Two separate trials were performed with six and five birds, respectively. ARISA community profiles identified a period of community transition at week 12 of age in both trials. A significant increase of Ca. coli was also detected at week 12 in one trial, suggesting a possible correlation between microbiota destabilization and pathogen prevalence. Libraries of ribosomal small subunit 16S genes representing weeks 9, 11, 12 and 14 of both trials were sequenced. Whereas fingerprint and sequence analyses indicated significant differences in the species composition between the two trials, in general sequence library and dot-blot analyses indicated that Clostridia-like species decreased in prevalence over time. While B. uniformis prevalence in the two trials rose from 7% and 0% of the library clones at week 9 to 84% and 79% at week 11, real-time PCR did not support these results, with only approximately twofold and sixfold increases in internal transcribed spacer copy numbers observed.

Standard restriction fragment length polymorphism (RFLP) of these sequences was compared with single-strand conformation polymorphism (SSCP). Diversity indexes showed that both 16S-SSCP and ISR-SSCP improved resolution (D >= 0.9) when compared with standard RFLP. ISR-SSCP offered a simpler banding pattern than 16S-SSCP while providing high discrimination between isolates. SSCP analysis of rRNA genes proved to be a simple, rapid, and cost-effective method for routine fingerprinting of F. columnare.

Piperine and piperlongumine, natural alkaloids of Piper longum, significantly inhibited OTA production at 0.001% (w/v) for all aspergilli examined. Piperine and piperlongumine affected the polyketide synthesis step of OTA production and inhibited production of citrinin. Curcumin, a constituent of tumeric, completely inhibited mycelial growth of A. alliaceus isolate 791 at 0.1% (w/v) and decreased OTA production by similar to 70% at 0.01% (w/v). Sesamin, a constituent of sesame oil, inhibited OTA and OTB production by 60 and 45%, respectively, at 0.1% (w/v), showing its effect was on chloroperoxidase and polyketide synthase activity. The potential advantage of these natural products to reduce ochratoxin contamination of agricultural commodities is discussed. C1 Nanotoxtech Co Ltd, Res Stn, Songnam 463709, South Korea.

The purpose of this study was to investigate the effects of dietary soy isoflavones on early stage colon cancer in various ages of female rats. Young (1 month), mature (11 month) and old (22 month) female Fisher 344 rats were fed either the control diet or a diet containing 0.4%, soy isoflavone isolate for 1 week, injected once with 20 mg/kg azoxymethane (AOM) and maintained on the diets for another 15 weeks. The concentration of isoflavones in the diet was 2 g/kg diet, composed of 1.2 g/kg genistin, 0.7 g/kg daidzin and 0.1 g/kg other isoflavones including glycitin, acetylgenistin, acetyldaidzin, genistein, daidzein, and glycitein. There was no difference over all ages in the development of preneoplastic colonic aberrant crypt foci between rats fed the soy compared to the control diet, indicating that the soy diet did not provide protection against early stage colonic carcinogenesis. On the contrary, several adverse effects of soy supplementation in female AOM-treated rats were observed. Soy-supplemented rats had greater weight loss and a slower recovery of body weight following the AOM injection compared to rats fed the control diet and these changes increased with age. Five of the 21 rats fed the soy supplement died before the end of the experiment while all animals on the control diet survived to term. The density of normal crypts lining the colonic mucosa was reduced in rats fed the soy compared to control diet, indicating gastrointestinal damage. Uterine weights, serum estradiol and serum isoflavone levels were increased in mature and old female rats fed the soy-supplemented diets compared to age-matched controls, suggesting an increasing estrogenic response with age to isoflavone supplementation. These adverse effects of soy isoflavones in aged female animals need further examination because women, and particularly older women, are the prime target population for consumption of soy supplements.

Strawberries stored at high oxygen atmospheres (>40 kPa) showed higher antioxidant capacity, total phenolics, less decay, and longer postharvest life than those stored in air. Fruit stored under high oxygen atmospheres generally emitted lower levels of volatile compounds than those stored in air. However, individual volatile compounds were affected differently. While the emission of most volatiles decreased under high oxygen atmospheres during storage, the production of some volatile compounds such as methyl acetate and methyl hexanoate increased. In conclusion, strawberries stored under superatmospheric oxygen conditions maintained higher levels of antioxidant capacity but retained lower levels of volatile production than those stored in air.

TI Effects of various fire-retardants on plate shear and five-point flexural shear properties of plywood SO FOREST PRODUCTS JOURNAL LA English DT Article ID BENDING TEST; STRENGTH; OSB AB The influence of four fire-retardant systems on the planar (rolling) shear properties of structural hardwood plywood is evaluated using two possible ASTM D2718 test methodologies: the plate-shear method and the five-point flexural shear method. Knowing the planar shear properties and the potential of the various fire-retardant systems to affect properties is critical in engineering design. The various fire-retardant systems were found to reduce plate shear properties for plywood more than flexural shear properties depending on the fire-retardant chemical and its chemical loading level. We also found the inherent variability of plate shear data was greater than it was for flexural shear data. We conclude that there exist practically important differences between the results derived in the two planar (rolling) shear test methods for fire-retardant treated plywood.

To summarize the main defect features and to build our defect knowledge base, we measured, photographed, and categorized hundreds of real log defect samples. Three-dimensional laser-scanned range data captured the external log shapes and showed bark pattern, defective knobs, and depressions. Severe defects were identified via the analysis of 3-D log data using decision rules derived from analysis of the knowledge base. Defects were detected by examining contour curves generated from radial distances determined by robust 2-D circle fitting to the log-data cross sections. There were a total of 68 severe defects, of which 63 were correctly identified. There were 10 nondefective regions falsely identified as defects.

Patawaran, Maria Aries TI Impact of curve sawing on southern pine dimension lumber manufacturing: Part 2 - Sawtimber requirements and supply SO FOREST PRODUCTS JOURNAL LA English DT Article AB This paper provides valuable insights into the potential impact of curve sawing on the sawtimber requirements and supply of southern pine dimension lumber mills. Specifically, the potential input log volume and delivered cost savings of large (i.e., with annual output of at least 50 million board feet (BF)) southern pine dimension lumber mills that shift from conventional sawing to curve sawing of cants were estimated. Such impact was assessed at the state or regional level by assuming that the existing 150 large southern pine dimension lumber mills in the South could have curve sawing installations similar to that of the mill in Alabama that cooperated in a 2003 case study. It was also assumed that these attain levels of conversion efficiency similar to that of the study mill in processing input logs with the same distribution in terms of size and severity of sweep or crookedness. The results of the study reveal that an average savings in southern pine sawtimber input of about 10.4 percent could be attributed to curve sawing. For a sawmill like the study mill, which was producing about 274,000 BF of lumber per 8-hour workshift, this means log input savings of about 3,830 ft(3) with an estimated delivered cost savings of about $7,046 (based on 2003 nominal prices) per 8-hour workshift, on average. At the regional level, the aggregate annual input log volume savings of the aforementioned 150 mills operating at capacity could be about 97 to 400 million ft(3) or about 205 million ft(3), on average. Based on 2003 nominal prices, the aggregate annual savings in delivered log cost could be from about $177 million to $732 million, or a weighted average of approximately $377 million. Such input log savings increase (or decrease) with the level of lumber production at the average rate of 14 ft3 (or $25.69 of delivered cost) per thousand B F of lumber Output. Even greater input log savings could be expected if larger proportions (volume-wise) of logs with at least 3-inch sweep were inputted.

Specifically, the incremental net revenues realizable from curve sawing by southern pine dimension mills and the maximum rational investment (MRI) for such a system were estimated, given the level of mill productive capacity or lumber production per unit time. Results from regression analysis indicate that the expected incremental net revenues from curve sawing increase (or decrease) with mill productive capacity or production level at an average rate of about $24.27 per thousand board feet (MBF) of lumber output, based on 2003 nominal prices. There is a reasonably good chance (about 68%) that such rate of increase (or decrease) would be between $22.12 and $27.51 per MBF of lumber output. In this connection, the expected MRI increases (or decreases) at the rate of about $78,930 to $98,700 per MBF of lumber output or a weighted average of $87,830 per MBF of lumber output, assuming a 10-year service life. These estimates would be even greater if a larger proportion of the input logs, i.e., more than the 16.4 percent used by the study mill, have a minimum sweep of 3 inches.

The last comprehensive study of Pennsylvania's roundwood processors was conducted in 1988 by Wharton and Bearer (1994), who found that firms utilized and/or disposed of 120 million cubic feet (mmft(3)) of residues produced from a total roundwood volume of 1.450 billion board feet (BBF). Data collected from a mail survey of all identified roundwood purchasers in Pennsylvania in 2003 (n = 334) indicated that roundwood purchase volume decreased slightly to 1.266 BBF with 94 mmft(3) Of accumulated residues that were utilized and/or disposed of as waste. Roundwood purchasers include any Pennsylvania firm that bought roundwood (sawlogs, veneer logs, and pulpwood) from Pennsylvania and adjoining states in 2003. This total volume of residues consisted of 20 percent bark, 45 percent coarse, and 35 percent fine residues in 2003. The specific end uses for these three residue types changed dramatically over the 15-year span (1988 to 2003) with overall residential fuel use declining and uses for pulp and fiber composites, industrial fuels, and agricultural/horti cultural products increasing. Pennsylvania's roundwood purchasers utilized 99 percent of their accumulated mill residues in 2003, a 6 percent increase from the overall percent utilized in 1988.

To date there are limited studies of hydrologic impacts resulting from contemporary timber harvest in this region. Streamflow data were collected since 1991 at the Mica Creek Experimental Watershed (MCEW) in northern Idaho. Treatments were designed to isolate the effects of road construction and two different harvest practices (50% clearcut, 50% partial cut). The change in water yield was assessed using linear regression and analysis of covariance (ANCOVA). Water yield increased in excess of 270 mm/yr (P < 0.01) after clearcut harvesting, and by more than 140 mm/yr (P < 0.01) after partial cut harvesting. Monthly and seasonal analyses revealed the largest impacts of harvest practices on water yield during the snow deposition and melt season from November through June. Dry season analyses (July through October) indicated negligible water yield increases after treatments. Estimates of evapotranspiration (ET) as the residual of the catchment water balance suggest that ET was reduced by 35% and 14% after clearcut and partial cut harvest, respectively. These results establish a base on which to develop tools for effective watershed management in the northern Idaho continental/maritime hydroclimatic region.

Continuous channel surveys (6.4 km) were conducted in third- through fifth-order streams (drainage area < 10 km(2) and slope < 7%) where debris fan effects al: confluences were most evident. This basin size contains the majority of channels (67%) in the central Coast Range with gradients that are used by coho salmon (Oncorhynchus kisutch Walbaum). The close spacing between headwater tributaries susceptible to debris flows (118 m average) resulted in long continuous sections of fish-bearing streams that were bordered by debris fans (103 m average) and debris fans impinging on 54% of the total channel length surveyed. Debris flows also supplied the majority of wood (58% of pieces) to the surveyed fish-bearing channels. The highest values of large wood, boulders, and channel gradients were associated with debris fans at confluences with headwater tributaries, while deeper sediment deposits were often associated with fans but also extended up and downstream from fans. The spacing and network pattern of debris flow-prone headwater tributaries influenced the spatial structure of channel morphology and aquatic habitats leading to a high degree of physical heterogeneity and patchiness in channel environments. Our study contributes to a growing emphasis on the role of tributary confluences in structuring channel morphology and aquatic habitats in mountain drainage basins and argues for including a confluence component to stream classification and habitat typing schemes.

Quantitative differences among headwater channels may offer an objective basis for prioritizing streamside protection. Here, we examine differences among headwater channels as potential transport corridors for debris flows. Specifically, we model differences among hill slopes and headwater channels in probabilities of initiating and being traversed by debris flows that deliver to fish-bearing channels. We develop an approach to rank these probabilities and apply the ranks in delineating alternative streamside management zones. Initiation and traversal probabilities are estimated from an empirically calibrated debris-flow model using regionally available 10-m digital elevation data. Alternatives are delineated by encompassing 25%, 50%, and 75% of debris-flow susceptible hill slopes and headwater channels. Highest initiation and traversal probabilities were contained in a relatively small percentage of the study area. Encompassing lower probabilities required disproportionately larger areas. Substituting delineated alternatives for currently prescribed headwater riparian management zones decreased the total area encompassed on federal lands but increased it on private and state lands. Our intent is not to advocate for any particular alternative but to demonstrate that knowledge about how headwater channels differ over large areas can help tailor riparian policies.

TI Riparian buffer and density management influences on microclimate of young headwater forests of western Oregon SO FOREST SCIENCE LA English DT Article DE riparian buffers; density management; edge effects; Douglas-fir ID AIR-TEMPERATURE GRADIENTS; DOUGLAS-FIR FORESTS; OLD-GROWTH FORESTS; PACIFIC-NORTHWEST; COAST RANGE; UNITED-STATES; SMALL STREAMS; CLEAR-CUT; EDGE; WASHINGTON AB Thinning of 30- to 70-year-old Douglas-fir (Pseudotsuga menziesii [Mirb.] Franco) stands is a common silvicultural activity on federal forest lands of the Pacific Northwest, United States. Empirical relationships among riparian functions, silvicultural treatments, and different riparian buffer widths are not well documented for small headwater streams. We investigated buffer width and density management effects on riparian microclimates of headwater streams in western Oregon. Spatial variations in stand density, canopy cover, and microclimate were measured along transects extending from stream center upslope into thinned stands, patch openings, or unthinned stands, with riparian buffers ranging from < 5 m up to 150 m width. For treated stands, summer mean daily air and soil temperature maxima increased, and mean daily humidity minima decreased with distance front stream. Microclimate gradients were strongest within 10 m of stream center, a distinct area of stream influence within broader riparian areas. Thinning resulted in subtle changes in microclimate as mean air temperature maxima were 1 to 4 degrees C higher than. in unthinned stands. With buffers 15 m or greater width, daily maximum air temperature above stream center was less than 1 degrees C greater, and daily minimum relative humidity was less than 5% lower than for unthinned stands. In contrast, air temperatures were significantly warmer within patch openings (+6 to +9 degrees C), and within buffers adjacent to patch openings (+3 degrees C) than within unthinned stands. Buffers of widths defined by the transition from riparian to upland vegetation or topographic slope breaks appear sufficient to mitigate the impacts of upslope thinning on the microclimate above headwater streams.

Andrews Experimental Forest, Oregon, from June, 2003 to June, 2004. Thirty to forty years after harvest, macroinvertebrate density and richness did not differ among streams through young growth and old growth. Effects of deciduous riparian vegetation, including seasonal canopy openings and litterfall, continue to influence patterns of macroinvertebrate responses to forest harvest, as shown by higher densities of shredders in young-growth sites, the timing of emergence within basin pairs, and assemblage differences in two of the pairs of basins. The paired-basin design helped in distinguishing the specific influences of forest age from natural variability of macroinvertebrate distributions within the 5th order Lookout Creek basin. Our study suggests that understanding how macroinvertebrates respond to historical disturbances is enhanced by measures sensitive to changes in life history, such as rates of emergence, and to functional composition that reflect resource availability.

Preexisting site: conditions, including down wood, and forest management measures, such as riparian buffers, may moderate these effects, but these relationships are poorly understood. To explore whether down wood and riparian buffer widths might influence short-term responses to thinning, we sampled salamanders using ground searches before and during the first 2 years after experimental thinning at two 45- to 65-year-old headwater forest sites in western Oregon that differed in down wood volume. Prethinning distributions of terrestrial salamanders overlapped one- and two-tree height riparian buffers, and except for red-backed salamanders, overlapped very little with narrower streamside or variable-width buffers. At the site where down wood volume was low, captures of ensatina (Ensatina eschscholtzii Gray) and western red-backed salamanders (Plethodon vehiculum Cooper) both declined by 40% in thinned areas. In contrast, captures of ensatina and Oregon slender salamanders (Batrachoseps wrighti Bishop) were not significantly affected by thinning at the site where down wood volume was high. Our results suggest that site conditions, such as down wood volume, and riparian buffers may influence the effect of thinning on terrestrial salamanders, and demonstrate the tight linkage among management of aquatic, riparian, and upslope resources in headwater forests.

Pre and posttreatment surveys were carried out on 68 headwater stream reaches (including 23 unthinned reference reaches) at 11 sites in western Oregon. Streams were in managed conifer stands, 40 to 80 years old, where the thinning treatment reduced stands from 600 trees per hectare (tph) to 200 tph. Treatments consisted of four widths of riparian buffers approximately 6, 15, 70, and 145 m on each side of streams. Over three study years, 3,131 individuals of 13 species were detected. For the more common instream and bank species analyzed, capture rates persisted posttreatment with no negative treatment effect from thinning with any of the buffer widths. More animals were detected after thinning in treatment reaches compared to reference reaches for rough-skinned newts (Taricha granulosa Skilton) occurring on stream banks, and for instream coastal giant salamanders (Dicamptodon tenebrosus Baird and Girard). Treatment effects on instream habitat parameters were not detected. Interannual variation was evident for western red-backed salamanders (Plethodon vehiculum Cooper), and several habitat conditions including pool-riffle ratio, stream spatial intermittency, stream width, and down wood. Overall, riparian buffers with moderate upslope thinning (200 tph) seemed to have retained the aquatic vertebrate community along channels among sites in the first 2 years posttreatment; however, several limitations of the study reduce the inference of the findings, and these preliminary results are best interpreted as hypotheses for further investigation.

Headwater stream types in our sample included perennial, spatially intermittent, and dry reaches. We captured 454 fish of three species groups and 1,796 amphibians of 12 species. Using canonical correlation, nonmetric multidimensional scaling ordination, and generalized linear models, we identified species and assemblages associated with reach hydrologic type (e.g., perennial, intermittent, dry), stream size, gradient, and substrate composition. Our findings of torrent salamander (Rhyacotriton species) occurrences in spatially intermittent streams, and patchy and infrequent occurrences of Cottus fish (sculpins) and coastal tailed frogs (Ascaphus truei Stejneger) suggests these taxa warrant consideration during headwater management for retention of locally distinct biotic resources.

These streams rapidly descend from gradients greater than 20% to less than 5% in U-shaped glacial valleys. We use a set of studies on headwater streams in southeast Alaska to define headwater stream catchments, link physical and biological processes, and describe their significance within watersheds. We separate headwater stream systems into four units that have distinct hydrologic and geomorphic processes that link terrestrial processes to aquatic systems. Headwater streams collect, process, and transport material downstream. Physical and biological processes in headwater streams are complex and closely tied to terrestrial processes. Steps and step pools formed by large wood are keystone structures that link physical processes to biological processes and increase channel complexity. Large and coarse wood debris dams form in-channel step structures and act as valves that regulate the downstream flow of material. A large amount of inorganic and organic sediment is stored in step structures, which may be biological hotspots in headwater streams. Step pools formed by large woody debris are critical habitat for Dolly Varden (Salvelinus malma), juvenile coho salmon (Oncorhynchus kisutch), steelhead (O. mykiss), and cutthroat trout (O. clarkii) in reaches with gradients from less than 4% to those greater than 10%. Landslides and debris flows are the dominant channel-altering processes in headwater streams and remove the step profile. Management activities that increase the number and frequency of channel disturbance events in headwater streams can have important and long-term consequences throughout a watershed.

Extensive analysis of 10,397 ESTs, derived from thirteen cDNA libraries of F. grami-nearum grown under diverse conditions, identified a novel cluster of eight genes (gene loci fg08077-fg08084) located within a 17 kb region of genomic sequence contig 1.324. The expression of these genes is concomitantly up-regulated under growth conditions that promote mycotoxin production. Gene disruption and add-back experiments followed by metabolite analysis of the transformants indicated that one of the genes, fg08079, is involved in butenolide synthesis. The mycotoxin butenolide is produced by several Fusarium species and has been suggested, but not proven, to be associated with tall fescue toxicoses in grazing cattle. This is the first report of the identification of a gene involved in the biosynthetic pathway of butenolide. Crown copyright (c) 2006 Published by Elsevier Inc. All rights reserved.

We present a modified Transposon Display molecular marker system allowing amplification of genomic regions containing DcMaster elements. We scored 77 DcMaster Transposon Display (DcMTD) amplicons, of which 54 (70%) were segregating in the F(2) progeny from the cross between wild and cultivated carrot. Segregating amplicons were incorporated into a previously developed molecular linkage map of carrot. Twenty-eight markers were attributed to the wild parent, 23 originated from the cultivated parent, and three markers remained unlinked. The markers were evenly distributed among the nine linkage groups. However, differences in the distribution pattern of DcMaster insertion sites in the genomes of the wild and cultivated parent were observed. Specificity of the obtained amplicons was confirmed by sequencing and three putative DcMaster subfamilies, differing in the sequence of their terminal inverted repeats, were revealed.

The IGFs-induced GVBD but not OMC in striped bass follicles in vitro, but OMC and not GVBD in white bass follicles. Striped bass are group-synchronous single-clutch spawners whereas white bass and white perch are group-synchronous multiple-clutch spawners. In the present study, we found that IGFs-induced ONIC in white perch. Although IGF-I weakly stimulated GVBD in follicles from some late stage fish, it is likely that IGF-I did not directly induce GVBD but instead induced OMC, enabling endogenous MIH to act. Bovine insulin was less potent than IGFs at inducing OMC, suggesting that the IGFs were acting through an IGF-I receptor. IGF-I increased testosterone and estradiol-17 beta production by ovarian fragments but decreased production of 17,20 beta-dihydroxy-4-pregnen-3-one, a precursor to the MIH, which was below detection levels. As with the other Morone species, phosphatidylinositiol 3-kinase inhibitors, wortmannin and LY 294002, and the translation inhibitor cyclohexamide, attenuated GVBD induced by human chorionic gonadotropin (hCG), 20 beta-S, and a combination of IGF-I and 20 beta-S. Only hCG-induced GVBD was attenuated by the transcription inhibitor actinomycin D. The IGFs have shared and disparate actions on ovarian follicle maturation among Morone species that appear to be linked to reproductive strategy and exhibit similarities in mechanisms of action.

To determine the optimal strategies for implementing association analysis in soybean (Glycine max L. Merr.), we analyzed the structure of LD in three regions of the genome varying in length from 336 to 574 kb. This analysis was conducted in four distinct groups of soybean germplasm: 26 accessions of the wild ancestor of soybean (Glycine soja Seib. et Zucc.); 52 Asian G. max Landraces, the immediate results of domestication from G. soja; 17 Asian Landrace introductions that became the ancestors of North American (N. Am.) cultivars, and 25 Elite Cultivars from N. Am. In G. soja, LD did not extend past 100 kb; however, in the three cultivated G. max groups, LD extended from 90 to 574 kb, likely due to the impacts of domestication and increased self-fertilization. The three genomic regions were highly variable relative to the extent of LD within the three cultivated soybean populations. G. soja appears to be ideal for fine mapping of genes, but due to the highly variable levels of LD in the Landraces and the Elite Cultivars, whole-genome association analysis in soybean may be more difficult than first anticipated.

A neighbour-joining tree was constructed to determine the interspecific and intraspecific relationships in this data set. Almost all the peanut accessions in this data set classified into subspecies and botanical varieties such as subsp. hypogaea var. hypogaea, subsp. fastigiata var. fastigiata, and subsp. fastigiata var. vulgaris clustered with other accessions with the same classification, which lends further support to their current taxonomy. Alleles were sequenced from one of the SSR markers used in this study, which demonstrated that the repeat motif is conserved when transferring the marker across species borders. This study allowed the examination of the diversity and phylogenetic relationships in the peanut mini core which has not been previously reported.

Understanding their genome compositions is pivotal for efficient use of this vast gene pool in germplasm-enhancement programs. Several cleaved amplified polymorphic sequence (CAPS) markers were developed to distinguish the E-b, E-e, and R genomes. With the aid of disomic addition lines of wheat, it was confirmed that all 7 chromosomes of E-b, E-e, and R genomes carry these genome-specific CAPS markers. Thus, the identified CAPS markers are useful in detecting and monitoring the chromosomes of these 3 genomes. This study also provides evidence suggesting that some Purdue and Chinese germplasm lines developed for barley yellow dwarf virus (BYDV) resistance are different from those developed in Australia. Furthermore, Thinopyrum intermedium and Thinopyrum ponticum were shown to have different genome constitutions. Sequence analyses of the 1272 bp sequences, containing Ty3/gypsy retrotransposons, from the E-b, E-e, and R genomes also shed light on the evolution of these 3 genomes.

We have constructed a bacterial artificial chromosome (BAC) library of an advanced breeding line of white clover. The library contains 37 248 clones with an average insert size of approximately 85 kb, representing an approximate 3-fold coverage of the white clover genome based on an estimated genome size of 960 Mb. The BAC library was pooled and screened by polymerase chain reaction (PCR) amplification using both white clover microsatellites and PCR-based markers derived from Medicago truncatula, resulting in an average of 6 hits per marker; this supports the estimated 3-fold genome coverage in this allotetraploid species. PCR-based screening of 766 clones with a multiplex set of chloroplast primers showed that only 0.5% of BAC clones contained chloroplast-derived inserts. The library was further evaluated by sequencing both ends of 724 of the clover BACs. These were analysed with respect to their sequence content and their homology to the contents of a range of plant gene, expressed sequence tag, and repeat element databases. Forty-three microsatellites were discovered in the BAC-end sequences (BESs) and investigated as potential genetic markers in white clover. The BESs were also compared with the partially sequenced genome of the model legume M. truncatula with the specific intention of identifying putative comparative-tile BACs, which represent potential regions of microsynteny between the 2 species; 14 such BACs were discovered. The results suggest that a large-scale BAC-end sequencing strategy has the potential to anchor a significant proportion of the genome of white clover onto the gene-space sequence of M. truncatula.

In this study, we investigated the potential of the Moderate Resolution Imaging Spectroradiometer (MODIS) to capture the extent and distribution of peatlands in the St. Petersburg region of Russia by analyzing the relationships between peatland cover fractions derived from reference maps and similar to 1-km resolution MODIS Nadir BRDF-Adjusted Reflectance (NBAR) data from year 2002. First, we characterized and mapped 50 peatlands from forest inventory and peat deposit inventory data. The peatlands represent three major nutritional types (oligotrophic, mesotrophic, eutrophic) and different sizes (0.6-7800 ha). In addition, parts of 6 peatlands were mined for peat and these were mapped separately. The reference maps provided information on peatland cover for 1105 MODIS pixels. We performed regression analysis on 50% of the pixels and reserved the remainder for model validation. Canonical correlation analysis on the MODIS reflectance bands and the peatland cover fractions produced a multi-spectral peatland cover index (PCI), which served as the predictor in a reduced major axis (RMA) regression model. The results suggest a high potential for mapping peatlands with MODIS. The RMA regression models explained much of the variance in the PCI (r(2)=0.74 for mined and r(2)=0.81 for unmined peatlands). Model validation showed high correlation between observed versus predicted peatland cover (mined: r=0.87; unmined: r=0.92). We used the models to derive peatland cover estimates for the St. Petersburg region and compared the results to current MODIS land cover maps. (C) 2006 Elsevier B.V. All rights reserved.

Relationships according to ecosystem functional type are demonstrated between empirical and physiological parameters, suggesting linkages between easily estimated parameters and those with greater potential for process interpretation. Relatively sparse documentation of leaf area index dynamics at flux tower sites is found to be a major difficulty in model inversion and flux interpretation. Therefore, a simplification of the physiological model is carried out for a subset of European network sites with extensive ancillary data. The results from these selected sites are used to derive a new parameter and means for comparing empirical and physiologically based methods across all sites, regardless of ancillary data. The results from the European analysis are then compared with results from the other Northern Hemisphere sites and similar relationships for the simplified process-based parameter were found to hold for European, North American, and Asian temperate and boreal climate zones. This parameter is useful for bridging between flux network observations and continental scale spatial simulations of vegetation/atmosphere carbon dioxide exchange.

Here, we use a statistical modeling approach to partition the interannual variability in NEE (and its component fluxes, ecosystem respiration, R-eco, and gross photosynthesis, P-gross) into two main effects: variation in environmental drivers (air and soil temperature, solar radiation, vapor pressure deficit, and soil water content) and variation in the biotic response to this environmental forcing (as characterized by the model parameters). The model is applied to a 9-year data set from the Howland AmeriFlux site, a spruce-dominated forest in Maine, USA. Gap-filled flux measurements at this site indicate that the forest has been sequestering, on average, 190 g C m(-2) yr(-1), with a range from 130 to 270 g C m(-2) yr(-1). Our fitted model predicts somewhat more uptake (mean 270 g C m(-2) yr(-1)), but interannual variation is similar, and wavelet variance analyses indicate good agreement between tower measurements and model predictions across a wide range of timescales (hours to years). Associated with the interannual variation in NEE are clear differences among years in model parameters for both R-eco and P-gross. Analysis of model predictions suggests that, at the annual time step, about 40% of the variance in modeled NEE can be attributed to variation in environmental drivers, and 55% to variation in the biotic response to this forcing. As model predictions are aggregated at longer timescales (from individual days to months to calendar year), variation in environmental drivers becomes progressively less important, and variation in the biotic response becomes progressively more important, in determining the modeled flux. There is a strong negative correlation between modeled annual P-gross and R-eco (r=-0.93, P <= 0.001); two possible explanations for this correlation are discussed. The correlation promotes homeostasis of NEE: the interannual variation in modeled NEE is substantially less than that for either P-gross or R-eco.

These palustrine, depressional basin waters vacillate with regional drought and deluge, so surface water fluctuations over time modulate wetland productivity, habitat, and water quality functions. Models predict formidable effects of climate change on glacial basin surface waters, yet large-scale, long-term observation data are lacking to compare against predicted changes. Current, optical-based water detection models do not delineate marsh vegetation from shallow, turbid, high-chlorophyll waters common to the region. We developed a palustrine wetland spectral model for tracking open surface waters using Landsat imagery, which we evaluated for a 2500 km(2) landscape that estimates seasonal and annual open water variability for thousands of individual wetlands in the Missouri Coteau ecoregion. Detection accuracy of 96% was achieved for water bodies greater than a half-pixel in size. We identified shifts in the distribution of water permanence classes within and between years for waters emerging in spring, mid-summer, and late summer from 1997 to 2005 and identified a maximum of 19 047 basins with open water (12% of the landscape) populating 2500 km(2). For the 2005 growing season, we observed only 8757 basins with open water (6% of the landscape) for the same area. Declines were greatest for water bodies detected only in spring, suggesting a loss of those wetlands functioning to recharge groundwater stores early in the season and a high sensitivity to observed reductions in snowfall. If landscape factors driving open water coverage and wetland density are similar for the entire Missouri Coteau, we estimate the number of basins containing at least a pixel of water for this region declined from 577 600 to 266 000 between 1997 and 2005.

During the initial years of this period, agricultural scientists from the United States and elsewhere devoted considerable resources to collecting potential new crops for farmers as well as superior plants or cultivars of the species that farmers were already growing. Over time, there was a shift toward collecting unadapted germplasm, or raw material that possessed traits that plant breeders and other scientists could use for cultivar improvement and other types of research. Although many institutions and individuals were involved in plant collecting during this period, the creation of the U.S. Department of Agriculture (USDA) Office of Seed and Plant Introduction in 1898, resulted in the largest single program devoted to plant exploration. This office employed many individuals, including David Fairchild, P.H. Dorsett, Frank Meyer, Walter Swingle, and Wilson Popenoe. These and many other individuals collected-and introduced into the United States-seeds and plants of thousands of fruits, vegetables, nuts, ornamentals, cereals, forages, oilseeds, and other types of crops. Although the mission of most of the plant explorations during this period was to collect any plants that appeared interesting or potentially useful, others focused on collecting targeted species. Much of the material collected during this era is still maintained by the U.S. National Plant Germplasm System (NPGS), and much more of it shows up in the pedigrees of cultivars grown by farmers and gardeners today. In addition to collecting plants for immediate and future use, scientists of this era, such as Nicolai I. Vavilov and Jack Harlan, contributed greatly to the understanding of the evolution of plants and plant genetic diversity, and the interdependence of plants and civilization.

Foremost in this expansion was the addition of seven repositories for clonally propagated fruit and specialty crops. Many collections at state agricultural experiment station sites were in jeopardy as breeders retired. These collections can now be preserved by the NPGS. The NPGS has provided funding for plant exploration and exchange. From 1980 to 2004, 37 exploration/exchange proposals for fruit crops were funded, and over 3000 accessions introduced as a result. Crop Germplasm Committees (CGCs), established for each commodity have prepared genetic vulnerability statements and prioritized collection activities. The USDA ARS, National Germplasm Resources Laboratory (NGRL), facilitates international relationships, and the USDA Animal and Plant Health Inspection Service (APHIS), National Plant Germplasm Quarantine Center (NPGQC), tests and makes pathogen-tested germplasm available. As a result of the Convention on Biological Diversity (1993) and the International Treaty on Plant Genetic Resource for Food and Agriculture (2004), the USDA now pursues germplasm collection through the establishment of bilateral agreements of mutual benefit.

Cultivated fruit species have complex genome that will continue to require the input of novel genetic resources. Prospecting for wild fruit species will continue. The global nature of science and commerce will drive the demand to expand available genetic resources for fruit improvement. New technologies will enable future explorers to reach remote sites and species. Recent advances, such as geopositioning and remote-communication devices, will be used to a greater degree for targeting specific collection sites and documenting records of origin. The sovereignty of countries over their plant genetic resources, as specified by the Convention on Biological Diversity and the International Treaty on Plant Genetic Resources for Food and Agriculture, will continue to be a cornerstone for negotiating bilateral agreements and plant exchange. Although this could be considered a limitation to plant exploration in some situations, global strategies now in conceptual infancy will be developed to encourage and support ex situ preservation and continued plant exchange for long-term conservation and humanitarian benefit.

Matsum. & Nakai var. lanatus)) x United States Plant Introduction (PI) 386015 {Citrullus colocynthis (L.) Schrad.}]. One-hundred forty-six markers [randomly amplified polymorphic DNA (RAPD), intersimple sequence repeat (ISSR), amplified fragment length polymorphism (AFLP), and sequence-related amplified polymorphism (SRAP) markers] unique to NHM and representing different linkage groups on the map were tested for polymorphism among 24 watermelon cultivars limited in genetic diversity. Five (9.4%) of 53 RAPD, six (40.0%) of 15 ISSR, 30 (81.0%) of 37 AFLP, and 33 (80.5%) of 41 SRAP markers tested produced polymorphism among the 24 cultivars. The polymorphic markers used in this study are scattered throughout the watermelon genome. However, a large number (19 of the 30) of AFLP markers clustered on one linkage group on the map. The SRAP markers proved to be most effective in producing polymorphism and in representing different linkage regions of watermelon genome. The polymorphic markers represent all 10 large linkage groups and five of the nine small linkage groups (altogether 15 of 19 linkage groups) of the genetic linkage map constructed so far for watermelon. These polymorphic markers can be useful in DNA fingerprinting of cultivars, in testing seed purity of breeding lines, and in identifying triploid (seedless) hybrid watermelons derived from crosses between closely related tetraploid and diploid lines.

TI Estimating the relative abundance of flush shoots in citrus with implications on monitoring insects associated with flush SO HORTSCIENCE LA English DT Article DE Diaphorina citri; Phyllocnistis citrella; Toxoptera citricida; sampling; monitoring ID TREES AB Attention to the management of insects that feed on foliar flush growth has increased in Florida citrus as a result of the establishment of invasive plant diseases associated with insects that develop exclusively on flush. Citrus can be monitored to identify peak periods of flush abundance to time insecticide applications for these insects; however, guidelines for quantifying flush abundance are lacking. We therefore investigated sampling procedures for estimating flush abundance. A sampling method was devised to enable a quantitative estimation of flush shoots, defined as any shoot with immature leaves. A sample unit was the area within a 15 x 15 x 15-cm frame slipped into the outer edge of a tree with the end of a branch inside the frame. The number of flush shoots originating within the sample unit was counted. Three sample units were examined per tree in 45 randomly selected trees weekly during 2005 in each of two blocks of trees, one containing young 'Marsh' grapefruit (Citrus paradise Macf.) and one containing mature 'Temple' orange (tangors) [C. reticulate Blanco x C. sinensis (L.) Osbeck]. A pronounced abundance of flush was generally indicated by means of one or more flush shoots per sample in the particular trees studied. Variation in numbers of flush shoots per sample was similar within and among trees, differed significantly among sample dates, and did not differ significantly between the two blocks of trees overall sample dates. Taylor's power law coefficients indicated that, over all sample weeks, flush shoots were randomly distributed within the young grapefruit trees and only weakly aggregated within the block of mature oranges. Projections indicated that a sampling plan consisting of 40 trees (one sample per tree) would provide density estimates acceptable enough for general estimates at mean densities of one or more shoots per sample. An index of pest abundance based on mean pest density per flush shoot and mean density of flush shoots per sample is proposed.

Stock plants were harvested from native L. melissifolia populations growing in the lower Mississippi Alluvial Valley. In vitro proliferation was on woody plant medium supplemented with 1 mu M zeatin. After 6 weeks, zeatin level was increased to 5 mu M. Treatment of micropropagated shoots with a liquid auxin (2 indole-3-butyric acid : 1 1-naphthalenacetic acid) resulted in a low mean rooting percentage (<= 44%) compared with rooting in the absence of auxins and on a pure peat medium ex vitro, which increased rooting to >= 80%. Time to rooting was 8 weeks. Plants were acclimatized for 2 weeks, then potted in a 2 peat : 1 perlite medium supplemented with superphosphate, 10N-10P-10K, and Milorganite. Micropropagated L. melissifolia stecklings have been successfully outplanted in both controlled and field studies at the Center for Bottomland Hardwoods Research (Stoneville, Miss.).

Growing plants in containers, however, alters root growth and function and can change root morphology. Numerous factors influence root growth in containers. Roots of container-grown plants are subjected to temperature and moisture extremes not normally found in field production. The effects of substrate aeration (Ea) as well as water holding capacity (Pv) interact with different pot characteristics, resulting in changes to root morphology. Successful plant establishment after transplanting is often linked to root health. This review focuses on the roles of substrate physical and chemical properties, container characteristics, and temperature in altering root growth in container-grown woody nursery crops. Root circling, planting too deeply or "too-deep syndrome" (TDS), and the use of composts as container substrates will also be examined.

Cold storage at 1.1 degrees C was examined for possible control of three physiological larval states in 'Fuji' apples: diapausing (overwintering), diapause-destined, and nondiapausing. All nondiapausing larvae were dead within 12 weeks, diapaused-destined larvae were controlled by the seventh week, yet more than half of the original populations of diapausing larvae were still alive after I I weeks. Because the diapaused-destined larvae were younger than the nondiapausing larvae, they may have been more susceptible to cold. Because larvae normally diapause outside the fruit, cold storage would not be applicable for controlling larvae in this state. C1 USDA ARS, Yakima Agr Res Lab, Wapoto, WA 98951 USA.

This study was conducted to evaluate the growth of a popular container plant, calibrachoa (Calibrachoa x hybrida), produced in hanging flower pouches using different growing substrate compositions, polymer amendments, and the layering of substrate types of differing moisture holding capacity with the goal of achieving more uniform plant growth and improved after-sale maintenance. Plastic cylindrical hanging pouches were filled with one of nine hydrated substrate types or combinations. Rooted cuttings of 'Colorburst Violet' calibrachoa were planted as indicator plants to identify treatment effects because of their susceptibility to iron deficiency-induced chlorosis of new leaves. Daily measurements of substrate moisture were taken to determine the need for irrigation. Chlorophyll content was estimated nondestructively with a hand-held chlorophyll meter to determine the impact of moisture content. Light, porous substrates resulted in the most uniformly green plants and high numbers of flowers from top to bottom. A layered pouch with heavy, compost-amended substrate above a light, porous layer also produced high-quality, uniform plants. This enabled water to be distributed more uniformly throughout the container volume. This study provides fundamental information on how container geometry and soil moisture retention can influence water management decisions by the grower. C1 USDA ARS, Toledo, OH 43606 USA.

Results indicated there were an estimated 20,035 ha of blackberries planted and commercially cultivated worldwide, a 45% increase from 1995. Wild blackberries still make a significant contribution to worldwide production, with 8000 ha and 13,460 Mg harvested in 2004. There were 7692 ha of commercially cultivated blackberries in Europe, 7159 ha in North America, 1640 ha in Central America, 1597 ha in South America, 297 ha in Oceania, and 100 ha in Africa. Worldwide production of cultivated blackberries was 140,292 Mg in 2005. Of the blackberry area worldwide, 50% was planted to semierect cultivars, 25% to erect, and 25% to trailing types. 'Thornfree', 'Loch Ness', and 'Chester Thornless' were the most important sernierect types, and 'Brazos' and 'Marion' the most common erect and trailing types, respectively. In general, erect and sernierect cultivars are grown for fresh market and trailing cultivars for processing. Fresh fruit are usually picked into the final container in the field, whereas 75% of trailing blackberries for processing are picked by machine. Common production problems are reported. Production systems for field-grown blackberry differ with type grown and region. For example, in Mexico, production systems are modified to extend the production season for 'Tupy' and other erect-type cultivars from mid-October to June. Organic blackberry production is expected to increase from the 2528 ha planted in 2005. An estimated 315 ha of blackberries were grown under tunnels, mainly to protect against adverse weather and target high-priced markets. Based on this survey, there may be 27,032 ha of commercial blackberries planted worldwide in 2015, not including production from harvested wild plants.

TI Impacts of a volcanic eruption on the forest bird community of Montserrat, Lesser Antilles SO IBIS LA English DT Article ID MOUNT ST-HELENS; HURRICANE HUGO; WEST-INDIES; ASH; POPULATIONS; ACID; WASHINGTON; ORIOLE AB Volcanic eruptions are an important and natural source of catastrophic disturbance to ecological communities. However, opportunities to study them are relatively rare. Here we report on the effects of the eruption of the Soufriere Hills volcano on the forest bird community of the Lesser Antillean island of Montserrat. The island's species-poor avifauna includes 11 restricted-range species, including the Critically Endangered endemic Montserrat Oriole Icterus oberi. Analysis of monitoring data from 1997 to 2005 indicates that counts of most species were substantially lower following major ashfalls. However, this effect was short-lived, with rapid population recovery in subsequent years. Furthermore, levels of seasonal rainfall appear to have been at least as important in determining population trends as ashfall. Overall, most species were at least as abundant at the end of the study as at the start, and no forest bird species have been extirpated from Montserrat. We discuss potential ecological drivers of ashfall impacts on populations: there is some evidence that terrestrial foragers were most severely affected.

The objective was to automatically and objectively classify points within unclassified LiDAR point clouds, with few model parameters and minimal postprocessing. Presented is an automated method for classifying LiDAR returns as ground or nonground in forested environments occurring in complex terrains. Multiscale curvature classification (MCC) is an iterative multiscale algorithm for classifying LiDAR returns that exceed positive surface curvature thresholds, resulting in all the LiDAR measurements being classified as ground or nonground. The MCC algorithm yields a solution of classified returns that support bare-earth surface interpolation at a resolution commensurate with the sampling frequency of the LiDAR survey. Errors in classified ground returns were assessed using 204 independent validation points consisting of 165 field plot global positioning system locations and 39 National Oceanic and Atmospheric Administration-National Geodetic Survey monuments. Jackknife validation and Monte Carlo simulation were used to assess the quality and error of a bare-earth digital elevation model interpolated from the classified returns. A local indicator of spatial association statistic was used to test for commission errors in the classified ground returns. Results demonstrate that the MCC model minimizes commission errors while retaining a high proportion of ground returns and provides high confidence in the derived ground surface.

The extruded zein ribbon samples had between 10 and 15% triethylene glycol (TEG) and were conditioned at relative humidities between 23 and 70% before testing to determine the impact of sample testing direction on physical properties. Tensile strengths in the machine direction were between 18 and 64% higher than in the transverse direction. Elongations in the machine direction were between 33 and 291% higher than in the transverse direction. The magnitude of the difference between the machine and transverse direction was dependent on relative humidity and formulation. The impact of relative humidity was larger when the samples were tested in the machine direction; for example, tensile strength was reduced by 36% in the transverse direction and by 49% in the machine direction for the 15% TEG formulation when relative humidity was increased from 23 to 70%. With increased amounts of TEG, the magnitude of these differences was increased. The transverse direction tensile strength was reduced by 22% for a 10% TEG formulation, and by 36% for a 15% TEG formulation when relative humidity was increased from 23 to 70%. Polarized IR spectra of zein ribbons displayed differences between the spectra taken in the machine direction versus that taken in the transverse direction. Examination of the ribbons using polarizing light microscopy demonstrated that the ribbon was birefringent (delta n = 0.0004). These results demonstrate that molecular orientation occurred during extrusion and that orientation impacts physical properties. (C) 2007 Elsevier B.V. All rights reserved.

Aiton; PSR23) is a new oilseed crop rich in medium-chain fatty acids similar to tropical palms. Agronomic studies suggest that temperature is a key determinant of cuphea seed yields. However, little is known about the growth and photosynthesis response of cuphea to temperature. The following study is the first of its kind to evaluate cuphea's growth and photosynthesis response to temperature. Cuphea was grown under day/night temperature regimes of 18/12, 24/18, and 30/24 degrees C and regression analysis was used to assess its responses of growth and photosynthesis and determine their optimum temperature range. Vegetative growth and leaf photosynthesis adapted well over the temperature range studied. However, reproductive growth was more sensitive showing a decline with increasing temperature. Reproductive growth rate was greatest under the lowest (18/12 degrees C) temperature treatment and declined by 43% at the highest growth temperatures. In contrast, vegetative growth, which was greatest under the 24/18 degrees C treatment, declined by just 25 and 10% at the lowest and highest temperatures, respectively. Photosynthesis acclimated to temperature by up-regulation of in vivo Rubisco activity with declining growth temperature. Maximum Rubisco activity (V-cmax) in leaves under the 18/12 degrees C treatment was 76% greater than that of leaves grown at 30/24 degrees C. Photosynthetic acclimation permitted cuphea to vegetatively grow well over a wide temperature range, but does not explain the sensitivity of reproductive growth to temperature, which will require further research to elucidate.

A 931 bp cDNA encoding a putative 297-residue beta-1,3-galactosyltransferase (beta 3GAT5) was cloned from larval Ostrinia nubilalis midgut tissue, and showed homology to Drosophila brainiac (brn) and Caenorhabditis elegans bre5 proteins. Single nucleotide polymorphisms (SNPs) were detected in coding and promoter regions of O. nubilalis beta 3GalT5 (Onb3GalT5), of which 3 of 31 CDs SNPs were non-synonymous. SNPs within HaeIII and MspI recognition sites were confirmed by PCR-RFLP, and are Mendelian inherited. Analysis of F-2 pedigrees suggested an Onb3GalT5 SNP C660 fixed within a Cry1Ab-resistant colony was not correlated with Cry1Ab resistance traits, as measured by higher larval O. nubilalis weights when fed toxin-containing diet.

TI Trap catches of the sweetpotato whitefly (Homoptera : Aleyrodidae) in the Imperial Valley, California, from 1996 to 2002 SO INSECT SCIENCE LA English DT Article DE Bemisia tabaci biotype B; CC trap; cotton; melons; ornamentals ID BEMISIA-ARGENTIFOLII HOMOPTERA; TABACI; MANAGEMENT; DISPERSAL; FLIGHT AB An outbreak of the sweetpotato whitefly, Bemisia tabaci (Gennadius), biotype B occurred in the Imperial Valley, California in 1991. The insects destroyed melon crops and seriously damaged other vegetables, ornamentals and row crops. As a result of the need for sampling technology, we developed a whitefly trap (named the CC trap) that could be left in the field for extended time periods. We used the traps to monitor populations of B. tabaci adults during year-round samplings from 1996 to 2002 to study variations in the weekly trap catches of the insect. The greatest number of B. tabaci adults was recorded in 1996, followed by a continuing annual decrease in trap catches each year through 2002. The overall decline of B. tabaci is attributed in part to the adoption of an integrated pest management (IPM) program initiated in 1992 and reduced melon hectares from 1996 to 2002. Other factors may also have contributed to the population reductions. Seasonally, B. tabaci trap catches decreased during the late summer and fall concurrent with decreasing minimum temperatures that are suggested to be a significant factor affecting seasonal activity and reproduction.

For Arcobacter, 93.7% (n = 163) were resistant to one or more antimicrobials and 71.8% (it = 125) were resistant to two or more antimicrobials. For Canupylobacter, 99.5% (n = 214) were resistant to one or more antimicrobials and 28.4% (n = 6 1) were resistant to two or more antimicrobials. Arcobacter butzleri isolates were particularly resistant to clindamycin (90%; n = 126), azithromycin (81.4%; n = 114) and nalidixic acid (23.6%; n = 33). Resistance to tetracycline was very high in Campylobacter jejuni (99.5%) and Campylobacter coli (96.3%).

We examined 9cRA and 1,25D, alone and in combination, for their potential to inhibit carcinogen (NNK)-induced lung carcinogenesis in A/J mice. A/J mice (n = 14/group) were treated with 9cRA (7.5, 15, or 30 mg/kg diet), 1,25D (2.5 or 5.0 pg/kg diet), or a combination of 9cRA (15 mg/kg diet) plus 1,25D (2.5 pg/kg diet) for 3 weeks before and 17 weeks after carcinogen injection. Lung tumor incidence, tumor multiplicity, plasma 1,25D levels and kidney expression of vitamin D 24-hydroxylase (CYP24) were determined. Compared to carcinogen-injected controls, mice receiving 9cRA supplementation had significantly lower tumor multiplicity at all doses (decreased 68-85%), with body weight loss at the higher doses of 9cRA. Mice receiving 1,25D supplementation had significantly lower tumor incidence (decreased 36 and 82%) and tumor multiplicity (decreased 85 and 98%), but experienced significant body weight loss, kidney calcium deposition, elevated kidney CYP24 expression and decreased fasting plasma 1,25D levels. Although, there was no apparent influence on chemopreventive efficacy, addition of 9cRA to 1,25D treatment effectively prevented the weight loss and kidney calcification associated with 1,25D treatment alone. These data demonstrate that 9cRA and 1,25D, alone or combined, can inhibit lung tumor promotion in the A/J mouse model. Combining 1,25D with 9cRA has the potential to mitigate the toxicity of 1,25D, while preserving the significant effect of 1,25D treatment against lung carcinogenesis. The underlying mechanism behind this effect does not appear to be related to retinoid modulation of vitamin D catabolism. (c) 2007 Wiley-Liss, Inc.

Methods: Data from two 24-h dietary recalls from individuals reporting physiologically plausible energy intake (within +/- 22% of predicted energy requirements, based on previously published methods) were used. Results: Mean reported energy intake was 96 and 95% of predicted energy requirements in younger and older subjects, respectively. Older subjects were less likely than younger subjects to skip a meal, but snacking was common in both age groups. Fiber density was significantly higher in the older group. A higher BMI in both age groups was associated with a higher total daily energy intake, and higher energy intakes at all eating occasions. In both age groups, eating frequency was positively associated with energy intake, and eating more than three times a day was associated with being overweight or obese. In the younger group but not the older group, a lower fiber density coupled with higher percentage of energy from fat was independently associated with having a higher BMI. Conclusions: While no one eating occasion contributes more than any other to excess adiposity, eating more often than three times a day may play a role in overweight and obesity in both younger and older persons. A reduced satiety response to dietary fiber in addition to lower energy expenditure may potentially further contribute to weight gain in older persons.

The bacterium, designated strain PPC9(T), was facultatively anaerobic and had a DNA G + C content of 44.5 mol%. Comparative 16S rRNA gene sequencing indicated that the bacterium represented a novel subline within the genus Vagococcus, close to but distinct from Vagococcus lutrae. Strain PPC9(T) was readily distinguished from the five recognized species of the genus Vagococcus by using biochemical tests and molecular genetic analysis. Based on phylogenetic and phenotypic evidence strain PPC9(T) is considered to represent a novel species of the genus Vagococcus, for which the name Vagococcus elongatus sp. nov. is proposed. The type strain is PPC9(T) (= CCUG 51432(T) = NRRL B-41357(T)). C1 Univ Oklahoma, Dept Bot & Microbiol, Norman, OK 73019 USA.

To report the macular pigment optical density (MPOD) findings at 0.5 degrees of eccentricity from the fovea in elderly subjects participating in ARMA, a study of aging and age-related maculopathy (ARM) ancillary to the Health, Aging, and Body Composition (Health ABC) Study. METHODS. MPOD was estimated with a heterochromatic flicker photometry (HFP) method in a large biracial population sample of normal 79.1 +/- 3.2-year-old adults living in the Midsouth (n = 222; 52% female; 23% black, 34% users of lutein-containing supplements). Within a modified testing protocol, subjects identified the lowest and the highest target intensity at which the flicker sensation disappeared, and the exact middle of this "no-flicker zone" was interpolated by the examiner. RESULTs. An MPOD estimate was obtained successfully in 82% of the participants. The mean MPOD in our sample was 0.34 +/- 0.21 (SD). The interocular correlation was high (Pearson's r = 0.82). Compared with lutein supplement users, mean MPOD was 21% lower in nonusers (P = 0.013). MPOD was also 41% lower in blacks than in whites (P = 0.0002), even after adjustment for lutein supplement use. There were no differences in MPOD by gender, iris color, or history of smoking. CONCLUSIONs. Older adults in the Midsouth appear to have average MPOD and interocular correlation comparable to those in previous studies. Lutein supplement use and white race correlated with higher MPOD. No evidence of an age-related decline in MPOD was seen in the sample. The HFP method for the measurement of MPOD is feasible in epidemiologic investigations of the elderly, the group at highest risk of ARM.

Host plant resistance is widely considered a desirable method for reducing losses to this pest. Nine inbred lines were evaluated for resistance to ear damage, larval survival, and weight of larvae. Mp313E and Mp717 sustained less damage than the other lines, and larval survival and growth on these lines was reduced. Analysis of a diallel cross among the nine lines indicated that both general combining ability (GCA) and specific combining ability (SCA) were significant sources of variation in the inheritance of resistance to ear damage. GCA was also a significant source of variation in the inheritance of resistance to larval growth. GCA effects for reduced larval weight were significant for Mp313E and Mp717. These lines could be useful in the development of maize hybrids with corn earworm resistance. C1 [Matthews, Gerald A.; Williams, W.

TI Treatment of Pastures with Diflubenzuron Suppresses Horn Fly, Haematobia irritans (Diptera: Muscidae) Development SO JOURNAL OF AGRICULTURAL AND URBAN ENTOMOLOGY LA English DT Article DE horn fly; Haematobia irritans; diflubenzeron AB Diflubenzuron is an insect growth regulator labeled for application to pastures and rangeland to suppress grasshopper (Orthoptera: Acrididae) populations. Livestock are permitted access to land immediately after treatment. We hypothesized the development and survivorship of horn fly Haematobia irritans (L.) larvae feeding on manure resulting from these animals would not be impacted due to the presence of diflubenzuron residue. Survivorship to the adult stage and percent pupae deformed were recorded for horn flies developing on manure samples from three pastures treated with 59 ml Dimilin 2L (R)/0.4 hectares. Pastures not treated served as the controls. Manure samples ranged in age from three to 31 d post treatment. This study was replicated in 2004 and 2005. Results were highly variable between site and year. Horn fly survivorship to the adult stage in 11 of 15 sample dates taken was lower in treated than the control manure samples. Accordingly, a significantly greater percentage of deformed Pupae was recorded for samples from the treated than the control sites <= 17 d post treatment. Based on this study, our null hypothesis was rejected. Using Dimilin 2L to suppress pasture and range land pests can also impact horn fly populations associated with cattle feeding in these pastures. However, care should be taken to apply adequate pasture coverage ensuring appropriate Dimilin 2L (R) levels are consumed to achieve the suppression of associated horn flies. C1 [Tomberlin, J.

TI Use of spatial analyses for global characterization of wheat-based production systems SO JOURNAL OF AGRICULTURAL SCIENCE LA English DT Article; Proceedings Paper CT International Workshop on Increasing Wheat Yield Potential CY MAR 20-24, 2006 CL Obregon, MEXICO SP CIMMYT ID GEOGRAPHIC INFORMATION-SYSTEMS; AFFECTING GRAIN-SORGHUM; MAIZE ENVIRONMENTS; CLASSIFICATION; GENOTYPE; PATTERNS; CLIMATE; AREAS AB CIMMYT (International Maize and Wheat Improvement Centre) and other research groups within the Consultative Group for International Agricultural Research (CGIAR) have made major contributions to agricultural development, e.g. underpinning the 'green revolution', but it is unlikely they will continue making such far-reaching contributions without the ability to collect, analyse and assimilate large amounts of spatially orientated agronomic and climatic data. Increasingly, application of modern tools and technologies are crucial elements in order to support and enhance the effectiveness of international agricultural research. Bread and durum wheats (Triticum aestivion and Triticum durum) occupy an estimated 200 million ha globally, are grown from sea level to over 3500 m asl, and from the equator to latitudes above 60 degrees N in Canada, Europe, and Asia. For organizations like CIMMYT, which seek to improve wheat production in the developing world, understanding the geographic context of wheat production is crucial for priority setting, promoting collaboration, and targeting germplasm or management practices to specific environments. Increasingly important is forecasting how the environments, and their associated biotic and abiotic stress patterns, shift with changing climate patterns. There is also a growing need to classify production environments by combining biophysical criteria with socio-economic factors. Geospatial technologies.. especially geographic information systems (GIS), are playing a role in each of these areas, and spatial analysis provides unique insights. Use of GIS to characterize wheat production environments is described, drawing from examples at CIMMYT. Since the 1980s, the CIMMYT wheat programme has classified production regions into mega-environments (MEs) based on climatic, edaphic, and biotic constraints. Advances in spatially disaggregated datasets and GIS tools allow MEs to be characterized and mapped in a much more quantitative manner. Parallel advances are improving characterizations of the actual (v. potential) distribution of major crops, including wheat. The combination of improved crop distribution data and key biophysical data at high spatial resolutions also permits exploring scenarios for disease epidemics, as illustrated for the stem rust race Ug99. Availability of spatial data describing future climate conditions may provide insights into potential changes in wheat production environments in the coming decades. There is a pressing need to advance beyond static definitions of environments and incorporate temporal aspects to define locations or regions in terms of probability or frequency of occurrence of different environment types. Increased availability of near real-time daily weather data derived from remote sensing should further improve characterization of environments, as well as permit regional-scale modelling of dynamic processes such as disease progression or crop water status.

TI Evaluation of experimental methods for manipulating chicken egg hormone content using injections SO JOURNAL OF ANIMAL AND VETERINARY ADVANCES LA English DT Article DE chicken; embryo; mortality; prenatal stress ID EMBRYONIC-DEVELOPMENT; CORTICOSTERONE; GROWTH; ALCOHOL AB To study the effects and mechanisms of pre-hatch stress in hens it is important to have reliable methodology that can be used to illuminate effects of embryonic hormonal exposure without seriously compromising the viability of embryos. This experiment aimed to develop methods that can be used for injecting corticosterone into eggs prior to incubation without greatly reducing hatchability. The injection method involved application of a small amount of silicone sealant to the apical end of eggs, insertion of a needle through this seal to a depth of 5 mm into the albumen and injection of a sesame oil vehicle with or without corticosterone. It is shown that corticosterone can be injected with a resulting mortality of 38%. The applicability of these methods are discussed and will be further used to test for effects of corticosterone injections prior to incubation on behaviour and morphology in laying hens.

The initial version of this software package, however, was generally limited to pedigree-based relationships. With continued advances in genomic research and the increased availability of genotyping, relationships based on molecular markers are obtainable and desirable. The addition of a new program to the set of multiple-trait derivative-free REML programs is described that allows users the flexibility to calculate relationships using standard pedigree files or an arbitrary relationship matrix based on genetic marker information. The strategy behind this modification and its design is described. An application is illustrated in a QTL association study for canine hip dysplasia.

Validation was interpreted to be the independent confirmation of the associations between genetic tests and phenotypes, as claimed by the commercial genotyping companies. Validation of the quality grade test (GeneSTAR Quality Grade) was carried out on 400 Charolais x Angus crossbred cattle, and validation of the tenderness tests (GeneSTAR Tenderness and Igenity TenderGENE) was carried out on over 1,000 Bos taurus and Bos indicus cattle. The GeneSTAR Quality Grade marker panel is composed of 2 markers (TG5, a SNP upstream from the start of the first exon of thyroglobulin, and QG2, an anonymous SNP) and is being marketed as a test associated with marbling and quality grade. In this validation study, the genotype results from this test were not associated with marbling score; however, the association of substituting favorable alleles of the marker panel with increased quality grade (percentage of cattle grading Choice or Prime) approached significance (P <= 0.06), mainly due to the effect of 1 of the 2 markers. The GeneSTAR Tenderness and Igenity TenderGENE marker panels are being marketed as tests associated with meat tenderness, as assessed by Warner-Bratzler shear force. These marker panels share 2 common mu-calpain SNP, but each has a different calpastatin SNP. In both panels, there were highly significant (P < 0.001) associations of the calpastatin marker and the mu-calpain haplotype with tenderness. The genotypic effects of the 2 tenderness panels were similar to each other, with a 1 kg difference in Warner-Bratzler shear force being observed between the most and least tender genotypes. Unbiased and independent validation studies are important to help build confidence in marker technology and also as a potential source of data required to enable the integration of marker data into genetic evaluations. As DNA tests associated with more beef production traits enter the marketplace, it will become increasingly important, and likely more difficult, to find independent populations with suitable phenotypes for validation studies.

A hull-less LPB, M422-H, which was not near-isogenic to the other cultivars, was also evaluated. Apparent nutrient balance, bone measurements, and growth performance were the response criteria evaluated. The barrows were fed the diets to appetite in meal form in individual metabolism crates. Barley and soybean meal were the only sources of phytic acid. Dietary protein supplementation and ME/kg were equalized in all diets. The treatments were diets containing NB, M422, M635, or M422-H without or with added inorganic P (iP), or M955 without added iP. Diets with added iP contained 0.30% available P (aP), the same concentration of aP provided by the diet containing M955 without added iP. There were linear increases (P <= 0.02) in ADG, GY, metacarpal and radius bone strength, and fat-free dry weight, and in the absorption and retention (g/d and % of intake) of P and Ca with increasing dietary concentration of aP from the near-isogenic cultivars NB, M422, M635, or M955 without added iP. There were linear decreases in the grams (P <= 0.02) and percentages (P < 0.001) of P and Ca excreted per day with increasing dietary concentration of aP without added iP. There were no responses for N or energy balance. Growth performance and bone response criteria did not differ for barrows fed the diet containing M955 or the near-isogenic diets containing NB, M422, or M635 with added iP. However, barrows fed the diet containing M955 had greater (P <= 0.02) percentages of P, N, and energy absorption and retention, Ca absorption, and DM digestibility and had less (P <= 0.02, g/d and %) excretion of P, N, energy, and Ca (g) per day than barrows fed the diets containing the near-isogenic NB or LPB cultivars with added iP. When dietary aP was equalized with iP, the excretion of P in feces plus urine (g/d) was reduced by 20.2, 27.9, and 44.6%, respectively, in barrows fed the diets containing M422 + iP, M635 + iP, or M955 compared with barrows fed the diet containing NB + iP. Energy utilization did not differ for barrows fed the diets containing hulled or hull-less LPB when ME/kg was equalized with lard. In conclusion, the apparent utilization of P and Ca, the bone strength and fat-free dry weight, and growth performance increased with increasing dietary concentration of aP provided by LPB, in association with linear decreases in P and Ca excretion. Barrows fed the diet containing M955 also had greater utilization and less excretion of P, Ca, N, energy, and DM than barrows fed the diets containing the near-isogenic NB or LPB cultivars with added iP to equalize aP at 0.30%.

Chronic indwelling catheters were surgically implanted in the abdominal aorta, a mesenteric vein, a hepatic vein, and the portal vein of 18 growing Dorset x Suffolk wethers (44.6 +/- 3.6 kg of BW). Wethers had ad libitum access to the following diets in a completely randomized block design: 1) Low (9.9% CP), 2) Medium (12.5% CP), or 3) Low and High (14.2% CP) diets oscillated on a 48-h interval (Osc). Dry matter intake was greater (P = 0.04) for the Osc diet (1,313 g/d) than the Low diet (987 g/d) and was intermediate for the Medium diet (1,112 g/d). Nitrogen intake was not different between the wethers fed the Osc (25.4 g/d) and Medium diets (22.2 g/d), but was lower (P < 0.01) in wethers fed the Low diet (16.0 g/d). Wethers fed the Osc diet (6.7 g/d) retained more (P < 0.04) N than did those fed the Medium diet (4.0 g/d). Hepatic arterial blood flow was not different (P = 0.81) between wethers fed the Osc (31 L/h) or Medium diet (39 L/h) but was greater (P = 0.05) in wethers fed the Low diet (66 L/h). Net release of alpha-amino N by the PDV did not differ (P = 0.90) between the Low (37.8 mmol/h) and Medium diets (41.5 mmol/ h) or between the Osc (53.0 mmol/h) and Medium diets (P = 0.29). Net PDV release of ammonia N was less (P = 0.05) for the Low diet than for the Medium diet, and this was accompanied by a similar decrease (P = 0.04) in hepatic ammonia N uptake. Urea N concentrations tended to be (P = 0.06) less in arterial, portal, and hepatic blood in wethers fed the Low diet compared with those fed the Medium diet. Wethers fed the Osc diet tended (P = 0.06) to have a greater PDV uptake of urea N than did those fed the Medium diet, but there was no difference between the Osc and Medium diets (P = 0.72) in hepatic urea N release. Net PDV uptake of glutamine tended to be greater (P < 0.07) in wethers fed the Low diet (6.7 mmol/h) than those fed the Medium diet (2.7 mmol/h). These data indicate that oscillating dietary protein may improve N retention by increasing endogenous urea N uptake by the gastrointestinal tract.

TI Salvage of blood urea nitrogen in sheep is highly dependent on plasma urea concentration and the efficiency of capture within the digestive tract SO JOURNAL OF ANIMAL SCIENCE LA English DT Article DE digestive tract; nitrogen metabolism; ruminant; urea kinetics ID GASTROINTESTINAL-TRACT; RUMINAL WALL; BEEF STEERS; METABOLISM; RUMEN; PROTEIN; KINETICS; FLUX; HAY AB The aims of this study were 1) to determine whether transfer of blood urea to the gastrointestinal tract (GIT) or the efficiency of capture of urea N within the GIT is more limiting for urea N salvage, and 2) to establish the relationship between plasma urea concentration and recycling of urea N to the GIT. We used an i.v. urea infusion model in sheep to elevate the urea entry rate and plasma concentrations, thus avoiding direct manipulation of the rumen environment that otherwise occurs when feeding additional N. Four growing sheep (28.1 +/- 0.6 kg of BW) were fed a low-protein (6.8% CP, DM basis) diet and assigned to 4 rates of i.v. urea infusion (0, 3.8, 7.5, or 11.3 g of urea N/d; 10-d periods) in a balanced 4 x 4 Latin square design. Nitrogen retention (d 6 to 9), urea kinetics ([N-15(2)]urea infusion over 80 h), and plasma AA were determined. Urea infusion increased apparent total tract digestibility of N (29.9 to 41.3%) and DM (47.5 to 58.9%), and N retention (1.45 to 5.46 g/d). The plasma urea N entry rate increased (5.1 to 21.8 g/d) with urea infusion, as did the amount of urea N entering the GIT (4.1 to 13.2 g/d). Urea N transfer to the GIT increased with plasma urea concentration, but the increases were smaller at greater concentrations of plasma urea. Anabolic use of urea N within the GIT also increased with urea infusion (1.43 to 2.98 g/d; P = 0.003), but anabolic use as a proportion of GIT entry was low and decreased (35 to 22%; P = 0.003) with urea infusions. Consequently, much (44 to 67%) of the urea N transferred to the GIT returned to the liver for resynthesis of urea (1.8 to 9.2 g/d; P < 0.05). The present results suggest that transfer of blood urea to the GIT is 1) highly related to blood urea concentration, and 2) less limiting for N retention than is the efficiency of capture of recycled urea N by microbes within the GIT.

Twelve ewes (mean BW = 46 2 kg) were fed a diet containing either high endophyte-infected (HI-E) or low endophyte-infected (LO-E) tall fescue seed for 7 d. Each diet consisted of 50% (as-fed basis) tall fescue seed. Ewes were experimentally inoculated with antibiotic resistance-selected E. coli O15TH7 on d 1 of the feeding treatment, and fecal shedding of inoculated pathogens was monitored daily on d 2 to 6. On d 7, ewes were weighed and euthanized, and tissues and contents were sampled from the ileum, cecum, and rectum for quantitative enumeration of E. coli O157:H7. Urine was collected at euthanization to determine total ergot alkaloid concentrations. Ewes fed HI-E had lower (P < 0.001) DMI than did ewes fed LO-E (0.8 and 1.6 +/- 0.1 kg/d of DMI for HI-E and LO-E ewes, respectively); consequently, there was a tendency (P = 0.06) for HLE ewes to lose 0.3 +/- 0.4 kg of BW/d and LO-E ewes to gain 0.2 0.4 kg of BW/d during the 7 d. Urinary ergot alkaloids were increased (P < 0.001) in ewes fed HI-E (47.8 +/- 9.4 ng/mg of creatinine) compared with those fed LO-E (6.2 +/- 9.4 ng/mg of creatinine). Prolactin tended (P = 0.06) to be decreased in ewes fed HI-E (7.2 +/- 7.0 ng/mL) compared with those fed LO-E (27.7 +/- 7.0 ng/mL). Fecal shedding of E. coli O157:H7 tended (P = 0.06) to be increased in HI-E ewes [5.4 cfu (log(10))/g of feces] compared with LO-E ewes [4.5 cfu (log(10))/g of feces]. The population of E. coli O157:H7 in luminal contents from the ileum, cecum, and rectum did not differ (P > 0.36) between treatments. Treatment did not influence (P = 0.30) the occurrence of E. coli O157:H7 in cecal or rectal tissues; however, ileal tissues from HI-E ewes tended (P = 0.12) to have an increased incidence of E. coli O157:H7. Concentrations of NEFA tended (P = 0.12) to be greater in HI-E ewes than in LO-E ewes, whereas cortisol was similar (P = 0.49) for HI-E and LO-E ewes. We conclude that short-term feeding of HI-E tall fescue seed may alter the concentrations of prolactin and NEFA, and may increase fecal shedding of E. coli O15TH7 in experimentally inoculated ewes.

Anise, rose/grape seed, and tea tree oils were more attractive than unbaited traps but none approached the attractiveness of Advanced Pheromone Technologies' AFF lure, a synthetic food-odour lure that emits several nitrogenous chemicals attractive to this fly. Traps baited with most of the oils were less attractive than unbaited traps. Rose/grape seed oil and pure-rose oil enhanced attractiveness of AFF lures to both males and females by about 68%. Grape seed oil did not enhance the attractiveness of AFF lures demonstrating that rose oil was the active component of the rose/grape seed oil. No other oil enhanced attractiveness of AFF lures and most decreased attraction to AFF lures. The possibility that highly attractive chemicals may be present in rose oil as minor components is discussed. Traps baited with the combination of clove bud oil and the AFF lure captured only 3% as many flies as traps baited only with the AFF lure indicating that clove bud oil is highly repellent to Mexican fruit flies.

Methods and Results: Water chemistry was monitored weekly for nitrate, orthophosphate, and suspended solids, at various sites throughout the wetland for 6 months. Treatment ponds with 50% plant cover had about a 96.3% nitrate removal. The average change between the influent and effluent was 50-60% nitrate removal and 40-50% orthophosphate removal. Community profile of total DNA, generated by using denaturing gradient gel electrophoresis (DGGE), was used to determine the major microbial composition associated with the wetland sediment, rhizosphere, and surface water. Bacterial cloned libraries were constructed, and 300 clones were analysed by amplified ribosomal DNA restriction analysis (ARDRA) and grouped into operational taxonomic units (OTUs). A total of 35, 31, and 36 different OTU were obtained from sediment, rhizosphere, and surface water, respectively. The bacterial members within the dominant group of our clone library belonged to unclassified taxa, while the second predominant group consisted of members of the phylum Proteobacteria. The dominant organisms within the class were in the gamma, beta, and delta classes. Conclusion: Microbial diversity as determined by Shannon-Weaver index (H) was higher in the wetland cells with 50% plant density than the 100%. This was in agreement with the most efficient wetland contaminant removal units. Significance and Impact of the Study: This study provides evidence that wetlands with 50% plant cover may promote the growth of diverse microbial communities that facilitate decomposition of chemical pollutants in surface water, and improve water quality.

Methods and Results: Quantitative, real-time PCR with group-specific 16S rDNA primer sets was used to enumerate the abundance of the following chicken gastrointestinal (GI) tract phylogenetic groups: the Clostridium leptum-Faecalibacterium prausnitzii subgroup (Clostridium genus cluster IV), the Clostridium coccoides-Eubacterium rectale subgroup (Clostridium cluster XIVa and XIVb), the Bacteroides group (including Prevotella and Porphyromonas), Bifidobacterium spp., the Enterobacteriaceae, the Lactobacillus group (including the genera Leuconostoc, Pediococcus, Aerococcus and Weissella), the Clostridium perfringens subgroup (Clostridium cluster I), Enterococcus spp., Veillonella spp., Atopobium spp., Campylobacter spp. and the domain Bacteria. A species-specific 5'-nuclease (Taqman) assay was also employed to specifically assess Cl. perfringens abundance. Ten birds were sampled from each of two commercial chicken houses, one in which feed was supplemented with AGPs and exogenous animal protein, and the other vegetable-based and drug-free, at 7, 14 and 21 days of age. The ileal community was dominated by two large populations, the lactobacilli and the Enterobacteriaceae, with those taxa much more numerous in drug-free vegetable-based diet fed birds than those conventionally reared at the 7- and 14-day time periods. The progressive changes in microflora in both the conventional and drug-free caeca were similar to each other, with the Enterobacteriaceae sequences dominating at day 7, but being replaced by obligate anaerobe signature sequences by day 14. Of note was the finding that all the day 14 and day 21 replicate caecal samples from the drug-free house were positive for Campylobacter spp. averaging > 10(8) 16S rDNA gene copies per gram wet weight. Conclusions: Quantitative, real-time PCR indicates that the effects of drug-free rearing on the chicken GI tract microbial community are most pronounced in the ileal region, but AGPs may be important in controlling Campylobacter colonization of the caecum. Significance and Impact of the Study: A quantitative taxonomic understanding of the shifting microbial ecology of the broiler chicken gut microbiota is important in the light of AGP withdrawal. AGP withdrawal has occurred in response to concerns over the transfer of antimicrobial-resistant bacteria to humans via the food production chain.

TI An object-based image analysis approach for determining fractional cover of senescent and green vegetation with digital plot photography SO JOURNAL OF ARID ENVIRONMENTS LA English DT Article DE rangeland vegetation; rangeland monitoring; very high-resolution images; object-based image analysis ID GROUND-COVER; SEGMENTATION; TEXTURE AB Research into automatic image processing of digital plot photography has increased in recent years. However, in most studies only overall vegetation cover is estimated. In and regions of the southwestern US, grass cover is typically a mixture of green and senescent plant material and it is important to be able to quantify both types of vegetation. Our objectives were to develop an image analysis approach for estimating fractional cover of green and senescent vegetation using very high-resolution ground photography, and to compare image-based estimates with line-point-intercept (LPI) measures. We acquired ground photography for 50 plots using an eight megapixel digital camera. The images were transformed from the RGB (red, green, blue) color space to the IHS (intensity, hue, saturation) color space. We used an object-based image analysis approach to classify the. images into soil, shadow, green vegetation, and senescent vegetation. Shadow and soil were effectively masked out by using the intensity and saturation bands, and a nearest neighbor classification was used to separate green and senescent vegetation using intensity, hue and saturation as well as visible bands. Correlation coefficients between LPI- and image-based estimates for green and senescent vegetation were 0.88 and 0.95 respectively. Image analysis underestimated total and senescent vegetation by approximately 5%. The object-based image-processing approach is less labor and time intensive than the LPI method, is a viable alternative to ground-based methods, and has the potential to be incorporated into rangeland monitoring protocols.

TI Wind erosion quantity and quality of an Entic Haplustoll of the semi-arid pampas of Argentina SO JOURNAL OF ARID ENVIRONMENTS LA English DT Article DE wind erosion; erosion quantity; erosion quality; semi-arid regions; loess soils ID ORGANIC-MATTER; PHYSICAL CHARACTERISTICS; WINDBLOWN SEDIMENT; SOIL PRODUCTIVITY; NUTRIENTS; TRANSPORT AB Wind erosion is said to be an important degradation process of soils, but little is known about the magnitude of this process and its effect on soil nutrient transport in Entic Haplustolls of the semia-arid Pampas of Argentina. The objective of this study was to measure the rate of wind erosion and the concentration of nitrogen and phosphorus in the sediment originating from different tillage systems: conventional tillage (CT), vertical tillage (VT), and no-till (NT), for two different crops of the semi-arid Pampas of Argentina. Measurements of airborne sediment were carried out in an 8 ha field using Big Spring Number Eight (BSNE) samplers, in two periods of 1998 and 1999, after seeding sunflower (Helianthus annus) and rye (Secale cerale). Losses and accumulations of material were detected. Losses varied between 4 and almost 900 kg ha(-1), and accumulations between 3 and 580 kg ha(-1). Wind erosion was higher in 1999 than in 1998 in all tillage systems, due to higher wind speeds and lower plant residue coverage of the first measurement period. In 1999, erosion was lower in plots with higher plant residue coverage (NT against CT), and in 1998 sediment accumulation was observed in these treatments. Nitrogen concentration in the sediment collected at greater heights increased and phosphorus concentration decreased with wind speed. This was due to the accumulation of nitrogen in the coarsest aggregates and of phosphorus in the finer aggregates. The nitrogen enrichment of the sediment varied between 2 and 5, while the phosphorus enrichment varied between 1.5 and 8. The nitrogen enrichment increased and the phosphorus enrichment decreased with wind speed. Lower wind-speed storms will erode relatively more phosphorus than nitrogen. When high wind-speed storms occur, nitrogen becomes more susceptible to erosion. Wind speed is the variable that may regulate the amounts of nutrient loss. (c) 2006 Elsevier Ltd. All rights reserved.

An increasing number of phylogeographical studies in the Arctic have laid a framework for testing hypotheses concerning the impact of shifting environmental conditions on transcontinental movement. We review 35 phylogeographical studies of trans-Beringian terrestrial and freshwater taxa, both hosts and parasites, to identify generalized patterns regarding the number, direction and timing of trans-continental colonizations. We found that colonization across Beringia was primarily from Asia to North America, with many events occurring in the Quaternary period. The 35 molecular studies of trans-Beringian organisms we examined focused primarily on the role of glacial cycles and refugia in promoting diversification. We address the value of establishing testable hypotheses related to high-latitude biogeography. We then discuss future prospects in Beringia related to coalescent theory, palaeoecology, ancient DNA and synthetic studies of arctic host-parasite assemblages highlighting their cryptic diversity, biogeography and response to climate variation.

Allopatric resistance to I. pepperi was examined in Vaccinium darrowi Camp, which evolved in the absence of I. pepperi in the Southeastern U.S. V corymbosum cv. "Elliott", was used as a susceptible control. Between population variability in I pepperi resistance was assessed by measuring length of the prereproductive period, fecundity, and survivorship on 14 F. darrowi accessions representing 11 discrete wild populations. Length of I. pepperi's prereproductive period and survivorship were not significantly affected. However, differences were detected in fecundity and the intrinsic rate of increase (r(m)). Within population variability in resistance was measured by confining first instars to 24 accessions from a single wild population of V darrowi (NJ88-06). Significant differences in the mean total number of aphids occurring after 20 d were only detected between 2 of the 24 V darrowi accessions. A greater degree of diversity in I. pepperi resistance exists between populations of V darrowi compared to within a population. Constitutive leaf and stem polyphenolics were identified by HPLC-MS and quantified from 14 of the V darrowi accessions. The accessions varied in concentrations of five phenolic acids and seven flavonol glycosides, but a correlation was not found between individual or total phenolics and aphid performance. Overall, screening within and between populations of V darrowi identified promising sources of aphid resistance, but phenolic acid and flavonol glycoside profiles did not predict resistance levels. The mechanism of resistance remains to be identified. C1 Rutgers State Univ, Philip E Marucci Ctr Blueberry & Cranberry Res &, Chatswood, NJ 08019 USA.

In its native range, the BMSB is reportedly attracted to methyl (E,E,Z)-2,4,6-decatrienoate, the male-produced pheromone of another pentatomid common in eastern Asia, Plautia stali Scott. In North America, Thyanta spp. are the only pentatomids known to produce methyl 2,4,6-decatrienoate [the (E,Z,Z)isomer] as part of their pheromones. Methyl 2,4,6-decattienoates were field-tested in Maryland to monitor the spread of the BMSB and to explore the possibility that Thyanta spp. are an alternate host for parasitic tachinid flies that use stink bug pheromones as host-finding kairomones. Here we report the first captures of adult and nymph BMSBs in traps baited with methyl (E,E,Z)-2,4,6-decatricnoate in central Maryland and present data verifying that the tachinid, Euclytia flava (Townsend), exploits methyl (E,Z,Z)-2,4,6-decatrienoate as a kairomone. We also report the unexpected finding that various isomers of methyl 2,4,6-decatrienoate attract Acrosternum hilare (Say), although this bug apparently does not produce methyl decatrienoates. Other stink bugs and tachinids native to North America were also attracted to methyl 2,4,6-decatrienoates. These data indicate there are Heteroptera in North America in addition to Thyanta spp. that probably use methyl 2,4,6-decatrierroates as pheromones. The evidence that some pentatomids exploit the pheromones of other true bugs as kairomones to find food or to congregate as a passive defense against tachinid parasitism is discussed.

Many investigations have lead to use of antiattractants for the management of these pests and have been especially focused on verbenone. However, recent studies have identified new antiattractants for several species of bark beetles. We report results of recent investigations of the response of western pine beetle, Dendroctonus brevicomis LeConte, to two recently identified antiattractants, acetophenone, and fenchyl alcohol, with verbenone as a standard of comparison, in northern California. Release of both acetophenone and verbenone resulted in significantly lower trap catches of D. brevicomis in aggregation pheromone-baited traps, while fenchyl alcohol was inactive. Acetophenone was the only antiattractant that did not reduce numbers of the most abundant predator of D. brevicomis, Temnochila chlorodia (Mannerheim), responding to the attractant pheromone of its prey. Aggregation pheromone-baited traps with acetophenone also had the highest predator/prey ratio. Our results suggest that acetophenone may be part of the intra- and interspecific interactions among sympatric species of bark beetles and may have application in their control.

TI Impacts of dystocia on health and survival of dairy calves SO JOURNAL OF DAIRY SCIENCE LA English DT Article DE dairy calf; dystocia; morbidity; stillbirth ID UNITED-STATES; HOLSTEIN CATTLE; CALVING EASE; CALF; STILLBIRTH; DIFFICULTY; MORTALITY; WEIGHT AB The objectives of this study were to determine incidence of stillbirths and heifer- calf morbidity and mortality, and their association with dystocia on 3 Colorado dairies. A total of 7,380 calvings produced 7,788 calves on 3 Colorado dairy operations between October 1, 2001, and November 5, 2002. Dystocia score and calf status (alive vs. dead) were recorded at calving. Calves that were born alive, but died before 24 h of age, also were recorded as stillborn. Heifer calves were monitored for 120 d to evaluate morbidity and mortality. More than half (51.2%) of calves born to primiparous dams, compared with 29.4% of calves born to multiparous dams, required assistance during calving. A larger percentage of bull calves (40.0%) required assistance compared with heifer calves (33.0%). Proportion of stillborn calves was 8.2% overall, with bull calves, twin calves, calves born to primiparous dams, and those born to dams having dystocia having a larger stillbirth percentage compared with heifer calves, singletons, calves born to multiparous dams, and unassisted calvings, respectively. Multiple logistic regression models were constructed to evaluate stillbirths and heifer health while accounting for the clustering of calves within dairy. The models included dystocia score, parity, and season of calving as explanatory variables for heifer events and also calf gender, and single or twin birth for the stillbirth models. Heifer calves born to dams having severe dystocia had greater odds of stillbirth [odds ratio (OR) = 20.7] and treatment of respiratory disease (OR = 1.7), digestive disease (OR = 1.3), and overall heifer mortality (OR = 6.7). Calf gender and dam parity interacted with calving ease to affect stillbirths. For calves having severe dystocia, heifer calves and calves born to multiparous dams were at increased risk of stillbirth compared with bull calves and calves born to primiparous dams, respectively. Survival analysis demonstrated that severe dystocia was associated with stillbirths and deaths up to 30 d of age. Relatively simple interventions have the potential to significantly reduce the impact of dystocia on calf mortality and morbidity on dairy farms. Education of farm management and personnel in strategies to reduce dystocia and its effect on calf health should be a priority according to the results of this study.

TI Effect of direct-fed microbials on performance, diet digestibility, and rumen characteristics of Holstein dairy cows SO JOURNAL OF DAIRY SCIENCE LA English DT Article DE direct-fed microbial; dairy cow; midlactation ID RUMINAL DIGESTION; SUPPLEMENTATION; CATTLE; PH; FERMENTATION AB The objective of this study was to determine the effect of feeding direct- fed microbial (DFM) products containing Lactobacillus acidophilus and Propionibacteria freudenreichii on the performance, nutrient digestibility, and rumen fermentation of Holstein dairy cows in midlactation. Experiments were conducted from February to May 2003. Cows were fed 1 of 3 dietary treatments: 1) 1 x 10(9) colony-forming units (cfu)/d of live L. acidophilus strain LA747 and 2 x 10(9) cfu/d of live P. freudenreichii strain PF24 (DFM1); 2) 1 x 10(9) cfu/d of live L. acidophilus strain LA747, 2 x 10(9) cfu/d of live P. freudenreichii strain PF24, and 5 x 10(8) cfu/d of L. acidophilus strain LA45 ( DFM2); or 3) lactose (control). Treatments were administered by mixing 45 g of finely ground corn with 5 g of DFM products or lactose and top dressing on the total mixed rations once daily. All cows received the same total mixed ration: 12.7% alfalfa hay, 46.2% corn silage, and 41.1% concentrate on a dry matter (DM) basis. In study 1 (lactation study), 39 multiparous and 18 primiparous Holstein cows were blocked by parity and randomly assigned to treatments for 84 d. Starting on d 35, fecal grab samples were collected from each cow at 5- to 8h intervals over 48 h for digestibility measurements. A rumen fermentation study (study 2) was conducted concurrently with the lactation study. Three rumen-fistulated, multiparous Holstein cows were randomly assigned to dietary treatments DFM1, DFM2, and control in a 3 x 3 Latin square design with 28-d periods. In study 1, there was no difference in average DM intake (23.9, 23.6, and 24.2 kg/d) or 4% fat-corrected milk (36.8, 35.3, and 36.2 kg/d) for treatments DFM1, DFM2, and control. Percentage or yield of milk components also did not differ among treatments. Feed efficiency averaged 1.52 kg of 4% fat-corrected milk/kg of DM intake and did not differ among treatments. There were no differences in apparent DM, crude protein, neutral detergent fiber, or starch digestibility among treatments. In study 2, there was no difference in rumen pH and concentrations of ammonia or total volatile fatty acids measured at 0, 1, 3, and 6 h after feeding. Under the conditions of these studies, supplementing midlactation cows with DFM products containing L. acidophilus and P. freudenreichii did not affect cow performance, diet digestibility, or rumen fermentation.

All diets contained (% of DM) 21% alfalfa silage and 35% corn silage plus 1) 2% urea plus 41% high-moisture shelled corn (HMSC), 2) 12% SSBM plus 31% HMSC, 3) 14% CSM plus 29% HMSC, or 4) 16% CM plus 27% HMSC. Crude protein was equal across diets, averaging 16.6%. Intake and production were substantially reduced, and milk urea, blood urea, and ruminal ammonia were increased on urea vs. the diets supplemented with true protein. Although intake was lower in cows fed SSBM compared with CM, no differences were observed for milk yield among SSBM, CSM, and CM. Yields of fat and protein both were lower on CSM than on CM, whereas SSBM was intermediate. Milk urea and milk protein contents also decreased when CSM replaced SSBM or CM. Diet did not affect ruminal volatile fatty acids except that isobutyrate concentration was lowest on urea, intermediate on CSM, and greatest on SSBM and CM. Urinary excretion of urea N and total N was greatest on urea, intermediate on SSBM and CM, and lowest on CSM. Apparent N efficiency (milk N/N intake) was lower on the CSM diet than on the SSBM diet. Overall, production and N utilization were compromised when the diets of high-yielding dairy cows were supplemented with urea rather than true protein and the value of the true proteins, from most to least effective, was in the order CM > SSBM > CSM.

All diets contained (% of dry matter) 21% alfalfa silage and 35% corn silage plus 1) 2% urea plus 41% high-moisture shelled corn (HMSC), 2) 12% SSBM plus 31% HMSC, 3) 14% CSM plus 29% HMSC, or 4) 16% CM plus 27% HMSC. Crude protein was equal across diets, averaging 16.6%. The CSM diet supplied the least rumen-degraded protein and the most rumen-undegraded protein. Microbial nonammonia N flow was similar among the true protein supplements but was 14% lower in cows fed urea. In vivo ruminal passage rate, degradation rate, and estimated escape for the 3 true proteins were, respectively, 0.044/h, 0.105/h, and 29% for SSBM; 0.051/h, 0.050/h, and 51% for CSM; and 0.039/h, 0.081/h, and 34% for CM. This indicated that CSM protein was less degraded because of both a faster passage rate and slower degradation rate. Omasal flow of individual AA, branched-chain AA, essential AA, nonessential AA, and total AA all were lower in cows fed urea compared with one of the true protein supplements. Among the 3 diets supplemented with true protein, omasal flow of Arg was greatest on CSM, and omasal flow of His was greatest on CSM, intermediate on CM, and lowest on SSBM. Lower flows of AA and microbial nonammonia N explained lower yields of milk yield and milk components observed on the urea diet in the companion lactation trial. These results clearly showed that supplementation with true protein was necessary to obtain sufficient microbial protein and rumen-undegraded protein to meet the metabolizable AA requirements of high-producing dairy cows.

Soluble AA in omasal digesta were fractionated by ultrafiltration into soluble proteins greater than 10 kDa (10K), oligopeptides between 3 and 10 kDa (3-10K), peptides smaller than 3 kDa (small peptides), and free AA (FAA). Omasal flow of total soluble AA ranged from 254 to 377 g/d and accounted for 9.2 to 15.9% of total AA flow. Averaged across diets, flows of AA in 10K, 3-10K, small peptides, and FAA were 29, 217, 50, and 5 g/d, respectively, and accounted for 10.3, 71.0, 17.5, and 1.6% of the total soluble AA flow. Cows with diets supplemented with solvent soybean meal had higher flows of Met, Val, and total AA associated with small peptides than those whose diets were supplemented with XSBM, whereas supplementation with corn gluten meal resulted in higher total small peptide-AA flows than did XSBM. Averaged across diets, 27, 75, and 93% of soluble AA in 10K, 3-10K, and peptides plus FAA flowing out of the rumen were of dietary origin. On average, 10% of the total AA flow from the rumen was soluble AA from dietary origin, indicating a substantial escape of dietary soluble N from ruminal degradation. Omasal concentrations and flows of soluble small peptides isolated by ultrafiltration were substantially smaller than most published ruminal small peptide concentrations and outflows measured in acid-deproteinized supernatants of digesta.

TI A comparison of sampling sites, digesta and microbial markers, and microbial references for assessing the postruminal supply of nutrients in dairy cows SO JOURNAL OF DAIRY SCIENCE LA English DT Article DE dairy cow; nutrient flow; omasum; duodenum ID PROTEIN FLOW; PURINE-BASES; OMASAL FLOW; RUMEN; SHEEP; NITROGEN; BACTERIA; CATTLE; DEGRADABILITY; DIETS AB This study evaluated the impact of some methodological factors on the flows of nutrients at the omasal canal and duodenum of dairy cows fed corn-based diets. Three ruminally and duodenally cannulated cows were assigned to an incomplete 4 x 4 Latin square with four 14-d periods and fed diets formulated to contain different amounts and ruminal degradabilities of crude protein. Samples from the omasal canal and duodenum were obtained and processed according to methodologies routinely used in our laboratories and elsewhere. Methodological factors that were evaluated included microbial references and markers, digesta markers, and sampling sites ( techniques). Considerable variation was found for the compositions of microbial references and their impact on the intestinal supply of microbial nonammonia nitrogen. Likewise, it appears that variation in measuring the ruminal outflow of nitrogen fractions of microbial and dietary origin could be reduced by using (15)N rather than purines as microbial markers. Sampling from the omasum and duodenum resulted in differences for ruminal outflow and site of digestion as well as digestibility of some nutrients, particularly nitrogen fractions and starch. A sizable portion of this variation was associated with deviations from the assumed ideal behavior of digesta markers and collection of samples that were unrepresentative of true digesta. Collectively, outcomes from this study indicate that more research will be required to determine the accuracy of nutrient flows and the agreement between measurements at the omasal canal and duodenum when dairy cows are fed a variety of diets under different feeding systems. Therefore, caution is recommended when extrapolating or interpreting the underlying biology of published results as well as the results of their application (e.g., model parameters and predictions).

TI Temperature-humidity indices as indicators of milk production losses due to heat stress SO JOURNAL OF DAIRY SCIENCE LA English DT Article DE temperature-humidity index; heat stress; milk loss ID DAIRY-CATTLE; GENETIC COMPONENT; HOLSTEIN COWS; CLIMATE; DRY; SYSTEMS AB Meteorological data (1993 to 2004) from 2 public weather stations in Phoenix, Arizona, and Athens, Georgia, were analyzed with test day milk yield data from herds near weather stations to identify the most appropriate temperature-humidity index (THI) to measure losses in milk production due to heat stress in the semiarid climate of Arizona and the humid climate of Georgia. Seven THI with different weightings of dry bulb temperature and humidity were compared. Test-day data were analyzed using 2 models to determine threshold of heat stress and rate of decline of milk production associated with a specific THI. Differences in thresholds of heat stress were found among indices and between regions. Indices with higher weights on humidity were best in the humid climate, whereas indices with larger weights on temperature were the best indicators of heat stress in the semiarid climate. Humidity was the limiting factor of heat stress in humid climates, whereas dry bulb temperature was the limiting factor of heat stress in dry climates.

TI Dry period length in US jerseys: Characterization and effects on performance SO JOURNAL OF DAIRY SCIENCE LA English DT Article DE days dry; Jersey; fertility; somatic cell score ID HOLSTEIN MILK-PRODUCTION; DAIRY-COWS; SUBSEQUENT LACTATION; FEED-INTAKE; PROTEIN; YIELD; FAT AB The objectives of this research were to characterize dry period lengths for US Jerseys, determine the effects of days dry (DD) on subsequent lactation actual milk, fat, and protein yields, fat and protein percentages, somatic cell score (SCS), and days open (DO), and to determine the dry period length that maximizes yield across lactations. Field data, collected through the Dairy Herd Improvement Association, on US Jersey cows first calving between January 1997 and November 2004 were used. Characterization of DD included a frequency distribution of dry period lengths as well as factors affecting US Jersey DD. Of the factors considered in this research, the primary ones affecting dry period length were DO, milk yield, and SCS. Cows with longer DO, lower milk yield, and higher SCS received longer dry periods. The model for analyses included herd-year of calving, year-state-month of calving, parity of calving, previous lactation record, age at calving, and DD as a categorical variable; records were preadjusted for cow effects. A total of 123,032 records from 73,797 cows in 808 herds were used for estimation of DD effects on subsequent lactation actual milk yield. Jersey milk, fat, and protein yields in the subsequent lactation were maximized with 61 to 65 DD. Dry periods of 30 d or fewer resulted in large reductions in subsequent lactation production. A short dry period was beneficial for fat and protein percentages in the subsequent lactation. Short dry periods also resulted in fewer DO in the subsequent lactation; however, this was entirely due to the lower milk yield associated with shortened dry periods. The biggest difference between Jerseys and Holsteins was a much larger detrimental effect on SCS in Jerseys for dry periods of 30 d or less. Jersey SCS increased 10%, relative to the overall mean, for dry periods of 20 d or less and 4.6% for DD between 21 and 30 d. Dry periods of 45 to 70 d maximized yields across adjacent lactations. A dry period length, after first lactation, of 45 to 70 d also maximized actual milk yield across lactations 1, 2, and 3. The final recommendation to Jersey producers is to avoid dry periods of < 45 d. Long dry periods (> 70 d) should also be avoided because these are even more costly to total yield than dry periods < 30 d.

Nonhost status can be an effective measure used to achieve quarantine security. As with quarantine treatments, nonhost status can stand alone as a measure if there is high efficacy and statistical confidence. The numbers of insects or fruit tested during investigation of nonhost status will determine the level of statistical confidence. If the level of confidence of nonhost status is not high, then additional measures may be required to achieve quarantine security as part of a systems approach. Certain countries require that either 99.99 or 99.9968% mortality, as a measure of efficacy, at the 95% confidence level, be achieved by a quarantine treatment to meet quarantine security. This article outlines how the level of confidence in nonbost status can be quantified so that its equivalency to traditional quarantine treatments may be demonstrated. Incorporating sample size and confidence levels into host status testing protocols along with efficacy will lead to greater consistency by regulatory decision-makers in interpreting results and, therefore, to more technically sound decisions on host status.

TI Flight activity of USDA-ARS Russian honey bees (Hymenoptera : apidae) during pollination of lowbush blueberries in Maine SO JOURNAL OF ECONOMIC ENTOMOLOGY LA English DT Article DE Apis mellifiera; Vaccinium angustifolium; pollination; foraging behavior ID HIVE ENTRANCE; TEMPERATURE AB Flight activity was compared in colonies of Russian honey bees, Apis mellifera L. (Hymenoptera: Apidae), and Italian bees during commercial pollination of lowbush blueberries (principally Vaccinium angustifolium Aiton) in Washington Co., ME, in late May and early June in 2003 and 2004. Colonies of the two stocks were managed equally in Louisiana during autumn through early spring preceding observations in late spring each year. Resulting average populations of adult bees and of brood were similar in colonies of the two bee stocks during pollination. Flight during pollination was monitored hourly on 6 d each year by counting bees exiting each colony per minute; counts were made manually with flight cones on 17 colonies per stock in 2003 and electronically with ApiSCAN-Plus counters on 20 colonies per stock in 2004. Analysis of variance showed that temperature, colony size (population of adult bees or brood), and the interaction of these effects were the strongest regulators of flight activity in both years. Russian and Italian bees had similar flight activity at any given colony size, temperature, or time of day. Flight increased linearly with rising temperatures and larger colony sizes. Larger colonies, however, were more responsive than smaller colonies across the range of temperatures measured. In 2003, flight responses to varying temperatures were less in the afternoon and evening (1500-1959 hours) than they were earlier in the day. Russian colonies had flight activity that was suitable for late spring pollination of lowbush blueberries. C1 USDA ARS, Honey Bee Breeding Genet & Physiol Res Lab, Baton Rouge, LA 70820 USA.

Unfortunately, the mass-rearing procedures inherent to the SIT often lead to a reduction in the mating ability of the released males. One potential solution involves the prerelease exposure of males to particular attractants. In particular, exposure of male Mediterranean fruit flies to ginger, Zingiber officinale Roscoe, root oil (GRO) has been shown to increase mating success in laboratory and field cage trials. Here, we describe a field experiment that compares the level of egg sterility observed in two Hawaiian coffee, Coffea arabica L., plots, with GRO-exposed, sterile males released in one (treated) plot and nonexposed, sterile males released in the other (control) plot. Once per week in both plots over a 13-wk period, sterile males were released, trap captures were scored to estimate relative abundance of sterile and wild males, and coffee berries were collected and dissected in the laboratory to estimate the incidence of unhatched (sterile) eggs. Data on wild fly abundance and the natural rate of egg batch also were collected in a remote area that received no sterile males. Despite that sterile:wild male ratios were significantly lower in the treated plot than in the control plot, the incidence of sterile eggs was significantly higher in the treated plot than in the control plot. Correspondingly, significantly higher values of Fried's competitiveness index (C) were found, on average, for treated than control sterile males. This study is the first to identify an association between the GRO "status" of sterile males and the incidence of egg sterility in the field and suggests that prerelease, GRO exposure may represent a simple and inexpensive means to increase the effectiveness of Mediterranean fruit fly SIT programs.

To meet the needs of growers, green lacewings; are being mass-reared commercially around the world. A common salt shaker has been used regularly to distribute eggs into Verticel lacewing larval rearing units. This technique is time consuming and inefficient because the number of eggs distributed in each cell is inconsistent. The multiple orifice distribution (MOD) system described here greatly improved egg distribution efficiency by increasing the percentage of Verticel cells containing the desired one to four eggs per cell (i.e., 40.8 and 52.1% by using salt shaker method versus 61.9% by using the MOD system). This mechanical system significantly reduced the labor and time involved in the process and would cost under $3,500. In addition, this new system could be modified for distribution of other insect eggs. C1 Mississippi State Univ, Dept Entomol & Plant Pathol, Mississippi State, MS 39762 USA.

Trees were harvested as 45- and 60-cm-diameter B&B and immersed in chlorpyrifos at U.S. Domestic Japanese Beetle Harmonization Plan rate (0.24 kg active ingredient [AI]/100 liters) or lower rates of 0.015, 0.03, 0.06, and 0.12 kg (AI)/100 liters. The 0.03, 0.06, and 0.24 kg (AI) rates provided 100% control of Japanese beetle grubs in both 45- and 60-cm B&B. The 0.015 and 0.12 kg (AI) chlorpyrifos rates were 100% effective in three tests. However, in another test, 0.015 and 0.12 kg (AI) chlorpyrifos treatments had four (93% control) and one (98% control) grubs recovered, respectively. Root ball soils consisted of loam, silt loam, or clay loam texture classifications. Trunk diameter and internode growth of red maple harvested as 45-cm B&B decreased linearly with increasing chlorpyrifos dip rate during the first year, but effects were unapparent in the second year. Chlorpyrifos rates had no measurable impact on growth of red maples harvested as 60-cm B&B. No visual phytotoxicity symptoms were detected for chlorpyrifos rate or root ball size treatments. In conclusion, results support lowering the U.S. Domestic Japanese Beetle Harmonization Plan chlorpyrifos dip rate for category 2 states to at least 0.03 kg (AI) for B&B diameters :560 cm. Chlorpyrifos rates < 0.24 kg (AI) will lower cost, reduce worker exposure, and lessen potential environmental contamination.

Effects of various concentrations of wheat germ oil at 0.04,0.07,0.15,0.30, and 0.66% and their possible mode of action were evaluated. Results suggest that addition of wheat germ oil does Dot affect pupal weight, larval developmental period, adult emergence, mating ability, or peak time for egg production. But there was a significant increase in pupal recovery, percentage of adult fliers, egg production, or egg hatch for larvae fed the diet with wheat germ oil compared with those reared on the liquid diet without wheat germ oil. The increase in egg hatch and fliers was dose dependent. Therefore, addition of wheat germ oil to fruit fly rearing diet is a novel way to improve fruit fly quality, especially in egg hatch, fliers, egg production, and pupal recovery.

These baits included the synthetic aggregation pheromone, grandisoic acid (GA) alone, a six-component synthetic host plant volatile combination (6-Tree) identified from foliar and woody tissues of a Stanley plum tree in combination with GA (6-Tree+GA), and the synthetic fruit volatile benzaldehyde (BEN) in combination with GA (BEN+GA). In 2005, the average daily temperature was below 13 degrees C, much cooler than in 2003 and 2004. We hypothesized that plum curculio could not discriminate between baited and unbaited traps because of reduced release rates of odor-bait stimuli due to their temperature-driven release system. From data collected from 2003 to 2005, we found that plum curculio captures in traps baited with GA alone, 6-Tree+GA, and BEN+GA were significantly related to temperature. We created a predictive model to determine the level of activity, i.e., trap captures in baited traps compared with unbaited traps, we would expect to observe at a particular temperature for these same odor stimuli. Our models predicts that at temperatures between approximate to 11 to 13 degrees C we would expect to see no difference between captures in baited and unbaited traps. For captures in odor-baited traps to reach twice those in unbaited traps, our model predicts that temperatures must reach 19.2 degrees C for CA alone, 18.5 degrees C for 6-Tree+GA, and 15.8 degrees C for BEN+GA.

This feeding attractant is dispensed from polypropylene bottles that provide controlled release for several weeks. A killing station was tested in the laboratory, in a screenhouse, and in the field in combination with this lure as an "attract-and-kill" system. Starved alfalfa looper adults (moths) were strongly attracted to the attract-and-kill station in a flight tunnel, and 90.9% of female moths and 87.6% of male moths that contacted the station died. in commercial fields of alfalfa hay, female moths captured in monitoring traps were reduced by 80-93% in plots receiving 125 attract-and-kill stations per hectare. In screenhouse trials using two attract-and-kill stations per screenhouse, oviposition on potted lettuce plants by starved female alfalfa looper moths was reduced by 98.5%. Moths were less likely to be attracted to lures when provided sugar before flight tunnel assays, and oviposition by fed moths was much less affected by attract-and-kill stations in screenhouse trials, compared with starved moths. This method has potential as a means to manage alfalfa looper populations in vegetable and other agricultural crops. However, consideration must be given to competing food and odor sources in the field. C1 USDA ARS, Wapato, WA 98951 USA.

Hazard rating schemes have been developed for D. frontalis, but for these schemes to be accurate and effective, they require extensive on-site measurements of stand attributes such as host density, age, and basal area. We developed a stand bazard-rating scheme for several watersheds in the Ouachita Highlands of Arkansas based upon remotely sensed data and a geographic information system. A hazard model was developed using stand attributes (tree species, stand age and density, pine basal area, and landform information) and was used to establish baseline hazard maps for the watersheds. Landsat 7 ETM+ data were used for developing new hazard maps. Two dates of Landsat imagery were used in the analyses (August 1999 and October 1999). The highest correlations between hazard rating scores and remotely sensed variables from either of the dates included individual Landsat 7 ETM+ bands in the near- and mid-infrared regions as well as variables derived from various bands (i.e., Tasseled cap parameters, principal component parameters, and vegetation indices such as the calculated simple ratio and normalized difference vegetation index). Best subset regression analyses produced models to predict stand hazard to southern pine beetle that consisted of similar variables that resembled but were more detailed than maps produced using inverse distance weighted techniques. Although the models are specific for the study area, with modifications, they should be transferable to geographically similar areas. C1 Univ Idaho, Dept Forest Resources, Moscow, ID 83844 USA.

Although identification of its sex pheromone in 2004 improved monitoring capabilities tremendously, the effectiveness and efficiency of different pheromone trap designs for capturing males has not been evaluated. We deployed green Delta, Pherocon IIB, Pherocon V, Jackson, and Storgard Thinline traps in Homestead, FL, and compared the number of male M. hirsutus captured per trap, the number captured per unit of trapping surface area, the amount of extraneous material captured, and the time taken to count trapped mealybugs. Pheromone-baited traps with larger trapping surfaces (green Delta, Pherocon UB, and Pberocon V) captured more males per trap than those with smaller surfaces (Jackson and Storgard Thinline), and fewest males were captured by Storgard Thinline traps. However, Jackson traps captured as many or more males per square centimeter of trapping surface as those with larger surfaces, and the time required to count males in Jackson traps was significantly less than in green Delta, Pberocon IIB, and Pherocon V traps. Although all trap designs accumulated some debris and nontarget insects, it was rated as light to moderate for all designs. Based on our measures of effectiveness and efficiency, the Jackson trap is most suitable for monitoring M. hirsutus populations. Additionally, unlike the other traps evaluated, which must be replaced entirely or inspected in the field and then redeployed, only the sticky liners of Jackson traps require replacement, enhancing the efficiency of trap servicing.

Oriental fruit moth larvae developed faster on peach than on apple, both on fruit as well as on growing terminal shoots. On fruit, these differences were shown to cause significant changes in both the rate (approximate to 20-60 degree-days earlier emergence on peach than on apple) and patterns of adult emergence among several cultivars of peaches and apples. Slopes of female emergence plots varied by host in 2003, with emergence occurring over a longer period on peach cultivars than on apple cultivars (with one exception). Slopes of male emergence curves did not differ by cultivar in 2003. These host-driven effects could impact the efficacy of traditional pest management approaches and probably complicate efforts to predictively model G. molesta populations in mixed cultivar orchards. Such developmental effects may help to explain previously observed differences in patterns of pheromone trap captures in peach versus apple orchards. Host-associated effects should be incorporated into future models to develop more realistic predictive tools and thus improve integrated pest management efforts.

TI Development of bait stations for fruit fly population suppression SO JOURNAL OF ECONOMIC ENTOMOLOGY LA English DT Article DE Anastrepha ludens; Mexican fruit fly; GF-120; solbait ID SYNTHETIC ATTRACTANT; TEPHRITIDAE; DIPTERA; TRAP AB The application of insecticides is an essential component for eradication or management of fruit fly pests. Impact on nontarget organisms and public rejection of areawide pesticide applications have been major concerns in managing these programs. Bait stations have been proposed as alternative treatments in areas where broadcast insecticides are not acceptable. In this study, we defined bait stations as discrete containers of attractants and toxins, which are targeted at specific pests. Tests were carried out using the Mexican fruit fly, Anastrepha ludens (Loew), as the experimental insect. Our first bait station design was a sheet of sponge material fastened to a plastic peaked cover. Liquid bait consisting of protein hydrolyzate, sugar, adjuvants, a photoactive dye toxicant, and other additives was applied to the sponge. This station, when tested in an orchard, reduced sterile released adult populations by 70-90% in 4 d compared with check plots. Other tests in field cages showed that the bait station was approximate to 22% less effective in killing adults compared with spot sprays on trees. We formulated a gelled bait by using a more refined hydrolyzed protein, supplemental attractants, feeding stimulants, and additives to protect the bait from drying. A series of experiments were carried out in field cages by using a cylindrical bait station that provided improved protection of the bait. These tests showed that there is a gradual decline in bait effectiveness with age. C1 USDA ARS, Crop Qual & Fruit Insect Res Unit, Weslaco, TX 78596 USA.

TI FLYBRELLA: A device to attract and kill house flies SO JOURNAL OF ECONOMIC ENTOMOLOGY LA English DT Article DE house fly; trap; bait; attractant; toxicant ID MUSCIDAE; DIPTERA; PHEROMONE; FLY AB FLYBRELLA is a lightweight inexpensive trap that can be suspended like an upside-down umbrella in prominent locations where house flies, Musca domestica L., rest. It consists of a solid, cylindrical backbone to which is attached a perforated transparent tube, or baffle, with a commercial sugar/toxicant strip affixed inside. Centered directly beneath the tube and also attached to the backbone is a 10-cm-diarneter inverted opaque plastic cone. House flies readily enter the tube, feed on the fast-acting toxicant, and then fall directly down the tube where they are collected in and concealed by the cone. The cone may be emptied easily through a capped opening in the bottom. In paired indoor tests, the efficacy of the commercial sugar/toxicant strip was increased significantly by the individual addition of several other attractant materials. Variants of the original design were tested, including a more efficient design featuring two concentric tubes with offset perforations. The toxicant strip may be easily removed and/or replaced when desired. C1 USDA ARS, CMAVE, Gainesville, FL 32604 USA.

Four primary test sites (Arizona and Florida, Mississippi, and South Carolina [hereafter southeast]) have been used for this purpose. Various parameters of termite attack at water-only control plots were examined in this study to assess the relative pressures of termites at each site. Termiticide studies installed between 1971 and 2001 by using ground board (GB) and concrete slab (CS) test methods were included. GB control plots were attacked 85% of the time in the southeast, about twice the rate observed in Arizona (43%). CS plots were attacked 59-70% of the time in the southeast, significantly higher than in Arizona (43%). Termites were slower to initiate attack at control plots in Arizona compared with the southeast, and they were up to twice as slow at GB controls. Once initial attack began, GB plots were reattacked at higher percentages in the southeast (89-90%) than in Arizona (67%). Reattack at CS plots ranged from 65% in Arizona and South Carolina to 76% in Mississippi. Termites caused less damage to wooden blocks in control plots in Arizona than the southeast. Attack rates at controls generally declined during the 1990s, but these rates have rebounded since 2000, except at CS plots in Arizona and South Carolina. Statistical analysis of attacks at plots treated with chlorpyrifos, cypermethrin, fenvalerate, and permethrin also was undertaken. Time to initial termite attack (failure) of the organophosphate chlorpyrifos was generally shorter in Arizona than in the southeast, whereas time to initial attack in plots treated with one of three pyrethroids (cypermethrin, fenvalerate, and permethrin) was generally longer in Arizona.

Three insect management tactics (Bt corn, its nontransgenic isoline, and isoline plus tefluthrin) were evaluated with two weed species (giant foxtail, Setaria faberi Herrm, and large crabgrass, Digitaria sanquinalis L. Scop), and four weed management regimes (weed free, no weed management, early [V3-4] weed management and late [V5-6] weed management) in a factorial arrangement of a randomized split split-plot design. In each case, the isoline was also tolerant to glyphosate. Root damage was significantly affected by insect management tactics in both years, but weed species and weed management did not significantly affect damage to Bt corn in either year. Adult emergence was significantly affected by insect management tactics in both years and by weed species in 2003, but weed management and the interaction of all three factors was not significant in either year. The sex ratio of female beetles produced on Bt corn without weeds was generally greater than when weeds were present and this difference was significant for several treatments each year. Average dry weight of male and female beetles emerging from Bt corn was greater than the weights of beetles emerging from isoline or isoline. plus tefluthrin in 2003, but there was no difference for females in 2004 and males weighed significantly less than other treatments in 2004. The implications of these results in insect resistance management are discussed. C1 Univ Missouri, Dept Entomol, Columbia, MO 65211 USA.

Lam. (Convolvulaceae), is limited by several insect pests, including Diabrotica spp. (Coleoptera: Chrysomelidae), and new integrated pest management (IPM) techniques for this crop are needed. Host plant resistance is one attractive approach that fits well into IPM programs. A host plant resistance research program typically depends on reliable bioassay procedures to streamline evaluation of germplasm. Thus, a bioassay technique was developed for evaluating sweetpotato germplasm by using adults of the banded cucumber beetle, Diabrotica balteata LeConte, and spotted cucumber beetle, Diabrotica undecimpunctata howardi Barber. A single beetle was placed on a piece of sweetpotato peel (periderm and cortex with stele removed) that was embedded periderm-side up in plaster in a petri dish. Feeding and longevity of insects on 30 sweetpotato genotypes were evaluated in two experiments by using this procedure. Adult longevity ranged from 7 to 11 d for starved individuals to 211 d for beetles fed a dry artificial diet. Longevity of banded cucumber beetles that fed on sweetpotato peels ranged from 12 d for the most-resistant genotype to 123 d for SC1149-19, a susceptible control cultivar. Longevity of spotted cucumber beetles was slightly shorter than longevity of banded cucumber beetles. For the most resistant sweetpotato genotypes, both Diabrotica species exhibited a significant delay in initiation of feeding, and more beetles died on these genotypes before they had fed. Both antibiosis and nonpreference (antixenosis) are important mechanisms of resistance in sweetpotato genotypes. This bioassay was consistent with field results, indicating that this technique could be useful for evaluating resistance to Diabrotica spp. in sweetpotato genotypes.

However, difficulties in quantifying release rates of ammonia have limited abilities to make comparisons among field tests of different species by using different formulations. Therefore, Fourier transform infrared (FTIR) spectroscopy was evaluated as a method to quantify ammonia from synthetic lures. Analysis of the headspace from commercial ammonium bicarbonate and ammonium acetate lures indicated that there is a large burst of ammonia liberated upon initial exposure of the lures, but after 5-7 d the release rates stabilize and remain steady for at least 60 d under laboratory conditions. During the period of steady release, FTIR static measurements showed an average of 0.12 and 0.21 mu g of ammonia per 50-ml sample from ammonium bicarbonate and ammonium acetate lures, respectively. FTIR dynamic measurements from ammonium acetate lures indicated a steady release rate of approximate to 200 mu g/h. Ammonia release rate from ammonium acetate lures could be reduced by decreasing the surface area of the release membrane, and the presence of crystal formations on the membrane seemed to decrease the longevity of the ammonium acetate lures.

A single shelving unit was used in each trial and a grid of sentinel egg disks was used to evaluate foraging success. The shelving consisted of pallet units with five shelves that were either bare or stocked with empty cereal boxes. In each replicate, approximate to 500 female Dichogramma were released at the center of the shelving unit and allowed to forage for 48 h. Percentage of egg parasitism and percentage of host egg mortality were recorded after 7 d. Foraging success as well as the spatial pattern of parasitism differed significantly among the three Trichogramma species. Percentage of egg parasitism was approximate to 4 times greater for T deion than for T. ostriniae or T pretiosum. The vertical distribution of parasitism by T. deion was also more uniform than for the other two species. In addition, the presence of packaging affected the foraging efficiency of T ostriniae and T pretiosum but not T deion. Based on these findings, Trichogramma deion may be the best-suited candidate for augmentative biological control of P. interpunctella in retail stores, and a central release point of T deion will likely provide adequate coverage of products on pallet-type shelving.

An economic empirical model of heat treatment and chemical applications was developed using minimization of costs at a target risk level associated with the grain-damaging insects Tribolium castaneum (Herbst), Sitophilus oryzae (L.), and Rhyzopertha dominica (F.). Risk was measured as a deviation below a target mortality goal (Target MOTAD). Insect mortality and air temperature during heat treatment were evaluated for empty storage bins with a full drying floor, along with a similar evaluation of insect mortality for two application rates of a contact pyrethroid insecticide, cyfluthrin 20% active ingredient (AI) wettable powder. A high-output propane heater (29 kW) had the lowest cost and risk level of all heating systems and produced 100% mortality in 2 h for the three insect species at all test locations. An electric duct-heater system (18 kW) also produced 100% mortality at all test locations after 40 h, but it had significantly higher costs. The other heating system configurations in the study had significantly higher risk levels of insect mortality, and the electric systems were not cost-effective. Both chemical rates had low costs and risk levels, with high mortality results. C1 USDA ARS, Grain Mkt & Prod Res Ctr, Manhattan, KS 66502 USA.

Wayne TI Field evaluations of potential aggregation inhibitors for the southern pine beetle, Dendroctonus frontalis (Coleoptera : Curculionidae) SO JOURNAL OF ENTOMOLOGICAL SCIENCE LA English DT Article DE southern pine beetle; semiochemical; pheromone; disruption; nonhost volatile; bioinsecticide; antiaggregation ID BARK BEETLES; SCOLYTIDAE; PHEROMONE; VOLATILES; PRODUCTS AB Semiochemicals that inhibit the response of the southern pine beetle, Dendroctonus frontalis Zimmermann, to its aggregation pheromone have been used with varying degrees of success to protect individual trees from attack and to stop infestation growth. However, semiochemical disruptants have not experienced wide use in management of D. frontalis, due in part to the normally prohibitive expense associated with treatments using verbenone and 4-allylanisole, the two EPA-registered semiochemicals for this species. Therefore, we conducted some initial trap-based screenings of candidate compounds with the aim of discovering alternative inhibitory semiochemicals for use in management of D. frontalis. In separate experiments in Mississippi and Georgia, baits containing either 2-phenylethanol or myrtenol significantly reduced attraction of one or both sexes of D. frontalis to traps baited with a standard attractant (i.e., the D. frontalis aggregation pheromone frontalin and the host monoterpene alpha-pinene). In combination, the two compounds caused a 92% decrease in total beetle response to the standard attractant, although this reduction was not significantly greater than that produced by 2-phenylethanol alone. In one test, a blend of nonhost volatiles (1-hexanol, cis-3-hexen-1-ol, hexanal, and nonanal) significantly reduced attraction of male D, frontalis, but these observations were not duplicated in a second test. Another combination of candidate inhibitors (the nonhost blend plus guaiacol and benzaldehyde) also significantly inhibited response of male beetles. At the specific doses used in our tests, we failed to observe reduction in D. frontalis attraction by the following compounds presented singly: benzaldehyde, guaiacol, 3-methylcyclohex-2-en-1-one (3,2-MCH), myrtenal, and verbenone.

This beetle is tropical in origin, but feral populations in the USA are known to persist in southern California and in central and southern Florida. Field populations of D. catalinae are not known to occur in northern Florida, GA, or South Carolina, and there has not been any report of field releases in these areas. A study was conducted to determine the ability of D. catalinae to survive in regions with mild winters where B. tabaci survives year-round, such as coastal South Carolina and northern Florida. Delphastus catalinae was sampled in field cages from December to April in 2002-2004. Only a few individuals were collected at the end of each winter. In the laboratory, at a constant temperature of 15 degrees C, adult survival was up to 9 months (269 d), whereas survival was up to 16 d at 5 degrees C. Without food, adult longevity was decreased by about 90%. A sample of the population from a laboratory test indicated that old females (at least 242 d) produced viable eggs. Eggs held at 5 degrees C did not hatch, whereas 48% of those held at 15 degrees C hatched. Conversely, 98% of eggs held at 25 degrees C hatched. At 15 degrees C, none of the larvae survived to the pupal stage, whereas at 25 degrees C, 86% of the larvae survived to the adult stage. Winter temperatures near freezing may result in excessive D. catalinae mortality and few or no survivals at the end of the winter. These results help define the impact of long-term low temperatures on the northern geographical limit of D. catalinae and will aid in whitefly management decisions regarding this predator.

Results from crosses that involved the females of D. u. howardi and the males of D. u. undecimpunctata had all F-1 progeny with phenotypes as the male parent. Similarly, in all the crosses that involved the females of D. u. undecimpunctata and the males of the D. u. howardi, all the F-1 progeny had phenotypes as the male parent. DNA from females and males were amplified using two primers to confirm the paternity of F-1 progeny. The study on the inheritance of body color in these two subspecies appeared to be governed by one dominant gene (monogenic), and it is the male that determines the body color of progeny in both subspecies.

The presence of what appears to be a spermatophore, and/or the enlargement of the genital pouch and the seminal depository through infusion of fluids from the male was evidence of females having mated. Loss of relative size and white material from the accessory glands of males held from females for 7 d prior to mating was evidence of males having mated. Decreased size of seminal vesicles resulting from insemination was not seen to be an indicator of males having mated. The photographs provide a simple method for determining mating, and when used in conjunction with drawings of tarnished plant bug morphology provided by early authors, may facilitate the understanding of other aspects of tarnished plant bug reproductive morphology.

(bird cherry-oat aphid) and Diuraphis noxia (Mordvilko) (Russian wheat aphid) are common aphid pests of wheat and can cooccur at relatively high levels within wheat fields. Resistance to both aphids has been identified in several triticale accessions. We conducted experiments to identify and characterize antibiosis-type resistance to R. padi in additional triticale lines and to test R. padi-resistance levels in several backcrossed, triticale-derived lines of D. noxia-resistant wheat. Triticale accessions '6A-558', `H85-734' and 'M86-6174' were identified with moderate levels of antibiosis to R. padi. All three accessions limited R. padi population growth relative to 'Arapahoe' over 13 d. 6A-558 increased development time of R. padi compared to that on Arapahoe, and 6A-558, H85-734 and M86-6174 each decreased the number of nymphs produced by R. padi over 7 d. Additional tests confirmed 'N1185' triticale as a strong source of resistance to R. padi, and showed that 'Lamar' wheat was not resistant to R. padi. Tests of wheat lines derived from crosses between N1185 and Lamar and then selected for resistance to D. noxia showed that three of 13 lines reduced the number of R. padi per plant, with resistance levels comparable to N1185 in two lines. Nymphiposition by R. padi measured over a 24-h period did not differ among any lines in no-choice tests. The results provide further support that triticale is a significant source of resistance to R. padi, but further work is needed to understand transference of R. padi-resistance from triticale to wheat.

TI Diel patterns of pheromone production in the boll weevil (Coleoptera : Curculionidae) SO JOURNAL OF ENTOMOLOGICAL SCIENCE LA English DT Article DE boll weevil; Anthonomus grandis; pheromone; diel pattern ID TRAPS; TEXAS; FIELD AB Detailed knowledge of boll weevil, Anthonomus grandis Boheman, chemical ecology on cotton, Gossypium hirsutum L., is needed to improve pheromone trapping methods. Recent studies using headspace collections have indicated that most pheromone is not in the feces as previously assumed. We used headspace collections to examine the diel patterns of boll weevil pheromone production and to determine whether the timing of food replacement influenced those patterns. Pheromone production of individual 9- and 11 -d-old weevils was estimated during 4 daily periods (0730-1130, 1130-1530, 1530-1930, and 1930-0730 h) under temperatures of 27 +/- 2 degrees C and with a 13:11 (L:D) h photoperiod that began at 0700 h. Weevils fed daily at 0730 h produced more pheromone (2.83 +/- 0.25 mu g h(-1)) than weevils fed at 1530 h (1.95 +/- 0.25 mu g h(-1)), and 11-d-old weevils produced more pheromone (2.62 +/- 0.22 mu g h(-1)) than 9-d-old weevils (2.16 +/- 0.23 mu g h(-1)). Furthermore, weevils fed at 0730 h exhibited a clear diel pattern of pheromone production with maximal and minimal production occurring between 1130-1530 h and 1930-0730 h, respectively. Weevils fed at 1530 h exhibited a similar periodicity, but the pattern was less distinct. Pheromone composition of weevils fed at 0730 h was relatively consistent among daily periods and the ratio of the 4 components was approximately 45:42:3:10 (I:II:III:IV). However, pheromone composition varied significantly among daily periods for weevils fed at 1530 h. Our results demonstrate a diel periodicity in pheromone production by the boll weevil, and illustrate the need for careful control of weevil diets in such studies.

Nearly all irradiated and unirradiated bugs flew from Petri dishes fitted with inverted cones. Male mating success of irradiated insects trended lower than that of unirradiated insects in laboratory tests, but was significantly lower than that of unirradiated insects in field cages. Irradiated males released into field cages were more likely than unirradiated males to be captured in nonsticky traps baited with virgin females. Unirradiated females placed in nonsticky traps deployed in weed fields attracted more native tarnished plant bugs than irradiated females.

SO JOURNAL OF FISH DISEASES LA English DT Article DE concurrent infection; Gyrodactylus; immersion; mortality; Nile tilapia; Streptococcus ID INIAE INFECTION; FISH; MORTALITY; MONOGENEA; PARASITES AB Streptococcus iniae and Gyrodactylus niloticus are two common pathogens of cultured Nile tilapia, Oreochromis niloticus. We studied concurrent infection of tilapia by G. niloticus and S. iniae and evaluated whether parasitism in tilapia with Gyrodactylus increased susceptibility and mortality following immersion infection with S. iniae. Results showed that death mainly occurred in fish with G. niloticus and challenged with S. iniae (G-S group). The accumulative mortality (42.2%) was significantly higher in the G-S group than in fish not infected by the parasite (6.7%), but exposed to S. iniae. Bacteriological examination revealed S. iniae from >= 92% of dead or moribund fish challenged with S. iniae. Gyrodactylus not only damaged fish epithelium and provided entry for invasive bacteria but also was found to harbour viable cells of S. iniae for 24 and 72 h. Streptococcus iniae was isolated from 60% and 40% of G. niloticus collected from fish infected by intraperitoneal injection or immersion, respectively, at 24 h post-challenge. The present study confirms that parasitism of tilapia by G. niloticus increased host mortality following exposure to the bacterial pathogen S. iniae.

TI Factors affecting compost tea as a potential source of Escherichia coli and Salmonella on fresh produce SO JOURNAL OF FOOD PROTECTION LA English DT Article ID WATER EXTRACTS; MOLASSES; O157-H7; DISEASE AB Compost tea (CT) is an unheated on-farm infusion of compost used as a spray or soil drench to promote plant growth and control foliar and root diseases. Because food safety involves all aspects from farm to fork, CT should meet basic microbiological criteria for water quality. This report describes the effects of two CT production processes, aerated and nonaerated, on growth and survival of foodborne pathogens and fecal coliforms. Seven commercially available nutrients used to supplement CT were tested individually and in combination for their effects on the growth of Escherichia coli and Salmonella. Compost containing 101 to 103 CFU/g initial concentrations of E. coli O157:H7 and Salmonella Enteritidis were used to assess growth and survival responses to aerated CT (36-h preparations) and nonaerated CT (8.5-day preparations). Pathogen and fecal coliform populations were undetectable by 8.5 days in nonaerated CT without nutrient supplements. E. coli O15TH7 decreased to below detection levels in aerated CT at 36 h without the use of supplements. In contrast, the addition of commercially formulated mixtures or combinations of nutrient supplements resulted in growth of E. coli O157: H7, Salmonella, and fecal coliforms by 1 to 4 log CFU/g in both aerated and nonaerated CT When nutrient supplements were added, aerated CT sustained higher concentrations of E. coli O157:H7, Salmonella, and fecal coliforms than did nonaerated CT Thus, addition of supplements supports growth of human pathogens from very low initial concentrations in both aerated and nonaerated CT and should be avoided when CT is used on fresh produce.

Injected turkey samples containing calcium lactate, potassium lactate, or sodium lactate (1.0, 2.0, 3.0, or 4.8% [w/w]), along with a control (product without lactate), were inoculated with a three-strain cocktail of C. perfringens spores to achieve a final spore population of 2.5 to 3.0 log CFU/g. The inoculated product was heat treated and exponentially cooled from 54.5 to 7.2 degrees C within 21, 18, 15, 12, 9, or 6.5 h. Cooling, of injected turkey (containing no antimicrobials) resulted in C. perfringens germination and an outgrowth of 0.5, 2.4, 3.4, 5.1, 5.8, and 5.8 log CFU/g when exponentially cooled from 54.4 to 7.2 degrees C in 6.5, 12, 15, 18, and 21 h, respectively. The incorporation of antimicrobials (lactates), regardless of the type (Ca, Na, or K salts), inhibited the germination and outgrowth of C. pe fringens spores at all the concentrations evaluated (1.0, 2.0, 3.0, and 4.8%) compared to the injected turkey without acetate (control). Increasing the concentrations of the antimicrobials resulted in a greater inhibition of the spore germination and outgrowth in the products. In general, calcium lactate was more effective in inhibiting the germination and outgrowth of C. petfringens spores at 1.0% concentration than were sodium and potassium lactates. Incorporation of these antimicrobials in cooked, ready-to-eat turkey products can provide additional protection in controlling the germination and outgrowth of C. petfringens spores during cooling (stabilization).

Typically, they have a bitter taste, which increases with maturity, probably because of increased levels of glucosinolates. While glucosinolate degradation products have been isolated from various members of the Brassica family, the effect of variety and maturity on these products has not been determined. This study focused on the glucosinolate degradation products of three varieties of turnip greens: Purple Top, Seven Top and Tokyo Cross, harvested 45, 60 and 75 days after planting. Four volatile components (benzene acetonitrile, benzene propane nitrite, 1H-indole-3-acetonitrile and benzene ethyl isothiocyanate) were isolated, identified and quantified. All increased significantly (P < 0.05) as the greens matured; however, only benzene propane nitrile and 1H-indole-3-acetonitrile were significantly affected (P < 0.05) by variety.

TI Coated lupin bean snacks SO JOURNAL OF FOOD QUALITY LA English DT Article ID ALBUS AB The potential of lupin in human nutrition is generally underestimated worldwide and the development of lupin-based convenient food products needs to be expanded. The objective of this study was to develop savory- and sweet-coated snacks from Lupinus albus grains. Lupin beans were prepared using the traditional Middle Eastern process by cooking, soaking in saltwater peeling, and either roasting or deep-frying. Sensory analysis was performed using a 5-point hedonic scale of four lupin snacks, two savory (Caribbean jerk and fajita) and two sweet (cinnamon and lemon). Overall, sensory attribute scores for the fried savory snacks were better than the roasted, and as expected, the residue on the fingers of panelists after handling the lupin snacks was higher in the fried samples. Higher scores were given to the Caribbean jerk than to the fajita-flavored lupin snacks for aroma, spiciness and salt level. The panelists gave high (much too strong) crispiness scores to the fried lemon and the roasted cinnamon lupin snacks. Sweet-coated lupin snacks (combining roasted and fried) received higher than 50% of just about right scores for color aroma, sugar spiciness and flavor Three different samples of L. albus evaluated by consumer panelists were also processed (fried and roasted) to determine color changes using the CIE 1976 L*, a*, b* Color Space color space. The color was recorded in samples of single beans and groups of beans. The darkness (-L*) of the fried and roasted samples increased 28 and 13%, respectively, compared to the raw lupin beans, with a more homogeneous darkness and color in the roasted sample. Delta E suggests that the general change in color was higher in the roasted samples, especially when measured as a group.

Deacetylated xanthan exhibited a stronger synergistic interaction with guar than native xanthan did due to the destabilized helical structure and increased chain flexibility of the deacetylated xanthan. No gels were observed for all xanthan-guar mixtures. Native xanthan-guar mixtures exhibited liquid-like behavior, whereas deacetylated xanthan-guar mixtures exhibited a gel-like behavior. The relative viscosity and elasticity of deacetylated xanthan-guar mixtures were much stronger than those for native xanthan guar mixtures. The intrinsic viscosities of deacetylated xanthan-guar mixtures were higher than the calculated values assuming no interaction, whereas the intrinsic viscosities of native xanthan-guar mixtures were lower than the calculated values assuming no interaction, demonstrating that inter-molecular binding occurred between the disordered segments of xanthan and guar gum in dilute aqueous solutions.

Cheddar cheese was made weekly using whole milk from Alpine goats and cheeses manufactured at weeks 4, 5, 12, 14, 15, 21, 22, and 23 of lactation were evaluated for proteolytic and rheological properties at 5 d after manufacture and after 8, 16, and 24 wk of aging at 4 degrees C. Rheology results indicated that a minimum of 8 wk of aging was needed to stabilize the texture of the cheese and that the most uniform cheeses were made from mid lactation milk. Cheese manufactured at weeks 12 to 15 of lactation were the firmest, had the least flexible protein matrix (highest values for hardness, chewiness, and shear stress and rigidity at point of fracture), and the lowest degree of proteolysis. Understanding the factors that impact the texture of cheese, such as aging and the period of lactation that cheesemilk is obtained, will help develop guidance for maintaining the production of high quality and uniform caprine milk cheeses.

Within the past 10 years, three normative birch leaf mining sawflies, have been found in Alaska: Fenusa pumila, Heterarthrus nemoratus, and Profenusa thomsoni. Damage, caused primarily by A thomsoni, is particularly notable in urban areas where the impact of browning free crowns in mid-to-late summer raises public concern. The initial outbreak in Anchorage in 1996 increased to more than 32,000 ac by 2003. That same year, a survey was initiated to determine the extent of leaf mining sawflies throughout most of the state. Adult emergence, flight period, and larval phenology were assessed also. Surveys done through 2006 show that P. thomsoni is present over 20% of the surveyed area with the largest contiguous population in south central Alaska and localized populations in the Fairbanks area and on the Kenai Peninsula. The spread of P. thomsoni in Alaska suggests an association between establishment of new infestations, human population centers, and major travel routes.

In examining open reading frames (ORFs), nine differ between vaccine and oncogenic strains. A 177 bp insertion was identified in the overlapping genes encoding the Meq, RLORF6 and 23 kDa proteins of CV1988. Three ORFs are predicted to encode truncated proteins. One, designated 49.1, overlaps the gene encoding the large tegument protein UL36 and encodes a severely truncated protein of 34 aa. The others, ORF5.5/ORF75.91 and ORF3.0/78.0, located in the repeat regions (diploid), encode a previously unidentified ORF of 52 aa and a truncated version of the virus-encoded chemolkine (vIL-8), respectively. Subtle genetic changes were identified in the two ORFs encoding tegument proteins UL36 and UL49. Only one diploid ORF (ORF6.2/ORF75.6) present in the genomes of the three virulent strains is absent in the CVI988-BAC genome. Seventy non-synonymous amino acid substitutions were identified that could differentiate CVI988-BAC from all three oncogenic strains collectively. Estimates of the non-synonymous to synonymous substitution ratio (omega) indicate that CV1988 ORFs are generally under purifying selection (omega < 1), whereas UL39, UL49, UL50, RLORF6 and RLORF7 (Meq) appear to evolve under relaxed selective constraints. No CV1988 ORF was found to be under positive evolutionary selection (omega >> 1). C1 USDA ARS, SE Poultry Res Lab, Athens, GA 30605 USA. Inst Anim Hlth, Compton RG20 7NN, Berks, England.

The flavivirus envelope (E) glycoprotein is the primary antigen inducing protective immunity; however, the presence of cross-reactive antibodies in human sera creates problems for serodiagnosis. Using a West Nile virus-like particle system, we performed mutagenesis across all three E protein functional domains to identify epitope determinants for a panel of monoclonal antibodies (mAbs) raised against different flaviviruses and exhibiting diverse patterns of cross-reactivity. Residues within the highly conserved fusion peptide were the only epitope determinants identified and were important not only for broadly cross-reactive mAbs recognizing all of the medically important flavivirus serocomplexes, but also for less-broad, complex-reactive mAbs. Moreover, different substitutions at specific fusion peptide residues produced highly variable effects on antibody reactivity and virus-like particle secretion. These results support and extend the conclusion that the fusion peptide region constitutes an immunodominant epitope stimulating antibodies with diverse patterns of cross-reactivity.

The goal of this study was to optimize methodologies for detecting M paratuberculosis in manure from an infected dairy cow or in contaminated soil samples using a quantitative, real-time PCR (QRT-PCR) based analysis. Three different nucleic acid extraction techniques, the efficiency of direct versus indirect sample extraction, and sample pooling were assessed. The limit of detection was investigated by adding dilutions of M paratuberculosis to soil. Results show that the highest yield (19.4 +/- 2.3 mu g(-1) DNA extract) and the highest copy number of the targeted M paratuberculosis IS900 sequence (1.3 +/- 10.2 x 10(8) copies g(-1) manure) were obtained with DNA extracted from manure using Qbiogene's Fast (R) DNA Spin kit for soil. Pooling ten samples of M paratuberculosis-contaminated soil improved the limit of detection ten fold (between 20 and 115 M paratuberculosis cells g(-1) soil). Detection was between 65% and 95% higher when samples were extracted directly using beadbeating than when using pre-treatment with cell extraction buffers. The final soil-sampling and extraction regime was applied for detection of M paratuberculosis in pasture soil after the removal of a M paratuberculosis culture positive dairy cow. M paratuberculosis remained in the pasture soil for more than 200 days. Results from these studies suggest that DNA extraction method, sampling protocol and PCR conditions each critically influence the outcome and validity of the QRT-PCR analysis of M paratuberculosis concentrations in environmental samples.

Recent studies have shown that antiinflammatory drugs may suppress microglial activation and thus protect against microglial overactivation and subsequent cell loss. Research also suggests that fruits such as berries may contain both antioxidant and antiinflammatory polyphenols that may be important in this regard. Our previous research showed that blueberry extract was effective in preventing oxidant-induced calcium response deficits in M1 (muscarinic receptor)-transfected COS-7 cells. Extrapolating from these findings, the current study investigated the effect of blueberry extract on preventing inflammation-induced activation of microglia. Results indicated that treatments with blueberry extract inhibited the production of the inflammatory mediator nitric oxide (NO) as well as the cytokines interleukin-1 beta and tumor necrosis factor-alpha, in cell conditioned media from lipopolysaccharide (LPS)-activated BV2 microglia. Also, mRNA and protein levels of inducible nitric oxide synthase and cyclooxygenase-2 in LPS-activated BV2 cells were significantly reduced by treatments with blueberry extract. The results suggest that blueberry polyphenols attenuate inflammatory responses of brain microglia and could be potentially useful in modulation of inflammatory conditions in the CNS.

The aim of this study was to examine whether effects of mild Zn deficiency and subsequent Zn supplementation during pregnancy persist after weaning and affect immune function of the offspring. Adult female rats were fed a Zn-adequate diet (ZC, n = 8) or a Zn-deficient diet VD, n = 8) from preconception through lactation. Pregnant rats were supplemented with either Zn (1.5 mg Zn in water) or placebo (water) 3 times/wk throughout pregnancy. Pups were orally immunized with cholera toxin and bovine serum albumin-dinitrophenol QNP) 3 times at weekly intervals and killed 1 wk after the last dose. Proliferation and cytokine responses in lymphocytes from Payer's patches and spleen, and antigen specific antibodies in serum were studied. Zn supplementation of ZD dams led to enhanced lymphocyte proliferation and IFN-gamma responses in pups ZDZ+. In contrast, Zn supplementation of ZC dams suppressed these responses in pups ZCZ+. Total and DNP-specific IgA responses were lower in pups of the Zn-deficient group compared with the Zn-adequate group. Relative thymus weight was greater in the pups (ZDZ-) of ZD placebo-supplemented darns compared with the other groups at 31 d of age. Prepregnancy and early in utero Zn deficiency affected IgA responses in pups that could not be restored with Zn supplementation during pregnancy, Zn supplementation of ZC dams induced immunosuppressive effects in utero that may also be mediated through milk and persist in the offspring after weaning.

Proteases have been implicated in many of these processes, but the occurrence and functions of serine proteases have not been characterized. Bioinformatic analysis suggests that the Eimeria tenella genome contains several serine proteases that lack homology to trypsin. Using RT-PCR, a gene encoding a subtilisin-like and a rhomboid protease-like serine protease was shown to be developmentally regulated, both being poorly expressed in sporozoites (SZ) and merozoites (MZ). Casein substrate gel electrophoresis of oocyst extracts during sporulation demonstrated bands of proteolytic activity with relative molecular weights (Mr) of 18, 25, and 45 kDa that were eliminated by coincubation with serine protease inhibitors. A protease with Mr of 25 kDa was purified from extracts Of unsporulated oocysts by a combination of affinity and anion exchange chromatography. Extracts of SZ contained only a single hand of inhibitor-sensitive proteolytic activity at 25 kDa, while the pattern of proteases from extracts of MZ was similar to that of oocysts except for the occurrence of it 90 kDa protease, resistant to prootease inhibitors. Excretory-secretory products (ESP) from MZ contained AEBSF (4-[2-Aminoethyl] benzenesuphonyl fluoride)-sensitive protease activity with a specific activity about 10 times greater than that observed in MZ extracts. No protease activity was observed in the ESP from SZ. Pretreatment of SZ with AEBSF significantly reduced SZ invasion and the release of the microneme protein, MIC2. The Current results Suggest that serine proteases are present in all the developmental stages examined.

The present study describes a rapid method for purifying high numbers of C. parvum oocysts from feces of infected calves that contains minimal contaminating fecal material and bacteria. The isolation method is based on differential flotation of C. parvum oocysts in NaCl, followed by ether extraction to solubilize lipids in calf feces.

TI Compression molding of phenolic resin and corn-based DDGS blends SO JOURNAL OF POLYMERS AND THE ENVIRONMENT LA English DT Article DE biofillers; bioplastics; composites; mechanical properties; tensile testing ID BIOCOMPOSITES; LIQUEFACTION; LIGNIN; POWDER; WOOD AB With the rapid growth in the ethanol fuel industry in recent years, considerable research is being devoted to optimizing the use of processing coproducts, such as distillers dried grains with solubles (DDGS), in livestock diets. Because these residues contain high fiber levels, they may be amendable to incorporation into bio-based composites. Thus, the goal of this study was to demonstrate the viability of using corn-based DDGS as a biofiller with phenolic resin, in order to produce a novel biomaterial. DDGS was blended with phenolic resin at 0, 10, 25, 50, 75, and 90%, by weight, and then compression molded at 51 MPa (3.7 tons/in(2)) and 174 degrees C (345 degrees F). Molded specimens were then tested for tensile strength. Tensile yield strengths ranged from 32 MPa (4,700 psi) to 7.6 MPa (1,100 psi), while the engineering strain ranged from 0.6% to 1.25%. Results indicate that DDGS concentrations between 25% and 50% retained sufficient mechanical strength and thus represent reasonable inclusion values. Additionally, data were similar to those from other studies that have investigated biofillers. Follow-up studies should quantify the effects of altering molding parameters, including molding pressure, temperature, and time, as well as pretreatment of the DDGS. Additionally, strength of the DDGS composites should be optimized through the use of coupling agents or other additives. C1 No Illinois Univ, Dept Technol, De Kalb, IL 60115 USA.

Fat content of the dry flours influenced rheological changes, as dispersions of higher-fat flours were less viscous than lower-fat flours on an equal weight basis. A roast effect was also apparent, especially for dispersions of the higher-fat flours in which light roast flours were more viscous than dark roast flours. Dispersions of toasted soy flour were more viscous at lower temperatures (< 75C), but at higher temperatures, low-fat peanut flour dispersions were more viscous than soy. Centrifugal separation revealed that the insoluble material of all dispersions primarily contributed to the observed rheological responses. Sodium dodecyl sulfate-polyacrylamide gel electrophoresis was used to characterize the soluble and insoluble proteins making up the various dispersions, and these results are discussed in terms of observed rheological phenomena.

Design: The length of the experiment was 136 days. Subjects were fed a basal Western-type diet that provided 4.16 mmol (101 mg) magnesium per 8.4 MJ (2000 kcal) for 78 days then replenished with magnesium by supplementing the diet with 200 mg magnesium as the gluconate per day for 58 days. If a subject exhibited adverse heart rhythm changes before 78 days of depletion were completed, she entered the repletion period early. Setting: The metabolic research unit of the Grand Forks Human Nutrition Research Center. Subjects: A total of 14 post menopausal women were recruited by advertisement throughout the United States. Thirteen women (ages 47 to 75 years) completed the study. Results: During magnesium depletion, heart rhythm changes appeared in 5 women and resulted in 4 prematurely entering the magnesium repletion period (42 to 64 days of depletion instead of 78). Three women exhibited atrial fibrillation and flutter that responded quickly to magnesium supplementation. Magnesium deprivation resulted in a non-positive magnesium balance that became highly positive with magnesium repletion. Magnesium deprivation decreased red blood cell membrane magnesium, serum total cholesterol and erythrocyte superoxide dismutase concentrations, increased the urinary excretion of sodium and potassium, and increased serum glucose concentration. Conclusions: Magnesium balance may be a suitable indicator of magnesium depletion under experimental conditions. Magnesium deficiency resulting from feeding a diet that would not be considered having an atypical menu induces heart arrhythmias, impairs glucose homeostasis, and alters cholesterol and oxidative metabolism in post menopausal women. A dietary intake of about 4.12 mmol (100 mg) Mg/8.4 MJ is inadequate for healthy adults and may result in compromised cardiovascular health and glycemic control in post menopausal women.

TI Dietary linolenic acid intake is positively associated with five-year change in eye lens nuclear density SO JOURNAL OF THE AMERICAN COLLEGE OF NUTRITION LA English DT Article DE lens opacities; cataract; diet; fatty acids; women; linolenic acid ID FOOD FREQUENCY QUESTIONNAIRE; CATARACTOUS HUMAN LENSES; UNITED-STATES; NUTRIENT INTAKE; FAT; OPACITIES; PLASMA; WOMEN; RISK; REPRODUCIBILITY AB Objective: Dietary fat may affect lens cell membrane composition and function, which are related to age-related cataract. The present study was designed to examine the associations between dietary fat and the change in nuclear lens opacification over five years. Methods: Women aged 52 to 73 years without previously diagnosed cancer, diabetes and cataracts from the Boston, Massachusetts area were selected from the Nurses' Health Study cohort. Four hundred forty women participated in a baseline (1993-95) and a follow-up (1998-2000) eye examination. Intakes of total fat and selected fatty acids were calculated as the average intake from five food frequency questionnaires that were collected between 1980 and baseline. Change in the degree of nuclear density (opacification) was characterized by the difference between baseline and follow-up in pixel density at the central clear zone in the Scheimpflug slit image of the lens. Results: Intake of alpha-linolenic acid (ALA) was positively associated with change in nuclear density. The geometric mean nuclear density change was 16% greater in the highest quartile category of ALA intake than in the lowest quartile category (P for trend = 0.05). For women in the high tertile category of baseline nuclear lens opacification, the geometric mean change in the highest quartile category of ALA acid intake was 70% higher than the change in the lowest quartile category (P for trend = 0.01). There were no significant associations between other dietary fats and change in nuclear density. Conclusion: Higher ALA intake was associated with a greater age-related change in lens nuclear density. C1 Tufts Univ, USDA, Human Nutr Res Ctr Aging, Nutr Epidemiol Program, Boston, MA 02111 USA.

TI Plasma antioxidant capacity changes following a meal as a measure of the ability of a food to alter in vivo antioxidant status SO JOURNAL OF THE AMERICAN COLLEGE OF NUTRITION LA English DT Article DE oxygen radical absorbance capacity (ORAC(FL)); blueberries; grapes; kiwifruit; strawberry; cherry; dried plums; antioxidant capacity ID FRUCTOSE-INDUCED HYPERURICAEMIA; CORONARY HEART-DISEASE; COMMON FOODS; CHLOROGENIC ACID; UNITED-STATES; NORMAL CONSUMPTION; VEGETABLE INTAKE; ELDERLY-WOMEN; RISK; ANTHOCYANINS AB Objective: Determine 1) if consumption of a meal of different fruits or berries increases plasma hydrophilic (H-) or lipophilic (L-) antioxidant capacity (AOC) measured as Oxygen Radical Absorbance Capacity (ORAC(FL)); 2) if including macronutrients in the meal alters postprandial changes in AOC; and 3) if preliminary recommendations can be developed for antioxidant intake. Methods: Changes in plasma AOC following consumption of a single meal of berries/fruits (blueberry, dried plum, dried plum juice, grape, cherry, kiwifruit and strawberry) were studied in 5 clinical trials with 6-10 subjects per experiment. In two studies with blueberry or grape, additional macronutrients (carbohydrate, fat, protein) were included in the control and treatment meals. Blood samples collected before and after the meal were analyzed for AOC. Results: Consumption of dried plums or dried plum juice did not alter either the H- or L-AOC area under the curve (AUC). Consumption of blueberry in 2 studies and of mixed grape powder [12.5 (Study #1), 39.9 (Study #4) and 8.6 (Study #5) mmole Trolox Equivalents (TE) AOC, respectively] increased hydrophilic AOC AUC. L-AOC increased following a meal of blueberry containing 12.5 mmole TE AOC (Study #1). Consumption of 280 g of cherries (4.5 mmol TE AOC) increased plasma L-AOC but not H-AOC. The AOC in the control groups in which additional macronutrients (Studies #4 and #5) were added decreased from the postprandial baseline AOC measurement. Conclusion: We have demonstrated that consumption of certain berries and fruits such as blueberries, mixed grape and kiwifruit, was associated with increased plasma AOC in the postprandial state and consumption of an energy source of macronutrients containing no antioxidants was associated with a decline in plasma AOC. However, without further long term clinical studies, one cannot necessarily translate increased plasma AOC into a potential decreased risk of chronic degenerative disease. Preliminary estimates of antioxidant needs based upon energy intake were developed. high antioxidant foods with each meal is recommended in order to prevent periods of postprandial oxidative stress. Consumption of high antioxidant foods with each meal is recommended in order to prevent periods of postprandial oxidative stress. C1 Arkansas Childrens Nutr Ctr, USDA, Little Rock, AR 72202 USA.

To monitor these reactions, we had added fluorescently labeled proteins to stock solutions and examined the resultant filled leather using a microscope equipped with an epi-fluorescent attachment. In this present study, based on our understanding of the effect that enzyme modification will have on physical properties of crosslinked proteins, we polymerized potential filler products prior to their addition to the wet blue. We characterized the products with respect to their physical properties and molecular weight distribution (degree of polymerization). These products were applied to wet blue and evaluated, again using fluorescent labels to monitor their filling capability. It was shown that the proteins were evenly distributed throughout the hide and, more importantly, were not removed during the washing steps. Micrographs showing the location of fillers using fluorescent labels are presented. C1 USDA ARS, Eastern Reg Res Ctr, Wyndmoor, PA 19038 USA.

TI Acyl migration kinetics of 2-monoacylglycerols from soybean oil via H-1 NMR SO JOURNAL OF THE AMERICAN OIL CHEMISTS SOCIETY LA English DT Article DE acyl migration; ethanolysis; kinetics; 2-monoacylglycerol; H-1 NMR ID MONOGLYCERIDES AB The acyl migration kinetics of neat 2-monoacylglycerol (2-MAG) to form 1-MAG was determined using H-1 NMR spectroscopy to monitor the beta-proton integration ratios of the two species over time. 2-MAG was synthesized by the Novozym 435-catalyzed alcoholysis of soybean oil and isolated by solvent extraction or molecular distillation at a mole fraction (X (2-MAG)) of 0.94 relative to total MAG. The kinetics parameters of the neat 2-MAG acyl migration were investigated over the temperature range of 23-80 degrees C. The 2-MAG mol fraction remained unchanged at 23 degrees C over the course of 168 h and reached an equilibrium of X (2-MAG) = 0.09 at only 80 degrees C. Modeling of the kinetics data revealed a 2-MAG half life (t (1/2)) of 3,500 and 22.8 h at 23 and 80 degrees C, respectively, with an activation energy of 79.0 +/- 6.5 kJ mol(-1). The use of H-1 NMR spectroscopy proved an expedient method for monitoring the acyl migration in 2-MAG compared to other reported methods (e.g. GC, HPLC, and C-13-NMR spectroscopy), requiring no sample manipulation and minimizing the deleterious effects of high temperatures and solvent exposure.

TI Fatty acids in vernonia produced in the mid-atlantic region of the united states SO JOURNAL OF THE AMERICAN OIL CHEMISTS SOCIETY LA English DT Article DE Vernonia galamensis; vernolic acid; oil content; fatty acids; epoxy acids ID ERUCIC-ACID; OIL; GLUCOSINOLATE; GALAMENSIS; SEEDS AB Vernonia galamensis [(Cass.) Less.] is a native of Ethiopia and Eritrea. Seed of vernonia contain substantial quantities of naturally epoxidized oil, which is used in the paint industry to reduce emissions of volatile organic compounds that produce smog resulting from the use of petroleum-based (alkyd-resin) paint. Epoxidized oil is also used in the manufacture of plasticizers, additives to polyvinyl chloride, polymer blends and coatings, and cosmetic and pharmaceutical applications. Previous research has indicated that vernonia has potential for commercialization in the mid-Atlantic region of the United States. This study characterized fatty acids in oil from vernonia grown in this latter region. Vernonia oil, from 14 vernonia lines grown during 1995 and 1996 under field conditions in Virginia, contained 3.3, 3.0, 5.0, 15.0, 0.2, 0.5, 0.4, and 72.7%, respectively, of C16:0, C18:0, C18:1, C18:2, C18:3, C20:0, C20:1, and vernolic (C18:1 epoxy) fatty acids. Effects of genotypes on vernonia oil quality were generally not significant whereas the effects of years were significant. The concentration of vernolic acid was positively correlated with oil concentration but negatively correlated with concentrations of all individual fatty acids, except for C18:3.

TI Sound survey designs can facilitate integrating stream monitoring data across multiple programs SO JOURNAL OF THE AMERICAN WATER RESOURCES ASSOCIATION LA English DT Article DE monitoring; rivers/streams; statistics; stream surveys; stream condition; watershed condition ID ECOSYSTEM MANAGEMENT; NATURAL-RESOURCES AB Multiple agencies in the Pacific Northwest monitor the condition of stream networks or their watersheds. Some agencies use a stream "network" perspective to report on the fraction or length of the network that either meets or violates particular criteria. Other agencies use a "watershed" perspective to report on the health or condition of watersheds. The agencies often use the same indicators and measurement protocols for data collection and often conduct monitoring in overlapping geographic regions. In these situations, agencies would like to combine data across different monitoring studies in a statistically sound manner to make regional estimates of condition. Three statistical survey design principles will facilitate combining such studies: (1) a clearly specified statistical target population of interest, including elements that comprise the population, (2) a consistent representation of that target population (such as a digital map of the stream network and watersheds), and (3) rules that incorporate randomization to guide the selection of the sample of sites on which measurements will be made. A case study illustrates the application of these design principles using two agency monitoring programs interested in combining stream channel data for different purposes: one for making network summaries and the other for evaluating watershed condition.

By manipulating the surface of the nesting site, we compared 3-dimensional configurations of three different depths (1 cm, 2 cm, and 6 cm) and three different color contrasts (black-black, black-gray, and black-blue). We also tested the relative importance of third dimension and color contrast by manipulating both variables. Both species respond to changes in depth as well as in color contrast by increasing searching time and by displaying behaviors consistent with disorientation. Increasing the depth of the 3-dimensional configuration as well as the amount of color contrast led to an increase in the level of confusion. C1 Utah State Univ, Dept Biol, Logan, UT 84322 USA.

The RT-PCR equivalent sensitivities observed within seeded oysters as compared to virus stocks were 0.68, 6.8, 26, 5.6, and 14.5 RT-PCR50 units when assaying 10% of total RNA extracted from seeded oyster extracts for CAV9, CBV5, AiV, FCV, and MNV-1, respectively. For oysters exposed to virus-contaminated seawater, the detection equivalent sensitivities observed were 680, 68, 2600, 560, and 14.5 RT-PCR50 for CAV9, CBV5, AiV and FCV, and MNV-1, respectively. These results indicate that the GPTT method can be used as a general viral RNA extraction method for multiple picornaviruses and caliciviruses that could potentially contaminate shellfish.

Histological lesions in the brain and distribution of P. odocoilei in the muscles of experimentally and naturally infected sheep were consistent with a previously hypothesized "central nervous system to muscle" pattern of migration for P. odocoilei. Dimensions of granulomas associated with eggs of P. odocoilei and density of protostrongylid eggs and larvae in the cranial lung correlated with intensity of larvae in feces, and all varied with season of collection. Prevalence of P. stilesi based on the presence of larvae in feces underestimated true prevalence (based on examination of lungs) in wild Dall's sheep collected in summer and fall. Similarly, counts of both types of protostrongylid larvae in feces were unreliable indicators of parasitic infection in wild Dall's sheep with concomitant bacterial pneumonia associated with Arcanobacterium pyogenes, Pasteurella sp., and Mannheimia sp. Diffuse, interstitial pneumonia due to P. odocoilei led to fatal pulmonary hemorrhage and edema after exertion in one experimentally infected Stone's sheep and one naturally infected Dall's sheep. Bacterial and verminous pneumonia associated with pathogens endemic in wild Dall's sheep in the Mackenzie Mountains caused sporadic mortalities. There was no evidence of respiratory viruses or bacterial strains associated with domestic ruminants, from which this population of wild sheep has been historically isolated.

TI Raptor mortality due to West Nile virus in the United States, 2002 SO JOURNAL OF WILDLIFE DISEASES LA English DT Article DE avian disease; avian viral infection; histopathology; raptor mortality; West Nile virus ID EXPERIMENTAL-INFECTION; ENCEPHALITIS; FLAVIVIRUS; FIXATION; BIRDS AB West Nile virus (WNV) has affected many thousands of birds since it was first detected in North America in 1999, but the overall impact on wild bird populations is unknown. In mid-August 2002, wildlife rehabilitators and local wildlife officials from multiple states began reporting increasing numbers of sick and dying raptors, mostly red-tailed hawks (Buteo jamaicensis) and great horned owls (Bubo virginianus). Commonly reported clinical signs were nonspecific and included emaciation, lethargy, weakness, inability to perch, fly or stand, and nonresponse to danger. Raptor carcasses from 12 states were received, and diagnostic evaluation of 56 raptors implicated WNV infection in 40 (71%) of these cases. Histologically, nonsuppurative encephalitis and myocarditis were the salient lesions (79% and 61%, respectively). Other causes of death included lead poisoning, trauma, aspergillosis, and Salmonella spp. and Clostridium spp. infections. The reason(s) for tbe reported increase in raptor mortality due to WNV in 2002 compared with the previous WNV seasons is unclear, and a better understanding of the epizootiology and pathogenesis of the virus in raptor populations is needed.

Serum samples were tested for antibodies to viruses, bacteria, and parasites known to cause morbidity and mortality in other marine mammal species. Antibodies were found to phocine herpesvirus-1 by using an enzyme-linked immunosorbent assay, but seropositive results were not confirmed by virus neutralization test. Antibodies to Leptospira bratislava, L. hardjo, L. icterohaemorrhagiae, and L. pomona were detected in seals from several sites with the microagglutination test. Antibodies to Brucella spp. were detected using 10 conventional serologic tests, but because of inconsistencies in test results and laboratories used, and the lack of validation by culture, the Brucella serology should be interpreted with caution. Antibodies to B. canis were not detected by card test. Chlamydophila abortus antibodies were detected by complement fixation (CF) test, and prevalence increased significantly as a function of age; the low sensitivity and specificity associated with the CF make interpretation of results difficult. Antibodies to Toxoplasma gondii and Dirofilaria immitis were rarely found. There was no serologic evidence of exposure to four morbilliviruses, influenza A virus, canine adenovirus, caliciviruses, or other selected viruses. Continuous surveillance provides a means to detect the introduction or emergence of these or other infectious diseases, but it is dependent on the development or improvement of diagnostic tools. Continued and improved surveillance are both needed as part of future conservation efforts of Hawaiian monk seals. C1 Wildlife Trust, New York, NY 10001 USA.

Clinic, hospital, and county public health records (1998-2002) were examined to determine direct costs for postexposure prophylaxis (PEP), and 55 (41%) former patients were contacted to voluntarily provide estimates of their indirect costs associated with receiving PEP. Additional costs due to public health and animal control personnel responses to rabid animals were collected, including diagnostic testing and wages. The mean total cost of a suspected human rabies exposure was $3,688, the direct costs per case were $2,564, and the indirect costs were $1,124 of that total. About one third of the total cost for suspected human rabies exposure was attributed to indirect costs (e.g., lost wages, transportation, and day-care fees), most of which were not reimbursable to the patient.

From 1998-2002, we back-tracked radiocollared lynx (6 F, 9 M) for a distance of 582 km and we located 86 kills in northwestern Montana, USA. Lynx preyed on 7 species that included blue grouse (Dendragapus obscurus), spruce grouse (Canachites canadensis), northern flying squirrel (Glaucomys sabrinus), red squirrel (Tamiasciurus hudsonicus), snowshoe hare (Lepus americanus), least weasel (Mustela nivalis), and white-tailed deer (Odocoileus virginianus). Snowshoe hares (69 kills) accounted for 96% (4-yr average, range = 94-99%) of prey biomass during the sample period. Red squirrels were the second-most-common prey (11 kills), but they only provided 2% biomass of the winter diet. Red squirrels contributed little to the lynx diet despite low hare densities. A logistic regression model of snowshoe hare, red squirrel, and grouse abundance, as indexed by the number of track crossings of use and available lynx back-tracks, was a significant (Wald statistic = 19.03, df = 3, P < 0.001) predictor of habitat use. As we expected, lynx (P < 0.001) selected use-areas with higher snowshoe hare abundance compared to random expectation. However, the red squirrel index had a weak (P = 0.087) negative relationship to lynx use, and grouse was nonsignificant (P = 0.432). Our results indicate that lynx in western Montana prey almost exclusively on snowshoe hares during the winter with little use of alternative prey. Thus, reductions in horizontal cover for hares would degrade lynx habitat. C1 US Forest Serv, Rocky Mt Res Stn, Forestry Sci Lab, Missoula, MT 59807 USA.

Land managers need to know how land uses affect the quantities and species of fruit produced in different forest types and how fruit production varies seasonally and as young stands mature. During June 1999-April 2004, we quantified fleshy fruit abundance monthly in 31 0.1-ha plots in 2 silvicultural treatments: 1) young 2-age stands with low basal area retention, created by shelterwood-with-reserves regeneration cuts (R; harvested 1998-1999); and 2) uncut mature closed-canopy stands (M) in 2 common southern Appalachian, USA, forest types (upland hardwood and cove hardwood [CH] forests). Over the 5-year study period, total dry pulp biomass production was low and relatively constant in both M forest types (x = 0.5-2.0 kg/ha). In contrast, fruit production increased each year in R, and it was 5.0 to 19.6 times greater in R than in M stands beginning 3-5 years postharvest. Two disturbance-associated species, pokeweed (Phytolacca americana) and blackberry (Rubus allegheniensis), produced a large proportion of fruit in R but showed different patterns of establishment and decline. Huckleberry (Gaylussacia ursina) recovered rapidly after harvest and was a major producer in both silvicultural treatments and forest types each year. Several herbaceous species that are not associated with disturbance produced more fruit in CHR. Few species produced more fruit in M than in R. Fruit production by most tree species was similar between R and M, due to fruiting by stump sprouts in R within 1-3 years postharvest. Fruit availability was highest during summer and early fall. American holly (Ilex opaca), sumac (Rhus spp.), and greenbriar (Smilax spp.) retained fruit during winter months but were patchy in distribution. In the southern Appalachians, young recently regenerated stands provide abundant fruit compared to mature forest stands and represent an important source of food for wildlife for several years after harvest. Fruit availability differs temporally and spatially because of differences in species composition, fruiting phenology, and the dynamic process of colonization and recovery in recently harvested stands. Land managers could enhance fruit availability for many game and nongame species by creating or maintaining young stands within forests.

TI Avian nest box selection and nest success in burned and unburned southwestern riparian forest SO JOURNAL OF WILDLIFE MANAGEMENT LA English DT Article DE ash-throated flycatcher; Bewick's wren; Middle Rio Grande; riparian vegetation; secondary cavity-nesting; vegetation structure; wildfire ID CENTRAL NEW-MEXICO; RIO-GRANDE; REPRODUCTIVE SUCCESS; BIRDS; ECOSYSTEMS; PREDATION; HABITAT; FIRE; FRAGMENTATION; CONSERVATION AB Riparian forest communities in the southwestern United States were historically structured by a disturbance regime of annual flooding. In recent decades, however, frequency of flooding has decreased and frequency of wildfires has increased. Riparian forests provide important breeding habitat for a large variety of bird species, and the effects of this altered disturbance regime on birds and their breeding habitat is largely unknown. To evaluate effects of high-intensity spring and summer wildfire on the quality of breeding bird habitat in the Middle Rio Grande valley, we measured vegetation structure and composition, avian nest use, and nest success at 4 unburned plots and 4 wildfire plots over a 3-year period. We measured avian nest use and success at nest boxes located in unburned riparian forest plots and plots recently burned by wildfire. Recent wildfire plots (< 7 yr after fire) had a much different vegetation structure than unburned plots; an older (> 7 yr after fire) wildfire plot more closely resembled its paired unburned plot than did recently burned plots. Ash-throated flycatchers (Myiarchus cinerascens) and Bewick's wrens (Thryomanes bewickii; hereafter, flycatchers and wrens, respectively) used nest boxes in most of the plots. A model selection procedure applied to logistic regressions showed that frequency of nest box use by flycatchers was positively associated with wildfire, although flycatchers used boxes in unburned plots as well. Wrens showed a preferential use of nest boxes that were in unburned sites and in close proximity to vegetative cover. Growth rates, feeding rates, and fledging mass of flycatchers were similar in wildfire and unburned plots. Growth rates for wrens were slower in wildfire plots, while feeding rates and fledging mass were similar. Nest predation varied between years, was higher for flycatchers than for wrens, and was not directly influenced by wildfire. Model selection showed that predation increased with grass cover, an indicator of forest openness, and decreased with distance to habitat edge. Recovery of dense vegetation appears important in maintaining populations of Bewick's wrens, whereas ash-throated flycatchers were less sensitive to vegetative structure and composition of postfire succession. Postfire management that maintains nest sites in large forest strips would enhance nesting density and success of these cavity-nesting birds in riparian zones.

TI Habitat selection by American martens in coastal California SO JOURNAL OF WILDLIFE MANAGEMENT LA English DT Article DE California; coastal forest; habitat selection; marten; Martes americana; shrub cover ID FORESTS; OREGON; SITES AB We investigated habitat selection using single- and mixed-scale modeling at 2 spatial scales, stand and home range, by the only known population of American martens (Martes americana) remaining in the historical range of the Humboldt subspecies (M a. humboldiensis) in California, USA. During 2000 and 2001, we sampled a 12 X 14 grid with 2-km spacing, using 2 sooted track plates at each grid point. We detected martens at 26 of the 159 grid points. We used resource selection probability functions and an information-theoretic method to model habitat at detection locations. At the stand scale, martens selected conifer-dominated stands with dense, spatially extensive shrub cover (x = 74% cover, SE = 4) in the oldest developmental stage. At the home-range scale, martens selected the largest available patches (k = 181 ha, SE = 14) of old-growth, old-growth and late-mature, or serpentine habitat. Mixed-scale models revealed that habitat characteristics from both scales best explained marten occurrence compared to one scale alone. Dense, spatially extensive shrub cover is a key habitat element for martens in coastal forests. Dense shrubs provide refuge from predators, cover for prey, and may also deter larger-bodied competitors. Managers can increase the likelihood of marten population persistence and encourage expansion in coastal forests by maintaining and restoring late-mature and old-growth, conifer-dominated forests with dense shrub cover in large, contiguous patches.

TI Coyote investigative behavior following removal of novel stimuli SO JOURNAL OF WILDLIFE MANAGEMENT LA English DT Article DE attractant; behavior; Canis latrans; coyote; novel stimuli; scent-station; vision ID PREDATORY BEHAVIOR; RESPONSES; SENSES; DEER AB Because coyotes (Canis latrans) show an aversion to novel objects, we examined the effects of the presence and removal of repellent and attractive stimuli on coyote behavior. We found a greater proportion of captive coyotes investigated 10-cm-tall cones (0.95) compared to 90-cm-tall cones (0.68) and control sites (0.81), and spent longer periods (P < 0.001 in all instances) investigating small cones (<(x)over bar> = 465 see), compared to large cones ((x) over bar = 212 sec) and control sites ((x) over bar = 45 sec). However, investigation times at sites following removal of large cones were 1.6 and 2.3 times greater than investigation times at sites following removal of;mall cones and the control, respectively. Results from pen studies were supported by a field study. Wild coyotes in south Texas visited 43% of small cones but did not visit large cones. Following removal of cones, visits to small cone stations decreased to 29%, whereas coyotes visited 43% of large cone stations. Thus, we observed a direct relationship between aversion toward large novel objects and subsequent attraction to sites following their removal among both captive and wild coyotes. Based upon our results, we suggest that placing large novel objects over traps that are set and removing such objects after a few days, with the subsequent addition of an olfactory attractant, may increase exploratory behavior and capture of coyotes.

We studied the presence and significance of WNV titers in free-roaming black bears (Ursus americanus) in northeastern Wisconsin between February 2003 and March 2005. Serum neutralizing antibodies to WNV, with confirmation by plaque-reduction neutralization test to both WNV and Saint Louis encephalitis, identified exposure in 13 of 74 (17.6%) bears. This compares with a 6% infection rate in black bears in Virginia and 22% in European brown bears (Ursus arctos). Pathologic effects from exposure to WNV were not seen in any of the black bears studied. C1 Univ Wisconsin, Cofrin Ctr Biodivers, Green Bay, WI 54311 USA. US Forest Serv, Laona, WI 54541 USA.

The total phenol content (TPC) of the extracts was determined by the Folin-Ciocalteu method and expressed as gallic acid equivalent (GAE). Butylated hydroxytoluene was used as a positive control in the free-radical-scavenging activity tests and ethylenediaminetetraacetic acid dihydrate disodium salt served as a positive control in the metal-chelating activity assay. All wood extracts showed significant freeradical-scavenging activity. In the radical-scavenging assay of 2,2-azino-bis (3-ethylbenzothiazoline-6-sulfonic acid) diammonium salt (the ABTS assay), the inner bark extracts exhibited the strongest free-radical-scavenging activity. The 50% inhibitory concentrations (IC50) in the radical-scavenging assay against 1,1-diphenyl-2-picrylhydrazyl hydrate radical (DPPH) of the heartwood, sapwood, and inner and outer bark extracts were 64.77, 29.03, 10.31, 19.87 mu g.ml(-1), respectively. In the metal-chelating activity system, the sapwood extract demonstrated significant activity. The greatest TPC, 537.5 mg GAE/g dry extract, was detected in the inner bark. The lowest TPC of 136.9 mg GAE/g dry extract was observed in the heartwood dry extract. The results indicate that the antioxidant activities of the extracts are in accordance with the amounts of phenolics present; the inner and outer barks of Port Orford cedar are rich in phenolics and may provide good sources of antioxidants.

We used temporal land-cover data for the Chesapeake Bay region and the state of New Jersey to compare patch-based and area-density scaling measures of fragmentation for detecting changes in the spatial scale of forest that may result from forest loss. For the patch-based analysis, we examined changes in the cumulative distribution of patch sizes. For area-density scaling, we used moving windows to examine changes in dominant forest. We defined dominant forest as a forest parcel (pixel) surrounded by a neighborhood in which forest occupied the majority of pixels. We used > 50% and >= 60% as thresholds to define majority. Moving window sizes ranged from 2.25 to 5,314.41 hectares (ha). Patch size cumulative distributions changed very little over time, providing no indication that forest loss was changing the spatial scale of forest. Area-density scaling showed that dominant forest was sensitive to forest loss, and the sensitivity increased nonlinearly as the spatial scale increased. The ratio of dominant forest loss to forest loss increased nonlinearly from 1.4 to 1.8 at the smallest spatial scale to 8.3 to 11.5 at the largest spatial scale. The nonlinear relationship between dominant forest loss and forest loss in these regions suggests that continued forest loss will cause abrupt transitions in the scale at which forest dominates the landscape. In comparison to the Chesapeake Bay region, dominant forest loss in New Jersey was less sensitive to forest loss, which may be attributable the protected status of the New Jersey Pine Barrens.

Due to the presence of the toxin ricin and potent allergenic 2S albumins in the seed, it is desirable to produce ricinoleate from temperate oilseeds. To identify regulatory genes or genes for enzymes that may up-regulate multiple activities or entire pathways leading to the ricinoleate and TAG synthesis, we have analyzed expression profiles of 12 castor genes involved in fatty acid and TAG synthesis using quantitative reverse transcription-polymerase chain reaction technology. A collection of castor seeds with well-defined developmental stages and morphologies was used to determine the levels of mRNA, ricinoleate and TAG. The synthesis of ricinoleate and TAG occurred when seeds progressed to stages of cellular endosperm development. Concomitantly, most of the genes increased their expression levels, but showed various temporal expression patterns and different maximum inductions ranging from 4- to 43,000-fold. Clustering analysis of the expression data indicated five gene groups with distinct temporal patterns. We identified genes involved in fatty acid biosynthesis and transport that fell into two related clusters with moderate flat-rise or concave-rise patterns, and others that were highly expressed during seed development that displayed either linear-rise or bell-shaped patterns. Castor diacylglycerol acyltransferase I was the only gene having a higher expression level in leaf and a declining pattern during cellular endosperm development. The relationships among gene expression, cellular endosperm development and ricinoleate/TAG accumulation are discussed. C1 USDA ARS, Western Reg Res Ctr, Albany, CA 94710 USA.

In this method, capacitance (C), phase angle (theta) and dissipation factor (D) were measured with an impedance analyser at 1 and 5 MHz on a parallel-plate capacitor holding a few kernels of a particular commodity between the plates. These values were then used in an empirical equation based on the parameters C, theta and D, and the moisture content was calculated. The calculated mc values were within 1% of the air-oven values for about 85% of the kernel samples tested in the moisture range from 6% to 20% for wheat, corn and peanuts. However, it would be useful during drying and processing of peanuts, if the mc could be determined without shelling them. In this work, the feasibility of determining the moisture content of in-shell peanuts (pods) by similar impedance measurements was investigated. Values of capacitance, phase angle and dissipation factor measured at 24 degrees C and at three frequencies were used in a modified prediction equation and the moisture content was estimated within 1% of the air-oven values for over 90% of the pod samples tested in the moisture range from 6% to 25%. The method is rapid and nondestructive and may be used in the development of a commercial instrument. C1 USDA ARS, Dawson, GA USA. USDA ARS, Athens, GA 30613 USA.

The main goal of the method was to enable different moisture meter models to provide equivalent moisture predictions without calibration development. The database that was used to create and test the method included 6189 grain samples representing 53 grain types of US grain that were collected over a period of 6 years. The overall standard deviation of differences with respect to the air-oven method was 0.34% moisture. Methods for transferring grain moisture calibrations from the original 'Master' test cell to a smaller test cell were developed and tested. Three temperature correction functions with differing levels of complexity were evaluated. The algorithm is available as a public algorithm for commercialization by multiple manufacturers.

As a prerequisite to marker assisted breeding, genetic linkage maps are currently being developed for many species. For many purposes gene-based markers are the marker type of choice. The biggest problem in genetic linkage mapping using gene-based markers is the identification of polymorphisms between the parents of the population. To improve the efficiency of marker generation, we have developed a simple, and reasonable-cost method of polymorphism detection termed dideoxy polymorphism scanning. Since most of the time required to develop a gene-based linkage map is spent in identification of useful polymorphisms, this method will significantly shorten the time required for map generation and therefore reduce the overall cost.

Seven genes identified by suppression subtractive hybridization as up-regulated in the mesenteric lymph nodes at 24 h (h) post-inoculation (p.i.) in serovar Choleraesuis-infected pigs (ARPC2, CCT7, HSPH1, LCP1, PTMA, SDCBP, VCP) and three genes in serovar Typhimurium-infected pigs (CD47/IAP, CXCL 10, SCARB2) were analyzed by real-time PCR at 8 h, 24 h, 48 h, 7 days (d) and 21 d p.i. A comparison between the two Salmonella infections revealed significant differences in transcriptional induction early in the infection (8-24 h) for the serovar Typhimurium-infected pigs, whereas the serovar Choleraesuis-infected pigs exhibited significantly higher levels of gene expression at the later time points (48 h-21 d), except for HSPH1. A similar gene expression trend was observed for immune-related genes involved in innate immunity and the inflammatory T helper 1 (Th1) response. Initial repression of gene expression in the serovar Choleraesuis-infected pigs from 8 to 48 h p.i. (IFNG, IL12A, IL4, IL8, CSF2) coincided with extended transcriptional activation throughout the 21 d infection (IFNG, INDO, SOCS1, STAT1, IL1B, IL6, IL8, SLC1 1A1). The serovar Typhimurium-infected swine presented a more transient induction of immune-related genes (IFNG, INDO, IRF1, SOCS1, STAT1, IL1B, IL8, SLC1 1A1) early in the infection (24-48 h) followed by a significant repression of IL12A, IL12B, IL4, IL8 and CSF2. Collectively, these data reveal specific porcine genes with differences in gene expression kinetics that may be responsible for the variation in disease progression observed in swine infected with Typhimurium compared to Choleraesuis.

The striking similarity between the floras of eastern Asia and those of eastern North America and the difference in chestnut blight resistance among species has been of interest to botanists for a century. To infer the biogeographical history of the genus, the phylogeny of Castanea was estimated using DNA sequence data from different regions of the chloroplast genome. Sequencing results support the genus Castanea as a monophyletic group with Castanea crenata as basal. The three Chinese species form a strongly supported sister clade to the North American and European clade. A unique westward expansion of extant Castanea species is hypothesized with Castanea originating in eastern Asia, an initial diversification within Asia during the Eocene followed by intercontinental dispersion and divergence between the Chinese and the European/North American species during the middle Eocene and a split between the European and the North American species ill the late Eocene. The differentiation within North America and China might have occurred in early or late Miocene. The North America species are supported as a clade with C pumila var. ozarkensis, the Ozark chinkapin, as the basal lineage, sister to the group comprising C pumila var. pumila, the Allegheny chinkapin, and Castanea dentata, the American chestnut. Morphological evolution of one nut per bur in the genus may have occurred independently on two continents. (c) 2006 Elsevier Inc. All rights reserved. C1 Auburn Univ, Dept Hort, Auburn, AL 36849 USA.

Analysis of the M. perniciosa draft genome led to the identification of three putative genes encoding necrosis and ethylene -inducing proteins (MpNEPs), which are apparently located on the same chromosome. MpNEP1 and 2 have highly similar sequences and are able to induce necrosis and ethylene emission in tobacco and cacao leaves. MpNEP1 is expressed in both biotrophic and saprotrophic mycelia, the protein behaves as an oligomer in solution and is very sensitive to temperature. MpNEP2 is expressed mainly in biotrophic mycelia, is present as a monomer in solution at low concentrations (<40 pm) and is able to recover necrosis activity after boiling. These differences indicate that similar NEPs can have distinct physical characteristics and suggest possible complementary roles during the disease development for both proteins. This is the first report of NEP1-like proteins in a basidiomycete. (C) 2007 The British Mycological Society. Published by Elsevier Ltd. All rights reserved.

Infected seeds and vegetative organs of infected host plants are the only known modes of propagation of the asexual endophytes. In the last decade certain Epichloe and Neotyphodium-infected grass species have been shown to have epiphyllous structures of the endophytes, hyphae, conidiophores, and conidia, growing on leaf blades. The production of epiphyllous conidia suggests the possibility that some of these endophytes may have the ability for plant-to-plant spread. The objective of this study was to determine the possible mechanisms involved in liberation and dispersal of asexual spores of Neotyphodium growing in vitro and epiphyllously on leaves of Poa ampla. Our results indicate that water dispersal is the most likely means of dissemination of conidia of the Neotyphodium sp. Wind generated by dry compressed air does not dislodge the conidia from slide cultures or from P. ampla leaves. (C) 2007 The British Mycological Society. Published by Elsevier Ltd.

Complex branching up to the sixth order was induced by compounds most soluble in 35 % methanol, whereas the formation of more lateral branches (second order) was stimulated by compounds most soluble in 70% methanol. This same 70 % alcohol soluble fraction also stimulated a completely different type of branching pattern in another fungus, Gigaspora gigantea. This pattern consisted of a very periodic distribution of dense clusters of hyphal branches that had a very high degree of complexity. In contrast to exudate components, separated cytosolic components of carrot roots did not stimulate any of the observed hyphal branching patterns. Alcohol-soluble fractions actually inhibited hyphal tip growth of G. gigantea and induced the formation of "recovery" branches that were identical to those induced by an inhibitor found in the exudate of Chard (Beta vulgaris ssp. cicla), a non-host plant.

A naturally occurring, nontoxigenic strain of A. flavus and a UV-induced mutant of A. parasiticus were applied to peanut soils during the middle of each of two growing seasons using a formulation of conidia-coated hulled barley. In addition to an untreated control, treatments included soil inoculated with nontoxigenic A. flavus only, soil inoculated with nontoxigenic A. parasiticus only, and soil inoculated with a mixture of the two nontoxigenic strains. Plants were exposed to late-season drought conditions that were optimal for aflatoxin contamination. Results from year one showed that significant displacement (70%) of toxigenic A. flavus occurred only in peanuts from plots treated with nontoxigenic A. flavus alone; however, displacement did not result in a statistically significant reduction in the mean aflatoxin concentration in peanuts. In year two, soils were re-inoculated as in year one and all treatments resulted in significant reductions in aflatoxin, averaging 91.6%. Regression analyses showed strong correlations between the presence of nontoxigenic strains in peanuts and aflatoxin reduction. It is concluded that treatment with the nontoxigenic A. flavus strain alone is more effective than the A. parasiticus strain alone and equally as effective as the mixture.

TI Two new species of Alternaria from pear fruit SO MYCOTAXON LA English DT Article DE Alternaria alternata ID THEMES AB Two new taxa in Alternaria are here described as A. calycipyricola from the calyces of fruits of Pyrus communis 'd'Anjou' grown in Washington State, and A. ventricosa from the stem of a fruit of Pyrus bretschneideri 'Ya Li' grown in Hebei, China. Conidia of both species are fundamentally erostrate but may produce elongate apical secondary conidiophores from which chain elongation and lateral branching occur late in the development of individual conidia. A. calycipyricola and A. ventricosa differ from each other in cultural characters, growth rate, and conidial morphology. Combined analyses of RAPD, RAMS and AFLP fingerprints support morphological evidence that A. calycipyricola and A. ventricosa are appropriately placed in the A. infectoria species-group sensu Simmons and are distinct from each other and the other species studied within the group.

The existence of the binomial Clonostachys rosea (Preuss) Mussat 1901 would render the more recently established C. rosea (Link: Fr.) Schroers et al. 1999 illegitimate. A textual analysis proves, however, that Mussat's combination Clonostachys rosea is invalid according to Article 34.1(a) and (c) of the international Code of Botanical Nomenclature. We know of no formally published instance where Preuss himself raised Clonostachys araucaria var. rosea Preuss to species level. Therefore, the name Clonostachys rosea Preuss, as it was listed by Mussat, cannot be regarded as valid either. Similarly, the binomials Alternaria citri (Penzig) Mussat, Alternaria macrospora (Sacc.)

However, the limited coverage of aspen in this area appears to carry a disproportionate biodiversity load: numerous species are dependent on the unique components of aspen forests for habitat. Land managers in the region believe the species is declining due to fire suppression policies of the past century. Recent research from other regions shows mixed results when assessing the extent of decline. This review focuses on the crossroads between human and natural history to describe a broader picture of aspen ecology in the Sierra Nevada. The method used here combines a review of the ecological literature with historical synthesis. A central conclusion is that the current "decline" in aspen must be placed in the context of an unusual regeneration pulse brought on by intensive Euro-American resource extraction activities of the late 19th century. We address unique features of the Sierra aspen population, the interface of climate change and human-caused disturbance, and conservation strategies for restoration of an aspen community more closely aligned with contemporary climate-disturbance cycles. Conservation recommendations include reintroduction of mixed-severity natural fires and complimentary wildlife, such as top predators, where practical, plus allowance for local flexibility where deviations are appropriate based on ecology and social concerns.

The recently released draft genomic sequence for the bee will accelerate honeybee behavioral genetics. Although we lack sufficient tools to manipulate this genome easily, quantitative trait loci (QTLs) that influence natural variation in behavior have been identified and tested for their effects on correlated behavioral traits. We review what is known about the genetics and physiology of two behavioral traits in honeybees, foraging specialization (pollen versus nectar), and defensive behavior, and present evidence that map-based cloning of genes is more feasible in the bee than in other metazoans. We also present bioinformatic analyses of candidate genes within,QTL confidence intervals (CIs). The high recombination rate of the bee made it possible to narrow the search to regions containing only 17-61 predicted peptides for each QTL, although CIs covered large genetic distances. Knowledge of correlated behavioral traits, comparative bioinformatics, and expression assays facilitated evaluation of candidate genes. An overrepresentation of genes involved in ovarian development and insulin-like signaling components within pollen foraging QTL regions suggests that an ancestral reproductive gene network was co-opted during the evolution of foraging specialization. The major QTL influencing defensive/aggressive behavior contains orthologs of genes involved in central nervous system activity and neurogenesis. Candidates at the other two defensive-behavior QTLs include modulators of sensory signaling (Am5HT(7) serotonin receptor, AmArr4 arrestin, and GABA-B-R1 receptor). These studies are the first step in linking natural variation in honeybee social behavior to the identification of underlying genes. C1 Purdue Univ, Dept Entomol, W Lafayette, IN 47907 USA.

Egg mass samples ranging in size from 15 to 46 g were placed on a screen platform above a magnetic stir bar in the respirometer; the degree of agitation was controlled with a magnetic stir plate. Dissolved oxygen (DO) concentration and temperature were measured with a luminescent DO sensor and meter. The respirometer was used to determine routine metabolic rate and limiting oxygen concentration (the presumed hypometabolic transition zone) on egg mass samples from 10 different spawns at 0 to 5 d postfertilization. Routine metabolic rate increased from 4.8 +/- 1.3 (0 d postfertilization) to 174.0 +/- 7.8 mg O-2 . kg(-1) h(-1) (5 d postfertilization). The limiting oxygen concentration increased similarly up to 87.0% +/- 2.7% (maximum individual value= 95.9%) air saturation by 5 d postfertilization. The respirometer described could not be used for sac fry, but it proved effective with clumped channel catfish eggs. Preliminary channel catfish hatchery management recommendations are to maintain DO concentrations in hatchery troughs at air saturation at least during the last day of egg development.

Showler, Allan TI Chemical cotton stalk destruction for maintenance of host-free periods for the control of overwintering boll weevil in tropical and subtropical climates SO PEST MANAGEMENT SCIENCE LA English DT Article DE boll weevil; herbicides; cotton regrowth; stalk destruction; stripper and picker harvest; 2,4-D AB In the Lower Rio Grande Valley (LRGV) of Texas, cotton regrows and produces fruit from undestroyed stalks throughout the winter, and in spring weevils from such locations become a serious threat. The success of the boll weevil eradication program, which was reintroduced in the LRGV in 2005, will be dependent on thorough stalk destruction following harvest. However, adverse weather conditions and conservation tillage often impede immediate and complete stalk destruction using typical tool implements, and alternative stalk control methods are needed. This study provides an examination of the efficacy for cotton stalk destruction of different herbicides (thifensulfuron-methyl + tribenuron-methyl, dicamba-diolamine, 2,4-D-dimethylammonium, flumioxazin, 2,4-DB-dimethylammonium and carfentrazone-ethyl) and their rates, spray volumes and application timings on shredded or standing cotton stalks after stripper or picker harvest. None of the tested herbicides, except 2,4-D-dimethylammonium, stopped post-harvest cotton regrowth and fruiting. 2,4-D-dimethylammonium sprayed once (0 or 7 days) after cotton was harvested at 1 lb AE acre(-1) (1.12 kg ha(-1)), in a spray volume of 10 gal water acre(-1) (93.5 L ha(-1)) with 5 mL L-1 surfactant, was highly effective in stalk destruction (72-90%). The best results were achieved when the herbicide was applied immediately after the cotton was shredded, followed by standing stripper-harvested and standing picker-harvested cotton. 2,4-D-dimethylammonium applied twice, 0 and 14 (or 21) days after cotton harvest, was 100% effective in killing stalks, regardless of whether they were shredded or standing, or whether harvest was by stripper or picker. These findings showed that 2,4-D-dimethylammonium cotton stalk destruction eliminated food and reproductive opportunities for managing overwintering boll weevils [Anthonomus grandis grandis Boheman (Coleoptera: Curculionidae)].

Merr.] has enabled highly effective and economical weed control. The concomitant increased application of glyphosate could lead to shifts in the soil microbial community. The objective of these experiments was to evaluate the effects of glyphosate on soil microbial community structure, function and activity. Field assessments on soil microbial communities were conducted on a silt loam soil near Stoneville, MS, USA. Surface soil was collected at time of planting, before initial glyphosate application and 14 days after two post-emergence glyphosate applications. Microbial community fatty acid methyl esters (FAMEs) were analyzed from these soil samples and soybean rhizospheres. Principal component analysis of the total FAME profile revealed no differentiation between field treatments, although the relative abundance of several individual fatty acids differed significantly. There was no significant herbicide effect in bulk soil or rhizosphere soils. Collectively, these findings indicate that glyphosate caused no meaningful whole microbial community shifts in this time period, even when applied at greater than label rates. Laboratory experiments, including up to threefold label rates of glyphosate, resulted in up to a 19% reduction in soil hydrolytic activity and small, brief (< 7 days) changes in the soil microbial community. After incubation for 42 days, 32-37% of the applied glyphosate was mineralized when applied at threefold field rates, with about 9% forming bound residues. These results indicate that glyphosate has only small and transient effects on the soil microbial community, even when applied at greater than field rates.

An examination of the transcript levels of arginine decarboxylase (ADC), ODC, S-adenosylmethionine decarboxylase (SAMDC) and spermidine synthase (SPDS), as well as their enzyme activities (except SPDS), showed that the expression of different members of the SAMDC and SPDS gene families was affected differently in response to alteration of the cellular Put content. It was further observed that there was a strong correlation between transcript levels and the activity of the respective enzyme in the cells. Moreover, there was no feedback inhibition of the expression of the native ODC or the ADC genes or their enzyme activities by increased Put in the cells.

Only one of two fumonisin B1 (FB1)-insensitive maize backcross lines was more resistant than the FB1-sensitive parent to seedling blight, indicating that the increase in FB1-insensitivity was not associated with an increase in resistance. FB1-producing and nonproducing isogenic fungal strains did not differ in ability to cause seedling blight, but the FB1-producing strain was more effective in systemic colonization of seedlings in reciprocal strain challenge tests. Together, these and previous results indicate that the role of fumonisins depends on complex environmental and genetic contexts in this host-pathogen interaction. Published by Elsevier Ltd.

Internode lengths and fresh weights of symptomatic plants were reduced, but not the sucrose concentrations. Starch and sucrose concentration in green leaf tops of mature (18 months old) was the highest in asymptomatic plants followed by symptomatic, and then by virus-free plants. Carbohydrates increased during daytime by 5-20%. The carbohydrate concentration in leaves of young, 6 months old plants was much lower than in mature plants and it increased to 500% during daytime. Asymptomatic leaves had a higher level of carbohydrates, especially starch, from late afternoon until the end of the night, suggesting a reduction of assimilate export. (c) 2007 Elsevier Ltd.

Two cDNAs exhibiting HMT activity were cloned from broccoli and functionally expressed in E. coli. One cDNA, that encodes an enzyme with high substrate specificity for homocysteine, was designated as BoHMT1. The other cDNA was the BoSMT gene that we previously characterized and encodes a selenocysteine methyltransferase (Lyi, S.M., Heller, L.I., Rutzke, M., Welch, R.M., Kochian, L.V., Li, L,, 2005. Molecular and biochemical characterization of the selenocysteine Se-methyltransferaSe gene and Se-methylselenocysteine synthesis in broccoli. Plant Physiol. 138, 409-420). Both exist as single gene sequences in the broccoli genome. While BoSMT expression was extremely low or undetectable in broccoli plants unless the plants were exposed to selenium, the BoHMT1 mRNA accumulated in most tissues of the plant except older leaves. In contrast to BoSMT whose expression was dramatically upregulated by treating plants with selenate, the transcript levels of BoHMT1 were not markedly affected in plants exposed to selenium. BoHMT1 expression responded significantly to changes in plant sulfur status. However, its expression was not dramatically affected in plants treated with methionine, SMM, homocysteine, or the heavy metal, cadmium. The differences in the substrate specificity and gene expression in response to changes in plant sulfur and selenium status between BoHMT1 and BoSMT suggest that the enzymes encoded by these two genes play distinct roles in sulfur and selenium metabolism in broccoli.

To gain insight into the mechanism by which T hamatum 382 induced resistance in tomato, high-density oligonucleotide microarrays were used to determine its effect on the expression pattern of 15,925 genes in leaves just before they were inoculated with the pathogen. T hamatum 382 consistently modulated the expression of genes in tomato leaves. We identified 45 genes to be differentially expressed across the replicated treatments, and 4 1 of these genes could be assigned to at least one of seven functional categories. T homatum 382-induced genes have functions associated with biotic or abiotic stress, as well as RNA, DNA, and protein metabolism. Four extensin and extensin-like proteins were induced. However, besides pathogenesis-related protein 5, the main markers of systemic acquired resistance were not significantly induced. This work showed that T hamatum 382 actively induces systemic changes in plant physiology and disease resistance through systemic modulation of the expression of stress and metabolism genes.

Regardless of plant source, seed meal amendment significantly improved apple growth in all orchard soils; however, relative differences in pathogen suppression were observed. All seed meals suppressed root infection by native Rhizoctonia spp. and an introduced isolate of Rhizoctonia solani AG-5, though B. juncea seed meal often generated a lower level of disease control relative to other seed meal types. When introduction of the pathogen was delayed until 4 to 8 weeks post seed meal amendment, disease suppression was associated with proliferation of resident Streptomyces spp. and not qualitative or quantitative attributes of seed meal glucosinolate content. Using the same experimental system, when soils were pasteurized prior to pathogen infestation, control of R. solani was eliminated regardless of seed meal type. In the case of B. juncea seed meal amendment, the mechanism of R. solani suppression varied in a temporal manner, which initially was associated with the generation of allylisothiocyanate and was not affected by soil pasteurization. Among those tested, only B. juncea seed meal did not stimulate orchard soil populations of Pythium spp. and infection of apple roots by these oomycetes. Although application of B. napus seed meal alone consistently induced an increase in Pythium spp. populations, no significant increase in Pythium spp. populations was observed in response to a composite B. juncea and B. napus seed meal amendment. Suppression of soil populations and root infestation by Pratylenchus spp. was dependent upon seed meal type, with only B. juncea providing sustained nematode control. Collectively, these studies suggest that use of a composite B. juncea and B. napus seed meal mixture can provide superior control of the pathogen complex inciting apple replant disease relative to either seed meal used alone.

Each population was defined as an interbreeding unit of conspecific individuals sharing a common recent ancestor and arising in a unique evolutionary event. The present study applies this standard to extend characterization of S. sclerotiorum populations to the Western United States. Isolates of S. sclerotiorum (N = 294) were determined to represent three genetically differentiated populations: California (CA, lettuce), Washington (WA, pea/lentil), and Ontario (ON, lettuce). CA was the most diverse population yet sampled in North America. Clonality was detected in ON and WA. No DNA fingerprints were common among the populations. The index of association (I-A), based on fingerprint, was closer to zero (0) for CA than it was for the other populations. High diversity and lack of association of markers in California are consistent either with genetic exchange and recombination, or with large population size and high standing genetic variation. Intra- and interlocus conflict among three DNA sequence loci was consistent with recombination. The coalescent IGS genealogy confirmed subdivision and showed CA to be older than WA or ON. The Nearest Neighbor statistic on combined data confirmed subdivision among all present and previously defined populations. All isolates had both MAT1-1 and MAT1-2, consistent with uniform homothallism. C1 Univ Toronto, Dept Ecol & Evolutionary Biol, Mississauga, ON L5L 1C6, Canada.

In this study, we used cultural characteristics, amplified fragment length polymorphism (AFLP), and DNA sequence analyses of the ribosomal internal transcribed spacer (ITS) region and mitochondrial cytochrome oxidase II (cox II) genes to characterize temperate and tropical isolates from a wide range of host species. All but one temperate isolate grew at 35 degrees C, while all tropical isolates did not, All but two tropical isolates formed chlamydospores, while temperate isolates did not. There was strong bootstrap support for separation of temperate and tropical isolates using AFLP analysis; however, the temperate isolates appeared as a subgroup within the observed variation of the tropical isolates. The majority of temperate isolates clustered within a single clade with low variation regardless of host or geographical origin, while the tropical isolates were more variable and grouped into three distinct clades. Two clades of tropical isolates grouped together and were affiliated closely with the temperate isolates, while the third tropical clade was more distantly related. Phylogenetic analysis of the ITS regions resulted in similar groupings and variation within and between the temperate and tropical isolates as with the AFLP results. Sequence divergence among isolates and clades was low, with more variation within the tropical isolates than within the temperate isolates. Analysis of other species revealed shorter branch lengths separating temperate and tropical isolates than were observed in comparisons among other phylogenetically closely related species in the genus. Analysis of Cox II sequence data was less clear. Although the temperate and tropical isolates grouped together apart from other species, there was no bootstrap support for separating these isolates. Restriction fragment length polymorphism (RFLP) analysis of the ITS regions separated the temperate and tropical isolates, as in the AFLP and ITS phylogenetic analyses. However, RFLP analysis of the cox I and II gene cluster did not distinguish between temperate and tropical isolates. The differences in grouping of isolates in these two RFLP studies should be helpful in identifying isolate subgroups. Our data do not fully clarify whether or not temperate and tropical isolates should be separated into different species. The available worldwide data are incomplete and the full range of variation in the species is not yet known. We suggest refraining from using the epithet P. tropicalis until more data are available.

To better understand the factors regulating the distribution of common/ representative species, endemic/rare species, and the threat of exotics in this important flora, we analyzed broad-scale community patterns and environmental conditions in a geographically stratified set of samples from across the state. We considered three major classes of environmental influences: climate ( especially precipitation), soils ( especially the Mg2+/ Ca2+ ratio), and the indirect influences of climate on soils. We used ordination to identify the major axes of variation in common species abundances, structural equation models to analyze the relationship of community axes and endemic and exotic species richness to the environment, and group analysis techniques to identify consistent groupings of species and characterize their properties. We found that community variation could be explained by a two-axis ordination. One axis ranged from conifer forest to grassland and was strongly related to precipitation. The second axis ranged from chaparral to grassland and had little relationship to current environmental conditions, suggesting a possible role for successional history. Precipitation and elevation were respectively the largest influences on endemic and exotic richness, followed by Mg2+/ Ca2+. The results also support the idea that long-term precipitation patterns have altered the Mg2+/ Ca2+ ratio via selective leaching, resulting in indirect influences on endemics ( positive) and exotics ( negative) but not affecting the abundances of common species. We discuss implications of these findings for the conservation of the California serpentine flora. C1 USDA Forest Serv, Pacific SW Reg, Vallejo, CA 94592 USA.

In long-lived species, such as pines, it is unclear how soon after germination local adaptation becomes detectable. Here I present results of a 36-year reciprocal transplant experiment using Pinus ponderosa, along with allozyme analyses from the same trees. Using a repeated measures analysis of variance, there is evidence for adaptation to serpentine soils; however, significant differences between source soil types do not become apparent until 20 years after the start of the experiment. Analysis of allozyme data showed no evidence for differentiation between the serpentine and non-serpentine populations. Comparing the performance of families over the course of the experiment found that there was little correlation between performance after 1 or 4 years of growth in the Weld and performance after 36 years. This suggests that short-term transplant experiments may not provide definitive evidence for adaptation to serpentine soils. A literature survey of all transplant studies using pine species growing on and off of serpentine soils found that studies that lasted fewer than 2 years showed no evidence for adaptation.

The three cultivars were crossed with the leaf rust susceptible cultivar 'Thatcher' and approximately 80 backcross (BCl) F-2 families were derived for each cross. The BClF2 families and selected BClF4 lines were tested for seedling and adult plant leaf rust resistance with selected isolates of leaf rust, Puccinia triticina. The segregation and infection type data indicated that Americano 25e had seedling resistance genes Lr3, Lr16, an additional unidentified seedling gene, and one adult plant resistance gene that was neither Lr12 nor Lr13, and did not phenotypically resemble Lr34. Americano 26n was postulated to have genes Lr11 Lr12, Lr13, and Lr14a. Americano 44d appeared to have two possibly unique adult plant leaf rust resistance genes.

TI Genotypic and environmental effects on selenium concentration of broccoli heads grown without supplemental selenium fertilizer SO PLANT BREEDING LA English DT Article DE Brassica oleracea; Italica Group; doubled haploid; chemoprotection ID CANCER; SELENATE; SOILS; SELENOMETHIONINE; PREVENTION; RATS AB Selenium (Se) is an important trace element in human nutrition that is essential to normal health. Broccoli is known to accumulate relatively high concentrations of Se, and there is strong evidence that consumption of Se-enriched broccoli florets decreases cancer risk. In light of the above, this study was conducted to evaluate differences in Se concentration per head and total Se head content for a collection of broccoli hybrids (20) and inbreds (15) grown in field environments without supplemental Se fertilization. Our objectives were to assess the relative importance of genotype vs. environment in affecting Se levels and to determine if Se content is associated with other important horticultural traits. When analysed over three environments, there was a significant genotype effect for Se head concentration with hybrids, but not inbreds, but the environmental effect was about 10 times larger than that for genotype. Total Se content (ng/head) varied significantly among hybrids and inbreds, but as with concentration, environmental effects were also much larger for this trait. Head Se concentrations for hybrids ranged from 52.7 to 84.7 ng/g and total Se accumulation ranged from 563 to 885 ng/head. The same respective traits ranged from 49.3 to 80.0 ng/g and 678 to 876 ng/head for inbreds. There was no correlation between Se head concentration and head dry mass or days from transplant to maturity for either hybrids or inbreds. There was no evidence that Se might be diluted in broccoli heads as mass increases with cultivars that produce dense heads. Results indicate that it should be feasible to combine relatively high Se concentration or content with high head dry matter (DM), a phenotype that broccoli breeders might strive to achieve.

TI Inheritance and allelic relationships of fertility restoration genes for seven new sources of male-sterile cytoplasm in sunflower SO PLANT BREEDING LA English DT Article DE Helianthus annuus; cytoplasmic male-sterility; fertility restoration; hybrid varieties AB The inheritance of fertility restoration of six mitomycin C and streptomycin-induced cytoplasmic male-sterile (cms) mutants and one cms line derived from Native American cultivar PI 432513 in sunflower was evaluated. These seven new ems sources were also compared with the commercially used cms PET1 (Helianthus petiolaris Nutt.) cytoplasm, using USDA inbred lines with restoration genes (Rf(1)) specific for ems PET1 and new restoration lines identified for cms PI 432513. Restoration genes for cms PI 432513 were found in 'Armavir', VNIIMK, P21 and male-fertile (MF) plants of PI 432513. F-2 and F-3 segregation ratios of crosses between cms PI 432513 and these restoration sources indicated a single dominant gene controlled fertility restoration. Progenies of cms PI 432513 testcrossed with F-1's of half-diallel crosses among the respective four homozygous restoration lines and RHA 274 suggested that the restoration genes of RHA 274, VNIIMK; P21 and PI 432513 were at the same locus. Restoration genes from VNIIMK, P21 and PI 432513 satisfactorily restored pollen stainability in the heterozygous condition. A very weak expression of the Rf gene in 'Armavir' was observed in the heterozygous condition. Fertility restoration capability of these genes for the six mutant ems HA 89 and cms HA 89 (in PET1 cytoplasm) was observed. The mutant cms HA 89 lines were also restored completely by RHA 266, RHA 274, RHA 280 and RHA 296, and F-2's segregation ratios indicated single dominant gene control, implying a common cytoplasmic male sterility in all lines. F-1's of half-diallel crosses among RHA 266, RHA 273, RHA 274, RHA 280 and RHA 296 were testcrossed onto the ems lines, and their all MF progenies among lines, except RHA 280, confirmed that fertility restoration was controlled by a single Rf(1) gene locus. The restoration gene in confection line RHA 280, namely Rf(3), was at a different locus than Rf(1) and was equally capable of restoring all the ems lines. Cms HA 89 mutants and cms PI 432513 are in H. annuus cytoplasm, and are agronomically equal in hybrid performance to the cms PET1 used in commercial sunflower hybrids. These new cms lines will provide immediate alternative cms sources for reducing the genetic vulnerability resulting from the exclusive use of the single cms source PET1 in sunflower hybrid production.

TI Large-scale expression profiling and physiological characterization of jasmonic acid-mediated adaptation of barley to salinity stress SO PLANT CELL AND ENVIRONMENT LA English DT Article DE photosynthesis; salt stress ID GENE-EXPRESSION; SALT TOLERANCE; CARBONIC-ANHYDRASE; METHYL JASMONATE; SIGNALING PATHWAYS; ABIOTIC STRESS; ABSCISIC-ACID; DUNALIELLA-TERTIOLECTA; ARABIDOPSIS-THALIANA; DROUGHT STRESS AB Barley (Hordeum vulgare L.) is a salt-tolerant member of the Triticeae. Recent transcriptome studies on salinity stress response in barley revealed regulation of jasmonic acid (JA) biosynthesis and JA-responsive genes by salt stress. From that observation and several other physiological reports, it was hypothesized that JA is involved in the adaptation of barley to salt stress. Here we tested that hypothesis by applying JA to barley plants and observing the physiological responses and transcriptome changes. Photosynthetic and sodium ion accumulation responses were compared after (1) salinity stress, (2) JA treatment and (3) JA pre-treatment followed by salinity stress. The JA-pre-treated salt-stressed plants accumulated strikingly low levels of Na+ in the shoot tissue compared with untreated salt-stressed plants after several days of exposure to stress. In addition, pre-treatment with JA partially alleviated photosynthetic inhibition caused by salinity stress. Expression profiling after a short-term exposure to salinity stress indicated a considerable overlap between genes regulated by salinity stress and JA application. Three JA-regulated genes, arginine decarboxylase, ribulose 1.5-bisphosphate carboxylase/oxygenase (Rubisco) activase and apoplastic invertase are possibly involved in salinity tolerance mediated by JA. This work provides a reference data set for further study of the role of JA in salinity tolerance in barley and other plants species. C1 USDA ARS, US Salin Lab, Riverside, CA 92501 USA.

NOV; ACIDISCABIES; RESISTANCE; DISEASE AB Common scab is a serious disease of potatoes (Solanum tuberosum) and other root and tuber crops, affecting the quality and market value of these crops. The disease is caused by grampositive soil bacteria in the genus Streptomyces. A new common scab-causing streptomycete was isolated from scabby potatoes originating in southeastern Idaho. Research has supported a model of horizontal transfer of pathogenicity determinants among streptomycetes, and the ne strain has hallmarks of the recently characterized Streptomyces pathogenicity island (PAT); it has genes encoding the synthetase for the pathogenicity determinant thaxtomin and for a second pathogenicity factor, tomatinase, although it lacks a third gene characteristic of the Streptomyces PAT, the nec1 gene. The new strain has a unique 16s rDNA gene sequence closely related to those of other pathogenic Streptomyces species. This 16s rDNA sequence was also found in isolates lacking a PAT, suggesting that the new pathogenic strain arose by horizontal transfer of a PAT into a saprophytic streptomycete. Isolates of the new strain are pathogenic on radish and potato, and are more virulent than the S. scabies type strain. In addition to scab lesions on potato tubers, lesions were also seen on underground stems and stolons. This new strain represents additional complexity in the pathogenic strains causing plant disease in the United States. C1 USDA ARS, Vegetable Lab, Beltsville, MD 20705 USA.

Host plant resistance is a promising method of Vw control. Culture-based methods that quantify the pathogen in host tissue often are used for Vw resistance screening. To evaluate the processing time, accuracy, and precision of these methods, 46 clones were planted in a field naturally infested with V dahliae to collect data on visual disease symptoms, pathogen colonization, and yield. In 2002, disease severity explained 43.4% of the variability of yield loss, but the linear relationship between stem colonization and yield loss was not significant. In 2003, stem colonization explained 57.5% of the variability of yield loss, whereas disease severity explained 1.7% of the variability of yield loss. Correlations comparing clone ranks from repeated pathogen measurements indicated that culturing sap from individual stems or bulked stems generated more repeatable clone rankings than culturing dried stems. Clone rankings were more repeatable between years if pathogen measurements were made earlier in the growing season, The results indicate a need to characterize the effect of the environment on the relationship among pathogen population sizes in planta, disease symptoms, and yield loss.

Real-time PCR assays were conducted on the youngest, fully expanded leaf of three cultivars collected bi-weekly from field nurseries between I I April and 19 July 2005. L xyli subsp. xyli infection was detected in leaves collected at all sampling dates, including those from I-month-old plants on I I April. Assays conducted on older, more rapidly growing plants (28 July and 21 October 2005) indicated that leaf position affects assay efficiency. Conventional PCR was less efficient than real-time PCR for detecting L. xyli subsp. xyli in leaf tissue. Real-time PCR was used to rank cultivars for susceptibility to L. xyli subsp. xyli infection based on the relative titer of L. xyli subsp. xyli in leaves of inoculated, 3- and 4-month-old greenhouse-grown plants. The ranking of cultivars by real-time PCR was in close agreement with the ranking determined by tissue-blot enzyme immunoassay performed on tissue from 7- to 9-month-old stalks.

Stem lesions were produced on inoculated seedlings of 12 Eastern forest species following 72 to 76 days of incubation in a containment greenhouse cubicle at 20 degrees C. Chestnut oak (Quercus prinus) and white oak (Q. alba) were followed by northern red oak (Q. rubra) in susceptibility to stem inoculation. Sugar maple (Acer saccharum) and black walnut (Juglans nigra) were more resistant to stem inoculation than most of the oak species tested. R ramorum was isolated on selective medium at distances of up to 8 mm from stem lesion margins. Foliar lesions were observed within 7 days when seedlings were inoculated with 5,000 sporangia/ml followed by incubation at 20 degrees C in a dew chamber. Chestnut oak was followed by tanoak (Lithocarpus densiflorus) and coast live oak (Q. agrifolia) in susceptibility to P ramorum by foliar inoculation. Chestnut oak, an ecologically important species in parts of the Eastern United States, emerged as the most susceptible host tested in both stem and foliar inoculations. The results indicate that, under controlled conditions, P ramorum is able to infect some important Eastern forest species and cause lesions on stems and foliage. It remains to be determined whether infection of these species by P. ramorum would occur under natural conditions. C1 USDA ARS, Foreign Dis Weed Sci Res Unit, Ft Detrick, MD 21702 USA.

SO PLANT DISEASE LA English DT Article ID DAHLIAE RACE-2; TOMATO; PATHOGEN; PLANTS; VE AB Host resistance offers the most cost-effective method of Verticillium wilt control in lettuce (Lactuca sativa). In 2004 and 2005, 107 and 22 lettuce cultivars, respectively, were screened for resistance in a field infested with Verticillium dahliae, and disease progress on resistant and susceptible cultivars was determined. Greenhouse experiments were conducted to evaluate 16 cultivars for resistance to a race I and a race 2 isolate. Significant differences for resistance were observed within cultivated lettuce. In susceptible cultivars, disease levels increased through the season, whereas disease in resistant cultivars remained constant. Resistance in greenhouse tests was dependant upon the race used. Seven cultivars were resistant to race 1, whereas all were susceptible to race 2. Cultivar reactions to race I in greenhouse and field experiments were correlated, indicating the utility of greenhouse evaluations. The identification of resistance in diverse lettuce types is beneficial to the breeding process. However, because of the existence of resistance-breaking race 2 isolates, this resistance may not be durable. Alternatively, targeted releases of race-1-resistant cultivars to fields with only race I pathogen genotypes may extend the life of these cultivars.

Virus isolates associated with the diseased plants were identified using reverse-transcriptase polymerase chain reaction (RT-PCR) to distinguish between Sugarcane mosaic virus (SCMV) and Sorghum mosaic virus (SrMV). No SCMV strain was associated with any diseased plant collected during the survey. RT-PCR-based restriction fragment length polymorphism (RFLP) analysis showed that SrMV strains 1, H, and M were associated with 67, 10, and 2% of the plants with mosaic symptoms, respectively. In previous surveys conducted between 1978 and 1995, over 90% of the plants sampled were infected with SrMV strain H. The remaining plants mostly were infected with SrMV strain 1, except for an occasional sample with SrMV strain M. RT-PCR showed that approximately 13% of the samples collected between 2001 and 2003 were infected with SrMV, but the RFLP banding pattern did not match any described strain. Twelve plants were co-infected by two SrMV strains and two plants by three SrMV strains. No RT-PCR product was produced by either the SCMV- or the SrMV-specific RT-PCR primer set for 8% of the plants showing mosaic symptoms, suggesting that another virus may cause sugarcane mosaic in Louisiana.

TI A method for cellular localization of gene expression via quantitative in situ hybridization in plants SO PLANT JOURNAL LA English DT Article DE confocal laser-scanning microscopy; fluorescence; mRNA in situ hybridization; quantification ID HYPERACCUMULATOR THLASPI-CAERULESCENS; GUARD-CELLS; METAL; RNA; INSITU; COMPARTMENTATION; TRANSCRIPTS; TRANSPORT; PROTEIN; NICKEL AB A quantitative in situ hybridization technique (quantitative whole-mount in situ hybridization, QISH) for plants is described. It employs direct hybridization of fluorescently labelled gene-specific oligonucleotides in large tissue pieces combined with optical sectioning. It dramatically increases the throughput compared with conventional antibody- and microtome-based in situ mRNA hybridization methods, while simultaneously eliminating artefact-prone preparation steps that prevent reliable quantification in conventional methods. The key feature of this technique is the quantification of gene expression using housekeeping genes (cytosolic GAPDH and 18S RNA) as internal standards. This feature enables a correction of varying cytoplasm/vacuole ratios in different cell types, as well as tissue optical effects and non-specific signals. The quantitative nature of the technique allows for analysis of gene expression in response to different environmental conditions, as well as tissue- and age-dependent differences in gene expression patterns. In addition to testing tissue permeabilization, structural preservation, specificity, linearity and tissue optical effects, we verified the reliability of the technique with three Arabidopsis thaliana genes of known function and distribution. These were the rbcL gene for ribulose 1,5-bisphosphate carboxylase, the developmentally related gene SCARECROW (AtSCR) and PHOT-1, a photoreceptor kinase. As expected, rbcL mRNA was found in all photosynthetic cells, while SCR mRNA was detected mainly in bundle sheath cells and PHOT-1 was found predominantly in epidermal and cortical cells of the apical hook of light-grown seedlings. As an application example, QISH was used to measure transcript abundance for a zinc transporter from the ZIP family of transporters in the Zn/Cd hyperaccumulator model plant, Thlaspi caerulescens, and the related non-accumulator Thlaspi arvense. This showed that QISH can be used to compare differences in mRNA levels between cell types, plant growth conditions and plant species. Messenger RNA for the zinc transporter gene ZNT1 was abundant in photosynthetic cells, but not in the epidermal storage cells where metal hyperaccumulation in T. caerulescens occurs. This indicates that ZNT1 does not directly participate in metal hyperaccumulation within the leaf. Growing T. caerulescens with high zinc levels strongly reduced ZNT1 transcript abundance in the spongy mesophyll cells, but less in the other cell types. In T. arvense, ZNT1 mRNA levels were generally much lower, and were furthermore drastically reduced by growth at increased zinc levels, confirming earlier reports regarding ZNT1 regulation in these two Thlaspi species.

To test this hypothesis, a family of transgenic cotton plants (Gossypium hirsutum cv. Coker 312 elite) was produced that over-expressed spinach sucrose-phosphate synthase (SPS) because of its role in regulation of sucrose synthesis in photosynthetic and heterotrophic tissues. A family of 12 independent transgenic lines was characterized in terms of foreign gene insertion, expression of spinach SPS, production of spinach SPS protein, and development of enhanced extractable V (max) SPS activity in leaf and fiber. Lines with the highest V (max) SPS activity were further characterized in terms of carbon partitioning and fiber quality compared to wild-type and transgenic null controls. Leaves of transgenic SPS over-expressing lines showed higher sucrose:starch ratio and partitioning of C-14 to sucrose in preference to starch. In two growth chamber experiments with cool nights, ambient CO2 concentration, and limited light below the canopy, the transgenic line with the highest SPS activity in leaf and fiber had higher fiber micronaire and maturity ratio associated with greater thickness of the cellulosic secondary wall.

Sensitive (S; n = 50) strains did not grow on IMZ above 0.1 mu g mL(-1), while those resistant (R; n = 59) grew >= 0.5 mg L(-1). After amplification of the promoter region of the CYP51 gene, fragments 250, 450, and 750 bp in size were generated. All S strains had a 250 bp product, while among R strains, 47 had a 450 bp product and 12 had a 750 bp product. The 450 bp unit was common among R strains, while the 750 bp unit, reported previously by others, was not. The promoter region of all was identical; variations occurred in the region's transcriptional enhancer unit. S strains with a 250 bp product and R strains with a 750 bp product had one and five copies, respectively, of a 126 bp transcriptional enhancer unit. R strains with a 450 bp product had a unique 199 bp insert within the 126 bp transcriptional enhancer unit with no known sequence correlations (GenBank). Both types of R strains exhibited significantly elevated expression, approximately 10-fold, of the target site CYP51 gene, indicating its overexpression was the mechanism of resistance.

Analytical quality characteristics of packaged fresh-cut watermelon slices from non-treated and 1-methylcyclopropene (1-MCP)- and/or ethylene-treated whole fruit were investigated. Freshly harvested seedless watermelon ('Sugar Heart') were stored 7-14 days in air before exposure to 0, 0.5 or 1.0 mu L L-1 1-MCP for 18 h followed by 5 days exposure to 0 or 10 mu L L-1 ethylene, all at 20 degrees C. Following treatment, fruit were processed into wedge-shaped slices, packaged into rigid trays sealed with a high oxygen transmission rate film overlap and stored 1, 6 or 12 days at 5 degrees C. During storage, fresh-cut watermelon slices from non-treated and 1-MCP- and 1-MCP+ethylene-treated whole fruit maintained similar respiration rates and internal atmospheres of CO2 and O-2 and were of similar quality with total aromatic volatile concentrations decreasing and puncture firmness, soluble solids content (SSC), cut surface pH and color remaining relatively stable. In contrast, fresh-cut slices from fruit treated with ethylene alone had higher respiration rates and modified package atmospheres containing more CO2 and O-2; lower firmness, SSC and chromaticity values; higher pH and an altered volatile profile compared to those of slices from non-treated and 1-MCP- and 1-MCP + ethylene-treated fruit. The 22 most abundant volatiles were various aldehydes, alcohols and ketones. During storage, many individual volatiles decreased in concentration but some increased including (Z)-6-nonen-1-ol, a volatile having a pumpkin-like aroma. The results indicated that low dosage 1-MCP treatments prior to ethylene exposure of whole watermelons prevented ethylene-mediated quality deterioration in fresh-cut slices stored under modified atmosphere conditions at 5 degrees C.

However, public criticism of feed deprivation, based on the perception that it inhumanely increases hunger, has led the poultry industry to ban the practice. Thus far, alternatives have not been demonstrated to ameliorate the increase in hunger that led to the ban on inducing molting by feed deprivation. Incorporating melengestrol acetate (MGA), an orally active progestin, into a balanced layer diet induces molting and increases postmolt egg quality. Hy-Line W-98 hens (n = 60) were randomly assigned to a balanced layer ration (control), a balanced layer ration containing MGA, or a 94% wheat middlings diet (wheat) for 20 d, or were feed deprived for 8 d. Hens were trained to peck a switch to receive a feed reward based on a progressive ratio reinforcement schedule. Motivation of hens to acquire feed was measured as the total number of pecks recorded in 15 min on d 0, 4, 8, 12, 16, and 20. On d 20, abdominal fat pad and digesta-free gizzards were weighed. The number of pecks in the feed-deprived group was greater than controls by d 4 and remained greater at d 8, when these hens were removed from the experiment. Hens in the wheat group that were rewarded with a layer diet pecked more than controls from d 8 to 20. Hens in the MGA group pecked for a reward at the same rate as control hens throughout the experiment. Hens fed the wheat diet had heavier gizzards compared with control and MGA-fed hens. Hens fed MGA had greater abdominal fat pad compared with wheat and control hens. Hens molted using a diet containing MGA have a similar motivation to obtain feed as control hens; therefore, this alternative does not appear to increase hunger. However, hens melted with a wheat middling diet appear to be as motivated to obtain feed as did the feed-deprived hens.

Experiment 1 used 1-d-old male poults that were the progeny of 33-wk-old hens in their second week of lay. Experiment 2 used male poults of the same genetic line from 40-wk-old hens in their eighth week of lay. Poults were fed a standard unmedicated turkey starter diet or the same diet with either a low level (504 g/t) or a high level (1,008 g/t) of yeast extract. Challenged birds were exposed to intermittent cold stress during wk I to 3 and to a respiratory E. coli challenge at I wk of age. In both experiments, BW at wk I was increased by feeding yeast extract. In experiment 1, challenged, control-fed birds had decreased BW at wk 3 and feed conversion was protected by both levels of yeast extract supplementation. In experiment 2, challenge had no effect on control-fed birds; however, yeast extract decreased the BW of challenged birds. In experiment 1, total leukocyte numbers were decreased by challenge of control-fed birds only, and there was no effect of challenge on the heterophil/lymphocyte ratio. In experiment 2, total leukocyte numbers were decreased and the heterophil/lymphocyte ratio was increased in challenged, control-fed birds. Percentage mortality was not affected by challenge in experiment 1; however, in experiment 2, mortality was increased by challenge of control-fed birds and those fed the lower level of yeast extract. These results suggest that hen age should be considered when designing studies to evaluate antibiotic alternatives and in making decisions for incorporating such alternatives into production.

Plasma samples were obtained daily from 10 d of embryogenesis (10E) through 13 d posthatch and also at 17 and 21 d posthatch. A significant increase in plasma insulin was observed with increasing age from 10E to hatch. Plasma glucagon levels remained low until 17E, and then significantly increased approximately 3-fold at hatch, which corresponded with increasing plasma glucose levels during late embryo development. The plasma insulin to glucagon molar ratio of incubation from 14E to 17E ranged from 2 to 4, and was significantly higher than at any other time during incubation. These results indicate that insulin may be an important promoter of chick embryonic growth by the anabolic drive to promote protein deposition. Insulin and glucagon increased after hatch, which may be due to increased feed consumption and increased utilization of carbohydrates as the key energy source, compared with nutrients obtained through lipolysis and proteolysis in the embryos. Plasma triiodothyronine increased 4-fold from 18E to 20E, and thyroxine increased 3-fold from 16E to 19E. Insulin-like growth factor-I and IGF-II peaked at 14E. Insulin-like growth factor-I steadily increased above embryonic levels during the 3 wk of the posthatch period, whereas IGF-II levels steadily declined. These results suggest that IGF-II may be a more important functionary for chick embryonic development than IGF-I, and that IGF-I may be more important than IGF-II after hatch. The profile of metabolic hormones in the present study may help support an understanding of significant changes that occur in embryonic development and posthatch growth in chicks.

Experimental layer diets, which included either a basal control diet or the same diet supplemented with 0.025% PHY and 25hydroxycholecalciferol, were fed from 20 through 58 wk of age. The supplemented diet decreased blood hematocrit values across bird age, inoculation type (sham vs. F-strain M. galliscpticum), and age of inoculation (prelay vs. onset of lay). Phytase- and 25-hydroxycholecalciferol-supplemented diets reduced bird BW in sham-inoculated control birds across bird age and age of inoculation. This effect was not observed in F-strain M. galliscpticum-inoculated birds. Furthermore, across diet (control vs. supplemented) and inoculation type, total plasma protein concentration at 34 wk of age was higher in birds that were inoculated at the onset of lay compared with those inoculated prelay. Diet, inoculation type, and inoculation age had no effect on mortality, reproductive organ histopathological lesion scores, or serum cholesterol and Ca concentrations. In conclusion, throughout lay, the supplementation of commercial layer diets with PHY may lower hematocrit, and inoculation with F-strain M. galliscpticurn prelay or at the onset of lay may ameliorate the depressing effects of dietary PHY and 25-hydroxycholecalciferol supplementation on hen BW.

The new genus can be distinguished from all other Olethreutinae by its unusual male genitalia, with a digitate uncus covered with long hairs and the absence of socii, and its distinctive forewing maculation (i.e., dark brown with scattered iridescent scales). Assignment of the new genus to Grapholitini is provisional based on the general appearance and chaetotaxy of the larva and a feature of the wing venation (i.e., M-2 and M-3 parallel and widely separated at the base). The entire type series was reared from stem galls on lima bean, Phaseolus lunatus L. (Fabaceae).

The purified recombinant AMY hydrolyzed corn and wheat starch granules, respectively, at rates 1.7 and 2.5 times that of GLA under the same reaction conditions. AMY and GLA synergistically enhanced the rate of hydrolysis by similar to 3x for corn and wheat starch granules, compared to the sum of the individual activities. The exo-endo synergism did not change by varying the ratio of the two enzymes when the total concentration was kept constant. A yield of 4% conversion was obtained after 25 min 37 degrees C incubation (1 unit total enzyme, 15 mg raw starch granules, pH 5.3). The temperature stability of the enzyme mixtures was <= 50 degrees C, but the initial rate of hydrolysis continued to increase with higher temperatures. Ca++ enhanced the stability of the free enzymes at 50 degrees C incubation. Inhibition was observed with the addition of 10 mM Fe++ or Cu++, while Mg++ and EDTA had lesser effect.

The present analysis of recent rural development in rural US counties, which focuses on natural amenities as quality of life indicators, supports the creative class thesis. A repetition for urban counties also shows a strong relationship between creative class presence and growth, although natural amenities play a smaller role. However, the results depend on a recast creative class measure, which excludes from the original Florida measure many occupations with low creativity requirements and those involved primarily in economic reproduction. The measure conforms more closely to the concept of creative class and proves to be more highly associated with regional development than the original Florida measure.

Intimate linkage of human and animal health is not a new phenomenon. However, the global scope of contemporary zoonoses has no historical precedent. Indeed, most human infectious diseases classed as emerging are zoonotic, and many of these have spilled over from natural wildlife reservoirs into humans either directly or via domestic or peridomestic animals. Conservation medicine has recently emerged as a meaningful discipline to address the intersection of animal, human, and ecosystem health. Interest in the development of novel vaccines for wildlife encounters important challenges that may prevent progress beyond the conceptual phase. Although notable examples of successful wildlife immunisation programmes exist, depending upon key considerations, vaccination may or may not prove to be effective in the field. When implemented, wildlife vaccination requires a combination of novel zoonosis pathogen management strategies and public education to balance conservation, economic, and public health issues.

However, factors such as temperature and salinity affecting the readings require further quantitative investigation and explanation. Theoretical sensitivities of capacitance sensors to liquid salinity and temperature of porous media were derived and computed using a revised electrical circuit analogue model in conjunction with a dielectric mixing model and a finite element model of Maxwell's equation to compute electrical field distributions. The mixing model estimates the bulk effective complex permittivities of solid-water-air media. The real part of the permittivity values were used in electric field simulations, from which different components of capacitance were calculated via numerical integration for input to the electrical circuit analogue. Circuit resistances representing the dielectric losses were calculated from the complex permittivity of the bulk soil and from the modeled fields. Resonant frequencies from the circuit analogue were used to update frequency-dependent variables in an iterative manner. Simulated resonant frequencies of the capacitance sensor display sensitivities to both temperature and salinity. The gradients in normalized frequency with temperature ranged from negative to positive values as salinity increased from 0 to 10 g L-1. The model development and analyses improved our understanding of processes affecting the temperature and salinity sensitivities of capacitance sensors in general. This study provides a foundation for further work on inference of soil water content under field conditions. C1 ETH, Inst Terr Ecosyst, CH-8092 Zurich, Switzerland.

TI Faecal near infrared reflectance spectroscopy to predict diet quality for sheep SO SMALL RUMINANT RESEARCH LA English DT Article DE sheep; near infrared reflectance spectroscopy; faeces; protein; digestibility ID NIRS EQUATIONS; CATTLE; GOATS AB Faecal near infrared reflectance spectroscopy (NIRS) is a non-invasive method to determine diet quality in herbivores, but has not been reported for sheep (Ovis aries) in US. A diet reference chemistry:faecal near infrared spectra calibration (n = 78) was developed to determine if faecal NIRS can predict diet quality of forage-fed sheep. In 2002 (n = 15) and 2003 (n = 20) mature ewes (55 +/- 2.4 kg) were fed individual diets for 7 days. Diets ranged from 4.3 to 23.5% crude protein (CP) and 52.4 to 75.8% digestible organic matter (DOM) and were composed of various grass, forb and browse components. Daily intake was recorded. Faecal samples were collected on days 6 and 7. CP was determined by micro-Kjeldahl and DOM by an in vivo corrected in sacco technique. Partial least squares (PLS) and stepwise regression (SWR) techniques were used to develop predictive equations. Calibration results for percent dietary CP were: SWR, R-2 = 0.93, SE calibration (SEC) = 1.27 and PLS, R-2 = 0.95, SEC = 1.08. Calibration results for DOM were: SWR, R-2 = 0.78, SEC = 1.58 and PLS, R-2 = 0.80, SEC = 1.51. Equation validation was accomplished by cross validation, predicting an independent validation set, and by predicting day 7 samples with a day 6 derived equation within this study. Validation results indicate acceptable predictive ability. To determine the effect of individual animal variation on faecal NIRS predictions, five ewes were fed different forages in two, 7-day trials. Predicted percent CP and DOM from both trials indicate minimal effect on NIR predicted diet quality due to individual animal variation. Diet quality of forage-fed sheep can be accomplished by faecal NIRS. (c) 2005 Elsevier B.V. All rights reserved. C1 Texas A&M Univ, Dept Rangeland Ecol & Management, College Stn, TX 77845 USA.

Total P sorption capacity (PSC) was measured in Wellsboro (coarse-loamy, mixed, active, mesic Typic Fragiudept) and Oquaga (loamy-skeletal, mixed, superactive, mesic Typic Dystrudept) channery silt loam soils with varying histories of dairy (Bos taurus) and poultry (Gallus domesticus) manure addition. Batch isotherm analyses were conducted, from which Langmuir sorption maxima were estimated using two methods. Sorption maxima were used to determine the total PSC. Soils ranged in total P from 1080 to 2580 mu g g(-1) for dairy fields and 1654 to 11684 mu g g or poultry fields. The total PSC was poorly related to the total P levels in unamended soils (r(2) = 0.42) but increased nonlinearly with total P in poultry and dairy soils (r(2) = 0.85). Total PSC was well correlated to a single-point P sorption index in all soils (r(2) = 0.74). The most accurate predictions of PSC were obtained using a model based on molar amounts of Mehlich-3 Fes Al, and Ca (r(2) = 0.83). When this model was used to calculate the degree of P saturation (DPS), the comparison of DPS with 0.01 M CaC1(2) P showed that at DPS greater than 30%, 0.01 M CaC1(2) P increased rapidly. We conclude that Mehlich-3 Fe, Al, and Ca data can be used to predict PSC and DPS across soils with widely varying manure management histories.

TI Loss of alkaline earth elements by runoff from agricultural watersheds SO SOIL SCIENCE LA English DT Article DE alkaline earth elements; runoff; barium; calcium; magnesium; strontium; agricultural watershed ID NITRATE-NITROGEN; PHOSPHORUS; LAND AB The loss of agricultural chemicals in runoff from agricultural land is a major cause of poor surface water quality in the United State. Scientists (Natural Resources Conservation Service) developed a technique using climatic, hydrologic, and soil survey information to estimate the impact of agricultural watersheds on natural water resources. The objective of this study was to apply this technique on the Wagon Train (WT) watershed to predict loss of alkaline earth elements (calcium [Ca], magnesium [Mg], barium [Ba], and strontium [Sr]) by runoff from soils and to estimate elements loading into WT reservoir. The predicted losses of Ca, Mg, Ba, and Sr by runoff were 67.5, 19.9, 0.17, and 0.05 kg ha(-1) yr(-1) 1, respectively. These data give a total annual loss of 262.1 and 77.1 Mg of Ca and Mg, respectively, for the entire watershed and could be considered as the annual loading for WT reservoir. The total annual loss was 668 kg for Ba and 186 kg for Sr and could represent the annual loading for the reservoir. The predicted Ca, Mg, and Ba concentrations in runoff were in good agreement with those observed in water samples collected weekly from the main stream in the watershed. However, the predicted Sr concentration in runoff was much less than that observed in the stream water. Subsurface seepage into the stream might contribute to the high Sr concentration observed in the stream water.

Previous investigations of the spatial variability in surface soil properties and crop yield in a glacial till landscape in west central Minnesota indicated that wheat (Triticum aestivum) yields were decreased in upper hillslope positions affected by high soil erosion loss. In the present study, soil cores were collected and characterized to indicate the effects of long-term intensive tillage on soil properties as a function of depth and tillage erosion. This study provides quantitative measures of the chemical and physical properties of soil profiles in a landscape subject to prolonged tillage erosion, and compares the properties of soil profiles in areas of differing rates of tillage erosion and an uncultivated hillslope. These comparisons emphasize the influence of soil translocation within the landscape by tillage on soil profile characteristics. Soil profiles in areas subject to soil loss by tillage erosion > 20 Mg ha(-1) year(-1) were characterized by truncated profiles, a shallow depth to the C horizon (mean upper boundary 75 cm from the soil surface), a calcic subsoil and a tilled layer containing similar to 19 g kg(-1) of inorganic carbon. In contrast, profiles in areas of soil accumulation by tillage > 10 Mg ha(-1) year(-1) exhibited thick sola with low inorganic carbon content (mean 3 g kg(-1)) and a large depth to the C horizon (usually > 1.5 m below the soil surface). When compared to areas of soil accumulation, organic carbon, total nitrogen and Olsen-extrac table phosphorus contents measured lower, whereas inorganic carbon content, pH and soil strength measured higher throughout the profile in eroded landscape positions because of the reduced soil organic matter content and the influence of calcic subsoil material. The mean surface soil organic carbon and total nitrogen contents in cultivated areas (regardless of erosion status) were less than half that measured in an uncultivated area, indicating that intensive tillage and cropping has significantly depleted the surface soil organic matter in this landscape. Prolonged intensive tillage and cropping at this site has effectively removed at least 20 cm of soil from the upper hillslope positions. (c) 2006 Elsevier B.V. All rights reserved.

We examined the effects of two tillage practices [conventional till (CT) and no-till (NT)] and five crop rotations [continuous spring wheat (Triticum aestivum L.) (CW), spring wheat-fallow (W-F), spring wheat-lentil (L-ens culinaris Medic.) (W-L), spring wheat-spring wheat-fallow (W-W-F), and spring wheat-pea (Pisum sativum L.)-fallow (W-P-F)] on transient land previously under 10 years of Conservation Reserve Program (CRP) planting on the amount of plant biomass (stems + leaves) returned to the soil from 1998 to 2003 and soil C and N fractions within the surface 20 cm in March 2004. A continued CRP planting was also included as another treatment for comparing soil C and N fractions. The C and N fractions included soil organic C (SOC), soil total N (STN), microbial biomass C and N (MBC and MBN), potential C and N mineralization (PCM and PNM), and NH4-N and NO3-N contents. A field experiment was conducted in a mixture of Scobey clay loam (fine-loamy, mixed, Aridic Argiborolls) and Kevin clay loam (fine, montmorillonitic, Aridic Argiborolls) in Havre, MT, USA. Plant biomass yield varied by crop rotation and year and mean annualized biomass was 45-50% higher in CW and W-F than in W-L. The SOC and PCM were not influenced by treatments. The MBC at 0-5 cm was 26% higher in W-W-F than in W-F. The STN and NO3-N at 5-20 cm and PNM at 0-5 cm were 17-1206% higher in CT with W-L than in other treatments. Similarly, MBN at 0-5 cm was higher in CT with W-L than in other treatments, except in CT with W-F and W-P-F. Reduction in the length of fallow period increased MBC and MBN but the presence of legumes, such as lentil and pea, in the crop rotation increased soil N fractions. Six years of tillage and crop rotation had minor influence on soil C and N storage between croplands and CRP planting but large differences in active soil C and N fractions.

To provide greater resolution among these taxa, a 900-bp intron from a late embryogenesis abundant (LEA)-like gene (IFG8612) was sequenced from 39 pine species, with two or more alleles representing 33 species. Nineteen of 33 species exhibited allelic nonmonphyly in the strict consensus tree, and 10 deviated significantly from allelic monophyly based on topology incongruence tests. Intraspecific nucleotide diversity ranged from 0.0 to 0.0211, and analysis of variance shows that nucleotide diversity was strongly associated (P < 0.0001) with the degree of species monophyly. Although species nonmonophyly complicates phylogenetic interpretations, this nuclear locus offers greater topological support than previously observed for cpDNA or nrITS. Lacking evidence for hybridization, recombination, or imperfect taxonomy, we feel that incomplete lineage sorting remains the best explanation for the polymorphisms shared among species. Depending on the species, coalescent expectations indicate that reciprocal monophyly will be more likely than paraphyly in 1.71 to 24.0 x 10(6) years, and that complete genome-wide coalescence in these species may require up to 76.3 x 10(6) years. The absence of allelic coalescence is a severe constraint in the application of phylogenetic methods in Pinus, and taxa sharing similar life history traits with Pinus are likely to show species nonmonophyly using nuclear markers.

TI Distinguishing terminal monophyletic groups from reticulate taxa: Performance of phenetic, tree-based, and network procedures SO SYSTEMATIC BIOLOGY LA English DT Article DE hybridization; introgression; parsimony; phylogenetic network; principal coordinate analysis; reticulate evolution ID PHYLOGENETIC SYSTEMATICS; CLADISTIC-ANALYSIS; CONSERVATION GENETICS; EXTANT GYMNOSPERMS; SPECIES PROBLEM; SEQUENCE DATA; SEED PLANTS; EVOLUTION; HYBRIDS; RECOMBINATION AB Hybridization is a well-documented, natural phenomenon that is common at low taxonomic levels in the higher plants and other groups. In spite of the obvious potential for gene flow via hybridization to cause reticulation in an evolutionary tree, analytical methods based on a strictly bifurcating model of evolution have frequently been applied to data sets containing taxa known to hybridize in nature. Using simulated data, we evaluated the relative performance of phenetic, tree-based, and network approaches for distinguishing between taxa with known reticulate history and taxa that were true terminal monophyletic groups. In all methods examined, type I error (the erroneous rejection of the null hypothesis that a taxon of interest is not monophyletic) was likely during the early stages of introgressive hybridization. We used the gradual erosion of type I error with continued gene flow as a metric for assessing relative performance. Bifurcating tree-based methods performed poorly, with highly supported, incorrect topologies appearing during some phases of the simulation. Based on our model, we estimate that many thousands of gene flow events may be required in natural systems before reticulate taxa will be reliably detected using tree-based methods of phylogeny reconstruction. We conclude that the use of standard bifurcating tree-based methods to identify terminal monophyletic groups for the purposes of defining or delimiting phylogenetic species, or for prioritizing populations for conservation purposes, is difficult to justify when gene flow between sampled taxa is possible. As an alternative, we explored the use of two network methods. Minimum spanning networks performed worse than most tree-based methods and did not yield topologies that were easily interpretable as phylogenies. The performance of NeighborNet was comparable to parsimony bootstrap analysis. NeighborNet and reverse successive weighting were capable of identifying an ephemeral signature of reticulate evolution during the early stages of introgression by revealing conflicting phylogenetic signal. However, when gene flow was topologically complex, the conflicting phylogenetic signal revealed by these methods resulted in a high probability of type II error (inferring that a monophyletic taxon has a reticulate history). Lastly, we present: a novel application of an existing nonparametric clustering procedure that, when used against a density landscape derived from principal coordinate data, showed superior performance to the tree-based and network procedures tested.

Thirty-six taxa were included; these representing the three morphologically-based subgenera: Pilosella from Eurasia, the circumboreal Hieracium, and Chionoracium from North and South America. Results from the trnT-F and petN-psbM sequence data strongly support the morphologically based classifications. An exception is the placement of H. canadense within subgenus Chionoracium, rather than subgenus Hieracium, which may be due to chloroplast capture. Placement of the genus Andryala within Hieracium subgenus Pilosella is also supported. Additionally, species in subgenus Pilosella targeted for classical biological control are still supported as being in a separate subgenus from native North American taxa.

The Agricultural Research Service (ARS) process, providing bleaching, biopolishing, and shrinkage control by peroxycarboximidic acid oxidation and selective enzyme digestion of wool's scales can cause 10 to 18% strength loss. After ARS processing 3 to 5% fabric strength was regained with application of transglutaminase (TG). The TG reactivity involves the transferase-mediated, acyltransfer reaction between glutamine and lysine with the formation of carboxylamide groups of peptide-bound glutamine in wool keratin. Changes in the specular reflectance Fourier transform infrared spectra of the amide I and II regions attributed to the functional groups involved in the transamidation reaction provided evidence that cross-linking through TG had occured in the fabrics. Optical and fluorescence microscopy showed no influence of TG on the anionic charge imparted by peroxycarboximidic acid oxidation and no influence of TG on the scale smoothing or removal of the enzymatic digestion involved in the ARS process. Confocal microscopy revealed the abundant presence of amine groups in the TG-treated fibers. Thus there is evidence that ARS-processed keratin substrates in the solid state can be self-cross-linked and that they have potential for further reactivity.

Susceptibility to milo disease is conditioned by a single, semi-dominant gene, termed Pc. The susceptible allele (Pc) converts to a resistant form (pc) spontaneously at a gametic frequency of 10(-3) to 10(-4). A high-density genetic map was constructed around the Pc locus using DNA markers, allowing the Pc gene to be delimited to a 0.9 cM region on the short arm of sorghum chromosome 9. Physically, the Pc-region was covered by a single BAC clone. Sequence analysis of this BAC revealed twelve gene candidates. Several of the predicted genes in the region are homologous to disease resistance loci, including one NBS-LRR resistance gene analogue that is present in multiple tandem copies. Analysis of pc isolines derived from Pc/Pc sorghum suggests that one or more members of this NBS-LRR gene family are the Pc genes that condition susceptibility.

More than 35 accessions have been identified with genes for resistance to oat crown and stem rusts, but little is known about their comparative genetic diversity. This study attempted to characterize a structured sample of 369 accessions representing 26 countries and two specific groups with Puccinia coronata avenae (Pc) and Puccinia graminis avenae (Pg) resistance genes using microsatellite (SSR) markers. Screening of 230 SSR primer pairs developed from other major crop species yielded 26 informative primer pairs for this characterization. These 26 primer pairs were applied to screen all the samples and 125 detected alleles were scored for each accession. Analyses of the SSR data showed the effectiveness of the stratified sampling applied in capturing country-wise SSR variation. The frequencies of polymorphic alleles ranged from 0.01 to 0.99 and averaged 0.28. More than 90% of the SSR variation resided within accessions of a country. Accessions from Greece, Liberia, and Italy were genetically most diverse, while accessions from Egypt, Georgia, Ethiopia, Gibraltar, and Kenya were most distinct. Seven major clusters were identified, each consisting of accessions from multiple countries and specific groups, and these clusters were not well congruent with geographic origins. Accessions with Pc and Pg genes had similar levels of SSR variation, did not appear to cluster together, and were not associated with the other representative accessions. These SSR patterns are significant for understanding the progenitor species of cultivated oat, managing A. sterilis germplasm, and exploring new sources of genes for oat improvement.

Over a period of 5 years, Cryptosporidium was identified in the stools of 58 of 157 children prospectively followed from birth in an urban slum (favela) in northeast Brazil. Forty isolates were available for quantification and 42 for speciation (24 Cryptosporidium hominis and 18 C. parvum). Children with C. hominis shed significantly more oocysts/ml of stool (3.5 X 10(6) vs. 1.7 x 10(6) per ml; P = 0.001), and oocyst counts were higher among symptomatic children (P = 0.002). Heavier C. parvum shedding was significantly associated with symptoms (P = 0.004), and symptomatic C. parvum-infected children were significantly more likely than asymptomatic children to be lactoferrin-positive (P = 0.004). Height-for-age (HAZ) Z-scores showed significant declines within 3 months of infection for children infected with either C. hominis (P = 0.028) or C. parvum (P = 0.001). However, in the 3-6 month period following infection, only C. hominis-infected children continued to demonstrate declining HAZ score and asymptomatic children showed even greater decline (P = 0.01). Cryptosporidium hominis is more common than C. parvum in favela children and is associated with heavier infections and greater growth shortfalls, even in the absence of symptoms.

Dyko and Sutton or Diplodia scrobiculata de Wet, Slippers and Wingfield results in SIR or systemic induced susceptibility (SIS) to subsequent colonization by S. sapinea. Induction at the stem base resulted in significant (P < 0.01) SIR in the upper stem, and induction in the upper stem resulted in significant (P < 0.05) SIR at the stem base, indicating that SIR is bidirectional in Austrian pine. However, inoculation at the stem base resulted in significant (P < 0.01) SIS in shoot tips, demonstrating that, in the same host species, the expression of resistance can be organ-dependent, resulting in either SIR or SIS depending on the site of challenge infection. Systemic induced resistance in the stem was associated with induced lignification, supporting a potential role for this defense mechanism in disease resistance. Systemic induced susceptibility has been documented before, but this is the first demonstration of organ-dependent expression of both SIR and SIS in a tree or any other plant.

We have previously shown that nocturnal sap flow accounts for up to 28% of total daily transpiration in woody species growing in a nutrient-poor Brazilian Cerrado ecosystem. In the present study, we assessed the effect of increased nutrient supply on nocturnal transpiration in three dominant Cerrado tree species to explore the hypothesis that, in nutrient-poor systems, continued transpiration at night may enhance delivery of nutrients to root-absorbing surfaces. We compared nocturnal transpiration of trees growing in unfertilized plots and plots to which nitrogen (N) and phosphorus (P) had been added twice yearly from 1998 to 2005. Three independent indicators of nocturnal transpiration were evaluated: sap flow in terminal branches, stomatal conductance (g(s)), and disequilibrium in water potential between covered and exposed leaves (Delta Psi(L)). In the unfertilized trees, about 25% of the total daily sap flow occurred at night. Nocturnal sap flow was consistently lower in the N- and P-fertilized trees, significantly so in trees in the N treatment. Similarly, nocturnal g(s) was consistently lower in fertilized trees than in unfertilized trees where it sometimes reached values of 150 mmol m(-2) s(-1) by the end of the dark period. Predawn g(s) and the percentage of nocturnal sap flow were linearly related. Nocturnal Delta Psi(L) was significantly greater in the unfertilized trees than in N- and P-fertilized trees. The absolute magnitude of Delta Psi(L) increased linearly with the percentage of nocturnal sap flow. These results are consistent with the idea that enhancing nutrient uptake by allowing additional transpiration to occur at night when evaporative demand is lower may avoid excessive dehydration associated with increased stomatal opening during the day when evaporative demand is high.

This study near Brookings, SD, evaluated the effect of crop sequence and tillage on seedling emergence of common sunflower across years. In the third and fourth years of the study, seedling density was sevenfold greater after 2 yr of soybean with tillage compared with a 2-yr sequence of canola and winter wheat with no-till. Apparently, canola and winter wheat enhanced the natural decline of common sunflower seed density in soil, leading to fewer seedlings in following years. In the first year of the study, tillage increased seedling emergence of common sunflower compared with no-till; seedlings rarely emerged in canola or winter wheat. Most seedlings of common sunflower emerged in May, with more than 90% of seedlings emerging between May 7 and June 4. Cool-season crops grown with no-till may affect weed seed survival in soil in the western Corn Belt. C1 USDA ARS, Brookings, SD 57006 USA.

Glyphosate (0.86 kg ae/ha) or glufosinate (0.47 kg ai/ha) were applied alone over the top of glyphosate- or glufosinate-resistant cotton early POST (EPOST) followed by (fb) late POST (LPOST) fb one of the herbicides applied either alone or with a residual herbicide at LAYBY. Glyphosate- and glufosinate-based treatments were applied only to glyphosate- and glufosinate-resistant cotton, respectively. Residual herbicides evaluated included prometryn (1.12 kg ai/ ha), fluometuron (1.12 kg ai/ha), diuron (1.12 kg ai/ha), oxyfluorfen (1.12 kg ai/ha), pendimethalin (1.0 kg ai/ha), prometryn + trifloxysulfuron (1.33 kg ai/ha + 12 g ai/ha), or linuron + diuron (0.56 + 0.56 kg ai/ha). Glyphosate-and glufosinate-based weed management systems with and without residual LAYBY herbicides resulted in little to no injury to cotton. Three applications of glyphosate or glufosinate alone provided better full-season control of most species when compared to two applications of either herbicide. The addition of a residual herbicide to glyphosate or glufosinate at LAYBY did not improve cotton yields, but did improve overall control of barnyardgrass and yellow nutsedge and reduced weed dry biomass present at time of cotton harvest when compared to three applications of glyphosate or glufosinate alone.

The assays were based on germination of johnsongrass pollen in media supplemented with clethodim. Two different methods were used to evaluate pollen germination-a visual assessment and a spectrophotometric assay. The response of pollen to the germination media was linear for 16 h. At 6 h after treatment, absorbance at 500 nm was nearly 0.5; consequently, 6 h was chosen to conduct the pollen assays using the spectrophotometer. Both assessment methods differentiated the susceptible (S) and resistant (R) biotypes. Pollen from the susceptible biotype of johnsongrass was strongly inhibited by increasing concentrations of clethodim, with a GR(50) of 25.8 +/- 0.6 (SE) mu M and GR(50) of 16.4 +/- 1.7 (SE) mu M clethodim by visual assessment and spectrophotometric assessment, respectively. Minimum R/S values were > 3.9 by visual assessment and > 6.1 by spectrophoto metric assessment. ACCase target-site resistance is expressed in johnsongrass pollen.

Potatoes were injured and exhibited chlorosis and stunted growth after halosulfuron applications of 18, 26, and 35 g/ha. Potato height was reduced 33 and 20% in late May by halosulfuron at 18 or 26 g/ha in 2004 and 2005, respectively. Halosulfuron applied alone failed to control hairy nightshade and large crabgrass. Total tuber yield and U.S. no. 1 yield were reduced 10% in halosulfuron-treated plots because of poor weed control and possibly herbicide injury. Tank-mixing rimsulfuron with halosulfaron improved control of hairy nightshade and large crabgrass and increased potato yield. Tank-mixing EPTC at 2 kg/ha with halosulfuron improved early-season hairy nightshade control, but weed control was poor at row closure. Rimsulfuron applied alone at 18 or 26 g/ha controlled hairy nightshade and large crabgrass without potato injury and resulted in the greatest potato yields.

Two sulfonylurea herbicides, chlorsulfuron and metsulfuron-methyl, were evaluated for their effects on meadow foxtail biomass. Both herbicides were applied at four doses, 0.035, 0.070, 0.105, and 0.140 kg ai/ha, together with a control at each of two sites in October 2003. Treatments were replicated four times at each site and arranged in a randomized complete block design and sampled in July 2004 and 2005. Meadow foxtail biomass depended on site (P = 0.001) or year (P = 0.001), but not herbicide treatment (P = 0.182). No biomass production losses resulted from applying up to 0.14 kg/ha of either chlorsulfuron or metsulfuron-methyl on meadow foxtail, even in relatively high-pH soils.

Treatments included halosulfuron, ethalfluralin, and sulfentrazone alone; halosulfuron in tank mixtures with bensulide, clomazone, ethalfluralin, and naptalam; and a tank mixture of naptalam and bensulide. Sulfentrazone applied at 224 g ai/ha to watermelon severely reduced spinach emergence, but did not reduce emergence of broccoli, cabbage, or wheat. Residues of sulfentrazone applied to watermelon at 450 g/ha stunted growth of broccoli and cabbage and was the only treatment that reduced wheat stand. Injury to broccoli, cabbage, and spinach increased as the halosulfuron rate increased. Ethalfluralin did not reduce stand or cause injury to any of the four rotational crops. Naptalam plus bensulide did not reduce stand of the four crops and caused either slight or no injury. Residues of sulfentrazone and halosulfuron can injure vegetables following crops in which these herbicides are used, and caution should be taken particularly with spinach, broccoli, and cabbage in this respect.

Spring applications of 1.12 kg/ha S-metolachlor, 0.027 kg/ha halosulfuron, 0.28 kg/ha sulfentrazone, and 1.12 kg/ha S-metolachlor plus 0.027 kg/ha halosulfuron were made under LDPE mulch in March of each year and included a nontreated control. After removal of the spring crop, vegetables were planted the following August. Seeded and transplanted squash, seeded cucumber, transplanted eggplant, and transplanted cabbage were evaluated. Injury to eggplant, cucumber, and transplanted and seeded squash ranged from 8 to 16% for halosulfuron, sulfentrazone, and S-metolachlor plus halosulfuron in 2002, but no injury was observed in 2005. Cabbage injury was less than 5% for any herbicide treatment either year. There were no differences for cabbage biomass for three harvests for any herbicide treatment relative to the nontreated control. Vine length for cucumber and transplanted squash was significantly reduced by sulfentrazone relative to the nontreated control. Eggplant yield for the first harvest was significantly reduced by sulfentrazone as compared with the nontreated control in 2002 but not in 2005. To avoid injury to rotational crops, growers should read all herbicide labels when considering spring herbicide applications under LDPE mulch when autumn vegetable plantings are part of their production scheme to ensure successful crop production.

The research goals were (1) to determine whether such between-row mowing systems adequately controlled weeds and prevented grain yield loss in other competitive field crops, such as no-till grain sorghum, and (2) to compare broadcast herbicide treatments with between-row mowing systems. PRE atrazine plus dimethenamid at relative rates of 0.75 x and 1 x (where 1 x = 1.7 plus 1.3 kg ai/ha, respectively) were band-applied over rows shortly after planting followed by two between-row mowings close to the soil surface. In 2 of 3 yr in Missouri, this system controlled giant foxtail and common waterhemp as well as broadcast herbicides in no-till sorghum. In 2 of 3 yr, between-row mowing systems also prevented yield loss in no-till sorghum as well as both broadcast herbicides at the same rates and the weed-free check.

The mean SDImax of the 40 hemlock-spruce stands in southeast Alaska was 619. Individually, none of the stand or site factors examined accounted for >30% of the variability observed in SDImax when all 40 stands were analyzed together. Although the spruce proportion of total stand basal area of most stands increased over time and the hemlock proportion of total stand basal area of most stands decreased over time, SDImax was not related to species proportion or changes in species proportion over time.

TI Understanding and defining mortality in western conifer forests SO WESTERN JOURNAL OF APPLIED FORESTRY LA English DT Review DE wildfire damage; mortality models; bark beetles; root disease; tree physiology; tree death; cambial death; delayed mortality ID INDIVIDUAL-TREE MORTALITY; MOUNTAIN PINE-BEETLE; ECTOMYCORRHIZAL FUNGAL COMMUNITY; FIRE-CAUSED MORTALITY; FINE-ROOT BIOMASS; PONDEROSA PINE; LODGEPOLE PINE; DOUGLAS-FIR; POSTFIRE SURVIVAL; INLAND NORTHWEST AB Tree mortality in western conifer forests is a complex process involving several related factors. Conifer mortality tends to be more common in high-elevation forests where stress from weather, insects, and disease result in higher rates of mortality and in the drier interior forests where mortality from fire, insects, and disease are common. Immediate mortality from fire damage may be obvious, but currently there is considerable controversy about labeling fire-injured green trees as dead that have a high probability of experiencing delayed mortality. Trees die when carbohydrates used in respiration exceed those produced in photosynthesis or water movement is impaired, the tree desiccates, and photosynthesis ceases. Immediate or delayed tree mortality may be directly due to biotic or abiotic causes and may be affected by previous damage, current condition (vigor), and attack by secondary agents such as bark beetles. A particular pathogen or insect usually attacks, damages, or kills only one portion of a tree. Trees that are damaged or attacked by pests and expected to have a dead or nonfunctional root system or a nonfunctional stem within 5 years may be considered either dead or death is imminent. Numerous studies have produced logistic regression equations or other statistical models to help determine probability of tree survival. We define and propose that a "dead tree" designation is justified for most species when at least three of the four quadrants from around the base of the root collar has cambium, inner bark, or phloem that are discolored and dead. For large ponderosa pines, a dead tree has all four quadrants with dead cambium. C1 USDA Forest Serv, Portland, OR 97208 USA.

TI Helicopter logging productivity on harvesting operations in southeast Alaska, using ecologically based silvicultural prescriptions SO WESTERN JOURNAL OF APPLIED FORESTRY LA English DT Article DE logging costs; partial cut; yarding; Tongass AB This study examines production rates and costs for felling and helicopter yarding on eight units harvested in accordance with ecologically based silvicultural prescriptions in southeast Alaska. The prescriptions included harvesting to create gaps, harvesting to leave trees in clumps, individual tree selection, and combinations of these treatments. In combination, the treatments represented five levels of basal area (BA) retention. The levels of retention had irregular spatial arrangements caused by gaps and clumps that ranged from 0% retention (clearcut) to 75% of BA retained. Turn time (TT), as adjusted to a standardized distance, and turn weight were used as the basis for estimating productivity. There were statistically significant differences in adjusted TT, depending on the treatment. Areas with higher levels of removal tended to have lower adjusted TTs. With the exception of one unit with a short yarding distance, average turn weights increased as levels of retention decreased. Weighted average cost per thousand board feet (mbf) harvested was $322. The cost per mbf for cutting and yarding together ranged from $305 to $353. C1 USDA Forest Serv, Wrangell, AK 99929 USA.

Bagging treatments and hand-pollination treatments showed that Penstemon scariosus var. albifluvis has a mixed mating system: while some seeds and fruits are produced through self-pollination (both autogamy and geitonogamy), significantly more are produced when flowers are cross-pollinated. The primary flower visitors, and likely pollinators, were several species of native twig- and ground-nesting bees in the families Apidae, Halictidae, and Megachilidae. We found no differences in fruit or seed production between open-pollinated controls and hand-outcrossed flowers, suggesting that pollinator visits were sufficient to maximize female reproductive success. Management plans to conserve White River penstemon must recognize that full reproductive success of this rare plant taxon relies on a suite of pollinating bees, and that the species richness and abundances of bee visitors should be maintained.

Forest managers need detailed quantification of the effects of logging and other management practices on wintering habitats needed by Wild Turkeys and other wildlife. Therefore, we examined winter habitat selection patterns within ponderosa pine (Punts ponderosa) forests and determined factors associated with use of farmsteads by Merriarn s turkeys in the southern Black Hills, South Dakota. We radio-marked 86 female Merriam's turkeys (70 adults and 16 yearlings) and monitored them during winter (1 December-31 March), 2001-2004. Female Wild Turkeys used recently burned pine forest less than expected but selected farmsteads and stands of mature ponderosa pine (< 70% overstory canopy cover, > 22.9 cm diameter at breast height [DBH] trees) for foraging sites. Within forests, female Wild Turkeys selected foraging sites with less understory vegetation and visual obstruction, and larger-diameter ponderosa pine. Ponderosa pine seed abundance varied among years, and pine seeds were most abundant in stands of 30-35 cm DBH with basal area of 22-28 m(2) center dot ha(-1). Abundance of pine seeds may have influenced use of farmsteads by Wild Turkeys, more so than ambient temperatures or snow depth. In the southern Black Hills, management should emphasize open- to mid-canopy and mature-structural-stage pine stands, where seed production was greatest. During winters when mast from pine is unavailable, farmsteads likely provide nutritional supplementation and may be important for maintaining Merriam's turkey populations.

Roxb. syn. Triadica sebifera (L.) Small), an invasive tree species in the southeastern United States, were subjected to extractions and degradative chemical analyses in an effort to better understand the mechanism(s) by which this tree species aggressively competes against native vegetation, and also to facilitate utilization efforts. Analysis of the wood extractives by FTIR spectroscopy showed functionalities analogous to those in hydrolyzable tannins, which appeared to be abundant in the bark; as expected, the seeds had a high wax/oil content (43.1%). Compared to other fast-growing hardwoods, the holocellulose content for the Chinese tallow tree wood was somewhat higher (83.3%). The alpha-cellulose (48.3%) and Mason lignin (20.3%) contents were found to be similar to those for most native North American hardwoods. Results suggest that Chinese tallow tree wood utilization along with commercial wood species should not present any significant processing problems related to the extractives or cell-wall chemistry.

MFA was determined at 1.4, 4.6, 7.6, 10.7, and 13.7 m up the stem of 59 trees, representing five physiographic regions. A nonlinear mixed-effects model was developed to test for regional differences in the initial value of MFA, the rate at which MFA changes with ring number from pith, and the lower bound of MFA achieved. Our results suggest that the parameters of interest differ significantly by region. It was found that MFA differs significantly between the South Atlantic, Gulf, and Hilly regions, compared to the North Atlantic and Piedmont regions, The initial value of MFA was found to be smaller in the Piedmont compared to all other regions. Similarly, the rate at which MFA changes with ring number was found to be significantly smaller in the North Atlantic and Piedmont regions. A test of the lower bound of MFA indicates that the Piedmont region has a significantly larger lower asymptote. These results combined indicate that overall, MFA values are larger in the North Atlantic and Piedmont regions. C1 Univ Georgia, Warnell Sch Forest Resources, Athens, GA 30602 USA.

Maythorpe and Golden Promise SO BMC GENOMICS LA English DT Article ID SINGLE-FEATURE POLYMORPHISMS; SALT-TOLERANCE; SALINITY STRESS; OLIGONUCLEOTIDE ARRAYS; ARABIDOPSIS; GROWTH; GENE; ASSOCIATION; ADAPTATION; REGULATOR AB Background: Golden Promise is a salt-tolerant spring barley closely related to Maythorpe. Salt tolerance in Golden Promise has been attributed to a single mutation at the Ari-e locus (on 5H) resulting from irradiation of Maythorpe. Golden Promise accumulates lower shoot Na+ compared to Maythorpe when growing under saline conditions. This study focused on elucidating the genetic basis and mechanisms involved in this difference. Results: The level of polymorphism between the two genotypes was explored using the Barley1 GeneChip for single feature polymorphisms (SFPs) and an oligonucleotide pool assay for single nucleotide polymorphisms (SNPs). Polymorphism analyses revealed three haplotype blocks spanning 6.4 cM on chromosome 1H, 23.7 cM on chromosome 4H and 3.0 cM on 5H. The Barley1 GeneChip was used to examine transcript abundance in different tissues and stages during development. Several genes within the polymorphic haplotype blocks were differentially regulated. Additionally, a more global difference in the jasmonic acid pathway regulation was detected between the two genotypes. Conclusion: The results confirm that Golden Promise and Maythorpe are genetically very closely related but establish that they are not isogenic, as previously reported, due to three polymorphic haplotype blocks. Transcriptome analysis indicates that the response of the two genotypes to salinity stress is quite different. Additionally, the response to salinity stress in the roots and shoot tissue is strikingly different. C1 Univ Calif Riverside, Dept Bot & Plant Sci, Riverside, CA 92521 USA.

TI Carbon sequestration in the US forest sector from 1990 to 2010 SO FOREST ECOLOGY AND MANAGEMENT LA English DT Article DE carbon budget; forest ecosystem; carbon sink; carbon sequestration; land use change ID ANNUAL NET FLUX; UNITED-STATES; LAND-USE; NORTHERN-HEMISPHERE; TEMPERATE FORESTS; INVENTORY DATA; WOODY BIOMASS; CO2 SOURCES; SINKS; MANAGEMENT AB Forest inventory data supplemented with data from intensive research sites and models were used to estimate carbon stocks and sequestration rates in U.S. forests, including effects of land use change. Data on the production of wood products and emission from decomposition were used to estimate carbon stocks and sequestration rates in wood products and landfills. From 1990 through 2005, the forest sector (including forests and wood products) sequestered an average 162 Tg C year(-1). In 2005, 49% of the total forest sector sequestration was in live and dead trees, 27% was in wood products in landfills, with the remainder in down dead wood, wood products in use, and forest floor and soil. The pools with the largest carbon stocks were not the same as those with the largest sequestration rates, except for the tree pool. For example, landfilled wood products comprise only 3% of total stocks but account for 27% of carbon sequestration. Conversely, forest soils comprise 48% of total stocks but account for only 2% of carbon sequestration. For the tree pool, the spatial pattern of carbon stocks was dissimilar to that of carbon flux. On an area basis, tree carbon stocks were highest in the Pacific Northwest, while changes were generally greatest in the upper Midwest and the Northeast. Net carbon sequestration in the forest sector in 2005 offset 10% of U.S. CO(2) emissions. In the near future, we project that U.S. forests will continue to sequester carbon at a rate similar to that in recent years. Based on a comparison of our estimates to a compilation of land-based estimates of non-forest carbon sinks from the literature, we estimate that the conterminous U.S. annually sequesters 149-330 Tg C year(-1). Forests, urban trees, and wood products are responsible for 65-91% of this sink. Published by Elsevier B.V. C1 US Forest Serv, USDA, Durham, NH 03824 USA.

The first two SVD modes were analyzed. The two leading SVD modes account for 43% of the squared covariance between spring soil moisture and summer precipitation. Their corresponding components explain 14% of the soil moisture variance and 19% of the precipitation variance, respectively, which is larger than that contributed by tropical Pacific sea-surface temperatures (SSTs). The temporal correlations between the two expansion coefficients of each SVD mode are 0.83 and 0.88, respectively, indicating a significant association between spring soil moisture variation and summer precipitation variability. Both positive and negative cross-correlations exist over different regions of the United States in the two modes. Linear regression relates surface relative humidity and surface air temperature to the soil moisture SVD time series. The patterns revealed by the SVD analysis show where the local soil moisture-precipitation coupling contributes to the model's simulation of precipitation.

Runoff, soil water and sediment data, together with weather information, were collected on an hourly basis at the study site. WEPP was first applied to simulate transient surface runoff, soil water and erosion. Two important input parameters, the biomass energy ratio for crop and the effective hydraulic conductivity of surface soil, were calibrated using field-observed runoff, soil water, erosion and plant biomass data. The calibrated model was then used to simulate the hydrologic and erosion impacts of three typical crop rotations, thereby to evaluate their abilities in reducing surface runoff and sediment yield. Results indicated that, with the definition of a restrictive layer at the bottom of the soil profile and the calibration of the two crucial model parameters, WEPP could adequately account for the water balance for the modeled experimental plot. For the study area, continuous corn with a conservation practice that delayed primary and secondary tillages produced tow surface runoff and soil erosion, from both field observation and WEPP modeling. However, this mono-cultural practice may lead to accelerated soil-quality degradation. On the other hand, a four-year-rotation, corn-wheat-alfalfa-alfalfa, was predicted to substantially reduce soil erosion and has potential to become a sustainable cropping system under the pedo-climatic settings of the study area.

TI TaqMan real-time polymerase chain reaction assay for rapid detection of Flavobacterium columnare SO AQUACULTURE RESEARCH LA English DT Article DE Flavobacterium columnare; real-time polymerase chain reaction ID CATFISH ICTALURUS-PUNCTATUS; CHANNEL CATFISH; EDWARDSIELLA-ICTALURI; FISH; PCR; PATHOGEN; PRODUCT; DISEASE; WATER; WARM AB Flavobacterium columnare is a ubiquitous Gram-negative bacterium that causes columnaris disease in a wide variety of fish worldwide. Timely detection of this bacterium is important to prevent its spreading and to reduce the economic loss to fish farmers. We developed a TaqMan-based real-time polymerase chain reaction (PCR) targeting a 113 bp nucleotide region of the chondroitin AC lyase gene of F. columnare G(4). Specificity of the assay evaluated with 20 isolates of F. columnare and 15 other taxonomically or ecologically related bacteria revealed that the primers and probe were 100% specific for detection of F. columnare. The sensitivity limit of detection of F. columnare in pure cultures, over a range of dilutions [3.1 x 10(0)-3.1 x 10(6) colony-forming units (CFU) mL(-1)], was observed to be similar to 3 bacterial cells. The lowest limit of detection in nucleic acids from pure culture of F. columnare was 5.4 fg and the assay was linear with the log of amount of nucleic acid (R-2=0.994) over that range (5.4 ng-5.4 fg). In tissues (blood, gills and kidney) of F. columnare experimentally infected fish, the bacterial numbers measured by TaqMan real-time PCR ranged from 3.4 x 10(0) to 9.5 x 10(5) CFU mL(-1). In both F. columnare experimentally infected and spiked samples, positive PCR results were confirmed by bacteriological culture with 100% agreement. The TaqMan real-time PCR developed in this study is specific, sensitive and reproducible for the detection and quantitation of F. columnare in infected fish.

TI Bench-scale fluidized-bed pyrolysis of switchgrass for bio-oil production SO INDUSTRIAL & ENGINEERING CHEMISTRY RESEARCH LA English DT Article ID BIOMASS; PRETREATMENT AB The U.S. biomass initiative is counting on lignocellulosic conversion to boost the quantities of biofuels currently produced from starches in order to achieve much needed energy security in the future. However, with current challenges in fermentation of lignocellulosic material to ethanol, other methods of converting biomass to usable energy have received consideration nationally. One thermochemical technique, fast pyrolysis, is being considered by the Agricultural Research Service (ARS) researchers of the USDA for processing energy crops such as switchgrass and other agricultural residues, e.g., barley hulls and alfalfa stems for bio-oil (pyrolysis oil or pyrolysis liquids) production. A 2.5 kg/h biomass fast pyrolyzer has been developed at ARS and tested for switchgrass conversion. The unit has provided useful data such as energy requirements and product yields that can be used as design parameters for larger systems based on the processing of perennial energy crops. Bio-oil yields greater than 60% by mass have been demonstrated for switchgrass, with energy conversion efficiencies ranging from 52 to 81%. The results show that char yielded would suffice in providing all the energy required for the endothermic pyrolysis reaction process. The composition of the noncondensable gas produced has been initially characterized. Initial mass and energy balances have been calculated based on this system, yielding useful parameters for future economic and design studies.

The current predominant method of analysis is too expensive and cumbersome, and comprehensive two-dimensional GC coupled to time-of-flight mass spectrometry (GC x GC-TOF-MS) has the potential to lower the costs and speed analysis of PCDD/Fs. In this study, GC x GC-TOF parameters were evaluated and optimized to yield complete separation of the 17 most important PCDD/F congeners from polychlorinated biphenyls (PCBs) interferences, and to attain the lowest detection limits. The optimization study entailed evaluation of oven temperature programs, column flow rates, ion source temperatures, electron ionization energy, data acquisition rate, and various GC x GC parameters, including modulation period, modulator temperature offset and hot pulse duration. After optimization, all 17 PCDD/Fs were separated in < 60 min, and in particular, the critical pair of 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) and pentachlorchiphenyl congener CB126 did not co-elute chromatographically. Accurate identification and determination of all analytes could be made using their deconvoluted full mass spectra. In GC x GC, the modulation period and start time were the most important factors that affected sensitivity and selectivity for the analysis of the PCDD/Fs. The modulation period should be <= 4 s to preserve separations achieved in one-dimensional GC, and the modulation start time was important to achieve one large slice and two smaller symmetrical slices of TCDD to maximize its detection sensitivity. After optimization, the method could identify 0.25 pg of TCDD with standard injection from its full mass spectrum. (c) 2007 Elsevier B.V. All rights reserved.

To discern effects of land use, we focus on resolving landslide density relationships with forest cover. We account for topographic variability between sites and landslide detection bias in air photo mapping. Even so, for sites in the Oregon Coast Range, we find great variability in the ratios of landslide density in forest classes among sites. We present strategies for subsampling available data to quantify this variability. For these data, we find that older forests, when sampled over tens of square kilometers, commonly exhibited the highest landslide densities but over hundreds of square kilometers always exhibited the lowest densities, averaging 30% of that in recently harvested areas and 79% of that in younger, managed forests.

TI Simple, rapid, and inexpensive cleanup method for quantitation of aflatoxins in important agricultural products by HPLC SO JOURNAL OF AGRICULTURAL AND FOOD CHEMISTRY LA English DT Article DE aflatoxin analysis; cleanup minicolumn; Florisil; HPLC; agricultural commodities ID LIQUID-CHROMATOGRAPHIC DETERMINATION; GREEN COFFEE; PHOTOCHEMICAL DERIVATIZATION; FLUORESCENCE DETECTION; PEANUT BUTTER; COLUMN; FLORISIL; CORN; FOOD AB A chemical cleanup procedure for low-level quantitative determination of aflatoxins in major economically important agricultural commodities using HPLC has been developed. Aflatoxins were extracted from a ground sample with MeOH/H2O (80:20, v/v), and after a cleanup step on a minicolumn packed with Florisil, aflatoxins were quantified by HPLC equipped with a C-18 column, a photochemical reactor, and a fluorescence detector. Water/MeOH (63:37, v/v) served as the mobile phase. Recoveries of aflatoxins B-1, B-2, G(1), and G(2) from peanuts spiked at 5, 1.7, 5, and 1.7 ng/g were 89.5 +/- 2.2, 94.7 +/- 2.5, 90.4 +/- 1.0, and 98.2 +/- 1.1, respectively (mean +/- SD, %, n = 3). Similar recoveries, precision, and accuracy were achieved for corn, brown and white rice, cottonseed, almonds, Brazil nuts, pistachios, walnuts, and hazelnuts. The quantitation limits for aflatoxins in peanuts were 50 pg/g for aflatoxin B-1 and 17 pg/g for aflatoxin B-2. The minimal cost of the minicolumn allows for substantial savings compared with available commercial aflatoxin cleanup devices. C1 USDA, ARS, Natl Peanut Res Lab, Dawson, GA 39842 USA.

TI Caffedymine from cocoa has COX inhibitory activity suppressing the expression of a platelet activation marker, P-selectin SO JOURNAL OF AGRICULTURAL AND FOOD CHEMISTRY LA English DT Article DE caffedymine; COX inhibitor; thromboxane B2; P-selectin; platelet-leukocyte interactions ID FLOW-CYTOMETRIC ANALYSIS; IN-VITRO; TYRAMINE N-(HYDROXYCINNAMOYL)TRANSFERASE; N-COUMAROYLDOPAMINE; CD62P EXPRESSION; CAFFEOYLDOPAMINE; CYCLOOXYGENASE-2; AGGREGATION; CLONING; TXA(2) AB Caffedymine (N-caffeoyldopamine) is a clovamide-type phenylpropenoic acid amide found in plants. Previous studies indicate that caffedymine inhibits P-selectin expression via increasing cAMP through beta-2 adrenoceptors, but the inhibition was only partially repressed by beta-2 adrenoceptor antagonists, suggesting additional mechanisms underlying the inhibitory effect. Therefore, in this study, the effect of caffedymine and its analogues (N-caffeoyltyramine, N-feruloyltyramine, N-coumaroyltyramine, N-cinnamoyltyramine) on COX enzymes (I and II) was investigated, because COX enzymes are deeply involved in regulating P-selectin expression on human platelets. The decreasing order of COX-I inhibitory activity was caffedymine > N-caffeoyltyramine > N-feruloyltyramine > N-coumaroyltyramine > N-cinnamoyltyramine. Caffedymine was the most potent compound tested, able to inhibit COX-I enzyme activity by 43% (P < 0.013) at the concentration of 0.01 mu M. At the same concentration, caffedymine was also able to inhibit COX-II enzyme activity by 36% (P < 0.015), and the decreasing order of COX-II inhibitory activity was similar as that of COX-I. As a result of the COX inhibition, the production of thromboxane B2 (thromboxane A2 derivative) also decreased significantly in mouse blood treated with caffedymine and its analogues (0.05 mu M). Caffedymine and N-caffeoyltyramine, both with potent COX inhibitory activity, were also able to inhibit P-selectin expression and platelet-leukocyte interactions. These data indicate that COX inhibition is likely to be another mechanism for caffedymine to inhibit P-selectin expression on platelets.

The phytoalexin-associated response of different peanut genotypes to exogenous invasion in the field has not been investigated and may be useful for breeding resistant peanut cultivars. Five peanut genotypes, Georgia Green, Tifton 8, C-99R, GK-7 High Oleic, and MARC I, which differ in resistance to major peanut diseases, were investigated for their ability to produce phytoalexins under field conditions in South Georgia in 2001 and 2002. Five known peanut phytoalexins, trans-resveratrol, trans-arachidin-1, trans-arachidin-2, trans-arachidin-3, and trans-3'-isopentadienyl-3,5,4'-trihydroxystilbene, were quantitated. The phytoalexins were measured in peanuts of different pod maturity (yellow, orange, brown, and black) with or without insect pod damage (externally scarified or penetrated). Kernels from insect-damaged pods of C-99R and Tifton 8 genotypes had significantly higher concentrations of phytoalexins than other genotypes. The same genotypes were the most resistant to tomato spotted wilt virus and late leaf spot, while MARC I, which is highly susceptible to these diseases, produced very low concentrations of phytoalexins. However, there was no significant difference in phytoalexin production by undamaged peanut pods of all tested genotypes. trans-Arachidin-3 and trans-resveratrol were the major phytoalexins produced by insect-damaged peanuts. In damaged seeds, the concentrations of trans-3'-isopentadienyl-3,5,4'-trihydroxystilbene were significantly higher in Tifton 8 as compared to other genotypes. There was an association between total phytoalexin production and published genotype resistance to major peanut diseases. Stilbene phytoalexins may be considered potential chemical markers in breeding programs for disease-resistant peanuts. C1 USDA, ARS, Natl Peanut Res Lab, Dawson, GA 39842 USA.

The regiospecific ions used were from the loss of alpha,beta-unsaturated fatty acid specific at the sn-2 position. The content of 1,3-diricinoleoyl-2-oleoyl-sn-glycerols (ROR) among the three stereospecific isomers, RRO, ROR and ORR, was about 91%. The contents of other 1,3-diricinoleoyl-2-acyl-glycerols among the three stereospecific isomers were as follows: 1,3-diricinoleoyl-2-linoleoyl-sn-glycerol, 95%; 1,3-diricinoleoyl-2-linolenoyl-sn-glycerol, 96%; 1,3-diricinoleoyl-2-stearoyl-sn-glycerol, 96%; 1,3-diricinoleoyl-2-palmitoyl-sn-glycerol, 78%; and 1,3-diricinoleoyl-2-lesqueroloyl-sn-glycerol, 31%. These non-hydroxyl fatty acids were mostly at the sn-2 position of triacylglycerols in castor oil. These results suggest that phospholipase A(2) hydrolysis of phosphatidylcholine (PC) containing non-hydroxyl fatty acid at the sn-2 position is either blocked or partially blocked in vivo. Phospholipase A(2) hydrolysis of 2-lesqueroloyl-PC is not blocked and is similar to that of 2-ricinoleoyl-PC. Transgenic inhibition of phospholipase C hydrolysis of PC might be used to block the incorporation of non-hydroxyl fatty acids into triacylglycerols, thus increasing the content of ricinoleate in seed oil.

The phosphonate reagents, diethyl ethylformyl-2-phosphonate dimethylhydrazone and diethyl 1-propylformyl-2-phosphonate dimethylhydrazone, contained a protected aldehyde group instead of the usual ester group. A homologation cycle entailed condensation of the reagent with the starting aldehyde, followed by removal of the dimethylhydrazone protective group with a biphasic mixture of dilute HCl and petroleum ether. This robust two-step process replaces the standard three-step aldehyde homologation route using ester-based Horner-Wadsworth-Emmons reagents. The new synthesis of compound 1 from (2E)-2-methyl-2-butenal was run on a 10-g scale and required just five steps (two cycles of condensation and deprotection, followed by a final Wittig olefination) instead of the usual seven. In addition, the Wittig olefination step was simplified and its E-isomer selectivity was improved. The overall yield for the entire synthetic pathway was increased from 20% to 37%, enhancing the commercial potential of Carpophilus pheromones.

The inclusion of protein promoted molecular interactions, resulting in a well-organized homogeneous structure, as revealed by scanning electron microscopy and fracture-acoustic emission analysis. The resultant composite films showed an increase in stiffness and strength and a decrease in water solubility and water vapor transmission rate, in comparison with films cast from pectin alone. The composite films inherited the elastic nature of proteins, thus being more flexible than the pure pectin films. Treating the composite films with glutaraldehyde/methanol induced chemical cross-linking with the proteins and reduced the interstitial spaces among the macromolecules and, consequently, improved their mechanical properties and water resistance. Treating the protein-free pectin films with glutaraldehyde/methanol also improved the Young's modulus and tensile strength, but showed little effect on the water resistance, because the treatment caused only dehydration of the pectin films and the dehydration is reversible. The composite films were biodegradable and possessed moderate mechanical properties and a low water vapor transmission rate. Therefore, the films are considered to have potential applications as packaging or coating materials for food or drug industries.

To test the influence of feruloylation on cell wall degradability by human intestinal microbiota, nonlignified primary cell walls from maize cell suspensions, containing various degrees of ferulate substitution and diferulate cross-linking, were incubated in nylon bags in vitro with human fecal microbiota. Degradation rates were determined gravimetrically, and the cell walls were analyzed for carbohydrates, ferulate monomers, dehydrodiferulates, dehydrotriferulates, and other minor phenolic constituents. Shifting cell wall concentrations of total ferulates from 1.5 to 15.8 mg/g and those of diferulates from 0.8 to 2.6 mg/g did not alter the release of carbohydrates or the overall degradation of cell walls. After 24 h of fermentation, the degradation of xylans and pectins exceeded 90%, whereas cellulose remained undegraded. The results indicate that low to moderate levels of ferulates and diferulates do not interfere with hydrolysis of nonlignified cell walls by human gut microbiota.

Carniel, Elisabeth Ravel, Jacques TI Multiple Antimicrobial Resistance in Plague: An Emerging Public Health Risk SO PLOS ONE LA English DT Article AB Antimicrobial resistance in Yersinia pestis is rare, yet constitutes a significant international public health and biodefense threat. In 1995, the first multidrug resistant (MDR) isolate of Y. pestis (strain IP275) was identified, and was shown to contain a self-transmissible plasmid (pIP1202) that conferred resistance to many of the antimicrobials recommended for plague treatment and prophylaxis. Comparative analysis of the DNA sequence of Y. pestis plasmid pIP1202 revealed a near identical IncA/C plasmid backbone that is shared by MDR plasmids isolated from Salmonella enterica serotype Newport SL254 and the fish pathogen Yersinia ruckeri YR71. The high degree of sequence identity and gene synteny between the plasmid backbones suggests recent acquisition of these plasmids from a common ancestor. In addition, the Y. pestis pIP1202-like plasmid backbone was detected in numerous MDR enterobacterial pathogens isolated from retail meat samples collected between 2002 and 2005 in the United States. Plasmid-positive strains were isolated from beef, chicken, turkey and pork, and were found in samples from the following states: California, Colorado, Connecticut, Georgia, Maryland, Minnesota, New Mexico, New York and Oregon. Our studies reveal that this common plasmid backbone is broadly disseminated among MDR zoonotic pathogens associated with agriculture. This reservoir of mobile resistance determinants has the potential to disseminate to Y. pestis and other human and zoonotic bacterial pathogens and therefore represents a significant public health concern.

James TI Dietary copper supplementation reverses hypertrophic cardiomyopathy induced by chronic pressure overload in mice SO JOURNAL OF EXPERIMENTAL MEDICINE LA English DT Article ID ISCHEMIC HEART-DISEASE; CARDIAC-HYPERTROPHY; MYOCARDIAL-INFARCTION; SUPEROXIDE-DISMUTASE; TRACE-ELEMENTS; DEFICIENCY; ZINC; METALLOTHIONEIN; ANGIOGENESIS; MAGNESIUM AB Sustained pressure overload causes cardiac hypertrophy and the transition to heart failure. We show here that dietary supplementation with physiologically relevant levels of copper (Cu) reverses preestablished hypertrophic cardiomyopathy caused by pressure overload induced by ascending aortic constriction in a mouse model. The reversal occurs in the continued presence of pressure overload. Sustained pressure overload leads to decreases in cardiac Cu and vascular endothelial growth factor ( VEGF) levels along with suppression of myocardial angiogenesis. Cu supplementation replenishes cardiac Cu, increases VEGF, and promotes angiogenesis. Systemic administration of anti-VEGF antibody blunts Cu regression of hypertrophic cardiomyopathy. In cultured human cardiomyocytes, Cu chelation blocks insulin-like growth factor (IGF)-1- or Cu-stimulated VEGF expression, which is relieved by addition of excess Cu. Both IGF-1 and Cu activate hypoxia-inducible factor (HIF)-1 alpha and HIF-1 alpha gene silencing blocks IGF-1- or Cu-stimulated VEGF expression. HIF-1 alpha coimmunoprecipitates with a Cu chaperone for superoxide dismutase-1 (CCS), and gene silencing of CCS, but not superoxide dismutase-1, prevents IGF-1- or Cu-induced HIF-1 alpha activation and VEGF expression. Therefore, dietary Cu supplementation improves the condition of hypertrophic cardiomyopathy at least in part through CCS-mediated HIF-1 alpha activation of VEGF expression and angiogenesis.

An understanding of the factors that control the efficiency with which forest canopies harvest available light to fix carbon via photosynthesis is therefore necessary for the development of useful production efficiency models. We present an analysis of observations of daily LUE for 2004 in a northern hardwood stand at the Bartlett Experimental Forest CO2 flux tower, White Mountains, New Hampshire (USA). We used eddy covariance measurements to estimate gross carbon exchange (GCE), and radiometric instruments mounted above and below the canopy to estimate the fraction of incident photosynthetically active radiation absorbed by the canopy (fAPAR). Both GCE and fAPAR show strong seasonal and day-to-day variability that contribute to temporal variation in LUE. During the middle of the growing season, when fAPAR is relatively constant, day-to-day variation in LUE is largely explained (r(2) = 0.85) by changes in the ratio of diffuse to total downwelling radiation, but is not strongly correlated with any other measured meteorological variable. We also calculated top-of-canopy NDVI based on measurements of reflected radiation at 400-700 and 305-2800 nm. Seasonal variation in this broadband NDVI paralleled that of the 500 m MODIS pixel containing the flux tower. The relationship between broadband NDVI and fAPAR is approximately linear during green-up, but non-linear during autumn senescence. This seasonal hysteresis has implications for the use of remote sensing indices (such as NDVI or EVI) in satellite estimation of fAPAR for production efficiency modeling. (c) 2006 Elsevier B.V.

TI A processing method for weighing lysimeter data and comparison to micrometeorological ETo predictions SO AGRICULTURAL WATER MANAGEMENT LA English DT Article DE evapotranspiration; weighing lysimeter; micrometeorology ID EVAPOTRANSPIRATION EQUATIONS AB Weighing lysimeters make direct measurements of water loss from a growing crop and the soil surface around a crop (evapotranspiration, ET), and thus, provide basic data to validate other ET prediction methods. The objective of this study was the improvement of the lysimeter data processing to eliminate bad data and minimize the effect of random variations in the measurements. Also, grass evapotranspiration rates (ETo) were compared with evapotranspiration rates predicted from data taken at a nearby weather station that is part of the California Irrigation Management Information System (CIMIS). Hourly data for a 2-year period from a grass lysimeter located at Five Points, California were screened to remove questionable data and data taken on rainy days (38% of all data). The hourly ETo rate was calculated for the remaining data from lysimeter mass measurements using a seven-point Savitsky-Golay (S-G) approximation of the derivative at the central point. The data were plotted against the CIMIS hourly ETo predictions using the Pruitt-Doorenbos (PD) model and the least-squares best-fit line was close to the 1:1 line indicating that CIMIS PD predictions were reasonably accurate for this time period. Comparing the S-G method with a two-point finite difference method, the S-G method reduced the root-mean-squared error between lysimeter ETo and CIMIS predictions from 0.112 for the two-point method to 0.074 mm h(-1). Slopes of zero-intercept, best-fit lines to CIMIS PD versus lysimeter ETo for data representing each hour during the day exceeded unity from 9:00 a.m. to 4:00 p.m. but were less than unity at other times. An improved daytime result was obtained with the CIMIS Penman-Monteith (PM) model. The daytime soil heat flux calculated by the PM model is not included in the PD model and could account for this improvement. Correlation of hourly CIMIS and lysimeter ETo was poor during the night so CIMIS hourly ETo predictions at this site could be improved by characterization of factors that would improve prediction of ETo at night. Daily CIMIS ETo predictions were in good agreement with daily lysimeter ETo measurements for ETo < 6 mm d(-1) but tended to be smaller when ETo > 6 mm d(-1). (c) 2006 Elsevier B.V.

Five forages (tall wheatgrass, paspalum, creeping wildrye, bermuda-grass and alfalfa) were evaluated in a greenhouse study to compare forage species for biomass yield, mineral composition, and quality as ruminant feeds when irrigated with freshwater (ECw = 0.85 dS/m) and saline DW (ECw = 11 and 18 dS/m) and grown in a field soil mix characteristic of the drainage-imp aired areas. Tall wheatgrass was highly salt-tolerant with a relative yield of 85% under high salinity, whereas the relative yield of alfalfa was 43%. Metabolizable energy (ME in MJ/kg DM), the potential energy that the ruminant can obtain from consuming the forage, was higher in this greenhouse study as compared to our prior field study (Suyama et al., 2006). ME differed among the forage species and was ranked as: tall wheatgrass and alfalfa > paspalum > bermudagrass and creeping wildrye. All forages were deemed suitable as feeds for beef cattle and goats fed at maintenance energy levels. However, with long term consumption, the high selenium and sulfur content of these forages could potentially affect animal physiology, unless they were fed in a mixed ration. (c) 2006 Elsevier B.V.

Daily crop evapotranspiration was estimated using basal and canopy reflectance-based crop coefficients, and a hydrologic water balance was conducted in the plant root zone. Independent measurements of actual soil moisture measurements were made by neutron probe and gravimetric methods, and used to validate the simulated results. The results validate the reflectance-based crop coefficient method. High resolution multispectral aerial imagery was used to highlight the spatial variability of actual crop water demand in the study fields. (c) 2006 Elsevier B.V. All rights reserved.

TI Crop coefficients of open-canopy pecan orchards SO AGRICULTURAL WATER MANAGEMENT LA English DT Article DE crop coefficient; eddy covariance; effective canopy cover; one propeller eddy covariance; open canopy; pecan; physiological tree growth model; remote sensing ID IRRIGATED PECANS; MODEL; HEAT; FLUX AB Pecan [Carya illinoinensis (Wangehn.) K. Koch] production is an essential component of irrigated agriculture in and southwestern USA. Pecan consumptive water use is high compared to other crops. For irrigation purposes, consumptive water use (ETc) or evapo-transpiration is estimated from ETC = Kc ETr where Kc is the crop coefficient used to adjust the known reference crop evapotranspiration (ETr). The Kc of pecans, the ratio of ETc and ETr, varies according to tree age, tree spacing, growth stage within a season, and local weather conditions. The equation for Kc that is applicable to closed-canopy pecan orchards (i.e., for Kc(max)) is available from the literature. However, there is a lack of a method to calculate open-canopy pecan Kc according to tree size and spacing (varying effective canopy cover, ECC). The objective of this study was to derive a regression relationship in the form Kc = Kc(max) f(ECC) or Kc/Kc(max) = f(ECC) for open-canopy pecan orchards assuming that Kc/Kc(max) affected mainly by ECC. ECC was measured for orchards with different canopy covers using image analysis. Images were taken from a balloon and by satellite. Corresponding ETc values from the various pecan orchards were measured or estimated using four methods: (1) one propeller eddy covariance (OPEC) technique, (2) eddy covariance (EC) system, (3) remote sensing technique, and (4) simulations from a climate-based physiological tree model. Kc/Kc(max) was calculated for different ECC values as ETc/ETCmax where ETcmax is the closed-canopy ETc. A regression equation for open-canopy pecan orchards was obtained using data from OPEC, EC, and remote sensing techniques (Kc/Kc(max) = 1.33ECC, i.e., Kc = Kc(max) x 1.33ECC) and was found to be statistically significant (R-2 = 0.96, F = 2487, P < 0.001). The equation is consistent with the results from the physiological model and related literature. The Kc equation from this study can help pecan farmers and researchers get more accurate estimates of pecan irrigation requirements for open-canopy orchards. (c) 2006 Elsevier B.V.

Water-soluble cinnamon extract (CE) and HPLC-purified cinnamon polyphenols (CP) with doubly linked procyarridin type-A polymers display insulin-like activity. The objective of this study was to investigate the effects of cinnamon on the protein and mRNA levels of insulin receptor (IR), glucose transporter 4 (GLUT4), and tristetraprolin (TTP/ZFP36) in mouse 3T3-L1 adipocytes. Immunoblotting showed that CP increased IR beta levels and that both CE and CP increased GLUT4 and TTP levels in,the adipocytes. Quantitative real-time PCR indicated that CE (100 mu g/ml) rapidly increased TTP mRNA levels by approximately 6-fold in the adipocytes. CE at higher concentrations decreased IR beta protein and IR mRNA levels, and its effect on GLUT4 mRNA levels exhibited a biphasic pattern in the adipocytes. These results suggest that cinnamon exhibits the potential to increase the amount of proteins involved in insulin signaling, glucose transport, and anti-inflammatory/anti-angiogenesis response.

Recent cell culture studies have shown that IRSs can interact with, and are functionally required for, the transforming ability of many oncogenes. Consistent with this, IRSs are elevated and hyperactive in many human tumors. IRSs respond to many extracellular signals that are critical for mammary gland development, and we have shown that IRSs disrupt normal mammary acini formation in vitro, and cause mammary tumorigenesis and metastasis in vivo. In this review we will discuss the role of IRSs in both transformation and cancer progression. C1 Baylor Coll Med, Breast Ctr, Dept Med, Houston, TX 77030 USA.

TI Sorption of tetracycline and chlortetracycline on K- and Ca-saturated soil clays, humic substances, and clay-humic complexes SO ENVIRONMENTAL SCIENCE & TECHNOLOGY LA English DT Article ID ANTIBIOTIC-RESISTANCE; WASTE-WATER; OXYTETRACYCLINE; ENVIRONMENT; ENTEROCOCCI; MOBILITY; TYLOSIN AB Tetracycline (TC) and chlortetracycline (CTC) are used extensively for growth promotion and therapeutic purposes in livestock production. The sorption of TC and CTC on clays, humic substances (HS), and clay-humic complexes (clay-HC) derived from two agricultural soils was quantified using dilute CaCl2 (Ca) and KCl (K) as background solutions. In all systems, the soil components sorbed > 96% of added tetracyclines. Strongest sorption was observed for clays, followed by HS, and then clay-HC. Greater sorption by the Ca systems than the K systems and decreased sorption with increasing pH suggests that cation bridging and cation exchange contribute to sorption. X-ray diffraction analysis showed that TC and CTC were sorbed in the interlayers of smectites and that the presence of HS reduced interlayer sorption of tetracyclines by smectites in clay-HC. The results indicate that tetracyclines are dominantly sorbed on soil clays and that HS in clay-HC either mask sorption sites on clay surfaces or inhibit interlayer diffusion of tetracyclines.

Agronomic performance SO FIELD CROPS RESEARCH LA English DT Article DE grain yield; heterosis; male sterility; soybean ID COMBINING ABILITY; MALE-STERILE; SEED PROTEIN; HETEROSIS; GERMPLASM; GENETICS AB In soybean, manual cross-pollination to produce large quantities of F, hybrid seed for yield trials is difficult and time-consuming. Conversely, insect-mediated cross-pollination has been shown to produce large quantities of hybrid seed in soybean and could facilitate the identification of heterotic patterns. The objective of our study was: (1) evaluate F(1) hybrid soybean plants from single crosses for yield and agronomic traits over several environments and (2) compare hybrid performance of the single crosses to lines developed from three-way crosses and backcrosses. In 2003, F(1) seed of single-crosses and their parent lines were evaluated in replicated experiments at three locations. Also in 2003, three-way crosses, and BC(1)F(1) seed were produced. In 2004, three-way crosses, BC(1)F(1) crosses, and their parent lines were evaluated at one location. High-parent heterosis (HPH) in single-crosses for grain yield ranged from -41.11% to +11.19%; for protein content from -4.34% to +3.53%, and for oil content from -13.22% to -0.84%. In three-way crosses, HPH for yield ranged from -25.21% to -4.50%, for protein from -2.72% to +1.92%, and for oil from -5.87% to -1.20%. For BC(1)F(1) crosses, HPH for yield ranged from -15.65% to +41.97%, for protein from -2.57% to +1.69%, and for oil from -2.47% to +2.22%. Although positive heterosis levels were observed across all populations tested to determine the economic feasibility it is imperative that more tests of more cross-combinations be evaluated in replicated environments. Extensive research in different environments must be conducted to determine what parental combinations will produce the highest heterosis levels, and to develop criteria for selecting the parents with the best combining ability. This will be important to maximize agronomic performance that can economically justify the use of hybrids in soybean production. (c) 2006 Elsevier B.V. All rights reserved.

TI Simultaneous observations of the critical aeolian threshold of two surfaces SO GEOMORPHOLOGY LA English DT Article DE threshold; saltation; blown sand; wind erosion; aeolian research; dune; playa ID HIGH-PLAINS; SALTATION; TRANSPORT; TEXAS AB Threshold is an important parameter in wind erosion research and in the field of aeolian research in general. A new technique was recently developed that provides a means of determining threshold with a sampling system that continuously collects wind data along with critical information regarding saltation activity. By employing two identical sampling systems, it was possible to monitor the threshold of a highly mobile sand surface while simultaneously monitoring the threshold of a less mobile playa surface. Results indicate that threshold could be measured at both locations with enough precision to establish clear differences between the surfaces. The sandy surface at the Morgenstern Dunes site was considerably more active than the Yellow Lake playa site over the 113-day sampling period because of its consistently lower threshold. The Morgenstern site tended to maintain a fairly constant threshold of around 5.4 to 5.5 m/s whereas the threshold of the Yellow Lake playa surface varied from a low of 6.4 m/s to values greater than 13.3 m/s. Limitations of this method lie in the fact that threshold can be determined only when winds are blowing sufficiently strongly to cause sediment transport. (c) 2006 Elsevier B.V. All rights reserved.

Eroding streamside glacial drift, including glaciolacustrine deposits, were examined to help explain variations in the proportional contributions made by bank erosion. Sediment sources were quantified by comparing concentrations of the bomb-derived radionuclide (137)Cs in fluvial sediment with sediment from potential source areas such as agricultural soils, forest soils and stream banks. To compare sediment sources in streams containing abundant deposits of fine-grained glacial drift with watersheds that lacked moderate or extensive streamside deposits, samples were taken from 15 watersheds in the region. The mean contribution of bank erosion to sediment loads in the six streams with glaciolacustrine deposits was 60% (range 46-76%). The proportional contribution of bank erosion was also important in one stream lacking glaciolacustrine deposits (57%) but was less important in the remainder, with contributions ranging from 0 to 46%. Data from this study on the varying contributions of bank erosion and data from past studies of sediment yield in 15 watersheds of New York State suggest that eroding streamside glacial deposits dominate sediment yield in many watersheds. In other watersheds, past impacts to streams, such as channelization, have also resulted in high levels of bank erosion. Copyright (c) 2007 John Wiley & Sons, Ltd.

TI Support vector machines for recognition of semi-arid vegetation types using MISR multi-angle imagery SO REMOTE SENSING OF ENVIRONMENT LA English DT Article DE MISR; support vector machine; semi-arid vegetation; classification; multi-angle observations ID REFLECTANCE CSAR MODEL; BIDIRECTIONAL REFLECTANCE; CLASSIFICATION; SURFACE; AVHRR; BRDF AB Accurately mapping community types is one of the main challenges for monitoring and and semi-arid grasslands with remote sensing. The multi-angle approach has been proven useful for mapping vegetation types in desert grassland. The Multi-angle Imaging Spectro-Radiometer (MISR) provides 4 spectral bands and 9 angular reflectance. In this study, 44 classification experiments have been implemented to find the optimal combination of MISR multi-angular data to mine the information carried by MISR data as effectively as possible. These experiments show the following findings: 1) The combination of MISR's 4 spectral bands at nadir and red and near infrared bands in the C, B, and A cameras observing off-nadir can obtain the best vegetation type differentiation at the community level in New Mexico desert grasslands. 2) The k parameter at red band of Modified-Rahman-Pinty-Verstraete (MRPV) model and the structural scattering index (SSI) can bring useful additional information to land cover classification. The information carried by these two parameters, however, is less than that carried by surface anisotropy patterns described by the MRPV model and a linear semi-empirical kernel-driven bidirectional reflectance distribution function model, the RossThin-LiSparseMODIS (RTnLS) model. These experiments prove that: 1) multi-angular reflectance raise overall classification accuracy from 45.8% for nadir-only reflectance to 60.9%. 2) With surface anisotropy patterns derived from MRPV and RTnLS, an overall accuracy of 68.1% can be obtained when maximum likelihood algorithms are used. 3) Support Vector Machine (SVM) algorithms can raise the classification accuracy to 76.7%. This research shows that multi-angular reflectance, surface anisotropy patterns and SVM algorithms can improve desert vegetation type differentiation importantly. (c) 2006 Elsevier Inc..

Cryptosporidium bovis and Cryptosporidium deer-like genotype were much more prevalent in the post-weaned animals. It is not clear whether the same infection pattern also occurs in other geographic areas. In this study, to determine whether the same Cryptosporidium infection pattern was present in other geographic areas, we genotyped Cryptosporidium specimens collected from two farms in China and India, using specimens from farms in Georgia, USA for comparison. C. bovis was the most common species found in pre- and post-weaned calves in all three areas. In Georgia, the deer-like genotype was found frequently in pre- and post-weaned calves and Cryptosporidium andersoni was found in one post-weaned calf. Both C. bovis and the deer-like genotype were found in the few milking cows examined in Georgia. There were no differences in the small subunit rRNA gene sequences obtained from C. bovis or deer-like genotype among the three areas. One adult yak in China, however, was infected with a species similar to C. bovis, with only three nucleotide mutations in the target gene. All four common bovine Cryptosporidium spp. were differentiated from each other by restriction fragment length polymorphism analysis of PCR products with enzymes SspI and MboII. Thus, both C. bovis and the deer-like genotype are found in all age groups of cattle in diverse geographic areas and host adaptation of C. bovis might have occurred in yaks.

Five-week-old chickens were assigned to four groups (GT 0.5%, GT 2.0%, untreated/infected and non-infected control) and each group consisted of 15 chickens. Chickens were fed a standard diet supplemented with ground green tea for 2 weeks prior to infection with E. maxima (10,000 sporulated oocysts per bird). The effects of green tea on E. maxima infection were assessed by two parameters, fecal oocyst shedding and body weight gain. The green tea-fed chickens produced significantly reduced fecal oocysts (P < 0.05) when compared to the E. maxima-infected group fed standard diet. The green tea-based diet, however, did not improve body weight loss caused by E. maxima infection. This study is the first to demonstrate anticoccidial effect of green tea on Eimeria parasites.
