886; 18260811 AB - Antimicrobial resistance is a growing concern for public and animal health. Threats to public health could come from the transfer of pathogens from animals to people via indirect contact such as through food or by direct contact with animals. In addition, concern has been raised for the potential transfer of resistance determinants from animals to humans through commensal bacterial flora such as Escherichia coli. Isolates of E. coli and Salmonella spp. from dairy cows on farms in 21 states were evaluated for resistance to a panel of 16 antimicrobial drugs. Resistance patterns for E. coli were compared to those of Salmonella spp. when they were isolated concurrently on the same farm or from the same fecal sample. Overall, most of the E. coli isolates (85.3%) and Salmonella spp. isolates (87.2%) were susceptible to all antimicrobials in the panel. The resistance profiles for E. coli with and without concurrent isolation of Salmonella were comparable with the exception of tetracycline resistance, which was more common among the E. coli isolated with Salmonella spp. The resistance patterns for E. coli and Salmonella spp. isolated concurrently were not significantly different for any of the antimicrobials evaluated. The data from this study demonstrate that the majority of commensal E. coli and Salmonella spp. recovered from feces of dairy cows harbored no resistance to a broad range of antimicrobial drugs. Further studies are indicated to better understand the factors that influence the frequency of resistance in commensal E. coli and Salmonella spp. on dairy operations.

AN - 70250944; 17897669 AB - The endophytic fungus, Muscodor albus produces several volatile compounds (alcohols, esters, ketones, acids and lipids) that are biocidal for a range of organisms including plant pathogenic bacteria and fungi, nematodes and insects. We studied the effects of these volatiles on 3-day-old potato tuber moth larvae within infested tubers inside sealed chambers. The length of exposure to M. albus significantly affected mortality of larvae, calculated as percentage of larvae failing to survive to the adult stage. Exposure durations of 3, 7, or 14 days at 24 degrees C followed by incubation in fresh air at 27 degrees C until emergence resulted in mortalities of 84.2, 95.5 and 99.6%, respectively. However, the longer exposures also resulted in increased levels of carbon dioxide (CO(2)) that are unacceptable for tuber storage. Effects of M. albus on larval survival was also monitored at 10, 15 and 24 degrees C, using an exposure duration of 7 days followed by incubation in clean air at 27 degrees C until emergence. Mortality of larvae was sharply reduced at the lower temperatures resulting in 50.8, 76.8, and 95.4% mortality, respectively. Tuber storage conditions, especially cooling rates, are discussed with respect to using M. albus as a fumigant without simultaneously producing unacceptable (for tuber storage) levels of CO(2).

AN - 70241735; 18069983 AB - To evaluate direct plating methods for the estimation of Salmonella load in poultry carcass rinses. Two direct plating tools, the spiral plate count method (SPCM) and the hydrophobic grid membrane filtration (HGMF) method, were adapted to support quantification of Salmonella during poultry processing. Test samples consisted of 180 broiler carcasses from a commercial abattoir, 60 from each of three points in the processing line [pre-inside-outside bird wash (pre-IOBW), prechill and postchill]. The SPCM was used to estimate Salmonella load in pre-IOBW rinses, while HGMF was used to estimate Salmonella levels in prechill and postchill rinses. Carcass rinses were also evaluated for Salmonella prevalence by enrichment methods. Mean prevalences of Salmonella were 95%, 100% and 41.7%, and the geometric mean loads were 3.7 x 10(1), 5.6 x 10(0) and 5.0 x 10(-2) CFU ml(-1) for pre-IOBW, prechill and postchill rinses, respectively. The methods described are useful for estimating the concentration of viable and typical Salmonella in poultry carcass rinses. Direct plating enumeration methods can facilitate the monitoring of Salmonella load on poultry carcasses throughout the production process, and the evaluation of new processing intervention strategies.

AN - 70186001; 17987331 AB - The complete sequence of the pha locus responsible for the biosynthesis of poly(hydroxyalkanoates) (PHAs) in Pseudomonas corrugata 388 was determined. As with the other known pseudomonad pha gene loci, the one in P. corrugata 388 also consists of phaC1 (1,680 bps; PHA synthase 1), phaZ (858 bp; PHA depolymerase) and phaC2 (1,683 bp; PHA synthase 2) genes. A BLAST search showed that the nucleotide sequences of these genes and the amino-acid sequences of their respective gene products are homologous to those of P. corrugata CFBP5454 and P. mediterranea CFBP5447. A putative intrinsic transcription terminator consisting of a dyad symmetry (24 bp; Delta G = -41.8 kcals) that precedes a stretch of dA residues was located in the phaC1-phaZ intergenic region. P. corrugata mutant-clones XI 32-1 and XI 32-4 were constructed in which this intergenic region was replaced with a selectable kanamycin-resistance gene. These mutant clones when grown on oleic acid for 48 h showed 4.7-to 7.0-fold increases of phaC1 and phaC2 relative expression in comparison to the initial inoculants, whereas the parental strain showed only 1.2- to 1.4-fold increases. Furthermore, in comparison to parental P. corrugata with only a few large PHA inclusion bodies, the mutants grown on oleic acid produce numerous smaller PHA granules that line the periphery of the cells. With glucose as a substrate, XI 32-1 and XI 32-4 clones produce mcl-PHA with a high content (26-31 mol%) of the mono-unsaturated 3-hydroxydodecenoate as a repeat-unit monomer. Our results show for the first time the effects of the phaC1-phaZ intergenic region on the substrate-dependent temporal expression of phaC1 and phaC2 genes, the repeat-unit composition of mcl-PHA, and the morphology of the PHA granules.

This heterofermentative, facultative anaerobe can utilize xylose as a sole carbon source and tolerates up to 12% ethanol. Carbohydrate utilization (API, Biomerieux) and Phenotype Microarrays+ (PM, Biolog) analyses indicated that the strain is able to metabolize a broad spectrum of carbon sources including various monosaccharides (C5 and C6), disaccharides and oligosaccharides, with better rates under anaerobic conditions. In pH-controlled bioreactors, the bacterium consumed xylose and glucose simultaneously at high concentrations (125gL super(-1), pH 6.0). The major fermentation products were lactate (52gL super(-1)), acetate (26gL super(-1)) and ethanol (12gL super(-1)). The strain ferments glucose alone (pH 4.0) into lactate and ethanol with a molar ratio of 1.03:1. This strain will be further explored via genetic engineering for potential applications in biomass conversion.

Herbivory was mediated on individual trees using regular applications of the insecticide acephate during a 2-year period to minimize populations of O. vitiosa and later the phloem-feeding psyllid, Boreioglycaspis melaleucae. Half of the trees also received drip irrigation to evaluate the influence of water on plant responses to herbivory. Insecticide-protected trees grew in height nearly six times faster and became 108% taller. In contrast, unprotected trees produced only 19% as much woody biomass, 13% as much leaf biomass, and 0.9% as much seed as protected trees. The mean (+/-SE) of total above ground biomass was 873.1 +/- 191.4 g in unsprayed trees and 3856.2 +/- 491.5 g in sprayed trees. Unprotected trees produced more stem tips per unit of height, resulting in a more bushy structure. Greater amounts of water increased leaf biomass, but all other plant variables were influenced most by herbivory. The seed-fueled invasive capacity of melaleuca will probably be reduced in areas favorable to the biological control agents, especially O. vitiosa.

In this study, we investigated the potential of using entomopathogenic nematodes to control C. nenuphar further by evaluating (1) field efficacy of late-term nematode applications, i.e., that target C. nenuphar after the onset of adult emergence, (2) control C. nenuphar larvae in an alternate host, i.e., wild plum, Prunus angustifolia, and (3) laboratory virulence of different Steinernema carpocapsae and S. riobrave strains. In 2004 and 2005, late-term applications of S. carpocapsae (All strain) and S. riobrave (355 strain) in a peach orchard in Quincy, Florida failed to cause any measurable control. In field tests targeting C. nenuphar larvae in a wild plum thicket (Byron, Georgia), S. riobrave (355 strain) caused 100% control (both years), and S. riobrave (3-8b strain) caused 98.6% and 87.9% control in 2005 and 2006, respectively. Applications in alternate hosts could reduce C. nenuphar immigration into the orchard. Laboratory experiments detected differential virulence to C. nenuphar larvae in S. carpocapsae (All strain) and six strains of S. riobrave; among the most virulent were the 3-2, 3-3, and 355 strains of S. riobrave. Pathogenicity to adult C. nenuphar in the laboratory was not detected in five S. riobrave strains, but was detected in four S. carpocapsae strains (All, Agriotos, Italian and Sal) but not in two others (Kapow and Mexican). We conclude that soil applications with entomopathogenic nematodes can cause high levels of C. nenuphar control in peach or alternate hosts, but timing of application and the choice of nematode species or strain can be important.

Using a common approach for constructing dynamic models for predicting Clostridium perfringens growth in ready-to-eat uncured beef during cooling, there was no appreciable difference between the models' predictions when the population of cells was within the lag or exponential phases of growth. The developed models can be used for designing safe cooling processes; however, the discrepancies between predicted and observed growths obtained in this study, together with discrepancies reported in other papers using the same, or similar methodology as used in this paper, point to a possible inadequacy of the derived models. In particular, the appropriateness of the methodology depends on the appropriateness of using estimated growth kinetics obtained from experiments conducted in isothermal environments for determining coefficients of differential equations that are used for predicting growth in constantly changing (dynamic) environments. The coefficients are interpreted as instantaneous specific rates of change that are independent of prior history. However, there is no known scientific reason that would imply the truth of this assumption. Incorporating a different, less restrictive assumption, allowing for a dependency on the prior history of cells for these kinetic parameters, might lead to models that provide more accurate estimates of growth. For example, a cooling scenario of 54.4-27 super(o)C in 1.5h, the average predicted and observed log sub(1) sub(0) relative growths were 1.1log sub(1) sub(0) and 0.66log sub(1) sub(0), respectively, a difference of 0.44log sub(1) sub(0) sub(,) whereas, when assuming a particular dependency of history, the predicted value was 0.8log sub(1) sub(0). More research is needed to characterize the behavior of growth kinetic parameters relative to prior history in dynamic environments.

Imaging of chicken fillets is often dominated by multiple scattering properties of the fillets. Thus, resulting images from multiple scattering are diffused, scattered, and low contrast. In this study, a combination of transmittance and reflectance hyperspectral imaging, which is a non-ionized and non-destructive imaging modality, was investigated as an alternative method to conventional transmittance x-ray imaging, which is an ionizing imaging modality. As a way of reducing the influence of light scattering on images and thus increasing the image contrast, the use of a structured line light was examined along with an image formation model that separated undesirable lighting effects from an image. The image formation model, based on an illumination-transmittance model, was applied for correcting non-uniform illumination effects so that embedded bones were more easily detected by a single threshold. An automated image processing algorithm to detect bones was also proposed. Experimental results with chicken breast fillets and bone fragments are provided. The detection accuracy of the developed technology was 100%. The false-positive rate was 10%.

However, a rapid assessment strategy for quantifying the rate and spatial distribution of conservation tillage practices is lacking. This study was designed to evaluate the sensitivity of a remotely derived crop residue cover index for depicting conventional tillage (CT), strip tillage (ST), and no-tillage (NT) systems in a cotton-corn-peanut rotation in the southeastern Coastal Plain. Treatments consisted of CT (rip and bed operation), NT, NT with subsoiling, and ST. Remotely sensed data were acquired three times prior to canopy closure, using a handheld multispectral radiometer (485 to 1,650 nm) and thermal imager (7,000 to 14,000 nm). Using a combination of visible and near-infrared spectra, a crop residue cover index was calculated and evaluated. Results showed that crop residue cover is greatest in years planted with peanut or cotton--likely due to the later winter cover crop termination date compared to years when corn is planted. The crop residue cover index outperformed the thermal infrared, accurately separating conventional from conservation tillage treatments in four out of six data acquisitions in 2004 and 2006. Differentiation among conservation tillage treatments was inconsistent. Regression analyses showed that a strong linear relationship existed between the crop residue cover index and measured crop residue cover (r super(2) = 0.51 to 0.86, alpha = 0.10). These data suggest that remotely sensed data may be used as a rapid, field-scale indicator of conservation tillage adoption. Rapid assessment methodologies are necessary to quantify the impact of conservation practice adoption on water quality/quantity, assess adoption rates, and improve the placement of conservation tillage practices at local, watershed and regional scales.

Coshocton wheel samplers were used to collect runoff samples from no-till and chisel-till watersheds in corn (Zea mays) and soybean (Glycine max) rotations over 13 years. Samples were analyzed for SOC, N, P, K, and soil losses. The SOC losses, ranging from 0 to 357kgha-1event-1, were correlated (r2=0*80-0*94) in power law relationships with N, P, K, soil loss, and runoff. Two events occurring in corn when soybean and cover crop residue were present in no-till had combined SOC transport of 460kgha-1, nearly double the no-till losses of a previous 11-year period and 20 times higher than chisel-till in the same events. Infrequent, extreme transport events that are not well characterized empirically, particularly in no-till, can strongly influence hydrologic C transport from agriculture watersheds.

Extensive numbers of validated SNPs with known allele frequencies are essential to construct genotyping assays with broad utility. We describe an economical, efficient, single-step method for SNP discovery, validation and characterization that uses deep sequencing of reduced representation libraries (RRLs) from specified target populations. Using nearly 50 million sequences generated on an Illumina Genome Analyzer from DNA of 66 cattle representing three populations, we identified 62,042 putative SNPs and predicted their allele frequencies. Genotype data for these 66 individuals validated 92% of 23,357 selected genome-wide SNPs, with a genotypic and sequence allele frequency correlation of r = 0.67. This approach for simultaneous de novo discovery of high-quality SNPs and population characterization of allele frequencies may be applied to any species with at least a partially sequenced genome.

In a 28-d experiment, 180 pigs (initial BW 6.3 kg) were fed 0, 0.05, 0.1, 0.2, or 0.4% sodium butyrate, or 110 mg/kg of dietary tylosin. There was no effect of dietary sodium butyrate or tylosin on overall G:F, but there was a linear trend (P < 0.07) toward decreased ADFI and ADG as levels of sodium butyrate increased. In a second 28-d experiment, 108 pigs (initial BW 6.3 kg) were assigned to 1 of 3 dietary treatments: 1) no antibiotics, 2) 0.2% sodium butyrate, or 3) 55 mg/kg of carbadox. On d 14, a subset of pigs from the no-antibiotic and butyrate treatment groups was challenged with E. coli LPS or injected with sterile saline in a 2 x 2 factorial arrangement ( plus or minus LPS challenge; plus or minus dietary butyrate; n = 6 pigs/treatment group). Four hours after LPS challenge, blood samples were obtained, and samples of LM, liver, and ileum were collected for gene expression analysis. Serum samples were analyzed for IL-6, tumor necrosis factor alpha (TNF alpha ), alpha sub(1)-acid glycoprotein, cortisol, IGF-I, insulin, and metabolites. The relative abundance of tissue cytokine and IGF-I mRNA was measured by real-time PCR. Feeding diets containing sodium butyrate or carbadox did not alter ADG or ADFI compared with pigs fed the control diet. From d 0 to 14, pigs fed diets containing 0.2% sodium butyrate had decreased (P < 0.05) ADG and tended (P < 0.06) to have decreased G:F compared with animals fed diets containing carbadox. Challenge with LPS increased (P < 0.05) serum cytokines and cortisol and decreased (P < 0.05) serum glucose and triglycerides. Injection with LPS increased (P < 0.05) the relative abundance of hepatic IL-6 and TNF alpha mRNA, increased (P < 0.05) LM TNF alpha mRNA content, and decreased (P < 0.05) IGF-I mRNA in LM. For serum cortisol, there was an interaction (P < 0.05) between dietary butyrate and LPS. The increase in serum cortisol attributable to LPS was greater (P < 0.05) in pigs fed butyrate than in pigs fed the control diet. There tended (P < 0.10) to be an interaction between LPS and diet and for butyrate to increase the relative abundance of IL-6 mRNA in LM. Carbadox did not alter cytokine or IGF-I mRNA or serum metabolites, but did decrease (P < 0.05) serum TNF alpha .

However, plot data from rainfall simulator experiments and natural rainfall events have shown that infiltration rates can increase with increasing rainfall rate instead of decreasing with time or infiltrated depth, as predicted by infiltration models. This has been hypothesized to be a function off the spatial variability of the infiltration capacity across the area. In this article, an exponential model relating steady-state infiltration rate with rainfall intensity and the average areal infiltration rate when the area under consideration is contributing to runoff is evaluated using data from variable-intensity rainfall simulator experiments. The experiments were conducted on five rangeland vegetation-soil associations at the Walnut Gulch Experimental Watershed in southeastern Arizona. The results from 19 rainfall simulation runs show that the increase in infiltration rate with increasing rainfall intensity can be significant and that the exponential model represents the relationship between steady-state infiltration and rainfall intensity. The exponential model coupled with a kinematic wave model also represents the hydrographs better than the Green-Ampt Mein-Larsen infiltration model coupled with the same routing model The time to the start of runoff is influenced more by rainfall intensity than by initial soil moisture conditions, particularly when the initial rainfall intensity was high. The rapid time to steady-state runoff at the beginning of the simulation run of the observed runoff hydrographs suggests that the infiltration rates become constant more quickly than infiltration theory would suggest.

Plasmid pGAPZ alpha C/Psd1, a binary vector encoding the constitutive expression of the gene for the pea defensin Psd1, was used to transform the yeast Pichia pastoris, and transformed strains were evaluated for enhancing biocontrol potential by Psd1. Two P. pastoris strains, X-33 and GS115, were successfully transformed by electroporation and produced the active rPsd1 peptide. Nontransformed strain X-33 grew faster than strain GS115 in Golden Delicious apple wounds and was chosen as the host for plasmid pGAPZaC/Psd1 in biocontrol tests. The severity and incidence of blue mold decay caused by Penicillium expansion were significantly reduced on apples treated with X-33(pGAPZ alpha C/Psd1/X-33) when compared to apples inoculated with this fungus alone or in combination with the nontransformed parental strain X-33, or the X-33(pGAPZ alpha C/X-33) recombinant containing the empty binary vector. Four selected transformants reduced decay in repeated studies, but were effective only when applied at a lower (6.3 x 10 super(5) CFUmL super(-1)) cell concentration. This study demonstrates the potential of Psd1 for enhancing suppression of postharvest diseases. However, the full potential of the Psd1 defensin may be achieved after optimizing its expression and activity on the fruit.

Significant advantages of KS over the commonly used sodium bicarbonate, which similarly improved fungicide performance, are the relatively low salt concentration of KS, the absence of sodium, and its lower pH, so disposal of used KS solutions would raise fewer regulatory issues. The influence of KS concentration and pH (pH 4-9) on the germination of spores of Penicillium digitatum was determined alone or in combination with four postharvest citrus fungicides, imazalil (IMZ), thiabendazole (TBZ), pyrimethanil, and fludioxonil. The EC sub(95) concentrations of KS to inhibit spore germination were lowest from pH 4-6. To control green mold on inoculated fruit, KS was compatible with these fungicides and consistently improved their performance. KS alone or fungicide-KS solutions were more effective when heated. The combination of KS and sodium bicarbonate was only moderately better than either alone. Green mold caused by an isolate of P. digitatum resistant to IMZ and TBZ was effectively controlled when KS was added to a heated IMZ or TBZ solutions. Heat, but not KS, increased residues of all of the fungicides in oranges. Sour rot, caused by Geotrichum citri-aurantii, was reduced from 94.5% among control lemons, to 49.1 and 47.2%, respectively, by 30s immersion in KS or sodium bicarbonate at 1% (wt/vol) at 25 degree C, and to 37.0 and 15.7%, respectively, when these solutions were at 50 degree C.

A few studies have demonstrated a critical role of chemical communication in establishing highly specialized relationships, but the general role for root exudates in structuring the soil fungal community is poorly described. This study demonstrates that two model plant species (Arabidopsis thaliana and Medicago truncatula) are able to maintain resident soil fungal populations but unable to maintain nonresident soil fungal populations. This is mediated largely through root exudates: the effects of adding in vitro-generated root exudates to the soil fungal community were qualitatively and quantitatively similar to the results observed for plants grown in those same soils. This effect is observed for total fungal biomass, phylotype diversity, and overall community similarity to the starting community. Nonresident plants and root exudates influenced the fungal community by both positively and negatively impacting the relative abundance of individual phylotypes. A net increase in fungal biomass was observed when nonresident root exudates were added to resident plant treatments, suggesting that increases in specific carbon substrates and/or signaling compounds support an increased soil fungal population load. This study establishes root exudates as a mechanism through which a plant is able to regulate soil fungal community composition.

Here we describe and characterize a novel HST designated SnTox3, and the corresponding wheat sensitivity/susceptibility gene identified on chromosome arm 5BS, which we designated as Snn3. SnTox3 is a proteinaceous necrosis-inducing toxin between 10 and 30 kD in size. The S. nodorum isolates Sn1501 (SnToxA-, SnTox2+, and SnTox3+), SN15 (SnToxA+, SnTox2+, and SnTox3+), and SN15KO18, a strain of SN15 with a disrupted form of SnToxA, were evaluated on a population of wheat recombinant inbred lines. A compatible Snn3-SnTox3 interaction played a significant role in the development of disease caused by isolates Sn1501 and SN15KO18, with Snn2 being epistatic to Snn3. Snn3 was not significantly associated with disease caused by SN15 presumably due to the major effects observed for Snn2 and Tsn1, which were largely additive. This work introduces a fourth HST produced by S. nodorum and builds on the notion that the S. nodorum-wheat pathosystem is largely based on multiple host-toxin interactions that follow an inverse gene-for-gene scenario.

Controlling the spread of this disease is hindered by the lack of sensitive, selective, and rapid detection methods for M. avium subsp. paratuberculosis. By using a recently optimized sandwich immunoassay (B. J. Yakes, R. J. Lipert, J. P. Bannantine, and M. D. Porter, Clin. Vaccine Immunol. 15:227-234, 2008), which incorporates a new monoclonal antibody for the selective capture and labeling of M. avium subsp. paratuberculosis and surface-enhanced Raman scattering for sensitive readout, detection limits of similar to 630 and similar to 740 M. avium subsp. paratuberculosis cells/ml are achieved in phosphate-buffered saline and whole milk samples, respectively, after spiking with heat-treated M. avium subsp. paratuberculosis. Surprisingly, these detection limits are 3 orders of magnitude lower than expected based on theoretical predictions. Experiments designed to determine the origin of the improvement revealed that the major membrane protein targeted by the monoclonal antibody was present in the sample suspensions as shed protein. This finding indicates that the capture and labeling of shed protein function as a facile amplification strategy for lowering the limit of detection for M. avium subsp. paratuberculosis that may also be applicable to the design of a wide range of highly sensitive assays for other cells and viruses.

We tested the hypothesis that developmental TCDD exposure would disrupt cardiac ECM expression and be associated with changes in cardiac morphology in adulthood. In one study, time-pregnant C57BL/6 mice were dosed with corn oil or 1.5, 3.0, or 6.0 mu g TCDD/kg on gestation day (GD) 14.5 and sacrificed on GD 17.5, when changes in fetal cardiac mRNA expression were analyzed using quantitative PCR. TCDD induced mRNA expression of genes associated with ECM remodeling (matrix metalloproteinase 9 and 13, preproendothelin-1 [preproET-1]), cardiac hypertrophy (atrial natriuretic peptide, beta -myosin heavy chain, osteopontin), and aryl hydrocarbon receptor (AHR) activation (cytochrome P4501A1, AHR repressor). Further, all TCDD-induced changes required the AHR since gene expression was not altered in AHR knockout fetuses. In a second study, time-pregnant mice were treated with corn oil or 6.0 mu g TCDD/kg on GD 14.5, and male offspring were assessed for changes in cardiac gene expression and cardiac and renal morphology at 3 months. All TCDD-induced changes in cardiac gene expression observed fetally, except for preproET-1, remained induced in the hearts of adult male offspring. Adult male offspring of TCDD-exposed dams also displayed cardiac hypertrophy, decreased plasma volume, and mild hydronephrosis. These results demonstrate that in utero and lactational TCDD exposures alter cardiac gene expression and cardiac and renal morphology in adulthood, which may increase the susceptibility to cardiovascular dysfunction.

Biomass energy and biomass ethanol are key components in this pursuit. Vast amounts of biomass feedstock will be needed to produce sufficient ethanol to meet any of the numerous target production goals. The Billion Ton Vision suggests one billion tons of biomass is needed annually to meet the 30x30 goal (to replace 30% of 2004 levels of fossil transportation fuel use with ethanol by the year 2030). Great advances in technology will be required to produce this enormous quantity of biomass sustainably. These advances will not come about through ill-coordinated, competitive efforts. On the contrary, the problem of sustainably meeting the biofuel feedstock demand while continuing to meet traditional demands for agricultural output is so great that we need to focus all our energies on establishing complementary public energy policy based on facts and candid analysis; on crafting cooperative, coordinated energy goals across agencies; and on creating enthusiastic, dedicated teams of researchers and educators to develop and deploy existing and new technologies.

A class of aromatic compounds in grapefruit is the furanocoumarins (FCs), and their metabolism in humans is centrally involved in the 'grapefruit/drug interactions.' Thus far, the metabolism by fungi of the major FCs in grapefruit, including 6', 7'-epoxybergamottin (EB), 6', 7'-dihydroxybergamottin (DHB), and bergamottin (BM), has received little attention. In this study, Aspergillus niger was observed to convert EB into DHB and a novel water-soluble metabolite (WSM). Bergaptol (BT) and BM were also metabolized by A. niger to the WSM, which was identified as BT-5-sulfate using mass spectrometry, UV spectroscopy, chemical hydrolysis, and super(1)H and super(13)C nuclear magnetic resonance spectroscopy. Similarly, the fungus had a capability of metabolizing xanthotoxol (XT), a structural isomer of BT, to a sulfated analog of BT-5-sulfate, presumably XT-8-sulfate. A possible enzyme-catalyzed pathway for the grapefruit FC metabolism involving the cleavage of the geranyl group and the addition of a sulfate group is proposed.

Feed consumption and weight gain were highest (P 0.05) among strains when final weight was used as a covariate. USDA103, USDA303, and USDA102 X USDA103 strains had higher (P < 0.01) protein efficiency ratios compared to USDA102. In a second study, the four groups of catfish (22.2 c 1.9 g/fish) were challenged with Edwardsiella ictaluri and mortality was recorded for 3 wk postchallenge. Survival was higher (P < 0.02) for USDA303 and USDA102 X USDA103 fish. Results of these studies demonstrate that the USDA103 and USDA303 strains of catfish were superior in growth performance. Results of the bacterial challenge show that the USDA303 and USDA102 X USDA103 strains of fish exhibited increased survival. Continued selection of the USDA103 line and crossing this line of fish with lines of fish such as the USDA102 strain may produce fish with desirable growth and disease characteristics.

Odion and Hanson's results are predicated on BAER soil burn severity maps, which are based primarily on fire effects to soil, not vegetation. Odion and Hanson, and we fear others as well, are misinformed as to the nature of the BAER severity mapping process, and proper applications of BAER soil burn severity maps. By comparing the BAER soil burn severity maps to a true vegetation burn severity measure (RdNBR) calibrated by field data, we show that the area in the high soil burn severity class for the three fires analyzed by Odion and Hanson is substantially less than the area of stand-replacing fire, and that BAER maps--especially hand-derived maps such as those from two of the three fires--also greatly underestimate the heterogeneity in vegetation burn severity on burned landscapes. We also show that, contrary to Odion and Hanson's claims, Fire Return Interval Departure (FRID) is strongly correlated with fire severity in conifer stands within the perimeter of the Fire.

Treatments included incorporating flowering Brassica napus cv. Dwarf Essex canola or B. juncea cv. Cutlass mustard and laying black polyethylene mulch at incorporation or 1 month after incorporation, methyl bromide, and a nontreated control. In both years, glucosi-nolates were identified and quantified in the shoots and roots of the flowering plants. In both years, the total concentration of glucosinolates incorporated per square meter was significantly higher for B. juncea than for B. napus. Isothiocyanates were inconsistently detected in the amended soils and none were detected more than 12 days postincorporation. After incorporation in 2004 and 2005, amended plots had higher populations of Fusarium oxysporum and Pythium spp. than the methyl bromide treatment, and in some treatments, populations were higher than in the control. Fluorescent Pseudomonas spp. were not suppressed in amended soils, and their populations were significantly higher in some amended treatments than those in methyl bromide-treated soils or nontreated control soils. Incidence of damping-off and severity of Fusarium wilt on seedless watermelon cv. Tri-X 313, which is susceptible to Fusarium wilt, were not consistently lower in brassica-amended soils or methyl bromide-treated plots than in nontreated control plots. Therefore, under spring conditions and methods used in this study, neither biofumigation nor methyl bromide fumigation in coastal South Carolina was an effective disease management tool for two soilborne pathogens of watermelon.

Ammonia emissions were estimated with a process-based mechanistic model integrating ammonia chemistry of the lagoon and interfacial transport characteristics between air and water. This improved model incorporated the effect of internal bubble production and continuously variable wind speed on ammonia volatilization measured at 10 m above the liquid surface (U sub(10)). Model simulations were compared to ammonia emission rates measured simultaneously at three contrasting lagoon scenarios: non-treated lagoon (13,633 kg ha super(-1) year super(-1)), partially pre-treated manure using solid-liquid separation (3,699 kg ha super(-1) year super(-1)), and treated manure using combined solid-liquid separation with nitrogen and phosphorus removal from the liquid (1,311 kg ha super(-1) year super(-1)). The simulations only using average U sub(10) with bubble enhancement or U sub(10) distributions without bubble enhancement produced fluxes 42% and 44% below observed fluxes, respectively. However, the simulated fluxes using the U sub(10) distributions along with bubble enhancement for the non-treated lagoon during warm seasons closely matched the observed fluxes (y = 1.04x, with R super(2) = 0.76). Ammonia emissions would be significantly underpredicted if bubbling-enhanced mass transport was not taken into account during warm seasons, as demonstrated by the improved process model and evidenced by the observed fluxes.

Despite the breadth of research regarding the spatial controls on fire regime variability, few datasets are available with sufficient resolution to test spatially explicit hypotheses. We used a spatially distributed network of georeferenced fire-scarred trees to investigate the spatial structure of fire occurrence at multiple scales. Mantel's tests and geostatistical analysis of fire-occurrence time series led to inferences about the mechanisms that generated spatial patterns of historical fire synchrony (multiple trees recording fire in a single year) in eastern Washington, USA. The spatial autocorrelation structure of historical fire regimes varied within and among sites, with clearer patterns in the complex rugged terrain of the Cascade Range than in more open and rolling terrain further north and east. Results illustrate that the statistical spatial characteristics of fire regimes change with landform characteristics within a forest type, suggesting that simple relationships between fire frequency, fire synchrony, and forest type do not exist. Quantifying the spatial structures in fire occurrence associated with topographic variation showed that fire regime variability depends on both landscape structure and the scale of measurement. Spatially explicit fire-scar data open new possibilities for analysis and interpretation, potentially informing the design and application of fire management on landscapes, including hazardous fuel treatments and the use of fire for ecosystem restoration.

The qualitatively different pathogenicity exhibited by the virulent E. carotovora strain and two avirulent strains, a Citrobacter sp. and an Enterobacter cloacae, was examined using digital analysis of photographic evidence of necrosis as well as for carbohydrate, ethane, and ethylene release compared with uninoculated potato tuber slices. Visual scoring of necrosis was superior to digital analysis of photographs. The release of carbohydrates and ethane from potato tuber slices inoculated with the soft rot necrosis-causing Erwinia was significantly greater than that of potato tuber slices that had not been inoculated or that had been inoculated with the nonpathogenic E. cloacae and Citrobacter sp. strains. Interestingly, ethylene production from potato slices left uninoculated or inoculated with the nonpathogenic Citrobacter strain was 5- to 10-fold higher than with potato slices inoculated with the pathogenic Erwinia strain. These findings suggest that (1) carbohydrate release might be a useful measure of the degree of pathogenesis, or relative virulence; and that (2) bacterial suppression of ethylene formation may be a critical step in root rot disease formation.

New tools are needed to quickly assess these losses and provide nutrient managers and conservationists with effective tools to assess the effects of current and alternative management practices on N loss pathways. A new N-Index tool was developed in spreadsheet format, allowing prompt assessments of management practices on agricultural N losses. The N-Index tool was compared with experimental field data and shown to estimate the effects of management practices on N loss pathways (probability, P<0.001). The N-Index correctly assessed the nitrate nitrogen (NO sub(3)-N) leaching losses when tested against measured NO sub(3)-N leaching data and atmospheric N losses collected over multiple years (annual basis) and locations. The N-Index tool was developed with international cooperation from several countries and there is potential to use this tool at the international level.

Nucleotide sequence differences as well as alternative translational start site assignments result in three non-identical protein sequence predictions for this amidase. Therefore, it is prudent to verify the correct phi11 amidase protein sequence, especially since multiple versions of the amidase gene have been subcloned, deletion analysis performed, and their experimental use described. There is also a resurgence of interest in the expression and use of bacteriophage lytic proteins as bactericidal agents and the 11 amidase has a high antimicrobial potential. The correct amidase sequence is identified through a combination of DNA sequence analysis and matrix-assisted laser desorption/ionization-time-of-flight mass spectrometry analysis of the recombinant purified phi11 amidase protein.

An evaluation of IFN- production from somatic cell nuclear transfer (NT)-embryo-derived primary trophectoderm cultures in comparison to trophectoderm cultured from parthenogenote (P) and in vitro matured, fertilized, and cultured (IVP) bovine embryos was performed. In Experiment 1, the success/failure ratio for primary trophectoderm colony formation was similar for IVP and NT blastocysts [IVP = 155/29 (84%); NT 104/25 (81%)], but was decreased (P = .05) for P blastocysts [54/43 (56%)]. Most trophectoderm colonies reached diameters of at least 1 cm within 3-4 weeks, and at this time, 72 hr conditioned cell culture medium was measured for IFN- concentration by antiviral activity assay. The amount of IFN- produced by IVP-outgrowths [4311 IU/mL (n = 155)] was greater (P < .05) than that from NT- [626 IU/mL (n = 104)] and P - [1595 IU/mL (n = 54)] derived trophectoderm. Differential expression of IFN- was confirmed by immunoblotting. In Experiment 2, colony formation was again similar for IVP and NT blastocysts [IVP = 70/5 (93%); NT 67/1 (99%)] and less (P < .05) for P blastocysts [65/27 (70%)]. Analysis of trophectoderm colony size after 23 days in culture showed a similar relationship with P-derived colonies being significantly smaller in comparison to IVP and NT colonies. A differential expression of IFN- was also observed again, but this time as measured over time in culture. Maximal IFN- production was found at day-14 of primary culture and diminished to a minimum by the 23rd day. Mol. Reprod. Dev. 75: 299-308, 2008. Published 2007 Wiley-Liss, Inc.

Tuber initiation stage is the most critical growth stage for water stress. In this paper, effects of different water regimes on tuber yield and quality under different production systems are discussed. Deficit irrigation in general showed negative impact on the tuber yield as well as quality. Soil water management influences the fate and transport of nitrogen in soils, therefore, best management practice of both water and nitrogen are critical to optimize uptake efficiencies and minimize leaching losses.

Sperm osmotolerance (300-3000mOsm/kg) was evaluated after: (1) equilibration times of 2, 10, 45 and 60min at 4 super(o)C versus 21 super(o)C; (2) pre-equilibrating with dimethylacetamide (DMA) or dimethylsulfoxide (Me sub(2)SO) at either 4 super(o)C or 21 super(o)C; and (3) inhibition of the Na super(+)/K super(+) and the Na super(+)/H super(+) antiporter membrane ionic pumps. Sperm viability was assessed using the eosin-nigrosin live/dead stain. Species-specific differences occurred in response to hypertonic conditions with crane sperm remaining viable under extreme hypertonicity (3000mOsm /kg), whereas turkey sperm viability was compromised with only slightly hypertonic (500mOsm/kg) conditions. The timing of spermolysis under hypertonic conditions was also species-specific, with a shorter interval for turkey (2min) than crane (10min) sperm. Turkey sperm osmotolerance was slightly improved by lowering the incubation temperature from 21 to 4 super(o)C. Pre-equilibrating sperm with DMA reduced the incidence of hypertonic spermolysis only in the crane, at both room and refrigeration temperature. Inhibiting the Na super(+)/K super(+) and the Na super(+)/H super(+) antiporter membrane ion pumps did not impair resistance of crane and turkey spermatozoa to hypertonic stress; pump inhibition actually increased turkey sperm survival compared to control sperm. Results demonstrate marked species specificity in osmotolerance between crane and turkey sperm, as well as in the way temperature and time of exposure affect sperm survival under hypertonic conditions. Differences are independent of the role of osmotic pumps in these species.

We evaluated biophysical constraints on leaf expansion in old-growth Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco) trees. Needle elongation rates, plastic and elastic extensibility, bulk leaf water and osmotic potential, bulk tissue yield threshold and final needle length were characterized along a height gradient in crowns of > 50-m-tall trees during the period between bud break and full expansion (May to June). Although needle length decreased with increasing height, there was no height-related trend in leaf plastic extensibility, which was highest immediately after bud break (2.9%) and declined rapidly to a stable minimum value (0.3%) over a 3-week period during which leaf expansion was completed. There was a significant positive linear relationship between needle elongation rates and plastic extensibility. Yield thresholds were consistently lower at the upper and middle crown sampling heights. The mean yield threshold across all sampling heights was 0.12 plus or minus 0.03 MPa on June 8, rising to 0.34 plus or minus 0.03 MPa on June 15 and 0.45 plus or minus 0.05 MPa on June 24. Bulk leaf [Psi] capital pi decreased linearly with increasing height at a rate of 0.004 MPa m super(-1) during the period of most rapid needle elongation, but the vertical osmotic gradient was not sufficient to fully compensate for the 0.015 MPa m super(-1) vertical gradient in [Psi] sub(L), implying that bulk leaf turgor declined at a rate of about 0.011 MPa m super(-1) increase in height. Although height-dependent reductions in turgor appeared to constrain leaf expansion, it is possible that the impact of reduced turgor was mitigated by delayed phenological development with increasing height, which resulted in an increase with height in the temperature during leaf expansion.

M. avium subsp. paratuberculosis is the causative agent of Johne's disease in cattle, and one of the major obstacles in controlling the spread of this disease is the inability to rapidly detect small amounts of bacteria or other diagnostic markers shed during the subclinical stage of infection. This paper details the development and performance of an assay for sonicated M. avium subsp. paratuberculosis lysate that is based on surface-enhanced Raman scattering (SERS). There are two key components of the assay: (i) an immobilized layer of monoclonal antibodies that target a surface protein on the microorganism; and (ii) extrinsic Raman labels (ERLs) that are designed to selectively bind to captured proteins and produce large SERS signals. By correlating the number of M. avium subsp. paratuberculosis bacilli present prior to sonication to the amount of total protein in the resulting sonicate, the detection limit determined for total protein can be translated to the microorganism concentration. These findings yield detection limits of 100 and 200 ng/ml (estimated to be 500 and 1,000 M. avium subsp. paratuberculosis bacilli/ml) for sonicate spiked in phosphate buffer and sonicate spiked in whole milk, respectively. Moreover, the time required to complete the assay, which includes sample preparation, antigen extraction, ERL incubation, and readout, is less than 24 h. The potential for incorporation of this novel assay into diagnostic laboratories is also briefly discussed.

Viburnum is a genus of commonly grown ornamental shrubs known to be susceptible to P. ramorum. The entire genus has been placed on the P. ramorum host list. The range of susceptibility of genotypes in the genus is currently not understood. We evaluated whether or not cultivars in the genus Viburnum differ in susceptibility to P. ramorum in controlled, detached leaf inoculations using two isolates belonging to the two clonal lineages found in Oregon. The genus Viburnum shows remarkable differences in susceptibility to infection by P. ramorum. Viburnum genotypes differed significantly in susceptibility to P. ramorum in detached leaf inoculations. V. x burkwoodii was consistently the most susceptible host genotype, followed by V. plicatum 'Mariesii' and V. len-tago. Most cultivars evaluated for resistance to P. ramorum were not susceptible or developed only small lesions as determined with a detached leaf assay. Our work only provides information on leaf based resistance, and inferences on epidemic development in whole canopies and under field conditions cannot currently be made.

Werres & A.W.A.M. de Cock is the causal agent of sudden oak death in California and Oregon forests and ramorum blight on a broad range of host species in wildlands and nurseries. It is thought to be an introduced pathogen and only three clonal lineages are known (3). The North American lineage (lineage NA1, mating type A2) is responsible for infections in California and Oregon forests. The European lineage (lineage EU1, predominantly A1) is responsible for infections in Europe, but has also been found in nurseries in Oregon and Washington. A third lineage (NA2) has only been isolated in a few instances from nurseries in Washington and California. In June 2006, P. ramorum was isolated from diseased Viburnum tinus, Osmanthus heterophyllus, and O. fragrans cultivars from a Humboldt County retail nursery in northern California. We genotyped isolates and placed them into clonal lineages using microsa-tellite markers developed for P. ramorum (3,4). Genomic DNA was extracted from mycelia with the FastDNA SPIN kit (Q-Biogene, Morgan, Irvine, CA). Primers used were PrMS6, Pr9C3, PrMS39, PrMS43a, PrMS43b, and PrMS45 (3) and 18, 64, and 82 (4). We sized fluorescently labeled amplicons using capillary electrophoresis (3100 Avant Geneic Analyzer, Applied Biosystems, Foster City, CA). Isolate genptypes were compared with control isolates of known clonal lineage, including BBA9/95 (EU1), PrlO2 (NA1), and WSDA3765 (NA2). Three of four isolates belonged to genotype EU1. The fourth isolate, obtained from O. fragrans, belonged to genotype NA1. We repeated genotyping on independent genomic DNA extractions and obtained identical results. Two EU1 isolates and the single NA1 isolate were tested for mating type (1) and found to be of A1, A1, and A2 mating type, respectively. The coexistence of A1 and A2 mating types in the same retail nursery suggests the potential for sexual reproduction, as is the case in P. infestans where clonal and sexual populations exist (2), although to date, sexual reproduction in nature has not been documented in P. ramorum. The California retail nursery infestation highlights the risks associated with the unintentional transport of host nursery stock infested with P. ramorum.

It is also an introduced plant that is widely distributed in North America. In May of 2007, approximately 20 forked catchfly plants on the campus of Ondokuz Mayis University in Samsun, Turkey were found diseased with the anther smut fungus Microbotryum violaeeum (Pers.:pers.) G. Demi & Oberw. (Basidiomycota, Microbotryomycetes, Microbotryales [3], Microbotrya-ceae). All anthers in all flowers of diseased plants were smutted. Diseased flowers were collected, air dried, and sent to the quarantine facility of the Foreign Disease-Weed Science Research Unit (FDWSRU), USDA/ARS, Fort Detrick, MD. Teliospores within the flowers were extracted and observed microscopically. Teliospores were globose, 6 to 9 urn (mean 6.5 mu m) in diameter, pale violet, with reticulate walls, and matching the description of M. violaeeum (4). Nucleotide sequences for the internal transcribed spacers (ITS 1 and 2) and 5.8S ribosomal region (GenBank Accession No. EU122308) were aligned with other sequences in GenBank with the BLAST algorithm. Sequences of this isolate aligned 99% with sequences of other isolates of M. violaeeum, M. lychnidis-dioicae (A.P. de Candolle ex J.I. Liro) G. Demi & F. Oberwinkler, and M. silenes-inflatae (A.P. de Candolle ex J.I. Liro) G. Demi & F. Oberwinkler and clustered with other M. violaeeum isolates. M. violaeeum is an obligate parasite of many plant species in the Caryophyllaceae family, and the fungus has been widely studied as a model for population genetics and evolutionary biology (2). To our knowledge, this is the first report of M. violaeeum parasitizing forked catchfly in Turkey, and is the only report of this fungus-plant interaction in Asia Minor (1).

Two sets of primers corresponding to a portion of the replicase gene of LChV-1 and LChV-2 were used in one-tube reverse-transcription polymerase chain reactions to detect these viruses in total RNA extracts of field-collected sweet cherry tissues. LChV-1 and LChV-2 were detected both alone and in combination in five sweet cherry orchards in Washington State. Sequence analysis of a 240-nucleotide (nt) fragment of the replicase open reading frame (ORF)lb and a 232-nt fragment from a portion of ORF8 and the 3' untranslated region (UTR) of LChV-1 indicated that North American (NA) isolates shared 90 to 99% nucleotide identity in both genome segments analyzed. In contrast, comparisons of NA isolates to two Eurasian isolates of LChV-1 indicated shared nucleotide identities of 79 to 82% in the replicase fragment and 89 to 90% in the ORF8/3'UTR fragment. Sequence variation in the replicase region did not affect detection of LChV-1 in 12 isolates using the replicase-specific primers reported here. This article represents the first report of LChV-1 and LChV-2 in sweet cherry in Washington.

We show that the redbay mortality is due to a vascular wilt disease caused by an undescribed Raffaelea sp. that is a fungal symbiont of Xyleborus glabratus, an exotic ambrosia beetle. Trees affected by the disease exhibit wilt symptoms that include a black discoloration of the sapwood. Redbay trees and containerized seedlings died within 5 to 12 weeks after inoculation with the Raffaelea sp. When redbay seedlings were challenged with X. glabratus, the beetles tunneled into 96% of the plants, 70% died, and the Raffaelea sp. was recovered from 91%. X. glabratus and the Raffaelea sp. have also been associated with mortality of sassafras, and the Raffaelea sp. has been isolated from wilted pondberry and pondspice. Additional inoculation studies have shown that the Raffaelea sp. is pathogenic to sassafras, spicebush, and avocado, but not to red maple. Female adults of X. glabratus have paired mycangia near the mandibles, and the Raffaelea sp. is routinely isolated from the heads of beetles. The fungus is apparently introduced into healthy redbay during beetle attacks on stems and branches. The wilt currently affecting redbay and sassafras represents a major threat to other members of the Lauraceae indigenous to the Americas, including avocado in commercial production.

Stem internode and petiole tissues from infected and uninfected control plants of four grape genotypes (Vitis vinifera, V. rufotomentosa, V. smalliana, and V. arizonica/candicans) differing in PD susceptibility were examined using scanning electron microscopy (SEM). Tyloses, fibrillar networks, and gum plugs were observed in lumens of tracheary elements in petioles and internodes of both water-inoculated control plants and X. fastidiosa-inoculated plants of all genotypes. Bacteria were not observed in control plants. In both petiole and internode tissues, the greatest number of occluded xylem vessels were observed in V. vinifera and the smallest number in V. arizonica/candicans. The number of xylem vessels infested with X. fastidiosa was greatest in V. vinifera and did not differ among the other three genotypes. Systemic infection was found in all genotypes. The frequency with which X. fastidiosa infested vessels were observed using SEM corresponded well with bacterial levels estimated by enzyme-linked immunosorbent assay. Among infected plants, tylose formation in internodes was lowest in V. arizonica/candicans and did not differ among the other three genotypes. Infection with X. fastidiosa strongly induced tylose formation in V. vinifera and V. smalliana but not in V. arizonica/candicans. Analysis across tissues and genotypes indicated an induction of fibrillar networks and gum occlusions in response to X. fastidiosa infection, whereas treatment comparisons within genotypes were not significant except for V. vinifera petioles. Limiting the spread of X. fastidiosa infection by xylem conduit occlusions does not appear to be the mechanism conferring PD resistance or tolerance to V. arizonica/candicans, V. smalliana, or V. rufotomentosa. In contrast, the strong induction of tyloses may be detrimental rather than beneficial for V. vinifera survival after X. fastidiosa infection.

Previous investigators have isolated diverse bacteria from the lungs of affected sheep, but no single bacterial species is consistently present, even within single epizootics. We obtained high-quality diagnostic specimens from nine pneumonic bighorn sheep in three populations and analyzed the bacterial populations present in bronchoalveolar lavage specimens of seven by using a culture-independent method (16S rRNA gene amplification and clone library analyses). Mycoplasma ovipneumoniae was detected as a predominant member of the pneumonic lung flora in lambs with early lesions of bronchopneumonia. Specific PCR tests then revealed the consistent presence of M. ovipneumoniae in the lungs of pneumonic bighorn sheep in this study, and M. ovipneumoniae was isolated from lung specimens of five of the animals. Retrospective application of M. ovipneumoniae PCR to DNA extracted from archived formalin-fixed, paraffin-embedded lung tissues of historical adult bighorn sheep necropsy specimens supported the association of this agent with bronchopneumonia (16/34 pneumonic versus 0/17 nonpneumonic sheep were PCR positive [P < 0.001]). Similarly, a very strong association was observed between the presence of one or more M. ovipneumoniae antibody-positive animals and the occurrence of current or recent historical bronchopneumonia problems (seropositive animals detected in 9/9 versus 0/9 pneumonic and nonpneumonic populations, respectively [P < 0.001]). M. ovipneumoniae is strongly associated with bronchopneumonia in free-ranging bighorn sheep and is a candidate primary etiologic agent for this disease.

It has been demonstrated that simultaneous hydrolysis of WS to achieve 100% hydrolysis to simple sugars (to the extent achievable under present conditions) and fermentation to butanol is possible. In addition to WS, the reactor was fed with a sugar solution containing glucose, xylose, arabinose, galactose, and mannose. The culture utilized all of the above sugars. It was noticed that near the end of fermentation (286-533 h), the culture had difficulties utilizing xylose. As a result of supplemental sugar feed to the reactor, ABE productivity was improved by 16% as compared with previous studies. In our previous experiment on simultaneous saccharification of WS and fermentation to butanol, a productivity of 0.31 g L super(-1) h super(-1) was observed, while in the present studies a productivity of 0.36 g L super(-1) h super(-1) was observed. It should be noted that a productivity of 0.77 g L super(-1) h super(-1) was observed when the culture was highly active. The fed-batch fermentation was operated for 533 h. It should be noted that C. beijerinckii P260 can be used to produce butanol from WS in integrated fermentations.

Field studies were used to determine the effects of crop competitive ability on season-long herbicide performance in sweet corn. Two sethoxydim-tolerant sweet corn hybrids were grown in the presence of Panicum miliaceumand plots were treated post-emergence with a range of sethoxydim doses. Significant differences in height, leaf area index and intercepted light were observed between hybrids near anthesis. Across a range of sub-lethal herbicide doses, the denser canopy hybrid Rocker suppressed P. miliaceumshoot biomass and fecundity to a greater extent than the hybrid Cahill. Yield of sweet corn improved to the level of the weed-free control with increasing sethoxydim dose. The indirect effect of herbicide dose on crop yield, mediated through P. miliaceumbiomass reduction, was significant for all of the Cahill's yield traits but not Rocker. These results indicate that a less competitive hybrid requires relatively more weed suppression by the herbicide to not only reduce weed growth and seed production, but also to maintain yield.

Two insecticides with the same mode of action are used almost exclusively for SBRM control. Alternative control strategies would be required if insecticide-resistant SBRM developed or the insecticides were no longer available due to regulatory actions. Germplasm lines with SBRM resistance are available, but information on the SBRM resistance of hybrid cultivars created by crossing these lines with a SBRM-susceptible cms parental line is lacking. This study compared the performance of four hybrids with SBRM-resistant pollinators to two susceptible hybrids, with and without insecticide, in four environments. In all environments, the hybrids with the SBRM-resistant pollinators and no insecticide had root yields equal to the SBRM-susceptible commercial hybrid with insecticide. In two environments, the root yields of the SBRM-susceptible hybrids were low and the difference between the root yields with and without insecticide was relatively small, indicating the insecticide was ineffective. In contrast, the root yields of the SBRM-resistant hybrids, with or without insecticide, in these trials were substantially higher than the susceptible hybrids and similar to corresponding root yields at the other sites. Based upon these trials, it appears that hybrids produced with the currently available resistance sources would have sufficient SBRM resistance to prevent catastrophic yield reductions due to SBRM feeding, could reduce uncertainty caused by fluctuations in insecticide effectiveness, would provide protection against the development of insecticide-resistant SBRM strains, and also provide a useful level of SBRM protection, if the current insecticides were no longer available.

Aflatoxin contamination of food and feed is an age old problem of particular concern over the last four decades. Now, for the first time control measures for this problem appear within reach. For practical and sustainable control of aflatoxin contamination to be realised, however, additional information is needed rather rapidly, particularly for understanding the specific molecular factors (both in the plant and the fungus) involved during host plant-fungus interaction. The information derived from the use of novel tools such as genomics, proteomics and metabolomics provides us with the best and the quickest opportunity to achieve a clear understanding of the survival of toxigenic fungi in the field, the ability of the fungus to invade crops, and the process of toxin contamination under various environmental conditions. Significant progress has been made recently in understanding the genomic makeup of the most significant aflatoxin producing field fungus, namely Aspergillus flavus. Progress also has been made in the study of host crop resistance to fungal invasion through the use of proteomics. The information available on production of aflatoxin and other metabolites by Aspergillus flavus is reasonably extensive, although the application of metabolomics as a tool in this study is relatively new. In this review there is a discussion of the use of genomics, proteomics and metabolomics in deriving the requisite information for developing effective strategies to interrupt the machinery in the fungus for production of these toxins, as well as to assist in the development of host-resistance against fungal invasion and aflatoxin contamination of crops.

FHB epidemics have been on the increase since 1993 and have caused severe monetary damage for the growers and seed industry. Along with reduced yields, the presence of mycotoxins in moldy grain constitutes a major problem for the grain industry. These mycotoxins pose health hazards to humans and animals upon ingestion. The acute phytotoxicity of these mycotoxins and their occurrence in plant tissues correlates with their role in pathogenesis and the production of plant disease. Transgenic plants incorporating the Fusarium sporotrichioides Tri101 gene, a gene that reduces toxicity of trichothecenes, have reduced levels of disease, thus demonstrating that FHB severity and deoxynivalenol (DON) accumulation can be reduced in small grains by the introduction of a toxin-modification gene.

Statistically-based inventory efforts that started in Scandinavian countries in the 1920s raised interest in developing a similar program in the U.S. The U.S. Congress established the research branch of the U.S. Forest Service in 1928, shortly after Dr. Yrjoe Ilvessalo, leader of the first Finnish national forest inventory, met with President Calvin Coolidge. Congress charged the Forest Service to find "facts as may be necessary in the determination of ways and means to balance the timber budget of the United States". As a result, Forest Survey maintained a timber focus for much its history. As society's interest in forests changed over time, so did information needs. Conflicts over resource allocation and use could not be resolved without up-to-date knowledge of forest status and trends. In response to society's needs, the Forest Inventory and Analysis program has evolved from Forest Survey to address diverse topics such as forest health, carbon storage, wildlife habitat, air pollution, and invasive plants, while continuing its mandate to monitor the Nation's timber supply. The Forest Inventory and Analysis program collects data on all land ownerships on an annual basis. The data are used to develop reports on a regular basis; reports and raw data are available to the public at no cost. The data are also used by scientists in a growing number of applications. A short history of the Forest Survey is presented with several examples of current research based on Forest Inventory and Analysis data.

During germination, both minerals and phosphate are released upon phytase-catalyzed degradation of PA. We generated a soybean line (CAPPA) in which an Escherichia coli periplasmic phytase, the product of the appA gene, was expressed in the cytoplasm of developing cotyledons. CAPPA exhibited high levels of phytase expression, greater than or equal to 90% reduction in seed PA, and concomitant increases in total free phosphate. These traits were stable, and, although resulted in a trend for reduced emergence and a statistically significant reduction in germination rates, had no effect on the number of seeds per plant or seed weight. Because phytate is not digested by monogastric animals, untreated soymeal does not provide monogastrics with sufficient phosphorus and minerals, and PA in the waste stream leads to phosphorus runoff. The expression of a cytoplasmic phytase in the CAPPA line therefore improves phosphorus availability and surpasses gains achieved by other reported transgenic and mutational strategies by combining in seeds both high phytase expression and significant increases in available phosphorus. Thus, in addition to its value as a high-phosphate meal source, soymeal from CAPPA could be used to convert PA of admixed meals, such as cornmeal, directly to utilizable inorganic phosphorus.

Three USDA Natural Resource Conservation Service-designed sinkhole filters for removing contaminants from manure-impacted infiltrating water were assessed for removal efficiency of indicator bacteria and nitrate. Geometric mean fecal coliform bacteria concentrations decreased 85% to 96%. Mean nitrate concentrations increased 130% at two of the filter locations. The sinkhole filters probably filtered out sediment and associated contaminants, such as fecal coliform bacteria, but had no filtering effect on solutes like nitrate. Nitrate concentrations might have increased because of nitrification in the filter media between runoff events. The sinkhole filter appears to be an effective management tool in order to reduce inputs of pathogens to karst groundwater aquifers.

Yet rural and urban developments increasingly are impacting the vitality of riparian areas by changing land use, diverting water, and lowering the water table. The San Pedro River in southeastern Arizona is a good example of such a situation. Population growth and the resulting increase in groundwater pumping in the Upper San Pedro Basin have created concern that the water table may fall below the rooting zone of the riparian vegetation, leading to abrupt changes in many ecosystems. A multidisciplinary group of government scientists and university researchers has been working to better understand the hydrological functioning of riparian systems in the Southwest, particularly the quantification of riparian evapotranspiration (ET). Groundwater modeling studies have long shown that water use by riparian vegetation is an important component of the basin water balance.

In this work, we developed a new set of analytical solutions for the concentration ensemble mean, variance, and coefficient of variation (CV), which consider the effects of all these factors. We developed these models as generalizations of the first-order solutions in the log-conductivity variance of point concentration proposed by [Fiori A, Dagan G. Concentration fluctuations in aquifer transport: a rigorous first-order solution and applications. J Contam Hydrol 2000; 45(1-2):139-163]. Our first-order solutions compare well with numerical simulations for small and moderate formation heterogeneity and from small to large sampling and source volumes. However, their performance deteriorates for highly heterogeneous formations. Successively, we used our models to study the interplay among sampler size, source volume, and PSD. Our analysis shows a complex and important interaction among these factors. Additionally, we show that the relative importance of these factors is also a function of plume age, of aquifer heterogeneity, and of the measurement location with respect to the mean plume center of gravity. We found that the concentration moments are chiefly controlled by the sampling volume with pore-scale dispersion playing a minor role at short times and for small source volumes. However, the effect of the source volume cannot be neglected when it is larger than the sampling volume. A different behavior occurs for long periods, which may be relevant for old contaminations, or for small injection volumes. In these cases, PSD causes a significant dilution, which is reflected in the concentration statistics. Additionally, at the center of the mean plume, where high concentrations are most likely to occur, we found that sampling volume and PSD are attenuating mechanisms for both concentration ensemble mean and coefficient of variation, except at very large source and sampler sizes, where the coefficient of variation increases with sampler size and PSD. Formation heterogeneity causes a faster reduction of the ensemble mean concentrations and a larger uncertainty at the center of the mean plume. Therefore, our results highlight the importance of considering the combined effect of formation heterogeneity, exposure volume, PSD, source size, and measurement location in performing risk assessment.

The difference in mean annual precipitation between multiyear dry and wet periods was 33% of the long-term mean and led to a corresponding 100% change in mean reservoir inflow, 170% change in mean annual flood releases from the reservoir, and a maximum drop in conservation pool elevation of 2 m. From a reservoir operations perspective, only the frequency of controlled flood releases was impacted by decadal precipitation variations. These flood releases were sporadic in nature, and the more frequent releases during wet periods were not believed to appreciably enhance stream habitat and riparian vegetation downstream of the reservoir. It was further reasoned that large differences in annual reservoir inflow due to decadal precipitation variations would likely be accompanied by related changes in upstream soil erosion and reservoir sediment loading. With regard to hydrologic and environmental modeling, it was argued that decadal precipitation variations had important implications for model calibration, verification, and subsequent application. Overall, this case study demonstrated watershed and reservoir hydrology were sensitive to decadal precipitation variations and suggested that decadal precipitation variations deserved careful consideration in hydrologic and water quality investigations in central Oklahoma.

However, previous research has shown that TEOM samplers may not report accurate PM concentrations due to the operating characteristics of the automated system. This article presents the results of a multiyear study using collocated TEOM and gravimetric samplers configured to measure TSP concentrations from a Texas cattle feedlot. The objective of this work was to define the relationship between PM concentrations measured by TEOM and gravimetric samplers and characterize the influence of concentration intensity and particle size on that relationship. The results show that there was a significant positive linear relationship between the concentrations measured by the TEOM and gravimetric TSP samplers (p-values < 0.001). It was observed that in general, the TEOM samplers reported lower TSP concentrations than the collocated gravimetric TSP sampler. Further investigation into these results indicated that the difference in the concentration measured by the TEOM sampler versus the gravimetric TSP sampler (known as the TEOM measurement error) is correlated with the concentration measured by the gravimetric TSP sampler, but the nature of that relationship varies by location. However, linear relationships were observed between the measurement error of the TEOM samplers and the mass median diameter and geometric standard deviation of the collocated gravimetric TSP sample.

A greenhouse trial was established to determine differences in spray retention in a poinsettia canopy between single-nozzle, handgun applications made using three different spray volumes and three different spray qualities. For the same areas of the canopy, there were few differences in spray deposit between treatments. Canopy position was a significant factor in the amount of spray found on foliar and artificial targets. Higher deposits were measured in the fronts and upper areas of the canopy than the backs and lower areas of the canopy. There were no significant differences in recovery of fungicide from leaves between treatments. The high-volume application produced the highest deposits on artificial targets across all spray qualities. There were no significant differences in overall spray deposit between the low- and medium-volume treatments.

The power of this approach is that it enables a direct comparison of M. avium subsp. paratuberculosis proteins to each other in relation to their immunostimulatory capabilities. In this study, 93 recombinant proteins, produced in Escherichia coli, were arrayed and spotted onto nitrocellulose. These proteins include unknown hypothetical proteins and cell surface proteins as well as proteins encoded by large sequence polymorphisms present uniquely in M. avium subsp. paratuberculosis. Also included were previously reported or known M. avium subsp. paratuberculosis antigens to serve as a frame of reference. Sera from healthy control cattle (n = 3) and cattle infected with either M. avium subsp. avium and Mycobacterium bovis were exposed to the array to identify nonspecific or cross-reactive epitopes. These data demonstrated a degree of cross-reactivity with the M. avium subsp. avium proteins that was higher than the degree of cross-reactivity with the more distantly related M. bovis proteins. Finally, sera from naturally infected cattle (n = 3) as well as cattle experimentally infected with M. avium subsp. paratuberculosis (n = 3) were used to probe the array to identify antigens in the context of Johne's disease. Three membrane proteins were the most strongly detected in all serum samples, and they included an invasion protein, an ABC peptide transport permease, and a putative GTPase protein. This powerful combination of genomic information, molecular tools, and immunological assays has enabled the identification of previously unknown antigens of M. avium subsp. paratuberculosis.

The spatiotemporal distribution of Escherichia coli 15597 along the water system was employed to locate pollutants by inversely interpreting transport patterns of E. coli using ANNs. Results showed that dispersion patterns of E. coli were positively correlated to pH, turbidity, and conductivity (R super(2)=0.90-0.96), and the ANN models successfully identified the source location of E. coli introduced into a given system with 75% accuracy based on the pre-programmed relationships between E. coli transport patterns and release locations. The findings in this study will enable us to assess the vulnerability of essential water systems, establish the early warning system and protect humans and the environment.

Using this technique, 8564 bp of new DNA sequences were obtained from three genomic loci; tufB-secE-nusG-rplKAJL-rpoBC gene cluster, omp gene (outer membrane protein, Omp) and 16/23S rRNA gene in Ca. L. asiaticus. These, together with publicly available Ca. Liberibacter sequences, are clustered into five contigs and two singlets representing 24,477 non- redundant base pairs. BLAST annotation predicts 12 full-length genes, two partial genes and one pseudogene among these sequences. The sequences obtained in this study provide new genome information about Ca. Liberibacter that will facilitate development of new genome-based detection tools. The technique described here can also be employed to acquire new genomic information for other unculturable or fastidious organisms for which available sequences are limited or for filling sequence gaps between known flanking genomic DNA sequences.

B. anthracis Sterne was weakly inactivated (-0.003 to -0.014 log sub(10) CFU/h) at storage temperatures of 2 to 16 degree C and at temperatures greater than and equal to 45 degree C. Growth was observed from 17 to 44 degree C. At these intermediate temperatures, B. anthracis Sterne displayed growth patterns with lag, growth, and stationary phases. The lag phase duration decreased with increasing temperature and ranged from approximately 3 to 53 h. The growth rate increased with increasing temperature from 0.011 to 0.496 log sub(10) CFU/h. Maximum population densities (MPDs) ranged from 5.9 to 7.9 log sub(10) CFU/g. In addition, the fate of B. anthracis Ames K0610 was measured at 10, 15, 25, 30, 35, 40, and 70 degree C to compare its behavior with that of Sterne. There were no significant differences between the Ames and Sterne strains for both growth rate and lag time. However, the Ames strain displayed an MPD that was 1.0 to 1.6 times higher than that of the Sterne strain at 30, 35, and 40 degree C. Ames K0610 spores were rapidly inactivated at temperatures greater than or equal to 45 degree C. The inability of B. anthracis to grow between 2 and 16 degree C, a relatively low growth rate, and inactivation at elevated temperatures would likely reduce the risk for recommended ground-beef handling and preparation procedures.

DNA extracted from feces or rectal swabs was amplified by polymerase chain reaction using parasite-specific small subunit ribosomal RNA gene primers. All positive specimens were subjected to gene sequence analysis. Of 83 dolphins, 17 were positive for Microsporidia. None was positive for Cryptosporidium or Giardia. Gene sequence data for each of the positive specimens were compared with data in GenBank. Fourteen specimens were found similar to, but not identical to, the microsporidian species Kabatana takedai, Tetramicra brevifilum, and Microgemma tinca, reported from fish, and possibly represent parasites of fish eaten by dolphins. Gene sequence data from 3 other specimens had 687% similarity to Enterocytozoon bieneusi, a species known primarily to infect humans and a variety of terrestrial mammals, including livestock, companion animals, and wildlife. It is not clear if these specimens represent a species from a terrestrial source or a closely related species unique to dolphins. There were neither clinical signs nor age- or gender-related patterns apparent with the presence of these organisms.

Most countries have adopted regulations that limit the quantity of aflatoxins in food and feed to 20 µg kg-1 or less; however, environmental conditions in most of the world where peanuts are produced and stored often make it difficult or impossible to attain such low concentrations. In addition to aflatoxins, peanuts are often contaminated with cyclopiazonic acid (CPA). Both mycotoxins are produced by Aspergillus flavus, a ubiquitous fungus that can infect and grow in peanuts under both pre- and post-harvest conditions. Management of mycotoxin contamination in peanuts generally involves removal of high-risk components from shelled lots or the removal of individual, highly contaminated nuts. This is accomplished by various processes such as screening, kernel sizing, electronic colour sorting, hand sorting, and blanching followed by electronic colour sorting. Recently, biological control technology has been developed that prevents much of the contamination that might otherwise occur. Biocontrol is based on competitive exclusion whereby a dominant population of a non-toxigenic strain of A. flavus is established in the soil before peanuts are subjected to conditions favouring contamination. The applied strain competes with toxigenic strains for infection sites, resulting in significantly reduced concentrations of aflatoxins in peanuts. Monitoring of the first commercial use of the technology showed that aflatoxins were reduced by an average of 85% in farmers' stock peanuts and by as much as 98% in shelled, edible grade peanuts.

Real-time PCR also was developed with detection limits estimated to be between 10 super(-4) and 1 super(-4) ng by serial dilution of a recombinant S. citri plasmid into DNA extracts from healthy Madam Vinous sweet orange. PCR for the detection of S. citri by these new primers was validated by comparing culturing of the pathogen, the traditional method of diagnosis, with PCR assays from samples taken from two citrus plots in Kern County, CA. Fruit columella was collected from 384 and 377 individual trees in each of two fields, respectively, one portion was used for culturing and the other for DNA extraction and PCR. PCR results matched those of culturing 85 to 100% of the time depending on the primers used. More importantly, PCR detected S. citri from culture-negative trees in 5 to 15% of the cases, suggesting that PCR performed as well or better than culturing for detection of S. citri in field samples. Realtime PCR proved to be the best method for detection. Differential reaction of the samples to the P58 primer pairs suggested that two populations of S. citri occur in historical and present-day field isolates. Citrus stubborn disease incidence was estimated to be 58.3 and 3.7% in the two orchards. The results presented here support the use of PCR for reliable detection of S. citri in field trees.

In immunoblotting analysis, MAbCPV40-1 bound to a 40-kDa protein in extracts of C. parvum oocysts. This 40-kDa protein was localized in the sporozoite cytoplasm by immunofluorescence (IFA) staining with MAbCPV40-1. In a dot-blot assay, MAbCPV40-1 was capable of detecting 102 non-bleach-treated and 102-103 bleach-treated C. parvum oocysts. MAbCPV40-1 was capable of detecting CPV40 antigen in both soluble and total C. parvum oocyst protein extracts, indicating a potential use for detecting this parasite in environmental samples.

A two-stage treatment of aspen wood particles with solutions of carboxymethyl cellulose (CMC) and ferrous chloride afforded a biosorbent that was effective in removing phosphate from test solutions. FTIR spectroscopy of the biosorbent samples showed a decrease in the intensity of the carboxylate signal coinciding with a decrease in particle size. Elemental analysis results showed the iron content of both the biosorbent samples, and wood particles treated with ferrous chloride alone, to also decrease with particle size. The relationship between iron content and particle size for the biosorbent samples appeared to be a function of both the amount of CMC-Fe complex and the efficiency of removing free iron ions after treating. Sorption testing results showed a strong linear correlation between the phosphorous uptake capacities and the iron contents of the samples adjusted for losses of iron during testing. As anticipated, pretreating with the anionic polymer provided additional sites to complex iron and thereby imparted a greater phosphorous uptake capacity. Although the larger wood particles provided a greater amount of iron for phosphate removal, smaller wood particles may be preferred since they afforded the lowest release of iron relative to the amount of phosphate removed.

Two molecular methods, inter-simple sequence repeat-polymerase chain reaction DNA fingerprinting and a phylogeographic approach inferred from the mitochondrial cytochrome oxidase subunit I gene (COI), were utilized. Five geographic populations from South America were analyzed; in addition, a phylogenetic analysis was performed with several named and one unnamed Gonatocerus species using the COI gene. DNA fingerprinting demonstrated a fixed geographic banding pattern difference in the population from San Rafael, Mendoza Province, Argentina. The COI analysis uncovered haplotype or geographic structure in G. tuberculifemur. A neighbour-joining distance (NJ) and a single most parsimonious tree (MP) clustered the populations into two well-supported distinct clades with strong bootstrap values (97-99% and 92-99%, respectively) with populations from San Rafael clustering into clade 2 and the rest of the populations clustering into clade 1. No haplotype sharing was observed between individuals from the two clades. Phylogenetic analyses performed by NJ and MP methods with 15 Gonatocerus species confirmed species boundaries and again uncovered two distinct clades in G. tuberculifemur with strong bootstrap support (95-100% and 68-100%, respectively). However, the NJ tree supported the morphologically defined relationships better than the MP tree. The molecular evidence in the present study is suggestive of a species level divergence. Because G. tuberculifemur is under consideration as a potential biological control agent for GWSS in California, understanding cryptic variation in this species is critical.

Maize (Zea mays L.), spring wheat (Triticum aestivum L.), and grain sorghum (Sorghum bicolor L.) were included as controls for a total of 30 species. Twenty pots of each species were planted in a randomized complete block design. Each pot was infested 5 wk later with 20 neonate northern corn rootworm larvae. Two pots within each species and block were assigned an extraction date of 7 or 14 d after infestation. The remaining two pots from each block were used to monitor adult emergence. The percentage of larvae recovered, change in larval head capsule width, and change in average dry weights varied significantly among the grass species. The highest percentage of larvae was recovered from slender wheatgrass, Elymus trachycaulus (Link), and this was significantly greater than the percentage recovered from all other species including maize for the 14-d sample date. Several additional species were also relatively good hosts, in that the percentage of larvae recovered from these species was not significantly different from maize. The average dry weight of larvae recovered was significantly greater for larvae recovered from maize than for larvae recovered from all other species except slender wheatgrass, when the two samples dates were combined. Overall, adults were produced from only 6 of the 28 species evaluated, and no analysis was performed because of the low numbers. The results of this study are discussed in relation to the potential of alternate hosts of northern corn rootworm to serve as a bridge to survival on transgenic maize.

The entomopathogenic fungus Beauveria bassiana (Balsamo) Vuillemin is pathogenic to C. caryae. One approach to managing C. caryae may be application of B. bassiana directed toward adult weevils as they emerge from the soil to attack nuts in the tree canopy. Our objective was to compare different application methods for suppression of C. caryae adults. Treatments included direct application of B. bassiana (GHA strain) to soil under the tree canopy, soil application followed by cultivation, soil application in conjunction with a cover crop (Sudan grass), direct application to the tree trunk, and application to the trunk with an UV radiation-protecting adjuvant. The study was conducted in a pecan orchard in Byron, GA, in 2005 and 2006. Naturally emerging C. caryae adults, caught after crawling to the trunk, were transported to the laboratory to determine percentage mortality and signs of mycosis. When averaged over the 15-d sampling period, weevil mortality and signs of mycosis were greater in all treatments than in the nontreated control in 2005 and 2006; >75% average mortality was observed with the trunk application both years and in the trunk application with UV protection in 2005. Results indicated trunk applications can produce superior efficacy relative to ground application, particularly if the ground application is followed by cultivation. Efficacy in the cover crop treatment, however, did not differ from other application approaches. Future research should focus on elucidating the causes for treatment differences we observed and the extent to which B. bassiana-induced C. caryae mortality reduces crop damage.

This environment, along with the fact that larvae possess a high rate of water loss and are extremely tolerant of desiccation, may promote the use of cryoprotective dehydration as a strategy for winter survival. This study investigates the capacity of larvae to resist inoculative freezing and undergo cryoprotective dehydration at subzero temperatures. Slow cooling to -3 degree C in an environment at equilibrium with the vapor pressure of ice reduced larval water content by similar to 40% and depressed the body fluid melting point more than threefold to -2.6 degree C. This melting point depression was the result of the concentration of existing solutes (i.e. loss of body water) and the de novo synthesis of osmolytes. By day 14 of the subzero exposure, larval survival was still >95%, suggesting larvae have the capacity to undergo cryoprotective dehydration. However, under natural conditions the use of cryoprotective dehydration may be constrained by inoculative freezing as result of the insect's intimate contact with environmental ice. During slow cooling within a substrate of frozen soil, the ability of larvae to resist inoculative freezing and undergo cryoprotective dehydration was dependent upon the moisture content of the soil. As detected by a reduction of larval water content, the percentage of larvae that resisted inoculative freezing increased with decreasing soil moisture. These results suggest that larvae of the Antarctic midge have the capacity to resist inoculative freezing at relatively low soil moisture contents and likely undergo cryoprotective dehydration when exposed to subzero temperatures during the polar winter.

However, for community types to succeed as proxies for species abundance, several assumptions must be met. We tested these assumptions for birds in an Oregon forest environment. Measured habitat was a weak proxy for species abundance and vegetation cover type was a weak proxy for habitat, explaining only 4% of the variance in species abundance. The adequacy of forest community types as habitat proxies was highly dependent on classification rules and the spatial scales at which communities were defined. Habitat was perceived differently by species guilds and a single, generalized characterization of habitat is therefore unlikely to provide a reliable basis for multi-species conservation efforts. Given the weak relations between forest vegetation and species abundance, evaluation of landscape pattern is unlikely to be an effective replacement for the direct monitoring of species population size and distribution.

Although cover pole dimensions, measurement criteria, and interpretation of cover pole data vary depending on measurement objectives, the technical use of cover poles is fairly consistent. Practical use of cover poles requires that they are sturdy, lightweight, and easily transported. We describe a cover pole apparatus that can be easily constructed, transported, and assembled for use in remote locations. This self-supporting cover pole enables one person to take measurements, and can be modified for use in multiple habitats and soil types.

Africanastrongylus buceros gen. nov. et sp. nov. is characterized by a symmetrical tapering synlophe in the cervical region and a maximum of 60 ridges in males and females. Bursal structure is 2-2-1, with subequal Rays 4/5, massive Rays 8, and Rays 9/10, and a massive dorsal lobe that is reduced in length, laterally and dorsally inflated, and positioned ventral to externodorsal rays. Spicules are tripartite, and the gubernaculum is broadly alate in the anterior. A proconus is present. Among ostertagiines with a 2-2-1 bursa (Cervicaprastrongylus, Hyostrongylus, Mazamastrongylus, Sarwaria, Spiculopteragia, and Teladorsagia) specimens of Africanastrongylus are differentiated from respective genera based on the structure of the cervical synlophe, patterns of dorsal, externodorsal, lateral, and ventral rays, and configuration of the genital cone, gubernaculum, and spicules. Among 13 genera of the Ostertagiinae in the global fauna, 3 are entirely limited in distribution to Africa, including Africanastrongylus, Longistrongylus, and Pseudomarshallagia. Another 5 genera including Cervicaprastrongylus, Hyostrongylus, Marshallagia, Ostertagia, and Teladorsagia are represented as mosaics, with diversity centered in Eurasia or the Holarctic. Genera not represented in the African fauna include Camelostrongylus among Caprinae and some Antelopinae from Eurasia, Mazamastrongylus and Spiculopteragia in Cervidae from the Holarctic and Eurasia, respectively, Orloffia in Cervidae and Bovidae from the Holarctic, and Sarwaria among Tragulidae and Bovinae in southern Asia. The diverse nature of the ostertagiine fauna, with a disproportionate number of endemic genera relative to other regions of the northern hemisphere, may reflect the timing of episodic expansion events for artiodactyls into Africa from Eurasia during the Tertiary and Quaternary.

Effects of soil disturbance on surface runoff loss of chlorimuron and alachlor were evaluated utilizing runoff trays. Soil in the trays was either disturbed (tilled) and kept bare or was not tilled, and existing decomposed plant residue was left on the surface. Rainfall (25mm, 20min) was simulated 1d after alachlor (2.8kgha super(-) super(1)) or chlorimuron (54gha super(-) super(1)) application, and runoff was collected. Runoff fractions were analyzed for herbicide and sediment. Total alachlor loss from bare plots was greater than that in no-tillage plots (4.5% vs. 2.3%, respectively). More than one-third of total alachlor lost from bare plots occurred in the first l of runoff, while no-tillage plots had less runoff volume with a more even distribution of alachlor concentration in the runoff during the rainfall simulation and subsequent runoff period. In contrast, more chlorimuron was lost from no-tillage plots than bare plots (12% vs. 1.5%) even though total runoff volume was lower in the no-tillage plots (10.6mm vs. 13.6mm). This was attributed to dense coverage with partially decomposed plant residue in no-tillage plots (1652kgha super(-) super(1)) that intercepted chlorimuron. It was likely that chlorimuron, a polar compound, was more easily washed off surface plant residues and transported in runoff.

Recently, opal ''biospeleothems'' have been found in the World's largest cave in Precambrian sandstones on the Chimanta Tepui in Venezuela. The speleothems, although reminiscent of normal stalactites and stalagmites from limestone caves, are in fact large microbialites. More than a dozen forms were distinguished, but they share a common structure and origin. They consist of two main types: 1. fine-laminated columnar stromatolite formed by silicified filamentous microbes (either heterotrophic filamentous bacteria or cyanobacteria) and 2. a porous peloidal stromatolite formed by Nostoc-type cyanobacteria. The first type usually forms the central part and the second type, the outer part, of speleothems. Fungal hyphae, metazoan and plant remains also subordinately contribute to speleothem construction. The speleothems occur out of the reach of flowing water; the main source of silica is the condensed cave moisture which is the main dissolution-reprecipitation agent. Speleothems which originated by encrustation of spider threads are unique.

AN - 70309883; 18284158 AB - The environmental loading of steroid hormones contained in dairy wastes may cause an adverse effect on aquatic species. To better assess the potential risks of hormone contamination resulting from land application of dairy wastes, various steroid hormones were determined in a typical dairy waste disposal system. Quantitative methods using gas chromatography/mass spectrometry (GC/MS) were developed to monitor low levels of steroid hormones in complex solid and liquid samples contaminated with dairy manure. The preparation method for wastewater analysis consisted of solid-phase extraction and purification steps, which minimized interference from the sample matrices and achieved low detection limits for the studied hormones. In the dairy wastewater and lagoon water, three endogenous hormones-17alpha-estradiol, 17beta-estradiol, and estrone-were detected. The concentration of 17alpha-estradiol in fresh milk parlor effluent rapidly decreased along the wastewater disposal route, whereas the concentration of estrone increased along this same pathway. This suggests that 17alpha-estradiol was readily oxidized to the metabolite estrone. Levels of total steroid hormones in the sequencing lagoon water were approximately 1-3 orders of magnitude lower than those in the fresh dairy wastewaters, indicating significant removal of these hormones during the transport of dairy wastewater from source to field. In solid dairy waste samples, four steroid hormones were identified and quantified. Increasing the piling time of solid wastes and increasing the residence time of wastewater in sequencing lagoons are suggested to be economical and efficient agriculture practices to extend the degradation time of hormone contaminants and thereby reduce the hormone load to the environment.

SPOT reflectance observations were atmospherically corrected using aerosol data from MODIS and profiles of air temperature, humidity and ozone from the Atmospheric Infrared Sounder (AIRS), and used as input for the inversion of a canopy reflectance model. Computationally efficient inversion schemes were developed for the retrieval of soil and land cover-specific parameters which were used to build multiple species and site dependent formulations relating the two biophysical properties of interest to vegetation indices or single spectral band reflectances. Subsequently, the family of model generated relationships, each a function of soil background and canopy characteristics, was employed for a fast pixel-wise mapping of C sub(a) sub(b) and LAI. The biophysical parameter retrieval scheme is completely automated and image-based and solves for the soil background reflectance signal, leaf mesophyll structure, specific dry matter content, Markov clumping characteristics, C sub(a) sub(b) and LAI without utilizing calibration measurements. Despite the high vulnerability of near-infrared reflectances ( rho sub(n) sub(i) sub(r)) to variations in background properties, an efficient correction for background influences and a strong sensitivity of rho sub(n) sub(i) sub(r) to LAI, caused LAI- rho sub(n) sub(i) sub(r) relationships to be very useful and preferable over LAI-NDVI relationships for LAI prediction when LAI>2. Reflectances in the green waveband ( rho sub(g) sub(r) sub(e) sub(e) sub(n)) were chosen for producing maps of C sub(a) sub(b). The application of LAI-NDVI, LAI- rho sub(n) sub(i) sub(r) and C sub(a) sub(b)- rho sub(g) sub(r) sub(e) sub(e) sub(n) relationships provided reliable quantitative estimates of C sub(a) sub(b) and LAI for agricultural crops characterized by contrasting architectures and leaf biochemical constituents with overall root mean square deviations between estimates and in-situ measurements of 0.74 for LAI and 5.0 mu g cm super(-) super(2) for C sub(a) sub(b). The results of this study illustrate the non-uniqueness of spectral reflectance relationships and the potential of physically-based inverse and forward canopy reflectance modeling techniques for a reasonably fast and accurate retrieval of key biophysical parameters at regional scales.

AN - 70100207; 17904607 AB - E(rns) glycoprotein, along with E(1) and E(2), is one of the three envelope glycoproteins of classical swine fever virus (CSFV). E(rns) is a heavily glycosylated protein involved in several functions, including virus attachment and entry to target cells, production of neutralizing antibodies, and virulence. The role of added glycans to CSFV strain Brescia E(rns) on virus virulence was assessed in swine. A panel of virus mutants was constructed and used to investigate whether the removal of each of seven putative glycosylation sites in the E(rns) glycoprotein would affect viral virulence in swine. Only N269A/Q substitution rendered attenuated viruses (N1v/N1Qv) that, unlike BICv and other mutants, produced a transient infection in swine characterized by mild symptoms and decreased virus shedding. Notably, N1v efficiently protected swine from challenge with virulent BICv at 3 and 21 days post-infection suggesting that glycosylation of E(rns) could be modified for development of CSF live-attenuated vaccines.

Solutions of tannic acid, or other phenolic compounds, were added to soil samples to determine if they would affect recovery of soluble soil carbon (WSC) or -nitrogen (WSN) or influence the extraction and composition of Bradford-reactive soil protein (BRSP), associated with glomalin. Tannic acid-C added with water was not completely recovered from samples and the amount of total net WSC and WSN recovered was reduced, suggesting formation of insoluble complexes. By comparison, non-tannin phenolics like gallic acid, or methyl gallate, had little effect on extraction of WSC or WSN while a simple gallotannin derived from tannic acid, 1,2,3,4,6-penta-O-galloyl-d-glucose (PGG), inhibited extraction most. The C and N concentrations in BRSP increased when soil samples were treated with tannic acid or PGG before extraction, a procedure that includes autoclaving. Increases were greatest in the 10-20 cm compared to 0-5 cm depth. Accompanying these were declines in the ratio of absorbance at 465 and 665 nm (E4/E6 ratio) of BRSP extracts suggesting formation of larger or heavier molecules. In contrast, C and N composition in lyophilized BRSP was unaffected or even slightly reduced when tannic acid or PGG were added to the BRSP extract solution after the extraction process. We conclude that some tannins can reduce the solubility of labile soil C and N, at least temporarily and given unpredictability of response associated with phenolic substances, the Bradford assay should not be relied on to quantify pools or composition of soil proteins like glomalin.

Three antioxidants (BHT, two different alkylated diphenyl amines) were used in either 0.5 or 1.0 wt/wt%, in different ratios, and in conjunction with one another (hindered phenol/alkylated diphenyl amines or hindered phenol/mixed alkylated diphenyl amines). The estolide-based samples analyzed for their resistance to oxidation were two pure (distilled) estolides (oleic estolide 2-EH esters and coco-oleic estolide 2-EH esters), an estolide mixture that was analyzed straight from the reaction (coco-oleic estolide 2-EH esters with coco 2-EH esters) and finally the ester fraction from the estolide mixture (coco 2-EH esters). The coco estolide mixture and coco 2-EH esters had the best overall RPVOT times with 1.0% of the alkylated diphenyl amine, coco estolide mixture, 326 min, and coco 2-EH esters, 310 min. Coco estolides were expected to have an advantage over the simple oleic estolides due to the increase in saturation in the estolide. Unexpectedly, the two distilled estolides (oleic and coco) had very similar RPVOT max times with all the antioxidants, and were much higher than the other oxidative packages tested to date. In general, the alkylated diphenyl amine outperformed mixed alkylated diphenyl amines in the majority of the individual samples tested specially the coco 2-EH esters and distilled coco-oleic estolide 2-EH esters material at 1% OSP. Overall, a series of new antioxidants were tested and compared to other commercial products. A variety of physical properties of the four estolide based material were collected and compared to commercially acceptable material. Coco-oleic estolide 2-EH esters were formulated to have excellent pour points (-36 °C), were both oxidatively and hydrolytically stable (RPVOT, 310 min), with expected good biodegradability which should help commercialization.

Standard methods for automated image classification, however, limit classification detail in complex tropical landscapes. In this study, we test an approach to Landsat image interpretation on four islands of the Lesser Antilles, including Grenada and St. Kitts, Nevis and St. Eustatius, testing a more detailed classification than earlier work in the latter three islands. Secondly, we estimate the extents of land cover and protected forest by formation for five islands and ask how land cover has changed over the second half of the 20 super(th) century. The image interpretation approach combines image mosaics and ancillary geographic data, classifying the resulting set of raster data with decision tree software. Cloud-free image mosaics for one or two seasons were created by applying regression tree normalization to scene dates that could fill cloudy areas in a base scene. Such mosaics are also known as cloud-filled, cloud-minimized or cloud-cleared imagery, mosaics, or composites. The approach accurately distinguished several classes that more standard methods would confuse; the seamless mosaics aided reference data collection; and the multiseason imagery allowed us to separate drought deciduous forests and woodlands from semi-deciduous ones. Cultivated land areas declined 60 to 100 percent from about 1945 to 2000 on several islands. Meanwhile, forest cover has increased 50 to 950%. This trend will likely continue where sugar cane cultivation has dominated. Like the island of Puerto Rico, most higher-elevation forest formations are protected in formal or informal reserves. Also similarly, lowland forests, which are drier forest types on these islands, are not well represented in reserves. Former cultivated lands in lowland areas could provide lands for new reserves of drier forest types. The land-use history of these islands may provide insight for planners in countries currently considering lowland forest clearing for agriculture.

Growth rates were compared with tree densities ranging from 278 to 2,500 trees per hectare and tree dbh's (trunk diameters outside bark at breast height, 1.4 meters above ground on the upper side) from 10 to 40 cm. With angular spacing tree growth was found related to that of six equidistant adjacent trees. Frequent past remeasurements exposed tree growth trends with changes in the density of surrounding trees. Regressions of tree diameter growth based on relative basal area tree density had coefficients of determination (R super(2)) of 0.76 and 0.77 for clay and sand, respectively. As a guide to tree planting spacing and thinning for any plantation productivity goal a table is presented showing predicted time requirements to grow each 10 cm in dbh, mean annual dbh growth rates, and approximate periodic productivity of usable wood in m super(3)/ha/yr. On comparable sites this table permits managers of plantations with any spacing and mean tree dbh to predict current growth, number of years to any mature tree size, the approximate yield at that time, and tree growth stimulation after thinning of different intensities at different times.

Consequently, the development of new outlets for DDGS has become crucial to maintaining the economic viability of the industry. In light of these developments, this preliminary study aimed to determine the suitability of DDGS for use as a biofiller in low-cost composites that could be produced by rapid prototyping applications. The effects of DDGS content, particle size, curing temperature, and compression on resulting properties, such as flexural strength, modulus of elasticity, water activity, and color were evaluated for two adhesive bases. The composites formed with phenolic resin glue were found to be greatly superior to glue in terms of mechanical strength and durability: resin-based composites had maximum fiber stresses of 150-380kPa, while glue composites had values between 6kPa and 35kPa; additionally, glue composites experienced relatively rapid microbial growth. In the resin composites, both decreased particle size and increased compression resulted in increased mechanical strength, while a moderate DDGS content was found to increase flexural strength but decrease Young's modulus. These results indicate that DDGS has the potential to be used in resin glue-based composites to both improve flexural strength and improve potential biodegradability.

AN - 734200011; 20016738 AB - Conjugated linoleic acids (CLA) were identified in 1980's, since then it has been intensively studied due to its various beneficial health effects such as anti-inflammatory, anti-atherogenic, anti-carcinogenic and anti-diabetic/obesity effects. Isomer specificity of a number of CLA isomers, especially predominant isomer 9Z,11E- and 10E,12Z-CLA, is now recognized. However, the less prevalent CLA isomers have not been well characterized. Recently, studies have reported the distinctively different effects of 9E,11E-CLA in colon cancer cells, endothelial cells, and macrophage cells compared to the rest of CLA isomers. In this review, various effects of CLAs, especially anti-inflammatory and anti-atherogenic effects, will be discussed with focusing on the isomer-specific effects and potential mechanism of action of CLA.

AN - 70767770; 18048372 AB - The large, alpha-isoform of Rubisco activase confers redox regulation of the ATP/ADP response of the ATP hydrolysis and Rubisco activation activities of the multimeric activase holoenzyme complex. The alpha-isoform has a C-terminal extension that contains the redox-sensitive cysteine residues and is characterized by a high content of acidic residues. Cross-linking and site-directed mutagenesis studies of the C-terminal extension that have provided new insights into the mechanism of redox regulation are reviewed. Also reviewed are new details about the interaction between activase and Rubisco and the likely mechanism of 'activation' that resulted from mutagenesis in a 'Sensor 2' domain of activase that AAA(+) proteins often use for substrate recognition. Two activase residues in this domain were identified that are involved in Rubisco recognition. The results directly complement earlier studies that identified critical residues for activase recognition in the large subunit of Rubisco.

AN - 70446643; 18374187 AB - To understand the role of vitamin K in human health, it is important to identify determinants of vitamin K status throughout the life cycle. Our current understanding of vitamin K physiology and metabolism only partially explains why there is wide interindividual variation in vitamin K status, as measured by various biochemical measures. Dietary intake of vitamin K is one of the primary determinants of vitamin K status, and intakes vary widely among age groups and population subgroups. How dietary sources of vitamin K are absorbed and transported varies with the form and food source of vitamin K. Likewise, the role of plasma lipids as a determinant of vitamin K status varies with the form of vitamin K ingested. There is also some evidence that other fat-soluble vitamins antagonize vitamin K under certain physiological conditions. Infants are at the greatest risk of vitamin K deficiency because of a poor maternal-fetal transfer across the placenta and low vitamin K concentrations in breast milk. During adulthood, there may be subtle age-related changes in vitamin K status but these are inconsistent and may be primarily related to dietary intake and lifestyle differences among different age groups. However, there is some suggestion that absence of estrogen among postmenopausal women may be a determinant of vitamin K, status. Genetics may explain some of the observed interindividual variability in vitamin K, but to date, there are few studies that have systematically explored the associations between individual genetic polymorphisms and biochemical measures of vitamin K status.

On the basis of 24-h LD50 values after topical application, the only pesticide that had higher activity than permethrin was fipronil, with LD50 values lower than permethrin for 107-, 4,849-, and 2-fold against Ae. aegypti, Cx. quinquefasciatus Say, and An. quadrimaculatus Say, respectively. Abamectin, imidacloprid, spinosad, diazinon, and carbaryl showed slightly lower activity than permethrin (1000-fold. On the basis of 24-h LD50 values, Cx. quinquefasciatus was the least susceptible species to nine pesticides tested (DNOC, azocyclotin, chlorfenapyr, carbaryl, spinosad, imidaclorid, diazinon, abamectin, and permethrin) , whereas Ae. aegypti was the least susceptible species to six pesticides tested (dicofol, amitraz, propargite, hydramethylnon, cyhexatin, and diafenthiuron), and An. quadrimaculatus was the least susceptible species to four pesticides tested (bifenazate, pyridaben, indoxacarb, and fipronil). Our results revealed that different species of mosquitoes had different susceptibility to pesticides, showing the need to select the most efficacious compounds for the least susceptible mosquito species to achieve successful mosquito control.

AN - 70257191; 18236664 AB - As part of a biofilm in a floor drain, Listeria monocytogenes is exceedingly difficult to eradicate with standard sanitizing protocols. The objective of these studies was to test the use of ultrasonication to break up biofilm architecture and allow chemical sanitizers to contact cells directly. L. monocytogenes biofilms were created in model polyvinyl chloride drain pipes. Chemical sanitizers (quaternary ammonium, peroxide, or chlorine) were applied to the drain pipes with and without a 30-s ultrasonication treatment. Controls using sterile water were included for comparison. L. monocytogenes cells were enumerated from the liquid in the drain and the inside wall surface of the pipe. All chemicals lowered numbers of planktonic cells from 6.6 log CFU/ml in the water control to < 100 CFU/ml. Attached cells were also affected by the chemical sanitizers. Approximately 6.0 log CFU/cm2 of the inner wall surface was detected in water control pipes, and ultrasonication did not lower these numbers. With or without ultrasonication, the peroxide-based sanitizer was effective for reducing the numbers of attached L. monocytogenes cells, resulting in approximately 2.0 log CFU/cm2. Both the chlorine- and quaternary ammonium-based sanitizers reduced the number of attached L. monocytogenes cells to a lesser degree, resulting in 4.2 to 4.4 log CFU/cm2. However, addition of ultrasonication improved the performance of both these sanitizers, causing a further reduction to 3.1 and 2.9 CFU/ cm2 for quaternary ammonium- and chlorine-based chemicals, respectively. These results indicate that a peroxide-based sanitizer alone can be very effective against biofilm L. monocytogenes in drain pipes, and the addition of ultrasonication can improve the effectiveness of chlorine or quaternary ammonium sanitizers.

AN - 70228433; 18211358 AB - The objective of this research was to develop an infrared pasteurization process with automatic temperature control for inactivation of surface-contaminated Listeria monocytogenes on ready-to-eat meats such as hotdogs. The pasteurization system contained 4 basic elements: an infrared emitter, a hotdog roller, an infrared sensor, and a temperature controller. The infrared sensor was used to monitor the surface temperature of hotdogs while the infrared emitter, modulated by a power controller, was used as a heating source. The surface temperature of hotdogs was increased to set points (70, 75, 80, or 85 degrees C), and maintained for bacterial kill. The infrared surface pasteurization was evaluated using hotdogs that were surface-inoculated with a 4-strain L. monocytogenes cocktail to an average initial inoculum of 7.32 log (CFU/g). On the average 1.0, 2.1, 3.0, or 5.3 log-reduction in L. monocytogenes was observed after the surface temperature of hotdogs was increased to 70, 75, 80, or 85 degrees C, respectively. Holding the sample temperature led to additional bacterial inactivation. With a 3 min holding at 80 degrees C or 2 min at 85 degrees C, a total of 6.4 or 6.7 logs of L. monocytogenes were inactivated. This study demonstrated that the infrared surface pasteurization was effective in inactivating L. monocytogenes in RTE meats.

Spatial analysis of transcript levels for white in larval Hessian fly tissues by quantitative real-time PCR revealed the greatest level of transcript in the Malpighian tubules, while analysis of temporal expression during development revealed the highest transcript levels in late 2nd- and early 3rd-instar larvae. Analysis of transcript levels for white in Hessian fly larvae feeding on susceptible and resistant wheat showed greater levels of the transcript in larvae feeding on resistant plants. We speculate the increased transcript level for white in larvae feeding on resistant wheat could be correlated with stress and increased Malpighian tubule activity associated with the metabolism and detoxification of toxic substrates generated either endogenously or encountered exogenously from the host plant.

AN - 70211470; 18060459 AB - Locoweeds (Astragalus and Oxytropis spp. that contain the toxic alkaloid swainsonine) cause widespread poisoning of livestock on western rangelands. There are 354 species of Astragalus and 22 species of Oxytropis in the US and Canada. Recently, a fungal endophyte, Embellisia spp., was isolated from Astragalus and Oxytropis spp. and shown to produce swainsonine. We conducted a survey of the major locoweeds from areas where locoweed poisoning has occurred to verify the presence of the endophyte and to relate endophyte infection with swainsonine concentrations. Species found to contain the fungal endophyte and produce substantial amounts of swainsonine were A. wootoni, A. pubentissimus, A. mollissimus, A. lentiginosus, and O. sericea. Astragalus species generally had higher concentrations of swainsonine than Oxytropis. Swainsonine was not detected in A. alpinus, A. cibarius, A. coltonii, A. filipes, or O. campestris. The endophyte could not be cultured from A. mollissimus var. thompsonii or A. amphioxys, but was detected by polymerase chain reaction, and only 30% of these samples contained trace levels of swainsonine. Further research is necessary to determine if the endophyte is able to colonize these and other species of Astragalus and Oxytropis and determine environmental influences on its growth and synthesis of swainsonine.

AN - 70202836; 17912680 AB - Estimates of arthropod population size may paradoxically increase following insecticide applications. Research with ground beetles (Coleoptera: Carabidae) suggests that such unusual results reflect increased arthropod movement and capture in traps rather than real changes in population size. However, it is unclear whether direct (hyperactivity) or indirect (prey-mediated) mechanisms produce increased movement. Video tracking of Scarites quadriceps Chaudior indicated that brief exposure to lambda-cyhalothrin or tefluthrin increased total distance moved, maximum velocity and percentage of time moving. Repeated measurements on individual beetles indicated that movement decreased 240 min after initial lambda-cyhalothrin exposure, but increased again following a second exposure, suggesting hyperactivity could lead to increased trap captures in the field. Two field experiments in which ground beetles were collected after lambda-cyhalothrin or permethrin application attempted to detect increases in population size estimates as a result of hyperactivity. Field trials used mark-release-recapture methods in small plots and natural carabid populations in larger plots, but found no significant short-term (<6 day) increases in beetle trap captures. The disagreement between laboratory and field results suggests mechanisms other than hyperactivity may better explain unusual changes in population size estimates. When traps are used as a primary sampling tool, unexpected population-level effects should be interpreted carefully or with additional data less influenced by arthropod activity.

AN - 70190184; 18178873 AB - Federal and state regulations are being promulgated under the Clean Air Act to reduce hazardous air emissions from livestock operations. Few data are available on emissions from livestock facilities in the USA and the management practices that may minimize emissions. The objective of this study was to measure seasonal and bedding impacts on ammonia emissions from tie-stall dairy barns located in central Wisconsin. Four chambers each housed four Holstein dairy heifers (approximately 17 mo of age; body weights, 427-522 kg) for three 28-d trial periods corresponding to winter, summer, and fall. A 4x4 Latin Square statistical design was used to evaluate four bedding types (manure solids, chopped newspaper, pine shavings, and chopped wheat straw) in each chamber for a 4-d ammonia monitoring period. Average ammonia-N emissions (g heifer(-1) d(-1)) during summer (20.4) and fall (21.0) were similar and twice the emissions recorded during winter (10.1). Ammonia-N emissions accounted for approximately 4 to 7% of consumed feed N, 4 to 10% of excreted N, and 9 to 20% of manure ammonical N. Cooler nighttime temperatures did not result in lower ammonia emissions than daytime temperatures. Ammonia emissions (g heifer(-1) d(-1)) from chambers that contained manure solids (20.0), newspaper (18.9), and straw (18.9) were similar and significantly greater than emissions using pine shavings (15.2). Chamber N balances, or percent difference between the inputs feed N and bedding N, and the outputs manure N, body weight N, and ammonia N were 105, 90, and 89% for the winter, summer, and fall trials, respectively. Relatively high chamber N balances and favorable comparisons of study data with published values of ammonia emissions, feed N intake, and manure N excretion provided confidence in the accuracy of the study results.

AN - 70188175; 18178882 AB - Management practices can influence soil CO(2) emission and C content in cropland, which can effect global warming. We examined the effects of combinations of irrigation, tillage, cropping systems, and N fertilization on soil CO(2) flux, temperature, water, and C content at the 0- to 20-cm depth from May to November 2005 at two sites in the northern Great Plains. Treatments were two irrigation systems (irrigated vs. non-irrigated) and six management practices that contained tilled and no-tilled malt barley (Hordeum vulgaris L.) with 0 to 134 kg N ha(-1), no-tilled pea (Pisum sativum L.), and a conservation reserve program (CRP) planting applied in Lihen sandy loam (sandy, mixed, frigid, Entic Haplustolls) in western North Dakota. In eastern Montana, treatments were no-tilled malt barley with 78 kg N ha(-1), no-tilled rye (Secale cereale L.), no-tilled Austrian winter pea, no-tilled fallow, and tilled fallow applied in dryland Williams loam (fine-loamy, mixed Typic Argiborolls). Irrigation increased CO(2) flux by 13% compared with non-irrigation by increasing soil water content in North Dakota. Tillage increased CO(2) flux by 62 to 118% compared with no-tillage at both places. The flux was 1.5- to 2.5-fold greater with tilled than with non-tilled treatments following heavy rain or irrigation in North Dakota and 1.5- to 2.0-fold greater with crops than with fallow following substantial rain in Montana. Nitrogen fertilization increased CO(2) flux by 14% compared with no N fertilization in North Dakota and cropping increased the flux by 79% compared with fallow in no-till and 0 kg N ha(-1) in Montana. The CO(2) flux in undisturbed CRP was similar to that in no-tilled crops. Although soil C content was not altered, management practices influenced CO(2) flux within a short period due to changes in soil temperature, water, and nutrient contents. Regardless of irrigation, CO(2) flux can be reduced from croplands to a level similar to that in CRP planting using no-tilled crops with or without N fertilization compared with other management practices.

AN - 70099322; 17992532 AB - The green alga Chlamydomonas reinhardtii is a convenient model organism for the study of basic biological processes, including DNA repair investigations. This review is focused on the studies of DNA repair pathways in C. reinhardtii. Emphasis is given to the connection of DNA repair with other cellular functions, namely the regulation of the cell cycle. Comparison with the results of repair investigations that are already available revealed the presence of all basic repair pathways in C. reinhardtii as well as special features characteristic of this alga. Among others, the involvement of UVSE1 gene in recombinational repair and uniparental inheritance of chloroplast genome, the specific role of TRXH1 gene in strand break repair, the requirement of PHR1 gene for full activity of PHR2 gene, or encoding of two excision repair proteins by the single REX1 gene. Contrary to yeast, mammals and higher plants, C. reinhardtii does not appear to contain the ortholog of RAD6 gene, which plays an important role in DNA translesion synthesis and mutagenesis. Completed genome sequences will be a basis for molecular analyses allowing to explain the differences that have been observed in DNA repair of this alga in comparison with other model organisms.

AN - 70094639; 17588734 AB - Selenium is an essential dietary component for animals including humans, and there is increasing evidence for the efficacy of certain forms of selenium as cancer-chemopreventive compounds. In addition, selenium appears to have a protective effect at various stages of carcinogenesis including both the early and later stages of cancer progression. Mechanisms for selenium-anticancer action are not fully understood; however, several have been proposed: antioxidant protection, enhanced carcinogen detoxification, enhanced immune surveillance, modulation of cell proliferation (cell cycle and apoptosis), inhibition of tumor cell invasion and inhibition of angiogenesis. Research has shown that the effectiveness of selenium compounds as chemopreventive agents in vivo correlates with their abilities to affect the regulation of the cell cycle, to stimulate apoptosis and to inhibit tumor cell migration and invasion in vitro. This article reviews the status of knowledge concerning selenium metabolism and its anticancer effects with particular reference to the modulation of cell proliferation and the inhibition of tumor cell invasion.

AN - 69420160; 18695957 AB - Conventional methods to detect Salmonella spp. in foodstuffs may take up to 1 wk. Methods for pathogen detection are required. Real-time detection of Salmonella spp. will broaden our ability to screen large number of samples in a short time. This chapter describes a step-by-step procedure using an oligonucleotide probe that becomes fluorescent upon hybridization to the target DNA (Molecular Beacon; MB) in a real-time polymerase chain reaction (PCR) assay. The capability of the assay to detect Salmonella species from artificially inoculated fresh- and fresh-cut produce as well as ready-to-eat meats is demonstrated. The method uses internal positive and negative controls which enable researchers to detect false-negative PCR results. The procedure uses the buffered peptone water for the enrichment of Salmonella spp. and successfully detects the pathogen at low level of contamination (2-4 cells/25 g) in <24 h.

AN - 69299680; 18610545 AB - Solar drying has been used extensively to dewater biosolids for ease of transportation and to a lesser degree to reduce pathogens prior to land application. The nitrogen in biosolids makes them a relatively inexpensive but valuable source of fertilizer. In this study, nitrogen loss from tilled and untilled biosolids was investigated during the solar drying process. Samples of aerobically and anaerobically digested biosolids during three solar drying experiments were analyzed for their nitrate (NO3-) and ammonium (NH4+) ions concentrations. Nitrogen losses varied depending on the solar drying season and tillage. Although not directly measured, the majority of nitrogen loss occurred through ammonia volatilization; organic nitrogen content (organic N) remained relatively stable for each sample, nitrate concentrations for the majority of samples remained below detectable levels and the decline of ammonium-nitrogen (NH4(+)-N) generally followed the trend of moisture loss in the biosolids.

AN - 66690759; 19226818 AB - Understanding the evaporation of pesticide droplets and wetting of Leaf surfaces can increase foliar application efficiency and reduce pesticide use. Evaporation time and wetted area of single pesticide droplets on hairy and waxy geranium leaf surfaces were measured under the controlled conditions for five droplet sizes and three relative humidities. The sprays used to form droplets included water, a nonionic colloidal polymer drift retardant, an alkyl polyoxyethylene surfactant, and an insecticide. Adding the surfactant into spray mixtures greatly increased droplet wetted area on the surfaces while droplet evaporation time was greatly reduced. Adding the drift retardant into spray mixture slightly increased the droplet evaporation time and the wetted area. Also, droplets had Longer evaporation times on waxy leaves than on hairy leaves for all droplet diameters and all relative humidity conditions. Increasing relative humidity could increase the droplet evaporation time greatly but did not change the the wetted area. The droplet evaporation time and wetted area increased exponentially as the droplet size increased. Therefore, droplet size, surface characteristics of the target, relative humidity, and chemical composition of the spray mixtures (water alone, pesticide, additives) should be included as important factors that affect the efficacy and efficiency of pesticide applications.

We examine differences between Canada and the United States in the prevalence and distribution of household-level, income-related food insecurity as a step toward understanding effects of economic, policy, and program factors on food security. We use nationally representative data on the food security of Canadian households from the 2004 Canadian Community Health Survey Cycle 2.2 (CCHS 2.2) and United States households from the 2003, 2004, and 2005 Current Population Survey Food Security Supplements (CPS-FSS). The two surveys used the same 18-item Household Food Security Survey Module, but Health Canada and the United States Department of Agriculture combined responses in somewhat different ways to determine the food security status of households. We examine effects of the methodological differences. Then, applying the Health Canada classification protocol to the data from both countries, we compare Canadian and US food insecurity rates nationally and for selected subpopulations. Food insecurity was substantially less prevalent in Canada than in the United States (9.0% vs 14.1% using the Canadian adult food security measure). The difference was larger in households with children, for which the prevalence rate of food insecurity in Canada was about half that in the United States. These differences reflected primarily differences in food insecurity prevalence rates within each income adequacy range rather than differences in income distribution between the two countries.

Three sensitivity classes are assigned, based on similarities in the degree and rapidity of change to soil properties and plant communities following disturbance, as well as return interval to the pre-disturbance condition. The model aggregates ecological sites into groups with similar plant community structure and species richness, two elements useful in evaluating wildlife habitat. Dynamic soil properties, such as thickness of organic mat. depth to water table, and permafrost, may also be estimated for the various ecological states identified for each sensitivity class. This information is useful for estimating transient carbon budgets in soils and hydrologic functions, as well as indicating soils that are likely to be impacted by climate change. Gelisols considered highly sensitive to disturbance comprise 118.185 ha. or about 4% of Denali. Moderately sensitive Gelisols comprise 445.192 ha, or 18% of Denali. Gelisols considered low in sensitivity include 391;760 ha, or about 16% of Denali. JF - International Conference on Permafrost (ICOP) Proceedings AU - Clark, Mark H A2 - Kane, Douglas L.

This study measures the potential of three-dimensional ground-penetrating radar (3D GPR) techniques to detect and identify subsurface cryogenic macrostructures investigated previously in the region, including deformed wedges. sediment-filled pots, and frost-fissure casts. Radar images are especially useful where infill is sandy, and the host sediments are indurated. Although geometric relations between cryostructures are more subtle than in the few contemporary permafrost environments where 3D GPR has been employed and interpretation is more difficult, the ability of 3D GPR to detect networks of fossil features warrants further investigation. The methodology complements traditional field observation and appears to have considerable potential as a tool for detecting and analyzing networks of relict subsurface permafrost features.

Utilizing the random utility and random profit difference approaches, the paper develops a theoretical model that explains why farmers may require a premium in excess of the decrease in profits to adopt a conservation plan, and may even require a premium in the case where adoption of the plan is associated with a mean increase in profits. This premium is estimated using a survey of farmers in conjunction with predictions of changes in production costs. Reprinted by permission of Carfax Publishing, Taylor & Francis Ltd.

Predisposition to passive dispersal, or more definitively, stochastic anthropogenic dispersal, results from human-assisted movement of infested ash (Fraxinus spp.) firewood, nursery stock, logs, or wood packaging material containing viable EAB life stages from an infested area (Muirhead et al 2006). Most EAB infestations outside the original six infested counties in southeastern Michigan have occurred through this human-assisted dispersal method (Smitely et al 2008).

Detection was accomplished using mass spectrometers attached to each of the two liquid chromatographic systems, for a dual liquid chromatography/dual mass spectrometry (LC2/MS2) arrangement. This experimental approach is demonstrated to be useful to identify many classes of polar and non-polar lipids, and numerous individual molecular species within each class, which is a primary goal of lipidomics. Data are presented from a bovine brain total lipid extract and a sand bream filet extract as examples. The use of both ESI-MS and APCI-MS are demonstrated for analysis of non-polar lipids, and advantages and shortcomings of each technique are discussed. The two parallel chromatographic separations are compared to lipidomics approaches that employ infusion without chromatography. The data show that the LC2/MS2 is one approach to a comprehensive total lipid analysis that can be performed using only commercially available instruments with no fabrication or modification required. The LC2/MS2 approach represents a uniquely valuable tool for monitoring the amounts of precursors and products of molecules involved in cell signaling processes. The dual liquid chromatography/dual mass spectrometry approach represents one of the most powerful tools for lipidomics analysis reported to date.

Oligodeoxynucleotides containing CpG motifs (CpG ODN) mimic microbial DNA and are immunostimulatory to most vertebrate species. In the present study, we used the production of nitric oxide (NO) as an indicator to evaluate the involvement of the signaling cascades of phospholipases and phosphatidylinositol 3-kinase (PI3K) in the activation of chicken HD11 macrophage cells by CpG ODN. Using selective inhibitors, we have identified the involvement of phosphatidylinositol (PI)-phospholipase C (PI-PLC), but not phosphatidylcholine (PC)-phospholipase C (PC-PLC) and PC-phospholipase D (PC-PLD), in CpG ODN-induced NO production in HD11 cells. Preincubation with PI-PLC selective inhibitors (U-73122) completely abrogated CpG ODN-induced NO production in HD11 cells, whereas PC-PLC inhibitor (D609) and PC-PLD inhibitor (n-butanol) had no inhibitory effects. Additionally, inhibition of PI3K and protein kinase C (PKC) with selective inhibitors and chelation of intracellular [Ca super(2+)] also significantly attenuated NO production in CpG ODN-activated HD11 cells. Our results demonstrate that PI-PLC, PI3 K, PKC, and intracellular [Ca super(2+)] are important components of the CpG ODN-induced signaling pathway that leads to the production of NO in avian macrophage cells.

Egg producers can impose an induced molt on older hens that results in increased egg productivity and decreased hen mortality compared with non-molted hens of the same age. This review discusses the effect of induced molting by feed removal on immune parameters, Salmonella enterica serovar Enteritidis (SE) invasion and subsequent production of SE-contaminated eggs. Experimental oral infections with SE show molted hens are more susceptible to SE infection and produce more SE-contaminated eggs in the first few weeks post-molt compared with pre-molt egg production. In addition, it appears that molted hens are more likely to disseminate SE into their environment. Molted hens are more susceptible to SE infection by contact exposure to experimentally infected hens; thus, transmission of SE among molted hens could be more rapid than non-molted birds. Histological examination of the gastrointestinal tracts of molted SE-infected hens revealed more frequent and severe intestinal mucosal lesions compared with non-molted SE-infected hens. These data suggest that induced molting by feed deprivation alters the normal asymptomatic host- pathogen relationship. Published data suggest the highest proportion of SE- positive eggs is produced within 1-5 weeks post-molt and decreases sharply by 6-10 weeks and dissipates to the background level for non-molted hens by 11- 20 weeks. Appropriate treatment measures of eggs produced in the fist 5 weeks post-molting may decrease the risk of foodborne infections to humans.

Seven pairs of no-till and conventional till farms under a corn-soybean rotation were selected on soils ranging from sandy loam to silty clay loams. The relative importance of surface residue and macroporosity (number of earthworms and middens) in both tillage systems was evaluated through the use of three different infiltration measurement techniques, and by the removal or addition of surface residue. The results of the ponded infiltration tests indicate that on the silt loam and silty clay loam soils, no-till farms had higher infiltration rates than those of conventional farms when earthworm activity and/or residue amount were higher in the no-till farms. On sandy loam soil, when earthworm activities were similar for both no-till and conventional farms, conventional farms had higher infiltration rates than the no-till farms. Under simulated rainfall, placing residue cover on the conventional plots generally increased final infiltration rates for silt loam and silty clay loam soils. Furthermore, in the absence of plant residues, the no-till farms had equal and/or significantly higher infiltration rates than the corresponding conventional farms on the sites with silt loam and silty clay loam soils. As was the case with ponding infiltration, the terminal infiltration rate for the no-till farm was less with the rainfall simulator than for the conventional farm, at the site with sandy loam soil.

The utility of field-scale flow and transport studies, however, is frequently limited by our inability to characterize the heterogeneous distribution of hydraulic properties at these sites. In this study, we present an integrated approach, using both "hard" and "soft" data sets of field and laboratory scales in conjunction with pedotransfer functions, interpolation algorithm, and numerical modeling to characterize the hydraulic properties of the vadose zone. The approach is demonstrated at two 5- by 5-m field plots selected for research on the transport and fate of nutrients and pathogens. We used hard data to quantify the magnitude of the hydraulic properties at selected locations in these plots and included laboratory and field measurements of the hydraulic properties from undisturbed cores and the instantaneous profile method, respectively. More abundant soft data included inductive electromagnetic readings and approximate particle-size distribution information. The nearest neighbor interpolation algorithm was used to generate a heterogeneous realization of the saturated hydraulic conductivity on these plots. Numerical modeling of steady-state water infiltration and redistribution experiments was used to compare laboratory- and field-scale hydraulic properties and to refine our conceptual model of the vertical and lateral flow at this site. Good agreement between simulated and measured water contents and water pressure heads was obtained, indicating that field- scale hydraulic properties were accurately quantified for these conditions. This article provides a real-world example of how to combine information and approaches to tackle the difficult challenge of characterizing the hydraulic properties at a field site.

Often, large-scale genomic research projects require high-throughput computer-assisted primer design. Numerous such web-based or standard-alone programs for PCR primer design are available but vary in quality and functionality. In particular, most programs lack batch primer design capability. Such a high-throughput software tool for designing SSR flanking primers and SNP genotyping primers is increasingly demanded. Results A new web primer design program, BatchPrimer3, is developed based on Primer3. BatchPrimer3 adopted the Primer3 core program as a major primer design engine to choose the best primer pairs. A new score-based primer picking module is incorporated into BatchPrimer3 and used to pick position-restricted primers. BatchPrimer3 v1.0 implements several types of primer designs including generic primers, SSR primers together with SSR detection, and SNP genotyping primers (including single-base extension primers, allele-specific primers, and tetra-primers for tetra-primer ARMS PCR), as well as DNA sequencing primers. DNA sequences in FASTA format can be batch read into the program. The basic information of input sequences, as a reference of parameter setting of primer design, can be obtained by pre-analysis of sequences. The input sequences can be pre-processed and masked to exclude and/or include specific regions, or set targets for different primer design purposes as in Primer3Web and primer3Plus. A tab-delimited or Excel-formatted primer output also greatly facilitates the subsequent primer-ordering process. Thousands of primers, including wheat conserved intron-flanking primers, wheat genome-specific SNP genotyping primers, and Brachypodium SSR flanking primers in several genome projects have been designed using the program and validated in several laboratories. Conclusion BatchPrimer3 is a comprehensive web primer design program to develop different types of primers in a high-throughput manner. Additional methods of primer design can be easily integrated into future versions of BatchPrimer3. The program with source code and thousands of PCR and sequencing primers designed for wheat and Brachypodium are accessible at .

All tested washing waters reduced root dry mass, whereas the dry mass of shoots was either not affected or increased. Generally, their effects were stronger on fresh than on dry mass production, indicating problems in water reception and translocation. The adverse effect on photosynthetic pigment production increased with redundant concentration very slowly, and was stronger for chlorophyll a than for chlorophyll b. Opposite to chlorophylls, carotenoid levels remained constant or increased in presence of the tested washing wastewaters, compared to their content in control samples. The accumulation of Cr was higher in the roots, and Ni was distributed equally through the whole plant seedlings. Cr average uptake in roots and shoots was about 1.7 and 7.3 times, respectively, and lower than that of Ni. Ni percentage uptake from washing waters in roots and shoots was nearly equal ranging from 10.2 to 15.8%.

This study evaluated the effects of thermal energy input on soil water repellency of sandy forest soils from Slovakia and explored the processes underlying the changes observed using thermal analysis. Initial sample water drop penetration time values ranged from 43,200 s. Heating induced distinct increases in water repellency to >3600 s in most samples, with its elimination occurring at 175 degree C or higher. The thermal analysis allowed evaluation of the relationship between the destruction of soil water repellency and thermal changes affecting soil organic matter (SOM). Differences in the thermal resistance of soil water repellency correspond to the thermal stability of SOM. Kinetic analysis showed that water repellency elimination due to soil heating is linked with thermal decomposition of a more thermally labile pool of SOM. The results suggest that under nonisothermal conditions, the degree of SOM decomposition depends on both the soil temperature reached and the soil heating rate. The temperature at which a certain level of SOM decomposition is reached increases with increasing heating rate. Heating experiments and the kinetic evaluation of thermogravimetric data for isothermal conditions also demonstrated an exponential relationship between heating durations and temperature thresholds.

Despite the fact that this is a microbial process, little is known about how the microbial populations, especially ammonia-producing (ureolytic) organisms in poultry litter, respond to litter amendments such as aluminum sulfate (Al sub(2)(SO sub(4)) sub(3) super(.)14H sub(2)O; alum). The goal of this study was to measure the temporal changes in total bacterial and fungal populations and urease-producing microorganisms in nontreated litter or litter treated with 10% alum. Quantitative real-time polymerase chain reaction was used to target the bacterial 16S rRNA gene, the fungal 18S rRNA gene, or the urease gene of bacterial and fungal ammonia producers in a poultry litter incubation study. Nontreated poultry litter had relatively high total (2.8 plus or minus 0.8 x 10 super(10) cells g super(-1) litter) and ureolytic (2.8 plus or minus 1.3 x 10 super(8) cells g super(-1) litter) bacterial populations. Alum treatment reduced the total bacterial population by 50% and bacterial urease producers by 90% within 4 wk. In contrast, at 16 wk after alum treatment, the fungal population was three orders of magnitude higher in alum-treated litter than in nontreated litter (3.5 plus or minus 0.8 x 10 super(7) cells g super(-1) litter and 5.5 plus or minus 2.5 x 10 super(4) cells g super(-1) litter, respectively). The decrease in pH produced by alum treatment is believed to inhibit bacterial populations and favor growth of fungi that may be responsible for the mineralization of organic nitrogen in alum-treated litters.

This method is routinely used to validate whole transcriptome analyses such as DNA microarrays, suppressive subtractive hybridization (SSH) or differential display techniques such as cDNA-AFLP (Amplification Fragment Length Polymorphism). Despite efforts to optimize the methodology, misleading results are still possible, even when standard optimization approaches are followed. Results As part of a larger project aimed at elucidating transcriptome-level responses of Pacific oysters (Crassostrea gigas) to various environmental stressors, we used microarrays and cDNA-AFLP to identify Expressed Sequence Tag (EST) fragments that are differentially expressed in response to bacterial challenge in two heat shock tolerant and two heat shock sensitive full-sib oyster families. We then designed primers for these differentially expressed ESTs in order to validate the results using Q-PCR. For two of these ESTs we tested fourteen primer pairs each and using standard optimization methods (i.e. melt-curve analysis to ensure amplification of a single product), determined that of the fourteen primer pairs tested, six and nine pairs respectively amplified a single product and were thus acceptable for further testing. However, when we used these primers, we obtained different statistical outcomes among primer pairs, raising unexpected but serious questions about their reliability. We hypothesize that as a consequence of high levels of sequence polymorphism in Pacific oysters, Q-PCR amplification is sub-optimal in some individuals because sequence variants in priming sites results in poor primer binding and amplification in some individuals. This issue is similar to the high frequency of null alleles observed for microsatellite markers in Pacific oysters. Conclusion This study highlights potential difficulties for using Q-PCR as a validation tool for transcriptome analysis in the presence of sequence polymorphism and emphasizes the need for extreme caution and thorough primer testing when assaying genetically diverse biological materials such as Pacific oysters. Our findings suggest that melt-curve analysis alone may not be sufficient as a mean of identifying acceptable Q-PCR primers. Minimally, testing numerous primer pairs seems to be necessary to avoid false conclusions from flawed Q-PCR assays for which sequence variation among individuals produces artifactual and unreliable quantitative results.

Little is known about the nature and extent of antigenic variation in p57. Previously, we reported that p57 produced by Renibacterium salmoninarum Strain 684 contains a mutation that disrupts monoclonal antibody (MAb) 4C11 binding. In the present study, we examined MAb binding to a panel of 23 additional R. salmoninarum isolates obtained from diverse geographic locations to examine the prevalence of this variant and whether additional variability exists within other p57 epitopes. Six p57-specific MAbs (4C11, 4D3, 3H1, 4H8, 4D10 and 1A1) were used to probe dot and western blots to determine the relative expression, size and cellular association of p57. Full-length p57 was produced by all isolates, and for each isolate, the protein was associated with the bacterial cell surface. The epitopes recognized by 4 MAbs, 4D3, 4H8, 3H1 and 1A1, were conserved among all strains tested. The 4C11 epitope was absent in 5 of 8 strains originating from Norway, while the 4D10 epitope was partially disrupted in one isolate from British Columbia, Canada. The 5 Norwegian antigenic-variant strains appeared to be clonally related as they shared the following characteristics: one tandem repeat in the ETRA locus, a Sequovar-4 16-23S rRNA intervening DNA sequence, a larger XhoI fragment in the msa1 5' region, and absent msa3 gene. These results indicate that limited antigenic and genomic variation exists between strains and this variation appears geographically restricted in distribution.

Fast pyrolyzers thermally transform biomass into bio-oil, syngas, and charcoal. The syngas could provide the energy needs of the pyrolyzer. Bio-oil is an energy raw material ( similar to 17 MJ kg super(-1)) that can be burned to generate heat or shipped to a refinery for processing into transportation fuels. Charcoal could also be used to generate energy; however, application of the charcoal co-product to soils may be key to sustainability. Application of charcoal to soils is hypothesized to increase bioavailable water, build soil organic matter, enhance nutrient cycling, lower bulk density, act as a liming agent, and reduce leaching of pesticides and nutrients to surface and ground water. The half-life of C in soil charcoal is in excess of 1000 yr. Hence, soil-applied charcoal will make both a lasting contribution to soil quality and C in the charcoal will be removed from the atmosphere and sequestered for millennia. Assuming the United States can annually produce 1.1 x 10 super(9) Mg of biomass from harvestable forest and crop lands, national implementation of The Charcoal Vision would generate enough bio-oil to displace 1.91 billion barrels of fossil fuel oil per year or about 25% of the current U.S. annual oil consumption. The combined C credit for fossil fuel displacement and permanent sequestration, 363 Tg per year, is 10% of the average annual U.S. emissions of CO sub(2)-C.

In this study, we exploited this correlation and developed a model for predicting thermal damage to thylakoids. Prediction is based on estimation of the ratio of constant chlorophyll a fluorescence (O) and the peak of variable fluorescence (P) (O/P). The model was developed using 12 cultivars of hexaploid winter wheat (Triticum aestivum L.). It was tested in six genotypes of hexaploid wheat, 25 genotypes of tetraploid wheat (T. turgidum L.), and 20 genotypes of maize (Zea mays L.). Predictive ability was assessed by analyzing the relationship between the predicted and measured O/P. The model adequately predicted O/P and thereby the heat stability of thylakoid membranes in all genotype groups with high coefficients of determination (r super(2) > 0.80). This model could be used as an easy and inexpensive means for detection of the structural and functional state of photosynthetic membranes in wheat and maize, and possibly other crops, in hot environments.

This study evaluated the impact of sampling frequency on the precision of cumulative N sub(2)O flux estimates calculated from field measurements. Automated chambers were deployed in a corn/soybean field and used to measure soil N sub(2)O fluxes every 6 h from 25 Feb. 2006 through 11 Oct. 2006. The chambers were located in two positions relative to the fertilizer bands- directly over a band or between fertilizer bands. Sampling frequency effects on cumulative N sub(2)O-N flux estimation were assessed using a jackknife technique where populations of N sub(2)O fluxes were constructed from the average daily fluxes measured in each chamber. These test populations were generated by selecting measured flux values at regular time intervals ranging from 1 to 21 d. It was observed that as sampling interval increased from 7 to 21 d, variances associated with cumulative flux estimates increased. At relatively frequent sampling intensities (i.e., once every 3 d) N sub(2)O-N flux estimates were within plus or minus 10% of the expected value at both sampling positions. As the time interval between sampling was increased, the deviation in estimated cumulative N sub(2)O flux increased, such that sampling once every 21 d yielded estimates within +60% and -40% of the actual cumulative N sub(2)O flux. The variance of potential fluxes associated with the between-band positions was less than the over-band position, indicating that the underlying temporal variability impacts the efficacy of a given sampling protocol.

Converting from furrow-irrigated to drip-irrigated onion production may reduce N fertilizer needs, water inputs, and NO sub(3)-N leaching potential. Onion growth and N uptake, fresh yield, and residual soil NO sub(3)-N were determined under drip and furrow irrigation on a clay loam soil with N fertilizer rates from 0 to 224 kg N ha super(-1). Onions were sampled bi-weekly from 25 May to 30 August in 2005 and 2006 from each treatment. In 2005, 72% less water was applied with the drip system compared with furrow system, and 57% less in 2006. Onion yields were significantly greater with the drip system. Total marketable fresh onion yield increased with increasing N rate in 2005 only. The drip system had more colossal and jumbo sized onions and less medium sized onions than the furrow system. Biomass production and N accumulation accelerated in mid-June each year with an average total N accumulation (leaves + bulbs) of 121 kg N ha super(-1) at final harvest. Irrigation water use efficiency (IWUE) and N use efficiency (NUE) were higher with the drip system than with the furrow system. Residual soil NO sub(3)-N levels were greater in the drip-irrigated treatments after onion harvest in 2005 than in the furrow-irrigated treatments, but soil NO sub(3)-N levels were similar after harvest in 2006. Adjusted gross economic returns (less the cost of N, water, and drip system) were greater with drip irrigation than with furrow irrigation. This study demonstrates that fresh onion yields, potential economic returns, IWUE, and NUE can be improved in Colorado by using drip irrigation for onion production rather than furrow irrigation.

Recently artificial neural networks (ANNs) have become the tool of choice in PTF development. Recent developments in machine learning methods include the growing research and application of the alternative data-driven method called Support Vector Machines (SVMs). Support Vector Machines have gained popularity in many traditionally ANN dominated fields. Using the SVM eliminates the local minimum issue-the minimum found is always the global one. The objective of this work was to see whethers using the SVM to develop PTFs may have some advantages compared with the ANN. We have used the Soil Profiles Bank of Polish Mineral Soils that includes hydraulic properties for 806 soil samples taken from 290 soil profiles. This database was repeatedly randomly split into training and testing data sets, and both SVMs and ANNs were trained and tested for each split with bulk density, sand and clay as input variables, and water contents at 11 soil water potentials as the output variables. The PTF performance was evaluated by using the test datasets to compute the coefficient of determination, the root-mean-squared error, and the slope and the intercept of the linear regression "predicted vs. measured water contents." The three-parameter SVMs performed mostly better than or with the same accuracy as the eleven- parameter ANNs. The advantage of SVM was more pronounced at soil matric potentials where larger relative errors have been encountered and the correlation between predicted and measured soil water contents was lower. It is worthwhile to consider SVM as a tool to develop PTF.

The objectives of this research were to determine if soybean [Glycine max (L.) Merr.] growth, nutrient uptake, and soil water use could explain whole-plant and seed yield responses to tillage and compost amendment. A corn (Zea mays L.)-soybean-wheat (Triticum aestivum L.)/clover (Trifolium spp.) rotation, with or without fall compost application was initiated in 1998 in plots that had been managed with moldboard plow (MP), chisel plow (CT), or no-tillage (NT) since 1988. No tillage by amendment interaction for yield was detected. Yield was similar in MP and CT. In 2003, yield was similar among tillage systems, but NT yielded 15% greater than MP and CT in 2004 and 8% lower in 2005. Mean yield across the 3 yr was similar. Compost amendment increased yield (9%) compared with nonamended soil only in 2004. Mean yield was 2% higher with compost than without. Water depth from the 0 to 90 cm soil depth was not affected by tillage or amendment. Seed P and K uptake were 18 and 16% greater in NT compared with MP and CT and 16 and 13% greater with compost than without in 2004. Soybean growing on compost-amended soil had less seed protein compared with nonamended soil. Alternatively, seed oil content was 2 and 1% lower in nonamended than amended soil in 2003 and 2004. The mechanisms responsible for compost-enhanced plant growth are difficult to quantify in the field under natural conditions because effects are short-lived or too extreme.

Our objective was to evaluate the effects of crop rotation and N fertilizer management and their stover production characteristics on soil organic carbon (SOC) levels in a long-term high- yielding irrigated study in the western Corn Belt. An irrigated monoculture corn (Zea mays L.), monoculture soybean [Glycine max (L.) Merr.], and soybean-corn cropping systems study was initiated in 1991 on a uniform site in the Platte Valley near Shelton, NE. Soil samples were collected in 1991 before initiation of the study and in the spring of 2005 and analyzed for SOC. Significant differences in total SOC values were obtained between rotations and N rates at the 0- to 7.5- and 0- to 15-cm depths in 2005 and all total SOC values were equal to or greater than SOC values obtained in 1991. Residue production was greater than 6 Mg ha super(-1), a level that appears to be sufficient to maintain SOC levels, in all systems. Can residue amounts above this level be harvested sustainably for biofuel production in cropping systems similar to these? Though these results suggest that a portion of corn stover could be harvested without reducing SOC under the conditions of this investigation, the direct impact of stover removal remains to be evaluated.

Groups participating in stewardship activities range in age, size, and geography and represent an increasingly complex and dynamic arrangement of civil society, government and business sectors. To better understand the structure, function and network of these community-based urban land managers, an assessment was conducted in 2004 by the research subcommittee of the Urban Ecology Collaborative. The goal of the assessment was to better understand the role of stewardship organizations engaged in urban ecology initiatives in selected major cities in the Northeastern U.S.: Boston, New Haven, New York City, Pittsburgh, Baltimore, and Washington, D.C. A total of 135 active organizations participated in this assessment. Findings include the discovery of a dynamic social network operating within cities, and a reserve of social capital and expertise that could be better utilized. Although often not the primary land owner, stewardship groups take an increasingly significant responsibility for a wide range of land use types including street and riparian corridors, vacant lots, public parks and gardens, green roofs, etc. Responsibilities include the delivery of public programs as well as daily maintenance and fundraising support. While most of the environmental stewardship organizations operate on staffs of zero or fewer than ten, with small cohorts of community volunteers, there is a significant difference in the total amount of program funding. Nearly all respondents agree that committed resources are scarce and insufficient with stewards relying upon and potentially competing for individual donations, local foundations, and municipal support.

Aquatic pollutants like phenol, azodyes acid red and indigo carmin have been examined for removal using model solutions and surface functionalized clinoptilolite and its efficiency compared to the other natural or commercial adsorbents, e.g. activated charcoal, pyrolysis char, lignite and expanded perlite. Surface architecture of such zeolite hybrid material has been studied by SEM and HR TEM spectral analytical methods. A satisfying abatement of phenol concentration with the carbonized clinoptilolite regarding the activated charcoal has been achieved using the simulated phenolic wastewaters. Obviously, any phenol removal can be observed using the raw, untreated clinoptilolite. The experimental adsorption data were mathematically best fitted according to Freundlich equation by the carbonized clinoptilolite, while the adsorption data of the activated charcoal were best fitted according to all equations, i.e. Brunauer, Emmett and Teller, Freundlich and Langmuir. Based on the experimental results with azodyes, following conclusions may be drawn: The top efficiency for acid red 1 was achieved with commercial activated charcoal HYS-N, a (max) = 13.5 mg/g, however for acid blue 74 it was achieved with ODA-zeolite (Z3), a (max) = 13.2 mg/g. Oppositely, the carbonized clinoptilolite as some kind of activated charcoal simulation, apparently did not prove any pronounced removal efficiency for acid red. The tendency of affinity increase of the ODA hydrophobized zeolites towards anionic pollutants with the arise of molecular weight has been validated, furthermore.

A review AN - 20947618; 8507649 AB - Nitrogen (N) in agricultural fertilizers is denitrified by soil bacteria when oxygen is limited, which effectively removes plant-available N from the soil to the atmosphere. Reported denitrification rates range from 0 to 239 kg N ha super(-1) yr super(-1), and, depending upon environmental conditions and management, may reduce the amount of N available for crop growth by 27%. Denitrification in soils also results in emissions of nitrous oxide (N sub(2) O), which is a recognized pollutant that contributes to stratospheric ozone destruction and radiative forcing in the troposphere. Practitioners of sustainable agronomy aim to improve plant N-use efficiency and reduce emissions of the greenhouse gases by synchronizing N application and plant nutritional requirements. However, it is difficult to predict denitrification rates during and after the growing season based on current knowledge. High rates are consistently reported in irrigated cropping systems following heavy applications of fertilizer-N, but few studies report denitrification during the dormant season. Denitrification in winter may represent a significant sink for fertilizer-N in cropping systems, but further research at sub-zero soil temperatures is needed. Here, the three factors required for microbial denitrification: limited O sub(2) availability, electron donors and electron acceptors, are reviewed based on soil research performed both above and below 0 degree C. Gaps in the knowledge of denitrification rates in cropping systems, particularly when soils are frozen, are identified. Sustainable management of N in cropping systems such as greater N-use efficiency and lower greenhouse gas emissions could be advanced by greater understanding of denitrification in winter.

'Kanlow' (lowland tetraploid) x 'Summer' (upland tetraploid) hybrids exhibit midparent heterosis for second- and third-year biomass yields for both population and individual plant hybrids. These data and previously reported molecular marker data indicate that lowland- tetraploid and upland-tetraploid switchgrasses represent different heterotic groups that can potentially be used to produce F sub(1) hybrid cultivars. Hybrids produced from cultivars and experimental strains developed from upland-octaploid germplasm originating from spatially separated western and eastern regions of the original tallgrass or an adjacent forested ecoregion did not exhibit heterosis for any trait evaluated. These results suggest that these upland populations evaluated were from the same or closely related large germplasm pools or heterotic groups. A method for developing F sub(1) switchgrass hybrid cultivars utilizing the gametophytic self-incompatibility mechanism of the species is described.

This reduces the utility of transgenic germplasm to the plant breeder and complicates assessments of transgene-encoded phenotypes. Backcrossing transgenes into a wild-type genome is one solution, but producing near-isogenic lines requires a lengthy and resource-intensive process of multiple crosses. However, an abbreviated breeding scheme involving a single backcross to the wild-type parent used to produce a transgenic line, which would replace 75% of the variant alleles, should produce transgenic lines with improved performance. Comparisons were made of 'Conlon' barley (Hordeum vulgare L.), primary transgenic lines derived from Conlon, and lines derived from single backcrosses of primary transgenic lines to Conlon. The primary transgenic lines were different from Conlon for many agronomic and malting characteristics. Most of the backcross-derived lines did not differ significantly from Conlon for most agronomic characteristics. The backcross-derived lines were also similar to Conlon for malting quality traits but showed more differences than for agronomic characteristics. Differences between lines encoding TRI101 versus lines encoding PDR5 suggested that PDR5 insertion or expression may have affected malting quality. It is concluded that a single backcross is an effective, rapid, and inexpensive method for creating superior transgenic lines.

In this study, forages with similar to 200 g CP kg super(-1) dry matter were roll conditioned or macerated, conserved as hay or silage, and then analyzed for CP fractions. Shifting from roll conditioning to maceration of polyphenol-free alfalfa (Medicago sativa L.) reduced buffer soluble protein (SP) with little effect on protease rumen-undegradable protein (RUP) and intestinal available protein (IAP, RUP minus acid-detergent insoluble CP). In birdsfoot trefoil (Lotus corniculatus L.), condensed tannin (CT) and maceration independently reduced SP and increased RUP to yield up to 62% more IAP in hay and 145% more IAP in silage than alfalfa. Based on results with trefoil, roll-conditioned forage with 70 to 120 g CT kg super(-1) CP or macerated forage with more modest CT levels should meet a 350 g RUP kg super(-1) CP target to support 35 kg d super(-1) milk yield by cattle. In roll-conditioned red clover (Trifolium pratense L.), o-quinones formed by polyphenol oxidase reduced SP and increased RUP to yield 50% more IAP in hay and 88% more IAP in silage than alfalfa. Surprisingly, maceration reduced SP, RUP, and IAP in clover. Following maceration, RUP and IAP in conserved clover and trefoil responded similarly to CT, suggesting that maceration disabled o-quinone protection of protein substrates. Although red clover has high RUP, low reported milk yields indicate o-quinones might depress IAP.

This study investigates the possibility of increasing biological control of spirea aphid by providing alternate food resources, in the form of peach extrafloral nectar, to adult Harmonia axyridis, its primary predator. Two pairs of apple orchards, each having one interplanted with 50% trees bearing extrafloral nectar and one a monoculture, were studied for aphid and predator populations from 1999 to 2005. There were no differences in spirea aphid or predator populations between interplanted and monoculture orchards. However, H. axyridis adults arrived earlier in the interplanted than in the monoculture orchards. In another apple orchard, the effect of peach extrafloral nectar on sentinel spirea aphid colonies surrounding a cluster of potted peach trees, or a cluster of apple trees as a control, was tested in 2007. Only the closest spirea colonies to the potted peach trees, trees within 3 m, showed an increase in biological control. Although there was some indication of enhancement of predation by adult H. axyridis on spirea aphids, adding alternative food resources in the form of peach trees bearing extrafloral nectar resulted in no detectable increase in biological control.

These insects often choose their host plant on the basis of the volatile organic compounds (VOCs) emitted. Accordingly, volatile analysis of host plants can provide insight into VOCs that may attract and/or repel the insect. To this end, solid-phase microextraction (SPME) and a customized collection bag were utilized to perform in situ volatile collection on intact and mechanically damaged leaves of Centaurea solstitialis, Centaurea cyanus, and Centaurea cineraria. Volatile identification was performed by GC-MS, and the VOC differences were determined. The plants C. solstitialis and C. cyanus have been reported to attract the weevil, Ceratapion basicorne, a candidate for biological control, whereas C. cineraria does not attract the weevil. Major VOCs unique to C. cineraria include the sesquiterpenes cyclosativene, alpha -ylangene, and trans- alpha -bergamotene. The compound trans- beta -farnesene was unique to C. solstitialis and C. cyanus.

We assessed the effect of pathogen challenge with Edwardsiella ictaluri on five genetic groups of catfish by measuring both phenotypic response (mortality, pathogen levels, specific growth rate), and three measures of immune response, including lysozyme activity and mRNA expression of two toll-like receptors (TLR3 and TLR5). Both mortality and pathogen loads, in addition to non-specific immune response, consistently ranged from the least susceptible Blue catfish (24%, 3.4x10 super(2)+ /-9.3x10 super(1)cell-equivalents/mg, 13.2+/-3.2U/mL tissue, respectively) to the most susceptible 103 channel catfish (65%, 1.1x10 super(4)+ /-6.4x10 super(3)cell-equivalents/mg tissue, 67.3+/-28.7U/mL, respectively). Similarly, specific growth rate was reduced in exposed fish, compared to non-exposed controls, only in the most susceptible genetic groups (P=0.0051). Trends in mRNA expression levels were apparent in each tissue type for both genes. In kidney, differences were evident in expression of both TLR3 and TLR5 mRNA between strains early and late in challenge (P<0.01). TLR5 mRNA showed significant downregulation in all strains on days 1 and 4 (P=0.0001). In spleen, all strains had elevated levels of TLR3 (P=0.0050) and TLR5 mRNA (P<0.0001) only 1day post-exposure. In stomach, only one strain (103xRR) showed upregulation (P=0.0063) throughout challenge. The relationship of phenotypic (mortality and growth) and immune responses measured here, suggests that variation in susceptibility to ESC is a function of differences in innate immune response. Understanding these differences will be crucial for enhancing the immune system through selective breeding and in developing disease management protocols for channel catfish.

The processes responsible for decreases in riparian groundwater NO sub(3) super(-) concentrations in the Willamette Valley of Oregon are not well understood. Our objective was to determine if denitrification and/or dissimilatory NO sub(3) super(-) reduction to NH sub(4) super(+) (DNRA) could explain decreases in groundwater NO sub(3) super(-) moving from a perennial ryegrass cropping system into a mixed-herbaceous riparian area. In situ denitrification rates (DN) were not different between the riparian area (near-stream or near-cropping system) and cropping system the first year. In the second year, during the transition to a clover planting, DN was highest just inside of the riparian/cropping system border. Median denitrification enzyme activity (DEA) rates ranged from 29.5 to 44.6 mg N sub(2)O-N kg super(-1) d super(-1) for surface soils (0-15 cm) and 0.7 to 1.7 mu g N sub(2)O-N kg super(-1) d super(-1) in the subsoil (135-150 cm). Denitrification enzyme activity rates were not different among the zones and were most often correlated to soil moisture and NH sub(4) super(+). Nitrate additions to surface soils increased DEA rates, indicating a potential to denitrify additional NO sub(3) super(-). Based on groundwater velocity estimates, NO sub(3) super(-) (3.8 mg NO sub(3) super(-)-N L super(-1)) entering the riparian surface soil could have been consumed in 0.2 to 7 m by denitrification and 0.03 to 1.0 m by DNRA. Denitrification rates measured in the subsoil could not explain the spatial decrease in NO sub(3) super(-). However, with the potentially slow movement of water in the subsoil, denitrification and DNRA (0 to 264 mu g N kg super(-1) d super(-1)) together could have completely consumed NO sub(3) super(-) within 0.5 m of entering the riparian zone.

Merr.] growing regions of the United States in 2000. By 2005, the aphids had spread to 23 soybean growing states reaching as far south as Mississippi and Georgia and also north into Ontario, Canada. The objective of this study was to identify new sources of resistance to the SA. Nearly 200 soybean genotypes (cultivars, breeding lines, and plant introductions [PIs]) were screened for resistance to SA in a greenhouse choice test using SA collected in Wooster, OH. Three PIs (PI 243540, PI 567301B, and PI 567324) were identified as resistant while six PIs were identified as moderately resistant. The findings on the three resistant and three of the six moderately resistant PIs were confirmed through further field and greenhouse tests. PI 243540 displayed strong antibiosis resistance such that SA was unable to survive on this PI in a no-choice test. The other two resistant PIs possessed mainly antixenosis type resistance. PI 243540 and PI 567301B were also resistant to the SA collection from Illinois. The aphid resistant PIs identified in this study will be useful in efforts to develop aphid-resistant soybean cultivars.

The effects of three aeration treatments and a control (aeration with cores, continuous-furrow "no-till" disk aeration perpendicular to the slope, slit aeration with tines, and no aeration treatment) on the export of total suspended solids, total Kjeldahl P (TKP), total dissolved P (TDP), dissolved reactive P (DRP), and bioavailable P (BAP) in runoff from grasslands with three manure treatments (broiler litter, dairy slurry, and no manure) were examined before and after simulated compaction by cattle. Plots (0.75 x 2 m) were established on a Cecil soil series with mixed tall fescue (Festuca arundinacea Schreb.)-bermudagrass [Cynodon dactylon (L.) Pers.] vegetation on 8 to 12% slopes. Manures were applied at a target rate of 30 kg P ha super(-1), and simulated rainfall was applied at a rate of 85 mm h super(-1). Although the impact of aeration type on P export varied before and after simulated compaction, overall results indicated that core aeration has the greatest potential for reducing P losses. Export of TKP was reduced by 55%, TDP by 62%, DRP by 61%, total BAP by 54%, and dissolved BAP by 57% on core-aerated plots with applied broiler litter as compared with the control (p < 0.05). Core and no-till disk aeration also showed potential for reducing P export from applied dairy slurry (p < 0.10). Given that Cecil soil is common in pastures receiving broiler litter in the Southern Piedmont, our results indicate that pairing core aeration of these pastures with litter application could have a widespread impact on surface water quality.

Diet modifications such as low-phytate corn (Zea mays L.) have resulted in improved bioavailability of P and reduced manure P content. A field study was conducted to compare in situ availability of N and P at two sites. One site received three annual additions of manure from swine fed low-phytate corn or traditional corn diets or inorganic fertilizer, surface applied to rainfed no-till sorghum [Sorghum bicolor (L.) Moench]. A second site received a one-time application and incorporation of the same nutrient treatments to irrigated corn. Nutrient treatments were applied at rates intended to meet crop N needs. At both sites, an in situ soil core resin bag technique was used to determine available N and P during the growing season. Potentially mineralizable N was 70% of applied N and extractable P was 100% of applied P for manure from both diets. Incorporation of swine slurry reduced potentially mineralizable N to 40% the year of application and 30% the year after application and reduced extractable P to 60% the year of application and 40% the year after application for both diets. Modified diets reduced the P content of the manure but not the availability of N or P.

A quantity of limestone equivalent to 0 and 6720 kg ha super(-1) was surface applied to vegetated 45-cm-deep columns of a Typic Hapludult soil collected from an abandoned Fescue spp. grassland in southern West Virginia. Eighteen weeks after lime application, one, two, or three applications of urine supplying a total of 36, 98, or 177 g m super(-2) of N, respectively, were made. One and two applications of urine increased vegetative growth and decreased the amount of water leaching through the column, but the third addition damaged plants. The three-addition treatment reduced the amount of N taken up by the plants, decreased transpiration, increased leachate volume, and resulted in a 12-fold increase in the amount of N leached from the columns compared with the one-application treatment. Leachate Ca, Mg, and K were increased by urine. Soil pH and extractable Ca and Mg were decreased by urine and increased by limestone, and extractable Al was increased by urine and decreased by limestone applications. Net amounts of N recovered as NH sub(3) gas released to the atmosphere, N taken up into aboveground plant material, NH sub(4) super(+) and NO sub(3) super(-) extracted from soil, and NH sub(4) super(+) and NO sub(3) super(-) in drainage water ranged from 49 to 77% of the amount added. Surface application of limestone alleviated some of the detrimental effects of high rates of urine addition by increasing levels of pH, Ca, and Mg and reducing Al as deep as 28 cm in the profile.

We report on corn (Zea mays L.), soybean [Glycine max (L.) Merr.], and wheat (Triticum aestivum L.) yields at the USDA-ARS Beltsville Farming Systems Project (FSP), a long-term cropping systems trial established in Maryland in 1996 to evaluate the sustainability of organic and conventional grain crop production. The five FSP cropping systems include a conventional no-till corn-soybean-wheat/soybean rotation (NT), a conventional chisel-till corn-soybean-wheat/soybean rotation (CT), a 2-yr organic corn- soybean rotation (Org2), a 3-yr organic corn-soybean-wheat rotation (Org3), and a 4- to 6-yr organic corn-soybean-wheat-hay rotation (Org4+). Average corn grain yield during 9 yr was similar in NT and CT (7.88 and 8.03 Mg ha super(-1), respectively) but yields in Org2, Org3, and Org4+ were, respectively, 41, 31, and 24% less than in CT. Low N availability explained, on average, 73% of yield losses in organic systems relative to CT while weed competition and plant population explained, on average, 23 and 4%, respectively, of these yield losses. The positive relationship between crop rotation length and corn yield among organic systems was related to increasing N availability and decreasing weed abundance with increasing rotation length. Soybean yield averaged 19% lower in the three organic systems (2.88 Mg ha super(-1)) than in the conventional systems (3.57 Mg ha super(- 1)) and weed competition alone accounted for this difference. There were no consistent differences in wheat yield among cropping systems. Crop rotation length and complexity had little impact on soybean and wheat yields among organic systems. Results indicate that supplying adequate N for corn and controlling weeds in both corn and soybean are the biggest challenges to achieving equivalent yields between organic and conventional cropping systems.

The endemic species Olla v-nigrum, Cycloneda munda and Hippodamia convergens were susceptible to B. bassiana Isolate B which was originally isolated from O. v-nigrum and the rate assayed was known to represent the LC sub(50) against O. v-nigrum. However, neither the endemic C. maculata nor the exotic species Harmonia axyridis and Coccinella septempunctata were susceptible to this isolate at this rate. Additionally, all species of endemic and exotic Coccinellidae used in these assays were resistant to B. bassiana strain GHA and BbAR1 at that rate. We discuss the implications of these results in regard to the establishment of exotic species in new habitats.

This study examined how planting date affects the productivity of grass pea (Lathyrus sativus L.) in central Oklahoma. Experimental plots (3 by 20 m, n = 3) were disked and fertilized with 60 kg P sub(2)O sub(5) ha super(-1), and inoculum-treated (Rhizobium leguminosarum) seeds ('AC-Greenfix') were planted at 60 kg ha super(-1) on 15 March, 1 April, and 15 April in 2004, 2005, and 2006. Biomass, N concentration, N accumulation per hectare, and in vitro digestible dry matter (IVDDM) of grass pea forage were determined on samples collected at 7 d of the year (DOY) after planting. Significant (P < 0.05) interactions occurred in response of biomass (DOY x year), N concentration, and IVDDM (DOY x year x planting date), and accumulated N (DOY x year; DOY x planting date). Peak biomass in 2004, 2005, and 2006 was 3900, 5800, and 3500 kg ha super(-1), respectively. Maximum accumulated N related to years was 115 to 157 kg ha super(- 1) between DOY 165 and DOY 195. Peak N accumulation of 125 to 153 kg ha super(-1) occurred between DOY 180 and DOY 210. Grass pea is flexible in response to spring planting dates, indicating that it can be sown as a green manure or forage crop during a 30-d period in the southern Great Plains and still maximize biomass and N accumulation.

At the time of English settlement, this subspecies was abundant throughout Louisiana, the southern two-thirds of Mississippi, eastern Texas, and extreme southern Arkansas. By the 1950s, Louisiana black bears had been extirpated from most of their original range due to habitat destruction and fragmentation and overharvest by hunters (Leigh and Chamberlain 2008). It is believed that only about 100 black bears remained; existing in isolated, extremely rural areas of eastern Louisiana. Bears became so scarce during the 1960s that the Louisiana Department of Wildlife and Fisheries (LDWF) initiated a restocking program using bears captured in Minnesota. The restoration program ultimately was unsuccessful. Small, isolated bear populations continued to hang onto existence, and, in 1992, the U. S. Fish and Wildlife Service (FWS) listed the Louisiana black bear as threatened.

Identification of superior genotypes for improved agronomic characteristics will enhance tuber yield. Seven promising clones from population B potato selections (quantitative resistance to late blight) obtained from the International Potato Center, two genotypes from population A (qualitative resistance) and three control cultivars were evaluated for three cropping seasons at four locations in western Uganda in order to determine performance and yield stability. The additive main effects and multiplicative interactive (AMMI) model was used for the analysis. The analysis of variance of yield data for genotypes x locations, genotypes x seasons and genotypes x locations x seasons was significant (p < 0.05) showing the variable response of genotypes and the need for stability analysis. The AMMI statistical model showed that the most stable genotypes were 392618.250 (B5) and 392127.270 (B6) (high yield) and 392618.256 (B1), 391049.255 (B2) and 392127.256 (B7) (low yield) and had negligible interactions with the environments. Across environments, the ranking of genotypes for tuber yield was not consistent. The clones 381471.18 (A2), 387121.4 (A1) and cultivar Victoria had high average yields, but these yields were below average in a few environments. Selective deployment of cultivars can improve tuber yield in the highland tropics.

The weather model simulations and forecasts are ongoing experimental products from the Experimental Climate Prediction Center at the Scripps Institution of Oceanography. The monthly average Fosberg Fire Weather Index, deduced from the weather simulation, along with the monthly average Keetch-Byram Drought Index and Energy Release Component, were found to be more strongly associated with large fire events on a monthly scale than any of the other stand-alone fire weather or danger indices. These selected indices were used in the spatially explicit probability model to estimate the number of large fire events. Historic probabilities were also estimated using spatially smoothed historic frequencies of large fire events. It was shown that the probability model using four fire danger indices outperformed the historic model, an indication that these indices have some skill. Geographical maps of the estimated monthly wildland fire probabilities, developed using a combination of four indices, were produced for each year and were found to give reasonable matches to actual fire events. This method paves a feasible way to assess the skill of climate forecast outputs, from a dynamical meteorological model, in forecasting the probability of wildland fire severity with known precision.

The purpose of this study was to determine if early immunization against GnRH would induce a long-lasting immune response in fawns, and if it would delay or prevent sexual development. We gave primary and subsequent booster injections of a KLH-GnRH/Freund's vaccine to 6 male and 6 female fawns. This vaccine contained the same active ingredients as GonaCon vaccine, but it contained Freund's adjuvant instead of AdjuVac adjuvant. Two 450- mu g injections were given 1 month apart when fawns were 3 and 4 months of age. Although 1 female fawn produced a multiyear contraceptive response similar to that observed previously in vaccinated adults, the immune response lasted only 1 year in the other 11 fawns. Antibody titers in those 11 fawns declined sharply to near zero during the second and third years after vaccination. Our results indicate that treating 3- to 4-month-old white-tailed deer with the GnRH vaccine did not induce contraception or sterilization, and it did not delay or prevent sexual development. No adverse health effects were apparent in GnRH-treated fawns.

Host and geographic distribution for this parasite, however, remain poorly defined in the region of western North America. Fecal samples collected from Columbia white-tailed deer (O. v. leucurus) in a restricted range endemic to Oregon and Washington, USA, were examined for dorsal-spined larvae characteristic of many protostrongylid nematodes. Multilocus DNA sequence data (internal transcribed spacer 2 and cytochrome c oxidase subunit 1) established the identity and a new record for P. andersoni in a subspecies of white- tailed deer previously unrecognized as hosts. Populations of P. andersoni are now recognized along the basin of the lower Columbia River in Oregon and Washington and from south-central Oregon on the North Umpqua River. Current data indicate a potentially broad zone of sympatry for P. andersoni and Parelaphostrongylus odocoilei in the western region of North America, although these elaphostrongylines seem to be segregated, respectively, in white-tailed deer or in black-tailed and mule deer (Odocoileus hemionus) at temperate latitudes. The geographic range for P. andersoni in white- tailed deer is extended substantially to the west of the currently defined limit in North America, and we confirm an apparently extensive range for this elpahostrongyline. These observations are explored in the broader context of host and geographic associations for P. andersoni and related elaphostrongylines in North American cervids.

It is caused by fungal species belonging to the genus Fusarium and the mycotoxins they produce. Although it has proved difficult to combat this disease, one strategy that has been examined is the introduction of an indigenous fungal protective gene into cereals such as wheat barley and rice. Thus far the gene of choice has been tri101 whose gene product catalyzes the transfer of an acetyl group from acetyl coenzyme A to the C3 hydroxyl moiety of several trichothecene mycotoxins. In vitro this has been shown to reduce the toxicity of the toxins by similar to 100-fold but has demonstrated limited resistance to FHB in transgenic cereal. To understand the molecular basis for the differences between in vitro and in vivo resistance the three-dimensional structures and kinetic properties of two TRI101 orthologs isolated from Fusarium sporotrichioides and Fusarium graminearum have been determined. The kinetic results reveal important differences in activity of these enzymes toward B-type trichothecenes such as deoxynivalenol. These differences in activity can be explained in part by the three-dimensional structures for the ternary complexes for both of these enzymes with coenzyme A and trichothecene mycotoxins. The structural and kinetic results together emphasize that the choice of an enzymatic resistance gene in transgenic crop protection strategies must take into account the kinetic profile of the selected protein.

We examined the effect of predation risk on foraging A. uniparens in outdoor enclosures, observing their behavior in the presence and absence of the predatory lizard Gambelia wislizenii. Predator presence led to changes in activity patterns and foraging behavior. When predators were present, A. uniparens reduced both the proportion of time active and time moving, shifted activity periods, reduced their movement rate, and changed the duration of moves. There were no apparent changes in digging effort, but the likelihood of successfully digging for food decreased when a predator was present.

This paper reviews the research on the symbiotic associations of bacteria with plant-parasitic nematodes and the implication for biological control of these nematodes. Emphasis is given to Pasteuria spp. (Firmicutes), the best characterized endosymbiont of plant-parasitic nematodes with demonstrated potential for use as biological control agents.

Hara, is a common disease of soybean [Glycine max (L.) Merr.] in most soybean- growing countries of the world. Significant yield losses of soybean (10-60%) have been attributed to FLS under hot and humid growing conditions. The FLS in the southern United States has been kept under control by planting resistant cultivars. Cercospora sojina is a dynamic pathogen with extensive virulence or race diversity. The current number of C. sojina isolates at the University of Georgia collection is 93. Assigning race designations to this large number of isolates has been difficult because of the lack of a well-defined set of differentials. To facilitate future studies of the genetics of soybean resistance to FLS and the identification and comparison of existing and future races of C. sojina, we have reassessed both the soybean differentials and the C. sojina races. Based on the reactions of 93 isolates of C. sojina on 38 putative soybean differentials, we propose a core set of 12 differentials and 11 races that represent the major diversity among the 93 C. sojina isolates. The definition of these 12 differentials and 11 races should provide the foundation for the identification and comparison of additional soybean resistance genes and new races of C. sojina.

Although original expectations were that tours would be composed of general members of the public, individual tour groups ultimately were much more specialised, with tours made up of individuals from five distinct groups including foresters, environmentalists, entomologists, the Natural Resource Conservation Service, teachers, and high school or undergraduate students. This proved fortuitous as most studies of 'public' perceptions to date have been of general members of the public and little work has been done assessing the views of groups who may have more specific knowledge or interest in fuels treatments. Such assessment is perhaps long overdue given the importance of understanding characteristics of different audience segments in developing effective outreach programs. Analysis showed that group membership was in fact the key element in differences in survey responses with significant differences found between groups on overall acceptability of treatments, treatment preferences based on different land ownership and management types, and which variables were most important in determining treatment preferences.

On the other hand, much less is known about how fire affects the thermal properties and the long-term thermal regime of soils. Such knowledge is important for understanding the nature of the soil's post-fire recovery because plant roots and soil microbes will have to adapt to any changes in the day-to-day thermal regime. This study, which was carried out at Manitou Experimental Forest (a semiarid site in the Rocky Mountains of central Colorado, USA), examines three aspects of how fire can affect the long-term (post-fire) thermal energy flow in soils. First, observational evidence is presented that prescribed burns can alter the thermal conductivity of soils to a depth of at least 0.2 m without altering its bulk density. Second, data are presented on the thermal properties of ash. (Such data are necessary for understanding and modeling the impact any remaining post-fire ash layer might have on the daily and seasonal flow of thermal energy through the soil.) Third, observational data are presented on the long-term effects that prescribed burns can have on soil surface temperatures. In an effort to quantify long-term changes in the soil temperatures and heat fluxes resulting from fire this study concludes by developing and using an analytical model of the daily and annual cycles of soil heating and cooling, which incorporates observed (linear variation of) vertical structure of the soil thermal properties and observed changes in the surface temperatures, to synthesise these fire-induced effects. Modeling results suggest that under the dry soil conditions, typical of the experimental forest, the amplitudes of the daily and seasonal cycles of soil heating/cooling in the fire-affected soils will greatly exceed those in the soils unaffected by fire for several months to years following the fire and that these effects propagate to depths exceeding one metre.

SR1 (Petite Havana) was evaluated as a host for the bioassay of Xylella fastidiosa strains. Plant growing conditions and inoculation methods were optimized to enhance symptom expression 4 to 6 weeks post inoculation. Tobacco plants were inoculated with X. fastidiosa strains associated with almond leaf scorch disease (ALSD) and Pierce's disease (PD) of grapevine in California. All PD strains and the ALSD strain Dixon caused characteristic leaf scorch symptoms, whereas two other ALSD-associated strains (M12 and M23) caused severe leaf chlorosis followed by necrosis, leaf death, and drooping of older leaves. Symptoms began to develop 10 to 14 days post inoculation and proceeded to resemble those of X. fastidiosa-infected grape and almond. The presence of X. fastidiosa in affected plants was confirmed by reisolation of the pathogen, enzyme-linked immunosorbent assay, quantitative polymerase chain reaction (QPCR), and observation of X. fastidiosa cells by transmission and scanning electron microscopy, as well as by confocal laser scanning microscopy, in the xylem cells of inoculated plants. The pathogenicity of selected reisolated strains was confirmed by inoculation of grape plants in the greenhouse. The average levels of X. fastidiosa cells/g of tissue, estimated by QPCR, were higher for PD strains than for ALSD strains and reflected the relative titers of these strains in economic hosts. No symptoms were observed and bacteria were not detected in untreated tobacco or in tobacco inoculated with Xanthomonas campestris pv. campestris or water. Symptoms induced by Xylella fastidiosa in this bioassay were fully expressed within 2 months following inoculation. The described bioassay, under optimized environmental conditions, provides a useful system for studying X. fastidiosa strains (e.g., confirmation of pathogenicity and differentiation of PD and ALSD pathotypes) and for investigating X. fastidiosa-host interactions. N. tabacum cv. SR1 tobacco was a better bioassay host for X. fastidiosa than N. tabacum cvs. Havana, RP1, and TNN described previously.

Selected malodorous compounds were measured by the use of equilibrium samplers consisting of submersible stir plates and stir bar sorbtive sampling with polydimethylsiloxane-coated magnetic stir bars. During the same period, air and water temperatures, suspended solids, total organic carbon and nitrogen content, and wastewater pH were recorded. Concentrations of malodorous compounds were higher at the surface of the lagoon than at the middle or bottom of the lagoon. Skatole concentration, for instance, averaged 54, 24, and 38 mu g L super(-1) near the surface, in the middle, and at the lowest sampling depths, respectively. While the lagoon was being pumped down during field application of wastewater, concentrations of malodorous compounds fluctuated widely, increased 16-fold as compared with the sampling period before pumping, and continued to increase as fall progressed and temperatures cooled. Suspended solids, volatile suspended solids, and total organic carbon increased near the bottom of the lagoon during this same period. The increases in the concentrations of malodorous compounds in the wastewater during the fall could have been due to a combination of several factors. These factors include reduced degradation by lagoon bacteria, less wind stripping of volatile compounds from the lagoon surface due to lowering of the lagoon surface after crop application, and/or reduced evaporation of malodorous compounds due to falling temperatures.

Nesting splits the sequence structure of TEs and makes annotation of repetitive areas challenging. We present TEnest, a repeat identification and display tool made specifically for highly repetitive genomes. TEnest identifies repetitive sequences and reconstructs separated sections to provide full-length repeats and, for long-terminal repeat (LTR) retrotransposons, calculates age since insertion based on LTR divergence. TEnest provides a chronological insertion display to give an accurate visual representation of TE integration history showing timeline, location, and families of each TE identified, thus creating a framework from which evolutionary comparisons can be made among various regions of the genome. A database of repeats has been developed for maize (Zea mays), rice (Oryza sativa), wheat (Triticum aestivum), and barley (Hordeum vulgare) to illustrate the potential of TEnest software. All currently finished maize bacterial artificial chromosomes totaling 29.3 Mb were analyzed with TEnest to provide a characterization of the repeat insertions. Sixty-seven percent of the maize genome was found to be made up of TEs; of these, 95% are LTR retrotransposons. The rate of solo LTR formation is shown to be dissimilar across retrotransposon families. Phylogenetic analysis of TE families reveals specific events of extreme TE proliferation, which may explain the high quantities of certain TE families found throughout the maize genome. The TEnest software package is available for use on PlantGDB under the tools section (http://www.plantgdb.org/prj/TE_nest/TE_nest.html); the source code is available from http://wiselab.org.

Host plant resistance is thought to be an efficient and economical method of control. The objective of the present study was to identify novel sources of tan spot and SNB resistance in wheat genotypes derived from the crosses between wheat and alien species. Evaluations were conducted at the seedling stage in a growth chamber with 100% relative humidity. For each genotype, three replications were used for each disease. Among the 199 wheat-alien species derivatives evaluated, 65 exhibited resistance to tan spot and 30 showed resistance to SNB similar to BR34, a Brazilian wheat line used as the resistant control. Eleven derivatives were resistant to both diseases. Reactions of the derivatives and their respective wheat parents to tan spot and SNB suggest that resistance genes in the derivatives are derived from alien species. These derivatives can serve as desirable bridges for introgression of resistance genes from alien species to cultivated wheat, and could contribute novel and effective tan spot and SNB resistance to wheat breeding.

It has often been characterized by utilizing a combination of chemical dispersion of the soil followed by physical separation. We fractionated soil samples under continuous corn (Zea mays L.) rotations at four long-term sites in the Corn Belt to determine the concentration of C and N associated with soil fractions (light fraction [LF], particulate organic matter [POM], silt size, clay size, and Bradford reactive soil protein [BRSP]) and to identify the change in C concentration and {delta} super(13)C signal of each fraction using laboratory incubations. Light fractions comprised 3 to 5% of the soil organic carbon (SOC), with no significant difference between conventional tillage (CT) and no-till (NT) treatments. The POM fraction accounted for 5 to 11% of the SOC in the soils with >30% clay and 17 to 23% for the soils with <20% clay. The clay-size fraction contained the highest proportion of SOC. Measurement of super(13)C during long-term incubation showed that the average mean residence time (MRT) of corn-derived C in the LF was 3.5 yr, whereas the POM fractions ranged from 6 to 12 yr. The super(13)C changes during incubation show that both fractions consist of a mixture of active and resistant materials, with movement between fractions. The BRSP has long MRTs except in the NT Hoytville soil. Measurement of the dyna mics of these fractions provides a basis for C models to test the impacts of land use and management on C sequestration.

AN - 20812963; 8178964 AB - The rise in atmospheric CO sub(2) concentration coupled with its direct, often positive, effect on the growth of plants raises the question of the response of invasive plants to elevated atmospheric CO sub(2) levels. Response of two invasive weeds [purple nutsedge (Cyperus rotundus L.) and yellow nutsedge (Cyperus esculentus L.)] to CO sub(2) enrichment was tested. Plants were exposed to ambient (375 mu mol mol super(-1)) or elevated CO sub(2) (ambient + 200 mu mol mol super(-1)) for 71 d in open top chambers. Photosynthetic rate did not differ between CO sub(2) treatments for either species. Conductance was lower in purple nutsedge and tended to be lower in yellow nutsedge. Purple nutsedge had higher instantaneous water use efficiency; a similar trend was noted for yellow nutsedge. Purple nutsedge had greater leaf area, root length and numbers of tubers and tended to have more tillers under high CO sub(2). In yellow nutsedge, only tuber number increased under CO sub(2) enrichment. Leaf dry weight was greater for both species when grown under elevated CO sub(2). Only purple nutsedge made seed heads; CO sub(2) level did not change seed head dry weight. Root dry weight increased under the high CO sub(2) treatment for purple nutsedge only, but tuber dry weight increased for both. Total dry weight of both species increased at elevated CO sub(2). Purple nutsedge (under elevated CO sub(2)) tended to increase allocation belowground, which led to greater root-to-shoot ratio (R:S); R:S of yellow nutsedge was unaffected by CO sub(2) enrichment. Findings suggest both species, purple more than yellow nutsedge, may be more invasive in a future high-CO sub(2) world.

In order to survey the distribution of different genotypes within an area, free-range chickens act as a good model species. In this study 85 chickens were used to investigate the prevalence, genotype and mouse virulence of T. gondii in Kampala, Uganda. Antibodies were detected in 40 chickens, of which 20 had MAT-titres of 1:20 or higher and were also positive by PCR. Genotyping of 5 loci (SAG1, SAG2, SAG3, BTUB and GRA6) showed that 6 strains belonged to genotype I, 8 to Type II and 1 to Type III. Five chickens had multiple infections; 3 individuals with Type I plus Type II and a further 2 harbouring Types I, II and III. Isolates were obtained from 9 chickens via bioassay in mice, 6 were Type II strains and 3 were from animals with mixed infection. This is the first set of African T. gondii strains to be genotyped at multiple loci and in addition to the 3 predominant lineages we found a small number of new polymorphisms and a high frequency of multiple infections.

In this study, a set of Landsat Thematic Mapper (TM)-based linear logistic models were developed for mapping tillage practices and verified with an independent dataset. For data collection purposes, 35 and 41 commercial fields were randomly selected in Moore and Ochiltree counties, respectively, in the Texas Panhandle. Tillage survey was planned and conducted to coincide with Landsat 5 satellite overpasses during the 2005 planting season and two TM scenes were acquired. Using the Moore County dataset, seven logistic regression models were developed and these were evaluated with the data collected from Ochiltree County. The overall classification accuracy of the models varied from 86% to 91% with the Moore County dataset. These models were evaluated against independent Ochiltree County dataset and resulted in somewhat less accurate (classification accuracy of 67-85%) but still useful results. Analysis of these results indicates that logistic regression models that have indices derived from the combination of TM band 5 with bands 4 or 6 may provide consistent and acceptably accurate results when they are applied in the same geographic region.

Later smoke events in the southeastern metropolitan areas of the United States caused by the Georgia-Florida wild forest fires further magnified the significance of forest fire emissions and the benefits of being able to accurately predict such occurrences. By using preburning information, we utilize an operational forecasting system to simulate the potential air quality impacts from two large February 28th fires. Our "forecast" predicts that the scheduled prescribed fires would have resulted in over 1 million Atlanta residents being potentially exposed to fine particle matter (PM sub(2.5)) levels of 35 kg m super(-3) or higher from 4 p.m. to midnight. The simulated peak 1 h PM sub(2.5) concentration is about 121 kg m super(-3). Our study suggests that the current air quality forecasting technology can be a useful tool for helping the management of fire activities to protect public health. With postburning information, our "hindcast" predictions improved significantly on timing and location and slightly on peak values. "Hindcast" simulations also indicated that additional isoprenoid emissions from pine species temporarily triggered by the fire could induce rapid ozone and secondary organic aerosol formation during late winter. Results from this study suggest that fire induced biogenic volatile organic compounds emissions missing from current fire emissions estimate should be included in the future.

Conventionally, isolation of these bacteria has been from soil and sporadically from dead insects. A simplified approach for isolating insecticidal bacteria from soil using the target insect as the selective agent was employed in this study. Instead of isolating single strains of bacteria from soil and testing each individual strain for insect toxicity, mixtures of bacteria present in each soil sample were tested together directly for toxicity using Manduca sexta (Linnaeus) (Lepidoptera: Sphingidae) as a model insect. Thirty-five soil suspensions or bacterial suspensions of the 40 suspensions tested killed at least one M. sexta larva. All but one bacterial culture isolated from dead larvae and retested for toxicity, killed at least one M. sexta larva. Nineteen bacterial strains isolated from larvae killed in the first test, were identical to the bacteria fed to the retested larvae. Of the 19 strains isolated, 14 were identified by 16S rDNA sequencing as belonging to the Bacillus cereus group including three strains that formed crystals that were identified as B. thuringiensis. Of the three other spore-forming strains, two were identified as psychrotrophic B. weihenstephanensis and the third as Lysinibacillus fusiformis. Two others were identified as Enterococcus faecalis. This approach, microbial combinatorics, reduces the number of insects necessary for toxicity screening and associated time and resources compared to conventional methods that first isolate bacteria and then individually test for toxicity as well as a means of discovery of new pathogens using the insect as the selective agent.

This study determined the water used, water use efficiency (WUE), and soil water depletion of forage (n = 3) and grain (n = 1) soybean [Glycine max (L.) Merr.] cultivars on silt loam soils following winter wheat harvest during the 2003 to 2005 summer growing seasons. Interactions (P 0.10). All cultivars used 2.0 to 2.5 times more water in 2004 and 2005 than 2003 (driest year). Forage production in 2003 (3034 kg ha super(-1)) was 55% lower than in 2004 and 2005. Higher WUE (kg ha super(-1) mm super(-1)) was recorded in 2004 (16.0) than 2003 (13.2) or 2005 (10.9). Incorporating soybean into fallow periods following wheat generally limits the amount of soil water available for fall production of wheat forage in the SGP.

The dominant soil in this region is a Pullman clay loam (fine, mixed, superactive, thermic Torrertic Paleustoll), which features dense subsoil layers that limit infiltration and root proliferation. Deep ( similar to 0.7 m) plowing may eliminate these layers, but the duration of treatment efficacy must be sufficient to recoup costs. Our objective was to quantify the long-term effects of deep plowing on soil bulk density (BD), penetration resistance (PR), ponded infiltration, and crop yield. In fall 1971, paired 24- by 460-m level conservation bench terrace plots at the USDA-ARS Conservation and Production Research Laboratory, Bushland, TX (35 degree 11' N, 102 degree 5' W) were moldboard plowed to 0.7 m or untreated and, subsequently, maintained with conventional sweep tillage. Grain sorghum [Sorghum bicolor (L.) Moench] was grown intermittently during the next 34 yr for 15 paired yield comparisons. Compared with the control, deep plowing significantly decreased BD and PR and increased water infiltration. Long-term mean grain yield of 2.86 Mg ha super(-1) with deep plowing was greater (P < 0.05) than the 2.61 Mg ha super(-1) yield in control plots. Approximately 89% of the 15-yr 3.75 Mg ha super(-1) cumulative yield increase with deep plowing occurred during 4 yr with large early growing season rains. We attributed this yield increase with deep plowing to greater internal drainage that reduced crop injury during infrequent floods and not greater root growth through the dense subsoil. Thirty years after deep plowing, high water intake suggests that flow-limiting subsoil layers had not yet redeveloped. The sustained deep-plowing benefit extends the period to recoup the 1971 plowing costs of US$160 ha super(-1).

To understand the long-term effects of a single coapplication and the short-term impacts of a repeated coapplication on soil P inorganic and organic transformations, 7.5- by 15-m plots with treatments of three different WTR rates with a single biosolids rate (5, 10, and 21 Mg WTR ha super(-1) and 10 Mg biosolids ha super(-1)) surface coapplied once in 1991 or surface reapplied in 2002 were utilized. Soils from the 0- to 5-cm depth were collected in 2003 and 2004 and were sequentially fractionated for inorganic and organic P (P sub(o)). Inorganic P fractionation determined (i) soluble and loosely bound, (ii) Al-bound, (iii) Fe-bound, (iv) occluded, and (v) Ca-bound P, while organic P fractionation determined (i) labile, (ii) biomass, (iii) moderately labile, (iv) fulvic acid, (v) humic acid, and (vi) nonlabile associated P sub(o). Pathway analysis showed that humic, fulvic, and nonlabile P sub(o) did not play a role in P transformations. Biomass P sub(o) and moderately labile P sub(o) contributed to the transitory labile P sub(o) pool. Labile P sub(o) was a P source for Fe-bound and WTR-bound inorganic phases, with the Fe-bound phase transitory to the occluded P sink. The Al-bound phase additionally contributed to the occluded P sink. The Ca- bound phase weathered and released P to both the Fe-bound and WTR-bound P phases. Overall, the WTR fraction, even 13 yr after the initial application, acted as the major stable P sink.

Though C. fagacearum has received much research attention, the origin of the fungus is unknown. The pathogen may have been endemic at a low incidence until increased disturbances, changes in land use, and forest management created conditions favorable for disease epidemics. The host genus Quercus contains some relatively resistant species native to the United States, further supporting the hypothesis that the pathogen is native in origin. However, there are also many common, highly susceptible Quercus species--a characteristic typical of introduced pathogens. Most convincingly, studies have shown that the known populations of C. fagacearum have experienced a severe genetic bottleneck that can only be explained by a single introduction. The weight of evidence indicates that C. fagacearum is an introduced pathogen, with possible origins in Central or South America, or Mexico.

During the 2-yr study, we captured 37,191 Coleoptera with baited multiple-funnel traps and pipe traps, comprising 20 families and 122 species that were used for our analysis. Saproxylic beetle numbers increased greatly from the first year to the second year on all treatments. Species richness and total abundance of Coleoptera were not significantly affected by the treatments, but several families (e.g., Elateridae, Cleridae, Trogositi-dae, Scolytidae) were significantly more abundant on treated plots. Abundances of many species, including various species of Scolytidae were significantly affected by the treatments. However, these scolytids (Hylastes salebrosus Eichoff, Ips grandicollis Eichoff, Xyloborinus saxeseni Ratzburg, Xyleborus sp., Xyleborus atratus Eichoff) did not respond in the same way to the treatments. Likewise, other Coleoptera such as Pityophagus sp. (Nitidulidae), Hylobius pales Herbst (Curculionidae), and Xylotrechus sagittatus Germar (Cerambycidae) also varied in their responses to the treatments. Species richness was not significantly different for the spring 2003 trapping seasons, but the fall 2003 sample had a higher number of species on mechanical shrub removal only and mechanical shrub removal plus prescribed burning plots compared with controls. Linear regression analysis suggests that increased dead wood caused by hot fires on mechanical plus burn and burn only treatments resulted in increases among various Coleoptera families and species. We saw no evidence that the treatments negatively impacted saproylic species and in most cases they benefited from the disturbances.

Here we demonstrate that these diel fluctuations can be used to investigate both streamflow generation and network routing. We treat evapo-transpiration (ET) as a distributed impulse function in an advection model and analyze the effect of ET on diel fluctuations in discharge. We show that when flow velocity is high during high baseflow, discharge fluctuations tend to be in phase and constructive interference reinforces ET-generated signals resulting in strong diel fluctuations measured at a gauging station at the mouth of the watershed. As flow velocity slows with baseflow recession, ET-generated signals are increasingly out of phase so that fluctuations in discharge are masked by destructive interference. These results demonstrate that naturally produced fluctuations in discharge constitute discrete impulse functions that can be used to analyze eco- hydrologic behavior of whole-watersheds during baseflow periods.

Although the USA spends billions of dollars annually on introduced species research, monitoring and control efforts, only a limited number of government agencies or private institutions are able to provide definitive reports on more than a handful of these species at a national scale. Research on invasive species is only of marginal practical value if the information cannot be succinctly and effectively transmitted to those who determine the management policies, budgets and objectives. To remedy this situation, a national-scale approach for monitoring established non-native species has been developed under the auspices of the Heinz Center as part of 'The State of the Nation's Ecosystems' project. This paper specifically describes the strategies for reporting on indicators for non-native vertebrate species developed through inputs by experts from academia, industry, environmental organisations and government.

In 1991, the Okanogan-Wenatchee National Forest began to apply long-term management techniques to mitigate post-settlement changes in ponderosa pine forests. We used a randomized complete block design with a linear regression component to analyze post-fire responses of the vegetation. Thinning and burning had little effect on the canopy layer of ponderosa pine, western larch, and Douglas-fir, but small grand fir trees, and nearly half of the saplings of all species, were killed. Shrubs in the middle forest layer were top-killed, but resprouted during the first post-fire growing season, and increased dramatically after 3 yr and 9 yr. Frequency and cover maintained or increased for species in the lower forest layer in post-fire years 1, 3, and 9. The thinning and fire treatments reduced the middle layer of small trees and shrubs in the first post-fire year, but by the third and ninth post-fire years tree seedlings, especially grand fir and ponderosa pine, and small shrubs were abundant in the understory. Thinning trees and removing excess fuels, coupled with low intensity fall prescribed burns, offers a promising management strategy for restoring the pre-settlement structure of the ponderosa pine/pinegrass community in Beehive Forest.

Our objective was to develop and evaluate a hybrid procedure to estimate drainage, infiltration, and evaporation based on changes in plot-scale soil water storage on a Pullman clay loam. Soil water contents were monitored in 2005 at 0.5-h intervals on 12 plots instrumented with time-domain reflectometry probes at 0.05, 0.1, 0.15, 0.2, and 0.3 m depths, and weekly using a neutron moisture meter to a depth of 2.3 m in 0.2-m increments. During periods in August 2005 when either a plane of zero flux existed or when a wetting front penetrated into an upper soil layer at similar to 0.24 m, changes in soil water storage were used to iteratively fit hydraulic parameters to estimate soil water fluxes into and out of the control volume. Predicted hydraulic conductivities were not significantly different (p = 0.471) from hydraulic conductivities calculated using the iterative method during three other months in 2005 and yielded drainage rates that differed by less than 0.05 mm d super(-1) as compared to calculated changes in storage below the plane of zero flux. By considering the delayed response of water content measurements to precipitation inputs, cumulative infiltration and evaporation throughout a month with 103-mm precipitation could be estimated from the measured changes in soil water storage with expected uncertainties of plus or minus 5 mm. The proposed procedure permits the indirect estimation of soil water balance components useful for comparing plot-scale treatments and overcomes some of the difficulties associated with weighing lysimeter and meterological approaches.

Biological bioremediation techniques typically rely on the immobilization of TNT reduction products rather than on TNT mineralization. We hypothesized that sheep ruminal microbes would be suitable for TNT destruction after phytoremediation of TNT-contaminated soils by cool-season grasses. Therefore we investigated the fate of [ super(14)C]TNT in ruminating sheep to determine the utility of ruminant animals as a portion of the bioremediation process. Three wether sheep were dosed with 35.5 mg each of dietary unlabeled TNT for 21 consecutive days. On day 22 sheep (41.9 +/- 3.0 kg) were orally dosed with 35.5 mg of [ super(14)C]TNT (129 mu Ci; 99.1% radiochemical purity). Blood, urine, and feces were collected at regular intervals for 72 h. At slaughter, tissues were quantitatively collected. Tissues and blood were analyzed for total radioactive residues (TRR); excreta were analyzed for TRR, bound residues, and TNT metabolites. Plasma radioactivity peaked within 1 h of dosing and was essentially depleted within 18 h. Approximately 76% of the radiocarbon was excreted in feces, 17% in urine, with 5% being retained in the gastrointestinal tract and 1% retained in tissues. Parent TNT, dinitroamino metabolites, and diaminonitro metabolites were not detected in excreta. Ruminal and fecal radioactivity was essentially nonextractable using ethyl acetate, acetone, and methanol; covalent binding of fecal radioactive residues was evenly distributed among extractable organic molecules (i.e., soluble organic matter, soluble carbohydrate, protein, lipid, and nucleic acid fractions) and undigested fibers (cellulose, hemicellulose, and lignin). This study demonstrated that TNT reduction within the ruminant gastrointestinal tract leads to substantial immobilization of residues to organic matter, a fate similar to TNT in other strongly reducing environments.

However, it remains unclear if atmospheric CO sub(2) effects on plant biomass super(15)N are driven by CO sub(2)-induced changes in soil moisture. We tested whether super(15)N abundance (expressed as delta super(15)N) in plant biomass would increase with increasing soil moisture content at two atmospheric CO sub(2) levels. In a greenhouse experiment we grew sunflower (Helianthus annuus) at ambient and elevated CO sub(2) (760 ppm) with three soil moisture levels maintained at 45, 65, and 85% of field capacity, thereby eliminating potential CO sub(2)-induced soil moisture effects. The delta super(15)N value of total plant biomass increased significantly with increased soil moisture content at both CO sub(2) levels, possibly due to increased uptake of super(15)N-rich organic N. Although not adequately replicated, plant biomass delta super(15)N was lower under elevated than under ambient CO sub(2) after adjusting for plant N uptake effects. Thus, increases in soil moisture can increase plant biomass delta super(15)N, while elevated CO sub(2) can decrease plant biomass delta super(15)N other than by modifying soil moisture.

However early reports suggest that several species are capable of parasitizing Aspergillus and sporulating on the conidial heads of the host. More recently Eupenicillium ochrosalmoneum and E. cinnamopurpureum, both with Penicillium anamorphs, have been observed sporulating on the heads of Aspergillus species belonging to section Flavi during the colonization of peanut seeds. Little is known about the host specificity underlying these Aspergillus-Penicillium associations. In this study Aspergillus species representing nine taxonomic sections were paired in culture with E. ochrosalmoneum, E. cinnamopurpureum and two unnamed Penicillium species. Eupenicillium ochrosalmoneum, E. cinnamopurpureum and Penicillium sp. 1 sporulated predominantly on the heads of section Flavi species. In contrast Penicillium sp. 2 was restricted to the heads of section Nigri species. All species spread across Aspergillus colonies by means of aerial hyphae that grew from head to head. Additional studies are required to clarify whether Eupenicillium and Penicillium species are parasitic or simply epibiotic on their hosts.

This study examined how adding chicory to pasture mixtures affected forage yield, root growth, and soil moisture extraction under drought. The experiment was planted in August 2002. Movable rainout shelters were used to control water application in the field. Adding chicory to orchardgrass (Dactylis glomerata L.)-white clover (Trifolium repens L.) or perennial ryegrass (Lolium perenne L.)-white clover mixtures increased drought tolerance in 2003 when chicory constituted 24 to 39% of harvested forage biomass. Chicory mortality was high, decreasing from 39% of harvested forage yield under drought stress in early summer 2003 to 9% in late summer 2004. Improved yield under drought stress was not observed in 2004 when chicory constituted only 9 to 16% of the mixture. The three-species mixtures in 2003 had greater root counts than the two-species mixtures at soil depths below about 70 cm under well-watered conditions, but a greater proliferation of roots at depths below 70 cm was observed for the two-species mixture under drought stress. Both mixtures appeared capable of nighttime transfer of soil water from deep to shallow soil layers, thereby improving water availability to shallow roots. However, improved drought tolerance of the three-species mixture was probably related to improved water use efficiency rather than to greater access to and extraction of deep soil moisture.

Lower P solubility in litter is generally attributed to aluminum-phosphate complex formation. However, recent studies suggest that alum additions to poultry litter may influence organic P mineralization. Therefore, alum-treated and untreated litters were incubated for 93 d to assess organic P transformations during simulated storage. A 62-d soil incubation was also conducted to determine the fate of incorporated litter organic P, which included alum-treated litter, untreated litter, KH sub(2)PO sub(4) applied at 60 mg P kg super(-1) of soil, and an unamended control. Liquid-state super(31)P nuclear magnetic resonance indicated that phytic acid was the only organic P compound present, accounting for 50 and 45% of the total P in untreated and alum-treated litters, respectively, before incubation and declined to 9 and 37% after 93 d of storage-simulating incubation. Sequential fractionation of litters showed that alum addition to litter transformed 30% of the organic P from the 1.0 mol L super(-1) HCl to the 0.1 mol L super(-1) NaOH extractable fraction and that both organic P fractions were more persistent in alum-treated litter compared with untreated litter. The soil incubation revealed that 0.1 mol L super(-1) NaOH-extractable organic P was more recalcitrant after mixing than was the 1.0 mol L super(-1) HCl- extractable organic P. Thus, adding alum to litter inhibits organic P mineralization during storage and promotes the formation of alkaline extractable organic P that sustains lower P solubility in the soil environment.

Moench.], KFS2021, which visually exhibits an absence of white fluffy epicuticular wax in leaf and sheath, was characterized using a combination of genetic and physiological approaches. Study of the phenotypic segregation for the bloomless trait in F sub(2) and F sub(2:3) populations from a cross between KFS2021 and BTx623 (a cultivar with bloom showing profuse deposition of white epicuticular wax) suggests that bloomless is controlled by a single nuclear recessive gene. The bloomless parent (KFS2021) and F sub(2) individuals had lower frequency of guttation, leakier epidermal layer (based on percentage of chlorophyll leaching), and higher rate of seedling water loss than the BTx623 and F sub(2) bloom individuals. Bloomless F sub(2) individuals showed 3- to 6- fold higher nighttime transpiration rates relative to F sub(2) bloom individuals based on nighttime conductance. Correlation analysis showed significant negative associations between leaf epicuticular wax load with epidermal permeability and nighttime conductance, which indicate the important role of epicuticular wax in these traits. These results suggest that epicuticular wax may enhance water use efficiency of sorghum by regulating nighttime water loss.

The method used EPA (U.S. Environmental Protection Agency) worst case water (WCW) in 96-well plates. The WCW provided a consistent and relatively simple defined turbid aqueous matrix, high in total organic carbon (TOC) and total dissolved salts (TDS), to simulate swine lagoon effluent, without the inconvenience of malodor and confounding effects from other biological factors. The WCW was originally defined to simulate high turbidity and organic matter in water for testing point-of-use filtration devices. Use of WCW to simulate lagoon effluent for phage testing is a new and innovative application of this matrix. Control of physical and chemical parameters (TOC, TDS, turbidity, temperature, and pH) allowed precise evaluation of microbiological parameters (Salmonella and phages). In a typical application, wells containing WCW were loaded with Salmonella enterica susp. enterica serovar Typhimurium (ATCC14028) and treated with phages alone and in cocktail combinations. Mean Salmonella inactivation rates (k, where the lower the value, the greater the inactivation) of phage treatments ranged from - 0.32 to -1.60 versus -0.004 for Salmonella controls. Mean log sub(10) reductions (the lower the value, the greater the reduction) of Salmonella phage treatments were -1.60 for phage PR04-1, -2.14 for phage PR37-96, and - 2.14 for both phages in a sequential cocktail, versus -0.08 for Salmonella controls. The WCW microcosm system was an effective tool for evaluating the biocontrol potential of Salmonella phages.

Our objectives were to determine: (1) leaf and stem biomass components, (2) nutritive value [in vitro dry matter digestibility (IVDMD), total nonstructural carbohydrate (TNC), N, and N digestibility] of leaves for animal browse, (3) concentration of the secondary metabolites robinin and mimosine, and (4) in vitro leaf and bark toxicity for black locust (Robinia pseudoacacia L.) and mimosa (Albizia julibrissin Durz.), respectively, pollarded at 50 cm in Arkansas, USA. Black locust exceeded mimosa for every yield component (leaf mass tree super(-1), leaves shoot super(-1), shoots tree super(-1), shoot mass tree super(-1), stem basal area, and biomass tree super(-1)) except mass leaf super(-1). Projected yields were 1,900 and 1,600 kg leaves ha super(-1) for black locust and mimosa, respectively, assuming a population of 12,300 trees ha super(-1). Mimosa leaves had greater IVDMD, TNC, and N digestibility than black locust. Mimosa leaves exceeded the nutritional N requirements of growing cattle (Bos taurus L.) and goats (Capra hircus L.), but protein supplementation would be needed for growing goats grazing black locust leaves. Tissue concentrations of secondary metabolites robinin and mimosine were below detectable limits in black locust and mimosa, respectively. The extract of black locust bark, but not leaves, was toxic to bioassayed African green monkey (Cercopithecus aethiops L.) cells. Either black locust or mimosa could provide moderate quantities of high quality, rotationally grazed forage for goats during summer months when herbaceous forage may in short supply.

They bind and destabilize some AU-rich element-containing mRNAs such as tumor necrosis factor mRNA. In this study, recombinant ZFP36L1/TIS11B (a TTP homologue) was overexpressed in E. coli, purified, and used for polyclonal antibody production in rabbits. The antiserum recognized nanograms of the antigen on immunoblots. This antiserum and another antiserum developed against recombinant mouse TTP were used to detect ZFP36L1 and TTP in mouse 3T3-L1 adipocytes and RAW264.7 macrophages. Immunoblotting showed that ZFP36L1 was stably expressed with a size corresponding to the lower mass size of ZFP36L1 expressed in transfected human embryonic kidney 293 cells, but TTP was induced by cinnamon extract and not by lipopolysaccharide (LPS) in adipocytes. In contrast, ZFP36L1 was undetectable, but TTP was strongly induced in LPS-stimulated RAW cells. Quantitative real-time polymerase chain reaction confirmed the higher levels of ZFP36L1 mRNA in adipocytes and TTP mRNA in RAW cells. Low levels of ZFP36L1 expression were also confirmed by Northern blotting in mouse embryonic fibroblasts. These results demonstrate that ZFP36L1 antiserum is useful in the detection of this protein and that TTP and ZFP36L1 are differentially expressed and regulated at the mRNA and protein levels in mouse adipocytes and macrophages.

We evaluated the residue decomposition rates of Bt and non-Bt corn hybrids over a period of 22 mo under field conditions using the litter bag technique. The four corn hybrids used were (i) DKC60-16 (Bt super(+), Cry1Ab protein active against the leptidopteran European corn borer, event MON810), (ii) DKC60-12 (Bt+, Cry3Bb1 protein active against the coleopteran corn rootworm, event MON863), (iii) DKC60-14 (stacked Bt super(++), Cry1Ab and Cry3Bb1 proteins) and, (iv) DKC60-15 (Bt super(-), base genetics). The biochemical and physical properties of the corn residues were determined. No differences in the decomposition rates of the residue from the four corn hybrids were detected. Residue decomposition rate constants were approximately 0.25 d super(-1) for all four hybrids with predicted residue half-lives of about 200 d. No differences in compositional properties, including lignin content, were observed among the four hybrids. Physical compression testing of the chopped residue failed to detect significant differences in mechanical strength properties among the hybrids. This is the first report regarding decomposition of Bt corn residue under field conditions following ambiguous reports from laboratory studies on the relative susceptibility of Bt corn residue to decomposition.

We found that the score distributions of most binding site models did not follow the Gaussian distribution required by many statistical methods. Therefore, we performed an empirical test to establish the optimal threshold for each model. We gauged our computational predictions by comparing with previously known TFBSs in the PCK1 gene promoter of the cytosolic isoform of phosphoenolpyruvate carboxykinase, and achieved a sensitivity of 75% and a specificity of approximately 32%. Almost all known sites overlapped with predicted sites, and several new putative TFBSs were also identified. We validated a predicted SP1 binding site in the control of PCK1 transcription using gel shift and reporter assays. Finally, we applied our computational approach to the prediction of putative TFBSs within the promoter regions of all available RefSeq genes. Our full set of TFBS predictions is freely available at http://bfgl.anri.barc.usda.gov/tfbsConsSites.

Despite recent measurement in United States streams, caffeine's effect on freshwater organisms is not well documented. The present study measured caffeine's lethal and sublethal effects on the freshwater species, Ceriodaphnia dubia, Pimephales promelas, and Chironomus dilutus. These organisms, which are used in standard testing or effluent monitoring, were exposed to aqueous caffeine solutions under static exposure for 48 hours and daily renewed static exposure for 7 days. Averaged responses of 48-hour acute end points indicated that C. dubia was more sensitive to caffeine exposures (LC sub(50) = 60 mg/L) than either P. promelas (LC sub(50) = 100 mg/L) or C. dilutus (LC sub(50) = 1,230 mg/L). Exposure-response slopes confirmed these findings (3% mortality/mg/L for C. dubia; 0.5% mortality/mg/L for P. promelas; and 0.07% mortality/mg/L for C. dilutus). Comparative 7-day responses between C. dubia and P. promelas (LC sub(50) = 46 and 55 mg/L, respectively) were more similar than the broad range of acute values. Sublethal effects measured for caffeine exposure included impaired C. dubia reproduction (IC sub(50) = 44 mg/L) and inhibited P. promelas growth (IC sub(50) = 71 mg/L). According to the results of this study, combined with earlier studies reporting environmental concentrations and product half-lives, caffeine should pose negligible risk for most aquatic vertebrate and invertebrate organisms.

A variety of problems associated with the traditional use of non-selective insecticides for its control include: untoward environmental effects, insecticide resistance, negative impacts on natural enemies, and safety for pesticide applicators and the food supply. Concerns about these consequences have increased the interest in and development of alternative means for CM control that have little or no impact on humans, beneficial organisms and sensitive ecosystems. An effective and selective alternative to chemical insecticides for CM control is the CM granulovirus (CpGV). The virus was first isolated in Mexico and subsequently studied and evaluated in Europe and North America. A variety of research including pathology, pathogenesis and histopathology of the virus, determination of virulence, development of production methods, field use, factors that influence efficacy, commercial development, formulation, and CM resistance to the virus has been conducted. Commercial products of CpGV are now produced in Europe and North America and used by orchardists worldwide. In this paper we present a comprehensive review of the CpGV literature and the role of the virus in integrated pest management.

Peristenus relictus (Ruthe) (formerly P. stygicus Loan) (Hymenoptera: Braconidae: Euphorinae) is the predominant nymphal parasitoid of several Lygus spp. in the warm Mediterranean region and has been a candidate for introduction against Lygus hesperus Knight and L. lineolaris (Palisot de Beauvois) in the southern US. We report a rapid, sensitive, and specific PCR-based assay for diagnosis of P. relictus immature stages within Lygus nymphs that entails three steps: DNA extraction, PCR of the partial mitochondrial COI gene, and agarose gel electrophoresis. The PCR-based methodology is species-specific because the target DNA of other sympatric, congeneric species was not amplified with use of the primers developed for P. relictus diagnosis. The sensitivity of the PCR method, assessed through spike tests, was established by the detection of a ratio of 1:10,000 P. relictus DNA to Lygus DNA. Molecular diagnosis of parasitism of field collected nymphs is achievable in one day, eliminating the need to rear nymphs to obtain adult parasitoids for morphological identification.

Treatment of corn fiber with NaOH and assessment by gas chromatography indicated a prevalence of ferulic acid, with about 90% ester-linked in the cell walls. p-Coumaric acid was much lower at about 10% of the amount of ferulic acid. Histochemical reactions employing acid phloroglucinol and diazotized sulfanilic acid indicated the presence of phenolic acids in cell walls of the pericarp and aleurone layer. Various protocols were tested using milled corn fiber and pretreatment with commercial ferulic acid esterases before cellulase treatment, and dry weight loss and sugars and phenolic acids released into the filtrate were evaluated. Ferulic acid esterases effectively degraded corn fiber and released substantial amounts of ferulic acid and sugars (e.g., glucose and xylose) in the incubation medium. Light microscopy showed that ferulic acid esterase substantially disrupted the aleurone layer but caused little visible damage to the lignified pericarp cell walls. Amounts of compounds released varied with protocols, and one study with various milling methods showed that esterase pretreatment followed by cellulase released about 2.8 to 4.4 and 1.5 to 2.9 times more ferulic acid and glucose, respectively, than cellulase alone. The highest levels for one lot of corn fiber with esterase pretreatment followed by cellulase were 3.9 and 218 mg/g of ferulic acid and glucose, respectively.

This study examined current dead wood amounts in the Coastal Province of Oregon, USA, at multiple spatial scales. Objectives were to: (1) describe current regional amounts of several characteristics of dead wood; (2) compare dead wood amounts across ownerships; (3) determine the relative importance, according to spatial scale, of biophysical and ownership characteristics, to regional dead wood abundance. Dead wood plot data were evaluated with respect to explanatory variables at four spatial scales of resolution: plots, subwatersheds, watersheds and subbasins. The relationships of dead wood characteristics with biophysical attributes and ownership were diverse and scale-specific. Region-wide dead wood abundance and types varied among ownerships, with public lands typically having higher amounts of dead wood and more large dead wood than private lands. Regression analysis of total dead wood volume indicated that ownership was important at the subbasin scale. Growing season moisture stress was important at plot, subwatershed, and watershed scales. Topography was important at the two coarser scales. Multivariate analysis of dead wood gradients showed that ownership was important at all scales, topography at the subbasin scale, historical vegetation at watershed and subbasin scales, and current vegetation at plot and subwatershed scales. Management for dead wood and related biodiversity at watershed to landscape scales should consider the distinct dynamics of snags and logs, the importance of historical effects, and the relevance of ownership patterns.

Intimations From Capitol Reef National Park, Utah AN - 20591689; 8025281 AB - We compared the native bees visiting the flowers of three species of invasive plants, salt-cedar (Tamarix spp.) and white and yellow sweet clover (Melilotus albus, M. officinalis), with those visiting seven concurrently blooming native plant species in mid-summer at three sites in Capitol Reef National Park, Utah. Overall, as many total species of bees visited the flowers of the three invasive plant species as visited the seven natives. On average, invasive species were visited by twice as many bee species as were natives. With a single exception, visitors of invasives were generalist bees, rather than specialists. Colletes petalostemonis, the only native legume specialist recorded, was an abundant forager on the flowers of both species of Melilotus, demonstrating that at least some specialist bees will move to invasive plants that are closely related to their usual hosts. Species abundant on the flowers of invasives tended to collect both pollen and nectar, suggesting that bees are using pollen of Tamarix and Melilotus to provision their offspring. We argue that invasives with entomophilous flowers are unlikely to either facilitate the reproduction of uncommon native plants or consistently compete with them for pollinators. Rather, they are likely, over time, to selectively increase the carrying capacity and population size of native bees, specifically generalists, and specialists of closely related plant species.

We present a conceptual systems model that incorporates the gap between observed and desired levels of the ecological footprint with respect to biocapacity. Addressing this gap (or 'overshoot') can inform strategies to increase or decrease visitation or its associated consumption in the coming years. The feedback mechanism in this conceptual model incorporates a gap between observed and desired ecological footprint levels of tourists and residents. The work is based on longer-term and ongoing study of tourism impacts and ecological footprint assessments from the SPIN-Eco Project. We present historical tourism and environmental data from the province of Siena, Italy and discuss the use of discrete, static environmental indicators as part of an iterative feedback process to manage tourism within biophysical limits. We discuss a necessary shift of emphasis from certain and static numbers to a process-based management model that can reflect slow changes to biophysical resources. As underscored by ecological footprint analysis, the energy and material use associated with tourism and local activity can erode natural capital foundations if that use exceeds the area's biological capacity to support it. The dynamic, and iterative process of using such indicators as management feedback allows us to view sustainability more accurately as a transition and journey, rather than a static destination to which management must arrive.

We surveyed understory vegetation and measured tree canopy cover on permanent plots spanning an experimental fire frequency gradient to test fire frequency and tree canopy effects on plant species richness and community heterogeneity within a mosaic of grassland, oak savanna, oak woodland, and forest communities. Species richness was assessed for all vascular plant species and for three plant functional groups: grasses, forbs, and woody plants. Understory species richness and community heterogeneity were maximized at biennial fire frequencies, consistent with predictions of the intermediate disturbance hypothesis. However, overstory tree species richness was highest in unburned units and declined with increasing fire frequency. Maximum species richness was observed in unburned units for woody species, with biennial fires for forbs, and with near-annual fires for grasses. Savannas and woodlands with intermediate and spatially variable tree canopy cover had greater species richness and community heterogeneity than old-field grasslands or closed-canopy forests. Functional group species richness was positively correlated with functional group cover. Our results suggest that annual to biennial fire frequencies prevent shrubs and trees from competitively excluding grasses and prairie forbs, while spatially variable shading from overstory trees reduces grass dominance and provides a wider range of habitat conditions. Hence, high species richness in savannas is due to both high sample point species richness and high community heterogeneity among sample points, which are maintained by intermediate fire frequencies and variable tree canopy cover.

Reproductive inhibition, although conceptually pleasing, has been difficult to implement because of the lack of a safe, approved avian contraceptive. Recently, however, nicarbazin received regulatory approval in the United States for use as a bait to decrease hatchability of resident Canada goose (Branta canadensis) and feral pigeon (Columba livia) eggs. In anticipation of the feral pigeon registration, we evaluated efficacy by exposing captive pairs of nesting pigeons to nicarbazin bait for 4 h daily. Egg production was unaffected, but only 9 of 22 eggs hatched, a 59% reduction from pre-treatment when each of the 11 test pairs produced 2 nestlings. In the recovery phase, when treated bait was removed, the 11 pairs produced 18 nestlings. All nestlings produced during the study appeared healthy and normal, and there was no mortality among the adult pairs. Nicarbazin is an effective and safe means of reducing hatchability of feral pigeon eggs that can be used within an integrated management plan to reduce feral pigeon populations.

In ocula of these fungi can be effectively produced on-farm in mixtures of compost and vermiculite with a suitable plant host, such as bahiagrass (Paspalum notatum Flugge). Success of this method, however, depends upon utilizing the optimal compost and vermiculite mixture ratio. Experiments were conducted over two years utilizing a complete factorial design with three composts, four mixture ratios, and three AM fungi with the objective of producing regression equations to predict optimal mixture ratios using routine measures of compost nutrient analyses as independent variables. Growth of colonized P. notatum in yard clippings and dairy manure + leaf composts; which were high in N, low in P, with moderate K levels; produced more spores of AM fungi at mixture ratios of 1:2 to 1:4 [v/v compost: vermiculite] relative to higher dilutions. Dilution ratios of 1:19 and 1:49 were best for controlled microbial compost, which was high in P, low in N, and moderately high in K. Simple equations were developed which predict the optimal fraction of compost in the mixture for each of the three AM fungi studied (Glomus intraradices, Glomus mosseae, and Gigaspora rosea). Percent N, P, and K and N:P ratio were the significant independent variables. These equations allow a farmer to choose a mixture ratio for the on-farm propagation of AM fungi knowing only the nutrient analysis of the compost to be used.

The insect presently occurs along the coastal U.S. from Charleston, SC, to Dauphin Island, south of Mobile, AL, and in the interior of Florida. Current control and eradication tactics include manual destruction of infested cactus and the Sterile Insect Technique (SIT), which involves the release of irradiated cactus moths to mate with wild moths and produce sterile offspring. The ability to rear the cactus moths in the laboratory has been crucial in research and development of survey and control techniques. Procedures for rearing the cactus moth in the laboratory on cactus cladodes and artificial diet are described and provide a foundation for the further development of mass-rearing protocols.

Our data suggest that calcium not only acts as an important second messenger in the activation of resistance responses but may also be a downstream mediator of later cell death acceleration and completion of the defense reaction. Accordingly, we propose that the existing model of HR should be amended to include a PM Ca super(2+) ATP pump as an important component of the HR to pathogens in plants.

The ontology allows users to ascribe attributes of plant structure (anatomy and morphology) and developmental stages to data types, such as genes and phenotypes, to provide a semantic framework to make meaningful cross-species and database comparisons. The POC builds upon groundbreaking work by the Gene Ontology Consortium (GOC) by adopting and extending the GOC's principles, existing software and database structure. Over the past year, POC has added hundreds of ontology terms to associate with thousands of genes and gene products from Arabidopsis, rice and maize, which are available through a newly updated web-based browser (http://www.plantontology.org/amigo/go.cgi) for viewing, searching and querying.

Hide swabs were collected in abattoirs from three cohorts of cattle (feedlot origin cattle that had achieved desirable harvest characteristics and dairy- and beef-type cows harvested because of poor productivity). Feces were collected from two cohorts housed in feedlots (cattle that had achieved desirable harvest characteristics and animals identified for salvage recovery because of poor productivity). Facilities were visited on four occasions over a 12-month period. Salmonella enterica isolates were recovered, and organisms were quantified using standard microbiological methodologies. Susceptibility to antimicrobial drugs and serotype were determined for one S. enterica isolate per sample. Salmonella enterica was recovered from 55.6% of 1,681 samples. The prevalences on hides and in feces were 69.6% and 30.3%, respectively. The concentrations of S. enterica organisms averaged (as determined by the most probable number technique) 1.82 log sub(10)/100 cm super(2) of hides and 0.75 log sub(10)/g of feces. None of the isolates recovered from cattle that had achieved desirable harvest characteristics were resistant to four or more drugs. For isolates recovered from animals with poor productivity characteristics, 6.5% were resistant to four or more drugs. Twenty-two serovars were identified, with the most common being Salmonella enterica serovar Anatum (25.5%), Salmonella enterica serovar Montevideo (22.2%), and Salmonella enterica serovar Cerro (12.5%). High-level resistance, i.e., resistance to four or more drugs, was clustered within a few relatively uncommon serovars. These results demonstrate that even though S. enterica isolates are readily recoverable from harvest-ready cattle, multiply resistant variants are rare and are associated with specific serovars in cattle harvested because of poor productivity characteristics.

Strawberry plants (Fmgaria x ananassa Duch. cv. Chandler) were inoculated prior to outplanting with a mixed species inoculum of AM fungi. The inoculum was produced on-the-farm in 2003 in a mixture of compost and vermiculite with bahiagrass (Paspalum notatum Hugge) as host plants. Plants were outplanted into raised black plastic beds on 30 June 2004 and harvested 6-25 June 2005. Inoculation with AM fungi increased yield 17% over uninoculated controls, 5.5 vs. 4.7 kg per ten plant sampling unit, respectively. Inoculation had no significant effect on whole season mean fruit weight, indicating an average increase of 3.6 fruit per plant for inoculated plants over uninoculated plants. Utilization of AM fungus inoculum produced on-farm as an amendment to horticultural potting media for the production of seedlings later outplanted has the potential for significant increases in crop yields.

A total of 1226 coccinellids were sampled by sweepnet, timed searches, Malaise traps, and observation. Four native species--Coleomegilla maculata (De Geer), Hippodamia parenthesis (Say), Hippodamia convergens Guerin-Meneville, and Hippodamia tredecimpunctata tibialis (Say)--collectively comprised 55.8% of all coccinellids sampled, and two non-natives--Coccinella septempunctata L. and Harmonia axyridis (Pallas)--comprised 34.8% of coccinellids sampled. H. parenthesis, H. convergens, C. septempunctata, and H. axyridis were also seen commonly while sampling for bean leaf beetle and soybean aphid. The survey had . 95% probability of detecting species that comprised a minimum proportion of 0.0025, 0.0032, and 0.011 of all coccinellids, respectively, across habitats, among only agricultural habitats, and among only non-agricultural habitats. A. bipunctata (L.), Coccinella transversoguttata richardsoni Brown, and Coccinella novemnotata Herbst were not detected in the survey. The results provide further evidence that these three previously common native species have become difficult to detect within the northern Great Plains, and suggest that conservation programs for them are urgently needed. H. axyridis and C. septempunctata were often found in non-agricultural habitats, providing further evidence of their pervasiveness in the landscape. Adult C. septempunctata were feeding upon a native aphid, Uroleucon atriceps (Gillette and Palmer) (Hemiptera: Aphididae), on goldenrod at a prairie in Richland County, North Dakota. This result provides further documentation of non-target predation by non-native coccinellids, and suggests that further studies are needed to determine fully the impact of non-native coccinellids on the native aphid fauna.

The memoir starts with an early career-directing experience with nutrition and cholera and proceeds with a long thread of interest in folic acid malabsorption as one of the determinants of nutritional anemia in Asia and the tropics. The thread continues with the relationship of folate and associated vitamins to brain function and aging as a prototype of the study of the interface of aging biology and nutritional biology. My current interest in world hunger and famine and their impact on human security may circle back to studies of the great Bengal famine and the first Bangladesh survey of malnutrition.

Assumptions include that with minimum or no-tillage farming methods, there will be no deleterious production or environmental effects. A long-term field study was established in eastern Nebraska, USA, to compare the switchgrass managed as a biomass energy crop versus no-till corn on a non-irrigated site, marginal for row-crop production, in the western Corn Belt. Our objective in this paper is to report on corn stover removal effects on corn grain yields and potential ethanol production in both cropping systems. Corn, under no-till management, and switchgrass were grown at three N fertilizer levels. In the first 5 years (2001-2005), removal of half the available stover significantly reduced corn yields. During that same time period, the potential ethanol yield for switchgrass was equal to or greater than the potential total ethanol yield of corn grain and harvested stover fertilized at the same optimum N rate. The effect of crop residue removal on crop productivity needs to be investigated in other agro-ecosystems and the potential use of dedicated perennial biomass energy crops should remain a viable renewable energy option on non-irrigated marginal croplands.

However, a distinct population of F. verticillioides is pathogenic on banana and does not produce fumonisins. Fumonisin-producing strains from maize cause leaf lesions, developmental abnormalities, stunting, and sometimes death of maize seedlings, whereas fumonisin-nonproducing banana strains do not. A Southern analysis of banana strains did not detect genes in the fumonisin biosynthetic gene (FUM) cluster but did detect genes flanking the cluster. Nucleotide sequence analysis of the genomic region carrying the flanking genes revealed that the FUM cluster was absent in banana strains except for portions of FUM21 and FUM19, which are the terminal genes at each end of the cluster. Polymerase chain reaction analysis confirmed the absence of the cluster in all banana strains examined. Cotransformation of a banana strain with two overlapping cosmids, which together contain the entire FUM cluster, yielded fumonisin-producing transformants that were pathogenic on maize seedlings. Conversely, maize strains that possess the FUM cluster but do not produce fumonisins because of mutations in FUM1, a polyketide synthase gene, were not pathogenic on maize seedlings. Together, the data indicate that fumonisin production may have been lost by deletion of the FUM cluster in the banana population of F. verticillioides but that fumonisin production could be restored by molecular genetic complementation. The results also indicate that fumonisin production by F. verticillioides is required for development of foliar disease symptoms on maize seedlings.

The biological activities that these fungi might be playing in coffee seeds remain unknown, but in other plants some of the genera isolated have been reported to protect against plant pathogens.

Syd. Approximately 10 km south of Canal Point, FL, another cultivar (CP 72-2086), also considered resistant to P. melanocephala, was found to be infected with a rust Samples were sent to the USDA-APHIS National Mycologist and the USDA-ARS Systematic Mycology and Microbiology Laboratory in Beltsville, MD for identification. Observed morphological features were consistent with P. kuehnii E.J. Butler. Uredinial lesions were orange and variable in size, measuring 650 to 850 X 26 to 32 mu m, hypophyllous, ellipsoidal to fusiform in shape, and distinctly lighter than pustules of P. melanocephala that were present in the area along with P. kuehnii. Urediniospores were mostly obovoid to pyriform or broadly ellipsoidal, variable in size, 32 to 45 X 25 to 30 mu m, and moderately ecbinulate with mosdy evenly distributed spines 2 to 4.5 mu m apart. Walls were orange-to-light cinnamon brown, 1 to 2.5 mu m thick with a pronounced apical wall thickening as much as 7 mu m, and 4 to 5 equatorial pores. Similar orange uredinial lesions were subsequently observed on the same two cultivars and several other cultivars, including CPCL99-1777 and CPCL01-1055, at different locations in South Florida. Telia and teliospores were not observed. The nuclear large subunit rDNA region of the rust infecting cv. CP 80-1743 (BPI 878243, GenBank Accession No. EU164549) and the ITS1, 5.8S, and ITS2 rDNA regions of the rust infecting CP 80-1743 (GenBank Accession No. EU176009) and CP 72-2086 (GenBank Accession No. EU176008) were sequenced. All sequences were identical to sequences of P. kuehnii and distinct from known sequences of P. melanocephala. To our knowledge, this is the first confirmed record of P. kuehnii infecting sugarcane in the Western Hemisphere, and the disease appears to be distributed widely in the South Florida sugarcane-growing area. Although listed by P. Holliday as occurring in Cuba, the Dominican Republic, and Mexico, CMI map no. 215 ed. 4 does not include these three countries in the known distribution of P. kuehnii. P. kuehnii has also been reported in the literature as present in Hawaii. However, examination of the specimen label found that the specimen cited in those papers (BPI 079624) was actually collected in Tahiti. Therefore, the report from Hawaii is erroneous.

Furthermore, it is possible that alternative hosts could provide a means of overwintering of the pathogen, providing inoculum to initiate epidemics in future years. To clarify the potential importance of soybean rust on nonsoybean legumes and their role in overwintering of the disease, multiple accessions of clover, cowpea, pea, kudzu, lima bean, snap bean, and single accessions of coffee senna, Florida beggarweed, hemp sesbania, hyacinth bean, partridge pea, and showy crotalaria were inoculated under greenhouse conditions with urediniospores of P. pachyrhizi; infected soybean plants served as a control. The four criteria used to assess susceptibility were lesion density, proportion of lesions with sporulating uredinia, average number of uredinia per lesion, and average uredinia diameter, each determined 2 weeks following inoculation. Based on lesion densities, percentage of lesions with sporalation, and average numbers of uredinia per lesion, soybean, kudzu, and pea were the most susceptible species, followed by snap bean. However, because infected pea plants defoliated rapidly, urediniospore production presumably was limited, lessening the potential for epidemics on pea. Cultivars of snap bean produced numerous brown to reddish-brown lesions, many of which sporulated, but numbers of uredinia per lesion were lower than on soybean, kudzu, or pea. The presence of both tan (susceptible) and reddish-brown (resistant) lesions on kudzu demonstrated physiological differentiation on that host. Some kudzu plants appeared to be potentially excellent hosts for overwintering of the disease. The average number of uredinia per lesion appeared to be a valid measurement with which to compare host susceptibilities, and may have epidemiological significance. High susceptibility of a host was characterized by numerous uredinia with a wide range of sizes within individual lesions. In contrast, low susceptibility to rust was characterized by no or a few small uredinia.

Soybean rust severities of individual accessions ranged from 0% (resistant) to 30.0% (susceptible). In MG III and IV, the most resistant accessions were PI 506863, PI 567341, and PI 567351B, with severities less than 1.2%. In MG V, the most resistant accessions were PI 181456, PI 398288, PI 404134B, and PI 507305, with severities less than 0.3%. In MG VI, the most resistant accessions were PI 587886, PI 587880A, and PI 587880B, with severities less than 0.3%. In MG VII and VIII, the most resistant were PI 587905 and PI 605779E, with severities less than 1.0%. In MG IX, the most resistant accessions were PI 594754, PI 605833, PI 576102B, and PI 567104B, with severities less than 1.0%. The resistance in 10 selected accessions from MG VI, VII, VIII, and XI was confirmed in subsequent greenhouse and field experiments where severities of 0.4% or less and reddish-brown lesions with sporulation levels less than 3.0 were observed. These accessions, with low severities in the adult plant field evaluation, may be new sources of resistance to P. pachyrhizi.

To test this, detached crab apple blossoms were maintained for various periods and at different temperatures before applying inoculum to hypanthia. Inoculum potential on hypanthia due to wetting was evaluated by subjecting detached stigma-inoculated blossoms ( similar to 10 super(6) CFU per flower) to varying amounts and durations of simulated rain (or dew) at 14 degree C. Blossoms of varying age on mature 'Gala' apple trees were inoculated on hypanthia with 10 super(2), 10 super(4), or 10 super(6) CFU per flower. In the laboratory, susceptibility decreased with flower age at rates that increased with temperature. Wetness periods up to 12 h resulted in populations on hypanthia of <10 super(3) CFU per flower; 24 h of wetness resulted in similar to 10 super(4) or similar to 10 super(5) CFU. A dose response was shown in the orchard, and regression curves indicated steepest decline of susceptibility during initial days after petal expansion. Disease models incorporating a blossom-age component may be effective because they indicate the potential for infection when temperatures favor rapid bacterial growth on stigmas within a window of high hypanthial susceptibility. Further investigation of these relationships could lead to advancements in determining fire blight risk.

Although the biological effects of Indiana's road network are not well-understood, the combination of intense habitat fragmentation within the state and substantial road density may have detrimental effects on many wildlife species. From 13 April 2005 to 23 February 2006, we conducted a series of statewide road mortality surveys to develop a vertebrate road mortality species index and to identify factors influencing the frequency of road mortality within the state. We established nine survey routes and sampled each route eight times over one year (two surveys per route per season). There were 563 mortality events (0.4 kills/km surveyed) representing more than 50 species recorded across the nine routes during 72 surveys. For mammals, birds, and reptiles/amphibians, respectively, the most common species encountered were Virginia opossum (Didelphis virginkma, N =X 179), American robin (Turdus migratoriiis, N = 9), and painted turtle (Chrysemys picta, N = 12). Across routes for all species combined, mortality varied from 0.2-1.0 events per km surveyed. Road mortality was less frequent in winter than in other seasons. Our study suggests that road mortality impacts a wide variety of species from different taxonomic groups and that the frequency of road mortality varies across sites, probably due to a variety of habitat considerations, road characteristics, and attributes of local vertebrate communities.

These bacterial populations cooperate to promote their own survival and the chronic nature of the infection. Few studies have performed extensive surveys of the bacterial populations that occur within different types of chronic wound biofilms. The use of 3 separate16S-based molecular amplifications followed by pyrosequencing, shotgun Sanger sequencing, and denaturing gradient gel electrophoresis were utilized to survey the major populations of bacteria that occur in the pathogenic biofilms of three types of chronic wound types: diabetic foot ulcers (D), venous leg ulcers (V), and pressure ulcers (P). Results There are specific major populations of bacteria that were evident in the biofilms of all chronic wound types, including Staphylococcus, Pseudomonas, Peptoniphilus, Enterobacter, Stenotrophomonas, Finegoldia, and Serratia spp. Each of the wound types reveals marked differences in bacterial populations, such as pressure ulcers in which 62% of the populations were identified as obligate anaerobes. There were also populations of bacteria that were identified but not recognized as wound pathogens, such as Abiotrophia para-adiacens and Rhodopseudomonas spp. Results of molecular analyses were also compared to those obtained using traditional culture-based diagnostics. Only in one wound type did culture methods correctly identify the primary bacterial population indicating the need for improved diagnostic methods. Conclusion If clinicians can gain a better understanding of the wound's microbiota, it will give them a greater understanding of the wound's ecology and will allow them to better manage healing of the wound improving the prognosis of patients. This research highlights the necessity to begin evaluating, studying, and treating chronic wound pathogenic biofilms as multi-species entities in order to improve the outcomes of patients. This survey will also foster the pioneering and development of new molecular diagnostic tools, which can be used to identify the community compositions of chronic wound pathogenic biofilms and other medical biofilm infections.

In 2003, the California Department of Public Health (CDPH) began to quantify the impacts of skunk-variant rabies and to assess the feasibility of using oral rabies vaccination (ORV) as a containment measure. The CDPH rabies case data for skunks were spatially depicted and analyzed using a geographic information system. Statewide, rabid skunks (1992-2003) primarily occurred in seven physiographic regions: Central Coast, North Coast, North Sierra, Sacramento Valley, San Francisco Bay and Delta, San Joaquin Valley, and South Sierra. Detailed analysis of rabid skunks in San Luis Obispo (SLO) and Santa Barbara (SB) counties showed that skunk rabies was endemic in the coastal plain of SLO County between 1992 and 2000, but only became epizootic in SB County during 2002. Despite the widespread distribution of striped skunks (Mephitis mephitis) throughout most of California, the skunk rabies variant has not been found in Los Angeles County since 1979. Results imply that future ORV campaigns for skunk-variant rabies in the Pacific Coastal Plain could deter spread from SLO into SB County, as well as deterring the reintroduction of skunk-variant rabies into southern California.

On histologic examination, the brainstem had areas of vacuolation in neuropil and extensive multifocal mineralization of blood vessels with occasional occlusion of the lumen. Some of the clinical and pathologic features of this case were similar to the CWD of white-tailed deer. However, the tissues were negative for PrP super(d) by IHC. Because the lesions were more prominent in the obex region of the brainstem, it is speculated that this would have resulted in clinical signs similar to CWD in white-tailed deer. To our knowledge, neither cerebrovascular mineralization nor clinicopathologic changes resembling CWD have previously been described in white-tailed deer without the presence of PrP super(d). Such a case should be considered in a differential diagnosis of CWD of white-tailed deer.

Complete tissue digestion of tongues revealed that 19% of the raccoons, 26% of the coyotes, and none of the seven skunks tested were infected with Trichinella spp. Cats were subsequently experimentally infected by feeding them the raccoon tissues containing muscle larvae, and muscle larvae isolated from the collected tongues were experimentally transmitted to mice. Multiplex polymerase chain reaction analysis of the isolated muscle larvae demonstrated two distinct bands migrating at 127 base pairs (bp) and 316 bp in all samples, which together are diagnostic for Trichinella murrelli; the isolates were assigned Istituto Superiore di Sanita (ISS) codes ISS1656 through ISS1667, and ISS1708 through ISS1710 by the International Trichinella Reference Centre. These findings extend the geographic range of T. murrelli into Wisconsin, USA.

This study evaluates the role of Salmonella spp. in wild bird mortality events in the United States from 1985 through 2004. Analyses were performed to calculate the frequency of these events and the proportional mortality by species, year, month, state, and region. Salmonellosis was a significant contributor to mortality in many species of birds; particularly in passerines, for which 21.5% of all mortality events involved salmonellosis. The proportional mortality averaged a 12% annual increase over the 20-yr period, with seasonal peaks in January and April. Increased salmonellosis-related mortality in New England, Southeastern, and Mountain-Prairie states was identified. Based on the results of this study, salmonellosis can be considered an important zoonotic disease of wild birds.

Knowledge from molecular genetic studies could help to devise strategies in alleviating this problem; however, few peanut DNA sequences are available in the public database. In order to understand the molecular basis of host resistance to aflatoxin contamination, a large-scale project was conducted to generate expressed sequence tags (ESTs) from developing seeds to identify resistance-related genes involved in defense response against Aspergillus infection and subsequent aflatoxin contamination. Results We constructed six different cDNA libraries derived from developing peanut seeds at three reproduction stages (R5, R6 and R7) from a resistant and a susceptible cultivated peanut genotypes, 'Tifrunner' (susceptible to Aspergillus infection with higher aflatoxin contamination and resistant to TSWV) and 'GT-C20' (resistant to Aspergillus with reduced aflatoxin contamination and susceptible to TSWV). The developing peanut seed tissues were challenged by A. parasiticus and drought stress in the field. A total of 24,192 randomly selected cDNA clones from six libraries were sequenced. After removing vector sequences and quality trimming, 21,777 high-quality EST sequences were generated. Sequence clustering and assembling resulted in 8,689 unique EST sequences with 1,741 tentative consensus EST sequences (TCs) and 6,948 singleton ESTs. Functional classification was performed according to MIPS functional catalogue criteria. The unique EST sequences were divided into twenty-two categories. A similarity search against the non-redundant protein database available from NCBI indicated that 84.78% of total ESTs showed significant similarity to known proteins, of which 165 genes had been previously reported in peanuts. There were differences in overall expression patterns in different libraries and genotypes. A number of sequences were expressed throughout all of the libraries, representing constitutive expressed sequences. In order to identify resistance-related genes with significantly differential expression, a statistical analysis to estimate the relative abundance (R) was used to compare the relative abundance of each gene transcripts in each cDNA library. Thirty six and forty seven unique EST sequences with threshold of R > 4 from libraries of 'GT-C20' and 'Tifrunner', respectively, were selected for examination of temporal gene expression patterns according to EST frequencies. Nine and eight resistance-related genes with significant up-regulation were obtained in 'GT-C20' and 'Tifrunner' libraries, respectively. Among them, three genes were common in both genotypes. Furthermore, a comparison of our EST sequences with other plant sequences in the TIGR Gene Indices libraries showed that the percentage of peanut EST matched to Arabidopsis thaliana, maize (Zea mays), Medicago truncatula, rapeseed (Brassica napus), rice (Oryza sativa), soybean (Glycine max) and wheat (Triticum aestivum) ESTs ranged from 33.84% to 79.46% with the sequence identity . 80%. These results revealed that peanut ESTs are more closely related to legume species than to cereal crops, and more homologous to dicot than to monocot plant species. Conclusion The developed ESTs can be used to discover novel sequences or genes, to identify resistance-related genes and to detect the differences among alleles or markers between these resistant and susceptible peanut genotypes. Additionally, this large collection of cultivated peanut EST sequences will make it possible to construct microarrays for gene expression studies and for further characterization of host resistance mechanisms. It will be a valuable genomic resource for the peanut community. The 21,777 ESTs have been deposited to the NCBI GenBank database with accession numbers ES702769 to ES724546 .

A xylitol negative mutant with a transposon insertion in the xylitol 4-dehydrogenase gene (xdh) was isolated and genomic DNA around the transposon was sequenced. Consequently, six consecutive genes, xytB-G are located downstream of xdh in the same strand. These seven genes are cotranscribed as a single transcript in a P. ananatis xylitol-utilizing mutant, suggesting that they comprise an operon. In addition to xdh, xytF also encodes oxidoreductase that is a member of the short-chain dehydrogenase/reductase family. Recombinant Escherichia coli that heterologously expresses the Xdh protein converts xylitol to xylulose as expected. On the other hand, the recombinant XytF protein has activity with L-arabitol but not with xylitol. XytB, xytD and xytE have significant sequence similarities to genes encoding the substrate-binding, ATP-binding and permease subunits, respectively, of ATP-binding cassette transporters. Although the physiological role of the operon remains unknown, the operon appears to be involved in uptake and metabolism of a various sugar alcohols. A gene encoding a DeoR-type transcriptional regulator, xytR, is located upstream of the operon in the opposite strand and a single nucleotide substitution that could cause a nonsense mutation is present in the xytR gene of the xylitol-utilizing mutant. This result suggests that the product of xytR negatively controls expression of the operon like other DeoR regulators.

We investigated the geographic distribution of Map in the Lower Florida Keys from February 2005 through May 2006 via collection of blood and fecal pellets from 51 live-captured deer, collection of 550 fecal samples from the ground, and by necropsies of 90 carcasses. Tissue and fecal samples also were submitted from 30 raccoons (Procyon lotor), three feral cats (Felis catus), an opossum (Didelphis virginiana), and a Lower Keys marsh rabbit (Sylvilagus palustris hefneri). Mycobacterium avium subsp. paratuberculosis was identified in 23 Key deer fecal samples collected from the ground, tissue samples from two clinically ill Key deer, and from the mesenteric lymph node of a raccoon. The results of this study indicate that Map persists in the Key deer population and environment at a low prevalence, but its distribution currently is limited to a relatively small geographic area within the range of Key deer.

Our results demonstrate that common multipurpose printing paper is a satisfactory substrate and superior to the more absorbent 3 MM chromatography paper for the transport of plasmid DNA through the mail. We show that depositing as little as 100 ng of purified plasmid onto multipurpose printing paper is sufficient to allow recovery of the mailed DNA. Also observed was an inverse correlation between vector size and recovery of intact plasmid DNA, thus larger binary vectors require the deposition of more plasmid to ensure successful recovery.

Traditional methods for reducing overabundant wildlife, such as hunting and trapping, are often restricted or infeasible in urban and suburban areas. Additional management options are needed. For the past 15 years, scientists with the US Department of Agriculture's (USDA) Wildlife Services' National Wildlife Research Center have been developing and testing contraceptive agents. This research has resulted in the development of several reproductive inhibitors and has forced regulatory bodies to determine where the regulatory authority for wildlife contraceptives will reside. The regulatory authority for contraceptives for wildlife and feral animals has recently been moved from the US Food and Drug Administration (FDA) to the US Environmental Protection Agency (EPA). The first contraceptive registered by the EPA since this move was OvoControl-G for reducing the hatchability of Canada goose eggs. OvoControl was registered in 2005 by Innolytics, LLC working in cooperation with the National Wildlife Research Center. A similar product, OvoControl-P, was registered in 2007 as a contraceptive technique for pigeons. Another product developed by the National Wildlife Research Center, GonaCon immunocontraceptive vaccine, is in the registration process for managing white-tailed deer populations. This manuscript will describe the products that have been and are currently undergoing registration as contraceptives in the United States of America, and the data required for those products.

However, little is known of the ecological impacts of large fires on both historical and contemporary landscapes. The present paper presents a review of the current knowledge of the effects of large fires in the United States by important ecosystems written by regional experts. The ecosystems are (1) ponderosa pine-Douglas-fir, (2) sagebrush-grasslands, (3) pioe+/-on-juniper, (4) chaparral, (5) mixed-conifer, and (6) spruce-fir. This review found that large fires were common on most historical western US landscapes and they will continue to be common today with exceptions. Sagebrush ecosystems are currently experiencing larger, more severe, and more frequent large fires compared to historical conditions due to exotic cheatgrass invasions. Historical large fires in south-west ponderosa pine forest created a mixed severity mosaic dominated by non-lethal surface fires while today's large fires are mostly high severity crown fires. While large fires play an important role in landscape ecology for most regions, their importance is much less in the dry pioe+/-on-juniper forests and sagebrush-grasslands. Fire management must address the role of large fires in maintaining the health of many US fire-dominated ecosystems.

The potential of antagonistic microorganisms to be developed into biological control agents has been investigated in several crop systems, as alternatives to chemical fungicides for control of mycotoxigenic fungi. Laboratory and greenhouse studies have identified a number of bacterial, yeast, and filamentous fungal isolates that reduce crop contamination of mycotoxigenic fungi, although investigations of field efficacy have been limited. These studies demonstrate that the diversity of ecological interactions between mycotoxigenic fungi and other resident microorganisms may provide tools for development of biocontrol methods to reduce mycotoxin contamination.

To survive in these diverse conditions it must sense and respond to various environmental cues. One micronutrient required for most forms of life is iron. Bioavailable iron has been shown to be an important global regulator for many bacteria where it not only regulates a wide variety of genes involved in general cell physiology but also virulence determinants. In this study we used microarrays to study differential gene regulation in DC3000 in response to changes in levels of cell-associated iron. Results DC3000 cultures were grown under highly controlled conditions and analyzed after the addition of iron citrate or sodium citrate to the media. In the cultures supplemented with iron, we found that cell-associated iron increased rapidly while culture densities were not significantly different over 4 hours when compared to cultures with sodium citrate added. Microarray analysis of samples taken from before and after the addition of either sodium citrate or iron citrate identified 386 differentially regulated genes with high statistical confidence. Differentially regulated genes were clustered based on expression patterns observed between comparison of samples taken at different time points and with different supplements. This analysis grouped genes associated with the same regulatory motifs and/or had similar putative or known function. Conclusion This study shows iron is rapidly taken up from the medium by iron-depleted DC3000 cultures and that bioavailable iron is a global cue for the expression of iron transport, storage, and known virulence factors in DC3000.

Early efforts were focused on identifying the risk factors for increased aflatoxin contamination and helped to document the importance of drought, high soil temperatures, and pod damage. Later efforts were focused on the development of screening techniques and the identification of sources of resistance to Aspergillus colonization and/or aflatoxin contamination. This laid the foundation for a conventional resistance breeding program and has resulted in the development of peanut breeding lines that have high yield and low aflatoxin contamination relative to standard control cultivars. Recent research efforts include studies on the use of molecular genetic approaches to reduce aflatoxin contamination. This includes the evaluation of genetically engineered peanut and the development of molecular markers.

However NT must be economically viable if it is to be adopted. Costs of production and economic returns were evaluated for an irrigated, continuous corn (Zea mays L.) system under CT and NT over 6 yr on a clay loam soil in northern Colorado. Yield responses to N fertilization were included to determine economic optimum fertilization rates under each tillage system. Corn grain yields at economic optimum N fertilizer rates were 1.1 to 1.4 Mg ha super(-1) lower for NT than for CT. However, net returns were $46 to 74 ha super(- 1) higher for NT than for CT due to reductions in operating costs of $57 to 114 ha super(-1) and reductions in machinery ownership costs of $87 to 90 ha super(- 1). Operating cost savings were realized largely due to fuel and labor reductions of 75% and 71 to 72%, respectively, and in spite of higher N fertilizer requirements of 16 to 55 kg ha super(-1) for NT compared to CT. No- till, irrigated, continuous corn appears to be an economically viable option for replacing CT production systems in the central Great Plains, especially when combined with the environmental benefits of the NT system.

This group of compounds is characterized by a substituted 2-pyrrolidone ring attached to a 12-carbon polyunsaturated backbone. Several of the fusarins contain an epoxide substitution on the pyrrolidone ring and are highly mutagenic. This paper describes the development of seven monoclonal antibodies and immunoassays for detecting fusarins C and A. Fusarin C was isolated and conjugated to ovalbumin to produce the immunogen. Competitive indirect enzyme-linked immunosorbent assays (CI-ELISAs) were developed based upon the isolated monoclonal antibodies. The concentrations of fusarin C able to inhibit colour development by 50% (IC50) in CI-ELISAs were 1.0, 2.0, 3.6, 23.4, 28.9, 31.4, and 66.7 ng ml-1 for clones 1-38, 1-30, 1-5, 1-7, 1-43, 1-25, and 1-21, respectively. Cross-reactivity with fusarin A was 44.8, 51.4, 41.1, 174.0, 62.6, 78.2, and 98.0% for clones 1-38, 1-30, 1-5, 1-7, 1-43, 1-25, and 1-21, respectively. Given the sensitivity of these antibodies for fusarins it is expected that, with further development, they may be useful for detecting fusarins at relevant levels in foods.

The observation that 'Appar' is heterostylic, a key taxonomic character distinguishing Lewis flax from other members of the Linum perenne complex, created a need for further study in order to resolve the taxonomic position of both Lewis flax and the 'Appar' cultivar. We grew 10 plants each of nine European, nine North American, and three putative 'Appar' seed sources, measured 18 morphologic variables on each plant, and examined genetic variation using randomly amplified polymorphic DNA (RAPD). We also performed self- and cross- pollinations within and among source groups. North American collections differed from European collections for 12 of the 18 morphologic variables. 'Appar' collections were morphologically similar to European collections and differed from North American collections for 13 of the 18 variables. RAPD data also showed that 'Appar' sources clustered with European, and both were distinct from North American sources. European and 'Appar' collections were self-sterile and interfertile, whereas North American collections were self- fertile but reproductively isolated from European and 'Appar' collections. We conclude that L. lewisii is a distinct species within the L. perenne complex and that 'Appar' should be classified as L. perenne. This study provides an example of how questions regarding origin and/or taxonomy of plant materials developed for restoration can be resolved.

In response to concerns about associated wildfire hazards, land managers in the western United States are carrying out extensive fuel-reduction thinning programs. Although reductions in cover by woody vegetation seem likely to cause changes in herbaceous communities, few published studies have reported on consequences of such treatments for native or exotic plant species. We compared vegetation and abiotic characteristics between paired thinned and unthinned chaparral and oak woodland communities of southwestern Oregon 4-7 yr posttreatment and contrasted impacts of manual vs. mechanical treatments. Herbaceous cover increased on thinned sites, but species richness did not change. Herbaceous communities at thinned sites had an early postdisturbance type of composition dominated by native annual forbs and exotic annual grasses; cover by annuals was nearly twice as high on treated as on untreated sites. Absolute and proportional cover of native annual forbs increased more than any other trait group, whereas exotic annual forbs and native perennial forbs declined. Exotic annual grass cover (absolute and proportional) increased, whereas cover by native perennial grasses did not. Shrub reestablishment was sparse after thinning, probably because of a lack of fire-stimulated germination. Manual and mechanical treatment impacts on abiotic site conditions differed, but differences in vegetation impacts were not statistically significant. Fuel-reduction thinning may have some unintended negative impacts, including expansion of exotic grasses, reductions in native perennial species cover, persistent domination by annuals, and increased surface fuels. Coupled with sparse tree or shrub regeneration, these alterations suggest that ecological-state changes may occur in treated communities. Such changes might be mitigated by retaining more woody cover than is currently retained, seeding with native perennials after treatment, or other practices; further research is needed to inform management in these ecosystems.

Also, it is intended that the added ammonia nitrogen in ammonia treated corn (1 g per kg corn) may satisfy the yeast nutritional requirement for free amino nitrogen (FAN). In this study, procedures for ammoniation, liquefaction, saccharification, and fermentation at two scales (12-L and 50-mL) were used to determine the fermentation rate, final ethanol concentration, and ethanol yield from starch in ammoniated or nonammoniated corn. The maximum achievable ethanol concentration at 50 h fermentation time was lower with ammoniated corn than with nonammoniated corn. The extra nitrogen in ammoniated corn satisfied some of the yeast requirements for FAN, thereby reducing the requirement for corn steep liquor. Based upon these results, ammoniation of corn does not appear to have a positive impact on the fermentability of corn to ethanol. Ammoniation may still be cost effective, if the advantages in terms of improved separations outweigh the disadvantages in terms of decreased fermentability.

We examined contaminant profiles in super(137)Cs/ super(7)Be-dated sediment cores taken near wastewater treatment plants in the Chesapeake Bay watershed (CB), Maryland and Jamaica Bay (JB), New York. In JB, biocide occurrences tracked the time course of biocide usage and wastewater treatment strategies employed, first appearing in the 1950s (triclocarban) and 1960s (triclosan), and peaking in the late 1960s and 1970s (24 +/- 0.54 and 0.8 +/- 0.4 mg/kg dry weight, respectively). In CB, where the time of sediment accumulation was not as well constrained by super(137)Cs depth profiles, triclocarban was only measurable in super(137)Cs-bearing sediments, peaking at 3.6 +/- 0.6 mg/kg midway through the core and exceeding 1 mg/kg in recent deposits. In contrast, triclosan concentrations were low or not detectable in the CB core. Analysis of CB sediment by tandem mass spectrometry produced the first evidence for complete sequential dechlorination of triclocarban to the transformation products dichloro-, monochloro-, and unsubstituted carbanilide, which were detected at maxima of 15.5 +/- 1.8, 4.1 +/- 2.4, and 0.5 +/- 0.1 mg/kg, respectively. Concentrations of all carbanilide congeners combined were correlated with heavy metals (R super(2) > 0.64, P < 0.01), thereby identifying wastewater as the principal pathway of contamination. Environmental persistence over the past 40 years was observed for triclosan and triclocarban in JB, and for triclocarban's diphenylurea backbone in CB sediments.

Merr.] in many soybean growing countries of the world. Host plant resistance is a very useful component of an integrated pest management program to control an insect problem. A maturity group (MG) IV plant introduction (PI) 243540 showed strong antibiosis resistance against the Ohio biotype of the soybean aphid. The objective of this study was to determine the inheritance of soybean aphid resistance gene(s) in PI 243540. The F sub(1), F sub(2), and F sub(2)-derived F sub(3) families from a cross between an aphid susceptible cultivar Wyandot and resistant PI 243540 were screened in a greenhouse with the Ohio biotype of the soybean aphid. All F sub(1) plants were resistant to the soybean aphid and super(2) analysis of segregation of 341 F sub(2) plants indicated a fit to a single dominant gene ratio of 3:1 (P = 0.51). Segregation in 330 F sub(2:3) families fit an expected 1:2:1 ratio (P = 0.40). Our results indicate that a single dominant gene controls the soybean aphid resistance in PI 243540. The simple inheritance of this gene should be helpful to quickly transfer the gene to susceptible elite cultivars using the backcross breeding approach.

Factors associated with CFL resistance in H sub(2)O sub(2)-induced mutants included (i) mutations in gyrA gene, predominantly (63%) Asp super(87) arrow right Asn and less (37%) Ser super(83) arrow right Phe substitutions, (ii) mutations in the regulatory genes of MarRAB or SoxRS or in the individual structural genes of these operons. Such mutations are induced by H sub(2)O sub(2) in a much lower extent. Reduced OmpF expression simultaneously with enhanced efflux was detected only in one mutant strain and 20% of mutant strains had increased CFL efflux from the cells.

A field study was conducted from 2000 to 2002 to study the effects of four N treatments (0, 100, 200, and 300 kg N ha super(-1) per crop) on a wheat (Triticum aestivum L.) and maize (Zea mays L.) double cropping system under 70 plus or minus 15% field capacity in the North China Plain (NCP). The root zone water quality model (RZWQM), with the crop estimation through resource and environment synthesis (CERES) plant growth modules incorporated, was evaluated for its simulation of crop production, soil water, and N leaching in the double cropping system. Soil water content, biomass, and grain yield were better simulated with normalized root mean square errors (NRMSE, RMSE divided by mean observed value) from 0.11 to 0.15 than soil NO sub(3)-N and plant N uptake that had NRMSE from 0.19 to 0.43 across these treatments. The long-term simulation with historical weather data showed that, at 200 kg N ha super(-1) per crop application rate, auto-irrigation triggered at 50% of the field capacity and recharged to 60% field capacity in the 0- to 50-cm soil profile were adequate for obtaining acceptable yield levels in this intensified double cropping system. Results also showed potential savings of more than 30% of the current N application rates per crop from 300 to 200 kg N ha super(-1), which could reduce about 60% of the N leaching without compromising crop yields.

We measured the distribution and total stock of SOC to a depth of 20 cm under conventional tillage (CvT), conservation tillage (CsT), and pasture in 87 production fields from the Southern Piedmont and Coastal Plain Major Land Resource Areas. Across locations, SOC at a depth of 0 to 20 cm was: pasture (38.9 Mg ha super(-1)) > CsT (27.9 Mg ha super(-1)) > CvT (22.2 Mg ha super(-1)) (P < 0.02). Variation in SOC was explained by management (41.6%), surface horizon clay content (5.2%), and mean annual temperature (1.0%). Higher clay content and cooler temperature contributed to higher SOC. Management affected SOC primarily at the soil surface (0-5 cm). All SOC fractions (i.e., total SOC, particulate organic C, soil microbial biomass C, and potential C mineralization) were strongly correlated across a diversity of soils and management systems (r = 0.85-0.96). The stratification ratio (concentration at the soil surface/concentration at a lower depth) of SOC fractions differed among management systems (P < 0.0001), and was 4.2 to 6.1 under pastures, 2.6 to 4.7 under CsT, and 1.4 to 2.4 under CvT; these results agree with a threshold value of 2 to distinguish historically degraded soils with improved soil conditions from degraded soils. This on- farm survey of SOC complements experimental data and shows that pastures and conservation tillage will lead to significant SOC sequestration throughout the region, resulting in improved soil quality and potential to mitigate CO sub(2) emissions.

Here we have utilized a bacterial tag-encoded FLX 16s rDNA amplicon pyrosequencing (bTEFAP) approach that is able to perform diversity analyses of gastrointestinal populations. bTEFAP is relatively inexpensive in terms of both time and labor due to the implementation of a novel tag priming method and an efficient bioinformatics pipeline. We have evaluated the microbiome from the feces of 20 commercial, lactating dairy cows. Results Ubiquitous bacteria detected from the cattle feces included Clostridium, Bacteroides, Porpyhyromonas, Ruminococcus, Alistipes, Lachnospiraceae, Prevotella, Lachnospira, Enterococcus, Oscillospira, Cytophage, Anaerotruncus, and Acidaminococcus spp. Foodborne pathogenic bacteria were detected in several of the cattle, a total of 4 cows were found to be positive for Salmonella spp (tentative enterica) and 6 cows were positive for Campylobacter spp. (tentative lanienae). Conclusion Using bTEFAP we have examined the microbiota in the feces of cattle. As these methods continue to mature we will better understand the ecology of the major populations of bacteria the lower intestinal tract. This in turn will allow for a better understanding of ways in which the intestinal microbiome contributes to animal health, productivity and wellbeing.

Recent outbreaks of Fusarium keratitis were associated with contact lens wear and with ReNu with MoistureLoc contact lens care solution, and biofilm formation on contact lens/lens cases was proposed to play a role in this outbreak. However, no in vitro model for contact lens-associated fungal biofilm has been developed. In this study, we developed and characterized in vitro models of biofilm formation on various soft contact lenses using three species of Fusarium and Candida albicans. The contact lenses tested were etafilcon A, galyfilcon A, lotrafilcon A, balafilcon A, alphafilcon A, and polymacon. Our results showed that clinical isolates of Fusarium and C. albicans formed biofilms on all types of lenses tested and that the biofilm architecture varied with the lens type. Moreover, differences in hyphal content and architecture were found between the biofilms formed by these fungi. We also found that two recently isolated keratitis-associated fusaria formed robust biofilms, while the reference ATCC 36031 strain (recommended by the International Organization for Standardization guidelines for testing of disinfectants) failed to form biofilm. Furthermore, using the developed in vitro biofilm model, we showed that phylogenetically diverse planktonic fusaria and Candida were susceptible to MoistureLoc and MultiPlus. However, Fusarium biofilms exhibited reduced susceptibility against these solutions in a species- and time-dependent manner. This in vitro model should provide a better understanding of the biology and pathogenesis of lens-related fungal keratitis.

Our objectives were to use a soil geomorphology-erodibility approach to locate sediment sources in the Walnut Gulch Experimental Watershed (WGEW). Major soil mapping units were sampled along transects in six subwatersheds (SWs). At each sampling point, latitude-longitude, slope gradient, slope aspect, and hillslope position were recorded. Samples collected from the surface 5.0 cm were characterized for a range of basic soil characterization properties. Additionally, super(137)Cs, super(40)K, super(226)Ra, and stable C isotope distributions were quantified as potential source area indicators. Suspended sediment samples collected from WGEW and SW flumes were characterized for the same properties. Relative to the SW soils, the suspended sediments were generally enriched in silt, clay, organic C, inorganic C, total N, extractable cations, extractable Fe and Mn, super(13)C from C3 plants, super(40)K, and super(226)Ra. The suspended sediment from three SWs was enriched in super(137)Cs. Eleven characterization parameters were used in a multivariate mixing model to identify the SWs contributing the greatest sediment loads in the WGEW. The mixing model results indicated that three SWs were contributing approximately 86% of the sediment, and that the greatest amount originated in the three SWs with the lowest soil aggregation index (highest erodibility).These results were supported by the {delta} super(13)C data, which indicated that approximately 65% of the stable C isotopes leaving the WGEW during this period were derived from C3 plants (shrubs), the dominant vegetation on the three SWs.

Since under-watering can decrease yields, the question becomes one of finding the optimum application regime. An irrigation experiment was set up to apply water at six different application rates, ranging from 33% to 144% of normal, with hopes of identifying the regime that produces maximum yield. Two cultivars, Acala Maxxa and Acala PhytoGen-72 (Gossypium hirsutum L.), were planted on sandy soil and irrigated daily with a highly efficient subsurface drip irrigation system for four seasons. The results showed that on the average there was no significant difference in the yield of the two cultivars and there was no significant difference in the yield for the three wettest treatments. The driest of the three wettest treatments, treatment 4, was a critical point on the water production function curve. It represented the least amount of water applied that still produced essentially maximum yield, and it had the highest water use efficiency. This critical level of water application during mid-season was found to be, on the average, 95% of Class A pan evaporation; it corresponded to a total seasonal application of 654mm of water. Any application less than this critical level decreased yields. Reducing the water application by 5% below the critical level caused about a 4.6% reduction in yield. The critical level produced a soil moisture level that remained nearly constant throughout the season. The final plant height was closely related to the depth of water applied, with the wettest treatment producing plant heights of 2.0m, and the driest treatment producing plant heights of 0.6m. At the extremes of the water application rates there were some small differences in the early-season growth rate of the plants, but the main cause of differences in final plant height was the date of cutout (cessation of main stem node production). The length of season for the driest treatment was about 4 weeks shorter than for the wettest treatment on both cultivars. Results showed that deficit irrigation of cotton on sandy soil can greatly reduce yield, and the practice should probably be avoided.

With the goal of producing alfalfa populations with altered nitrate N uptake, our objectives were to develop, assess, and refine an inexpensive selection method using Br super(-) as an analog for nitrate under field conditions. Two selection schemes using divergent herbage Br super(-) concentration and/or divergent herbage Br super(-) uptake, both in combination with high herbage N content, produced two Cycle 1 and four Cycle 2 alfalfa populations. We evaluated these populations for both Br super(-) uptake and nitrate N uptake (estimated by N derived from fertilizer, Ndff [ super(15)N- labeled]) for one regrowth period in two locations in each of 2 yr. Weak associations between Br super(-) uptake and Ndff were found during the establishment year, but strong correlations were found between Br super(-) concentration and fraction of Ndff (fNdff) (r = 0.83) and between Br super(-) uptake and Ndff (r = 0.85 to 0.90) when populations were evaluated during the first production year. Populations selected for high Br super(-) concentration or uptake had greater Br super(-) concentration and uptake, fNdff, and Ndff than populations selected for low Br super(-). Our method of selecting alfalfa plants for differences in herbage Br super(-) concentration or uptake in combination with high herbage N content is the first to successfully produce alfalfa populations that differ in nitrate N uptake in a field environment.

The objective of this study was to develop a robust sampling technique for measuring SVOCs in humid environments. Test atmospheres were generated at ambient temperatures (23 +/-1.5 degree C) and 25, 50, and 80% relative humidity (RH). Sorbent material used included Tenax, graphitized carbon, and carbon molecular sieve (CMS). Sorbent tubes were challenged with 2, 4, 8, 12, and 24 L of air at various RHs. Sorbent tubes with CMS material performed poorly at both 50 and 80% RH due to excessive sorption of water. Heating of CMS tubes during sampling or dry-purging of CMS tubes post sampling effectively reduced water sorption with heating of tubes being preferred due to the higher recovery and reproducibility. Tenax tubes had breakthrough of the more volatile compounds and tended to form artifacts with increasing volumes of air sampled. Graphitized carbon sorbent tubes containing Carbopack X and Carbopack C performed best with quantitative recovery of all compounds at all RHs and sampling volumes tested. The graphitized carbon tubes were taken to the field for further testing. Field samples taken from inside swine feeding operations showed that butanoic acid, 4-methylphenol, 4-ethylphenol, indole, and 3-methylindole were the compounds detected most often above their odor threshold values. Field samples taken from a poultry facility demonstrated that butanoic acid, 3-methylbutanoic acid, and 4-methylphenol were the compounds above their odor threshold values detected most often. relative humidity, CAFO, VOC, SVOC, thermal desorption, swine, poultry, air quality, odor JF - Environmental Science & Technology AU - Li, Hong AU - Xin, Hongwei AU - Trabue, Steven L AU - Burns, Robert AU - Scoggin, Kenwood D AD - National Soil Tilth Laboratory, USDA Agricultural Research Service, 2110 University Boulevard, Ames Iowa 50011 Y1 - 2008 PY - 2008 DA - 2008 SP - 3745 EP - 3750 PB - American Chemical Society, 1155 16th St., NW Washington DC 20036 USA VL - 42 IS - 10 SN - 0013-936X, 0013-936X KW - Pollution Abstracts; Chemoreception Abstracts KW - Relative humidity KW - Odor thresholds KW - Poultry KW - poultry KW - feeding KW - Air quality KW - Odors KW - artifacts KW - Sorbents KW - Carbon KW - Air sampling KW - Sampling KW - Temperature effects KW - Feeding KW - Sorption KW - Desorption KW - Temperature KW - Humidity KW - Indole KW - Volatiles KW - indoles KW - Organic compounds KW - Odorants KW - Butyric acid KW - Sampling methods KW - Volatile organic compounds KW - R 18050:Chemoreception correlates of behavior KW - P 0000:AIR POLLUTION UR - http://libproxy.lib.unc.edu/login?url=http://search.proquest.com/docview/20016367?accountid=14244 L2 - http://vb3lk7eb4t.search.serialssolutions.com/?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQ%3Apollution&rft_val_fmt=info:ofi/fmt:kev:mtx:journal&rft.genre=article&rft.jtitle=Environmental+Science+%26+Technology&rft.atitle=Field+Sampling+Method+for+Quantifying+Odorants+in+Humid+Environments&rft.au=Li%2C+Hong%3BXin%2C+Hongwei%3BTrabue%2C+Steven+L%3BBurns%2C+Robert%3BScoggin%2C+Kenwood+D&rft.aulast=Li&rft.aufirst=Hong&rft.date=2008-01-01&rft.volume=42&rft.issue=10&rft.spage=3745&rft.isbn=&rft.btitle=&rft.title=Environmental+Science+%26+Technology&rft.issn=0013936X&rft_id=info:doi/10.1021%2Fes7031407 LA - English DB - ProQuest Environmental Science Collection N1 - Date revised - 2008-06-01 N1 - Last updated - 2011-12-14 N1 - SubjectsTermNotLitGenreText - Odors; Air quality; Sorbents; Humidity; Volatile organic compounds; Desorption; Sorption; poultry; indoles; Air sampling; feeding; artifacts; Sampling methods; Temperature; Sampling; Carbon; Butyric acid; Relative humidity; Poultry; Odor thresholds; Feeding; Odorants; Volatiles; Organic compounds; Temperature effects; Indole DO - http://dx.doi.org/10.1021/es7031407 ER - TY - JOUR T1 - Chemical Structures of Manure from Conventional and Phytase Transgenic Pigs Investigated by Advanced Solid-State NMR Spectroscopy AN - 20012270; 8133962 AB - Nonpoint phosphorus (P) pollution from animal manure is becoming a serious global problem. The current solution for the swine industry includes the enzyme phytase as a component in oil meal and cereal grain-based swine diets. A long-term approach is the production of transgenic phytase pigs that express phytase in the salivary glands and secrete it in the saliva. This study provides a detailed comparison of chemical structures of manure from conventional pigs and transgenic pigs that express phytase under growing and finishing phases using new solid-state NMR techniques. Spectral editing techniques and quantitative NMR techniques were used to identify and quantify specific functional groups. Two-dimensional super(1)H- super(13)C heteronuclear correlation NMR was used to detect their connectivity. Manure from conventional and transgenic pigs had similar peptide, carbohydrate, and fatty acid components, while those from transgenic pigs contained more carbohydrates and fewer nonpolar alkyls. There was no consistent effect from diets with or without supplemental phosphate or growth stages. KW: NMR; transgenic; characterization; pig manure; spectral editing.

For example, diversity and abundance of insects may also be related to structural complexity, nutrition, or productivity of plants. In arid systems, primary production is generally enhanced by supplemental moisture, which may provide food resources of greater abundance and quality for herbivores, resulting in greater insect diversity and abundance. Although the association of insect distributions with sites of either high plant diversity or productivity has been studied extensively, the relative importance of these two factors in influencing insect diversity and abundance remains unclear. We examined how insect communities in sagebrush steppe responded to two plant community treatments (a crested wheatgrass monoculture and a diverse community of native shrubs, grasses, and forbs) and three irrigation regimes (summer irrigation, fall/spring irrigation, and ambient precipitation only) on an experimental site designed to test protective cap designs for isolating buried hazardous waste. In both 2000 and 2001, insect diversity and abundance were positively correlated with both plant diversity and irrigation early in the summer; however, by the end of the summer, insect distributions were more strongly influenced by irrigation treatment. Our results suggest that during the dry season in this semi-arid shrub-steppe system, plant diversity may be secondary to moisture effects in influencing insect distributions.

These strains are similar in surface charge, shape, and size, and differ primarily in their surface hydrophobicity and tendency to form aggregates. The amount of bacteria that were retained in the sand increased with decreasing water saturation, especially for the more hydrophobic strain that formed larger cell aggregates. Most of the cells were retained close to the column inlet, and the rate of deposition rapidly decreased with depth. The experimental data were analyzed using a mathematical model that accounted for deposition on two kinetic sites. Consideration of depth-dependent deposition in the model formulation significantly improved the description of the data, and the amount of cell retention was typically dominated by this site. The depth- dependent deposition coefficient tended to increase with decreasing water content, especially for the hydrophobic bacteria. Straining is believed to account for these observations because it increases in magnitude with increasing cell and aggregate size and when a greater fraction of the water flows through a larger number of small pore spaces with decreasing water content. Cell retention on the other kinetic deposition site was well described using a conventional model for attachment and detachment. Consistent with interaction energy calculations for bacteria attachment, however, low amounts of cell retention occurred on this site. Attempts to separately determine the amounts of attachment to solid-water and air-water interfaces were confounded by the influence of straining.

Effective and economic field management methods including commonly used surface sealing technique and soil amendments are needed for achieving emission reductions. This research determined the effectiveness of ammonium thiosulfate (ATS) and composted manure amendments to surface soil in combination with water application or high density polyethylene (HDPE) tarp on reducing emissions of 1,3-D from soil columns. Surface treatments included an untreated control, water seal (single water application at time of fumigant injection), ATS amendments at 1:1 and 2:1 molar ratio of ATS:fumigant, composted steer manure at 3.5 kg m super(-2), and HDPE tarp over 1:1 ATS or the manure amendment. Cumulative 1,3-D emission loss over two weeks was greatest for the control (52% of applied). The HDPE tarp over ATS and manure treatments had the lowest 1,3-D emissions at 24 and 16%, respectively. Treatments with ATS or manure alone reduced 1,3-D emissions (29-39%) more effectively than water seal (43%) and further benefit was gained with the addition of HDPE tarp. Amendment of surface soil with organic materials shows greater potential in minimizing fumigant emissions than with chemicals with the need for a better understanding of the organic- fumigant reaction mechanism.

The imagery had three bands (green, red, and near-infrared). Three subsets from both the QuickBird and SPOT 5 images were extracted and used as study sites. The same subsets were extracted from both images. The images were subjected to supervised image analysis. Accuracy assessments performed on QuickBird classification maps from the three sites had producer's and user's accuracies for giant reed that ranged from 92% to 100%. Accuracy assessments performed on SPOT 5 classification maps from the three sites had producer's and user's accuracies for giant reed ranging from 75.7% to 93.3%. The lower accuracies of the SPOT 5 image classifications were attributed to its coarser resolution.

In agricultural and forestry systems, this progression is well studied with regard to the influence of va ious environmental factors on plant development (Reddy et al. 1992, Olszyk et al. 1998, Zhang et al. 2001, Romero et al. 2004). In contrast, the morphological development of p ants in natural areas is rarely subjected to detailed study, so the maturation patterns of their vegetative and reproductive structures are often unknown. Detailed knowledge of developmental patterns of invasive plants that cause ecological damage can enhance management efforts. Characterization of vegetative bud and shoot development, for example, can assist the accurate timing of control tactics so they coincide with vulnerable developmental stages of the target plant.

We physically separated coarse (0.2-2.0 mu m e.s.d.), medium (0.02-0.2 mu m e.s.d.), and fine (> 0.02 mu m e.s.d.) clay subfractions from three Midwestern soils and characterized the organic material associated with these subfractions using super(13)C-CPMAS-NMR, DTG, SEM-EDX, incubations, and radiocarbon age. Most of the C in the coarse clay subfraction was present as discrete particles (0.2-5 mu m as seen in SEM images) of black carbon (BC) and consisted of approximately 60% aromatic C, with the remainder being a mixture of aliphatic, anomeric and carboxylic C. We hypothesize that BC particles were originally charcoal formed during prairie fires. As the BC particles aged in soil their surfaces were oxidized to form carboxylic groups and anomeric and aliphatic C accumulated in the BC particles either by adsorption of dissolved biogenic compounds from the soil solution or by direct deposition of biogenic materials from microbes living within the BC particles. The biogenic soil organic matter was physically separated with the medium and fine clay subfractions and was dominated by aliphatic, anomeric, and carboxylic C. The results indicate that the biogenic humic materials in our soils have little aromatic C, which is inconsistent with the traditional heteropolymer model of humic substances.

The majority of seeds (96%) in the soil profile were distributed within 7.6 cm of the surface at both sites. Mowing plumeless thistle when most of the flower heads were at the full bud or postbloom stage did not reduce seed bank or plant densities, unlike mowing at full bloom, which significantly and quickly reduced both. Musk thistle responded differently, with plant density declining only with the postbloom mowing treatment, which occurred after the parent plant had dispersed seeds and died. Seed bank densities were unchanged by this treatment. This indicates that other factors may limit the recruitment and maintenance of musk thistle, such as allelochemical production by parents and interspecific plant competition. Density of musk thistle declined over an 11-yr period at one monitoring site, whereas plumeless thistle remained unchanged. The disproportionate seed-destroying activities of the weed biological control agent Rhinocyllus conicus on musk thistle may explain this difference. Nomenclature: musk thistle, Carduus nutans Wienm.

This parasitic wasp has steadily dispersed since its establishment in 1984, and it is now present in 11 states, a 38% increase since our last report in 2003, and has been found in 69 counties in the United States. Peristenus digoneutis is now present in all of the northeastern states, is moving westward along the southern edge of Lake Erie, and is well established in at least three Canadian provinces.

This study demonstrates that vesicles composed of DEPC and DMPG at 98 and 2 mol %, respectively, formed a supported bilayer with unruptured vesicles present when adsorbed onto the self-assembled monolayer. Also, the partially formed supported bilayer apparently deadsorbed in the presence of 1-butyl-3-methylimidazolium chloride, suggesting that surface-bilayer interactions are weaker on a hydrophilic modified gold surface composed of 50/50 11MU/11MUA than the surface-bilayer interactions on silica.

The objective of this work was to determine whether we could alter grain methionine concentration in random-mated maize populations by mass selection for methionine concentration using a microbial assay. In one study, we developed two populations by selecting for high or low methionine concentration (HM or LM, respectively) for three generations starting from the random-mated population BS11. Grain from these populations was used to formulate diets for a feeding trial in which 15 rats were fed HM grain and 15 rats were fed LM grain. Rats on the HM diet had a 0.018 higher feed efficiency (g gain/g feed) than rats on the LM diet. In a second study, we performed three cycles of selection for high or low methionine concentration starting with two random-mated populations, BS11 and BS31. We evaluated each cycle of selection in a field trial with two replications in each of two years. Methionine concentration was significantly correlated with the cycle of selection, changing on average 0.004 g methionine/100 g grain per cycle. Kernel mass, %N, oil, protein, starch, tryptophan, and lysine concentration did not exhibit significant correlations with cycle of selection. We conclude that recurrent selection for grain methionine concentration using a microbial assay is an effective method to alter methionine content.

Aside from the reported persistence of elevated available P and K levels in clay-rich soils one year after mound abandonment, the relative stability of nutrient concentrations from one season to the next is largely unknown. Nutrient concentrations were concurrently analysed from ant mounds and undisturbed soils as well as plant samples collected from warm-season turfgrass in a commercial sod production agroecosystem. Initial collection of soil and turfgrass samples coincided with peak annual biomass (September 2006); the second soil sample collection occurred over twelve weeks later during turfgrass dormancy and ant brood minimum (December 2006). Total C, C/N ratios, organic matter (OM), and Zn super(2+) concentrations as well as pH of ant mound soils were significantly higher than control plot soils; these trends persisted across seasons. Turfgrass harvested from ant mound perimeters in September exhibited elevated N, P, Ca super(2+), S, Cu super(2+), Fe super(2+), and Na super(+) concentrations. Evaluation of the relative stability of soil parameters across seasons revealed a significant drop in ant nest pH from September to December 2006. Total N of mound soils was distinctively greater than control soil counterparts during September only. Soil P, K super(+), Ca super(2+), Mg super(2+) and S (all macronutrients), as well as Na super(+) concentrations from ant mound soils were substantially elevated during the late Autumn to Winter transition compared to control soil locations, whereas Fe super(2+) and Mn super(2+) levels (both micronutrients) were significantly lower in ant mound soils versus control soil environments. Continuous pedo-turbation by imported fire ants as well as seasonal shifts in mound soil chemistry resulting from changes in assimilation/dissimilation among mound biota may influence the site-specific effectiveness of microfaunal pathogens (e.g., Thelohania solenopsae) or parasites (e.g., Orasema spp.) identified as classical biological control agents of non-native Solenopsis spp. Therefore, further study of the intrinsic complexities of soil ecosystem dynamics of imported fire ant mounds across several seasons is warranted.

This finding has important implications for young children, who tend to ingest more dust than adults and may be more susceptible to some of the putative developmental effects of PBDEs. Absorption parameters of PBDEs from ingested dust are unknown; therefore, the objectives of this study were to determine and to compare the uptake of PBDEs from either household dust (NIST Standard Reference Material 2585) or a corn oil solution. Male rats were administered dust or corn oil doses at 1 or 6 mu g of PBDEs kg super(-1) body wt in the diet for 21 days (n = 4 rats per group). The concentrations of 15 PBDEs were measured in adipose tissue and liver from each treatment group and showed that bioconcentration was congener dependent, but for the majority of congeners, the concentrations did not differ with either dose level or dose vehicle. Hepatic Cyp2b1 and 2b2 mRNA expression increased in rats receiving the higher PBDE doses, suggesting potential effects on metabolic activity. Retention of PBDEs in tissues ranged from <5% of the dose for BDE-209 to 70% for BDEs-47, 100, and 153 but generally did not differ between the high dust and high oil treatment groups. Excretion via the feces was significantly lower in the high oil dosed rats suggesting differences in absorption, excretion, and/or metabolism. The present study shows that PBDEs in dust are readily bioavailable and are biologically active, as indicated by increased transcription of hepatic enzymes.

It is a potent carcinogen, and its presence markedly reduces the value of grain. Host-plant resistance to A. flavus infection and subsequent aflatoxin accumulation is generally considered a desirable means of reducing losses to aflatoxin. Maize germplasm lines with resistance to aflatoxin contamination have been developed in Mississippi. Four of the aflatoxin-resistant lines and six other lines were used as parents to produce a diallel cross. The diallel cross was evaluated for resistance to aflatoxin contamination in field trials conducted in Mississippi in 2005 and 2006. General combining ability (GCA) and specific combining ability (SCA) were highly significant sources of variation each year. Reciprocal effects were not significant in 2005 or in the combined analysis over years. In the analysis over years, GCA effects for reduced aflatoxin were highly significant for the four lines developed as sources of resistance: Mp313E, Mp494, Mp715, and Mp717. The GCA effect for reduced aflatoxin was also highly significant for Mo18W and NC408. These lines should be useful in developing maize lines and hybrids with resistance to aflatoxin contamination. Breeding methods that maximize the use of GCA should be effective in enhancing resistance to aflatoxin accumulation when using these germplasm lines.

Holub.] has historically been of minor importance to livestock agriculture in cooler regions of the temperate zone. As its use in these regions expands, it becomes increasingly important to understand the effect of infection by its fungal endophyte (Neotyphodium coenophialum Morgan-Jones and Gams) on agronomic fitness of tall fescue. Our objective was to determine the effect of endophyte infection status on forage yield and survival of tall fescue under field conditions in which freezing temperatures, combined with lack of persistent snow cover, constitute the most significant stress factor. In Experiment 1, we evaluated 427 half-sib families of four tall fescue cultivars, half endophyte-infected (E+) and half endophyte-free (E-), for forage yield and survival. There was no effect of endophyte removal on either forage yield or survival, despite complete stand loss of one cultivar during two winters. In Experiment 2, we evaluated 640 clones of confirmed endophyte status, half E+ and half E-, for survival under two management regimes at four Wisconsin locations. Results were nearly identical to those for Experiment 1, with complete mortality in the unadapted cultivar and high survival rates in the three adapted cultivars, regardless of endophyte status, management, or location. In conclusion, we found no evidence that endophyte removal resulted in any disadvantage to tall fescue host-plant survival under harsh winter conditions. In regions where freezing temperatures and desiccating winds provide the only or most important abiotic stress factor, removal of endophytic fungi do not appear to reduce fitness of their tall fescue host.

Holub.] is an important source of forage but often contains a fungal endophyte [Neotyphodium coenophialum (Morgan-Jones and Gams) Glenn, Bacon, and Hanlin] that can produce alkaloids and decrease animal performance. Removing the endophyte can reduce agronomic performance and persistence. An improved cultivar ('Jesup') with a novel (nontoxic) endophyte (trademark "MaxQ") has improved agronomic performance. Persistence may be related to agronomic traits and animal feeding preferences. We tested for variation in animal preference among two harvests by testing each of three hays made from Jesup tall fescue that varied in endophyte status (no endophyte, containing the novel endophyte, or containing a wild-type endophyte that produces alkaloids associated with toxicosis). We tested for preference using goats (Capra hircus), sheep (Ovis aries), and cattle (Bos taurus). All possible pairs were tested using traditional analysis of variance as well as multidimensional scaling. Multidimensional scaling of the animal preferences indicated that two dimensions were being used to rank the hays. The first dimension for all three animal species was related to variation in forage nutritive value. The second dimension was not correlated with any of the measured variables. Endophyte status was not a factor in the preferences expressed by the three animal species. It appears that no effective feedback mechanism exists related to endophyte status.

While Moraxella spp. are the primary etiologic agent of pinkeye, surveys of flora from the conjunctivae of livestock from around the world have indicated that a variety of bacterial commensals occupy this niche. We used molecular biology-based methods to determine the composition of bacterial flora in the conjunctivae of normal dairy and beef cattle from Maryland (n = 113), and beef cattle with clinical BKC from Louisiana (n = 42). Three regimens were used: 16S rRNA PCR and DGGE analysis of amplicons; 16S rRNA PCR and cloning of amplicons into Escherichia coli followed by screening and sequencing of clones harboring inserts; and culture of bacteria on chromogenic agar followed by 16S rRNA PCR and sequencing. Most taxa were comprised of saprophytes found in the environment, such as Bacillus, Pantoea, E. coli, and Exiguobacterium. Moraxella spp. were infrequently observed. Some species, such as Propionibacterium acnes, represent taxa not previously associated with the conjunctivae. Bacillus pumilus and Bacillus licheniformis isolates from the conjunctivae of Maryland cattle were genetically distinct from isolates previously implicated in septic infections in cattle at the same location. We conclude that employing 16S rRNA-based methods for bacterial identification can be useful in defining the flora present in the conjunctivae of normal cattle, and those with BKC.

Whereas a plethora of genes involved in cell wall metabolism, ethylene biosynthesis, fruit softening, and secondary metabolism during fruit development and ripening have been identified in other plant species, little is known of the genes involved in these processes in watermelon. A microarray and quantitative Real-Time PCR-based study was conducted in watermelon [Citrullus lanatus (Thunb.) Matsum. & Nakai var. lanatus] in order to elucidate the flow of events associated with fruit development and ripening in this species. RNA from three different maturation stages of watermelon fruits, as well as leaf, were collected from field grown plants during three consecutive years, and analyzed for gene expression using high-density photolithography microarrays and quantitative PCR. Results High-density photolithography arrays, composed of probes of 832 EST-unigenes from a subtracted, fruit development, cDNA library of watermelon were utilized to examine gene expression at three distinct time-points in watermelon fruit development. Analysis was performed with field-grown fruits over three consecutive growing seasons. Microarray analysis identified three hundred and thirty-five unique ESTs that are differentially regulated by at least two-fold in watermelon fruits during the early, ripening, or mature stage when compared to leaf. Of the 335 ESTs identified, 211 share significant homology with known gene products and 96 had no significant matches with any database accession. Of the modulated watermelon ESTs related to annotated genes, a significant number were found to be associated with or involved in the vascular system, carotenoid biosynthesis, transcriptional regulation, pathogen and stress response, and ethylene biosynthesis. Ethylene bioassays, performed with a closely related watermelon genotype with a similar phenotype, i.e. seeded, bright red flesh, dark green rind, etc., determined that ethylene levels were highest during the green fruit stage followed by a decrease during the white and pink fruit stages. Additionally, quantitative Real-Time PCR was used to validate modulation of 127 ESTs that were differentially expressed in developing and ripening fruits based on array analysis. Conclusion This study identified numerous ESTs with putative involvement in the watermelon fruit developmental and ripening process, in particular the involvement of the vascular system and ethylene. The production of ethylene during fruit development in watermelon gives further support to the role of ethylene in fruit development in non-climacteric fruits.

Natural infection was enhanced by interplanting alternate host Ribes spp. among test seedlings. Parents of the families were from three geographic provinces, representing the northern Rocky Mountains of Idaho (WWP), the Cascade Range of Oregon and Washington (WWP), and the Siskiyou Mountains of California and Oregon (SP). Several families of each pine species had major gene resistance (MGR), or genes for partial resistance (PR), or both types. Under the chronic epidemic conditions that prevailed, susceptible controls of both species became infected and died within a few years. Families with MGR segregated in expected Mendelian ratios (susceptibility/resistance), but each R gene-Cr1 in sugar pine and Cr2 in western white pine-was eventually defeated by biotypes of the rust with specific virulence to it (vcr1 and vcr2, respectively). WWP families from Idaho, which lacked Cr2, performed the best overall, ranging from 44 to 64% rust-free; a few WWP families from the Cascades, both with and without Cr2, performed comparably. Families with PR were not specifically vulnerable to vcr1 or vcr2. PR was less frequent in SP than WWP, and SP families had steeper infection rate curves than WWP. Combining PR in pedigrees with MGR may prolong protection of MGR by inhibiting selection and epidemic increase of vcr genes in the rust.

Although the effect of these stresses on the expression of sucrose synthase, a key enzyme in the carbon metabolism of many storage organs, has been investigated in several starch-accumulating plant organs, little information on their effect on sucrose synthase expression in sucrose-storing organs is available. To determine the effect of wounding, anoxia and cold on a sucrose-storing organ, sugarbeet (Beta vulgaris) roots were wounded, subjected to anoxic conditions, or exposed to cold temperatures, and transcript and protein levels for the organ's two sucrose synthase genes (SBSS1 and SBSS2) and sucrose synthase enzyme activity were determined during 24h and 7d time course experiments. Wounding, anoxia and cold were associated with several-fold changes in sucrose synthase transcript levels. SBSS1 transcript levels were elevated in wounded, anoxic and cold-treated roots; SBSS2 transcript levels were elevated in response to wounding, cold, and short exposures (3-12h) to anoxic conditions and reduced in roots exposed to anoxic conditions for more than 24h. SBSS1 and SBSS2 protein levels, however, exhibited little change in stressed roots, even after 7d. Enzyme activity was also relatively unchanged in stressed roots, except for small activity differences of 1-2d duration that were unrelated to transcriptional changes. The disparity between transcript levels, protein abundance and enzyme activity indicate that SBSS1 and SBSS2 expression in response to wounding, anoxia and cold may be regulated by post-transcriptional mechanisms. The unresponsiveness of sucrose synthase protein levels or enzyme activity to wounding, anoxia and cold questions the importance of this enzyme to stress responses in sugarbeet root.

The real-time technique was validated against 39 CTV strains from around the world as well as with the aphid vector, Aphis gossypii, given a 48h acquisition access period on a CTV source plant. The assay was effective for quantitation of the viral template in infected plants and in single aphids. CTV detection was compared from different plant tissues and for different RNA isolation methods from aphids. Less than 1fg was consistently detected when RNA transcripts were diluted in extracts from healthy plants while RNA copies carried by single aphids were estimated to be between 12,000 and 13,000,000. The assay was more sensitive and less time consuming than ELISA or traditional RT-PCR. The real-time RT-PCR assay developed is a valuable new tool for detection and titer quantitation of CTV.

Samples collected during four months of the summer production period from two locations (northern and southern parts of central Slovakia) contained 10 super(5)-10 super(7) (cfu) yeasts and about 10 super(2) (cfu) of mold per gram of wet weight. Further characterization by conventional taxonomy and sequence comparison of D1/D2 region from 26S rRNA gene revealed Mucor circinelloides v. Tieghem as the predominant filamentous fungus. A novel Geotrichum sp. together with Kluyveromyces (K. lactis/K. marxianus) was identified as the most abundant yeast species. Occasionally other yeasts, such as Candida inconspicua, Candida silvae, Pichia fermentans and Trichosporon domesticum were found. Conventional taxonomy readily identified isolates to the genus level, but DNA sequence comparison was capable of discriminating them at the species level.

Outside of Africa MCF is mainly caused by ovine herpesvirus 2 (OvHV-2) which is carried subclinically by sheep. Cell-free virus is present in nasal secretions of shedding sheep and aerosol is the primary mode of transmission. Although OvHV-2 has never been propagated in vitro, experimental infection involving intranasal nebulization with nasal secretions from shedding sheep has been used to induce MCF in cattle and bison. This method of inoculation has never been tested in rabbits, which are the primary small animal model. The objectives of this study were to determine whether rabbits become infected with OvHV-2 after intranasal nebulization with cell-free virus from sheep nasal secretions and whether they develop MCF with consistent gross and histologic lesions. Five of eight rabbits became infected, showed clinical signs and developed histologic lesions typical of MCF including multisystemic vasculitis and perivascular lymphoid accumulation. These lesions are similar to those reported in rabbits infected by intravenous injection with tissues from clinically affected animals containing cell-associated virus. Viral DNA and mRNA transcripts of a structural viral protein were present in tissues from affected rabbits suggesting that viral replication occurred, although the significance in terms of pathogenesis is unknown. This work demonstrates that OvHV-2 infection of rabbits by intranasal nebulization is a potentially useful model that mimics the natural route of infection and may be used to study viral replication and pathogenesis.

Severe infection can dramatically reduce grain yield and quality. Resistant cultivars have been identified from several countries. However, only a few sources of FHB resistance showed stable FHB resistance across environments and have been used as the major source of resistance in breeding programs. To diversify the wheat FHB-resistance gene pool, new sources of FHB-resistance are desired. Ninety-four selected wheat landraces and cultivars, mainly from China and Japan, have been evaluated for FHB severity and deoxynivalenol (DON) content. Low DON content was correlated with resistance to the FHB symptom spread within an infected spike, but not with the resistance to FHB initial infection. Two-thirds of the accessions were either resistant or moderately resistant to FHB. Among them, 26 highly resistant accessions mainly originated from China and Japan. Fifteen of them had less than 2 mg kg super(-1) DON in harvested grain, six of which showed all three types of resistance. Most of these resistant accessions lack known pedigree relations to Sumai 3, suggesting that some of them may carry genes for resistance to FHB and DON accumulation different from those in Sumai 3.

The cell preparation methods that were considered included filtration and centrifugation (at various speeds and for different durations). For a given ionic strength condition, it was found that cells prepared by filtration were more negatively charged and hydrophobic than cells prepared by centrifugation. Increasing the centrifugation speed (force imposed) or duration produced cells with a higher zeta potential (less negative) and a lower hydrophobicity. Column transport experiments for E. coli D21 g were also conducted with ultra pure quartz sand and the same solution chemistries. The first-order retention rate coefficient for E. coli D21 g increased with increasing speed and duration of centrifugation, and was lowest in the case of filtered cells. Moreover, the influence of cell preparation method was more pronounced in lower ionic strength solutions.

Simple and robust molecular markers that enable early detection of Lr34/Yr18 are a major advancement in wheat (Triticum aestivum L.) breeding. An insertion/deletion size variant located at the csLV34 locus on chromosome 7D within an intron sequence of a sulfate transporter-like gene tightly linked to the Lr34/Yr18 dual rust resistance gene was used to examine a global collection of wheat cultivars, landraces, and D genome- containing diploid and polyploid species of wheat relatives. Two predominant allelic size variants, csLV34a and b, found among the wheat cultivars showed disparate variation in different wheat growing zones. A strong association was observed between the presence of Lr34/Yr18 and the csLV34b allele and wheat lines known to have Lr34/Yr18 that had the csLV34a allele were rare. All landraces with the exception of those from China were predominantly of the csLV34a type. Only one size variant, csLV34a, was detected among the diploid and polyploid D genome-containing species, indicating that csLV34b arose subsequent to hexaploid bread wheat synthesis. The lineage of the csLV34b allele associated with Lr34/Yr18 in modern wheat cultivars from North and South America, CIMMYT, Australia, and Russia was tracked back to the cultivars Mentana and Ardito developed in Italy by Nazareno Strampelli in the early 1900s. The robustness of the csLV34 marker in postulating the likely occurrence of Lr34/Yr18 across a wide range of wheat germplasm and its utility in wheat breeding was confirmed.

In particular, information is lacking to constrain spatial variability associated with GHG emissions (CH sub(4), CO sub(2), and N sub(2)O). GHG fluxes typically vary with edaphic, hydrologic, biologic, and climatic factors. In the PPR, characteristic wetland plant communities integrate hydropedologic factors and may explain some variability associated with trace gas fluxes at ecosystem and landscape scales. We addressed this question for replicate wetland basins located in central North Dakota stratified by hydropedologic vegetation zone on Jul 12 and Aug 3, 2003. Data were collected at the soil- atmosphere interface for six plant zones: deep marsh, shallow marsh, wet meadow, low prairie, pasture, and cropland. Controlling for soil moisture and temperature, CH sub(4) fluxes varied significantly with zone (p < 0.05). Highest CH sub(4) emissions were found near the water in the deep marsh (277,800 kg m super(- 2) d super(- 1) CH sub(4)), which declined with distance from water to - 730 kg m super(- 2) d super(- 1) CH sub(4) in the pasture. Carbon dioxide fluxes also varied significantly with zone. Nitrous oxide variability was greater within zones than between zones, with no significant effects of zone, moisture, or temperature. Data were extrapolated for a 205.6 km super(2) landscape using a previously developed synoptic classification for PPR plant communities. For this landscape, we found croplands contributed the greatest proportion to the net GHG source strength on Jul 12 (45,700 kg d super(- 1) GHG-C equivalents) while deep marsh zones contributed the greatest proportion on Aug 3 (26,145 kg d super(- 1) GHG-C equivalents). This was driven by a 30-fold reduction in cropland N sub(2)O-N emissions between dates. The overall landscape average for each date, weighted by zone, was 462.4 kg km super(- 2) d super(- 1) GHG-C equivalents on Jul 12 and 314.3 kg km super(- 2) d super(- 1) GHG-C equivalents on Aug 3. Results suggest GHG fluxes vary with hydropedologic soil zone, particularly for CH sub(4), and provide initial estimates of net GHG emissions for heterogeneous agricultural wetland landscapes.

Ultrathin-sectioned cell pellets contained icosahedral particles of about 45 nm in diameter. Samples collected from CsCl density gradients revealed mostly non-tailed icosahedral but also tailed particles. The icosahedral particles could be divided into two types: a large type (about 45 nm) and a small type (about 30 nm). Filamentous phage-like particles (17 120 to 6,300 nm) were also observed. The presence of different types of phage-like particles resembling to those in several bacteriophage families provides new physical evidence, in addition to X. fastidiosa genomic information, that X. fastidiosa possesses active phages. This is the first report of phage particles released in X. fastidiosa cultures.

Several other species have been discovered in ticks and animals, and recent reports suggest that some of these Ehrlichia species might be human pathogens. We report here the first association of a recently discovered pathogen, the Panola Mountain Ehrlichia species, with a case of human illness. Case presentation A 31-year-old man from Atlanta, Georgia (GA) in the United States of America (USA) presented with a persistent sore neck of 3 weeks duration following a tick bite. DNA from the Panola Mountain Ehrlichia species, which was recently discovered in a goat in Georgia, was detected in an acute blood sample. Serologic testing was inconclusive. Polymerase chain reaction tests for other tick-borne diseases found in this region were negative. The patient rapidly improved in response to doxycycline therapy. Conclusion Detection of Ehrlichia DNA in an acute blood sample meets the Centers for Disease Control and Prevention laboratory confirmation criteria for ehrlichiosis, and response to doxycycline provides supporting clinical evidence. The Panola Mountain Ehrlichia species, an emerging pathogen transmitted by ticks in the eastern USA, should be considered as a possible cause of tick-borne illness in this region.

We hoped to intervene in C. jejuni gut colonization by using a defined probiotic. Chicken intestinal contents were screened for diverse bacterial isolates that manifested C. jejuni inhibition. These antagonistic bacteria were fed directly to chickens before or after C. jejuni challenge. The prophylactic probiotic treatments were effective only when very low challenge levels of C. jejuni were used. Otherwise, probiotic treatments failed to reduce C. jejuni colonization. Regardless of treatment, as birds further aged C. jejuni numbers soon approached the levels observed in the control birds. We sought an alternative approach, as commercial broilers may be exposed to infectious levels of C. jejuni at any time during production. Two of our most promising antagonistic isolates, Lactobacillus salivarius NRRL B-30514 and Paenibacillus polymyxa NRRL B-30509, were further studied for effectiveness in reducing C. jejuni in chickens. When 250 mg of purified bacteriocins (produced by these organisms)/kg feed were fed therapeutically to chickens colonized with C. jejuni, colonization was reduced by at least one million-fold. Treatments with viable probiotic bacterial cultures were ineffective in reducing C. jejuni in chickens, while bacteriocin treatment from these corresponding bacteria substantially reduced C. jejuni colonization in the live birds.

Applications include feedstock characterization and quantification of structural changes resulting from genetic modification and of the intermediates formed during enzymatic and chemical processing; development of improved processes for utilizing chemical coproducts such as lactic acid and glycerol; development of alternative biofuels such as methanol, butanol, and hydrogen; and ways to reduce greenhouse gas emission and/or use carbon dioxide beneficially. Chemists will also be heavily involved in detailing the phytochemical composition of alternative energy crops and genetically improved crops. A resurgence of demand for agricultural chemistry and related disciplines argues for increasing output through targeted programs and on-the-job training.

As nearly all of these proteins are not found in prokaryotes, the prokaryotic origin of eukaryotic cytoskeletal network suggested by most models is questionable. Eukaryotic cytoskeletal proteins might descend from subpopulations of pre-cells co-existing with Bacteria and Archaea prior to the origin of eukaryotes. The pre-karyote (the host for alpha -proteo bacterial ancestors of mitochondria) might have already possessed eukaryotic-like cytoskeleton. A possible role for viruses in the origin of eukaryotic cytoskeletal proteins is discussed. Viruses parasitizing on pre-cells and/or on the pre-karyote might have themselves used several eukaryotic-like cytoskeletal proteins for segregation and packing of their genomes.

Unfortunately, it has been demonstrated that data loss that occurs when AMs are not worn by subjects (removals during sleeping and waking hours) tend to result in biased estimates of PA and total energy expenditure (TEE). No study has reported the degree of data loss in a large study of adults, and/or the degree to which the estimates of PA and TEE are affected. Also, no study in adults has proposed a methodology to minimize the effects of AM removals. Methods Adherence estimates were generated from a pool of 524 women and men that wore AMs for 13 - 15 consecutive days. To simulate the effect of data loss due to AM removal, a reference dataset was first compiled from a subset consisting of 35 highly adherent subjects (24 HR; minimum of 20 hrs/day for seven consecutive days). AM removals were then simulated during sleep and between one and ten waking hours using this 24 HR dataset. Differences in the mean values for PA and TEE between the 24 HR reference dataset and the different simulations were compared using paired t-tests and/or coefficients of variation. Results The estimated average adherence of the pool of 524 subjects was 15.8 plus or minus 3.4 hrs/day for approximately 11.7 plus or minus 2.0 days. Simulated data loss due to AM removals during sleeping hours in the 24 HR database (n = 35), resulted in biased estimates of PA (p & 0.05), but not TEE. Losing as little as one hour of data from the 24 HR dataset during waking hours results in significant biases (p & 0.0001) and variability (coefficients of variation between 7 and 21%) in the estimates of PA. Inserting a constant value for sleep and imputing estimates for missing data during waking hours significantly improved the estimates of PA. Conclusion Although estimated adherence was good, measurements of PA can be improved by relatively simple imputation of missing AM data.

During adaptation to transkingdom parasitism in diverse plant and insect hosts, phytoplasma evolution has given rise to widely divergent lineages. Since phytoplasmas cannot be cultured in a cell- free medium, measurable phenotypic characters suitable for conventional microbial classification are mostly inaccessible. Currently, phytoplasma differentiation and classification are mainly dependent on restriction fragment length polymorphism (RFLP) analysis of 16S rRNA gene sequences. Extending our recent efforts in the exploitation of computer-simulated 16S rRNA gene RFLP analysis and virtual gel plotting for rapid classification of phytoplasmas, we have developed a Perl program for automated RFLP pattern comparison and similarity coefficient calculation. This program streamlines virtual RFLP pattern analysis and has led to the establishment of a criterion for phytoplasma 16Sr subgroup classification and to the delineation of new and distinct subgroup lineages in the clover proliferation phytoplasma group (16SrVI).

Comparative and phylogenetic analyses of 16S rRNA gene sequences indicated that an overwhelming majority of the cactus-infecting phytoplasmas under study belonged to the peanut witches'-broom phytoplasma group (16SrII). Genotyping through use of computer-simulated restriction fragment length polymorphism (RFLP) analysis of 16S rRNA genes revealed a remarkable genetic diversity among these cactus-infecting phytoplasma strains. Based on calculated coefficients of RFLP pattern similarities, seven new 16SrII subgroups were recognized, bringing the total of described group 16SrII subgroups to 12 worldwide. Geographical areas differed from one another in the extent of genetic diversity among cactus-infecting phytoplasma strains. The findings have implications for relationships between ecosystem distribution and the emergence of group 16SrII subgroup diversity.

The RTD N terminus is highly conserved in luteovirids and this study sought to identify biologically active sites within this region of the PLRV RTD. Fourteen three-amino-acid- deletion mutants were generated from a cloned infectious PLRV cDNA and delivered to plants by Agrobacterium inoculations. All mutant viruses accumulated locally in infiltrated tissues and expressed the readthrough protein (RTP) containing the CP and RTD sequences in plant tissues; however, when purified, only three mutant viruses incorporated the RTP into the virion. None of the mutant viruses were aphid transmissible, but the viruses persisted in aphids for a period sufficient to allow for virus transmission. Several mutant viruses were examined further for systemic infection in four host species. All mutant viruses, regardless of RTP incorporation, moved systemically in each host, although they accumulated at different rates in systemically infected tissues. The biological properties of the RTP are sensitive to modifications in both the RTD conserved and variable regions.

We conducted laboratory experiments to examine the influence of these two processes in addition to N oxide gas production on N availability for 180 d following manure addition. A Tara loam (fine-silty, mixed, superactive, frigid Aquic Hapludoll) and a Webster clay loam (fine-loamy, mixed, superactive, mesic Typic Endoaquoll) amended with liquid dairy (Bos taurus) manure (LD) were incubated at 25 and 10 degree C, while Tara soil amended with solid dairy manure (SD) and turkey (Meleagris gallopavo) manure (T), and Webster soil amended with liquid hog (Sus scrofa) manure (H), were incubated at 25 degree C. Maximum net N immobilization was 14 and 40% of the initial NH sub(4) super(+) concentration in H and LD, respectively, and persisted for 35 to 180 d. In LD-, H-, and T-amended soils, net manure N mineralization was not apparent, and there was good agreement between initial NH sub(4) super(+) content and available inorganic N from the manure. These data suggest that, for these manure types, estimates of first-season available N would be improved by measuring manure NH sub(4) super(+). In contrast, in soil amended with SD, which had the lowest initial NH sub(4) super(+) content, 22% of organic N was mineralized. Gaseous N losses were <1% of the added N in all treatments. The previously developed model NCSOIL was used to predict plant N availability and NO sub(3) super(-) leaching potential with various manure incorporation dates. Under climate conditions typical of the Upper Midwest, no clear advantage of late fall compared with spring incorporation of manure with regard to N availability could be shown, but NO sub(3) super(-) leaching potential seemed high with early fall incorporation.

Measuring plant-available or total soil metals is typically performed to ensure environmental protection, but these techniques do not quantify which soil phases play important roles in terms of metal release or attenuation. This study assessed the distribution of Cd, Cr, Cu, Mo, Ni, Pb, and Zn associated with soluble/exchangeable, specifically adsorbed/carbonate-bound, amorphous Mn hydroxyoxide-bound, amorphous Fe hydroxyoxide-bound, organically complexed, and residual inorganic phases. Biosolids were applied every 2 yr from 1982 to 2002 (except in 1998) at rates of 0, 6.7, 13.4, 26.8, and 40.3 dry Mg biosolids ha super(-) super(1) to 3.6- by 17.1-m plots. In 2003, 0- to 20-cm and 20- to 60-cm soil depths were collected and subjected to 4 mol L super(-1) HNO sub(3) digestion and sequential extraction. Trace metals were concentrated in the 0- to 20-cm depth, with no significant observable downward movement using 4 mol L super(-1) HNO sub(3) or sequential extraction. The sequential extraction showed nearly all measurable Cd present in relatively mobile forms and Cr, Cu, Mo, Ni, Pb, and Zn present in more resistant phases. Biosolids application did not affect Cd or Cr fractionation but did increase relatively immobile Cu, Mo, and Zn phases and relatively mobile Cu, Ni, and Pb pools. The mobile phases have not contributed to significant downward metal movement. Long-term, repeated biosolids applications at rates considered several times greater than agronomic levels should not significantly contribute to downward metal transport and ground water contamination for soils under similar climatic conditions, agronomic practices, and histories.

Wangshuibai is an FHB-resistant Chinese landrace unrelated to cv. Sumai 3, the most commonly used FHB-resistant source. In all, 139 F sub(6) recombinant inbred lines were developed from a cross between Wangshuibai and an FHB-susceptible cultivar, Wheaton, to map quantitative trait loci (QTL) for wheat resistance to initial infection (type I resistance), spread of FHB symptoms within a spike (type II resistance), and deoxynivalenol (DON) accumulation (type III resistance) in infected grain. The experiments were conducted in a greenhouse at Manhattan, KS from 2003 to 2005. More than 1,300 simple-sequence repeat and amplified fragment length polymorphism markers were analyzed in this population. Five QTL for type I resistance were detected on chromosomes 3AS, 3BS, 4B, 5AS, and 5DL after spray inoculation; seven QTL for type II resistance were identified on chromosomes 1A, 3BS, 3DL, 5AS, 5DL, and 7AL after point inoculation; and seven QTL for type III resistance were detected on chromosomes 1 A, 1BL, 3BS, 5AS, 5DL, and 7AL with the data from both inoculation methods. These QTL jointly explained up to 31.7, 64, and 52.8% of the phenotypic variation for the three types of FHB resistance, respectively. The narrow-sense heritabilities were low for type I resistance (0.37 to 0.41) but moderately high for type II resistance (0.45 to 0.61) and type III resistance (0.44 to 0.67). The QTL on the distal end of 3BS, 5AS, and 5DL contributed to all three types of resistance. Two QTL, on 7AL and 1A, as well as one QTL near the centromere of 3BS (3BSc), showed effects on both type II and type III resistance. Selection for type II resistance may simultaneously improve type I and type III resistance as well. The QTL for FHB resistance identified in Wangshuibai have potential to be used to pyramid FHB-resistance QTL from different sources.

Using radiotelemetry, seven snakes (3 females, 4 males) were relocated a total of 363 times from April 2004 to May 2005, resulting in 201 unique locations. Snakes selected trees containing cavities and used hardwoods and snags for a combined 95% of arboreal locations. Texas Ratsnake arboreal activity peaked during July and August, well after the peak of avian breeding activity, suggesting arboreal activity involves factors other than avian predation.

For the 17 insecticides evaluated for laboratory-reared cotton fleahoppers, bifenthrin (pyrethroid), dicrotophos (organophosphate), thiamethoxam (neonicotinoid), and methomyl (carbamate) were the most toxic insecticides in their respective insecticidal classes based on LC sub(50) values. There were significant differences between the LC sub(50) values for the insecticides tested within each of the four insecticidal classes. There were 13-, 46-, 58- , and 31-fold differences between LC sub(50) values for the insecticides within the pyrethroid, organophosphate, neonicotinoid, and carbarmate classes, respectively. Among fleahoppers collected from horsemint in May/June, adult vial testing showed increased susceptibility in males versus females. This difference can be attributed, at least in part, to differences in insect weights between the males and females since the females weighed significantly more than the males. Data presented herein provide a measure of acute potency of various insecticides against P. seriatus and serve as a measure of inherent relative differences between the insecticides. Baseline data will be useful for future comparison should suspicion of tolerance to these insecticides develop in field populations. These data are also important in comparing results from laboratory and field studies with cotton fleahoppers.

Irrigated cropping, particularly in the western USA, is an important source of N sub(2)O emissions. However, the impacts of tillage intensity and N fertilizer amount and type have not been extensively studied for irrigated systems. The DAYCENT biogeochemical model was tested using N sub(2)O, crop yield, soil N and C, and other data collected from irrigated cropping systems in northeastern Colorado during 2002 to 2006. DAYCENT uses daily weather, soil texture, and land management information to simulate C and N fluxes between the atmosphere, soil, and vegetation. The model properly represented the impacts of tillage intensity and N fertilizer amount on crop yields, soil organic C (SOC), and soil water content. DAYCENT N sub(2)O emissions matched the measured data in that simulated emissions increased as N fertilization rates increased and emissions from no-till (NT) tended to be lower on average than conventional-till (CT). However, the model overestimated N sub(2)O emissions. Lowering the amount of N sub(2)O emitted per unit of N nitrified from 2 to 1% helped improve model fit but the treatments receiving no N fertilizer were still overestimated by more than a factor of 2. Both the model and measurements showed that soil NO sub(3) super(-) levels increase with N fertilizer addition and with tillage intensity, but DAYCENT underestimated NO sub(3) super(-) levels, particularly for the treatments receiving no N fertilizer. We suggest that DAYCENT could be improved by reducing the background nitrification rate and by accounting for the impact of changes in microbial community structure on denitrification rates.

Herein, we describe a soil archive at the USDA-ARS Northern Great Plains Research Laboratory (NGPRL) near Mandan, ND with the intent of encouraging research collaboration through utilization of the archive. Over 5000 samples are included in the NGPRL soil archive, ranging in age from 4 to 90 yr. Samples were derived from both grazing and cropping studies, with the former being conducted near Mandan, and the latter as a part of an evaluation of soil C and N change at multiple locations throughout the Great Plains. Most samples are associated with soil depths above 30.5 cm, although 10 locations from the Great Plains evaluation possess archived soils below 1 m for native vegetation treatments. Collaborative research opportunities using the NGPRL soil archive abound, and may include characterizations of soil organic matter fractions, micronutrients, and soil acidity. Scientists interested in engaging in collaborative research efforts are encouraged to contact the authors of this report.

How soil organic matter and its different fractions respond to management has not been comprehensively studied in integrated crop- livestock systems. We conducted a 3-yr field experiment on a Typic Kanhapludult in Georgia in which long-term pasture was terminated and converted to annual crops. Tillage systems were conventional (CT, moldboard plowed initially and disked thereafter) and no-till (NT). Cropping systems were summer grain with winter cover crop and winter grain with summer cover crop. Cover crops were either grazed by cattle or left unharvested. Total organic C was highly stratified with depth under NT and relatively uniformly distributed with depth under CT. All soil C and N fractions were greater under NT than under CT at a depth of 0 to 6 cm. Tillage system had the most dominant influence on all soil C and N fractions, and cropping system the least. At the end of 3 yr, total organic C at a depth of 0 to 30 cm was lower under CT than under NT (42.6 vs. 47.4 Mg ha super(-1) [P < 0.001]). Potential C mineralization was also lower under CT than under NT (1240 vs. 1371 kg ha super(-1) during 24 d [P = 0.02]). At a depth of 0 to 30 cm, cover crop management had no effect on soil C and N fractions, but within the surface 6 cm some changes occurred with grazing of cover crops by cattle, the most dramatic of which were 1 plus or minus 9% increase in soil microbial biomass C and 3 plus or minus 16% decrease in potential C mineralization. To preserve high surface-soil C and N fractions and total plow-layer contents, NT cropping following termination of perennial pasture is recommended. In addition, since cattle grazing cover crops did not consistently negatively influence soil C and N fractions, integrated crop-livestock systems are recommended as a viable conservation approach while intensifying agricultural land use.

Our objectives were to estimate greenhouse gas (GHG) emission reductions from implementation of aerobic technology in USA swine farms. Emission reductions were calculated using the approved United Nations framework convention on climate change (UNFCCC) methodology in conjunction with monitoring information collected during full-scale demonstration of the new treatment system in a 4360-head swine operation in North Carolina (USA). Emission sources for the project and baseline manure management system were methane (CH sub(4)) emissions from the decomposition of manure under anaerobic conditions and nitrous oxide (N sub(2)O) emissions during storage and handling of manure in the manure management system. Emission reductions resulted from the difference between total project and baseline emissions. The project activity included an on-farm wastewater treatment system consisting of liquid-solid separation, treatment of the separated liquid using aerobic biological N removal, chemical disinfection and soluble P removal using lime. The project activity was completed with a centralized facility that used aerobic composting to process the separated solids. Replacement of the lagoon technology with the cleaner aerobic technology reduced GHG emissions 96.9%, from 4972 tonnes of carbon dioxide equivalents (CO sub(2)-eq) to 153 tonnes CO sub(2)-eq/year. Total net emission reductions by the project activity in the 4360-head finishing operation were 4776.6 tonnes CO sub(2)-eq per year or 1.10 tonnes CO sub(2)-eq/head per year. The dollar value from implementation of this project in this swine farm was US$19,106/year using current Chicago Climate Exchange trading values of US$4/t CO sub(2). This translates into a direct economic benefit to the producer of US$1.75 per finished pig. Thus, GHG emission reductions and credits can help compensate for the higher installation cost of cleaner aerobic technologies and facilitate producer adoption of environmentally superior technologies to replace current anaerobic lagoons in the USA.

Carbohydrate Polymers], average demethylated blocks size ([View the MathML source]), average number of demethylated blocks per molecule ([View the MathML source]) and enzyme mode of action were characterized for a series of pectins using a limited digest with endo-polygalacturonase (EPG) to release demethylated blocks (DMBs) from each demethylated pectin. Rheology and calcium sensitivity measurements, on the same series of pectins, are presented herein to relate [View the MathML source] and [View the MathML source] values to functional properties. For the pH 4.5 - 50% DM sample with an excised [View the MathML source] and [View the MathML source], greater than 95% of the molecules appeared to be crosslinked with calcium ion and a storage modulus (G') value of 7.31 Pa was observed. For the pH 4.5 - 70% DM. The data indicated that for the pH 7.5 series, block number could be a limiting factor. The excised block size for the pH 7.5-60% DM sample was comparatively large at 12.2 compared to the pH 4.5 series. In contrast, block number of at least 2.0 appeared to be required before a significant level of calcium sensitivity was observed in the pH 7.5 series. Mixing the pH 4.5 - 70% DM sample with narrow-range size-classes of oligogalacturonic acids (OGalA) showed that small galacturonic acid oligomers with a degree of polymerization (DP) less than 13 could lower yield point (YP) and affect gelation, suggesting that even small excised DMBs need to be considered when relating pectin block size to functional properties.

Effect of pH on demethylated block size, block number and enzyme mode of action AN - 19408154; 8752256 AB - A model homogalacturonan (HG) was used to produce a demethylated series by reacting it with a citrus salt-independent pectin methylesterase (PME) at pH 4.5 and 7.5. HGs with a predicted degree of methylesterification (DM) of 90%, 80%, 70%, 60% and 50% were produced. HG structural properties and PME mode of action were probed by performing a limited digest with an endo- polygalacturonase. Liberated demethylated blocks (DMB) were separated and quantified by HPAEC coupled to an evaporative light scattering detector. A significant increase in maximum and average size of released DMBs was observed between 80% and 70% DM at pH 7.5 and between 70% and 60% at pH 4.5. The observed distribution of fragment lengths was compared to theoretical modeled distributions. A multiple-attack mechanism with a degree of processivity (p) of p = 1 at pH 4.5 and p = 10 at pH 7.5 modeled the observed shorter fragments well, while in all cases the amount of larger fragments detected was more successfully described by a single-chain mechanism.

Generally, management on reserved lands attempts to protect species associated with older forests. Whereas management in matrix lands emphasizes timber production, it maintains some protections for species associated with older forests. We conducted surveys at randomly selected points within the range of the Scott Bar Salamander (Plethodon asupak) and the southern portion of the range of the Siskiyou Mountains Salamander (P. stormi). We conducted surveys on both reserved and matrix lands to assess the relative role that these allocations play in the long-term persistence of Plethodon salamanders in this region. At low elevations (<1219 m), the proportion of sample points with captures of Plethodon spp. was significantly higher in matrix lands than on reserved lands. However, the number of Plethodon spp. captured at matrix and reserved land points was similar. Matrix land mitigations may be essential to provide protection for salamanders with small ranges and limited dispersal abilities. Oregon Ensatina (Ensatina eschscholtzii), the 2nd most commonly encountered amphibian, was more evenly distributed across the landscape than Plethodon spp. and was not associated with either reserved nor matrix lands.

We compared species-specific visitation and contact rates of mammals to 11 candidate feral swine attractants at scent stations using motion-sensing digital photography to identify promising attractants. We found feral swine had greater visitation rates to apple and strawberry stations than to control stations. We recommend managers consider using strawberry attractants for feral swine-specific applications. If, however, a general feral swine attractant is needed, then apple, berry, or caramel attractants may perform well.

Physical barriers to prairie dogs can be used to minimize human--wildlife conflicts. We evaluated 17 existing barriers in the Fort Collins and Boulder, Colorado, areas. Most barriers were made of a single row of vinyl material; these barriers sustained high levels of damage, primarily from wind, and were frequently breached by prairie dogs digging underneath them. Barriers that included a vegetation and a vinyl barrier or a double-vinyl barrier were wind damaged and breached less frequently than the single-vinyl barriers. Sturdy panels of corrugated metal or fiberglass, extending about 76 cm above and 76 cm below the ground surface, were not damaged by wind and were rarely breached by prairie dogs. These barriers were about twice the cost of the single-vinyl barriers, but were much more durable and more effective in preventing prairie dog colony expansion.

However, not all fences exclude hazardous mammals reliably, and effective fences can be too expensive for small airports to purchase and maintain. In this study, we evaluated fencing at 10 small airports in Indiana and documented the presence and relative abundance of wildlife within airport boundaries using remote cameras and spotlight surveys. Only 4 airports were completely fenced, and four were <50% fenced. All airports had openings in their fence lines that would allow hazardous wildlife access to the airfields. We encountered either white-tailed deer (Odocoileus virginianus) or coyotes (Canis latrans) at nine of the airports with remote cameras and during spotlight surveys. There were fewer coyotes and white-tailed deer encountered during spotlight surveys at completely-fenced airports (x = 0.40 individuals/km across 8 surveys; SE = 0.24) than were encountered at airports that were not completely fenced (x = 6.15; SE = 2.32; P = 0.032). Our study suggests that complete enclosure of airfields and regular fence maintenance is vital for effective wildlife-strike management at small airports.

Few studies have been conducted to quantify these effects under controlled conditions and standard rainfall simulation methodologies have not been previously established. In this study, a laboratory rainfall simulation procedure was developed and utilized to evaluate hydrologic and sheet erosional responses to various configurations of impervious surface cover at the small scale. Runoff and sediment losses from a sloped (5%) cascade of soil boxes having 50% impervious cover located at the top of the slope or at the bottom of the slope, or having 0% impervious cover were measured. Results indicate that the 50% upslope impervious treatment generated sediment at 3-5 times the rate of the 50% downslope impervious treatment. Upslope impervious cover resulted in initially lower water runoff rates than channel development, but this effect narrowed or reversed with continued rainfall. These results suggest that upslope impervious surfaces may represent a larger total on-site erosion risk than equivalent impervious surfaces located at lower positions along the slope, especially under high antecedent soil moisture and/or high intensity rainfall.

We used track-plate impressions collected from captured individual martens and fishers of known gender to develop methods to distinguish the gender from tracks. We collected marten tracks from two subspecies M. a. sierrae (tracks n = 54, individuals m = 12, f = 8) and M. a. kumboldtensis (tracks n = 109, individuals m = 10, f = 9). We developed a model for martens which performed extremely well (91-100%) using only total track length. For fishers, we collected 64 tracks (from 7 males, 17 females) and developed a 3-variable model, using interdigital pad height, interdigital pad width, and total track length, which correctly classified 98.6% of the tracks. We evaluated track quality on 129 sheets of contact paper collected during summer (dry-season) and 137 sheets collected during fall (wet-season); 100% of dry season compared to 51% of wet season sheets had suitable quality tracks. Gender discrimination of Martes tracks can be used to investigate gender differences in distribution and habitat (associations), but the generality of these findings to other populations is undetermined.

We used the EPIC model to study impacts of soil and crop management on SOC in corn (Zea mays L.) and soybean (Glycine max L. Merr.) croplands of Iowa. The National Agricultural Statistics Service crops classification maps were used to identify corn- soybean areas. Soil properties were obtained from a combination of SSURGO and STATSGO databases. Daily weather variables were obtained from first order meteorological stations in Iowa and neighboring states. Data on crop management, fertilizer application and tillage were obtained from publicly available databases maintained by the NRCS, USDA-Economic Research Service (ERS), and Conservation Technology Information Center. The EPIC model accurately simulated state averages of crop yields during 1970-2005 (R super(2) = 0.87). Simulated SOC explained 75% of the variation in measured SOC. With current trends in conservation tillage adoption, total stock of SOC (0-20 cm) is predicted to reach 506 Tg by 2019, representing an increase of 28 Tg with respect to 1980. In contrast, when the whole soil profile was considered, EPIC estimated a decrease of SOC stocks with time, from 1835 Tg in 1980 to 1771 Tg in 2019. Hence, soil depth considered for calculations is an important factor that needs further investigation. Soil organic C sequestration rates (0-20 cm) were estimated at 0.50 to 0.63 Mg ha super(-1) yr super(-1) depending on climate and soil conditions. Overall, combining land use maps with EPIC proved valid for predicting impacts of management practices on SOC. However, more data on spatial and temporal variation in SOC are needed to improve model calibration and validation.

This study was conducted to assess the impact of soil type and N fertility on greenhouse gas fluxes (N sub(2)O, CH sub(4), and CO sub(2)) from the soil surface. The soils used were a sandy loam (789 g kg super(-1) sand and 138 g kg super(-1) clay) and a clay soil (216 g kg super(-1) sand, and 415 g kg super(-1) clay). Chamber experiments were conducted using plastic buckets as the experimental units. The treatments applied to each soil type were: (i) control (no added N), (ii) urea-ammonium nitrate (UAN), and (iii) liquid swine manure slurry. Greenhouse gas fluxes were measured over 8 weeks. Within the UAN and swine manure treatments both N sub(2)O and CH sub(4) emissions were greater in the sandy loam than in the clay soil. In the sandy loam soil N sub(2)O emissions were significantly different among all N treatments, but in the clay soil only the manure treatment had significantly higher N sub(2)O emissions. It is thought that the major differences between the two soils controlling both N sub(2)O and CH sub(4) emissions were cation exchange capacity (CEC) and percent water-filled pore space (%WFPS). We speculate that the higher CEC in the clay soil reduced N availability through increased adsorption of NH sub(4) super(+) compared to the sandy loam soil. In addition the higher average %WFPS in the sandy loam may have favored higher denitrification and CH sub(4) production than in the clay soil.

Emissions were monitored from several irrigated cropping systems receiving N fertilizer rates ranging from 0 to 246 kg N ha super(-1) during the 2005 and 2006 growing seasons. Cropping systems included conventional-till (CT) continuous corn (Zea mays L.), no-till (NT) continuous corn, NT corn-dry bean (Phaseolus vulgaris L.) (NT-CDb), and NT corn-barley (Hordeum distichon L.) (NT-CB). In 2005, half the N was subsurface band applied as urea-ammonium nitrate (UAN) at planting to all corn plots, with the rest of the N applied surface broadcast as a polymer-coated urea (PCU) in mid-June. The entire N rate was applied as UAN at barley and dry bean planting in the NT-CB and NT-CDb plots in 2005. All plots were in corn in 2006, with PCU being applied at half the N rate at corn emergence and a second N application as dry urea in mid-June followed by irrigation, both banded on the soil surface in the corn row. Nitrous oxide fluxes were measured during the growing season using static, vented chambers (1-3 times wk super(-1)) and a gas chromatograph analyzer. Linear increases in N sub(2)O emissions were observed with increasing N-fertilizer rate, but emission amounts varied with growing season. Growing season N sub(2)O emissions were greater from the NT-CDb system during the corn phase of the rotation than from the other cropping systems. Crop rotation and N rate had more effect than tillage system on N sub(2)O emissions. Nitrous oxide emissions from N application ranged from 0.30 to 0.75% of N applied. Spikes in N sub(2)O emissions after N fertilizer application were greater with UAN and urea than with PCU fertilizer. The PCU showed potential for reducing N sub(2)O emissions from irrigated cropping systems.

Conversion of plowed fields to pasture has the potential to reverse this process, recapturing organic matter that was lost under more intensive cropping systems. Temperate pastures in the northeast USA are highly productive and could act as significant C sinks. However, such pastures have relatively high biomass removal as hay or through consumption by grazing animals. In addition, the ability to sequester C decreases over time as previously depleted stocks are replenished and the soil returns to equilibrium conditions. The objective of this research was to use eddy covariance systems to quantify CO sub(2) fluxes over two fields in central Pennsylvania that had been managed as pastures for at least 35 yr. Net ecosystem exchange measurements averaged over 8 site-years suggested that the pastures were acting as small net C sinks of 19 g C m super(-2) yr super(-1) (positive values indicate uptake). However, when biomass removal and manure deposition were included to calculate net biome productivity, the pastures were a net source of -81 g C m super(-2) yr super(-1) (negative values indicate loss to the atmosphere). Manure generated from the hay that was consumed off site averaged 18 g C m super(-2) yr super(-1). Returning that manure to the pastures would have only partially replenished the lost C, and the pastures would have remained net C sources. Heavy use of the biomass produced on these mature pastures prevented them from acting as C sinks.

We measured vertical distributions of key microbial, chemical, and physical properties in soils from a long-term tillage experiment and used these data as inputs to a process-based model that accounts for N sub(2)O production, consumption, and gaseous diffusion. The results demonstrate how differences among tillage systems in the stratification of microbial enzyme activity, chemical reactivity, and other properties can control N sub(2)O fluxes. Under nitrification-dominated conditions, simulated N sub(2)O emissions in the presence of nitrite (NO sub(2) super(-)) were 2 to 10 times higher in NT soil compared to soil under conventional tillage (CT). Under denitrification-dominated conditions in the presence of nitrate (NO sub(3) super(-)), higher bulk density and water content under NT promoted higher denitrification rates than CT. These effects were partially offset by higher soluble organic carbon and/or temperature and lower N sub(2)O reduction rates under CT. The NT/CT ratio of N sub(2)O fluxes increased as NO sub(2) super(-) or NO sub(3) super(-) was placed closer to the surface. The highest NT/CT ratios of N sub(2)O flux (>30:1) were predicted for near- surface NO sub(3) super(-) placement, while NT/CT ratios < 1 were predicted for NO sub(3) super(-) placement below 15 cm. These results suggest that N sub(2)O fluxes from RT systems can be minimized by subsurface fertilizer placement and by using a chemical form of fertilizer that does not promote substantial NO sub(2) super(-) accumulation.

Rotation AN - 19375019; 8470280 AB - Intensive agriculture and increased N fertilizer use have contributed to elevated emissions of the greenhouse gases carbon dioxide (CO sub(2)), methane (CH sub(4)), and nitrous oxide (N sub(2)O). In this study, the exchange of CO sub(2), N sub(2)O, and CH sub(4) between a Quincy fine sand (mixed, mesic Xeric Torripsamments) soil and atmosphere was measured in a sweet corn (Zea mays L.)-sweet corn-potato (Solanum tuberosum L.) rotation during the 2005 and 2006 growing seasons under irrigation in eastern Washington. Gas samples were collected using static chambers installed in the second-year sweet corn and potato plots under conventional tillage or reduced tillage. Total emissions of CO sub(2)-C from sweet corn integrated over the season were 2071 and 1684 kg CO sub(2)-C ha super(-1) for the 2005 and 2006 growing seasons, respectively. For the same period, CO sub(2) emissions from potato plots were 1571 and 1256 kg of CO sub(2)-C ha super(-1). Cumulative CO sub(2) fluxes from sweet corn and potato fields were 17 and 13 times higher, respectively, than adjacent non-irrigated, native shrub steppe vegetation (NV). Nitrous oxide losses accounted for 0.5% (0.55 kg N ha super(-1)) of the applied fertilizer (112 kg N ha super(-1)) in corn and 0.3% (0.59 kg N ha super(-1)) of the 224 kg N ha super(-1) applied fertilizer. Sweet corn and potato plots, on average, absorbed 1.7 g CH sub(4)-C ha super(-1) d super(-1) and 2.3 g CH sub(4)-C ha super(-1) d super(-1), respectively. The global warming potential contributions from NV, corn, and potato fields were 459, 7843, and 6028 kg CO sub(2)-equivalents ha super(-1), respectively, for the 2005 growing season and were 14% lower in 2006.

Further study on the effect of elevated CO sub(2) on soil carbon and nitrogen dynamics is key to understanding the potential for long-term carbon storage in soil. Soil samples (0- to 5-, 5- to 10-, and 10- to 20-cm depths) were collected after 2 yr of grain sorghum [Sorghum bicolor (L.) Moench.] production under two atmospheric CO sub(2) levels: (370 [ambient] and 550 mu L L super(-1) [free-air CO sub(2) enrichment; FACE]) and two water treatments (ample water and limited water) on a Trix clay loam (fine, loamy, mixed [calcareous], hyperthermic Typic Torrifluvents) at Maricopa, AZ. In addition to assessing treatment effects on soil organic C and total N, potential C and N mineralization and C turnover were determined in a 60-d laboratory incubation study. After 2 yr of FACE, soil C and N were significantly increased at all soil depths. Water regime had no effect on these measures. Increased total N in the soil was associated with reduced N mineralization under FACE. Results indicated that potential C turnover was reduced under water deficit conditions at the top soil depth. Carbon turnover was not affected under FACE, implying that the observed increase in soil C with elevated CO sub(2) may be stable relative to ambient CO sub(2) conditions. Results suggest that, over the short-term, a small increase in soil C storage could occur under elevated atmospheric CO sub(2) conditions in sorghum production systems with differing water regimes.

We evaluated the 10-yr effects of tillage, cropping system, and N source on crop residue and soil C fractions at 0- to 20-cm depth in Decatur silt loam (clayey, kaolinitic, thermic, Typic Paleudults) in northern Alabama, USA. Treatments were incomplete factorial combinations of three tillage practices (no-till [NT], mulch till [MT], and conventional till [CT]), two cropping systems (cotton [Gossypium hirsutum L.]-cotton-corn [Zea mays L.] and rye [Secale cereale L.]/cotton-rye/cotton-corn), and two N fertilization sources and rates (0 and 100 kg N ha super(-1) from NH sub(4)NO sub(3) and 100 and 200 kg N ha super(-1) from poultry litter). Carbon fractions were soil organic C (SOC), particulate organic C (POC), microbial biomass C (MBC), and potential C mineralization (PCM). Crop residue varied among treatments and years and total residue from 1997 to 2005 was greater in rye/cotton-rye/cotton-corn than in cotton-cotton-corn and greater with NH sub(4)NO sub(3) than with poultry litter at 100 kg N ha super(-1). The SOC content at 0 to 20 cm after 10 yr was greater with poultry litter than with NH sub(4)NO sub(3) in NT and CT, resulting in a C sequestration rate of 510 kg C ha super(-1) yr super(-1) with poultry litter compared with -120 to 147 kg C ha super(-1) yr super(-1) with NH sub(4)NO sub(3). Poultry litter also increased PCM and MBC compared with NH sub(4)NO sub(3). Cropping increased SOC, POC, and PCM compared with fallow in NT. Long-term poultry litter application or continuous cropping increased soil C storage and microbial biomass and activity compared with inorganic N fertilization or fallow, indicating that these management practices can sequester C, offset atmospheric CO sub(2) levels, and improve soil and environmental quality.

Remote sensing represents a potential opportunity to reduce this uncertainty with an in-season assessment of crop N status. This study examines the relationship between EONR and reflectance from a ground-based sensor, and considers its potential for developing sidedress N recommendations for corn. Four fields with unique cropping histories were planted to corn during each of 2 yr. Three preplant whole plot treatments (control, 56 kg N ha super(-1) as NH sub(4)NO sub(3), and manure) were used to create a range of N availability. Split plot treatments included seven sidedress rates (0, 22, 45, 90, 135, 180, and 280 kg N ha super(-1)) and one preplant rate (280 kg N ha super(-1)) as NH sub(4)NO sub(3). The EONR for the sidedress N rates was determined for each whole plot treatment at each site. A ground-based active sensor was used at the sixth- to seventh-leaf growth stage (V6-V7) to collect reflectance data at 590 and 880 nm, which were then used to calculate the Green Normalized Difference Vegetation Index (GNDVI). The EONRs for sidedress N application for the 24 preplant treatment-site combinations ranged from 0 to 202 kg N ha super(-1). The EONR was strongly related to relative GNDVI (r super(2) = 0.84) for the control and manure preplant treatments; but unrelated when NH sub(4)NO sub(3) was applied at planting (r super(2) = 0.20). Developing sidedress N recommendations for corn using an active sensor could be an effective N management tool in Pennsylvania.

The objective of this study was to evaluate water and bromide movement in no-tilled (NT) and conventionally tilled (CT) corn using two different types of in situ lysimeters-pan and capillary wick-for single rainfall events. Four zero-tension pan and four capillary-wick lysimeters were installed 1.2m deep on opposite sides of four soil pits. Two were under NT corn, and two were under CT corn. Bromide (Br) was either surface applied or applied with an initial 25 to 27mm of irrigation (33 to 34gBrm2). A total of 120 to 147mm of irrigation was applied continuously at 8.8mm h-1. Leachate was collected on 15min intervals for 24h and on greater intervals for up to 350h. Lysimeter discharge and Br concentration were determined for each interval. After drainage began and until rainfall was discontinued, the water drainage rate was, on average, greater in NT (7.2mmh-1) than in CT (5.6mmh-1) based on results from the pan lysimeters. By contrast, the water drainage rate for the wick lysimeters was, on average, greater in CT (7.3mmh-1) than in NT (3.0mmh-1). The wick lysimeter appears to have behaved as a sink under the CT conditions, likely representing water flow in smaller channels. Under NT conditions, greater discharge observed with the pan lysimeter implicates the response from larger channels as the conduit for water flow. Flow-weighted mean Br concentration was less when Br was applied on the soil surface (17.9mgL-1) than when Br was applied with the irrigation water (50.6mgL-1). Implications from preferential flow studies are often determined based on a single method of evaluation for solute transport, which are likely subject to the limitation of the method used. This study illustrates that contrary to the conventional understanding about preferential flow in NT, water flow and Br transport to the 1.2-m depth was as great as or greater with CT than with NT based on the results from the wick lysimeters for single rainfall events.

About 13% of these substances were nondigestible carbohydrates, mainly arabinogalactans. The nondigestible high molecular weight ethanol soluble fraction (HESF) of the medium roasted coffee brew was further characterized and subjected to in vitro fermentation with human fecal bacteria. In addition to carbohydrates, HESF contained proteins/peptides ( similar to 20%), but the main fraction was composed of structurally unknown Maillard reaction products. From NMR spectroscopy, we conclude that intact caffeic and ferulic acid derivatives were not incorporated into the melanoidins to a significant extent. Stepwise ultrafiltration and gel filtration indicated a large variation in the molecular weights of HESF constituents. Coffee HESF was shown to be less fermentable by fecal bacteria than soluble coffee fiber isolated by the enzymatic-gravimetric methodology, and because of its lower carbohydrate content, less short-chain fatty acids were produced during the fermentation. Total cell counts, destructive chemical analysis, and NMR spectroscopy indicated that coffee carbohydrates are the preferred substrates for colonic microbiota. However, NMR spectra, absorbances at 405 nm, and nonprotein nitrogen contents showed that noncarbohydrate and nonprotein compounds were also utilized to some extent but the bacterial species involved in this degradation remain to be identified.

Significant ethanol accumulation was only observed in their aerial tissues when severely stressed (water [image] MPa or water [image] g g super(-1) dry mass), with needles accumulating greater quantities than the sapwood or phloem. All species had the same predawn water potentials when sampled, but they were experiencing different levels of stress based on their foliar water contents. Severely stressed Douglas-fir contained higher ethanol and lower water contents (except phloem) than the more drought-tolerant ponderosa pine seedlings. Lodgepole pine with intermediate drought tolerance tended to have intermediate quantities of both components. The mechanistic basis of ethanol accumulation associated with drought stress remains to be determined, especially in larger trees. We speculate that increased levels of in situ ethanol synthesis in seedlings may be associated with heat injury (e.g., membrane damage) due to a reduction in transpirational cooling after stomatal closure. Drought-induced hypoxia may also contribute to ethanol accumulation in the sapwood.

One variable that conversion technologists have wrestled with, particularly in the simultaneous saccharification and fermentation process, is biomass lignin content. While lignin is considered a recalcitrant to biochemical conversion, it can be a good source of combustion fuel, but the true effect of composition on thermochemical conversion has not been well quantified. In this study we examined the effect of lignin content of alfalfa stems on two biofuel conversion methodologies: (i) biochemical conversion using in-vitro ruminal fermentation as a surrogate for fermentability to ethanol and (ii) thermochemical conversion using pyrolysis. Lignin was found to account for little of the variation in pyrolysis product yield compared to biochemical conversion. Linear regression of lignin concentration on pyrolysis product yields resulted in few significant relationships whereas in-vitro gas production exhibited a strong negative response to lignin content. For alfalfa stems, lignin had a much larger effect on biological conversion potential than it did on thermochemical conversion potential. The results suggest that genetic modification or agronomic management of lignocellulosic biomass for bioenergy feedstock composition should be based on the intended energy conversion platform.

Treatments included 50-mL polyethylene centrifuge tubes with gas-release valves (treatment 1); 50-mL polyethylene centrifuge tubes with continuous gassing with CO sub(2) (treatment 2); 50-mL polyethylene centrifuge tubes sealed, oriented horizontally, and shaken continuously parallel to the long axis of the tube, with manual gas release (treatment 3); 125-mL Erlenmeyer flasks with continuous gassing with CO sub(2) (treatment 4); and 125-mL serum vials sealed with stoppers and crimp seals with (treatment 5) or without (treatment 6) manual gas release. Goering and Van Soest medium and blended ruminal inoculum from 4 lactating cows were used. Substrates were alfalfa hay, corn silage, ryegrass hay, and soyhulls. Gas was released and measured in treatments 3 and 6 at 3.0, 5.5, 9.0, 11.5, 23.5, 29.5, and 47.5 h by using a syringe with a hypodermic needle. Vessels from each treatment were harvested at 0, 6, 12, 24, 30, and 48 h for NDF analysis, with NDFD calculated as 1 - [(residual NDF, g - residual NDF in fermentation blank, g)/sample NDF, g]. Medium pH did not decline below 6.3 for any treatment. Average values for NDFD for 24 through 48 h were 0.576, 0.639, 0.688, 0.668, 0.679, and 0.681 for treatments 1 through 6, respectively (standard error of the difference = 0.008). The lowest NDFD was noted for treatment 1, which differed from all other treatments; treatments 3, 4, 5, and 6 did not differ by treatment or by the interaction of treatment and substrate. Treatments 1 and 2 gave lower NDFD values than the other treatments, but these differences were not consistent and differed by substrate, with alfalfa showing the fewest differences among treatments and soyhulls the most. Net energy of lactation values for substrates, as predicted from differences in 48-h NDFD, were 7 to 15% lower for treatment 1 than for the average of all other treatments. Slopes of the gas production per gram of substrate dry matter curves differed between treatments 3 and 5. In conclusion, measured NDFD was altered by fermentation treatment, with polyethylene tubes + gas-release valves giving the lowest values. Consequently, NDFD values may not be comparable across fermentation methods, but the effect will vary among feedstuffs. The combination of methods used for sealing, gassing, or agitating vessels may have a greater impact on NDFD than does vessel type.

However, it is pathogenic only during late summer/early autumn and in certain years. We sampled apparently healthy (n=10) and diarrhoeic (n=10) cattle during an outbreak on a 2000 head dairy in 2003. The following year, monthly faecal (from the same 30 head), total mixed ration, water, and pen soil samples were collected for Salmonella culture. No serogroup, serotype, genetic, or antimicrobial susceptibility differences were observed in comparison of isolates from healthy and sick cattle. During year 2 of the study, Salmonella was routinely cultured (although highly variable from month to month) from the cattle and the environment, although no outbreak of salmonellosis was observed.

The exotic causal agent, Phytophthora ramorum, is an oomycete in the Straminipile group, a relative of diatoms and algae. P. ramorum also infects many popular horticultural plants (i.e. camellia and rhododendron), causing ramorum blight, with symptoms expressed as leaf spots, twig blight and shoot dieback. P. ramorum has raised important biosecurity issues, which continue to reverberate through the agriculture, forestry and horticulture industries as well as associated government management, regulatory and scientific agencies. The continued spread of this and other new Phytophthora spp. presents significant impetus for adjustments in the management and regulation of forest pathogens and nursery stock.

Much of this popularity may be attributed to the non-parametric, multivariate features of the technique, its intuitiveness, and its ease of use. When used with satellite imagery and forest inventory plot data, the technique has been shown to produce useful estimates of many forest attributes including forest/non-forest, volume, and basal area. However, variance estimators for quantifying the uncertainty of means or sums of k-NN pixel-level predictions for areas of interest (AOI) consisting of multiple pixels have not been reported. The primary objectives of the study were to derive variance estimators for AOI estimates obtained from k-NN predictions and to compare precision estimates resulting from different approaches to k-NN prediction and different interpretations of those predictions. The approaches were illustrated by estimating proportion forest area, tree volume per unit area, tree basal area per unit area, and tree density per unit area for 10-km AOIs. Estimates obtained using k-NN approaches and traditional inventory approaches were compared and found to be similar. Further, variance estimates based on different interpretations of k-NN predictions were similar. The results facilitate small area estimation and simultaneous and consistent mapping and estimation of multiple forest attributes.

AN - 69077606; 18044832 AB - Systematic bioassay-guided fractionation of the methylene chloride extract of the roots from Ligularia macrophylla was performed to identify both phytotoxic and antifungal compounds. Four phytotoxic eremophilanes (furanoeremophilan-14beta,6alpha-olide, 6beta-angeloyloxy-10beta-hydroxyfuranoeremophilane, eremophil-7(11)-ene-12,8alpha;14beta,6alpha-diolide, and 3alpha-angeloyloxybakkenolide A) and two antifungal fatty acids (linoleic acid and alpha-linolenic acid) were isolated. The X-ray crystal structure determination of 6beta-angeloyloxy-10beta-hydroxyfuranoeremophilane is reported here for the first time. All four eremophilanes substantially inhibited growth of the monocot Agrostis stolonifera (bentgrass) while demonstrating little activity against the dicot Lactuca sativa (lettuce) at 1000 microM. In a dose-response screening of all compounds for growth inhibitory activity against Lemna paucicostata, 6beta-angeloyloxy-10beta-hydroxyfuranoeremophilane was the most active with an IC50 of 2.94+/-0.16 microM. This compound also caused the greatest reduction of photosynthetic electron flow; however, its mode of action remains to be determined. Evaluation of isolated compounds for activity against the Formosan subterranean termite, Coptotermes formosanus, is also reported. At a concentration of 0.5% (wt/wt), 6beta-angeloyloxy-10beta-hydroxyfuranoeremophilane significantly reduced the consumption of filter paper by C. formosanus.

AN - 69075428; 18038992 AB - Several lupines (Lupinus spp.) present on western U.S. rangelands contain alkaloids that are teratogenic to livestock and cause congenital birth defects in calves (crooked calf disease). Periodically, large losses of calves due to lupine-induced "crooked calf disease" occur in northern Oregon and eastern Washington state. Five lupine populations from this area representing three species (L. leucophyllus, L. sulfureus, and L. sericeus) were evaluated taxonomically and by gas chromatography/mass spectrometry, and the major alkaloids in each lupine species were identified. The teratogenic alkaloid anagyrine was present in both of the lupine species responsible for the high outbreaks in east-central Washington and northeastern Oregon. However, the alkaloid profiles of the two lupines identified as L. leucophyllus were dissimilar, as were the alkaloid profiles of the two lupines identified as L. sulfureus. Botanical classification is not sufficient to determine potential teratogenicity, and it must be followed by chemical characterization to determine risk to livestock.

AN - 68427700; 17624695 AB - This experiment was designed to determine whether a Bordetella bronchiseptica mutant that does not produce dermonecrotic toxin (DNT) is still capable of predisposing pigs to infection with toxigenic Pasteurella multocida. Three groups of pigs were initially inoculated intranasally with a wild type B. bronchiseptica that produces DNT, an isogenic mutant of B. bronchiseptica that does not produce DNT, or PBS. All pigs were then challenged intranasally with a toxigenic strain of P. multocida 4 days later. P. multocida was recovered infrequently and in low numbers from pigs initially inoculated with PBS, and no turbinate atrophy was present in these pigs. P. multocida was isolated in similar numbers from the pigs initially inoculated with either the wild type or the DNT mutant of B. bronchiseptica, and turbinate atrophy of a similar magnitude was also seen in pigs from both of these groups. Thus, although the DNT has been shown to be responsible for much of the pathology seen during infection with B. bronchiseptica by itself, infection with non-DNT-producing strains can still predispose to secondary respiratory infections with P. multocida.

However, field observations conducted throughout the native range of M. quinquenervia, coupled with replicated laboratory studies, have shown that L. trifida forms unique stem galls on Melaleuca species within the M. leucadendron complex. Melaleuca quinquenervia is an invasive weed in Florida, USA and L. trifida is a candidate biological control agent of that species.

In such cases, long-term management objectives should address the maintenance of desirable community and ecosystem processes through reduction in invasive plant abundance and distribution to acceptable levels. Strategic approaches to invasive plant control should include restoration of critical functional groups, mitigation of environmental stressors and reduction in exotic sources of disturbance to improve biotic resistance of the native community and reduction in invasive plant dominance. Monitoring to assess progress toward management goals is essential to identify needed changes in protocol as more is learned about drivers of community processes.

AN - 70107984; 17917911 AB - The effects of cotton-corn rotation and glyphosate use on levels of soil-borne Aspergillus flavus, aflatoxin and fumonisin contamination in corn and cotton seed were determined during 2002-2005 in Stoneville, Mississippi (USA). There were four rotation systems (continuous cotton, continuous corn, cotton-corn and corn-cotton) for both glyphosate-resistant (GR) and non-GR cultivars-herbicide system arranged in a randomized complete block design with four replications. Aspergillus flavus populations in surface (5-cm depth) soil, sampled before planting (March/April), mid-season June) and after harvest (September), ranged from 1.47 to 2.99 log (10) cfu g(-1) soil in the four rotation systems. Propagules of A. flavus were higher in the continuous corn system compared to the continuous cotton system on three sample dates, and cotton rotated with corn decreased A. flavus propagules in three of nine sample dates. Propagules of A. flavus were significantly greater in plots with GR cultivars compared to non-GR cultivars in three samples. In cotton seed, aflatoxin and fumonisin levels were similar ( or = 20 microg kg(-1)) only in GR cultivar in 2004 and 2005. Fumonisin was higher in non-GR cultivar (4 mg kg(-1)) regardless of rotation in 2004; however, in 2002, 2003 and 2005, aflatoxin and fumonisin levels were similar regardless of rotation and glyphosate. These results indicate the potential for increased aflatoxin and fumonisin levels (1 of 4 years) in corn; however, climatic conditions encountered during this study did not allow for mycotoxin production. In laboratory incubation studies, fairly high concentrations of glyphosate were required to inhibit A. flavus growth; however no short-term effect of soil treatment with glyphosate on A. flavus populations were observed. These data suggest that altered populations of A. flavus or higher aflatoxin concentrations in corn grain were due to indirect effects of the GR cropping system.

AN - 70095539; 18284777 AB - Studies were conducted with codling moth, Cydia pomonella L., to fit cumulative curves for the occurrence of injured fruits and male moth catches in sex pheromone-baited traps as a function of accumulated degree-days after the start of moth flight. Twelve data sets were collected from seven apple, Malus domestica Bordhausen, orchards in Washington State from 2003 to 2006. Cumulative data were grouped across years for orchards either treated with sex pheromone dispensers or untreated and fit to logistic equations for both the first and second generation. No significant differences were found for the cumulative curves of moth flight or egg hatch between pheromone-treated and untreated orchards; thus, these data were combined. These new logistic models for moth flight and egg hatch were compared with a widely used distributed-delay model originally developed in Michigan. The cumulative flight curves for the logistic and distributed-delay models were statistically different (slopes) for the first but not the second generation. Cumulative egg hatch in the logistic model was significantly different from the distributed-delay model (intercepts and slopes) for both generations. Most strikingly, the timing of 50% egg hatch during the first generation was delayed 100 DD in the logistic model. The potential impact of this change in the characterization of codling moth's phenology on the effectiveness of insecticide programs targeting eggs and newly eclosed larvae was examined. Possible explanations for this significant difference between the models are discussed.

AN - 69054438; 17979099 AB - The potential anti-carcinogenic effects of tomatine, a mixture of commercial tomato glycoalkaloids alpha-tomatine and dehydrotomatine (10:1), were examined in the rainbow trout chemoprevention model. Prior to the chemoprevention study, a preliminary toxicity study revealed that tomatine in the diet fed daily at doses from 100 to 2000 parts per million (ppm) for 4 weeks was not toxic to trout. For the tumor study, replicate groups of 105 trout were fed diets containing dibenzo[a,l]pyrene (DBP) alone (224 ppm), (N = 3), DBP plus tomatine at 2000 ppm (N = 2), tomatine alone (N = 2), or control diet (N = 2) for 4 weeks. The fish were then returned to control diet for 8 months and necropsied for histopathology. Dietary tomatine was found to reduce DBP-initiated liver tumor incidence from 37.0 to 19.0% and stomach tumor incidence from 46.4 to 29.4%. Tomatine also reduced stomach tumor multiplicity. The tomatine-containing diets did not induce mortality, change in fish weights, or liver weights. No adverse pathological effects in the tissues of the fish on the tomatine diets were observed. Dose-response and chemopreventive mechanisms for tomatine protection remain to be examined. This is the first report on the anticarcinogenic effects of tomatine in vivo.

AN - 69050546; 18067411 AB - Tristetraprolin (TTP) is a member of the CCCH zinc finger proteins and is an anti-inflammatory protein. Mice deficient in TTP develop a profound inflammatory syndrome with erosive arthritis, autoimmunity and myeloid hyperplasia. TTP binds to mRNA AU-rich elements with high affinity for UUAUUUAUU nucleotides and causes destabilization of those mRNA molecules. TTP is phosphorylated extensively in vivo and is a substrate for multiple protein kinases in vitro. A number of approaches have been used to identify its phosphorylation sites. This article highlights the recent progress and different approaches utilized for the identification of phosphorylation sites in mammalian TTP. Important but limited results are obtained using traditional methods, including in vivo labeling, site-directed mutagenesis, phosphopeptide mapping and protein sequencing. Mass spectrometry (MS), including MALDI/MS, MALDI/MS/MS, liquid chromatography/MS/MS, immobilized metal ion affinity chromatography (IMAC)/MALDI/MS/MS and multidimensional protein identification technology has led the way in identifying TTP phosphorylation sites. The combination of these approaches has identified multiple phosphorylation sites in mammalian TTP, some of which are predicted by motif scanning to be phosphorylated by several protein kinases. This information should provide the molecular basis for future investigation of TTP's regulatory functions in controlling proinflammatory cytokines.

Last updated - 2017-01-18 ER - TY - JOUR T1 - Leaf extracellular ascorbate in relation to O(3) tolerance of two soybean cultivars. AN - 69038263; 17442469 AB - Soybean [Glycine max (L.) Merr.] cultivars Essex and Forrest that exhibit differences in ozone (O(3)) sensitivity were used in greenhouse experiments to investigate the role of leaf extracellular antioxidants in O(3) injury responses. Charcoal-filtered air and elevated O(3) conditions were used to assess genetic, leaf age, and O(3) effects. In both cultivars, the extracellular ascorbate pool consisted of 80-98% dehydroascorbic acid, the oxidized form of ascorbic acid (AA) that is not an antioxidant. For all combinations of genotype and O(3) treatments, extracellular AA levels were low (1-30nmolg(-1) FW) and represented 3-30% of the total antioxidant capacity. Total extracellular antioxidant capacity was twofold greater in Essex compared with Forrest, consistent with greater O(3) tolerance of Essex. The results suggest that extracellular antioxidant metabolites in addition to ascorbate contribute to detoxification of O(3) in soybean leaves and possibly affect plant sensitivity to O(3) injury.

AN - 69006541; 18049769 AB - Flow cytometry (FCM) combined with viability staining is a useful tool in discerning viable bacteria in environmental samples where traditional culture methods may fail. Contamination of aerosol samples with dust and other non-biological particles can interfere with accurate sample analysis and therefore there is a desire to exclude those particles from analysis. Particles were sorted according to their light scattering properties, cultured and isolates obtained. Isolates were cultured in suspension and reanalyzed by flow cytometry. The isolates were also analyzed and identified by DNA sequence analysis. Isolates with statistically similar light scattering properties shared common sequence identification. Isolates exhibited distinct light scattering profiles that roughly correlated with their originating gate, but often the peak of the profile was outside that gate.

AN - 68557373; 18045431 AB - To quantify the effect of enrichment, immunomagnetic separation (IMS), and selective plating procedures on isolation of Shiga-toxigenic Escherichia coli O157 (STEC O157) and non-Shiga-toxigenic Escherichia coli O157 (non-STEC O157) from naturally contaminated bovine faeces. Two broth enrichment times, two IMS strategies, and two selective plating media were evaluated. STEC O157 and non-STEC O157 strains were often isolated from the same faecal specimen and responded differently to the isolation protocols. A large-volume IMS system was more sensitive than a conventional small-volume IMS method, but was also more expensive. STEC O157 was more frequently isolated from 6 h enriched broth and ChromAgar plates containing 0.63 mg l(-1) potassium tellurite (TCA). Non-STEC O157 was more frequently isolated from un-enriched broth and ChromAgar plates without tellurite (CA). The combination of 6-h enrichment in Gram-negative broth containing vancomycin, cefixime and cefsuludin, large volume IMS and selective plating on TCA maximized STEC O157 recovery from naturally contaminated cattle faecal specimens. The pairing of proper enrichment with a specific plating procedure is key for STEC O157 recovery from naturally contaminated bovine faeces. Incorporating tellurite into an E. coli O157 detection strategy may select for the subset of E. coli O157 that contains the Shiga-toxin genes.

AN - 68540654; 17475462 AB - Almond skin polyphenolics (ASP) and vitamin C (VC) or E (VE) inhibit the Cu(2+)-induced generation of conjugated dienes in human low-density lipoprotein (LDL) in a synergistic manner. However, the mechanism(s) by which this synergy occurs is unknown. As modification of apolipoprotein (apo) B-100 is an early, critical step in LDL oxidation, we examined the effects of combining ASP or quercetin and antioxidant vitamins on the oxidation of this moiety as well as on the alteration of LDL conformation and electronegativity (LDL-). In a dose-dependent manner, ASP (0.12-2.0 micromol/L gallic acid equivalents) decreased tryptophan (Trp) oxidation by 6.7-75.7%, increased the generalized polarity (Gp) of LDL by 21.0-81.5% at 90 min and reduced the ratio of LDL- to total LDL (tLDL) by 38.2-83.8% at 5 h. The actions of ASP on these parameters were generally additive to those of VC and VE. However, a 10-25% synergy of ASP plus VC in protecting apo B-100 Trp against oxidation may result from their synergistic interaction in prolonging the lag time to oxidation. ASP and VE acted in synergy to reduce LDL-/tLDL by 24-43%. Quercetin's actions were similar to ASP, though more effective at inhibiting Trp oxidation. Thus, ASP and quercetin reduce the oxidative modification of apo B-100 and stabilize LDL conformation in a dose-dependent manner, acting in an additive or synergistic fashion with VC and VE.

AN - 68526360; 18020682 AB - Nutrients, sediment, and toxics from water sources and the surrounding airshed are major problems contributing to poor water quality in many regions of the Chesapeake Bay, an important estuary located in the mid-Atlantic region of the United States. During the early spring of 2000, surface water samples were collected for pesticide analysis from 18 stations spanning the Chesapeake Bay. In a separate effort from July to September of 2004, 61 stations within several tidal regions were characterized with respect to 21 pesticides and 11 of their degradation products. Three regions were located on the agricultural Delmarva Peninsula: The Chester, Nanticoke, and Pocomoke Rivers. Two regions were located on the more urban western shore: The Rhode and South Rivers and the Lower Mobjack Bay, including the Back and Poquoson Rivers. In both studies, herbicides and their degradation products were the most frequently detected chemicals. In 2000, atrazine and metolachlor were found at all 18 stations. In 2004, the highest parent herbicide concentrations were found in the upstream region of Chester River. The highest concentration for any analyte in these studies was for the ethane sulfonic acid of metolachlor (MESA) at 2,900 ng/L in the Nanticoke River. The degradation product MESA also had the greatest concentration of any analyte in the Pocomoke River (2,100 ng/L) and in the Chester River (1,200 ng/L). In the agricultural tributaries, herbicide degradation product concentrations were more strongly correlated with salinity than the parent herbicides. In the two nonagricultural watersheds on the western shore, no gradient in herbicide concentrations was observed, indicating the pesticide source to these areas was water from the Bay main stem.

AN - 20960844; 8536596 AB - Fruit from six genotypes of autumn olive (Elaeagnus umbellate Thunb.); Brilliant Rose, Delightful, Jewel, Natural 1, Natural 2 and Sweet N Tart; were evaluated for fruit quality, phenolic content, carotenoids, antioxidants, antioxidant capacity, and antioxidant enzyme activity. The fruit soluble solids content (SSC), titratable acids (TA), total carotenoids, and total phenolic content varied with genotypes. Soluble solids content (SSC) in six genotypes of autumn olive ranged from 10.6 to 18.4 %, while titratable acids ranged from 0.79 to 1.29 %. Jewel had the highest SSC and Sweet N Tart had the highest TA. Fructose and glucose were the two predominant sugars, and malic acid was the predominant organic acid found in autumn olive fruit. Jewel and Sweet N Tart cultivars had the highest sugar and organic acid content among the six genotypes. Autumn olive had potent free radical scavenging activities for 2,2-di(4-tert-octylphenyl)-1-picrylhydrazyl (DPPH'), 2,2'-azinobis(3-ethylbenzothiazoline-6-sulfonic acid) diammonium salt (ABTS super(+)'), peroxyl radical (ROO'), superoxide radicals (O super(-) sub(2)'), hydroxyl radicals ('OH), and singlet oxygen ( super(1)O sub(2)). Autumn olive also had high activities of antioxidant enzymes including glutathione peroxidase (GHS-POD), glutathione reductase (GR), superoxide dismutase (SOD), ascorbate peroxidase (AsA-POD), dehydroascorbate reductase (DHAR), and monodehydroascorbate reductase (MDAR). Among the six genotypes, Brilliant Rose and Jewel had the highest levels of antioxidants and antioxidant enzyme activity.

To assess the effects of using prescribed fire in restoration efforts, ant abundance, species richness, and composition were examined pre- and post-burn along the elevation and tree cover gradients encompassed by a pinyon-juniper woodland in a central Nevada watershed. Ants were sampled using pitfall traps in 6 sites for the elevation study and in 2 sites for the tree cover study, representing paired burn and control sites in a randomized block design. Vegetation and ground cover variables were also sampled to determine how variation in ant populations was correlated with differences in vegetation and ground cover. Ant species richness remained unchanged for all treatments. Tree cover had no significant effect on ant populations. Significantly mo re ants were trapped after the burn treatment on burn plots. Variation in ant populations was not directly correlated with any of the vegetation or ground cover variables. According to ANOVA and multivariate analyses, elevation had the greatest effect on changes in ant communities, likely due to increased moisture availability. Our results suggest that management for conservation of sagebrush-steppe ecosystems in this and similar watersheds should include a range of elevations to ensure maximum ant species diversity.

In spite of this awareness, historical forest structure has been little used to expand knowledge of historical fire severity. Here, we used forest structure to predict pre-management era fire severity across three biogeoclimatic zones in eastern Washington State, USA, that contained extensive mixed conifer forests. We randomly selected 10% of the subwatersheds in each zone, delineated patch boundaries, and photo-interpreted the vegetation attributes of every patch in each subwatershed using the oldest available stereo-aerial photography. We statistically reconstructed the vegetation of any patch showing evidence of early selective harvesting, and then classified them as to their most recent fire severity. Classification used published percent canopy mortality definitions and a dichotomized procedure that considered the overstory and understory canopy cover and size class attributes of a patch, and the fire tolerance of its cover type. Mixed severity fires were most prevalent, regardless of forest type. The structure of mixed conifer patches, in particular, was formed by a mix of disturbance severities. In moist mixed conifer, stand replacement effects were more widespread in patches than surface fire effects, while in dry mixed conifer, surface fire effects were more widespread by nearly 2:1. However, evidence for low severity fires as the primary influence, or of abundant old park-like patches, was lacking in both the dry and moist mixed conifer forests. The relatively low abundance of old, park-like or similar forest patches, high abundance of young and intermediate-aged patches, and widespread evidence of partial stand and stand-replacing fire suggested that variable fire severity and non-equilibrium patch dynamics were primarily at work.

This study applied linear spectral unmixing to airborne hyperspectral imagery to estimate the variation in grain sorghum yield. Airborne hyperspectral imagery and yield monitor data recorded from two sorghum fields were used for this study. Both unconstrained and constrained linear spectral unmixing models were applied to the hyperspectral imagery with sorghum plants and bare soil as two endmembers. A pair of plant and soil spectra derived from each image and another pair of ground-measured plant and soil spectra were used as endmember spectra to generate unconstrained and constrained soil and plant cover fractions. Yield was positively related to the plant fraction and negatively related to the soil fraction. The effects of variation in endmember spectra on estimates of cover fractions and their correlations with yield were also examined. The unconstrained plant fraction had essentially the same correlations (r) with yield among all pairs of endmember spectra examined, whereas the unconstrained soil fraction and constrained plant and soil fractions had r-values that were sensitive to the spectra used. For comparison, all 5151 possible narrow-band normalized difference vegetation indices (NDVIs) were calculated from the 102-band images and related to yield. Results showed that the best plant and soil fractions provided better correlations than 96.3 and 99.9% of all the NDVIs for fields 1 and 2, respectively. Since the unconstrained plant fraction could represent yield variation better than most narrow-band NDVIs, it can be used as a relative yield map especially when yield data are not available. These results indicate that spectral unmixing applied to hyperspectral imagery can be a useful tool for mapping the variation in crop yield.

The index was developed based on research in humid, temperate, loamy soils but has not been tested for many other conditions. In this project, we determined the effects of management on SCI, SOC, and other soil properties in semiarid, hot, sandy soils located in the Southern High Plains of western Texas. Agroecosystems studied included native rangeland, conservation grassland, cotton (Gossypium hirsutum L.) and wheat (Triticum aestivum L.) rotations, and high-residue forage sorghum (Sorghum bicolor L.). The sites included irrigated and dryland conditions under conventionally tilled and no-tillage practices. Mean SCI values varied from -1.49 for conventionally tilled dryland cotton to 2.15 for the conservation grassland. All native rangelands and conservation grasslands and no-tillage fields (dryland and irrigated) had positive SCI values, which indicates increasing organic matter levels. In contrast, all of the conventionally-tilled cotton fields had negative SCI values, indicating decreasing organic matter levels. The SCI was most strongly correlated with the residue equivalent value (r = 0.68) as estimated in the Revised Universal Soil Loss Equation but based on measured values and particulate organic matter carbon, POM-C (r = 0.57). The SCI showed which fields had the highest levels of POM-C and which fields used no-tillage or limited tillage from fields that had been aggressively tilled. Additional research is needed to adjust the SCI subfactors to better relate the index with SOC.

The usual point-based approaches for estimating ET, however, do not provide enough data for precision farming applications, whereby irrigation schedules could be customized by crop conditions at sub-field scales. Needed in addition are spatially distributed ET modeling approaches, obtainable only through remote sensing, which can observe ET-related surface properties such as vegetation density and surface temperature. Although research using remote sensing to estimate ET has been pursued for many years, there are still few ground-validated, full-season ET studies at fine spatial scales. In this study, we assessed the ability of a remote sensing model to retrieve daily ET throughout an entire growing season for wheat. Image data with 0.5 m resolution were collected in 2005 over an irrigation scheduling research site in central Arizona (Maricopa). The 1.3 ha study area (FISE05) contained 32 leveled, flood-irrigated plots with treatments for irrigation scheduling, planting density, and fertilization. Daily ET was modeled using a two-source energy balance (TSEB) approach and airborne image observations in visible, near-infrared, and thermal infrared wavelengths for six dates throughout the growing season. Using independent soil water depletion observations, modeled daily ET values were accurate to within 0.4 mm d super(-1) for most of the FISE05 season and sensitive to changes in wheat canopy changes. Late-season ET estimates were less satisfactory, with accuracies to within 1.3 mm d super(-1). The significance of these results was supported by verifying agreement between ground and airborne estimates of vegetation indices, wheat canopy cover, and surface temperature. Results from FISE05 also showed that the value of this particular implementation of ET remote sensing was limited by inadequate temporal sampling, seasonal dependence of vegetation density estimators, and uncertain parameterization for the late-season. In each case, modeled and projected daily ET estimate errors could exceed 1 mm d super(-1). These ET/energy balance results can be improved, however, by revising the vegetation density estimators and by combining episodic high-spatial-resolution image data with continuous high-temporal-resolution ground data.

Irrigation Scheduling Performance, Grain Yield, and Water Use Efficiency AN - 20661389; 8174217 AB - Current irrigation scheduling is based on well-established crop coefficient and reference evapotranspiration procedures to estimate daily crop evapotranspiration (ET sub(C)). Effective irrigation scheduling and efficient irrigation water use can occur when ET sub(C) is calculated with crop coefficients representative of actual crop water use conditions. The objective of this research was to evaluate irrigation scheduling using two approaches to estimate the basal crop coefficient (Kd sub(cb)) during wheat experiments conducted in 2003-2004 and 2004-2005 at Maricopa, Arizona. Each K sub(cb) approach (main treatment) included six subtreatment combinations (three plant densities and two N managements) imposed to create spatial and temporal variations in water use among experimental plots. The first approach (NDVI treatment) estimated K sub(cb) separately for each plot based on normalized difference vegetation index (NDVI) data obtained by frequent canopy reflectance measurements. The second approach (FAO treatment) estimated K sub(cb) uniformly for all plots based on a K sub(cb) curve developed for standard wheat conditions. The K sub(cb) estimates were incorporated within the FAO-56 dual crop coefficient procedures to calculate daily ET sub(C) and root zone soil water depletion (D sub(r)). Plot irrigations were provided when the predicted D sub(r) reached 45% of the available soil water. During both wheat experiments, considerable variations in measured soil water depletion were observed for subtreatments due to differences in crop water use rates. For the FAO treatment, mean absolute percent difference (MAPD) for predicted D sub(r) was 27% and 40% for 2003-2004 and 2004-2005, respectively. Prediction of D sub(r) was improved significantly for NDVI for both experiments where treatment MAPD was 17% (2003-2004) and 18% (2004-2005). Although mean irrigation application efficiency for NDVI (89%) and FAO (88%) was similar for 2003-2004, it was significantly higher for NDVI (86%) than FAO (77%) for 2004-2005. Differences for irrigation scheduling resulted in significantly lower seasonal irrigation water use for the NDVI than FAO treatment, 8% (2003-2004) and 13% (2004-2005), but did not result in appreciable treatment differences for seasonal ET sub(C), final grain yield, and crop water use efficiency (yield per unit ET sub(c)). Consequently, a primary outcome for both experiments was significantly higher irrigation water use efficiency (yield per unit irrigation water) for NDVI than FAO. Incorporating K sub(cb) estimates based on NDVI within existing crop coefficient algorithms provides an opportunity to improve wheat irrigation scheduling strategies for conserving irrigation water while maintaining grain yield potentials.

This study was conducted to measure nutrient transport in runoff as affected by tillage and time following the application of beef cattle or swine manure to a site on which corn (Zea mays L.) was grown. Rainfall simulation tests were initiated 4, 32, 62, 123, and 354 days following land application. Three 30 min simulated rainfall events, separated by 24 h intervals, were conducted at an intensity of approximately 70 mm h super(-1). Dissolved phosphorus (DP), particulate phosphorus (PP), total phosphorus (TP), NO sub(3)-N, NH sub(4)-N, total nitrogen (TN), electrical conductivity (EC), and pH were measured from 0.75 m wide by 2 m long plots. Concentrations of DP, TP, and NH sub(4)-N, in general, declined throughout the year on both the no-till cattle and no-till swine manure treatments. Tillage did not significantly affect concentrations of DP, PP, TP, NH sub(4)-N, or pH on the swine manure treatments, but significant variations in these variables were measured over time. Under no-till and tilled conditions on both the cattle and swine manure treatments, the smallest concentrations of DP, NO sub(3)-N, NH sub(4)-N, and TN occurred on the final test date. The increase in pH of runoff during the study is attributed to the addition of CaCO sub(3) to the rations of beef cattle and swine. Tillage appeared to have less of an impact on runoff nutrient transport from cropland areas than length of time since manure application.

AN - 20607971; 8144712 AB - The Mediterranean fruit fly, Ceratitis capitata (Wiedemann), displays a lek mating system characterized by a high level of female discrimination among potential mates. The basis of female choice is not understood, but recent studies indicate that male exposure to the aroma of certain plant structures or essential oils may increase mating success. In particular, exposure to the aroma of ginger root oil (GRO) enhances male mating frequency, and several sterile-male release programs against C. capitata have incorporated 'aromatherapy' (large-scale exposure of pre-release insects to GRO) to increase the effectiveness of control efforts. We investigated the mechanism underlying female preference for GRO-exposed males. Two sets of experiments were conducted. In the first, we monitored female attraction to (1) freshly killed flies, or (2) paper discs that contained hexane extracts from varying treatments. In these tests, females were sighted more often (1) near GRO-exposed than non-exposed males (even when the males were visually concealed) and (2) near extracts from GRO-exposed than non-exposed males. These findings suggest a 'perfume effect', whereby female mate choice is mediated by olfactory differences. In the second set, we compared (1) mate choice between intact females and females from which both antennae had been surgically removed, and (2) mating success between intact males and males from which both antennae had been surgically removed before GRO exposure. Intact females preferred GRO-exposed males, whereas females lacking both antennae rarely mated and showed no preference between GRO-exposed and non-exposed males. In the opposite treatment (intact females but surgically altered males), GRO-exposed males lacking both antennae mated as frequently as GRO-exposed intact males. These data suggest that female choice was dependent on olfactory perception of male odor but that male mating success did not depend on olfactory perception of GRO aroma, suggesting, in turn, that GRO conferred a mating advantage through an external phenomenon (possibly alteration of cuticular scent) rather than through internal processing (pheromone synthesis).

An alternative view is that stability depends more on dynamics of dominant species than on diversity. We compared inter-annual variability (inverse of stability) of aboveground biomass in paired restored and remnant tallgrass prairies at two locations in central Texas, USA. Data from these two locations were used to test the hypothesis that greater richness and evenness in remnant than restored prairies would reduce variability in aboveground biomass in response to natural variation in rainfall. Restored prairies were chosen to be similar to paired remnant prairies in characteristics other than species diversity that affect temporal variability in biomass. Variability was measured as the coefficient of variation among years (square root of variance/mean; CV), where variance in community biomass equals the sum of variances of individual plant species plus the summed covariances between species pairs. Species diversity over five years was greater by a factor of 2 or more in remnant than restored prairies because richness and evenness were greater in remnant than restored prairies. Still, the CV of community biomass during spring and CV of annual biomass production did not differ consistently between prairie types. Neither the sum of species covariances nor total community biomass differed between prairies. Biomass varied relatively little in restored compared to remnant prairies because biomass of the dominant species in restored prairies (the grass Schizachyrium scoparium) varied less than did biomass of other dominant and sub-dominant species. In these grasslands, biomass response to natural variation in precipitation depended as much on characteristics of a dominant grass as on differences in diversity.

AN - 20586218; 8144711 AB - Codling moths are attracted to acetic acid and to ethyl-(E,Z)-2,4-decadienoate, the pear ester, when presented individually. The attraction to acetic acid is thought to be a food finding behavior, whereas the pear odorant, ethyl-(E,Z)-2,4-decadienoate, may be a host kairomone. We found, in a flight tunnel study, that more male and female codling moths were captured in traps when the compounds were presented together compared to tested separately. The combination of odorants provides a stronger lure for female codling moths than exists with pear ester alone and increases the potential for using lures in managing this pest of pome fruits and walnuts.

Allelic polymorphisms were found in all populations, but not at all loci within each population. Mean genetic diversity across loci within populations ranged from 0.009 plus or minus 0.006 to 0.551 plus or minus 0.073, across populations x = 0.234 plus or minus 0.043. Fifteen individuals from the total sample (8.24%) were heterozygous at 1-4 loci. Two populations exhibited no heterozygosity and the remaining two populations had relative heterozygote proportions of 22.5% and 12.1%. Facultative outcrossing is discussed as an aspect of reproductive plasticity in cheatgrass and as a mechanism promoting the evolution of invasive genotypes.

RESEARCH METHODS AND PROCEDURES: One-year changes in weight and body composition and basal metabolic rate (BMR) were measured in 488 Hispanic children and adolescents. Fat-free mass (FFM) and fat mass (FM) were measured by DXA and BMR by calorimetry. Model specifications include the following: body mass (BM) = FFM + FM, each with a specific energy content, cff (1.07 kcal/g FFM) and cf (9.25 kcal/g FM), basal energy expenditure (EE), kff and kf, and energetic conversion efficiency, eff (0.42) for FFM and ef (0.85) for FM. Total energy cost of weight gain is equal to the sum of energy storage, EE associated with increased BM, conversion energy (CE), and diet-induced EE (DIEE). RESULTS: Sex- and Tanner stage-specific values are indicated for the basal EE of FFM (kff) and the fat fraction in added tissue (fr). Total energy cost of weight gain is partitioned into energy storage (24% to 36%), increase in EE (40% to 57%), CE (8% to 13%), and DIEE (10%). Observed median (10th to 90th percentile) weight gain of 6.1 kg/yr (2.4 to 11.4 kg/yr) corresponds at physical activity level (PAL) = 1.5, 1.75, and 2.0 to a total energy cost of weight gain of 244 (93 to 448 kcal/d), 267 (101 to 485 kcal/d), and 290 kcal/d (110 to 527 kcal/d), respectively, and to a total energy intake of 2695 (1890 to 3730), 3127 (2191 to 4335), and 3551 (2487 to 4930) kcal/d, respectively. If weight gain is caused by a change in PAL alone and PAL sub(0) = 1.5 at baseline t = 0, the model indicates a drop in PAL of 0.22 (0.08 to 0.34) units, which is equivalent to 60 (18 to 105) min/d of walking at 2.5 mph. DISCUSSION: Halting the development or progression of childhood obesity, as observed in these Hispanic children and adolescents, by counteracting its total energy costs will require a sizable decrease in energy intake and/or reciprocal increase in physical activity.

Captive lizards were presented with pairs of patches differing in prey density, substrate color, or substrate texture. When patches differed in initial prey density, giving-up densities were equalized. Patch substrate (color or texture) initially influenced giving-up density, but after the first exposure to the experimental substrates, giving-up densities were equal in subsequent trials. Our results indicate that A. uniparens can accurately assess patch quality for fossorial prey in a manner consistent with the presence of a prescient strategy and that factors other than food density can influence patch use.

Design: Assessments of food cravings before and during a randomized controlled trial of HG and LG diets provided for 6 months. Subjects: Thirty-two healthy, overweight women aged 20-42 years. Measurements: Self-reported food cravings and dietary intake, body weight, weight history and measures of eating behaviors. Results: Foods craved at baseline were more than twice as high in energy density as the habitual diet (3.7 plus or minus 1.5 vs 1.7 plus or minus 0.3 kcal/g; P < 0.001), and on average were lower in protein (P < 0.001) and fiber (P < 0.001) and higher in fat (P = 0.002). There were no statistically significant changes in nutritional characteristics of craved foods after 6 months of ER. There was a significant relationship between reported portion size of craved food consumed at baseline and lifetime high body mass index (r= 0.49, P = 0.005). Additionally, there was a significant association between susceptibility to hunger and craving frequency at baseline, and there were significant relationships between hunger score, craving frequency, strength and percentage of time that cravings are given in to after 6 months of ER. In multiple regression models, subjects who lost a greater percentage of weight craved higher energy-dense foods at month 6 of ER, but also reported giving in to food cravings less frequently (adjusted R super(2) = 0.31, P = 0.009). Conclusion: High energy density and fat content, and low protein and fiber contents were identifying characteristics of craved foods. The relationships between craving variables and hunger score suggest that the relative influence of hunger susceptibility on cravings may be important before and especially after ER. Portion size of craved foods and frequency of giving in to food cravings appear to be important areas for focus in lifestyle modification programs for long-term weight loss.

Hjelmqvist], in Oregon was recently observed. Most of the symptomatic or dead trees were located near roads. The cankers on the lower boles of trees are similar to those caused by species of Phytophthora on other trees in western North America. The cankers in the inner bark were reddish-orange in colour and extended upward from necrotic roots. Phytophthora cambivora (Petri) Buisman was isolated from the cankers; identity was confirmed by morphological comparison with known isolates and internal transcribed spacer sequence analysis. Pathogenicity was confirmed by inoculation of chinquapin seedlings and mature trees. Seven of nine isolates from chinquapin were A2 mating type; 27 of 28 isolates from other hosts in Oregon and Washington were A1 mating type.

BP is pan-tropical and causes losses in all producing areas. WB is found in South America and parts of the Caribbean, while FP is found in Central America and parts of South America. Together, these diseases were responsible for over 700 million US dollars in losses in 2001 (4). Commercial cacao production in West Africa and South Asia are not yet affected by WB and FP, but cacao grown in these regions is susceptible to both. With the goal of providing new disease resistant cultivars the USDA-ARS and Mars, Inc. have developed a marker assisted selection (MAS) program. Quantitative trait loci have been identified for resistance to WB, FP, and BP. The potential usefulness of these markers in identifying resistant individuals has been confirmed in an experimental F sub(1) family in Fxuador.

The experiments were designed to determine the effects of crop cultivar, application method (soil drench versus foliar spray), and phosphonate concentration on the level of effectiveness of a crown rot management strategy using phosphonates. Pumpkin cultivar, treatment (type of fungicide product), phosphonate concentration, and application method significantly influenced the level of Phytophthora crown rot control. Between the two fungicides, only FNX-100 suppressed Phytophthora crown rot in pumpkin. For cv. Phantom, the highest level of control was achieved with the drench application of 3.0% FNX-100 whereas, for cv. Spooktacular, all three concentrations of FNX-100 (1.0, 2.0, and 3.0%, vol/vol) applied as a soil drench suppressed or significantly reduced the severity of crown rot. Additional experiments using zucchini as test plants demonstrated that, at the concentrations tested, FNX-100 was more efficacious than FNX-2500 in controlling Phytophthora crown rot and that zucchini cultivar or FNX-100 concentration did not significantly influence crown rot control with phosphonates. In this study, FNX-100, which is not currently labeled for use in vegetables, provided satisfactory disease control in both pumpkin and zucchini whereas FNX-2500, a foliar fungicide comprised of the phosphate/phosphonates and copper, manganese, and zinc, did not significantly affect disease severity. This study, albeit limited in scope, showed that cultivar selection may play an important role in the successful management of Phytophthora crown rot on cucurbits with phosphonates, information which may be useful in designing additional tests and developing management strategies for pumpkin and zucchini that are grown in the field.

(Sapindaceae) was found in plants in Hawaii and Puerto Rico. A fungus associated with cankers was identified as Dolabra nepheliae C. Booth & Ting (1). Numerous black, stipitate, elongate ascomata were produced within cracks of cankers. These ascomata contain elongate, bitunicate asci amid unbranched, interthecial elements and thin, cylindrical, hyaline ascospores measuring 96 to 136 x 2.5 to 3.5 mu m. This fungus was originally described from Malaysia on N. lappaceum (1) and is also known on pulasan (N. mutabile Blume) in Australia (2). Classified by the Food and Agriculture Organization as a 'minor disease', the canker appears to be relatively common in Hawaii and was most likely introduced into Puerto Rico on imported germplasm. Nevertheless, efforts are underway to study the potential damage of this disease as well as mechanisms of control, including introduction of disease resistant clones. Specimens have been deposited at the U.S. National Fungus Collections (Hawaii on Nephelium BPI 878189, Puerto Rico (PR) on Nephelium BPI 878188, and PR on Litchi BPI 878190). Although a specimen of D. nepheliae on L. chinensis was collected from Hawaii in 1984 by G. Wong and C. Hodges and deposited as BPI 626373, this fungus was not known on Nephelium spp. in Hawaii and was not previously known from Puerto Rico on either host.

Methods: Postmenopausal women (N = 239; mean age: 53.8 yr) from Iowa (ISU) and California (UCD) completed the Paffenbarger Physical Activity Questionnaire, which was scored with each method. Dual energy x-ray absorptiometry assessed aBMD at the spine, hip, and femoral neck, and peripheral quantitative computed tomography (pQCT) measured vBMD and bone strength properties at the distal tibia and midshaft femur. Results: UCD women had higher total activity scores and hours per week of leisure activity. All scoring methods were correlated with each other. No method was associated with aBMD. Peak strain score was negatively associated with polar moment of inertia and strength-strain index at the tibia, and total activity score was positively associated with cortical area and thickness at the femur. Separating by geographic site, the peak strain and hip BLE scores were negatively associated with pQCT measures at the tibia and femur among ISU subjects. Among UCD women, no method was significantly associated with any tibia measure, but total activity score was positively associated with measures at the femur (P < 0.05 for all associations). Conclusion: Given the significantly greater hours per week of leisure activity done by UCD subjects, duration may be an important determinant of the effect physical activity has on bone. The positive association between leisure physical activity (assessed by the total activity score) and cortical bone measures in postmenopausal women may indicate a lifestyle factor that can help offset age-related bone loss.

The influences of these factors on the efficacy of the fungal bioherbicides Phomopsis amaranthicola and Microsphaeropsis amaranthi against Palmer amaranth (Amaranthus palmeri), smooth pigweed (Amaranthus hybridus), and redroot pigweed (Amaranthus retroflexus) were investigated in greenhouse and field studies under south Texas conditions. Despite plants being given an initial dew period, the bioherbicides, applied individually or in combination, did not cause mortality on any pigweed species in greenhouse or field environments. In greenhouse experiments, fewer than 5% of the leaves in six- to eight-leaf A. palmeri plants developed necrotic lesions within 2 weeks after bioherbicide treatment and only 8% or fewer of the plants developed stem lesions. Disease incidence was significantly higher in A. hybridus and A. retroflexus, with as much as 94% of leaves developing necrosis and 95% of the plants having stem lesions. New leaf production was reduced by biobherbicide treatment in A. hybridus. Combined-pathogen inoculation caused leaf and stem lesions on mature (13 to 36 leaves per plant) A. hybridus and A. retroflexus. Summer and fall field inoculations with M. amaranthi on A. hybridus and A. palmeri produced disease incidence levels similar to or higher than those in greenhouse tests. Infection of A. palmeri by P. amaranthicola increased the peroxidase activity level nearly twofold compared with the controls. Neither pathogen influenced leaf free amino acid content. The high temperatures and low humidity of south Texas and interspecific variation in resistance, possibly linked to peroxidase induction, limited the efficacy of these bioherbicides.

We hypothesized that differences in energy metabolism between nonoverweight and overweight children are attributable to differences in body size and composition, circulating thyroid hormones, sympathetic nervous system, and adrenomedullary activity. A total of 836 Hispanic children, 5-19 y old, participated in 24-h calorimetry, anthropometric, and dual-energy X-ray absorptiometry measurements. Biochemistries were determined by standard techniques. Absolute total EE (TEE) and its components (sleep EE, basal EE, sedentary EE, cycling EE, walking EE, activity EE, nonexercising activity thermogenesis) were higher in overweight children (P = 0.001). Net mechanical energetic efficiency of cycling was lower in overweight children (P = 0.001). Adjusting for body size and composition accounted for differences in TEE, its components, and energetic efficiency. Net carbohydrate and fat utilization did not differ between groups. TEE was independently influenced by sex, Tanner stage, fat free mass, fat mass (FM), fasting serum nonesterified fatty acids (NEFA), leptin, free thyroxine, triiodothyronine, and 24-h urinary norepinephrine and epinephrine. Fat utilization was independently associated with age super(2), sex, FM, fasting serum NEFA, triacylglycerol, adiponectin, leptin, total thyroxine, and free triiodothyronine. Higher EE in overweight children was largely explained by differences in body size and composition, with minor contributions of thyroid and sympathoadrenal systems. Alterations in EE, energetic efficiency, and substrate utilization were not evident in the overweight children.

This 2-year field study examined the feasibility of amending drainage sediment (containing 4.78kgSeg super(-) super(1)) with methionine and casein to enhance volatilization without or with vegetation of Sporobolus airoides. Results show that without organic amendments, rates of Se volatilization were less than 25kgm super(-) super(2)d super(-) super(1) in all plots. After amending the sediment with 71.4mgmethioninekg super(-) super(1) soil, Se volatilization rates were 434+/-107kgm super(-) super(2)d super(-) super(1) in vegetated plots and 289+/-117kgm super(-) super(2)d super(-) super(1) in irrigated bare plots. With the amendment of 572mgcaseinkg super(-) super(1) soil, rates increased to 346+ /-103kgm super(-) super(2)d super(-) super(1) in irrigated bare plots and to 114+ /-55kgm super(-) super(2)d super(-) super(1) in vegetated plots. Both methionine and casein promoted biological remediation of Se via volatilization most effectively during the warmest months.

These losses have caused a steady decline in production and a reduction in bean quality in almost all the cacao-producing areas in the world, especially in small-holder farms in Latin America and West Africa. The most significant diseases are witches' broom, caused by Moniliophtkora perniciosa, which occurs mainly in South America; frosty pod rot, caused by M. roreri, which occurs mainly in Central and northern South America; and black pod disease, caused by several species of Phytophthora, which are distributed throughout the tropics. In view of the threat that these diseases pose to the sustainability of the cacao crop, Mars Inc. and their industry partners have funded collaborative research involving cacao research institutes and governmental and nongovernmental agencies. The objective of this global initiative is to develop short- to medium-term, low-cost, environmentally friendly disease-management strategies until disease tolerant varieties are widely available. These include good farming practices, biological control and the rational or minimal use of chemicals that could be used for integrated pest management (IPM). Farmer field schools are used to get these technologies to growers. This paper describes some of the key collaborative partners and projects that are underway in South America and West Africa.

This study was undertaken to determine (1) if wet and dry day distributions of hourly wind speeds were different, and (2) if different, would using distributions for all days cause errors in predictions of erosive wind energy and wind erosion on dry days. Hourly weather data were obtained from the National Climatic Data Center SAMSON data set at 46 stations in the western U.S. Wind speeds were sorted into 25 classes and a calm class (0 to 0.5 m s super(-1)). After removal of calm periods, distributions were created for all days, dry days, and wet days. The wet days comprised wind speeds from the initial hour of precipitation and the 23 succeeding hours. Among 552 pairs of wet-day and dry-day cumulative monthly wind speed distributions, 87% of the distributions were significantly different (0.10 level or less based on a Kolmogorov-Smirnov test). To determine the importance of these differences, monthly ratios of erosive wind energy were calculated from dry-day and all-day distributions. Over much of the area, the erosive wind energy was lower on dry days than on all days. The eastern Great Plains and eastern Washington had the lowest ratios. Hence, use of an all-day wind speed distribution at these locations likely overestimates potential soil loss from wind erosion. Limited wind erosion simulations using the WEPS model tended to support this conclusion. In contrast, a few of the low-precipitation areas in the west had ratios that were consistently greater than 1. In summary, accuracy of predicted wind erosion from physically based models can be modestly improved by accounting for differences in wind, speed distributions on wet and dry days.

Twenty-four nulliparous yearling Rambouillet-cross ewes (initial BW = 65.1 plus or minus 0.6 kg), surgically fitted with chronic-indwelling catheters in hepatic and portal veins, a mesenteric vein and artery, and the uterine lumen, were assigned to a 2 x 2 factorial arrangement of treatments. Factors were intrauterine bacterial inoculation (noninoculated vs. inoculated) and level of MM [low (2.28 g/d) vs. high (3.91 g/d)]. Beginning 12 h before sampling, inoculated and noninoculated ewes received 10-mL intrauterine infusions of Escherichia coli (9.69 x 10 super(11) cfu) + Arcanobacterium pyogenes (2.76 x 10 super(12) cfu) and of sterile saline, respectively. Uterine infection was induced in ewes that received intrauterine bacterial inoculations, but not in ewes infused with sterile saline. Bacterial inoculation resulted in increased hepatic release and plasma concentrations of aromatic AA used for acute-phase protein synthesis, increased hepatic removal and decreased plasma concentrations of AA used for glutathione synthesis, and decreased plasma concentrations of some gluconeogenic and acetogenic AA used for glucose recycling and anaerobic energy production, respectively (P < 0.05). In ewes fed high-MM diets, compared with low-MM diets, a consistent net hepatic uptake of Phe occurred throughout the sampling period, more Asp was released from the portal-drained viscera, and hepatic vein glucose concentrations were greater (P < 0.05). We conclude that Met seemed to be limiting in low-MM ewes, and as such, would continue to be limiting during sepsis. However, additional MM, in excess of the dietary requirement, would not necessarily result in a benefit to ewes experiencing acute sepsis.

AN - 19993199; 8004843 AB - There are relatively few federal regulations that influence U.S. agricultural production. However, local concerns over environmental quality may influence the management practices on farms. A detailed analysis of corn farms yields insight into this relationship and its implications for the use of cropland best management practices. Our findings suggest that increased contact between working farms and suburban and exurban populations likely increase the use of nutrient management plans, a management-intensive conservation practice. However, nutrient management practices were not found to be associated with waters listed as impaired because of nutrient pollution.

The most common strategy used to generate reliable performance trial data uses experimental design to minimize experimental error resulting from spatial variability. However, an alternative strategy uses a posteriori statistical procedures to account for spatial variability. In this study, the efficiency of the randomized complete block (RCB) design and nearest neighbour adjustment (NNA) were compared in a series of cotton performance trials conducted in the southeastern USA to identify the efficiency of each in minimizing experimental error for yield, yield components and fibre quality. In comparison to the RCB, relative efficiency of the NNA procedure varied amongst traits and trials. Results show that experimental analyses, depending on the trait and selection intensity employed, can affect cultivar or experimental line selections. Based on this study, we recommend researchers conducting cotton performance trials on variable soils consider using NNA or other spatial methods to improve trial precision.

We examined the root crowns and stems of yellow starthistle and related plants growing in five countries (Armenia, Republic of Georgia, Greece, Russia, and Turkey) where yellow starthistle is native. In its native range, the root crowns and lower stems of yellow starthistle are frequently attacked by the internal feeding larvae of apionid weevils. We present illustrations and a key to the adults of the six apionid species that we reared from yellow starthistle and its relatives: Ceratapion basicorne (Illiger), C. carduorum (Kirby), C. gibbirostre (Gyllenhal), C. onopodri (Kirby), C. orientale (Gerstaecker), and C. penetrans (Germar). The only apionid we reared from yellow starthistle was C. basicorne. In Turkey, where we collected most intensively, 58% of the yellow starthistle at 20 sites had larvae of this weevil, and at sites where C. basicorne was present, there were an average of 1.8 immatures per yellow starthistle plant. This apionid is currently being further researched for its potential as a biological control agent for yellow starthistle.

MDV isolates vary greatly in pathogenicity. While some of the strains such as CVI988 are non-pathogenic and are used as vaccines, others such as RB-1B are highly oncogenic. Molecular determinants associated with differences in pathogenicity are not completely understood. Comparison of the genome sequences of phenotypically different strains could help to identify molecular determinants of pathogenicity. We have previously reported the construction of bacterial artificial chromosome (BAC) clones of RB-1B from which fully infectious viruses could be reconstituted upon DNA transfection into chicken cells. MDV reconstituted from one of these clones (pRB-1B-5) showed similar in vitro and in vivo replication kinetics and oncogenicity as the parental virus. However, unlike the parental RB-1B virus, the BAC-derived virus showed inability to spread between birds. In order to identify the unique determinants for oncogenicity and the ''non-spreading phenotype'' of MDV derived from this clone, we determined the full-length sequence of pRB-1B-5. Comparative sequence analysis with the published sequences of strains such as Md5, Md11, and CVI988 identified frameshift mutations in RLORF1, protein kinase (UL13), and glycoproteins C (UL44) and D (US6). Comparison of the sequences of these genes with the parental virus indicated that the RLORF1, UL44, and US6 mutations were also present in the parental RB-1B stock of the virus. However with regard to UL13 mutation, the parental RB-1B stock appeared to be a mixture of wild type and mutant viruses, indicating that the BAC cloning has selected a mutant clone. Although further studies are needed to evaluate the role of these genes in the horizontal-spreading defective phenotype, our data clearly indicate that mutations in these genes do not affect the oncogenicity of MDV.

PVX-expressed CMV CP formed virus-like particles, which served as carriers for heterologous antigens of the Newcastle disease virus (NDV). In this work, we applied our expression tool toward the development of plant-derived vaccine candidate against avian influenza A virus. Twenty-three amino acid-long extracellular domain of the viral M2 protein (M2e) was engineered into the internal motif 5 of CMV CP and the recombinant gene then was transiently expressed in plants through a PVX vector. Chimeric CMV capsids reacted with specific antibodies produced to synthetic M2e epitope of the H5N1 strain of the virus. In addition, CMV CP- M2e protein was expressed to high levels in Escherichia coli bacterial cells and was recognized by antibodies to both CMV and M2e. This initial study demonstrates the feasibility of using plant virus-based vectors for expression of antigenic epitopes of H5N1 avian influenza in plants.

An 80 kW RFEF pasteurizer was used to process pulp-free orange juice at flow rates of 1.0 and 1.4 l/min. Escherichia coli K12 in orange juice was exposed to electric field strengths of 15 and 20 kV/cm at frequencies of 21, 30, and 40 kHz. Ascorbic acid (Vitamin C) content and color of the juice before and after treatment were analyzed. Electrical energy costs were calculated using the measured voltage and current. An energy balance was performed using the inlet and outlet temperatures. Processing at an outlet temperature of 65 degree C reduced the population of E. coli by 3.3 log relative to the control. Increasing the treatment time and temperature and decreasing the frequency enhanced the level of inactivation. Varying the electric field strength over the range of conditions used had no effect on the inactivation. No loss in ascorbic acid or enzymatic browning was observed due to RFEF processing. The electrical energy determined using the voltage and current was 180 J/ml. This was in good agreement with the energy calculated using the temperature data. The electrical cost was $0.0026/l of orange juice. The results provided the first evidence that the RFEF process inactivates bacteria in orange juice at moderately low temperatures. Industrial relevance - The RFEF process has been shown to inactivate E. coli in apple juice at moderately low temperatures, but has yet to be extended to inactivate bacteria in orange juice. An RFEF pilot plant pasteurizer was used to process orange juice at rates of up to 1.4 l/min. RFEF processing reduced the population of E. coli by 99.3% at 60 degree C and a hold time of 3 s, whereas conventional heating at the same conditions had no effect on the E. coli. This work demonstrated that the non-thermal RFEF process can be extended to inactivate bacteria in orange juice.

Historically, diagnosis of tuberculosis has relied largely upon assays of cell-mediated immunity (CMI), such as tuberculin skin testing. This approach, however, is problematic or impractical for use with many wildlife species. Increasingly, in vitro diagnostic tests, including gamma interferon (IFN- gamma )-based assays, are replacing or complementing skin testing of cattle and humans. Analogous assays are unavailable for most wildlife because of a lack of species-specific immunological reagents. This report describes the development and validation of a whole-blood assay to quantify antigen-specific IFN- gamma mRNA expression by quantitative real-time reverse transcription-PCR. Oligonucleotide primers and probes were designed and tested for reactivity towards several susceptible species of interest with respect to tuberculosis infection. The assay was subsequently optimized to quantify the IFN- gamma mRNA expression in elk and red deer (Cervus elaphus) and was evaluated for its ability to detect mycobacterial antigen-specific responses of experimentally tuberculosis-infected animals. The assay was a simple, rapid, and sensitive measure of antigen-specific CMI. The IFN- gamma mRNA responses correlated well with IFN- gamma protein production and showed performance in determining an animal's infection status superior to that of either lymphocyte proliferation or IFN- gamma protein enzyme-linked immunosorbent assay methods. An additional advantage is the ease with which the assay can be modified to reliably quantify IFN- gamma expression by using consensus sequences of closely related species or of other species for which IFN- gamma sequence information is available.

Samples of serum, feces, and tissues from cats from Mona, a remote island off the coast of Puerto Rico, were examined for T. gondii infection. Antibodies to T. gondii were assayed by the modified agglutination test and found in 16 of 19 (84.2%) of cats, with titers of 1:10 in 2, 1:80 in 1, 1:160 in 4, 1:320 in 3, and 1:1,280 or higher in 6. Tissues of 19 of the 20 cats were bioassayed in mice for T. gondii infection. Toxoplasma gondii was isolated from tissues of 12 cats: from the hearts of 9, skeletal muscle of 10, and brain of 1 cat. All infected mice from 10 of 12 isolates died of acute toxoplasmosis during primary infection. Genotyping of these 12 T. gondii isolates (designated (TgCatPr 1-12) by 10 multilocus PCR-RFLP markers, i.e., SAG1, SAG2, SAG3, BTUB, GRA6, c22-8, c29-2, L358, PK1, and an apicoplast marker Apico, and the 6 multilocus microsatellite markers TUB2, W35, TgM-A, B18, B17, and M33, revealed 7 genotypes; 5 isolates had Type I alleles at all loci except at 1 microsatellite locus, and the remainder were atypical. The latter isolates of T. gondii were different biologically and phenotypically from the feline isolates from the rest of the Americas. One isolate (TgCatPr 12) was a mixed infection with 2 genotypes.

Antibodies to T. gondii were found in 32 of 54 (59.2%) raccoons, 18 of 35 (51.4%) coyotes, and 5 of 7 (71.4%) skunks using the modified agglutination test and a cut-off titer of 1:20. Pooled tissues (brains, hearts, and tongues) from 30 raccoons, 15 coyotes, and 1 skunk were bioassayed for T. gondii infection in mice or cats. Viable T. gondii was isolated from 5 of 30 (16.7%) raccoons, 6 of 15 (40.0%) coyotes, and the skunk. Genetic characterization of the 12 parasite isolates by multilocus PCR-RFLP markers revealed 6 different genotypes including 5 atypical and 1 archetypal II lineages. The results indicate the prevalence of T. gondii in wildlife mammals is high and that these animals may serve as an important reservoir for transmission of T. gondii.

In the Canadian prairies, mesocarnivores such as striped skunks (Mephitis mephitis) and raccoons (Procyon lotor) have experienced an increase in density and distribution, and they are in close contact with human dwellings. However, there has been no systematic study on the seroprevalence of T. gondii in these mesocarnivore populations. The objectives of the current project were to determine the serum antibody prevalence of T. gondii in Canadian prairie mesocarnivores and to study the relationship between antibody prevalence and species, sex, age, location, and year of collection. Antibodies to T. gondii were found in 5 of 24 (20.8%) skunks from Saskatchewan trapped in 1999 and 5 of 40 (12.5%) in 2000. Seroprevalences for T. gondii in raccoons and skunks trapped in Manitoba were 2 of 10 (20%) raccoons trapped in 2002, 7 of 44 (15.9%) trapped in 2003, and 16 of 37 (43.2%) trapped in 2004; and in 13 of 99 (13.1%) skunks trapped in 2003, 29 of 131 (22.1%) trapped in 2004, 53 of 165 (32.1%) trapped in 2005, and 30 of 51 (58.8%) trapped in 2006. Age, location, and year, but not the host species, were important variables in the determining the seroprevalence of T. gondii in skunks and raccoons. Results confirm that T. gondii is endemic in the skunk and raccoon populations in the Canadian prairies.

Low- passage isolates were resistant to high levels (>100 mu g/mL) of erythromycin, spiramycin and the lincosamides but were sensitive to dalfopristin, an analogue of streptogramin B. Interestingly, the high-passage erythromycin- resistant strain B31 was resistant to quinupristin, an analogue of streptogramin A (25 mu g/mL). Biochemical analysis revealed that resistance was not due to antibiotic inactivation or energy-dependent efflux but was instead due to modification of ribosomes in these isolates. Interestingly, we were able to demonstrate high-frequency transfer of the resistance phenotype via conjugation from B. burgdorferi to Bacillus subtilis (10 super(-2)- 10 super(-4)) or Enterococcus faecalis (10 super(-5)). An intergeneric conjugal system in B. burgdorferi suggests that horizontal gene transfer may play a role in its evolution and is a potential tool for developing new genetic systems to study the pathogenesis of Lyme disease.

Since aberrant hepatic fatty acid uptake may contribute to this, we investigated whether increased expression of a fatty acid transport protein (CD36) in the liver during DIO contributes to the dyslipidemia that precedes development of type 2 diabetes. RESEARCH DESIGN AND METHODS-We determined the effect DIO has on hepatic CD36 protein expression and the functional consequence of this in terms of hepatic triglyceride storage and secretion. In addition, in vivo adenoviral gene delivery of CD36 to the livers of lean mice was performed to determine if increased hepatic CD36 protein was sufficient to alter hepatic fatty acid uptake and triglyceride storage and secretion. RESULTS:-During DIO, CD36 protein levels in the liver are significantly elevated, and these elevated levels correlate with increased hepatic triglyceride storage and secretion. These alterations in liver lipid storage and secretion were also observed upon forced expression of hepatic CD36 in the absence of DIO and were accompanied with a marked rise in hepatic fatty acid uptake in vivo, demonstrating that increased CD36 expression is sufficient to recapitulate the aberrant liver lipid handling observed in DIO. CONCLUSIONS:-Increased expression of hepatic CD36 protein in response to DIO is sufficient to exacerbate hepatic triglyceride storage and secretion. As these CD36-mediated effects contribute to the dyslipidemia that often precedes the development of type 2 diabetes, increased hepatic CD36 expression likely plays a causative role in the pathogenesis of type 2 diabetes.

This land type has provided a variety of goods and services, with the provisioning of food and fiber dominating through much of the 20th century. More recently, food production from a rangeland-based livestock industry is often pressured for a variety of reasons, including poor economic returns, increased regulations, an aging rural population, and increasingly diverse interests of land owners. A shift to other provisioning, regulating, cultural, and supporting services is occurring with important implications for carbon sequestration, biodiversity, and conservation incentives. There are numerous goods and services possible from rangelands that can supply societal demands such as clean water and a safe food supply. The use of ecologically-based principles of land management remains at the core of the ability of private land owners and public land managers to provide these existing and emerging services. We suggest that expectations need to be based on a thorough understanding of the diverse potentials of these lands and their inherent limits. A critical provisioning service to rangelands will be management practices that either maintain ecological functions or that restore functions to systems that have been substantially degraded over past decades. With proper incentives and economic benefits, rangelands, in the U.S. or globally, can be expected to provide these historical and more unique goods and services in a sustainable fashion, albeit in different proportions than in the past.

Nitrate (NO sub(3)-N) and dissolved reactive phosphorus (DRP) were measured on a golf course in Austin, TX, USA from April 1, 1998 to March 31, 2003. NO sub(3)-N and DRP concentrations measured in storm flow were significantly greater exiting the course compared to those entering the course. Significant differences were also measured in baseflow NO sub(3)-N concentrations. The measured loading from the course was 4.0kg NO sub(3)-Nha super(-) super(1)yr super(-) super(1) (11% of applied) and 0.66kg DRPha super(-) super(1)yr super(-) super(1) (8% of applied). The resulting concentrations contributed by the course were 1.2mgL super(-) super(1) NO sub(3)-N and 0.2mgL super(-) super(1) DRP. At these levels, NO sub(3)-N poses minimal environmental risk. However, the DRP concentration is twice the recommended level to guard against eutrophication.

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.

Treponema phagedenis-like (TPL) spirochetes are a constant feature of PDD lesions and are localized deep in infected tissue. Host-cell response mechanisms to TPL spirochetes are poorly understood. To assess how bovine macrophages respond to cellular constituents of TPL spirochetes, changes in transcription were analyzed using serial analysis of gene expression (SAGE) and real time RT-PCR. This analysis revealed that some proinflammatory cytokines (e.g. GCP-2 and IL-8) are induced in treated macrophages, while receptors and their accessory proteins for IL-1, IL-6 and IL-11 are either down regulated or unchanged. Two genes encoding proteins having negative effects on NF mu B, I mu B and SIVA-1, are significantly induced in stimulated cells. Several genes associated with the cytoskeleton and antigen presentation are down regulated after exposure to sonicated TPL spirochetes, as are genes associated with wound repair. Combined, these data suggest that the innate immune and wound repair functions of bovine macrophages exposed to TPL cellular constituents are impaired thereby enabling bacteria to resist clearance and induce lesion formation. Use of this in vitro bovine macrophage model should be useful in elucidating host-spirochete interactions and facilitate identification of potential virulence traits.

As we have refined and enhanced genetic engineering techniques in several insect species that cause significant economic loss and public health injury, it has become clear that insect biotechnology will move forward as one of the key tools of pest management in agriculture and in the human environment. Well characterized genetic elements can be manipulated toward specific aims and maintain a viable insect, albeit one with diminished capacity to exchange genetic material, vector a virus or bacterium, or complete its life cycle. Despite this degree of knowledge and precision, there remain unanswered questions regarding environmental fate, release and public acceptance of this technology. The uncertainty surrounding any novel technology inevitably increases the level of regulatory scrutiny associated with its use. Although the term 'insect biotechnology' has many connotations, it certainly includes the genetic modification of symbiotic or commensally associated microbes as a means of delivering a trait (e.g. a toxin) to manage plant and human diseases and insect pests. The distinction between this paratransgenic approach and direct genetic modification of insect pests is an important one biologically as well as from a regulatory standpoint. The regulatory framework for microbial applications to agriculture is in many instances in place; however, we must strive to forge the development of guidelines and regulations that will foster deployment of insect biotechnologies.

Here, it is reported that the B. pertussis pertactin gene sequence for the region that encompasses the RT-PCR probe and primers is nearly identical to that of many Bordetella bronchiseptica strains of human and avian origin. Additionally, it is demonstrated that such strains are erroneously identified as B. pertussis using the RT-PCR assay. These data suggest that the use of the assay without confirmatory testing may result in erroneous identification of a significant proportion of human isolates of B. bronchiseptica as B. pertussis.

In small southern communities, to know where someone lives is to know who someone is because place assigns biography. Studies have investigated the physical and economic implications of landscape change in the South, but comparatively little research focuses on the impacts to culture of urban growth. We consider how sense of place (as an indicator of culture) may be impacted, over time, by physical and structural changes in a locale. This point of departure examines the temporal dimension of sense of place, or how place perceptions may vary as familiar places and practices are altered by landscape moderations. We review the literature on sense of place and changing Southern landscapes and also offer a conceptual framework for analyzing sense of place over the long-term.

Despite the great economic importance of D. citri to citrus production, little is known about the reproductive biology and behavior of this insect. We conducted studies to determine the copula duration, the age at which both males and females reach reproductive maturity, the pre-oviposition period, the daily timing of mating activity in a laboratory colony, and the temporal dynamics in the sex ratio of a cohort of newly eclosed adults. The emergence patterns of males and females were strikingly similar, with no evidence for protandry or protogyny. Both sexes reached reproductive maturity by 2-3 d post-eclosion. Oviposition generally began within 1 d after mating, but was longer when females were mated at 2 d of age. Mean plus or minus SEM copula duration was 48.3 plus or minus 8.4 minutes (range: 15.2-98.0). Mating on orange jasmine was observed almost exclusively on flush shoots during daylight hours, with no obvious peak of daily mating activity. Mating activity may be constrained during scotophase in part by cooler temperatures and lack of light. Methods for carrying out mating experiments with this species are described.

Serum samples from 427 dairy cattle and 32 dairy water buffaloes from 7 organized dairy farms located in Punjab, India, were tested for N. caninum antibodies using a commercial monoclonal antibody-based competitive enzyme-linked immunosorbent assay (ELISA). Antibodies to N. caninum were found in 35 of 427 cattle from 6 of the 7 farms; 9.6% of cows, 5.1% of heifers, and 5.0% of calves were seropositive, suggesting postnatal transmission of N. caninum on the farm. Antibodies to N. caninum were found in 16 of 32 buffaloes tested from 2 dairy farms. In total, 64 cattle and 16 buffalo sera already tested by ELISA were also evaluated by an indirect fluorescent antibody test (IFAT) to verify ELISA results. Of the 64 cattle samples, 29 sera were negative by both tests and of the 35 ELISA-positive sera, 12 had IFAT titers of 1:100 or higher (1 had IFAT titer of 100, 2 had IFAT titer of 200, and 9 had IFAT titers of 400 or higher). Of the 16 buffalo sera positive by ELISA, 1 had an IFAT titer of 1:400. Thus, antibodies to N. caninum were demonstrated in cattle sera by 2 serologic methods. To our knowledge this is the first report of N. caninum infection in cattle and buffaloes in India.

Hibernating Louisiana Pine Snakes (Pituophis ruthveni; N = 7) in eastern Texas and Black Pine Snakes (Pituophis melanoleucus lodingi; N = 5) in Mississippi were excavated to characterize their hibernacula. Pituophis ruthveni hibernated exclusively in burrows of Baird's Pocket Gophers (Geomys breviceps), whereas P. m. lodingi hibernated exclusively in chambers formed by the decay and burning of pine stumps and roots. All snakes hibernated singly at shallow depths (P. ruthveni mean = 19 cm, max. = 25 cm; P. m. lodingi mean = 25 cm, max. = 35 cm). Pituophis taxa at higher latitudes and elevations hibernate communally and at greater depths. In contrast to Northern Pine Snakes (Pituophis melanoleucus melanoleucus), none of the pine snakes in our study excavated hibernacula beyond minimal enlargement of the preexisting chambers. These differences are presumably the result of mild winters, an abundance of suitable sites offering sufficient thermal insulation, and reduced predation risk caused by absence of communal hibernation in traditional sites. It is increasingly apparent that, throughout their annual cycle, pine snakes are dependent upon fire-maintained pine ecosystems.

To compensate for lure degradation, a correction factor was applied based on a regression model of relative lure efficiency, expressed as a percent of the catch of a freshly deployed lure as a function of the number of days each set of lures was deployed. The regression of percent trap catch vs. number of days deployed yielded a quadratic expression that predicts 50% loss of lure attractiveness at 50 d after lure deployment and 90% loss at 137 d. The data transformed for lure degradation revealed 4 apparent population density peaks including 2 minor peaks with highest mean trap catch in early Apr and late Oct, and 2 major peaks with highest mean trap catch on 31 May and 1 Aug. A very small number of moths were collected on control traps without a lure. However, the pattern of trap catch on unbaited sticky cards closely paralleled that of the pheromone-baited traps.
