TY - JOUR T1 - Transgenic Tomato Plants with a Modified Ability to Synthesize Indole-3-acetyl- beta -1-O-D -glucose AN - 907175973; 15570395 AB - Esterification of indole-3-acetic acid (IAA) is thought to be an important component in the homeostatic regulation of the levels of this phytohormone. To better understand the role of the initial step in IAA esterification in the control of IAA levels, transgenic tomato plants were generated that either express maize IAGLU or have reduced levels of the enzyme IAA-glucose synthetase. These plants were obtained by expressing maize IAGLU in either sense or antisense orientation using the CaMV35S promoter. The maize IAGLU probe hybridized to two transcripts (1.3 kb and 2.5 kb) in wild-type tomato vegetative tissue and green fruit. The sense and antisense transformants exhibited distinct phenotypic characteristics. Sense transformants showed an almost complete lack of root initiation and development. Antisense transgenic plants, on the other hand, had unusually well developed root systems at early stages in development, and the amount of the endogenous 75 kDa IAGLU protein was reduced. IAGLU antisense plants also had reduced levels of IAA-glucose and lower esterified IAA.

Currently established biological control agents attack only the capitula (flowerheads), and are not effectively controlling the plant in much of its range. The geographic center of diversity for the plant appears to be in Turkey, but no agents have been introduced from this country. Ceratapion basicorne (Coleoptera: Apionidae) is common in Central Turkey, attacking 25-100% of yellow starthistle plants. In a field experiment, Ceratapion spp. attacked 90% of yellow starthistle plants and 88% of milk thistle plants (Silybum marianum) but not seven other plant species, including artichoke and safflower. We suspect that a different species of insect attacked milk thistle, but they emerged before the plants were sampled. Laboratory tests showed that C. basicorne does not oviposit in milk thistle. Ceratapion basicorne appears to be more host specific than was suggested by previous studies of a population in Italy (Clement etal. 1989. Ann. Entomol. Soc. Am. 82: 741-747). The insect is gregarious, and the number of larvae per plant was positively correlated to root diameter. The level of damage to individual plants was positively correlated to the proportion of plants attacked, indicating aggregation both among plants and within plants. Field data did not show any impact of the insect on plant size or number of capitula, but germination rate of seeds produced by infested plants was 15% lower than for uninfested plants at two of three sites studied.

In field plots, plants were infested with waterhyacinth weevils (Neoechetina bruchi and N. eichhorniae) and leaves were scarred by weevil feeding. Subsequent infection by the fungal pathogen Cercospora piaropi caused necrotic lesions to form on leaves. Necrosis development was 7.5- and 10.5-fold greater in plots augmented with both weevils and C. piaropi and weevils alone, respectively, than in plots receiving only C. piaropi. Twenty-four days after weevil infestation, the percentage of laminar area covered by lesions on third-youngest and oldest live leaves was elevated 2.3-2.5-fold in plots augmented with weevils. Scar density and necrosis coverage on young leaf laminae were positively correlated, even though antipathogenic soluble peroxidases were elevated 3-fold in plots augmented with weevils alone or weevils and C. piaropi. Combined weevil and fungal augmentation decreased shoot densities and leaves per plant. In a no-choice bioassay, weevil feeding on oldest but not young leaves was reduced 44 two weeks after C. piaropi inoculation. Protein content and peroxidase activities were elevated 2-6-fold in oldest leaves three weeks after inoculation. Augmentation with both waterhyacinth weevils and C. piaropi led to the development of an additive biological control impact, mediated by one or more direct interactions between these agents, and not plant quality effects.

A list of genes expressed by intestinal IELs of Eimeria-infected chickens was compiled using the expressed sequence tag (EST) strategy. The 14,409 ESTs consisted of 1851 clusters and 7595 singletons, which revealed 9446 unique genes in the data set. Comparison of the sequence data with chicken DNA sequences in GenBank identified 125 novel clones. This EST library will provide a valuable resource for profiling global gene expression in normal and pathogen-infected chickens and identifying additional unique immune-related genes.

AN - 68516678; 16121232 AB - Escherichia coli serogroup O103 has been associated with gastrointestinal illness and hemolytic uremic syndrome. To develop PCR-based methods for detection and identification of this serogroup, the DNA sequence of the 12,033-bp region containing the O antigen gene cluster of Escherichia coli O103 was determined. Of the 12 open reading frames identified, the E. coli O103 wzx (O antigen flippase) and wzy (O antigen polymerase) genes were selected as targets for development of both conventional and real-time PCR assays specific for this serogroup. In addition, a multiplex PCR targeting the Shiga toxin (Stx) 1 (stx1), Shiga toxin 2 (stx2), wzx, and wzy genes was developed to differentiate Stx-producing E. coli O103 from non-toxigenic strains. The PCR assays can be employed to identify E. coli serogroup O103, replacing antigen-based serotyping, and to potentially detect the organism in food, fecal, or environmental samples.

AN - 68510485; 16117137 AB - Three probabilistic models were developed for characterizing the risk of mortality and subacute coagulopathy to Poouli, an endangered nontarget avian species, in broadcast diphacinone-baited areas on Hawaii, USA. For single-day exposure, the risk of Poouli mortality approaches 0. For 5-d exposure, the mean probability of mortality increased to 3% for adult and 8% for juvenile Poouli populations. For Poouli that consume snails containing diphacinone residues for 14 d, the model predicted increased levels of coagulopathy for 0.42 and 11% of adult and juvenile Poouli populations, respectively. Worst-case deterministic risk characterizations predicted acceptable levels of risk for nonthreatened or endangered species such as northern bobwhite quail and mallards. Also, no acute toxicity was noted for snails and slugs that feed on diphacinone baits.

AN - 68038688; 16022308 AB - The effects of planting dates 2-3-wk apart on boll weevil, Anthonomus grandis grandis Boheman (Coleoptera: Curculionidae), field-level populations, and feeding and oviposition damage to cotton, Gossypium hirsutum L., squares and bolls, were studied during 2002 and 2003 in the Lower Rio Grande Valley of Texas. Squares were 44-56% more abundant in some later planted treatments than in the earlier planted treatments, but mean cumulative numbers of oviposition- and feeding-damaged squares were 2.7 - 4.8-fold greater in some later planted treatments than in earlier treatments. Increased square production in later planted cotton was offset by boll weevil infestations that occurred when squares are most vulnerable and contribute most toward the pest's reproduction. Early planting avoided boll weevil population buildups in the field when large squares were abundant. Lint yields in 2002 did not differ significantly between the planting date treatments, but in 2003, mean yield in the middle treatment was 23% greater than in the early and late-planted treatments. Insecticide sprays in the earliest planted treatment of each year, based on the 10% damaged squares threshold, were >33% and >43% fewer than in the corresponding middle and latest planting treatments, respectively.

AN - 68020357; 16007955 AB - The insect repellent DEET (0.1% concentration), used as a mosquito oviposition deterrent in the laboratory, influenced the retention and maintenance of mature eggs by caged gravid female Aedes albopictus Skuse. This egg-retention mechanism could benefit survival because the gravid females were ultimately able to lay maintained eggs upon availability of water, but the length of forced egg-retention time reduced the number of eggs laid per female. Gravid females with retained eggs also laid a higher percentage of eggs that failed to tan, and this percentage increased with time duration of egg-retention. Percent egg hatch was not significantly affected by DEET when used as an oviposition deterrent; however, percent hatch was affected by time duration of egg-retention in both treated (exposed to DEET) and untreated (control) gravid females. The rate of egg hatch was considerably reduced after three weeks of retention; this reduction declined to zero for treated and control females at six and four weeks post-treatment, respectively. The fecundity and fertility of gravid female Ae. albopictus were affected by the time duration of forced egg-retention.

AN - 68019833; 16008221 AB - To determine effects of repeated aerosol exposures to fly ash dust on respiratory tracts of tent-confined goats. 12 weanling Boer-Spanish crossbred goats. Goats were randomly assigned to 2 groups: fly ash treatment group (principal goats, n = 6) or control group (control goats, 6). Aerosolized fly ash dust was provided during a 4-hour period for each of 6 applications given over 3 months and one 2-hour application prior to necropsy. Fly ash particle diameters ranged from 0.1 to 130 microm and averaged 17.8 microm, with 1.5% of fly ash particles in the 0.1- to 5-microm-diameter range. A mean +/- SD of 748 +/- 152 g/treatment was delivered inside a tent containing principal goats; control goats were placed inside a similar tent for 4-hour treatments without dust. Following treatment, rectal temperatures were taken at 0, 4, 6, 8, 24, and 72 hours; Hcts were recorded at 0, 24, and 72 hours. Rectal temperatures were significantly increased at 4, 6, and 8 hours and decreased at 72 hours, compared with 0 hours. Mean +/- SEM Hct values were significantly increased for principal goats (3747 +/- 0.39%), compared with control goats (36.17 +/- 0.42%). A significant increase in the mean area of gross atelectatic lung lesions (1,410 mm2) was found in principal goats (n = 6), compared with control goats (440 mm2; 5). An increase in atelectatic lung lesions was observed in principal goats, compared with control goats; however, overall, fly ash dust effects were nontoxic.

AN - 67953203; 15614562 AB - Saccharomyces cerevisiae served as a model fungal system to examine functional genomics of oxidative stress responses and reactions to test antioxidant compounds. Twenty-two strains of S. cerevisiae, including a broad spectrum of singular gene deletion mutants, were exposed to hydrogen peroxide (H2O2) to examine phenotypic response to oxidative stress. Responses of particular mutants treated with gallic, tannic or caffeic acids, or methyl gallate, during H2O2 exposure, indicated that these compounds alleviated oxidative stress. These compounds are also potent inhibitors of aflatoxin biosynthesis in Aspergillus flavus. To gain further insights into a potential link between oxidative stress and aflatoxin biosynthesis, 43 orthologs of S. cerevisiae genes involved in gene regulation, signal transduction (e.g., SHO1, HOG1, etc.) and antioxidation (e.g., CTT1, CTA1, etc.) were identified in an A. flavus expressed sequence tag library. A successful exemplary functional complementation of an antioxidative stress gene from A. flavus, mitochondrial superoxide dismutase (sodA), in a sod2Delta yeast mutant further supported the potential of S. cerevisiae deletion mutants to serve as a model system to study A. flavus. Use of this system to further examine functional genomics of oxidative stress in aflatoxigenesis and reduction of aflatoxin biosynthesis by antioxidants is discussed.

AN - 67930058; 15954710 AB - There is a large and rapidly growing market for fresh-cut fruit. Microbial volatile organic compounds indicate the presence of fungal or bacterial contamination in fruit. In order to determine whether microbial volatile organic compounds can be used to detect contamination before fruit becomes unmarketable, pieces of cantaloupe, apple, pineapple, and orange were inoculated with a variety of fungal species, incubated at 25 degrees C, then sealed in glass vials. The volatiles were extracted by headspace solid-phase microextraction and analyzed by gas chromatography-mass spectrometry. Forty-five compounds were identified that might serve as unique identifiers of fungal contamination. Fungal contamination can be detected as early as 24 h after inoculation.

AN - 67873486; 15917080 AB - Selenium is an essential trace element for humans and other animals, and there is mounting evidence for the efficacy of certain forms of selenium as cancer-chemopreventive compounds. However, over the years, numerous elements such as As, Cu, Zn, Cd, Hg, Sn, Pb, Ni, Co, Sb, Bi, Ag, Au, and Mo have been found to inhibit anti-carcinogenic effects of selenium, which may affect the anti-carcinogenic activity of selenium. The interaction between selenium and arsenic has been one of the most extensively studied. The proposed mechanisms of this interaction include the increase of biliary excretion and direct interaction/precipitation of selenium and arsenic, and their effects on zinc finger protein function, cellular signaling and methylation pathways. This article focuses on these proposed mechanisms and how anti-carcinogenic effects of selenium may be affected by arsenic.

AN - 67841521; 15712368 AB - The integrated control concept emphasizes the importance of both chemical and biological control for pest suppression in agricultural systems. A two-year field study was conducted to evaluate the selectivity of acetamiprid for the control of Bemisia tabaci (Gennadius) in cotton compared with a proven selective regime based on the insect growth regulators (IGRs) pyriproxyfen and buprofezin. Acetamiprid was highly effective in controlling all stages of B tabaci compared with an untreated control, and generally produced lower pest densities than the IGR regime. Univariate analyses indicated that nine of 17 taxa of arthropod predators were significantly depressed with the use of acetamiprid compared with an untreated control, including common species such as Geocoris punctipes (Say), Orius tristicolor (White), Chrysoperla carnea Stephens sensu lato, Collops vittatus (Say), Hippodamia convergens Guérin-Méneville, and Drapetis nr divergens. Compared with results from independent, concurrent studies using mixtures of broad-spectrum insecticides at the same research site, acetamiprid depressed populations of fewer predator taxa; but, for eight predator taxa significantly affected by both regimes, the average population reduction was roughly equal. In contrast, only four taxa were significantly reduced in the IGR regime compared with the untreated control and three of these were omnivores that function primarily as plant pests. Principal response curves analyses (a time-dependent, multivariate ordination method) confirmed these patterns of population change for the entire predator community. Predator:prey ratios generally increased with the use of both IGRs and acetamiprid compared with an untreated control, but ratios were consistently higher with IGRs. Parasitism by aphelinid parasitoids was unaffected or depressed slightly in all insecticide regimes compared with the control. Because of its high efficacy, acetamiprid may play an important role in later stages of B tabaci control where less emphasis is placed on selectivity. However, our results suggest that acetamiprid would be a poor substitute for the currently used IGRs in the initial stage of control where insecticide selectivity is crucial to a functional integrated control program for B tabaci in cotton.

AN - 67832277; 15661839 AB - A subpopulation of calves, herein termed "hyperresponders" (HPR), was identified and defined by the patterns of plasma TNF-alpha concentrations that developed following two challenges with endotoxin (LPS, 0.8 mug Escherichia coli 055:B5 LPS/kg(0.75) live body wt) separated by 5 days. The principle characteristic of HPR calves was a failure to develop tolerance to repeated LPS challenge that was evident in the magnitude of the TNF-alpha concentrations and prolonged severity of pathological sequellae. Whereas calves failing to develop LPS tolerance were identified on the basis of their excessive in vivo plasma TNF-alpha concentration responses, in vitro TNF-alpha responses of peripheral blood mononuclear cells isolated from each calf and challenged with LPS or PMA did not correlate or predict the magnitude of in vivo plasma TNF response of the calf. Intentional breeding to obtain calves from bulls and/or cows documented as HPR resulted in offspring displaying the HPR character when similar progeny calves were tested with LPS in vivo, with extensive controls in place to account for sources of variability in the general TNF-alpha response to LPS that might compromise interpretation of the data. Feed intake, clinical serology and hematology profiles, and acute-phase protein responses of HPR calves following LPS were significantly different from those of calves displaying tolerance. These results suggest that the pattern of plasma TNF-alpha changes that evolve from a low-level double LPS challenge effectively reveal the presence of a genetic potential for animals to display excessive or prolonged pathological response to LPS-related stress and compromised prognosis for recovery.

The expression levels of Zymopdc gene in the host, as measured by a colorimetric assay based on PDC catalyzed formation of (R)-phenylacetylcarbinol ((R)-PAC), appeared to be dependent on the strength of corresponding Gram-positive promoters. A constitutive, highly expressed promoter conferred the greatest PDC activity, and an acid-inducible promoter demonstrated acid-inducible expression. The metabolic production of ethanol and other products was examined in flask fermentations. More than eightfold increases in acetaldehyde concentrations were detected in two recombinant strains. However, no detectable differences for ethanol fermentation in these engineered strains were observed compared with that of the strain carrying lacZ reporter.

Within a 48-ha stem-mapped sample area, after a mechanical thinning, all stumps were examined for fire scars and 526 stumps were cut to ground level and aged. Before 1865, which was the last widespread fire event, the mean interval between scars for an individual tree was 17.3 years and the mean fire return interval for the period with the greatest number of recording trees was 11.4 years. A significantly greater than expected number of fires occurred in dry La Nina years, but these fires were not significantly larger in size than fires in other years. The response of mixed-conifer recruitment to climate and fire events varied by species. Before 1865, Jeffrey pine and sugar pine recruitment were correlated with wet El Nino years, but only sugar pine establishment was associated with fire. Red fir recruitment did not follow fire events but was associated with El Nino years before and after 1865. Most white fir and incense cedar (84% ), including many large-diameter trees (> 76 cm dbh), recruited after the last widespread fire in 1865. Although tree distribution is clustered in the southern Sierra Nevada, mixed-conifer groups are not age cohorts because species have different recruitment patterns relative to climate and fire events. In mixed conifer, top-down effects of fire and weather on recruitment are mediated by different species responses to these effects and within-stand differences in where species are located. FOR.

We used molecular methods (DNA sequence analysis of the internally transcribed spacer [ITS] region of rDNA) to compare three viewpoints: ECM fungi on the roots in a southern Sierra Nevada Abies-dominated old-growth forest, fungi in scat samples collected from small mammals in the same forest, and hypogeous sporocarps found throughout the Sierra Nevada. We found that hypogeous taxa accounted for a minimum of 21% of the species and 25- 40% of the dry root biomass of all samples. This estimate is two to three times greater than estimates from previous studies. This difference may be due to methodological advantages of this study, but may also be related to conditions in dry forests typical of western North America where prolonged drought may favor this form of fruiting. Although molecular analysis of scat samples did not add to our view of the ECM roots, we readily isolated sequences from Rhizopogon species. From these results we inferred that two species, R. occidentalis and R. olivaceotinctus, are represented primarily in the spore bank and may be dependent on substantial disturbance to become abundant on roots.

We conducted studies in a mixed-conifer forest in the Sierra Nevada, California, to determine relationships between established understory trees and microsite quality, and to examine the effect of fire intensity and shrub cover on seedling establishment. Most of the conifer species were found on microsites with relatively high soil moisture and relatively low direct solar radiation. All species had greater frequency under shadier conditions except for Jeffrey pine, which was found on drier, more open microsites. Although seedlings were more abundant on mineral soil than expected, intact litter and forest floor was not a barrier to establishment. Mortality of planted seedlings was high, particularly in exposed areas. Although shrub cover may initially aid survival, few conifer saplings were present in shrub-dominated patches, possibly because shrubs can be aggressive competitors for soil moisture. The lack of regeneration, logs, or snags in many openings suggest that large gaps are hostile environments for tree seedlings. Results suggest that reductions in shrub cover may benefit tree establishment, but increasing understory light and decreasing surface soil moisture through canopy cover reductions may not. FOR.

ER - TY - JOUR T1 - Dose-Response of Codling Moth (Lepidoptera: Tortricidae) to Ethyl (E, Z)-2,4-Decadienoate in Apple Orchards Treated with Sex Pheromone Dispensers AN - 20197849; 6256528 AB - Studies were conducted in apple, Malus domestica Borkhausen, orchards to evaluate the attractiveness of the kairomone, ethyl (E, Z)-2,4-decadienoate (pear ester), loaded at various rates into gray halobutyl septa, to adult codling moth, Cydia pomonella L. All studies were conducted in orchards treated with sex pheromone mating disruption. Lure loadings from 0.01 mu g to 50.0 mg were evaluated in 12 orchard plots in 1999. Lures loaded with 1.0-50.0 and 0.1-50.0 mg caught significantly more male and female moths than the blank control, respectively. Field dose-response studies were repeated with five lure rates (0.1-40.0 mg) of pear ester during four periods during the 2000 season. Significant seasonal date and rate effects were found for the capture of males and female moths. The 0.1-mg lure caught significantly fewer males than the 1.0-, 3.0-, and 40.0-mg lures. The 40.0-mg lure caught significantly fewer female moths than the 1.0- and 3.0-mg lures. The 3.0-mg lure caught a higher proportion of virgin females than the 10.0- and 40.0-mg lures. The attractiveness of the 1.0 and 3.0 mg pear ester loadings were compared with a sex pheromone lure during a 10-wk trial in 2002. Both pear ester lures caught significantly fewer moths than the sex pheromone lure during the first 4 wk of the study and over the entire 10-wk period. However, no difference among lures occurred during week 5, and the 3.0-mg lure caught significantly more moths than the sex pheromone lure during week 6. The 3.0-mg lure caught a significantly higher proportion of female moths and a higher proportion of virgin female moths than the 1.0-mg lure. These studies suggest that the optimal loading of pear ester for capture of codling moth in mating disrupted apple orchards likely depends on the specific objectives of the monitoring program.

The herbicide was used to kill broadleaf weeds in the marginal areas that served as hosts for tarnished plant bugs, Lygus lineolaris (Palisot de Beauvois). The herbicide treatment caused a significant reduction in wild host densities in the treated test sites in all 3 yr. Tarnished plant bug populations in treated test sites did not increase significantly in the treated marginal areas during April and May after treatment of the margins in the first 2 wk of March in 2000 and 2001. The herbicide application was made in the first 2 wk of April 1999, and plant bug populations increased in treated marginal areas in this year. The increase was thought to be caused by plant bugs moving to Italian ryegrass, Lolium multiflorum Lamarck, a previously unreported plant bug host, which was not affected by the herbicide. Laboratory tests showed that plant bugs would oviposit in flowering or nonflowering ryegrass when caged on ryegrass for a 6-d period. Newly emerged nymphs developed into adults (56%) when reared on floral spikelets of ryegrass, but no adults were obtained when they were reared on ryegrass stems and leaves. Rearing on floral spikelets beginning with third-instar nymphs resulted in 92% adults, whereas third-instar nymphs reared on stems and leaves produced no adults. These results showed that ryegrass could serve as a reproductive host for plant bugs when it flowered during late April and May. Application of the herbicide in March, when ryegrass was not in flower, resulted in no significant increases in plant bug populations on wild hosts (mainly ryegrass) during April and May in 2 yr of the field study.

Roem. and Schult.], established in bands parallel to corn rows, on western corn rootworm (Diabrotica virgifera virgifera LeConte) survival, corn root injury, lodging, biomass production, and yield. Results suggested that the presence of foxtail as an alternate host influenced the degree and progression of corn rootworm damage and adult emergence in a given locality. Rootworm adults emerged later from foxtail band areas and had smaller head capsule size than did individuals from areas without foxtail, consistent with earlier findings that foxtail in the diet of western corn rootworm was a poor nutritional substitute for corn. Lodging was reduced in the presence of yellow foxtail in some cases, but corn stover biomass and yield also were lower. Influences, if any, of soil type on rootworm survival were unclear because of differences in planting date between the two sites. Foxtail may function as a buffer to reduce rootworm damage to corn and serves as an alternate host that should be considered in the development of resistance management strategies for transgenic corn modified for rootworm resistance.

Studies were conducted in apple orchards, Malus domestica Borkhausen, treated with or without sex pheromone dispensers for mating disruption (MD). Septa were loaded with either one or both compounds at rates of 0.0, 0.3, and 3.0 mg pear ester and 0.0 and 3.0 mg codlemone in the first series of tests. Traps baited with a 3.0/3.0-mg blend caught significantly more males and total number of codling moths than traps baited with either compound alone in both types of orchards. Traps baited with two lures loaded individually with pear ester (3.0 mg) and codlemone (3.0 mg) caught significantly fewer males and total moths than traps baited with the dual lure (3.0/3.0 mg). The addition of 3.0 mg codlemone to pear ester did not significantly affect the capture of female moths. However, increasing the loading of pear ester from 0.3 to 3.0 mg in the dual lure significantly increased female moth catch in the untreated orchard but not in the sex pheromone MD orchard. Increasing the loading of pear ester to 20.0 mg in a dual lure with 3.0 mg codlemone significantly increased total codling moth catch compared with a 3.0 mg codlemone lure, but female catch was significantly lower compared with traps baited with a 3.0 mg pear ester lure. Adding a 3.0 mg pear ester lure to traps baited with a 42.0 mg sex pheromone lure significantly reduced male moth catch compared with the sex pheromone lure alone but did not reduce the catch of female moths compared with traps baited with a 3.0 mg pear ester lure alone.

Soil and forest floor layers were sampled separately on eight paired sites. Within the forest floor oribatid, mesostigmatid, and to a marginal extent, prostigmatid mites, were reduced in thinned stands compared with unthinned stands. No differences were found for Collembola in the forest floor or for any mite suborder within the soil. Family level examination of mesostigmatid and prostigmatid mites revealed significant differences between stand types for both horizons. At the species level, thinning influenced numerous oribatid mites and Collembola. For oribatid mites, significant or marginally significant differences were found for seven of 15 common species in the forest floor and five of 16 common species in soil. Collembola were affected less, with differences found for one of 11 common species in the forest floor and three of 13 common species in soil. Multivariate analysis of variance and ordination indicated that forest thinning had little influence on the composition of oribatid mite and collembolan communities within either the forest floor or soil. Differences in microclimate or in the accumulation of organic matter on the forest floor were likely most responsible for the observed patterns of abundance. Considering the role that microarthropods play in nutrient cycling, determining the functional response of a wide range of taxa to thinning may be important to effective ecosystem management.

Three consecutive simulated rainfall events, producing 35 mm rainfall and separated by 24 h, were carried out for each plot. Fecal indicator (Escherichia coli, enterococci, Clostridium perfringens and coliphage) loads released in rainfall runoff from plots treated with fresh cattle manure, aged cattle manure and swine slurry treatments ranged from 5.52 x 10 super(5) to 4.36 x 10 super(9), 3.92 x 10 super(4) to 4.86 x 10 super(8), and 9.63 x 10 super(5) to 3.05 x 10 super(8), respectively. Plot runoff concentrations of protozoa (Cryptosporidium oocysts and Giardia cysts) ranged from 1.65 x 10 super(5) to 1.04 x 10 super(6), 2.93 x 10 super(3) to 2.75 x 10 super(5), and 9.12 x 10 super(4) to 3.58 x 10 super(6) for fresh cattle manure, aged cattle manure and swine slurry plot treatments, respectively. These results suggest that large microbial loads could be released via heavy precipitation events that produce runoff from livestock manure-applied agricultural fields, of even modest size, and could have a significant impact on water bodies within the watershed. Because of the lack of multiplication in the environment, highly elevated concentrations in manured land runoff, and correlation to protozoan parasite presence, Clostridium may be an alternative indicator for livestock manure contamination.

The disease outbreak is limited to a four county area in southern Pennsylvania. Using sequencing and phylogenetic analyses, we have determined that the Pennsylvania isolates divide into two clades, suggesting the possibility of multiple introductions. The two clades have somewhat distinct biological properties, further supporting the phylogenetic divisions. To provide context for the overall Pennsylvania population diversity, several isolates from a single orchard were sequenced. In contrast to the populations taken from around the quarantine zone, the isolates from single orchards were remarkably identical. PPV diversity levels also were determined for replicating populations within individual hosts. Like most RNA viruses, PPV generates high levels of genetic diversity within its replicating populations, with mutation frequencies ranging from 0.8 to 1.3 mutations/1000 bases. However, very little of this diversity is observed in the consensus sequences of isolates found within close proximity in a single orchard, suggesting that most of the population diversity observed at the level of replicating populations has little effect in the natural evolutionary processes of PPV.

T. gondii was identified in a Hawaiian monk seal (Monachus schauinslandi) that had visceral and cerebral lesions. Tachyzoites were found in the lymph nodes, spleen, diaphragm, heart, adrenal glands, and brain. A few tissue cysts were found in sections of the cerebrum. The diagnosis was confirmed serologically, by immunohistochemical staining with T. gondii-specific polyclonal rabbit serum, and by the detection of T. gondii DNA. The genotype was determined to be type III by restriction fragment length polymorphisms of the SAG2 gene. This is the first report of T. gondii infection in a Hawaiian monk seal.

Loblolly pine stands in 3 southern states (with a predominance of sites in central and southern Alabama) are reported to be declining based on data from Forest Health Monitoring plots established in the 1990's. Current studies of affected stands show a strong correlation with (upland) site, deterioration of fine roots, presence of a fairly constant set of insect associates, and infection by Leptographium spp. affecting the primary roots. The influence of fire, previous agriculture, and landform are other factors that may have a role in the loblolly decline complex. The symptoms of the decline are sparse crowns, short chlorotic needles, and reduced radial growth primarily above 40 years of age and first apparent in trees in the 40-50 year age class. Mortality can occur beginning as little as two to three years after first symptom expression. Although the symptoms of the decline complex are similar to those of littleleaf disease, the site conditions on stands are found expressing this decline are different. On upland sites on federal lands, loblolly pine is the major forest type since it was used for watershed restoration and is easily regenerated. Many of these sites are now managed for red-cockaded woodpecker (RCW) habitat and decline of the pine stands is impacting the long-term habitat needs of this endangered species. One of mitigations recommended for decline sites is to convert them to longleaf pine where site conditions are suitable to fulfill the habitat requirements for RCW. Additional monitoring plots are being installed on National Forest upland sites in Texas, Louisiana, Arkansas, and Mississippi. This monitoring process will help define the range and impact of loblolly pine decline and will further assess Leptographium spp. component of the pine decline complex.

Enterotoxigenic strains of E. coli affecting nursery-age pigs have become more difficult to treat because of increased antibiotic resistance, and alternatives to antibiotics are currently being sought. Our laboratory developed a defined culture of commensal bacteria of porcine gastrointestinal tract origin, maintained it in continuous-flow culture for 3 yr, and designated it as RPCF. Laboratory studies have shown that RPCF-treated pigs had decreased mortality and bacterial shedding compared with controls when challenged with enterotoxigenic strains of E. coli. The objective of the present study was to evaluate the practicality, safety, and efficacy of RPCF to protect nursery-age pigs in commercial swine operations from field challenge by enterotoxigenic strains of E. coli. In field studies involving six geographically separated farms with a history of high mortality from K-88 and F-18 strains of E. coli, piglets were administered RPCF within 24 h of birth and monitored throughout the nursery period. A total of 21,467 piglets were treated with RPCF, and a similar number of piglets on the same farms served as untreated controls. On five of six farms, mortality in RPCF-treated pigs decreased by an average of 2.6% compared with untreated pigs. Differences in mortality were not observed in RPCF-treated pigs compared with controls on one Minnesota farm. When projected to an annual basis, the economic benefits from decreased medication costs and mortality averaged $24,663 per farm. These studies suggest that under commercial conditions, RPCF tended to control disease induced by enterotoxigenic E. coli, and that RPCF may be a viable alternative to the use of antibiotics.

We measured bone mineralization and calcium metabolic parameters longitudinally in a group of 99 adolescents. We found a significant relationship between calcium absorption and skeletal calcium accretion and the Fok1, but not other VDR or related, genetic polymorphisms. It seems that the Fok1 polymorphism directly affects bone mineralization during pubertal growth through an effect on calcium absorption. Introduction: There are few data regarding the relationship between genetic markers for low bone mass and changes in calcium metabolism in childhood or adolescence. We sought to identify the effects of polymorphisms of the vitamin D receptor (VDR) on calcium and bone mineral metabolism in a longitudinal study of pubertal adolescents. Materials and Methods: Adolescents (n = 99) received comprehensive stable isotope studies of calcium absorption, bone calcium kinetics, and bone mineralization. Studies were repeated 12 months later. Polymorphisms of putative genetic markers were determined and related to bone mineralization and calcium metabolic finding. Results were analyzed by ANOVA in which changes over time were determined using the initial value as a covariate. Results: Polymorphisms of the Fok1 gene of the VDR were significantly related to calcium absorption (p = 0.008) and whole body BMC (p = 0.03) and BMD (p = 0.006). The Fok1 effect on whole body BMD was significant for those with Ca intake >800 mg/day (p < 0.001), whereas for those with Ca intake less than or equal to 800 mg/day, the Fok1 genotype did not have a significant effect on whole body BMD (p = 0.40). The Fok1 genotype was significantly related to the changes during the year in whole body calcium accretion, with the ff genotype having a 63 plus or minus 20 mg/day deficit compared with the FF genotype (p = 0.008). Conclusions: The Fok1 polymorphism of the VDR receptor seems to directly affect bone mineral accretion during pubertal growth through an effect on calcium absorption. The relationship between different genetic polymorphisms and bone mineral metabolism may vary by life stage as well as diet.

After three generations of sib-sib mating, individuals from three lines of mice were either subject to further inbreeding or were mated with an outbred individual. Subsequently, these mice, plus a control line, which were first generation (F sub(1)) mice from unrelated individuals kept in captivity for the same duration as the treatment lines, were released into isolated pens in a forest in western Montana. Survival of individual mice was recorded. Survival models that allowed variation in breeding treatments were well supported, whereas models explaining variation in line, or release location were not well supported. Survival was highest for offspring of the outcross group, intermediate for the inbred animals, and lowest for the control group. This suggests that the introduction of migrants can reduce inbreeding depression, as theory predicts. We also show limited evidence for purging of deleterious recessive alleles that can cause inbreeding depression. While purging may have occurred, the demographic cost was non-trivial as 5 of 8 of our inbred mouse lines went extinct during the inbreeding process.

Biofilms on inert surfaces have been studied in depth using confocal scanning laser microscopy (CSLM) with a variety of fluorescent probes. In contrast, there have been few studies of native microbial aggregates or biofilms on living surfaces, including plants. In this study we used CSLM in combination with the LIVE/DEAD super(()R) BacLight(TM) Viability Kit (Molecular Probes Inc.) to determine the thickness of native microbial aggregates on alfalfa, clover and mung bean sprouts purchased from retail outlets. A survey of aggregate thickness was made by use of a 20x dry lens primarily due to its large free working distance, broad field of view and the uneven topography and shape of cotyledon surfaces. Values for measured thickness (z-axis) were corrected based on the point spread function of fluorescent latex spheres (1.98 mu m in diameter). Aggregates consisted primarily of live bacteria. Aggregates on mung bean cotyledons were significantly (P0.05) different for aggregates on clover and alfalfa. Bacteria in fully hydrated aggregates as imaged by CSLM appeared to be less densely packed when compared to sprout surface biofilms imaged previously in our laboratory with conventional scanning electron microscopy techniques, most likely due to the presence of hydrated bacterial exopolymers. Despite a lack of considerable thickness, aggregates and biofilms on plant surfaces may harbor plant and human pathogens making their eradication more problematic and also protect pathogens and native bacteria from adverse environmental conditions.

Heat resistance kinetics for 5 serotypes of E. coli at 60 degree C were estimated in beef gravy using a submerged coil heating apparatus. The observed survival curves were sigmoidal and there were significant differences (p=0.05) of the survival curves among the serotypes. Consequently, a model was developed that accounted for the sigmoidal shape of the survival curves and the serotype effects. Specifically, variance components for serotypes and replicates within serotypes were estimated using mixed effect nonlinear modeling. If it is assumed that the studied serotypes represent a random sample from a population of E. coli strains or serotypes, then, from the derived estimates, probability intervals of the expected lethality for random selected serotypes can be computed. For example, expected serotype-specific lethalities at 60 degree C for 10 min are estimated to range between 5 and 9 log sub(10) with 95% probability. On the other hand, to obtain a 6-log sub(10) lethality, the expected minutes range, with 95% probability, from 6 to 12 min. The results from this study show that serotypes of E. coli display a wide range of heat resistance with nonlinear survival curves.

This study compares morphological characteristics (dimensions and cell wall structure), chemical properties of cell wall surfaces (charge, hydrophobicity, and lectin binding), and performance (germination rate and drying stability) among these three spore types. Submerged conidia and aerial conidia both possessed thick, double-layered cell walls, with hydrophobic regions on their surfaces. However, in contrast to aerial conidia, submerged conidia have: (1) a greater affinity for the lectin concanavalin-A; (2) more anionic net surface charge; and (3) a less distinct outer rodlet layer. Blastospores were longer and more variable in length than both submerged conidia and aerial conidia, and had thinner single-layered cell walls that lacked an outer rodlet layer. Also, blastospores had a greater affinity than either conidia type for the lectin, wheat germ agglutinin. Blastaspores lacked hydrophobic regions on their surface, and had a lower anionic net surface charge than submerged conidia. In culture, blastospores germinated the fastest followed by submerged conidia, and then aerial conidia. Survival of submerged conidia and aerial conidia were similar after drying on silica gel, and was greater than that for blastospores. We provide corroborating information for differentiating spore types previously based on method of production, sporogenesis, and appearance of spores. These physical characteristics may have practical application for predicting spore-performance characteristics relevant to production and efficacy of mycoinsecticides.

Improved TB tests are desperately needed, as many reindeer are falsely classified as reactors by current testing procedures. Sera collected sequentially from 11 (experimentally) Mycobacterium bovis-infected reindeer and 4 noninfected reindeer were evaluated by enzyme-linked immunosorbent assay (ELISA), immunoblotting, and multiantigen print immunoassay (MAPIA) for antibody specific to M. bovis antigens. Specific antibody was detected as early as 4 weeks after challenge with M. bovis. By MAPIA, sera were tested with 12 native and recombinant antigens, which were used to coat nitrocellulose. All M. bovis-infected reindeer developed responses to MPB83 and a fusion protein, Acr1/MPB83, and 9/11 had responses to MPB70. Other antigens less commonly recognized included MPB59, ESAT-6, and CFP10. Administration of purified protein derivatives for skin testing boosted serum antibody responses, as detected by each of the assays. Of the noninfected reindeer, 2/4 had responses that were detectable immediately following skin testing, which correlated with pathological findings (i.e., presence of granulomatous lesions yet the absence of acid-fast bacteria). The levels of specific antibody produced by infected reindeer appeared to be associated with disease progression but not with cell-mediated immunity. These findings indicate that M. bovis infection of reindeer elicits an antibody response to multiple antigens that can be boosted by skin testing. Serological tests using carefully selected specific antigens have potential for early detection of infections in reindeer.

Spore production was increased by the addition of up to 150 g l super(-1) polyethylene glycol 200 (PEG). Spores from high osmolality medium (HOM spores) containing 100 g l super(-1) PEG had thin cell walls and dimensions more similar to blastospores than submerged conidia or aerial conidia. However, a faint electron-dense layer separating primary and secondary HOM spores' cell walls was discernable by transmission electron microscopy as found in aerial and submerged conidia but not found in blastospores. HOM spores also appeared to have an outer rodlet layer, unlike blastospores, although it was thinner than those observed in submerged conidia. HOM spores' surfaces possessed hydrophobic microsites, which was further evidence of the presence of a rodlet layer. In addition, HOM spores had concentrations of exposed N-acetyl- beta -d-glucosaminyl residues intermediate between blastospores and submerged conidia potentially indicating a masking of underlying cell wall by a rodlet layer. All spore types had exposed alpha -d-mannosyl and/or alpha -d-glucosyl residues, but lacked oligosaccharides. Similar to blastospores, HOM spores were less anionic than submerged conida. Although HOM spores had thin cell walls, they were more stable to drying than blastospores and submerged conidia. Relative drying stability did not appear to be the result of differences in polyol or trehalose concentrations, since trehalose concentrations were lower in HOM spores than submerged conidia and polyol concentrations were similar between the two spore types. HOM spores had faster germination rates than submerged conidia, similar to blastospores, and they were more pathogenic to Schistocerca americana than submerged conidia and aerial conidia.

The virulence mechanisms of R. salmoninarum are not well understood. Production of a 57-kDa protein (p57) has been associated with isolate virulence and is a diagnostic marker for R. salmoninarum infection. Biological activities of p57 include binding to eukaryotic cells and immunosuppression. We previously isolated three monoclonal antibodies (4D3, 4C11, and 4H8) that neutralize p57 activity. These monoclonal antibodies (MAbs) bind to the amino-terminal region of p57 between amino acids 32 though 243; however, the precise locations of the neutralizing epitopes were not determined. Here, we use transposon mutagenesis to map the 4D3, 4C11, and 4H8 epitopes. Forty-five transposon mutants were generated and overexpressed in Escherichia coli BL21(DE3). The ability of MAbs 4D3, 4H8, and 4C11 to bind each mutant protein was assessed by immunoblotting. Transposons inserting between amino acids 51 and 112 disrupted the 4H8 epitope. Insertions between residues 78 and 210 disrupted the 4C11 epitope, while insertions between amino acids 158 and 234 disrupted the 4D3 epitope. The three MAbs failed to bind overlapping, 15-mer peptides spanning these regions, suggesting that the epitopes are discontinuous in conformation. We conclude that recognition of secondary structure on the amino terminus of p57 is important for neutralization. The epitope mapping studies suggest directions for improvement of MAb-based immunoassays for detection of R. salmoninarum-infected fish.

The C. jejuni LOS loci have been grouped into six classes based on gene content and organization. Utilizing PCR amplifications of genes from these loci, we were able to classify a majority (80%) of the LOS biosynthesis loci from 123 strains of C. jejuni that included 39 of the Penner serotype reference strains. We found that a particular LOS class was not always associated with a specific Penner serotype, and 14 of 16 Guillain-Barre syndrome-associated isolates tested in this study shared the same LOS class. The remaining isolates that could not be classified were often distinguishable from each other based on the results of gene-specific PCR and the lengths of their LOS biosynthesis loci as determined by long (XL) PCR. Sequence analysis of two of these unique XL PCR products demonstrated two new LOS classes. These results support the hypothesis that the LOS locus is a hot spot for genetic exchange and rearrangements. Analysis of the LOS biosynthesis genes by PCR assays can be used for typing C. jejuni and offers the advantage of inferring potential LOS structures.

The doses of AMX active ingredient tested were 0, 5, 10, 30, and 80 mg/kg of fish body weight (BW) per day. Administration of medicated feed started within 22-24 h postchallenge by waterborne exposure to S. iniae (after skin scraping) and continued for 12 consecutive days, followed by a 17-d posttreatment observation. Oral administration of AMX-medicated feed for 12 d at a daily rate of 10, 30, and 80 mg/kg BW significantly increased the survival of S. iniae-infected tilapia from 3.8% in the challenged, nonmedicated positive control to 45, 75, and 93.8%, respectively. The survival rate was significantly higher in the 80-mg treatment (93.75%) than the 10-mg treatment (45%) but did not differ significantly between the 10-mg (45%) and 30-mg (75%) treatments. At the conclusion of the experiment, no carriers were detected in any challenged group receiving AMX-medicated diet, whereas the bacterium was recovered from the nonmedicated, challenged survivors of the infection.

Key purposes of the ESA are "to provide a means whereby the ecosystems upon which endangered species and threatened species depend may be conserved, [and] to provide a program for the conservation of such endangered species and threatened species" (ESA section 2(b)). "Endangered species" is defined as any species (or subspecies or, for vertebrates, "distinct population segment") which is in danger of extinction throughout all or a significant portion of its range, whereas "threatened species" is any species which is likely to become an endangered species within the foreseeable future (ESA section 3). The ESA does not define "foreseeable future."

The isozyme was constitutively expressed in some additional maize tissues and lines examined, and frequently induced by mechanical damage, heat shock, Fusarium proliferatum, and/or Bacillus subtilis in other lines tested. Native/IEF two-dimensional electrophoresis identified the isozyme as the previously genetically identified px5. A cDNA clone expressed in black Mexican sweet (BMS) maize cell cultures produced the pI 9.0 isozyme. In addition to potential use in marker-assisted breeding, enhanced expression of this cationic peroxidase through breeding or genetic engineering may lead to enhanced disease or insect resistance.

Cloacal swabs from market-weight turkeys in each of five flocks were obtained on a farm prior to loading (time 1; 120 swabs per flock) and after transport and holding at the abattoir (time 2; 120 swabs per flock). A statistically significant increase in the overall prevalence of Campylobacter spp. was observed for cloacal swabs obtained from farm 3 following transport (P < 0.01). At time 2, an increase in the prevalence of C. coli was also noted for cloacal swabs from farms 3, 4, and 5 (P < 0.01). Neither the minimum time off of feed nor the distance transported from the farm to the abattoir was correlated with the increase in C. coli prevalence. Similarly, responses to an on-farm management questionnaire failed to detect any factors contributing to the observed changes in Campylobacter sp. prevalence. A SmaI macrorestriction analysis of Campylobacter sp. isolates recovered from flock 5 indicated that C. coli was more diverse than C. jejuni at both time 1 and time 2 (P < 0.01), based on a comparison of the Shannon indices of diversity and evenness.

We tested this system for production of primary fatty amides from hydroxy fatty acids including the naturally occurring mono-hydroxy fatty acids, ricinoleic acid (RA) and lesquerolic acid (LQA) and the novel multihydroxy fatty acids, 7, 10-dihydroxy-8(E)-octadecenoic acid (DOD) and 7, 10, 12-trihydroxy-8(E)-octadecenoic acid (TOD). Reactions were performed at temperatures up to 55 C. Ricinoleic acid and lesquerolic acid were transformed at initial rates comparable to or better than that of oleic acid, a non-hydroxylated substrate. Transformation percentage at 7 days was better than 95% for all substrates except TOD (93.9%). At 55 C, most reactions approached completion within 1 day. The primary amides of LQA, DOD, and TOD are novel compounds having melting points of 73, 105, and 100 C, respectively.

The pectins with higher degrees of esterification induced a stronger molecular association with the nonpolar fragrance. This resulted in a prolonged duration of fragrance release and the limitation of fragrance adsorption to the receptor skin layers. The increase in pectin concentrations suppressed the fragrance release by a diffusion mechanism. Blocking the carboxyl groups of pectin with calcium ions reduces the hydrophilicity of pectin and provides physical barriers for citronellal diffusion. The pectin/calcium microparticles are promising materials for controlled fragrance release.

Soybean volatiles were analyzed using a solid phase microextraction (SPME) method combined with gas chromatography-mass spectrometry (GC-MS). Twenty-one compounds, including 11 aldehydes, three alcohols, four ketones, one furan, one alkane, and one alkene were detected in the LOX normal soybean line. However, only nine volatile compounds were observed in the LOX deficient soybean variety. The antifungal aldehydes hexanal and (E)-2-hexenal were observed in both LOX normal and LOX deficient lines and were detected at significantly higher amounts in soybean homogenate with added lipase. These aldehydes may be formed through alternate pathways, other than the LOX pathway, and may account for the inhibition of A. flavus growth observed. Other volatiles detected, particularly the ketones and alcohols, may contribute to the antifungal activity observed in both LOX normal and LOX deficient soybean lines. These results suggest that other factors, other than LOX activity, may better explain why soybeans are generally not as severely affected by A. flavus and aflatoxin contamination as other oilseed crops.

Dilute H sub(2)SO sub(4) pretreatments at varied temperature (120-190 degree C) and enzymatic saccharification (45 degree C, pH 5.0) were evaluated for conversion of rice hull cellulose and hemicellulose to monomeric sugars. The maximum yield of monomeric sugars from rice hulls (15%, w/v) by dilute H sub(2)SO sub(4) (1.0%, v/v) pretreatment and enzymatic saccharification (45 degree C, pH 5.0, 72 h) using cellulase, beta -glucosidase, xylanase, esterase, and Tween 20 was 287 plus or minus 3 mg/g (60% yield based on total carbohydrate content). Under this condition, no furfural and hydroxymethyl furfural were produced. The yield of ethanol per L by the mixed sugar utilizing recombinant Escherichia coli strain FBR 5 from rice hull hydrolyzate containing 43.6 plus or minus 3.0 g fermentable sugars (glucose, 18.2 plus or minus 1.4 g; xylose, 21.4 plus or minus 1.1 g; arabinose, 2.4 plus or minus 0.3 g; galactose, 1.6 plus or minus 0.2 g) was 18.7 plus or minus 0.6 g (0.43 plus or minus 0.02 g/g sugars obtained; 0.13 plus or minus 0.01 g/g rice hulls) at pH 6.5 and 35 degree C. Detoxification of the acid- and enzyme-treated rice hull hydrolyzate by overliming (pH 10.5, 90 degree C, 30 min) reduced the time required for maximum ethanol production (17 plus or minus 0.2 g from 42.0 plus or minus 0.7 g sugars per L) by the E. coli strain from 64 to 39 h in the case of separate hydrolysis and fermentation and increased the maximum ethanol yield (per L) from 7.1 plus or minus 2.3 g in 140 h to 9.1 plus or minus 0.7 g in 112 h in the case of simultaneous saccharification and fermentation.

Plants may compensate for the effects of herbivory, especially under favourable growing conditions, limited competition, and minimal top-down regulation. These conditions characterise many disturbed wetlands dominated by introduced plants, implying that exotic, invasive weeds in these systems should exhibit strong compensatory responses. 2. The Australian native Melaleuca quinquenervia is highly invasive in the Florida Everglades, U.S.A., where it experiences limited competition or herbivory from native species, making it a likely candidate for compensation. The introduced biological control agent Oxyops vitiosa feeds exclusively on the seasonal flushes of developing foliage at branch apices, which represents approximately 15% of the total foliar biomass. 3. The hypothesis that M. quinquenervia compensates for folivory by O. vitiosa was tested in a series of field-based experiments. Trees experiencing folivory over four consecutive years maintained similar levels of foliar biomass after attack yet possessed twice the number of leaf-bearing terminal stems as undamaged trees. The biomass of these stems was similar among attacked and unattacked trees, indicating that herbivore-damaged trees produce greater quantities of smaller terminal branches. However, undamaged trees were 36 times more likely to reproduce than herbivore-damaged trees. 4. In a separate herbivore exclusion study, a single bout of herbivory on previously undamaged M. quinquenervia trees caused an 80% reduction in reproductive structures the following season. Herbivore-damaged trees also possessed 54% fewer fruits than undamaged trees. An increase in the herbivory frequency (two bouts per year) or magnitude (100% simulated herbivory) did not result in a further reduction in fitness. 5. It has been concluded that M. quinquenervia partially compensates for herbivory by producing new stems and replacing foliage, but this compensation results in a substantial reduction in reproduction.

In contrast to the majority of herbivorous insects, grasshoppers as a group are largely polyphagous. Due to this relative lack of intimate grasshopper-plant associations, grasshopper-plant systems have not played a large part in the study of host-associated genetic differentiation. The oligophagous grasshopper, Hesperotettix viridis (Thomas), is endemic to North America and feeds on composites (Asteraceae) within the tribe Astereae. Previous work has shown both preference and performance differences between H. viridis individuals feeding on either Solidago mollis or Gutierrezia sarothrae. Using 222 AFLP markers, we examined the genetic relationships among 38 H. viridis individuals feeding on these plants both in sympatry and allopatry. Neighbour-joining analysis resulted in two distinct host-associated clades with 71% bootstrap support for host-associated monophyly. Analyses of molecular variation (amova) revealed significant genetic structuring with host plant accounting for 20% of the total genetic variance while locality accounted for 0%. Significant genetic differentiation was detected between S. mollis-feeders and G. sarothrae-feeders even when the two were present at the same locality. These results are consistent with observed differences in preference and performance between H. viridis grasshoppers feeding on either G. sarothrae or S. mollis and indicate that H. viridis is comprised of at least two genetically distinct host plant-associated lineages.

Both linear and nonlinear models were used to model temperature-dependent development and population growth for C. decolora reared on asparagus and artificial diet. We used [at]Risk Software to bootstrap model parameters so that variability in observations could be incorporated into model predictions. C. decolora eggs required approximately 69 DD to complete development with a base temperature of 7.8 degree C. C. decolora developed through four to six instars depending on temperature and food source. Development of larvae from neonate through prepupa required 341.4 DD above a base of 7.3 degree C on asparagus, whereas 254.5 DD were needed on artificial diet, where the base temperature was 7.7 degree C. Pupae required approximately 236 DD (base temperature 8.2-8.4 degree C) to develop when reared on asparagus or artificial diet. Female moths laid significantly more eggs at 14.6 and 20.1 degree C than at higher or lower temperatures. Survival of individuals to the adult stage increased from 71% at 9.7 degree C to 93% at 24.9 degree C. Survival fell off rapidly to 25% at 29.5 degree C. The generation time was the shortest at 29.5 degree C; however, only 25% of females survived to the adult stage, fecundity was low, and only 53% of the eggs hatched. The capacity for increase, r sub(c), was low at 9.7 degree C, peaked at 25.7 degree C, and declined as temperature increased. We estimated that populations on asparagus would not develop at temperatures >31.3 degree C or <6.9 degree C. We show the importance of estimating a range of values for base temperature and degree-days by conducting a preliminary pathway analysis that incorporates the effect of temperature on egg hatch.

Raw poultry products have been implicated as a significant source of these infections. Five trials were conducted to determine whether Campylobacter and Salmonella spp. exist naturally in the mature and immature ovarian follicles of late-life broiler breeder hens. Broiler breeder hens ranging from 60 to 66 wk of age were obtained from four different commercial breeder operations. For each trial, the hens were removed from the commercial operation and held overnight at the University of Georgia processing facility. The hens were euthanized, defeathered, and aseptically opened. To reduce the possibility of cross-contamination between samples, first the mature and immature ovarian follicles, then the ceca, were aseptically removed. Individual samples were placed in sterile bags, packed on ice, and transported to the laboratory for evaluation. Overall, Campylobacter was found in 7 of 55 immature follicles, 12 of 47 mature follicles, and 41 of 55 ceca. Campylobacter was found in at least one of each sample of mature follicles and in ceca in each of the five trials. Salmonella was found in 0 of 55 immature follicles, 1 of 47 mature follicles, and 8 of 55 ceca. In this study, the recovery rate of Salmonella from late-life broiler breeder hen ovarian follicles was relatively low. However, the recovery rate of Campylobacter from the hen ovarian follicles was reasonably high, suggesting that these breeder hens could be infecting fertile hatching eggs. Determining how Campylobacter contaminated these ovarian follicles and how many chicks could be colonized from this source are the next steps in helping to elucidate a better understanding of this ecology and the control of Campylobacter in poultry production.Original Abstract: Nota de Investigacion-Presencia natural de Campylobacter y Salmonella en foliculos ovaricos maduros e inmaduros de reproductoras de engorde en la etapa final de su ciclo productivo.El Campylobacter y la Salmonella son agentes conocidos como causantes de la gastroenteritis bacteriana aguda en humanos. Los alimentos crudos de origen avicola han sido implicados como una fuente significativa de esta infeccion. Se realizaron 5 experimentos para determinar si las especies de Campylobacter y Salmonella existen de forma natural en los foliculos ovaricos maduros e inmaduros de reproductoras de engorde en la etapa final de su ciclo productivo. Se obtuvieron reproductoras de engorde entre 60 y 66 semanas de edad a partir de 4 operaciones diferentes de reproductoras de engorde. En cada experimento, las reproductoras fueron removidas de la operacion comercial y mantenidas durante la noche en las instalaciones del matadero de la Universidad de Georgia. Las aves fueron sacrificadas, desplumadas, y asepticamente se procedio a realizar la necropsia. Con el fin de reducir la posibilidad de contaminacion cruzada entre las muestras, se removieron inicialmente los foliculos ovaricos maduros e inmaduros y luego los ciegos. Las muestras individuales fueron depositadas en bolsas esteriles, colocadas en hielo, y transportadas al laboratorio para ser evaluadas. En general, se encontro Campylobacter en 7 de 55 foliculos inmaduros, 12 de 47 foliculos maduros, y 41 de 55 ciegos. Se encontro Campylobacter en por lo menos una de cada muestra de foliculos maduros y ciegos en cada uno de los 5 experimentos. Se encontro Salmonella en 0 de 55 foliculos inmaduros, 1 de 47 foliculos maduros, y 8 de 55 ciegos. En este estudio, el indice de recuperacion de Salmonella a partir de los foliculos ovaricos de reproductoras de engorde en la etapa final de su ciclo productivo fue relativamente bajo. Sin embargo, el indice de recuperacion de Campylobacter a partir de foliculos ovaricos de reproductoras de engorde fue razonablemente alto, lo cual sugiere que estas reproductoras podrian estar infectando huevos fertiles incubables. La determinacion del mecanismo de contaminacion de los foliculos ovaricos por Campylobacter y del numero de pollitos que podrian ser colonizados mediante esta fuente son los pasos siguientes a resolver para poder tener un mejor conocimiento de la ecologia y el control de Campylobacter en las empresas avicolas.

The commercialization of synthetic EAPs, however, has so far been severely limited. Biological polymers offer a degree of functionality not available in most synthetic EAPs. Carbohydrate polymers are produced with great frequency in nature. Starch, cellulose, and chitin are some of the most abundant natural polymers on earth. Biopolymers are a renewable resource and have a wide range of uses in nature, functioning as energy storage, transport, signaling, and structural components. In general, electroactive materials with polysaccharide matrices reach conductance levels comparable with synthetic ion-conducting EAPs. This review gives a brief history of EAPs, including terminology, describes evaluation methods, and reports on the current progress of incorporating polysaccharides as matrices for doped, blended, and grafted electroactive materials.

We evaluated the effects of constant and variable rainfall intensities on the transport characteristics and amount of sediment organic carbon lost from two highly weathered Coastal Plain soils in Georgia - a Tifton loamy sand (Plinthic Kandiudult) and a Greenville sandy clay loam (Rhodic Kandiudult). Soils were air-dried, sieved (19 mm) and placed in 1.5 m super(2) stainless steel erosion pans set to match typical field slopes for each soil (Tifton = 4 percent; Greenville = 7 percent). Simulated rainfall was applied for 70-min as a constant (57 mm h super(-1)) or variable (typical spring storm) event pattern. Runoff, sediment, sediment carbon, sediment nitrogen, and dissolved carbon were measured at five-minute intervals. Regardless of simulation intensity evaluated, sediment exported from the Tifton soil was enriched (enrichment ratio 1.17 to 1.80) and the Greeneville soil depleted (0.83 to 0.93) in carbon relative to the top 2 cm of undisturbed soil. Only minor (not significant) differences were observed in the potential for total sediment carbon loss estimated by the two simulation intensities (Tifton, 5.65-6.67 kg ha super(-1) and Greenville, 13.44-14.40 kg ha super(-1)). However, significant differences in the effect of simulation intensities on timing and amount of carbon lost via sediment transport (more during first versus second half of simulation for variable versus constant intensity patterns respectively) were observed during the simulations. Results suggest that detachment and transport thresholds differ for total sediment versus sediment carbon losses during a given event and that variable rate rainfall simulations may be an effective means to characterize threshold differences for individual soil and management combinations. It is suggested that the systematic determination of such thresholds may improve predictions of sediment transported organic contaminants.

P. oleovorans NRRL B-14682 contains Class I PHA synthase gene (phaC), NRRL B-14683 harbors Class II phaC1 and phaC2 genes, and NRRL B-778 contain both the Class I and II PHA synthase genes. Inverse-PCR and chromosomal walking techniques were employed to obtain the complete sequences of the Class I phaCs of NRRL B-778 (phbC sub(778); 1698 bps) and B-14682 (phbC sub(14682); 1899 bps). BLAST search indicated that these genes are new and had not been previously cloned. The gene product of phbC sub(778) (i.e., PhbC sub(778); 566 amino acid residues) is homologous to the Class I PHA synthases ofPseudomonas sp. HJ-2 and Pseudomonas sp. strain 61-3, and that of phbC sub(14682) (PhbC sub(14682); 632 amino acids) is homologous to PHAS ofDelftiaacidovorans. The PhbC sub(14682) contains an extra sequence of 33 amino acids in its conserved alpha / beta -hydrolase domain, making it only the second Class I PHA synthase found to contain this cellular proteolytic sequence. Consistent with their Pseudomonas origin, the codon-usage profiles of PhbC sub(778) and PhbC sub(14682) are similar to those ofPseudomonas Class II PHASs. These new Pseudomonas Class I phbC genes provide valuable addition to the gene pool for the construction of novel PHASs through gene shuffling.

We used previous surveys and our 1997-1998 survey to reconstruct the historical fauna, to describe spatio-temporal patterns of density and number of species, and to evaluate the probable sequence and cause of observed mussel declines. We were specifically interested in better understanding how mussel assemblages respond to chronic disturbances, and how these changes manifest in persistence patterns. Density and numbers of species declined steadily from 1981 to 1998, but declines occurred first in the lower river (early 1980s), followed by declines in the upper river (late 1980s to early 1990s). Of the total species recorded from the Little South Fork, 17 (65%) are seemingly extirpated and five others appear near extirpation. Declines are associated with at least two, temporally distinct major insults. Lower river declines are associated with surface mining, whereas, oil extraction activities are implicated in upper river declines. Regardless of causal factors, species persistence was primarily a function of predecline population size with only the most numerous and widespread species surviving. At this time, the river appears lost as a conservation refugium for mussels despite its remoteness, predominantly forested watershed, and several layers of existing statutory and regulatory environmental safeguards. We suggest that the river could be restored and mussels reintroduced if an interagency task force is formed to identify and mitigate specific stressors now affecting most mussel species in the river.

In a fourth feeding trial, purified FB sub(1) (125 and 274 ppm) and moniliformin (27 and 154 ppm) were given separately and in combination (137 and 77 ppm, respectively). Chicks that died during the trial periods, survivors and controls were subjected to postmortem examination. Specimens (liver, kidney, pancreas, lung, brain, intestine, testis, bursa of Fabricius, heart and skeletal muscle) were examined grossly and preserved for subsequent histopathologic and ultrastructural examination. Prominent gross lesions in affected birds fed diets amended with CM or purified FB sub(1) and moniliformin included ascites, hydropericardium, hepatopathy, nephropathy, cardiomyopathy, pneumonitis, gizzard ulceration, and enlarged bursa of Fabricius filled with caseous material. The various concentrations of FB sub(1 )and moniliformin in the amended rations produced well-defined dose-response lesions in all groups in all four trials. Histopathologic changes included hemorrhage, leucocytic infiltration, fatty change or infiltration, individual cell necrosis and fibrosis in liver, kidneys, lungs, heart, intestines, gizzard, bursa of Fabricius and pancreas. Edema and hemorrhage were prominent in brains of treated birds. Ultrastructural changes included cytoplasmic and nuclear enlargement of cells in affected liver, lungs, kidneys, heart and pancreas. There were thickened membranes of the smooth endoplasmic reticulum, dilation of the rough endoplasmic reticulum with loss of ribosomes and vacuolated or deformed mitochondria.

The 'Biologically Identified Optimal Temperature Interactive Console (BIOTIC)' is an irrigation protocol that provides irrigation scheduling based upon measurements of canopy temperatures and the temperature optimum of the crop species of interest. One of the goals of this paper is to document the gradual development of the method and its implementation. Two threshold values are required to implement BIOTIC irrigation of a crop in a given region, a species-specific temperature threshold and a species/environment-specific time threshold. The temperature threshold, an indication of the thermal optimum for the plant, is derived from the thermal dependence of its metabolism. The time threshold, which represents the average amount of time each day that the canopy temperature of the well-watered crop will exceed the temperature threshold, is calculated from weather data. Interest in the use of BIOTIC for irrigation scheduling for peanut ( Arachis hypogaea L.) resulted in this study in which the temperature and time thresholds for peanut were determined on the Texas Southern High Plains. A temperature threshold value of 27 degree C was determined from the thermal dependence of the reappearance of photosystem II variable fluorescence (PSII Fv) following illumination. A time threshold of 405 min was calculated from an analysis of weather data collected over the course of the 1999 growing season. The determination of these threshold values for peanut provides the basis for the application of the BIOTIC protocol to irrigation scheduling of peanut on the Southern High Plains of Texas.

AN - 67849306; 15790562 AB - Ubiquitin plays essential roles in various cellular processes; therefore, it is of keen interest to study the structure-function relationship of ubiquitin itself. We investigated the modification of Lys(6) of ubiquitin and its physiological consequences. Mass spectrometry-based peptide mapping and N-terminal sequencing demonstrated that, of the 7 Lys residues in ubiquitin, Lys(6) was the most readily labeled with sulfosuccinimidobiotin. Lys(6)-biotinylated ubiquitin was incorporated into high molecular mass ubiquitin conjugates as efficiently as unmodified ubiquitin. However, Lys(6)-biotinylated ubiquitin inhibited ubiquitin-dependent proteolysis, as conjugates formed with Lys(6)-biotinylated ubiquitin were resistant to proteasomal degradation. Ubiquitins with a mutation of Lys(6) had similar phenotypes as Lys(6)-biotinylated ubiquitin. Lys(6) mutant ubiquitins (K6A, K6R, and K6W) also inhibited ATP-dependent proteolysis and caused accumulation of ubiquitin conjugates. Conjugates formed with K6W mutant ubiquitin were also resistant to proteasomal degradation. The dominant-negative effect of Lys(6)-modified ubiquitin was further demonstrated in intact cells. Overexpression of K6W mutant ubiquitin resulted in accumulation of intracellular ubiquitin conjugates, stabilization of typical substrates for ubiquitin-dependent proteolysis, and enhanced susceptibility to oxidative stress. Taken together, these results show that Lys(6)-modified ubiquitin is a potent and specific inhibitor of ubiquitin-mediated protein degradation.

AN - 67820513; 15884871 AB - Two steers (approximately 195 kg) were each dosed with 62.5 or 130.6 mg/kg body weight sodium [36Cl]chlorate for three consecutive days. All excreta were collected during the dosing and 8 h withdrawal periods. The apparent radiochlorine absorption was 62-68% of the total dose with the major excretory route being urine. Parent chlorate was 65-100% of the urinary radiochlorine; chloride was the only other radiochlorine species present. Similarly, residues in edible tissues were composed of chloride and chlorate with chloride being the major radiolabeled species present. Chlorate represented 28-57% of the total radioactive residues in skeletal muscle; in liver, kidney, and adipose tissues, chlorate ion represented a smaller percentage of the total residues. Chlorate residues in the low dose steer were 26 ppm in kidney, 14 ppm in skeletal muscle, 2.0 ppm in adipose tissue, and 0.7 ppm in liver. These data indicate that sodium chlorate may be a viable preharvest food safety tool for use by the cattle industry.

Although stress and cortisol secretion are highly correlated in fish, the role of cortisol in affecting channel catfish (Ictalurus punctatus) pathogen susceptibility is unclear. The effects of short-term stress and exogenous cortisol administration on channel catfish susceptibility to Edwardsiella ictaluri, the etiologic agent of enteric septicemia of catfish (ESC), were investigated. Channel catfish were exposed to virulent E. ictaluri following a standardized 30-min low-water stress or administration of dietary cortisol (100mg/kg feed) and compared to a pathogen-challenged control group of catfish. Pathogen susceptibility increased in stressed catfish (43.3% mortality) when compared to cortisol-fed catfish (26.7%) and controls (26.7%). A greater (P0.05) among the treatments. Catfish challenged by the low-water stress event had elevated (P0.05) to either lysozyme activity or bacterial levels; however, lysozyme activity was positively correlated (P=0.0197) to blood bacterial concentrations. These results implicate other stress factors or pathways, separate from or possibly in conjunction with cortisol, in the stress-associated immunosuppression of channel catfish as it relates to ESC susceptibility.

AN - 68033703; 16018316 AB - The maize endophyte Acremonium zeae is antagonistic to kernel rotting and mycotoxin producing fungi Aspergillus flavus and Fusarium verticillioides in cultural tests for antagonism, and interferes with A. flavus infection and aflatoxin contamination of preharvest maize kernels. Chemical studies of an organic extract from maize kernel fermentations of Acremonium zeae (NRRL 13540), which displayed significant antifungal activity against Aspergillus flavus and F. verticillioides, revealed that the metabolites accounting for this activity were two newly reported antibiotics pyrrocidines A and B. Pyrrocidines were detected in fermentation extracts for 12 NRRL cultures of Acremonium zeae isolated from maize kernels harvested in Illinois (4/4 cultures), North Carolina (5/5), Georgia (1/2) and unrecorded locations within the USA (2/2). Pyrrocidine B was detected by LCMSMS in whole symptomatic maize kernels removed at harvest from ears of a commercial hybrid that were wound-inoculated in the milk stage with A. zeae (NRRL 13540) or (NRRL 13541). The pyrrocidines were first reported from the fermentation broth of an unidentified filamentous fungus LL-Cyan426, isolated from a mixed Douglas Fir hardwood forest on Crane Island Preserve, Washington, in 1993. Pyrrocidine A exhibited potent activity against most Gram-positive bacteria, including drug-resistant strains, and was also active against the yeast Candida albicans. In an evaluation of cultural antagonism between 13 isolates of A. zeae in pairings with A. flavus (NRRL 6541) and F. verticillioides (NRRL 25457), A. zeae (NRRL 6415) and (NRRL 34556) produced the strongest reaction, inhibiting both organisms at a distance while continuing to grow through the resulting clear zone at an unchanged rate. Maximum colony diameters for A. zeae (NRRL 6415) and (NRRL 13540), on potato dextrose agar after 14 d, were attained within the range of 25-30 degrees C, with less growth recorded at 15 degrees and 37.5 degrees and no growth at 5 degrees.

AN - 67944778; 15962779 AB - Nepetalactone, the primary component of catnip oil, was compared with the repellent N,N-diethyl-3-methylbenzamide (deet) for its ability to affect the host-seeking ability of Aedes aegypti (L.). A triple cage olfactometer was used to bioassay each substance and to assess its attraction inhibition (spatial repellent) attributes when combined with the following attractants: carbon dioxide, acetone, a blend of L-lactic acid and acetone, and human odors. Repellent tests were conducted with each substance against female Ae. aegypti, Anopheles albimanus Weidemann, and Anopheles quadrimaculatus Say. Catnip oil and deet were both weakly attractive to Ae. aegypti, catnip oil was the better spatial repellent, whereas deet was a more effective contact repellent in tests with all three species of mosquitoes.

AN - 67879455; 15921409 AB - Ammodendrine (1) was found to occur as a mixture of enantiomers in two different collections of plants identified as Lupinus formosus. The ammodendrine fraction was reacted in a peptide coupling reaction with 9-fluorenylmethoxycarbonyl-L-alanine (Fmoc-L-Ala-OH) to give diastereomers, which were separated by preparative HPLC. The pure D- and L-ammodendrine enantiomers were then obtained by Edman degradation. Optical rotation measurements revealed that the D- and L-enantiomers had optical rotations of [alpha]24D +5.4 and -5.7, respectively. D- and L-N-methylammodendrine enantiomers were synthesized from the corresponding ammodendrine enantiomers, and their optical rotations established as [alpha]23D +62.4 and -59.0, respectively. A mouse bioassay was used to determine the difference in toxicity between these two pairs of naturally occurring enantiomers. The LD50 of (+)-D-ammodendrine in mice was determined to be 94.1 +/- 7 mg/kg and that of (-)-L-ammodendrine as 115.0 +/- 7 mg/kg. The LD50 of (+)-D-N-methylammodendrine in mice was estimated to be 56.3 mg/kg, while that of (-)-L-N-methylammodendrine was determined to be 63.4 +/- 5 mg/kg. These results establish the rotation values for pure ammodendrine and N-methylammodendrine and indicate that there is little difference in acute murine toxicity between the respective enantiomers.

AN - 67833422; 15895730 AB - Samples from environmental sites and raw product in a chicken further processing plant were collected every 6 weeks for 12 months. Each sample site was examined before and after a complete production shift. All samples were examined for the presence of Listeria monocytogenes, which was detected in floor drains on the raw product side of the plant preoperation and in drains on both raw and cooked sides following 8 h of processing operation. L. monocytogenes also was detected in raw product and once in fully cooked product but never on cooked product contact surfaces. One hundred sixty-one isolates were collected from 75 positive samples. All isolates were subtyped using a sequence-based method, and 14 unique subtypes were detected through the course of the study. Four of these types were found repeatedly and appeared to be resident in the plant. Three of the four resident strains were detected on raw product at some point during the year-long study, suggesting that raw product may be one source of L. monocytogenes in the processing plant environment. These data highlight the need for research to investigate why some types of L. monocytogenes persist in a processing plant environment but others do not.

AN - 67821022; 15888894 AB - Tropospheric ozone is an air pollutant that is toxic to plants, causing visible injury to foliage and a reduction in growth and yield. The use of plant bioindicators is one approach to assess the ozone impacts in diverse geographical areas. The objective of this study was to evaluate snap bean (Phaseolus vulgaris L.) as a potential bioindicator species. Three snap bean genotypes known to exhibit a range of ozone sensitivity were grown in pots under charcoal-filtered (CF) or nonfiltered (NF) treatments in open-top chambers, or under ambient air (AA) conditions. Treatment effects on biomass were not significant at 56 days after planting (DAP), but midseason foliar injury increased in the NF and AA treatments relative to CF controls. An increase in ozone from 25 to 30 nL L(-1) in CF controls to approximately 50 nL L(-1) in the NF and AA treatments was found to suppress final pod dry weight per plant by 40 to 60% in the most sensitive genotype S156. The same treatments suppressed final pod dry weight by 20 to 30% in a moderately sensitive genotype Oregon-91, and by 10% or less in a tolerant genotype R123. An S156 to R123 yield ratio of approximately one was observed under CF conditions. The S156 to R123 yield ratio declined to 0.6 to 0.7 in the NF treatment and declined further to 0.4 to 0.5 in the AA treatment, suggesting that ozone impact was underestimated in the open-top chambers. The results suggest that a snap bean bioindicator system has the potential to detect ambient ozone effects at present-day ozone concentrations.

AN - 67791666; 15870357 AB - Food-borne illness caused by Salmonella enterica has been linked traditionally to poultry products but is associated increasingly with fresh fruits and vegetables. We have investigated the role of the production of autoinducer 2 (AI-2) in the ability of S. enterica serovar Thompson to colonize the chicken intestine and the cilantro phyllosphere. A mutant of S. enterica serovar Thompson that is defective in AI-2 production was constructed by insertional mutagenesis of luxS. The population size of the S. enterica serovar Thompson parental strain was significantly higher than that of its LuxS(-) mutant in the intestine, spleen, and droppings of chicks 12 days after their oral inoculation with the strains in a ratio of 1:1. In contrast, no significant difference in the population dynamics of the parental and LuxS(-) strain was observed after their inoculation singly or in mixtures onto cilantro plants. Digital image analysis revealed that 54% of S. enterica serovar Thompson cells were present in large aggregates on cilantro leaves but that the frequency distributions of the size of aggregates formed by the parental strain and the LuxS(-) mutant were not significantly different. Carbon utilization profiles indicated that the AI-2-producing strain utilized a variety of amino and organic acids more efficiently than its LuxS(-) mutant but that most sugars were utilized similarly in both strains. Thus, inherent differences in the nutrients available to S. enterica in the phyllosphere and in the chicken intestine may underlie the differential contribution of AI-2 synthesis to the fitness of S. enterica in these environments.

AN - 67764820; 15843658 AB - Little attention has been paid to the environmental fate of the hormones 17beta-estradiol and testosterone excreted in animal waste. Land application of manure has a considerable potential to affect the environment with these endocrine disrupting compounds (EDCs). Composting is known to decompose organic matter to a stable, humus-like material. The goal of the present study was to quantitatively assess levels of water-soluble 17beta-estradiol and testosterone in composting chicken manure with time. Chicken layer manure was mixed with hay, straw, decomposed leaves, and starter compost, adjusted to approximately 60% moisture, and placed into a windrow. A clay-amended windrow was also prepared. Windrows were turned weekly, and temperature, oxygen, and CO(2) in the composting mass were monitored for either 133 or 139 d. Commercial enzyme immunoassay kits were used to quantitate the levels of 17beta-estradiol and testosterone in aqueous sample extracts. Water-soluble quantities of both hormones diminished during composting. The decrease in 17beta-estradiol followed first-order kinetics, with a rate constant k = -0.010/d. Testosterone levels declined at a slightly higher rate than 17beta-estradiol (i.e., k = -0.015/d). Both hormones could still be measured in aqueous extracts of compost sampled at the conclusion of composting. The decline in water-soluble 17beta-estradiol and testosterone in extracts of clay-amended compost was not statistically different from normal compost. These data suggest that composting may be an environmentally friendly technology suitable for reducing, but not eliminating, the concentrations of these endocrine disrupting hormones at concentrated animal operation facilities.

Numerous concerns (e.g., water quality, on-site waste disposal, landfill placement, and nutrient or pesticide movement) require an integrated knowledge and understanding of soil, the soil-to-substratum transition, and the deeper substratum. Soil C-horizons can exceed the thickness of the overlying A and B-horizons and contain unique morphological properties. The subsolum including C-horizons receives less descriptive emphasis than upper soil horizons. Soil scientists map and classify soils mainly on A and B-horizon properties. Soil forming and hydrologic processes that impart morphological features, however, extend considerably below these horizons. Precise adherence to Soil Taxonomy places an arbitrary constraint on field observations at 2 m. Soil scientists routinely observe C and R horizons and deeper underlying substrata in gravel pits, road cuts, barrow pits, foundation excavations, and drill cores, but provide less documentation than for upper horizons. Parent material and stratigraphy need more consideration in soil map unit design and delineation. Field observations by soil scientists below 2 m are crucial for understanding the subsolum (i.e., the morphology of, and relationships of solum to substratum). Soil surveys can convey concise and more descriptive soil-to-substrata information with little added effort or resources. Soil surveys can accomplish this end by use of block diagrams, parent material maps, and geomorphic maps that include both pedostratigraphic and lithostratigraphic detail. Soil surveys must develop soil and map unit descriptions linked to measured sections and named stratigraphic units, and describe and analyze soils and parent materials to greater depths (>2 m). We use case examples to demonstrate these concepts. Soil-to-substrata documentation and presentation conveys crucial information to soil survey users. Soil-to-substrata relationships identified and recorded during a soil survey create a knowledge window to the subsurface.

This dynamic process, called soil hydrology (also called hydropedology), can be approached within a framework of conceptual models that combine the influences of regional climate (with local variations), stratigraphy (pedo- and geo-stratigraphic circumstances) and topography (macro- and micro-topography). When combined, these elements can provide a practical understanding and prediction of how and where water in the vadose zone will typically move within a landscape. These conceptual models can also be extended to larger land areas, with adjustments made as the elements, such as stratigraphy, vary. In situations where highly detailed monitoring is not cost-effective, soil hydrology provides a means of incorporating what is known about water flow into our understanding, presentation and use of the soilscape. Soil hydrology can, in turn, be used to explain soil features (soil morphology), distributions (soil geography) and ecosystem functions (dynamics). It can also be used to guide land management decisions by providing a basis for partitioning the landscape into subsets with different input tolerances.

Endogenous trehalose also is present in trace amounts in flowering plants and metabolites derived from trehalose were necessary for embryo development. In contrast to its role in endogenous metabolism, exogenous trehalose is toxic to higher plants as evidenced by a severe inhibition of root and cotyledon growth. In the current study, 30 mM trehalose or sterile water was added to 2-week-old liquid cultures containing Arabidopsis thaliana (L.) Henyh seedlings. After 12 h of exogenous trehalose treatment sucrose and trehalose were increased 3.2-and 145- fold, respectively, compared to the controls. These were the only metabolites measured in this study that responded to trehalose treatment at this time point. Starch was increased and ATP levels were decreased in Arabidopsis samples after 1 day of treatment with 30 mM trehalose. Conversely, glutamate, glutamine, hexoses and chlorophyll were unaffected by trehalose treatment. Two-dimensional gel electrophoresis revealed that for whole Arabidopsis seedlings, nine proteins were altered by 12 h of trehalose treatment relative to the controls. Seven of the nine polypeptides were successfully identified by sequence analysis. Four of the identified proteins induced by trehalose treatment, Phi glutathione S- transferase 2 (AtGSTF2), flavin mononucleotide-binding flavodoxin-like quinone reductase 1 (FQR1), cytosolic dehydroascorbate reductase 1 (DHAR1) and S-adenosylmethionine synthetase 2 (SAMS2), were involved in either detoxification or stress responses. The above results indicated that feeding exogenous trehalose to liquid cultures of Arabidopsis seedlings rapidly altered disaccharide levels and induced detoxification and stress response proteins. These findings supported the suggestion that exogenous trehalose functioned as an elicitor of genes involved in biotic and abiotic stress.

Largest reductions are projected in southern crop areas due to increased temperatures and reduced water availability. A longer growing season and projected increases in CO sub(2) may enhance crop yields in northern growing areas. Major factors in these scenarios analyzes are increased drought tendencies and more extreme weather events, both of which are detrimental to agriculture. Increasing competition for water between agriculture and non-agricultural users also focuses attention on water management issues. Agriculture also has impact on the greenhouse gas balance. Forests and soils are natural sinks for CO sub(2). Removal of forests and changes in land use, associated with the conversion from rural to urban domains, alters these natural sinks. Agricultural livestock and rice cultivation are leading contributors to methane emission into the atmosphere. The application of fertilizers is also a significant contributor to nitrous oxide emission into the atmosphere. Thus, efficient management strategies in agriculture can play an important role in managing the sources and sinks of greenhouse gases. Forest and land management can be effective tools in mitigating the greenhouse effect.

Current methods of quantifying crop residue cover are inadequate for characterizing the spatial variability of residue cover within fields and across large regions. Our objectives were to evaluate several spectral indices for measuring crop residue cover using ground-based and airborne hyperspectral data and to categorize soil tillage intensity in agricultural fields based on crop residue cover. Reflectance spectra of mixtures of crop residues, green vegetation, and soil were acquired over the 400- to 2500-nm wavelength region. High-altitude AVIRIS (Airborne Visible Infrared Imaging Spectrometer) data were also acquired near Beltsville, MD, in May 2000. Broad absorption features near 2100 and 2300 nm in the reflectance spectra of crop residues were associated with cellulose and lignin. These features were not evident in the spectra of green vegetation and soils. Crop residue cover was linearly related to the cellulose absorption index, which was defined as the relative depth of the 2100- nm absorption feature. Other spectral indices for crop residue were calculated and evaluated. The best spectral indices were based on relatively narrow (10-50 nm) bands in the 2000- to 2400-nm region, were linearly related to crop residue cover, and correctly identified tillage intensity classes in >90% of test agricultural fields. Regional surveys of soil management practices that affect soil conservation and soil C dynamics may be feasible using advanced multispectral or hyperspectral imaging systems.

However, the proton motive force ( Delta p) was only -25 mV, and protonophores did not inhibit growth. When extracellular pH was decreased with HCl, the chemical gradient of protons (Z Delta pH) and the electrical membrane potential ( Delta psi ) increased. The Delta p was -125 mV at pH 4.7, even though growth was not observed. At pH 6.7, glucose addition did not cause an increase in growth rate, but Delta psi increased to -70 mV. Protein synthesis inhibitors also significantly increased Delta psi . Non-growing, arginine-energized cells had a Delta psi of -80 mV at pH 6.7 or pH 4.7, but Delta psi was not detected if the F sub(1)F sub(0) ATPase was inhibited. Arginine-energized cells initiated growth if other amino acids were added at pH 6.7, and Delta psi and ATP declined. At pH 4.7, ATP production remained high. However, growth could not be initiated, and neither Delta psi nor the intracellular ATP concentration declined. Based on these results, it appears that C. sporogenes MD1 does not need a large Delta p to grow, and Delta p appears to serve as a mechanism of ATP dissipation or energy spilling.

For agronomic and horticultural plants, specific adaptation information has been and continues to be developed by extensive testing. Rangeland, grassland, park, and restoration project managers often lack the resources to determine adaptation areas for plant materials because of the large number of species that are used and the extensive geographical areas that are serviced. Problems often arise in delineating adaptation areas for plant materials of both native and introduced species. Since ecoregion and plant hardiness zone classification systems integrate many climatic and geographic variables that determine plant adaptation, these 2 systems can be combined to develop Plant Adaptation Regions (PARs). A PAR map of the contiguous United States was developed by merging a widely used ecoregion map with the USDA Plant Hardiness Zone map, and is available in GIS format. Based on their geographic origins and/or test results, plant materials and their general areas of adaptation can be classified using PARs.Original Abstract: El uso efectivo de materiales de plantas para un grupo de objetivos, incluyendo la conservacion, restauracion, renovacion, jardineria y bioeremediacion, requiere del conocimiento de la adaptacion de cada especie, y mas especificamente de los cultivares, lineas o ecotipos de una especie a regiones o sitios especificos. En el caso de especies horticolas o de uso agronomico la informacion sobre la adaptacion especifica ha sido y continua siendo desarrollada mediante la pruebas extensivas. Sin embargo, los manejadores de proyectos de restauracion de pastizales, parques y praderas a menudo carecen de recursos para determinar las areas de adaptacion para las especies vegetales debido al gran numero de especies que son usadas y las areas geograficas tan extensas en las que son evaluadas. Los problemas a menudo surgen en delinear areas de adaptacion para los materiales vegetales tanto de especies nativas como introducidas. Dado que los sistemas de clasificacion de ecoregiones y zonas de resistencia de las plantas integran muchas variables climaticas y geograficas que determinan la adaptacion de las plantas, ellas pueden se combinadas para desarrollar Regiones de Adaptacion de Plantas (PAR). Un mapa PAR adyacente de Estados Unidos se desarrollo uniendo un mapa de ecoregion, ampliamente utilizado y un mapa de Zona de Resistencia de Planta del Departamento de Agricultura de los Estados Unidos (USDA) que esta disponible en formato de sistemas de informacion geografica (GIS). Basados en su origen geografico y/o resultados de evaluaciones, los materiales de plantas y sus areas generales de adaptacion pueden ser clasificadas usando las Regiones de Adaptacion de Plantas.

Suspensions of E. coli were exposed to 0.5 mg L super(-1) of chlorine for 5 min followed by dechlorination with sodium thiosulfate. The chlorine-exposed bacteria were introduced into 2-L microcosms containing estuarine water collected from the Seacost region of New Hampshire. Culturable cells in the microcosms were enumerated at 0, 10, 24, 48, and 74 h. In all estuarine microcosms the number of culturable cells increased by factors ranging from 2.8 to 50 over the 74-h incubation period. Multiple linear regression analyses indicated that ammonium and salinity were most significantly correlated with the recovery of E. coli over the 74-h incubation period; however, ammonium concentrations were strongly correlated with dissolved organic carbon and total dissolved nitrogen, making it impossible to determine with any degree of certainty the unique effect nitrogen or carbon had on recovery. The extensive recovery observed in our study indicates that following exposure to concentrations of chlorine that cause cell injury rather than death, numbers of culturable E. coli may increase significantly when discharged into estuarine waters. Thus, depending on the effectiveness of the chlorination process, the regular monitoring of chlorinated wastewater treatment effluent may underestimate the true impact on water-quality and public health risks.

Several researchers at the ARS Aquatic Animal Health Research Unit in Auburn, Alabama-along with one from their laboratory in Chestertown, Maryland-are working mainly with catfish and to a lesser extent with tilapia, hybrid striped bass, and several other species of fish, to develop fish vaccines to protect against diseases. Many of the diseases kill the fish, which means less profit for the producer and higher prices for consumers. Over the last few years, the laboratory has either patented or applied for patents for several fish vaccines. "It takes about 2 to 4 years of research to get to the point where we can apply for a patent," explains microbiologist Craig A. Shoemaker. He's helped to develop several vaccines in Auburn.

This study quantified the effects of tillage and nutrient source on tile line and surface inlet water quality under continuous corn (Zea mays L.) from relatively flat lands (<3%). Tillage treatments were either fall chisel or moldboard plow. Nutrient sources were either fall injected liquid hog manure or spring incorporated urea. The experiment was on a Webster- Canisteo clay loam (Typic Endoaquolls) at Lamberton, MN. Surface inlet runoff was analyzed for flow, total solids, NO sub(3)-N, NH sub(4)-N, dissolved P, and total P. Tile line effluent was analyzed for flow, NO sub(3)-N, and NH sub(4)-N. In four years of rainstorm and snowmelt events there were few significant differences (p < 0.10) in water quality of surface inlet or tile drainage between treatments. Residue cover minimally reduced soil erosion during both snowmelt and rainfall runoff events. There was a slight reduction in mineral N losses via surface inlets from manure treatments. There was also a slight decrease (p = 0.025) in corn grain yield from chisel-plow plots (9.7 Mg ha super(-1)) compared with moldboard-plow plots (10.1 Mg ha super(-1)). Chisel plowing (approximately 30% residue cover) alone is not sufficient to reduce nonpoint source sediment pollution from these poorly drained flat lands to the extent (40% reduction) desired by regulatory agencies.

While different forms of Se vary in their anticarcinogenic efficacy, Se-methylselenocysteine (SeMSC) has been demonstrated to be one of the most effective chemopreventative compounds. Broccoli (Brassica oleracea var. italica) is known for its ability to accumulate high levels of Se with the majority of the selenoamino acids in the form of Se-methylselenocysteine. Therefore, it serves as a good model to study the regulation of SeMSC accumulation in plants. A cDNA encoding selenocysteine Se-methyltransferase, the key enzyme responsible for SeMSC formation, was cloned from broccoli using a homocysteine S-methyltransferase gene probe from Arabidopsis (Arabidopsis thaliana). This clone, designated as BoSMT, was functionally expressed in Escherichia coli, and its identity was confirmed by its substrate specificity in the methylation of selenocysteine. The BoSMT gene represents a single copy sequence in the broccoli genome. Examination of BoSMT gene expression and SeMSC accumulation in response to selenate, selenite, and sulfate treatments showed that the BoSMT transcript and SeMSC synthesis were significantly up-regulated in plants exposed to selenate but were low in plants supplied with selenite. Simultaneous treatment of selenate with selenite significantly reduced SeMSC production. In addition, high levels of sulfate suppressed selenate uptake, resulting in a dramatic reduction of BoSMT mRNA level and SeMSC accumulation. Our results reveal that SeMSC accumulation closely correlated with the BoSMT gene expression and the total Se status in tissues and provide important information for maximizing the SeMSC production in this beneficial vegetable plant.

Rapid and timely information about manure nutrient content are needed to minimize the risks of phosphorus (P) over-application and losses of dissolved P (DP) in runoff from fields treated with manure. We evaluated the suitability of a commercial hand-held reflectometer, a hydrometer, and an electrical conductivity (EC) meter for determining DP and total P (TP) in dairy manures. Bulk samples (n = 107) collected from farms across CT, MD, NY, PA, and VA were highly variable in total solids (TS) concentration, ranging from 11 to 213 g L super(-1), in suspensions' pH (6.3-9.2), and EC (6.2-53.3 dS m super(-1)). Manure DP concentrations measured using the RQFlex reflectometer (RQFlex-DP sub(s)) were related to molybdate-reactive P (MRP sub(s)) concentrations as follows: RQFlex- DP sub(s) = 0.471 x MRP sub(s) + 1102 (r super(2) = 0.29). Inclusion of pH and squared-pH terms improved the prediction of manure DP from RQFlex results (r super(2) = 0.66). Excluding five outlier samples that had pH [precedesorequalto] 6.9 the coefficient of determination (r super(2)) for the MRP sub(s) and RQFlex-DP sub(s) relationship was 0.83 for 95% of the samples. Manure TS were related to hydrometer specific gravity readings (r super(2) = 0.53) that were in turn related to TP (r super(2) = 0.34), but not to either RQFlex-DP or MRP. Relationships between suspensions' EC and DP or TP were non-significant. Therefore, the RQFlex method is the only viable option for on-site quick estimates of DP that can be made more robust when complemented with TS and pH measurements. The DP quick test can provide near real-time information on soluble manure nutrient content across a wide range of handling and storage conditions on dairy farms and quick estimates of potential soluble P losses in runoff following land applications of manure.

A soda-lime technique was used to measure soil carbon dioxide (CO2) efflux rates in clearcut plots of a Missouri oak-hickory (Quercus spp. L.-Carya spp. Nutt.) forest 4 years after being treated with two levels of forest biomass removal and two levels of compaction, both separate and in combinations, and an uncut control. Respiration rates were measured twice a month from mid-April through October. Soil CO2 efflux rates were significantly (p<0.001) higher in uncut control plots than in clearcut plots, but differences between biomass removal or soil compaction treatments were not significant. Soil CO2 efflux rates were positively correlated with soil temperature. The lack of difference between soil CO2 efflux rates in weed control and no weed control subplots suggests that several more years may be required for regenerating clearcut plots to produce soil respiration rates similar to those in uncut control plots.

Disease outbreaks related to freshwater exposure have been documented, but the presence of these organisms in the urban aquatic environment is not well characterized. From April 2002 through April 2004 we conducted weekly surveys of streams in the metropolitan Baltimore, Md., area for the prevalence of potentially pathogenic E. coli by using PCR assays targeting the tir and stx sub(1) and stx sub(2) genes. Coliforms testing positive for the presence of the tir gene were cultured from 653 of 1,218 samples (53%), with a greater prevalence associated with urban, polluted streams than in suburban and forested watershed streams. Polluted urban streams were also more likely to test positive for the presence of one of the stx genes. Sequence analysis of the tir amplicon, as well as the entire tir gene from three isolates, indicated that the pathogenic E. coli present in the stream waters has a high degree of sequence homology with the E. coli O157:H7 serotype. Our data indicate that pathogenic E. coli are continually deposited into a variety of stream habitats and suggest that this organism may be a permanent member of the gastrointestinal microflora of humans and animals in the metropolitan Baltimore area.

Since 1993, millions of dollars of new development have poured into the flood-impacted areas contrary to the recommendations of Interagency Floodplain Management Review Committee, among others. Tracking development has been difficult. A diverse set of regulations and land use controls have caused varying amounts of development in the Upper Mississippi River Basin, with Missouri leading the way with over 17.31 km super(2) of new development. This study documents the changes in the basin affected by the 1993 floods 10 years after the event by conducting an analysis to identify new development within the 500-year floodplain and in the floodwater inundated areas. This study used Landsat satellite data to identify areas experiencing development.

Juniper removal has accelerated during the past decade in Oregon and California to restore shrub-steppe plant communities. Livestock grazing can affect posttreatment successional dynamics, but these impacts have not received adequate study. This study evaluated herbaceous plant recovery in a cut western juniper woodland subjected to grazed and ungrazed prescriptions over 4 growing seasons. The study consisted of 4 treatments: ungrazed cut, grazed cut, ungrazed woodland, and grazed woodland. Stocking rates were 0.78 cow-calf pairs per ha for 5 days in the first year following treatment and 0.94 cow-calf pairs per ha for 4 days in the second year after treatment. The grazing portion of the study lacked true replication because grazed plots were not independent of each other (cattle had access to all plots simultaneously). This limits the strength and interpretation of the grazing results. Juniper cutting removed overstory interference and resulted in significant increases in herbaceous cover, biomass, and seed production when compared to adjacent woodlands. Herbaceous cover, standing crop, perennial grass density, and seed production all increased in the ungrazed cut treatment compared to ungrazed woodland. A similar level of response was measured in the grazed pasture where herbaceous responses were greater in the grazed cut vs. the grazed woodland. Grazing in the cut treatment did not limit herbaceous recovery except that perennial grass seed production was lower in the grazed cut than in the ungrazed cut. Rest or deferment is required the first several growing seasons after juniper cutting to provide plants the opportunity to maximize seed crops. These results imply that juniper cutting had a greater effect on herbaceous dynamics than did the grazing application.

We addressed the occurrence of spawning in the study area and 2 potential impacts of cattle behavior during chinook salmon spawning: 1) disruption of spawning behavior by the presence of cattle near the redd and 2) the frequency of actual cattle contact with redds. Frequency of salmon redds was not significantly different in the stream reaches accessible to cattle compared with excluded reaches. Salmon continued preexisting patterns of behavior while cattle were within visible range of a redd. Cattle were seldom close to a redd and the chance for direct interaction to occur was minimal. When cattle were visibly near the active redd, cattle remained greater than 3.0 m from the active redd 84% of the time. Of the total time redds were observed, cattle contacted the redds <0.01% of the time. Previous studies have shown salmon that are harassed during spawning can retain eggs and even go completely unspawned. All salmon fully spawned in the study area in both years of the study.

Water-extractable phosphorus (WEP) concentrations in runoff from these fields are above the EPA drinking water limit of 0.1mgkg-1. Runoff studies have been conducted on poultry litter-amended soils to determine the effect of aluminum (Al) on WEP and iron oxide-adsorbable phosphorus (FeO-P). The drinking water treatment residue (DWTR) used in this experiment is an Al-rich-byproduct that is produced during drinking water purification. The objective of this study was to evaluate the ability of DWTR to reduce WEP and FeO-P concentrations in runoff from poultry litter by using a laboratory rainfall simulator. Poultry litter was collected from three poultry farms on Maryland Eastern Shore, air dried and crushed to less than 2mm, treated with DWTR at rates of 0, 50, and 100gkg-1 (dry weight basis), and incubated for 2 weeks at 25DGC. Water-extractable P and FeO-P in the runoff decreased with increase DWTR application. The total P released in runoff from the 50 and 100gkg-1 DWTR treatments were 79% and 91% lower than the no-DWTR treatment, respectively. There was a strong correlation between WEP and FeO-P in the runoff samples. The results of this study demonstrated that the addition of DWTR to poultry litter effectively reduced phosphorus in runoff.

In the course of a survey of 33 different bacterial isolates, we have identified, using a phenotypic assay for rhamnolipid production, a strain of the nonpathogenic bacterial species Pseudomonas chlororaphis that is capable of producing rhamnolipids. Rhamnolipid production by P. chlororaphis was achieved by growth at room temperature in static cultures of a mineral salts medium containing 2% glucose. We obtained yields of roughly 1 g/liter of rhamnolipids, an amount comparable to the production levels reported in Pseudomonas aeruginosa grown with glucose as the carbon source. The rhamnolipids produced by P. chlororaphis appear to be exclusively the mono-rhamnolipid form. The most prevalent molecular species had one monounsaturated hydroxy fatty acid of 12 carbons and one saturated hydroxy fatty acid of 10 carbons. P. chlororaphis, a nonpathogenic saprophyte of the soil, is currently employed as a biocontrol agent against certain types of plant fungal diseases. The pathogenic nature of all bacteria previously known to produce rhamnolipids has been a major obstacle to commercial production of rhamnolipids. The use of P. chlororaphis therefore greatly simplifies this matter by removing the need for containment systems and stringent separation processes in the production of rhamnolipids.

Breeding resistant cultivars would be an effective approach to reduce aflatoxin accumulation. The objective of this study was to investigate the expression of the pathogenesis-related (PR) protein beta -1,3-glucanase and the isoform patterns in peanut seed inoculated with A. flavus. Peanut genotypes GT-YY9 and GT-YY20 (both resistant to A. flavus infection) and Georgia Green and A 100 (both susceptible to A. flavus infection) were used in this study. The activities of beta -l,3-glucanase were similar in the uninfected seed of all genotypes, but increased significantly in the resistant genotypes after inoculation in comparison with the susceptible genotypes. An in-gel (native polyacrylamide gel electrophoresis [PAGE]) enzymatic activity assay of beta -1,3-glucanase revealed that there were more protein bands corresponding to beta -1,3-glucanase isoforms in the infected seed of resistant genotypes than in the infected seed of susceptible genotypes. Both acidic and basic beta -1,3-glucanase isoforms were detected in the isoelectric focusing gels. Thin-layer chromatography analysis of the hydrolytic products from the reaction mixtures of the substrate with the total protein extract or individual band of native PAGE revealed the presence of enzymatic hydrolytic oligomer products. The individual bands corresponding to the bands of beta -1,3-glucanase isoforms Glu 1 to 5 were separated on the sodium dodecyl sulfate-PAGE, resulting in two bands of 10 and 13 kDa, respectively. The sequences of fragments of the 13-kDa major protein band showed a high degree of homology to conglutin, a storage protein in peanut seed. Conglutin is reported as a peanut allergen, Ara h2. Our data provide the first evidences for peanut having beta -1,3-glucanase activities and the association with the resistance to A. flavus colonization in peanut seed. We have not directly demonstrated that conglutin has beta -1,3-glucanase activity.

A segregating F sub(2) population was derived from the cross between pinto bean breeding line P94207-189A (bc-1 bc-1 I I) and Olathe (bc-1 super(2) bc-1 super(2) i i). Real-time PCR assays were developed that were specific for each allele, and a multiplex PCR reaction could unambiguously assign F sub(2) plants to one of nine genotypes. Remnant F sub(1) plants were used as a comparative reference sample. PCR results among this sample fit a normal distribution for both real-time PCR assays, and 99% probability distributions were determined for heterozygotes. F sub(2) plants were genotyped based on results relative to the probability distributions for heterozygotes. F sub(2) plants also were genotyped for the I and bc-1 super(2) alleles by performing F sub(3) family progeny tests for virus resistance. Agreement between the two methods was 100% (198/198) for the bc-1 super(2) allele, and 92.4% (183/198) for the I allele. Erroneous genotyping was due to recombination between the amplicon and the I allele. Real-time PCR assays provide a robust method for genotyping seedlings and, in some cases, may eliminate the need for progeny testing.

Roem. & Schult), a member of the family Apocynaceae, is characterized by fleshy stems and leaves and colorful flowers. This exotic ornamental, originally from southeast Africa, is propagated vegetatively and is a perennial in warm climates. Virus-like foliar symptoms, including chlorotic ring and line patterns, were observed in the fall of 2004 on one of five stock plants being maintained in a greenhouse in Fort Pierce, FL. Inclusion body morphology suggested the presence of a Tospovirus in the symptomatic plant, and Tomato spotted wilt virus (TSWV) was specifically identified in this plant using a commercially available double antibody sandwich-enzyme linked immunosorbent assay (DAS-ELISA; Agdia, Elkhart, IN). TSWV was not detected in symptomless desert rose plants nor was Impatiens necrotic spot virus detected in any of the plants using DAS-ELISA. Graft transmission of TSWV to other desert rose plants was successful. Sequence analysis of a nucleocapsid (N) protein gene fragment amplified by reverse transcription-polymerase chain reaction (RT-PCR) with primers TSWV723 and TSWV722 from total RNA of the symptomatic plant confirmed the diagnosis. Nucleotide and deduced amino acid sequences of a 579-bp region of the RT-PCR product were 95 to 99% and 95 to 100% identical, respectively, to TSWV N-gene sequences in GenBank. No product was amplified from symptomless plants. Since these 3-year-old plants were grown on-site from seed and only expressed symptoms 2 months following damage to the greenhouse by hurricanes Frances and Jeanne, it is likely that viruliferous thrips were introduced from local vegetable or ornamental production areas during or following the storms. To our knowledge, this is the first report of TSWV infection of desert rose in Florida, although TSWV was observed in this plant in Europe approximately 10 years ago. Because of the wide distribution of TSWV in the United States, the increasing popularity of desert rose, and the recent identification of Cucumber mosaic virus in this host, attention to sanitation and insect vector management is merited during desert rose propagation and production.

The drencher required as little as 125 liters of the treatment solution and permitted various bin travel speeds. Wounded apples were placed midway between the bottom and top of the bin, in the center, and near the four corners of the bin (20 fruit per location) and covered with enough unwounded apples to fill the bin. The bins were drenched with a suspension containing Penicillium expansum at 2 x 10 super(4) conidia per ml in 2000, 5 x 10 super(3) conidia per ml in 2001, and 3 x 10 super(3) conidia per ml in 2002 and 2003. In 2000 and 2003, the additional treatments included a combination of P. expansum with the yeast Metschnikowia pulcherrima at similar to 1.2 x 10 super(7) CFU/ml, and in 2003 a combination with 2% sodium bicarbonate (SB) or a mixture of the yeast and SB. After 3 months of storage at similar to 2 degree C, at all P. expansum conidial concentrations, more than 90% of wounded fruit developed decay on `Golden Delicious', `Delicious', and `Rome' apples in the 2000-02 experiments. In 2003, 66 and 33.1% of the wounded fruit developed decay on `Delicious' and `Golden Delicious', respectively. The application of the antagonist reduced decay to 39 and 3.3% on `Golden Delicious' in 2000 and 2003, respectively, and to 26% on `Delicious' in 2003. The addition of SB reduced decay on both cultivars and, in combination with the yeast, was the most effective treatment on `Golden Delicious'. This portable drencher can be very useful for evaluating different treatments applied to apples after harvest at the commercial level.

During 2002-03, several sugar beet fields with cultivars partially resistant to BNYVV grown in the Imperial Valley of California were observed with severe rhizomania symptoms, suggesting that resistance conditioned by Rz1 had been compromised. Soil testing with sugar beet baiting plants followed by enzyme-linked immunosorbent assay (ELISA) was used to diagnose virus infection. Resistant varieties grown in BNYVV-infested soil from Salinas, CA, were ELISA-negative. In contrast, when grown in BNYVV-infested soil collected from the Imperial Valley, CA, all resistant varieties became infected and tested positive by ELISA. Based on host reaction, eight distinct BNYVV isolates have been identified from Imperial Valley soil (IV-BNYVV) by single local lesion isolation. Reverse transcription-polymerase chain reaction (RT-PCR) assays showed that the eight IV-BNYVV isolates did not contain RNA-5. Single-strand conformation polymorphism banding patterns for the IV-BNYVV isolates were identical to A-type and different from P-type. Sequence alignments of PCR products from BNYVV RNA-1 near the 3' end of IV-BNYVV isolates revealed that both IV-BNYVV and Salinas BNYVV isolates were similar to A-type and different from B-type. Our results suggest that the resistance-breaking BNYVV isolates from Imperial Valley likely evolved from existing A-type isolates.

Chlorotic spots, ranging from light green to yellow, appear on the middle leaves of the affected plants. Virions measuring 75 to 105 nm, similar in size to tospovirus particles, were present in crude extracts and ultrathin sections of diseased leaves. Of 35 plant species inoculated mechanically, 24, including wax gourd (Benincasa hispida) and zucchini squash (Cucurbita pepo), were susceptible to the virus. CCSV was transmitted from infected wax gourd by Thrips palmi to healthy wax gourd and zucchini squash. The virus was weakly related to Watermelon silver mottle virus (WSMoV) in enzyme-linked immunosorbent assay (ELISA) and western blot tests. WSMoV-specific N gene primers, however, failed to produce DNA fragments from total RNA extracts of CCSV-infected plants in reverse transcription-polymerase chain reaction (RT-PCR). Results of RT-PCR show that the conserved regions of the L genes of tospoviruses are present in CCSV.

There are many mechanisms for synchronizing developmental milestones, such as egg laying (oviposition), egg hatching, cocoon opening, and the emergence of adults. These are often irreversible, specific to particular life stages, and include diapause, an altered physiological state which can be reversed by some synchronizing environmental cue (e.g. photoperiod). However, many successful organisms display none of these mechanisms for maintaining adaptive seasonality. In this paper, we briefly review the mathematical relationship between environmental temperatures and developmental timing and discuss the consequences of viewing these models as circle maps from the cycle of yearly oviposition dates and temperatures to oviposition dates for subsequent generations. Of particular interest biologically are life cycles which are timed to complete in exactly 1 year, or univoltine cycles. Univoltinism, associated with reproductive success for many temperate species, is related to stable fixed points of the developmental circle map. Univoltine fixed points are stable and robust in broad temperature bands, but lose stability suddenly to maladaptive cycles at the edges of these bands. Adaptive seasonality may therefore break down with little warning with constantly increasing or decreasing temperature change, as in scenarios for global warming. These ideas are illustrated and explored in the context of Mountain Pine Beetle (Dendroctonus ponderosae Hopkins) occurring in the marginal thermal habitat of central Idaho's Rocky Mountains. Applications of these techniques have not been widely explored by the applied math community, but are likely to provide great insight into the response of biological systems to climate change.

A fractional factorial design was used to measure the effects and interactions of temperature (4-37 C), pH (2-6) and NaCl (0.5-9%) on survival kinetics of Shigella flexneri strain 5348 in BHI broth. Stationary-phase cells were inoculated into sterile media to give initial populations of 6-7 log sub(10) CFU/ml and bacterial populations were determined periodically by aerobic plate counts. A total of 267 cultures, representing 83 variable combinations of temperature, pH and NaCl concentration, were analyzed. Survivor curves were fitted from plate count data by means of a two-phase linear model to determine lag times and slopes of the curves, from which decimal reduction times (D-values) and times to a 4-log sub(10) inactivation (t sub(4D)) were calculated. Second order response surface models in terms of temperature, initial pH and NaCl concentration were obtained for the inactivation kinetics parameters of S. flexneri using regression analysis. The use of log sub(10) transformation of the inactivation kinetics parameters yielded models with R super(2) values of >0.8. These models can provide an estimate of Shigella inactivation. The data obtained suggest that Shigella is resistant to acid and salt and that low pH foods stored at low temperatures may serve as vehicles for gastrointestinal illness.

Ionizing radiation has been used to inactivate Salmonella on a variety of foods and contact surfaces, but the relative efficacy of the process against biofilm-associated cells versus free-living planktonic cells is not well documented. The radiation sensitivity of planktonic or biofilm-associated cells was determined for three food-borne-illness-associated isolates of Salmonella: Biofilms were formed on sterile glass slides in a coincubation apparatus, using inoculated tryptic soy broth, incubated at 37 degree C for 48 h. Resulting biofilms were 18 to 24 mu m in height as determined by confocal scanning laser microscopy. The planktonic and biofilm cultures were gamma irradiated to doses of 0.0 (control), 0.5, 1.0, 1.5, 2.0 and 2.5 kGy. The D sub(10) value (the dose of radiation required to reduce a population by 1 log sub(10), or 90%) was calculated for each isolate-culture based on surviving populations at each radiation dose. The D sub(10) values of S. enterica serovar Anatum were not significantly (P < 0.05) different for biofilm-associated (0.645 kGy) and planktonic (0.677 kGy) cells. In contrast, the biofilm-associated cells of S. enterica serovar Stanley were significantly more sensitive to ionizing radiation than the respective planktonic cells, with D sub(10) values of 0.531 and 0.591 kGy, respectively. D sub(10) values of S. enterica serovar Enteritidis were similarly reduced for biofilm-associated (0.436 kGy) versus planktonic (0.535 kGy) cells. The antimicrobial efficacy of ionizing radiation is therefore preserved or enhanced in treatment of biofilm-associated bacteria.

In studies of natural succession and invasion, however, the presence of late-successional vegetation is often confounded with lower weed propagule pressure and greater time since disturbance. This paper reports a study in which propagule pressure and time since disturbance were controlled by adding weed species to experimental plots dominated by early and late- successional perennial grass species. Seeds of 12 weed species were added to randomized, 6-year-old plots of restored prairie and non-restored, old-field vegetation. Restoration reduced added weed biomass by 92% in year one and 72% in year two, and reduced biomass of four individual weed species, each by more than 82%. Likely mechanisms through which restoration may have reduced invasion include competition and establishment limitation. To examine these mechanisms, subplots were treated with N addition and burning, to reduce competition and remove litter, respectively. Several patterns suggest that competition may have mediated reductions in weed invasion: restoration increased biomass of resident vegetation, decreased light levels, and decreased weed size. Furthermore, adding N reduced effects of restoration on resident and added weeds. The importance of establishment limitation in reducing invasion is suggested by increased litter mass and decreased weed density with restoration. Burning removed litter, and reduced effects of restoration on added weeds. These results suggest that tallgrass prairie restoration can reduce weed invasion, and that this reduction may involve multiple mechanisms, including competition and establishment limitation.

Several antibodies were developed for the polybrominated diphenyl ether flame retardant BDE-47 (1), often found in the highest concentration in human milk, plasma, and adipose tissue. Four haptens with different bromine and linker substitution patterns were synthesized and utilized to generate five polyclonal antibodies from goats and two polyclonal antibodies from rabbits. Competition was assessed using four different coating antigens for all seven antibodies. The coating antigen showed marked effects on competition. When the same hapten was used for antibody and the coating antigen less competition was observed. The effect of BDE structure on competition was evaluated by using BDE-47 (1), BDE-99 (2), BDE-100 (3), BDE-153 (4), and BDE-183 (5). None of the compounds showed high competition with antibody I-KLH, presumably because steric hindrance prevented formation of an efficient binding site. As predicted from structural considerations, BDE-47 (1) competed well with the remaining antibodies, whereas BDE-100 (3) competed well with only II-KLH. The remaining congeners (BDE-99 (2), BDE-153 (4), and BDE-183 (5)) contain bromines that cannot be positioned in binding sites and thus cross-react poorly. The competition study demonstrated that a bromine substitution on the congener could occupy a position analogous to the linker's position.

In this paper we present an approach to analyzing the patterns of autocorrelation in animal movements that provides a detailed picture of seasonal variability in the scale and patterns of movement. We used a combination of moving window Mantel correlograms, surface correlation and cross-correlation analysis to investigate the scales and patterns of autocorrelation in the movements of three herds of elephants in northern Botswana. Patterns of autocorrelation of elephant movements were long-range, temporally complicated, seasonally variable, and closely linked with the onset of rainfall events. Specifically, for the three elephant herds monitored there was often significant autocorrelation among locations up to lags of 30 days or more. During many seasonal periods there was no indication of decreasing autocorrelation with increasing time between locations. Over the course of the year, herds showed highly variable and complex patterns of autocorrelation, ranging from random use of temporary home ranges, periodic use of focal areas, and directional migration. Even though the patterns of autocorrelation were variable in time and quite complex, there were highly significant correlations among the autocorrelation patterns of the different herds, indicating that they exhibited similar patterns of movement through the year. These major patterns of autocorrelation seem to be related to patterns of rainfall. The strength of correlation in movement patterns of the different herds decreased markedly at the cessation of major rain events. Also, there was a strong cross-correlation between strength of autocorrelation of movement and rainfall, peaking at time lags of between three and four weeks. Overall, these approaches provide a powerful way to explore the scales and patterns of autocorrelation of animal movements, and to explicitly link those patterns to temporally variable environmental attributes, such as rainfall or vegetation phenology.

This review highlights major milestones in its evolution and presents a perspective on its current direction. Fungal pathogens, the most eye-catching agents, dominated the early period, but major mycological control efforts for chinch bugs and citrus pests in the US had questionable success, and interest waned. The discoveries of Bacillus popilliae and Bacillus thuringiensis began the era of practical and commercially viable microbial control. A program to control the Japanese beetle in the US led to the discovery of both B. popilliae and Steinernema glaseri, the first nematode used as a microbial control agent. Viral insect control became practical in the latter half of the 20th century, and the first registration was obtained with the Heliothis nuclear polyhedrosis virus in 1975. Now strategies are shifting for microbial control. While Bt transgenic crops are now planted on millions of hectares, the successes of more narrowly defined microbial control are mainly in small niches. Commercial enthusiasm for traditional microbial control agents has been unsteady in recent years. The prospects of microbial insecticide use on vast areas of major crops are now viewed more realistically. Regulatory constraints, activist resistance, benign and efficacious chemicals, and limited research funding all drive changes in focus. Emphasis is shifting to monitoring, conservation, integration with chemical pesticides, and selection of favorable venues such as organic agriculture and countries that have low costs, mild regulatory climates, modest chemical inputs, and small scale farming.

This study demonstrates protection from simulated solar radiation by coating B. bassiana (GHA) spores with lignin and effects on pathogenicity to Lygus lineolaris (Palisot de Beauvois) adults in direct spray and contact uptake bioassays. Spores were coated with either lignin or cross-linked lignin by spray drying to produce spore coatings of high and low water solubility, respectively. Non-coated spores and the two spore coating treatments were suspended in either water (0.04% Silwet L77) or oil (Orchex 692) to produce six formulations. Rates of loss in spore viability under simulated solar radiation were approximately ten times lower for the three formulations in which spores remained coated in suspension (cross-linked lignin in water, cross-linked lignin in oil, and lignin in oil). However, these three formulations were the least pathogenic. Estimates of LC sub(50) and LC sub(75) values for the most pathogenic formulation (non-coated in oil) were 5 and 12 times lower, respectively, than the least pathogenic formulation (cross-linked lignin in oil), but these differences were not significant. The three lignin-coated formulations that provided the greatest UV protection were also the least pathogenic based on LT values, which were significant. Overall, L. lineolaris mortality was approximately 80 times less when exposed to treated broccoli rather than sprayed directly, based on LC sub(50) values. If the contribution of spore uptake from plant surfaces to L. lineolaris mortality is similarly low under field conditions, then improving persistence may be less important for improving efficacy. However, under control conditions where solar radiation significantly impacts mycoinsecticide efficacy, the improved persistence of lignin coating formulations may outweigh negative effects on pathogenicity.

Various modifications of existing methods have been proposed to speed up the different steps involved in plant transformation, as well as a few add-on technologies that seek to address issues related to biosafety or intellectual property. The problem with an assortment of independently developed improvements is that they do not integrate seamlessly into a single transformation system. This paper presents an integrated strategy for plant transformation, where the introduced DNA will be inserted precisely into the genome, the transgenic locus will be introgressed rapidly into field varieties, the extraneous transgenic DNA will be removed, the transgenic plants will be molecularly tagged, and the transgenic locus may be excised from pollen and/or seed.

Tarajuilie tea from India, cocoa powder, and cocoa nibs contained the highest levels of methylxanthines. Theobromine, caffeine, and theophylline combined in the ratios observed in tea and chocolate were ingested by coyotes. Although both mixtures induced acute toxicity, the symptoms accompanying the chocolate methylxanthine mimic were preferable. Manipulation of the ratios of methylxanthines in the chocolate mimic led to the identification of a 5:1 theobromine/caffeine mixture as a promising coyote toxicant. This mixture was then administered to coyotes using the coyote lure operative device (CLOD). Mortality occurred in every coyote that ingested any portion of the CLOD contents. These results indicate that mixtures of theobromine and caffeine have the potential to be developed into a selective, effective, and socially acceptable toxicant for the control of pest coyotes.

The hypothesis that respiration of leaves of soybeans grown at elevated [CO sub(2)] is increased is tested; and the effects of photosynthesis and acclimation to temperature examined. times METHODS: Net rates of carbon dioxide exchange were recorded every 10 min, 24 h per day for mature upper canopy leaves of soybeans grown in field plots at the current ambient [CO sub(2)] and at ambient plus 350 mu mol mol super(-1) [CO sub(2)] in open top chambers. Measurements were made on pairs of leaves from both [CO sub(2)] treatments on a total of 16 d during the middle of the growing seasons of two years. times Key Results Elevated [CO sub(2)] increased daytime net carbon dioxide fixation rates per unit of leaf area by an average of 48 %, but had no effect on night-time respiration expressed per unit of area, which averaged 53 mmol m super(-2) d super(-1) (1.4 mu mol m super(-2) s super(-1)) for both the ambient and elevated [CO sub(2)] treatments. Leaf dry mass per unit of area was increased on average by 23 % by elevated [CO sub(2)], and respiration per unit of mass was significantly lower at elevated [CO sub(2)]. Respiration increased by a factor of 2.5 between 18 and 26 degree C average night temperature, for both [CO sub(2)] treatments. times CONCLUSIONS: These results do not support predictions that elevated [CO sub(2)] would increase respiration per unit of area by increasing photosynthesis or by increasing leaf mass per unit of area, nor the idea that acclimation of respiration to temperature would be rapid enough to make dark respiration insensitive to variation in temperature between nights.

A crystal violet binding assay demonstrated no significant differences in biofilm formation by isolates from any source when tested in any of the following three media: Luria- Bertani broth supplemented with 2% glucose, tryptic soy broth (TSB), or 1/20th- strength TSB. Incubation was overnight at 30 degree C under static conditions. Curli production and cellulose production were monitored by assessing morphotypes on Luria-Bertani agar without salt containing Congo red and by assessing fluorescence on Luria-Bertani agar containing calcofluor, respectively. One hundred percent of the clinical isolates exhibited curli biosynthesis, and 73% demonstrated cellulose production. All meat-related isolates formed curli, and 84% produced cellulose. A total of 80% of produce-related isolates produced curli, but only 52% produced cellulose. Crystal violet binding was not statistically different between isolates representing the three morphotypes when grown in TSB; however, significant differences were observed when strains were cultured in the two other media tested. These data demonstrate that the ability to form biofilms is not dependent on the source of the test isolate and suggest a relationship between crystal violet binding and morphotype, with curli-and cellulose-deficient isolates being least effective in biofilm formation.

To better understand how burning influences the cycling of N in prairie, super(15)N was injected to soil as NH sub(4) super(+), and the partitioning between plant and soil N pools was followed over five growing seasons in annually burned and unburned prairie. Applied super(15)N was rapidly immobilized with <2% and 11% of the super(15)N remaining in inorganic forms six days after application in burned and unburned prairie, respectively. Seventy-seven percent (burned prairie) and 70% (unburned prairie) of the applied super(15)N was initially recovered as soil organic N (oN), with a majority accounted for in microbial biomass. Plants contained similar to 20% of the applied N with the largest portion recovered from roots regardless of burning. At the end of the first growing season, only 55% of the applied super(15)N was recovered from the unburned prairie, while 85% was recovered from burned prairie. The total super(15)N content of the plants changed little during the first growing season, but the portion recovered in the rhizomes increased, indicating belowground N storage. Total recovery and distribution of applied N changed little from the end of the first to the end of the second season growing season. Accumulations of super(15)N within the plants decreased greatly between the second and fifth growing seasons, but N lost from plants was accounted for in oN. Conservation of N by plants and tight cycling of N within the root zone suggest mechanisms by which prairie can be a highly productive ecosystem despite limited N availability. The immobilization of potentially mineralized N within the root zone increased with burning, offsetting the loss of N to fire probably by reducing leaching and denitrification losses.

CO sub(2) enrichment substantially enhanced both above- and belowground growth variables of both varieties for all harvest dates (8, 16, and 24 days postemergence). This growth enhancement was greater for aboveground variables (21%-35%) at the first harvest, greater for belowground variables (36%-40%) at the second harvest, and similar for both above- (13%-68%) and belowground (10%-40%) variables at the last harvest. Differences in temporal growth enhancement associated with CO sub(2) enrichment suggest changing carbon allocation priorities, with initial carbon investment allocated primarily aboveground to develop photosynthetic machinery, and later carbon allocations predominately directed toward increased investment in roots. The absence of significant CO sub(2) x variety interactions at any harvest date provides evidence that CO sub(2) enrichment did not exaggerate growth responses between the 2 varieties. These results suggest that varietal differences in rooting and other characteristics did not modify the size advantage of the glandulosa over the torreyana variety, as the absolute differences in sizes did not change as a function of CO sub(2) treatment. Although CO sub(2) enrichment did not exaggerate growth differences between varieties in this species, it is evident that honey mesquite seedlings possess the capacity to respond markedly to CO sub(2) enrichment. The greater root depth of honey mesquite seedlings exposed to CO sub(2) enrichment confers a competitive advantage to mesquite seedlings over grass seedlings, assuming that C sub(3) and C sub(4) grass seedlings will not respond as vigorously to CO sub(2) enrichment. As such, this species should continue to aggressively encroach into grasslands in future CO sub(2)-enriched environments.Original Abstract: Plantulas de dos variedades de 'Mesquite' (Prosopis glandulosa var. glandulosa y P. glandulosa var. torreyana) fueron expuestas a dos concentraciones de CO sub(2)(368 y 704 mu mol . mol super(-1)) en invernaderos con ambiente controlado bajo condiciones de temperatura y humedad en suelo cercanas al optimo a fin de determinar si el enriquecimiento de CO sub(2) altera la respuesta del crecimiento aereo y radicular. El enriquecimiento de CO sub(2) mejoro sustancialmente las variables del crecimiento tanto aereo como radicular en ambas variedades en todas las fechas de cosecha (8, 16, y 24 dias a la postemergencia). El estimulo al crecimiento fue mayor para variables de crecimiento aereo (21%-35%) en el primer corte, mayor para variables de crecimiento radicular (36%-40%) en el segundo corte y similar para ambos aereo (13%-68%) y radicular (10%-40%) en el ultimo corte. Las diferencias en la mejoria temporal del crecimiento asociadas al enriquecimiento de CO sub(2) sugieren un cambio en las prioridades de ubicacion del carbon, con inversiones iniciales de carbon asignadas principalmente al a la parte aerea a fin de desarrollar la maquinaria fotosintetica y translocacion posterior de carbon para el crecimiento de raices. La ausencia de interacciones significativas de CO sub(2)X variedad en cualquier fecha de cosecha provee evidencia de que el enriquecimiento de CO sub(2) no estimula exageradamente la respuesta al crecimiento entre las dos variedades. Los resultados sugieren que las diferencias varietales en raices y otras caracteristicas no modifican la ventaja del tamano de la glandulosa sobre la torreyana, las diferencias absolutas en tamano no cambian en funcion de los tratamientos de CO sub(2). Aunque el enriquecimiento de CO sub(2) no magnifico las diferencia de crecimiento entre variedades de esta especie, es evidente que las plantulas de 'Mesquite' poseen la capacidad de responder marcadamente al enriquecimiento de CO sub(2.)La mayor profundidad de raices de plantulas de mesquite expuestas al enriquecimiento de CO sub(2)le confiere una ventaja competitiva sobre plantulas de zacates , asumiendo que las plantulas de zacates C sub(3) y C sub(4), no responderan tan vigorosamente al enriquecimiento de CO sub(2). Por lo tanto, en el futuro, esta especie continuara expandiendose agresivamente hacia los pastizales en ambientes enriquecidos con CO sub(2).

The active salmon redds accessible to cattle were at a density of 4.6 redds per km in 1996 and 6.1 redds per km in 1997. The stocking rate was maintained at 0.82 ha.AUM super(-1) for 28 days. Cattle spent approximately 94% of their time in the terrestrial habitats (meadow, disturbance, low shrub, tall shrub, and trees) that supported herbivory-type activities (travel, graze, and rest), the remaining time was spent in stream habitats, which consisted of gravel bar (5%) and in aquatic (< 1%) habitats. Cattle spent approximately 88% of their time on nonherbivory-type activities while in the aquatic habitat. Individual cows were observed during the daylight hours for 18 of 28 days each year they were in the pasture and were never observed in direct contact with a redd. Cattle spent over half of their time drinking and < 0.01% of their time defecating while they were in the aquatic habitat. Defecation was proportional to time spent in each habitat; so about 2% of the manure was directly deposited in the stream.Original Abstract: Este estudio de dos anos se diseno para cuantificar la influencia de los habitats terrestres y de corrientes de agua en la distribucion y comportamiento del ganado en praderas riberenas con acceso a areas activas de ovoposicion (nidos) del 'Chinook salmon' (Oncorhynchus tshawytscha). Los nidos del salmon accesibles al ganado tenian una densidad de 4.6 sitios por kilometro en 1996 y 6.1 sitios por kilometro en 1997. La carga animal se mantuvo en 0.82 UAM super(-1) por 28 dias. El ganado paso aproximadamente el 94% de su tiempo en los habitats terrestres (pradera, sitios disturbados, arbustos bajos, arbustos altos y arboles) que sostuvieron las actividades del herbivoria (apacentar, descansar y viajar), el tiempo restante fue consumido en los habitats de corrientes de agua los cuales consistieron en bancos de grava (5%) y habitats acuaticos (< 1%). Cuando el ganado se encontraba en los habitats acuaticos aproximadamente dedico 88% de su tiempo a actividades diferentes a la herbivoria. En cada ano del estudio en18 de los 28 dias del periodo experimental se observaron vacas individuales durante las horas diurnas, ellas estuvieron en el potrero y nunca se observaron en contacto directo con los nidos del salomon. Cuando el ganado estaba en habitats acuaticos uso mas de la mitad de su tiempo tomando agua y < 0.01% de su tiempo defecando. La defecacion fue proporcional al tiempo que paso en cada habitat, de tal forma que aproximadamente el 2% del estiercol se deposito directamente en la corriente de agua.

H. hampei samples (n = 101) from 17 countries on three continents were examined. Only 26 unique fingerprints (haplotypes) were discovered among all samples. Genetic variability was extremely low (10% average polymorphism per sample), but genetic differentiation was high ( Phi sub(ST) = 0.464). The distribution of the fingerprints and their genetic relatedness to each other suggested that a West African source population invaded both Asia and America. Three distinct lines entered the Americas through either separate introductions or a single introduction of multiple lines. At least two were first introduced to Brazil and subsequently dispersed throughout the Americas. The third was discovered only in Peru and Colombia. Observations were consistent with the high rate of inbreeding suspected of this pest. With such high inbreeding, undesirable mutations, such as those conferring insecticide resistance, might rapidly become homozygous in H. hampei. However, the low genetic variability observed also suggests that this pest may lack the genetic variability necessary to respond to an intensive control strategy.Original Abstract: La tecnica AFLP fue usada para generar huella dactilares geneticas examinando la variacion genetica y la biogeografia de la plaga mas importante del cultivo del cafe, Coffea arabica L., la broca del cafe Hypothenemus hampei (Ferrari). Muestras de H. hampei (n = 101) provenientes de 17 paises en tres continentes fueron examinadas. Solo 26 huellas dactilares (haplotipos) fueron descubiertas. La variacion genetica fue extremadamente baja (10% promedio de polimorfismos por muestra), pero la diferenciacion genetica fue alta ( Phi sub(ST) = 0.464). La distribucion de las huellas dactilares y la relacion genetica entre ellas sugirieron que una poblacion originaria del Oeste de Africa que debio haber invadido tanto Asia como America. Tres lineas geneticas distintas entraron a las Americas, ya sea a traves de la introduccion independiente de varias lineas o a la introduccion unica de lineas multiples. Al menos dos lineas fueron inicialmente introducidas al Brasil y posteriormente se dispersaron por todas las Americas. La tercera linea fue decubierto solo en Peru y Colombia. Estas observaciones fueron consistentes con la alta tasa de endogamia con la que se sospecha que este insecto posee. Si esto es cierto, algunas mutaciones no deseadas, asi como aquellas que confieren resistencia a insecticidas, podrian volverse homozigoticas rapidamente. Sin embargo, la baja variacion genetica observada tambien podria estar sugiriendo que esta plaga carece de la variacion genetica necesaria para responder a una estrategia de control intensiva.

Nymphs and adults were individually reared on excised cowpea, Vigna unguiculata L. Walp., plants maintained in floral aquapics containing a hydroponic solution. Embryonic development of eggs was completed in 7.1 plus or minus 0.8 d with 92.6% of the incubated eggs hatching. Nymphs molted five times, and the nymphal period of 61 plus or minus 2.9 d for females was 1.2-fold significantly longer than that of males. The second nymphal stage was the shortest for both sexes (6.1 plus or minus 0.5 d for females and 5.8 plus or minus 0.8 d for males), whereas the last instar was the longest for females only. Stage-specific mortality was similar between instars; approximately 36% of the nymphs molted to adults. H. coagulata adult sex ratio was not significantly different from a 1:1 ratio. Adult females lived 52 plus or minus 11 d, and females deposited an average of 194 plus or minus 35 eggs each. Analysis of life table statistics indicated that populations of H. coagulata increased at a rate of 1.045 per day and doubled within 15.6 d. The different H. coagulata growth stages were well described by body length, head capsule width, and hind tibia length; however, analysis of frequency distribution showed that head capsule width was the most suitable parameter for distinguishing the immature developmental stages of H. coagulata.

We assumed an overdispersed Poisson distribution for count data, with overdispersion attributed to observer variability, and used Poisson regression for analysis of population trends. Overdispersion had a large, negative effect on power. The number of sampling years also had an especially large effect on power. In all cases, 10 years of sampling were insufficient to detect a decline in abundance of 30% over 10 years. Increasing the sampling period to 20 years provided adequate power for 56% of breeding species at one site. The number of count stations needed for detecting trends for a given species depended primarily on observer variability. If observer variability was high, increasing the number of years and visits was a better approach than increasing the number of stations. Increasing the number of stations was most beneficial for species with low abundance or low observer variability. When the number of stations is limited by the size of the area, we recommend multiple visits to stations. For most species, multiple visits per year (six or more) for 15-20 years were needed to detect a 30% decreasing trend in 10 years with adequate power. We suggest potentially useful focal species for monitoring, such as keystone species like the Acorn Woodpecker (Melanerpes formicivorus).

The objectives of this article are to denote the methods developed for evaluating herbicide retention in VFS; ascertain the efficacy of VFS regarding abating herbicide runoff; identify parameters that affect herbicide retention in VFS; review the environmental fate of herbicides retained by VFS; and identify future research needs. The retention of herbicide runoff by VFS has been evaluated in natural rainfall, simulated rainfall, and simulated run-on experiments. Parameters affecting herbicide retention in VFS include width of VFS, area ratio, species established in the VFS, time after establishment of the VFS, antecedent moisture content, nominal herbicide inflow concentration, and herbicide properties. Generally, subsequent transport of herbicides retained by VFS is reduced relative to adjacent cultivated soil because of enhanced sorption and degradation in the former.

Soil water potential ([Delta] psi ) and volumetric water content ( theta ) were measured concurrently at 10 cm intervals to 1 m depth to create in situ soil water retention curves (SWRC) under drying conditions. Non-linear regression was used to fit SWRC specific to each depth and site. We also quantified root biomass, soil texture, and hydraulic redistribution (HR) of soil water by roots to identify factors affecting the seasonal dynamics of root water uptake and depletion from the soil profile. Soil theta measured at a particular [Delta] psi increased with soil depth, and was strongly dependent upon soil texture. For example, when [Delta] psi was-0.1 MPa, theta ranged from 13% at 20 cm to 35% at 100 cm for the OG-DF forest. Soil texture and bulk density accounted for 60-90% of the variation in the SWRC. As the summer drought progressed, water extraction shifted to the deeper layers, and recharge from HR approached 0.15 mm day super(-1) in the upper 60 cm for all sites. Total water use from the upper 2 m at all sites peaked between 1.5-2.5 mm day super(-1) in mid-July and then declined to 0.5-1.0 mm day super(-1) by the end of the dry season. Total fine root biomass in the upper 1 m was 0.77 kg m super(-2) (OG-PP), 1.08 kg m super(-2) (OG-DF) and 1.15 kg m super(-2) (Y-DF), with 40% (PP) to 60% (DF) of fine roots located in the upper 20 cm. However, the upper 20 cm only accounted for 20% of total water depletion from the upper 2 m at peak water uptake, declining to 4-6% later in the season, illustrating the contribution of deeper roots to water uptake. Nevertheless, daily water uptake from the entire 2 m profile was strongly dependent on water potential at 20 cm, indicating that fine roots in the upper soil may play an important role in regulating water uptake through hydraulic effects on stomatal conductance.

Storage of atmospheric CO sub(2) into stable organic carbon pools in the soil can sequester CO sub(2) while common crop production practices can produce CO sub(2), generate N sub(2)O, and decrease the soil sink for atmospheric CH sub(4). The overall balance between the net exchange of these gases constitutes the net global warming potential (GWP) of a crop production system. Trace gas flux and soil organic carbon (SOC) storage data from long-term studies, a rainfed site in Michigan that contrasts conventional tillage (CT) and no-till (NT) cropping, a rainfed site in northeastern Colorado that compares cropping systems in NT, and an irrigated site in Colorado that compares tillage and crop rotations, are used to estimate net GWP from crop production systems. Nitrous oxide emissions comprised 40-44% of the GWP from both rain-fed sites and contributed 16-33% of GWP in the irrigated system. The energy used for irrigation was the dominant GWP source in the irrigated system. Whether a system is a sink or source of CO sub(2), i.e. net GWP, was controlled by the rate of SOC storage in all sites. SOC accumulation in the surface 7.5 cm of both rainfed continuous cropping systems was approximately 1100 kg CO sub(2) equivalents ha super(-1) y super(-1). Carbon accrual rates were about three times higher in the irrigated system. The rainfed systems had been in NT for >10 years while the irrigated system had been converted to NT 3 years before the start of this study. It remains to be seen if the C accrual rates decline with time in the irrigated system or if N sub(2)O emission rates decline or increase with time after conversion to NT.

We assessed genetic variation among 225 mottled ducks and mallards using five microsatellite loci, and detected significant overall differences between these species within two geographic areas. We characterized hybridization in Florida, where mottled ducks are endemic and mallards are beginning to appear on the breeding grounds, and in South Carolina, where mottled ducks were introduced outside their native range. We used Bayesian genetic mixture analysis in an attempt to distinguish between these closely related species. In Florida, we detected two distinct genetic groups, and 10.9% of our samples from Florida mottled ducks were inferred to have been hybrids. In contrast only 3.4% of Florida mallards were inferred to have been hybrids, suggesting asymmetric hybridization. Populations from different geographic areas within Florida exhibited hybridization rates ranging from 0% to 24%. These data indicate a genetic component would be appropriate in actively managing interspecific hybridization in Florida mottled ducks. In contrast, South Carolina mottled ducks and mallards cannot be differentiated.

While recent studies consider the spatial structure of ectomycorrhizal communities, few studies consider how this changes over time. Ectomycorrhizal root biomass and the similarity of community composition were measured at scales up to 20 cm replicated in nine plots and over 3 yr. Soil cores were additionally stratified into three depths. Annual occurrence of the dominant ectomycorrhizal species was constant at larger spatial scales but varied more across years at a fine spatial scale. Turnover of ectomycorrhizal species between years was observed frequently at scales < 20 cm. The ectomycorrhizal community within a plot was more similar across years than it was to other plots sampled in the same year. Our results demonstrate the dynamic nature of the ectomycorrhizal community even in the absence of large-scale disturbances. The potential role of root turnover and drought stress is discussed.

Only high concentrations were attractive in laboratory wind-tunnel bioassays. Attraction of flies to grapefruit oil was not enhanced if they had previous experience with grapefruit. In citrus orchard experiments, undiluted grapefruit oil attracted Mexican fruit flies and enhanced attraction to traps baited with a synthetic food-odor lure emitting ammonia and other nitrogenous chemicals. This is the first demonstration of host fruit odor increasing attraction to another type of attractive blend in Mexican fruit fly. These results indicate differences in the way the flies respond to undiluted grapefruit oil compared with previously tested fruit odors.

The sampler is simple in design, easy to make, inexpensive and resistant to harsh weather conditions. The sampler has been calibrated against honeycomb denuder systems in ambient southern California air and in controlled HNO sub(3) exposures. It is more precise than the old open-face HNO sub(3) sampler. It can measure wide ranges of ambient HNO sub(2) and HNO sub(3) concentrations for extended periods of time and can be used for regional-scale monitoring of the pollutants.

Our objective was to evaluate soil and manure characteristics and application rates on P extractability in recently amended soils. Five soils of the U.S. southern High Plains were amended with beef cattle manures, composted beef manure, and inorganic fertilizers [Ca(H sub(2)PO sub(4)) sub(2) or KH sub(2)PO sub(4)] at five rates and incubated under controlled conditions. Mehlich 3-, Olsen (NaHCO sub(3))-, Texas A&M extractant (TAM)-, and water-extractable P were determined for the soils after selected incubation periods. Except for TAM and some water extractions, P extractability as a function of total P applied was linear (P < 0.001) for a wide range of application rates. Mehlich-3, NaHCO sub(3), and water P extraction efficiencies of KH sub(2)PO sub(4)-amended soils averaged 22, 34, and 115% greater (P [<] 0.036), respectively, than efficiencies of soils amended with manures except for the Texline (calcareous) loam and Pullman clay loam soils. Phosphorus extraction efficiencies decreased with time for KH sub(2)PO sub(4)-amended soils (P < 0.05) but remained stable or increased for manure-amended soils during the 8-wk incubation period. Across all soils and manure sources, changes in water-extractable P per unit increase in Mehlich 3-, NaHCO sub(3)-, and TAM-extractable P averaged 100, 85, and 125% greater, respectively, for inorganic as compared with manure-amended soils. These source- dependent relationships limit the use of agronomic soil extractants to make correct inferences about water-extractable P and dissolved P in runoff.

The objectives of this research were to characterize ferrihydrite (Fe sub(5)HO sub(8) super(.)4H sub(2)O) in terms of its ability to adsorb P from soil solutions and relate its P adsorptive capacity to several soil properties that influence P mobility. A naturally occurring ferrihydrite, collected as an Fe oxide sludge by-product from a water treatment facility, was equilibrated with soil samples at equivalent rates of 0, 0.34, 3.36, 16.80, and 33.60 Mg ha super(-1) for a 60-d period. Individual 2-g subsamples of each soil were then equilibrated with 0, 5, 10, 20, and 40 mg kg super(-1) P in 20 mL of 0.01 M CaCl sub(2) on a reciprocating shaker for 24 h. After 24 h, P in solution was measured by colorimetric methods, and designated as final P concentrations. The data indicated that the unamended soils with a pH of 7.0. The final P concentrations, averaged for all initial P concentrations and ferrihydrite rates, ranged from 0.09 to 4.63 mg kg super(-1), and were most highly correlated with pH (r = 0.844; P [<] 0.01), oxalate-extractable Fe (r = -0.699; P [<] 0.10), and dithionite-extractable Fe (r = -0.639; P [<] 0.10) contents of the unamended soils. In terms of individual soils, correlation coefficients (r) for final P concentrations versus ferrihydrite amendment rates indicated a statistically significant (P [<] 0.001) negative relationship at all initial P concentrations for most A horizons. The r values for the high Fe oxide content B horizon soils did not show a statistically significant response to ferrihydrite additions. The results indicate that P adsorption, in soils amended with ferrihydrite, will be greatest under acid pH conditions below the ferrihydrite zero point of charge (pH 5.77), and low incipient Fe oxide contents.

We showed that it cleaves the amino-terminal lysyl residue from des-Arg super(10)-kallidin to produce des-Arg super(9)-bradykinin, suggesting that it plays a role in virulence. A survey was conducted to determine the presence of this potential virulence-enhancing enzyme among twenty-three halotolerant human and fish pathogens from eleven species within the Vibrionaceae family, including V. vulnificus, V. parahaemolyticus, V. cholerae, Aeromonas hydrophila, and Plesiomonas shigelloides. In addition, fourteen species of non-Vibrionaceae pathogens were screened for LysAP activity. Cell lysates were partially purified by anion exchange chromatography and fractions were screened for LysAP and isomerase activities. PGI-LysAP activity was detected in chromatographic fractions from all the Vibrio species tested, but was not detected in any of the non-Vibrionaceae pathogens. Levels of isomerase and LysAP activity correlated (R super(2)=0.92) for nine strains of V. vulnificus. Since the Vibrionaceae represent an important family of human and fish pathogens, our identification of PGI-LysAP activity in a broad array of vibrios may lead to the development of improved analytical methods for their identification as well as interventions to reduce the high morbidity and mortality associated with some Vibrionaceae infections in clinical, veterinary, and aquaculture settings.

We examined the effects of (i) exchangeable sodium percentage (ESP, 1-20) and fast wetting (50 mm h super(-1)) and leaching with distilled water on the HC of 60 Israeli soils (7-70% clay); and (ii) wetting rate (2 or 50 mm h super(-1)), ESP and water salinity (distilled water or saline water, 2 dS m super(-1)) on the HC of 16 selected samples. Results of the first experiment showed that (i) steady state HC of medium- and fine-textured soils was lower than 2 cm h super(-1) already for nonsodic soils, and (ii) the adverse impact of sodicity on the HC strongly depended on soil texture. The second experiment revealed that in the loamy sand rate of wetting had no effect on the HC beyond that of sodicity and salinity. In the loam, sandy clay and clay soils a significant triple interaction among water quality, wetting rate and ESP in their effect on HC existed. In the absence of electrolytes, the impact of fast wetting (slaking) and swelling on the HC was most notable, mainly at the intermediate sodicity levels (ESP = 5-10). Use of saline water significantly reduced the impact of fast wetting and swelling on the HC. Our results suggested that combined effects of salinity, wetting rate, and sodicity on the HC were complex and should thus be considered simultaneously when estimating soil HC.

Tests were conducted over two growing seasons in two adjacent field sites in southeastern Missouri. At the end of the 2001 season, eastern cottonwood trees grown on the coated paper mulches had average heights (4.57-4.66m, 15.0-15.3ft), which were not significantly different from the control black polyethylene mulch (4.75m, 15.6ft). Tree heights were significantly less for uncoated paper mulch (4.45m, 14.6ft) or no mulch (3.90m, 12.8ft), presumably due to heavy weed growth around the trees. Uncoated paper mulch was extensively degraded after only about 4 weeks, while the coated paper persisted until the fall. Addition of ZnO to the oil coating delayed the onset of visible degradation, such as the formation of holes and tears, especially near the buried edge and above the drip tube. Similar results were seen for the 2002 study except that weed growth was not extensive so that tree heights for the mulched and bare plots were not significantly different. These results suggest that polymerized vegetable oil-coated paper mulches can function as effective mulches during the first year of tree growth, and thus, eliminate the need to use non-degradable polyethylene mulches.

Spatio-temporal variability in soil water was assessed over four fields in a two-year potato (Solanum tuberosum L.) and barley (Hordeum vulgare L.) rotation to determine the potato yield implications and the potential for precision water management based on a stable spatial pattern of soil water. A hammer-driven time domain reflectometry probe was used to measure soil water content repeatedly along 10 transects. Irrigated, un-irrigated, and late irrigated treatments were employed. The temporally stable soil water pattern was mapped and compared with elevation and soil particle size classifications. A temporal stability model explained 47% of the observed variability in soil water content. An additional 20% of the variability was attributed to random measurement error. Calibrated in 2002, the model predicted water content (root mean square error of 0.05m super(3)m super(-) super(3)) along transects in 2003 from a single measurement at the field edge. Field-scale trends and extended (>100m) wet and dry segments were observed along transects. Coarser particle size class soils were generally drier. Potato yield increased linearly with water content in un-irrigated areas. Yield was comparatively high in the drier areas for the irrigated treatment but was highly variable and frequently poor in the wetter areas. For the late-irrigated treatment, a strong yield response to added water was evident in the dry areas; however, the yield response was neutral to negative in the wetter areas. Knowledge of the underlying stable soil water distribution could provide a useful basis for precision water management.

AN - 68430097; 16054985 AB - Epidemiologic observations implicate excess ethanol ingestion as well as low dietary folate intake as risk factors for several cancers. Moreover, the epidemiologic observations support the concept of a synergistic effect between these two factors. Such a relation is biologically plausible because ethanol impedes the bioavailability of dietary folate and is known to inhibit select folate-dependent biochemical reactions. For example, alcohol ingestion in animals is known to inhibit folate-mediated methionine synthesis and thereby may interrupt critical methylation processes that are mediated by the activated form of methionine that provides substrate for biologic methylation, S-adenosylmethionine. Consistent with this observed inhibition of methionine synthesis is the observation that chronic alcohol ingestion in laboratory animals is known to produce hypomethylation of DNA in the colonic mucosa, a constant feature of early colorectal neoplasia. Inhibition of methionine synthase also creates a "methylfolate trap," analogous to what occurs in vitamin B12 deficiency. In addition, some evidence indicates that alcohol may redirect the utilization of folate toward serine synthesis and thereby may interfere with a critical function of methylenetetrahydrofolate, thymidine synthesis. Although a mechanistic link between alcohol and impaired folate metabolism in the genesis of cancer is still not definitively established, such a link should be pursued in future studies because of the intimate metabolic relation between alcohol and folate metabolism.

AN - 68429724; 16054987 AB - Chronic and excessive alcohol intake is associated with an increased risk of a variety of cancers (e.g., oral cavity, larynx, esophagus, liver, lung, colorectal, and breast). Retinoids (vitamin A and its derivatives) are known to exert profound effects on cellular growth, cellular differentiation, and apoptosis, thereby controlling carcinogenesis. Lower hepatic vitamin A levels have been well documented in alcoholics. Substantial research has been done, investigating the mechanisms by which excessive alcohol interferes with retinoid metabolism. More specifically, (1) alcohol acts as a competitive inhibitor of vitamin A oxidation to retinoic acid involving alcohol dehydrogenases and acetaldehyde dehydrogenases; (2) alcohol-induced cytochrome P450 enzymes (CYP), particularly CYP2E1, enhance catabolism of vitamin A and retinoic acid; and (3) alcohol alters retinoid homeostasis by increasing vitamin A mobilization from liver to extrahepatic tissues. As a consequence, long-term and excessive alcohol intake results in impaired status of retinoic acid, the most active derivative of vitamin A and a ligand for both retinoic acid receptors and retinoid X receptors. Moreover, this alcohol-impaired retinoic acid homeostasis interferes with (1) retinoic acid signaling (e.g., down-regulates retinoid target gene expression) and (2) retinoic acid "cross-talk" with the mitogen-activated protein kinase [(MAPK), including Jun N-terminal kinase, extracellular signal-regulated kinase, and p38 kinase] signaling pathway. In addition, restoration of retinoic acid homeostasis by retinoic acid supplementation restored the normal status of both retinoid and MAPK signaling, thereby maintaining normal cell proliferation and apoptosis in alcohol-fed animals. These observations would have implications for the prevention of alcohol-promoted liver (and peripheral tissue) carcinogenesis. However, a better understanding of the alcohol-retinoid interaction and the molecular mechanisms involved is needed before retinoids can be pursued in the prevention of alcohol-related carcinogenesis in human beings, particularly regarding the detrimental effects of polar metabolites of vitamin A.

AN - 67842616; 15900941 AB - To compare the virulence of spores of 7 fungi by tracheal inoculation of goats following exposure of goats to an aerosol of sterilized feedyard dust. Animals-54 weanling Boer-Spanish goats. A prospective randomized controlled study was conducted. There were 7 fungal treatment groups, a tent control group, and a pen control group (n = 6 goats/group). Goats in the 7 treatment and tent control groups were exposed to autoclaved aerosolized feedyard dust for 4 hours in a specially constructed tent. Goats in the 7 treatment groups were then inoculated intratracheally with 30 mL of a fungal spore preparation, whereas tent control goats were intratracheally inoculated with 30 mL of physiologic saline (0.9% NaCI) solution. These treatments were repeated each week for 6 weeks. Severity of pathologic changes differed significantly among the 7 fungal treatment groups as determined on the basis of gross atelectatic and consolidated lung lesions and histologic lesions of the lungs. Descending order for severity of lesions was Mucor ramosissimus, Trichoderma viride, Chaetomium globosum, Stachybotrys chartarum, Aspergillus fumigatus, Penicillium chrysogenum, and Monotospora lanuginosa. Trichoderma viride spores were the most invasive and were isolated from the bronchial lymph nodes and thoracic fluid of all 6 goats administered this organism. Spores were observed-histologically in lung tissues harvested 72 hours after inoculation from all treatment groups. 4 of 7 fungal spore types induced significantly larger lung lesions, compared with those induced by the other 3 spore types or those evident in control goats.

AN - 67824567; 15889748 AB - Susceptibility to carbaryl in six Mexican strains of the southern cattle tick, Boophilus microplus (Canestrini), was evaluated with the Food and Agricultural Organization larval packet test. Tick strains from the cattle fever tick quarantine zone in Texas were more susceptible to carbaryl than to coumaphos or diazinon. Compared with the susceptible reference (Gonzalez) strain, Mexican tick strains demonstrated 10.9-59.5-fold resistance to carbaryl. Significant cross-resistance was found between carbaryl and the organophosphate acaricides coumaphos and diazinon. Bioassay results with synergists suggested that metabolic detoxification mechanisms did not play a major role in carbaryl resistance. Resistance to carbaryl was likely conferred by insensitive acetylcholinesterase. The implications of carbaryl resistance in tick eradication and control also are discussed.

Bioassays were conducted to determine whether Summon disks affected the aggregation and feeding behavior of termites and to determine whether the presence of Summon disks caused increased recruitment of termites to wood blocks. When termites encountered the disk, they immediately clustered on top of the disk. Termites were observed aggregating on top of the disk throughout the experiment. Consumption of Summon disks was significantly greater than consumption of cardboard disks in paired choice tests. The presence of a Summon disk on top of a wood block caused a significant increase in consumption of the wood block. Bioassays also were conducted to determine whether water extracts of Summon disks affected termite behavior. Consumption of filter paper disks treated with a water extract of Summon disks was significantly greater than consumption of control filter paper disks. Termites tunneled through sand treated with a water extract of Summon disks faster than they tunneled through untreated sand. In a field test, the rate of infestation of monitoring stations with a Summon disk was 3 times greater than the rate of infestations of stations without a disk.

AN - 67771921; 15844825 AB - Bacteriophages are viruses that infect and kill bacteria. Bacteriophage do not infect animal and plant cells, which makes them a potentially safe alternative to antibiotics. We have been conducting research on the efficacy of bacteriophage to prevent and treat colibacillosis in poultry. Bacteriophages that were lytic to a non-motile, serotype 02 isolate of Escherichia coli were isolated from municipal wastewater treatment plants and poultry processing plants. This E. coli isolate is pathogenic to poultry, causing severe respiratory and systemic infections. Two bacteriophage isolates were selected for use in studies designed to determine the efficacy of these bacteriophage to prevent and treat severe colibacillosis in poultry. Colibacillosis was induced by injecting 6 x 10(4) cfu of E. coli into the thoracic air sac when birds were 1 wk of age. Initial studies demonstrated that mortality was significantly reduced from 85 to 35% when the challenge culture was mixed with equal titers of bacteriophage, and the birds were completely protected when the challenge culture was mixed with 10 pfu of bacteriophage. In subsequent studies, we have shown that an aerosol spray of bacteriophage given to birds prior to this E. coli challenge could significantly reduce mortality even when given 3 d prior to the E. coli challenge. Our research on treating colibacillosis in poultry has demonstrated that an intramuscular injection of bacteriophage given 24 or 48 h after the birds were challenged rescued the birds from this severe E. coli infection. We have demonstrated that bacteriophage can be used to prevent and treat colibacillosis in poultry and may provide an effective alternative to antibiotic use in animal production.

AN - 67769592; 15844820 AB - Eggs that harbor Salmonella in their edible contents pose a significant risk of transmitting disease to consumers. Although Salmonella deposition inside yolks does not usually occur at a high frequency in naturally contaminated eggs, bacterial penetration through the vitelline membrane could lead to rapid and extensive multiplication in the nutrient-rich yolk contents. The present study used an in vitro egg contamination model to assess the ability of Salmonella strains to penetrate the vitelline membrane and multiply inside yolks. An S. enteritidis strain and 2 Salmonella heidelberg strains, initially inoculated onto the outside of the vitelline membrane, were able to enter the yolk contents (at frequencies ranging from 10 to 25% of experimentally contaminated eggs) during 24 h of incubation at 30 degrees C. Variants of these parent strains, obtained by in vivo passage into eggs laid by infected hens, penetrated the yolk membrane at significantly higher frequencies. These results demonstrate that pathogens such as S. enteritidis and S. heidelberg can penetrate into and begin to multiply inside the yolks of contaminated eggs during the first day of storage at warm temperatures.

AN - 67767431; 15844824 AB - Foodborne diseases caused by enterohemorrhagic Escherichia coli, Salmonella, and Campylobacter species are of public health and economic significance. Shedding of these pathogens during production and slaughter are risks for contamination of products for human consumption. Consequently, strategies are sought to prevent or reduce the carriage of these pathogens in food animals before slaughter. Experimental products containing chlorate salts have been proven efficacious in reducing concentrations of E. coli and Salmonella Typhimurium in the gut of cattle, sheep, swine, and poultry when administered as feed or water additives. Mechanistically, chlorate selectively targets bacteria expressing respiratory nitrate reductase activity, such as most members of the family Enterobacteriaceae, as this enzyme catalyzes the reduction of chlorate to lethal chlorite. Most beneficial gut bacteria lack respiratory nitrate reductase activity, and thus the technology appears compatible with many bacteria exhibiting competitive exclusion capabilities. More recently, select nitrocompounds have been investigated as potential feed additives, and although these nitrocompounds significantly reduce pathogens on their own, evidence indicates that they may most effectively be used to complement the bactericidal activity of chlorate. A particularly attractive aspect of the nitrocompound technology is that, as potent inhibitors of ruminal methanogenesis, they may allow producers the opportunity to recoup costs associated with their use. At present, neither chlorate nor the nitrocompounds have been approved as feed additives by the US Food and Drug Administration, and consequently they are not yet available for commercial use.

AN - 67749413; 15830666 AB - This study evaluated the ability of spore-forming Bacillus spp. to resist milk pasteurization conditions from 72 to 150 degrees C. Spores from the avirulent surrogate Sterne strain of Bacillus anthracis, as well as a representative strain of a common milk contaminant that is also a pathogen, Bacillus cereus ATCC 9818, were heated at test temperatures for up to 90 min in dH2O, brain heart infusion broth, or skim milk. In skim milk, characteristic log reductions (log CFU per milliliter) for B. anthracis spores were 0.45 after 90 min at 72 degrees C, 0.39 after 90 min at 78 degrees C, 8.10 after 60 min at 100 degrees C, 7.74 after 2 min at 130 degrees C, and 7.43 after 0.5 min at 150 degrees C. Likewise, log reductions (log CFU per milliliter) for viable spores of B. cereus ATCC 9818 in skim milk were 0.39 after 90 min at 72 degrees C, 0.21 after 60 min at 78 degrees C, 7.62 after 60 min at 100 degrees C, 7.37 after 2 min at 130 degrees C, and 7.53 after 0.5 min at 150 degrees C. No significant differences (P < 0.05) in thermal resistance were observed for comparisons of spores heated in dH2O or brain heart infusion broth compared with results observed in skim milk for either strain tested. However, spores from both strains were highly resistant (P < 0.05) to the pasteurization temperatures tested. As such, pasteurization alone would not ensure complete inactivation of these spore-forming pathogens in dH2O, synthetic media, or skim milk.

AN - 67745875; 15830658 AB - Salmonella serotypes are important foodborne pathogens of humans that can be acquired through consumption of contaminated meat and dairy products. Salmonella infection also can be a significant animal health issue. As part of a national study of U.S. dairy operations conducted between March and September 2002, fecal samples were collected from representative cows in 97 dairy herds in 21 states and were cultured to determine the prevalence of Salmonella shedding. Salmonella was recovered from the feces of at least one cow in 30.9% of the herds. Overall, 7.3% of fecal samples were culture positive for Salmonella. The three most frequently recovered serotypes were Salmonella Meleagridis (24.1%), Salmonella Montevideo (11.9%), and Salmonella Typhimurium (9.9%). The susceptibilities of Salmonella isolates recovered were determined using a panel of 16 antimicrobial drugs. Salmonella isolates recovered from dairy cows had relatively little resistance to these antimicrobial agents; 83.0% of the isolates were susceptible to all antimicrobials tested. This study provides updated information on the prevalence and susceptibility patterns of Salmonella in dairy herds and on cow and herd characteristics. These data contribute to our understanding of the ecology of Salmonella in the dairy farm environment.

AN - 67745024; 15830661 AB - By using an in vitro model simulating the potential opportunities for Salmonella enterica serovar Enteritidis (SE) to proliferate within eggs contaminated with this organism following oviposition, we investigated growth of SE in eggs. Seventy to 140 CFU of one of three SE strains originating either from egg contents, chicken meat, or a human infection were experimentally inoculated onto the vitelline membrane of eggs collected from specific-pathogen-free flocks of chickens and incubated at 25 degrees C. SE organisms were detected in 6 of 71 yolk contents of the eggs inoculated with any of the test strains attaining levels ranging from 2.0 x 10(2) to 4.2 x 10(8) CFU/ml by day 6. The organisms were also detected in the albumen from 38 of 55 eggs tested, growing to levels ranging from 1.0 x 10(2) to 4.3 x 10(8) CFU/ml by day 6 after inoculation. An additional three yolk contents and 15 albumen samples were culture positive for SE following enrichment. There was no correlation between the number of the organisms in the yolk contents and that in the albumen from each of the eggs. When 73 to 91 CFU of the egg strain were inoculated into samples of separated albumen obtained from eggs that were stored at 4 degrees C for 1 to 4 weeks or at 25 degrees C for 1 week, slight growth (3.0 x 10(2) to 7.4 x 10(3) CFU/ml) was found in only 3 of the 60 albumen samples by day 6 after inoculation, but the organisms were recovered from 52 samples following enrichment. The results suggest that the environment on or near the vitelline membrane can be conducive to SE proliferation over time.

AN - 67715308; 15813863 AB - This study explored the existence of apoptosis (programmed cell death) in Ichthyophthirius multifiliis Fouquet (Ich) theronts and determined the effect of cutaneous antibodies in skin culture fluid from fish immune to Ich on theront apoptosis. Apoptosis was detected in theronts and was clearly distinguished by fluorescent microscopy after staining with acridine orange and propidium iodide. The apoptotic theronts showed characteristic chromatin condensation and nuclear fragments containing chromatin pieces. The externalization of phosphatidylserine on the plasma membrane of apoptotic theronts was detected with fluorescein isothiocyanate-conjugated annexin using flow cytometry. Theront apoptosis was induced using the skin culture fluid from fish immune to Ich, which contained cutaneous antibodies against Ich. The highest apoptosis appeared in theronts exposed to immune skin culture fluid at a 1:10 dilution, compared with those at 1:20 and 1:40 dilutions. A direct correlation was noted between the percentage of apoptotic theronts and exposure duration to immune skin culture fluid. The study indicated that antibody reaction with theronts (immobilization) played an important role in theront apoptosis, but it could not be excluded that other components released from the excised skin had effects on theronts.

AN - 67562053; 15797813 AB - Salmonella enterica serotype Typhimurium phagetype DT104 (DT104) is a foodborne pathogen with a multiresistant phenotype conferred by a genomic-based integron structure designated as SGI1. Recently, a novel cytopathic phenotype was ascribed to several isolates of DT104 recovered from veal calves. This phenotype is dependent upon clg, a gene encoding a collagenase in Salmonella. Using a novel transposon system and an RT-PCR assay for detection of clg expression, we identified SlyA as a regulator of the collagenase-mediated phenotype. The function of SlyA, in regards to clg expression, is to repress the synthesis of Clg. Derepression ensued in the absence of SlyA or in the presence of a truncated version of SlyA with the latter being relevant for maintenance of another virulence aspect mediated by SlyA, i.e. survival within macrophages. The SlyA-mediated effect on clg expression was restricted to DT104 and other Salmonella phagetypes and serotypes possessing SGI1 thus suggesting co-regulation by an SGI1-specific component.

The objective of this study was to develop CEC (pH 7 NH4OAc) prediction models that encompass most soils of the United States. The National Soil Survey Characterization database was used to develop the predictive models using general linear models. Data were stratified into more homogeneous groups based on the organic C content, soil pH, taxonomic family mineralogy class and CEC-activity class, and taxonomic order. Models were developed for each strata or data group. Organic matter and noncarbonate clay contents were the main predictor variables used. Water at -1500 kPa was used in lieu of clay content on four groups. Results indicate that between 43 and 78% of the variation in CEC could be explained for the high organic C data groups; between 53 and 84% could be explained for the mineralogy groups; between 86 and 95% could be explained for the CEC-activity class groups; and between 53 and 86% could be explained for the taxonomic orders. The same predictive model was applicable for Gelisols and Histosols. Inceptisols and Alfisols (>0.3% organic C) also shared the same model. In general, the mineralogy/CEC-activity class equations had lower RMSEs than the taxonomic order equations. A decision tree, based on how the data was stratified, guides the selection of which model to use for a soil layer. Validation results indicated that the models, in aggregate, provide a reasonable estimate of CEC for most soils of the United States.

Current knowledge of how soils change is not well synthesized and existing soil surveys include only limited information on the dynamic nature of soils. Providing information about causes and attributes of soil change and the effects of soil change on soil function over the human time scale (centuries, decades, or less) should be a primary objective of 21st century soil survey. Soil change is temporal variation in soil across various time scales at a specific location. Attributes of change include state variables (dynamic soil properties), reversibility, drivers, trends, rates, and pathways and functional interpretations include resistance, resilience, and early warning indicators. Iterative elements of the blueprint for action described in this article are: (i) identify user needs; (ii) conduct interdisciplinary research and long-term studies; (iii) develop an organizing framework that relates data, processes, and soil function; (iv) select and prioritize soil change data and information requirements; (v) develop procedures for data collection and interpretation; and (vi) design an integrated soil-ecosystem-management information system. Selection of dynamic soil properties, soil change attributes, and functional interpretations to be included in future soil surveys should be based on analyses comparing the benefits of meeting user needs to the costs of data acquisition and delivery. Implementation of the blueprint requires increased collaboration among National Cooperative Soil Survey partners and other research disciplines.

Two hundred eleven soil samples from 44 sites were collected, during the soil survey process, for selenium analysis. For study purposes, these sites were broadly classified into three categories; twenty-one sites were irrigated, 19 were non-irrigated, and 3 were waterlogged. Soil samples were prepared by BOR and analyzed by the US Geological Survey. Statistical analysis of the resultant data was conducted by the BOR. A strong correlation exists between soluble selenium and irrigation. Non-irrigated soils average 34 times more soluble selenium, within the immediate soil profile (upper 5 to 9 feet), than irrigated soils. This correlation supports the concept that the soil-water system within the irrigated areas of the watershed is a flushing system, differing greatly from the soil-water system in areas of California. Some of the Mancos-derived soils that have been irrigated for the past 50 or more years have undergone rapid weathering and pedogenesis. Most of the soils once identified in the 1967 Delta-Montrose Soil Survey (field work late 1940s) as residual (less than 40 inches from soil surface to paralithic contact) have exhibited increases in depth ranging from of 20 to greater than 60 inches. These soils have also exhibited clay increases on average of 5 to 7 percent total clay within the soil profile control section. This increase in clay, as a result of sediment-laden irrigation waters and weathering of the Mancos Shale soil materials, has caused the soil classification of many of these irrigated soils to change from fine-silty to fine (less than 35% clay to greater than 35% clay). This ongoing weathering of the soil overburden and paralithic Mancos parent material as a byproduct of irrigation, suggests a continuum of labile salts and heavy metals becoming available for mobilization and transport.

Simulation studies have established that dynamic zoning strategies produce larger tracts of interior, closed canopy forest, thus increasing the value of these landscapes for interior-dependent wildlife. We used the simulation model LANDIS to examine how the implementation of a dynamic zoning strategy would change trajectories of ecological succession in the Great Divide Ranger District of the Chequamegon-Nicolet National Forest in northern Wisconsin over 500 years. The components of dynamic zoning strategies (number of zones in a scenario and the length of the hiatus between successive entries into zones) and their interaction had highly significant impacts on patterns of forest succession. Dynamic zoning scenarios with more zones and shorter hiatus lengths increased the average amount of the forest dominated by early successional aspen (Populus sp.). Dynamic zoning scenarios with two zones produced more late successional mature northern hardwoods than scenarios with four zones. Dynamic zoning scenarios with very short (30 years) or very long (120 years) hiatus lengths resulted in more late successional mature northern hardwoods than scenarios with intermediate hiatus lengths (60 and 90 years). However, none of the dynamic scenarios produced as much late successional mature northern hardwoods as the static alternative. Furthermore, the amounts of all habitat types in all dynamic zoning scenarios fluctuated greatly in time and space relative to static alternatives, which could negatively impact wildlife species that require a stable amount of habitat above some minimum critical threshold. Indeed, implementing dynamic zoning scenarios of different designs would have both positive and negative effects on wildlife species and for other objectives of forest management.

During the first 75 years, many of the most threatening areas of accelerated soil erosion were fenced and seeded with sand stabilizers. These projects had a high success rate, halting the advancement of sand dunes and other forms of highly accelerated erosion. However, they were limited in scope, and often concentrated on the symptoms of the problems rather than the underlying causes, such as improper grazing management. On a national scale, not enough was being achieved in mitigating the extensive ecosystem degradation. This period of soil conservation in Iceland was characterized by single-issue, top-down approaches, a lack of appropriate incentives for soil conservation and weak laws for protection of the rangelands. During the last two decades there has been a gradual shift to more participatory strategies, community involvement, and ecosystem management for multiple benefits. These changes have greatly increased community involvement in projects, stimulated conservation awareness and improved land use. The ties between agricultural policy and soil-conservation issues are also being strengthened, especially by linking part of governmental subsidies for sheep production to land-use factors.

In most species, Hsp90 is essential for proper cell function. In this study, we present the molecular analysis of Hsp90 from Eimeria species, the causative agents of avian coccidiosis. The full-length Eimeria acervulina Hsp90 complementary DNA was isolated from intestinal intraepithelial lymphocytes of Eimeria-infected chickens. From evolutionary analysis and sequence identity, it is likely that Eimeria Hsp90 sequences described thus far encode the cytosolic versions of the protein. Although at the nucleotide and amino acid levels Eimeria tenella and E. acervulina Hsp90 are highly similar, their expression profiles differ considerably. Although E. tenella transcripts were detected in all developmental stages tested, E. acervulina transcripts were not found in oocysts undergoing sporulation or in fully sporulated oocysts, suggesting that messenger RNA expression may be regulated quite differently between Eimeria species.

Quantification of P loss has been pursued through field monitoring, simulation models, and risk assessment indices. However, the intended users of these methods differ, impacting each method's functional design and ease-of-use. For example, the Pennsylvania P Index, a risk assessment tool for planners, requires less discipline-specific knowledge and more readily available data than the Soil and Water Assessment Tool (SWAT), a complex, watershed-level, research-based simulation model. This study compared measured losses of P from the outlet of a 39.5 ha mixed land use watershed (FD-36) in south-central Pennsylvania with watershed-level losses predicted by SWAT. Measured watershed exports of dissolved P (0.06 kg ha super(-1)) and total P (0.24 kg ha super(-1)) during the 7-month sampling period were similar in magnitude to SWAT-predicted losses (0.05 and 0.73 kg ha super(-1), respectively). Additionally, the study compared field-level P losses predicted by SWAT with field-level vulnerabilities to P loss derived by the P Index. The P Index and SWAT categorized 73% of the 22 fields similarly in terms of vulnerability to P loss, with Pearson correlation significant at p = 0.07; all except one of the remaining six fields were over- or underpredicted by a single risk category. Results indicate that while actual P loss from FD-36 was small, three fields contributed a major proportion of this loss. Additionally, this study suggests that the P Index can provide land managers with a reliable assessment of where P loss occurs within a watershed, thus allowing more effective placement and selection of conservation practices, which lead toward improved downstream water quality.

Nucleic acid extracts from individual insects or groups of 5-10 were tested using PCR primers designed from the DNA sequence of 16S-23S rRNA or ribosomal protein genes of the pathogen. The beet leafhopper, Circulifer tenellus (Baker), was most often associated with the phytoplasma, with approximately 16% of the insects testing positive. The phytoplasma was occasionally found associated with Ceratagallia spp. Leafhopper species that were not associated with the phytoplasma included Macrosteles spp., Dikraneura spp., Colladonus montanus (Van Duzee), Circulifer geminatus (Van Duzee), Ballana spp., Amplysellus spp., Paraphlepsius spp., Texananus spp., Balclutha spp., Latalus spp., Erythroneura spp., Exitianus exitiosus (Uhler), and unidentified delphacids. The detected phytoplasma was similar to, or synonymous with, the beet leafhopper-transmitted virescence agent that is associated with the potato purple top disease in the Columbia Basin region of Washington and Oregon. This is in contrast to the phytoplasma associated with potato purple top disease in Mexico that is related to aster yellows (group 16SrI). The association of the group 16SrVI phytoplasma almost exclusively with the beet leafhopper suggests that this insect is the major vector of the phytoplasma in this region.

This study utilizes broiler litter and cake as source materials for granular activated carbon production and optimizes conditions for their production. Pelletized manure samples were pyrolyzed at 700 C for 1 h followed by activation in an inert atmosphere under steam at different water flow rates, for a period ranging from 15 to 75 min. Carbon physical and adsorptive properties were dependent on activation time and quantity of steam used as activant, yields varied from 18% to 28%, surface area varied from 253 to 548 m super(2)/g and copper ion adsorption varied from 0.13 to 1.92 mmol Cu super(2+)/g carbon. Best overall performing carbons were steam activated for 45 min at 3 ml/min. Comparative studies with commercial carbons revealed the broiler cake- based carbon as having the highest copper ion efficiency.

In part, this research has tried to improve our understanding of interconnections between resource management and social and cultural change on the Tongass National Forest in southeast Alaska. In 1997, scientists at the Pacific Northwest Research Station (PNW) initiated a number of social science studies in response to information gaps identified while developing the Tongass Land Management Plan. Results presented here summarize findings from studies of traditional ecological knowledge, subsistence use of natural resources, tourism trends and the effects of tourism on communities, and social acceptability of alternative timber harvest practices. Management implications are discussed along with suggestions for further study.

The effects of monoterpenes and phenolics on stem-colonizing bark beetles and their associated microorganisms have been studied to some extent, but the roles of diterpene acids are largely unknown. Diterpene acids are known to have substantial feeding deterrent and growth inhibiting effects on a variety of insect groups and are known to inhibit a variety of fungi. We tested three diterpene acids present in red pine, Pinus resinosa, at various concentrations, on several life history components of the bark beetle Ips pini and the fungus Ophiostoma ips. No diterpene acid affected the host acceptance behavior or larval survival of Ips pini. In contrast, abietic acid and isopimaric acid strongly inhibited spore germination of O. ips, and abietic acid strongly inhibited mycelial growth. The levels of inhibition observed were higher than with any previous assays of monoterpenes or phenolics in this system. These results support the view that conifer defenses against bark beetle-fungal complexes are multifaceted, with all three phytochemical groups being important to P. resinosa, but each with varying relative activity against the beetles and fungi.

However, there are few broad scale techniques for quantifying the sources of sediment, i.e. upland vs. river bank erosion. This research was designed to evaluate the use of airborne LIDAR for characterizing sediment and phosphorus contributions from river bank erosion. The evaluation was done on the main stem of the Blue Earth River in southern Minnesota. Detailed topographic data were collected on an annual basis in April 2001 and 2002 over a 56 km length of the river with a helicopter mounted Topeye laser system. The raw database included X, Y, Z coordinates of laser returns sampled from the river valley with a density of 1-3.3 elevations per m super(2). Uniform 1 m bare earth digital elevation models were constructed by stripping vegetation laser returns and interpolation. The two models were differenced to determine volume change over time, which was then converted to mass wasting by multiplying volume change with bulk density. Mass wasting rates were further converted to sediment load based on percentage of transportable material in the bank strata. The average difference between LIDAR measured elevations and RTK GPS surveyed elevations on 5 highway bridge surfaces was 2.5 and 8.8 cm for the 2001 and 2002 scans, respectively. The elevation errors were quasi-normally distributed with standard deviation of 6.7 and 6.1 cm for 2001 and 2002, respectively. No elevation or planimetric corrections were made to the laser data before calculating mass wasting rates because it was not possible to determine the source of error or if it was uniform within and between scans. The mass wasting estimate from the LIDAR surveys varied from 23% to 56% of the sediment mass transported past the downstream gauging station depending on the range of textural material that was entrained once in the river.

Expression constructs differed in use of the maize polyubiquitin 1, Mubi-1, or the sugarcane polyubiquitin 9, SCubi9, promoters; presence or absence of a C-terminal HDEL tag for ER retention; and presence or absence of a 6X Histidine tag for metal ion affinity purification. Accumulation of GM-CSF protein ranged from undetectable to 0.02 of total soluble protein. No significant difference was observed between the two promoters; however, the ER retention tag was required for higher accumulation levels. Human bone marrow cells (TF-1), which require GM-CSF for cell division, proliferated when growth media was supplemented with transgenic sugarcane extracts. Comparison to purified commercially produced GM-CSF indicated the sugarcane-produced protein had essentially identical activity levels. In a 14-month field trial, accumulation levels remained stable. This is the first report of field production of GM-CSF. During the field trial, no flowering of the trial plants occurred; no pollen or seed was produced. Drying, burning, and burial of the test plants effectively blocked possible routes for the transgenic sugarcane to enter the environment or food supply. Sugarcane may provide a highly secure system for biofactory production of pharmaceutical proteins.

This concept for the nematodirines excludes the monotypic Lamanema chavezi, but otherwise corroborates generic-level diversity as defined in prior studies. Exhaustive analysis resulted in 1 most parsimonious tree (36 steps; consistency index [CI] = 0.94; retention index [RI] = 0.93; excluding phylogenetically uninformative characters, CI = 0.92). As an inclusive or monophyletic group, Nematodirinae was diagnosed by 8 synapomorphies (7 are unequivocal): (1) large eggs, (2) long filiform spicules, (3) basal division of the dorsal ray, (4) symmetrical membrane enveloping the spicule tips, (5) fused structure of the spicule tips, (6) absence of the gubernaculum, (7) development of the third-stage larva within the egg, and (8) ornamentation in the form of discrete bosses on the bursa. Exclusion of Lamanema will require new assessments of historical biogeography and the evolution of host associations for the nematodirines.

The structure has two stages, with 7 steps, where the stages involve two types of theories: core and auxiliary, which need to be identified in order to explain and evaluate observations and predictions. Core theories are those that are `fundamental to the phenomena being observed, whereas auxiliary theories are those that describe or explain the actual observation process of the phenomena. The formulation of a scientific theory involves three constitutive components or types of judgments: explanative, evaluative, and regulative or aesthetic, driven by reason. Two perspectives guided us in developing the proposed structure: (1) In a risk assessment explanations based on notions of causality can be used as a tool for developing models and predictions of possible events outside the range of direct experience. The use of causality for development of models is based on judgments, reflecting regulative or aesthetic conceptualizations of different phenomena and how they (should) fit together in the world. (2) Weight of evidence evaluation should be based on falsification principles for excluding models, rather than validation or justification principles that select the best or nearly best-fitting models. Falsification entails discussion that identifies challenges to proposed models, and reconciles apparent inconsistencies between models and data. Based on the discussion of these perspectives the 7 steps of the structure are: the first stage for core theories, (A) scientific concepts, (B) causality network, and (C) mathematical model; and the second stage for auxiliary theories, (D) data interpretation, (E) statistical model, (F) evaluation (weight of evidence), and (G) reconciliation, which includes the actual decision formulation.

(More recently, the developer shelved this plan.) In this paper, a quantitative model is used to analyze the possible economic impact of commercializing a crop for which there may be sizable consumer resistance. At issue is whether, and under what conditions, the economic benefits from biotech wheat could be outweighed by economic costs. The analysis also addresses the distribution of costs and benefits among stakeholders: producers, consumers, and US taxpayers. Specific attention is given to the impacts on consumers in non-biotech and biotech market segments, and those in the United States and foreign countries. Under base-case assumptions, the analysis suggests that commercialization of biotech wheat could lead to a small net loss of total economic welfare. Results depend critically on several model parameters: the rate of biotech adoption; unit cost savings for biotech producers; the share of the non-biotech market segment; and extra costs associated with a 'dual marketing system' for wheat.

The tensile strength and elongation at break (%) of films were evaluated as well as their capacity to degrade in compost. Films recovered from soil every 48 h showed consistent degradation (weight loss), diminution of the polymer's characteristic peak absorbance in the carbohydrate fingerprint region of the FTIR, and changes in the surface morphology via scanning electron microscopy (SEM). Anionic starch-chitosan films had much superior tensile strength and elongation compared to cationic starch-pectin, suggesting that the ionic bonds formed between anionic-starch and positively charged groups in chitosan polymer were much more stable and stronger. Initially, both films lost about 36% weight within 96 h, which also correlated well with the loss in the characteristic absorption peaks in the region of the infrared spectrum typical of biopolymers. The total mineralization of films by microorganisms in compost soil was also measured using respirometric techniques. Though the rate of mineralization differed for two formulations, total mineralization (extent) for both films were achieved within 45 days.

Decadal time-scale changes in streamflow variability and lag-1-yr autocorrelation (persistence) were observed. The significance of the variability trends was tested using a jackknife procedure involving the random resampling of seasonal flows from the historical record. The 1930s-50s was a period of low variability and high persistence, the 1950s-70s was a period of low variability and antipersistence, and the period after 1980 was highly variable and highly persistent. In particular, regions from California and Nevada to southern Idaho, Utah, and Colorado have recently experienced an unprecedented sequence of consecutive wet years along with multiyear extreme droughts.

Five of the lakes had been stocked with non-native brook trout (Salvelinus fontinalis) for over 30 y, while fish were absent from the other 5 lakes. Pacific treefrog (Pseudacris regilla) larvae were observed in 40% of fish-bearing lakes and 80% of fishless lakes, rough-skinned newts (Taricha granulosa granulosa) were present in all study lakes, and coastal giant salamanders (Dicamptodon tenebrosus) were present in 40% of fish-bearing lakes. Pacific treefrog larvae were significantly more abundant in fishless lakes, while rough-skinned newt median abundances were identical between fish-bearing and fishless lakes. Differences in Pacific treefrog abundances and distribution between fish-bearing and fishless lakes were likely related to the presence of brook trout, but might also have been influenced by other factors such as lake morphometry and abundance of aquatic vegetation. Modifying the number or type of fish stocked in the Red Buttes Wilderness could reduce effects from fish stocking on Pacific treefrog populations.

Fifty small streams (mean discharge 2.7 L s super(-1), range 0.1-128.1 L s super(-1)) representing three geographic areas (ATC installations) throughout southeastern Alaska were sampled with 250 mu m nets three times per year (April, July, September). Samples were used to assess the subsidy of energy from fishless headwaters to downstream systems containing or potentially containing fish, and to obtain preharvest data on streams for the ATC study. Invertebrates of both aquatic and terrestrial origin were captured, with aquatic taxa averaging roughly 3/4 of the total individuals sampled. Invertebrates and detritus were transported from headwaters during all sampling periods, averaging 163 mg invertebrate dry mass stream super(-1) day super(-1) (1.7 mg m super(-3) water) and 10 g detritus stream super(-1) day super(-1) (0.05 g m super(-3) water), respectively. Based on the frequency of headwater streams in the watersheds studied, and the average amount of food delivered to downstream habitats by these streams, every kilometer of salmonid-bearing stream could receive enough energy from fishless headwaters to support 100-2000 young-of-the- year salmonids. These results illustrate that headwaters are source areas of aquatic and terrestrial invertebrates and detritus, linking upland ecosystems with habitats lower in the catchment. ATC activities are predicted to have variable effects on headwater stream productivity, and subsequent food resources for downstream salmonids. Partial canopy removal is expected to increase solar penetration to the stream and primary and secondary production within these partially harvested sites, and full canopy removal will likely reduce allochthonous inputs of leaf litter into the streams, and reduce stream invertebrate abundance.

The number and extent of extant bogs is in the low hundreds, comprising no more than a few thousand hectares of habitat. These bogs support a large number of plant species of significant conservation concern. Threats to existing bogs include: land use changes, silvicultural impacts, fire scarcity, vehicle damage, negative feral hog (Sus scrofa) impact, and ground water regime alterations. Two pitcher plant bogs on the Angelina National Forest were subjected to severe damage from vehicular impacts that eliminated herbaceous vegetation, disturbed the soil to substantial depths, and initiated severe erosion. A restoration effort that replaced lost soil, reduced erosion, and allowed subsequent revegetation was implemented. Approximately four years post-treatment, bogs are intact, soil erosion is controlled, revegetation is complete or progressing, and at least some species of conservation concern are present in the revegetated areas. These restoration projects have demonstrated that degraded pitcher plant bogs that have suffered severe damage due to vehicular impacts can be substantially restored if sufficient resources are available. However, pitcher plant bogs on the West Gulf Coastal Plain continue to be threatened by uncontrolled off-road vehicles and other impacts. The most insidious threat may be the widespread lack of sufficient fire required to preclude or reverse succession to communities dominated by woody vegetation and the subsequent loss of the herbaceous bog species.

Forest; Freshwater ER - TY - JOUR T1 - An approach to effectiveness monitoring of floodplain channel aquatic habitat: salmonid relationships AN - 19409139; 6203033 AB - Rivers and streams that support anadromous salmonids are an important part of land management planning in southeastern Alaska and the Pacific Northwest of North America. Land managers and planners require a consistent set of protocols that include both the physical and biological aspects of the stream for effectiveness monitoring procedures to evaluate management activities in forested watersheds. We apply a quantitative method to estimate salmonid populations and link these estimates to a set of physical variables used in an assessment of channel condition at the reach scale. We are able to obtain precise estimates of juvenile salmonid populations at the habitat and reach scale; however, we find a lack of strong relationships between channel condition variables and salmonid densities. Nonetheless, a few trends appear, such as relationships between coho salmon and both pools and large wood. A significant and positive relationship exists between coho salmon fry density and two measures of pool frequency. Our results suggest that the response of fish populations to changes in the amount and quality of habitat can be measured by using the tested procedures. Complexity in habitat use, seasonal effects, and external factors tend to mask close relationships between fish populations and physical variables. We also discuss the implications for trophic status for fish populations and how this information may provide a more robust evaluation of land management activities on the aquatic biota in managed watersheds.

The knowledge generated from these studies not only informs the ongoing process of regional natural resource management in southeast Alaska, but also helped to define future directions for research. Topics still needing additional study include issues related to wildlife, aquatic systems and salmon habitat, silvicultural options for forest management, wood products utilization, and social science. The role of science in supporting the development of options for natural resource management of the Tongass National Forest was carefully defined and implemented in order to maintain science objectivity and impartiality. The planning processes in southeast Alaska clearly exemplify a clear example of the recognition that natural resource plans need to be founded on the best available science. The complexity of ecosystems, including the scales at which they are organized and operate, require focused research to answer key questions in tandem with management decisions. Managers want the support of science institutions to bolster the effectiveness, predictability, and credibility of their decisions. The integration of science into the decision making process is far more prevalent today than it once was and will increase in the future as we move to refine management decisions based on a continually increasing body of science on which to base those decisions.

Several exotic mammal species capable of preying on Puerto Rican parrots cohabit the Caribbean National Forest with the only wild population of these parrots. We used tracking plates, monitoring blocks and trapping to index black rats, small Indian mongooses and feral cats in parrot habitat and in public-use areas in the same habitat type. We had high trap success for black rats at all sites (42% of all sites combined), among the highest reported in the world. Rat response to monitoring (nontoxic bait) blocks was universally high, regardless of ground or tree placement. Mongooses were present at all sites, with a greater proportion of plates tracked within the forest than at public-use sites. Cats were present at all forest sites and one of the public-use sites. Presence of the three species did not appear to be linked to human disturbance. Because only 30-40 Puerto Rican parrots survive in the wild, with as few as three pairs nesting in 2002, we concluded that the abundance and pervasiveness of exotic mammalian predators poses a greater threat to the parrots than has been generally acknowledged. This is evidenced by mammalian predation during recent parrot breeding seasons, including six fledglings taken by mongooses and one nest failure from rats during 2000-2003.

Rodents were sampled longitudinally from 1994 to 2001 on 23 trapping webs at 10 locations in the southwestern United States. This study provided an opportunity to apply meta-analysis techniques to an important ecological question. There were sufficient captures by species on 199 occasions (three consecutive nights) to compare general use of space using multi-response permutation procedures (MRPP). The MRPP results were then used in meta-analyses by species to determine if overall effects of spatial clustering of hantavirus-infected mice as well as categorical effects (elevation, season, site, and state) were present. Based on MRPP analyses, overall spatial clustering of hantavirus-infected mice was most pronounced for brush mice, followed by the deer mouse. Meta-analyses indicated significant overall effects of spatial clustering and varying categorical effects (elevation, season, site, state) of infected mice for each species compared. The overlapping space use by rodents might be an important factor affecting the local transmission of several hantaviruses.

Methods and Results:Standard polymerase chain reaction (PCR), using an oligonucleotide sequence, designated TEC1, was shown, in combination with a previously developed primer (LD2) to amplify strains of B. burgdorferi sensu stricto, Borrelia afzelii, and Borrelia garinii, but not the non-Lyme causing B. hermsii or B. turicatae. This primer pair, designated Bbsl, was successfully used to amplify B. burgdorferi sensu lato from skin biopsies of patients with Lyme disease symptoms as well as from Ixodes scapularis, Amblyomma americanum and Dermacentor variabilis ticks. Conclusions:The primer set Bbsl allows for the rapid detection and differentiation of B. burgdorferi sensu lato from non-Lyme disease-causing Borrelia species in ticks and human tissues. Significance and Impact of the Study:The PCR primer set, Bbsl, will greatly facilitate detection of the causative agents of Lyme disease in infected ticks and human skin samples assisting in epidemiological studies, and potentially allowing for a more rapid diagnosis of the disease in patients.

Special attention was directed to solanaceous weed species. Hundreds of Solanum sarrachoides Sendt. ex. Mart. (hairy nightshade) plants with numerous leaf lesions and moderate defoliation were seen. The frequency of blighted hairy nightshade approximated the frequency of late blight in the adjoining potato fields. Lesions typically contained extensive, white, superficial mycelia colonizing the abaxial and adaxial leaf surfaces. Samples placed in a moist chamber produced lemon-shaped sporangia. On the basis of morphological characteristics, the pathogen was tentatively identified as Phytophthora infestans (Mont.) de Bary. Isolates were obtained by surface-disinfecting leaf sections collected from two locations for 2 to 3 min in 0.5% NaOCl and placing the sections on rye grain medium amended with antibiotics (100 ppm each of penicillin G, pimaricin, and polymyxin). P. infestans was confirmed after reisolating onto rye-lima bean medium. Pathogenicity was tested on detached potato, tomato, and hairy nightshade leaves; the undersides of all leaflets from replicate plants were inoculated with droplets of swimming zoospores ( greater than or equal to 500 zoospores per droplet), the leaves were kept at 17 degree C and 100% humidity, and the extent of sporulation was evaluated after 4, 6, and 7 days. With eight isolates obtained from S. sarrachoides, Koch's postulates were completed on potato and hairy nightshade. Radial growth responses of these strains on rye grain agar amended with 1, 10, or 100 mu g per ml of metalaxyl (Ridomil 2E) yielded 50% effective dose values greater than 100 mu g per ml, since percentage growth at the highest fungicide concentration exceeded 50% of the no metalaxyl control. These resistance levels are typical of the metalaxyl-insensitive strains of P. infestans isolated from potatoes in this area in recent years, which were previously found to correlate with metalaxyl resistance in bioassays using potato tissues. Eight single-sporangial isolates were homozygous for glucose-6-phosphate isomerase and peptidase (Gpi 100/111/122, Pep 100/100). All eight were A2-mating type and mitochondrial haplotype Ia, characteristics common to the US-8 clonal lineage of P. infestans from potato, which may infect a wider host range than the old US-1 clonal lineage. When evaluated on differential hosts, three isolates were tomato race PH-1 and complex potato race R 0,1,2,3,4,9,11. DNA fingerprint analysis with probe RG57 further established that the eight hairy nightshade isolates were identical to each other and to local P. infestans isolates from potato. To our knowledge, this is the first report of infection of S. sarrachoides by P. infestans in Maine. The pathogen was previously isolated from this host during field surveys in southern California in the 1980s in connection with late blight of tomato. Hairy nightshade has been shown to be a host for US-1, US-8, and US-11 isolates of P. infestans in a laboratory setting. The epidemiological significance of S. sarrachoides as an alternative or overwintering host of P. infestans is currently being assessed.

Kerwin) from a plant at the Arctic Plant Germplasm Research and Introduction Project in Palmer, AK. Extracts of leaf tissue tested positive for a potyvirus using indirect enzyme-linked immunosorbent assay (ELISA) and western blots with a monoclonal antibody specific to the potyvirus group (Agdia, Inc., Elkhart, IN). During the following growing season (June 2004), obvious chlorotic ringspots developed into red lesions on the same plant and an adjacent plant of the same cultivar. Partially purified particles that were isolated from the infected rhubarb plants were mechanically inoculated to an experimental host range (number of infected plants per total number of plants), resulting in lesions on leaves of Rheum palmatum (1 of 2) and Chenopodium amaranticolor (3 of 5) but none on C. quinoa (0 of 4). The leaves with local lesions from C. amaranticolor were ground in phosphate buffer (1 g of tissue per 10 ml of buffer), and the extract rubbed onto a set of plants resulting in lesions on R. hybridum (raponticum) (1 of 2), C. amaranticolor (1 of 4), and C. quinoa (1 of 4). The original diseased rhubarb plants and experimental symptomatic plants were confirmed to have a potyvirus using ELISA. Subsequent compound direct ELISA and western blot assays revealed that the virus reacted strongly to monoclonal or polyclonal antibodies to Turnip mosaic virus (TuMV) (Agdia, Inc.). Total RNA was extracted from leaves of the naturally infected rhubarb plants with an RNeasy Plant Mini Kit (Qiagen Sciences, Germantown, Maryland), and used in reverse-transcription-polymerase chain reaction (RT-PCR) with specific primers for TuMV predicted to amplify a 1,134-bp 3'-terminal cDNA fragment encompassing the 3'-end of the nuclear inclusion protein gene (NIb), the coat protein gene, and the 3'-nontranslated region. A PCR product of approximately the expected size was obtained and then sequenced. Sequences (1,077 nt) that corresponded to the TuMV coat protein gene and 3'-terminal noncoding region were submitted to Genbank (Accession No. AY744930). Blast searches against NCBI (National Center for Biotechnology Information) contained high identities to many TuMV isolates with up to 96% (1,043 of 1,077) nucleotide identity (i.e., GenBank Accession No. AF169561). Similar high identities of up to 97% at the amino acid level occurred within the coat protein coding region (i.e., GenBank Accession No. BAC02892.1). Infected rhubarb plants were removed from the site and none of the remaining 109 plants tested positive for TuMV using ELISA. On the basis of the mechanical transmission to plant hosts, the definitive TuMV serology, and the consensus of sequenced regions with TuMV, we concluded that the causal agent of the diseased rhubarb plants was TuMV. Although TuMV has a wide plant host range occurring worldwide, to our knowledge, this is the first report of TuMV in rhubarb in Alaska and the first time that TuMV has been detected in Alaska.

This economic-based categorization of forest types tends to mask critical information relevant to other contemporary forest-management issues, such as modeling forest structure, ecosystem diversity, or wildlife habitat. We propose the joint distribution of tree density and mean tree diameter as a more comprehensive set of forest measures. Focusing on those measures, we build a predictive-mapping model by using existing geographic information system data resources and existing ground-sampled inventory data. The utility of our predictive-mapping model will need to be tested with additional intensive ground-sampled data and in applications that involve forest managers, planners, and biologists. Such tests will reveal the model's utility in addressing contemporary forest- management problems and information needs.

We examine a case in southeast Alaska to illustrate the breadth of these challenges and an approach to developing a science-based resource plan. Not only was the planning area, the Tongass National Forest, USA, exceptionally large (approximately 17 million acres or 6.9 million ha), but it also is primarily an island archipelago environment. The water system surrounding and going through much of the forest provides access to facilitate the movement of people, animals, and plants but at the same time functions as a barrier to others. This largest temperate rainforest in the world is an exceptional example of the complexity of managing at such a scale but also illustrates the role of science in the planning process. As we enter the 21st century, the list of questions needing scientific investigation has not only changed dramatically, but the character of the questions also has changed. Questions are contentious, cover broad scales in space and time, and are highly complex and interdependent. The provision of unbiased and objective information to all stakeholders is an important step in informed decision-making.

Our intention was to provide policymakers and managers with some of the information needed to evaluate the merits of extensive (custodial) and intensive (various levels of thinning) management options for young-growth forests in southeast Alaska. At rotation ages of about 70 years, a prescription that included a precommercial thinning (PCT) to 3.7 m x 3.7 m spacing at 20 years (PCT 12) produced more merchantable volume than three other prescriptions: 5.5 m x 5.5 m precommercial thinning at 20 years (PCT 18), commercial thinning to 6.1 m x 6.1 m at 60 years (CT), and a passive management prescription (PAS) with no stand tending. A combination of PCT and CT was also examined for the 110-year rotation. The PCT 18 prescription usually produced lower merchantable volume than the other prescriptions and was never better than next to the last in merchantable volume production. In the longer rotations, the PAS prescription caught up with the PCT 12 prescription on both a high-productivity site (Sitka spruce [Picea sitchensis] height of 27.4 m in 50 years [high site class, 90 ft]) and a low-productivity site (Sitka spruce height of 18.3 m in 50 years [low site class, 60 ft]). Wood grown under the PAS, CT, and PCT + CT prescriptions is expected to have a broader product potential than the PCT prescriptions. This should allow manufacture of higher value products from the non-PCT prescriptions. As a result, revenue per m super(3) from both the CT and the PAS prescriptions surpassed the PCT 12 prescription at 110 and 150 years, but no economic analysis was conducted to examine returns on investments for the different prescriptions.

Sustained population viability of wildlife species was identified as a major issue in the TLMP planning process. Several species were identified as management indicator species, and research was conducted to determine their potential sensitivity to forest management. Southeastern Alaska was found to be a region with an especially high degree of endemism in its small mammal fauna, principally because of the combination of its archipelago geography combined with highly dynamic glacial history. Two species of endemic small mammals selected for demographic study, however, appeared to be less dependent on old- growth forests than had been suspected at the time TLMP was written: the northern flying squirrel (Glaucomys sabrinus) because of relatively high suitability of noncommercial, low-volume, mixed-conifer forest; and the southern red-backed vole (Clethrionomys gapperi) because of relatively high suitability of precommercially thinned young-growth forest. The northern goshawk (Accipiter gentilis) was found to be problematic for "management indicator" status because of logistical difficulties involved in monitoring this relatively rare, highly mobile species that frequently changes nest sites. Sampling protocols were developed for marbled murrelet (Brachyramphus marmoratus), although murrelet populations do not appear to be in trouble on the Tongass. The conservation strategy of TLMP for American marten (Martes americana) appeared to be sound on Chichagof Island where marten have been studied intensively, but implications for the rest of southeastern Alaska were unclear without further work. Studies of the Alexander Archipelago wolf (Canis lupus ligoni) indicated that population density of black-tailed deer (Odocoileus hemionus) and road access (to wolf hunters) were the predominant factors affecting wolf productivity and mortality, respectively. Finally, studies of bird community response to timber-harvest alternatives to clearcutting indicated that although creation of forest "edge" may increase nest predation rates, the actual response depends on a broad array of factors and is highly variable. We suggest that research, development, and application focus on plant and animal communities and management of vegetation to achieve specific objectives for wildlife habitat. We suggest that such efforts emphasize silviculture of second- growth forests, understanding old-growth reserves, distribution of endemic small mammals, and alternatives to clearcutting. Models for evaluating black-tailed deer habitat and populations are needed for subsistence-hunting management, and some work needs to be directed at interactions between tourism and selected wildlife species.

The objective of this research was to identify resistance genes in response to leaf spot disease using microarray and real-time polymerase chain reaction (PCR). To identify transcripts involved in disease resistance, we studied the gene expression profiles in two peanut genotypes, resistant or susceptible to leaf spot disease, using cDNA microarray containing 384 unigenes selected from two expressed sequenced tag (EST) cDNA libraries challenged by abiotic and biotic stresses. A total of 112 spots representing 56 genes in several functional categories were detected as up-regulated genes (log sub(2) ratio > l). Seventeen of the top 20 genes, each matching gene with known function in GenBank, were selected for validation of their expression levels using real-time PCR. The two peanut genotypes were also used to study the functional analysis of these genes and the possible link of these genes to the disease resistance trait. Microarray technology and real-time PCR were used for comparison of gene expression. The selected genes identified by microarray analysis were validated by real-time PCR. These genes were more greatly expressed in the resistant genotype as a result of response to the challenge of C. personatum than in the susceptible genotype. Further investigations are needed to characterize each of these genes in disease resistance. Gene probes could then be developed for application in breeding programs for marker-assisted selection.

The classic Alaback [Ecology 63 (1982) 1932] model of postlogging succession has dominated ecological thinking in the region for the past two decades. Understory vegetation is believed to increase dramatically immediately after logging but decrease to near-zero levels as the young stands attain conifer canopy closure. Depauperate understories are believed to persist for >100 years. Early studies indicated that understory response to thinning of even-aged stands is mainly by dominant shrubs and is short-lived; response by herbs, especially forbs, is slight. Western hemlock (Tsuga heterophylla) was identified as a potential long-lived, second layer, understory dominant in stands thinned to wide spacing. Recent studies, however, indicate three important deviations from conventional wisdom: (1) Red alder (Alnus rubra)- conifer, even-aged stands produce species-rich and high-biomass understories comparable to those of old-growth forests and much greater than similar-aged pure conifer stands. (2) "Commercial thinning" of older, even-aged stands may result in much greater understory biomass, including forbs, than previously thought, but time requirements might be longer than previously thought. (3) Extrapolation of data from small scales of research plots to large scales of timber-management stands tends to greatly overestimate stand homogeneity and underestimate understory biomass of even-aged conifer stands. The new findings provide a basis for renewed research into even-aged stand management in southeastern Alaska. I suggest a two-pronged approach emphasizing autecological studies of light and soil requirements of major understory species coupled with an "engineering" approach to designing optimal understory environments through silviculture. New silviculture prescriptions can be designed for specific understory objectives. Testing and application of new prescriptions is recommended at the scale of timber-management stands through adaptive management studies in collaboration between the Pacific Northwest Research Station and the Tongass National Forest.

In weed biological control, the host range of a prospective agent is one of the most important considerations in its implementation. Extensive host testing tests seek to determine the behavioral acceptance and nutritional value of different test plant species to the potential agent. A list of test plants is compiled that comprises species that are close taxonomic relatives of the target weed plus other species of economic or ecologic importance. The host testing of the Melaleuca quinquenervia biological control agent Oxyops vitiosa indicated that larvae would accept and complete development on the Australian target weed M. quinquenervia, two Australian ornamental species, Callistemon citrina, Callistemon viminalis (all Myrtaceae). However, the larvae did not complete development when fed a North American species Myrica cerifera (Myricaceae). The study reported here confirms these results and examines the nutritional and performance differences in O. vitiosa larvae fed leaves of these species. The leaf quality factors, percent moisture, percent nitrogen, toughness, and terpenoid content were related to larval survival, performance and digestive indices. The results indicate that plant quality among the Myrtaceae species was generally similar and correspondingly larval survival, performance and digestive indices differed little when larvae were fed leaves of these species. However, significant differences occurred in the plant quality of the North American M. cerifera compared with the Australian species which had leaves with the lowest percent moisture, lowest leaf toughness, highest percent nitrogen. This species, however, is not a physiological host as none of the neonates survived to pupate. When third instars were switched to M. cerifera from their normal host M. quinquenervia reductions were found in survival, biomass gain, digestive efficiency, and conversion of digested food to insect biomass. The marginal acceptance of this North American native plant in laboratory bioassays appears related to the terpenoid chemistry that has similarities to the taxonomically unrelated host M. quinquenervia. However, the high larval mortality corresponds to several novel terpenoids that are not present in the host. For weed biological control host testing these results indicate that M. cerifera is a poor host for O. vitiosa. Additionally, future test plant lists should include plants with secondary metabolites similar to the target weed as these compounds may constitute behavioral cues that are relevant to these specialized herbivores.

Weed control and cover cropping may affect AM fungi directly, through destruction of extraradical hyphae by soil disruption, or indirectly, through effects on populations of mycorrhizal weeds and cover crops. We examined the effects of weed control (cultivation, post-emergence herbicides, pre-emergence herbicides) and cover crops (Secale cereale cv. Merced rye, x Triticosecale cv. Trios 102) on AM fungi in a Central Coast vineyard. Seasonal changes in grapevine mycorrhizal colonization differed among weed control treatments, but did not correspond with seasonal changes in total weed frequency. Differences in grapevine colonization among weed control treatments may be due to differences in mycorrhizal status and/or AM fungal species composition among dominant weed species. Cover crops had no effect on grapevine mycorrhizal colonization, despite higher spring spore populations in cover cropped middles compared to bare middles. Cover crops were mycorrhizal and shared four AM fungal species (Glomus aggregatum, G. etunicatum, G. mosseae, G. scintillans) in common with grapevines. Lack of contact between grapevine roots and cover crop roots may have prevented grapevines from accessing higher spore populations in the middles.

In order to determine the possible risks that occur when there are small numbers of cells, stochastic models of growth are needed that would capture the distribution of the number of cells over replicate trials of the same scenario or environmental conditions. This paper provides a simple stochastic growth model, accounting only for inherent cell-growth variability, assuming constant growth kinetic parameters, for an initial, small, numbers of cells assumed to be transforming from a stationary to an exponential phase. Two, basic, microbial sets of assumptions are considered: serial, where it is assume that cells transform through a lag phase before entering the exponential phase of growth; and parallel, where it is assumed that lag and exponential phases develop in parallel. The model is based on, first determining the distribution of the time when growth commences, and then modelling the conditional distribution of the number of cells. For the latter distribution, it is found that a Weibull distribution provides a simple approximation to the conditional distribution of the relative growth, so that the model developed in this paper can be easily implemented in risk assessments using commercial software packages.

The topology of a generic-level phylogenetic hypothesis, patterns of diversity, and geographic distributions for respective nematode taxa in conjunction with data for host occurrence are consistent with primary distributions determined across Beringia for species of Murielus, Rauschia, Nematodirus, and Nematodirella. Ancestral hosts are represented by Lagomorpha, with evidence for a minimum of 1 host-switching-event and subsequent radiation in the Artiodactyla. Diversification may reflect vicariance of respective faunas along with episodic or cyclical range expansion and isolation across Beringia during the late Tertiary and Quaternary. Secondarily, species of Nematodirus attained a distribution in the Neotropical region with minimal diversification of an endemic fauna represented by Nematodirus molini among tayassuids, Nematodirus lamae among camelids and Nematodirus urichi in cervids during the Pleistocene. Nematodirines are a core component of an Arctic-Boreal fauna of zooparasitic nematodes (defined by latitude and altitude) adapted to transmission in extreme environments characterized by seasonally low temperatures and varying degrees of desiccation. The history and distribution of this fauna is examined in the context of biotic and abiotic determinants for geographic colonization and host switching with an exploration of predicted responses of complex host-parasite systems to ecological perturbation under a regime of global climate change.

Previous reports describe the behavior of E. coli O157:H7 in ground beef under different storage conditions; however, models are lacking for the pathogen's behavior in raw ground beef stored over a broad range of temperature. Using sterile irradiated raw ground beef, the behavioral kinetics of 10 individual E. coli O157:H7 strains and/or a 5-or 10-strain cocktail were measured at storage temperatures from 5 to 46 C. Growth occurred from 6 to 45 C. Although lag phase duration (LPD) decreased from 10.5 to 45 C, no lag phase was observed at 6, 8, or 10 C. The specific growth rate (SGR) increased from 6 to 42 C then declined up to 45 C. In contrast to these profiles, the maximum population density (MPD) declined with increasing temperature, from approximately 9.7 to 8.2 log cfu/g. Bias (B sub(f)) and accuracy (A sub(f)) factors for an E. coli O157:H7 broth-based aerobic growth model (10 to 42 C) applied to the observations in ground beef were 1.05, 2.70, 1.00 and 1.29, 2.87, 1.03, for SGR, LPD and MPD, respectively. New secondary models increased the accuracy of predictions (5 to 45 C), with B sub(f) and A sub(f) for SGR, LPD, and MPD of 1.00, 1.06, and 1.00 and 1.14, 1.33, and 1.02, respectively. These new models offer improved tools for designing and implementing food safety systems and assessing the impact of E. coli O157:H7 disease.

Resistance is limited in commercial pea cultivars. Real-time fluorescent PCR assay specific for A. euteiches was used to study the relationship between disease severity and pathogen DNA content in infected peas. Five pea genotypes ranging in levels of resistance were inoculated with five isolates of A. euteiches. Plants were visually rated for disease development and the amount of pathogen DNA in roots was determined using the PCR assay. The susceptible genotypes Genie, DSP and Bolero tended to have significantly more disease and more pathogen DNA than the resistant genotypes 90-2079 and PI 180693. PI 180693 consistently had less disease, while 90-2079 had the lowest amount of pathogen DNA. The Spearman correlation between pathogen DNA quantity and disease development was positive and significant (P < 0.05) for three isolates, but was not significant for two other isolates. This suggests that the real-time PCR assay may have limited application as a selection tool for resistance in pea to A. euteiches. Its utility as a selection tool would be dependent on the correlation between disease development and pathogen DNA content for a given pathogen isolate. The accuracy and specificity of the real-time PCR assay suggests considerable application for the assay in the study of mechanisms of disease resistance and the study of microbial population dynamics in plants.

While studies of natural communities generally refute this hypothesis, reporting positive relationships between native species diversity and invasibility, some local-scale studies have instead obtained negative relationships. Most treatments of the topic have failed to recognize that all exotic invaders do not behave alike: while "weak" invaders become minor components of communities, "strong" invaders become community dominants at the expense of native species. At the same time, the specific impacts of strong invaders on communities are poorly documented yet critical to understanding implications of diversity loss. With these shortfalls in mind, we examined local-scale relationships between native and exotic plant taxa in bunchgrass communities of western Montana, USA. We found that measures of native species diversity and invasibility were positively correlated in communities with low levels of invasion where both weak and strong invaders occurred at low densities, but negatively correlated in communities with high levels of invasion where the strong invader Centaurea maculosa dominated. Furthermore, at both low and high levels of invasion, weak invaders tended to vary positively with native species richness while strong invaders varied negatively. Weak invaders determined positive overall relationships between native and exotic species in low invasion communities and appeared to coexist with native taxa. Strong invaders prevailed in high invasion communities, driving negative overall relationships therein. That negative relationships primarily reflected strong invader impacts was supported by the fact that negative correlations of C. maculosa with native species diversity and abundance held when we statistically controlled for levels of native species representing preinvasion conditions. In addition, negative associations of C. maculosa with native taxa varied in strength by functional group and species, with large effects on numerically dominant species, suggesting a dramatic shift in community composition and structure. The distinction between weak and strong invaders is important for reconciling conflicting results from previous studies of natural communities, and moving attention beyond the current debate surrounding the biotic resistance hypothesis.

A highly efficacious S. agalactiae vaccine was developed using extracellular products (ECP) and formalin-killed whole cells of S. agalactiae. The vaccine efficacy following storage of S. agalactiae ECP and formalin-killed S. agalactiae cells at 4 degree C for 1 year was determined. The stored ECP containing S. agalactiae formalin-killed cells failed to prevent morbidity and mortality among the vaccinated fish, and the relative percentage survival was 29. Serum antibody responses of the stored ECP and freshly prepared ECP against soluble whole cell extract of S. agalactiae indicated that significantly less antibody was produced in fish immunized with stored ECP and S. agalactiae cells than in those fish immunized with freshly prepared ECP and S. agalactiae cells at day 31 post-vaccination. Silver staining of sodium dodecyl sulphate-polyacrylamide gels and immunostaining of Western blots with tilapia antiserum to S. agalactiae revealed that predominant 54 and 55 kDa bands were present in the freshly prepared ECP fraction. The 55 kDa band was absent from the stored ECP and new bands below 54 kDa appeared on the Western blot. The results of this study on S. agalactiae ECP provide evidence for a correlation between protection and antibody production to ECP and for the importance of the 55 kDa ECP antigen for vaccine efficacy.

To provide empirical evidence of climatic controls, it would be helpful to define climatic regions that minimized variance in key climate attributes, within climatic regions--define the periods and features of climatic regimes, and then look for concordance between regional climate and ecosystem patterns or processes. In the past, these steps have not been emphasized. Before we evaluated the recent climate of the northwestern United States, we established a Northwest climatic region by clustering time series of the Palmer Drought Severity Index (PDSI) for the period of 1675-1978, for the western United States. The background climatic regime and anomalies of the recent northwestern U.S. climate were then identified through temporal pattern analysis involving application of correspondence analysis to the same PDSI time series. Our analysis distinguished 10 distinct periods and four unique types of regimes (climatic signals). Five of the 10 periods (79% of the similar to 300-year record) were marked by mild and equitable moisture conditions (Pacific regime), the "background" climate of the Northwest. The remaining periods were anomalies. Two periods displayed a high-variance, mixed signal marked by switching between severe to extreme annual to interannual dry and wet episodes (High/Mixed regime; 9% of the record). Two more periods displayed a moderate-variance, mixed signal marked by switching between moderate to severe annual to interannual dry and wet episodes (Moderate/Mixed regime; 5%). Only one period was unidirectional and relatively low variance, marked by persistent yet mild to moderate drought (Low/Dry regime, 7%). Our method distinguished decadal- to interdecadal-scale regimes, defined regime periods, and detected both mixed and unidirectional anomalies from the background climate. The ability to distinguish the variance, direction, and period of sequential climatic regimes provides a plausible basis for examining the role of past climate within terrestrial ecosystems of the Northwest. For example, we found concordance between the period of the Low/Dry anomaly and a period of tree establishment in the Olympic Mountains of Washington, close alignment between tree growth with the Moderate/Mixed and High/Mixed signals in Oregon, and a mixed fire response to mixed climatic signals in northeastern Oregon. Linking historical climatic regimes to particular ecosystem patterns and processes also aids in the prediction of future ecosystem changes by providing evidence of the kinds of interactions that may be anticipated.

Three features of the planning process were unique to the revision of the Tongass National Forest plan. First, a major goal was to produce a landscape-scale plan for long-term resource sustainability. Second, the 23-person planning team included six research scientists as full members. Finally, an agreement was reached between the Pacific Northwest Research Station and the Tongass National Forest to collaborate and obtain high-priority information needed for the next planning cycle. Benefits accrued to the Pacific Northwest Research Station by demonstrating the relevance of sound science in successful forest planning. Benefits also accrued to the USDA Forest Service Alaska Region in more informed, credible, and defensible decisions.

We develop and test a set of effectiveness monitoring procedures for measuring change in floodplain channel habitat in southeastern Alaska. Variables include measures of channel morphology, pool size, pool spatial density, and bed surface grain size distribution. These procedures provide methods of data collection and analysis that, in the context of a statistically defensible sampling protocol, allow for determination of rate and direction of change among different intensities of land use, and thereby evaluation of management strategies. Assessment of channel condition can also contribute to evaluation of both restoration needs and success of restoration activities. Information gained from these procedures, together with information, where available, on watershed and riparian condition and processes and land use history will contribute to interpretation of measured change and its linkage to specific disturbances. Relationships among channel condition indicators and salmonid densities as well as opportunities for future research to better understand ecosystem elements that support biologic productivity are addressed in a companion paper in this volume (Bryant and Edwards).

Estimates of forest and other vegetation resources are presented to provide managers with information about the character of the resource. Slightly less than half (48%) of southeast Alaska has some type of forest land cover, about 29% has nonforest vegetation, and the remaining 33% is barren or water. Most forest land (85%) and nonforest vegetation (77%) is managed by the U.S. Forest Service, Alaska Region (Region 10), Tongass National Forest. Estimates of change (excluding timber harvest) are presented for the forest component of the resource base. In general, forest growth exceeds mortality by a ratio of roughly 3 to 2. With the framework of the Alaska vegetation classification system (AVCS) as a basis, vegetation types were described and species richness and diversity values among the modified AVCS types were estimated. The highest species richness of vascular plants in closed forest occurs in the western hemlock-Alaska cedar type, the lowest in the Sitka spruce type. In the open forest category, the highest species richness is in the mixed conifer type and the lowest is again in the Sitka spruce type.

The temperate rainforest of the region regenerates and develops slowly, and old- forest characteristics do not appear until 300 years following disturbance. The challenges of managing forest resources are intensified in island archipelagos because of the increased sensitivity of indigenous biota to disturbance and higher rates of extinction, especially among endemic organisms. Early expeditions of the large islands of the Alexander Archipelago (1% of all named islands) documented 27 endemic mammalian taxa. More recent studies with modern techniques found that some reputed endemics showed nominal levels of genetic divergence from other conspecific populations, but more divergence existed among several taxa than was reflected in the current taxonomy. Furthermore, the mammal fauna of southeastern Alaska has a nested structure with complex phylogeographic patterns suggesting multiple colonization events. Of eight taxa examined through phylogeographic analyses, five species showed acute genetic variation and divergence in mitochondrial sequences. Four species were comprised of coastal and continental clades (i.e. populations of recent common descent), whereas the fifth species showed a third clade. Conversely, the northern flying squirrel (Glaucomys sabrinus) and southern red-backed vole (Clethrionomys gapperi) were represented by relatively shallow divergent lineages. Still, G. sabrinus showed a distinct mitochondrial lineage on 11 islands (Prince of Wales Island complex), which exhibited severely reduced genetic variation. Moreover, flying squirrels in southeastern Alaska are genetically distinct from populations in the Pacific Northwest; as different as each is from the southern flying squirrel (G. volans). Recent ecological studies of endemic populations of the northern flying squirrel and the southern red-backed vole (reputed old-growth associates) suggest that risk of extirpation in managed landscapes is likely less than was presumed during recent land management planning in the region because: (1) abundant noncommercial forests apparently contribute to breeding populations of northern flying squirrels, which appear to have a more general lifestyle than populations in the Pacific Northwest; and (2) red-backed vole populations may be able to exist in managed young-growth stands that originated from clearcut logging. Still, there are essential questions for both species regarding the influence of annual population fluctuations on habitat distribution and population demography, stand and landscape features that restrict dispersal, and vegetative and structural characteristics of second-growth stands that will sustain breeding populations of both species.

The objective of this study was to determine if an in vitro ruminal fermentation assay used in forage quality research was predictive of results obtained using a conventional biomass-to-ethanol conversion assay. In the conventional assay, herbaceous biomass samples were converted to ethanol by Saccharomyces cerevisiae cultures in the presence of cellulase enzymes. Cultures were grown in sealed serum bottles and gas production monitored by measuring increasing headspace pressure. Gas accumulation as calculated from the pressure measurements was highly correlated (r super(2)>0.9) with ethanol production measured by gas chromatography at 24 h or 7 days. The same feedstocks were also analyzed by in vitro ruminal digestion, as also measured by gas accumulation. Good correlations (r super(2) similar to 0.63-0.82) were observed between ethanol production during simultaneous saccharification and fermentation and gas accumulation in parallel in vitro ruminal fermentations. Because the in vitro ruminal fermentation assay can be performed without sterilization of the medium and does not require aseptic conditions, this assay may be useful for biomass feedstock agronomic and breeding research.

Current mapping algorithms cannot handle so many data without building hierarchies of framework maps. RESULTS: A version of Kruskal's minimum spanning tree algorithm can solve any genetic mapping problem that can be stated as marker deletion from a set of linkage groups. These include backcross, recombinant inbred, haploid and double-cross recombinational populations, in addition to conventional deletion and radiation hybrid populations. The algorithm progressively joins linkage groups at increasing recombination fractions between terminal markers, and attempts to recognize and correct erroneous joins at peaks in recombination fraction. The algorithm is O (mn super(3)) for m individuals and n markers, but the mean run time scales close to mn super(2). It is amenable to parallel processing and has recovered true map order in simulations of large backcross, recombinant inbred and deletion populations with up to 37 005 markers. Simulations were used to investigate map accuracy in response to population size, allelic dominance, segregation distortion, missing data and random typing errors. It produced accurate maps when marker distribution was sufficiently uniform, although segregation distortion could induce translocated marker orders. The algorithm was also used to map 1003 loci in the F sub(7) ITMI population of bread wheat, Triticum aestivum L. emend Thell., where it shortened an existing standard map by 16%, but it failed to associate blocks of markers properly across gaps within linkage groups. This was because it depends upon the rankings of recombination fractions at individual markers, and is susceptible to sampling error, typing error and joint selection involving the terminal markers of nearly finished linkage groups. Therefore, the current form of the algorithm is useful mainly to improve local marker ordering in linkage groups obtained in other ways.

We report the complete genome sequence of Brucella abortus field isolate 9-941 and compare it to those of Brucella suis 1330 and Brucella melitensis 16 M. The genomes of these Brucella species are strikingly similar, with nearly identical genetic content and gene organization. However, a number of insertion-deletion events and several polymorphic regions encoding putative outer membrane proteins were identified among the genomes. Several fragments previously identified as unique to either B. suis or B. melitensis were present in the B. abortus genome. Even though several fragments were shared between only B. abortus and B. suis, B. abortus shared more fragments and had fewer nucleotide polymorphisms with B. melitensis than B. suis. The complete genomic sequence of B. abortus provides an important resource for further investigations into determinants of the pathogenicity and virulence phenotypes of these bacteria.

To test the feasibility of protecting animals through genetic engineering, transgenic cows secreting lysostaphin at concentrations ranging from 0.9 to 14 mg/ml in their milk were produced. In vitro assays demonstrated the milk's ability to kill Staphylococcus aureus. Intramammary infusions of S. aureus were administered to three transgenic and ten nontransgenic cows. Increases in milk somatic cells, elevated body temperatures and induced acute phase proteins, each indicative of infection, were observed in all of the nontransgenic cows but in none of the transgenic animals. Protection against S. aureus mastitis appears to be achievable with as little as 3 mg/ml of lysostaphin in milk. Our results indicate that genetic engineering can provide a viable tool for enhancing resistance to disease and improve the well-being of livestock.

Of the 331 green tree frogs observed, 88% were in canopy gaps. Likewise, higher numbers and biomasses of insects were captured in the open gap habitat. Flies were the most commonly collected insect group accounting for 54% of the total capture. These data suggest that one reason green tree frogs were more abundant in canopy gaps was the increased availability of prey and that small canopy gaps provide early successional habitats that are beneficial to green tree frog populations.

The traps were placed at the centers, edges, and in the forest adjacent to gaps of different sizes (0.13, 0.26, and 0.50 ha) and ages (1 and 7 yr old) during four sampling periods in 2001. Overall, the abundance and species richness of insect herbivores were greater at the centers of young gaps than at the edge of young gaps or in the forest surrounding young gaps. There were no differences in abundance or species richness among old gap locations (i.e., centers, edges, and forest), and we collected significantly more insects in young gaps than old gaps. The insect communities in old gaps were more similar to the forests surrounding them than young gap communities were to their respective forest locations, but the insect communities in the two forests locations (surrounding young and old gaps) had the highest percent similarity of all. Although both abundance and richness increased in the centers of young gaps with increasing gap size, these differences were not significant. We attribute the increased numbers of herbivorous insects to the greater abundance of herbaceous plants available in young gaps.

In a period of 27 wk, >90,000 males were captured on sticky traps in the three locations in Key Biscayne, FL. Our experimental results showed that a laboratory-prepared (R)-lavandulyl (S)-2-methylbutanoate and (R)-maconelliyl (S)-2-methylbutanoate blend in a ratio of 1:5 on a rubber septum was attractive to males at concentration as low as 0.1 mu g per trap. Male M. hirsutus captures were not significantly different from traps baited with 1- or 10- mu g doses, but 0.1- and 100- mu g doses captured significantly fewer males. Some of the unnatural stereoisomers of the pheromone antagonized attraction. The alcohols, which could be detected in virgin female's volatiles, also exhibited a repulsive effect. Rubber septum lures baited with 1- and 10- mu g doses of the synthetic pheromone remained active for at least 21 wk under field conditions. Monitoring of adult flight activity with a 1- mu g dose of synthetic pheromone indicated there were multiple generations during the tested period of 8 July 2003 to 12 January 2004.

Eight aminoglycoside resistance genes were detected using PCR, most frequently ant(6)-Ia and aac(6')-Ii from Enterococcus faecium. Twenty-four per cent (45/187) of total high-level aminoglycoside-resistant isolates and 26% (4/15) of isolates resistant to high levels of all three antimicrobials were negative for all genes tested. These data suggest that enterococci isolated from swine contain diverse and possibly unidentified aminoglycoside resistance genes.

Saline and brackish water resources, marginal lands and plants capable of growing and producing an economic crop under the harsh conditions of the Arabian Peninsula, are abundant and expected to alleviate the mounting pressures on fresh water resources and prime agricultural lands. There is a need to demonstrate the value of saline water resources for the production of environmentally and economically useful plants and crops and to transfer the results to national research services and communities in the Arabian Peninsula. A regional strategy is needed to utilize the rapid advances in the use of saline water for irrigation, including development of improved irrigation systems, water management, control of salinity in root zone, and utilization of genetic resources of salt tolerant plants and halophytes. An integrated and holistic approach that reflects local and regional ecosystems' relationships is proposed. It addresses the long-term sustainability of saline agriculture and aims at developing decision-support systems to further focus attention on gaps in existing knowledge and provides flexible and efficient means for evaluating alternative options in saline agricultural production in the Arabian Peninsula.

To date, no multipurpose agricultural water quality model has seepage zones incorporated into its process-level representations. We chose to test two widely used models of agricultural water quality, the Groundwater Loading Effects of Agricultural Management Systems (GLEAMS) and the Root Zone Water Quality Model (RZWQM), by seeing how well each predicted solution pesticide concentration and loss in surface runoff from two agricultural fields: one with and one without seepage zones. Daily simulated atrazine and metolachlor concentration and loss in surface runoff from both calibrated and default (or non-calibrated) GLEAMS and RZWQM were compared with three years of measured data from the two fields. The results of the study show that GLEAMS and RZWQM using default input parameters were not capable of predicting atrazine and metolachlor concentration and loss in surface runoff from the fields with and without seepage zones (modeling efficiency 0.52, index of agreement >0.83, and modeling efficiency >0.53) and can be used for assessing the effects of seepage zones on pesticide loss in surface runoff from agricultural fields.

The lack of correlation between CLIGEN-generated storm variables may limit those models' abilities to predict surface runoff and soil erosion. The objectives of this study were to: (1) test a distribution-free method for inducing desired rank correlation between generated storm variables, and (2) compare WEPP-predicted runoff and soil loss using measured vs. variously generated storm patterns on eight U.S. sites. Four climate files containing four storm patterns (measured, original uncorrelated CLIGEN output, correlated CLIGEN output, and correlated output with exponentially generated storm durations), along with measured soil, slope, and crop management on each site, were used as input to WEPP. The distribution-free approach was simple to use and capable of inducing desired rank correlation between storm depth and duration and consequently between storm depth and relative peak intensity. Original CLIGEN output after inducing desired correlation considerably improved WEPP runoff and soil loss predictions on most sites where strong correlation between storm depth and duration existed. On average, the relative errors averaged over all sites were reduced from 15.0% to 4.6% for runoff prediction and from 11.1% to 1.5% for soil loss prediction. The use of exponentially distributed storm duration, compared with the original CLIGEN output, doubled the overall relative error for soil loss prediction due to the undesirable alteration of relative peak intensity estimates. Overall results indicate that for better runoff and soil loss prediction, correlated CLIGEN output should be used on sites where strong correlation between storm depth and duration exists.

The objectives of this study were to improve the stochastic generation of wind speed and direction and to update the wind statistics used by the generator with statistics derived from more recent, quality-controlled data for the 48 contiguous states of the U.S. Erosive wind power density (WPD) was chosen to evaluate how well wind is generated, since it is proportional to sediment transport by wind. It is important that WPD calculated from stochastically generated data (WPD sub(g)) closely reproduces WPD calculated from the underlying measured data (WPD sub(m)). The commonly used two-parameter Weibull model did not fit wind speed distributions well enough for application in wind erosion models. WPD sub(g) deviated more than 20% from WPD sub(m), for 168 out of the 332 stations having WPD sub(m) > 5 W m super(-2). Fitting the model to the high wind speeds only, with the expectation of a better curve fit, resulted in some generated wind speeds exceeding 100 m s super(-1), which is unacceptable. A more direct method uses the wind speed distributions themselves instead of the Weibull model that describes them. Wind speeds are then generated directly from the distributions using linear interpolation between data points. With this more robust direct approach, there was only one station (down from 168 stations) where WPD sub(g) deviated more than 20% from WPD sub(m). The direct method of wind speed generation reproduces wind speeds more accurately than the Weibull model, which is important for wind erosion prediction and may be important for other applications as well.

Follow-on studies in economics were designed to improve understanding of aspects of the competitiveness of the Alaska forest sector, links between Alaska timber markets and other markets as evident in prices, and the relationship between resource allocation decisions and economic conditions in communities and the region. Analysis of the role of recreation and tourism in the regional economy was added to the topics addressed, based on early results of work to describe economic dynamics. Comparisons are undertaken to evaluate the economic changes taking place in southeast Alaska, to analyze the sources of these changes, and to determine if and why they differ from the changes taking place at larger scales and those occurring in a similar rural and resource-abundant region. Divergent views regarding the current role of the Tongass in the regional economy are summarized and assessed by using contemporary evidence. A variety of factors contribute to comparative and competitive disadvantages for the forest products sector in southeast Alaska. Alaska product and log markets are effectively integrated with other markets supplied by producers in British Columbia and the Pacific Northwest. Empirical evidence suggests the need to re-examine assumptions regarding the relation between changes in "basic" sector activities and employment (such as timber harvesting and wood products manufacturing) and "nonbasic" (or support sector) employment in the rural communities of southeast Alaska. Many of the changes occurring in the economy of rural southeast Alaska are driven by changes in the international markets in which Alaskan products compete, and are largely independent of Tongass forest management. Unearned income and tourism have replaced resource-extractive industries as the principal sources of income growth in the region. The contribution of the Tongass National Forest to the regional economy has become more complex and difficult to quantify. Forest management policies that enhance the comparative advantages the region enjoys in providing both tourism opportunities and quality of life attributes will aid communities in maintaining and expanding their economic opportunities.

SWAT performed better than SMDR in simulating daily streamflows over the four-year simulation period (Nash-Sutcliffe coefficient: SWAT, 0.62; SMDR, 0.33). Both models varied stream-flow simulations seasonally as precipitation and watershed conditions varied. However, levels of agreement between simulated and observed flows were not consistent over seasons. SMDR, a variable source area based model, needs further improvement in model formulations to simulate large peak flows as observed. SWAT simulations matched the majority of observed peak flow events. SMDR overpredicted annual flow volumes, while SWAT underpredicted the same. Neither model routes runoff over the landscape to water bodies, which is critical to surface transport of phosphorus. SMDR representation of the watershed as grids may allow targeted management of phosphorus sources. SWAT representation of fields as hydrologic response units (HRUs) does not allow such targeted management.

This usage is based on misconceptions about the meaning of the runoff value that the method computes, which is a likely fundamental cause of uncertainty in subsequent erosion and pollutant loading predictions dependent on this value. As a result, there are some major limitations on the conclusions and decisions about the effects of management practices on water quality that can be supported with current nonpoint source water quality models. They also cannot supply the detailed quantitative and spatial information needed to address emerging issues. A key prerequisite for improving model predictions is to improve the hydrologic algorithms contained within them. The use of the curve number method is still appropriate for flood hydrograph engineering applications, but more physically based algorithms that simulate all streamflow generating processes are needed for nonpoint source water quality modeling. Spatially distributed hydrologic modeling has tremendous potential in achieving this goal.

AN - 67518370; 15769182 AB - A dioxin-contaminated mineral supplement was used to study the bioaccumulation and elimination of dioxins in two dairy cows. The supplement was mixed into the total maintenance ration and fed to the cows for 40 days after which unfortified diets were fed for 40 additional days. Dioxins and coplanar polychlorinated biphenyls (PCBs) were measured twice a week in the milk and in selected tissues of the cows, one at death (day 10 of withdrawal) and one at slaughter (day 40 of withdrawal). The dioxins and PCBs were readily transferred into the milk, and at steady state, total toxic equivalents were concentrated 6-fold into the milk fat from the diet. Bioaccumulation was inversely related to chlorination number. The elimination of dioxins and PCBs in milk was biphasic. With the exception of 1,2,3,4,6,7,8-heptachlorodioxin and both octachlorinated congeners, dioxin and furan half-lives in milk were approximately 3-5 days for the alpha-phase and 35-50 days for the beta-phase. PCB-169 had a longer half-life: 11 (alpha) and 200 days (beta). When milk and feed samples from Minnesota farms that had used similar contaminated mineral supplements were analyzed, no elevated dioxin levels were found in milk. It appeared that although the dioxins from the mineral supplements have the potential to bioaccumulate, dilution into the total diet was sufficient to prevent a significant rise in the dioxin concentrations in the milk at these farms.

AN - 67515800; 15769181 AB - Castor oil is the only commercial source of ricinoleic acid and has numerous industrial applications. Among the factors limiting domestic production of castor oil is the presence of the toxin ricin and its less toxic homologue Ricinus communis agglutinin (RCA) in seeds. Although the sequences of ricin and RCA genes are known, their transcriptional expression patterns have not been distinguished due to their high degree of sequence similarity. As the information is critical for assessing success in developing a ricin-free castor crop using genetic silencing, we have designed a gene specific reverse transcription-polymerase chain reaction (RT-PCR) assay to examine the expression of the ricin and RCA genes in developing seeds. The results show that the ricin and RCA mRNA are highly abundant in seeds during the development of endosperm, and the expression pattern is similar to that observed in the Northern analysis. The RT-PCR results can be confirmed by a simple RT-PCR-based restriction fragment analysis.

6198518 AB - There have been several proposals to evaluate potential runoff in center pivot irrigation, through the integration of time varying infiltration-precipitation rate curves, involving complex iterative procedures. Some methods use empirical infiltration functions, such as the Kostiakov equation. Others use physically based infiltration functions, such as the Green-Ampt equation. Another option is to use the Richards equation, describing the one-dimensional vertical infiltration of water into the soil for a specified irrigation event. This equation is generally accepted to provide a basis for comparison between other runoff estimation methods.[P.B. Luz, J.C. Martins, M.C. Goncalves, Reliable estimate of runoff in center pivot irrigation: statistical approach, in: Proceedings of the 16 Congress Mondial de Science du Sol, Poster 2-658, ISSS, Montpellier, France, August 19-25, 1998, pp. 577-593], developed a conceptual method of statistical nature, to estimate potential runoff in center pivot irrigation, comprising regression equations built with runoff results from a simulation computer model using the Richards equation. The procedure to simulate runoff involved a wide set of data related to water retention parameters and soil texture [W.J. Rawls, D.L. Brakensiek, Estimation of soil water retention and hydraulic properties, in: H.J. Morel-Seytoux (Ed.), Unsaturated Flow in Hydrologic Modeling, Theory and Practice, Kluwer Academic Publishers, Dordrecht, 1989, pp. 275-300], and water application. Such regression equations present a dependent variable, defined as an index of four parameters, related to the center pivot irrigation and to the soil-water system evaluation. The method had unacceptable results when a crust developed on the soil surface. Therefore, the objective of this study was to redefine the index, establishing new parameter coefficients with a trial and error approach. The model efficiency (similar to the coefficient of determination, r super(2)) ranged from 90 to 98%, showing the results are in good agreement to those computed by Richards equation, exhibiting a strong predictive value.

Most yeasts, including industrial strains, are susceptible to these inhibitory compounds, especially when multiple inhibitors are present. Additional detoxification steps add cost and complexity to the process and generate additional waste products. To promote efficient bioethanol production, we studied the mechanisms of stress tolerance, particularly to fermentation inhibitors such as furfural and HMF. We recently reported a metabolite of 2,5-bis-hydroxymethylfuran as a conversion product of HMF and characterized a dose-dependent response of ethanologenic yeasts to inhibitors. In this study, we present newly adapted strains that demonstrated higher levels of tolerance to furfural and HMF. Saccharomyces cerevisiae 307-12H60 and 307-12H120 and Pichia stipitis 307 10H60 showed enhanced biotransformation ability to reduce HMF to 2,5-bis-hydroxymethylfuran at 30 and 60 mM, and S. cerevisiae 307-12-F40 converted furfural into furfuryl alcohol at significantly higher rates compared to the parental strains. Strains of S. cerevisiae converted 100% of HMF at 60 mM and S. cerevisiae 307-12-F40 converted 100% of furfural into furfuryl alcohol at 30 mM. The results of this study suggest a possible in situ detoxification of the inhibitors by using more inhibitor-tolerant yeast strains for bioethanol fermentation. The development of such tolerant strains provided a basis and useful materials for further studies on the mechanisms of stress tolerance.

The extraction was carried out with ethyl acetate and an on-line extraction method applying an acetone-dichloromethane mixture. The extracts were cleaned up with SX-3 gel, an adsorbent mixture of active carbon, magnesia, and diatomaceous earth, and on silica micro cartridges. The Rf values of 118 pesticides were tested in eleven elution systems with UV, and eight biotest methods and chemical detection reagents. Cabbage, green peas, orange, and tomatoes were selected as representative sample matrices for fruits and vegetables, while maize, rice, and wheat represented cereal grains. As an internal quality control measure, marker compounds were applied on each plate to verify the proper elution and detection conditions. The Rf values varied in the different elution systems. The best separation (widest Rf range) was achieved with silica gel (SG)--ethyl acetate (0.05-0.7), SG--benzene, (0.02-0.7) and reverse phase RP-18 F-254S layer with acetone: methanol: water/30:30:30 (v/v) (0.1-0.8). The relative standard deviation of Rf values (CVRf) within laboratory reproducibility was generally less than 20%, except below 0.2 Rf, where the CVRf rapidly increased with decreasing Rf values. The fungi spore inhibition, chloroplast inhibition, and enzyme inhibition were found most suitable for detection of pesticides primarily for confirming their identity or screening for known substances. Their use for determination of pesticide residues in samples of unknown origin is not recommended.

Four short- season hybrids developed for production at [=>] 40 N latitude and two hybrids adapted to the Midsouth USA were grown at Stoneville, MS (3326' N, 9055' W), in 2002 and 2003 using N fertility treatments of 112 kg N ha super(-1) preplant, 224 kg N ha super(-1) preplant, or 112 kg N ha super(-1) preplant + 112 kg N ha super(-1) side- dress at growth stage V6 (six leaves). Growing degree units at 10 base temperature required for growth stages R1 (silking) and R6 (physiological maturity) of the four short-season hybrids were 50 and 100 units greater, respectively, than when grown in their adapted environments. Yields of two of the short-season hybrids compared well with the adapted hybrids. Kernel weights and grain bulk density differed among hybrids but were not below levels subject to dockage. Aflatoxin and fumonisin levels were higher in 2002 than 2003. Three of the short-season hybrids did have aflatoxin levels in 2002 at least three times greater than the other three hybrids. Plots receiving 224 kg N ha super(- 1) preplant yielded more than the other N fertility treatments. Kernel weights were 10 mg greater for the higher N fertility treatments. Nitrogen fertility had no effect on mycotoxins. Short-season hybrids need to be individually evaluated for production potential in the lower Mississippi River valley.

AN - 69058070; 16396350 AB - Most aspergilli that produce aflatoxin are members of Aspergillus section Flavi, however isolates of several Aspergillus species not closely related to section Flavi also have been found to produce aflatoxin. Two of the species, Aspergillus ochraceoroseus and an undescribed Aspergillus species SRRC 1468, are morphologically similar to members of Aspergillus section Circumdati. The other species have Emericella teleomorphs (Em. astellata and an undescribed Emericella species SRRC 2520) and are morphologically distinctive in having ascospores with large flanges. All these aflatoxin-producing isolates were from tropical zones near oceans, and none of them grew on artificial media at 37 C. Aflatoxins and sterigmatocystin production were quantified by high-pressure liquid chromatography (HPLC) and confirmed by HPLC-mass spectrometry (LC-MS) detection. Phylogenetic analyses were conducted on these four species using A. parasiticus and Em. nidulans, (which produce aflatoxin and the aflatoxin precursor sterigmatocystin, respectively) for comparison. Two aflatoxin/sterigmatocystin biosynthesis genes and the beta tubulin gene were used in the analyses. Results showed that of the new aflatoxin-producers, Aspergillus SRRC 1468 forms a strongly supported clade with A. ochraceoroseus as does Emericella SRRC 2520 with Em. astellata SRRC 503 and 512.

AN - 67919447; 15948582 AB - Using plants to extract excess nitrate from soil is important in protecting against eutrophication of standing water, hypoxic conditions in lakes and oceans, or elevated nitrate concentrations in domestic water supplies Global climate change issues have raised new concerns about nitrogen (N) management as it relates to crop production even though there may not be an immediate threat to water quality. Carbon dioxide (CO2) emissions are frequently considered the primary cause of global climate change, but under anaerobic conditions, animals can contribute by expelling methane (CH4) as do soil microbes. In terms of the potential for global climate change, CH4 is approximately 25 times more harmful than CO2. This differential effect is minuscule compared to when nitrous oxide (N2O) is released into the atmosphere because it is approximately 300 times more harmful than CO2. N2O losses from soil have been positively correlated with residual N (nitrate, NO3-) concentrations in soil. It stands to reason that phytoremediation via nitrate scavenger crops is one approach to help protect air quality, as well as soil and water quality. Winter wheat was inserted into a seed corn/soybean rotation to utilize soil nitrate and thereby reduce the potential for nitrate leaching and N2O emissions. The net effect of the 2001-2003 relay cropping sequence was to produce three crops in two years, scavenge 130 kg N/ha from the root zone, produce an extra 2 Mg residue/ha, and increase producer profitability by approximately 250 dollars/ha.

AN - 67918586; 15948583 AB - Two strategies of phytoextraction have been shown to have promise for practical soil remediation: domestication of natural hyperaccumulators and bioengineering plants with the genes that allow natural hyperaccumulators to achieve useful phytoextraction. Because different elements have different value, some can be phytomined for profit and others can be phytoremediated at lower cost than soil removal and replacement. Ni phytoextraction from contaminated or mineralized soils offers economic return greater than producing most crops, especially when considering the low fertility or phytotoxicity of Ni rich soils. Only soils that require remediation based on risk assessment will comprise the market for phytoremediation. Improved risk assessment has indicated that most Zn + Cd contaminated soils will not require Cd phytoextraction because the Zn limits practical risk from soil Cd. But rice and tobacco, and foods grown on soils with Cd contamination without corresponding 100-fold greater Zn contamination, allow Cd to readily enter food plants and diets. Clear evidence of human renal tubular dysfunction from soil Cd has only been obtained for subsistence rice farm families in Asia. Because of historic metal mining and smelting, Zn + Cd contaminated rice soils have been found in Japan, China, Korea, Vietnam and Thailand. Phytoextraction using southern France populations of Thlaspi caerulescens appears to be the only practical method to alleviate Cd risk without soil removal and replacement. The southern France plants accumulate 10-20-fold higher Cd in shoots than most T. caerulescens populations such as those from Belgium and the UK. Addition of fertilizers to maximize yield does not reduce Cd concentration in shoots; and soil management promotes annual Cd removal. The value of Cd in the plants is low, so the remediation service must pay the costs of Cd phytoextraction plus profits to the parties who conduct phytoextraction. Some other plants have been studied for Cd phytoextraction, but annual removals are much lower than the best T. caerulescens. Improved cultivars with higher yields and retaining this remarkable Cd phytoextraction potential are being bred using normal plant breeding techniques. JF - Zeitschrift fur Naturforschung.

AN - 67792191; 15859069 AB - The Calf Antibiotic and Sulfonamide Test (CAST), a microbial inhibition screening test, was developed for detecting antibiotics and sulfonamides in bob veal calf carcasses. The test uses Bacillus megaterium ATCC 9885 as the indicator organism and Mueller Hinton agar as the growth medium. Compared to Swab Test on Premises (STOP), developed in 1970, this screening test has higher sensitivity and the ability to detect a wider range of veterinary antimicrobial residual drugs, particularly sulfonamides, at lower concentrations. Carcasses that are tested with CAST and suspected of containing chemical residue above tolerance level are retained for confirmation. Disposition of these carcasses are determined upon laboratory result. Routine testing of bob veal calves with CAST allowed the Food Safety and Inspection Service to release most calf carcasses within 24 h post-slaughter, thus conserving shipping and handling resources. However, changes in the regulation in 1990 dictate that disposition of carcasses found to contain violative levels of sulfonamide residues should be based on laboratory findings. The analysis of the data for the years 1990-1994 and 1998 indicate that the use of CAST over the years was significant, and had a direct impact on reduction of residue violations in veal carcasses. With the use of CAST, potentially harmful antimicrobial chemicals entering the human food chain through veal meat have been minimized.

AN - 67791698; 15859091 AB - Two rapid methods of sample preparation and analysis of fatty foods (e.g., milk, eggs, and avocado) were evaluated and compared for 32 pesticide residues representing a wide range of physicochemical properties. One method, dubbed the quick, easy, cheap, effective, rugged, and safe (QuEChERS) method for pesticide residue analysis, entailed extraction of 15 g sample with 15 mL acetonitrile (MeCN) containing 1% acetic acid followed by addition of 6 g anhydrous magnesium sulfate and 1.5 g sodium acetate. After centrifugation, 1 mL of the buffered MeCN extract underwent a cleanup step (in a technique known as dispersive solid-phase extraction) using 50 mg each of C18 and primary secondary amine sorbents plus 150 mg MgSO4. The second method incorporated a form of matrix solid-phase dispersion (MSPD), in which 0.5 g sample plus 2 g C18 and 2 g anhydrous sodium sulfate was mixed in a mortar and pestle and added above a 2 g Florisil column on a vacuum manifold. Then, 5 x 2 mL MeCN was used to elute the pesticide analytes from the sample into a collection tube, and the extract was concentrated to 0.5 mL by evaporation. Extracts in both methods were analyzed concurrently by gas chromatography/mass spectrometry and liquid chromatography/tandem mass spectrometry. The recoveries of semi-polar and polar pesticides were typically 100% in both methods (except that basic pesticides, such as thiabendazole and imazalil, were not recovered in the MSPD method), but recovery of nonpolar pesticides decreased as fat content of the sample increased. This trend was more pronounced in the QuEChERS method, in which case the most lipophilic analyte tested, hexachlorobenzene, gave 27 +/- 1% recovery (n=6) in avocado (15% fat) with a<10 ng/g limit of quantitation.

AN - 67791655; 15859089 AB - Validation experiments were conducted of a simple, fast, and inexpensive method for the determination of 229 pesticides fortified at 10-100 ng/g in lettuce and orange matrixes. The method is known as the quick, easy, cheap, effective, rugged, and safe (QuEChERS) method for pesticide residues in foods. The procedure involved the extraction of a 15 g sample with 15 mL acetonitrile, followed by a liquid-liquid partitioning step performed by adding 6 g anhydrous MgSO4 plus 1.5 g NaCl. After centrifugation, the extract was decanted into a tube containing 300 mg primary secondary amine (PSA) sorbent plus 1.8 g anhydrous MgSO4, which constituted a cleanup procedure called dispersive solid-phase extraction (dispersive SPE). After a second shaking and centrifugation step, the acetonitrile extract was transferred to autosampler vials for concurrent analysis by gas chromatography/mass spectrometry with an ion trap instrument and liquid chromatography/tandem mass spectrometry with a triple quadrupole instrument using electrospray ionization. Each analytical method was designed to analyze 144 pesticides, with 59 targeted by both instruments. Recoveries for all but 11 of the analytes in at least one of the matrixes were between 70-120% (90-110% for 206 pesticides), and repeatabilities typically <10% were achieved for a wide range of fortified pesticides, including methamidophos, spinosad, imidacloprid, and imazalil. Dispersive SPE with PSA retained carboxylic acids (e.g., daminozide), and <50% recoveries were obtained for asulam, pyridate, dicofol, thiram, and chlorothalonil. Many actual samples and proficiency test samples were analyzed by the method, and the results compared favorably with those from traditional methods.

AN - 67788688; 15859090 AB - A modification that entails the use of buffering during extraction was made to further improve results for certain problematic pesticides (e.g., folpet, dichlofluanid, chlorothalonil, and pymetrozine) in a simple, fast, and inexpensive method for the determination of pesticides in produce. The method, known as the quick, easy, cheap, effective, rugged, and safe (QuEChERS) method for pesticide residues in foods, now involves the extraction of the sample with acetonitrile (MeCN) containing 1% acetic acid (HAc) and simultaneous liquid-liquid partitioning formed by adding anhydrous MgSO4 plus sodium acetate (NaAc). The extraction method is carried out by shaking a centrifuge tube which contains 1 mL of 1% HAc in MeCN plus 0.4 g anhydrous MgSO4 and 0.1 g anhydrous NaAc per g sample. The tube is then centrifuged, and a portion of the extract is transferred to a tube containing 50 mg primary secondary amine sorbent plus 150 mg anhydrous MgSO4/mL of extract. After a mixing and centrifugation step, the extract is transferred to autosampler vials for concurrent analysis by gas chromatography/mass spectrometry (GC/MS) and liquid chromatography/tandem mass spectrometry. Independent of the original sample pH, the use of buffering during the extraction yields pH 5 in the water phase, which increases recoveries of both acid- and base-sensitive pesticides. The method was evaluated for 32 diverse pesticides in different matrixes, and typical percent recoveries were 95 +/- 10, even for some problematic pesticides. Optional solvent exchange to toluene prior to GC/MS analysis was also evaluated, showing equally good results with the benefit of lower detection limits, but at the cost of more time, material, labor, and expense.

AN - 67788139; 15859070 AB - The Fast Antimicrobial Screen Test (FAST) is a simple and quick screening test developed to detect antibiotic and sulfonamide residues in food animal carcasses in slaughter establishments. This microbial inhibition test detects antimicrobials that are allowed to be used in food animals. It has the ability to detect these antimicrobials at or above the allowable limit in carcass kidney fluids in 6 h. Laboratory evaluations show that the lower limit of detection (LLD) of FAST and the Calf Antibiotic and Sulfa Test (CAST) for antibiotics tested was the same, but the LLD for sulfonamides of FAST was lower than the LLD of CAST. Compared with the Swab Test on Premises (STOP) developed in 1977, the LLD's of FAST for both antibiotics and sulfonamides were significantly better. Under field conditions, the sensitivity of FAST and CAST to antibiotic and sulfonamide residues in animal kidneys was not significantly different, but the time required by FAST was significantly lower than CAST (6 versus 18 h). Compared with the STOP, the sensitivity and the range of detection by FAST for all antimicrobials were significantly higher and the testing time was lower (18 versus 6 h).

AN - 67511344; 15765694 AB - Detection of apples contaminated with feces is a public health concern. We found that time-resolved imaging of apples artificially contaminated with feces allowed optimization of timing parameters for detection. Dairy feces were applied to Red Delicious and Golden Delicious apples. Laser-induced fluorescence responses were imaged by use of a gated intensified camera. We developed algorithms to automatically detect contamination iteratively by using one half of the apples and validated them by applying the optimized algorithms to the remaining apples. Results show that consideration of the timing of fluorescence responses to pulsed-laser excitation can enhance detection of feces on apples.

Impacts on greenhouse gases, odor compounds, nitrogen losses, and dust. AN - 67506648; 15758117 AB - Beef cattle feedlots face serious environmental challenges associated with manure management, including greenhouse gas, odor, NH3, and dust emissions. Conditions affecting emissions are poorly characterized, but likely relate to the variability of feedlot surface moisture and manure contents, which affect microbial processes. Odor compounds, greenhouse gases, nitrogen losses, and dust potential were monitored at six moisture contents (0.11, 0.25, 0.43, 0.67, 1.00, and 1.50 g H2O g(-1) dry matter [DM]) in three artificial feedlot soil mixtures containing 50, 250, and 750 g manure kg(-1) total (manure + soil) DM over a two-week period. Moisture addition produced three microbial metabolisms: inactive, aerobic, and fermentative at low, moderate, and high moisture, respectively. Manure content acted to modulate the effect of moisture and enhanced some microbial processes. Greenhouse gas (CO2, N2O, and CH4) emissions were dynamic at moderate to high moisture. Malodorous volatile fatty acid (VFA) compounds did not accumulate in any treatments, but their persistence and volatility varied depending on pH and aerobic metabolism. Starch was the dominant substrate fueling both aerobic and fermentative metabolism. Nitrogen losses were observed in all metabolically active treatments; however, there was evidence for limited microbial nitrogen uptake. Finally, potential dust production was observed below defined moisture thresholds, which were related to manure content of the soil. Managing feedlot surface moisture within a narrow moisture range (0.2-0.4 g H2O g(-1) DM) and minimizing the accumulation of manure produced the optimum conditions that minimized the environmental impact from cattle feedlot production.

AN - 67500027; 15752184 AB - Responses of host-seeking nymphs of the blacklegged tick, Ixodes scapularis Say and lone star tick, Amblyomma americanum (Linnaeus) (Acari: Ixodidae) to the repellents N,N-diethyl-3-methylbenzamide (deet) and (1S, 2'S)-2-methylpiperidinyl-3-cyclohexene-1-carboxamide (SS220) were studied using fingertip laboratory bioassays. Ethanol solutions of both compounds applied to the skin strongly repelled both species of ticks at 0.8 and 1.6 micromole of compound/cm2 skin. The ticks were also repelled when two layers of organdie cloth covered the portion of a finger treated with either deet or SS220. Gas chromatographic analyses of the outer layer of cloth that had covered skin treated with 1.6 micromole compound/cm2 skin revealed only 0.1 nmole SS220/cm2 cloth and 2.8 nmole deet/cm2 cloth. However, in bioassays in which a single layer of cloth was treated with a dose of deet or SS220 equivalent to the amount found in the outer layer of cloth, ticks were not repelled. Results unequivocally demonstrated that these ticks responded to the repellents in the vapour phase when repellent treated skin was covered with cloth to obviate tactile contact with them, and made it clear that the ticks detect the repellents by olfactory sensing. Heretofore, the mode of action of deet and SS220 was unclear.

AN - 67439818; 15660452 AB - Since transgenic, bromoxynil-resistant cotton and glufosinate-resistant canola were introduced in 1995, planting of transgenic herbicide-resistant crops has grown substantially, revolutionizing weed management where they have been available. Before 1995, several commercial herbicide-resistant crops were produced by biotechnology through selection for resistance in tissue culture. However, non-transgenic herbicide-resistant crops have had less commercial impact. Since the introduction of glyphosate-resistant soybean in 1996, and the subsequent introduction of other glyphosate-resistant crops, where available, they have taken a commanding share of the herbicide-resistant crop market, especially in soybean, cotton and canola. The high level of adoption of glyphosate-resistant crops by North American farmers has helped to significantly reduce the value of the remaining herbicide market. This has resulted in reduced investment in herbicide discovery, which may be problematic for addressing future weed-management problems. Introduction of herbicide-resistant crops that can be used with selective herbicides has apparently been hindered by the great success of glyphosate-resistant crops. Evolution of glyphosate-resistant weeds and movement of naturally resistant weed species into glyphosate-resistant crop fields will require increases in the use of other herbicides, but the speed with which these processes compromise the use of glyphosate alone is uncertain. The future of herbicide-resistant crops will be influenced by many factors, including alternative technologies, public opinion and weed resistance. Considering the relatively few recent approvals for field testing new herbicide-resistant crops and recent decisions not to grow glyphosate-resistant sugarbeet and wheat, the introduction and adoption of herbicide-resistant crops during the next 10 years is not likely to be as dramatic as in the past 10 years.

AN - 67438360; 15668922 AB - Hydrilla [Hydrilla verticillata (Lf) Royle] is one of the most serious invasive aquatic weed problems in the USA. This plant possesses numerous mechanisms of vegetative reproduction that enable it to spread very rapidly. Management of this weed has been achieved by the systemic treatment of water bodies with the herbicide fluridone. At least three dioecious fluridone-resistant biotypes of hydrilla with two- to fivefold higher resistance to the herbicide than the wild-type have been identified. Resistance is the result of one of three independent somatic mutations at the arginine 304 codon of the gene encoding phytoene desaturase, the molecular target site of fluridone. The specific activities of the three purified phytoene desaturase variants are similar to the wild-type enzyme. The appearance of these herbicide-resistant biotypes may jeopardize the ability to control the spread of this non-indigenous species to other water bodies in the southern USA. The objective of this paper is to provide general information about the biology and physiology of this aquatic weed in relation to its recent development of resistance to the herbicide fluridone, and to discuss how this discovery might lead to a new generation of herbicide-resistant crops.

The objective of this study was to evaluate the fertilizer value of dried algal biomass that had been grown using anaerobically digested dairy manure. Results from a flask study using two soils amended with algal biomass showed that 3% of total algal nitrogen (N) was present as plant available N at day 0. Approximately 33% of algal N was converted to plant available N within 21 days at 25 degree C in both soils. Levels of Mehlich-3 extractable phosphorus (P) in the two soils rose with increasing levels of algal amendment but were also influenced by existing soil P levels. Results from plant growth experiments showed that 20-day old cucumber and corn seedlings grown in algae-amended potting mix contained 15-20% of applied N, 46-60% of available N, and 38-60% of the applied P. Seedlings grown in algae-amended potting mixes were equivalent to those grown with comparable levels of fertilizer amended potting mixes with respect to seedling dry weight and nutrient content. These results suggest that dried algal biomass produced from treatment of anaerobically digested dairy manure can substitute for commercial fertilizers used for potting systems.

An oxidative detoxification mechanism was suspected to contribute to coumaphos resistance in this tick strain, as coumaphos bioassay with piperonyl butoxide (PBO) on larvae of this resistant strain resulted in enhanced coumaphos toxicity, while coumaphos assays with PBO resulted in reduced toxicity of coumaphos in a susceptible reference strain. In this study, we further analyzed the mechanism of oxidative metabolic detoxification with synergist bioassays of coroxon, the toxic metabolite of coumaphos, and the mechanism of target-site insensitivity with acetylcholinesterase (AChE) inhibition kinetics assays. Bioassays of coroxon with PBO resulted in synergism of coroxon toxicity in both the San Roman and the susceptible reference strains. The synergism ratio of PBO on coroxon in the resistant strain was 4.5 times that of the susceptible strain. The results suggested that the cytP450-based metabolic detoxification existed in both resistant and susceptible strains, but its activity was significantly enhanced in the resistant strain. Comparisons of AChE activity and inhibition kinetics by coroxon in both susceptible and resistant strains revealed that the resistant San Roman strain had an insensitive AChE, with a reduced phosphorylation rate, resulting in a reduced bimolecular reaction constant. These data indicate a mechanism of coumaphos resistance in the San Roman strain that involves both insensitive AChE and enhanced cytP450-based metabolic detoxification.

Gas chromatographic (GC) analysis of volatiles collected from feeding male or female beetles, or saltcedar foliage alone, showed two components produced almost exclusively by males. These compounds elicited responses from antennae of male and female beetles in GC-electroantennographic detection (EAD) analyses. The compounds were identified as (2E,4Z)-2,4-heptadienal (1) and (2E,4Z)-2,4-heptadien-1-ol (2) by GC-mass spectrometry (MS), and confirmed with authentic standards. The two compounds were also detected at trace levels from feeding females and foliage controls, but the amounts from feeding males were 8-40 times higher, typically 55-125 ng per day per male. The amounts of 1 and 2 in collections from females did not differ significantly from amounts collected from control foliage. In field trials, 2 as a single component was as attractive as a 1:1 blend of 1 and 2. Compound 1 as a single component was more attractive than controls, but much less attractive than 2 or the blend. Males and females were attracted in about equal numbers, indicating that this is an aggregation pheromone.

Sampling programs and methods of developing sampling programs for integrated pest management are not sufficient for site-specific weed management because more and different information is needed to make treatment maps than simply estimate average pest density. Sampling plans for site-specific weed management must provide information to map the weeds in the field but should be developed for the objective of prescribing spatially variable management. Weed scientists will be most successful at designing plans for site-specific weed management if they focus on this objective throughout the process of designing a sampling plan. They must also learn more about the spatial distribution and dynamics of weed populations and use that knowledge to identify cost-effective plans, recommend methods to make maps as well as collect data, and find ways to evaluate maps that reflect management to be prescribed from the map. Foremost, sampling must be thought of as an ongoing process over time that uses many types of information rather than a single event of collecting one type of information. Specifically, scientists will need to identify common characteristics rather than just differences of the spatial distribution of weeds among fields and species, recognize that map accuracy may be a poor indicator of the value of a sampling plan, and develop methods to use growers' knowledge of the distribution of weeds and past spatially variable management within a field for both making a map and recommending a sampling plan. The value of proposed methods for sampling and mapping must also be demonstrated or adoption of site-specific weed management might be limited to growers who enjoy using sophisticated technology.

Chlorophyll fluorescence was monitored as an indicator of photosynthetic efficiency, and measurement of reactive oxygen species (ROS) was performed using the ROS-sensitive probe 2',7'-dichlorodihydrofluorescein diacetate. The effects of the herbicide paraquat (a ROS generator) as well as ascorbate and alpha -tocopherol (ROS scavengers) on ROS formation by P. perornata were studied. Also, the effects of different concentrations of ascorbate, alpha -tocopherol, and the herbicide diuron on reducing the toxicity of the water-soluble anthraquinone derivative towards P. perornata were determined. Our results indicate that the water-soluble anthraquinone derivative does not inhibit photosynthetic electron transport directly, but does generate ROS at levels that may cause toxicity towards P. perornata.

The objectives of this study were to examine the efficacy of burning, grazing, and herbicide to reduce smooth brome production and cover while minimizing coincident detrimental effects on cool-season grasses in a reclaimed surface coal mine site. Concurrently, the project also investigated effects of microbial inoculation on respread topsoil subjected to long-term storage and associated effects on seeded cool-season grasses subjected to brome control treatments. Results indicated that grazing and burning were most effective after 2 years of treatment. Smooth brome biomass was lowest in reburned cells (mean plus or minus SE, 189 plus or minus 77 kg.ha super(-1)) followed by regrazed (294 plus or minus 129) compared to untreated cells (824 plus or minus 42) (P < 0.0001). Native grass production was highest in grazed cells (141 plus or minus 67 kg.ha super(-1)) followed by burning (104 plus or minus 41), herbicide (72 plus or minus 30), and untreated (30 plus or minus 27). Foliar cover response patterns were similar. Inoculation had little effect on microbial biomass and mycorrhizal infection. Retreated cells did show differences among months (P = 0.013) in 2000, and microbial carbon ranged from 0.07 plus or minus 0.01 mg/g in June to 0.12 plus or minus 0.01 in July and 0.12 plus or minus 0.01 in August, averaged across treatments. Root infection decreased as soil moisture declined. Results indicate grazing offers the greatest potential for controlling smooth brome without harming native, seeded grasses on reclaimed lands in northern mixed-prarie communities, and inoculation was unnecessary for enhancing seeded, cool-season grass growth.Original Abstract: La introduccion y subsecuente invasion del 'Smooth brome' (Bromus inermis Leyss.) en la comunidades de pastizal de zacates de estacion fria y caliente ha venido a ser problematico donde la presencia de las especies nativas es importante o mandatoria. Los objetivos de este estudio fueron examinar la eficacia de la quema, el apacentamiento y los herbicidas para reducir la produccion y cobertura del 'Smooth brome' minimizando los efectos perjudiciales colaterales sobre los zacates de estacion fria en un sitio en restauracion de una mina superficial de carbon. El proyecto tambien examino los efectos de la inoculacion microbiana sobre el suelo de la capa superficial esparcido en el sitio despues de un largo periodo de almacenamiento y los efectos asociados en zacates de estacion fria sembrados y sujetos a tratamientos de control de 'Smooth brome.' Los resultados indican que el apacentamiento y la quema fueron mas efectivos despues de dos anos de tratamiento. La menor biomasa de 'Smooth brome' se obtuvo en las areas re-quemadas (media plus or minus EE, 189 plus or minus 77 kg.ha super(-1)),seguida por las areas re-apacentadas (294 plus or minus 129 kg.ha super(-1)) comparados con las areas sin tratar (824 plus or minus 42 kg.ha super(-1))(P < 0.0001). La mayor produccion de biomasa de los zacates nativos se obtuvo en las areas apacentadas (141 plus or minus 67 kg.ha super(-1)), seguida por las areas quemadas, con aplicacion de herbicidas y sin tratar con 104 plus or minus 41, 72 plus or minus 30 y 30 plus or minus 27 kg.ha super(-1) respectivamente. Los patrones de respuesta de la cobertura foliar fueron similares. La inoculacion tuvo poco efecto en la biomasa microbiana y la infeccion de micorrizas. En el 2000, las areas re-tratatadas mostraron diferencias entre meses (P = 0.013) y el carbon microbiano, promediado entre tratamientos, vario de 0.07 plus or minus 0.01 mg/g en Junio a 0.12 plus or minus 0.01 en Julio y 0.12 plus or minus 0.01 en Agosto. La infeccion radical disminuyo conforme la humedad del suelo disminuyo. Los resultados indican que el apacentamiento ofrece el mayor potencial para controlar el 'Smooth brome' sin danar a los zacates nativos sembrados en sitios en restauracion de las comunidades de praderas mixtas del norte y la inoculacion fue innecesaria para mejorar el crecimiento de los zacates de estacion fria sembrados.

Microbial activity in aquifers is usually limited by substrate availability, and biobarriers stimulate microbial activity by providing a substrate; for these studies soybean oil was used. Water containing 10 mg L super(-1) selenite-Se was pumped through the biobarriers for 74 days and the amount present in the effluent monitored. The amounts remained high for the first 2 weeks of the study but then declined. From day 28 until the end of the study the amount of selenite-Se in the column effluents averaged 0.20 plus or minus 0.04 mg L super(-1), a decrease of approximately 98%. At the end of the study about half of the selenite-Se applied to the columns was recovered as immobilized selenium trapped by the biobarrier. This study suggests that biobarriers containing vegetable oil might be used as a process for removing selenite from contaminated groundwater.

Since V. destructor transfers pathogens to honeybees, it may be adaptive for bees to respond to mite infestation by upregulating their immune responses. Mites, however, may overcome the host's immune responses by suppressing them, which could facilitate the mite's ability to feed on hemolymph. A humoral immune response of bees parasitized by V. destructor may be detected by studying the expression levels of antibacterial peptides, such as abaecin and defensin, known to be immune-responsive. Expression levels for these two antibacterial peptides changed non-linearly with respect to the number of mites parasitizing honeybee pupae. Bees exposed to low or moderate number of mites had fewer immune-related transcripts than pupae that were never parasitized or pupae with high mite loads. Although many of the pupae tested indicated the presence of bacteria, no correlation with mite numbers or immune-response levels existed. All bees tested negative for acute paralysis and Kashmir bee viruses known to be vectored by V. destructor.

These methods provide powerful means for general screening of organisms actively producing and accumulating PHAs. The Southern blot hybridization method additionally allows the identification of potential PHA-producing microorganisms. Polymerase chain reaction (PCR)-based detection methods further afford rapid and sensitive means to screen for PHA biosynthesis genes. Specific PCR assays had been developed for the simultaneous or individual detection of the class II mcl-PHA synthase genes of Pseudomonas. The amplicons ( similar to 0.54 kb) can be directly sequenced or used as probes for hybridization studies. The sequence information can further be used to initiate chromosome walking for an eventual cloning of the complete PHA biosynthesis operon. In addition, the amplification pattern and sequence data can be used to differentiate subgroups of organisms, as demonstrated for P. corrugata and P. mediterranea. Other researchers reported PCR methods for the detection of scl-PHA synthase genes and those of Bacillus spp., thus greatly expanding the types of PHA synthase gene and the organisms that can be characterized by this approach. The vast sequence information obtainable through PCR based studies of various PHA synthase operons should facilitate the identification or construction of new PHA synthases capable of synthesizing novel PHAs.

Attempts to improve the vaccination process include numerous variations of individual shop-built vaccinators in use by the layer sector of the poultry industry. Each of these vaccinators has limitations that contribute to poor vaccinations. Major problems include the nonuniform speed of the applicator system and pressure fluctuations at the spray nozzles, which contribute to sporadic dispersion of the vaccine as the vaccinator is pushed or carried past the cages. A battery-powered, self-propelled, constant-speed vaccinator was designed and constructed that operates with constant nozzle pressure. In field use, this vaccinator has resulted in both labor savings (reduction of manpower from five to one to vaccinate 75,000 chickens) and time savings (from 45 min to 7.5 min/poultry house) as well as improved vaccination results (higher positive seroconversion rates) against the poultry pathogen Mycoplasma gallisepticum (MG), a bacterium associated with losses of 15.7 eggs /hen over a 45-wk laying period in MG-infected layers as compared with layers maintained free from infection with MG.Nota de Investigacion-Dispositivo de vacunacion por aerosol de propulsion autonoma y velocidad constante para ser empleado en explotaciones de ponedoras comerciales.La vacunacion de ponedoras comerciales es una labor intensiva que resulta con frecuencia en indices pobres de conversion serologica, la cual a su vez, se correlaciona generalmente con una disminucion de la uniformidad y el desempeno del lote. Diferentes intentos para mejorar los procesos de vacunacion incluyen numerosas variaciones de dispositivos de vacunacion construidos actualmente y en uso por el sector avicola de ponedoras comerciales. Cada uno de estos dispositivos posee limitantes que contribuyen a una pobre vacunacion. Los problemas principales incluyen la velocidad desuniforme del sistema de aplicacion y fluctuaciones en la presion de las boquillas de aspersion que contribuyen a una dispersion esporadica de la vacuna a medida que el dispositivo de vacunacion es desplazado a traves de las jaulas. Se diseno y construyo un dispositivo de vacunacion activado mediante bateria, de propulsion autonoma y velocidad constante que opera con una presion constante a nivel de las boquillas. En el campo, este dispositivo de vacunacion ha logrado una reduccion de los costos de operacion (reduccion en mano de obra de cinco a una persona para vacunar 75,000 ponedoras comerciales), ahorro de tiempo (de 45 minutos a 7.5 minutos por galpon) y mejores resultados de vacunacion (incremento en los indices positivos de conversion serologica) contra el patogeno aviar Mycoplasma gallisepticum (MG), bacteria asociada con perdidas de 15.7 huevos por ponedora en un periodo de 45 semanas en ponedoras comerciales infectadas en comparacion con ponedoras comerciales libres de la infeccion con MG.Abbreviations: MG = Mycoplasma gallisepticum JF - Avian Diseases AU - Branton, S L AU - Roush, W B AU - Lott, B D AU - Evans, J D AU - Dozier, WA AU - Collier, S D AU - Bearson, SMD AU - Bearson, B L AU - Pharr, G T AD - USDA, Agricultural Research Service, Poultry Research Unit, Mississippi State, MS 39762 Y1 - 2005/03// PY - 2005 DA - Mar 2005 SP - 147 EP - 151 PB - American Association of Avian Pathologists VL - 49 IS - 1 SN - 0005-2086, 0005-2086 KW - Microbiology Abstracts B: Bacteriology KW - Houses KW - Aerosols KW - Poultry KW - Seroconversion KW - Vaccines KW - Pathogens KW - Infection KW - Pressure KW - Vaccination KW - Mycoplasma gallisepticum KW - Eggs KW - J 02350:Immunology UR - http://libproxy.lib.unc.edu/login?url=http://search.proquest.com/docview/19821895?accountid=14244 L2 - http://vb3lk7eb4t.search.serialssolutions.com/?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQ%3Amicrobiologyb&rft_val_fmt=info:ofi/fmt:kev:mtx:journal&rft.genre=article&rft.jtitle=Avian+Diseases&rft.atitle=A+Self-Propelled%2C+Constant-Speed+Spray+Vaccinator+for+Commercial+Layer+Chickens&rft.au=Branton%2C+S+L%3BRoush%2C+W+B%3BLott%2C+B+D%3BEvans%2C+J+D%3BDozier%2C+WA%3BCollier%2C+S+D%3BBearson%2C+SMD%3BBearson%2C+B+L%3BPharr%2C+G+T&rft.aulast=Branton&rft.aufirst=S&rft.date=2005-03-01&rft.volume=49&rft.issue=1&rft.spage=147&rft.isbn=&rft.btitle=&rft.title=Avian+Diseases&rft.issn=00052086&rft_id=info:doi/10.1043%2F0005-2086%282005%29492.0.CO%3B2 L2 - http://journals.allenpress.com/jrnlserv/?request=get-abstract&issn=0005-2086&volume=49&page=147 LA - English DB - ProQuest Environmental Science Collection N1 - Date revised - 2009-05-01 N1 - Last updated - 2011-12-14 N1 - SubjectsTermNotLitGenreText - Mycoplasma gallisepticum; Vaccination; Poultry; Pressure; Seroconversion; Aerosols; Pathogens; Vaccines; Eggs; Infection; Houses DO - http://dx.doi.org/10.1043/0005-2086(2005)49<147:ASCSVF>2.0.CO;2 ER - TY - JOUR T1 - Cattle Feedlot Soil Moisture and Manure Content -- II. Impact on Escherichia coli O157 AN - 19771696; 6495109 AB - The moisture and manure contents of soils at cattle feedlot surfaces vary spatiotemporally and likely are important factors in the persistence of Escherichia coli O157 in these soils. The impacts of water content (0.11- 1.50 g H sub(2)O g super(-1) dry feedlot surface material [FSM]) and manure level (5, 25, and 75% dry manure in dry FSM) on E. coli O157:H7 in feedlot soils were evaluated. Generally, E. coli O157:H7 numbers either persisted or increased at all but the lowest moisture levels examined. Manure content modulated the effect of water on E. coli growth; for example, at water content of 0.43 g H sub(2)O g super(-1) dry FSM and 25% manure, E. coli O157:H7 increased by 2 log sub(10) colony forming units (CFU) g super(-1) dry FSM in 3 d, while at 0.43 g H sub(2)O g super(-1) dry FSM and 75% manure, populations remained stable over 14 d. Escherichia coli and coliform populations responded similarly. In a second study, the impacts of cycling moisture levels and different drying rates on naturally occurring E. coli O157 in feedlot soils were examined. Low initial levels of E. coli O157 were reduced to below enumerable levels by 21 d, but indigenous E. coli populations persisted at >2.50 log sub(10) CFU g super(-1) dry FSM up to 133 d. We conclude that E. coli O157 can persist and may even grow in feedlot soils, over a wide range of water and manure contents. Further investigations are needed to determine if these variables can be manipulated to reduce this pathogen in cattle and the feedlot environment.

Pigs were allotted to four treatments including: 1) nonchallenged control (NONC); 2) challenged control (CHAC); 3) 7% (as-fed basis) spray-dried plasma (SDP); and 4) 2% (as-fed basis) glutamine (GLN). On d 11 after weaning, all pigs were fitted with an indwelling jugular catheter. On d 12 after weaning, pigs in the CHAC, SDP, and GLN groups were orally challenged with skim milk E. coli K88 super(+) culture, whereas pigs in the NONC group were orally inoculated with sterilized skim milk. Rectal temperatures and fecal diarrheic scores were recorded and blood samples collected at 0 (baseline), 6, 12, 24, 36, and 48 h after the challenge for serum hormone and cytokine measurements. At 48 h postchallenge, all pigs were killed for evaluation of small intestinal morphology. There was no effect of feeding SDP or GLN on growth performance during the 11-d prechallenge period (P = 0.13). At 48 h after the challenge, CHAC pigs had decreased ADG (P = 0.08) and G:F (P = 0.07) compared with the NONC pigs; however, SDP and NONC pigs did not differ in G:F, and GLN and NONC pigs did not differ for ADG and G:F. At 6, 36, and 48 h after the challenge, CHAC, SDP, and GLN pigs had increased rectal temperature relative to the baseline (P = 0.09). At 12 and 36 h after the challenge, CHAC pigs had the highest incidence of diarrhea among treatments (P = 0.08). Serum IL-6 and ACTH were not affected by treatment or time after E. coli challenge (P = 0.11). In proximal, midjejunum, and ileum, CHAC pigs had greater villous atrophy and intestinal morphology disruption than NONC pigs (P < 0.01), whereas SDP and GLN pigs had mitigated villous atrophy and intestinal morphology impairment after E. coli challenge. Pigs in the SDP had the lowest GH at 12 h and the greatest GH at 36 h after the challenge among treatments (P = 0.08). Pigs in the NONC had the highest IGF-1 at 12 and 36 h postchallenge (P < 0.04). These results indicate that feeding glutamine has beneficial effects in alleviating growth depression of E. coli K88 super(+)-challenged pigs, mainly via maintaining intestinal morphology and function, and/or possibly via modulating the somatotrophic axis.

Broad-scope problems associated with developing sustainable cropping systems are how to choose and sequence crops in cropping systems. Our objectives were twofold: (i) evaluate impacts of crop sequencing on precipitation use and (ii) show how crop sequencing can accentuate synergistic interactions among crops. Crop-fallow systems that developed in the Great Plains resulted in precipitation storage efficiencies of about 20% in the early 1930s to about 40% in the late 1980s. Integrated crop-livestock systems have been developed in the southern Great Plains to take advantage of bimodal annual precipitation pattern to produce high quality pigeonpea [Cajanus cajan (L.) Millsp.] forage during the noncrop period between winter wheat (Triticum aestivum L.) harvest and seeding. Pigeonpea can be grown after a mid-June winter wheat harvest since pigeonpea uses precipitation received from wheat harvest to late September and pigeonpea has a root system that allows it to use soil water below the effective rooting depth of wheat. In the central Great Plains, water-use efficiency of winter wheat was improved 18 to 56% by including broadleaf crop in a grass-based rotation. Cropping systems in the northern Great Plains tend to be more diverse, and research at Mandan, ND, suggests that seed yield of flax (Linum usitatissium L.) can be tripled with a safflower (Carthamus tinctorius L.)- flax crop sequence vs. a flax-flax crop sequence. Great Plains cropping systems of the future will not only need to take advantage of crop sequences through synergism, but also take advantage of the interactions associated with diversity in space (polyculture).

The CAs play an important role in insect physiology because of their production of the juvenile hormones (JHs), i.e., key hormones involved in development and reproduction. We found that the P. bioculatus CA-CC complex is present in two distinct morphological forms, the more frequently observed complex containing one 'fused' CA between two CCs and the more rarely observed complex having one CA laterally attached to each CC. These complexes were tested for their ability to synthesize JH-like compounds. We found that the primary lipophilic compound synthesized by the CA-CCs migrated differently from JH III (a JH found in numerous insect species) when subjected to thin-layer chromatography. Furthermore, the synthesis of this compound is stimulated by 2E,6E-farnesol, a known precursor for JH III. These data indicate that the P. bioculatus CA- CC product has chemical properties similar to that of other (as of yet unidentified) hemipteran JHs. In addition, we found that the synthesis of this product is sensitive to pH and buffer type; minimally or not affected by the absence of the CC; expressed at similar levels in days 5-30 postemergent adults; and inhibited or decreased in adults reared under low temperature-short day conditions.

Thus, hybrids with low fumonisin accumulation in grain will be valuable for the production of corn-based human food products. We evaluated 68 food-grade dent corn hybrids for severity of Fusarium ear rot and fumonisin accumulation in grain in inoculated trials in Urbana, IL in 2000 and 2001. Our inoculation technique was successful in initiating fumonisin accumulation that allowed discrimination among hybrids. We identified several hybrids that could have acceptable levels (<4 mu g/g) of fumonisin accumulation in Illinois in most years. Twenty-six hybrids with low or high fumonisin accumulation in 2000 were reevaluated in noninoculated trials at three locations in Illinois in 2001. Fumonisin concentration in grain at all three locations was relatively low; thus, separation of hybrids was poor. At two locations, those hybrids with the highest fumonisin concentration in grain also had high concentrations following inoculation. However, one hybrid that had relatively low fumonisin concentration following inoculation had unacceptable levels of fumonisin (5 mu g/g) in natural conditions. Therefore, hybrids need to be evaluated by inoculation and further evaluated at locations where the environment favors fumonisin accumulation.

The stem rust fungus, Puccinia graminis, is functionally an obligate biotroph. Although the fungus can be cultured with difficulty on artificial media, cultures grow slowly and upon subculturing they develop abnormal ploidy levels and lose their ability to infect host plants [) Can. J. Bot. 60, 1827-1836]. P. graminis is a typical heteroecious rust fungus with the full complement of five distinct spore stages that occur during asexual reproduction on its gramineous hosts and sexual reproduction that begins in the resting spore stage and culminates on the alternate host, barberry (Berberis spp.). There appears to be little polymorphism for resistance/susceptibility in Berberis species, but complex polymorphisms of resistance/susceptibility and matching virulence /avirulence exist in gene-for-gene relationships between small grain species and the forms of P. graminis that infect them. Taxonomy:Puccinia graminis is a rust fungus in the phylum Basidiomycota, class Urediniomycetes, order Uredinales, and family Pucciniaceae, which contains 17 genera and approximately 4121 species, of which the majority are in the genus Puccinia[) Ainsworth and Bisby's Dictionary of the Fungi. Wallingford, UK: CAB International]. Various subdivisions of P. graminis into subspecies, varieties and formae speciales have been proposed based on spore size and host range. Crossing studies and DNA sequence comparisons support the separation of at least two subspecies, but not the proposed separation based on spore size. Host range:The host range of P. graminis is very broad compared with that of most Puccinia spp.; it includes at least 365 species of cereals and grasses in 54 genera [) The Cereal Rusts. Orlando, FL: Academic Press, pp. 115-130]. Wheat stem rust, P. graminis f. sp. tritici, was shown to infect 74 species in 34 genera in artificial inoculations of seedlings, but only 28 of those species belonging to eight genera were known to be natural hosts of the fungus. Other formae speciales of P. graminis have narrower host ranges than P. graminis f. sp. tritici. Disease symptoms:Infections in cereals or grasses occur mainly on stems and leaf sheaths, but occasionally they may be found on leaf blades and glumes as well. The first macroscopic symptom is usually a small chlorotic fleck, which appears a few days after infection. About 8-10 days after infection, a pustule several millimetres long and a few millimetres wide is formed by rupture of the host epidermis from pressure of a mass of brick-red urediniospores produced in the infection. These uredinial pustules are generally linear or diamond shaped and may enlarge up to 10 mm long. The powdery masses of urediniospores appear similar to rust spots on a weathered iron surface. With age, the infection ceases production of brick-red urediniospores and produces a layer of black teliospores in their place, causing the stems of heavily infected plants to appear blackened late in the season.

A new strain of BMV, named F-BMV, was identified in a tall fescue (Festuca arundinacea Schreb.) plant. Here, we report the identification and characterization of tall fescue plants resistant to F-BMV, and the effects of F-BMV infection on their growth and development. Susceptible plants infected with F-BMV produced 40% fewer tillers and 42% less dry matter compared with virus-resistant plants in a greenhouse study. In the field, susceptible plants infected with F-BMV produced 25% fewer tillers, 36% less dry matter, 10% less plant height, and 40% lower seed yield compared with virus-resistant plants. In a field evaluation of a tall fescue mapping population, the virus symptom scores were negatively correlated with production of dry matter (r = -0.55), plant height (r = -0.55), and seed yield (r = -0.33). Thus, F-BMV has the potential to cause significant economic damage to susceptible tall fescue plants. These results indicate that the virus can present a serious challenge for long-term maintenance of valuable plant materials. A survey of tall fescue plants from Arkansas, Oklahoma, and Oregon indicated that the prevalence F-BMV in the field was very low.

Single preventive foliar sprays with phosphonate were tested by wounding and inoculating tree trunks and branches with either pathogen at time intervals from 15 days to 5 months after spraying. One to 3 months after inoculation, resulting cankers were measured. Preventive foliar sprays with phosphonate in the fall or spring suppressed development of cankers for up to 5 months after treatment; mean canker lengths on the trees sprayed with phosphonate before inoculation were 22 to 98% smaller than those on trees that received no phosphonate. In subsequent tests, preventive chemigation with phosphonate in spring or summer also inhibited canker expansion. A curative topical treatment with either fosetyl-Al or mefenoxam on cankers caused by P. cactorum or P. citricola reduced canker expansion by 36 to 88%.

It has been studied most extensively for its aromatic compound content. In Florida, rau ram commonly is grown hydroponically in greenhouses using large, cement beds with recirculated water. The plants form dense mats from which new growth is trimmed for market. During January of 2002, a severe dieback was observed in one production house in Saint Lucie County, FL. Plants with less severe symptoms were yellowed and stunted. Roots of symptomatic plants were largely decayed with root symptoms beginning as a tip necrosis. The cortex of severely affected roots slipped off easily, leaving a stringy vascular system. Plating of symptomatic tissue from 20 randomly selected plant samples was performed with multiple general and selective media including potato dextrose agar, corn meal agar with pimaricin, ampicillin, rifampicin, and pentachloronitrobenzene (PARP). All colonies produced were identified as Pythium helicoides Drechsler on the basis of sporangial, oogonial, and antheridial characteristics. Isolates had proliferous, obovoid, papillate sporangia, and were homothallic with smooth-walled oogonia and thick-walled, aplerotic oospores. Multiple antheridial attachments per oogonium were common with the antheridium attached along its entire length. Pathogenicity tests were conducted using P. odoratum plants grown from commercial transplants. Two tests were performed. Each test was conducted using eight inoculated and eight control plants. In the first test, plants were maintained in 10-cm pots immersed in sterilized pond water for the duration of the test. Plants were inoculated with five 7- x 70-mm sections of freshly growing mycelial culture per plant using 10-day-old cultures of Pythium helicoides grown on water agar. Chlorosis was observed at approximately 2 months after inoculation. Root necrosis was observed in inoculated plants approximately 5 months after inoculation. This test was performed in the greenhouse with temperatures ranging from 20 to 30 degree C. The second test was performed in growth chambers at 35 to 40 degree C. Plants were maintained in 10-cm pots immersed in Hoagland's solution and were inoculated with four 6-mm plugs per plant. Symptoms were observed on inoculated plants at this temperature within 1 week of inoculation. No chlorosis or root decay was observed in noninoculated, immersed plants. The pathogen was reisolated from inoculated, symptomatic tissue. To our knowledge, this is the first report of root rot of P. odoratum caused by Pythium helicoides.

Sugar beet lines exhibiting different degrees of susceptibility to the virus yellows complex were inoculated with either one, two, or all three viruses. Severe stunting, as measured by fresh plant biomass, was observed with mixed infections with Beet yellows virus (BYV) and Beet mosaic virus (BtMV), compared to single infections of these viruses. In addition, the overall rate of appearance of Beet western yellows virus (BWYV) symptoms increased during co-infection with BtMV. Synergistic effects on stunting severity, as measured by plant biomass, were more pronounced in susceptible beet lines, but similar patterns also were observed in lines exhibiting tolerance to virus yellows. Relative concentrations of viruses were compared among single and mixed infections using dot-blot hybridization with virus specific probes, and quantified by phosphorimage analysis. Titers of all three viruses increased as a result of co-infection compared with single infections.

The incidence of gray mold among grape berries that were untreated, or immersed for 1 min in ethanol (35% vol/vol) at 25 or 50 degree C, was 78.7, 26.2, and 3.4 berries/kg, respectively, after 1 month of storage at 0.5 degree C and 2 days at 25 degree C. Heated ethanol was effective up to 24 h after inoculation, but less effective when berry pedicels were removed before inoculation. Rachis appearance, epicuticular wax content and appearance, and berry shatter were unchanged by heated ethanol treatments, whereas berry color changed slightly and treated grape berries were more susceptible to subsequent infection. Ethanol and acetaldehyde contents of grape berries were determined 1, 7, and 14 days after storage at 0.5 degree C following treatment for 30 or 90 s at 30, 40, or 50 degree C with water, or 35% ethanol. Highest residues (377 mu g/g of ethanol and 13.3 mu g/g of acetaldehyde) were in berries immersed for 90 s at 50 degree C in ethanol. Among ethanol-treated grape berries, the ethanol content declined during storage, whereas acetaldehyde content was unchanged or increased. Untreated grape berries initially contained ethanol at 62 mu g/g, which then declined. Acetaldehyde content was 0.6 mu g/g initially and changed little during storage.

The algorithm utilizes Cap3 to perform an initial clustering of related EST sequences to produce a consensus sequence of a gene family. These consensus sequences are then used to collect all ESTs in the original EST library that are related using BLAST. A redundancy based criterion is applied to each EST to identify reliable unique gene-sequences. Using a highly inbred genome as a source of ESTs eliminates the necessity of computing covariance on each polymorphism to identify alleles of the same gene, thus making this algorithm more streamlined than other alternatives which must computationally attempt to distinguish genes from alleles.

Thirty-six compost samples from Pacific Northwest commercial composting facilities were analyzed for a number of physical, chemical, and biological properties, including suppression of damping-off caused by Pythium ultimum, P. irregulare, and R. solani. The samples were produced from diverse feedstocks and composting technologies; this was reflected in a large degree of variability in the measured properties. When mixed with sphagnum peat moss and inorganic aggregates, 67% of the compost samples significantly suppressed P. irregulare damping-off of cucumber, 64% suppressed P. ultimum damping-off of cucumber, and 17% suppressed damping-off of cabbage caused by R. solani. Suppression of Pythium damping-off was related to the potential of compost to support microbial activity and a qualitative index of ammonia volatilization. Suppression of Rhizoctonia damping-off was not related to any one compost factor. Currently available compost products potentially could provide commercially acceptable control of damping-off caused by Pythium spp., but it is necessary to fortify composts with microbial antagonists for the control of R. solani.

A main effects log-linear Poisson regression model was constructed to evaluate the association between fiscal year and the rate of E. coli O157: H7-positive raw ground beef samples while controlling for the effect of season for the subset of test results obtained from fiscal year (FY)2000 through FY2003. Rate ratios were used to compare the rate of E. coli O157:H7-positive raw ground beef samples between sequential years to identify year-to-year differences. Of the 26,521 raw ground beef samples tested from FY2000 through FY2003, 189 (0.71%) tested positive for E. coli O157:H7. Year-to-year comparisons identified a 50% reduction in the rate of positive ground beef samples from FY2002 to FY2003 when controlling for season (95% CI, 10 to 72% decrease; P = 0.02). This decrease was the only significant year-to-year change in the rate of E. coli O157:H7-positive raw ground beef samples but was consistent in samples obtained from both federally inspected establishments and retail outlets. We believe this decrease is attributed to specific regulatory actions by Food Safety and Inspection Service and subsequent actions implemented by the industry, with the goal of reducing E. coli O157:H7 adulteration of raw ground beef. Continued monitoring is necessary to confirm that the decrease in the rate of E. coli O157:H7 in raw ground beef samples we observed here represents the beginning of a sustained trend.

Azoles were variably effective against mold fungi that are frequently found on wood and wood products. Unseasoned southern yellow pine specimens that were dip-treated with varying concentrations of eight azoles were evaluated for their ability to resist mold infestation when challenged with Aspergillus niger, Penicillium chrysogenum, and Trichoderma viride spores. Minimal fungicidal concentrations (MFC sub(90)) were determined to be 0.016% for thiabendazole and 0.043% for voriconazole, the most efficacious azoles against the challenge fungi. We conclude that thiabendazole or voriconazole may be used alone or in combination to inhibit mold fungi on unseasoned pine.

Using suspension cells of Nicotiana tabacum we identified four acetophenones and four hydroxycinnamic acid amides that accumulate in this extracellular environment. Treatment of the suspension cells with isolates of the plant pathogen Pseudomonas syringae or heat-killed bacteria increased elicitation of extracellular phenolics and changed the composition of the compounds that accumulated. These phenolics were sensitive to oxidative stress; when suspension cells were treated with bacterial strains or elicitors that triggered an oxidative burst, these phenolics were oxidized and depleted for the duration of the burst. The qualitative and quantitative makeup of phenolics produced by N. tabacum suspensions was also affected by plant cell age and density. To our knowledge, this is the first study that closely follows the kinetics of individual extracellular phenolic compounds and the concurrent oxidative stress during the first few hours of a plant-bacterial interaction.

The 14,615bp plasmid, designated pSKU146, has a nucleotide content of 28mol% G+C, and contains 18 potential protein-coding regions (open reading frames, ORFs), of which six encode proteins that exhibit similarity to virulence-associated proteins involved in cell-to-cell adhesion or conjugal DNA transfer. One ORF encodes a 96kDa protein, SkARP1, that is highly similar to SARP1 adhesin involved in attachment of Spiroplasma citri to insect vector gut membrane. Five ORFs encode proteins similar to TraE and Mob in walled bacteria, and to ORFs found in the integrative, conjugative element (ICEF) of Mycoplasma fermentans, respectively. Presence of domains similar to proteins of the Type IV secretion system in pathogenic bacteria suggests that spiroplasma possesses a related translocation system. Plasmid pSKU146 also contains two identical oriT regions each containing a nick sequence characteristic of the IncP conjugative plasmid family, as well as a 58bp palindromic sequence, palSK1. Features in pSKU146 suggest that the plasmid functions as a mobile genetic element in conjugative transmission of spiroplasma pathogenicity-related genes.

Soil aggregate size distributions are commonly used to characterize soil structure. Relationships between density of dry soil aggregates and aggregate size present a different way to use aggregate-related information in soil structure characterization. Those relationships have been simulated assuming soils to be mass fractals. Aggregates in field soil are not air-dry. The relationships between mass and size differ between dry aggregates and wet aggregates because aggregates shrink as water content decreases. Our objective was to find out whether the mass fractal model can be applied to wet aggregates. Aggregates from the plow layer of Greyzem soil were brought to four different levels of water contents, and the kerosene method was used to measure volume of aggregates within diameter ranges of 3-5, 5-7, and 7-10 mm. It appeared that the wetter aggregates were less prone to loosening as the water increased. The mass fractal model was applicable to wet aggregates under the assumption of linear dependence of the fractal dimension D sub(m) and the unit size aggregate mass a on the gravimetric water content w (g g super(-1)). Dependencies D sub(m)=2.925+0.284w and a=0.808-0.123w resulted in R super(2)=0.9999 for the regression line of simulated versus measured aggregate mass. Fractal modeling of mass-size scaling in wet soil aggregates presents a set of aggregate-based parameters for soil structure that may reflect soil properties and can be explored as an index of soil ability to support functions of ecosystems.

Yellow sticky traps were used to qualify and quantify the number of aerial leafhoppers from 1 May 2001 until 4 September 2001. A total of 45 species from eight different leafhopper subfamilies, for a total of 6055 individuals, were considered in this study. The mean number of leafhoppers collected, mean species richness, diversity and evenness were significantly lower on traps of trees for 'October Glory' than for the other clones. Yet, none of the leafhopper species dominated the weekly samples. Species similarity among clones ranged from 56 to 90%. No two clones had complete similarity. 'Franksred' and trees of a controlled cross between 'October Glory' x 'Autumn Flame' shared the highest degree of species similarity, while clones from PA, USA and RI, USA were the least similar. The development of new clones did not create new pest problems, but suppressed populations of damaging pests, and maintained the diversity of low abundance species.

Inoculated whole kernels were compared to noninoculated kernels. Concentrations of sucrose and raffinose in inoculated seed decreased to nearly zero at 6 days, whereas concentrations of these saccharides in noninoculated seed dropped at a considerably slower rate, and significant levels remained at the end of the incubation period. Triglyceride concentrations remained unchanged in the noninoculated seed but dropped continuously after 2 days in the inoculated seed. Starch and zein concentrations did not change during the 12-day incubation period. Aflatoxin B sub(1) was first detected after 2 days and increased to about 20 mu g/g (20,000 ppb) after 12 days. Very low aflatoxin concentrations were detected in the noninoculated seed. Significant concentrations of erythritol, arabitol, and mannitol were produced during infection, with peak concentrations occurring at 8 days. Whole seed and germ tissue appeared to support good fungal growth and aflatoxin production, whereas ground tissues and endosperm did not. A. flavus preferentially utilized saccharides as initial carbon substrates followed by triglycerides. When invading nonwounded corn kernels, the fungus selectively targets the germ tissue where these materials are localized in the highest concentrations.

Stukenia pectinatus, Potamogeton nodosus, and Hydrilla verticillata (monoecious type) were grown in either monocultures or mixtures in Polyvinylchloride containers. Four 5 cm diameter minirhizotrons were mounted horizontally across the containers so that they were 2.5, 12.5, 22.5, or 32.5 cm below the surface of the sediment, and we inserted a specialized video camera in each minirhizotron tube and recorded root images at 21 locations in each tube. For two of three cases, adding plants of another species changed the root depth distribution and increased the volume of soil occupied by roots compared to monocultures. Additionally, smaller diameter roots were more abundant when competitors were present. This implies that the plants adjusted to the presence of competitors by producing more roots capable of nutrient uptake. These results imply that competition for sediment-based nutrients occurred in these systems.

We tested hydroquinone as a phagostimulant using workers from three colonies of the Formosan subterranean termite, Coptotermes formosanus, under both laboratory and field conditions. Hydroquinone at concentrations ranging from ca. 0.002-20.0 ng/cm super(2) did not increase visitation by C. formosanus workers to treated over control filter papers, and was actually repellent at a 20 ng/cm super(2) dose. No phagostimulant response to hydroquinone was observed in two colonies. In the third, there was a significant increase in feeding on filter paper treated with a 2 ng/cm super(2) dose, but was significantly lower at a 20 ng/cm super(2) dose. Furthermore, sand treated with a gradient of hydroquinone, did not evoke increased tunneling activity compared with controls. GC-MS analysis of C. formosanus workers indicated that hydroquinone was present at an average of 41 pg/worker. It was also determined that within one week about 11%hydroquinone in aqueous solution oxidized to 1,4-benzoquinone. Our findings indicate that hydroquinone alone does not act as a phagostimulant but instead may act as a repellent at higher concentrations.

Fusions of the F, HN and HN2 (duplicated HN epitope) were made in the internal bH-bI loop (motif 5) within the CMV CP. Recombinant RNA3 transcripts of the Ixora strain of CMV were inoculated on to Nicotiana benthamiana, together with CMV RNA1 and CMV RNA2. When the F and HN epitopes were placed in the internal motif, the modified virus was infectious and the HN NDV epitope was recognized by anti-NDV sera. However, in some plants, deletions of one to several of the inserted amino acids occurred. A duplication of the HN epitope rendered the virus non-viable.

'Greenness' has been proposed as an indicator of herbage quality in semiarid environments, particularly nitrogen (N) content. The objective of this study was to assess the potential of estimating N content of forage using dead:green ratios and accumulated growing-degree-days (AGDD). Standing crop samples were collected April through October over 3 years from each of 3 replicated grazing regimes on a silty range site in eastern Montana. Samples were sorted into live, current dead, and old dead components, then dried, ground, and analyzed for N content. The AGDD for base temperature 45 degree F (7.2 degree C) was calculated from National Oceanic and Atmospheric Administration (NOAA) reported monthly average temperatures for Miles City. An equation to predict percent N in the total standing crop from percent dead forage and AGDD was developed using multiple linear regression. This equation accounted for 75.9% of variation in percent N, and prediction error variance was 0.026. To validate this equation, data were obtained from samples collected from April through September in an independent study of 8 areas on silty and clay-pan range sites grazed during autumn and winter. Samples from these sites were treated and analyzed in the same manner as those used to develop the equation. The developed equation was used to predict percent N for the validation data. The resulting correlation between predicted and actual values was 0.79. The regression coefficient for actual values on predicted values was 0.995 plus or minus 0.125. The intercept did not differ from 0.0 (P = 0.22), and prediction error variance was 0.042. This equation has utility for predicting N level of forage from Northern Great Plains rangelands.Original Abstract: La cantidad y calidad del forraje son factores importantes que afectan la produccion animal en los pastizales. 'Verdor' ha sido propuesto como un indicador de la calidad del forraje, particularmente del contenido de nitrogeno (N), en los ambientes semiaridos. El objetivo de este estudio fue evaluar el potencial para estimar el contenido de N del forraje usando relaciones de forraje muerto:forraje verde y los dias-grado-crecimiento acumulados (AGDD). Se colectaron muestras de biomasa en pie de Abril a Octubre durante un periodo de 3 anos en 3 regimenes de apacentamiento repetidos 3 veces cada uno, ubicados en un sitio de pastizal aluvial del este de Montana. Las muestras se clasificaron en los siguientes componentes: biomasa viva, biomasa recien muerta y biomasa muerta vieja; posteriormente se molieron y analizaron para determinar el contenido de N. Los dias-grado-crecimiento acumulados, tomando como base 45 degree F (7.2 degree C), se calcularon a partir de las temperaturas promedio mensuales de Mile City reportadas por la Administracion Nacional Atmosferica y Oceanica (NOAA). Mediante tecnicas de regresion multiple se desarrollo una ecuacion para predecir el contenido de N en la biomasa en pie total a partir del porcentaje de forraje muerto y los AGDD. La ecuacion explico el 75.9% de la variacion del contenido de N y la varianza del error de prediccion fue 0.026. Para validar esta ecuacion, se obtuvieron datos de muestras colectadas de Abril a Septiembre en un estudio independiente de 8 areas en sitios de pastizal de aluviales y arcillosos apacentados durante el otono e invierno, las muestras de estos sitios fueron tratadas y analizadas de la misma manera que las utilizadas para desarrollar la ecuacion. La ecuacion desarrollada fue usada para predecir el porcentaje de N para la validacion de los datos. La correlacion resultante entre los valores predichos y los valores actuales fue de 0.79. El coeficiente de regresion para los datos actuales sobre los datos predichos fue 0.995 plus or minus 0.125. La intercepcion no difirio de 0.0 (P = 0.22) y la varianza del error de prediccion fue 0.042. Esta ecuacion tiene utilidad para predecir el nivel de N del forraje de los pastizales de las Grandes Planicies del Norte.

Pers.] in manure nutrient management is limited to summer haying. This study was done to determine how hay yield and nutrient uptake in a manure-fertilized Tifton 44 field were affected by fall overseeding and spring haying with berseem clover (Trifolium alexandrinum L.), crimson clover (T. incarnatum L.), annual ryegrass (Lolium multiflorum L.), and wheat (Triticum aestivum L.). Overseeding treatments were compared with a nonoverseeded control on Mantachie loam (fine, siliceous, acid, thermic Aeric Fluvaquents) receiving 168 kg P ha super(-1) in swine (Sus scrofa domesticus) effluent. Spring hay was cut April-June and summer hay July-October 2000-2002. Dry matter (DM) (4.4-5.5 Mg ha super(-1) yr super(-1)) and P uptake (12.2-17.1 kg ha super(-1) yr super(-1)) of spring berseem clover hay were higher than the control in 2 of 3 yr and higher than other treatments in 2002. Total DM and P uptake with berseem clover overseeding were 10% higher than the control. Final Mehlich-3 P soil levels (0-5 cm) tended to be lower in the berseem clover treatment than the control (65 vs. 81 mg kg super(-1), respectively). Spring berseem clover hay was higher in N (94-122 kg ha super(-1) yr super(-1)) than the control each year and higher than other treatments in 2 of 3 yr. Summer Tifton 44 hay in the berseem clover treatment had more DM in 2002 and higher N uptake in 2001 and 2002 than other treatments. No treatment reduced Tifton 44 yield or nutrient uptake. Overseeding increased hay yield and nutrient uptake, and berseem clover was as good as or better than other treatments.

Pers.] is commonly used to manage field-applied manure P in the southeastern USA but is limited to summer. This 3-yr study was done to examine effects of extending the haying season by spring haying of fall-overseeded annuals. Berseem clover (Trifolium alexandrinum L.), crimson clover (T. incarnatum L.), annual ryegrass (Lolium multiflorum L.), and wheat (Triticum aestivum L.) were compared with a nonoverseeded control. Dry matter (DM) yield and N and P uptake were measured in spring and summer hay on a Prentiss sandy loam (coarse-loamy, siliceous, thermic Glossic Fragiudults, Ultisols) with high soil P following 6 yr of swine (Sus scrofa domesticus) effluent fertilization. Fall-seeded plots were cut twice for spring hay and three times for summer hay. Spring hay of annual ryegrass (3.8-5.3 Mg ha super(-1) yr super(-1)) yielded more DM than crimson clover (2.6-3.4 Mg ha super(-1) yr super(-1)), wheat (2.5-3.3 Mg ha super(-1) yr super(-1)), and the control (2.8-3.4 Mg ha super(-1) yr super(-1)) every year but did not differ from berseem clover (3.1-4.6 Mg ha super(-1) yr super(-1)) in 2 of 3 yr. Phosphorus uptake in spring hay of annual ryegrass and berseem clover (10-16 kg ha super(-1)) was higher than crimson clover (8-12 kg ha super(-1)), wheat (7-12 kg ha super(-1)), and the control (6-11 kg ha super(-1)). Nitrogen uptake in spring hay was higher in berseem clover (71-128 kg ha super(-1)) than other treatments (43-80 kg ha super(-1)), which did not differ. No differences occurred in summer hay (DM = 3.9-7.6 Mg ha super(-1), N = 72-191 kg ha super(-1), P = 13-21 kg ha super(-1)). Overseeding common bermudagrass with berseem clover or annual ryegrass can improve hay yield and P removal.

At each site, a randomized complete block design with a factorial arrangement of treatments replicated four times was used. Treatments were multiple effluent irrigations resulting in four N rates from 0 to 665 kg N ha super(-1) yr super(-1). In each block, commercial fertilizer (N, P, and K) treatments were applied to additional plots at rates equivalent to swine effluent rates. Total dry matter yield and crude protein (CP) for bermudagrass and johnsongrass reached a plateau with application of approximately 450 kg N ha super(-1) from either swine effluent or commercial fertilizer. Neutral detergent fiber (NDF) and acid detergent fiber (ADF) peaked at the low fertilization rate and then declined with increasing effluent and commercial fertilizer rates. An inverse relationship was obtained for in vitro true digestibility (IVTD) in response to fertilization rate for both grasses. Forage dry matter, CP, NDF, and ADF levels peaked in the July harvest and then declined, but forage IVTD level declined in July harvest. Only in July 1996, forage NO sub(3)-N concentration was lower for swine effluent than commercial fertilizer. Swine effluent and commercial fertilizer had similar effects on forage dry matter yield and nutritive value.

The purpose of this paper is to review research on water use efficiency and precipitation use efficiency (PUE) as affected by cropping system and management in the Great Plains. Water use efficiency and PUE increase with residue management practices that increase precipitation storage efficiency, soil surface alterations that reduce runoff, cropping sequences that minimize fallow periods, and use of appropriate management practices for the selected crop. Precipitation use efficiency on a mass-produced basis is highest for systems producing forage (14.5 kg ha super(-1) mm super(-1)) and lowest for rotations with a high frequency of oilseed crops (4.2 kg ha super(-1) mm super(-1)) or continuous small-grain production in the southern plains (2.8 kg ha super(-1) mm super(-1)). Precipitation use efficiency when calculated on a price-received basis ranges from $1.20 ha super(-1) mm super(-1) (for an opportunity-cropped system with 4 of 5 yr in forage production in the southern plains) to $0.30 ha super(-1) mm super(-1) for a wheat (Triticum aestivum L.)-grain sorghum [Sorghum bicolor (L.) Moench]-fallow system in the southern plains}. Throughout the Great Plains region, PUE decreases with more southern latitudes for rotations of similar makeup of cereals, pulses, oilseeds, and forages. Forage systems in the southern Great Plains appear to be highly efficient when PUE is computed on a price-received basis.

Stably transformed calli were recovered as early as 7 weeks after bombardment and GUS-positive shoots regenerated 3 months after bombardment. The efficiency of transformation ranged from 0.9% to 3.7%, and stable integration of the uidA gene into the genome was confirmed by Southern blot analysis. The main advantages of direct bombardment of leaves to regenerate transformed sugar beet include (1) a readily available source of highly regenerative target tissue, (2) minimal tissue culture manipulation before and after bombardment, and (3) the overall rapid regeneration of transgenic shoots.

Experimental and modeling studies were undertaken to examine the roles of attachment, detachment, and straining on oocyst transport and retention. Saturated column studies were conducted using Ottawa aquifer sands (U.S. Silica, Ottawa, IL) with median grain sizes of 710, 360, and 150 mu m. Decreasing the median sand size tended to produce lower effluent concentrations, greater oocyst retention in the sand near the column inlet, and breakthrough of oocysts at later times. Oocyst transport data also exhibited concentration tailing. Mathematical modeling of the oocyst transport data using fitted first- order attachment and detachment coefficients provided a satisfactory description of the observed effluent concentration curves, but a poor characterization of the oocyst spatial distribution. Modeling of these data using an irreversible straining term that is depth dependent provided a better description of the oocyst spatial distribution, but could not account for the observed effluent concentration tailing or late breakthrough times. A more physically realistic description of the data was obtained by modeling attachment, detachment, and straining. The percentage of total oocysts retained by straining was estimated from effluent mass balance considerations to be 68% for 710- mu m sand, 79% for 360- mu m sand, and 87% for 150- mu m sand. Straining coefficients were then selected to achieve these percentages of total oocyst retention, and attachment and detachment coefficients were fitted to the effluent concentration curves. Dramatic differences in the predicted oocyst breakthrough curves were observed at greater transport distances for the various model formulations (inclusion or exclusion of straining). Justification for oocyst straining was provided by trends in the transport data, simulation results, pore size distribution information, and published literature.

This study quantified sediment P flux in Lake Eucha, northeastern Oklahoma, USA, and evaluated the effectiveness of chemical treatment to reduce sediment P flux. Six intact sediment-water columns were collected from three sites in Lake Eucha near the reservoir channel at depths of 10 to 15 m. Three intact sediment and water columns from each site were incubated for 21 d at approximately 22 not equal to under aerobic conditions, and three were incubated under anaerobic conditions (N sub(2) with 300 ppm CO sub(2)); sediment P flux was estimated over the 21 d for each core. The overlying water in the cores was bubbled with air for approximately 1 wk and then treated with aluminum sulfate (alum). The cores were incubated at approximately 22 not equal to for an additional 14 d under aerobic or anaerobic conditions, and sediment P flux after alum treatment was estimated for each core. Sediment P flux was approximately four times greater under anaerobic conditions compared with aerobic conditions. Alum treatment of the intact sediment-water columns reduced (8x) sediment P flux under anaerobic conditions. Internal P flux (1.03 and 4.40 mg m super(-2) d super(-1) under aerobic and anaerobic conditions, respectively) was greater than external P flux (0.13 mg m super(-2) d super(-1)). The internal P load (12 Mg yr super(-1)) from reservoir bottom sediments was almost 25% of the external P load (approximately 48 Mg yr super(-1)) estimated using a calibrated watershed model.

Computer modeling can help identify agricultural areas with high potential P transport. Most models use a constant extraction coefficient (i.e., the slope of the linear regression between filterable reactive phosphorus [FRP] in runoff and soil P) to predict dissolved P release from soil to runoff, yet it is unclear how variations in soil properties, management practices, or hydrology affect extraction coefficients. We investigated published data from 17 studies that determined extraction coefficients using Mehlich-3 or Bray-1 soil P (mg kg super(-1)), water-extractable soil P (mg kg super(-1)), or soil P sorption saturation (%) as determined by ammonium oxalate extraction. Studies represented 31 soils with a variety of management conditions. Extraction coefficients from Mehlich-3 or Bray-1 soil P were not significantly different for 26 of 31 soils, with values ranging from 1.2 to 3.0. Extraction coefficients from water- extractable soil P were not significantly different for 17 of 20 soils, with values ranging from 6.0 to 18.3. The relationship between soil P sorption saturation and runoff FRP ( mu g L super(-1)) was the same for all 10 soils investigated, exhibiting a split-line relationship where runoff FRP rapidly increased at P sorption saturation values greater than 12.5%. Overall, a single extraction coefficient (2.0 for Mehlich-3 P data, 11.2 for water-extractable P data, and a split-line relationship for P sorption saturation data) could be used in water quality models to approximate dissolved P release from soil to runoff for the majority of soil, hydrologic, or management conditions. A test for soil P sorption saturation may provide the most universal approximation, but only for noncalcareous soils.

Staphylococcal enterotoxin B (SEB) is highly heat resistant and is a potential bioterrorism agent. Our research objective was to develop a competitive immunoassay using a surface plasmon resonance (SPR) biosensor for the detection of SEB below 1 ng/mL [part per billion (ppb)] in fresh fluid milk. The assay consisted of SEB immobilization on the sensor surface. An anti-SEB was allowed to bind with the SEB in samples off line prior to the biosensor analysis. The excess and unbound anti-SEB was then captured by SEB sensor. The assay conditions were optimized to detect SEB in HEPES buffer and in whole milk. An analysis of milk samples spiked with 0.312-50 ppb. SEB consisted of heating the samples at 95C followed by rapid cooling and centrifugation at 2961 X g to separate the skim fraction. Aliquots of the skim fraction containing SEB were allowed to bind with anti-SEB for 30 or 60 min. The SEB and anti-SEB complex were separated from the free anti-SEB by centrifugation, and the supematants were injected over the sensor. SEB was detectable in buffer at 0.78-50 ppb and in spiked whole and skim milk from 0.312-25 ppb. The biosensor analysis including the sensor regeneration was 15 min per sample in a fully automated system. The competitive assay format resulted in higher detection sensitivity and greater sample throughput than the SPR biosensor sandwich assay. The competitive assay will be utilized for the detection of SEB in various foods and will be optimized for the detection of other staphylococcal toxins in foods.

We explore spatial and temporal patterns of breeding and recruitment by eastern spadefoot toads (Scaphiopus holbrookii), using nine years of data from continuous monitoring with drift fences and pitfall traps at eight ephemeral ponds in longleaf pine-wiregrass sandhills. Breeding events ( greater than or equal to 25 adults at a pond within a month) occurred 23 times on nine occasions at seven of the eight study ponds, but substantial recruitment ( greater than or equal to 100 metamorphs) followed only five events. Recruitment ranged from 0-4648 among ponds. Only four ponds functioned as population 'sources', and only during some years. The other ponds, and even 'source' ponds during some years, functioned either as 'sinks,' where breeding occurred with no resulting recruitment, or were not used at all for breeding. Most recruitment occurred during four years. Recruitment was correlated with adult breeding effort, but only during some years. Recaptures were rare, and inter-pond exchange of adults was minimal and short-distance (<130 m; one was 416 m). Most (83.5%) individuals captured were metamorphs, and 15.9% were greater than or equal to 51 mm (est. greater than or equal to 4 yr). We conservatively estimated a 7-yr lifespan. Adult 'population' trends clearly reflected breeding effort rather than numbers per se; capture rates fluctuated dramatically among years, but showed no overall trends during the 9-yr study. Our paper is provides empirical information that can be used to generate realistic metapopulation models for S. holbrookii as a tool in conservation planning.

AN - 17120524; 6179954 AB - Day-old broiler chicks (n = 30) were obtained from a commercial hatchery and inoculated, either orally or intracloacally, with a characterized strain of Campylobacter jejuni. At 1 hr, 1 day, and 1 wk after inoculation, broilers (n = 5) from the orally and intracloacally inoculated groups along with control birds (n = 4) were humanely killed by cervical dislocation. The broilers from the control and treatment groups were aseptically opened, and the thymus, spleen, liver/gallbladder, bursa of Fabricius, and ceca were aseptically removed and individually analyzed for C. jejuni. Overall, C. jejuni was isolated after oral inoculation from 13% (10/75), 17% (13/75), and 28% (14/50) of the 1-hr, 1-day, and 1-wk samples, respectively. Campylobacter jejuni was isolated from 10% (4/40), 8% (3/40), 10% (4/40), 25% (10/40), and 40% (16/40) of the thymus, spleen, liver/gallbladder, bursa of Fabricius, and ceca samples, respectively. Following the intracloacal route of inoculation, C. jejuni was recovered from 32% (24/75), 8% (6/75), and 16% (8/50) of the 1-hr, 1-day, and 1-wk samples, respectively. Campylobacter jejuni was isolated from 5% (2/40), 5% (2/40), 5% (2/40), 45% (18/40), and 40% (16/40) of the thymus, spleen, liver/gallbladder, bursa of Fabricius, and ceca samples, respectively, for all sampling periods. Campylobacter spp. were not recovered from sample sites examined from the control broilers from trial one, trial two, or trial three samples examined after 1 hr and 1 day. However, one control sample was positive from the 1-wk sampling from repetition three; therefore, those data were omitted. The rapid movement of Campylobacter to internal organs following both oral and intracloacal inoculation may be significant, particularly if it persists in these organs as reservoirs throughout the 65-wk life cycle of breeding birds.Original Abstract: Pollos de engorde de un día de edad (n = 30), provenientes de una incubadora comercial fueron inoculados por vía oral o intracloacal con una cepa conocida de Campylobacter jejuni. Luego de la primera hora, primer día y primera semana posteriores a la inoculación se procedió al sacrificio por dislocación cervical de cinco pollos de los grupos inoculados oral e intracloacalmente y de cuatro pollos del grupo control. Los pollos pertenecientes a los tratamientos y al grupo control fueron necropsiados asépticamente. El timo, bazo, hígado/vesícula biliar, bolsa de Fabricio y ciego fueron removidos asépticamente y analizados individualmente para determinar la presencia de Campylobacter jejuni. Después de la inoculación oral, se aisló Campylobacter jejuni del 13% (10/75), 17% (13/75), y 28% (14/50) de las muestras obtenidas a la primera hora, primer día y primera semana, respectivamente. Se aisló Campylobacter jejuni del 10% (4/40), 8% (3/40), 10% (4/40), 25% (10/40), y 40% (16/40) de las muestras de timo, bazo, hígado/vesícula biliar, bolsa de Fabricio y el ciego, respectivamente. Posterior a la inoculación por vía intracloacal, se aisló Campylobacter jejuni del 32% (24/75), 8% (6/75), y 16% (8/50) de las muestras obtenidas a la primera hora, primer día y primera semana, respectivamente. Se aisló Campylobacter jejuni del 5% (2/40), 5% (2/40), 5% (2/40) y 45% (18/40), y 40% (16/40) de las muestras de timo, bazo, hígado/vesícula biliar, bolsa de Fabricio, y el ciego, respectivamente, para cada uno de los periodos de muestreo. No se aislaron especies de Campylobacter en las muestras examinadas después de una hora y un día después de la inoculación en los pollos control durante el primero, segundo o tercer ensayo. Sin embargo, en el muestreo de una semana se encontró una muestra control positiva después de la tercera repetición, por lo que los datos fueron omitidos. El rápido movimiento del Campylobacter hacia órganos internos luego de la inoculación tanto oral como intracloacal puede ser significante, particularmente si este persiste en estos órganos como reservorio durante las 65 semanas del ciclo de vida de la aves reproductoras.

We examined the understory of an old-growth mixed-conifer Sierran forest and its distribution in relation to microsite conditions. The forest has high species richness (98 species sampled), most of which are herbs with sparse cover and relatively equal abundance. Shrub cover is highly concentrated in discrete patches. Using overstory tree cover and microsite environmental conditions, four habitats were identified; tree cluster, partial canopy, gap, and rock/shallow soil. Herb and shrub species were strongly linked with habitats. Soil moisture, litter depth and diffuse light were the most significant environmental gradients influencing understory plant distribution. Herb cover was most strongly influenced by soil moisture. Shrub cover is associated with more diffuse light, less direct light, and sites with lower soil moisture. Herb richness is most affected by conditions which influence soil moisture. Richness is positively correlated with litter depth, and negatively correlated with direct light and shrub cover. Disturbance or management practices which change forest floor conditions, shallow soil moisture and direct light are likely to have the strongest effect on Sierran understory abundance and richness.

Cross polarization magic angle spinning super(13)C nuclear magnetic resonance revealed that total carbon and nutrient concentrations correlated strongly with carbohydrate and O-alkyl carbon concentrations but did not relate well with concentrations of lignin, aromatic and phenolic carbon, or with lignin-related decomposition indices. The best correlations to carbon and nutrient concentrations occurred with the C/N (R super(2)=0.86, P > 0.0001) and alkyl/O-alkyl (R super(2)=0.75, P > 0.0001) decomposition indices. In all situations, the carbon chemistry of the decomposing litter followed the general pattern of accumulation of alkyl and carbonyl carbon with a loss of O-alkyl and methoxy carbon. Only small variations in the aromatic and phenolic carbon concentrations were detected. Since lignin is composed primarily of aromatic and phenolic carbons, the observation that there were only small changes in the aromatic and phenolic carbons of the litter is consistent with the general stability of lignin in these ecosystems. Trends in carbon chemistry during decomposition suggested that fertilization accelerated the decomposition process by about 100% as compared with the control plots. Irrigation also accelerated the decomposition process but to a lower extent (about 62% greater than control plots). Initial litter quality, as defined by the litter C/N, did not have a significant effect on the carbon chemistry of the decomposing litter. This study demonstrated that the decomposition mechanisms were not altered by the treatments but there were important changes in the relative chemistry of the decomposing litter which impacted the rate of decomposition.

The ISR of 30 F. columnare strains and other Flavobacterium species was amplified using universal primers and sequenced. Once F. columnare specific sequences within the ISR were recognized, specific PCR primers were designed against them (FCISRFL and FCISRR1). The primers were sensitive and able to detect as low as 7 colony forming units from pure culture by PCR. The new PCR detection method was applied to experimentally infected channel catfish. Two different experiments in which channel catfish fingerlings were infected by intramuscular injection or by immersion bath showed the advantage of the PCR method over standard culture techniques. F. columnare was detected by PCR in both tank water and catfish tissue samples with a higher frequency and in less time than standard microbiological methods. Furthermore, PCR detection confirmed that F. columnare can be transmitted horizontally indirectly through the water column without fish-to-fish contact. The newly developed PCR detection method for F. columnare was more sensitive and rapid than standard culture on bacteriological media for detection of F. columnare in channel catfish tissues and in tank water.

AN - 67394791; 15680403 AB - Folate is essential for the synthesis, repair and methylation of DNA. Folate depletion causes nuclear genetic and epigenetic aberrations in cell culture, rodents and humans. We hypothesized that folate depletion may also damage mitochondrial (Mt) DNA and induce large-scale deletions due to DNA breakage. MtDNA deletions and mutations accumulate during aging and tumorogenesis and may play causative roles in these processes. Weanling and adult (12 months) Sprague Dawley rats consumed folate deplete, replete and supplemented diets (0, 2 and 8 mg/kg folate, respectively) for 20 weeks. The presence of random and common (4.8 kb) MtDNA deletions was measured in colonic mucosa and liver. Six Mt genomes (<16 kb) harboring random deletions were detected in the liver (3.5-7.0 kb) and three in the colon (3.8-8 kb). Older rats had significantly more random hepatic MtDNA deletions than young rats (64 and 3.2% of samples, respectively, P<0.0001), while age had no effect on these deletions in the colon (3.1 and 7.7% in young and old, respectively). Folate intake had no effect on the frequency of random deletions in either tissue. There was no discrete effect of aging on the common 4.8 kb deletion in the liver or colon. However, in the liver of old rats, increasing amounts of dietary folate reduced the deletion frequency, with replete and supplemented rats having 2.2- and 3.2-fold less deletions than the depleted rats. Our results confirm that random MtDNA deletions accumulate with age in a tissue-specific fashion. Furthermore, in contrast to previous work, we report that the common 4.8 kb deletion was not modulated by age, but is reduced by folate supplementation in the liver of rats.

A variety of pretreatments, applied to the enzyme prior to introduction to the nonpolar media, can improve enzyme activity. However, the various pretreatments have not been studied using directly comparable conditions, nor have they been applied simultaneously to test for interactive effects. This work evaluates pretreatment of lipase with various classes of additives. The pretreated lipase is used to catalyze esterification between citronellol and acetic acid in a medium of n-hexane. The effectiveness of a particular pretreatment is presented in terms of relative performance (RP), which is equal to the number of times faster the pretreated lipase catalyzes the reaction relative to untreated lipase. The individual and interactive effects of the pretreatment factors were studied and compared. Buffer salts had a much stronger performance-enhancing effect than nonbuffer salts; pretreatment with 90% (w/w) sodium phosphate yielded lipase with an RP of approx 64. A strong interaction was found between the treatments with sodium phosphate and pH adjustment. These treatments may mitigate the inhibitory effect of acetic acid. Activating effects of phase interfaces and active-site protectants are shown to be complementary to other treatments, demonstrating that they likely act by distinct mechanisms.

The ethanol/water medium is necessary to preserve the fibrous form of carboxymethyl gauze/nonwovens with a degree of substitution of 0.3 to 0.4. From the behavior of antimicrobial release and the suppression of bacterial and fungal proliferation, it is apparent that the dressings containing the silver antimicrobial agent will protect wound surfaces from microbial invasion and effectively suppress bacterial proliferation. Antimicrobial evaluations of Ag/Na carboxymethyl cotton at North American Science Associates and the Southern Regional Research Center are positive. Additionally, the results show that an enhanced burn treatment is possible using a highly moisture retentive sodium carboxymethyl gauze instead of conventional gauze now used with silver nitrate. The carboxymethyl gauze's capacity to hold a large amount of antimicrobial solution creates the possibility for better antimicrobial treatment. The retention of a greater amount of silver nitrate solution on the dressing will require less replenishment of solution on dressings on patients, which will reduce nursing time.

AN - 67557952; 15792371 AB - The circadian system is a flexible framework allowing a proper adjustment of physiological functions to the regularly changing environment. Pathways that are used to synchronize components of the circadian system have been shown to be susceptible to pathophysiological conditions. In our study, we investigated effects of streptozotocin (STZ)-induced diabetes mellitus on function of the circadian system at the level of melatonin synthesis and expression of per2 and dbp in the heart and liver in 8-week-old Wistar rats. Rhythmic pattern of clock gene per2 and transcription factor dbp in controls and STZ-treated animals was determined. Streptozotocin administration had a more substantial effect on per2 expression in the liver than in the heart. Pronounced phase advance in the rhythm of dbp expression in both the liver and the heart was observed. The melatonin rhythm reflecting the phase of the master clock was not affected by STZ application. Changes in per2 and dbp expression in the heart and liver imply alterations in input pathway or peripheral oscillators with possible consequences on function of analysed organs.

AN - 67454065; 15726967 AB - The hides of cattle are the source of Escherichia coli O157:H7 that contaminates beef carcasses during commercial beef processing. Therefore, effective interventions that reduce hide contamination should reduce subsequent carcass contamination. The first objective of this study was to identify the most effective reagents for decontamination of beef hides. Cattle hides draped over barrels were used for in vitro experiments to compare the efficacy of washes using 1.6% sodium hydroxide, 4% trisodium phosphate, 4% chlorofoam, or 4% phosphoric acid, each followed by a rinse step using either water or acidified (pH 7.0) chlorine at 200 or 500 ppm. All treatments using a water rinse reduced hide coliform counts by 1.5 to 2.5 log CFU/ 100 cm2. Compared with water rinses, 200 and 500 ppm acidified chlorine rinses increased efficacy by approximately 1.0 and 2.0 log CFU/100 cm2, respectively. Vacuuming of the treated areas to remove excess liquid improved hide cleanliness by an average of an additional 1.0 log CFU/100 cm2. The second objective was to evaluate the use of an on-line hide-wash cabinet that used a sodium hydroxide wash and a chlorinated (1 ppm) water rinse. Hides sampled before entering and after exiting the cabinet had aerobic plate counts and Enterobacteriaceae counts that were reduced by 2.1 and 3.4 log CFU/100 cm2, respectively, and the prevalence of E. coli O157 on hides was reduced from 44 to 17% when the cabinet was in use. Preevisceration carcass aerobic plate counts and Enterobacteriaceae counts were both reduced by 0.8 log CFU/100 cm2, and the prevalence of E. coli O157 on preevisceration carcasses was reduced from 17 to 2% when the cabinet was in use. These results support decontamination of hides as an effective means to reduce pathogen contamination of cattle carcasses during processing.

AN - 67349008; 15581508 AB - alpha-Solanine and alpha-chaconine are two naturally occurring steroidal glycoalkaloids in potatoes (Solanum tuberosum), and solanidine-N-oxide is a corresponding steroidal aglycone. The objective of this research was to screen potential cyto-toxicity of these potato glycoalkaloids using bovine oocyte maturation, in vitro fertilization techniques and subsequent embryonic development as the in vitro model. A randomized complete block design with four in vitro oocyte maturation (IVM) treatments (Experiment 1) and four in vitro embryo culture (IVC) treatments (Experiment 2) was used. In Experiment 1, bovine oocytes (n=2506) were matured in vitro in medium supplemented with 6 microM of alpha-solanine, alpha-chaconine, solanidine-N-oxide or IVM medium only. The in vitro matured oocytes were then subject to routine IVF and IVC procedures. Results indicated that exposure of bovine oocytes to the steroidal glycoalkaloids during in vitro maturation inhibited subsequent pre-implantation embryo development. Potency of the embryo-toxicity varied between these steroidal glycoalkaloids. In Experiment 2, IVM/IVF derived bovine embryos (n=2370) were cultured in vitro in medium supplemented with 6 microM of alpha-solanine, alpha-chaconine, solanidine-N-oxide or IVC medium only. The results showed that the pre-implantation embryo development is inhibited by exposure to these glycoalkaloids. This effect is significant during the later pre-implantation embryo development period as indicated by fewer numbers of expanded and hatched blastocysts produced in the media containing these alkaloids. Therefore, we conclude that in vitro exposure of oocytes and fertilized ova to the steroidal glycoalkaloids from potatoes inhibits pre-implantation embryo development. Furthermore, we suggest that ingestion of Solanum species containing toxic amounts of glycoalkaloids may have negative effects on pre-implantation embryonic survival.

We investigated the source of the C and N flush that occurs upon rewetting of dry soil, and whether it is from microbial death and/or aggregate destruction. A moderately well drained Kennebec silt loam (Fine-silty, mixed, superactive, mesic Cumulic Hapludoll) was sampled to a 10 cm depth. Soil under constant water content (CWC) was compared with soil subjected to a series of four dry-wet (DW) cycles during the experimental period (96 d) and incubated at 25 C. Mineralized C and N were measured during the drying and rewetting periods. Aggregate size distributions were studied by separating the soil into four aggregate size classes (>2000, 250-2000, 53-250, and 20-53 mu m) by wet sieving. Repeated DW cycles significantly reduced cumulative N mineralization compared with CWC. The reduction in cumulative mineralized C resulting from DW compared with CWC increased as the DW treatments were subjected to additional cycles. The flush of mineralized C significantly decreased with repeated DW cycles. There was no significant effect on aggregate size distributions resulting from to the DW cycles compared with CWC treatment. Therefore, the flush of mineralized C and N seemed to be mostly microbial in origin in as much as aggregate distribution was unaffected by DW cycles.

In the present study, Inter-Simple Sequence Repeat-Polymerase Chain Reaction (ISSR-PCR) was utilized to estimate the population genetic structure of Gonatocerus ashmeadi (Girault) (Hymenoptera: Mymaridae), the predominant egg parasitoid of Homalodisca coagulata (Say) (Homoptera:Cicadellidae), the glassy-winged sharpshooter. Six populations from throughout the U.S. and a population from Argentina identified as near G. ashmeadi were analyzed. Four populations (California; San Antonio, Texas; Weslaco, Texas [WTX-2]; and Florida) were field collected and two (Louisiana and Weslaco, Texas [WTX-1]) were reared. Three ISSR-PCR reactions were pooled to generate 41 polymorphic markers among the six U.S. populations. Nei's expected heterozygosity values (h), including the reared population from Louisiana, were high (9.01-14.3%) for all populations, except for a reared population from WTX-1 (2.9%). The total genetic diversity value (Ht) for the field populations was high (23%). Interestingly, the Florida population that was collected from one egg mass (siblings) generated the greatest number of polymorphic markers (20) and was observed with the highest gene diversity value (14.3%). All populations, except WTX-2 generated population-specific markers. Comparison of genetic differentiation estimates, which evaluate the degree of genetic subdivision, demonstrated good agreement between G sub(ST) and [thetas] values, 0.38 and 0.50, respectively for field populations, and 0.44 and 0.50, respectively for all populations. Genetic divergence (D) indicated that the WTX-1 population was the most differentiated. Average D results from the Argentina population support the taxonomic data that it is a different species. The present results estimate the population genetic structure of G. ashmeadi, demonstrating genetic divergence and restricted gene flow (Nm = 0.83) among populations. These results are of interest to the Pierce's disease/glassy-winged sharpshooter biological control program because the key to successful biological control may not be in another species, but instead in different geographic races or biotypes.

The purpose of these burns is to restore shortleaf pine (Pinus echinata Miller)/mixed-oak forests with more diverse understories, which include native bluestem grasses (Andropogon gyrans Ashe and Schizachyrium scoparium (Michx.) Nash). Although burning might be an effective tool for restoring these stands to a shortleaf pine/mixed-oak/bluestem grass community type, it is not known whether these restoration burns will have a negative impact on water quality. Six subwatersheds (similar in vegetation, soil type, stream size and location, and disturbance history) were located within the Conasauga River Watershed. Four of the sites were burned in Mar. 2001, and two sites were designated as controls. To evaluate initial effects of prescribed burning on water quality, we measured soil solution and streamwater nutrient concentrations and streamwater sediment concentration (TSS; total suspended solids) weekly over a 10-month period. Consistent with goals of the land managers, all the prescribed fires resulted in low- to moderate-intensity and low-severity fires. Soil solution and streamwater NO super(-) sub(3)-N and NH super(+) sub(4)-N did not increase after burning on any of the sites. We found no differences in TSS between burn and control streams in any of the sample periods. In addition, we found no detectable differences between control and burned sites for concentrations of PO super(3) sub(4) super(-), SO super(2) sub(4) super(-), Ca super(2+), Mg super(2+), K super(+), or pH in soil solution or streamwater. Thus, these prescribed restoration fires did not have a significant effect on soil solution and stream chemistry or stream sediment (TSS) concentrations.

Under outbreak conditions, Mormon crickets often form large cohesive migratory bands that can contain millions of individuals moving in unison across the landscape. Density-dependent phase polyphenism has been hypothesized as a behavioural mechanism underlying Mormon cricket band formation and movement based largely on the similarity between bands of Mormon crickets and those of migratory locusts. I tested this hypothesis by quantifying the effects of long-term differences in rearing density versus the short-term presence or absence of conspecifics on Mormon cricket movement behaviour across three different developmental stages. Rearing density and the presence of conspecifics both influenced Mormon cricket movement, but in distinctly different ways. Increases in the expression of walking-related behaviours were mainly induced by the short-term presence of conspecifics. The longer-term effects of high rearing density primarily influenced only turning-related behaviours. Developmental variation in activity levels was observed and indicates that developmental stage should be an important consideration in future analyses of Mormon cricket movement. Overall, these results suggest that interindividual interactions play a greater role in inducing the movement of migratory band-forming Mormon crickets than do endogenous behavioural-phase changes mediated by high local rearing density.

The proteins used in these experiments are the ones in commercially available Bollgard and Bollgard II cotton. Both bollworms and tobacco budworms selectively fed on nontreated diet compared with diet treated with Cry1Ac. In addition, bollworms exhibited a concentration response with Cry1Ac. In general, bollworms selected diet with low concentrations of Cry1Ac compared with diet with higher concentrations of Cry1Ac. For Cry2Ab, the avoidance was not as prominent as that observed for Cry1Ac. Based on results from no-choice assays, the Cry1Ac and Cry2Ab concentrations used in choice assays represented a wide range of biological activity on both species. The lower concentrations provided low levels of mortality, whereas the higher concentrations provided high levels of mortality. Also, the developmental times of larvae were longer at higher concentrations of both proteins. These data provide important information about the behavioral response of key cotton pests to the B. thuringiensis proteins found in commercially available transgenic cotton. This information will be important to develop accurate scouting and management procedures for Bollgard and Bollgard II cotton.

Male capture was inversely related to height of traps over the four heights tested (0, 20, 60, and 100 cm). Captures increased with increasing pheromone load over the doses of 0, 100, 300, and 600 mu g, but captures at the highest load, 1,000 mu g, were not significantly different from 300 or 600 mu g. H. equina captures were strongly diurnal, with a flight period spanning approximately 6 wk starting in mid-June. Vane color of traps (white, yellow, green, blue, red, black) did not affect H. equina capture but significantly influenced capture of nontargets, including pollinators. A bucket trap with the funnel opening at 20 cm, and green (or red) vanes, baited with 600 mu g of 2-tetradecanone, was the optimal design for high male capture and low nontarget capture. The low-cost capture of over 50,000 H. equina on a 2.4-ha commercial bog in Massachusetts with this lure-trap combination indicates the feasibility of mass trapping for managing established infestations of H. equina.

This study was initiated to more fully characterize the role of structure, sanitation, and trap location on capture of T. castaneum in pheromone-baited pitfall traps commonly used in insect monitoring programs. Food patches, spatial structure, and trap position were manipulated in pilot scale warehouses with a known density of insects. Significantly greater quantities of insects were captured in traps placed in warehouses without food patches than those with food patches. Insects tended to be captured with greater frequency in the corners and underneath shelves than in the middle of warehouses. Correlation between actual density and trap captures was stronger in warehouses without food patches, suggesting that sanitation is an important part of pest monitoring. Finally, placement of concrete blocks in the middle of the warehouse did not increase the number of beetles captured in that area compared with warehouses without concrete blocks. Results from this study should be considered when developing guidelines for trap interpretation.

Three types of enclosure were used: complete exclusion enclosures, partial exclusion enclosures that permitted entry by parasitic Hymenoptera, and environmental exclusion enclosures that reduced the effects of wind and rain on Russian wheat aphids and trapped emigrating alate Russian wheat aphids so that they could not return to plants within the enclosure. Russian wheat aphids in nonenclosed plots were also studied. Russian wheat aphid density varied among treatments in the following order: complete exclusion greater than or equal to partial exclusion > environmental exclusion > nonenclosed plots. The trapping of alatae within enclosures and reduced adverse stresses such as rain and wind within enclosures were partially responsible for the greater Russian wheat aphid density in complete and partial exclusion enclosures compared with environmental exclusion enclosures and nonenclosed plots. The aphidophagous coccinellid, Hippodamia convergens Guerin-Meneville, and the generalist Nabis spp. were the most abundant predators during the increasing phase of Russian wheat aphid population development, but they did not substantially reduce Russian wheat aphid numbers. H. convergens, Coccinella septempuntata L., and H. sinuata Mulsant were the most abundant predators during the declining phase of Russian wheat aphid population growth. The dominant parasitoid was Lysiphlebus testaceipes (Cresson), but parasitism rates were very low. Canonical correspondence analysis showed close associations between the abundance of predators and Russian wheat aphid density, Russian wheat aphid density and wind during the increasing phase of Russian wheat aphid population development, and Russian wheat aphid density and rainfall late in the growing season.

RESEARCH METHODS AND PROCEDURES: Members of the Multidisciplinary Care Task Group conducted searches of MEDLINE and PubMed for articles related to WLS in general and medical and nutritional care in particular. Pertinent abstracts and literature were reviewed for references. Multiple searches were carried out for various aspects of multidisciplinary care published between 1980 and 2004. A total of 3000 abstracts were identified; 242 were reviewed in detail. RESULTS: We recommended multidisciplinary screening of WLS patients to ensure appropriate selection; preoperative assessment for cardiovascular, pulmonary, gastrointestinal, endocrine, and other obesity-related diseases associated with increased risk for complications or mortality; preoperative weight loss and cessation of smoking; perioperative prophylaxis for deep vein thrombosis and pulmonary embolism (PE); preoperative and postoperative education and counseling by a registered dietitian; and a well-defined postsurgical diet progression. DISCUSSION: Obesity-related diseases are often undiagnosed before WLS, putting patients at increased risk for complications and/or early mortality. Multidisciplinary assessment and care to minimize short- and long-term risks include: comprehensive medical screening; appropriate pre-, peri-, and postoperative preparation; collaboration with multiple patient care disciplines (e.g., anesthesiology, pulmonary medicine, cardiology, and psychology); and long-term nutrition education/counseling.

Open-top chambers exposed trees to ambient or ambient plus 200 mu mol mol super(-1) atmospheric CO sub(2) for 31 months. Tank CO sub(2) was depleted in atmospheric super(13)C; foliage of elevated CO sub(2) trees had delta super(13)C of -42.9, compared with -29.1 for ambient CO sub(2) trees. Roots 1 m from the base of elevated CO sub(2)-grown trees had more negative delta super(13)C relative to control trees, and this difference was detected, on average, up to 5.8, 3.7 and 3.7 m away from the trees for 0-2, 2-5 and >5 mm root-size classes, respectively. Non-fertilized tree roots extended as far as fertilized trees despite the fact that their above-ground biomass was less than half that of fertilized trees. These results are informative with respect to root sampling intensity and protocol, and the distances required between experimental manipulations to evaluate below-ground processes of independent treatments. Fine-root turnover has usually been estimated to range from weeks to 3 years, representing a major avenue of carbon flux. Using a mixing model we calculated that 0-2 mm roots had a mean residence time of 4.5 years indicating relatively slow fine-root turnover, a result that has major implications in modelling C cycling.

Methods and Results:Serial passage on ampicillin ( beta -lactam) enriched modified Hsu-Shotts medium resulted in a F. columnare mutant that differed from the parent strain in colony morphology, whole cell proteins, adhesion and virulence. The mutant differed from its parent in virulence during immersion challenge, but not during injection challenge or generation of antibodies. Conclusion:Flavobacterium columnare exposure to ampicillin produces both resistance to that antibiotic and produces mutants that lack or have reduced adhesion characteristics and modified ability to adhere to fish tissue. Significance and Impact of the Study:This is the first description of an adhesion-defective mutant of F. columnare and the effects of altered adhesion on columnaris disease. This mutant has considerable potential as a tool to study the role of adhesion in columnaris disease.

Inhibition can be overcome and sensitivity increased by culturing bacteria on agar media prior to PCR (termed BIO-PCR). However, Xylella fastidiosa grows slowly, requiring 10-14 days for visible colonies to appear. In this study an agar-absorption BIO-PCR method for detecting X. fastidiosa in grape and citrus plants was developed. Optimum lengths of time for absorption of inhibitors by the agar medium or enrichment of bacteria on the medium were determined for Pierce's disease of grape and citrus variegated chlorosis. When petioles of grape and citrus leaves with symptoms were spotted onto agar media, the spots washed after various time intervals and assayed for X. fastidiosa by real-time PCR, 97% (31 out of 32) and 100% (six out of six) of spots were positive after 2 days and 4 h for grape and citrus, respectively. With direct PCR, only 12.5% (four out of 32) and 33% (two out of six) of spots were positive, respectively, and visible X. fastidiosa colonies were evident after 10 and 14 days, respectively. In a separate experiment with samples from a different vineyard, 46% (13 out of 28) of the grape samples (agar spots) were positive after 1 day and 93% (26 out of 28) after 5 days using agar-absorption PCR. In contrast, all samples were negative by direct PCR. Viable X. fastidiosa were recovered from all samples after 14 days. Further tests with eight randomly selected grape petioles from three Texas vineyards known to have Pierce's disease resulted in 50% being positive by a simple 24 h agar-absorption PCR assay, whereas none was positive by direct PCR. Overall, 10 out of 16 (63%) vines from five vineyards (two in California and three in Texas) were positive after the 24 h agar-absorption PCR assay. In contrast, only one vine was positive by direct PCR. This simple agar absorption-based PCR assay protocol should prove useful for the routine detection of X. fastidiosa and other slow-growing bacteria in the presence of PCR inhibitors.

Herbaceous cover was irregularly distributed, with high cover zones in distinct bands across slopes on paddocks in stable and degrading condition, and irregular patches in a degraded paddock. Size and density of these zones declined with paddock condition, as native perennial tussock grasses were lost and replaced by an exotic stoloniferous grass. Describing disturbance responses of herbaceous cover in this community requires sampling at multiple spatial scales.

On federal forest lands in the Pacific Northwest, standards and guidelines for green-tree retention have been adopted, but systematic assessments of eco-system response have not been undertaken. We studied initial (1-2 yr) responses of vascular understory communities to green-tree retention at six locations (blocks) in western Oregon and Washington, using a factorial design with retention at contrasting levels (15% vs. 40% of initial basal area) and spatial patterns (trees dispersed vs. aggregated in 1-ha patches). Direction of compositional change (expressed in ordination space) was similar among treatments within each block, but the magnitude of change was consistently larger at 15% than at 40% retention; pattern of retention had little effect on compositional change. Despite major changes in vegetation structure, early-seral (ruderal) herbs contributed little to plant abundance and richness in most treatments. For many forest understory groups, declines in abundance or richness were significantly greater at 15% than at 40% retention. However, pattern of retention had surprisingly little effect on treatment-level response; although changes within forest aggregates were small, declines in adjacent areas of harvest were generally greater than those in corresponding dispersed treatments. Late-seral herbs were particularly sensitive to these effects, with more frequent extirpations from plots within the harvested portions of aggregated treatments than from dispersed treatments. Plot-to-plot variation in understory abundance and richness within treatments increased after harvest, but level and pattern of retention had little effect on the magnitude of this change. We suspect that the initial responses of forest understories to green-tree retention are mediated, in large part, by associated patterns of disturbance and slash accumulation that differ significantly with level and pattern of retention. Because these represent short-term responses, future sampling will be necessary to understand the broader implications of structural retention harvests. We predict that, as effects of disturbance diminish with time, effects of canopy structure will increasingly shape patterns of compositional and structural development in the understory.

The nucleotide sequences of the entire gyrA, gyrB, parC, and parE genes of 42 mutants were determined. DNA gyrase was the primary target for each fluoroquinolone, and topoisomerase IV was the secondary target. Most mutations appeared in the quinolone resistance-determining regions of gyrA (resulting in changes of Asp-87 to Tyr or Gly-81 to Cys) and parC (resulting in changes of Asp-93 or Asp-88 to Tyr or Ser-89 to Ile); only two mutations were found in gyrB, and only two mutations were found in parE. More mutants with multiple gyrA and parC mutations were produced with gatifloxacin than with the other fluoroquinolones tested. Allelic diversity was observed among the resistant mutants, for which the drug MICs increased 2-to 256-fold. Both the structures of the drugs and their concentrations influenced the selection of mutants.

Nitrous oxide efflux from N fertilized soils has been modeled using NO sub(3) super(-) content with a limited success, but predicting N sub(2)O production in non- fertilized soils has proven to be much more complex. The present study investigates the contribution of soil amino acid (AA) mineralization to N sub(2)O flux from semi-arid soils. In laboratory incubations (-34 kPa moisture potential), soil mineralization of eleven AAs (100 mu g AA-N g super(-1) soil) promoted a wide range in the production of N sub(2)O (156.0[plus-or-minus- sign]79.3 ng N sub(2)O-N g super(-1) soil) during 12 d incubations. Comparison of the delta super(13)C content of the individual AAs and the delta super(13)C signature of the respired AA-CO sub(2)-C determined that, with the exception of TYR, all of the AAs were completely mineralized during incubations, allowing for the calculation of a N sub(2)O-N conversion rate from each AA. Next, soils from three different semi-arid vegetation ecosystems with a wide range in total N content were incubated and monitored for CO sub(2) and N sub(2)O efflux. A model utilizing CO sub(2) respired from the three soils as a measure of organic matter C mineralization, a preincubation soil AA composition of each soil, and the N sub(2)O-N conversion rate from the AA incubations effectively predicted the range of N sub(2)O production by all three soils. Nitrous oxide flux did not correspond to factors shown to influence anaerobic denitrification, including soil NO sub(3) super(-) contents, soil moisture, oxygen consumption, and CO sub(2) respiration, suggesting that nitrification and aerobic nitrifier denitrification could be contributing to N sub(2)O production in these soils. Results indicate that quantification of AA mineralization may be useful for predicting N sub(2)O production in soils.

This immunological inefficiency enables pathogens such as Salmonella enterica serovar Enteritidis (SE) to invade and colonize the visceral organs of immature chickens. The objective of this study was to evaluate the effect of purified beta -glucan as an immunomodulator of the innate immune response. beta -glucan, as a feed additive, significantly provided protection against SE organ invasion in young chickens (P<0.05). The functional efficiency of heterophils isolated from neonatal chickens fed a beta -glucan ration was significantly (P<0.05) up-regulated when compared to heterophils isolated from chickens fed a control ration as determined with an array of functional assays. Phagocytosis, bactericidal killing, and oxidative burst were significantly increased in heterophils isolated from chickens fed the purified beta -glucan ration (P<0.05). To our knowledge, this is the first report of a purified beta -glucan feed additive significantly decreasing the incidence of SE organ invasion in immature chickens and up-regulating the functional abilities of heterophils isolated from immature chickens against an invading pathogen, SE.

Additionally, six different culture media were compared to determine maximum patulin production. Eleven different strains of Penicillium species were selected because they had previously been reported to be producers of patulin. The strains included Penicillium expansum, Penicillium griseofulvum (formerly Penicillium urticae), Penicillium clavigerum, and Penicillium coprobium and a recent Penicillium sp. isolated from an apple. Cultures were grown in duplicate in three different liquid media: potato dextrose, malt extract, and glucose/yeast extract/peptone, both with and without manganese supplementation. Patulin production was compared at 24, 48, 72, and 96 h. Variability in patulin production occurred among the different species, growth media used, and time of incubation. All three of the P. griseofulvum isolates were the highest producers of patulin at 96 h. For most of the strains, potato dextrose broth supplemented with manganese was optimal for maximum production of patulin. Although P. expansum is frequently cited as the most likely source of patulin in apple juice, certain other Penicillium species are capable of producing more patulin than strains of P. expansum. The apple juice industry should be alert to the possibility that Penicillium species other than P. expansum can be responsible for the occurrence of patulin.

In this study, growth characteristics (generation time, lag phase duration, and maximum population), pH at stationary phase, and survival characteristics (level of attachment and survival on apple surfaces, resistance to hydrogen peroxide decontamination treatments, and thermal resistance at 60 degree C) of 15 nonpathogenic generic Escherichia coli strains and one nonpathogenic E. coli O157:H43 strain were compared with those of two E. coli O157:H7 strains and two Salmonella strains. Few differences in growth characteristics or pH at stationary phase were evident between nonpathogenic and pathogenic strains tested. However, considerably more separation among strains was seen following investigation of survival characteristics. E. coli ECRC 97.0152, which does not contain genes encoding for known virulence factors associated with E. coli O157:H7, appears to be a good surrogate candidate, with growth and survival characteristics similar to those of E. coli O157:H7 strains. The less heat-resistant surrogate strains E. coli NRRL B-766 and NRRL B-3054 and E. coli ATCC 11775, ATCC 25253, and ATCC 25922 may be used when attempting to model the heat resistance of Salmonella Montevideo G4639 and Salmonella Poona RM 2350, respectively. These surrogate strains may be useful for evaluating the efficacy of intervention steps in reducing populations of selected strains of E. coli O157:H7 and Salmonella in processing environments where these pathogens cannot be introduced.

It first requires the feeding of an initiating insect scale and is only fully developed when scale-altered bark becomes infected by one of two Neonectria species. In Ohio, there was a 19-year lag between discovery of the initiating scale insect and the development of BBD. In September 1984, the BBD-initiating scale (Cryptococcus fagisuga Lind) was discovered in the Holden Arboretum, Geauga County, OH. Nineteen years later (December 2003), A. Iskra discovered the exotic BBD-causing fungus, Neonectria coccinea (Pers.:Fr.) Rossman & Samuels var faginata Lohman, Watson & Ayers, on American beech (Fagus grandifolia Ehrh.) in the Holden Arboretum. In 1934, Erlich reported that there was normally a delay of at least 1 year between the appearance of the scale and the first appearance of the Neonectria spp. fungus. In the years immediately after the first report of the scale in Ohio, pathologists and arboretum staff made frequent visits to the site in an attempt to find Neonectria spp. fruiting. After a decade of searching, these visits became more infrequent. However, it was on one of these visits that A. Iskra found the fungus. He found it on only four trees, none of which had the extensive bark cankering common in chronic Neonectria spp. infections. In North America, the two species of Neonectria that have been involved in BBD mortality are the native N. galligena (Bres.) Rossman & Samuels, or the exotic N. coccinea var faginata. In the absence of beech scale infestations, reports of the native N. galligena infecting American beech are few. Yet, in West Virginia, western Pennsylvania, Michigan, and possibly North Carolina, the fungus first associated with the killing front has been the native N. galligena and not the exotic variety, N. coccinea var faginata. To our knowledge, this is the first report of BBD in Ohio and it is unique because the associated fungus is the exotic variety.

To identify the etiologic agent of the disease, single-spore cultures were established from intercepted fruit and were characterized by pathogenicity to wounded fruit, morphology, and sporulation pattern on three agar media, random amplified polymorphic DNA fragment pattern analysis, and species-specific polymerase chain reaction (PCR). These data indicated that the disease likely was caused by more than one species of Alternaria, and that none of the isolates from intercepted Ya Li fruit was A. alternata or A. gaisen. A species-specific PCR assay for A. gaisen demonstrated that no isolate from Ya Li was A. gaisen. A PCR assay for the AMT gene demonstrated that no isolate from Ya Li was A. `mali'. Because of these data and the absence of a description to accommodate at least one of the taxa involved, A. yaliinficiens R. G. Roberts sp. nov. is described, and the disease caused by this and other species of Alternaria on Ya Li pear from China is referred to as "chocolate spot of Ya Li pear" to distinguish it from black spot of Japanese pear.

Previously, we have shown that hepatic SAM is decreased and/or S-adenosylhomocysteine increased in arsenic-deprived rats; these rats tended to have hypomethylated DNA. To determine the effect of dietary arsenic on dimethylhydrazine (DMH)-induced aberrant crypt formation in the colon, Fisher 344 weanling male rats were fed diets containing 0, 0.5, or 50 mu g As (as NaAsO sub(2))/g. After 12 wk, dietary arsenic affected the number of aberrant crypts (p<0.02) and aberrant crypt foci (p<0.007) in the colon and the amount of global DNA methylation (p<0.04) and activity of DNA methyltransferase (DNMT) (p<0.003) in the liver. In each case, there were more aberrant crypts and aberrant crypt foci, a relative DNA hypomethylation, and increased activity of DNMT in the rats fed 50 mu g As/g compared to those fed 0.5 mu g As/g. The same phenomenon, an increased number of aberrant crypts and aberrant crypt foci, DNA hypomethylation, and increased DNMT tended to hold when comparing rats fed the diet containing no supplemental arsenic compared to rats fed 0.5 mu g As/g. The data suggest that there is a threshold for As toxicity and that possibly too little dietary As could also be detrimental.

To that end, we used a simulation model to investigate three questions about behavioral tradeoffs that dispersing animals might face: (i) speed of movement against risk of predation, (ii) speed of movement against foraging, and (iii) perceptual range against risk of predation. The first investigation demonstrated that dispersing animals can generally benefit by slowing from maximal speed to perform anti-predatory behavior. The optimal speed was most strongly influenced by the disperser's energetic reserves, the risk of predation it faced, the interaction between these two parameters, and the effectiveness of its anti-predatory behavior. Patch arrangement and the search strategy employed by the dispersers had marginal effects on this tradeoff relative to the above parameters. The second investigation demonstrated that slowing movement to forage during dispersal may increase success and that optimum speed of dispersal was primarily a function of the dispersing animal's energetic reserves, predation risk, and their interaction. The richness (density of food resources) of the interpatch matrix and the patch arrangement had relatively minor impacts on how much time a dispersing animal should spend foraging. The final investigation demonstrated animals may face tradeoffs between dispersing under conditions that involve a low risk of predation but limit their ability to perceive distant habitat (necessitating more time spent searching for habitat) and conditions that are inherently more risky but allow animals to perceive distant habitat more readily. The precise nature of this tradeoff was sensitive to the form of the relationship between predation risk and perceptual range. Our overall results suggest that simple depictions of these behavioral tradeoffs might suffice in spatially explicit population models.

DNA-based methodologies, such as randomly amplified polymorphic DNA (RAPD) analysis, have been playing key roles in genetic information collection of the bacterium. This study further analyzed the nucleotide sequences of selected RAPDs from X. fastidiosa strains in conjunction with the available genome sequence databases and unveiled several previously unknown novel genetic traits. These include a sequence highly similar to those in the phage family of Podoviridae. Genome comparisons among X. fastidiosa strains suggested that the 'phage' is currently active. Two other RAPDs were also related to horizontal gene transfer: one was part of a broadly distributed cryptic plasmid and the other was associated with conjugal transfer. One RAPD inferred a genomic rearrangement event among X. fastidiosa PD strains and another identified a single nucleotide polymorphism of evolutionary value.

One simple method for evaluating these impacts is to combine flow duration curves with regression relations between surface-water chemical concentrations (C) and instantaneous discharge (Q). However, little is known regarding the drainage basin-scale effects of mining and reclaiming drainage basins on regression relations. These effects were assessed on three small experimental drainage basins in Ohio subjected to surface mining for coal. Comparisons were made between regression parameter changes for natural/ undisturbed conditions, land disturbances caused by mining and reclamation, incomplete reclamation, and the final condition of the reclaimed drainage basins. Regression analysis used a total of 5047 laboratory analyses of 36 constituents. Of 429 regressions, 153 (36%) were statistically significant. Knowledge of changes in regression parameters is important because regressions supply information on the rate of release and supply of chemical constituents in mined and reclaimed drainage basins. Duration curves of concentration and loads can be constructed using these regressions with flow-duration curves to give estimates of the percentage of time that concentrations and loads are exceeded during different phases of disturbance. This study assessed the changes in regression relations due to mining coal seams and reclamation activities for 36 chemical constituents, two mining methods, three reclamation practices and three distinct geologic settings.

Expression of several LEE-encoded genes, which are organized into operons LEE1 through LEE5, is under the positive regulation of ler, the first gene in the LEE1 operon. We have recently demonstrated that EHEC O157:H7 lacking hha exhibited greater than a 10-fold increase in ler expression and that the repression of ler results from the binding of Hha to the ler promoter. In this report, we show that an hha mutant of EHEC O157:H7 exhibited increased adherence to Hep-2 cells, had increased transcriptional activities of LEE1, LEE2, LEE3, and LEE5 as determined by reverse transcriptase-polymerase chain reaction assays, and expressed LEE5::lac transcriptional fusion at levels that were several-fold higher than that expressed by the parental hha super(+) strain. These results demonstrate that hha is an important regulatory component of the cascade that governs the expression of LEE operons and the resulting ability of EHEC O157:H7 to intimately adhere to host cells.

We synthesize research from the fields of ecology and hydrology to address the issue of deep drainage in arid and semiarid regions. We start with a recently developed hydrological model that accurately simulates soil water potential and geochemical profiles measured in thick (>50 m), unconsolidated vadose zones. Model results indicate that, since the climate change that marked the onset of the Holocene period 10 000-15 000 years ago, there has been no deep drainage in vegetated interdrainage areas and that continuous, relatively low (<-1 MPa) soil water potentials have been maintained at depths of 2-3 m. A conceptual model consistent with these results proposes that the native, xeric-shrub-dominated, plant communities that gained dominance during the Holocene generated and maintained these conditions. We present three lines of ecological evidence that support the conceptual model. First, xeric shrubs have sufficiently deep rooting systems with low extraction limits to generate the modeled conditions. Second, the characteristic deep-rooted soil-plant systems store sufficient water to effectively buffer deep soil from climatic fluctuations in these dry environments, allowing stable conditions to persist for long periods of time. And third, adaptations resulting in deep, low-extraction-limit rooting systems confer significant advantages to xeric shrubs in arid and semiarid environments. We then consider conditions in arid and semiarid regions in which the conceptual model may not apply, leading to the expectation that portions of many arid and semiarid watersheds supply some deep drainage. Further ecohydrologic research is required to elucidate critical climatic and edaphic thresholds, evaluate the role of important physiological processes (such as hydraulic redistribution), and evaluate the role of deep roots in terms of carbon costs, nutrient uptake, and whole-plant development.

To identify the factors governing the persistence of chloramphenicol resistance in the absence of specific selection pressure, the location of the chloramphenicol resistance gene cmlA and its linkage to other resistance determinants were investigated. Southern blot analysis of plasmid DNA from 46 swine E. coli isolates indicated that cmlA was present on large plasmids greater than 100 kbp. Fifty-two percent of the isolates were able to transfer chloramphenicol resistance to an E. coli recipient at conjugation frequencies ranging from 10 super(-) super(3) to 10 super(-) super(8) per recipient. Antimicrobial susceptibility tests on transconjugant strains demonstrated that resistance to sulfamethoxazole, tetracycline, and kanamycin frequently transferred along with chloramphenicol resistance. The transconjugant strains possessed at least two distinct class 1 integrons that linked cmlA to both aminoglycoside resistance genes aadA1 and aadA2 and either to sul1 or to sul3 sulphonamide resistance genes. These results suggest that in the absence of specific chloramphenicol selection pressure, the cmlA gene is maintained by virtue of gene linkage to genes encoding resistance to antimicrobials that are currently approved for use in food animals.

A number of management methods that might increase soil C levels have been suggested, but there are scant available data to properly support recommendations or policy changes. We have used eddy covariance measurements of net ecosystem exchange (NEE) in contrasting management systems to discern the impact of two specific practices, reduced tillage and a spring cover crop in the soybean year, on the biennial C balance of a corn/soybean rotation, the dominant cropping system in much of the midwestern United States. Measurements commenced in fall 2001, immediately following corn harvest and tillage, and continued through a year of soybean and a year of corn. One of the two fields was farmed conventionally (CONV), with fall chisel/disk tillage after each harvest, soybean planting in late May (2002), and corn planting in early May (2003). In the alternative field (ALT), we used reduced tillage (strip till) each fall following harvest, and a spring oats cover crop in the soybean year (2002) that was planted in early April, then killed with a herbicide shortly after soybean planting. Both fields have the same soil type, and were similarly instrumented, with a sonic anemometer and open-path infrared gas analyzer. Reduced tillage resulted in somewhat lower soil respiration rates in both autumns in ALT, relative to CONV. Also, the spring oats cover crop prior to soybean did fix additional C, but it was rapidly respired after the oats were killed, and the surface crop residue slowed the initial development of the subsequent soybean crop. Soybean yields for the two fields were similar, but slightly higher for CONV, a pattern that was more pronounced with corn the following year. Overall, cumulative NEE was larger (more C fixed) in the conventional field, but C removed in yield in the conventional field was larger too, so that the apparent change in soil organic carbon (SOC), estimated as NEE-harvested C, in the two fields was nearly identical. In both treatments the apparent SOC was negative (approximately 90 g C m super(-2) SOC lost over the biennium, or about 20% of cumulative NEE) but this may be at least partially due to systematic underestimation by eddy covariance rather than an actual loss of SOC. We conclude that neither of these management practices (reduced tillage, spring cover crop) resulted in any C sequestration within the first two years of implementation that is resolvable with current measurement methods.

Because of their middle position in many food webs they may be useful indicators of trophic complexity and dynamics. However, reliable data on snake populations are rare due to the challenges of sampling these patchily distributed, cryptic, and often nocturnal species and also due to their underrepresentation in the ecological literature. Studying a diurnally active stream-associated population of garter snakes has allowed us to avoid some of these problems so that we could focus on issues of sampling design and its influence on resulting demographic models and estimates. From 1986 to 2001, we gathered data on a population of the Pacific coast aquatic garter snake (Thamnophis atratus) in northwestern California by conducting 3-5 surveys of the population annually. We derived estimates for sex-specific survival rates and time-dependent capture probabilities using population analysis software and examined the relationship between our calculated capture probabilities and variability in sampling effort. We also developed population size and density estimates and compared these estimates to simple count data (often used for wildlife population monitoring). Over the 16-yr period of our study, we marked 1730 snakes and had annual recapture rates ranging from 13% to 32%. The best approximating demographic model for our data demonstrated higher survival rates for females than males and showed low and annually variable capture probabilities for both. Annual population size estimates (converted to linear densities), ranged from 58 to 131 snakes/km. Mean annual field counts typically accounted for only 5-10% of the total population size estimated using capture-recapture models. We found no evidence for a changing population size throughout the study. We found a positive relationship between sampling effort and capture probabilities. We evaluate survey design options that would help us approach recommended levels of capture probabilities and thus increase the precision of our estimates, allowing derivation of more complex demographic models. Our results should be useful in the development of monitoring programs for snakes and other secretive wildlife species and provide target demographic rate values for restoration of related at-risk snake species.

Four of the plants were confirmed to carry the CP gene in the sense orientation of the gene and seven plants in the AS orientation. Two of the CP plant lines and all of the AS lines showed DNA rearrangements of the transgene in addition to an intact copy of the transgene. The copy number ranged from one to nine. Of the 11 lines, eight had only one to four copies of the transgene. Transcription of the transgene occurred for three of the CP lines and five of the AS lines as determined by Northern hybridization. All 11 plant lines were challenged with BYMV using controlled aphid transmission. One month following aphid transmission, the transgenic plants were examined by immunoelectron microscopy for presence of the virus. Several transgenic plant lines containing either antiviral transgene showed a lower incidence of infection (percentage of plants infected as detected by immunoelectron microscopy) than the non-transformed plants. Most of the CP- and AS-transgenic plants that did not contain BYMV 1 month after challenge were found to contain BYMV the next season. It appeared that BYMV infection was delayed in the CP- and AS-transgenic lines but that the transgenes did not prevent eventual infection of BYMV. This is the first report of developing a floral bulb crop with antiviral genes to BYMV.

We evaluated susceptibility of genetically distinct lines of broilers to systemic Salmonella enteritidis (SE) infections. SE was administered into the abdomen of day-old chickens (parental lines [A and B]; F1 reciprocal crosses [C and D]) to assess modulation of leukocytes and survivability of chickens. Line A was more resistant to SE than line B; likewise cross D was more resistant than cross C. Significantly more heterophils migrated to the abdominal cavity post-infection in the resistant lines. These data indicate that increased heterophil influx to the infection site contributes to increased resistance against systemic SE infections in neonatal chickens.

Disturbed cotton aphids, Aphis gossypii Glover, released (E)- beta -farnesene into the air as detected by solid phase microextraction and gas chromatography mass spectrometry (GC-MS). Solvent extracts of cotton aphids of various life stages and weights also were analyzed by GC-MS for sums of ions 69 and 93, which discriminated (E)- beta -farnesene from coeluting compounds. Aphids of all life stages and sizes reared on cotton plants in both an environmental chamber and glasshouse contained (E)- beta -farnesene in amounts ranging from 0.1 to 1.5 ng per individual. The quantities of (E)- beta -farnesene in aphids increased in relation to increasing body weight, and variation in individual weights explained about 82% of the variation in alarm pheromone. However, the concentrations (ng/mg fresh weight) declined exponentially with increasing body weight. These findings indicate that aphid nymphs try to compensate for their smaller size by producing relatively more pheromone per weight than adults but still cannot approach an evolutionary optimal load, as assumed in adults with the greatest total amounts. This suggests that young aphids need to balance costs of growth and maturation with costs of producing the alarm pheromone.

(Hemiptera: Pentatomidae). Parasitism of C. blackburniae eggs, nymphs and adults by biocontrol agents was quantified across a wide range of habitats and compared to other sources of mortality. Egg mortality due to the biocontrol agent Trissolcus basalis Wollaston (Hymenoptera: Scelionidae) was low (maximum 26%) and confined to elevations below 500 m on a single host plant. Predation, mainly by alien spiders and ants, was the greatest source of egg mortality (maximum 87%). Parasitism of adult C. blackburniae by the biocontrol agent Trichopoda pilipes (F.) (Diptera: Tachinidae) was near zero at 21 of 24 sites surveyed. Three sites with high bug density had higher levels of T. pilipes parasitism, reaching maxima of 70% among adult female bugs, 100% among males and 50% among fifth instars. Male-biased parasitism indicated that T. pilipes is adapted to using male aggregation pheromone for finding C. blackburniae hosts. The relative impacts of biocontrol agents and other sources of mortality were compared using life tables. Invasive species, particularly generalist egg predators, had the greatest impacts on C. blackburniae populations. Effects of intentionally introduced parasitoids were relatively minor, although the tachinid T. pilipes showed potential for large impacts at individual sites. In retrospect, non-target attacks by biological control agents on C. blackburniae were predictable, but the environmental range and magnitude of impacts would have been difficult to foresee.

Evidence of matrix effects, factors that compromise the precision and accuracy of the ELISA, was present in assays with undiluted xylem fluid. These effects could be eliminated by dilution of extracts in water, resulting in a lower sensitivity of the assay of 4 mu g liter super(-1). In a field trial conducted in a commercial vineyard, there was an excellent correlation between Admire application rates and xylem fluid concentrations of imidacloprid. At an Admire application rate of 1.17 liter ha super(-1) (16 fl oz per acre), uptake of imidacloprid into vines was rapid. Imidacloprid was consistently detected in the xylem for up to 3 mo after application at concentrations known to be effective at managing populations of the sharpshooter Homalodisca coagulata Say, an important vector of Xylella fastidiosa Wells in California vineyards. The ELISA is a sensitive technique that can be used to study the behavior of systemic insecticides within crop systems and their impact on pest populations.

Merr., in fall 2001 and 2002 near Stoneville, MS, and Eudora, AR. A glass-vial bioassay was used to determine LC sub(50) values for the three species of stink bugs for the pyrethroids bifenthrin, cypermethrin, cyfluthrin, lambda -cyhalothrin, and permethrin, and the organophosphates acephate, dicrotophos, malathion, and methyl parathion. Results confirmed findings of other researchers that the brown stink bug was less susceptible to pyrethroid and organophosphate insecticides than were green and southern green stink bugs. The susceptibility of all three stink bug species to the insecticides tested was very similar at both test locations. The study established baseline insecticide mortality data from two locations in the mid-South for three stink bug species that are pests of soybean and cotton, Gossypium spp. Data from the tests are valuable for future use in studies on resistance and in resistance monitoring programs.

Drip laterals were spaced either in alternate furrows (2 m) or beneath every planted bed (1 m), and installation depths were either 0.2 or 0.3 m beneath the soil surface. Net return was gross return minus fixed and variable costs. Fixed costs included the annual payment for financing the initial investment of SDI materials and installation (5.00% interest over 10 years), the annual land lease, and the annual depreciation of the SDI system. Variable costs were those associated with cotton production and were similar for the two drip lateral spacings. Lint yield, seed mass, and gross and net returns were significantly greater for the 1 m lateral spacing in the first two seasons, but these parameters were significantly greater for the 2 m lateral spacing in the third season. These parameters were consistently greater (either numerically or significantly) for the 0.3 m lateral depth in all seasons. Most fiber quality parameters were not significantly different, and no consistent trends were observed. Lint yields ranged from 640 to 1,635 kg ha super(-1), and net returns ranged from -$395 to $1,005 ha super(-1). The low lint yield and resulting net loss were due to a germination failure in the second season for the alternate furrow spaced laterals.

The effects of using different DEM resolutions on watershed simulations and the ability to accurately predict sediment yield and runoff from different rainfall event sizes were studied using three application methods and data from six research watersheds. Simulating watersheds with a range of resolutions can help address the problem of deciding what topographic DEM resolution is ideal for model simulations of the watershed outlet, the end of each hillslope, and along the slope profiles. The three application methods studied here were: (1) Hillslope - Chanleng, (2) Hillslope - Calcleng, and (3) Flowpath. The two Hillslope methods use a representative slope profile to represent each hillslope in the watershed, and the Flowpath method uses all of the individual flowpaths as model input for WEPP simulations. Results show that the Hillslope methods were not significantly influenced by DEM resolutions; however, there was an observable interaction between resolutions and the Flowpath method. Large rainfall events were predicted better than small events, but fine DEM resolutions did not improve predictions of either large or small rainfall events. Using coarse DEM resolutions for the topographic input will not decrease the accuracy of erosion prediction using the WEPP model and the Hillslope methods, unless the coarseness of the DEM compromises the delineation of the watershed or hillslopes.

The objective of this study was to improve the capabilities of a basin-scale hydrologic simulation model for regional planning of irrigated agriculture. In this study, a Geographical Information System (GIS) based hydrological model, Soil and Water Assessment Tool (SWAT), was configured as a regional planning tool with a canal irrigation capability for estimating irrigation demand. The tool was capable of simulating hydrological processes associated with soil-plant-water interactions and capable of capturing the spatial and temporal variability of the major factors, which are important in regional planning. The tool was applied to the irrigation districts in the Lower Rio Grande Valley in Texas. It was validated for crop evapotranspiration and canal conveyance efficiency and applied to analyzing the demand and potential water savings of alternative water conservation measures. Estimated potential water savings were 234.2, 65.9, and 194.0 Mm super(3) for conservation measures related to on-farm management improvements, replacing sugarcane with corn, and improving canal conveyance efficiency, respectively. Results indicated that on-farm management measures might be as beneficial as improving canal conveyance systems. The planning tool (with hydrological modeling and GIS capabilities) and estimations made would be useful for regional planners and irrigation district managers. The tool could be used for other irrigation systems as well.

A novel device was developed for high-concentration measurements. This device was then used to measure sediment concentrations during monsoon runoff events at the USDA-ARS Walnut Gulch experimental watershed in southeast Arizona as an example application. Data were obtained using a 55 cm, three-prong, embedded time domain reflectometry probe and sediments in a range of size classes from the site under laboratory conditions. In the laboratory, the sensor's concentration output was calculated using a model and the empirical function describing pure water. Without sediment-specific calibration, laboratory validation indicated agreement with known concentrations within about 0.02 kg L super(-1) for sediment and water mixtures and within 0.2 kg L super(-1) when the probe was completely buried in 0 to 2.5 cm channel bed material. In the field application, the probe was installed in the base and center of a flume. Basal (0 to 2 cm depth) sediment concentrations were monitored during three flows with peak discharges of 5, 70, and 130 m super(3) s super(-1), representing small, intermediate, and large events. For the large and intermediate events, basal sediment concentrations rose from 0.4 to 1.2 kg L super(-1) to a plateau of 1.5 to 1.9 kg L super(-1) after the flow peak. The plateau extended through much of the tail of the hydrograph before falling to back to 0.4 to 1.2 kg L super(-1). The small event had a similar progression but lower overall concentrations of 0.2 to 0.8 kg L super(-1). These observations are consistent with a period of high sediment transport and channel erosion in the tail of monsoon runoff hydrographs. The dielectric method provides in-situ measurements in high-concentration environments where traditional methods fail.

A three-step sequential extraction procedure was utilised for the fractionation of Se in mine tailings and soils. The first extractant in order to evaluate the soluble and ligand exchangeable fraction of Se (0.1 mol/l K sub(2)HPO sub(4 )+ KH sub(2)PO sub(4) at pH 7.0) solubilized up to 15% of total Se content. The second step (0.1 mol/l K sub(2)S sub(2)O sub(8) at 90 degree C) which extracted Se associated or occluded with organic matter released 13 - 45% of total selenium. The decomposition of the residue (HNO sub(3) + H sub(2)SO sub(4 )1+1) was used to solubilize the remaining 35-88% of total Se as the final step. The recovery of the procedure was between 97 and 106%. Selenate predominated in natural river and lake waters about pH 7.0 (>95%) but in acid mine leakings up to 40% of selenite was found. In the plants (birch leaves, grass leaves and roots) collected from the area acidified by mine leakings no significant accumulation of selenium was observed. The correlation between total Se and S in the rocks from the mine gives an evidence of the common origin of these elements in the studied area.

We investigated whether the survival of the opportunistic pathogen Pseudomonas aeruginosa in the wheat rhizosphere would be affected by the presence of natural and constructed microbial communities of various diversity levels. Three levels of microbial community diversity were derived from wheat roots by a dilution/extinction approach. These wheat rhizosphere inocula, as well as a gnotobiotic microbial community consisting of seven culturable wheat rhizobacterial isolates, were introduced into the nutrient solution of hydroponically grown wheat plants on the day of planting. Phenotypic characterization of the culturable microbial communities on R2A medium, Shannon microbial diversity index, community-level physiological profiles, and terminal restriction fragment length polymorphisms were used to assess the varying microbial diversity levels. At day 7 the roots were invaded with P. aeruginosa and the number of P. aeruginosa colony forming units per root were measured at day 14. The average number of surviving P. aeruginosa cells was 3.52, 4.90, 7.18, 6.65 log sub(10) cfu/root in the high, medium, low, and gnotobiotic microbial community diversity level treatments, respectively. The invasibility of the rhizosphere communities by P. aeruginosa was inversely related to the level of diversity from the dilution extinction gradient. The gnotobiotic community did not confer protection against P. aeruginosa invasion. Although these data indicate that invasibility is inversely related to diversity, further study is needed to both reproduce these findings and define the specific mechanisms of the diversity effect.

The study was considered a severe test because it included a large volume of treated wood in a site with high annual rainfall. Soil and sediment samples were collected before construction and 0.5, 2, 5.5, 11, 24, and 60 months after construction. Increased concentrations of copper, chromium, and arsenic were detected in some soil and sediment samples. The environmental concentrations varied with time, proximity to the treated wood, and type of exposure. Concentrations of leached components in the soil developed slowly and were greatest at the 60-month sampling. Soil samples with elevated levels of copper and chromium were confined to directly under the dripline of the boardwalk, and arsenic appeared to be limited to within 0.3 m (1 ft.) of the structure. Concentrations of leached components in the sediments increased more quickly than those in the soil and reached maximum or near maximum levels within the first year. Elevated concentrations of copper, chromium, and arsenic were found in sediments as much as 3 m (10 ft.) from the boardwalk. Concentrations of these elements were also generally greater in sediment than in soil, suggesting that factors other than leaching, such as abrasion of treated wood fiber caused by foot traffic, may be contributing to environmental releases. In both soil and sediment samples, total copper and arsenic concentrations were consistently more elevated than chromium concentrations.

P reaching the reservoir is thought to emanate from runoff from the surrounding farms, mainly as a result of manure spread on these farms. Efforts to address the problem have involved implementation of BMPs on the watersheds; however, the effectiveness of these practices is not known. This study establishes a means of estimating BMP effectiveness, based on data available in the literature, and develops a tool that allows users to obtain BMP effectiveness estimates for their respective site soil and slope conditions. The tool offers stand-alone capabilities and has the potential to be linked to a GIS. An example is presented to illustrate tool application for effectiveness-based BMP selection, with a focus on a farm within the New York City watersheds.

A Comment AN - 1171870647; 17054868 AB - The Conservation Reserve Program (CRP) pays farmers about $2 billion per year to retire cropland under ten- to fifteen-year contracts. Recent research by Wu found that slippage-an unintended stimulus of new plantings-offsets some of CRP's environmental benefits. Wu does not account for the endogeneity of CRP enrollments. Furthermore, the data used by Wu cannot be used to estimate slippage arising from a price feedback effect. We replicate Wu's findings, demonstrate the possible presence of spurious correlation, and construct new estimates with corrections for endogeneity and other econometric problems. We find no convincing evidence of slippage.

Results reveal substantial scale economies that show no evidence of diminishing with plant size and that are much greater than those realized in cattle and hog slaughter. Findings suggest that consolidation is likely to continue, particularly if demand growth diminishes, and that controlling for plant product mix is critical to accurate cost estimates.

Merr.] is an important protein source in human diets and animal rations. Additionally, human consumption of soybean protein is reported to provide specific health benefits. Since methionine and cysteine contents limit the nutritional value of soybean, efforts involving both traditional breeding and genetic engineering have been employed in attempts to increase the presence of these essential amino acids. Traditional breeding has been primarily utilized to increase the total protein content but not to enhance the sulfur amino acid content of soybean. Although mutagenesis in conjunction with traditional breeding is a viable approach for enhancing the sulfur amino acid content of soybean, genetic engineering appears to be a more realistic approach. Introduction of methionine-rich heterologous proteins has resulted in a modest increase of this amino acid in soybean. Either elevating the expression of endogenous methionine-rich proteins or introducing synthetic proteins containing a high percentage of essential amino acids are other possible approaches that may increase the nutritional quality of the seed. Even though considerable progress has been made in enhancing the methionine content of soybean, several obstacles remain. A thorough understanding the sulfur assimilatory pathway in soybean is a prerequisite for improving the sulfur amino acid content. Expression of feedback-insensitive forms of serine acetyl transferase and O-acetylserine (thiol) lyase, two key enzymes in sulfur assimilatory pathway, could lead to an increase in the availability of sulfur amino acids. An adequate supply of sulfur amino acids in developing seeds may facilitate accumulation of sulfur-rich proteins to a level sufficient to meet the nutritional requirement of livestock and poultry.

The IS-like elements were cloned from phytoplasma strains AY1 and NJAY or PCR-amplified from 15 additional strains representing nine subgroups in the AY group using primers based on sequences of the putative transposases (Tpases). All IS-like elements contained sequences encoding similar Tpases of 321 amino acids (320 for strain CPh). Substantial amino acid sequence variability suggested multiple species of Tpases or IS-like elements exist in the AY phytoplasma group. These Tpases have an identical DDE motif that is most similar to the DDE consensus of Tpases in the IS3 family.

Previous studies focused on plot-to-field scale P loss and reductions from best management practices (BMP's), little information in intense agricultural catchments has been gathered on the dynamics influencing P beyond the edge of the field. This study was conducted to examine the phosphorus equilibrium between the water column and sediments in three tile fed drainage ditches in Northeast Indiana. Surface water and sediment samples were collected and analyzed for organic carbon (C), particle size and P from sites along three ditches with similar soils and land use at sites within each watershed draining approximately 300 and 1500ha on each ditch. Organic C, silt and clay fractions of the bottom sediments decreased with increasing drainage area. Soluble P concentrations were low in Ditch A, but increased with increasing drainage area (0.02-0.05mg PL super(-) super(1)). Overall, the P concentrations were higher in the Ditches B and C (0.06-0.09mg PL super(-) super(1)). Exchangeable P, P partitioning index and equilibrium P concentrations (EPC sub(o)) decreased with increasing drainage area by as much as 95, 93 and 100%, respectively, except in one catchment area with a confined animal feeding operation between sampling points, where ExP and EPC sub(o) increased by 4 and 116%, respectively. Aluminum sulfate and calcium carbonate treatment of ditch sediments reduced exchangeable P and sediment EPC sub(o) in this study. Results from this study indicated some watershed characteristics, as well as sediment physiochemical properties, affect ditch sediment and water P equilibrium and buffering capacity. Furthermore, this study demonstrated that managers could potentially use chemical treatment of the ditches to increase the temporary retention of P in ditches and maybe reducing sediment P availability.

13882666 AB - Several composite blends of poly(vinyl alcohol) (PVA) and lignocellulosic fibers were prepared and characterized. Cohesive and flexible cast films were obtained by blending lignocellulosic fibers derived from orange waste and PVA with or without cornstarch. Films were evaluated for their thermal stability, water permeability and biodegradation properties. Thermogravimetric analysis (TGA) indicated the suitability of formulations for melt processing, and for application as mulch films in fields at much higher temperatures. Composite films were permeable to water, but at the same time able to maintain consistency and composition upon drying. Chemical crosslinking of starch, fiber and PVA, all hydroxyl functionalized polymers, by hexamethoxymethylmelamine (HMMM) improved water resistance in films. Films generally biodegraded within 30 days in soil, achieving between 50-80% mineralization. Both starch and lignocellulosic fiber degraded much more rapidly than PVA. Interestingly, addition of fiber to formulations enhanced the PVA degradation.

AN - 69088634; 16438296 AB - The heat-induced reaction of amino groups of amino acids, peptides, and proteins with carbonyl groups of reducing sugars such as glucose results in the concurrent formation of so-called Maillard browning products and acrylamide. For this reason, reported studies of adverse biological effects of pure acrylamide may not always be directly relevant to acrylamide in processed food, which may contain Maillard and other biologically active products. These may either antagonize or potentiate the toxicity of acrylamide. To stimulate progress, this paper presents an overview of selected reported studies on the antiallergenic/allergenic, antibiotic, anticarcinogenic/carcinogenic antimutagenic/mutagenic, antioxidative/oxidative, clastogenic (chromosome-damaging), and cytotoxic activities of Maillard products, which may adversely or beneficially impact the toxicity of acrylamide. The evaluation of biological activities of Maillard products and of other biologically active food ingredients suggests that they could both enhance and/or ameliorate acrylamide toxicity, especially carcinogenicity, but less so neurological or reproductive manifestations. Future studies should be directed to differentiate the individual and combined toxicological relationships among acrylamide and the Maillard products, define individual and combined potencies, and develop means to prevent the formation of both acrylamide and the most toxic Maillard products. Such studies should lead to safer foods.

AN - 69061572; 16389972 AB - Soil is a source of primary inoculum for Aspergillus flavus and A. parasiticus, fungi that produce highly carcinogenic aflatoxins in peanuts. Aflatoxigenic fungi commonly invade peanut seeds during maturation, and the highest concentrations of aflatoxins are found in damaged seeds. A laboratory procedure was developed in which viable peanut seeds were wounded and inoculated with field soil containing natural populations of fungi, then incubated under different conditions of seed water activity and temperature. Densities of Aspergillus section Flavi in soil used for inoculating seeds were low relative to the total numbers of filamentous fungi (<1%). Aspergillus species from section Flavi present in soil included A. flavus morphotypes L and S strains, A. parasiticus, A. caelatus, A. tamarii and A. alliaceus. Wounding was required for high incidences of fungal colonization; viability of wounded seeds had little effect on colonization by Aspergillus species. Peanut seeds were colonized by section Flavi species as well as A. niger over broad ranges of water activity (0.82-0.98) and temperature (15-37 C), and the highest incidences of seed colonization occurred at water activities of 0.92-0.96 at 22-37 C. A. parasiticus colonized peanut seeds at lower temperatures than A. flavus, and cool soil temperatures relative to temperatures of aerial crop fruits might explain why A. parasiticus is found mostly in peanuts. Other fungi, dominated by the genera Penicillium, Fusarium and Clonostachys, colonized seeds primarily at water activities and temperatures suboptimal for section Flavi species and A. niger. Eupenicillium ochrosalmoneum frequently sporulated on the conidial heads of section Flavi species and showed specificity for these fungi. The inoculation of wounded viable peanut seeds with soil containing natural populations of fungi provides a model system for studying the infection process, the interactions among fungi and those factors important in aflatoxin formation.

AN - 68909321; 16366853 AB - Concerns regarding an apparent association between the use of antimicrobial feed additives (AFAs) in food animal production and a concomitant increase in antimicrobial drug resistance among zoonotic enteropathogens have provided the impetus to propose cessation of their use. While AFAs have been used in food animal production for nearly 50 years, the future use of AFAs will require an understanding of the effects of different classes of antimicrobials on the antimicrobial resistance of commensal flora. The present study examines the effect of three AFAs (apramycin, carbadox, and chlortetracycline) on the antimicrobial susceptibility of Escherichia coli in growing piglets and on animal performance. Three replicate trials were conducted using growing piglets fed standard diets with and without antimicrobial feed additives (AFAs). Fecal samples were cultured selectively for E. coli at regular intervals from all piglets from birth to market and antimicrobial susceptibility testing of E. coli isolates was performed using a replica-plate screening method and a broth microdilution method. While resistance to tetracycline in E. coli varied widely by sample, group, and trial, a significant increase in the percentage of resistant isolates was observed in piglets receiving AFAs when compared to controls (p < 0.0001). Resistance to apramycin increased in E. coli from piglets fed apramycin when compared to controls (p < 0.0001). However, upon removal of apramycin, resistance in E. coli declined to baseline levels by day 75. Piglets receiving AFAs demonstrated improved feed efficiency during phase 4 (p < 0.001), and higher average daily gains in phases 3 and 4 (p < 0.0001). This study suggests that antimicrobial resistance to AFAs in E. coli is drug-dependent and that some antimicrobials may be suitable for continued use in feeds during specified growth periods without concern for persistence of resistant E. coli populations.

AN - 68848580; 16323050 AB - The southern cattle tick, Boophilus microplus (Canestrini), has developed resistance to amitraz in several countries in recent years. A study was conducted at the USDA Cattle Fever Tick Research Laboratory in Texas to investigate the mode of inheritance of amitraz resistance with cross-mating experiments. The Muñoz strain, a laboratory reared acaricide-susceptible reference strain, was used as the susceptible parent and the Santa Luiza strain, originating in Brazil, was used as the resistant parent. A modified 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. Results of reciprocal crossing experiments suggested that amitraz resistance was inherited as an incomplete recessive trait. There was a strong maternal effect on larval progeny's susceptibility to amitraz in both the F1 and the subsequent generations. The values of the degree of dominance were estimated at -0.156 and -0.500 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 that of the F2 generations suggested that more than one gene was responsible for amitraz resistance in the Santa Luiza strain. Comparisons of biological parameters (engorged female weight, egg mass weight, and female-to-egg weight conversion efficiency index) indicated significant differences between different genotypes. The differences appeared to be heritable, but not related to amitraz resistance. Results from this study may have significant implications for the management of amitraz resistance.

Following exposure to 2.4% acetic acid for 7 min, S. enterica (serovars Mbandaka, Chester and Newport) cells were used to inoculate enrichment broths, phosphate-buffered saline (PBS), apple juice and fruit slices. Injured Salmonella cells resuscitated and regained the ability to form colonies on selective agar (Xylose-Lysine-Tergitol 4) if they were incubated in lactose broth (LB), universal pre-enrichment broth (UPB) or buffered peptone water (BPW), but not in tetrathionate broth, PBS or apple juice. The resuscitation occurred at a significantly (P > 0.05) faster rate in UPB than in LB or BPW. The resuscitation also occurred on the surfaces of fresh-cut cucumber at 20 degrees C, but not at 4 degrees C. Acid-injured Salmonella cells resuscitated in nonselective enrichment broths at different rates, but not in selective enrichment broth, apple juice, PBS or on fresh-cut apple. Pre-enrichment of food samples in UPB prior to selective enrichment is recommended.

AN - 68713296; 16238748 AB - To determine if thyroid function affects faecal shedding of Escherichia coli O157:H7. Eight yearling cattle (n = 4 per treatment group), previously identified as shedding E. coli O157:H7, received either 0 or 10 mg 6-N-propyl-2-thiouracil (PTU) kg(-1) BW day(-1) for 14 days to reduce serum concentrations of the thyroid hormones, T(3) and T(4). Animals were monitored daily for changes in faecal shedding of E. coli O157:H7 and E. coli (EC) for the 14-day treatment period and an additional 7 days post-treatment. Body weight was measured weekly and serum concentrations of T(3) and T(4) were determined every 3 days. No differences in faecal shedding of E. coli O157:H7 were observed during the 14-day treatment period. However, compared with control animals, a greater percentage of PTU-treated cattle ejected E. coli O157:H7 on day 16 (100 vs 25%) and 18 (75 vs 0%) of the post-treatment period. Serum T(3) was lower in PTU-treated cattle during the 14-day treatment period and greater on day 18 of the post-treatment period. Cattle with chemically altered thyroid hormones had similar shedding patterns of faecal E. coli O157:H7 and EC during the 14-day treatment period. However, faecal shedding of E. coli O157:H7 tended to be greater, and serum concentrations of T(3), were greater for PTU-treated cattle immediately following the termination of PTU treatment. Short-term chemical inhibition of thyroid hormones had minimal effects on faecal shedding of E. coli O157:H7 in naturally infected cattle. However, a hyperthyroid state as observed postdosing might play a role in the seasonal shedding of E. coli O157:H7 in cattle.

AN - 68711654; 16238734 AB - This study evaluated the relationship between Campylobacter susceptibility and enteric fluoroquinolone concentrations in chickens treated with different doses of enrofloxacin. All chickens were challenged with seven fluoroquinolone sensitive Campylobacter jejuni (6.6 x 10(6) CFU per bird) at 2 weeks posthatch. At 26 days of age chickens were treated with 0 (n = 29 birds), 25 mg ml(-1) enrofloxacin (Baytril, Bayer Corp., Shawnee Mission, KS, USA) for 3 days (n = 45 birds) or 50 mg ml(-1) enrofloxacin for 7 days (n = 65 birds) in the drinking water. The crop, upper ileum, lower ileum, ceca and colon contents were collected from both enrofloxacin treatment groups (n = 5 birds per day per treatment group) and nonmedicated controls. The minimum inhibitory concentration (MIC) of ciprofloxacin for Campylobacter increased for isolates from both treatment groups within the first day of dosing and the daily average ranged from 1.4 to 6.5 microg ml(-1) throughout the study. Although enteric fluoroquinolone concentrations were higher (P < 0.05) in birds dosed with 50 mg ml(-1)vs 25 mg ml(-1) enrofloxacin, there were no differences between the isolates collected from these groups for MIC values. These data indicate, for the doses used, differences in gut fluoroquinolone concentrations do not produce isolates of Campylobacter with differing susceptibility to ciprofloxacin. Using the manufacturers lowest, shortest duration dose vs the highest, longest duration dose of enrofloxacin did not change Campylobacter susceptibility to ciprofloxacin. However, ciprofloxacin MIC values for Campylobacter determined in this study were lower than previously reported.

AN - 68643808; 16197313 AB - Inadequate folate intake and aging are each strongly implicated as important risk factors for certain cancers. Since both folate depletion and aging are strongly associated with hyperhomocysteinemia, genomic DNA hypomethylation, and increased uracil misincorporation into DNA, it appears that each of them enhances carcinogenesis by inducing a derangement of one-carbon metabolism that supplies one-carbons to biological methylation reactions and nucleotide synthesis. Recent studies have demonstrated that inadequate dietary folate and aging may interact and synergistically disturb the normal homeostasis of one-carbon metabolism, thereby provoking subsequent biochemical and molecular aberrations, including alterations in critical gene expression related to carcinogenesis. These studies have further indicated that modest folate supplementation may reverse or partially ameliorate those adverse effects induced by folate depletion and aging.

AN - 68587160; 16162238 AB - This study compared the chemical, physical and bacterial composition of circulated and stagnant dairy wastewaters. Samples taken from circulated and stagnant wastewater lagoons, over a 1-year period, were analysed for 10 chemical (total N, NH3, NO3, NO2, Na, Ca, HCO3, Fe, P and K) and six physical (biological oxygen demand, chemical oxygen demand, dissolved solids, electrical conductivity, pH and sodium absorption ratio) parameters and were found to be similar. The 16S rDNA genes from the samples were amplified, cloned and BLAST analysed. In total, 996 stagnant and 1052 circulated wastewater derived sequences were obtained, comprising 294 and 362 operational taxonomic units (OTUs) from the circulated and stagnant wastewaters respectively. Coverage estimates of the OTUs identified were 72.1% for the stagnant, and 63.6% for the circulated wastewater libraries. The greatest difference between the two wastewaters was a c. sixfold greater number of sequences representative of the family Chromatiaceae in the circulated wastewater derived library and a c. fivefold greater number of sequences representative of the phylum Chloroflexi in the stagnant wastewater derived library. Circulation of dairy wastewater does not affect any of the chemical or physical parameters tested; however, circulation does alter the bacterial community structure. This study provides evidence that circulation of dairy wastewater promotes the growth of bacteria within the family Chromatiaceae and that stagnant systems promote the growth of the phylum Chloroflexi.

AN - 68581437; 16156707 AB - Swine can harbor Salmonella in their gastrointestinal tracts. It has been estimated that up to 48% of the U.S. swine herd may carry Salmonella. Housing sows in farrowing stalls has become controversial due to animal welfare-based criticisms. An alternative production system is to keep sows outdoors on pasture with access to individual farrowing huts. This study was designed to determine the effects of two production systems on indicator bacteria and Salmonella of sows housed indoors in farrowing stalls (n = 52) compared to sows housed outdoors (n = 52) in English style huts. Each farrowing radial contained one wallow, from which mud (n = 290) and water (n = 290) samples were collected weekly. All samples were analyzed for generic E. coli, coliforms and Salmonella. No differences (p > 0.05) were detected in Salmonella, generic E. coli and coliform populations between indoor farrowing stalls and outdoor farrowing huts. However, all 8 outdoor wallows contained Salmonella spp. at some point during the study (n = 49 Salmonella isolates). Salmonella genotypes persisted within some wallows for >5 months, and genetically indistinguishable Salmonella isolates were found in multiple wallows. Salmonella isolated from outdoor sow feces were genetically indistinguishable by PFGE from Salmonella isolated from wallows (n = 33) throughout the study, indicating that pathogenic bacteria were cycling between swine and their environment. In conclusion, the role of wallows in disseminating Salmonella within an outdoor swine herd appears to be significant.

AN - 68492374; 16108793 AB - To compare the biosynthetic gene cluster sequences of the main aflatoxin (AF)-producing Aspergillus species. Sequencing was on fosmid clones selected by homology to Aspergillus parasiticus sequence. Alignments revealed that gene order is conserved among AF gene clusters of Aspergillus nomius, A. parasiticus, two sclerotial morphotypes of Aspergillus flavus, and an unnamed Aspergillus sp. Phylogenetic relationships were established using the maximum likelihood method implemented in PAUP. Based on the Eurotiomycete/Sordariomycete divergence time, the A. flavus-type cluster has been maintained for at least 25 million years. Such conservation of the genes and gene order reflects strong selective constraints on rearrangement. Phylogenetic comparison of individual genes in the cluster indicated that ver-1, which has homology to a melanin biosynthesis gene, experienced selective forces distinct from the other pathway genes. Sequences upstream of the polyketide synthase-encoding gene vary among the species, but a four-gene sugar utilization cluster at the distal end is conserved, indicating a functional relationship between the two adjacent clusters. The high conservation of cluster components needed for AF production suggests there is an adaptive value for AFs in character-shaping niches important to those taxa. This is the first comparison of the complete nucleotide sequences of gene clusters harbouring the AF biosynthesis genes of the main AF-producing species.

AN - 68081883; 16047889 AB - Organic amendments are sometimes applied to agricultural soils to improve the physical, chemical, and microbiological properties of the soils. The organic fractions in these soil amendments also influence metal reaction, particularly the adsorption and desorption of metals, which, in turn, determine the bioavailability of the metals and hence their phytotoxicities. In this study, a Quincy fine sandy (mixed, mesic, Xeric Torripsamments) soil was treated with 0 to 160 g kg(-1) rates of either manure, sewage sludge (SS), or incinerated sewage sludge (ISS) and equilibrated in a greenhouse at near field capacity moisture content for 100 days. Following the incubation period, the soil was dried and adsorption of copper (Cu) was evaluated in a batch equilibration study at either 0, 100, 200, or 400 mg L(-1) Cu concentrations in a 0.01M CaCl2 solution. The desorption of adsorbed Cu was evaluated by three successive elutions in 0.01M CaCl2. Copper adsorption increased with an increase in manure rates. At the highest rate of manure addition (160 g kg(-1) soil), Cu adsorption was two-fold greater than that by the unamended soil at all rates of Cu additions. With increasing rates of Cu additions, the adsorption of Cu decreased from 99.4 to 77.6% of Cu applied to the 160 g kg(-1) manure amended soil. The desorption of Cu decreased with an increase in rate of manure amendment. Effects of sewage sludge amendments on Cu adsorption were somewhat similar to those as described for manure additions. Likewise, the desorption of Cu was the least at the high rate of SS addition (160 g kg(-1)), although at the lower rates there was not a clear indication of the rate effects. In contrast to the above two amendments, the ISS amendment had the least effect on Cu adsorption. At the highest rate of ISS amendment, the Cu adsorption was roughly 50% of that at the similar rate of either manure or SS amendments, across all Cu rates.

AN - 68059711; 16033506 AB - To evaluate PCR primers for the detection of pathogenic Escherichia coli in a real-time PCR assay and determine their utility in produce irrigation water testing. Three previously published PCR primer sets and one set designed for this study were tested for their ability to produce amplification products for several pathogenic E. coli serotypes from whole cells as template. Two of the previously published primer sets were chosen for real-time PCR detection limit determination. The coneaeA and PEH detection limit of E. coli O157:H7 was 10(0) and 10(1) CFU rxn(-1) in sterile water respectively. To detect E. coli O157:H7 in sprout irrigation water, the water required dilution due to PCR inhibitors. The detection limit of the coneaeA and PEH was 10(1) and between 10(2) and 10(3) CFU rxn(-1) in diluted sprout irrigation water respectively. The primer set coneaeA was able to produce an amplification product from each E. coli serotype, except O128:H7 and most sensitive for real-time PCR detection of pathogenic E. coli in diluted sprout irrigation water. The necessity of a dissociation analysis to distinguish positive samples from those with fluorescence of random dsDNA generation for real-time PCR in a complex background was established.

AN - 68031707; 16011437 AB - We report an agricultural fair-associated shiga-toxigenic Escherichia coli O157:H7 (STEC O157) outbreak that was unusual in that it affected both livestock exhibitors and visitors. Twenty-five human cases of STEC O157 infection were detected after the Fort Bend County Fair in Rosenberg, Texas, which ran from 9/26/03 to 10/04/03. Seven cases were culture-confirmed. There were four hemolytic uremic syndrome (HUS) cases, and one thrombotic thrombocytopenic purpura (TTP) case. Cases ranged in age from 18 months to 67 years. Twenty-two (88%) cases were female. Analysis of unmatched case-control data linked STEC O157 infection with visiting fair livestock exhibit areas and with multiple fair visits. All outbreak-related isolates were of a single STEC O157 subtype. Fair Ground environmental sampling and culture for STEC O157, conducted 46 days after the end of the Fair, yielded multiple STEC O157 isolates, including the outbreak subtype. Livestock exhibitors and fair visitors should follow guidelines to reduce the risk of transmission of STEC O157 at agricultural fairs. JF - Vector borne and zoonotic diseases (Larchmont, N.Y.)

AN - 67995053; 15992302 AB - Campylobacter jejuni remains the most frequently reported bacterial cause of human gastroenteritis in Nordic countries. The primary source of transmission to humans is suggested as mishandled raw poultry or consuming improperly prepared chicken. The focus of this report was to characterize the prevalence and cell numbers of the organism within the commercial Icelandic poultry industry. Commercial broiler flocks were sampled from May 2001 through 2003 in a total population study. At the slaughter plant, 40 randomly selected ceca were obtained from each flock, pooled into four samples containing 10 ceca each, and analyzed. Cell numbers and prevalence of Campylobacter spp. were estimated by direct plating of dilutions onto Campy-Cefex agar and incubating the plates at 42 degrees C under microaerobic atmosphere; colonies were confirmed as Campylobacter spp. by microscopy and latex agglutination to provide quantification of cell numbers per gm of cecal material. A total of 15.4% of the flocks carried the organism at at a maximum cell number of 8.1 x 10(7) cfu/g, having a mean raw count of colonized birds at 1.3 x 10(7) cfu/g (geometric mean of 1.5 x 10(6)). During the 3 years of sampling, the prevalence ranged from 17.6% to 17.3% to 12.7% for slaughter years 2001, 2002, and 2003, respectively. Isolation rates varied with numbers of catch lots (groups of birds taken for slaughter)/flock; with one catch lot/flock, the prevalence was 13.7%, with two 17.5%, and with three 33.3%. With increased flock size, isolation rates also increased; flocks of greater than 5,000 birds had a prevalence of 12.0% positive, 14.0% of flocks with 5,000-10,000 birds were positive, and 25.5% of flocks with more than 10,000 birds were positive for Campylobacter spp. Isolation rates varied with the processing lines: M was positive at 17.3%, B was positive at 10.1%, and G at 17.2%. Flocks were more frequently colonized in the warmer months, and younger birds were less frequently colonized than were older slaughtered birds. This study provides descriptive microbiology pertaining to Iceland broilers in a total population study.

AN - 67990310; 15991723 AB - Pyrolysis-gas chromatography-mass spectrometry (MS) was used to identify the major organic products produced by pyrolysis of three foundry sand resins: (i) Novolac and (ii) phenolic urethane (PU) (both phenol-formaldehyde based resins) and (iii) furan (furfuryl alcohol based resin). These resins are used in the metal casting industry as a "sand binder" for making cores (used to produce cavities in molds) and molds for nonferrous castings. During the casting process, the cores and molds are subjected to intense heat from the molten metal. As a result, the organic resins undergo thermal decomposition and produce a number of complex organic compounds. In this study, the organics were tentatively identified by MS after pyrolysis of the resins at 750 degrees C. The major thermal decomposition products from the Novolac, PU, and furan resins were derivatives of phenol, benzene, and furan, respectively. Compounds identified that are of potential environmental concern were benzene, toluene, phenol, o- and p-xylene, o- and m-cresol, and polycyclic aromatic hydrocarbons. Pyrolysis of the Novolac resin resulted in the generation of the most compounds of environmental concern. Because there is interest in beneficially using foundry molding sands in manufactured soils and other agricultural products, it is necessary that organic thermal decomposition products be identified to ensure environmental protection.

AN - 67863369; 15913016 AB - A major, often unrecognized variable regulating plant growth in semi-closed environment is air contaminant. The vapor of propylene glycol (PG), which was used as coolant in growth chambers, has been found to be toxic to corn (Zea mays L.) and soybean (Glycine max L.) plants. PG solution leaked from a valve packing system and volatilized to vapor, which was trapped in a semi-closed growth chamber. Symptoms of leaf edge chlorosis, later developing into necrosis, were observed on the third day of emergence or on the third day after moving healthy plants into the chamber. For young soybean plants, symptoms were slightly different from those observed in corn plants; the chlorosis symptoms were not uniformly distributed on all leaves. Some soybean leaves curled up and others had white spots. This problem was identified by using a portable photoionization detector to obtain instantaneous readings of total volatile organic compound concentrations inside the chambers.

AN - 67753143; 15839480 AB - Many mammals and birds roll on or rub themselves with millipedes that discharge benzoquinones. Chemicals transferred from millipedes onto the integument of anointing animals are thought to deter ectoparasites. We tested the lone star tick, Amblyomma americanum (L.), for responses to three widespread components of millipede defensive secretions, 1,4-benzoquinone; 2-methyl-1,4-benzoquinone (toluquinone); and 2-methoxy-3-methyl-1,4-benzoquinone (MMB). In toxicity tests, ticks were confined for 1 hr in filter-paper packets treated with serial dilutions of each of the benzoquinones or the commercial acaricide permethrin. Ticks were least affected by toluquinone, and most affected by permethrin. Of the benzoquinones, only MMB showed repellent activity. Behavioral assays were more sensitive than mortality for measuring the effects of the benzoquinones. Latencies for ticks to right themselves and to climb were greater with all compounds, even at the lowest concentrations, than with controls. Ticks exposed to low concentrations of benzoquinones appeared to recover over time, whereas those exposed to high concentrations exhibited behavioral abnormalities 1-3 mo later. Our results indicate that benzoquinones appropriated via anointing may reduce the tick loads of free-ranging animals, although key questions remain on the amounts of these compounds available to and effectively appropriated by anointing animals.

AN - 67734062; 15471532 AB - Hopperburn is a non-contagious disease of plants caused by the direct feeding damage of certain leafhoppers and planthoppers. Although long studied, especially with Empoasca spp. leafhoppers (Cicadellidae: Typhlocybinae), the mechanisms underlying hopperburn have only recently been elucidated. Hopperburn is caused by a dynamic interaction between complex insect feeding stimuli (termed hopperburn initiation) and complex plant responses (termed the hopperburn cascade). Herein we review the nature of the feeding stimuli in hopperburn initiation, especially for Empoasca spp., which we also compare with the planthopper Nilaparvata lugens. Contrary to previous reports, Empoasca hopperburn is not caused solely by toxic saliva. Instead, it is caused by a plant wound response triggered by a unique type of stylet movement, which is then exacerbated by saliva. Electrical penetration graph monitoring has revealed that all Empoasca spp. are cell rupture feeders, not sheath feeders, and that certain tactics of that feeding strategy are more damaging than others. Measuring the proportions of the most damaging feeding led to development of a resistance index, the Stylet Penetration Index, which can predict hopperburn severity in different plants or under different environmental conditions and can supplement or replace traditional, field-based resistance indices.

AN - 67734017; 15825686 AB - Atmospheric emission of the soil fumigant 1,3-dichloropropene (1,3-D) has been associated with the deterioration of air quality in certain fumigation areas. To minimize the environmental impacts of 1,3-D, feasible and cost-effective control strategies are in need of investigation. One approach to reduce emissions is to enhance the surface layer of a soil to degrade 1,3-D. A field study was conducted to determine the effectiveness of composted steer manure (SM) and composted chicken manure (CKM) to reduce 1,3-D emissions. SM or CKM were applied to the top 5-cm soil layer at a rate of 3.3 or 6.5 kg m(-2). An emulsified formulation of 1,3-D was applied through drip tape at 130.6 kg ha(-1) into raised beds. The drip tape was placed in the center of each bed (102 cm wide) and 15 cm below the surface. Passive flux chambers were used to measure the loss of 1,3-D for 170 h after fumigant application. Results indicated that the cumulative loss of 1,3-D was about 48% and 28% lower in SM- and CKM-amended beds, respectively, than in the unamended beds. Overall, both isomers of 1,3-D behaved similarly in all treatments. The cumulative loss of 1,3-D, however, was not significantly different between the two manure application rates for either SM or CKM. The results of this study demonstrate the feasibility of using composted animal manures to control 1,3-D emissions. JF - Journal of environmental science and health. Part.

AN - 67526413; 15777005 AB - The effectiveness of a single treatment with either ivermectin or moxidectin was determined by administering a single subcutaneous injection of each endectocide at 200 microg per kg body weight to cattle infested with all parasitic developmental stages (adults, nymphs, and larvae) of Boophilus microplus (Canestrini). The percentage reduction in the number of females that reached repletion following treatment (outright kill) was 94.8 and 91.1% for ivermectin and moxidectin, respectively. In addition, the reproductive capacity of the females that did survive to repletion was reduced by > 99%, regardless of the endectocide. Based on these two factors, the therapeutic level of control obtained against ticks on the cattle at the time of treatment was 99.0 and 99.1% for ivermectin and moxidectin, respectively. Engorged females recovered from either group of treated cattle weighed approximately 3-times less than untreated females, and the egg masses produced by treated females weighed approximately 5-8-times less than egg masses produced by untreated females. Partitioning of data into three separate 7-d post-treatment intervals allowed for an estimation of the efficacy of each endectocide against each individual parasitic development stage (adult, nymph, and larva). Results indicated that both endectocides were > or =99.7% effective against ticks that were in either the adult or nymphal stage at the time of treatment. However, the level of control against ticks in the larval stage of development at treatment was significantly lower at 97.9 and 98.4% for ivermectin and moxidectin, respectively. Analysis of the persistent (residual) activity of the two endectocides indicated that neither material provided total protection against larval re-infestation for even 1-wk following treatment. Against larvae infested 1-4 wk following treatment, the level of control with moxidectin ranged from 92.4% (1 wk) to 19.5% (4 wk). These control levels were higher at each weekly interval than for ivermectin, which ranged from 82.4% (1 wk) to 0.0% (4 wk). The potential for the use of these injectable endectocide formulations in the US Boophilus Eradication Program is discussed.

AN - 67399849; 15690802 AB - Potential biological control inoculants, Pseudomonas fluorescens 2-79 and microbial communities derived from market sprouts or laboratory-grown alfalfa sprouts, were introduced into alfalfa seeds with and without a Salmonella inoculum. We examined their ability to inhibit the growth of this foodborne pathogen and assess the relative effects of the inoculants on the alfalfa microbial community structure and function. Alfalfa seeds contaminated with a Salmonella cocktail were soaked for 2 h in bacterial suspensions from each inoculant tested. Inoculated alfalfa seeds were grown for 7 days and sampled during days 1, 3, and 7. At each sampling, alfalfa sprouts were sonicated for 7 min to recover microflora from the surface, and the resulting suspensions were diluted and plated on selective and nonselective media. Total bacterial counts were obtained using acridine orange staining, and the percentage culturability was calculated. Phenotypic potential of sprout-associated microbial communities inoculated with biocontrol treatments was assessed using community-level physiological profiles based on patterns of use of 95 separate carbon sources in Biolog plates. Community-level physiological profiles were also determined using oxygen-sensitive fluorophore in BD microtiter plates to examine functional patterns in these communities. No significant differences in total and mesophilic aerobe microbial cell density or microbial richness resulting from the introduction of inoculants on alfalfa seeds with and without Salmonella were observed. P. fluorescens 2-79 exhibited the greatest reduction in the growth of Salmonella early during alfalfa growth (4.22 log at day 1), while the market sprout inoculum had the reverse effect, resulting in a maximum log reduction (5.48) of Salmonella on day 7. Community-level physiological profiles analyses revealed that market sprout communities peaked higher and faster compared with the other inoculants tested. These results suggest that different modes of actions of single versus microbial consortia biocontrol treatments may be involved.

AN - 67378864; 15378342 AB - Global emissions of atmospheric CO(2) and tropospheric O(3) are rising and expected to impact large areas of the Earth's forests. While CO(2) stimulates net primary production, O(3) reduces photosynthesis, altering plant C allocation and reducing ecosystem C storage. The effects of multiple air pollutants can alter belowground C allocation, leading to changes in the partial pressure of CO(2) (pCO(2)) in the soil , chemistry of dissolved inorganic carbonate (DIC) and the rate of mineral weathering. As this system represents a linkage between the long- and short-term C cycles and sequestration of atmospheric CO(2), changes in atmospheric chemistry that affect net primary production may alter the fate of C in these ecosystems. To date, little is known about the combined effects of elevated CO(2) and O(3) on the inorganic C cycle in forest systems. Free air CO(2) and O(3) enrichment (FACE) technology was used at the Aspen FACE project in Rhinelander, Wisconsin to understand how elevated atmospheric CO(2) and O(3) interact to alter pCO(2) and DIC concentrations in the soil. Ambient and elevated CO(2) levels were 360+/-16 and 542+/-81 microl l(-1), respectively; ambient and elevated O(3) levels were 33+/-14 and 49+/-24 nl l(-1), respectively. Measured concentrations of soil CO(2) and calculated concentrations of DIC increased over the growing season by 14 and 22%, respectively, under elevated atmospheric CO(2) and were unaffected by elevated tropospheric O(3). The increased concentration of DIC altered inorganic carbonate chemistry by increasing system total alkalinity by 210%, likely due to enhanced chemical weathering. The study also demonstrated the close coupling between the seasonal delta(13)C of soil pCO(2) and DIC, as a mixing model showed that new atmospheric CO(2) accounted for approximately 90% of the C leaving the system as DIC. This study illustrates the potential of using stable isotopic techniques and FACE technology to examine long- and short-term ecosystem C sequestration.

AN - 67357940; 15647560 AB - Land application of biosolids is a beneficial-use practice whose ecological effects depend in part on hydrological effects. Biosolids were surface-applied to square 0.5-m2 plots at four rates (0, 7, 34, and 90 dry Mg ha(-1)) on each of three soil-cover combinations in Chihuahuan Desert grassland and shrubland. Infiltration and erosion were measured during two seasons for three biosolids post-application ages. Infiltration was measured during eight periods of a 30-min simulated rain. Biosolids application affected infiltration rate, cumulative infiltration, and erosion. Infiltration increased with increasing biosolids application rate. Application of biosolids at 90 dry Mg ha(-1) increased steady-state infiltration rate by 1.9 to 7.9 cm h(-1). Most of the measured differences in runoff among biosolids application rates were too large to be the result of interception losses and/or increased hydraulic gradient due to increased roughness. Soil erosion was reduced by the application of biosolids; however, the extent of reduction in erosion depended on the initial erodibility of the site. Typically, the greatest marginal reductions in erosion were achieved at the lower biosolids application rates (7 and 34 dry Mg ha(-1)); the difference in erosion between 34 and 90 dry Mg ha(-1) biosolids application rates was not significant. Surface application of biosolids has important hydrological consequences on runoff and soil erosion in desert grasslands that depend on the rate of biosolids applied, and the site and biosolids characteristics.

AN - 67356842; 15647558 AB - Subsurface soil water dynamics can influence crop growth and the fate of surface-applied fertilizers and pesticides. Recently, a method was proposed using only ground-penetrating radar (GPR) and digital elevation maps (DEMs) to identify locations where subsurface water converged into discrete pathways. For this study, the GPR protocol for identifying horizontal subsurface flow pathways was extended to a 3.2-ha field, uncertainty is discussed, and soil moisture and yield patterns are presented as confirming evidence of the extent of the subsurface flow pathways. Observed soil water contents supported the existence of discrete preferential funnel flow processes occurring near the GPR-identified preferential flow pathways. Soil moisture also played a critical role in the formation of corn (Zea mays L.) grain yield patterns with yield spatial patterns being similar for mild and severe drought conditions. A buffer zone protocol was introduced that allowed the impact of subsurface flow pathways on corn grain yield to be quantified. Results indicate that when a GPR-identified subsurface clay layer was within 2 m of the soil surface, there was a beneficial impact on yield during a drought year. Furthermore, the buffer zone analysis demonstrated that corn grain yields decreased as the horizontal distance from the GPR-identified subsurface flow pathways increased during a drought year. Averaged real-time soil moisture contents at 0.1 m also decreased with increasing distance from the GPR-identified flow pathways. This research suggests that subsurface flow pathways exist and influence soil moisture and corn grain yield patterns.

Revenue insurance and chemical input use. AN - 67332765; 15572077 AB - Using farm level data we evaluate the input use and environmental effects of revenue insurance. A priori, the moral hazard effect on input use is indeterminate. This paper empirically assesses the input use impact of the increasingly popular, and federally subsidized, risk management instrument of revenue insurance and the extent to which its effects on input use may differ from those of the older yield based instruments. We conclude that among winter wheat farmers, those who purchase revenue insurance tend to spend less on fertilizers but do not appreciably alter pesticide expenditures. Thus, any improved environmental outcomes due to crop insurance are likely due to reduced fertilizer not pesticide use. When the environmental indicators included indicated a potential environmental fragility (i.e. high erosion, pesticide leaching or pesticide runoff potential), the input use equation suggested that fertilizer expenditures decreased. Revenue insurance undoubtedly further reduces fertilizer applications on these fields as well, but the marginal environmental benefit of revenue insurance is lessened because the reduction, where it matters most, accrues on land on which fertilizer use has already been curtailed to some degree.

AN - 67329271; 15593076 AB - Titers of two systemic neonicotinoid insecticides in citrus trees were measured in conjunction with conventional evaluations of their impact on glassy-winged sharpshooter (Homalodisca coagulata (Say); GWSS) populations. Xylem fluid samples were collected at regular intervals and from multiple locations within field-grown citrus trees to determine imidacloprid and thiamethoxam concentrations using commercial ELISA kits. Uptake profiles varied considerably with peak mean titers of imidacloprid occurring 6-8 weeks after application compared with 2 weeks for thiamethoxam. The persistence of each compound also varied as near-peak levels of imidacloprid were sustained for another 6-10 weeks before gradually declining. In contrast, thiamethoxam titers declined more rapidly after the initial peak, possibly reflecting an application rate only one-quarter of that used for imidacloprid. Within-tree distributions were more similar for the two compounds, with no significant effect due to height of the sample (upper or lower half) or to the quadrant location within the tree, with the exception of one quadrant in the thiamethoxam-treated trees. Substantial reductions in GWSS nymphs and adults were observed in imidacloprid-treated trees during the 2001 trial and were sustained for 4-5 months after treatment. Treatment effects on nymphs were not as well pronounced in the 2002 trial, when overall GWSS infestations were much reduced from the previous year. However, consistently lower adult infestations were still observed in 2002 for both treatments compared with untreated trees. Information on the spatial and temporal profiles in citrus trees was obtained for both compounds to complement field impact data and improve understanding of their pest management potential.

AN - 57652153; 409814 AB - Illiteracy is envisaged to be a major 'obstruction' on the road to Information Superhighway in Tanzania. Records indicate that over 90 percent literacy levels recorded in 1970s and 1980s for different reasons have dropped to only 78 percent. This paper highlights some of the factors causing high level of illiteracy rate and problems encountered by the information-starved people in their quest for knowledge and self-development as reviewed from different sources. It shows that Tanzanians are disadvantaged when it comes to accessing information and it also shows that commitment on the part of Governments, Non-Government organizations, libraries and other information professionals in this country can greatly help to eradicate illiteracy.

Flow forecasts are made by the Natural Resources Conservation Service using statistical models that use current snow and precipitation data collected at nearby monitoring sites as input. The forecasts for five upper Klamath Basin sites (Williamson River, Sprague River, Upper Klamath Lake, Gerber Reservoir, and Clear Lake Reservoir) are made at the beginning of each month from January through June. In 2003, the U.S. Geological Survey, the Natural Resources Conservation Service, and the Bureau of Reclamation began a collaborative study to reduce uncertainty and error in seasonal flow forecasting in the upper Klamath Basin. The main objectives included (1) evaluating nonregression statistical modeling approaches, such as artificial neural networks, for their efficacy in reducing model error, (2) finding and evaluating potential model variables that better described long-term climate-trend conditions, and (3) analyzing the efficacy of upper Klamath Basin snow-water equivalent and precipitation data in forecast models. The modeling approaches evaluated included principal components regression, nonautoregressive artificial neural networks, and autoregressive artificial neural networks. For the Upper Klamath Lake forecast site, the nonautoregressive artificial neural network models had lower error than the other models for the January, February, and March forecasts. However,the principal components regression model performed better for the April forecast. Both models performed roughly the same for the May and June forecasts. For the Sprague River forecast site, the nonautoregressive artificial neural network models performed far better than the other models for the January, February, March, and June forecasts. However, the principal components regression models performed better for the April and May forecasts. For the Williamson River and Gerber Reservoir forecast sites, the principal components regression models generally, but not always, performed better than the other models. For the Clear Lake Reservoir forecast site, the nonautoregressive artificial neural network models performed far better than the other models for the months of January, February, and March. However, the Clear Lake Reservoir autoregressive artificial neural network model performed better than the other models for the month of April. For the Williamson River, Upper Klamath Lake, and Gerber Reservoir forecast models, the inclusion of new long-term climate-trend variables reduced model error in many, but not all, instances. The relationships between the upper Klamath Basin snow-water equivalent, precipitation, and flow data were analyzed to determine the ability and the extent to which currentsnow-water equivalent and precipitation conditions can be used to forecast future flow conditions. The analyses were made by decomposing the flow time series into annual periodic, long-term climatic, and chaotic components, and then lag correlating the snow-water equivalent and precipitation time series with the chaotic component time series. After 120 days (approximately 4 months), all of the snow-water equivalent and precipitation correlation coefficients were less than 0.4.

Rather than resulting in uniform environmental values across the globe, we argue that distinct environmentalisms are socially constructed in different places through the complex interactions between the global environmental values and locally unique historical, political, and environmental factors. We analyze forest-related mental and cultural models-including both beliefs and values-using text analysis of transcripts and field notes from 67 qualitative interviews in five villages adjacent to La Amistad International Park in Costa Rica. We find that global environmental discourse has played a key role in framing the way rural people think and talk about forests. Conservation-oriented discourse has largely replaced earlier frontier views of forests as resources to be exploited and converted to agricultural lands. We find that the new forest beliefs and values are genuine, but also that they are sometimes superficial and lack motivating force. Local people are exposed to influential environmental discourses that see forests as something to be protected for heritage values and as a source of national development through ecotourism and bioprospecting, which often place forest conservation in opposition to their livelihood needs. This conflict has produced mediating discourses that acknowledge forest conservation as good while creating a legitimate place for rural landowners and their livelihood needs in the forested landscape. The result is unique local forest beliefs and values that are different from both earlier local beliefs and global and national environmental discourses.

The BCS was composed of 40% glycerol, 34% hexane-solubles (made up of 92% FA soaps/FAME and 6% MAG/DAG), and 26% water. Batch culture fermentations of the yeast Candida bombicola on pure glycerol resulted in low-level synthesis of SL (~ g/L). HPLC associated with atmospheric pressure CI-MS (LC/APCI-MS) revealed that the SL derived from pure glycerol had 99% of the FA side chains linked to the 4'' hydroxyl group of the sophorose sugar, resulting in a lactonic structure. In contrast, the use of the BCS as feedstock increased the SL yield to 60 g/L and the open-chain form to 75% including both oleic acid and linoleic acid (along with their methyl esters) as the dominant species comprising the side chains. By favoring the open-chain structure, the SL molecules (particularly the FA side chain) can be chemically modified without the need to open a lactone ring first. The ability to use the BCS as a feedstock for SL synthesis will provide an outlet for this residual material, thus helping to stimulate growth in the biodiesel market and the use of agricultural fats and oils from which the biodiesel was synthesized.

Pers.] hay to manage manure nutrients may differ from production of hay intended for livestock consumption. The objective of this study was to determine the relationships between maturity and yield, nutrient concentration, and nutrient uptake in bermudagrass fertilized with swine effluent. Primary spring and summer growth of 'Coastal' hybrid and common bermudagrass was harvested every 7 d to 63 d maturity. Effluent applied to Brooksville silty clay loam (fine, smectitic, thermic Aquic Hapludert) during each harvest period contained 140 kg nitrogen (N), 240 kg potassium (K), and 25 kg phosphorus (P) ha- 1 (mean of 2 years). Coastal and common bermudagrass had similar trends for yield, nutrient concentration, and nutrient uptake. Dry-matter production followed a linear trend in the spring (maximum of 1.11kg m- 2 after 63 d) and a quadratic trend in the summer (maximum of 0.96 kg m- 2 after 56 d). Herbage N concentration declined from 33 to 17 g kg- 1 during the spring and summer harvest period, while P concentration declined from 3.8 to 2.4 g kg- 1. Maximum K concentration (26 g kg- 1) occurred at 28 d of growth. Nitrogen, P, and K uptake exhibited a quadratic response to increasing maturity during the spring and summer harvest periods, but maximum uptake was greater in the spring than in the summer. These results suggest that the spring harvest period is the best time to maximize nutrient uptake by delaying bermudagrass harvest to more mature stages.

A 2 t 7 factorial design with three replications was used to test the effects of water ionic composition and salinity, respectively, on emergence, survival, and mineral accumulation of the salt-tolerant cut flower Limonium perezii (Stapf) F. T. Hubb cv. 'Blue Seas.' Seeds (n = 100) were sown in each of 42 presalinized greenhouse sand tanks. Irrigation water composition represented saline drainage waters typically present in either the San Joaquin Valley (SJV) or the Imperial/Coachella Valleys (ICV) of California. Electrical conductivity levels of the treatment waters were 2.5 (control), 6, 8, 10, 12, 16, and 20 dS m- 1, respectively. Seedling emergence was monitored daily and leaf mineral concentrations (total sulfur (S), total phosphorus (P), Ca2 +, Mg2 +, Na+, K+, and Cl-) were determined three months after planting. A two-way ANOVA revealed that salinity had a significant effect on seedling emergence (F = 27.56; P < 0.01). Cumulative emergence showed a marked decrease above 12 dS m- 1 for both water treatments and tended to be greater from 6-10 dS m- 1 than at 2.5 dS m- 1. A significant interaction of salinity and water composition was found for survival (F = 2.90; P < 0.05). Survival approximated 90% in ICV and SJV treatments up to 8 and 10 dS m- 1, respectively, yet continued to decrease below 70% in both water treatments at 12 dS m- 1 and higher. Differences in leaf-mineral concentrations between ICV and SJV water composition can be attributed to differences in composition of irrigation waters. As salinity increased, leaf Ca2 +, K+, and total P decreased, whereas Mg2 +, Na2 +, Cl-, and total S increased. Stem length showed a marked decrease above 2.5 and 6 dS m- 1 under ICV and SJV treatments, respectively, with SJV waters producing ~ 30% more marketable flowers at salinities up to 6 dS m- 1. Thus, Limonium perezii may be produced commercially with moderately saline wastewaters.

The older planting had a fescue (Festuca arundinaceae Schreb.) ground cover that is grazed by cattle. In the young plantation, weeds were mowed and sprayed with herbicides once annually in the spring. Litter was applied at rates of 6.72 Mg ha- 1 and 13.44 Mg ha- 1for one year in the spring in the young plantation and at 8.96 Mg ha- 1 for two years in the spring and once in late summer in the older plantation. Height growth and leaf nitrogen (N) concentrations were improved during the summer following litter applications in the young plantation, but neither diameter growth nor nut production increased in the older plantation. Second-year height growth treatment differences for the young plantation were not significant. The number of nuts increased in the second year, but differences between treatments were not significant.

In this paper we use data from 19 of those sites to characterize patterns and rates of coarse sediment transport for a range of channel types and sizes, including step-pool, plane-bed, pool-riffle, and near-braided channels. This effort builds upon previous work where we applied a piecewise regression model to (1) relate flow to rates of bedload transport and (2) define phases of transport in coarse-grained channels. Earlier, the model was tested using bedload data from eight sites on the Fraser Experimental Forest near Fraser, Colorado. The analysis showed good application to those data and to data from four supplementary channels to which the procedure was applied. The earlier results were, however, derived from data collected at sites that, for the most part, have quite similar geology and runoff regimes. In this paper we evaluate further the application of piecewise regression to data from channels with a wider range of geomorphic conditions. The results corroborate with those from the earlier work in that there is a relatively narrow range of discharges at which a substantial change in the nature of bedload transport occurs. The transition from primarily low rates of sand transport (phase I) to higher rates of sand and coarse gravel transport (phase II) occurs, on average, at about 80 per cent of the bankfull (1*5-year return interval) discharge. A comparison of grain sizes moved during the two phases showed that coarse gravel is rarely trapped in the samplers during phase I transport. Moreover, the movement and capture of the D sub(16) to D sub(25) grain size of the bed surface seems to correspond with the onset of phase II transport, particularly in systems with largely static channel surfaces. However, while there were many similarities in observed patterns of bedload transport at the 19 studied sites, each had its own "bedload signal" in that the rate and size of materials transported largely reflected the nature of flow and sediment particular to that system.

Growth of the SPB mutualistic fungus Entomocorticium sp. A on high melanin medium was less than half of the growth on control medium. Growth of O. ranaculosum was not significantly affected by the addition of melanin to malt extract agar. Four species of biological control (of bluestain) fungi showed the ability to decolorize melanistic O. minus cultures to various extents.

Due to considerable conservation in genome organization, these viruses contain easily identifiable intergenic regions that have been found to contain multiple DNA sequence elements important to viral replication and gene regulation. As a first step in a broad screen of geminivirus and nanovirus intergenic sequences for DNA segments important in controlling viral gene expression, we have 'mined' a large set of viral intergenic regions for transcriptional enhancers. Viral sequences that are found to act as enhancers of transcription in plants are likely to contribute to viral gene activity during infection. Results DNA sequences from the intergenic regions of 29 geminiviruses or nanoviruses were scanned for repeated sequence elements to be tested for transcription enhancing activity. 105 elements were identified and placed immediately upstream from a minimal plant-functional promoter fused to an intron-containing luciferase reporter gene. Transient luciferase activity was measured within Agrobacteria-infused Nicotiana tobacum leaf tissue. Of the 105 elements tested, 14 were found to reproducibly elevate reporter gene activity (>25% increase over that from the minimal promoter-reporter construct, p < 0.05), while 91 elements failed to increase luciferase activity. A previously described "conserved late element" (CLE) was identified within tested repeats from 5 different viral species was found to have intrinsic enhancer activity in the absence of viral gene products. The remaining 9 active elements have not been previously demonstrated to act as functional promoter components. Conclusion Biological significance for the active DNA elements identified is supported by repeated isolation of a previously defined viral element (CLE), and the finding that two of three viral enhancer elements examined were markedly enriched within both geminivirus sequences and within Arabidopsis promoter regions. These data provide a useful starting point for virologists interested in undertaking more detailed analysis of geminiviral promoter function.

The dry sample material was moistened by distilled water and after 5 days of incubation the amoebae were identified by direct examination. Identification of amoebae was performed on the base of morphological characters of the active stages. Relatively high diversity of 32 taxa of naked amoebae was recorded. The diversity at the sites varied from 17 to 23 taxa. The highest richness appeared in the family Thecamoebaidae (9 species), however some other families -Hartmannellidae, Vannellidae and Paramoebidae were significantly represented as well. The observed community of species of naked amoebae in mosses indicate considerable similarity to freshwater communities.

In California, it has invaded riparian zones, where it acts as a transformer species. Because plant growth and leaf quality influence the effectiveness of management techniques, we sought to determine if these characters varied temporally and spatially in a northern California population of A. donax. Tissue C and N content and C:N ratio varied during the growing season. Leaf N was higher in spring and in plants that were closer to a stream. It was significantly negatively related to the clump's distance from the stream but not related to its elevation relative to the stream. Plants near the stream produced taller stems with more leaves per stem than those more distant from the stream. RGR differed across time and space. It was highest in spring prior to the appearance of flowers on a few stems that were >1 year old within the clumps. Decline in RGR as the growing season progressed coincided with the appearance of branches and flowers on stems 1 year old). This implies that the decrease in stem growth reflected changes in nutrient availability within the entire A. donax clump and not just in the growing stems (<1 year old). These findings have implications for timing of management techniques.

Herein, we demonstrate that heterophils constitutively express TLR1/6/10, TLR2 type 1, TLR2 type 2, TLR3, TLR4, TLR5, and TLR7 mRNA. Furthermore, TLR agonists, including flagellin (from Salmonella typhimurium, FGN), peptidoglycan (from Staphylococcus aureus, PGN), ultra-pure lipopolysaccharide (from Salmonella minnesota, LPS), the synthetic double stranded RNA analog [poly(I:C)], and the guanosine analog, loxoribine (LOX) directly induced both an oxidative burst and a degranulation response. Interestingly, the synthetic bacterial lipoprotein Pam3CSK4 (palmitoyl-3-cysteine-serine-lysine-4, PAM) induced degranulation, but no oxidative burst. The bacterial TLR agonists (PAM, PGN, LPS, and FGN) all induced an up-regulation of expression of mRNA of the pro-inflammatory cytokines IL-1 beta , IL-6, and IL-8; whereas both poly(I:C) and LOX induced a down-regulation of these cytokine mRNAs. Stimulation of heterophils with each specific TLR agonist led to a differential increase in the phosphorylation of both p38 mitogen-activated protein kinase (MAPK) and extracellular signal-regulated kinase 1/2 (ERK 1/2) activation, but not the phosphorylation of c-Jun NH sub(2)-terminal kinase (JNK). The broad TLR expression profile in heterophils reflects their principal role as first line effector cells in avian host defense against bacterial, viral, fungal, and parasitic infections. The results demonstrate the differential involvement of TLR-induced signals in the stimulation of transduction pathways that regulate the oxygen-dependent and-independent antimicrobial defense mechanisms of avian heterophils.

The many herb and shrub species initially found in post-agricultural areas of this site declined or disappeared as the forest canopy closed. Tsuga canadensis ([L.] Carriere) increased in importance in the forest canopy until the introduction of the hemlock woolly adelgid (Adelges tsugae Annand). Shade-intolerant understory species are now increasing in abundance as the death of large T. canadensis opens gaps in the canopy. Mantel path analysis, a multivariate technique that allows examination of indirect and direct relationships among variables, was used to quantify the complex network of relationships among environment, land use history and plant community composition. Overall environmental variability was uncorrelated with vegetation, except within the shrub stratum. Slope and drainage were the most important individual environmental factors measured. Land use history was strongly correlated with all four strata, and the strength of this relationship decreased over time. The composition of the tree seedling stratum was highly variable through time; other strata showed more self- similarity between sample dates. Land use history appears to impact the vegetation so strongly as to conceal any effects of environmental variation on this site.

The sites have been covered by 40 to 100 year old oak-hornbeam forests. They are situated at the altitude of 240-350 m a.s.l. The samples have recorded the occurrence of Cryptops anomalans, Henia illyrica, Clinopodes flavidus, Geophilus flavus, Strigamia acuminata, S. transsilvanica, Schendyla nemorensis, Lithobius agilis, L. borealis, L. dentatus, L. erythrocephalus, L. forficatus, L. lapidicola, L. latro, L. lucifugus, L. melanops, L. mutabilis, L. muticus, L. pelidnus, L. piceus, L. aeruginosus, L. austriacus, L. crassipes and L. microps. The highest species richness refers to the site of Losonsky haj grove, the lowest diversity was recorded in Vinosady. The species diversity index (H') and equitability (e) reached their highest value in the community in Losonsky haj grove. Strigamia acuminata had the abundance (12.53 ind.m super(-2)) at the site of Nahac-Katarinka 2. The most abundant taxa have included Schendyla nemorensis (at Nahac-Katarinka 1-10.16 ind.m super(-2), Horny haj grove -9.6 ind.m super(-2)) and Lithobius austriacus (at the site of Nahac-Kukovacnik -8.45 ind.m super(-2)). Schendyla nemorensis and Lithobius muticus may be classified as eudominant species at all the study sites, their dominance was in average 40%. In all the dendrograms of cluster analyses the community at the site of Vinosady is separated from the other ones on the highest level of dissimilarity. The reason lies in the lowest number of determined species, a unique portion of Cryptops anomalans, absence of Strigamia acuminata and the lowest number of obtained specimens per 4 years. As for the species identity the centipede communities at the sites Losonsky haj grove and Nahac-Katarinka 1 may be classified as the most similar on the 87% level of similarity. The communities at Fugelka and Horny haj grove are close to each other (92% similarity) from the quantitative-qualitative point of view. Most of the recorded species occured throughout the year. Strigamia acuminata and Lithobius muticus were recorded continuously from March to November at most of the study sites. Schendyla nemorensis, present at all the sites, was often excluded from the species richness in the summertime samples. The typical centipede community in the oak-hornbeam forests of the Mate Karpaty Mts consists of the species: Schendyla nemorensis, Strigamia acuminata, Lithobius agilis, L. borealis, L. lapidicola, L. mutabilis, L. muticus, L. austriacus; in more southern drier parts of the Male Karpaty Mts Henia illyrica as well.

The mite communities in the study site Losonec-lom quarry regularly impacted by limestone dust from the nearby quarry show greater fluctuations in species richness and abundance of mites during the year. In the study site Losonsky haj grove Nature Reserve there are evident influence of more stable microclimatic conditions in the forest. The comparison of mite communities in consecutive years through hierarchical clustering suggests, that the temperature and air humidity can have stronger influence to mesostigmatid mite assemblages than the type of soil, pH and vegetation. From the faunistical point of view, Pergamasus canestrinii was recorded for the first time in Slovakia.

The investigation was performed on 10 study plots (forest stands of the age from 40 to 100 years) in the Mate Karpaty Mts and Trnavska pahorkatina hills, SW Slovakia. Each site was affected, to some extent by human activities of which forest fragmentation and pollution with calcareous dust were the most important. The soil macrofauna was collected by sifting the litter, surface layer of soil and remnants of twigs. Altogether 4,090 individuals of weevils classified into 78 species, 43 genera and 4 families were recorded. The number of species found at the particular sites ranged from 22 to 31 species. The mean abundance of weevils varied from 2.09 to 49.71 ind.m super(-2). Geophilous species Ceutorhynchus pallidactylus, geobionts Acalles fallax, Barypeithes chevrolati, Barypeithes mollicomus, Brachysomus hirtus, Trachodes hispidus and geoxenes Ceutorhynchus obstrictus and Sitona macularius predominated in the material from the oak-hornbeam forest epigeon. The canopy architecture and content of exchange bases in the leaf litter from amongst 13 gradient and 2 categorial variables analysed had direct and significant influence on the structure of epigeic weevil assemblages. The forest fragmentation caused increase the abundance of herbicolous, euryhygric and ubiquitous species in the epigeon of island woods. The weevil community was less abundant and unstable in the forest site polluted with calcareous dust.

The studied forest ecosystems, 40-100 years of age, are situated in the orographic units of the Male Karpaty Mts. and Trnavska pahorkatina hills and may be classified into 3 vegetation types: Carpinion betuli, Quercion confertae-cerris and Quercion pubescentis-petraeae. In total we determined 39,987 invertebrates (except for Protozoa) and thus recorded 575 species of 4 phyla (Ciliophora, Rhizopoda, Tardigrada, Arthropoda). Twelve taxocoenoses of ciliates, naked amoebae, water bears, pseudoscorpions, spiders, mesostigmatid mites, terrestrial isopods, centipedes, millipedes, earwigs, bugs, weevils were analysed more in detail. Apart from forest epigeon we were focused on some other microhabitats, such as decaying wood mater, mosses and dendrotelmae. Of the studied microfauna just the community from decaying wood possessed affinity to soil. In the other microhabitats (dendrotelmae and mosses) species are predominantly interacted with aquatic environment. There are stronger bonds onto soil at arthropods, represented particularly by epigeic, partially by typically edaphic species. Of the 15 analysed variables just age of a stand, depth of leaf litter, undergrowth coverness of canopy and sporadically pollution (dust from the quarry) appeared as significantly influencing the studied arthropod communities.

Abundance of the species varied between 1-33 ind.m super(-2) at the study sites. The first specimens, adults of both sexes from the previous year shortly after their overwintering appeared in the samples already in March. The first nymphal instar (N1) was sampled from the second decade of April till the end of the second decade in June. Interval of their existence took approximately 70 days. The second instar (N2) appeared from May (2nd decade) to the end of July in the period of more than 80 days. The third instar (N3) was recorded in the period of more than 75 days from June (beginning of the 2nd half) to the 1st week of September. The fourth instar (N4) was present from the beginning of July to September (1st decade) (period of more than 70 days). The first new generation adults (females and males) appeared at the end of summer (August). After winter they will form a new parental generation for the next year. The obtained data on the instars N1-N4 and length of their existence in the Male Karpaty Mts declare that the ontogenesis of C. acanthopygia from the 1st nymphal instar to imago takes 100-120 days.

A total of 3, 050 tardigrade specimens of 21 species and 2 families were gathered from 79 quantitative samples taken from 2000 and 2002. Kruskal-Wallis' tests and regression analyses showed no statistically significant influence between the 12 studied environmental variables and the number of Tardigrada specimens or number of species in the samples. A chi-square goodness of fit test suggested that the number of Tardigrada species in samples of moss Hypnum cupressiforme was random within the investigated area. A t-test of tardigrade species diversity resulted in significant differences between study sites. The group of communities with the lowest diversity does not differ mutually. Majority of differences in species diversity were caused by randomly found species. Results of cluster analysis as well as CCA point out that distribution of tardigrades and their colonisation of particular substrata is a random process. Although the results are affected by restricted number of samples, we believe that Tardigrada as passively dispersed organisms are without significant relationship to ecological variables related to their distribution amongst substrata.

For 4 seasons we were focused on selected invertebrate groups inhabiting epigeon, mosses and dendrotelmae from the coenological point of view. The study forest stands with 40-100 years of age are situated in 2 orographic units: the Male Karpaty Mts and Trnavska pahorkatina hills. Corresponding with the 3 recorded forest types (Carpinion betuli, Quercion confertae-cerris, Q. pubescentis-petraeae) we have analysed 3 soil types with different genesis and features: Rendzic Leptosols, Cambisols and Planosols. The studied stands differ in their age, anthropogenous impact and fragmentation (they represent fragmented forests in cultural environment as well as more continuous forest complexes).

The cow-calf (Bos taurus) industry in subtropical United States and other parts of the world depends almost totally on grazed pastures. Establishment of complete, uniform stand of bahiagrass (BG) in a short time period is important economically. Failure to obtain a good BG stand early means increased encroachment of weeds and the loss of not only the initial investment costs, but production and its cash value. Forage production often requires significant inputs of lime, N fertilizer, and less frequently of P and K fertilizers. Domestic sewage sludge or biosolids, composted urban plant debris, waste lime, phosphogypsum, and dredged materials are examples of materials that can be used for fertilizing and liming pastures. Perennial grass can be a good choice for repeated applications of sewage sludge. Although sewage sludge supply some essential plant nutrients and provide soil property-enhancing organic matter, land-application programs still generate some concerns because of possible health and environmental risks involved. The objectives of this study were to evaluate the cumulative and residual effects of repeated applications of sewage sludge on (i) bahiagrass (BG, Paspalum notatum Fluegge) production over years with (1997-2000) and without (2001-2002) sewage sludge applications during a 5-yr period, and (ii) on nutrients status of soil that received annual application of sewage sludge from 1997 to 2000 compared with test values of soils in 2002 (with no sewage sludge application) in South Florida. Methods. The field experiment was conducted at the University of Florida Agricultural Research and Education Center, Ona, FL (27o26'N, 82o55'W) on a Pomona fine sandy soil. With the exception of the control, BG plots received annual sewage sludge and chemical fertilizers applications to supply 90 or 180 kg total N ha-1 yr-1 from 1997 to 2000. Land application of sewage sludge and fertilizer ceased in 2001 season. In early April 1998, 1999, and 2000, plots were mowed to 5-cm stubble and treated with the respective N source amendments. The experimental design was three randomized complete blocks with nine N-source treatments: ammonium nitrate (AMN), slurry biosolids of pH 7 (SBS7), slurry biosolids of pH 11 (SBS11), lime-stabilized cake biosolids (CBS), each applied to supply 90 or 180 kg N ha-1, and a nonfertilized control (Control). Application rates of sewage sludge were calculated based on the concentration of total solids in materials as determined by the American Public Health Association SM 2540G method and N in solids. The actual amount of sewage sludge applications was based on the amount required to supply 90 and 180 kg N ha-1. Sewage sludge materials were weighed in buckets and uniformly applied to respective BG plots. Soil samples were collected in June 1997, June 1999, and in June 2002 from 27 treatment plots. In 1997 and 1999, soil samples were collected using a steel bucket type auger from the 0- to 20-, 20- to 40-, 40- to 60-, and 60- to 100-cm soil depths. Forage was harvested on 139, 203, 257, and 307 day of year (DOY) in 1998; 125, 202, 257, and 286 DOY in 1999; 179, 209, 270, and 301 DOY in 2000; and on 156 and 230 DOY in 2002 (no sewage sludge applications) to determine the residual effect of applied sewage sludge following repeated application. Forage yield and soils data were analyzed using analysis of variance (PROC ANOVA) procedures with year and treatment as the main plot and sub-plot, respectively. As a result of significant year effects on forage yield, data were reanalyzed annually (i.e., 1998, 1999, 2000, and 2002). Results and Discussion. All sewage sludges used in this study were of class B in terms of USEPA's pathogens and pollutant concentration limit. Pathogen and chemical composition of the class B sewage sludge that were used in the study were all in compliance with the USEPA guidelines. The liquid sludge (SBS11) had the lowest fecal coliform counts (0.2 x 106 CFU kg-1) while the cake sewage sludge (CBS) had the greatest coliform counts of 178 x 106 CFU kg-1. The fecal coliform counts for SBS7 was about 33 x 106 CFU kg-1. Average soil test values in June 2002 exhibited: i) decrease in TIN (NO3-N + NH4-N), TP, K, Ca, Mg, Mn, and Fe; and ii) slight increase in Zn and Cu when compared with the June 1997 soil test results. The overall decrease in soil test values in 2002 might be associated with nutrient cycling and plant consumption. Although the average BG forage yield in 2002 (2.3 plus or minus 0.7 Mg ha-1) was slightly lower than in 2000 (3.5 plus or minus 1.2 Mg ha-1), yield differences in 2002 between the control (1.2 + 0.2 Mg ha-1) and treated plots (2.3 plus or minus 0.5 Mg ha-1 to 3.3 plus or minus 0.6 Mg ha-1) were indicative of a positive residual effect of applied sewage sludge. This study has shown that excessive build up of plant nutrients may not occur in beef cattle pastures that repeatedly received sewage sludge while favoring long-term increased forage yield of BG. All sources of N (sewage sludge and AMN) gave better forage production than the unfertilized control during years with sewage sludge application (1997-2000) and also during years with no sewage sludge application (2001-2002). The favorable residual effects of applied sewage sludge in 2002 may have had received additional boost from the amount of rainfall in the area. Conclusions. Repeated applications of sewage sludge indicate no harmful effects on soil quality and forage quality. Our results support our hypothesis that repeated land application of sewage sludge to supply 90 and 180 kg N ha-1 would not increase soil sorption for nutrients and trace metals. Results have indicated that the concentrations of soil TIN and TP declined by almost 50% in plots with different nitrogen sources from June 1997 to June 2002 suggesting that enrichment of nitrogen and phosphorus is insignificant. The concentrations of soil nitrogen and phosphorus in 2002 following repeated application of sewage sludge were far below the contamination risk in the environment. The residual effect of these sewage sludge over the long term can be especially significant in many areas of Florida where only 50% of the 1 million ha of BG pastures are given inorganic nitrogen yearly. Recommendation and Outlook. Successive land application of sewage sludge for at least three years followed by no sewage sludge application for at least two years may well be a good practice economically because it will boost and/or maintain sustainable forage productivity and at the same time minimize probable accumulation of nutrients, especially trace metals. Consecutive applications of sewage sludge may result in build up of some trace metals in some other states with initial high metallic content, but in this study, no detrimental effects on soil chemical properties were detected. The possibilities for economically sound application strategies are encouraging, but more and additional research is required to find optimal timing and rates that minimizes negative impacts on soil quality in particular or the environment in general. For proper utilization of sewage sludge, knowledge of the sewage sludges' composition, the crop receiving it, are absolutely crucial, so that satisfactory types and rates are applied in an environmentally safe manner. There is still much to be learned from this study and this investigation needs to continue to determine whether the agricultural and ecological objectives are satisfied over the longer term.

AN - 20193799; 6488836 AB - Eighty-seven culturable endophytic bacterial isolates in 19 genera were obtained from coffee plants collected in Colombia (n = 67), Hawaii (n = 17), and Mexico (n = 3). Both Gram positive and Gram negative bacteria were isolated, with a greater percentage (68%) being Gram negative. Tissues yielding bacterial endophytes included adult plant leaves, various parts of the berry (e.g. crown, pulp, peduncle and seed), and leaves, stems, and roots of seedlings. Some of the bacteria also occurred as epiphytes. The highest number of bacteria among the berry tissues sampled was isolated from the seed, and includes Bacillus, Burkholderia, Clavibacter, Curtobacterium, Escherichia, Micrococcus, Pantoea, Pseudomonas, Serratia, and Stenotrophomonas . This is the first survey of the endophytic bacteria diversity in various coffee tissues, and the first study reporting endophytic bacteria in coffee seeds. The possible role for these bacteria in the biology of the coffee plant remains unknown. (2005 WILEY-VCH Verlag GmbH & Co.

We evaluated pathogen reduction in liquid swine manure in a multi-stage treatment system where first the solids and liquid are separated with polymer, followed by biological nitrogen (N) removal using nitrification and denitrification, and then phosphorus (P) extraction through lime precipitation. Each step of the treatment system was analyzed for Salmonella and microbial indicators of fecal contamination (total coliforms, fecal coliforms, and enterococci). Before treatment, mean concentrations of Salmonella, total coliforms, fecal coliforms, and enterococci were 3.89, 6.79, 6.23 and 5.73 log sub(10) colony forming units (cfu)/ml, respectively. The flushed manure contained 10, 590 mg/l TSS, 8270 mg/l COD, 688 mg/l TKN and 480 mg/l TP, which were reduced >98% by the treatment system. Results showed a consistent trend in reduction of pathogens and microbial indicators as a result of each step in the treatment system. Solid-liquid separation decreased their concentrations by 0.5-1 log sub(10). Additional biological N removal treatment with alternating anoxic and oxic conditions achieved a higher reduction with average removals of 2.4 log sub(10) for Salmonella and 4.1-4.5 log sub(10) for indicator microbes. Subsequent P treatment decreased concentration of Salmonella and pathogen indicators to undetectable level (<0.3 log sub(10) cfu/ml) due to elevated process pH (10.3). Our results indicate that nitrification/denitrification treatment after solids separation is very effective in reducing pathogens in liquid swine manure and that the phosphorus removal step via alkaline calcium precipitation produces a sanitized effluent which may be important for biosecurity reasons.

Each group consisted of four 25-g samples (three inoculated and one uninoculated). After inoculation, these samples were shipped by overnight courier in shipping containers with ice packs from the U.S. Department of Agriculture (USDA), Eastern Regional Research Center, in Wyndmoor, Pa., to the U.S. Food Safety and Inspection Service (FSIS), Eastern Laboratory, in Athens, Ga. A total of 128 samples (32 in each of four groups) were shipped. A temperature data logger was placed inside each shipping container to record the temperature during shipping and storage. The first group of ground beef samples was analyzed within approximately 1 h of arrival. The second group of samples was left in the original containers, with a gel ice pack, for 24 h before processing. The third and fourth groups of samples were removed from the original shipping containers and stored at room temperature (21 +/- 2 degree C) for 6 h and then in a refrigerator at 4 +/- 2 degree C for 24 and 48 h, respectively, before analysis. The samples were analyzed for the presence of Salmonella according to the USDA/FSIS Microbiological Laboratory Guidebook, chapter 4.02. There was no significant difference in the presence and levels of Salmonella in ground beef among the four test groups. These data show that it is acceptable to process the late- arriving ground beef samples for the detection of Salmonella if they are kept in a refrigerator (4 +/- 2 degree C) for 24 to 48 h or when the shipments arrive late (24 h in the container with ice pack).

An eight-strain cocktail of L. monocytogenes was inoculated on the surface of diced cooked ham or potato. The inoculated ham or potato was then mixed with regular mayonnaise (pH 3.8) or mayonnaise that was adjusted with NaOH to pH 4.2 or 4.6. The cell counts of L. monocytogenes in the salads during storage at 4, 8, or 12 degree C were enumerated and used to model the behavior of L. monocytogenes in ham salad or potato salad. At each of the storage temperatures, L. monocytogenes was able to grow in ham salad, whereas L. monocytogenes was inactivated in potato salad. The growth rate (log CFU per hour) in ham salad or the inactivation rate (log CFU per hour) in potato salad increased as the storage temperature increased. The duration before growth in ham salad or inactivation in potato salad increased as storage temperature decreased. The mayonnaise pH showed no consistent effect on the growth rate or inactivation rate and duration before growth or inactivation occurred. Mathematical equations that described the growth rate or inactivation rate of L. monocytogenes in both salads as a function of mayonnaise pH and storage temperature were generated and shown to be satisfactory in describing the growth rate or inactivation rate of L. monocytogenes in the ham salad or potato salad.

Yet, in 2001, 10.7% of U.S. households were estimated to be food insecure at some point during the year. Food security, poverty, and food insecurity are strongly linked by economic conditions. Job transitions, layoffs, and family disruptions result in periods of low income and vulnerability to food insecurity. Economic and food assistance programs have helped protect many U.S. households when the market economy has failed to do so. These programs have reduced vulnerability to falling income and food insecurity during economic downturns in the business cycle. However effective food assistance programs have been for reducing short-term vulnerability, they do not enhance a household's ability to achieve sustainable food security. Prospects for improving long-term food security are tied to the same economic forces shaping a household's income and budget, particularly those related to labor productivity and wages.

Results from most bacterial transport studies in soils are only partially applicable to manure-borne bacteria because microorganisms are released along with manure particulates as manure dissolves. The objective of this study was to compare transport of chloride ion, Escherichia coli (E. coli) and manure colloids in undisturbed soil columns with a well-developed structure. Breakthrough column experiments were conducted with undisturbed, 20-cm long Tyler soil columns from the A horizon. A pulse of 4% filtered bovine manure solution with E. coli and KCl was passed through the columns. Escherichia coli concentrations, chloride content, and turbidity were measured in influent and in effluent. Columns were cut into 2-cm layers after the experiment to measure: (i) viable bacterial concentrations in pore solution and attached to soil; (ii) bulk density; (iii) water content. Companion batch experiments were performed to measure attachment of E. coli to soil in the presence of various amounts of manure. Escherichia coli attachment to soil decreased with increased manure content due to increased competition for attachment sites. Flow velocity affected E. coli transport and attachment to soil; there was relatively more attachment at slower flow velocity than at higher flow velocity. Escherichia coli attachment to soil was 18, 5, and 9% at flow velocities of 2.3, 8.4, and 9.3 cm d super(-1), respectively. Spatial variability in soil structure may result in large variations of pore water velocity and consequent differences in transport of manure particulates and bacteria under ponded infiltration.

Expression (using real-time PCR) of TLR3 and TLR5 was measured for two strains of channel catfish in previously non-exposed fish 2, 5, 8, and 21 days after experimental Edwardsiella ictaluri challenge to determine if TLRs are associated with host response to E. ictaluri infection. Expression of TLR5 was higher than TLR3 (P<0.0001). TLR3 expression in kidney was elevated in Norris strain (P=0.480) and differed over time in spleen (P=0.0134). Fold induction of TLR5 compared to non-exposed fish increased on days 5 (Norris; 154.72 plus or minus 62.12 fold induction) and 8 (USDA103; 164.65[plus-or-minus-sign]50.56) post-exposure in liver and was slightly increased on day 5 (Norris; 10.17 plus or minus 24.73, USDA103; 42.56[plus-or-minus-sign]24.73) in kidney. Upregulation of TLR3 suggests a more widespread function in primitive fish. TLR5 was highly expressed in liver tissue, which may be due to macrophage aggregation during ESC infection. This suggests that toll-like receptors are an important component of the innate immune system of catfish.

In a recently published article, the clarity and consistency of the terms pathogenicity and virulence as used in invertebrate pathology were called into question, and a revision of these terms was proposed. Our objective was to examine definitions of pathogenicity and virulence and their use in invertebrate pathology, and respond to this article. Although usage of the terms pathogenicity and virulence varies, we found considerable consistency in the published definitions of these terms in the invertebrate pathology literature throughout the history of the discipline, as well as among related disciplines such as medicine and microbiology. We did not find the established definitions to be lacking in clarity or utility. Therefore, we recommend that the definition and use of these terms adhere to precedence. Specifically, pathogenicity is the quality or state of being pathogenic, the potential ability to produce disease, whereas virulence is the disease producing power of an organism, the degree of pathogenicity within a group or species. Pathogenicity is a qualitative term, an ''all-or-none'' concept, whereas virulence is a term that quantifies pathogenicity.

It now appears that Mexican Solanum species, which coevolved with P. infestans and were previously known for providing a source of R-genes, also provide a source of quantitative, rate-reducing resistance that is highly effective, stable, and durable. It is now apparent that Mexico is the center of origin not only of the potato late blight pathogen P. infestans, but also of several related Phytophthora species including P. mirabilis, P. ipomoeae, and possibly P. phaseoli. We close with the hypothesis that these Phytophthora species evolved sympatrically from one ancestral host through adaptive radiation onto their respective four host families.

Two predominant glycoalkaloids, alpha -chaconine and alpha -solanine are produced in potatoes. An antisense transgene was constructed to down- regulate glycoalkaloid biosynthesis using a potato cDNA encoding a sterol alkaloid glycosyltransferase (Sgt1). Introduction of this construct into potatoes resulted in some lines with an almost complete inhibition of alpha - solanine accumulation. This inhibition was compensated by elevated levels of alpha -chaconine and resulted in wild type total SGA levels in the transgenic lines. In vitro assays with the recombinant SGT1 isolated from yeast demonstrated that Sgt1 encodes an enzyme capable of both glucosyltransferase and galactosyltransferase activity with a preference for UDP-galactose as the sugar donor. Together this data confirms SGT1's role in vivo as the solanidine:UDP-galactose galactosyltransferase.

Polydnavirus gene GiPDV 1.1 was cloned into the pFastBac baculovirus vector under the control of the polyhedron promoter, followed by generation of recombinant bacmid-GiPDV 1.1 by site-specific transposition. The ability of each insect cell line to support recombinant PDV gene expression was estimated using reverse transcriptase-polymerase chain reaction and Western blot. Each insect cell line infected with recombinant bacmid-GiPDV 1.1 and tested in this study was capable of supporting and producing recombinant protein. Time course expression analysis showed that 72-96 h after transfection to be the optimal time for harvest of recombinant protein for each insect cell line.

The role of nonruminant, nondomestic animals in the epidemiology of paratuberculosis in cattle is unclear. To examine nonruminant, nondomestic animals for the presence of Map, 25 feral cats, nine mice (species unknown), eight rabbits (Sylvilagus floridanus), six raccoons (Procyon lotor), and three opossums (Didelphis virginiana) were collected from a midwestern dairy with known Map-infected cattle. Mycobacterium avium subsp. paratuberculosis was isolated from the mesenteric lymph node from seven of 25 (28%) feral cats. Ileum was culture- positive for three of these seven cats, and an isolation of Map was also made from the ileum of one of nine (11%) mice. Tissue samples from other species were negative as determined by Map culture; microscopic lesions consistent with paratuberculosis were not seen in any animal. Restriction fragment polymorphism analysis of isolates from cats and dairy cattle suggest interspecies transmission. The means by which interspecies transmission occurred may be through ingestion of Map-contaminated feces or waste milk or through ingestion of Map-infected prey. Shedding of Map from infected cats was not evaluated. The epidemiologic role of Map-infected feral cats on dairy farms requires further investigation.

In this study, the economic cost of illness due to O157 STEC infections transmitted by food or other means was estimated based on the CDC estimate of annual cases and newly available data from the Foodborne Diseases Active Surveillance Network (FoodNet) of the CDC Emerging Infections Program. The annual cost of illness due to O157 STEC was $405 million (in 2003 dollars), including $370 million for premature deaths, $30 million for medical care, and $5 million in lost productivity. The average cost per case varied greatly by severity of illness, ranging from $26 for an individual who did not obtain medical care to $6.2 million for a patient who died from hemolytic uremic syndrome. The high cost of illness due to O157 STEC infections suggests that additional efforts to control this pathogen might be warranted.

A greater number of mosquito species were captured in traps baited with octenol plus CO sub(2) than those baited with CO sub(2) or octenol in the saltwater marsh, Freshwater Beach. In the inland environments of Camp Growl and Raspberry Creek, the addition of octenol did not significantly increase the numbers of mosquito species captured. Trap treatment (octenol only, CO sub(2) only, or octenol plus CO sub(2)) influenced the species captured at Freshwater Beach. More Ochlerotatus vigilax, Mansonia uniformis, and Coquillettidia xanthogaster were captured in traps baited with octenol plus CO sub(2), and more Anopheles were captured in traps baited with CO sub(2) only. The most commonly captured (83%) mosquito species in the Shoalwater Bay Training Area during TT01 was the salt marsh breeder and Ross River virus vector, Oc. vigilax.

During 2003, the United States Department of Agriculture distributed more than 10 million tetracycline- containing rabies-vaccine baits to control the spread of wildlife vectored rabies to humans, pets, and livestock. To estimate the percentage of target species consuming the baits, raccoons and skunks were collected in baited areas and teeth were analyzed for the presence of the biomarker. Several incidents of low biomarker detection rates prompted an investigation of the stability of the biomarker in the baits. Baits were collected at several points along the manufacturing and distribution chain. Baits were analyzed for free and polymer- bound tetracycline and the less active isomer epitetracycline. Results indicated that a portion of the tetracycline was converted to epitetracycline. Additionally, significant quantities of both compounds were trapped in the polymer, which is homogeneously distributed throughout the bait. The results of this study suggest that approximately 40% of the target quantity of tetracycline was unavailable for absorption. This situation could contribute to low biomarker detection rates and suggests that formulation modification should be considered.

Data were collected by sponge-sampling techniques. These studies were designed to provide nationwide estimates of the prevalence of Salmonella and prevalence and concentrations of Escherichia coli in cattle (n = 1,881), swine (n = 2,127), turkeys (n = 1,396), and geese (n = 102) in establishments under federal inspection. Salmonella prevalence ranged from 1.2% in cattle to 6.9% in swine, 13.7% in geese, and 19.6% in turkeys. The prevalence of E. coli was 16.6% in cattle (geometric mean = 0.26 CFU/cm super(2)), 44.1% in swine (mean = 0.78 CFU/cm super(2)), 92.7% in turkey (mean = 2.46 CFU/cm super(2)), and 96.5% in geese (mean = 1.97 CFU/cm super(2)). These values are similar to or somewhat lower than previous baseline values obtained for steers and heifers, cows and bulls, market hogs, and young turkeys. This study is the first in which nationwide microbiological baseline data have been compiled for geese. These data will be useful to individuals working with hazard analysis critical control point plans and risk assessment and to the research and academic communities.

The apparatus consisted of a low- pressure mercury lamp surrounded by a coil of UV transparent tubing. Cider was pumped through the tubing at flow rates of 27 to 83 ml/min. The population of E. coli K-12 was reduced by 3.4 +/- 0.3 log after being exposed for 19 s at a treatment temperature of 25 degree C. The population of L. innocua, which was more resistant to UV, was reduced by 2.5 +/- 0.1 log after being exposed for 58 s. The electrical energy for the process was 34 J/ml and is similar to that for conventional thermal processing. UV processing has the potential to improve the safety and extend the shelf life of apple cider.

B. pilosicoli induces disease in both humans and animals, whereas B. aalborgi affects only humans and higher primates. Symptoms in humans include diarrhea, rectal bleeding, and abdominal cramps. Colonic spirochetosis is common in third world countries; however, in developed countries, the disease is observed mainly in homosexual males. Terminally ill patients infected with Brachyspira are particularly at risk for developing spirochetemia. Diarrhea, poor growth performance, and decreased feed-to-gain efficiency is seen in pigs with colonic spirochetosis. The disease in chickens is characterized by delayed and/or reduced egg production, diarrhea, poor feed conversion, and retarded growth. Thus, colonic spirochetosis can represent a serious economic loss in the swine and poultry industries. The organisms are transmitted by the fecal-oral route, and several studies have demonstrated that human, primate, pig, dog, or bird strains of B. pilosicoli can be transmitted to pigs, chickens, and mice. B. pilosicoli may be a zoonotic pathogen, and although it has not been demonstrated, there is a possibility that both B. pilosicoli and B. aalborgi can be transferred to humans via contact with the feces of infected animals, meat from infected animals, or food contaminated by food handlers. Neither B. pilosicoli nor B. aalborgi has been well characterized in terms of basic cellular functions, pathogenicity, or genetics. Studies are needed to more thoroughly understand these Brachyspira species and their disease mechanisms.

Design, Setting, Participants: Data from the Third National Health and Nutrition Examination Survey (NHANES III) was used (5,727 adults, 40-74 years of age: 26% Mexican Americans, 25% non-Hispanic Blacks, and 49% non-Hispanic Whites). Main Outcome Measures: Sarcopenia was defined as a skeletal muscle [SM(kg)/height(m super(2))] 102 cm in men and >88 cm in women. Results: The prevalence of diabetes was 40% higher in Mexican Americans than in non-Hispanic Blacks or Whites (P<.05). The lowest prevalence of obesity and sarcopenia were observed in Mexican Americans (except for obesity in women). Independent of ethnicity, subjects with a high waist circumference were more likely to have diabetes and poor glycemic control (P<.05). These associations were strongest in non-Hispanic Whites. Conversely, sarcopenia was not associated with diabetes or poor glycemic control in any ethnic group. Conclusions: Although the prevalence of type 2 diabetes was highest in Mexican Americans, non-Hispanic Whites exhibited the highest prevalence of obesity and sarcopenia. The role of genetically based, ethnic differences in body composition and diabetes risk needs to be taken into account when developing clinical guidelines such as the waist circumference cut-points used in this study.

The upkeep of these facilities requires continual maintenance and occasional remodeling. The superintendents and architects responsible for the maintenance and remodeling efforts need non-destructive tools for obtaining information on shallow subsurface features within parts of the golf course, particularly tees and greens. The subsurface features of importance include, but are not limited to, constructed soil layer characteristics and drainage system infrastructure. Near-surface geophysical methods can potentially provide a non- destructive means for golf course superintendents and architects to obtain the shallow subsurface information required to address their maintenance and remodeling concerns.This case study assessment of near-surface geophysical methods in regard to golf course applications focused on electromagnetic induction (EMI) and ground penetrating radar (GPR) techniques. The investigation employed two different EMI ground conductivity meters. Two GPR systems were also tested including the evaluation of antenna center frequencies ranging from 250 to 1,000 MHz. The study incorporated three separate sites. Measurements with both EMI and GPR were collected on a tee and a green at the Muirfield Village Golf Club in Dublin, Ohio, U.S.A. and on a practice green at the Golf Club of Dublin in Dublin, Ohio, U.S.A. GPR was also tested on a golf course green at the Guelph Turfgrass Institute & Environmental Research Centre in Guelph, Ontario, Canada.Results indicate that use of the appropriate EMI equipment can provide information on spatial changes of shallow apparent electrical conductivity (EC sub(a)) within golf course green constructed soil layers. This EC sub(a) data could potentially be employed to gauge constructed soil layer conditions, including wetness, salinity, etc., within different areas of a green. GPR proved quite capable of obtaining useful information on the golf course tee and greens that were studied, at least in regard to constructed soil layer thicknesses/depths or their areal extent and in locating the subsurface drainage pipe systems present. For the GPR center antenna frequencies evaluated, ranging from 250 to 1,000 MHz, all seemed to work relatively well for mapping tee and green constructed soil layer areal extent and drainage pipe locations. The higher frequency 900 and 1,000 MHz antennas appeared to work best for resolving thicknesses/depths of constructed soil layers within the tee and greens investigated. In addition, computer modeling of synthetic GPR profiles provide valuable insight and help considerably with data interpretation. While more research is certainly warranted, near-surface geophysical methods, especially EMI and GPR, appear to show promise with respect to acquiring the data needed in golf course maintenance and remodeling applications.

In general, the results from the geometrical analysis comply with those from the triple regression analysis. The smallest pumpkinseed (predominantly juveniles) differed significantly from the largest pumpkinseed (predominantly adults) in all the three populations. The major difference was that adults had a deeper body and larger belly area than juveniles, which is probably associated with more space for gonads in mature fish. Developmental patterns and external morphology in pumpkinseed from the River Otonabee seemed to be closer to pumpkinseed from the Danube than to those from Lake Looncall. This suggests that, in the pumpkinseed examined, ontogenetic changes in external shape depend on environmental conditions (epigenetical information) rather than on geographical and/or genetical isolation. Further examination of early development, fecundity, number of spawning acts per season, parental care, egg size, age at maturation, etc., will follow to test this hypothesis.

Biofilm formation is a natural process where microbial cells attach to the support (adsorbent) or form flocs/aggregates (also called granules) without use of chemicals and form thick layers of cells known as "biofilms." As a result of biofilm formation, cell densities in the reactor increase and cell concentrations as high as 74 gL super(-1 )can be achieved. The reactor configurations can be as simple as a batch reactor, continuous stirred tank reactor (CSTR), packed bed reactor (PBR), fluidized bed reactor (FBR), airlift reactor (ALR), upflow anaerobic sludge blanket (UASB) reactor, or any other suitable configuration. In UASB granular biofilm particles are used. This article demonstrates that reactor productivities in these reactors have been superior to any other reactor types. This article describes production of ethanol, butanol, lactic acid, acetic acid/vinegar, succinic acid, and fumaric acid in addition to wastewater treatment in the biofilm reactors. As the title suggests, biofilm reactors have high potential to be employed in biotechnology/bioconversion industry for viable economic reasons. In this article, various reactor types have been compared for the above bioconversion processes.

The annual census count almost tripled from 1990 to 1999. The transect and observation-based mapping method showed the same increasing trend in population between 1990 and 1999, except from 1992 to 1993. The annual official census transect count was consistently higher than the mapping method for stands censused in common. After standardizing for sample size, the annual number of Kirtland's Warblers per stand increased through time with the transect method, while there was a positive, non-significant trend with the mapping method. After 1992, the two methods began diverging in the number of males per stand. The relationship between the differences in count between methods (mapping count minus transect count) to the official transect count varied among years. At the stand level, the transect-method count was greater than the mapping count in 60% of the stands, while the mapping count was greater than the transect count in 16.3% of the stands. The difference in count between methods at the stand level ranged from -43 to +10. We illustrate the difficulties with interpreting transect counts due to Kirtland's Warblers' large territory sizes, occasional double territories, and active territorial defense during early morning hours. We suggest improvements to help correct these sources of error. We conclude that the official census transect counts are a satisfactory relative index, but results should not be interpreted as an absolute count.

The work of several experts in the field is examined closely. These individuals view industrial roundwood production as an industry that should maximize its efficiency by using as little land and producing as much wood as possible. At the same time, the assumption is held that increasing plantations will also increase environmental protection of native forests. In response to this conclusion, this paper challenges the argument that intensive forest management practices on plantations prevent the degradation of natural forests, thereby protecting the ecological values of natural forests, making plantations environmentally and socially desirable.

AN - 19498778; 7194919 AB - This paper critically examines the local community benefits associated with intensively managed industrial roundwood plantations (IMPIRs). It is based on a review of existing literature. I focus on three issues: natural resource access and control, job creation, and the effects of creating forest reserves as a corollary of establishing industrial roundwood plantations. The cases reviewed here indicate that IMPIRs often bring about land ownership concentration, loss of customary rights of resource access, rural displacement, and socioeconomic decline in neighboring communities. Beneficiaries include large rural landowners who sell or lease their land to forestry companies, and people who are able to find jobs in the forestry sector. IMPIRs do not appear to provide enough quality jobs to stimulate community development, and rarely benefit people who are already politically and economically marginalized. The paper concludes by suggesting ways in which plantation forestry can become more integrated with surrounding communities to increase local benefits.

A lack of knowledge about Harperocallis population dynamics currently hinders conservation planning. Our objectives included describing ramet size, reproductive status, and mortality and recruitment rates in natural populations of H. flava. In 1998, we established permanent plots and marked individual ramets at six sites representing two habitat types in Apalachicola National Forest. At each site, we established ge 3 plots of varying size (0.12-1.8 m super(2)) to include similar to 300 ramets / site. In the first year we tagged, recorded reproductive status of, and measured individual ramets (# of leaves, longest leaf length). In 1999 and 2000, new ramets were tagged and all tagged ramets were re-measured. Analysis of variance methods were used to detect site, year, and habitat effects on response variables. Total number of ramets sampled varied between sites and declined from year to year. The proportion of ramets bearing reproductive structures was low (0.01 to 0.10) and varied with site and year. Logistic regression indicated that larger ramets were more likely to produce reproductive structures, and that smaller ramets suffered higher mortality. There were significant habitat and year effects on mortality; recruitment differed between years. The relatively short duration of this study precluded examination of potentially important fire effects. A rhizomatous habit and unexpected levels of crayfish-induced mortality suggest that knowledge of population structure and processes at larger scales is needed to develop effective monitoring and management strategies for H. flava.

Nitrogen draining into the Gulf from the Mississippi Basin has been identified as the primary source of the problem. Reducing nitrogen loads from point and nonpoint sources in the basin is the primary goal of an action plan developed to address the problem. In this paper, we use data on point source dischargers and a model of the agriculture sector to examine whether the purchase of nitrogen reduction "credits" from nonpoint sources would reduce the cost of nitrogen control if point sources are required to reduce nitrogen discharges. Results indicate that a substantial degree of credit trading could affect agricultural commodity prices, thereby affecting agricultural production outside the basin.

The soils in the region are mainly crushed limestone with low water holding capacity, high permeability, low organic matter, and low fertility. Application of composts as a soil amendment promises improved water holding capacity and chemical retention. The USDA Everglades Agro- Hydrology Model (EAHM) has been developed to evaluate the impact of agricultural practices on crop production, water balance, and the fate and transport of nutrients and pesticides. The model was modified to simulate the effect of different types and amounts of compost applications on water balance, yield and agro-chemical transport on a typical farm in south Florida. The model was used to select the best management practices (BMPs) while considering the long-term impact of composting on soil water balance, crop yield, and the fate and transport of nitrogen and a pesticide (atrazine) on a South Florida agricultural farm. Considering the poor soil quality, the model simulation test indicated that the application of 90 to 134 T.ha-1 of compost annually will result in an increase of soil water content, crop yield, and reduced water seepage below the root zone, thus reducing the potential for N and atrazine to leach into groundwater.

Park ER - TY - JOUR T1 - Bentazone adsorption and desorption on agricultural soils AN - 19399382; 8507535 AB - Herbicide fate and transport in soils greatly depend upon adsorption-desorption processes. Batch adsorption and desorption experiments were performed with the herbicide bentazone using 13 contrasted agricultural soil samples. Bentazone was found to be weakly sorbed by the different soils, showing average Freundlich adsorption coefficients (Kf) value of 1.4 +/- 2.3 mg 1-n sub(f) L n sub(f) kg super(-1). Soil organic matter content did not have a significant effect on bentazone sorption (r super(2) = 0.12), whereas natural soil pH appeared to be a key factor (r super(2) = 0.68). A large part (average of 96.9 +/- 4.1%) of the sorbed bentazone was released into aqueous solution after successive desorption steps, although some hysteresis was observed for each soil. Whereas soil pH was found to also influence bentazone desorption, other soil properties did not show well-defined relationships with sorption.

Merr.). Soybean produces inadequate crop residue for soil conservation purposes in many production years. Crop residues left on the soil surface after harvest slow soil erosion rates. The CAI remote sensing technique was tested over field plots of conventional and large biomass soybean (LBS) with known above ground crop residue biomass and surface coverage. New LBS types are being bred and tested at the Beltsville Agricultural Research Center (BARC), Beltsville, Maryland, US, and can grow to heights of 1.8 m and produce increased amounts of crop residue compared to conventional cultivars. The highest performing LBS line for these traits provided 2963 kg/ha more crop residue biomass and provided a maximum increase of 42% more crop residue cover than the poorest performing conventional soybean. The comparison of LBS versus conventional soybean provided a wide range of soybean residue coverage for testing the CAI remote sensing algorithm. Spectrally derived CAI measures of crop residue were significantly associated with physical ground measurements of crop biomass at harvest and % cover after over wintering. Significant correlations were found between, the CAI and at harvest biomass (r super(2) = 0.66), between, the CAI and the line point transect measurement (r super(2) = 0.74), and between, CAI and the analysis of red-green-blue digital imagery (r super(2) = 0.74) for measuring crop residue cover. These findings indicate that LBS can increase crop residue biomass and crop residue soil coverage by soybean litter and these factors can be detected by remote sensing methods in the field.

However, studies have shown that guajillo contains phenolic amines and alkaloids, and condensed tannins, which may cause toxicosis and reduced fertility, intake, and nutrient digestibility. To examine the nutritional value of guajillo to white-tailed deer (Odocoileus virginianus Zimmermann) more thoroughly, we present a comparison of mixed diets of 0%, 25%, 50%, and 75% guajillo in male white-tailed deer. Four in vivo metabolism trials were completed with each diet. Dry matter intake and change in body mass did not differ among diets. Gross and digestible energy intakes did not differ among diets, whereas metabolizable energy intake decreased with increased dietary guajillo concentration. Nitrogen balance and digestibility decreased with increased dietary guajillo concentration. Urinary glucuronic acid excretion increased linearly with increased dietary guajillo concentration. Nitrogen requirements for body growth and antler development were met by diets containing <60% guajillo, whereas energy requirements for maintenance and antler growth were met with diets containing <20% guajillo. Therefore, concentrations of dietary guajillo <20% will support the maintenance of white-tailed deer. The primary function of guajillo may be to facilitate maintenance of adult deer, which have fewer obligatory productive processes than young deer, during periods of drought.

In 136 samples 94 taxa of ciliates were found. Ciliates were not detected in 2 tree-holes only. An average of 3-6 species were presented in a single tree-hole, but the diversity was very irregular (0-15 species). Similarly, abundance was very irregular too and rapidly oscillated between 0-200,000 ex/ml. The frequency of individual species in the samples did not overlap the value of 30%. The highest frequency was recorded at the species Leptopharynx costatus (28.68%) and Sathrophilus mobilis (27.21%). Specifically, subclass Peritrichia was over-represented (notably species of the genera Propyxidium and Scyphidia). On the basis of Canonical Correspondence Analysis (CCA) (15 nominal and 2 gradient variables were analysed, 9 of them were statistically significant) 4 principal communities of ciliates have been distinguished. A tree species, volume and age of a tree-hole, absence of rotifers and other metazoans were revealed as critical factors with an influence on composition of the ciliate taxocoenoses. The results were evaluated by hierarchical classification (complete linkage) as well. Tree-holes of Quercus dalechampii have reached the highest species richness and were completely different from the others (Acer campestre and Carpinus betulus). Tree-holes with a volume under 1 ml and those over 500 ml had the lowest species diversity and a special position among the others. According to the age of tree-holes, the youngest and the oldest ones were linked in one cluster by Wishart's index, meanwhile the special position in the freshest tree-holes only was validated by Soerensen's index. Thus the sense of time factor on a species structure of ciliate communities in tree-holes was revealed.

Nest density in shrubs was strongly correlated with the density of natural perch sites. This relationship occurred in 2 vegetation types with differing shrub composition. The correlation was stronger in areas with a homogenous shrub layer. Nest density was also higher in plots with artificial perch sites than in adjacent control plots. Nest density increased between years in plots where artificial perch sites were constructed but remained the same in adjacent control plots. Knowledge of perch-site effects has practical management applications in areas where doves nest in shrubby habitat. The possibility exists that perch sites could be managed for nest density in these habitats.

We related population demographic data collected from 1993 to 1996 to on-site precipitation data on the Orchard Training Area west of Boise. We also carried out field seed-retrieval and in situ seed bank studies. We found that L. papilliferum has a dual life history strategy. A fraction of each cohort sets seed as summer annuals, while the remaining plants remain vegetative and potentially biennial. Surviving biennials flower and set seed along with the annual cohort of the following year. The switch to flowering as an annual appears to be based on threshold rosette size. Probability of survival to flowering was much lower for biennials than for annuals of the same cohort, but surviving biennials sometimes had enhanced seed production. The summerdry environment of the Snake River plains combined with the slick spot habitat has apparently selected for a primarily summer annual life cycle for this species. Seeds were highly dormant at dispersal and were not responsive to dormancy-breaking cues. Those from a given cohort of L. papilliferum remained viable in the soil for at least 11 years. This persistent seed bank provides a buffer against extinction in sequences of years when seed production is low or absent. Estimated seed bank size varied from near zero for a heavily disturbed site that formerly supported the species to 18 viable seeds times dm super(-2) for an extant population in high-quality habitat. Management for population preservation for L. papilliferum should focus on protecting the seed bank from destruction caused by livestock trampling and other anthropogenic disturbances.

Various communities of indigenous microorganisms in any particular soil have adapted to the specific environmental conditions. If the soil around the plant roots could be altered to favor the indigenous soil microorganisms relative to the plant pathogen, the survival and proliferation of indigenous soil microorganisms, and thus effectiveness of biological control, may be increased. Wood chip-polyacrylamide (PAM) cores were used to alter the soil environment in a greenhouse study to favor indigenous soil microorganisms in vegetable and manure compost to reduce Verticillium dahliae infection of potato (Solanum tuberosum L.) plants. Potato plants growing in soils amended with vegetable compost-wood chip-PAM cores had significantly lower visible (V sub(vis)) and isolation (V sub(iso)) V. dahliae infection rates than control soils and soils with dairy or vegetable compost alone. Soils amended with wood chip-PAM-dairy compost cores had significantly lower V sub(vis) and isolation V sub(iso) than control soils and soils with dairy compost. Soils with wood chip-PAM cores and soils with wood chip-PAM-vegetable compost had greater microbial biomass/Verticillium dahliae biomass (MB/VB) ratios in soil than control soils or in soils amended with compost alone. MB/VB ratios in wood chip-PAM cores and wood chip- PAM-vegetable compost were greater than in wood chip-PAM-dairy compost cores. V sub(vis) correlated in a quadratic relationship with the MB/VB ratio (r super(2)=0.76). As MB/VB ratio increased V sub(vis) decreased. Although field studies with several crops and economic evaluations are necessary, this greenhouse study provides evidence that a wood chip-PAM or wood chip- PAM-vegetable compost soil amendment may be a viable method to control some soil diseases in high value crops.

This research was the second of a series of studies investigating the impacts of varying seasonal droughts on northern Great Plains rangelands. Research was conducted on native rangeland during the 1998 through 2001 growing seasons. Study plots were twelve 5 x 10 m nonweighing lysimeters. An automated rainout shelter was used to establish drought conditions on 6 lysimeters during April, May, and June of 1998 and 1999. Single-day, flash grazing events were imposed at the beginning of May, June, and July. Grazing treatments were 1) graze during the 2 years of drought and the year after; 2) graze during the 2 years of drought and rest the year after; and 3) rest all years. Results showed that the intense spring drought reduced soil water content in the upper 30 cm of the soil profile and subsequently reduced total herbage production 20% to 40%; cool-season perennial grasses were the primary contributor to the reduction and cool-season annual grasses were secondary. Periodic grazing during drought had minimal impact on herbage production, whereas impacts on nondrought plots ranged from moderate enhancement to moderate suppression, with effects varying depending on functional group. Results also showed that substantial recovery occurred during the 1st postdrought year, with near full recovery realized within 2 years.

Acidic soils from the west end of the range are N- saturated and have elevated rates of N-mineralization, nitrification, and nitrate leaching. We assessed the impact of this heavy nitrogen load on autotrophic ammonia-oxidizing communities by investigating their composition, abundance, and activity. Analysis of 177 cloned beta -Proteobacteria ammonia oxidizer 16S rRNA genes from highly to moderately N-impacted soils revealed similar levels of species composition; all of the soils supported the previously characterized Nitrosospira clusters 2, 3, and 4. Ammonia oxidizer abundance measured by quantitative PCR was also similar among the soils. However, rates of potential nitrification activity were greater for N-saturated soils than for soils collected from a less impacted site, but autotrophic (i.e., acetylene- sensitive) activity was low in all soils examined. N-saturated soils incubated for 30 days with ammonium accumulated additional soluble ammonium, whereas less- N-impacted soils had a net loss of ammonium. Lastly, nitrite production by cultivated Nitrosospira multiformis, an autotrophic ammonia-oxidizing bacterium adapted to relatively high ammonium concentrations, was significantly inhibited in pH-controlled slurries of sterilized soils amended with ammonium despite the maintenance of optimal ammonia-oxidizing conditions. Together, these results showed that factors other than autotrophic ammonia oxidizers contributed to high nitrification rates in these N-impacted forest soils and, unlike many other environments, differences in nitrogen content and soil pH did not favor particular autotrophic ammonia oxidizer groups.

The effect of shrub invasion on CO sub(2) fluxes in Northern Great Plains grasslands is not known. The objectives of this research were to determine CO sub(2) and water vapor fluxes over a grazed mixed-grass prairie (prairie site) and a mixed-grass prairie that has extensive invasion of shrubs (shrub prairie site). The Bowen ratio/energy balance (BREB) technique was used to determine CO sub(2) and water vapor (ET) fluxes during a 4-year period from 1 May to 17 October in 1999, 2000, 2001, and 2002. Aboveground biomass and leaf area index (LAI) were measured about every 21 days throughout the growing season. Peak biomass occurred during July to early August and averaged 1 763 kg . ha super(-1) for the prairie and 1 808 kg . ha super(-1) for herbaceous locations in the shrub prairie site. LAI of the herbaceous locations averaged 0.39 for the prairie site and 0.56 for the shrub prairie site. LAI for the shrubs in the shrub prairie site averaged 4.28. Total growing season CO sub(2) fluxes were similar in prairie and shrub prairie sites, averaging about 350 g CO sub(2) . m super(-2) (positive flux is CO sub(2) uptake). However, the presence of shrubs altered the seasonal pattern of fluxes. Carbon dioxide fluxes over the shrub prairie site were higher than over the prairie site early in the growing season in May and June, and were often lower than those of the prairie site late in the growing season in August, September, and October. Evapotranspiration rates from May to mid-October were higher in the prairie (521 mm) than the shrub prairie site (461 mm). These results suggest that shrub invasion on Northern Great Plains grasslands does not reduce the potential of grasslands to sequester atmospheric CO sub(2).

A total of 2,421 flies belonging to 14 Pseudacteon species were found at 51% of the 662 fire ant mounds examined at 125 collecting sites. Flies occurred in a variety of habitats at altitudes from sea level to 2,280 m. Pseudacteon obtusus Borgmeier (large form) was found at the highest altitude and at the most western longitude. Flies were active between 16 and 37 degree C, 20 and 90% RH, and 0 and 11.6 km/h wind speed. Pseudacteon curvatus Borgmeier showed the highest abundance and one of the broadest geographical distributions. Pseudacteon tricuspis Borgmeier, P. litoralis Borgmeier, the large form of P. obtusus, P. nudicornis Borgmeier, and P. nocens Borgmeier also were widely distributed. These species seem to be the most generalized within saevissima-group. Pseudacteon solenopsidis Schmitz was only collected attacking isolated workers. A new Pseudacteon species was discovered in northwestern Argentina. Seven fly species were reported for the first time on a new fire ant host in this region. Pseudacteon cultellatus Borgmeier was found for the first time on Solenopsis invicta Buren in Corrientes province in northeastern Argentina, where up to nine fly species have been found to cooccur. Males of P. tricuspis and P. obtusus were the only males normally attracted to disturbed fire ant colonies.

Performance of Deet, Bayrepel[reg.], and SS-220 insect repellents in the new in vitro system was compared with their performance on humans against mosquitoes using our standard in vivo system. For each compound, in vitro dose-response assays were conducted with compounds applied to cloth positioned over blood reservoirs covered with Baudruche membrane against Aedes aegypti. The repellents were also tested in vitro against Anopheles stephensi and Ae. aegypti at a fixed dose of 24 nmol compound/cm super(2) cloth over the Baudruche and Edicol collagen membranes. Concurrently, the repellents were tested at the fixed dose using the K&D module on human volunteers. The observed proportions of both mosquito species deterred from biting in the fixed doses in the in vitro assays were similar to those obtained using humans, being clearly able to distinguish controls from repellents, and differing only in the ranking of the effectiveness of some of the repellents. Dose-response relationships of the in vitro and in vivo systems were also very similar, although not directly comparable because the data were not collected concurrently. This new in vitro assay system can be used in high throughput screening of compounds to identify new repellents having potential for use as topical mosquito repellents on humans.

Major ecological and behavioral topics are species- and gender-recognition, nestmate recognition, task-specific cues, dominance and fertility cues, chemical mimicry, and primer pheromones. Major biochemical topics include chain length regulation, mechanism of hydrocarbon formation, timing of hydrocarbon synthesis and transport, and biosynthesis of volatile hydrocarbon pheromones of Lepidoptera and Coleoptera. In addition, a section is devoted to future research needs in this rapidly growing area of science.

Such infectious doses are a result, in part, of the quantity of cells that are ingested and that survive human host defenses, such as the low-pH environment of the stomach. To more fully understand the kinetics of E. coli O157:H7 survival in gastric fluid, individual E. coli O157:H7 strains were suspended in various media (i.e., saline, cooked ground beef [CGB], and CGB containing a commercial antacid product [CGB+A]), mixed at various proportions with simulated human gastric fluid (SGF), and then incubated at 37 degree C for up to 4 h. The highest inactivation rate among nine E. coli O157:H7 strains was observed in saline. Specifically, the average survival rates in 100:1 and 10:1 proportions of SGF-saline were -1.344 +/-0.564 and -0.997 +/-0.388 log sub(10) CFU/h, respectively. In contrast, the average inactivation rate for 10 E. coli O157:H7 strains suspended in 10:1 SGF-CGB was -0.081 +/-0.068, a rate that was 12-fold lower than that observed for SGF-saline. In comparison, the average inactivation rate for Shigella flexneri strain 5348 in 100:1 and 10:1 SGF-saline was -8.784 and -17.310, respectively. These latter inactivation rates were 7-to 17-fold higher than those for E. coli O157:H7 strains in SGF-saline and were 4- fold higher than those for E. coli O157:H7 strains in SGF-CGB. The survival rate of E. coli O157:H7 strain GFP80EC increased as the dose of antacid increased from one-half to twice the prescribed dose. A similar trend was observed for the matrix pH over the range of pH 1.6 to 5.7, indicating that pH is a primary factor affecting E. coli O157:H7 survival in SGF-CGB+A. These results can be used in risk assessment to define dose-response relationships for E. coli O157:H7 and to evaluate potential surrogate organisms.

This method circumvents the traditional use of aphids to transmit CMV, a virus that is mechanically transmissible to many plant species but only with difficulty to gladiolus. Cartridges containing virus-coated gold microcarriers were prepared and the virus shot into Nicotiana benthamiana leaves and gladiolus corms and cormels. The biolistic procedure successfully transmitted three CMV isolates, two from serogroup I and one from serogroup II. Survival rates of two cultivars of gladiolus cormels and corms in sterile and non-sterile environments were compared. Infection rates of 100% were obtained when as little as 2 mu g of virus was used in cartridge preparation. CMV remained viable after the cartridges were stored for many months at 4 super(o)C.

In this study, synthetic CpG-ODNs were evaluated for their in vitro stimulation of leukocyte and in vivo protection against Salmonella enteritidis (SE) in neonatal chickens. Our studies showed that CpG-ODN stimulated bactericidal activities, releasing granules (degranulation) and generating reactive oxygen species (oxidative burst), in chicken heterophils and up regulated nitric oxide production in chicken peripheral blood monocytes. When day-old chickens were given (i.p.) synthetic CpG-ODNs followed by oral challenge of SE, a significant reduction (p0.05) of organ invasion by SE was observed in chickens pretreated with CpG-ODN containing the immunostimulatory GTCGTT motif. This CpG-OND also significantly reduced mortality of chickens with acute peritoneal infection of SE. Our study provides evidence that immunostimulatory CpG-ODN stimulated innate immune activities and enhanced the resistance to infectious pathogens in neonatal chickens.

To determine the incidence of SbDV in Illinois, we collected clovers and forage legumes in a total of 49 Illinois counties in 2001 and 2002 and tested them for the presence of SbDV by reverse-transcription-polymerase chain reaction. SbDV was detected in 43% of red clover (Trifolium pratense), 10% of white clover (T. repens), and 3% of yellow sweet clover (Melilotus officinalis) plant samples. The dwarfing strain (SbDV-D) was the predominant strain detected in Illinois. In 2000, Aphis glycines, an aphid species that colonizes soybeans, was reported for the first time in North America. To determine whether A. glycines or aphid species found colonizing clover were vectors of SbDV, transmission studies were conducted. Aphids of the species Nearctaphis bakeri reproducibly vectored SbDV among red clovers, and from red clover to soybean.

The main characters that distinguish the various stages are body size, number of tarsomeres and tibial spines, color, and number of teeth on the metatibial spur. New biological data based on laboratory rearing and field observations show that M. scutellaris can carry out its biological cycle successfully on water hyacinth, Eichhornia crassipes (Martius) Solms Laubach (Pontederiaceae). Mating occurs close to the water level and one to four eggs per scar are laid in apical portion of petiole and pseudolaminae. Ovipositional scars are recognized by three parallel marks. In addition, the efficient rearing in captivity, the high survivorship registered, and overwintering on only water hyacinth suggest M. scutellaris as a potential biocontrol agent of this invasive aquatic weed.

Due to large amounts of land surface and rainfall heterogeneity, such information is difficult to obtain from existing ground- based networks of soil moisture sensors. Using ground-based field data collected during the Soil Moisture Experiment in 2002 (SMEX02), the potential for using distributed modeling predictions of the land surface as an upscaling tool for field-scale soil moisture observations is examined. Results demonstrate that distributed models are capable of accurately capturing a significant level of field-scale soil moisture heterogeneity observed during SMEX02. A simple soil moisture upscaling strategy based on the merger of ground-based observations with modeling predictions is developed and shown to be more robust during SMEX02 than upscaling approaches that utilize either field-scale ground observations or model predictions in isolation.

Losses caused by the disease are usually seen as a postharvest rot with orange spore masses appearing on the surface of affected fruit. One hundred cultivars/selections of blueberry were screened for resistance to fruit rot between 1993 and 2003 by inoculating container-grown plants bearing green fruit. Visible rot symptoms on ripe fruits were evaluated after a 1-week incubation at room temperature. Our analyses revealed that infection levels were affected by mean May temperatures in New Jersey, generally increasing as temperatures increased; however, this effect was not consistent among all cultivars. A generalized linear mixed model was developed to predict resistance at the historic mean May temperature, conservatively explaining 59% of the variance in resistance. Percent infection ranged from 9 to 91% with a mean of 51% across all cultivars. Results for common cultivars corresponded well with field reports of their relative susceptibilities. An estimate of narrow-sense heritability of 0.32 suggested additive inheritance of resistance. Since very high inoculum loads were used in this study, cultivars exhibiting a low percentage of fruit rot are predicted to show superior field resistance to the disease and will be incorporated into an ongoing breeding program.

The experiment was repeated in 2001. Sphacelia associated with infected sorghum panicles were placed in nylon mesh bags and either buried at a 10-cm depth, placed on the soil surface, or suspended 61 cm above the ground. Samples were recovered after 4, 8, and 12 months and assessed for pathogenicity of surviving macroconidia by macerating tissue in water and spraying it onto panicles of flowering male-sterile sorghum in the greenhouse. Survival of ergot macroconidia in recovered panicles declined at all locations after the first 4 months that panicles were left in the field. The decline in viability during this period was greater in 2001 than in 2000. In 2000, survival after 4 months was greatest at Lubbock and Bushland, which have a continental steppe climate, than at the other three Texas locations, Weslaco and Corpus Christi, which have a subtropical subhumid climate, and College Station, which has a subtropical humid climate. However, this difference in survival was not as pronounced in 2001. Additionally, after 8 months, survival levels at all locations were similar. At the end of 12 months, infective macroconidia were found only at Lubbock in 2000, and only at Lubbock and College Station in 2001. Ergot macroconidia can survive in all major sorghum production areas of Texas; thus, conidia would not need to move long distances in order to initiate an epiphytotic.

R.Br. (Old World climbing fern), in the family Schizaeaceae, is one of the most invasive (Category I in Florida) weeds in Florida. It has invaded more than 50,000 ha of wetlands and moist habitats in southern Florida and is rapidly spreading in new areas of the Everglades. The search and evaluation of biocontrol agents for this fern is currently in progress. Puccinia lygodii (Har.) Arth. (Uredinales), previously recorded on L. volubile Sw. and L. venustum Sw. in South America, attacks foliage and severely damages L. japonicum Thunb. (Japanese climbing fern) vines in northern and central Florida. We hypothesized that since L. japonicum occurred mainly in northern and central Florida, P. lygodii did not have opportunity to interact with L. microphyllum, which primarily occurs in southern Florida. Therefore, we used two inoculation methods to test the possible pathogenicity of P. lygodii on the new host, L. microphyllum. Method-I was designed to imitate a seminatural inoculation technique in which three containerized (0.45-L capacity) L. microphyllum test plants (15- to 30-cm-high sporelings) were intermixed among a group of containerized (5.0-L capacity) P. lygodii-infected L. japonicum plants (source of inoculum) in a glasshouse. In Method-II, uredospores obtained from pustules on diseased L. japonicum foliage were adjusted to 1 x 10 super(6) uredospores/ml and then misted on three L. microphyllum sporelings (same size as in Method-I) until foliage was completely wet. The plants were then covered individually with a plastic bag for 3 days to facilitate spore germination and infection. In both methods, three L. japonicum sporelings of similar size as L. microphyllum were intermixed among diseased L. japonicum plants as a positive control. All test and infected plants were placed on 6-cm-high trays filled two-thirds with water and exposed to diffused daylight and a temperature range of 20 to 35 degree C in a glasshouse. These plants were monitored for the development of rust symptoms (halos and rust pustules) development for 8 weeks. Minute cinnamon flakes that developed into eruptive pustules were seen on the lower surface of the pinnules approximately 42 and 28 days after treatment initiation (in both methods) for L. microphyllum and L. japonicum (positive control), respectively. Each method was repeated twice. Dimensions (29.7 [ plus or minus 3.7] x 23.5 [ plus or minus 2.6] mu m) and morphology of urediniospores from pustules on inoculated L. microphyllum were similar to those reported for P. lygodii on other host systems. To our knowledge, this is the first report demonstrating the infection of P. lygodii on L. microphyllum. The potential use of P. lygodii as a classical biocontrol agent of L. microphyllum in southern Florida will be further investigated.

The wind/rain-splash events were simulated using electric blowers to generate turbulent wind (15 to 20 m s super(-1)) and sprayer nozzles to produce water droplets entrained in the wind flow. The splash was blown at an inoculum source of canker-infected trees 1 m downwind. The splash downwind of the source of the infected trees was collected by vertical panel samplers and funnel samplers. The duration over which bacteria were dispersed in spray was assessed in continuous wind at intervals from 0 to 52 h after commencing the simulated rain splash event. In one experiment on 11 February 2003, a total of 1.48 x 10 super(6) bacteria were collected by panels 1 m downwind from the inoculum source during the first 10 min of dispersal, but the numbers declined to 3.60 x 10 super(5) bacteria after 1 h and ranged between 1.42 x 10 super(5) and 1.93 x 10 super(4) up to 52 h. In a more detailed study (15 July 2003) of dispersal duration over 4 h, the greatest quantity of bacteria collected by panel samplers were dispersed in the first 5-min period (1.01 x 10 super(8) bacteria collected). By 10 min after initiation of dispersal, approximately one-third (3.09 x 10 super(7) bacteria collected) of the initial number was being dispersed, and by the end of the first hour, only one-tenth (1.31 x 10 super(7) bacteria collected) of the initial quantity was dispersed. Funnel samplers placed at ground level under the trees showed a similar trend. The distance to which bacteria were dispersed in wind-blown splash was also tested under simulated conditions: on 18 September 2003, bacteria were collected by panel samplers at all distances sampled (1, 2, 4, 6, 8, 10, and 12 m) with the greatest number of bacteria deposited at 1 m (4.93 x 10 super(6) bacteria collected), while 2.22 x 10 super(3) bacteria were deposited over a 10-min period 12 m from the inoculum source. Wind speed declined from 19.5 m s super(-1) upwind of the trees to 2.8 m s super(-1) 1 m downwind, and by 4 m downwind from the inoculum source, movement was similar to the surrounding air. The data on duration and distance of dispersal were best described by power law regression models compared to exponential models.

In LLC-PK sub(1) cells, FB sub(1) inhibits cell proliferation and induces apoptosis, which can be prevented by inhibitors of serine palmitoyltransferase (SPT). Inhibition of SPT prevents the FB sub(1)- induced accumulation of free sphinganine, a precursor of ceramide biosynthesis. However, not all of the effects of FB sub(1) in LLC-PK sub(1) cells can be explained solely by the increase in free sphingoid bases. The downstream signaling pathways that are affected by FB sub(1)-induced di Sruption of sphingolipid biosynthesis are not well understood. This study determined, in LLC-PK sub(1) cells, changes in p42 MAP kinase (phosphorylated ERK2 [pERK2]) phosphorylation in response to various inhibitors of key enzymes of the de novo sphingolipid biosynthesis pathway (CS, SPT, and glucosylceramide synthase [GlcCer synthase]). The results show that inhibition of any of the three enzymes caused a similar decrease in the extent of phosphorylation of ERK2 with no reduction in total ERK2. The co-treatment of FB sub(1) (CS inhibitor) with SPT inhibitors or the GlcCer synthase inhibitor had no effect on the FB sub(1)-induced reduction in pERK2 phosphorylation, indicating that FB sub(1)-mediated changes in phosphorylation of pERK2 was independent of increases in free sphinganine or its metabolites or a reduction in ceramide. Nonetheless, the decrease in pERK2 phosphorylation was dependent on inhibition of de novo sphingolipid biosynthesis. Decreased pERK2 activity could contribute to the physiological effects of FB sub(1) in LLC-PK sub(1) cells that are not due to alteration in pathways modulated by free sphingoid bases and their metabolites but are sensitive to inhibition of glycosphingolipid biosynthesis.

At various times during refrigerated storage, samples were taken and a determination made of (a) total microflora, (b) L. monocytogenes, (c) headspace gas composition, (d) color and (e) texture. Irradiation reduced initial microbial counts in a dose-dependant manner. Bacteria regrew during storage on Air-0 samples, but not on 5/5 or 10/10 samples. In each of the three atmospheres, O sub(2) declined and CO sub(2) increased, irrespective of radiation dose. Irradiated leaf material in Air-0 tended to retain color attributes during storage better than non-irradiated; color retention was more variable under 5/5 and 10/10 packaging. After 8 days, maximum shear force relative to the initial level was significantly reduced in 5/5 at all radiation doses, was not significantly changed in Air-0, and was dose-dependent in 10/10. By 14 days, the texture of all samples had degraded significantly. These results indicate that irradiation and modified atmosphere packaging can be combined to prevent the regrowth of L. monocytogenes during post-irradiation refrigerated storage, thereby improving product safety.

The model is designed primarily for use in forecasting pathogens that do not have extensive epidemiological data. Most existing infection models require a background epidemiological data set, usually including laboratory estimates of infection at multiple temperature and wetness combinations. The model developed in this study can use inputs based on subjective estimates of the cardinal temperatures and the wetness duration requirement. These inputs are available for many pathogens or may be estimated from related pathogens. The model uses a temperature response function which is scaled to the minimum and optimum values of the surface wetness duration requirement. The minimum wetness duration requirement (W sub(min)) is the number of hours required to produce 20% disease incidence or 5% disease severity on inoculated plant parts at a given temperature. The model was validated with published data from 53 controlled laboratory studies, each with at least four combinations of temperature and wetness. Validation yielded an average correlation coefficient of 0.83 and a root mean square error of 4.9 h, but there was uncertainty about the value of the input parameters for some pathogens. The value of W sub(min) varied from 1 to 48 h and was relatively uniform for species in the genera Cercospora, Alternaria, and Puccinia but less so for species of Phytophthora, Venturia, and Colletotrichum. Operationally, infection models may use hourly or daily weather inputs. In the case of the former, information also is required to estimate the critical dry-period interruption value, defined as the duration of a dry period at relative humidities <95% that will result in a 50% reduction in disease compared with a continuous wetness period. Pathogens were classified into three groups based on their critical dry-period interruption value. The infection model is being used to create risk maps of exotic pests for the U.S. Department of Agriculture's Animal Plant Health and Inspection Service.

The ELIME technique entails sandwiching bacterial analyte between antibody-coated magnetic beads and an alkaline phosphatase-conjugated antibody. The beads (with or without bound bacteria) were localized onto the surface of magnetized graphite ink electrodes in a multiwell plate format. The enzyme substrate, 1-naphthyl phosphate, was added, and conversion of substrate to an electroactive product was measured using electrochemical detection. With this technique, detection of whole, live E. coli O157:H7 bacterial cells was achieved with a minimum detectable level of ca. 5 x 10 super(3) cells per ml in Tris-buffered saline or buffered apple juice in an assay time of ca. 80 min. With adjustment of pH, the ELIME response for the bacteria in either sampling medium was similar, indicating that apple juice components did not contribute to any discernible sample matrix effects.

One popular type of sandwich product is the tortilla wrap, which contains sliced luncheon meats and cheeses rolled within a flour tortilla. This study determined the radiation resistance of L. monocytogenes surface inoculated onto two types of commercially available wheat flour tortillas, processed cheese slices, and deli turkey meat. The D sub(10)-values for L. monocytogenes (the radiation dose required to inactivate 1 log of the pathogen) were 0.27 kGy when inoculated onto two flour tortilla types, 0.28 and 0.30 kGy when inoculated onto two types of sliced processed cheeses, and 0.58 and 0.65 kGy when inoculated onto two types of sliced deli turkey meat. When two types of tortilla wraps were assembled from the individual components and L. monocytogenes was inoculated into the interfaces between the individual components, the D sub(10)-values were 0.27 to 0.37 kGy in the tortilla and cheese interfaces, 0.33 to 0.41 kGy in the cheese and turkey interfaces, and 0.25 to 0.33 kGy in the turkey and tortilla interfaces. The ability of ionizing radiation to reduce pathogen levels on the complex tortilla, cheese, and luncheon meat product was limited by the higher radiation resistance of L. monocytogenes when inoculated onto the ready-to- eat turkey-meat component.

The fungus functions as an endophyte, a fungal/host interaction beneficial to the growth of some plants. At other times, the fungus may function as a mycotoxin producing pathogen. The advantages and/or disadvantages of the endophytic relationship must be established in order to target appropriate sites for controlling diseases and mycotoxins in maize. One possibility could be to ensure seed maize is fungal free prior to planting. Reciprocal inoculations were made with two fungal isolates on seed of two maize genotypes. Yield was measured at harvest by ear and seed characters and vegetative growth at one-month intervals for plant survival, height, weight and stem diameter. Yield and vegetative growth differed among mature plants only once based on seed inoculation status. In 1998, plant weight was reduced and seed weight per ear was increased for the dent maize, GT-MAS: gk, grown from F. verticillioides RRC 374- inoculated seed compared to other seed treatments. Most vegetative characters were reduced at the first collection for Silver Queen plants grown from F. verticillioides-inoculated seed in 1997 and 1999, but not in 1998. However, no significant differences occurred among mature Silver Queen plants during any of the three growing seasons. In conclusion, yield and vegetative growth of mature maize plants grown from F. verticillioides-inoculated seed were equal to or greater than plants grown from non-inoculated seed under south Georgia field conditions during 1997, 1998, and 1999.

It colonizes lentic or slow moving, fresh water bodies like ponds, lake, swamps, and marshes. The native range of this species encompasses Central and South America. It is adventive in Bermuda, Puerto Rico, and Spain. Jacono et al. (2001) documented multiple introductions of this species in North America where it now occurs in at least 7 states and 69 drainages.

Considering the economic importance of fishes susceptible to S. agalactiae throughout the world, an efficacious S. agalactiae vaccine was developed using an extracellular product (ECP) fraction and formalin-killed whole cells of S. agalactiae. A vaccine study was conducted by intraperitoneal (i.p.) injection in Nile tilapia Oreochromis niloticus in order to determine the duration of protection and its correlation to antibodies specific for this pathogen. After 47, 90 or 180 d post-vaccination (DPV), the fish were i.p. challenged with approximately 2.0 x 10 super(4) S. agalactiae colony-forming units (CFU) fish super(-1) to determine the duration of protective immunity. The percent survival in control fish i.p.-injected with sterile TSB was 16, 16, and 4% on 47, 90 and 180 DPV, respectively, while the percent survival for the vaccinated fish was 67, 62 and 49%, respectively. The specific mean antibody concentration of the vaccinated fish was significantly higher than that of the control fish, with significant correlation between the ELISA optical density (OD) and protection. These results indicate that the specific antibody has a correlation with protection following immunization with the S. agalactiae vaccine and that the vaccine can confer protection against S. agalactiae up to 180 DPV.

Seed viability was determined over different burial durations in the soil through a combination of germination tests and 2,3,5- triphenyl-tetrazolium chloride (TTC) treatments. Control seeds kept dry at 25 C in the laboratory maintained same viability of ca. 15% over the 3-year study. In the field, seed viability decreased with increased burial duration. Most buried seeds lost viability by ca. 1.5 year at seasonally flooded and permanently flooded sites, whereas seeds buried at non-flooded sites survived over a period up to 2 to 2.3 years. Burial depth increased seed viability at the non-flooded sites (P < 0.0001), but had little effect on viability at seasonally (P = 0.3691) and permanently flooded sites (P = 0.0735). Soil types also had significant effect on seed viability. Seeds buried in organic (muck) soils decreased viability significantly faster (P < 0.0001) than those in sandy loam soils. Our results suggest that it may be possible to greatly reduce soil seed populations of Melaleuca in south Florida within 2 to 3 years after the seed source is eliminated.

Rapid response actions included containment under pvc tarps coupled with injection of liquid sodium hypochlorite. To assess the efficacy of these treatments, replicated sediment cores were removed from representative treated sites and transferred to grow-out facilities. Similar cores from uninfested (control) sediments were removed, inoculated with viable explants of C. taxifolia and placed in grow-out facilities. Results from two sampling periods (1 year, 2 years post-treatment) showed that no viable C. taxifolia emerged in cores, and that inoculated "control" sediments supported normal growth. Eelgrass (Zostera marina L.) seedlings emerged from native seed-banks in "treated" cores, which also supported growth of some invertebrates (annelid worms and hydroids). This study provided essential verification of C. taxifolia eradication efforts, and demonstrates the feasibility of incorporating quality control/quality assurance components in rapid response actions. Results of this study also suggest that seeds of eelgrass are viable for at least two years.

Some nations in the United States Affiliated Pacific Islands such as the Republic of the Marshll Islands (RMI), Federated States of Micronesia (FSM), and the Republic of Palau also face increasing economic pressure as funding from their respective Compacts of Free Association with the USA diminishes. Farming marine and freshwater aquaculture organisms has the potential to provide export products, alleviate social pressure on threatened food species, and provide import substitutes for the US Affiliated Pacific Islands. The economy mainly relies on foreign aid. Presently, there is emphasis on the development of marine resources, mainly marine aquaculture or mariculture, to meet future economic needs, become self-sufficient, and develop food security for its fast-growing population. Pollution-free water and biodiverse fauna of finfish and shellfish, of which several are endemic to the region, blesses all the US Affiliated Pacific Islands. Because the land area is minute compared to the vast ocean exclusive economic zones, it means that in all these nations the natural resources are primarily marine. The nation's abundant and extremely biodiverse coral reefs provide habitat for robust fish populations and other marine life that support subsistence and commercial fisheries. However due to over fishing and bad and destructive fishing practices, several species have become overexploited and need conservation. There is also a strong desire by the national governments to develop revenue-producing local industries based on available natural resources and to restock reefs where natural marine populations have declined. The national and local governments have also initiated marine protected areas (MPA) to revive the fisheries. In addition to this, there are several stock enhancement programs especially in shellfish like ornamental shellfish like trochus, black pearls, and giant clams being undertaken successfully to restock the depleted reefs and in the MPA. Preliminary results have shown that these stock enhancement programs have been successful mainly due to the community participation in these activities. The success and popularity of such measures have prompted the governments to look into the stock enhancement programs through sea ranching of hatchery-produced fish fingerlings of food finfishes like groupers, snapper, and other food fishes and several rare and endemic ornamental fish and shellfish species for food security, stock replenishment, and enhancement thus paving the way for future economic benefits and community self-sufficiency and self-reliance.

Enhancement of ant diversity by shrub invasion in south-western USA AN - 17619482; 6218368 AB - The conversion of desert grasslands to shrublands is a long-standing concern in the south-western United States, but the effects of this change on native animals defy generalization. Here, I consider evidence that shrub invasion and encroachment, particularly that of honey mesquite (Prosopis glandulosa), has led to increasing ecological dominance and diversity of ants in general, as well as increases in specific native taxa. The effects of shrub invasion on ants were measured at two scales: (1) between Chihuahuan Desert landscapes that vary slightly in temperature and strongly in the dominance of mesquite, and (2) across variation in mesquite density occurring within a generally mesquite-dominated landscape. Ant richness and numerical dominance was measured at pitfall traps over 2 years and baits were used to assess ecological dominance across different temperatures. The mesquite-dominated Jornada site harboured four times the number of ant foragers found at the relatively 'pristine' Sevilleta site, with several ecologically dominant taxa driving this pattern, especially Dorymyrmex bicolor. Species richness and ecological dominance were also greatest at the Jornada. Within the Jornada landscape, turnover in species composition was related to mesquite density, but local richness and abundance was unrelated to mesquite density. Coupled with the results of previous manipulative experiments and comparative studies, there is support for the notion that ant diversity is not negatively affected by shrub invasion but that several taxa prosper from it. The Jornada is uniquely saturated by dominant ant taxa, perhaps as a consequence of an overall high level of shrub availability that provides a reliable source of carbohydrate-rich plant exudates. This raises important questions about the relationship between environmental degradation, ecosystem productivity, and animal diversity.

The International Union for the Conservation of Nature and Natural Resources suggests a 12% threshold (area basis) for adequate protection of biological and genetic diversity of a plant community. However, thresholds based on area may protect only a small portion of the total diversity if the locations are chosen without regard to the variation within the community. The objectives of this study were to demonstrate methods to apply a coarse-filter approach for identifying gaps in the current reserve system of the Psuedotsuga menziesii (Douglas-fir) forest type group based on current climatic conditions and a global climate change scenario. Location: Western United States. Method: We used an ecological envelope approach that was based on seven bioclimatic factors, two topographic factors, and two edaphic factors. Multivariate factor analysis was then used to reduce the envelope to two dimensions. The relative density of habitat and protected areas were identified in each part of the envelope based on the current climate and potential future climate. We used this information to identify gaps in the reserve system. Results: Although the protected areas occurred in all parts of the envelope, most existed in colder and drier areas. This was true for both the current climate and potential future climate. Main conclusion: To protect more of the ecological envelope, future conservation efforts would be most effective in western Oregon, north-western Washington, and north-western California.

Cells AN - 17595411; 6432373 AB - Using synthetic substrates, an uncomplicated and sensitive procedure for the determination of extracellular aminopeptidase was developed. The studied enzyme produced by the tested plant material (calli, cell suspension culture and roots of Amsonia tabernaemontana Walt. seedlings) hydrolyzed the substrates beta - naphthylamides ( beta NA) and 4-(phenylazo) phenylamides (PAP-amide) of the amino acids to beta -naphthylamine and 4-(phenylazo) aniline, respectively, and amino acid. The beta -naphthylamides of the amino acids were applied for the identification of extracellular aminopeptidase, whereas the 4-(phenylazo) phenylamides of the amino acids were used for the determination of intra-and extracellular aminopeptidase activity. By simultaneous azocoupling of beta - naphthol with Fast Garnet GBC salt on agar plates a corresponding brown-red hardly water-soluble azo-dye was produced. The evaluation of dyed zones allowed the extracellular aminopeptidase activity to be assessed. No coloration of the agar medium was observed without inoculum, with heat-inactivated cells (10 min at 100 degree C) or in medium inoculated without substrate. On the agar plates with substrate and sterile Amsonia seedlings, changes in coloration were observed indicating a release of aminopeptidase from the roots during germination. The results show a 91.0 % intracellular and 9.0 % extracellular distribution of aminopeptidase activity, when a cell suspension culture of A. tabernaemontana Walt. as the plant material was used.

In this study, the hydraulic parameters for a silty clay soil in a large lysimeter were determined through inverse modeling of a fallow period with upward water flow from a shallow groundwater table. Parameter uniqueness was studied by simulating a hypothetical soil with known hydraulic properties under comparable conditions. Sensitivity analysis showed that the pressure head h(z,t), the volumetric water content [theta](z,t), and the cumulative bottom flux Q(t) were least sensitive to the residual volumetric water content [theta] sub(r) and the pore- connectivity parameter [lambda] in the van Genuchten-Mualem (VGM) model. Parameter response surfaces showed that least squares fitting with [theta](z,t) data is more likely to result in a unique hydraulic parameter set than least squares fitting with h(z,t) or Q(t) data. With only [theta](z,t) in the objective function, the least squares minimization algorithm was capable of finding the correct soil hydraulic parameters, provided that [theta] sub(r) and [lambda] were fixed and that multiple initial parameter estimates were used. The protocol that was developed for the hypothetical soil was subsequently applied to the actual groundwater table lysimeter. The soil hydraulic parameters for the lysimeter for two (x,y) locations were determined using [theta](z,t) data as measured by capacitance sensors. The variability in the optimized inverse of the air-entry value [alpha] and the saturated hydraulic conductivity K sub(s) in the VGM model was relatively high because of the high parameter correlation between these parameters. The optimized soil hydraulic properties can be used to study capillary rise from the groundwater table.

The objective of this study was to develop and characterize an intestine-specific cDNA library to examine the transcriptome of the bovine gut and identify expressed genes that influence ruminant nutrition and health. We describe BARC-8BOV, a normalized cDNA library developed from mRNA isolated from four distinct intestinal locations (duodenal, jejunal and ileal small intestine, colon) of Holstein dairy cattle resulting in 19,110 5'-EST deposited into the NCBI GenBank EST database. Assembly and clustering of these 19,110 clone sequences yielded 11,208 unique elements (3,419 contigs and 7,789 singletons) with an average length of 695 base pairs. Analysis strongly suggests normalization and tissue pooling were effective at increasing the discovery rate of new bovine sequence. A total of 1,123 sequence elements not previously identified in cattle, but with similarity to known genes in other animal species, were identified and shown to be involved in numerous critical biological processes. An additional 745 transcripts were not previously represented as EST in nucleotide or protein databases, and further analysis of these could lead to the identification of gut-specific transcript variants of known genes or potentially the discovery of novel bovine genes. Of the 11,208 assembled sequences, 11,034, or 98.4%, match sequences present in the bovine DNA trace archive at NCBI, and add to a bovine EST database previously lacking significant gut tissue representation. Ultimately, these data will also contribute in efforts to annotate the bovine genome.

This remains true despite the sequencing of the chicken genome. In view of this need, a scan of the chicken genome using 72 microsatellite markers was carried out on a meat-type x egg-type resource population measured for production and egg quality traits. Using a Bayesian analysis, potential QTL for a number of traits were identified on several chromosomes. Evidence of eight QTL regions associated with a total of eight traits (specific gravity, albumin height, Haugh score, shell shape, total number of eggs, final body weight, gain, and feed efficiency) was found. Two of these regions, one spanning the area of 263/287 cM on GAA01 and the other spanning the area of 23/28 cM on GAA02, were associated with multiple QTL.

Magnum 45) were harvested from 5 to 35 days postanthesis. The fruit of each age group were divided into exocarp, outer mesocarp, mid mesocarp, inner mesocarp, placenta, and seed. Each tissue was extracted and assayed for polygalacturonase-inhibiting protein (PGIP) activity against polygalacturonases (PGs) from three fungal pathogens of cantaloupe fruit. The PGIP activity of all tissues except placenta was high from the flower stage through the first week of fruit development but decreased markedly between 5 and 10 days postanthesis. PGIP activity against Phomopsis cucurbitae PG remained high and nearly constant in placental tissue throughout fruit development. However in this same tissue, PGIP activity against Fusarium solani PG decreased during fruit development to about 25% of its level in the 5-day-old fruit. This differential change in PGIP activity toward the two PGs suggests that different forms of the inhibitor are expressed between early and late stages of cantaloupe fruit development. The results also illustrate the importance of using multiple pathogen enzyme systems that can provide an opportunity for more accurate elucidation of mechanisms involved in the host-pathogen interaction.

Highly discriminating genetic markers for characterizing bacterial strains can help in clarifying the genetic relationships among strains. Under the auspices of the European Society of Clinical Microbiology and Infectious Diseases, the European Study Group for Epidemiological Markers (ESGEM) established guidelines for evaluating the performance of typing systems based of a number of criteria. Recently, HOOF- Print genotype analysis, a new method for typing Brucella abortus strains based on hypervariability at eight tandem repeat loci, was described. This paper evaluates the HOOF-Print assay by four of the criteria set out by the ESGEM: typeability, reproducibility, power of discrimination, and concordance with other typing methods. Results: The HOOF-Print Assay was evaluated with a test population composed of 97 unrelated field isolates and 6 common laboratory strains of B. abortus. Both typeability and reproducibility of the assay were excellent. Allele diversity and frequency varied widely among the eight loci, ranging from 1 to 13 alleles. The power of discrimination, measured by the Hunter-Gaston discrimination index (HGDI), varied by locus ranging from 0 to 0.89, where a maximal value of 1.0 indicates discrimination of all strains. The HGDI values calculated for subgroups sorted by biovar were similar to the values determined for the whole population. None of the individual loci achieved the recommended HGDI threshold of 0.95, but the HGDI of the composite profiles was 0.99 (93 unique genotypes from 97 field strains evaluated), well above the recommended threshold. By comparison, the HGDI value for biovar typing was 0.61 in a test population biased with disproportionate numbers of the less common biovars. Cluster analysis based on HOOF-Print genotypes assembled the strains into hierarchical groups with no apparent association with the time or location of strain isolation. Likewise, these hierarchical groups were not homogeneous with regard to biotype. In one extreme case, two field isolates with identical fingerprints were identified as different biovars by conventional methods. Conclusions: The main purpose of this study was to assess the ability of HOOF- Print genotyping to discriminate unrelated field strains of B. abortus, and whether the assay met established requirements for bacterial strain typing methods. The discriminatory power of the assay was remarkable, considering the genetic homogeneity found among species within the genus. The assay met or exceeded all of the recommended levels for the performance criteria of typeability, reproducibility, and power of discrimination, however some inconsistencies with conventional biovar typing were observed. Nevertheless, the results indicate that with cautious interpretation, multilocus genotyping of polymorphic tandem repeats by HOOF-Print analysis could be a valuable complement to routine epidemiological investigations into localized B. abortus outbreaks.

Feedstock costs can amount to a very significant fraction of the cost of the final biorefinery product. Thus, the reduction of the costs of feedstock production, harvest, collection, transportation, storage, and preprocessing can have a direct and positive effect on the overall viability of a given biorefinery. In addition, the feedstock and technology choices that are made for maintaining a sustainable biomass supply will have important implications not only for the biorefinery industry, but also for society as a whole. This session focused on feedstock supply, logistics, processing and composition, all of which are important elements of the feedstock supply chain.

To facilitate use of lignocellulosic material for ethanol, it will be necessary to determine cost-efficient pretreatments to enhance the conversion to fermentable sugars. The lignified residual products from ethanol production could also provide a value-added co-product for industrial feedstocks (e.g., nutritional antioxidants, ultraviolet absorbers, resins).

This paper describes a software application we have termed Windows .NET Distributed Basic Local Alignment Search Toolkit (W.ND-BLAST), which enhances the BLAST utility by improving usability, fault recovery, and scalability in a Windows desktop environment. Our goal was to develop an easy to use, fault tolerant, high-throughput BLAST solution that incorporates a comprehensive BLAST result viewer with curation and annotation functionality. Results: W.ND-BLAST is a comprehensive Windows-based software toolkit that targets researchers, including those with minimal computer skills, and provides the ability increase the performance of BLAST by distributing BLAST queries to any number of Windows based machines across local area networks (LAN). W.ND- BLAST provides intuitive Graphic User Interfaces (GUI) for BLAST database creation, BLAST execution, BLAST output evaluation and BLAST result exportation. This software also provides several layers of fault tolerance and fault recovery to prevent loss of data if nodes or master machines fail. This paper lays out the functionality of W.ND-BLAST. W.ND-BLAST displays close to 100% performance efficiency when distributing tasks to 12 remote computers of the same performance class. A high throughput BLAST job which took 662.68 minutes (11 hours) on one average machine was completed in 44.97 minutes when distributed to 17 nodes, which included lower performance class machines. Finally, there is a comprehensive high-throughput BLAST Output Viewer (BOV) and Annotation Engine components, which provides comprehensive exportation of BLAST hits to text files, annotated fasta files, tables, or association files. Conclusions: W.ND- BLAST provides an interactive tool that allows scientists to easily utilizing their available computing resources for high throughput and comprehensive sequence analyses. The install package for W.ND-BLAST is freely downloadable from http://liru.ars.usda.gov/mainbioinformatics.html. With registration the software is free, installation, networking, and usage instructions are provided as well as a support forum.

These protein subunits range in molecular weight from about 70K-90K and are made up of small N-terminal and C-terminal domains and a large central domain that consists of repeating sequences rich in glutamine, proline, and glycine. The cysteines involved in forming intra-and intermolecular disulfide bonds are found in, or close to, the N-and C-terminal domains. A model has been proposed in which the repeating sequence domain of the HMW-GS forms a rod-like beta -spiral with length near 50 nm and diameter near 2 nm. We have sought to examine this model by using noncontact atomic force microscopy (NCAFM) to image a hybrid HMW-GS in which the N-terminal domain of subunit Dy10 has replaced the N-terminal domain of subunit Dx5. This hybrid subunit, coded by a transgene overexpressed in transgenic wheat, has the unusual characteristic of forming, in vivo, not only polymeric forms, but also a monomer in which a single disulfide bond links the C-terminal domain to the N-terminal domain, replacing the two intermolecular disulfide bonds normally formed by the corresponding cysteine side chains. No such monomeric subunits have been observed in normal wheat lines, only polymeric forms. NCAFM of the native, unreduced 93K monomer showed fibrils of varying lengths but a length of about 110 nm was particularly noticeable whereas the reduced form showed rod-like structures with a length of about 300 nm or greater. The 110 nm fibrils may represent the length of the disulfide-linked monomer, in which case they would not be in accord with the beta -spiral model, but would favor a more extended conformation for the polypeptide chain, possibly polyproline II.

Aberrant gene expression is likely to account for much of the diminished viability and developmental abnormalities observed. In the present study, the expression of multiple genes in IVF and SCNT bovine blastocyst-stage embryos were evaluated and compared with in vivo-produced embryos. Eleven genes expressed at and following maternal-zygotic transcription transition were evaluated in individual blastocysts by real-time polymerase chain reaction following RNA amplification. A subset of those genes was also evaluated in individual IVF and SCNT eight-cell embryos. A fibroblast-specific gene, expressed by nuclear donor cells, was also evaluated in IVF and SCNT embryos. The observed gene expression pattern at the eight-cell stage was not different between IVF and SCNT embryos (P > 0.05). In vitro fertilisation and SCNT blastocyst expression was lower (P < 0.01) for all genes compared with their in vivo-produced counterparts, except for lactate dehydrogenase isoenzyme A (P < 0.001). The patterns of gene expression of the IVF and SCNT blastocysts were indistinguishable. Neither SCNT eight-cell nor blastocyst-stage embryos expressed the gene used as a fibroblast marker (collagen VI alpha 1). For the genes evaluated, the level of expression was influenced more by the environment than by the method used to produce the embryos. These results support the notion that if developmental differences observed in IVF-and SCNT-produced fetuses and neonates are the result of aberrant gene expression during the preimplantation stage, those differences in expression are subtle.

It typically consists of about 20% starch, 14% cellulose, and 30% hemicellulose in the form of arabinoxylan. Crude corn fiber (CCF) was fractionated into de-starched corn fiber (DSCF), corn fiber with cellulose (CFC) enriched, and corn fiber arabinoxylan (CFAX), and these fractions were evaluated as substrates for enzyme production by Trichoderma reesei. T. reesei QM9414 and Rut C-30 grew on CCF, DSCF, CFC, or CFAX and secreted a number of hydrolytic enzymes. The enzymes displayed synergism with commercial cellulases for corn fiber hydrolysis.

Mannitol can be produced through fermentation by microorganisms. Currently, a few Lactobacillus strains are used to develop an efficient process for mannitol bioproduction; most of the strains produce mannitol from fructose with other products. An approach toward improving this process would be to genetically engineer Lactobacillus strains to increase fructose-to-mannitol conversion with decreased production of other products. We cloned the gene mtlK encoding mannitol-2-dehydrogenase (EC 1.1.1.67) that catalyzes the conversion of fructose into mannitol from Lactobacillus brevis using genomic polymerase chain reaction. The mtlK clone contains 1328 bp of DNA sequence including a 1002-bp open reading frame that consisted of 333 amino acids with a predicted molecular mass of about 36 kDa. The functional mannitol-2-dehydrogenase was produced by overexpressing mtlK via pRSETa vector in Escherichia coli BL21pLysS on isopropyl- beta -d-thiogalactopyranoside induction. The fusion protein is able to catalyze the reduction of fructose to mannitol at pH 5.35. Similar rates of catalytic reduction were observed using either the NADH or NADPH as cofactor under in vitro assay conditions. Genetically engineered Lactobacillus plantarum TF103 carrying the mtlK gene of L. brevis indicated increased mannitol production from glucose. The evaluation of mixed sugar fermentation and mannitol production by this strain is in progress.

Cav. subsp. sativa (Mill.) Thell.] seeds at levels of 1.0% w/w or higher. Covering the pots with Petri dishes containing the soil-seedmeal mixture decreased germination of both species at the lowest application rate (0.5% w/w), suggesting that the some of the phytotoxins were volatile. CH sub(2)Cl sub(2), MeOH, and water extracts of the wetted seedmeal were bioassayed against wheat and sicklepod (Senna obtusifolia (L.) H. S. Irwin & Barneby) radicle elongation. Only the CH sub(2)Cl sub(2) extract was strongly inhibitory to both species. Fractionation of the CH sub(2)Cl sub(2) extract yielded two major phytotoxins, identified by gas chromatography-mass spectrometry and NMR as 2-propen-1-yl (allyl) isothiocyanate (AITC) and allyl thiocyanate (ATC), which constituted 80.9 and 18.8%, respectively, of the active fraction. When seeds of wheat, arugula and sicklepod were exposed to volatilized AITC and ATC, germination of all three species was completely inhibited by both compounds at concentrations of 5 ppm or less. In field studies, where seedmeal was applied at 0.50, 1.25, and 2.50 kg/m super(2) and tarped with black plastic mulch, all of the treatments significantly reduced dry weight of bioassay plants compared to the tarped control, with the highest seedmeal rate decreasing dry matter to less than 10% of the control 30 d after seedmeal application. Field pennycress seedmeal appears to offer excellent potential as a biofumigant for high-value horticultural crops for both conventional and organic growers.

The facility uses wheat straw as its feed source. Other highlights included the announcement by Dr. Guido Zacchi (Lund University, Sweden) that the ribbon will be cut this month at their new bioethanol pilot plant; the capacity will be 2 ton/day of feedstock (primarily softwood residue). Mr. Daniel Schell (National Renewable Energy Laboratory, CO, USA) detailed the production of high sugar streams from pretreating corn stover with dilute acid at the NREL pilot plant. Finally, Mr. David Gregg (University of British Columbia, Canada) and Dr. Henning Jorgensen (Royal Veterinary and Agricultural University, Denmark) also announced construction of new pilot plants for treatment of softwoods primarily by organosolv, and wheat straw possibly by alkali treatment, respectively. Several trends emerged from these presentations: Water balance: Dr. Zacchi and Mr. Schell both emphasized the importance of minimizing water usage. Dr. Zacchi's group has studied water recycle and Mr Schell has minimized water usage by increasing the solids contents in the pretreatment reactor to 30%wt. Dr. Zacchi in particular demonstrated the importance of water recycling by showing results from his group's sophisticated cost engineering model. Enzyme/Pretreatment Synergy: Mr. Brian Foody (logen Corp.) demonstrated that formulating cellulase preparations specifically for the pretreated biomass (e.g. wheat straw) increases hydrolysis efficiency. He also showed that increasing beta-glucosidase activity sufficiently makes SHF less costly than SSF. Dr. Liisa Viikari (VTT Biotechnology) demonstrated that xylanase activity can be an important component for increasing cellulose conversion yields. Dr Viikari also showed that laccase enzyme can aide in removing lignin. Operating Experience: Mr. Foody emphasized that their demonstration plant will be operated around the clock to better replicate the experience of trying to run a full scale plant.

Mating presumably occurs in these burrows but has never been directly observed in C. islagrande or any other thalassinidean. A variety of possible mating systems is suggested by those of other decapods, among which are examples of both internal and external sperm deposition, sperm competition among males, and male adaptations for paternity assurance. We used genetic markers to determine if clutches brooded by individual female ghost shrimp had been fertilized by multiple males. The two microsatellite loci we employed were sufficiently polymorphic to detect 95% of the occurrences of fertilization by two males. Among 40 ovigerous females collected from the Louisiana Isles Dernieres barrier island, eight (20%) carried egg masses for which more than two paternal alleles were detected, indicating fertilization by multiple males. In two cases of multiple paternity, alleles from one of the males were detected in only a portion of an egg mass. These observations suggest several, possibly novel characteristics of the mating system that can be further investigated.

Population indices are easier to obtain but are influenced by many unknowns and the relationships to actual population densities are usually unclear. Wildlife biologists, whether in the public or private sector, often find themselves in difficult situations where a resource manager or landowner wants good information, quickly, at low cost, and without clear objectives. In many situations, in addition to establishing clear objectives, a budget and timeframe, a biologist must understand and deal with the reality of many logistical concerns that will make the achievement of the objectives difficult or impossible. The situation is often complicated because the biology and ecology of the species of interest may be poorly understood in the specific setting and the species may be very rare or strongly influenced by current or past human activities. Methods to monitor a wildlife population may need to be tested or validated, extending the time and resources needed to complete the assigned task. In this paper, I discuss many of the challenges faced and the decisions to be made when a biologist is requested to provide useful, timely information on the status of a wildlife population.

Population indices can be efficient methods for monitoring populations when more labour-intensive density-estimation procedures are impractical or invalid to apply, and many monitoring objectives can be couched in an indexing framework. Indexing procedures obtain maximal utility if they exhibit key characteristics, including being practical to apply, being sensitive to changes or differences in the target species' population, having an inherent variance formula and allowing for precision in index values, and relying on as few assumptions as possible. Additional useful characteristics include being able simultaneously to monitor multiple animal species and to describe spatial characteristics of the species monitored. Here, a paradigm is presented that promotes the characteristics that make indices most useful. Observations are made at stations located throughout the area of interest. Stations can take many forms, depending on the observations, and range from points for visual counts to tracking plots to chew cards, and many others. A wide variety of observation methods for many animal species can fit into this format. Observations are made at each station on multiple occasions for each indexing session. Geographic location data for each station are encouraged to be collected. No assumptions of independence are made among stations, nor among observation occasions. Measurements made at each station are required to be continuous or unboundedly discrete. The formula for a general index to describe population levels is presented and its variance formula is derived. Issues relevant to the application of this methodology, and indices in general, are discussed.

Pelletized samples of turkey litter and cake were converted to granular activated carbons (GACs) by steam activation. Water flow rate and activation time were changed to produce a range of activation conditions. The GACs were characterized for select physical (yield, surface area, bulk density, attrition), chemical (pH, surface charge) and adsorptive properties (copper ion uptake). Carbon physical and adsorptive properties were dependent on activation time and quantity of steam used as activant. Yields varied from 23% to 37%, surface area varied from 248 to 472 m super(2)/g and copper ion adsorption varied from 0.72 to 1.86 mmol Cu super(2+)/g carbon. Copper ion adsorption greatly exceeded the values for two commercial GACs. GACs from turkey litter and cake show considerable potential to remove metal ions from water.

Embryogenic callus was maintained for 5 yr on either Schenk and Hildebrandt's basal salts medium (SH) supplemented with 13.6 mu M 2,4-dichlorophenoxyacetic acid (2,4-D) or Murashige and Skoog's basal salts medium (MS) supplemented with 18.1 mu M dicamba and 0.46 mu M kinetin. Maturation of embryos was three times higher using callus maintained on the SH medium supplemented with 2,4-D while conversion of cotyledonary-stage embryos to plants was significantly higher (10 times) using callus that had been maintained on MS medium with dicamba and kinetin. Maximum maturation (13.5%) and conversion (15.2%) occurred when callus was cultured on MS maturation medium without hormones. Cotyledonary-stage embryos cultured on MS conversion medium supplemented with abscisic acid (5-20 mu M) produced plants that survived at a significantly higher rate (two times) in the greenhouse than when embryos were cultured without abscisic acid. The highest rate of plant regeneration occurred when embryogenic callus of 'Kardinal' was maintained on MS medium supplemented with dicamba and kinetin, maturation of embryos occurred on MS maturation medium without hormones, and conversion of cotyledonary-stage embryos occurred on MS conversion medium supplemented with abscisic acid.

Although the soil moisture neutron probe has served this need well, it cannot be used unattended. Newer methods, which respond to the electrical properties of soils, typically allow data logging and unattended operation, but with uncertain precision, accuracy, and volume of sensitivity. In laboratory columns of three soils, we calibrated a conventional time domain reflectometry (TDR) system for use as a reference system for a companion study of water content sensors that are used in access tubes. Measurements were made before, during, and after wetting to saturation in triplicate repacked columns of three soils: (i) a silty clay loam (30% clay, 53% silt), (ii) a clay (48% clay, 39% silt), and (iii) a calcic clay loam (35% clay, 40% silt) containing 50% CaCO sub(3). Each 75-cm-deep, 55-cm-diameter column was weighed continuously to 50-g precision on a platform scale. Conventional TDR measurements of water content and thermocouple measurements of temperature were made at eight depths in each column every 30 min. Accuracy of the TDR system was judged by the root mean squared difference (RMSD) between column mean water contents determined by mass balance and those determined using the Topp equation as a standard calibration. Smaller values of the RMSD metric indicated more accurate standard calibration. Although the TDR system exhibited RMSD <0.03 m super(3) m super(-3) using the Topp equation, there were differences in accuracy between the three soils, and there was some temperature dependency at the saturated end, although not at the dry end. This paralleled the temperature dependency of the soil bulk electrical conductivity (BEC). Incorporation of bulk electrical conductivity and effective frequency of the TDR measurement into the calibration model reduced the calibration RMSE to <0.01 m super(3) m super(-3) and practically eliminated temperature effects. Because the temperature effects on the TDR measurement are embedded in the BEC and effective frequency, a measurement of temperature is not needed to apply the calibration to these soils.

Previous research indicates that ponded infiltration estimates are influenced by the volume or cross-sectional area of the measurement. Our study compared quasi-steady infiltration measurements made using 20-, 30-, and 45-cm-diameter cylinders driven 25 cm deep into 56 field plots under diverse agricultural management practices. Mean infiltration rate increased from 50, to 81, to 95 mm h super(-1) as diameter increased. Standard deviation and range also increased with diameter. All three diameters produced lognormal data distributions. These results indicate that increasing the sample area is not equivalent to pooling of many smaller samples, which would have produced the same mean but with a lower variance. Follow-up experiments with a double-ring configuration or a divider placed in the center of a 45-cm cylinder demonstrated that adding vertical barriers reduced infiltration even when the total infiltration area was unchanged. A pulse of dye introduced 10 min before removing the ponded water showed an extensive network of dyed flow pathways in all but the slowest infiltration situations. The pathways were not associated with visible macropores. Careful consideration should be given to the dimensions of samples used to estimate saturated and possibly unsaturated flow from infiltration experiments.

The tremendous interest in vadose zone monitoring reflects the intense societal interest in understanding our environment, the increasing comprehension of scale-dependence of vadose zone properties and processes, and the rapid changes occurring in sensing methods. In this article, we present an overview of the papers, many of which detail methods that rely on soil electromagnetic (EM) responses, including time domain reflectometry (TDR), ground penetrating radar (GPR), and capacitance methods. The papers also indicate key aspects of sensor performance requiring improvement through further sensor development.

The derivative, YRNC10-gfp, was highly GFP fluorescent, retained the gfp-km marker in the absence of kanamycin selection, and exhibited in vitro growth kinetics similar to those of the wild type strain. YRNC10-gfp colonized and caused mortality in immersion and intraperitoneally challenged rainbow trout Oncorhynchus mykiss, although it was modestly attenuated compared to the wild type strain. The distribution and location of YRNC10-gfp in infected fish was visualized by epifluorescence microscopy. Abundant extracellular bacteria and a small number of intracellular bacteria were observed in the kidney, spleen and peripheral blood. To determine the percentage of trout cells containing intracellular bacteria, GFP fluorescence was measured by flow cytometry. A small population of GFP positive leukocytes was detected in peripheral blood (1.6%), spleen (1.1%) and anterior kidney (0.4%) tissues. In summary, this is the first report of the construction of a virulent, GFP-tagged Y. ruckeri, which may be a useful model for detecting and imaging the interactions between an aquatic pathogen and the natural salmonid host.

In most cases, critical issues related to sensor calibration and accuracy have received little independent study. We investigated the performance of the Hydra Probe soil water sensor with the following objectives: (i) quantify the inter-sensor variability, (ii) evaluate the applicability of data from two commonly used calibration methods, and (iii) develop and test two multi-soil calibration equations, one general, "default" calibration equation and a second calibration that incorporates the effects of soil properties. The largest deviation in the real component of the relative dielectric permittivity determined with the Hydra Probe using 30 sensors in ethanol corresponded to a water content deviation of about 0.012 m super(3)m super(-3), indicating that a single calibration could be generally applied. In layered (wet and dry) media, [epsilon] sub(r) super(') determined with the Hydra Probe was different from that in uniform media with the same water content. In uniform media, [theta] was a linear function of [surd][epsilon] sub(r) super('). We used this functional relationship to describe individual soil calibrations and the multi- soil calibrations. Individual soil calibrations varied independently of clay content but were correlated with dielectric loss. When applied to the 19-soil test data set, the general calibration outperformed manufacturer-supplied calibrations. The average [theta] difference, evaluated between [epsilon] sub(r) super(') = 4 and [epsilon] sub(r) super(') = 36, was 0.019 m super(3)m super(-3) for the general equation and 0.013 m super(3)m super(-3) for the loss-corrected equation.

Trends in research include the increased use of biorational screening processes to identify microorganisms with potential for biocontrol, increased testing under semicommercial and commercial production conditions, increased emphasis on combining biocontrol strains with each other and with other control methods, integrating biocontrol into an overall system.

This study evaluated the effect of slope on infiltration and surface runoff from a variable-slope box under artificial rainfall simulation. The variableslope box consisted of 0.25 m deep Captina silt loam soil (fine-silty, siliceous, active, mesic Typic Fragiudult) seeded to tall fescue (Festuca arundinacea Schreb.); rainfall simulations were conducted on 11 slopes (0, 1, 2, 4, 6, 8, 10, 15, 20, 25, and 28%). The rainfall simulations were about 20-min long at 5-cm hr-1 because initial results showed that runoff occurred after 5-min, and we wanted about 15- min of continuous runoff for this investigation. The variable slope box demonstrated the effect of slope on infiltration rate and surface runoff production, where surface runoff volume increased with the natural logarithm of slope (%slope plus 0.1). However, the effect of slope was almost precluded by variability in surface runoff production probably resulting from variation in the antecedent soil moisture of the variable-slope box. The variations in antecedent moisture were likely related to the change in ambient air temperature occurring with time and natural rainfall during late fall. It may be that slope of the infiltrating surface has the greatest effect on surface runoff production when the soil is closer to saturation. The effect of slope on infiltration and surface runoff production needs additional investigation where antecedent soil moisture conditions would be measured spatially within the variable-slope box.

These [lambda] values relate and can scale cumulative infiltration and water contents during redistribution across dissimilar textural classes under different rainfall and initial conditions. The objectives of this work were to explore if relationships exist between evaporation (E) and transpiration (T) and [lambda] across different soil types and if these relationships can be used to scale E and T among these soils. The Root Zone Water Quality Model generated evaporation under four potential rates and transpiration under one potential rate with a goosegrass [Eleusine indica (L.) Gaertn.] in 11 soil textural classes under near-saturated initial conditions. Stage I cumulative evaporation or transpiration that occurs when the soil is sufficiently wet to meet the potential rates had a quadratic relationship with [lambda]. However, both Stage II cumulative evaporation and transpiration were cubic functions of [lambda] with time-dependent coefficients. It is shown that these relationships can be used to estimate both Stage I and II cumulative evaporation and transpiration across unknown soils, especially when data for one dominant reference soil type is known. The methods developed for estimating cumulative evaporation were applied and compared with experimental results of three initially saturated soils under constant evaporation with good results. These results for simple homogeneous soils should be useful in quantifying spatial variability of evaporation and transpiration in the field under similar conditions, and could form the basis for further research of more complex conditions.

The objective of this study was to assess the influence of vegetation type, climate, topography, and management history on the distribution and abundance of eight selected nonnative plant taxa in forests in western Oregon. These eight taxa were selected as being reliably detected by a multi-resource inventory of 1127 systematically-placed plots on nonfederal forest lands from 1995 to 1997 by the USFS Forest Inventory and Analysis (FIA) program. One or more of the eight nonnative taxa studied were found on 20% of the sampled subplots in the study area, but relatively few stands were dominated by them. Overall abundance of nonnative taxa was likely much greater, because few composites and graminoids were identified to species in this general-purpose inventory. Distribution of most taxa was more closely associated with low density of overstory trees than with climate. Nonnative taxa were significantly more abundant in stands that had been recently clearcut or thinned than in stands that had not. Frequencies of several taxa decreased with elevation, which may reflect proximity to source populations and intensive land use rather than any climatic constraints. Although the greatest potential for displacement of native forest species appears to be in early-successional communities, the potential for spread of some shade-tolerant evergreen shrubs also seems high.

Dextrans with the molecular mass of 19.6 kDa, 87 kDa, 150 kDa, 500 kDa, and 2000 kDa were attached to beta -lactoglobulin via the Maillard reaction. The conjugates were then purfied and evaluated as emulsifiers under neutral conditions. The ability to stabilize emulsions was determined by monitoring oil droplet size over time. Adsorption of the conjugates to the droplet surface was characterized by determining the protein surface load. The results show that increasing polysaccharide size increases emulsion stability up to 150 kDa before leveling off. Conversely, surface protein density remains constant until 150 kDa before decreasing with polysaccharide size. A model is presented to interpret the results.

Toward this end, 11 profiles of suspended-sediment concentration and fluid velocity were collected in supercritical conditions over low-relief antidunes in a recirculating laboratory flume. It was found that velocity profiles agreed well with the law of the wall, and that turbulence intensities were similar to those in clear-water flows. The classic Rouse equation was found to under-predict concentration values in the upper 60-80% of the flow depth and a slightly modified version was proposed and successfully tested against experimental data from the present study and others.

As the water passes through the off-line settling basins, the solids settle out and the excess water is discharged to surface water. Since the basins are not frequently emptied, the organic solids mineralize and nutrients flow out of the basins with the surface water discharge. A system was tested to remove solids from settling basins frequently and treat by mesophilic composting. Two carbon (C) sources (wheat straw or oak sawdust) were evaluated. Manure was applied to beds of carbon sources at a rate of about 1cm of arctic char manure (8% solids) every 10 days using a vacuum tank spreader modified for side discharge over the plots. The open and porous structure of wheat straw resulted in several advantages over the oak sawdust; there was not runoff during application even during freezing winter temperatures when the oak sawdust compost was frozen solid, aerobic conditions were maintained with lower amounts of C, and decomposition rates were higher resulting in less time needed to reach stability (about 90d vs. 140d). Inorganic nitrogen (N) increased as the organic matter decomposed with either C source. Mineralization and nitrification rates were higher with wheat straw. Water-extractable P decreased as the organic matter from both C sources decomposed. Land requirements are about 0.001 ha to compost the manure for each 1 Mg Arctic char produced annually, but could be significantly higher for the wheat straw since experimental loading rates were limited by the reduced capacity of the oak sawdust compost. A layered mesophilic compost system may be a viable manure management system to store and treat manure and replace long-term storage in off-line settling basins for fish farmers. In this system, solids would continue to be settled in the off-line settling basins but pumped onto straw nearby for storage and stabilization on land thereby minimizing discharge of nutrients to surface water.

Randomly selected cDNA clones were partially sequenced to generate a total of 1825 ESTs, 769 from the C34-24 cDNA library and 1056 from the A13 cDNA library, in which 536 and 769 unique ESTs were identified, respectively. Results of BLASTx search showed that 52.8% of the ESTs from leaf tissue and 78.6% of the ESTs from the pod tissue have homology to genes of known function. Approximately 27.3 and 22.1% of ESTs matching homologous sequences in dbEST of GenBank on the basis of BLASTn algorithm have unknown functions. The ESTs were queried against MIPS functional catalog criteria and sorted according to putative function into 15 categories. A total of 1345 ESTs have been released to GenBank. Four hundred unigenes have been selected from these ESTs and arrayed on glass slides for gene expression analysis, and 44 EST-derived simple sequence repeat (SSR) markers have been characterized for cultivated peanut, in which over 20% of the SSRs produced polymorphic markers among 24 cultivated peanut genotypes. This is the first report of ESTs in cultivated peanut, and further characterization of resistance and stress genes may explain mechanisms functioning in these two peanut lines.

It is commonly measured with sensors, but these provide an indirect measurement and there is variability between different makes of sensors. Consequently, there is no standard for surface wetness measurement. The objective of this study was to derive and validate a physically based theoretical definition of surface wetness for both drops and films drying under controlled conditions. The validation compared observations of surface wetness with theoretical simulations for a range of factors: atmospheric variables including temperature, humidity, net radiation and wind speed; plant physical properties including surface wettability, leaf width and thickness; and initial water distribution including drop volume and film thickness. The drying of drops and films was studied in a wind tunnel and a laboratory setting. Surface wetness duration was most sensitive to initial drop volume or film depth, relative humidity and surface wettability in the case of water distributed as drops. Surface wetness duration was relatively insensitive to other atmospheric variables. Water distribution whether drop or film, made a four-fold difference in evaporation rate compared to leaf width, which was unimportant for leaves larger than 3 cm. The observations were compared to the theoretical estimations using a surface energy balance model. The surface energy balance model is based on a combination equation and a generic transfer coefficient. The transfer coefficient is dependent upon whether the water is present as drop or film and is assumed to be independent of leaf width or drop dimension. Considerations of drop geometry are ignored, although the initial wet area must be known. The theoretical understanding of drop and film drying under controlled conditions could potentially be useful in a field scale model of surface wetness. Since all the factors that influence surface wetness can be explicitly defined, such a field scale model has potential to be used as a theoretical standard for surface wetness estimation. Additional research is required to test this model under controlled conditions of condensation.

Six sub-watersheds (similiar in begetation, soil type, stream size, and disturbance history) were located within the Conasauga River Watershed; four of the sites were burned in March 2001, and two sites were designated as controls. Within each site, vegetation was measured in layers: the overstory layer(trees 5.0-cm DBH), the midstory layer (woody stems < 5.0-cm DBH and 0.5 m height), and the ground flora layer (woody stems < 0.5-m height and all herbaceous species). All plots were sampled before the prescribed burn (Sept. 2000) and after the burn in July of 2001 and 2002. Consistent with the goals of the land managers, all the prescribed fires resulted in low-to-moderate intensity and low severity fires. However, we found no significant change in the overstory, midstory, or ground flora species diversity after burning. We found no regeneration of P. echinata seedlings after the prescribed fire. Although fire reduced basal area of woody species in the midstory, prolific sprouting from hardwoods resulted in higher density of fire-sensitive hardwoods such as Acer rubrum, Oxydendrum arboretum and Nyssa sylvatica. density of Pinus strobus, an undesirable species, was reduced by 20% and its basal area was redued by 50% after the burn. Overstory morality occurred in small size class hardwoods as a result of the fire, but most of the mortality occurred in P. echinata and P. virginiana Miller due to infestation with pine bark beetles. The prescribed fires were not of sufficient intensity to: reduce overstory basal area, prepare a seedbed for successful pine germination, affect diversity of any of the vegetation layers, or promote A. gyrans and S. scoparium recruitment. Thus, additional fire treatments or a combination of fire and thinning treatments will be necessary to restore these ecosystems to P. echinata/mixed-oak/bluestem grass community types.

The effects of forest management and environment on these secondary patch types are often poorly understood. For example, do early-to-mid successional minor patch types become more expansive as late successional forest types are fragmented or do they also become more fragmented in managed landscapes? We evaluated the dynamics of early-to-mid successional hardwood patches in a conifer-dominated landscape in relation to environment and land ownership in the central Coast Range of Oregon, USA, from the time of early logging to the present-day using scanned and georeferenced aerial photographs and a GIS. Hardwood patches declined in size, number, total area, and within-patch cover-type heterogeneity, and became more irregular in shape. Patch turnover and fragmentation was high, with most patches present at the historical date disappearing by the present-day. Land ownership was important to hardwood patch dynamics: hardwoods declined on lands owned by the USDA Forest Service, increased on non-industrial private lands, and were at similar levels at both dates on private forest industry lands. Patch locations became more restricted to near-stream, lower elevation areas where hardwoods are competitive. The relatively extensive distribution of hardwood patches at the historical date probably resulted from earlier fire, selective logging, and grazing. In recent decades, forest management that includes fire suppression and intensive management, and ecological constraints have resulted in a landscape in which early-to-mid successional hardwood patches have been reduced in size, fragmented, and restricted to particular locales.

Although these methods have historically constituted the majority of tree mortality summarizations, they have had limited use in assessing mortality trends and dynamics. This study proposed a novel method of applying survival analysis for the purpose of analyzing tree mortality in forest inventories. Individual tree size and growth increments were used to estimate survival and hazard functions for a forest inventory for the state of Minnesota. These estimates provided regional mortality and variance estimates by diameter at breast height (DBH) and diameter growth classes ( Delta DBH) between successive inventories. Comparisons of survival/hazard curves for various tree populations and tests of effects of covariates on individual survival curves were conducted allowing for mortality hypothesis testing across user-defined tree populations (i.e., species, location, stand conditions, and damage agents). Survival analysis techniques, facilitated by the variables of DBH and Delta DBH, may provide foresters with the ability to test tree mortality hypotheses and summarize regional tree mortality trends.

Changes in species diversity, structural diversity, and the abundance of non-native species are common national concerns, and are part of the international criteria for assessing sustainability of forestry practices. The vegetation indicator for the national Forest Inventory and Analysis (FIA) Program, USA, was designed to assess these issues. The objectives of this study were to: (1) assess the repeatability and practicality of the vegetation field techniques using independent measurements of 48 plots by two botanists and (2) examine the interpretation of forest health indicators from 2 years of data collected on 110 plots in the state of Oregon. Plant identification was similar for both botanists, with 80% of all plant species on the plot being identified to species, and another 14% identified to the genus level; the greatest problems were in dry forest types where plants had senesced by July. Agreement among botanists for species identification was 71% at the subplot level and 67% at the quadrat level, with many differences caused by plants being identified as closely related species, usually in the same genus. As a result, agreement between botanists on species richness and the abundance of non-native species was high, with correlation coefficients of 0.94 and 0.98, respectively. Quadrats detected only 20% of the species found from the subplot search, on average. Although botanists differed in their speed, 22% of subplot searches were completed within 15 min and 71% were completed within 30 min. Dramatic differences in patterns of plant diversity were found across the ecological regions of Oregon, with high plot richness and the highest species turnover among plots found in the Blue Mountains. Abundance of non-native species varied from 15% of the species in juniper (Juniperus occidentalis Hook.) stands to 1% in high-elevation conifer stands. The proportion of cover made up of non-native species was highest in juniper and Ponderosa pine (Pinus ponderosa P. & C. Lawson) forest types. Numbers of non-native species on a plot increased with the number of native species, but the relationship was weak (R super(2) = 0.09). Results suggest that the vegetation indicator provides a robust and valuable tool for assessing forest health.

Research was undertaken to investigate the use of bioluminescent ATP determination and a firefly luciferase assay to estimate the initial population of aerobic mesophilic bacteria on fresh-cut melons immediately after preparation and during storage at 5 or 15 degree C for up to 12 days. Populations of aerobic mesophilic bacteria on fresh-cut cantaloupe prepared immediately from unsanitized whole melons averaged 3.42 log CFU/g, corresponding to an ATP value of 5.40 log fg/g. Populations for fresh-cut honeydew prepared from unsanitized whole melon averaged 1.97 log CFU/g, corresponding an ATP value of 3.94 log fg/g. Fresh-cut pieces prepared from cantaloupe or honeydew melons sanitized with either chlorine (200 ppm free chlorine) or hydrogen peroxide (2.5%) had similar ATP values: 3.1 log fg/g (corresponding to bacterial counts 1.7 log CFU/g) for cantaloupes and 2.6 log fg/g (corresponding to bacterial counts of 0.48 CFU/g) for fresh-cut honeydew. Positive linear correlations for ATP concentrations and microbial populations were found for fresh-cut cantaloupe (R super(2) = 0.99) and honeydew R super(2) = 0.95) during storage at 5 degree C for up to 12 days. ATP values in fresh-cut melons inoculated with either aerobic mesophilic bacteria or yeast and mold were significantly higher (P < 0.05) than control values and parallel total plate counts on plate count agar. Results of this study indicate that the bioluminescent ATP assay can be used to monitor total microbial populations on fresh-cut melon after preparation and during storage for quality control purposes to establish specific sell-by or consume-by dates.

Oviposition substrates, used as baits in these traps, were tested against Culex under laboratory and field conditions. In the laboratory all substrates tested as 1% and 10% dilutions in 2-choice bioassays against female Cx. quinquefasciatus were significantly more effective than well water controls in eliciting oviposition. Strongest responses were to dilutions of dairy effluent, followed by larval water and infusions of alfalfa hay, alfalfa pellets, Bermuda hay, oak leaves, and Typha leaves, with lowest responses to cow manure infusion. In the field, few significant differences in collections were obtained between traps baited with different infusions. Significantly more Cx. quinquefasciatus and Cx. nigripalpus were collected in traps baited with cow manure infusion (highest) compared to alfalfa hay infusion (lowest). Responses of Cx. quinquefasciatus to dairy effluent and infusions of Bermuda hay, oak leaves, and Typha leaves were not significantly different from either cow manure infusion or alfalfa hay infusion. Responses of Cx. nigripalpus were highest to cow manure infusion and equally low to infusions of alfalfa hay and Typha leaves; moderate responses were observed to dairy effluent and infusions of Bermuda hay and oak leaves. Gravid females comprised 66.7- 81.9% of the collections for each infusion type, with no significant difference among infusions in the proportion of gravid females collected.

(Coleoptera: Coccinellidae), in the mid-1980s. In this study, coccinellids were sampled within field-crop and grass habitats in eastern South Dakota from 1990 to 1995 to survey for various coccinellid species and to determine any effects of habitat management on abundance. Field crops (maize, wheat-alfalfa intercrop, and alfalfa) were subjected to high, intermediate, or low crop-management intensity (CMI), and grass habitats were managed for stands of warm season, cool season, or mixed species. A total of 1,306 adult and 155 larval coccinellids were collected. Four native species (Coleomegilla maculate (DeGeer), Hippodamia convergens Guerin-Meneville, Hippodamia parenthesis (Say), and Hippodamia tredecimpunctata tibialis (Say)) and C. septempunctata comprised over 96 percent of all coccinellids collected. Of declining species, four Coccinella transversoguttata richardsoni Brown were collected from alfalfa, but Coccinella novemnotata Herbst and Adalia bipunctata (L.) were not found during the study. Coccinellid abundance was seldom affected by CMI. Coccinellids were more abundant in wheat-alfalfa in 1995 under high than low CMI. Coccinellid abundance in maize and alfalfa did not differ with CMI. A prey species, Empoasca fabae (Harris) (Heteroptera: Auchenorryncha: Cicadellidae), was more abundant in alfalfa in 1995 under high and intermediate than under low CMI. Coccinellid abundance was not correlated with that of E. fabae in 1995, and showed inconsistent association with E. fabae during the study. In grass, adult coccinellids (total across species), adult H. tredecimpunctata tibialis, and aphids were more abundant in warm-season grasses than in cool-season or mixed grass stands in one of three years. Our results provide further evidence that C. septempunctata has become relatively abundant in eastern South Dakota, whereas C. transversoguttata richardsoni, C. novemnotata, and A. bipunctata have become rare or absent.

Our objectives were to: 1) evaluate the potential for establishing genotypes of poplar and willow on soils heavily contaminated with petroleum hydrocarbons and 2) identify promising genotypes for potential use in future systems. We evaluated height, diameter, and volume after first year budset by testing 20 poplar clones and two willow clones. Unrooted cuttings, 20 cm long, were planted in randomized complete blocks at 0.91- x 0.91-m spacing at Gary, IN, USA (41.5 degree N, 87.3 degree W). Four commercial poplar clones (NM6, DN5, DN34, and DN182) were planted as 20- and 60-cm cuttings. Sixty-cm cuttings exhibited greater height and diameter than 20-cm cuttings; however, we recommend continued use and testing of different combinations of genotype and cutting length. We identified promising genotypes for potential use in future systems and we recommend allocating the majority of resources into commercial poplar clones, given their generalist growth performance. However, further utilization and selection of experimental clones is needed. Specific clones rather than genomic groups should be selected based on the geographic location and soil conditions of the site.

Drainage water is known to increase the quantity of offsite flows and to contain soluble nutrients, agrochemicals, and salts that can negatively impact the receiving water body. Environmental and ecological impacts may result from these pollutants such as increased flooding, lake eutrophication, development of hypoxic zones, loss of habitat, reproductive failures in wildlife species, and contamination of drinking water supplies. Drainage management has the potential to reduce these offsite effects. A replicated field plot experiment was conducted to examine the hydrology, water quality, and crop yield impacts of drainage management practices including controlled drainage, uncontrolled drainage, and subirrigation drainage on Hoytville silty clay soil in Ohio. Annual subsurface drainage volume was greatest with subirrigation drainage and least with controlled drainage. The concentration of nitrate in the subsurface drainage water was greatest with uncontrolled drainage and least with subirrigation drainage. Annual load of nitrate in the subsurface drainage water was least with controlled drainage and greatest with uncontrolled drainage. The concentration of nitrate in the shallow ground water was least beneath subirrigation drainage and greatest beneath uncontrolled drainage.

The DRB, Bradyrhizobium japonicum isolate GD3, previously isolated as a DRB producing high concentrations of indole-3-acetic acid (IAA), and Pseudomonas putida isolate GD4, were compared with a plant growth promoting rhizobacterium (PGPR), Bacillus megaterium isolate GP4. Scanning electron microscopy revealed that the colonization of isolates GP4 and GD4 were consistently distributed on the surface of roots; however, isolate GD3 was deeply localized into surface furrows of roots. Transmission electron microscopy showed considerable alterations of root cells including vesiculation, partial cell wall degradation, and cytoplasm disorganization. The average population density of isolate GD4 on the root surface was about 10 and 100 times greater than GP4 and GD3, respectively. Root elongation of seedlings inoculated with isolates GD3 and GD4 after 7 d of growth was significantly inhibited by ca. 26% and 90%, respectively, compared to the control. This study showed that inhibition of morningglory root growth by isolate GD3 might be related to production of high concentrations of IAA although other phytotoxins likely contributed to inhibiting root elongation of morningglory inoculated with isolate GD4. Rhizobacteria able to suppress morningglory growth may be effective as biological control agents to supplement herbicide weed management in crops where morningglory is difficult to control.

The greatest impact on the richness of species diversity was caused by the loss of connectivity with the Danube river system. A continuous type of macrophyte distribution prevailed in the canalised bed. Timing of flood disturbances and historical genesis of the habitats have reflected in proportion of growth forms. The submersed hydrophytes dominated in the most recently created aquatic habitat, alternating with the local patches of acro-pleustophytes. The higher presence of floating leaf rhizophytes was recorded in more advanced successive stages. To retard the process of succession towards the terrestrial ecosystem, future management should consider the restoration of flow conditions in analysed habitats.

The objective of this study was to simulate the first order sensitivity of water resources, soil erosion, and wheat production to assumed climate changes in the region near El Reno, Oklahoma using the Water Erosion Prediction Project (WEPP) model and a climate generator (CLIGEN). Monthly forecasts for the periods of 1950-1999 and 2070-2099 for the region, projected by the UK Hadley Centre's third generation general circulation model (HadCM3), were used. Three emissions scenarios (A2a, B2a, and GGa1) were selected. The WEPP model was run for each scenario in three tillage systems. Projected changes in monthly mean and variance between the two periods at the HadCM3 grid scale were downscaled to daily climate data using CLIGEN. Spatial downscaling from the HadCM3 grid scale to the target location was not intended, and therefore the responses reported in this paper reflect a first-order regional sensitivity. The HadCM3 predicted a general decrease in precipitation in the study area over the century. As a result of precipitation reduction, predicted plant evaporation, soil evaporation, and the long-term soil water reserve were reduced in all three climate change scenarios. However, the decreases in rainfall did not necessarily result in reductions in wheat yields, largely because most decreases were predicted in the non-growing season. About a 1% decrease in wheat yields were predicted for A2a and B2a, while a 6% increase was predicted for GGa1. Regarding soil erosion, the results indicate a possibility for increasing erosion despite the predicted decreases in annual precipitation due to the predicted increases in precipitation variability.

Among herbicides studied, dissociable herbicides (MCPA and 2,4-D-DMA) were the least sorbed, whereas nonionic herbicides were the most sorbed (acetochlor < chlorotoluron < trifluralin). The distribution coefficient values K sub(D) and equilibrium sorbed amounts positively correlated with soil organic carbon content for all herbicides except MCPA. Moreover, all herbicides except MCPA were the most sorbed in the Vertisoil (SA) with relatively high content of expanding clay minerals in proportion to organic carbon content. Organic carbon - water distribution coefficient values K sub(oc) for each herbicide showed a smaller variation among soils used except the SA soil than distribution coefficients K sub(D). To estimate potential risk of groundwater contamination by herbicides investigated, measured K sub(OC) and treshold GUS values (Groundwater Ubiquity Score) were used to calculate half-lives t sub( one half ) that would rank herbicides as potentially hazardous and non-hazardous. Comparison of calculated t sub( one half ) values to published was found that atrazine and MCPA could be considered hazardous herbicides, trifluralin non-hazardous herbicide and acetochlor, 2,4-D and chlorotoluron could be hazardous or non-hazardous, depending on soil type. Presented analysis was also in line with risk assessment of groundwater contamination according to EPA (Environmental Protection Agency) criterion.

This protective effect was manifested by hydroponical growth of maize in Knop's nutrition medium contaminated by copper, mercury or cadmium chlorides. The use of 6.7 g zeolitic tuff per L of Knop's nutrition medium polluted with 30 mu mol of Cu, Cd or Hg resulted in almost 100% restoration of plant growth, as far as the plant size and dry matter (DM) are concerned. It was found that the heavy metals are absorbed and disposed mainly by maize roots. However, a considerable amount of cadmium has been distributed into the plant's shoots and leaves (140 mg Cd per kg DM of each). This feature of the maize could be utilized for phytoremediation of Cd-contaminated soils after the verification of this effect at long-term experiments.

Tension infiltrometer experiments are extremely useful to investigate infiltration into fracture networks, but are difficult to perform using commercially available equipment developed mostly for soils. Our objective was to develop a tension infiltrometer suited for accurate measurements of infiltration into fractured rock at very low flow rates and for long equilibration times. We constructed several prototype instruments from porous stainless-steel membrane, stainless-steel casing, acrylic tubing, several temperature-compensated pressure transducers, solenoid valves, and a data logger for automated control and data acquisition. An automated refill system was also developed to facilitate long unattended equilibration periods typical in infiltration experiments on unsaturated fractured rock. Results show that the improved design reduces temperature effects on the infiltration rate, allows for much longer periods of unattended operation (auto-refill), and reduces evaporation from the infiltrometer. The estimated upper flow-rate limit of our new infiltrometer is about 1 mm d super(-1), based on the conductance of the porous steel membrane (11 mm d super(-1)). We were able to make measurements of the fluid flux as low as 10 mm yr super(-1) at a pressure head of about -110 cm.

Policies to control non-point pollution from agricultural production can be classified as command and control or economic incentive policies. In application of a command and control policy, a regulator (usually a government agency) mandates a reduction in emissions or limits an agricultural production activity. Examples are a mandated reduction in nutrient application, or a reduction in emission of a nutrient to streams. Economic incentive policies are designed to achieve the same level of pollution control, while allowing some flexibility in maximizing profit. A tax on inputs is one frequently cited incentive measure. In this study, alternative policies to reduce non-point emissions from agriculture on the Columbia Plateau of Washington, Oregon and Idaho are evaluated. The environmental efficiency and effects on profits by reduction of nitrogen from fertilizer under command and control regulation and tax incentives are compared.

In this study, soil surface elevation changes were measured every two weeks and soil crack volume was calculated for a two-year period at the USDA-Agricultural Research Service, Riesel Y-2 watershed in central Texas. Soil anchors were placed in triplicate at depths of 0.15, 0.45, 0.90, 1.50 and 2.5 m and relative movement from a monument at 4.5 m was measured. Soil movement was translated into crack volume assuming isotrophic shrinkage. A crack flow model was developed for this study that computes crack volume from crack potential, soil depth and soil moisture. Simulated crack volume followed the seasonal trends found in the measured crack volume and was in general agreement with a regression R super(2) = 0.84. The crack model was incorporated into SWAT (Soil and Water Assessment Tool), a comprehensive hydrologic model. Regression analysis was performed on measured and simulated daily surface runoff with an R super(2) = 0.87 indicating good agreement. The model was able to simulate surface runoff accurately in winter months when cracks were swelled closed and in the fall recharge events of 1998 when crack volume went from 70 to 10 mm. The relationships between measured crack volume and hydrologic variables simulated by the model were also examined and discussed.

The field had been cropped to no-till maize. NH sub(3) volatilization was measured with the micro-meteorological, integrated horizontal flux (IHF) method, and denitrification with a core incubation method using acetylene inhibition. An early-winter surface application (5 December 1996; 88 m super(3) ha super(-1) supplying 91 kg NH sub(4) super(+) -N ha super(-1)) was either unincorporated or immediately incorporated. NH sub(3) volatilization was measured from the unincorporated application, and denitrification from both slurry treatments and appropriate control soils. Total NH sub(3) loss from the unincorporated slurry application was 19% of applied NH sub(4) super(+) -N; temperatures were cool (4-6 degree C), and 25 mm of rain fell within 24 h of application. For 3 months, enhanced denitrification occurred from the two slurry treatments, with generally higher rates from the incorporated slurry. Total net denitrification loss from the surface-applied and incorporated slurry treatments was, respectively, 11 and 17% of applied NH sub(4) super(+) -N. Denitrification loss over the winter/early-spring period was appreciable but not substantial, even where NH sub(3) volatilization was restricted by immediate incorporation. From the spring application (30 April 1997, 39 m super(3) ha super(-1) supplying 51 kg NH sub(4) super(+) -N ha super(-1)), total NH sub(3) loss was 71% of applied NH sub(4) super(+) -N. These NH sub(3) volatilization loss data and the similarity of climate suggest that NH sub(3) loss factors from recent NW European work are likely to be generally applicable in the mid-Atlantic region.

These environmentally safe polymers are employed in various sensitive uses including food processing, animal feeds, and potable water purification. The most common synthetic polymer is anionic, high purity polyacrylamide (PAM), which typically provides 70 - 90% contaminant elimination. Excellent results are achieved adding only 10ppm PAM to irrigation water, applying 1 - 2kgha+1 per irrigation, costing $4 - $12kg+1. Biopolymers are less effective. Using twice or higher concentrations, existing biopolymers are #~60% effective as PAM, at 2 - 3 times the cost. A half million ha of US irrigated land use PAM for erosion control and runoff protection. The practice is spreading rapidly in the US and worldwide. Interest in development of biopolymer surrogates for PAM is high. If the supply of cheap natural gas (raw material for PAM synthesis) diminishes, industries may seek alternative polymers. Also 'green' perceptions and preferences favor biopolymers for certain applications.

AN - 67215559; 15612798 AB - Ring-labeled [14C]-3-chloro-4-methylaniline hydrochloride (250 microg per bird) was delivered to 21 red-winged blackbirds (Agelaius phoeniceus) and 21 dark-eyed juncos (Junco hyemalis) via oral gavage, and the distribution and excretion of radioactivity were determined at 15 and 30 min and 1, 4, 8, 12, and 24 h (n = 3 per time point). Direct measurement of radioactivity as well as measurement following combustion was accomplished using a liquid scintillation counter. Elimination from most tissues followed a two-compartment model, with very rapid elimination occurring between time 0 and 4 h and a much slower elimination phase occurring after that. The average half-life of elimination for the initial phase in most tissues examined was 0.16 h for juncos and 0.62 h for blackbirds. The average for the slower second phase of elimination was 3.4 h for juncos and 5.4 h for blackbirds. The radioactivity in blackbird kidney tissues did not change significantly for the duration of the test, pointing toward the kidney as a possible site of action for this important agricultural chemical.

AN - 67196729; 15612761 AB - The yeast Saccharomyces cerevisiae was used in a high-throughput bioassay to identify phenolic agents for control of the aflatoxigenic fungus Aspergillus flavus. Veratraldehyde, 1, cinnamic acid, 5, and the respective benzoic acid derivatives vanillin, 2, vanillic acid, 3, and vanillylacetone, 4, and cinnamic acid derivatives o-coumaric acid, 6, m-coumaric acid, 7, and p-coumaric acid, 8, showed significant antifungal activities (from highest to lowest, 2, 5 > 1 > 6, 7 > 4 > 3, 8) in the yeast system, with caffeic acid, 9, having little to no effect. Antifungal activity levels against A. flavus were similar. This similarity in antifungal activity demonstrated the usefulness of the S. cerevisiae bioassay for screening antifungal compounds. Assays using deletion mutants of yeast identified signal transduction and antioxidative stress response genes important to fungal tolerance. Targeting the antioxidative stress response system with certain compounds (e.g., 4) in combination with strobilurin fungicides had a synergistic effect against both fungi.

The purpose of this work was to develop a new approach to remove propachlor residues from the environment via chemical remediation by the nitrification inhibitor thiourea. The transformation processes of propachlor and thiourea mixed in aqueous solution, sand, and soil were elucidated. Analysis of transformation products and reaction kinetics indicated that an S sub(N)2 nucleophilic substitution reaction occurred, in which the chlorine of propachlor was replaced by thiourea, detoxifying the herbicide. It appears that propachlor undergoes a catalytic reaction in sand or soil amended with thiourea, which results in a significantly accelerated transformation rate as compared to the reaction in aqueous solution. The second-order reaction process was examined at different temperatures to investigate the role of the activation energy. The enthalpy of activation ( Delta H) for the reaction of propachlor with thiourea was demonstrated to be significantly lower in sand than in aqueous solution, which provides evidence that a catalytic transformation mechanism occurs in thiourea-amended sand. The chemical reaction rate increased proportionally to the amount of thiourea added to the sand. Column experiments further suggested that the remediation strategy could be used to remove propachlor residues from sand or soil to reduce leaching and prevent contamination of surface water and groundwater.

AN - 67262015; 15309337 AB - Chloropicrin (CP) and metam sodium are commonly used as fumigants in agricultural soils in order to provide effective control of nematodes, soil-borne pathogens, and weeds in preparation for planting of high-value cash crops. Repeated application of these compounds to agricultural soils for many years may result in the enrichment of microorganisms capable of degrading them. In this study, a microcosm-enrichment approach was used to investigate bacterial populations that may be components of metam-sodium- and CP-degrading microorganisms in compost-amended soils. After 6 months incubation, with repeated application of metam sodium and CP, degradation was > or =70% faster in compost-manure-amended (CM) soil compared to < or =50% in the unamended soils. The accelerated fumigant degradation may have been due to the addition of compost or to the development of new microbial populations with enhanced degradation capacity. Denaturing gradient gel electrophoresis (DGGE) profiles of PCR-amplified regions of 16S rRNA genes were used to identify dominant bacterial populations responsible for the accelerated fumigant degradation. The DGGE results indicated that specific bacterial types had been enriched and these were similar to strains isolated from basal minimal media. Fragments from DGGE bands and colonies were cloned, sequenced, and compared with published 16S rRNA sequences. Cloned sequences were dominated by Pseudomonas, Bacillus, Arthrobacter, Mycobacterium and uncultured bacterial species. The addition of organic amendment to soil during fumigation practices has the potential to increase the diversity of different microbial species, thereby accelerating fumigant degradation and reducing atmospheric emissions.

AN - 67260980; 15714231 AB - One of the most common vehicles by which Escherichia coli O157:H7 may be introduced into crops is contaminated irrigation water. Water contamination is becoming more common in rural areas of the United States as a result of large animal operations, and up to 40% of tested drinking-water wells are contaminated with E. coli. In this study, 2 contrasting soil samples were inoculated with E. coli O157:H7 expressing green fluorescent protein through irrigation water. Real-time PCR and culture methods were used to quantify the fate of this pathogen in phyllosphere (leaf surface), rhizosphere (volume of soil tightly held by plant roots), and non-rhizosphere soils. A real-time PCR assay was designed with the eae gene of E. coli O157:H7. The probe was incorporated into real-time PCR containing DNA extracted from the phyllosphere, rhizosphere, and non-rhizosphere soils. The detection limit for E. coli O157:H7 quantification by real-time PCR was 1.2 x 10(3) in the rhizosphere, phyllosphere, and non-rhizosphere samples. E. coli O157:H7 concentrations were higher in the rhizosphere than in the non-rhizosphere soils and leaf surfaces, and persisted longer in clay soil. The persistence of E. coli O157:H7 in phyllosphere, rhizosphere, and non-rhizosphere soils over 45 days may play a significant part in the recontamination cycle of produce in the environment. Therefore, the rapidity of the real-time PCR assay may be a useful tool for quantification and monitoring of E. coli O157:H7 in irrigation water and on contaminated fresh produce.

AN - 67235725; 15633690 AB - To successfully implement a hazard analysis critical control point plan, prerequisite programs are essential. Sanitation standard operating procedures are an important part of such a plan and can reduce contamination levels so that food safety and quality are not adversely affected. Noncontact surfaces in the shell egg processing plants can serve as a reservoir of cross-contamination. The objective of this study was to assess the efficacy of sanitation programs used in a variety of shell egg processing facilities (in-line, off-line, and mixed operations). Fourteen different noncontact surfaces were sampled in nine commercial facilities across the southeastern United States. Non-egg-contact surfaces were defined as those where the shell egg does not come into direct contact with the surface or with the fluid from that surface. Gauze pads soaked in sterile phosphate-buffered saline were used for sampling at the end of a processing day (POST) and again the next morning prior to operations (PRE). Aerobic plate counts (APCs) and numbers of Enterobacteriaceae were determined. No significant differences (P > 0.05) were found between POST and PRE counts for either population recovered from the 14 sampling sites. Only samples from the floor under the farm belts, nest-run loader, washers, and packer heads were reduced by 1 log CFU/ml of rinsate for APCs or Enterobacteriaceae counts. APCs of more than 10(4) CFU/ml of rinsate were recovered from many samples. Highest APCs were found on the floor under the farm belt and on shelves of the nest-run carts. High APCs were found on the wheel surface for off-line carts and on the loading dock floor. Highest Enterobacteriaceae counts were found in samples from the floor, drain, and nest-run egg cart shelves. A lack of significant difference between POST and PRE counts indicates that current sanitation programs could be improved. These data suggest that traffic patterns for the movement of eggs and materials through the plant should be reevaluated so that cross-contamination is reduced.

AN - 67229266; 15666858 AB - Improved vaccines to control Marek's disease (MD) in chickens are desired by the poultry industry but have been difficult to develop. Studies were conducted to evaluate strategies for deriving MD vaccines of high protective efficacy, irrespective of virulence. Candidate viruses from parent strains representing v and vv+ pathotypes were modified by cell culture passage, backpassage in chickens, or insertional mutagenesis following cocultivation with retroviruses. Ten strains considered most likely to exhibit high protective efficacy were selected for further study. The ability of these modified viruses to protect commercial or maternal antibody-positive (ab+) chickens against virulent MD virus (MDV) challenge was compared with that of strain CVI988, the standard commercial MD vaccine. Modified strains were also evaluated for the ability to induce lymphomas or other pathologic changes in ab+ and antibody-negative (ab-) chickens. Two of the 10 modified viruses, strains RM1 and CVI988/BP5, provided high levels of protection against highly virulent MDV challenge. The magnitude of protection was greater than that of one laboratory and two commercial preparations of CV1988, but was approximately equal to that of two other commercial preparations of CVI988 in laboratory and field tests. Three of the strains, including RMI and CVI988/BP5, induced lymphoid organ atrophy in ab-chicks but not in ab+ commercial chicks, a property designated here as L phenotype. Seven strains, including two L+ strains, were mildly oncogenic for ab- chicks, a property designated here as O phenotype. Five of these strains caused no tumors in ab+ chickens. The two fully attenuated strains induced neither lymphomas nor lymphoid organ atrophy. The L and O phenotypes appeared not to be linked, and both (especially the L phenotype) appeared associated with high levels of protection. These studies also illustrated differences in the protective efficacy of different preparations of CVI988 vaccine, indicating the need to choose carefully the most protective strains as controls for efficacy studies. A new vv+ strain, designated as 686, is described and appears useful as a challenge virus; it is the most virulent of the 48 field isolates of MDV thus far pathotyped in this laboratory. These findings support the conclusion that new virus strains with high levels of protective immunity comparable to that of CVI988 can be developed. However, the question of whether strains can be developed that exceed the efficacy of current CVI988-based vaccines remains unanswered. After more than 30 years of unsuccessful endeavor by many laboratories toward this goal, it now may be useful to consider whether the efficacy of MD vaccines is limited by some type of biologic threshold.

AN - 67218457; 15633677 AB - Mycobacterium avium subsp. paratuberculosis, the causative agent of a chronic enteritis in ruminants (Johne's disease), has been linked to Crohn's disease in humans. This microorganism is shed by infected animals primarily in the feces but is also shed in the milk at much lower levels. Therefore, dairy products from infected animals may be one mode of transmission of this animal pathogen. This study was designed to evaluate the effectiveness of the holder and high-temperature short-time pasteurization standards on the destruction of M. paratuberculosis. One hundred eighty experiments were conducted in this study using a slug-flow pasteurizer unit and a laboratory scale pasteurizer unit. Ultrahigh-temperature milk was inoculated at two concentrations, 10(8) and 10(5) CFU/ml, with three different field strains of M. paratuberculosis. Five different time-temperature combinations were evaluated: 62.7 degrees C for 30 min, 65.5 degrees C for 16 s, 71.7 degrees C for 15 s, 71.7 degrees C for 20 s, and 74.4 degrees C for 15 s. Three replicates of each experiment were run for the pasteurizer unit, time-temperature combination, and strain of M. paratuberculosis. Treatment of milk regardless of bacterial strain or pasteurizer unit resulted in an average 5.0- and 7.7-log kill for the low and high concentrations of inoculum, respectively. Milk treated for cheese production (65.5 degrees C for 16 s) resulted in a much lower and more variable kill. Results from this study indicate that the current U.S. minimum standards for batch and high-temperature short-time pasteurization of grade A milk significantly reduced the survivability of M. paratuberculosis, but some bacteria survived subpasteurization heat treatment of milk used for cheese manufacture.

AN - 67218347; 15633667 AB - The current project was conducted to determine the microbial quality of commercially processed shell eggs during extended storage. Unwashed eggs were collected at the accumulator before entering the processing line. Washed eggs were retrieved after placement in flats. All eggs were stored on pulp flats at 4 degrees C for 10 weeks. Twelve eggs from each treatment were rinsed on the day of collection and during each week of storage. After rinsing, eggs were sanitized in ethanol, and contents were aseptically collected. Total aerobes, yeasts and molds, Enterobacteriaceae, and pseudomonads were enumerated from shell rinses and pooled egg contents. During storage, no differences were found between unwashed and washed eggs for Enterobacteriaceae and pseudomonads in either shell rinses or contents. No differences were found between treatments for population levels of total aerobes or yeasts and molds in the egg contents throughout the storage period. Significant differences between treatments were found at each week of storage for external shell contamination by total aerobes. The highest unwashed egg contamination occurred at week 8 of storage and the lowest was at weeks 0 and 1 of storage. The highest shell contamination with aerobic bacteria on the washed eggs was found at week 0 of storage and the lowest was at week 7. Yeast and mold contamination determined by shell rinses was also significantly different between treatments at each week of storage. Commercially washed eggs were significantly less contaminated than were unwashed eggs for the populations monitored.

AN - 67217578; 15669394 AB - Successful feeding by mosquitoes through permethrin-treated battle-dress uniforms (BDUs) was observed in the Shoalwater Bay Training Area (SWBTA), Queensland, Australia, during Operation Tandem Thrust 1997 (TT97). Therefore, during Operation Tandem Thrust 2001, the repellency of permethrin-treated BDUs was evaluated. Washing permethrin-treated BDUs 1 time reduced the permethrin concentration by 60%, but permethrin concentration was not reduced further after subsequent washings (up to 20 times). The probing time of Ochlerotatus vigilax landing on permethrin-treated BDUs was reduced to the greatest extent on the treated, unwashed uniform (7.5-fold reduction). Treated, washed uniforms also reduced probing time (2.5 times) compared to the untreated control uniform containing no permethrin. Reduced probing time should reduce feeding success and protect operational forces from bothersome mosquitoes and the associated risk of mosquito-borne disease in SWBTA. Observations of successful mosquito feeding made during TT97 could be attributed to the use of old and well-worn BDUs and seasonal differences in mosquito population density.

Characterization of soil water content (theta , m (super 3) m (super -3) ) may be especially difficult in mountainous, snow-dominated catchments due to highly variable water inputs, topography, soils and vegetation. However, individual sites exhibit similar seasonal dynamics, suggesting that it may be possible to describe spatial variability in terms of temporally stable relationships. Working in a 0.36 km (super 2) headwater catchment, we: (i) described and the spatial variability of theta over a 2 year period, (ii) characterized that variability in terms of temporal stability analysis, and (iii) related changes in temporally stable soil water patterns to stream flow generation. Soil water data were collected for 2 years at representative sites and quantified in terms of theta and water storage to a depth of 75 cm (S (sub 75) , cm). Both S (sub 75) and theta were normally distributed in space on all measurement dates. Spatial variability was high relative to other studies, reflecting catchment heterogeneity. However, the ranking of S (sub 75) values displayed temporal stability for all site locations, seasonally and annually. This stability was attributed to soil texture. Further temporal analysis indicated that estimates of catchment mean and standard deviation of S (sub 75) may be characterized with relatively few measurements. Finally, we used temporal linear regression to define catchment soil water conditions related to stream-flow generation. Static, high S (sub 75) conditions in late winter and early spring indicate that stream-flow response is highly sensitive to inputs, whereas static, low S (sub 75) conditions in late summer and early fall indicate minimum stream-flow sensitivity to water inputs. The fall transition was marked by uniform S (sub d) across the catchment. The late spring transition was marked by nonuniform S (sub 75) decreases, with the highest S (sub 75) sites decreasing most. Threshold S (sub 75) values identifying catchment sensitivity to water input were identified.

In the past, veterinary services involved in this type of activity usually assessed risks qualitatively. However, since the 1990s, quantitative methods have become increasingly important. The establishment of the World Trade Organization in 1994, and the promulgation of its Agreement on the Application of Sanitary and Phytosanitary Measures (the 'SPS Agreement') led to an increased application of import risk analysis and to significant improvements in the methodology of risk analysis as applied to international trade policy for animals and animal products. However, there was very little development of risk analysis in veterinary fields other than international trade and management of health risks to consumers of animal products and little has been published on its use in the choice and definition of control or prophylaxis strategies for animal diseases. This article describes a quantitative risk assessment, which was undertaken in Italy to help choose an appropriate national response strategy following an incursion of bluetongue, an infectious disease of sheep and goats. The results obtained in this study support the use of risk analysis as a tool to assist in choosing an appropriate animal disease management strategy. The use of risk analysis in the evaluation of disease management strategies also offers advantages in international trade. It makes easier the comparison of different strategies applied in the various countries, and thus facilitates the assessment of equivalence of the guarantees provided by different strategies.

Reconciling tradeoffs between these risks and benefits is contingent upon informed, directed, and two-way communication between wildland fire managers and stakeholders. In an effort to aid with the design of such a communication effort, this study used mental models research to determine the unique wildland fire information and decisionmaking needs of stakeholders living at the wildland-urban interface of a fire-prone area. While the analysis revealed many similarities in how stakeholders conceptualized the risks and benefits of wildland fire, many misconceptions and important gaps in understanding on the part of both expert and nonexpert respondents were identified.

A oversowing field experiment determined if this problem was because of poor nodulation. Four renovation techniques, clipped sward (treatment A), herbicided + rye seeding in the previous autumn (treatment B), herbicided in the autumn and spring (treatment C) and herbicided to suppress the sward (treatment D), were investigated to determine their effect on nodulation and root growth of lucerne (Medicago sativa L.), red clover (Trifolium pratense L.) and white clover (T. repens L.) at 16, 22 and 29 d after sowing the legumes. A pot experiment was also conducted under optimal growth conditions and using the same soil to determine the nodulation and root growth potentials of these legume species. At adequate rhizobial populations (>6 x 10 super(4) cfu g super(-1) soil), substantial nodulation of all species occurred by 29 d after sowing in treatments C and D, whereas nodulation of clovers was usually reduced in treatment A. Total root lengths for all sampling dates, species and treatments were severely restricted, especially under treatment A. A general correspondence of nodulation with root growth was observed for all species, with high correlations (r . 0.85) between these variables for all legume species and treatments, suggesting that soil moisture, and possibly competition for light, were the limiting factors. These results demonstrate that weak stands of forage legumes, typically found when sown into tall fescue swards, are probably not because of inadequate nodulation. Rather, inhibition of root growth by detrimental physical/chemical conditions or allocation of limited photosynthate to shoots instead of roots is suggested.

In the invasive plants arena, risk assessment efforts have focused on classifying the invasive potential of nonindigenous plants. Currently, however, the field of risk assessment for invasive species is in an early stage of development, and there is a lack of broad scientific principles or reliable procedures for identifying the invasive potential of plants in new geographic ranges. Furthermore, identifying potential hazards may be just the first step in a more comprehensive risk assessment. At least for those regulatory decisions that may be disputed internationally or domestically, scientifically ambitious risk assessment for invasive plants is not optional. Therefore, there is a pressing need to formulate adaptable, biologically plausible methods and approaches in this emerging field that strike an appropriate balance between the demand for accuracy and precision in predicting risks and the constraints of limited information, time, and other resources.

Unfortunately, little information is available about most of Florida's invasive species. Here, we provide information on range expansion of a population of one of the lesser-known species. The Palm Beach County, Florida, population of the northern curly-tailed lizard, Leiocephalus carinatus armouri, was examined for north-south expansion of its previously documented range. Observations were conducted as contiguous expansion outward from the previously known range. We found a substantial contiguous range expansion by a minimum of 46.3 km to the south and 34.1 km to the north. This species appears to be closely associated with coastal habitat degradation in the form of human infrastructure, especially ageing pavement, sea walls, buildings, and bridge bases.

This sharpshooter, vector of Pierce's disease bacteria Xylella fastidiosa Wells, expanded its geographical distribution and it has become a very serious pest problem in several crops, especially grapes, in southern California. In 2000, a survey of sharpshooter egg parasitoids was initiated in Argentina. Fourteen species of egg-parasitoids were collected. We report here on laboratory studies of adult longevity, oviposition preference, sex ratio, and development time of Zagella delicata De Santis. Field result of the incidence on its hosts and seasonal occurrence also are provided. Zagella delicata produced one adult per host egg. The overall results indicated that 72.5% of the sharpshooter eggs exposed to Z. delicata were parasitized. Wasps emergence was 43.8%. In host plant searching preference tests, Z. delicata females parasitized 66.7% of host eggs on sugar cane, 57.0% of eggs on corn and 4.5% on citrus leaves. The development time (from oviposition to adult emergence) averaged 23.5 plus or minus 1.2 days. The average adult longevity was 10.3 plus or minus 5.8 days. Females lived longer than males (females: 12.2 plus or minus 5.6 days, males: 6.2 plus or minus 3.7 days). The sex ratio in the laboratory was 1: 2.1 (males/females). In a hyperparasitism test, no adults of Z. delicata emerged from eggs previously exposed to Gonatocerus tuberculifemur. Seasonal sampling carried out in San Miguel de Tucuman showed that Z. delicata occurred from spring to fall, with maximum abundance at the beginning of the spring, where 57.2% out of the 1568 sampled eggs were parasitized. Field and laboratory data suggest that Z. delicata could be a prospective biological control agent against other, exotic, proconiine sharpshooters including H. coagulata. However, the efficiency of Z. delicata is restricted to habitats dominated by grasses.Original Abstract: RESUMEN Las investigaciones sobre el control biologico de Homalodisca coagulata (Cicadellidae: Proconiini) fueron iniciadas en la decada del 90. Esta chicharrita, vector de la bacteria Xylella fastidiosa, expandio su area de distribucion geografica y aumento su abundancia transformandose en una seria plaga de varios cultivos, especialmente en la vid, en el sudeste de California. En el ano 2000 fue iniciada una exploracion de parasitoides de huevos de chicharritas proconiinas en Argentina, donde fueron colectadas 14 especies de parasitoides. Aqui se reportan los resultados de campo y laboratorio de uno de estos parasitoides, Zagella delicata De Santis, aportando informacion sobre su bionomia (longevidad de adultos, preferencia de oviposicion, proporcion de sexos y duracion del desarrollo), incidencia sobre su hospedador en el campo, y ocurrencia estacional. Zagella delicata produjo un solo adulto por huevo. En general, parasito el 72.5% de los huevos y emergiendo avispas del 43.8% de los huevos parasitados. En las pruebas de preferencia de oviposicion de planta hospedadora, las hembras de Z. delicata parasitaron 66.7% de los huevos en cana de azucar, 57.0% de los huevos en maiz y fueron atacados 4.5% de los huevos depositados en Citrus. La duracion del tiempo de desarrollo (desde huevo a adulto) fue de 23 plus or minus 1.2 dias. La longevidad promedio de los adultos fue de 10.3 plus or minus 5.8 dias. Las hembras vivieron mas que los machos (hembras: 12.2 plus or minus 5.6; machos: 6.2 plus or minus 3.7 dias). La proporcion de sexos en el laboratorio fue de 1: 2.1 (machos /hembras). En los estudios de hyperparasitismo, ningun adulto de Z. delicata emergio de huevos previamente expuestos al mymarido Gonatocerus tuberculifemur. El muestreo estacional realizado en San Miguel de Tucuman mostro que Z. delicata aparece desde la primavera hasta el otono, con maxima abundancia a principios de la primavera, donde el 57.2% de los 1568 huevos muestreados estaban parasitados. Los estudios de campo y laboratorio sugieren que Z. delicata tiene potencialidades como agente de control biologico de otras chicharritas proconiinas exoticas incluyendo a H. coagulata. Sin embargo, Z. delicata esta circunscripta a habitats dominados por gramineas.Translation provided by the authors.

A laboratory study was designed to test the effects of saturated CO sub(2), freeze-thaw cycles and different freezing protocols on C. parvum oocysts in aquifer material. Oocysts were exposed to a saturated solution of CO sub(2) at room temperature for 1-, 4-, 8-, and 12-h intervals and their viability was compared with controls. One- and three-cycle freeze-thaw experiments on oocyst survival were conducted. Inactivation of oocysts was assessed for: (1) rapid freezing and rapid thawing and (2) gradual freezing and rapid thawing. Exposure to 1 atm of CO sub(2) in water at room temperature had a negligible effect on oocyst viability. Average oocyst viability after the one- and three-cycle freeze-thaw experiments was 24.7 and 2.7%, repsectively. The average oocyst viability associated with the rapid freeze-thaw and gradual freeze-thaw experiments was 11.3 and 26.2%, respectively. Freezing associated with injection of liquid CO sub(2) into aquifers would be the factor inactivating oocysts; to cause a 3-log decrease in oocyst viability multiple injections may be required.

Vaccinium species also have a long history of human use. However, little research has been done to ascertain how they respond to common forest management practices. We used data obtained from old-growth, young thinned, and young unthinned Douglas-fir stands in western Oregon to evaluate how forest management could potentially influence species abundance and product supply. Our analysis focused on three species: Vaccinium ovatum, V. parvifolium, and V. membranaceum. Results were variable, but indicate that overstory stand conditions and forest management can affect huckleberry species abundance. However, to assess fully the effects of forest management on these species, studies specifically designed to target areas where people harvest these products are needed. Measuring relevant product attributes such as commercial productivity is also critical.

To date, much of this concern seems to be directed at the fast food segment of the restaurant industry. This paper asks whether targeting one segment of the industry, such as fast food restaurants, is justified, or whether a more balanced view of eating away from home is required. To answer this question, we look to the future and ask whether Americans can be expected to purchase increasingly more fast food or more-and-more of the foods typically associated with full-service dining. One view is that sales at full-service restaurants will now grow relatively faster than sales of fast food. The argument supporting this position rests on rising incomes, the aging of the population, smaller household sizes, and other changes taking place in the population. Using a new full-information maximum likelihood procedure for estimating a system of censored expenditure equations, we find evidence to support this argument.

Each herbicide was applied at eight doses. Data were regressed on herbicide dose using a log-logistic curve (R2 = 0.56-0.95 for clethodim, R2 = 0.60-0.94 for glufosinate, and R2 = 0.70-0.96 for glyphosate). The herbicide rate that elicited a 50% plant response (I50) in the bermudagrass cultivars ranged from 0.04 to 0.19 kg ha-1 clethodim, 0.19 to 1.33 kg ha-1 glufosinate and 0.34 to 1.14 kg ha-1 glyphosate. Relative to other cultivars, common bermudagrass was intermediate in its response to clethodim and among the most tolerant cultivars to glufosinate and glyphosate. TifSport was relatively tolerant to clethodim and glufosinate compared with other cultivars, but relatively sensitive to glyphosate. One cultivar, 94-437, was consistently among the most sensitive cultivars to each of the herbicides. While there were differential herbicide tolerances among the tested bermudagrass cultivars, there did not appear to be any naturally occurring herbicide resistance that could be commercially utilized. However, research indicated that breeding efforts should target herbicide resistance that is at least four times the registered use rate. Also, TifSport and Tifway have been identified as suitable representatives of triploid hybrid bermudagrass cultivars to be used to evaluate the success of turfgrass renovation programs.

One substantial challenge in invasive plant management is the evolution of resistance to herbicides, biological control, and other treatments. We show how the tools of quantitative genetics and selection analysis can be used to investigate the potential for evolution of resistance, which can aid in the management of invasive plant populations. We also illustrate how invasive species research can be used to test theory, such as the evolution of increased competitive ability hypothesis. We outline the methods to investigate this theory and recommend including evolutionary considerations in invasive species management.

Unfortunately, a reduction of body weight has been correlated with a reduction in bone mass, the reasons for which have not been fully elucidated. The importance of maximizing peak bone mass during premenopausal years is well known. Most studies demonstrate a positive relationship between calcium intake and bone mass. However, during caloric restriction, which is commonly used for weight loss, calcium intake has shown mixed results. Calcium from dairy sources has received additional attention, beyond its importance to bone, for its role in regulating body weight and composition. Dairy foods are perceived as high fat, and therefore, are generally minimized or avoided during caloric restriction. The current calcium intake for premenopausal women is significantly below recommendations, and even if met during caloric restriction, may not be adequate. This review underscores the need for maintaining at least adequate intake levels of calcium, if not more, during weight loss regimens to minimize potential long-term detrimental effects on bone metabolism.

The abundance of adult sap beetle species inhabiting 95% were Colopterus truncatus and Carpophilus sayi. C. fagacearum was isolated from 75% of 594 adults assayed for the fungus. The average number of viable propagules for pooled data of individuals of each species ranged from < 100 to 18,000. Frequencies of fungus isolation differed by days after wounding, study location, and sap beetle species. These results, when coupled with previous findings on predominant species associated with oak wilt fungi mats, support the hypothesis that Co. truncatus and Ca. sayi are the principal sap beetle species transmitting C. fagacearum from diseased to healthy oaks in Minnesota.

However, most loblolly pine growth-and-yield models predict growth after crown closure has occurred. In this article, we describe the development and implementation of a system of equations designed to simulate growth of loblolly pine before the onset of intraspecific competition. Treatment response functions were also developed for various site preparation, herbaceous weed control, and fertilization practices. These functions modify the baseline model predictions to simulate the effects of treatments on tree growth and stand development. This system was incorporated into the PTAEDA2 growth-and-yield simulator to make growth projections from time of planting through rotation age for intensively managed stands of loblolly pine in the southeastern United States. Growth simulations specifying either bedding or disking showed increases in volume growth for both treatments. The shear-and-pile site-preparation method reduced growth rates slightly. Volume growth responses to herbaceous weed control were positive, with magnitude of increase largely depending on duration of treatment. Increases in volume attributable to fertilization at planting were related to types of element applied. The largest predicted response was for phosphorus fertilization, whereas application of potassium was the least effective fertilization treatment. Site preparation, weed control, and fertilization treatment combinations produced additional volume gains when compared to single treatments, while maintaining predicted values that are within biological limits for loblolly pine growth.

The addition of the precompetitive growth system did not significantly affect the predictive behavior of the PTAEDA2 model for untreated stands. FOR. SCI. 50(6):823- 835.

In 1997, we surveyed 33 owl sites that, in the previous four years, had burned at various levels ranging from light controlled burns to stand-replacing fires. We compared owl occupancy and reproduction in these burned sites to 31 unburned owl sites with similar habitat and topography. Although unburned sites showed higher proportions of both occupancy and reproduction, the negative relationship observed between recent fire occurrence and owl occupancy rank was statistically weak (Test for Marginal Homogeneity, P = 0.110). Owls tended not to be present where pure pine stands (Pinus spp.) comprised a large proportion (38- 85% ) of burned sites, but no other factors relating to habitat or fire severity had a significant, biologically interpretable influence on occupancy rank. We suspect that relatively low-intensity ground fires, including most prescribed fires, probably have little or no short-term impact on Mexican spotted owl presence or reproduction, but we have no data on long-term effects of fire. We recommend proactive fuels-management treatments in areas not currently occupied by owls as a means of reducing fire risk in areas occupied by owls. Within areas occupied by owls, judicious treatments may be appropriate after case-by-case evaluations of potential benefits and risks within those sites. FOR. SCI. 50(6):765- 772.

AN - 20260279; 8894143 AB - Can a tree-specific mortality model elicit expected forest stand density dynamics without imposing stand-level constraints such as Reineke' s maximum stand density index (SDImax) or the -3/2 power law of self-thinning? We examine this emergent properties question using the Austrian stand simulator PROGNAUS. This simulator was chosen specifically because it does not use stand density constraints to determine individual tree mortality rates. In addition, it is based on a probability sample of the population that includes the span of the data being used to test the hypothesis. Initial conditions were obtained from 27 permanent research plots that were established in young pure stands of Norway spruce (Picea abies L. Karst.) and Scots pine (Pinus sylvestris L.) in Austria. A growth period of 250 years was simulated. We conduct our test in two parts. First, we compare our simulated results to Reineke' s theory of maximum density and stand density index by examining the self-thinning relationship between stem number per hectare and quadratic mean diameter (log-log scale). Second, we compare our results to Sterba' s full competition density rule, which incorporates dominant height along with stem number and quadratic mean diameter. From the results for Norway spruce, we conclude that stand-level density constraints are not necessary to obtain Reineke' s maximum size-density relations. Norway spruce results confirm that the maximum size-density relationship reflects reasonable and stable stand dynamics and conforms to that expected by Reineke' s theory. Results from simulation of Scots pine also display reasonable and stable stand dynamics, except that they greatly exceed Reineke' s maximum stand density index determined empirically from the literature. This Scots pine result argues for stand-level constraints (such as specifying SDImax) to ensure that the appropriate intercept for the maximum density line is used. Our second test revealed that the estimated maximum stand density index according to Sterba' s theory was too high for both species, but that the relative rankings across plots were correct. Thus, we are left with ambiguous results. First, that a density-dependent individual-tree mortality model, developed on an adequate data set, is sufficient for the desired stand-level behavior of Reineke to emerge. Second, that stand-level constraints on SDImax need to be imposed if the underlying mortality modeling database is not adequate. FOR. SCI. 50(6):848- 858.

The complementarity of the microscopy methods, scanning electron microscopy, electron probe microanalysis and atomic force microscopy assessed and correlated form and function of the surface modifications. Stainless steel disks (1 cm in diameter) were laser-cut from the same sheets of stainless steel and treated by electropolishing or left untreated for controls. Each treatment was analysed separately using each technique. First, the disks were examined by visual inspection and electron probe microanalysis for surface characteristics and elemental composition, respectively. Aliquots of bacterial suspensions (saline rinses of poultry carcasses from a commercial broiler processing plant) were then diluted in broth and monitored for growth by spectrophotometry. Stainless steel disks (1 cm in diameter) were added and the cultures were grown to sufficient density to allow attachment of bacterial cells to test surfaces. Relative differences in the surface morphology shown by atomic force microscopy, including Z ranges, roughness and other measurements, corresponded by treatment with the differences in reduction of bacterial counts shown by scanning electron microscopy. A model of wet-processing conditions tested the effects of corrosive treatment of surfaces. Less bacterial attachment occurred after corrosive treatment on controls and electropolished samples. Electropolishing significantly reduced bacterial numbers and the effects of corrosive action compared to the controls. Thus, the multiple imaging techniques showed that engineered changes on stainless steel surfaces improved the resistance of the surface finish to bacterial attachment, biofilm formation, and corrosive action.

Deaths are mainly due to secondary complications, including Staphylococcus aureus (SA) infections. Vitamin E (E) supplementation reduces influenza in aged mice. This study determined the efficacy of E supplementation on secondary bacterial infections after influenza in young and old mice. C57BL/6 mice were fed diets containing 30 or 500 ppm E for 4 weeks. Priming with influenza significantly increased SA in the lungs of infected mice fed control diet. Age did not have a significant effect on SA infection alone or SA infection after influenza infection. E supplementation did not have a significant effect on SA infection alone. However, E supplementation abolished the priming effect of influenza on SA.

Circumstantial evidence suggests that oocyst-induced infections in humans are clinically more severe than tissue cyst-acquired infections. Until recently, water-borne transmission of T. gondii was considered uncommon but a large human outbreak linked to contamination of a municipal water reservoir in Canada by wild felids and the widespread infection by marine mammals in the USA provide reasons to question this view. The present paper reviews information on the biology of oocyst-induced infections of T. gondii in humans and animals and examines possible importance of transmission by water.

Vaccination is a safe and effective means to prevent disease and to increase the productivity and profitability of farmed fish. Vaccines are likely to be the prime prophylactic measure of the future because of rapidly developing advances in fish vaccine technology and producer acceptance. The efficacy of a vaccine is influenced by a variety of factors that must be considered in the development of vaccination strategies for fish. This review highlights some of these factors. The response to a modified live vaccine against Edwardsiella ictaluri is used for illustration.

A. flavus infection and subsequent aflatoxin contamination is a serious issue in the southern US, especially during a drought. Field studies demonstrate that reduction of drought stress by irrigation reduces aflatoxin contamination in corn and peanut. Drought tolerant corn varieties were also found to produce significantly less aflatoxins in the field under drought conditions compared to aflatoxin-resistant controls. Genetic studies to identify QTLs for low levels of aflatoxin accumulation observed significant environmental effects on the location and number of QTLs between studies conducted at different locations and during different years. Proteomic comparisons of kernel proteins between corn genotypes resistant or susceptible to A. flavus infection have identified stress-related proteins along with antifungal proteins as associated with kernel resistance. Gene expression studies of plants in response to biotic or abiotic stress also found that disease resistance-related genes could be upregulated by abiotic stresses and vise versa. Further examination of host plant and pathogen interactions revealed that plant responses to abiotic stresses and pathogen infections were mediated through several common regulatory genes or factors. The presence of "cross-talk" between responses to abiotic stress and biotic stress provides new approaches for enhancing host resistance to biotic stresses through the upregulation of key signal transduction factors.

We used analysis of zinc-finger protein (Zfx and Zfy) DNA regions to determine gender of 96 beavers (Castor canadensis) from 3 areas and used these results to verify gender determined in the field. Gender was correctly determined for 86 (89.6%) beavers. Incorrect assignments were not attributed to errors in any one age or sex class. Although methods that can be used in the field (such as morphological methods) can provide reasonably accurate gender assignments in beavers, the genetic method might be preferred in certain situations.

In this study, we used mass-marking and recapture techniques to quantify the foraging distribution and abundance of red imported fire ants, Solenopsis invicta Buren, on individual bait cards from neighboring polygyne (multiple queens) colonies. Ants in six to eight adjacent colonies, at each of 10 sites, were mass-marked a unique color. Ants were collected at olive-oil baits in a 10 by 10-m area consisting of 61 baits at each site. Stepwise nonlinear regression showed that the distance to baits, colony size, and average internidal (between nests) spacing were significant predictors of the foraging distribution of ants from colonies. Most marked ants were collected within approximately 4 m of their colony. Foraging was more constrained at closer internidal distances. As internidal distances increased, colony foraging distances increased. There was a significant difference in the number of observed ants from colonies on individual baits compared with the expected number from the regression model. A chi 2 analysis showed that high numbers of ants on individual baits from a colony had a significant negative effect on the number of foragers from adjacent colonies. Results show approximately 66% of the variation in foraging can be explained through colony size, location, and recruiting ability; however, foraging interference among ants from adjacent colonies occurs and may result in unequal sharing of resources (i.e., resource partitioning) among colonies.

Photointerpretation of satellite imagery resulted in an average detection rate of 46.9 plus or minus 1.2% of mounds. Mound size and mound height had a significant effect on mound visibility. Predicted detection rates, based on mound height and mound area, ranged from 24% for small mounds (15 cm high, 0.05 m2) to 66% for large mounds (30 cm high, 0.30 m2). Limitations and possible uses for satellite imagery in fire ant mound detection are discussed.

The degree of contagion or aggregation of resources in a habitat can increase the probability of locust gregarization by increasing the frequency of contact among individual locusts. The spatial distribution patterns of two resources upon which gregarization can occur, the tussock grasses Aristida pungens and Panicum turgidum (Poaceae), were examined in two adjacent regions of the desert locust (Schistocerca gregaria Forskaal) plague recession area in Mauritania that differ in their frequencies of locust gregarization. The hypothesis that the distribution of grass tufts should be more aggregated and thus more likely to promote locust phase change in the high frequency gregarization area was tested. Tufts were more abundant, and both species were larger in the high frequency gregarization area. The spatial distribution patterns of tufts in both areas were largely aggregated at the 200- to 2000-m2 scale corresponding to the population-level scale of locust resources. As predicted, the degree of aggregation was more extreme across the high frequency gregarization area. This study provides support across a large area for the predicted association between local resource distribution and locust gregarization. The observed differences in grass abundance and size between the high and low frequency gregarization areas suggest that factors such as topography or hydrology may underlie differences in plant distribution and contribute to locust gregarization in the high frequency area.

Diurnally alternating temperatures were used to estimate rates of development at temperatures too low for nymphs to complete development under constant temperatures. Two previously published equations were fit to these data and used to predict developmental rates as a function of temperature. The first equation, nonlinear and only approaching zero rate of development asymptotically, was fit to the data from constant and alternating temperature treatments. The second equation, which included an intercept, was fit to the data from constant temperature treatments only. Estimated developmental times based on these equations were tested against observed developmental times in two fluctuating temperature regimes in growth chambers, and two seasons of field sampling. Elevation of body temperature of grasshoppers above ambient temperatures in the field was modeled as a linear function of solar irradiance, based on field measurements. The effect of behavioral thermoregulation on nymphal developmental times in the field was estimated using standard air temperatures and solar-adjusted temperatures. Rates of development under most of the constant temperature treatments were higher than any previously published for M. sanguinipes. Estimated rates of development in the field using air temperatures only were about one-half those using solar-adjusted temperatures. Observed developmental times in the field were 45 and 42 d in 2000 and 2002, respectively. Because of local adaptation and behavioral thermoregulation, duration of nymphal stages in M. sanguinipes is relatively independent of latitude.

Different boas were studied during three periods relative to Hurricane Georges: before only; before and after; and after only. Mean daily movement per month increased throughout the three periods, indicating that the boas moved more after the storm than before. Radio-tagged boas also became more visible to observers after the hurricane. Throughout the three periods, the sexes differed in movements, with males moving greater distances per move and moving more frequently than females. Males showed a bimodal peak of movement during April and June in contrast to the females' July peak. Sexes did not differ in annual home range size, which had a median value of 8.5 ha (range = 2.0-105.5 ha, N = 18) for 95 percent adaptive kernal. Females spent more time on or below ground than did males, which were mostly arboreal. Trees used by boas had larger diameters and more vines than random trees. Hurricane winds that strip leaves, vines, and branches from trees may reduce cover for boas and limit access to arboreal sites, at least for several years until succession brings about recovery with increased vine growth. Boas were especially difficult to observe; telemetrically monitored boas were detected visually at an average of only 15 percent of their fix sites, indicating that the species is more abundant than generally perceived.

Among the options available for effluent disposal is discharge into stream channels, through which effluent can help recharge the aquifer below. Effluent discharge into otherwise dry or intermittent streambeds in the Southwest has created new perennial stream reaches. Although these streams cannot be used for recreation, they develop riparian ecosystems and contribute to groundwater recharge. Effluent-dependent streams may provide the benefits of riparian ecosystems, but they also introduce potentially poor-quality water to the environment with the possible presence of organic and microbial contaminants. Therefore, understanding the fate and transport of any pollutants released into the stream and their potential effects on groundwater quality is important.

To better understand NPS pollution sources in mixed use watersheds, surface water samples were taken at three sites that varied in land use to examine the effect of land use on water quality. Within the group of three watersheds, one was predominately agriculture (Agricultural), one was predominately urban (Urban), and a third had relatively equal representation of both types of land uses (Mixed). Nitrogen (N), phosphorus (P), total suspended solids (TSS), turbidity, pH, temperature, and streamflow were measured for one year. Comparisons are made among watersheds for concentration and fluxes of water quality parameters. Nitrate and orthophosphate concentrations were found to be significantly higher in the Agricultural watershed. Total suspended solids, turbidity, temperature, and pH, were found to be generally higher in the Urban and Mixed watersheds. No differences were found for streamflow (per unit area), total phosphorus, and ammonium concentrations among watersheds. Fluxes of orthophosphate were greater in the Agricultural watershed that in the Urban watershed while fluxes of TSS were greater in the Mixed watershed when compared to the Agricultural watershed. Fluxes of nitrate, ammonium, and total phosphorus did not vary among watersheds. It is apparent from the data that Agricultural land uses are generally a greater source of nutrients than the Urban land uses while Urban land uses are generally a greater source of suspended sediment.

Because Cryptosporidium from most of these animals have been identified by oocyst morphology alone with little or no host specificity and/or molecular data to support identification it is not known how many of the reported isolates are actually C. parvum or other species. Cryptosporidiosis is a cause of morbidity and mortality in animals and humans, resulting primarily in diarrhea, and resulting in the most severe infections in immune-compromised individuals. Of 15 named species of Cryptosporidium infectious for nonhuman vertebrate hosts C. baileyi, C. canis, C. felis, C. hominis, C. meleagridis, C. muris, and C. parvum have been reported to also infect humans. Humans are the primary hosts for C. hominis, and except for C. parvum, which is widespread amongst nonhuman hosts and is the most frequently reported zoonotic species, the remaining species have been reported primarily in immunocompromised humans. The oocyst stage can remain infective under cool, moist conditions for many months, especially where water temperatures in rivers, lakes, and ponds remain low but above freezing. Surveys of surface water, groundwater, estuaries, and seawater have dispelled the assumption that Cryptosporidium oocysts are present infrequently and in geographically isolated locations. Numerous reports of outbreaks of cryptosporidiosis related to drinking water in North America, the UK, and Japan, where detection methods are in place, indicate that water is a major vehicle for transmission of cryptosporidiosis.

Fluorescence polarization (FP) was used to show that the binding equilibria between estrogen receptor- alpha or estrogen receptor- beta , and estradiol were not affected by ATR and its metabolites: ATR-desethyl (ADE), ATR- desisopropyl (ADI), ATR-desethyldesisopropyl (ADD) and terbuthylazine (TBZ). Therefore, ATR and its degradation products were studied to determine their ability to inhibit phosphodiesterase (PDE), the enzyme responsible for hydrolyzing the second messenger cAMP to 5'-AMP. Using FP, it was found that ATR inhibited PDE with an IC sub(50) value of 1.8 mu M. This was lower than the known PDE inhibitor isobutyl methylxanthine (IBMX), which had an IC sub(50) value of 4.6 mu M. The ATR degradation products ADE, ADI, ADD and TBZ were less effective than ATR at inhibiting PDE when assayed using FP. Classical competitive binding assays, using radiolabeled super(14)C-cAMP in conjunction with thin layer chromatography (TLC), were used to determine that ATR was a competitive inhibitor of PDE with an association constant of 85 mu M.

Spores of the bacterium were inoculated onto irradiated London broil beef at levels of 3 log10 spores/g beef. Samples of beef (7.510.01.0cm) were treated with aqueous ozone (5ppm O3 for 5min), or heat (60 degree C for 30min), or both and then vacuum-packaged to 2kPa for up to 10d storage at 37 degree C, 25 degree C, or 4 degree C. Storage at 37 degree C resulted in increases in viable counts after 1 d to over 7 log10cfu/g beef, whereas storage at 4 degree C prevented spore germination and growth for all treatments. At 25 degree C, heat-treated beef samples reached 6 log10cfu/g viable counts in 2d and spores/vegetative cells on control or ozone-treated samples did not germinate or grow through the first day of vacuum-packaged storage. Modified atmospheres with increasing CO2 concentration were also compared with regard to bacterial survival during beef storage at 25 degree C. C. perfringens spores remained dormant in control and ozone-treated beef during a 10-d storage at 25 degree C. Pretreatment with heat increased germination and outgrowth during storage of beef, whereas ozone treatment and no treatment controls were effective in inhibiting spore germination and outgrowth in combination with increasing CO2 concentrations above 30% or refrigeration. These data support the avoidance of heat in the pretreatment of raw beef.

Our objectives were to (1) determine if in vitro variations translate to differences in resistance to Salmonella enteritidis (SE) and (2) quantitate cytokine mRNA in heterophils from SE-infected chicks. One-day-old chicks were challenged and organs were cultured for SE. Chicks with efficient heterophils (A and D) were less susceptible to SE compared to chicks with inefficient heterophils (B and C). Heterophils were isolated from SE-infected chicks and cytokine mRNA expression was evaluated using quantitative real-time RT-PCR. Pro-inflammatory cytokine mRNA was up-regulated in heterophils from SE-resistant chicks compared to susceptible chicks. This is the first report to quantitate cytokine mRNA in heterophils from SE-infected chicks. These data show a relationship between in vitro heterophil function, increased pro-inflammatory cytokine mRNA expression, and increased resistance to SE in 1-day-old chicks.

Representative isolates were also directly compared with six previously identified races on eight chickpea genotypes. Many of the chickpea differentials reacted similarly to inoculation with each isolate of D. rabiei, and several previously identified races caused similar levels of disease on the differentials. This indicates that the number of differentials can be reduced significantly without sacrificing accuracy in describing pathogenic variation of D. rabiei on chickpea. Pathogenic variation among samples of US isolates allowed classification of the isolates into two pathotypes. The distribution of disease phenotypes of the 48 germplasm lines was bimodal after inoculation with pathotype I isolates, whereas the distribution of disease phenotypes was continuous after inoculation with pathotype II isolates. Such distinct distribution patterns suggest that chickpea plants employ different resistance mechanisms to each pathotype and that the two pathotypes may have different genetic mechanisms controlling pathogenicity. The advantages of using the two-pathotype system in assaying pathogenicity of the pathogen and in studying resistance mechanisms of the host are discussed. Three chickpea accessions, PI 559361, PI 559363 and W6 22589, showed a high level of resistance to both pathotypes, and can be employed as resistance sources in chickpea breeding programmes for resistance to ascochyta blight.

Where intensive forestry practices have eliminated much of the natural understory of the longleaf ecosystem, the potential for reestablishment through a seed bank may present a valuable restoration opportunity. Longleaf pine sites converted to loblolly pine plantations and non-disturbed longleaf sites on the Coastal Plain of North Carolina were examined for seed bank presence and diversity. Conducting vegetation surveys and examining the seed bank using the seedling emergence technique allowed for verification of the seed bank presence, as well as evaluation of the quality of the seed bank on disturbed longleaf pine sites. Forty-three species and over 1,000 individuals germinated, and the seed banks of both the disturbed and non-disturbed stand types contained species not noted in the vegetation survey. Although many of these species were considered weedy and typical of disturbance, numerous taxa were indicative of stable longleaf pine communities. This study confirms both the presence and quality of seed banks in highly disturbed former longleaf pine sites, suggesting that the seed bank may be an important tool in restoration efforts.

Once initial host barrier systems have been breached by these pathogens, the innate immune system provides the next level of defense against these infectious agents. The innate immune response is characterized by the induction of proinflammatory cytokines, as well as increases in other accessory proteins that facilitate host recognition and elimination of the pathogens. The objective of the current study was to characterize the innate immune response during clinical mastitis elicited by these two important, yet less well-studied, Gram-positive and Gram-negative organisms. The pro-inflammatory cytokine response and changes in the levels of the innate immune accessory recognition proteins, soluble CD14 (sCD14) and lipopolysaccharide (LPS)-binding protein (LBP), were studied. Decreased milk output, induction of a febrile response, and increased acute phase synthesis of LBP were all characteristic of the systemic response to intramammary infection with either organism. Infection with either bacteria similarly resulted in increased milk levels of IL-1 beta , IL-8, IL-10, IL-12, IFN- gamma , TNF- alpha , sCD14, LBP, and the complement component, C5a. However, the duration of and/or maximal changes in the increased levels of these inflammatory markers were significantly different for several of the inflammatory parameters assayed. In particular, S. uberis infection was characterized by the sustained elevation of higher milk levels of IL-1 beta , IL-10, IL-12, IFN- gamma , and C5a, relative to S. marcescens infection. Together, these data demonstrate the variability of the innate immune response to two distinct mastitis pathogens.

In contrast, the disease rarely occurs on tobacco in Georgia and Florida, although bacterial wilt is a common problem on tomato. We investigated whether this difference in disease incidence could be explained by qualitative characteristics of avirulence gene avrA in the R. solanacearum population in the southeastern United States. Sequence analysis established that wild-type avrA has a 792-bp open reading frame. Polymerase chain reaction (PCR) amplification of avrA from 139 R. solanacearum strains generated either 792-bp or approximately 960-bp DNA fragments. Strains that elicited a hypersensitive reaction (HR) on tobacco contained the 792-bp allele, and were pathogenic on tomato and avirulent on tobacco. All HR-negative strains generated a approximately 960-bp DNA fragment, and wilted both tomato and tobacco. The DNA sequence of avrA in six HR-negative strains revealed the presence of one of two putative miniature inverted-repeat transposable elements (MITEs): a 152-bp MITE between nucleotides 542 and 543, or a 170-bp MITE between nucleotides 461 and 462 or 574 and 575. Southern analysis suggested that the 170-bp MITE is unique to strains from the southeastern United States and the Caribbean. Mutated avrA alleles were present in strains from 96 and 75% of North and South Carolina sites, respectively, and only in 13 and 0% of the sites in Georgia and Florida, respectively. Introduction of the wild-type allele on a plasmid into four HR-negative strains reduced their virulence on both tobacco and tomato. Inactivation of avrA in an HR-positive, avirulent strain, resulted in a mutant that was weakly virulent on tobacco. Thus, the incidence of bacterial wilt of tobacco in the southeastern United States is partially explained by which avrA allele dominates the local R. solanacearum population.

As a result, interest in and research on invasive plant species in wildland settings has accelerated. Nonetheless, the ecological and economic impacts of non-native species continue to grow, raising the question of how to best apply science to the regulation and management of invasive plants. A major constraint to controlling the flow of potentially undesirable plant species is the lack of a strong regulatory framework concurrent with increases in trade volume. To address this, ecologists have been developing models to predict which species will be harmful to wildland values and are working with the horticultural industry to apply this information to the sale of species. The management of established invasive plants is hampered by conflicting goals, a lack of information on management outcomes, and a lack of funding. Ecologists and weed scientists can provide a scientific basis for prioritizing species for control and for managing species composition through the application of control technology, which can take place simultaneously with the manipulation of the ecological processes that influence community susceptibility to invasion. A stronger scientific basis for land management decisions is needed and can be met through nationally funded partnerships between university and agency scientists and land managers.

Material was placed out and mating disruption was commenced at the beginning of April in the first year, and at the beginning of July the second year. This technique effectively prevented males from finding females in female-baited traps placed throughout the plot. Navel orangeworm abundance was high in figs during the first and third flight, but lower in June and July during the second flight. Since Calimyrna figs are not susceptible to attack by navel orangeworm until mid-to-late July, these findings suggest that materials cost can be reduced by beginning treatment later. Implications for insect pest management in figs and other California crops are discussed.

Integrated cotton (Gossypium hirsutum) cropping and livestock production systems in West Texas may provide more sustainable alternatives to the traditional continuous cotton system and improve soil quality. Our study was conducted on a Pullman soil (Fine, mixed, thermic Torrertic Paleustolls) after 5 yr as a complete randomized block design (three replications) that compared continuous cotton and an integrated livestock-crop system with a perennial warm-season grass pasture (Bothriochloa bladhii) paddock and two paddocks (two stages) of a rotation (wheat [Triticum aestivum]-fallow-rye [Secale cereale]-cotton). Total N (average: 1.0 g kg super(-1) soil) remained similar among systems and soil pH was >8.1. Organic C was higher (13.5 g kg super(-1) soil) in perennial pasture compared with continuous cotton (9.0 g kg super(-1) soil) at 0 to 5 cm. A similar trend was found for the soil aggregate stability. Soil microbial biomass C (C sub(mic)) was greater in perennial pasture (193 mg kg super(-1) soil) and the rotation under rye and cotton (237 mg kg super(-1) soil) compared with continuous cotton (124 mg kg super(-1) soil) at 0 to 5 cm, and in perennial pasture at 5 to 10 and 10 to 15 cm. Soil microbial biomass N (N sub(mic)) showed similar trends. Soil enzyme activities were greater in perennial pasture and the rotation (under rye and cotton) than under continuous cotton at 0 to 5 cm. The integrated crop-livestock system had higher protozoa (20:4 omega 6c = 1.98%) and fungi (18:3 omega 9c = 1.30%) than continuous cotton (20:4 omega 6c = 1.09%; 18:3 omega 9c = 0.76%). These findings suggest positive differences in soil function and sustainability of the integrated crop-livestock system compared with continuous cotton.

The C. jejuni isolate F38011 lpxA gene, encoding a UDP-N-acetylglucosamine acyltransferase, was identified by sequence analysis of an expression plasmid that restored wild-type lipopolysaccharide levels in Escherichia coli strain SM105 [lpxA(Ts)]. With oligonucleotide primers developed to the C. jejuni lpxA gene, nearly full-length lpxA amplicons were amplified from an additional 11 isolates of C. jejuni, 20 isolates of C. coli, 16 isolates of C. lari, and five isolates of C. upsaliensis. The nucleotide sequence of each amplicon was determined, and sequence alignment revealed a high level of species discrimination. Oligonucleotide primers were constructed to exploit species differences, and a multiplex PCR assay was developed to positively identify isolates of C. coli, C. jejuni, C. lari, and C. upsaliensis. We characterized an additional set of 41 thermotolerant isolates by partial nucleotide sequence analysis to further demonstrate the uniqueness of each species-specific region. The multiplex PCR assay was validated with 105 genetically defined isolates of C. coli, C. jejuni, C. lari, and C. upsaliensis, 34 strains representing 12 additional Campylobacter species, and 24 strains representing 19 non- Campylobacter species. Application of the multiplex PCR method to whole-cell lysates obtained from 108 clinical and environmental thermotolerant Campylobacter isolates resulted in 100% correlation with biochemical typing methods.

We compared the pollination system with reproductive success in this species through controlled, hand-pollination experiments. Ovaries of flowers sampled from unbagged inflorescences were visited by pollen-eating flies (primarily members of the family Syrphidae), beetles (primarily Cosmosalia and Epicauta spp.), and small bees, and produced normal-sized capsules and mature seeds. Ovaries of flowers from inflorescences bagged to prevent insect pollination produced small capsules containing undeveloped or no seeds. Epifluorescence analyses suggest that 0.95 of the uncovered flowers are cross- pollinated by insects with pollen tubes penetrating style and ovary tissue. Flowers show a "leaky" but early-acting self-incompatibility system. While hundreds of pollen tubes germinate on each stigmatic surface following self- pollination, few pollen tubes penetrate the stigmatic surface and none penetrate the ovary. In contrast, when stigmas are cross-pollinated by hand with pollen from a second inflorescence pollen tubes were seen penetrating style and ovary. Self-incompatibility in X. tenax parallels that of some species of Trillium, a sister genus within the Melanthiaceae.

Fecal samples collected from swine operations from 13 of the top 17 swine-producing states were tested for the presence of STEC. After enrichment of swine fecal samples in tryptic soy broth, the samples were tested for the presence of stx sub(1) and stx sub(2) by use of the TaqMan E. coli STX1 and STX2 PCR assays. Enrichments of samples positive for stx sub(1) and/or stx sub(2) were plated, and colony hybridization was performed using digoxigenin-labeled probes complementary to the stx sub(1) and stx sub(2) genes. Positive colonies were picked and confirmed by PCR for the presence of the stx sub(1), stx sub(2), or stx sub(2e) genes, and the isolates were serotyped. Out of 687 fecal samples tested using the TaqMan assays, 70% (484 of 687) were positive for Shiga toxin genes, and 54% (370 of 687), 64% (436 of 687), and 38% (261 of 687) were positive for stx sub(1), stx sub(2), and both toxin genes, respectively. Out of 219 isolates that were characterized, 29 (13%) produced stx sub(1), 14 (6%) produced stx sub(2), and 176 (80%) produced stx sub(2e). Twenty-three fecal samples contained at least two STEC strains that had different serotypes but that had the same toxin genes or included a strain that possessed stx sub(1) in addition to a strain that possessed stx sub(2) or stx sub(2e). The STEC isolates belonged to various serogroups, including O2, O5, O7, O8, O9, OX10, O11, O15, OX18, O20, O57, O65, O68, O69, O78, O91, O96, O100, O101, O120, O121, O152, O159, O160, O163, and O untypeable. It is noteworthy that no isolates of serogroup O157 were recovered. Results of this study indicate that swine in the United States harbor STEC that can potentially cause human illness.

Graft inoculation of the indicator host, Ipomoea setosa, is the accepted detection method for these viruses, but the assay is laborious and requires up to 8 weeks. When infected sweetpotato is subjected to meristem tip culture to eliminate these viruses, the eradication rate is low. In this study, a polymerase chain reaction (PCR) detection assay was developed for the detection of geminiviruses in a variety of sweetpotato cultivars. Different methods were evaluated to extract nucleic acids suitable for PCR from Ipomoea spp., and a reliable and simple extraction method was developed for large-scale sample preparation. PCR products of the expected sizes were amplified from infected plants using degenerate and virus-specific primers, but not from noninoculated indicator plants. PCR assays using three primer pairs detected nine uncharacterized isolates of the geminiviruses in sweetpotato from Asia and America. However, the best PCR result was obtained with degenerate primers SPG1/SPG2, which detected a Taiwan isolate of Sweet potato leaf curl virus (SPLCV-Taiwan) in a sample diluted to 10 super(-9). Viral identities of three amplicons from SPLCV-Taiwan were confirmed by sequencing. The degenerate primers had a broader detection range than virus-specific primers; therefore, they were used to detect geminiviruses in in vitro plantlets and greenhouse-grown sweetpotato plants, and in several Ipomoea hosts. PCR was shown to be as reliable for virus detection as grafting.

Corn-cotton rotations are common in South Texas, where reduced tillage frequently results in long-term residence of corncobs on soil surfaces. Corncobs are colonized by A. flavus either prior to harvest or while in the soil. This study sought to determine the potential of corncobs as sources of inoculum for cotton and corn in South Texas. A. flavus communities in corncob and soil samples were collected during the planting seasons of 2001 to 2003 from 29 fields extending from Calhoun and Victoria Counties in the north to the Rio Grande Valley. In order to assess persistence of A. flavus in corncobs, A. flavus communities in corncobs and soil were contrasted every 2 to 3 months in four fields throughout the 3-year study. To assess seasonal variation, similar contrasts were performed in two fields on a biweekly basis. The results indicate that corncobs are major sources of A. flavus inoculum. Corncobs from the previous season contained, on average, over 190 times more A. flavus propagules than soil from the same field, and 2-year-old corncobs still retained 45 times more propagules than soil. There was no significant difference in the incidence of A. flavus strain S on corncobs and soil. The quantity of A. flavus in corncobs decreased with corncob age (r super(2) = 0.54; P = 0.002).

In our studies, a Gram-negative, facultative anaerobic, rod-shaped bacterium was consistently isolated from decayed as well as symptomless ginger rhizomes. The bacterium was identified as Enterobacter cloacae by biochemical assays and 16S rDNA sequence analysis. Rot symptoms, which usually occurred in the central cylinder of the rhizome, were characterized by yellowish-brown to brown discolored tissue and firm to spongy texture. In inoculation experiments, ginger strains of E. cloacae produced basal stem and root rot, with foliar chlorosis and necrosis in tissue-cultured ginger plantlets, and discolored and spongy tissue in mature ginger rhizome slices and whole segments. In other hosts, ginger strains of E. cloacae caused internal yellowing of ripe papaya fruit and internal rot of onion bulbs. All strains that caused symptoms in inoculated plants were reisolated and identified as E. cloacae. Our studies suggest that E. cloacae can exist as an endophyte of ginger rhizomes, and under conditions that are favorable for bacterial growth, or host susceptibility, including maturity of tissues, rhizome rot may occur. Rhizome quality may be impacted by the presence of E. cloacae under conditions such as high temperature, high relative humidity, and low oxygen atmosphere that may affect the development of decay, and such conditions should be avoided during post-harvest handling and storage. The association of E. cloacae with a rhizome rot of ginger is a new finding.

Therefore, the effects of refrigeration at 4 degree C, freezing at -20 degree C, and a combination of refrigeration and freezing on the survival of C. jejuni in ground chicken and on chicken skin were examined. Samples were enumerated using tryptic soy agar containing sheep's blood and modified cefoperazone charcoal deoxycholate agar. Refrigerated storage alone for 3 to 7 days produced a reduction in cell counts of 0.34 to 0.81 log sub(10) CFU/g in ground chicken and a reduction in cell counts of 0.31 to 0.63 log sub(10) CFU/g on chicken skin. Declines were comparable for each sample type using either plating medium. Frozen storage, alone and with prerefrigeration, produced a reduction in cell counts of 0.56 to 1.57 log sub(10) CFU/g in ground chicken and a reduction in cell counts of 1.38 to 3.39 log sub(10) CFU/g on chicken skin over a 2-week period. The recovery of C. jejuni following freezing was similar on both plating media. The survival following frozen storage was greater in ground chicken than on chicken skin with or without prerefrigeration. Cell counts after freezing were lower on chicken skin samples that had been prerefrigerated for 7 days than in those that had been prerefrigerated for 0, 1, or 3 days. This was not observed for ground chicken samples, possibly due to their composition. C. jejuni survived storage at 4 and -20 degree C with either sample type. This study indicates that, individually or in combination, refrigeration and freezing are not a substitute for safe handling and proper cooking of poultry.

Inspection and quarantine procedures have eradicated reinfestations successfully within the US, but increasing acaricide resistance in Mexican B. microplus populations poses a threat to future eradication efforts. Better understanding of interrelationships among Boophilus populations, their hosts, and vegetation communities in south Texas could improve prediction of the behavior of reintroduced Boophilus populations and increase management options. To this end, we constructed a simulation model to evaluate how microclimate, habitat (i.e. vegetation) heterogeneity, and within-pasture cattle movement may influence dynamics of Boophilus ticks in south Texas. Unlike previous Boophilus tick models, this model simulates dynamics at an hourly time-step, calculates all off-host dynamics as functions of temperature and relative humidity, and runs with ground-level microclimate data collected bi-hourly in three different habitat types. Sensitivity analysis of the model showed that temperatures and relative humidities created by habitat type, as well as engorged female mass, influenced tick population dynamics most strongly. Host habitat selection, initial number of larvae per cow, and the number of cells into which the simulated pasture was divided also had a strong influence. Population dynamics appeared moderately sensitive to the proportion of Bos indicus in cattle genotypes and the larval attachment rate, while appearing relatively insensitive to factors such as mortality rate of engorged females. When used to simulate laboratory experiments from the literature, the model predicted most observed life-history characteristics fairly well; however, it tended to underestimate oviposition duration, incubation duration, and egg mortality and overestimate larval longevity, especially at low temperatures and high humidities. Use of the model to predict Boophilus population dynamics in hypothetical south Texas pastures showed that it reasonably generated qualitative patterns of stage-wise abundances but tended to overestimate on-host tick burdens. Collection and incorporation of data that appear not to exist for Boophilus ticks, such as larval lipid content and lipid-use rates, may improve model accuracy. Though this model needs refinements such as a smaller spatial resolution, it provides insight into responses of B. microplus or B. annulatus populations to specific weather patterns, habitat heterogeneity, and host movement.

In the Norwegian experiment, the offspring of early-spawning fish, which had larger eggs and emerged a few days before offspring of later spawning fish, had consistently higher survival rates. In the U.S.A. experiment, stream sections with higher proportions of favorable foraging locations during the critical period (the transition from dependence on maternally-derived yolk reserves to independent feeding) had lower loss rates of fish stocked as unfed fry. These results provide support for the critical period concept (CPC) in Atlantic salmon, underscores the utility of a manipulative approach to achieve further advances in knowledge of Atlantic salmon ecology and provide additional guidance to management and restoration. A mechanistic, conceptual model for density dependence is presented to identify important knowledge gaps that remain to further evaluate the importance of the CPC for Atlantic salmon population regulation.

Forest restoration activities over the past decade, however, have driven recent changes in land use through an intensified afforestation effort on former agricultural land. This intense afforestation effort, particularly in the Lower Mississippi Alluvial Valley, has generated a demand for alternative afforestation systems that accommodate various landowner objectives through restoration of sustainable forests. We are currently studying an afforestation system that involves initial establishment of the rapidly growing native species eastern cottonwood (Populus deltoides Bartr. ex Marsh.), followed by enrichment of the plantation understory with Nuttall oak (Quercus nuttallii Palm.). In this article, we examine the growth and biomass accumulation by Nuttall oak seedlings to determine whether this species can be established and whether it will develop beneath the cottonwood overstory. After 3 years of growth beneath cottonwood canopies, Nuttall oak seedlings were similar in height (126 cm), but were 20% smaller in root-collar diameter than seedlings established in open fields. Seedlings established in the open accumulated more than twice the biomass of seedlings growing beneath a cottonwood canopy. However, the relative distribution of accumulated biomass in seedlings did not differ in the two environments. Ten percent of total seedling biomass was maintained in leaf tissue, 42% was maintained in stem tissue, and 48% was maintained in root tissue on open-grown seedlings and seedlings established in the understory of cottonwood plantations. Though establishment in the more shaded understory environment reduced Nuttall oak growth, seedling function was not limited enough to induce changes in plant morphology. Our results suggest that an afforestation system involving rapid establishment of forest cover with a quick-growing plantation species, followed by understory enrichment with species of later succession, may provide an alternative method of forest restoration on bottomland hardwood sites and perhaps other sites degraded by agriculture throughout temperate regions.

Small mammals were live-trapped in recently clearcut stands that retained pine corridors 100m in width and in adjacent pine plantations, 20-23-years-old. We compared small mammal communities between harvested stands with corridors and non-harvested pine stands. We captured 1158 small mammals, representing 844 unique individuals and seven different species in 94,080 trap nights. Rodent abundance, richness, and diversity indices were greater in harvested stands with corridors than in non-harvested pine stands. The early successional habitat created by clearcutting was used by many small mammal species, including cotton rats (Sigmodon hispidus) and marsh rice rats (Oryzomys palustris). Species composition of small mammals within the corridor habitats was similar to that in the non-harvested pine stands. The inclusion of corridors in pine plantation management enhances habitat diversity and ecosystem maintenance and contributes to local diversity of the small mammal community.

An increasingly common approach to the restoration of habitats of endangered salmon in the Columbia Basin of the Pacific Northwest (USA) is to exclude livestock from streamside communities. Yet, few studies have examined how ending livestock grazing changes ecosystem properties and belowground processes in herbaceous-dominated riparian plant communities (meadows). Along the Middle Fork John Day River, Oregon, we compared ecosystem properties of dry (grass and forb-dominated) and wet (sedge-dominated) meadow communities at three sites that had been managed for sustainable livestock production with three sites where livestock had been excluded for 9-18 years as a means of riparian and stream restoration. Profound differences in the belowground properties of grazed and exclosed communities were measured. In dry meadows, total belowground biomass (TBGB consisting of roots and rhizomes) was similar to 50% greater in exclosures (1105 and 1652 g/m super(2) in the grazed and exclosed sites, respectively). In exclosed wet meadows, the TBGB was 62% greater than in the grazed sites (1761 and 2857 g/m super(2), respectively). Soil bulk density was significantly lower, and soil pore space was higher in exclosed sites of both meadow types. The mean infiltration rate in exclosed dry meadows was similar to 13-fold greater than in grazed dry meadows (142 vs. 11 cm/h), and in wet meadows the mean infiltration rate in exclosures was 233% greater than in grazed sites (24 vs. 80 cm/h). In exclosed wet meadows, the rate of net potential nitrification was 149-fold greater (0.747 vs. 0.005 mu g NO sub(3)-N times [g soil] super(-1) times d super(-1)), and the rate of net potential mineralization was 32-fold greater (0.886 vs. 0.027 mu g N times [g soil] super(-1) times d super(-1), respectively) when compared to grazed sites, though changes observed in dry meadows were not significant. Livestock removal was found to be an effective approach to ecological restoration, resulting in significant changes in soil, hydrological, and vegetation properties that, at landscape scales, would likely have great effects on stream channel structure, water quality, and the aquatic biota.

The same combinatorial strategies could be applied to a broad spectrum of areas in agricultural and food research, including food safety and nutrition, development of product ingredients, and processing and conversion of natural products. In contrast to "rational design", the combinatorial approach relies on molecular diversity and high-throughput screening. The capability of exploring the structural and functional limits of a vast population of diverse chemical and biochemical molecules makes it possible to expedite the creation and isolation of compounds of desirable and useful properties. Several studies in recent years have demonstrated the utility of combinatorial methods for food research. These include the discovery of synthetic antimicrobial, antioxidative, and aflatoxin-binding peptides, the identification and analysis of unique flavor compounds, the generation of new enzyme inhibitors, the development of therapeutic antibodies for botulinum neurotoxins, the synthesis of unnatural polyketides and carotenoids, and the modification of food enzymes with novel properties. The results of such activities could open a large area of applications with potential benefits to the food industry. This review describes the current techniques of combinatorial chemistry and their applications, with emphasis on examples in food science research.

One procedure is called the slope-projection method, and the other is called a covariance procedure. Field tests were conducted with full-season, narrow-row cotton (Gossypium hirsutum L.) on a well-drained, sandy soil in a semiarid environment over a 5-year period. The goal was to improve automated irrigation scheduling, by relating evapotranspiration (ET) to growing degree days (GDD). The result, using a Penman-Monteith reference ET, was an average midseason crop coefficient of 1.11, with a standard error of 0.056. With class A pan evaporation as the reference ET, the average midseason crop coefficient was 0.877, with a standard error of 0.029. A fifth-order polynomial for the pan-based crop coefficient as a function of GDD was programmed into a controller and used successfully to irrigate a field automatically for one season.

We investigated whether insect herbivory differs from a general wound response, and if so, is the induction specific to the pest/host plant interaction? Herbivory by beet armyworm (BAW; Spodoptera exigua) caterpillars on maize results in a unique pattern of volatile compounds not triggered by wounding alone that attracts the generalist parasitoid Cotesia marginiventris. Caterpillar-induced volatile emission can be mimicked when a component of the BAW oral secretions (N-(17-hydroxylinolenoyl)-l-glutamine) termed volicitin, is applied to wounded leaves. We identified genes that are affected by BAW feeding by comparing volicitin treatment with wounding alone. We compared cDNAs from these two populations by isolating genes from a subtractive library and using reverse northerns. Virtual northern blots confirmed these results and further showed that BAW infestation affected the expression of these genes. In some cases, BAW feeding inhibited the expression of volicitin-induced genes, suggesting the role of additional bioactive components in caterpillar regurgitate. Transcripts involved in volatile production are increased by volicitin and BAW infestation treatments, and are also detectable at low levels in mechanically wounded leaves. Finally, we identified three new sesquiterpene cyclase genes that are induced by volicitin.

Radiotracer studies with super(14)C-acetate demonstrate that feeding on host phloem stimulates biosynthesis in males of three Ips spp. However, treatment with juvenile hormone III (JH III) stimulates biosynthesis only in Ips pini. Thus, two species in the grandicollis subgeneric group (I. grandicollis and I. paraconfusus) appear to have a different mode of regulation related to JH III than does I. pini. Between 16 and 20 hr after feeding has commenced, pheromone production, as measured by accumulation in abdominal tissue, is stimulated about 150- (I. pini) and 350-times (I. paraconfusus) above the control level of 1-10 ng/male measured at 0 hr. Treatment with JH III results in accumulation in I. pini that is 3-4 times more than in phloem-fed males, whereas the identical treatment results in only weak accumulation in I. paraconfusus (45-times less than phloem-fed males). Comparative studies of gene expression and enzyme activity related to biosynthesis also support different modes of JH III-related regulation in I. pini and I. paraconfusus. In males of both species, feeding on host phloem results in increased transcript abundance and increased activity for the key de novo isoprenoid pathway enzyme 3-hydroxy-3-methylglutaryl-CoA reductase (HMG-R). However, while JH III treatment results in comparable maximal increases in HMG-R transcript levels in both species (similar to feeding), the activity of HMG-R in crude extracts from JH III-treated male I. paraconfusus is low in comparison with male I. pini. Hypothetical explanations for the interspecific dichotomy in the regulation of pheromone biosynthesis include a second hormone or factor in grandicollis group species that functions either alone or with JH III; in both cases acting after HMG-R has been transcribed.

In termites, cuticular hydrocarbons (CHCs) have been extensively studied for their role in nestmate recognition and aggressive discrimination of nonnest-mates. More recently, molecular genetic techniques have made it possible to determine relatedness between colonies and to investigate the influence of genetics on aggression. In the Formosan subterranean termite, Coptotermes formosanus, however, the role of CHCs and genetic relatedness in inter-colony aggression has been ambiguous, suggesting the involvement of additional factors in nest-mate recognition. In this study we assess the range of aggression in this termite species and characterize the influence of genetic relatedness, CHC profiles and diet on aggression levels. We collected four colonies of C. formosanus, feeding either on bald cypress or birch, from three locations in Louisiana. Inter-colony aggression ranged from low to high. Differences in CHC profiles, as well as genetic distances between colonies determined by using microsatellite DNA markers, showed no significant correlation with aggression. However, termite diet (host tree) played a significant role in determining the level of aggression. Thus, two distantly related colonies, each feeding on different diets, showed high aggression that significantly diminished if they were fed on the same wood in the laboratory (spruce). Using headspace solid phase microextraction, we found three compounds from workers fed on birch that were absent in workers fed on spruce. Such diet-derived chemicals may be involved in the complex determination of nest-mate recognition in C. formosanus.

I used four sets of census field data, and developed an idealized space-time dynamic system, to study the behavior of spatial autocorrelation estimates when a practical method of sampling is employed. Estimates were made using both a classical geostatistical approach and a recently developed non-parametric approach. In field data, the estimate of the local spatial autocorrelation (i.e. autocorrelation as the distance between pairs of sampling points approaches 0), was greatly affected by sample size, while the range of spatial dependence (i.e. the distance at which the autocorrelation becomes negligible) was fairly stable. Similar patterns were seen in the theoretical system, as well as greater variability in local spatial autocorrelation during the invasion stage of colonization. When sampling for the purposes of quantifying spatial patterns, improved estimates of spatial autocorrelation may be obtained by increasing the number of pairs of points that are close in space at the expense of attempting to cover the entire region of interest with equidistant sampling points. Also, results from the theoretical space-time system suggested that greater resolution in sampling may be required in newly establishing populations relative to those already established.

An experimental field site was established to determine drainage water loss from pot-in-pot container nurseries with micro-irrigation. The site consisted of 50 container-grown trees, 10 tipping-bucket rain gauge units, and a portable weather station. Rain gauge units were calibrated four different ways to determine repeatability and reliability for real-time measurement of the drainage water. Volume of water was calculated from the product of number of tips and volume per tip. Accuracy of measurements was verified by the amount of drainage water collected weekly in collection buckets located under rain gauge units for various irrigation applications and rainfall events. The maximum difference in the weekly amount of drainage water collected with the collection buckets and measured with the rain gauge units was 1.215 L (or 5.3% error) when the daily irrigation application to five trees was 15.5 L. The system reported real-time measurement of drainage water due to irrigation and rainfall, and provided a research tool to evaluate strategies for nurseries to better manage irrigation schedules.

Non-irrigated, cereal and oilseed growers who participated in biennial field tours (1996-2000) were mailed a self-administered questionnaire, which asked about: (1) their interest, use and adoption of technology developed or demonstrated in the project: (2) their opinions about the project's collaborators, planning and design; and (3) their overall impressions of the project. One hundred and one eligible growers responded to the questionnaire, for a 55% overall response rate and a 62% completion rate. Survey results confirmed that the Ralston Project field tours were a successful means of technology transfer among participants. Seventy-seven percent of growers found one or more project technologies particularly useful to their own production operation(s). More than 60% conducted independent trials with one or more technologies, with 50% of these trials resulting in permanent adoptions. The project's planning and design had a more positive effect on growers' opinion of the project than the type of collaborations and sources of funding. Specific strategies that had a substantially positive effect on growers' opinions included: (1) the project's 'whole system' treatment design; (2) use of large plots to accommodate field-sized equipment; and (3) collaboration among scientific disciplines and with local growers. Seven variables known to influence the adoption of innovation were also tested against growers' decisions to try any of the project's technology in their own farm operations. Personal character variables influenced individuals' decisions to try project technology more so than environmental conditions. Level of education, previous adoption behavior and average annual rainfall significantly influenced growers' behavior (P < 0.05). Our survey population consisted of early users of conservation-based farming technology, primarily innovators and early adopters. The Ralston Project made the greatest impact on current adopters and users of conservation-based farming technology. Interest among non-users was also high enough to suggest that the Ralston Project contributed positively to the diffusion of conservation cropping systems and associated technology into the greater grower community. We discovered from this survey that the planning and execution of field research plays a significant and influential role in transferring more complex, and perhaps high-risk, conservation-based farm technology. By understanding how research and field design affect different user groups within the grower community, professionals can identify appropriate strategies to expand interest beyond their primary target audience and influence attitudes and behaviors that facilitate widespread adoption.

Land-use shifts occur because of relative changes in land rents, which are determined in part by financial returns in commodity markets. In recent decades, more than 3 million ac shifted annually in or out of US forest use. Gross amounts of land-use change are an order of magnitude larger than net changes. Between 1982 and 1997, a net amount of 3.6 million ac was added to the US nonfederal forest land base. Area of developed uses is projected to increase by about 70 million ac by 2030, with the largest percentage diverted from forests. All regions show substantial increases in developed area, with increases in population and personal income as key drivers. Forest area is projected to decline in two key timber supply regions, the South (-6.0 million ac) and the Pacific Northwest Westside (-1.9 million ac). Other regions having projected losses in forest area include the Northeast (-3.0 million ac), the Lake States (-1.2 million ac), and the Pacific Southwest (-0.6 million ac). Conditions in land markets reflect increased rents from residential and other uses of developed land, such that forests and forestland values will increasingly be influenced by development and its location.

Intensification of farming systems has resulted in local accumulations of P in some agricultural watersheds with related increases in P runoff. In most cases, continual land application of manure at rates exceeding crop P removal is the proximate cause of P runoff. To mitigate associated water quality impairments, P-based agricultural best management practices (BMPs) are now becoming a part of farm nutrient planning. This planning involves the selection, timing, and implementation of source and transport BMPs at field, farm, and watershed scales. Source measures include balancing P imports and exports, improved livestock feed management, chemical and physical treatment of manures, appropriate rate, method, and timing of land application based upon regular soil and manure testing, adequate manure storage and transport infrastructure, and composting. Transport measures aim to reduce runoff and erosion via practices such as conservation tillage, contour ploughing, and vegetative filter strips. To be effective, these measures must be carefully selected and targeted to areas at greatest risk to P loss. This vulnerability can be identified and ranked by P indices, which account for source and transport factors controlling P loss. We demonstrate that the P Index can provide flexible yet reliable manure management and provide farmers with options to minimise the risk of P loss from several farms in Pennsylvania, United States. Overall, a comprehensive and holistic approach to manure management can decrease P transfers from land to water.

Additionally, cost implications of establishing and maintaining environmentally effective BMPs are often a crucial factor in selecting and adopting BMPs. This article considers both water quality and economic concerns and presents a methodology developed for determining cost-effective farm- or watershed-level scenarios through optimization. This optimization technique uniquely incorporates three existing tools: a genetic algorithm (GA), a watershed-level nonpoint-source model (Soil and Water Assessment Tool, SWAT), and a BMP tool. The GA combines initial pollutant loadings from SWAT with literature-based pollution reduction efficiencies from the BMP tool and with BMP costs to determine cost-effective watershed scenarios. The methodology was successfully applied to a 300 ha farm within the Cannonsville Reservoir watershed, a phosphorus (P) restricted reservoir within New York City's water supply system. An average reduction in dissolved P of 60% over the lifetime of the BMPs was set as the pollutant target. A baseline scenario was established to represent practices on the farm before BMP implementation. The most cost-effective scenario for the farm, under the presented methodology, achieved a cost-effectiveness of 0.6 kg dissolved P reduction per dollar spent per year. Additionally, the methodology determined alternative scenarios for the farm, which met the pollution reduction criterion cost-effectively. The methodology, as developed, is extendable to multi-farm or watershed-level evaluations.

Declining input use, soil fertility and inefficient chemical pest controls are contributing factors. We evaluate the potential impact of Bt cotton on WCA using a multiregion general equilibrium model and multicountry estimates of Bt-induced productivity. We find that Bt cotton raises growers' returns, land value and welfare. Released labor from cotton is shifted to food crops hence reducing labor shortage constraints. Overall, results indicate that potential gross benefits from Bt cotton are substantial for WCA cotton sector, and that the economic costs of nonadoption are equally significant.

We evaluated three technologies for enhancing nitrification of pig lagoon wastewater prior to denitrification: overland flow, trickling filter, and a bioreactor using nitrifying pellets. The overland flow system consisted of a 4 x 20-m plot with 2% slope with a subsurface impermeable barrier receiving a total N loading rate of 64-99 kg N ha super(-1) day super(-1). Total N removal efficiency ranged from 36 to 42%, and 7% of the total N application was recovered in the effluent as nitrate. The trickling filter consisted of a 1-m super(3) tank filled with marl gravel media which supported a nitrifying biofilm. Lagoon wastewater was applied as a fine spray on the surface at hydraulic loading rates of 684 litres m super(-3) day super(-1) and total N loading rates of 249 g m super(-3) day super(-1). The media filter treatment transformed up to 57% of the inflow total N into nitrate when wastewater was supplemented with lime. The nitrifying pellets technology used acclimated nitrifying cells immobilised in 3-5 mm polymer pellets. Pig wastewater was treated in an aerated fluidised reactor unit with a 15% (w/v) pellet concentration. Nitrification efficiencies of more than 90% were obtained in continuous flow treatment using total N loading rates of 438 g N m super(-3) day super(-1) and hydraulic residence time of 12 h. Two conclusions are suggested from this research: (1) that substantial nitrification of pig lagoon wastewater can be attained particularly using aerobic treatments with enriched nitrifying populations, and (2) that large mass removal of N from pig wastewater may be possible by sequencing nitrification and denitrification unit processes.

K sub(i) values were accumulated from peer-reviewed literature searched via PubMed. The 3D structure files of target proteins were originally from Protein Data Bank (PDB), while the 2D structure files of the chemicals were collected together with the K sub(i) values and then converted into 3D ones. In KiBank, the chemical and protein 3D structures with hydrogen atoms were optimized by energy minimization and stored in MDL MOL and PDB format, respectively. KiBank is designed to support structure-based drug design. It provides structure files of proteins and chemicals ready for use in virtual screening through automated docking methods, while the K sub(i) values can be applied for tests of docking/scoring combinations, program parameter settings, and calibration of empirical scoring functions. Additionally, the chemical structures and corresponding K sub(i) values in KiBank are useful for lead optimization based on quantitative structure-activity relationship (QSAR) techniques. KiBank is updated on a daily basis and is freely available at http://kibank.iis.u-tokyo.ac.jp/, . As of August 2004, KiBank contains 8000 K sub(i) values, over 6000 chemicals and 166 proteins covering the subtypes of receptors and enzymes.

This has been prompted by an increase in human disease agents detectable in environmental samples, the potential for bioterrorism, and the lowering of international trade barriers and expansion of personal travel, which are bringing previously considered exotic diseases to new geographical localities. To appreciate the complexities of developing detection methods and working with environmental samples, it is appropriate to review technologies currently in use, as well as those in development and presently limited to research laboratories. Discussion of parasite detection would not be possible without including methods for parasite sampling, concentration, and purification because it is often necessary to process large sample volumes prior to analysis, and no reliable methods are available for significantly amplifying parasites in vitro. Reviewing proven methods currently in use will provide a baseline for generating, accepting and implementing the more sensitive and specific methods under development today.

Fire suppression in the Florida sandhills has the potential to alter upland and pond suitability through increased hardwood densities and resultant higher transpiration. In this paper, we explore breeding and metamorphic emigration movements in relation to weather, hydrological conditions of ponds, and surrounding upland matrices. We use nine years of data from continuous monitoring with drift fences and pitfall traps at eight ephemeral ponds in two upland matrices: regularly burned, savanna-like sandhills (N = 4), and hardwood-invaded sandhills (N = 4). Neither adult nor metamorph captures differed between ponds within the two upland matrices, suggesting that they are tolerant of upland heterogeneity created by fire frequency. Explosive breeding occurred during nine periods and in all seasons; adults were captured rarely otherwise. At the landscape-level, an interaction between rainfall and maximum change in barometric pressure were the top significant predictors of explosive breeding. At the pond-level, rainfall and the change in pond depth during the month prior to breeding were the top significant predictors of adult captures. Metamorphic emigrations occurred following transformation and usually were complete within a week regardless of rainfall levels. Movement by adults and metamorphs was directional, but mean directions of adult emigrations and immigrations did not always correspond. Our results suggest that spadefoot toads are highly adapted to breeding conditions and upland habitat heterogeneity created by weather patterns and fire frequency in Florida sandhills.

Considerable resources have been committed to detecting and controlling S. enteritidis infections in commercial laying flocks. Recently, the Centers for Disease Control and Prevention also reported a significant association between eggs or egg-containing foods and S. heidelberg infections in humans. The present study sought to determine whether several S. heidelberg isolates obtained from egg-associated human disease outbreaks were able to colonize reproductive tissues and be deposited inside eggs laid by experimentally infected hens in a manner similar to the previously documented behavior of S. enteritidis. In two trials, groups of laying hens were orally inoculated with large doses of four S. heidelberg strains and an S. enteritidis strain that consistently caused egg contamination in previous studies. All five Salmonella strains (of both serotypes) colonized the intestinal tracts and invaded the livers, spleens, ovaries, and oviducts of inoculated hens, with no significant differences observed between the strains for any of these parameters. All four S. heidelberg strains were recovered from the interior liquid contents of eggs laid by infected hens, although at lower frequencies (between 1.1% and 4.5%) than the S. enteritidis strain (7.0%).

Potential exists for nutrient removal directly from lagoons if vegetation can be grown on floating mats in the lagoon and periodically harvested and removed. Vegetative cover of lagoons may also help reduce odor problems. A study was conducted to determine the feasibility of using floating mats of vegetation on swine lagoon wastewater. Wastewater from the University of Georgia swine wastewater lagoons was pumped to replicated tanks (1285 L) in which floating mats of vegetation were grown. The floating platforms were made of PVC pipe with attached wire screen and fibrous material into which the vegetation was sprigged. Three different wetland species were tested: cattail (Typha latifolia L.), soft rush (Juncus effuses), and maidencane (Panicum hematomon Schult 'Halifax'). Full-strength wastewater, 1/2-strength wastewater, and an inorganic nutrient solution (1/4-strength Hoaglund solution) as a control were tested. The test was conducted as a modified batch process as opposed to a continuous flow through process. The modification was that every two weeks half of the volume of each tank was replaced with the appropriate solution of full-strength wastewater, 1/2-strength wastewater, or 1/4-strength Hoaglund solution so that nutrient concentrations would not be depleted. There were four replicate tanks of each nutrient solution for each wetland species, for a total of 36 tanks. Vegetation from the floating mats was harvested periodically by removing all vegetation above 5 cm of the base of the floating mat. Measurements were made at each cutting of the total biomass per tank, leaf area, and nutrient content (N, P, K) of the vegetative tissue. Growth responses were quite different among the three species. The cattail had tremendous growth during the spring and summer months. The growth rate of the rush was slow for the first year. It then died during summer of 2002 at both the 1/2-strength and full-strength wastewater, indicating that this species is not suitable for growth on floating mats in swine lagoon wastewater. Total nutrient removal by both the cattail and maidencane was primarily a function of total biomass produced. Over the length of the study, on full-strength wastewater, the cattail produced 16,511 g m super(-2) biomass and removed 534, 79, and 563 g m super(-2) of N, P, and K, respectively, while the maidencane produced 9751 g m super(-2) of biomass and removed 323, 48, and 223 g m super(-2) of N, P, and K, respectively. Results from this study indicate that potential exists for using floating platforms to grow cattail, maidencane, or possibly other yet to be identified plant species in wastewater lagoons for nutrient removal.

To assess the utility of near-infrared reflectance spectroscopy (NIRS) and diffuse mid-infrared reflectance spectroscopy (DRIFTS) for soil metal determination, 70 soil samples from the metal mining region of Tarnowskie Gory (Upper Silesia, Poland) were analyzed by both chemical and spectroscopic methods. Soils represented a wide range of pH (4.0-8.0), total carbon (5.1-73.2 g kg super(-1)), and textural classes (from sand to silty clay loam). Soils had various contents of metals (14-4500 mg kg super(-1) for Zn, 18-6530 mg kg super(-1) for Pb, and 0.17-34 mg kg super(-1) for Cd), ranging from natural background levels to high contents indicative of industrial contamination in the region. Soil samples were scanned at the wavelengths from 400 to 2498 nm (near-infrared region) and from 2500 to 25000 nm (mid-infrared region). Calibrations were developed using the one-out validation procedure under partial least squares (PLS) regression. Mid-infrared spectroscopy markedly outperformed NIRS. Iron, Cd, Cu, Ni, and Zn were successfully predicted using DRIFTS. The coefficients of determination (R super(2)) between actual and predicted contents were 0.97, 0.94, 0.80, 0.99, and 0.96 for those metals, respectively. Only Pb content was predicted poorly. Calibrations using NIRS were less accurate. Root mean squared deviation (RMSD) values were from 1.27 (Pb) to 3.3 (Ni) times higher for NIRS than for DRIFTS. Results indicate that DRIFTS may be useful for accurate predictions of metals if samples originate from one region.

To address this we analyzed manure from swine fed one of four barley (Hordeum vulgare L.) varieties. The barley types consisted of wild-type barley (CDC bold, normal barley diet) and three low-phytic-acid mutant barleys that contained similar amounts of total P but less phytic acid. The phytic acid concentrations in the mutant barleys were reduced by 32% (M422), 59% (M635), and 97% (M955) compared with that in the wild-type barley, respectively. Phosphorus concentrations were approximately one-third less in manures from animals fed low-phytic-acid barleys compared with those fed the wild-type variety. Phytic acid constituted up to 55% of the P in feed, but only trace concentrations were detected in NaOH-EDTA extracts of all manures by solution super(31)P nuclear magnetic resonance (NMR) spectroscopy. Phosphate was the major P fraction in the manures (86-94% extracted P), with small concentrations of pyrophosphate and simple phosphate monoesters also present. The latter originated mainly from the hydrolysis of phospholipids during extraction and analysis. These results suggest that phytic acid is hydrolyzed in swine, possibly in the hind gut by intestinal microflora before being excreted in feces, even though the animals have little phytase activity in the gut and derive little nutritional benefit from phytate P. We conclude that feeding low-phytic-acid grains reduces total manure P concentrations and the manure P is no more soluble than P generated from normal barley diets.

Much time is required to wash plant roots from soil and separate the living plant roots from organic debris and previous years' roots. We developed a root washer that can accommodate relatively large soil samples for washing. The root washer has a rotary design and will accommodate up to 24 samples (100 mm diam. by 240 mm long) at one time. We used a flat-bed scanner to digitize an image of the roots from each sample and used a grid system with commercially-available image analysis software to analyze each sample for root surface area. Sensitivity analysis and subsequent comparisons of 'dirty' samples containing the roots and all the organic debris contained in the sample and 'clean' samples where the organic debris was manually removed from each sample showed that up to 15% of the projected image could be coveredwith debris without affecting accuracy and precision of root surface area measurements. Samples containing a large amount of debris may need to be partitioned into more than one scanning tray to allow accurate measurements of the root surface area. Sample processing time was reduced from 20 h, when hand separation of roots from debris was used, to about 0.5 h, when analyzing the image from an uncleaned sample. The method minimizes the need for preprocessing steps such as dying the roots to get better image contrast for image analysis. Some information, such as root length, root diameter classes and root weights, is not obtained when using this technique. Root length measurements, if needed, could be made by hand on the digital images. Root weight measurement would require sample cleaning and the advantage of less processing time per sample with this method would be lost. The significance of the tradeoff between information not obtained using this technique and the ability to process a greater number of samples with the time and personnel resources available must be determined by the individual researcher and research objectives.

AN - 67042536; 15522729 AB - A high performance liquid chromatography/mass spectrometry (HPLC/MS) method was developed in support of a study to assess potential tertiary risks posed to insectivores by strychnine baited pocket gophers (Thomomys sp.). Necropholous insects are primary consumers of pocket gopher carcasses. A field study was conducted to collect insects from strychnine-baited and control pocket gopher carcasses. The majority of the insects collected were from the orders Diptera (flies, assayed separately as adults and larvae), Coleoptera (beetles), and Hymenoptera (ants and wasps, assayed separately). Samples (0.5 g) were extracted in acetic acid (2%) and analyzed with the mass spectrometer configured for tandem mass spectrometry. For most of the samples the strychnine concentrations were less than the method limit of detection. However, strychnine concentrations as high as 0.338, 0.341, 0.698, and 0.034 microg/g were detected in ants, fly adults, fly larvae, and beetles, respectively. This information collected with the HPLC/MS method is critical for assessing potential non-target hazards for insectivores. JF - Journal of chromatography.

Biomass production AN - 16185322; 6157838 AB - Reuse of saline drainage waters is a management option that has been suggested for the San Joaquin Valley (SJV) of California in order to reduce both the area affected by shallow water tables and the volume of drainage effluent requiring disposal. Salt-tolerant forages may play an important role in this strategy, while at the same time producing a food source for sheep and cattle. Crop selection for reuse systems, however, will depend upon production potential under saline-sodic conditions. To identify potentially suitable crops, a controlled study using an elaborate sand-tank system was conducted at the US Salinity Laboratory to evaluate ten promising forage crops irrigated with synthetic drainage waters dominated by Na sub(2)SO sub(4) with an EC of either 15 or 25dS/m each containing 500 mu g/L Se and Mo as SeO sub(4) super(2) super(-) and MoO sub(4) super(2) super(-). Forages were cut several times over the year-long duration of the experiment. The forage species tested performed differently in terms of absolute biomass accumulation and biomass production relative to salinity level. Cumulative biomass production of alfalfa (Medicago sativa L.), a relatively salt sensitive crop, was higher than most other forages at moderate salinity. As salinity increased to 25dS/m, however, cumulative biomass of the alfalfa cultivars were reduced by nearly half whereas biomass of the most salt tolerant grasses was reduced between 0 and 20%.

AN - 67062939; 15537318 AB - There are few studies that relate the timing and amounts of pesticide washoff from plant foliage during rainfall to runoff losses at the edge of the field. We hypothesized that foliar deposits, if washed onto the soil slowly during rainfall, may then undergo less leaching during the period of infiltration that occurs prior to soil saturation and runoff, thus exhibiting larger runoff losses than pesticides on/in the soil at the beginning of rain. We measured the runoff of ethalfluralin, metolachlor, chlorothalonil, and rhodamine WT dye using simulated rainfall on 450 m2 mesoplots planted in peanut. Ethalfluralin was applied preplant incorporated, and metolachlor was applied preemergence on bare soil. Chlorothalonil and rhodamine WT were applied to the peanut canopy at maturity. Rainfall was simulated 24 h after each chemical application (in May and July, 1998, and May and August, 1999) using raindrop sprinklers, applying 5.5 +/- 0.5 cm over a 2 h period to create reasonable worst-case conditions; between 3 and 9 mm of runoff was generated. Volume-weighted average concentrations of chemicals in runoff were 7, 104, 163, and 179 ug L(-1) for ethalfluralin, metolachlor, chlorothalonil, and rhodamine WT, respectively. The total amounts of chemicals lost in the runoff events were 0.04 +/- 0.01, 0.2 +/- 0.1, 0.6 +/- 0.5, and 0.2 +/- 0.1, as percents of amounts applied, respectively. Rhodamine WT formed a vivid red solution on wetting and provided visual clues to the dynamics of chemical washoff/runoff. The washoff from rain-exposed peanut foliage appeared to be complete within a few minutes of the beginning of rainfall, and disappearance of dye from rain-exposed soil surface occurred within the first 10 min of rainfall. However, dye was present in runoff water at near-constant concentrations throughout the 2 h runoff event, indicating that near-constant amounts of chemical remained in the soil extraction zone. These results confirm earlier studies showing that soil incorporation at application significantly reduces runoff losses and that a majority of foliar residues can be washable if rainfall occurs within a few days after application. Runoff losses of foliar-applied pesticides were small relative to washoff amounts but were sensitive to runoff timing relative to washoff.

Redox conditions were characterized by E sub(h), oxidative capacity (OXC), and terminal electron accepting processes (TEAPs) as well as examining the energetics of TEAPs. Groundwater chemistry related to redox status was determined by major solute concentrations, dissolved gases (O sub(2), H sub(2), CH sub(4)), aqueous redox species (NO super(-) sub(3), Mn super(2+), Fe super(2+)/Fe super(3+), SO super(2) sub(4) super(-)/HS super(-), DOC), and major redox sensitive components in the solid phase (extractable Fe/Mn). All of these measures of redox status indicate that sulfate reduction is the major process regulating redox conditions in most shallow groundwaters of Owens Dry Lake. Dissolved sulfate concentrations were regulated primarily by evaporation resulting in increasing concentrations as water migrates from the shoreline (<1 mM) to the center (up to 417 mM) of the dry lakebed. E sub(h) values were generally in the range of -240 to -170 mV. The oxidative capacity demonstrates the dominant contribution of sulfate to OXC. The dominance of sulfate restricts further redox development, such as methanogenesis. Dissolved H sub(2) concentrations ranged from 0.5 to 7.8 nM. According to the empirically defined H sub(2) ranges, sulfate reduction was the most predominant TEAP. Moreover, thermodynamic calculations of TEAPs for H sub(2) utilization support favorable energetics for both sulfate reduction and methanogenesis. The calculated available energy yield for sulfate reduction in the shallow groundwater of Owens Dry Lake was higher than other systems due to the high sulfate concentration.

The product of the agrA gene has been shown by amino acid sequence similarity to be the putative response regulator; however, binding of AgrA to promoters under its control has not yet been demonstrated. In this study, we isolated and purified soluble AgrA by expression under osmotic shock conditions and ion-exchange chromatography. Purified AgrA showed high-affinity binding to the RNAIII-agr intergenic region by electrophoretic mobility shift assays. Binding was localized by DNase I protection assays to a pair of direct repeats in the P2 and P3 promoter regions of the agr locus. We found that this binding was enhanced by the addition of the small phosphoryl donor, acetyl phosphate. The difference in binding affinity between these two promoters was found to result from a 2-bp difference between the downstream direct repeats of the P2 and P3 sites. Mutation of these base pairs in the P3 site to match those found in the P2 site increased the affinity of AgrA for the P3 site relative to that for the P2 site. These results are consistent with the function of AgrA as a response regulator with recognition sites in the promoter regions of RNAIII and the agr locus.

AN - 67019605; 15506811 AB - Pesticides may be dispersed throughout the environment by several means, including groundwater contamination, surface water contamination, and volatilization with subsequent atmospheric transport and deposition. In earlier research primarily directed at reducing the potential for groundwater contamination, a number of herbicides were microencapsulated within several different polymers. These polymeric formulations were evaluated for efficacy in the greenhouse. In the studies described in this paper, three polymeric alachlor formulations that were the most effective in the greenhouse were evaluated in laboratory volatility studies using pure alachlor and a commercial formulation (Lasso 4EC) for comparison purposes. In a given experiment, technical alachlor, Lasso 4EC, and two polymeric formulations were applied to soil and evaluated in a contained system under 53% humidity with a fixed flow rate. Evolved alachlor was collected in ethylene glycol, recovered with C18 solid phase extraction cartridges, and analyzed by reverse-phase high-performance thin-layer chromatography with densitometry. Duration of the studies ranged from 32 to 39 days. In studies in which all formulations were uniformly incorporated in the soil, total alachlor volatilization from the polymeric microcapsules was consistently lower than that from the alachlor and Lasso 4EC formulations. In studies in which the polymeric formulations were sprinkled on the surface of the soil, microcapsules prepared with the polymer cellulose acetate butyrate released the smallest quantity of volatilized alachlor.

AN - 759321673; 13771085 AB - The United States is making the transition from the 1979 1 hr maximum ozone standard to the newly adopted 8 hr ozone standard (3 yr average of the 4th highest maximum 8 hr ozone concentration). Consequently, we analyzed and compared ozone concentrations under both standards from a variety of monitoring sites throughout the central Appalachianregion of Kentucky (KY), West Virginia (WV), and Virginia (VA). Data from 1988-1999 were used to determine how ozone exposure between the two metrics compared for remote sites. Most sites exceeded the 1 hr standard in 1988-1990 due to the 3 yr averaging and multiple high ozone concentrations that occurred over the region in 1988. All sites were in compliance with the 1 hr standard every year after 1991. It was much more common for the ozone exposure to exceed the 8 hr standard, particularly from 1997-1999. Many sites showed exceedences beginning in 1995; Big Meadows (VA) exceeded the 8 hr standard all years except 1994 and 1996. Response of vegetation to ozone in these areas was determined using the combination of W126 values (sigmoidally weighted exposure index), the number of hours that average concentrations .0.10 ppm (N100), and the presence of moderate or more extreme droughts. In general, W126 and N100 values suggested that negative vegetation growth responses over most of the 12 yr would have been minimal for most sites, even for those exceeding ozone standards. Drought-induced stomatal closures would have overridden more extreme negative growth responses at all but the Big Meadows site in 1988.

AN - 67285159; 15868477 AB - Antimutagenic, anticlastogenic, and bioprotective effect of polysaccharide glucomannan (GM) isolated from Candida utilis was evaluated in four model test systems. The antimutagenic effect of GM against 9-aminoacridine (9-AA)- and sodium azide (NaN3)-induced mutagenicity was revealed in the Salmonella typhimurium strains TA97 and TA100, respectively. GM showed anticlastogenic effect against N-nitroso-N'-methylurea (NMU) induced chromosome aberrations in the Vicia sativa assay. The bioprotective effect of GM co-treated with methyl-methane-sulphonate (MMS) was also established in Chlamydomonas reinhardtii repair deficient strains uvs10 and uvs14. The statistically significant antimutagenic potential of GM was not proved against 4-nitro-quinoline-1-oxide (4-NQO)-induced mutagenicity in Saccharomyces cerevisiae D7 assay. It may be due to bioprotectivity of alpha-mannan and beta-glucan, which are integral part of S. cerevisiae cell walls. Due to the good water solubility, low molecular weight (30 kDa), antimutagenic/anticlastogenic, and bioprotective activity against chemical compounds differing in mode of action, GM appears to be a promising natural protective (antimutagenic) agent.

AN - 67084453; 15553650 AB - To evaluate the effect of processing on the safety and quality of retail shell eggs, a storage study was conducted with unwashed and commercially washed eggs. This work demonstrated that commercial processing decreased microbial contamination of eggshells. To know which species persisted during storage on washed or unwashed eggs, Enterobacteriaceae isolates were selected and identified biochemically. For each of three replications, shell eggs were purchased from a commercial processing plant, transported back to the laboratory, and stored at 4 degrees C. Once a week for 6 weeks, 12 eggs for each treatment (washed and unwashed control) were rinsed in sterile phosphate-buffered saline. A 1-ml aliquot of each sample was plated onto violet red bile glucose agar with overlay and incubated at 37 degrees C for 24 h. Following incubation, plates were observed for colonies characteristic of the family Enterobacteriaceae. A maximum of 10 isolates per positive sample were streaked for isolation before being identified to the genus or species level using commercially available biochemical strips. Although most of the isolates from the unwashed control eggs belonged to the genera Escherichia or Enterobacter, many other genera and species were identified. These included Citrobacter, Klebsiella, Kluyvera, Pantoea, Providencia, Rahnella, Salmonella, Serratia, and Yersinia. Non-Enterobacteriaceae also recovered from the unwashed egg samples included Xanthomonas and Flavimonas. Very few washed egg samples were contaminated with any of these bacteria. These data provide useful information on the effectiveness of processing in removing microorganisms from commercial shell eggs.

AN - 67084393; 15553632 AB - Contamination of fresh produce with Listeria monocytogenes has resulted in outbreaks of systemic listeriosis and febrile gastroenteritis. Recalls of alfalfa sprouts have occurred due to contamination with L. monocytogenes. Alfalfa sprouts were used as a preharvest model to study the interaction with this human pathogen. Seventeen strains were assessed for their capacity to colonize alfalfa sprouts, and strain-specific differences (not related to source, serotype, or lineage) were revealed when the sprout irrigation water was changed daily. Two of the strains colonized and attached to the sprouts very well, reaching levels of more than 5 log CFU per sprout. The remaining strains varied in their final levels on sprouts between less than 1 to 4.7 log CFU per sprout. All of the L. monocytogenes strains grew to equivalent levels on the sprouts when the irrigation water was not changed, suggesting the differences observed with regular changing of the water resulted from differences in attachment. Further analysis of the best colonizing strains indicated that only between 0.3 and 1 log CFU per sprout could be removed by additional washing of the sprout, and the presence of normal sprout bacteria did not compete with the L. monocytogenes strains on the sprouts. The poorest colonizing strain was able to grow in the irrigation water during the experiment but could not attach to the sprouts. Microscopic examination of the sprouts with L. monocytogenes expressing the green fluorescent protein indicated that L. monocytogenes was associated with the root hairs of the sprouting alfalfa, with few to no cells visible elsewhere on the sprout.

AN - 67071125; 15537938 AB - Combining several soil fumigants to increase the broad spectrum of pest control is a common fumigation practice in current production agriculture. In this study, we investigated the effect of combined application of chloropicrin and methyl isothiocyanate (MITC) on their transformations and persistence in the environment. In aqueous solution, no direct reaction between MITC and chloropicrin occurred and relatively slow rates of hydrolysis of these compounds were observed in aquatic environments free of suspended solids. The transformation of chloropicrin, however, was accelerated in aqueous solution with MITC because of a reduction reaction with bisulfide (HS(-)), which is a by-product of MITC hydrolysis. In soil, when fumigants were applied simultaneously, the degradation of MITC was suppressed under the bi-fumigant application due to the inhibition of soil microbial activity and a possible abiotic competition with chloropicrin for a limited number of reaction sites on the surface of soil particles. However, the degradation rate of chloropicrin was significantly enhanced in the bi-fumigant soil system, which was primarily attributed to the reaction of chloropicrin and HS(-). Two sequential application approaches were developed to investigate the feasibility of the combined application of metam sodium (parent compound of MITC) and chloropicrin in soil and assess their potential effects on environmental fate. For both application sequences, the degradation of chloropicrin was accelerated and that of MITC, as a major breakdown product of metam sodium, was inhibited in soil.

AN - 67069260; 15537936 AB - Usage of glyphosate [N-(phosphonomethyl)-glycine] and glufosinate [2-amino-4-(hydroxy-methylphosphinyl)butanoic acid] may reduce the environmental impact of agriculture because they are more strongly sorbed to soil and may be less toxic than many of the residual herbicides they replace. Preferential flow complicates the picture, because due to this process, even strongly sorbed chemicals can move quickly to ground water. Therefore, four monolith lysimeters (8.1 m(2) by 2.4 m deep) were used to investigate leaching of contact and residual herbicides under a worst-case scenario. Glufosinate, atrazine (6-chloro-N(2)-ethyl-N(4)-isopropyl-1,3,5-triazine-2,4-diamine), alachlor [2-chloro-N-(2,6-diethylphenyl)-N-(methoxymethyl) acetamide], and linuron (3-3,4-dichlorophenyl-1-methoxy-1-methylurea) were applied in 1999 before corn (Zea mays L.) planting and glyphosate, alachlor, and metribuzin [4-amino-6-(1,1-dimethylethyl)-3-(methylthio)-1,2,4-triazin-5(4H)-one] were applied in 2000 before soybean [Glycine max (L.) Merr.] planting. A high-intensity rainfall was applied shortly after herbicide application both years. Most alachlor, metribuzin, atrazine, and linuron losses occurred within 1.1 d of rainfall initiation and the peak concentration of the herbicides coincided (within 0.1 d of rainfall initiation in 2000). More of the applied metribuzin leached compared with alachlor during the first 1.1 d after rainfall initiation (2.2% vs. 0.035%, P < 0.05). In 1999, 10 of 24 discrete samples contained atrazine above the maximum contaminant level (atrazine maximum contaminant level [MCL] = 3 mug L(-1)) while only one discrete sample contained glufosinate (19 mug L(-1), estimated MCL = 150 mug L(-1)). The results indicate that because of preferential flow, the breakthrough time of herbicides was independent of their sorptive properties but the transport amount was dependent on the herbicide properties. Even with preferential flow, glyphosate and glufosinate were not transported to 2.4 m at concentrations approaching environmental concern.

AN - 67068145; 15537931 AB - Nickel phytoextraction using hyperaccumulator plants offers a potential for profit while decontaminating soils. Although soil pH is considered a key factor in metal uptake by crops, little is known about soil pH effects on metal uptake by hyperaccumulator plants. Two Ni and Co hyperaccumulators, Alyssum murale and A. corsicum, were grown in Quarry muck (Terric Haplohemist) and Welland (Typic Epiaquoll) soils contaminated by a Ni refinery in Port Colborne, Ontario, Canada, and in the serpentine Brockman soil (Typic Xerochrepts) from Oregon, USA. Soils were acidified and limed to cover pH from strongly acidic to mildly alkaline. Alyssum grown in both industrially contaminated soils exhibited increased Ni concentration in shoots as soil pH increased despite a decrease in water-soluble soil Ni, opposite to that seen with agricultural crop plants. A small decrease in Alyssum shoot Ni concentration as soil pH increased was observed in the serpentine soil. The highest fraction of total soil Ni was phytoextracted from Quarry muck (6.3%), followed by Welland (4.7%), and Brockman (0.84%). Maximum Ni phytoextraction was achieved at pH 7.3, 7.7, and 6.4 in the Quarry, Welland, and Brockman soils, respectively. Cobalt concentrations in shoots increased with soil pH increase in the Quarry muck, but decreased in the Welland soil. Plants extracted 1.71, 0.83, and 0.05% of the total soil Co from Welland, Quarry, and Brockman, respectively. The differences in uptake pattern of Ni and Co by Alyssum from different soils and pH were probably related to the differences in organic matter and iron contents of the soils.

AN - 67064441; 15537943 AB - Phosphorus (P) in runoff from pastures amended with poultry litter may be a significant contributor to eutrophication of lakes and streams in Georgia and other areas in the southeastern United States. The objectives of this research were to determine the effects of litter application rate and initial runoff timing on the long-term loss of P in runoff from surface-applied poultry litter and to develop equations that predict P loss in runoff under these conditions. Litter application rates of 2, 7, and 13 Mg ha(-1), and three rainfall scenarios applied to 1- x 2-m plots in a 3 x 3 randomized complete block design with three replications. The rainfall scenarios included (i) sufficient rainfall to produce runoff immediately after litter application; (ii) no rainfall for 30 d after litter application; and (iii) small rainfall events every 7 d (5 min at 75 mm h(-1)) for 30 d. Phosphorus loss was greatest from the high litter rate and immediate runoff treatments. Nonlinear regression equations based on the small plot study produced fairly accurate (r(2) = 0.52-0.62) prediction of P concentrations in runoff water from larger (0.75 ha) fields over a 2-yr period. Predicted P concentrations were closest to observed values for events that occurred shortly after litter application, and the relative error in predictions increased with time after litter application. In addition, previously developed equations relating soil test P levels to runoff P concentrations were ineffective in the presence of surface-applied litter.

AN - 67064416; 15537922 AB - Conventional throughfall collection methods are labor intensive and analytically expensive to implement at broad scales. This study was conducted to test an alternative approach requiring infrequent sample collection and a greatly reduced number of chemical analyses. The major objective of the study was to determine the feasibility of using ion exchange resin (IER) to measure N deposition in throughfall with field deployment periods of 3 to 12 mo. Nitrogen deposition measurements in bulk throughfall collected under pine (Pinus sp.) canopies and in forest clearings were compared between co-located conventional throughfall solution collectors and IER throughfall collectors using mixed bed IER columns. Deposition data were collected for 1 yr at a high deposition site (Camp Paivika, CP) and a relatively low one (Barton Flats, BF) in the San Bernardino Mountains in southern California: Annual throughfall deposition values (kg ha(-1) of NH(4)-N + NO(3)-N) under large ponderosa pine trees (Pinus ponderosa Laws.) were 145.8 and 143.9 at CP and 17.0 and 15.0 at BF according to the IER and conventional methods, respectively. Analogous values for bulk deposition in forest clearings were 15.6 and 12.3 at CP and 4.0 and 3.3 at BF. It was concluded that the IER collectors can be used for routine monitoring of deposition in throughfall and bulk deposition, provided that field blanks are used to account for background levels of N in the IER columns, which at times are slightly elevated, possibly from slow release of amine groups from the anion exchange resin during field exposures.

AN - 67062829; 15532691 AB - Brown rice is used as a bait-carrier for the avicide DRC-1339 (3-chloro-4-methylaniline) when baiting blackbirds (Icteridae). In March and April 1996 and 1997, we assessed non-target granivorous bird use of rice-baited plots placed in harvested corn and soybean fields in eastern South Dakota for 168 observation hours. In both years combined, we identified 10 and 14 granivorous species in corn and soybean fields, respectively. In 1996 (X = 0.2, SE = 0.04) and 1997 (X = 1.2, SE = 0.38), total numbers of granivores min(-1) were similar between crops (P > or = 0.322). In 1996, bird numbers were higher (P = 0.069) in rice-baited fields (X = 0.3, SE = 0.07) than in unbaited reference fields (X = 0.1, SE = 0.04). In 1997, bird numbers (X = 1.2, SE = 0.38) did not differ between treatments (P = 0.456). Our data show that small numbers of non-target birds visited the rice-baited plots. However, total number of different individual birds using the plots was unknown.

AN - 67062218; 15537946 AB - When improperly managed, land application of animal manures can harm the environment; however, limited watershed-scale runoff water quality data are available to research and address this issue. The water quality impacts of conversion to poultry litter fertilization on cultivated and pasture watersheds in the Texas Blackland Prairie were evaluated in this three-year study. Edge-of-field N and P concentrations and loads in surface runoff from new litter application sites were compared with losses under inorganic fertilization. The impact on downstream nutrient loss was also examined. In the fallow year with no fertilizer application, nutrient losses averaged 3 kg N ha(-1) and 0.9 kg P ha(-1) for the cultivated watersheds and were below 0.1 kg ha(-1) for the pasture watersheds. Following litter application, PO(4)-P concentrations in runoff were positively correlated to litter application rate and Mehlich-3 soil P levels. Following litter application, NO(3)-N and NH(4)-N concentrations in runoff were typically greater from cultivated watersheds, but PO(4)-P concentrations were greater for the pasture watersheds. Total N and P loads from the pasture watersheds (0.2 kg N ha(-1) and 0.7 kg P ha(-1)) were significantly lower than from the cultivated watersheds (32 kg N ha(-1) and 5 kg P ha(-1)) partly due to lower runoff volumes from the pasture watersheds. Downstream N and P concentrations and per-area loads were much lower than from edge-of-field watersheds. Results demonstrate that a properly managed annual litter application (4.5 Mg ha(-1) or less depending on litter N and P content) with supplemental N should supply necessary nutrients without detrimental water quality impacts.

AN - 67061947; 15537960 AB - Riparian zones are recognized as landscape features that buffer streams from pollutants, particularly nitrogen. The objectives of this experiment were to (i) assess denitrification activity within a riparian zone and (ii) determine the influence of physical, chemical, and landscape features on denitrification. This experiment was conducted from 1994 to 1997 in North Carolina on a riparian zone contiguous to a spray field that was heavily loaded with swine lagoon wastewater. Denitrification enzyme activity (DEA) was measured on soils collected from (i) the soil surface, (ii) midway between the soil surface and water table, and (iii) above the water table. The DEA ranged from 3 to 1660 microg N(2)O-N kg(-1) soil h(-1). The DEA was highest next to the stream and lowest next to the spray field. Nitrate was found to be the limiting factor for denitrification. The DEA generally decreased with soil depth; means for the surface, middle, and bottom depths were 147, 83, and 67 microg N(2)O-N kg(-1) soil h(-1), respectively. These DEA values are higher than those reported for riparian zones adjoining cropland of the southeastern United States, but are lower than those reported for a constructed wetland used for treatment of swine wastewater. Regression analysis indicated that soil total nitrogen was the highest single factor correlated to DEA (r(2) = 0.65). The inclusion of water table depth, soil depth, and distance from the spray field improved the R(2) to 0.86. This riparian zone possessed sufficient soil area with high denitrifying conditions to be a significant factor in the removal of excess nitrogen in the ground water.

AN - 67061680; 15537934 AB - In the Atlantic Coastal Plain region of southern Georgia (USA), cotton (Gossypium hirsutum L.) acreage increased threefold in the past decade. To more effectively protect water quality in the region, best management practices are needed that reduce pesticide runoff from fields in cotton production. This study compared runoff of two herbicides, fluometuron [N,N-dimethyl-N'-[3-(trifluoromethyl)-phenyl]-urea] and pendimethalin [N-(1-ethylpropyl)-3,4-dimethyl-2,6-dinitro-benzenamine], from plots in strip-tillage (ST) and conventional-tillage (CT) management near Tifton, GA. Rainfall simulations were conducted one day after preemergence herbicide applications to 0.0006-ha plots and runoff from 0.15-ha plots due to natural rainfall following preemergence pendimethalin and fluometuron and postemergence fluometuron use was monitored. Pendimethalin runoff was greater under CT than ST due to strong pendimethalin soil sorption and higher erosion and runoff under CT. The highest losses, 1.3% of applied in CT and 0.22% of applied in ST, were observed during rainfall simulations conducted 1 DAT. Fluometuron runoff from natural rainfall was substantially lower from ST than from CT plots but the trend was reversed in rainfall simulations. In all studies, fluometuron runoff was also relatively low (<1% of applied), and on plots under natural rainfall, desmethylfluometuron (DMF) represented about 50% of total fluometuron runoff. Fluometuron's relatively low runoff rate appeared linked to its rapid leaching, and high DMF detection rates in runoff support DMF inclusion in fluometuron risk assessments. Results showed that ST has the potential to reduce runoff of both herbicides, but fluometuron leaching may be a ground water quality concern.

AN - 67041810; 15528514 AB - Aspergillus flavus isolates produce only aflatoxins B1 and B2, while Aspergillus parasiticus and Aspergillus nomius produce aflatoxins B1, B2, G1, and G2. Sequence comparison of the aflatoxin biosynthesis pathway gene cluster upstream from the polyketide synthase gene, pksA, revealed that A. flavus isolates are missing portions of genes (cypA and norB) predicted to encode, respectively, a cytochrome P450 monooxygenase and an aryl alcohol dehydrogenase. Insertional disruption of cypA in A. parasiticus yielded transformants that lack the ability to produce G aflatoxins but not B aflatoxins. The enzyme encoded by cypA has highest amino acid identity to Gibberella zeae Tri4 (38%), a P450 monooxygenase previously shown to be involved in trichodiene epoxidation. The substrate for CypA may be an intermediate formed by oxidative cleavage of the A ring of O-methylsterigmatocystin by OrdA, the P450 monooxygenase required for formation of aflatoxins B1 and B2.

AN - 67038129; 15522090 AB - The Ca(2+)-dependent protein phosphatase calcineurin is an important regulator of ion transporters from many organisms, including the Saccharomyces cerevisiae vacuolar Ca(2+)/H(+) exchanger Vcx1p. In yeast and plants, cation/H(+) exchangers are important in shaping cytosolic Ca(2+) levels involved in signal transduction and providing tolerance to potentially toxic concentrations of cations such as Ca(2+), Mn(2+) and Cd(2+). Previous genetic evidence suggested Vcx1p is negatively regulated by calcineurin. By utilizing direct transport measurements into vacuolar membrane vesicles, we demonstrate that Vcx1p is a low-affinity Ca(2+) transporter and may also function in Cd(2+) transport, but cannot transport Mn(2+). Furthermore, direct Ca(2+) transport by Vcx1p is calcineurin sensitive. Using a yeast growth assay, a mutant allele of VCX1 (VCX1-S204A/L208P), termed VCX1-M1, was previously found to confer strong Mn(2+) tolerance. Here we demonstrate that this Mn(2+) tolerance is independent of the Ca(2+)/Mn(2+)-ATPase Pmr1p and results from Mn(2+)-specific vacuolar transport activity of Vcx1-M1p. This Mn(2+) transport by Vcx1-M1p is calcineurin dependent, although the localization of Vcx1-M1p to the vacuole appears to be calcineurin independent. Additionally, we demonstrate that mutation of L208P alone is enough to confer calcineurin-dependent Mn(2+) tolerance. This study demonstrates that calcineurin can positively regulate the transport of cations by VCX1-M1p.

AN - 67037894; 15522613 AB - Extensive use of insecticides on cotton in the mid-South has prompted resistance development in the tarnished plant bug, Lygus lineolaris (Palisot de Beauvois). A field population of tarnished plant bugs in Mississippi with 11-fold higher resistance to malathion was used to examine how gene regulation conferred resistance to this organophosphate insecticide. In laboratory bioassays, synergism by the esterase inhibitors S,S,S,-tributylphosphorotrithioate (DEF) and triphenylphosphate (TPP) effectively abolished resistance and increased malathion toxicity by more than 80%. Esterase activities were compared in vitro between malathion susceptible and resistant (selected) strains. More than 6-, 3- and 10-fold higher activities were obtained with the resistant strain using alpha-naphthyl acetate, beta-naphthyl acetate, and p-nitrophenyl acetate, respectively. Up to 95% and 89% of the esterase activity in the susceptible and resistant strains, respectively, was inhibited by 1 mM DEF. Inhibition of esterase activity up to 75% and 85% in the susceptible and resistant strains, respectively, was obtained with 0.03 mM TPP. Esterase activities in field populations increased by up to 5.4-fold during the fall season. The increase was synchronized with movement of the insect into cotton where exposure to pesticides occurred. Esterase cDNA was cloned and sequenced from both malathion susceptible and resistant strains. The 1818-nucleotide cDNA contained a 1710-bp open reading frame coding a 570 amino acid protein which was similar to many insect esterases conferring organophosphate resistance. No amino acid substitution was observed between susceptible and resistant strains, indicating that esterase gene mutation was not involved in resistance development in the resistant strain in Mississippi. Further examination of esterase gene expression levels using quantitative RT-PCR revealed that the resistant strain had a 5.1-fold higher level of esterase mRNA than the susceptible strain. The results of this study indicated that up-regulation of the esterase gene appeared to be related to the development of resistance in the tarnished plant bug.

Cellular fitness, measured as growth rate in a minimal medium, of UVR-exposed lineages of both B86-17 and GWS242 after 60 cycles was not significantly different from that of the ancestral strains.

AN - 67023986; 15514258 AB - Chronic and excessive ethanol intake in rats results in low levels of hepatic retinoic acid (RA) either by inhibiting the biosynthesis of RA or by enhancing its catabolism of RA. Chronic ethanol intake also decreases both hepatic expression of insulin-like growth factor-I (IGF-I) and plasma IGF-I concentration in rats. It is not known whether RA supplementation in alcohol-fed rats can restore plasma IGF-I concentrations and hepatic IGF-I expression. In the present study, we examined both plasma IGF-I level and hepatic IGF-I mRNA expression in alcohol-fed rats with or without RA (100 microg/kg body weight) supplementation for 6 mo. Hepatic IGF-I mRNA levels and plasma IGF-I concentration were decreased (84 and 29%, respectively) significantly in alcohol-fed rats compared with the control. In contrast, RA supplementation in ethanol-fed rats partially restored both hepatic IGF-I mRNA levels and plasma IGF-I concentration compared with rats fed ethanol alone. These data suggest that alcohol-impaired hepatic RA status contributes to the decreased plasma IGF-I level and hepatic IGF-I expression in alcoholics.

AN - 66999408; 15499359 AB - Between 250 and 350 million Americans are estimated to suffer acute gastroenteritis annually, with 25% to 30% thought to be caused by foodborne illnesses. Most vulnerable to foodborne diseases are elderly people, pregnant women, immune-compromised people, and children. While bacterial causes such as Salmonella are widely recognized and monitored as foodborne infections, other important bacterial causes such as Clostridium perfringens , Bacillus cereus , and Staphylococcus aureus are less well known. While the majority of cases of foodborne diseases are of unknown cause, bacteria and viruses are the most likely causative agents. Caliciviridae (Norwalk-like) virus cases are more difficult to identify, but represent the most common cause of known and probably unknown cases. Fresh produce has to be added to the traditional list of foods requiring careful selection and handling to prevent foodborne disease. To assess the disease burden in the United States, morbidity and mortality surveillance activities are done by several networks and systems with collaboration among federal agencies and health departments. Not all important causes are being equally monitored. Critical behaviors by food processors, food retailers, foodservice personnel, and consumers can reduce the risk of foodborne illness episodes. Dietetics professionals can more readily monitor new developments and update knowledge and practice through online resources.

AN - 66975004; 15488576 AB - Constructed wetlands offer promise for removal of nonpoint source contaminants such as herbicides from agricultural runoff. Laboratory studies assessed the potential of soils to degrade and sorb atrazine and fluometuron within a recently constructed wetland. The surface 3 cm of soil was sampled from two cells of a Mississippi Delta constructed wetland; one shallow area disturbed only hydrologically, and the second excavated to provide greater water-holding capacity. The excavated area was more acidic on average (pH 4.85 versus 5.21), but otherwise the physical properties and general microbial enzyme activities in the two areas were similar. Soils were treated with 84 and 68 microg kg(-1) soil (14)C-ring labeled atrazine and fluometuron, respectively, and incubated under either saturated (88% moisture, w:w) or flooded (1cm standing water) conditions. Soils were sampled over 32 days and extracted for herbicide and metabolite analysis. Under saturated conditions, fluometuron metabolized to desmethylfluometuron (DMF) with a half-life equal 25-27 days. However, under flooded conditions, the half-life of fluometuron was more than 175 days. Atrazine dissipated rapidly in saturated and flooded soil with a half-life of approximately 23 days, but only 10% of atrazine was mineralized to CO(2). The overall atrazine and fluometuron dissipation rates were similar between the two cells, but each area had a different pattern of metabolite accumulation. The major route of atrazine dissipation was incorporation of atrazine residues into methanol-nonextractable (soil-bound) components, with minimal extractable metabolite accumulation. A mixed-mode extractant (potassium phosphate:acetonitrile) recovered greater amounts of (14)C-residues from atrazine-treated soils, suggesting that hydrolysis of atrazine to hydroxylated metabolites was a major component of the bound residues. These studies indicate the potential for herbicide dissipation in wetland soils and a differential effect of flooding on the fate of these herbicides.

AN - 66939516; 15471705 AB - Attention to worldwide pollution of the coastal marine environment has focused primarily on toxic algal blooms and pathogenic bacteria that multiply in nutrient-rich waters. However, massive but unseen amounts of feces from humans, their pets, and their domesticated animals are discharged, dumped, or carried in runoff, bringing encysted zoonotic protozoan parasites to estuaries and coastal waters. Here, they contaminate bathing beaches, are filtered and concentrated by shellfish eaten by humans and marine mammals, and infect a wide range of marine animal hosts, resulting in morbidity and mortality to some populations. This review addresses the extent of contamination and the animals affected by three genera of important zoonotic protozoa: Giardia, Cryptosporidium and Toxoplasma.

AN - 66869095; 15364599 AB - Dietary minerals Zn, Fe, and Ca are antagonistic to Cd absorption. We showed earlier that rats fed a rice-based diet with a marginal content of these nutrients absorbed more Cd than rats fed adequate Zn-Fe-Ca (Environ. Sci. Technol., 36 (2002) 2684-2692). The present experiment was designed to determine the effects of marginal dietary Zn, Fe, and Ca on the uptake and turnover of Cd in the gastrointestinal tract. Two groups of weanling female rats (six per treatment) were fed a diet containing 40% cooked, dried rice containing 0.6 mg Cd/kg. The diet of one group contained adequate Zn (35 mg/kg), Fe (30 mg/kg), and Ca (5000 mg/kg), while that of the other group contained marginal Zn (6 mg/kg), Fe (9 mg/kg), and Ca (2500 mg/kg). Rats were fed for 5 weeks and then orally dosed with 1g of diet containing rice extrinsically labeled with 109Cd. From 0.25 to 64 days after dosing, 109Cd and total Cd concentrations were determined in intestinal segments. Shortly after dosing, 109Cd, as a percentage of the dose, was about 4 times higher in the duodenum of marginally fed rats than in that of control rats (10% vs 40%, respectively). Sixty-four days after dosing, 109Cd was 10 times higher in marginally fed rats than in controls; however, of the amount at day 1, <0.1% remained at day 64. After 5 weeks, the concentration of elemental Cd in the duodenum of the marginally fed rats was 8 times higher than that of control rats (24 microg/g dry wt. vs 2.9 microg/g dry wt., respectively). Cd concentrations in liver and kidney were 5 times higher in the marginally fed rats than those in controls (liver, 0.81 microg/g dry wt. vs 0.14 microg/g dry wt.; kidney, 4.7 microg/g dry wt. vs 0.92 microg/g dry wt., respectively). These data suggest that marginal intakes of Zn, Fe, and Ca cause the accumulation of Cd in the duodenum, which results in a greater rate of Cd absorption and a greater accumulation in the internal organs. Results are discussed in relation to mineral nutrient status and risk assessment of Cd in natural food sources.

Swine wastewater was applied to six, m-p-m wetlands in Greensboro, NC, USA, during two experimental periods, summer and winter. The efficiency of each system to remove the following wastewater constituents was determined: total suspended solids (TSS); chemical oxygen demand (COD); nitrogen (N); phosphorus (P). During the study, the wetlands removed an average 35-51% of TSS, 30-50% of COD, 37-51% of total N, and 13-26% of total P from swine wastewater. For wastewater COD and N, treatment efficiency was significantly lower during the winter experimental period compared to the summer. Treatment efficiency for all constituents tended to decrease with decreasing air temperatures and increasing rainfall amounts.

Fifty-three flies reared from nine species of Melaleuca L. were sequenced. Species boundaries delimited by mitochondrial data confirm recent morphological investigation with one exception. Fergusonina turneri Taylor, believed to feed on both Melaleuca quinquenervia (Cav.) S. T. Blake and Melaleuca fluviatilis Barlow, seems to be comprised of two cryptic species, each specialized on one of the two hosts. Because F. turneri is under consideration as a potential biological control agent for invasive M. quinquenervia in the Florida Everglades, understanding cryptic variation and the degree of dietary specialization of this species is critical.

Standard errors for inequality indices are calculated using a bootstrap approach which replicates the sample design. Standard errors for poverty indices are corrected for the design effects resulting from sample stratification and clustering. The authors use data from the Egypt Integrated Household Survey and follow the cost-of-basic-needs methodology to construct region-specific poverty lines. It is found that 15.7 million people were poor in Egypt in 1997, or 26.5% of the population. The estimates indicate a sharp sectoral difference with rural areas being significantly poorer, but significant differences in poverty were not found between Upper and Lower Egypt. This finding differs substantially from the conventional wisdom that Upper Egypt is poorer than Lower Egypt and results from the correction for spatial-price variation.

Characterization of a Novel Heavy Metal Transporting ATPase AN - 19809611; 6079413 AB - Thlaspi caerulescens is a heavy metal hyperaccumulator plant species that is able to accumulate extremely high levels of zinc (Zn) and cadmium (Cd) in its shoots (30,000 mu g g super(-1) Zn and 10,000 mu g g super(-1) Cd), and has been the subject of intense research as a model plant to gain a better understanding of the mechanisms of heavy metal hyperaccumulation and tolerance and as a source of genes for developing plant species better suited for the phytoremediation of metal-contaminated soils. In this study, we report on the results of a yeast (Saccharomyces cerevisae) complementation screen aimed at identifying candidate heavy metal tolerance genes in T. caerulescens. A number of Thlaspi genes that conferred Cd tolerance to yeast were identified, including possible metal- binding ligands from the metallothionein gene family, and a P-type ATPase that is a member of the P sub(1B) subfamily of purported heavy metal-translocating ATPases. A detailed characterization of the Thlaspi heavy metal ATPase, TcHMA4, demonstrated that it mediates yeast metal tolerance via active efflux of a number of different heavy metals (Cd, Zn, lead [Pb], and copper [Cu]) out of the cell. However, in T. caerulescens, based on differences in tissue-specific and metal-responsive expression of this transporter compared with its homolog in Arabidopsis (Arabidopsis thaliana), we suggest that it may not be involved in metal tolerance. Instead, we hypothesize that it may play a role in xylem loading of metals and thus could be a key player in the hyperaccumulation phenotype expressed in T. caerulescens. Additionally, evidence is presented showing that the C terminus of the TcHMA4 protein, which contains numerous possible heavy metal-binding His and Cys repeats residues, participates in heavy metal binding. When partial peptides from this C-terminal domain were expressed in yeast, they conferred an extremely high level of Cd tolerance and Cd hyperaccumulation. The possibilities for enhancing the metal tolerance and phytoremediation potential of higher plants via expression of these metal- binding peptides are also discussed.

RESEARCH METHODS AND PROCEDURES: Two 24-hour dietary recalls from the Continuing Surveys of Food Intakes by Individuals 1994 to 1996 and 1998 (1005 boys, 990 girls) were averaged, and children were categorized into three age groups: 3 to 5 years (n = 1077), 6 to 11 years (n = 537), and 12 to 19 years (n = 381). Physiologically implausible reports due to reporting bias or abnormal intake (rEI outside +/-18% to 23% of predicted energy requirements; pER) were identified. RESULTS: rEI averaged 109 +/-34% and 100 +/-10% of pER in the total and plausible samples, respectively. EI was overreported more in younger children and underreported more in overweight older children. Children with plausible rEI (45.3% of sample) averaged 4.7 eating occasions/d, 589 kcal/meal, 223 kcal/snack, and 2038 kcal/d. rEI was not associated with BMI percentile in the total sample. In the plausible sample, rEI, meal portion size, and meal energy were positively associated with BMI percentile in boys 6 to 11 years and in children 12 to 19 years. No relationships were found in children 3 to 5 years and girls 6 to 11 years. Relationships were more consistent and stronger in the plausible compared with the total sample. DISCUSSION: Excluding implausible dietary reports may be necessary for discerning dietary associations with BMI percentile. EI and meal, but not snack, patterns may play a quantitatively greater role in weight regulation as children age.

Texasweed produced an average of 893 seed per plant, and 90% were viable. Seed exhibited dormancy, and prechilling did not release dormancy. Percent germination ranged from 56% for seed subjected to no prechilling to 1% for seed prechilled at 5 C for 140 d. Seed remained viable during extended prechilling conditions, with 80% of seed viable after 140 d of prechilling. Texasweed seed germinated over a range of 20 to 40 C, with optimum germination (54%) occurring with a fluctuating 40/30 C temperature regime. Seed germinated with fluctuating 12-h light/dark and constant dark conditions. Texasweed seed germinated over a broad range of pH, osmotic potential, and salt concentrations. Seed germination was 31 to 62% over a pH range from 4 to 10. Germination of texasweed ranged from 9 to 56% as osmotic potential decreased from -0.8 MPa to 0 (distilled water). Germination was greater than 52% at less than 40 mM NaCl concentrations and lowest (27%) at 160 mM NaCl. Texasweed seedlings emerged from soil depths as deep as 7.5 cm (7% emergence), but emergence was >67% for seed placed on the soil surface or at a 1-cm depth. Texasweed seed did not germinate under saturated or flooded conditions, but seed survived flooding and germinated (23 to 25%) after flood removal. Texasweed seedlings 2.5 to 15 cm tall were not affected by emersion in 10-cm-deep flood for up to 14 d. These results suggest that texasweed seed is capable of germinating and surviving in a variety of climatic and edaphic conditions, and that flooding is not a viable management option for emerged plants of texasweed.

The objective of this study is to determine the feasibility of estimating concentrations of nitrogen, neutral detergent fiber (NDF), and acid detergent fiber (ADF) of live, standing forages using a hand-held hyperspectral spectroradiometer (radiometer), and to compare these estimates to values determined via NIRS and laboratory chemical methods. Calibration equations were developed from canopy reflectance measurements from monocultures of Bermuda grass and then applied to a test data set to predict N, NDF, and ADF. Statistical analyses showed that forage composition estimates from the radiometer were equivalent to those from the NIRS. Such a remote-sensing approach would enable real-time assessment of forage quality, would allow mapping of the nutritional landscape, could be used as a tool to better manage pastures and supplements, and would assist in making harvesting decisions.

The classification was developed to provide a foundation for comparing models and to help identify the appropriate fire and vegetation processes and their simulation to include in coarse scale dynamic global vegetation models. Other uses include a decision tool for research and management applications and a vehicle to interpret differences between LFSMs. The classification is based on the four primary processes that influence fire and vegetation dynamics: fire ignition, fire spread, fire effects, and vegetation succession. Forty-four LFSMs that explicitly simulated the four processes were rated by the authors and the modelers on a scale from 0 to 10 for their inherent degree of stochasticity, complexity, and mechanism for each of the four processes. These ratings were then used to group LFSMs into similar classes using common ordination and clustering techniques. Another database was created to describe each LFSM using selected keywords for over 20 explanatory categories. This database and the ordination and clustering results were then used to create the final LFSM classification that contains 12 classes and a corresponding key. The database and analysis results were used to construct a second classification key so managers can pick the most appropriate model for their application based on computer resources, available modeling expertise, and management objective.

The frequency of Fusarium detected varied from site to site and year to year. Fusarium was generically detected more frequently in leaf axil material than in leaf/husk lesions. In two growing seasons, the leaf axil samples were also tested for the presence of the mycotoxin producing species F. proliferatum, F. subglutinans, and F. verticillioides. Overall, F. proliferatum and F. verticillioides were detected less often than F. subglutinans. Fusarium was generically and specifically detected most commonly where visible fungal growth was present in leaf axil material.

Methods and Results: Waste slurries (faeces : urine : water, 50 : 35 : 15) were blended with and without additives and aliquoted to triplicate 1-l flasks. Faecal coliforms were eliminated in cattle and swine waste slurries within 1 or 2 days with additions of eugenol at 10.05 mm (0.15%) and 16.75 mm (0.25%). At these concentrations volatile fatty acids (VFA) were reduced ca 70 and 50% in cattle and swine waste, respectively, over 6-8 weeks. Additionally, in cattle waste, eugenol stimulated the accumulation of lactate (>180 mm) when compared with thymol treatment (20 mm lactate). In swine waste, lactate accumulation did not occur without additives; eugenol and thymol stimulated lactate accumulation to concentrations of 22 and 32 mm, respectively. Conclusions: Eugenol added to cattle waste may be more beneficial than thymol because not only does it effectively control faecal coliforms and odour (VFA production), it also stimulates lactate accumulation. This in turn, causes the pH to drop more rapidly, further inhibiting microbial activity and nutrient emissions. Significance and Impact of the Study: Plant essential oils have the potential to solve some of the environmental problems associated with consolidated animal feeding operations. Thymol and eugenol reduce fermentative activity, thus, have the potential to reduce emissions of greenhouse gases and odour, and curtail transmission of pathogens in cattle and swine wastes.

Somatic embryos of red spruce (Picea rubens) at different developmental stages, grown in the embryo development and maturation media for various lengths of time, were separated from the associated subtending tissue (embryogenic and the suspensor cell masses) and analyzed for their polyamine content as well as for polyamine biosynthetic enzyme activities. Polyamine content was also analyzed in embryos representing different stages of development that were collected from the same culture plate at the same time and the subtending tissue surrounding them. Putrescine was the predominant polyamine in the pro-embryogenic tissue, while spermidine was predominant during embryo development. Significant changes in spermidine/putrescine and spermine /putrescine ratios were observed at all stages of embryo development as compared to the pro-embryogenic cell mass. Changes in the ratios of various polyamines were clearly correlated with the developmental stage of the embryo rather than the period of growth in the maturation medium. Whereas the activities of both ornithine decarboxylase and arginine decarboxylase increased by week 3 or 4 and stayed high during the subsequent 6 wk of growth, the activity of S-adenosylmethionine decarboxylase steadily declined during embryo development.

As a result, Fusarium graminearum quickly has become one of the most intensively studied fungal plant pathogens. This review briefly summarizes current knowledge on the pathogenicity, population genetics, evolution and genomics of Fusarium graminearum. Taxonomy:Based on the sexual state Gibberella zeae (Schwein.) Petch: Superkingdom Eukaryota; Kingdom Fungi; Phylum Ascomycota; Subphylum Pezizomycotina; Class Sordariomycetidae; Subclass Hypocreomycetidae; Order Hypocreales; Family Nectriaceae; Genus Gibberella. Host range:The pathogen is capable of causing head blight or 'scab' on wheat (Triticum), barley (Hordeum), rice (Oryza), oats (Avena) and Gibberella stalk and ear rot disease on maize (Zea). The fungus also may infect other plant species without causing disease symptoms. Other host genera cited for Gibberella zeae or F. graminearum sensu lato (see below) are Agropyron, Agrostis, Bromus, Calamagrostis, Cenchrus, Cortaderia, Cucumis, Echinochloa, Glycine, Hierochloe, Lolium, Lycopersicon, Medicago, Phleum, Poa, Schizachyrium, Secale, Setaria, Sorghum, Spartina and Trifolium. Disease symptoms and signs:For wheat, brown, dark purple to black necrotic lesions form on the exterior surface of the florets and glume (). Although these lesion symptoms sometimes are referred to as scab, they are not formally related to the hyperplasia and hypertrophic epidermal growth associated with other scab diseases such as apple scab. Peduncles immediately below the inflorescence may become discoloured brown/purple. With time, tissue of the inflorescence often becomes blighted, appearing bleached and tan, while the grain within atrophies. Awns often become deformed, twisted and curved downward. In barley, infections are not always readily apparent in the field. Infected spikelets may show a browning or water-soaked appearance. Infected barley kernels show a tan to dark brown discolouration that can be similar to that caused by other kernel blighting organisms. During prolonged wet periods, pink to salmon-orange spore masses of the fungus are often seen on infected spikelets, glumes and kernels in both wheat and barley. For maize ear rot, infection occurs by way of colonizing silk and thus symptoms first appear at the ear apex. White mycelium, turning pink to red with time, colonizes kernels and may progress basipetally, covering the entire ear.

And Atriplex canescens (Pursh) Nutt. AN - 17774347; 6148235 AB - Black grama (Bouteloua eriopoda) and fourwing saltbush (Atriplex canescens) are important grass and shrub species in arid rangelands of the northern Chihuahuan Desert. They are naturally colonized by dark septate endophytic fungi that cannot be eliminated by seed disinfestation. Plants were regenerated from both species and appeared to be fungus-free in axenic cultures. Analysis of callus and regenerated plants of both species using dual staining with light and scanning electron microscopy revealed fungal endophytes intrinsically associated with cells, roots and leaves of regenerated plants that are also associated with native plants. Fungal layers and biofilms prevent direct exposure of callus, root or leaf tissues to the external environment. Micropropagation is a valuable tool for identifying key fungal endophytes that enhance drought tolerance in native desert plants.

AN - 17774298; 6108810 AB - A polyphasic taxonomic evaluation of presumptive strains representative of the genus Glycomyces held within the Agricultural Research Service Culture Collection resulted in the discovery of three novel species. Analysis of the whole cell sugar content of these novel species, as well as of two species presently assigned to the genus, revealed that the whole cell sugar pattern was different from that reported in the formal description of the genus Glycomyces. The sugars present in all strains studied included ribose, xylose, mannose and galactose rather than xylose and arabinose as reported in the original description of the genus. Moreover, the menaquinone patterns observed for the novel species also deviated from the original genus description. The formal description of the genus Glycomyces is emended to reflect these new data. The novel species proposed and described are Glycomyces algeriensis sp. nov. (type strain NRRL B-16327 super(T)=DSM 44727 super(T)), Glycomyces arizonensis sp. nov. (type strain NRRL B-16153 super(T)=DSM 44726 super(T)) and Glycomyces lechevalierae sp. nov.

There were no significant differences between the annual NO sub(3) load estimates using non-intensive sampling methods and the actual NO sub(3) loads. However, maximum daily NO sub(3) loads were estimated less accurately than annual loads. The ability to estimate baseline NO sub(3) loads fairly accurately with non-intensive concentration data is attributed to the small fluctuation in NO sub(3) concentrations over flow and time, particularly during storms. By contrast, suspended sediment exports determined by any of the non-intensive methods varied significantly and widely from and compared poorly to the actual exports for both daily and annual methods. Weekly sampling better approximated actual annual exports, but there were no significant statistical differences among weekly, monthly, and quarterly estimates. Suspended sediment concentrations varied widely within and among storm events, so that accurate estimates of total annual or maximum daily loads could not be obtained from infrequent sampling.

Amplified fragment length polymorphism (AFLP), model-based Bayesian clustering, and other methods of hypothesis testing were used to investigate genetic diversity and population structure among 565 P. spicata plants from 82 localities representing much of the species distribution. Comparisons with four Asiatic Pseudoroegneria species and two North American Elymus wawawaiensis accessions demonstrate cohesiveness in P. spicata. However, P. spicata genotypes group by locality and geographic region based on genetic distance analysis. Average DNA polymorphism among P. spicata localities was significantly correlated (r = 0.58) with geographical distance. The optimum Bayesian cluster model included 21 P. spicata groups, indicating that dispersal among sampling locations was not sufficient to group genotypes into one unstructured population. Approximately 18.3% of the DNA polymorphism was partitioned among the 21 regional groups, 14.9% among localities within groups, and 66.8% within accessions. Average DNA polymorphism among Bayesian groups was correlated (r = 0.53) with the average geographic distance among Bayesian groups, which partly reflects isolation by distance. However, conspicuous regional boundaries were discernable among several divergent genetic groups.

L. monocytogenes is usually characterized by serotyping and is subtyped by using pulsed-field gel electrophoresis (PFGE) or ribotyping. DNA microarrays provide an alternative means to resolve genetic differences among isolates, and unlike PFGE and ribotyping, microarrays can be used to identify specific genes associated with strains of interest. Twenty strains of L. monocytogenes representing six serovars were used to generate a shotgun library, and subsequently a 629-probe microarray was constructed by using features that included only potentially polymorphic gene probe sequences. Fifty-two strains of L. monocytogenes were genotyped by using the condensed array, including strains associated with five major listeriosis epidemics. Cluster analysis of the microarray data grouped strains according to phylogenetic lineage and serotype. Most epidemiologically linked strains were grouped together, and subtyping resolution was the same as that with PFGE (using AscI and ApaI) and better than that with multilocus sequence typing (using six housekeeping genes) and ribotyping. Additionally, a majority of epidemic strains were grouped together within phylogenetic Division I. This epidemic cluster was clearly distinct from the two other Division I clusters, which encompassed primarily sporadic and environmental strains. Discriminant function analysis allowed identification of 22 probes from the mixed-genome array that distinguish serotypes and subtypes, including several potential markers that were distinct for the epidemic cluster. Many of the subtype-specific genes encode proteins that likely confer survival advantages in the environment and/or host.

However, there has been limited investigation relating disease control efficacy to various compost tea production methods, particularly compost tea produced with active aeration and additives to increase microbial population densities in compost tea. Aerated compost tea (ACT) and nonaerated compost tea (NCT), produced with or without additives, was investigated for the suppression of damping-off of cucumber caused by Pythium ultimum. Compost tea was used to drench soilless container medium inoculated with P. ultimum; effect on damping-off ranged from not suppressive to consistently suppressive depending on the method used to produce the tea. The most consistent formulation for damping-off suppression was ACT produced with kelp and humic acid additives. Producing ACT with a molasses-based additive inconsistently suppressed damping-off; evidence suggests that residual nutrients can interfere with disease suppression. Heating or diluting compost tea negated suppression. Across all compost tea samples, there was no significant relationship of bacterial populations, measured as active cells, total cells, or CFU, to disease suppression. However, for all ACT produced without the molasses-based additive, there was a threshold of bacterial population density (6 log sub(10) active cells per ml, 7.48 log sub(10) total cells per ml, or 7 log sub(10) CFU per ml) above which compost teas were suppressive.

Microbial selection procedures that require prospective biocontrol agents to possess both efficacy and amenability to production in liquid culture increase the likelihood of selecting agents with enhanced commercial development potential. Scale-up of biomass production procedures must optimize product quantity without compromise of product efficacy or amenability to stabilization and formulation. Formulation of Bacillus spp. for use against plant pathogens is an enormous topic in general terms but limited in published specifics regarding formulations used in commercially available products. Types of formulations include dry products such as wettable powders, dusts, and granules, and liquid products including cell suspensions in water, oils, and emulsions. Cells can also be microencapsulated. Considerations critical to designing successful formulations of microbial biomass are many fold and include preserving biomass viability during stabilization, drying, and rehydration; aiding biomass delivery, target coverage, and target adhesion; and enhancing biomass survival and efficacy after delivery to the target. Solutions to these formulation considerations will not necessarily be compatible. Data from several biocontrol systems including the use of B. subtilis OH 131.1 (NRRL B-30212) to reduce Fusarium head blight of wheat are used to illustrate many of these issues. Using our recently described assay for efficiently evaluating biomass production and formulation protocols, we demonstrate the effectiveness, in vitro, of UV protectant compounds lignin (PC 1307) and Blankophor BBH in reducing OH 131.1 morbidity when cells were exposed to UV light from artificial sunlight.

Expression of LEE2, LEE3, and tir is positively regulated by ler, a gene located in LEE1. Transcriptional regulation of the esp operon (LEE4), however, is not well defined. Transposon mutagenesis was used to identify transcriptional regulators of the esp operon by screening for mutants with increased beta-galactosidase activity in an EHEC O157:H7 strain harboring an esp::lac transcriptional fusion. All mutants with significant increases in beta-galactosidase activity had transposon insertions in hha (hha::Tn). Specific complementation of the hha::Tn mutation with a plasmid-encoded copy of hha reduced beta-galactosidase activity to the level expressed in the parental esp::lac strain. Purified Hha, however, bound poorly to the esp promoter, suggesting that Hha might repress the transcription of a positive regulator of esp. Transposon mutagenesis of a delta hha esp::lac strain expressing elevated levels of beta-galactosidase resulted in ler mutants with reduced beta-galactosidase activity. Purified Hha bound to the ler promoter with a higher affinity, and complementation of a delta hha mutation in a delta hha ler::lac strain repressed beta-galactosidase activity to the level expressed in a ler::lac strain. A positive regulatory role of ler in esp expression was demonstrated by specific binding of Ler to the esp promoter, reduced expression of beta-galactosidase in delta ler esp::lac strains with and without hha, and severalfold-increased transcription of ler and espA in strains lacking hha. These results indicate that hha-mediated repression of ler causes reduced expression of the esp operon.

This microsymbiont is known to secrete at least five nodulation outer proteins (Nops) in response to flavonoid induction. Some of these Nops have been shown to be secreted by TTSS in this symbiotic bacterium. We have isolated and purified an 18-kDa extracellular protein from flavonoid-induced cultures of USDA257. The N-terminal amino acid sequence of this purified protein was identical to the published sequence of the soybean cultivar-specificity protein, NopB (formerly NolB). Inactivation of rhcN, which encodes an ATPase, abolished secretion of NopB. Similarly, a nonpolar nopB deletion mutant was compromised in its ability to secrete several Nops. A construct containing the coding region of nopB under control of a T7 promoter was expressed successfully in Escherichia coli and, subsequently, the recombinant NopB was purified by nickel-affinity column chromatography. Polyclonal antibodies raised against purified recombinant NopB were used in Western blot analysis to demonstrate the association of NopB with pilus-like surface appendages. Deletion analysis indicated that the first 33 N-terminal residues of NopB were necessary and sufficient to mediate the secretion of a green fluorescent protein reporter. Introduction of plasmid-borne extra copies of nopB into USDA257 resulted in lower accumulation of native NopB. We also show that USDA257 and its nonpolar nopB deletion mutant exhibited discernible differences in their ability to nodulate legume hosts.

The hypothesis tested was that root collar excavation, when timed in early stages of root collar infection, may cause mycelial fans of the pathogen Armillaria mellea to recede from the root collar before severe disease results from vascular tissue decay. In vineyard N1, excavation significantly increased yield and cluster weight of symptomatic grapevines; symptomatic-excavated grapevines had the same high mean cluster weight as healthy grapevines, and there were no significant effects of excavation on yield or pruning weight of healthy grapevines. In vineyard K1, where excavated root collars frequently refilled with soil, excavation had no significant effects on yield or pruning weight of symptomatic grapevines, and significantly reduced pruning weight and shoot weight of healthy grapevines. Reexamination in March 2004 revealed that mycelial fans had receded from root collars of symptomatic-excavated grapevines, but remained on root collars of symptomatic-nonexcavated grapevines. Root collar excavation appears to be a promising cultural approach for control of Armillaria root disease, as long as excavated root collars are kept clear of soil.

Much has been learned from previous research, although site- specific data from both before and after wildfire are rare. The Entiat Experimental Forest (EEF) in central Washington State provides such a hydrologic record. In August 1970 a severe wildfire occurred following 10 years of stream gauging as part of a controlled land use experiment. A modified data collection program continued through 1977. Existing data from the EEF are available on the internet. Data housed at the site include downloadable daily discharge, air temperature, humidity, precipitation, water temperature, 10-m DEMs, watershed boundaries, and gauge locations. These data are an archive for assessment of hydrologic response and model formulation, calibration, and testing. The EEF is being reinstrumented to investigate recovery from effects of the 1970 fire on water quantity, quality, and flow regime.

In this study, experiments were conducted to determine the capacity of five different wheat cultivars to enhance resident populations and support introduced strains of 2,4-diacetylphloroglucinol (2,4-DAPG)-producing fluorescent pseudomonads, a group of bacteria known to provide biological control of several soilborne diseases. When soils were cropped with three successive 28-day growth cycles of wheat, the 2,4-DAPG-producing strains were consistently recovered from the rhizosphere of the cultivar Lewjain, and commonly were present at populations higher than those recovered from other wheat cultivars. Based on restriction fragment length polymorphism and sequence analyses of phlD, a key gene involved in 2,4-DAPG production, two previously undefined phlD+ genotypes, referred to as genotypes PfZ and PfY, were discovered. Wheat cultivar Lewjain was the primary source of genotype PfY while cultivar Penawawa yielded the majority of genotype PfZ. Based on 16S rDNA sequence analysis, both new phlD genotypes were classified as P. fluorescens. Comparison of the rhizosphere competence of 2,4-DAPG-producing P. fluorescens Q2-87 (genotype B) and P. fluorescens LR3-A28 (genotype PfY) showed that both strains persisted at similar populations in the rhizosphere of all cultivars tested over a 30 day period when introduced as a seed inoculant. However, when strain LR3-A28 was applied as a soil inoculant, this strain was recovered at higher populations from the rhizosphere of wheat cultivar Lewjain than from the rhizospheres of two other cultivars. No cultivar effects were shown for strain Q2-87. Collectively, these results add further to evidence indicating a degree of specificity in interactions between plant cultivars and specific members of the saprophytic microbial community. Furthermore, as 2,4-DAPG-producing fluorescent Pseudomonas spp. have a central role in the spontaneous reduction in severity of take-all disease of wheat in response to continuous wheat monoculture, we postulate that the use of specific cultivars, such as Lewjain, which possess a superior capacity to enhance resident soil populations of these bacteria may have potential to reduce the length of the monoculture period required to induce natural suppressiveness of soils toward this disease.

Major losses in yield result from biotic and abiotic stresses that include diseases such as Cassava Mosaic Disease (CMD) and Cassava Bacterial Blight (CBB), drought, and acid soils. Additional losses also occur from deterioration during the post-harvest storage of roots. To help cassava breeders overcome these obstacles, the scientific community has turned to modern genomics approaches to identify key genetic characteristics associated with resistance to these yield-limiting factors. One approach for developing a genomics program requires the development of ESTs (expressed sequence tags). To date, nearly 23000 ESTs have been developed from various cassava tissues, and genotypes. Preliminary analysis indicates existing EST resources contain at least 6000-7000 unigenes. Data presented in this report indicate that the cassava ESTs will be a valuable resource for the study of genetic diversity, stress resistance, and growth and development, not only in cassava, but also other members of the Euphorbiaceae family.

Fumigants are highly volatile, and approaches to reduce atmospheric emissions are required to protect human and environmental health. Application of fumigants through drip irrigation has been proposed as a means to decrease fumigant emissions, improve fumigant distribution in soil, and minimize worker exposure. These experiments were conducted to investigate the effect of the configuration of the drip system on the volatilization and distribution of the fumigants 1,3-dichloropropene (1,3-D), propargyl bromide (PrBr), and methyl isothiocyanate (MITC) in bedded systems. Results indicated that changing the drip emitter spacing and using multiple drip lines in each bed had little effect on the emissions and distribution of any fumigant. Increasing the depth of application from 15 to 30 cm reduced volatilization of MITC by similar to 20 to >90%; emissions were reduced due to a decrease in the flux from the bed top, and deeper injection did not change the amount of fumigant volatilized from the bed side slope and furrow. Increasing the application depth resulted in a slight decrease in the rate of fumigant dissipation in soil, indicating the potential for some improvement in pest-control efficacy with deeper application.

AN - 67075175; 15553161 AB - Low-pressure gas chromatography-mass spectrometry (LP-GC-MS) using a quadrupole MS instrument was further optimized and evaluated for the fast analysis of multiple pesticide residues in food crops. Performance of two different LP-GC-MS column configurations was compared in various experiments, including ruggedness tests with repeated injections of pesticides in matrix extracts. The tested column configurations employed the same 3 m x 0.15 mm i.d. restriction capillary at the inlet end, but different analytical columns attached to the vacuum: (A) a 10 m x 0.53 mm i.d., 1 microm film thickness RTX-5 Sil MS column; and (B) a 10 m x 0.25 mm i.d., 0.25 microm film thickness DB-5MS column. Under the optimized conditions (compromise between speed and sensitivity), the narrower analytical column with a thinner film provided slightly (<1.1-fold) faster analysis of <5.5 min separation times and somewhat greater separation efficiency. However, lower detection limits for most of the tested pesticides in real extracts were achieved using the mega-bore configuration, which also provided significantly greater ruggedness of the analysis (long-term repeatability of analyte peak intensities, shapes, and retention times). Additionally, the effect of the increasing injection volume (1-5 microl) on analyte signal-to-noise ratios was evaluated. For the majority of the tested analyte-matrix combinations, the increase in sensitivity caused by a larger injection did not translate in the same gain in analyte detectability. Considering the costs and benefits, the injection volume of 2-3 microl was optimal for detectability of the majority of 57 selected pesticides in apple, carrot, lettuce, and wheat extracts.

Our objective was to assess the influences of ownership and environment on changes in forest vegetation from post-settlement historical to recent times in the central Coast Range of Oregon. We evaluated land cover types on 1475 20m plots, using scanned, geo-referenced historical (1939) and recent (1993) aerial photos. The amount of older conifer cover declined by 63% relative to its former amount, from 36 to 13% of the landscape, during the 54-year period. Dominant ownership of older conifer stands shifted from industrial private to Forest Service lands. Younger conifer stands showed the greatest expansion in cover, increasing more than two-fold, from 21 to 44% of the landscape. Shrub and hardwood cover declined by 16%, from 31 to 25% of the landscape. Shrubs and hardwoods occurred at lower slope positions and closer to streams at the end of the period than at the beginning. Ownership was not an important determinant of the presence of large and very large conifer cover or shrub and hardwood cover in 1939, but was a very important factor affecting the presence of these cover types in 1993. Landscape transitional pathways were distributed among many types and no single transitional pathway was dominant. Even the most stable cover types (hardwood trees and herbs) had low absolute stability, with over 65% of their plots changing to another cover type by 1993. Our research indicates that the importance of ownership as a factor affecting the type of vegetation cover present has increased greatly during this time, whereas the relative influence of environment has lessened considerably. Land owners in the Oregon Coast Range have altered the cover and distribution of vegetation in diverse ways, changing the landscape to one dominated by young conifers, shifting the distribution of younger successional shrubs and hardwoods toward streams, and restricting the location of older coniferous stands to particular ownerships and site types.

Our objective was to quantify the relationship between the abundance and diversity of ectomycorrhizal fungal sporocarps in the soil and in the diets of northern flying squirrels (Glaucomys sabrinus) in low-elevation forests of the eastern Washington Cascades. We randomly sampled four stands each of three cover types: dry open ponderosa pine, mesic young mixed-conifer forest, and mesic mature mixed-conifer forest. We sampled the soil for hypogeous sporocarps during the spring of 1999 and 2000. We collected fecal pellets from 318 flying squirrels live-trapped during the fall of 1997-2000. We sampled 2400m super(2) of soil surface and found truffles in 40% of 600 plots. Total biomass collected was 609g. Spring truffle biomass on a kg/ha basis averaged 1.72 in open pine, 3.56 in young, and 4.11 in mature forest. Twenty-two species were collected across all cover types, with all but three species belonging to the Basidiomycotina. Eleven dominant species accounted for 91-94% of truffle biomass in each cover type. Four dominant species accounted for 60-70% of spring truffle biomass: Gautieria monticola, Hysterangium coriaceum, Rhizopogon parksii, and R. vinicolor. Truffle assemblages, richness and total biomass differed among cover types: richness and biomass were highest in young and mature mixed-conifer forest, and lowest in open ponderosa pine forest. Fall squirrel diets were composed of 23 genera or groups of fungi, plus about 22% plant material. Rhizopogon was the most abundant genus in the diet, followed by plant material, then Gautieria, Leucogaster, Alpova, and Hysterangium. Diets in different cover types were similar in the composition, richness, evenness, and the ratio of fungus to plant material. Diet richness varied over the study period. Nineteen truffle genera were detected in fall fecal samples versus 12 in spring soil samples. Management of low-elevation dry forest to maintain or restore stable fire regimes might reduce truffle diversity at stand scales by simplifying stand composition and structure; but, such management might increase long-term beta and landscape truffle diversity and persistence by reducing the occurrence of high-intensity fires and stabilizing inherent fire disturbance regimes.

We studied their affect and their interaction by measuring the composition, richness, cover, physical stature, and reproductive potential of vascular plants in the understory of three thinned (uneven-aged, even-aged, managing for old-growth characteristics) and two unthinned (second-growth, old-growth) forests dominated by sugar maple (Acer saccharum Marsh.) in western Upper Michigan. Based on measurements taken five years after deer exclosures were established, we found consistent and strong statistical differences in species richness and percent cover related to forest harvest but not to deer browse. Percent cover of the understory vegetation showed weakly significant interactions between deer browse and forest harvest. Thinned forests had a greater average richness and cover of graminoid species, average cover of wild red raspberry (Rubus strigosus L.) and sugar maple compared to unthinned forests. Measurements of plant morphology and the frequency of flowering and fruiting were more sensitive indicators of deer browse than community measurements such as richness and cover. Based on measures of physical stature and reproductive potential, sugar maple, red-berried elder (Sambucus racemosa L.), bluebead-lily (Clintonia borealis (Aiton) Raf.), small Solomon-seal (Polygonatum pubescens (Willd.) Pursh.), false Solomon-seal (Smilacina racemosa (L.)

A better understanding of the interaction between forest harvest and deer browse and their effect on community composition and structure is critical to maintaining and enhancing biodiversity in managed northern hardwood forests.

Lawson var. ponderosa) forests were measured to guide the design of restoration prescriptions. The age, size structure, and the spatial patterns were investigated in old-growth ponderosa pine forests at three protected study areas east of the crest of the Cascade Range: Metolius Research Natural Area and Pringle Butte Research Natural Area in central Oregon and Blacks Mountain Experimental Forest in northern California. The three study areas represented sites characterized by deep accumulations of pumice from Cascade volcanism. All stems >=15cm in height (minimum height of an established seedling) were mapped and measured on a total of 27 1-ha plots. The distribution of trees within each individual plot was investigated by second-order spatial analysis with Ripley's K(d) function, and then evaluated across each study area with functional data analysis. Coarse woody debris was sampled by using the strip-plot method to determine log density, mean log size, volume, and cover. The oldest trees were 618 years at Metolius, 613 years at Pringle Butte, and 330 years at Blacks Mountain. Stands were multi-aged, with as many as 16 cohorts at Metolius and 22 cohorts at Pringle Butte. Density of live old-growth ponderosa pine in the upper canopy ranged from 34 to 94 treesha super(-) super(1) at Metolius, 35 to 79 treesha super(-) super(1) at Pringle Butte, and 15 to 73 treesha super(-) super(1) at Blacks Mountain; the differences between study areas were not significant, resulting in an overall mean density of 50 +/- 3.5 live old-growth treesha super(-) super(1). Mean diameters of these old-growth trees did not differ among the three study areas; the overall mean was 60.0 +/- 1.55cmdbh. Large dead ponderosa pines (overall mean diameter 61.7 +/- 4.33cm) were a common feature at all three study areas; the overall mean density was 9.0 +/- 0.97 treesha super(-) super(1). Ripley's K(d) analysis of spatial point patterns using upper canopy trees revealed significant departure from randomness in 24 of the 27 plots. Functional data analysis of the spatial relationship of all sample plots by study area revealed two strong patterns. At scales of 1.2 =< d =< 2.6m at Metolius and 1.6 =< d =< 8.4m at Blacks Mountain, the deviation from random was not significant, suggesting the distribution of old-growth trees was random. More important, significant positive deviation from complete spatial randomness at larger scales at Metolius and Blacks Mountain suggested a clumped distribution. Maximum radii of the clumps were about 22.5m in diameter at Metolius and about 24m in diameter at Blacks Mountain. In contrast, old-growth trees at Pringle Butte were randomly distributed. Density of logs at Metolius and Pringle Butte was 47.0 +/- 5.28logsha super(-) super(1), their mean large-end diameter was 37.6 +/- 2.41cm, the mean length of each log was 4.2 +/- 0.09m, the cumulative length of all logs averaged 512.9 +/- 78.12m, the total volume averaged 62.3 +/- 6.30m super(3)ha super(-) super(1), and the cover averaged 1.7 +/- 0.08%. A majority of the logs were in an advanced stage of decomposition, suggesting that they were in place for considerable time. These results are discussed in the context of reference conditions for restoration of ecosystem health and ecological integrity in eastside ponderosa pine forests.

To expand our knowledge of snag use by cavity-nesting birds in this region, we documented characteristics of snags with and without excavated cavities in mixed-conifer and ponderosa pine (Pinus ponderosa Dougl. ex Laws) forest in north-central Arizona. Snags were sampled in 113 square plots (1ha each) randomly located within a study area covering approximately 73,000ha across two National Forests. Density of snags was three times greater in mixed-conifer forest (n = 53 plots) than in ponderosa pine forest (n = 60 plots), but density of snags containing cavities and overall cavity density did not differ between forest types. In both forest types, snags containing cavities were larger in diameter and retained less bark cover than snags without cavities. Most cavities were in ponderosa pine and Gambel oak (Quercus gambelii Nutt.) snags, and most were in snags in advanced decay classes with broken tops. Our results are largely consistent with previous results from ponderosa pine forest, but differ from previous studies that documented heavy use of quaking aspen (Populus tremuloides Michaux) by cavity nesters in mixed-conifer forest. These results support management to protect and recruit large snags well distributed across the landscape. The relatively high use of ponderosa pine and Gambel oak snags in both forest types suggests that recruitment of large pine and oak snags should be emphasized, and previous studies suggest emphasizing aspen recruitment as well. This may require special management efforts in mixed-conifer forest. These species are relatively shade-intolerant seral species in this forest type, and are apparently declining in this forest type due to fire-suppression efforts and resultant patterns of ecological succession.

Traps were placed at the center, edge, and in the surrounding forest of each gap. Young gaps (~1 year) had large amounts of coarse woody debris compared to the surrounding forest, while older gaps (~6 years) had virtually none. The total abundance and diversity of wood-dwelling beetles (Buprestidae, Cerambycidae, Brentidae, Bostrichidae, and Curculionidae (Scolytinae and Platypodinae)) was higher in the center of young gaps than in the center of old gaps. The abundance was higher in the center of young gaps than in the surrounding forest, while the forest surrounding old gaps and the edge of old gaps had a higher abundance and diversity of wood-dwelling beetles than did the center of old gaps. There was no difference in wood-dwelling beetle abundance between gaps of different size, but diversity was lower in 0.13ha old gaps than in 0.26ha or 0.50ha old gaps. We suspect that gap size has more of an effect on woodborer abundance than indicated here because malaise traps sample a limited area. The predaceous beetle family Cleridae showed a very similar trend to that of the woodborers. Coarse woody debris is an important resource for many organisms, and our results lend further support to forest management practices that preserve coarse woody debris created during timber removal.

AN - 67281259; 15726812 AB - The sequence of the atDjC6 chaperone protein includes three potential nuclear localization signal (NLS) sequences (A-C) and three potential nuclear export signal (NES) sequences (X-Z). The subcellular localization of atDjC6 was studied by scanning laser confocal microscopy of chimera with the green-fluorescent protein (GFP) transiently expressed in tobacco BY-2 cells. The localization of the atDjC6::GFP chimera was coincident with that of the nuclear stain propidium iodide. Site-directed mutagenesis was used to verify the predicted NLS sequences. Each was individually fused to GFP and tested for protein localization. The individual NLS sequences were sufficient to direct partial nuclear localization of GFP, although the targeting information within NLS-B is apparently conformation sensitive. Site-directed mutagenesis of the NES sequences increased the amount of each chimera that was nuclearly localized, indicating a decrease in nuclear export. When any pair of NLS sequences were appended to GFP, the chimera were entirely nuclearly localized. Quantitative two-hybrid analysis was used to verify that the decoding of NLS sequence information involves interaction with the NLS-receptor protein importin-alpha. Each of the NLS sequences is flanked by a site of potential Ser phosphorylation, and recombinant atDjC6 could be phosphorylated in vitro. Mutagenesis of Ser residues to the P-Ser mimic Asp interfered with nuclear targeting, apparently by preventing recognition or binding by importin-alpha. Our results are consistent with a regulated nucleocytoplasmic localization of the atDjC6 chaperone protein.

AN - 67246380; 15636392 AB - Prevention of disease is a core public health mission. Food-borne illness is a major source of preventable morbidity and mortality. Each year, an estimated 76 million illnesses, 325,000 hospitalizations, and 5200 deaths due to food-borne illness occur in the United States. Research findings show that irradiating food can both greatly reduce illness from food-borne pathogens and extend food shelf life by delaying ripening, inhibiting spoilage, and minimizing contamination. However, because the food industry has historically been reluctant to sell irradiated foods, food irradiation remains an underutilized technology.

AN - 67108944; 15568337 AB - The application of azadirachtin to foliage of cantaloupes did not significantly reduce successful pollination by commercially managed honey bees, Apis mellifera L., as measured by numbers of foraging honey bees and yield. Similar results were obtained when the synthetic insecticide imidacloprid (used as a standard by cantaloupe growers) was applied to the soil. Fruit yield and quality, as a function of bee pollination, were statistically equal between the two treatments, and equal to that of the untreated control. The standard treatment of imidacloprid gave significantly better control than azadirachtin of one pest (cucumber beetle) early in the season. Fruit maturity was delayed in untreated plots, consistent with light insect pressure observed. These results indicate that an organically based insect control approach will not alter bloom acceptance and bee forager activity in cantaloupes.

AN - 67106694; 15568336 AB - The efficacy of a formic acid pad formulation was field tested for control of the honey bee parasitic mite Varroa destructor Anderson & Trueman in Florida and Texas. This pad formulation gave 39.8 +/- 11.1% control at the end of a 6-wk treatment period, which did not significantly differ from the initial sample date. Coumaphos treatment provided poor control (38.4 +/- 11.1%) over the 6-wk period, confirming reports of coumaphos resistance in the region. Under relatively warm winter conditions in southern Texas, formic acid caused mortality of developing eggs and brood. If resistance by V. destructor to the two acaricides registered for its control in the United States continues, the formic acid pad could provide an alternative compound to use as part of an integrated pest management approach.

AN - 67015707; 15508637 AB - Acidified sodium chlorite (ASC) spray was evaluated at decreased dosages and application rates to determine its efficacy for reducing bacterial contamination on boneless beef trimmings used for production of raw ground beef products while maintaining desirable consumer qualities in the finished ground beef products. Two different applications of ASC (600 ppm applied at a rate of 1.3 oz/lb and 300 ppm applied at a rate of 1 oz/lb) were used to treat boneless beef trimmings before grinding. The effect of ASC treatment on 50/50 lean beef trimmings was greater than on 90/10 trimmings. ASC at 600 ppm reduced both the aerobic plate counts (APC) and Enterobacteriaceae counts (EBC) by 2.3 log CFU/g on 50/50 trimmings, whereas treatment with 300 ppm ASC reduced APC and EBC of 50/50 trimmings by 1.1 and 0.7 log CFU/g, respectively. Ground beef formulations of 90/10 and 73/27 were produced from the treated boneless beef trim and packaged in chubs and in modified atmosphere packaging. The efficacy of ASC spray treatment to inhibit APC and EBC over the shelf life of each ground beef product was monitored. The APC and EBC in ground beef chubs were reduced by 1.0 to 1.5 log CFU/g until day 20. The APC and EBC for products in modified atmosphere packaging were reduced 1.5 to 3.0 log CFU/g throughout their shelf life. Both decreased dosages of ASC were equally effective on 90/10 lean ground beef, but the 300 ppm ASC treatment was slightly better at reducing the EBC of 73/27 ground beef. The organoleptic qualities (color, odor, and taste) of the ground beef products treated with 300 ppm ASC were found to be superior to those treated with 600 ppm ASC. Our results indicated that decreased dosages of ASC reduce contamination and lengthen the shelf life of ground beef. Furthermore, the 300 ppm ASC treatment reduced bacterial counts while maintaining desirable organoleptic ground beef qualities.

AN - 67014109; 15510548 AB - Atmospheric ammonia inhibits broiler performance. Quantified effects are based on older genetic stock with a BW of 2000 g at 7 wk. In contrast, modern genetic stock reaches 3200 g at 7 wk of age. To assess the impact on present day broilers, 2 trials were conducted exposing male broilers to graded levels (0, 25, 50, and 75 ppm) of aerial ammonia from 0 to 4 wk of age. Sixty, 1-d-old chicks were placed in environmentally controlled chambers, weighed weekly as a group, and processed with yield determined at 7 wk of age. Final BW was significantly depressed by 6 and 9% for the 50 and 75 ppm concentrations of ammonia as compared with 0 ppm. Also, mortality was significantly greater at the 75 ppm ammonia concentration, 13.9% compared with 5.8% for the 0 ppm treatment. Percentage yield of deboned meat per bird decreased slightly with increasing exposure to ammonia but was not statistically significant. Although current genetic stock reaches growout weights that are approximately 60% greater than those 2 decades ago, the relative quantified effects of ammonia exposure were similar. Additionally, statistical analysis of the results provided a simple equation, presented herein, for predicting the decline in BW of male broilers after exposure to ammonia.

AN - 66972794; 15484964 AB - Broom snakeweed (Gutierrezia sarothrae) is the most widespread range weed in North America. We attempted to positively condition cattle to graze broom snakeweed to create a biological tool to decrease the competitive ability of snakeweed in a plant community. Fifteen yearling heifers were divided into three treatment groups receiving different supplements: 1) cornstarch, 2) starch with ground snakeweed, and 3) a control (no supplements). Heifers were fed fresh snakeweed, and then were gavaged with the respective supplements to provide positive feedback to enhance their acceptance of snakeweed. The starch group consumed more snakeweed in the pen conditioning trial (P = 0.02). The starch and control groups were then taken to the field for two grazing trials. In the spring grazing trial, there was no snakeweed consumed in the free-ranging part of the trial; however, when the pasture size was decreased, the heifers started to consume snakeweed as alternative forages became less abundant. In the second small pasture trial, heifers in the positively conditioned group consumed more snake-weed than those in the control group (16 vs. 5% of bites, P < 0.001). In the fall grazing trial, little snakeweed was consumed in the free-ranging part of the trial. When the pasture size was decreased, both positively conditioned and control groups increased snakeweed consumption up to 35% of bites. In the small pastures of both the spring and fall grazing trials, 36 to 59% of snakeweed plants were grazed. Cattle can be forced to graze snake-weed in a short-duration, high-intensity grazing strategy.

AN - 66907117; 15386117 AB - Acetylenic phenols and a chromene isolated from the grapevine fungal pathogen Eutypa lata were examined for mode of toxicity. The compounds included eutypine (4-hydroxy-3-[3-methyl-3-butene-1-ynyl] benzyl aldehyde), eutypinol (4-hydroxy-3-[3-methyl-3-butene-1-ynyl] benzyl alcohol), eulatachromene, 2- isoprenyl-5-formyl-benzofuran, siccayne, and eulatinol. A bioassay using the yeast Saccharomyces cerevisiae showed that all compounds were either lethal or inhibited growth. A respiratory assay using 2,3,5-triphenyltetrazolium (TTC) indicated that eutypinol and eulatachromene inhibited mitochondrial respiration in wild-type yeast. Bioassays also showed that 2- isoprenyl-5-formyl-benzofuran and siccayne inhibited mitochondrial respiration in the S. cerevisiae deletion mutant vph2Delta, lacking a vacuolar type H (+) ATPase (V-ATPase) assembly protein. Cell growth of tsa1Delta, a deletion mutant of S. cerevisiae lacking a thioredoxin peroxidase (cTPx I), was greatly reduced when grown on media containing eutypinol or eulatachromene and exposed to hydrogen peroxide (H(2)O(2)) as an oxidative stress. This reduction in growth establishes the toxic mode of action of these compounds through inhibition of mitochondrial respiration.

AN - 66893820; 15378649 AB - Many studies have correlated the consumption of soy-rich diets with a decreased risk of developing hormone-dependent cancers, including prostate cancer. Genistein is a candidate prostate cancer preventive phytochemical found at high levels in soybean and soy foods. To better understand the molecular mechanisms underlying the beneficial effects of genistein on prostate cancer prevention, we used a DNA microarray approach to examine the effects of genistein at concentrations in the physiologic range on global gene expression patterns in androgen-responsive cancer cells. Microarray analyses were performed on androgen-responsive LNCaP human prostate cancer cells exposed to 0, 1, 5, or 25 microM genistein. We found a concentration-dependent modulation of multiple cellular pathways that are important in prostate carcinogenesis. Interestingly, the androgen receptor (AR)-mediated pathways, in particular, appeared to be modulated by genistein at the lowest concentrations. Based on these results, we propose that the regulation of AR-mediated pathways is potentially the most relevant chemopreventive mechanism for genistein administered at physiologic levels.

AN - 66879047; 15367135 AB - Hydrilla (Hydrilla verticillata L.f. Royle) was introduced to the surface water of Florida in the 1950s and is today one of the most serious aquatic weed problems in the USA. As a result of concerns associated with the applications of pesticides to aquatic systems, fluridone is the only USEPA-approved chemical that provides systemic control of hydrilla. After a decrease in fluridone's efficacy at controlling hydrilla, 200 Florida water bodies were sampled to determine the extent of the problem and the biological basis for the reduced efficacy. Our studies revealed that hydrilla phenotypes with two- to six-fold higher fluridone resistance were present in 20 water bodies. Since fluridone is an inhibitor of the enzyme phytoene desaturase (PDS), the gene for PDS (pds) was cloned from herbicide-susceptible and -resistant hydrilla plants. We report for the first time in higher plants three independent herbicide-resistant hydrilla biotypes arising from the selection of somatic mutations at the arginine 304 codon of pds. The three PDS variants had specific activities similar to the wild-type enzyme but were two to five times less sensitive to fluridone. In vitro activity levels of the enzymes correlated with in vivo resistance of the corresponding biotypes. As hydrilla spread rapidly to lakes across the southern United States in the past, the expansion of resistant biotypes is likely to pose significant environmental challenges in the future.

AN - 66836922; 15341913 AB - The aflT gene resides between the polyketide synthase gene pksA and the P450-encoding cypA gene in the aflatoxin gene cluster of Aspergillus parasiticus. It is a single copy gene in the genome of A. parasiticus SRRC 2043 and SU-1 and was also found at the same relative position in the genome of Aspergillus flavus isolates. The predicted AFLT protein contained 14 transmembrane domains and had various degrees of the amino acid identity (34-56%) to fungal transporters belonging to the major facilitator superfamily. Targeted deletion of aflT in A. parasiticus SU-1 yielded transformants that were morphologically similar to SU-1. These aflT-deleted mutants produced and secreted aflatoxins comparable to the parental strain although they lost the production of the aflT transcript. Real-time RT-PCR analysis showed that the expression of aflT was controlled neither by the aflatoxin pathway-specific activator AFLR nor by the co-activator AFLJ, which differed from the regulation of the aflatoxin biosynthetic genes pksA, nor1, ver1, and omtA.

Field indicators of hydric soils in the United States, Version 4.0. In: G. W. Hurt et al. (Ed.), United States Department of Agriculture-NRCS, Fort Worth, TX], are useful, but in some cases, they can be subjective, difficult to recognize, or time consuming to assess. Magnetic susceptibility (MS) measurements, acquired rapidly in the field with a portable meter, have great potential to help soil scientists delineate and map areas of hydric soils more precisely and objectively. At five sites in Illinois (from 5 to 15 ha in area) with contrasting soil types and glacial histories, the MS values of surface soils were measured along transects, and afterwards mapped and contoured. The MS values were found to be consistently higher in well-drained soils and lower in hydric soils, reflecting anaerobic deterioration of both detrital magnetite and soil-formed ferrimagnetics. At each site, volumetric MS values were statistically compared to field indicators to determine a critical MS value for hydric soil delineation. Such critical values range between 22X10 (super -5) and 33X10 (super -5) SI in silty loessal or alluvial soils in Illinois, but are as high as 61X10 (super -5) SI at a site with fine sandy soil. A higher magnetite content and slower dissolution rate in sandy soils may explain the difference. Among sites with silty parent material, the lowest critical value (22X10 (super -5) SI) occurs in soil with low pH (4.5-5.5) since acidic conditions are less favorable to ferrimagnetic mineral neoformation and enhance magnetite dissolution. Because of their sensitivity to parent material properties and soil pH, critical MS values must be determined on a site specific basis. The MS of studied soil samples (0-5 cm depth) is mainly controlled by neoformed ultrafine ferrimagnetics and detrital magnetite concentrations, with a minor contribution from anthropogenic fly ash. Neoformed ferrimagnetics are present in all samples but, based on high chi (sub FD) % ( approximately 5% to 10%), are most prevalent in high pH Mollisols of northeastern Illinois. Scanning electron microscope images display significantly more detrital magnetite alteration in hydric soils, substantiating that reductive dissolution of magnetite (aided by microorganisms) is a primary cause for lower MS. Fly ash comprises 8-50% of the >5 mu m strongly magnetic particles and typically accounts for 5-15% of the total MS signal. The proportion of fly ash in >5 mu m strongly magnetic fractions is greater in hydric soils because of lower natural magnetite contents, possibly combined with historical topsoil accumulation in lower landscapes. Magnetic fly ash particles are also more altered in low MS soils, implying that significant magnetite dissolution can occur in less than 150 years.

This project is important to southeast Alaskan communities because limited land resources are forcing development of regional wetlands. This study was instigated by concerns that proposed modifications to a nearby rifle range using DRO-contaminated soil posed a potential risk to an anadromous fish-bearing stream 250 m from the site. Three pairs of peat columns were extracted from the rifle range for analysis, one pair along and two pairs across the natural bedding planes of the soil. One column in each pair was spiked with Pb and DRO and the other was used as a control. Approximately 1-year worth of water (171 cm) was passed through each column and leachate was collected at regular intervals. The results showed that substantial DRO transport only occurred along the bedding planes. Leads was surprisingly mobile, both along and across the bedding planes with estimated soil-water partition coefficients several orders of magnitude lower than commonly published values, probably because the peat was heavily Pb-loaded by lead from bullets and because the peat's acidic, organic-rich environment enhanced Pb mobility. The chemical outflow behavior agreed with a simple macropore transport model. These results underscore the need for caution when developing regional wetlands.

The Soil Water Assessment Tool (SWAT) is one of the watershed-scale simulation models within BASINS. Because of the critical nature of the TMDL process, it is imperative that BASINS and SWAT be adequately validated for regions on which they are being applied. BASINS and SWAT were tested using six years of hydrologic data from a 22 km super(2) subwatershed of the Little River in Georgia. Comparisons were made between water balance results obtained using high and low spatial resolution data as well as those obtained using default initial parameters versus those modified for existing groundwater conditions. In general, all scenarios simulated general trends in the observed flow data. However, for the years with lower precipitation, the total water yields simulated with the low spatial resolution data and the default initial conditions were overpredicted by up to 27% of the annual precipitation input. Total water yields simulated using the high spatial resolution input data were within 20% of the observed yields for each year of the assessment. Nash-Sutcliffe model efficiencies (E) for monthly total water yields were 0.80 using the high spatial resolution data with the modified initial conditions and 0.64 using the low spatial resolution data with the default initial conditions. While the model simulated general streamflow trends, discrepancies were observed between observed and simulated hydrograph peaks, time to peak, and hydrograph durations. A one-day time lag between the simulated and observed time to peak was the primary cause of large errors in daily flow simulations. Model modification and more extensive calibration may be necessary to increase the accuracy of the daily flow estimates for TMDL development.

We present biodiversity policy as an amalgam of four different conservation programs: salmon and aquatic habitat conservation, forest age-class management, endangered species protection, and large-scale conservation reserves. The results indicate substantial support for biodiversity protection, but significant differences in WTP across programs. Oregonians indicate the highest WTP for increasing the amount of forest devoted to achieving old-growth characteristics. On average, respondents indicate an annual household WTP of $ 380 to increase old-growth forests from 5% to 35% of the age-class distribution. Conversely, WTP for increasing conservation reserves peaks at $ 45 annually to double the current level to 20% of the landscape, whereas WTP is negative for any increase over 32% . We also find resistance to any change in conservation policy, which substantially offsets WTP for increases in all four conservation programs. FOR. SCI. 50(5):589- 602.

The objective is to improve guidance for forest managers deploying bark beetle antiaggregation pheromone sources to protect high-value forest stands. Data are shown from field studies in three forest canopies (oak-hickory, Quercus-Carya; lodgepole pine, Pinus contorta Dougl. ex Loud.; and ponderosa pine, Pinus ponderosa Dougl. ex Laws.) and include over 13,000 chemical tracer samples compiled into half-hour dispersion fields around a point source. Maximum normalized concentrations (/Q) at each arc distance for each sampling period were of similar order at 5 m from the tracer source in the three canopies, although the differences in maximum /Q between canopies increased with distance from the source. Plume dilution was highest in this study in the more open ponderosa pine canopy. A high-frequency tracer gas analyzer was also deployed to ascertain the structure of the gas plumes at 1 Hz. The high-frequency tracer data showed that the 30-minute average mean plumes are composites of narrow filamentous plumes. The near-field plumes in each canopy were strongly affected by changes in atmospheric stability, as wander range and meander frequency increased after the morning transition to an unstable boundary layer.

One example is jointed goatgrass, a winter annual grass invading winter wheat fields and not easily managed with conventional control tactics. A national research program was started in 1994 to develop jointed goatgrass management strategies. Involving more than 35 scientists with diverse scientific expertise, this national approach fostered cooperative research projects across 11 states. Research involved entomology, economics, plant breeding, plant physiology, genetics, and weed science, leading to successful management systems for jointed goatgrass. To help other scientists organize regional or national programs, we describe development and performance of the jointed goatgrass program as well as suggest ideas for possible improvement. Pivotal to the success of the program was a Steering Committee, whose role was to establish research priorities and coordinate research across the western United States.

(Coleoptera: Curculionidae) AN - 20111098; 8693845 AB - The black vine weevil Otiorhynchus sulcatus (F.) is the primary insect pest of field and container-grown woody ornamentals in the Pacific Northwest (PNW). These studies were conducted to determine the natural occurrence of soil-borne entomopathogens in PNW nursery soils and determine their virulence to black vine weevil. Soil samples were collected July-September of 2002 from field-grown woody ornamental nursery stock in Oregon, Washington, and Idaho. Sample collection in each state took place in the major nursery production areas. A total of 280 samples was collected (Oregon, 170; Washington, 50; Idaho, 60). Entomopathogens were isolated using insect baiting (nematodes and fungi) as well as semiselective media (fungi). Bacillus thuringiensis Berliner was isolated through sodium acetate selection. Soil-borne entomopathogenic fungi occur widely throughout the major nursery production areas in the PNW. The entomopathogenic fungi Metarhizium anisopliae (Metchnikoff) Sorokin, Beauveria bassiana (Balsamo) Vuillemin, and Paecilomyces tenuipes (Peck) Samson were isolated. An entomopathogenic nematode (Steinernema oregonense Liu and Berry) and B. thuringiensis were also isolated. Of the 30 fungal isolates bioassayed, all but one was pathogenic to last-instar black vine weevil. None of the B. thuringiensis isolates collected were pathogenic to adult black vine weevil. The S. oregonense that were collected only infected a single black vine weevil larvae at 15 and 22 degree C. Pathogens collected from this soil survey will serve as a source of potential biological control agents for black vine weevil.

A laboratory runoff study was designed and conducted to compare total loads with loads calculated from time-based sampling strategies. Total loads were measured by capturing all the runoff from 2.2 m super(2) Bermuda grass (Cynodon dactylon L. Pers.) sod plots with 5% slope and analyzing for NO sub(3)+NO sub(2)-N and NH sub(4)-N. Runoff samples were also manually collected on 1 min intervals during 2 h overland flow events. Total loads were compared to time-discrete and time-composite sampling strategies. The strategies included time-discrete sampling at 1, 2, 3, 4, 5, 10, 15, and 30 min and composite sampling that included 2, 3, 4, and 5 aliquots per composite sample based on the same time-discrete intervals. In addition, loads were also calculated from a composite sample derived from aliquots collected at 1, 2, 3, 4, 5, 6, 7, 8, 9, and 10 min intervals. The calculated load of NO sub(3)+NO sub(2)-N and NH sub(4)-N was not significantly different ( alpha = 0.05) from the total load when using time-discrete sampling at 1, 2, or 3 min time intervals. No significant difference ( alpha = 0.05) from the total load was found when using a composite approach with 2, 3, 4, or 5 aliquots collected at 1, 2, or 3 min time intervals or when using a composite sample with aliquots collected on a 1 min interval. To preserve the total load from plot-scale studies, more intensive sampling is required. The results from this study will facilitate the selection of time-based sampling strategies for plot-scale studies.

An important requirement for this strategy is that the toxin exists at a high effective dose for control of the target pest(s), so that heterozygous individuals in the population do not reach adulthood. Factors that cause reduced levels of toxin in the plant are a threat to this strategy. We quantified Cry1Ab from different areas of the maize, Zea mays L., leaf. In general, the distal tip of the V7 maize leaf had a higher concentration of Cry1Ab compared with the middle section of the V7 leaf, and the middle section of the developing V9 leaf had the lowest concentration of Cry1Ab. When these sections of maize tissue were fed to fall armyworm, Spodoptera frugiperda (J.E. Smith), and southwestern corn borer, Diatraea grandiosella Dyar, there was not a reduction in development or an increase in mortality with tissue that had higher concentrations of toxin. Another study tested the relative concentration of Cry1Ab between the white-yellow, yellow-green, and green portions of the developing ninth leaf within the maize whorl. There were differences in Cry1Ab concentration among these leaf areas. The green tissue had the highest concentration of toxin followed by the yellow-green and white-yellow tissues. Correlations between concentration of Cry1Ab and 5-d fall armyworm larval weights among the three leaf color profiles were all significant and negative, i.e., decreased concentration of Cry1Ab in the leaf tissue resulted in increased 5-d larval weights. There was 100% mortality to the southwestern corn borer larvae fed Cry1Ab maize leaf tissue. Differences in the amount of Cry1Ab in the developing V9 leaf profiles did not alter the absolute susceptibility of the southwestern corn borer to the toxin. In cotton, Gossypium hirsutum L., the amount of Cry1Ac was significantly lower in boll tips where flowers had remained attached compared with normal boll tips. Boll tips where the flowers remained attached are often the site where corn earworms, Helicoverpa zea (Boddie), penetrate Bt cotton bolls. This study demonstrated that, in two diverse plant species, tissue that has low chlorophyll content does not fully express Cry1A. Photosynthesis regulating factors related to mRNA transcription and translation should be studied for their effect on Cry1A production and insect control.

Wounding of leaves during harvest and ensiling results in browning of leaf tissues from activity of PPO on the o-diphenols. In association with browning, leaf proteins remain undegraded during ensiling, presumably due to PPO-generated o-quinone inhibition of leaf proteases. We cloned three red clover PPO cDNAs, PPO1, PPO2, and PPO3, from a leaf cDNA library. Sequence comparisons among the three red clover PPO clones indicated they are 87% to 90% identical at the nucleotide level (80%-83% amino acid identity). All three encode proteins predicted to localize to the chloroplast thylakoid lumen. RNA-blotting and immunoblotting experiments indicated PPO1 is expressed primarily in young leaves, PPO2 in flowers and petioles, and PPO3 in leaves and possibly flowers. We expressed mature PPO1 in Escherichia coli. A portion of the expressed protein was soluble and functional in an assay for PPO activity. We also expressed the red clover PPO cDNAs under the control of a constitutive promoter in alfalfa (Medicago sativa). The expressed red clover PPO proteins were active in alfalfa extracts as evidenced by o-diphenol-dependant extract browning and quantitative assays of PPO activity. Proteolysis in leaf extracts of alfalfa expressing red clover PPO1 was dramatically reduced in the presence of an o-diphenol compared to controls. Transgenic alfalfa expressing red clover PPO should prove an excellent model system to further characterize the red clover PPO enzymes and PPO-mediated inhibition of postharvest proteolysis in forage plants.

Location: Sevilleta LTER, New Mexico, USA (34 degree 21' N; 106 degree 53' W; 1650 m a.s.l.). Methods: We compared the distribution of subdominant plants in canopy, canopy edge and interspace microsites around individual shrubs (Larrea tridentata) and grasses (Bouteloua eriopoda) at a transition zone that has been encroached by shrubs within the past 50 - 100 a. Plots of variable size according to microsite type and dominant plant size were sampled. Results: Subdominant abundance was higher in microsites around L. tridentata shrubs than in microsites around B. eriopoda. Furthermore, differences in species abundance and composition were higher among microsites around grasses than among microsites around shrubs. The distribution of subdominants was mostly explained by their phenological characteristics, which indicates the importance of temporal variation in resources to their persistence. Conclusions: This study of coexistence patterns around dominants revealed ecological contrasts between two dominant life forms, but other factors (such as disturbances) have to be taken into consideration to evaluate landscape-scale diversity.

Survivorship curves were linear type II, with steeper rates of decline at higher temperatures. Longevity at 16 degree C (47.2 d) was significantly longer than that at 26 degree C (14.3 d) or 30 degree C (12 d). Adults under the 36 degree C survived only 4.9 d and laid no eggs. Percentage of eggs that hatched was relatively constant at approximately or about 40% at 16, 26, and 30 degree C. Numbers of egg clutches (ranging from 5.9 to 9.4), eggs per clutch (13.6-14.6), and eggs in the first clutch (9.0-15.1) did not differ significantly at these three temperatures. However, preoviposition period was significantly longer at 16 degree C (20.3 d) than at 26 degree C (6.3 d) and 30 degree C (4.9 d). Number of eggs laid was related to body weight by the equation E = -139.1 + 3.49w, where E is number of eggs laid per female lifetime, and w is the weight of the predator female. Life table analysis of P. maculiventris female adults showed that both net reproductive rate (R0) and gross reproductive rate (GRR) were highest at 26 degree C, estimated at 47.8 and 156.0 females per female, respectively. However, the shorter generation times at 30 degree C (T = 42.2 d) resulted in higher values for the intrinsic rate of increase (r = 0.09), the finite rate of increase ( lambda = 1.09), and doubling time (DT = 7.7 d). Analysis of cumulative egg production suggests that 26 degree C may be more suitable for maintaining colonies of P. maculiventris because of the sustained levels of egg production over a longer period, compared with the 30 degree C treatment.

No-choice tests showed that P. curvatus hovered over and attacked all three species of fire ants. The number of pupae successfully completing development to adult flies in the trials was 5.03 plus or minus 1.55 (mean plus or minus SE) per female fly in S. invicta, 0.66 plus or minus 0.24 per female fly in S. xyloni, and 0 per female fly in S. geminata. Paired preference tests showed that P. curvatus preferred to hover over S. invicta instead of S. xyloni 77 plus or minus 3% (mean plus or minus SE) of the time and preferred S. invicta over S. geminata 87 plus or minus 4% of the time. The oviposition attempts of active female P. curvatus were 2.8 times higher on S. invicta than on S. xyloni and 16 times higher on S. invicta than on S. geminata. These results demonstrate that this new biotype of P. curvatus is more host specific to North American red imported fire ants than a previous biotype collected from black imported fire ants.

Both species and sexes initiated flights throughout the day, and flight mill assays recorded flights throughout the night. For both species and flight systems, most flights were 5 min) that were of longer cumulative duration compared with L. hesperus. The longest flights were obtained with flight mills and were 17-18 times longer than the longest flight (22 min) in the flight chamber. Determination of flight periodicity, throughout the day and night, was only possible for tethered insects, and females exhibited more distinct periodicities for sustained flights than males. For L. hesperus females, sustained flights followed a diurnal to crepuscular periodicity, whereas sustained flights by L. lineolaris females were nocturnal. No significant correlations were found between egg load and any of the flight parameters when grouped by species, but there was a positive correlation between the number of spermatophores and several of the flight parameters for female L. hesperus. In the vertical flight chamber, takeoffs began at low light levels and were always higher for L. lineolaris than L. hesperus. Rates of climb toward the skylight cue were approximately 50 cm/s, indicating a capacity for strong, self-directed flight by both species.

More western flower thrips were attracted to blue (458-nm peak reflectance) sticky card traps compared with yellow (560 nm) or white sticky card traps. Blue light-emitting diodes (LEDs; 465-nm peak emission) increased the efficacy of blue sticky card traps for catching western flower thrips. Numbers of western flower thrips caught on blue flat rectangular card traps were increased 2.0-2.5 times when cards were equipped with blue LEDs. Hoverflies adults are pollinators, and larvae are natural enemies of aphids and other pest insects. Hoverfly adults were attracted to blue sticky card traps. Nylon screen cages effectively excluded the hoverflies from the blue sticky card traps.

The extracellular endoglucanase (EG) was purified to homogeneity from the culture supernatant by ethanol precipitation (75%, v/v), CM Bio-Gel A column chromatography, and Bio-Gel A-0.5 m gel filtration. The purified EG (specific activity 43.33 U/mg protein) was a monomeric protein with a molecular weight of 27 000. The optimum temperature and pH for the action of the enzyme were at 55 degree C and 4.0-6.0, respectively. The purified enzyme was fully stable at pH 4.0- 7.0 and temperature up to 60 degree C. It hydrolysed carboxymethyl cellulose and insoluble cellulose substrates (Avicel, Solka-floc, and Sigmacell 50) to soluble cellodextrins. No glucose, cellobiose, and short chain cellooligosaccarides were formed from these substrates. The purified EG could not degrade oat spelt xylan and larch wood xylan. It bound to Avicell, Solka-floc, and Sigmacell 50 at pH 5.0 and the bound enzyme was released by changing the pH to 8.0. The enzyme activity was enhanced by 27+/-5 and 44+/-14% by the addition of 5 mM MgCl sub(2) and 0.5 mM CoCl sub(2), respectively, to the reaction mixture. Comparative properties of this enzyme with other fungal EGs are presented.

An oligonucleotide probe that becomes fluorescent upon hybridization to the target DNA (Molecular Beacon, MB) was used in a real-time polymerase chain reaction (PCR) assay. As few as 4 to 7 colony-forming units (CFU) of L. monocytogenes per 25 g of artificially contaminated produce could be detected. A comparison of 2 commercially available kits using MC-PCR (iQ-Check, Bio-Rad Laboratories) and conventional PCR (BAX, Dupont Qualicon) was performed on artificially inoculated produce. The time required to detect L. monocytogenes (from produce to PCR) was considerably shorter for the iQ-Check protocol (approximately 26 h) compared with the BAX-PCR (approximately 52 h). The iQ-Check protocol was also used to confirm the identity of the L. monocytogenes isolates obtained during a microbiological screen of conventional and organic leaf lettuce and alfalfa sprout samples from local supermarkets. The iQ check protocol was successful in differentiating L. monocytogenes isolates from other Listeria spp. such as L. welshimeri, L. innocua, and L. ivanovii. This is the 1st report of the application of the MB probe being used for real-time detection of L. monocytogenes in whole and fresh-cut produce.

Smith)] requires knowledge of its preferred habitats throughout the year and a detailed description of seasonal changes in population numbers. 2. Molecular markers were used to determine the host strain (corn or rice) of male moths captured in sex pheromone-baited traps placed in different habitats in the overwintering areas of southern Florida. 3. The results indicated that rice strain moths were found in all traps and that this strain was the primary population observed in naturalised pasture and wetlands in southern Florida. In comparison, larger populations of both strains and a higher proportion of corn strain moths were observed in areas associated with golf courses, agriculture, or urban development. Corn strain adults were most prevalent during the spring and early summer. 4. These results represent the first geographical survey of fall armyworm host strain distribution in Florida and indicate that corn strain moths are limited in their habitat choice while rice strain moths have a substantially broader range. The localisation of the corn strain population to discrete areas at specific times of the year provides an opportunity to reduce or delay its northward migration.

To determine whether a gonadotropin-releasing hormone (GnRH) vaccine was effective in reducing pregnancy in bison and to study the safety of injecting GnRH in pregnant bison, a study was conducted at the Idaho Fish and Game Wildlife Health Laboratory in Caldwell, Idaho (USA). Four pregnant and two nonpregnant female bison were given a single injection of GnRH vaccine, and five pregnant adult females were given a sham injection that contained only adjuvant. Three of the GnRH-vaccinated bison that were pregnant at the time of vaccination delivered healthy calves. One treated bison had dystocia that resulted in a dead calf. All control bison delivered healthy calves. After calving, females of both groups were exposed to two bulls. Treated bison were palpated 6 wk after exposure to the bulls, and blood was drawn for pregnancy-specific protein B analysis. The six treated bison were not pregnant. The sham-treated bison became pregnant and delivered viable calves. This study demonstrates that a single dose of GnRH vaccine is effective in preventing pregnancy in female bison for at least 1 yr.

This technique involved extraction of predominantly cellular DNA from tilapia intestinal tracts and used a polymerase chain reaction assay to detect presence of type C sub(1) toxin gene. We consistently detected C. botulinum type C cells in tilapia gastrointestinal contents at a level of 7.5x10 super(4) cells per 0.25 g material or 1.9x10 super(3) cells. This technique is useful for determining prevalence of the potentially active organisms within a given population of fish and may be adapted to other types of C. botulinum and vertebrate populations as well.

Alternative control options are needed for a variety of reasons, including environmental impact and worker and food safety concerns. Microbial control agents such as the codling moth granulovirus (CpGV) offer alternatives to conventional insecticides for the control of codling moth. Six weekly applications of the label rate (1 L/ha) of the Carpovirusine registered formulation of CpGV in an experimental orchard naturally infested with codling moth provided control of first generation codling moth that was comparable to that of larvicidal oil and azinphos-methyl. Although the number of codling moth entries in fruit that were treated with virus alone was similar to that of control trees, the number of deep entries and the number of living codling moth larvae were significantly reduced on CpGV treated fruit. Despite blemishing, virustreated fruit with minute entries were suitable for consumption or for processing. Studies on the residual activity of Carpovirusine revealed a steady decline in virus activity 1 to 3 d following application. The use of two adjuvants, Nu-Film-17 registered and Raynox registered , did not protect virus from solar inactivation. Among the biological control options available for codling moth, CpGV provides effective and selective control of neonate larvae. Its use in lieu of broad spectrum insecticides will contribute significantly to the conservation of other natural enemies in the orchard agroecosystem.

Its seeds are dormant at dispersal and lose dormancy in response to moist chilling. Seeds from warmer low-elevation habitats have shorter chilling requirements and a higher optimum chilling temperature than those from colder habitats where winter snow regularly occurs. This ecotypic variation functions to time germination optimally in habitats with contrasting chilling regimes. Regulation of germination phenology is an important feature of the life history of this ecotonal species, which must be able to migrate elevationally through recruitment from seed in response to long-term climatic shifts in order to survive.

The Simultaneous Heat and Water (SHAW) model was applied to three soil types (loamy sand, sandy loam, and silt loam) to simulate near-surface soil temperature and water for predicting potential seed germination in post-wildfire revegetation. Three parameterization methods including initial parameter estimates, calibrated parameters, and measured moisture-release curve parameters were compared to assess the effect of parameter uncertainty on germination prediction. Initial parameters for the sandy loam soil resulted in an underprediction of germination times by 4.7 days for cheatgrass to 12.8 days for bluebunch wheatgrass compared to germination estimated from measured soil temperature and water conditions. Initial parameters resulted in predicted germination within 2 days of estimates for the other two soils. Model calibration to optimize the surface 20-cm water-content did not necessarily improve predicted germination. Model simulations using measured moisture-release curves resulted in germination prediction within a few days relative to estimates for all sites. Results suggest that the model can be used for long-term simulations of seedbed microclimate necessary to evaluate potential germination response of revegetation species and their weedy competitors.

We sampled 17 962 fish representing 52 species and compared assemblages within and among streams. Although annual and seasonal variability in assemblage structure was high, fish assemblages maintained characteristics unique to each stream. High variability in fish catch-per-unit-effort (CPUE) was exemplified in one site where total CPUE increased an order of magnitude from July 1993 to 1994. Species turnover and percent dissimilarity were often higher seasonally than annually, consistent with a period of change in spring to early summer and a return to similar species compositions between summers. Temporal variability was also high at the individual species level, and no species were classified as 'stable'. We found little evidence for correlation between changes in fish assemblage structure and measured habitat conditions. The fish characteristics fit the profile of 'colonizing assemblages', which probably resulted from both natural and anthropogenic causes. Flashy hydrographs , created in part by stream channelization and incision and watershed deforestation, may play a large role in structuring these fish assemblages. Extreme interannual variability in assemblages in the absence of detectable habitat change has important implications for the statistical power of fish monitoring programs designed to detect trends in fish assemblages over time.

Whole cantaloupe and fresh-cut pieces were inoculated with a five-strain cocktail of Salmonella to give 4.76 +/-0.23 log CFU/cm super(2) and 3.42 +/-0.13 log CFU/g, respectively. Inoculated whole melons and fresh-cut pieces were stored at 5 degree C for 7 days. Washing treatments were applied to inoculated whole melons at days 0, 3, and 7 of storage, and surviving bacterial populations were determined. The effect of the washing treatments on transfer of Salmonella to fresh-cut pieces prepared immediately after treatment was also determined. Directly inoculated fresh-cut pieces were treated at day 0, and surviving bacteria were enumerated at days 0, 3, and 7 of storage. The combination treatments of nisin-EDTA, nisin-NaL, nisin-KS, NaL-KS, and nisin- NaL-KS all resulted in reductions of approximately 3 log CFU/cm super(2) at day 0 for whole melons. When tested alone, all compounds, along with water washes, were ineffective. After 3 and 7 days of storage, the five combination washing treatments were less effective, resulting in reductions of approximately 2 log CFU/cm super(2). None of the combination treatments completely eliminated transfer of pathogen survivors to fresh-cut pieces. The combination treatments nisin-NaL, nisin-KS, NaL-KS, and nisin-NaL-KS, but not nisin-EDTA, gave significant (P < 0.05) reductions of Salmonella directly inoculated onto fresh-cut pieces. Washing with nisin-NaL-KS was significantly (P < 0.05) more effective than the other three combination treatments, resulting in a reduction of 1.4 CFU/g. Inhibition by the four effective treatments carried over from day 0 through day 7 of storage, with no increase in the population of Salmonella on the stored fresh-cut pieces. Sensory evaluations indicated that treatment of fresh-cut pieces with nisin-NaL and NaL-KS, but not nisin-KS or nisin-NaL-KS, were acceptable in terms of appearance, odor, and overall acceptability. After the required regulatory approval, treatment of whole cantaloupe with nisin in combination with EDTA, NaL, KS, or NaL and KS and of fresh-cut pieces with nisin-NaL or NaL-KS could help ensure the microbiological safety of fresh-cut cantaloupe.

Following four months storage at 0 degree C, the apples were left at room temperature for two weeks. Populations of antagonists were stable throughout the experiment and were higher on the heated than the non-heated fruit. Both antagonists reduced decay caused by P. expansum, whereas heat or heat in combination with either antagonist eliminated decay. Either heat or the antagonists alone reduced decay caused by C. acutatum, but a combination of the two was required to completely eliminate decay caused by this pathogen. Adding sodium bicarbonate to the heated or antagonist-treated fruit had little effect on decay caused by either pathogen but when used on non-heated fruit, it significantly reduced decay severity caused by P. expansum after four months at 0 degree C. The goal of this research is to combine alternative methods of control to provide an effective substitute for synthetic pesticides.

Because differences in storage temperature, length of storage, and the presence of storage pathogens may have contributed to the discrepant results from earlier studies, the impact of these three factors on sugarbeet root postharvest sucrose catabolism was determined. Sucrolytic activities and soluble carbohydrate concentrations were measured in roots exhibiting no pathological symptoms during storage at 6, 12, and 21 degree C and in roots exhibiting severe rotting symptoms due to infection by Penicillium spp. and Botrytis cinerea during storage at 6 degree C. Sucrose synthase was the predominant sucrolytic activity throughout storage, regardless of storage temperature, length of storage, or pathogenesis, and accounted for more than 90% of the total soluble sucrolytic activity present in roots. In disease-free roots, no significant change in sucrose synthase activity, soluble acid invertase activity, or insoluble acid invertase activity occurred in roots stored at 6 or 12 degree C, although an increase in sucrose synthase activity was observed in roots stored at 21 degree C. Alkaline invertase activity was impacted by the length of storage and exhibited a transient decline in activity at all storage temperatures. Glucose and fructose concentrations generally increased as a function of time in storage at 6, 12, and 21 degree C. In roots with severe rot, insoluble acid invertase activity declined, sucrose synthase and alkaline invertase activities were unchanged, and soluble acid invertase increased seven-fold. The increase in soluble acid invertase activity was primarily due to the presence of fungal acid invertase isoforms. These results indicate that sugarbeet sucrolytic activities change little during storage, regardless of storage temperature, length of storage, and pathogenesis, and suggest that sucrose synthase, as the predominant sucrolytic activity in stored roots, is central to postharvest sucrose catabolism in sugarbeet roots.

Single uredinial isolates (785 in total) were derived from the wheat leaf rust collections and tested for virulence phenotype on lines of Thatcher wheat that are near-isogenic for leaf rust resistance genes Lr1, Lr2a, Lr2c, Lr3, Lr9, Lr16, Lr24, Lr26, Lr3ka, Lr11, Lr17, Lr30, LrB, Lr10, Lr14a, and Lr18. In the United States in 2002, 52 virulence phenotypes of P. triticina were found. Virulence phenotype MBDS, which is virulent to resistance gene Lr17, was the most common phenotype in the United States. MBDS was found in the Southeast, Great Plains, and the Ohio Valley regions, and also in California. Phenotype MCDS, virulent to Lr17 and Lr26, was the second most common phenotype and occurred in the same regions as MBDS. Virulence phenotype THBJ, which is virulent to Lr16 and Lr26, was the third most common phenotype, and was found in the southern and northern central Great Plains region. Phenotype TLGJ, with virulence to Lr2a, Lr9, and Lr11, was the fourth most common phenotype and was found primarily in the Southeast and Ohio Valley regions. The Southeast and Ohio Valley regions differed from the Great Plains regions for predominant virulence phenotypes, which indicate that populations of P. triticina in those areas are not closely connected. The northern and southern areas of the Great Plains were similar for frequencies of predominant phenotypes, indicating a strong south to north migration of urediniospores.

In young apple orchards, there are conflicting requirements to control fire blight and allow sufficient tree growth for tree establishment. Application of prohexadione-calcium to various cultivars of orchard-grown apple trees ranging in age from newly planted to fifth-leaf trees indicated that fewer high-dose (125 or 250 mg times liter super(-1)) applications of prohexadione-calcium provided a better balance between fire blight control and growth in young orchards than multiple low-dose (30 or 63 mg times liter super(-1)) applications. The response of early-season shoot growth to prohexadione-calcium treatment dose was linear. However, trees that received high doses of prohexadione-calcium tended to grow more in the latter part of the season, resulting in little or no difference in total seasonal growth between trees that received a few high or multiple low doses of prohexadione-calcium. Enhancement of fire blight resistance by prohexadione-calcium was correlated with shoot growth suppression at the time of inoculation, and the resistance response to prohexadione-calcium treatment dose was linear. Fire blight management strategies that use prohexadione-calcium in young apple orchards are discussed.

The objective of this study was to characterize seedling and adult plant leaf rust resistance in hard red spring wheat cultivars grown in Minnesota, North Dakota, and South Dakota, and postulate the identity of the seedling leaf rust resistance genes in the cultivars. Twenty-six cultivars, near-isogenic lines of Thatcher wheat that differ for single leaf rust resistance genes, and three wheat cultivars with known leaf rust resistance genes, were tested with 11 different isolates of leaf rust collected from the United States and Canada. The leaf rust infection types produced on seedling plants of the cultivars in greenhouse tests were compared with the infection types produced by the same isolates on the Thatcher near-isogenic lines to postulate which seedling leaf rust resistance genes were present. Seedling leaf rust resistance genes Lr1, Lr2a, Lr10, Lr16, Lr21, and Lr24 were postulated to be present in spring wheat cultivars. Seedling genes Lr3, Lr14a, and Lr23 likely were present in some cultivars but could not be clearly identified in this study. Most of the cultivars had some level of adult plant leaf rust resistance, most likely due to Lr34. Cultivars that had seedling resistance genes Lr1, Lr2a, Lr10, or Lr16 had poor to intermediate levels of leaf rust resistance in field plots. Cultivars with combinations of seedling resistance genes Lr16 and Lr24 with additional adult plant resistance were highly resistant to leaf rust.

(common crupina, family Asteraceae), an introduced invasive weed in the northwestern United States, is a target of biological control efforts. During the spring of 2002, approximately 30 wilting C. vulgaris plants were found along a road from Volos to Portaria, Greece (39 degree 22'58''N, 22 degree 59'27''E, elevation 446 m). Wilting plants had irregular, purple, necrotic lesions extending along the main stems and petioles. In the laboratory, diseased leaves were surface disinfested and placed on moist filter paper in petri dishes. Acervuli with setae typical of a Colletotrichum sp. were observed after 2 to 5 days. A fungal isolate, DB 02-030, was isolated from these diseased leaves. Stems and leaves of 12-and 16-week-old plants (12 plants of each age) were spray inoculated with an aqueous suspension of 2 times 10 super(6) conidia per ml from 14-day-old cultures of DB 02-030 grown on acidified potato dextrose agar (APDA). Inoculated plants were placed in a dew chamber at 18 to 21 degree C with continuous dew and 8 h of light per day for 48 h. Plants were moved to a greenhouse bench with 8 h of light per day and watered twice daily. Symptoms developed after 7 days on 16-week-old plants (33% symptomatic) and 14 days on 12-week-old plants (17% symptomatic). No symptoms developed on control plants. By 61 days after inoculation, 67% of plants inoculated at 16 weeks of age were dead and 50% of plants inoculated at 12 weeks of age were wilted. Koch's postulates were repeated with isolates from two other plants. Isolate DB 02-030 was reisolated three times from 10 of 10 symptomatic leaves, 4 of 4 stems with necrotic lesions, and 4 of 4 stems with leaves from wilted inoculated plants. Conidia germination on water agar was 95% at 18 to 21 degree C with light compared with 19% in darkness or at 23 to 26 degree C. C. vulgaris is an annual plant that emerges during early spring and reproduces only by seeds. As a cool-temperature aggressive pathogen, isolate DB 02-030 has the potential as a biological control agent to reduce seed production and stands of C. vulgaris. This isolate fits the morphology of Colletotrichum gloeosporioides according to Sutton (2). On APDA, conidia were formed after 4 days. Conidia were hyaline, straight, cylindrical, nonseptate, and 18 to 27 times 3 to 6 mu m. Setae produced in acervuli were abundant, straight, narrow, and 75 to 210 mu m long times 3 mu m at the base. Appressoria in vitro were subglobose to clavate and 8 to 12 mu m in diameter. Nucleotide sequences were obtained for the internal transcribed spacer (GenBank Accession No. AY539806) and 28S (GenBank Accession No. AY539807) rDNA genes of this isolate. Parsimony analyses (unpublished), with sequences from GenBank and 25 isolates from established culture collections, indicate the isolate on C. vulgaris belongs to a clade of taxonomically problematic Colletotrichum spp. that are only distantly related to other isolates of C. gloeosporioides. A culture of DB 02-030 has been deposited at the Centraalbureau voor Schimmelcultures as CBS 114801.

Oleic acid albumin formulations that inhibit HNE may be applicable to treatment modalities for chronic wounds. Oleic acid/albumin formulations with mole ratios of 100:1, 50:1, and 25:1 (oleic acid to albumin) were prepared and found to have dose response inhibition properties against HNE. The IC sub(50) values for inhibition of HNE with oleic acid/albumin formulations were 0.029-0.049 mu M. Oleic acid/albumin (BSA) formulations were bound to positively and negatively charged cotton wound dressings and assessed for elastase inhibition using a fiber bound formulation in an assay designed to mimic HNE inhibition in the wound. Cotton derivatized with both carboxylate and amine functional groups were combined with oleic acid/albumin formulations at a maximum loading of 0.030 mg oleic acid + 0.14 mg BSA/mg fiber. The IC sub(50) values for inhibition of HNE with oleic acid/albumin formulations bound to derivatized cotton were 0.26-0.42 mu M. Release of the oleic acid/albumin formulation from the fiber was measured by measuring oleic acid levels with quantitative GC analysis. Approximately, 35-50% of the fiber bound formulation was released into solution within the first 15 min of incubation. Albumin was found to enhance the rate of elastase hydrolysis of the substrate within a concentration range of 0.3-50 g/L. The acceleration of HNE substrate hydrolysis by albumin required increased concentration of inhibitor in the formulation to obtain complete inhibition of HNE. Oleic acid formulations prepared with albumin enable transport, solubility and promote dose response inhibition of HNE from derivatized cotton fibers under aqueous conditions mimicking the chronic wound.

Inhibition was concentration dependent, with a 50% effective dose of 30 mu g of diferuloylputrescine/p-coumaroylferuloylputrescine per milliliter of medium. Aflatoxin inhibition levels of up to 93% were achieved using this conjugated polyamine material. This diconjugated polyamine mixture did not display inhibitory effects on A. flavus growth (mycelial weight) at any of the concentrations tested. A survey of hand-dissected corn (Zea mays) kernel tissues, including endosperm, germ, pericarp, and wax, revealed that the highest concentrations of these conjugated polyamines were localized in the pericarp of the seed. Analysis of a number of corn accessions did not reveal a correlation between diferuloylputrescine/p-coumaroylferuloylputrescine concentration and resistance/susceptibility to A. flavus infection. The localization of these diconjugated polyamine components in the pericarp, which functions as a physical barrier and surrounds the internal food storage reserves, suggests a defensive role for these materials.

Disease incidence ranged from <1 to 65% among vineyards in 2001. Our efforts to trap or capture potential disease vectors have indicated that the GWSS is the most likely vector. Disease incidence doubled in most vineyards during the 2002 production season. Spatial patterns of symptomatic vines in 2001 and 2002, as determined by ordinary runs analysis, showed strong evidence for within- and across-row aggregation of infected vines. In most fields, they were no disease gradients observed relative to GWSS source (e.g., citrus). Within fields, however, disease incidence displayed strong spatial dependence and a high degree of anisotropy, indicating strongly aggregated patterns of disease with distinct directional orientation. The within-row (0 degree ) and across-row (90 degree ) orientations generally were the predominant directions of increased disease incidence, consistent with vine-to-vine spread of X. fastidiosa. We concluded that the distribution of PD in vineyards reflected the feeding pattern of vectors carrying X. fastidiosa. Based on these results, effective PD management is likely to be based on practices that reduce significant insect vector populations and remove infected vines as soon as identified and on the use of resistant cultivars.

Measured stand characteristics included canopy density (67% and 75%) and basal area (43.4 and 24.1 m2 ha-1) for the higher and lower elevations, respectively. Temperature, relative humidity, net radiation, wind speed, and mass of snow on suspended trees provided data to determine whether sublimation rates of intercepted snow are more rapid at higher elevations associated with increased wind speed. Measurements showed the unexpected result that wind speed during sublimation periods was lower at higher elevations, probably because of terrain sheltering. The analysis examined 21 storm-free periods ranging in duration from 9 to 53 h. Sublimation rates per unit mass of intercepted snow were significantly larger at the lower-elevation site associated with warmer temperatures, lower relative humidity, and greater wind speeds. Application of meteorological data to an ice sphere model indicated that predicted mean sublimation rates of an ice sphere index were 23% plus or minus 7% more rapid at the lower elevation due to weather factors alone. However, greater snowfall at higher elevations produced greater interception, resulting in substantially more snow being sublimated back to the atmosphere at the upper site. Over the study period, sublimation of snow intercepted by the test trees amounted to 20%-30% of total snowfall accumulated at the sites during the 21 storms selected for analysis.

These forecasts are for 29 unregulated rivers with diversity in geography and climate. Deterministic evaluations revealed strong correspondence between observations and forecasts issued 1 April. Forecasts issued earlier in the season were more uncertain yet remained skillful. The average change in forecast performance between January and April was primarily linked to the climatological seasonal cycle of precipitation: regions with climatologically wet winters and dry springs (e.g., California) showed much more forecast improvement between January and April than did regions with dry winters and wet springs (e.g., western Great Plains, Colorado Front Range). Other climatological factors played a secondary role; for example, mixed rain-snow basins in the Pacific Northwest did not show as significant an improvement in skill versus lead time as might otherwise be expected. Mixed trends in 1 April forecast skill were noted since the 1980s, with increased skill in California and Nevada, and a decline in skill in the Colorado River basin. Increased variability in streamflow was also noted across most of the western United States, although this did not appear to be the only factor responsible for trends in forecast skill.

Two of the species are restricted to riparian habitats (Brickellia laciniata and Chilopsis linearis), three are classified as semi-riparian (Fallugia paradoxa, Prosopis glandulosa, and Rhus microphylla) and one is considered to be non-riparian (Flourensia cernua). Differences in gas-exchange patterns and water relations emerged among these six species, yet differences among obligate, semi-riparian, and non-riparian classes of species were evident, but not universal. Chilopsis and Brickellia did not develop the low plant water potentials that characterized some semi-riparian (Rhus) and non-riparian species (Flourensia) during periods of drought. Rates of photosynthesis and transpiration were highest in Prosopis throughout the study, and were relatively constant in Chilopsis during and after drought. Whether water became available as channel flow or direct rainfall appeared to play a role in the physiology of these arroyo shrubs.

Improved understanding of the physiologic responses of sugarcane to these conditions could help develop strategies to sustain high yields. The purpose of this study was to evaluate the effects of periodic flooding followed by drainage to different depths on single-leaf net photosynthetic rate (Ps), transpiration (Ts), and stomatal conductance (SC) of sugarcane. In 2000 and 2001, two sugarcane genotypes were planted as split plots in 12 lysimeters filled with Pahokee muck soil. Responses of Ps, Ts, and SC to four water-table treatments were measured for four 21-d cycles each year. Three treatments consisted of 7-d flooding followed by 14-d drainage to depths of 16, 33, or 50 cm. The fourth treatment was a continuous 50-cm water table. Analyses of individual cycles and analyses repeated over cycles generally identified neutral or positive responses of Ps, Ts, or SC to flood. Drained water-table depth did not consistently affect Ps, Ts, or SC, but when differences occurred, 16 cm was often a favorable drainage depth. These neutral and sometimes positive responses to short-duration flood or long-duration high water tables support previous reports of acceptable and sometimes enhanced yields from sugarcane exposed to high water tables. Previous findings were supported that time of formation of stalk aerenchyma in sugarcane may be a key factor for sustaining high yields after exposure to flood.

A variety of rapid methods exist that show promise for the presumptive detection of this pathogen without the immediate need for incubating test samples for hours to days in microbial enrichment and culture media. In recent years, highly sensitive chemiluminescence has become a more affordable and portable detection method. Chemiluminescent detection has been coupled with the selectivity of antibodies, magnetic microparticle separation/isolation, and enzymatic signal amplification in order to develop a rapid method, termed enzyme-linked immunomagnetic chemiluminescence (ELIMCL). This work presents the application of ELIMCL to the detection of E. coli O157:H7 in pristine buffered saline with a detection limit of 7.6x10 super(3) for live cells in approx. 75 min assay time. The blocking agent casein and the surfactant Tween 20 were used to lower background luminescence and thus maximize signal-to-noise ratios. After 5.5 h of enrichment culture, ELIMCL was demonstrated to detect E. coli O157:H7 inoculated in ground beef at 10 CFU/g in a total assay time of about 7 h.

For species that respond ecophysiologically, the use of summer precipitation is generally assumed to affect long-term plant growth and thus alter competitive interactions that structure plant communities and determine potential responses to climate change. We assessed ecophysiological and growth responses to large short-term irrigation pulses over one to three growing seasons for several widespread Great Basin and northern Mojave Desert shrub species: Chrysothamnus nauseosus, Sarcobatus vermiculatus, Atriplex confertifolia, and A. parryi. We compared control and watered plants in nine case studies that encompassed adults of all four species, juveniles for three of the species, and two sites for two of the species. In every comparison, plants used summer water pulses to improve plant water status or increase rates of functioning as indicated by other ecophysiological characters. Species and life history stage responses of ecophysiological parameters (leaf N, delta super(15)N, delta super(13)C, gas exchange, sap flow) were consistent with several previous short-term studies. However, use of summer water pulses did not affect canopy growth in eight out of nine comparisons, despite the range of species, growth stages, and site conditions. Summer water pulses affected canopy growth only for C. nauseosus adults. The general lack of growth effects for these species might be due to close proximity of groundwater at these sites, co-limitation by nutrients, or inability to respond due to phenological canalization. An understanding of the connections between short-term ecophysiological responses and growth, for different habitats and species, is critical for determining the significance of summer precipitation for desert community dynamics.

The study examined the bioconversion of oleic acid to 7,10-dihydroxy-8(E)-octadecenoic acid (DOD) and ricinoleic acid to 7,10,12-trihydroxy-8(E)-octadecenoic acid (TOD). A new DOD-like compound from linoleic acid was observed. All strains except NRRL B-247 exhibited varying levels of DOD production. NRRL B-1000, NRRL B-18602 and NRRL B-23258 with yields up to 84% were among the best DOD producers. TOD production generally paralleled DOD production at a relatively lower yield of up to 15%. Strains NRRL B-1000 and NRRL B-23260 were the best TOD producers. A DOD-like product in low yields was obtained from linoleic acid. The fatty acid bioconversion capability was related neither to growth rate nor to variation in the greenish pigmentation of the strains. Production of significant quantities of DOD and TOD from oleic and ricinoleic acids, respectively, appeared to be a characteristic trait of P. aeruginosa strains. A number of highly effective strains for DOD production were identified.

Since few sources of resistance to PPV have been identified, transgene-based resistance offers a complementary approach to developing PPV-resistant stone fruit cultivars. C5, a transgenic clone of Prunus domestica L., containing the PPV coat protein (CP) gene, has been described as highly resistant to PPV in greenhouse tests, displaying characteristics typical of post-transcriptional gene silencing (PTGS). We show in this report that C5 trees exposed to natural aphid vectors in the field remained uninfected after 4 years while susceptible transgenic and untransformed trees developed severe symptoms within the first year. C5 trees inoculated by chip budding showed only very mild symptoms and PPV could be detected in these trees by IC-RT-PCR. The PPV-CP transgene in C5 was specifically hyper-methylated with no detectable expression. These results indicate both stability and efficiency of PTGS-based PPV resistance in plum under field conditions.

Sequence analysis of trichothecene genes indicates that nivalenol production is the ancestral trait; however, deoxynivalenol producers occur worldwide and predominate in North and South America and in Europe. Analysis of a large field population (>500 strains) from Nepal identified three groups that were both genetically distinct and polymorphic for trichothecene production: SCAR1 comprising 95% deoxynivalenol producers, SCAR2 comprising 94% nivalenol producers, and SCAR3/5 comprising 34% deoxynivalenol producers/63% nivalenol producers. The ability to cause wheat head blight differed between SCAR groups and trichothecene chemotypes: deoxynivalenol producers were more virulent than nivalenol producers across all three SCAR groups and within the SCAR3/5 genetic background. These data support the hypothesis that production of deoxynivalenol rather than nivalenol confers a selective advantage to this important wheat pathogen.

Both chronic and acute infections are of concern, due to the fact that bacteria compete with the ethanol-producing yeast for sugar substrates and micronutrients. Lactic acid levels often rise during bouts of contamination, suggesting that the most common contaminants are lactic acid bacteria. However, quantitative surveys of commercial corn-based fuel ethanol facilities are lacking. For this study, samples were collected from one wet mill and two dry grind fuel ethanol facilities over a 9 month period at strategic time points and locations along the production lines, and bacterial contaminants were isolated and identified. Contamination in the wet mill facility consistently reached 10 super(6) bacteria/ml. Titers from dry grind facilities were more variable but often reached 10 super(8)/ml. Antibiotics were not used in the wet mill operation. One dry grind facility added antibiotic to the yeast propagation tank only, while the second facility dosed the fermentation with antibiotic every 4 h. Neither dosing procedure appeared to reliably reduce overall contamination, although the second facility showed less diversity among contaminants. Lactobacillus species were the most abundant isolates from all three plants, averaging 51, 38, and 77% of total isolates from the wet mill and the first and second dry grind facilities, respectively. Although populations varied over time, individual facilities tended to exhibit characteristic bacterial profiles, suggesting the occurrence of persistent endemic infections.

One strategy to improve strawberry resistance to phytoplasmas involves transgenic expression of anti-microbial peptide genes in phloem. For targeted phloem-specific expression, we constructed a binary vector with an expression cassette bearing the beta -glucuronidase (GUS) reporter gene (uidA) under control of the Arabidopsis sucrose-H super(+) symporter gene (AtSUC2) promoter. Transgenic strawberry lines were generated with high efficiencies by a modified transformation protocol, which combines the adoption of a 3-day pre-selection period following transformation, and the addition of 10- mu M thidiazuron to the regeneration medium.

Current practice for riparian gully control involves blocking the gully with an earthen embankment and installing a pipe outlet. Measures involving native vegetation would be more attractive for habitat recovery and economic reasons. To test the hypothesis that switchgrass (Panicum virgatum L.) hedges planted at 0.5 m vertical intervals within a gully would control erosion, we established a series of hedges in several concentrated flow channels. Two of the channels were previously eroded trapezoidal channels cut into compacted fill in an outdoor laboratory. The other channels were located at the margin of floodplain fields adjacent to an incised stream channel (Little Topashaw Creek) in Chickasaw County, Mississippi. While vegetation was dormant following two growing seasons, we created artificial runoff events in our test gullies using synthetic trapezoidal-shaped hydrographs with peak discharge rates of approximately 0.03, 0.07, and 0.16 m super(3) s super(-1), flow rates similar to those observed during natural runoff events in gullies at Topashaw. During these tests, we monitored flow depth, velocity, turbidity, and soil pore water pressures. Flow depths were generally <0.3 m, and flow velocities varied spatially and exceeded 2.0 m s super(-1) at the steepest points in some tests. Erosion rates remained modest for the conditions tested, as long as slopes were less than 3 horizontal to 1 vertical (33%) and step height between hedges was less than 0.5 m. Stability modeling of soil steps reinforced with switchgrass roots showed that cohesive forces were 3 times greater than shearing forces for 0.5 m step heights, and that therefore mass failure was unlikely even with the surcharge weight of a 0.2 m depth of ponded water. For step heights greater than 1 m, however, mass failure was observed and predicted to be the dominant erosion mechanism.

Satellite-based soil moisture can be obtained from passive microwave, active microwave, and optical sensors, although the coarse spatial resolution of passive microwave and the inability to obtain vertically resolved information from optical sensors limit their usefulness for watershed-scale applications. Active microwave sensors such as synthetic aperture radar (SAR) currently represent the best approach for obtaining spatially distributed surface soil moisture at scales of 10-100 m for watersheds ranging from 1 000 to 25 000 km super(2). Although SAR provides surface soil moisture, the applications listed above require vertically resolved soil moisture profiles. To obtain distributed soil moisture profiles, a combined approach of calibration and data assimilation in soil vegetation atmosphere transfer (SVAT) models based on recent advances in soil physics is the most promising avenue of research. This review summarizes the state of the science using current satellite-based sensors to determine watershed-scale surface soil moisture distribution and the state of combining SVAT models with data assimilation and calibration approaches for the estimation of profile soil moisture. The basic conclusion of this review is that currently orbiting SAR sensors combined with available SVAT models could provide distributed profile soil moisture information with known accuracy at the watershed scale. The priority areas for future research should include image-based approaches for mapping surface roughness, determination of soil moisture in densely vegetated sites, active and passive microwave data fusion, and joint calibration and data assimilation approaches for a combined remote sensing - modeling system. For validation, a worldwide in situ soil moisture monitoring program should be implemented. Finally, to realize the full potential of satellite-based soil moisture estimation for watershed applications, it will be necessary to continue sensor development, improve image availability and timely delivery, and reduce image cost.

Desertification continues to be a major threat to Iceland's natural resources. Revegetation in Iceland can both reduce C in the atmosphere by fixing C in vegetation and soil, and also reduce C emission by preventing further ecosystem damage, vegetation degradation and subsequent soil erosion. The sequestration potential in Iceland lies in the available land area and in the soil properties. Iceland has vast areas where vegetation can be enhanced or restored (10 000-45 000 km super(2)), and the Andic nature of Icelandic soils tends to immobilize C. In the year 2001 the Soil Conservation Service worked on revegetation of roughly 13 000 ha or 130 km super(2), resulting in C sequestration of about 8000-14000 Mg C in 2001. Reclamation of degraded land through changed land use, and/or seeding and fertilizing can promote sustainable development and healthier ecosystems, increase biological diversity and soil fertility, in addition to mitigating climate change through C sequestration.

The objectives of this study were to evaluate isotherms for adsorption and desorption of chlorpyrifos on colloidal materials and to advance understanding of interaction mechanisms between chlorpyrifos and colloidal materials. Six Ca-saturated reference smectites, one Ca-saturated humic acid (Ca-humate), and one suspended sediment sample, collected from the Upper Cedar River, Iowa, were studied. A batch equilibration technique was employed to quantify adsorption and desorption isotherms for chlorpyrifos over the 0 to 100 mu g L super(-1) concentration range in a 0.01 M CaCl sub(2) background. Large differences in sorption affinity and variation in desorption hysteresis were found among the smectites. Neither chlorpyrifos adsorption nor its desorption were correlated with cation exchange capacity, surface area, or surface charge density of the smectites. The evidence suggests that physical interaction between chlorpyrifos and smectites is the dominant mechanism for adsorption of chlorpyrifos in aqueous systems. Chlorpyrifos was very strongly sorbed on Ca-humate and was not desorbed from the Ca-humate back into the aqueous solution. Chlorpyrifos was moderately sorbed on river sediment, and a large adsorption-desorption hysteresis was also found. The study implies that the nature of both organic and inorganic materials in suspended sediment can influence the adsorption-desorption behavior of chlorpyrifos in aqueous systems.

ER - TY - JOUR T1 - Cation and Water Content Effects on Dipole Rotation Activation Energy of Smectites AN - 17291859; 6086988 AB - In soil science, single frequency permittivity measurements are used to determine soil water content, and single frequency bulk electrical conductivity is used to determine soil salinity. The accuracy of these measurements may be influenced by complex interactions between frequency, temperature, and water that is tightly bound to clay surfaces. The purpose of this study is to determine the effect of temperature, saturating cation, water content, smectite properties, and frequency on electrical properties of humidified clays by analyzing three different activation energies for dipole rotations, which are calculated from the temperature dependence of electrical properties. Four reference smectites saturated with K, Na, Ca, and Mg and equilibrated at relative humidities ranging from 56 to 99% were investigated over a frequency range from 3 x 10 super(5) to 1 x 10 super(9) Hz. Two of the three activation energies were found to decrease slightly as water content increased. Higher activation energies were found for smectites saturated with Mg and K and lower values for smectites saturated with Na and Ca. Trends for type of clay were variable but appeared to be influenced by both the total water content and the distribution of water between the interlayers and the external surfaces of the smectite quasi-crystals. Changes in quasi-crystal orientation induced by thermal cycling were also found to influence the activation energies. The results indicate complex frequency and temperature dependent interactions impact electrical properties of the clays. We conclude that no simple equation will correct for temperature and clay content effects on single frequency measurements of permittivity or bulk electrical conductivity.

Voigt, patches throughout Kailua-Kona, Hawaii Island, HI, were identified as persistent sources of melon fly, Bactrocera cucurbitae (Coquillett). These patches had a low incidence of Psyttalia fletcheri (Silvestri), its major braconid parasitoid natural enemy in Hawaii, and were used to evaluate augmentative releases of P. fletcheri against melon fly. In field cage studies of releases, numbers of melon flies emerging from ivy gourd fruit placed inside treatment cages were reduced up to 21-fold, and numbers of parasitoids were increased 11-fold. In open field releases of P. fletcheri into ivy gourd patches, parasitization rates were increased 4.7 times in release plots compared with those in control plots. However, there was no significant reduction in emergence of melon flies from fruit. In subsequent cage tests with sterile melon flies and P. fletcheri, combinations of sterile flies and P. fletcheri produced the greatest reduction (9-fold) in melon fly emergence from zucchini, Cucurbita pepo L. Reductions obtained with sterile flies alone or in combination with parasitoids were significantly greater than those in the control, whereas those for parasitoids alone were not. Although these results suggest that the effects of sterile flies were greater than those for parasitoids, from a multitactic melon fly management strategy, sterile flies would complement the effects of P. fletcheri. Cost and sustainability of these nonchemical approaches will be examined further in an ongoing areawide pest management program for melon fly in Hawaii.

Continuous marsh constructed wetlands have been shown to be effective in treating swine lagoon effluent and reducing the land needed for terminal application. Constructed wetlands have also been used widely in polishing wastewater from municipal systems. Constructed wetland design for animal wastewater treatment has largely been based on that of municipal systems. The objective of this research was to determine if a marsh-pond-marsh wetland system could be described using existing design approaches used for constructed wetland design. The marsh-pond-marsh wetlands investigated in this study were constructed in 1995 at the North Carolina A&T University research farm near Greensboro, NC. There were six wetland systems (11 m x 40 m). The first 10-m was a marsh followed by a 20-m pond section followed by a 10-m marsh planted with bulrushes and cattails. The wetlands were effective in treating nitrogen with mean total nitrogen and ammonia-N concentration reductions of approximately 30%; however, they were not as effective in the treatment of phosphorus (8%). Outflow concentrations were reasonably correlated (r super(2) 0.86 and r super(2) 0.83, respectively) to inflow concentrations and hydraulic loading rates for both total N and ammonia- N. The calculated first-order plug-flow kinetics model rate constants (K sub(20)) for total N and ammonia-N (3.7-4.5 m/day and 4.2-4.5 m/day, respectively) were considerably lower than those reported in the limited literature and currently recommended for use in constructed wetland design for animal wastewater treatment.

In this study, the impact of decade-scale variations in annual and seasonal precipitation on streamflow and evapotranspiration (ET) were identified for 10 watersheds in Nebraska, Kansas, and Oklahoma. In the Great Plains, an upward trend in precipitation over the last two decades of the 20th Century had a strong impact on streamflow and a comparatively weaker impact on ET. Even though precipitation, streamflow, and ET amounts differed between watersheds, the trend due to the precipitation increase was similar for all watersheds. Increased precipitation led to a disproportionately large increase in streamflow and comparatively smaller increase in ET. On average, a 12% increase in annual precipitation led to a 64% increase in streamflow, but only a 5% increase in ET. The seasonal partitioning of the annual precipitation increase was, in most cases, biased toward the fall, winter, and spring, with little or no change during the hot summer months. The strong streamflow response indicated that planning and management of surface-water storage and supply can be critically impacted by decade-long trends in precipitation. The lack of significant increase in precipitation and streamflow during summer suggests that any existing shortages will likely remain despite the observed annual precipitation increase. The ET response suggests that dryland farming and ecosystem vitality could benefit from the increased precipitation in fall, winter, and spring, but the relative impacts are more modest compared to the streamflow response and do not occur during summer when potential ET is greatest. Finally, since the mid-1990s precipitation and streamflow in a number of Oklahoma watersheds have shown a gradual decline from peak values in the late 1980s toward more average conditions. This declining trend in streamflow may be important for planning and management of water resources systems that must meet an increasing demand for water by a growing society while at the same time considering environmental and recreational needs.
